Formal and Informal Software Development Techniques free essay sample

Compares and contrasts the use of formal methods and informal methods within the software process. This paper investigates the role of formal methods (such as Z, Object-Z, VDM, B) within the software process and compares these to less formal methods such as natural language specifications and semi-formal methods like UML/Fusion. The complexities of formal methods are weighed against the software quality benefits often achieved through their use. Overall cost-effectiveness of both methods are discussed, as well as situations where formal methods may not be required (non-critical applications, rapid prototyping). While it is clear that both formal and informal methods have their own inherent benefits and shortfalls, it seems as though formal methods are the best option if software quality and overall cost-effectiveness are to be maximized. With increased tool support and method standardization, barring personal preference, there are few reasons why a formal approach should not be implemented. Increased acceptance of formal methods would most likely lead to higher quality software due to the more complete and precise specification that mathematical notations allow.

Handling International Terrorism essays

Handling International Terrorism essays The September 11th attacks marked a clear escalation in quality of international terrorism. They have comprehensively changed the way in which we think about terrorism and react to it. The terrorist attacks proved that geographical separation from the area of operations no longer safeguards homeland security. It further reinforces the widely held assumption that international terrorism is the main threat to European security. Nowadays words and concepts such as culture of fear, civilization clash, rogue states, pre-emptive war, weapons of mass distraction, willing coalition and asymmetric war have become very common, even in informal speeches and in daily discussions with friends and family. International terrorism is a very wide problem that encapsulate a different and varied aspects. The type of terrorism causing most contemporary international concern is a very complex phenomenon. Its manifestations, such as a systematic use of violence and intimidation, are as many and various as its motivations. Its peculiarity is in its capacity to reinvent itself. It does not have flags or border. It would be a big mistake if we assumed that any group with an extreme ideology must be directed by al-Qaeda, or by one of its regional offshoots. Terrorists have surprised and shocked us - in terms of who has been targeted, when, how and on what scale. Terrorists simply do not always do what others expect them to do. There is a significant capacity for terrorists to do harm, and on a very large scale, and it should never be underestimated. Commuter transport systems remain immensely vulnerable in every major city in the world (i.e. the nerve agent Sarin, used in Tokyo underground attack); highly destructive conventional bombs can be made using the cheapest and most freely available mat ...

The similarities and differences about buddhism between China and Research Paper

The similarities and differences about buddhism between China and Japan - Research Paper Example idual choice for a particular religion is not one unique aspect as there are several influences that make one follow the belief of their ancestors by default. It is only when one is mature enough to think and ponder upon the teachings that he either becomes more devout in his beliefs or seeks new religions to satisfy his thirst for a solid system of principles that he deems supportive and moral. Buddhism is one of the five most followed religions of the world. The concept revolves around the attainment of a state of satisfaction or nirvana, through spiritual development, meditation and acting upon principles of morality and wisdom. The word Buddhism is composed of the word called ‘budhi’ that means enlightenment or awakening. This signifies the origin of Buddhism as the awakening of Siddhartha Gotama’s mind at the age of 35, some 2500 years back. This man is now known as Buddha and his idols are paid respects by the followers of Buddhism worldwide. The concept of a creator or a God is not included as the teachings of this religion, thus is does not revolve around strengthening the bond between the creator and the humans. On the contrary, it believes that change is inevitable and in order for a person to attain a state of spiritual satisfaction he has to act morally and follow the teachings that are designed to help him live through his lifelonguncertaint ies without being wavered. The concept of Buddhism basically starts off with the journey of Buddha and his path of enlightenment. Buddha was born in a royal family in today’s Nepal 2500 years ago. Not having seen any suffering or discomfort in his life, he lived peacefully within his family’s royal enclosure. However, once he stepped out into the real word he saw scenes that were unknown to him, that of poverty, suffering and the harsh realities of life. This incident made him set out to find a balanced way of life that was fair and neither of the two extremes of poverty and luxury. He was resting during

