In September 1964 Tyco opened up to the world and started its obtaining of different organizations to broaden its turn of events and appropriation arrange. Over the 22 years Tyco developed generously through key acquisitions and developing assorted variety inside the partnership. Some key acquisitions included: †¢1974: Simplex Technologies, makers of undersea fiber optic media communications link †¢1976: Grinnell Fire Protection Systems, makers of and temporary workers for fire sprinkler frameworks †¢1979: Armin Plastics, makers of polyethylene film items †¢1981: Ludlow Corporation, makers of bundling items.

The entirety of the achievements and development of Tyco can be contributed forceful administration by Roseburg and all administrators who emulated his example. Tyco is contained four specialty units: Electrical and Electronic Components, Healthcare and Specialty Products, Fire and Security Services, and Flow Control. The Companys name was changed from Tyco Laboratories, Inc. to Tyco International Ltd. in 1993, to reflect Tycos worldwide nearness. In 1997, after the merger with ADT, Tyco moved its joining from Massachusetts to Bermuda. In the course of the most recent two decades Tyco has seen a noteworthy ascent, blasting business, pulverizing outrage, and complete revival of the association. The company’s morals have been enduring an onslaught because of amazing lawful difficulties. Luckily, Tyco has been capable ricochet back, yet the street back wasn’t a simple one. Effective reaches There have been numerous impacts that formed and shaped Tyco since its beginning in 1960. On July 19, 2001, the U. S. Customer Product Safety Commission and Tyco Fire Products LP partner, Central Sprinkler Company, nnounced a deliberate substitution program. The review was in light of imperfect O-ring seals. Focal Sprinkler Company made a move when they found that the O-ring sprinklers were debasing after some time. As per their discoveries, the sprinkler heads could consume or contaminants, for example, salt could influence the O-ring seals. Those variables could have caused the sprinkler heads not enact in case of a fire. (CPSC, 2001) The work and free parts substitution secured 37 million fire sprinklers with O-ring seals produced using the mid-1970 until 2001. There were likewise 167,000 sprinkler heads additionally reviewed made by Gem Sprinkler Company and Star Sprinkler Inc. This move by Tyco the executives was provoked for two genuine reasons. The main purpose behind the review was the nature of the item that was discharged by Tyco. After broad research and testing, Central Sprinkler Company was blessed to get the deformity in its own item. The second and likely the most rousing component was the possibility of monstrous claims originating from a defective O-ring. Had the deficiency been ignored, numerous lives would have been placed at serious risk. The sprinkler review wasn’t the main review the Tyco International was confronted with; there was likewise review on smoke alarms. On May 19, 2006, Tyco Fire Security in collaboration with the Consumer Product Safety Commission discharged an item wellbeing review on Tyco Fire Security Fire Detection Systems. It was evaluated that the review influenced around 21,000 Fire Detection Systems all through the United States. The shortcoming fire recognition frameworks entirely vulnerable to diminished affectability to smoke in states of high mugginess and high temperature. If this somehow managed to happen, the senor on the gadget could have postponed distinguishing the nearness of smoke in case of a fire. Tyco Fire Security reached assembling proprietors and directors with these sensors and gave free programming overhauls. Like the review of the sprinkler O-rings, Tyco International administration had to address this possibly tragic issue. In addition to the fact that this is an issue of morals, yet additionally an issue of legitimateness. By being proactive in the issue, numerous lives were spared, the company’s notoriety was in respect, and no legitimate issues rose. In 1992, Dennis Kozlowski became CEO of Tyco International and led a forceful procurement procedure that prompted the obtaining large number of organizations. Throughout the decade Tyco International appreciated a consistent improve in profit and Kozlowski was continually positioned as one of most generously compensated CEO’s in the United States. In 2002, closely following discussions about separating the organization into four separate organizations, Tyco International experienced harsh criticism for unlawful bookkeeping rehearses. It was later found that there were a huge number of unapproved installments made to CEO Dennis Kozlowski and other Tyco workers. Dennis Kozlowski left the organization not long after the embarrassment, leaving investors and Tyco representatives uncertain of the company’s future. As indicated by reports, 11 names among the 51 Tyco representatives who, at Kozlowskis bearing and without board endorsement, got $56 million in rewards that as a result counterbalanced advances they had taken from the companys migration program. It was additionally discovered that $50 million was paid to Kozlowski and previous CFO Mark Swartz. The organization said Kozlowski abused $62 million of the companys coffers to buy a $16. million loft on Fifth Avenue in New York and $14 million for enhancements and goods to the condo. A portion of the goods that came up short on any real business reason incorporated a $15,000 hound umbrella stand; a $17,100 voyaging latrine box; a $6,000 shower drape; a $2,200 overlaid metal wastebasket; and $2,900 for coat holders. By and large, somewhere in the range of 1995 and 2002, Kozlowski just took care of $21. 7 million of the $62 million. (CBS, 2002) After selecting previous Motorola COO Edward Breen to CEO, Tyco International recorded two government claims against Kozlowski and an administrative suit against Swartz. Kozlowski and Swartz were accused of big business defilement and terrific robbery for supposedly taking $170 million from the organization and acquiring $430 million through the false deals of protections. Both were indicted for everything except one check. For this situation Tyco settled on right choice to indict anybody associated with this case. On the off chance that the embarrassment would have been inadequately dealt with, the monetary repercussions would have been pulverizing. In 2003, Tyco embraced the Guide to Ethical Conduct so as to control and encourage workers as to address systems and caution of exploitative practices and conduct. Every year Tyco workers are currently required to take a morals course and sign a morals articulation upon finishing. Not long after the aftermath of the embarrassment Tyco was confronted with claims from financial specialists. These speculators lost cash from protections they bought from Tyco between Dec 13, 1999 and June 7, 2002. Tyco had the option to settle with speculators for 2. 97 billion dollars. The Tyco settlement is right now the biggest ever by an organization (Norris, 2007). On June 29, 2007, Tyco separated into three free organizations, each with its own administration gathering. The three organizations are Covidien Ltd, Tyco Electronics Ltd, and Tyco International Ltd (in the past Tyco Fire Security and Tyco Engineered Products Services). Chief of Tyco International, Edward Breen and his administration staff have started chip away at restoring Tyco’s name and notoriety in the business network.

