      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)

/in /by

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.

BUS475 – Integrated Business Topics Strategic Plan Part III Balanced Scorecard

/in /by

Resource: Exhibit 7-1 in Ch. 7 of Strategic Management

 

Develop the strategic objectives for your business in the format of a balanced scorecard.The strategic objectives are measures of attaining your vision and mission. As you develop them consider the vision, mission, and values for your business and the outcomes of your SWOTT analysis. Consider the following four quadrants of the balanced scorecard when developing your strategic objectives:

 

*** Please remember to submit your Balance Scorecard either as part of your paper or as a separate file.

 

·         Shareholder Value or Financial Perspective, includes strategic objectives in areas such as:   

o    Market share

o    Revenues and costs

o    Profitability

o    Competitive position

·         Customer Value Perspective, includes strategic objectives in areas such as:

o    Customer retention or turnover

o    Customer satisfaction

o    Customer value

·         Process or Internal Operations Perspective, includes strategic objectives in areas such as:

o    Measure of process performance

o    Productivity or productivity improvement

o    Operations metrics

·         Learning and Growth (Employee) Perspective, includes strategic objectives in areas such as:

o    Employee satisfaction

o    Employee turnover or retention

o    Level of organizational capability

o    Nature of organizational culture or climate

o    Technological innovation

 

Develop at least three strategic objectives for each of the following four balanced scorecard areas identified above (Financial, Customer, Process, Learning and Growth). Your objectives should be selected, in part, based on an evaluation of a number of potential alternatives to the issues and/or opportunities identified in the SWOTT Analysis paper and table you completed in Week Three.

 

·         For each strategic objective, develop a metric and target using a balanced scorecard format.

(For example, a common strategic objective in the shareholder or Financial Perspective is to increase market share. A metric to actually measure this strategic objective of market share increase could be: “The percentage of increase in market share.” The target is the specific number to be achieved in a particular time period. The target for the metric of “Increase market share” could be “Increase market share by 2% for each of the next 3 years.)

 

Write a 700- to 1,050-word summary that explains your critical thinking on how you derived your objectives from your vision, mission, values, and SWOTT analysis. You should also incorporate the ethical implications of your solutions into your analysis.

 

Format paper consistent with APA guidelines.

science quiz

/in /by
Ecological succession is halted to keep the agroecosystem in an early-successional state.

       The focus is on monoculture (one plant species instead of many).

       Crops are planted in rows and fields.

       Agroecosystems require plowing, which is unlike any natural soil disturbance.

       All of the above are valid ways that agroecosystems differ from natural ecosystems.

 

Question 2.2. Table 11.1 on page 215 of your text, Environmental Science, provides data regarding land, population, and agriculture. Based on the statistics provided in this table, which continent or continents use over 50% of their total land for agriculture? (Points : 1)

       Asia

       Europe

       Australia

       Both a & c

       All of the above (a, b, & c)

 

Question 3.3. Livestock are often raised on rangeland or pasture. What is/are the major difference(s) in rangeland and pasture? (Points : 1)

       Rangeland is not marked by fencing while pasture is surrounded with barbed or electric wire.

       Rangeland provides food for grazing without planting or plowing while pasture is plowed, planted, and harvested to provide forage for animals.

       Pasture does not utilize irrigation while rangeland is irrigated regularly.

       Pasture and rangeland are the same; however, the term pasture is utilized in the U.S. while rangeland is utilized in Europe and other parts of the world.

