Water and Sustainability Term Paper Example | Topics and Well Written Essays - 1750 words
Water and Sustainability - Term Paper Example Extensive research focusing and elaborating the significance and need of the freshwater bodies have expanded considerably during the past decade, although such critical information and knowledge gained has not been integrated so far, for the development of an efficient water management framework. However certain countries and regions such as North America, Chile, South Africa, the E.U. and Australia among others are an exception to this general rule, since these regions have witnessed the successful establishment of appropriate policies and approaches aimed at preventing the deterioration of freshwater and protecting the environment from further damage. In the face of adversities, and innumerable setbacks in the form of political and socio-economic measures, these policies are indicative of a struggle at the international level, to ensure better management of water together with the protection of the priceless ecosystems. Many water experts in the U.S. and other countries have argued that water markets, tradable water rights, and related economic approaches are important policy tools for improving the long-term sustainability of water uses and ecosystems. Water in existing times, has become an extremely rare and hence precious commodity, which supports the basic survival and sanitation needs of billions of people across the globe. The current issues related to environmental degradation which has taken a toll on global water bodies, has confronted the human population with strategic issues related essential for the sustenance of life on earth.

Gender in Organizations Essay Example | Topics and Well Written Essays - 2500 words
Gender in Organizations - Essay Example As a result, women remain different from men in that they put in more time and effort at the workplace and do more unpaid housework than their male partners. This is the main point raised by Ilene Philipson (2002) and David Schweingruber (2007), whose papers were selected as the two centerpieces of research for this essay because they capture the essence of the topic we want to discuss: that is, gender equality as it unfolds at work and at home today remains meaningless for the most part because of what both Philipson and Schweingruber call the "second shift," with Phillipson adding another factor called "familism." The first part of the main body discusses the dynamics of these two factors as to how they effectively distort the meaning of gender equality in the workplace. To illustrate the point, the last part of the essay's body looks into an actual case study of a married woman doing second shift work, tying this up to conditions in New Zealand, which is currently headed by a woma n president and where the women's movement is going great guns. ... Second Shift & Familism The dramatic increase in the labor force participation of women gave rise to the perception that we have finally entered an era that puts men and women on equal footing and makes no distinction between their sex and interests (Philipson, 2002). Women now hold jobs previously confined to men, such that there are now women police and soldiers, pilots, miners and even steel mill workers. Research since the 1960s shows that women's time spent on housework has been cut by nearly half while men doubled their time (Mickelson, et al., 2006). However, a closer look reveals that married women continue to suffer from gender inequality in the amount of work they do both at the workplace and at the house. In households with two wage earners, the women who enter the labor force continue to do more housework than men (Schweingruber, 2007). Women suffer from the same disadvantage at their paid job outside the home largely because of the mothering instinct that they bring to the workplace and creates special problems for their claim to gender equality (Fletcher, 2002). Even as a wage gap between working women and men persists, there is also a "leisure gap" between them at home (Bartley, et al., 2005). This crack in the otherwise greatly improved gender relations is traced to the "second shift" phenomenon, which is described by Philipson (2002) as the two work shifts of women: their unpaid job at home and paid job outside. Schweingruber (2007) defines the condition in more or less the same terms, relating it to the load of housework that married women perform on top of their shift of work outside the home. An important aspect of the second shift phenomenon is the way women develop an emotional attachment to their jobs and

Brown v. board of eduction Essay Example | Topics and Well Written Essays - 250 words
Brown v. board of eduction - Essay Example All of the other cases that are cited show that the courts were aware that there were many people in society pressuring the legal system about ââ¬Å"separate versus equalâ⬠. This goes against the desired code of the 14th Amendment. Finally Justice Warren and other judges realized that Negros deserved to gain education and the other case decisions could not give good reasons why blacks should continue to be segregated. The right to education is deserved for everyone regardless of their race and color. What Justice Warren is saying is that there have been many changes in society since the 1800s. It no longer made sense with a society that was developing for blacks to continue to be segregated in schools. Without having equal protections for education, they would always be thought as second class citizens. This court in Brown v. Board of Education did an excellent job of using education as a reason to finally begin the process of ending racial

