2 John Dixon is the recently appointed Chief of Police for a major city in the UK. He has inherited a major problem inthat its residents are very concerned with various forms of antisocial behaviour and minor crimes carried out by asmall number of people, which makes living, working, travelling and socialising in the city centre unpleasant ratherthan life threatening. The city’s residents have recently voted for it being one of the five worst cities in the UK in whichto live. There is little or no contact between the police and these residents.The city is split into a number of police districts, each with its own senior officer in charge. Their focus is on theresponse to emergency calls and solving serious crimes in their district rather than the less urgent crimes affectingeveryday living in the city. Response times and serious crime solution rates are the traditional measures by which theirperformance is measured and leave them open to criticism of simply reacting to events. There is little sense of beingpart of a city police force and, consequently, little sharing of information and experience between the different districts.The failure in policing antisocial behaviour in the city is seen as being largely the result of a shortage of resources.There are also important internal and external groups varying in their support or resistance to any necessary changein policing strategy. Key players include the mayor of the city anxious to improve the reputation of the city, the city’spress, traditionally used to highlighting police failures rather than successes and finally the courts of justice, whichare reluctant to take on the increased workload that any moves towards reducing antisocial behaviour would produce.John is aware of the complexity of the problem he faces in changing the way the city is policed to improve the qualityof life of its citizens. He has, however, an impressive track record as a change agent in previous appointments and isconfident that he can bring about the necessary change.Required:(a) Using change management models where appropriate, provide John with a brief report on the nature ofchange needed in the way the city is policed in order to improve the city’s quality of life.

Big Cheese Chairs (BCC) manufactures and sells executive leather chairs. They are considering a new design of massaging chair to launch into the competitive market in which they operate.They have carried out an investigation in the market and using a target costing system have targeted a competitive selling price of $120 for the chair. BCC wants a margin on selling price of 20% (ignoring any overheads).The frame. and massage mechanism will be bought in for $51 per chair and BCC will upholster it in leather and assemble it ready for despatch.Leather costs $10 per metre and two metres are needed for a complete chair although 20% of all leather is wasted in the upholstery process.The upholstery and assembly process will be subject to a learning effect as the workers get used to the new design.BCC estimates that the first chair will take two hours to prepare but this will be subject to a learning rate (LR) of 95%.The learning improvement will stop once 128 chairs have been made and the time for the 128th chair will be the time for all subsequent chairs. The cost of labour is $15 per hour.The learning formula is shown on the formula sheet and at the 95% learning rate the value of b is -0·074000581.Required:(a) Calculate the average cost for the first 128 chairs made and identify any cost gap that may be present atthat stage. (8 marks)(b) Assuming that a cost gap for the chair exists suggest four ways in which it could be closed. (6 marks)The production manager denies any claims that a cost gap exists and has stated that the cost of the 128th chair will be low enough to yield the required margin.(c) Calculate the cost of the 128th chair made and state whether the target cost is being achieved on the 128th chair.

Passage 2Taylor Swift, the seven-time Grammy winner, is known for her articulate lyrics, so there wasnothing surprising about her writing a long column for The Wall Street Journal about the future ofthe music industry. Yet there′ s reason to doubt the optimism of what she had to say "This moment in music is so exciting because the creative avenues an artist can explore arelimitless," Swift wrote."In this moment in music, stepping out of your comfort zone is rewarded,and sonic evolution is not only accepted ... it is celebrated. The only real risk is being too afraid totake a risk at all."That′s hard to reconcile with Nielsen′s mid-year U.S. music report, which showed a 15percent year-on-year drop in album sales and a 13 percent decline in digital track sales. This couldbe the 2013 story all over again, in which streaming services cannibalize their growth from digitaldownloads, whose numbers dropped for the first time ever last year, except that even includingstreams, album sales are down 3.3 percent so far in 2014. Streaming has grown even more than it didlast year,42 percent compared to 32 percent, but has failed to make up for a general loss of interestin music.Consider this: in 2014 to date, Americans purchased 593.6 million digital tracks and heard 70.3million video and audio streams for a sum total of 663.9 million. In the comparable period of 2013,the total came to 731.7 million.Swift, one of the few artists able to pull off stadium tours, believes it′s all about quality."People are still buying albums, but now they′ re buying just a few of them," she wrote. "They arebuying only the ones that hit them like an arrow through the heart."In 2000, album sales peaked at 785 million. Last year, they were down to 415.3 million. Swiftis right, but for many of the artists whose albums pierce hearts like arrows, it′s too late. Sales ofvinyl albums have increased 40.4 percent so far this year, according to Nielsen, and the top-sellingone was guitar hero Jack White′ s Lazaretto. The top 10 also includes records by the aging or dead,such as the Beatles and Bob Marley & the Wailers. More modern entries are not exactly teensensations, either: the Black Keys, Beck and the Arctic Monkeys. None of these artists is present onthe digital sales charts, including or excluding streams. The top-selling album so far this year, by ahuge margin, is the saccharine soundtrack to the Disney animated hit, "Frozen".When, like me, you′re over 40 and you believe the music industry has been in decline since in1993 (the year Nirvana released in Utero), it′ s easy to criticize the music taste of "the kids thesedays," a term even the 23-year old Swift uses. My fellow dinosaurs will understand if they compare1993′s top albums to Nielsen′s 2014 list. But these kids don′t just like to listen to different musicthan we do, they no longer find much worth hearing.The way the music industry works now may have something to do with that. In the old days,musicians showed their work to industry executives, the way most book authors still do to publishers(although that tradition, too, is eroding). The executives made mistakes and were credited with brilliantfinds. Sometimes they followed the public taste, and sometimes they strove to shape it, taking bigfinancial and career risks in the process. These days, according to Swift, it′s all about the socialnetworks. "A friend of mine, who is an actress, told me that when the casting for her recent movie camedown to two actresses, the casting director chose the actress with more Twitter followers," Swift wrote."In the future, artists will get record deals because they have fans--not the other way around."The social networks are fickle and self-consciously sarcastic(see the recent potato saladphenomenon). They are not about arrow-through-the-heart sincerity. That′ s why YouTube made Psya star, but it couldn′t have been the medium for Beatle mania. Justin Timberlake has 32.9 millionTwitter followers, but he′ s no Jack White.In the music industry′ s heyday, it produced a lot of schlock. But it got great music out to themasses, too. These days, it expects artists to do their own promotion and for those who less good atthat than at making music, it may mean not getting heard. For fans it means less good music tostream and download. Well, there′s always the warm and fuzzy world of vinyl nostalgia, I guess.What does the underlined word "that" in PARAGRAPH EIGHT refer toA.Kid' s music taste.B.1993' s top album.C.Nielsen' s 2014 list.D.The music industry.
