The History of Sao Paulo
The History of Sao Paulo So Paulo, Brazil is the largest city in Latin America, edging out runner-up Mexico City by a couple of million inhabitants. It has a long and interesting history, including serving as home base for the infamous Bandeirantes. Foundation The first European settler in the area was Joo Ramalho, a Portuguese sailor who had been shipwrecked. He was the first to explore the area of present-day So Paulo. Like many cities in Brazil, So Paulo was founded by Jesuit Missionaries. So Paulo dos Campos de Piratininga was established in 1554 as a mission to convert Guains natives to Catholicism. In 1556-1557 the Jesuits built the first school in the region. The town was strategically located, being between the ocean and fertile lands to the west, and it is also on the Tietà ª River. It became an official city in 1711. Bandeirantes In the early years of So Paulo, it became the home base for the Bandeirantes, which were explorers, slavers, and prospectors who explored the interior of Brazil. In this remote corner of the Portuguese Empire, there was no law, so ruthless men would explore the uncharted swamps, mountains and rivers of Brazil taking whatever they wanted, be it native slaves, precious metals or stones. Some of the more ruthless Bandeirantes, such as Antonio Rapà ´so Tavares (1598-1658), would even sack and burn Jesuit missions and enslave the natives who lived there. The Bandeirantes explored a great deal of the Brazilian interior, but at a high cost: thousands, if not millions of natives, were killed and enslaved in their raids.ââ¬â¹Ã¢â¬â¹ Gold and Sugar Gold was discovered in the state of Minas Gerais at the end of the seventeenth century, and subsequent explorations discovered precious stones there as well. The gold boom was felt in So Paulo, which was a gateway to Minas Gerais. Some of the profits were invested in sugarcane plantations, which were quite profitable for a time. Coffee and Immigration Coffee was introduced to Brazil in 1727 and has been a crucial part of the Brazilian economy ever since. So Paulo was one of the first cities to benefit from the coffee boom, becoming a center for coffee commerce in the nineteenth century. The coffee boom attracted So Pauloââ¬â¢s first major wave of foreign immigrants after 1860, mostly poor Europeans (particularly Italians, Germans, and Greeks) seeking work, although they were soon followed by a number of Japanese, Arabs, Chinese, and Koreans. When slavery was outlawed in 1888, the need for workers only grew. So Pauloââ¬â¢s considerable Jewish community also was established around this time. By the time the coffee boom fizzled in the early 1900s, the city had already branched out into other industries. Independence So Paulo was important in the Brazilian independence movement. The Portuguese Royal Family had moved to Brazil in 1807, fleeing Napoleonââ¬â¢s armies, establishing a royal court from which they ruled Portugal (at least theoretically: in reality, Portugal was ruled by Napoleon) as well as Brazil and other Portuguese holdings. The Royal family moved back to Portugal in 1821 after the defeat of Napoleon, leaving eldest son Pedro in charge of Brazil. The Brazilians were soon angered by their return to colony status, and Pedro agreed with them. On September 7, 1822, in So Paulo, he declared Brazil independent and himself Emperor. Turn of the Century Between the coffee boom and wealth coming from mines in the interior of the country, So Paulo soon became the richest city and province in the nation. Railroads were built, connecting it to the other important cities. By the turn of the century, important industries were making their base in So Paulo, and the immigrants kept pouring in. By then, So Paulo was attracting immigrants not only from Europe and Asia but from within Brazil as well: poor, uneducated workers from the Brazilian northeast flooded into So Paulo looking for work. The 1950s So Paulo benefited greatly from the industrialization initiatives developed during the administration of Juscelino Kubitschek (1956-1961). During his time, the automotive industry grew, and it was centered in So Paulo. One of the workers in the factories in the 1960s and 1970s was none other than Luiz Incio Lula da Silva, who would go on to become president. So Paulo continued to grow, both in terms of population and influence. So Paulo also became the most important city for business and commerce in Brazil. So Paulo Today So Paulo has matured into a culturally diverse city, powerful economically and politically. It continues to be the most important city in Brazil for business and industry and lately has been discovering itself culturally and artistically as well. It has always been on the cutting edge of art and literature and continues to be home to many artists and writers. It is an important city for music as well, as many popular musicians are from there. The people of So Paulo are proud of their multicultural roots: the immigrants who populated the city and worked in its factories are gone, but their descendants have kept their traditions and So Paulo is a very diverse city.

