Free Space Optics Essay ABSTRACT: FSO may sound new and experimental but in fact it predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming. FSO has been around for more than a decade, but it is only recently that interest in this technology has started to grow. Free Space Optics (FSO) communications, also called Free Space Photonics (FSP) or Optical Wireless, refers to the transmission of modulated visible or infrared (IR) beams through the atmosphere to obtain optical communications. Like fiber, Free Space Optics (FSO) uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. Free Space Optics (FSO) works on the same basic principle as Infrared television remote controls, wireless keyboards or wireless Palm ® devices. How Free Space Optics (FSO) Works Free Space Optics (FSO) transmits invisible, eye-safe light beams from one telescope to another using low power infrared laser in the terahertz spectrum. The beams of light in Free Space Optics (FSO) systems are transmitted by laser light focused on highly sensitive photon detector receivers. These receivers are telescopic lenses able to collect the photon stream and transmit digital data containing a mix of Internet messages, video images, radio signals or computer files. Commercially available systems offer capacities in the range of 100 Mbps to 2.5 Gbps, and demonstration systems report data rates as high as 160 Gbps. Free Space Optics (FSO) systems can function over distances of several kilometers. As long as there is a clear line of sight between the source and the destination, and enough transmitter power, Free Space Optics (FSO) communication is possible. [pic] Free Space optics (fso) technology Lasers are one of the most significant inventions of the 20th century they can be found in many modern products, from CD players to fiber-optic networks. A laser generates light, either visible or infrared, through a process known as stimulated emission. To understand stimulated emission, understanding two basic concepts is necessary. The first is absorption which occurs when an atom absorbs energy or photons. The second is emission which occurs when an atom emits photons. Emission occurs when an atom is in an excited or high energy state and returns to a stable or ground state – when this occurs naturally it is called spontaneous emission because no outside trigger is required. Stimulated emission occurs when an already excited atom is bombarded by yet another photon causing it to release that photon along with the photon which previously excited it. Photons are particles, or more properly quanta, of light and a light beam is made up of what can be thought of as a stream of photons. [pic] A basic laser uses a mirrored chamber or cavity to reflect light waves so they reinforce each other. An excitable substance – gas, liquid, or solid like the original ruby laser – is contained within the cavity and determines the wavelength of the resulting laser beam. Through a process called pumping, energy is introduced to the cavity exciting the atoms within and causing a population inversion. A population inversion is when there are more excited atoms than grounded atoms which then leads to stimulated emission. The released photons oscillate back and forth between the mirrors of the cavity, building energy and causing other atoms to release more photons. One of the mirrors allows some of the released photons to escape the cavity resulting in a laser beam emitting from one end of the cavity. Terrestrial Laser CommunicatIOns Challenges FogFog substantially attenuates visible radiation, and it has a similar affect on the near-infrared wavelengths that are employed in laser communications. Similar to the case of rain attenuation with RF wireless, fog attenuation is not a â€Å"show-stopper† for optical wireless, because the optical link can be engineered such that, for a large fraction of the time, an acceptable power will be received even in the presence of heavy fog. Laser communication systems can be enhanced to yield even greater availabilities by combining them with RF systems. Physical Obstructions Laser communications systems that employ multiple, spatially diverse transmitters and large receive optics will eliminate interference concerns from objects such as birds. Pointing Stability Pointing stability in commercial laser communications systems is achieved by one of two methods. The simpler, less costly method is to widen the beam divergence so that if either end of the link moves the receiver will still be within the beam. The second method is to employ a beam tracking system. While more costly, such systems allow for a tighter beam to be transmitted allowing for higher security and longer distance transmissions. Scintillation Performance of many laser communications systems is adversely affected by scintillation on bright sunny days. Through a large aperture receiver, widely spaced transmitters, finely tuned receive filtering, and automatic gain control, downtime due to scintillation can be avoided. FSO: Wireless, at the Speed of Light Unlike radio and microwave systems, Free Space Optics (FSO) is an optical technology and no spectrum licensing or frequency coordination with other users is required, interference from or to other systems or equipment is not a concern, and the point-to-point laser signal is extremely difficult to intercept, and therefore secure. Data rates comparable to optical fiber transmission can be carried by Free Space Optics (FSO) systems with very low error rates, while the extremely narrow laser beam widths ensure that there is almost no practical limit to the number of separate Free Space Optics (FSO) links that can be installed in a given location. How Free Space Optics (FSO) can help? FSO’s freedom from licensing and regulation translates into ease, speed and low cost of deployment. Since Free Space Optics (FSO) transceivers can transmit and receive through windows, it is possible to mount Free Space Optics (FSO) systems inside buildings, reducing the need to compete for roof space, simplifying wiring and cabling, and permitting Free Space Optics (FSO) equipment to operate in a very favorable environment. The only essential requirement for Free Space Optics (FSO) or optical wireless transmission is line of sight between the two ends of the link. For Metro Area Network (MAN) providers the last mile or even feet can be the most daunting. Free Space Optics (FSO) networks can close this gap and allow new customer’s access to high-speed MAN’s. Providers also can take advantage of the reduced risk of installing an Free Space Optics (FSO) network which can later be redeployed. The Market. Why FSO? Breaking the Bandwidth Bottleneck Why FSO? The global telecommunications network has seen massive