Researchers recently investigated whether or not coffee prevented the development of high blood sugar (hyperglycemia) in laboratory mice. The mice used in this experiment have a mutation that makes them become diabetic. Read about this research study in this article published on the Science Daily web-site New Evidence That Drinking Coffee May Reduce the Risk of Diabetes as well as the following summary: A group of 11 mice was given water, and another group of 10 mice was supplied with diluted black coffee (coffee:water 1:1) as drinking fluids for five weeks. The composition of the diets and living conditions were similar for both groups of mice. Blood glucose was monitored weekly for all mice. After five weeks, there was no change in average body weight between groups. Results indicated that blood glucose concentrations increased significantly in the mice that drank water compared with those that were supplied with coffee. Finally, blood glucose concentration in the coffee group exhibited a 30 percent decrease compared with that in the water group. In the original paper, the investigators acknowledged that the coffee for the experiment was supplied as a gift from a corporation. Then answer the following questions in your own words: 1. Identify and describe the steps of the scientific method. Which observations do you think the scientists made leading up to this research study? Given your understanding of the experimental design, formulate a specific hypothesis that is being tested in this experiment. Describe the experimental design including control and treatment group(s), and dependent and independent variables. Summarize the results and the conclusion (50 points) 2. Criticize the research described. Things to consider: Were the test subjects and treatments relevant and appropriate? Was the sample size large enough? Were the methods used appropriate? Can you think of a potential bias in a research study like this? What are the limitations of the conclusions made in this research study? Address at least two of these questions in your critique of the research study (20 points). 3. Discuss the relevance of this type of research, both for the world in general and for you personally (20 points). 4. Write answers in your own words with proper grammar and spelling (10 points)

Excel Review Assignment #1 – ISM3011 Ask before/after/during class or come into office/online hours if you have questions on any of this. Refer to the syllabus on Academic Dishonesty and group/individual work and allowable help for all projects – also remember it’s your responsibility to protect your work. Before you start — read this whole assignment and use your optional text and/or review the tutorials as necessary on Canvas or www.bwarner.org/tips. A project overview for each project is also available. Part 1 – Create / Download / Parts • Create a blank workbook. Name it using your Last name followed by your initials and _ 1EX (underscore then 1EX). For Example: WarnerBL_1EX .xlsx. Either extension is fine. • Download the Word file Ex1 Data1-F15.docx and copy/paste Word table from the file into the 2nd worksheet in your workbook. Name the tab ‘2014 Sales’. • Download the Word file Ex1 Data2-F15.docx and copy/paste Word table from the file into the 3rd worksheet in your workbook. Name the tab ‘2015 Sales’. • Adjust the column widths of both Sales worksheets so that no data is cut off. • Do not add any formulas or cells to the Sales worksheets Part 2 – Summary Worksheet • Create a summary sheet from the Sales worksheets. Name the worksheet ‘Summary’. Build two summaries on this worksheet. Summary 1: Comparison of Sales by Month and Summary 2: Comparison of Sales by Store ID. • Use the project overview as a guide for the format. Use colors, borders and backgrounds to make the worksheet look professional. o Include the following:  Month and Store ID headings that reference the 2014 Sales worksheet. This means if ‘January’ is changed to ‘Jan’ in the 2014 Sales worksheet, the summary worksheet heading will also change. Do the same with the Store ID and 2014 Sales worksheet.  Formulas that reference the 2014 and 2015 Sales worksheets. If the Sales worksheets change, the summary worksheet should also adjust automatically.  Correct format for all book totals (commas, no decimal places)  Correct % change formulas in both tables. This is how much the totals have changed compared to the 2014 totals.  Correct format for all % change (% sign, 1 decimal place).  Use borders and background colors on the column & row headings for both tables of data • On the summary worksheet, use conditional formatting to highlight any % change cell that greater than zero with a bright color background. If the % change is negative, display the value with a red font and no background color. o There should be only two conditional formats set on each cell. o **Note – to do the conditional formatting steps, you can set the conditional formatting for one cell and then use the format painter to apply to other appropriate cells. If the values are all changed, the conditional formatting should still work. Once you have it working, check by changing some values & see if the conditional formatting changes correctly. Return to the original values/formulas in the cell before you submit. If you don’t use the format painter for this be sure you still try it out & understand how it works. Part 3 – Chart • Create 2 column graphs displaying Totals by Month and Totals by Store ID. Include: • Titles on both chart as well as labeling on the x and the y axis. • Color fonts for the title and axis labels (not dark blue or black) • Large font for the title (at least 16 point) • Include a legend • Format the background (chart area/walls) of the graph with a texture – use one that is easy to see. • Be sure that if any headings or numbers in the worksheets change, these