(Solution) Although women hold slightly more than half of US managerial positions, they hold far fewer of the top executive positions.
Although women hold slightly more than half of US managerial positions, they hold far fewer of the top executive positions. To counteract this imbalance, some colleges are offering executive education courses for women only. Participants, such as Johson & Johnson, praise these programs for helping women network and gain confidence. What do you think of these programs? Are they ethical? Would you feel differently if they were held for men only? Why? Support your opinion with concrete examples from your own and outside research. Document your answer using APA format.

Waters, Inc. acquired 10% of Denton Corporation on Jan. 1, 2012 for $210,000 although Denton’s book value on that date was $1,700,000. Denton held land that was undervalued by $100,000 on it’s accounting records. During 2012, Denton earned a net income of $240,000 while paying cash dividends of $90,000. On January 1, 2013, Waters purchased an additional 30 percent of Denton for $600,000. Denton’s land is still undervalued on that date, but then by $120,000. Any additional excess cost was attributable to a trademark with a 10 year life for the first purchase and a 9-year life for the second. The initial 10% investment had been maintained at cost because fair values were not readily available. The equity method will now be applied. During 2013 Denton reported income of $300,000 and distributed dividends of $110,000. Prepare all of the 2013 journal entries for Waters.

According to conflict theorists, the persistence of social class inequality can be linked to the educational institutions in the United States. Although education is asserted to be a social equalizer, many argue that the educational system is a mechanism of social reproduction that maintains social inequality rather than ensuring equality of opportunity. In this discussion, you will read Chapter Four of the text, Introduction to Sociology, and review the articles, Foundations of Educational Inequality and the Ordering Regime chapter from the book, The Shame of the Nation. Answer the following questions: •What factors influence the quality of education that an individual receives? •How is social class reproduced through the educational system? •How is this continuing educational inequality impacting other social institutions?

Modern Suits Rental has been in business for four years. Because the company has recently had a cash flow problem, management wonders whether there is a problem with receivables or inventories. Here are selected figures from the company’s financial statements (in thousands): 2011 2010 2009 2008 Net sales 2011-$288.0 2010-$224.0 2009-$192.0 2008-$160.0 Cost of goods sold 2011-180.0 2010-144.0 2009-120.0 2008-96.0 Accounts receivable (net) 2011-48.0 2010-40.0 2009-32.0 2008-24.0 Merchandise inventory 2011-56.0 2010-44.0 2009-32.0 2008-20.0 Accounts payable 2011-26.0 2010-20.0 2009-16.0 2008-10.0 Compute the receivable turnover, inventory turnover, and payables turnover for each of the four years, and comment on the results relative to the cash flow prob- lem that the firm has been experiencing. Merchandise inventory was $22,000, accounts receivable were $22,000, and accounts payable were $8,000 in 2007. (Round computations to one decimal place.) I have all of the answers except the receivable turnover and inventory turnover for the 4 years. I have attached the document that I have completed so far.Year Receivable Turnover Inventory Turnover Payables Turnover Net Sales / Avg Accts Receivable COGS / Avg Inventory COGS +/- Chng in Inv / Avg Accts Payable 2008: $160 = 7.0 times $160 = 4.6 times $160 $96 - $2 = 10.4 times ( $24 + $22 ) / 2 ( $20 + $22 ) / 2 ( $10 + $8 ) / 2 2009: $160 = 6.9 times $160 = 4.6 times $160 $120 + $12 = 10.2 times ( $32 + $24 ) / 2 ( $32 + $20 ) / 2 ( $16 + $10 ) / 2 2010: $160 = 6.2 times $160 = 3.8 times $160 $144 + $12 = 8.7 times ( $40 + $32 ) / 2 ( $44 + $32 ) / 2 ( $20 + $16 ) / 2 2011: $160 = 6.5 times $160 = 3.6 times $160 $180 + $12 = 8.3 times ( $48 + $40 ) / 2 ( $56 + $44 ) / 2 ( $26 + $20 ) / 2 Clearly Modern Suits Rental is carrying too much inventory for its level of business. The inventory turnover ratio has declined from 4.6 times to 3.6 times, which means the company has been investing increasing amounts of cash in inventory. The company can improve its cash flow by reducing inventory. Also, payables turnover decreased, which means the company is paying its bil s in less time. Management should investigate obtaining bet er terms from suppliers. The receivable turnover, on the other hand, has remained relatively constant over the four years. Though it might be improved, it has not worsened significantly.

