An Article on Facebook from the Times of India Essay

For once, I was ahead of the curve, and, having rarely been in this exalted place, I can tell you it feels good. The backlash against Facebook, the social networking site, has begun, with rumblings of discontent being heard from distant corners of the globe. Word is going round that it is time-wasting, trivial, and a pathetic substitute for meeting friends in person. This is precisely what I have been saying to my friends all along but they used to recoil in horror as though declining to open a Facebook account was like refusing to bathe. They muttered darkly about certain people being pig-headed. I was reated like a Luddite, vainly holding out against penicillin or the electric kettle. Every time i asked them what exactly was so wonderful about this site, they gave the same feeble answers. Oh, it’s a great way to keep in touch. You can post your photos on it. Through the links to other people’s pages, you can see what your ex-boyfriends or ex-husbands are up to. Well, according to me, this is a waste of time. I can barely keep in touch with the friends who really matter to me four to five at the most, at any given stage in my life much less maintain an online relationship with old college friends or colleagues from years ago. If one has never bothered to make contact with them in all these years, it’s because one has never needed or particularly wanted to. It means that they don’t matter hugely to me now. They did then, but now i’m in touch with another set of friends. My life is full enough with them. If one has a spare few hours, one would rather meet a friend over coffee or wine. That real-time, face-to-face conversation is contact, not exchanging trivia online. Why would i want to see a friend’s holiday snaps when i can barely summon up enough interest in my own to get them developed? Few things, bar waiting for milk to boil, are as boring as other people’s holiday pictures. Much as i love my friends in various parts of the world, i’m perfectly content with a ‘broad brush’ update. An occasional e-mail telling me they are fine, their teenage son hasn’t become a drug dealer and their dog’s arthritis is better is fine with me. Any more detail is redundant. I assume they are equally uninterested in the daily mundaneness of my life and that is exactly as it should be. Even assuming i wanted to sign up, i would never have the time. If i, blessed with two maids and only one child to look after, cannot find the time to go on this site, how do millions of others, particularly those in the West who have many household chores, do so? hurry! No wonder companies are banning this site. God knows what it is doing to global productivity. But even outside work, don’t people have to walk the dog? Check up on an elderly aunt? File their tax returns? The Facebook phenomenon has confirmed yet again what we have always known that human beings are sheep. They see someone going off in one direction and they follow blindly for no apparent reason beyond the comfort of numbers. All my efforts at persuading my 12-year-old son not to get onto Facebook failed. I spoke cogently about the charm of being different, of having the moral strength to resist peer pressure, of the infinitely greater pleasures of reading, but my efforts failed. His school friends looked at him as though he had gone soft in the brain. As for twitter, don’t even get me started. The very name cutesy and twee irritates the hell out of me. Facebook and twitter are fads. Like all fads, they’ll end up in the dustbin, not of history, but of history’s footnotes.

Backup

Backup or backing up refers to the process of making copies of data to save and restore the original data incase of loss event also known as disaster recovery. Backup is so important in view of the fact that loss of data often happen in most machine users as their computers are habitually in the high risk of going wrong, failure in the hard disk does happen. The most common problems today that may result in loss of data are the threat to viruses. Although some viruses do not affect the file or the computer itself, some does and may even infect the hard disks of your computer resulting in data loss. David Smith estimated that 6% of all the personal computers suffer data loss every year (Boston Computing Network, 2010). Also, about 31% of PC users have experience data loss due to uncontrollable events (Boston Computing Network, 2010). When do you take backup (daily, weekly, on significant changes to data)? I personally do not set a specific schedule for backing up files because it has my habit to save a copy of important data. I also backup files when I make changes to them and so there is no need to have a schedule time for taking backup of files. In case of accidental loss of data, I do not have to worry since I have copies of all the files that are important to me. Do you schedule backups automatically? If so how? If not, how can you be sure to do them? No, I do not schedule automatic backups. As I have mentioned, it has been my habit to take backups whenever significant changes are made to my files. Thus, I am certain to have copies of all the files that I need. How do you take backup – manually, using the Copy facilities in the Windows Explorer? If so, describe the process; or do you have some other backup program? If so, what is it, and why do you like to use it? I take backups manually. I have to plug the storage device and manually save the data in order to create copies of it. I do not use back programs since I do not view taking backup as a task but rather I see it as an enjoyable thing to do since it gives me the certainly that in cases of data loss, I always have a copy. Where do you store the backup files (ie on what device and in what physical location) and why did you make that choice? Include costs, if any)? I have two primary devices used for data storage; flash disk and external hard disk. I used the flask disk for files that require changing in a short period of time, mostly school stuffs. On the other hand, I use the external hard disk for files that I rarely use as well as for large volume files. Still, I also use CDR’s for data that I wish not to be changed, mostly program files and installers. In the case that I am employed and required to use my personal computer for work related task, the only threat that I see is the privacy which can easily be handled by organizing files and folders. I believe that there would be no significant changes that must be done but I would need another hard disk in order to maintain that organization of my files. My original hard disk will be used for the backups of my personal files while the other will be used for work related documents. I would also have to change the allotment on my PC in order to cope with the changes. I will have to create partitions on the disks in order separate personal to work use: one partition for work use, one for personal use and another extra partition for other files. My flash disk would serve the same purpose as before, for files that often requires changes but both for personal and work related task. Thus, the only cost associated with the changes is another external hard disk for work related files as well as the time for making necessary changes.

Medical Malpractices Lawsuits and Their Changing Nature Essay

Medical Malpractices Lawsuits and Their Changing Nature - Essay Example D. The fourth step is establishing the causation in the medical malpractice suit. E. Finally, there is passing of judgment and the sentence based on evidence adduced. III. Discussions on the changing nature of medical malpractice suits influenced by the lack of national standards and federal government laws and statutes while using several examples in various states IV. The rising costs of damages in medical malpractice that underlines the need for further reform in medical malpractice laws. V. Conclusion and further suggestions for reforms in medical malpractice law Medical Malpractices and Their Changing Nature The law on medical malpractices and insurance has been under scrutiny and focus for many years across the United States and over the world. In recent years, Washington is realizing the need to support legislation meant to put a cap on the amount of litigation while restricting the amount of awards on damages resulting from medical malpractice suits. ... On the other hand, there are those who belief that the blame squarely lies on the insurance market for medical malpractice. This expose elucidates on the issues central to medical malpractice suits and their changing nature. Therefore, the expose begins by giving an overview on the operations of medical malpractices law and the procedure towards the awarding of damages in a medical malpractice lawsuit. After an analysis of medical malpractice law and lawsuits, the expose gives an investigation of the changing nature of medical malpractice law. Thereafter, there is an in-depth investigation of the cost factor in damages awarded to patients harmed by medical practitioners while finally the paper proposes further reforms in the tort law on medical malpractice in the concluding part of the expose. Medical Malpractice Law and Suits The jurisdiction of medical malpractice laws in the country is traditionally the preserve of state governments and not under the federal government. In this re gard, the legal rules and the operational framework that guided medical malpractices were precedents from states courts instead federal laws and statutes. Thus, medical malpractice laws were common laws since they were legal rules established by the state courts. In this effect, since the laws set in judgment and settlement from a state has no weight in another state, the laws and framework for handling medical malpractices varied, and still does to some extent today, from one state to the other state regardless of similar principles. Speiser points out that, the law on medical malpractice has its origin from English common law of the nineteenth century. However, the law that developed to medical malpractice law is an

