ABSTRACT Nowadays, conventional software development methods have gradually been replaced by agile software development methods. This phenomenon is mainly due to the conventional methods’ shortcomings, including a slow adaptation to rapidly changing requirements, and a tendency to be over budget and behind schedule. This paper analyzes objectives, strengths, and weaknesses of both conventional and agile methods. This paper also briefly explains the Unified Process, and the common elements of the Scrum process. Finally, this paper suggests a new Component Integrated software development process that combines the Rational Unified Process with the Scrum process to accommodate the strengths of both methods while suppressing their weaknesses.†¦show more content†¦One system development methodology is not necessarily suitable for use by all projects. Each of the available methodologies is best suited for specific kinds of projects, based on various technical, organizational, project and team considerations. Conventional heavyweight, document-driven software development methods can be characterized as extensive planning, codified process, reuse, heavy documentation and big design up front. These are some reason that conventional methods have been replaced by lightweight agile software development methods mostly in small-scale and relatively simple projects. This phenomenon is mainly due to the conventional methods’ shortcomings, including a slow adaptation to rapidly changing business requirements, and a tendency to be over budget and behind schedule The conventional methods also have not able to provide dramatic improvements in productivity, reliability, and simplicity. Despite the existing shortcomings, the conventional methods are still widely used in industry, particularly, for large-scale projects. Conventional methods come with their straightforward, methodical, and structured nature, as well as their capability to provide predictability, stability, and high assurance.

ABSTRACT Nowadays, traditional software processes have slowly taken the place of agile software Processes. This is mostly because of traditional processes have limitations, which holds a slow modification to quickly changing requirements, and a proclivity to go over cost of project and get late back in schedule.

PRD Therapy Psychoacoustic Disarticulation Reprocessing

Question: Discuss about thePRD Therapy for Psychoacoustic Disarticulation Reprocessing. Answer: 1st Part The six principles of scientific thinking are used in defining something as scientific or unscientific (James, 2012). In the case study, the researcher focuses on phobia and its reduction in human beings. They argue that fear is the cause of negative thoughts on individuals. In their opinion their newly invented therapy, Psychoacoustic Disarticulation Reprocessing can offer remedy to this situation. The central claim here is that fear is the cause of negative thoughts and reduction of fear in individuals can reduce negative thoughts. Replicability in research refers the probability of research to produce similar results in studies of the same type. It means that a research conducted involving some individuals today can produce similar results if the exact study is repeated at a later date ( Dienes , 2008). For a research to be termed as scientific therefore, its findings have to be replicable provided that the research remains just the same. The study analyzed in this case had a sample population of Caucasian adults between the ages of 18 and 35.The doctor and his colleagues repeated this study twice and got similar findings. Based on the fact that the findings were replicable in two independent but similar studies the research can be said to be reliable. However, reliability of these findings will depend on the angle from which we look at the study. If the focus was only on the members of the Caucasian family, the findings can be said to be reliable because the sampled population of two hundred and fifty adults provided similar results on two occasions. However, while the sample can be said to have been representative because it involved a large age margin, it was only focused on members of the Caucasian group. This means that its reliability outside this group of people cannot be established because the ease of influencing people may vary based on their attributes such as race. One of the warning signs related to pseudo-scientific claims is Overreliance on anecdotes. This emphasizes on the importance of statements to be supported by data gathered from a study instead of opinions from individuals because a single persons observation may be prejudiced or lack the merit that is required to represent the whole group. The study analyzed was conducted by doctor Zoosk and a number of other individuals .This means that then opinions were not based on the opinions of a single individual. Similarly the findings were based on a two studies involving 250 adults. This signifies the fact that the study was based on evidence and not mere imaginations or statements from the doctor and his colleagues. 2nd Part The core business of any research is to come up with findings that are reliable and which satisfy the objective of the research. This makes important every aspect of the research including the methods used and other factors considered in the research. There are different aspects of research methods that are used they include, representativeness of the population sample, use of a control group, ethical considerations among others. Control group in research refers to the group in an experiment that is not subjected to any form of treatment and which is used as the standard for assessing the change brought about by the treatment .Comparing the control group with the treated group enables a researcher to easily note the changes that are brought about by the treatment. A control group therefore forms an important component of research if the researcher intends to come up with reliable research findings. Based on the case study, researchers have concluded that PRD therapy can reduce anxiety levels in people and make them more happy and positive. However these findings could have been more reliable if there was a control group that could have been used in the study. The control group would have helped in establishing the actual changes without any assumptions, making the research more reliable. Additionally, representativeness in a population sample is very important. This helps in establishing uniformity in the research findings. On the other hand if the sample used in research is not representative of the wider group the research findings will be referred as unreliable. The research sample used in this study involved 250 Caucasian Adults between the ages of 18 and 35. The findings were therefore limited to only this definition of people. This can therefore be referred to as a biased sample .The danger of using a biased sample is that the findings arrived at might not be representative of people outside this group. The researchers emphasis on only members of the Caucasian may have affected the findings .The findings were also only applicable to people within the ages of 18 and 35 .The people belonging to other age brackets were left out as well .The researchers would have made their research more reliable if they used a sample that was representative enough.