I worked for Holland America Cruise line in Alaska commonly known as Gray Line of Alaska. The company’s mission statement was “through excellence we create once-in-a-lifetime experiences every time.” The company provided tour packages that highlighted the many attractions of Southeast Alaska. One of the most popular shore excursions is Saxman Native Village located on Revillagigado Island, the location of the Tlingit Indian Tribe who are the original settlers of Southeast Alaska. First you view a short video that introduces you to the culture and history of Saxman. Secondly, the tourists are enlightened by the true culture of the Tlingit Indians through native dancing and carving of Totem Poles. Many of the brochures of Alaska state that Saxman Native Village has one of the largest gatherings of totems in the world. The major concern was to achieve its mission while creating the greatest demand for the Holland American’s Cruise Line tours and excursions. The desired goal was for tourist to prefer Holland America Cruise Line over its competitors Princes, Carnival, and Celebrity Cruise Line for their vacation excursions. The survey research approach was used to find out what their customers desired, liked and disliked. This was accomplished by passing out small brief survey cards to the clients (tourist) after the tours while the experience was still fresh in their minds. The customer feedback allowed the company to enhance its programs for improved customer satisfaction. Once the data obtained from the survey was compiled then analyze the company knew rather they should increase training, eliminate tours or dismiss some personnel. Because we consistently stayed busy and remained the tours of choice, we felt that we were using the optimal marketing action had been taken to achieve the mission. Understand that at that time computer generated requests were not used by the organization, and we were in a more rural area of Alaska where reception was not the best.

Zippy Quick, in his bright suit and straw hat, walked briskly into the large building complex to see the I need answer all questionsCase Study Wk #3: A Free Lunch? Zippy Quick, in his bright suit and straw hat, walked briskly into the large building complex to see the superintendent (Super) about her heating, ventilating, and air conditioning (HVAC) equipment. Zippy said “How’d you like to hear my scheme for you to make money from nothing and then end up with some new equipment that you can effectively use?” Well, the Super was interested but suspicious. “What do you mean, I have to put up no money and end up with new equipment I can keep?” “Correct, I’d have the specialists come in here and do the installation and startup of the equipment. You pay nothing, AND, you’d be making money in a year.” “Where’s the catch?” exclaimed the Super. “NONE, no catch” said Zippy, “Just sign a three-year contract to split 50/50 any savings the equipment generates on the use of your HVAC equipment plus pay for a service contract for the equipment’s maintenance. We will take out the loan for the equipment and installation and pay off the loan with our share of the savings. After three years the equipment is yours. You’ll only be giving us some of the money you are paying the power company for electricity. The service contract for the equipment is $15,000 per year, but think of your peace of mind!” The Super is suspicious of Zippy, but he seems to know HVAC equipment. The deal he is offering seems to be risk free if she gets a clause in the contract that gets the equipment removed at no cost after the first year if she is not seeing cash flow in excess of $15,000 to cover the maintenance contract. Based on her own research in response to Zippy’s claims and some questions she asks him, she finds the following details to use in trying to evaluate Zippy’s offer: • The combined horsepower (HP) for the fans and blowers in the HVAC system total 400 HP. The system currently runs at capacity 100% of the time. • Most systems are overdesigned. A 10% reduction from maximum speeds is possible without impacting performance if fixed speed motors and controls were originally used to drive the blowers. This system was designed that way. • Zippy claims that with his equipment (variable speed drives and controls for the motors) the system will run at 20% of capacity at least 45% of the time. For example, on nights, weekends, and holidays, there is little need for heating and cooling. • While not part of Zippy’s pitch, running the fans and blowers at less than capacity will extend their life from about 7 years to 10 years, which is also the life for Zippy’s system. • Electricity is currently costing $.12 per kilowatt hour. • All the fans in the HVAC system are centrifugal—thus the effective HP is a cube of the speed (see Figure 17-1). This implies at 90% speed, the required HP is 0.9 3 times the required horsepower at 100% of capacity. Note that at 20% speed, the required HP is actually 10 HP rather than the 3.2 HP predicted by 0.2 3 times 400 HP. • One horsepower requires 748 watts.
