Compare the scandal involving President Clinton with Nixon's Research Paper

Compare the scandal involving President Clinton with Nixon's Watergate. What were the key similarities and differences - Research Paper Example In June 1995, a scandal began during the latter half of his second term involving Monica Lewinsky, 21, who came to the White House as an unpaid intern in the office of White House Chief of Staff, Leon Panetta. In November 1995, she got involved in a sexual relationship with President Clinton. Barely a month into the relationship, Lewinsky was moved to a paid position in the Office of Legislative Affairs, handling letters from members of Congress. She frequently ferried mail to the Oval Office. Around April, 1996, Lewinsky was transferred to a job as an assistant to Pentagon spokesman Ken Bacon, by Evelyn Lieberman who was then the Deputy White House Chief of Staff. Lieberman told the New York Times later that the move was due to â€Å"inappropriate and immature behavior† and that Lewinsky demonstrated a lack of attention to work. At the Pentagon, Lewinsky met Linda Tripp, a career government employee. Around summer 1996, Lewinsky began telling Tripp during casual conversations about her relationship with President Clinton. Tripp reported these conversations to literary agent Lucianne Goldberg, who advised her to secretly record them. Tripp convinced Lewinsky to save the gifts she received from the President and the dress that got stained during one of her sexual encounters. About a year later, in the fall of 1997, when the relationship was over, Tripp secretly began taping the conversations with Lewinsky in which she explicitly talked about her alleged affair. Around October 1997, Tripp, with help from Lucianne Goldberg, met with Newsweek’s Michael Isikoff, Kucianne & Jonah Goldberg at Jonah’s apartment in Washington, where they listened to a tape with the Tripp/Lewinsky conversation. In October 1997, Lewinsky interviewed with U.S. Ambassador to the U.N., Bill Richardson for a low level public affairs position in New York. She was offered a job but she declined. In early December that year, Lewinsky left the Pentagon. Later that month, Bett ie Currie, President Clinton’s personal secretary, got in touch with Vernon Jordan, a friend of Clintons, to place Lewinsky in New York. Vernon Jordan obliged and introduced Lewinsky to several leads. Lewinsky allegedly had over 9 sexual encounters with the President in the Oval Office during the period between November 1995 and March 1997. On December 17, 1997, Lewinsky was subpoenaed by lawyers for Paula Jones, who was suing the President on sexual harassment charges. She submitted an affidavit in which she declared that she never had any sexual relationship with the President. She also, allegedly attempted to persuade Tripp to lie under oath in the Jones case. Tripp, instead, gave the tapes to Kenneth Starr, who was the Independent Counsel investigating the Whitewater & Paula Jones case. Lewinsky made her final visit to the White House on December 28, 1997, when she and the President had a private meeting. During this meeting, the President allegedly encouraged Lewinsky to be as evasive as possible in her responses to any of the questions in the Jones’ lawsuit. On January 16th 1998, Kenneth Starr contacted United States Attorney General, Janet Reno, seeking permission to expand his probe to investigate possible impropriety on the part of the President. The Attorney General gave her consent and submitted a request to a panel of three Federal judges. The judges agreed to allow Kenneth Starr to formally investigate the possibility of subornation of perjury and obstruction of justice

