Animals vs. Humans in Medical Experimentation Essay

For centuries mankind has experimented on animals for a number of different reasons. Early experimentation with animals was originally born out of curiosity but eventually became a necessity to find medicines to cure viruses and a myriad of illnesses. If not for the existence of animals, humans would be left to experiment on themselves at a high rate which would create a worldwide moral dilemma. Such a dilemma could be dictated based on the question of who should be chosen for experimentation; should it be a particular race or class of people? Animals commonly used in medical research are rats and chimpanzees. Over time these species have proven to be plentiful and they have exhibited the ability to sustain the various testing†¦show more content†¦Thanks to animal research, many diseases that once killed millions of people are now either treatable or curable. Animal testing has not only benefit humans, but animals as well. Some animal testing has lead to life saving and life extending treatments for many of the animals used for testing. A complete alternative to animal testing has yet to be discovered. The focus of animal research has been characterized by three criteria, The Three R’s. â€Å"’The Three Rs’ are reduction, replacement and refinement. Here in the US, research communities are committed to supporting techniques that reduce the number of higher species used, replace animals with other models wherever/whenever possible, and refine tests to ensure the most humane conditions possi ble.† (Trull 2). Scientists try to keep the animals from being harmed as much as possible. Every research laboratory is required to have an Institutional Animal Care and Use Committee, consisting of research experts, licensed vets and members of the public. This committee is in charge of reviewing and accepting the use of animals. They are also in charge of watching the care and use of those animals by studying the laboratories, keeping track of the programs and responding to any additional concerns.

External Reporting Incentives or Standards

Question: Discuss about the External Reporting for Incentives or Standards. Answer: Effects of Changes in the Financial Reporting Environment Financial reporting environment refers to the rules, policies and standards of financial reporting. In the recent past, many changes have taken place in the financial reporting environment and the effects of the changes in financial reporting environment can be clearly identified in the business world. Christensen et al. (2015) believe that the changes in financial reporting have made several improvements in the reporting standards like, more transparency, more accuracy in the measurements of the value of assets and liabilities. However, on the contrary, Leuz and Wysocki (2016) noted that due to the changes in financial reporting, several technical issues have taken place. The major technical issue that has taken place is the new accounting standards. For example, as per the new standards provided by Financial Accounting Standards Boards (FASB) and Australian Accounting Standards Board (AASB), using the fair value method is essential while measuring the values of assets. However, using the fair value method does not provide any extra monetary benefit at the time of selling the assets because the assets are already measured at their current market price. On the other side, the changes in the exposure draft have created some confusion in the accountants of the companies. Many accountants cannot properly understand the actual requirements of new exposure draft provided by International Accounting Standard Board (Christensen et al. 2015). Financial reporting becomes more challenging for the companies. For example, in the new exposure draft, it has been mentioned that financial reports of the companies must include only the material information and immaterial information can decrease the usefulness of financial reports. Now, including all the material information is very difficult for the companies because sometimes for the future security companies need to keep some material information in secret. The changed environment of financial reporting in Australia is regulated by the International Accounting Standard Board (IASB), AASB and IFRS. As per the new guidelines and amendments provided by IFRS and FASB, it is mandatory for the companies to maintain the full disclosure principle during financial reporting. At the same time, the IFRS also mandated that while measuring the values of assets and liabilities, the companies need to follow the fair value method (IFRS.com, 2016). As per the AASB 101, the companies are divided into two tiers. The companies under tier 1, need to disclose all the material information in their financial reporting. However, the companies under tire 2 get some reduction in the disclosure requirements. As per AASB 132, the entities, which do not have equity capital, may have to adapt the presentation of the financial statements for the interests of the unit holders or members. As per AASB 116 and AASB 138, the changes in the values of plant and equipments and intangible assets are needed to be considered while ascertaining the comprehensive income (Aasb.gov.au, 2016). At the same time, the AASB 119 and AASB 121 have suggested to consider the employee benefits and changes in the foreign exchange rates at the time of determining the comprehensive income. The AASB and IASB have mentioned that the purpose of financial reporting is to represent the actual financial position and performance of the companies to their stakeholders and the other users in order to help them in taking economic decisions. Therefore, to comply with the new financial reporting environment, the companies need to adopt many changes in the financial reporting standards (Aasb.gov.au, 2016). However, the success or failure of the new accounting standards is influenced by the political activities. Here, the political activities do not refer to the activities done by the political parties, but it indicates the corporate governance of the companies. In order to get success in the business, it is essential to have strong corporate governance within the companies. However, the new accounting standards or financial reporting environment sometimes fails to identify the loopholes in the corporate governance in the companies and the case of Parmalat or Enron is the perfect example of that (Cblr.columbia.edu, 2016). The accounting regulations in Europe are considered as the strictest regulations in the world. However, the accounting regulations in Europe also failed to identify the corporate frauds the by the company. The company did the financial reporting in such a way so that nobody can understand the fraud. This type of political or corporate governance issue indicates that the accounting standards or financial reporting environment must provide some stricter guidelines to control the political influences and improve the financial reporting environment (Leuz Wysocki, 2016).

Pauls Case By Willa Cather Essays - Willa Cather, Pauls Case, Cather

Paul's Case by Willa Cather ?Paul's Case? A Symbolic Perception Imagine being entrapped in a life that you did not feel you belonged in. That is the story of Paul in ?Paul's Case,? written by Willa Cather. He lived in a suburban home where everyone seemed the same and there was a feeling of despair. Paul, who was a young man, felt that his father, teachers and classmates misunderstood him and therefore were unworthy of his company. In the story there are many symbolic elements. Flowers, for instance, symbolize Paul's personality and life. The parallel between the boy and the flowers is made by the author many times throughout the short story. In the beginning of the story Paul has a meeting with the teachers of his school because he was misbehaving. For the meeting Paul shows up wearing ?clothes [that] were a trifle outgrown . . . [with] a red carnation in his buttonhole? (49). This shows his total disrespect for authority because he is going to get disciplined; and the teachers thought this ?was not properly significant of the contrite spirit befitting a boy under the ban of suspension? (49).? The flower he wore shows that he does not care about school or his teachers: his teachers felt ?that his whole attitude was symbolized by his shrug and his flippantly red carnation flower? (50). The principal also noted his conceit as he left the meeting and bowed which was described to be ?a repetition of the scandalous red carnation? (51). It is almost as if the flower is his strength and reminds him of his need to be with a different class of people. Paul worked as an usher at Carnegie Hall. This was the only place where he really felt himself unfold. He became lost in the music, plays, and art. While Paul was at home, he would dream about the life he believed himself to be living as ?a morbid desire for cool things and soft lights and fresh flowers? (55). To Paul, people who enjoyed having the presence of flowers seemed to be of a higher class above the rest. That is why he always wore a flower. He describes his neighbourhood, the people he despises to be, ?prosy men who never wore frock coats, or violets in their buttonholes (pg. 60).? He would dream about, ?the flowers he sent (pg. 60),? to members of the stock company who were his ?acquaintances.? Paul wants to be as the flowers, living to all of their extent, saturating in the beauty of life. While Paul was in New York City one of the first things he did was ?[ring] for the bell boy [to send] him down flowers? (62). He was living out his dreams. He was pleased with his surroundings and his style of living during his days in New York and expressed his ?dearest pleasure [was] . . . his enjoyment of his flowers? (66), and goes on to say that he couldn't remember a time of such bliss. He loved all forms of creative expression and was intrigued by, ?whole flower gardens blooming behind glass windows, against which the snowflakes stuck and melted; violets, roses, carnations, lilies of the valley-somehow vastly more lovely and alluring that they blossomed thus unnaturally in the snow.? (64) The flowers induce a happiness in Paul at the time of his greatest revolution. During the last days of his stay in New York, Paul feels that his status is becoming dead and useless as his money runs out. He begins to die inside as with his authority shown by the violets he wears in his buttonhole. Paul expresses the symbolism between his life and the flowers:

