The diamonds water paradox - Movie Review Example This can be viewed as the reasons behind Argyle’s successful entrance into this market. The firm’s dictatorial styles is used in marketing diamonds where customers have to take what is available or leave it is under threat from Argyle (Peng 316). Argyle diamonds may be of a lesser quality as compared to those of De Beers, but are on high demand. This is because world diamond prices have reduced in the past few years. Customer tastes have changed to an increased demand for cheap, high quality diamonds supplied by Argyle. This has led to most of these customers demanding more of Argyle diamonds than those from De Beers. Thus, De Beers faces a threat as it shifts from the diamond industry monopoly to an oligopoly market type from the competitor Argyle. In this case, both companies are providing the same product. The view from De Beers’ side is that the presence of Argyle has no effect on their monopoly. The firm is believed to be the sole producer of high quality, premium diamonds. The diamond market today is not only dominated by De Beers and Argyle. Other firms from other nations such as the Russians have today made an impact in the diamond market on a global scale, thus causing De Beers to risk losing its advantages as a monopoly. However, despite the presence of other upcoming competitors such as Argyle, De Beers can still be classified as one the most enduring monopolies in the world (Kanfer 402). When the diamond industry was an oligopoly in the 20th century, there were still other substitutes for diamonds such as emeralds and rubies. However, most still believe that there is no other gem that exhibits the same characteristic, such as the diamond. This was perhaps the belief created in the advertising campaign in the late 1990s by the only diamond seller. This supposition may still be there; therefore the diamond as a unique product has no competing

The detailed study will work as the starting plan for the launch of product in UAE and it will then be made to change gradually with sale increase from the expectation to the aspired. It will change with course of time depending on the success and failure of the program. We are going to study about the marketing tactics in this section. Marketing Objective Target Market Citizens of United Arab Emirates will be the target market for Big-Bazaar. Presence of lot of expatriates will be boon for the company as they have the ready visibility for this brand. For Company the basic target group will be the shoppers who are willing to spend their money economically and those who the value of their money. Therefore our target customer will be the people who are married and who belong to the middle class family. Company will also be cashing on the presence of Indians there. (Retail Market in Middle East) Expected Sales Sales objectives define the amount of sales company want to have in very first year. Since company is totally new in the United Arab Emirates, we are planning to have a sale of around 234 million US $ or 734 Million of AED in the very first year with its operation in nearly 12 stores in 12 different areas. Profit Expectation Profit Expectation of Big-Bazaar will also be bit on lower side only. With the sale of total of 734 AED of grocery, Big Bazaar will be gaining overall profit of 23 million AED. This shows that we are expecting Big-Bazaar to be profitable in very first year only and we are expecting it to earn a big name through its operational efficiency. Promotion Mix Advertising Objective Main objective of advertisement is to make customers aware of the brand and make them take our brand image in the same way in which we want to communicate. Therefore here operational efficiency doesnt matter until and unless you really tell the customer that we are excellent in managing operation in the same way as Honda stresses the quality part of its product in its advertisements. Therefore here the objective will be to communicate shopper that it is the cheapest shopping point. Company will have to communicate the low price wit high quality of its brand. Company cannot play with brand name by tarnishing g its image with its cheapness. Company should communicate the proud of giving genuine product at such a low price. As always we need to first segment the population of United Arab Emirates in categories. Since here in United Arab Emirates per capita income is much more than India, therefore the cheap price will not be only factor that will attract consumers towards their product. Big-Bazaar should be showing the good shopping environment over and above the capability to sell it so cheap. After segmenting population we need to target the middle income segment population. After setting the target company needs to set its positioning to provide cheap and good quality products. (Westwood, 2006) Media Mix We are planning to have the media mix which can make big-Bazaar to approach every single people in United Arab Emirates. This should also make them aware of this new retail shop coming in their nearby market. Since it is future groups first company that will be launching its retail chain in UAE, it has to take care of the brand image of the Bi-Bazaar from getting tarnished by competitors. Since the retail chain will be starting on such a large scale in UAE it needs to do more and more advertisements in UAE starting from its launch only. Hence we will need following media-mix:  · Billboards  · Banners  · TV program  · Kiosks  · Magazines The method company can plan to make this promotion successful is to have it in various phases. Actually this is one of the most important criteria which company usually follows while entering into a new market. Message Big-Bazaar has the image of providing good quality of items at the rock bottom price. Its image is like everything under one roof. Therefore it has to communicate this image to the consumer showing happy family buying their groceries from a place where every family member got something of his/her choice. Company should communicate this image by stressing its image on tag line which it is going to use while conveying its brand image. Message can be similar to â€Å"Cheaper than this, doesnt exist!!!† Cost Advertisement Newspaper Advertisement $ 20,000.00 AED 73,440.00 Billboard $ 5,000.00 AED 18,360.00 TV Advertisement $ 30,000.00 AED 110,160.00 Kiosk Advertisement $ 10,000.00 AED 36,720.00 Promotion $ 30,000.00 AED 110,160.00 Banners $ 5,000.00 AED 18,360.00 Advertising Expense $ 100,000.00 AED 367,200.00 Sales Promotion Objective The main objective of sales promotion is attracting more consumers in least possible time with a communication that you are offering more value per unit of money to your consumer. In the very first year, company should try making products as much cheaper as it can by bringing small packs or by giving more and more offs on its grocery. Free goodies can be one of the methods to attract more and more consumers towards it. Premiums Premium is generally used in a way in to associate the product with something of real use to customer. Big-Bazaar can use this age old technique by associating some free gifts on spending more than AED 1000 in the in any of the Big-Bazaar retail chain. Coupon Coupons will be some free coupon either of service or of entertainment. This really helps in shoppers incoming into the mall. Big-Bazaar can utilize this technique by attaching coupons with the bill in case the shopper buys more than a threshold limit of goods. Big-Bazaar can offer free movie coupons or next time buyings discount coupon. (Details of Big Bazaars Offer in Festive Seasons â€Å"Big Bazaar Maha Bachat Shopping Discount Independence Day Offer†) Cost Big-Bazaar always cash on low cost model therefore promotion will play a major role here. Company will have to cash in the opportunity of providing more and more goods with the promotional scheme as its very first year and this years performance will work as a make or break for the company. Therefore we have allotted $30000 for the promotional scheme only.

It will not need to sell its product personally but it should have the facility of home-Delivery so that the groceries of higher cost should be delivered safely to consumers home without any damage to create superior experience for consumers. Other Promotional Method No other promotional method should be taken by the company as it is its very first year of operation. It should take traditional method of operation. Distribution from Origin to Destination Mode of Distribution Big-Bazaar will be having products which are of all kinds. It should have its warehouse too in order have extra storage facilities. This warehouse should be optimally located and should be in vicinity to all the 12 stores which are there in the United Arab Emirates. In the very first year of operation company can afford to have two storehouses. There will be staffs working in them and company will be needing one big-bazaar van to commute from store house to store in order to have low empty shelf space time. (Luther, 2011) Packaging Marking and Labeling Regulations Until and unless Big-Bazaar is not launching its own brand product like it sells KOREO in India, it doesnt need to worry about labeling as its general business to sell other brands product at a cheaper price. Containerization Company doesnt need to care for this packaging issue apart from putting RFID on all the products for easy tracking of their availability and presence. The reason is that it will be different brands who are selling under Big-Bazaars brand name that will have to take care of containerization problem. Costs Since packaging is an issue for the brands which are going to sell under the tag of Big-Bazaar here therefore packaging will not be problem for Big-Bazaar. Price Determination Transportation Cost Transportation cost is always there whenever one opens a retail chain. Here the major transportation cost will be there in the movement of goods from warehouse to main retail shops. The transportation should be there in Big-Bazaars own dedicated vehicle. All the transportation cost is there included in Distribution Cost only. The $10000 amount is allotted to it. Handling Expenses Handling expense for product will be borne by company and is included in miscellaneous expense of $4000.

Here we will analyze about how company is planning to expand and what all it will require while expanding in this way. We are going step by step. First we are going to analyze the finances, Personnel and later we will discuss capacity or Scale in which Big-Bazaar should be operating. Finances Companies usually get their finances from two tools Debt or Equity. Debt is the fixed amount taken by company at fixed interest rates. This amount has its maturity associated with and it and after a certain interval of time company has to return. Equity is the money which company usually plans to have through dilution of its ownership. We taking all factors in account thinking about having a PE firm getting associated in financing just by having stake in our firms ownership. We suggests that company should have a debt to Equity ratio of 6:5 in long term and therefore company should invest 45% through its equity and should ask for remaining 55 % as debt from their local banks. Personnel Any firm whenever it starts its business usually needs Personnel to make the ideas take shape. Even the Big-Bazaar will need personnel for its operational requirements. Big-Bazaar will majorly look for following: HR personnel for Customer Care Department Sales Personnel Labors Managers Marketing Personnel Accounting Personnel Operation Personnel Distributor personnel Depending on the scale which we are launching, Companys estimate of personnel for its first year of operation will be as below Marketing 60 Sales 600 Accounting 18 Human Resource 12 Information Technology 5 Operations (including distribution and packaging) 1200 Scale Production capacity should be planned as per companys aim of expanding in future. As per seeing Nestlà ©s trend of expansion plan in other countries, we can assume following as companys capacity requirement in future. Year I 12 Shops Year II 15 Shops Year III 18 shops Year IV 22 Shops Year V 25 Shops Nestle should have production capacity accordingly. Conclusion As we can see from the analysis, Big-Bazaar operation in United Arab Emirates will be profitable only. In the very first year of its operation, The Company can aim to gain a profit of AED 24.6 Million. Companys big brand name and operational expertise can work wonders for the company for its UAE operation. Therefore the verdict is that company should go ahead with its Emirates plan as it seems profitable from the analysis we have made till now.

