Implementing Software Development Project Management Best Practices Essay

Implementing Software Development Project Management Best Practices - Essay Example Somerville [1996 - Page 7] explains that successful software development, deployment, testing, deployment and maintenance are all built around four basic precepts : software specification, software development, software validation and software evolution. The obvious way of streamlining the software development process is to make these discrete stages flow into one another in a seamless end-to-end process. This requires, in practice, that the specific methods adopted for Rapid Application Development (RAD) (see (2) below) must be adopted, in order to avoid the hold-ups that always occur when discrete documents have to be updated to take account of changes in user requirements, for example. The greatest obstacle to software development, in practice, is the ‘big bang’ approach, where all the functionality is supposed to be introduced at once(!). The consensus of the available literature is that this may be charitably described as a recipe for disaster! The best, and therefore most streamlined approach is the incremental one, where software development is carried out in a series of relatively small steps. It is therefore vital that this principle is incorporated within the contract with the client (for a bespoke development) or the vendor’s marketing and sales departments (for a market-led project) 1. The Waterfall approach. This is where the requirements specification, design specification, test specification, implementation plan and maintenance plan are all produced in sequence as individual work products, and each is approved by the key stakeholders before the next is produced. 2. Evolutionary Development. Here, the specification, development and testing stages are interleaved, beginning with the very rapid development of a prototype system from a very basic specification. This is what us usually meant by Rapid Application Development (RAD). This prototype is then progressively defined with the aid of input from the intended users to produce

Queering a film (Hotel Transylvania 2012) Essay Example | Topics and Well Written Essays - 750 words

Queering a film (Hotel Transylvania 2012) - Essay Example Firstly and most obviously, Doty discusses the means by which the word â€Å"queer† is â€Å"used as an attempt to account for the existence and expression of a wide range of positions within the cutlrue that are ‘queer’ or non-anti, or contra-straight† (Doty 3). In this way, the reader rapidly understands that rather than merely promoting a certain point of view, the use and inclusion of such a phrase as an overarching world view denotes as much of what is not as what is. For this reason rather than merely denoting that the queer lifestyle exists and is an alternative to the pervasive expressions of straightness that exist, both societally and culturally, this specific use of the term helps to engage the viewer with an understand of what specifically queer is not and how it attempts to differentiate itself from the mainstream. As a function of accomplishing such an end there are multiple ways in which a filmmaker could seek to â€Å"queer† a movie. ... However, as Doty notes, a more equitable and fair representation of the queer world view and lifestyle goes beyond a simple representation of â€Å"homosexuality†. In this sense, the filmmaker is greeted with a difficult construct in which to work. On the one she may wish to incorporate these more nuanced interpretations of queerness; however, on the other hand, she may find herself somewhat stymied by that such nuanced representations of queerness would necessarily reduce to artistic expressions of highly sophisticated stereotypes. As a means to avoid such a simplistic approach, this author would recommend that rather than focussing on indvidiual aspects of â€Å"queerness† within the movie Hotel Transylvania, a clear contrast could be drawn between characters that represented both straight and queer worldviews/perspectives. Although imperfect, such a representation would be able to have a stronger effect than merely representing a gay couple or uniquely and perhaps ch eap representation of singluarly queer point of view on a given issue/topic. Moreover, as the word itself has developed a life of its own, Doty uses it in ways that are not traditionally associated with a homosexual lifestyle or worldview. As such, the therm has come to represent the many multifacted ways in which a rebellion against normality and standard definitions of the world exist. As the author states in the article, queerness was as much about a clear renunciation of societal mores/norms as it was about the ability to fall in love with and be romantically or sexually involved with a member of one’s own sex. In this way, one of the best ways to â€Å"queer† the movie would be

Human Papilloma Virus Essay Example | Topics and Well Written Essays - 2000 words

Human Papilloma Virus - Essay Example This paper critically reviews recent concepts in genital HPV linked to diseases, disease prevention, viral prevention, viral testing, and treatment. Health Canada goals and strategies for the control of human papillomavirus infection are represented (Rodriquez 2010). Periodic respiratory papillomatosis is chiefly a disease of children in whom several papillomas arise in the upper aerodigestive tract, involving the larynx and vocal cords. The papillomas collectively instigates thwarting papillomas might amount to respiratory suffering. Both high and low risk HPV-DNA series have been established in the papillomas. Although the viruses linked to the respiratory papillomatosis are not contacted through sexual intercourse, they are nonetheless most likely genital in origin, contacted during labor. Anogenital human papillomaviruses infection are chiefly transmitted through sexual intercourse, though in smaller cases there seems to be further, or optional, paths of transmission. Some crucia l proof asserts that rare cervical and penile infections may be contacted during labor through exposure to HPV extant in the maternal birth canal or external warts. A lot of concern has been placed on papillomatosis that is assumed to be contacted in this way. However, some peripheral anogenital warts may be contacted during labor as well (Brotzman & Julian 2006). 2. ... This paper critically analyses current HPV concepts and control issues including epidemiology, prevention, testing and burden of infection. Objectives of HPV control in Canada include establishing and evaluating the prevalence of HPV infection diminishing situations of HPV linked diseases, and promoting HPV targeted rudimentary science and clinical research. The advancement of vaccines is optimistic that the prevention of transmission and acquisition of the viral STD. There is a wide range of human papillomaviruses, which are over seventy types, and of these, over twenty infect mucosal tissue and can be transmitted through sexual intercourse. Human papillomaviruses are connected to the pathogenesis of cancer of the uterine cervix, which is the second most collective cause of cancer and cancer fatalities in women worldwide. Recent research shows that there is prevalent 80 percent of cases happening mostly in the developing world. Aggressive squamous cervical cancer is heralded by pren eoplastic lesions that can be established on Papanicolou (Pap) smear and consequently treated. The goal of screening for these precursor lesions has been linked to 90 percent reduction of cervical cases in some Western countries. Conceivably, over twenty types of this cancer linked types of HPV have been established; the most collective are types 16 and 18(Apple et al., 2005). These viruses are capable of integrating into the human genome, and by a range of mechanisms and mutations, including viral protein production and binding of human suppressor and retinoblastoma proteins, amount to unregulated mutations, and ultimately to malignant changes. Further, Oncogenic human papillomaviruses series have been established in the instantaneous

