World Wild foundation advertisement Research Paper

World Wild foundation advertisement - Research Paper Example It is virtually in all areas of society. Nonetheless, violence is highly depicted in advertisements, from advertising household commodities to industrial machinery. In addition, violence is not only expressed physically, it is also expressed socially and psychologically. All these forms of violence are exhibited through advertisements. Nonetheless, media stakeholders have tried dealing with this issue (Hamilton, 1998). This paper will consider violence in relation to advertisement and how it affects children and women. The significance of violence in television interference impact is highlighted by proof that violence is common in television programs. Nonetheless, while some advertisers avoid programs containing violent content, other advertisers do not air violent programs. Bushman conducted research on the impact of a violent content on memory for advertisements not containing violence. Bushman concluded that while violent television programs may cause enraged thoughts, this may af fect the processing of nonviolent advertisement programs. Violent advertising affect memory of individuals, mostly children and women. ... Also, violence is mostly recalled when a person is placed in a violent environment. An explanation for this is that violence in a violent environment makes violence associated concepts more within reach (National Television Violence Study 2, 1998). The attack on the Twin Towers instigated negative impact on the economy of the country and also had a tremendous effect on world economies. Therefore, advertisements related to the Twin Towers have negative effects to women and children. The analysis of the World Wild foundation advertisement takes into account children and women as the targets of the advertisement. This considers the objective of the advertisement and the view of the advertising content or intention of the advertiser. The analysis also looks at the children and women as advertising resource. This can stimulate impacts at the level of thought, behavioral or affective level. The analysis also may refer to women and children as receivers of advertising. This notion is linked with the habits and behavior of intake of advertising by the women and children (National Television Violence Study 2, 1998). The World Wild foundation advertisement does not consider women and children viewers of the advertisement. This is because there is a person pointing a gun at a child. This will make women and children have a negative view of the advertisement. This is because children will view themselves as targets of violence and women will have a negative attitude due to their care giving nature. The city of New Jersey lost the largest number of people after New York City. Over 90 different nations lost nationals in the World Trade Centre attacks.

The U.S. economy Essay Example for Free

The U.S. economy Essay and one that some economic analysts say may persist for at least another year. The unemployment rate has risen to levels not seen in over 20 years. The current unemployment rate is at 8% and is expected to rise further. The inflation rate is -2. 4 percent, meaning that overall, prices are falling. Recommendation Currently our economy is in deep recession and one of the challenges we have is the unemployment rate, which has risen to levels not seen in over 20 years. The current unemployment rate is at 8% and is expected to rise further. Also we have one more challenge of inflation of -2. 4 percent – it means that our economy is in deflation as overall prices are reducing. After having a detail discussion with my colleagues, economic consultants and economic advisors I have following recommendation for President of the United States to bring the economy back on track:- I believe and agree with my colleagues â€Å"Raymond Burke† and â€Å"Allison Tanney† advice that Government/Congress should use Expansionary fiscal policy along with Expansionary monetary policy. This will be accomplished by increasing aggregate expenditures and aggregate demand through an increase in government spending (both government purchases and transfer payments) or a decrease in taxes. I also agree with by colleague â€Å"Patricia Lopez† that Fed should leave interest rates alone, but strongly sell bonds and raise the bank reserve requirement. This will increase the money supply and decrease interest rates. This is accomplished by buying U. S. Treasury securities in the open market, lowering the discount rate, and reducing reserve requirements. In these difficult economic times, I would recommend that the President should increase in government purchases, a decrease in taxes, and/or an increase in transfer payments to close a recessionary gap, stimulate the economy, and decrease the unemployment rate. I disagree with the colleague â€Å"Kathy Lee† that the President should consider to raise taxes and reducing government spending, since this will have negative impact on our current economy as this will not help us to control unemployment. Finally, I recommend the President to use Expansionary fiscal policy along expansionary monetary policy to help our economy to recovery current deep recession.

The Chrysalids, by John Wyndham :: essays research papers

The Chrysalids, by John Wyndham Background: John Wyndham, born in 1903, tried more than four careers before starting to write short stories in 1925. The Chrysalids was written in 1955. Outline of the Book: Thousands of years after our time, the world faced something known as Tribulation, when civilization was almost completely wiped out and had to be started over, with new rules and laws. Humans beings born as â€Å"deviants†, missing an attribute that normal humans would have, is considered a blasphemy towards God. David, a young man whose father is in charge of seeking out deviants in his community, discovered that he, along with a few other young adults, can communicate to one another through their minds and what they call â€Å"thought shapes†. For a long while they’ve hidden their secret talents, but as rules get tighter and tighter they know it’s only a matter of time until they’re discovered. Theme(s): tolerance, religion Criticisms (Unfavourable): Near the end of the book the dialogue becomes more rhetorical than the rest of the book. This isn’t really a problem, but can become slightly confusing at times. The best option would be to read this part slowly and carefully in order to understand what the message is. Criticisms (Favourable): Very original, intelligent plot. Well-written characters that aren’t two dimensional and who make human decisions (David’s father, who may seem like a cruel man but who is really just doing what he was brought up to believe is right). Comparison: â€Å"The House of the Scorpion†, â€Å"The Stepford Wives† (book) These two books also deal with people who are not as â€Å"real† as typical human beings, such as robots or clones Quotations: â€Å"Clearly there must be a mistake somewhere. Surely having one very small toe extra—well, two very small toes, because I supposed there would be one to match on the other foot—surely that couldn’t be enough to make her ‘hateful in the sigh of God†¦Ã¢â‚¬â„¢?

Book Club Novel Study vs. Conventional Core Novel Study

Book Club Novel Study vs. Conventional Core Novel Study Although the Book Club approach and the conventional novel study approach are group discussion oriented, the Book Club method is a more efficient way of extracting thorough analysis from multiple perspectives. In the Book Club approach, students are forced to read because we are constantly being evaluated. During discussions, the teacher is always walking around evaluating groups.My group especially was always prepared because of the fear of not getting a good mark due to being unprepared. The fact that we are constantly being evaluated develops pressure on the students, which forces them to prepare for the discussion the night before. Preparing the night before allows for a more in depth analysis. If everyone is prepared with notes and questions the discussion will be much more interesting because everyone brings something to the table.Which in essence allows a much more effective and efficient discussion. However, with the con ventional approach you have majority of the classroom not participating and not being involved in the discussions. In last year’s English class, there were a set number of students who were always participated and then the majority of the class not effectively participating. Because the traditional method is a more broad discussion and there aren’t specific roles for students to carry out students are not pressured to be prepared.I can use myself as an example, last year there would be times I wouldn't read the sections assigned and because of this I found myself not participating and engaging in class discussions. The Book Club approach consists of continuous evaluation and a certain set of tasks like discussion leading that force students to consistently engage in discussions. The evaluation creates pressure, causing students to be prepared and contribute during scheduled conferences. On the other hand, the traditional method of novel study is not as effective.The st udents are not pressured because they feel as if they are not being evaluated on a regular basis. So students take advantage of this and feel their input is not necessary and rest of the class will carry their weight. To conclude, both approaches involve students participating and engaging in a group discussion but the Book Club approach has a higher efficiency in terms of each students input during discussions in comparison to the conventional core study.

