Corporate law - Case Study Example The exception to this is that the reserve may be applied by the company in paying up its unissued shares which are to be allotted to company members as fully paid bonus shares. Further, if the permissible capital payment exceeds the nominal amount of the shares redeemed or purchased, the amount of any capital redemption reserve, share premium account or fully paid share capital of the company, and any amount representing unrealised profits of the company for the time being standing to the credit of any revaluation reserve, may be reduced by a sum not exceeding, or by sums not in the aggregate exceeding, the amount by which the permissible capital payment exceeds the nominal value of the shares.4 Where, however, the proceeds of a fresh issue are applied by a company in making any redemption or purchase of its own shares in addition to a payment from its capital under these provisions, the references to the permissible capital payment are to be read as referring to the total amount of that payment and those proceeds. The CRR is mainly used to ens... The CRR is mainly used to ensure that the company's capital is not reduced by the redemption of its shares. If the company was to redeem its shares, and the CRR was not used, then there would be a reduction in the company's capital in line with the reduction of the amount of shares redeemed. Although the CRR cannot be distributed out to shareholders by way of dividend in the same way that profits would be utilised, they would be available for issuing bonus issues of share capital should such a scenario arise. Accordingly, the CRR plays an important role in maintaining the value of the company, by both keeping shareholders of redeemable preference shares happy in allowing them to redeem their shares, while also keeping the other shareholders content as the value of the share capital in the company is maintained. This means that there shareholding will be in no way diminished as a result of the redemption. Revaluation Reserves Revaluation reserves arise when the value of an asset becomes greater than the value at which it was previously carried on the balance sheet, increasing shareholders funds.5 Not every increase in value is added to the revaluation reserve, and the exact treatment depends on the history of the asset. Revaluations are carried out when there is a material difference between the current market value of an asset and the value at which it is carried on the balance sheet. Revaluation reserves are not distributable, but may be used for scrip issues, where there is an issue of new shares to existing shareholders at no charge, pro rata to their existing shareholdings. A scrip issue is essentially when one shareholder moves their money from one account to another account belonging to the

Employment-At-Will Case Essay Example for Free

Employment-At-Will Case Essay Case Example A: Elaine has sued Jerry because Jerry fired her. Elaine was on the job for two months.The job offer letter that Jerry had sent her mentioned the great career opportunities at the company and stated that her annual salary would be $30,000. The company is an employment†at†will employer. Elaine was given no reason for the termination. After the termination, Jerry hired a man named Kramer, who had less job experience and education than Elaine, for the position. Elaine has sued to get her job back. There are legal issues in case example A. These issues will need to be brought up and answered before any decision can be made over this case. A letter was sent to Elaine. Could this be considered a contract? If not, was there a contract involved? If there was a contract involved, is it an executory contract or is it not valid at all? This is an employment-at-will employer, does the employer really need to give a reason for the termination? Ethics in business play a big role in today’s society. Could ethics have been violated by the employer? Is this discrimination against Elaine? Did the employer lower Elaine in to this business with lies to gain something from her? Is this an intentional misrepresentation or fraud? Did Elaine have a certain skill that the employer needed and after the employer got what he needed he fired her? These are short legal questions that will need to be further studied. Elaine’s argument contains legal rules to support her claim. There is printed evidence that can definitely help out Elaine. The job offer letter states that there are great CAREER opportunities at the company. A career is defined as more than a simple job. It is a major part of a person’s life. A job usually last a couple of months. A career is thought of lasting for more than a couple of years. The fact that the term â€Å"career† was used in the letter, it is assumed that this is going to be something more than just a â€Å"job† Another word that was used is annual. The annual salary was said to be $30,000. The term â€Å"annual† also implies that the career that the employer is offering is something that is  long term and not just a two month job. The plaintiff can argue that these were the conditions that were used when she was hired. She sought out this job because she was offered great career opportunities but was never given the â€Å"career† or the opportunity to make $30,000 annually. This could be classified under intentional misrepresentation or fraud because the plaintiff was brought into the business with false statements. Something else that Elaine can argue is that she was discriminated. After she was fired, she was replaced by a man that had less job experience and a lower education than Elaine. Elaine might have been let go because of her sex. This could be a violation of Title VII of the Civil Rights Act of 1964. The defendant also has a valid argument that he can dispute. This business is an employment at will employer. This means that the employee can be let go at any time for any reason. Elaine knew that this was an employment at will. When she read the letter and accepted the job, she also accepted all the conditions that came along with it. The plaintiff knew that she could be fired any time. This is the defendant’s argument. Based on facts and legal laws, the judge can look over the evidence and rules and make a decision. The employment-at-will doctrine clearly states that the employer can fire the employee at any time for any reason. There are many exceptions to the employment-at-will doctrine. In this case, the tort exception and statutory exception can be applied in favor of the plaintiff. The tort exception states that the employee can sue an employer for fraud. Based on the letter Elaine received, she never was given what she was promised. The employer gave the future employee false statements regarding receiving $30,000 annually. The employer also made the employee believe that this was a career when it clearly lasted no more than two months. This is classified under fraud. The statutory exception will be the main exception in this case. The statutory exception states that â€Å"Title VII and other federal state antidiscrimination laws prohibit employers from engaging in race, sex, religious, age, handicap, or other forms of discrimination†. Right after Elaine was fired, a man was hired for that same position with less work experience and a lower education. This is evidence that Elaine was discriminated based on her sex. An employee who was wrongfully discharged can sue the employer for damages. Therefore the plaintiff will win the case. The legal rules that currently apply are fair and reasonable.  Employment-at-will employers exist because in some jobs, the employer needs that flexibility in order to respond to any changes or needs. Sometimes it is necessary to let employees go but the employer should never forget the laws of business and also ethics. Also, adding exceptions like statutory exception and tort exception to this doctrine helps protect employees in case they are ever treated unfair or are ever taken advantage by their employer. The rules that are currently set for now are fair and reasonable and should not be violated. Work Cited Cheeseman, H. R. The legal environment of business and online commerce. (Custom ed.).

Revenge and Vengeance in Shakespeares Hamlet - Family Honor :: The Tragedy of Hamlet Essays

Hamlet: Vengeance and Family Honor In the play of Hamlet the main theme is the theme of vengeance and the need of the characters to protect their family's honor. This does not only have to do with Hamlet himself but is also illustrated in two other important characters of the play, Laertes and Fortinbras. All three of these characters are faced with the problem of having to avenge their nemesis who had previously hurt their family or their family's name. The idea of vengeance for the sake of family honor causes great destruction throughout the play and causes many more people get caught up in this circle of destruction and vengeance. From the very beginning of the play the reader notices the first signs of the hate and the need of vengeance from some of the characters. Initially the Norwegian prince Fortinbras is shown getting ready for a voyage to conquer Denmark. His huge ambitions as we find out later are driven solely out of hate toward the old Danish King Hamlet (Hamlet's father) who had previously defeated Fortinbras' father in battle and took some of Norway's territory when Fortinbras was still a child. As a result, young Fortinbras aspires to recover the lands and power lost by his father as a way of honoring and avenging him. Then as the reader goes on further and deeper into the play, the feelings of hate and vengeance also take over the mind of Hamlet. After talking to his father's Ghost, and then staging the play Hamlet is almost totally sure that his uncle King Claudius had killed his father in order to take the power of the throne of Denmark. But unlike Fortinbras, Hamlet does not act quickly and is paralyzed by his own indecision and fear. This paralyzation or the inability for Hamlet to act and take vengeance could be described as being his main problem. "According to the view which was originated by Goethe and is still the prevailing one today, Hamlet represents the type of man whose power of direct action is paralyzed by an excessive development of his intellect." (Sigmund Freud) The climax occurs when Hamlet finally takes revenge, but unlike it is for Fortinbras, Hamlet's revenge comes with great cost to all. His previous inability to act and take revenge sooner cause, ironically, the death of b oth his mother (who drank the poison destined for Hamlet) and the woman he loved Ophelia (who most likely committed suicide because of Hamlet's murder of her father Polonius).

