Emerging Technologies and Innovation (Information Technology)

Question: Talk about the Emerging Technologies and Innovation (Information Technology). Answer: Presentation: The connection of the people over the informal communication destinations is on nonstop increment. The individuals are pretty much consistently associated with the assistance of the long range interpersonal communication locales. These long range interpersonal communication locales are utilized by the people for different purposes, either for the business reason or to speak with others over the individual issues. The clients today are getting a charge out of the offices of staying in contact with one another anytime of time and regardless of whether they dwell at wherever. For the individuals in the previous days it had been a marvel to keep in contact with one another when they are dwelling in various nations or domains. The developments and the new creations made by the rising science and innovation prompted the rise of the product and the related locales that began making the associations among the people for different purposes significantly more smooth and simple that should be p ossible inside a couple of moments (Feng et al. 2014). The long range informal communication locales, for example, Twitter, Facebook , Flickr, MySpace, and other informing destinations, for example, the portable envoys that can be utilized through the versatile systems are increasing increasingly more fame among the Internet clients (Cheminod et al. 2013). The Internet clients are a lot of occupied with using the benefits of such systems administration media. The sharing of the information has now gone to be an expansive application and one of the fundamental pieces of regular day to day existence. Individuals these days or rather in todays computerized world can't consider driving their lives without the nearness of such person to person communication locales, at each position, or rather at each second they are needing staying associated or on line by means of the vehicle of such information. The prominence and expanding utilization of the information sharing permit the constant correspondence among the clients, they permit texting just as web calling among the clients despite the fact that they live at various areas. The clients of the OSN or the online long range interpersonal communication locales, for example, Facebook, Twitter, Instagram, MySpace can share the necessary data or information without any problem. These long range informal communication locales give the spaces to the individuals through which they can without much of a stretch convey interface with the individuals who are obscure to them and can grow new contacts. Be that as it may, this demonstration of getting a charge out of the unknown correspondence or sharing the information secretly can prompt different hindrances. There consistently stays a danger of the information getting hacked by the web programmers or when such information will be abused for the antagonistic activities, concerning example when the people make an entrance to the private system with no legitimate consent and offer the information in an unlawful way by the methods for p rofiling the proprietor of the information whose private data is penetrated by such unfavorable action(Galliers Leidner, 2014). The computerized present reality has offered ascend to numerous favorable circumstances and the individuals can get numerous important information in regards to a plenty of perspectives, individuals these days scarcely need to ponder or think hard for looking through any significance or any data. The nearness of Internet and all the sorts of useful programming applications have made it very conceivable. Be that as it may, the utilization of the online long range interpersonal communication destinations to speak with the assistance of the couriers in Facebook, talks, home bases, MySpace, Twitter and numerous different applications or systems administration locales, have brought to the cutting edge numerous protection issues as these systems administration locales consistently stay powerless to various dangers, for example, the spillage of data, defilement of information and furthermore the break of security (Li et al.2012). The data, consequently, which is shared by the people connected actually and the information shared by the corporate areas for the should be remained careful and made sure about from being unlawfully abused. The corporate business areas have an incredible need of protecting their data identified with the business interests. In this manner, the associations spare their basic data with the assistance of the International Standard known as the Information Security Management framework (ISMS), in this manner saving the imperative information from security reveals. An ISMS is the security framework that utilizes the ISO principles so as to ensure the protection and secrecy of the basic data (Hill et al. 2014). Criticalness of the examination: The significant reason or the significance of this top to bottom investigation is to procure the necessary data from the examinations made before in regards to the comparable subject and to coordinate the comparable data obtained with that of the assessments that he himself have and along these lines, all the while, cause the perusers to comprehend and get information about different parts of the online long range interpersonal communication destinations and the issues identified with the upkeep of protection of the correspondence that is led with the assistance of the methods for such person to person communication locales. The report has endeavored to embrace a top to bottom investigation of the Industrial Control Systems (ICS) that is utilized for ensuring the wellbeing of the data identified with the open frameworks that is extremely indispensable for the nation. The analyst in this way gives data pretty much all the safety efforts and guidelines that can be embraced and are norm ally received by the organizations both the private and open segments so as to make sure about the protection of the data and most significant information (Hahn et al. 2013). Explicit points of the Report: ISMS can undoubtedly ensure the data and hold the protection of specific issues; anyway it isn't taken to be a lot of appropriate to handle the basic data. Despite the fact that ISO 27001 imprints the framework of the ISMS, and it can spare the security of the general data frameworks and can be actualized effectively, it can't give the wellbeing that is required by the foundation proprietors of IC, who along these lines really adhere to the security gauges of IEC 61508 and IEC 61511. Subsequently, accordingly, for the support of the secrecy, accessibility, security and protection of the whole data frameworks or the ICS another Information Security Management System is required to be created (Lees 2012). Along these lines, the reason for this report is to distinguish another model SNSM for mysterious correspondence conspires in informal community Security model in the wake of examining the gauges, for example, the ISO, NIST SP 800-53s and the IEC 61511 norms. Subsequently, the analyst in this interest will manage the accompanying points that would help in directing the investigation or the examination: To distinguish the significance qualities of the unknown correspondence plots in the informal community To discover the procedures by which the security and protection are working in the mysterious correspondence plots in the interpersonal organization To contemplate and distinguish the security control or prerequisites of three global gauges, in particular, IEC 61511, NIST SP 800-53s and ISO Hence, the scientist would attempt to manage the above points and lead the examination so as to know the probabilities of structuring another arrangement of Information or another model that can help in the conservation of the information sharing (Wirth et al. 2016). Issues (Problem Statement): In this very area the analyst will give the perusers an inside and out investigation about the element of the correspondence frameworks, the methods of information sharing and a few different perspectives in regards to the significance of security in the correspondence frameworks. Through the assortment of data about various angles identified with the theme from the auxiliary information sources the report would make the perusers mindful of every viewpoint through a significant and careful investigation of the issues (Chretien Kind, 2013). The issues that generally emerge are with respect to the introduction of the personalities of the clients who dislike to get their genuine characters uncovered, notwithstanding, as a matter of course a portion of the interpersonal interaction destinations or sites may require the clients to uncover their actual personalities for making their profiles in those online long range interpersonal communication locales. Such security issues influence to a great extent the points of view of different clients to utilize those destinations for leading certain significant correspondence or work. Along these lines, two significant issues can be distinguished dependent on this current situation of security concerns. These two issues involve the personality of the clients and the secrecy of the clients. The clients in the wake of uncovering their actual or genuine personalities in the interpersonal interaction sites get an introduction and their profiles or the records shaped in such locales becom e known by different clients as well. Presently, regularly it might happen that the programmers or the assailants of the security of the profiles with assistance of web search tools attempt to record the records of specific clients on the off chance that they are the clients of a typical person to person communication website. This thusly empowers the programmer of the records to discover the data about the people in question or the clients with the assistance of the indexed lists, and along these lines uncover the obscurity of the clients of such long range informal communication sites or applications. There are different ways too which can be utilized by the assailants, in particular the Neighborhood Attack and De-Anonymization assault, to get to the security of the profiles of specific clients (Rock et al. 2013). Writing Review: This area would manage an inside and out investigation identified with the International measures that are embraced by the business associations so as to ensure the break of the private and essential correspondence. Through this area the perusers will get mindful about the significance of such universal principles that are actualized by the organizations just as the hugeness of shielding the security of such data that happens among different associations and among the people with respect to the individual issues. With the assistance of the optional information sources this report will attempt to reply and manage the recognizable proof of the highlights

