Little empirical knowledge about unemployed adults exists during a time when this group needs substantial career assistance. Because there is greater empirical understanding of college student career development compared with what is known about unemployed adults, a chi square and analyses of covariance were used to compare the career thinking, self‐efficacy, and interests of 169 unemployed adults seeking public job center assistance with that of 200 college students. Additionally, a diverse sample of 2,444 unemployed adults is demographically reviewed. Unemployed adults reported a higher level of Realistic interests and similar levels of negative career thinking and career decision‐making self‐efficacy compared with college students.  相似文献

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so‐called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they form.  相似文献

The 10-item Attitudes Towards Lesbian and Gay Men Scale was translated into traditional Chinese, with slight modification in item wordings (by replacing the words such as "lesbians" with "female homosexuals" and "gay men" with "male homosexuals"). Data were collected with a convenient sample of 462 Chinese undergraduate students in social work training programmes from three Hong Kong universities. Analysis of the data showed responses to the scale and its two subscales were internally consistent and a one-factor structure was found on the total scale and separately on each of its two subscales. Differences by religious belief and sex were observed using the total scale scores, as in previous studies using this scale. Researchers could consider using this scale with Hong Kong Chinese and in subsequent cross-cultural studies involving a wider range of Chinese respondents.  相似文献

This longitudinal study among ethnic migrants from Russia to Finland (N = 127) examined the relationships between anticipated and perceived discrimination, ethnic and national identities, and outgroup attitudes towards the national majority group. The study included one pre‐migration and two post‐migration assessments. First, associations between the variables studied were tested using a conventional autoregressive sample‐level modelling approach. Second, individual trajectories and the associations between the individual‐level changes in the variables included in the models were tested. Although there were no sample‐level effects over time, there were significant relationships between changes in discrimination and changes in identification and outgroup attitudes at the individual level. The results indicated that changes in perceived discrimination were not reflected in increased ethnic identification. However, participants who perceived higher levels of discrimination after migration than they anticipated before migration were, in the post‐migration stage, more likely to disidentify from and to increasingly show negative attitudes towards the national majority group. The study complements previous research by examining the identity and attitudinal reactions to perceived ethnic discrimination starting from the pre‐migration stage and highlights the value of incorporating both group and individual perspectives to the research on perceived discrimination.

This study used structural equation modeling to examine longitudinal relations among physical health, personality and mood in a sample of 360 college students. Research focused on the longitudinal associations among physical health and mood and their systematic relations with the Big Five personality dimensions of Extraversion and Neuroticism. Longitudinal analyses over successive 1-month intervals revealed lagged reciprocal effects between physical health and negative affect. After controlling for the effect of negative affect, physical health influenced subsequent positive affect, but positive affect did not influence subsequent physical health. Implications of these findings for subsequent research on health, personality, and emotions are discussed.  相似文献

Bilingual speakers generally manifest slower word recognition than monolinguals. We investigated the consequences of the word processing speed on semantic access in bilinguals. The paradigm involved a stream of English words and pseudowords presented in succession at a constant rate. English-Welsh bilinguals and English monolinguals were asked to count the number of letters in pseudowords and actively disregard words. They were not explicitly told that pairs of words in immediate succession were embedded and could either be semantically related or not. We expected that slower word processing in bilinguals would result in semantic access indexed by semantic priming. As expected, bilinguals showed significant semantic priming, indexed by an N400 modulation, whilst monolinguals did not. Moreover, bilinguals were slower in performing the task. The results suggest that bilinguals cannot discriminate between pseudowords and words without accessing semantic information whereas monolinguals can dismiss English words on the basis of subsemantic information.  相似文献

Although children born preterm or low birth weight (PT LBW) are more likely to exhibit behavior problems compared to children born at term, developmental and family processes associated with these problems are unclear. We examined trajectories of maternal depressive symptoms in relation to toddler compliance and behavior problems in families with PT LBW infants. A total of 177 infants (93 boys, 84 girls) and their mothers enrolled in the study during the infant's NICU stay. Data were collected at five time points across 2 years. Assessments of maternal depressive symptoms were conducted at all time points, and toddler compliance and opposition to maternal requests and behavior problems were assessed at 2 years. Toddlers born earlier with more health problems to mothers whose depressive symptoms increased over time exhibited the most opposition to maternal requests during a cleanup task at 24 months, consistent with multiple risk models. Mothers with elevated depression symptoms reported more behavior problems in their toddlers. The study has implications for family‐based early intervention programs seeking to identify PT LBW infants at highest risk for problem behaviors.  相似文献