Do Violent Video Games Cause Aggressive Behavior? :: Media, Violent Video Games

Does playing video games cause aggressive behavior? Because children and teenagers spend an increased amount of time each day playing video games, they are shaping their values, attitudes, and behaviors. For people who do act out aggressively, the results can be deadly. Monthly, the news is filled with blood-chilling accounts of crimes committed due to a copy-cat obsession with violent video games. This paper will present a brief review of literature and reveal the difficulties in answering this question with certainty. For the past 40 years, since the first video games were created, the gaming industry has developed games that would surpass other games before it. Since the late 1970’s, when the first two games of â€Å"Pacman† and â€Å"Space Invaders† were created, video games have changed tremendously over time. The late 1970’s through the 1980’s video game makers used what was called an 8-bit graphic system, which limited many features they could put in video games (Porter & Starcevic, 2007). Violence was not realistic, blood was not red, and so violence in video games was not incorporated into the new games that appeared on the market. In the early 1990’s, video game makers began using a 16-bit graphic system which would enable them to incorporate much more detail of violence and blood into video games. This caused an increase in violent video game demand and an increase in realistic violent events incorporated into these games (Porter & Starcevic , 2007). With technology in video games enhanced, the productivity on violent videos games moved up as well. When a game called ‘Mortal Kombat’ was released in the early 1990’s with a gruesome death seen in the game, the US Congress had to intervene. They told the gaming industry they had to come up with an accurate grading system to rate the games on age-appropriateness and content-appropriateness. This brought on the â€Å"Entertainment Software Rating Board.† While rating each video game and posting that rate on them has improved access by small children, teens and young adults can still buy and view very violent scenes(Porter & Starcevic, 2007). In 2007, there was a tragic event at Virginia Tech University. A young man by the name of Seung Hui Cho went on a rampage on the campus and killed a total of â€Å"32 students and faculty† (Ferguson, 2007).

Revolutionizing Elearning As Young Students Collaboratively Study Education Essay

