The goals of this study were to examine the effectiveness of emotional reappraisal in regulating male sexual arousal and to investigate a set of variables theoretically linked to sexual arousal regulation success. Participants first completed a series of online sexuality questionnaires. Subsequently, they were assessed for their success in regulating sexual arousal in the laboratory. Results showed that the ability to regulate emotion may cross emotional domains; those men best able to regulate sexual arousal were also the most skilled at regulating their level of amusement to humorous stimuli. Participants, on average, were somewhat able to regulate their physiological and cognitive sexual arousal, although there was a wide range of regulation success. Whereas some men were very adept at regulating their sexual arousal, others became more sexually aroused while trying to regulate. Age, sexual experience, and sexual compulsivity were unrelated to sexual arousal regulation. Conversely, sexual excitation, inhibition, and desire correlated with sexual arousal regulation success. Increased sexual excitation and desire were associated with poorer regulatory performance, whereas a propensity for sexual inhibition due to fear of performance consequences was related to regulatory success. 相似文献

We describe a test statistic for a changepoint in a sequence of repeated measurements. This statistic is non-parametric, and may be motivated from either frequentist or Bayesian considerations. We apply this procedure to data arising from a clinical sleep study of low-energy emission therapy. 相似文献

This paper is the result of a research project which investigated the impact of the U.S. space program on the American economy. Based on their field studies of past space program impacts, the authors develop several conclusions regarding the overall management and strategic planning of large public programs. In this article, the author outlines a structured approach to strategic planning and evaluation which will aid public program managers to respond to the challenge of impact management. 相似文献

This paper reports on an investigation into strategic project management in the UK upstream oil and gas sector. The management process is represented by a set of elements which covers context, content and output and are balanced across financial, internal business, external environment, and learning and innovation perspectives. The paper uncovers elements that appear to explain successful project management and compares these with the elements to which managers pay greatest attention. There appears to be a mismatch between those elements which are associated with success and those receiving significant management attention. 相似文献

Immigrant Occupational Composition and the Earnings of Immigrants and Natives in Germany: Sorting or Devaluation? 下载免费PDF全文
Boris Heizmann Anne Busch‐Heizmann Elke Holst 《The International migration review》2017,51(2):475-505
In this article, the influence of immigrant occupational composition on the earnings of immigrants and natives in Germany is examined. Using data from the German Socio‐Economic Panel Study and the German Microcensus, several relevant concepts are tested. The notion of quality sorting states that the differences in wages that are associated with the immigrant share within occupations are due only to differences in qualification requirements. Cultural devaluation assumes a negative influence over and above that of quality sorting. The findings indicate that both processes are at work. Additional analyses reveal that the impact of immigrant occupational composition is largely restricted to white‐collar occupations, which underlines the importance of considering historical differences between occupation types in classic migration destinations such as Germany. 相似文献

It has been postulated that mitochondrially derived reactive oxygen species (ROS) play a major causative role in aging processes. The primary sources of these oxidants are believed to be complexes I and III of the electron transport chain, with little evidence supporting oxidant formation at complex II (succinate dehydrogenase). Mutation of a complex II protein has, however, been shown to cause increased oxidative stress and decreased life expectancy in the Caenorhabditis elegans mutant mev-1. A recent study by Yankovskaya and colleagues, in which the structure of Escherichia coli succinate dehydrogenase was determined, provides an explanation for these observations. Furthermore, these results suggest possible mechanisms by which electron leakage might occur at this site in the aged organism. 相似文献

In this paper, we use a pseudo-Boolean formulation of the p-median problem and using data aggregation, provide a compact representation of p-median problem instances. We provide computational results to demonstrate this compactification in benchmark instances. We
then use our representation to explain why some p-median problem instances are more difficult to solve to optimality than other instances of the same size. We also derive
a preprocessing rule based on our formulation, and describe equivalent p-median problem instances, which are identical sized instances which are guaranteed to have identical optimal solutions. 相似文献

The article investigates Russian print media coverage of the 2004 presidential elections in the period between January 1 and December 31, 2004. The content of six Russian newspapers is surveyed. The article's methodology is based on a combination of content and frame analysis. The former is used to examine quantitative patterns of coverage as well as to identify what topics and issues received media attention. Frame analysis is employed as the method to examine how news was presented and interpreted. The findings of this study demonstrate that all selected media but the official Rossiiskaia gazeta, in spite of significant differences in their politics, were initially reluctant to express their support for Viktor Yanukovych and raised doubts regarding his candidacy until the end of September when Yanukovych came out in support of the official status of the Russian language. At the same time, throughout the period Viktor Yushchenko was portrayed as the candidate backed by the West and thereby considered automatically unacceptable to Russian interests. Furthermore, the Ukrainian elections were often presented not as an internal Ukrainian affair but as another clash between the West and Russia over zones of influence in the post-Soviet space. 相似文献
