Winds and the Pressure Gradient Force

Wind is the movement of air across the Earth’s surface and is produced by differences in air pressure between one place to another. Wind strength can vary from a light breeze to hurricane force and is measured with the Beaufort Wind Scale. Winds are named from the direction from which they originate. For example, a westerly is a wind coming from the west and blowing toward the east. Wind speed is measured with an anemometer and its direction is determined with a wind vane. Since wind is produced by differences in air pressure, it is important to understand that concept when studying wind as well. Air pressure is created by the motion, size, and number of gas molecules present in the air. This varies based on the temperature and density of the air mass. In 1643, Evangelista Torricelli, a student of Galileo developed the mercury barometer to measure air pressure after studying water and pumps in mining operations. Using similar instruments today, scientists are able to measure normal sea level pressure at about 1013.2 millibars (force per square meter of surface area). The Pressure Gradient Force and Other Effects on Wind Within the atmosphere, there are several forces that impact the speed and direction of winds. The most important though is the Earth’s gravitational force. As gravity compresses the Earth’s atmosphere, it creates air pressure- the driving force of wind. Without gravity, there would be no atmosphere or air pressure and thus, no wind. The force actually responsible for causing the movement of air though is the pressure gradient force. Differences in air pressure and the pressure gradient force are caused by the unequal heating of the Earth’s surface when incoming solar radiation concentrates at the equator. Because of the energy surplus at low latitudes for example, the air there is warmer than that at the poles. Warm air is less dense and has a lower barometric pressure than the cold air at high latitudes. These differences in barometric pressure are what create the pressure gradient force and wind as air constantly moves between areas of high and low pressure. To show wind speeds, the pressure gradient is plotted onto weather maps using isobars mapped between areas of high and low pressure. Bars spaced far apart represent a gradual pressure gradient and light winds. Those closer together show a steep pressure gradient and strong winds. Finally, the Coriolis force and friction both significantly affect wind across the globe. The Coriolis force makes wind deflect from its straight path between high and low-pressure areas and the friction force slows wind down as it travels over the Earth’s surface. Upper Level Winds Within the atmosphere, there are different levels of air circulation. However, those in the middle and upper troposphere are an important part of the entire atmospheres air circulation. To map these circulation patterns upper air pressure maps use 500 millibars (mb) as a reference point. This means that the height above sea level is only plotted in areas with an air pressure level of 500 mb. For example, over an ocean 500 mb could be 18,000 feet into the atmosphere but over land, it could be 19,000 feet. By contrast, surface weather maps plot pressure differences based at a fixed elevation, usually sea level. The 500 mb level is important for winds because by analyzing upper-level winds, meteorologists can learn more about weather conditions at the Earth’s surface. Frequently, these upper-level winds generate the weather and wind patterns at the surface. Two upper-level wind patterns that are important to meteorologists are Rossby waves and the jet stream. Rossby waves are significant because they bring cold air south and warm air north, creating a difference in air pressure and wind. These waves develop along the jet stream. Local and Regional Winds In addition to low and upper-level global wind patterns, there are various types of local winds around the world. Land-sea breezes that occur on most coastlines are one example. These winds are caused by the temperature and density differences of air over land versus water but are confined to coastal locations. Mountain-valley breezes are another localized wind pattern. These winds are caused when mountain air cools quickly at night and flows down into valleys. In addition, valley air gains heat quickly during the day and it rises upslope creating afternoon breezes. Some other examples of local winds include Southern California’s warm and dry Santa Ana Winds, the cold and dry mistral wind of France’s Rhà ´ne Valley, the very cold, usually dry bora wind on the eastern coast of the Adriatic Sea, and the Chinook winds in North America. Winds can also occur on a large regional scale. One example of this type of wind would be katabatic winds. These are winds caused by gravity and are sometimes called drainage winds because they drain down a valley or slope when dense, cold air at high elevations flows downhill by gravity. These winds are usually stronger than mountain-valley breezes and occur over larger areas such as a plateau or highland. Examples of katabatic winds are those that blow off of Antarctica and Greenland’s vast ice sheets. The seasonally shifting monsoonal winds found over Southeast Asia, Indonesia, India, northern Australia, and equatorial Africa are another example of regional winds because they are confined to the larger region of the tropics as opposed to just India for example. Whether winds are local, regional, or global, they are an important component to atmospheric circulation and play an important role in human life on Earth as their flow across vast areas is capable of moving weather, pollutants, and other airborne items worldwide.

The Content Of A Video Based On A Practical Intervention...

The following report seeks to summarise the content of the video based on the topic selected from the assigned chapters 11 and 12; ‘anchoring’. The first section will summarize the content of the video and examine the concept used to explain the ‘anchoring’ principle, specifically using it in a practical intervention for the British Heart Foundation. The report will then go on to describe the application of the principles of â€Å"Made to Stick† by Chip Dan Heath used in the project, focusing on the implementation of the principles throughout the video. Section 1: (Summaries the content of the video) + provide additional information Anchoring is defined as a process where â€Å"different starting points yield different estimates, which are biased toward the initial values† (Tversky and Kahneman, 1974). The British Heart Foundation was selected as an organisation for a practical intervention. The project focused on their website and how anchoring could be used to increase donations for this charity. Anchoring is frequently used in marketing campaigns and pricing strategies; the iPad launch by Apple in 2010 was used as an example of best practice in our video. The original clip of the iPad launch was first shown as a concrete and credible example of anchoring, followed by a reenactment of a possible board meeting at the Apple Headquarters.