changes are automatically reflected in your chart. • Add a star or banner shape between the two charts and add your name. Be sure the text is part of the shape (not a shape and a separate text box). Part 4 – Finishing Up • Be sure your worksheet tabs are named correctly and if possible, make each worksheet tab a distinctly different color. If your version of Excel doesn’t allow this, don’t worry about it. But do delete any additional worksheets in the workbook. • Create a title in the first row of your summary worksheet. Use the merge and center feature (across all columns with data) and a larger font & different font color (not blue or black). Also add a background color. Add a comment with your email address and the date your spreadsheet was created. • Below the title, add a row with the current date (use the today or now formula) so it is updated whenever the spreadsheet is opened). • Check your formulas, be sure they are correct and make sense. For example, if you are subtracting 2 numbers don’t use the SUM formulas (sum is for adding). Excel may figure out what you mean, but we want the formulas to be used correctly (show that you understand how to use them). • Check your worksheet for errors! Potential errors in cells show up as small green triangles in the top left corner of each cell. Do a little Googling on error checking for your version of Excel and be sure you have error checking turned on and that you reconcile each error so they don’t display when we open your project for grading. Sample: Project Submission Instructions / Notes: • Office/online hours get busy as deadlines approach. If you procrastinate and wait until the last days to work on your project, you may not be able to get all the help you want. • The only way we can fairly grade the projects is if we check for each requirement. Please go through the instructions before you submit & be sure you have done each one correctly so you don’t miss out on points. Compare your solution to the project overview. • Submitting: o Remember to leave all of the internal file properties intact for your project, if they are modified or deleted, you project won’t be accepted (see syllabus for more on this). o Read and follow the instructions in the Assignments section of Canvas on uploading and checking your upload. If you follow these instructions you can ensure that your project is uploaded correctly (and is the correct project). Be sure that Access / Excel are closed before you try to upload your project files. o If your project doesn’t upload correctly before the due date, it will be considered late and be assessed the late penalty – even it was finished on time. This is the only way we can ensure that students check their Canvas submissions. • Technology problems relating to your home computer (Windows based or Mac), internet connection or slow Canvas access are not valid excuses for late/missing work, unless Canvas is down for 6+ hours on the due date. Computers at USF computer labs and the library are available; leave enough time to access them as needed. Also give yourself enough time that if a TA can’t answer a question, you’ll have time to contact me & I can either help you or make an allowance in your grade. If you wait until the last days, I may not be able to do either.

Sex, Gender, and Popular Culture Spring 2015 Look through popular magazines, and see if you can find advertisements that objectify women in order to sell a product. Alternately, you may use an advertisement on television (but make sure to provide a link to the ad so I can see it!). Study these images then write a paper about objectification that deals with all or some of the following: • What effect(s), if any, do you think the objectification of women’s bodies has on our culture? • Jean Kilbourne states “turning a human being into a thing is almost always the first step toward justifying violence against that person.” What do you think she means by this? Do you agree with her reasoning? Why or why not? • Some people would argue that depicting a woman’s body as an object is a form of art. What is your opinion of this point of view? Explain your reasoning. • Why do you think that women are objectified more often than men are? • How does sexualization and objectification play out differently across racial lines? • Kilbourne explains that the consequences of being objectified are different – and more serious – for women than for men. Do you agree? How is the world different for women than it is for men? How do objectified images of women interact with those in our culture differently from the way images of men do? Why is it important to look at images in the context of the culture? • What is the difference between sexual objectification and sexual subjectification? (Ros Gill ) • How do ads construct violent white masculinity and how does that vision of masculinity hurt both men and women? Throughout your written analysis, be sure to make clear and specific reference to the images you selected, and please submit these images with your paper. Make sure you engage with and reference to at least 4 of the following authors: Kilbourne, Bordo, Hunter & Soto, Rose, Durham, Gill, Katz, Schuchardt, Ono and Buescher. Guidelines:  Keep your content focused on structural, systemic, institutional factors rather than the individual: BE ANALYTICAL NOT ANECDOTAL.  Avoid using the first person or including personal stories/reactions. You must make sure to actively engage with your readings: these essays need to be informed and framed by the theoretical material you have been reading this semester.  Keep within the 4-6 page limit; use 12-point font, double spacing and 1-inch margins.  Use formal writing conventions (introduction/thesis statement, body, conclusion) and correct grammar. Resources may be cited within the text of your paper, i.e. (Walters, 2013).

