Psychology Of The Internet Essays (1967 words) - Social Psychology

Psychology Of The Internet Summary of the Book Today, the internet is a growing community. Millions of people from all over the world go "online" everyday to check email, research, shop, or even just interact with someone halfway around the world. As this community grows, so does the number of interactions between people. The Psychology of the Internet examines the psychology of new behavior produced by this novel method of human communication. It also delves into the business sector of the internet and how certain companies are using this medium to increase productivity within their companies and corporations. Analysis of the Book The book provides several examples of how the internet can affect the quality of an organization's production. When used in the appropriate manner, the internet can facilitate interaction between a group 24 hours a day and is only limited by the availability of a telephone line. The idea that a person must be in work and at his desk for production is becoming more obsolete as companies realize the potential of the internet. One impressive way the internet can help companies is the workgroups that can be formed internationally. A workgroup is a group of employees striving to achieve the same objective. In the traditional sense, these groups are formed in a room with notepads for each person to help them brainstorm and meetings at regular intervals until the project is complete. The internet revolution is changing all of that. The workgroups are no longer governed by the geographical positioning of its members. I found this particularly interesting because the idea of having a supervisor in Manila, a Research and Development team in Cebu, and a sales group in the United States is becoming more of a feasible possibility than ever before. The internet can also help employees overcome inhibitions that they may not be able to in person. This is due, in part, to the amount of social cues that are lost over a computer. In a chat room, for example, the two employees might know nothing about each other, other than the information they provide about themselves. Therefore, any type of social stereotypes (i.e. sexism, racism, bigotry) is less prevalent than if perceived in the real world. If the employees have never met, social irritations may not be as readily triggered than if in person. For example, if I am irritated by a person who stutters when he speaks, the chances that he will do so over the internet are relatively low. This allows me to concentrate solely on the task at hand and not be distracted by insignificant things. The book speaks of how the internet groups, in the absence of social cues and orders, had to find a group identity online. In other words, the lack of social cues also has its drawbacks. Even if the members of the workgroups concede personal information about themselves, such as their race or ethnicity, the other members might have no physical basis for the connection. So if I wanted to bond with a co-worker who was a Filipino in California, I would more likely do it in person than online. This is due to the lack of human contact and the perception that I am merely interacting with my computer and not a real person. With this in mind, workgroups must find new bases for forming group coherence. The book speaks of the studying of several different multinational workgroups. All were given the same objectives to be completed in a given amount of time. However, only a few of the groups completed the task while only one group did it in the allotted amount of time. The study showed that the groups that failed lacked consistent interaction. After the initial meeting, the members of the group did not log on regularly to converse with the group. Emails were exchanged intermittently among these groups as well. The book states that the main reason these groups failed was that the interaction, already reduced by the lack of human interaction on the computer, was limited to almost nothing. On the other hand, the group that fared the best was noted as having the most email interaction and regular group meetings. The members of the group also took it upon themselves to go beyond what was asked of them simply because they felt a great responsibility to the group as a whole. What caused this desire and cohesion within the group? According to the book, the group kept their personal lives out of the online chatting. Therefore, the members

When Most is Enough

When Most is Enough When Most is Enough When Most is Enough By Maeve Maddox It must be one of those in your face gestures of defiance. It cant be that they dont know better. Im referring to the way so many bloggers create headlines that place a most in front of an adjective that already has the superlative -est suffix: The internets Most Rudest and Obnoxious people Mumbai, India is the MOST RUDEST city in the world The Seven Most Awesomest Idol Moments This Season A Gawker Guide to the Most Awesomest Election Ever Sometimes least is used instead of most in order to compare in the opposite direction: 100 Least Awesomest Things ever Then there are the online novels: at that very moment the most awfullest, most terriblest, most unpleasantest thing imaginable happened! Such pervasive examples of incorrect usage cant be much help to readers for whom English is not the first language. English adjectives form their comparative/superlative forms in one of two ways: 1. by adding the suffixes -er and -est: dark/darker/darkest; simple/simpler/simplest; mean/meaner/meanest 2. by using the words more and most in front of the basic adjective: pleasant/more pleasant/most pleasant awesome/more awesome/most awesome I wont go into the various rules based on number of syllables and stressed or unstressed vowels. Its probably enough to know that adjectives that are short and/or easy to say, form their comparatives with -er and -est. Polysyllabic adjectives that sound clumsy with those endings form their comparatives with more and most. Sometimes the choice is a matter of individual preference. For example, one speaker may prefer handsome/more handsome/most handsome while another likes the sound of handsome/handsomer/handsomest. When in doubt, go with the more/most construction. Most awesomest is not an option for the writer who desires to write standard English. Want to improve your English in five minutes a day?