Violence and Television essays

Violence and Television essays Boink! Boom! Crack! The sounds of the fight scene rage on. Many have fallen in this particularly bloody battle. The good guys have taken their losses but struggle on to what is seemingly a victory. Their aggression is fierce and helps them. Fires consume the background; men and women lie on the ground in pain. Even if it werent for the bombs, missiles, bullets, etc. that are flying around, hand-to-hand combat would have got the better of them. It was a classic battle scene when looking back at it, a true testament of blood, hell, and gore. This may sound like a heroic made-for-TV movie shown only on primetime in the hopes of recruiting a mature audience. But it is not. In fact, it is just another Saturday-morning special of GI Joe, The Real American Hero, that I watched with my brother and cousins. We were religious followers of the show, tuning in every week to see how Sergeant Slaughter, Duke and the rest of the gang would handle the likes of King Cobra and his cronies. GI Joes early morning time slot encouraged kids, like us, to tune in every weekend. While eating our CheeriosTM and Frosted FlakesTM we got a dose of some real fightin action, in excess of fifty violent scenes for the morning: there is more than enough to fill the appetite. The truth is, violence on television is on every single day. It takes its toll on society, especially children. The damage done by violence on television is detrimental and confirmed by statistics, case studies, and personal experiences. Fistfights, shootouts, car crashes, rapes... Take your pick. Violence is everywhere on television, sometimes gory and gruesome, other times clean and remote. It is not just the Saturday morning cartoons; clips from action-adventure series, the nightly news and MTV are interwoven with violence and extremely mature content. Prime-time programs can average eight hostile acts per hour; children's shows four t...

Inclusional Best Practices, Supporting Inclusion

Inclusional Best Practices, Supporting Inclusion The inclusive classroom means that all students have the right to feel safe, supported and included at school and in the regular classroom as much as possible. There is ongoing debate about placing students completely in the regular classroom. Views from both parents and educators can create a great deal of anxiety and passion. However, most students today are placed in agreement with both parents and educators. Often, the placement will be the regular classroom as much as possible with some cases where alternatives are selected. The Individuals With Disabilities Education Act (IDEA), amended version 2004, does not actually list the word inclusion. The law actually requires that children with disabilities be educated in the least restrictive environment appropriate† to meet their â€Å"unique needs.† The least restrictive environment typically means placement in the regular education classroom which typically means Inclusion when ever possible. IDEA also recognizes that it is not always possible or beneficial for some students. Here are some best practices to ensure inclusion is successful: An Overview of the Inclusive ClassroomIn the inclusive classroom, it is important that the teacher fully understands the learning, social and physical needs of the students. A teacher has a special role to play when trying to maximize learning potential for students with special needs. It becomes the educators role to create a welcoming environment and provide students with ongoing opportunities to learn, share, and engage in all classroom activities. Determining what alternate assessment needs to occur is another area where the educator needs to make changes to specifically support the student in the regular classroom. Preparing Students for the Inclusive ClassroomThis checklist helps both parent and teacher prepare the student for the inclusional classroom setting. The child needs to know what to expect, equally important is to ensure that there are no surprises.The Inclusional Classroom ChecklistI am a big fan of checklists. This checklist provides educators with guidance about m aximizing success for students in an inclusional setting. There are 12 key items that will guide the establishment of a successful inclusional setting. Each item points to some form of action which will be key in maximizing sucess for the student with special needs. Youll find that the checklist includes strategies for academic, social and physical success. Using Peer Support in the Inclusive ClassroomPeer support is one of the most essential ingredients in the inclusive classroom setting. Peer support helps to build rapport and a sense of belonging and community among students. Students with special needs often become the targets for inappropriate behavioral conduct from other students, however, by education the whole class and having members of the class become peer supporters, the problem of teasing is often minimized. How To Reach and Teach all Students in the Inclusive ClassroomIt always helps to have great resources to help out. Without a doubt, this resource is my favorite! The pages of my book are dog-eared, marked up and highlighted. I have come across and read many books and articles about inclusion but this book is the practical one that my colleagues all agree on as needing at their fingertips. Some food for thought regarding some of the challenges of the full inclusional model include: How can you ensure that the student relationsips in your class are not superfical?How will you provide intense one to one instruction? Time for this is often greatly reduced.How will you ensure that equal rights are in place for all students?Sometimes youll be faced with research that suggests the inclusional classroom may not be as successful based on the specific needs of the student.Many parents want both inclusion and alternative settings. Sometimes the full inclusional model just wont support all the needs. Although inclusion is the preferred approach, it is recognized that for a number of students, it is not only challenging but sometimes controversial. If you are a special education teacher, there is no doubt that you have discovered some of the challenges of inclusion.

Pertussis or Whooping Cough Research Paper Example | Topics and Well Written Essays - 1000 words

Pertussis or Whooping Cough - Research Paper Example The present research has identified that there are two types of pertussis: severe and mild. Severe pertussis occurs in the infants and young children. Severe pertussis is more complicated and may lead even to death, whereas, mild pertussis is hard to diagnose and it is mostly misunderstood for the common cold. Bordetella pertussis  was first isolated in pure culture in 1906 by Bordet and Gengou. B.pertussis is a small, gram-negative, aerobic coccobacillus of 0.8 ?m by 0.4 ?m. It is arranged singly or in small groups. They also have pili-like filaments and are non-motile. B.pertussis is the most fastidious bacteria. It is transmitted from a person – to – person through aerosolized droplets. B.pertussis causes respiratory tract infection in humans and warm-blooded animals. The incubation period of this bacterium is 7-10 days. The bacterial cells â€Å"colonize only the ciliated cells of the respiratory mucosa.† After the onset of the infection, the cells colonize in the mucosal membrane of the respiratory tract. The attachment of the B.pertussis occurs with the help of a pertussis toxin produced by the bacterium. The filaments those are present in the bacteria acts as a bridge between the bacterium and the ciliary receptor This pertussis toxin is highly toxic and has a number of virulent factors. The adjuvant effect of pertussis toxin on the human body results in lymphocytosis and hypoglycemia within 3 hours in the ciliated epithelial cells and also causes ciliostasis. The adenylate cyclase toxin and tracheal cytotoxin combine with pertussis toxin to cause ciliostasis. The same toxins inhibit the phagocytic activities of the host. The phagocytic activities include chemotaxis, engulfment, the oxidative burst, and bactericidal killing. The adenylate cyclase is a hemolysin that causes lysis of the red blood cells. The tracheal cytotoxin stops the beating mechanism of the ciliated cells. This toxin then kills the ciliated cells and extrudes it from the mucosa. It also stimulates the release of the Interleukin – I, thus causing fever. The first stage symptoms of pertussis are a cough, low –grade fever, running nose, sneezing, etc. After 7 – 10 days, the nasal discharge gets thickened and the cough also gets severe. This leads to severe upper respiratory congestion in infants. This is the second stage. It lasts for 1-2 weeks. The third stage is the more complicated stage. The coughing increases very heavily that the child will cough more than 5 times during a single respiration and have a sudden intake of air, causing a whooping sound. The sound is caused due to the narrowed glottis. At this stage vomiting, weight loss, tongue protruding, eyes bulging are most common. Pneumonia, the serious complication of pertussis, results in the 90% of the deaths in children under the age of 3. The infection of the bacterium causes substantial immunity. This substantial immunity lasts for many years. The second infec tions are more frequent in adults and are usually not severe. The infants and children are highly prone to the lethality of this disease. The children who are suffering from a whooping cough are prone to pneumonia.