ANSWER: Correct Free-Body Diagrams Learning Goal: To gain practice drawing free-body diagrams Whenever you face a problem involving forces, always start with a free-body diagram. a1 a1 = 1.67 m s2 a2 a2 = 3.33 m s2 Typesetting math: 100% To draw a free-body diagram use the following steps: Isolate the object of interest. It is customary to represent the object of interest as a point 1. in your diagram. Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that are not forces. 2. Draw the vectors for each force acting on your object of interest. When possible, the length of the force vectors you draw should represent the relative magnitudes of the forces acting on the object. 3. In most problems, after you have drawn the free-body diagrams, you will explicitly label your coordinate axes and directions. Always make the object of interest the origin of your coordinate system. Then you will need to divide the forces into x and y components, sum the x and y forces, and apply Newton's first or second law. In this problem you will only draw the free-body diagram. Suppose that you are asked to solve the following problem: Chadwick is pushing a piano across a level floor (see the figure). The piano can slide across the floor without friction. If Chadwick applies a horizontal force to the piano, what is the piano's acceleration? To solve this problem you should start by drawing a free-body diagram. Part A Determine the object of interest for the situation described in the problem introduction. Hint 1. How to approach the problem You should first think about the question you are trying to answer: What is the acceleration of the piano? The object of interest in this situation will be the object whose acceleration you are asked to find. ANSWER: Typesetting math: 100% Correct Part B Identify the forces acting on the object of interest. From the list below, select the forces that act on the piano. Check all that apply. ANSWER: Correct Now that you have identified the forces acting on the piano, you should draw the free-body diagram. Draw the length of your vectors to represent the relative magnitudes of the forces, but you don't need to worry about the exact scale. You won't have the exact value of all of the forces until you finish solving the problem. To maximize your learning, you should draw the diagram yourself before looking at the choices in the next part. You are on your honor to do so. Part C For this situation you should draw a free-body diagram for the floor. Chadwick. the piano. acceleration of the piano gravitational force acting on the piano (piano's weight) speed of the piano gravitational force acting on Chadwick (Chadwick's weight) force of the floor on the piano (normal force) force of the piano on the floor force of Chadwick on the piano force of the piano pushing on Chadwick Typesetting math: 100% Select the choice that best matches the free-body diagram you have drawn for the piano. Hint 1. Determine the directions and relative magnitudes of the forces Which of the following statements best describes the correct directions and relative magnitudes of the forces involved? ANSWER: ANSWER: The normal force and weight are both upward and the pushing force is horizontal. The normal force and weight are both downward and the pushing force is horizontal. The normal force is upward, the weight is downward, and the pushing force is horizontal. The normal force has a greater magnitude than the weight. The normal force is upward, the weight is downward, and the pushing force is horizontal. The normal force and weight have the same magnitude. The normal force is upward, the weight is downward, and the pushing force is horizontal. The normal force has a smaller magnitude than the weight. Typesetting math: 100% Typesetting math: 100% Correct If you were actually going to solve this problem rather than just draw the free-body diagram, you would need to define the coordinate system. Choose the position of the piano as the origin. In this case it is simplest to let the y axis point vertically upward and the x axis point horizontally to the right, in the direction of the acceleration. Chadwick now needs to push the piano up a ramp and into a moving van. at left. The ramp is frictionless. Is Chadwick strong enough to push the piano up the ramp alone or must he get help? To solve this problem you should start by drawing a free-body diagram. Part D Determine the object of interest for this situation. ANSWER: Correct Now draw the free-body diagram of the piano in this new situation. Follow the same sequence of steps that you followed for the first situation. Again draw your diagram before you look at the choices For this situation, you should draw a free-body diagram for the ramp. Chadwick. the piano. Typesetting math: 100% below.