Representations of Men in Advertising

What is a man? This question may be odd to hear, but it's a question that is answered constantly by advertisers in print ads and television commercials, all with different approaches. But he question the advertises are asking is â€Å"What images of men will sell my product? â€Å". There is the image of the rebel, the masculine heroes, the violent or aggressive man, or the classic ‘Gentleman'. In recent years we see advertisers moving closer towards the image of the ‘modern man'. The modern man, also known as the metro-sexual man, can be defined as well groomed, health and body conscious, and well dressed. The deconstruction of the two advertisements, Ralph Lauren and Michelob Ultra, accentuate this image and show its influence on the male audience. The Michelob Ultra advertisement preys on the modern mans body image perceptions, and uses them to create a desire for their product. The ad depicts an athletic swimmer, of whom we are to believe consumes the product, getting out of the pool, a picture of the product, and the heading â€Å"Lose the Carbs. Not the taste†. The caption â€Å"†¦ this is your fountain of youth† insinuates that this product will keep you healthy youthful, while being able to enjoy alcohol. There is a famous quote from Edgar A. Schoaff that reads, â€Å"Advertising is the art of making whole lies, out of half truths†. This ad from Michelob is a perfect example of this. In reality, the beer still contains carbs, almost the same amount as regular beer, but using an almost irrelevant idea of low carbs and transforming it into a, for lack of a better term, ‘healthy' beer. This misleading idea forces easily persuaded body conscious males to believe in their product. Ultimately, this kind of advertising manipulates males thoughts and plants false images of an unattainable body. The ‘modern man' look has grown increasingly more popular due to advertisers push to make men obsessing over their own body image. The advertisement for Ralph Lauren targets these image wise men and positions themselves as the ‘right' image. The ad is almost completely in black and white, with just the brand name, â€Å"Ralph Lauren† standing out in the background. The contrast makes for a striking and eye catching advertisement, with a hint of panache. It depicts three young men hurdling over a tennis net, boasting their clothes and style. Thre three men are racing, playing off men's stereotypical competitiveness and pursuit to be the best. The ad suggests that Ralph Lauren will help you get there. David Foster Wallace sums this up with his quote, â€Å"It did what all ads are supposed to do: create an anxiety relievable by purchase†. The anxiety is the endeavour to be the best and the brand will help you in that objective. Therefore, this ad boasts itself as an image of what the modern man should strive for. As a result of the many advertising archetypes presented and beliefs about normalcy, young men are growing up being bombarded by different representations and images of males and find it impossible to not fall victim of them. Young men are often enticed to emulate what they see on the television, hear on the radio or read on a newspaper ad. The allure of the lifestyle presented in advertising is most often great enough to coax the consumer to buy into it. These facts are supported by the aforementioned advertisements. Both similar in regards to target audiences, and give impressions of the modern man. One of perfect body aspirations, and the other a pursuit for the perfect look. But both simultaneously give people ambitions to be the modern man.

Gone are the yearss when curates. shepherds. priests. bishops and the likes knew each and every member of his church personally. Churchs are no longer merely families. grades are offered. histories are kept. people are wedded and the public assistance of members is accompanied to. Imagine what a professional football squad would be like without a regimen of pattern drills? Now take away their playbook and participant statistics.

They might really win a game or two. but in the long tally. this squad is doomed. This illustration is to drive place the point of why any organisation demands to analyze the being and effectivity of its direction systems. The universe is going Information and technologically based. For this ground. Management Systems have been introduced into assorted industries runing from the educational to the wellness sector and even into agribusiness amongst other things. A direction Information System is a system to change over informations from internal and external beginnings into information. in an appropriate signifier. to direction at all degrees in all maps to enable them to do timely and effectual determinations for planning. directing and commanding the activities for which they are response. The Church is non excluded from these industries. The Church Management and Information System is a system for churches to pull off their operations expeditiously and consistently ( Wikipedia. 2012 ) . It is besides a specialised package that assists churches in organisation and mechanization of day-to-day operations. Current System King’ong’o PCEA uses a to the full manual system of maintaining all its records. Fiscal records. which need a batch of transparence and answerability. are kept in manus written paperss. A batch of minutess affecting money are carried out by the parish. For case. pull offing contributions from church members and sympathizers. pull offing offerings and tithes by members. seeking and pull offing hard currency disbursals by the church etc. All the fiscal inside informations are kept manually which is cumbrous and prone to errors. Defects can easy happen with this system doing it non dependable ad naming for a redress. The church besides needs to maintain path of activities that take topographic point in the church every twenty-four hours. For case. seeking past activities by the parish. freshly integrated church activities. testimonies. new testimonies. pull offing activity types etc. Other things besides need record maintaining like pull offing people and the issue of rank to the church. In this instance. records for new members. new converts. First-timers etc. necessitate to be kept. With the bing system. seeking the records is cumbrous and time-consuming. Records of groups and sections associating to the church ought to be maintained for the benefit of the church. Department activities need to be decently recorded and updated consequently and retrieved as per the church direction demands. Retrieval of these records is difficult since they are kept in files in written paperss. Recovering a record involves perusing through a immense figure of files. A batch of clip is wasted recovering manual records. Reports need to be kept and retrieved as per the demands of church directors. For case. attending studies for church members. fiscal studies after a certain sum of clip. rank inside informations study etc. Reports for the bing system involves traveling through relevant records manually and coming up with the needed studies. This is cumbrous and time-wasting. Proposed system A package system is proposed to replace the manual system for maintaining records. A fiscal faculty is used to automatize fiscal record maintaining and retrieval. A database is used to hive away fiscal inside informations of the parish. An interface is provided for interacting with the database whereby a user can compose into the database and they can question the database as per their demands. Financial information maintaining is made easy through this package solution and besides seeking of fiscal inside informations made even more easier through the proposed package. Through an Activity faculty. day-to-day activities in the church are stored in a database which is updated to encompass new activities. A platform for pass oning to the database is offered where the user ( authorized ) interacts with the database ( writes into the database and queries the database ) . With the new system. activities in the church are recorded in database tabular arraies and can ever be retrieved with their several day of the months via questions. A batch of valuable clip is saved through the new system. Departments are automated utilizing a section faculty. This faculty offers an interface for come ining inside informations of involvement into the database. Since departmental inside informations are of premier importance in every bit far as the church is concerned. proper inside informations associating to the Parish ought to be kept and retrieved with easiness. The user hunts records associating to a section of involvement with a batch of easiness through the interface provided by the departments’ faculty. The awkwardness with the manual system would therefore be alleviated by the proposed package solution. Report coevals with the proposed system is automated ( made alarmingly easy ) through the Report faculty. This is done through incorporating database SQL capabilities into the package. Fiscal studies. activity studies etc. can be generated through merely pressing a button which will give prompts to the user on the studies they want. The tyre and the ennui associated with perusing through records to pull a study are wholly eradicated through the proposed package solution. The assorted faculties defined with different functionalities are integrated to organize a harmoniously and efficaciously working package to go to the manual job of maintaining Parish records. Problem statement Keeping records manually is utterly cumbersome since it involves handwriting or typing every item of involvement. Managing physical records is cumbrous since storage infinite is needed and they can be affected by natural fortunes such as plagues and unfavourable environment. Additionally. roll uping studies for physical ( manual ) records is non an easy undertaking since it involves walking through all records and pulling information of involvement. A batch of forces is needed to maintain records for the different church sections and keep them and this comes with higher costs due to rewards for the record keepers. King’ong’o PCEA Parish is one of the victims of the above mentioned jobs which the proposed system wishes to supply a redress for. Scope The ensuing Integrated Parish Management Solution will be in English and will include subsystems and functionality to back up the followers: FINANCIAL MODULE The Financial Module comes with the right tools to help in the church in direction of the followers: Contributions and Contributions Offerings and tithes Cash Expense and lots Donations direction is a cardinal country in this faculty as single contributions by members and linked to the major contributions which help to reply inquiries like ( How much has being released from a peculiar contribution proclamation ) The offering direction allows the church to enter any sort of offering type. therefore non curtailing you to any signifier of predefined construction.

BACK-UPS The importance of making a backup can neer be emphasized plenty. The parish’s IT section will be responsible for implementing modus operandis for regular backup of organization’s informations. In the event of a possible system clang. it will be clip -consuming and hard to retrace the database. For frequent plan usage I therefore recommend that backups are taken daily. Storing backups Backups can be taken to the hard-drive. a shared booklet in the web or to external media such as USB pen thrusts. Zip drives or similar. I recommend that you store at least one complete backup offprint from the computing machine in instance of catastrophe. Provision for external difficult thrust storage has been integrated in the financials. Justification A package solution for the named job would be really appropriate compared to the bing system. The undermentioned grounds justify the demand for the package solution: ?The tyre associated with doing records manually and keeping them would be alleviated.

