Materials in Construction - Essay Example This has two components namely: direct and indirect. Direct energy is the energy used to transport building products to the site, and then to construct the building while indirect energy is the energy used to acquire, process, and manufacture the building materials, including any transportation related to these activities. Different materials have different embodied energy. It is measured as a quantity of non-renewable energy per unit of building material, component or system. It may be expressed as megaJoules (MJ) or gigaJoules (GJ) per unit of weight (kg or tonne) or area (square metre). Some embodied energy of common materials are presented in the table below. Embodied energy in construction has important connection to environment since CO2 emissions are highly correlated with the energy consumption. Literatures show that on average, 0.098 tonnes of CO2 are produced per gigajoule of embodied energy. Therefore, the higher the embodied energy of a specific construction material the higher its environmental effects. The external envelope is the primary and critical component of a building that serves as insulator and a protective physical covering for the occupants. The envelope consists of the roof, walls, windows, and the doors. Design of a building’s external covering is based upon several performance objectives such as: structural integrity, moisture control, temperature control, and control of air pressure boundaries. Common measures of the effectiveness of a building envelope include physical protection from weather and climate (comfort), indoor air quality (hygiene and public health), durability and energy efficiency. In order to achieve these objectives, all building enclosure systems must include a solid structure, a drainage plane, an air barrier, a thermal barrier, and may include a vapor barrier. Moisture control is essential in cold climates. Since the building enclosure is

History of Biligual Education Essay Example for Free

History of Biligual Education Essay My project was to go and find out about bilingual education’s history, process, and the experts in the field of bilingual education. Bilingualism is the ability to speak two languages fluently. Bilingualists study Bilingualism and bilingual education, which is teaching all subjects in school through two different languages. Bilingual Education was first adopted in Ohio in 1839, due to the increase of German-Americans (Rethinking). By the end of the 19th century, many states had adopted bilingual education laws to meet the demands of new immigrants due to industrialization. When World War I came many Americans changed their views of bilingual education, due to the fear of German-Americans and the government’s new Americanization policies, including English-only instruction. It wasn’t until the Civil Rights Movement Era and the Bilingual Education Act of 1968, when bilingual education was reintroduced into the United States. â€Å"The courts decision in the landmark Lau v. Nichols case required schools to take affirmative steps to overcome language barriers impeding childrens access to the curriculum. Congress immediately endorsed this principle in the Equal Educational Opportunity Act of 1974.†(Rethinking). In California, bilingual education was banned until 1967. In 1967, Governor Ronald Reagan signed legislation (SB 53) that authorized bilingual education, before the Bilingual Education Act of 1968. A blow for bilingual education came in 2002, when President George Bush’s No Child Left Behind Act got rid of the Bilingual E ducation Act of 1968, changing the way people look at bilingual education. In 1998 California, under Ron Unz’s Proposition 227, reverted Ronald Reagan’s SB 53. This Proposition later confirms Bush’s No Child Left Behind Act and the country’s renewed interest in English only instruction, due to the Iraq War. Many critics of bilingual education believe that bilingual education is failed, but proponents of bilingual education feel bilingual education is a better option than English-only instruction. Critics of bilingual education believe that children who receive bilingual education will not be able to help students learn English as well as English-only students. One of the critics of bilingual education, Rosalie Pedalino Porter of the Institute for Research in English Acquisition and Development (READ), believes that â€Å"the expectations for bilingual schooling were threefold: better and more rapid learning of English; better mastery of school subjects; and higher self-esteem among students, which could lead to higher academic achievement and fewer school dropouts. Unfortunately, none of these goals was achievedThe goal [of English immersion] is threefold: early literacy development in English, subject matter instruction in English with a special curriculum, and early inclusion of LEP students in mainstream classrooms for maximum exposure to native speakers of English and for greater integration of diverse student populations(Porter). However, â€Å"controlled studies consistently show that children in such properly organized bilingual classes acquire at least as much English as those in all-English classes and usually acquire more†(Krasen). Another proponent of bilingual education, Jay Greene provided research that â€Å"the use of the native language in instructing limited English proficient children has moderate beneficial effect s and that efforts to eliminate the use of the native language in instruction harm children by denying them access to beneficial approaches†(Greene). In addition to the belief that children who receive bilingual education will not be able to help students learn English as well as English-only students, critics of bilingual education believe that the passage of Proposition 227, caused test scores to increase. Proponents of 227 from the READ Institute argue that, the test scores from 1998-2000, show that minority English language learning students in California have done better on the SAT 9 test than those in bilingual education had done before (Mora). Kenji Hakuta, shows in his article, Points on SAT-9 Performance and Proposition 227, â€Å"test scores rose in districts in California that kept bilingual education, as well as in districts that never had bilingual education† (Hakuta). In addition, â€Å" Scores increase about 1.5 to 2 points per year after a new test is introduced. Thus, test score inflation accounts for about half of the increase in grades two and three in the SAT9 reading test since 1998, and all of the inc rease in grades four through seven SAT9 reading scores in California have actually declined slightly in grades eight through eleven†(Linn et. al). Research done by these bilingualists show that Proposition 227 has not increased the minority English language-learning students in California’s English skills. Critics of bilingual education believe that poorly trained teachers and complicated bilingual education structures cause more confusion than English-only programs. Susan Headden, writing in U.S. News World Report, comments, â€Å"Poorly trained teachers further complicate the picture. . . . The paucity of qualified candidates has forced desperate superintendents to waive some credentialing requirements and recruit instructors from abroad. The result is teachers who themselves struggle with English† Advocates cite that just because bilingual education needs improvement doesn’t mean it should be eliminated. Critics of bilingual education look at the success of Canada’s French immersion policy in schools. In kindergarten and first grade native-English speakers are taught entirely in French. Then gradually, English is introduced and by the end of elementary school, most students become fluent in French and English. However, more impressive is the bilingual education of European countries. Since there are eleven different official languages of the European Union, students are taught multiple languages .The study of first foreign language begins in first year of primary school, then an additional language is added in the second year of secondary school and the fourth year of secondary school. By the time students exit college with a Baccalaureate degree, they will know at least four languages. From, my research I was able to find proponents and critics of bilingual education. I noticed that there were many more proponents of bilingual education, among them are Kenji Hakuta of Stanfor d University, Colin Baker of the University of Wales, Stephen Krashen of the University of Southern California, Wayne P. Thomas and Virginia Collier at George Mason University, and Jim Cummins of the University of Toronto. Critics of bilingual education include politicians, George Bush, Susan Headden, and Rosalie Pedalino Porter. Perhaps we should be looking to other nations to solve our educational issues, as neither English-only nor bilingual education seems to work.