Select Case 1, 2, or 8 in the back of the textbook. After you have read the case, select at least one of the questions presented at the end.-If you select only one question, then you will need to elaborate with more examples and perspectives than if you select more than one, but the choice is yours. Fair warning: It is possible to fall into the trap of repeating oneself. To avoid that threat, think in advance of the different perspectives that you wish to explore. If you select more than one question, each answer will naturally be shorter. This may be a good approach if you discern that the questions lack strong potential to elicit in-depth answers. Remember to reply to the contributions of two other students in this exercise. This is a rule that we are only observing in the case analyses, given the relative complexity of the cases, compared to the chapter discussion questions. Always add value, from the textbook, news, personal experience, or all three. Indicate the case and question at the beginning, but avoid restating the question in your answer. In this respect, use the same method as in the chapter discussion questions, described in the Week 2 forum. Write at least 500 words (no minimum for replies, but do add value). Quoted passages do not contribute to the word count (so you will need to write more if you insert any quoted material). Post-edit your work carefully to catch errors. Avoid plagiarism at all cost. ——— Note on anomalous questions. Some questions will require you to work around selected details to fit the requisite discussion format. For example, Question 2 in Case 1 asks how your proposal will solve certain problems noted in answer to the previous question. If you have not actually answered Question 1, then you will have to assert one or more problems from the case, a proposed solution, and then an explanation of how your proposal may help. Question 3 is similar, in that you will need to identify a problem and a solution, followed by an argument about the budget. Although Alistair was expecting to hire a Project Engineer rather than a Quality Compliance Manager, the methods used to make the decision should be similar. The main difference in the Quality Compliance Manager position is that it is in a joint venture with a Hungarian government backed firm. International Joint Ventures (IJV) makes HRM practices more complicated because HRM practices and strategies are required for each IJV entity (Dowling, Festing, & Engle, 2013). HRM must address IJV in four stages, in which, each stage has an impact on the next. It is important for HRM to very thorough with each stage and communication through each stage is vital. To be successful, HRM must combine the IJV strategy along with the recruitment, selection, training, and development processes (Dowling et al., 2013). In light of the needs of the company and the new Quality Compliance Manager position, Alistair should choose the first candidate, Marie Erten-Loiseau. The fact that the job requires travel to France and Germany is a positive for Marie because she was born in France and was educated in France and Germany. The familiarity of these locations will help her as she meets with new business partners because she will have a good understanding of the policy and procedures required for companies in these two countries. Dowling et al., (2013), points out that the manager needs to be able to assess the desires of the stakeholders and be able to implement strategies based on their desires. Another reason for choosing Marie is that she has the most experience and has worked with Trianon for 13 years. The experience she has with the company is invaluable because she knows the goals of the company and strategies for implementing those goals. The last reason for choosing Marie is that she has been successful in her previous positions. She has lead two projects in two different countries and both were successful. This shows that she is able to adapt to the different practices of each country. There are many factors that Alistair should take into consideration to determine the correct choice for the Quality Compliance Manager position. The major factors that require consideration are the specificities of the entire situation, the reason for the assignment, and type of assignment. The four main specificities include context specificities, firm specific variables, local unit specificities, and IHRM practices (Dowling et al., 2013). The context specificities would include the differences in cultures between the assignment in Hungary and the base location for the Trianon, Marseilles. The firm specific variable includes any changes in the way operations in Hungary are conducted, whether it is strategy or HRM policies. The local unit specificities include the role of the joint venture in relation to Trianon and how this joint venture will fit into the long-term plan of the company. The company hopes that it will provide a good working relationship with the state supported airline, which will lead to more business in the future. The IHRM practices determine the employees that are hired and the training that is available to the employees. The reason for the assignment also is a major factor in determining the correct candidate. In the situation of Trianon, a joint venture with a Hungarian government back firm created a position that needed filling. The Quality Compliance Manager position allows Trianon to manage the joint venture operation, make sure it is successful, and build a strong relationship with Malev. The last major factor is the type of assignment. The Quality Compliance Manager assignment is long-term assignment because it is 3 years in duration. The joint venture is the first that the company has been involved in outside the UK so there is less familiarity on the administrative/compliance side. The candidate must act as an agent of direct control (Dowling et al., 2013) by assuring that compliance policies are followed and company strategy is implemented. Assessing whether a male or female would be the best fit for the position is also a factor that deserves consideration. The low number of female expatriates led Jessens, Cappellen, &Zanoni (2006) to research the following three myths: women have no desire to be in positions of authority in a foreign country, companies do not desire to place females in positions of authority while a foreign country, and women would be ineffective because of the views towards women in foreign countries. The research indicated that female expatriates do have conflict that arises related to their gender but the successful ones were able to turn the conflicts around based on the qualities that these women possess (Jessens et al., 2006). With all of these factors considered, I believe Marie Erten-Loiseau is the best candidate for the Quality Compliance Manager. References Dowling, P.J., Festing, M., & Engle, A.D. Sr. (2013).