Hallstead Case Essay Example for Free

Hallstead Case Essay 1.)The breakeven point in number of sales has risen along with the breakeven point in sales dollars from 2003 to 2006. The margin of safety has decreased as well. Every year they have to increase the number of sales tickets then the previous year to meet their breakeven point. After 2004 when expansion of the store begun, Hallstead’s fixed cost have grown each year. The decrease from 2004 to 2006 is far less substantial than from 2003 to 2004. This damage is cause by the stores expansion. It is renting a much larger space down the street from its previous location. This has incurred much lager expenses each year then in than prior to 2004. 2.)Yes, the company’s income would increase. The new breakeven point in sales dollars would be approximately $6.03 million. 3.)Eliminating sales commission would have a huge effect on the breakeven volume. If they follow through with Gretchen’s idea of eliminating sales commission their expenses would decrease a great deal each year. They would not have to make nearly as many sales to breakeven. Although this could have an adverse effect on the sales volume. Employees will not be nearly as aggressive in making sales because it will not affect their personal income. Employees could act disapprovingly towards this new measure, affecting the bottom line negatively in the long run. 4.)If Hallstead added an additional $200,000 to advertising each year they would have to increase the sales volume considerably, that’s if they decide not to do away with sales commission. 5.)Average sales would have to increase over $24 to break even if fixed costs remained the same. 6.)I would recommend that Hallstead Jewelers listen to the consultant that suggested price reduction to increase sales. I believe this would be a smart move because with the new store they have room for more sales then the previous location so upping sales numbers is an important step. If reducing sales doesn’t help improve the bottom line, I would then suggest that they eliminate sales commission. Although this as been an important part of business, eliminating sales commission would greatly decrease their yearly expense. I think adding advertising after their recent move is extremely important. Although it is a $200,000 expense, it could increase sales significantly. These are my suggestions for Hallstead Jewelers

Y2K Bug :: essays research papers

Y2K – The Big Issue Abstract and Executive Overview What is the Y2K issue? This paper will describe the problems associated with Y2K and how Industry, Government, and Small Businesses are handling the problem. The first chapter introduces the Y2K issues. Chapter 2 will define how this affects the different businesses and Government agencies. Chapter 3 will develop an overall plan on how to attack the problem and recommendations. The majority of this paper will develop a plan on how each of the businesses and Government agencies should attack the Y2K problems. There should be a logical approach to planning how to investigate, test, validate, and if required, develop a contingency plan for Y2K. The job is to either form a team of personnel or hire a consulting firm to assess your situation. The team should employ the following steps: assess the system, renovate the system if necessary, validate the renovation if necessary, implement the renovation if necessary, test the renovation if necessary, and finally have a contingency plan in the event that renovating the system is not feasible and/or is too late. The only necessary or required action is to assess the system. This will be discussed in detail in my paper. The real issue is that less than a year remains before the year 2000 problems are here. The recommendation is to begin working this issue now. It may be too late, but that is when the contingency plan comes in handy. TABLE OF CONTENTS 1. What are the Y2K Issues? 2.