Business Information Systems

Business Information Systems HA(IT) My questions: 1. Define the concept information system and its constitutive elements; describe the broad categories of computer-based information systems, providing relevant business examples for each category identified; explain how computer-based information systems can support managers at each level of an organisation. 2.Explain the main elements and steps of the project management process and, considering your essay writing as a project, provide a concrete description including numbers for that project; relate the main project management steps to the main phases of the systems development life cycle model; how are the life cycle phases handled in the V-model and the spiral model? 3. What is the Information Systems and Information Technology Function in an organization; what needs to be managed; how can the IS/IT function be organized; what does outsourcing mean and which role does it play in this context?Characters (with spaces) and 1 figure: 2 2645 Question 1 Information Systems To understand and define an Information System (IS) thoroughly, it’s important to separate the two words and understand them separately. Information is produced by processing data so that it is meaningful which can be not only understood by the recipient but also used to meet a specific goal or requirement. To understand information, data needs to be understood as well. Data are raw facts like a specific date or measurement. Data needs to be processed and transformed into information; this process is called the transformation process. E. . data regarding sales of a firm is useless unless putting it in the correct context. But if you sort the sales after type of product, you will be able to see what product has been sold the most. By using data to gain relevant information, it’s possible to reduce the uncertainty of different questions and thereby improve the decision making. A system can be found in every part of the world. A system is a set of interrelated components that work together towards a common goal. The solar system might not a have an obvious goal while a firm might have several goals like gaining profit or making the best product possible.To achieve these specific goals the system will need to obtain inputs and transform these into outputs, like described in the transformation process, data is seen as the input and information as the output. But to transform input into output isn’t enough. The output needs to be relevant compared to the objective(s) of the firm. For systems to be more effective the system can contain a feedback and control stage as well. By using the information we have just gathered it’s possible to define IS. IS is defined as the way people and organizations are gathering, storing and processing information.In a business the IS will contribute to making the correct decisions. But IS isn’t solely used for managers and workers’ decision making it can als o be used in other ways, like feedback for an organization’s quality. Computer-based information systems Today most IS involve Information Technology (IT) to create management information also called computer-based information systems. This is because of the many disadvantages it gives not having a computer-based information system. An IS can be divided into two categories called Operations Information Systems (OIS) and Management Information System (MIS).OIS contains 3 sub-systems each contributing in the daily running of a business. The 3 sub-systems of the OIS are: The Transaction Processing System (TPS), Office Automation Systems (OAS) and the Process Control Systems. The TPS is managing the many transactions occurring on daily basis on the operational level of an organization like withdrawal of money from an ATM, or orders and payments for goods and services. Even though the TPS is marked by a lot of repetitive tasks and routine, the function of it is essential and missi on-critical to an organization. A TPS will e. g. secure that an ATM is running correctly.If a person wants to withdraw money from his account via an ATM, the TPS will make sure that there’s enough money on the customer’s account so that the money can be withdrawn. The transaction will only take place if all tasks in the process can be completed. OAS is a common system within the OIS. OAS refers to the way that basic tasks in an office have been computerized. Before creating, storing and managing information was done physically, but by computerizing the office the time taking to create documents or arrange meetings is done faster, giving more time for the organization to take care of other tasks.The OAS helps making the office more than just an area for typing but an area for exchanging important knowledge about the organization by still reducing costs as well. If a manager wants to set up a meeting instead of giving a paper to each participant, he can choose to send an e-mail to all the participants even though they aren’t at the same location. The process control system deals with large amounts of data created by production processes.The process control system is used to control and support the different manufacturing processes of an organization. The process control system will automatically control the flow of the manufacturing process by a specific limit set by the user, and might e. g. support the production of a standard product like the Model T Ford car. The MIS contains three sub-systems. All three systems are supporting decision-making in a business and are called: Decision Support Systems (DSS), Information Reporting Systems (IRS) and the Executive Information Systems(EIS).DSS uses raw data along with different business models to provide useful information for the manager which he can use for making tactical and strategic decisions, being especially semi-structured or unstructured. The DSS is often created by end-users, because t hey often have the much needed knowledge about the organization compared to a bespoke or on-the-shelf package developed by a third party. An example is the expert system which contains the knowledge and decision making skills of specialists, giving none-specialists enough knowledge to make decisions.In the world of medicine, it’s possible for a nurse to enter the symptoms of a patient. The system will then compare the entered symptoms with all the different symptoms of different diseases already stored in a knowledge base and provide a diagnosis. A problem with the DSS is that the more options the system has the more complex it gets. IRS uses information to produce predefined reports for the day-to-day decision-making. There are two commonly known reports used by the IRS being the periodic and exception reports. The periodic reports is required by decision makers at regular intervals, it can e. . provide a report showing the sales of a product from day-to-day. The exception r eport is only being produced when needed; it might be produced automatically if a performance measure moves outside a predefined range. EIS is mostly used for the strategic decision making by senior managers to monitor, compare and analyze and thereby support the decision-making process of the senior manager. EIS could e. g. notify the senior manager with specific information about a facility anywhere in the world underperforming, giving him enough information to make a decision about the future of the facility.The different IS just described are each used at different levels of an organization. The top leaders of an organization are all placed in the strategic level, where unstructured decisions are a big part of the management. They mainly use EIS to support their decisions but it’s important to notice that their decisions tend to rely on their own knowledge and experience as well. At the tactical level of an organization the expert and decision support systems are used to support the semi-structured decisions being made at this level.The operational level of an organization makes a lot of structured decisions because of their little authority; therefore the TPS is used by the workers at this level on a day-to-day basis. The higher up we come in the organization the more unstructured the decisions are because of the level of authority rises. But this isn’t always true; it is possible to make unstructured decisions at the operational level as well as structured decisions at the strategic level. E. g. in a hospital the doctors (who work at the operational level) often have the authority to make important and less structured decisions.Question 2 The project management process There are three key elements of the project management process being time, cost and quality. BIS (Business Information Systems) projects are likely to consume a lot of time and money and involve many parts of the specific organization; the project manager therefore has a big responsibility for the failure or success of a project and whether or not the project is following the time, cost and quality requirements given. The use of a well-structured project management process has the ability to highly reduce the chance of a BIS projects failure.The project management process has four steps being: Estimation, schedule/plan, monitoring and control, documentation. The estimation step gives the project manager time to plan how much time and effort the project will take to fulfill the given requirements. The overall project requirements will be compared to the available resources. In the early stages of the project it’s often hard for the project manager to give precise estimations because of the great amount of uncertainty, but the project will often be constrained by a deadline or the type of people and hardware available.Effort time and elapsed time is two important terms used to explain the amount of work different tasks will take. Effort time explai ns the total amount of work needed to complete a task while the elapsed time indicates how many calendar days the task will take. A project’s estimation will often change a lot from the start and to the end of a project because of the many constraints and changes that can occur. The requirements might change or hardware might break down, but a good estimation is essential to the success or failure of a project.The schedule/planning step is about determining when a project should be executed; the finished schedule is then called the plan. There are two main terms important to notice called the serial and parallel relationship. The serial relationship describes how some activities have to be completed before another activity can start. The parallel relationship explains how some activities can be totally independent, but that four activities might need to run in parallel before an implementation can occur. Monitoring and control is a very important step which ensures that the t asks of a project are meeting the requirements.This is done by monitoring the different tasks; if the project isn’t running as planned and is deviating from the given requirements, controls might need to be made for the project not to fail. To disseminate the information provided during project execution an essential step is documentation. It’s the project manager’s task to make sure that good documentation is provided from the different parts of the project. With poor documentation or without any information at all, the project might not deliver on time and the expenses of maintenance will most likely increase.It’s also important that the documentation provided is acceptable and understandable. My project: To support my project planning a Gantt chart was made to show an overview of the activities. Project startup describes my first day of the project; I chose my questions and estimated the overall process of the project. I wanted to use three days on eac h question, all though I have to use four days on question 2 because of other homework. My writing will compared to my estimation be finished on the 30-okt and I will thereafter be editing the project. The product has to be finished and delivered on the 2-Nov.If the project isn’t delivered on the 2-Nov the project will fail. The different tasks being question 1, 2 and 3 are in this project all independent but I chose to run them in a parallel relationship with the editing task so that before the editing task can occur, the three questions have to be answered. This gives me an overview of the size of my project and whether or not the project has to be shorter. I have been executing the project as planned so far regarding time (today 22-okt), but looking at the size of my project so far, I’m going need more time than estimated on cutting the project in the editing phase.Relation between the project management steps and the SDLC The main phases of the System Development L ife Cycle (SDLC) are by order: Initiation, feasibility study, requirement analysis, system design, build, implement, maintain and kill. The estimation step is used in almost all of the SDLC stages, and will be used more frequently in some stages depending on the type of project. In the initiation stage of the project the project manager will use estimation to make an overview of the project, estimating the different resources that are required to carry out the project, but the estimation isn’t detailed yet.A detailed estimation will be produced when the project has been determined feasible and is under or close to production. The leader will estimate whether or not the project is feasible at the feasibility stage by using the information granted through interviews and reports. In the analysis stage the requirements for the new system will be specified. After the requirements have been established it’s possible to make a detailed estimation of especially the work requir ed at the design and build phase.The estimations will often be much more precise if timings from the previous projects are available. The scheduling and planning step runs alongside the estimation step. By knowing how much time and effort is needed for the project, it’s possible to make a more precise schedule of the process of the project. It’s important to always have a schedule of the plan for the project, but the most effective schedule will be made after the detailed estimation has been produced at the analysis phase (it can be produced at other steps depending on the project).Once the schedule has been produced, the monitoring and control step will monitor the performance at all of the SDLC stages and ensure that the project is following the schedule/plan and fulfilling the requirements. It’s essential to monitor all of the SDLC stages since deviating from the plan can result in a project failure. Documentation is important during the whole project but esp ecially essential at the development and maintenance phases. This is because most projects are based on team efforts.Not only does the documentation allow monitoring and controlling, but it allows the different members of a development team to disseminate their design information between each other, making their work more effective. The V- and spiral model The V-model’s V describes the graphical overview of the relationship between the different tests and SDLC phases, but the V is also a synonym for verification and validation. The verification will check if there is any better solution to the design of the product, and that the design we are building is without errors or bugs.The validation is used to test the design of the product and check whether the design is fulfilling the requirements. Validation and verification forms the basis for producing tests. The tests shown in the V-model are used during implementation which is why the model has the V-shape. But it’s i mportant to notice that the life cycle phases on the left side have to occur, before the tests on the right side of the model can occur. A concern about the V-model is that it has no maintenance phase, meaning that it’s possible to believe that the product is finished and bug-free when signed off.The SDLC can also be used via the spiral model. The spiral model is an iterative system. The three stages of analyzing, design and coding often tend to be repeated as a part of the prototyping process, and this is why the spiral model was made. The spiral model consists of four main activities: Planning, risk analysis, engineering and customer relation. The model contains all of the elements of the SDLC but it also contains risk assessment. By being able to make several iterations it’s possible to make a more detailed production and to add in new elements to the production because of the repetition. Question 3 The IS/IT functionThe goal of using IS/IT is the hope that it will generate more benefit than the costs used on it. The function of IS in an organization, is to make the management process effective and support it. IT is the tools like hardware and software that the organization uses so IS can run and be built. Managing the IS/IT functions When managing IS there are different areas that need to be managed. It’s important to manage the development of the different business systems. When migrating from one system to another it’s important to have a project leader, as well as to manage and make sure that the migration is going as planned.When inventing end-user applications, it’s important to have management to make sure that the software being produced isn’t full of bugs, and isn’t a reinvention. Other important areas that needs to be managed is the database administration, user support and training, shared services and the IS/IT staffing. It’s also important to manage different areas of IT. Some of the areas that need to be managed are which hardware platforms to use in the organization, the manager might choose to only use the client/server environment.Good network architecture is also vital to an organizations sharing of information, and therefore it’s important that this area is managed. Many organizations use a lot of money on IT, and many big organizations have large amounts of IT including development tools. If this area isn’t managed, new tools being bought might not be compatible with the chosen database management systems or the selected hardware platforms. If an organization is using legacy systems, these needs to be managed so that it can still operate with newer systems (this might be an IS area as well).A final important area to manage is the operations management which contains hardware management, capacity planning, security, technical support, telecommunications and network management. Organizing the IS/IT functions To organize the different functions of I S/IT isn’t easy, but an essential part of making IS/IT more effective in a business. It’s possible to ether centralize or decentralize when organizing the IS/IT function in a business. When centralizing, the IS/IT management will be placed in one specific spot in the organization from where all of the functions of IS/IT will be managed.This could for example be the MIS, which will then be reporting to an IT director or another head of the department. Decentralization is the opposite of centralizing and means that the IS/IT functions will be spread out across the organization by having small IS/IT groups stored in different parts of the organization. It’s hard for organizations to be 100 % centralized or decentralized all though many organizations tend to focus on one of them. Outsourcing Outsourcing is a term used when a company chooses to subcontract a service to a third party. This service can be catering, cleaning, public relations and IS.Outsourcing of IS ma nagement has become a major term in many companies in the world today because of its many benefits and uses. Some of these are cost reduction, quality improvement, risk reduction and to enable a focus on the core business. In a 2009 IBM survey of 2500 CIO’s worldwide 76% of the respondents anticipate to have a strongly centralized infrastructure in five years. A highly centralized IS/IT function does as mentioned before contribute to cost reduction, and having the function in one place makes it easier for companies to take advantage of developments like outsourcing.By seeing more companies outsourcing and more companies wanting to centralize which both contribute to a lower cost might not be a coincidence, and can be a way of saying that IT is more than just a support capacity for the outsourcing/centralizing organizations. Outsourcing plays a huge role in the management process as well. The problem with outsourcing and its relationship with the management process is the impo rtance of making outsourcing work. Outsourcing might be a huge trend, but this doesn’t necessarily mean that it’s going to work.Many company’s outsourcing projects tend to fail because of bad management and contracts with the third-party. The failure of many outsourcing projects can have a connection between the management and organizing of the IS/IT functions. If the management and organizing of the IS/IT functions isn’t managed well or if the company isn’t seeing IS/IT as an important part of the company’s strategy, outsourcing has a bigger chance of failing.