DDT and malaria Essay Example | Topics and Well Written Essays - 1750 words

DDT and malaria - Essay Example The disease is common in subtropical and tropical regions including a lot of Americas, Asia, and the Sub-Saharan Africa. Malaria is very common in these regions since they have reliable hot temperatures and large amounts of rainfall. Since mosquitos live in a warm environment with consistent temperatures, they breed continuously in the aforementioned areas. Significance of Malaria Malaria is one of the major contagious diseases in tropical environments and a huge public health disaster. It has been ranked the leading cause of death in the world where almost five million new cases are identified, with deaths of two point seven million annually according to Glaser and Knight (2007). Historically, malaria has infected humans since the creation of mankind. Malaria has not spared is victims despite of their status and position, the American President John Adams for example nearly succumbed to malaria while on a diplomatic mission in Amsterdam. It was until the nineteenth century that fact s about the real cause of malaria became known. So far despite this knowledge, malaria continues to grossly affect the populations of south East Asia, sub-Saharan, and Latin America its victims manly comprising pregnant women and young children (McConnell, 2006). Malaria causing mosquitoes are known to breed in swamy areas or areas that have stagnant waters where they lay their eggs. The Plasmodium parasite apart from infecting humans, also affects reptiles, birds, rodents, chimpanzees and monkeys. Plasmodium enters the bloodstream and damages the red blood cells as well as affecting the spleen, kidney, liver, and other vital body organs. Malaria has other names like falcipurum malaria, quartan malaria, black water fever, plasmodium, and tertian malaria. Thus malaria parasites are transmitted by female anopheles mosquitoes (Capinera, 2008). Information on the economic workload of malaria is needed to focus interventions equitably and efficiently, and to establish investment in contr ol and research of how to combat the disease. Treatment of malaria is costly its asociated expenses a burden to the victims. Many institutions use weak data to estimate indirect costs, which fail to account for seasonal variations, the difference between the marginal and average product of labour, and the means firms and households survive in response to the illness period. Impact of DDT There are several measures used in combating malaria including use of insecticides, mosquito nets and medication that fight the disease. One product that has been used for a long to in fighting malaria is DDT (Dichlorodiphenyltrichloroethane). DDT is a synthetic pesticide invented in 1874. DDT opens sodium ion paths in the neurons of insects enabling them to fire suddenly which results to eventual deaths spasms. However, in humans it affects the health through endocrine disruption or genotoxicity. Genotoxic substances are recognized to be potentially carcinogenic or mutagenic, particularly those cap able of causing genetic mutation and of contributing to the growth of swellings as noted by Miller and Spoolman (2008). DDT may be directly genotoxic, although it may also make enzymes generate other genotoxic intermediates. It is also an endocrine disruptor in that it act as an ant androgen. According to Roberts and Tren (2010), the remains of DDT on the walls of the houses can change the transmission mode of mosquitoes. The non contact repellant action of DDT remains can stop a malaria mosquito from entering the house. In

System Identification and Security Categorization Essay

System Identification and Security Categorization - Essay Example The principles of the CIA triad; integrity, availability and confidentiality are highly prioritized in the information system. Necessary control mechanism has been incorporated into the information security system in order to provide protection. These controls have been categorized to technical, management and operational controls. VA’s contain critical information and therefore effective organization, an accomplishment and supervision controls should be conducted with care. The main obligation of the e VAs is to accomplish the highest level of security while meeting the critical needs of an organization. The VA has been typically viewed by the majority as a mechanism for protecting information and information systems. This is not the case since its major concern is to protect the availability, confidentiality and integrity of the information and the information system. The control principles form the pillars of the CIA triad. Actions regarding risk management can be executed when planning, assessment of the significance of the risk and identification are carried out in a proper way. Though risk management will not absolutely eliminate risk, it possibly reduces the risk actualization, provides significant remedy and penitential risks in the future. The main goal of the VA is to protect information and information system through risk management program to achieve strategic and operational goals. The strategy adopted by the Information Security Management Act is based on risk approach. This is sated in the VA (2007), â€Å"the operating unit is responsible for conducting an accurate and thorough risk assessment to identify potential risk, vulnerabilities and threats to the confidentiality, integrity and availability of sensitive information held by VA.† The possibility of incurring a threat is potentially construed by the management  controls.  