       All of the above

 

Question 4.4. While naturally occurring, organic fertilizers (fertilizers made of natural products such as manure) have a number of drawbacks to manmade artificial fertilizers, which of the following is a major drawback of organic fertilizers? (Points : 1)

       Organic fertilizers do not provide enough chemical elements to replace those lost during farming

       Organic fertilizers must be used in conjunction with regular irrigation to ensure effectiveness

       Organic fertilizers are toxic to animals which means they can’t be used on pastures

       Organic fertilizers are toxic to humans which means that they can’t be used on food crops

       None of the above

 

Question 5.5. Crops require about 20 separate chemical elements to survive. Liebig’s law of the minimum states that the growth of a plant is affected by just one limiting factor at a time – the nutrient whose availability is the most limited to the needs of a plant. Based on this law, which of the following statements is true? (Points : 1)

       Increasing the limiting nutrient will improve soil production

       Increased plowing will release nutrients and increase crop production

       Irrigation will stimulate carbon turnover and increase crop production

       Fertilization with a mixture including all of the soil micronutrients is necessary to improve crop growth

       None of the above

 

Question 6.6. Pest management strategies that utilize chemicals (pesticides) often lead to environmental damage, such as the contamination of drinking water. Which pest management technique(s) allow(s) farmers to control pests without applying harmful chemicals? (Points : 1)

       Application of broad spectrum inorganic toxins

       Application of artificial organic compounds

       Utilization of integrated pest management

       Use of biological controls

       None of the above

 

Question 7.7. Some people argue that eating lower on the food chain (eating plants instead of meat) is a more environmentally sustainable practice. Which statement or statements below accurately detail(s) the benefit(s) of eating lower on the food chain addressed in the textbook? (Points : 1)

       Eating lower on the food chain ensures that pesticide intake by the consumer is reduced.

       Eating lower on the food chain ensures sustainability of cattle populations.

       Due to organismal energy efficiency, eating lower on the food chain may allow the same area of farmland to produce between 10 and 100 times more vegetation per year than eating meat.

       Both a & b

       All of the above (a, b, & c)

 

Question 8.8. Genetic engineering in agriculture involves a number of different technical practices. Which following practice or practices mentioned in your textbook is/are considered current genetic engineering technologies? (Points : 1)

       Faster and more efficient development of new hybrids

       Introduction of the “terminator” gene

       Transfer of genetic properties from widely divergent kinds of life

       Both a & b

       All of the above (a, b, & c)

 

Question 9.9. The terminator gene makes seeds from a crop sterile. What is/are the reason(s) for inserting a terminator gene into a crop? (Points : 1)

       It prevents farmers from using the next generation of seeds so that they must purchase new seeds each year

       It prevents a genetically modified crop from spreading to nearby farms and natural areas

       It keeps Arnold Schwarzenegger away

       Both a & b

       None of the above

 

Question 10.10. Aquaculture (the farming of fish) provides many benefits to traditional fishing and/or farming practices. However, as with all sources of food production, it also has its drawbacks. Which of the following negative environmental impact or impacts discussed in your book is/are commonly caused by aquaculture? (Points : 1)

       Air pollution

       Damage of biological diversity

       Soil erosion

       Both a & c

       All of the above

Develop an application

/in /by

Develop an application that will determine whether any of several department-store customers has exceeded the credit limit on a charge account. For each customer, the following facts are available:

 a. account number

 b. balance at the beginning of the month

 c. total of all items charged by the customer this month

 d. total of all credits applied to the customer’s account this month

 e. allowed credit limit.

 The program should input all these facts as integers, calculate the new balance (= beginning balance + charges — credits), display the new balance and determine whether the new balance exceeds the customer’s credit limit. For those customers whose credit limit is exceeded, the program should display the message “Credit limit exceeded”. Your class should have a constructor that initializes the instance variables. Account number is auto generated and user is not supposed to enter it. Provide a set and a get method for each instance variable.

 

Develop a C++ program that will determine whether a department-store customer has exceeded the credit limit on a charge account. For each customer, the following facts are available:

 

a) Account number (an integer)

b) Balance at the beginning of the month

c) Total of all items charged by this customer this month

d) Total of all credits applied to this customer’s account this month

e) Allowed credit limit

 

The program should use a while statement to input each of these facts, calculate the new balance (= beginning balance + charges – credits) and determine whether the new balance exceeds the customer’s credit limit. For those customers whose credit limit is exceeded, the program should display the customer’s account number, credit limit, new balance and the message “Credit Limit Exceeded.”