expansion over the last few years. First came the tremendous growth of the optical fiber long-haul, wide-area network (WAN), followed by a more recent emphasis on metropolitan area networks (MANs). Meanwhile, local area networks (LANs) and gigabit ethernet ports are being deployed with a comparable growth rate. In order for this tremendous network capacity to be exploited, and for the users to be able to utilize the broad array of new services becoming available, network designers must provide a flexible and cost-effective means for the users to access the telecommunications network. Presently, however, most local loop network connections are limited to 1.5 Mbps (a T1 line). As a consequence, there is a strong need for a high-bandwidth bridge (the â€Å"last mile† or â€Å"first mile†) between the LANs and the MANs or WANs. A recent New York Times article reported that more than 100 million miles of optical fiber was laid around the world in the last two years, as carriers reacted to the Internet phenomenon and end users’ insatiable demand for bandwidth. The sheer scale of connecting whole communities, cities and regions to that fiber optic cable or â€Å"backbone† is something not many players understood well. Despite the huge investment in trenching and optical cable, most of the fiber remains unlit, 80 to 90% of office, commercial and industrial buildings are not connected to fiber, and transport prices are dropping dramatically. Free Space Optics (FSO) systems represent one of the most promising approaches for addressing the emerging broadband access market and its â€Å"last mile† bottleneck. Free Space Optics (FSO) systems offer many features, principal among them being low start-up and operational costs, rapid deployment, and high fiber-like bandwidths due to the optical nature of the technology. Broadband Bandwidth Alternatives Access technologies in general use today include telco-provisioned copper wire, wireless Internet access, broadband RF/microwave, coaxial cable and direct optical fiber connections (fiber to the building; fiber to the home). Telco/PTT telephone networks are still trapped in the old Time Division Multiplex (TDM) based network infrastructure that rations bandwidth to the customer in increments of 1.5 Mbps (T-1) or 2.024 Mbps (E-1). DSL penetration rates have been throttled by slow deployment and the pricing strategies of the PTTs. Cable modem access has had more success in residential markets, but suffers from security and capacity problems, and is generally conditional on the user subscribing to a package of cable TV channels. Wireless Internet access is still slow, and the tiny screen renders it of little appeal for web browsing. Broadband RF/microwave systems have severe limitations and are losing favor. The radio spectrum is a scarce and expensive licensed commodity, sold or leased to the highest bidder, or on a first-come first-served basis, and all too often, simply unavailable due to congestion. As building owners have realized the value of their roof space, the price of roof rights has risen sharply. Furthermore, radio equipment is not inexpensive, the maximum data rates achievable with RF systems are low compared to optical fiber, and communications channels are insecure and subject to interference from and to other systems (a major constraint on the use of radio systems). Advantages A free space optical (FSO) system offers a flexible networking solution that delivers on the promise of broadband. Only free space optics or Free Space Optics (FSO) provides the essential combination of qualities required to bring the traffic to the optical fiber backbone – virtually unlimited bandwidth, low cost, ease and speed of deployment. Freedom from licensing and regulation translates into ease, speed and low cost of deployment. Since Free Space Optics (FSO) optical wireless transceivers can transmit and receive through windows, it is possible to mount Free Space Optics (FSO) systems inside buildings, reducing the need to compete for roof space, simplifying wiring and cabling, and permitting the equipment to operate in a very favorable environment. The only essential for Free Space Optics (FSO) is line of sight between the two ends of the link. âž ¢ Freedom from licensing and regulation leads to ease, speed and low cost of deployment. âž ¢ Since FSO units can receive and transmit through windows it reduces the need to compete for roof space, simplifying wiring and cabling. âž ¢ Only need is the line of sight between the two ends of the link. âž ¢ Providers take advantage of the reduced risk in installing FSO equipment, which can even be re-deployed. âž ¢ Zero chances of network failure. âž ¢ Virtually unlimited bandwidth. APPLICATIONS âž ¢ Metro network extensions – FSO is used to extend existing metropolitan area fiberings to connect new networks from outside. âž ¢ Last mile access – FSO can be used in high-speed links to connect end users with ISPs. âž ¢ Enterprise connectivity The ease in which FSO can be installed makes them a solution for interconnecting LAN segments, housed in buildings separated by public streets. âž ¢ Fiber backup FSO may be deployed in redundant links to backup fiber in place of a second fiber link. âž ¢ Backhaul – Used to carry cellular telephone traffic from antenna towers back to facilities into the public switched telephone networks. Free Space Optics (FSO) Challenges The advantages of free space optical wireless or Free Space Optics (FSO) do not come without some cost. When light is transmitted through optical fiber, transmission integrity is quite predictable – barring unforeseen events such as backhoes or animal interference. When light is transmitted through the air, as with Free Space Optics (FSO) optical wireless systems, it must contend with a complex and not always quantifiable subject the atmosphere. âž ¢ Fog and free space optics (fso) âž ¢ Physical obstructions and free space optics (fso) âž ¢ Free space optics (fso) pointing stability – building sway, tower movemen t âž ¢ Scintillation and free space optics (fso) âž ¢ Solar interference and free space optics CONCLUSION FSO enables optical transmission of voice video and data through air at very high rates. It has key roles to play as primary access medium and backup technology. Driven by the need for high speed local loop connectivity and the cost and the difficulties of deploying fiber, the interest in FSO has certainly picked up dramatically among service providers worldwide. Instead of fiber coaxial systems, fiber laser systems may turn out to be the best way to deliver high data rates to your home. FSO continues to accelerate the vision of all optical networks cost effectively, reliably and quickly with freedom and flexibility of deployment.

