Windows 95 Beats Mac Essays - Microsoft Windows, Operating System

Windows 95 Beats Mac Over the years, there has been much argument over which computer platform to buy. The two contenders in theis competions have been the PC , with its Windows environment and the Macintosh. Now, with the successful release of Windows 95 for the PC, this has been the mjor argument for each side : hardware configuration, networking capabilities, and operating system. The first arguments to look at between the Pc and Mac platform has to do with hardware configuration. Before Windows 95, installing and configuring hardware was like pulling teeth. The instructions given to help install hardware were too complicated for the average user. There was also the issuer of compatibility between the large number of different hardware setups available in the PC world. Is a particular board going to work with my PC? With Windows 95, these problems were alleviated with plug and play technology. With plug and play compatible boards, the computer detects and configures the new board automatically. The operating system may recognize some hardware components on older PCs. Mac userw will claim that they always had the convenicnce of a plug and play system, ubt the difference shows in teh flexibility of the two systems. Another set of arguments Mac users use in favor of their sysstems over PCs is in multimedia and networking capabilities. Mac users gloat that the Mac has networking technology built in the system. Even if a user did not use it, the network is included with the system. They cited that for the PC users and Pc users hate the fact that they need to stick a card in their computers to communicate with any other computer. With Windows 95, the Mac network gloaters are silenced. Windows 95 included built-in network support. Any network will work properly. The Mac users also claim their systems have speech, telephony, and voice recognition, whereas the Pc user does not have. In truth, the promised building blocks for telephony control do not yet exist. I think the speech is not good point in the Mac. In the world of computer, people cannot stand still for too long without getting passed by. Windows 95 now threatens the only assets the Mac has in capturing the interests of the consumers because of configuration in the hardware, communication betweencomputers and difference of operating systems in both platforms. Almost any argument could give in defense of the Mac does not carry nearly as much bite as it did before Windows 95 arrived. Pc users have something to be proud of.

The life and works of Margaret Mead

The life and works of Margaret Mead Margaret Mead was a sociology scholar, an eminent anthropologist, a scientist and a great author on anthropology, sociology, religion and ancient society’s issues. She was an intelligent woman and used both knowledge and action to achieve her goals. She was also involved in politics and helped many presidents in formulating policies in ecological and nutrition matters. Advertising We will write a custom research paper sample on The life and works of Margaret Mead specifically for you for only $16.05 $11/page Learn More As a politician she served as an ambassador, without a portfolio, to many presidents in the areas of ecology and nutrition something that gave her the title, Mother of the World in 1969.Her works are still used in learning by students and also for understanding various issues that characterize the world today. She was born in Doylestown, Pennsylvania, to a religious family and both of her parents were sociologists. She was dropped out D ePauw University in 1919 after one year of studying and then joined Barnard College where she graduated with a Bachelors degree in 1923. She did her masters at Columbia University with the help of Professor Franz Boas and Dr. Ruth Benedict and later received her PhD from the same university in 1929. She was married three times; once to a fellow student, then to an anthropologist, Reo Fortune, who divorced her because she could not give birth to children then. Her third marriage to Gregory Bateson an anthropologist was the best according to her, and their daughter, Mary Catherine Bateson also decided to follow in their footsteps and became an anthropologist. She closely worked with her husband and even went to Bali for field work with him, they were married for fifteen years then divorced and when questioned about this she said that was her best marriage and that, American women are good mothers, but they make poor wives (Lapsley 1999). She defended women rights in her writings an d also educated them on child rearing and many other family issues. She filmed the life of her daughter since childhood and observing her grow assisted in writing many of her publications. She was also recognized as a national and an international leader and at a time the president of the following major associations: American Anthropological Association, Anthropological Film Institute, Scientists Institute for Public Information, Society for Applied Anthropology and the American Association for Advancement of Science. Mead lectured at the New School and Columbia University1954 to 1978, and she was the chair of the department of social sciences at Fordham Universitys and founded founding their anthropology department in 1968.Advertising Looking for research paper on biography?