The matching hypothesis Essay Example

The coordinating speculation Paper There are numerous variables associated with the development of connections, vicinity, introduction and family, similitude, physical allure, integrally, skill and proportional loving. In this examination, the exploration will investigate allure, explicitly the match speculation. Zuckerman et al (1995) detailed that the more appealing an individual appeared to be, the more constructive was anothers in general impression of that individual. Symons (1979) demonstrated that a womans physical wellbeing, age, and uniqueness are appealing to men while a keeps an eye on status, stature, aptitudes, and capacities are alluring to ladies. Berry and Miller (2001) found that guys appraised physical appeal as the best indicator for better associations with lady, while lady evaluated amiability as the most significant factor for men. An investigation was done by Walster et al in 1966 known as the PC move study. 752 freshers partook. First they were advised to fill in a survey, after which they were informed that they had been apportioned a perfect accomplice for the night of the move. These pairings in any case, had been made indiscriminately on premise of their physical engaging quality. Understudies were asked the amount they enjoyed their date and on the off chance that they needed to see them once more. They found that physical appeal was the single greatest indicator of how much each date had been preferred by both male and the female members. The longing of another date was dictated by the engaging quality of the female, independent of the allure of the male. At the point when we see an individual in the road we consequently rate that people engaging quality, regardless of whether we do it deliberately or unwittingly.