Teacher As A Resource For Students Essay Example for Free

Teacher As A Resource For Students Essay The boy came from The Dominican Republic and did not speak English. This proved to be a problem not just for the young student but his teacher, classmates, and school as well. How would he learn, cope and thrive is his new environment? How would his new surrounding help him adjust? These were the questions that, after a few interventions, were resolved successfully. The intervention began when an aide was appointed to help the boy by serving as his translator. It helped for a while until lessons were starting to get progress. To facilitate learning, I provided supplementary books for the boy’s teacher to equip her in helping the student. Concurrently, the student was given worksheets. With his aide and teacher by his side, the boy started adjusting to his new environment and was learning. He could speak little English and was able to interact with other children. This is a perfect example of what successful teaching is. Successful teaching is a fusion of personal and interpersonal skills and personal and professional commitment (Day, 1999). They act as resources for students. They are the agents of transferring knowledge, skills and values. In this case, employing an aide was a way of capturing and transferring knowledge. Doing one-on-one with the child was also advantageous for it broke the barrier of transmitting information. The aide, in her own way, became an important resource for the student. The teacher also acted as a vital resource. A teacher’s task is to teach but in this case, the teacher also had to learn. She was willing to learn to be able to teach. That is a marking of successful teaching, if a teacher can be a good source for a holistic development of a student. Continued one-on-one guidance with the boy should be encouraged until the boy has completely managed on his own. It is also favorable to continue exposing the boy to his new environment, allowing him to mingle with others and explore. Field trips and activities that foster cooperation may help.

IT Impact on Organizational Performance in Banking

IT Impact on Organizational Performance in Banking Information technology and permeated almost every aspect of business operations and communications technologies. So it is a one of the most exciting research has been focusing on the wide interest in all parts of the world through the decades, but little was devoted to study the impact of information technology to banks in Bahrain. This study examines the impact of information technology on organizational performance in the banking sector during the period from 2005 to 2009. The dependent variable used is return on equity ( ROE) while the independent variables are Hard ware, Soft Ware, System Development Operations, I .T Maintenance, I.T Training , I .T Insurance , I.T Communication, I .T Implementation, I .T Consultancy , I .T Sites and Business Continuity Planning (BCP). Preliminary data collected through in-depth interviews, official documents and surveys of the field through the top 8 banks in Bahrain, this data has been tested by applying different statistical methods and finance. The research results led to the conclusion that information technology has a positive impact on organizational performance in the banking sector. CHAPTER ONE INTRODUCTION As an emerged business trend, the use of information technology (I.T) in the economic organizations are immense and measureless. Systems of organization and functions are now considered effortless and unproblematic because of I.T. information technology passes to be the most important one for each financial institution and the banks, particularly, they are one of the greater investors in I. T, Ahli united bank one of these banks that costs them around $ 13 millions. It is an enormous cost of this technology for local and international market. The existing studies generally have concluded two positive effects concerning the relationship between IT and the financial performance of banks. â€Å"First, it can reduce operational costs of banks (the cost advantage). For example, the Internet helps banks to conduct standardized, low value transactions (e.g. send the bill payments, balance inquiries, account transfers) through the online channel, while focusing its resources on specialized, high value added transactions (eg small business loans, personal trust services, investment banking) through branches. Second, can facilitate transactions between customers within the same network(the network effect). As an example, let us consider the case of automated teller machines (ATMs) by banks. If ATMs are geographically dispersed areas available largely over, the advantage of using an atmosphere will increase as customers can access their accounts from any geographic location they want. This would imply that the value of the ATM network increases with number of locations available in the atmosphere, and the value of the network of the a bank to a customer is determined in part by the final size of the network effect banks network is important in the adoption of the atmosphere. IT has drawn the attention of many researchers, commissioned to study the impact of IT in the functioning of the bank and that is a goal of many organizations. Some researchers have found positive relationships between IT investment and organizational performance and some of it found it negative. Problem Statement IT investments and its impact on the banking industry is a very important point for both banking managers and IT managers to be able to deal with and justify wither increased spending for investment in IT will lead to increase performance of Bank or not. That will put increasing pressure on managers to asses its business value. In this study we will examine the key components of IT investments (Hard ware, Soft Ware, System Development Operations, I .T Maintenance, I.T Training , I .T Insurance , I.T Communication, I .T Implementation, I .T Consultancy , I .T Sites and Business Continuity Planning (BCP) to see if spending in different IT areas as an impacts on bank performances. Significance and Importance The importance of this project lies in its ability to shed a light on the Impact of Information Technology on The Financial Performance of Bank sector in kingdom of Bahrain. Furthermore, this study would encourage other Banks in the area to benefit from Bahraini Banks experience and therefore follow their lead.

