Impact of Current Information Technology on Our Lives Essay

ACKNOWLEDGEMENT My deepest gratitude to my Ate Kristine and my parents who support and encourage me to pursue my chosen path, to concentrate to my studies, for all their kind and inspiring comments. My special thanks go to my grandma, who have given me great moral support in my studies and to our Almighty God, who have given me spiritual support to complete this term paper. I. INTRODUCTION Information technology (IT) ins probably one of the most significant developments in human history since the printing press. It has given rise to one of the most fascinating communications devices ever created, the Internet. It has come into our homes, our schools and our offices, tying us together in unprecedented ways. It is one of the most important developments in recent memory. Information technology (IT) is the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information by a microelectronics-based combination of computing and telecommunications. The term in its modern sense first appeared in a 1958 article published in the Harvard Business Review, in which authors Leavitt and Whisler commented that â€Å"the new technology does not yet have a single established name. We shall call it information technology (IT).†. Some of the modern and emerging  fields of Information technology are next generation web technologies, bioinformatics, cloud computing, global information systems, large scale knowledge bases, etc. A. GENERAL INFORMATION IT is the area of managing technology and spans wide variety of areas that include computer software, information systems, computer hardware, programming languages but are not limited to things such as processes, , and data constructs. In short, anything that renders data, information or perceived knowledge in any visual format whatsoever, via any multimedia distribution mechanism, is considered part of the IT domain. IT provides businesses with four sets of core services to help execute the business strategy: business process automation, providing information, connecting with customers, and productivity tools. IT professionals perform a variety of functions (IT Disciplines/Competencies) that ranges from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as management and administration of entire systems. Information technology is starting to spread further than the conventional personal computer and network technologies, and more into integrations of other technologies such as the use of cell phones, televisions, automobiles, and more, which is increasing the demand for such jobs. In the recent past, the Accreditation Board for Engineering and Technology and the Association for Computing Machinery have collaborated to form accreditation and curriculum standards for degrees in Information Technology as a distinct field of study as compared to Computer Science and Information Systems today. SIGITE (Special Interest Group for IT Education) is the ACM working group for defining these standards. The Worldwide IT services revenue totaled $763 billion in 2009. B. TECHNOLOGICAL CAPACITY AND GROWTH Hilbert and Lopez identify the exponential pace of technological change (a kind of Moore’s law): machines’ application-specific capacity to compute information per capita has roughly doubled every 14 months between 1986-2007; the per capita capacity of the world’s general-purpose computers has doubled every 18 months during the same two decades; the global  telecommunication capacity per capita doubled every 34 months; the world’s storage capacity per capita required roughly 40 months to double (every 3 years); and per capita broadcast information has doubled roughly every 12.3 years II. TRENDS IN INFORMATION TECHNOLOGY The wide range of information, data, and knowledge for problem solving and decision making are dealt with Information Technology. Before starting with the projects, students should be aware of authentication, and integrity features in their projects. Breaking of passwords and hacking can be avoided using these techniques. Anyhow, the various trends for projects are based on the emerging software technology. A. LATEST TRENDS a. Flash technology To add multiple types of external data to the given text, images, video, XML and to interact with web pages, Adobe Flash is used. It provides multimedia platform. The main purpose of this technology is to be used in advertisements and games. Both audio and video streams are supported by flash. One of the Object-oriented languages called ActionScript is the language used here by the developers. Flash player includes ActionScript Virtual Machine (AVM). The compiler, Just-In-Time (JIT), is used for MP3-based audio and bitmap graphics. Flash CS5 is the latest version of Adobe flash which was released on April 12, 2010. b. Microsoft Silverlight Microsoft Silverlight is developed on web framework and is similar to the functions of those in Adobe Flash. In addition, it also integrates multimedia graphics and interaction with a single runtime environment. Common Language Infrastructure (CLI) and its development tools are supported by Silverlight. The processor x86 with streaming SIMD Extensions (SSE) is  used by Silverlight. Also the other processors which support Silverlight include the Intel Pentium III and AMD Athlon XP. Any of the .Net Programming language is supported for Silverlight applications. The developing tools for the application can be used along with the .Net language but should be aware that they can target only the Silverlight core CLR for hosting the applications and not that of the .Net Framework CLR since both differs in their own functionalities. 4GDR1 (4.0.50524.0) is the latest version of Silverlight and was released on 03 June 2010. c. Open Source software Open source software is newly emerging trend which is one of the best options for the students. The source code can be modified by the students as per the objective of project. Hence Open source is much flexible than closed version software. Open source software is mainly developed on peer to peer production by collaboration of end product, source material. Open source software can be enhanced by anyone and if you join some open source developers community, you can learn a lot of things directly from the most knowledged persons in the developers community. Even the top companies like Google who are paymasters gives lots of importance to candidates who have worked in open source projects during the interviews. d. Cryptography Cryptography is the practice and study of hiding information. It also refers to confidentiality. It is often seen as a â€Å"black art†, which means something others don’t understand but you need to understand. Cryptography is one of the essential aspects for secure communication. There are many aspects of security and applications ranging from secure commerce to private communication and to protect passwords. Cryptography is necessary for secure communication but it is not sufficient by itself. Here, the text is encrypted first; i.e. the plain text is changed to inarticulate garbage. The end user does the reverse process i.e. decryption, where the original text  is retrieved. There are a lot of algorithms in this area which is used in real time for data protection in sectors like banks, Research, Password Protection and so on. e. Nanotechnology Nanotechnology is the study of controlling properties of an atom and molecules. As the name indicates, it deals with the study of structures sized between 1 and 100 nanometer. It is said that, nanotechnology has a tendency to create new materials and devices which can be used in future in a wide range of fields such as medicine, energy production, electronics and bio materials. As they are very small in size, nano structures have a tendency to change its state for transformation of energy. The two main approaches used in nanotechnology are Bottom-up and Top-down. In bottom-up approach, materials and devices are built from molecular, a component which later assemble themselves chemically and follows the principles of molecular recognition. In top-down approach, nano-objects are constructed from larger entities without any atomic level control. Biotechnology is the best example to show the use of nanotechnology in various fields. The upcoming trends mainly focus on security and hacking. Mobile application for iPhone and Android are great areas to explore with good revenue opportunities as well. If you want to stand out from others, instead of going for some courses, try to contribute for an open source project. B. BUSINESS TRENDS Just a few decades ago, businesses had little in the way of office machinery except typewriters. Fax machines were new; only Xerox made copiers, and the computer was a monster that took up an entire room. These behemoths were housed almost exclusively on college campuses or in government laboratories. With the development of the personal computer, the situation changed; it was so quick it sometimes seems like it was overnight. At first, businesses were happy to use computers because their word processing programs made typing projects much easier. But using a computer like a high-powered typewriter  defeats the purpose of having the machine in the first place. Companies soon discovered that their PCs could do a great deal more. Companies began to network offices together so that they could share files and work on the same projects from distant locations. They connected to the Internet and put out advertisements to draw new customers. And perhaps one of the most significant business developments to come with IT is the creation of the electronic marketplace. Companies that sell their products over the Internet greatly increase the number of potential consumers who see their offerings. Even if the company is not actively selling goods, a website is a tremendously helpful tool. A well-designed, easy to navigate site can stimulate interest so that a potential customer calls or writes for further information. Other business applications of IT include â€Å"data mining,† â€Å"knowledge management,† and â€Å"modeling and simulation.† (Kalil, PG). This last is particularly interesting, as it allows companies to build prototypes in the computer. These prototypes perform exactly the same way a three-dimensional model would, and yet are far less expensive than building the â€Å"real thing.