Electronic Surveillance of Employees Research Paper

Electronic Surveillance of Employees - Research Paper Example This research will begin with the statement that to keep personal confidential information of a person intact and should not be disclosed to any other irrelevant person shall come under the purview of Privacy. The disclosure of such information may cause emotional distress to a person whose information is kept in confidence. In order to monitor the activities of a person or place to detect discreet activities through electronic devices like cameras, video cameras, tape recorders, microphones, and wiretaps come under the category of surveillance through electronic means. The identified instruments can be utilized in a competent court of law as evidence against violators. Multinational Corporations and corporations of repute use electronic surveillance system to ensure foolproof security and safety within their administrative jurisdiction. An employee can expect privacy at least in those places where hidden cameras or microphones are not fitted such as kitchen, dining room, washroom, s moking corner or petty stationary stores. Employees should know what is permissible and what is not permissible for them in accordance with employer’s privacy policy. Initially, the employer and the employee must have signed the document of the privacy policy to be complied in letter and spirit by the stakeholders. In fact, the employee has given the liberty or the rights to monitor his/her activities whether his/her activities are purely professional or personal. Non-compliance with privacy policy surely invites the displeasure of the management. In the United States of America, Electronic Communication Privacy Act (ECPA) 1986 has given the rights to the employers to monitor job-related conversations of its employees. By virtue of this act, employers enjoy complete freedom to listen incoming and outgoing calls. It hardly takes a minute or two to decide whether the calls so received or dispatched are personal or job related. With this freedom employer can measure the employee ’s sincerity and integrity with the company besides his/her professional competence. The prerogative to differentiate the incoming and outgoing calls of employees still lies with the employer and not with the employee (Lyon, 1994). 2- In this modern age and time, one cannot deny the benefits of technological advancement to prevent any unpleasant situation. By dint of computer technology, it is easy to monitor the activities of any employee by the employer at his/her workplace even at a remote location. Many of the employers allow their employees to have an access on the social sites of Internet. To keep the company environment friendly, the employer should provide space at work place for a chat where one can not disturb him or their conversation may not come out of the space to invite others attention (Mishra & Crampton, 1998). This will definitely improve the performance of a company since unnecessary strictness on the employees may have an adverse impact on their job relate d activities. We cannot deny the fact that â€Å"Happy laborers work more†.  

Intellectual propert law Essay Example | Topics and Well Written Essays - 4000 words

Intellectual propert law - Essay Example Moreover, Betty’s business was apparently called â€Å"Betty’s† from the period spanning 1986 to 1994. However, the name â€Å"Betty’s† was never officially trademarked, at least the facts do not indicate that it was. If the name was trademarked, then obviously Betty would have a stronger case. However, Betty might have a cause of action for passing off. Passing off, traditionally a tort that referred to attempting to represent one’s goods as the goods of somebody else, has the modern definition of using a person’s goodwill and reputation in an attempt to benefit oneself, and, in the process, injuring the original person’s good name, reputation and connections (Taittinger and others v. Allbev Ltd. and others [1994] 4 All ER 75). There are five elements in the tort of passing off, and they are â€Å"1. A misrepresentation 2. Made by a trader in the course of trade, 3. To prospective customers of his or ultimate consumers of good s or services supplied by him 4. Which is calculated to injure the business or goodwill of another trader (in the sense that this is a reasonably foreseeable consequence and 5. Which causes actual damage to a business of goodwill of the trade by whom the action is brought or will probably do so (Erven Warnick BV v. J Townend & Sons (Hull) Ltd. [1979] 2 All ER 927). In examining these elements, it is unsure whether Betty can prevail on the tort of passing off. The first element is that there must be a misrepresentation. Calling her company â€Å"Betty’s Produce,† when Jenny had previously worked for Betty for a long period of time, and Betty’s business was known as â€Å"Betty’s† for a number of years would certainly seem as if Jenny is misrepresenting her own produce as Betty’s. Jenny was no doubt highly associated with Betty in the mind of the consumers and the people to whom Betty catered, so those people probably would assume that Jenny w as still with Betty, and that Jenny’s produce was Betty’s produce. Jenny would be using Betty’s name in the course of trade and to prospective customers, and these same customers were also Betty’s customers, so those elements are satisfied as well. Whether it was calculated to damage the goodwill of Betty is a question for which there is no clear answer. Certainly it seems that Jenny was attempting to capitalize on Betty’s goodwill and reputation, but whether or not she wanted to injure Betty is questionable. However, as long as damage to Jenny’s reputation is reasonably foreseeable, this element is satisfied as well. Betty worked hard to establish a firm reputation for her products. Jenny’s products might not have the same standard. If Jenny’s products are not the same standard as Betty’s products, then Jenny would be damaging Betty’s reputation. â€Å"a misrepresentation by B that his inferior goods are of a su perior quality, which is that of A’s goods, whereby people buy B’s goods instead of A’s, is actionable† (Reckitt and Colman Products Ltd. v Borden Inc. and Others, [1990] 1 All ER 873). Jenny was clearly trying to represent her products as Betty’s products, in an effort to get these restaurants to buy her products instead of Betty’s products, so this element is satisfied as well. As to the final element, that the passing off causes actual damage to Betty’s reputation, actionable damage can be that which is gradual depreciation to the reputation that Betty

Education - Essay Example In contrast to such medicinal procedures Eastern medicine in some cases support the use of acupuncture and may even reduce stress. Effects of acupuncture would not be explained through traditional medical models and patients have experienced stress reduction by using acupuncture. The physiological effects of acupuncture can also be theoretically supported with evidence and in this essay I would argue which model of philosophy best fits in with our own belief systems and how this claim could be justified or established. The focus here is thus on differentiating and yet finding common grounds between constructivist and positivist philosophies. The similarities and differences of these two systems of thought could be highlighted not only with regard to stress but several other examples could be used to show exactly where these two systems vary and how they would differ. Positivism relies on strict scientific method and empirical understanding of events. Advocated by Comte, Popper and by scientists, positivism was considered as the most important approach to philosophy of science that could bring about scientific progress with natural or material approaches defined or understood empirically (Mill, 1993). Positivism is generally considered as the scientific method as science is based on certain statements which are empirically testable and verifiable (Morris, 2006). The logical structure and coherence of these statements would make a phenomenon scientifically explicable and only then this would be accepted as explaining the events of the world. Positivism being the best scientific explanation is also closely related to reductionism which shows how one type of entity would be reducible to another. The basis of positivism would relate to quantitative and objective measurement of the events or phenomena studied. Scientific information is thus informatio n that can be quantified and objectively studied. Apart from

Community college reflection Assignment Example | Topics and Well Written Essays - 500 words

Community college reflection - Assignment Example The faculty to student ratio is very low and therefore the classrooms are so small that students are able to get the attention of the professors for any challenge they encounter as well as feedback (Staley, 2011). This helps in boosting their knowledge and skills to get gainful employment as well as form a sound foundation for those endeavoring to attend university. The purpose of community colleges is to prepare students before they join college as well as empowering working adults to take part time specific courses while working. Although most community colleges have unique missions, the primary concept is based on their commitment to offer lifelong education, teaching, community service, and service to all society segments through fair treatment of the students. The breadth and relevance of program offered in community colleges is lower than that offered in universities since most of the students enrolled are credit students who need to boost their grades in order to be eligible for undergraduate courses. As such, the scope of their course lie between the high school and college level. Nevertheless, their program are highly relevant as they are sufficient in equipping local students with meaningful skills to handle employment. After my high school graduation, I enrolled for a certificate course in a community college for two years while awaiting to get admission to the university, since it would increase my chances of getting admission. I preferred the community college as it was low-cost compared to other colleges and the learning environment was very rewarding and fulfilling since I got to interact directly with the professors due to the small sizes of the classroom and the students were relatively

Assignment - Essay Example As much as they are like so are these sculptures different. Some contrasts are noted here. StandingMale Figure with Nails appears to be mostly wood; whereas, Reliquary of Sainte Foy is gilded. Furthermore, StandingMale Figure with Nails appears to be the image of a yoked and tortured African; while Reliquary of Sainte Foy is the image of an enthroned European. Moreover, StandingMale Figure with Nails appears to be steel encrusted, and Reliquary of Sainte Foy appears to be jewel encrusted. These differing views of the human condition are strikingly dissimilar. This study of StandingMale Figure with Nails (Nkisi Nkondi) and Reliquary of Sainte Foy yield a greater appreciation for each piece. Here, we conducted analysis of both comparison and contrast to seek a deeper understanding of their meaning. These sculptures represent two ways of honoring the human condition. One is natural and rugged and somewhat scary to think about, but the other is enlightened and uplifting and bright.

