Liquid Crystal Display Essay

A thin, flat electronic visual display that uses the light modulating properties of liquid crystals is known as a liquid crystal display. Direct light is not emitted by LCDs. Displaced cathode ray tube (CRT) displays of LCDs are used in most applications. Two sheets of polarizing material, are used in LCD displays, with a liquid crystal solution between them. The crystals align as a result of an electric current, so that light cannot pass through them. Each crystal, therefore, is like a shutter, either blocking the light or allowing light to pass through. Some of the technologies behind liquid crystal display are as follows Illumination-A cold cathode fluorescent lamp that is situated behind the LCD panel is used as an external lighting mechanism as LCD panels produce no light of their own. The conventional backlit LCDs are now being widely replaced by two types of LED backlit LCD displays. Active Matrix-This design depends on the usage of thin film transistors (TFT) — basically, tiny switching transistors and capacitors. One of the most important technologies behind liquid crystal display. These are arranged in a matrix on a glass substrate. They are required to switch the LCD’s pixels on and off rapidly. In LCDs, each colour pixel is created by three sub-pixels with red, green and blue colour filters. Twisted Neman tics-To allow light to pass through, twisted nematic displays containing liquid crystal elements are used, these twist and untwist at varying degrees to allow light to pass though . Any grey level or transmission can be achieved by properly adjusting the level of the voltage. Advanced fringe field switching (AFFS)-This technology provides superior performance and colour gamut with high luminosity. It helps in maintaining a wider viewing angle for a professional display and also minimizing colour distortion. Enhancement of the white/grey reproduction is achieved by optimizing the white gamut which also corrects the colour shift and deviation caused by light leakage. Vertical alignment (VA)-In this technology the need for extra transistors is removed because the liquid crystal material naturally exists in a vertical state. When no voltage is applied a black display is created and a white display is created when voltage is applied. This is one of the most widely used technologies behind liquid crystal display Bluephase Mode-It is used to obtain a better display of moving images; it also helps in improving the temporal response of liquid crystal displays. This technology removes the usage of expensive colour filters also short switching times can be achieved so realization of time sequential colour coding can be done Quality Control-There maybe occurrence of defective transistors in LCD panels which cause permanently lit or unlit pixels which are known as stuck pixels or dead pixels respectively. The presence of few defective transistors does not hamper the stability of the LCD panels. However the location of the defective pixels is important . it may be rendered useless if the defective pixels are clustered or are in the centre of the viewing area . also uneven patches may occur which is termed as clauding.

