Shared and Non-Shared Events

Events, using a psychological approach, could either be shared or non-shared. Based on the denotation of shared and the non, one might have a pretty good idea of what the terms actually mean. One thing is for sure, though; apparently, not all events can be shared, which somehow contradicts one connotation of the word event. At any rate, this paper would define and differentiate shared and non-shared events as much as the author knows it. Shared EventsIn order to understand what the term means without the use of complex psychology books, we should make do with just the bare words themselves defined separately: Shared is the past tense of share, which means to allow joint access to a particular thing or concept. Anything can practically be shared—even personal things, if it is within one’s hygienic tolerance. An event, meanwhile, is anything happening. So, combining the two definitions, we would get anything happening that is experienced by not just a single person therefore, our bare definition of a shared event is formed.Adding the subject of psychology, a shared event is something that is experienced by all parties involved, but its significance impacts those of not just by one person but all those involved in the event. Non-Shared Events Since the definition of shared events is already established, we only need to define the word non in order to get our full definition of a non-shared event. The word non is an adverb that signifies that the word following it should be regarded as the contrary.Therefore a non-shared event is exactly the opposite of a shared event, which brings us to a definition of anything happening that is experienced by just a single person. Again, from a psychological perspective, we get â€Å"something happening, whose impact only affects one individual. Examples of Shared Events There are many examples of a shared event. A good and timely example is none other than the current economic crisis. Is it an event? Check. Does it affect those involved? Check.The current economic crisis, call it recession if you must, is definitely a shared event, not only because it is an event (a big one at that), but also because virtually everybody is affected. Employees are either losing jobs or losing benefits, investors are losing their business, and families are giving up their homes. Another example of a shared event is a regional disaster—they could either be natural disasters or man-made. Hurricanes, earthquakes, forest fires, and floods are just some of examples of regional disasters that are shared by everyone who happened to be in the area where it took place.Election is another shared event that impacts the population, as the outcome of an election could determine the future of a nation. Examples of Non-Shared Events There are also a number of examples for non-shared events. A person who gets himself or herself into an accident alone is one example. However, if that person is the provider for a family, his or her accident can be considered as a shared event, as that person’s accident would cause his or her family to be affected financially by the accident.The same it true with a person who gets sick. If he lives alone or if his inactivity does not affect the welfare of the family, his sickness would be considered a non-shared event. Otherwise, it is a shared event. Relationship events outside of the family is also an example of a non-shared event—other family members do not necessarily have to get involved in relationship matters outside of their circle (Eley & Stevenson, 2000).

Management Information Systems and Its Importance

What you think Management of Information Systems is and why it is important in today’s business environment? Management Information Systems (MIS) is the term given to the discipline focused on the integration of computer systems with the aims and objectives on an organization. Modern businesses have been leveraging on MIS to manage, order, organize and manipulate the gigabytes and masses of information generated for various purposes. MIS helps businesses optimize business processes, address information needs of employees and various stakeholders and take informed strategic decisions.The development and management of information technology tools assists executives and the general workforce in performing any tasks related to the processing of information. MIS and business systems are especially useful in the collation of business data and the production of reports to be used as tools for decision making. With computers being as ubiquitous as they are today, there's hardly any la rge business that does not rely extensively on their IT systems (Kenneth C. Laudon).However, there are several specific fields in which MIS has become invaluable like in decision support systems, resource and people management applications, Enterprise Resource Planning (ERP), Supply Chain Management (SCM), Customer Relationship Management (CRM), project management and database retrieval applications. 1) Support Strategy: While computers cannot create business strategies by themselves they can assist management in understanding the effects of their strategies, and help enable effective decision-making. MIS systems can be used to transform data into information useful for decision making.Computers can provide financial statements and performance reports to assist in the planning, monitoring and implementation of strategy. MIS systems provide a valuable function in that they can collate into coherent reports unmanageable volumes of data that would otherwise be broadly useless to decisi on makers. By studying these reports decision-makers can identify patterns and trends that would have remained unseen if the raw data were consulted manually. MIS systems can also use these raw data to run simulations – hypothetical scenarios that answer a range of ‘what if’ questions regarding alterations in strategy.For instance, MIS systems can provide predictions about the effect on sales that an alteration in price would have on a product. These Decision Support Systems (DSS) enable more informed decision making within an enterprise than would be possible without MIS systems (Obrien). The other area which MIs support is data processing. 2) Data Processing: Not only do MIS systems allow for the collation of vast amounts of business data, but they also provide a valuable time saving benefit to the workforce.Where in the past business information had to be manually processed for filing and analysis it can now be entered quickly and easily onto a computer by a d ata processor, allowing for faster decision making and quicker reflexes for the enterprise as a whole. 3) Management by Objectives: While MIS systems are extremely useful in generating statistical reports and data analysis they can also be of use as a Management by Objectives (MBO) tool. MBO is a management process by which managers and subordinates agree upon a series of objectives for the subordinate to attempt to achieve within a set time frame.Objectives are set using the SMART ratio: that is, objectives should be Specific, Measurable, Agreed, Realistic and Time-Specific. The aim of these objectives is to provide a set of key performance indicators by which an enterprise can judge the performance of an employee or project. The success of any MBO objective depends upon the continuous tracking of progress. In tracking this performance it can be extremely useful to make use of an MIS system. Since all SMART objectives are by definition measurable they can be tracked through the gen eration of management reports to be analyzed by decision-makers.Advantages of MIS: The field of MIS can deliver a great many benefits to enterprises in every industry. Expert organizations such as the Institute of MIS along with peer reviewed journals such as MIS Quarterly continue to find and report new ways to use MIS to achieve business objectives. Better Planning and Control: MIS has to be designed and managed in such way that it aggregates information, monitors the company's activities and operations and enhances communication and collaboration among employees (Obrien). This ensures etter planning for all activities and better ways to measure performance, manage resources and facilitate compliance with industry and government regulations. Control helps in forecasting, preparing accurate budgets and providing the tools and vital information to employees, top management and business partners. Core Competencies: Every market leading enterprise will have at least one core competenc y – that is, a function they perform better than their competition. By building an exceptional management information system into the enterprise it is possible to push out ahead of the competition.MIS systems provide the tools necessary to gain a better understanding of the market as well as a better understanding of the enterprise itself. Enhance Supply Chain Management: Improved reporting of business processes leads inevitably to a more streamlined production process. With better information on the production process, comes the ability to improve the management of the supply chain, including everything from the sourcing of materials to the manufacturing and distribution of the finished product. Disadvantages of MIS:Depending on organization deployment, usage and extraneous factors, some disadvantages related to Management Information Systems can come to the fore. Allocation of budgets for MIS upgrades, modifications and other revisions can be quite tricky at times. If budge ts are not allocated uniformly or as per immediate requirements, key functionalities might get affected and benefits might not be realized consistently. Integration issues with legacy systems can affect the quality of output and vital business intelligence reports (Kenneth C. Laudon). Risks Associated With MIS:Risk reflects the potential, the likelihood, or the expectation of events that could adversely affect earnings or capital. Management uses MIS to help in the assessment of risk within an institution. Management decisions based upon ineffective, inaccurate, or incomplete MIS may increase risk in a number of areas such as credit quality, liquidity, market/pricing, interest rate, or foreign currency. A flawed MIS causes operational risks and can adversely affect an organization's monitoring of its fiduciary, consumer, fair lending, Bank Secrecy Act, or other compliance-related activities.Since management requires information to assess and monitor performance at all levels of the organization, MIS risk can extend to all levels of the operations. Additionally, poorly programmed or non-secure systems in which data can be manipulated and/or systems requiring ongoing repairs can easily disrupt routine work flow and can lead to incorrect decisions or impaired planning (Obrien). Constant Monitoring Issues: Change in management, exits or departures of department managers and other senior executives have a broad effect on the working and monitoring of certain organization practices including MIS systems.Since MIS is a critical component of an organization's risk management strategy and allied systems, constant monitoring is necessary to ensure its effectiveness (Obrien). Quality of inputs into MIS needs to be monitored; otherwise consistency in the quality of data and information generated gets affected. Managers are not able to direct business, operational and decision-making activities with the requisite flexibility.Bibliography Kenneth C. Laudon, J. P. (n. d. ). Management Information Systems.

Victim Impact Statement

Victim Impact Statement – Drafted by Blanche Dubois Creative Writing Task – English HL Divya Jethwani (12B) Victim Impact Statement – Drafted by Blanche Dubois Creative Writing Task – English HL Divya Jethwani (12B) Your honor, I, Blanche DuBois am here today, as your living example of how a cruel crime can affect a person so radically, bringing in a change so drastic causing them to feel alienated and unwanted.The case with regard to my rape that we address in the court today may just be in relation to a sole crime committed by my darling sister’s husband, Stanley Kowalski; however, in all honesty I feel that I have been victimized right from the day I arrived at their residence at Elysian Fields. It may be a little too late according to the law to discuss a crime almost 5 years after it was committed, however that would only be in order if this crime and its effects were subdued instantly.Although, obviously that wasn’t the case, and eviden tly I am still suffering from the consequences of other people’s actions, I am still labeled as the person who is mentally imbalanced and furthermore, I don’t have enough money to pay off my debts for my stay at the recuperation center anymore. Who is going to restore my reputation? Who is going to pay off these bills that were generated for my recovery after my assault? How do I feel, after all these years, now that I am finally out of the four-walled room in the mental asylum that felt like prison? I feel incompetent, I feel redundant, I feel damaged and lastly I feel broken beyond repair.The years have passed by, but me; I’m still stuck in time, still stuck in that moment when I was whisked away to a mental asylum in opposition to my belief that I was going away with the handsome Shep Huntleigh. Is this fair your honor? Can the emotional scars that are now engraved on me be justified? It is possible to say that I might have been remotely imbalanced earlier du e to my disposition after the loss of our ancestral home, Belle Reve and I also lost my reputation and status back in Laurel for indulging in inappropriate acts with several men. It is also true that I have lost my husband several years go and the loss has been absolutely unbearable causing me to turn to alcohol and other harmful habits, however when I arrived at Stella darling’s house, I expected to receive love, warmth and affection but all I was showered with in return was animosity and a cold shoulder from Stanley Kowalski. It may not have started with an instant hatred; in fact it didn’t start with hatred at all. Stanley appeared to be of a very flirtatious and playful nature on our first encounter. The polygamous type, who may have possibly been sexually attracted to more than one woman, I noticed it instantly but I didn’t let it get to me.I had a sense of respect for the man, after all he is my sister’s husband, however after his act of infidelity, all I can say is that all men are the same, all with selfish desires. The first time I noticed a change in Stanley’s behavior was after the realization that we lost Belle Reve. He started to doubt me, started to believe that I had squandered away the money from the sale of Belle Reve and that I was lying to him and my sister. I do agree that I can be vain quite some times, however I can assure you all present here today I could never be so deceitful to perform such a venal act.The fact that this had planted a seed of doubt in Stanley’s mind started to make me nervous, my insecurities started to emerge and I could not handle this attack on me as a person. Stanley changed so drastically over such a short period of time, and suddenly I know that he has attacked my poor baby sister and planted a slap on her face. Which gentleman does that to his wife during pregnancy your honor? Can this even be considered a human act? Forget slapping your wife during her pregnancy, how c an one explain an act of adultery with your wife’s sister when she is going through labor in the hospital that very night?Chivalry is dead your honor chivalry is dead! That night when my little doll was suffering in hospital delivering his baby, Stanley came home to celebrate the happiness of the new life in the world and instead of celebrating together the birth of this child, the night turned into that of regret, hate and abuse. Stanley thoughtlessly abused my weakness and the fact that I was helpless and couldn’t shout for help at all. He was ruthless; he started yelling at me, called me a dreamer and told me I was imagining all the things that were happening to me and then when I tried to run away from him, he stopped me, blocked my way and I was helpless.I couldn’t run! And then he indignantly assaulted me in my sister’s house†¦ how am I supposed to feel your honor? Stanley Kowalski’s behavior is downright disgusting and filthy. This man is the reason for all the suffering my baby sister faces to date even after the birth of her child. I cannot handle to see her like this your honor, my baby sister; she’s the apple of my eye. Please help her, please help us, and please understand. Punish this brute rightly with the worst punishment ever for this sort of behavior.Your honor, we depend on you and the law for the correct judgment and punishment for all the pain and grief the beast has caused us.