Incident Response, Business Continuity and Disaster Recovery Plans Case Study

Incident Response, Business Continuity and Disaster Recovery Plans - Case Study Example In addition, it is also compulsory to identify assets that may not limit to employees, information, hardware/network devices, financials, legal counsel, security and locations for facilitating BCP. The BCP increases the image of an organization among the employees, shareholders and consumers through representing a positive approach. Importantly, an effective BCP recognizes the link between human and assets. 15 Organizations are always at probable catastrophe for instances tornadoes, floods, blizzards, earthquakes and fire mishaps. However these are known natural disasters but other risks include power and energy distractions, sabotage, cyber assaults, hackers, infrastructure, transportation and security failure. Moreover, ecological disasters for example pollution and harmful materials spills are also a possible risk for organizations. Therefore, generating BCP ensures any organization is able to resolve any of the above crises. 16 The data related to the services or the goods that need to be delivered can be obtained through the mission statement of the organization. Moreover, the legal and delivering specifications of the products or the services can also be achieved via mission statement. The objective of the IT department states mission-critical functions and services for the organization. (this is my own constructed mission statement) 16 As the I.T department has not implemented a risk management and I.T service management framework, we were not able to find the required answers. (I have assumed these requirements, as there is no case study) 17 The additional expenses must be determined if the functions or procedures related to the business are untreatable. Moreover, this should also be taken into consideration that for the duration of time the functions can be operated without the hiring of additional staff. Similarly, the government regulations  regarding the fines, penalties, breaches must be determined and factored into the BCP budget. Risk management framework address risks that can be mitigated, transferred, void or accepted.

Different control sensors Essay Example for Free

Different control sensors Essay The idea of a pressure sensor is to ultimately measure and monitor the pressure of either gasses or liquids. But, what is pressure? Well, pressure ultimately is an expression used to describe the process of the force that is used when restraining a gas or a liquid from expanding. It has a certain measurement normally in the force per unit area. When the pressure is measured it can be monitored in a number of ways, but, most typically it is done with an electrical signal. We can see many examples of pressure monitors/switches in appliances all over the world today. Pressure sensors are found in items such as cars and lifts. For example, a person walks up to a door and they wish for it to be opened on arrival, with a pressure switch located in the floor as soon as the pressure switch is activated the door will open, this form of switch will tend to require a form of displacement. Another example if where a pressure switch/monitor may be found is within a car. When the tyres reach a certain pressure the control system kicks in and then they are warned to pump them up. If we consider large industries such as factories with combustion engines then we need to bear in mind that there needs to be some form of indication when present conditions change within the mechanism, this is also where a pressure sensor will come in handy. The picture on the top left of this paragraph is similar to what may be found in an industrial placement. A Rotary Switch A rotary switch is used when we have a devise that needs to operate or change to two or more different states, for example, a rotary switch may be used for; A fan that regulates heat at different speeds A radio that needs to operate on different frequencies The most common type of rotary switch is the rotary light switch, and the way in which this works is pretty straight forward. A rotary switch is a device that has a rotating shaft connected to one terminal capable of making or breaking a connection to one or more other terminals (the rotating shaft can be seen in the picture on the left) to many other types of electrical switching mechanisms, the electromechanical rotary switch provides a desirable means to control large numbers of circuits over a wide range of currents, voltages and power requirements. Rotary switches provide electrical control for the following types of equipment; Medical equipment, Aircraft, computers, Â  Industrial controls, Â  Communication, Â  Ordnance, Â  Ground support equipment Different types of rotary switches are used in a variety of electric devices. They are in the form of at least two parts and have a rotatable switching means arranged in a grouping and a rotary knob having a coupling element which can be pushed into or onto the switching means. The rotary switches are provided with a contact/sensor system and with a detent mechanism. The detent mechanism determines the number of possible switch positions. Rotary switches may feature different switch positions that can be set by rotating the switch spindle in one or another direction. Rotary switches may convert positions into binary numbers; such switches are known as coded switches. A rotary electromechanical encoder includes the overall characteristics of a rotary switch, but has additional mechanical movements. Pyrometers A pyrometer comes in very useful in industrial places where measuring and controlling inputs and outputs of a computer system become far too dangerous for a human to undertake the responsibility. It is often used to determine and control the temperature; however, it can also be used for radiation purposes. The word pyrometer is derives from the Greek word for fire, and the Greek word for measure, which is meter. As previously said, pyrometers are optical aids and although now days there are many forms of pyrometer as the need for more specific, demanding control systems are required the most basic still works on the principle below; On the previous page we can see how a basic optical pyrometer works, the only problem being that it can display temperatures that are high (up to around 700oC, but is inefficient for very low temperatures. As temperature inside the work place/furnace increases, so does the filament inside the pyrometer giving off a red colour, indicating the heat capacity. Using digital readouts the user can use the pyrometer to calculate the temperature of the material and also use the pyrometer to heat the material or furnace, or wherever the control system is placed to whatever they require. Thermocouples A thermocouple is a very simple heat/temperature sensor and comprises of two components. One end is joined tightly and the other end is separated. It is the end that is separated that is considered to be the output of the control system, and this is the end that actually generates the voltage. This voltage is then proportional to the heat or temperature to which it is measuring. This then means that the hotter the temperature the more voltage is output. Below can be seen the two most commonly found applications of thermocouples; Measuring room temperature Monitoring the presence of a pilot light It is the actual materials used within the control system that determines the application. There are then thermocouple types derived which can be used for differing purposes. Thermocouples are easy to use and require no batteries or fancy electronics. However, the voltage signals generated are very small so an amplifier may be required if you wish to read the temperatures into a computer Control System Thermometers Control system thermometers consist of a normal day to day thermometer thats connected to an electric circuit. Then, when the heat/temperature reaches a certain level it can be indicated or displayed in a number of ways, for example if connected correctly we could have it so that the temperature, when it hits 20, displays a red light located somewhere else, and, then when it falls below the light goes off. Inductosyn The idea of an inductosyn is to read the measurements of current within a system and then make extremely accurate measurements or movements based upon these readings. The principal in which it works is as follows. Incremental Absolute An inductosyn has a metal block in which grooves are cut out. Along these grooves are continuous strips of magnetic metal, then, a current is passed from one end to the other. The sliding block has an identical strip set in to it completes the circuit when connected with the other strip. Now we have the possibility of resistance change, by sliding the sliding block from one end to the other we have a system that changes the resistance of the circuit. This then increases and decreases the current accordingly. This is then output to a display which the user can see. This relationship between current and movement can then be used to move objects very small distances with a tremendously high degree of accuracy. This is all based on the current. Thermistor A thermistor is a type of resistor that varies resistance in a computer control system according to the temperature readings. Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in temperature. A temperature sensor application would be compared to that off the one found in a central heating system. A sensor would detect the temperature in the air, by using a thermometer and then change as desired using something like a thermistor. The thermistor would act as the thermostat. Therefore, when the thermostat is changed, we can change the output of the heating system accordingly. The thermistor is widely used and often unknown to the untrained eye. Linear Limit Switches The theory behind the linear limit switch is very straight forward. Basically the linear limit switch is a button, that when activated starts a process. In relation to computing its like an event drive operation. For the linear limit switch to be activated it must be pressed. For example, in a lift, how do we get the lift to stop going up, or, stop going down, or stop on the right floor. It would be of my opinion that a linear limit switch is implemented, so that when the lift reaches the required floor, a switch is activated and the lift stops and the doors open. However, its not limited to lifts, the linear switch is a very common device. In the picture on the left we can see a clear example of a linear limit switch. The operation needed to be performed is for that of the swimming pool cover, when the cover reaches the end of the pool the switch is pressed and the motor stops working, this then stops the problem of the cover falling off of the reel.

