Response to discussion

How would you respond to a discussion like this:

 

 

Carefully define the terms ‘science’ and ‘pseudoscience’. Thoroughly explain the difference between them and provide your references.

Science is defined as a body of knowledge consisting of measurable or verifiable facts that are acquired through application of the scientific method and generalized into scientific laws or principles.  Science is a means for uncovering truth that investigates casual explanations to discover empirical facts about how the world works.  Pseudo-science is defined as a collection of beliefs or practices mistakenly regarded as being based on scientific method.   Pseudo scientific explanations are often overly complex, raises more questions, and doesn’t fit in with what we already know about how the world works.

Also, give at least one example of what counts as science, and of what counts as pseudoscience. Explain how you can tell the difference.

An example of science is the metamorphosis of a caterpillar to a butterfly.  During my childhood, I would visit my grand mother in N.C. She lived in an area surrounded by nature’s beauty, and butterflies were rampant at her house.  It was there that I first witnessed the transformation of a caterpillar into a butterfly.  I was young, and had no preconceived ideas about what was supposed to transpire, so I was completely fascinated about the wondrous process of this event.  I didn’t consider the science behind this. nor did I ask pertinent questions to verify my claims.  I was just a witness to a beautiful creation, which happened to be science.  An example of pseudo-science is homeopathy.  This is a system of treating a sick person by giving extremely small amounts of natural substances that, if given in larger amounts to healthy people would produce the same effects as the disease.  In this case, the difference between science and pseudo- science is the fact that it has been proven and shown beyond any doubt how a caterpillar becomes a butterfly.  With the case of homeopathy, it claims to work, however, when you ask the necessary questions about the claim, for instance, does it fit with the way the world works,  has the claim been verified with someone else, or has anyone tried to disprove the claim, it falls into a pseudo-science category.

Are there any pseudo-scientific claims that you hold? If yes, why is it? 

I actually believe there’s something to the Bermuda Triangle, which is also known as the Devil’s Triangle.   This is an area of many unexplained events like airplanes and ships disappearing under mysterious circumstances.   Because of so many weird occurrences, I would never consider going near that area.

Determine at least two (2) ways in which the material discussed this week has changed your own thinking.

One subject that has sort of changed my thinking is the video discussing the effects of a full moon.  I work in the health care field and whenever there’s a full moon, we brace ourselves for a hectic night.  Before watching the video, I really thought there was some scientific correlation between the full moon and how it effects certain people.  Another take away from this discussion were the pseudo-science theories, other than the Bermuda Triangle, I considered scientific, like Astrology, and Herbalism, or Reflexology, which I totally believe in.

Introduction to Management Science

11) Management science modeling techniques provide results that are known with certainty.

12) The term “sensitivity analysis” refers to testing how a problem solution reacts to changes in one or more of the model parameters.

13) Fixed costs depend on the number of items produced.

14) Variable costs depend on the number of items produced.

15) Fixed cost is the difference between total cost and total variable cost.

16) The break-even point is the volume that equates total revenue with total cost.

17) In general, an increase in price increases the break-even point if all costs are held constant.

18) If variable costs increase, but price and fixed costs are held constant, the break-even point will decrease.

19) Managers utilize spreadsheets to conduct their own analyses in management science studies.

20) Management science techniques focus primarily on observation, model construction, and implementation to find an appropriate solution to a problem.

21) Management science modeling techniques focus on model construction and problem solution.

22) A typical objective function might be written as 3S + 2R + 5Z ≤ 20.

23) Decision Support Systems (DSS) use computers to help decision makers address complex problems.

24) In both an objective function and a constraint, the decision variables are represented by numbers.

25) Constraints usually appear as equations that are less than, equal to, or greater than a parameter.

26) Enterprise Resource Planning (ERP) system is a data-oriented decision support system that utilizes specific management science solution procedures to solve individual problems such as cost-volume analysis.

27) A key element of a decision support system (DSS) is the person using the system.

28) Electronic data interchange (EDI) is a type of decision support system.

29) A ________ is a symbol used to represent an item that can take on any value.

30) ________ are known, constant values that are coefficients of variables in equations.

