Ghost Light from Dead Galaxies Sheds Light on Ancient Galaxy Interactions

Did you know that astronomers can learn about galaxies that died long ago? Thats part of the story of the cosmos that the  deep cosmos-gazing  Hubble Space Telescope  was built to tell. Along with other telescopes on the ground and on orbit, it fills in the story of the universe as it peers out at distant objects. Some of its most fascinating objects are galaxies, including some that formed in the infancy of the universe and are now long gone from the cosmic scene. What stories do they tell?   What Hubble Found Studying long-dead galaxies sounds like it would be impossible. In a way, it is. Theyre no longer around, but it turns out, some of their stars are. To learn more about early galaxies that no longer exist, Hubble observed dim  light from orphaned stars that lie some 4 billion light-years away from us. They were born billions of years ago and somehow were ejected at high speed from their original galaxies, which themselves are long gone. It turns out some kind of galactic mayhem sent these stars reeling across space. They belonged to a galaxies in a massive galaxy called Pandoras Cluster. The light from those far-flung stars provided clues to a crime scene of truly galactic proportions: as many as six galaxies were somehow torn to pieces within the cluster. How could this happen? Gravity Explains a Lot Each galaxy has a gravitational pull. Its the combined gravity of all the stars, clouds of gas and dust, black holes, and dark matter that exist in the galaxy.  In a cluster, you get the combined gravitational pull of all the galaxies, and that affects all of the members of the cluster. That gravity is pretty strong. In addition, galaxies tend to move around within their clusters, which affects the motions and interacts of their cluster-mates. Add those two effects together and you set the scene  for the destruction of some not-so-lucky small galaxies that happen to get caught in the action.  They get stuck in a squeeze play between their larger neighbors as they travel, Eventually, the strong gravity of the bigger galaxies pulls the smaller ones apart.   Astronomers found clues to this destructive shredding of galaxies by studying the light from stars scattered by the action.That light would be detectable long after the galaxies were destroyed. However, this predicted intracluster glow of stars is very faint and is quite a challenge to observe.These are extremely faint stars and they are brightest in infrared wavelengths of light. This is where Hubble comes in. It has very sensitive detectors to capture that faint glow from the stars. Its observations helped scientists study the combined light of about 200 billion stars that were cast out from interacting galaxies. Its measurements showed that the scattered stars are rich in heavier elements like oxygen, carbon, and nitrogen. This means they are not the first-ever stars formed. The first stars consisted mainly of hydrogen and helium, and forged heavier elements in their cores. When those earliest ones died, all the elements were cast into space and into nebulae of gas and dust. Later generations of stars formed from those clouds and show higher concentrations of heavy elements. It is the enriched stars that Hubble studied in an effort to track what happened to their galactic homes.   Future Studies Zero in on More Orphan Stars Theres still a lot to figure out about the earliest, most distant galaxies and their interactions. Everywhere Hubble looks, it finds more and more distant galaxies. The farther out it  peers, the further back in time it looks. Each time it makes a deep field observation, this telescope shows astronomers fascinating things about the earliest times in the cosmos. Thats all part of the study of cosmology, the origin and evolution of the universe.

Sophocles Oedipus the King free essay sample

This paper analyzes the Greek play by Sophocles `Oedipus the King`. The author states Oedipus is one of the most famous names in Greek mythology. He believes that Oedipus was not an unwitting victim but rather had a clear hand in his own demise. Although the author thinks that one might curse the stars, he finds that the sense of doom ultimately has its origination in the nature of the human character. In this paper the author also explains why he feels that the term Oedipus complex is an inappropriate reading of the play. `The `back story` the play provides to the opening image is also indicative of Oedipus arrogance as well. Oedipus first dialogue with his brother-in-law reveals that the plague has its roots in the murder of the original King of Thebes, Laius. Oedipus reacts with horror to this news.

Rapid technological change Essay Example

Rapid technological change Essay Rapid technological change and the globalization of economic activity is re-structuring the North American economy, and with it the nature and future of work in Canada. There is now a clear, though barely-articulated question as to whether secure, full-time, adequately-waged employment will be available to much of the North American workforce, at least over the next 30-60 years, or whether jobless growth, under-employment and contingent employment will become the norm, as is increasingly the trend in other industrialized nations. Canada has shifted towards a knowledge- based economy, reflecting an upward trend across most industries with the explosive growth of the information and communications technology sector over the past decade. This transition has been a long and continuous process, crossing all provinces and the urban-rural sectors, with a general increase in the importance of skills, knowledge and human capital among many types of firms and establishments. In fact, the proportion of knowledge workers increased steadily over the last three decades, reflecting a growth trend that began long before the high-tech boom of the  1990s (Beckstead, 2003). Many organizations struggle to build the leadership capacity that they need to thrive in the ever-changing global business environment. Canadians revealed a pervasive anxiety about such issues as joblessness, under- and over-employment, conflicts between work and family, workplace inequalities, retiring with dignity, and jobs for youth.   At the same time, they indicated that they want more from their working lives not only economic security and a decent standard of living, but opportunities for personal development and the fulfilment that comes with making a contribution to society. Canadians want personal rewards from work other than just decent pay and economic stability (Lu, 1999). To address this concern, corporations must introduce quality improvement programs to critically assess the directions in which work seems to be headed, and determine how they can meet the aspirations that individual Canadians have for their work life. It is therefore necessary to give higher priorit y to improving the quality of work for it will have numerous benefits for individual workers since the characteristics of our jobs and work environments determines our quality of life.

Although Canadians received high marks from the United Nations for their high quality of life, questionable points as to the quality of work have still emerged throughout the decades. It is true that perceptions of job insecurity may have risen in the 1990s, but one can argue that this was not a permanent development but rather linked with high unemployment and downsizing and these fears have since abated with the fall in unemployment. Indeed, I believe that a case can be made that there is a strong long-term upward trend in job quality, although subject to short-to-medium term reversals because of negative cyclical developments. Factors behind this trend include the mechanization of the workplace, which reduced drudgery and industrial accidents, the employment shift from the goods sector to the service sector, and the concentration of net emplo yment growth in professional and managerial occupations. In order to motivate their workers, employees must provide a pleasant environment that motivates its subordinates- considering their growth and welfare in every endeavor. But what constitutes a high- quality workplace? Perhaps it would be a lot easier to describe a good place of work by using a poor agency as a starting point. When we ask the employees of such a site they answer by mentioning unclear responsibilities, no feedback, unfairness in wages, promotions and dismissals, no opportunity for personal development, poor physical environment, in brief a place characterized by uncertainty, hostility and fear. In contrast, a high quality workplace is one that meets employees needs and delivers results for the employer (Lowe, 2000). It is one where people are treated with respect, have good communications, do interesting work that gives a sense of accomplishment, have supportive co-workers, have ample opportunity to develop their skills, and can balance work and life. The knowledge-driven economy has brought with it a major transformation—jobs involving the most complex type of interactions make up the fastest-growing segment in many industries (Bennett, 1990). As a result, formal learning once or twice a year doesn’t provide the experience or knowledge that workers require. There needs to be a significant shift of budgets and resources from formal learning settings to informal situations where the majority of learning actually takes place. This interactive presentation will examine current trends and include case studies from the public and private sectors about how smart organizations are using communities of practice. All instances of successful development are ultimately the collective result of individual decisions by entrepreneurs to invest in risky new ventures and try out new things. In labour circles, there has been growing awareness of the problems posed by a globalizing economy working in concert with technological innovation in the workplace. I then turn to the more difficult question of how one thinks about appropriate strategies for administrative building. Making the quality of work a higher priority requires a fundamental shift in management thinking. Employees need to be treated as assets rather than costs and managers need a long-term vision of how people development will pay off. To work methodically in improving workplace quality all links must hold, in the long chain from management policy, through the administration system, programs and processes, all the way out to the individual employee. This kind of quality assurance of management requires a complete and consistent structure , and it must be possible to measure present status and improvements. What are required, though, are a dedicated top management and great patience and persistence in the implementation phase. A substantial and permanent improvement of workplace quality is a long project, but quite possible to achieve, without exceptional extra cost. The end result is an executive management that is satisfied with the performance, quality and capacity for change of their organization. Employees experience a work-place characterized by security, fairness, participation, cooperation and opportunities to grow. Managers have the challenging tasks they seek and feel the right balance of independence and support. To achieve this goal, workers must use a collaborative approach to solving workplace problems. This framework must be based on the fundamental principle that joint efforts by employees, their unions and management will improve the quality of services delivered. Consultation, co-development and collective bargaining are all appropriate mechanisms for the creation of win win solutions to workplace concerns. To help bring about this basic change from an adversarial to a more joint problem solving approach requires the rebuilding of trust and a willingness on both sides to explore different approaches in short what is often referred to as a cultural change. Such change, while difficult, is nevertheless possible. It can be encouraged by revising and modernizing the system and by providing for a single redress system for individual workplace complaints throughout the system and by establishing a new agency to assist the parties in finding mutually acceptable solutions in collective bargaining. A good, stable and productive labour management regime should be the foundation to good human resources management in a unionized environment. The employees in Canadas public service and broader public sector are almost completely represented by certified bargaining agents, a situation that we do not expect to change. Finding a way to build effective working relationships between unions and management thus becomes a key public policy issue.

