Spanking And Its Effect On Children - 773 Words

ALIDITY AND RELIABILITY 2 Spanking as a way to punish children is a heated debate that does not appear to have an end in sight. The people on both sides of the issue have very strong opinions and do not seem to want to entertain the idea that the other side could be correct. This is generally how debates work, but one concern that is often not looked at is whether the claims from either side are valid and reliable. Anyone can make claims and find evidence for those claims, but the evidence may not be sound and therefore not useful. If we want our arguments to mean something we need to use evidence that is both valid and reliable. Lee et al. argue that spanking can lead to increased aggression in children ages one to five. They set out to determine if there is a correlation between maternal warmth and spanking in regards to childhood aggression (Lee). While I think this study is a great start to research on spanking and aggression, the methods are far from perfect. Thi s has an effect on the overall reliability and validity of the research and the impact of the findings. The participants (mothers only) in this study also participated the in Fragile Families and Child Wellbeing Study (FFCWS). The authors admit that using participants who were also involved in the FFCWS study meant that they were getting an over-represented of self identified black (49%) and Hispanic (26%) mothers (Lee).

Growing up Asian in Australia-Free-Samples-Samples for Students

Question: Write a Literature Review on Growing up Asian in Australia. Answer: Conversation with My Parents by Oanh Thi Tran Communication is an integral part of life. Communicating information, ideas, thoughts, emotions are a part of life that is important because it helps an individual to lead a life that is fulfilling. Another significant part of a persons life is family. Family does not have to be necessarily be parents or related by blood; the people who are close to an individual can also be associated with family. In this short story the author tries to bind the two topics together on the same line. She tries to state the significance of conversation with the family and how it affects the life of an individual. The author did not have a very healthy relationship with her family and parents, she was always aloof and felt distant form them and hence after growing up she had decided to move to England. It was not until that her father was admitted to the hospital did she actually have a proper conversation with her parents. Telephonic conversations can be a little tricky as the communication is not happening face to face it is a little difficult to understand what a person is trying to say or trying to hide in the expressions (Pung, 2008). Oanh started talking with her father over the phone regularly after he was admitted to the hospital. He spoke about his childhood days and she enjoyed them thoroughly. Though the first conversation was drab stretched and boring as the she had not spoken with her parents for a really long time. The next one was with her niece and that broke the ice in between the family and her. Hence the calls continued, but then by the end of the story Oanh could not express her feeling and love for her parents because she still feels the hesitation which will not b solved by just telephonic conversations (Pung, 2008). Anzac Day by James Chong Growing up in a different country has always been a challenging affair for a child especially for the ones who come from a different ethnicity. There have been several incidents where people have faced bulling, biased behavior; stereotyping and even judgmental outlooks form various sectors of life. But the story of James Chong has a different perspective and a different issue all together. In this story he doesnt talk about what he has gone through in his entire life. He states an incident that broke his heart. The story is about how Chong was questioned about his patriotism when he was just a high school child by the national media. Chong was in the school band and played the bag pier, he was selected to play I the band on the converted Anzac Day. Anzac Day is regarded as one of the most patriotic and symbolically proud day for the Australian public. Like every other fellow student he also felt the same for his country and he was more than happy to be part of such a grand affair of the country. But he was struck by a feeling of exclusion, separation and abandonees when he found his image on the national media and the theme of discussion was True Blue? (Pung, 2008). Anh Do Famed by his stints from popular Australian television programs such as thank god you are here and dancing with the stars, the Vietnamese-Australian is now a popular name in Australian television. His ease and his non imposed easy humor was his claim to fame. He was also awarded the comedian of the year. In his interview he had mentioned that growing up he wanted to be a martial art champion because he thought it was cool, but he was witty and humor was always his calling the way he answered the coach of the jujitsu class was effortlessly funny. He readily accepted that he is a lazy person and that is the reason why he had opted for a change in career. He could not believe the sixty working hour schedule and he wanted to laze. He was offered 50 dollars for five minutes and that prospect excited him that he was making a dollar a minute but then it was five minutes a week and he continued it for six months. Anh Do is a witty and intelligent man and that is evident from the way he answers the question. He gives an example of his gig where he was caught up in between the comrades of martyrs who were killed by Asians. He describes it as a hard gig. He is of the view that the destination is secondary what people needs to focus on is the journey (Pung, 2008). Reference list: Pung, A. (Ed.). (2008).Growing up Asian in Australia. Black Inc..