The Harnswell Sewing Machine Company free essay sample

This paper aims to support Natalie York, the operations manager at Harnswell Sewing Machine Company (HSMC), in her intent to improve product quality in the company. In addition to analyzing production process data of half-inch cam rollers and explaining the results, this paper also gives advice on which actions Natalie should take and how she should approach the CEO and founder of her company. Phase 1 Based on the given description of the HSMC, points 1, 2 and 7 of Deming’s 14 points for management seem to be most lacking in the company. . Create constancy of purpose for improvement of product and service. 2. Adopt new philosophy. 7. Adopt and institute leadership. There is a huge need of organizational transformation in the HSMC and its CEO and founder, Mr. Harmswell, is currently not aware of this need. According to his own words (â€Å"if it ain’t broke, don’t fix it†), he is not striving for constant improvement and does not act proactively. We will write a custom essay sample on The Harnswell Sewing Machine Company or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Rather than supporting his employees in thinking about how to improve their working environments, Mr. Harmswell relies on his past experiences. He even actively discourages his employees from â€Å"making waves† and uses fear as an instrument to paralyze the people in his organization (â€Å"What am I going to do with you if you keep coming up with these ridiculous ideas†). This indicates that he is rather supervising than leading his employees. Natalie York should think very carefully about her next steps and focus on the specific problem she discovered and not the whole production process when she approaches Mr. Harmswell next time. Natalie will only be able to implement changes when she comes to her boss backed with profound data analysis. Besides the data-based evidence of problems in certain parts of the production process, Natalie should show Mr. Harmswell the positive impact changes will have on the profit of HSMC. Keeping her language simple and her explanations easily understandable is another key for the success of her next steps. After Natalie successfully implemented a couple of smaller changes in parts of the production, Mr. Harmswell might rethink his attitude towards constant improvement and give her more freedom to have a positive impact on the organization. Phase 2: Using the given data about the diameter of cam rollers, we use Minitab to create a â€Å"Xbar-R Chartâ€Å", as shown in Chart 1 of the appendix. From this chart, we can draw the conclusion that Day 17 is below the LCL, out of control limit. Therefore one can say the whole process is out of control. Natalie notices that the average diameter of batch 17 is extremely low compared to the average diameters of the other batches. Our recommendation to Natalie is that she should check what happened on Day 17 to find the reasons for these out-of-control-results. As the next step, Natalie should take the required actions for solving the discovered problem. Phase 3: After Natalie’s further investigation, it turns out that the reason for the particularly bad results of work on Day 17 is the low temperature in the morning on which the batch was produced. By installing a thermostat in the manufacturing hall they solve this problem. Now, what Natalie should do next is to take this special batch out of the data and draw another Xbar-R chart. After excluding this special case from the data, Natalie can evaluate the rest of the data independently from this â€Å"special event†. The new Xbar-R chart shows this one special batch is not the reason why cam rollers always fall short. From the new chart, Natalie might identify what might be the other causes that result in the shortage. For further information, please refer to Chart 2 in the appendix. Natalie and Jim install the thermostat and set the heating control so that heats turns on half an hour before the machine starts to work in the morning. These actions have a positive impact on improving the product quality as the scrap defects were caused by cold temperatures, affecting the normal running of the equipment. After setting the heating control, the machine will warm up to acceptable temperatures in the cold weather. By doing this, any scraps caused by the abnormal status of the equipment in cold weather will be avoided. Phase 4: Chart 3, the histogram of diameters, and Chart 4, the stem-and-leaf display, show that the range is from 0. 5072 to 0. 5077, which means all cam rollers meet the lower specification of 0. 5072 but some exceed the upper specification 0. 5075. The mean of the 150 sample diameters’ is 0. 5075. The mean diameter equals the upper limit of the diameter. There are 71 cam rollers having a diameter of 0. 075, accounting for 47. 3% of all samples; 49 cam rollers have diameter of 0. 5076, accounting for 32. 7% of all samples; 7 cam rollers have diameter of 0. 5077, accounting for 4. 7% of all samples. Chart 5, the pie chart of distribution of diameters, shows that there are 56 cam rollers which have a larger diameter than 0. 5075, while there are only 23 cam rollers wi th diameters below 0. 0575. 56 of the 150 rollers, comprising 37. 3%, are above the specification value. Therefore 37. 3% of them will be reclassified into a different and less costly category, which decreases total revenues and profits of HSMC. If this percentage is applied for the total years’ production, out of 7000 cam rollers 2614 will not be available for sale at normal price. Phase 5: Dave Martin, the machinist at HSMC, is already aware of the reasons why he has been producing many oversized cam rollers. With operating room of 0. 0003 inch, he has been aiming for the upper level of diameter because he did not want to produce undersized cam rollers which have to be scrapped. Dave Martin simply did not want to have trouble with Mr. Hanswell and other senior managers of the company. Natalie first needs to persuade Dave to adjust his aim to the exact center value and try to manufacture accordingly. Of course, Natalie needs to give Dave an assurance that he would not be held liable for the results. Because Natalie already has all the data she needs to conform to her forecast, we think it is time to go to Mr. Harmswell. She should show him that there exist some real problems and tell him the importance and positive benefits of adopting changes at HSMC. But she should be very careful not to overload her boss with too many graphs and numbers.