Advantages and disadvantages of team and individual teaching Article

Advantages and disadvantages of team and individual teaching - Article Example Teaching in a team actually means a group of teachers, decisively working with each other on regular basis to facilitate students in groups in order to acquire knowledge about various subjects. The instructors in team teaching cooperate with one another and make use of the particular skills and abilities of each instructor. This approach of teaching boosts up the student-teacher interaction, allowing both of them to evaluate each other. Contradictory to individual teaching, the goals are set by the consensus of team members and the methods and strategies of teaching are also set by the line of reasoning among the group members, helping to bring about the best of it. (Judson T Shaplin; Henry F Olds, 1964) The students may learn more profoundly by team teaching approach as more than one experts of the very topic defines it with a different approach. It helps to understand the topic from various frames of references. This approach helps to get rid of students-teacher personality problems. Presence of another team mate abates the yoke of work from the teachers and motivates them more towards their profession. Team working distributes the responsibility, encourages creativity, and brings effectiveness in teaching. (Medill Bair; Richard G Woodward, 1964) However, sometimes this approach is not adapted by the experts. Since, groups are not every time as good as we assume them to be. Often, teachers do not prefer to teach in teams, due to different reasons.

Quality Control includes general methods such as accuracy  checks on data acquisition and calculation and the use of  approved standardised procedure for emission calculations,   measurements, estimating uncertainites, archiving  informations and reporting. Quality Control (QC)Qc is a process that is use to Find Bug  From The Product , as early as possible amp; make sure they  get Fixed   Quality control is a process in which sudden checkings are  conducted on the roles   Quality Control :- QC is evaluating the product,identifying the defects and suggesting improvements for the same. It is oriented towards Detection eg:Testing. What are 8 principles of total quality management and key benefits the eight principles of TQM: 1. quality can and must be manage 2. everyone has a customer to delight 3. processes, not the people, are the problem 4. very employee is responsible for quality 5. problems must be prevented, not just fixed 6. quality must be measured so it can be controlled 7. quality improvements must be continuos 8. quality goals must be base on customer requirements. The concept of TQM (Total Quality Management) Total Quality Management is a management approach that originated in the 1950s and has steadily become more po pular since the early 1980s. Total Quality is a description of the culture, attitude and organization of a company that strives to provide customers with products and services that satisfy their needs. The culture requires quality in all aspects of the companys operations, with processes being done right the first time and defects and waste eradicated from operations. Total Quality Management, TQM, is a method by which management and employees can become involved in the continuous improvement of the production of goods and services. It is a combination of quality and management tools aimed at increasing business and reducing losses due to wasteful practices. Some of the companies who have implemented TQM include Ford Motor Company, Phillips Semiconductor, SGL Carbon, Motorola and Toyota Motor Company. TQM Defined TQM is a management philosophy that seeks to integrate all organizational functions (marketing, finance, design, engineering, and production, customer service, etc. ) to focus on meeting customer needs and organizational objectives. TQM views an organization as a collection of processes. It maintains that organizations must strive to continuously improve these processes by incorporating the knowledge and experiences of workers. The simple objective of TQM is Do the right things, right the first time, every time. TQM is infinitely variable and adaptable. Although originally applied to manufacturing operations, and for a number of years only used in that area, TQM is now becoming recognized as a generic management tool, just as applicable in service and public sector organizations. There are a number of evolutionary strands, with different sectors creating their own versions from the common ancestor. TQM is the foundation for activities, hich include: * Commitment by senior management and all employees * Meeting customer requirements * Reducing development cycle times * Just In Time/Demand Flow Manufacturing * Improvement teams Reducing product and service costs * Systems to facilitate improvement * Line Management ownership * Employee involvement and empowerment * Recognition and celebration * Challenging quantified goals and benchmarking * Focus on processes / improvement plans * Specific incorporation in strategic planning This shows that TQM must be practiced in all activities, by all personnel, in Manufacturing, Marketing, Engine ering, R;amp;D, Sales, Purchasing, HR, etc. The core of TQM is the customer-supplier interfaces, both externally and internally, and at each interface lie a number of processes. This core must be surrounded by commitment to quality, communication of the quality message, and recognition of the need to change the culture of the organization to create total quality. These are the foundations of TQM, and they are supported by the key management functions of people, processes and systems in the organization. Difference between Product Quality and Process Quality 1. Product quality means we concentrate always final quality but in case of process quality we set the process parameterProduct quality means we concentrate quality of product that is fit for intended use and as per customer requirement. In the case of process quality we control our rejection rate such that in-house rejection is at minimum level. | | 2. Product quality means we concentrate always final quality but in case of process quality we set the process parameter 3. Product quality is the quality of the final product made. While Process quality means the quality of every process involved in the manufacturing of the final product. 4. Product quality  is focusing on meeting tolerances in the end result of the manufacturing activities. The end result is measured on a standard of good enough. Process quality focuses on each activity and forces the activities to achieve  maximum tolerances  irrespective of the end result. Something like a paint can manufacturer, the can and the lid need to match. A product quality focus on whether the paint can and lid fit tight enough but not too tight. This focus would require cans to be inspected and a specific ratio of defective would be expected. Process quality, the can making activities would be evaluated on its ability to to make the can opening exactly 6. 000 inches. The lid making would be evaluated on its ability to make  lids  6. 10 inches. No cans would be defective if the distribution of output sizes is narrow enough. The goal of process quality is to force narrow variance in product output to be able to expect close tolerances. This focus on process quality typically generates higher product quality as a secondary outcome. 5. When we talk about software quality assurance, we often discuss process measurements, proces s improvements, productivity increase, quality improvement etc. And when we talk about quality improvement, mostly people think about product quality improvement. Most of the time people forget about process quality improvement. In fact, people find it difficult to differentiate between product quality and process quality. Let us find out the difference! During software development we have work products like requirement specifications, software design, software code, user documentation, etc. Quality of any of these work products can be done by measuring its attributes and finding of they are good enough. For instance, a requirement specification may be ambiguous or even wrong. In that case, quality of that requirement specification is bad. So during quality assurance audit (peer review, inspection etc. ), this defect can be caught so that it can be rectified. During software development project, a lot of processes are followed. The top processes are the project processes like project initiation, project planning, project monitoring, and project closure. Then we have development processes like  requirement development, software design, software coding, software testing and software release. All of these processes are not executed perfectly on any project. Improvement in these processes can be achieved if we have audits of these processes. For instance, these audits are done by using standards like CMM (Capability Maturity Model). These standards dictate as to how any project or development process needs to be executed on any project. If any process step is deviating too much from these standards then that process step needs to be improved. The most important job of any software quality assurance department is to audit and ensure that all processes on projects being executed in that organization adhere to these standards and so quality of these processes (project amp; development) is good enough. Effect of ISO on Society Society ISO standards help governments, civil society and the business world translate societal aspirations, such as for social responsibility, health, and safe food and water, into concrete realizations. In so doing, they support the United Nations’ Millennium Development Goals. Social responsibility 1 November 2010 saw the publication of ISO 26000 which gives organizations guidance on social responsibility, with the objective of sustainability. The standard was eagerly awaited, as shown by the fact that a mere four months after its publication, a Google search resulted in nearly five million references to the standard. This indicates there is a global expectation for organizations in both public and private sectors to be responsible for their actions, to be transparent, and behave in an ethical manner. ISO 26000, developed with the engagement of experts from 99 countries, the majority from developing economies, and more than 40 international  organizations, will help move from good intentions about social responsibility to effective action. Health ISO offers more than 1 400 standards for facilitating and improving health-care. These are developed within 19 ISO technical committees addressing specific aspects of healthcare that bring together health practitioners and experts from government, industry and other stakeholder categories. Some of the topics addressed include health informatics, laboratory