High School and School Counseling Interventions Essay

Introduction and rationale for the research In the fields of counseling, education, and psychology, there has been a strong emphasis placed on evidence-based practices to determine the effectiveness of school counseling interventions. In this article, two types of Meta-Analysis interventions were used during this study. Meta-Analysis 1 involved treatment-control comparisons and Meta-Analysis 2 involved pretest-posttest differences. The overall average weighted effect size for school counseling interventions was . 30. This study determined how effective moderator variables influenced effect size of, guidance curriculum, individual planning, responsive services, and system support. Analyses of moderator variables are designed to determine the effectiveness of school counseling program activities in this article. Major strengths/weaknesses in the article The overall school counseling interventions produced an average effect size of . 30 which is significant. However, in this article, the average effect size of Meta-Analysis 2 intervention was not significant, only . 07. Previously research has found that meta- analyses using pretest-posttest typically produces a higher effect size compared to the more traditional treatment-control group comparisons. It’s difficult to determine the non-significant mean effect size for pretest-posttest meta-analysis. Additional analyses in the pretest and posttest form will need to focus on specific interventions and additional information regarding the effectiveness of specific strategies in school counseling. One of the common criticism of meta-analytic approaches is that studies with weak methodological rigor may artificially inflate average effect sizes(M. W. Lipsey,2003). M. W. Lipsey (2003) also argued that methodological moderator variables that often are assumed to be independent are not necessarily independent and carefully conducted meta-analytic reviews should explore methodological relationship patterns. The effect size of . 30 was based on 117 experimental studies that involved 153 interventions, which is a significant increase from the six studies used by Sprinthall (1981). Many more studies were conducted with elementary school students; however, school counseling interventions included in this meta-analysis appeared to be slightly more effective with middle or junior high students followed by high school students. Thus, these studies show a significant effect on school counseling interventions for all levels of K-12 education. There are also some limitations when meta-analytic techniques are used. The validity of effect size largely depends on the quality of studies that were included in the review. Some major limitations in school counseling research could not be addressed statistically. Also there are few studies that address the issues of treatment integrity. Only a handful of studies used treatment manuals or well-developed curricula. It was difficult for researches to determine what was effective because researchers could not determine what interventions were implemented with students. Another limitation was the elimination of 111 studies that had insufficient data or missing information. Another limitation from this article concerns the dominance of non-standardized outcome assessments in school counseling research. Meta-analysis also lacked long-term follow-up data. The lack of longitudinal data allows for the measurement and analysis of only short-term effectiveness. Another issue with meta-analysis research is that interventions focused mostly on specific interventions rather than comprehensive school counseling programs. There has been very few research studies conducted on comprehensive school counseling programs. Summary of research outcome.  There were 118 studies that used meta-analysis 1, involving treatment-control comparisons and 153 school interventions; however, two studies were considered one study because of the same simple. Out of the 117 studies, 81 were published in journals and 36 were theses or dissertations. This meta-analysis study had 16,296 participants and the sample ranged from 8 to 5, 618, with the average study involving 139. 28 participants. From these studies, 50. 4% were elementary school students, 17. 9% were middle or junior high school students, and 24. 8% were high school students, and 6% had a mixture of ages, and one study did not report the age of the student participants. There was an overall weighted effect size of 27% for students that received school counseling intervention compared to those students that did not receive school counseling intervention. The average effect size was significant. Also, there were a total of 33studies that used meta-analysis 2, involving pretest-posttest design; however, two effect sizes were eliminated from one study. Therefore, 31 studies that involved 51 school counseling interventions were used. The effect sizes calculated from these 31 studies involved 2,015 participants and the average study involving 62. 97 students and the sample ranged from 9 to 283. Out of the 31 studies, 17 were published in journals, 13 were theses or dissertations, and one study was an ERIC document. From these studies, 29% involved elementary school students, 12. 9% were middle or junior high school students, and 54. 8% were high school students, and 3. 2% had a mixture of ages and grade levels. There was only a . 07% weighted effect size on pretest and posttest meta-analysis which indicates the average effect size was not significant. Two methods of applying this research to practice Firstly, my goal as an aspiring school counselor is to implement a comprehensive school counseling program for all students. I would provide a variety of interventions and activities using the four components of the delivery system of a school counseling program, guidance curriculum, individual student planning, responsive services, and system support. I would then, conduct studies in my school, collecting data, and determine which services students and the school will benefit from the most. This will help me determine what type of programs and activities are most effective for our students and school. Secondly, I would consider taking additional research courses to prepare me to contribute to the knowledge base of school counseling, while conducting research projects related to school counseling. Simply, there needs to be more and better research in the area of school counseling. â€Å"Without additional empirical support, some schools may eliminate professional school counseling programs†(Erford, p 68). Conclusion. From this research on meta-analyses not all school counseling interventions were equally effective. Additional research is needed to examine the impact these studies had on students from diverse backgrounds. Although more research is often a recommendation after completing a meta-analysis (e. g. , Ehri et al. , 2001; Swanson, 1999; Whiston, Brecheisen,& Stephens, 2003; Xin, Grasso, Dipipi-Hoy, & Jitendra, 2005), we contend that lack of methodological rigor and dearth of studies make the calls for additional sound research in school counseling particularly important. Also, the issues of treatment integrity and increasingly use standardized outcome assessments will enhance future school counseling interventions. From this study, one would learn that additional research is needed, however, from this research; data shows that school counseling interventions have a positive effect size on student outcomes. Furthermore, there were significant effect sizes for interventions at the elementary, middle, and high school levels. School counselors’ were able to increase students’ ability to solve problems while decreasing discipline problems. However, the researchers were unable to identify specific programs or approaches that produce positive outcomes. Additional research is needed to address what interventions for school counseling works, with what students, and under what circumstances. References Erford, B. T. (2011).