Influence of Men on Sarahs Development in the End of the Affair

Authored by Graham Greene, The End of the Affair is a fascinating must-read play featuring three major characters namely Maurice Bendrix, Sarah and Henry who help him criticize the conspiracies existing in relationships. Bendrix is a â€Å"middle aged bachelor who meets Sarah and Henry while beginning to write a new book† (Almeida Para.1). Henry, on the other hand, works with the British government as a civil servant.Advertising We will write a custom essay sample on Influence of Men on Sarah’s Development in the End of the Affair specifically for you for only $16.05 $11/page Learn More He is also the husband to Sarah. Sarah indulges in multi-relationships with men. She quickly forms a relationship with Bendrix, who becomes a slave of her love. Unfortunately, their love does not last. â€Å"One day, they survive a bombing during WWII. When she discovers that he is alive, she tells him that the affair is over† (Almeida Para.1). Her de cision is final, as she vows never to turn back to Maurice. Bendrix, on the other hand, does not heed to this decision. He encounters Henry in the city who fears that his wife is seeing someone else. Although, people can influence others in a positive way, the paper reveals how Sarah’s involvements with the two key characters: Henry and Bendrix, had negative impacts. Sarah’s involvement with Henry substantially impairs her perceptions about men to the extent that she results into adultery. Unaware of Maurice’s involvement with his wife, Henry â€Å"invites Maurice for a drink, expressing his worries that Sarah might be having an affair with someone† (Almeida Para.2). Upon realizing this, Maurice decides to hire an investigator who confirms the fears expressed by Henry. However, on realizing that Maurice had hired an investigator, Henry also gets clues that Maurice could have been priory involved with his wife. The setting of The End of the Affair takes pl ace when England was recovering from aftermaths of the Second World War. Right from the onset of the play, encounters of an unhappy couple, Henry and Sarah, are evident. In the course of their relationship, things roll from excellent to sour. The two separate. Henry admits his irresponsibility as a husband: He is not a first-class and true lover to his wife Sarah. Henry’s inability to play her marital obligations plays a significant role in making Sarah become unfaithful to him. This inability also contributes to her engagement in short term affairs. Sarah and Bendrix meet in 1939. The novelist Bendrix comes in to fulfill the function that Henry leaves unfulfilled.Advertising Looking for essay on american literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More The two profess to engage in an undying love for each other. As Berardinelli notes, â€Å"Henry worked long hours on the war effort, Maurice and Sarah spent time in Mauriceà ¢â‚¬â„¢s flat. But on a night, when Maurice was seriously wounded in a German air raid, the relationship abruptly ended† (Para.2). As a way of reiterating, Bendrix denounces his earlier promises for undying love. Instead, he substitutes them with hatred, which she immensely directs to Sarah. Perhaps borrowing from her experience with Henry, Sarah believes in true love for Bendrix. In fact, she says, â€Å"All today Maurice has been sweet to me†¦He tells me often that he has never loved another woman so much† (Greene 46). Sarah clearly comes out to express what guides her love. She has had experience in the past with Henry, a man who is still her husband. Nevertheless, this experience has influenced her development quite negatively. She cannot trust words from a man who proclaims to love her irrespective of the number of times he utters them. The fact that she loves a man makes her believe in his love. She says, â€Å"If I stopped loving him, I would cease to belie ve in his love† (Greene 46). Expressing love in words would have no good to her, as men say them jokingly. Sarah deviates from the belief that love can exist between two people without physical contact based on her experience with Bendrix. Bendrix’s perception about love erodes Sarah’s perceptions about the same to the extent that the two spend some intimate time in his flat where they engaged in sex. Sarah’s involvement with men, particularly Henry and Bendrix, inculcates an enormous feeling of insecurity in her. Consequently, she indulges in new relationships without considering quitting the previous ones. In this regard, she reckons, â€Å"I have always wanted to be liked or admired. I feel a terrible insecurity if a man turns on me if I love a friend. I do not even want to lose a husband. I want everything, all the time, everywhere† (Greene 55). Although, she appreciates that love entails exploration of an unknown world. She has an incredible fe ar to explore and go through unknown encounters alone. She must seek an attachment elsewhere. Henry acts as a man who provides security to Sarah in case the new pursuits go haywire. In case she ends into extra marital affairs, she always goes back to him as she looks for another relationship. When she leaves Bendrix, she gets to yet another affair with a man by the name Richard Smythe while still maintaining Henry as her husband. This perhaps indicates that Sarah does not intend to take chances that are evidently unpredictable in the world of love. Sarah’s involvement with Henry shaped her attitudes towards men in such a way that she doubts their genuineness when they proclaim to love a woman. For instance, Sarah claims, â€Å"It is a strange thing to discover and believe that you are loved, when you know that there is nothing in you for anybody but a parent or a God to love† (Greene 70).Advertising We will write a custom essay sample on Influence of Men on Sarahà ¢â‚¬â„¢s Development in the End of the Affair specifically for you for only $16.05 $11/page Learn More According to Sarah, therefore, the