Statistical inference for aggregates of Farrell-type efficiencies

JOURNAL OF APPLIED ECONOMETRICS, Issue 7 2007
Léopold Simar
In this study, we merge results of two recent directions in efficiency analysis research,aggregation and bootstrap,applied, as an example, to one of the most popular point estimators of individual efficiency: the data envelopment analysis (DEA) estimator. A natural context of the methodology developed here is a study of efficiency of a particular economic system (e.g., an industry) as a whole, or a comparison of efficiencies of distinct groups within such a system (e.g., regulated vs. non-regulated firms or private vs. public firms). Our methodology is justified by the (neoclassical) economic theory and is supported by carefully adapted statistical methods. Copyright © 2007 John Wiley & Sons, Ltd. [source]


The Impact of Synchronicity and Civility in Online Political Discussions on Perceptions and Intentions to Participate

JOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 3 2005
Elaine W. J. Ng
Using a mixed-model factorial design, a laboratory experiment (n=153) was conducted to investigate the effects of two features of CMC-synchronicity and civility-on perceptions of online political discussions and discussants. Results indicate that the synchronous versions of the discussions were perceived as more informative and persuasive than the asynchronous versions. Discussants in the uncivil versions of the discussions were perceived as more dominant and less credible. However, neither synchronicity nor civility had a significant impact on people's intentions to participate. The results stand in contrast to those of previous content analysis research, suggesting the importance of studying perceptions in future research. The implications of the findings for online political communication are discussed. [source]


Reaffirmation of Behavioral Approaches to Depression Treatment

CLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 4 2009
Manuel Barrera Jr
This meta-analytic review improved on the methods and scope of similar reviews but reached the same conclusion that behavioral activation (BA) therapies for adult depression are much more effective than control conditions and comparable with cognitive-behavioral interventions. Future research should strengthen our understanding of the mechanisms that account for the effectiveness of BA approaches and should provide more evidence on long-term maintenance. The resurgence of interest in BA was attributed to pioneering work of Lewinsohn and the components analysis research of Jacobson and colleagues, who demonstrated the effectiveness of behavioral elements of depression treatment relative to cognitive elements.

The Emergence, Maintenance, and Dissolution of Structural Hole Brokerage Within Consortia

COMMUNICATION THEORY, Issue 3 2004
J. David Johnson
This essay focuses on the emergence, maintenance, and dissolution of structural hole brokerage within consortia. The difficulties in forming consortia are well known. Many are associated with the natural structural hole that exists between the parties. Approaches to this problem have been hampered historically by theoretic traditions that have focused on either classic system benefits or more contemporary market consideration of individual interests. Here the author develops propositions concerning the emergence, maintenance, and dissolution of these relationships, focusing on four central factors drawn from different theoretic traditions: homophily, trust, the balance between threats and shared interests, and the balance between differentiation and integration. The author then discusses the implications of this integrated theoretical framework for researcher-practitioner relationships as an exemplar and for trends in network analysis research. [source]