The package would offer an first-class interface to interact with the Parish database ( come ining new inside informations and updating bing inside informations to guarantee unity ) . As a consequence of the easiness of entering and updating informations. the job of tyre associated with informations care would be eradicated by the proposed Integrated Parish Management solution. ?Parish forces cost would travel down every bit a consequence of execution of the Proposed Integrated Parish Management Software. With the old system. a batch of forces is required to maintain and keep Parish records which culminates in higher Parish running costs. The Proposed system would name for decreased forces due to the ensuing easiness in maintaining and keep Parish records and accordingly. the running costs of the parish would significantly cut down. ?Accurate and dependable fiscal records would be kept utilizing the proposed system through the fiscal faculty which would supply security to fiscal inside informations and merely let entree merely by authorised persons. This would advance some degree of transparence and answerability in the handling of Parish fundss compared to the bing manual system which can be easy tampered with. For case. with the manual system paperss reflecting fiscal inside informations of the Parish can be distorted by H2O or plagues. Malicious persons can take advantage of such a state of affairs to perpetrate fraud. ?With the proposed system. departmental direction is easy. All Parish sections and the activities that revolve around the sections are good recorded and updated consequently. Groups in the Parish are every bit good better managed through the propose Integrated Parish Management solution. This is unlike the old system where a director or Parish caput has to physically interact with departmental caputs to acquire the needed information.

Definition of Compassion Essays - Emotions, Giving, Compassion

Definition of Compassion Essays - Emotions, Giving, Compassion Definition of Compassion The author Barbara Lazear Ascher breaks down the definition of compassion whether if its something that a person will exhibit when confronted by dangerous situation. For example, when a beggar walks into a bakery or a food store, the store owner immediately gives that beggar some food because she fears that man may ruin the stores image or may scare customers away. She questions in present day, this scene gets replicated in so many different parts of the country. It makes us ask: Is this compassion or fear? The answer according to the author is fear. People are difficult to show compassion spontaneously. Some of them do have genuine compassion, but by and large, no compassion. Ascher begins her passage by describing a scene that most readers can relate to: the womans interaction with the homeless man on the street. Generally there are some senses of fear when in the presence of a man who know nothing about, and cannot expect anything from him at any given moment. This man stares at the children; then the mother instinctively protects her child, he stops before a blond baby in an Aprica stroller. The babys mother waits for the light to change and her hands close tighter on the strollers handle as she sees the man approach. With these words, we find the author conveying a sense of fear through revealing her actions. Whereas the child also instinctively shows his fear by his action, The baby, weary of the unwavering stare, pulls its blanket over its head. The author shows that a child has no inhibitions and is not afraid to show his fear, whereas the mother masks this fear through compassion. His eyes fix on the baby She finds what shes looking for and passes a folded dollar over her childs head to the man who stand and stares. Yet we find that the man is unaware to the nature of this reaction. His hands continue at his sides. He does not know his part. He does not know that the acceptance of the gift and gratitude are what makes this transaction complete. Therefore she continues on her way, Bearing the dollar like a cross. When people find someone bearing a cross generally, or making reference to God, its a sign of desperation or some form of protection. Thus it can be implied that the woman bears the dollar as a manner to protect herself. Now the man has not take that dollar; it could be said that this dollar symbolizes the idea of falsity that generally one may bear the cross, but may not believe in it; just as she may give money, but it is not compassionate. Another example that Ascher offers to dissect the fear of people is a man walking into a coffee shop. The owner of the shop, a moody French woman, emerges from the kitchen with steaming coffee in a Styroloam cup, and a small paper bag of of what? The man grabs his things and is off. The owner of the coffee shop is described as moody that bringing the question of kindness to light. The reason that owner does this is she is afraid of the homeless. As he stands, the scent of stale cigarettes and urine fills the small, overheated room. The man makes the atmosphere of the cafe become badly as he walking inside. She thinks he may ruin her stores image or may scare customers away, and its not good for her business. In my opinion, Aschers describing of these men causes a strong influence on me. The homeless man originally walks in silently. If he barges into the cafe and demands or asks for food, I will think of him as rude and lazy, and the owner kicks him out will be accepted. And Ascher d oes the same to the bagger. If the bagger is white, race will not be an issue. It will be clearer that the woman offer money in pity rather than fear. Also, if the man dashes for the money, I will not receive the image that he is kind and gentle, but that he is aggressive and can cause harm. Ascher describes these men as

Xiaotingia - Facts and Figures

Xiaotingia - Facts and Figures Name: Xiaotingia; pronounced zhow-TIN-gee-ah Habitat: Woodlands of Asia Historical Period: Late Jurassic (155 million years ago) Size and Weight: About two feet long and five pounds Diet: Insects Distinguishing Characteristics: Small size; long tail; primitive feathers About Xiaotingia In order to understand the importance of Xiaotingia, you need a short lesson about a much more famous animal, Archaeopteryx. When the exquisitely preserved fossils of Archaeopteryx were discovered in Germanys Solnhofen fossil beds in the mid-19th century, naturalists identified this flying, feathered creature as the first true bird, the key missing link in avian evolution. Thats the image that has persisted ever since in the popular imagination, even though better-informed paleontologists now know that Archaeopteryx possessed a weird mix of bird-like and dinosaur-like characteristics, and probably should have been classified as a feathered dinosaur (rather than a primitive bird) all along. So what does all of this have to do with Xiaotingia? Well, this very Archaeopteryx-like critter, discovered in Chinas Liaoning fossil beds, predated its more prominent cousin by five million years, living about 155 rather than 150 million years ago. More important, the research team that examined Xiaotingia identified it right off the bat as a small maniraptoran theropod that shared important features in common with raptor dinosaurs like Microraptor and Velociraptor, rather than a prehistoric birdthe implication being that if Xiaotingia wasnt a true bird, then neither was Archaeopteryx, which was only recently descended from it. This has caused a large amount of consternation in the Archaeopteryx was a bird camp, but hasnt impressed those more dubious paleontologists who doubted Archaeopteryxs credentials in the first place!

Microbio - Essay Example 84). It displays immunological memory through which it recalls having encountered an invading organism thus reacting more rapidly on the same organism on subsequent exposure. This paper is a discussion that compares and contrasts the innate and the acquired immune responses. When a person comes into contact with an infectious agent, the first defenses to counter the infection are physical, as well as, chemical barriers like; antimicrobial proteins that are secreted at mucosal surfaces, which deny the microbes from getting into the body. In the case that these barriers are overwhelmed, or dodged, other immune system components get into action. The complement system is able to recognize the foreign organisms, as well as, phagocytic white blood cells like the innate immune system macrophages and neutrophils, and destroy them immediately (Minnicozzi 115) In contrast, the acquired immune response, also referred to as the adaptive immune system, develops in days. It is, however, able to el iminate infections in a more efficient way due to the lymphocytes exquisitely recognition functions that are specific. These cells are able to respond to every antigen through antigen receptors that are highly specialized which are present on the lymphocytes surface. The lymphocytes present in the body in their billions, possess a vast range of antigen receptors collectively, which make it possible for the immune system to identify, and take action to virtually any antigen an individual may be exposed to. This enables the adaptive immunity to focus on overcoming the pathogens that have eluded or overcome the innate immunity. Additionally, the innate immunity defense systems are effective in battling many pathogens. However, they are constrained by their reliance on germline-encoded receptors in order for them to identify microorganisms that have the ability to evolve more rapidly than the infected host. This is why they are able to only identify microorganisms that bear surface mole cules, which are common to most pathogens conserved over the evolution course. Most pathogenic bacteria contain a protective capsule that has evolved that makes it possible for them to hide these molecules making it difficult for them to be recognized and phagocytosed. Viruses do not carry invariant molecules like those of bacteria, and the macrophages rarely recognizes them. However, viruses, as well as, encapsulated bacteria may nevertheless be picked by dendritic cells via the macropinocytosis nonreceptor-dependent process. This may then reveal the molecules that mask their infectious nature activating the dendritic cell to present the antigens that belong to them to lymphocytes. (Kobayashi et al. 5123). All the blood cellular elements such as the red blood cells which transport oxygen, platelets for triggering blood clot in tissues that are damaged, and the immune system white blood cells, originate from the bone marrow’s hematopoietic stem cells. Since these stem cells h ave the ability to produce every different blood cell types, they are mainly referred to as pluripotent hematopoietic stem cells. They give rise to additional limited developmental potential that are the instant progenitors of platelets, red blood cells, and the two major