With the altering life style in the society, how pupils live outside school becomes a challenge in bettering the educational system ; a process that has continuously evolved along with the promotion of scientific discipline and engineering. Gone were the yearss where school was thought to be a mere schoolroom and a instructor to educate immature heads, instead it besides includes modern installations, engineering, course of study and advanced instruction methods. Parents have now more options in taking the sort of instruction to give to their kids. But instruction per Se is besides sometimes defined depending on parents ‘ ability to pay, life style and even work agenda. This research aims to integrate the three factors that affect larning in the kingdom of modern society: the course of study, the method and the electronic platform. While larning system has endlessly been altering, the demand to supply more antiphonal and suiting learning bundle to immature scholars still exists. But are younger coevalss ready to travel for a full-online acquisition? Can you conceive of few old ages from now, school will no longer be schoolrooms but right at our ain place and the used-to be school edifice will be used to ease the face to confront socialisation of the immature scholars? Children will travel to ‘school ‘ to play with other childs and travel place ‘to continue larning ‘ though the aid of larning facilitators who could be parents, professional instructors or coachs and the usage of electronic platforms like computing machine, cyberspace and other engineerings. Learning at place is non a new manner of larning but it began since Renaissance epoch and modern instruction has acknowledged this as an option. One of the options offered by most private establishments is called homeschooling, a authoritative manner of larning but redefined with modified course of study, attack and oftentimes with the integrating of engineering. It is a untraditional manner of larning compared with common schoolroom acquisition, where a parent or coach or professional instructor act as a facilitator-consultant and a scholar stay at place to analyze. This construct was revived in the United States by John Holt ( 1964 ) who felt unhappy with the public school system and subsequently followed by Raymond Moore, a devout Christian and ex-missionary. For most developed states like the United States of America and the United Kingdom, homeschooling is patronized by parents for different grounds. Even for households who migrate abroad seek to happen the best place school for their kids as they still try to settle down or suit in with their working agenda and in the community. Homeschooling, an Alternate There were research surveies on the advantages and disadvantages of homeschooling to turning phase of kids and the socialisation facet is seen to be a common job. This may non be true to all particularly for parents who involve their kids with community activities and other particular involvement categories such as dance category, music, athleticss and others but these would be excess cost. How do most homeschooling ‘teach ‘ pupils at place? There are two types of homeschooling, foremost, parents buy faculties and stuffs and they themselves teach their kids or engage a coach to make it on their behalf ; and 2nd, parents enroll their kids to distance learning plans. Accredited homeschooling establishments have set their criterions to run into their state ‘s regulated course of study instruction as benchmark. Normally, the scholar or pupil takes standardized tests to be measured for an upgrade and/or earn his/her sheepskin. The distant acquisition could take to developing societal accomplishments of scholars. Socialization accomplishments play a important function in the society and if this facet is seen as one of the disadvantages of homeschooling, so possibly, it is non the homeschooling construct that affects the holistic development of kids but the learning procedure and attack. Revolutionizing How Children Learn This research survey focuses on place schooling teaching method in telecollaborative attack utilizing English as medium of direction and e-learning tools in instruction and acquisition. It aims to examine the effects of the said attack in replying the common diagnosed job in homeschooling which is the developing societal larning accomplishments of scholars due to remote or isolated and independent attack in larning. It besides aims to measure whether immature scholars are prepared to full-online larning utilizing engineering as tool while developing their cognitive, socio-affective and psychomotor spheres. Homeschooling in Asiatic States Why English Language? Although the survey focuses on the telecollaborative attack in homeschooling utilizing engineering as tools, English as the map linguistic communication is considered important in developing societal accomplishments as scholars are exposed to planetary practical community. The intense demand brought by the promotion of engineering and globalisation, reenforcing the usage of this linguistic communication has become one of the pushs of the Ministry of Education in many Asiatic states to get by with the altering gait of planetary economic system and learning.A But how long does it take for not native talkers attain English linguistic communication proficiency in academic context? In East Asia, kids learn their native linguistic communication non merely at place but even in schools since about all topics is taught in their native linguistic communication except for English lesson. English is the most studied foreign linguistic communication in the People ‘s Republic of China, Japan , South Korea and Taiwan ( Republic of China ) . In PR China, English is a needed linguistic communication get downing with the 3rd class, although the quality of direction varies greatly and most Chinese citizens do non talk it good. The survey of English is besides required in India, where it is used for official communicating. In Nepal, about all topics are taught in English, except for Nepali literature ( Modern Language, Wikipedia 2007 ) . In the Philippines, English linguistic communication has become the primary medium of direction and required to utilize to non less than 70 % of the clip allocation for all larning countries in all twelvemonth degrees ( Department of Education Order no. 36, Series 2006 ) . Based on the survey in the most successful school learning English as 2nd linguistic communication to pupils in California, the unwritten proficiency takes 3 to 5 old ages to develop, and academic English proficiency can take 4 to 7 old ages ( Hakuta, et.al 2000 ) . An premise was besides made by Epstein ( 1977 ) of Washington Post that linguistic communication acquisition depends on the gait on how English is introduced to a pupil under a bilingual plan. Another in deepness survey of 2nd linguistic communication acquisition was made by Van Lier ( 1998 ) where in his observation he wrote: Many of the early instance surveies of immature kids emphasized the successes of the 2nd linguistic communication acquisition procedure. The research workers frequently marveled at the celerity with which these immature kids learned to discourse in the 2nd linguistic communication, sometimes in a affair of months. These findings concur with the sentiments of the general population that larning linguistic communications is an easy and natural undertaking for immature kids. They merely ‘pick them up, ‘ as it were. However, when we look a little more closely at the inside informations of linguistic communication usage as reported in these instance surveies, we can see a few general forms emerge. In none of the instance surveies, whether of immature kids, striplings or grownups, are any important developments of complex grammar reported within the first twelvemonth, or even in the 2nd twelvemonth. Rather, all surveies speak of formulaic vocalizations, colloquial schemes, and a extremely simple codification. This simple codification is sufficient for mundane societal contact, and frequently gives the feeling of astonishing colloquial eloquence in these contexts, but it is non the elaborate, syntactically and lexically complex codification of the adept linguistic communication user. A A A A A A This gives us an feeling that colloquial proficiency in geting English as 2nd linguistic communication may non compare academic proficiency of the linguistic communication which is the basic kernel for success in formal establishments ( schools ) .A Immersion has been used as scheme in most Asiatic states like China, Korea, Japan, Malaysia Thailand and few selected metropoliss in the Philippines. However, the fact that one develops colloquial linguistic communication accomplishments, it still helps in set uping resonance as one builds societal web.Theoretical BackgroundTelecollaborative Approach refers to the method applied in the instructional design that involves scholars working with their equals in the schoolroom and with equals at a distance through on line or practical coaction. Telecollaborative came from two blended words: Tele means â€Å" at a distance † and Collaborate means â€Å" portion the labours † ( literally, â€Å" co-labor † ) ; â €Å" tele-collaborative † is a larning undertaking in which the participants â€Å" portion the labours † of larning â€Å" at a distance † through the assistance of information and communicating technology.A They may portion those labours through electronic mail, newsgroups, treatment forums or a figure of other online tools and larning environments. A A A A A A This instructional design is anchored on different larning theories, rules and surveies. A A A A A A Constructive Pedagogy is an attack based on premise that cognition is developed ( constructed ) by the person through actively take parting in the cognitive procedure, societal procedure and rational procedure. It, promotes a more open-ended acquisition experience where the methods and consequences of larning are non easy measured and may non be the same for each scholar ( Mergel, 1998 ) . Harmonizing to Smorgansboard ( 1997 ) , as influenced by other theoreticians like Bruner, Ulrick, Neiser, Goodman, Kant, Kuhn, Dewey, Habermas, and Jean Piaget, Constructivism creates real-world environment that employ the context in which acquisition is relevant ; focal points on realistic attacks to work outing real-world jobs ; provides tools and environments that help scholars construe the multiple positions of the universe ; displacements paradigm of the teacher to a manager and analyser of the schemes used to work out jobs ; stresses conceptual interrelation by supplying multiple representations or positions on the content ; negotiates and non imposes instructional ends and aims ; utilizes rating as a self-analysis tool ; and makes larning internally controlled and meditated by the learner.A A A A A A A Another larning theory aligned to constructivism is David Kolb ‘s theory known as Experiential Learning, foremost published in 1984 when his thoughts have had a dramatic impact on the design and development of womb-to-tomb larning models.A Harmonizing to his theory, experience is the beginning of larning. Kolb and Fry ( 1983 ) created celebrated theoretical account out of four elements: a. ) concrete experience, B. ) observation c. ) contemplation, and d. ) program, the formation of abstract constructs and proving in new state of affairss. The celebrated experiential larning circle patterned after Kurt Lewin ‘s, explores the cyclical form of all larning from Experience through Reflection and Conceptualizing to Action and on to AA farther Experience.A A A A A A A The 3rd theory considered by the research worker is Judith Harris ‘ Learning Framework. Harris ( 1998 ) is noted for her seminal activities in telecomputing where schoolrooms are connected worldwide through the assistance of internet entree. The activity constructions are interpersonal exchanges, information aggregation and job resolution. The research worker adopted the learning model of Judi Harris to enable scholars to associate with state of affairss within and outside their ain context, to pass on and to associate outside the schoolroom through the assistance of information and communicating engineering. A A A A Two surveies conducted were found to hold used