Mead is one of the major contributors in the sociology discipline she has done a lot of research and wrote about families, children and the male and female gender. Her works have been used in understanding problems and issues that face families and also gave an insight on how to solve them. She also has made it possible for sociologists to understand societies and how they influence an individual’s life, not forgetting also her commitment to find solutions to the global social issues facing the world so as to make it a better place for people to live in. Her greatest works that made her known were the most controversial books â€Å"Coming of Age in Samoa† and â€Å"Sex and Temperament in Three Primitive Societies†. In the first book Mead wanted to understand adolescence and determine whether it is the same for all individuals worldwide. Her goal was to answer t he question â€Å"Are the disturbances which vex our adolescents due to the nature of adolescence itself or to the civilization? Under different conditions does adolescence present a different picture?† (Caton 1990). In her survey, she went to Samoa in a village of 600 people where she interview 68 adolescents between 9 and 20 years. She found out that adolescence for them was a peaceful change with no emotional or psychological misery, apprehension, or disorder as it happens in the United States. She also realized that the Samoa girls were better child raisers than Americans. When she published the book, many westerners were offended by the findings and claimed them to be false; with others even going to an extent of going back to Samoa for more research and claim that some of her informants say that they were forced to give false answers. Her colleague, Franz Boas, defended the book and said that â€Å"courtesy, modesty, good manners, conformity to definite ethical stand ards are universal, but what constitutes courtesy, modesty, very good manners, and definite ethical standards is not universal. It is instructive to know that standards differ in the most unexpected ways (Caton 1990). The other book â€Å"Sex and Temperament in Three Primitive Societies† was about three societies in which she studied the nature of women and men. One of the societies was Chambri, (Tchambuli) in Papua New Guinea where women are dominant that menAdvertising We will write a custom research paper sample on The life and works of Margaret Mead specifically for you for only $16.05 $11/page Learn More The men primped and spent their time decorating themselves while the women worked, did all the chores and were the leaders of the society without causing any problems completely opposite of what was happening in America then. In the other society Melanesia males were dominant and also some few women who mostly were witches hence making both gend ers equal and similar in temperament. The other community Arapesh was different; both genders were nonviolent and avoided war although sometimes they went into war with other communities when necessary. The society share land, brought up their children together and relationships among relatives were good. She therefore concluded that temperaments were communally instilled into people and they were not personal. Mead continued writing and some of her major works were: Male and Female: A Study of the Sexes in a Changing World, after observing the behaviors of people in the South Pacific and the East Indies. She said we know of no culture that has said, articulately, that there is no difference between men and women except in the way they contribute to the creation of the next generation. Her other books include: An Anthropologist at work (1959), which was about her friend and colleague Ruth Benedict, The memoirs Blackberry winter (1972), and A rap on race (1971). Controversies have r isen concerning her relationship with Benedict because some people have claimed that she was bisexual and her daughter confirmed that by saying that their relationship was a little sexually due to the letters they wrote to each other. In her life Mead did not state her sexual orientation although she had mentioned in her writings that an individual can decide to change it later in life. She died of cancer in 1978 and she was buried at Trinity Episcopal Church in Buckingham, Pennsylvania. Her greatest legacy is the Presidential Medal of Freedom awarded by the former President, Jimmy Carter. â€Å"Margaret Mead was both a student of civilization and an exemplary of it. To a public of millions, she brought the central insight of cultural anthropology: that varying cultural patterns express an underlying human unity. She mastered her discipline, but she also transcended it. Intrepid, independent, plain spoken, fearless, she remains a model for the young and a teacher from whom all may learn.

