College and University Health Care Professionals: An Expanding Team

Abstract

Factors contributing to students' compliance with mass vaccination programs during meningococcal outbreaks have not been well described. A 1997 mass vaccination campaign at Michigan State University provided an opportunity to study such factors. Of 34 024 students in the target population, 17 538 (51.5%) were vaccinated in 5 days. Vaccination rates were higher for women (47.9%) than for men (43.1 %) and higher for on-campus residents (65.3%) than for off-campus residents (35.6%). For each year of students' age beyond 19, the adjusted odds of vaccination were reduced by 0.82. Adjusted odds ratios for vaccination, with White students as the reference group at 1.0, were 1.33 for Asian American students, 0.97 (not significant) for Hispanic students, 0.82 for African American students, and 0.80 for Native American students. Students from the Colleges of Business, Engineering, Communication, and Natural Science had the highest vaccination rates; those from the College of Arts and Letters had the lowest rates.     

The impact of legislator attributes on interest-group campaign contributions

Legislators possess political assets that economic interest groups may find valuable in pursuing their goals. This paper examines the effect these legislative assets have on the campaign contributions made by two large and easily identifiable interest groups: corporations and labor unions. Committee assignment, voting record, and electoral security are significant predictors of both corporate and union contributions to House incumbents, while party affiliation and years in office also influence the behavior of union political action committees.     

Exchange rate regimes and the cross-country distribution of the 1997 financial crisis

We study variations in the severity of the 1997 financial crisis in a sample of 25 developing countries. We use both currency depreciation and stock market returns as crisis measures. Our key findings are that countries that started 1997 with an exchange rate peg experienced significantly greater currency depreciation and significantly lower stock returns than would be predicted from the levels of various macroeconomic indicators.     

Chebyshev's inequality for nonparametric testing with small N and α in microarray research

Summary.  Microarrays are a powerful new technology that allow for the measurement of the expression of thousands of genes simultaneously. Owing to relatively high costs, sample sizes tend to be quite small. If investigators apply a correction for multiple testing, a very small p -value will be required to declare significance. We use modifications to Chebyshev's inequality to develop a testing procedure that is nonparametric and yields p -values on the interval [0, 1]. We evaluate its properties via simulation and show that it both holds the type I error rate below nominal levels in almost all conditions and can yield p -values denoting significance even with very small sample sizes and stringent corrections for multiple testing.     

“Mnandi-licious!” trends in African language usage in South African television advertising

Advertisements in African languages are generally confined to radio, and in that medium are factual, dialogic and direct. When used in television advertising, however, South Africa’s indigenous languages, particularly those spoken by the largest number of people in South Africa (Nguni languages), play a less informative role, being employed rather to index a concretised African essence, African identity or urban style, or a particular reified post-apartheid togetherness and cultural mobility. In this essay, we analyse four recent television advertisements, all using a Nguni language, and reflect on how and why the vernacular is used and to what extent African languages are no longer seen by television advertisers as carriers of information but as exploitable symbols of trustworthiness, multiculturalism, belonging and innovation. Key tropes that emerge as motivating the inclusion of African languages in television advertisements are identified and serve to organise and focus the argument.     

An Outcome Study of Career Decision Self‐Efficacy and Indecision in an Undergraduate Constructivist Career Course

This study explored outcomes in a constructivist career course. Using a pretest‐ posttest design, the authors assessed the empowerment (operationalized as career decision self‐efficacy) and career indecision of 82 culturally diverse college students at a large, midwestern university. Data were analyzed using a multivariate analysis of variance. Results indicated that students reported significant increases in empowerment with no commensurate decreases in career indecision. In addition to shedding light on the nuanced relationship between empowerment or career decision self‐efficacy and indecision, results indicate the potential constructivist career development has to empower culturally diverse college students.     

The ecology of social support in relation to academic and behavioral self-perceptions among African American boys and girls

ABSTRACT

In this research, the ecology of perceived social support was examined across multiple contexts (i.e., parents, teachers, classmates, and close friends) in relation to self-perception indices among African American school-age children. Social support is multifaceted and includes positive regard from others, practical support, and stability of care. While there is ample evidence that levels of perceived social support are predictive of self-perceptions, there is less information regarding ecologies of social support. African American children are subject to disparate discipline in schools which can create discontinuity in social support across home and school. Furthermore, research has suggested African American boys and girls have different experiences and expectations across parent, school, and peer contexts. Hence, the question arises as to what ecologies of social support are more or less impactful, and for whom? Cluster and canonical correlation analyses were employed to identify and create relevant ecologies across adult and peer social support items. The results suggested the following: a) continuous positive social support was associated with enhanced self-perceptions, b) some patterns of discontinuity were particularly germane for self-perceptions, and c) relations between perceived social support and self-perceptions outcomes varied by gender. Practical implications are discussed.     

MARRIAGE MARKET MATCHING AND CONSPICUOUS CONSUMPTION IN CHINA

Visible expenditures which convey higher socioeconomic status may help individuals differentiate themselves in the marriage market when there is competition for partners and imperfect information. We examine a unique dataset of automobile purchasers in China to investigate the extent to which skewed sex ratios influence expenditure decisions for this highly visible commodity. Using a triple difference approach, we show that unmarried male consumers who face an unfavorable sex ratio purchase more expensive, luxury vehicles than their married peers. Lower income borrowers and those residing in regions with the worst sex ratios exhibit the largest relative degree of conspicuous consumption. In addition to the direct cost of consumption signaling, we demonstrate that this behavior generates negative externalities in the form of lower average fuel economy and higher average vehicle weight. As it has worsened sex ratios, status competition and the associated negative repercussions we identify represent unintended consequences of China's one child policy. (JEL O12, E21, J12)     

Product value matrices help firms to focus their efforts

In management theory a gap seems to exist between consumer buying behaviour and the economic life cycles of products. This gap is the subject of this paper using product value matrices (PVMs). Brought together in this paper are some well-known theories dealing with consumer behaviour, buying behaviour and product life cycles (PLCs), in a manner that provides useful information to all firms. Too often it is found that these theories are elegant in isolation, but provide little help in focusing a company's efforts. Consumer behaviour has been researched for many decades, as has product life cycles, but the link between consumer buying behaviour and economic life cycles of products is mystical, with most chief executive officers (CEOs) believing it occurs like magic. The paper initially develops frameworks describing the economic life cycles of products and consumer buying behaviour. The paper then links the frameworks with the product value matrix and illustrates how they can be used in focusing a firm's efforts.