The most frequently heard term in the Human Resource management is layoffs and restructuring. Downsizing being one of the form of such employee cutting have many faces of its effect on the corporate values. So the current study tries to understand the overview of downsizing and the HR skills required to execute down sizing in an organization. Also the study tries to analyze the good and bad forms of the concept down sizing under the section by taking the concerns of rightsizing and dumb sizing. What is Down Sizing Downsizing: Downsizing is kind of organizational restructuring. The term is mostly used when organization adopts a workforce reduction. Downsizing or Workforce Reduction: According to Steven Applebaum and his colleagues (1987) as cited in Alexis A. Halley refers the definition of term downsizing as coined to define the scaling down of car sizes by automobile manufacturers. However the term was adopted to HR field in cutting down the employees during 1980s. Downsizing is a strategy to resize, streamline and shrink the organizational structure with respect to employee number. Usually it is assumed that companies down size people to restructure their existing employees by number wise. However, Restructuring can also be defined as rebuilding the strength of an organization by changing its asset structure and its resource allocation patterns (see Hoskisson Hitt, 1994). Why Use Downsizing: Companies mainly during the period of recession, try to increase the costs in many possible ways. One among those quick fixes is cost cutting through Employee layoff.

But repeated usage of the tool can result in the erosion of the human capital. Role of HR in Downsizing: The HR should play a vital role in cutting back the employees, yet retaining the life blood of the company. A company needs some employees in key positions with required skill set to be adhered to their competitive responsibilities all the time. HR need to identify which skill set or professionals to be retained during the period to void disturbance in the existing process. Also the HR should take care of the effort load of the removed employees which ultimately falls on the retained employees due to the cut down on employees. The major challenge for HR in such circumstances is to deal with the remaining employee morale. The employee security becomes shattered and HR has to affirm them of their position in the organization. For this the HR should be communicative with management a well with the employees in getting their concern and feedback from time to time. Also the HR should assist management in planning the downsizing in an approached way. There are different approaches and tools available to the HR to perform the Downsize efficiently and in a strategic way. Downsizing is a kind of change adoption. Change is observed in two ways: The Incremental Approach: This approach starts with denial of wrong followed by patching and crisis and then by rightsizing. However, this approach may create tension and anxiety in the organization. The phases and events are unpredictable in this approach. 2. The strategic approach: This approach involves rethinking, and searches for new mental maps and new tools. The strategic approach though lengthy results profitable in long run.