Night World : Spellbinder Chapter 9

I he shoe was so incongruous that for an instant Thea thought her eyes must be playing tricks on her. It was the atmosphere here-the dim, echoing room with all its macabre booths. If she looked away and then looked back†¦ It was still there. I should wait, I should call somebody. This could be something terrible. There are human authorities; I should at least wait for Eric†¦. Thea found herself moving in dreamlike, slow speed. She took the edge of the oilcloth between finger and thumb and lifted it just an inch or so. There was a leg attached to the shoe. A blue-jeaned leg. Not part of a dummy. And another shoe. Horror and adrenaline washed over Thea. And, strangely, that helped. Her first thought was. It's a person and she may be hurt. She went into emergency mode, slamming a wall between herself and her fear. Hang on, are you okay, just let me see†¦ She pulled the rest of the oilcloth off, tugging to get it free. She saw legs, a body, curled fingers clutching the sleeve of a black-dressed witch dummy†¦ Then she saw the head and she reeled backward, both hands pressed over her mouth. She'd only gotten a glimpse, but the picture was burned into her mind. Blue-gray face, hideously swollen. Grotesquely bulging eyes. Tongue like a sausage protruding from between black lips†¦ Thea's knees gave out. She'd seen the dead before. She'd been to leave-taking ceremonies where the mortal remains of witches were returned to the earth. But those had been natural deaths, and the corpses had been peaceful. While this†¦ I think it was a boy. It had short hair and a flat chest. But there was no way to recognize the face. It was so distorted-didn't even look human†¦. He died violently. May his spirit be released; not held here by the need for revenge. Oh, Sekhmet, lion-headed goddess of Egypt; Mistress of Death, Opener of Ways, Sekhmet Who Reduceth to Silence†¦ Her disjointed thoughts were interrupted as sunlight fanned into the room. At the door, Eric shouted, â€Å"I'm back!† Thea stood up. Her legs wanted to cave again. She opened her mouth, but what came out was a whisper. â€Å"Eric-â€Å" He was hurrying toward her. â€Å"What's wrong? Thea?† â€Å"It's somebody dead.† She saw his eyes widen in absolute disbelief-and then he looked past her. He took a step toward the thing on the floor, stopped, crouched, and stared for a second. Then he whirled back and grabbed her as if he could somehow protect her from what he'd seen. â€Å"Don't look at it; don't look over there,† he gasped. â€Å"Oh, God, it's bad.† * â€Å"I know. I saw it.† â€Å"It's bad; it's so bad†¦.† They were both holding on to each other. It was the only safety in this nightmare. â€Å"He's dead. That guy is dead,† Eric said. It was obvious, but Thea understood the need to babble. â€Å"There's nothing we can do for him. Oh, God, Thea, I think it's Kevin Imamura.† â€Å"Kevin?† Black dots danced in front of Thea's eyes. â€Å"No, it can't be-â€Å" â€Å"I've seen him wearing that shirt before. And the hair†¦ And he's on the committee to decorate this place. He must have been setting up that dummy.† Thea's mind showed her a terrible picture. A crusted dark line on that bloated face-like the wound made by a slashing razor. And the soft black hair†¦ Yes, it could have been Kevin. And that meant- Blaise. â€Å"Come on,† Eric was saying, his voice dazed and quenched. â€Å"We've got to tell the office.† Numbly, Thea let him guide her. Her mind was in another place. Blaise. Did Blaise know†¦ could Blaise have†¦ She didn't want to form the thought even to herself, but she couldn't help it. †¦ finally gone all the way? Not just spilled blood, but taken a life? It was forbidden to witches. But the Harmans were part lamia, and vampires sometimes killed for power. Could Blaise have gone that far into the darkness? After they got to the office, things happened fast, but Thea couldn't really take it in. Activity whirled around her. The secretaries. The principal. The police. She was grateful for Eric, who kept telling the story over and over so she didn't have to. I need to find Blaise. They were back at the gym. The police were cordoning off the whole building with yellow tape. A throng of students and teachers was watching. Thea's eyes skimmed the crowd, but she didn't see Blaise anywhere. Voices rose around her. â€Å"I heard it was Kevin Imamura.† â€Å"Somebody said that guy from the dance came back and got him.† â€Å"Eric! Eric, did you really see him?† Then one voice outshouted the others. â€Å"Hey, Mrs. Cheng, what about the Halloween party? Is the gym gonna be open by then?† The principal, who had been huddled with a couple of police officers, turned around. Black hair riffling over her forehead in the breeze, she addressed the entire crowd. â€Å"I don't know what is going to happen with the gym. There's been a tragedy, and now there's going to be an investigation. We'll just have to wait and see what comes of that. Now, I want everybody to go back to their classes. Teachers, please take your students back to your classrooms.† â€Å"I can't go back,† Thea whispered. She and Eric were standing at a little distance from the thinning crowd. Everyone seemed to have forgotten about them. â€Å"I'll take you home,† Eric said immediately. â€Å"No-I need to find Blaise. I have some things to ask her.† She tried to make her stupefied brain work. â€Å"Eric, I should have told you this before. You've got to be careful.† â€Å"Of what?† â€Å"Of Blaise.† He looked incredulous. â€Å"Thea†¦Ã¢â‚¬  He glanced at the old gym. â€Å"You can't think she had anything to do with-what happened to Kevin.† â€Å"I don't know. She could have had somebody do it-or made him do it himself.† Thea kept her voice low. She looked straight into Eric's face, willing him to believe her. â€Å"Eric, I know you don't understand, but it's like I told you before. She's like Aphrodite. Or Medea. She laughs when she destroys things. Especially when she gets mad†¦ and she's mad at you.† â€Å"Why?† â€Å"Because you picked me instead of her-because I like you-lots of things. That doesn't matter. The point is that she may come after you. She may try to†¦ seduce you. And†-Thea glanced at the bobbing yellow tape surrounding the old gym-â€Å"she may try to hurt you. So will you just be careful if you see her? Will you promise me that?† Eric looked windblown and bewildered, but he nodded slowly. â€Å"I promise.† â€Å"Then I'll see you later. We still have things to talk about-but I have to find Blaise first.† She walked toward the crowd, leaving Eric standing there in the wind. She knew he was watching her. . A waving hand caught Thea's eye. It was Dani, her face full of sympathy and concern. â€Å"Thea, are you all right?† â€Å"Sort of.† Thea gave a laugh she didn't recognize. â€Å"Have you seen Blaise around?† Dani's soft little hand crept into hers. â€Å"She and Vivienne went home-I mean, to your place. I'll go back with you, if you want. You shouldn't be alone.† Thea squeezed her hand. â€Å"Thanks. I'd appreciate it.† She was grateful-and relieved that Dani didn't hate her. â€Å"Dani-about the way I acted earlier†¦Ã¢â‚¬  â€Å"Forget it. I don't know what I said, but I didn't mean to make you mad.† She added gently, â€Å"Thea, are you really okay? Really? Because I don't want to upset you more†¦.† â€Å"Why?† And then: â€Å"What, Dani?† â€Å"Your grandma's sick. That's why Blaise and Vivienne went home-Vivienne's mom paged her. She's a healer-Vivienne's mom, I mean-and I think she's taking your grandma to her house.† Thea was disturbed. Gran hadn't moved to Las Vegas for the same reason other Night People did. Lamia and made vampires came because so many of the humans here were transients-the kind that wouldn't be missed if they disappeared. Other witches came because of the power vortexes in the desert. But Gran had come because of the warm, dry climate. Her lungs had been bad since she was a kid. Please don't let it be serious, Thea kept thinking as Dani drove her home. She felt as if her skin had been rubbed too thin all over her body. When they got to the shop, Gran was already gone. Tobias and Vivienne were downstairs. â€Å"Is she okay?† Thea asked. â€Å"Is it something bad?† â€Å"Not too bad,† Tobias said. â€Å"She just kept getting dizzy today, and then she had a coughing fit and couldn't stop. She finally decided maybe she'd better get somebody to sing it out. So she called Ms. Morrigan.† Oh, great-chanting. Just what Gran loved. But she must have been really sick to ask to have it done. â€Å"Can I call her?† â€Å"I wouldn't,† Vivienne put in. Her green eyes were kind, her voice reassuring. â€Å"I'm sure Mom's working on her by now, and when she does a singing, it takes all night. You shouldn't disturb them. But don't worry, Thea-my mom's really good.