Users versus nonusers of supplements: socioeconomic characteristics

The objective of this research was to determine the socioeconomic characteristics of supplement users versus nonusers. Seven western states (Arizona, California, Idaho, Nevada, New Mexico, Oregon and Wyoming) were surveyed to determine the socioeconomic profile of persons who either use or do not use supplements. Results indicated that 60.2% of the supplement users were female. The largest percentage was 31–40 years of age. By most definitions, supplement users tended to be well educated. Under adverse economic conditions, only a small percentage (7%) of users would give up supplements first when asked to choose from a variety of items that were considered to be nonessential.     

Specialized knowledge and its communication in auditing*

Abstract. The purpose of this paper is to describe certain aspects of specialized knowledge communication in auditing. The paper discusses the possible organizational responses an audit firm could make when competitive markets require efficient knowledge sharing among auditors and when economies of scale opportunities through division of responsibilities exist. Experienced auditors were surveyed about their consultation with others in their firms for specific types of clients and for different phases of audit engagements. In general, the results suggest limits to expertise-related economies of scale in the audit setting studied. The required specialized knowledge seems to be close at hand and accessible in most engagements with little need to consult with nonlocal specialists. When consulted, however, the nonlocal specialists are believed to convey important information. Résumé. Les auteurs ont pour but de décrire certains aspects de la communication de connaissances spécialisées en vérification. Ils traitent des différentes réponses organisation-nelles que peut donner un cabinet de vérification aux exigences des marchés concurrentiels relatives au partage efficient des connaissances chez les vérificateurs et à la possibilité de réaliser des économies d'échelle grâce au partage des responsabilités. Les auteurs ont interrogé des vérificateurs expérimentés dans le but de déterminer s'ils consultaient d'autres vérificateurs de leur cabinet au sujet de certains types précis de clients et pour différentes phases des missions de vérification. De façon générale, les résultats obtenus donnent à penser que les économies d'échelle reliées à l'expertise dans les contextes de vérification étudiés sont limitées. Dans la plupart des missions, il semble que les connaissances spécialisées requises soient à portée de la main et facilement accessibles, sans qu'il soit nécessaire de consulter des spécialistes de l'extérieur. On croit cependant que les spécialistes de l'extérieur livrent de l'information importante lorsqu'ils sont consultés.     

Consumer health beliefs and food supplement use by the elderly

Seven western states in the U.S.A. were surveyed by mail and telephone to assess consumer-health beliefs and the use of food supplements (vitamins and minerals) as part of the overall western region project. A 57.9% return resulted in a sample size of 1,730 adults and 528 of these were 60 years of age and over. The sample included significantly greater numbers of regular users of vitamins and mineral supplements than non-users or occasional users. More women than men were regular users. Compared with those who never used vitamin and mineral supplements, regular users had distinct patterns of health beliefs and practices. Regularly, they relied heavily on the medical profession for general health information. They obtained supplement and diet information from diet books and periodicals and also believed that taking vitamins and minerals prevented serious illness, reduced stress, prevented colds, skin problems, heart attacks, cancer, and other health problems. While they believed their overall well-being was improved through the use of supplements, their responses did not indicate that use of supplements ensured good health or that the current food supply filled nutritional needs. Conclusions are that specific educational programmes about the value and use of food supplements need to be designed for the target audience. Furthermore, all professionals who work in the large array of food service positions should share the responsibility for providing accurate information and advertising.     

Vitamin supplementation practices: health/nutrition education implications

A sample of 310 supplement users, 216 nonsupplement users and 247 inconsistent (user/nonuser) supplementers were followed for 18 months to examine the consistency of supplementation. Since supplementation is often not required for a healthy diet, factors associated with persistence or stability of supplement use have implications for appropriate health/nutrition education. Consistent supplementation (at least 18 months' duration) was associated (P < 0·01) with (i) female sex, (ii) health beliefs in the efficacy of supplementation, (iii) seeking health information from physicians, nurses, dietitians and nutritionists, (iv) using periodicals, TV/radio and books for sources of nutrition information, (v) older age, (vi) higher income and (vii) higher levels of education. Nonusers were more likely to attribute health to chance on the Multidimensional Health Locus of Control scale, and inconsistent users were more likely to have experienced a change in employment status, relocation to another town/city and a higher number of ‘change’ events in the previous 18 months. Based on the characteristics of the consistent supplement user, ‘academic controversy’ may be an effective educational strategy to employ, if changes in supplementation attitudes and beliefs are desired.     

Rhetoric in Economic Research: The Case of Gender Wage Differentials

Scientific rhetoric can have a profound impact on the perception of research; it can also drive and direct further research efforts. What determines whether results are discussed in a neutral or a judgmental way? How precise and convincing do results have to be so that authors call for significant policy changes? These questions are in general difficult to answer, because rhetoric on the one hand, and content and methodology of the paper on the other, cannot be separated easily. We therefore used a unique example to examine this question empirically: the analysis of gender wage differentials. Here, the Blinder–Oaxaca decomposition represents a standard research method that compares male and female earnings, holding observable factors constant. We analyzed close to 200 papers to investigate what drives authors to talk about discrimination, whether and when they call for policy activism, or when they are more hesitant to do so. Our results show that American authors are more reluctant to refer to discrimination. So are women, but only with respect to the titles of their papers. Furthermore, we find that the better the data and method used in a paper, the more likely an author is to assign his/her estimate of unequal wages to discrimination. The contrary is true the higher the prestige of the author or the research outlet.     

Effect of a Class Action Suit on Consumer Repurchase Intentions

This study examines willingness to repurchase a Toyota among 335 Toyota owners, 246 who had participated in a class action suit against Toyota and 89 who had not participated. It also examines attitudes toward auto dealers and manufacturers and includes a psychographic measure of global consumer loyalty. Respondents were interviewed one to two years after participants had received a cash settlement to compensate for illegal overcharging. Multivariate analysis indicates that compared to nonparticipants, settlement participants, especially those satisfied with the settlement, were more willing to repurchase a Toyota and were less positive in their attitudes toward the Toyota manufacturer. Positive attitudes toward the Toyota manufacturer and dealers were associated with higher repurchase willingness, while positive attitudes toward other dealers and manufacturers were associated with lower repurchase willingness. Consumer loyalty was associated with higher repurchase willingness. These findings and their implications are discussed in terms of several theoretical frameworks.
