Such injuries are particularly common in sports that involve overhead throwing, like baseball, cricket, javelin and racket sports. Most UCL injuries are localized in the elbow joint. These injuries manifest as painful swellings and lead to elbow instability, rendering the sufferer incapable of playing any further. Thus, UCL injuries are also considered as the end of a sportsman’s career. Owing to modern science, many treatment modalities are now available for the treatment of UCL injuries, ranging from physical therapies to surgical interventions. Most minor injuries resolve on their own over time, often requiring only a minor period of rest. However, severe injuries demand surgical replacement of the ulnar collateral ligament. Recent advances in biomedical sciences have introduced novel modes of treatment that induce self-healing of the soft tissues in the patients. One such treatment is the use of Platelet rich plasma, derived from the patient’s own blood. PRP is rich platelets that release growth factors, which accelerate the

Propolis and Calcium Hydroxide Against Enterococcus Faecalis

Propolis and Calcium Hydroxide Against Enterococcus Faecalis Title: An in-vitro comparison of endodontic medicaments Propolis and Calcium hydroxide alone and in combination with Ciprofloxacin and Moxifloxacin against Enterococcus faecalis. Abstract: Aim: To evaluate and compare the antimicrobial properties of Propolis and Calcium hydroxide alone and in combination with Ciprofloxacin and Moxifloxacin against Enterococcus faecalis (E. Faecalis). Materials and Methods The laboratory study was carried out to test the effectiveness of propolis and calcium hydroxidealone as well as in combination with the established endodontic medicaments (Moxifloxacin and Ciprofloxacin). The various combinations were : Group1: Propolis, Group 2: calcium hydroxide, Group 3: Moxifloxacin, Group 4: Ciprofloxacin, Group 5: Propolis + Moxifloxacin, Group 6: Propolis + Ciprofloxacin, Group 7: Calcium hydroxide + Ciprofloxacin, Group 8: Calcium hydroxide + Moxifloxacin. The efficacy of these medicaments was tested by checking for the zone of inhibition for the specific strain (ATCC 29212) of Enterococcus faecalis at different time intervals i.e. 24hr, 48hr and 72hr. Results Mean zone of inhibition was maximum in Group V (21.94Â ±4.26) followed by Group VI (18.80Â ±1.93), Group I (18.71Â ±4.26), Group VIII (15.88Â ±2.59), Group III (14.91Â ±1.00), Group VII (14.57Â ±2.17), Group IV (13.91Â ±1.00) and minimum in Group II (12.89Â ±2.14). Mean zone of inhibition were found to be maximum at 72 hr and minimum at 24 hr. At all time intervals, the combination of Propalis with Moxiflocacin showed the maximum antimicrobial efficacy. Conclusion: On the basis of the results of the present study it can be concluded that Propolis and Calcium hydroxide show synergistic effect with Moxifloxacin and Ciprofloxacin against E. Faecalis. Propolis in combination with antibiotics and alone is more effective than calcium hydroxide. Clinical significance: Since propolis alone and in combination with antibiotics was observed to be more effective than calcium hydroxide, propolis can be considered as an intra canal medicament when compared to traditional calcium hydroxide. Key words: Calcium Hydroxide, Ciprofloxacin, E. fecalis, Intra canal medicaments, Laboratory research, Moxifloxacin, Propolis. Introduction: For successful endodontic treatment, proper diagnosis, thorough chemo-mechanical preparation, and three dimensional obturation of root canal space are paramount. Regardless of these treatment protocols, bacteria can still persist in the complex anatomy of root canal space, thus the ability of intra canal medicament to restrain or eliminate residual bacteria and prevent re-infection may play an increasingly important role in achieving and maintaining a higher success rate of root canal treatment.1 The most common species recovered in over one-third of the canals of root filled teeth with persisting periapical lesion is the Enterococcus faecalis (E. Faecalis). Enterococcus faecalis is a gram positive, facultative anaerobic, coccoid bacteria. Medicaments are recommended to eliminate remaining microbes in the root canal, dentinal tubules, accessory canals, canal irregularities (such as fins, transverse anastomoses, apical deltas and other ramifications) and in the periapical/periodontal tissue to reduce periapical inflammation, encourage periapical healing, eliminate apical exudates, control inflammatory root resorption and avert contamination of the canal between appointment.2 Earlier strong intracanal antiseptics such as formacresol and camphorated parachlorophenol were used, but due to their detrimental effects on the connective tissue, their use is limited, now-a-days. The excellent biologic and antimicrobial properties of calcium hydroxide have made it the preferred choice for intracanal dressing of the infected roots canals.1 Calcium hydroxide has been added to several endodontic sealers to improve their biological properties and to augment their antibacterial activity. When used as an intracanal medicament, the most important property of calcium hydroxide is its strong antimicrobial activity. Its high pH alters the biological lipopolysaccharides in the cell walls of Gram-negative species, there by inactivating the membrane transport mechanisms.3 Propolis is a resinous product rich in flavanoid. It has been used as in a number of ways; an anticaries agent, for dentinal hypersensitivity as sealant, storage medium for avulsed tooth, for pulp capping. Propolis is ten times less cytotoxic than calcium hydroxide and has a distinguished antibacterial, antifungal, antiviral, immunomodulatry, antioxidant effect. Recent studies have reported that propolis is more effective against resistant microorganisms and is biocompatible. In endodontic procedures antibiotics can be used as an important aide but their ineffectiveness through systemic route of administration has led to the intra canal application, in order to increase their efficacy.1 Moxifloxacin and Ciprofloxacin are members of the quinolones. Among the drugs commonly used for endodontic infection, ciprofloxacin is indicated due to its efficient action against oral anaerobes, gram +ve aerobic microorganisms (Staphylococcus aureus, S. epidermidis, Sptreptococcus spp) and gram -ve enterobacteria (Escherichia coli, Enterobacter spp and Pseudomonas), which show MIC90 between 0.015 and 2 ÃŽ ¼g/mL respectively. All the species of streptococcus are sensitive to concentrations between 1.0 and 8.0 ÃŽ ¼g/mL; Other Streptococcal species like S. aureus and S. epidermidis are also sensitive to concentrations between 0.25 and 1.0 ÃŽ ¼g/mL.4,5 Ciprofloxacin has antimicrobial activity against most Gram-negative bacilli and cocci but limited activity against most Gram-positive organisms. Moxifloxacin is a new fluoroquinolone with expended spectrum of activity, including anaerobes and Gram positive organisms, especially the multi-resistant ones.3,6-10 Moxifloxacin has been found to be one of the most active antibiotics against E. faecalis with the lowest MIC50 and MIC90. From the previous literature it has been proved that ciprofloxacin to be more active other antibiotics.3,6,8,9,11 The usage of local antibiotics in endodontic treatment was advocated by Grossman in 1951. Since then numerous antibiotics have been used during endodontic treatment. The antibiotic combination has proved advantageous with the usage of triantibiotic paste.12 The laboratory study was carried out to test the effectiveness of propolis and calcium hydroxidealone as well as in combination with the established endodontic medicaments (Moxifloxacin and Ciprofloxacin). Materials and method: The study was carried out in the Department of Conservative Dentistry and Endodontics and Department of Microbiology at Saraswati Dental College and Hospital, Lucknow, India. Propolis (Hi-Tech Natural product India Ltd), Calcium Hydroxide (Vishaldentocare), Moxifloxacin (Avelox), Ciprofloxacin (Ciplox-500) were used in this study. They were distributed in different groups as presented in table no 1. The efficacy of these medicaments was tested by checking for the zone of inhibition for the specific strain (ATCC 29212) of Enterococcus faecalis at different time intervals i.e. 24hr, 48hr and 72hr. Specific stain (ATCC 29212) of Enterococcus Faecalis was procured and grown on Brain Heart Infusion Broth (BHI) under favorable temperature overnight and the growth was checked by changes in the turbidity at 24 hours. Blood Agar Media Plate was inoculated with Enterococcus