Case 8 – Questions 1 & 4 Multinational firms are often faced with recruiting and staffing decisions that could ultimately enhance or diminish the firm’s ability to be successful in a competitive global market. Perlmutter identified four staffing approaches for MNEs to consider based on the primary attitudes of international executives that would lay the foundation for MNEs during the recruitment and hiring process (Dowling, Festing, & Engle, 2013). At one point or another throughout the MacDougall family journey Lachlan and Lisa have served in one of the four capacities as an ethnocentric, polycentric, geocentric, and regiocentric employee. The ability to encompass all four attitudes that Perlmutter set forth is something that the MacDougall family has managed to do extremely well. The possibility for a multinational firm to recruit a family of this caliber that has been exposed and has an understanding of the positive and negative aspects of each attitude is phenomenal. This would be resourceful for any multinational firm. The MacDougal family’s exposure to cross-cultural management is also valuable. The diverse cultural background that the family has encountered on their international journey is a rarity. Cultural diversity and cross-cultural management play a critical role in MNEs because it produces a work environment that can transform the workplace into a place of learning and give the firm the availability to create new ideas for a more productive and competitive advantage over other firms (Sultana, Rashid, Mohiuddin, &Mazumder, 2013). This is something that is easy for the MacDougall family to bring to the table with the family’s given history. The expatriate lifestyle that has become second nature to the MacDougall family is beneficial for multinational firms for multifarious reasons Being raised around different cultures and then choosing to work internationally and learn different cultures has attributed to Lachlan’s successful career. The family’s ability to communicate and blend in socially among diverse cultures is an important aspect for international firms that want to stay competitive and be successful. The family has acclimated fairly easy to all of the places they have been and this is something that can be favorable when firms are recruiting employees. The MacDougall family has an upper-hand in the international marketplace naturally due to previous experiences with other countries and cultures. The exceptional way that the family has managed to conform to a multitude of other cultures and flourish is not an easy task. Marriage is not easy and many families experience a greater challenge avoiding divorcees when international mobility is involved. Lachlan and Lisa have been able to move together and this is an important aspect to the success of their marriage. Based on the case study they have a common desire to travel and both are successful in their careers. Lisa’s devotion to her husband’s successful career has put some strain on the marriage as she has had times where she felt she did not have her own identity. Military spouses experience this type of stress during long deployments and times that they have to hold the household together on their own. Another example is with employers who are transferred internationally for a short period of time or travel often. Separation of spouses can strain any marriage, but Lisa and Lachlan have been fortunate to avoid separation for any extended length of time.