Essentials of Public Speaking Fifth Edition Cheryl Hamilton Tarrant country collage-NE Campus - Essay Example This is because sometimes the government relies on certain citizens for contribution; chances to present a speech are almost unlimited. Not only does learning to present speeches is an advantage to the society, but also it helps to improve our careers, many companies have their speaker bureau of which they use them to release their message to the public (Hamilton 6). An example of public speaking includes announcements. When analyzing an audience, first, I conduct a poll that will determine if the audience is familiar with the topic of discussion. I have learnt that I should get to know the audience beliefs, morals, values, sex and age. Moreover, I have learnt to make sure to know what type of audience I have, and plan on how to make them listen to me and still remember. In addition, while researching, I make sure that I do it thoroughly and take notes. In addition, I have learnt to include names of author and page numbers where necessary (Hamilton 71). The best way to improve active listening as described in chapter two and three is by involving my audience (giving them an emotional stake) in what one is saying there are likely to listen attentively to your speech (Hamilton 57). Practice reduces speech anxiety because when one practices they feel more prepared. Speaker anxiety is a feeling of nervousness and uncomfortable while speaking before an audience. Most speakers that undergo speaker anxiety feel that it is almost awkward to get rid of, but the experienced speakers know how to overcome speaker anxiety. One can use negative emotions for example fear, guilt, shame or anger, but one can still use positive emotions such as joy, relief, hope or compassion. One must also make the audience feel there is something in our speech that will benefit them. If a speaker needs his or her audience to trust and understand the hummer and the information in their speech, they need to do the following; they

Abstract Strategic human resource management is, undoubtedly, an integral factor in organisational success but, it only represents an element within the... 1.1: Introduction Focusing on the prevalent organisational structure and management distinctions between the private and the public sector, the dissertation aims to demonstrate the tendency of the public sector to adhere to outmoded and inefficient management models as compared to the best practices models, strategies, tools and mechanisms adopted within the private sector. The disparity between public and private sector management styles and paradigms is customarily justified through reference to organisational structural differences. This dissertation takes a contrary position, arguing that even though there may exist structural differences between public and private sector organisations, the differences are not such as to prevent the successful implementation of private sector management strategies and paradigms in public sector organizations, as would allow for the adoption of Total Quality Management lending to the evolution of an effective and efficient human resource. These statements and argum ents shall be validated through a review of the literature on public and private sector organisations and contemporary management strategies and, solidified through the results of the field study. 1.2: Importance of Topic The current study proposes to examine the similarities and differences between the public and the private sector for determination of whether or not private sector management strategies withstand successful adaptation to, and implementation in, the private sector.

Discussion questions - Article Example I agree with the constituencies who argue that the flag preserves the fallen heroes’ legacy. On the other hand, the heroes represented by the flag were against the civil rights which promote racism in the region. The governor should, therefore, remove the flag to reduce cases of unrest and discrimination in South Carolina (Eugene 2011). Q2. Policy making is one of the toughest process lawmakers, and policy implementers go through in any given region. This is because; there are conflicts with respect to the views of various policy makers. Every person is mandated to personal opinion which leads to conflicting versions in the policy making process. It also clear that, some problems in society are not public problems considering the place the place that experiences the problem (Peter 2001). Q3. Regionalism is an approach in policy making that promotes the idea that some problems in the society are not public issues. This is because, the problem affecting a particular region do not affect other regions equally (Eugene 2011). Regionalism has various benefits in problem-solving across the country. For example, the issue of Marijuana consumption and peddling in the U.S has found a solution through implementing laws that legalize its use in the rampant states of Washington and Colorado. This makes it easier for the government to control the use of Marijuana in the specified states. Regionalism is effective in controlling cartels dealing with distribution of the drugs in Colorado and Washington. This is because it helps in eliminating other criminal activities accompanying illegal sale of Marijuana (Peter

