The Sociological Literature on Nuclear Issues*

In this paper we address the question of the existing and potential role of sociologists in the nuclear debate by first sketching some of the major nuclear issues, second by guaging the extent of professional attention which sociology has focused on nuclear issue. Our focus is on the professional sociological literature. In addition to it there is a vast peace literature which ranges from academic studies to newsletters and propaganda pieces. Sociologists may contribute heavily to the peace literature and be active in the peace or relatede campaigns, but we exclude these activities from our study. We view them as actions which sociologists do in their roles of concerned citizens. Our focus here is on the professional sociological literature and our comments pertain solely to it. We select thirteen journals to represent various aspects of this literature and review all issues from 1945 to the present to guage the coverage of nuclear issues in the sociological literature.     

Negotiating the Superfund: Are Environmental Protection Agency regional officials willing to bargain with states?

Negotiation and bargaining are important activities in the implementation of intergovernmental public policies. Given the design of environmental policy, intergovernmental negotiations are an essential part of the interaction of environmental program managers. This study examines the willingness of Environmental Protection Agency (EPA) regional officials to bargain with their state counterparts in the national Superfund program. A model of working relationships is developed to analyze the negotiating behavior of regional EPA officials. The findings of this study indicate that both strategic (trust, involvement) and structural (relations with EPA headquarters, state program capacity, and state political context) factors are associated with whether or not regional officials are willing to negotiate with state-level administrators. The implications of these findings for the national Superfund program, the larger context of intergovernmental management, and larger themes in public administration are discussed in the conclusion of this paper.     

Sample Size Requirements and Study Duration for Testing Main Effects and Interactions in Completely Randomized Factorial Designs When Time to Event is the Outcome

In this paper, we develop the methodology for designing clinical trials with any factorial arrangement when the primary outcome is time to event. We provide a matrix formulation for calculating the sample size and study duration necessary to test any effect with a prespecified type I error rate and power. Assuming that a time to event follows an exponential distribution, we describe the relationships between the effect size, the power, and the sample size. We present examples for illustration purposes. We provide a simulation study to verify the numerical calculations of the expected number of events and the duration of the trial. The change in the power produced by a reduced number of observations or by accruing no patients to certain factorial combinations is also described.     

Personality traits and knowledge sharing

In this paper, we describe an empirical study that relates three personality traits (agreeableness, conscientiousness and openness) to knowledge sharing. In the existing literature considerable attention has been paid to managerial influences on knowledge sharing, technological support through information and communication systems, or individual characteristics like motivation or the perception of conflict of interest or vulnerability. Instead we concentrate on the role that personal dispositions play in individual’s knowledge sharing behavior. By means of structural equation modeling with PLS, we discover significant correlations between the personality traits and knowledge sharing within teams of an engineering company. Our results clearly contribute to the existing literature, as they offer empirical evidence of the impact of enduring individual characteristics on knowledge sharing.     

Characterization of minimax linear estimators in linear regression

Two characterization theorems of the minimax linear estimator (Mile) are proven for the case, where the regression parameter varies only in an arbitrary ellipsoid. Furthermore, the existence, uniqueness and admissibility of Mile are shown. The explicit determination of Mile is carried out for a special case.