† This way, if the prototype doesn’t work, there isn’t the strain on the company’s resources there would be if a real model (car, plane, truck, train) had been built. If it does work, it can be put into production quickly. C. FUTURE INFORMATION TECHNOLOGY TRENDS There’s no denying that we are in a worldwide downturn. Government are in debt; jobs are being cut; houses are being repossessed and people because it. However, there is a way to plan for the declining eminent and that is through IT guidance. If you are like most people, the last thing on your opinion is paying for tuition, especially in a specialty as baffling as information technology. However, IT education may be your label out of the slump and into a fulfilling and stable career. For most of us, our prospect is not set in pelt, especially with the downturn. There is no concrete way of aware that you will forever be in the site, or even with the visitors you are with now. However, IT guidance can organize for a potential in information technology at any sector. The  diligence needs IT technicians whether you work in television, marketing, communication, client check, etc. IT technology can open doors to more than just your own effective Future Information Technology Trends environment. You can take these skills and concern them to other sectors and industries as well. This will make the leap to another career in the upcoming much fewer overwhelming, if that time ever comes. Technology and Telecommunication: While many people are trailing their jobs in marketing, buyer ceremony, factual estate and construction, more and more people are verdict their mission via telecommunication. This is because, while the nation is gradually lessening, the â€Å"nation† is blossoming. Websites are in stable penury to IT help including webmasters, graphic designers and programmers. This Future Information Technology Trends trend will prolong as the internet is one of the best customs to join to the world and will only maintain to grow in the future. Technological trends in the future: According to the Bureau of Labour Statistics, the technology world will maintain to upsurge with jobs in IT increasing by 16% in the next ten existence. This is sooner than most other industries in the United States due to the many technological advances within many industries. IT Training for all Industries: even if you never want to dine in a career as an IT technician, information technology exercise can help prepare you for advancement in your own sector. Information technology exists everywhere and this is why it’s important to advantage the skills desirable to understand the information technological phase of your sector. IT is Universal: Another important touch of information technology is that, while some systems modify from troupe to troupe, and from country to country, they are all relatively the same. This means that, if you desire to do so, you can move and convey with career guidance in IT. Spend a year in Japan since the sights and running in IT on the section, or take your skills to Australia when the frost months get too cold. The possibilities Future Information Technology Trends for those with information technology training not only transport from trade to industry, but they also outdo continental boundaries as well. D. EMERGING INFORMATION TECHNOLOGY TRENDS Traditionally, hotels were mostly dependant on cards and paperwork at the front desk to keep in meet with old and current customers. They were chiefly at the mercy of the wishes of vacationers to succeed, and on their own pains and force to be inclined for budding surges or long droughts of tenancy. Luckily, such inconvenience and old-fashioned methods are long since ancient, gratitude to advances in information technology. The first question in which information technology became important regarded billing. Old-fashioned paper-based book-keeping time-consuming and inefficient, and was not able briefly to tell a lodge holder what the avow of their lodge was. Luckily, advances in modern proof keeping tolerate for a lodge holder to keep pathway of what they have on hand, how much of it they have, and how much it outlay. Accounting is complicated, but future software, especially that tailored to the sole needs of the hospitality activity, helps to permit lodge owners to make smart decisions. Services and harvest that are no longer worn can be instantly cut off to prelude money, while those who show want can be augmented in magnitude or bespoke to diminish the important tradition. Most hotels are recurring with booking quarters and reservations over the telephone, but information technology has prolonged well past that. Hotels can now work with different online trek companies and booking military to have Emerging Information Technology Trends their rooms booked online, with no indigence to employ classy force. This also allows a lodge to announce their open rooms and unusual deals promptly to people who would be most to grasp them, instead of killing much money advertising in an unfocused mode. High worth information technology hence allows for better arrangement and management of booking to tolerate a lodge to better maximize residence, and to know in proceed when large groups or prop period are approaching. This allows a lodge manager to make strategy about transient pole, good times to renovate or inflate, or other concerns, because he/she can decide the state of their hotel currently and for the next few months with only a few clicks on the laptop. The advances in information Emerging Information Technology Trends technology proffer well afar booking, however. The internet is  necessary for vacationers who fancy to associate those back home, and for those nomadic on topic to get in feel with the bureau. Therefore, wireless internet has become a very ordinary and very helpful tune for hotels to supply. Many interest minded persons even entail that an hotel tender internet army so that they can keep running while on the street. Luckily, such army are easy to supply, as all that is required is a wireless router and diverse plans to guarantee the whole hotel is filled with the practice. Modern advances in wireless internet also permit for the wireless internet provided for hotel visitors to be used to group the hotel itself. Security cameras, door stresses, and other policy basic to hotel sanctuary and shelter can be Emerging Information Trends wired into the interact, so that workforce are alerted when a door is propped open, a fire alarm goes off or suspicious activity occurs. Though the hotel guests are wholly unaware of it, this variety of added safety and guarantee keeps them careful, and in the occasion of a puzzle they will almost surely appreciate the benefits of such system. As difficult as it is, information technology in the hospitality activity is still going ahead. Intelligent booking systems enable hasty and helpful guest opinion, along with the ability to predict who is likely to use the hotel again and tell them via e-packages or passage letters when a good deals appear. Hotels with scope mass or other guest services can tender menus online, allowing for abrupt updates, high-class photos, and other behavior to allow guests to see and order services before they even arrive. There also advances in terms of payroll and list which make information technology Emerging Information Technology Trends an effective asset for reduction money and maximizing profits. The sole quality of the hospitality trade makes it a great place for new and emerging information technology, and farther-opinion hotel owners and managers are forever looking for smart tools and software to invest in. E. HEALTHCARE INFORMATION TECHNOLOGY TRENDS The utilization of technology in healthcare has opened the method for improvements in a limit of areas. One of the advantages and payback of fitness tending technology is the additional people are extant diseases like feeling and blight disease due to the fitness to identify them earlier than formerly skilled. With this ability comes the subsidy of being able to use a method that may be fewer extreme than one beloved as the disease grows. With a disease like Tuberculosis, as it metastasizes, the talent to struggle it and eliminate it gets harder and harder. Although, one more use of technology in healthcare has brought us newest drugs that can aim more precisely the particular scourge cells along with being more embattled in other areas. It has also brought us latest radiation Healthcare Information Technology Trends tools that can be far extra accurate and not have to use the shotgun manage to dig up to the tumor. The ray could even be bent about key body parts like glands and arteries so as not to injure them when focusing in that territory. One interesting and futuristic loan is the utilization of robots. You can now have a preset prostatectomy with an outcome that may be to the profit of the enduring. With the use of a robot in surgical procedure there is a slighter Healthcare Information Technology Trends opening and large incisions which is fewer torment for the tolerant, there is a smaller quantity of blood failure, an exclusive hazard of rigid cuts about delicate nerves and tendons which may allow the unwearied a pompous choice of not having poorer effects from the surgical procedure, and typically a shorter drape about in the hospice and a shorter recovery time. The accuracy of the robot is far more rigid than a surgeon using his/her hands lonesome. Robots are also programmed in such way that they can grip complicated situations. Another zone where robots are worn is in mandatory middle surgery. Again the accuracy and precision of the tools show the way to a bigger unplanned of a quicker recovery time and minus anguish to the patient. The finer incisions and the possibility of less blood harm are one advantage to using robots in a middle surgery. The dab Vinci Healthcare Information Technology Trends robot worn in the heart and growth surgeries and has the opportunity to be  worn in a range of areas where precision and accuracy are vital. III. EDUCATION Although computers are now common in the classroom that has not been the most significant step in their use as educational tools. I believe that distinction has to go to distance education. The concept is not all that new, because the idea of remote classrooms with a teacher appearing on television has been in place for decades. But the idea of conducting an entire class over the Internet is radically different. In distance education, the students may never set foot in a classroom at all. They will interact with the teacher and with their peers via email; they may participate in lectures via some sort of instant messaging service. The assignments are posted by the instructor, and the completed assignments are returned to him/her through email. Attending class by accessing the Internet does of course mean that the student cannot participate in a live exchange with his peers and the instructor, so in that sense the spontaneity of the classroom is missing. However, for students in very remote areas, or when classes are offered at one campus and not another, it is a viable solution, and it is made possible by IT. IV. PERSONAL USAGE Of course the single biggest item here is the personal computer. Having a computer at home has revolutionized life for millions of people around the globe. We tend to get our news from the computer; we may find ourselves in a discussion with someone on the other side of the planet; and we tour museums and shops in distant cities among many other uses. Many people now work from home (â€Å"telecommuting†) rather than physically going to the office. This saves road congestion and helps diminish pollution. Children and teens use the computer to help with their homework, and with the Internet, they have the entire world as a resource. V. CONCLUSION The impact of IT on society is hard to overestimate. Many of the developments, as I’ve indicated, have been positive, but there are some negatives as well, specifically a tendency to spent more time alone, or interacting only with the computer rather than with real people. Still, for most of us, IT has made a sizeable impact, and a positive one, on our lives. VI. REFERENCES http://www.cisp.org/imp/april_99/04_99kalil.htm http://www.wikipedia.com