only true love that a woman can be sure of is the one between her and God. For her, love has no boundaries and ends. It can continue to exist even if the two persons who were once engaged move apart and cease to contact each other. Unfortunately, men such as Bendrix, who Sarah has had their love experience, believe that â€Å"some physical intimacy is necessarily† (Berardinelli Para. 4). He cannot believe in something that he cannot smell, feel, see, taste or even hear. Sarah’s involvement with him presents two incongruent perceptions about love. This confirmed Bendrix’s beliefs. It fails to honor what Sarah believes about love. In fact, Bendrix declares that he â€Å"would rather be dead or see you dead than see you with another man† (Greene 23). However, their love turns out sour when the two separate for years. Bendrix’s involvement with Sarah had the consequences of shaping Sarah’s belief about love that prompted her to consider propagating acts unfaithfulness. He evidently had involved himself in numerous relationships, which were promiscuous in nature. Bendrix confirms his promiscuity when he says, â€Å"It was as if quite suddenly after all the promiscuous years I had grown up. My passion for Sarah had killed simple lust forever. Never again would I enjoy a woman without love† (Greene 46). It would widely possess some substance to argue that Sarah could not entirely and solely trust Bendrix. Bendrix past affairs ended without signals. Sarah would only end up deceiving herself that her relationship with Bendrix would last forever. Bendrix exemplifies this fact when he says, â€Å"†¦when I tried to remember her voice saying ‘don’t worry,’ I found I had no memory for sounds. When I tried to remember it, it was anonymous â €“ just a woman’s voice† (Greene 119). It is clear that Bendrix was set to forget Sarah since the breaking of their connectivity. Sarah says, â€Å"I’ve only made two promises in my life. One was to marry Henry; the other is to stop seeing you. And I’m too weak to keep either† (Greene 71). Sarah believed in true love that does not end even when people break contacts. However, her involvement with Bendrix may have widely contributed to the changing of this perception. Sarah, who believed in true love, also left him for unclear reasons. In conclusion, The End of the Affair is a masterwork that presents the influence that people can have on others. Sarah is such an illustration of women negatively influenced by two men: Bendrix and Henry. The author presents the physical and spiritual components of love in an intriguing way. He explores on the theme of adultery coupled with intimacies and jealous associated with it. To accomplish this, the influenc e of men on Sarah’s development is a recurring topic. By scrutinizing Bendrix and Henry’s involvement with Sarah, the paper declares the influence negative towards the Sarah’s cognitive development in issues pertaining to love.Advertising Looking for essay on american literature?

The Role of Flexibility in the Australian Context

Introduction The following essay is on the need for flexibility of labour in the Australian context. This essay will discuss the role of flexibility in the Australian context. There will be evaluation of the advantages and disadvantages of flexible work arrangements from the perspective of the employer as well as employee. The essay will look into the Equal employment Act in Australia, and its role in the flexible work conditions. The essay will also include the perspective of the work conditions in the country.Advertising We will write a custom essay sample on The Role of Flexibility in the Australian Context specifically for you for only $16.05 $11/page Learn More Background Flexibility of work is a major labour relation issue that has effect on both the labour and the management. Flexibility comes from the need for the management to adjust with the dynamism of the labour market that results from the development of the company and the way in which empl oyees want to work. The survey results released by the Australian Bureau of statistics show that fifty percent of the workers do not have choice over their work start time and finish time (Fagan, 2009). Twenty eight per cent of the employees had incomes that varied from one pay period to the next. Thirty-seven percent had hours that varied per week and they had to stay alert to work on call. This form of uncertainty and unpredictability of work makes it necessary for both the employer and the employees to have flexible working mentality to allow them work harmoniously. Currently, 1.4 million workers in Australia work in shifts, which are organized by the management. This especially applies to the mining industry and service industries such as hotels (Fagan, 2009). Flexible work conditions take the pluralist approach of industrial relations where the view recognizes that entities in an industry both the employee and the employer are powerful with different goals and objectives. The m anagement role is to coordinate and persuade employees to work whereas the labour unions are the legitimate representatives of employees and they represent them through collective bargaining. With this perspective employees are able to negotiate the number of hours collectively as well as the working conditions (Hyman, 1975). However, with most of the companies employing non-unionized workers to meet their labour needs and the employees opting for flexible rather than fixed working conditions it is becoming necessary to institute mechanisms to tackle flexibility of work to suit both the employer and the employee. The government of Australia instituted Equal Employment Act that spell out flexible work arrangements that are legally recognized. They help the employees to choose arrangement such as the number of hours to work, modes of work and when to enjoy benefits such as holidays (Atkinson Meager, 1986).Advertising Looking for essay on labor law?