Avoiding Groupthink Avoiding Fatal Flaws in Group Decision Making

Avoiding Groupthink Avoiding Fatal Flaws in Group Decision Making You will agree that making decisions is not the easiest thing to do. Still, we do it, every day, every minute, every second.Sometimes we are quite aware of that process, while in other moments we are not.And there are times when we simply cannot make out whether we are using our own heads during the procedure, or perhaps it’s a result of a group impact.Our task here is to help you learn more about avoiding groupthink.Find out more about avoiding fatal flaws in group decision making as that’s the only way to keep things going the right way-your way.Each type of thinking has its own pros and cons, but some people find it difficult to stick to their own opinions and beliefs.That’s because they lack some basic skills which may help them strengthen their own attitude and be more self-confident.Stay with us for more useful tips!HOW TO DEFINE GROUPTHINK?You probably know the moment- the one when you feel that things are on some desirable course and out of nowhere “blindspots” appe ar and confuse you!You realize that you don’t even know what were you suppose to decide about, is it your duty after all or should the group be involved as well?Congrats, you are a just about to get into the nasty trap called Groupthink! This intriguing term was created back in 1972 by Irving L. Janis.This social psychologist used it to describe an interesting phenomenon in which individuals often set aside their own beliefs and opt for the one that the group shares, striving to make a consensus.It’s an integral part of human’s nature to use common sense while making a decision.This involves several components such as expressing critiques and unpopular attitudes, giving alternatives.However, when the phenomenon we mentioned takes its place, the ability to make decisions and solve issues using exclusively your head slowly begins to fade away.Of course, this does not mean that sharing the same opinion with the group is necessarily a bad thing always.The psychologist wanted to fi nd out that curious case where the group can make a good decision in one moment and then make a disastrous one in the very next.Long story short- he blamed it all on poor analyses of alternatives as well as the lack of opposing opinions and conflicts.On top of it all, he also pointed out that an insufficient amount of information leads to the impossibility to make an informed decision.Before we get deeper into analyzing this phenomenon, allow us to give you two most popular examples that illustrate it. Those are Challenger Space Shuttle disaster and Bay of Pigs invasion.In the first one, engineers of the spacecraft were knowledgeable about some faulty parts months before the launch, but they did not want negative press so they proceeded with the take-off anyway.The other one refers to President Kennedy’s decision which encountered the support from individuals around him, despite their concerns.RECOGNIZING GROUPTHINK-LEARNING THE SYMPTOMSNow that you have the definition, you may th ink that spotting it is as simple as it can be.Well, don’t be fooled, because even though the explanation itself is rather clear, numerous factors which are included in it make it more challenging to recognize it easily.However, there are several occasions where this phenomenon occurs more frequently, and that’s when there’s:Extreme cohesion in the teamPlenty of strong external pressure to make a good decisionAn atmosphere of isolation where a team operatesA determined and persuasive leader to represent the groupNo standard means for evaluation of suggestionsHomogenous ideology and social background of the teamPlenty of performance-related stress in the communityA recent failure and numerous moral dilemmasUnveiling a layer by layer of this complex behavior leads us to the next step, which is learning more about the symptoms which are common for it. Here comes the list: Peer PressureWhen an individual in the team gives an opinion which opposes to the one others have or question s the rationality behind a decision, the rest of the group work unitedly to pressure or penalize that person and make him/her compliant.Such individuals are often considered to be a sort of traitorous and disloyal outcasts.It’s a common case that the group puts a sarcastic demand before such person, by reminding him/her that leaving the team is an option if such person feels that the group is making a mistake. StereotypingThis usually comes as a result of uninformed views in the group.Those who advocate individual opinion are seen as party breakers because having an opposite and inferior set of morals and characteristics from the rest of the team is simply not right.Such a group attitude leads to discrediting someone’s opposition.This goes so far that the group even begins to ignore or demonize the “outcasts” who may oppose, question or challenge the teams ideas. ComplacencyThis is one of the most common traps which often appears as a consequence of the first two symptoms we described.After a few rightfully made decisions, the community begins to feel like anything they decide is the unquestionably correct one because no-one disagrees with it.To strengthen such common belief and keep the community under such an impression, the track record of successful (group) decisions is often mentioned.The purpose of this is to encourage people to believe that group thinking is the only way to reach success. CensorshipTo make individuals censor their opinions, by persuading themselves that their thoughts are surely wrong if they are different from the rest of the group.Any information that is not compatible with what the team advocates is strongly rejected. There are no alternatives. RationalizationThis occurs when the entire team convinces themselves that the group decision is the best one, despite evidence that proves otherwise.As an argument, such people often say that the others haven’t researched the situation to the detail, which is why their (individual) d ecision is not right. Moral High Ground In a group, each person believes that he/she is ethical.When a group consists of several moral minds, it’s impossible to make a poor decision.Adding righteousness as a mandatory component for making decisions, the pressure gradually grows.That’s because no-one wants to be seen as immoral. Illusion of ConsensusWhen no-one’s opinion stands out or no individual speaks out, the entire team feels the communitys decision is unanimous.Such an attitude feeds the Groupthink and everyone believes that the entire community feels the same. IS IT POSSIBLE TO AVOID GROUPTHINK?if you feel that during a meeting the mentioned symptoms are present, stay calm. Panic won’t help, but a clear mind will.What has to be done is think of smart ways to prevent killing critical thinking and inspire individuals to have an uncommon approach while solving problems.Here’s a procedure that might be of help:1) Everyone in the team should have a critical evaluation of ideas.This is one of the simplest steps.How to perform it, you wonder?Well, ask everyone in the team to take several moments to note down both the advantages and disadvantages of suggestions that have been given before the debate takes place.Though this is more than simple, not everybody feels free enough to express themselves. If you are still worried, there’s a solution to solve all your worries.Get a polling app that allows individuals in the team to vote or comment on subjects anonymously.2) The boss of the team must keep all ideas to him/herself.When one is a leader, his/her opinions have a big impact on others.That’s where the issues may appear, as shy employees will think twice before disagreeing with the leader’s opinion or suggesting an idea that is better than the one expressed by the leader.Leaders should try to prevent the situation where his/her beliefs lead to a discussion.If that happened, plenty of great opportunities to discover individual talents and strengt hs in the team will be missed, and that is sometimes critical to future successes.3) The team head should be a no-show.Even when one is completely silent, body language is never on mute. It’s impossible to turn it off.That’s particularly problematic during meetings.Even when one says nothing, people in the team know his/her feeling about the situation.If you want to boost the self-confidence in individuals in your team, let them know that you value their suggestions so much that you plan to be absent from certain group discussions.That way your presence won’t have a notable impact on the final result.4) Consider a team approach.In case the community is a larger one, try with randomly dividing members into smaller communities. Give them the task to work on the same issue.Such an approach will have multiple benefits for the group- it will strengthen the relationship between people in the team, they will learn to discuss and value each other’s opinions.What’s even more, such a competitive atmosphere will inspire them to propose as many solutions as possible, striving to give the best one that will win.5) A thorough investigation of all alternatives.After the team came up with a list of suggestions or solutions, submit them to a standardized method of assessment.This is a simple procedure, as all it takes is to give the answers to some common questions such as:How does this concept support the goal?What are the expenses of this approach?What are the risks behind such a decision? and similar.6) An external perspective is a must.When the evaluation of various ideas and solutions begins, here’s an extra assignment for each member of the team. Ask them to get an outsider’s opinion.This works for the majority of the situation.However, if the solutions being discussed are sensitive, advise members to talk to specific and trusted leader inside the organization.7) Consultations from an outbound expert.Even when the team is highly specialized in a specific ni che, sometimes a project or solution has segments that go beyond the expertise of the community.The best move in such situations is to consider asking an outside expert to attend the meeting and participate in the discussion solutions proposed by the team.Outsiders often give a refreshing change to community dynamics, and expert opinions make it possible for everyone in the group to learn from a professionals understandings and wisdom.8) Who gets to be the devil’s advocate today?Once all the participants are present, draw straws to see who will be in charge of playing the devil’s advocate for the discussion.The chosen person will have to “think like an enemy” and oppose all popular suggestions during the discussion.The purpose of this is to support healthy debate and test the strength of different arguments.USEFUL TECHNIQUES TO DEAL WITH GROUPTHINKWhat made a revolution in approaching the problems in a company or a group is- team building activities.By playing a variety of e ngaging games, solving seemingly silly tasks and having lots of fun, members of the group build a strong relationship with each other.Here are two “games” we selected, which can minimize risk for Groupthink to show up:Six Thinking HatsThis interesting challenge forces you to leave aside your customary thinking style and to approach things from several various perspectives.This allows you to get a more complete overlook of your situation.Each of the hats represents a diverse way of thinking, and here’s what each of them means:White portrays your concentrate on the available information.You have to look at the data you have, analyze past tendencies, and find out what you can learn from it.The task is to find gaps in your knowledge and do your best to fill them or use them as a direction what is it that you should learn.Red represents intuition, gut reaction, and feelings when you are trying to solve the issue.While “wearing” this one, take other people’s emotional reaction s into consideration.Do your best to understand the responses of individuals who are not fully familiar with your reasoning.Black illustrates potentially negative consequences in the thinking process.Therefore, your attitude has to be cautious and defensive to see why it might not work.To put things simply, this hat highlights the weak points in the strategy and while “wearing” it, you have the power to eliminate and change them, or come up with several emergency plans to fight them.This way of reasoning toughens you and your plan-making process. Thanks to this, you can spot potentially fatal mistakes and risks before you take any action.The ultimate advantage of this hat is the “super-vision” that a person gets.Sometimes successful individual gets so used to a positive way of thinking that they often miss seeing issues in advance, which is why they become under-prepared for difficult moments.The yellow hat is the one to boost positive reasoning.Such an optimistic view serve s so you can see all the good sides of the decision as well as the value in it.When everything looks miserable and difficult, put on this one, and the perspective will suddenly become brighter.Green equals creativity. When this one’s on your head, you suggest uncommon and ingenious answers to a problem. It is a free way of thinking, in which there is little criticism of concepts.Blue indicates process control. Individuals who chair the meetings usually wear this one. When difficult moments occur because suggestions are running dry, they may lead activity into the creative direction by putting the green one on.When emergency plans are necessary, they will look for the Black one to wear.BrainstormingOn the contrary, there’s nothing stormy here, as this procedure mixes a relaxed, informal approach to fixing issues with lateral thinking.The purpose of such a method is to motivate individuals to come up with suggestions that can, at first, seem a bit silly.Some of these concepts can be transformed into original, uncommon answers to the situation, while others can trigger even more concepts.This helps to get individuals unstuck by inspiring them to abandon their common ways of doing things and making them think outside the box.During these sessions, individuals should avoid criticizing or rewarding suggestions.The goal is to come up with numerous options and break down wrong premises about the problems limits.Judgment and analysis at this phase obstruct concept creation and limit originality. Evaluation of suggested concepts takes place at the end of the session.That’s where using common methods occur.Standard group problem solving can often be jeopardized by unhelpful community behavior.And while its significant, to begin with, a structured, analytical procedure when fixing issues, this can lead a community to develop a restricted and unimaginative approach to suggesting concepts.By contrast, this approach provides a free and open surrounding that motivates e veryone to be involved.Unconventional suggestions are welcomed and supported, and all members are inspired to contribute fully, helping them deliver a wide range of creative concepts.When used during fixing issues, this process brings community members diverse experience into play. It levels-up the richness of suggestions explored, which means that you can often find better answers to the issues that you are confronted with.It can also help you get buy-in from community members for the selected solution â€" after all, theyre likely to be more dedicated to an approach if they were involved in developing it.Whats more, because masterminding is fun, it helps group members strengthen their relationships with each other, as they fix issues in a positive, rewarding atmosphere.While this process can be effective, its significant to deal with it with an open-minded and non-judgmental way of thinking. If you dont do this, people don’t feel like suggesting anything, the number, and quality of ideas decrease, and morale can suffer. OVERCOMING GROUPTHINKHowever, if the phenomenon does set in, you must recognize and announce its presence rapidly so that you can overcome it and get back to functioning effectively.These are the steps to go beyond it with as less trouble as possible:Even with good group decision-making processes in place, watch out for signals, so you can deal with them as soon as you spot them.If there are signs of the phenomenon, talk about them in the community. Once confirmed, the team as a whole can consciously free up its decision making.Evaluate the immediate risks of any approach, and the consequences for the community and its members. If they are high (for example risk of personal safety), make sure you take steps to completely analyze any decision before it is approved.If appropriate, seek outside approval, get more external data, and test hypothesis. Refer to these steps above as a starting point in spotting things that need to be altered.Come up with ordinary group techniques and decision-making tools and encourage the community to think of their “games”.CONCLUSIONAs you have seen, this phenomenon is not a rare one, but still, there are ways to learn to spot it and deal with it.We gave you the definition along with the list of symptoms so that you can be aware of it when this process occurs.Besides this, you are now familiar with practical techniques and games that will help you overcome it and support a creative and positive way of thinking.Each person and his/her opinion has its unique value and can give a valuable contribution, particularly when the problem is complex and multi-layered.Thats why open-mindedness and critical thinking should always be encouraged.With such energy in the team, the chances to be successful are even bigger.And thats exactly what motivates individuals to keep on pushing, for their own and the benefit of the community.Use our guide as a reference whenever you have doubts and always look for more games and techniques to improve skills and learn to eventually eliminate even the slightest possibility for Groupthink to occur.