It guarantees that individuals are bound to frame dependable associations with individuals who are generally similarly as genuinely appealing as themselves. This examination will imitate this investigation. The coordinating marvel of physical fascination between marriage accomplices is steady inside and across ages, Price and Vandenberg 1979. A few investigations have tried the coordinating speculation. These examinations by and large show that individuals evaluated as being of high, low or normal engaging quality will in general pick accomplices of a relating level of appeal. A few examinations have been completed that investigate this field of enthusiasm for, Murstein (1972) who likewise bolsters the coordinating speculation did an examination with photos of the essences of consistent or drew in couples were contrasted and arbitrary couples. The genuine couples were reliably decided to be increasingly like each other in levels of physical appeal than the irregular sets. Murstein summed up the discoveries of the investigation as: Individuals with equivalent market an incentive for physical appeal are bound to relate in a close connection, for example, commitment that people with dissimilar qualities. In straightforward terms, he found that individuals with generally equivalent appeal are bound to build up a close connection, than if one individual out of the couple was viewed as being ugly and the other alluring. This examination centers around couples separate allure and their engaging quality as a couple, breaking down solitary appeal and coupled engaging quality. The point of the examination is to explore the coordinating speculation and to test whether there is a positive connection between's the scores of apparent engaging quality of the male and female of the wedded couples and furthermore as a team.

Invalid theory: There would be no connection between's members saw scores of engaging quality of photos of wedded couples. Strategy The technique picked for this examination was a correlational research strategy, as a connection between the two factors was being explored. The co-difference is the male and female scores. All the photographs utilized all through the methodology are acquired from articles from a neighborhood paper. After the photographs are gotten, record sheets will be created on which the members will rate the couples. The photographs utilized will be kept together (I. e. they won't be cut into independent male and female segments) for the straightforward explanation that I am additionally posing the inquiry; do the couples coordinate one another? This would be difficult to do as such if the photos were isolated. This additionally makes my examination progressively unique. The members will at that point be given structures like the record sheet (reference section). Cause and examination was the proper strategy for this examination as it gives data on the quality of a connection between explicit factors.