† â€Å"Yes-it's not that I'm worried about.† Thea looked around distractedly, finally coming back to Vivienne's face. â€Å"Did you hear about what happened at school?† â€Å"No.† Vivienne looked mildly curious. â€Å"What happened?† Instead of answering, Thea said, â€Å"Where's Blaise?† â€Å"Upstairs packing. She's going to stay overnight at ray house. You can come, too-Thea?† Thea was already racing up the stairs. She burst into the bedroom she and Blaise shared. Blaise had a small suitcase open on her bed. Thea didn't waste words. â€Å"Did you kill Kevin Imamura?† Blaise dropped a black silk teddy. â€Å"Did I what? What are you talking about?† â€Å"He's dead.† â€Å"And you thought I did it? Thanks a lot, but it's not him I want to kill.† Blaise narrowed her eyes and Thea felt cold. Then she tilted her head. â€Å"So how did he die?† â€Å"He was strangled. Somebody murdered him.† Blaise just raised her eyebrows and murmured, â€Å"Hm. I wonder where Randy is?† She held a shirt up, considered it, and added, â€Å"Do you want to come stay at Viv's with me? It's better than staying here by yourself.† â€Å"I don't know. Do I have to watch you to make sure Eric doesn't end up like Kevin?† Blaise gave her a scorching look. â€Å"When I go after a boy, I get him first. I don't strangle him before the fun begins.† She slammed her suitcase closed and stalked out. Thea sat on the bed. In spite of her sharp words, Thea now knew Blaise hadn't done it. Her cousin had been genuinely surprised. And Randy? I suppose it could have been, if he somehow got out of wherever they've taken him. He had a reason to hate Kevin. But†¦ The alternate explanation slid into place so quickly that Thea realized it must have been in her mind all along. The spirit. She sat there for an endless time, trying to think. It was like trying to find her way through a thick fog. Gran's gone†¦ and if she's sick I can't bother her anyway†¦ of course, Blaise won't help†¦ but I need to trust somebody†¦. Dani gently pushed the door open. â€Å"Can I come in?† When Thea nodded, she walked in and sat down on Blaise's bed. â€Å"They left. I told Tobias to go too-he had a girlfriend he wanted to see. I'll stay here tonight, if you want.† Thea took a shaky breath. â€Å"Thanks, Dani.† â€Å"Look, Thea, I don't want to pry, but†¦ are you okay? I mean, you're as pale as a corpse-† Dani bit her lip. â€Å"Sorry, bad choice of words. But I am your friend, and if there's anything I can do, I'd like to help.† Another breath. Then Thea made her decision. â€Å"I worked a forbidden spell.† Dani looked shocked, but not appalled. â€Å"Which one?† â€Å"Calling back the spirits.† When Dani didn't scream or faint, Thea told the whole story. All about her summoning-everything except why she'd been doing it. â€Å"And now I'm scared,† she finished. â€Å"I let something out yesterday, and today Kevin gets murdered. Blaise didn't kill him. She thinks Randy may be involved, but†¦Ã¢â‚¬  Thea shook her head. â€Å"But, Thea, be logical. Why should it have anything to do with your spell?† Dani's rational voice was soothing. â€Å"You let someone out, not something. The elders summon the ancestors all the time without anything bad happening. You just feel guilty because you know you weren't supposed to be doing it.† â€Å"No. Dani, I can't explain it, but the thing I let out-it wasn't friendly. It knocked Blaise and me down. None of the spirits I saw the elders summon ever did that.† â€Å"Well†¦Ã¢â‚¬  Dani looked doubtful. â€Å"But why would one of the ancestors went to murder a human?† â€Å"I don't know.† Somehow talking about it had cleared Thea's mind. She said slowly, â€Å"But†¦ maybe the book would tell us.† Ten minutes later, they were sitting side by side on Thea's bed, with the iron chest on the floor and the book between them. â€Å"First, could you tell anything about the amulet that fell in the fire?† Dani asked in scientific tones. â€Å"Like, if the hair was gray, it could mean-â€Å" â€Å"The witch was old.† Thea caught on immediately. â€Å"No, it wasn't gray or white. It was dark-sort of like mahogany.† She closed her eyes, trying to remember. â€Å"It all happened so fast-but I think it was long. It was doubled up lots of times in the clay.† â€Å"So maybe a woman.† â€Å"Yes.† Thea read for several minutes. â€Å"Wait a minute. Look at this.† † ‘Suzanne Blanchet,' † Dani read with difficulty. † ‘Bom sixteen thirty-four in Esgavans on the day that they made bonfires for the peace between France and Spain. Tried sixteen fifty-three at Ron-chain, prisoner at the court of Rieux.' â€Å" â€Å"And listen to the charges,† Thea said grimly. † ‘Bewitching men's corn, killing cattle, bringing hunger into the country, and strangling babies at night with her long hair.' â€Å" â€Å"Strangling,† Dani breathed. â€Å"She denied it, so they tortured her. Listen: ‘Being a little stretched on the rack, she screamed ceaselessly that she was not a witch, but being more tightly stretched, said that it was true.' â€Å" â€Å"And then they tortured her family,† Dani said, her finger skimming the lines. â€Å"Oh, Isis, look at this. She had a ten-year-old brother named Clement and a six-year-old sister named Lucienne. They tortured them both.† â€Å"And burned them.† Thea had begun to tremble involuntarily. The room wasn't cold, but she had a feeling like ice deep inside her. â€Å"Look. ‘The children having been promised the mercy of being strangled before burning, but the executioner not having been paid, they were committed alive to the flames†¦'.† She couldn't finish. † ‘†¦ before the eyes of their sister,' † Dani whispered. She was shaking, too, and huddling close to Thea. â€Å"How could they do that?† â€Å"I don't know,† Thea said flatly. â€Å"I mean, no wonder Night World laws are so strict. No wonder we have to keep ourselves a secret-look at what they do to us when they find out.† | Thea swallowed-she didn't want to think about Night World rules. â€Å"And then they burned Suzanne,† she said quietly, keeping her eyes on the book. † ‘Being consigned to the fire, she uttered several exclamations, crying out upon revenge.' â€Å" â€Å"I would too,† Dani said, her soft voice threaded with steel. â€Å"I'd come back and kill them.† She stopped and she and Thea looked at each other. â€Å"And maybe that's just what she did,† Thea said slowly. â€Å"Only she couldn't get to her torturers. But she found something that looked similar-a reproduction torture chamber. And there was Kevin, doing something to a witch dummy-hanging it, maybe. Maybe treating it in some way that reminded her of†¦Ã¢â‚¬  Thea nodded toward the book. â€Å"Anyway, doing something that made her lose it.† â€Å"And kill him. By strangling him-what she'd been accused of doing. Thea?† Dani grimaced, then went on. â€Å"When you saw Kevin's body-was there anything around his neck?† Thea stared at the window curtains, trying to remember. That awful bloated face†¦ the protruding tongue†¦ and dark bruises on the throat. â€Å"No,† she said softly. â€Å"There were marks-but whatever strangled him was gone.† â€Å"She took it with her.† Dani shivered, then put both hands on the book. â€Å"Or maybe not. Look, Thea, this may make a great bonfire story, but, really, it's all speculation.† Thea was staring at the yellowed page beneath Dani's fingers. â€Å"I don't think so,† she said quietly. â€Å"See this symbol by Suzanne Blanchet's name? I recognize it. I saw it for just a second-on the amulet in the fire.† â€Å"You're sure?† Thea looked away. â€Å"Yeah. It's her, Dani. And it's my fault. I let her out†¦ and now she's killing people. Because of me, somebody's dead.† It was only when she said it that the full realization hit-as if forming the words had somehow made it true. Kevin was dead. He wasn't going to school anymore, he wasn't going to get a chance to repair his Porsche. He wouldn't ever smile at a girl again. He'd lost everything a person had to lose. â€Å"And I just-I just feel so bad,† Thea said. The ache in her throat rose up in a sort of spasm, as if she were going to be sick. But what came out was tears. Dani held her while she sobbed. And at last, when Thea was crying more quietly, she said, â€Å"You didn't know. You didn't mean to do anything bad. You were just playing around and it went wrong. You didn't know.† â€Å"It doesn't matter.† Thea wiped her face on her sleeve, sitting up. The ache in her chest was duller now, and she was slowly realizing that something else was there, something that felt hot and bright. A need to act. â€Å"It doesn't matter,† she said again. â€Å"I still made it happen. But I'll tell you one thing-I'm not going to let it keep happening. I've got to stop her. Which means I've got to send her back.† â€Å"I'm with you there,† Dani said, her small jaw set in determination. â€Å"But how?† Thea stared at the wall a moment, then said, â€Å"I have an idea.†