ISOLATION AND CHARACTERISATION OF LYMPHOCYTES Lab Report

ISOLATION AND CHARACTERISATION OF LYMPHOCYTES - Lab Report Example This is because this results in an inaccurate count. The same is true if the cover slip is moved after the sample is loaded. To make randomized counting only the 4 squares at each end were picked and then the 16 small squares within each large square, that is, in an organized zigzag along the rows. To make the counting standardized only cells lying on the bottom and right hand boundary were counted in and a cell lying on the top or left hand boundary were not counted in. This was in order to avoid counting cells twice. Normally, at least two squares should be counted, comprising more than 100 cells within each central counting area of every square. For higher accuracy, additional cells can be counted and the mean used to compute cell concentration. The result of cells counts were in the table 1 below. The other cells in the splenocyte preparation are red cells 3.82%, Granulocytes 6.1% as shown in the table 4 above. The abundance of small lymphocytes shows that the cell suspension has more immature cells which are maturing in the spleen to become large lymphocytes and T-lymphocytes. With time the population of small lymphocytes decreases as they develop to large lymphocytes, medium lymphocytes and T-lymphocytes. The spleen is made up of immune lymphocytes and that why in this experiment there were low number of other types of cells. Time was very important in this lab because long exposure could lead to lack of the reliability. This is because the population of splenocytes keep on changing since some cell has not matured fully and other are multiplying. For this lab the time limit was hour since In this lab exercise, Nigrosin was used to stain any dead cells. Nigrosin is an acidic stain. This means the stain readily gives up a hydrogen ion and becomes negatively charged. Since the surface of dead cells is negatively charged, the cell surface repels the stain. Thus slide glass will stain, but the dead cell will not. The dead

What are the benefits of using simulation to teach nursing Essay

What are the benefits of using simulation to teach nursing - Essay Example Additionally, simulation display actions, conclusion and important opinion through techniques like role playing, use manikins and videos to enhance confidence and clinical skills at multiple levels of nursing practice. There are diverse benefits of using simulation to teach nursing. For instance, simulation training practice enables nursing students develop accuracy in diagnosis and treatment of patients. This helps students to develop their ability to learn and retain knowledge therefore, enhancing patient safety as theoretical and conceptual learning are practically implemented allowing student apply learned concepts. Jeffries (2005) infers that skill performance, critical thinking, satisfaction and knowledge are addressed though simulation and in turn competence among the practicing nursing students is developed. The underpinning factor therefore, is that simulation training offers student opportunities to practice interventions in a safe and sound environments, observe consequences when incorrect conclusion are made and with new developing trends in the nursing profession where time, accuracy and due diligence form the key pillars to service delivery, healthcare providers need better understanding to foster smooth transition to clinical experiences and through simulated practices adaptability to clinical environment is reached as consistent practical approaches are used to engage student (Schmidt & Brown, 2007). Simulation practices are used to challenge and support students develop and learn prioritization, teamwork, delegation, communication and leadership and in so doing transforming clinica l environment by providing institutions with the flexibility to create specific and unique learning experiences not duplicable in real clinical environment. In adapting to simulation as a style to teach nursing several challenges present themselves therefore hindering full adoption of the style by various institutions.

Question - Research Paper Example Lastly, experiments can be repeated for a number of times with different sample sizes until the expected outcome is achieved. Surveys on the other hand are not quite reliable since they will cost more while being repeated. Content analysis is best suited for social science studies that highly rely on research based on already existing literature. According to Babbie (2010), it is "the study of recorded human communications such as books, websites, paintings and laws†. Ethical considerations are also very essential while conducting a study. According to the APA (2002), five principles should be implemented by the researcher. These include: Participant should be informed of intellectual property (IP) rights. Researcher should follow informed – consent rules. Researcher should be professional. Researcher should practice confidentiality. Researcher should be capable of solving ethical dilemmas. Some of the limitations with regard to the experiment include human error. Sectio n 2: SAMPLING The participants who will be sampled include students from the different levels in the college. The number of participants will be controlled to 40 participants. These participants will be randomly selected – A random sampling technique will be used. The population of interest is individuals aged from 18 to 37 years. In addition to that, there will be other secondary sources of information that will be used so as to support the evidence being studied. That is, the secondary resources will act as additional literature entries. It should be noted that having a controlled sample size is key in every study. This is in a bid to prevent the experiment from being extremely tedious, uncontrolled as well as preventing the use to too many resources. As a result, the sample size that has been selected will perfectly represent the targeted population. Limitations in the sample include: Type 2 errors, lack of statistical power, distribution inequalities and lack of significa nce. Section 3: KEY VARIABLES In this hypothesis testing, the variables under study include the age of the participants and the effect of instructor humour in student learning. The age of the participants: It is without doubt that humour has its effect on different age groups differently. For example younger people may find humour important in student learning as compared to elder people. As a result, this is a variable that is very crucial in this testing. Effect of instructor humour: This is another variable that is important in this study. It will be used to determine which age group fancies humour in the learning environment. Independent variable: An independent variable is that which can be changed in a study. Largely, any experiment must have an independent variable. With regard to the hypothesis being tested, the independent variable is the impact of humour in student learning. As a result, the humour could be projected by the instructor or not. Dependent variable: This is a variable that solemnly depends on the independent variable. As a result, these variables act as functions of the independent variable. With regard to the hypothesis being tested, the dependent variable is the age of the participants. In the experiment, the hypothesis will be: â€Å"The effects of instructor humour on student learning† Section 4: ANALYSIS The level of measurement is a representation of the different methods in which numbers can be used in an experiment. There are four major levels of

Corporate Social Responsibility Essay Example | Topics and Well Written Essays - 2500 words - 1

Corporate Social Responsibility - Essay Example In this brief treatise, the history and evolution of CSR will be described and followed by a discussion on the concept and drivers of CSR. Focus is put on the role of CSR in the financial crisis, the implications of CSR for both business and communities, and the prospects of CSR for the future. History and Evolution of CSR While the concept of business corporations possessing some type of social accountability or obligation may have surfaced in the past, the serious study of corporate social responsibility as a facet of management commenced in the 1950s and was called by a host of other names (see Table 1). In 1953, Bowen posed the following question: ‘To what extent do the interests of business in the long run with the interests of society?’ (Bowen 1953, p. 5) The corporate responsibility core concept emerged as an economic concern. Andrew Carnegie, the founder of US Steel, articulated two principles supportive of CSR: (1) the ‘charity principle’ requiring individuals who have more to assist those who have less; and (2) the ‘stewardship principle’ stating that the rich and wealthy hold their wealth ‘in trust’ for the rest of society; while they hold it, they are required to multiply the wealth through making sound and prudent investments (Freeman & Liedtka 1991). Carnegie’s position was termed ‘richesse oblige’ by Windsor (2001), which is a parody of ‘noblesse oblige’. On the other side of the debate is the argument of Milton Friedman that corporations should pursue their economic self-interest and that CSR activities amount to a moral wrong against the shareholders. Activities directed at the social welfare should be properly left to the government (Freeman & Liedtka 1991). Friedman’s position resounded among many businesspeople and practitioners, understandably more than academicians, and the concept of wealth creation as the priority (some say only) goal for business constituted a recurring theme of many policy makers. At one point the argument entered the realm of academic discussion, and the debate eventually led to the conciliation of the two sides: ‘wealth creation is the best path to social welfare improvement’ (Windsor 2001, p. 226). This approach has been accepted by most businesspeople and managers because it resolves the duality imposed by Bowen’s premise that separates wealth and social responsibility. What it does not resolve is the direction management should take if a decision should be required between what may emerge to be irreconcilable alternatives (i.e. in favour of wealth creation or in favour of social responsibility). Currently, the main promoter of the ideas and principles of corporate social responsibility is the United Nations (Madrakhimova 2013, p. 115). Through the UN Guiding Principles on Business and Human Rights, the UN sought to advance global standards for business firms, particularly the large multinational corporations, to abide by in order to preserve and protect human rights that these businesses may be violating in the interest of earning a profit. Table 1: The genesis of the concept of corporate social responsibility (Madrakhimova 2013, p. 116) Concept of CSR CSR is a ‘concept whereby companies integrate social and environmental concerns in their business operations and their interaction with their stakeholders on a voluntary basis’

The Portrait Of Christ - Essay Example They want a straight message that is verifiable by evidence and testimonials. America is a complex society, with many educated and globally-aware citizens suffering just as much stress as those who are struggling on welfare or homeless, single parents or factory workers. Therefore, any message, in order to be relevant in such a complex society, will need to make people feel like there is a way out of stress, that there is hope. Americans are concerned about nuclear threat, terrorism, discrimination, financial stability, safety, pollution, cholesterol, the ozone layer, global warming, therapeutic issues, and a whole variety of threats. Consequently, Americans are a bit on the defensive side, meaning that they need to be approached gently, not further threatened. A fifth element that characterizes Americans is their friendliness, their outgoing style and willingness to help others, to share resources, so long as they are not taken undue advantage of. These five characteristics shape my argument for why the Gospel of John has such a compelling message and delivery style for Americans at the beginning of the 21st century. Mark’s portrait of Christ emphasizes his suffering and how believers share in his suffering. This is a portrait that Americans can relate to at times because, like everyone else, Americans are subject to the death and loss of friends and family members, housing foreclosures, cancer and other health problems, parenting issues, incidents with traumatic consequences.