Down With the Five Paragraph Essay!

Writing essays is a skill that will serve kids well throughout their lives. Knowing how to present facts and opinions in an interesting, understandable way is valuable regardless of whether they attend college or go directly into the workforce.   Unfortunately, the current trend  is to focus on a type of writing called the Five Paragraph Essay. This fill-in-the-blank style of writing has one main goal - training students to write essays that are easy to grade in the classroom and on standardized tests. As a homeschooling parent, you can help your children learn to produce informational writing that is meaningful and alive.   The Problem with the Five Paragraph Essay In the real world, people write essays to inform, persuade, and entertain. The Five Paragraph Essay allows writers to  do that but only in a limited way. The structure of the Five Paragraph Essay consists of: An introductory paragraph that states the point to be made.Three paragraphs of exposition that each lay out one point of the argument.A conclusion that sums up the essays content. For beginning writers, this formula can be a good starting place. The Five Paragraph Essay can help young students get beyond the one-paragraph page, and encourage them to come up with multiple facts or arguments. But beyond fifth grade or so, the Five Paragraph Essay becomes an obstacle to quality writing. Instead of learning to develop and vary their arguments, students remain stuck in the same old formula. According to Chicago Public School English teacher Ray Salazar, The five-paragraph essay is rudimentary, unengaging, and useless. SAT Prep Trains Students to Write Poorly The SAT essay format is even worse. It values speed over accuracy and depth of thought. Students are conditioned to turn out a large number of words quickly, rather than to take the time to present their arguments well. Ironically, the Five Paragraph Essay works against the SAT essay format. In 2005, Les Perelman of MIT found that he could predict the score on an SAT essay solely on the basis of how many paragraphs it contained. So to get a top score of six, a test taker would have to write six paragraphs, not five. Teaching Informational Writing Dont feel you need to assign your children school-type writing projects. Real-life writing is often more valuable and more meaningful to them. Suggestions include: Keep a journal. Many kids enjoy keeping a journal or notebook to capture their thoughts. It can be something to share with you (some teachers use journals to communicate with their students; you can do the same) or a private record. Either way provides useful writing practice.Start a blog. Even reluctant writers can become enthusiastic when writing has a purpose. Writing for an audience provides purpose. There are many options for starting a free blog and privacy features offer parents and students control over who reads the content.Write a review. Ask your kids to review their favorite books, video games, movies, restaurants -  the list is endless. Unlike most school-type reports, reviews have to be written with the audience in mind, and they have to be entertaining. They also help kids learn to express opinions and present valid arguments to the reader.Do a research paper. Give your kids essay-writing a purpose by integrating it into a history project or science topic. Let them c hoose an area that interests them and explore it in depth. Writing research papers also gives students practice in critical thinking and evaluating and crediting source material. Essay Writing Resources If you need some guidance, there are some fantastic online resources for writing essays.   How to Write an Essay: 10 Easy Steps.

The growth rate of circulation in digital version is 6 times in 3 years. There was a slight drop from 100,860 to 88,776 for print version from 2010 to 2013. This implies the fast growing popularity of phone affect the habit of readers and there is growing rend in digital version in the future. Michael Porter’s 5 forces 1. Bargaining Power of Paper Suppliers – Due to the cost of paper material increases, the paper suppliers will transfer the incremental cost to SCAMP. It is under great pressure to increase the price of the newspaper print. 2. Bargaining Power of Customers – Customers have little switching cost to read other newspapers. Besides, free digital version is offered by HECK Standard. 3. Threat of New Entrants – There are many English newspapers emerging in HECK market like China Daily and Wall Street Institute which provide free newspapers at some selected estates. . Threat of Substitute Products – Due to growing popularity of phone, the customers have been changing their habits of reading newspapers. Digital version or mobile APS to access the updated newspapers create tremendous treat to the traditional newspaper industry. 5. Competitive Rivalry Within An Industry – The major competitors, HECK Standard is aggressively offering 200,000 free tabloid newspapers distributed in different districts on a daily basis as well as providing free digital version to their readers. Competitor Analysis The Standard is doing the same as SCAMP to provide English newspaper print, digital erosion and Job searching function.

It also offers corporate digital subscription which allows multi-reader access to the digital version. The subscriptions allow readers to access their online and tablet content unlimitedly. We have made a comparison table between SCAMP and The Standard so that we can have more understanding of the keen competition in the newspaper industry.

Also, it encloses Classified Post for Job seekers; Young Post and Education Post for student subscribers. Market leader There are not much English newspapers being published in Hong Kong. The major competitor is The Standard. The competition is not keen. Thus, SCAMP is the market leader among English newspapers. Sustained demand SCAMP targets high-educated customers. Usually, they earn more, they can afford more. Also, those NC corporations, universities and foreign residents all have regular subscriptions. There is sustainable demand. Weakness Increased staff production cost Source: SCAMP Group 2013 Interim report – Extract of Income statement Staff and production costs have increased for about HECK$48. Million and HECK$3. Lion respectively. It is mainly due to the increase in headcount and SCAMP Group has included the production of ELL on 2013. It decreases the net profit. Less popular in HECK It costs HECK$9, which is the most expensive newspaper in Hong Kong. Also, it’s bulky in size. It’s inconvenient for readers to carry it around. Moreover, it cannot satisfy those non-Engl ish readers. It cannot become a popular newspaper in Hong Kong. Subscription for unlimited digital access If readers want to have unlimited access on digital access, they are obliged to subscribe by money. However, other Hong Kong newspapers, including The Standard, are free of charge on digital version. It may hinder the increase of digital readers as they may prefer choosing free information.