faecalis (ATCC 29212) by spreading the culture over the surface of the plate with a swab. Intermittent scraping of the culture was done at different sites to make wells for the placement of experimental intracanal medicament. The experimental groups were used in their minimum inhibitory concentration (MIC) against Enterocaccus faecalis (ATCC 29212). MIC of the various antibiotics used in this study was – Propalis 340 Â µg/mL, Calcium hydroxide 2500 Â µg/mL, Moxifloxacin 2 Â µg/mL and Ciprofloxacin 8 Â µg/mL .2,13 Propolis, Calcium hydroxide and antibiotics were used as a paste in which saline acted as a vehicle. Propolis and Calcium hydroxide were mixed separately with saline on a glass slab, with the help of cement spatula, to prepare the paste. For obtaining the antibiotic paste, tablets of Ciprofloxacin and Moxifloxacin were crushed in mortar and pestle and then mixed with saline on glass slab with cement spatula. Plates were subjected to incubation at 30 Â °c for 24hrs, 48 hrs and 72 hrs (Figure 1) and the diameter of the zones of inhibition were measured in millimeters with HiAntimicrobial Inhibition Zone Scale tm C (HiMedia Laboratories Pvt Limited, Mumbai) (Figure 2). The observations were subjected to descriptive and inferential (ANOVA) statistical analysis. Results: Table 2 shows the mean zones of inhibition in different groups irrespective of time. Zones of inhibitions ranged from 10 mm (Group II) to 28 mm (Group VI). Mean zone of inhibition was maximum in Group V (21.94Â ±4.26) followed by Group VI (18.80Â ±1.93), Group I (18.71Â ±4.26),Group VIII (15.88Â ±2.59), Group III (14.91Â ±1.00), Group VII (14.57Â ±2.17), Group IV (13.91Â ±1.00) and minimum in Group II (12.89Â ±2.14). Table 3 shows the ANOVA applied in different groups. Statistically, intergroup differences were significant (p Group I ~ Group VI > Group VIII ~ Group III ~ Group VII ~ Group IV ~ Group II. Table 4 shows the mean zones of inhibition at different time intervals in different groups. Mean zone of inhibition were maximum at 72 hr and minimum at 24 hr, and the intergroup differences were significant. At all the time intervals, group V showed the maximum antimicrobial efficacy. Discussion: Intracanal medicaments are used to eliminate remnant microbial flora after a thorough chemo-mechanical preparation of root canal and hasten the healing process. Propolis which is a very effective natural product and has been a part of popular medicine since thousands of years 14, 15. The color of Propolis is dark. Made from material collected from plants by bees, It is used against pathogenic microorganisms. Due to its anti-inflammatory properties it is effective against infection, rheumatism, muscular and articular diseases, and other types of inflammation.15-17 The chemical composition of propolis varies widely. Over 200 substances have been identified in the various varieties of propolis extracted from various geographical regions, which includes phenolic acids, esters, flavonoids, alcohols, aromatic aldehydes, fatty acids, amino acids, vitamins and minerals. Special emphasis is given to the flavonoids and phenolic acids mainly responsible for its biological activity. Propolis exh ibits antimicrobial and anti-inflammatory properties, that why it has been suggested as a root canal medicament.15,18,19 Calcium hydroxide, a white, odorless powder is one of the main stay of the root canal medicaments. It has a low solubility in water, insoluble in alcohol and a high pH. The extended clinical action of calcium hydroxide is well known. It is biocompatible, and has antimicrobial and anti-inflammatory action; it also activates the alkaline phosphatase enzyme, which in turn induces mineralized tissue formation and aid in the repair process. Chemically it is classified as a strong base, and when it is associated with a suitable vehicle produces an alkaline paste. Calcium hydroxide paste dissociates into calcium and the hydroxyl ions, the resulting environment will turn alkaline because of hydroxyl ions, due to this action it is a very good root canal dressing material. For the destruction of pathogenic bacteria of root canal and dentinal tubules , these hydroxyl ions should be capable to diffuse in dentin and persist in pulp tissues in a maximum concentration to produce the pH level requir ed 15,20. Moreover various other studies reported by Molander A. and Tirali et al found CaOH to have synergistic effect with other endodontic medicaments.21,22 Ciprofloxacin, a second generation fluoroquinolone antibiotic, inhibits bacterial DNA synthesis. In dentistry, it is used as a broad spectrum antimicrobial and is effective against gram negative bacteria (staphylococcus and pseudomonas). One of the important drugs of fourth-generation syntheticfluoroquinolone is Moxifloxacin. It has superior activity against Gram+ve bacteria and anaerobes as compared to levofloxacin and ciprofloxacin.Moxifloxacin is abroad-spectrum antibioticthat is active against bothGram-positiveandGram-negativebacteria. It inhibitsDNA gyrase, enzyme which inhibit cell replication by separating bacterial DNA 12. First and second generation fluoroquinolones selectively inhibit topoisomerase II ligase domain, which leaves the two nuclease domains intact. This particular modification, coupled with the stable action of the topoisomerase II within the cell of bacteria through nucleasic activity of the intact enzyme leads to DNA fragmentation. The further generations of fluoroquinolones i.e third and fourth acts selectively for topoisomerase IV ligase domain, which makes them more effective against gram positive coverage.12,23 Antimicrobial property of propolis is due to inhibition of bacterial DNA-dependant RNA polymerases. Synergism amid antibacterial agents and propolis has been observed by Madarova L in 1980. Grange JM and Davey RW found that there was synergism between antimicrobial drugs and propolis against S. aureus particularly those which interfere with bacterial protein synthesis.24-26 Noori Al-Wahi found propalis to have synergistic properties with honey.27 Although calcium hydroxide does not bond to dentin, it does have antibacterial property. Its mechanism of actions is through the ionic break down of Ca(+) and OH(-) ions and corresponding effects on vital tissues. Protein denaturation and damage to DNA and cytoplasmic membranes are responsible for fatality of calcium hydroxide on bacterial cells .28 E fecalis appears to be highly resistant to the antimicrobial effect of calcium hydroxide. Evans et al. reported that at pH of 11.1, E. faecalis was resistant to calcium hydroxide but unable to survive at higher pH. After intracanal dressing of calcium hydroxide in radicular dentin, due to its buffering effect, the alkalinity may only reach a ph of 10.3. This one factor may be responsible to the resistance of E faecalis to Calcium hydroxide. The presence of proton pump in the cell wall of E faecalis, could be another reason for its resistance towards Calcium hydroxide.29 In the present study Propolis alone and with antibiotic was found to be more effective than calcium hydroxide and calcium hydroxide with antibiotics. Rezende Ceps R et al and Jahromi MZ et al have also found propolis to be more effective than CaOH. Propolis showed the synergistic effect with ciprofloxacin and moxifloxacin at all time intervals.13,30 In this study Propolis showed maximum efficiency against Enterococcus faecalis in combination with Moxifloxacin followed by Ciprofloxacin, which is similar to the results obtained by Krolet et al, Fernandis A et al, Ricardo Oliveria et al, Gheda Helaly et al, Kracko M et al and Stepanovic S et al who found propolis to have synergistic effect with various antibiotics.31-36 Calcium hydroxide also showed synergistic effect with antibiotic at all time intervals, which was maximum with Moxifloxacin followed by Ciprofloxacin at all time intervals. Conclusion: On the basis of the results of the present study it can be concluded that Propolis and Calcium hydroxide show synergistic effect with Moxifloxacin and Ciprofloxacin against E. Faecalis. Propolis in combination with antibiotics and alone is more effective than calcium hydroxide. The use of Moxifloxacin as an intracanal medicament should be seriously explored. In order to draw more definitive conclusions, a wider and more detailed study needs to be undertaken. Clinical significance: Since propolis alone and in combination with antibiotics was observed to be more effective than calcium hydroxide, propolis can be considered as an intracanal medicament when compared to traditional calcium hydroxide.