Managing people at work Research Paper Example | Topics and Well Written Essays - 1000 words

Managing people at work - Research Paper Example Further, this move was based on the fact that teachers and principals are the people who interact directly with the students, and they are far much aware of the decisions that can work best for the students. This was supposed to add value to the quality of education that students received, without any restrains from the availability of resources. Notably, the federation was for the improved decision making that was school based as long as the approach did not jeopardize excellence and equity of schools, the curriculum that is statewide and staffing and resources guarantees. Further, the approach should not tamper with the entitlements and rights of teachers’ employment, as well as the primacy of the role of the principal who is the leader of education in schools (Mulheron 2012, p.3). This approach was to emphasize the primacy and significance of consultation, which should be genuine at all levels without a single compromise. Consultation approach received a warm welcome from t he NSW, and it had been incorporated in their recent education training programs. This approach had grand ambitions of eliminating the impositions of political agendas in schools; agendas that were predetermined by the politicians and policy makers. Apparently, it is essential that people should support the implementation of the NSW ideas to ensure that all children receive equal opportunities in schools, as well as receive high quality training. It imperative to note that, rejecting such a brilliant idea would send the society back to the dark days where some schools were residualized, and parents took their children when they were out of choices (NSW Teachers Federation 2011, p. 3). The core objective of this approach is to eliminate and avoid the emergence of a society that depends on wealth, parental influence and power to determine the opportunities of children, in schools and other education institutions. Rather, the approach compels the government to guarantee that all childr en receive equal chances and opportunities to receive the best quality education. Further, the NSW reform that was developed alongside the approach had crucial roles in the whole process, which included rebuilding and restoring the education system of the public to its original reputation. The ongoing debate found momentum when the minister for education conducted a process of consultation to devolve the making of decisions that affect schools to school communities, principals and teachers (Argyrous 2010, p. 39). These standards were supposed to apply in the process of provision of education services to students of the public schools in NSW. The federation of NSW teachers supports the implementation of policies that improve the principal’s capacity to deliver high quality of education to students (Chapman 1990, p. 48). However, this policy would remain viable as long as it did not diminish or undermine the excellence and equity for all schools and students. Further, the appro ach was supposed to guarantee staffing, resources and statewide curriculum to all schools and individuals (Smyth 1993, p. 53). Other considerations included the entitlements of teachers’ for employment and the educational leadership of the principal. On the contrary, those who oppose to the approach claim that increased autonomy of schools and the authority of principal will accentuate the disparity between schools, as well as have all the commonalities disregarded. Apparently, the supporters of this

Justice or moral uprightness of human soul according to Plato Essay

Justice or moral uprightness of human soul according to Plato - Essay Example Conversely, Plato (through Socrates) makes the contention that justice and morality are not socially constructed entities, but instead exist objectively. In this instance, humans should adhere to justice and morality regardless of the consequences. This essay considers these points in relation to the Republic and presents my own position on the debate. From the very opening of the Republic Plato sets about establishing the notion of justice and considering why it should be followed. One of the first aspects that are addressed in terms of justice concerns its very nature. In Book I Cephalus argues that justice constitutes following the laws and legal regulations that are established. Socrates refutes this claim arguing instead that while it would be legal to supply a madman with a weapon that you had taken from him, it would not be morally just as this could cause problems. A series of arguments regarding the nature of justice then occur, wherein an individual raises a socially constr ucted aspect of justice that is then refuted by Socrates in various ways. For instance, Thrasymachus argues that justice doesn’t exist, but is merely the demonstration of the stronger person or entity’s will.... Even if one were to indicate as much, it’s clear that the individuals in the society embrace their concept of justice. In these regards, it appears that in large part Socrates does not go far enough in considering the culturally conditioned aspects of justice, such as religion, or other socially constructed elements. In Book II of the Republic the consideration of justice is continued. At the beginning of this chapter justice is presented as a socially constructed aspect of society that must exist because of human wrongdoings. One notes that this understanding is contrary to Socrates previous presentation of justice as it reflects an understanding of justice that is only followed because it is advantageous for humans to do so. Within this mode of understanding, Glaucon proposes a story of a ring. He states, Suppose now that there were two such magic rings, and the just put on one of them and the unjust the other;,no man can be imagined to be of such an iron nature that he woul d stand fast in justice. No man would keep his hands off what was not his own when he could safely take what he liked out of the market, or go into houses and lie with any one at his pleasure, or kill or release from prison (Plato). In this scenario the ring would allow the individual to avoid punishment for being unjust. While Socrates later makes efforts to refute this theory, in large part one notes that a significant segment of society understands justice within this form of social contract. One also considers the earlier argument that justice is in large-part determined by the dominant party. In light of the current democratic structure of contemporary society and the means of establishing justice through