Operations Management - Assignment Example Finally, they can be used to develop systems to automate the processes they model (Gieskes, 2001). In the last case, programmers may use the process model as a guide in developing the information system or more recently, some process models can be run though process execution engines that automate the process directly from the model. A great deal of customization is often required in simulation systems modeling. From initial appearance, no system bears exact semblance to another and each time a new model is to be developed, the designer is compelled to begin from scratch. Simulation presents designers with powerful modeling tools which help in coming up with efficient systems. Interesting, even with these tools at the modelers’ disposal, they still get the feeling that they are reinventing again and again. There is always the suspicion that maybe the model they are about to design already exists or may be there already exists a model that sufficiently resembles the model to be designed. Either way, simulation provides a useful tool through which systems can be simulated. A number of techniques are often used in implementation of simulations. This project explores a specific type of simulation, a discrete event-based simulation, whereby events take place according to a schedule set on the fly as simulation plays out, with the main aim being to focus on points in time whereby interesting events take place and skip the dead spots in between the processes. For sparse simulations, where only a few events occur at irregular intervals, event-based simulation is extremely efficient. In the simulation described in this report, the dry cleaning establishment’s inner workings are modeled. Although taking note of the fact that an actual dry cleaning establishment is a physical store which not only occupies physical space, but is also complete with machinery, workers, customers, and other variables, there are further complexities than a typical model can incor porate. This simulation therefore operated a simple model but still captured the entire essential ongoing in dry cleaning process. To keep the simulation simple and reasonable, it is assumed that all garments to be dry cleaned are identical in size, weight, and material despite the fact that realistic differences are available in the process. It is assumed that over the course of time, the difference will even out. An average time is assumed for the clothing. Spreadsheet model versus ARENA modeling Discrete event modeling/simulation is largely use in generation of system predictions of states during time intervals, which are flexible in examination of what if situations. For instance, it is regularly used in evaluation of client waiting lines often referred to as a queue. The question typical of such models and simulations is how long customer will have to wait (averagely) in a line before a customer representative attends to him/her and if this wait time is too long, explore possib le ways of reducing it. Solutions may include adding servers. Modeling and simulation help explore these questions without the need to actually create and assess a physical situation as such a move could prove extremely expensive. Among the approaches often adopted in modeling are spreadsheet modeling and ARENA modeling. A model spreadsheet is defined as a ubiquitous software packages element available on many networked as well as personal microcomputer systems. It is primarily applied in

Human Resources- Benefits Essay Example | Topics and Well Written Essays - 1750 words

Human Resources- Benefits - Essay Example Another benefit issue includes decreasing annual bonuses, cutting off maternity leave from 12 months to six months and making short the vacation time. In this plan, â€Å"the firm lends the employee funds to purchase the stock at fair market value â€Å"(Bhagat 1984 pg 197). The purpose of the plan is to offer eligible employees a chance to become shareholders in the company. It is assumed that employee participation in the ownership of the business will lead to common benefits for both the employees and the company. The company grants stock-based compensation to directors as well as employees. They issue new shares of Microsoft common stock to assure exercises of awards approved under all stock plans. They also have an employee stock purchase plan for all eligible employees. Shares of common stock will be purchased by employees at intervals of â€Å"90% of the fair market value† (Intricon Corporation 2011 pg 2) on the last day of each period. Employees might acquire shares having a value not exceeding 15% of their gross compensation during a proposed period.  But the company has announced it will reduce the discount employees that are to be given when they buy Microsoft stock. These benefit changes were made in order to decrease their operating costs and also increase the long-term value of the company. The employees will be able to acquire Microsoft stock at a 10 percent discount through Microsoft's Employee Stock Purchase Plan, compared with the current 15 percent discount. They will also be able to acquire stock through the plan each quarter, rather than twice a year. Microsoft needs to increase the stock purchase benefit plans as they facilitate the recruitment & retention of talented staff, promote an industrial environment and also offer a device for the arrangement of interests between employers and employees. For the growth of successful companies, these plans are likely to construct sustainable wealth for employees and their communities. Em ployee stock purchase plans will improve the employee productivity. Part 3: Literature Review Benefits play a significant function for an employer. The employees will work hard to make sure that their benefits replicate the varying needs and wants of the people and that is why most of the companies offer many industry-leading benefits to their employees who help in accomplishing the objectives of the organization. Employee benefits comprise of â€Å"all benefits and services, other than wages for time worked, that are provided to employees in whole or in part by their employers† (Beam & McFadden 2001 pg 4). Examples include medical insurance, paid vacation etc. There are various benefits provided by the US government to the employees such as medical protection, retired income etc. These benefits may be long term or short term, financial or non-financial, free of cost or available at concessional rates. They may include educational, residential, medical or recreational facilit ies. Such facilities maybe offered individually or in a group and within or outside the organization. Therefore, the employee benefits are reassurance along with the facilities provided which allows them to operate in a nourishing and passive environment. Most employers reimburse employees with some blend of cash plus benefits such as health assurance. An employer may decide to include benefits in the company’

Obama effectively uses logos to help voters understand the difference between his vision and the Republican vision. He reminds voters that they have a responsibility in choosing the right vision, which can be attained through thinking reasonably about what Republicans had done in the past. As former leaders, their policies contributed to the 2008 recession. Obama asserts his vision early in his speech: â€Å"Ours is a fight to restore the values that built the largest middle class and the strongest economy the world has ever known† (1). He is saying that the Republican vision does not offer a tangible road to the protection of the middle class and economic development. He argues that Republican policies are unclear: â€Å"They want your vote, but they don’t want you to know their plan† (2). This is effective if the voters will appreciate that it is better to take a more tangible new road from Obama than an unknown, possibly repetitive road from Republicans. More over, Obama appeals to reason when he emphasizes that people should not go back to Republicans, who have been doing the same things: â€Å"And that’s because all they had to offer is the same prescription they’ve had for the last thirty years† (2). Obama effectively reminds people that his road to economic recovery is new and ongoing. Furthermore, Obama underlines the importance of moving on and not comparing his work with past Republican administrations. He jokes about the tax resolutions of Republican administrations: â€Å"Have a surplus? Try a tax cut. Deficit too high? Try another† (2). Obama influences voters to understand that he is moving away from these tested-and-failed actions. He will continue his

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay The main aim of this report is to discuss the evidence for the protective effects of fluoride toothpastes and varnishes. In addition, I will discuss their application and mode of action. To begin with, I will give a brief history of fluoride and how it fits into the reversal of tooth decay. I will discuss fluoride varnishes namely Duraphat, Fluor Protector and Duraflor and their effect on the DMF Index and their roles in school based prevention programmes. There are other varnishes such as Lawefluor and Bifluorid but these are less commonly used and therefore, I will not be discussing them. After discussing fluoride varnishes, I will consider fluoride toothpastes. I will give a description on the composition of a typical toothpaste and the effect of fluoride toothpastes on the DMF Index. In addition, I will discuss the effects of high fluoride concentration toothpastes. Finally, I will compare both toothpastes and varnishes.