Hiroux's Basic Principles of Morality Essay Example | Topics and Well Written Essays - 1000 words

Hiroux's Basic Principles of Morality - Essay Example When we evaluate the United States through the lens of Thiroux's basic principles, we find a country that is striving for moral idealism and compromising to satisfy reality. When considering the United States, it needs to be defined as a culture and society of people, religion, and laws. It is not the canyons, mountains, and buildings. The morality of the United States extends to the people, their laws, and the philosophical underpinnings of the constitution. Giving a moral standing to the inanimate objects within our borders would go beyond the traditional boundaries of the moral universe (MacNiven, 1993, p.204). When we apply Thiroux's five principles, we examine the people, the law, and the principles as they are applied to the people in our own country and around the world. When evaluating a situation or a people for its ethical nature it is critical that we have the truth. Honesty, one of the five principals, is the foundation that morality is built upon. Our major religions embody the principle in the ninth commandment of 'thou shalt not bear false witness'. It is reflected in our expectation of truth from our leaders and courtroom testimony. However, the US is inundated with false and misleading advertising, and our country goes to war based on a deception. In the US, honesty is generally valued only so long as it is in our own self-interest. In the long term, the self-interest of corporations and politicians can become the illusion of honesty (Mansbridge, 1990, p.151). While the US embraces honesty as a concept, the principal is often overrun by self-interest. A fundamental moral principle is the sanctity of life and the belief that we should celebrate life and accept death (Thiroux, 2007). The United State's Declaration of Independence expresses the similar belief when it says that one of our inalienable rights is our right to life. This moral principle is reflected in our laws that prevent assault or murder, as well as the fundamental respect for life that is practiced by our mainstream religions. Still, abortion laws, lack of child health care, and militaristic adventures call into question whether this is a guiding principle of the US or merely words to strive for. Here we see our principles overlapping and contradicting one another. Freedom of choice and a right to privacy impede the idealism of the value of life in regards to health care and abortion (Thiroux, 2007). It is also argued that military action serves to save a greater number of lives than it takes. No system of laws or government has a greater respect for individual freedom than the democracy of the United States. Once again, the principles are valid only within a well defined context. If questioned, many Americans would express the feeling of exploitation and slavery to the economic system. Personal freedom is only attainable if the freedom is in itself moral. The United States has made incremental progress towards individual freedom, though we do not have the absolute freedom to do as we please. Our morality may be at odds with someone else's value system. Henry David Thoreau (1892) said, "The progress from an absolute to a limited monarchy, from a limited monarchy to a democracy, is a progress toward a true respect for the individual" (p.151). While the United States has the ideal of a universal morality, our diversity challenges our individual freedo