False position method and bisection

False position method and bisection In numerical analysis, the false position method or regula falsi method is a root-finding algorithm that combines features from the bisection method and the secant method. The method: The first two iterations of the false position method. The red curve shows the function f and the blue lines are the secants. Like the bisection method, the false position method starts with two points a0 and b0 such that f(a0) and f(b0) are of opposite signs, which implies by the intermediate value theorem that the function f has a root in the interval [a0, b0], assuming continuity of the function f. The method proceeds by producing a sequence of shrinking intervals [ak, bk] that all contain a root of f. At iteration number k, the number is computed. As explained below, ck is the root of the secant line through (ak, f(ak)) and (bk, f(bk)). If f(ak) and f(ck) have the same sign, then we set ak+1 = ck and bk+1 = bk, otherwise we set ak+1 = ak and bk+1 = ck. This process is repeated until the root is approximated sufficiently well. The above formula is also used in the secant method, but the secant method always retains the last two computed points, while the false position method retains two points which certainly bracket a root. On the other hand, the only difference between the false position method and the bisection method is that the latter uses ck = (ak + bk) / 2. Bisection method In mathematics, the bisection method is a root-finding algorithm which repeatedly bisects an interval then selects a subinterval in which a root must lie for further processing. It is a very simple and robust method, but it is also relatively slow. The method is applicable when we wish to solve the equation for the scalar variable x, where f is a continuous function. The bisection method requires two initial points a and b such that f(a) and f(b) have opposite signs. This is called a bracket of a root, for by the intermediate value theorem the continuous function f must have at least one root in the interval (a, b). The method now divides the interval in two by computing the midpoint c = (a+b) / 2 of the interval. Unless c is itself a rootwhich is very unlikely, but possiblethere are now two possibilities: either f(a) and f(c) have opposite signs and bracket a root, or f(c) and f(b) have opposite signs and bracket a root. We select the subinterval that is a bracket, and apply the same bisection step to it. In this way the interval that might contain a zero of f is reduced in width by 50% at each step. We continue until we have a bracket sufficiently small for our purposes. This is similar to the computer science Binary Search, where the range of possible solutions is halved each iteration. Explicitly, if f(a) f(c) Advantages and drawbacks of the bisection method Advantages of Bisection Method The bisection method is always convergent. Since the method brackets the root, the method is guaranteed to converge. As iterations are conducted, the interval gets halved. So one can guarantee the decrease in the error in the solution of the equation. Drawbacks of Bisection Method The convergence of bisection method is slow as it is simply based on halving the interval. If one of the initial guesses is closer to the root, it will take larger number of iterations to reach the root. If a function is such that it just touches the x-axis (Figure 3.8) such as it will be unable to find the lower guess, , and upper guess, , such that For functions where there is a singularity and it reverses sign at the singularity, bisection method may converge on the singularity (Figure 3.9). An example include and, are valid initial guesses which satisfy . However, the function is not continuous and the theorem that a root exists is also not applicable. Figure.3.8. Function has a single root at that cannot be bracketed. Figure.3.9. Function has no root but changes sign. Explanation Source code for False position method: Example code of False-position method C code was written for clarity instead of efficiency. It was designed to solve the same problem as solved by the Newtons method and secant method code: to find the positive number x where cos(x) = x3. This problem is transformed into a root-finding problem of the form f(x) = cos(x) x3 = 0. #include #include double f(double x) { return cos(x) x*x*x; } double FalsiMethod(double s, double t, double e, int m) { int n,side=0; double r,fr,fs = f(s),ft = f(t); for (n = 1; n { r = (fs*t ft*s) / (fs ft); if (fabs(t-s) fr = f(r); if (fr * ft > 0) { t = r; ft = fr; if (side==-1) fs /= 2; side = -1; } else if (fs * fr > 0) { s = r; fs = fr; if (side==+1) ft /= 2; side = +1; } else break; } return r; } int main(void) { printf(%0.15fn, FalsiMethod(0, 1, 5E-15, 100)); return 0; } After running this code, the final answer is approximately 0.865474033101614 Example 1 Consider finding the root of f(x) = x2 3.

Children are our future and they should be given every possible opportunity to succeed in life even if they are born into disadvantaged situations. Sometimes the families of certain children can’t provide as much as other children’s families and this can create a gap in the achievement and development of these children. Those disadvantaged children need special programing that accommodates for the lack of cognitive and social development that if not properly addressed could lead to poor school performance and delinquency. The Head Start program was created to address this shortcoming that some children face and to catch them up with their more advantaged peers. (Garces, 2002, p. 999) Head Start was originally designed to provide a nurturing environment that would provide children with preschool education, positive social interaction, and nutritious snacks and meals to help compensate for the lack of those things in the children’s lives. Head Start does an adequate job at meeting the needs of children in the manner in which it was originally founded. The Head Start program is not bad and should not be done away with. But, from what I have learned through this study, amendments could be made to increase the longevity of the desired results. In this paper I will discuss the Head Start program. How Head Start has succeeded. The way it attempts to influence children’s behaviors. I will also discuss some of the shortcomings of the Head Start program and ways to make the program more effective.

This investment would serve to better achieve a reduction in crime and delinquency. This upgrade would be relatively simple since the current policy is similar to the Perry Project. Another very important reminder, and something that I became aware of through this project, is to always consider the individuals who will be impacted by this policy. The investment in their lives is extremely important because at the ages that early intervention deals with, they may not have anyone else to fight for them.

Offreds Narrative - What is the purpose and function of the Historical

Offred's Narrative - What is the purpose and function of the Historical Notes and how do they assist your interpretation of the novel? The historical notes are not part of Offred’s narrative, they are a transcript of a symposium held at a university in 2195 – two hundred years from where we left the end of Offred’s harrowing tale. The purpose of these notes if any, is to put Offred’s narrative into a historical purpose to help these academics understand the life of Gilead. It seems to me that another purpose of these historical notes is to provoke a very strong reaction in the readers who have followed the emotional journey with the narrator Offred. The significance of the university name ‘Denay, Nunavit’ is that Atwood took the name from a group of people called Dene from Canada’s North west territories and they are about to become the first self-governing group of North American native people in an area called Nunavit. Atwood has chosen names such as Maryann Crescent Moon and Johnny Running Dog for the professors suggesting that the native Americans overbear the academy which strongly contrasts with the white male-dominated patriarchy in the Gilead times in this future world Atwood has made the white males become the vulnerable subjects of a study and nit the dominant rulers and scholars they once were. Also the name of the university sounds like the sentence ‘Deny None Of it’ suggesting that Offred’s story was all true despite what my be said or not said in the historical notes. The purpose of the lecturer that Atwood created Professor James Darcy Pieixto is to give readers a masculine view of Offred’s story which is ironic due to the domineering and powerful roles that the males played in Offre... ... see themselves progressive but hold the seeds of patriarchal oppression. With Pieixto’s appeal for some understanding feelings toward Gilead which was then followed by an applause this also suggests such moral ambivalence getting ready for such future evils. Another purpose for these notes is also to show how academics miss the point completely when looking at some historical facts and Atwood shows an example of this with these notes, how people can be sending out the wrong message and doing false teachings. The finishing sentence â€Å"Are there any questions?† gives the story a deliberate open-ended conclusion, here I think Atwood wants readers to discuss or at least think about the message she has just shown us, that the end of The Handmaids Tale is only the beginning of a discussion of the issues raised in the story, of what will our world finally become?