To Kill or Not to Kill Essay Example

To Kill or Not to Kill Essay CAPITAL PUNISHMENT: TO KILL OR NOT TO KILL Student: Dave Cameron Professor: Robert Ashley Class: CAN271FA Law The Citizen The first record of capital punishment in Canada is that of Peter Cartcel, a sailor who murdered Abraham Goodsides, a sailor from another ship, in 1749. Peter Cartcel was found guilty of murder and sentenced to death by hanging. Capital punishment was first implemented in Canada in 1749 when it was under British rule as a British colony. The death penalty was not abolished in Canada until 1976. The last instance of Capital punishment was an execution that took place at Toronto’s Don Jail on December 11, 1962. Arthur Lucas, a man convicted of killing an FBI informant and Ronald Turpin, a petty thief who shot a policeman while fleeing a restaurant robbery, were the last two individuals to be hung in Canada. Over the course of the two centuries that Capital punishment was in use in Canada, 710 individuals were executed. Canada should not re-instate the death penalty for any offences due to the fact that the legal system is still not an exact science and many innocent individuals continue to be wrongfully accused of crimes.

If Canada reinstates the death penalty, there is a possibility that many individuals will be executed for crimes they did not commit. While there are no known cases of wrongful executions in Canada, between the years of 1879 and 1960, 438 death sentences were commuted as a result of newfound evidence etc. Had those 438 death sentences not been commuted, it is possible that 438 innocent Canadian citizens would have been put to death. Despite the fact that there is no evidence of wrongful executions in Canada, there have been many cases of individuals who have been exonerated of their crimes years after they were executed in other nations. One infamous case of wrongful execution occurred in the United States. Claude Jones, a United States citizen, was executed in the year 2000 for murdering liquor storeowner Allen Hilzendager in 1989. In 2007, a DNA test revealed that the strand of hair that was used by the prosecution to convict Claude Jones was actually a strand of hair belonging to the victim, proving Claude Jones’ innocence. Similar to Claude Jones’ proven innocence years after his execution, there have been many wrongful executions in other nations throughout the world. In the United Kingdom, Timothy Evans was found guilty of murdering his wife and daughter in 1950. The serial killer John Christie in fact committed the murders. The police coerced Timothy Evans into a false confession. The police also did not do a proper search of John Christie’s property and failed to find other human remains. Timothy Evans was granted a royal pardon in 1966, however an innocent life had been needlessly taken. Capital punishment was abolished in the United Kingdom partly because of Timothy Evans wrongful execution. If Capital punishment did not exist in these nations, the lives of many innocent men and women would have been spared. Therefore, Capital punishment should not be reinstated in Canada because it is not worth the possibility that innocent Canadians will be put to death for crimes they did not commit. If an individual is wrongfully accused for a crime, incarcerated for life and are exonerated, they can be released and resume their former life. However, a wrongful execution cannot be undone or taken back, it is permanent. It has been proven throughout the history of modern of law, particularly throughout the history of English common law, which is the basis of the Canadian legal system in every province in Canada except for Quebec, a province where they practice Civil law, that 50% of eyewitness testimony is false. Eyewitness testimony is the most influential deciding factor for a Jury during trial and 95-100% of crimes that carry Capital punishment are trails with a Jury. Therefore, there is a very high risk that innocent individuals will be put in jail and sentenced to Capital punishment based on a Jury swayed by false eyewitness testimony. Capital punishment has been used by nearly all nations throughout the world at one point in history. The use of Capital punishment as part of the justice system began with recorded history and it has made many changes and advances over the millennia that it has been in use. To its credit, there have been many movements towards more humane forms of execution, especially throughout the last century. Prisoners are no longer being boiled to death, crucified or impaled, however execution as a form of punishment is still seen as a gruesome act by many countries, including Canada. The more humane forms of execution that have been invented and implemented in modern jails include the electric chair, the gas chamber and lethal injection. These forms of â€Å"humane† execution are used in the United States where Capital punishment is legal. Many societies with Capital punishment ascribe to the Biblical Old Testament form of law, the idea of an eye for an eye and a tooth for a tooth, where a person who has harmed another should be similarly harmed in retribution. However, if you take an eye for an eye every time someone is wronged, the whole world will go blind. Another disadvantage to Capital punishment is that one of the purposes of jails in modern society is to rehabilitate inmates. Jails do not only exist to protect society from criminals that can harm the innocent, they also have the intention of rehabilitating inmates so that they can rejoin society as healthy, functioning members who can contribute in a meaningful way. There are many different types of rehabilitation programs established in Canadian prisons. One important rehabilitation program gives inmates access to educational services that they did not receive prior to their incarceration for various socio-economic reasons. These educational services allow inmates, who are often lacking basic education, to become literate, receive their General Education Development diploma, participate in vocational education programs, earn College diplomas and earn University degrees. One of the leading causes of crime is