Green Telecommunications Reducing Opex And Capex Engineering Essay

Green Telecommunications Reducing Opex And Capex Engineering Essay In the last 10 years, mobile and wireless communications have seen tremendous growth. The growth in the networks along with fierce competition has led the telecom operators to focus on logistics, security and costs. Since each operator competes to provide the customer the best service possible at minimum price, reducing operating costs is of prime importance. In addition, environment has also become a major issue worldwide affecting most of the telecom operators. Legislative pressures and the potential for Carbon trading revenues are causing the Mobile Telecommunications Industry to become mindful of its impact on carbon emissions. Green considerations are coming into prominence in network design. This paper discusses various eco-friendly solutions in network design to reduce CO2 emissions leading to reduction in Operating Expense (OPEX) and Capital Expense (CAPEX). Introduction Telecommunication Industry has helped the world in a big way to reduce carbon emissions by reducing unnecessary business travel, improving efficiency of freight transport and other logistics. The carbon footprint of a mobile phone call or video conferencing is thousand times smaller than the environmental impact of travel required for personal meeting. However, running these telecommunication systems also creates a load on the environment contributing to about 0.5% of global carbon emissions. Though, this is much less as compared to the other industries, it has brought in a lot of criticism from various environmental agencies and green campaigners. In addition, powering these systems makes up half of a telecom operators operating costs and with energy prices rising, these expenses are hurting the profits of the operators. The only solution for the Telecom Operators to jump out of this situation is to adopt Green Technology in the networks. This will not only reduce the OPEX and CAPEX of operators substantially but also lead to energy-efficient and self-sustainable telecommunications systems. Energy Concerns for Telecom Operators Today, around 50% of the operating costs of a network company goes into electricity. With electricity prices rising, it is eating a lot into the revenues earned by these network companies. The various network elements that contribute to these costs are the Radio Base Stations, the equipments used in the network and the mesh of connecting cables required to interconnect Fixed-Line operations. Out of these, Radio Base Stations account for two-thirds of the power costs with the equipments being the second largest contributor. Along with increasing costs due to excessive power consumption, network operators also contribute significantly to the carbon emissions. In order to overcome these issues, the operators must look at developing sustainable network solutions. The following steps such as developing energy-efficient products and features, creating energy-efficient site solutions, designing energy optimized networks and harnessing alternative sources of energy can help pave the way for telecommunication operators towards sustainable growth. Developing energy-efficient products and features Many network equipment providers these days have developed or are in the process of developing products that are eco-friendly. Apart from this, many new features are also being developed so as to minimize energy consumption during operations. Ericsson, Nokia Siemens Networks and Motorola are some of the significant contributors to this new generation of energy-efficient products. Ericsson has developed an innovative design for housing Radio Base Stations called the Ericsson Tower Tube. The Tower is made from concrete which has a lower environmental impact than traditional steel, consuming up to 40 percent less power from a life cycle perspective. This is due to the fact that concrete results in less energy consumption and CO2 emission than steel during production and transport. However, the most important part is that during operation, feeder losses are substantially reduced, and no active cooling is needed. Thus, adopting a solution like this, helps operators to not only reduce their construction and power costs but also reduce their capital expenditure as active cooling units are not required. Nokia Siemens Networks, on the other hand, has developed the award-winning Flexi Multiradio Base Station. The unique capability of such a Base Station is that it can support all the 3GPP technologies i.e. GSM/EDGE and WCDMA/HSPA to LTE in a single unit with all running simultaneously. This technique of running multiple radio technologies in a single Base Station leads to multiple advantages for operators such as reduced OPEX from fewer site visits, simplified logistics, reduced maintenance and a smaller requirement for trained staff. In addition, this concept can also reduce the carbon footprint of a single Base Station by 70% which corresponds to approximately 70 GWh of annual energy saving. Another important advantage is that it is only 20% of the size and weight of a conventional base station leading to reduction in the carbon footprint from transportation and