A change would be done through an amendment that would have to be proposed by a majority from both sides of the legislature, and the amendment would have to be adopted by the voters. The second method suggested a modification based on a revision that would have to be adopted in a constitutional convention. The same arrangement would hold with slight modifications in 1879 where a legislative proposal would have to be approved by a two-thirds majority of both houses rather than a simple majority. The approaches featured shed some light on the factors that would have to matter in the wake of a need to modify the constitution in the face of possible implications on the rights of others. Lack of early similar cases that would otherwise offer insight on the best direction to follow is underscored.However, Supreme Court’s decision in 1894 insisted that the legislature reserved no power to propose revisions, an element that is distinguished from amendments. This would hold until 1911 when the Progressives had an initiative in place that would see the electors have the power to propose statutes and amendments to the constitution with the ability to adopt or reject them. This would allow California to bypass the demands posed by the legislative proposal and would use initiatives directly to pose amendments to the constitution. Another turn in 1970 would give power to the legislature to propose amendments and revisions by two-thirds in both houses. This means an amendment can be done by having a measure placed upon a ballot, an action that can be facilitated through a legislative proposal or a

Field Research - Essay Example There is no denying the fact that a majority of the top models were affiliated to a few select brands like HTC, Samsung, Apple, Nokia and Blackberry. The Smartphone available at this store evinced a range of features and applications. The Samsung Galaxy S4 happened to be a really top end phone that offered varied flexible possibilities like the option to use microSD to expand the phone memory. This model was virtually an Android powerhouse. The phone came with an eye tracking and Smart Scroll feature that allows scrolling while looking at the screen while keeping the phone a little tilted. There is a smart pause features that pauses the video being played if the user is not looking at the screen. The Air View feature allows implementing advanced functionality by holding or swiping a finger or a hand slightly over the phone. Group Play feature allows for an ad hoc sharing of files between Galaxy phones as is the case in multiplayer games and also facilitates music streaming specifical ly in Galaxy S4 phones. Truly speaking this phone came with a range of advanced features. Apple iPhone 5 also happened to be a top class phone that promised multiple advanced features. ... With its advanced wireless technology, Apple iPhone 5 connects to more networks around the world. The speed is remarkable that allows for a hassle free browsing, streaming and sharing. The phone comes with the new A6 chip that is very powerful, without taxing the battery anymore. HTC One happened to be a Smartphone that came with a range of features not available in other Smartphone. It came with a 4MP UltraPixel Camera that happened to be the best in its class. HTC One runs on Android 4.1 (jellybean) however its user interface is way apart from the regular Android user interfaces. This model has done away with the standard Android hardware button layout and the device could be readily navigated with the help of only two keys. The BlinkFeed feature is really unique as it indeed boosts content sharing, and social media integration. The phone comes with two powerful frontal speakers. The phone comes equipped with an infrared based blaster that allows it to act as an extension to the us ers’ TV. The price of the Smartphone available at this retail outlet varied from as low as $97 for the Blackberry Bold 9650 (without contract) to as high as $605 for Galaxy S4 (without contract). No wonder the price variation in the market for Smartphone is high and a consumer really gets confused as to the brand one can chose. The special thing that was noticed in case of most of the Smartphone models was that packaging and display evinced a hallmark of marketing astuteness. In most of the models the packaging happened to be sleek and was mostly intended to enhance the aesthetic appeal and to allow for easy display and stacking in the stores. In terms of the packaging, most of the brands made it a point to appear innovative and unique. In the Smartphone market there

Change Management College - Essay Example (Cummings. Worley: 1993). Organizational development and change management are concurrent fields which have a common basis and aim that of overall progress of the organization. However each field has specific nuances which are being discussed herein. (Davis: 1998). The aim of change management is to enhance organizational competitiveness. This can be achieved by strategic change and congruence in various facets of an organization, such as aligning the people, processes structures and culture. Change management is designed to change behavior before attitudes. (Davis: 1998). It is commonly believed that a large number of projects fail to achieve the expectations of the senior management. (Responding to Change). A survey by PricewaterhouseCoopers (PwC) and MORI carried out in the late 1990's revealed that 9 out of 10 barriers to change were related to people and included lack of change management skills, ineffective communications and resistance by employees. (Responding to Change). The phenomenon of organizational change is complex as it involves a number of inter related factors to include the stake holders, the people and the technologies. The key factors in change management are what are known as the softer issues of transforming behavior and training of the staff to accept change. (Responding to Change). ... Two models of change popularly known as the Lewin Model and the Bullock model are being examined herein. Lewin Model of Change - Salient Features Kurt Lewin's model of change evolves from the social-psychological approach to change management which had its matrix in Lewin's observations in the area of field theory, action science, group dynamics and organizational development. The main theme of the model is that an individual is shaped by the social environment rather than his genes. Thus the model entails three steps of unfreezing from the present state, moving to the new state and refreezing in the new state. The first state involves creating dissatisfaction, while the second stage involves organizing and mobilizing resources for change and the final stage, embedding the transformation in the organization. (Change Management : 2006). Thus a transformation from an existing quasi equilibrium to a new quasi equilibrium takes place as indicated in Figure 1. Figure 1 Transition and Forces of Change State A as seen in Figure 1 depicts the status quo of a social system which is held by two sets of forces which are shown by the arrows, that of change and status quo, which results in constancy at L2. In State B change is achieved by increasing forces for change and decreasing resistance thereby accomplishing change through high tension. While State C which takes up limited energy is as proposed by Lewin, wherein the resisting forces are reduced by a number of initiatives which consumes lesser energy than that required to expand the forces of change. (Schumacher). Thus learning is the primary mode of bringing about behavioral changes in people which is undertaken by increasing knowledge and broadening horizons of people affected,

Collaborative Innovation. Things that motivate companies to Essay

Collaborative Innovation. Things that motivate companies to collaborate in innovation - Essay Example Technology increases the productivity and profitability of a firm in which it is used. Usually, firms collaborate to innovate in the running of their businesses (Gloor, 2006, p72). When two or more firms choose to work together to develop a technology, they identify the things they have in common. Various factors that are perceived to be beneficial to partnering firms cause them to come together and innovate together. Some of the factors that cause firms to collaborate in innovation include reducing the cost of development of the technology, reducing the potential risks that are involved in technological development or entering the market, to achieve the economies of scale, which reduce the cost of production, promoting shared learning between the firms involved, and reducing the time taken to produce and market new products (Tidd, Bessant and Pavitt, 2005, p25-78). The results of the collaborative invention vary significantly according to different companies, and these factors may b e beyond or within the abilities of the partnering firms. Some factors that influence the results of a collaborative interaction between firms include: the competitiveness of the partners, the transparency issues, receptivity of ideas, the rate of learning and bargaining power of partners, the intention of the firms when they accepted to enter into collaboration, and sustainability of the deal (Hamel, 1991, p.83-101). These factors determine whether or not the collaboration will continue in order to develop technologies together; if the factors are favourable to the collaborating firms, they continue to develop technologies together. Different companies collaborate in innovation according to different interaction policies. These interactions are determined by conditions that are set by those partners, when joining together as well as those that are related to sustainability. In order to understand the issues that are related to the collaborative innovation, there is need to explore the factors that influence firms to come together as well as those that influence the sustainability of collaborative innovation interactions. Things that motivate companies to collaborate in innovation In events where firms collaborate to innovate, they need to put into consideration all the issues that can arise from it. When firms focus narrowly at the reduction of cost, it may work not for their benefit because although collaboration may reduce the cost of production and enhance economies of scale, it is also possible that the company will need to establish a strategy of developing the collaborative relationship. For instance, if firms consider the factor of cost reduction in a collaborative innovation deal, they can evaluate other costs apart from the basic raw materials for the company. A good collaborative innovation deal needs to consider the amount of money that will be required to facilitate collaborative capabilities. For instance, different firms will need to develop peo ple within their firm that will sustain the technology that they develop. This means that they should not develop a technology that they will lose within a short time (MacCormack, Forbath, Brooks & Kalaher, 2007, p17-102). Firms may be driven to form a collaborative interaction in innovation by their need to increase the income share; this is by maximisation of all the opportunities they have in their production. Every chance a firm has to reduce the risk of making losses and increase profitability becomes a motivation for the company to involve other companies to innovate (Da Vinci, n.d, p1). When firms come into collaboration, they intend to develop fast to gain their competitive advantages.