12 Angry Men

The theme may be a life lesson that was discovered by one of the characters or it may be an evaluation that the author offers regarding an aspect of existence; in other words, a theme is a profound observation about people in general or the way the world works. Theme is primarily shown by the resolution of a conflict. Whether the conflict is between opposing forces (character vs. character, character vs. society) or is within the characters themselves (internal struggle), how a problem is solved and how the characters react sends a powerful message. As we know, the events surrounding the trial of Tom Robinson in the Pulitzer Prize winning novel To Kill a Mockingbird reveal much about the character of people. Similarly, the 1957 classic movie (adapted from the play 12 Angry Men) uses a trial to explore human nature, revealing many important themes. Because both texts explore similar issues of justice (racism, social class, etc. ), they share many of the same themes, including the 12 listed below. 1. Prejudice obstructs the truth (and justice). . True understanding requires time, study, and effort. 3. Intuition can be deceptive neither dismiss initial judgments, nor trust them blindly. 4. There are many interpretations of the facts; few things are truly black or white. 5. Patient silence and loud persistence can both be powerful, at the right times. 6. One determined individual can wield great influence. 7. Courage â€Å"†¦is when you know you’re licked before you begin but you begin anyway and you see it through no matter what. † 8. Respect and understanding are the keys to peaceful coexistence. 9. Real leadership is not derived from titles, but from leading by example. 10. â€Å"You can never really understand a person until you consider things from his point of view—until you climb into his skin and walk around in it. † A person must examine and respect who people are and where they come from if he is to truly understand them. 11. A person is often not what he or she seems to be; everyone has something inside that motivates him or her to be who they are. 2. People will go to great lengths to preserve their pride. Your task then is to select one of these themes and in a comparative essay, explain and compare how this message is revealed in 12 Angry Men and To Kill a Mockingbird, providing specific supporting examples from each text. Therefore, as you watch 12 Angry Men, you will need to take notes on the problems that the characters face, how these conflicts develop, and how they are resolved. Following the movie, you will then craft a response in which you explain how the chosen message (theme) is revealed in the book and the movie and support your conclusion with specific evidence from the film and the novel. You can draw on your own experiences and prior knowledge to judge the situations. For example, if you believed the message of the film (and the novel) is that â€Å"Prejudice obstructs truth†, you would support this conclusion with evidence from the movie and discuss how this truth is seen in life. Plan BEFORE you begin writing; use the tools provided to prepare for your essay. This assignment is worth 100 points. Your response should be well-thought out and organized, including: _ (x2) a well-crafted written introduction that funnels to your thesis (position on theme) _ (x3) organized body paragraphs supporting the thesis, showing how the theme applies to texts _ (x2) use of specific evidence and insightful interpretations of the whole stories _ (x2) a final conclusion about how the theme is revealed similarly/differently in both texts. (x1) writing free of grammatical errors that interfere with a reader’s understanding. Identifying the Characters For your writing assignment on this film you will need to identify the different jurors. We only know the names of two of them. To identify the others you can refer to them by their juror number, occupation, personality trait, or appearance. Juror #1 – foreman of the jury, an assistant coach Juror #2 – short man with the high voice who worked in a bank Juror #3 – angry man who had a son he didn’t speak to Juror #4 – wealthy stockbroker Juror #5 – demonstrated how to use the switch blade Juror #6 housepainter Juror #7 was in a hurry to leave because he had tickets to a baseball game Juror #8 – Mr. Davis, the man who persuaded the others that the boy may not be guilty Juror #9 – Mr. McArdle, the old man with the keen eyesight Juror #10 – was prejudiced against other races Juror #11 – watchmaker, a refugee from Europe Juror #12 – tall thin man with glasses who worked in advertising Funnel Method of Organization General Introduction General Conclusion Thesis about Point #1  ¶ about Point #2 Thesis Crafting Your Thesis Statement 1) What are the questions you are answering? Ex: How is the theme revealed in the text? Ex: How is this similar/different? 2) Decide what you think. Ex: Both texts use a trial to prove that everyone has something inside that motivates him or her to be who they are, but they use different people. 3) Include reasons/points with your position to show w hat you will talk about Ex: The book uses conflicts between witnesses to show people’s motives; the movie uses conflicts between jurors. ) Use transition words and phrases to make the relationship between ideas clear. Ex. Thesis: Although both the book To Kill a Mockingbird and the movie 12 Angry Men use a trial to show the theme that everyone has something inside that motivates him or her to be who they are, the book uses witnesses to show how people’s motives influence their actions while the movie uses jurors to prove this point.

In a clear and concisely reasoned 9, which addresses the work of the Essay

In a clear and concisely reasoned 9, which addresses the work of the author, Ernest Hemingway - Essay Example Most notably, he was one of the Americans who participated in the First World War although not as a soldier. During that war, he worked as a volunteer serving as an ambulance driver a vocation that saw him seriously wounded. This essay will highlight the outstanding features that defined Hemingway’s writing style. Some of his famous works such as, â€Å"The Sun also Rises† and â€Å"The Old Man in the Sea† will be used to demonstrate the uniqueness in his style. Prior to highlighting the writing style of Hemingway, it is important to establish the background of the period in which he lived and wrote his works. Being a 20th century author, he experienced many of the defining aspects of that century. As highlighted above, one of those aspects is the first and the second world war that altered the perception of many people in the globe. Worth mentioning is the fact that Hemingway was of American origin (Bloom 67). Therefore, one of his outstanding experiences is the desperation that defined many of the American citizens after the world war. Moreover, the post war period that was defined by the emergence of individualism, materialism, pessimism and degraded moral values are aspects of life that Hemingway lived to see. Without doubt therefore, these experiences serve to define some of the common themes in his works. He underwent the radicalization of that century a factor that was also similar to many of his contemporaries. Hemingway was interested in joining the army in his earlier years, but his failed sight denied him the chance. After the voluntary venture of being an ambulance driver, during a time when many atrocities of the first world war were being perpetrated, he later joined journalism. For a period of time, he was a reporter with one of the publications in Kansas city. His career in journalism served to influence his writing style, making it uniquely distinctive from that of his

INTERPROFESSIONAL WORKING Essay Example | Topics and Well Written Essays - 2500 words

INTERPROFESSIONAL WORKING - Essay Example Any illness or medical condition always worsens with the advancement of age, and thus it is very necessary that the patients should be given proper treatment as and when the time is abundant. But while looking at the case study of Mrs. Ivy, it is hard not to notice the negligence of various authorities and the mention of lexis such as â€Å"waiting list† and â€Å"Social services would not get involved without proper†¦Ã¢â‚¬  Selfishness is really a very amazing temperament of a human being – My point being, since Mrs. Ivy needed tremendous care and a supervisory body while she developed her Dementia, her daughter should have let Mrs. Ivy stay at her home rather than looking for a flat or government’s care centers. And there is not a mention of what her son did for her after the part that â€Å"he lives far away†. A person can not always expect the government to stand by their ‘parent’s’ side at their time of need. After all, it is logical to say, that the government can not possibly cater all the dying people. We as humans should also realize our responsibility and thus her children should have favored her to stay with either one of them. The government of Britain has set up various trusts and policies to help the elderly (particularly with mental problems such as Alzheimer, Dementia, etc. Some of the current active policies are as follows: As Mr. Tisdall notes in his book â€Å"Children, Young people and social inclusion: Participation for What?† (2006), the chief motive behind this policy states that it is really hard for children of mentally disabled parents to cope up with their parents, economic conditions and personal lives. Therefore, the government has set up this program to help the mentally disabled parents of such children to pass along the troubled times. This program by the government is basically focused on health related issues of asylums, refugees, minorities, and