Comparative Coverage of Women Issues in Elite Press

Comparative Coverage of Women Issues in Elite Press Comparative Coverage of women Issues in Elite Press of Pakistan, India Bangladesh Key Words: Mass Media, Print Media, portrayal, Women, Issues, treatment, Pakistan, India, Bangladesh, Elite Press, Visual, Textual, Analysis Introduction We are living in the twenty-first century and it is a heart-throbbing fact that still most of the sections of our society do not realize the importance of women in the socio-economic fabric. It would be deplorable if the status and the role of women were not appropriately perceived, since women are a part of society and share work and responsibility. Therefore, it is indispensable to upgrade the depiction of women and to strengthen the informational role of the media. Butt Mourion (1996) says that media are one of the modern ways to maintain and promote ideology and to relate it to the national needs, but also adds that to do this promotion, a grand number of projects and actions are required constantly by the state and the people as well. Media is playing vital role in dissemination of information, shaping and reshaping the perception and public views. The mass media have an essential role reporting wrong doing following up remedial action, mobilizing public opinion, brining about social change and highlighting positive developments. In fact, media and women issues coverage important topic in every era. The study is focused to analyze the visual and textual presentation of the women related news regarding social, economical and political issues in the elite press of major countries of South Asia which includes Pakistan, India and Bangladesh. The study is important because before partition of the subcontinent these three countries enjoyed the status of united India. So these countries are having similar roots sharing common norms, values and society. In this study researcher is going to analyze the women issues in major newspapers of Pakistan, India and Bangladesh which include topics of news stories, tone of covered news, location of news stories in newspaper and amount of space is given to news. Through these aspects researcher will analyze whether the print media portrayal women image positive, negative or neutrally Media The life styles, socialization patterns, participation levels, cultural boundaries, political maneuverings, religious manifestations, educational standards, social hierarchy, and images of society these all sectors that influence by the media content (Sharma, 2005). The media is a vehicle used to inform as well as entertain the public. The media is a carrier of information, ideas, thoughts and opinions. It is a powerful force in influencing people perceptions on a variety of issues. Print media is oldest medium that educate, inform and entertain the people. In modern society is mass media responsible for construction and consumption of social knowledge and their meanings that use people make a sense abut world and act as social reality accordingly. Print media plays an important role in influencing public opinions and setting agenda for what is constructed as news. The print media which include newspapers, periodicals, newsletters and other channels are relied upon by the people as c redible source of information, education and entertainment. The print media are known for fearless criticism and service. The print media or newspaper is consists of current affairs news, articles, features, advertising. Newspaper normally publishes stories on local, national and international politics issues, entertainment, society, business, technology, education, agriculture, sports etc. Also editorials, columns and letter to editors on current issues publish in newspaper on particular pages. Print media started in these three countries with the Independence Day but some news papers were running before the partition such as Dawn, Nawa I Waqt and Jang (Pakistan) The Hindustan Times, The Times of India and Dainik Jagran (India) and The Daily Star. Women Women are an integral part of our society, and cannot be ignored due to less power and authority. They are created using the need for men and men, presenting them with a companion in the course of life. Although women are significantly in all areas of life, the long list of people in the treatment seems to be never ending. There is no denying the fact that in todays society, where women are still mostly male, is dominated by pine from the inferior place to put side-by-side with men because of social and stick are typically held social values. In fact, womens position in any of the countries varies according to the categories, regions, and rural and urban distribution unequal socio-economic development and the impact of tribal, feudal, and capitalist social formations on womens lives. Today Pakistani women have a better position than most of other Muslim women. However, on an average, the womens situation vis-Ã  -vis men are one of systemicgender subordination. However, awareness among Pakistani women to expand the educational opportunities increased from past few years. According to the United Nations development index, Pakistani women are better in gender equality, as women in India and Bangladesh. However women condition in India is worst as compared to other development countries majority of Indian population consist of female. Today average female life expectancy today in India in contrast to many others countries is below the standard line (Nautiyal Dabral, 2012). Majority of women deprived the basic facility of life such as food, health and education in India and also socially women life in India very terrible. Indian society gives the more dominancy and importance to male in any walk of life as well as male social development. The status of women in Bangladesh is defined as an ongoing gender battle, the prevailing political tide, who favors restricting the