Business Accounting Land and Building

Question: Describe about the Business Accounting for Land and Building. Answer: Introduction: In the case given, there are mainly 2 proposal on which the board of the directors of the company are confused as to which alternative must be chosen. This report relates with the issue of shares and the other with the sale and leaseback of the land and building. The company undertaken for the purposes of this report is Black Box Ltd. This report and the main aim of the Black Box Ltd is to know as to which option under the given 2 proposals would be favourable for it. The company is trying to look and go for an option that results in the minimum amount of the cash outflow and also the same complies with the Australian Accounting standards. Issue of shares: The AASB 132 deals with the presentation of the various financial instruments. In respect of the equity instruments, the examples of which includes the non-puttable ordinary shares, many types of the preference shares and warrants. The issuer of these non-puttable ordinary shares takes into account the fact that there are many of the formal acts that make the distribution and also become somewhat legally obliged to the shareholders in doing the same. This would be so when there is a declaration of the dividend or when the entity is being wound up or in the case, there are any assets left out after the satisfaction of the various liabilities that becomes distributable to the shareholders. There is a purchased call option or there are some of the similar contracts that have been acquired by the entity and that gives them the right to acquire the fixed number of the equity instruments in exchange of the delivering of the fixed amounts of cash or any other financial asset which is not a financial asset for the company. Further, in respect of the settlement of the equity instrument of the company which are its own, the examples of which includes the classification of the different types of the contracts of the own equity instruments of the company. These would further include the contract that would be settled by the entity when it comes to receiving or delivering the fixed number of the own shares for the future consideration or exchanging the fixed number of the own shares of the company for the fixed amount of cash or any other financial asset which is an equity instruments. As per the standard, any amount of consideration which would be received or be paid for such of the contract would be added or be deducted from the equity. On example of the same would be the issued share option that gives the right to the company to buy some fixed number of the shares of the entity for a fixed amount of cash. In case, there is a contract that requires the entity to purchase its own shares or any other financial assets at some fixed or at a determinable date or in demand, then the entity would recognise that financial liability for the present value of that redemption amount. An example of the same would be the obligation of the entity under the forward contract to repurchase the number of its own shares for a fixed amount of cash. When an entity decides to purchase back its own shares, then that would give rise to the financial liability for the present value of the amount of redemption even in the case wherein the shares have bene obliged to be repurchased and the same is not fixed or in case, the obligation is somewhat conditional on the counterparty that exercises the right of redemption. Another example of the same is the conditional obligation which is an issued option which requires the entity to purchase the own shares of the company for cash in case the counterparty exercises this option (AASB, 2016). There could be a contract wherein the settlement may be in cash or in any other form of a financial asset. This would include the payment of cash or the financial asset that would be delivered or received on the basis of the changes made in the market price of the equity of the company. There could be a contract that could be settled in a variety of ways in the own shares of the company whose value is equal to the underlying value of that asset. Such a contract is considered to be a financial asset or a financial liability (AASB, 2016). Now, if the company goes for the payment of just $50 per shares, then there would be a cash outlay of $6,140,000 but if the company goes for the second option, then then cash outlay of the company would be $7,613,600. So, it is recommended that the company goes for the first option wherein it just has to pay $50 per share at the end of the 10 years. This is as per AASB 132. Sale and leaseback: The companys usually want to keep leases off their books since they like to defer their expenses and they do the same by the way of reporting their leases as operating leases. The financial Accounting standards Board has the following rule when it comes to treating the lease as the capital lease. The capital lease is when it meets any of the following 4 conditions: If the life of the lease is more than the 75% of the life of the asset. If there is a provision of ownership to the lessee at the end of the term of the lease. If there is an option to purchase the asset at the bargain price as in the end of the term of the lease. If the present value of the lease payments when discounted at the appropriate discount rate is more than 90% of the fair value of the asset (Stern, 2016). Under the given case, company Black Box has an option to purchase back the asset in the end of the 10 years which is the useful life of the asset. Since this condition has been fulfilled, it can be considered as a capital lease. AASB 117 on leases states that this transaction includes the sale of the asset and then leasing the same back to the seller of that asset. The payment of the lease and the sales price is interdependent since these have been negotiated as a package (Chartered Accountants, 2016). In case, the leaseback is a finance lease, then the transaction would provide the finance to the lease with the asset in the security. It is for this reason that the excess amount is never treated as the income in the statement of profit or loss. In case, the sale price of the asset is below its market value, then the any profit or loss that have been recognised shall be deferred and shall be amortised over the term of the lease for which the asset is expected to be used. In case, the leaseback is an operating lease, then the payments of the lease and if the sales price is at the fair value, and there has been a normal sales transaction, then any amount of profit or loss would be recognised immediately. For th e purposes of the finance lease, there is no adjustment necessary till there is a fall in the value in the asset in which the carrying amount would go on to reduce the amount of the recoverable as per the requirements of the AASB. The disclosure requirements for the lessees and the lessors would be applied. And the same would apply in the case of the sales and leaseback transactions as well. The required description of the material leasing arrangements would lead to the disclosing of the unique or an unusual provision of the terms and the agreement of the transactions of sales and leaseback (AASB, 2016). If we follow the above stated standard on accounting, then it is a capital lease but the company would benefit if it goes for the operating lease. The company if it goes for the operating lease would pay and the amount of the lease and would charge the stated expense as against the profit for each year but if it goes for the capital lease, then it would be entitled for the depreciation and also, the lease payment would be treated like a loan. So, double benefit in the case if the company goes for capital lease. So, it must go for capital lease. For proposal number 2, the question is about as to whether the company must go for the operating or the capital/finance lease as per the AASB 117. As per the facts given in the question, the company will have to follow the capital/finance lease method since the majority period of the lease term is more than 75% of the total useful life of the asset. Also, this method is beneficial for the company since in this method, the company could treat the lease on the asset as loan and it would be entitled for tax deduction on this and also, it would be able to claim the depreciation on that asset which is gain tax deductible. Hence, capital/finance lease would be beneficial for Black Box. Conclusion: In respect of Proposal 1, it would be appropriate if the company goes for the cash payment at the end of the 10 th year. This is since it leads to a reduced cash outflow for the company. Further, the company must go for the cash payment at the end of the 10th year. Now, if the company goes for the payment of just $50 per shares, then there would be a cash outlay of $6,140,000 but if the company goes for the second option, then then cash outlay of the company would be $7,613,600. So, it is recommended that the company goes for the first option wherein it just has to pay $50 per share at the end of the 10 years. In respect of proposal 2, the companys sale and leaseback would be termed as a capital lease. The company if it goes for the operating lease would pay and the amount of the lease and would charge the stated expense as against the profit for each year but if it goes for the capital lease, then it would be entitled for the depreciation and also, the lease payment would be treated like a loan. So, double benefit in the case if the company goes for capital lease. So, it must go for capital lease. References: AASB 117 Leases. (2016).Charteredaccountants.com.au.

The Effects of Violence in Media on Society Today Persuasive Essay Example For Students