Schizophrenia Essay -- essays research papers

Schizophrenia Schizophrenia is a serious brain disorder. It is a disease that makes it difficult for a person to tell the difference between real and unreal experiences, to think logically, to have normal emotional responses to other, and to behave normally in social situations. People with schizophrenia may also have difficulty in remembering, talking, and behaving appropriately. Schizophrenia is one of the most common mental illnesses. About 1% of the world population has schizophrenia. In the United States, there are about 2.5 million people with the disease. Schizophrenia is the cause of more hospitalizations than almost any other illness. Schizophrenia most commonly begins between the ages of 15 and 25. Although it strikes men and women equally, the symptoms may appear later in women than in men. Very rarely, the symptoms of schizophrenia can appear before the age of 12. Childhood schizophrenia has a more chronic disease course and involves poor early language development. People with schizophrenia can have a variety of symptoms. Sometimes, these symptoms come on suddenly. Usually, though, the illness develops slowly over months or even years. At first, the symptoms may not be noticed or may be confused with those of other conditions. For example, people with schizophrenia may feel tense, be unable to concentrate, or have trouble sleeping. They often become increasingly isolated and withdrawn as their grip on reality loosens. They do not make or keep friends. They may stop caring about the way they look. Dropping out of school or doing badly at work are other early signs of schizophrenia. As the illness progresses, symptoms of psychosis develop. The person starts to act strangely and talk nonsensically. People with schizophrenia may develop paranoid delusions. Examples of this would be that they might see, feel, smell, or hear things that are not really there. They may have physical symptoms, like frowning or unusual movements, and may stand or sit in strange positions. Some people become almost motionless. Others move around constantly. The severity of symptoms will vary from one person to another. The symptoms also tend to worsen and improve. When the symptoms are improved, the person may appear to behave relatively normally, but usually there will be re... ...therapy may help person with schizophrenia learn to sort out the real from the unreal. Group therapy may help them learn to get along with others. Self-help groups may help persons with schizophrenia feel that others share their problems. The best way to prevent relapses is to continue to take the prescribed medication. People with schizophrenia may stop taking their medications for several reasons. Side effects are one of the most important reasons that people with schizophrenia stop taking their medication. It is hard for people to put up with unpleasant side effects for months or years. It is especially hard when the person feels well. It is very important to find the medication that controls symptoms without causing side effects. Convenience is also important. Some medications need to be taken two, three, or even four times a day. Others may be taken just once a day. People are more likely to remember to take a medication once a day than several times a day. Some people profer to get injections every month of long-lasting medication. Taking medications regularly is the best way to prevent repeated illness and hospitalization.

Project Management Organizational Structures Paper Essay

Introduction At the start of every project, it is important to select the organization structure. There are three organizational structures the functional, matrix, and pure project structures. Each structure has its advantages and disadvantages. All three are different and when it comes to structuring a project the project managers is in charge of deciding which organizational structure is best fit for the project. This paper will focus on functional structure, matrix structure and pure project structure. Functional Project In a functional project structure, employees are departmentalized by task similarity, and projects are performed inside the departmental unit such as accounting, marketing and human resources departments are examples of units grouped together based on the functions they perform (Murray, 2014). Functional project structure is the most successful and oldest structure. In functional project structure components are divide into two a project is assigning to a functional manager who coordinates with others to assigning the project to different departments. Each department is in charge of completing their portion of the work and reporting to the department managers. Advantage and Disadvantages Functional structure project has both advantages and disadvantages. One of the advantages is the flexibility and staff contributions. Employees are switched back and forth between projects. The department will be able to provide professional and technical personnel and after completion of the work it can go back to his original work. The disadvantage is that this structure is not very effective when used on more complex projects. The individual accountability is not recognized. An other disadvantages the focus is not set on the client it is focused on activities rather than function, slow responses , lack of interest and motivation in certain areas, and difficulties in communicating.Difficulties in coordination is an other  disadvantage since project manager are only responsible for part of the project and others are responsible for other parts of the project. Matrix Project The matrix structure is a combination of both the functional and pure project organizational structures. The matrix structure was evolved from the flaws of the functional and pure project structures. In the matrix structure, functional managers and project managers have the equal powers. Since both functional and project manager are equal the staff generally works under two bosses. This structure works well when more than one project is being coordinated. Advantage and Disadvantage The advantage of the matrix structure is the highly skilled and capable resources can be shared between the functional units and important strategic projects. An other advantage is that efficiency is higher. A disadvantage is that staff has to report to two bosses, which can add confusion, and conflicts may arise since both bosses have equal authority and power. The disadvantages of the Matrix structure include balancing out who is in charge of the project, failure of project due to lack of negotiating skills, and balancing time, cost, and performance. Pure project The pure project structure dedicates it resources and self-contained staff to work full time on the project. Pure project structure is mostly used on complex projects since it strongly focuses on the work and completing the project. This structure reacts rapidly to the needs of clients contrary to those in the functional organizational structure. In this structure each project manager is appointed and is responsible to conduct all responsibility associated with the project. The project manager has full authority of the of the project. Advantage and Disadvantage The pure project structure advantages are that it is clear of who has the projects authority, it access special expertise, the project is focused and prioritized, as well simplified communications. This structure allows the project to be separated from the rest of the parent system becoming a self contained unit with its own staff, administration, and tying to the parent  firm through periodic progress reports and oversight (Meredith, 2012). In this structure staffs only report to on person so decisions are made quicker. Pure project structure disadvantages are include duplication of effort, rivalries, uncertain reintegration of resources and unclear motivations and loyalties as well goals and policies can be ignored. This structure disadvantages also include the transfers in technology and the use of resources, inconsistencies, and the project taking on a life of its own. Best Method Not any of the three organization structure is better than another. Each structure has its advantages and disadvantages as discussed above. When it come into choosing which organization structure to use decision depends on what the project manager is trying to accomplish. All three structures work differently depending on the project so the project manager has to decide which organizational structure best suits that project. In doing so the factors that contribute to the project manager decision are the available resources, finances, and the timeline that project needs to be completed. For the project to be successful the project manager must compare and contrast the three organization structures and decide which is most suitable. Conclusion Organizational structures show the methods that can be used by an organization. The use of these structures determine the success and improvement of the productivity in an organization. Each structure is used to improve how organizations report and communicate with the other elements within the organization. Organizational structures are viewed as guidelines to set in place to assist task performance to all involved in the project. Functional organization, Pure Project organization, and Matrix organization are the three most popular project management structures that are still used today due to their success.