An analyzed look into current botnet controls Thesis Proposal

An analyzed look into current botnet controls - Thesis Proposal Example Practically speaking one botnet could be made up of ten thousand machines.It is quite difficult to identify since they are vigorous in nature. This is in order to escape the security measures put in place. This is done through the download ofsoftware called a â€Å"bot† for example AgoBot. The download comes along with afixed payload incurred by an un-suspecting user. This download is executed through the clicking of email attachments that have been infected ordownloading infected files from malicious websites. The bot software can also be transmitted as freeway in peer to peer networks. After the installation of the bot with the fixed payload in the computer, the machine makes contact with a public server set up by the botmaster. This server is the control panel that is used to give commands to the botnet. A popular procedure involves using public (IRC) Internet Relay Chat servers. The control panels are frequently changed to avoid being detected. They are managed by machines and proxies that are not owned by the botmaster. The botmaster uses the control panel to send new exploit-code to the bots or to modify the bot-code so as to avoid detection through signature methods. This code is also used to insert new commands and attack victims (Patrick Lee, 2009). The botmaster’s main objective is to enlist new nodes into the botnet. A node is any computer that is connected to the internet hence making it a target for attack. Each node is commanded to search for other potential hosts. This pattern follows for every other machine that is recruited into the botnet. Therefore the machines that were in the botnet before and the new continuously carry out the search. Within a few hours, a botnet can become very large with a composition of millions of PCs on different network throughout the world. Given the large number of zombies distributed

Lil Wayne vs World Essay Example for Free

Lil Wayne vs World Essay During a CBS interview with rapper Lil Wayne, Katie Couric asks What does that mean, when you say Im a gangster? Wayne replied, â€Å"I dont take nothin from no one. I do what I wanna do, And Im gonna do that until the day I die. And if I cant do that, then Ill just die(All Access). Katie Couric and Lil Wayne sat down together on national television for an interview where two people of vastly different backgrounds had a conversation. Kwame Anthony Appiah, a professor in top Universities across the world, describes a conversation to be engagement with the experience and ideas of others. Also, the more dissimilar the backgrounds are the more information can be exchanged between two people. â€Å"America’s Sweetheart† Katie Couric and ‘Weezy’ (Lil Wayne) are undeniably two very different people. Seemingly their only similarity is their fame. Although as their interview progresses one can see how they are able to connect and exchange their own cultures with one another. The famous Lil Wayne is far from average, making this and all of his exchanges other extremely valuable to cosmopolitanism exposing his miscellany to the masses. By the end of the interview, although not necessarily in agreement, they both seem to have an understanding of one another accomplishing the main goal of conversation. Any person who is somewhat familiar with hip-hop should know who Lil Wayne is. 28-year-old Lil Wayne is loved by millions of teenagers for his music with his recent album The Carter III being the highest selling album in 2009. By default Lil Wayne is a role model, anyone with his amount of fame and recognition is going to have influence on others. What makes Lil Wayne a unique role model is that he is not the standard ‘liked by all’ leader that most mothers would approve of. Rapper Lil Wayne has been arrested for possession of drugs and illegal weapons three times with the third putting him in jail. A majority of his raps consist of drugs, money, and sex. Is this a role model teenage fans should follow? These aren’t typical traits that one would normally see in a role model but his unconformity is what defines him and makes him the icon he is. In countless interviews and talk shows Lil Wayne is asked about his notorious drug abuse. He gives the same response each time showing no shame, I will stand up for marijuana any day Im a rapper. That’s who I am†¦ I am a gangster and I do what I want. And I love to smoke. And I smoke(all access). In his mind what he does is not wrong and as Kwame Anthony Appiah understands, â€Å"A good deal of what we intuitively take to be right, we take to be right just because it is what we are used to.† Who can say that what Lil Wayne does is wrong? Right and wrong at the most basic level is man made. What he believes is right is what makes him happy, and it is only because we are used to marijuana being illegal or we are used to frowning upon his life style that it is considered â€Å"wrong.† For someone who does a lot of ‘wrongs,’ he is overwhelmingly successful. Lil Wayne has a net worth of 75 million dollars, â€Å"Following the drop of his sixth studio album Tha Carter III in 2008 he was nominated for eight Grammy’s, the most for any artist that year taking home four awards. Wayne†¦ was named #2 on MTV’s list of hottest MC’s in the game behind Brooklyn bred rapper Jay-Z† (Celebnetworth). Lil Wayne is only 28 years old yet h as more success than most can ever dream of obtaining. â€Å"Some call him the best rapper to ever live others say he’s self-destructive but whatever you believe Lil Wayne has become a staple in American music and will remain there, indefinitely†(Celebnetworth). People aren’t used to a successful â€Å"gangster† like Lil Wayne coming from nothing and breaking the law while reaching the top. Lil Wayne embraces his vice-filled lifestyle, and thrives off of it. Like his hit song ‘I’m me’ expresses â€Å"Baby, Im me, so who you? Youre not me, youre not me.†(metrolyrics) He knows he is one of a kind and he knows he is the best. This is the attitude that attracts so many of his fans. His confidence and arrogance is what really defines him and his success just adds to his ego. While arrogance is not usually good, he gives off a confidence that many people can learn from when engaging in any of his conversations. At first look he may not appear to be very intelligent, but what many people do not realize is that Lil Wayne received straight A’s while in school. For me, it was always a way of showing someone my intelligence, a way of showing someone who I really am, Wayne says about his music(all access). When listening to Lil Wayne converse with Katie Couric, he is actually a very articulate speaker. Even through his lyrics one can see how descriptively he express his mind. Even the way he creates his rhymes is impressive. Lil Wayne never writes lyrics down before he records his songs. Every time he records a new song he raps impromptu, putting together rhymes as he goes. The ability to think that quickly and produce coherent thoughts unrehearsed in the form of music is astounding. The majority of people I’m sure do not know this about Lil Wayne and would never think of him as genuinely very intelligent. His intelligence confuses most people who immediately profile this black thuggish rapper as brainless. As Appiah understands â€Å"Understanding one another may be hard†(25). To fully understand Lil Wayne or any person is not easy, and those hidden characteristic of people, such as Lil Wayne’s genius, is what conversation can unveil. The complexity of this 28-year-old rapper allows for extremely beneficial conversation, changing first impressions and providing new perceptions. Lil Wayne uses music to reach the world exposing his intelligence and talent to millions. I believe that music is another form of news, he tells CBS News anchor Katie Couric. Music is another form of journalism to me so I have to cover all the areas with my album(allaccess). In many of his songs Lil Wayne will address current events. Katrina was a very sensitive subject to many and Lil Wayne having grown up there and lost ones who were close to him as shown in his lyrics. â€Å"To those restin in peace, those dead and deceased, soon again we meet†(metrolyrics). Lil Wayne donated $200,000 To Hurricane Katrina Relief Project to help the area where he grew up(Gigwise). Through the medium of his music he expresses his feelings, and has a vast amount of influence. This is what Appiah believes is necessary; to influence others and exchange ones own ideas like little Wayne does through his music quoted above. Whether people like it or not Lil Wayne is a leader. There is a reason he is so loved by his fans and has had so much success. He is a success himself and what people all over the globe strive to achieve. Alternatively when examining his habits and way of going about life it is hard see him as a positive influence in any respect. He does illegal drugs, possesses illegal weapons, and is known to be a womanizer in many of his lyrics. Recently he was arrested for possession of weapons without a permit. To many teens this looks â€Å"cool† and just adds to his notoriety. Illegal activity isn’t the key to success for most people, yet as he proclaimed, he is a gangster and can do what he wants when he wants. This cocky attitude gets him in a lot of trouble, but it also fuels his greatness. With every hero there is a flaw and Lil Wayne’s flaw is breaking the law. Most of his followers understand that some of his actions we should follow; instead following his confidence and individualism that yield success in an increasin gly competitive world. During the CBS interview Katie Couric asked if he views himself as a positive role model, Lil Wayne replied, I’m not an example for how people should live their lives, Never in my life would I ever set out to be an example for people on how to live their lives. If you need an example for how to live, then you just shouldn’t have been born.† Practicing what he preaches Lil Wayne does not live for anyone but himself. It is this attitude that intrigues people and causes conversation. Every time he makes a new song that tops the billboard charts he is reaching out and sharing himself with the world. Lil Wayne has conversation everyday when he makes his music, sharing himself with many different types of people each with their own varying backgrounds. Appiah would agree that Lil Wayne is someone people of differing cultures can learn from being as unique as he is. His uniqueness allows for good conversation by crossing boundaries like done in the CBS interview with Katie Couric, while still being able to connect easily with society as shown through his fame. Lil Wayne has always been himself and while many times misunderstood he will keep being Weezy F Baby, â€Å"The Best Rapper Alive.†