7 Helpful Time Management Activities for College Students

7 Helpful Time Management Activities for College Students Time management is probably one of the most important skills for surviving and thriving in college - and in life. Its a wonder more schools dont include it as a class for freshmen. Juggling classes, labs, study time, work, exercise, extracurricular activities, volunteer work, parties, and sleep is a major challenge. These tips will help you create an organized life so you can succeed at everything you do! 1. Use a Planner Whether its an app or a plain old spiral notebook, a planner is essential for keeping track of your schedule. Dont make the mistake of telling yourself youll remember it all. Use only one system, and write down everything - including time to sleep and time to play! 2. Determine Your Priorities Speaking of sleep and play, some people need more of some activities than others. Effective time management depends on your bodys needs, your personal values, and your ability to prioritize. If you can get by on six hours of sleep, thats great. But if you know you need at least eight hours in order to function, dont even pretend that six will work. 3. Go to Class First of all, youre probably paying top dollar for those classes. Second, trying to make up for what you have missed almost always takes longer than the actual class would have. Borrowing notes and doubling up on assignments is a pain. So save yourself time and trouble and go. Go in your pajamas and shades if you have to. Just show up. And some instructors give attendance points, so why not maximize your grade just by breathing in the right room? 4. If At First You Dont Succeed†¦ If you try using a planner and it doesnt work for you, dont give up. Try something else. The cold, hard truth of modern adult life is that you have to get in the habit of scheduling your day. Theres just too much going on to wing it without missing something. Find the system that works for you. It doesnt have to be the hottest thing on the market. You might do better by downgrading your system to something simpler. 5. Leave Some Room Remember that you need time to commute between activities, use the bathroom, grab a drink, and so forth. Dont sandwich things so tightly that you have no room to breathe. Include time cushions between appointments as much as you can. Youll also want to block out large chunks of free time to accommodate those unexpected things, such as a midnight fast-food run or Game of Thrones or True Detective marathon. 6. Just Say No You cant do it all and expect to get good grades and graduate on time. Once in a while, youre going to have to turn down a party in favor of sleep, or a workout in favor of extra study time. Remember those priorities we talked about earlier? Write them down if you have to. Number them in order of importance. Then, when faced with two choices, youll easily know what to do. You may not always make the best choice, but most of the time, youll be able to stick to your guns. 7. Plan for Next Semester You can try to arrange next semesters class schedule to suit you better. If you spent most of the current semester hitting Snooze or skipping those 8 a.m. classes, do everything you can to avoid early morning courses. And if you ended up with weird chunks of time between classes that were too short to do anything productive, try to schedule next semesters courses back to back. Get them all out of the way, and then youll be left with larger chunks of time that are more flexible for your needs. Tell your advisor about your priorities, and he or she can help you work out an ideal class plan. Time management doesnt have to be a drag. Once you go through this list and get in the habit of planning, it will become second nature. And youre sure to see an improvement in your grades and your overall quality of life.