Discovered Biological Functions Of Rna Health And Social Care Essay

Recently, the figure of ascertained biological maps of RNA has been increasing. In add-on, the range has been expanded, and therefore RNA is non merely a inactive courier of familial information from Deoxyribonucleic acid to proteins makers as had been thought earlier. It has been found that RNA plays of import functions in all of molecular biological science such as transporting familial information ( messenger RNA ) , construing the codification ( ribosomal RNA ) , and reassigning familial codification ( transfer RNA ) . It besides performs different maps which include: catalyzing chemical reactions [ 1 ] , [ 2 ] , directing the site specific alteration of RNA bases, commanding cistron look, modulating protein look and helping in protein localisation [ 3 ] , [ 4 ] . The map of RNA molecules determine many diseases caused by RNA viruses. Identifying the secondary construction of RNA molecules is the cardinal key to understand its biological map [ 5 ] . The RNA construction anticipation methods, is tremendously affected by the quality of alignment [ 6 ] . MSA significantly improves the de novo anticipation truth of proteins or RNAs structures [ 7 ] . For illustration, current RNA secondary construction anticipation methods utilizing aligned sequences is win in deriving higher anticipation truth than those utilizing individual sequence [ 8 ] . Multiple sequence alliance ( MSA ) has become widely used in many different countries in bioinformatics. Multiple alliances are present in most of the computational method used in molecular development to assist happening sequences household, predict the secondary or third construction of new sequences, RNA folding, cistron ordinance and polymerase concatenation reaction primer design [ 9 ] , foretelling maps, predict patient ‘s diseases by comparing DNAs of patients in disease find. MSA is the most natural manner to see the relation between sequences by doing an alliance between the primary sequences so that indistinguishable or similar residues will be aligned in columns. That is why this method is so called multiple sequence alliance ( MSA ) . At kernel, all widely MSA tools used to better the alignment quality of initial alliance [ 10 ] . The sequence alliance job can be considered as an optimisation job in which the aim is to maximise a marking map [ 11 ] . One chief challenge with MSA is how to gauge the quality of computer-aligned sequences. An nonsubjective map ( OF ) is required in the optimisation processes to happen the optimum alliance. The pick of nonsubjective map is critically of import in obtaining high quality alliances [ 12 ] . In add-on, OF acts an indispensable function in optimisation algorithms whereby there is a relation between the alliance mark with the mark computed by the alignment quality. MSA optimisation job is NP-complete [ 13-15 ] , which motivates, the research for heuristics [ 16 ] . Over the last decennary, the evolutionary and meta-heuristic are the recent attacks to work out the optimisation job. Consequently, most of practical MSA algorithms are based on heuristics to obtain moderately accurate MSA within moderate computational clip and normally produce quasi-optimal alliance. Many researches solve MSA job as optimisation job by utilizing familial algorithm [ 17, 18 ] , Particle Swarm [ 11 ] , ant settlement [ 19 ] , and Simulated tempering [ 20 ] . MSA job can be resolve as optimisation job based on harmoniousness hunt algorithm [ 21 ] to maximise the nonsubjective map and happen the optimum alliance. The purpose of this paper is to analyze and examined the correlativity of different nonsubjective maps utilizing standard sets of RNA datasets. The most straightforward OF is the sum-of-pairs ( SP ) score [ 3 ] , weight sum-of-pair [ ] , java [ 22 ] , Xstate [ ] and NorMD [ 23 ] . This paper is organized as follows: Section 2 introduce the multiple sequence alliance job. Section 3 explains the different nonsubjective map from the state-of-the-art. Section 4 explains the proposed methodological analysis. The rating and analysis methodological analysis that is used to measure our comparing is explained in Section 5. Last, Section 6 provides the decision and sum-up of the paper.2.0 Multiple Sequence AllianceA sequence is an ordered list of symbols from a set of alphabet S ( 20 amino acids for protein and 4 bases for RNA/DNA ) . In bioinformatics, a RNA sequence is written as s = AUUUCUGUAA. It is a twine over the set S of bases symbols Adenine ( A ) , Cytosine ( C ) , Guanine ( G ) and Uracil ( U ) : S = [ A, C, G, U ] . Alignment is a method to set up the sequences one over the other in a manner to demo the matching and mismatching between residues. A column, which has lucifer residues, shows no mutant is go oning. Whereas, the column with mismatch symbols shows that several mutant events are go oning. To better the alliance mark, the character â€Å" – † is used to match to a infinite introduced in the sequence. This infinite is normally called a spread. The spread is viewed as interpolation in one sequence and omission in the other. A mark is used to mensurate the alliance public presentation. The highest mark one is the best alliance. For lucidity ‘s interest, the generic MSA job is expressed with the following declaration: â€Å" Insert spreads within a given set of sequences in order to maximise a similarity standard † [ 24 ] . The MSA job can be divided into three troubles, which are scalability, optimisation, and nonsubjective map. Finding an accurate MSA from sequences is really hard. It is a clip consuming and computationally NP-hard job [ 13-15 ] . In fact, that complexness comes from that all three jobs must be solved at the same time. The first job is the scalability, which is to happen the alliance of many long sequences. The 2nd job is the optimisation, which is to happen the alliance with the highest mark based on a given nonsubjective map among sequences. Optimization of even a simple nonsubjective map is an NP-hard job. The 3rd job is the nonsubjective map ( OF ) , which is to rush up the computation in order to mensurate the alliance. Most modern plans for building multiple sequence alliances ( MSAs ) consist of two constituents: an nonsubjective map for measuring the quality of a candidate alliance of a set of input sequences, and an optimisation process for placing the highest scoring alliance with regard to the chosen nonsubjective map [ 25 ] .3.0 Objective mapsAligning multiple sequences is a extremely non-trivial undertaking ( in both a biological and computational sense ) whose truth in pattern depends mostly on the pick of input sequences, the cost ( or aim ) map, and the heuristics employed [ 26 ] . An of import facet of alliance mark is to set up how meaningful a given multiple alliance is. This is to find whether the aligned sequences are in fact optimum and to gauge the mark of the alliance in which there is no anterior cognition of the mention alliance. Objective map is the psyche of iterative algorithms in the sense that it determines the campaigner move to be taken to better the solution quality. In multiple sequence alliance, nonsubjective map Acts of the Apostless as the cardinal factor to command the development of an alliance into a mature one. Using optimisation algorithm to work out any job requires delegating a fittingness map. In harmony hunt algorithm, this map evaluates and ranks harmoniousnesss in the harmoniousness memory harmonizing to their tonss. Harmonies that ain good alliance mark in the harmoniousness memory are retained. In this subdivision different nonsubjective maps are studied. The pick of nonsubjective map is strictly a biological job that lies in the definition of rightness. A mathematical map able to mensurate an alignment biological quality that defines a right alliance and its expected belongingss is called nonsubjective map ( OF ) . Given a perfect map, the mathematically optimum alliance assumes to be biologically optimum. While the map defines a mathematical optimum, it is seldom that this optimum will besides be biologically optimum [ 25 ] . There are different nonsubjective maps to hit the quality of the alliance, viz. sum-of-pairs, leaden sum-of-pairs, and NorMD [ 23 ] , MstatX, amd COFFEE [ 22 ] . They are used in optimizing and iterative alliance methods to better the alliance by seeking to maximise the nonsubjective map [ 27 ] .3.0.1 sum-of-pairsPresently sum-of-pairs nonsubjective map is most widely used [ 28 ] . Carrillo and Lipman [ 29 ] foremost introduced the sum-of-pairs ( SP ) mark map, which defines the tonss of a multiple alliance of N sequences as the amount of the tonss of the N ( N-1 ) /2 pairwise alliances [ 29 ] , [ 30 ] . Although SP mark map has been widely used to measure MSA, it does n't truly supply any biological or probabilistic justification [ 30 ] . Each sequence is scored as if it is descended from the N-1 other sequences alternatively of a individual ascendant. As a consequence, evolutionary events are frequently overestimated. The job worsens as the figure of sequences additions [ 30 ] the sum-of-pairs ( SP ) mark described in [ 31 ] , [ 32 ] , [ 29 ] , [ 33 ] is used to cipher the nonsubjective map ( OF ) where there is no anterior cognition of the mention alliance. The general signifier of OF mark of alignment n sequences consist of m columns is OF = . Where is the similarity mark of the column myocardial infarction, is the spread punishment of the column myocardial infarction and is the sequence length. The similarity mark of the column myocardial infarction can be measured by the sum-of-pairs ( SP ) . The SP-score S ( myocardial infarction ) for the i-th column myocardial infarction is calculated as follows: S ( myocardial infarction ) = , ( ) where is the j-th row in the i-th column. For alining two residues x and y, the permutation matrix s ( x, y ) is used to gives the similarity mark.3.0.2 Weighted sum-of-pairsThe leaden sum-of-pairs ( WSP ) score [ 28 ] , [ 34 ] is an extension of SP mark so that each pairwise alliance mark otherwise contributes to the whole mark. A leaden SP mark map has been proposed in the manner to reflect the relationships between the sequences. The rule is to give a cost to each brace of aligned residues in each column of the alliance ( permutation cost ) , and another cost to the spreads ( spread cost ) . These are added to give the planetary cost of the alliance. Furthermore, each brace of sequences is given a weight related to their similarity to other braces. The WSP calculates a entire mark from the leaden pairwise mark of all the sequences. The undermentioned figure shows the mathematical preparation of the leaden SP mark map. WSP ( A ) = ( ) Where N is the figure of sequences, k the length of aligned sequences, is the weight given to a brace of sequences, and is the similarity cost of two symbol sequence ( ) . The cost map included spread gap and extension punishments for gap and widening spreads. The weight of pairwise aligned sequences may be proportionately score [ 35 ] , [ 36 ] harmonizing to the sum of alone information enclosed in the sequence. These weights try to diminish the influence of excess information from strongly related sequences. A weight represents a per centum equal to a per centum individuality ( PID ) calculated over each brace of aligned sequences [ 24 ] as follows ( excepting spreads ) : PID = ( )3.0.3 Normalized Mean Distancenormalized mean distance ( NorMD ) [ 23 ] is a normalized mean distance ( MD ) mark measures the normalized mean distance between the similarities of the residue braces at each alliance column, introduce in ClustalX, between similarities of residue braces at each alignment column. A mark for each column in the alliance is calculated utilizing the construct of uninterrupted sequence infinite introduced by [ 37 ] and the column tonss are so summed over the full length of the alliance. NorMD take into history the sequence information, such as the figure, length and similarity of the sequences to be aligned. NorMD is used in RASCAL [ 38 ] and AQUA [ 39 ] .3.0.4 Consistency markConsistency-based nonsubjective maps focus on improved marking of lucifers in early alliances by integrating information from of pairwise alliance. This consistence construct was originally introduced by Gotoh [ 40 ] and subsequently refined by Vingron and Argos [ 41 ] . Kececioglu [ 42 ] reformulated this job as a maximal weight hint ( MWT ) job. It was further expanded by Morgenstern [ 43 ] who proposed the first heuristic to work out this job for big cases. Consistency-based marking is used in T-Coffee [ 44 ] , MAFFT [ 45 ] , and Align-m [ 46 ] algorithms. The COFFEE [ 22 ] is a consistency-based which step optimized the figure of aligned residues that were besides aligned in planetary pairwise alliances of the same sequences. Coffee nonsubjective map which evaluates the consistence between a multiple sequence alliance and a antecedently defined library of pair-wise alliances. COFFEE required two constituents: ( I ) a set of pairwise mention alliance by utilizing any method for doing pairwise alliances, ( two ) the OF that evaluate the consistence between a multiple alliance and the pairwise alliances contain in the library. COFFEE plants by first bring forthing the pairwise library of the sequences in the alliance and so calculates the degree of individuality between the current multiple alliance and the pairwise library. COFFEE is non using excess spread punishments so that, it is non sensitive to the permutation tonss of amino acids, the mark is normalized, and the cost of similar braces is place dependent. Coffee is reflect the deg ree of consistence between a multiple sequence alliance and a library containing pairwise alliances of the same sequences. The planetary mark mensurating the quality of the alliance is computed by the undermentioned expression. Coffee mark = ( ) where Len is the length of the MSA ; Aij is the pairwise projection of sequences Si and Sj obtained from the MSA ; Wij is the per centum individuality between the two aligned sequences Si and Sj ; is the figure of residues braces that are shared between Aij and the pairwise. In add-on, utilizing chance in consistence leads to a alleged chance consistency. This hiting map is introduced in ProbCons [ 47 ] . It assigns position-specific permutation tonss based on a step of expected truth derived from a concealed Markov theoretical account. This thought is implemented and extended in the PECAN [ 48 ] , MUMMALS [ 49 ] , PROMALS [ 50 ] , ProbAlign [ 51 ] , ProDA [ 52 ] , and PicXAA [ 53 ] plans.3.0.5 POsition-Specific and consIstency-based nonsubjective function ( POSITION )POSITION [ 54, 55 ] is based on the consistence, it calculates the degree of individuality between the current multiple alliance and the pairwise library. The hiting map for POSITION is shown as under in Eq. ( 5 ) . POSITION = ( 5 ) where N is the figure of the sequences ; Aijl is the brace of residues at index cubic decimeter of the pairwise projection of sequences Si and Sj ; and Occurrence ( Aijl ) is a 0-1 binomial map of whether brace Aijl occurs in the pairwise library. W ( Aijl ) is the weight of Aijl and is assigned to the mean similarity of residue braces around index l. This is an attempt to specify the weight harmonizing to contextual information of residue braces.3.0.6 MaxZMaxZ is a statistical alliance quality mark introduced in [ 56 ] which first quantifies the grade of preservation at each alignment place and so counts the figure of significantly conserved places over the alliance. It used Zscore for mensurating the grade of preservation that is based on profile analysis [ 57 ] Then, by utilizing the importance trying method [ Using the SIR algorithm to imitate posterior distributions. ] , the statistical significance of an observed mark value is calculated. In footings of positional significance degrees, the full alliance mark is calculated.3.0.7 MstatXMstatX calculates the trident statistic of each column in the multiple sequences alliance. Then by stipulate the statistic with the flag options. It can gives many different statistical steps on columns of a multiple alliance like Shannon information, frequence counts, spread counts, and more sophisticated marking. The default statistic is a weighted-entropy which means a Shannon information based on chances computed with the sequence burdening strategy defined by [ 58 ] . Statisticss proposed in MstatX is based on [ 59 ] and [ 60 ] .3.0.8 Maximal expected truth ( MEA )Maximal expected truth ( MEA ) [ 61 ] : The basic thought of MEA is to maximise the expected figure of â€Å" right † aligned residue braces [ 62 ] . It has been used in PRIME [ 63 ] , and ProbCons [ 47 ] algorithms.3.0.9 Segment-to-segment nonsubjective mapSegment-to-segment nonsubjective map: It is used by DIALIGN [ 64 ] to build an alliance through comparing of the whole sections of the sequences instead than the residue-to-residue comparing.3.0.10 Profile markProfile hiting map uses a marking map which is defined for a brace of profile places. In add-on to SP, MUSCLE [ 65 ] uses a new profile map which is called the log-expectation ( LE ) mark. Some of these nonsubjective maps integrated into other nonsubjective maps, each have its ain advantages and disadvantages. The nonsubjective map presently used in DIALIGN that is segment-to-segment nonsubjective map is flawed [ 66 ] . On the other manus T-Coffee is excessively memory demanding [ 12 ] . Sum-of-pairs is the most popular marking method because of its comparative velocity and hardiness. The velocity advantage is chiefly because the sum-of-pairs method does non necessitate a tree [ 67 ] . Some nonsubjective maps use permutations matrices whereas other used consistence construct by involve pairwise alliance. [ 68 ] disadvantage of these permutations matrices is that they are intended to rate the similarity between two sequences at a clip merely, and in order to widen them to multiple sequences, it is common to happen that they are scaled by adding up each pairwise similarity to obtain the mark for the multiple sequence alliance [ 5 ] .4.0 Alignment QualityQ ( Quality ) is a quality map to gauge the comparing between the alliance and the mention alliance. Q mark is the figure of right aligned residue braces in the trial alliance divided by the figure of residue braces in the mention alliance. This has been termed as the developer mark [ 69 ] and SPS [ 31 ] .5.0 MATERIALS AND METHODSHarmony hunt algorithm – which is out of range of this paper – is used to happen the optimal or a close optimum alliance harmonizing to the nonsubjective map. Given a perfect map, the mathematically optimum alliance will besides be biologically optimum. While the map defines a mathematical optimum, it is seldom have an statement that this optimum will besides be biologically optimum. two type of dataset are chosen ( I ) the subset of BRAliBase which are extremely variable and suited for local MSA ; ( two ) LocalEXtR, an extension of BRAliBase 2.1, consisting large-scale trial groups and patterned on BRAliBase 2.1 ; The series of experiments has been conducted in order to analyze the relationship of the corresponding nonsubjective map mark with the alignment quality. The experiment has been done in the term of correlativity coefficient between the nonsubjective map mark and the alignment quality mark in one side and the consuming clip in another side. First, the different nonsubjective maps are used as a fittingness map in HS algorithm and the relationship between them are studied. Second compare the quality tonss of 5 nonsubjective map utilizing database In pattern, it is hence ever recommended to utilize as many different methods. hence analysis did non curtail to merely a few of the best alignment methods but aimed to utilize as many methods as possible [ 12 ] . One of the primary challenges in sequence alliance is to happen a biologically meaningful nonsubjective map. A common pick of many alliance algorithms has been the ‘sum-of-pairs ‘ ( SP ) mark, which merely takes the amount of the tonss of all pairwise alliances in a given multiple alliance. To day of the month, there is no nonsubjective map that has been every bit good accepted for multiple alliances [ 70 ] as similarity has been for pairwise alliance. Alignment quality requires a mention alliance from database benchmark. The comparing is between the trial alliance and the mention alliance and it is called here alignment quality.Performance ratingTwo scenarios are done in different manner, The first scenarios, it uses an nonsubjective map in the HS Improvising procedure and analyze the relationship between the alliance mark with alignment quality for concluding alliance. This is repeated with all nonsubjective map. The motive for mark the alliance many times in every loop was the fact that alliances generated prior to the several iterative polish are frequently rather different from the concluding alliance [ 12 ] . Second scenarios, it measures alignment mark and alignment quality for the same alliance which is the concluding alliance by every nonsubjective maps individually. Alignment mark and its quality are compared for each alliance. This seneraio is to compare the consequence of different nonsubjective map on the same alliance These experiments to cognize how strong is the relation between them in each nonsubjective map individually. A comprehensive reappraisal of all methods will non be given here, but the common nonsubjective maps will be focus on.a. Harmony hunt algorithmHarmony hunt algorithm ( HS ) is developed by Geem [ 21 ] . HS is a meta-heuristic optimisation algorithm based on music. HS is imitating a squad of instrumentalists together seeking to seek the best province of harmoniousness. Each participant generates a sound based on one of three options ( memory consideration, pitch accommodation, and random choice ) . This is tantamount to happen the optimum solution in optimisation procedure. Geem et Al. [ 21 ] theoretical accounts HS constituents into three quantitative optimisation procedure as follows: first procedure, the Harmony memory ( HM ) : It used to maintain good harmoniousnesss. A harmoniousness from HM is selected indiscriminately based on the parametric quantity called harmony memory sing ( or accepting ) rate, HMCR ?„ [ 0,1 ] . It typically uses HMCR = 0.7 ~ 0.95. Second procedure, the pitch accommodation: it is similar to local hunt. It is used to bring forth a somewhat different solution from the HM depend on pitch-adjusting rate ( PAR ) values. PAR control the grade of the accommodation by the pitch bandwidth ( brange ) . It normally uses PAR = 0.1~0.5 in most applications. Third procedure, the random choice: a new harmoniousness is generated indiscriminately to increase the diverseness of the solutions. The chance of randomisation is Prandom = 1- HMCR, and the existent chance of the pitch accommodation is Ppitch = HMCR A- PAR. The pseudo codification of the basic HS algorithm with these three constituents is summarized in Figure 1. Harmony Search Algorithm Get down Declare the nonsubjective map degree Fahrenheit ( x ) , ten = ( x1, x2, aˆÂ ¦ , xn ) Initialize the harmoniousness memory accepting rate ( HMCR ) Initialize pitch seting rate ( PAR ) and other parametric quantities Initialize Harmony Memory with random harmoniousnesss While ( t & lt ; max figure of loops ) If ( rand & lt ; HMCR ) , Choose a value from HM If ( rand & lt ; PAR ) , Adjust the value by adding certain sum End if Else Choose a new random value End if End while Measure the solution by utilizing nonsubjective map Accept the new harmoniousness ( solution ) if better Update HM End while Find the current best solution in HM End Figure 1 Pseudo Code of the Harmony Search Algorithm [ 71 ] The HS algorithm has been applied to assorted optimisation jobs [ 72 ] that include Real-world applications, Computer scientific discipline jobs, Electrical technology jobs, Civil technology jobs, Mechanical technology jobs, and Bio & A ; medical applications.B. Benchmark DatasetThree type of dataset are chosen ( I ) the subset of BRAliBase which are extremely variable and suited for local MSA ; ( two ) LocalEXtR, an extension of BRAliBase 2.1, consisting large-scale trial groups and patterned on BRAliBase 2.1 ; ( three ) Lset, a brace of large-scale trial sets representative of current biological job. The subset of the BRAliBase 2.1 are selected from the most variable dataset within the suite. They are from THI, Glycine riboswitch and Yybp-Tkoy RNA households, and contain 232 trial datasets. LocalExtR uses the same seed alliances from Rfam that BRAliBase uses and signifiers big trial groups. BRAliBase is label a trial group qi, where I is the figure of sequences for each trial set in the group. The tabular array ( 1 ) and ( 2 ) show the inside informations of the dataset and the description information about each trial set.