Select Case 1, 2, or 8 in the back of the textbook. After you have read the case, select at least one of the questions presented at the end.-If you select only one question, then you will need to elaborate with more examples and perspectives than if you select more than one, but the choice is yours. Fair warning: It is possible to fall into the trap of repeating oneself. To avoid that threat, think in advance of the different perspectives that you wish to explore. If you select more than one question, each answer will naturally be shorter. This may be a good approach if you discern that the questions lack strong potential to elicit in-depth answers. Remember to reply to the contributions of two other students in this exercise. This is a rule that we are only observing in the case analyses, given the relative complexity of the cases, compared to the chapter discussion questions. Always add value, from the textbook, news, personal experience, or all three. Indicate the case and question at the beginning, but avoid restating the question in your answer. In this respect, use the same method as in the chapter discussion questions, described in the Week 2 forum. Write at least 500 words (no minimum for replies, but do add value). Quoted passages do not contribute to the word count (so you will need to write more if you insert any quoted material). Post-edit your work carefully to catch errors. Avoid plagiarism at all cost. ——— Note on anomalous questions. Some questions will require you to work around selected details to fit the requisite discussion format. For example, Question 2 in Case 1 asks how your proposal will solve certain problems noted in answer to the previous question. If you have not actually answered Question 1, then you will have to assert one or more problems from the case, a proposed solution, and then an explanation of how your proposal may help. Question 3 is similar, in that you will need to identify a problem and a solution, followed by an argument about the budget. Although Alistair was expecting to hire a Project Engineer rather than a Quality Compliance Manager, the methods used to make the decision should be similar. The main difference in the Quality Compliance Manager position is that it is in a joint venture with a Hungarian government backed firm. International Joint Ventures (IJV) makes HRM practices more complicated because HRM practices and strategies are required for each IJV entity (Dowling, Festing, & Engle, 2013). HRM must address IJV in four stages, in which, each stage has an impact on the next. It is important for HRM to very thorough with each stage and communication through each stage is vital. To be successful, HRM must combine the IJV strategy along with the recruitment, selection, training, and development processes (Dowling et al., 2013). In light of the needs of the company and the new Quality Compliance Manager position, Alistair should choose the first candidate, Marie Erten-Loiseau. The fact that the job requires travel to France and Germany is a positive for Marie because she was born in France and was educated in France and Germany. The familiarity of these locations will help her as she meets with new business partners because she will have a good understanding of the policy and procedures required for companies in these two countries. Dowling et al., (2013), points out that the manager needs to be able to assess the desires of the stakeholders and be able to implement strategies based on their desires. Another reason for choosing Marie is that she has the most experience and has worked with Trianon for 13 years. The experience she has with the company is invaluable because she knows the goals of the company and strategies for implementing those goals. The last reason for choosing Marie is that she has been successful in her previous positions. She has lead two projects in two different countries and both were successful. This shows that she is able to adapt to the different practices of each country. There are many factors that Alistair should take into consideration to determine the correct choice for the Quality Compliance Manager position. The major factors that require consideration are the specificities of the entire situation, the reason for the assignment, and type of assignment. The four main specificities include context specificities, firm specific variables, local unit specificities, and IHRM practices (Dowling et al., 2013). The context specificities would include the differences in cultures between the assignment in Hungary and the base location for the Trianon, Marseilles. The firm specific variable includes any changes in the way operations in Hungary are conducted, whether it is strategy or HRM policies. The local unit specificities include the role of the joint venture in relation to Trianon and how this joint venture will fit into the long-term plan of the company. The company hopes that it will provide a good working relationship with the state supported airline, which will lead to more business in the future. The IHRM practices determine the employees that are hired and the training that is available to the employees. The reason for the assignment also is a major factor in determining the correct candidate. In the situation of Trianon, a joint venture with a Hungarian government back firm created a position that needed filling. The Quality Compliance Manager position allows Trianon to manage the joint venture operation, make sure it is successful, and build a strong relationship with Malev. The last major factor is the type of assignment. The Quality Compliance Manager assignment is long-term assignment because it is 3 years in duration. The joint venture is the first that the company has been involved in outside the UK so there is less familiarity on the administrative/compliance side. The candidate must act as an agent of direct control (Dowling et al., 2013) by assuring that compliance policies are followed and company strategy is implemented. Assessing whether a male or female would be the best fit for the position is also a factor that deserves consideration. The low number of female expatriates led Jessens, Cappellen, &Zanoni (2006) to research the following three myths: women have no desire to be in positions of authority in a foreign country, companies do not desire to place females in positions of authority while a foreign country, and women would be ineffective because of the views towards women in foreign countries.