Love: Filipino Psychology Essay

Filipino Values for Productivity Values have much to do with the way we act. It is, therefore, important that we understand our Filipino Values. Understanding our own Filipino Values means looking closely into our beliefs, mores, customs, norms, and traditions, examining them closely, looking at their positive and negative polarities, and harnessing the positive polarities of our values as norms of our behavior at work. Our values and norms greatly affected by the several rulers that came on our country. Some norms are inspired by the Spanish rulers; also, some norms are inspired by the Americans, Chinese and Arabs. Thus, with the variety background of our norms, ethical or unethical, we cannot deny the fact that we management to survived from our struggles with the help of our combined norms coming from the different foreign rulers who ruled and help us mold the so called Filipino Values. Even if these values are copied by our ancestors from the different nationality, we tend to claim that these values, combined by the other values we have learned are the values that will consist our own Filipino Values. Values have much to do with the way we act, in the organization, this is truly manifested. As discussed in my first reaction paper, I did presents the strengths of Filipinos in terms of working under an organization. Filipino values for productivity implies the characteristic of Filipinos of hard-work ( masipag at matiyaga). Also, I did present the ability of Filipinos to make use of the little resources available in the workplace. Giving emphasis on the ability of Filipinos of being creativeness depicts a picture of Ma-utak or Madiskarte. Truly Filipinos possessed these strengths but it out weighted by the weaknesses that I will present in this reaction paper. This is from the book of a popular human behavior book author, a Filipino who conducted study in order for him to know the negative values that affect the quality production of Filipinos. Negative values of the Filipinos that affect the quality production are the following: 1. Ningas kugon 2. Bahala na System 3. Baka makalusot Notion 4. May quality controller naman 5. Hindi naman mababawasan sweldo ko 6. Hindi naman malalaman kung sino ang gumagawa ng mali 7. Di na baling ma-reject, may fixer naman 8. Bakit and iba diyan, mas marami pang reject 9. Tahi lang ng tahi 10. Mamaya System. 11. Kahit may reject babayaran pa rin tayo Some of these negative values are mostly seen in a plantation where Filipino workers usually work. To separate the ones that generally manifested even if office and in some other work place, in this reaction paper I will just discuss the necessary values that greatly affect the productivity of us, Filipinos. â€Å"Ningas Kugon ay isang idioma na nangangahulugang sa umpisa lang magaling at kalaunay mag-iiba’t hindi na ipagpapatuloy ang magandang pagsisimula. † To start right and not to continue a good start as you go on to the work. This is a trait that contradicts the essence of hard-work. For Filipinos, first impression is very relevant to build up your image to your boss. Well, this bad, working is not building your image but it is about working to help the organization attain organizational goal. Maybe, you can build up your personal image to your co-employee and boss as your second priority in the organization because I cannot deny the fact that in an organization human relation exist. Doing good from the start will take Juan from humble beginnings to the top if only, he would just continue that good performance from that of the start. The mere point of motivation is being demolished having this kind of trait. This kind of Filipino value is commonly seen in a Campaign Period in an Election. Candidates are here and there, building up and making some name to the people in order for the people to vote for them. In the campaign period they act like he person that could be trusted and the person who will represent them and answer some social problem but when this candidate win and sit in the position, the fairytale is over. In the start, you could see and talk them, but as the time goes by, it will be the opposite. Filipinos are now fighting this kind of situation by which they tend to know the past performance of every candidate and decide who do not have this kind trait. Relating it to productivity, performing good at the start and not continuing that really affects productivity because the product that you will be giving to your customers will be highly observed especially to those customers who are passionately buying your customers. â€Å"Hay nako, nagbago ang lasa ng tinapay nila dati malinamnam ito. † The satisfactory value from the customers is one of the factors that the workers should consider in order to attain success on productivity. â€Å"Ang pagsasawalang-bahala ay isang idioma na nangangahulugan ng pagpapabaya sa isang bagay at iisiping magiging maayos din ang lahat sa bandang huli. † Bahala na means â€Å"I do not care what will happen†. The thought of ‘everything will going to be alright’ also constitutes the this so called Bahala na System. Keep pushing on something that you know it may be not be successful is one of the examples of the bahala na system. Such notion of leaving everything just the way it is and praying that it will going to be okay is the main ideal of this system. For just an example, in a construction project of a bridge, the project team leader knowing that the newly constructed bridge is unstable and not ready to use, but the city government is pushing for its use and then the project team leader let the city government for its use. â€Å"Bahala na, yan ang utos sakin eh†, is the thought of leaving behind the project and not letting yourself be involved in the liabilities. â€Å"Bakit ang iba diyan, mas marami pang mali? † Counting the numbers of your co-worker’s mistakes will not benefit you neither the organization. Filipinos possessed a trait keeps on rotting an organization until it will go down, it is the Crab Mentality. Crab Mentality has to do with the productivity because it one the elements that tend to decrease the average of quality production of Filipino workers. Looking for a loop hole in the personality of your good performing co-employee will is not an act of helping the organization attain its aspired status. Instead of making some rumors about that person, why won’t you make him/her as one of your motivating factor to contribute your efforts to the organization? An exam would be the practice of politicians running for the same position and they present each other’s mistakes and wrong doings in the past to the people. Pulling down those who are trying they best to climb in the ladder of success is one of the Filipino Values that is considered a hindrance on good productivity of the organization. â€Å"Marami pa naming oras, mamaya nalang yan. † Procrastination, this is an act that also, diminishing the essence of hard-work. Filipinos are fan of saying the words – LATER or WAIT FOR A WHILE. We Filipinos have this innate attitude of doing first what is necessary and then doing what you wanted to do. But, having in mind the urgency of the things that needed to be done do not requires a quick action, we tend to postpone it for a while and continue to do the things that you wanted to do. Thinking about when is the deadline of a project and doing the whole project the day before or on the last minute before the submitting hour or day. In the a plantation, procrastination is not observed for the company should produce more than what is demanded in a fixed period of time. Well, in a company producing items this is true, but in an organization running an office giving services, the urgency is observed. Services should always be there, prepared, so when the time comes, if that specific service is needed. In some cases, services that are prepared before an actual demand by the customer is a good quality product. There is this saying by the Filipinos, â€Å"Aanhin pa damo kung patay na ang kabayo†, services or products that are late will result to poor satisfactory feedback from the customers. â€Å"Hindi na baleng ma-reject, may fixer naman na mag-aayos. † Filipinos love on depending everything to something they know that it can help or cure or fix anything they have done wrong or they will do wrong. â€Å"Di bale nalang† means quitting on it or sort of quitting on something and letting it go the way it is. And thinking about the fixer that will easily fix whatever is wrong in the item is the principle of depending on the machine. Instead of making the item in the right manner in order to lessen the use of a fixer machine, Filipinos continue to do the wrong manner of producing the item just meet the deadline. In this point of view you can now see the relationship of procrastination with this trait of depend the item to the machine and to the time of its deadline. With this kind thinking, it manifests the attitude of sacrificing the quality production. The â€Å"Okay na yan† attitude is also one of the elements of this act. Concentrating on quantity and not on the quality of the product is the main thought of this attitude. Filipinos, usually we, as a student would say – â€Å"Okay na yan, basta may maipasa lang† as a â€Å"pampalubag-loob† in not meeting the desired quality of the project or usually in times of examinations. Settling on the quantity produced and not on the quality is not accepted in the organization strictly observing the quality of the products or services being produced. â€Å"Katamaran – ito ay isa sa mga hindi kanaisnais na katangian ng mga Pilipino na kung saan ang mga dapat na gawin ay hindi naisasakatuparan sa kadahilanang nagkukulang and motibo para maigalaw ang kanyang katawan upang magtrabaho’t magbanat ng buto. † To sum up all that is being discussed above, the word laziness is the back bone of such acts and behavior of Filipinos towards productivity. Laziness means not being productive for your organization’s desired status in the future. Lazy, as a song lyric described, it is an act of doing nothing. Laziness is the opposite side of hard-working. Keeping asleep or just lying in your bed could be one of the common acts of laziness. But in the organization, laziness deals about the behaviors of an individual inside the work place showing nothing or no any single accomplishment at all. Laziness is also in line on the idea of not wanting to work inside in the work environment. It indicates the factors of unmotivated or unsatisfied with the management’s way of handling the working conditions they have gone to. Some Filipinos are people who prefer to take a day for a rest and do nothing instead of doing something that are actually to be done on an appropriate time. Some Filipinos tend to do a certain work and as it goes by and by, they will left it unfinished. Some Filipinos work well on the starting period of his job, but eventually take the opportunity to not work effectively in the succeeding time of his job. While some other Filipinos love to depends everything on something that can be the answer for their undertaking. Well, even in any of this behavior you are under, the bottom line will be the picture that depicts Juan, waiting for that ripe guava to fall right into his mouth.

Week 5 Forum Bay of Pigs Failure - Assignment Example The location of the invasion was also very inappropriate considering the lack of an escape route at Bay of Pigs. The location had been chosen quite hurriedly without a consideration of many factors. It proved very hard for the attackers to escape and engage the government in guerrilla warfare. President Kennedy was much worried about an obvious involvement of America in the operation and therefore supplied the operation with only sixteen obsolete aircraft. However, this was done without a consideration of the Cuban fleet. Another major mistake arose when against the advice of the military officials the President reduced the initial fleet from sixteen to eight. That decision was an indication that the whole operation was headed for failure. At the planning stage, the Secretary of Defense actually admitted that the plan was bound to fail considering the haphazard manner in which the operations were conducted. It was much important to totally focus on destroying the Cuban air force at the outset of the operation. However, this was impossible considering the limited attacking fleet1. Part of the failure of the invasion is attributed to the poor coordination between intelligence and operations. Indeed, it is seen that Kennedy did not have much knowledge on intelligence related affairs and did not therefore regard it as essential. For the success of such an operation, much information should have been gathered on the Cuban regime. Information on the training of the solders, demography and the defense ability of the military should have been gathered effectively. It was important to have a close association between intelligence and operations so as to provide the necessary preparation and preparedness for the invasion. Indeed, the fear of exposure was the major concern of America in the whole operation. In this case, everything was done with a need to ensure that such exposure was not possible. However, this was also the major cause of failure in the

Why you cannot prepare a tax return showing these deductions unless he Assignment

