The purpose of this study was to examine resilience and decision‐making strategies as predictors of difficulties experienced during the career decision‐making process. College students (N = 364) responded to measures of resilience, career decision‐making strategies, and career decision difficulties. Results indicated that resilience and decision‐making strategies accounted for 46% of the variance in career decision difficulties. Resilience had a greater influence on problems encountered during decision making than on problems encountered at the outset of the process. Different decision‐making strategies appeared to be related to difficulties encountered at different stages of the decision‐making process. For example, aspiration for an ideal occupation was positively associated only with lack of readiness. Procrastination was the only strategy related to all three decision difficulties: lack of readiness, lack of information, and inconsistent information. The results indicated the importance of decreasing procrastination at all stages of decision making and the need to promote resilience to deal with decision difficulties.  相似文献

The purpose of this article is to introduce and explore the narrative strategy of queer blindfolding. Utilizing psycho-discursive qualitative methodology, the authors will draw from a case study to demonstrate how some beneficent, well-intended persons who identify as heterosexual adopt the narrative strategy of queer blindfolding as they negotiate the discourse of heteronormativity. We will map this narrative strategy, compare and contrast it to racial colorblindness, and unpack the accompanying intra-psychic conflict and defense mechanisms that are utilized by the participant in the case study. We will also demonstrate how this discursive strategy positions participants within systemic heterosexism.  相似文献

A national survey among religious public relations practitioners working for mainstream Protestant Christian churches was undertaken to examine strategic options in a conflict or crisis. Religious public relations professionals tend to employ collaborating, contending or compromising in a conflict with a given public, while they are likely to use concession or corrective action in a crisis. Internal contingent factors are mostly associated with accommodating, avoiding, concession or corrective action strategies, while contending is most often correlated with external contingent factors.  相似文献

The management of a panel block shop in a shipyard is a complex process that entails the largest amount of work and in which many decisions are involved. Shipbuilders have considered the process as a bottleneck since every panel for every ship must be processed through the shop. The objective of this research is to carry out a materials flow analysis to maximise process productivity and to place simulation optimisation technology in the hands of decision makers, such as production planners and supervisors. In this article, a production execution planning system is proposed for panel block operations utilising discrete-event simulation and simulated annealing. The simulation model was validated using a real production scenario and the comparison showed a very favourable agreement between the actual panel shop and the simulation model. The proposed system supports production planners by general dispatching rules and optimisation to make better scheduling decisions on the shop floor. The system will provide a complete schedule that is at least as clear and accurate as any schedule currently obtained.  相似文献

It is common that SMEs recognize low-risk technological arbitrage opportunities in mature technologies, enter the global market, and occupy significant market shares. This opportunity is characterized by imitable technology complexity, market insignificance for oligopoly companies, and technology maturity. We propose a new and systematic method to recognize the most appropriate low-risk technological arbitrage opportunities for SMEs. The four-phase opportunity recognition procedure consists of technology complexity analysis, market appropriateness analysis, technology maturity analysis, and organizational fit analysis using empirical measures and analytic tools. An illustrative example of a company searching for technological arbitrage opportunities in semiconductor equipment is provided.  相似文献

A Bayesian approach is considered for identifying sources of nonstationarity for models with a unit root and breaks. Different types of multiple breaks are allowed through crash models, changing growth models, and mixed models. All possible nonstationary models are represented by combinations of zero or nonzero parameters associated with time trends, dummy for breaks, or previous levels, for which Bayesian posterior probabilities are computed. Multiple tests based on Markov chain Monte Carlo procedures are implemented. The proposed method is applied to a real data set, the Korean GDP data set, showing a strong evidence for two breaks rather than the usual unit root or one break.  相似文献

Site licensing of electronic journals has revolutionized the way academic information is distributed. However, many librarians are concerned about the possibility that commercial publishers might abuse site licensing by the practice of bundling. In this paper, we analyze how bundling affects journal pricing in the market of scientific, technical, and medical electronic journals and offer a novel insight on the bundling of a large number of information goods. We find that (i) when bundling is prohibited, surprisingly, industry concentration does not affect prices; (ii) when bundling is allowed, each publisher finds bundling profitable and bundling increases industry profits while reducing social welfare; and (iii) any merger among publishers already active in the market is profitable but reduces social welfare.

Abstract

Objectives: To evaluate the association between handgrip strength and erectile dysfunction (ED) in community-dwelling older men.

Methods: This cross-sectional study included 1771 participants of the Dong-gu Study. Handgrip strength was measured with a handheld dynamometer. ED was assessed with the Korean version of the International Index of Erectile Function (IIEF). ED was categorized as none to mild (IIEF-EF scores of 13–30) and moderate to severe (IIEF-EF scores of 0–12). Multivariable logistic regression was conducted with adjustment for potential confounders.

Results: The proportion of men with moderate to severe ED was 48.8%. The age-adjusted ED score increased with increasing quartile of handgrip strength (11.0, 12.4, 13.4, and 14.0 in the lowest, second, third, and highest quartiles, respectively). After adjustment for potential confounders, greater handgrip strength was associated with a lower risk of ED (odds ratio (OR): 0.82 per 5?kg; 95% confidence interval (CI): 0.74–0.90). In addition, a high level of moderate to vigorous physical activity was associated with a lower risk of ED (OR: 0.75; 95% CI: 0.61–0.93).

Conclusion: In this study, aging men with greater handgrip strength had a lower risk of ED. This result suggests that reduced physical functioning may contribute to ED.  相似文献

The association between daily variations in urban air quality and mortality has been well documented using time series statistical methods. This approach assumes a constant association over time. We develop a space-time dynamic model that relaxes this assumption, thus more directly examining the hypothesis that improvements in air quality translate into improvements in public health. We postulate a Bayesian hierarchical two-level model to estimate annual mortality risks at regional and national levels and to track both risk and heterogeneity of risk within and between regions over time. We illustrate our methods using daily nitrogen dioxide concentrations (NO2) and nonaccidental mortality data collected for 1984-2004 in 24 Canadian cities. Estimates of risk and heterogeneity are compared by cause of mortality (cardio-pulmonary [CP] versus non-CP) and season, respectively. Over the entire period, the NO2 risk for CP mortality was slightly lower but with a narrower credible interval than that for non-CP mortality, mainly due to an unusually low risk for a single year (1998). Warm season NO2 risk was higher than cold season risk for both CP and non-CP mortality. For 21 years overall there were no significant differences detected among the four regional NO2 risks. We found overall that there was no strong evidence for time trends in NO2 risk at national or regional levels. However, an increasing linear time trend in the annual between-region heterogeneities was detected, which suggests the differences in risk among the four regions are getting larger, and further studies are necessary to understand the increasing heterogeneity.  相似文献