one or two of the mentioned theories such as constructivism, experiential theories and telecomputing framework.A These involved different schemes in learning linguistic communication both in primary and in secondary schools.A Most of these schemes used engineering in learning particularly in developed states like United States of America and Europe. A A A Apple Classroom of Tomorrow ( ACOT ) of United States of America and Project Method in School Projects through E-Learning ( PROMISE ) of Europe conducted a separate survey about effectual schemes in learning English linguistic communication. A A A Harmonizing to the research conducted by Apple Classroom of Tomorrow ( ACOT, 1998 ) , the cardinal accomplishments of reading, authorship, and arithmetic remain the basiss of schooling and pupil acquisition. Surveies have shown that pupils with everyday entree to engineering larn these basic accomplishments faster and better when they have a opportunity to pattern them utilizing engineering and are more motivated to larn when engineering is portion of their day-to-day school experience. Surveies show that one time pupils become familiar with engineering, they rapidly develop proficiency in its usage. This opens up an exciting new universe of larning possibilities for them, and their possible for achievement skyrockets. Students gain new accomplishments and go familiar with new engineerings that will assist fix them for future success in an progressively technological universe. Even the most basic tools can assist immature scholars become more productive. A A A Researchers involved in the Apple Classrooms of Tomorrow undertaking revealed that third-grade pupils found it easier to compose with a keyboard than with a pencil or a pen. Because authorship was easier, they wrote more. By composing more, they learned to compose better. Their battle to larning undertakings with engineering led them to this betterment. As a consequence, they spend more clip acquisition and practising the basic undertakings than pupils who approach the same undertakings in a traditional paper-and-pencil mode. A A A A A A In Europe, K. Antilla, M.A Erickson and S. Holme-Larsen conducted Project Method in School Projects through E-Learning ( PROMISE, 2005 ) .A They found out that many of the participants of the computing machine supported job based acquisition were positive about the technological attack. They said that the pupils love to make computing machine supported collaborative undertaking work because it was different from how they usually work.A The merchandise orientation was non what attracted the kids, but the procedure of larning on how to happen information and how to make the research.A However, the troubles on the lingual and cultural facets of communicating with aliens were the important barriers on this project.A Many respondents found that the deficiency of personal lingual competency was a heavy barrier, whereas professional educational facets such as instruction, acquisition, pupils ‘ function in the schoolroom pattern less of import. Several participants declare that their over all feeling was that their pupils were happy to take part in multinational computing machine supported collaborative acquisition ( CSCL ) undertakings. They considered it as a benefit and gave new inspiration to instructors and pupils who were involved in such undertakings. A A A A A A Both ACOT and PROMISE stated that engineering played as an of import subscriber in learning scholars to compose, read and even work with equals. However, what were emphasized were non the technological facets entirely but the procedure involved utilizing engineering as tools in learning pupils made them execute better.A Although diverseness in linguistic communication, civilization, and deficiency of engineering tools in some countries became barriers in Europe, still the acquisition undertakings were found to be good. A A A A A A The 4th theory considered for this survey was Mc Grath ‘s Mentoring Framework, a model that directs wise man or the instructor to take the propositional cognition of the mentees or the pupils to procedural cognition through providing, taking or demoing. It process scholars to go brooding practicians of cognition. The terminal end of this model is to do scholars skilled in using their acquisition at the terminal of the procedure. This model was adopted in the National English Proficiency Program of Department of Education in 2003. It was a mentoring plan designed for instructors to better their presentation and treatment accomplishments, art of oppugning and giving of undertaking instructions accomplishments. A A A A A A The last theory considered and found to be the baseline of the theoretical model is the Social Network Theory where a map of all of the relevant ties between the nodes is being studied ( Barnes, 1954 ) .A This theory refuted the traditional sociological surveies where single attributes matter more than the relationship. Alternatively it was the antonym, where relationship ties matter most and where single attributes affair less ( Burkhardt, 1994 ) .A A A A A A A With the promotion of engineering, societal networking engineerings play an of import portion in pupil motive, keeping and learning-especially in distributed acquisition environments. Social networking engineerings and media are of import tools because of their ability to further interaction and communicating between pupils. This is particularly of import in on-line acquisition communities, where pupils may hold limited face-to-face clip to construct a support web with their equals ( Baird, 2005 ) and homeschooling is one of the authoritative illustrations. A A A A A A Derek Baird wrote that a cardinal component of a societal web engineering like Flickr was its uniqueness on its platform design.A Online coaction and community are interwoven as chief constituents. Though it was non originally designed for instruction, it was found to be utile. Baird said that one of the chief booby traps of presenting new engineering into the schoolroom ( on-line or otherwise ) is the hazard of holding the engineering frustrate the user to the point that it distracts them from their original acquisition end. Apec Cyber Academy Program, Taking IT Global, ejournals and other educational online site are some illustration of societal web tools that areA of import because their ease-of-use allows the pupil to maintain his/her focal point on geting new accomplishments, constructing on bing cognition while at the same clip developing authorship, package, and beef uping societal ties within their learning circle. A A A A A A An application of societal web theory was studied by Kern, R. and Warschauer, M. ( 2000 ) where they presented the development of linguistic communication learning utilizing computing machine. In their paper, they presented the theories behind the computing machine assisted linguistic communication acquisition ( CALL ) and the development of network-based linguistic communication instruction ( NBLT ) as one signifier of CALL.A Harmonizing to the writers, NBLT is linguistic communication learning that involves the usage of computing machines connected to one another in either local or planetary webs. Whereas CALL has traditionally been associated with self-contained, programmed applications such as tutorials, drills, simulations, instructional games, trials, and so on. It represents a new and different side of CALL, where human-to-human communicating is the focal point. Language scholars with entree to the Internet, for illustration, can now potentially communicate with na tive talkers ( or other linguistic communication scholars ) all over the universe 24 hours a twenty-four hours, seven yearss a hebdomad, from school, place, or work. Learners can pass on either on a one-to-one or a many-to-many footing in local-area web conferences and farther multiplies their chances for communicative pattern. Finally, the fact that computer-mediated communicating occurs in a written, electronically-archived signifier gives pupils extra chances to be after their discourse and to detect and reflect on linguistic communication usage in the messages they compose and read. A A A A A A However, still instructors remained disbelieving in the usage of this scheme ( Cotton, 1995 ) . As footing, few research surveies have been conducted as to computing machine and linguistic communication acquisition. Some illustration of this was the academic study of instructional usage of engineering in 1995. It showed that 59 % of foreign linguistic communication plans and 65 % of ESL plans used no signifier of computing machine engineering in their classs and puting linguistic communication instruction at the underside of the list of academic countries surveyed. A A A A A A In this survey, the reappraisal of NBLT of Carla Meskill ‘s and Krassimira Ranglova ‘s research ( 2000 ) on the execution of new technology-enhanced English as Foreign Language ( EFL ) instruction in Bulgaria was cited. Meskill and Ranglova showed that the usage of computing machine webs was portion of a broader conceptualisation of the linguistic communication plan that resulted in a more â€Å" socio-collaborative † attack to acquisition, a greatest illustration of the fact that engineering is non merely a machine, or even merely the usage of a machine, but instead a wide signifier of societal organisation. Part of the reappraisal is the sum-up of findings on how engineering, content affair, and activities were integrated in the literature-based course of study through the usage of audio tape, harmony plans and manner draughtss, word processing, and email coactions. In their findings, pupils under NBLT significantly gained higher in reading, vocabular y, grammar and authorship. A A A A A A Teachers reported that the new course of study required pupils and instructors likewise to radically change their apprehension of what it is to larn a linguistic communication. Because of the cardinal displacement in position required by the new course of study, teachers reported an initial daze followed by gradual and favourable accommodation to this new independent and participatory manner of larning. Likewise, instructors felt their ain accommodation experience, though ab initio rather hard, eased by the instantly discernable benefits reaped by their pupils. A A A A A A Students reported a really enthusiastic response to the new course of study. They reported this â€Å" response-based † attack to literature affecting email exchanges with American university pupils to be highly helpful in footings of motive, assurance, and overall English linguistic communication development. Interestingly, though non alone in the literature, merely half of the pupils found the equal redacting component of the course of study helpful. A A A A A A Cited surveies provided grounds for the viability of computing machine engineerings as tools to back up linguistic communication larning ends and the socio-collaborative procedure. It is believed that through these theories, Constructivism, Experiential Learning, Telecomputing, Mentoring Frameworks and Social Network Theory, scholars in Asia under homeschooling plan would go socially adjusted and academically developed as other pupils in a regular school plans.Research AimsThis research aims to examine the followers: Readiness of immature scholars for full-on-line acquisition Effectiveness of telecollaborative attack in advancing critical, brooding and societal accomplishments Effectiveness and functionality of the e-platformsSignificance of the StudyTechnology has been portion of our turning modern society. Using it to the full benefits of every citizen begins with the right instruction that we provide to our younger coevals. How we gear them to take our future civilisation is every bit important as gestating the appropriate acquisition teaching method and tools that pedagogues use before really implementing it in the acquisition procedure. Hence, this survey considers the possible important effects of full online larning through homeschooling plans and prepares responsible stakeholders for its possible effects to avoid any inauspicious possibilities from repeating in the hereafter.Research MethodologyA A A A A A The research worker will utilize Experimental and Qualitative Research as methods.