installation. Due to reduced size, it is possible to install base stations in places previously considered impossible such as densely populated urban areas thus saving space, installation time and costs. Flexi, as it is called, has been designed so that it can function even without external air conditioning, thus reducing around 30% in site energy consumption. Its other prominent features like software-based capacity and capability upgrades further help in reduction of operating expenses as Flexi can be controlled via remote software whereas conventional base stations require site visits and sometimes hardware replacements. Furthermore, the Flexi Base Station can work on renewable energy such as solar or wind power. Like other Nokia Siemens Networks products, Flexi has been designed so as to facilitate ease of recycling at end of its life. This also helps solve the various end-of-life problems that many operators face. Apart from hardware products, new software technology can also help to improve energy efficiency of base stations. Ericsson provides the Base Transceiver Station Power Savings feature while Nokia Siemens has its NetActà ¢Ã¢â‚¬Å¾Ã‚ ¢ Service Quality Manager (SQM). Ericsson has introduced the new Base Transceiver Station Power Savings feature in many of its base stations across the world. Due to this feature, during low-traffic periods, the radio resources of the network that are unused are put into Stand-By mode, thus lowering energy consumption. Depending on the network traffic patterns, this feature can reduce 25% of energy consumption. The added advantage of this innovation is that it can be installed in any of Ericssons existing Base Stations by a mere software upgrade. Thus, if this feature is installed in all the existing Ericsson Base Stations, it can reduce carbon emissions by 1 million tons a year. The Nokia Siemens Networks NetActà ¢Ã¢â‚¬Å¾Ã‚ ¢ Service Quality Manager (SQM) is used to provide better control of BTS power settings. The night time power saving feature allows an operator to set a time when traffic prioritization is enabled in the network. NetAct SQM will control the operation automatically according to pre-configured settings, such as Schedule and BSC/BTS list. By using such a feature, a network operator with around 10,000 base station sites can potentially save the average energy consumption of 1000 households per year. Translating this into monetary values would suggest an estimated à ¢Ã¢â‚¬Å¡Ã‚ ¬5,000,000 annual savings in OPEX, an estimate which naturally depends on the marketplace. Designing Energy Optimized Networks Another key aspect for network operators to look into is energy-efficient network design and planning. More often than not, operators tend to design networks with as many as Base Stations in order to provide maximum coverage and signal strength. However, by taking into consideration the challenge of providing almost the same amount of coverage with less number of base stations can help telecommunication operators achieve optimization in their networks. With optimized networks, the operating costs of operators can come down drastically as the number of base stations can be reduced by 30% 50%. Now, a sustainable network has its foundation in good design. At the core of any efficient and sustainable network is good design. Without doubt, the best way to achieve an optimized, energy-efficient network is to build it on good foundations, based on sound design principles. Even if a company achieves energy efficiency at the component level it does not mean that it can make up for an inefficiently designed network, in which the number of radio sites could potentially be double than what it needs to be to achieve the same coverage with the same quality. By hiring experienced network designers to become involved from the start of the design process, operators can typically reduce the number of radio sites needed overall by between 30 and 50 per cent. Energy-Efficient On-Site Solutions There are many areas on-site where energy efficiency can be achieved. By adopting certain ingenious and innovative solutions, a lot of unnecessary energy wastage can be avoided and thus costs can be reduced. One of the main causes of power consumption on-site is the air-conditioning required for cooling the telecom shelters that contain the radio equipments. These air-conditioning units consume anywhere between 1200W 2000W. However, with recent developments, the radio base stations can endure higher temperatures thus enabling new cooling techniques to be used. One solution is to have heat exchangers which can efficiently transfer heat from one medium to another. Thus the heat generated by using the Radio Base Stations can be captured by the heat exchangers and transferred to the water kept outside in a tank. This method of heat removal can help maintain temperatures 20oF to 15oF less than ambient. Also, it does not require any power source as heat is dissipated by means of natural convection. This method can be used in dry regions mainly in North-Western India. Another innovative solution that can be used in tropical regions is Phase Change Materials (PCM). These help in maintaining tem peratures in the shelters between 20oC to 35oC without use of any air conditioning system. Thus, implementing innovative