While internal validity relates to how well a study is conducted (its structure), external validity relates to how applicable the findings are to the real world. Internal Validity Internal validity is the extent to which a study establishes a trustworthy cause-and-effect relationship between a treatment and an outcome.?? It also reflects that a given study makes it possible to eliminate alternative explanations for a finding. For example, if you implement a smoking cessation program with a group of individuals, how sure can you be that any improvement seen in the treatment group is due to the treatment that you administered? Internal validity depends largely on the procedures of a study and how rigorously it is performed. Internal validity is not a yes or no type of concept. Instead, we consider how confident we can be with the findings of a study, based on whether it avoids traps that may make the findings questionable. The less chance there is for confounding in a study, the higher the internal validity and the more confident we can be in the findings. Confounding refers to a situation in which other factors come into play that confuses the outcome of a study. For instance, a study might make us unsure as to whether we can trust that we have identified the above cause-and-effect scenario. In short, you can only be confident that your study is internally valid if you can rule out alternative explanations for your findings. As a brief summary, you can only assume cause-and-effect when you meet the following three criteria in your study: The cause preceded the effect in terms of time.The cause and effect vary together.There are no other likely explanations for this relationship that you have observed. Factors That Improve Internal Validity If you are looking to improve the internal validity of a study, you will want to consider aspects of your research design that will make it more likely that you can reject alternative hypotheses. There are many factors that can improve internal validity. Randomization refers to randomly assigning participants to treatment and control groups, and ensures that there is not any systematic bias between groups.Random selection of participants refers to choosing your participants at random or in a manner in which they are representative of the population that you wish to study.Blinding in a study refers to participantsâ€"and sometimes researchersâ€"being unaware of what intervention they are receiving (such as by using a placebo in a medication study) to avoid this knowledge biasing their perceptions and behaviors and thus the outcome of the study.Experimental manipulation refers to manipulating an independent variable in a study (for instance, giving smokers a cessation program) instead of just observing an association without conducting any intervention (examining the relationship between exercise and smoking behavior).Study protocol refers to following specific procedures for the administration of a treatment so as not to introduce any effects of, for example, doing things differently with one group of people versus another group of people. How Does Random Selection Work? Factors That Threaten Internal Validity Just as there are many ways to ensure that a study is internally valid, there is also a list of potential threats to internal validity that should be considered when planning a study.?? Confounding refers to a situation in which changes in an outcome variable can be thought to have resulted from some third variable that is related to the treatment that you administered.Historical events may influence the outcome of studies that occur over a period of time. Examples of these events might include a change in political leader or natural disaster that influences how study participants feel and act.Maturation refers to the impact of time as a variable in a study. If a study takes place over a period of time in which it is possible that participants naturally changed in some way (grew older, became tired), then it may be impossible to rule out whether effects seen in the study were simply due to the effect of time.Testing refers to the effect of repeatedly testing participants using the same measures. If you give someone the same test three times, isnt it likely that they will do better as they learn the test or become used to the testing process so that they answer diffe rently?Instrumentation refers to the impact of the actual testing instruments used in a study on how participants respond. While it may sound unusual, its possible to prime participants in a study in certain ways with the measures that you use, which causes them to react in a way that is different than they would have otherwise.Statistical regression refers to the natural effect of participants at extreme ends of a measure falling in a certain direction just due to the passage of time rather than the effect of an intervention.Attrition refers to participants dropping out or leaving a study, which means that the results are based on a biased sample of only the people who did not choose to leave (and possibly who all have something in common, such as higher motivation).Diffusion refers to the treatment in a study spreading from the treatment group to the control group through the groups interacting and talking with or observing one another. This can also lead to another issue called r esentful demoralization, in which a control group tries less hard because they feel resentful over the group that they are in.Experimenter bias refers to an experimenter behaving in a different way with different groups in a study, which leads to an impact on the results of this study (and is eliminated through blinding). External Validity External validity refers to how well the outcome of a study can be expected to apply to other settings. In other words, this type of validity refers to how generalizable the findings are. For instance, do the findings apply to other people, settings, situations, and time periods? Ecological validity, an aspect of external validity, refers to whether a studys findings can be generalized to the real world. While rigorous research methods can ensure internal validity, external validity, on the other hand, may be limited by these methods. Another term called transferability relates to external validity and refers to the qualitative research design. Transferability refers to whether results transfer to situations with similar characteristics. Factors that Improve External Validity What can you do to improve the external validity of your study? Inclusion and exclusion criteria should be used to ensure that you have clearly defined the population that you are studying in your research.Psychological realism refers to making sure that participants are experiencing the events of a study as a real event and can be achieved by telling them a cover story about the aim of the study. Otherwise, in some cases, participants might behave differently than they would in real life if they know what to expect or know what the aim of the study is.Replication refers to conducting the study again with different samples or in different settings to see if you get the same results. When many studies have been conducted, meta-analysis can also be used to determine if the effect of an independent variable is reliable (based on examining the findings of a large number of studies on one topic).Field experiments can also be used in which you conduct a study outside the laboratory in a natural setting.Reprocessing or calibration refers to using statis tical methods to adjust for problems related to external validity. For example, if a study had uneven groups for some characteristic (such as age), reweighting might be used. Factors That Threaten External Validity External validity is threatened when a study does not take into account the interactions of variables in the real world.?? Situational factors such as time of day, location, noise, researcher characteristics, and how many measures are used may affect the generalizability of findings.Pre- and post-test effects refer to the situation in which the pre- or post-test is in some way related to the effect seen in the study, such that the cause-and-effect relationship disappears without these added tests.Sample features refer to the situation in which some feature of the particular sample was responsible for the effect (or partially responsible), leading to limited generalizability of the findings.Selection bias refers to the problem of differences between groups in a study that may relate to the independent variable (once again, something like motivation or willingness to take part in the study, specific demographics of individuals being more likely to take part in an online survey).?? This can also be considered a threat to internal validity. Similarities and Differences Internal and external validity are like two sides of the same coin. You can have a study with good internal validity, but overall it could be irrelevant to the real world. On the other hand, you could conduct a field study that is highly relevant to the real world, but that doesnt have trustworthy results in terms of knowing what variables caused the outcomes that you see. Similarities What are the similarities between internal and external validity? They are both factors that should be considered when designing a study, and both have implications in terms of whether the results of a study have meaning. Both are not either/or concepts, and so you will always be deciding to what degree your study performs in terms of both types of validity. Each of these concepts is typically reported in a research article that is published in a scholarly journal. This is so that other researchers can evaluate the study and make decisions about whether the results are useful and valid. Differences The essential difference between internal and external validity is that internal validity refers to the structure of a study and its variables while external validity relates to how universal the results are.?? There are further differences between the two as well. Internal Validity Focus on accuracy and strong research methods Controls extraneous variables Conclusions are warranted Eliminates alternative explanations External Validity Results translate to world at large Findings are generalizable Outcomes apply to practical situations Results can be translated into another context Internal validity focuses on showing a difference that is due to the independent variable alone, whereas external validity results can be translated to the world at large. Examples An example of a study with good internal validity would be if a researcher hypothesizes that using a particular mindfulness app will reduce negative mood. To test this hypothesis, the researcher randomly assigns a sample of participants to one of two groups: those who will use the app over a defined period, and those who engage in a control task. The researcher ensures that there is no systematic bias in how participants are assigned to the groups, and also blinds his research assistants to the groups the students are in during experimentation. A strict study protocol is used that outlines the procedures of the study. Potential confounding variables are measured along with mood, such as the participants socioeconomic status, gender, age, among other factors. If participants drop out of the study, their characteristics are examined to make sure there is no systematic bias in terms of who stays in the study. An example of a study with good external validity would be in the above example, the researcher also ensured that the study had external validity by having participants use the app at home rather than in the laboratory. The researcher clearly defines the population of interest and choosing a representative sample, and he/she replicates the study for different technological devices. A Word From Verywell Setting up an experiment so that it has sound internal and external validity involves being mindful from the start about factors that can influence each aspect of your research. Its best to spend extra time designing a structurally sound study that has far-reaching implications rather than to quickly rush through the design phase only to discover problems later on. Only when both internal and external validity are high can strong conclusions be made about your results. An Overview of the Scientific Method

