The Access/Impact Problem and the Green and Gold Roads to Open Access

The research access/impact problem arises because journal articles are not accessible to all of their would-be users; hence, they are losing potential research impact. The solution is to make all articles Open Access (OA; i.e., accessible online, free for all). OA articles have significantly higher citation impact than non-OA articles. There are two roads to OA: the “golden” road (publish your article in an OA journal) and the “green” road (publish your article in a non-OA journal but also self-archive it in an OA archive). Only 5% of journals are gold, but over 90% are already green (i.e., they have given their authors the green light to self-archive); yet only about 10–20% of articles have been self-archived. To reach 100% OA, self-archiving needs to be mandated by researchers' employers and funders, as the United Kingdom and the United States have recently recommended, and universities need to implement that mandate.     

Bayesian analysis of directed graphs data with applications to social networks

Summary.  A fully Bayesian analysis of directed graphs, with particular emphasis on applica- tions in social networks, is explored. The model is capable of incorporating the effects of covariates, within and between block ties and multiple responses. Inference is straightforward by using software that is based on Markov chain Monte Carlo methods. Examples are provided which highlight the variety of data sets that can be entertained and the ease with which they can be analysed.     

Blinded sample size recalculation for clinical trials with normal data and baseline adjusted analysis

Baseline adjusted analyses are commonly encountered in practice, and regulatory guidelines endorse this practice. Sample size calculations for this kind of analyses require knowledge of the magnitude of nuisance parameters that are usually not given when the results of clinical trials are reported in the literature. It is therefore quite natural to start with a preliminary calculated sample size based on the sparse information available in the planning phase and to re‐estimate the value of the nuisance parameters (and with it the sample size) when a portion of the planned number of patients have completed the study. We investigate the characteristics of this internal pilot study design when an analysis of covariance with normally distributed outcome and one random covariate is applied. For this purpose we first assess the accuracy of four approximate sample size formulae within the fixed sample size design. Then the performance of the recalculation procedure with respect to its actual Type I error rate and power characteristics is examined. The results of simulation studies show that this approach has favorable properties with respect to the Type I error rate and power. Together with its simplicity, these features should make it attractive for practical application. Copyright © 2009 John Wiley & Sons, Ltd.     

Reason's other: the emergence of the disabled subject in the Northern renaissance

By the late fifteenth century, the debate over the role of reason and the constitution of the human subject freed public discourse from its reliance on God and placed the rational individual at the centre of social and political thought. The emphasis on rationality necessitated a parallel discourse on its opposite—‘reason’s Other'. In this period, representations of disabled people change in response to this new paradigm. Late medieval cultural documents, such as those of Brant and Bosch, employ folly as a metaphorical device, associated with the qualities of Everyman. However, with the rise of renaissance humanism, the benign metaphors of folly associated with the abstract everyman quickly become inscribed on the bodies of those people who would be constructed as reason's ‘Other’—people with intellectual and physical disabilities—and the abstract discourse of folly is transformed into a much more direct representational association of disability with depravity.

What a piece of work is man! how noble in reason! how infinite in faculty! … the paragon of animals! Hamlet II.ii     

所有产品都是利基品牌

什么是“利基品牌”（Niche brand）？作为美国斯巴鲁（Subaru）汽车公司的营销总监,我需要了解这个问题。斯巴鲁只占美国汽车市场份额的2％——显然,至少从数量上来讲,这就是一个利基市场。但数量本身还不足以说明问题。我认为,每个产品品牌都可以是利基品牌。人们绝对不会说,“我想买一辆通用（企业品牌）”,相反,他们会说,“我想买一辆雪佛兰”。     

HIERARCHIES AND CONTROL

This article offers a reinterpretation of Oliver Williamson's transaction-cost efficiency approach to economic organizations. Asserted transaction-cost minimizations are found to be based on the exercise of social control power within hierarchical governance structures. Analysis of transaction-cost economics' "justification" of hierarchical employment relations shows the tenuous nature of Williamson's noncoercive conceptualization of control. His "rationale" for integrated firms, based on his assessment of the control efficiency properties of intrafirm governance structures, is also shown to be problematic. Finally, a network exchange framework is presented as an alternative approach for analyzing economic organizations. This framework builds upon, and moves beyond, insights developed in the "Markets and Hierarchies" story.     

Nonverbal expectancy violations and conversational involvement

A central feature of nonverbal expectancy violations theory is that unexpected behaviors trigger a cognitive-affective appraisal of such behavior, leading to a valencing of the behavior(s) as positive or negative. It has been proposed that communicator reward mediates the interpretation and evaluation of such violations but may be more important when the violative act is ambiguous in meaning than when it is not. Unclear is whether nonverbal behavioral composites introduce greater or less equivocality of interpretation. Two experiments employing multi-cue conversational involvement violations addressed this issue. In the first, dyads (N=51) engaged in a 10-minute baseline interview, after which participants rated each other on several measures of reward valence. One randomly selected member then served as a confederate interviewee during a second interview and either significantly increased or decreased involvement. In the second experiment, reward was manipulated as physical attractiveness, status, and task expertise. Dyads (N = 60) engaged in prolonged problem-solving discussions during which the confederates either committed an involvement violation or not. In both experiments, the involvement changes were sufficiently unexpected, arousing, and distracting to qualify as violations of expectations. Analysis of message interpretations indicated that (1) relative to normal involvement levels, increased nonverbal involvement was interpreted as most immediate/affectionate, receptive, similar, dominant, and composed, and decreased involvement as least so, and (2) reward mediated only the interpretation of formality. High involvement violations in turn produced greater attraction, credibility, and persuasiveness than low involvement violations for high as well as low-reward communicators, as predicted.where Joe Walther and Jim Baesler are doctoral students.
