Unit 2 Case Study 1:

B. Assuming Josephs heart has stopped, eventually the cells will die from the slowing of oxygen, blood glucose, and waste removal. The oxygen is needed for the reactions in the mitochondria. The cells work rapidly using up all of its ATP supply. The pH balance in the cells begin to drop and carbon dioxide builds in the cells, the carbon dioxide needs to be removed from the cells. The active transport pumps shut down the plasma membranes of Josephs heart.

C. All intracellular organelles have membranes as part of their strtucture, such as the endoplasmic reticulum, Golgi apparatus, mitochondria, and the nucleus. The breakdown of the membranes of these structures affect the function of Josephs heart cells. If the mitochondria membrane becomes damaged it cannot produce ATP. Some of the channels in the plasma membrane will not function without ATP. When the plasma membrane is damaged the channels will not work and there becomes an overload of substance in the cytoplasm.

D. The instructions Johsephs body needs to repair itself and his predisposition for vascular disease are both contained within the mitochondrial DNA and in the mRNA. The information that’s needed is help in the DNA, but is mainly held in the mRNA which works the synthesis of proteins that fix the body.

E. The types of proteins in the cell membrane that are involved in the homeostatic imbalances of his heart cells are the sodium, potassium, and ion channels. Without ATP they can not operate. Homeostasis can not be maintained within the body without proper function.

F. Reestablishing the oxygen flow to Josephs body was important because the body needs oxygen to survive. Without oxygen the body can not create ATP, when the chess compressions and the oxygen were given, his body was able to release C02. When the C02 was released…...

...Unit 2: Case Study - The North Face, Inc. Julia Harmon AC503 – Advanced Auditing Unit 2: Case Study – The North Face, Inc. Should Auditors insist that their clients accept all proposed audit adjustments, even those that have an “immaterial” effect on the given financial statements? Defend your answers. The auditor would not be able to insist that their client accept all proposed audit adjustments. The auditor must advise management, the Board of Directors and the audit committee of all proposed adjustments and advise them of what the effect of the adjustments will have on the financial statement. The omission or misstatement of an item in a financial report is material if, in the light of surrounding circumstances, the magnitude of the item is such that it is probable that the judgment of a reasonable person relying upon the report would have been changed or influenced by the inclusion or correction of the item. (SAB 99). If after determining if the omission or misstatement is material, then the auditor should insist the adjustment be made. If the client refuses, then the auditor should issue a qualified opinion. Should auditors take explicit measures to prevent their clients from discovering or becoming aware of the materiality thresholds used on individual audit engagements? Would it e feasible for auditors to conceal this information from their audit clients? No the auditor should not take explicit measures to prevent their clients from discovering or becoming......

Chapter 1 Case Study 2

...Chapter 1 : Case Study 2 Providing any form of compensation could be taken as an offense for thousands of donor families who have already made a benevolent choice of donating organs. The proposed legislation could also end up alienating families who have decided to donate life saving organs regardless of any compensation. Many may think that offering economic benefits, wether directly or indirectly in exchange for organ donations or assigning monetary value to the human body, or body parts, is inconsistent with our values as a society. The proposed legislation could also promote suicidal behavior in people who are in need of monetary help or want to help out their family and loved ones. By offering financial incentives, there could be an increase in crimes such as organ stealing and possibly murder for receiving money for the stolen organ. These are the few issues that this proposed legislation raises. Even though the proposed legislation raises the above mentioned issues, I would still support the the bill. Providing financial incentives for organ donation might seem like it diminishes human dignity, however, it could be something worth looking into. In the normal world, people are naturally resistant to things they are not familiar with or cannot relate to. Economic incentives might force them to rethink their options about organ donation. The proposed legislation may not deter people who believe it is wrong but, it will cause a large population to consider organ......

...Strategies for security in High-Rise Residential Buildings | November 10 2013 | | Kristen Mosuch Case Study 1 | Strategies for security in High-Rise Residential Buildings When living in a high-rise, residents have a reasonable expectation of safety and security. As a contractor charged with the construction of such a building, there are many facets of security that must be taken into consideration before design and construction can begin. As a contractor, there is a certain responsibility to account for any risks that already exist, as well as risks that may exist in the future. Security is often used as a selling point for potential buyers, so the overall success of the project can depend on how well the security portion is implemented. According to Chris Grniet, regional managing director for Guidepost’s Technology/Design Consulting team, “What’s secure and what isn’t for residential properties tends to wax and wane with the perception of general security and safety in the overall environment.” (Garris, 2013) Residents will feel more comfortable, and will be willing to spend more if they feel secure in their living environment. “When establishing the right mix of comfort and security, the trick is to incorporate security measures without making them completely obvious. It’s not about being stealth, but about providing a safe environment that feels like home. “ (Garris, 2013) Security should not interfere with the daily lives or residents, but should be......