The Supernatural In Macbeth - 1858 Words

In the play Macbeth by WIlliam Shakespeare, the supernatural is an ever present force, seen in the witches, the ghost of banquo, and maybe some other places. The way Shakespeare portrays the supernatural, and especially the witches, add a great deal s to the play, and also contribute in key ways to the themes, structure, tone. Mood, and literary devices in ways that are designed to affect the audience of the play.

Does Macbeth kill the king because he was destined to, or because the witches made him think he was destined to? At the end, Macbeth was told he couldn’t be killed by a man born of a woman; was this ever true? Was he killed by Macduff because Macduff had been ripped from his mother s womb, or because Macbeth knew this and gave up? Really, Macduff only attacked Macbeth because Macbeth killed his family after being told he should fear him. The witches caused all of these things somehow, and whether they did it by supernaturally controlling fate or by manipulating Macbeth is one of the more interesting parts of the play to me. These themes (fair vs foul, and one s control over their own fat e) are important in adding a feeling of uncertainty, and creating some level of fear and suspense. The witches in Macbeth would have been especially scary and mysterious to the audience it was originally written for: the people living in England in the early 1600s, including the king himself.

An Analysis Of George Gershwin s An American Folk Opera

â€Å"An American Folk Opera.† George Gershwin’s most successful piece of expansive musical drama was subtitled with this term that no musician or critic had applied to a work of musical drama before the 1935 premiere of Porgy and Bess. Much has been written about the work’s subtitle; its literal meaning, its evolution, and its implications for a changing cultural landscape. Porgy and Bess was the last in a triptych of literature and theater surrounding the character of Porgy, a crippled beggar living in Charleston’s semi-fictitious Catfish Row.

All else dies.† Similar to Dvorak in his ninth symphony, the idiom that Gershwin employed for his opera was that of the Negro spiritual and folk song. Before composing Porgy and Bess, Gershwin made a trek down to Charleston, South Carolina and some of its outlying island communities with the purpose of studying â€Å"rural African American† culture. It was there that he became immersed in the music of that community and it was there that he garnered his inspiration for the opera’s score. Again harkening to the traditions of the European masters, Gershwin decided against the note-for-note transcription of the songs he had heard, but rather used them as inspiration for a continuous musical narrative of folk-inspired themes.

