Roberto Mussolini essays

Roberto Mussolini essays The moment I heard the name Rudolph Valentino it immediately caught my attention. His name reminded me of a combination of a fashion designer and a red nosed reindeer. When I heard who he actually was, I was even more intrigued. He was one of the main heartthrobs of the 1920s. Being a hopeless romantic myself, this description caught my attention. The only thing I had known previously about him before doing my research was that he was a good looking, enormously admired, actor. I wanted to find more out about this man. I wanted to take a look into the life of a 1920s movie star. I thought that the search process on Rudolph Valentino would be fairly easy. I thought I would go to Yahoo, type in his name, and hundreds of websites would appear at my fingertips. It turns out it wasnt that simple. Four days before the report was due, my Internet cable connection stopped working. I had heard that the system hadnt been working properly lately and I figured it would clear up in a day or so. A day goes by and I decide to bug my parents about trying to get it to work. They call the computer company and their advice was, wait a day or so. I was left with no idea who Rudolph Valentino is, two days to write a report and no Internet to find any information about him. I then resort to going to West Bloomfield Public Library. I always find it hard to find what I am looking for at libraries so it was my last resort. I walked over to the section that had books about movies stars. I looked in books for the name Valentino. About 5 books had information so I picked the three that looked the best. I didnt have much time there because I needed to finish my Literary Analysis that night. Therefore, I didnt look very closely at exactly how much information was in those three books. When I got home I looked in the books and realized there was about enough information in those books to write a half...

Theory and Practice Research Paper Example | Topics and Well Written Essays - 1500 words

Theory and Practice - Research Paper Example For instance, studies in mathematics and sciences have shown that better performance emanates from depth rather than breadth (Cogan & Schmidt, 2002). Teaching is termed successful, if students learn what has been taught. Therefore, this paper focuses on what students are learning. It is subdivided into three sections: the role of assessment in the context of instruction, most essential and long lasting concepts the students should be taught and, finally, the role of assessments. Beginning from looking at the role of assessment in the context of instruction, assessment is supposed to be developed to fit the learning targets set for the students in order to be supportive to the students. It should be consistent with methods of instruction as poor connection among learning targets. Instructions and assessment only amount to more than confusion and frustration leading to anger and despair. Learning is accompanied by a cognitive change and behavioral experience among people. Contrary to w hat teachers believe, much of what students learn come from experiences outside school rather than from classroom. Therefore, an ideal relationship should be established among learning targets, instructions and assessment. ... In determining what students are to learn, it best begins with one’s knowledge of the subject combined with their values as an educator. No time is sufficient for a student to learn all that is required of them. Factory model of schooling in which teachers rush to cover a topic after topic leaves little or no time for internalizing ideas and making the concepts gained a solid part of the student’s cognitive and behavioral experience. Students retain little of what is taught in courses that is based on content coverage other than deep understanding of the concepts. In the event that students cannot learn all that is taught, wise choices ought to be made about what is possible in a given fixed time. Learning goals and learning objectives are the terms used as labels for statements about what teachers want students to learn. Learning goals reflect ultimate aims of schooling; whereas, learning objectives focus more on knowledge and skills that help students attain their goa ls. The term subject areas are used to refer to conventional titles of content taught in school, while discipline refers to fields or study and work. Four questions can assist in framing learning goals for teaching and these include: evaluating the dimensions of the subject are to be taught, the chief aspects of these subject areas to students of a certain year and the level of sophistication. Students can, hence, continue working on the broad goals after moving to other teachers. The third question is the knowledge and skills within the discipline that will help students understand the working of other people in the field, the knowledge of people in the field that makes them successful and their