rights of women in the Islamic patriarchal patterns, and activism. The Bangladesh socio-cultural environment provides comprehensive gender inequity so that girls and women face many obstacles in their development. The girls are often considered the financial burden on the family, and since birth, they receive less investment in health, health care and education (UNICEF, 2007). In Bangladesh, women have made huge gains since the country gained independence in 1971. In the past four decades have seen increased political influence for women, better employment prospects, improving training and new laws protect their rights. Many of the women working in the States and other key positions but in issues like family violence, acid burning and rape are still persist. Media and Women The media portrayal both positive as well as negative issues of women as well as a powerful mechanism. Although the media has played an important role in highlighting womens issues, it has also had negative impact, in terms of perpetrating violence against women through pornography and images of women as a female body that can be bought and sold. (Sharma, 2005) the trend is increasing in media to represent women as victims are more alarming. Media reflects in its content the pattern of value in any society. According to (Sharma, 2005) for the purpose of promoting and disseminating information media play an important role and also it is main role in development of women in social and economic sectors. The way subjects dealing with women are treated indicated to a great extent the prevailing attitude of the society towards women. Everywhere the potential exists for the media to make a far greater contribution to the advancement of women. More women are involved in careers in the commun ications sector, but few have attained positions at the decision-making level or serve on governing boards and bodies that influence media policy. Womens appearance in sensational news stories such as glamour, sex, domestic violence and other forms of violence are still prominent (Nautiyal Dabral, 2012). Portrayal of women in the media is mostly unfair and imbalanced. They are under-represented which falsely implies that men are the cultural standard and women’s role in the social life is unimportant or negligible. Women are portrayed stereotypically that reflect and sustain socially endorsed views of gender. Their presentation in the media does not conform to their real role in the society. According to Patel (1995) the mainstream media like print more highlight the women physical body image side by side along stereotyped sexist images and the back page pin ups. She observed that one of the reasons for projection of patriarchal image of the society is disproportionate number of men in the key positions in media. As to the qualitative aspect of portrayal of women in the media that they are generally portrayed as unthinking, dependent and submissive beings with reproduction as their fundamental role. Women are either portrayed as ideal or deviant. Their real life feelings and b ehaviors are rarely depicted on screen. She is shown more in fantasy roles than her real life. Common woman in the society finds it hard to relate herself to the depiction of females in the media. The negative portrayal of women in the media not only does not correspond with the reality but also leads to promote unhealthy and harmful traits among the public. Statement of the Problem Press is prognostic the women in a totally immoral way according to society values in news. While these types of news became the sources of spreading obscenity, western style, trends and personalities are being highlighted quite indecently. The news about scandals, rapes, pregnancy, fashion shows, show-biz and private matters of wife and husband are being over played instead of the women development and social progress. The photographs related to these news are nude, and below the standards of morality. Newspapers are more focusing the sexual crimes are being highlighted in which women are badly humiliated. In fact, film stars and celebrities’ news are being accommodated as commodities. Hypothesis Whether or not Pakistani, Indian and Bangladesh press portray women as commodities? Whether or not Pakistani, Indian and Bangladesh press treating women issues in real sense and focusing social development? Whether or not Pakistani, Indian and Bangladesh press portray women issues as sensational news? Objectives of the Study The objectives of this research, which can be specified on the spot to find the answer the following questions as below: To analyze representation of women in selected newspaper of Pakistan, India and Bangladesh. To examine the quality of the women related news published in selected newspapers. To find out the selected issues related to women that are discussed subject matter or not. To understand whether or not women related news are treated as traditional approach in selected newspapers. To check the nature/style of news related to women issues in selected newspapers. To understand print media reporting patterns are favorable/ unfavorable towards women Printmediaportraystereotypicalimageof womeninnewsstories Nautiyal Dabral (2012) The journals are mostly qualified for modern society and could be said to be positively harmful to the development of women as conscious individuals aware of themselves and aware of the society around them. If a woman wins a beauty contest, magazines or newspapers in particular give much importance to the news and even take her photographs on cover page but, at the same time if a woman gets the Nobel Prize she gets limited coverage. Here the difference of judgment in womens issues is quite marked in our media. Similarly the daily newspapers rarely put womens news and their development. Rather they prefer reporting on rape, atrocities, crime, sexual harassment and abuse of women prominently in their columns.

