Management at Work

Bricks ‘n’ Bats makes children’s toys. The CEO is reorganizing the company to adjust to several changes in the environment. One is the increasing sales of toys online instead of in brick-and-mortar stores. Another is a trend toward less gender orientation in the marketing of toys, as evidenced by Target’s decision to stop labeling many children’s products as for boys or for girls. Yet another change is parents’ growing preference for toys that allow their children to build or make unique creations as well as for educational toys that teach science, math, and other topics. As the CEO considers various organizational structures, he hires you as an expert consultant.

Answer the question posed by the CEO of Bricks ‘n’ Bats.

“Where would it make sense for managers to have wide spans of control?” Check all that apply.

In shipping, where most employees are very experienced and highly trained

In manufacturing, where most employees perform similar tasks that don’t change much over time

In logistics, where employees need to coordinate with several other areas to do their work

In marketing, where most employees and contractors work out of their homes located across the country

Management at Work

Brian, Cedric, Daesun, Nick, and Jake are wool blanket makers, all of whom perform the following steps each year:

Suppose Brian proposes that—instead of each man performing all five tasks—they divide the tasks so that Brian raises and takes care of all the sheep, Cedric shears the sheep to obtain the wool, Daesun prepares the wool to be turned into blankets, Nick makes the blankets, and Jake brings the blankets to market for sale.

The men agree to this proposal and find that specialization yields both positive and negative outcomes.

In the following table, indicate which of the following outcomes reflect likely benefits and which reflect possible drawbacks of the men’s new work structure.

17. Consider the hexadecimal (base 16) number 9a. In a JavaScript program you would write it as: 0x9a. How would you write it in the more familiar base 10? Here is how to solve this.

a.       Recall that a "normal" base 10 number has a ones place, a tens place, a hundreds place, a thousands place, etc. Another way to put it is, it has a 10⁰'s place (10⁰=1), a 10¹'s (10¹=10), a 10²'s place (10²=100), a 10³'s place (10³=1,000), etc. Similarly, a base 16 number has a 16⁰'s place (16⁰=1), a 16¹'s (16¹=16), a 16²'s place (16²=16x16=256), a 16³'s place (16³=16x16x16=4,096), etc.

b.      So the base 16 number 9a has an "a" in the 1s place and a 9 in the 16s place.

c.       It has "a" 1s and 9 16s, so just calculate (a*1)+(9*16).

d.      What number is "a"? Well, base 10 numbers are made with 10 numeral symbols (0 1 2 3 4 5 6 8 9). Similarly, base 16 numbers are made with 16 numeral symbols (0 1 2 3 4 5 6 7 8 9 a b c d e f). An "e" for example has the value of fifteen. Base 2 numbers are made with 2 numeral symbols (0 1). Base 36 uses 36 symbols (0...9 and a...z). In everyday use we get up to base 60 (for measuring time at 60 seconds per minute, 60 minutes per hour) but rather than use 60 different symbols we use other means, as you might have noticed.

e.       You can check your answer in JavaScript using the toString() method:

var num = 128;
num.toString(16);

will provide a string for the base 10 number 128 rendered as a base 16 number. So you can see if toString() will convert your answer and give the string "9a". If it does, you got the right answer.

18.  So far we have looked at calculating a conversion from base 16 numbers into base 10. The same idea applies to converting any base into base 10. What is the base 8 number 7564 in base 10?

19.  What is the binary number 11101111 in base 10?

20.  Next, consider converting base 10 numbers into base 16 or any other base.

Calculate what the base 10 number 1000 is in base 16 (show your work, without using JavaScript). You can check your answer JavaScript using toString() if you like. Here's how to calculate it.

a.       16³=4096, and there are no 4096s in 1000, so there is no fourth digit in the answer, since what you really need are the three digits for 16², 16¹, and 16⁰. How many 16²s are in 1000? 16²=256, so the question then is how many 256s are in 1000? The answer is 3, with a remainder. So the partial answer is: 3 _ _ . Fill in the 2 blanks.

b.      The 3 is the number of 16²s or 256s in 1000, which leaves 1000-3*256 = 232 unaccounted for.

c.       The next digit is for the number of 16¹=16s we need. We can fit 14 of them into 232: 14*16=224, with a remainder of 8 that is not yet accounted for. 14 is written "e" in base 16, so the answer so far is: 3e_ and we have one blank left to fill.

d.      The 16⁰ or 1s place holds the number of 1s we need. 8 of them are needed to fill up the remainder of 8 that we have to deal with, so the answer is: 3e8. Thus

num = 1000;
num.toString(16);

should give the string "3e8".