Camelina: a Market Forecast and Strategy Report

Camelina: a Market Forecast and Strategy Report 40 graphs and charts Camelina: a Market Forecast and Strategy Report 40 graphs and charts Published March 2010 From Biomass Advisors, a Biofuels Digest company Camelina has been much in the news of late, as a biofuels feedstock of strong promise, because of its position as one of the few â€Å"sustainable, affordable, reliable, available† feedstocks suitable for aviation biofuels. In November, KLM Royal Dutch Airlines made the first biofuels test flight with passengers on board, powering one engine with a mixture containing biofuel made from Camelina. Great Plains – The Camelina Company provided some of the Camelina used to make the fuel for this flight. Earlier, camelina was one of the feedstocks powering the Japan Airlines biofuels test, while the U. S. military has performed ground engine tests on camelina-based jet fuel in preparation for FA-18 Hornet fighter jet flights planned for this spring. Biofuels Digest has covered the camelina story in 71 different stories since 2007. But what’s the bottom line, for the grower, processor, end user, investor or policymaker? Biomass Advisors — a Biofuels Digest company focused on in-depth research — will release its definitive report on camelina in March 2010, including 40 charts and graphs. It’s based on unparalleled access to and cooperation with key stakeholders, on trends in processing, yields, geographies, and the end user markets opening up for high-value animal feed, and liquid transportation fuels (including aviation biofuels). In the report you’ll find the timeliness and perspective expected of the Digest — but with far more depth than a daily newsletter can provide.

Sex appeal as a marketing strategy

Sex appeal as a marketing strategy Does sex appeal sell? The use of explicit sexual imagery has become a common marketing strategy for many organizations in the recent years. Companies have realized the power of this strategy in marketing products and services. Today, sex appeal is more prominent than ever before. There are several things that connect sex appeal marketing strategy to consumer behavior.Advertising We will write a custom essay sample on Sex appeal as a marketing strategy specifically for you for only $16.05 $11/page Learn More Using sexual appeal to promote a product or service is not a new concept. Over the last two decades, many organizations have been and are still experiencing effectiveness of sex appeal in marketing products and services. For instance, a study about marketing appeals in 1996 found that sex component is one of the strongest physiological means (Taflinger, 2012, p. 1). Biologically, it is the desire to get a mate of one’s choice. In reference to Pelsm acker, Geuens Bergh (2013), advertising and marketing research firms confirmed that sex appeal marketing strategy is one of the best techniques of communicating with target audiences (Pelsmacker, Geuens Bergh, 2013, p. 211). There are many reasons that make sex appeal sell, or that make marketers turn to it when selling their products or services. To start with, sex appeal helps companies grab attention of customers. These adverts attract both male and female customers. It grabs their attention by taking focus from other things, which they may be doing. Marketers know this. They understand that this appeal is more likely to make a product or service appealing in the mind of consumers, more than any other appeal. A good example of sex appeal targeting men is the launch of Heineken in 2000. The company developed a promotional campaign in which it integrated sex appeal and managed to increase its sales by 13% within a short period of time (World Forum of Sociology, Pirani Varga, 201 0, p. 133). Marketers also use sex appeal strategy in order to the images of the brand in the consumers’ minds (Heller, 2000, p. 142). After watching sexual and shocking advert, consumers are likely to recall the advert at all times especially when a need arises. They are likely to share information with their friends leading to wide information coverage. Sex appeal marketing strategy engages and entertains target audience, particularly when presenting fantasy elements. This causes them to buy marketers’ products and services. Contrary to this, some people may argue that sexual appeal is not a decent form of advertising. For instance, religious conservatives view it as immodest, and feminists claim that it causes sexism. However, this is not the case. Sex appeal marketing strategy is only used to market products and services.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Those who perceive it negatively are in most cases guided by fallacies that do not exist. They may also be naà ¯ve in terms of marketing businesses. Many research studies indicate that businesses that use sex appeal marketing strategy are more likely to succeed in increasing their sales and profit than those that do not. Despite the aforementioned counter argument, I am of the opinion that sex appeal sells. Most of today businesses, which integrate sex appeal marketing strategy, do better than those that use other forms of appeals. This marketing strategy should be adopted by businesses that intend on catching the attention of consumers. They should use it to promote their products and services. The main purposes of sex appeal marketing strategy include stimulating, arousing, and gathering consumers’ attention towards products and services advertised by marketers. Marketers should use this strategy in accordance with law, by ensuring that they do not influence people to get involved in illegal activities such as pornography and violence among other things. They should instead use it for the purposes of service or product promotions, in satisfying customers’ needs profitably.