Therefore, an nonsubjective map ( OF ) is required in the optimisation processes. The pick of nonsubjective map and heuristics is critically of import in obtaining high quality alliances [ 12 ] . In add-on, OF acts an indispensable function in optimisation algorithms whereby the alliance is optimized against a mark computed by the OF [ 2 ] . The most straightforward OF is the sum-of-pairs ( SP ) score [ 3 ] , weight sum-of-pair [ ] , java [ 22 ] , Xstate [ ] and NorMD [ 23 ] .5.1 Correlation between Objective maps Score and alignment qualityTheoretically, an OF should ever give higher tonss for alliance with better quality [ ] . In world, nevertheless, since the nonsubjective map tonss and the alliance qualities are measured utilizing different standards, incompatibility happens. Correlation between alignment quality and different nonsubjective maps score were practiced on each experimental. Correlation coefficients ( R2 ) were so computed for each nonsubjective map and Q mark of the alignment quality. Two scenarios are performed to look into the correlativity the first one where utilizing the nonsubjective map as the HS Improvising procedure, the 2nd one where mark a concluding alliance by different nonsubjective maps. ( a ) First Scenario: utilizing the nonsubjective map in the generator procedure Five experiments are carried by utilizing an nonsubjective map and compared alignment mark with alignment quality in each experiment. Each experiment has been repeated 5 times for the same dataset and the norm is calculated. In this experiment, each nonsubjective map have been used individually as a fittingness map. Then, the correlativity of the nonsubjective map mark and the alignment quality mark is calculate utilizing the Correlation coefficients ( R2 ) . Each instance has been repeated 5 tallies for same dataset and calculated the norm for each nonsubjective map theoretical accounts. The figure of loop in each tally, is fixed in all the experimental in this experiment to 10,000. 322 trials set are used and their inside informations are summarized in Mistake: Reference beginning non found HS parametric quantities and others parametric quantities are setup to default puting for all nonsubjective map. Alliance Generator OF1 Alliance Mark |qualityaˆÂ ¦Alliance Generator OF2 Alliance Mark |qualityaˆÂ ¦In this experimental BHS-MSA is used to bring forth the alliance. Within the optimisation processes the nonsubjective map theoretical accounts, sum-of-pairs, weight sum-of-pair, java, Xstate and NorMD were used individually to give the good alliance quality. The concluding alliances were measured and evaluated by comparing with the mentions utilizing the rating map Quality ( Q ) and Entire column Score ( TC ) . The mean correlativity coefficient value of all dataset is listed and the spread secret plan graphs are listed as shown in Figure 2. shows the R indicated that the java and sum-of-pairs nonsubjective map has better positive correlativity with alignment quality than others does. The relation is positive that mean when the nonsubjective map is increase the alignment quality is increase this is clear shows in the Figure 3.