Developing a Health Advocacy Campaign , Prostate Cancer Research Paper
Developing a Health Advocacy Campaign , Prostate Cancer Funding - Senator Boxer introduced the Prostate and Mens Education Act, - Research Paper Example The cause of prostate cancer is not clearly understood, but researchers argue that issues like race, family and age are beyond onesââ¬â¢ control. But some risk factors like avoiding fatty foods can be avoided as one is advised to eat more fruits, unsaturated foods, whole grains and intake of less red meat. Some medication from well equipped health centers helps reduce the spread of the cancer in the body. Drugs like; finastede have shown to reduce the prostrate cancer risk (John, 2008). California population is the most affected with cancer cases with 1,277,200 people affected with different types of cancer. The state projects that in 2012, more than 144,800 new cases will occur. The patients with prostate cancer include 20,195 new cases that makes up to 28% and 3,085 deaths occurs. The survivors of prostate cancer are 240,200 that accounts for 42%. Although from 1988 to 2009, 11% reduction has been reported as mortality reduces by 23% (CCR, 2012). The advocacy that have been effective include the ââ¬Å"Us too advocacyâ⬠that uses the prostate cancer survivors and victims to spread the awareness creation. They give speeches in forums, hold door to door awareness creations and attended screening centers to help explain to the attendees the screening environment. The attributes that makes this advocacy campaign is that it involves survivors, volunteers and experts to spread the required awareness messages. The volunteers take their time to deliver the message of the benefits of early screening, explaining the screening environment to the people so that they attend the screening exercise and encouraging people the people to attend the screening centers. The other attribute makes this advocacy to be effective is the involvement of medical experts on comprehensive research and provision of a variety of advanced treatment (CCR, 2012). The other advocacy campaign that is effective is the ââ¬Å"Zero prostate cancerââ¬

Strategy and change management Essay Example | Topics and Well Written Essays - 3000 words
Strategy and change management - Essay Example Therefore, several leading airlines have decided to merge with each other in order to reduce several business threats. Delta Airlines, Inc. and Northwest Airline Corp. in 2008 have proclaimed that they are going to merge with each other in order to create worldââ¬â¢s largest airline named Delta. . Due to merger, the flexibility to acclimatize to the economic challenges of Delta has increased. After the merger, Northwest Airline is the completely owned subsidiary of Delta. According to the market characteristic theory of low-cost airlines, it is feasible that low-cost airlines usually compete in such a market where the traveller density is high enough to develop the competitive advantages by offering rapid-return and time to time services. Lower fares usually results from the economies of traffic density. This type of economies of scale is one of the key features in the airline network model. Such strategic actions also bring certain non-price benefits also. Current trends towards the product differentiation seem to be one of the elements of competition. Due to such strategic actions the airline companies have increased incentive to correspond and improve customer service quality. Due to the economic down turn the company along with the whole airlines companies in Europe and America went through a tough phase. The competition has been intense regarding fares, services and routes. Also the company indulged in to a legal battle with the union airlines. A problem faced by the company has been the over dependence on the North-American market Merger and acquisition in airline industry is one of the interesting topics within the industry. The airline industry has experienced high disorder due to high operational cost and increasing price of petrol (Hackbarth and Miao, 2007, p.33). The study will reveal the effect of merger on the business performance of two leading airlines

Cause And Treatments Of Typhoid Fever Infections Biology Essay
Cause And Treatments Of Typhoid Fever Infections Biology Essay The burden and rigourness of typhoid fever infections caused by Salmonella enterica serovar Typhi is a substantial universal populace concern, particularly in developing countries (Demczuk, Finley, Nadon, Spencer, Gilmour NG, 2010). It is a systemic infection primarily involving the alimentary tract (Christopher, 2002). It has been found that humans are the only natural reservoirs of S. Typhi, with contagion occurring through consumption of faecally contaminated food and water (Corner Schwartz, 2005) or in other words, it occurs where there is substandard water supply and sanitation. It has been estimated by WHO that the annual global incidence of typhoid fever is at 0.3% (Demczuk et.,al, 2010). It has been estimated that annually 6, 00,000 deaths occur from enteric fever worldwide. S. Typhi infections may cause symptoms like bacteraemia, fever, headache, malaise, abdominal distress, diarrhoea and rose colored spots which contains the infecting organism (Chamberlain, 2006). Typhoid fever is preventable through vaccination prior to travelling to areas where typhoid is common and careful consumption of food. Treatment with appropriate antibiotics can also prevent complications. S.typhi first of