31) ________ are pieces of information from the problem environment.

32) A ________ is a functional relationship including variables, parameters, and equations.

33) Management science techniques include ________ techniques, models that are represented as diagrams, presenting a pictorial representation of the system being analyzed.

34) An increase in output typically results in an increase in the ________ cost.

35) ________ techniques provide results that contain uncertainty, unlike mathematical programming techniques which are deterministic.

36) ________ costs are independent of the volume of goods produced and remain constant.

38) ________ depend on the number of items produced.

37) The difference between volume multiplied by price and the sum of fixed and variable costs is ________.

 

39) Total revenue minus total cost equals ________.

40) The ________ is the volume that equates total revenue with total cost.

Some dental offices may not employ real dentists and may be front companies that are sending claims out for work not performed. A real dental office should have a real office address with dental chairs, reception areas, etc. Are any dental offices instead

      1.            1-Some dental offices may not employ real dentists and may be front companies that are sending claims out for work not performed. A real dental office should have a real office address with dental chairs, reception areas, etc. Are any dental offices instead using post office boxes in their payment addresses?

      2.           2- Real dentists should be sending claims to many different insurance companies. Since your company only represents a few of these companies, the sequential numbers on the claim sheets from a given dentist will rotate through all the companies that dentist is working with. If the numbers sent to you from a given dentist are sequential, you know that the dentist is only sending claims to you. Search the claims file for sequential numbers from any given dental office. Are any sending you sequential claims?

      3.            3-A human adult has 32 permanent teeth. Your company requires that each claim list the patient seen (identified by “patient id”), the tooth worked on, and the type of work done. Because of the natural limitation on the amount of cavities that could be filled on any one person, it is rare that a person would have more than a few cavities in the three months of your audit (it is possible for a tooth to have more than one cavity). Using this field, calculate the total number of cavities submitted for each patient. Do any patients seem to be visiting the dentist too often?

 

      4.           4- Patients normally need to live close to their dentists because receiving service requires a visit to the office. A good fraud search is to calculate the distance from each customer’s address to his or her dentist’s office address using a geographic information system like Google Maps or MapQuest. For this question, simply determine if any patients live in different states than their dentists. Do any patients seem to have a long drive to their dentists’ offices?

2. Tony M. is a 46 year-old Native American male with a history of hypertension (140/95), elevated serum cholesterol (240 mg/dl), and hypothyroidism. He takes a potassium-depleting diuretic. He recently bought an exercise bike for indoor use and has started a walking program. He also plans to avoid all table salt and to begin reading labels when he goes to the grocery store.

a. What concerns do you have about his intake of iodine, since he plans to avoid table salt? In what other foods might he consume iodine?

b. Tony’s usual diet, which is low in fruits and vegetables, could be low in which minerals? What suggestions do you have for increasing the intake of these minerals?

c. Tony drinks very little milk. What would you recommend for including more calcium in his diet?

d. Fluoridated water is not available. Does this concern you?

3. Mrs. Atkinson has recently seen and heard a lot about the amount of salt in foods. She has been surprised by the number of nutrition web sites that recommend that people decrease the amount of salt in their food. If sodium is such a bad thing, Mrs. Atkinson wonders, why do you need to have any at all? How would you explain this to her?

4. Evelina is a vegan. She stopped eating meat and dairy products when she was a teenager. She is now in her late twenties. She wants to start a family but is concerned about whether she can obtain enough calcium in her diet to ensure her baby’s health. She is also concerned that she might be at risk for osteoporosis. How can Evelina consume enough calcium to meet her own and her baby’s needs?

5. Keep a record of all the food you eat (including portions) over a two day period. You MUST use the 13th edition of Whitney and Rolfes to answer this question. Please note, credit will not be given if your food record is not realistic for two days – recording only a few foods is not realistic. Please do your own work! Answer the following:

a. Using Appendix H of your text, determine how much iron you took in. Show your work to include DA+ code numbers. If your menu item is not listed in Appendix H, use the entry closest to what you ate.

b. Using the DRI table (page B) what is your daily requirement for iron and have you met it? Why or why not?

c. What food groups are considered to be good sources of iron in the American diet?

d. Since iron’s relationship with health is well established, do you take any type of iron supplement in order to meet your dietary needs? If so, what type of iron do you take?