Chapter 3 is about the methodology used in this study. Chapter 4 discusses the empirical results and findings of the research. Finally, conclusions and recommendations are made in chapter 5. CHAPTER TWO BACKGROUND CHAPTER TWO BACKGROUND Introduction This chapter will specify some aspects of Bahrains economy and what attracts foreign and local investors to invest their capital in this country; along with some important features and statistical data regarding the banking industry, we will try to know why It is necessary for the management of the organizations to measure and to evaluate the organization performance. Finally, the literature review will discuss a number of some previous studies related to this topic. An Overview of Bahrains Economy The economy of Bahrain is mainly defined by oil production and refining and production, ship repair, iron pelletization, fertilizers, offshore banking, insurance. The country is trying hard to privatize its economy so that it can reduce the dependence on oil production and that prompted the government to develop other industries as well. For example, in 1970, the government established Aluminum Bahrain (ALBA), an aluminum smelting industry which still remains an important industry. In a further effort at diversification, the government has also promoted tourism. The government controls the oil and gas, most heavy industry, and the bulk transport and communications, but has made efforts to privatize the economy, bank transfer, light manufacturing, and trade in private hands.

It was called the fastest growing financial center in the Arab world by the United Nations Economic and Social Commission for Western Asia in January 2006 by the City of London global financial centers index in 2008. In 2004 it signed a free trade an agreement with United States will reduce the trading Which Barriers between the two countries. Bahrain Was the first Arabian Gulf state to sign such a trading mutual agreement with the United States. http://www.mapsofworld.com/country-profile/bahrain1.html https://www.cia.gov Banking Sector in Bahrain Bahrain is the home of more than 400 the authorized financial institutions, what represents a rich mix of international, regional and local names. They cover all the range of financial products, with private concentrations in sure, wholesale banking and funds / asset management. The financial sector is now the major sector of the economy represents more than the 27% of the GDP. The financial sector is also the major employer in Bahrain for more than the 80% of the labor. The sector is regulated and supervised by the Central Bank of Bahrain (CBB) (www.cbb.gov.bh), which since 2002 has functioned as a regulator of the entire financial system. Bahrains banking system consists of both conventional and Islamic banks and is the main component of the financial system, which represent over 85% of total financial assets. The conventional segment includes 19 retail banks, 69 wholesale banks, 2 specialized banks and 36 representative offices of foreign banks. The Islamic segment, offering a series of Sharia Conformity of their products and services include 6 retail and 18 wholesale banks, and the numbers are increasing steadily. The banking sector has played a central role in the development of Bahrain as major financial center in the region. As in December 2006, banking sector assets amounted to over U.S. $ 180 billion, more than twelve times annual gross domestic product. The recent increase in the sector has been supported willingly fortune of the industry of the petroleum and the corresponding increases of liquidity. The banks are playing thus a central role in surplus to reinvest the petroleum incomes as well as complying the opportunities of financing in other segments of the economy. http://www.bahrain1.com/banking.html Performance Measures The performance as declared by Wheelen and hunger (2000) is the final result of an activity and a performance organizacional accumulates turned out final of all the organization process and activities. It is necessary for the management of the organizations to measure and to evaluate the organization performance to utilize organizations resources in better form and to win good organization honorableness. Managers measure and to control organization performance, since conducts to a better management of assets, to a greater capacity to provide value of the client, for improve the measures of organization Knowledge and measure of performance organizacional have an impact on an organization reputation. Literature review Many studies had been done in order provide a clear picture of the financial performance of banks. Gupta, Uma and Collins (1997) investigate the impact of information systems on the efficiency of banks. They were centered in determining the relation among the investments in I.T and bank efficiency; they identified an efficiency measures assembly commonly utilized by the banks and they asked to their respondents to specify if these measures were utilized to evaluate the performance of I.T an investment. They found that the companies ensure that the investments in technology are deliberately and in a significant way aligned with achieving the strategic, tactical one, and the operational goals of the business is probable that to see a narrower link among I.T investments and improvements of productivity of the organization. Thus I.T performs an important and