Drama in Act 1 Scene 5 and Act 3 Scene 1 of William Shakespeares Romeo

Drama in Act 1 Scene 5 and Act 3 Scene 1 of William Shakespeare's Romeo and Juliet 'Romeo and Juliet' is centred around three main themes. The love between Romeo and Juliet combined with the hatred between their families. 'Romeo and Juliet' is also about fate and destiny. In the prologue Romeo and Juliet are referred to as "a pair of star-crossed lovers". These themes are all closely linked and have consequences which eventually result in Romeo and Juliet's deaths. The chosen scenes are the most important in the play. The actions in these scenes create a lot of tension and are central to the plot. In the first scene Tybalt is given a reason to want to fight Romeo. Romeo and Juliet meet for the first time and instantly fall in love, only to be driven apart in the second scene when Romeo is banished as a consequence of a fight; this is immediately after they have secretly married. These scenes are closely linked, as the main action in act 3 scene 1 is a direct consequence of something which happened in act 1 scene 5.Shakespeare is a skilful dramatist. In the scenes he uses contrasting ways of gripping the audience's attention. Shakespeare uses a fast moving plot of only four days; he consciously shortened the source material to create effect. This makes it easier to act out as well as creating more drama. It shows how passionate Romeo and Juliet are. The shortened plot grips the audience's attention as there is always something of interest happening. The audience are shocked at how quickly things happen; there is always suspense as to what will happen next. Shakespeare has given thought to the position of act 1 scene 5; he c... ...acle and creates dramatic irony. This helps the audience feel involved as they have information the characters don't and it creates suspense as we wait for the characters to find out what we already know. Shakespeare creates tension and suspense throughout the whole play. This means we are constantly gripped and there is always something happening. This is helped by the fast moving plot which Shakespeare conscientiously created. Tension and suspense is a key aspect to the two key scenes and I think Shakespeare creates a lot of it and in an effective way. Shakespeare also very cleverly bases the two pivotal scenes around opposing themes which is dramatic in its own form. Overall I feel Shakespeare is a very skilful dramatist and knows how to grip the audiences' attention using a variety of techniques, in different ways.

