Empirical Evaluation in Software Engineering Essay

Empirical Evaluation in Software Engineering - Essay Example The systems developed are inherently complex by nature not to mention that they are constantly changing and this has in a large part required empirical evaluations to be carried out especially with regards to the large systems so as to incorporate continuity. Question 2 What factors might make it difficult to conduct an empirical evaluation of the scenario? Explain five factors and relate each of them to the scenario. There are several factors that might make it difficult to conduct an empirical evaluation in this scenario. They include: i. The researcher’s inexperience. The complex nature of carrying out such tasks requires one to have experience in this field. In this scenario, the person concerned has not even studied this subject and this coul prove to be a mjor stumbling block. ii. Inadequate resources. In order to carry out an empirical evaluation, large amount of resources are required. In our scenario, it might not be possible to acquire adequate funding to carry out s uch a project and therefore transforming theory into reality via empirical evaluation might not be possible. iii. Cumbersome. ... v. Inadequate information.Another difficulty might come about when seeking further information with regards to the two methods. There is very little information on the matter as there has been little or no reaserch done cocerning this. Question 3 Using the Fenton and Pfleeger model, why is it hard to show that an lntegrated Development Environment (such as those stated in the scenario) leads to improvements in the software project, or in the quality of the software produced. The end product in software production is greatly dependent on two factors; the experience of the developers and the input applied to the development process. A high quality software at the end of the day should do what it was intended for but in a simpler manner and for this to come to fruittion, it depends largely on the design principles and the developer. The Integrated Development Environment lays more emphasis on the ease of use, manageability and user interfaces. This makes it more difficult to evaluate th e importance of determining the quality of the controls, resources and input since they are determined by the developers. Further, in order to determine the output, provision of empirical evidence is key so as to predict it. Coming back to our scenario, this is not practical because of the complexities and numerous functionalities of the environments (Lewis & Veerapillai 2005) Question 4 Critically discuss the benefits and limitations of the case study and the survey study to answer'- the friend's question. There are many benefits that can be realised through conducting a case study method in the evaluation process. Some of these benefits may include; quantifying of the various benefits and functionalities that may be realised in a single

The Effects of Diabetes on Aging Adults Research Paper

The Effects of Diabetes on Aging Adults - Research Paper Example This paper gives an understanding of diabetes in older adults and the needs for nutrition, exercise and care. The Effect of Diabetes on the Aging Adult As adults age, there are many factors that they must take into consideration to make sure that they age gracefully. Many adults find that as they age, they are met with issues that they may not have had when they were younger. As an example, adults who are not active will sometimes run the risk of arthritis and other bone or joint ailments. Their doctor may tell them that they must continue to do exercise because it will help some types of arthritis. Adults can also find that they gain weight easier or that weight is more difficult to take off as they grow older. These are natural aspects of aging, but they do not have to be long lasting. In looking at the area of nutrition and aging, this researcher has chosen to study the idea of diabetes in the aging population. Defining Diabetes Type 2 diabetes also known as adult onset diabetes, is a chronic condition and it affects the way that the body processes sugar or glucose, which is the body's main source fuel (Mayo Clinic, 2011). Basically, this means that a person's body has a resistance to the hormone insulin that is responsible for moving glucose through the body. Some people do not produce enough insulin to maintain a glucose level within normal ranges. Both of these conditions are a product of Type 2 diabetes. Although there is no cure for the disease, there are many ways that an individual can manage it. There are many symptoms that people may ignore because they may not create a problem for them. These symptoms include: 1. Increased thirst and/or frequent urination -- this happens when sugar builds up in the bloodstream. Fluid is taken from the tissues to compensate and this can result in the individual becoming very thirsty. 2. Increased hunger -- the muscles and organs lose energy when they do not have enough insulin and this increases hunger. 3. Lose of w eight -- many people lose weight because the body does not use glucose properly. The body will use any fuel it can get which means it will look to what is stored in the muscles and fat. 4. Fatigue -- people with Type 2 diabetes often report that they are tired and irritable. 5. Blurred vision -- this is an indication that the sugar in the body is too high. When this happens, fluid is taken from the eyes so the vision is blurred. 6. Slow healing sores or frequent infections -- if this occurs it is best to talk to a doctor because it is a symptom that happens in people who have diabetes. 7. Areas of darkened skin -- people with Type 2 diabetes may find darkened areas in their armpits or around their neck. This could be a sign that the individual is resistant to insulin (Mayo Clinic). An individual is more likely to develop diabetes as they age if they fit into several categories: 1. They are over 45 years of age. 2. They have high blood pressure. 3. They are obese. 4. They have a fami ly history of diabetes and are African American, Hispanic/Latino, American Indian, Alaska Native, Asian American or Pacific Islander. 5. Have blood vessel problems that affect their legs, heart or brain. 6. Have abnormal cholesterol (lipid) levels. (National Diabetes Education Program). Demographics of Older Adults with Diabetes When an adult is experiencing any of these symptoms, it is important for them to go to a doctor to find out whether they have diabetes. According to