...Case 1 1. What skills does Black think employees need to work successfully in the area of HR? Case1 – The skills that Black thanks employees need to work successfully in HR is for them to be commercial, challenging, and focused on delivery and excellence. They must also understand change and transformation, excel at operations, and balance tactical and strategic thinking and acting. They will have to be able to manage and navigate organizational complexity and ambiguities and not be afraid to say no in order to establish boundaries with the business. I agree with what Black says but I also feel you need to have good communication skills and more importantly, listening skills. You need to take the time to listen to others and see how they are doing and see if they know of any ideas or areas where things can improve. 2. What are some of the outcomes of the company’s new HR strategy? Case1 –The outcomes of the company’s new HR strategy has been great. Early on there were some employees that were unsure about the charges, especially the long-time employees that were used to the old ways. Now everyone sees how it has helped the company and everyone is happy and enjoys working for Lloyds. Another outcome is that the company is being recognized outside the firm. Lloyds was in the Sunday Times top 100 Best Companies to work for in the UK. It was also UK’s top 40 Business Brands by an independent researcher.

...1. Find a list of all 10 of Zappos corporate values. Pick two of the values and explain how you think those values would influence the way employees do their work. A. Zappos list of 10 corporate values are: Deliver WOW Through Service, Embrace and Drive Change, Create Fun and A Little Weirdness, Be Adventurous, Creative, and Open-Minded, Pursue Growth and Learning, Build Open and Honest Relationships with Communication, Build a Positive Team and Family Spirit, Do More with Less, Be Passionate and Determined, and Be Humble. If I had to pick two values from that list they would be Build a Positive Team and Family Spirit and also Build Open and Honest Relationships with Communication. I believe that these two values would have the biggest impact in developing an organizations culture. Organizational culture has been described as the shared values, principles, traditions, and ways of doing things that influence the way organizational members act and that distinguish the organization from other organizations. Organizational culture has many characteristics but the book uses 3 particular words to define culture: Perception, Descriptive, and Shared. An organizations culture cannot be physically touched or seen, the organization is concerned with how members perceive the culture and how the describe it and finally individuals with different backgrounds or work at different levels of the organization can describe the culture of the organization in similar terms. When the key......

Path Unit Case Study #2

...help with a constant dry mouth and to combat her fatigue. At a clinic appointment, it was noted that D.K.’s weight has dropped from 140 to 128 pounds. She is 5 feet 7 inches tall. Her urine specimen shows glycosuria and ketonuria. A chemstick blood glucose level is 412 mg/dl. D.K. had eaten breakfast 3 hours before the chemstick blood test. Discussion Questions 1. Considering D.K.’s presenting history and physical data, what form of diabetes mellitus is indicated? According to D.K.’s history and physical, the type of diabetes mellitus she has is IDDM or more commonly known as insulin dependent diabetes. The symptoms to support the type 1 diabetes are the increased hunger, thirst and urination, rapid weight loss, fatigue and the dry mouth. All of which could be a mechanism for the body compensating for the many symptoms, i.e, the increased thirst and fatigue/weakness is compensated by the onset of the large consumption of coffee. Her body is destroying her cells that produce insulin, which is disabling the body’s ability to absorb insulin to produce energy, hence her symptoms of fatigue and weakness. 2. What are the physiologic mechanisms involved with the polydipsia, polyuria, and polyphagia in diabetes mellitus?  The entire physiologic aspect from diabetes is that when insulin stops being produced in the body the blood glucose begins to raise. The body compensates by filtering out the glucose through the excretion of urine, thus this is why she is having......