equipment and testing, medical devices and their evaluation, dentistry, sterilization of healthcare products, implants for surgery, biological evaluation, mechanical contraceptives, prosthetics and orthotics, quality management and protecting patient data. They provide benefits for researchers, manufacturers, regulators, health-care professionals, and, most important of all, for patients. The World Health Organization is a major stakeholder in this work, holding liaison status with 61 of ISO’s health-related technical committees (TCs) or subcommittees (SCs). Food There are some 1 000 ISO food-related standards benefitting producers and manufacturers,  regulators and testing laboratories, packaging and transport companies, merchants and retailers, and the end consumer. In recent years, there has been strong emphasis on standards to ensure safe food supply chains. At the end of 2010, five years after the publication of ISO 22000, the standard was being implemented by users in 138 countries. At least 18 630 certificates of conformity attesting that food safety management systems were being implemented according to the requirements of the standard, had been issued by the end of 2010, an increase of 34 % over the previous year. The level of inter-governmental interest in ISO’s food standards is shown by the fact that the UN’s Food and Agriculture Organizations has liaison status with 41 ISO TCs or SCs. Water The goals of safe water and improved sanitation are ingrained in the UN Millennium Development Goals. ISO is contributing through the development of standards for both drinking water and wastewater services and for water quality. Related areas addressed by ISO include irrigation systems and plastic piping through which water flows. In all, ISO has developed more than 550 water-related standards. A major partner in standards for water quality is the United Nations Environment Programme. The Waterfall Model was first Process Model to be introduced. It is also referred to as a  linear-sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase must be completed fully before the next phase can begin. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. In waterfall model phases do not overlap. Diagram of Waterfall-model: Advantages of waterfall model: * Simple and easy to understand and use. * Easy to manage due to the rigidity of the model – each phase has specific deliverables and a review process. Phases are processed and completed one at a time. * Works well for smaller projects where requirements are very well understood. Disadvantages of waterfall model: * Once an application is in the  testing  stage, it is very difficult to go back and change something that was not well-thought out in the concept stage. * No working software is produced until late during the life cycle. * High amounts of risk and uncertainty. * Not a good model for complex and object-oriented projects. * Poor model for long and ongoing projects. Not suitable for the projects where requirements are at a moderate to high risk of changing. When to use the waterfall model: * Requirements are very well known, clear and fixed. * Product definition is stable. * Technology is understood. * There are no ambiguous requirements * Ample resources with required expertise are available freely * The project is short. The basic idea here is that instead of freezing the requirements before a design or coding can proceed, a throwaway prototype is built to understand the requirements. This prototype is developed based on the currently known requirements. By using this prototype, the client can get an â€Å"actual feel† of the system, since the interactions with prototype can enable the client to better understand the requirements of the desired system. Prototyping is an attractive idea for complicated and large systems for which there is no manual process or existing system to help determining the requirements. The prototype are usually not complete systems and many of the details are not built in the prototype. The goal is to provide a system with overall functionality. Diagram of Prototype model: Advantages of Prototype model: Users are actively involved in the development * Since in this methodology a working model of the system is provided, the users get a better understanding of the system being developed. * Errors can be detected much earlier. * Quicker user feedback is available leading to better solutions. * Missing functionality can be identified easily * Confusing or difficult functions can be identified Requirements validation, Quick implementation of, incomplete, but functional, application. Disadvantages of Prototype model: * Leads to implementing and then repairing way of building systems. Practically, this methodology may increase the complexity of the system as scope of the system may expand beyond original plans. * Incomplete application may cause application not to be used as the full system was designed Incomplete or inadequate problem analysis. When to use Prototype model: * Prototype model should be used when the desired system needs to have a lot of interaction with the end users. * Typically, online systems, web interfaces have a very high amount of interaction with end users, are best suited for Prototype model. It might take a while for a system to be built that allows ease of use and needs minimal training for the end user. * Prototyping ensures that the end users constantly work with the system and provide a feedback which is incorporated in the prototype to result in a useable system. They are excellent for designing good human computer interface systems. In incremental model the whole requirement is divided into various builds. Multiple development cycles take place here, making the life cycle aâ€Å"multi-waterfall† cycle. Cycles are divided up into smaller, more easily managed modules. Each module passes through the requirements, design, mplementation and  testingphases. A working version of software is produced during the first module, so you have working software early on during the  software life cycle. Each subsequent release of the module adds function to the previous release. The process continues till the complete system is achieved. For example: In the diagram above when we work  incrementally  we are adding piece by piece but expect that each piece is fully finished. Thus keep on adding the pieces until it’s complete. Diagram of Incremental model: Advantages of Incremental model: * Generates working software quickly and early during the software life cycle. More flexible – less costly to change scope and requirements. * Easier to test and debug during a smaller iteration. * Customer can respond to each built. * Lowers initial delivery cost. * Easier to manage risk because risky pieces are identified and handled during it’d iteration. Disadvantages of Incremental model: * Needs good planning and design. * Needs a clear and complete definition of the whole system before it can be broken down and built incrementally. * Total cost is higher than  waterfall. When to use the Incremental model: * Requirements of the complete system are clearly defined and understood. Major requirements must be defined; however, some detail s can evolve with time. * There is a need to get a product to the market early. * A new technology is being used * Resources with needed skill set are not available * There are some high risk features and goals. Difference between spiral model and incremental model Incremental Development Incremental Development is a practice where the system functionalities are sliced into increments (small portions). In each increment, a vertical slice of functionality is delivered by going through all the activities of the software development process, from the requirements to the deployment. Incremental Development (adding) is often used together with Iterative Development (redo) in software development. This is referred to as Iterative and Incremental Development (IID). Spiral model The Spiral Model is another IID approach that has been formalized by Barry Boehm in the mid-1980s as an extension of the Waterfall to better support iterative development and puts a special emphasis on risk management (through iterative risk analysis). 4 Reasons to Use Fishbone Diagrams The fishbone diagram, or the cause and effect diagram, is a simple graphic display that shows all the possible causes of a problem in a business process. It is also called the Ishakawa diagram. Fishbone diagrams are useful due to how they portray information. There are 4 Main Reasons to use a Fishbone Diagram: 1. Display relationships   The fishbone diagram captures the associations and relationships among the potential causes and effects displayed in the diagram. These relationships can be easily understood. 2. Show all causes simultaneously   Any cause or causal chain featured on the fishbone diagram could be contributing to the problem. The fishbone diagram illustrates each and every possible cause in an easily comprehendible way; this makes it a great tool for presenting the problem to stakeholders. 3. Facilitate brainstorming   The fishbone diagram is a great way to stimulate and structure brainstorming about the causes of the problem because it captures all the causes. Seeing the fishbone diagram may stimulate your team to explore possible solutions to the problems. 4. Help maintain team focus   The fishbone framework can keep your team focused as you discuss what data needs to be gathered. It helps ensure that everyone is collecting information in the most efficient and useful way, and that nobody is wasting energy chasing nonexistent problems. Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change. It is a conceptual framework that promotes foreseen interactions throughout the development cycle. Rapid application development (RAD) is a software development methodology that uses minimal planning in favor of rapid prototyping. The planning of software developed using RAD is interleaved with writing the software itself. The lack of extensive pre-planning generally allows software to be written much faster, and makes it easier to change requirements. Code and fix Code and fix development is not so much a deliberate strategy as an artifact of naivete and schedule pressure on software developers. [5] Without much of a design in the way, programmers immediately begin producing code. At some point, testing begins (often late in the development cycle), and the inevitable bugs must then be fixed before the product can be shipped. See also: Continuous integration and Cowboy coding What Are the Benefits of Pareto Analysis? A Pareto analysis is an observation of causes of problems that occur in either an organization or daily life, which is then displayed in a histogram. A histogram is a chart that prioritizes the causes of problems from the greatest to the least severe. The Pareto analysis is based on the Pareto Principle, also known as the 80/20 rule, which states that 20 percent of effort yields 80 percent of results. For example, if an individual sells items on eBay, he should focus on 20 percent of the items that yield 80 percent of sales. According to Mindtools. com, a Pareto analysis enables individuals to make effective changes. Organizational Efficiency * A Pareto analysis requires that individuals list changes that are needed or organizational problems. Once the changes or problems are listed, they are ranked in order from the biggest to the least severe. The problems ranked highest in severity should become the main focus for problem resolution or improvement. Focusing on problems, causes and problem resolution contributes to organizational efficiency. Companies operate efficiently when employees identify the root causes of problems and spend time resolving the biggest problems to yield the greatest organizational benefit. Enhanced Problem-Solving Skills * You can improve your problem-solving skills when you conduct a Pareto analysis, because it enables you to organize work-related problems into cohesive facts. Once youve clearly outlined these facts, you can begin the planning necessary to solve the problems. Members of a group can conduct a Pareto analysis together. Arriving at a group consensus about the issues that require change fosters organizational learning and increases group cohesiveness. * Improved Decision Making * Individuals who conduct a Pareto analysis can measure and compare the impact of changes that take place in an organization. With a focus on resolving problems, the procedures and processes required to make the changes should be documented during a Pareto analysis. This documentation will enable better preparation and improvements in decision making for future changes. BENEFITS OF CONTROL CHARTS 1. Help you recognize and understand variability and how to control it 2. Identify â€Å"special causes† of variation and changes in performance 3. Keep you from fixing a process that is varying randomly within control limits; that is, no â€Å"special causes† are present. If you want to improve it, you have to objectively identify and eliminate the root causes of the process variation 4. Assist in the diagnosis of process problems 5. Determine if process improvement effects are having the desired affects 1st party audit First Party The first party audit is an audit carried out by a company on itself to etermine whether its systems and procedures are consistently improving products and services, and as a means to evaluate conformity with the procedures and the standard. Each second and third party audit should consider the first party audits carried out by the company in question. Ultimately, the only systems that should need to be examined are those of internal audits and reviews. In fact, the second or third parties themselves have to carry out internal or first party audits to ensure their own systems and procedures are meeting business objectives. SECOND PARTY (EXTERNAL) AUDIT Unlike the first party audit, a second party audit is an audit of another organization’s quality program not under the direct control or within the organizational structure of the auditing organization. Second party audits are usually performed by the customer upon its suppliers (or potential suppliers) to ascertain whether or not the supplier can meet existing or proposed contractual requirements. Obviously, the supplier’s quality system is a very important part of contractual requirements since it is directly (manufacturing, engineering, purchasing, quality control, etc. and indirectly (marketing, inside and outside sales, etc. ) responsible for the design, production, control and continued supportability of the product. Although second party audits are usually conducted by customers on their suppliers, it is sometimes beneficial for the customer to contract with an independent quality auditor. This action helps to promote an image of fairness and objectivity on the p art of the customer. THIRD PARTY AUDIT Compared to first and second party audits where auditors are not independent, the third party audit is objective. It is an assessment of an organization’s quality system conducted by an independent, outside auditor or team of auditors. When referring to a third party audit as it applies to an international quality standard such as ISO 9000, the term third party is synonymous with a quality system registrar whose primary responsibility is to assess an organization’s quality system for conformance to that standard and issue a certificate of conformance (upon completion of a successful assessment). Application of IT in supplying Point of sale  (POS) or  checkout  is the place where a retail transaction is completed. It is the point at which a customer makes a payment to a merchant in exchange for goods or services. At the point of sale the merchant would use any of a range of possible methods to calculate the amount owing, such as a manual system, weighing machines, scanners or an electronic cash register. The merchant will usually provide hardware and options for use by the customer to make payment, such as an EFTPOS terminal. The merchant will also normally issue a receipt for the transaction. Functions of IT in marketing Pricing Pricing plays an important role in determining market success and profitability. If you market products that have many competitors, you may face strong price competition. In that situation, you must aim to be the lowest-cost supplier so you can set low prices and still remain profitable. You can overcome low price competition by differentiating your product and offering customers benefits and value that competitors cannot match. Promotion Promotion makes customers and prospects aware of your products and your company. Using promotional techniques, such as advertising, direct marketing, telemarketing or public relations, you can communicate product benefits and build preference for your company’s products. Selling Marketing and selling are complementary functions. Marketing creates awareness and builds preference for a product, helping company sales representatives or retail sales staff sell more of a product. Marketing also supports sales by generating leads for the sales team to follow up. Market segmentation Market segmentation is a marketing strategy that involves dividing a broad target market into subsets of consumers who have common needs, and then designing and implementing strategies to target their needs and desires using media channels and other touch-points that best allow to reach them. Types of segmentation Clickstream behaviour A clickstream is the recording of the parts of the screen a computer user clicks on while web browsing or using another software application. As the user clicks anywhere in the webpage or application, the action is logged on a client or inside the web server, as well as possibly the web browser, router, proxy server or ad server. Clickstream analysis is useful for web activity analysis, software testing, market research, and for analyzing employee productivity. Target marketing A target market is a group of customers that the business has decided to aim its marketing efforts and ultimately its merchandise towards. A well-defined target market is the first element to a marketing strategy. The marketing mix variables of product, place (distribution), promotion and price are the four elements of a marketing mix strategy that determine the success of a product in the marketplace. Function of IT in supply chain Making sure the right products are in-store for shoppers as and when they want them is key to customer loyalty. It sounds simple enough, yet why do so many retailers still get it wrong. Demand planning Demand Planning is the art and science of planning customer demand to drive holistic execution of such demand by corporate supply chain and business management. Demand forecasting Demand forecasting is the activity of estimating the quantity of a product or service that consumers will purchase. Demand forecasting involves techniques including both informal methods, such as educated guesses, and quantitative methods, such as the use of historical sales data or current data from test markets. Demand forecasting may be used in making pricing decisions, in assessing future capacity requirements, or in making decisions on whether to enter a new market. Just in time inventory Just in time  (JIT) is a production strategy that strives to improve a business  return on investment  by reducing in-process  inventory  and associated  carrying costs. Continuous Replenishment Continuous Replenishment is a process by which a supplier is notified daily of actual sales or warehouse shipments and commits to replenishing these sales (by size, color, and so on) without stock outs and without receiving replenishment orders. The result is a lowering of associated costs and an improvement in inventory turnover. Supply chain sustainability Supply chain sustainability is a business issue affecting an organization’s supply chain or logistics network in terms of environmental, risk, and waste costs. Sustainability in the supply chain is increasingly seen among high-level executives as essential to delivering long-term profitability and has replaced monetary cost, value, and speed as the dominant topic of discussion among purchasing and supply professionals. Software testing Difference between defect, error, bug, failure and fault: â€Å"A mistake in coding is called error ,error found by tester is called defect,   defect accepted by development team then it is called bug ,build does not meet the requirements then it Is failure. † Error:  A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. This can be a misunderstanding of the internal state of the software, an oversight in terms of memory management, confusion about the proper way to calculate a value, etc. Failure:  The inability of a system or component to perform its required functions within specified performance requirements. See: bug, crash, exception, and fault. Bug: A fault in a program which causes the program to perform in an unintended or unanticipated manner. See: anomaly, defect, error, exception, and fault. Bug is terminology of Tester. Fault:  An incorrect step, process, or data definition in a computer program which causes the program to perform in an unintended or unanticipated manner. See: bug, defect, error, exception. Defect: Commonly refers to several troubles with the software products, with its external behaviour or with its internal features. Regression testing Regression testing is any type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes, such as enhancements, patches or configuration changes, have been made to them. Verification and Validation example is also given just below to this table. Verification|   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Validation| 1.

