Assignment Module 1 –Case Study 1 Chapter 3, Case 1: Advance America Implements Grid Computing Critical Thinking Questions
1. Why is the new grid computing system at Advance America much easier to install, manage, and maintain than its old system?
In the older system of Advance America each of the centers had their own software and hardware installed in their premises, and every night all the centers around the country you to send their data to the main hub. Because of the growing numbers of the data and the centers around the country there was not enough time for all the data to be transferred to the main system plus the maintenance cost of the older system was much higher.
In the new system Advance America switched to grid computing. “Grid computing is the collection of computer resources from multiple locations to reach a common goal.”{1}
They installed a Client machine in every center which connects to the Web from a fault-tolerant server running Oracle database software. In this process may computers are working together to reduce the workload over the server which in turn helps in identifying and solving the problems much quicker even in real-time.

2. How might Advance America expand its system as the company outgrows it?
Advance America is combining Oracle and a third-party database in to a centralized database. “Oracle Database 10g, and is using Oracle Real Application Clusters to distribute their workload across multiple servers to help ensure 24x7 uptime and the ability to easily scale as centers are added.” {1} David Toothman, Chief Information Officer said that by using Oracle Database 10g and Oracle Real Application Clusters it will enable them to meet their IT systems needs and will also help in opening new centers and making more transactions.{2}

Chapter 3, Case 2: Mayo Clinic Turns to Game Processor to Save Lives 1. In what other industry and scenario might time play an important role when it comes to processing? Explain how reducing minutes to seconds has an impact in that scenario.
Time plays an important role in the medical industry. Every decision taken can save a life. We know that Doctors and radiologists have to interpret images day in, day out and a standard computer processor is not able to interpret the result much faster.
With the help of companies such as IBM, Sony and Toshiba they were able to specially design a cell processor which will enhance the speed at which the images are analyzed. They believe that the difference in time would be from 10 min to a short as four second. With the use of this cell processor it would help in comparing the scan images of a patient over time.
Example: A patient who is having a tumor, a standard PC would take several minutes to come up with a result. But with the use of a cell processor it would be done in seconds. This can ease a lot of work load on the physicians.

2. What other processing technologies presented in this chapter might assist the Mayo Clinic in speeding up its computations?
So of the technologies that can be used in assisting the Mayo Clinic in speeding up the calculation is Multiprocessing, Parallel Computing and Grid computing.
Multiprocessing:
Executing two or more instruction at the same time is called Multiprocessing. Giving different commands to different coprocessor chips helps in getting the work done faster and more efficiently.
Parallel Computing:
Giving the same task to different processors to get the result faster is called Parallel Computing. In this method the processor communicates with other processing system or work individually to find the solutions faster.
Grid Computing:
Grid computing uses other computer which might be owned by other organizations to work hand in hand to find the solution to the problem. It is also a cost efficient method to Parallel Computing.

Chapter 4, Case 1: Systems Management Software Helps Fight Crime 1. What other types of industries would benefit from products like Microsoft System Center Configuration Manager? Why?
“Microsoft System Center Configuration Manager is a Windows product that enables administrators to manage the deployment and security of devices and applications across an enterprise.” {1} “The use of Microsoft System Center Configuration Manager can benefit different IT companies in many ways such as * Asset Management- It will help in keeping a track on licenses computer and hardware in DMV. * Security team- Keeping a check on all the computers for updates and glitches for a company with the desired configuration management so that it could identify if the computer is up to the security standards of the company. * IT Management – Reports on security, hardware and licenses.” {2}

2. What general lesson regarding information system administration can you take from this case?
You can see from this case study that with the use of technology in the right place every work load time can be reduces. With the use of right management system software the pork of the officers and the IT employees was reduced by a great extent. The officers no longer had to wait in the offices for the system to get updated. The information was given to all the notebooks at the same time with the use of right management system.

Chapter 4: Case 2: Energy Giant Valero Turns to SOA Software 1. Why is it important to maintain a reasonably sized catalog of services rather than a large amount of services?