Why you cannot prepare a tax return showing these deductions unless he can provide the receipts - Assignment Example The IRC Section 274 prescribes strict and specific documentation requirements for all business expenses claimed for travel purposes. Due to this prescription, the receipts will be required to fully substantiate your travel deductions (Pope, Anderson, Kramer, & Bandy, 2007). It is against the federal law to complete tax returns without the back up documents to verify the reported information. Moreover tax returns are prepared under the penalty for perjury and therefore it is equally vital to confirm all the details in the process of completing the tax returns. In view of this, i am under the standards prescribed in the IRC Section 6694, which demands that I prove the documented information before I prepare the tax returns for you. The fact that the reported figures cannot be adequately substantiated due to the absence of receipts, the benefits associated with some of these large deductions will be lost. As a matter of fact, there is a high probative value in these contemporaneous records of which it is for your own advantage that you avail them before the tax returns are

Bitch first Essay Example | Topics and Well Written Essays - 1000 words

Bitch first - Essay Example For many decades, the society has considered the word offensive, more so when used to refer to a woman (Donalson 136). Until recently, the word ‘bitch’ was a derogatory name for a whore or a woman with loose morals (Low 96). Nevertheless, the contemporary society has fully embraced the use of the word even in inoffensive situations such as when referring to female colleagues and in idiomatic expressions (Dines, Gail, and Humez 78). Essentially, Queen Latifah brought significant influence on the use of the word through her rap music that continues to gain wide acceptance to date. Although the mention of the word ‘bitch’ in reference of a person was hitherto a taboo, the influence of rap as stated by Queen Latifah has made the word acceptable to the current generation. In the ancient times, the society was most conservatives and the use of certain words such as ‘bitch’ was limited to the animal reference and not humans (Allen 104). However, with r apid modernization, the use of the word to insinuate various scenarios has been widely accepted especially considering the huge number of slangs that the modern English has brought (Dines, Gail, and Humez 78). ... Although the traditionalist still abhor the use of the word ‘bitch’ to insinuate a human character, the modern use of the word has surpassed the virtual rule (Dines, Gail, and Humez 78). Perhaps it is appropriate to insinuate that Queen Latifah frequently named women in the same word in her lifelong musical career and in the world of art (Allen 104). This actually means that the use of the term in a social manner is acceptable in many social platforms as opposed to the ancient times when its mere mention was an abomination (Keyes 79). While the mention of the term bitch in the modern social context may elicit mixed reactions, it is widely believed that it appeals to many people in the same sense that it may offend others (Dunn 41). Therefore, one ought to consider the audience and the immediate social context whenever they plan to use the word in their conversation in order not to attract negative judgment from conservative audience (Donalson 136). Perhaps another aspect of the use of the term ‘bitch’ in the contemporary context is the reference to awful things (Dunn 41). For instance, one can refer to life as a bitch to connote the various challenges that come along in this world. In this regard, the use of the terms ought not to offend anyone, as it is used positively (Allen 104). Perhaps the use of the term ‘bitch’ came into popularity because of being used in many idiomatic expressions (Hess 82). While most of the idioms that use the word ‘bitch’ may not have any intention of negativity in them, it is important to admit the fact that modernity has only worsened the offensiveness of the word, particularly considering the disgusting idioms that use the

Catedral Essay Example | Topics and Well Written Essays - 250 words

Catedral - Essay Example The narrator realizes his loneliness, his lack of communication, and his use of alcohol and drugs to overcome these shortcomings through this meeting and thus the story ends on a positive note that there is still hope. The first hint of the narrator’s loneliness is when his wife says to him â€Å"You don’t have any friends,† (Carver, 2009, para 10). His constant use of alcohol also bears testimony that he wishes to drown these feelings by consuming more and more alcohol. Also at one point in the story when the wife goes to sleep and Robert wishes to stay and chat with the narrator, the narrator seems surprised and is glad to have company in his daily ritual of staying up late and drinking. Another important issue that the narrator realizes is his lack of communication. He is not able to communicate properly with his wife. He is surprised to see his wife smiling when she comes home with Robert thus hinting that he does not know what pleases his wife and what does not. He is not even mentioned in the conversation between his wife and Robert. When he, bored of the conversation, switches on the television, his wife looked at him with irritation. (Carver, 2009, para 47). Likewise from the beginning he was uncomfortable with the notion that a blind man was coming to visit and would stay in his house. He had not been around any blind person to have any fore-hand knowledge of how to treat a blind person. Eventually he ends up asking tactless questions for instance the side of the train that Robert sat on while coming as it would not have mattered to and even when he is addressed to by Robert, he replies in monosyllables and phrases. He also changes some preconceived notions about blind people as he is surprised by the presence of a beard and absence of dark glasses on a blind man as well as his skill with the fork and fingers during dinner. Then he also faces immense difficulty in describing a cathedral to Robert. When Robert makes the narrator draw the

Food and Drink in Society Essay Example | Topics and Well Written Essays - 1250 words

Food and Drink in Society - Essay Example The availability, choice, and cheapness of food that the free market has brought about means that we have become accustomed to eating what we want, when we want, how we want- with little to no thought about the consequences of our consumption patterns. This has been encouraged and designed by a political and economic system that is profit- orientated rather than social or environmentally orientated. Traditionally food was farmed, sold, cooked and eaten in a very different way. As global capitalism has shaped our lifestyles it has also affected how we eat. Since the 1970 ´s there has been a huge explosion in fast food outlets providing cheap, colorful food leading to problems of obesity in countries that have embraced the fast food culture- â€Å" it seems wherever Americas fast food chains go, waistlines inevitably start expanding† (Eric Schlosser, 242). However in the last few years there has been a public reaction and rejection of the fast food culture. The Slow Movement set up in 1989 is one such example â€Å"to counteract fast food and fast life, the disappearance of local food traditions and peoples dwindling interest in the food they eat, where it comes from, how it tastes and how our food choices affect the rest of the world.† (Slow Food Movement, Homepage) There are signs that there is a return to historical food and drink choices, with the popularity of farmers markets, organic food sales increasing â€Å"The value of the market increased by an average of 16 per cent a year between 2003 and 2008† (Daily Telegraph) and celebrity chefs such as Gordon Ramsey extolling the virtues of eating seasonal, British food. Recent trends in food consumption point to a clear return to traditional and historical ways of eating, slower, local and healthier! In the UK we have seen the merging of many different cultures, British society is made up of a huge variety of cultures each bringing with them their own food revelation. The culture of food is often shaped by the

Clinical Depression Overview Research Proposal Example | Topics and Well Written Essays - 1250 words

Clinical Depression Overview - Research Proposal Example When depression strikes, a person will not only feel down, it may affect his ability to function normally in society, and in some extreme cases, it provokes the person to commit suicide. Being the most common mental disorder in the United States, depression affects over 17 million Americans each year ("Understanding Depression"). With these, depression is obviously a serious condition that should on no account be ignored. In identifying depression, certain factors such as gender, age, and culture should be taken into account. The manifestations of depression in different people are likely to vary in accordance with the aforementioned factors (Smith, R. Segal, and J. Segal). For instance, an elderly man would most probably exhibit different signs and symptoms of depression from a teenage girl. However, there are common signs and symptoms that we can watch out for. These signs and symptoms can be categorized into those involving the person's mood, his thinking, his behavior and physical manifestations ("Depression - Types, Causes and Symptoms"). Symptoms that involve the person's mood include feelings of sadness, hopelessness, helplessness, numbness, emptiness, anxiousness, and guilt. People who are depressed find it hard to enjoy and feel good about things that they used to do normally ("Depression - Types, Causes and Symptoms"). A depresse...People suffering from depression also find it difficult to think clearly and they have poor concentration and memory ("Depression - Types, Causes and Symptoms"). In some cases, as earlier mentioned, depressed people have suicidal thoughts and some actually attempt to kill themselves.