In this experimental, 10 experiments are transporting out and alliance are bring forthing indiscriminately. Final alliance is measured by each nonsubjective map individually. Then, the correlativity of the nonsubjective map mark and the alignment quality mark is calculate utilizing the Correlation coefficients ( R2 ) [ 12 ] . This scenario is to back up the old 1. The correlativity on different nonsubjective map on alliances is study here by another manner where the nonsubjective maps are step the same alliance together and the relationship between the alliance mark with alignment quality are studied individually for each nonsubjective map. For ocular review, matching spread secret plans for all nonsubjective maps are presented.

The clip complexness of calculating an nonsubjective mark additions linearly with length of alliance and the figure of sequences.

Coffee and sum-of-pairs nonsubjective maps have the highest correlativity. Based on the clip cost shown in Table5: Time cost of each Test Group and figure 4, the cost clip used by sum-of-pairs is better than java nonsubjective map for all trial groups. Figure aˆZ4: Coffee and SPS Objective map clip6.0 DecisionThe alliance of multiple sequences remains a challenging job today. Here, we do non discourse possible schemes to better alliance quality, but alternatively concentrate on the maps used to measure the quality of completed alliances. The relationship of the alliance mark and alignment quality of different nonsubjective map is the aim of this paper. It is recommended to run several maps and compare their consequences to happen the most suitable one. The consequence shows that the correlativity between the alliances tonss and the alignment quality utilizing the COFFEE nonsubjective map and sum-of-pairs were better than those found utilizing the NorMd, MstatX, and WSP nonsubjective maps. Coffee and sum-of-pairs nonsubjective maps have the highest correlativity. It besides shows that the alliance marking by sum-of-pairs is better than java nonsubjective map for all trial groups in footings of consuming clip The tonss produced by sum-of-pairs and java are better correlated to the existent alliance truths than tonss produced by other methods.7.0 RecognitionThe writers would wish to appreciate the School of Computer Sciences every bit good as University Science Malaysia for their installations and aid.