solutions for cooling telecom shelters, a telecom operator not only reduces its OPEX (due to reduced energy costs) but also CAPEX by minimizing the amount spent on equipment needed for cooling. Another area where power can be conserved is by minimising the Feeder losses. This can be established by placing the Radio Base Stations closer to the antenna. Since feeder loss is minimised, it helps in improved network coverage and capacity. This, in turn, helps the operator to reduce the number of RBS in the region leading to network optimization. The Ericsson Tower Tube discussed above implements this solution in an efficient manner. The tower consists of an elevator. The base stations are installed at the bottom of the tower and then lifted by the elevator to top where they are operated. Thus by being close to the antenna the feeder loss decreases. Harnessing Alternative Sources of Energy With conventional energy prices rising, operating telecom networks is becoming very difficult for the operators. The rising operating costs are affecting the bottom lines of the network operators. Apart from this, there are various sites which are beyond the reach of electricity or have unreliable electricity provision. Thus, operators need to set up diesel powered base stations in these regions. However, regular maintenance and refuelling the diesel becomes a very costly affair. In order to overcome these issues, a single solution is available at hand i.e. harnessing alternative sources of energy to power the telecommunication systems. There are various renewable energy sources that can be used efficiently these days. This includes Solar, Wind, Biofuels, Fuel Cells etc. Solar As the cost of Solar technology continues to fall, it is becoming a very popular technology to be used as primary power source for various base stations. Though the initial capital expense (CAPEX) is higher for a solar-powered site, however, over a period of 5 years the Total Cost of Ownership (TCO) for such a site is 30% less than a conventionally powered site. Also the life span of a solar powered BS is higher than a usual BS, thus in the longer run the network operators can reap more benefit out of this solution. A key point in using Solar technology is also the fact that its maximum outputs align with the maximum load on the telecom networks. In other words, the peak of mobile phone calls overlaps with the peak of solar power and at night when the mobile phone usage tends to drop, the solar power switches to battery phase. Solar energy can be prominently used to its best effect by regions coming in the equatorial sun-belt. And this is where most of the emerging markets, like India and China are located. Thus network operators in these markets can readily adopt solar technology and reduce their OPEX by huge amounts. With the extensive competition in these markets, an operator adopting this technology can forget about the power related costs of the OPEX and focus on improving customer satisfaction. Major network solution providers like Motorola, Ericsson and Nokia Siemens have developed various techniques to provide solar technologies to various network operators. Ericsson has developed a special Radio Base Station (RBS) for solar power called SunSite. A typical RBS requires 142 W of power; 110W the RBS itself, 20W transmission equipment and 12W Obstruction lights. Thus, Ericsson developed a solar system that can provide this much amount of power. The first solar powered site delivered by Ericsson was in the year 2000. Since then it has delivered 200 SunSites in various countries. Now that Ericsson has also developed energy-efficient RBS, sites have become more energy-lean. As a result, the large solar panels are no more used. Instead small solar panels are effective enough to provide the required amount of power. This is reducing the costs for setting up SunSites and thereby reducing CAPEX for the operators. A very good example in case of Ericsson Sunsite was the set up for Telekom Indonesia which was a 100% solar powered site. The SunSite helped Telekom Indonesia reduce its energy consumption by 60% and also made the site almost maintenance free. This led to decrease in power costs, fuel costs and maintenance cost leading to reduction of 40% in the OPEX. Nokia Siemens has also developed its Renewable Energy Source (RES) Autonomous site solutions. It provides various options like Standalone Solar Sites, Solar-Wind hybrid sites and sites with a combination of Solar-Diesel Generator. Motorola has also recently developed its solar solutions under the name Horizon II DC Macro/Mini BTS. Wind Wind is a plentiful resource across all regions of the world with varying degrees of intensity albeit considerably stronger in coastal regions. The main drawback to wind energy is the reliability of the source which is the main reason we do not use wind as a standard power source. Coupled with solar energy and the reserves in battery bank storage, wind does continue to provide an abundant, free-to-use, easy to access and environmentally friendly means of supplying power for the Autonomous Sites. Wind turbines can be placed in different configurations at the site. An early site analysis will determine the ideal turbine configuration as well as the correct direction and height to