The Logic of Collective Action by Mancur Olson

The Logic of Collective Action by Mancur Olson There are a lot of government policies, like airline bailouts, that from an economic perspective dont make any sense at all. Politicians have an incentive to keep the economy strong as incumbents are reelected at a much higher rate during booms than busts. So why do so many government policies make such little economic sense? The best answer to this question comes from a book that is almost 40 years old: The Logic of Collective Action by Mancur Olson explains why some groups are able to have a larger influence on government policy than others. In this brief outline, the results of The Logic of Collective Action are used to explain economic policy decisions. Any page references come from the 1971 edition. It has a very useful appendix not found in the 1965 edition. You would expect that if a group of people has a common interest that theyll naturally get together and fight for the common goal. Olson states, however, that this is generally not the case: But it is not in fact true that the idea that groups will act in their self-interest follows logically from the premise of rational and self-interested behavior. It does not follow, because all of the individuals in a group would gain if they achieved their group objective, that they would act to achieve that objective, even if they were all rational and self-interested. Indeed unless the number of individuals in a group is quite small, or unless there is coercion or some other special device to make individuals act in their common interest, rational, self-interested individuals will not act to achieve their common or group interests.(pg. 2) We can see why this is if we look at the classic example of perfect competition. Under perfect competition, there is a very large number of producers of an identical good. Since the goods are identical, all firms end up charging the same price, a price that leads to a zero economic profit. If the firms could collude and decide to cut their output and charge a price higher than the one that prevails under perfect competition all firms would make a profit. Although every firm in the industry would gain if they could make such an agreement, Olson explains why this does not happen: Since a uniform price must prevail in such a market, a firm cannot expect a higher price for itself unless all of the other firms in the industry have this higher price. But a firm in a competitive market also has an interest in selling as much as it can, until the cost of producing another unit exceeds the price of that unit. In this there is no common interest; each firms interest is directly opposed to that of every other firm, for the more the firms sell, the lower the price and income for any given firm. In short, while all firms have a common interest in a higher price, they have antagonistic interests where output is concerned.(pg. 9) The logical solution around this problem would be to lobby congress to put in place a price floor, stating that producers of this good cannot charge a price lower than some price X. Another way around the problem would be to have congress pass a law stating that there was a limit to how much each business could produce and that new businesses could not enter the market. Well see on the next page that The Logic of Collective Action explains why this will not work either. The Logic of Collective Action explains why if a group of firms cannot reach a collusive agreement in the marketplace, they will be unable to form a group and lobby the government for help: Consider a hypothetical, competitive industry, and suppose that most of the producers in that industry desire a tariff, a price-support program, or some other government intervention to increase the price for their product. To obtain any such assistance from the government, the producers in this industry will presumably have to organize a lobbying organization... The campaign will take the time of some of the producers in the industry, as well as their money. Just as it was not rational for a particular producer to restrict his output in order that there might be a higher price for the product of his industry, so it would not be rational for him to sacrifice his time and money to support a lobbying organization to obtain government assistance for the industry. In neither case would it be in the interest of the individual producer to assume any of the costs himself. [...] This would be true even if everyone in the industry were absolutely convinced that the proposed program was in their interest.(pg. 11) In both instances, groups will not be formed  because the groups cannot exclude people from benefiting if they do not join the cartel or lobbying organization. In a perfect competitive marketplace, the level of production of any one producer has a negligible impact of the market price of that good. A cartel will not be formed because every agent within the cartel has an incentive to drop out of the cartel and produce as much as she possibly can, as her production will not cause the price to drop at all. Similarly, each producer of the good has an incentive not to pay dues to the lobbying organization, as the loss of one dues paying member will not influence the success or failure of that organization. One extra member in a lobbying organization representing a very large group will not determine whether or not that group will get a piece of legislation enacted that will help the industry. Since the benefits of that legislation cannot be limited to those firms in the lobbying group, there is no reason for that firm to join. Olson indicates that this is the norm for very large groups: Migrant farm laborers are a significant group with urgent common interests, and they have no lobby to voice their needs. The white-collar workers are a large group with common interests, but they have no organization to care for their interests. The taxpayers are a vast group with an obvious common interest, but in an important sense they have yet to obtain representation. The consumers are at least as numerous as any other group in the society, but they have no organization to countervail the power of organized monopolistic producers. There are multitudes with an interest in peace, but they have no lobby to match those of the special interests that may on occasion have an interest in war. There are vast numbers who have a common interest in preventing inflation and depression, but they have no organization to express that interest. (pg. 165) In a smaller group, one person makes up a larger percentage of the resources of that group, so the addition or subtraction of a single member to that organization can determine the success of the group. There are also social pressures which work much better on the small than on the large. Olson gives two reasons why large groups are inherently unsuccessful in their attempts to organize: In general, social pressure and social incentives operate only in groups of smaller size, in the groups so small that the members can have face-to-face contact with one another. Though in an oligopolic industry with only a handful of firms there may be strong resentment against the chiseler who cuts prices to increase his own sales at the expense of the group, in a perfectly competitive industry there is usually no such resentment; indeed the man who succeeds in increasing his sales and output in a perfectly competitive industry is usually admired and set up as a good example by his competitors. There are perhaps two reasons for this difference in the attitudes of large and small groups. First, in the large, latent group, each member, by definition, is so small in relation to the total that his actions will not matter much one way or another; so it would seem pointless for one perfect competitor to snub or abuse another for a selfish, antigroup action, because the recalcitrants action would not be decisive in any event. Second, in any large group everyone cannot possibly know everyone else, and the group will ipso facto not be a friendship group; so a person will ordinarily not be affected socially if he fails to make sacrifices on behalf of his groups goals.(pg. 62) Because smaller groups can exert these social (as well as economic) pressures, they are much more able to get around this problem. This leads to the result that smaller groups (or what some would call Special Interest Groups) are able to have policies enacted that hurt the country as a whole. In the sharing of the costs of efforts to achieve a common goal in small groups, there is however a surprising tendency for the exploitation of the great by the small.(pg. 3). Now that we know that smaller groups will generally be more successful than large ones, we understand why the government enacts many of the policies it does. To illustrate how this works, well use a made-up example of such a policy. Its a very drastic over-simplification, but its not that far out. Suppose there are four major airlines in the United States, each of whom is near bankruptcy. The CEO of one of the airlines realizes that they can get out of bankruptcy by lobbying the government for support. He can convince the 3 other airlines to go along with the plan, as they realize that theyll be more successful if they band together and if one of the airlines does not participate a number of lobbying resources will be greatly diminished along with the credibility of their argument. The airlines pool their resources and hire a high-priced lobbying firm along with a handful of unprincipled economists. The airlines explain to the government that without a $400 million dollar package they will not be able to survive. If they do not survive, there will be terrible consequences for the economy, so its in the best interest of the government to give them the money. The congresswoman listening to the argument finds it compelling, but she also recognizes a self-serving argument when she hears one. So shed like to hear from groups opposing the move. However, its obvious that such a group will not form, for the following reason: The $400 million dollars represents around $1.50 for each person living in America. Now obviously many of those individuals do not pay taxes, so well assume that it represents $4 for each tax-paying American (this assumes everyone pays the same amount in taxes which again is an over-simplification). Its obvious to see that its not worth the time and effort for any American to educate themselves about the issue, solicit donations for their cause and lobby to congress if theyd only gain a few dollars. So other than a few academic economists and think tanks, nobody opposes the measure, and it is enacted by congress. By this, we see that a small group is inherently at an advantage against a larger group. Although in total the amount at stake is the same for each group, the individual members of the small group have much more at stake than the individual members of the large group, so they have an incentive to spend more time and energy trying to change government policy. If these transfers just caused one group to gain at the others expense, it wouldnt hurt the economy at all. It wouldnt be any different than someone just handing you $10; youve gained $10 and that person lost $10, and the economy as a whole has the same value it had before. However, it does cause a decline in the economy for two reasons: The cost of lobbying. Lobbying is inherently a non-productive activity for the economy. The resources spent on lobbying are resources that are not being spent on creating wealth, so the economy is poorer as a whole. The money spent on lobbying could have been spent buying a new 747, so the economy as a whole is one 747 poorer.The deadweight loss caused by taxation. In the article The Effect of Taxes on the Economy, its illustrated that higher taxes causes productivity to decline and the economy to be worse off. Here the government was taking $4 from each taxpayer, which is not a significant amount. However, the government enacts hundreds of these policies so in total the sum becomes quite significant. These handouts to small groups cause a decline in economic growth because they change the actions of taxpayers.

Customer Commitment Essay Example | Topics and Well Written Essays - 500 words

Customer Commitment - Essay Example roll’s guitar, on a scale of 1 to 10 the ethical breach would be 9 since it is clearly very unethical for a company to ignore repeated consumer complaints, especially when the services provided by United Airlines includes the comfort and satisfaction of their passengers. Since Mr. Carroll has already sent complaint letters multiple times, the best course of action to pacify him and come to agreement on how the complaints will be settled without the company having to admit total fault and giving his demands is by sending him an apologetic reply immediately and inviting him for a personal dialogue concerning his complaints and the possibility of settling the issue and gaining his trust back. This step can be further guided by Maxham & Netemeyer’s ethics process model (2003) which is customer-centered by putting all customers in the shoes of their clients, so that they could empathize with them and provide appropriate responses. It is expected to provide favorable outcomes for both United Airlines and Mr. Carroll if executed properly. While this step may seem simple, it is a necessary action to prevent Mr. Carroll from feeling that his complaints have been completely ignored and making him feel that he is an unimportant customer, as well as to prevent him from taking actions that can affect United Airlines as a whole prematurely (such as posting songs or complaints through the internet). In addition to the aforementioned mitigation steps for the issues with Mr. Carroll, as Regional Manager a meeting with other concerned divisions and supervisors must be called in to fully give the details that lead to the situation, to explain the repercussions that can happen and affect the impression and trust of important clients, stakeholders, and the public due to Mr. Carroll’s dissatisfaction and ignoring his complaints, and to create the terms of settlement that will be offered to Mr. Carroll such as creating a list of possible settlements and allowing him to choose only