The ground became increasingly waterlogged, and there was widespread, localised flooding from surface water run-off. Uckfield flooded dramatically from about 5.00am on the 12th October, with river levels rising rapidly to a peak between 9.00am and 10.00am, at which point a torrent of water up to 1.9m deep, was flowing through the town centre causing considerable damage. Barcombe and Lewes filled up and widespread flooding in Lewes started at about 1.00pm, as the rising river backed up behind the Cliffe Bridge and overtopped the flood defences at a number of locations. Within about an hour or so the flood defences throughout the town were completely overwhelmed and the town centre rapidly filled with floodwater. Many hundreds of people were stranded and had to be rescued by the Emergency Services in boats. By the time the floodwaters peaked at about 9.30pm, some parts of Lewes were less than 3.6m of water. As the flows passing downstream from Barcombe continued to increase at a rapid rate, the floodwaters weired over the river walls and surged through the streets and open areas in Lewes, rapidly filling up sections of the urban floodplain to a depth of 1m in about half an hour. The Police abandoned the centre of town, and the evacuation turned into a rescue operation as the RNLI and Emergency Services used inflatable lifeboats to reach people suddenly trapped in their homes or businesses. The flood devastated the centres of Uckfield and Lewes, as well as causing significant damage to surrounding rural properties and the farming community. * long periods of drying out and repair mean that many homes have remained uninhabitable for many months after the event, with residents having to live in alternative, temporary accommodation; * similarly, many businesses remain closed months after the flood, and a small number are believed to have closed permanently; * a long term loss of trade, both for the flooded businesses, and for the wider business community; * widespread concerns about property values and insurance; * losses of agricultural crops and livestock; * impact on County Council Social Services provision due to the loss of day centres and buses; * long term damage to road surfaces, and widespread blockage of highways drainage systems; * impact on Lewes District Council’s housing provision due to temporary re-accommodation of flood victims; * disruption to the Fire Brigade and Ambulance Service due to the temporary loss of several of their buildings, including their control centres, and loss of vehicles; * in Lewes, 118 Listed Buildings and 230 other ‘traditional’ buildings within the Conservation Area were damaged, requiring specialist repair; * long term needs for emotional support amongst some. This means that the upper and middle sections of the catchments become quickly saturated following heavy rainfall. During wet periods a large proportion of the rainfall will quickly run-off into the river system rather than drain through the ground, and this effect is exacerbated by the hilly nature of the upper parts of the catchment. * increasing the amount and rate of surface water run-off, thereby increasing flows; * reducing the area available for flood storage, thereby increasing peak levels; * reducing the area available for flood flow conveyance, thereby increasing peak levels, contributing to rapid inundation and high flood velocities, and extending the period of flooding. * River flows were increasing very rapidly at this time and continued to do so for several hours after the flood defences were overtopped. * The upstream flood storage areas were already ‘full’ so that the majority of the flood flows passed straight downstream to Lewes with little attenuation. * Once overtopped, the flood defences acted like weirs allowing large volumes of water to pass over them in a short space of time, rapidly filling the low lying areas behind them, with high velocities being witnessed where flows were channelled through narrow gaps. * The natural narrowing flood plain as it approaches Lewes, together with the artificial obstructions across its path in Lewes (Phoenix Causeway, Mayhew Way, Cliffe High Street shops) severely reduces the ability of the flood plain through Lewes to convey flood waters, causing levels to rise higher still. *  It is an obvious point, but maybe worth stating, that the 12th October 2000 flood inundated the floodplain – so named for a good reason. The devastating impact of the flood was because large numbers of properties have over the years been built on the floodplain, and although artificial flood defences or river improvement works have protected those properties from more frequent flooding events, all property constructed on the flood plain is at risk of flooding occasionally. The Environment Agency’s Flood Warning slogan of â€Å"You cannot prevent flooding, you can only prepare for it†. The existing flood defences were overwhelmed by the 12th October 2000 flood flows and it may be possible to justify future improvements to raise the current standards of defence to protect against an event of similar magnitude. A number of options are likely to be considered in the forthcoming Catchment Strategy Plan being commissioned by the Environment Agency. However, given the extreme severity of 12th October 2000 event, and the nature of the long-standing government rules and arrangements for project appraisal and flood defence funding, we do not believe that it is reasonable to assume that they should already have been of such a standard. Nevertheless we believe that there are a number of important issues relating to the existing flood defences in Lewes which need to be urgently addressed, in particular the apparently poor condition of many of the river walls through the town, and the long term settlement in the upstream flood embankments. The floodwalls were breached or damaged in at least 8 locations through the town, and the sudden failure of the river wall at Phoenix Industrial Estate is particularly worrying. The flooding took many residents by surprise, and it is clear that the Environment Agency and a significant number of affected residents have very different perceptions about the performance of the flood warning system. This is partly an issue of communication and education. We believe that it is important that the Environment Agency vigorously continues its efforts to educate local residents, and that it is explicit about its actual responsibilities and capabilities. With the benefit of hindsight, we also believe that a number of important improvements in the flood warning and forecasting service can be identified, and should be undertaken. These would not have had any impact on the extent, speed or depth of the actual flooding, but they may have meant that for many, vehicles, stock, or precious personal possessions might have been saved.