Bridging the Gender Gap in Oil and Gas

1.0 Introduction For many countries, the extractive industry plays a major role as an economic driver, creating jobs, revenue and opportunities for development and growth. There are also social, economic and environmental risks associated with these industries which affect men and women differently. Research by the World Bank (2009) has indicated that men have the most access to the benefits of these industries, whilst women are more likely to suffer the consequences of the social and environmental harms associated therewith. The different experiences of men and women in these industries significantly affect the ability of women to contribute to active growth and development in their respective economies. The gender gap in the oil and gas industry exists in two separate forms, the first being the top-end employment discrimination where there is a lack of females at the higher end of the employment spectrum seeing very low numbers of female engineers, and science and technology employees (European Com mission, 2009). On the one hand this problem is a reflection of the imbalance of opportunities for adequate education, and on the other is what is referred to as the ‘leaky pipeline’ conundrum which describes the phenomenon of disproportionate numbers of women leaving these professions in each consecutive career stage in this industry. The second form of the gender gap is the very low numbers of female employees at the bottom end of the employment spectrum, that which requires lower education standards, but which may be more physically intensive. The World Bank reports (2009) that in most companies there is a female workforce of less than 10%, as these types of jobs are generally considered to be a ‘man’s job’. This is so because of the inherent physicality required in these work environments and the exposure to chemicals which presents a problem for female employees that are pregnant, meaning more time away from work and the inability to work if pre gnant. This research will consider the existence of the gender gap, the justifications therefore, the effects of the gap and recommendations for closing this gap in the industry in terms of ensuring that the opportunities for growth and development, both economic and social are equally accessible in modern oil and gas industry. 1.1 Background to Research 1.2 Significance of Research 1.3 Research Question & Research Objectives1.3.1 Research QuestionWhat is the extent of the gender gap in the oil and gas industry?1.3.2 Research ObjectivesTo determine the causes of the gender gap in the oil and gas industry. To determine the effect of the gender gap in the industry. To determine a succinct set of recommendations for companies in the industry, as well as regulatory authorities in order to close this gap moving towards equal employment opportunities in this industry. 1.4 Proposed Structure 2.0 Methodology The research is primarily a conceptual research dissertation that focuses on an extensive conceptualization, contextualization, evaluation, and analysis of the key issues relating to Corporate Social Responsibility in the oil and gas industry. A conceptual research employs an analytical framework that is based on â€Å"a set of broad theories and ideas that help the researcher to identify accurately the problem(s) they seek to address, frame their research questions appropriately, and locate appropriate literature on the research subject† (Smyth, 2004: 168). In using the conceptual research method, this research combines theoretical and analytical aspects in order to achieve its aims and objectives and provide pertinent answers to the research objectives. In light of the fact that conceptual research requires access to an extensive pool of resources, there is a great reliance on diverse sources of secondary materials for analysis. In this regard, some of the sources of seconda ry data for the research and analysis include electronic databases such as Questia, Jstor, Emerald Insight, and Google Scholar. Of specific interest are journals that focus on gender issues in extractive industries in general as these are analogous with the oil and gas sector, but particularly those that are based on the study and evolution of the gender gap in oil and gas companies, focusing on developing nations and the Gulf countries, as these represent compounded historical gender issues. 2.1 Qualitative Research 2.2 Content Analysis 2.3 Data Collection 2.4 Reliability and Validity of Research 2.5 Research Limitations 3.0 Literature Review 3.1 The Gender Gap in Developing versus Developed Countries3.1.1 Differences in Socio-economic problems3.1.2 The relevance of education in enforcing this gender gapIf one considers the vast differences in education priority placed in Gulf countries by comparison to African oil-economies such as Nigeria, one can see a very different picture of the relevance of education. On the one hand, Gulf countries are more likely to actively discriminate against female executive employees as there is a larger pool of adequately qualified female candidates, where in developing countries there are fewer qualified candidates, because of the lack of priority given to education and particularly education of females.3.1.3 The difference in the nature of the Gender Gap in different socio-economic conditions3.2 Cultural Sensitivities and Pragmatism In certain regions of oil and gas exploration, companies base their hiring discrimination on ‘cultural sensitivities’ where there is a concern for hiring women in higher-paying jobs would cause a backlash against women by their male colleagues (Musvoto, 2001). This has resulted in communities with soaring unemployment rates of up to 87% of women, despite the female demographic representing over half the local population. Particularly in developing countries, there is a trend towards rural-urban migration of the working population which often sees the breadwinner of a family leaving to work in an urban environment which perpetuates this gender gap by enforcing the role of the female as a caregiver rather than a breadwinner. In addition to these cultural sensitivities is a pragmatic approach taken by oil and gas companies which represents the bottom line in the sector in terms of cost implications. There is an argument to be made either way, with diversity goals becoming a secondary concern in favour of productivity and outcome. Male workers often have had greater educational opportunities and therefore less training and education is required, as well as less concern for factors of work-life balance. In the current economic climate, cost effective labour solutions are being of primary importance, particularly considering the growing importance of labour standards and quality of work environments which also present greater cost implications. On the other hand, studies have shown that in employment that is non-physical in nature women perform more productively and effectively, coupled with the barrier to private sector growth and development that employment discrimination breeds, increased female representation in the oil and gas sector may prove to be a more economical labour practice. Unfortunately however, despite evidence of long-term benefits of gender equality in the sector, companies choose short-term benefits which perpetuate and enforce this g ender gap.3.2.1 The broader socio-economic effect of the culturally enforced gender gapA theoretical expose on the broader socio-economic effects of the gender gap, e.g. continued lower education levels of women, perpetuated poverty for single parent households, lack of diversity in the workplace.3.2.2 The benefit of a diverse workplace3.2.3 Increased Issues with Work-Life Balance based on Gender3.3 Leaky Pipeline Anomaly and Evolution of Policy to Mitigate the Gender GapThere are a number of potential explanations for this anomalous situation of women in high end oil and gas jobs, one of which is the role of women in many societies as the primary caregiver of their families (United Nations, 2008). Therefore, as women progress through their careers there is a likelihood of their care responsibilities, as well as job responsibilities increasing proportionately and simultaneously, and as a result they are less able to meet the demands of higher level employment. Whilst certain industr y competitors have been recorded as saying that they attempt to incorporate individual career plans that take account of these increasingly personal responsibilities of employees (Al Tukmachy, 2012), the reality is a labyrinth of professional obstacles described as the ‘glass ceiling’ metaphor where female progression in the industry is limited due to concerns of increased need for consideration of factors of the work-life balance that are less present in their male counterparts (European Commission, 2009). As a result, women are often worked out of these executive and management positions, because companies offer incomprehensive policies that do not consider individual career and family outcomes (European Commission, 2009).3.3.1 Current Changes in Policy Direction to Increase Diversity and Retention of Female Staff – A corporate perspective 3.3.2 International Instruments Mandating Diversity in Oil and Gas MNEs4.0 Discussion 4.1 Analysis of the Gender Gap by Reg ion 4.2 Analysis of the Gender Gap by Employment Level4.2.1 Executive 4.2.2 Managerial 4.2.3 Non-managerial 4.2.4 Labour 4.2.5 Discussion 4.3 Current Examples of Corporate Policy for Non-Discriminatory Work Practices 4.3.1 Strengths 4.3.2 Weakness 4.4 Current Examples of Employment Schemes aimed at Female Inclusion in the Workplace 4.4.1 Strengths 4.4.2 Weaknesses5.0 Conclusion The gender gap in the oil and gas sector is very current and topical debate as gender equality in the workplace is becoming a diversity goal around the world. Careful understanding of the causes and effects thereof are imperative for the management of these companies and the greater macro-economic goals of development and growth. This research therefore aims to contribute to the current understanding of these goals in order to further the studies and make concrete recommendations in order to close this gap and further growth and development in the sector. 5.1 Recommendations 5.2 Conclusion References Al Munajjed, M.