Biotech foods :: essays research papers

In Michael Pollan’s essay, â€Å"Playing God in the Garden†, we are introduced to the New Leaf Superior, a genetically engineered potato. This is not the first of its kind, for it is only one of the many foods that are products of an emergent development here in the United States. Monsanto and other giant transnational companies are carrying out a dangerous global experiment by introducing large numbers of genetically engineered foods into our diet. Genetic manipulations can result in unanticipated harmful effects, and because genetically engineered foods are not sufficiently tested, this experiment not only jeopardizes the health of individuals, but also affects the natural flow of nature.   Ã‚  Ã‚  Ã‚  Ã‚  Pollan writes, â€Å"genetic engineering overthrows the old rules governing the relationship of nature and culture in plants.† He argues in his essay that the â€Å"old rules†, or natural (organic) ways of farming are no longer being valued, but rather overthrown and replaced by this new technology. We get the impression that Pollan does not trust this genetically engineered food because it is completely unnatural.   Ã‚  Ã‚  Ã‚  Ã‚   There are numerous benefits to genetic cultivation as well as many farmers who agree with and practice this way of life. Biotechnology food produces its own insecticide, and its final product is better looking than that of organically grown food. Due to genetically modified food’s unique and unknown nature, however, there is potential for adverse health side effects. On page 467, Pollan writes: â€Å"When I called the E.P.A. and asked if the agency had tested my Bt potatoes for safety as a human food, the answer was . . . not exactly. It seems the E.P.A. works from the assumption that if the original potato is safe and the Bt protein added to it is safe, then the whole New Leaf package is safe . . . the original potato is safe, so that left the Bt toxin, which was fed to mice, and they ‘did fine, had no side affects’†. Pollan here implies that it is unknown whether or not these foods are safe. The fact that these products were tested on mice does not mean that they are safe for people. Maybe genetically engineered food does not harm people in any way, but no one knows for sure. It is impossible to predict the impact of genetically engineered food; it is a matter of waiting for and observing future consequences.   Ã‚  Ã‚  Ã‚  Ã‚  Genetically modified food farmers, such as Dan Forsythe and Steve Young, all agree that this new gene technology will supply plentiful amounts of food, but they themselves would not eat these foods.

Making Choices Guide Essay

As we age our bodies and lives take on many different changes. Some of these changes are for the better and then there are changes that are not so much in our favor. Our health status is the one thing that can vary from time-to-time as we age, and for this we have to prepare ourselves for the many possibilities of needing long term care (LTC). Once the need for LTC is evident, there are many decisions to be made, and a long list of things to take into consideration. Finances, costs, demographics, and independence, are just a few variables to consider when choosing where you or a loved one will be spending the next chapter in life. Finances are the most important variable to take into consideration, mainly because plain and simple; the care is going to cost. Whether a LTC facility or a person’s home is going to be the place where the care is delivered, there will be some expenses accrued. Personal income, annuities, long term care insurance, savings, government programs (Medi care & Medicaid), Veteran’s Benefits, and reverse mortgages are just a few payment options available for LTC. There are more payment options becoming available through new financial products as our populace ages. When it comes to the costs of delivering the care, and where it is to be delivered, a lot of things come into play. Residing in a LTC facility brings about a multitude of expenditures compared to staying at home or aging in place. In 2010, semi-private rooms averaged about $200 a day in a nursing home, and about $230 for a private room, and a one bedroom apartment in an assisted living facility averaged about $3,300 a month. Those costs are not all inclusive. There is usually a cost for added services such as private laundry, additional activities or programs. According to LongTermCare.gov (n.d.), it is wise to think now about how your  current residence and community will support your needs as you age and require long term care services. Staying at home or aging in place has its expenses too. A home owner’s expenses are a little less costly if they had their home built to their satisfaction to begin with. This eliminates having major work done on the home to accommodate the need for LTC. The adding of handrails and ramps, throughout the home is much cheaper than living in a LTC facility for a month. Another advantage of aging in place is the caregiver could be free of charge if it is a friend or relative. On the other hand, the cost of home health aides and homemakers range from $19 to $22 per hour. There are also programs to assist those who choose to age in place. One program is The Older Americans Act. According to LongTermCare.gov (n.d.),The Older Americans Act is a Federal program designed to organize, coordinate, and provide home- and community-based services to older adults and their families. These services and programs assist the elderly and older adults in remaining independently in their communities. Local transportation services, in-home personal care, meals delivered for the homebound (and available in the community), and homemaker services are just a few of the programs and services available through the Older American Act. These services are also extended to Native Americans. Having the feeling of belonging where you are is a comfortable feeling. When making the decision on where you plan to live your next chapter of life, it is important to keep in mind to find somewhere comfortable and familiar to you. Nothing is more familiar to a person than where they are – home. . Here is where the demographics can come into play. Most individuals are familiar with their communities and the people within them, so it is a little easier to locate services and programs in the area. Community-based programs are mostly targeted to help the elderly, disabled, and older adults to reestablish and preserve their optimal level of self-care, while preventing and prolonging unsuitable and unwanted institutionalization. According to Gibson, (1995 – 2014), these programs stress partnership with the participant, family, caregiver, primary care physician, and the community in working toward maintaining personal independence. An outstanding and reliable social support system can be a valuable asset, regardless of where your next chapter in life may take place. Having family, friends, and the support of others (staff if in a  facility) can have a positive impact and influence on the individual receiving the LTC. Regular visits and communication can also influence positive motivation. According to AHRQ (2006), social support and interaction within the facility also relate to quality of life satisfaction and reduced isolation and depressive symptoms, which is important for independent individuals. Other variables that can affect a couple’s or individual’s choice on a LTC facility includes whether or not the facility is Alzheimer’s friendly. If the individual who is needing the care has Alzheimer’s, you would want to make sure the staff are properly trained to care for them. Other things to consider is whether or not there is a wing or ward for individuals with Alzheimer’s., or if the facility is safeguarded for these individuals to roam around indoors and out. .It is important to know the staff to resident ratio. There need to be enough staff to service the residents at all times. Visiting is a variable to be considered also. Not only having family and friends visit, but if the individual’s mobility is at a doable level, are they able to do an outing with a family member or friend?  When the time comes to make the choice of where your next chapter in life is going to be spent, be sure to thoroughly research your options. Make sure that the services and programs you choose are not only available now, but also available for the future. There is an endless list of variables to consider. You would want to make sure the facility and staff are licensed and certified to provide the care needed. It is also important to know if the facility has full access to the medical care needed. A very important variable is behavior management. Knowing how the facility deals with various types of behaviors is significant to another resident’s safety. Question the facility as to whether they use chemical or physical restraints, or if the individual is shut off from the main area. These are just some of the variables and questions to consider. Keep asking questions until you are fully satisfied and happy with the answers. When older adults and the elderly are devoted and participating personally in their care, they tend to be more satisfied with where they are and the decisions they have made to get to that point.

HNA case study Essay

1. What contributed to HNA’s success in the China Airline Industry? 1. China’s prosperous market conditions Rising middle class (rising per capita income) Entry into WTO ïÆ'   growth in imports and exports Migration of rural population into urban cities Influx of foreign investment 2. Deregulation of civil aviation market 3. Strategic Decisions: Unconventional approach for a regional start up airline – chose to compete as a trunk line feeder Development of feeder routes in Western China – consistent with government plan to develop the â€Å"Silk Road† Effective acquisitions that helped them to expand faster 4. Effective utilization of capital markets (internal and external) to expand operational scale and lower operating costs 5. Culture Encompasses Chinese culture and Western modern management Lazy Ant Theory and Swapping System 6. Quality Excellent flight safety standards Punctuality rate is first in China 7. Clear Strategy: To be low cost provider Focused on cost structure and operating efficiency Cost per ASK was very low Lower maintenance cost Similar model of planes Ran aircrafts longer Investment in technology Lower staffing cost per ASK 8. Started outside CAAC – did not have to adhere to government standard. Forced them to be more aggressive 9. Strong Interrelation among the blocks of businesses contributes to increasing revenue for their airline business 2. What are the challenges that the company faces at both the business and corporate levels? Business Unit Price of Oil (airline) High financing costs (airline) Entry of budget hotel competitors (hotel) Entry of upscale international franchise (Hilton etc) into hotel industry (hotel) Credit rating firm downgraded the airline to second lowest rating Corporate level High debt level puts the company into difficulty of raising funds to expand Relative industries block – important to maintain relevance to its airline business 3. Was the company’s increasing breadth a distraction to the airline business or a route to competitive advantage? The increasing breadth might work in favor for HNA’s airline business as they seek to revamp itself into Grand China Airline. By increasing its breadth, it can help to strengthen the new airline brand name to other parts of the world. Particularly for the hotel business, HNA can utilize them to promote the brand presence of its airline business to tourists. However, HNA need to be careful of the breadth of business it can extend to. It should be kept within the boundaries of the airline industry such that whatever industries it is trying to expand to, it should contribute directly to its airline business (obvious synergy). For example, the departmental store business does not create synergy with the airline business.