The Power of Hoping and Believing Essay Example for Free

The Power of Hoping and Believing Essay Everyone has a shadow in their life. They may be academic failure, failure of marriage, and failure in one’s career. Normally it is the forbidden area which no one can access. Most of the shadows can be forgotten as time goes by. Some of them, like a scar in the heart, undoubtedly leave their mark. Everyone has different ways in facing life’s difficulties, such as escape or solve it. The power of hoping and believing is very strong. It is through these beliefs that changes and discoveries are made. It is due to the acts of hoping and believing that advancement and modern technology thrive on. When we have a great idea and if we hope and believe in it, chances are, we can discover something that could help make our world a better place to live in. Lauren Slater in the â€Å"Three Spheres,† writes, â€Å"Sometimes I wish time stayed solid, in separable chunks as distinct as the sound of the ticking clock on my mantle right now. In truth, though, we break all boundaries, hurtling forward through hope and backward on the trail made by memory. †(7) In the quote of Three Spheres, Lauren Slater naively wishes that time can stand still instead of escaping to go to Mount Vernon. It is because the memory in a specific period and the picture of Mount Vernon made her escape from the difficulties in her life. For me, I think it is the writer’s wish that time should stand still and be compartmentalized like a source of reference to probably make her statements and generalizations correct. But in truth, there is none. Because what may be true now can be proven wrong in the future. There are no compartments and we all move forward. We add on to the general knowledge and we just look back not for reference of something constant but only for memory’s sake. In addition, we always want to be time travelers that go back to our lovely memories. It is because we always consider the real word as cruel. A lot of people don’t want to face difficulties and suffering. Aside from that, no one knows what will happen in the next moment. The future is a secret. We don’t want to take the risk since the difficulty will come in the next minute. We humans always feel scared when we face something we don’t know. Many people are scared of the dark because they can’t see further. Death is a mystery since we don’t know exactly when and where it will happen. People always feel interested and scared about death. Death is a thing that we can’t get back from once we enter it. It seems to have no doors for us to learn about. The only way we can learn about death is from religion. A major thing that you would probably want to compartmentalize or stay on are your happy moments. In most cases, people who suffered a tragic loss of a loved one would wish that time stood still so that they can continue to be with their loved one. On some instances, a loved one, a good business venture or a prime economic stage that had gone bad would make people want to wish for the time to stand still and remain during their â€Å"good times†. Typically, we want to stay in the â€Å"good times† when we lack the confidence and the ability to solve our problems. However, as we all know, time is constantly moving and can only be compartmentalized for memory of how we thought or how we felt at that moment and can never be something there for us to continuously have those thought and feelings. Time moves on as life moves on. In psychology, a person stuck in a subject is a self- induced hypnotic. â€Å"I can do it! I can do it! † We always say this when we are facing difficulties. I kept saying this before I gave a speech. I understand it does not give you a great help, but believing in yourself is very important. As it is human nature to constantly want better conditions of living, we always think of ways to improve on what we have right now and we hope and believe that our ideas could be a great contribution to the betterment of our society. As can be seen in technology, our computer has evolved from a big desktop system to e-notebooks. From x-rays we now have ultra-sound, MRI and CT scan. From the movies and film industry the reel became, betamax, VHS, Laser Disc, Compact Discs, DVD, and USB and now we can even download movies through the internet. Visiting her old home, Mount Vernon, is the first step for Lauren Slater to face her cruel history. People can understand her reason for escaping her difficulties. Although we may sometimes want time to stand still, it is our nature to hope and believe for something better to come our way, and only look back at memories. If time really stood still then our world would be a boring place to live in because there will be nothing new and nothing to look forward to. Hoping and believing gives us life and energy to move forward and make our new day exciting, adventurous and worth living.

