DNA microarray experiments result in enormous amount of data, which need careful interpretation. Biplot approaches show simultaneous display of genes and samples in low-dimensional graphs and thus can be used to represent the relationships between genes and samples. There are several different types of biplots, and these methods need to be evaluated because each plot provides different result. 相似文献

The purpose of this qualitative research was to explore the work experience of middle‐class, Korean full‐time mothers in their 50s. Interviews, observations, and photographs were collected from 11 Korean full‐time mothers to understand their work and career experiences. The data were analyzed by a case study qualitative method of inquiry. The themes that emerged from the data were paths to becoming full‐time mothers, multiple working roles from relationships, dialectical characteristics of work, meaning of full‐time mothering, and regrets and internalized biases for full‐time motherhood. The findings illustrate how full‐time mothers experience a sense of meaning and mattering from their work; how relationships and work are intertwined in their lives; and how gender, social class, and culture influence the work and relationships of full‐time mothers. Implications for counselors and researchers are discussed. 相似文献

The quality of estimation of variance components depends on the design used as well as on the unknown values of the variance components. In this article, three designs are compared, namely, the balanced, staggered, and inverted nested designs for the three-fold nested random model. The comparison is based on the so-called quantile dispersion graphs using analysis of variance (ANOVA) and maximum likelihood (ML) estimates of the variance components. It is demonstrated that the staggered nested design gives more stable estimates of the variance component for the highest nesting factor than the balanced design. The reverse, however, is true in case of lower nested factors. A comparison between ANOVA and ML estimation of the variance components is also made using each of the aforementioned designs. 相似文献

Bayesian estimation for the exponentiated Weibull model under Type II progressive censoring 总被引:1,自引:1,他引:0
Based on progressive Type II censored samples, we have derived the maximum likelihood and Bayes estimators for the two shape
parameters and the reliability function of the exponentiated Weibull lifetime model. We obtained Bayes estimators using both
the symmetric and asymmetric loss functions via squared error loss and linex loss functions. This was done with respect to
the conjugate priors for two shape parameters. We used an approximation based on the Lindley (Trabajos de Stadistca 21, 223–237,
1980) method for obtaining Bayes estimates under these loss functions. We made comparisons between these estimators and the
maximum likelihood estimators using a Monte Carlo simulation study. 相似文献

What Protestant congregations offer spaces for worship and dialogue among persons with different sexual orientations? The academic literature finds or assumes that non-heterosexuals are stigmatized or invisible in theologically conservative congregations and are welcomed in progressive, affirming congregations. This article develops an alternative claim that some conservative or evangelical congregations offer attractive spaces for non-heterosexuals to worship and dialogue. We illustrate with an exploratory study of four congregations in South Korea—two theologically progressive, two evangelical—whose pastors welcomed everybody regardless of sexual orientation or gender identity. The “inclusive-evangelical” congregations retained conservative theology on sexuality (sexual relations only within heterosexual marriage) but offered more empathic dialogue with non-heterosexuals than did most evangelical congregations; they also provided more resources, conventional religious culture, and ties to traditional affective networks than the affirming-progressive congregations. Inclusive-evangelical congregations offer an institutional venue for non-heterosexual Christians in Korea to potentially reconcile three central values: conservative Christianity, traditional (Confucian) affective networks, and expressive individualism. 相似文献

Wide income inequality in a society has been associated with worse aggregate health. Regarding the relationship, often termed as ‘the Wilkinson Hypothesis’, a number of empirical findings and related systematic reviews have reached inconsistent conclusions. In addition, the Scandinavian welfare regime is expected to have better aggregate health indicators in comparison with the other welfare regimes. The expectation is largely based on the Wilkinson Hypothesis because the regime has relatively narrow income inequalities. Again, related empirical findings and systematic reviews have produced inconsistent conclusions. This article reports on two rounds of ‘review of reviews’ (RR) over six previous (systematic) review articles. The first round of RR found that the review articles reached divergent conclusions. The second round of RR over another set of three review articles also demonstrated that their conclusions did not reach a consensus. Neither the hypothesised Scandinavia's good health nor the Wilkinson Hypothesis was given solid empirical backing. 相似文献

Why do donors continue to provide foreign aid despite its failure to help poor countries over the past several decades? While some scholars argue that foreign aid is purely for humanitarian purposes, others assert that such aid serves as a tool to pressure recipient countries into accepting policy concessions. In this study, we subject these arguments to empirical testing using a dataset that integrates the amount of US aid and economic policies of recipient countries for 1995–2012. The findings suggest that aid decisions correspond to the interests of the United States, such as policy concessions in economic and business liberalization. However, an increase in US aid is not directly associated with further economic reforms in recipient countries. We conclude that US foreign aid programmes are strategic in nature and successful not in alleviating economic problems in recipient countries but, at the very least, in buying their policy compliance. 相似文献

This study examined how college students’ levels of planned happenstance skills influenced the relationships among career engagement, career decision self‐efficacy, and career decision certainty. Moderated mediation analysis was used with a sample of 217 Korean undergraduate students. The results indicated that career decision self‐efficacy mediated the relationship between career engagement and career decision certainty. Moreover, the positive indirect effect of career engagement on career decision through career decision self‐efficacy was strengthened as the level of planned happenstance skills increased. In conclusion, college students’ career engagement strengthens their career decision certainty via career decision self‐efficacy when they have enough planned happenstance skills to discover unexpected career opportunities. 相似文献

This study was conducted to develop and initially evaluate the psychometric properties of the Planned Happenstance Career Inventory (PHCI), which aims to assess skill in using chance events to develop career opportunities. After item generation and exploratory factor analysis, 130 original items were reduced to 25 items across 5 factors (5 items for each corresponding factor). Multigroup confirmatory factor analysis confirmed the validity of this 5‐factor structure, and the goodness of fit showed an adequate fit to the observed data for both women and men. Results showed that PHCI subscales correlated moderately and in expected directions with career preparation, career decision‐making self‐efficacy, and career stress. These findings suggest that the PHCI, which assesses 5 dimensions of career‐related planned happenstance skill, shows promise as a useful tool for facilitating understanding of the influence of chance events on career choice behavior. 相似文献

The present study used propensity score analysis to compare the economic well-being of people with and without hearing impairment in the UK. Using nationally representative 2009/10 Life Opportunities Survey, our study found that economic well-being was significantly worse for people with hearing impairment than people without hearing impairment. Hearing impaired people (1) had lower household income, (2) experienced greater difficulties making ends meets, (3) were unable to pay for unexpected but necessary expenses of ?500, and (4) were less likely to work in paid jobs even after accounting for other demographic characteristics. The findings underscore the barriers and discrimination against people with hearing impairment in the UK. Policy measures to increase access and engagement of hearing impaired people should be considered, including increasing investment in better employment opportunities, sign interpretation, and disability benefits. 相似文献
