Water fluoridation is an important preventative measure carried out in much of the western world. It results in some of the hydroxyapatite, Ca₅(PO₄)₃OH, of which human tooth enamel is made being replaced by fluoroapatite, Ca₅(PO₄)₃F - a substance significantly more resistant to decay. Thus, to protect the teeth of the population, water is often fluoridated. This is usually done with one of three fluorine-containing chemicals (sodium fluoride, sodium fluorosilicate and hydrofluorosilicic acid). The following equations describe the reactions that occur on human tooth with and without fluoridation.

Tooth decay: Ca₅(PO₄)₃OH_(s) + 4H₃O⁺ → 5Ca²⁺ + 3HPO₄^2- + 5H₂O

Fluoridation: 6Ca₅(PO₄)₃OH_(s) + H₂SiF₆ → 6Ca₅(PO₄)₃F_(s) + SiO₂ + 4H₂O

a)Calculate the percent fluoride by weight in H₂SiF₆.

b)Minnesota Statutes require all municipal water supplies to maintain a fluoride concentration of 0.9 ppm to 1.5 ppm (measured as mass of F per liter), with an optimum level of 1.2 ppm (measured as mass of F per liter). The city of Mankato, MN uses groundwater wells for water supply. The flow of one of the wells is 1,000 gallons per minute (gpm) and runs for 24 hours. The city aims to achieve optimum concentrations of fluoride. The city uses hydrofluorosilicic acid (H₂SiF₆) with 25 % purity. How many gallons of acid per day must the city add for each well to keep the concentration to 1.2 ppm?

c)According to the fluoridation reaction given above, how much fluoroapatite, Ca₅(PO₄)₃F, is produced when the concentration of hydrofluorosilicic acid,H₂SiF₆, is supplied at 1.2 ppm?

XYZ Hospital does not allocate Support Costs by Dept to Patient Service Depts, and has historically done P&L statement.

Part 1: Use Step Down cost allocation method to allocate Support Dept Costs to Patient Service Depts in order to know profitability of each Patient Service Dept. Allocate costs in this order and by 3 following methods:

1) Housekeeping by Square Feet
2) Human Resources: by Number of Employees
3) General Administration: By Revenue

Complete a dept cost allocation schedule identifying all relevant allocation rates, amounts allocated, cost pools, drivers, etc. and a final Profit and Loss calculation by Patient Service Dept for each of the 3 methods.

Ex:

Part 2: Apply housekeeping labor hours rather than square feet to allocate housekeeping costs for each of the three methods.

You are a supervisor in Macklin Corporation, a manufacturer of carpentry tools, that is located in Los Angeles. During a recent staff meeting, employee motivation was a major topic of discussion. A number of the supervisors indicated that their subordinates don’t seem to be as highly motivated as they were a few years ago. As a result, work is not produced as quickly or with as much quality as was the case earlier. Some at the meeting indicated that is a sign of the time—that is not the fault of Macklin. Others indicated that they believed the problem stemmed from the fact that salary increases have been lower the last several years than ever before, primarily because the company is not as profitable as it was earlier. Others said that they believed the problem of employee motivation can be attributed to a lack of fringe benefits in Macklin, especially since an increasing number of companies in the Los Angeles area are being more generous with the benefits they offer. To Create the problem, several supervisors recommend that a consultant be brought in. another recommendation was to have the personnel department do an in-house study to determine the source of the problem. A questionnaire could be developed that employees would respond to anonymously. While no decisions were made at the meeting. The executive vice president who was conducting the meeting asked for the input regarding your ideas about (1) the reasons why the employees are not as highly motivated as they were in the past and (2) whether the study should be conducted by a consultant or by the human resources department. 1. Do you believe that small salary increases and a lack of fringe benefits may be the cause of the motivation problem? Why? 2. What other possible explanations for the motivation problem might exist? 3. Do you believe that a consultant should be hired, or do you believe the human resources department should conduct the study? Why?

SuperDry Manufactures and sells T-shirts for all kinds of events. The company has two manufacturing operations- shirt-making and printing. When the company receives an order, the shirt-making department obtains the materials requested and has the fabric cut and sewn to sizes. The ready T-shirts are then sent to the printing department where the customer labels or design are prepared and printed onto the surface with hot press machines.

SuperDry has three support departments- Building Maintenance, Human Resources and Design & patterns. For the 1^st quarter of 201X, the direct/direct overhead costs incurred by each department are as follows (direct costs for S1- S3; direct overhead costs for P1, P2, and R):

Shirt-making (P1)                             $260,000              Building maintenance (S1)           $65,000

Printing (P2)                                       $170,000              Human Resources (S2)                  $40.000

Sales (R)                                               $84,000 Design & Patterns (S3)                   $38,000

The cost drivers identified for costs incurred by S1, S2 and S3 are numbers of square footage,

Number of employees and the number of designs respectively.