Impact Of Television On Sexual Behaviour Of Youths Media Essay

Impact Of Television On Sexual Behaviour Of Youths Media Essay INTRODUCTION Television, radio, films, newspapers, magazines, books, and other media are increasingly persuasive and influential in peoples lives around the world. New technologies such as the Internet, cell-phones and chat rooms, have changed the nature of the media experience in significant ways through the information they provide to users. The information obtained from mass media maybe constructive or detrimental and it is for that reason there is need to assess the impact it has on teenagers sexual behaviour by mainly focusing on televised programmes. Background of the Thesis Televised programmes do qualify as one of the convenient sexual educators in our culture but laden with contradictions. TVs accessibility and popular appeal make it an excellent instructor, offering a convenient way to learn about sex without embarrassment which usually arises between parents and their children when discussing sex related issues. While TVs sexual messages are not always explicit, they are abundant, and often provide information youth do not get elsewhere. Through its dialogue, characterisations, storylines, and themes, television presents adolescents with numerous verbal and visual examples of how dating, intimacy, relationships, and sex are handled. On the other hand, concern is often expressed that the messages TV sends about sexuality are limited, sometimes stereotypical, and potentially harmful. The concern is that the prevalence of sexual content on TV inadvertently overemphasizes the role of sex in male-female relationships. Of equal concern is the impression t hat television provides a one-dimensional picture of sexual relationships and sexual encounters are always spontaneous, romantic, and risk free. Thus, because of the prevalent yet limited nature of TVs sexual content, researchers and educators have become interested in/whether viewing of these portrayals is associated with distorted expectations, irresponsible sexual decision-making, and permissive sexual attitudes. Although the research in this area has been sparse in Kenya, research findings do associate amount of TV viewing with viewers sexual attitudes, expectations, and behaviour. First, greater TV exposure has been linked to viewers attitudes about sex and sexual relationships. Both heavy regular consumption of and experimental exposure to sexually-oriented genres, such as soap operas and music videos, have been related to expressing more liberal sexual attitudes, to being more accepting of sexual improprieties, and to more negative attitudes toward remaining a virgin. Together, these findings but not limited to, provide tentative evidence of a link between watching sexually-oriented programming and viewers own sexual attitudes, expectations, and behaviour. The effects of television consumption on teenagers behaviour regarding to sex are of increasing interest to educators, policy makers, program planners and the society as whole. The concern is that the extent to which frequent consumption of media with high levels of sexual content and low levels of portrayal of responsible sexual conduct is a pivotal influence on young peoples subsequent sexual behaviour, including the responsible use of protection from pregnancy and disease. Research done in United States has demonstrated that young people are heavy consumers of sexually- oriented media including TV, both broadcast and cable channels, videos, movies, magazines, and, more recently, the internet. The researcher acknowledges that the above mentioned relationship cannot be generalised across cultures especially Kenya and United States, however televised programmes do carry sexual content across board. Content analyses have also demonstrated that broadcast television contains a high, growing and increasingly explicit dose of sexual messages, and that a proportion of such messages display or model either restraint or contraceptive use. However, scientific evidence has not yet established a causal relationship between exposure to sexual content in the media and teenagers attitudes concerning sexuality and their own sexual behaviours. Therefore a detailed research that addresses the nature and magnitude of the role of television in teenagers decisions regarding sexual intercourse and protection from disease and unintended pregnancy might create data which could guide future policy making and programming, both in the government and in the media industries. Statement of the Problem The role of television as a sexual educator in our culture is perceived to be inappropriate. On the one hand, televisions accessibility and popular appeal as an excellent instructor, does offer a convenient way to learn about sex and sexual behaviours without embarrassment. While televisions sexual messages are not necessarily visually explicit (which can be either non-verbal or verbal cues), they often provide information that teenagers may not receive elsewhere. One dimension of involvement to be considered is viewing motivation, or viewers expected uses of television. People use and select media (television) to gratify specific needs, and that specific uses lead to differences in behaviour and outcomes. According to this construct, people exhibit varying levels of activity when using the media, differing in their selectivity, attention to, and involvement with the content viewed. However, while the expectation is that the effect of television content will therefore depend on ones level of active involvement. It is argued that facilitative activity, which includes selectivity, attention, and involvement, is more likely to enhance television effects on sexual behaviour, whereas inhibitory activity, which includes avoidance, distraction, and scepticism, should deter teenagers involvement in sexual activities. Focusing on the two dimensions of facilitative activity and inhibitory activity, the researcher seeks to determine to what extent televi sion viewing impact on teenagers sexual behaviour. Thesis Objectives In order to achieve the purpose of the study which is to determine the impact of television on the sexual behaviour of the youth by exploring aspects of television use that are associated with teens sexual behaviours and expectations, hence the research has based its objectives on: To investigate whether television content affects the sexual beliefs and behaviour of the youth To investigate what sexual content the youth pay attention to and how they interpret what the see and hear. To investigate whether television as a form of media can be used to promote responsible sexual behaviour Thesis Questions What sexual content do teenagers pay attention to, and how do they interpret what they see and hear? Do sexual media content affect teenagers sexual beliefs and behaviour? Can the mass media be used to promote responsible sexual behaviour among teenagers? Hypotheses The study will test the following hypotheses; Sexual behaviour among the youth is influenced by what they see on television. Television is appropriate channel to educate the youth on responsible sexual behaviours. Television has become a peer to the youth. Limitation of the Thesis For comparison reasons, the research is limited to researches done on the similar topic on argument impact of television on the sexual behaviour of youths. The study sample of teenagers between the age of 15 to 17 living in Starehe constituency may not give a fully representation of the each and every youth in the country. Its important to note that there no readily available research or documented information regarding to television viewing among teenagers in Kenya which would have added value to this research. The study is limited in collection of primary data specifically in interviews and questionnaires. The question of whether the respondents will accept appointments, attend, answer and return the questionnaires in good time is delimitation to the research. It is important to mention that not all respondents will be able to reply to the questionnaires adequately due to reasons beyond the researchers control, while some may have clerical errors. Concerted efforts will be ensured for better response and retrieval of important information from relevant sources. Motivation This study is important for Kenyan society, in understanding the impact of television on the sexual behaviours of youths. Furthermore, the information attained in this study could also help in understanding sexual decisions that are made by youths. As the country and the world as a whole are working towards combating the HIV and AIDS epidemic, it is imperative to try and understand the different aspects (peers, parents, television, as well as the media as a whole) that contribute to such decisions, particularly since statistics have highlighted that they are more vulnerable to being infected and are at the risk of experiencing teenage pregnancy. Thesis Structure The thesis will be segmented in chapters; the first chapter will concentrate on the sociological analysis of the topic whereby the study will look at the problem, its root-cause and what has been done by other researchers on teenagers sexual attitudes and behaviour regarding to what they watch on televised media. In this particular chapter the study will look at various communication and psychological development theories which tend to explain teenage sexuality. The subsequent chapter or segmentation of this study will document the research methodology in collecting primary data, sampling of respondents, data collection and analysis. The study uses descriptive survey research design whereby the researcher will describe a scenario to a respondent who will then give in-depth response on the same. The research population is drawn from teenagers of age 15-17 years old whereby stratified sampling will be applied to select the respondents. The final chapter deals with elaboration of the communication strategies available such as injection theory and agenda setting theory followed by the justification of the communication theories through the research findings and details on the implementation of the proposed thesis. It will end with general conclusion based on the findings expressed from data analysis and discussed literature in view of thesis objectives. CHAPTER ONE Introduction This chapter deals with literature concerning previous studies relating directly and indirectly to the influence of television on adolescent girls sexual attitudes and behaviour. Furthermore, this chapter furnishes a detailed description of how different researchers view the underlying assumption of this study together with a consideration of the different methodologies employed to conduct the various studies which have resulted in similar conclusions. This chapter further describes how television has influenced other aspects of adolescent life and behaviour. Although the study solely focuses on the impact of television, the study also describes mass media in order to broaden the perspective regarding media influence among adolescents. In addition, the researcher indicates how television influences other behaviours other than sexual. The reason of including other manifesting behaviours is to illustrate that if television is able to influence teenagers in this manner, it may also influence their sexual attitudes and behaviour. Teenagers and Sexuality Teenagers undergo adolescence which is viewed as a time of adjustment and is often characterised by turmoil resulting from issues regarding identity and sexual identity and orientation. A key period of sexual exploration and development occurs during adolescence. During this time, individuals begin to consider which sexual behaviours are enjoyable, moral, and appropriate for their age group. Many adolescents become sexually active during this period. Sexuality is a developmental milestone among teenagers with which each generation struggles. Sexuality encompasses behavioural components with boundaries of sexual activity moving in an increasingly permissive direction. Perceptions appear to be constant through the ages while only the circumstances change. An emphasis on individual freedom and rights-driven culture in societies may be influential in this apparent permissiveness. A number of factors which include media and the internet, urbanization, electronic communication, peer influences and the breakdown of traditional parental and community structures also play a part. Therefore, we look at these factors in more detail. Factors Influencing Sexual Behaviour There are many factors that contribute to and influence sexual behaviours among adolescents. Family structure, age, gender, parenting styles, and type of parental communication have all been pointed out as factors that influence teenagers behaviour. However, family structure has been of particular interest to most researchers as more adolescents are being exposed to family disruption and are moving away from traditional lifestyles. The positive or negative impact of these changes on adolescents may also influence their sexual behaviour. Teenage sexual attitudes and behaviours are also influenced by: Biological and psychological factors within an individual this refers to age, level of maturity and gender Close relationships in family and peer groups refers to the people with whom a teenager enjoys near, close or intimate relationships. Socio-cultural contexts such as race, religion, school and the media refers to the kind of environment from which a teenager come from, their belief systems, the kind of education, as well as the kind of media (television, print media, internet, radio), to which they have been exposed. Consequently this research aims at determining television as an influencing factor on the sexual behaviour of teenagers in Starehe constituency. One potential but largely unexplored factor that may contribute to sexual behaviours among adolescents is exposure to sexual content in the mass media. The average youth spends one third of each day exposed to media, and the majority of that exposure occurs outside of parental oversight. Although mass media have been shown to have an influence on a broad range of behaviours and attitudes including violence, eating disorders, tobacco and alcohol use, surprisingly few studies have examined the effects of mass media on adolescent sexual attitudes and behaviours. Theoretical Perspectives: Attitudes and Behaviours The potential for mass media to influence behaviour has been supported through a number of different psychosocial theories, hypotheses, and models. Although there is considerable variation in theoretical mechanisms by which media might affect adolescents sexual attitudes and behaviours, most posit that sexually related message content and behaviour act over time as stimuli to change consumer psychological, physiologic, and behavioural function. The study thus analyses two theories namely Social-Learning Theory and Cultivation theory to relate the sexual behaviours among teenagers. Social-Learning Theory Banduras social-learning theory provides ample evidence that even when children and adults have not actually performed a behaviour, they can learn by imitation. Bandura identifies three main processes involved in learning: direct experience, indirect or vicarious experience from observing others (modelling), and the storing and processing of complex information through cognitive operations. This theory suggests that behaviours are learned and that they are influenced by social context: Television is seen as an increasingly influential agent of socialization that produces its effects through childrens propensity to learn by imitation. The