...This case study is an excellent example of how different types of parties can be brought together in a large scale transaction and how the original energy of those early meetings can be lost over time. I imagine that when Anthony Athanas was purchasing those old piers back in the 1960s many, if not all, of his colleagues, friends, and family members told him that he was off his rocker. I’m sure Athanas was looking at this land as his family’s ticket to financial prosperity and somewhat of a legacy that he could leave to his descendants for years and years to come. One of the items I wish the case would have divulged is the amount of money that Athanas had invested in the properties. For me this information would have given an insight to his net worth and how much he had riding on this investment. I assume it was substantial given his actions later in the process. Twenty years later Athanas’ dreams came true and all those naysayers were more than likely green with envy. The amount of pride Athanas’ had in his investment at that moment had to have been insurmountable. Being approached by a big time real estate development company and their extremely wealthy client, Hyatt Corporation, must have made Athanas feel larger than life and made him feel like something he isn’t, which is a developer himself. The case doesn’t give much insight into whether Athanas had any representation or anyone consulting him throughout the process. From the beginning, I saw this as matchup...

Case Study

...Yin (2005) suggested that researchers should decide whether to do single-case or multiple-case studies and chose to keep the case holistic or have embedded sub-cases. This two-by-two combination can produce four basic designs for case studies. When selecting a case for a case study, researchers often use information-oriented sampling , as opposed to random sampling [3]. This is because an average case is often not the richest in information. Extreme or atypical cases reveal more information because they activate more basic mechanisms and more actors in the situation studied. In addition, from both an understanding-oriented and an action-oriented perspective, it is often more important to clarify the deeper causes behind a given problem and its consequences than to describe the symptoms of the problem and how frequently they occur. Random samples emphasizing representativeness will seldom be able to produce this kind of insight; it is more appropriate to select some few cases chosen for their validity. But this isnt always the case. Three types of information-oriented cases may be distinguished: Extreme or deviant cases Critical cases Paradigmatic cases. [edit]Critical case A critical case can be defined as having strategic importance in relation to the general problem. For example, an occupational medicine clinic wanted to investigate whether people working with organic solvents suffered brain damage. Instead of choosing a representative sample among all those......

...A Case Study by any Other Name Cathy Foster Liberty University   A Case Study by any other Name Researchers have different methods of observing their subjects. Among the most popular is the case study. Case studies are used a lot in psychology and one of the most famous psychologists that used case studies to detail the private lives of his patients was Sigmund Freud. What is a Case Study? “A case study is an observational method that provides a description of an individual” (Cozby & Bates, 2012). During a case study the individual is usually a person however that’s not always the situation. The case study can also be a setting, which can include a school, business, or neighborhood. A naturalistic observational study can sometimes be called a case study and these two studies can overlap (Cozby & Bates, 2012). Researchers report information from the individual or other situation, which is from a “real-life context and is in a truthful and unbiased manner” (Amerson, 2011). What are some Reasons for Using a Case Study Approach? There are different types of case studies. One reason to use a case study is when a researcher needs to explain the life of an individual. When an important historical figure’s life needs explaining this is called psychobiography (Cozby & Bates, 2012). The case study approach help answer the “how”, “what”, and “why” questions (Crowe, 2011). What are Some Advantages and Disadvantages to the Case Study Approach? Some......

...Case Study The case study of a 6 year old boy, who brought a gun to school and shot a first grade classmate, then was later found hiding in a corner, has brought multiple psychological issues to the forefront. According to the law a child under the age of 7 is not criminally responsible. The prefrontal cortex of the brain is the area where high-order cognition, planning, goal-directed behavior, impulse control and attention are centered. This portion of the brain is not considered mature until much later in life. The Limbic system of the brain controls and regulates emotion and contains three parts: the amygdala, the hippocampus, and the hypothalamus. According to researchers, the amygdala is the portion of the limbic system that registers emotions, especially fear (LoBiondo-Wood & Haber, 2010, p. 214). According to this fact, high levels of fear and stress negatively affect other areas of the limbic system including the hypothalamus, which is responsible for activating hormones that produce responses from other brain and body parts as well. An overproduction of hormones can cause permanent damage to learning and memory. Perseveration is a tendency to stick to one-thought or action. This, along with impulsiveness is believed to occur in children with still immature prefrontal cortex as well. This is evidenced by temper tantrums, and immature emotional responses to name a few. From a cognitive developmental standpoint, according to Jean Piaget, a 6 year-old is on the...