valuable role in helping to reach objectives organizational, to enlarge the productivity to improve service to the client, and to utilize fully existing system. Lunardi, Becker and Macada (2003), they evaluated the strategic impact of IT in Brazilian, American, Argentinean, Uruguayan and Chilean banks as perceived by their executives. In order to externally validate the questionnaire, results were analyzed considering, as isolated samples, (a) Brazil, (b) the United States, (c) Argentina, Uruguay and Chile, and, then, (d) as one group merging all data. The results indicate that (1) Competition, Products and Services, and Borrowers (customers) are the main strategic variables affected by IT; (2) there are no differences between executives of IT and other functional executives regarding their perception of the impacts of IT in strategic variables; and (3) the impact of IT in Competitiveness is significantly related with the impact of IT in Borrowers, Government and Country Requirements, Products and Services, and Cost Structure and Capacity. This study supported banking executives to plan IT strategies, their implementation and to evaluate their use. Another research had been done by Elena Becalli. (2005) Who investigated whether investment in Information Technology (IT) hardware, software and other IT services influences the performance of banks by Using a sample of 737 European banks over the period 1993-2000 . The study found that the impact of different types of IT investment (hardware, software and services) on banks performance is heterogeneous. Investment in IT services from external providers (consulting services, implementation Services, training and education, support services) appears to have a positive influence on accounting profits and profit efficiency, while the acquisition of hardware and software seems to reduce banks performance. Shaukat and Zafarullah. (2009) made a study examined the impact of IT on organizational performance in quantitative terms of Pakistans manufacturing and banking sectors over period of 1994-2005 and come with the following result. I.T changed the character of so much work for the industries and enlarges its performance. This positive impact has shown in indicators of qualitative performance. Significant improvements with regard to the different qualitative variables as customer satisfaction, client/suppliers links, image of the business, employees interest work, shareholders, confidence and among office links/communication they have been observed in both the sectors and banking in Particular . Akram and Allam. (2010), explored the impression on improving the performance of two forms of matrix. The first is matrix of financial performance which comprises Market Value-Added (MVA), Return on Investment (ROI) and Earning per Share (EPR) and the second is matrix of operational performance, which includes the Net Profit Margin (NPM), Operating Return on Assets (ORA) and the profit value of the employee (PE). Utilizing IT by Jordanian banks which measured by testing the level of investment in Hardware, Software, Internet Banking, Phone banking, number of ATMs, use of Cyber branches and Banking via SMS. The results of measurements indicated that there was an impact on the use of MIS in Jordanian banks in the market value added (MVA), Earnings Per Share (EPS), Return on Assets (ROA), Net Profit Margin (NMP). Keramati, Azadeh and Mehran (2009), discussed and tested empirical to moderate environmental effects of dynamism and branch strategy on the impact of the investment and other efficient variables (number of employees and fixed assets) in the branches. The study sample was comprised of 102 branch offices of the bank Parsian and the empirical results, on the base of a model moderate of decline. Concretely, IT investment seems to have a greater positive impact on performance of the banks when there are greater environmental changes and more proactiva strategy branch. According to their conclusions, the banks considering that the investment should evaluate their performance environmental contexts and the strategic orientation. Another investigation has been carried out for Mallick and Shirley (2006). They examined the effects of the information technology (IT) in the banking industry of United States. They found that IT can improve banks performance in two ways: IT can reduce operational cost (cost effect), and facilitate transactions among customers the clients inside the same network (effect network). They characterized the conditions to identify these two effects and the conditions for the two seemingly positive effects to turn negative in the equilibrium. The results were tested on a panel of 68 US banks over 20 years, and they found that the bank profits decline due to adoption and diffusion of IT investment, reflecting negative network effects in banking Industry. In this study I will use the same factors used by Akram and Allam (2010) to explain the Impact of Information Technology on The Financial Performance of Bank sector in kingdom of Bahrain. CHAPTER THREE METHODOLOGY Introduction In this part of the study, we build the methodology of the study that is characterized in terms of tools and method of measurement and tests for the problem of the study, taking advantage of methods and tools of previous studies, in order to guarantee the access to the methodology to obtain the information more I need and better results.