Chapter 1 Case 1 and 2 Case Study

...[pic] Robert Half International, Inc. 22 WAYS TO STRIKE OUT WHEN INTERVIEWING A recent survey was conducted among 150 companies to discover why a candidate who is capable of handling a job is not hired. The responses all relate to the crucial interview period. Twenty-two inevitable ways to “strike out” are listed below. If you really want the job, be careful to avoid them all. 1. POOR PERSONAL APPEARANCE A company will be more likely to hire someone who is well groomed and will represent their company in a professional manner. 2. LACK OF INTEREST AND ENTHUSIASM A passive and indifferent attitude is instantly recognized as “I don’t care if I get this job.” Sincere interest and enthusiasm about the position is essential. 3. TOO MUCH EMPHASIS ON MONEY Your interviewing goal is to sell yourself to the interviewer and get an offer of employment. Salary discussion is secondary. 4. CONDEMNATION OF PAST EMPLOYERS Present facts only surrounding the past positions. Interviewers will be sensitive to comments about past employers. Too much information may come across as gossip. 5. TALKING TOO MUCH Answer questions as asked without being abrupt; expound only to the point that the interviewer has a clear understanding of what you mean. Unnecessary conversation wastes time. 6. WEAK HANDSHAKE The interviewer’s first impressions are lasting impressions. A firm handshake shows confidence in yourself and you abilities. 7. REFUSAL TO TRAVEL......

Unit 2 Case Study 1: the Cellular Level of Organization

...Unit 2 Case Study 1: The cellular level of Organization 9/27/2014 A&P1 Answers to “Joseph’s Story” Question B. When the heart is not pumping the oxygen and blood glucose can’t reach the major organs that need the heart to work for them to be sustainable, the cells would not be able to produce ATP after it uses all the energy left in the cell from rapidly burning it up when the oxygen level drops and this function gives power to the cell. The cells will stop functioning and eventually die because of the loss of power in the cellular life and the ATP shuts down the plasma membrane. The cells will began to leak, and sodium will start to leak into the call and potassium will leak out. Question C. All intracellular organelles have membranes as a part of their structure. The breakdown of the membranes of these structures affect the function of the heart because the special calcium ATP had stopped moving calcium from the cytosol into the endoplasmic reticulum of his cardiac muscle cells. As the intracellular calcium levels rose, they caused proteases to spill into the interior of the cell, attacking the cytoskeleton. Lysosome enzymes normally bound safely inside vesicles begin to digest the plasma membranes of the organelles. Question D. His predisposition for vascular disease is held in the Mitochondrial DNA. The information that is needed to repair itself is held in the DNA also but is mainly held in the Messenger RNA. Question E. The integral membrane proteins,...

Week 2 Case Study 1

...Week 2 – Cast Study 1 Robert Dickens Dr. Romy Lu 0001VA016-1138-001 – Advanced Computer Architecture 20 October 2013 Digipos is a company that provides infrastructure solutions specifically tailored to retail oriented companies. Digipos provides a wide range of hardware platforms that include displays, mobile ecommerce solutions, systems, software, and even third party integration solutions. Digipos traditionally recommend that their clients perform a hardware upgrade every five to seven years. This hardware upgrade usually required a complete hardware change which would require a system outage as the old systems are pulled out and the new systems are put in place. This is definitely quite a task to accomplish that can introduce several critical problems. Typically, a hardware replacement requires a “burn-in” period to ensure that the hardware electronics are all stable and not going to fail. Typically this is done before the product is shipped to the client but isn’t always followed and may have to be done on site which would require a risky period of time where their equipment could very possibly fail. Another point of concern is the software and processes that run on the system might have a conflict with the new hardware, but again, this should be fully tested in a lab environment at DigiPos rather than on site at the client’s location. DigiPos decided that these outages were impacting their......

Unit 1 Case Study 1

...AP 2630 Unit 1 Case Study 1 1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection of hematocrit? Lower than normal hematocrit is a sign of anemia. A bacterial infection would increase the production of white blood cells to fight off the infection. The hematocrit would have a thicker buffer layer (white blood cells) causing the red blood cell production to slightly decrease which would decrease the ratio of red blood cells to whole blood volume. 2. Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes and the other formed elements are developed from pluripotent stem cells. The B cell lymphocytes begin and finished in the red bone marrow and the T cell lymphocytes begin in the red bone marrow, but they mature in the thymus. 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the specific production of red blood cells or erythrocytes. Erythropoiesis is speed up when oxygen delivery to the kidneys falls and slows down when there is sufficient oxygen carrying capacity of the blood. 4. Explain what would happen if a person with type B blood were given a transfusion of type O blood. Type O blood is known as the universal donor because any other blood type can safely receive a transfusion, with no negative effects from this type. Therefore, the person receiving the transfusion will be ok. 5. During an anatomy and physiology exam......