The Theoretical Foundations of the Old Diplomacy Are Outdated Essay

The Theoretical Foundations of the Old Diplomacy Are Outdated - Essay Example ..’ Its practice dates back to the earliest known civilizations, beginning, according to Hamilton & Langhorne (2011, p.7), when early human societies realized that it makes for much better peace and harmony to listen to a message rather than to eat the messenger. Political entities, even in those times, recognized the need to co-exist with one another, as well as to enter into unions and forge alliances - in defence or offence - against common threats and perceived enemies. Early diplomatic practice, which may have begun in the ancient Near East around the middle of the third millennium B.C. (Hamilton & Langhorne, 2011, p.8) provided the framework for this. The practice of diplomacy has evolved over time, with two broad classifications emerging: the ‘old diplomacy’, practiced up to the early part of the twentieth century and the ‘new diplomacy’, which succeeded it. Theoretical Foundations of the ‘Old Diplomacy’ The gradual evolution of ea rly political entities (clans, villages, tribes, etc.) over millennia gave rise to the birth of sovereign nation states. The need to maintain an orderly structure of international relations in order to secure the growing prosperity of the nation states, in other words, the necessity for diplomacy between expanding political entities with often competing interests saw the emergence in Europe of what has been loosely described as the ‘old diplomacy’. It had, according to Nicolson (1954, p.73-77), five principal features, as follows: 1. Europe was conceived as the most important of all the continents. The greatest nations of Europe (Germany, Austria-Hungary, Russia, France and Britain) were regarded as the ‘Great Powers’ while other nations had to wear the toga of ‘Minor’ or ‘Small Powers’ No war, it was believed, could become a major global threat unless one of the five great European powers got themselves embroiled in it. Thus Europ e was seen as holding the balance between war and peace on a general scale. 2. The ‘Great Powers’ were seen as pre-eminent over the ‘Small Powers’, having wider responsibilities, holding more prominent and sophisticated interests and possessing greater resources, whether in money or armaments. The ‘Small Powers’ were ranked in order of their strategic importance and position, their value as markets or sources of raw materials and their relation to the balance of power. 3. The ‘Great Powers’ arrogated to themselves the common responsibility for exercising oversight functions in regard to the conduct of affairs between the ‘Small Powers’ and the preservation of peace and amity amongst them, considering themselves invested with the authority to intervene directly and by force of arms where necessary, in disputes and disagreements between these ‘Small Powers’. 4. To secure and uphold the hegemonic structure th us put in place, there was the need to establish in every country a professional diplomatic service and an associated diplomatic corps built on a more or less identical model, with common standards of professional conduct. This made it possible for Ambassadors of various countries to relate to each other with mutual respect and confidence, even when the nations they represented were engaged in acrimonious disputes or warfare. 5. Following from the above, the rule was also established that negotiations between states should be

America Air Pollution Essay Example | Topics and Well Written Essays - 1000 words

America Air Pollution - Essay Example The air pollution was in the first industrial revolution because of massive amounts high-sulfur coal usage in the production process. Great amounts of industrial production largely used high-sulfur coal hence producing abundant SO2 into the air. Air pollution specifically in the cities is not a new encounter. In the Middle Ages, using coal in the cities had escalated. The challenge of poor quality of urban air as early as in the sixteenth century depended on the use of coal. After the first industrial revolution, the air pollution problem formed and developed during the second industrial revolution as a form of â€Å"smoke†. Many industries were located in the cities and towns. The fumes from these industries and the coal from domestic heating in the home made the levels of air population in the urban region be high. In times of foggy situations, the level of pollution increased leading to the formation of urban smogs (a mixture of fog and smoke). This made the cities in America to be brought to a halt, interfering with the traffic and causing the rates of death to increase dramatically. The influence of pollution on vegetation and building was obvious. In the year 1960 to 1990, the congress of the United States enacted a number of clean air acts that were useful in strengthening the air pollution regulation. These initiatives were followed by many states in the United States. The Clean Air Act established some numerical concentration limits of th e basic air pollutants thus giving the reporting and mechanisms of enforcement.