David Livingstone :: History

David Livingstone David Livingstone was one of Africa’s most important explorer. He lived from 1813 to 1873. He was originally a Scottish doctor and missionary. Livingstone was born on March 19, 1813, in Blantyre, Scotland. In 1823 he began to work in a cotton-textile factory. While studying medicine in Glasgow, he also attended classes in theology, and in 1838 he offered his services to the London Missionary Society. After completing hid medical course in 1840, Livingstone was later sent as a medical missionary to South Africa. In 1841 he reached Kuruman, a settlement founded in Bechuanaland, now Botswana, by the Scottish missionary Robert Moffat. Even though the Boers, the white settler, mostly of white background were extremely hostile to him, Livingstone kept trying to make his way northward. He married Mary Moffat, daughter of Robert, in 1845. Together, the Livingstones traveled into regions where no other European had ever been to. After crossing the Kalahari Desert in 1849, he discovered Lake Ngami. In 1851, accompanied by his wife and children, he discovered the Zambezi River. On another expedition while looking for a route to the interior from the east or west coast, he traveled north from Cape Town to the Zambezi, and then west to Luanda on the Atlantic coast. Then, retracing his journey to the Zambezi, Livingstone followed the river to its mouth in the Indian Ocean, in this way discovering the great Victoria Falls in Zambezi. After Livingstone's explorations, a revision of all the contemporary maps took place. He returned in 1856 to Great Britainm, where he was already acknowledged as a great explorer. He wrote a book called Missionary Travels and Researches in South Africa which made him famous. He resigned from the missionary society, and in 1858 the British government appointed him British consul at Quelimane, what is now in Mozambique, for the east coast of Africa and commander of an expedition to explore east and central Africa. In 1859 he explored the Rovuma River and discovered Lake Chilwa. During his exploration of the country around Lake Nyasa, Livingstone became greatly concerned over the depredations on the indigenous Africans by Arab and Portuguese slave traders. In 1865, on a visit to England, he wrote Narrative of an Expedition to the Zambezi and Its Tributaries, including a condemnation of slave traders and an exposition of the commercial possibilities of the region, now mostly part of Malawi and Mozambique.