Diwali – Festival of Lights

Diwali  (also spelled  Devali  in certain regions) or  Deepavali,[1]  popularly known as the â€Å"festival of lights†, is an important five-day festival in  Hinduism,Jainism, and  Sikhism, occurring between mid-October and mid-November. For Hindus, Diwali is one of the most important festivals of the year and is celebrated in families by performing traditional activities together in their homes. Deepavali is an official holiday in  India,[2]  Nepal,  Sri Lanka,  Myanmar,Mauritius,  Guyana,  Trinidad & Tobago,  Suriname,  Malaysia,  Singapore,[3]  and  Fiji. The name â€Å"Diwali† is a contraction of â€Å"Deepavali† (Sanskrit:  Dipavali), which translates into â€Å"row of lamps†. [4]  Diwali involves the lighting of small clay lamps (diyas  or  dipas) in  Sanskrit:   ) filled with oil to signify the triumph of good over evil. During Diwali, all the celebrants wear new clothes and share sweets and snacks wit h family members and friends. Most Indian business communities begin the financial year on the first day of Diwali. Diwali commemorates the return of  Lord Rama, along with  Sita  and  Lakshman, from his fourteen-year-long exile and vanquishing the demon-king  Ravana.In joyous celebration of the return of their king, the people of  Ayodhya, the Capital of Rama, illuminated the kingdom with earthen  diyas  (oil lamps) and burst firecrackers. [5] In Jainism, Diwali marks the attainment of  moksha  or  nirvana  by  Mahavira  in 527 BC. [6][7]  In Sikhism,  Deepavali  commemorates the return of  Guru Har Gobind Ji  to  Amritsar  after freeing 52 Hindu kings imprisoned in Fort  Gwalior  by defeating Emperor  Jahangir; the people lit candles and diyas to celebrate his return. This is the reason Sikhs also refer to Deepavali as  Bandi Chhorh Divas, â€Å"the day of release of detainees†.The festival starts with  Dhanteras  on whi ch most Indian business communities begin their financial year. The second day of the festival,  Naraka Chaturdasi, marks the vanquishing of the demon  Naraka  by  Lord Krishna  and his wife  Satyabhama. Amavasya, the third day of Deepawali, marks the worship ofLakshmi, the goddess of wealth in her most benevolent mood, fulfilling the wishes of her devotees. Amavasya also tells the story of Lord  Vishnu, who in his dwarf incarnation vanquished the  Bali, and banished him to  Patala.It is on the fourth day of Deepawali,  Kartika Shudda Padyami, that Bali went to  patalaand took the reins of his new kingdom in there. The fifth day is referred to as  Yama Dvitiya  (also called  Bhai Dooj), and on this day sisters invite their brothers to their homes. ————————————————- Spiritual significance In each legend, myth and story of Deepawali lies the signi ficance of the victory of good over evil; and it is with each Deepawali and the lights that illuminate our homes and hearts, that this simple truth finds new reason and hope.From darkness into light — the light that empowers us to commit ourselves to good deeds, that which brings us closer to divinity. During Diwali, lights illuminate every corner of India and the scent of incense sticks hangs in the air, mingled with the sounds of fire-crackers, joy, togetherness and hope. Diwali is celebrated around the globe. Outside India, it is more than a Hindu festival, it's a celebration of South-Asian identities. 5] While Deepavali is popularly known as the â€Å"festival of lights†, the most significant spiritual meaning is â€Å"the awareness of the inner light†. Central to Hindu philosophy is the assertion that there is something beyond the physical body and mind which is pure, infinite, and eternal, called the  Atman. The celebration of Deepavali as the â€Å"vic tory of good over evil†, refers to the light of higher knowledge dispelling all ignorance, the ignorance that masks one's true nature, not as the body, but as the unchanging, infinite,  immanent  and  transcendent  reality.With this awakening comes compassion and the awareness of the oneness of all things (higher knowledge). This brings  ananda  (joy or peace). Just as we celebrate the birth of our physical being, Deepavali is the celebration of this Inner Light. While the story behind Deepavali and the manner of celebration varies from region to region (festive fireworks, worship, lights, sharing of sweets), the essence is the same – to rejoice in the Inner Light (Atman) or the underlying Reality of all things (Brahman).