Speed the Light Charity

Chandler Mann Ms. Girkin 8th period Pre-AP English II 4 May 2012 Speed the Light Speed the Light is a student initiated ministry where students of the Assemblies of God denomination pledge a certain amount of money towards missionary efforts. Ass the year rolls along, the students will pay off the pledges they set. The money the students raise goes to missionaries across the globe. With the different needs and requirements of being a missionary come the expenses (â€Å"What is Speed†).Speed the Light was started in 1944 by a minister named Ralph Harris to let students that didn’t feel like being missionaries help out the efforts to spread the gospel (Speed the Light). Since then speed the Light has grown to be one of the largest church founded charity groups in the world. Although Speed the Light has become so large, it was once an emergency program for war time missionaries. Soon after the organization was founded, World War II was coming to a close. Harris thought tha t that would be a hinge to swing on. Speed the Light took off and the war time missionaries took advantage of the war’s destruction (McGee 218).The influence of the organization sky-rocketed within five years of the war’s end, and Speed the Light’s influence started to grow tremendously. Harris became the godfather of the effort and was commonly seen to be encouraging the late Billy Graham. Billy spread the word of god so much that today he is known as the door to door prophet. Today his efforts have helped not only the vision of Speed the Light, but the enthusiasm of the young teens of the Assemblies of God. Because of these efforts today Speed the Light is more active than ever. In 2009 two siblings of Berryville high school raised a combined total of almost 3,000 dollars.Morgan and Eric Barr spent one whole year alone raising money for Speed the Light. Although they knew that their 1,000 dollar pledges were a massive goal, they did not slack off. Their effort s went towards missionaries in third world countries that haven’t heard the gospel. I also participated as well, raising a hard earned 521 dollars. I can attest to the fact that I have never felt that my money could’ve gone to a better cause. Speed the light is a very renowned organization that has helped missionaries spread the word of god for more than 65 years.Over 7. 6 million people have come to have a lasting relationship with Christ since its start in 1944. Speed the Light is an excellent contributor to the spread of Christianity. I hope they continue to make a difference in the decades to come. They are a shining start in our world of pain and hopelessness. Works Cited People of the Spirit. McGee, Gary B. Springfield, MO. Gospel Publishing House, 2004. Print. About Speed the Light.

History J3 - Essay Example uiano gives a vivid description of the Middle Passage which demonstrates the terror of the prisoners, the abject conditions on board and the attitude of the slavers to their cargo. The captured African slaves are absolutely terrified on their passage. The main reason for this fear is the ignorance of the Africans, as this is their first encounter with Europeans. Equiano’s horror is â€Å"heightened by my ignorance of what I was to undergo† (Equiano, 1789).The fair complexion, long hair and alien language of the white men makes Equiano believe that they are â€Å"bad spirits, and that they were going to kill me† (Equiano, 1789). The large copper furnace and the dejected, fettered prisoners reinforce his fear of being sacrificed. Another factor which contributes to Equiano’s fear is the water: â€Å"not being used to the water, I naturally feared that element the first time I saw it† (Equiano, 1789). Most of the captured slaves are from interior Africa and have never seen the sea. The ship and its navigation seem magical to the Africans. The conditions on board the slave ship are extremely miserable. The slaves are confined to the unventilated hold, where they are chained and packed tightly together. The initial cargo of slaves is supplemented by the additional slaves taken on at sea. This makes the hold â€Å"so crowded that each had scarcely room to turn himself† (Equiano, 1789). Equiano paints â€Å"a scene of horror almost inconceivable†: the heat, the toxic miasma of perspiration, the suffocating atmosphere, the increasing irritation of the chains, the groans of the dying, the shrieks of the women, the stench of humanity and the tubs of human excreta â€Å"into which the children often fell, and were almost suffocated†   (Equiano, 1789). The stink of the holds is beyond tolerance.The pestilential air makes the slaves ill and even causes fatalities. The rations are insufficient to satisfy the slaves’ appetite. It is a mark of the slavers’ spite that they

