On the Generic (Im)Possibility of Full Surplus Extraction in Mechanism Design

A number of studies, most notably Crémer and McLean (1985, 1988), have shown that in generic type spaces that admit a common prior and are of a fixed finite size, an uninformed seller can design mechanisms that extract all the surplus from privately informed bidders. We show that this result hinges on the nonconvexity of such a family of priors. When the ambient family of priors is convex, generic priors do not allow for full surplus extraction provided that for at least one prior in this family, players' beliefs about other players' types do not pin down the players' own preferences. In particular, full surplus extraction is generically impossible in finite type spaces with a common prior. Similarly, generic priors on the universal type space do not allow for full surplus extraction.     

Examination of Interest Inventories Based on Roe's Classification

This article describes the adaptation of two interest inventories translated into English, based on Roe's (1956) classification of occupations. In an analysis based on the responses of 181 participants, the items followed the 6 rules for interest inventory items formulated by Meir and Gati (1981). The Cronbach alpha reliability of the 8 field scores in the 2 inventories ranged between .73 and .91. A Smallest Space Analysis (SSA) on 8 field scores on the Ramak, 8 field scores on the Courses and 6 personality type scores on Holland's (1973) Vocational Preference Inventory (VPI) supported the construct validity of the inventories.     

The brain drain.

The adult human brain weights around three pounds. Yet it is capable of feats that dwarf those of the most sophisticated computers. The sad fact is, those brains are largely wasted in modern organizations. Instead of tapping the full capacity of the human brains that could make our organizations more efficient and effective, we allow them to lapse into an inexcusably large amount of wasted activity. What is needed by the health care field, in a time that demands more with less, is more sensible use not only of its manpower but also of its brainpower.     

Report on the First FTM Conference of the Americas: A Vision of Community

The author reports on the first ever conference (held in San Francisco last summer) devoted entirely to the subject of female-to-male transsexualism (biological females who live as men). Having thrown off the notion that transsexualism refers only to biological males who live as women (MTFs), the newly formed female-to-male transsexual (FTM) community addressed a wide range of topics from “Living Long Term in Transsexual Bodies” to “Gay/Straight Issues” A full day was devoted to presentations of the medical technologies designed to accomplish a transition from female to male. Notably the conference participants began to challenge a disease model of transsexualism and acknowledged the development of “transgender studies” in academia.     

Assessing the long-term effects of EMDR: results from an 18-month follow-up study with adult female survivors of CSA

This 18-month follow-up study builds on the findings of a randomized experimental evaluation that found qualified support for the short-term effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) in reducing trauma symptoms among adult female survivors of childhood sexual abuse (CSA). The current study provides preliminary evidence that the therapeutic benefits of EMDR for adult female survivors of CSA can be maintained over an 18-month period. Furthermore, there is some support for the suggestion that EMDR did so more efficiently and provided a greater sense of trauma resolution than did routine individual therapy.     

Cost-Benefit Analysis of All-Terrain Vehicles at the CPSC1

The present value of the costs of injuries and deaths associated with each unit of a product is a useful number in conducting cost-benefit analysis at the CPSC. Before a remedy is known, this value indicates the approximate amount that it is worth spending on a fix; similarly, if a fix is proposed, this number indicates whether it is cost-justified. The method of analysis is applied to all-terrain vehicles. Injury costs per vehicle are estimated. Determinants of accidents are estimated using a logit regression model applied to surveys of users and of accident victims; this indicates factors associated with accidents, and is used to estimate marginal probabilities. Costs of various vehicle components are estimated using a hedonic price index. This information (injury costs, accident probabilities, and component cost) is combined in a benefit–cost analysis of proposed remedies.     

RISK SOCIETY,MEDIA, AND POWER: THE CASE OF NANOTECHNOLOGY

Risk society theory posits that the transformation of industrial to postindustrial society corresponded with a transformation of societal power structured by capital, to one structured by the ability to define risk. Perceptions of risk are, in part, socially constructed and created through the framing efforts of various institutional actors. The resulting struggle over meaning is particularly acute when the issues contain many unknown elements—as is the case with emerging technologies. Applying insights from media studies, frame analysis, and organizational theory, we analyze coverage of nanotechnology (NT) in popular press, trade, and general science publications. The findings document the extent to which the risks of this emerging technology are presented or ignored across, between, and within organizational subfields. The analysis empirically assesses a key proposition of risk society theory and reveals how institutional processes reflect and reproduce power differentials. We discuss the implications of the empirical findings for sociological theories of risk and society, power, and collective action.     

Activism and the Limits of Symmetry: The Public Relations Battle Between Colorado GASP and Philip Morris

Litigation has forced tobacco companies like Philip Morris to disclose more than 7 million internal documents, including previously confidential public relations plans. We draw from this archive, as well as from activist materials, to demonstrate that, despite vigorous industry efforts to thwart them, activists in this case employed strategies of values advocacy and inoculation and capitalized on economic benefits to persuade publics. This watershed case poses continued challenges for the 2-way symmetrical or mixed-motive theoretical model of public relations. Accounting for public relations activism and understanding its voice in influencing contemporary public debate requires that scholars move beyond this widely accepted model that stresses compromise between activists and organizations. An alternative rhetorical theory of activist public relations is posited to account for groups that refuse to accommodate opponents.