A Midsummer Nights Dream by William Shakespeare :: A Midsummer Nights Dream, William Shakespeare

William Shakespeare's A Midsummer Night's Dream is very unique because there is a play within a play. Shakespeare uses the interesting qualities of the characters to narrate the play. The characters can be divided into four groups: The Athenian Court (The Duke, Hippolyta, Egeus, and Philostrate); the young lovers (Hermia, Lysander, Helena, and Demetrius); the fairy kingdom (Oberon, Titania, Puck, and the lesser fairies); and the workmen (Bottom, Quince, Flute, Snout, Starveling, and Snug). The Athenian court is the obvious upper class division of scoiety in Athens. Theseus is head of the Athenian state and his role is to maintain justice. Hippolyta is Theseus's new bride and shows sympathy to the young lovers. Both Theseus and Hippolyta are classified as legendary characters and collectively show their maturity and commitment to marriage. Egeus is a stubborn father whose character loses worth toward the end of the plot, while Philostrate's part is short and undeveloped. Despite being a group, the young lovers are more interesting than the Athenian court. 2 The male young lovers are somewhat similar in qualities. They are young and fall in and out of love quickly. For example Demetrius and Lysander both reject a girl they once loved; they fight over a one girl and then over the other. On the other hand, Hermia and Helena are not as similar because Hermia is short and Helena is tall. These characters are more interesting than the Athenian court because they provide the theme of commitment and being unfaithful. The young lovers are touched by magic by the fairy kingdom members. A member of the fairy kingdom, Oberon is resentful and generous at that the same time. Case in point, Oberon is resentful toward Titania refuses to hand over her boy, and generous in his attempt to make things go well for the the young lovers. Titania is a strong individual and stands up for herself against Oberon. But Titania too also is generous showing love for Bottom. Lastly, Puck is as servant for Oberon and does exactly what he says. Unfortunately he does not do everything correctly. For instance, Oberon requests that Puck use magic on Demetrius to return Helena's love, however he employs the magic upon Lysander instead. Puck means well but isn't necessarily given the respect due to him.

