This study examined whether variation on the cultural constructs of individualism–collectivism in a sample of predominantly majority culture (i.e., Anglo American) college students accounts for significant amounts of variance in their occupational choices, career plans, and work values. Participants (135 women, 55 men) responded to the “I am” sentence completion method (Kuhn & McPartland, 1954), the Occupational Plans Questionnaire (Hershenson, 1967), and the Work Values Inventory (Super, 1970). Overall, results indicated no significant relationships between level of collectivism and the career-related variables. 相似文献

The methods developed by John and Draper et al. of partitioning the blends (runs) of four mixture components into two or more orthogonal blocks when fitting quadratic models are extended to mixtures of five components. The characteristics of Latin squares of side five are used to derive rules for reliably and quickly obtaining designs with specific properties. The designs also produce orthogonal blocks when higher order models are fitted. 相似文献

H. W. Lewis 《Risk analysis》1988,8(3):411-413
There is a substantial variation in the quality of operators of nuclear power plants, and it is therefore widely believed that regulatory attention is best directed at the worst performers. What is not immediately apparent is a strategy for the optimal allocation of regulatory resources. We study a simple model for this problem, and find that, under reasonable assumptions, the optimal allocation does indeed behave as expected. The proper degree of unbalance, however, depends upon the effectiveness of regulation itself and on the variation among performers, ineffective regulation leading to more concentration on the bottom of the list and a net reduction in attention to the top. Not surprisingly, the optimal strategy is to press toward parity in risk, even if it means allowing some plants to become riskier. This strategy leads to a minimized net probability of accident anywhere. 相似文献

Estimation of Potential Health Effects from Acute Exposure to Hydrogen Fluoride Using a "Benchmark Dose" Approach 总被引:2,自引:0,他引:2
Communities across the United States are examining the manufacture, use, transport, and storage of hydrogen fluoride (HF) near residential areas as a consequence of a major release of HF in Texas in 1987. Reference exposure levels for routine and accidental HF emissions are calculated using existing animal and human data. The approach employs a logprobit extrapolation of concentration-response data to the 95% lower confidence limit on the toxic concentration producing a "benchmark dose" of 1% response (TC01), called a practical threshold. Species-specific and chemical-specific adjustment factors are applied to develop exposure levels applicable to the general public. Using this method, the 1-hr reference exposure level to protect the public against any irritation from a routine emission (REL-1) is 0.7 ppm and the level to protect against severe irritation from a once-in-a-lifetime (REL-2) release is 2 ppm. This approach is compared to a modified "uncertainty factor" approach. 相似文献

This article examines the performativity of intellectual property in digital gaming environments, with a focus on Massively Multi-Player On Line Games (MMOGs). The analysis centers on the creation and management of goodwill, an intangible asset of considerable value to corporations based on affective bonds between consumers, corporations, and their commodities in the marketplace. Most critical analyses of intellectual property consider neither the centrality of goodwill to corporate management of their intellectual properties in digital environments, nor the significance of the legal conditions that structure activity in such contexts. We develop a theoretical framework based on cultures of circulation involving network sociality, circuits of interactivity and the extensibility of the computer/user interface. This enables us to better understand shifting relations of power and reciprocity between corporations and consumers in digital gaming contexts, where the division between player-consumption and player-production is increasingly blurred. Technological capacities for consumers to become producers of gaming content changes the terrain upon which conflicts between corporations and consumers about intellectual property are negotiated and enhances the value of goodwill. An examination of Linden Lab's Second Life – one of the fastest growing MMOGs and the first to affirm players’ intellectual property rights in their digital creations – provides an illustration of both the limits and possibilities afforded by goodwill as a form of emerging governance in game worlds. 相似文献

ABSTRACT This phenomenological study used individual, semistructured, face-to-face interviews to explore motherhood experiences among 15 women receiving public assistance in a large urban area on the West coast. A primary phenomenon observed was that motherhood was described as an experience of identity change, with resulting emotional, behavioral, and sense-of-self changes. Within this broad theme, two categories emerged: the experience and process of change, and consequences of change. It was concluded that motherhood may serve as an important catalyst for change in some women and that the context of poverty is essential for understanding the motherhood experience. These results suggest that interventions aimed at leveraging emerging motherhood identities may be beneficial in setting women on the path out of poverty, drug addiction, and incarceration. Future research should examine the consequences of maternal change within the specific context of the stages of change documented in the recovery process from drug addiction. 相似文献

The analysis of covariance procedure is considered when the observations in each cell are equicorrelated. A correction procedure is given, A computationally easier conservative test statistic is also given. The conservative test statistic allows one to more readily determine the consequences of ignoring correlations, even slight correlations, in the analysis of covariance procedure. The difference of the corrected test and the conservative test is shown to converge in probability to zero. This conservative test is easy to implement on statistical computer packages, It is shown, that for the general correlation pattern, any test involving the regression coefficients of the covariables is an exact test. An example illustrates the procedure 相似文献