The Effects of Violence in Media on Society Today Persuasive Essay Is societies violence the medias fault? This is the question that has been asked since before television was in every Americans house. Of course there are the different types of media today ranging from newspapers, to on-line reports and stories. There have been arguments upon arguments about this issue, and over 3,000 studies conducted. Unfortunately there isnt one single result, there is only an array of supposed answers to this undying question. CBS president, Howard Stringer is pointing to a different scapegoat for societys violence. I come from a country that puts a lot of American movies on and has more graphic violence within its live drama on the BBC than anywhere else, and there is a lot less violence in the United Kingdom than there is here. There are 200 million guns in America, and that has a lot to do with violence. We will write a custom essay on The Effects of Violence in Media on Society Today Persuasive specifically for you for only $16.38 $13.9/page Order now He feels it has to do with gun control, which others have suggested. But there are so many violent acts, that one cant focus on the guns, just like one cant focus on the media. David Phillips, one of the men we discuss later put it perfectly, Its like watching rain fall on a pond and trying to figure out which drop causes which ripple.There have been many studies conducted on the effects of violence on children, and on the effects on society as a whole. There have been about 3,000 studies performed on this topic. Two of the most prolific studies were the UCLA Television Violence Monitoring Report, and the Mediascope, Inc. test sponsored by the National Cable Television Association. Of course there were many other studies done, but these made headlines because of their results. The UCLA study focused on all of the television media, and discovered some interesting facts from their study. Prime Time Series raised the least concern. Theatrical films raised more concern and had a lot more violence. The Saturday morning cartoons had mixed reviews. 23% of the cartoons raised concern, but that was only rating the most popular cartoons: Mighty Morphin Power Rangers, X-Men, etc. They termed the action in cartoons as Sinister Combat Violence which basically means the whole story line leads to violence.Mediascope, Inc. focused on the amount and context on cable, effectiveness of rating systems and parental advisories, and the success of anti-violent messages. They found that perpetrators go unpunished in 73% of all violent scenes, one out of four violent interactions involved the use of handguns, and premium cable channels present the highest percentage of violent programs (85%). There was more to their findings, but these were the more prevalent findings.University of Michigan psychologists Dr. Leonard Eron and Dr. Rowell Huesmann conducted a study, which continued for decades. This was conducted beginning in 1960. They took 800 eight-year-olds and found that children who watched many hours of violent television tended to be more aggressive in the playground and the classroom. They checked back with these kids 11 and 22 years later. They found the aggressive eight-year-olds grew up to become even more aggressive. They testified before congress in 1992 stating, Television violence affects youngsters of all ages, of both genders, at all socioeconomic levels and all levels of intelligence. The effect is not limited to children who are already disposed to being aggressive and is not restricted to this country.David Phillips, a scientist at the University of California in San Diego conducted a study on prizefights on television. He thought of this topic, because he felt there wasnt enough research being conducted on the copycat violence. He found that after prize fights on television, there would be about a 10 percent increase in murders for a few days afterwards. He quoted, It also seems to be the case that the kind of person killed just after the prizefight is similar to the person beaten in the prize fight.There are four major theories of television violence. The arousal theory, the social learning theory, the disinhibition hypothesis, and the catharsis hypothesis. These four hypothesis/theories are old and new conclusions to the question at hand. It is notable to see that some of these theories were stated as early as 1961. Most would have to disagree with these theories just because of the age of their births, but to most peoples surprise they still hold in the 21st century. The arousal theory is basically self-explanatory. This was theorized by P.H. Tannenbaum in 1975. .ub4a04f6c7f9e4b37fcc381444afd0841 , .ub4a04f6c7f9e4b37fcc381444afd0841 .postImageUrl , .ub4a04f6c7f9e4b37fcc381444afd0841 .centered-text-area { min-height: 80px; position: relative; } .ub4a04f6c7f9e4b37fcc381444afd0841 , .ub4a04f6c7f9e4b37fcc381444afd0841:hover , .ub4a04f6c7f9e4b37fcc381444afd0841:visited , .ub4a04f6c7f9e4b37fcc381444afd0841:active { border:0!important; } .ub4a04f6c7f9e4b37fcc381444afd0841 .clearfix:after { content: ""; display: table; clear: both; } .ub4a04f6c7f9e4b37fcc381444afd0841 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ub4a04f6c7f9e4b37fcc381444afd0841:active , .ub4a04f6c7f9e4b37fcc381444afd0841:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ub4a04f6c7f9e4b37fcc381444afd0841 .centered-text-area { width: 100%; position: relative ; } .ub4a04f6c7f9e4b37fcc381444afd0841 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ub4a04f6c7f9e4b37fcc381444afd0841 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ub4a04f6c7f9e4b37fcc381444afd0841 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ub4a04f6c7f9e4b37fcc381444afd0841:hover .ctaButton { background-color: #34495E!important; } .ub4a04f6c7f9e4b37fcc381444afd0841 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ub4a04f6c7f9e4b37fcc381444afd0841 .ub4a04f6c7f9e4b37fcc381444afd0841-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ub4a04f6c7f9e4b37fcc381444afd0841:after { content: ""; display: block; clear: both; } READ: Marshant Museum Of Art And History Essay He said exposure to television violence increases aggression because violence increases excitation, or arouses viewers (Tannenbaum Zillman, 1975). This is also being found in the recent studies, which shows the progression in the medias will to change.The social learning theory was described by Dr. Bandura. This theory says ways of behaving are learned by observing others, and that this is a major means by which children acquire unfamiliar behavior, although performance of acquired behavior will depend at least in part on factors other than acquisition (Bandura, 1973). A perfect example of this theory was when the murders occurred after the prizefights.The disinhibition hypothesis was L. Berkowitzs investigation. This hypothesis explains that television violence in certain circumstances will result in increased interpersonal aggression because it weakens inhibitions against such behavior (Berkowitz, 1962).The final theory, catharsis hypothesis was written by S. Feshbach. This theory explains that under certain conditions exposure to television violence will reduce subsequent aggression (Feshbach, 1961). What this is saying is that if someone sees a fantasy on TV, or now with technology, entertains themselves with virtual reality, that fantasy is fulfilled, which makes them not feel they have to do that in real life.So many people have discussed the topic of media effecting society, from Aristotle to the President of CBS. It has always been a question, but never as needy for an answer as now. Hopefully the government has some say in this soon, so the drama of centuries will finally be over. But that probably wont occur anytime soon.Aristotle was a big supporter of catharsis. He believed that the audience became psychologically involved with the story on stage, even though they knew it was 100% fiction. He felt when aggression climaxed with the actors, there was a catharsis in the audience, which was pleasurable to experience and left the audience cleansed, uplifted, and less likely to act violently among themselves. Sigmund Freud also felt as Aristotle did by saying, Unless people were allowed to express themselves aggressively, the aggressive energy would be dammed up, pressure would build, and the aggressive energy would seek an outlet, either exploding into acts of extreme violence or manifesting itself as symptoms of mental illness . But there is no direct evidence for this conclusion (Aronson, 1995, p. 258). President Clinton looks at it in a different light saying, for people who have never been taught to understand the consequences of their action these things can unintentionally set forth a chain reaction of ever more impulsive behavior. Hollywood figures of the 21st century blame factors such as poverty, drugs and alcohol, poor schooling, lax gun control and a general breakdown of families but not screen violence.University of Iowa professor of Journalism and Mass Communication Albert Talbott said, In the 30s, when I was a toddler, one of the things that concerned parents were comic books and the violence in them. As soon as the modern media started to develop, we have all kinds of things on how we are affecting people.Technology today isnt helping everyone to feel better about this dilemma. It is actually going to get worse before it gets better. There isnt only movies or news reports someone can watch to see violence, but also the new video game craze. Video games have become an enormous industry in the past decade. People from 4 years old to 70 years old own their own Sega Genesis or Nintendo Play Station. Of course there is a number of games to choose frombut what is the highest wanted game? None other then Mortal Combat. The name speaks for itself. Just for the record, this game consists of choosing a character, a weapon and then fighting another character until one is dead. It also is equipped with sound effects for when someone is punched or stabbed, and also shows the blood flying from the body when hit. So many studies have been done on the affects of media violence on children. Most are concerned with the results, especially parents. If the government, parents or others are so concerned with the effect of their child seeing violence on the television, maybe they should practice what they preach when Christmas rolls around. They should think twice before buying that Mortal combat III for their son. This is where it gets sticky. Parents need to draw the line between appropriate and not appropriate. It would be a nice convenience to have a rating system on the television, but parents should be aware enough of what their children are doing and watching that they are the rating system themselves.The question now is what is happening to help this situation currently? The answer is quite relieving. .u5afc22349f87da01d2788056218fd190 , .u5afc22349f87da01d2788056218fd190 .postImageUrl , .u5afc22349f87da01d2788056218fd190 .centered-text-area { min-height: 80px; position: relative; } .u5afc22349f87da01d2788056218fd190 , .u5afc22349f87da01d2788056218fd190:hover , .u5afc22349f87da01d2788056218fd190:visited , .u5afc22349f87da01d2788056218fd190:active { border:0!important; } .u5afc22349f87da01d2788056218fd190 .clearfix:after { content: ""; display: table; clear: both; } .u5afc22349f87da01d2788056218fd190 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u5afc22349f87da01d2788056218fd190:active , .u5afc22349f87da01d2788056218fd190:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u5afc22349f87da01d2788056218fd190 .centered-text-area { width: 100%; position: relative ; } .u5afc22349f87da01d2788056218fd190 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u5afc22349f87da01d2788056218fd190 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u5afc22349f87da01d2788056218fd190 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u5afc22349f87da01d2788056218fd190:hover .ctaButton { background-color: #34495E!important; } .u5afc22349f87da01d2788056218fd190 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u5afc22349f87da01d2788056218fd190 .u5afc22349f87da01d2788056218fd190-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u5afc22349f87da01d2788056218fd190:after { content: ""; display: block; clear: both; } READ: Hypotheses of the Effects of Wolf Predation Essay All of the networks are on their tippy toes so they wont get a bad name. The Entertainment Industries council, which distributes suggestions to the writers and producers of network shows and TV movies on social issues, is now meeting with writers to develop ways for dramatizing conflict without violence and showing the consequences of violence. MTV is the most risqu station on cable right now. It shows a good amount of sex and violence everyday. Usually more sex then violence, but there is a good amount of both. But at MTV, almost one out of three music videos submitted is being ruled inappropriate for broadcast.The V-Chip is another work in progress for parents. This device will be in all televisions within 5 years. It is a rating system for parents, and they can program it to cut off shows with violence or nudity, etc. This will help parents regulate what their children will watch, even when they arent around. It will be like on-line shopping, a convenience, but you still have to choose what you want to buy.Film director Oliver Stone says, Films have become more sanitized. Were moving away from reality. Were in the grip of a political correctness thats bothersome. Obviously there will be some who are concerned with the action government is taking, because media should be realistic and educating, even if it is gruesome. Some would disagree with that statement, and those are the ones taking action now. Photojournalist Assistant Professor John Kimmich Javier said, News isnt always pretty or nice. People must face that reality. People have had to face that reality, and now are taking action to stop that from continuing to be reality. Should it be stopped is the real question. What is the effect of violence in media with children compared to with adults? Children model behavior they see in the media. If they dont see the consequences of violence, it will teach them that violence doesnt cause serious harm. Adults see more violence in the media than actually exists in real life. Thats because producers believe that they have to include extraordinary violence in order to keep the viewer. When heroes use violence, children think that violence is an appropriate way to respond to problems. Children are younger, so they see things and apply that to their lives, because they are learning everything at that age. Adults look at it as the mean world syndrome in which they see how society is portrayed on TV, and they think that every neighborhood is dangerous, like shown. When in fact most neighborhoods are nothing like they are portrayed on TV. The writers and producers are exaggerating, to make it all interesting.There is also discussion of violence on TV not having any affect at all. People have seen so much, that they dont really think about the actual act occurring on screen. Hanno Hardt, a professor at J-MC School said, Its lost its shock value. Maybe 20 to 30 years ago we would have been shocked. Now, a generation later, we know that this is a violent society. And when we read about violence, it only reinforces what we know. People have become used to seeing violence on television, but this has become somewhat surreal to them. They dont think of it as reality until it happens to them. When violence happens to people or their family, they become eyewitnesses to this violence. They have personal experiences compassion sensitivity, fear. People havent lost that. We have covered a huge amount of information about the effect of violence in media on society. Did we answer the question though? I dont think we did, but I do think that the answer is making progress. We are also a lot more informed now of what exactly is in the media right now, and what studies have shown to be happening. There has always been an issue of something effecting society, and there will always be a plentitude of scapegoats. What is the actual answer though? No one seems to have it. There is a lot of gray area, but society seems to be making this more of a black and white issue. Will the government ever really take action? Does action need to be taken? Hopefully after reading this, one is more educated on the difficulty in answering these questions.