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.​​ 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 Paulo’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 Paulo’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 Napoleon’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 ones’ 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 â€Å"Us too advocacy† 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 â€Å"Zero prostate cancer†

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 world’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  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 – 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 – 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 – 2 10 | Yoga for Eye Sight Improvement camera. Our eye although is comparable to a camera, is not having a shape of a camera.

What Is an Oxidant Definition of Chemistry Terms

An oxidant is a reactant that oxidizes or removes electrons from other reactants during a redox reaction. An oxidant may also be called an oxidizer or  oxidizing agent. When the oxidant includes oxygen, it may be called an oxygenation reagent or oxygen-atom transfer (OT) agent. How Oxidants Work An oxidant is a chemical species that removes one or more electrons from another reactant in a chemical reaction. In this context, any oxidizing agent in a redox reaction may be considered an oxidant. Here, the oxidant is the electron receptor, while the reducing agent is the electron donor. Some oxidants transfer electronegative atoms to a substrate. Usually, the electronegative atom is oxygen, but it can be another electronegative element or ion. Oxidant Examples While an oxidant technically doesnt require oxygen to remove electrons, most common oxidizers do contain the element. The halogens are an example of oxidants that dont contain oxygen. Oxidants participate in combustion, organic redox reactions, and more explosives. Examples of oxidants include: hydrogen peroxideozonenitric acidsulfuric acidoxygensodium perboratenitrous oxidepotassium nitratesodium bismuthatehypochlorite and household bleachhalogens such as Cl2 and F2 Oxidants As Dangerous Substances An oxidizing agent that can cause or aid combustion is considered a dangerous material. Not every oxidant is hazardous in this manner. For example, potassium dichromate is an oxidant, yet is not considered a dangerous substance in terms of transport. Oxidizing chemicals which are deemed hazardous are marked with a specific hazard symbol. The symbol features a ball and flames. Sources Connelly, N.G.; Geiger, W.E. (1996).