...for the achievement of sustained competitive advantage. Your discussion is to be based on three suitable published case studies. This means case studies published in the academic literature – for example, the series of case studies in the textbook or in equivalent textbooks. You may not use Yahoo! as one of the case studies and short articles in newspapers, magazines, website opinion pages and the like are definitely not acceptable, although such materials may be used to supplement the published case study and your analysis. All sources must be properly referenced. If in any doubt about the suitability of a case study, seek an early ruling from your tutor. This is a substantial piece of scholarly work and will require extensive engagement with both unit theory and at least three detailed case studies. Process: 1. Choose your three cases. They all need to be published cases in academic sources (e.g. textbooks, journal articles). It is obviously important that each case represents an instance of a company achieving sustained competitive advantage (check your materials to be clear about what that means). 2. Analyse and locate evidence. Begin to analyse each case in terms of the two questions – particularly question one. It is vital that you respond to both questions, but the evidence for sustained competitive advantage is more likely to be in the case material itself.

...Running Head: Case Study 1 Case Study #1 Clinical Psychology: Severe Depression Princess Coles ABS 200 Introductions to Applied Behavioral Sciences Instructor Weniger 08/4/2015 Severe depression is one of the many mental illnesses that affect one out of ten Americans. Severe depression involves, extreme or constant feeling of sadness, loss of interest in activities and even relationships. Those suffering from depression might even struggle with the feeling of worthlessness and repeated thoughts of suicide. Therefore the effects are not only psychological but physical as well. According to Kessler author of Twelve-month and lifetime prevalence and lifetime morbid risk of anxiety and mood disorders in the United States International Journal Of Methods In Psychiatric Research, (3), 169. About 17% of people are likely to experience some kind of depression at some point in their lives. I have chosen this topic of interest because it is important to help those suffering from depression understand that there is help and that with treatment they can lead a more positive way of thinking. Some mental health problems are caused by dysfunctional ‘ways of thinking’-either about self or the world (e.g. in major depression) and many anxiety disorders are characterized by a bias towards processing threatening or anxiety relevant information. Cognitive behavioral therapy is generally perceived as an evidence based and cost effective form of treatment that can...

...Case Study Complete Case History The patient in this case study reports being ‘sick with flu’ for 8 days. She has been vomiting, and cannot keep any liquids or food down. She also reports that she has been using antacids to help calm the nausea. After fainting at home, she was taken to the local hospital, severely dehydrated. Upon looking at her arterial blood gas result, it would appear that this patient would be suffering from metabolic alkalosis. This patient’s pH is greater than 7.45 (normal: 7.35-7.45) and her bicarbonate (HCO3) is greater than 26 (normal 22-26). Blood gases indicate that case study patient is suffering from hypochloremic metabolic alkalosis. Focused Assessment The case study patient reports being “sick with flu” for eight days. She reports vomiting several times a day and taking more the recommended dose of antacids. She reports that she fainted today at home and came to the hospital. The case study patient reports that this all started approximately eight days ago. The case study patient also reported taking excess amounts of antacids. Ingesting large amounts of this medication can cause metabolic alkalosis. When antacids are taken in large doses, the ions are unable to bind, and therefor the bicarbonate is reabsorbed and causes alkalosis (Lehne, 2013). Renal and Respiratory systems response Hypochloremic Metabolic alkalosis occurs when there is an acid loss due to prolonged vomiting which causes a decrease in the extracellular...