Example University of British Colombia Admission Essay Free Online Research Papers Example University of British Colombia Admission Essay The mission statement of Johnson North Secondary School has provided me the unique opportunity to gain the qualities necessary to be a successful educator. Being a senior student, I was inspired by many teachers and school staff members to give back to the school and community. I believe my experiences working with students through the JNSS mentorship and leadership programs have contributed to the fulfillment of the JNSS mission statement for reaching young students and giving them the opportunity to become exemplary citizens in and out of the school community Currently, I am an executive member of Johnson North’s Students’ Council and Fine Arts Council as well as the Grad Council Chairperson. As an executive member of all these council I work closely with students and staff to organize numerous school-wide events. I am also the Presidents of JNSS Amnesty International and one of the more recent projects that I carefully organized was the 1st Annual Amnesty International Film Festival. Apart from serving others, I also believe in education and I have had successfully finished four dynamic 1st year University level Advanced Placement courses, Biology, Psychology, Macro and Micro Economics in grade 11 and I am currently enrolled in History of Arts Advance Placement. Moreover, I believe in the value of community service and as a volunteer, I have devoted many hours to the Canadian Aids Society, Canadian Downs Syndrome Foundation, as well as the Canadian Kidney Foundation. Just before the winter break of 2006, I spearheaded the 1st Annual Amnesty International Film Festival at JNSS. The Film Festival is a week long event, where two films related to human rights were featured each day in our school gallery. The executives worked closely with the regional director of Amnesty International of Canada and with the support of the staff from the school and the dedication of club members and volunteers, the events was a tremendous success. Through our work, we were able to give students from all grades an opportunity to learn about human rights and make them understand the values and rights that all people are entitled to. Political and social issues such as those facing Tibetans in China, the aftermath of the chemical explosion in Bhopal, India, conflict diamonds in African nations, and the travesty in North Korea, were some of the topics that were covered at our film festival. What fascinated me was the sense of good-will that radiated amongst the students. In a concerted effort to create awareness in our community, we were able to ensure the tremendous success of the event. I am always striving to help other students create and achieve their goals. My leadership at Johnson north has always been accomplished through taking action and helping others. I have been involved in my school’s Grade 8 Mentoring program where senior students are assigned five juniors and I acted as a positive role model for the elementary students in making the leap to high school. My genuine concern for the world’s problem has inspired me to become a high school science and social studies teacher. My endeavor to assist students has not only helped them to reach their full potential, but also allowed me to continue my life’s ambition to be a positive influence on my society and the University of British Colombia.

Are Video Games Art - Research Paper Example ies which immerses the player engaging them deeply in the real life problems they face like depression and living in an abusive home, or the Shadow of Colossus wherein symbolism comes into play and all the characters designed with complex details, the list of the games invoking a personal response from a player are endless. Aaron Smuts in his article â€Å"Are videogames Art?† uses the examples of games like ‘Max Payne’ (2001), ‘Halo’ (2001) and ‘Tom Clancy’s Splinter Cell (2002) to explain how videogames posses the ‘aesthetic potential’ which engages the player implying it is a promising art. ‘Max Payne’ has a very detailed plot and touches upon the story of an unprincipled cop who sets out to seek revenge of the death of his wife and his child. The game engrosses the player as he controls the advances of the character; dealing with different conspiracies weaved in the screenplay, hungry for revenge. Similarly, Halo involves many twists in the plot and the player enjoys slowly uncovering where the army as crash landed. The game Splinter Cell has been designed to trigger a feeling of tension in the player as he hides around from the lurking danger. Most of the game consists of hiding around in suspense. The game has the immense quality of having detailed maneuvers of different character, remarkable lighting effects and a prolific shadow play. All these details along with the suspense ridden story involving the player deeply are nothing a work of art. Smuts states that the games are the products of sophisticated technology and the graphics are close to real life, though it can not match the greatness of artworks in the history but it surely agrees with the definition by invoking some emotions in the player (Smuts 2005). Videogames to be determined as art should possess the quality of emotionally involving the players. The game ‘Alice: Madness Returns’ tells a story about a girl who sees her whole family die as a result of fire and leaving

Horses in Han Dynasty China Research Paper Example | Topics and Well Written Essays - 2500 words

Horses in Han Dynasty China - Research Paper Example However, one wonders why horse carvings and sculptures were a common feature of the Han dynasty? The depiction of the horse on the tombs translates to a critical role that the horse played in the afterlife. A superficial view of the issue may assume that the horse was just an additional object that accompanied the dead to the afterlife. However, a deeper analysis of the religious set-up of the Han dynasty provides highlights on the critical role played by the horse in guiding and protecting people in the afterlife. This paper will analyze the belief system of the Han dynasty and the attributes of people whose tombs had horse carvings. History and Religion of the Han Dynasty The Han dynasty emerged in 207 B.C.E as a successor of the Qin dynasty. The Han dynasty found a united Chinese society from the efforts of its immediate predecessor. This dynasty lasted for the longest time in China thriving in unity. However, the dynasty faced a division in the years that followed. Initially, the western Han had political strength. Upon its collapse, the eastern side rose to take its place. The Han dynasty had an intense culture and architectural designs evident from archeological and historical evidence. The society practiced agriculture and the war. In addition, history reveals that the society domesticated horses. The people of the Han dynasty had strong beliefs about life beyond death.... In the ritual ceremonies that sought to unite the dead bodies with the immortal spirits, people offered sacrifices. The people opined that sacrificial goods were critical because they would be useful in the afterlife. The dead received a decent and well-designed burial tomb, an honorable place where they could spend their eternity. Attempts of Describing the Tomb Architecture Different reserchers have tried to unravel the relevance of the horse. The mausoleum of an emperor played the role of his palace in the afterlife. The horse was one of the common sculptures in most of the tombs.The people associatedthe horse with the potential of guiding the deceased emperor in the journey towards the next phase of life. Just as a horse would guide and protect an emperor in real life, the Han dynasty believed that the horse had the power to do the same in the spirit world. An emperor going to the next life without a horse would lack a basic aspect in the next world. In addition, horses were the symbols of wealth and power in the afterlife just as they were among the living.4 The Han dynasty mausoleums had details of a complete palace with different rooms designated to palace servants such as guards, dancers, cooks, and the burial chambers.5 The structures had detailed the architecture and the construction took a long time. The people’s beliefs and convictions of life after death compelled society to give up some people for servitude in the spirit world. However, in the Han dynasty, carvings replaced the sacrifice of people. Mausoleums proved to be places of great significance for the Chinese people. From the archeological records of excavated