5 Most Important Things You Can Do for the Environment

If you feel you’re not doing enough for the environment by replacing your incandescent light bulbs with LED lights and composting your kitchen scraps, maybe you’re ready to make a deeper commitment to environmental stewardship. Some of these strategies may seem a little radical, but they are among the most valuable actions you can take to protect and preserve Earth’s environment. Have Fewer Children—Or None Overpopulation is arguably the world’s most serious environmental problem because it exacerbates all of the others. The global population grew from 3 billion in 1959 to 6 billion in 1999, an increase of 100 percent in just 40 years. According to current projections, the world population will expand to 9 billion by 2040. This represents a slower growth rate than that of the last half of the 20th century, but it will nevertheless leave us with many more people to accommodate. Planet Earth is a closed system with limited resources—only so much fresh water and clean air and only so many acres of land for growing food. As the world population grows, our finite resources must stretch to serve more and more people. At some point, that will no longer be possible. Some scientists believe we have already passed that point. Ultimately, we need to reverse this growth trend by gradually bringing the human population of our planet back down to a more manageable size. This means more people must decide to have fewer children. This may sound pretty simple on the surface, but the drive to reproduce is fundamental in all species. The decision to limit or forgo the experience is a difficult one for many people because of emotional, cultural, and religious traditions and pressures. In many developing countries, large families can be a matter of survival. Parents often have as many children as possible to ensure that some will live to help with farming or other work and to care for the parents when they are old. For people in cultures like these, lower birth rates will only come after other serious issues such as poverty, hunger, poor sanitation, and freedom from disease have been adequately addressed. In addition to keeping your own family small, consider supporting programs that fight hunger and poverty, improve sanitation and hygiene, or promote education, family planning, and reproductive health in developing nations. Use Less Water—And Keep It Clean Fresh, clean water is essential to life—no one can live long without it—yet it is one of the scarcest and most endangered resources in our increasingly fragile biosphere. Water covers more than 70 percent of the Earth’s surface, but most of that is salt water. Freshwater supplies are much more limited and today a third of the world’s people lack access to clean drinking water. According to the United Nations, 95 percent of the cities worldwide still dump raw sewage into their water supplies. Not surprisingly, 80 percent of all illnesses in developing countries can be linked to unsanitary water. Especially if you live in a dry climate, you should use only as much water as you need, avoid wasting the water used, and strive to protect  water supplies. Eat Responsibly Eating locally grown food supports local farmers and merchants in your own community as well as reducing the amount of fuel, air pollution, and greenhouse gas emissions required to move the food you eat from the farm to your table. Eating organic meat and produce keeps pesticides and chemical fertilizers off your plate and out of rivers and streams. Eating responsibly also means eating less meat and fewer animal products such as eggs and dairy products, or perhaps none at all. Eating less meat is a matter of good stewardship of our finite resources. Farm animals emit methane, a potent greenhouse gas that contributes to global warming, and raising animals for food requires many times more land and water than growing food crops. Livestock now uses 30 percent of the planet’s land surface, including 33 percent of farmland worldwide, which is used to produce animal feed. Every time you sit down to a plant-based meal instead of an animal-based meal, you save about 280 gallons of water and protect anywhere from 12 to 50 square feet of land from deforestation, overgrazing, and pesticide and fertilizer pollution. Conserve Energy—And Switch to Renewable Energy Walk, bike, and use public transportation more. Drive less. Not only will you be healthier and help to preserve precious energy resources, but you’ll also save money. According to a study by the American Public Transportation Association, families that use public transportation can reduce their household expenses by $6,200 annually, more than the average U.S. household spends on food every year. There are dozens of other ways you can conserve energy. You can turn off lights and unplug appliances when they are not in use and substitute cold water for hot whenever practical. Other small steps you can take include weather stripping your doors and windows and not overheating or overcooling your home and office. (An added bonus is that a good office temperature also boosts productivity.) One way to start is to get a free energy audit from your local utility. Whenever possible, choose renewable energy over fossil fuels. For example, many municipal utilities now offer green energy alternatives so that you can get some or all of your electricity from wind, solar, or other renewable energy sources. Reduce Your Carbon Footprint Many human activities—from using coal-fired power plants to generate electricity to driving gasoline-powered vehicles—cause greenhouse gas emissions that heat the atmosphere and contribute to climate change. Scientists are already seeing significant climate changes that point to the likelihood of serious consequences. Some scenarios foresee increasing drought that could further reduce food and water supplies and, at the same time, rising sea levels that will submerge islands and coastal regions and create millions of environmental refugees. Online calculators can help you measure and reduce your personal carbon footprint, but climate change is a global problem that requires global solutions and, so far, the world’s nations have been slow to find common ground on this issue. In addition to lowering your own carbon footprint, let your government officials know that you expect them to take action on this issue—and keep the pressure on until they do.