It was the largest such filing in U.S. history. 2003: The Company’s total assets had been inflated by about $11 billion. Creditors had lost faith in the organization. 2004: MCI officially emerges from bankruptcy, 21 months after filing the largest Chapter 11 case in history. 2005: Verizon Communications Inc. announces a $6.75 billion deal to buy MCI Inc. Former WorldCom Inc. chief executive Bernard J. Ebbers is found guilty of conspiracy, securities fraud and making false filings with regulators. Worldcom Top Management Team during Scandal: CEO – Bernard Ebbers CFO – Scott Sullivan Comptroller – David Myers Director of General Accounting – Buford â€Å"Buddy† Yates Pre-Scam Days At WorldCom LDDS changed its name to WorldCom in 1995. WorldCom was the second largest benchmarked long distance telecom provider in the USA and the biggest internet traffic carrier in the world, with a network stretching over 150,000km, and business presence in more than 65 countries. WorldCom faced explosive growth, at a scorching pace over the 15 years of its existence by acquiring many companies like MFS Communications Inc. and UUNet Technologies Inc. in 1996, MCI Communication Corp, Brooks Fiber Properties Inc., CompuServe Comp in 1998. In 2001, it made the largest merger with Intermedia Communication Inc., an internet and data services provider. With the acquisitions of UUNet and MCi, WorldCom had control over more than 50% of the Internet backbone infrastructure. Every acquisition led to higher stock price which in turn made way to finance another acquisition. The share price of WorldCom was at an all time high of $63.50, on June 18, 1999, with market value of $125 billion. Its value rose to $180 billion during the peak of the telecom boom. As long as the stock market was booming and the dot com bubble was expanding, no one cared to look into the fundamental stability of the company. Auditors also failed to perform thorough due diligence. WorldCom, in the late 1990’s was also an attractive takeover target for Nextel Communications, before the scandal. Scam – How it all happened? WorldCom, the second biggest long-distance telecom company in US and also the biggest carrier of Internet traffic in the world was the new economy company when it was launched. In its operation of 15 years, the company grew at a very rapid pace, majorly due to the ambition of its former chief executive officer (CEO) Bernard J. Ebbers. It majorly expanded by acquiring other smaller companies who had a potential to be their future competitors. The stock market supported them and the company growth was exorbitant and no one cared about the fundamentals of the company as it was giving high return year on year. Below mentioned is the chronological order of occurrence of events and the exposure of fraud. * March 2002 – The U.S. Securities and Exchange Commission (SEC) questioned WorldCom about its accounting procedures and about loans it had extended to its officers as it was curious about the rationale behind the offers. * April 2002 – The first sign of weakness came when company announced job cuts, the number was 3,700. Following the even, Standard & Poor’s, Moody’s and Fitch downgraded WorldCom’s credit rating and it was the beginning of the Justice department launching a probe into the scandal. * April 2002 – This month itself J. Ebbers resigned as CEO after the shocking revelation of lending of $339.7 million to Ebbers to cover loans that he took to buy his own shares. * June 25 – The Company revealed that improper accounting of $3.8 billion in expenses had covered up a net loss for 2001 and the first quarter of 2002. The company also announced that it planned to shed more than 20% of its workforce counting to be around 17,000 jobs. * June 26 – The case was filed by SEC against WorldCom alleging them for a securities fraud. It alleged that WorldCom’s top management â€Å"disguised its true operating performance† and â€Å"misled inve stors about its reported earnings†. Method that WorldCom adopted is been classified as an accounting scandal, the company used its balance sheet to boost revenues and profits while hiding expenditures. It did so by * Classifying ordinary day-to-day expenses and long-term expenses associated with the acquisition of capital assets as investments which led to WorldCom having a significant tax advantages. * WorldCom also tried to hide expenses to the amount of nearly $4 billion and instead showed them as profits in their account books. * Another ploy it employed was using WorldCom’s major operating expenses related to its â€Å"line costs†, the fees that it pays to third party telecom network providers for the right to access their networks. WorldCom capitalised these fees, terming them as investments, when, in fact, they were one of the most important day-to-day expenses. Financial experts pointed out that WorldCom’s accounting practices, made it impossible for investors to gauge the performance of the company. They not only overstated profitability they also misled the investors by the opaque nature of its regular operating performance. The shock for the people accentuated with revelation of Arthur Andersen, the disgraced auditing and consulting major as WorldCom’s auditor too. The WorldCom’s own internal audit department was the first one who unearthed the fraud of approximately $3.8 billion in June 2002. The company’s audit committee and board of directors were notified of the fraud and acted swiftly: Sullivan was fired, Myers resigned. By the end of 2003, it was estimated that the company’s total assets had been inflated by around $11 billion (WorldCom, 2005). Post-Scam Days At WorldCom Around 17,000 jobs were cut in order to save $1 billion. The company had yet to pay many of its creditors. Many of the small creditors included former employees, primarily those who were dismissed during June 2002. On August 7, 2002, the exWorldCom 5100 group was formed. It included former WorldCom employees with a common goal of seeking the benefits and full payment of severance pay under the WorldCom Severance Plan. The â€Å"5100† signifies the number of WorldCom employees dismissed in June 2002 before WorldCom filed for bankruptcy. In 2004, the company emerged from bankruptcy, with $5.7 billion in debt and $6 billion in cash. It was renamed MCI. About half of the cash was intended to pay various claims and settlements. Previous bondholders were paid 35.7 cents on the dollar, in bonds and stock in the new MCI company. The previous stockholders’ stock was cancelled, causing huge loss to stockholders. On February 14, 2005, Verizon Communications acquired MCI for $7.6 billion. On March 15, 2005 the CEO , Bernard Ebbers, was found guilty of all charges and convicted of fraud. He was accounted for the $11 billion accounting scandal, conspiracy and filing false documents with regulator. Many other officials were also charged with criminal penalties in relation to the company’s financial misstatements. These included former CFO Scott Sullivan (entered a guilty plea on March 2, 2004 to one count each of securities fraud, conspiracy to commit securities fraud, and filing false statements), former comptroller David Myers (pleaded guilty to securities fraud, conspiracy to commit securities fraud, and filing false statements on September 27, 2002), former accounting director Buford Yates (pleaded guilty to conspiracy and fraud charges on October 7, 2002), and former accounting managers Betty Vinson and Troy Normand (both pleading guilty to conspiracy and securities fraud on October 10, 2002). On July 13, 2005 Bernard Ebbers received a sentence of imprisonment for 25 years. At that time, Ebbers was 63 years old. On September 26, 2006, Ebbers surrendered himself to the Federal Bureau of Prisons prison at Oakdale, Louisiana, the Oakdale Federal Corrections Institution to begin serving his sentence. During March 2005, 16 of WorldCom’s 17 former underwriters reached settlements with the investors. During December 2005, MCI joined Microsoft Corporation by providing Windows Live Messenger customers â€Å"Voice Over Internet Protocol† (VoIP) service to make telephone calls. This was MCI’s last new product—- called â€Å"MCI Web Calling†. This product was renamed â€Å"Verizon Web Calling†, after the merger. Corporate governance Failure In 2002, when world’s second largest telecom giant WorldCom filed for bankruptcy at federal court in Manhattan, United States witnessed one of the largest accounting frauds in history. Former CEO of WorldCom, Mr. Bernie Ebbers was held responsible for orchestrating the USD 11 billion accounting fraud and sentenced to 25 years in federal prison on July 13, 2005. WorldCom fiasco is a clear case of corporate governance failure. How could a fraud of such enormity go unnoticed by the Board of Directors at WorldCom? What happened to industry watchdogs? In WorldCom’s case, most of the deviations from proper corporate behaviour resulted from the failure of Board of Directors to recognize and effectively deal with the aftermaths of â€Å"greed culture†. WorldCom’s former CEO Bernie Ebbers’ desire to build and protect his personal wealth was the driving factor behind the fraud. For this reason, he had to show continually growing net worth in order to avoid margin calls on his own WorldCom stock that he had pledged to secure loans [1]. While probing this enormous failure in corporate governance and what could have been done to evade it, we came across an interesting document entitled â€Å"Report of Investigation† dated March 31, 2003. This Report was prepared for, among others, the Federal Bankruptcy Court overseeing WorldCom case [1]. From the report, we have drawn various points to understand the corporate governance failure at WorldCom. Accounting Misstatements WorldCom made major accounting misstatements that hid the increasingly perilous financial condition of the company. The Report described the accounting tomfoolery as follows: â€Å"†¦ As enormous as the fraud was, it was accomplished in a relatively mundane way: more than $9 billion in false or unsupported accounting entries were made in WorldCom’s financial systems in order to achieve desired reported financial results.† Drivers of the fraud The motivating factor behind this fraud was the business strategy (personal) of WorldCom’s CEO, Bernie Ebbers. Here was a man who put his personal gain above organization’s growth. In the 1990s, Ebbers wanted to achieve spectacular growth through a series of acquisitions. But, there was a catch – He did NOT have the necessary resources to fund his acquisition binge. So, he used WorldCom stocks to accomplish his shopping (acquisition) spree. But, the most important thing was, WorldCom stock had to continually increase in value to be of any use to Ebbers personal agenda. He felt the need to prove ever-growing revenue and income. His only option to accomplish this end was financial gimmickry. However, he faced the age-old problem which all conmen face – It is difficult to sustain deception in the long run! Complicating Ebbers’ circumstances was an industry-wide slump in telecommunications. During this time, Wall Street had continuing expectations of double-digit growth for WorldCom. After all, they had accomplished so much in such a relatively short period of time. But, WorldCom needed time to learn managing the new businesses it had acquired. To continue on the path of double digit growth, WorldCom had to consolidate the acquired businesses and turn them into money minting machines. However, Ebbers did not have the backbone to stand up and accept that WorldCom needed time. Instead he went ahead and presented Wall Street what it expected from WorldCom – Ever-growing revenues and income even when in reality none existed. He fudged the company books and met Wall Street’s expectations. Another major reason motivating this fraud was Ebbers’ very obvious aspiration to build and guard his personal financial situation. For this reason, he had to show continually growing net worth in order to avoid margin calls on his own WorldCom stock that he had pledged to secure loans [1]. He did that. While most of the reports blame Ebbers for the entire episode, the Board of Directors are not blameless. WorldCom supported revisionist model of Corporate Governance – though the Board reigns (de jure), the imperial CEO rules (de facto). WorldCom’s corporate governance failure resulted in the following: * Company filed for bankruptcy * CEO was sentenced to 25 years of imprisonment * Shareholders saw their shares become useless * Lenders were strained to take losses on their loans * Employees lost jobs Court Ordered Fix The Bankruptcy Court directed the newly constituted Board of Directors and the newly appointed Corporate Monitor to fix this horrible example of corporate failure. The measures suggested.., * A corporate culture of openness, in which ethical conduct is encouraged and expected, as exemplified by the ethics pledge that the Company and the Corporate Monitor have developed and that senior management has signed * A corporate culture in which the counsel of lawyers is sought and valued; * Formalized and well-documented policies and procedures, including a clear and effective channel through which employees can raise concerns or report acts of misconduct References: 1. http://www.referenceforbusiness.com/history2/10/MCI-WorldCom-Inc.html#ixzz2IriwULfD 2. http://en.wikipedia.org/wiki/MCI_Inc. 3. http://www.fundinguniverse.com/company-histories/mci-worldcom-inc-history/ 4. http://www.washingtonpost.com/wp-dyn/articles/A49156-2002Jun26.html 5. http://www.ecommercetimes.com/story/45542.html 6. http://www.sec.gov/Archives/edgar/data/723527/000093176303001862/dex991.htm 7. http://www.frontlineonnet.com/fl1915/19150810.htm 8. http://www.guardian.co.uk/business/2002/aug/09/corporatefraud.worldcom2 9. http://www.nytimes.com/2002/07/22/us/worldcom-s-collapse-the-overview-worldcom-files-for-bankruptcy-largest-us-case.html 10. http://voices.yahoo.com/worldcom-scandal-look-back-one-biggest-225686.html?cat=3 11. http://www.nytimes.com/2002/07/22/us/worldcom-s-collapse-the-overview-worldcom-files-for-bankruptcy-largest-us-case.html 12. http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=3&cad=rja&ved=0CDkQFjAC&url=http%3A%2F%2Fmoney.cnn.com%2F2005%2F03%2F15%2Fnews%2Fnewsmakers%2Febbers%2F&ei=yOkAUZbcKcbirAeVwIC4BA&usg=AFQjCNHSfWmXHV-ryl3POQ1NU_MMYLmvjA&bvm=bv.41524429,d.bmk 13. http://www.nytimes.com/2002/07/22/us/worldcom-s-collapse-the-overview-worldcom-files-for-bankruptcy-largest-us-case.html 14. http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=3&cad=rja&ved=0CDkQFjAC&url=http%3A%2F%2Fmoney.cnn.com%2F2005%2F03%2F15%2Fnews%2Fnewsmakers%2Febbers%2F&ei=yOkAUZbcKcbirAeVwIC4 BA&usg=AFQjCNHSfWmXHV-ryl3POQ1NU_MMYLmvjA&bvm=bv.41524429,d.bmk