Network Troubleshooting Symptoms And Solutions

Network Troubleshooting Symptoms And Solutions Data transfer from one point to another is the most important aspect of computers. Networks should be safe, reliable and secure for data movement. Any problem which occurs with computer networks causes havoc. Understanding networks, the way they work, and how they are built helps a network administrator to identify and fix the problems. 11.2 Procedure to troubleshoot network problems A simple formula that enables network administrators solve any kind of network problem is: Identify the symptoms. Identify the affected area. Determine what has changed Select the most probable cause Implement a solution Test the result Recognise the potential effects of the solution Document the solution 11,2,1 Identify Symptoms Indicators are either physical or logical symptoms that help determine the nature of the problem, the reach of the problem, etc. These symptoms enable a network administrator to take timely preventive measures to solve the problem before it grows beyond control. System or operator problems System errors arise from a computer, network device or a process that is not related to a users direct interaction with the system or network. Such errors can occur due to hardware failure, faults in the process of data transfer or manipulation. Operator errors are a direct consequence of a users action. The actions that can cause such errors may be incorrect log in, wrong connections to a server, misidentification of servers or network devices, incomplete network connections, etc. Mistakes on part of the network administrator that are common causes of operator errors are misconfiguration of devices, programs or services. Link lights When a networking device detects a network connection a green or amber Light-Emitting Diode (LED) is turned ON. This is the link light that shines when in the ON state. Components of a network are designed with link lights to show the state of the network connection. When a physical network connection is present a link light remains on and another light is present that displays the current activity of the network card and blinks, pluses, during data transfer.. Link lights are designed to not light up in case of an incorrect network cable connection. By examining the link light of a device, a user can determine if a network connection is running or not. Collision lights Lights that indicate whether a certain connection is facing problems due to packets colliding with one another is a collision light. The collision light (activity light) is green while sending and receiving data and is yellow or orange when a collision error is detected. The packet being received or sent is lost when a collision occurs. Faulty cables or hubs can result in packets being generated from other packets or electrical interfaces which when in large magnitude are called chatter. These network chatters can end up halting an entire network because of data packet collision. Network administrators and users should monitor these lights to detect network chatter and avoid it. Power lights A power light indicates if there is power supply to the networking device or not. In case there is no power supply the power light is off. The power supply cables or wall connectors should be checked for proper connections while troubleshooting a network problem. Error displays A device failure or malfunction is indicated by an error display. A visual error dialogue box on the computer or an LED error display on the network device is the form of an error display. These displays also describe the problem that is detected. Typically, an error display relates to an error code that should be referred by the user to identify the cause and a suitable solution. Every physical or logical problem has a unique solution provided by its manufacturer which can be found in its documentation. Error logs and displays A list of the errors encountered on a network device is the error log. The time of the error occurrence, the nature of the error and a suitable solution is what constitutes an error log. The information found in an error log is not sufficient to solve a problem and requires the support of the related documentation to resolve the problem. Error logs are important sources of information that includes the time of the error, probable cause and other processes affected by the error. An error display gives a visual alert of a problem and logs it in the error log. Not all error displays require immediate attention but a few are warnings that do not indicate an existing error but need attention. An Event Viewer is an error logging mechanism which is typical to Windows-based OS such as Windows clients and servers. Event viewer is a critical tool in diagnosing and resolving a problem. Red-X error entries that have occurred are recorded in an event viewer. This is an application that reads the binary log files stored at system32config folder. To view the error logs, the network administrator requires to view the config folder because the event viewer collects information from the files located in that folder. Error logs are of three types which should be monitored by the network administrator regularly and they are as follows:. System log Error messages that are related to device driver failure, service start failure and general information about OS events are recorded in the system log. Security log When auditing has been enabled all security related events are recorded in a security log. Application log Events that are generated by application running on top of the OS are recorded in an application log. Identify network problems Troubleshooting a network is one of the key concept in networking. Identifying network problems and determining methods of troubleshooting these problems is vitally important for smooth functioning of a network. The job of highlighting the problem is usually done by the network user. This should not be the basis on which an administrator should attack a problem. It is advisable to experience the problem in person along with the user who reported it. This helps the network administrator confirm if the problem is real or just an error. There are certain users whose knowledge about computers and networks is not vast. With such users when a problem is reported, a first-hand inspection and confirmation are necessary. The best approach to solving a problem is by determining its scope. The reason why an understanding of the nature of the problem is essential is that it determines the line of attack. Gathering information helps the network administrator to narrow down to the root of the problem. This approach avoids a network administrator spending unnecessary time on unnecessary jobs. After the network administrator is able to pinpoint the cause of the problem, then finding a solution is possible. A network administrator must first gather information to find out if the problem is with a single computer or with the entire network. In case the problem is local, then the entire network is not burdened and a solution can be found easily. The first logical step that is to be taken is to check all cable connections to and from the system. It is not advisable to look into bigger issues or target larger sources when the cause might be very simple. The reason why a system is not able to connect to other systems may be that the network cable is not plugged in properly into the system. When the cable is connected properly, the network connection is up and running. For example, if two systems in a network are not able to communicate with each other then the network administrator can perform simple checks like verifying the connections between the systems or connections to the network A network administrator should check if a problem is consistent and replicable. If the problem reported unique to a system or can it be replicated in other systems in the network. If the same problem is reported from another system also, then the problem is consistent and replicable. The degree of damage is high in such a case since many systems are affected. If the problem is identified to be with the network, then the network administrator must reach to the cause of the problem step-by-step. A large computer network requires a lot of effort from the network administrators and users for it to run smoothly. Adding to the huge task of maintenance is the job of fixing a problem. It becomes difficult to identify the actual problem for there are numerous workgroups and workstations. It is advisable to approach large network problems with the trial and error method. The administrator should first check the local system from where a problem has been reported. A thorough check of its cable connections, network links, power supplies and so on should be done. If the problem is not with a local system then other systems in the vicinity should be checked. The routers to and from the system should be verified for proper functioning. The various connections should be verified. One of the best methods to check and fix network problems is to try connecting to other systems and parts of the network by pinging to them. 11.2.2 Identify the affected area. After the cause of the problem is identified it is simple logic to isolate the affected area. This step helps an administrator narrow down to the core of the problem. With many issues to be handled at a time; administrators must prioritise the problems. Issues which affect work to a large extent should be fixed first and the rest should follow sequentially. By doing this the downtime can be reduced and the system can be fixed faster. Same line, different computer While trying to solve a problem it is important to isolate the affected system. A simple method of testing if the problem is replicable is by replacing the original workstation with another system which is known to have no problems. By confirming if the problem is with the local system or beyond it, the network administrator eliminates one factor of the problem. An easy way of isolating the system is by replacing it with another system. This step determines if a problem is computer specific or not. Same computer, different line When a user reports of a problem, another method by which the administrator can reach the cause of the problem is by changing the network cables for the system. By doing this, the possibility of a network error can be identified or nullified. In case the system works properly with a new connection, then it is for sure that the problem is with the original network and not the computer. Swapping components In a network, hubs, cables, terminators can be swapped with other systems to check for replication or consistency of a problem. This helps in case there is a faulty component and the work of the original system user is not disturbed since a spare is in place. This step helps determine the scope of the problem and address it appropriately. Prioritising work is very important for network administrators and network administrators since the time and effort used to fix a problem should help users to get back to work faster. Bigger and crucial problems require immediate action while the smaller ones can be addressed after the bigger ones are fixed. Isolating segments of the network By isolating parts of the network spread of the problem is checked such that the entire network does not collapse. The systems which have reported issues are required to be disconnected from the network and terminators plugged in. This is a safe practice as it helps the network administrators fix the problem with lesser overloads of data and work. Steps for problem isolation are given in Table 11.1 Step Action Determine which systems are and which are not showing symptoms. Separate the systems that are showing symptoms from those that are not with hubs or terminators. Rule out simple issues. Reset all major connections to and from the system. Eliminate cable problems. Check for physical damage or erroneous connections of cables. Eliminate serious cable issues. Use TDR to find out cable problems. Table 11.1 Methods to isolate network problems. 11.2.3 Determine what has changed Computer networks have many components, both hardware and software that can be replaced or reset to meet the requirements of the business. This can also be one of the causes of a network problem. For example, if a user reports of a problem after a system in a network is replaced then the administrator should check if the address of the changed system is properly recorded and connected with the existing network. To be able to fix problems when changes are made to the network, it is advisable to maintain proper records of all details about the new and existing network such as the points of change, the components of change, their versions, IP addresses and network cables. A detailed documentation system helps fix such issues quickly. Checking the status of servers Servers are an integral and crucial resource in a network. Their health is very important for functioning of a network. Therefore it is logical to check the server status when faced with a problem. If sever issues are not addresses on time, then the degree of damage can be high. A few server monitoring tasks that can monitor their status are as follows: Check services Check error logs Check connectivity Monitor performance and network traffic Confirm alerts and alarms Verify backup logs along with test restores. Checking error logs Error logs are an important source of information for a network administrator. It throws light on the errors that have occurred and their nature. The amount of damage can also be assessed from this log. The administrator can prioritise errors on the extent of damage and fix them in that order. It is important to review the error log on a daily basis because certain errors have dependencies which can spread the damage faster. It is advisable to make it a habit to check the error logs at some point of time in the day to help the network work better. Connectivity between systems or servers can be tested using the Ping feature. If the system at the other end of the ping message responds then the connection is intact, else a thorough check of the connection should be done. Regular checks should be carried out to look out for server overload problems. An overloaded server can slow down system performance and speed. Backup servers should also be monitored for updates and performance. In the event of an emergency backup data and resources are very crucial. An alert system can be designed which can raise alarms when predefined limits are exceeded. This is a good preventive measure that helps in proper functioning of a network. Checking for configuration problems Before introducing a new resource into the network it is necessary to verify the existing configurations and connections. In case the existing settings are incorrect, then the new resource cannot work. For example, before setting up a new server it is good to check the base OS, TCP/IP, network cables, error logs and memory allocation for accuracy. This improves performance and does not allow deterioration of the system. After the existing settings and connections are verified