The world Trade Organization (WTO) The WritePass Journal

The world Trade Organization (WTO) Introduction The world Trade Organization (WTO) IntroductionWTO and Trade Libralization:The Doha Development Agenda:Competitive Environment:References:Related Introduction WTO and Trade Libralization: â€Å"The world Trade Organization (WTO), is the only global international organization monitoring and controlling the rules of trade between nations. It was formed in 1995 with the General Agreement of Trade and Traiffs (GATT) as its basis.† (Paul and Aserkar, 2010:1) The Doha Development Agenda: The fourth ministerial conference in Doha, in its November 2001 declaration, highlights the directives of negotiations around 21 subjects and the problems faced in their execution. The declarations support the WTO agreement objectives in order to amend the restrictions and biases in the world agriculture markets. (wto.org/english/tratop_e/dda_e/dohaexplained_e.htm#subsidies) The member countries are entitled to focus on the following facts: Access to Market Subsidies on Export Reduction in domestic support. For developing countries like Africa and Latin America, the Doha Declaration provides a differential treatment during the negotiations with some special provisions to monitor if the countries meet with the basic needs like food security and overall development. Competitive Environment: â€Å"No prohibitions or restrictions other than duties and taxes whether made effective through quotas, import or export licences or other measures, shall be instituted or maintained by any contracting country on the importation of any product of any other member country.† (GATT 1947) According to the original GATT, introduction of non-tariff barriers such as subsides and import quotas, creates an unfair environment, highly distorting the agricultural trade especially with the use of export subsidies. (wto.org/english/tratop_e/dda_e/dohaexplained_e.htm#subsidies) The Multilateral Agreement in the agriculture sector produced in the Uruguay Round laid the foundation to a fair competition with minimum distortions, through constant restructuring in the negotiations. (wto.org/english/tratop_e/agric_e/agric_e.htm) Africa and Latin America have predominantly large population especially in the rural areas, wherein the prime focus of these groups is agriculture. As per the FAO 2000 reports, agriculture occupies 50 percent and 20 percent of the total employment in the African and Latin American countries.   (Morrison and Sarris, 2007: 340) The European Union and The United States trade polices play a major role in promoting the overall progress of the developing nations by providing adequate support in accordance to the WTO agreements. No doubt that, agricultural products occupy a major share in exports of the developing countries. The United States and European Union impose higher controls on the agricultural exports of these developing nations by excising or imposing subsidies. However it would be quite unfair on their part, just to focus on either Africa or Latin America or only on the agricultural products and no other major industries or sectors. Moreover they are not legally obliged to focus on the concerns of other countries for their own benefits. In this competitive world, the big players should promote equal opportunities for all the countries, especially the developing ones. The core sectors need to be classified and equally promoted for a balanced overall growth. As in most developing countries, the rules and procedures of the multilateral trading system are regarded as unfair by the developing countries. They view the rules and procedures as favouring the developed countries. For example, although the WTO is supposed to be a member-driven organization, important issues and decisions are taken in â€Å"Green Room† meetings and African countries do not have proportionate and adequate representation at these meetings. In addition, because of their relatively low bargaining power, countries in the region have difficulties setting and influencing the agenda and pace of negotiations. The lop-sided power structure of the multilateral trading system is evident in the fact that developed countries managed to get the Singapore Issues on the agenda of the Doha Work Programme at the WTO Ministerial Conference in Doha despite mounting opposition from developing countries, who comprise more than two-thirds of the membership of the WTO. The Singapor e Issues contributed to the failure of the 2003 WTO Ministerial Conference in Cancun and three of the four issues were eventually taken out of the Doha Agenda. (Morrison and Sarris, 2007: 344-345) To stabilize farmers’ incomes and preserve a practical, diverse agricultural system is by combining the supply management and the price supports. In order to be effective, The United States and European Union should impose superior tariff controls along with the price supports on the imported farm goods. However such a policy prescription, of course, runs completely counter to the entire neoliberal thrust of the last twenty-five years, and would effectively remove US farm policy from the regulatory jurisdiction of the WTO, signalling the end of the WTO’s Agreement on Agriculture.

Pre-Pottery Neolithic - Farms and Feasts Before Pottery

Pre-Pottery Neolithic - Farms and Feasts Before Pottery The Pre-Pottery Neolithic (abbreviated PPN and often spelled as PrePottery Neolithic) is the name given to the people who domesticated the earliest plants and lived in farming communities in the Levant and Near East. The PPN culture contained most of the attributes we think of Neolithicexcept pottery, which was not used in the Levant until ca. 5500 BC. The designations PPNA and PPNB (for Pre-Pottery Neolithic A and so forth) were first developed by Kathleen Kenyon to use at the complex excavations at Jericho, which is probably the best known PPN site. PPNC, referring to the terminal Early Neolithic was first identified at Ain Ghazal by Gary O. Rollefson. Pre-Pottery Neolithic Chronology PPNA (ca 10,500 to 9,500 BP) Jericho, Netiv Hagdud, Nahul Oren, Gesher, Dhar, Jerf al Ahmar, Abu Hureyra, Gà ¶bekli Tepe, Chogha Golan, BeidhaPPNB (ca 9,500 to 8200 BP) Abu Hureyra, Ain Ghazal, Çatalhà ¶yà ¼k, Cayà ¶nà ¼ Tepesi, Jericho, Shillourokambos, Chogha Golan, Gobekli Tepe PPNC (ca 8200 to 7500 BP) Hagoshrim, Ain Ghazal PPN Rituals Ritual behavior during the Pre-Pottery Neolithic is quite remarkable, indicated by the presence of large human figurines at sites such as Ain Ghazal, and plastered skulls at Ain Ghazal, Jericho, Beisomoun and Kfar HaHoresh. A plastered skull was made by modeling a plaster replica of skin and features onto a human skull. In some cases, cowry shells were used for eyes, and sometimes they were painted using cinnabar or other iron-rich elements. Monumental architecturelarge buildings constructed by the community for use as gathering spaces for those communities and allied peoplehad its very first beginnings in the PPN, at sites such as  Nevali Çori and Hallan Çemi; hunter-gatherers of the PPN also constructed the significant site of  Ã¢â‚¬â€¹Gà ¶bekli Tepe, an apparently nonresidential structure built for ritual gathering purposes. Crops of the Pre-Pottery Neolithic Crops domesticated during the PPN include the founder crops: the cereals (einkorn and emmer wheat and barley), the pulses (lentil, pea, bitter vetch, and chickpea), and a fiber crop (flax). Domesticated forms of these crops have been excavated at sites such as Abu Hureyra, Cafer Hà ¼yà ¼k, Cayà ¶nà ¼ and Nevali Çori. In addition, the sites of Gilgal and Netiv Hagdud have produced some evidence supporting the domestication of fig trees during the PPNA. Animals domesticated during the PPNB include sheep, goats, and possibly  cattle. Domestication as a Collaborative Process? A recent study at the site of Chogha Golan in Iran (Riehl, Zeidi and Conard 2013) has provided information concerning the apparently wide-spread and perhaps collaborative nature of the domestication process. Based on the exception preservation of the botanical remains, the researchers were able to compare the Chogha Golan assemblage to other PPN sites from all over the Fertile Crescent and extending into Turkey, Israel and Cyprus, and have concluded that there might very well have been inter-regional information and crop flow, which might account for the nearly simultaneous invention of agriculture in the region. In particular, they note that crop domestication of seed plants (such as emmer and einkorn wheat  and barley) seems to have arisen throughout the region at the same time, leading the Tà ¼bingen-Iranian Stone Age Research Project (TISARP) to conclude that inter-regional information flow must have occurred.

Molecules and Processes of Life Activity 6 - Cellular Respiration and Lab Report - 1

Molecules and Processes of Life Activity 6 - Cellular Respiration and the Effects of Pollutants on Its Rate - Lab Report Example s carried out using yeast and the focus of the experiment was given to the amount of gas that was being produced to determine amount of carbon dioxide in the produced gas. The gases are produced after the yeast cells carry out respiration. The experiment looked at how carbohydrates affect respiration that occurs in cells. This was investigated by addition of sugar to the yeast after the first test was carried out. The addition was aimed at production of more gas especially carbon dioxide which determined that the rate increased in cellular respiration. Pollutants in the experiment were expected to have an effect on the cellular rate of transpiration (Audesirk, Audesirk & Byers, 2006). More different pollutants were added to the yeast and the amount of carbon dioxide that was produced measured to determine the effect of the pollutants on cellular rate of transpiration. The main aim of the experiment was to determine the role of cellular respiration in the processes of life. Respiration in cells is defined as the course of energy from chemical in food is obtained and then converted to an energy form that can be utilized by living organisms in the course of living. The objectives of the experiment were to determine how the rate of cellular respiration is affected by the incidence of carbohydrates and also whether the rate was affected by pollutants (Jà ¸rgensen & Fath, 2008). Hypothesis of the experiment was that an organism will be exposed to a higher rate of cellular respiration with availability of carbohydrate than when there is no carbohydrate. Another hypothesis was that an organism will have a lower rate of cellular respiration with a source of carbohydrate and a  pollutant than when there is a source of carbohydrate and without source of pollutant. The pollutants are thought to play a role in interruptions that occur in cellular respirati on. There are two types of cellular respiration which both depend on energy. The two types of respiration include aerobic

For instance, Oprah Winfrey is one of the most renowned talk show host, producer, director amongst many other things, alongside playing an active role in politics. Similarly, Kenneth Frazier owns a pharmaceutical company while Ursula Burns is the CEO of Xerox. Similarly, many entrepreneurs like Roberts brothers are making a name in hospitality industry with various other black billionaires indulged in a multitude of businesses. Therefore, black billionaires aren’t dominating in a single field, rather their scope of engagement in context to business is expanding by the day. This implies that the number of African Americans seeking a higher educational status is increasing and thus, the business practices would now have to be shaped in such a way that African Ameri cans also get a fair share of inclusion. In other