Fluoride is a negative ion of the element fluorine and is found naturally in water, foods, soil, and minerals such as fluorite (calcium fluoride) and fluorapatite. Fluoride can also be synthesised in laboratories where it can be added to oral hygiene products and to water. Fluoride utilisation has occurred in two phases: before water fluoridation in the 1950s and after the widespread use of fluoridated dentifrices in the 1980s (Cury, Tenuta 2008) when less than 10% of toothpastes contained fluoride compared with 96% at present. Fluoride is most effective post-eruptively (Oganessian, Lencova Broukal 2007) where the effects are generally topical and therefore, it is important for a constant fluoride concentration to be maintained in the oral environment. Topically applied fluoride provides high concentrations of fluoride to surfaces of the denti tion. This provides a local protective effect and prevents ingestion of large amounts of fluoride. (Marinho et al. 2004) Deposition of fluoride in enamel During apatite crystal formation, low concentrations of fluoride are incorporated into the tooth structure. This leads to supersaturation with respect to fluoridated hydroxyapatite: {{66 ten Cate,J.M. 2008) Ca10(PO4)6(OH)2+ F-= Ca10(PO4)6(F)2 + 2OH- (Fluorapatite) After calcification is complete and prior to eruption, additional fluoride is taken up by the surface enamel. After eruption, the enamel continues to take up fluoride from its oral environment leading to its profound topical effects (Kidd 2005). What is tooth decay? It is important to consider the causes of tooth decay and how fluoride can be used to reverse the carious process. Dental Caries is a multifactorial disease caused by the action of acidogenic and aciduric bacteria (Streptococcus Mutans and Lactobacilli ({{32 Featherstone,J.D. 2008}}) on fermentable carbohydrates such as sucrose. Salivary glycoproteins form a pellicle on the tooth to which these bacteria attach to forming a pathogenic biofilm and over time, acid demineralisation and proteolytic destruction of the organic component of the enamel and dentine takes place (Young, Kutsch Whitehouse 2009). Dental Caries can be classified in several ways According to location-Caries may be restricted to pits and fissures but may also progress to expose the pulp. Restorative status of the tooth- Primary caries occurs on previously unrestored teeth whereas secondary caries occurs at margins of restorations {{52 Kidd,Edwina A.M. 2005}}. Secondary caries is caused by local factors that are involved in the formation of cariogenic plaque. Most secondary carious lesions develop at the gingival margins of restorations primarily in areas of stagnation areas (Mjà ¶r, 1998). Large gaps between the restoration and the wall of the cavity preparation can create an environment that favours secondary caries formation (Mjà ¶r, 1998). Secondary caries is also known as recurrent caries. Caries can be arrested whereby a lesion which was previously active has now stopped progressing. Fluoride: Mode of Action Fig 1: Demineralisation Process and the role of fluoride (Cury, Tenuta 2008) Figure one shows how sugars such as sucrose, glucose and fructose are converted to acids in the plaque biofilm. When the pH decreases below 5.5 (critical pH of enamel), the saliva is no longer supersaturated with calcium and phosphate. Therefore, demineralisation occurs. However, in the presence of fluoride and if the pH is higher than 4.5, hydroxyapatite is converted to fluorapatite which has a lower solubility. As a result, net demineralization is reduced and the dental hard tissues are more acid resistant. Tenuta and colleagues calculated that fluorapatite would not dissolve until the pH dropped below approximately 4.4. However, researchers have found that the effect of fluoride is not only due to the decreased solubility but also due to the effect of fluoride on the rates of demineralisation and remineralisation (Stoodley et al. 2008). In order to enter bacteria, fluoride must be combined with a hydrogen ion forming hydrogen fluoride (HF), which readily diffuses into the cell. Once inside the bacterial cell, the HF dissociates into fluoride and hydrogen ions. The fluoride inhibits intracellular bacterial enzymes such as enolase. As a result, less phosphoenolpyruvate and lactate are formed. The reduced lactate formation limits the ability of bacteria to cause caries. Similarly, the uptake of glucose is also reduced by fluoride {{63 Featherstone,J.D. September 2004}}. The fluoride concentration in saliva increases after brushing with a fluoride toothpaste. After three minutes, the concentration is 100 times greater than the baseline value (normally 0.03ppm or 1.6umol/l) {{65 Murray, J.J 1991}}. Two hours later, the concentration returns to normal. It is important to avoid rinsing out the mouth as the most profound effects of fluoride are within two hours of brushing. Fluoride is spread throughout the oral cavity and is stored in compartments on the tooth surface and the remaining pellicle (Cury, Tenuta 2008). Calcium Fluoride globules are formed and are reservoirs of fluoride, releasing it as the pH falls, thereby, reducing time spent in the demineralisation phase. The main effects of fluoride can be attributed to the maintenance of constant fluoride levels in the biofilm. Overall, fluoride has multiple ways of reducing caries. It is believed that the most important of these methods is the remineralisation concept {{40 Oganessian,E. 2007}}, which requires a constant flow of fluoride. Bacterial enzyme inhibition plays a supplementary role when the concentration of fluoride is high which is achieved by topical fluoride applications and toothpastes (Murray, Rugg-Gunn Jenkins 1991). Who is at risk of decay? There are certain groups in the population who are at risk of decay and therefore, would benefit from the use of fluoridated dentifrices. These include patients with: Xerostomia, which may have resulted from the radiotherapy to the head or neck leading to salivary gland exposure. This leads to a decrease in both the resting and stimulated salivary flow rates. Xerostomia is defined as the complete absence of saliva or hyposalivation. Hyposalivation leads to decreased levels of calcium, phosphate and hydrogen bicarbonate ions. As a result, there is a longer demineralisation phase Sjà ¶grens syndrome- this is clinically defined as at least two of kerataoconjuctivitis sicca, Xerostomia(dry mouth) and rheumatoid arthritis or another connective tissue disease {{62 Newbrun,E. 1996}} A high incidence of caries in their primary dentition Hypersensitivity Root caries Removable orthodontic appliances and partial dentures A poor diet and those who regularly snack on fermentable carbohydrates {{37 Evans,R.W. 2008}}. However, this risk has decreased due to better plaque control and increased fluoride exposure. Multiple restorations suggesting a high prevalence of caries Optimum fluoride concentration required for remineralisation Bjarnason and Finnbogason (1991) found that fluoride levels in dentifrices had no effect on the progression of enamel lesions detected radiographically. However, a higher fluoride concentration (1000ppm F-) led to reduction in caries initiation compared to a dentifrice with a lower fluoride concentration (250ppm F-) {{69 Bjarnason, S. 1991}}. It is ultimately difficult to decide the optimum fluoride concentration required for remineralisation as different areas of the mouth are more at risk of caries due to unique ecological factors. However, it was thought that lesion progression in enamel was slowed down only in patients with low caries activity whereas patients with high caries activity still experienced rapid progression (Hellwig, Lussi 2001). DMF Index The DMF index is a measure of caries activity in a population and changes in the DMF index can be used to highlight the protective effects of the fluoride toothpastes and varnishes (Kidd 2005). D: decayed teeth with untreated carious lesions M: missing teeth (extracted teeth) F: filled teeth DMFT denotes decayed, missing and filled teeth DMFS denotes decayed, missing and filled surfaces in permanent teeth and therefore, the number of surfaces attacked on each tooth are accounted for. There are similar indices for deciduous tooth, which are the defs and deft scores. The e represents extracted teeth to differentiate(Johansen et al. 1987) between natural loss of teeth through exfoliation. Burt in 1998 suggested that greater emphasis has to be placed on the assessment and early diagnosis of caries {{77 Burt, B.A. 1998}}. This has been backed up by cohort studies {{83 Johansen, E. 1987}} (Axelsson, Lindhe Nystrom 1991), which found that the use of preventive strategies (fluoride application) resulted in a substantial reduction in lesion development and progression. Fluoride varnishes What is fluoride varnish? Fluoride varnish was first developed in New York in 1968 by Heuser and Schmidt in the form of sodium fluoride and was marketed under the name Duraphat. The Duraphat varnish contains 22,600 parts per million of fluoride (ppm Fˆ°) as shown in figure 2. In the 1970s, there was a switch from sodium fluoride to difluorsilane which was marketed under the name Fluor Protector (7000ppm Fˆ°) in Germany {{42 Azarpazhooh,A. 2008}}. Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration(%) Duraphat Sodium Fluoride 22,600 2.26 Duraflor Sodium Fluoride 22,600 2.26 Fluor protector Difluorsilane 7,000 0.70 Fig 2: The table above shows the fluoride varnishes that are most commonly used. Other types of fluoride varnishes include: Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration (%) Lawefluor Sodium Fluoride 22,600 2.2 Bifluorid Sodium and Calcium Fluoride 56,300 5.6 Fig 3: The table above shows other fluoride varnishes which are available but are less commonly used {{24 Davies,G.M. 2008}}. Most fluoride varnishes contain fluoride in an alcoholic solution of natural tree resin. The main advantage of the varnish is that the resin base is very adherent to the tooth prolonging contact time between the fluoride and enamel {{26 Miller,E.K. et al 2008}}. Varnishes are easy to apply and relatively safe regardless of the high fluoride concentration as the amount of varnish applied to one child is only 0.5 ml on average (Ripa 1990; Petersson 1993). Varnishes are slow-releasing reservoirs of fluoride preventing immediate release of fluoride after application (Ogaard 1994). As a result, they are most effective at protecting against primary caries. The food and drug administration centre in America has not yet accepted fluoride varnish as an anti-caries agent but considered it as a liner/desensitising agent (Mason 2005). There is some debate as to the amount of fluoride taken up by the tooth surfaces. It was found that approximately half of the fluoride taken up by sound surfaces from Fluor Protector varnish was lost after 6 months suggesting that the large amount of fluoride taken up after one week does not bind permanently to enamel and that the effects of fluoride are more short term. There has also been a debate over whether fluoride varnish should be applied to wet or dry surfaces. Koch et al found that the fluoride uptake was much greater when the varnish was applied to dry tooth surfaces (Koch, Hakeberg Petersson 1988). Fluoride varnishes can be applied professionally up to two to four times a year. Marinho et al in 2002 investigated the effectiveness of fluoride varnish in preventing dental caries in children compared to a placebo or no treatment. Over 2700 systemically healthy children aged 16 or less received fluoride varnish containing 22,600ppm sodium fluoride. There was a large caries inhibiting effect on both permanent and deciduous dentition. However, the confidence intervals were relatively wide and the variation among the results was substantial. The success of the treatment may have been over estimated, as the results of the few trials may not have been representative. As a result, it is important to carry out more trials before a definite statement can be made of the effects of the fluoride varnish (Marinho 2002). In addition, more information is required on the scale of the fluoride effect and the adverse effects of fluoride. Effect on the DMFT/dmft Primary Dentition There was a 33% decrease in the decayed, missing and filled surfaces (Marinho 2002). A two year randomised clinical trial carried out on children with a mean age of 1.8 years, found that the application of fluoride varnish once, twice and three times a year reduced the mean dmfs by 53%, 58% and 93% respectively {{67 Davies,G.M. 2009}}. This highlights the importance of frequent varnish application. (Petersson, Twetman Pakhomov 1998)Petersson et al. in 1998 found a 19% and 25% reduction in the increment of approximal caries in children with a moderate or high caries risk respectively. This shows that children with a high caries risk benefit the most from the application of fluoride varnishes (Zimmer 2001). Ages 0-3 Weintraub and colleagues carried out a two year randomised controlled trial on 376 children aged between 6-44 months (Weintraub et al. 2006). The children were split into three groups: Those who received counselling Those who received counselling and the annual application of Duraphat Those who received counselling and the twice yearly application at six monthly intervals The number of lesions only increased in children who received counselling alone highlighting the protective effects of the varnish. Those children who received no varnish application were twice as likely of developing decay as those who received the annual application of fluoride. As the frequency of fluoride varnish application increased, the number of carious lesions decreased. One drawback of this trial was that simultaneous counselling and varnish application led to some ambiguity as to whether the effects were due to varnish application or counselling although fluoride application was seen to play a key role. Ages 3-6 According to the Cochrane Review, there was an overall 38% reduction in the DMFS/dmfs (Marinho 2002). A two year randomised study of 1,275 children in Canada aged between 6 months and 5 years found that twice-yearly application of Durafluor led to an 18.3% reduction in the dmfs increment (Lawrence et al. 2006). Mixed dentition There was on average a 46% decrease in dmfs. The