Philosophical and health issues are prompting an increasing number of Taiwanese to switch to a vegetarian lifestyle. A study by Lu et al., published in the Journal of Nutrition (Vol. 130, pp. 1591-1596), compared the daily intake of nutrients by vegetarians and omnivores living in Taiwan. Among the nutrients considered was protein. Too little protein stunts growth and interferes with all bodily functions; too much protein puts a strain on the kidneys, can cause diarrhea and dehydration, and can leach calcium from bones and teeth. Independent random samples of 51 female vegetarians and 53 female omnivores yielded the data, in grams, on daily protein intake presented in the Chapter 10 data sets, problem #10.51. Do the data provide sufficient evidence to conclude that the mean daily protein intakes of female vegetarians and female omnivores differ? Perform the required hypothesis test at the 1% significance level. a. Determine and state the type of test that should be performed to answer the above question (two sample t-test, paired t-test, or ANOVA).
A two sample t-test will be performed. b. State the null and alternative hypotheses.
The null hypothesis is that the difference in daily protein intake levels are equal.
The alternative hypothesis is that the difference in daily protein intake levels are not equal. c. Use StatCrunch or SPSS software to perform the

...Scott / CULTURAL-PRODUCTS INDUSTRIES REVIEW / March 2004 10.1177/1078087403261256 URBAN AFFAIRS ARTICLE CULTURAL-PRODUCTS INDUSTRIES AND URBAN ECONOMIC DEVELOPMENT Prospects for Growth and Market Contestation in Global Context University of California, Los Angeles ALLEN J. SCOTT The article begins with a brief definition of the cultural economy. A first generation of local economic development policy approaches based on place marketing and associated initiatives is described. The possibilities of a more powerful second-generation approach are then sketched out with special emphasis on localized complexes of cultural-products industries. An extensive review and classification of these complexes is laid out, and their inward and outward relations to global markets are considered. On this basis, a critical discussion of local economic policy options focused on cultural-products industries is offered. Contrasting examples of development initiatives in major global cities, in selected old manufacturing towns, and in the Multimedia Super Corridor of Malaysia are briefly presented. It is suggested that the growth and spread of localized production agglomerations based on cultural-products industries are leading not to cultural uniformity but to greatly increased diversity at the global level. Keywords: agglomeration; cultural economy; globalization; industrial districts; local economic development; place marketing Over the past decade or so, the industrial profile...

...CHAPTER-BY-CHAPTER ANSWER KEY CHAPTER 1 ANSWERS FOR THE MULTIPLE CHOICE QUESTIONS 1. b The sociological perspective is an approach to understanding human behavior by placing it within its broader social context. (4) 2 . d Sociologists consider occupation, income, education, gender, age, and race as dimensions of social location.(4) 3. d All three statements reflect ways in which the social sciences are like the natural sciences. Both attempt to study and understand their subjects objectively; both attempt to undercover the relationships that create order in their respective worlds through controlled observation; and both are divided into many specialized fields. (5-7) 4. c Generalization is one of the goals of scientific inquiry. It involves going beyond individual cases by making statements that apply to broader groups or situations. (7) 5. b The Industrial Revolution, imperialism, and the development of the scientific method all contributed to the development of sociology. The fourth influence was the political revolutions in America and France — there was no political revolution in Britain at that time. (8-9) 6. d Positivism is the application of the scientific approach to the social world. (9) 7. d Of the four statements, the one that best reflects Herbert Spencer’s views on charity is “The poor are the weakest members of society and if society intervenes to help them, it is interrupting the natural process of social evolution.” While many contemporaries of Spencer’s were...

...Effects of Mega Events on Host Country’s Image: Image of China after the 2008 Beijing Olympic Games Abstract Mega events have intrigued the academia because of the huge impact they have on the host countries. Not only do mega events catalyse urban regeneration, they also have the ability to command international media’s attention. Furthermore, nations have been known to use mega events such as the Olympic Games, FIFA World Cup, and World Fair to rebuild image and draw in tourists to serve the economic development of the region. While the Olympics are one of the most studied mega events, most of them emphasise on the Western perspective probably because only three out of twenty-six Summer Games have been held in Asia. The most recent one is the 2008 Beijing Olympics, which is the focus of this research. In particular, this study aims to explore China’s image change after the event and the influencing factors that contribute to the change. One’s perception and image change are emotional and subjective; therefore, this research can gain a better insight through qualitative approach. Twenty participants from sixteen countries were recruited and interviewed for 20-30 minutes regarding the Beijing Olympics and related news around that time. The findings showed that China achieved moderate success in rebuilding its image in the economic and technological aspects. Many interviewees were impressed by its organising ability and modernisation. However, China failed to change...