What are Some Main Problems the U.S. Faced during Reconstruction Assignment

What are Some Main Problems the U.S. Faced during Reconstruction - Assignment Example The whites were not ready to treat Africans as equals; they, therefore, went ahead to form groups like the famous Ku Klux Clan among others. These groups were used to threaten blacks, warn them not to vote, and later on turned violent on them. This kind of treatment was an indication that the whites in the south were not ready to live with blacks. They, therefore, came up with a law that allowed segregation (Stampp, 136). The federal government had to craft ways of dealing with this problem by setting up Freedmen`s Bureau to support blacks escaping from the south. Abraham Lincoln`s plan to pardon the southern states which seceded was opposed by Congress, who wanted these nations to be punished. The idea behind his plan was that these nations were to be pardoned if they took an oath of allegiance to the United States and if they also create a new government that guaranteed the end of the slave trade. After the assassination of Abraham Lincoln, a group in the Congress known as Radicals Republicans did not allow the southern senators and representatives to join the Congress (Stampp, 301). And they also came up with their own reconstruction act that made it difficult for these nations to be accepted back to the Congress. The compromise of 1877 did not just bring reconstruction to an end, but it also birthed many things. The first of which was to allow Hayes who was a Republican become president, this was also a way that was used to solved elections dispute and also allowed the withdrawal of the remaining federal troops from the south (Stampp, 217). And after Hayes was sworn in as the 19th president of the United States, he immediately ordered the remaining federal troops to be withdrawn from South Carolina and Louisiana. Hayes also came up with plans for election reforms and committed himself to bring the differences between the North and South to an end. Afterward, the Democratic Party was given freedom in the South. Even though many people look at the compromise as a positive thing, the former slaves did no, to them this decision was taking them back to slavery. This is because during reconstruction they became free and also attained both social and political rights.  

To what extent does Channel Four continue to fulfil its original remit Essay

To what extent does Channel Four continue to fulfil its original remit Is that remit still relevant in the current broadcasting environment - Essay Example The recent reality show of the Big Brother has been a huge hit among the viewers of the UK. From its humble beginnings, the channel has matured to one of the most popular channels in the UK. In 1995, Brookside attracted nine million viewers. â€Å"Four Weddings and a Funeral† drew eleven million viewers. These programs have been an integral part of the success of the channel. The channel has been following its remit in the broadcast of its programs. The remit of the company as stated in its website is as follows: â€Å"Foster the new and experimental in television.   It will encourage pluralism, provide a favored place for the untried and encourage innovation in style content perspective and talent on and off screen†. (Twenty years of Channel 4; Statement of promises). Throughout its history, the channel has been introducing programs that have been hardly viewed by the people of the UK earlier. The remit of the channel has been to introduce innovation in the programs in the channel. The channel has a full repertoire of programs ranging from drama, films, comedy, documentaries etc. Channel 4 has covered almost all the genres of entertainment. The channel has been targeting the youth with its programs, which has been attacked by Sir Jeremy Isaacs, the founder of the channel. In his words, "To target and reach a demographically clearly defined audience - the 18-35 year-olds - and single-mindedly commission a bulk of programmes that suits their tastes, however laddish or yobbish." (Twenty years of Channel 4) The choice of the programs in the case of the channel has been increasingly linked to the needs of the younger generation. The use of the adultery, sex etc. in the programs has been popular. This has been seen in the case of all the genres of the programs. In the case of comedy, the programs like â€Å"Balls of Steel† have a rich content of adult humor. The program

Case study - Essay Example Even if he was aware of the contract it is still possible that he was not aware of the clause. The fact that management made them aware of the presence of these people and they still went ahead with their holiday could lessen their chances at raising a claim against the hotel or the travel agency. This goes into their complaint about the poor food. It must be established whether or not the poor quality of the food was a function of an unsupported expectation or because it failed to meet conditions set forth in a contract. ‘Quiet atmosphere’ was an essential requisite of the client before he agreed to book with Elite. If it can be shown that Elysium acted in wanton disregard of this fact, a case can be made that they acted in bad faith because they knowingly booked Mr. Williams in the hotel knowing that he would be in the company of the 18-30 club people when he wanted peace and quiet. This goes into their claim that it was impossible for the hotel to accommodate his desire to be away from the noisy young people. If it can be shown that there were vacancies in the hotel and Mr. Williams knew about this, then there is a further showing of bad faith. My client Mr. Williams has a complaint that amounts to a breach of contract on the part of Elysium and Elite Travel. At issue here is that Mr. Williams reserved a two week vacation at Elysium based on the offer made by Elite Travel which promised certain conditions which were not met. Among the conditions breached was the offer of international cuisine and an Olympic size swimming pool. The cuisine was described by Mr. Williams as â€Å"junk food† and the Olympic-size swimming pool was always closed because the 18-30 Club patrons kept rendering it unusable. The attitude of management at Elysium further aggravated Mr. Williams because the resort was unwilling to accommodate his

The primate pattern Essay Example | Topics and Well Written Essays - 500 words

The primate pattern - Essay Example There are various hypotheses that attempt to explicate the original evolutionary divergence of the privates but the three hypotheses are the main in the evolutionary process. The Arboreal Hypothesis was advanced by the Elliot Smith and was later supported by Wood Jones. The Elliot Smith hypothesized that the ancient primates were terrestrial animals that at the end came to dwell in arboreal habitant because of the selective pressure divergent from their original terrestrial way of life (Srivastava 18). In the arboreal environments, the primate vision and the sense of touch became greater senses compared to the sense of smell that led to developing new methods of adaptation essential in the arboreal settings. The functional arboreal hypothesis lacked supportive and clear evidence to explain how primate adapted their terrestrial style into the arboreal environment; therefore, criticism led to evolution of other alternative hypotheses. Cartmill introduced alternative hypothesis called Visual Predation that would explicate the progression of primates. He demonstrated that the morphological pattern of the primates do not indicate arboreal adaption as shown by Smith, rather adaptation to feeding mode to bushy forest in the ground where they hunted for fruits and insects. Therefore, it is clear that little primitive, mainly insectivorous and ancient primate were capable to reach for the branches using their prehensile limbs and catch prey with a forelimb while judging the way with close-set eyes (Ravosa and Dagosto 12). Consequently, it is comprehensible from that ancient primate relied deeply on the sense of vision that why the theory is known as visual predation hypothesis. Similar to the first hypothesis, the Cartmill hypothesis was criticized because it was yet to be proven and the primate pre-adapted for the arboreal living. However, it is harmless to point out that the arboreal and visual predations are not mutu ally exclusive

Crisis management Essay Example | Topics and Well Written Essays - 1250 words

Crisis management - Essay Example While some crisis as the Cuban missile crisis was resolved within a period of 13days, others such as the World War I took over 4 years before they were finally settled. This essay seeks to evaluate the success factors of conflict resolution and analyze how they were applied in the Cuban missile crisis and the World War I. Kouzmin (17) points out that the timeliness of the response is a critical factor that determines the ability of the government or the involved parties to resolve their conflict. Crises are emergency situations that often have adverse effects to the social political system if prompt actions are not taken. The more the time that is taken to resolve a conflict, the more likely that the impact of the war is likely to be felt in the affected regions. While it is important to define a good background to resolve a conflict and to avoid hurried decisions that may fuel the war, there is need to develop a quick plan to initiate resolution strategies to reduce the ill effects that come along with such situations of war. Caldwell (6), a professor and a political analyst, commends President Kennedy for his prompt action to neutralize the looming danger of a heated nuclear war in a time of emergency. When the Cuban president stationed missiles in Cuba, there was already high tension that the two countries would engage in big fights whose repercussions would be out of magnitude. At this time, President of America prioritized this issue and focused on the emergency situation. First, he immediately dropped his support for North Korea attack on South Korea and engaged a consultative meeting to come up with a plan to resolve the conflict. Consequently the conflict was resolved within 13 days and no impacts of the looming war were experienced in America. Crisis management in the World War I seems to have taken a slow pace. Mulligan (73) points out that the reason why this war took too long to solve is because the governments had an attitude that any attempts to l aunch a crisis management plan would be futile. The impact of this delay is that World War I became one of the most catastrophic crises in the world history as many people lost their lives. The magnitude of the crisis is a factor that cannot be ignored while designing a strategic plan to mitigate the effects of a crisis. The geographical scope of a disaster is used to measure the intensity of a crisis and the population that is likely to be affected by the effects of the conflict. A disaster that involves only a few countries has less impact compared to one that affects the entire world. While planning the conflict resolution strategy, it is important to consider the applicability of the strategy to all the nations especially in a conflict that spans out in several countries. Kouzmin (7) warns that the domain of the threat has to be considered if the intervention strategy has to be successful. The First World War was a worldwide disaster the war was manifested in different ways in v arious countries. Mulligan (227) states that this war was a result of various threatening forces and determining the motives of the war was quite a complex issue, a factor that delayed the process of peace making. Governments took longer to agree on the best procedure to conflict resolution and this slowed the process while more people continued to suffer