all invades the alimentary canal by ingestion then via the lymphatic system and the thoracic duct into the stream of blood. This first septicaemic phase leads to infection of the reticulo-endothelial system and the gall bladder. When the infection of the gall bladder occurs, there is discharge of organisms into the intestine, with heavy infection of the Peyers patches and septicaemia- and the onset of symptoms (Sleigh Timbury, 1998). Most of the symptoms which are caused by S.typhi can be ascribed to the inflammation caused by its lipopolysaccharide as it does not have any specific known endotoxins. After an incubation period of 10-14 days, early symptoms like fever, headache and respiratory symptoms appear. Then, mild abdominal pain with either diarrhoea or constipation occurs. After that, fever increases in a stepwise fashion. Without treatment, the patient may eventually lapse into a stupor and the problem may persist for 4 to 6 weeks. A serious problem that is secondary invasion of the intestine from the gall bladder which can cause perforation of the intestine. In 15% of untreated cases, death may also occur. Typhoid fever can be diagnosed by the laboratory tests to find the bacteria in the blood or faeces of an infected person. Illness is usually characterized by fever, loss of appetite, lethargy and change in bowel habit. Constipation is common in the initial stages but diarrhea can also occur. The diagnosis of enteric fever relies on the isolation of S.typhi from the patient. Specimens include faeces, blood and urine. The culture used for blood and urine is MacConkey medium in which enrichment and the selective media are not necessary. Blood culture is positive in more than 80% of patients in the first week of illness. Faeces should also be cultured especially at 2-4 weeks after onset of symptoms, when seeding of the kidneys and secondary infection of the intestine occurs. For faeces, indicator medium is used for non-lactose-fermenting colonies and selective and enrichment media for others (Sleigh Timbury, 1998). Identification can be done by the Biochemical reactions (API test). In this test, unlike other salmonellae, S.typhi produces no gas on fermentation of sugars. In serological identification, first of all preliminary diagnosis with salmonella polyvalent H and O antisera is done and after that final identification is done from where it is send to the Reference Typing Laboratory. Phage typing is also useful in identifying the different types of S.typhi for epidemiological identification into the source of outbreaks. Serum antibodies to the organisms can be detected by an agglutination test known as Widal test, but positive results must be interpreted with care where past exposure or vaccination are possibility. A fourfold rise in titre between acute and covalescent sera is diagnostic. The salmonella bacterium resides in the human gut. The source of infection is the carriers or the cases that excrete the organism: excretion in faeces and less commonly in the urine. The infection continues for about two months after the acute illness. The route of infection is through the ingestion of water or food which is contaminated by sewage or via the hands of a carrier. Direct spread from case to case is rare. Only a small number of these bacteria can cause typhoid fever. This is the main reason that water-borne infection is common, despite the dilution of organisms. The following are High risk groups for developing Typhoid Fever: Travelers with individualistic lifestyle and those are intending prolonged travel to areas where there is typhoid fever. Former migrants from developing countries who are visiting their parent countries. Those with no acid or low acid concentrations in their stomach such as post surgery or with regular use of antacids and medication to reduce stomach acidity. Those with sever or ongoing disease may need particular advice about typhoid fever and where the intended travel is to be Travelers to the Indian Subcontinent Medical personnel, foreign aid workers and military personnel assigned in developing countries. Outbreaks of typhoid fever are often explosive- sometimes involving large number of people. There are two main types of outbreak: Water-borne: in which the organisms from the sewage acts as a carrier and pollutes the drinking water, e.g. the outbreaks in Croydon in 1937 and in Zermatt in 1963. Food- borne: in which food becomes contaminated via polluted water or via the hands of the carriers. Typhoid Mary, possibly most famous carrier, worked as a cook in USA and caused number of outbreaks. Tinned food may also become contagious during canning- the large outbreak in Aberdeen in 1964 was due to a tin containing corned beef which had been cooled in water contaminated by sewage; bacteria entered the can through tiny holes in the metal casing. Shellfish often grow in estuaries, where the water may be contaminated by sewage: if it is eaten uncooked they may cause infection. Milk or cream products, contaminated through the handling of the carriers, have caused outbreaks of typhoid fever. Other food products like meat, dried and frozen foods, dried coconut have also been responsible for infection. Antibiotics are a type of medication effective in treating infections caused by bacteria based on signs and symptoms. Oral treatment with chloramphenicol, ampicillin, cotrimoxazole or ciprofloxacin is generally effective and should be maintained for 14 days to reduce the possibility. But resistive strains to above antibiotics