Enhancements of IC Engines in Real-world Conditions
Enhancements of IC Engines in Real-world Conditions à Aatif Shaik, Aditya Upadhyaya R, Gowtham,à K N, Sachin B N Abstract ââ¬â Optimizing engine performance of IC Engines is a very shady field. Other than reputed companies Original Equipment Manufacturers (OEMs), who publish their reports, the rest of the industry does not throw much light into aftermarket modification field. As an end-user, a customer wanting to optimize his vehicle in terms of power, mileage usability is often mislead into buying products modifying his automobile that will produce no useful gains. This mini-project will be done on 2-wheeler motorcycles ranging from 150cc-350cc. It aims at bridging the gap between the products and the end-userââ¬â¢s knowledge of it. It will take on many such optimizing/modifying techniques, such as installing air-filters, spark plugs, exhaust systems, engine oils etc., and try to demystify what is actually happening there for the use of the said end-user. This mini-project will involve testing of various parameters of an engine, such as Brake Horse Power, Torque, Exhaust Emissions, Inlet Manifold Pressure etc., of a completely stock Engine. It is again tested after modifications for the same parameters. The results are then compared to give an outline of the effect of the modification. Each modification is done separately for the results to be completely independent of each other. All of the tests are conducted in real-world conditions, so as to ensure the reliability of the result. The final report (end of the project work) will give a much needed clarity on the modifications; will also comment on the safety of using such techniques and its cost effectiveness for the end-user. Market Situation ââ¬â In a stock motorcycle (factory-made, unmodified), it is so designed that the whole system is as generic as possible. That is, it is supposed to be appropriate for a wide-band of end-users. Taking this line, the manufacturers tune down most of the engine parameters in favour of mileage fuel efficiency, as these are the two major parameters that an end-user looks while buying the automobile. As time passes, the user, who now is accustomed to the automobile, might feel the need to enhance and optimize his automobile. He therefore researches about all the modifications that he can do to his automobiles, so as to increase the performance and efficiency. Parameters for testing ââ¬â Power produced (at the wheels) Torque produced (at the wheels) Fuel efficiency These parameters were chosen because of the following reasons ââ¬â Power produced at the wheel was taken, instead of engine power, because this gives an accurate idea of how the motorcycle will perform in the real world. It also includes the losses that will occur due to external conditions, and therefore will give a realistic feel to the test. Torque produced at the wheel was taken, instead of engine torque, because of the same reasons as above, that is, it will give an accurate idea of performance in the real world. Fuel efficiency is an obvious factor and a parameter to be considered, as most endusers will ultimately look at this for their decisions. It gives an indication of how well the engine is taking the modifications and will also represent whether the modification done is cost-effective or not. Specifications of modifications used ââ¬â Results ââ¬â Air filter modification For load testing, there is a 1.11sec difference in acceleration timings, in partial load conditions. Whereas, there is a 1.24sec difference in acceleration timings with full load condition. In both cases, the modified motorcycleââ¬â¢s timings were better. For the crispness of throttle, it was seen that the modified setup has a better crispness than the stock setup. For initial fuel efficiency, it was seen that the stock setup fared better than the modified setup. For the cold starting test, it was seen that there is no difference between stock and modified setup. Dyno test Synthetic Oil modification ââ¬â For load testing, there is a 2.25sec difference in acceleration timings, in partial load conditions. Whereas, there is a 2.17sec difference in acceleration timings with full load condition. In both cases, the modified motorcycleââ¬â¢s timings were better. For the crispness of throttle, it was seen that the modified setup has a relatively better crispness than the stock setup. For initial fuel efficiency, it was seen that the stock setup fared better than the modified setup. For the cold starting test, the stock setup fared badly, whereas the modified setup. Dyno Test ââ¬â Exhaust Muffler modification For load testing, there is a 2.1sec difference in acceleration timings, in partial load conditions. Whereas, there is a 1.65sec difference in acceleration timings with full load condition. In both cases, the modified motorcycleââ¬â¢s timings were better. For the crispness of throttle, it was seen that the modified setup has an extremely good crispness when compared to the stock setup. For initial fuel efficiency, it was seen that the stock setup fared better than the modified setup. For the cold starting test, it was seen that there is no difference between stock and modified setup. Dyno Test ââ¬â Discussions ââ¬â Air Filter ââ¬â The modified setup performed better than the stock setup, because of the extra amount of air going into the engine cylinder. This allowed the fuelinjected to calibrate and add more fuel to the air-fuel mixture, thereby gaining power. In the modified setup, as there is no restriction, aside from the filter material, the engine was free to suck air to its maximum capabilities, allowing the