Reagan and the 1983 Marines Barracks Massacre in Beirut

Reagan and the 1983 Marines Barracks Massacre in Beirut In 2002, the Presidential Oral History Program at the University of Virginia’s Miller Center of Public Affairs interviewed Caspar Weinberger about the six years (1981-1987) he spent as Ronald Reagan’s Secretary of Defense. Stephen Knott, the interviewer, asked him about the bombing of the U.S. Marines barracks in Beirut on Oct. 23, 1983, which killed 241 Marines. Here’s his answer: Weinberger: Well, that’s one of my saddest memories. I was not persuasive enough to persuade the President that the Marines were there on an impossible mission. They were very lightly armed. They were not permitted to take the high ground in front of them or the flanks on either side. They had no mission except to sit at the airport, which is just like sitting in a bull’s eye. Theoretically, their presence was supposed to support the idea of disengagement and ultimate peace. I said, â€Å"They’re in a position of extraordinary danger. They have no mission. They have no capability of carrying out a mission, and they’re terribly vulnerable.† It didn’t take any gift of prophecy or anything to see how vulnerable they were. When that horrible tragedy came, why, as I say, I took it very personally and still feel responsible in not having been persuasive enough to overcome the arguments that â€Å"Marines don’t cut and run,† and â€Å"We can’t leave because we’re there,† and all of that. I begged the President at least to pull them back and put them back on their transports as a more defensible position. That ultimately, of course, was done after the tragedy. Knott also asked Weinberger about â€Å"the impact that the tragedy had on President Reagan.† Weinberger: Well, it was very, very marked, there was no question about it. And it couldn’t have come at a worse time. We were planning that very weekend for the actions in Grenada to overcome the anarchy that was down there and the potential seizure of American students, and all the memories of the Iranian hostages. We had planned that for Monday morning, and this terrible event occurred on Saturday night. Yes, it had a very deep effect. We talked a few minutes ago about the strategic defense. One of the other things that had a tremendous effect on him was the necessity of playing these war games and rehearsing, in which we went over the role of the President. The standard scenario was that â€Å"the Soviets had launched a missile. You have eighteen minutes, Mr. President. What are we going to do?† He said, â€Å"Almost any target we attack will have huge collateral damage.† Collateral damage is the polite way of phrasing the number of innocent women and children who are killed because you’re engaging in a war, and it was up in the hundreds of thousands. That is one of the things, I think, that convinced him that we not only had to have a strategic defense, but we should offer to share it. That was another of the things that was quite unusual about our acquiring strategic defense, and which now seems largely forgotten. When we got it, we said he would share it with the world, so as to render all of these weapons useless. He insisted on that kind of proposal. And as it turned out, with this cold war ending and all, it didn’t become necessary. One thing that disappointed him most was the reaction of the academic and the so-called defense expert community to this proposal. They were horrified. They threw up their hands. It was worse than talking about evil empire. Here you were undermining the years and years of academic discipline that you shouldn’t have any defense. He said he simply did not want to trust the future of the world to philosophic assumptions. And all the evidence was that the Soviets were preparing for a nuclear war. They had these huge underground cities and underground communications. They were setting up environments in which they could live for a long time and keep their command and control communications capabilities. But people didn’t want to believe that and therefore didn’t believe it. Read the full interview at the Miller Center for Public Affairs.

Hw2 Essay Example | Topics and Well Written Essays - 500 words - 1

Hw2 - Essay Example Bacteria have the ability to develop resistance to antibiotics making the use of such drugs ineffective. Antibiotics resistance is a situation whereby an antimicrobial drug ceases to have effect in stopping or killing such microorganisms. Refereeing to antimicrobial, they are substance, both natural and synthetic as well as disinfectants that have the ability to kill or hindering the reproduction of microorganisms. Before the antibiotic drugs were discovered in the 1940s, there were many deaths arising from sexually transmitted diseases and infections such as tuberculosis. The new drugs enabled the fighting of the diseases possible, however, over time; some of the germs have developed resistance to the drugs. The most common causes are the inappropriate use or overuse of drugs such as antibiotics in the treatment of people and animals. The germs continuously adapt to their environments and have the ability to develop the characteristics that are similar to those of others. In using antibiotics, only the weak bacteria are killed while the stronger and more resistant ones survive and continue to multiply. Any germ that successfully develops resistance to a particular drug has the potential of developing resistance to other antibiotics as well, referred to as cross-resistance. There has also been developed a link between the administering of drugs to animals the development of resistance in humans. Often, the food producing animals are administered some drugs so as to prevent infections and boost food production in the agri-food industry. Even the products of plants also get into contact with the chemicals when sprayed to help in the control of or preventing diseases. Through this, the resistance problem is transferred to the products such as milk and fruits. The most common example is Salmonella that can be transferred

Benihana of Tokyo Case Study Example | Topics and Well Written Essays - 500 words