Central Giant Cell Granuloma (CGCG) Case Study

Central Giant Cell Granuloma (CGCG) Case Study ABSTRACT: Central giant cell granuloma (CGCG) is an intraosseous lesion which occurs as an uncommon benign condition in jaws. WHO defines this intraosseous lesions as â€Å"a lesion that contains multiple foci of haemorrhage, consisting of cellular fibrous tissue and there is trabeculae of woven bone. It may become aggressive leading to expansion and perforation of the cortex. Mobility and displacement of the involved teeth and root resorption are often observed. Here is a case report of an 18 year old female patient who is diagnosed with an aggressive type of CGCG. KEYWORDS: Central giant cell granuloma, granuloma, giant cell granuloma, giant cell lesions. Introduction Central giant cell granuloma (CGCG) is a benign proliferation of fibroblasts and multinucleated giants cells that almost exclusively occurs within the jaw. It commonly occurs in young adults showing a female predilection.1 CGCG rarely occurs in areas elsewhere other than the jaws, like maxillary sinus, temporal bone, cranial vault and other bones of the craniofacial complex.2 It was thought that CGCG is a reparative lesion as it develops in response to intrabony hemorrhage and inflammation secondary to trauma. However, it can be considered as an aggressive lesion because of its aggressive behaviour as seen in the present case. Case report A 18 year old female patient, presented with a painful swelling over the lower border of mandible of 3 months duration. The patient had a history of trauma 6 months back with fractured 31. On extra oral examination, gross asymmetry of face was seen with a diffuse swelling of approximately 34 cm size on chin. Lymph nodes were not palpable. Local examination revealed a diffuse swelling extending mentolabial sulcus, inferiorly below the lower border of mandible and antero-posteriorly extending from the midline to the level of corner of mouth both side extending 1.5cm size. Colour over the surface appeared normal; no ulceration or discharge from the swelling was seen. Surface of the swelling was smooth, consistency was hard. The swelling was non – fluctuant; No rise in temperature, no pulsations were felt. The swelling was tender on palpation. On intraoral examination, tenderness on palpation was evident in relation to left mandibular canine and first premolar. No lingual expansio n. Based on the history given by the patient and the clinical examination, a provisional diagnosis of traumatic bone cyst in relation to anterior lower border of mandible was given. However, radiographic examination was suggested to confirm the provisional diagnosis. Orthopantomographs demonstrated normal anatomic hard tissue structures with a diffuse radiolucency seen in the mandibular anterior region crossing the midline , measuring approximately 3 cm x 3.5 cm, extending medio-laterally from 34 to 44 and supero-inferiorly from the apex of mandibular anterior extending to 1.5 cm below the level of inferior border of mandible suggestive of expansion of inferior border of mandible with sclerotic border on superior aspect and no sclerotic border inferiorly. Based on the clinical and the radiographic examination, differential diagnosis of odontogenic keratocyst, ameloblastoma, osteosarcoma and central giant cell granuloma were considered. Histopathological evaluation of the excisional biopsy specimen showed the presence of connective stroma containing numerous young fibroblasts as well as multinucleated giant cells. Trabeculae of osteoid and woven bone were also seen in the periphery. Numerous extravasated RBCs were present within the connective tissue stoma. These findings are suggestive of CGCG, but in order to differentiate this from brown tumor of hyperparathyroidism, we carried out blood investigation, to find the serum calcium, serum phosphorus and alkaline phosphatase levels, which are found within normal limits. Based on the above histological and investigational findings, a diagnosis of CGCG was given. Discussion Central giant cell granuloma is a benign intraosseous lesion of the jaws. Jaffe in the year 1953, described this intraosseous lesion as â€Å"central giant cell reparative granuloma†.1 Since there is not reparative process, the name â€Å"reparative giant cell granuloma† was denominated. The etiology and pathogenesis of CGCG is unknown, but the granulomatous process is induced by an exacerbated reparative process due to trauma and haemorrhage.3 Giant cell granuloma is considered as a benign proliferation of fibroblasts and multinucleated giant cells that occurs almost exclusively within the jaws. It is seen in all age groups ranging from 2 to 80 years, but more than 60% of the cases occurs under the age of 30 years.5 Although Sex distribution varies in different reviews, CGCG show female predilection with a prevalence of almost twice that of males.4 It commonly occurs in mandible ,anterior to the first molar ,often crossing the midline. It occurs in the short tubular b ones of hands and feet and also in the other bones of facial skeleton and cranial vault but rarely occurs in craniofacial bones. 6 It may be peripheral or central. The peripheral lesions occur as pedunculated or sessile lesions where the central lesion is endosteal. Females, children and young adults have more predilection since the female male ratio is 2:1.7, 8 The main etiological factor for this lesion is trauma. The lesion progresses by accumulation of tissue which due to slow and continuous haemorrhage of multicentric nature as a result of trauma and defect in the capillaries. 9 Though the CGCG is a benign lesion, it occurs as aggressive and non-aggressive types. The aggressive type shows painful and rapid growth occurs in younger patients and often involves cortical perforation and root resorption and may recur. The non-aggressive type is of slow growing, asymptomatic, without any resorption or perforation of the involved teeth and it never recurs.10 The signs of CGCG are a painless swelling, which causes facial asymmetry, where the radiological investigations reveals that there is unilocular or multilocular radiolucency, which is well or ill-defined with variable expansion along with destruction of cortical plate. Since the radiological appearance of this lesion is not pathognomonic, it is usually confused with the other lesions of the jaws. But the final diagnosis is based on its histopathology, though the clinical and radiological features are not specific.11 Histopathological features reveal that it is comprised of dense proliferation of oval or spindle shaped cells with varying number of multinucleated giant cells containing 20 nuclei. There is a deposition of hemosiderin, extravasted RBC’s, foci of osteoid material dystrophic calcification around the periphery of the lesion.12 Though multinucleated giant cells are in more in number, they cannot be considered as proliferative cells, since the macrophages, mesenchymal cells and fibroblasts are accountable for the growth of the lesion. Hence these cells release cytokines that stimulate the proliferation and recruitment of blood monocytes to become osteoclast like cells.13 The multinucleated giant cells may be large or small in number and they may be irregular or round cells that contains more than twenty nuclei which are responsible for bone resorption and local progression of lesion.14 The giant cells containing more nuclei and dese cellular stroma are found to be more aggressive and may relapse after surgical treatment.13 Some studies reveal a significant difference in the number of giant cells in aggressive and non-aggressive lesions where other studies reveal only few differences in the cell size in histomorphic analysis. Some of them found that the aggressive lesions show the higher number of giant cells with more irregular shape, where the giant cells are larger. There is a an increase in the mitotic activity along with a difference in histomorphic analysis which indicates increase in the fusion of resident macrophages and recruitment of monocytes and also there is higher metabolic activity of multinucleated giant cells that shows an aggressive clinical behavior.15 According to the differential diagnosis of the central giant cell granuloma , based on radiological investigation, being a small unilocular lesions it may be confused with granulomas and periapical cyst and the large multilocular lesions it may be ameloblastoma or lesions the resemble PGCL ,aneurysmal bone cyst, central odontogenic fibr oma, brown tumor of hyperthyroidism, giant cell tumor. The CGCG and brown tumor of hyperparathyroidism resembles each other histologically, in having an intense endogenous brownish pigmentation of hemosiderin. The additional test that help in diagnosis are serum calcium, phosphate, parathyroid hormone and alkaline phosphatase levels which are normal in CGCG, but increased in brown tumor of hyperparathyroidism. The CGCG usually occurs in both maxilla and mandible but the giant cell tumour more commonly occurs in the epiphyses of long bones. But both the lesions appear as osteolytic defects radiographically but can be differentiated histologically. Evidence reveals that the giant cells are larger, numerous and more round in giant cell tumor in CGCG, with a higher number of nuclei and eventually dispersed. There is fewer foci of osteoid material, areas of haemorrhage and there is deposition of hemosiderin and fibrosis and the stroma contains large and oval cells. The aneurysmal bone cyst can be differentiated from CGCG in having a network of multiple cystic cavities fill with blood within thin walls. Depending on the clinical and radiographic findings, if there is a well-defined lesion, curettage can be done where there is low recurrence, but if it is extensive lesion with perforated cortex, the radical excision is mandatory. Sometimes even partial maxillectomy or mandibulectomy and jaw reconstruction plates or placement of bone grafts can be done. Conclusion Based on the clinical, radiological, histopathological features, it is considered as an aggressive variant of CGCG, which is rare in occurrence. More clarification is needed regarding the pathogenesis and nature of giant cell lesions.