The Role of Interjections in English Grammar

The Role of Interjections in English Grammar Shortly after Steve Jobss death in the fall of 2011, his sister, Mona Simpson, revealed that Jobss final words were monosyllables, repeated three times: OH WOW. OH WOW. OH WOW. As it happens, interjections (such as oh and wow) are among the first words we learn as children- usually by the age of a year and a half. Eventually, we pick up several hundred of these brief, often exclamatory utterances. As the 18th-century philologist, Rowland Jones observed, It appears that interjections make up a considerable part of our language. Nevertheless, interjections are commonly regarded as the outlaws of English grammar. The term itself, derived from Latin, means something thrown in between. Why Interjections Are Overlooked Interjections usually stand apart from normal sentences, defiantly maintaining their syntactic independence. (Yeah!) They arent marked inflectionally for grammatical categories such as tense or number. (No sirree!) And because they show up more frequently in spoken English than in writing, most scholars have chosen to ignore them. (Aw.) Linguist Ute Dons has summarized the uncertain status of interjections: In modern grammars, the interjection is located at the periphery of the grammatical system and represents a phenomenon of minor importance within the word class system (Quirk et al. 1985: 67). It is unclear whether the interjection is to be considered an open or closed word class. Its status is also special in that it does not form a unit with other word classes and that interjections are only loosely connected with the rest of the sentence. Furthermore, interjections stand apart as they often contain sounds which are not part of the phoneme inventory of a language (e.g. ugh, Quirk et al. 1985: 74).(Descriptive Adequacy of Early Modern English Grammars. Walter de Gruyter, 2004) But with the advent of corpus linguistics and conversation analysis, interjections have recently begun to attract serious attention. The Study of Interjections Early grammarians tended to regard interjections as mere sounds rather than words- as outbursts of passion rather than meaningful expressions. In the 16th century, William Lily defined the interjection as a parte of speche, whyche betokeneth a sodayne passion of the mynde, under an unperfect voice. Two centuries later, John Horne Took argued that the brutish, inarticulate interjection . . . has nothing to do with speech, and is only the miserable refuge of the speechless. More recently, interjections have been variously identified as adverbs (the catch-all category), pragmatic particles, discourse markers, and single-word clauses. Others have characterized interjections as pragmatic noises, response cries, reaction signals, expressives, inserts, and evincives. At times interjections call attention to a speakers thoughts, often as sentence openers (or initiators): Oh, you must be kidding. But they also function as back-channel signals- feedback offered by listeners to show theyre paying attention. (At this point, class, feel free to say Gosh! or at least Uh-huh.) Its now customary to divide interjections into two broad classes, primary and secondary: Primary interjections are single words (such as ah, ouch, and yowza) that are used only as interjections and that dont enter into syntactic constructions. According to linguist Martina Drescher, primary interjections generally serve to lubricate conversations in a ritualized manner.*Secondary interjections (such as well, hell, and rats) also belong to other word classes. These expressions are often exclamatory and tend to mix with oaths, swear words, greeting formulas, and the like. Drescher describes secondary interjections as derivative uses of other words or locutions which have lost their original conceptual meanings- a process known as semantic bleaching. As written English grows more and more colloquial, both classes have migrated from speech into print. One of the more intriguing characteristics of interjections is their multifunctionality: the same word may express praise or scorn, excitement or boredom, joy or despair. Unlike the comparatively straightforward denotations of other parts of speech, the meanings of interjections are largely determined by intonation, context, and what linguists call pragmatic function. Geez, we might say, you really had to be there. Ill leave the next-to-last word on interjections to the authors of the Longman Grammar of Spoken and Written English (1999): If we are to describe spoken language adequately, we need to pay more attention to [interjections] than has traditionally been done. To which I say, Hell, yeah! * Quoted by Ad Foolen in The Expressive Function of Language: Towards a Cognitive Semantic Approach. The Language of Emotions: Conceptualization, Expression, and Theoretical Foundation, ed. by Susanne Niemeier and Renà © Dirven. John Benjamins, 1997.

Population Density Information and Statistics

Population Density Information and Statistics Population density is an often reported and commonly compared statistic for places around the world. Population density is the measure of the number of people per unit area, commonly represented as people per square mile (or square kilometer). The population density of the planet (including all land area) is about 38 people per square mile (57 per sq km).  The population density of the United States is approximately 87.4 people per square mile, according to the 2010 U.S. Census. Computing Population Density To determine an areas population density, divide an areas total population by the land area in square miles (or square kilometers). For example, Canadas population of 35.6 million (July 2017 estimated by the CIA World Factbook), divided by the land area of 3,855,103  square miles (9,984,670  sq km) yields a density of 9.24 people per square mile.   Although this number would seem to indicate that 9.24  people live on each square mile of Canadian land area, the density within the country varies dramatically; a vast majority lives in the southern part of the country. Density is only a raw gauge to measure a populations disbursement across the land. Density can be computed for any area,  as long as one knows the size of the land area and the population within that area. The population density of cities, states, entire continents, and even the world can be computed. What Country Has the Highest Density? The tiny country of Monaco has the worlds highest population density. With an area of three-fourths of a square mile (2 sq km) and a total population of 30,645, Monaco has a density of almost 39,798 people per square mile. However, because  Monaco and other microstates have very high densities due to their extremely small size, Bangladesh (population 157,826,578)  is often considered the most densely populated country, with more than 2,753 people per square mile. What Country Is the Most Sparse? Mongolia is the worlds least densely populated country, with only five people per square mile (2 per sq km). Australia and Namibia tie  for a close second with 7.8 people per square mile (3 per sq km). These two countries are further examples of density being a limited statistic, as Australia may be huge, but the population resides mainly on its coasts. Namibia has the same density figure but a much smaller total land area. Most Tightly Packed Continent Perhaps not surprisingly, the most densely populated continent is Asia. Here are the population densities of the continents: North America - 60.7 people per square mileSouth America - 61.3 people per square mileEurope - 187.7 people per square mileAsia - 257.8  people per square mileAfrica - 103.7 people per square mileAustralia - 7.8 people per square mile Most Densely Populated Hemisphere About 90 percent  of the Earths people live on 10 percent of the land. Additionally, about 90 percent of the people live north of the equator in the Northern Hemisphere.

Five Ways to Look Up

Five Ways to Look Up Five Ways to Look Up Five Ways to Look Up By Maeve Maddox ESL learners have a tough row to hoe when they set themselves to learn English idioms. Note: â€Å"to have a tough row to hoe† = â€Å"to have a difficult task to carry out.† For example, each of the following sentences contains the verb look and the word up, but each conveys a different thought: 1. It’s a surprise! Keep your head down and don’t look up. In this sentence, up functions as an adverb modifying the verb look. In this context, â€Å"to look up,† means, â€Å"to direct one’s gaze upward.† 2. Before you use an unfamiliar word, be sure to look up the meaning. Here, â€Å"to look up† is a phrasal verb with the meaning â€Å"to search for an item of information, or seek information concerning (a person or thing), in a book or database, on the Internet, etc.† 3. Many youngsters look up to professional athletes. In this context, â€Å"to look up to† is a phrasal verb meaning, â€Å"to have a great deal of respect for, to admire, venerate.† 4. While I’m in Chicago, I intend to look up my old college roommate. This colloquial use of â€Å"to look up† means â€Å"to visit or contact a person, especially for the first time or after loss of contact. 5. My financial planner assures me that the economy is about to look up. This idiom is most commonly used in the progressive tense: â€Å"Things are looking up.† The meaning is â€Å"improving, getting better.† From the verb â€Å"look up† (to seek information) comes the noun lookup, a computer term meaning â€Å"the action or process of looking something up in a database.† Lookup is also used as a qualifier: I often  use the Passage Lookup to compare English translations from the NIV, ESV, NASB, and NKJV.   The  lookup feature  allows you to quickly search your contact manager or PIM (personal information manager) for phone numbers to dial. On my iPad, the  lookup feature  isnt working right for certain entries. Want to improve your English in five minutes a day?