The independent variables ROE: Return on equity  measures a corporations profitability  by revealing how much  profit a company generates  with the money shareholders have invested. So it is the amount of the net incomes returned like a percentage of the capital stock.   Each banks ROE has been obtained for its annual reports and calculated as: Return on Equity = Net Income/Shareholders Equity CHAPTER FOUR ANALYSIS TESTING HYPOTHESIS Introduction This Section includes tow main topics, the first is about descriptive Analysis of the study variables through various descriptive statistical measures, such as: Central tendency measures, Dispersion measures, Mean, Median, Range and Standard Deviation; to describe the study variables. The Second topic represents testing the study hypotheses, and computing the regression model information. First topic, Descriptive Analysis Descriptive Analysis The descriptive analysis table in the appendix shows the following: From Table 4.1, which illustrates the use of Bahrain banks for I.T, we notes that average cost of H W in Bahrain banks reached the highest average in year 2009 (3,332,204) and this year was the lowest in the standard deviation (323,436), as well as the year that contains the largest cost for investment (3,103,500), which refers to the rise in investment H W by Bahrain banks. The second independent factor is the S W, its mean (medium) started with (1,085,277) and we notice that they are on the increase from year to year until it reaches in 2009 to (3,117,740) While the standard deviation of S W started with 940,060 then decrease to (865,657) and increase later in 2007 and again decreased to (805,459) in 2008 and lowest amount (236,654) in 2009. The minimum S W during the research period was (420,554) while the maximum was (2,950,400). We marked that the third factor which is the S D O had a mean started with ( 627,493 ) and ended with( 525,001 ) and noted that investment in S D O reached the highest value in the years 2005 ( ,000,000) and 2007 ( 720,000 ) while the lowest value was in the year 2008 ( 245,907 ) and the standard deviation started high in first year 2005 ( 526,804 ) and decreased to the lowest in the last year 2009 ( 35,281) . The M A I N mean (medium) started with (930,182) in 2005 and ended with (1,519,138) in 2009. While the standard deviation started with (805,844) and ended with (957,440). The minimum M A I N during the research period was (360,365) and the largest amount was (2,196,150). The fifth factor which is the T R N had a mean (medium) of (133,498), (142,611), (180,363), (147,626) and (94,051) the standard deviation started with 94,048 and ended with (36,697), the minimum T R N during the research period was (66,996) while the maximum was (280,000). The I N S U mean (medium) started with 48,220 in 2005 and ended with 99,966 in 2009 while the standard deviation started with 37,873 and ended with 13,918 the minimum I N S U during the research period was 21,440 while the largest was 109,808. From the previous table we note that the seventh variable COMM, the average cost in Bahrain banks started with 1,124,045 and continue increased upto (1,737,626). In 2009, the standard deviation started with 955,944 and ended with (1,148,871), the minimum rate during the period reached to the lowest of 448,091 and highest was 2,550,000 in 2009. The I M P mean (medium) started with (243,621) in 2005 and ended with (562,749) in 2009. The standard deviation started with (188,627) and ended with the (60,303); the minimum rate during the period was (110,241), while the maximum was (60,303). The ninth factor which is the C O N S had a mean (medium) of (63,192), (32,123), (38,552), (55,051) and (95,053) and the standard deviation started with (52,055) and ended with (35,281), the minimum C O N S during the research period was (14,245) while the maximum was (120,000). The S I T mean (medium) in the beginning 3 years were the same 65,307 years and in the last 2 years increased to (104,500) while the standard deviation started with 49,063 and ended with (21,920). The minimum S I T during the research period was 30,614 while the maximum reached to (89,000). The BCP mean (medium) in the beginning year started with (295,011) and ended in the last year with (430,744). While the standard deviation was beginning with (247,472) and decreased in the last year to (198,759). We note the minimum BCP during the research period was (120,022) and the maximum was (571,288). The dependent variable is the ROE which was marked by the year 2006 the highest revenue between the years of the sample, as it reaches the highest return of 19.230% while the standard deviation was started with 3.606% and decreased later to .495 % in 2009. The year 2009 marked the lowest return on equity, amounting to 9.600%. Regression Analysis I used Pooled Data Regression method because Ive tie series data (2005-2009) and cross-sectional data (2 Banks). I have mathematical model of the study is developed as follows: I used E views program to analyze the data, I also used pooled regression and multi-regression because we have more than one independent variable verses only one variable which is the R O E. The confidence interval is ( 95 %).