Benihana of Tokyo - Case Study Example However, a market research done by Rocky, the president of this hotel, pointed otherwise. Through this research, Rocky realized that many Americans do not trust meals that are prepared in enclosures that are not visible for the customer. Therefore, he ensured that the meals, especially the streak were prepared from a close proximity to the dining table so that customers would be in a position to watch as their meals are being prepared. This boosted the trust of the customers towards the firm. Unlike other typical restaurants which have 30% of their total space as back of the house, this restaurant has only 22% of the total space left as back of the house (Warner 34). This has increased the space available for the restaurant. Another factor that distinguished this restaurant from others within this locality was the fact that its chefs were all from the parent country, Japan. All of them were young unmarried individuals with high standards of training in hospitality industry. The mannerism of the restaurant, though American in all aspects, had a touch of the Japanese culture, a fact that made it stand out as uniquely cultural. Simply put, the operation of this restaurant is positively unique. The design choices of this restaurant have positive contributions to the general operative efficiencies. The decision to have the cooking area located close to the dining hall is not only meant to please the customers as they watch their meals being prepared, but it also enhances the efficiency. The cooking area is very close to the customers and therefore the process of serving is easier. As the president of this restaurant admits, this has enabled the management to cut down on the operative cost because it would require a relatively lesser labor as compared to a conventional kitchen location in typical hotels (Page 76). The decision to reduce the back space of the hotel has also improved efficiency of