Identifying Problems When Obtaining Population Parameters

Identifying Problems When Obtaining Population Parameters We estimate population parameters, such as the mean, based on the sample statistics. It is difficult to get a precise value or point estimation of these figures. A more practical and informative approach is to find a range of values in which we expect the population parameters will fall. Such a range of values is called a confidence interval. 1. CONFIDENCE INTERVAL Definition The confidence interval is a range of values constructed from sample data so that the population parameter is likely to occur within that range at a specified probability. The specified probability is called the level of confidence. The shape of the probability distribution of the sample mean allows us to specify an interval of specific probability that the population mean,  µ, will fall into. 1.1 Large Sample Or Standard Deviation Is Known Case 1: The standard deviation à Ã†â€™ is known; or It is a large sample (i.e. at least 30 observations). The Central Limit Theorem states that the sampling distribution of the sample means is approximately normal. We can use the tables in the Appendix to find the appropriate Z value. Key Points The standard normal distribution allows us to draw the following conclusions: 68% of the sample means will be within 1 standard deviations of the population mean,  µ. 95% of the sample means will be within 1.96 standard deviations of the population mean,  µ. 99% of the sample means will lie within 2.58 standard deviations of the population mean. These intervals are called the confidence interval. The standard deviation above (i.e. the standard error) is referring to the standard deviation of the sampling distribution of the sample mean. Locating 0.475 in the body of the table, read the corresponding row and column values, the value is 1.96. Thus, the probability of finding a Z value between 0 and 1.96 is 0.475. Likewise, the probability of being in the interval between -1.96 and 0 is also 0.475. When we combine these two, the probability of being in the interval of -1.96 to 1.96 is therefore 0.95. 1.1.1 How do you compute a 95% confidence interval? Assume our research involves the annual starting salary of business graduates in a local university. The sample mean is $39,000, while the standard deviation of the sample mean is $250. Assume our sample contains more than 30 observations. The 95% confidence interval is between $38,510 and $39,490. Found by $39,000 +/- 1.96($250) In most situations, the population standard deviation is not available, so we estimate it as follows: (Standard Error) Conclusions: 95% confidence interval 99% confidence interval Confidence interval for the population mean (n > 30) Z depends on confidence level Example 1 The Hong Kong Tourist Association wishes to have information on the mean annual income of tour guides. A random sample of 150 tour guides reveals a sample mean of $45,420. The standard deviation of this sample is $2,050. The association would like answers to the following questions: (a) What is the population mean? The best estimate of the unknown population value is the corresponding sample statistic. The sample mean of $45,420 is a point estimate of the unknown population mean. (b) What is a reasonable range of values for population mean? The Association decides to use the 95% level of confidence. To determine the corresponding confidence interval, we use the formula: The endpoints would be $45,169 and $45,671 and they are called confidence limits. We could expect about 95% of these confidence intervals contain the population mean. About 5% of the intervals would not contain the population mean annual income, i.e. the  µ. Figure 2 Probability distribution of population mean 1.2 Small Sample Or Standard Deviation Is Unknown Case 2: The sample is small (i.e. less than 30 observations) or, the population standard deviation is not known. The correct statistical procedure is to replace the standard normal distribution with the t distribution. The t distribution is a continuous distribution with many similarities to the standard normal distribution. 1.2.1 Standard normal distribution versus t distribution Figure 3 Z distribution versus t distribution The t distribution is flatter and more spread out than the standard normal distribution. The standard deviation of the t distribution is larger than the normal distribution. Confidence interval for a sample with unknown population mean, à Ã†â€™. The confidence interval is Assume the sample is from a normal population. Estimate the population standard deviation (à Ã†â€™) with the sample standard deviation (s). Use t distribution rather than the Z distribution. Example 2 A shoe maker wants to investigate the useful life of his products. A sample of 10 pairs of shoes that had been walked for 50,000 km showed a sample mean of 0.32 inch of sole remaining with a standard deviation of 0.09 cm. Constructing a 95% confidence interval for the population mean, would it be reasonable for the manufacturer to conclude that after 50,000 km the population mean amount of sole remaining is 0.3 cm? Assume the population distribution is normal. The sample standard deviation is 0.09 cm. There are only 10 observations and hence, we use t distribution Estimation: = 0.32, s = 0.09, and n = 10. Step 1: Locate t by moving across the row for the level of confidence required (i.e. 95%). Step 2: The column on the left margin is identified as df. This refers to the number of degrees of freedom. The number of degree of freedom is the number of observations in the sample minus the number of samples, written n-1.(i.e. 10-1=9). Step 3: Confidence Interval = The endpoints of the confidence interval are 0.256 and 0.384. Step 4: Interpretation the manufacturer can be reasonably sure (95% confident) that the mean remaining tread depth is between 0.256 and 0.384 cm. Because 0.3 is in this interval, it is possible that the mean of the population is 0.3. 2. CHOOSING AN APPROPRIATE SAMPLE SIZE The necessary sample size depends on three factors: Level of confidence wanted: To increase level of confidence, increase n. Margin of error the researcher will tolerate: To reduce allowable error, increase n. Variability in the population being studied: For a more widely dispersed sample, increase n. We can express the interaction among these three factors and the sample size in the following formula: Sample size for estimating the population mean, Note: n: Sample size Z: Standard normal value S: Estimate of population standard deviation E: Maximum allowable error Example 3 An accounting student wants to know the mean amount that independent directors of small companies earn per month as remuneration for being a director. The error in estimating the mean is to be less than $100 with a 95% level of confidence. The student found a report by the government that estimated the standard deviation to be $1000. What is the required sample size? Maximum allowable error, E, is $100. Value of Z for a 95% level of confidence is 1.96, and the estimate of the standard deviation is $1000. Substitute into , we get n = [ (1.96) (1000) ] 2 = 19.62 = 384.16 100 The sample of 385 is required to meet the requirements. If the students want to increase the level of confidence, e.g. 99%, this requires a larger sample. Z = 2.58, so n = [ (2.58) (1000) ] 2 = 25.82 = 665.64 100 Sample = 666 3. WHAT IS A HYPOTHESIS? Definitions Hypothesis is a statement about a population parameter developed for the purpose of testing. Hypothesis testing is a procedure based on sample evidence and probability theory to determine whether the hypothesis is a reasonable statement. In statistical analysis, we always make a claim about the population parameters, i.e. a hypothesis. We collect data and then use the data to test the assertion. 4.1 Five-Step Procedure For Testing A Hypothesis Figure 4 How to test a hypothesis 4.1.1 Step 1: State null hypothesis (H0) and alternative hypothesis (H1) The first step is to state the hypothesis being tested. It is called the null hypothesis. We either reject or fail to reject the null hypothesis. Failing to reject the null hypothesis does not prove that H0 is true. The null hypothesis is a statement that is not rejected unless our sample data provide convincing evidence that it is false. The alternative hypothesis is a statement that is accepted if the sample data provide sufficient evidence that the null hypothesis is false. Example 4 A journal has disclosed that the mean age of commercial helicopters is 15 years. A statistical test of this statement would first need to determine the null and the alternate hypotheses. The null hypothesis represents the current or reported condition. It is written H0:  µ = 15. The alternate hypothesis is that the statement is not true, i.e. H1:  µ à ¢Ã¢â‚¬ °Ã‚   15. 