have also been reported, particularly on Indian subcontinent (Lee Bishop, 2010). For chronic carriers, long term therapy with ampicillin or ciprofloxacin may be effective but, if not, cholecystectomy (removal of gall bladder) may be warranted. Chloramphenicol is a bacteriostatic antibiotic with wide spectrum of activity against gram-positive and gram negative cocci and bacillus. It binds to the 50S subunit of the ribosome and inhibits bacterial protein synthesis. Ampicillin is a broad spectrum semi-synthetic derivative of aminopenicillin that inhibits bacterial cell wall synthesis by binding to penicillin binding proteins and inhibiting peptidoglycan synthesis, a critical component of bacterial cell wall. Ciprofloxacin is a synthetic broad spectrum fluoroquinolone antibiotic which inhibits bacterial DNA gyrase, an enzyme essential for DNA replication. This agent is more active against Gram-negative bacteria than Gram-positive bacteria. It is very difficult to eradicate S.typhii from the gall bladder. Antibiotic treatment is effective in curing some carriers, but still to some extent the infection persists and they become long-term permanent carriers. Promising results have been given by ciprofloxacin. For the high risk groups, two effective typhoid vaccines: the oral live vaccine (Ty 21a) and the injectable Vi capsular polysaccharide vaccine is highly recommended. The live attenuated vaccine Ty 21a is a strain of S.typhi. It is indicated for those who travel to or living in areas where typhoid is an endemic and where the health care staff is at risk. It is administered in enteric-coated capsules orally in three doses on alternate days. Some mild adverse reactions may also persist like nausea, vomiting etc. This vaccine is quiet efficient but may be less durable. The other type of vaccine is a classic type killed vaccine which has now been replaced by other preparations but still it is being widely used. It contains heat killed phenol preserved suspension of S.typhi. It is injected and two doses need to be consumed 4-6 weeks apart and booster doses need to be taken every 3 years. In consuming this, some local and general reactions are common which vanishes after 36 hr from the onse t. In New Zealand, the injectable Vi Polysaccharide vaccine (Vi antigen) is recommended for all adult children over the age of 2 years travelling to areas where there is questionable sanitation. It is known that children under the age of 2 years may show a sub-optimal response to polysaccharide antigen vaccine. It gives approximately 70% protection against the disease. There are two products available in New Zealand and Australia: Typherix (GlaxoSmithKline) and Typhim Vi (MSD [NZ] Ltd). They are interchangeable. The infection prevention and control team plays a vital role in preventing cross infection and prevention of hospital acquired infection. In order to ensure that infection is not caused, the surveillance team should keep highest level of vigilance in which phenomenon like proper aseptic techniques, hand hygiene practice should be followed. Furthermore, following preventive measures should be followed: Wash and dry hands thoroughly after using the toilet or changing nappies. Hands should be washed for 20 seconds and dried for a further 20 seconds using a clean cloth or disposable towel. Soiled clothing and linen should be washed with hot soapy water separately from that of other family members. Items such as face cloths and towels should be kept for personal use. A person with Typhoid infection should avoid preparing food for others in the family until they are no longer infectious. In households where a person is recovering from typhoid, toilet seats, flush handles, wash basin taps and toilet door handles should be disinfected daily using a hypochlorite based solution. Ideally the solution should be in contact with the surface of the object for at least à ½ hour. Drink bottled, purified or carbonated water for drinking and cleaning teeth. Make sure that bought bottled water is appropriately sealed; regular water (sea level) should be brought to boiling point for one minute before it is safe to drink. Avoid ice in drinks and remember that refreshing ice blocks and flavored ices may be made with contaminated water. Foods should be thoroughly cooked and served piping hot. Be very wary of food sold by street vendors. Avoid raw seafood and shellfish; even though they may have been preserved with vinegar, lemon or lime juice. Choose raw vegetables and fruits that a person can peel himself. Avoid salads unless they have been made by own. Do not forget to wash hands with soap or hand cleaner first and not to eat the peelings. Antimicrobial resistance surveillance is also a significant activity which needs to be practiced. Moreover, as the economies of the developing countries grow the sanitary conditions of currently typhoid- endemic countries will improve. Due to that, number o f typhoid fever cases will lessen. However, in order to expedite the elimination of typhoid fever, Member States and WHO will strengthen their power for typhoid fever surveillance by improving laboratory-based surveillance. Intersectoral collaboration at both national and international levels will be essential if the disease needs to be controlled in endemic countries. In conclusion we have discussed in brief the organism- S.typhi, the laboratory diagnosis, its epidemiology, antibiotic treatment and finally the role of the infection control and prevention team in controlling the infection.