Collective Nouns in Spanish

Collective Nouns in Spanish See in this selection how a singular noun can refer to a group of more than one person. Excerpt from news article: El Papa Francisco dejà ³ claro que su primer objetivo era estar con el pueblo. Y asà ­ fue. El vehà ­culo que llevaba al Santo Padre y a [presidenta brasileà ±a Dilma] Rousseff desde el aeropuerto hasta la ciudad avanzà ³ arropado por una multitud de gente que se acercaba a tratar de ver de cerca al  «Papa de los pobres », sin vallas de seguridad que los separase. (The bracketed description of Rousseff was added to the original for clarity here.) Source: ABC.es, a Madrid-based news site. Retrieved July 23, 2013. Suggested translation: Pope Francis made clear that his first goal was to be with the people. And so it was. The vehicle that transported the Holy Father and [Brazilian President Dilma] Rousseff from the airport toward the city proceeded while enveloped by a crowd of people who got near in order to see the pope of the poor from nearby without security barriers to separate them. Key grammatical issue: This selection shows how collective nouns - pueblo, multitud and gente - are singular in form even though they sometimes are translated as plurals. Although both pueblo and gente are translated here as people, note how in Spanish they are singular words. Pueblo is used with the singular definite article el, and the singular verbs se acercaba (from the reflexive verb acercarse) and separase (a subjunctive form of separar) go with multitud de gente. We do the same thing in English - the most common translations for multitud, crowd and multitude, are singular even though they refer to multiple people. If pueblo and gente seem confusing, its only because they arent translated here as singular terms (although in a different context pueblo could refer to a small town). Other notes on vocabulary and grammar: Personal titles in Spanish - such as doctora in la doctora Snchez (Dr. Snchez) and seà ±or in el seà ±or Robles (Mr. Robles) - are not capitalized, and it would have been acceptable here to write el papa Francisco instead of el Papa Francisco. However, it is not unusual to capitalize the titles of certain people, Catholic popes among them, out of respect. When talking about people using their titles, the definite article (such as el in el Papa Francisco or la in la doctora Snchez) is used. If you were speaking to these people using their titles, however, you would not use the article. Dejar claro is an idiom meaning to make clear. Dejar en claro means the same thing and is more frequently used. Primer is the  apocopated form of primero. Llevar is a common verb typically meaning to carry.Note the double use of the personal a after llevaba. It is used here both before Santo Padre (al  is the combined form meaning a plus el) and before Rousseff. The personal a is also used befor e the phrase in angular quotes. The preposition desde often suggests motion from a place, in this case the airport. Motion toward is indicated by hacia.While was used in the translation for clarity. There is no equivalent word used here in the original Spanish. Arropado is the past participle of arropar, which typically means to wrap. However, it would be usual in English to say that someone was wrapped by a crowd. But the image the verb conveys is one of being closely surrounded, and enveloped seemed to work fine, although other phrases might have been used as well. Acercar usually means to bring nearer. In the reflexive form, as here, it usually means to approach or to get nearer. Tratar is a common verb often meaning to try. Angular quotation marks are used in the same way as standard double quotation marks. They are more common in publications from Spain than those from Latin America. Note how the comma after pobres is placed outside the quote marks rather than inside as it would be in American English. Valla is a word for fence. The term vallas de seguridad usually refers to small, metallic, portable fencelike structures that are used to control crowds and keep people in orderly lines.

Writing For People Who Write

Writing For People Who Write Writing For People Who Write Writing For People Who Write By Michael If you want to convince young people to do something, do you write for young people? Or do you write for people whom young people listen to? Years ago, people thought of communications as a hypodermic needle or a magic bullet. Prepare your message and shoot it into your audience. One problem with that approach is that most people dont enjoy needles. They enjoy bullets even less. Another problem with that approach, as Ive said before, is that its impossible to inject your message into other peoples brains and expect it to always mean the same thing to them as it does to you. A third problem with the hypodermic needle tactic is that people usually dont make important decisions simply because they read an article or a book. They make important decisions after talking with other people. They want to be reassured that theyre doing the right thing. Or they may not really understand what they just read. Your friend may be able to explain the point more meaningfully than the writer could, because your friend understands you better than the writer does. Ideas are often communicated in a two-step flow, a communications model that was conceived by sociologists Paul Lazarsfeld and Elihu Katz in the 1950s. An advertisers sells a product to the cool kids, who sell the other kids on it so they can be cool too. A scholar writes an article that nobody can stay awake to read, except for a popular blogger who restates the ideas and starts a wind storm of controversy. Sociologists often talk about elites and opinion leaders, but for young people (and for most of the rest of us), the people who really influence our opinions may not have a title before or after their names and may not live in mansions. As a teenager, I was influenced by social misfits with original ideas. A humble, well-informed person could be an opinion leader for you. The owner of an art gallery in my town is one of the best listeners I know, but when she recommends a restaurant or suggests a shortcut, I listen to her because shes lived here for forty years. If you want to convince young people with your writing, you could first ask the question, Do young people even read? If they do, what do they read? Or, if they dont read, who do they listen to? Who do they watch? And what do those people read? On one end of the flow are the millions of dollars spent answering those questions. On the other end are the fifteen-year-olds sending instant messages to their friends. If the advertisers cant influence the fifteen-year-old writers, they will have wasted their millions.

Why Marijuana Should Not Be Legalized Essay Example | Topics and Well Written Essays - 250 words

Why Marijuana Should Not Be Legalized - Essay Example The arguments of Nathan were actually appropriately substantiated and credible due to his medical background. Therefore, his expertise on the profound effects of marijuana is validated. In fact, he confirmed that â€Å"I am also a physician who understands that the negative legal consequences of marijuana use are far worse than the medical consequences† (Nathan par. 2). But despite the obvious negative effects, it was deemed more advantageous to promote for its legalization given the following reasons: (1) at the current status of marijuana still being considered prohibited by law; there apparently continues continued trade and sale which apparently contributes to vagrant criminal activities through illicit drug use and trade; (2) the continued popularity of marijuana leads to â€Å"the potential for adulteration of black-market cannabis and the substitution of even more dangerous copycat compounds† (Nathan par. 9); (3) as emphasized, â€Å"natural marijuana poses much less danger than synthetic cannabinoids -- legal or otherwise† (Nathan par. 9). His arguments are therefore worth reflecting.