Conserve and Preserve Essay

With today’s growing population, resource consumption is becoming a huge concern. It is important that humans realize what is best for both our present and future generation, and what is best for our planet. We must preserve certain areas from being destroyed to keep their natural beauty. We should also conserve resources, so they can continue to flourish, but also so we can continue to live our lives without depleting these resources. Every individual unit of the environment works together to maintain a balance that supports the cycle of life. Humans must co-exist in a positive way with these units. We should live in a way that does not exploit any part of nature. We should not only respect and sustain the environment for our own benefit and for future generations, but also because nature itself is good on its own. When looking at preservation and conservation, there is not one that is better the other. Like many other rules and sets of standards, there are exceptions. Preservation is the action of protecting a certain thing or area completely. Conservation is a form of preservation, where we can use a particular resource or portion of land, in this case, but it is used sparingly and sustainably. There are certain situations where preserving something is beneficial. Then there are other situations where conserving something would be better for a larger number of living things. It would be ideal to say that we should strive to preserve nature in all scenarios but that is not a practical approach because there are certain needs that we as human beings have to fulfill that we can only get from nature. Certain medicines that keep people alive can be found in nature. If for instance a plant has the ability to save someone’s life, then it would be acceptable to cut that plant down to help heal the patient. There are some exceptions to this of course. It would be wrong to cut down the plant if it was unable to be replaced. The plant should be plentiful and able to thrive as a species before we use it to help our own species. For the most part, humans are put on a higher scale than some other species. This is not to say that we should disregard those species or over-use them, but if it came down to a life or death situation for a person, using the plant would be ethical. There are other scenarios in which preservation would be a better approach. An example of this is mountaintop removal. It does not seem ethical to be destroying such a beautiful object that forms naturally just so that we can have access to coal seams. The coal extracted from the mountain is only beneficial for a certain amount of time but the negative consequences from the whole process will be felt a lot longer (Copeland). Even though the mountain itself since it is not a living, breathing organism, it is important to respect the natural beauty of the mountain. The animals and plants that may reside on the mountain are also affected by this, and that should be taken into consideration. Another example of a time when it is best to preserve is in the case of an endangered organism. Say for instance that a certain tree is being cut down at an alarming rate to make paper. The tree will cease to exist if we continue at the rate that we are going. Then we should stop all chopping down of that particular tree. We should preserve it and allow it to continue to live, not just so that in the future we still have that tree around to produce more paper, but because it is a living thing that has value on its own. Our population is growing, and we have to figure out the best way to use our resources. Garrett Hardin also recognizes this as a problem in his essay â€Å"Lifeboat Ethics†, but takes the stance that if we help the poor people; we are hurting them in the long run. He believes that the biggest factor for overpopulation is the fact that poor countries multiply and increase their population at a much faster rate than countries that are predominately rich. Because of this, the problems associated with too many people in one area will continue to grow larger. This is because rich countries have the resources to support their people more so than the poorer countries that cannot even begin to help their people (Hardin). Getting food is a major concern of many people who think that overpopulation is becoming a problem. Hardin also recognizes this as a problem, but takes the stance that if we help the poor people; we are hurting them in the long run. Conservation becomes important when taking the population into consideration. Overpopulation will have a large impact on the environment because there will obviously be more of a need for basic elements such as water, food, and shelter. With more people demanding food, more livestock will need to be bred; more fruits and vegetables will need to be grown. With more people demanding shelter, more land will need to be plowed in order to build houses. With more people on the earth demanding water, more freshwater sources will be dried up. Not only are the necessities factored into the problem but with more people, all the luxuries and small things will add up also. There will be a higher demand of medicines, paper, and other goods that we can get from nature. The increase of human life will create a huge blow for the environment. It is important that we prevent our world from becoming a commons open to everyone, where people use their resources foolishly and greedily. Since people are part of the whole equation that makes up the environment, we should care and respect others. However, in feeding the poor, they do not realize their problems and continue to reproduce, thus putting them and the country in a deeper hole. This too has an effect on the environment because in the search for food, people do things that do not support a sustainable cycle. An example of this is the fact that since there are more people and getting meat to them is a long process, factory farms have taken the place of actual farms. Animals are now bred to grow faster and jacked up with hormones in an attempt to get them to the slaughterhouse faster so that the demands of consumers can be met. Also in order to keep up with more people, that means that there must be more animals to begin with. Livestock are crowded into small cages where they are unable to turn around, they are not able to live with their young, they pick up diseases and many other problems arise from this. This affects the life of the livestock obviously, but also affects the life of the consumer who then eats the meat. It is understandable that individuals want to eat meat because they say it tastes good, it is high in protein, and it’s convenient as well. However, the way that humans do it is immoral and wrong. We do not give the animals any chance of survival or even a chance at life to begin with. It would be more justifiable for people to go out and hunt their meat like people used to do. Then the animals would be able to live a normal life up until they were killed. This would also cut down on the air pollution that comes from factory farms, reduce the amount of water that is needed to produce meat, reduce the amount of crop space that is needed to feed the livestock, and reduce the amount of drugs that the consumer also eats after the animals are fed them. This brings the argument back around to the fact that the population is growing and that there are starving people all around the world. If reduced their consumption meat, then there would not be as big of a need for livestock. Thus the crops that are grown to feed the cows could be fed to the people who need it. We could also stop cutting down trees and destroying forests that is normally needed in order to make room for all that food that needs to be produced. Around the world 756 million tons of grain is fed to livestock and almost half of the 225 million tons of soy that is produced yearly also goes to feed the animals that we eat (USDA). These crops could be used to feed people in starving countries. It could affect the lives of people right here in America. Our population is growing very quickly and resources are becoming scarcer every day. We should want to preserve and conserve the natural world around us. Whether a person believes that another living thing has rights or not, they should still treat it with respect and care. One person or a small group of people should not make the ultimate decisions on what is considered worthy of life or unworthy. If people took the time to consider the feelings and consideration of the living things in nature, the world would be a better place not just for us now, but for future generations.