A quality assurance officer implements strategic plans, supervises quality assurance personnel and is responsible for budgets and allocating resources for a quality assurance division or branch. Levels of testing In  computer programming,  unit testing  is a method by which individual units of  source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine if they are fit for use. Intuitively, one can view a unit as the smallest testable part of an application. Integration testing (sometimes called Integration and Testing, abbreviated Iamp;T) is the phase in software testing in which individual software modules are combined and tested as a group. System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the systems compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic. In engineering and its various sub disciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests, physical tests, or performance tests. In systems engineering it may involve black-box testing performed on a system (for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. Software developers often distinguish acceptance testing by the system provider from acceptance testing by the customer (the user or client) prior to accepting transfer of ownership. In the case of software, acceptance testing performed by the customer is known as user acceptance testing (UAT), end-user testing, site (acceptance) testing, or field (acceptance) testing. A sample testing cycle Although variations exist between organizations, there is a typical cycle for testing. The sample below is common among organizations employing the Waterfall development model. Requirements analysis: Testing should begin in the requirements phase of the software development life cycle. During the design phase, testers work with developers in determining what aspects of a design are testable and with what parameters those tests work. Test planning: Test strategy, test plan, testbed creation. Since many activities will be carried out during testing, a plan is needed. Test development: Test procedures, test scenarios, test cases, test datasets, test scripts to use in testing software. Test execution: Testers execute the software based on the plans and test documents then report any errors found to the development team. Test reporting: Once testing is completed, testers generate metrics and make final reports on their test effort and whether or not the software tested is ready for release. Test result analysis: Or Defect Analysis, is done by the development team usually along with the client, in order to decide what defects should be assigned, fixed, rejected (i. e. found software working properly) or deferred to be dealt with later. Defect Retesting: Once a defect has been dealt with by the development team, it is retested by the testing team. AKA Resolution testing. Regression testing: It is common to have a small test program built of a subset of tests, for each integration of new, modified, or fixed software, in order to ensure that the latest delivery has not ruined anything, and that the software product as a whole is still working correctly. Test Closure: Once the test meets the exit criteria, the activities such as capturing the key outputs, lessons learned, results, logs, documents related to the project are archived and used as a reference for future projects. Types of Performance testing Stress testing (sometimes called torture testing) is a form of deliberately intense or thorough testing used to determine the stability of a given system or entity. Usability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. Volume testing refers to testing a software application with a certain amount of data. This amount can, in generic terms, be the database size or it could also be the size of an interface file that is the subject of volume testing. Maintenance testing is a test that is performed to either identify equipment problems, diagnose equipment problems or to confirm that repair measures have been effective. When it comes to quality management, IT organisations can take a leaf out of industry’s book. Thanks to the success of companies like Toyota and Motorola, methods such as Total Quality Management (TQM) and Six Sigma are gaining rapid popularity. And with good reason. Quality is a good generator of money, and lots of it. Unlike industry, IT has no physical chain. This makes it more difficult at first to be able to take concrete steps towards the implementation of quality management. But the parallels are easily drawn. Regard a satisfied end user as the equivalent of a faultless end product, a carefully conceived system of applications as the equivalent of a streamlined production line and so forth. And similar to industry, things can go wrong in any aspect. The faultless implementation of processes leads to significant savings (and not forgetting satisfied end users). What should you focus on to set up quality management for IT within your own organisation and subsequently make money? The service excellence strategy Organise a strategy of service excellence for the internal IT services, where the optimisation of service to end users receives top priority. After all, poor quality leads to high repair costs. Especially in IT. Resolving incidents costs money (direct costs). And the indirect costs, such as loss of productivity are, though often unobserved, several times these direct costs. Focus on management and service processes The focus within IT is often on the projects and the functionalities of the systems. But to ensure service excellence, the performance of management and service processes are equally important. If these processes are substandard, it could result in a lack of clarity, unnecessary waiting times and – in the worst case scenario – to malfunctions. A reassessment of processes is vital to prevent these discomforts and reduce relevant costs. Measure the effect of failure and errors The effect of failure and errors at the workplace is rarely measured. Organisations often have no idea how much these mistakes are costing them and what the consequences are for the service to their clients. The costs of incidents and malfunctions are easy to calculate by using a few simple rules of thumb. When you do this regularly, it will become clear for everyone where savings can be realised (read: how much money can be made). This will suddenly put the investments made towards achieving higher quality in an entirely new perspective. Use simple, service-oriented KPIs The moment you have insight into what causes the direct and indirect failure and error costs, it’s a small step to define a number of simple and service-oriented KPIs. These KPIs can form the guideline for measuring and improving service quality. Examples of such KPIs are: * The average number of incidents per employee; * The percentage of incidents resolved during the first contact with the helpdesk (the so-called ‘first-time right’ principle); * The percentage of incidents caused by incorrectly implemented changes. Implement a measurement methodology Improvements within a quality system happen on the basis of facts. The collection of facts takes place through measurements within the operational processes, on the basis of preselected metrics (e. . the number of complaints). The key performance indicators (KPIs) show whether a specific objective has been achieved, for example a desired decline in the number of complaints, expressed in percentages. Don’t overestimate the power of ITIL ITIL (IT Infrastructure Library) is a collection of best practices for the structuring of operational processes. Many companies have implemented IT IL in an effort to make their service more professional. ITIL lets you lay a good foundation to make the IT service more professional. But beware: it is no quality methodology. It might be good for defining IT processes, but offers no scope for actual improvement. So you will need a separate quality methodology in addition to ITIL. Most organisations require a drastic improvement in the quality of their IT services. Perhaps the realisation that this won’t be costing any money, but will instead generate it, offers the incentive needed to set to work earnestly on the issue. The end result means two birds with one stone: a service-oriented IT company that saves costs, and an IT company that truly supports the end users in carrying out their activities optimally. The Importance of Quality Improvement in Your Business Venture A career in the business industry requires you to be tough and flexible. Business is a difficult venture. You have to make your way through and outperform competitors. Businesses nowadays have also gone global. You have to compete with other business entities from the world over. Because of the tough competition in the business scenes, getting the attention and the trust of customers has become increasingly difficult. This is where quality improvement comes in. Quality plays a vital role in any business. Consumers want the best and want to pay the lowest possible price for products that are of the greatest quality. Moreover, quality is also one of the main components of being able to stay in the game despite the competition around you. Constant quality improvement is important in keeping you afloat. This has to do with eliminating or reducing the losses and waste in the production processes of any business. Quality improvement most often involves the analysis of the performance of your business, products, and services and finding ways to further improve them. There are certain techniques that can help you in achieving quality improvement. Knowing these steps can lead you to improved quality in your business. Benchmarking or comparing your company to the best or the top of the field will also be beneficial. You have to identify what makes an organization or company ‘the best’ and why the consumers want to purchase these products or services. Compare the quality and cost of their products with yours. Also include the processes that use to produce them. This can help you in looking for your own business factors that you have to improve upon for success. Setting up your own internal quality checks is important. You have to ensure that in ach step of making your product, you are meeting the standards of the industry and also providing your customers with the best products. This needs to be done with the least amount of waste and as few resources as possible. You need to be rigid about following the quality checks that your company has put forth. This will save you from having to deal with returned items and pr oducts. It also helps in guaranteeing the satisfaction of your customers. You need to assess your own production and your products. You need to know if these have passed the international standards on quality for the respective industry you do business in. Moreover, measure how your product is doing against others in the market. These are important in order to know what aspects you have to improve. You cannot afford to be forgiving when assessing. You need to be honest and blunt when gauging your own company. This will help you in finding needs for improvement. After assessing, you have to take the steps in making the necessary changes that will lead you to improvement. You may need to change your quality policy or do more research about your products and provide better features. You may also need to conduct training for your employees in order to update them with new methods in your processes. Quality improvement is not just a one-time process. It needs to be continued despite the success that a company or organization is appreciating. Competitors will always try their best to outwit you. And so, you have to continue on improving your products and services in order to offer more to your clients. This will not only lead you to more sales but also to a better reputation in the industry. Keep in mind that it is often more work to stay on top than to get to the top!