Managerialism in social work Essay Example | Topics and Well Written Essays - 2500 words

Managerialism in social work - Essay Example The research suggests that such managers were more oriented to profit, and were more capable of obtaining it, than the traditional owner-managers (J. Harris; 1998, p. 839-8620). This British evidence fits with the range of evidence from the USA and other countries assembled dismiss the thesis of the managerial revolution and establishes that the claim of a separation of ownership and control is well described as a 'pseudo fact'. He points out that 'growth, sales, technical efficiency, a strong competitive position are at once inseparable managerial goals and the determinants of high corporate profits'. These corporate profits are the prerequisites of high managerial income and status. The high status and material rewards which can be achieved by membership of a managerial occupation are dependent on the contribution made to profit achievement or at least to the continued survival of the corporation in a context where too great a deviation from profitable performance would lead to collapse or takeover. The ownership of wealth and the control of work organizations are closely related, on the basis of this kind of evidence. It is the case, however, that owners hip of enterprises is far more dispersed than it was in the past with the growth of an 'impersonal' structure of possession which has not, however, 'resulted in a loss of power by wealthy persons'; both managers and owners play their parts in the same 'constellations of interest' which are dominant. Moreover, similarly and uses the term 'ruling class' to cover the economic, cultural and political 'bloc' created by the alliances arise between capitalist and middle-class managerial class interests. A part in this is inevitably played by interlocking company directorships whereby the 'pattern of meetings' which these involve are 'reinforced by a network of kinship and friendship'. The importance of kin networks is shown by Marceau's (1989) research on European business graduates. She demonstrates how the 'international business elite' which she sees emerging uses kin networks as sources of prestige, information and finance. Power, managerial careers, wealth ownership and prestige are a ll closely interlinked in practice. The British scholar Christopher Pollitt (1990) has given this question considerable thought and has done some valuable work that is especially instructive here. In a searching critique of managerialism and its influence on the British and American public services, he builds an intriguing argument that managerialism "needs to be understood as an ideology, and one with some concrete and immediate consequences" (xi). Pollitt asserts that managerialism consists of a set of beliefs, values, and ideas about the state of the world and how it should be. He identifies five core beliefs of managerialism. 1) "The main route to social progress now lies through the achievement of continuing increases in economically defined productivity." 2) "Such productivity increases will mainly come from the application of ever-more-sophisticated technologies. These

Argument and Persuasion essay Example | Topics and Well Written Essays - 1000 words

Argument and Persuasion - Essay Example The United States is influencing the rest of the world through its culture and products, but the United States is also influenced by the culture of other countries. The United States is composed of different ethnicities and religions – the Jews, the Christians, the Muslims, the Hindus, and the Buddhists, and these ethnicities and religions have been absorbed and assimilated by Americans as part of their own culture. Traditional practices in medicine have also been integrated into our practice because of the proven benefits that they have managed to bring forth to patients and our country in general. These traditional practices include acupuncture, acupressure, and some herbal medications (Andrzejczyk, p. 96). Mega-corporations from other countries have also managed to make good business here in the United States, including Toyota, Sony, and Mitsubishi. Feng Shui, a distinctly Chinese practice is also being applied in many homes and by many designers in the United States. Through these practices there has been a mutual global cultural exchange, making it possible for different countries to be in closer contact with each other and to be more in touch with other countries. According to the â€Å"One Ku (cool) Language for All,† (Andrzejczyk, p. 149) the use of English as a universal language has also made it possible for nations to relate and communicate with each other as traders and as businessmen. The shift in this globalized world and the use of English represents a more willing participation of countries as global players in the economy. The common language has also managed to make our world smaller and easier for people to embrace and conceptualize. Just as globalization brings forth benefits, it can also bring about negative consequences. Its negative consequences are on the effects of the culture in the country where it is introduced, especially when it does not share the culture of the home country of the product being

Analysis of Environmental Issues Essay Example | Topics and Well Written Essays - 500 words - 1

Analysis of Environmental Issues - Essay Example This has led to a rise in the processes of energy production. The mining and burning of coal account for a few processes which are used for the purpose of energy production. The impact of coal on the environment is an issue of environmental concern. It serves as a threat to the environment owing to the production of hazardous substances which tend to alter the normal environment as well as lay effects on the health of the individuals (Finkelman et al 1999; Hill 2010). The burning of coal takes place in houses for domestic purposes in third world countries where there is the unavailability of gas. This is accompanied by the use of coal as an energy source for industries across the world. The process of coal mining precedes the process of coal burning. It is the procedure used for the extraction of coal. The processes of coal mining, as well as the burning of coal, lead to the release of harmful substances into the environment. These include carbon dioxide, nitric oxide and sulfur diox ide which are all harmful to the environment (International Labour Office et al 1994). Coal mining should be a regulated process and the sites should be away from places where people reside. Strict regulations should also be followed in these areas to prevent exposure to individuals. Ash should be deposited in safe sites where they are away from the water reservoirs to prevent contamination.

Challenging disability Essay Example | Topics and Well Written Essays - 2250 words

Challenging disability - Essay Example The challenge which is presented is based on defining the idea of disability from a social perspective, as well as how this can change the perception of the abilities one has. Medical Model and Definitions of Disability The traditional perception of disability is one which is defined by the social capacities one has as well as the experiences which one goes through. According to Crow, the concept of disability is one which is limited, specifically because of the definition of disability that is interpreted within society. The main focus is that one who is disabled has gone through a personal tragedy, specifically which leads to disadvantages, oppression of opportunities and impairments that don’t allow for the same experiences of life to be a part of what one needs. The problem which occurs is one which is based on the medical model of disability, specifically which is interpreted in society as a social context which impairs one from life experiences (Crow, 1996). The definiti ons of disability are one which is defined specifically through a medical application. One who has impairment has a loss of psychological, physical or anatomical structures or functions. One who has a disability is restricted or has a lack of performance of activities, specifically which relates to an impairment. ... Crow shows that the medical model is one which doesn’t align with the social model, which creates the attitude that the individual who is suffering from impairment can’t overcome the difficulty or struggle. Instead, the impairment creates a lack or loss in all activities that one can do within a given environment (Crow, 1996). The main challenge which Crow shows with the concept of disability are that the social stigma surrounding a handicap means that an individual is incapable of everything. For instance, if one has impairment with hearing, then this leads to the inability of all functions both mentally and physically and eliminates the individual from activities that are within society. The experiences which one has differ from the social stigma which has arisen around the concept of disability. The assumptions that are made within society then create a stereotype of the experiences and ideals which are based around the handicapped and impaired. This leads to a belie f that the quality of life that one has who is impaired is limited in experience. However, those who are disabled may not have the limited experience or restrictions which others in society have labeled them with (Crow, 1996). Social Context of Disability The main stereotypes which are taken with the terms of disability are furthered by the ways in which society responds to the given labels which are created outside of medical terms. The first stigma which is created is one which leads to a sense of oppression. When one believes that an individual is disabled, then there is a perspective that this means all the functions and abilities of the individual are limited. The response is to oppress those who are in this state, such as not providing the same

The Effects of Technology On The Accounting Profession Essay

The Effects of Technology On The Accounting Profession - Essay Example Another useful technology is the automated manufacturing computer. With this form of technology, PCs gather and report data at the same time. The result is an operational data framework that completely incorporates producing with advertising and accounting information, expanding both the quality and timelessness of data (Warren, 1998). This definite data has been of importance in accounting, permitting the accountants to create action based costing frameworks. These new costing frameworks permit accountants to assign overhead more productively. These frameworks can likewise recognize non-value added expenses giving cost accountants a chance to change them to value added expenses (Warren, 1998).Another innovation that is having an incredible impact on the accountant profession is Wi-Fi innovation. Presently, accountants can be on the inverse sides of the nation and deal with the same issues without either being on same location due to the advances of Wi-Fi innovation. Accountants can transfer data and reports from anyplace in the country regardless of the length. Types of Software Used To Improve the Accounting ProcessesEnterprise Resource Planning (ERP) SystemsThis is software that incorporates distinctive divisions in the association into the same framework. This makes information accessible differently and backings exercises between the distinctive divisions. The data is made accessible through a typical focal database and imparted through practical ranges, for example (Laudon & Laudon,   2006).

Dream Job Research Paper Example | Topics and Well Written Essays - 1500 words

Dream Job - Research Paper Example There are various opportunities in different fields. All we need to do is focus on a specific post in a company and try to reach the position by dedication and a little smart work. My dream job is to become a production manager in a software industry. Being in a software industry I will have the opportunity to handle different projects that are helpful in modernization of technology. This assignment will discuss about a job description of a manager along with compensation, benefits and appraisal program in a software company. Most of the software companies in the world hire people with skills in programming and software testing. Being a production manager my responsibility will be to take over the challenges required in completion of a project successfully. A manager in a software company is responsible for selecting a project that can be completed by the team, explaining the details about the project, managing manpower and completion of the project in time. These are the key specifications that a manager needs to take care of while an on-going assignment. There are two major challenges for a manager in a software company. First is to select an appropriate project that the assigned team can handle. The project selected must be easy for the team members so that can complete it in time without any errors. The second most important challenge is to motivate the team members so that they do not take a leave between the crucial days. Lack of proper workforce can lead to delay of job which might not be accepted by a company. Hence these are the two major challenges to take care of being a manager of a software company. Another important responsibility of a manager is to communicate with the management about any threats his team may come across while handling an important assignment. It is a manager’s duty to balance and bridge the gap between employees and management

How Gazda Cars and Bomino Printing approach the management of their activities Essay Example for Free

