SDLC methodology for designing a system Essay Example for Free

SDLC methodology for designing a system Essay The primary objective is to evaluate the SDLC methodology for designing a system. Prior to building a system, a set of methodology is essential in keeping the process kicking in right force so that it adheres to entire coverage and successful completion of tasks. It demands professional approach in planning, building and operating a system. SDLC methodology which encompasses several techniques in making the system travel smooth, processing the various steps required in putting together a system successfully. The spiral model which is a flavor of SDLC techniques corresponds in designing a system where business requirements are volatile in nature and communication with external entities is a priority. The spiral model would take into account all the primary steps in building a deliverable every time it completes a circle. Once it is finished with the planning and analysis phase the risk analysis task is taken in the picture. It is followed by engineering, construction and release, customer evaluation and finally customer communication. Once a cycle is covered, it results in a deliverable which is further processed upon customer communication and feedback. The SWOT analysis of the spiral model would contemplate the coverage of whether it can be taken up as a viable option in designing a system. The following is the analysis: Â · Strengths: The business environments are seldom volatile in nature where the requirements are ever changing and are adding every moment to expand their scope and stay competitive in the market. The spiral model would make sure that the proposed system is prone to changes. It provides enough mechanism to take into account the changes in the customers’ environment and act accordingly. Unlike other SDLC methods where the business requirements are completely taken as standstill when taking into account the building of the system. Unlike the waterfall model where the design stages are non-reversible in nature, once the stage is surpassed it cannot be revisited again. Â · Weaknesses: The weaknesses of the spiral model are that it is quite expensive in nature as every deployment is revisited with the spiral cycle once it receives a customer communication and feedback. It demands quite risk assessment expertise. The time taken to build the complete system is considerable high as for every new requirement is cycled all through from planning to implementation. The consumption of resources is substantially large as all the developmental stages are followed for creating a version of the system in every cycle. Â · Opportunities: The opportunities of using the spiral model are relatively high in comparison to the other models in use. The business external environment is fast changing to the requirements and enveloping newer challenges to analyze their market and take risks to prosper. In this situation having a flexible system development strategy would make it easy to design and build a system susceptible to frequent changes with changing business requirements. Taking into account the other methods available in the market, the spiral model would stand out in the crowd. Â · Threats: The other prototyping methods like RAD and Incremental methods of SDLC pose a threat to spiral method. The incremental approach is quite complex in operation but its flexibility is quite high in solving discrepancies. The RAD methodology is quite popular in SDLC but is not prone to taking the frequent changes into consideration which is a drawback.

The furture of early childhood education Essay -- essays research pape

The Future of Early Childhood Education   Ã‚  Ã‚  Ã‚  Ã‚  If you ask someone to list for you the most important jobs of our society, teachers always make the list sometimes beating out careers like doctor or lawyer. Ironically, for a career we value so much, teaching has never been a well paying profession. But times are about to change. Due to an increasing demand and a fixed supply, salaries for early education teachers are expected to increase within the next decade. The United States Board of Labor ranks this career as one of the highest paying of the next ten years, with an expected median tenure salary of over ninety thousand by the year 2012. Even taking into account inflation, working conditions, and different people’s preferred lifestyle, it is reasonable to say that a career in early childhood education can provide a very comfortable living.   Ã‚  Ã‚  Ã‚  Ã‚  The law of supply and demand helps us understand how price is set in our society. It states that if the supply of a good increases, or if the demand of a good decreases, then the price of the good drops. The opposite is also true, if the supply decreases and the demand increases, than a good becomes more expensive. The theory of supply and demand is very powerful, and can be applied to many different things. In this paper, it will be used to explain why teachers’ salaries are expected to increase a great deal. The number of teachers will be the supply, the need for teachers will be the demand, and salaries will be the price that will be affected. In 2002 there were over two million positions for early education teachers in the United States. Of the teachers in those jobs, â€Å"about 1.5 million were elementary school teachers, 424,000 were preschool teachers, and 168,000 were kindergarten teachers†(Outlook). The majority of these teachers worked for the local government educational services, with about ten percent working for private schools. While the majority of preschool teachers are employed by child daycare services. Geographically, teaching positions vary with the population. Highly populated areas have more employment opportunities. Every year, a greater number of students enroll into the United States school system. More students increase the need for more schools and qualified teachers. In addition to the population growth, a number of initiatives have been impl... ...their families.   Ã‚  Ã‚  Ã‚  Ã‚  State employed teachers will not have to worry about retirement, because they are guaranteed a pension salary once they retire. Teachers will not have to stress or fear for the future like some other members of the workforce who were relying on social security.   Ã‚  Ã‚  Ã‚  Ã‚  Early childhood teachers also have the satisfaction of having a career in one of the most respected professions in our society. They will have to fulfillment of knowing that what they do makes a difference. Works Cited Case, Karl E. †Principles of Macroeconomics† Sixth Edition.