can money buy happiness Essay -- essays research papers

In today’s materialistic world, the phrase that ‘money can’t buy happiness’ is tending to be proved hence otherwise. Social research and surveys have shown results based on an individuals income, health and the political scenario which is dominant in his or her region. It is quite obvious that the gap between the privileged and the not so is growing into a great divide giving rise to different class and status, thus defining ones social circle. It should therefore be understood how an individuals economic status affects their personal happiness throughout all aspects of life. Many tend to refer to this age-old quote especially when they tend to belong to sector of people who can’t afford the modern day luxuries of life. What they do not realize is that money, might in fact do just that, buy happiness. On the other hand, those who have pockets as heavy as themselves think that money Is nothing but a burden and a complication in life, which is too net worked to figure out, let alone solve. Happiness as defined in the Oxford Dictionary is a feeling of luck, fortune and contentment. The trends of music have hip hop artists expressing their childhoods as miserable experiences because they grew up in the ghetto. However once they have acquired their wealth, things couldn’t have been going more smoothly. Could they have not made the best out of their childhood, knowing that they were loved and cared for? Weren't they truly happy then without all the material accessories? In my opin...

River Road Community

We re all going to have to learn how to walk again. After a nuclear holocaust devastates the country of the United States, the people of the River Road Community have to work through adversity and strive for the survival of every family. Households have to do without the things they would usually have taken for granted. They have to bond together to fight the trials of learning to walk. Frank s quote demonstrates his understanding of the task ahead of them as they start to learn to live again. They would have to begin by crawling before they can once more stand-up on both feet. Frank s quote is manifested throughout the story by the observed changes in the lifestyle of the community, the ways in which the diminishment of supplies are dealt with, and how the loss of community members forces others to take on new roles. After the nuclear holocaust, the lifestyle of the River Road community changed drastically. Before The Day, many residents of the community were wastrels. These rejects of society lived each day to eat, drink, and sleep. They lacked the drive to succeed in everyday life. After the bomb drop, everything changed. These blots on modern society crawled out of their shells in order to contribute something to a struggling society. They worked hard on construction and other things that would help the community. This strenuous work gave these once slobs a new outlook on life as well as the regular exercise they lacked. But, this sudden increase in work was not the only variable playing a role on them. After the bomb, anarchy broke out among community and surrounding towns. Highwaymen robbed the innocent, and people were taken advantage of. They had to start over. Randy gained leadership for the community. The next part was to gain control. He and other community members formulated a plan in which to regain control. Once it was obtained, laws were made that would govern the growing community. The government had started all over again. Another lifestyle serve was in the economy. The US currency no longer had value. With no gold to back up the paper money, it was worthless (except as toilet paper). Instead, the River Road community relied on the barter system. Trades were made for the items that were needed. If one person needed a spoon, they could trade some honey for it. Because of the nuclear holocaust, the lifestyle of the River Road community changed. Another way in which the community had to learn how to walk again, arose from the lack of supplies. Before The Day, many residents live on a diet of beer and nuts. After the bomb incident, many of the foods found in the pre-bombed world were no longer available. During chapter 666, the food supply runs terribly low. Helen and Lib create a new salad using leaves and other greenery found around the house. This new salad would never have been attempted had it not been for the lack of food due to the holocaust. The nutritional value of this green salad, compared to the beer and nuts, shows a positive improvement in nutritional content of their diet. Another loss came as a result of the loss of running water after the nuclear holocaust. Not long after the water was cut off the tub supplies and other rations of water, which had been stored up, were running out. The community had to limit its use of water and cut back on things that on a pre-bomb day would have seemed natural (like flushing the toilet or taking a bath). The community adapted the Artesian water to use as their source for water. This water was not as nice as the purified water they had previously had, but it was water none-the-less. The harnessing of this water required the help of many. LALALAALA. Also, when medical supplies ran low, things had to be improvised. With just the aid of a billiard table, steak knives, darning needles, hair curlers, and nylon line, Dan operated on Ben Franklin, removing his appendix. This is just one example where things had to be invented due to a lack of supplies. They also decided to use hypnotism as a form of anesthesia. Dan could speak a few sentences, and they would fall into malleable trance. He would then be able to operate without the patient feeling the procedure. Another example of the River Road community having to learn to walk again would be with food preservation. Without the use of refrigerators and other systems for keeping food fresh, there was a great need for salt. The salt could be used to preserve most meats. An animal could be slaughtered, and part eaten for a meal. The remaining portions of the animal could be salted and kept for a while. Towards the end of July, Randy noticed the salt supplies running dangerously low. He and many other members of the community had to set sail in search of a source for salt. They did return triumphantly with many bags of salt. These are all ways in which the community has adapted to a loss of supplies and had to work through the adversity and learn to walk again. The last way in which the River Road community had to learn to walk again was how the loss of community members forces the others to take on new jobs. When the towns were bombed, many skilled people were lost. Jobs needed to be filled and the residents of the River Road community rose to the challenge. Helen served as the barber for the group, cutting everyone s hair. Randy was the leader. He took control of the group and returned order to an anarchical society. Dan took over as the full time doctor, and Lib took over most of the cooking. Many Frank s quote, we re all going to have to learn how to walk again†¦, is manifested throughout the story by the observed changes in the lifestyle of the community, the ways in which the diminishment of supplies are dealt with, and how the loss of community members forces others to take on new roles. The great disaster affected everyone, and everyone pulled together to strive through the hard times. The community, crippled by the nuclear blast, regained strength and managed to walk again. The road there was filled with hardship and pain, but the path made them stronger. The River Road Community survived the nuclear holocaust, even though they had to learn how to walk all over again.