In addition, the absence of training center requires from Alotaibi Business Group to send their employees to outside the organization training centers and it is very costly for the reason that Alotaibi Business Group has a staff of 2000 people. The establishment of a new training center at the Alotaibi Business Group premises will offer an excellent support for in-house staff training and handling. It will also offer an excellent support for management of staff working and operations. In fact, the development of this training center will potentially reduce the overall human resource training cost to 50%. So there are a lot of new opportunities for the business such as cost reduction, time and money saving and so many more. This project will have some exclusion. These elements will not be a part of this project or a training center. The first element is the recruitment of a staff trainer that will not be a part of this project. Here this project will not entitle any process of recruiting new staff members and their interviews. The next important factor is that this project will not involve the staff food and eating arrangement. Here we will not be responsible for arranging refreshment or lunch for the staff. The successful establishment of a new training center for Alotaibi Business Group will offer them a lot of benefits. In this scenario, one of the

Nelson Mandela - Essay Example These conditions kept on prevailing until in 1911 the Mines and Works Act stated that the Black workers could not be engaged as cheap semi-skilled laborers and this prohibited Black workers from seeking skilled work. In 1914 the National Party (NP) under General Hertzog made the law that the right to vote belonged to White and was not extended to Blacks. In coming years Blacks were deprived of the right to own their lands. The years went by and Blacks were subjected to discrimination by the Whites. Encyclopedia of Britannica describes apartheid as, policy that governed relations between South Africas white minority and nonwhite majority and sanctioned racial segregation and political and economic discrimination against nonwhites. It was in 1948 when the apartheid law was introduced which prohibited marriage of White and Non-White marriages and sanctioned White only jobs. The population was classified into White, Black and Colored. The Blacks had to carry pass books all the time containing their fingerprints, photos and information to access Non Black areas. There was discrimination in education, medical care and public services, and Blacks were always considered inferior to Whites. In 1951 the Bantu Authorities act established homelands for Blacks, their own lands were divided into separate homelands in which they had to live and in order to travel to another homeland they needed a passport, thus in other words they became alien to their own country. Whosoever did not abide by the law were subjected to injustices. Severe penalties were enforced on people and they were put in prison where brutal torture killed them. The statistics below show the result of apartheid law policies; It was through these hard times when a man rose up from between to combat these terrible practices of apartheid. Nelson Mandela was born on 28th July 1918, and dedicated his life to

Contrast And Comparison Of Urban And Rural Religion History Essay

Contrast And Comparison Of Urban And Rural Religion History Essay This paper explores Roman Britain Religion namely the urban and the rural religion in the Romano-British Period. The archaeological examples which are of great value in finding contrast and comparison of the rural and urban religions help us to develop the theme of the paper. The paper is organized in such a way that it touches upon the main religious trends in Roman Britain ( two main religions: Pagan and Christianity which existed in Roman Britain). Contrast and Comparison of the Urban and the Rural Religion in the Romano-British Period The religious situation in the Roman Empire was rather difficult and complicated. All the variety of cults and religions which were represented in the Roman Empire can be divided into several groups. Among them are the cults which symbolize the main idea of the Roman Empire the worship of Emperor. The other ones are the worship of traditional Olympian Gods and the religions of local people which were conquered by the Romes. (Ireland, 1986) Religion in Roman Britain is of special interest. It is known from the history of Britain that Roman Britain which occupied some part of the island of Great Britain belonged to the Roman Empire from AD 43 to AD 410. It was one of the numerous provinces of Roman Empire. (Esmonde, 1989) At that period there were such religions as pagan religion and Christianity. The goal of this paper is to find the contrast and comparison of urban and rural religions in the Romano-British period by means of different archaeological examples founded on the territory of Britain. (Hening, 1984) THE MAIN TYPES OF RELIGION IN ROMAN BRITAIN There were several types of religion in Roman Britain which are represented by the following religious trends: the Graeco-Roman and Barbaric Paganisms, Mithraism and other Eastern Cults and Christianity. (Ward, 1911) The Celtic Caste of Druids who were considered to be the first people of Britain were declared to be an outlaw by Claudius. Their defense of the sacred groves was a failure. The Romance ruined them on the island of Mona. Nevertheless, the worship of Celtic pagan Deities existed in the period of Roman rule.(Frere and Tomlin, 1991) TOWNS AND CITIES OF ROMAN BRITAIN Different towns and cities in Roman Britain appeared in different periods of Roman rule. It is very interesting to find information concerning the activities, religions and monuments by the examination of the archaeological records which were found during numerous excavations carried out on the territory of Britain. (see fig.1) Of course, these records are incomplete due to preservation and opportunity to excavate. (The Association for Roman Archeology) Fig.1 Archaeological excavations at York. York Archaeological Trust According to the research materials of the Association for Roman Archeology, the best preserved and explored Roman towns and cities are the following ones: Wroxeter, Silchester, Verulamium. (see fig.2) There are also some written sources which were found during the excavations. These sources tell about some examples of events Aurelius Victor (about death of Severus in York) and Tacitus Anales. (The Association for Roman Archeology). Fig.2 Reconstruction of the center of the town in Roman Britain Wroxeter. You can find a bath house and the basilica in this picture. Illustration by Ivan Lapper. English Heritage The Distinguishing Features of Towns in Roman Britain. In order to compare urban religion and rural religion in the Romano-British period, it is necessary to find some distinguishing features of towns in Roman Britain. They include the following elements: A great deal of houses for town dwellers A center for the government of the town Manufacture and trade buildings: shops, warehouses, workshops, markets, hospitals places for different cultural activities such as theaters, bath houses, taverns, amphitheaters a special religious places temples and statuaries.(Millet,1990) There are many streets in any town of Roman-British period. The cemeteries are situated around the town. URBAN RELIGION IN ROMAN BRITAIN AND SOME ARCHAEOLOGICAL EXAMPLES It is known that Roman rule allowed both the Romans and he local people who were conquered by them to worship numerous gods and goddesses. That is why there was a growth of temples and shrines to different deities. Before the advent of Christianity the Imperial Cult was considered to be one of the main religious aspects.(see fig.3) The Emperor was a so called mediator between the people and the gods. (Mattingly, 2000) Fig.3. Bronze Bust of Emperor Hadrian, The British Museum The town of Colchester was the most important place for the Imperial Cult. The main religious elements included temples, altars and shrines. (Collingwood, 1956) Temples were special houses for the Gods. The action of worship took place at the altars where different outdoor rites were organized. Shrines were special places of Gods presence. For example, the complex at Colchester had typically Roman style buildings. (Collingwood, 1956) It is interesting to notice that most of shrines were located in the country side and only some of them could be found in the towns. (The Romans in Britain) The experts in the sphere of archaeology confirm that there was a wide fusion and adoption of Roman Gods to the established local deities. The people venerated to several Gods with the same attributes. For example, Sulis-Minerva at Bath. (Religion in Roman Britain) A great number of temples and shrines to various deities were found in the towns and cities of Roman Britain: The Capitolium in Verulamium which represented a shrine to the Capitoline Triad of Jupiter, Juno and Minerva. An inscription to a Serapis/Osiris temple in York Londons Mithraeum Different epigraphical sources which referred to Cult centers of Cybele and Isis found in London Altars are the places where people had an opportunity to worship outdoor. There were numerous inscriptions on the altars which named the God or Gods to whom they were sacred. The inscriptions consisted of short sentences and had abbreviations. For example, V.S.L.M. Votum solvit libens merito which means He fulfills his vow, willingly, dutifully. (FrereTomlin, 1991) Archaeological examples of altars in the towns of Roman Britain are the following: Altar to Mother Goddesses of the household by Gaius Julius Crescens, Nunnely Lane which is situated in York Altars to Fortuna, Aesculapius, Salus and Genius Loci which is located in Chester The altar which commemorates the rebuilding of the temple of Isis by Marcus Martianius Pulcher located in London Our knowledge of Christianity in the Romano-British Period is taken mainly from the literary sources. So, the archaeological examples are scarce. The only one is a Christian Church which is situated at Silchester. It was a very small building in the center of the town that means the Christian Community had no local influence. RURAL RELIGION IN THE ROMANO-BRITISH PERIOD It is known that most people in Roman Britain lived in the country side. They lived in small villages. Those who were rich built large houses in a Roman style which were called villas. (Persival, 1976) Fig.4 Reconstruction Illustration of Bignor Villa in Sussex. A villa is a large beautiful house in a roman style which has tall stone walls and fabulous mosaic floors, with a bath house and gardens.(see fig.4,5) Fig.5 View of Rockbourne Villa (Hampshire). Country Council Museum. Rural religion included religious festivals when the peasants prayed to the Gods and Goddesses for having good harvest and healthy domestic animals. (see fig.6) It was very important for agriculture in the country side. It is impossible to find some written sources about the rural religion in life in the works of British writers. Fig.6 Mosaic which shows Ceres, the Goddess of Harvest. From Broading Villa. All the data concerning the rural life we can get from the archaeological excavations. The archaeologists found the remains of farm and villa buildings, the bones of domestic cattle, seeds of crops. There are two well-known villas in Roman Britain: Chedworth situated in Gloucestershire and Bignur which is situated in Sussex. (Salway, 1993) Fig.7 Map of town and regions of Roman Britain The most important religious festivals took place each season of the year. The festival of Lupercalia celebrated in the middle of February was devoted to springs awakening. The God Pan at Lupercalia or Faunus defended domestic animals (caws and sheep) and the shepherds. (Salway, 1993) The first Christians in the country-sides of Roman Britain persecuted that is why they worshiped in houses they lived. According to some archaeological data, Lullingstone Villa had the walls of a private chapel with pictures of people who were praying. (Hening, 1984) Fig.8 The Wall picture from the Christian Chapel in Lullingstone Villa, which shows people at prayer. The British Museum The archaeologists found a mosaic at a villa in Dorset which showed Jesus Christ with a symbol chi-rho behind his head. The orange fruits stand for the symbol of plenty. (see fig.9) Fig.9 The head of Jesus Christ painted on a mosaic from the villa at Hintin St.Mary in Dorset. The British Museum The archaeologists found a lead tank of the 4-th century from Walesby in Lincolnshire. It proves the fact that in order to become a member of the Christian Community it is necessary to be baptised with water by a priest. (see fig.10) Fig.10 A small part of a lead tank from Walesby which was used for Christian Baptism which shows people who are preparing for a babtism. City and Country Museum in Lincoln. The other interesting archaeological finding represents Roman silver vessels and spoons used in communion service.(see fig.11) Holy Communion is a significant part of Christian worship in with the members of the community believe that the priest must change wine and bread into Jesus Christ blood. (Millet, 1990) Fig.11 Church plate and silver vessels found in Water Newton, Cambridgeshire, the 4th century. The British Museum. Christians began to built churches in the 4th century. It is known that they had an apse which represented a small semi-circular area at the east part where the altar was located. (see fig.12) Fig.12 Reconstruction illustration of a Roman Church in Colchester. The apse is at the end of the building. Illustration be Peter Foster. Colchester Archaeological Trust CONCLUSION In the Roman Britain towns played an important role. They were the centers of trade, culture and government. It is known that in Britain before the Romans rule there were no towns or cities. All the towns were built by the Romans in different parts of Britain. For example, such towns as Colchester, Gloucester and Lincoln were built instead of legionary fortresses. The retired soldiers lived there. The towns in Roman Britain were not large (about 10000 people). Religion in the towns and cities of Roman Britain was more idealized than in the country-side. The temples were built mostly in the towns. Speaking about the villages in Roman Britain, it is necessary to say that rural religion was represented by the local culture and worship saved from the Iron Age. Rural religion fell behind urban religion. Moreover, there was a great difference in language too. In some remote mountainous regions, the people spoke Celtic language while in the towns the soldiers and traders spoke Latin. Nevert heless, rural religion which was mostly Pagan religion, later could be replaced by the Christianity. The above mentioned archaeological examples prove the obvious growth of Christian elements in the life of country-side in Romano-British period.