Chronic Illness Research Paper

Wiskott-Aldrich syndrome is an X-linked recessive immunodeficiency disorder usually inherited by males from their mother. This syndrome involves both T- and B-lymphocytes characterized in one third of patients by the triad of recurrent bacterial sinopulmonary infections, eczema (atopiclike dermatitis), and a bleeding diathesis caused by thrombocytopenia and platelet dysfunction.The characteristic triad of bleeding, eczema, and recurrent infections in Wiskott-Aldrich syndrome generally become evident during the first year of life, with petechiae and ecchymoses of the skin and oral mucosa and bloody diarrhea being the first clinical signs. Bone marrow transplant improves prognosis of Wiskott-Aldrich syndrome. Investigators reported that before hematopoietic stem cell transplantation, cutaneous manifestations occurred frequently, with the most common lesion being eczema similar to atopic dermatitis (71%), followed by petechiae and/or ecchymosis (58%) and cutaneous infections (17%).The c lassic triad of symptoms was seen in 46% of the boys, who were later treated with hematopoietic stem cell transplantation. The chronic underlying medical needs, the unpredictable nature of the disease, with its share of life threatening emergencies, all contribute to a stressful life for the family. These families need support from physicians, family, friends, teachers, clergy, neighbors and sometimes professional counselors to help them cope with the disease.Families living with Wiskott-Aldrich Syndrome are challenged by many stressors and often struggle with the imbalance it causes. Some of the stressors of WAS include variability of the disease's presentation, sudden and unexpected onset of the symptoms (infection, bleeds, malignancies and autoimmunity), the lack of consensus in the medical community on how best to treat WAS, and the incurable nature of the syndrome without bone marrow transplantation that in itself carries significant risk of serious side effects including death .They also struggle with the potentiality that their child's symptoms may increase or worsen with age, and, because of the rarity of the syndrome, families are often dealing with a disease that is not well understood and specialists that are often hard to find. These types of acute and prolonged stressors naturally challenge the safety and predictability within the family system and also the emotional stability of all members within including the child affected with WAS as he ages. Although each family is unique and each family member is different in the ways in which he or she esponds to the stress and trauma associated with WAS, many experience moderate to profound grief, anxiety and or depression. Some experience hyper-vigilance, avoidance of situations or places reminiscent of traumatic events associated with WAS, have nightmares or recurring intrusive traumatic thoughts or images associated with the trauma and or isolation. While others may experience panic attacks, sleep distu rbances, eating disorders, ADHD-like symptoms, under performance at work or school and or symptoms of oppositional defiance.Management of infection includes antibiotics and possibly intravenous immunoglobulin G (IVIG). The decision to use prophylactic antibiotics and/or IVIG is made case-by-case, based on incidence and severity of infection in the individual patient. Postsplenectomy, prophylactic antibiotics are mandatory, although the patients who undergo splenectomy remain at considerable risk for overwhelming sepsis despite of prophylaxis. The nurse must teach that immunization is mandatory.Varicella-zoster immune globulin is administered within 48 hours if possible, although it may be effective until 96 hours post exposure. To manage acute bleeding the nurse’s role is to administer platelet transfusions and packed erythrocytes. The nurse must also insure that she and the healthcare team are minimizing exposure to allogeneic cells in the patient for whom stem cell reconsti tution is planned is important because such exposure increases graft rejection rates.The nurse must teach the parents how to manage symptoms of eczema at home along with an oral antiviral that the child will be receiving. Parents are taught to treat eczema with conventional topical moisturizing creams and topical steroids. Nurses also advise that milk and other potential food allergens may be eliminated from the diet on a trial basis to observe for improvement. Clinical services provided for the family and child coping with Wiskott Aldrich Syndrome include, groups such as the Wiskott Adlrich Foundation.This foundation is awarded grants to help unraveling the mysteries of WAS, explore avenues for improved cures and find ways to improve the quality of life for those who are impacted by WAS. Resources provided in the U. S. include financial assistance, fundraising assistance, housing-travel and medication, wish granting organizations, and educational scholarships. These assistive progr ams provide the family with detailed information about their disease, and financial supports to cope with the stresses that come with treating and the management of WAS.When dealing with WAS the family is taught that nothing is more important to the health of a child with WAS than warding off potential infections. Basic precautions including: keep the child away from crowds, dirty environments and sick people; use protective face masks at the recommendation of the child’s doctor; following a strict hand washing regimen for the child, family, and visitors. These actions are taken because the child’s body does not have healthy B cells that produce antibodies against infection, they may also need regular infusions of the antibody immunoglobin.Works Cited Boztug, K.