Early Childhood Studies Essay Example | Topics and Well Written Essays - 2750 words

Early Childhood Studies - Essay Example This paper stresses that the process of children with special needs is tied with the Reformation of Europe which saw the promotion of childhood as a unique state in a person’s life where s/he has to be segregated and taught things that will be beneficial to him or her in life. The Industrial Revolution did not come up with any rules and regulations that directly affect or influence children with learning disabilities. Thiis report makes a conclusion that the main framework of relevant laws today have its roots in the Education Act 1944 which sought to promote children with special needs’ requirements and their identification. Also, the institution of laws and regulations relating to the identification of children with special needs and helping them got a major boost with the Warnock Report which came up in 1978 and was implemented in the Education Act of 1981. These rules created a framework that supported the medical and physical assessment of children with special needs in order to keep them in special schools. These assessments were regulated and they were given various yardsticks and guidelines. The author approves that these rules were later modified by the Labour Government and this was complemented by the Human Rights Act 1998, which allowed the UK to create rules and regulations that relating to children with special needs that was in sync with the existing regulations. The SEN And Disability Act of 2001 was complemented by the 2004 SEN Strategy that was meant to remove barriers towards achievement and enhance investments into various charitable organisations that were focused on persons with disabilities.

Thomas Hobbes views on Hate Crimes Research Paper

Thomas Hobbes views on Hate Crimes - Research Paper Example In relation to this, aversion refers to the state of being repelled by the object that one hate and this refers to the presence of the object, which in turn leads to the hate for the object (Herbert 98). The above is a strong view on hate crimes in that it is based on this that he is able to place a distinct definition to depict the difference between love and hate, and how the two relate to one another. This is by definition of the presence and absence of all the aspects of an object or the object in its entirety to e hated or loved. As such, hatred is the presence of that which one would like to avert from, as well as the presence of aspects that are of negative appeal to the person in question. Hobbes view goes as far as stating that without the presence of order in an indefinite manner is likely to cause the perpetration of conduct and actions that people please to do. With this in mind, the crimes of hate are brought out in terms of the presence of order, in which case order is meant to restrict the general overview of hate in relation to aversion and the presence of undesirable elements in an aspect of an object or the object as a whole. As a result, Hobbes is of the view that laws or orders are the determinant of the perpetration of hate crimes, in which case they are used and are meant to act as restrictions towards people’s behaviors by constraining their desires (Vaughan 61). This is in relation to what they find pleasant or unpleasant, in which case order is the ultimate determinant of human behavior, where it dictates that which can be liked and to what extent. In addition, it determines what can be done and that, which cannot be done in relation to the hatred of the events that culminate in the hatred and what relates to the hatred occurring towards an object. As a result, Hobbes is of the view it is order that blocks unfavorable human conduct in relation to hate crimes making order the one way that hate crimes are avoided, and even eliminat ed altogether. In addition, the crimes of hate, according to Hobbes, morality is the main aspect that determines the application of love and hate, in which case, the two are based on being fit. As such, the fittest means to conduct life is termed to be the promotion of personal wellbeing, where this is the consequent of the derivation of morality from prudence (Replogle 571). This is to mean that Hobbes view on crimes of hatred is the presence of logic and morality to direct the behavior of a person as it is through logic, or rather reason that a person can direct him or herself in a responsible manner. Responsibility, according to Hobbes, is conduct that appealing to the logic of the social environment, in which case it is the social environment that determines the correctness and wrongness of one’s conduct (Michaelis 105). In addition, it is according to reason that crimes of hatred can be corrected as man can be shaped or influenced by the same environment to conform to it s moral standards, or even come up with his or her own moral codes that are based on prudence, reason and logic. As such, he brings up his view on the role of the society on influencing hate crimes, as a gauge for right and