maximize the energy output from the turbines. Moreover, many governments offer tax benefits and direct subsidies for wind and solar energy expenditures making wind an ideal solution in most situations. Wind power has very low operation expenditure. BioFuels Biofuels are liquid fuels that are derived from plant materials. These fuels are entering into the market, driven by factors such as fuel price rise, reducing carbon emissions and the need for increased energy security. Ericsson has pioneered the use of biofuels in telecoms. For instance, Ericsson, Idea Cellular and the GSM Association Development Fund have launched several base stations powered by locally produced biofuels to extend Ideas commercial mobile network in rural India. They are being deployed at greenfield sites that have not previously had access to a mobile network and are located in areas with unreliable power supply. The biodiesel for these base stations comes from used cooking oils from restaurants. Idea currently has 23 sites running on biodiesel in India, and hopes to expand this to 40 to 50 sites. In the long term, it is expected that locally produced jatropha oil will be used, as soon as this is available in sufficient quantities. The selected sources for biodiesel have low environmental impact and follow responsible environmental practices for the production of biodiesel. Fuel Cells Fuel cells are also being developed so as to efficiently use them as a source of energy for telecom networks. In recent years, a lot of improvement has been done in the Fuel Cell technology which has led to many benefits over generators such as fuel efficiency, climate resistance, reliable start-up, and compact size. They operate at very low noise levels. Due to this, there is no indication of a power source running on the site and hence reducing the likelihood of theft also. With development, fuel cells are being manufactured in great numbers due to which its cost have come down considerably as compared to engine driven fuel cells. Operation of a fuel cell is to convert any fuel, like Hydrogen into electricity without combustion. There are several types of fuel cells, of which the most useful telecommunications is the Proton Exchange Membrane Fuel Cell (PEMFC). The PEMFC operates at low temperatures and runs at 40-60% efficiency. Motorola, which is involved in fuel cell research for networks and mobile devices, is also exploring micro fuel cell technologies as a replacement for rechargeable batteries in mobile devices. In partnership with various companies, Motorola is developing technologies such as: Hybrid fuel cell technologies for radios A hydrogen generator as a miniature fuel-cell power source5 Improving PEM fuel cell performance, durability, and manufacturability using single wall carbon nanotubes (SWNTs) Fuel cell technology is maturing and advancing rapidly. However, a disadvantage for fuel cells is that at higher loads, cooling is required. Thus a trade-off has to be made in reducing the OPEX due to low operating costs for using fuel cells and increasing CAPEX due to extra cooling units required. End-of-life Solutions Technology, today, is changing so rapidly that in a very short span time the network equipment becomes old and needs upgradation. In these situations, network operators often feel pressurized to dispose old equipment and set up the latest one. However, this can create a lot of strain on the OPEX and CAPEX and also have a negative impact on the environment. Thus, the network equipments providers these days provide solutions to cater to the end-of-life scenarios as well. Nokia Siemens provides Asset Recovery Service which is based on recycling of old equipment and refurbishment of existing network elements. There are two modules in the Asset Recovery Service. Recycling Service module looks into the proper waste disposal of old equipments in an environment friendly manner. The Refurbishment Service Module looks into the upgradation or extension of lifetime of existing network equipments. The benefits to the customers include: Reduced obsolescence cost Development of new technology is always good for the industry. However, the problem is the piling of obsolete equipment. Using Asset Recovery Service, the obsolete inventory can be converted into useful, re-usable equipment. Environmentally Responsible Approach Due to tight regulations regarding disposal, it creates a problem for the companies to get rid of old elements. Thus, this service helps customer to dispose in an environmentally sound manner. OPEX and CAPEX savings By reducing warehousing cost for obsolete inventory, OPEX can be saved. Also due to the Refurbishment Service, the need to spend on new equipments reduces, thus CAPEX can also be saved. Carbon Credits By reducing their carbon emissions, telecom operators can also exchange them for carbon credits. One carbon credit is equivalent to one tonne of carbon dioxide. And one carbon credit is priced in the markets at around 22 Euros (price fluctuates according to market). This concept of carbon credits is very favourable for companies operating in the developing countries as according to Kyoto Protocol, there is no restriction on these companies to limit their emissions. However, all the developed countries (except US as it has not signed