The Halloween Storm of the Century in 1991

The Halloween Storm of the Century in 1991 The Perfect Storm was a rare monster storm with an unnamed hurricane in the center of the tempest. The perfect storm was a nickname given  to this storm by Bob Case, a retired NOAA meteorologist. The storm began as an extratropical low on October 28, 1991 and became famous as author Sebastian Junger profiled the sinking of the swordfishing boat the ​Andrea Gail in the novel The Perfect Storm. The storm would eventually produce 100-foot ​rogue waves. October Weather Conditions In October, most of the United States moves towards the cold winter months as the country slowly cools down from the summer heat. Ocean water has a high heat capacity meaning the landmasses of North America cool at a more rapid rate than the ocean waters. The heat retained in the Atlantic will often create massive storms in the still-warm waters. Because air masses retain the characteristics of their source, the continental air masses from the cooler land will often meet the maritime air masses of the warmer ocean creating large storms known as a Noreaster. Predicting the Perfect Storm Forecasters had a rough time forecasting this Halloween storm. The storm happened when a high-pressure system, a low-pressure system, and the remnants from Hurricane Grace collided in a trilogy of terror. The resulting waves and high winds hit many parts of the Eastern United States causing the famed sinking of the Andrea Gail and the death of her six passengers. An interesting aspect of the huge system was its retrograde motion (east to west)- not away from the New England Coast, but toward it. Even while New Englanders were enjoying clear bright blue October weather, forecasters were warning of this immense storm. A Rare Weather Event According to Bob Case, the set of meteorological circumstances leading to the storm happen only every 50-100 years. Much like the Fujiwhara Effect, several weather events (detailed at the bottom of the page) did a strange meteorological dance around each other. Storm damage hit as far south as North Carolina, Florida, and the Northern coast of Puerto Rico. The storm caused millions of dollars in damages to beaches and homes, including the seaside Kennebunkport, Maine home of former President George Bush. An Unnamed Hurricane A remarkable event occurred when a hurricane formed inside the Halloween Noreaster. Wind speeds topped 80 mph inside of the intense Halloween storm, making the storm of hurricane strength on the Saffir-Simposon Scale. This particular hurricane was never named as most tropical cyclones are named according to a pre-set list of hurricane names. Instead, it would become known as the Unnamed Hurricane of 1991. The storm finally broke up over Nova Scotia, Canada, on November 2, 1991, and remains only the 8th hurricane never to be named since the naming practice began in the 1950s. Why Wasnt the Hurricane Named? There is a difference between the Halloween Storm of 1991 and the hurricane that formed inside the storm. At the time of the storm, emergency officials and the media were scrambling to get more information on the storm damages and well as any forecasts for future problems. It was decided that the hurricane would be short-lived and should remain unnamed so as not to confuse people. Storm Records Broken Many locations up and down the Atlantic coast saw tide, flood, and storm surge records broken. In Ocean City, Maryland, a record high tide of 7.8 feet occurred beating the old record of 7.5 feet recorded during a March 1962 storm. Damages in Massachusetts topped $100 million dollars. Other specific facts are available from the National Climatic Data Center Damage Summary for the Perfect Storm. Causes of the Storm of the Century Hurricane Grace - On October 27, 1991, Hurricane Grace formed off the coast of Florida. As Grace moved north on October 29, an extratropical cyclone formed over Canada. The counterclockwise motion of this low-pressure zone left a trailing cold front over much of the Northern Atlantic coast. The cold front would later catch up with the dying hurricane. Grace would later make the retrograde turn to the east in response.A Low-Pressure System - The low-pressure system formed over Canada and ran into Hurricane Grace off the coast of Nova Scotia, tearing the already downgraded hurricane apart. There was intense wind shear that acted as a hurricane-breaker, but the low-pressure system absorbed much of the energy of Hurricane Grace. The low-pressure system reached a peak intensity of 972 millibars of pressure and maximum sustained winds of 60 knots on October 30. The later movement of this low-pressure system over warmer 80 degree Gulf Stream waters served to intensify the storm in the same way tropical storms are intensified by warm ocean waters in the tropics. A High-Pressure System - A strong high-pressure center extended from the Gulf of Mexico northeastward along the Appalachians into Greenland. Strong winds were generated from the tight pressure gradient between a strong high high-pressure in eastern Canada (1043 mb) and the surface low.

Criminal law undergraduate Essay Example | Topics and Well Written Essays - 1250 words

Criminal law undergraduate - Essay Example Thus, if a doctor applies skill and care and functions in a style that is considered as an adequate practice, he would not be regarded functioning negligently despite a successful medical result cannot be assured. Where a doctor is found guilty of total negligence or has done a crime through malevolent intent to assault or harm a patient, this may end in a criminal prosecution. To face a criminal action by doctors is extremely a rare event for doctors in their professional capacity. If a doctor anticipated serious injury to the patient and done gross negligence by prolonging with the wrong medical procedures without the required consent or induced intentional harm, in such a scenario, a doctor will face a criminal prosecution. In Kent v Griffins 2000], an ambulance was called by a doctor to shift a person to a hospital who was suffering from asthma. The control room replied to the doctor in affirmative. However, there was a failure on the part of ambulance to arrive in a reasonable time and as a result, the person suffered a heart attack which could have averted if the ambulance arrived in time. Claimant was succeeded. In this case, the doctor was not directly responsible for the sufferings of a patient but due to late arrival of an ambulance. (The Thomas Hardye School 2010). In Barnett v Kensington Hospital 1969], three night watchmen went to a casualty hospital and complained severe vomiting and stomach pain after drinking tea in a shop . When the duty nurse contacted the duty doctor, he refused to come and suggested that they could visit their own doctors. One of the watchmen went to home and after few hours, he was dead due to arsenic poison. The claimant sued the doctor. The claim was not successful, mainly due to the fact that by the time the doctor was requested to check up the watchmen , the poison would have taken hold, and the watchmen’s fate was sealed

Strategic Marketing Management - Case Study Example However, road to foray into such diversified markets was not that easy and needed an innovation from Dell’s management and policy makers. This innovation was not restricted only to new strategies or tactics, but to a complete revamping of its culture and the way employer-employee relationship exists. Question 1 Dell had been operating as the Numero Uno player in the computer industry, leaving behind IBM and Compaq. All credit to its innovative direct-to-sell model. However, Michael Dell (CEO and Founder of Dell Corporation) felt the need to innovate further and extend the targets because according to him, golden sales figures are not always real and most of the times, they carry hidden threats. Even though Dell had been posting mammoth profits in its computer sales, yet innovation was required because of spreading discontent among Dell employees and diminishing influence of leaders. The innovation at Dell was the precursor to its expansion and diversification spree and as such , required a total revamping of the prevailing culture and norms. Every strategy comes attached with strengths and also some defects. Innovation strategy at Dell was strong in its inception and planning aspects because the leaders had smelled the nuances of employee detachments with the Corporation. As such, the innovation strategy was marked by a transformation in the personality and attitude of the leaders itself- Michael Dell and Kevin Rollins. This sparked new zeal, influence and respect amongst the employees that even the senior managers and company owners are so committed to innovate the company that they are ready to change the way they behave. Infusing cultural compatibility was the stepping stone and indeed one of the strengths of the innovation strategy pursued at Dell (Interaction Associates n.d). Two-in-a-box approach was another inspiring and influencing feature as well as strength of the innovation strategy (Park 2003). It fostered team spirit, shared working and syner gistic attainment of goals when two managers or employees worked in tandem. Another strong feature of Dell’s innovation strategy was judiciously planned and analyzed options. The motto behind innovation strategy was ‘efficient and not profitable operations’. This is why Dell even let go of many of new ventures and entry options which seemed lucrative but did not hold much scope of future promise. Innovation should not be at the cost of current positioning and secured market standing. Dell could have proceeded with the options, but what matters is the value which should be delivered to the customers in terms of efficiency, reliability and value (Dell 2002). This is what the biggest strength of innovation strategy was. However, being too rigid on pursuing strategic options and not developing the research and development abilities of the company counts as one of the weaknesses of its innovation strategy. Dell embarked upon many ventures but discontinued them in midw ay because of cost or feasibility options. This is something which is not expected out of an experienced and leadership position holding giant. Innovation is a risk-return tradeoff which was not understood and recognized by Dell. Some sort of employee induction problem is also apparent from the case which unveils concerns like absence of bottom-up management approach, lack of empowerment and creativity in employees and decisions flowing in from the top management cadre of the company. Question 2 Whatever market Dell enters or