The Return: Nightfall Chapter 37

As she fell, it all rushed through her mind. The first time she had seen Stefan†¦she had been a different person then. Ice-cold outside, manic inside – or was it the other way around? Still numb from the death of her parents so long ago. Jaded by the world and by anything to do with boys†¦A princess in an icy tower†¦with a lust only for conquest, for power†¦until she'd seenhim . Believe. Then the world of the vampires†¦and Damon. And all the wicked wildness she'd found inside herself, all the passion. Stefan was her lynchpin, but Damon was the fiery breath beneath her wings. However far she went, Damon seemed to lure her on just a little farther. And she knew that one day it would be too far†¦for both of them. But for now, all she had to do was simple. Believe. And Meredith, and Bonnie, and Matt. She had changed relations with them, oh, most definitely. At first, not knowing what she had done to deserve friends like these three, she hadn't even bothered to treat them as they deserved. Yet they had all stuck by her. And now shedid know how to appreciate them – knew that if it came to that, she would die for them. Below, Bonnie's eyes had followed her dive. The audience on the widow's walk looked, too, but it was Bonnie's face that she stared into: Bonnie startled and terrified and disbelieving and about to scream and realizing at the same time that no screaming would save Elena from a headlong dive to her death. Bonnie, believe in me. I'll save you. I remember how to fly.

An Introduction to Rogerian (Person-Centered) Therapy

An Introduction to Rogerian (Person-Centered) Therapy Rogerian therapy, created by Carl Rogers, is a therapeutic technique in which the client  takes an active, autonomous role in therapy sessions. It is based on the idea that the client knows what is best, and that the therapist’s role is to  facilitate  an environment in which the client can bring about positive change. Rogerian therapy is sometimes called  nondirective  therapy because of the autonomy given to the client. The client, not the therapist, decides what is discussed. As Rogers  explained, â€Å"It is the client who knows what hurts, what directions to go, what problems are crucial, what experiences have been deeply buried.† Overview of Rogerian Therapy Carl Rogers believed that all people have the capability to bring about positive change in their lives. He developed person-centered (or Rogerian) therapy as a technique for giving clients greater autonomy in therapy sessions.  Rogers’ approach to psychotherapy is considered humanistic  because it focuses on individuals positive potential.   In Rogerian therapy, the therapist typically refrains from offering advice or making a formal diagnosis. Instead, the primary role of the therapist is to listen and restate  what the client says. Rogerian therapists try  to refrain from offering their own interpretation of events or from making explicit suggestions about dealing with a situation. For example, if a  client reported feeling stressed about the fact that a coworker was receiving credit for a project the client worked on, the Rogerian therapist  might say, â€Å"So, it sounds like you’re upset because your boss isn’t recognizing your contributions.† In this way, the Rogerian therapist attempts to give the client an environment to explore their own thoughts and feelings and decide for themselves how to bring about positive change. Key Components of Rogerian Therapy According to Rogers, successful psychotherapy  always has  three key components: Empathy. Rogerian therapists attempt to develop  an empathic understanding of their clients thoughts and feelings. When the therapist has an accurate understanding of the client’s thoughts and restates what the client says, the client is able to figure out the meaning of his or her own experiences.Congruence. Rogerian therapists strive for congruence; that is, being self-aware, genuine, and authentic in their interactions with clients.Unconditional positive regard. Rogerian therapists show compassion and acceptance towards the client. The therapist should strive to be nonjudgmental and accept the client non-contingently (in other words, their acceptance of the client doesn’t depend on what the client says or does). Rogers Later Work In 1963, Rogers began working  at the Western Behavioral Sciences Institute in La Jolla, California. Later, he co-founded the Center for Studies of the Person, an organization that is still active today. In California, Rogers worked on applying his ideas outside of traditional therapy settings. For example, he wrote about education in Freedom to Learn: A View of What Education Might Become, published in 1969. Rogers supported student-centered  learning:  an educational atmosphere in which students are able to pursue their interests, rather than passively absorbing a teachers lecture. Rogers also applied his ideas about empathy, congruence, and unconditional positive regard to political conflicts. He led â€Å"encounter groups† between groups in conflict, in the hope that his therapy techniques could  improve political relationships. He led encounter groups in South Africa during apartheid, and between Protestants and Catholics in Northern Ireland. Rogers’ work earned him praise from Jimmy Carter and a nomination for the  Nobel Peace Prize. Influence of Rogerian Therapy Today Carl Rogers died in 1987, but his work continues  to have an enormous influence on psychotherapists. Many therapists  incorporate elements of client-centered therapy in their practices today, particularly through the  eclectic approach, in which they may combine several types of therapy into one session. Importantly, the essential components of therapy that Rogers put forward (empathy, congruence, and unconditional positive regard) can be employed by any therapist, regardless of their specific approach to therapy. Today, therapists recognize that an effective relationship between client and therapist (called the therapeutic alliance or therapeutic rapport) is key for successful therapy. Rogerian Therapy Key Takeaways Carl Rogers developed a form of psychotherapy called client-centered therapy, or person-centered therapy.In client-centered therapy, the client leads the therapy session, and the therapist serves as a facilitator, often restating  back what the client has said.The therapist strives to have an empathic understanding of the client, have congruence (or authenticity) in the therapy session, and communicate unconditional positive regard for the client.Outside of psychology, Rogers  applied his ideas to the areas of education and international conflict.