Roles Of Individuals And Societies :: essays research papers

Roles of Individuals and Societies   Ã‚  Ã‚  Ã‚  Ã‚  The early twentieth century marked a period of rapid industrial and technological change in a society which began to redefine the roles of the individual and society. Max Weber and Sigmund Freud were two revolutionary thinkers of the time who recognized the importance of this relationship and tried to determine whether the power balance between society and the individual was tilted in one particular direction or the other. A world becoming an increasingly complex and restrictive forced these thinkers to ask themselves if society had indeed finally become a force too dynamic for the individual to manipulate; that if in fact it was society that had mastered the man. Although both thinkers provide radically different views of culture and society they are both essentially trying to answer the same question: does the individual control society or does society control the individual?   Ã‚  Ã‚  Ã‚  Ã‚  The relevance of such an argument might first be debated, for one might first respond to this question with some doubt; surely we have control of ourselves, do we all not have control of our own faculties at this very moment? At this moment you are reading or being subjected to a reading of this paper, therefore if this indeed is not fufilling some immediate obvious desire it is accomplishing some sort of other goal. Likely this goal is to achieve an education but again we might ask ourselves why? Surely we all want to further our scholarly qualities and develop our minds but more likely this again has an underlying goal: to succeed in society. Society has shown us that in most cases it requires a good deal of education in order to succeed. Therefore we might entertain the question, is our presence here a product of our own desires or that of society's? The point of this reasoning is only to point out something we may not immediately recognize: regardless of what our own free will may dictate, we cannot help but be influenced by the values and morals of modern-day society. And it is because of this influence, the rewards which it offers and the punishments which it threatens, that the individual has found himself actually being manipulated by this larger body. Psychoanalyst Sigmund Freud expresses this point in his greatest achievement, Civilization and Its Discontents. Pointing out this conflict between the individual and society Freud concludes, â€Å". . . the two processes of individual and of cultural development must stand in hostile opposition to each other and mutually dispute the ground.† (Freud, 106) And then after describing the affects of civilization as a â€Å"drastic mutilization† of his desires, Freud

The Meaning Behind Alien Abductions :: essays research papers

www.angelfire.com/mt/montalk Souls can only incarnate inoto bodies with DNA responsive to and compatible with that soul. Because souls are shaped by experiences and thoughts, different soul types will reincarnate into different body types of the same species. As humans, their personality is influenced and restricted by the characteristics of their soul. Spiritual evolution is limited by one's biological, genetic, and physical composition. For instance, a dog cannot grow emotionally as we do because their brains are biologically incapable of perceiving the same range of emotions. Dogs also do not feel equal self sacrifice and devotion to truth that some of us humans enjoy, and we are therefore superior to them. Lastly, since all souls, once out of the physical body and deep into the stages of the afterlife, are essentially the same being, there is no place for evolution in the spiritual realm; all evolution occurs on the physical plane of existence. This is why planet earth is so valued by the powers that be. It is the perfect training, evolving, and learning grounds for positive souls with the privilege of physical presence. In this region of the solar system, without an earth, there is no evolution, and whatever pain a soul is in continues indefinitely until that soul can reincarnate to evolve out of its pain. Because souls evolve by earthly hardships, new types of souls can only develop by modification of the older ones over millions of years of evolution. Thus, if a sudden jump occured in the genetic sophistication of a species, a spiritual void would be left as the older souls would be outdated and incompatible with the newly created species. The new species would be born as still births unless some source of soul were available that is suitable with the DNA of that species. The human race was a result of drastic genetic engineering by a coalition of several alien species/races several hundred thousand years ago, each group putting its own spin on the basic human template. Most of the aliens themselves were products of undisturbed evolution upon their homeworlds. Since human evolution was catalyzed, the souls of our ancient primate ancestors could not reincarnate in the newer advanced bodies. Thus existed a spiritual void which was immediately filled with a new source. Considering it was aliens who created humans, these aliens must have had some reason to profit from the task. In fact, most alien bodies were too primitive to allow further spiritual