Radium Facts and Chemical and Physical Properties

Radium Facts and Chemical and Physical Properties Atomic Number: 88 Symbol: Ra Atomic Weight: 226.0254 Electron Configuration: [Rn] 7s2 Word Origin: Latin radius: ray Element Classification: alkaline earth metal Discovery It was discovered by Pierre and Marie Curie in 1898 (France/Poland). It was isolated in 1911 by Mme. Curie and Debierne. Isotopes Sixteen isotopes of radium are known. The most common isotope is Ra-226, which has a half-life of 1620 years. Properties Radium is an alkaline earth metal. Radium has a melting point of 700Â °C, boiling point of 1140Â °C, specific gravity estimated to be 5, and valence of 2. Pure radium metal is bright white when freshly prepared, although it blackens upon exposure to air. The element decomposes in water. It is somewhat more volatile than the element barium. Radium and its salts exhibit luminescence and impart a carmine color to flame. Radium emits alpha, beta, and gamma rays. It produces neutrons when mixed with beryllium. A single gram of Ra-226 decays at the rate of 3.7x1010 disintegrations per second. [The curie (Ci) is defined to be the quantity of radioactivity which has the same rate of disintegration as 1 gram of Ra-226.] A gram of radium produces around 0.0001 ml (STP) of radon gas (emanation) per day and about 1000 calories per year. Radium loses about 1% of its activity over 25 years, with lead as its final disintegration product. Radium is a radiological hazard. Stored radium requires ven tilation to prevent the build-up of radon gas. Uses Radium has been used to produce neutron sources, luminous paints, and medical radioisotopes. Sources Radium was discovered in pitchblende or uraninite. Radium is found in all uranium minerals. There is approximately 1 gram of radium for each 7 tons of pitchblende. Radium was first isolated by electrolysis of a radium chloride solution, using a mercury cathode. The resulting amalgam yielded pure radium metal upon distillation in hydrogen. Radium is commercially obtained as its chloride or bromide and tends not to be purified as an element.

ocean water essays

ocean water essays 1. Introduction to open water waste disposal. 2. Introduction of oil into marine environments. 3. Introduction of plastics/pollutants into marine environments. 4. Possible solutions to waste disposal into our water systems. The oceans and the life they sustain have had enough. They can no longer endure the unwanted pollution of careless, inconsiderate people worldwide. The societies of this world need to wake up, and not only listen to, but understand that it is time to find better ways of dealing with wastes, rather than nonchalantly dumping it into our oceans. For decades people in societies worldwide have taken advantage of the Earth=s waters simply by dumping whatever they do not want into them. Apparently our time of easy disposal has run out, the oceans and the life within our showing distinct signs of poor health. The continuous dumping (or traditional dumping) of industrial wastes as well as sewage and garbage into the oceans is beginning to show definite signs of pollution caused stress. The National Research Council recently published information stating that human intervention has begun to take its toll on the marine environment. The ecological balance of oceans worldwide are at a dan gerously unstable state, the effects of man-made pollutants introduced into the waters and seas are having severe consequences upon the marine life living there. There is much that needs to be accomplished before scientists can fully understand how bad our oceans and seas really are. Even more importantly, is the fact that environmental action must be taken now to reduce the oceans growing plight. Arguably the most contributing polluters to our oceans are the major industries of the world. Industrial ocean pollution has incorporated a wide variety of polluters, ranging from major oil spills dispersing toxic chlorinated hydrocarbons (the resultant of the breakdown of petroleum) to PCB=s (polychlorinated biphenyls) as well as D...