Analytical and Empirical Method

How to conduct heuristic evaluation? 5 Advantages5 Disadvantages6 Empirical Method (Usability Testing)7 What is Usability Testing? 7 How to conduct a usability testing? 7 Advantages of Usability Testing8 Disadvantages of Usability Testing9 Conclusion10 Task 211 Introduction11 Description of the problem11 Description of the difficulties11 Conclusion:14 References:15 Task 1 Introduction There are 4 ways mostly to evaluate user interface.Heuristic Evaluation (heuristically) by just looking at the interface and passing judgement according to one’s own view. Cognitive Walkthrough (analytical method) by some analysis procedure, Pluralistic Walkthroughs (empirically) by experiments with trial users, Feature, Consistency & Standards Inspection (automatically),by a programmed procedure. For this assignment I have choose the usability testing for empirical method where else for analytical method I have choose heuristic method. [1] Analytical Method (Heuristic usability) What is heur istic? Heuristic evaluation is a discount usability engineering method for quick, cheap, and easy evaluation of a user interface design. † [3] In heuristic evaluation the usability issues covered are effectiveness and efficiency but do not considered the satisfaction. Quantitative Data is not collected. this method also can be conducted remotely also can be used on any system. Several evaluators independently evaluate the interface & come up with potential usability problems. It is important that there be several of these evaluators and that the evaluations be done independently.Nielsen's experience indicates that around 5 evaluators usually results in about 75% of the overall usability problems being discovered. Heuristic Usability Principals Here I am going to explain more and have a closer look at what condition are needed to evaluate interfaces. Basically the evaluation is easier than design. The principles are the basic points that drive design and drive evaluation as well. The principals are: 1. Visibility of system status The application should always keep user on track and well known on which section of the application they are.This can avoid confusion and user can get the information easily without consuming more time. 2. Match between system and the real world. The relationship between two things, in most cases the mapping from digital world to real world. Metaphors and analogies 3. User control and freedom User should be informed what the system is doing and is the user on the right track, does it work the way it is suppose to work. This can prevent the user to do their activity correctly on path without having to redo all again. The application also should support undo and redo.The system should confirm with the user before take any action on the application, so user can exit immediately from new actions that risk them. 4. Consistency and standards An application should have a standard platform convention like the symmetry of the interfac e. Is it symmetrical? (Left-Right, Top-Bottom, Center). This includes also the wording to access the application example for navigation bar. The â€Å"Home† button should be same for all pages. It should not been changed to other type of looks (symbol or font) at other page when user access to it. 5.Error prevention The text message for error prevention should convey a message to user while they are currently on the application and risky to faulty. User can understand what the error message is about and prevent the faulty happen before they proceed to the next step. 6. Recognition rather than recall Using symbols that make user feel ease to recognize, remember and think what is the use of the button. The colour contrast also effect attention and focus where the user has been explored on the application. It also is to make user more focus and remember what they did.User also might convey the color for pink †¦ it’s a girl and blue †¦ it’s a boy. This wou ld not affect user memory load. 7. Flexibility and efficiency of use This refers to the perceived and actual properties of the â€Å"thing† that determine just how the â€Å"thing† could be used for new user that never been using that application. The appearance of the â€Å"thing† tells them how to use it. If the system is understandable, neither expert nor inexperienced can easily use the application. 8. Aesthetic and minimalist design The application should display the important and description for the point it is focusing on.The application should not display unnecessary information which will only cause the information traffic on the application. A special consideration for standards graphics and design are enough to make user comfortable when using the application. 9. Help users recognize, diagnose, and recover from errors The error text must not be too long or too short. It should be simple and precisely organized to make sure the user understand the faul ty they have done and they can correct the error based on the solution given in the error message. 10. Help and documentationThere might be possibilities that user don’t need any help and documentation while or after using an application, but there is the chances for user to document the information and get the help if there are lost. This should be considered to ensure user get fully access and satisfied after exit the application. The application must make the user easy to find the information they are looking for focusing on their task and help should provide the step they should pursue. How to conduct heuristic evaluation? Heuristic evaluation by Nielson is a method used by researchers to find usability problems in interfaces designed for use by public.The heuristic evaluation process starts from questions a small number of users, called evaluators, to complete a set of pre-programmed tasks usually related with using the interface. As summary basically the evaluation will be : * Obtain the service of 4, 5 or 6 usability experts, questions a set of pre-programmed tasks usually related with using the interface. * Each expert will perform an independent evaluation, answer question related to interface * Give experts a heuristics inspection guide, is followed from Nielsen’s ten usability principles (Nielsen, Jakob 1994). Collect the individual evaluations, which are answered in subsequent iterative sketch of the interface for better simplicity of use and significant knowledge.* Bring the experts together and do a group heuristic evaluation. (Optional) Advantages Quick and relatively inexpensive feedback to designers can be provided by this method. Response can be obtained early in the design process. Conveying the correct heuristic can help suggest the best corrective measures to designers. * Cheaper comparative to other assessment method. * Spontaneous and simple to encourage potential evaluators to use the method * No advance planning required Formal usability training is not required for evaluators. Professional computer programmers and computer science students are used in Nielsen and Molich * Can be used early in the growth process * Quicker revolve time than laboratory testing Disadvantages Applying heuristics effectively need a good knowledge and skill. Usability experts sometime hard to find and can be pricey. Multiple evaluators are recommended and results must be aggregated. Minor issues and fewer major issues can be detected through these evaluations. * Evaluators maybe just have the understanding of usability design principles, but not for usability experts.Usability experts would recognize more issues than non-experts, experts are the people who have the skill with the type of interface being evaluated, they can identified the most issues was according to Nielson. * The results from multiple evaluators must be aggregated. This is because the evaluator only can detect few issues, but if the issues combined the m ore precise result outcome they can gain. * Heuristic evaluations only identify lesser usability issues compare to and other discount methods may not identify as many usability issues as other usability engineering methods, for example, usability testing. Complex interfaces may not scale well for heuristic reviews. Evaluators may not find the major or serious problem the interface had if the interfaces are complex. * All the issues identified may not willingly suggest solutions for the usability issues * The evaluators are just pretend to be the user but they are not the real user. * The entire problem identified may not be the actual problem in real interface. Empirical Method (Usability Testing) What is Usability Testing? We need to use usability testing method to produce tasks professionally, efficiently and pleasingly for the user benefit.It is better to produce a pre-programme application to ensure so that any important issues can identify. Usability testing can be done at any stages of the design process. Usability testing is not an alternative for a human centred design process and appropriate techniques such as walkthroughs also can be use. Test host or the user who is going to represent for usability testing session should attend. The attendance should be at least one observer one developer and one business representative. Observers should strictly be in a separate observation room.Density of the system, the number of intended users, and budgetary constraints should be considered when doing the session. Even one test session is better than none, but if its more it will tend to discover the majority of important issues. There are two major factor should be considered when conducting a usability testing. The first is to ensure that the best possible method for testing is used. The second major consideration is to ensure that an iterative approach is used. How to conduct a usability testing? To prepare for a usability test we must identify delegate tasks .Ideally, these should derive from scenarios or use cases developed earlier in the design process. Have a clear definition of when a task is complete. We also must prepare a test schedule, book the required room, and identify representative users and invite them to attend. We will need the following materials: †¢ A formal script so that all participants are treated in the same way. †¢ A pre-evaluation questionnaire to check that your participants match the required profile. †¢ A list of tasks, together with criteria for measuring whether they have been successfully completed. Logging sheets to record timing, events, participant actions, concerns and comments. The guidelines should be followed: †¢ Run a pilot test. †¢ Ensure that participants have the option to abandon any tasks which they are unable to complete. †¢ Do not prompt participants unless it is clearly necessary to do so. †¢ Record events in as much detail as possible to the level of keys trokes and mouse clicks if necessary. †¢ If there are observers, ensure that they do not interrupt in any way. Observers formally prior to test. †¢ Be sensitive to the fact that developers may be upset by what they observe or what you report.Advantages of Usability Testing The advantages of usability testing are [5]: * Reply direct from the board audience to spot the project group * Private conversation can be done by testing the issue to see how users response to the different options being discussed * Problem and possible difficulties are stated clearly before the product is launched. The business advantages of usability testing can be seen at the end of the project: * Probability of usage and frequent usage increase * Risk of the product fault is reduce * Users are able to get what they expect, which makes business meeting its targets achievable.Benefits of using usability testing are [6]: * Reduce maintenance costs, increase user fulfilment, and save on development eff ort cost. * Relevance feedback helps to increase the quality experience. * Measures activities, not preference. Users like to insist what they want, but by observing and measuring behaviour, we can understand what the best for their needs and support is. * Get a competitive benefit. User with no experience can give negative impact to a website. A systematic website is expected by users, especially when the competitors of websites developer are a lot now. Focus to the major needs and the aim of the application. Disadvantages of Usability Testing Usability testing provides many benefits, but there are the disadvantages in using this methodology, which should be noted. Firstly, testing is not 100% representative of the real life scenario. Also, usability testing is mainly qualitative, so does not provide the large samples of response that a questionnaire may, but the response can be far more precise and understandable. It requires a certain level of knowledge and experience to apply th e heuristics effectively. Trained usability experts are sometimes hard to find and can be expensive.Multiple evaluators are recommended and results must be aggregated. The evaluation may identify more minor issues and fewer major issues. [9] Conclusion Two common usability evaluation methods, heuristic evaluation and usability testing were analayse. Results found that heuristic evaluation performed by HCI experts revealed more general problems, while usability testing is a way to see how easy to use something is by testing it with real users. To provide the most effective and thorough usability evaluation results, a combination of usability evaluation techniques from both expert and system user perspectives is recommended. Task 2Introduction For task 2, I am going to evaluate a website from a bank which is OCBC bank. Description of the problem 1. The first problem i notice when I start to evaluate the website was the layout. the layout is merely merge to left side of the webpage. 2. The navigation bar size. It is too small. 3. The application do not provide â€Å"search† function for user to search information. 4. I didnt notice the login function,no idea where to login. The homepage there is no official login space. 5. No language selection option. 6. No register new user and login specific space at main page. 7. No sitemap to track location in application page. . The process option button and link appearance are not interesting and recognizable. 9. Once the user click any options from main page to proceed the next step,the application open new window.

Summary A heuristic evaluation is a usability inspection helps to identify usability problems in the user interface (UI) design, As I find in the OCBC Bank website, it specifically involves me examine the interface and judge its compliance with recognized usability principles (the â€Å"heuristics†).I independently examine a user interface and judge its compliance with a set of usability principles. The result of this analysis is a list of potential usability issues or problems. The usability principles, also referred to as usability heuristics, are taken from published lists. Ideally, each potential usability problem is assigned to one or more heuristics to help facilitate fixing the problem. As more ev aluators are involved, more true problems are found.But as from my view, I can list out only these usability problems and I also have stated the reasons and why it is a problem to me and also what is lacking at the webpage.

