A Contingency Approach to Decentralization

After decades of centralization, in 1980 the central government of the Netherlands embarked upon an ambitious project to decentralize the administrative system. It proclaimed a series of general decentralization measures that aimed to improve the performance of the administrative system and to boost local democracy. This article presents the results of research into the effects of these measures. It shows that the decentralization project did not meet the high expectations. This can be explained by the fact that the theoretical framework underlying the decentralization policy was overly simple. The authors present a new framework that represents the contingent character of the effects of decentralization.     

‘Warren Buffet is my cousin’: shaping public understanding of big data biotechnology,direct-to-consumer genomics,and 23andMe on Twitter

Scholars, educators, regulators, pundits, and other observers are advocating for regulation and oversight of direct-to-consumer (DTC) genomic testing. As a result, the technology has been subject of highly visible public and regulatory controversy. In this article, we explore the nature and the shape of the sentiment of public discourse about the DTC company, 23andMe. We conduct a quantitative content analysis and qualitative framing analysis on Tweets. We find that the discourse surrounding DTC genomics and 23andMe is largely positive. We also identify a number of frames users deploy to debate, discuss, and share their experiences with DTC genomics and 23andMe. We argue that these frames create meaning around this emerging technology for its users.

On pseudo-values for regression analysis in competing risks models

For regression on state and transition probabilities in multi-state models Andersen et al. (Biometrika 90:15–27, 2003) propose a technique based on jackknife pseudo-values. In this article we analyze the pseudo-values suggested for competing risks models and prove some conjectures regarding their asymptotics (Klein and Andersen, Biometrics 61:223–229, 2005). The key is a second order von Mises expansion of the Aalen-Johansen estimator which yields an appropriate representation of the pseudo-values. The method is illustrated with data from a clinical study on total joint replacement. In the application we consider for comparison the estimates obtained with the Fine and Gray approach (J Am Stat Assoc 94:496–509, 1999) and also time-dependent solutions of pseudo-value regression equations.

人民币到底被低估了多少?

人民币汇率是近年来国际关注的焦点.本文借助乔翰森(Johansen)协整分析框架,运用行为均衡汇率(BEER)模型和恒久均衡汇率(PEER)模型,探究了人民币实际汇率和名义汇率的均衡水平.论文认为,人民币汇率的确被低估,但幅度最高不超过15%;渐进的"两步走"改革战略是中国推进固定汇率制转向弹性浮动汇率制的最佳选择.     

Positive Effekte sozialen Faulenzens beim Lösen komplexer Probleme

The term “social loafing” refers to a decrease in motivation and achievement in group work due to sinking responsibility of the individual for the groups’ outcome. Recent studies assume a paradoxical relation between motivation and outcome, which should produce better outcome with decreased motivation. The current study addresses this question. Two experiments with N=60 subjects working in groups of 3 are reported. Subjects had to deal with a computer simulated scenario of a fire fighting situation. There was a simple and a more complex version; also, individual responsibility for the groups’ outcome was either given (coactive condition) or not (collective condition). During experiment 1, subjects could only deal with their own section of the scenario; in experiment 2, they were allowed to work on the whole field. Dependent variables were effort (in terms of commands given) and achievement (in terms of space saved). It turned out that under collective responsibility effort was reduced but this did not lead to decreased achievement. Under the complex condition, with decreased effort even an increase in achievement could be demonstrated. Implications for the collective effort model presented by Karau and Williams are discussed.     

A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.     

History matters: The impact of reviews and sales of earlier versions of a product on consumer and expert reviews of new editions

Product reviews are assumed to be based on the observable characteristics of the underlying product. However, in the case of new editions in a product series, the determinants may include signals that originate from the reviews and the sales of editions that precede the focal product edition. Our analysis of 577 video games released in a series between 2000 and 2009 indicates that the reviews of earlier versions carry over to the reviews of the sequel by the same type of reviewer. We also find that expert reviews are influenced by the average review of previous editions by consumers and the average sales of previous editions of the product. This suggests that experts tend to adapt to the taste of consumers. Furthermore, it is found that a lack of consensus, between reviewers of a particular type, weakens the impact of average past reviews, whilst it magnifies the impact of the sales of earlier versions.     

Virtual journey coupled with face‐to‐face exchange: enhancing the cultural sensitivity and competence of graduate students

This study attempted to enhance cultural sensitivity for graduate students at an American and a South African university, using a six‐week online List Serv, email buddy exchange, and two‐week face‐to‐face experience. After the course was over, results of the intercultural developmental inventory, using t‐tests for related samples, showed that there was a significant difference (alpha equals .04) in the universalism and cognitive frame shifting clusters as well as the overall developmental cultural level of sensitivity. Positive trends were noted in the areas of cultural self‐identity enhancement, and a decrease in inflation in the area of perceived intercultural sensitivity was noted.