Early Inventors and Innovators of Electricity

Early Inventors and Innovators of Electricity The history of electricity begins with William Gilbert, a physician who served Queen Elizabeth the first of England. Before William Gilbert, all that was known about electricity and magnetism was that the lodestone possessed magnetic properties and that rubbing amber and jet would attract bits of stuff to start sticking. In 1600, William Gilbert published his treatise De magnete, Magneticisique Corporibus (On the Magnet). Printed in scholarly Latin, the book explained years of Gilberts research and experiments on electricity and magnetism. Gilbert raised the interest in the new science greatly. It was Gilbert who coined the expression electrica in his famous book. Early Inventors Inspired and educated by William Gilbert, several Europeans inventors, including Otto von Guericke of Germany, Charles Francois Du Fay of France, and Stephen Gray of England expanded the knowledge. Otto von Guericke was the first to prove that a vacuum could exist. Creating a vacuum was essential for all kinds of further research into electronics. In 1660, von Guericke invented the machine that produced static electricity; this was the first electric generator. In 1729, Stephen Gray discovered the principle of the conduction of electricity. In 1733, Charles Francois du Fay discovered that electricity comes in two forms which he called resinous (-) and vitreous (), now called negative and positive. The Leyden Jar The Leyden jar was the original capacitor, a device that stores and releases an electrical charge. (At that time electricity was considered the mysterious fluid or force.) The Leyden jar was invented in Holland in 1745 and in Germany almost simultaneously. Both Dutch physicist Pieter van Musschenbroek and German clergyman and scientist, Ewald Christian Von Kleist invented a Leyden jar. When Von Kleist first touched his Leyden jar he received a powerful shock that knocked him to the floor. The Leyden jar was named after Musschenbroeks hometown and university Leyden, by Abbe Nolett, a French scientist, who first coined the term Leyden jar. The jar was once called the Kleistian jar after Von Kleist, but this name did not stick. History of Electricity - Ben Franklin Ben Franklins important discovery was that electricity and lightning were one and the same. Ben Franklins lightning rod was the first practical application of electricity. History of Electricity - Henry Cavendish and Luigi Galvani Henry Cavendish of England, Coulomb of France, and Luigi Galvani of Italy made scientific contributions towards finding practical uses for electricity. In 1747, Henry Cavendish started measuring the conductivity (the ability to carry an electrical current) of different materials and published his results. In 1786, Italian physician Luigi Galvani demonstrated what we now understand to be the electrical basis of nerve impulses. Galvani made frog muscles twitch by jolting them with a spark from an electrostatic machine. Following the work of Cavendish and Galvani came a group of important scientists and inventors, including Alessandro Volta of Italy, Hans Oersted of Denmark, Andre Ampere of France, Georg Ohm of Germany, Michael Faraday of England, and Joseph Henry of America. Work With Magnets Joseph Henry was a researcher in the field of electricity whose work inspired many inventors. Joseph Henrys first discovery was that the power of a magnet could be immensely strengthened by winding it with insulated wire. He was the first person to make a magnet that could lift 3,500 pounds of weight. Joseph Henry showed the difference between quantity magnets composed of short lengths of wire connected in parallel and excited by a few large cells, and intensity magnets wound with a single long wire and excited by a battery composed of cells in series. This was an original discovery, greatly increasing both the immediate usefulness of the magnet and its possibilities for future experiments. Michael Faraday,  William Sturgeon, and other inventors were quick to recognize the value of Joseph Henrys discoveries. Sturgeon magnanimously said, Professor Joseph Henry has been enabled to produce a magnetic force which totally eclipses every other in the whole annals of  magnetism, and  no parallel is to be found since the miraculous suspension of the celebrated Oriental impostor in his iron coffin. Joseph Henry also discovered the phenomena of  self-induction  and mutual induction. In his experiment, a current sent through a wire in the second story of the building induced currents through a similar wire in the cellar two floors below. Telegraph A telegraph was an early invention that communicated messages at a distance over a wire using electricity that was later replaced by the telephone. The word telegraphy comes from the Greek words  tele  which means far away and  grapho  which means write. The first attempts to send signals by electricity (telegraph) had been made many times before  Joseph Henry  became interested in the problem.  William Sturgeons  invention of the electromagnet encouraged researchers in England to experiment with the electromagnet. The experiments failed and only produced a current  that weakened after a few hundred feet. The Basis for the Electric Telegraph However, Joseph Henry strung a mile of fine wire, placed an intensity  battery  at one end, and made the armature strike a bell at the other. Joseph Henry discovered the essential mechanics behind the electric telegraph. This discovery was made in 1831, a full year before  Samuel Morse  invented the telegraph. There is no controversy as to who invented the first telegraph machine. That was Samuel Morses achievement, but the discovery which motivated and allowed Morse to invent the telegraph was Joseph Henrys achievement. In Joseph Henrys own words: This was the first discovery of the fact that a galvanic current could be transmitted to a great distance with so little a diminution of force as to produce mechanical effects, and of the means by which the transmission could be accomplished. I saw that the electric telegraph was now practicable. I had not in mind any particular form of telegraph, but referred only to the general fact that it was now demonstrated that a galvanic current could be transmitted to great distances, with sufficient power to produce mechanical effects adequate to the desired object. Magnetic Engine Joseph Henry next turned to designing a magnetic engine and succeeded in making a reciprocating bar motor, on which he installed the first automatic pole changer, or commutator, ever used with an electric battery. He did not succeed in producing direct rotary motion. His bar oscillated like the walking beam of a steamboat. Electric Cars Thomas Davenport, a blacksmith from Brandon, Vermont, built an  electric car  in 1835, which was road worthy. Twelve years later Moses Farmer exhibited an electric-driven locomotive. In 1851, Charles Grafton Page drove an electric car on the tracks of the Baltimore and Ohio Railroad, from Washington to Bladensburg, at the rate of nineteen miles an hour. However, the cost of batteries was too great and the use of the electric motor in transportation not yet practical. Electric Generators The principle behind the dynamo or electric generator was discovered by  Michael Faraday  and  Joseph Henry  but the process of its development into a practical power generator consumed many years. Without a dynamo for the generation of power, the development of the electric motor was at a standstill, and electricity could not be widely used for transportation, manufacturing, or lighting like it is used for today. Street Lights   The arc light as a practical illuminating device was invented in 1878 by Charles Brush, an Ohio engineer and graduate of the University of Michigan. Others had attacked the problem of electric lighting, but a lack of suitable carbons stood in the way of their success. Charles Brush made several lamps light in series from one dynamo. The first Brush lights were used for street illumination in Cleveland, Ohio. Other inventors improved the arc light, but there were drawbacks. For outdoor lighting and for large halls arc lights worked well, but arc lights could not be used in small rooms. Besides, they were in series, that is, the current passed through every lamp in turn, and an accident to one threw the whole series out of action. The whole problem of indoor lighting was to be solved by one of Americas most famous inventors. Thomas Edison and Telegraphy Edison arrived in Boston in 1868, practically penniless, and applied for a position as night operator. The manager asked me when I was ready to go to work. Now, I replied. In Boston he found men who knew something of electricity, and, as he worked at night and cut short his sleeping hours, he found time for study. He bought and studied Faradays works. Presently came the first of his multitudinous inventions, an automatic vote recorder, for which he received a patent in 1868. This necessitated a trip to Washington, which he made on borrowed money, but he was unable to arouse any interest in the device. After the vote recorder, he says, I invented a  stock ticker, and started a ticker service in Boston; had 30 or 40 subscribers and operated from a room over the Gold Exchange. This machine Edison attempted to sell in New York, but he returned to Boston without having succeeded. He then invented a duplex telegraph by which two messages might be sent simultaneously, but at a  test, th e machine failed because of the stupidity of the assistant. Penniless and in debt, Thomas Edison arrived again in New York in 1869. But now fortune favored him. The Gold Indicator Company was a concern furnishing to its subscribers by telegraph the Stock Exchange prices of gold. The companys instrument was out of order. By a lucky  chance, Edison was on the spot to repair it, which he did successfully, and this led to his appointment as superintendent at a salary of three hundred dollars a month. When a change in the ownership of the company threw him out of the position he formed, with  Franklin L. Pope, the partnership of Pope, Edison, and Company, the first firm of electrical engineers in the United States. Improved Stock Ticker, Lamps, and Dynamos Not long afterward Thomas Edison released the invention which started him on the road to success. This was the improved stock ticker, and the Gold and Stock Telegraph Company paid him 40,000 dollars for it, more money than he had expected. I had made up my mind, Edison wrote, that, taking into consideration the time and killing pace I was working at, I should be entitled to $5000, but could get along with $3000. The money was paid by check and Thomas Edison had never received a check before, he had to be told how to cash it. Work Done in the Newark Shop Thomas Edison immediately set up a shop in Newark. He improved the system of automatic telegraphy (telegraph machine) that was in use at that time and introduced it into England. He experimented with submarine cables and worked out a system of quadruplex telegraphy by which one wire was made to do the work of four. These two inventions were bought by  Jay Gould, owner of the Atlantic and Pacific Telegraph Company. Gould paid 30,000  dollars  for the quadruplex system but refused to pay for the automatic telegraph. Gould had bought the Western Union, his only competition. He then, wrote Edison, repudiated his contract with the automatic telegraph people and they never received a cent for their wires or patents, and I lost three years of very hard labor. But I never had any grudge against him because he was so able in his line, and as long as my part was successful the money with me was a secondary consideration. When Gould got the Western Union I knew no further progress in telegraphy was possible, and I went into other lines. Work for the Western Union In fact, however, lack of money forced Edison to resume his work for the Western Union Telegraph Company. He invented a carbon transmitter and sold it to the Western Union for 100,000 dollars, paid in seventeen annual installments of 6,000 dollars. He made a similar agreement for the same sum for the patent of the electro-motograph. He did not realize that these installments payments were not good business sense. These agreements are typical  of Edisons early years  as an inventor. He worked only upon inventions he could sell and sold them to get the money to meet the payrolls of his different shops. Later the inventor hired keen businessmen to  negotiate  deals. Electric Lamps Thomas Edison set up laboratories and factories at  Menlo Park, New Jersey, in 1876, and it was there that he invented the  phonograph, patented in 1878. It was in Menlo Park that he began a series of experiments which produced his  incandescent lamp. Thomas Edison was dedicated to producing an  electric lamp for indoor use. His first research was for a durable filament which would burn in a vacuum. A series of experiments with a platinum wire and various refractory metals had unsatisfactory results. Many other substances were tried, even human hair. Edison concluded that carbon of some sort was the solution rather than a metal. Joseph Swan, an Englishman actually came to the same conclusion first. In October 1879, after fourteen months of hard work and the expenditure of forty thousand dollars, a carbonized cotton thread sealed in one of Edisons globes was tested and lasted forty hours. If it will burn forty hours now, said Edison, I know I can make it burn a hundred. And so he did. A better filament was needed. Edison found it in carbonized strips of bamboo. Edison Dynamo Edison developed his own type of  dynamo, the largest ever made up to that time. Along with the Edison incandescent lamps, it was one of the wonders of the Paris Electrical Exposition of 1881. Installation in Europe and America of plants for electrical service soon followed. Edisons first great central station, supplying power for three thousand lamps, was erected at Holborn Viaduct, London, in 1882, and in September of that year the Pearl Street Station in New York City, the first central station in America, was put into operation.

In and Of Itself

In and Of Itself In and Of Itself In and Of Itself By Maeve Maddox A reader asks, Is the term in and of itself usually associated with a reward, complete: can the reward be either in or of itself or is the separate use insufficient. I had to puzzle over the question a bit. I think it is asking if the phrases â€Å"in itself† and â€Å"of itself† can be used separately to mean intrinsically instead of being lumped together as â€Å"in and of itself.† Yes, they can. in itself This game is  in itself an insult to anyone  who buys it. Privatisation is not  good  or bad  in itself.   The world knows that Russia currently has regular soldiers stationed within the borders of Ukraine, albeit not identified (which in itself is a breach of acknowledged rules of war).   of itself Of itself  the idea of the outflanking maneuver was neither new nor original. All change is  of itself  an evil, which ought not to be hazarded but for evident advantage.   Of itself, the plan  might  not  have been unlawful, but it could have had unfortunate repercussions. â€Å"A reward in and of itself† is a clichà © used in reference to some activity that brings little or no reward in terms of money or appreciation. For example: A person’s job can be a source of reward in and of itself. Making great music is a reward in and of itself. Our work in community building can be seen as a reward in and of itself. The expression may derive from the proverb â€Å"Virtue is its own reward.† The idiom â€Å"in and of itself† is the English version of Latin per se: â€Å"by itself.† Long used as an English adverb, per se means â€Å"by or in itself; without reference to anything else; intrinsically.† Although some modern speakers object to the use of Latin expressions as elitist, â€Å"in and of itself† is hardly an elegant replacement for per se. But it is popular: To the extent any state employee was involved in facilitating the escape, that is a crime in and of itself, and that will be fully prosecuted as a crime in and of itself, Cuomo said. [A certain financing measure] could be one part of a comprehensive plan to increase education funding, but it is not a solution in and of itself. A school plan such as an Individualized Educational Plan is insufficient documentation in and of itself to determine eligibility. â€Å"In and of itself† is one of those phrases like â€Å"each and every† and â€Å"part and parcel† that say the same thing twice. Usually it is enough to say â€Å"in itself.† I wouldn’t go so far as to condemn the expression altogether. Sometimes a speaker might want to use it as a form of emphasis. Generally speaking, however, it sounds stuffy and clichà ©d. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily!

