Police Profiling essays

Police Profiling essays During the Civil Rights movement, thousands of blacks were arrested and beaten by police. Toady we face the same problem, police departments gets more and more complaints from black citizens. In New York City in 1999 a street merchant was mistakenly shot to death because a cops thought he pulled out a gun. In New Jersey four college basketball players were heading for tryouts at a college, when stopped the driver couldnt get the van into park the two officers opened fire. Luckily nobody was hurt. Racial Profiling is one of the most volatile civil rights issues in the U.S. and even the most successful African-Americans are not immune to it (Most 89). Recent research shows that crime is down, but it also shows that police target blacks more than whites. Racial subjects attract attention from Civil rights groups, Politics, and the locals. What do they know, were they there when the Cops shot the merchant or the college players? Minorities say theyre more worried about the cops than the crooks (CannonI dont want my sons to be victims of police brutality (Leo 16). Some cant find a reason why blacks are stopped and frisked more than whites, but the blacks coined the phrase DWB is the cause. DWB stand for Driving While Black (Drummond 61). With campaigns going on Al Gore and Bill Bradley fell over them selves to become commander in chief of the forces against racial profiling. Bradley promised an executive order eliminating racial profiling at a federal level, Gore raising the ante to a notional law outlawing racial profiling altogether (Chua-Eoan). The Governor of New Jersey, Chr...

BUSINESS ECONOMICS Essay Example | Topics and Well Written Essays - 1750 words

BUSINESS ECONOMICS - Essay Example Open market operations involves the buying back or selling of government securities. Of the government wants to increase the supply of money it will buy back the securities it has sold to financial institutions in exchange of currency that will then be circulated in the market in the form of investments or lending. If the government wants to decrease the money supply it will sell its securities and holding onto the money that was previously in circulation. Another way to control money supply is to adjust the rate of lending at which the banks can obtain loans from the central bank or other banks. Higher rate will result in low borrowing and hence tightened money supply and vice versa. Lastly, Cash Reserve requirement is also adjusted in order to control money in circulation. Cash reserve is the amount of funds that the financial institutions are required to keep aside. This is a percentage of the total deposits and higher cash reserve requirement allows banks to lend out less funds. Similarly lower cash reserve requirement enables banks to have more funds to lend out. Unconventional tools of money supply include the central bank’s commitment to keep rates low in the future. Another means is to adjust the central bank’s assets to provide ease in credit through the change in different rates and prices. Third unconventional way is lower the policy rate to zero by supplying reserves that are more than the required rate (Highered.mcgraw-hill.com, 2011). Money supply is a crucial aspect that determines the value of currency and inflationary measures. Conventional ways are the standard means for the central bank to control money supply. However, if the economic conditions do not permit the central bank to use the conventional means they resort to unconventional means which are effective but not good for the economy in the long run due to their unpredictable and risky nature. (b) In a 2012 study the International Monetary Fund (IMF) reported that the fiscal

MT140 Unit 4 Assignment Research Paper Example | Topics and Well Written Essays - 250 words

MT140 Unit 4 Assignment - Research Paper Example 2. Promoting an existing manager is a very intelligent move as the manager would be aware of the business and its policies. Normally it takes time for new managers to adjust to the philosophy and culture of an organization but promoting an existing manager would avoid such problems. It would also be easier for an existing manager to communicate as he would be familiar with some of the location managers (Samovar & McDaniel, 2010). 3. The CEO should be making these decisions because the new coordinating manager would be directly working under him. He would be responsible for communicating between the location managers and the CEO so the CEO must choose a person with great communication skills (Samovar & McDaniel, 2010). The CEO must realize the importance of the job as it would link him to the rest of the team and should pick the candidate himself based on the qualifications and skills. 4. When the new position is created then it will not change the level of authority for the CEO and the upper management however the middle and lower management will be affected. The CEO would require the location manager to report the coordinating manager and they would have the privilege of directly communicating with the CEO taken away from them. They would not be able to communicate with the CEO on regular basis making them more reliant on the coordinating manager (Samovar & McDaniel, 2010). On the other hand, the coordinating manager will have a greater say in important matter and in some cases even over the senior managers of the