Melancholy in Twelfth Night

Twelfth Night is the merriest of Shakespeare’s romantic comedies, it is also the saddest. The Christian associations of the title suggests the carpe diem theme which runs through the play. Epiphany, according to Christian mythology, is the time when the shepherds recognized the birth of Christ. The feast of epiphany is the last festival of the Christmas season, after which death takes over. This cycle of life is an extension of the ancient pagan fertility rituals. The mood is similar in Keats’s ‘To Autumn’, Hedge-crickets sing; and now with a treble soft The red-breast whistles from a garden-croft;And gathering swallows twitter in the skies. Only, Keats finds reassurance in the fact that swallows will return, but Shakespeare is concerned with the cessation of life which looms over the whole play. Here the recognition is of the transience of life, unlike in Cymbeline where the rediscovery of Perdita symbolises the rediscovery of one’s soul. Significan tly, Twelfth Night is the last of the romantic comedies. After this Shakespeare moves on to the tragedies and the problem plays – this is the last play where joy is not alloyed with problems of evil and anti-life.Everything that is subject to time is valueless, this was the medieval conception. Thus during the middle ages all human activity was directed towards God. Man was given little importance. Then with Renaissance came yet undiscovered knowledge. The new astronomical discoveries allowed man to explore the universe independent of the scriptures. With this was born man’s pride in being man in the mortal universe. And thus man became conscious of the beauty and transience of life. This removed the concept of life everlasting from the framework of eternity.This introduced the prominence of mortality. The dance of death was now more feared than ever. New questions about human existence took form. Comedy seeks to find answers, a meaning of life; yet Shakespeare present s a frail shadowy background to his actions. One of the main governing thoughts in Twelfth Night is the fragility of life. This is the play of youth, almost all the characters are young, and this generates the sadness. Shakespeare asks all to enjoy fleeting life, make the most of the twelve days, scorning the Malvolios.A pattern emerges from all this lot which gives life some meaning. Twelfth Night, despite all its laughter, seems to play upon the keys of loss, affliction and deep bewilderment, which sounds through the gentle beauty of the romance convention and the festive humour. The bonded family words – father, brother, sister – signifies absence, loss of security and a longing. It is this sense of irreparable loss, and the mild apprehension that all this might prove to be a dream provides the poignant dream-like feeling which pervades the play.The loss is internal as well as external. The recognition of one’s self is a dominant theme, and almost all charact ers are haunted by this and hunt for their selves as well as their lost loves. Orsino’s languorously insatiable desire for love and ‘food of love’ in the first scene presents a parodic statement of the omnipresent sense of want. The hunting pun serves to express the search which is already begun. Nevertheless, Orsino’s words set the mood of the play, which, even through all the ‘caterwauling’ of the kitchen group, never fades. Orsino saysThat strain again, it had a dying fall: O, it came o'er my ear like the sweet sound That breathes upon a bank of violets, Stealing and giving odour Orsino’s appetite is soon satiated. The music loses its appeal and his love for love becomes evident. Even the hunting image takes on contemporary significance – Diana becomes the naked truth which makes Acteon wild. This is a parody of Petrarchan conceits and it is fittingly given to Orsino, who, like all in Illyria, is in a state of illusion. Accord ing to Plato’s Symposium love is a hole, an absence longing to be filled.So Twelfth Night is a play of pining: Orsino for Olivia, Olivia for Viola, Viola for Orsino, and comically Sir Andrew and Malvolio for Olivia. This emphasis on pining invokes the classical myth of Narcissus and Echo, and makes a narcissistic triad of self enclosed loneliness. Each of them playing simultaneously Narcissus and Echo with respect to others. They seek their own reflections in the other’s face and own echo in the other’s voice. But more melancholy than this ‘love-sorrow’ is the separation of loved ones by real or apparent death. This again can be traced to the sense of romantic lack as embodied in this state of primary loss.Nearly all characters bear traces of such loss – from the father-brother loss which provides similar traumatic experiences for Viola and Olivia, down to the farcical yet nostalgic exclamation of Sir Andrew: ‘I was adored once, too. â €™ While Viola’s sorrow is genuine, Olivia’s vow to keep her face veiled for seven years seems more like a ploy to ward off Orsino’s unwanted advances. Otherwise her whole behaviour is comically excessive in place of being melancholy. Seven years in black violates the Elizabethan mourning etiquette which prescribed a period of one year for a brother.Olivia closely parallels Orsino – both in her reclusiveness more alleged than borne out – and as a willing victim of introspective melancholia. Olivia’s unnamed brother fades from the surface of the play. But his spirit continues to haunt. For no sooner has the theme of brother loss been sounded in the minor key than it recurs in the major. The ‘eye-offending brine’ of tears gives way to the sea. Olivia’s brother fades into Viola’s. In a drama greatly concerned with wholeness of identity, the twinned heroines are each presented as halves of a pairing, cloven away fr om the male counterpart with whom she started life.In Jungian terms, when Viola assumes the male disguise, it is as if she recapitulates in her own person the lost other, dressing exactly like Sebastian, and as if Olivia also locates her own in Viola. Herein lies the fact that both of them are in an illusory world, it is only the presence of Sebastian which allows a happy resolution, otherwise the imminent result was definitely tragic. There might be an autobiographical element in this brother-sister separation theme. Shakespeare himself was the father of boy-girl twins of whom the boy died before the composition of this play.The twins were eleven and half years old when death separated them. Shakespeare must have felt at heart the wistful sadness in the eyes of Judith the surviving child, which he endowed to viola. Twelfth Night contains a calm, loving elegy, and a myth of rebirth. It feigns that Hamnet, the boy twin, is not dead, but lingers in the unknown, washed up on the shores of Illyria, the land of illusion and lyricism. Prove true, imagination, O prove true This is not only Viola’s, but also Shakespeare’s heartfelt cry. Thus Viola’s sadness resounds with a new meaning. Her exclamation at her entry is,And what should I do in Illyria? My brother he is in Elysium. Her brother comes back to her, but Hamnet does not. Unlike Sebastian, Viola controls herself and centres her thoughts on immediate problems. Her wit allows her to obtain a shelter in an alien and unfriendly world. But her wit also has a touch of the autumnal – in keeping with the autumnal note of the play. And even in her sorrow she can sympathise with others. She understands Olivia’s plots instantly in place of scorn, shows tender understanding, she says, Alas, our frailty is the cause, not we, For such as we are made of, such we be.Her identification with Olivia is appropriate in more ways than one – not only both of them are lovesick, but also they l ong for a brother figure. But Viola’s pathos is more touching. She has to bear messages to her rival from the man she loves. This she does without a murmur and with all sincerity. Her praise of Orsino comes straight from her heart. She is pained to the extreme, and almost reveals herself when Orsino calls women less faithful and lacking in depth of emotion. She tells the Duke: My father had a daughter lov’d a man, As it might be perhaps, were I a woman, I should your lordship.Thus secretly professing her love. But her suppressed agony is felt when she tells Orsino the supposed ending of her non-existent sister’s love whose history was, she tells Orsino, A blank, my lord: she never told her love For she never expects to have Orsino and she dares not aspire to the impossible. As when her brother’s name is mentioned she fears to hope for the best. Shakespeare saves the play from ending in total disaster by bringing in Sebastian and thus allowing Viola to hav e a happy end, in an union with Orsino. In the first scene orsino begins with an imagery of flowers.And the scene ends with flowers: Away before me to sweet beds of flowers! Love-thoughts lie rich when canopied with bowers. The image of flowers comes again and again throughout the play. Flowers symbolise transience – momentary beauty, something that does not last. So Feste tells Olivia: As there is no true cuckold but calamity, so beauty’s a flower. Reminding her that times are never always bad, thus to keep on mourning for something that is past is to waste precious time and no one has world enough and time. Orsino talks about woman’s beauty, asking Cesario to fall in love with some woman younger than he,For women are as roses, whose fair flower Being once display'd, doth fall that very hour. Viola has to agree. She admits that death comes when one has just reached perfection. Speaking not only for women but for all mankind. The flower imagery stresses the carp e-diem theme of the play – cease the day before it ends. This theme is also propagated through the music of the play. In Twelfth Night music plays a vital role, establishing the tone of the play. Through music the emotive basis of human existence is emphasised, which is to be felt rather than perceived cerebrally.There is rare music in Viola. She does not sing, but her words carry poetic inspiration. She echoes Shakespeare’s sonnets when she tells Olivia: Lady, you are the cruell'st she alive If you will lead these graces to the grave And leave the world no copy. Like the early marriage sonnets the theme here is of beauty perpetuated through marriage. But the character who is full of music and is truly melancholy, though not in his attitude or expression, is Feste. Feste is the first true fool of Shakespeare's plays. One of the functions of the clown is to sing. He sings to Toby and Andrew:What is love? ‘Tis not hereafter, Present mirth hath present laughter: Wha ts to come is still unsure. In delay there lies no plenty, Then come kiss me sweet and twenty: Youth’s a stuff will not endure. The fragility of youth and shadow of death – this is in line with the play’s theme and mood and also Feste’s character. His other song, which he sings to please Orsino, is equally sad, Come away, come away death, And in sad cypress let me be laid. Fie away, fie away breath, I am slain by a fair cruel maid. This song continues to reveal Feste’s own bleak future.He is outside the action, an objective onlooker. There is no involvement. He is poor, has no security. He begs to acquire money. For a man of his intellectual capacities this must be disgusting. He has no past, no future and no considerable present. He is a relic of the past, from Olivia’s father’s time. He is constantly threatened with discharge which is as bad as hanging for him. But he lets summer bear it out. Only his song betray his state. Thus in his songs the thought of hereafter is subordinated. In the final scene everyone leaves except Feste, who stays to give the audience a song.A song in which he is transformed from the character to the actor. His final song marks the ending of the play, the ending of the twelfth night. Death’s reign starts from the next day. Feste’s song is nostalgic, he recalls when folly was not as unacceptable or threatening. He also gives a cynical view of marriage as an unwanted responsibility. This casts an oblique perspective on the centrality of marriage in the play as a symbol of concord and resolution. A great while ago the world begun, With hey, ho, the wind and the rain, But that's all one, our play is done, And we'll strive to please you everyday. That’s all one’ signifies from one perspective that since nothing is really important enough to worry about, pleasure and folly are the only activities worth undertaking. From another, similar, perspective the phrase c an be read as hopeless, despairing resignation, pleasure and folly are doomed attempts to escape from an intolerable consciousness of futility. In ‘our play is done’, it is more about the innocent activities than about the play itself. It is a nostalgic recognition of the post innocence state. Feste’s song probably takes place on a dark, empty, silent stage, encapsulating Feste’s loneliness.His life is really as empty. He is as much an outcast as Malvolio, only he is not embittered. He is the artist. Isolated, presenting life, but not belonging to it. His song is a very cynical comment on human existence. To Feste the world does seem like †¦ a tale Told by an idiot, full of sound and fury, Signifying nothing. The song is a reminder of the theme of the play – youth and its subjection to time. The question which arises is whether this kind of existence is worth the strife. With this question the curtain descends on Shakespeare’s romantic w orld.The final song, which brings together all the melancholy passages in the play, leaves a yearning in the reader’s mind. A tinge of sadness which fills the heart and leaves a deep impression, is given to the whole play. This song marks a turning point in the world of Shakespearean drama. The playful attitude is done, now it is time for serious businesses of life, which involves the greatest of calamities. Perhaps at the moment Shakespeare himself identified with Feste. He who even with his immeasurable height of mind had to be the public’s jester and servant. Perhaps for an idle moment he wondered, if all this is worth the complications or not.