Get your first paper with 15% OFF Learn More The most popular kind of work arrangements is the part time work or the job sharing where workers work part time or they share the work with another person such that each work two days a week. The other common arrangement is the shifts, where employees work in shifts especially in the mining industry where the work may go on for twenty-four hours every day. The other popular arrangement is the telecommuting where workers may perform some of their duties away from office or at home such as making calls. The other work arrangements is the compressed work hours where an employee may work continuously for forty hours in five days a week rather than in two weeks (Bhave Budd, 2008). Numerical flexibility The notion of numerical flexibility is becoming common than it was before as the modern worker is no longer encouraged to work through adjustments in labour prices. They are encouraged by the working conditions and terms of work. With the functioning markets of goods and services, company must also adapt to the high season and low demands on labour. When the company is in low season, it may lay off some workers due to reduced tasks and responsibilities. During the high season, the company may have to bring in external workers or hire additional labour to meet the demand of the products or services (Befort Budd, 2009). Numerical flexibility has two aspects with the first one being external flexibility. This is where the company outsource workers when it is in need of extra labour. This is through short-term contractual workers who work for a given season. The second aspect of numerical flexibility involves adjustment in the number of hours or days worked by the employees such that they may work for extra hours or overtime in high seasons and few hours during low seasons (Morrell, 2011). The company applying the internal numerical flexibility usually adjusts the labour within the company such that it does not lay off workers or hire extra workers from outside. The fewer hours done in low season compensate the additional hours done during the high season. This type of numerical flexibility applies in many companies, as they avoid repeated layoffs and recruiting procedures that are tedious and expensive. The internal numerical flexibility is also considered advantageous to the employees due to the job security and the employee does not have to keep on changing jobs (Budd, 2004).Advertising We will write a custom essay sample on The Role of Flexibility in the Australian Context specifically for you for only $16.05 $11/page Learn More Functional flexibility This refers to the extent in which the employee can transfer to another work. It is how the employees can perform different tasks within the company. Functional flexibility refers to the number of tasks an employee can engage in the organisation. In functional flexibility when there is high season, the employee may do additional tasks. For instance, an employee may work as a technician and a receptionist in the company, which allows flexibility within the organisation. It involves having the labour force appropriately positioned to use different technologies. However, for this to be done the company must focus its resources on training the employees to perform different tasks (Fagan, 2009). Role of flexibility in Australian context With the Australian Equal Employment opportunity Act of 1984, the companies had to adjust their regulations and layoff activities as the law discriminated against layoffs based on conditions such as pregnancy or sickness. The companies had to adjust their schedules to fit the need of workers such as maternity leaves, parental leave and other needs of the workers. The first role played by the work arrangement flexibility is reducing employee absenteeism. The absenteeism was usually because of stresses and sickness that made workers redundant. However, with flexib ility the employees can adjust their work to fit them such that they can balance their work and other activities (Reilly, 2001). Flexibility in work arrangements has enhanced morale and job satisfaction resulting to increased and improved efficiency in the work. When working hours fit the employees, it results in increased motivation to work. With increased morale, the productivity goes high and the company benefits from increased revenue (Wallace, 2003). With the increased morale resulting from the increased productivity, the employees are more energetic and creative. This is because they have the choice to work during the time when they are most productive and effective in the job. The flexibility allows the employees to concentrate on the work they are doing unlike in scenarios where time of working is inflexible and they are unable to attend other issues thereby affecting productivity as well as morale. With the increased productivity, the organisation and the employee benefit ( Hyman, 1975).Advertising Looking for essay on labor law? Let's see if we can help you! Get your first paper with 15% OFF Learn More The flexibility in work arrangements reduces work stress and burn out because the flexibility allows the employee to relax and recuperate energies unlike in scenarios where the work timelines are fixed and do not have time for employee to relax (Kaufman, 2004). The other contribution of the work flexibility is that it has reduced the role and the influence of labour organisations. This is because with the numerical flexibility where workers work on contract, it is very hard for the workers join unions. Most of the contracts state that they do not want anyone who is unionised. This challenge makes most of the workers who work on contact basis not to be members of labour unions. Functional flexibility allows the employees to start the work in many aspects of the job and cannot complain of overworking, as it is part of the in-house arrangements to shift the working of the employees (Salamon, 2000). The companies in Australia on the other hand have benefited from the development of the work and they can now develop their work as well as increase their responsibilities on the development of the company. The companies have experienced low levels of industrial actions such as low employee turnover and strikes. This is because of the flexible work arrangement measures that suit both the employer and the employee (Webb Webb, 1897). Employer’s perspective on the flexibility â€Å" The work arrangements are advantageous to the employees as they result in increased productivity. The productivity comes from the need to reduce stress in the workplace and motivation that comes from working when it is appropriate (Nichols, 1997). The other advantage of the work arrangements procedures is that it reduces costs such as hiring and recruiting when the company is in need of extra labour as well as freeing the company from compensation obligations when an employee is fired. This is because the employees’ can work under flexible work arrangements offering the employe e a chance to determine the appropriate time of work such that the employer can hire