the new resource and additional services must be configured accurately. There are a few tasks which require the entire network to be turned off for a few minutes before rebooting. This activity has to be timed for low work load hours. A few critical services which determine functioning of the entire network and requries constant monitor and accurate configuration are: DNS a Microsoft active directory and other Internet-based applications supports this service. A detailed plan should be in place before configuring a DNS which require a list of information before installation. Domain name WINS WINS is a feature similar to DNS which resolves NetBIOS names to IP addresses. This is a dynamic service which can add, modify and delete name registrations and avoid human errors and save time. WINS has many configuration possibilities and the user can add a static mapping for clients or severs. Host file Host files and DNS are similar in function. Host files require manual configuration of database with exact mappings of hostname to IP addresses. Host files reside on every computer making the process of updating difficult. It is very important to provide correct hostname to IP address mappings so that all rules that apply to the DNS, also apply to the host files. To avoid typing errors while configuring host files, it is safe to copy the existing hosts to the newly created file and on each of the machines. Checking for viruses Viruses are a huge and common threat to computers. A computer network is at greater risk as the number of computers is large and the damage can be huge. Protecting networks and computers outside of networks from viruses is a top priority job. Viruses grow in the computer world at a pace which matches the growth in the biological world. The mechanisms to destroy viruses evolve every minute to fight the strongest and newest virus. It is the job of the network administrator to keep the network free of viruses. Constant updates of virus definition files, scans to check for entry of viruses and antivirus software are the most popular and best methods to fight them. Preventive measures are best when deployed round the clock. All resources in a network should be scanned for viruses and guarded from them. Every piece of software and hardware is crucial to the smooth working of a network or system. There are a number of virus scanning utilities available in the market which enables computers to automatically update virus definition files from a core server therefore avoiding the administrator making trips to each workstation. Checking the validity of account name and password Account name and password are the gates that lead the user to a whole world of services, applications and data. Their validity matters a lot for the user to be able to access services, applications or data. Many services use the built-in system account details for success while a few other services require the user to log on to a remote system. This task requires an account name and password that resides in the network account database. To activate certain services or applications, administrative privileges or membership in certain groups is necessary which again requires account name and password. For quite a few system-related tasks, administrative rights are required which allows the user to modify certain settings to suit the need. The worst situation is when a network administrator has configured many applications and services with the administrator account which gets deleted on end of service of the administrator. If all services and applications using the administrator account are disabled and access is denied, then it is very difficult to fix this. Rechecking operator logon procedures Very often users end up facing problems with passwords. Users try to logon to a part of the network for which access is not granted, forget passwords, do not remember the case-sensitive feature of passwords, and so on. Many a times a user tries more than thrice to logon with a certain or different passwords after which the user is locked out. To resolve this minor but deep-penetrating issue the administrator must reset the password for the user. Passwords should be changed at regular intervals for safety and to avoid expiry and this is an issue for many users. Selecting and running appropriate diagnostics Diagnostics is an essential tool to even out variations and eradicate potential problems in a network. Though this is a preventive mechanism the benefits of using it are many. Diagnostics look out for bottlenecks and problematic situations. Diagnostic tools bring out problems or drawbacks and limitations that can be fixed before they erupt as big problems. While choosing a diagnostic program the user should bear in mind the network requirements for which it is to be employed. Smaller networks should use simple diagnostic programs while large networks require extensive protocol analysing and packet sniffing products. Free diagnostic products such as performance monitor and network monitor work well for a medium sized network. To utilise the tool to the maximum without affecting the network performance, the network administrator must research the diagnostic product in depth. With experience and products like these, an administrator is able to identify the problem in time and resolve it effectively. A reliable baseline of activities must be established for testing. Snapshots of different activities at different time periods of the day, week and month helps assess the network efficiently and accurately. 11.2.4 Select the most probable cause Of the many steps suggested to solve a problem, experience of the network administrator is a capability that matters a lot for the process. In case the network administrator is not well versed with the network or common network issues, resolving becomes a tough task. The way a network administrator approaches a problem solves the issue to quite an extent for it can guide or misguide the way the solution is built. In case a new or an outside network administrator is being roped in to solve a network problem the chances of long system downtime is high. The new network administrator has to get familiarised with the network, and then look out for probable causes. The more the experienced the network administrator is, the easier it is to solve the problem. Many a times problems may be similar across systems and a network administrator can tap the experience from the past to fix it faster. A company can benefit largely from a full-time network administrator and who knows the details of the network at the back of the mind. Common problems and their probable causes The common network problems are their probable causes are given in Table 11.2 Problem Probable cause Cannot connect to a computer on a remote network. A routing issue in all probability. Check if it is possible to connect to a local system and ping the router or another system on the remote network. Communication in the entire network is down. If in a coax-based network, check for loose connections. If in a twisted-pair network, check if the hub is operational. If in a token ring network, check if the computer is not beaconing. Takes a very long time to connect to a network resource. Network may be overloaded. A device on the system is not functioning and network connection is not possible. A network card configuration issue in most cases. Check if the NIC is configured properly. Driver may be loaded incorrectly. Communication in a local network is not possible, but other networks are working. Check if the hub/switch is not locked up. Check if the network adapter is configured properly. No Internet access. Check the Internet gateway. Check the router present has a dedicated Internet connection. Check the Internet providers network. Token ring network is locked up. Someone in the network is beaconing. Also check if the bridge is locking up. Table 11.2 Certain problems and probable causes 11.2.5 Implement a solution In order to fix a problem a network administrator can consult others, read related documents, research from the Internet and seek help from the vendor help lines. Finally with a solution on hand that seems most suitable it should be implemented without any delay. 11.2.6 Test the result Confirming if the solution implemented is correct and has solved the problem is very crucial to the problem solving process. Any user contacts the network administrator with a hope of fixing the problem and getting back to work. If the network administrator leaves the user without confirming if the solution provided is correct, then the purpose of the network administrator being present is defeated. It is the duty of the network administrator to ensure that the problem with which the user had approached does not repeat. 11.2.7 Recognise the potential effects of the solution With a working solution in place the next factor that a network administrator should consider is the aftermath of the solution. Many instances can be found where a certain solution to a problem has triggered problems in other parts of the system or network. This cascading effect of a solution requires to be monitored and checked. For example, a user may report a system communication problem and a solution can be provided by resetting of the network cables. The local problem of the system not being able to communicate might be solved, but the system might still not be able to connect to some other parts of the network. Such rippling effects of a solution require attention from the network administrator. Proper implementation of a solution, confirming its working and nullifying all side effects of a solution completes the solution phase. 11.2.8 Documenting the solution After a problem reported has been solved and work is back to normal, it is the job of the network administrator who solved it to document it properly for future use. The fact that certain problems might recur after some period of time, a new network administrator might face a problem already solved earlier, and so on are the reasons why documentation is necessary. An organisation benefits from proper documentation of troubleshooting when there is a change of hands with network administrators, saving on time by not going through the whole process after an apt solution is found by one. It even benefits when a certain solution has faded in the memory of a network administrator. Proper documentation for each aspect of troubleshooting is as good as providing an appropriate solution on time. 11.3 Common connectivity issues in a network The common connectivity issues in a network can be of two types network failure due to physical problems such as device or cable issues and logical problems such as invalid IP addresses or VLAN problems. 11.3.1 Physical issues Cabling problems are the most common physical issues. Visual indicators such as link lights, activity lights and collision lights can be used to fix these problems. A few common problems that a network administrator fixes are: Recognising abnormal physical conditions To be able to recognise deviations from the normal, a good knowledge of what is the normal is essential. If the user is not aware of the default information, then it is not possible to alter or reset details. A user should be aware of certain issues in order to spot a problem. These issues are as follow: Authentication takes more time. More errors are logged than usual. Printing is taking more time. Connecting to a network is getting slower. Connections to resources are being lost. Isolating and correcting problems in the physical media Network cables are the most vulnerable resources in a network. They end up leading to a whole range of problems and can get fixed easily. The cable which is at a high risk of problems is the cable from the workstation to the wall jack. A solution as simple as plugging it back can solve network problems at times. If the problem is not solved, try another cable and try with other cables till contact is established. Cable problem Probable solution Communication in the entire network is down. Check if the cable is intact. The point at which the cable has been damaged should be reconnected with a new cable. The new UTP cable is not enabling network communication. The network is working with the test cable. The new UTP cable might be a crossover cable. Test the connections with a cable tester and replace the UTP cable if not fine. A system was moved to a new location and is not able to communicate now. The system is working properly. Cables might be damaged during transit. Replace the old cables with new ones for proper connection. Table 11.3: Common cable problems and probable solutions. Crosstalk When adjacent wires interfere with a certain wire system it is called crosstalk. The first indication of crosstalk is signal degradation. Using another cable type with multiple layers of shielding is the best solution for this problem. Nearing cross talk Issues in network connectivity occur when a cable wire causes electromagnetic interference in the wires adjacent to it and releases a current. This point has the strongest possibility of cross talk and is generally present in the first part of the wire which is connected to a connector, switch or NIC. Nearing crosstalk helps to measure this type of cross talk. Attenuation Signals degrade as the distance they travel increases, this is called attenuation. If a user finds it difficult to communicate with system at quite a distance, then the maximum cable length for that type of cable would have exceeded. In such a case, a repeater can be used at some point in the cable to reamplify signals or a different cable type can be used. Collisions Data collision is a common issue when there are many systems in a network. Data packets travelling across the network collide with each other affecting network performance. To resolve this issue network hubs can be replaced with switches which has each port on the switch owning its own network segment ensuring that data does not collide. Shorts A network short leads to network downtime. Using a cable analyser to identify shorts can reduce the problem of connectivity and shorts. Open impedance mismatch (echo) Network signals bounce causing communication problems due to high impedance. Signals bounce because of miswired cables or incorrect connectors. Recrimping of the cable is a good solution to avoid high impedance problems. Interference Network cables experience signal interference from external components like power cables, backup lines, etc. Network cables should be laid away from agents that can interfere with its signals. 11.3.2 Logical issues Logical issues have simple solutions but can lead to huge problems if not addressed properly. A few logical issues and solutions are listed in this section. Port speed and duplex settings Confirming that the speed and duplex settings of the network card are set correctly avoids problems for systems connecting to each other across a network. Incorrect VLAN Communication between systems across VLANs is not possible unless there is routing done between them. Therefore placing systems corresponding to the VLAN is important. Incorrect IP address If IP addresses of systems a