Benefits Of Multinational Corporations Essay

Like any other multinational corporation, Acme Motors have been coupled with various economic implications and benefits to the foreign countries in which it operates. Acme is a motor vehicle company headquartered in Nuevo Laredo but performing other international business in Mexico, Spain and other countries. In the foreign countries, it has been involved in the manufacturing of motor vehicle engines above their assembly to complete vehicles. The performance of the company is usually fed by a number of comparative advantages which are implied by its operational capacity. Generally, the large scale capacity of the company has been a major advantage which the company uses to create economics of scale in its operational system through its broad endowed portfolio of technology. It has been able to successfully compete in the foreign international market which is highly competitive. The company has various artistic and management tools that help to impair the effects of foreign business culture which may lead to operational failures. It has a wide management support which compound the tools of research into the broad market and political risks operating in the foreign market which may bring operational losses. Either it has also used the tools of mergers and acquisitions to help prevent the negative impacts of foreign market infestations. (Skene, 1992) However, the operational portfolio of the company has been faced by the challenges of negative externalities of environmental pollution and degradation in the host countries. Basically, the industrial nature of the company compounds various environmental degrading facets which include resource over exploitation emission to the air pollution, water pollution and the general socio-economic implications which are of negative external capacity. However, the problem of environmental pollution and degradation to the company allies to been a fatal problem which has even called for various statutory control programs both by the company and the state government. Usually the tool of increasing taxation has been a subjective implication which has helped the company to change its industrial characteristics. Through higher cost levies by such foreign governments, the company has changed its industrial technology to more environmental friendly methods which cause less pollution. Generally, through such taxes, the government has then compensated the society for such environmental pollutions above supplying various public goods which benefit the people. (Wray, 1997) To the company, the tools for control of environmental degradation have posited various cost implications both in the short run and in the long run. Since the system for implementing environmental control has been achieved through change in modifying operation to capture more friendly methods, this has however been costly. Higher cost has had a negative implication to increases in the cost in the short run. However, increases in cost have been ransomed through the use of proper management tools which ensure a well balanced business management conceptions which continue to provide the company competitively advantages in the market. However, the long run cost has been reduced through higher sells achievements from the active product support from the environmental friendly consumers. (Snowdon, Vane, 1997) Generally, as an important tool, the environmental aspect is an important tool which the company and any other should apply in the international portfolio. The cost of environmental degradation is costly and would perhaps outweigh the benefit cost relationship which provides grounds for competitive advantage at the market. Either, it is important in safeguarding the broad interest of the society with which the manufacturing (industrial) activity is allied to.

(Campbell & White, 2003). The intervention or indicator or the area of interest (I) will be in managing the effects of diabetes since diabetes is a chronic lifestyle disease and hence incurable and progressive. There is a need to check first if it is Type I or Type II so the proper interventions can be implemented. If the type of diabetes is now known, then the medication can be tailor-fitted to the patient in his particular case, depending on the circumstances that triggered his diabetes in the first place since there are risk factors to the onset of diabetes. The question is: â€Å"If it is Type I, then is it juvenile diabetes (affecting around 5% of the general population) as diagnosed among children and young adults† (American Diabetes Association, 2014). The key will be to adopt a twin approach to the management of this type of diabetes using hormone therapy (injectable insulin) together with the changes in diet (avoidance of sugary foods and drinks) and increased physical activities together wit h constant monitoring of possible hyperglycemia (high blood glucose) or probable low blood glucose (hypoglycemia) as an adverse reaction to the insulin hormone treatment or therapy. For the purpose of comparison and control (C) the diabetic patients are divided into their type of diabetes and then subdivided again into smaller groups based on their knowledge of diabetes (if the patients know what type of diabetes they have and what the treatments are there). While the general knowledge is that diabetes is caused by too much sugar, there is little literacy among diabetic patients on what interventions are available for them, how to avoid certain foods to prevent worsening the effects of

Mgt - Assignment Example Shaving heads is also a form of removing any vestiges of individuality from any of the people so that they are all reduced to defining themselves as their captors do (Zimbardo). The push-ups became an aversive form of punishment because the guards could demand that the prisoners perform even more of them when they felt like it. Push-ups are a form of exercise that is associated with students. It emphasizes the superiority of the ‘coach’ or empowered individual who demands that others partake in it. The guards used push-ups to victimize the prisoners and increase their feelings of helplessness. I do not believe that I would have been able to reject any privileges offered to me in order to maintain prisoner solidarity. It is evident that withdrawing into one’s self in order to find ways of surviving the brutal experience is something that prisoners are constantly thinking about. 5. Most prisoners believed that the subjects selected to be guards were chosen because they were bigger than those who were made prisoners, but actually, there was no difference in the average height of the two groups. What do you think caused this misperception? I believe that the hardships they were being forced to suffer at the hands of the said guards were elevating the status of the guards, as well as their physical capacities, in the prisoners’ estimation. The visitors, most of whom, shockingly, were parents of the incarcerated men, believed what the researchers in the role of guards and wardens informed them about their own sons even when they could see that their sons were not well. Even though the visitors were aware that this was a research study and not a real prison, they still placed more trust in the words of the wardens than what their own eyes were showing them (Zimbardo). Civilians are trained to trust the police, as well as prison wardens in real