Importance of Inter-professional Working in Nursing Practice

Importance of Inter-professional Working in Nursing Practice Inter-professional working is constantly promoted to professionals within the health and social care sector. Various terms such as interdisciplinary, multidisciplinary and interagency collaboration working have been used to promote professionals to work together with the patient, carers, relations, services and other professionals (SCIE, 2009). This Paper will explore the importance of inter-professional working in nursing practice, due to nurses supporting and treating a variety of patients. This paper will discuss the general importance of inter-professionalism as part of good nursing practice, it will use examples of adult stroke patients and children who have cerebral palsy. These two conditions have been chosen because they allow the paper to explore two different age groups and the needs of patients who tend to have complex social and healthcare needs. There is also a wealth of literature available on these conditions which helps highlight the need for nurses to work effectivel y with other health and social care professionals, service providers and carers. Patients initially tend to see nurses either alone on arrival at accident and emergency departments, or in conjunction with a medical practitioner. Therefore, the duration of time that a nurse spends with a patient tends to be longer than most other health/medical professionals (Godfrey, 2012). Ward nurses who work on hospital wards, provide care and support to admitted patients throughout their whole stay. This length of time spent with the patients allow them to be familiar with the patient, hence allowing them to recognise changes in a patients health and also to identify any new needs. Often, patients need to see more than one health/medical professional in their stay at the hospital, due to their health needs. Despite these professionals possessing specialist skills to support or treat specific health concerns that the patient may have, often the health recommendations that are given to the patient need to be performed routinely even when the patient is not in the presence of th is specialist. Therefore, allied health professionals tend to advise, seek the support of, or hand specific recommendations over to nurses. This is often seen between nurses and physiotherapists in mobility recommendations, this is because nurses often have to mobilise a patient out of hours as recommended by the physiotherapist (Godfrey, 2012). This avoids the patient having to wait for a physiotherapist on weekends, or to become frustrated due to being in one position for long periods of time and it also supports the overall hospital service aim of better patient outcomes. Similarly patients with complex physical issues, minimal mobility or neurological complications, such as stroke patients, need to be regularly moved to avoid pressure ulcers developing. In addition to this, regaining mobility gradually is often part of a patients stroke rehabilitation programme. Clear guidelines and training are given, as recommended by NICE, to nurses to perform safe moving and handling techniques on patients. These guidelines advise 2-3 trained professionals to move a patient who is bed bound, depending on the patients movement ability and weight (Jacob et al, 2007). If this is a stroke patient this needs to be done on recommendation of a physiotherapist (RCP, 2012). Therefore, it is important for nurses to communicate effectively with other health and social care professionals when moving and handling a patient who may have complex needs, as nurses may need specialist recommendations by the physiotherapist, or the patient may have medical equipment attached to the m which needs to be handled carefully or removed temporarily. Safe moving and handling techniques as part of a team effort not only promotes good health and social care practice, it also decreases the risk of injury to a nurse. This is particularly important as moving and handling injuries have been the most common causes of staff absence for a period of 3 days and longer between the years of 2007 and 2013 (Anderson, 2014). A key feature of hospital care is information sharing through ward rounds done by doctors and other health professionals. The aim of this is to provide patient care which can be delivered in a timely manner, but it also allows the multidisciplinary team involved with the patient to plan their future care and treatments. Nurses input via reporting to colleagues their judgement and observations on the patients current health state is not only vital for better care planning in the future, but it is also important because nurses can often voice the preferences that patients have expressed to them, hence promoting the principle of patient centred care (RCP and RCN, 2012). Furthermore, due to the direct care ward nurses give on their shift throughout the day to allocated patients, they often recognise the general deterioration of a patients health and wellbeing before other health professionals and doctors. Therefore, it is extremely important for the safety and well-being of patients for nurses to liaise with doctors regularly to manage the change of symptoms as soon as possible. Even though patient care planning is revisited and documented regularly by health and medical professionals when changes are needed for the patient, formal multidisciplinary meetings allow improved outcomes for the patient, an example of an improved outcome is when Stroke Early Discharge Support Teams can discharge patients earlier, allowing them to more likely be independent sooner in their daily tasks (Clarke, 2013). The multi-disciplinary team who has contributed to this evidence has consisted of specialist medical practitioners, various speciality therapists, dietitian, a care manager, nurses and sometimes a social worker. Nurses, due to possessing past history medical notes and the knowledge of relations who visit the patient, can usually provide the occupational therapist and the allocated social worker with information on key relations of the patient that maybe useful to contact prior to discharge. Also, nurses through conversation can gather information on the patients living situation at home. This is paramount in discharge planning for stroke patients as sometimes they are unable to communicate fully and clearly their living environment at home, as stroke can impact an individuals ability to communicate verbally and physically. Also, if patients have few or no relations living with them, they may need home care via nursing staff or telecare equipment which can support risks of injury or allow individuals to alert emergency care services via sensory equipment when they have a fall or another stroke which results them to fall. Even though occupational therapists will do assessments of the environment which the patient resides in (EKUHFT, 2015), nurses can often give the therapist insight on any issue the patient has had in their stay at the hospital, an example of this may be that the patient has difficulty