The Electronic Cigarette

Electronic cigarettes, or e-cigarettes, have become increasingly popular in recent years. Regular cigarette smoking has been on the decline due to many factors including price, health risks, and the fact that most public places no longer allow indoor smoking; making it an inconvenience to step outside and light one up. The convenience, affordability, and health benefits are just a number of reasons the electronic cigarette is rising in popularity. A comparison between e-cigarettes and regular cigarettes show a number of similarities and differences. E-cigarettes offer the same amount of nicotine regular cigarettes do, thus satisfying a smokers nicotine craving that is attributed with cigarette smoking. E-cigarettes just about look, feel, and weigh about as much as a real cigarette, so puffing on one won't feel foreign to the seasoned smoker. Smoking regularly can get pretty expensive and buying the e-cigarette start up kit can be just as expensive too. As a smoker myself, I have noticed a number of differences between cigarettes and e-cigarettes. The taste of a regular cigarette to me is much more satisfying than that of an e-cigarette. E-cigarettes lack the authentic tobacco taste that cigarettes have and this leads to a less pleasing smoking experience. Cigarette smoke is full of harmful toxins, whereas e-cigarettes have about 1,000 times less toxins and there is no smoke, only water vapor. This leads to why most people who aren't ready to fully quit smoking, to start smoking e-cigarettes. Cigarette smoking is also very expensive, whereas e-cigarettes require quite a heavy initial investment at first, around $100 for the start up kit, they pay for themselves in the long run and end up saving you money over time.

Description Of Truk Island Essays - Chuuk Lagoon, Chuuk State

Description Of Truk Island Essays - Chuuk Lagoon, Chuuk State Description Of Truk Island The island of Truk was 800 square miles of sheltered lagoons and strong defensive capabilities. (1) In 1944 the island became vulnerable to allied attacks.(2) All of the warships were subsequently moved away from the island leaving all the forces on the island without warship protection. Truk was still considered one of Japans greatest naval bases. Vice Adm. Chuichi Hara was in command of the forces on the island. At this point in the war the allied forces were just moping up the Japanese as they proceeded to mainland Japan. There was no point in an amphibious assault on an island that had no military significance. Especially when you could just bomb the island form afar. The allied forces were not out to crush every Japanese stronghold. They were making the move towards Japan. It was not necessary to stop at every island and waste lives. Truk was to be neutralized. Carrier aircraft from task force 58 attacked Truk. And shot down everything that was thrown at them. And when they had nothing left to throw at them it was a duck shoot. They pounded the island. 31 ships were sunk(3). 270 aircraft destroyed(4). The forces on the island were reduced to nothing in a few short months. Of the forces that were left instead of fighting the allies they were fighting starvation and disease. 2,000 died of starvation(5) Bibliography Work Cited Hagen, Jerome, War in the Pacific (Ohio: Book Masters, Inc. 1988) 270 Hagen, Jerome, War in the Pacific (Ohio: Book Masters, Inc. 1988) 270 Hagen, Jerome, War in the Pacific (Ohio: Book Masters, Inc. 1988) 270 Hagen, Jerome, War in the Pacific (Ohio: Book Masters, Inc. 1988) 270 Hagen, Jerome, War in the Pacific (Ohio: Book Masters, Inc. 1988) 271