Robots in Ophthalmology Article Example | Topics and Well Written Essays - 750 words

Robots in Ophthalmology - Article Example Sociologist Alvin Toffler may have travelled through time and witness the future when he said, "Technology makes more technology possible". He is right, as after thirty-seven years of rapid technological advancement here were are facing a what he called "abrupt collision with the future" (Toffler 1970), and practically living with these amazing technologies created to make life easier in our homes, built to run our industries, and designed to perform medical care to save lives. Technology in the medical field has come along way; molecular and biometrics, wave technology, nanotechnology, and robot aided surgery is now possible (Combs 2005). As nanotechnology makes it possible to build up materials and systems to produce new physical, chemical and biological properties out of existing common materials, robotics are all about computer controlled mechanical devices built to mimic human movements and intelligence (Woods 2007).Advanced robotic products such as surgical robots are now commo n in operating rooms of large medical centres, and it is recognized as a dynamic surgical tool for enhancing human surgeon's dexterity in less invasive surgical procedures Although their high cost prohibits general use, initial applications of these robots considerably prove their clinical benefits and surgical potential. In general, intelligent surgical robots main advantages are its ability to register medical images accurately, to move consistently without exhaustion and tremor, work in a hazardous environments unsuitable to human surgeons, and their ability to reposition instruments swiftly and precisely through complicated trajectories or on top of numerous targets. The precision and steadiness of these robots is what makes them ideal for surgical procedures particularly in delicate eye surgery (Webster and Li 2003). Although robots are precise and steady, there is no evidence that they can perform cataract removal surgery alone or perform any surgery independently. They merely serve as robotic mechanical arms for ophthalmologist performing remote surgery through a three dimensional virtual-reality console. With hands and head partly inserted inside the console, the surgeon moves his hands as if he is directly performing the surgery while the robot is simultaneously imitating the movement of the surgeons arm and physically performing the operation. Surgical robot now is more like an interventional piece of technology than a self-sufficient intelligent machine. For instance, the popular surgical robot, the da Vinci Surgical System (see Fig. 1), priced at more than one million dollar, is just a three arm (with 4th optional arm) mechanical machine equipped with a variety of electronic hardware who perform surgery by following instantaneous instructions from a surgeon while imitating his hands and ar ms movements. There is no known technology yet that is capable of virtually emulating a human surgeon's competence and senses particularly in the field of ophthalmology. Although ophthalmic surgery with a robot can increase precision, speed, and eliminate tremor, they do not have substantial or convincing advantage similar to robots in other surgical fields (Roach 2007). For instance, using the same da Vinci Surgical robot in heart surgery provides a better alternative to customary chest cracking technique, lengthy incision, bone cutting, and ripping of the ribs. Since "cutting people open is no longer the focus of modern surgery" ( Darzi 2007).The success rate of robot assisted closed chest surgery approach and less invasive surgeries shows significant positive results particularly in patient's health and quick recovery; since they do not have to endure the excruciating traditional surgery procedures with large incisions involved (Goldschmidt 2007). However, surgical robot in general is still in a transition stage and used primarily as a tool. They still do not have the capability and intelligence of a real surgeon who can perform surgery independe