Yoga for Eye Sight
The great master Swami Vivekananda said that there are four main streams of yoga:Jnana Yoga, Raja Yoga, Bhakti Yoga and Karma Yoga. To use all these streams of yoga to build the personality. We are now going to focus on Eyesight Development or Eyesight Improvement. In late 60s the TV came afresh in Bangalore city and everybody was so fascinated, particularly the children glued themselves to TV forgetting all their sports outside. Went on watching 3 hours, 4 hours, 5 hours, 6 hours and movies after movies and as expected it started happening in 5 or 6 years, 1972-73 we started seeing most of these children wearing very thick glasses.We felt too bad. We said can we solve this problem? Many people said that we are not going to allow our children to watch the TV. That is no solution. This is when we started developing yoga module. The specialised techniques that yoga prescribes for eyesight improvement were selected from various yoga techniques. The precautions we have to take, norms tha t we have to follow were taken care. So we developed this module, iintegrated yoga module for eyesight improvement. We started giving that in Yoga Camps.One week camp, 15 days camp, one month camp and we started documenting the result whether really it is useful or not. The results were very fascinating. When we have an average of 1000 or 1500 sstudents, we have found that the eyesight can improve by one Diapter for short sight sstudents with a practice of every day half an hour for one month. This iintegrated yoga module can bring such wonderful results. Practice for half an hour every day for one month, one Diaptor is going to reduce. Yoga in Education for Total Personality Development SERIES ââ¬â 2 8 | Yoga for Eye Sight ImprovementWhen we continued children with -5, -6, -7 children were able to normalise their eyesight. Then we started taking up this. Initially we have short theory and then we go for the practice and what is the whole basis for the eyesight improvement that we are talking? Many people think that the accommodation power of the lens is going to change. No. It is Eye Ball Curvature. In short sight the image is falling too far in front of the Fovea. But why is that distortion taking place in the eye ball? This is because of the differential pull of the rectie muscles of the eye ball.So when we do yoga in which we handle the eye excercises to see that the muscles co-ordinate so cohesively that the eye ball starts becoming normal. How do we know it is going to become normal? One of our Opthalimic specialist Dr. Upadhyay in England, measured the eye ball curvature and after 15 days, after one month of yogic practices the eye ball curvature started getting normal. Such results prove that yoga brings in normalisation and it is these techniques that we have used. Trataka is the specialised practice that yoga prescribes. It is one of the six kriyas.Kriyas are essentially meant for clearnsing and to strengthen the nerves which connect the eyes to the brain which handles the different muscles and calming down of the mind, silencing of the mind, slowing down of the breath, does wonders. Therefore in this module we are going to use some Asanas, special breathing practices and mainly the Trataka and the meditation which help the people develop their eyesight. Yoga in Education for Total Personality Development SERIES ââ¬â 2 Yoga for Eye Sight ImprovementLet us try to understand the structure and functions of the eye so that we can go ahead to understand how Yoga works in improving our eyesight. We all have two eyes. A resting eye is designed for distant vision. Near work always involve lot of work on the small, little muscles of the eye. Each eye is comparable to a pholographic camera. Just like the camera has a diaphragm and an aperture, our eye also has a dark highly pigmented diaphragm called Iris. This Iris cuts off all the light from entering into the eye ball and in the centre of the diaphragm is the little transparen' t hole called the Pupil.The diaphragm is called the Iris, the apercher is called the pupil. Through this pupil only nature allows the light to pass through. What are the functions of a good camera? It should have a very good powerful lens so that it can have a very clear image at its focal point and it should be able to adjust very perfectly to the light conditions and also to the distance of the object from the film of the Yoga in Education for Total Personality Development SERIES ââ¬â 2 10 | Yoga for Eye Sight Improvement camera. Our eye although is comparable to a camera, is not having a shape of a camera.