Rising Incidence of Alzheimers Disease Essay -- Alzheimers Disease Es

Alzheimer’s disease is the most common dementia that destroys brain cells and causes problems with memory, thinking and behaviour. According to recent statistics (Alzheimer's Association, 2010), Alzheimer’s is the 7th-leading cause of death in the USA with the number of people suffering from AD only in America over 5.3 million. It affects more women than men, causing differences in symptoms depending on gender. There is no cure which can guarantee a recovery for diseased people to date. However, more possible cures exist for diseased females. As per Brian Ott’s article on gender differences in Alzheimer’s disease, females have huge changes in behaviour comparing with males. This process is tightly connected with emotional instability, mood swings, wandering, and refers to personality change. Over listed symptoms are the first one to show up, but eventually there become more and more consequences of the disease such as frequent delusions, hallucinations, and sun-downing – the exacerbation of syndromes in the afternoon and evening, which makes a person in early stages of Alzheimer’s more antisocial and unadapted to a daily life. Such difficulties with communicating with people makes lives of patients very complicated, make them suffer of misunderstanding, and lead to depression as it was proved by American Psychiatric Association (1980). Indeed, 69% of people with dementia were suffering from depression (from Neundorfer, 2001: American Psychiatric Association, 1980). A group of researchers has found evidence of difference in language comprehension and memory regression between males and females: the latter are more vulnerable to such changes in cognition due to influence of sex hormones on the brain (from Ott, 2005: Sherwin, 1997)... ...llet, X., N.

How It Alters the Teen’s Future

Teen pregnancy is a thing that ultimately alters a teens future forever with negative side effects, In the United States, 2. 800 teenagers become pregnant each day. When I graduated in 201 1; out of al the girls I graduated with 10 of those girls have had babies. one of them Just had her second baby this year. think more needs to be done to make girls realize that it affects their future, their children's, the baby's tamer. and other tamily members. I couldn't Imagine having a baby at this age. My cousin became a teen mom at the age of 19 with her long time boyfriend.But, I see the struggle they have to make money to pay the bills. He works two jobs to support her and their child because child care Is so expensive. They don't regret having their son, but they regret dropping out of college. Teen pregnancy Is the leading reason teen girls drop out of school. More than half of teen mothers never graduate. of them earn a college degree by the time their 30. About d quarter of them have d second child within two years of their first. Teenage girls in relationships with older boys are more likely to become pregnant, han a teenage girl In a relationship with a boy her own age.Poverty Is associated with increased rates of teen pregnancy. 80 % of teen mothers have to go on welfare at some point due to less than one third of teen mothers receive no child support. Girls whose mother or older sister gave birth as d teen are more likely to get pregnant themselves. Teenage parents who can rely on family and community support, social services and child care are more likely to continue with their education and get a higher paying job as they progress with their education. In the united States alone 820. 00 teens become pregnant each year.Birth rate in the United States is the highest in the developed world and teen abortion rate Is also higi-n In 2006, the united States teen rate rose for the first time in fourteen years. Canada also trended towards a steady decline for both 15- 17 and older 18 – 19 teens in the period of 1992 – 2002. Majority of teenage mothers are not married to the tatner ot their children. Babies born to teenagers are at risk for neglect and abuse because their young mothers ere uncertain about their roles and may be frustrated by the constant emand of care taking.Children of teen mothers are more likely to be born prematurely with low birth weight. They're at a higher risk tor intellectual, language, socio – emotional, development disabilities and behavioural issues are increased. Children of teen mothers have a 31 % incidence of depression and a 25% risk of parenthood as a teen. Mothers are less likely to stimulate their infant through affectionate behaviours such as touch, smile, smiling and verbal communication or to be sensltlve and accepting their needs.Teen parents don't have the Intellectual or erformance in children of teenage mother also been noted with many of them being more likely to fail to graduat e high school, be held back a grade level or score low on standardised test. As a son born, to a young woman in her teens is three times more likely to spend time in prison. Only 20% of teen fathers marry the mother of their child, many teen mothers continue to live at home with their parents. Teen fathers may continue a relationship with the babys mother but its common the relationship to end and when it does many fathers don't have much interaction with their children.Teen dads are less likely to earn a high school diploma; the failure to graduate can be due to finical pressure resulting form having a baby to take care of. Despite the stereotype, there is increasing evidence that teen fathers want to be (and are) involved with their children, though this involvement may not always include financial support. Young fathers are more likely to have economic and employment challenges and are more often economically disadvantaged than adult fathers. A large percentage of fathers involve d in teen pregnancies are 20 years or older.Teen pregnancy and motherhood can influence younger siblings. One study found that younger sisters of teen mothers were less likely to emphasise the importance of education and employment. Younger brothers too, were found to be more tolerant of non- martial and early births in addition to being more susceptible to high risk behaviours. Many programs available for teen moms are based on income. If the teen mom's parents earn above the minimum income, the teen may be denied services which leaves the burden of the costs on the parents.Teen pregnancy has a negative affect on their children, the teen mothers, and teen fathers. More needs to be done to prevent teen pregnancy more education and guidance from parents. Also, more needs to be done to help teens who become pregnant and the teen fathers. I don't think theirs enough done for teen dads. With more support groups, financial help, helping with them (teen moms and fathers) graduating and ge tting their diploma. They shouldn't be shamed because they become pregnant at a young age, they should get the opportunity to graduate and have a better life for them and their child.