lowering themselves to sit on the toilet, the occupational therapist would usually request for a grab/hand rail to be fitted in the patients home to support them to do this action. Patient care planning via inter-professional working is also fundamental to children who have been born with Cerebral Palsy. Nurses with specialist roles such as Health visitors, provide a community based service to cerebral palsy patients and their families. This differs to the role of nurses on the ward as Health visitors review the health of the patient in reference to their living environment and public health needs, hence allowing them to identify the wider health needs of the family too (Alexander, 2014).. Due to cerebral palsy being a non-curable condition the child and the family/carers of the child will regularly receive treatments and support from an extended network of health and social care professionals and also educational specialists and support staff (NHS, 2014). Therefore, health visitors need to be able to create successful inter-professional relations with professionals who are external to the health and social care industry such as educational psychologists, by un derstanding the role and service that the professional is providing to the patient. It is also vital to understand roles due to the referral systems we have in the United Kingdom, both within hospital and community care. Furthermore, policies can differ between the local authority, the NHS and private healthcare providers and the child and his/her family may have chosen to have a specific care package which the health visitor may not be aware of (Know your rights, 2015; NHS, 2013). Also, Health visitors often need to liaise with professionals who are not employed by the NHS or another private healthcare provider but by a local authority instead. This can mean the caseload is allocated differently, waiting times may differ and methods of referral may differ too. Therefore, to ensure that the patients transition is efficient and positive from immediate hospital care to accessing community based services, nurses need to be aware of the basic structure and logistics of other services. This awareness needs to be raised more specifically in the working environment for younger student nurses or graduate nurses who may not know the difference between certain professional roles, as despite accredited nursing programmes having modules or lessons in multidisciplinary practice covering the importance of knowing the roles of other health and social care professionals, sometimes there is confusion between specialists who support patients or service users with the same condition(s). A classic misunderstanding is a student nurse struggling to understand the difference between a mental health social worker and a mental health nurse, who can both work for community based teams and may be employed by the local authority (The Masked AMHP, 2012). The administration of medication is another role that nurses carry out in health and social care settings. The administration or preparation of medication is usually done by using the skills learnt from their training, instructions from the pharmacist or manufacturer guidelines. However, human error in the administration or preparation or omission of the medication can put the patient at risk of poor health or even death (NICE, 2014). Hospital pharmacists and dispensing staff function in a fast paced environment, hence processing prescriptions for medications that are needed for patients on the ward who vary in conditions. Some medications are needed urgently and human error can occur on the behalf of pharmacist or dispensing staff. Despite pharmacy staff recording clinical errors as part of their good clinical practise, nurses also need to be aware of these errors for the patients safety and awareness also needs to be raised to other nursing colleagues of the issue because the patie nts health may need to be checked regularly. . Furthermore, as doctors complete prescriptions for the request of medications, nursing staff only follow the patients drug chart in administrating the medication, hence it is vital for the nurse to understand what the doctor is prescribing the medication for (UHS, 2015). This is important to know as the nurse may observe patient changes after the patient has had the medication, which need to be recorded. To avoid error and to justify their clinical actions in medical administration of drugs, nurses need to be able to follow the advice and instructions of both the doctor and pharmacist, therefore effective and open communication allows questions to be asked and concerns to be raised, hence creating a strong working relationship. This protects not only the patient but it also improves working relationships between medical and nursing staff. Also, nursing staff and doctors caring and treating patients with cerebral palsy have to work using a comprehensive rehabilitation approach, which includes working alongside physiatrists who manage anti-spasticity medication and review medical complications associated with cerebral palsy. Hence, nursing staff need to have a broad understanding of the specialisms of the medical practitioners that they are liaising with, as often nursing staff liaise with several different specialists. To conclude, inter-professional working is clearly important for all health and social care staff, however it is extremely important for nursing staff because their varied role requires them to liaise with different professionals, settings and patients. Also, as nurses can now undertake CPD to specialise in areas such as such as stroke, diabetes, palliative care and disability, their role has changed from providing traditional nursing through practical care to now being able to provide specialist advice to the patient and relations on the management of the condition. (Niece McEwen, 2015). For nurses to be successful in their specialist roles they need to create positive working relationships with other health/medical staff, non-clinical professionals, carers/families and most importantly the patient. Furthermore, due to the demand of nurses in non-clinical settings such as homes and schools, for nurses to practice effectively they need to be able to understand the roles of professio nals practicing in community settings as often these professionals can provide the nurse with how the patient functions in their daily life. Due to ward nurses providing care throughout their shift, usually to the same patients, the greater length of time with the patient allows them to have a better insight to the patient and their health whilst in care of that ward. This allows them to feed back to fellow nurses and other health/medical professionals any changes that need to be made to the patients care plans. It seems not only is patient care improved by inter-professional working but also the skills and knowledge of nursing staff is also developed by learning from other professionals, it is likely that in the future, guidelines will further advise nurses to work more inter-professionally with other professionals.