Cutaneous Myoepithelioma | Case Study

Cutaneous Myoepithelioma | Case Study TITLE: Cutaneous myoepithelioma: A case report of an unusual and recently recognized entity ABSTRACT: Myoepitheliomas and mixed tumors were only recently recognized to occur primarily in soft tissue, and only small case numbers have been described. The present case is of 25-year-old male who had solitary, painless mass over right middle finger, measuring 3cm in greatest dimensions and light microscopy revealed a tumor composed of a mixed population of spindle, epithelioid and plasmacytoid cells arranged around a central chondromyxoid stroma. No definite diagnosis could be reached on this morphology and initial diagnosis of benign mixed stromal tumor was considered. Immunohistochemistry(IHC) was performed and the tumor showed strong positivity for Calponin and SMA, Ki-index showed low index, weak and focal positivity for S-100 and negative for Pan-CK. The final diagnosis of benign myoepithelioma was entertained. Keywords: Myoepithelioma, Cutaneous, Soft tissue INTRODUCTION: Myoepithelioma of the skin and soft tissue is a newly recognized entity only ten years ago with fewer than 50 case reports. It has characteristic histopathologic and immunohistochemical features, which need to be differentiated from a variety of tumors CASE REPORT: Case history: A 25-year-old male presented with a solitary, painless mass over right middle finger, measuring 3cm in greatest dimension since 6months. There is no increase in size and overlying skin is smooth and unremarkable. The mass is firm, non- tender and mobile. X-ray showed a soft tissue mass with underlying bone unremarkable. Gross: Multiple tissue bits aggregate measuring 3Ãâ€"2Ãâ€"1cm and skin flap measuring 2Ãâ€"1cm. Light microscopy: Revealed a tumor in the superficial dermis composed of a mixed population of spindle , epithelioid, and plasmacytoid cells arranged around a central chondromyxoid stroma. No definite diagnosis could be reached on this morphology and diagnosis of benign mixed stromal tumor was considered. Immunohistochemistry(IHC): IHC was performed and showed strongly positive Calponin and SMA. S-100 was weak and focally positive. Pan CK was negative. Ki 67 revealed low index (2%). The final diagnosis of Benign myoepithelioma was entertained. DIFFERENTIAL DIAGNOSIS The primary differential diagnoses considered were extraskeletal myxoid chondrosarcoma (EMC) and ossifying fibromyxoid tumor (OFMT). EMC typically shows a multinodular growth pattern with cords of cells in a myxoid matrix. The tumor cells in EMC are more spindled than those of myoepitheliomas. S-100 protein and epithelial markers are expressed in a minority of EMC and usually only focally, while both the markers are often extensively expressed in myoepitheliomas. OFMT is a lobulated tumor surrounded by a rim of metaplastic bone. The tumor cells are mostly pale-staining ovoid to round cells. Approximately 70% of OFMT show positivity for S-100 protein and vimentin and 50% of tumor cells are positive for desmin. The tumor cells in OFMT are rarely positive for epithelial markers and GFAP. Myoepitheliomas are generally negative for desmin, nearly half positive for GFAP, and nearly always show positivity for keratin and S-100 protein.[1] Other tumors that should be differentiated are, Epithelioid benign fibrous histiocytoma that usually shows a superficial dermal tumor with a well-developed epidermal collarette. Spitz nevus is characterized by a junctional component, nesting and maturation of tumor cells. In epithelioid sarcoma, multiple tumor nodules around central necrosis or even myxoid degeneration are often seen. More morphologic uniformity is observed in epithelioid sarcoma over myoepithelioma. Moreover, approximately 90% of epithelioid sarcoma are positive for vimentin, cytokeratin, and EMA, and around 60% are positive for CD34, but are generally negative for other markers typical myoepithelial differentiation (S-100 protein, GFAP, myogenic markers). Cellular neurothekeoma consists of nesting of tumor cells, and are consistently S-100 negative.[2] COMMENT Tumors comprised mostly of myoepithelial cells without obvious epithelial differentiation are designated myoepitheliomas.[1] Neoplasms of myoepithelial cells can occur in a pure form as myoepitheliomas or in association with glandular structures as mixed tumors.[2] Myoepitheliomas of the skin and soft tissue were recognized only 10 years ago.[3] Myoepithelial cells can exhibit dual epithelial and myoid differentiation. They may also show divergent metaplasia, including squamous, adipocytic, bone and cartilaginous differentiation.[4,5] As a consequence, proliferating myoepithelial cells in neoplasms display a variety of histologic and immunohistochemical expression patterns. It has been postulated that cutaneous myoepitheliomas are related to mixed tumors of skin and that soft tissue myoepitheliomas are derived from deeply located adnexal structures. Cutaneous myoepitheliomas of the head and neck may be derived from salivary gland tissue, as has been reported in two parotid gland myoe pitheliomas presenting as infra- auricular subcutaneous masses.[6] Therefore, the possibility of an underlying primary salivary gland neoplasm should be considered in myoepitheliomas presenting in the head and neck. Myoepithelial tumors were described only recently in soft tissue, and, to date, fewer than 50 cases have been reported. Kilpatrick et al [3] reported a study of 19 patients with mixed tumors and myoepitheliomas of soft tissue in 1997. Michal et al [7] reported 12 additional cases of myoepitheliomas of the skin and soft tissues in 1999, Hornick and Fletcher conducted a study of 14 cutaneous myoepitheliomas. There were 11 males and 3 females. The study indicated that cutaneous myoepitheliomas occur with peaks in childhood (7 patients were between 10 and 20 years of age) and middle age and are most common on the extremities, in contrast to mixed tumors of the skin, which typically occur on the head and neck in middle aged or elderly adults.[1,3,4] Myoepitheliomas of soft tissue are often lobulated, and the most frequent architectural pattern is reticular or trabecular with chondromyxoid or hyalinized stroma. These lesions display the same wide range of histologic features as those of salivary gland origin. Many tumors are heterogeneous, containing an admixture of epithelioid and spindled cells, reticular areas merging with solid areas, at least focally prominent stroma, and occasional foci of cartilaginous or osseous differentiation. [8] A small subset of tumors approximately 10% are predominantly solid proliferations of spindled or plasmacytoid myoepithelial cells. Occasional tumors display features of so-called parachordoma, namely, large epithelioid cells with eosinophilic epitheliomas. Initially, myoepitheliomas were only recognized to contain spindled or plasmacytoid cells growing in solid sheets. [9]Current classifications therefore include all of these patterns within the spectrum of myoepithelioma, simply separating those tumors with ductal differentiation into the mixed tumor category.[10,11] Whereas some investigators allow up to 5% or 10% ductal differentiation in myoepitheliomas, others classify tumors with any ducts as mixed tumors. In any event, it is now widely thought that myoepitheliomas and mixed tumors fall along a spectrum of tumors with overlapping histologic appearances and similar clinical behavior. Because the immunophenotype of these lesions overlaps with myoepithelioma, and otherwise typical myoepithelioma s can show focal areas with â€Å"parachordoma†-like features, it is becoming increasingly clear that parachordoma probably falls within the spectrum of myoepithelioma of soft tissue, as is reflected in the new WHO classification.[11] The only apparent difference in immunophenotype is GFAP and SMA negativity in parachordomas, because few cases of parachordoma have been studied and only about 50% of otherwise convincing soft tissue myoepitheliomas are GFAP positive and only around 40% are SMA-positive, then this distinction seems very questionable. Awareness of the wide morphologic range of myoepitheliomas is necessary to perform confirmatory immunohistochemical stains and thereby to arrive at the correct diagnosis.[12] In salivary glands, myoepitheliomas are generally positive for cytokeratins and S-100 protein, whereas immunostaining for actin and GFAP is variable. We therefore required immunoreactivity for either keratin or EMA, in conjunction with detection of S-100 protei n or myogenic markers, for the diagnosis of myoepithelioma and inclusion in this series. Neoplastic myoepithelial cells of all morphologic types often expressed myogenic markers.[13] As has been reported in the salivary gland, we found calponin to be the most sensitive myogenic marker, staining 86% of tumors, whereas SMA stained 36% and desmin only a small subset (14%). Interestingly, the basal cell/myoepithelial marker p63, which has shown utility in the differential diagnosis of carcinoma of breast and prostate due to the staining of myoepithelial or basal cells in in situ lesions, appears to be detectable in only one fourth of soft tissue myoepithelial tumors. Immunostaining for p63 is not specific for myoepithelial tumors, however, as this antigen has also been reported in other neoplasms, especially squamous cell and urothelial carcinomas.[13,14] Nonetheless, detection of p63 expression may provide helpful supportive evidence of myoepithelial differentiation in the proper morph ologic context. CONCLUSION: Cutaneous myoepitheliomas are relatively rare. Pathologists play an important role in reaching to accurate morphological diagnosis. Myoepitheliomas should be considered in the differential diagnosis of cutaneous and soft tissue tumors. Immunohistochemical study may aid in the diagnosis. Although most cutaneous and soft tissue myoepitheliomas behave in a benign fashion, there is a significant risk for local recurrence and a low metastatic potential. Wide excision with safe surgical margins and regular follow-up are crucial for the management of cutaneous and soft tissue myoepitheliomas. References: 1. Hornick JL,Fletche CDM.