How Technology Changed the world Essay

Over the last five years, technology has been rapidly changing and expanding in every field imaginable. Smart phones are now capable of acting as standalone computer devices that can take pictures, search the Internet, send emails and text messages and yes, they even make phone calls. While it might seem that the technology of today has reached its limits, it is still actually spreading its proverbial wings. Only twenty or so years ago, personal computers were becoming small enough and affordable enough for families to buy them for home use. Since then, the world of technology has shown no signs of slowing down and practically every device available today is somehow tied to computer technology. From the first day that technology was introduced to war, it has helped shape the latter. Flint-made daggers and spears, and leather or wickerwork shields, did quite as much to shape the tactics adopted by ancient societies as horses did during the middle ages and as tanks, aircraft, and vario us combat ships do today. All transportation depends on technology, whether it’s the wheel, the jet engine, or the computer chip. Transportation is not just technology it’s a system of technology, people, energy, money, and more—but advances in technology play a key role in shaping transportation systems, which in turn help to shape our lives, landscapes, and culture. Because transportation is so important to commerce, because literally and figuratively so much is riding on it, it has been the focus of an enormous amount of inventive activity. Corporations have invested billions of dollars in improved technology. Individuals have sought their fortunes in breakthroughs big and small. Technology has changed society tremendously. Things like iPods, Netbooks, BlackBerrys, Blue Tooth, and flash drives have definitely not been around for a long time. Our society today has many advantages thanks to technology. Law enforcement officers have a great advantage with things like  GPS and tracking devices and cell phone records. The general public also faces a lot of distraction because of some technology though. Car accidents used to be caused mostly by people falling asleep or drunk driving. Now the big concern is that people are playing with their gadgets, messing with music players, playing DVDs in the background for kids, and talking on their cell phones. That is a lot of potential distractions! Society is becoming a union of ‘we want it now’ people thanks to most technology offering super fast services. There isn’t enough stopping to smell the roses anymore. For the most part, however, technology does us more good than harm: It’s reconnected us with old college roommates, helped us learn a foreign language, and encouraged us to exercise. Follow us as we look back at how technology has changed our lives—for the better and for the worse—in terms of communication, computing, dining, entertainment, and travel. http://ezinearticles.com/?How-Technology-Affects-Us&id=7429569 http://www.ehow.com/info_7844707_impact-technology-warfare.html