the Kyoto Protocol) have to restrict their emissions by 2012. They can achieve this by either implementing new technology to reduce their emissions or by helping companies in the developing countries to reduce their emissions and buying the carbon credits that are obtained. As there is a very huge scope for reduction of carbon emissions in the Telecommunications industry, all operators in developing countries can immensely benefit from carbon credits. Also, as the deadline year 2012 nears, it is expected that there will be a surge in the demand of these carbon credits and hence the price of one carbon credit will also increase. Thus, if the telecom operator companies act quickly to reduce their carbon emissions, they can accumulate carbon credits now and reap the benefits in the future. Hence, implementing Green solutions in their networks, will not only benefit the network operators to reduce their OPEX and CAPEX but also act as means to generate more revenue. Conclusion As the World moves towards Greener solutions, it has not only reduced the carbon emissions but has also helped to provide ample new opportunities for business. As we have seen in this paper, network operators have ample amount of opportunities to reduce their OPEX and CAPEX. By using energy efficient products and features, optimizing networks, smart innovative energy-saving solutions and powering Telecommunication systems with renewable sources of energy, the Telecommunication network operators can reduce their power consumption by 50% 70%. This can in turn lead to proportional reduction in the energy costs. As the energy costs make up for around 50% of the OPEX, the operators can drastically reduce their operating expenditure and improve the bottom line of their companies. This also gives operators a chance to venture into new markets, provide better services for their customer and also come up with innovative cost-effective schemes to retain their customers. Adopting green methods, also leads to reduction in the CAPEX as has been discussed in the above topics. Though, the initial investment in Eco-friendly solutions is higher, the reduction in energy consumption and costs brings the Total Cost of Ownership (TCO) much less than in conventional networks. With tremendous potential for curbing CO2 emissions, Telecommunication operators can also generate a lot of revenue by using their Carbon Credits. In India, Bharti Airtel is one of the operators, who has entered into the carbon credit venture with partner ACME Telepower. This partnership has brought about $30- $40 million revenue to the both companies involved. Hence, Carbon trade is also another major incentive for the operator s to adopt environment friendly solutions within their networks.

Role of Women :: essays research papers

Different authors have different approaches to the same issue. In this paper I will contrast and compare how the authors Alexis De Tocqueville, Holly Dover, and Christina Hoff Sommers, tackle the myth of the role of women in society and what the role of women should be according to them. De Tocqueville   Ã‚  Ã‚  Ã‚  Ã‚  De Tocqueville was a French aristocrat who came to America to study the American penal system. Coming from a European society he was struck by the way Americans understood the equality of the sexes. He published his book Democracy in America in 1835, which is from where our excerpt came from.   Ã‚  Ã‚  Ã‚  Ã‚  De Tocqueville seems very impressed with the fact that American women are capable of performing the same duties as men but do not choose to because they rather maintain their natural place in society. American women are just as capable as men in understanding politics and other important affairs, but choose not to occupy themselves with such matter, so they spend more time in preserving their natural beauty and their natural place in society without being forced to. He also seems pleased by the fact that the women take pride in â€Å"bending themselves to the yoke†. He seems to be very content with American men as well who, unlike European men, do not flatter their women constantly and boast themselves to be women’s slaves but instead, show the appreciation of their women through their actions. European men on the other hand are all talk. De Tocquville says in his closing argument that even though American women are extremely dependent on the men, he has never seen any women occupy a loftier position. He attributes America’s superiority to the superiority of her women. Another way of looking at the roles we assume in society is that they are â€Å"socially constructed†. Holly Devor brings this view to our attention in an essay. Being a professor of sociology at the University of Victoria in British Columbia, she is an expert in the field. She uses a more scientific approach, as compared to De Tocquville, to the argument about the role of men and women in society. She believes that we learn how to live our lives according to our gender at a very young age. According to research, by the age of five years old, children may be able to accurately recognize their own gender and the genders of the people around them; however, they will often do that on the basis of role information, such as hairstyle and clothing, rather than physical attributes such as genitals.