fluoride varnish was an effective preventive measure for partially erupted permanent molars. Equally, patients who are insufficiently co-operative benefit from fluoride varnish application (Marinho 2002). Permanent dentition A randomised clinical trial used to examine the impact of fluoride varnish on the incidence of approximal caries, detected radiographically in 13 year olds over a three year period, found that the varnish applied monthly and twice a year reduced caries by 76% and 57% respectively again highlighting the importance of frequent fluoride application{{67 Davies,G.M. 2009}}. The caries reduction in permanent teeth shown in the Cochrane review of trials was similar to that achieved in a metaanalysis carried out by Helfenstein in 1994 when Duraphat was applied 2 times a year in children aged 9-15 years (Helfenstein, Steiner 1994). There was a 38% reduction in the caries. It is likely that most of the participants benefited from the use of a fluoridated dentifrice as the majority of the studies were carried out in Scandinavian countries between 1973 and 1987. However, as both the Cochrane review and the Helfenstien study were carried out involving a different selection criteria, it is debatab le as to whether the results from both these trials can be compared. In conclusion, application of fluoride varnish two to four times a year on both permanent and deciduous teeth is associated with a reduction in the caries increment (Marinho 2002). The effect of fluoride varnish according to different caries risks Mà ¶berg Skold carried out a trial which involved the application of fluoride varnish to approximal caries in adolescents living in different caries risk areas. The trial involved 758 students aged between 13 to16 years old. The large sample size meant that the results of this study were representative. This is because as the sample size increases, the variability of the results decreases. This means that the results have a greater statistical power and smaller confidence intervals. Fig 4: (Azarpazhooh, Main 2008) The figure above shows the groups which were chosen according to their caries risk and whether they had any fluoride in their tap water. Duraphat was applied to the approximal surfaces from the distal surface of the canines to the mesial surface of the second molars. Each group had different intervals of application shown in the figure below: Group No. of participants Frequency of Duraphat application One 190 Twice yearly in six-monthly intervals ( 6 times in 3 years) Two 186 Three times a year with a one week period each year(9 times in 3 years) Three 201 Eight times a year during school terms with one month intervals ( 24 times in 3 years) Four(Control) 181 No application Fig 5: (Azarpazhooh, Main 2008) The frequency of Duraphat application The results from this trial show that the biggest difference was between group one and the control group in high caries risk area (Gà ¶teborg). However, there was no significant difference between the groups regarding filled approximal lesions and approximal enamel lesions. There was a greater incidence of caries in the control group in comparison to the fluoride varnish groups in all risk areas highlighting the protective effects of the fluoride varnish (Mà ¶berg Skold et al. 2005). Overall, it was found that the school based monthly application of fluoride varnish is the best method of preventing approximal caries in areas of medium and high caries risk (Mà ¶berg Skold et al. 2005). School based prevention programmes A cluster randomised trial was carried out by M.C Hardman and colleagues involving 2,091 school children living in a non-fluoridated area. One group of students (1,025 students) received the twice-yearly application of Colgate Duraphat varnish whilst the other group (1,066 students) served as a control. This study found that the twice-yearly application of fluoride varnish did not lead to a reduction in caries in children living in the community {{43 Hardman,M.C. 2007}}. This is contrary to what was found by Marinho and colleagues. They found that the biannual application of Duraphat in a school-based programme provided a caries inhibition of 38% in children aged 9-15 years (Marinho 2002). The study carried out by M.C Hardman and colleagues did not prove to be conclusive as the level of consent in the community was low. Approximately 110 students were lost during the study. The control group had lower caries levels than anticipated and therefore, it was difficult to tell the true eff ect of fluoride. In addition, the application of varnish was carried out under sub-optimal conditions (teeth could not be cleaned prior to application and the consumption of food and drink after application could not be controlled), which could have resulted in less profound effects. In conclusion, it was found that this type of fluoride varnish intervention is not effective in the prevention of caries in the public {{43 Hardman,M.C. 2007}}. A similar study was carried in a small town located in the American Southwest on children attending a head start nursery using Duraflor as the varnish of choice. The trial began in the head start class of 2002. Duraflor was applied during well child visits every 9, 12, 15, 18, 24 and 30 months. The class of 2003 had no fluoride application and therefore, served as the control. The mean age was 4.40 years and approximately 168 males and 189 females took part. The results showed that children who received no treatment had a mean dmfs of 23.6 with a 95% confidence interval. Those children who received 1-3 treatments had a similar dmfs to those with no treatment. Only those children who had 4 to 5 treatments showed a reduction in dmfs again suggesting the importance of frequent application. However, this study was an observational study not a randomised study and therefore, the reliability of the results can be questioned. In addition, no attempt was made to determine whether the childre n who received four or more applications of fluoride varnish differed from the other children in terms of diet and oral hygiene history {{58 Holve,S. 2008}}.. The use of fluoride varnish in inhibiting secondary carious lesions As mentioned earlier, secondary caries forms at the margins of restorations. Larger amounts of fluoride varnish may be trapped in the gap formed between the restoration and the cavity wall. This may serve as a slow releasing reservoir of fluoride, which could also provide a physical barrier against wall dissolution. In a study carried out by M. Fontana in 1996, two experiments were carried out. Experiment one involved the application of Duraflor. Experiment two involved the application of Duraphat a year after the application of Duraflor. The effects of fluoride varnish on secondary caries remineralisation and lesion progression were measured. The varnish was applied to dry tooth surfaces and rinsing after fluoride application was prevented to enhance the remineralisation potential. The varnish was applied for 24 hours to prolong the contact time between the varnish and the tooth surface. The results from these two experiments showed that fluoride application slowed down lesion progression around both amalgam and composite restorations {{48 Fontana, M. 2002}}. The placebo varnish slowed down lesion progression to a lesser extent than the fluoride varnish suggesting that the effects may not only be attributed to the fluoride in the varnish. These results matched those in a previous study carried out by Hellwig et al. in 1993. They examined the effect of Duraphat varnish on artificially created primary carious lesions and found that fluoride varnish led to remineralisation in the outer layers of enamel {{78 Hellwig, E.K. 1993}}. This slowed down lesion progression. Seppa suggested in 1988 that the benefits of fluoride varnish were attributed to their ability to enhance remineralisation of primary caries rather than their ability to increase the fluoride content of the tooth surface. This is contrary to what was previously thought that the effects of topical fluoride were due to their ability to maintain high levels of fluoride on the surface of the tooth. Seppa also found that the efficacy of the fluoride varnishes was dependent on the number of applications rather than the concentration of fluoride {{79 Seppà ¤, L. 1988}}. This backs up the results found by Marinho et al that showed that the more frequent the applicati on, the lower the incidence of new caries or the greater the decrease in mean dmfs/DMFS. Fluoride toothpaste What is fluoride toothpaste? Fluoride toothpaste is the most widely used method of fluoride application in the population due to its ease of use. Fluoride toothpastes can be incorporated into community and school based prevention programmes. Most oral health care workers recommend brushing twice a day, once just before going to bed, as this is when saliva flow is at its lowest and once at another time of day{{68 Davies,R.M. 2003}}. They recommend spitting out the toothpaste after use rather than rinsing as this dilutes the fluoride concentration in the oral cavity as previously mentioned. The widespread use of fluoride toothpastes had made it more difficult to distinguish whether a reduction in caries is due to mechanical plaque removal or due to the incorporation of fluoride. Before the widespread use of fluoride toothpastes, the importance of fluoride was illustrated in a three-year study. This study involved two groups of children aged 9 to 11 years who had benefited from supervised brushing either with or without fluoride toothpaste. Both groups showed a reduction in plaque and gingivitis but a significant reduction in caries was only seen in the group which used fluoridated toothpastes (Davies et al. 2003). A typical toothpaste contains abrasives such as calcium carbonates, which help to remove surface debris, and stains on the tooth surface. Most toothpastes contain fluoride (added to toothpastes in the 1970s) to make the tooth more resistant to acid attack and is one of the most recognised agents in toothpastes. Stannous fluoride (also known as tin fluoride) was the first fluoride to be used due to its compatibility with the abrasive, calcium phosphate. Sodium fluoride could not be used at first as the calcium in the abrasive renders it ineffective and therefore, is not compatible. Sodium Monofluorophosphate was next used as it was compatible with the abrasives used with it. Sodium Fluoride could only be used when hydrated silica and sodium bicarbonate became the abrasive of choice. Studies have shown that the sodium bicarbonate-sodium fluoride combination lead to a caries reduction of one surface per child over two years (Murray, Rugg-Gunn Jenkins 1991). Fluorides have been shown to work better in combination with detergents such as sodium lauryl sulphates, which aid the remineralisation process and create foaming whilst brushing. Toothpastes contain humectants such as glycerol, which prevent the loss of water in the toothpaste. To provide taste, saccharin and other sweeteners are added. To stabilise the toothpaste, thickening agents such as seaweed colloids are included to ensure that the toothpaste stays on the toothbrush when it is applied. The use of fluoride toothpastes in clinical trials The Cochrane review of trials found that children who used fluoridated toothpaste had fewer decayed,missing and filled permanent teeth after three years. Brushing twice a day helps to increase the benefit of fluoride (Marinho et al. 2003 England). Researchers believe that the effects of fluoridated toothpastes are underestimated in two to three year trials due to the life long used of fluoride. They also found that the use of fluoride toothpastes in areas of fluoridated water increased the protective effects. The normal concentration of fluoride in toothpastes is between 1000 and 1100 parts per million (ppm Fˆ°). Toothpastes with higher fluoride concentrations (1500ppm) and lower fluoride concentrations (500ppm) are available in many countries. Toothpastes containing higher fluoride concentrations offer greater protection against caries (Stephen 1988; OMullane 1997). Since the 1940s, more than a 100 clinical trials have been carried out and by the late 1970s, the protective effects of fluoride toothpastes were greatly accepted. As a result, many clinical trials could not have a control, as the removal of fluoride toothpaste for the trial was considered unethical. Therefore, the effectiveness of different concentrations of fluoride toothpastes have not been investigated extensively in placebo-controlled trails. The guidelines of caries trials have since been changed in order to combat this problem, by increasing the sample size so that the measurement error could be reduced (Marinho et al. 2003 England). Children or adolescents aged sixteen or less were chosen to take part in the study carried out by Marinho et al. To assess the effect of the fluoride toothpaste, the caries increment was measured as a change in the value of the DMFS Index, in all permanent teeth erupted at the start and erupting over the course of the study. Evidence from this study suggested that the use of fluoride toothpastes leads to a 24% decrease in dmfs. The confidence intervals for this reduction were 21-28%. This means that 1.6 children need to brush with fluoride toothpaste to prevent one decayed, missing or filled tooth surface in a population where the caries increment is 2.6 DMFS per year. Where the caries increment was lower (1.1 DMFS per year), 3.7 children needed to use a fluoride toothpaste in order to avoid one decayed, missing or filled tooth surface(Marinho et al. 2003 England). There was also a substantial reduction in caries increment (37%) of deciduous teeth in a trial carried out on 2008 children aged 6 to 9 years. Another aim of the Cochrane review (Marinho et al. 2003 England) was to establish whether there was any relationship between the caries-preventive effects of fluoride toothpaste and the initial level of caries, previous exposure to fluoride and the frequency of fluoride toothpaste use on the prevented fraction. The prevented fraction (PF) is the proportion of disease occurrence in a population averted due to a protective risk factor or public health intervention (Gargiullo, Rothenberg Wilson 1995). The prevented fraction was measured as the diffe