Emerging Market Firms vs Multinational Corporations

Emerging Market Firms vs Multinational Corporations A fresh breed of determined MNC is intensifying on the world, presenting both opportunities and challenges for conventional and well established multinationals. These new competitors hail from apparently unlikely places, emerging countries such as China, Russia, Brazil, India and even Indonesia and South Africa. They are vibrating the entire industries, from automobile and electronics to information technology and telecom services, and altering the systems of global competition. (Business Week, 2006, p. 42). 21st century has carried away with several new opportunities and challenges due to the events and improvements in the recent past. The impact of these developments is felt more on the developing countries as these rapidly progress in terms of financial and market growth therefore getting closer to the emerging markets. Developing countries such as China, India, Indonesia and Brazil play an important role in the world economy, entrepreneurs and corporate companies in these emerging markets are aiming to build a world class and internationalised firms. The main ambition of these Emerging Giants is to make the most of new opportunities and to be able to compete against international MNCs. So it is increasingly essential for the firms in emerging markets to get a clear understanding of these market opportunities and challenges to succeed in todays global economy. A clear picture of the current state affairs shows that though firms have been rigorously smacked by the economic crisis and t he drop in demand, the most of emerging firms have, so far, endured the test and prevented the collapse of their recently built international structures. However, there are a rising set of firms that appear to challenge these odds, and score stunning successes in their battles against MNCs. These firms, so called Emerging Giants, offer some imperative stuff in how emerging markets can craft endearing approaches. This report provides a general framework for developing world-class firms from emerging economies and the challenges and opportunities faced by these firms to become an Emerging Giants. Shock Opportunities faced by firms in emerging markets: Nowadays, many firms from emerging economies are making the world astonish and become very familiar. For the past two decades, waves of globalisation have removed protectionist hurdles in the emerging markets. A foreign competitive pressure started to flow through the world economy, from firms in emerging economies like India, China, Brazil and Russia. These firms are looking to become world class global players just as Tata Steel rose from India and Sony emerged from Japan in earlier stages of globalisation. Once these emerging economies entered themselves into the world economy, multinational enterprises from Europe, America, Korea, and Japan were assaulted. Many domestic firms lost the market share and forced to shed off their businesses. However, a few organisations battled hard and survived. They held their own businesses against the blitz, restructured their organisations, utilized new opportunities, and developed international companies that made their global rivals astonish and made them think. Challenges faced by emerging market firms: Whilst companies from the emerging economies continue with their expansion of international business, they are faced with an enduring issue are they capable to manage their accumulated assets economically on a global scale. Emerging firms are facing many challenges particularly due to inappropriate organizational structure, talent shortage, cultural differences, and lack experience in international business management. While facing specific challenges in various sectors and industries, emerging giants often come across common difficulties. One key issue about this dominance is that MNCs may use their supremacy and influence to interfere in the host governments finance, economic and political policies for their own growth (Harrison, Dalkiran, Elsey, 2000). The significant challenge for these emerging companies is to successfully compete with MNCs which have two fundamental advantages over emerging economy firms. First challenge is MNCs are well conventional, and hence have advantages of incumbency: Reputation, infrastructure, brand image, latest technology, organisational structure and access to vast resource funding, contacts, distribution network and supplier (Malchow Moller, N., Markusen, 2007). But firms from emerging markets do not have these advantages in order to compete against the multinationals. The worst part is that they come from economies that experience severe market breakdown. They lack the infrastructure and HRM that makes a multinational firm. With developed markets getting increasingly saturated, Multinational enterprises (MNEs) are trying to expand their business globally. Global businesses have enormously increasing due to fact that decreasing of barriers in the international trading. Because of this fact most of the multinational enterprises storming in to emerging economies in order take the advantage of the conditions and opportunities for future growth. Local consumers have a wider choice after the arrival of multinational corporations . As a result local firms from emerging markets are left with very fewer opportunities and the influx will restrict the emerging firms growth. When emerging economies open-up, local firms are forced to fight against MNCs with their poor economy and hence they cannot invest more in RD, advertising and marketing which are some of the essential aspects in order to compete with multinational enterprises. They are also in the back foot due to meagre infrastructure, supply and distribution network. Even while emerging companies are able to evade some of these obstacles and settle on a path of rapid development, they are hindered by the low domestic management talent group in their attempts t o develop a world class organisation. In theory, emerging firms can triumph over some of these barriers by accessing global markets for technology, finance and talent (Lipsey, 2002.). However, in prevailing conditions, different rigid and reputational obstacles often make this choice difficult to implement. Because of this reason, management in emerging economies are evidently worried about being thrown out in their domestic market by MNCs wh en their domestic markets provide space to global competition. Last 2 decades have seen a wave of countries opening up to the world economy; the challenge for potential emerging giants is more extreme than before. Competing against MNCs: Multinational firms from developed markets have an imperative advantage over emerging economies firms-access to the excellent organisational infrastructure. For example, U.K. MNCs have access to the British financial markets, which eases them to raise low-cost finance structures in great quantity. They have world-class talent available through a well-built white-collar labour market and also they could able to develop good quality products using Research development centres, marketing and advertising techniques. They are ahead of firms from developing countries with latest and advanced technologies developed by pioneering firms. Having all these advantages, wouldnt Firms from developed countries make use of business opportunities in emerging economies better than the emerging economy firms themselves? However, emerging market firms have a significant advantage over the firms from international companies. There are some reasons why firms from emerging economy can potentially turn the disadvantage of functioning in an emerging economy into an advantage, and may counteract the incumbency benefit of MNCs in terms of their technology, brand image and access to capital. First, sophisticated market MNCs looking to take advantage of business opportunities in developing markets are faced with some challenges that emerging market firms have to contend with. For example, firms from developed countries look to exploit professional talent in emerging market. However, the firm has to deal with the excellence uncertainty in the labour market, and learn ways to find skilled professional to serve global market needs. It also has to study to operate with poorly built infrastructure. Emerging economy manufacturers have a distinct advantage over foreign MNEs in dealing with local institutional voids for example-they have significant experience and cultural knowledge in dealing with these issues. In fact, MNCs managers, spent their years of experience with a well-built infrastructure, are often are unable to deal with institutional issues that make it difficult to access consistent market information, and/or configure business partnerships based on trustworthy con tracts. Emerging economies businesses, in contrast, have extensive knowledge of these institutional voids, and are able to manage them around through relaxed collective mechanisms and a deep knowledge with their environment. Second, MNCs are often hesitant to tailor their commodities and distribute them to each country that they function in. This is especially true for western MNCs with a very successful business in large sophisticated markets in Northern and Western Europe. For these firms, it is too expensive and big headache to alter their goods and services to suit distinctive behaviour just to make use of what they see as risky and small business prospects in emerging economies. Their cost structure is also an important factor because it will be difficult for them to manufacture goods at price which is optimal for emerging markets. Firms in emerging markets, in contrast, have advantage over these constraints.