World War II: Pearl Harbor & The Pacific War Essay -- history, world w

Chaos and continual disorder encompassed the people across the globe in the years prior to the declaration of war between the Axis and Allied powers in 1939. The Great Depression that had struck soon after the First World War left much of the world unemployed and desperate for relief. Nationalism swept through Germany in response to the terms of the Versailles Treaty that ended World War I. China and Japan had been at war since Japanese troops invaded Manchuria in 1931. Germany, Italy, and Japan began multiple invasions and occupations of nearby countries. When they received no meaningful consequences for their aggressive actions, they felt emboldened and World War II began. In the midst of war and the growing totalitarian aggression, the United States passed several Neutrality Acts in an attempt to avoid involvement in another global war. Efforts to stay isolated from global conflict would lead to growing tensions between the main powers resulting in a rather inclusive war. After a vicious attack on their own home front staged by the Japanese, the United States catapulted into World War II. Over the course of the next six years the United States engage in continuous battles with Germany, Japan, and Italy on various fronts in Europe and the Pacific which necessitated a larger fighting force. Men like Raymond Barron Chavez courageously served as a naval serviceman during the war. Through his accounts on the Pearl Harbor attack and battles in the Pacific, we learn the first hand details of World War II. World War II reveals that leaving particular issues unresolved in terms of war will most likely lead to another one. The seeds of World War II in Europe began to sprout due to the Treaty of Versailles that ended World War I.