poverty, which is often caused by a cycle of illiteracy and a lack of education. Inmates should be given a chance to be educated while serving their sentence so that they can be rehabilitated into society, rather than being executed. When Capital punishment is in place in a nation, no societal progress can be made. Thousands of lives are taken and no change is made, the cycle of crime continues. Another leading cause of crime is drug and alcohol abuse. Many individuals resort to crime to support their expensive drug and alcohol habits and the majority have not received drug treatment prior to their incarceration. Another important rehabilitation program in Canadian prisons is the drug treatment program. Studies have shown that inmates who are required to participate in drug rehabilitation programs combined with therapy show positive results. The purpose of jails is to not only punish criminals, but to rehabilitate them into society. Inmates need to be given a chance to receive the rehabilitation they need, such as drug and alcohol treatment and an education before their lives are taken away. The solution to crime in our society is not Capital punishment. It is finding the source and the root of the crime, such as poverty, lack of education and drug and alcohol abuse and solving these problems and rehabilitating these individuals. Once inmates are successfully rehabilitated the level of crime will greatly diminish and no lives need to be taken in the form of Capital punishment. There are numerous disadvantages to reinstating Capital punishment in Canada, however one of the advantages to Capital punishment is it costs less money to execute a prisoner than to house them for life. In Canada, rather than receiving the death penalty for crimes such as murder, individuals receive 25 years in prison without the possibility of parole for the duration of those 25 years. It is possible that these individuals will remain in prison for the rest of their lives. If the crime is particularly heinous, the prisoner is designated a dangerous offender. This makes the possibility of parole much more difficult to obtain. Prisoners can also be designated long-term offenders. This is less serious than being designated a dangerous offender, however it is still difficult to receive parole. The designation of dangerous offender and long-term offender are made after individuals are convicted. The prisoners only given these designations once they have received a fair trail. Prisoners such as long-term offenders and dangerous offenders who remain in jail for 25 or more years cost Canadian tax payers and the Government an enormous amount of money. One advantage to Capital punishment is it’s financial benefit to the nations that implement it. The annual cost of housing an inmate in Canada can range between $52,000 to $250,000 a year depending on level of security of the facility in which the inmate is being held. Multiply that figure by the 25 years an inmate serves when sentenced to life in prison instead of receiving Capital punishment and the housing of an inmate for life in Canada ranges from $1,300,000 to $6,250,000. It is Canadian taxpayers who pay for the housing of inmates through the Government. However, the financial benefit of killing individuals instead of housing them for life is not worth potentially killing the innocent. There are many advantages and disadvantages to Capital punishment, however it should not be reinstated in Canada. The disadvantages far outweigh the advantages and it is simply not worth the possibility of potentially killing innocent individuals just to save the taxpayers and the Government money.

Sample Expository Essay - Helping You Write Better Essays

Sample Expository Essay - Helping You Write Better EssaysWhen writing an essay, using examples from reality is a really effective way to provide information. One of the main advantages of an expository essay is that you can provide real world examples that are easy to understand. This makes it much easier for people to grasp what you are saying and to determine whether they like what you are saying or not.There are many different types of expository essays and while the use of examples from reality is one of the most common, there are other more complex strategies that you can use when writing. One of these is to use samples from media and news reports.Newspaper articles have a really long list of all the latest developments in their respective industries. These news items will be very similar to the events that you are reporting on, so you should be able to come up with some very interesting examples to use. The next option would be to use pictures and photographs. It may seem that you are writing about a very specific event or particular place, but actually there are numerous examples to use in your essay.To use the example of a baseball player, we would include something like, 'As a result of his sheer dominance over his opponent's he is now the highest paid athlete in the world.' You should also include one of the other most famous examples, 'George Burns was also known as the man who always seemed to have a camera on him at all times.'It is not just about one sports star, it also applies to high end restaurants. You should be able to provide enough examples to make the reader start wondering if this is something that they have been doing for a while. It is also good to mention some of the other famous figures who also lived or worked at one of these places.Writing in this manner can be a challenge because it isanother writer's stereotype that is usually applied to us. We are expected to be able to describe such facts in such a straightforward manner and th us making it even harder for the reader to decipher between reality and fiction. However, as you learn to write like this, you will find that the examples start to flow more naturally and you can write more in an entertaining manner.Even though you use sample expository essays and examples from media and news, these should not be the only things that you use. There are still many other different sources of information and you can include other kinds of articles in your essay.