Gender Identity Essay -- Sociology, Gender Scheme Theory

The development of gender awareness is fundamental for our sense of self and is also predominant in any assessment made of another person as from birth on people respond differently to males and females. Gender identity can be seen as one of the earliest social categories that children learn to apply to both themselves and other people. This is suggested in Schaffer’s (1996) definition where gender identity is the correct labelling of self and others as male or female. There are three main theories that have been explored which all suggest multiple ways in which gender awareness is developed: Bandura, Kohlburg and the Gender Scheme Theory. Firstly, Bandura (1977) notes that the idea that social influences clearly plays a very significant role in the development of gender identity. Socialization makes children aware that there are differences between male and female, and that these sex differences matter. These social pressures also suggest there are specific gender stereotypes that they are expected to conform to. Nevertheless, it can also be seen that biological and cultural changes interact with these social factors, thus defining how an individual eventually develops the gender identity of a man or a woman. An alternative theory, expressed by Kohlburg (1966), suggests that children are not the recipients of any physical information from social experiences and therefore they search for specific regulations which will explain the way in which males and females are expected to behave. In addition, gender tends to be the first thing a parent wishes to find about their child. It can be suggested that from then on the child will be treated depending on the fact that they are male or female. This is shown in research attempting to cla... ... both masculine and feminine toys. Generally, parents gave positive responses to their pre-school children when they chose same-sex toys but negatively to cross-sex toys, thereby reinforcing their children’s sex role differentiation. On the other hand, according to Fagot (1985), sex-differentiation like that viewed in the previous study was not found in the teachers in charge of a group of 2 year olds. In this study, it was the children themselves who gave their peers engaging in sex-appropriate behaviour positive feedback of one kind or another. Again, boys were more likely to be disapproved of for ‘girly’ behaviour and were thus quickly given the chance of learning what is not male and so encouraging them to drop those behaviours or activities in their repertoire. Nevertheless, there are criticisms of these ‘social influence theories’ on sex role development.

Erp as Software as a Service (Saas) for Smes

ERP as Software as a Service *(*SaaS*)* for SMEs Table of Contents Page Abstract The main barriers for implementing ERP systems in SMEs were constraints in terms of resources and information, implementation time escalations, poorly defined organisational structures, weak formalisation of procedures or processes, unclear and also confused understanding amongst the employees and management. There are various methods to overcome the barriers of implementing ERP solutions in SMEs. This include coming up with a realistic value-adding processes required to be incorporated in the proposed ERP system, providing effective education on ERP systems, making sure as a vendors, they do not just provide lip service and to involve everyone in the whole system’s lifecycle. Software-as-a-service (SaaS) is an online delivery of softwares (Dubey & Wagle 2007). The model is uncomplicated and appealing wherein companies signs up to the use the solution which is hosted by the vendors that sells and/or develops the software rather than spending large sums on an application such as ERP and Customer Relationship Management (CRM) and installing this software on individual machines (Dubey & Wagle 2007; Banham 2008). All of the major software vendors are now offering its solution on SaaS model basis – SAP, Microsoft, IBM, Oracle and Salesforce. com are all staking their claims. Introduction SME Definition â€Å"companies with less than 250 employees, total assets under 27 million Euros,_ independent privately held_ and _ _owner-managers or their families manage the company personally (Loecher 2000; Sogorb 2002)†. _ Why ERP vendors are focusing on SME’s Barriers to implementation of ERP systems in SME’s It was found that the main barriers for implementing ERP systems in SMEs were: constraints in terms of resources and inf ormation, implementation time escalations, poorly defined organisational framework, informal and also non-orderly procedures or processes, unclear and also confused understanding amongst the employees and management. Each of these factors is now discussed in turn. _Figure 1: ERP implementation issues (source: Bernroider & Leseure 2005)_ How ERP vendors can overcome these barriers SaaS Technology Some other advantages of working with SaaS models include: low introduction and subscription costs and faster initiating speed (Kaplan 2005; Torbacki 2008), elimination of license and upgrade costs (Torbacki 2008), predictability of costs (Torbacki 2008), ow TCO costs (Total Cost of Ownership) due to lack of necessity of major investments in servers, databases and maintenance (Torbacki 2008), generating a greater ROI than traditional software packages (Kaplan 2005) no requirement of installing any software on a workstation (Torbacki 2008), online access from any location with an Internet connection (Torbacki 2008), continuous opportunity to the newest software versions and business technologies (Torbacki 2008), customers no longer require the large support staff for applications (Bontis & Chung 2000; Kapl an 2005) {draw:frame} Figure 2: Types of SaaS used or considering of using (source: Kaplan 2009)_ An example of one vendor’s SaaS offering Nationwide Express Farwest Steel Corporation SaaS alternatives have become more pervasive and observed fast development, and their cost-effectiveness, operational reliability become more obvious and there are a growing number of enterprises of all sizes that are generating performance improvements and measurable cost savings as a result of adopting SaaS. For SaaS vendors, they must focus on make possible easier deployments to avoid the need for pricey consultation support. Also they should truly deliver lower total cost of ownership (TCO) and offer more robust strategies for integration that acknowledges the current volatile environments and also in the near future. Finally, the SaaS solutions offered must be simpler, more agile, more robust, and more intuitive and worthy of all the investments allocated.