workers to work during the time when the labour is needed most. This prevents the employer from paying redundant workers (Kaufman, 2004). The work arrangement flexibility has reduced the influence and the bargaining power of the trade unions significantly such that they cannot be influential as they were previously. With reduced bargaining power, the employers can negotiate better terms with the employees. Most of the companies that adopt numerical flexibility employ workers on short-term contracts, which make it hard for the employees to unionise. The flexible work conditions can be attributed to the reduced levels of strikes and industrial actions in the companies (Kelly, 1998). The work arrangements are costly to the company especially in instances where the company has to outsource to meet the demand for labour. It is also disadvantageous to the company as it has to retrain the staff on the vari ous aspects of the work to make them flexible such that they are deployable to do different tasks and duties (Mullins, 2005). The flexibility especially the numerical flexibility where the company employs on short term contracts result in reduced employee loyalty as many employees are influenced by job security and they may not be loyal to the companies that do not offer job security to them (Salamon, 2000). The other aspect of management is that the work arrangement involves the management relinquishing its supervisory powers. This is because some of the arrangements such as telecommuting where the employees work from home or away from the office make it hard for the employer to supervise them. The employer’s must consider whether an employee is appropriate to the work arrangement as individuals who need close supervision in their work cannot be fit for telecommuting arrangements (Nichols, 1997). Employee’s perspective The work arrangement flexibility is disadvantageo us to the employees because it enables them to live a balanced life where they manage family and work. This is an important achievement for many people to balance their attention to both the work and the family (Reilly, 2001). The other advantage is that it enables the employees to work at the optimum time, and relax when tired. It allows the employees to choose when to go for holidays and when not to. With this kind of flexibility, the employees manage to be productive in their work and achieve results (Budd, 2004). The arrangements are however disadvantageous to most of the employees because they involve short term jobs that end after the season is over, which makes the employees insecure (Wallace, 2003). The other disadvantage is that the work arrangements makes collective bargaining less effective as the employee can only negotiate conditions that suit him or her personally not collectively. This means that bargains with the employer are usually personal and not collective, whic h is a disadvantage to the employee. The company may flout the previous working arrangement agreed upon and the individual employee may not manage to initiate a legal proceeding against the company. The other disadvantage is that in some instances employees are forced to work for many hours to compensate for the hours they were not working (Morrell, 2011). The last disadvantage of the work arrangements is that most of the times employers do not consult the employees when designing the flexible work arrangements to determine the best kind of flexible work arrangements to suit the employees (Salamon, 2000). Conclusion Discourse on work arrangements is significant to the development of the work conditions. The development of appropriate work conditions allows the employees to work towards the development of their own company as well as their life. For the work arrangement flexibility have effect both the employer and the employee must be in the planning stage such that the arrangement will meet the personal need of the employee as well as benefit the company. Assessing the work flexibility arrangements helps to determine whether the arrangements are effective or not. Evaluating the arrangements is important in ensuring that the arrangement achieves the set objectives. References Atkinson, J. Meager, N. (1986).

Frances and Americas Health Care Systems Comparison

Frances and Americas Health Care Systems Comparison Introduction The America spends around 15% of its GDP on the costs of health care, and this percentage exceeds the OECDs spending being 8.8% almost twice and the French costs, which constitute 11.2% of its GDP, in 40%. France health care spending is 11% of the national output, matched up to 15% used in America in health issues, such as infant mortality (Skinner Garber, 2008).Advertising We will write a custom critical writing sample on France’s and America’s Health Care Systems Comparison specifically for you for only $16.05 $11/page Learn More Health care system in the United States has received a criticism due to the absence of universal medical coverage in contrast to the universal health coverage in France. Since French insurance coverage is basically obligatory, medical expenses are more largely allocated to the whole population. Even though laws in America permit particular kinds of health care offered to the uninsured patients, they inc rease health expenses for the insured; and these greater health care expenses are borne by the people looking for health care instead of society in general. Exclusive of the situation of greatly communicable diseases, the treatment, which offers a huge social advantage, is debatable in regard to an extra earning or income. This paper discusses and compares France and the U.S. health care systems. Health Care System in the United States Health care system in the United States has brought about more polarizing discussion. Some critics state that the U.S. provides the best health care structure in the world due to directly accessible health care technology and high-tech facilities that have been the point of reference in medical care. Others criticize the system of health care in America as being ineffective and uneven due to the point that it spends more money on medical care than any other country, and there are still a lot of uncovered people, managerial waste, and unreliable qualit y. Health care providers are mainly owned and controlled by the private operators, and health coverage offered by the government in the public health care system ensures around 62% of the total, and provision is provided by programs, such as Veterans Health Administration, TRICARE, and Medicare (Himmelstein Woolhandler, 2004). Most people under the age of 65 are covered by their employers; some purchase coverage on their own, while others are uncovered.Advertising Looking for critical writing on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More In the United States, 49.8 million people, 16.2 percent of the population, were uncovered in 2010, which showed an increase from 16 percent in 2009. In line with WHO, the U.S. allocates more on health care per capita, being $7,145; moreover, it raised the figure on health care as ratio of its GDP