Introduction and Rationale School counselors work with students in academic development, social and emotional skill development, and college/career development. Their work supports student success through education in these domains, improvement of skills, reduction of stress, and improvement in mental health functioning. As I read the article, School Counseling Outcome: A Meta-Analytic Examination of Interventions, I couldn’t help but realize the importance of continued research on the effectiveness of school counseling interventions. This article focuses on the effectiveness of an array of school counseling interventions and not solely on individual and group counseling. The primary aim of this research was to review various literature pieces that relate to school counseling and identify their outcome and implications to the practice of school counseling. In 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. The study examined whether relevant moderator variables influenced effect sizes. The pretest-posttest size was not significant, so moderator analyses were conducted on treatment control comparisons. Analyses of moderator variables indicated school counseling program activities or interventions varied in effectiveness A meta-analysis of school counseling outcome research found an overall effect size of .30. Students who participated in the interventions improved almost a third of the standard deviation more than their peers who did not receive the interventions. In other words, school counseling interventions have a larger effect size than aspirin for preventing heart attacks (ES of .06) and an equivalent effect size to sertoline (Zoloft) compared to placebo, for  treating major depressive disorder (ES of .31). (Whiston & Quimby, 2009). The use of meta-analysis offers some weakness on the research which is actually a common thing for meta-analytic researches. This results from the fact that the effect size’s quality is dependant on the quality of research and accuracy. Sampling inaccurate of ineffective research cases may also render the meta-analytic research weak due to the weakness of the researches sampled. The meta-analytic research may also be stronger due to the fact that it samples a mean of similar variables under various researches and thus providing an average that is a true representative of all researches. In order to improve the meta-analytic exercise it is good to first make an analysis of the article and ensure that they are classified appropriately and their content has high validity so that they may not negatively affect the analysis (Sexton, L.T., & Whiston, S., 1998). A meta-analysis of school counseling research (117 studies, 153 school counseling interventions, and 16, 296 students) found an overall effect size of .30. The authors found that students who participated in school counseling interventions tended to score on various outcome measures about a third of a standard deviation above those who did not receive the interventions. School counseling interventions produced quite large effect sizes in the areas of discipline, problem-solving, and increasing career knowledge. The effect sizes were smaller, but significant, related to school counseling interventions’ impact on academic achievement. Surprisingly little school counseling research was found related to individual counseling. Concerning guidance curriculum, small groups were more effective than interventions that involved entire classrooms. Outcome research reflects that group counseling can be effective with students who are experiencing problems and difficulties. School counselors can improve the climate in their schools. They can also draw from a vast array of interventions that will help students increase  their academic achievement (Brown, 1999). One intervention that has been used for more than a quarter of a century is behavioral contracts. Behavioral contracts must have specific objectives, set attainable short-term goals, be monitored regularly, allow for immediate reinforcement, and be adjusted when they are not promoting the desired change. Other direct interventions frequently employed by school counselors include study skills groups, time management training, classroom guidance units aimed at improving test taking skills, and achievement motivation groups. Achievement motivation groups are led by the counselor, but involve input from the teachers and support for increased achievement from the students in the group. When students have educational and career goals, they do better in school. Counselors can facilitate the development of educational and personal goals by engaging students in individual and group activities that focus on goal setting. Some school counselors routinely ask students about interests, educational plans, and occupational goals and record these in their portfolios as one way of emphasizing the importance of goal setting. Research supports what educators have long understood: parent involvement is an important factor in student achievement (Brown, 1999). Parents who have a high level of commitment to their children, set high standards, maintain a stable home environment, and support achievement, have children who do better in school. Counselors can involve parents through parent consultation, parent education classes that teach parents how to support their children in schools as well as parenting skills, and by advocating for parents and students when students are not treated fairly by the educational establishment. They can also help keep the parents of children who are having difficulty in school apprised of their children’s progress by encouraging teachers to communicate more frequently with parents than once per grading period. School counselors are under pressure to assist in the effort to increase student achievement. They can respond to this challenge by working to improve the school climate, using direct interventions such as teaching study skills and involving students in achievement motivation groups, and by increasing the involvement of parents in the educational process. As our culture and educational institutions change, school counseling practices are emerging to better meet the needs of today’s students. Brown, D (1999).

Is college education valuable beyond economic incentive Essay

Is college education valuable beyond economic incentive - Essay Example Though the economic incentive is the biggest reason for gaining college education, there are a lot of other reasons too which justify the cause of acquisition of college education. Hence, college education is valuable beyond economic incentive. Discussion Many students, after having education from high school, cannot imagine the benefits a college education may offer to them. To them the college life and the studies at college are threatening, the thought of getting difficult assignments at college upsets them and the possibilities of meeting new people during college life distresses them. Being a student at high school one value one’s friends and it is difficult to think about departing from them. But the best part of college life is that there is a great possibility of meeting new friends with similar interests, principles and comic sense as soon as one enters the college. College life gives experiences and memories along with knowledge and skills. The benefits of college do not end with the passing out of a student but remain for lifetime. The most important among all advantages of college education is the economic one. It is the degree of a college that makes a student eligible for having a high salary. However, students who have acquired college education gain a lot of other benefits from college education as well. So it can be rightly said that besides economic incentive, there are other benefits of college education as well. This essay will discover how college education is valuable beyond economic incentive. It is a fact that after getting a college degree the student finds a good job with high remuneration package but along with the financial benefit, college education also gives the knowledge and skills that are the basic requirements of a good job (Ramage et.al. 508-512). Students who acquire a college degree usually get jobs which pay them 100 per cent more than the jobs gained by secondary school graduates at their entry level. A student jus t after having a bachelor’s degree usually succeeds in gaining a job which pays him no less than $4000 per month. On the other hand, a student who has acquired only a secondary school diploma cannot get a job which pays him more than $2500 per month. After gaining a college degree, the possibilities of job availability also increases. In today’s age a good job vacancy in a good working environment is rarely found, but those who have a college degree usually get a good designation at a reputed establishment. Along with economic incentive, it increases the confidence of college graduates in their capabilities, whereas the secondary school graduates usually do not get the same chance (Ramage et.al. 238-252). Furthermore, because the number of college graduates is smaller as compared to the secondary school graduates, college degree holders have to face lesser competition than them. Usually college degree holders are hired by organisations as soon as they get their degree. In this way the precious time of highly educated college graduates is saved from being wasted in searching jobs. But on the other hand, high school graduates are always in search of work. Because of a college degree, a student is able to achieve top management positions in an organisation but an unqualified employee can only look after a group of equally unqualified colleagues. The achievement of top management position, because of a college degree, boosts one’s confidence and encourages him/her to achieve a further position in his/her professional career. After gaining a college degree a student understands the way s/he can improve himself/herself. By gradually improving oneself one becomes a specialist in one’

Explore the way in which one or more emotional state is elicited and Essay

Explore the way in which one or more emotional state is elicited and shaped by a particular film, focussing on the consequences of formal and stylistic choices for our emotional experience of the film - Essay Example These include hypnosis, repeated phrases, music and facial muscle movement. Of all the methods used in elicitation of emotions, films are the only easily standardized method and entail little deception that is mostly seen in other methods. Films also present a higher degree of ecological acceptability in that they combine both the visual and auditory stimuli. As a consequence of the combination, films easily elicit a variety of emotions. The ability of a film to evoke an emotion is then compared to other films (Plantinga, 2009, p.71). Films can also elicit various cognition patterns to the audience. General cognition such as memory, assimilation and meta-cognition are enhanced by the film. Most cognitive effects of films relates to the information presentation and the atmosphere induced by the film. It is a normal phenomenon for instance, violence film to elicit violence. The elaboration of this effect is related to the significant cognitive effects of the film. The film Crash elicits a variety of emotional state in the audience. The emotional states elicited majorly relates with the theme of the film and the characters’ interaction in the film (Coan & Allen, 2007, p. 52). Crash is a recent film produced in 2004. Paul Haggis is the producer, co-writer and also contributed to its direction. The film addresses two major concerns including racial tension and the social tension in Los Angeles, California. Crash was inspired by a real life experience where Haggis Porsche was suffered a carjacking in 1991 at Wilshire Boulevard (Villalba & Redmond 2008, p. 72) The characters for the story include a white attorney and the wife, a black detective who had a younger brother and a gang associates. There is a white racist police officer who annoys his more critical partner. It entails a Persian immigrant and an industrious Hispanic locksmith who is a family man. The films stand outs distinctively from other films in that is relatively