Black Hawk Down Essay

The name Black Hawk Down used as the title of this book in our context originated from the helicopter (UH-60 Black Hawk) used during the raid in Mogadishu. This raid is said to be one of the most combative war Americans have ever engaged in from that of Vietnam. The mission took place in October 1993 when helicopters dropped American solders in the heart of Mogadishu with aim of abducting top lieutenants of Somalia Warlord Mohamed Farrah Aidid. This was under leadership of Thomas Matthews who was deployed in Mogadishu, he lead Task force Ranger. This war was referred to as Operative Gothic serpent although it was later referred to as Battle of Mogadishu by international opposed media to this battle. â€Å"The most significant combat action took place on October 3, when Task Force Ranger captured six of Aideed’s [sic] lieutenants and several militiamen in a daylight raid. During withdrawal operations, the Somalis shot down two UH-60 helicopters and U. S. forces remaining on the ground came under heavy fire as they attempted to carry out rescue operations and consolidate their positions† (Spiller, para 4). This episode translated to intense fire fight which saw about 300 Somali nationals killed and others seriously injured. On the side of Ranger several were killed and others wounded before intervention of Pakistan and Malaysia intervened hence withdrawal of the forces. The story on modern war by Mark Bowden, a report with the Philadelphia inquire tries to analyze battle of Mogadishu which started with attempts of the American solder to capture aides to Aidid. The operation strayed with Delta force personnel through help of US army Rangers entered Mogadishu through helicopters to start the operation. This entry surprised Somali who were not were not aware of this mission. This called for rehearsal for using grenade and was successfully able to bring chopper down hence there capability in fighting new enemies invading their soil. The shooting of Back hawk helicopters through use of grenade formed a battle field where the American fought frantically to ensure they salvage there comrades. In his book Bowden tries to give a narrative of this war through reconstruction of the materials he was able to get through intensive interviews to the participants of this war. In his story he divert from the notion military history which always portrays glory of war without disclosing episode of horror which always engulf these kind of wars. Black hawk down story is literally distinctive in its style and this can be attributed to the fact that Bowden is a journalist but not a historian and writes his description of the combat as a tale, relatively like a fiction story. This book is set to represent the actual event and happening of the battle of Mogadishu. Bowden accomplished this through widespread research, consultations with accomplices from the two sides of the conflicts; this is also done through help of footage recorded by aerial observation aircraft at the fight as well as from recordings of the radio traffic from the clash. This book represent a parable of leadership which was unable to control the discipline of military personnel giving a picture of failure of the so perceived as strongest army in world. This is because military was unable to contain undisciplined militia putting the most powerful military in a precarious circumstances. The author demonstrates a situation of overconfidence since American military from the word go never expected the situation can in any way go against them. On the side of Rangers and delta forces soldiers in Mogadishu battle has elaborated as failure. The leadership controlling the war to command daylight raid has been describe as failure in military point of view. This raid on the side of America army cannot boost of victory since the only achievement attained was only seizing and imprisoning Somali clan officials who part of the mission of the war. In return to this achievement, a body of dead American member of Ranger squad being drugged in the street watering small achievement realized before the massacre. Mogadishu Massacre was motivated by the silencing of Somali warlord Mohamed Farrah Aidid who was wrongly perceived to have Hitler like trait, and was said to be responsible for thousands of brutal killings. There was information that this warlord ruled Mogadishu and hijacked UN food shipment acting in aid of war causalities. Aidid was also accuse of waiting the US Marine withdrawal and declaring war on U. N. forces ensnaring and killing of Pakistan peacekeepers. This is the incident which translated to sending of Ranger on mission to dismantle advancement of Aidid and ensure restoration of order within Mogadishu and its environs. This was meant to stop Aidid force from disruption of Red Cross distribution centre and killing of innocent civilians. Aidid was a powerful leader of Habr Gidr a large clan with political control within Mogadishu which controlled past as well as present political activities in this region. â€Å"The Habr Gidr were the militarily more powerful of two main groups contending for control of Mogadishu. If the U. S. had killed Aidid, citizens of the Habr Gidr areas wouldn’t generally have felt liberated, like Afghans freed from the Taliban† (Kaus, 2002 para 6). This book highlights phases of US and UN activities in Somalia. Firstly there was humanitarian phase where unite nations use military for to ease deliveries of food with aim of controlling deaths which could have emanated from starvation. This initiative was carried beyond from provision of food to the nation building mission in Somalia by UN. National building can be termed as the second phase with ambitions of restoration of entire country. From the ambitious mission of rebuilding entire Somali country Aidid claimed of UN official being against his and his clan of the said links with the former Somali dictator Siad Barre who was Aidid rival. From these suspicions intimidation of nation building started from the Aidid and his clan making effort to be at risk. National building needed very conducive peaceful environment from all clans and when Aidid intimidation started meant sinking of the national building efforts. Conference to forge for peace were staged but what followed after that was lack of peace deal and Aidid stepped up mission of detaining there rival something viewed by UN as intention to intimidate the peace talk. Attempt to marginalize Aidid politically by UN followed something viewed as a wrong approach to someone who had a backing of entire clan behind him. This is because to realize peace in this situation a better approach could have been employed to ensure existing military structure and power are dismantled or contained. This was followed by attempt of UN tying to shut down Aidid radio which was popular in propagating anti-UN propaganda a fact which made Aidid to see UN being against him. This is the issue which translated to the Mogadishu war from the attempt of UN tying to kill Habr Gidr clan member. After this was the incident of Black hawk down and translated to killings of innocent civilian an army leadership which has been greatly blamed for failed victory. â€Å"Crisis leadership came the hard way for U. S. Army Colonel Thomas Matthews, who led the Task Force Ranger mission in Mogadishu, Somalia in 1993† (Lagace, para 1). The situation in Mogadishu Massacre called for life or death decisions which were to be guided by Thomas leadership. This is the leadership which has been condemned for failed success in the ranger mission. The decision made by Thomas on this day resulted to crisis witnessed in this episode making a good lesson for our leadership decision especially in the army forces where decision with dire consequence are made.