Essay Sample on Scholarships in the Community Services

Essay Sample on Scholarships in the Community Services To become involved in community service, an individual should first acquire the kind of education that will provide the skills needed in carrying out a community service. Given that community service is a wide field, it is important that when seeking an education, one should specialize in the field of community service in which one plans to work. The field of community service that I am interested in is helping individuals to develop parenting skills. Parenting can be very rewarding; it can also be very frustrating if one is not prepared to have children. There is very little training that is offered to expectant mothers and fathers, and very few people seek training before deciding to become parents. This has resulted in a situation where parenting skills are taken for granted. By providing parenting education through community service, perhaps I will be able to offer parents and those who intend to become parents, the kind of knowledge that will enable them to carry out their parental roles in a positive, nurturing manner. One of the areas of parenting that I am especially interested in is infant care. Infant care begins with good prenatal care. Expectant mothers and those planning to become pregnant could attend classes on good eating habits, appropriate exercise, and the importance of doctor care and prenatal vitamins. I could develop a number of pamphlets on these topics, start a blog for those who have access to the Internet, and establish a phone helpline. I could also develop a website with a list of online resources, including addresses and telephone numbers. This information would be included in the pamphlets, as well. Furthermore, I could invite obstetricians to discuss with groups of expectant mothers what to expect during the trimesters of their pregnancies, as well as during birth. Furthermore, I could develop parenting classes for parents of children in certain age groups, like babies, toddlers, preschoolers, etc. The topics related to parenting are endless. Throughout my career in serving parents, I would continuously take courses, read studies, attend workshops, and develop both materials and instructional workshops for mothers, dads, as well as different kinds of family structures. Subjects would be wide-range, including how to establish at-home routines for doing homework, eating a healthy dinner, bath-time, and bedtime. Topics for older children could also be developed, such as dealing with sibling rivalry, determining when a child is old enough to complete household chores and what kinds of chores are appropriate at what age. Topics could also include the blending of two families into one when a parent marries someone. Overall, I am excited at the opportunity of serving a community by helping it be stronger through strengthening the family unit. Tips for writing: Since this is a scholarship essay for community service, the reader expects the writer to provide reasons why the reader should grant the writer a scholarship in community service. These reasons should include the field of community service that one is interested in and also an explanation of what one plans to do with the knowledge acquired from the institution once the applicant is granted the scholarship and then graduates from the college. In this case, the writers’ choice with regards to community service is providing support to expectant and existing parents in having healthy babies and raising well-adjusted children.

Rhetorical analysis for a TV commercial Essay Example | Topics and Well Written Essays - 1000 words - 1

Rhetorical analysis for a TV commercial - Essay Example But for somebody who did not live in America and did not experience the fear of terror when the country was attacked, one can only empathize and be sensitive to what they went through. This is important to mention in this rhetorical analysis because this is the context of which the information advertisement was made. Ethos is the use of credibility and/or authority in making the message effective of an advertisement, speech or anything that a person would like to convey. Ethos removes the barrier of resistance and doubt among the audience of a message because they believe the person or institution who is giving the message. In the advertisement or information campaign, it is the US government who is giving the information through the Department of Homeland Security. The US government being credible among its citizen, it follows then that the commercial of Department of Homeland Security will be credible among the audience. The use of authority by mentioning the institution who provide the advertisement is also added by the way the clip was made. It is consistent with how law enforcements warns the people or guide them on what to do during a situation. It only asked to report anything suspicious because not all suspicious things are and thus made the clip very credible. Logos is the use of reason or logic to support the claim. This can be done either by making a good point or mentioning studies or statistics to support a message that would make it credible. In the clip, the logos or logic of the advertisement has to be read between the lines and one has to understand the bigger context of the video was made. It was made with the understanding that if one will not report what they see, then the government will not have an idea of the threats that are happening and that, terrorism might again attack them. It was not explained verbally why people has to report suspicious behavior but the people who will see the clip will