premise of Social learning theory is that it focuses on viewers personal connections with the portrayals via identification and perceived relevance to the self. The dimensions here emphasize on television characters as models of behaviour. The hypothesis proposes that specific critical portrayals may exert a stronger force on impression-formation and image-building than might the sheer frequency of television characters and behaviours viewed. This notion emphasizes the power of individual performances to affect viewers, most likely portrayals that speak to the viewer in some way. Banduras theory predicts that teenagers will imitate or model what they see on television when those television personalities are rewarded or are not punished for their behaviour, and are perceived as attractive, powerful, and similar. Indeed, evidence suggests that perceiving TV figures as sexual role models is associated with more permissive sexual attitudes, more extensive sexual experience, and great er dissatisfaction with ones sexual status and sexual experiences. Thus, it is expected here that the contributions of TVs sexual content will be stronger among teenagers who more closely identify or connect with the portrayals of television personalities. In light of the aforesaid, the most common examples of social learning situations are television commercials, movies and music videos. Sexual content displayed in these programmes may suggest that certain sexual behaviour renders teenage boys and girls more attractive and admirable. The theory further indicates that human sexual behaviour is governed mainly by social conditioning, rather than endocrinal stimulation. Sexual modelling presented on television teaches affectionate techniques, reduces sexual inhibition, alters sexual attitudes, and shapes sexual behaviours by conveying norms: for instance, which behaviours are socially acceptable and which are not. Cultivation Theory Cultivation theory posits that heavy exposure to mass media creates and cultivates attitudes more consistent with a media-directed version of reality than with reality itself. Up to this point, the dominant theoretical model supporting this research has been the cultivation theory. The cultivation theory (Gerbner, Gross, Signorielli, 1994), proposes that televisions consistent images and portrayals construct a specific portrait of reality, and as viewers watch more and more television, they gradually come to cultivate or adopt attitudes and expectations about the world that coincide with this portrait. Although this model has typically been employed to explain the impact of TV violence, it has been applied successfully to the cultivation of attitudes about gender roles, politics and marriage. Accordingly, if content analyses indicate that sex on TV is glamorous, prevalent, recreational, and relatively risk free, the cultivation model predicts that frequent teenage television viewers will be more inclined than sporadic viewers to hold and accept this perspective of sexuality. Media portrayals and messages might affect the behaviour of teenagers over time by enabling them to acquire new attitudes and behaviours or by changing the likelihood that they will perform new or previously learned responses. However, while the results reported thus far are provocative and informative, and do support the premises of this model, they offer a limited analysis of televisions role in the sexual socialization process. It is argued here that viewing amounts should be seen as only one avenue through which TV exposure might affect teenagers. Indeed, the processes by which television viewing shapes viewers attitudes and expectations are varied and complex, with several factors contributing at the same time. Therefore, to better examine contributions of television exposure, other dimensions of viewing need to be considered. In particular, a key element missing has been the role of viewer involvement. The study believes that teenagers perceptions of the portrayals and their connections with the material are likely to be critical factors in the socialization process. Drawing on the premises of several theoretical perspectives, I have outlined four aspects of viewer involvement which I believe may play an important role. It is my argument that teenagers who feel more connected with the material and who are more involved in the viewing experience will be most affected by it. To contextualize the Cultivation theory, the study discusses viewing motivation, active viewing and perceived depiction. Viewing Motivation One dimension of cultivation theory involvement to be considered is viewing motivation, or teenagers expected uses of television. Gratifications concepts contend that people use and select media to gratify specific needs, and that specific uses lead to differences in viewing behaviour and outcomes. While some viewing is believed to be more ritualized, in which a television is used to fill time, escape, or provide company, other television use is more instrumental, in which viewing is purposeful and goal-directed, perhaps driven by information-or arousal-seeking. In relation to the study, we focus on instrumental motives, more specifically on viewing TV to learn about the sex. The expectation is that the effects of TVs sexual content will be stronger among teenagers who are intentionally using TV to learn about sexual behaviour. Active Viewing A second dimension of Cultivation theory focuses on the level of active viewing. According to this construct, teenagers exhibit varying levels of activity when using the television, differing in their selectivity, attention to, and involvement with the content viewed. However, while the expectation is that the effect of TV content will therefore depend on ones level of active involvement, the direction of this effect is unclear. The suggestions are that active teenage viewers are more affected by televisions messages; others indicate that passive teenager viewers are most vulnerable. In reconciling this debate, a current perspective suggests that different ways of being active contribute to different outcomes. It is argued that facilitative activity, which includes selectivity, attention, and involvement, is more likely to enhance television effects, whereas inhibitory activity, which includes avoidance, distraction, and scepticism, should deter them. Focusing here on facilitative ac tivity only, the expectations are that the socializing effects of TVs sexual content will be stronger among teenage viewers who tend to engage in more facilitative activity. Perceived Depiction A third dimension of involvement considers the perceived realism of the portrayals. Although most television programs are fictional, there are many aspects of the portrayals (such as the clothing, physical settings, dialogue, and situations) that closely resemble those in real life. Consequently, most notions predict that televisions impact will increase the more realistic its content is perceived to be. Evidence supports this premise, with cultivation effects appearing to work stronger for those who view the portrayals as realistic. Thus, it is expected that the socializing effect of televisions sexual content will be stronger among teenage viewers who perceive its portrayals as more realistic. Influence of Television on Teens Television has proven to exert a large influence on peoples attitudes and behaviour. It has been found to reflect and possibly shape the attitudes, values, and behaviours of young people. According to them, this medium has become so influential that it serves as a teacher, often providing a common source of information to young people. The role of media in teenagers lives has raised concerns in many respects, such as violence, sexuality and body dissatisfaction. Although numerous studies have demonstrated the effects of media on various behaviours, including violence and aggression, social stereotyping, and pro-social behaviours, the systematic process of examining sexual content on television and its impact on adolescent sexual behaviours is in its infancy. Studies have demonstrated clearly that sexual content is pervasive in TV programming, movies, music videos, and magazines; however, much less is known about sexual content on the radio (including remarks by presenters) and the sexual content of video and computer games. It is surprising that only a few studies have assessed the sexual content of the television, and none have specifically examined this content in relation to teenager exposure. This is particularly troublesome given that what little evidence there is indicates that the television programmes may contain the most sexually explicit content. Studies on the effects of television on teenagers sexual behaviour have found that prime-time programmes and music videos, focusing on sex outside marriage, promote more justifiable attitudes about premarital sex. Two cross-sectional surveys have linked frequent exposure to sexual television content and transition to sexual intercourse. However, because time order was not clear in these studies, Ward and Friedman further state that it is credible to conclude that teenagers who were having sexual intercourse were also those most interested in sexual content in the media, rather than that exposure to sexual media was accelerating the initiation of their sexual activity. The single longitudinal study on this topic found that adolescents (12-17 years old) who watched television shows with more sexual content were more likely than those who viewed fewer shows with sexual content to have engaged in more advanced sexual behaviour, as well as sexual intercourse, up to one year later. Larson is of the opinion that the exposure to portrayals of sex may affect adolescents in developing beliefs about cultural norms as well. He states that television may create the illusion that sex is more central to daily life than it truly is and may promote sexual initiation as a result, a process known as media cultivation. Exposure to the social models provided by television may also alter beliefs about the likely outcome of engaging in sexual activity. Social learning theory predicts that teens who see characters having casual sex without experiencing negative consequences will be more likely to adopt the behaviours portrayed. Although televised sexual portrayals can theoretically inhibit sexual activity when they include depictions of sexual risks (such as the possibility of contracting an STI or becoming pregnant), abstinence, or the need for sexual safety, this type of depiction occurs in only negligibly of shows with sexual content. As a result, sexual content on television is far more likely to influence sexual behaviour among teenagers than discourage it. Teenage Sexual Behaviour in Kenya It has been documented that modernisation increases opportunities for sexual encounters and provides new models for sexual behaviour. The results suggest that modernisation favour transgression of the more restrictive traditions that existed decades. The scenario in Kenya regarding to teenage sexuality, little has been done to study the trends on the issue. Some of the close related studies done have mainly focused on sex education and reproductive health among adolescents. Problems related to sexuality and related behaviours seem to play a central role in the lives of many teenagers. In many parts of Kenya sexual debut begins early and in the absence of information and services. They state 7 out of 10 young people in Kenya have had sex before the age of 19. This high level of sexual activity is associated with risks such as HIV/AIDS, pregnancy, unsafe abortion, economic hardship and school dropout. Currently 5 in 10 girls in Kenya have begun childbearing before age 20 years. In most communities in Kenya, adolescents are faced with many of the same problems and violations of rights that may lead to sexual abuse. In their report, they have identified some reasons to explain this situation; the break down in traditional family systems in both urban and rural areas, influence of the mass media and modernisation as well as the lack of access to information and services are just some of the factors. In some cases they have pointed out that there is poor packaging of information for teens consumption hence having a negative impact on their sexual behaviours. In compounding this, it illustrates that not only do teenagers lack the right information and skills they need to make sound, healthy choices, but they are at particularly high risk of serious, long-term consequences of poor decision-making about sexual activity regarding to STIs, sexual abuse and early parenting. Narrowing it down to area of study, Kenya boosts over five national television stations and cable television. These stations broadcast various programmes featuring music videos, films, educative programmes, soap operas, all these shows run under various themes which may or may not have sexual connotations. Due to limited dedication to sex education among teens, the outcome is that these teens will rely on their own judgement or peer advice to make decisions regarding to sex. Thesis Critique Based on this review, the study identified many gaps in our knowledge of the sexual content of various television especially Kenya, the amount of exposure to it by adolescents, and the impact of this exposure. Moreover, there is a noticeable scarcity of well-conducted, scientifically rigorous studies that examine the impact of sexual content in the television media on sexual behaviours among adolescents, and there are no studies that have longitudinally examined the cumulative effects of sexual content in different types of media. It is critical that longitudinal research be conducted, and within the multilevel context of child development: that is to say, different groups of adolescents (defined by age, geographic location, tribe, domestic situation, and other variables) have different media diets, and identical diets may have differing effects depending on a number of factors. Based on this review, future studies should survey parents to assess the effectiveness of parental involvement, communication, supervision, and monitoring of media sexual content in the media in influencing the sexual attitudes and behaviours of teenagers. Also there is a need to evaluate adolescent and parent media-literacy education to determine best-practice interventions and their impact on youth viewing choices, interpretation of content, and sexual attitudes and behaviours: Intervention studies are needed to examine whether current media-literacy education has an impact on adolescent sexual attitudes, decision-making, and behaviours and how such programs may be improved to best protect teens. Throughout the study, there no are tangible researches in relation to teen sexual behaviours done which has taken into account early initiation of sexual intercourse, number of sexual partners, other sexual behaviours such as oral sex, dating violence among teenagers. Conclusively, this study categorically urges that there is need to address potential mediating variables such as puberty, peer factors, society and family factors (e.g., parental supervision and monitoring of media use); only in such ways can we determine the effects of television on adolescent sexual attitudes and behaviours. Conclusion This chapter has focused on discussing the theoretical framework that underlines this study. A review of social learning theory and cultivation theory with the main emphasis placed on cultivation theory. The importance of observing modelling behaviour, attitudes and viewing motivations of teenagers is addressed, as is the fundamental assumption of social learning theory and cultivation theory.