21.  What is 2000 in base 16 (hexadecimal)? Calculate it without using JavaScript and show your work.

22.  Do this the fast way using toString(). What is the base 10 number 128 in base 2?

23.  Do this the fast way using toString(). What is the base 10 number 128 in base 36? toString() won't go above 36.

24.  What is 200,000,000 in hexadecimal? Do it the fast way in JavaScript unless you have a lot of extra time on your hands.

I need it in java.

Write a program that will print if n numbers that the user will input are or not within a range of numbers. For that, your program needs to ask first for an integer number called N that will represent the number of times that will ask for other integer numbers. Right after, it should ask for two numbers that will represent the Min and Max for a range. Lastly. it will iterate N number times asking for an integer number and for each number that the user input it will present whether the number is or not within the Min-Max range (including their respective value). As an example, if the user inputs: "3 2 5 8 4 2" the output would be:

8 is not within the range between 2 and 5
4 is within the range between 2 and 5
2 is within the range between 2 and 5

Chapter 5 Carter Cleaning Centres—Continuing Case Part 5

Cleaning in a Dynamic Economic Environment

While in college, Jennifer was especially interested in labour forecasting. She learned that a key component of HR planning was forecasting the number and type of workers an organization needed, and to be prepared to re-evaluate those numbers when necessary. Her father had often discussed with Jennifer how his labour demand was dependant on the business cycle—that is, during periods of economic boom when business was soaring more workers needed to be hired and trained, as well as during times of recession when fewer workers were required because the demand for cleaning services had declined. As the economic downturn worsened in 2009, revenues at Carter’s Cleaning Centres fell steeply. Many of their customers were simply out of work and didn’t need (or couldn’t afford) dry cleaning. In the midst of this downturn, Jack knew that he had to get employment costs under control. Realistically, the problem was that there wasn’t much room for cutting staffing in a store. Of course, if a store got very slow, they would double

up responsibilities by having a cleaner also perform the pressing or having the manager work the front counter. If sales only fell 15 to 20 percent per store, there really wasn’t much room for reducing employee head count because each store never employed many people in the first place.

When the economy started to recover and cleaning services were back in demand, Jack faced a labour shortage and needed to find ways to deal with the lack of trained pressers, while at the same time keeping the quality of his services high and customer service levels better than the competition.

Questions

1. What is human resources planning and how will it help Carter’s strategic plans?

2. Describe the steps in the human resources planning process and discuss the important elements within each that will benefit Carter’s Cleaning Centres.

3. Outline three quantitative techniques for forecasting future HR demand. Outline three strategies used to forecast internal HR supply.

4. Assume that Jennifer did not want to terminate any of her employees during periods of economic slowdown. Describe strategies Jennifer might use to deal with the labour surplus?

5. Assume that Jennifer was faced with rising demand for cleaning services and desperately needed to hire more workers, however she faced a labour shortage. Describe strategies she might use to handle a short-age without sacrificing quality or customer service levels.

A common argument from contrarians of the human impact on global warming about the increase in CO2 levels of the atmosphere is that the increase in carbon dioxide by humans is only a small percentage of the total sources of emitted CO2. In other words, the argument is that humans cannot be the cause of the increase in warming of the climate since the added emissions is a small percentage of what is added to the atmosphere from natural forces like volcanoes. In your response, address the following: What are the natural carbon sources and sinks? How does the emission of carbon by humans affect this balance? Why is this argument short-sighted of the feedback mechanisms built into our ecosystem? How would you explain to this contrarian that his argument is missing a larger picture?

You must evaluate the purchase of a proposed spectrometer for the R&D department. The base price is $90,000, and it would cost another $13,500 to modify the equipment for special use by the firm. The equipment falls into the MACRS 3-year class and would be sold after 3 years for $27,000. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The equipment would require an $11,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $50,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 35%.