became 15.1 percent that was greater than of any other country surveyed in 2009. America was ranked the fourth highest level of public medical care expenditure per capita of $3, 430, following other nations with higher level of health care spending per capital, which were Monaco, Norway, and Luxembourg. In 2009, research in five states reported that health care debt made up to 46.2 percent of entire individual bankruptcies. In 2010, 62.2 percent of filers for bankruptcies declared an increased health care spending. Since then, medical expenses and the number of uncovered and underinsured became greater than before. Government Implication In 2010, President Obama passed a law, The Patient Protection and Affordable Care Act, which supported phased implementation over four years of an inclusive arrangement of authorized health coverage with reforms intended to remove different undesirable activities of the insurance providers. These activities address the areas, such as yearly and life coverage gaps, premium loadings, and necessary screening. It also establishes a least ratio of direct health care expenditure to premium income, and price competition strengthened by the formation of three standard insurance coverage stages, to allow open assessment by end users, and online health coverage services that enable consumers to assess prices and other service plans. Health care system offers subsidy to allow the low income earners to purchase insurance and conserve private health facilities and private insurance. The law enacted by President Obama includes provision related to the health care that is to be executed over seven years, and extending Medicaid eligibility for the public translating to 135 percent of the FDL (Federal Poverty Level), offering incentives to firms to allow medical benefits, forbidding refusal of coverage and denial of claims derived from the present situations. This law also creates health care insurance exchanges and supports subsidization of coverage premiums for the public, representing 400 percent of the Federal Poverty Level in order for their highest spending for yearly premiums to descend from 2% to 10% of earnings (Skinner Garber, 2008). It also disallows the insurers from instituting annual insurance or coverage caps and focuses more on the establishment of medical research. Commencing in 2014, the law will disallow insurers to refuse insurance to sick candidates, or demand certain conditions, for instance, advanced payments or premiums. The 2010 Acts entail coverage providers to cover more expenses, requiring that not less than 80% of premiums should be used in health care or ‘quality upgrading’ and complete medical coverage for immunizations and screenings through disallowing annual and lifetime caps that provide uneven distribution. Pros and Cons Medical researches in the United States, which are carried out in some institutions, such as Cleveland Clinic, the Mayo Clinic, and Harvard Medical School, are among the best in the world, and well-known due to the developments they do in medicine, mainly, because of the latest free-market structure.Advertising We will write a custom critical writing sample on France’s and America’s Health Care Systems Comparison specifically for you for only $16.05 $11/page Learn More For the people with employment and great benefits, or those who can pay for it, various American insurance programs are ranked among the best programs in the globe. Another benefit of the latest American medical care program is that taxpayers are not responsible for the cost related to giving health care insurance to all the people (Skinner Garber, 2008). Medical care expenses in the United States are more than in any country all over the globe, and its system where every person should be covered just serves to raise these expenses at the cost of the taxpayers. Most people assert that tax contributions would carry funds away from national security and education to finance newly established medical care sys tem. The noticeable drawback of the health care system in the United States is that though the taxpayers have used more of their income in the American health care, most researches report that Americans have not become healthier than people in other countries that spend less on health care than the US. There is huge amount of money used in American health care, and the government pays out more of its Gross Domestic Product (GDP) on medical system than any other nation. In 2008, the United States allocated almost 15% of its total GDP on health care (Skinner Garber, 2008). Another noticeable drawback of the health care system is that most people are either underinsured or uninsured, and the United States Census Bureau reported that in 2003, 65% of people were insured by health insurance controlled by the government while 15% of the population were uninsured. Health Care System in France The French government offers some series of varied and all-inclusive health care programs. For ove r 95% of the people, health care is either completely free or fully compensated (Snchez-Serrano, 2011, p. 30). The people also have the privilege to select among health care facilities, irrespective of their earning levels. Additionally, the waiting lists for surgeries, just like in the United States, are not found in France health care system. Medical care coverage in France is a section of the Social Security structure which is financed by income of the employees (60% of the accounts), imposed taxes from tobacco and alcohol, and payment provided by the revenue related to earning that composes capital revenues and retirement pensions.Advertising Looking for critical writing on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Apparently, it seems that medical insurances repay health care facilities more in the United States than in France. However, above 80% of French citizens have supplemental medical coverage, usually offered by their employers. Government Implications In the mid 2001, a law was enacted by the government enabling the health care system to offer more support to people in need in their every day tasks. In March 2002, the government also enacted a policy creating reimbursement for every accident related to health issue, regardless whether it is their own fault or not. These new policies were added to the previous confirmed policies, such as reimbursement rights in instances of illness prevention or pregnancy, health costs for employees and students, organized screening of particular disorder, and family planning. The ‘2012 Hospital Plan’ allocated with  £10 million is to allow the implementation of fresh investments with some major concerns, such as the reinforcing compleme ntarities among health care providers situated in certain area, the improvement of security system, and the automation of health care system (Snchez-Serrano, 2011, p. 30). In 2002, a law passed by the government addressed the rights of the patients on pain relief, in line with reimbursement for severe medical accidents, patient consent, availability of communication to the patient, and dignity of the patient. Pros