Materials Essay Example | Topics and Well Written Essays - 250 words

Materials - Essay Example This paper focuses on the advancement of â€Å"non-clinker green cement† through the utilization of cement kiln dust (CKD) and fly ash (FA) (Shah & Wang 16). CKD has incompletely calcified substances possessing hydraulic and cementitious qualities. In addition, sulfate, alkali, and chloride elements are high and may affect the quality of cement performance. FA, on the other hand, contains mostly vitrified alumina-silica melt and minute amounts of crystalline elements such mullet, quartz, and mica (Shah & Wang 16). Previous research indicates that appropriate blending of CKD and FA may yield a cementitious matter, thus changing waste into useful substances. This paper looks at three methodologies of activating the hydration of CKD-FA binders. These are mechanical, thermal, and chemical. Chemical activation involves the addition of 2 % and 5% sodium hydroxide to the CKD-FA systems. Thermal activation entails curing at temperatures between 38 and 50oC in comparison with curing at 24oC. The study utilizes various compositions of FAs and CKDs. Finally, mechanical activation engages various grinding regimens ranging from simple, vibratory mill, ball mill, combined (ball mill and vibratory mill grinding) and grinding aid in the form of high-speed mixing (Shah & Wang 17). The process realizes that various activation methods give various strengths at different compositions of CKD and FA. For example, highest strength arises from the addition of 2% NaOH to a binder comprising of equal quantities of CKD and FA cured at 38oC (27 MPa (4000 psi) at age of 56 days) (Shah & Wang 17). Grinding activates the materials both chemically and mechanically. This paper, therefore, concludes that estringitte is the key crystalline hydration outcome of CKD-FA, vibrator grinding for four hours is the most efficient mechanic-chemical activation technique. Addition of NaOH hastens chemical disbanding but lowers estringitte development in hydration of the binder. Overall, utilization of

Chapter 4 Assignment Example | Topics and Well Written Essays - 500 words

Chapter 4 - Assignment Example For this to succeed, communication must be present as it facilitates identification of goals, request making, and problem solving. Collaboration allows mutual support as well as the ability to share knowledge appropriately. The chapter maintains that the most important aspects of collaboration include parity, trust, respect, and establishment of common goals. We also learnt that there are several communication styles that can be used and incorporate unilateral, directional, and transactional where transactional method is preferred since it favors a two way mode of communication. However, there are several barriers that affect communication and collaboration. These include cultural background, gender, age, interests and experiences. To eliminate these barriers, both the teacher and the family need to exercise strong communication skills. It is more helpful to ensure that both verbal and non-verbal forms of communication are exercised appropriately so as to eliminate the barriers. The barriers are responsible for miscommunication. Specifically, the teacher should ensure that they avoid quick fixes to certain problems, avoid minimizing feelings by using false reassurances, and ask the most appropriate questions. When barriers emerge, problem solving strategies are used to retaliate. Such strategies include avoiding emotional responses and relying on a step to step procedure. This process incorporates identification of the problem, generation of potential solutions, evaluation of those solutions, implementation of the selected solution, and evaluation of the so lution. These steps also ensure that a conflict is resolved in a constructive manner. There are several myths thought to reduce miscommunication that include more communication being better, communication being a natural ability, and open communication being effective in solving problems. We also

Financial reporting Assignment Example | Topics and Well Written Essays - 1000 words

Financial reporting - Assignment Example Financial statements, prepared on the basis of historical cost accounting method, do not provide a fair and true presentation of equity’s performance or future prospects, if capital is inadequately maintained (Charnes, 1976). Moreover, critical assessment of equity’s performance by studying ratios, such as, return on capital employed, will be useless if capital is undervalued, profit is overstated and values of assets are misinterpreted. These sometimes occur because of historical cost accounting. The limitations have been summarized as follows: Overestimating and valuing profits by undercharging depreciation on the basis of historical cost and recording sales cost at original cost of inventories, may result in the reduction of an entity’s capital because of high taxation charges and distribution (Belfo and Trigo, 2013). This accounting approach toughens the task for analysts and shareholders of evaluating and assessing the ability and performance of management. This is precisely because variations in the situation of the current market are not considered in historical valuation approach. Then, owner of the entity tried to restock his inventory and realized that the cost of replacement was $2,200. They did not have enough cash to restructure to the pre-sale condition. The difficulty escalated due to the fact that the owner was unable to differentiate between the profits generated from holding the inventory for a particular time period before selling it and the revenue that was generated through trading. Had the company matched the cost of replenishment against revenue, they would have realized a profit of $300. If this excess proceed had been withdrawn, it would have left the company with $2,200, which could be used for the purpose of inventory replacement. Thus, this example suggests the fact that historical accounting can be misleading to the user of the information (Bakar and Said, 2007). The application of general price index under this method is

Ethical Dilemma Essay Example for Free

Ethical Dilemma Essay All healthcare professionals take the Hippocratic Oath, in this oath it states that, â€Å"I will respect the privacy of my patients, for their problems are not disclosed to me that the world may know. † (Miles, S. H. (2004) There are many different versions of this oath but the concept and meaning behind it remains unchanged. This section of the oath was designed in part to protect patient’s privacy. Building and establishing a relationship based on trust with our patients is essential in the foundation in providing good quality care. This allows our patients to feel comfortable discussing anything with us and knowing it will be kept confidential. In nursing ethics play a critical role, breaching confidentiality can have a magnitude of ethical consequences including legal issues and patients no longer trusting medical professionals. As healthcare professionals, we are faced with situations daily with an array of ethical, legal and professional responsibilities where we have to use our own personal judgments to protect both our patients but the public as well. As a legal concept, confidentiality can be said to be an obligation on one person to uphold the privacy and security of another person’s information. This legal obligation arises in several areas: under common law; in contract law where these terms can be express terms or implied; and as a general legal duty where it could be considered negligent if harm results as a consequence of a breach of confidence. † (Cornock 2011). Confidentiality does not override ethical principles in all cases, and some cases it would be considered unethical to not break confidentiality when a legal requirement makes a breach mandatory. Nursing encompasses the prevention of illness, the alleviation of suffering, and the protection, promotion, and restoration of health in the care of individuals, families, groups and communities. † (ANA 2010) This duty to such an extensive population can pose obvious conflicts both professionally and personally. Does the right to privacy of our patient over ride a safety concern to our community? In nursing practice nurses are able to use a variety of ethical theories and apply these to patient situations. â€Å"Deontologic theories hold that you are acting rightly when you act according to duties and rights. In other words, duties and rights are the correct measuring rods for evaluating a course of action and its outcome. † (Purtilo 90) People who follow this theory in their clinical practice have very consistent decisions as these are based on their duty. It becomes the healthcare provider’s duty and obligation to respect and protect a patient’s confidentiality. By breaching patients confidentiality breaks the trust that was built between patient and provider. â€Å"Utilitarianism, an act is right if it helps to bring about the best balance of benefits over burdens, in other words, the best â€Å"utility† or consequences overall. (Purtilo 92) This theory would be basing a decision on whether or not the action (breaking or not breaking confidentiality) brings out the best outcome. However, sometimes the best outcome isn’t legally correct. In the article â€Å"Bioethics on NBC’s ER: Betraying Trust or Providing Good care? When is it ok to Break Confidentiality? by Pamela Nathanson, we see a time when a healthcare provider is faced with an ethical dilemma on whether to break a patient’s confidentiality in order to protect the patient and the community. Like with any ethical dilemma there are steps that can be used to help a healthcare provider make a decision or help solve the problem. These steps include: 1) gather relevant information, 2) identify the type of ethical problem, 3) use ethics theories or approaches to analyze the problem(s), 4) explore the practical alternatives, 5) complete the action, and finally 6) evaluate the process and outcome. (Purtilo pg 102-110) Using this process healthcare professionals are able to make decisions to tough ethical dilemmas that come up in their clinical practice. I agree with Ms. Nathanson that the parents needed to be informed of their daughters diagnosis in order to prevent harm to the patient and ensuring the patient receives proper follow up care. I also agree that the school did not need to be informed of who the student was but to inform the school that it had come to the attention of medical professionals about sex parties going on in the school. By choosing this way you are ensuring the safety of your patient and the community with causing the least amount of damage. If you disclosed to the school who the student was as the nurse did in the show you risk unnecessary harm to your patient. Ethics committees are made up of members that include a lawyer, an ethicist, quality improvement manager, a nurse, a clergyman, a physician and an individual from within the community. By joining together these members with diverse backgrounds, experiences and perspectives they are able to come together to help develop different alternatives and discussions regarding ethical dilemmas that may arise. They are able to help provide recommendations in complex and challenging ethical situations. However, these decisions are not law but they do hold certain significance on influencing a judge or jury. (GCU) As long as health care deals with life and death, ethical dilemmas will come into play for medical professionals everywhere on a daily basis. Due to the nature of the medical profession, complex situations will require fast acting decisions that can be life changing for all parties involved. It is important to have a thorough knowledge of ethical theories and principles in the health care industry so medical professionals are prepared to make these decisions when they are faced with ethical dilemmas.