Analysis of Human Perception Essay -- essays research papers

When it comes down to our understanding of the world it is ultimately the result of our sensual means of perception. In other terms, can we really trust the truth, or anything that we know of scientifically? What does it mean to know something is true and also why it is important to distinguish between what you know and do not or cannot know? It is very difficult to be able to believe everything you hear, unless you experience it for yourself. Let?s say the perception is like viewing through goggles. If the tint of the goggles is green, the world appears green, if it?s black the world too 'becomes' black. You want to see poverty, you can. You want to see or feel corruption, and you can get that. If you want to see happiness you can see that too. Throughout the thousand of years, people?s opinions of perception have changed dramatically. My definition and opinion of perception is how I distinguish life. What is significant to me, and what do I not care for? My perception was defined by how I was raised in society. I think it is important to have a strong educational background, and have a close relationship with my family, and friends. To other individuals, they may think my perception isn?t correct, they could presume that working hard for money is significant to them, and family or friends is just a minor thing in life. Life is all in the matter of how each individual perceives it. Also it can be different for each person, as mentioned above, depending on his or her lifestyle. It is the substantiality of opinion of what you believe is true. At one point in time, people didn?t require evidence in order to consider something. The world was naive, and di... ..., geographer, astronomer, and astrologer who lived in the Hellenistic culture of Roman Egypt.? (Ptolemy, Encyclopedia) Ptolemy assumed that the earth revolved around everything, and continued to believe this fact, until Eratosthenes proved him wrong. ?He is noted for devising a system of latitude and longitude, and for being the first known to have calculated the circumference of the Earth.? (Eratosthenes, Encyclopedia) All in all, perception has grown an incredible amount. Perception can be taken any way by any person, but my following examples are good ways of looking at how it can only be believed if you have evidence, or how perception has changed dramatically throughout the years. I thought this topic was very interesting to research, and it never dawned on me how I interpreted perception, until I had to write about it.

Effective Classroom Management Essay

According to James H. Stronge in his book â€Å"Qualities of Effective Teachers†, some guiding principles in classroom management are the following: †¢Consistent, proactive discipline is the crux of effective classroom management. †¢Inside the classroom, we could always expect some disciplinary problems, but some teacher could immediately handle the said problems. Instead of formulating immediate medicine for the behavioral problems, the teacher should focus on how to prevent these predicaments to occur. As much as possible, lets avoid dilemmas because it’s too pathetic for us to cry over spilled milk. †¢Establish routines for all daily tasks and needs. †¢To avoid turmoil inside the classroom, the teacher must ascertain routines from the start of the class, up to the class dismissal. This could also help a lot in saving much time and effort because their work is already in routine. †¢Orchestrate smooth transitions and continuity of momentum throughout the day. †¢As much as possible, the teacher must avoid dull moments inside the classroom to motivate the students to always pay attention to the speaker. The teacher must scheme smooth transitions of activities inside and outside the classroom throughout the day. †¢Strike a balance variety and challenge in students’ activities in the classroom. †¢There should be a variation of activities inside the classroom to avoid the students and even the teacher from being bored. †¢As classroom manager, be aware of all actions and activities in the classroom. †¢Even if the teacher is not around, she is still responsible for the students. That is why she must know the things that are happening inside the classroom and what her students are up to. †¢Resolve minor inattention and disruption before they became major disruptions. †¢Disruptions seem to be part in every classroom and in every lesson. No matter how big or small the hitch is, it could still give so much distraction not only to the teacher, but foremost to the students. That is why, if the disruption is still controllable, the teacher must try to stop it before it becomes too late for her to control the situation, and worse, it could spoil the whole transition of the lesson inside the classroom. †¢Reinforce positive behavior. †¢To motivate the students to always do the good and right thing, the teacher should always pay even the simplest compliments in her students’ actions especially to the appreciating ones. †¢Treat minor disturbances calmly. †¢If a simple rising of the voice could control the simple problem, then do it. There’s no need for you to be hysterical and over-react on something that’s just under control. †¢Work out a physical arrangement of chairs that facilitates an interactive teaching-learning process. †¢Some teachers change seating arrangement quarterly. This is to enhance interactions between the teachers and students. †¢Make good use of every instructional moment. Minimize discipline time to maximize instructional time.