and Cons People benefit from the ability to choose personal medical providers or doctors, and patients with long-term disorders or illnesses are allocated with more funds or 100 percent medical insurance coverage. The less income earners are provided with universal healthcare that is funded by taxes. Moreover, the medical expenses for the people suffering from the long-term illness are fully compensated, and they can confer with different practitioners or select university, private, public, general, or private health care providers. Health care systems have a loose edition of universal health care, denoting that the government made a controlled system that enabled medical care facilities and insurance providers to insure everybody (Snchez-Serrano, 2011, p. 30). Health care system in France also allows more funds to be used in medical costs due to the structure where the patients need to consult the doctor first, which adds more expenses. Comparison of Health Care Systems France health care spending of 11 percent of the national output is lower as compared to 15% used in America in health issues, such as infant mortality. Health care systems of both France and the U.S. allow patients to have different selections when looking for medical care or providers (Budrys, 2011, p. 135). In France, patients commonly get interventions directly from a professional or consultant, while in the United States, the expansion of HMO signifies that most patients should receive the consent of a ‘primary care physician’ before looking for specific interventio ns. The U.S. system can be annoying to patients, but also preserve the spending directed to health care costs when the primary care physician considers it unimportant. Like France, America provides both the public and the private insurers, and the issue that especially concerns the system of the United States is the control of the private component over the public one. In France, being jobless signifies reduced tax funds going into Assurance Maladie’s treasury, but in the U.S., it means that a person may lose his or her coverage (Budrys, 2011, p. 135). In France, regulation also limits the medical coverage providers from appropriately pooling policies and reforms by risk group, which increases medical coverage premiums in general. Medical systems normally take advantage of reduced regulation and an inclination towards a medical arrangement where insurance assumes to a function of offering for dependent and upsetting health care emergencies among groups for which the possibili ty for these incidences is roughly the same. In the U.S. health care system, reforming the way in which practitioners and other providers are salaried is an essential aspect in providing system transition, especially, in the common payment system, and generates incentives to offer extra services, instead of improved and high-value approaches to care for conditions. Conclusion Health care systems in France and America undergo more expenses caused by the application of medical coverage for regular medical care where the key receiver does not receive the full cost of the health care. It appears that the U.S. spends more funds in health care system than any other country in the world, including France. Different measures and reforms are needed in both systems to provide satisfying services and regulate amount of the funds allocated to these systems. References Budrys, G. (2011).

The role of the school principals in the care of gifted students Dissertation

The role of the school principals in the care of gifted students - Dissertation Example Now, there are many ways of assessing how children perform, interact with their learning and solve different problems, beyond just reading and writing, to find out who is gifted (Murray, 1994). The definition of giftedness according to Marland report (1972) as cited in Klein, et. al (2007, p. 574) is "Gifted and talented are those ... with demonstrated achievement and/or potential ability in ... (a) general intellectual ability, (b) specific academic aptitude, (c) creative or productive thinking, (d) leadership ability, (e) visual and performing arts, and (f) psychomotor ability.† This definition now include skills which are not easily manifested, and to successfully and credibly label someone as â€Å"gifted† many processes are necessary than mere parental observation. Research indicates that the gifted individuals form a diverse group and it is not something which can be associated with a single trait. The giftedness of a child is associated with the psychological well -being of a gifted child, the matching of his skills with education provided, and the personal characteristics of the child, for example, his life situations, his nature and/or self-perceptions (Niehart 1999, p. 15). 1.1 Context Saudi Arabia puts a premium on education based on their belief that one’s principal duty in life is to acquire intellectual and spiritual perfection in his thinking, perceptions and belief (Gulen 2004, p. 202). Hence, the Ministry of Education was established in 1953. It sets overall standards for the country’s educational system and assumes responsibility for policy making and planning curriculum, teacher and superintendent training and special education (Al-Hamdan, n.d., p. 2). The system consists of twelve years. The educational ladder begins with six years of elementary school, three years of intermediate school and three years of high school. The educational aim of schools is to develop students’ different skills, abilities and crea tivity (Al-Hamdan, n.d., p. 3). Gifted education is incorporated in the system stemming from two administrative branches in the Ministry of Education that are tasked to identify and serve the gifted. They consist of four units namely the programs unit; the planning, coordination and training unit; the identification unit and the administrative communication unit. Special programs are provided for the identified gifted students. These include Thursday programs, summer programs and enrichment programs for the gifted within the school day (Al-Hamdan, n.d., p. 3). As stated by Aljoghaiman (2007) one example of enrichment programs is the one developed for elementary schools. Programs include teacher training for gifted students so specialized programs can be effectively implemented through appropriate teaching methods for the enhancement of gifted abilities in all areas. One example is the grouping of gifted students for a period of time during the school day when they engage in activiti es while passing through four levels of the program. â€Å"The first level concentrated on preparation and it included basic thinking skills, such as brain storming, some of the skills in the CoRT Program for Thinking, and Scamper Strategy. The second level included teaching the Creative Problem Solving Program. The third level consisted of the Future Problem Solving Program, and in the fourth and last level, gifted students went through the research program: a comprehensive program of self regulated learning that included different thinking skills. This program