fuel-injection system to inject more fuel, thereby increasing power and torque. This is seen as the constant increase throughout the power-band. The crispness of throttle was better in modified setup because the lesser obstruction in the intake system, which allowed air to be sucked in freely. Cold-starting was not affected because of the fuel-injected system, which automatically calibrates the appropriate amount of fuel to be injected in all conditions. Synthetic Oil ââ¬â The modified setup performed better than the stock setup, as the synthetic oil gives better lubrication than the stock setup. This is due to the inherent nature of the synthetic oil, which provides better lubrication and wear-resistance throughout all temperatures with respect to stock mineral oil. The crispness of throttle was better in modified setup because the lesser friction, which allowed that engine to rev freely and quickly. Due to greater lubrication, lesser friction was present, thus minimizing friction losses, which attributed to the higher power and torque output in the modified setup. Cold-starting was better in modified setup, as the inherent nature of the oil made less viscous allowing it to start freely and quickly, compared to stock setup. The synthetic oil also kept the engine temperature lower than the stock setup, thus further helping it to work efficiently. Exhaust Muffler ââ¬â The modified setup performed better than the stock setup, as the free-flow exhaust muffler allowed the exhaust gases to flow out more freely than the stock setup. This allowed the piston to have lesser load on it to push the gases out, therefore giving a higher power and torque output. This can be seen in the consistent increase in power and torque from 3500rpm. As the load on the piston decreased, the engine was allowed rotate freely, thus giving it a more free nature, whereas the stock setup constricted the engine very much. The crispness of throttle was better in modified setup, because of the free flowing gases in the exhaust system, which allowed that engine to push more and more gases out for the same rpm. Cold-starting was not much different compared to stock setup, as the starting depended on initial air-fuel mixture temperature, which doesnââ¬â¢t get affected by this modification. Final Conclusion ââ¬â It depends on the end-user on whether he wants to do certain modifications. From the results and discussions, we can see a general increase in performance for all the modifications used, provided those are done under correct procedures. These results were fairly satisfying, and also laid to rest some of the general misconceptions that were attached to such modifications. Apart from power enhancing, the mini-project also tried to bridge the gap between the aftermarket modifications and the customerââ¬â¢s knowledge of it. Dealing with how the actual results of how a modification might work-out and whether their claims were correct. It is concluded that the manufacturerââ¬â¢s claims of increasing power and performance which are indeed true, But the manufacturer also claims increase in mileage which is not true since it comes with of a small drop of mileage. If the end-user can adjust with the drop, then they can find the modifications useful. References Effect of Intake air filter condition on vehicle fuel economy.

John Steinbecks The Grapes of Wrath :: John Steinbeck Grapes Wrath Essays
John Steinbeck's The Grapes of Wrath Throughout his book, the Grapes of Wrath, John Steinbeck employs the principles of Foucaultââ¬â¢s theory that power exists as a result of consent. This is particularly the case in the relations between the Joad family. Chapter ten includes specific scenes in which the family membersââ¬â¢ assumed positions of power are focused on and explained. When Jim Casy asks if he can accompany the Joads on their migratory trip to California, Ma looks to Tom to speak, ââ¬Å"because he [is] a manâ⬠. Ma is clearly consenting to Tomââ¬â¢s power over her as a male figure, not because he told her he had the right to speak first, but because she allowed him to hold that prerogative. Foucault also argues that identity perception is related to various modes of discourse that are specific to historical eras; apparently, the idea that women are subordinate to men has been established in behavior, media, or any other entity that influences the way people think. When the rest of the Joad family returns on the truck after attempting to sell the last of their belongings, Steinbeck uses three pages to describe each family memberââ¬â¢s place on the truck and why they belong there. Al is the ââ¬Å"proud and serious and efficientâ⬠driver of the truck, earning the familyââ¬â¢s respect for his responsibility in manning the vehicle. This exemplifies Foucaultââ¬â¢s idea of transaction: the family consents to Alââ¬â¢s power because they will be affected if the truck malfunctions. Rose of Sharon is a balanced, self-satisfied, and all-knowing woman whose husband, Connie, is alarmed by the dramatic change in her behavior since the onset of pregnancy: although he once controlled her, he now feels weakened in his power because he has let her complacency control him. Pa and Uncle John, as ââ¬Å"heads of the clan,â⬠sit in the ââ¬Å"honor seatsâ⬠beside Al; however, Uncle John secretly wants Rose of Sharon to take his pla ce because he is uneasy inside and knows she is surer of herself. Uncle Johnââ¬â¢s power is one of dogma, while Rose of Sharonââ¬â¢s is self-asserted. The entire Joad family then holds a council meeting to discuss their plans for departure. Again, everyone has his or her ordained placement: the men squat in an inner circle, while the women stand around them.

