Career decision-making difficulties among career-decided college students

The procedures developed by Gati and colleagues to interpret scores in the Career Decision Difficulties Questionnaire were implemented to examine difficulties’ profiles among self-identified decided college students who reported being either comfortable or uncomfortable with their career choice. Of the 583 participants, 92.5% were career decided and 7.5% were undecided. Close to half (47.2%) of the career-decided students self-identified as uncomfortable with their career choice and reported similar career decision-making difficulties as their undecided peers. The most salient difficulties among decided uncomfortable students were general indecisiveness and lack of knowledge regarding occupations and the decision-making process. Greater difficulties related to lack of knowledge about oneself, and internal conflicts predicted membership in the decided uncomfortable group versus the decided comfortable group. Results indicated that career-decided students are not a homogenous group. Implications of the findings for career counseling with decided uncomfortable college students are discussed.     

Foraging for patchily-distributed leaf miners by the parasitic wasp,Dacnusa sibirica

Summary We studied the rules used by the female parasitoid,Dacnusa sibirica Telenga (Hymenoptera: Braconidae), for deciding when to leave a tomato leaflet on which she is searching for larvae of the leafminer,Liriomyza bryoniae Kalt. (Diptera: Agromyzidae). Females would deposit a marking pheromone on the leaflet and would leave the leaflet when the amount of the pheromone accumulated to the thresholdL, which is proportional to the amount of search effort on the leaflet.L appears to increase with host density since it rises after every encounter with a host (or mine).D. sibirica would employ an area-concentrated search, which is advantageous in foraging for hosts showing a clumped distribution.     

Prevalence rate of DSM mental disorders among adolescents living in residential group homes of the French Child Welfare System

Purpose

To determine the prevalence of some major mental disorders among adolescents living in a residential group home and the distribution of these disorders by gender.

Method

The participants included 183 adolescents (13–17 years old) living in residential group homes of the Child Welfare System in the county of Bouches-du-Rhône (South of France). A structured psychiatric Diagnostic Interview Schedule for Children was used to assess the existence of Anxiety Disorder (AD), Major Depression (MD), Conduct Disorder (CD), Eating Disorder (ED), Enuresia (En), Psychosis Screen (PS) and Attention Deficit Hyperactivity Disorder (ADHD) among the study participants over the six-month period before the assessment was taken. The existence of Suicide Attempts (SA) during the lifetime of each child was also assessed.

Results

Of the youths qualified, 48.6% as having at least one psychiatric disorder during the last six months (AD: 28.4%; CD: 15.3%; MD: 14.8%; PS: 18.6%; ADHD: 3.8%), and SA have been reported in 23% of them. Females were more affected than boys (p < 0.001) with 64.9% having at least one disorder compared to 36.8% of boys; AD: 49.3% vs. 13.2%; and MD: 27.3% vs. 5.6%.

Conclusion

Adolescents living in residential group homes of the Child Welfare System in France have notably high rates of mental disorder (about three times more than those of the general population of the same age), similar to the patterns found in adolescents in North America and Europe. These data are the first of their kind in France and will guide necessary changes to the child welfare system.     

Economic participation and national self-identification of refugees in the Netherlands

This study examines whether refugees self-identify as a member of the host society. We use survey data of more than 2,500 Somali, Iraqi, Afghani, Iranian, and ex-Yugoslavian refugees in the Netherlands. The results show that economic participation in the host country is positively related to refugees’ national self-identification. In addition, we find that refugees’ social ties with Dutch natives are associated with national self-identification and that the relationship between economic participation and national self-identification is partially explained by these social ties. Perceived discrimination is not related to refugees’ national self-identification. Implications of these findings for debates on immigration and integration are discussed.     

Neglect of older adults in Michigan nursing homes

Although research on domestic elder abuse and neglect has grown over the past 20 years, there is limited research on elder neglect in nursing homes. The purpose of this study is to estimate the incidence of elder neglect in nursing homes and identify the individual and contextual risks associated with elder neglect. Data came from a 2005 random digit dial survey of individuals in Michigan who had relatives in long term care. Our analytic sample included 414 family members who had a relative aged 65 or older in nursing homes. Results showed that about 21% of nursing home residents were neglected on one or more occasion in the last 12 months. Two nursing home residents' characteristics reported by family members appear to significantly increase the odds of neglect: functional impairments in activities of daily living and previous resident-to-resident victimization. Behavior problems also are associated with higher odds of neglect (p = 0.078). Policy implications of these results are discussed.

Stochastic Spanning

ABSTRACT

This study develops and implements methods for determining whether introducing new securities or relaxing investment constraints improves the investment opportunity set for all risk averse investors. We develop a test procedure for “stochastic spanning” for two nested portfolio sets based on subsampling and linear programming. The test is statistically consistent and asymptotically exact for a class of weakly dependent processes. A Monte Carlo simulation experiment shows good statistical size and power properties in finite samples of realistic dimensions. In an application to standard datasets of historical stock market returns, we accept market portfolio efficiency but reject two-fund separation, which suggests an important role for higher-order moment risk in portfolio theory and asset pricing.

The value of employment for people living with spinal cord injury in Norway

The purpose of this article is to examine the value of employment for people living with spinal cord injury in Norway. The main focus in the 31 interviews dealt with general perceptions of integration and participation. The value of employment was a major theme, primarily described by the participants in terms of personal and social identity in interaction with others, as a hegemonic social norm and a sense of moral obligation to contribute to society. The value of meaningful regular jobs – in contrast to government projects jobs or routine jobs – was emphasized.     

Beyond Transmission: Intergenerational Patterns of Family Formation Among Middle-Class American Families

Research about parental effects on family behavior focuses on intergenerational transmission: that is, whether children show the same family behavior as their parents. This focus potentially overemphasizes similarity and obscures heterogeneity in parental effects on family behavior. In this study, we make two contributions. First, instead of focusing on isolated focal events, we conceptualize parents’ and their children’s family formation holistically as the process of union formation and childbearing between ages 15 and 40. We then discuss mechanisms likely to shape these intergenerational patterns. Second, beyond estimating average transmission effects, we innovatively apply multichannel sequence analysis to dyadic sequence data on middle-class American families from the Longitudinal Study of Generations (LSOG; N = 461 parent-child dyads). The results show three salient intergenerational family formation patterns among this population: a strong transmission, a moderated transmission, and an intergenerational contrast pattern. We examine what determines parents’ and children’s likelihood to sort into a specific intergenerational pattern. For middle-class American families, educational upward mobility is a strong predictor of moderated intergenerational transmission, whereas close emotional bonds between parents and children foster strong intergenerational transmission. We conclude that intergenerational patterns of family formation are generated at the intersection of macro-structural change and family internal psychological dynamics.