PNEUMONIA Essay Example | Topics and Well Written Essays - 750 words

PNEUMONIA - Essay Example Pneumonia can make an individual very ill even to the point of death. However, the disease can transpire in young, as well as healthy individuals, but is more dangerous in older adults, babies and persons with other illness or weakened immune systems. Pneumonia is often caused by a bacterium, the Streptococcus Pneumoniae, especially in people who suffer from chronic obstructive pulmonary diseases and are victims of alcoholism. Such individuals are vulnerable to contracting pneumonia from Klebsiella, as well as Hemophilus Influenza. This category, although occurring temporarily, has some association with the bacteria known as the Mycoplasma Pneumoniae (Krause, 2012). Subsequently, the attacking organisms results in a variety of impact, in part, by irritating to an overly enthusiastic status to the immune responses within the lungs. Therefore, the small blood vessels within the lungs tend to develop leaks; hence, protein-rich fluid seeps through the alveoli. However, this tends to mark a less serviceable region for oxygen-carbon dioxide conversions; hence, the affected victims tend to develop oxygen rundowns while holding hypothetically risky carbon dioxide (Krause, 2012). Conversely, ill persons respire faster in conjunction to result in more oxygen, as well as release of more carbon dioxide. However, when these secretions are augmented, the leaky vessels often tinge the mucus with blood. The mucus plugs tend to diminish the efficacy of gas conversions within the lungs. Nonetheless, the alveoli tend to fill up with fluids, resulting in the debris from a vast number of white cells that get released to combat the infection (Krause, 2012). Therefore, the pneumonia condition often starts when an individual breathes the relevant germs into lungs. What follows is usually the disease after accessing a cold, as well as a flu. Conversely, the sickness will tend to make a person find it difficult for his/her lungs to fight against the

Historiography Paper on Rosa Parks Essay Example | Topics and Well Written Essays - 2000 words

Historiography Paper on Rosa Parks - Essay Example These not only shook its entity but went ahead to completely paralyze the company by rendering it completely bankrupt. Rosa was a figure that compelled the tough-headed racist leaders and society that had never imagined such a wimp of events to ever surface. This not only broke the yoke of perceived notion of white infallibility and invincibility but brought to the global knowledge a possibility of impossibilities. To even turn tables more, Rosa never demanded to be accorded any leadership totality of the move she was virtually the flag bearer, but instead was formally endowed by nature that a status was more of a symbolic and formidable personality. She poised to elevate the invincible role and significance of a virtuous black woman. Such was an elevated dignity and demeanor. There comes a unison move to see to the strengthening move by Rosa and this comes from the sentiments shared by Mary H., Gloria B. & Dale G., (2006). Alongside Rosa’s figure are seen other equally strong black women whose significant roles played the racial shaping moment in American context. The formerly disregarded black minors in the vast world class society were now regarded as the footnotes of the historical timeline. For a long time, there had been segregation in America on the rise; this was such a racial imbalance that men defied basic legislations in broad day for no fear of victimization. Philip S.,( 2007). Rosa Parks and her protest for civil rights, Cherry tree Books. US. For instance, an incidence of the 1944 which involved a defilement of a lady aged twenty four.

An incidence of the 1944 which involved a defilement of a lady aged twenty-four. This is the story of Racy Taylor; a sharecropper and a mother. On her way home from her routine prayers, she encountered a group of white men; specifically seven in number, armed with weaponry such as shotguns and hand knives. The seven men intimidated the young Alabama lady and compelled her into their green Chevrolet. The next she underwent was such an ordeal unforgettable. You can imagine a gang of seven raping a lone-lady especially after her time of spiritual nourishment, then leaving her for dead. As a matter of fact, the word spreads round thereby compelling the president of the then existing area NAACP to act quickly. His move was to send the smartest of his investigators and team leader to Abbeville. This investigator emerges to be Rosa Parks. In the event that Rosa undertakes to start off the case, she yields such a move that sparks off a great revolution in the world. This gives the account of the never before stipulated history, and how the movement by the civil rights was such prompt and focused to opposing the mounting segregation and torture that black women were subjected to by white men. This was to intimidate the blacks on economic grounds, freedom movement and sexual violence per se. In a way to stress on this fact Terri De Gezelle.