GSM Implementation

GSM Implementation GSM Implementation in various places Transaction terminals: SMS messaging can be used by machines like the EDC, POS terminals to conform transaction from the main server. Supply Chain Management: The GSM M2M technology can be used to fulfil the needs of SCMs huge IT infrastructures with leased lines, data centre, workstations. Multiple Remote Data Collection Points: With the help of the GSM modem connected to PCs, GSM electronic terminals PCs one can send and receive data from all over the world. This help client to receive data from branch offices, business associates, warehouses, and Mobile phones. Large Transaction Volumes: GSM SMS messaging is capable of handling large number of transaction data in a very small period of time as it can receive large number of messages on your server without internet connectivity. With the help of GSM at a time the shopkeeper can handle hundreds of transaction. High Uptime: GSM mobile network have high uptime as compared to other communication networks so it helps business. It can be used in communication industries as it doesnt require any kind of wires for setting up the network so there is no fear of cutting of wires. Implementation of GSM Technology There are three main parts of the GSM Network * Mobile Station (MS):-The subscriber carries out this part. * Base Station Subsystem (BSS) :- It controls radio link with mobile station. * Network and Switching Subsystem (NSS):- This part keeps track of the call switching between two mobiles and also looks over Memory management and also between fixed network users and mobile. Network structure All of the elements when combined together produce many GSM services such as voice calls and SMS. Mobile Station Consists of: * Mobile Equipment (ME):- These consist of equipment such as hand portable and vehicle mounted unit * Subscriber Identity Module (SIM):- It is a chip size object which contains the information about the user like its identification, secret keys. The BSS In the above diagram the Base Station Subsystem (BSS) is shown containing the Base Station Controller (BSC) and the Base Transceiver Station (BTS) which are connected together on to A-bis interface. The Packet Control Unit (PCU) is also shown connected to the BTS although the exact position of this depends on the vendors architecture. The Air Interface or Um is used to connect the mobile to the BSS which is connected by the A interface to the NSS. The NSS The Network and Switching Subsystem(NSS)comprises of the MSC connected via the SS7 network to the HLR. The AUC and EIR, although function differently from the HLR are shown together as combining them is a standard in all Vendors networks. The NSS is connected by the A interface to the BSS. It is directly connected to the PSTN from the MSC. There is also a connection to the Packet Core (called the Gs) although this is optional and not always implemented. The GPRS Core Network The GPRS Core Network shown here consists of SGSN which is connected to the BSS by the Gb interface and the GGSN. These two devices are connected together to a private IP network called the GPRS backbone shown as the Gn Reference Point. http://www.pulsewan.com/data101/gsm_basics.htm http://sinarsuryakomindo.blogspot.com/2008/10/gsm-history.html http://foosms.com/gsm.htm MODULATION TECHNIQUE Modulation is the technique of embedment of a signal into the carrier frequency (wave). There may be analog (includes FM, AM) or digital modulation. In digital modulation Binary values 0 and 1 is embedded in the carrier frequency by changing its frequency, amplitude or phase. In this way digital modulation may be ASK (Amplitude shift keying), FSK (Frequency shift keying) or PSK (Phase shift keying). In GSM, GMSK (â€Å"Gaussian Minimum shift keying†, also known as â€Å"Gaussian filtered Minimum Shift Keying†) Modulation technique is used which is a type of FSK that continuously uses Phase modulation. Advantages of GMSK over other techniques-> * Being able to carry digital modulation and efficiently using spectrum. * Sidebands do not extend outwards from main carrier like other phase shift keying and thus, it avoids interference. * No discontinuities as change in frequency occur at â€Å"carrier zero† crossing points. * Being continuous frequency shift keying modulation scheme. It uses the frequency hopping technique, which involves switching the call frequency many times per second for security. GMSK Fundamentals The unique factor of MSK (Maximum Shift Keying) is that frequency difference between the logical 1 and 0 states always equals to half of data rate, expressed in modulation index terms and always being equal to 0.5. MSK modulation Signal using MSK modulation Sidebands extend can be easily traced in the plot drawn for the spectrum of an MSK signal. Therefore before applying it to the carrier modulating signal is passed through a low pass filter (Gaussian filter). Before filtering it must have narrow bandwidth, sharp cut-off and impulse response should have no overshoot. Finally MSK signal gets converted to GMSK modulation. Spectral density of MSK and GMSK signals Spectral density of MSK and GMSK signals Generation of MSK Modulation There are mainly two ways of to generate MSK modulation. Description of First way- The filtering of Modulating signal is done using Gaussian filter and then it is applied to frequency Modulator to set modulation index to 0.5. It is the simplest way. Its limitation lies in the fact that Modulation index must exactly equal to 0.5, which is practically not suitable as drifts are experienced by the components (which is not possible to be set exactly). Generating GMSK using a Gaussian filter and VCO Generating GMSK using Gaussian filter VCO Description of second way- Quadrature Modulator (or I-Q Modulator) is one of the ways. Here the phase of a signal lies in quadrature or 90 degrees to other one. It uses one signal, known as to be in-phase and another being quadrature to the first one. Use of Modulator of this type the Modulator index is exactly maintained to 0.5 without any further setting. Thus it is much easier to use and also it provides the required level of performance. Block diagram of I-Q modulator used to create GMSK Block diagram of I-Q modulator used to create GMSK For Demodulation the above techniques can be used in reverse. BASIC IMPLEMENTATION REQUIREMENTS HARDWARE AND SOFTWARE REQUIREMENTS- The three systems of GSM are * Switching system (SS) * Base station system (BSS) * Operation and support system (OSS) The Switching System- It is responsible for all call processing and other functions with following described units. GSM Network Elements Home Location Register (HLR)- It is the most important database of an operator storing every important details of subscribed customer. Whenever a customer buys a new connection his registration is made in HLR. Mobile services switching centre (MSC)- It performs telephony switching functions of system including controlling calls to and from other telephone and data systems. Visitor Location registers (VLR)- When a cell phone roams into a new MSC area, VLR connected to that MSC requests for data about mobile station from HLR. Later VLR will not need to interrogate HLR whenever customer makes any call. Authentication centre (AUC)- It verifies each callers identity and ensures confidentiality of each call. Equipment Identity Register (EIR)- This database stores information of Mobile devices thus preventing calla from unauthorised or stolen ones. Base Station System- It consists of Base Station Controllers (BSC)- It is the switch serving as physical links between MSC and BTS also providing functions like handover, cell configuration data, and control of Radio frequency (RF) power levels in BTS. Base Transceiver Stations (BTS)- It is the radio equipment which serves each cell in Network. A group of BTS are controlled by BSC. GSM Telecommunication Tower Operation and Support System (OMC)- This entity (connected to all equipment in switching System and to BSC) helps the operator to govern the whole system and offer customer cost-effective support and maintenance activities need for GSM network. Additional Elements- Message centre (MXE)- It Handles SMS, voice mail, fax mail, email, and cell broadcast. Mobile Service Node (MSN)- It governs Mobile intelligent network (IN) services. Gateway Mobile Services Switching Centre (GMSC)- It interconnects two networks. MSC then known as GMSC. GSM Interworking Unit (GIWU)- It consists of Hardwires and Software both and acts as an interface to various network for data communication. Problems in Implementation of Technology:- Ø Implementation of GSM technology requires a number of equipment. Many equipment need to be installed like tall towers. These towers are fixed at proper area in line of sight. Also satellites functionality also requires attention. Ø Installation of Several equipment and devices require huge amount of money. Thus GSM architecture is very costly. Ø Maintenance of equipment used in GSM is practically not affordable time and again. Ø There are several protocols applied in GSM Technology, resulting problem in implementation. Ø There is possibility of breaking into GSM networks that use cipher text-only cryptanalysis encrypted communication. These attacks are based on security flaws of the GSM protocols, and work whenever the mobile phone supports A5/2. Ø The available radio frequencies need to be re-used closer together and continuously within the network so that spectral efficiency can be unlimited. Ø There is huge consumption of power in GSM implementation, which is not convenient. Ø GSM is also not secure as the sent signal or message is not so much hard to be decoded. So the third party may avail of it somehow using some technology. ABOUT THE TECHNOLOGY GSM (Global System for Mobile communications: originally from Groupe Special Mobile) is the most widely used digital cellular technology for transmitting mobile voice and data services in the world. It uses SIM (SubscriberIdentityModule) cards, which acts as digital identity, and is tied to the cellular network by searching for cells towards the towers (bts) in the nearby location. GSM is a second-generation (2G) cell phone system used by over 3 billion people across more than 212 countries and territories. In over twenty years of development, GSM has been continuously upgraded to provide better signal, speech quality and thus fulfil the mass demands. It also facilitates to roam, switch carriers and the operators without replacement of handsets. 01-01-10 The GSM technology originally originated by the European Conference of Postal and Telecommunications Administrations (CEPT) in 1982 when it firstly created Group Special Mobile (GSM) for the purpose of designing a pan-European mobile technology. European Telecommunications Standardization Institute (ETSI) later in 1991 adopted the GSM standard. GSM technology was firstly commercially lunched in 1991 in Finland, although it has been for testing purposes since 1980. 01-01-5 Newer versions of the standard are much compatible with the original GSM system. For example,Release 97,the General Packet Radio Service (GPRS) added the packet data capabilities to GSM technology. Release 99 introduced higher speed data transmission usingEnhanced Data Rates for GSM Evolution(EDGE). It uses variation of Time Division Multiple Access (TDMA) and is the most widely used of the three digital wireless telephone technologies (TDMA, GSM, and CDMA). Data is digitized and compressed and, sent down a channel with two other streams of user data, each in its own time slot. Most 2G GSM networks operates in the 900MHz or 1800MHz bands. It operates on four different frequencies worldwide. GSM calls are either based on data or voice. Voice calls use audio codecs called half-rate, full-rate and enhanced full-rate. Data calls can turn the cell phone into a modem operating at 9600 bps having ability to carry 64 kbps to 120 Mbps of data rates. GSM technology even keeps people in touch while roaming also as it home operators are having roaming collaboration with foreign operators. IMPORTANCE OF TECHNOLOGY GSM is the most popular, reliable and the fast growing wireless technology for mobile phones in the world. It has approximately covered the 89% share market of the global mobile telecom in more than 219 countries and territories with more than 3.8 billion people as per May 2009 study. Its signalling and speech channels being digital differs it from its and so pronounced as a second generation (2G) mobile phone system. This has also meant that data communication was easy to build into the system. It also provides the integrated high-speed data, fax, paging, voice mail and short messages services (SMS) capabilities and thus offering communication to be secure, private and fraud prevented. Many operators provide access to ISDN services to transmit data fast. Several offer GPRS facility to connect to high speed data communication channel (9600 bps). Global GSM Growth GSM market share has grown at exponent rate over recent years. However the target to achieve 1 billion customers took 12 years (Feb 2004) but later it was a surprising fact that it crossed the 2 billion mark only in another 2.5 years (By June 2006) and 3 billion GSM customers in another less than 2 years. Now the Telecoms and Media hope to surpass 5 billion targets by 2013. GSM is the legacy network of the evolution to the third generation (3G) technologies Universal Mobile Telecommunication System, (UMTS) also known as WCDMA, and High Speed Packet Access (HSPA). Maximum Mobile phones manufacturer develop their products based on GSM technology and all mobile companies provide their customers GSM networks. The Social Impact of Mobile Telephony Mobile telephony is undoubted one of the most superb developments telecommunications industry. The number of subscribers is rapidly increasing in tremendous way. More and more people are being connected to the telecom. GSM technology has greatly affected the social life. The various operators have been proving a number of offers to fascinate their customers. Due to aspects like reliability, security, voice and data transmission facilities GSM is much popular among the users. People are shifting to wireless communication from their fixed phones. Rapid increase in GSM market Popularity Reasons of GSM Technology * Improved spectrum efficiency. * High speech quality. * International roaming. * Better signal quality. * Offer voice, data and fax. * Offer secure communication and privacy. * Low-cost mobile sets and base stations (BSs). * Flexibility SIM. * High share market capture. * Low terminal and service cost. * ISDN compatibility. * Compatibility with Integrated Services Digital Network (ISDN) for data transmission. * Support for new services like VAS. Backbone for 3G and other evaluating technologies GSM customer growth in India Health Issues It is the recent report that use of GSM mobile technology poses Health Hazards. Its regular and continuous use for hours may create heath problems like irritations, allergies, headache, ears pain etc. It is fact proved by scientists that radio waves of frequencies that it utilises can create electric fieldsin human cells and brain. Long term exposure may have adverse health effects too. Many research institutions controlled by government and independent bodies are continuously studying over it. Also research results are being revived by ICNIRP (International Commission on Non-Ionizing Radiation Protection) and the WHO (World Health Organisation) at global level. Use of cellular phone is highly restricted to be turned off while in flight as the radio frequencies may interfere. The same case happens at hospitals as the radio signal may create interference with electronic medical devices at short rang or cause uneasiness among patients. While driving use of cell phone is advised to avoid and in petrol pumps as the radio waves used in GSM technology may cause interference. d> GSM SECURITY:- 1. PURPOSE OF USING GSM SECURITY:- As we know that security is the essential feature in any service. Hence, GSM network also follows certain level of security in the services which it provides. Hence, there are mainly two security purposes which are kept in mind when it is concerned of the GSM network:- First of all, to protect the Accessibility to the mobile services and secondly to prevent disclosure of any crucial information/data at the radio path to achieve the privacy regarding that particular data. 2. THE SECURITY FEATURES OF THE GSM SERVICES:- There are several features of the GSM service for the security of its customers. Some features are stated below: 1. Authentication is being provided to the registered customers only. 2. The process of encryption is being used for secure data transfer. 3. The identity of customer is being verified. 4. The cellular phones are useless without a SIM card. 5. A secret key Ki is being used to achieve authentication. 3. Representation of the GSM Security:- GSM security is represented in two ways:- a. Authentication b. Encryption A. Authentication: The process of authentication is being categorized in to various stages which are stated below:- 1. First of all an IMSI (International mobile subscriber Identity) is being send to the network by the mobile station. 2. After that the IMSI is being received by the network and the KI corresponding to that IMSI is found. 3. A 128 bit random number (RAND) gets generated by the corresponding network and is send to the mobile station through the medium of air. 4. Through the use of the algorithm A3, the network (AuC) and the MS (SIM) use KI and RAND to produce a signed result (SRES). 5. The SRES is being sent to the network by the MS. 6. For the validity purpose network performs the testing on the received SRES. B. Encryption: The process of encryption gets started by ciphering mode request (i.e.: secretly executed request) command from the GSM network. After receiving the request the process of encryption and decryption of data gets performed by the mobile station. Different key stream is involved in the encryption of each frame over the air traffic. Different key stream is generated for each frame as the A5algorithm which is used to encrypt the data is initialised with the KC and the number of the frame to be executed resulting in the generation of different key stream. The same KC gets executed as long as it does not get verified by the MSC (Mobile services switching Centre) through the MS(mobile station) which results in the generation of the new KC. The Authentication of MS is an optional process and is usually not performed in the beginning of a call. Hence it is assured that the KC will not get changed during a particular call. As it gets switched off IMSI (International mobile subscriber identity) gets stored by the mobile station on the SIM card to assure that is gets available when it is switched on again. In the hardware of the mobile phone the A5 algorithm gets executed as data is being encrypted and decrypted through the air. 4. The Algorithm used in the GSM Security: There are three algorithms which are used in the GSM security:- 1> A3: The MS Authentication Algorithm:- In the GSM model, A3 acts as the authentication algorithm. This algorithm generates a 32 bit output as it gets the RAND (128 bit random number) from the MSC (Mobile service switching Centre) and the secret key KI as input from the SIM. The size of KI and RAND is of 128 bits. The A3 algorithm is represented as a one-way hash function. This function produces an output which is of fixed length as a random input is given to it. A COMP 128 algorithm is used for the A3 algorithm by every GSM operator in the world. This algorithm acts as the reference algorithm for the various tasks which has been pointed out by the GSM association. 2> A8, The ciphering Key Generation Algorithm: In the GSM network, A8 algorithm acts the session key algorithm. The A8 algorithm generates 64 bit output by taking two 128 bit input. The output generated is 64 bit session key KC. COMP128 acts the reference algorithm for the A8 algorithm also as it is there in the A3 algorithm. At one run, COMP128 generates both the session key KC as well as the SRES response. 3> A5, the stream-ciphering algorithm: In this algorithm encryption of data over the air occurs. For secure data, there are three possibilities in the case of GSM; it includes the A5/0, A5/1 and the A5/2 algorithm. This algorithm came into existence because the GSM standard was designed for Europe and as per the export regulations it did not allow the implementation of the technology outside Europe. f> Advantage of GSM Services:- Following are the Advantage of GSM service: - 1>First of all the GSM network is fully developed which means that it contains stability with proper features and services. Hence it has over 450 million subscribers worldwide. 2> The other advantage of GSM network is that it contains better voice quality and low- cost alternatives to make calls, such as Short message service (SMS) . In the case of GSM network the quality of voice is fine inside the buildings. 3) Another advantage of this service is that the equipments are easily available from the vendors who execute the following service. 4> GSM services provide the roaming facility to its customers so that they can use the service anywhere in the world. 5) GSM networks provide higher talk time due to its pulse nature of transmission and its ability to use routers. 6) GSM provides the facility of International Roaming which is highly beneficial in context to its customers. 7> The presence of Smart Cards which acts as subscriber Identity Modules through which encryption of data occurs in a secure manner which is highly advantageous with respect to commercial background. 8> lastly the common advantage of the GSM service is that it provides the user the freedom to choose a mobile set of his/her choice and the SIM card is also being selected by user of their choice.