How Gazda Cars and Bomino Printing approach the management of their activities Essay Advantages * Its Organised * Their pay is related to their performance, which will motivate them perform better. * Work is carried out in controlled environment. * Its seen as social which motivates workers. * Managers convey moral elite, trustworthy, broadly motivated to organise influence others. * Employees have more control of their work (live to work). * Take interesting staff giving feeling of involvement, security job satisfaction, related to high achievement Disadvantages * Scientific approach used (work to live). * Communication between workers is bad. Not approachable, no influence. * Managers defined as rational economic, primarily motivated by just money. * Being too nice to staff makes managers look weak. Managers need that power so everything is in control. * Staff can abuse their manager if their needs are not fulfilled, e.g., they can strike. People can respond to many different types of management strategies, but there is no single strategy that will work for all everyone all the time. Therefore, Gazda Cars should refer to Fielders Contingency Approach to management. This theory supports the view of the complex man- i.e. the motives that man has which changes over time and in different situations, can be seen as personal hierarchy. It defines situational favourability, or the ease of influencing followers as the combination of situational factors: leader-member relations, task structure, and position power. Fielder argued that leadership style was innate and that the above three situational factors determined whether task or relations oriented leadership was more appropriate. The main ideas about Contingency Theory are: 1. There is no universal or one best way to manage 2. The design of an organisations and its subsystems must fit with the environment 3. Effective organisations not only have a proper fit with the environment but also between its subsystems and 4. The needs of an organisation are better satisfied when it is properly designed and the management style is appropriate both to the tasks undertaken and the nature of the work group. The contingency approach opens the door for the possibility that leadership could be different in every situation (Saal and Knight, 1988). It provides a more realistic view of leadership by allowing for complexity and situational specificity of overall effectiveness. As organisations today are faced with continuing changes in technology, environment conditions, and internal processes, this approach can offer a more sophisticated understanding of the leadership process and emphasise the idea of flexible, adaptive leadership that may contribute to the success of a company. However, the various models in contingency theory have been criticised largely for the difficulty in testing the contingency variables selected since variables may affect each other or be influenced by a leader. The complexity of situational factors and various combinations of task and subordinate characteristics makes a single comprehensive test of the model impossible (Wagner and Hollenbeck, 1992). As it is entirely possible that different leaders in the same situation may reach different conclusions about the situation, which may in turn cause them to take very different actions, the practical use of this theory in business is quite limited. Gazdas Mechanistic Structure Bominos Organic Structure Operates in a competitive fast changing environment but is not seen as exiting or fun. They are separate departments for production, sales, marketing, research and development, data processing, accounts and human resource management. Each member has their own specific role. Obedience to superiors and loyalty to the organisation are assisted upon. This structure is old fashioned. The communication usually comes in the form of instructions decisions issued by superiors and the performance feed back requests for decisions sent from subordinates. Work is carried in a controlled environment. Control authority relationships are structured in a vertical hierarchy. Operates in a highly complex environment. Tasks are highly specialised. Employees are not clear on how their tasks contribute to accomplishing organisational objectives. Distributes inkjet laser printing systems, which is a fast moving product, economically productive. Department are separated for all the main business functions. General roles are defined for each member. Authority relationships control are structured in a network rather than a hierarchy. This approach is to do with being nice to staff. Commitment to organisational goals is recommended more then loyalty or obedience. Teams are set up to work on new product development. Tasks are modified often redefined by means mutual adjustment among task holders. Workers have a variety of tasks which are broad and independent. Relation of task performance to attainment of organisational objectives is emphasised. Gazdas Role culture Bominos Task culture There are usually job descriptions, rules procedures to govern behaviour as well as procedures for all activities. Pay is related to performance. A role culture is one which emphasises conformity to expectations. As Harrisons theory states, such organizations can be said to be rational instruments for the achievements of specific goals. People work most effectively efficiently when they have relatively, simple clearly defined, circumscribed measurable tasks. However the company operates in a highly complex fast changing environment. Here management is seen as completing a succession of projects or solving problems, often as a part of a team. It is project oriented, bringing together the right people. The staff get a feeling of involvement; security general job satisfaction are closely related to high achievement. Performance is judged by results. Job satisfaction tends to be high, to the degree of individual participating group identity. Though the current tall structure and Role culture at Gazda internally complement each other, one can question whether those are the most efficient with regards to the dynamic and highly competitive external environment. Role culture and tall structure is perfectly suited in a stable external environment but cannot maintain maximum productivity in an unpredictable and rapidly changing external environment. Such structures and cultures lack the flexibility to quickly adapt to external influences; it is commonly known that if one cannot adapt to ones external environment then one is in great danger of becoming extinct. It is important to identify the need for reorganisation culture, process and structure. If reorganisation can be justified than the most feasible and effective approach should be implemented to replace its predecessor. The structure at Gazda is a much closed system where information processing and co-operation are slow. It can be said communication is the way to success, hence in order to achieve maximum efficiency champion manufactures need to increase levels of cooperation and information processing to improve the internal environment. Maybe a more organic approach, being an open system which emphasis is placed in group actions; co-operation and team work should be integrated into the present structure and culture along with lateral relationships. The pre dominant advantages of integrating these two new elements are firstly, allowing direct contact between employees and those higher up the hierarchy, hence problems are addressed quicker and time is used efficiently both the current structure and culture will successfully take the business further. In contrast to a tall organisation, a flat organisation will have relatively few layers or just one layer of management. This means that the Chain of Command from top to bottom is short and the span of control is wide. Due to the small number of management layers, flat organisations are often small organisations similar to Bomino Printing. A task culture refers to a team based approach to complete a particular task. They are popular in todays modern business society where the organisation will establish particular project teams to complete a task to date. A task culture clearly offers some benefits. Employees feel motivated because they are empowered to make decisions within their team, they will also feel valued because they may have been selected within that team and given the responsibility to bring the task to a successful end. I say they are both related because the informal structure relates to a particular task carried out by particular groups of individuals working together this is of a similar nature to a task culture. Decision making at managerial levels is more efficient as fewer people need to be informed/included in this process. Thirdly, staff motivation is increased at higher levels of co-operation means employees are not constantly being given simple direct orders by managers. This has a boosting affect on morale and motivation. Last but not least with a free flow of information present, all departments can be encouraged to succumb to change, therefore enabling the organisation to respond to influential external factors. Bomino Printing should remain loyal to the present culture and structure because this will help them build and progress further in the future.