Fight against Oppression on Women Essay
Todayââ¬â¢s sexismââ¬âfrom widespread violence and degrading ideas to inequality at the workplace and unpaid labor at homeââ¬âreaches into every corner of our lives. Womenââ¬â¢s oppression stems from the nature of our deeply unequal society, and a system that needs to divide and conquer in order to survive. People of all genders are fighting back! Grassroots mobilizations against sexual assault, victim-blaming and attacks on our reproductive rights are providing a glimpse of the potential to build a new movement for womenââ¬â¢s rights. From Egypt to Yemen to Madrid, women are demanding a place at the forefront of struggles for democracy and economic justice. Sexism in our society leads to multiple negative outcomes for women. Although traditional therapeutic approaches as well as preventive interventions address the specific negative outcomes of sexism, they rarely utilize a social justice approach. The deleterious effects of sexism occur complexly; sexist interpersonal events often occur within family systems that may endorse traditional gender roles, which exist within a societal and cultural context that contains formalized sexist policies. These multifaceted, ingrained circumstances delineate the need for preventive social justice to address sexism on multiple levels. As our society continues to evolve, with the advancements in technology, so does sexism and discrimination. It is just molded differently to accommodate our modern day society. Women do two-thirds of the worldââ¬â¢s work for only five percent of the income, according to Unifem, the United Nations Development Fund for women. Today young women across the world grow up to expect less educational, economic and political power than their male counterparts. Half the worldââ¬â¢s citizens, women in the 21st century still only represent a tiny minority in democratic assemblies. Domestic violence, civil wars and international conflicts continue to destroy womenââ¬â¢s freedom, power and security in particular. And yet women find themselves systematically excluded from international diplomacy and peace discussions. Womenââ¬â¢s rights may be enshrined in human rights declarations and egalitarian constitutions around the world, but in global terms of power and independence they are sec ond class citizens.

Senior Privileges
In the past, my high school gave more privileges to the seniors, although they have taken the privileges away from the seniors every year one by one. Currently, the only privileges seniors have over the underclassmen are leaving five minutes early for lunch and having the senior courtyard for lunch. We believe seniors should have more privileges or benefits than the school gives to us. After EHS took away senior privileges like going off-campus for lunch and leaving class five minutes early, students rebelled and started to sneak out for lunch saying they have Career Center or GHS third block. Although the administration started to notice the students coming back after thirty minutes, the students started to be dismissed to continue going off-campus for lunch. The problem with not leaving class early is that students began sneaking out of class and detention numbers increased because sneaking out is not allowed. The senior class can relate to this issue and would like to go off-campus for lunch and leave class five minutes early. The future upcoming seniors would also like the same privileges. The current seniors have looked forward to senior benefits since being a freshman. By the time the freshmen class finally reached senior status all of the privileges the previous seniors had gained were taken away due to misjudgment and carelessness. The administrationââ¬â¢s defense is that the seniorsââ¬â¢ of previous classes disregarded safety concerns. Although high school students normally disregard the administrationââ¬â¢s safety concerns one of the purpose of being a senior is to understand safety before they enter the real world. Although safety is a current issue we believe seniors are capable of being careful and influencing the underclassmen of being cautious. EHS may be responsible for the students during the day; we believe that students and parents can sign a permission slip where if the student gets in a wreck while out for lunch then EHS will not be responsible for any injuries. We believe seniors understand that going out for lunch is a privilege and if there are any complaints or problems the studentââ¬â¢s privileges can will revoked at any point of time. We believe senior privileges can be taken away if senior abuses their privileges then they will have their privileges taken. Although previous classes have acted in a way that they would have been revoked eventually the administration should consider giving privileges back to seniors. We believe having senior benefits will cut down on the discipline issues EHS may have to deal with. EHS should offer more senior privileges than mentioned above. We think administration could add a few more benefits for seniors such as having a free period during the day, if the senior has Aââ¬â¢s and Bââ¬â¢s they could leave campus for the period. Although it would be mandatory for students to receive permission by parents and for the students to sign out when they leave campus and back in when they come back on campus for the rest of the day. For students that do not have the required grades and permission they can use the period to study and bring up their grades to earn the right to go off campus for the period. Our idea is right because it helps rebelling out of the schools and it will slim down the discipline issues of the seniors. It will also help the seniors prepare for college or the working world next year.