How The Internet Is Used To Book Flights Tourism Essay

How The Internet Is Used To Book Flights Tourism Essay It is fair to say that internet has revolutionized the way we buy airline tickets or choose our holidays. The internet is responsible for a major shift in airline and travel industry. This was not the same some years before as when the internet was in its infancy, the main problem of booking airline ticket online was to find out what you are looking for and also having the confidence to buy it online due to the money involved in it. Booking tickets online is not something that is uncommon these days. But nowadays it has become like a second nature for large number of people to open up the search engines and purchase all kind of things from electronic items, foods to air tickets. David J http://EzineArticles.com/?expert=David_J_Cook The success of internet giants like Amazon and eBay with its secured payment systems like PayPal has given confidence to the buyers to purchase things online and today almost everyone knows the advantages and benefits of buying flight tickets online for the domestic as well as international travel. Although its not very easy task but the airline and travel agent websites has made internet travel booking so simple that even a person with little computer knowledge can purchase cheap tickets online and enjoy benefits. Quick booking facilities and best profitable bargains can be enjoyed at the ease of sitting at home rather than standing in queues for hours on airline ticket counters. The online buyer can easily compare the airfares of different airlines and can choose the best bargain and online booking is the best solution to get cheap flights tickets and also the best travel solution for those travelers who cannot afford to spend too much on traveling. David J http://EzineArticles.com /?expert=David_J_Cook And cheap tickets are not hard to find now, its easily available online through the convenience of doing it at home rather than visiting a travel agent or airline office to book it and within few clicks tickets can be booked using your credit or debit card and within few days the e-ticket is delivered in your mailbox and at your correspondence address. Today there are lots of other websites other than airline official websites where the travelers can book their tickets and these websites are designed in such a way that a traveler has to just specify the date of travel and destination and the search engine within that websites pick up the best deals and the discounted offers from any airline.

The Language of Male Supremacy in She and The Sign of Four Essay

The Language of Male Supremacy in She and The Sign of Four These days we have to be extremely careful when we write or speak.   In fact, at times it seems as if we must communicate as if tip toeing through a veritable minefield of the dangerous misinterpretations of our words.   Since many words and phrases can be construed or misconstrued as offensive, there is a heightened sensitivity to the use of language.   This is not necessarily a bad thing.   We certainly need to live in world where all people are treated with dignity and respect, and our use of language should reflect this ideal.   Most of us would not intentionally offend a person from a different race, culture, or creed, but the problem today is that there is such a subsurface tension that rage occasionally erupts over anything that even remotely resembles the offensive.   Where does this social extremism that condemns even ambiguous statements come from?   Things were not always this way.   If we were to look deeper into the history of the English language, we would typically find outlandish words and phrases that debased women and members of other cultures.   These expressions may not necessarily have been malicious in spirit in all instances, but they were certainly demeaning and ranged from the subtle to the intentional.   Certainly, some of the phrases that were commonly printed then would be socially unacceptable to print today.   For example, any representative sample of late Victorian literature will reveal misogynistic and racist remarks by contemporary standards. In fairness to the Victorians, the world was going through a rapid state of change then, and England was leading the way.   Part of the motivation behind the imperialistic ende... ...winism dramatically changed the way many people thought then, our modern ideas of cultural diversity and gender egalitarianism have changed the way many people think today.   Our modern language clearly reflects this change.   We have come a long way in disregarding boldly offensive descriptions, to questioning the propriety of statements such as "You people."   Some people have eager ears that are always ready to latch onto the next faux pas and have clenched fists that are ready to gaff their next victim.   Therefore, a masked tension remains, but on a lighter note, the positive force that guides our present evolving world in which we are conscientiously laboring to temper our language with human dignity balances this tension.   Yet, our language can only be truly dignified to the degree to which it preserves the dignity of all of whom it dares to describe.

By the end of 18th century, with the industrialization of steel and glass, architecture began to take on a different role in the society. Architecture was no longer about building structures for an individual, but was about concerning with beauty, style, and aesthetics within the technology of space (Conway 8). The idea that building plus art equals architecture was no longer valid, as the equation undermined the true meaning of architecture. In Understanding Architecture, Hazel Conway states, â€Å"the allocation of living space is economically, socially, and culturally determined† (6), when discussing the purpose of architecture. This means that the surrounding environment of the building, also referred to as built space, is often intertwined with social relationships. Built space can be defined as the philosophical way of referring to architecture. To a certain extent, the architecture becomes about the philosophical investigation into built space, rather than establishing a single building. Through the examples of artists and architectures, such as Rachel Whiteread, Robert Smithson, Meis Van Der Rohe, and Gordon Matta-Clark, this paper will demonstrate how art pushes architecture into critical examination of built space. In doing so, it will be evident that artists and architecture define sculpture, object, prototype, installation, network, building, assemblage, and/or habitat differently. An artist who dealt with technologies of built space is Rachel Whiteread. The core concepts of Whiteread’s work includes, playing with negative space and scale, and focusing on line and form. In the piece called Judenplatz Holocaust Memorial a.k.a. Nameless Library, Whiteread uses sculpture to represent what is not there, the empty space. By... ...about recreating scale. When a person sees this piece from an airplane view or on a balcony, he or she will experience the massive quantity of the artificial nature that has been produced. However, when a person sees this piece from a ground level, the 14,000 translucent, white boxes just becomes a boring, everyday object. Depending on the location of the viewer’s presence, the piece symbolizes a different meaning. This piece is similar to the works of Tara Donavon, whose core concepts include playing with scale and working with multiplicity. She is known to use everyday household materials to create large-scale installations and sculptures. In the piece Styrofoam Cup Sculpture, Donavon glues countless amount of Styrofoam cups together to create a synthetic material that challenges the viewer’s to have second thoughts about the basic functions of everyday material.

The Change in Scrooge’s Character :: A Christmas Carol Charles Dickens Essays

The Change in Scrooge’s Character How does dickens show the change in scrooge’s character in ‘A Christmas Carol’, look closely at the language used and how this influences the reader In 1843 Charles dickens wrote ‘A Christmas Carol’ partly to make people aware of the terrible conditions of the children of the poor. In 1843 he visited the field lane ragged school and was appalled by what he saw there/ ragged schools catered for the very poorest, hungry children who roamed the streets, trying to teach them the basic skills of reading and writing. He had also been shocked by a parliamentary report by the children’s employment commission. Dickens was the most popular novelist of the day and he soon realized that far more people would take notice of the terrible conditions of the poor if he wrote about them in a story. ‘A Christmas carol’ was published on 17th December 1843 and by the 24th he had sold 6,000 copies. Dickens called it a most prodigious success., the greatest, I think, have ever achieved. ‘A Christmas carol’ is still widely read today and appears in many versions including illustrated re-telling of the story for young children. Hardly a Christmas goes by without a version of ‘A Christmas carol’ appearing on TV in one form or another. The name of the main character, scrooge, has come into general use in the English language meaning ‘a miserly or mean person’. In ‘A Christmas carol’ Dickens shows scrooge as an evil, nasty man by using a long list of adjectives, he’s described with this sentence â€Å"Oh! But he was a tight fisted hand at the grindstone, scrooge! A squeezing, wrenching, grasping, scraping, clutching, covetous old sinner! Hard and sharp as flint, from which no steel had ever struck out generous fire; secret, and self-contained, and as solitary as an oyster† Another way to show this is the way he talks to people, e.g. when his nephew invites him to his Christmas party but he turns him down and calls Christmas a ‘Humbug!’ and even worse, when 2 charity workers ask him for a donation for the poor children, he says send them to the work houses, if they would rather die they better do it, and decrease the surplus population. This shows how much of a cold hearted, covetous sinner he is. Dickens makes us feel like he’s an evil man, he’s selfish and says he’d rather the children die than donate his money to charity. When the ghost of Marley visited scrooge in the night, he was shocked, he first saw Marley’s face as the doorknob, then he was frightened further when the ghost of Marley opened the door from the outside when

