New aligned-rank test procedures for the composite null hypothesis of no interaction effects (without placing restrictions on the two main effects) against appropriate composite general alternatives are developed for the standard two-way layout with a single observation per cell. Relative power performances of the two new aligned-rank procedures and existing tests due to Tukey (1949) and to de Kroon & van der Laan (1981) are examined via Monte Carlo simulation. Extensive power studies conducted on the 5 × 6 and 5 × 9 two-way layouts with one observation per cell show superior performance of the new procedures for a variety of interaction effects. Simulated critical values for the new procedures are provided in settings where the number of levels for each of the factors is between 3 and 9, inclusive. 相似文献

Rapid developments in social capital and health research require short instruments for large-scale survey studies. The Personal Social Capital Scale (PSCS) is a theory-based and empirically tested instrument with reliability and validity established in the US and China, but it is too long for large-scale survey research. In this study, we described two short versions of the instrument: the PSCS-16 and PSCS-8. The two short scales were evaluated with survey data collected among an adult sample (N = 259) in China. The sample consisted of rural-to-urban migrants and non-migrant rural and urban residents. Cronbach’s alpha coefficients were .90 for the PSCS-18 and .83 for the PSCS-8. Both short instruments satisfactorily fit a two-factor model comprising the bonding capital and bridging capital subscales. The two short scales were highly correlated with the original PSCS (r = .95 for the PSCS-18 and .93 for the PSCS-8 respectively, p < .001 for both); significantly distinguished the migrant subsample from the two non-migrant subsamples; and significantly predicted social capital investment and stress level. In conclusion, the two short instruments PSCS-16 and PSCS-8 were reliable and valid, and can be used in large-scale survey studies to assess personally owned social capital. Further research is needed to replicate their reliability and validity in different cultural settings and to establish the test–retest reliability. 相似文献

While a large body of conversation analytic research focuses on talk in medical settings, a relatively small but important emerging body of research on that subset of medical problems which affect individuals’ ability to produce and comprehend language has been developing. This paper reviews such research on four such medical problems: aphasia, Autism Spectrum Disorder, intellectual disability, and forms of dementia such as Alzheimer’s. This research provides useful insight into the nature of symptoms and the actual communicative competence of the individuals affected, as well as improving our knowledge of the best ways to diagnose, assess, and treat these conditions. 相似文献

We analyzed a process for the annual selection of a Federal agency's best peer-reviewed, scientific papers with the goal to develop a relatively simple method that would use publicly available data to assess the presence of factors, other than scientific excellence and merit, in an award-making process that is to recognize scientific excellence and merit. Our specific goals were (a) to determine if journal, disease category, or major paper topics affected the scientific-review outcome by (b) developing design and analytic approaches to detect potential bias in the scientific review process. While indeed journal, disease category, and major paper topics were unrelated to winning, our methodology was sensitive enough to detect differences between the ranks of journals for winners and non-winners. 相似文献

Till Debt do us Part: A Model of Divorce and Personal Bankruptcy 总被引:1,自引:0,他引:1
The number of personal bankruptcies has increased dramatically since 1990, and a growing number of filers are divorced. While
previous research shows that divorce significantly increases the probability of bankruptcy, these studies assume divorce is
exogenous. This study uses the Panel Study of Income Dynamics to investigate the relationship between divorce and bankruptcy. Single-equation probit results show that divorce significantly
increases the probability of bankruptcy and bankruptcy significantly increases the probability of divorce. However, after
controlling for endogeneity, the effect of divorce on bankruptcy and the effect of bankruptcy on divorce both fall by a significant
amount and are statistically insignificant. The findings suggest that future research needs to more carefully model the role
that financial distress plays within a marriage.

The primary goal of this study was to investigate the association between early adolescents' generalized beliefs about the causes of best friendship deterioration and dissolution and conflict experiences in their own best friendships. An additional goal was to assess whether early adolescents' self-esteem moderated this association. Participants listed their beliefs about the causes of best friendship deterioration and dissolution, indicated whether conflicts described in a series of vignettes had occurred in one of their best friendships, and described two conflicts they had experienced in their best friendships. They also judged the seriousness of the vignette and personally experienced conflicts. As predicted, early adolescents included conflict issues they had experienced personally more frequently in their causal inventories than conflict issues that they had not experienced personally. However, contrary to predictions, the perceived seriousness of the conflicts did not influence their inclusion in participants' causal inventories. While high and low self-esteem adolescents had similar beliefs about the causes of best friendship deterioration and dissolution, low self-esteem adolescents perceived their conflicts as more serious and their friendships as more fragile. 相似文献