6. Apryl has been diagnosed with iron-deficiency anemia. Her friend Bruce, who is taking a nutrition class, suggested that she take extra vitamin C every day. Apryl is confused by this advice, since her doctor told her to increase the amount of iron in her diet, not the amount of vitamin C. How can Bruce explain his recommendation to her?

7. As Highlight 13 points out, while food was once just food, today food can be and is used as medicine. Discuss some pros and cons of that philosophy.

Cost Club Human Resources Department( answer attached)

Scenario Two: Cost Club and Week Three and Four reading assignments Evaluate the facts presented in the scenario, located on the student website, by applying the relevant legal principles from the reading assignments for Weeks Three and Four. Be sure to meet the requirements as stated in Scenario Two, particularly in the Confidential Update. Write the memo to your boss in 1,050 to 1,400 words that meets the requirements as stated in Scenario Two. Scenario Two: Cost Club Human Resources Department Background This is a continuation of the facts presented in Scenario One. If necessary, review Scenario One before reading Scenario Two. In Scenario One, you assumed the role of Assistant Manager of Human Resources (HR) for a regional office of Cost Club. Your first assignment was to address important issues presented in five messages that your boss, the HR Manager Pat (Pat’s last name is the same as your course facilitator) forwarded to you. Now that you have dealt with those five messages, you are given a broader assignment with more responsibility. Downsizing the Human Resources Department Your boss, Pat, sends you this e-mail: Confidential Update “We currently have eight employees in the HR department, not counting you as assistant manager, and me as department manager. Because of factors beyond our control, we must downsize the department from eight employees to five, and there is NO alternative other than terminating the employment of the three selected. Corporate policy dictates that our region is not authorized to offer any early retirement, conversion to another department, or other less-severe ways of dealing with the downsizing. We must simply discharge three employees, so five will have to do the work of eight. I realize this is a challenging task, especially when you’ve only been here a few weeks. Nevertheless, this may be best, because you don’t have any personal relationships and you can be objective and operate in the best interests of the company. Please provide me with a memo that identifies the employees you believe should be discharged. Include an explanation of what principles of employment law are relevant in the case of each of the three employees: State what the employee would have to prove to win a case of discrimination against us and whether you believe an employee would win the case, based on the facts presented below. Also, indicate what actions management should initiate to put ourselves in the best possible position with regard to each employee’s possible claim of discrimination. Our region encompasses several states, so don’t consider any state laws—just the relevant federal law relating to employment and discrimination. Please send me your recommendations about who to discharge in a memo, and provide any legal references that are relevant. In addition, explain how we should incorporate the relevant legal requirements into the process of termination and the dispute resolution process that we might need if employees raise an objection to the discharge. Finally, I’d like your thoughts on what process we should use to respond to any charge of discrimination from the employees who are discharged. We want to effectively deal with such charges, especially in a climate of downsizing. I don’t have a lot of time for this, so in your memo, please don’t exceed four pages—1400 words. Keep in mind that your memo may become part of the official record, so it’s important to write in a very professional, grammatically-correct manner. I’m also concerned that with so many elements for each of the three employees you select, the message could get confusing, so I’d appreciate you using a table or some other display format that enables me to make comparisons easily. As you know, time is money! -Pat You quietly review the personnel and performance assessment records of each of the eight employees, and you learn the following about them: Abigail is a 28-year old white female personnel specialist who on some occasions acted as a manager in the HR department when the manager or assistant was absent for a week or more. Abigail has a B.S. in Business, and seven years of experience in HR work. She has developed average capability in a variety of HR roles, including record keeping, employee discharge and discipline, and development of the company safety plan. She is considered to be an expert in the area of hiring and training. She also represents the company whenever there are claims for unemployment or workers’ compensation benefits. Abigail is a single woman with no family in the city. Brad has the office next to Abigail. Brad has been with the company for 35 years, and has devoted himself to the business. He has no family to distract him from nearly continuous work with the company. Brad’s only significant activity outside work is his hobby, which is investments. He has made achievements with investing, and is now quite wealthy. Brad