The Poisoning of Our Ozone essays

The Poisoning of Our Ozone essays The poisoning of the Earths ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozones depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem Ozone is a pale blue gaseous form of oxygen, in chemical form it is also known as O3. Ozone can be beneficial or harmful depending on its location in the Earths atmosphere. If the ozone is located in the troposphere (which extends from the surface of the Earth up to approxiametly10 miles) it is a harmful pollutant and a major component in smog and other environmental health problems. Such tropospheric ozone can damage plastic, rubber, plant and animal tissue. Ozone located approximately 10-25 miles above the Earths surface, in a part of the Earths atmosphere called the stratosphere is very beneficial. The ozone is a major factor that makes life possible on Earth. About 90% of the planets ozone is in the ozone layer. Ozone in this layer shields and filters out the Earth from 95-99 percent the suns ultraviolet radiation. A low level of ozone does not protect or prevent the ultraviolet rays from reaching the surface of the Earth, therefore, overexposing life on Earth causing many diseases. The depletion of the ozone is caused by many factors, but the one cause that will be elaborated on in the next paragraph is the main reason our ozone is continuously being poisoned. The major cause in the depletion of the Earths ozone layer is because of the release of chlorof...

Sweden Politics

Sweden Politics The first words of Sweden's constitution, the Grundleg, state that all public power in Sweden comes from its people. This is very obviously saying that Sweden is a democratic nation. This democracy is based on parliamentarism, meaning that confidence and support from the parliament, the Riksdag, are required for making all major decisions. If the cabinet (sometimes called simply the Government) does not receive support from a majority in the Riksdag then it may be forced to resign before its term has expired. This parliamentary system has been unicameral since 1970 and contains 349 members. These members are elected every four years. These three details (Grundleg, Riksdag, and the democratic system) are the basis of Sweden's political system. Nearly all of its politics can be traced back to these basic principles.The Grundleg is split into four different laws. They are called the Instrument of Government (Regeringsformen), the Act of Succession (Successionsordningen), the Freedom of the Press Act (Tryckfrihetsforordningen), and the Fundamental Law on Freedom of Expression (Yttrandefrihetsgrundlagen).A commemorative coin of the 150th anniversary of t...These laws serve as a basis for how Sweden is ruled. They also serve to protect the citizens' freedoms and rights and were revised from their original rendition in 1975 in order to keep up with changed issues.The Instrument of Government contains much valuable information. As I have stated it starts with the statement, "All public power in Sweden proceeds from the people." Another statement in the Instrument of Government is, "The king or queen who occupies the throne of Sweden in accordance with the Act of Succession shall be the head of state." This tells us that Sweden is still technically a monarchy and the king is the Kreifels 2 head of state but he no longer holds any authority in the governing of the state. His task...
