BENFORD'S LAW AS AN INDICATOR OF SURVEY RELIABILITY—CAN WE TRUST OUR DATA?

This paper analyzes how closely different income measures conform to Benford's law, a mathematical predictor of probable first digit distribution across many sets of numbers. Because Benford's law can be used to test data set reliability, we use a Benford analysis to assess the quality of six widely used survey data sets. Our findings indicate that although income generally obeys Benford's law, almost all the data sets show substantial discrepancies from it, which we interpret as a strong indicator of reliability issues in the survey data. This result is confirmed by a simulation, which demonstrates that household level income data do not manifest the same poor performance as individual level data. This finding implies that researchers should focus on household level characteristics whenever possible to reduce observation errors.     

How star women build portable skills

In May 2004, with the war for talent in high gear, Groysberg and colleagues from Harvard Business School wrote in these pages about the risks of hiring star performers away from competitors. After studying the fortunes of more than 1,000 star stock analysts, they found that when a star switched companies, not only did his performance plunge, so did the effectiveness of the group he joined and the market value of his new company. But further analysis of the data reveals that it's not that simple. In fact, one group of analysts reliably maintained star rankings even after changing employers: women. Unlike their male counterparts, female stars who switched firms performed just as well, in the aggregate, as those who stayed put. The 189 star women in the sample (18% of the star analysts studied) achieved a higher rank after switching firms than the men did. Why the discrepancy? First, says the author, the best female analysts appear to have built their franchises on portable, external relationships with clients and the companies they covered, rather than on relationships rooted within their firms. By contrast, male analysts built up greater firm- and team-specific human capital by investing more in the internal networks and unique capabilities and resources of their own companies. Second, women took greater care when assessing a prospective new employer. In this article, Groysberg explores the reasons behind the star women's portable performance.

Abstract

In an experiment, children in three grade levels (second, fourth, and sixth) viewed four advertisements. The children were shown advertisements with either metaphors in both pictorial and verbal form or a literal equivalent. The sixth graders interpreted more metaphors correctly than the fourth and second graders. In terms of recall of advertised content, the sixth and fourth graders recalled brand names, products, and additional copy better than the second graders. Within each grade level, metaphors did not enhance children's recall of advertised content or perceptions of the understandability of the advertisements and liking of the advertised products. The authors speculate that metaphors are most likely to enhance recall under conditions in which the metaphor serves as a direct representation linking the metaphor to the advertised product. Their findings suggest that advertisers should be aware that young readers may have difficulty interpreting metaphors and that metaphors may not be more effective in terms of children's recall and perception of understandability than literal versions of advertisements.     

From risks to second-order dangers in financial markets: Unintended consequences of risk management systems

This article, along with this special symposium, engages with the lasting significance of Neil Smith's Uneven Development: Nature, Capital, and the Production of Space 25 years after its publication. Few books have made such productive contributions to expanding the horizons of political economy, particularly the spatiality of political economy, as has Uneven Development. This introductory article explores some of these aspects of the book's significance for the readership of New Political Economy; it remarks on the lasting if not growing significance of Smith's intellectual and political contributions two and a half decades after one of his, and the discipline of geography's, crowning achievements. At the same time it foreshadows ways in which the text can continue to push our understanding of the interconnections among nature, capital and the production of space.     

Auswirkungen von betrieblichen Work-Life Balance Maßnahmen auf Unternehmen: Stand der empirischen Forschung

Business practice is generally of the opinion that measures for increasing the employees’ work life balance (WLB) are useful for all parties, i.e. also for the companies. This paper analyzes empirical studies which investigate operational effects of WLB measures in companies. Except of the result of one study, researchers revealed only positive effects of WLB for companies. This statement, however, is insufficient to verify the actual operational effects of WLB measures due to methodical and content deficits. Considering this background, the paper develops implications for future research.     

Customer satisfaction measurement: comparing four methods of attribute categorisations

The issue of how to weight and categorise service attributes has attracted great attention from academics as well as practitioners. The application of an inappropriate method could lead to misleading interpretations and useless or costly actions. We first review several streams of literature concerning the theoretical background of attribute categorisations in relation to customer satisfaction. We then identify four methods that have been developed to categorise attributes into four classes. In the next step we apply these methods in an empirical study. Criteria for distinguishing the considered approaches conceptually and methodologically are proposed, and implications for future research are discussed.     

装置的政治

今天,我们时常把艺术等同于艺术市场,把艺术作品首先定义为一种日用品。艺术在艺术市场的语境中起作用,每一件艺术品都是一种日用品,我们对此已经毫无疑义。然而,艺术仍旧还是呈现给那些没有意愿成为艺术品藏家的人们,事实上这些人仍然是艺术人群中的大多数。具有代表性的展览的观众很少把展出的艺术品视为日用品。与此同时,大量大规模的群展如双/三年展,文献展,博览会等正在不断增加。无论这些展览投入了多么