Yousuf Karsh, photographer essays

Yousuf Karsh, photographer essays Youseph Karsh was a world-renowned photographer, famous for his photographs of dignitaries and political figures. Karsh was born in Turkish Armenia in 1908. At the age of 14 he and his family fled to Syria to avoid the genocide being committed in Armenia. At 16 years of age his family sent him to Canada to live with his Uncle who was a portrait photographer. When he was 20 his uncle sent him to Boston to study photography with John Garo, who was considered one of the top ten portrait photographers in America. What was to have been a six-month apprenticeship lasted three years. Karsh was exposed to famous people from the world of music and theatre and he decided that when he branched out on his own he would only photograph those men and women who leave their mark on the world. In 1932 Karsh moved back to Canada and opened his photography studio in Ottawa, there he caught the eye of Canadas Prime Minister, Mackenzie King. King set him up to photograph political figures. In 1941 King arranged for Karsh to photograph Winston Churchill, who was visiting Canada, Churchill had not been notified he was having his portrait made until he was being ushered into the room. Grumbling, he lit a cigar and told Karsh he had exactly two minutes to take his picture. Karsh, knowing he did not have adequate time to get a good photograph, calmly walked over to Churchill, plucked the cigar from his mouth, and saying, forgive me sir, released the shutter. Afterward Churchill told Karsh You can even make a roaring lion stand still to be photographed. Karsh sold this photograph to Life magazine for $100. It has become the most reproduced portrait in American history. Karshs goal when photographing someone was to expose the essential element which has made them great, explaining, All I know is that within every man and woman a secret is hidden, and as a photographer it is my task ...

How to Use Loops in Ruby Programming

How to Use Loops in Ruby Programming Computer programs often have to perform actions a number of times, not just once. For example, a program that prints all of your new email will need to print each email from a list, not just a single email. To do this, constructs called loops are used. A loop will repeat the statements inside it a number of times until some condition is met. While Loops The first type of these loops is a while loop. While loops will execute all of the statements contained within them as long as the conditional statement remains true. In this example, the loop continually increases the value of the variable i by one. As long as the conditional statement i 10 is true, the loop will continue executing the statement i 1 which adds one to the variable. #!/usr/bin/env rubyi 0while i 10i 1endputs i Until Loops Until loops are almost identical to while loops except that they will loop as long as the conditional statement is false. The while loop will loop while the condition is true, the until loop will loop until the condition is true. This example is the functional equivalent of the while loop example, except using an until loop, until i 10 . The variable is incremented by one until its value equals ten. #!/usr/bin/env rubyi 0until i 10i 1endputs i Loops the "Ruby Way" Though the more traditional while and until loops are used in Ruby programs, closure-based loops are more common. It isnt even necessary to understand what closures are or how they work in order to use these loops; in fact, theyre viewed as normal loops despite being very different under the hood. The Times Loop The times loop can be used on any variable containing a number or used on a number itself. In the following example, the first loop is run 3 times and the second loop is run however many times is input by the user. If you input 12, it would run 12 times. Youll notice that the times loop uses the dot syntax (3.times do) rather than the keyword syntax used by the while and until loop. This has to do with how the times loop works under the hood but its used in the same way a while or until loop is used. #!/usr/bin/env ruby3.times doputs This will be printed 3 timesendprint Enter a number: num gets.chomp.to_inum.times doputs Ruby is great!end The Each Loop The each loop is perhaps the most useful of all the loops. Each loop will take a list of variables and run a block of statements for each of them. Since almost all computing tasks use lists of variables and have to do something with each of them in the list, the each loop is by far the most common loop in Ruby code. One thing to note here is the argument to the loops block of statements. The value of the current variable the loop is looking at is assigned to the variable name in pipe characters, which is |n| in the example. The first time the loop runs, the n variable will be equal to Fred, the second time the loop runs it will be equal to Bob and so on. #!/usr/bin/env ruby# A list of namesnames [ Fred, Bob, Jim ]names.each do|n|puts Hello #{n}end