4.1.2 Step 2: Select a level of significance The level of significance is the probability of rejecting the null hypothesis when it is true. A decision is made to use the 5% level, 1% level, 10% level or any other level between 0 and 1. We must decide on the level of significance before formulating a decision rule and collecting sample data. Type I error: Rejecting the null hypothesis, H0, when it is true. Type II error: Accepting the null hypothesis when it is false. Example 5 Suppose AA Watch Ltd has informed bracelet suppliers to bid for contract on the supply of a large amount of bracelets. Suppliers with the lowest bid will be awarded a sizable contract. Suppose the contract specifies that the watch producers quality-assurance department will take samples of the shipment. H0: The shipment of bracelet contains 6% or less substandard bracelets. H1: More than 6% of the boards are defective. A sample of 50 bracelets received August 2 from BB Metals Ltd revealed that four bracelets, or 8%, were substandard. The shipment was rejected because it exceeded the maximum of 6% substandard bracelets. If the shipment was actually substandard, the decision to return the bracelets to the supplier was correct. However, suppose the four substandard bracelets selected in the sample of 50 were the only substandard bracelets in the shipment of 4,000 bracelets. Then only 1/10 of 1% were defective (4/4000 = 0.001). In that case, less than 6% of the entire shipment was substandard and rejecting the shipment was an error. We may have rejected the null hypothesis that the shipment was not substandard when we should have accepted the null hypothesis. By rejecting a true null hypothesis, we committed a Type I error. AA Watch Ltd would commit a Type II error if, unknown to the company an incoming shipment of bracelet from BB Metals Ltd contained 15% substandard bracelets, yet the shipment was accepted. How could this happen? Suppose two out of the 50 bracelets in the sample (4%) tested were substandard, and 48 out of the 50 were good bracelets. As the sample contained less than 6% substandard bracelets, the shipment was accepted but it could be purely by chance that the 48 good bracelets selected in the sample were the only acceptable ones in the entire shipment. In conclusion: Null Hypothesis Accepts H0 Rejects H0 H0 is true Correct decision Type I error H0 is false Type II error Correct decision 4.1.3 Step 3: Select the test statistics There are many test statistics. In this chapter, we use both Z and t as the test statistic. Definition A test statistic is a value, determined from sample information, used to determine whether to reject the null hypothesis. In hypothesis testing for the mean ( µ) when à Ã†â€™ is known or the sample size is large, the test statistic Z is computed by: The Z value is based on the sampling distribution of , which follows the normal distribution when the sample is reasonably large with a mean () equal to  µ, and a standard deviation , which is equal to . We can thus determine whether the difference between and  µ is statistically significant by finding the number of standard deviations is from  µ, using the formula above. 4.1.4 Step 4: Formulate the decision rule Definition A decision rule is a statement of the specific conditions under which the null hypothesis is rejected and the conditions under which it is not rejected. The region or area of rejection defines the location of all those values that are so large or so small that the probability of their occurrence under a true null hypothesis is rather remote. The area where the null hypothesis is not rejected is to the left of 1.65. The area of rejection is to the right of 1.65. A one-tailed test is being applied. The 0.05 level of significance was chosen. The sampling distribution of the statistic Z is normally distributed. The value 1.65 separates the regions where the null hypothesis is rejected and where it is not rejected. The value 1.65 is the critical value. The critical value is the dividing point between the region where the null hypothesis is rejected and the region where it is not rejected. Figure 5 Area of rejection for the null hypothesis 4.1.5 Step 5: Make a decision The final step in hypothesis testing is computing the test statistic, comparing it to the critical value, and making a decision to reject or not to reject the null hypothesis. Based on the information, Z is computed to be 2.34, the null hypothesis is rejected at the 0.05 level of significance. The decision to reject H0 was made because 2.34 lies in the region of rejection, i.e. beyond 1.65. We would reject the null hypothesis, reasoning that it is highly improbable that a computed Z value this large is due to sampling variation. Had the computed value been 1.65 or less, say 0.71, the null hypothesis would not be rejected. It would be reasoned that such a small computed value could be attributed to chance. Example 6 A large car leasing company wants to buy tires that average about 60,000 km of wear under normal usage. The company will, therefore, reject a shipment of tires if tests reveal that the life of the tires is significantly below 60,000 km on the average. The company would be glad to accept a shipment if the mean life is greater than 60,000 km. However, it is more concerned that it will have sample evidence to conclude that the tires will average less than 60,000 km of useful life. Thus, the test is set up to satisfy the concern of the car leasers that the mean life of the tires is less than 60,000 km. The null and alternate hypotheses in this case are written H0:  µ à ¢Ã¢â‚¬ °Ã‚ ¥ 60,000 and H1:  µ In this problem, the rejection region is pointing to the left, and is therefore in the left tail. Summary: If H1 states a direction, we use a one-tailed test. If no direction is specified in the alternate hypothesis, we use a two-tailed test. Figure 6 One-tailed test 5. TESTING FOR POPULATION MEAN WITH KNOWN POPULATION STANDARD DEVIATION 5.1 Two-tailed Test ABC Watch Ltd manufactures luxury watches at several plants in Europe. The weekly output of the Model A33 watch at the Swiss Plant is normally distributed, with a mean of 200 and a standard deviation of 16. Recently, because of market expansion, mechanisation has been introduced and employees laid off. The CEO would like to investigate whether there has been a change in the weekly production of the Model A33 watch. To put it another way, is the mean output at Swiss Plant different from 200 at the 0.01 significant levels? 5.1.1 Step 1: State null hypothesis and alternate hypothesis The null hypothesis is The population mean is 200. H0:  µ = 200. The alternate hypothesis is The mean is different from 200. H1:  µ à ¢Ã¢â‚¬ °Ã‚   200. 5.1.2 Step 2: Select the level of significance The 0.01 level of significance is used. This is ÃŽÂ ±, the probability of committing a Type I error, and it is the probability of rejecting a true null hypothesis. 5.1.3 Step 3: Select the test statistic The test statistic for the mean of a large sample is Z. Figure 7 Normalise the standard deviation 5.1.4 Step 4: Formulate the decision rule The decision rule is formulated by finding the critical values of Z from Appendix D. Since this is a two-tailed test, half of 0.01, or 0.005, is placed in each tail. The area where H0 is not rejected, i.e. area between the two tails, is 0.99. Appendix D is based on half of the area under the curve, or 0.5. Then 0.5 0.005 is 0.495, so 0.495 is the area between 0 and the critical value. The value nearest to 0.495 is 0.4951. Then read the critical value in the row and column corresponding to 0.4951. It is 2.58. Decision rule: Reject H0 if the computed Z value is not between -2.58 and +2.58. Do not reject H0 if Z falls between -2.58 and +2.58. Figure 8 Two-tailed test 5.1.5 Make a decision and interpret the result Compute Z and apply the decision rule to decide whether to reject H0. The mean number of watches produced weekly for last year is 203.5. The standard deviation of the population is 16 watches. Because 1.55 does not fall in the rejection region, H0 is not rejected. We conclude that the population mean is not different from 200. So we would report to the CEO that the sample evidence does not show that the production rate at the Swiss plant has changed from 200 per week. The difference of 3.5 units between the historical weekly production rate and the mean number of watches produced weekly for last year can reasonably be attributed to sampling error. Figure 9 Rejection regions for the two-tailed test So did we prove that production rate is still 200 per week? No! Failing to disprove the hypothesis that the population mean is 200 is not the same thing as proving it to be true. 5.2 P-value In Hypothesis Testing Definition P-value is the probability of observing a sample value as extreme as, or more extreme than, the value observed, given that the null hypothesis is true. How confident are we in rejecting the null hypothesis? This approach reports the probability of getting a value of the test statistic at least as extreme as the value actually obtained. This process compares the probability called the P-value, with the significant level. If the P-value If the P-value > significant level, H0 is not rejected. A very small P-value, such as 0.0001, indicates that there is little likelihood the H0 is true. If a P-value of 0.2033 means that H0 is not rejected, there is little likelihood that it is false. Figure 10 P-value P-value Interpretation Less than 0.1 Some evidence that H0 is not true Less than 0.05 Strong evidence that H0 is not true Less than 0.01 Very strong evidence that H0 is not true Less than 0.001 Extremely strong evidence that H0 is not true The probability of finding a Z value of 1.55 or more is 0.0606, found by 0.5 0.4394. The probability of obtaining an greater than 203.5 if  µ = 200 is 0.0606. To compute the P-value, we need to be concerned with the region less than -1.55 as well as the values greater than 1.55. The two-tailed P-value is 0.1212, found by 2(0.0606). The P-value of 0.1212 is greater than the significance level of 0.01, so H0 is not rejected. Chapter Review The Central Limit Theorem states that the sampling distribution of the sample means is approximately normal. The standard error refers to the standard deviation of the sampling distribution of the sample mean. We use t distribution when the sample is less than 30 observations and the population standard deviation is not known. The necessary sample size depends on 1) level of confidence wanted ; 2) margin of error the researcher will tolerate; 3)variability in the population.   By rejecting a true null hypothesis, we committed a Type I error. We would reject the null hypothesis when it is highly improbable that a computed Z value this large is due to sampling variation. What You Need To Know Confidence interval: A range of values constructed from sample data so that the population parameter is likely to occur within that range at a specified probability. Hypothesis: A statement about a population parameter developed for the purpose of testing. Hypothesis testing: A procedure based on sample evidence and probability theory to determine whether the hypothesis is a reasonable statement. Critical value: The dividing point between the region where the null hypothesis is rejected and the region where it is not rejected. P-value: The probability of observing a sample value as extreme as, or more extreme than, the value observed, given that the null hypothesis is true. Work Them Out 1.