Piezo-resistive pressure sensor

Piezo-resistive pressure sensor Introduction: Sensor is defined to be a device that can be responded to any type of signal and can receive those signals. The physical property of sensor is that it can convert any input into electrical signals with in electronic circuits. A sensor does not function itself because it is such larger system and consist of many detectors, signal processors and memory devices. In every device sensor is placed in either intrinsic or extrinsic states. Sensors are of two kinds, one is passive that can directly generate electric signal and responds to external factors. Another is active sensors these needed some external power of excitation signal for operation of the device. Sensors can be classified into many ways according to the usage. The classification scheme arranged from simple to complex. Sensors are divided into physical, chemical and biological type. The physical sensors consist of thermoelectric, photoelectric, electro elastic, photo elastic and pressure sensors. Sensor is the one of the MEMS application. Among different types of physical sensors iam discussing in this essay about the Piezo-Resistive pressure sensors.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The Piezo-Resistive sensors are used to measure the strain on a silicon diaphragm. Piezo-Resistive sensor devices are widely used in bio-medical field. These types of sensors always need temperature sensors for calibrating the device. Piezo-Resistive pressure sensor is the commercial product that is successful in MEMS technology. For increase the progress in integrated circuits the sensors are combined with the Piezo-Resistive effect. These types of sensors are widely used in many applications like in pressure switches, pressure gauges and in automobile parts. In this essay in below the Piezo-Resistive pressure sensors physical principle, fabrication process and the design system and the applications of this type of sensors is explained. Physical principle: The Piezo-Resistive pressure sensor main principle is linearity and sensitivity. These two are the main principles involved in this type of sensor. Piezo-Resistive principle: An elastic material is taken and due to some source the strip of this material tends to move and if there is increase in longitudinal dimension then there will be decrease in lateral dimensions then cross section area will be decreased. If this is positive strain means there will be change in resistance value due to Piezo-Resistive effect. The pressure sensor consists of Silicon diaphragm, Piezo-Resistive in a wheat stone bridge and Silicon diaphragm is used to convert pressure into mechanical stress. The Piezo-Resistors converts stress into resistance and then finally resistivity changes into output voltage. Subsystems here are divided into pressure sensor with high sensitivity and good linearity and this entire setup. Linearity: Analysis of linearity begins with small deflection theories and deflections are small compared to thickness of diaphragm. If the error in linearity error is less than 0.3% then linearity error decreases as the length of resistivity changes. As the length of resistor increases then linearity error will be decreased. There are some steps to be followed in linearity. First the magnitude error must be lower than linearity error then shape of curves varies as the length of the materials changes. Then error moves from negative to positive applied pressure changes. In final step linearity error is no more symmetric and it will be irregular. If the diaphragm thickness increases then linearity error also reduces then error shifts from positive to negative sign. A best linearity error observed at a diaphragm with a thickness of 2.2 µm.The linearity error decreases if the thickness of diaphragm increases. When compared to linearity error in square and circular diaphragm means in ci rcular diaphragm occupies less area then square. Then large deflections are reduced in this case. Sensitivity: Sensitivity analysis is based on small deflection theories of plates. The pressure deflection relationship of plates is fabricated from isotropic and homogenous materials. The location and shape of resistors are also the effects of pressure sensors. Resistors are usually placed where there will be increase in stress larger to increase the sensitivity. The parameters are length L, width W, for the shape and the distance between in outer parallel resistor and the distance between in outer parallel resistor and diaphragm is 2dXt and distance between perpendicular resistor and diaphragm id dy.Sensitivity is approximated if all resistors are exactly same and have no Zero offset. In circular shape diaphragm the sensitivity is high at the edge and resistors are placed in radical directions. In top or bottom of diaphragm the sensitivity is high. Fabrication process: The pressure sensor chips are packaged individually for pre-moulded-housing packing techniques leading to low packaging throughout a large body. The packaging steps are shown in below and here top-down fabrication process takes place. A lithographic dam-ring approach is used to develop for fabricating the Piezo-Resistive pressure sensors. Initially a pressure sensor wafer with Pyrex glass combination is taken and the thickness of layer is up to 150 µm. The ultra thick layer of 150 µm with negative-tone positive resist is spin coated on the surface at a level up to 4inches. Then photolithography process is taken place to use dam-ring approach around the silicon membrane surface of the pressure surfaces. Then dicing process is used to separate the wafer and then splits into multiple pressure chips as observed. Then an adhesive material is placed on die pads on the substrate and then a dam-ring is then picked and placed on the die pads of organic substrate. Then it is heated to cross link the adhesive material and it will combine both pressure sensor and organic substrate. Then a wire bonding takes place between the aluminium bonding pads of the pressure sensors and the electrode pads of organic substrate. Then organic panel substrate is attached with pressure sensors and placed into a transfer molding and encapsulate the pressure sensors and organic panel substrate. Because the top surface is moulded with inner wall surface in a closed position then inner space of dam-ring is not fulfilled by the fluid epoxy moling compound (EMC) during molding process. Finally a pressure with a sensing channel space is separated from the organic substrate by using a saw machine after the EMC process. Dam-ring deposition: In photo resist model to achieve a wide operation window a specific coating thickness is required. For this high film thickness a photo resist with high viscosity is taken. A spin wafer and a hot plate are used for spin coating process of the dam-ring material. To produce a ultra thick sacrifice layer a two stage spin coating process is employed. Lithographic process is introduced to achieve a double layer of photo resist in dam-ring method. Transfer molding:As the pressure sensor is attached to organic substrate then substrate is placed in a transfer molding.To reduce the wrapage of encapsulated product the molding compound must be carefully chosen so that thermal expansion is close to that of organic substrate. To eliminate the wrapping of organic panel substrate a low molding temperature of 165 ° is utilized. The silicon membrane of pressure sensor and pressure loading of environment is reserved by the dam-ring. Design of the system: The majority available of micro-machined pressure sensors are bulk micro-machined Piezo-resistive devices. The Piezo-resistors are arranged in such a way by selectively doping portions of the diaphragm to form junction-isolated resistors. In an anisotropic material in silicon is defined by a tensor that relates the three directional components of the electric field to the three directional components of current flow. In a tensor general it has nine elements and expresses in a 3*3 matrix as they reduce to six independent values. Where Ei and Ji are electric field and current density components and ?i is the resistivity component. If the Cartesian axis is aligned to the (100) axes in a cubic crystal structure then Ï 1, Ï 2, Ï 3 are equal along the (100) axes denoted by Ï .The remaining components of matrix and then cross axis resistivitys will be zero due to unstressed silicon is electrically isotropic. Finally the change in the components in the matrix leads to six stress components by a 36 element tensor. This tensor is finally populated by three non-zero components as shown in below. Here ÃŽ  IJ co-efficient have units of Pa-1 and this can be either positive or negative. The ÃŽ  11 have the resistivity in any direction to stress in same directions. The equation (1) is derived along the (100) co-ordinate axes and convenient to apply. The fractional change is represented as ΔR/R = ÃŽ  LÏÆ'L+ÃŽ  TÏÆ'T. Where ÃŽ  L and ÏÆ'L are Piezo-resitive co-efficient and these are parallel to the direction of current flow and ÃŽ  t and ÏÆ't are values in transverse direction. Combining the equations by using a transformation of the co-ordinate system in (100) axes the equations can be stated as ÃŽ  L = ÃŽ  11+2(ÃŽ  44+ÃŽ  12-ÃŽ  11) * (L12m12+L12n12+n12m12) ÃŽ  t = ÃŽ  12-(ÃŽ  44+ÃŽ  12-ÃŽ  11) * (L12L22+m12m22+n12n22) Where L1, m1, n1 are the directions cosines of a vector that are parallel to the current flow and L2,m2,n2 are unit length vector perpendicular to the resistor. By combining and neglecting terms in above two equations (2 3) the Piezo-Resitive co-efficient is varied with doping level and operating temperature then p-type is placed in equation(4). ÃŽ   (N, T) =P (N, T) ÃŽ  ref. The longitudinal and transverse Piezo-resitive co-efficient in the surface of a (100) silicon wafer is observed. Observe that each figure in silicon wafer (100) splits into two halves as ÃŽ  L ÃŽ  t for both p-type and n-type in silicon. Then for p-type silicon both ÃŽ  L ÃŽ  t the peak is along (100) and for n-type silicon also peak is along (100).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  If the length of resistor decreases means then resistance also decreases then increase in power consumption is not favourable. If the width decreases then variations are observed along the non-ideal lithography. From the above it concludes that size of diaphragm reduces as the resistor have a large area between its perimeter and the centre. Advantages of Piezo-Resistive pressure sensors:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  At present today pressure sensors are used in a variety of applications in industries in overall MEMS market.Piezo electrical is used to measure high pressure with a diaphragm and widely used highly in pressure sensors. Piezo-Resistive force sensors have high applications that are fabricated using MEMS processes. The Piezo-Resistive pressure sensors are used for direct mounting on printed circuit boards. Piezo-Resistive are used to measure the cell consists of a glass back plate and the silicon chip with diffused resistor bridge. Main Piezo-Resistive pressure sensors applications are: It is used in barometric, small airplanes and used in robotic, sanitary and meteorology, air conditioning. These are used to improve sensitive, small size and are less in cost. Mainly some silicon sensors that use Piezo-Resistivity effect use a four element Wheatstone bridge configuration. Piezo-Resistive pressure sensors are low in cost and having small size and these have high resolution and have high sensitivity. Use of this element also removes four resistors that form during wheat stone bridge design. A cost effective current mode circuit is used to operate with a single Piezo-Resistive element. Ultra miniaturized 0.69 French Piezo-Resistive pressure sensors are designed for fabrication in bio-medical applications. These ultra-miniaturized Piezo-Resistive pressure sensors have many users in biomedical fields like in intra cranial pressure monitoring during nano-surgery. And also used for air monitoring in respiratory diseases, observing the blood pressure during surgery then for monitoring obstetrics and used for monitoring the urinary pressure in diagnosis for respective disorders.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The continuous development is reducing the catheter size leads to develop in ultra-miniaturized pressure sensors. The micro-maching technology in both industrial and automotive pressure sensors is very good. Due to these factors Piezo-Resistive sensors have some advantages. Like it has high tensile strength, it is low cost and has high elasticity also have good elastic properties and compatible in microcircuit technology. Pressure sensors and accelerometers both of these use Piezo-Resistive sensors with piezo electric effect. These Piezo-Resistive sensors also used in automotive applications it has up to now 40 applications in future they can be increased.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  For controlling the engine some sensors are used for controlling the engine and some are used as for good fuel economy and for controlling the engine. Accelerometers here are used for anti-skid braking, air bags and also in case of antiskid braking. Many transmissions are continuously developed that requires use of sensors and electronics to optimize transmission rations and power demand. These type of pressure sensors are also used in various industrial applications such as automobiles and also in biomedical applications. Pressure sensors are used in measurement of mechanical quantities like force, stress and other. Then biomedical applications are used to measure the control flow of blood pressure and force generated within heart cells. In capacitive sensors it has major problems in massive commercialization is sealing of capacitive cavity and the electrical lead transfer between vacuum-sealed cavity and outside world. To overcome this problem recently piezo resistive sensors are invented and these became major choice.To overcome so many number of difficulties these type of sensors are used.A nano crystalline silicon is used to achieve a high sensitive has been proposed. The silicon piezo resitive pressure sensors are used to increase the sensitivity by introducing stress in regions in the formation of elliptical holes.For continous monitoring on operational temperature and for signal to noise ratio the piezoresistor is taken into account.In biomedical applications the addition of sensitivity and temperature effect and the signal to noise ratio should laso be considered in order of design the system. The piezo resitive pressure sensor represents has one of MEMS applications that used in domestic appliances and used in various applications like laundary,washing machines and in vaccum cleaners.Differntial pressure sensors are used to measure the pressure difference in between two environments. Silicon has excellent properties in piezo resistive material as it changes the bulk resistivity when stress is apllied. For manufacturing new devices like electronic devices and maintaining high yield level is a challenge task that depends used for identifying the mechanism.Electronic sensors are mainly used in industrial automotion applications.Due to direct connection and profitability the manufacturing of yield is important.As is yield is 100% means it constantly improving the techniques. In all aircrafts pressure sensors are used in engine,fuel,hydraulics and in enviromental applications.By using these type of piezo resistive sensors increase in demand on weight,size,cost and in signal processing.These type of piezo-electric resitive sensors are used to built a small size,light weight and the low cost of value. These are the advantages of Piezo-Resistive pressure sensor that gives an idea why this sensor is more effective than compared to other sensors and why this type of Piezo-resistive pressure sensors are used. Conclusion: Sensors are been developed from past 20 years and widely been used in industrial and in biomedical. These sensors also offers a many type of sensors among them magnetic sensor are one type. By observing all the factors in above we can conclude that Piezo-Resistive pressure sensor is one type of sensor that have excellent properties in electrical and this sensor is fabricated in a very small size. The Piezo-Resistive pressure sensor has many advantages that mentioned in above essay. The fabrication process, main principle involved and the Design of the system of Piezo-Resistive pressure sensor is explained above. The output voltage of this Piezo-Resistive pressure sensor is small in magnitude. So due to this the output must be amplified to increase the S/N ratio and provides an output that is used in microprocessor system.Fianlly an Piezo-Resistive pressure sensor with an high output voltage with low fabrication cost must been developed.