is competent in safety, matters of discharge and discipline, and is considered expert in records management. He also is the chief representative for the department in unemployment and workers’ compensation hearings, and is judged to be expert at it. A Morgan Freeman look-alike, Brad is well-liked by the others and is something of a father figure in the unit. Like Abigail, he has frequently acted as department manager or assistant manager during a manager’s absence of a week or more. Charles joined the company about 20 years ago, and has focused on building a deep understanding of the hiring market from which the company recruits technical workers. This knowledge has enabled the company to maintain a strategic advantage, and it always seems that the company gets the best workers in the industry. While Charles has been outstanding in this critical area, he hasn’t learned much about other HR activities, but that was acceptable, because Charles performed such an important task for the company. Charles is an openly gay male, and his lifestyle has never fit well with the majority of the workers of the company. Diane is a 30-year old expert records specialist who also handles all the complicated health care issues for employees. She covers all insurance and health care matters, and additionally deals with injury compensation and workers compensation matters for the company. Diane is a single mother of three small children, and while her work is outstanding, she has had some minor attendance problems related to sick children and other matters during her 10 years with the company. Edith handles all training matters for the company; she is currently involved in coordinating the retraining of those employees who are not being laid off. She also has some competence in the areas of discharge, discipline, and hiring. She is an older married woman who does the work for the love of it, because her husband makes enough money to easily support both of them. She’s been with the organization for 25 years. Some time ago, Edith filed a series of sexual harassment claims against a senior management official in the finance area. The case was settled quickly with an apology and some compensation paid, although Edith has quietly worried since then that there might be retaliation for speaking up. Frank is a disabled black male who, since retiring from the military, has been with the company for 15 years. His work experience is broad, having worked in each area of the HR department at one time or another. His disability does not prevent him from doing most tasks, but for about 25% of the tasks he performs, it does take him longer. Greg has been with the Cost Club HR for 5 years, and has demonstrated considerable ability to learn complex areas quickly, although he’s not above average in any one job. While Frank has been involved in tech hiring, Greg has not. Greg’s religion prevents him from doing any work on Saturday or Sunday, so when there is weekend work, Greg will not participate, forcing other employees to have to do the weekend work more frequently. Horatio is a 22-year old Hispanic male who was hired pursuant to a settlement in an EEO case that Horatio filed; he believed he was denied employment with Cost Club, because of his limited effectiveness with the English language. The company decided that, while it did not believe it had violated Horatio’s rights in any way, it would be a good-faith demonstration for the company to hire him. There was widespread dissatisfaction with the decision to hire someone who was suing the company, so the HR department decided to take Horatio into its own operation, where he would not be exposed to the hard feelings of other employees. He was hired six months ago and is just learning health and insurance, but is still only marginally skilled. As you sift through the performance and personnel records, you wonder who will have to go, and what will happen.

Social Change through Legislation

 

            A legislation that might be the most effective in bringing about lasting social change for treatment and prevention of addiction is legislation targeting the criminal aspect of drug overdose. I select this legislation because, I feel as though when targeting the criminals out in the community such as school premises, corners, blocks and parks will prevent  the kids gaining that negative attention by being influenced by drug use activities. However, where I am from, it is a little too late; primarily high schoolers because, there are no parents in their life, or simply being surrounded by drug use. In the state of New Jersey, the governor developed program for kids who are recovering from addictions (NJ Spotlight, 2017). 

Social Change

 

            This social change legislation might support the professional code of ethics for one, because it approaches the problem of drug use being prevented. Not only are there programs provided, but they are also taking this negative impact of these streets and providing more positive perspectives for the kids, and to keep them off the streets.

Potential Implications

 

            Potential outcome for the helping professionals are them meeting their goals of preventing drug abuse less, and having them engage more in recreation activities involving recovery;  while utilizing strategic skills to help cope with the issues faced in life of substance abuse. Changing or impacting someone’s life is the greatest gift in return.