Overview Of The Los Angeles International Airport Engineering Essay

Los Angeles International Airport has been one of the busiest airdromes in the universe, making figure three countrywide and 7th worldwide in the twelvemonth 2009. LAX serves the Los Angeles Metropolitan Area every bit good as the Greater Los Angeles Ares. The Greater Los Angles Area is made up of five counties in Southern California- Los Angeles County, Orange County, San Bernardino County, Riverside County, and Ventura Country. With a combined population of 17.6 million, Los Angeles Area is home to the 2nd largest population country in the United States, merely behind the New York metropolitan country. Peoples from over 140 states have been settling here. As a consequence, Los Angeles embraces one of the most diverse civilizations in the universe. ( Los Angeles, California ) International trade, amusement industry, fabrication, and engineering make up a important part of the metropolis ‘s economic system. Los Angeles is the headquarter for many of the Fortune 500 companies such as The Walt Disney Company, Hilton Hotels Group, Paramount Pictures, and Sony Pictures Entertainment. The LA Metropolitan Area is besides the state ‘s largest fabrication and technological centre and is good known for its new and radical innovations. Because of its premier location in the West seashore and the propinquity to Pacific Rim states, the ports of Los Angeles handled more tunnage of goods than any other port in the state. ( Los Angeles, California ) Tourism plays another major function in the regional economic system. Los Angeles is globally renowned for its amusement Parkss, shopping centres, museums, beaches, and nightlife. Millions of visitants flock here from all parts of the Earth to bask the warm conditions, breath-taking sceneries, diverse civilization, and a broad assortment of things the metropolis has to offer. In 2009, Disneyland entirely attracted 15 million visitants. ( Disneyland ( Anaheim ) )Brief HistoryThe airdrome ‘s history began in 1927 when the Los Angeles City Council planned to construct a municipal airdrome on a site which used to be a wheat field. Judge Frank D. Parent chose 640 estates of land on July 25, 1928, laid soil set downing strips, and designated the airdrome to general air power. This landing field was so given the name- Mines Field. The landing field opened in 1930 and became the official airdrome of Los Angeles. In the beginning, the metropolis leased the airdrome at $ 124,800 per twel vemonth for 50 old ages, but decided to buy the airdrome in 1937 for $ 2,240,000. ( LAX History ) During World War II, Mines Field converted to military operations. Commercial services did non get down until after the war in December 1946. When the airdrome expanded due west in early 1950s, it encountered a terrible job. The airdrome must spread out into Sepulveda Boulevard-a major roadway in the metropolis. The airdrome contrivers came up with an clever solution by delving a tunnel underneath the airdrome track, so auto traffic will non be affected by the enlargement. This sub-airport tunnel was the first of its sort any where in the universe. ( LAX History ) Before the morning of Jet Age, maestro contrivers of LAX called for a important airdrome update. Most of today ‘s airdrome substructure including the terminuss, taxi strips, control tower and tracks were built between the old ages of 1957 through 1965. The iconic Theme Building was the centrepiece of this awaited undertaking. The edifice was retro-futuristically designed into the form of a winging disk, and it hosts a rotating eating house. Walt Disney Imaginers installed particular consequence illuming onto the Theme Building in 1997, and the colourss can be adjusted to reflect particular occasions. Today, the Theme Building is place to the Encounter Restaurant. ( Los Angeles International Airport ) To expect for the addition in air travel during the 1984 Summer Olympics Games, the direction spent $ 700 million to spread out and update the airdrome. All terminuss were split into three degrees, with the top floor for going, in-between floor for fining and the bottom floor for geting. Planners besides built Tom Bradley International Terminal to manage turning international traffic demands. Terabit costs $ 123 million. The international terminus was named after Tom Bradley, the metropolis ‘s first African American city manager. In 1988 and 1989, LAX underwent a series of Reconstruction undertakings and betterments. Runway 24L-6R was wholly rebuilt. All bing tracks received touchdown visible radiations and center line. Many terminuss got more square footage, better fining countries along with more Gatess. Planners besides decided reconstruct Runways 24L/6R its and taxi strips to farther suit the larger wing spans of Boeing 747.Figure -LAXpectations streamerToday, LAX is undergoing an ambitious betterment plan called LAXpectations. The undertaking includes upgrading the Tom Bradley International Terminal, building a trade name new terminus, renovating the current cardinal terminal country, put ining track position visible radiations, and put ining a film editing border baggage testing system.( See Figure 1 ) The end of the multibillion betterment plan is to supply a better going experience for all riders while guaranting the highest safety criterions. In mid-2008, the airdrome finished retracing Runway 7R/25 to forestall track incursions and to suit following coevals Airbus A380s. The following few old ages will surely be the most exciting period in the history of the airdrome. More inside informations about the betterment plan will be discussed in ulterior subdivisions.Existing FacilitiesLos Angeles International Airport presently uses four near-parallel runways-6L/24R, 6R/24L, 7L/25R, and 7R/25L. They are 8,925 pess, 10,285 pess, 12,091 pess, and 11,096 pess in length, severally. Runways 6L/24R and 6R/24L are located on the north side of the terminuss ; while tracks 7L/25R and 7R/25L were built on the south side of the terminuss. With a breadth of 200 pess, 7R/25L is the widest of four tracks. The other three are all 150 pess in breadth. ILS and DME approach systems were standardized o n all four tracks. The airfield lift is 126 pess. Between the North and the south landing field stands the 277 pess tall, palm tree shaped air traffic control tower. The tower handles all clearance bringing, flight informations, and gate-hold places, while each of the four tracks is operated by local control and land accountants. ( Administration ) By and large talking, IFR aircrafts should hold a separation of three stat mis laterally and one 1000 pess vertically. One exclusion to this regulation is the coincident attack of the parallel tracks, which requires a separation of 4,300 pess. This is to forestall coincident attack at immediate tracks. The 4,300 pess of separation allows for two aircrafts to set down at the same clip on two non-immediate tracks, for illustration, on ILS 24L and ILS 25R. Pilots must hold the proper aircraft equipments including a transponder, and winging experiences to run at the airdrome. This is the general regulation under category Bravo, which all aircrafts receive radio detection and ranging separation. Pilots under Class B air space will be given a squawk codification. When nearing the airdrome, pilots are recommended to reach the tower at a distance 30 to forty stat mis, but the pilot must inform the accountant is he or she is unable to wing the attack. This is particularly the instance under low visibleness fortunes. ( Stearns ) Los Angeles International Airport uses nine rider terminuss, numbered 1 through 8, plus the primary international terminal-Tom Bradley International Terminal ( TBIT ) . Terminals were arranged in the form of the missive â€Å" U † . The terminal cringle starts at World Way Drive North, on the west side of South Sepulveda Blvd. Once come ining the airdrome, autos make a counterclockwise circle in the order around Terminals 1, 2, 3, Tom Bradley International Terminal, and so onto Terminals 4, 5, 6, 7, 8. All nine terminuss are split into three degrees. With the exclusion of Tom Bradley International Terminal, the eight terminuss uses the upper degree for goings, in-between degree for fining and lower degree for reachings. Tom Bradley International Terminal combines fining and going into in-between degree while using the top degree for eating houses. Just like the other eight terminuss, the lower degree of Tom Bradley is dedicated to geting riders. Two degrees of roadways allow autos and coachs to straight entree the fining degree and the arrival degree for the terminuss 1 through 8. Travelers can easy entree all degrees of the same terminus by stepss, escalators, or lifts. Dividing up the reachings and fining degrees help eases congestions for the auto traffic. Because nine terminuss do non complect, shuttle coachs provide the quickest manner for riders to go between terminuss. The lower degree accommodates ground transit such as cab, shared drive new waves, air hose birds connexions and coachs. Shuttle buses Michigans at each terminus about one time every 12 to fifteen proceedingss. Walking between terminuss is ever an option for reassigning riders ; nevertheless it can take more than 30 proceedingss to walk to the terminus located at the other side of the cringle. Most of the terminal substructure, including Terminal 2, 3, 4, 5, 6, and 7, were built back in the early 1960s, Terminal 1 and TBIT opened to the populace in 1984, and 1988, severally. ( LAX History ) Even though LAX uses nine independent terminuss, gate Numberss do non reiterate. ( See Table 1 ) In other words, every gate figure is dedicated to a individual terminus. For illustration Terminal 1 uses Gatess 1 through 15, and Terminal 2 starts the gate count at gate 21 and goes up to gate 28. Terminal Number of Gates Gates 1 15 1-3, 4A-4B, 5-14 2 11 21-21B, 22-22B, 23, 24-24B, 25-28. 3 13 30, 31A, 31B, 32, 33A, 33B, 34-36, 37A, 37B, 38, 39 4 14 40, 41, 42A, 42B, 43, 44 45, 46A, 46B, 47A, 47B, 48A, 48B, 49B 5 14 50B, 51A-51B, 52A-52B, 53A-53B, 54A-54B, 55A, 56, 57, 58A, 59 6 14 60, 61, 62-62A, 63-66, 67A-67B, 68A-68B, 69A-69B 7 11 70A-70B, 71A-71B, 72-74, 75A-75B, 76, 77 8 9 80-88 Terabit 12 101-106, 119-123Table 1-Terminals and GatesTenants and UsersMore than 60 air hoses have regular flight services to and from Los Angeles International Airport. Together, these air hoses connects rider with 87 domestic and 69 international metropoliss. With 15.1 per centum in airdrome rider traffic, American Airlines is largest air hose in operating at LAX. United Airlines and Southwest Airlines besides make up a important rider count at 14.83 and 12.44 per centum, severally. Australian airliner Qantas is the largest foreign operator, with 2 per centum of entire riders. ( LAWA ) The flights between operated by Singapore Airlines between LAX and Singapore is the 2nd longest non-stop flight between any two airdromes in the universe, merely puting behind the Newark-Singapore path. Flight SQ38 from Singapore Changi Airport to Los Angeles International takes 16 hours while winging great circle path of 9,134 stat mis. The return flight SQ37 from Los Angeles to Singapore is an even longer flight at 18 hours and 10 proceedingss. Flight SQ37 covers a distance of 8,771 stat mis. Both extremist long flights utilize Airbus A340-500. ( Non-Stop Flight ) Since the Los Angeles Area is home to the largest Asiatic population country in the state, LAX airdrome has most flights to Asia than any other airdromes in the state. The airdrome is frequently referred to as the â€Å" Gate Way to Asia † . The growing in traffic between LAX and Asiatic metropoliss has been turning significantly of all time since the TBIT was built in the 1980s. In fact, LAX entirely has six Chinese bearers in operation. Cross-Pacific flights derive a big part of income for the air hoses because burden factors average above 80 per centum ( LAX: Gateway to Asia ) Landmark Aviation is the airdrome ‘s concern activity FBO ; it is in operation 24 hours a twenty-four hours, 7 yearss a hebdomad. The installation is located South of 7R/25L and has the capableness to function all sizes of concern aircrafts up to the size of Boeing 767. Everyday services include valet parking, conference room, VIP room, pilot ‘s sofa, flight planning room, aircraft care. ( Landmark Aviation Airport Services ) LAX is home base of the Coast Guard Air Station Los Angeles. Three HH-65 Dolphinfishs are based at the airdrome. Mission of the air station includes hunt and deliverance, navigation support, and general military operations. The station works closely with the lifesavers throughout the country in helping drop and H2O deliverance.Airport ActivityIn 2009, the airdrome recorded 56,520,843 enplanement riders, the lowest figure in three old ages. The largest growing during that period occurred in twelvemonth 2004 when Numberss grew 10.61 % over the old twelvemonth. After the twelvemonth 2004, enplanement growing slows down and even goes into diminution in the past three old ages. . Airport has been turning steadily all the manner up to the twelvemonth 2000 when the enplanement riders reached 67,303,182, but the airdrome activity plummeted significantly in twelvemonth 2001, and reached the low point of 54,982,838 enplanements in twelvemonth 2003. 2001 Terrorist Attacks had evidently caused t he diminution in the air travel industry. Despite the initial tendency of recovery after twelvemonth 2001, the figure of enplaned riders is still significantly below pre-9/11 degrees. ( See Figure 3 Below ) ( Statistics Volume of Air Traffic ) Figure -Enplanement 2004-2009 ( Statistic Ten Year Summary Passengers ) Like most other airdromes, LAX rider enplanement is non uniformly distributed throughout the twelvemonth. The monthly norm of twelvemonth 2009, derived by spliting one-year enplanement by 12, is 4,710,070. The standard divergence is 490,272 ; hence the Numberss are still comparatively close to its mean. Enplanement activity spiked in the month of July with more than 6 million riders, and it reached the lowest point in February with merely over 4.3 million riders. ( See Figure 4 below ) Planners must be cautious about monthly norms when it comes to capacity related determinations because non merely activity have peak month, but besides peak twenty-four hours an even peak hr. An efficient airdrome must be able to manage traffic when activity reaches far beyond mean enplanement. For this ground, monthly norm has limited value for airdrome contrivers. Figure -Year 2009 Monthly Enplanement ( Statistics Volume of Air Traffic ) Top 5 busiest air hoses in falling orders are American Airlines, United Airlines, Southwest Airlines, Delta Airlines, and Alaska Airlines. The top five air hoses fly largely domestic finishs. Alaska Airlines carries the most international riders among the top five air hoses, while Southwest Airlines operates entirely within U.S. boundary lines. ( LAWA ) Aircraft operations at Los Angeles International Airport in twelvemonth 2009 are made up of 68.8 per centum air bearer, 28.5 per centum air cab, 2.5 per centum general air power, and less than.4 percent military. ( See Figure 5 below ) ( Statistics Volume of Air Traffic ) The standard divergence of the entire operation for the past five twelvemonth is merely over 20,000. From the operation statistics, it is clear that LAX operate chiefly air bearers and air cab since these two class makes up 97 per centum of airdrome activity Operations for the past twelvemonth declined drastically. Number of operations decreased from 622,506 in 2008 to 544,833 in 2009. It is deserving observing that air cab operation declined by about 50 per centum from 150,561 in 2008 to 86,919 in 2009. Despite the heavy operation at LAX, merely six aircrafts are based at the airdrome. Four of which are military chopper, and the other two are jets. This figure is improbably low for the airdrome the graduated table of LAX. In comparing, the non-commercial Van Nuys Airport ( VNY ) in San Fernando Valley has 709 based aircrafts.