Programmable Logic Controller System Plc

Programmable Logic Controller System Plc Two decades ago, machines were simple and work in factories was, for the most part, manual in nature. Machines were designed to be manually controlled. Today, if people look for around them will find many things have the control systems, which are necessary to organize the complex devices. The control system is of primary importance for devices and machines in factories, aircraft, cars, and even in some home devices. For this reason, life has become easier and production has dramatically advanced. Now, the control system is acting on behalf of humans, helping them for example to avoid risks in chemical factories, which can be extremely dangerous for humans. Today, it is difficult for people to avoid the use of control systems in the work place. Control systems control complex processes, which regulate the production in huge factories. Without automated control systems, factories face many problems, which would otherwise be very hard to find a solution to. With the beginning of the modern industries, the engineers needed systems to help them to accelerate production and to get high quality at a low cost. Electronic systems in the form of sensors and switches were invented to monitor and control manufacturing and reduce labor and production errors. Switches and sensors were needed to complement programming and hardware and to speed up the analysis of input data and obtain the results to assist the engineers in processing steps. The first system and software used in this area was the SCADA system. However, this system was complex and could not be linked with other monitoring systems. Hence, they invented the PLC, which in turn facilitated the process of programming. Also, it contained many possibilities including its ability to connect easily with other systems in production lines to assist in the development of the production process. PLC, which plays an essential part in the process of automation and control, is one of the most importa nt systems in many factory production lines, and it has more features than other systems. History of PLC Even after Programmable Logic Controllers (PLCs) were invented, a number of problems with relays remained to be worked out. Many enhancements occurred in the 1960s. In the 70s, they improved more. The ability to communicate between PLCs was added. This created a space between the controlling circuit and the machine it was controlling. Other problems had occurred in the 1980s, but they were controlled. Also during the 1980s, PLCs were made much smaller. Many more ways a PLC could be programmed were developed in the 90s. Overall, industries still use PLC in many ways and it is likely they will continue to be used for a long time to come. (Amunrud, 2002) Definition PLC stands for programmable logic controller, which is a device with many useful and helpful applications. PLCs are used in place of other electromechanical systems. In addition, PLCs can also control the systems of production, manufacturing, and semiconductor machines. PLCs can be designed to be used in extreme situations such as, high temperature, high humidity, and in conditions of extreme noise around very large machines .The data of PLCs can be very different. For example, PLCs in factories are all about speed and accuracy, so they depend on the ingredients and measures. However, PLCs used in traffic systems are all about organization (SIMATIC manual 2004). How PLC Works: A programmable logic controller (PLC) receives and collects input data from measurement devices, such as sensors and switches, then analyzes information of these input data at a high rate responding with program instructions as a process computer. After that, the PLC sends back the results as output data to the final devices, like motors, based on outcome estimated (Bern and Olsen, 2002). According to Bryan (1997), PLCs are capable of storing instructions, such as sequencing, timing, counting, arithmetic, data manipulation, and communication, to control industrial machines and processes. Reprogramming a PLC accepts changes on the functional operation of a machine system without main physical changes in the control or output system components or wiring (Cox, 2001). Therefore, a programmable logic controller needs an integrated system consisting of software and hardware. PLC hardware components A complete programmable logic controller (PLC), including all input/output (I/O) modules, is called a station. Every station has at least one module rack containing a power supply and a central processing unit module. Input/output modules create the link to the machine or plant. The parts of a station were illustrated below: Power supply (PS): it provides internal supply voltage, which is either 120V/220V AC, or 24V DC. A central processing unit (CPU): the CPU, which stores and processes the I/O data, is a memory and processer. Input and Output modules (I/O): they are receiving and sending data through network from the measurement devices to motors. Interface Module (IM): it connected the different racks with each other. A programming device: the two main things in the programming device are communicators and personal computers that help the programmers to create and insert the programs to the PLC. Human Machine Interface (HMI): it is a display and touch panel where operators can observe and manage the critical equipments. Those PLC components are working together to reach the objective of controlling the system .The input modules, or points, used by a PLC depends upon the types of input devices used. Some input modules or points react to digital inputs, also called separate inputs, which is either 0/1, on or off statements. Other modules or inputs react to analog signals. These analog signals represent machine or process conditions as a range of current values or voltage. The primary function of a PLC that has input circuitry is to cause these various switches to convert the signals and sensors into logical signals that can be used by the CPU. The CPU evaluates the status of inputs, outputs, and other variables as it executes a stored program. The CPU then sends signals to update the status of outputs. The output modules convert control signals from the CPU into either digital or analog values that can be used to control various output devices. The programming device is used to enter or change the PLC s program or to monitor or change stored values. Once entered and programmed, the associated variables are stored in the CPU. In addition to these basic elements, a PLC system may also include an operator interface device to simplify monitoring of the machine or process. Figure 2.0 below explains how the process of how PLCs connect in industry. Figure 2.0 this figure explained the whole system work. In addition to these basic elements, a PLC system may also include an operator machine interface device to simplify monitoring of the machine or process. Example shown below, pushbuttons (sensors) connected to PLC inputs is use connected to a PLC output through a motor starter (actuator). No programming device or operator interfaces are shown in figure 3.0. Figure 3.0: It show the input, CPU and output In previous figure 3.0 it describe the input signal which is came from pushbutton and received by CPU module in PLC rack which analyzing the data and send it to the motor starter then start and stop the motor depends on the type of signal. Sensors are devices that convert a physical condition into an electrical signal, such as a pushbutton that are connected to the input of a PLC. An electrical signal indicating the order (open or closed) of the pushbutton contacts is sent from the pushbutton to the PLC. Actuators that connected to the PLC output are devices that convert an electrical signal to a physical order from a controller, such as a PLC. A motor starter is one model of an actuator that regularly connected to a PLC output. Depending on the status of the PLC output, the motor starter either supply power to the motor or prevents power from flowing to the motor (figure 4.0). Figure 4.0: more description on PLC from discrete Input to discrete output In figure, 4.0 it is described in more details when the PLC rack received the signal which is came to input module then send the signal to CPU which analyze it and send the result to the output module. PLC Programming: Numerical systems are useful in most programs, as they are when used in conjunction with Programmable Logic Controllers to make programs. The basic function of programming devices is to show, store, and operate. The numerical system is the most important element of programming a Programmable Logic Controller. The number systems usually encountered while using programmable controllers are base 2, base 8, base 10, and base 16. These systems are called binary, octal, decimal, and hexadecimal, respectively. Using a binary numerical system, which uses 2 as the base, and only allows the use of digits 0 and 1 where there are no 2s, 3s , and so on, is used in programming. In devices such as computers and programmable logic controllers, the binary system is useful. It is an easier way to design programs to deal with machines that analyze between only two entries or numbers to start or stop. For example, 0 and 1 represent on and off, respectively. The octal system acts in place of the binary n umber system by using fewer digits. The octal system uses the number 8 as a base and only allows eight digits starting with 0 and ending with 7 (0, 1, 2, 3, 4, 5, 6, 7). Also, with other systems, using hexadecimal further reduces the number of digits in the programming language and coding system (Bryan, 1997). Leader logic is the main method of programming used in PLCs. This method is used to build the whole program by using the numerical system to save the program in the CPUs memories. In this section, many programs have their own language and PLCs have their own special language, which must be expanded and developed. Programming languages helps the programmer and user to build and enter a control program into PLCs. Types of PLC languages that are used in programming consist of three types: Leader, Boolean, and Grafcet. The Leader and Boolean actually work in the same way, but they have different ways in their insurrections, which are shown and how to enter into PLCs. The Grafcet language implements control instructions in a different manner, based on steps and actions in a graphic oriented program (Bryan, 1997). PLC programming languages are used in the SIMATIC programming languages to write a user program to control the machines or devices. Programmers have many choices of programming languages and programming methods in SIMATIC. The most useful programming language in PLCs is LAD (Ladder Logic Diagrams). Also programmers can resemble programs by using electronic circuit diagrams (Function Block Diagrams FBD). Those familiar with textual languages or coding languages can use and handle Statement List STL with many complex variables (SIMATIC, 2003). Programmable logic controllers have different languages that offer different advantages and benefits for the process engineers. Different languages in PLC applications help engineers in the complex projects that give the process engineers flexibility in determining which is the most appropriate language to use. The differences between languages in programmable logic controller are in the structure but not in the instruction. For example, LAD uses block symbols language, but STL uses coding language. Figure 5.0 below is helpful in describing the differences between the two languages (SIMATIC, 2003). Figure 5.0: it describe the differences between LAD, STL and FBD Figure 5.0 describes three different languages. The first row explains the LAD language. Element symbols, which are described NO contact, stand for normally open contact with the signal 1 (yes) if it is active and 0 (NO) if it is not active. The next symbol NC contact, stands for normally closed contact. In the second row, the FBD language blocks describe other kinds of language in same manner but in different shape. Normally open contact in FBD language appears as a box and it is possible to write the value inside the box. On other hand, normally closed contact is in the same shape of normally open contact but with a small circle by the side of input to express a closed state. STL language has a different formula but the same instruction coding system. In the development of programming, engineers can convert the program display from one language to the other to check and correct instructions. All subprograms and instructions in different languages for devices and machines could work together as one program to achieve the process needs (Berger, 2008). Advantages of programmable logic controller (PLC) PLC has many advantages that make it a unique process controller. The advantages are always increasing. Programmers, operators, and engineers prefer the PLCs over other control systems, because of their simplicity, security, and reliability. PLC Is Simple and Flexible No control systems are easy or simple, but PLCs have emerged as comparatively simple and easy to other leading process control systems. In PLC is easy to add or remove any ending device without affected the whole process. Also, PLC has the flexibility to monitor and correct the system anytime even though the plant On-line situation or Off-line situation (SIMATIC, 2003). PLC Is Distributed Allocated controlling system implicates many computers and stations on network occupied to gather. PLC is created to make allocated controlling system smooth with the networking faculty and equipments that are inseparably joined to it. PLC is considered the sender and receiver on writing network system files. Also, PLC is able to work with the hardware parts and the software side of the computer, including those operating systems Windows 95 and NT, the Macintosh, XP and Vista (SIMATIC, 2003). PLC Is Secure The security in PLC is excellent. It is one of the first control program that has the most powerful protection from risks, losing data and the damage to the users. Those features have made PLC a sophisticated and useful control program system. Comparing PLC with SCADA from the security side PLC has the greatest result (SIMATIC, 2003). PLC Is Reliable Both reliability and security are important to each control system. PLC is one example of those control systems, which have them. PLC affords multiple points of reliability measures, starting with PLC itself and ending with many of its features. For example, pointers and automatic type conversion are included in PLC . Before PLC is finished doing and start a program it has to check if there is any mistake that it can fix by itself or ask the user about it (SIMATIC, 2003). Conclusion Programmable logic controller (PLC) language has helped develop the control system, and it has become the most useful language. Programmable Logic Controllers have become the language that most companies and factories use. They supply and support engineers with what they need and they keep operators protected from hazardous machines. The potential of programmable logic controllers in controlling systems is almost limitless. Programmable logic controls have fed and supported control systems in many ways. Most process computers utilized in factories with humans have more advantages than disadvantages as a secure system when dealing with complex process. Programmable logic controllers have proven to be an effective and helpful tool in many industries in the past. With their many advantages, they will continue to be useful in the future as well.