Evaluate the potential effectiveness of ECB's monetary policy decision on the recent quantitative easing programme within the Rurozone economy - Essay Example le tend to borrow less thus decreasing consumption of goods and services in the market as the income in household decreases, this reduces the rate of demand of goods and services making unemployment a major issue as people are retrenched and companies do not employ people (Tenreyro, 2008). This in turn affects the GDP of the country negatively. This paper focuses on the Eurozone and the effects of the Quantitative Easing policy introduced by the European Central Bank. The Eurozone is a term used to refer to all the countries that use the Euro as their means of trade within Europe. It compromises of 17 countries which are Germany, Austria, France, Belgium, Finland, Spain, Slovenia, Portugal, Slovakia, Italy, Malta, Cyprus, Netherlands, Luxembourg, Estonia, Greece and Ireland (Gunyà ©, 2004), each with very different economies. Some are developed while others are struggling to find their place in the market making it very difficult to have a one size policy that’s fits all. Some countries like Germany do have a stronger economy (Anderson, 2012) compared to others like Greece that have a developing or not very well established economy. These countries within the Eurozone like all other countries have their central bank named the European Central bank which was established in 1998 to regulate prices of commodities espe cially equities through making monetary policies for countries within the Eurozone (Dominguez, 2006). The first monetary policy effected by the Euro zone in 2008 (Erà §etin, 2014) leading to a euro crisis as the ECB increased the rates of borrowing making achieving loans for financiers of firms or clients very difficult (Ciro, 2013). This lead to fewer consumption of goods and services by consumers that affected the demand curve as consumption reduced which eventually lead to inflation. This ended up affecting the rate of the currency the Euro as domestically produced goods became more expensive than the imports also affecting inflation, unemployment

Assessment alludes to the assessment of restorative records to determine the immunization rate for a characterized assembly of patients and also to give focused on conclusion for development. This step is crucial in light of the fact that numerous studies have recorded that most social insurance suppliers, while strong of immunizations, dont have a faultless recognition of their own practices immunization rates. Pediatricians in these studies incredibly overestimated the extent of completely vaccinated youngsters in their practices. Evaluation increments attentiveness to a suppliers genuine situation and gives a premise for ensuing activities by supplier staff. Feedback is the methodology of educating immunization suppliers about their execution in conveying one or more immunizations to a characterized customer populace. Appraisal together with feedback makes the mindfulness important for conduct change. Feedback for the most part comprises of the immunization program delegate meeting with fitting supplier staff and talking about the effects of the appraisal to figure out the following steps to be taken. Nobody thing will be adequate for each supplier, and a solitary supplier may require diverse sorts of cause at distinctive phases of advancement. Things like little tokens of thankfulness and giving asset materials at gatherings have helped suppliers approach their assignment absolutely and make an environment of cooperation, yet more term objectives must be acknowledged also.

Effects Of Increased Wait-Time On The Quantity Of Attempted Responses Essay

Effects Of Increased Wait-Time On The Quantity Of Attempted Responses And Correct Responses From Elementary ELL Students To Questions In A Classroom - Essay Example It gives the educator, as a scholarly practitioner, the opportunity to examine relevant issues in his or her own classroom or school which may complicate, compromise, or complement the learning process—and to find meaningful, practical, research-based answers. In Action Research, teachers are empowered to design a research-based plan, identify learning issues or problems, review relevant literature that examines identified problems, implement specific, research-based strategies, and discover convincing evidence that supports or contravenes their teaching strategies. The most exciting part of Action Research is the teacher can often observe student improvement during the project and can demonstrate, in a quantitative manner, the improvement of student learning. Sagor notes, â€Å"Seeing students grow is probably the greatest joy educators can experience† (2002, p. 5).... I chose this research topic because I became quite interested in the positive effects of â€Å"wait time† when the concept was first introduced early in this program. Through self-examination of my own teaching behavior and practices, I came to realize that I was not allowing sufficient time for all students to answer questions. I began to wait longer for answers and I noticed a definite improvement in the number and in the quality of answers provided by my students. I extended my "wait -time" in all areas of my classroom, talking circle, small group projects, full class lectures. I notice improvements in the number of answers, participation, and the engagement levels of my students. "Wait time" is one of several tools and techniques learned in this course that I am in the process of implementing in my effort to create a more inclusive and equitable classroom-learning situation. I endeavor to continuously develop as a teacher and I am committed to improving in a manner that in sures each student in my classroom learns and develops to their full potential. I have concluded that implementing "wait time" into my teaching behavior is an important aspect of this development.