LAX is the primary public airdrome in the Los Ang eles Area. LA/Ontario and LA/Palmdale operates commercial service at a much smaller graduated tables, while Van Nuys handles the busiest general air power traffic in the universe.

The mission of this board is to do policies that will profit the airdrome riders and the community. Seven members form the board of commissioner, each functioning five twelvemonth footings. The board members are appointed by city manager and approved by the metropolis advocate ; they are an elect squad of concern professionals, community leaders, urban contrivers, lawyers, and bookmans. Board ‘s docket and studies are often published for the populace on the Los Angeles World Airport web site. Jeff Fitch is the current director, deputy executive of operations and care of Los Angeles World Airports. Duties of airdrome director include security, safety, terminal and landside operations. Having the background as the Commander of Operations at Grand Forks Air Force Base and general director of terminal operations at Seattle Tacoma International Airport, Mr. Fitch gained extended experience in airdrome direction in both civilian and military sectors. ( L.A. World Airports )Airport IssuesIn recent old ages, incursion incidents and outdating terminal substructures are the two chief issues endangering the hereafter developments at Los Angeles International Airport. This subdivision will discourse the significance behind those issues, and their solutions.Runway IncursionsLAX is notoriously known for its hapless track safety records. From twelvemonth 2000 to 2003, LAX has the highest figure of runway incursions of all commercial airdromes in the state. The airdrome experienced 16 in cursions in twelvemonth 2006 through 2007, four of which are classified as serious. The closest call occurred on August 16, 2007, between Westjet Flight 900 and Northwest Flight 180. After set downing on track 24R, Westjet Flight 900 was trying to traverse the track 24L while Northwest Flight 180 is in the center of takeoff axial rotation. The two aircraft came within 40 pess. Runway incursions must be reduced and eliminated because it is likely that a ruinous clang will happen. ( Air Safety Week, 2007 ) Although human mistakes due to miscommunications were the chief cause for most of the track incursion incidents, the blemished design of tracks besides played a major function. All aircrafts set downing at the two outer most tracks, 6L/24R and 7R/25L, must traverse the immediate analogue tracks to entree the chief terminuss. To farther complicate this issue, parallel tracks were laid out excessively closely, so aircrafts go outing the outer runways merely have limited infinite to halt before traversing into the nearby track. ( Air Safety Week ) Under the guidelines of the Federal Aviation Administration ‘s Runway Safety Program, legion options were reviewed by the maestro contrivers. Ultimately, a halfway taxi strip became the most plausible solution. Several undertakings are specifically designed to cut down the likeliness of future track incursions, and to better the overall safety of the landing field. At the halfway piece of the major renovation undertaking is the $ 333 million dollar South Airfield Improvement Program ( SAIP ) . Approximately $ 250 million were spent to relocate the track, and the other $ 85 million went to the new taxi strip undertaking. The support came from many beginnings including landing fees, Federal Airport Improvement Funds, airdrome operating gross, and airport capital betterment financess. The first measure of the South Airfield Improvement Program was to pulverize the track 25L/7R. Then an indistinguishable track 25L/7R was rebuilt 55 pess south of the old track. All track lighting, navigational AIDSs and other public-service corporations had to be relocated as the consequence of this resettlement. Next, a new taxi strip was constructed between the two parallel tracks. The new taxi strip gives more infinite for geting aircrafts on the outer track to taxi on until the aircrafts are given the authorization to traverse the interior track. The taxi strip will probably to cut down most types of track incursion instances ; moreover, it minimizes the taxiing clip for aircrafts. ( Los Angeles International Airport ) Besides the Southern Airfield Improvement, track position visible radiation is another state-of-the art engineering that helps forestall future incursions. These visible radiations warn the pilots when the track being crossed is in usage, so pilots are less likely to traverse an active track. The track position visible radiation undertaking is a joint attempt between the FAA and the Los Angeles World Airport Authority ; the entire cost is estimated at $ 7.7 million.Facility Improvements and ExpansionsSince most of the terminus installations were built prior to 1980s, airdrome is get downing to demo marks of restraint due to its skyrocket growing. Terminals were non designed to manage today ‘s airdrome activity when they were built in the sixtiess ; really few Gatess can even suit Boeing 747s. Furthermore, the E, North, and south sides of the airdrome are heavy residential vicinities, so it is hard for the airdrome to spread out. As the consequence of the airdrome ‘s ain s uccess, LAX was get downing to lose international fight. From twelvemonth 2000 through 2006, LAX had lost 12 % of international riders. Some foreign bearers avoids LAX merely because of its out-of-date terminuss, alternatively, they choose more modern airdromes such as San Francisco International. ( Oldham ) Losing riders is non merely job for the airdrome, but the whole country of Southern California suffers as the consequence. Since the airdrome is one of the economic power house in the country, losing competiveness may take to occupation cuts and decreased foreign trade. In other words, it will both straight and indirectly affect the overall economic well being of Southern California. Because the Tom Bradley International Terminal was built more than two decennaries ago, a renovation is necessary to run into the of all time increasing demands of future rider traffic. TBIT is presently undergoing a major face lift to do many facets of international air going more comfy and efficient. Ticketing countries, in-migration lines, going countries, and more efficient HVAC systems are merely some of the targeted betterment countries. More boarding Gatess will be modified to manage larger jets like Boeing 747s and Airbus A380s. The new luggage showing system frees up the infinite in the cheque in country by traveling sensing equipment to behind the air hose counters. New luggage testing units besides reduces the congestion in the check-in countries and the delay clip for riders. LAWA contracted Siemens Logistics for the installing of modern digital shows that will break direct the flow of riders. The entire cost of TBIT betterment is estimated at $ 723.5 million. Terminals 1 through 8 will besides acquire a security system upgrade similar to the 1 at TBIT. Explosion sensing systems, detonation hint Stationss, and closed circuit telecastings are being integrated into the bing security system. This undertaking costs $ 577 million. In add-on to the security systems, all terminuss will have minor modern-day touches. ( Los Angeles International Airport ) Even though the freshly developed TBIT will pull more riders to LAX, it is non sufficient to manage the addition in international rider activity. To accommodate to the growing in new coevals superjumbo jets, the program to construct a trade name new terminus, Midfield Satellite Concourse, was passed by the airdrome council. The new multitude will be capable of managing jets the size of Airbus A380s. An belowground tunnel allows people to entree the new multitude which is about one-fourth mile West of the current terminus composite, and it will use a people mover system. Ten Gatess and an estimated 500,000 to 600,000 square footage of terminal infinite will be added on at a cost of $ 1.2 million. The new multitude undertaking is scheduled to finish in 2012. Airport council besides called for an enlargement on the current TBIT Terminal. Additional Gatess will be added on the west side of TBIT to manage increasing broad organic structure jets. ( Hymon )Personal Observations and Decision The worst record in runway incursions is surely non the acknowledgment any airdrome want to have. Even though we recognize that all human existences make errors, errors are merely unbearable in the air power industry. In response to the hapless safety records, maestro contrivers launched a series of undertakings with the chief intent of cut downing the likeliness of human mistakes. The new centre taxi strip allows more infinite for land aircrafts to steer, hence, cut downing the opportunity for runway incursions. Runway position visible radiation farther diminishes the opportunity of aircraft hits by warning the pilots of active traversing track. LAX should be sing a important decrease in track incursion incidents in the hereafter. The airdrome is in great demand of modernizing because the terminuss built half a century ago were merely non designed to manage the demands of the twenty-first Century. Renovating Tom Bradley International Terminal along with the other eight terminuss will pull more bearers to LAX. However, the airdrome is faced with a more serious issue- the deficiency of infinite for enlargement. The metropolis itself has grown to a point that the airdrome is wholly surrounded by edifices, so contrivers have about no infinite for the airdrome to spread out. All future airdrome terminal enlargements must be taken west of the present terminus composite, the belongings that is presently used for aircraft hangers and lading installations. It will be interesting to see the executable options contrivers are coming up with. On October 21, 2008, A Qantas Airlines Airbus 380 with 450 people landed at LAX. This marks the beginning of the superjumbo jet service in the West seashore, and is decidedly an indicant that more international riders are taking LAX. From the individual soil set downing strip in a wheat field to the 3rd busiest airdrome in the United States, LAX has come a long manner. Airport ‘s success is straight related with the local community. Today, southern California ‘s economic system has ne'er been so mutualist upon the air transit system. As the local economic system skyrocketed, airdrome must accommodate to the turning demands without giving safety and efficiency. The local community airdrome director, commissioners, and maestro contrivers must work together to guarantee the success of LAX in the twenty-first Century.Appendix: LAX Terminal Diagram and air hoses, SAIP