Moby Dick :: essays research papers

Moby Dick is an extremely long novel written by Herman Melville. This book is an epic tale of a crazed sea captain hunting the whale that bit off his leg told through the eyes of a school teacher. As the story begins Ishmael is at the local boating dock looking for work. Ishmael being a school teacher has allot of time off as of the moment because the school is at recess, for what reason i don't know. He is in a tavern talking amongst the whalers. He asks if they know of any ships on witch he could board as a hand for the captain. One of the stories he receives is of a man named Ahab. He is offering good pay and good work for any man who wants to join him on his ship. the only problem is that people say that he is a rather evil man. Ishmael shes one of the ships hands and boards for a trip witch he will never forget. The ship sets sail and every thing seems to be going smoothly. Everything except one tiny detail, Ishmael hasn't seen the captain Ahab. He knows hes there because he has heard men talking to him, but Ishmael has yet to see him. When Ishmael finally dose see captain Ahab he is shocked. The man is a very evil looking person. Ishmael can see the fire in his eyes. He is shocked by the pure hatred of witch Ishmael speaks of Moby Dick, the whale who took his leg. Because Ahab comes off as such an evil man Ishmael doesn't want to become any sort of a friend of him. He develops a slight dislikement of him and begins to call him Stubb when he isn't around. As the story goes on it describes in very good detail what happens on their whaling trip. I don't know if this is a normal whaling trip or not because i don't do much whaling myself. Ishmael describes in great detail all actions taking place on the ship that he sees. Until one day. One day as this ship is sailing along a whale is spotted. It isn't just any whale though, it is Moby Dick. Ahab becomes what seems to be almost possessed. He is so enraged with the whale that he orders everything to be stopped and every man is to concentrate on killing the whale. He has every man loaded in to the whaling boats and he begins his chase. He shouts at his men, and screams at the whale. He curses it as if it were from hell.