The following table summarises the usage of the costs driver by each department:

                                                                S1           S2           S3           P1           P2           R

Number of Design -              -              -              16           30           8

Number of Employees 4              2              6              20           12           12

Square feet                                        5,000 10000 10000 15000 25000 5000

Required:

i)SupeDry allocates support department costs using the step-down method. Recommend the order by which SuperDry should do so. Justify your recommendation.

ii)Compute the total amount of overhead costs for P1, P2 and R using the step-down method and based on the order recommended in part (1).

The largest cat in North America is the Jaguar. They can sometimes be seen in the mountains of Southern Texas, Arizona, and New Mexico, (and less recently southern California). The rate of observances by humans is about 4/20 years. Assume we don't get Trump’s border wall which would isolate the US population from the rest, and presumably cut off their chance of commuting and breeding.

a. You set up a network of automated infrared cameras from the southern border to 100 miles north of the border all along the Texas, Arizona, and New Mexico border. If the rate of appearance of Jaguars this side of the Mexican border is 4/20 year what are the chances you see 5 or more separate Jaguars within 5 years? (Assume Poisson)

b. Your cameras also produce pictures of wolf sized canids, either wolves or coy-wolves in the same region (very different times). Each year your cameras catch about 30 of these animals and about 40 cougars and about 500 bear and 1000 feral hogs. Assume that these numbers are all population rates for Poisson. Given your camera network catches a non human large animal (and the above list is all of them):

i)What is the probability it is a jaguar?

ii)What is the probability it is a feral hog?

iii)Out of 10 large nonhuman animals, what is the probability that 7 or more are feral hogs (Hint N=10, P is fixed, independent trials)

iv)Out of 100 large non human animals what is the probability that between 40 and 70 are feral hogs? (Use an approximation)

Objective: To provide you with an opportunity to determine and access resources and systems to manage financial management processes within the work team>

CaseStudy: Outline the following resources and systems, as they pertain to your organisation:

• Hardware and software

Many organizations use some type of computerisation, keeping their financial records digitally using computers.

Software can include:

• A universal ledger
• End to end spend management program
• Budgeting, planning and forecasting program
• Reporting program
• Process and control automation program
• Human, physical or financial resources

Human resources

Skillsets that an organization has within its staff such as staff experience, qualifications, training standards and other factors like morale, business culture and work relationships.

Physical resources

• production facilities
• marketing facilities
• Information Technology
• Record keeping systems (electronic and paper-based)

Paper-based record keeping

Keeping records manually – especially in cash accounting approach—

Divided in to some sections; Receipts, Payments, Wages and superannuation, Bank reconciliation, Inventory.

Electronic record keeping

Keeping records in electronic portals. It is the most efficient way to keep financial records and accounts. Computer-based accounting programs can create many things an organization needs such as:

• Orders
• Invoices
• Aged debtor reports
• Financial statements
• Specialist advice or support.

Asking for an advice or support from other stakeholders like accountants, bookkeepers and mentors

Question:

Why are they needed? How do you access them? Is there any current discussion within your organisation to change any of these resources? What impact will that have?

how to debate this representation to protect the idea: I agree that emotional intelligence is reliable in predicting important behaviour and improving job performance.

"Now we as today's opposition strongly believe that emotional intelligence is not a reliable index. In today’s society, the working environment is becoming more complex based on business journals (2020) the author has classified factors affecting business environment into 3 main sections including macro-environment such as political factors, economy or technology, and external environment such as competitors, customers, suppliers and last but not least internal environment such as human resources, management, marketing, and so on are all factors that influence the employee's working attitude and emotions. Therefore, we can conclude that in order to adapt to a complex and volatile environment, employees must change their work attitudes every second. After that, the knowledge about EQ has to be clarified evidently which is an indicator that indicates the ability to understand and manage emotions of yourself and others. Moreover, among the factors contributing to the formation of emotional intelligence, self-management is one of those five dimensions which is the ability to manage one’s own emotions and impulses(Robbins, 2019) which is also impossible in situations that the HRM department uses emotional intelligence (EQ) to evaluate an employee's job performance. Obviously, HRM's main purpose is to build the professional working style and positive attitude of each employee leading to the company can achieve its goals most effectively and efficiently.With the two main arguments being human behavior that is adaptable and difficulty in controlling emotions, additionally with the main purpose of the HRM department, thus we can deduce that the HRM department using the EQ index to predict behavior and improve job performance of each employee will not produce an accurate outcome "
