Technology is pervasive in homes of families with young children, despite evidence for negative associations between infant exposure to screen‐based media and cognitive development that has led the American Academy of Pediatrics (AAP) to discourage parents from exposing children under the age of 18 months to any kind of screen time (AAP, 2016). Here, we apply a propensity score matching approach to estimate relations between electronic screen‐based media use in infancy and executive function in early toddlerhood. In an international sample of 416 firstborn infants, parental report of regular exposure to screen‐based media at 4 months predicted poorer performance on a test of inhibition at 14 months, but was unrelated to either cognitive flexibility or working memory at 14 months. Results of this study are therefore consistent with the view that early exposure to screen‐based media adversely affects the development of executive function. 相似文献

Understanding why socially marginalized individuals, such as lesbian, gay, bisexual, transgender and/or queer (LGBTQ+) people, participate in research can improve qualitative research designs, as well as social services and policies. In providing a participant-centered foundation, we interviewed 65 LGBTQ+ young adults and asked “Why are certain LGBTQ+ young adults motivated to engage in qualitative social science studies?” Many LGBTQ+ young people said they were committed to enacting social change and promoting advocacy. Participants also highlighted supporting scientific research and knowledge production. Finally, LGBTQ?+ participants engaged with research to introspectively analyze their identity development processes. These findings can facilitate access to socially vulnerable and underrepresented groups through a methodological focus on participant benefits. 相似文献

This study examined the parallel mediational processes between sensation seeking and parental rules on alcohol, in the emergence of heavy episodic drinking (HED) in adolescents. Data were drawn from a U.K. clustered randomized control trial (control arm only, N ≈ 6,300, Mage at baseline = 12.5). Using parallel process latent growth curve analysis, stricter parental rules at baseline were found to be associated with greater declines in sensation seeking over time and a lower risk of HED at follow‐up (+33 months). Higher initial levels of sensation seeking predicted a faster relaxation of parental rules and a greater risk of HED. By maintaining strict rules about alcohol, parents may promote a positive reduction in sensation seeking and a lower risk of HED. 相似文献

Many studies have sought to gauge the impact of population growth on economic growth. A well‐known stylized fact of this literature is that the estimated effects of population growth measures on economic growth are not robust, varying between being positive, negative, and insignificantly different from zero. The present study analyzes 471 statistical regressions from 29 prominent economic growth studies using meta‐regression analysis to identify the effect of alternative methodologies on key population growth results. This study finds that a broad set of methodological factors explains more than half of the variation in the population growth effects observed from this literature, including the types of variables used to measure population growth, the countries selected, the time frame of the analysis, and the nature of the control variables specified. The study also yields results that have implications for policymakers, especially insofar as several policy factors seem to influence the population change–economic growth nexus. Particularly strong is the evidence in support of the increasingly adverse effects of population growth in the post‐1980 period, suggesting that demographic issues should warrant greater attention than they currently receive from the policymaking community. 相似文献

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing
and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood.
We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories
during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood
that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen
motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood.
This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers
of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further
and thus reduce the need for welfare support and child support enforcement in the long run.

Various approaches to personalisation are well-established in the UK social care sector and are now starting to ‘travel’ to other sectors. In this paper we report findings from an evaluation of a pilot to test elements of personalisation in the management of offenders in probation services within the English criminal justice system. Following a review of evidence from social care, three different approaches to personalised-practice were developed and tested on a small-scale in three separate sites. The evaluation finds that all three approaches were implemented reasonably successfully, but challenges were identified including that personalised approaches are more time-consuming, that staff need support to exercise professional discretion and that balancing greater choice with managing criminogenic risk requires new ways of conceptualising the relationship between case manager and service user. Overall, ‘deeper’ approaches to personalisation, such as co-production, will take time to emerge. This paper makes two important contributions to the debate on personalisation in public services. First, it addresses the question of how transferable the concept of personalisation is from the social care sector to other sectors in the UK, in this case the criminal justice system. Secondly, it outlines a methodology for developing and evaluating personalisation pilots, prior to a wider roll-out. 相似文献

Undergraduate career planning courses have shown efficacy in decreasing students’ negative career thoughts; however, universities have minimally applied these courses to science, technology, engineering, and math (STEM) populations. This study compared the influence of a STEM‐focused career planning course for undecided STEM students with a seminar course for decided STEM majors. An analysis of covariance with covariate adjustment revealed that undecided career planning students had lower adjusted mean scores on a measure of negative career thinking than the decided STEM majors after the first semester of college. The results provide support for the efficacy of STEM‐focused career planning courses and measuring negative career thoughts with STEM undergraduates. 相似文献

The image of engineering as a masculine profession has reproduced the perception that engineering is unsuitable for women. While various strategies have been used to try to increase the number of women entering engineering education and employment, their success has been limited. At the same time it has been argued that the way gender is ‘done’ in work can help diminish or increase inequality between the sexes. Using empirical research exploring women engineering students’ workplace experiences, this article considers how gender performance explains their behaviour and attitudes. Butler implied that doing gender can result in our being ‘undone’. This was specifically found to be the case for the women students in this study, who performed their gender in a particular way in order to gain male acceptance. In doing this they utilized certain coping strategies: acting like one of the boys, accepting gender discrimination, achieving a reputation, seeing the advantages over the disadvantages and adopting an ‘anti‐woman’ approach. These strategies are part of women's enculturation and professionalization in engineering, yet they also fail to value femaleness. In ‘doing’ engineering, women often ‘undo’ their gender. Such gender performance does nothing to challenge the gendered culture of engineering, and in many ways contributes to maintaining an environment that is hostile to women. 相似文献

Objective: Compulsivity has been associated with use of dopamine agonists used to treat Parkinson’s disease (PD). Increasing use of
these agents to treat fibromyalgia (FM) raises concern for this unexpected toxicity in a new group of patients. This is the
first report of compulsive gambling and shopping among patients taking dopamine agonists for treatment of FM. Design: A retrospective chart review of all patients in a large, active FM research practice was used to identify compulsivity associated
with dopamine agonists and describe its remission following dug withdrawal. Results: Of 3006 patients with FM treated between 2002 and 2006, 1356 had taken ≥1 dose of a dopamine agonist ( >95% pramipexole).
Twenty-one (3 male, 18 female) were identified with compulsive gambling (33%), shopping (40%) or both (27%) after taking a
4.5 mg mean dose of pramipexole at bedtime for 14.4 ± 14.9 months. Compulsivity resolved in 3–10 days for 19 of 21 patients
and by 3 months for all following a monitored, compulsory tapered discontinuation over 7 days. Conclusions: While biologic aspects of PD and FM differ considerably, compulsive gambling and shopping have become important, yet unexpected
concerns related to use of dopamine agonists for patients with FM and their treating clinicians. 相似文献

The present paper develops and tests two temporal models of the relationships among adolescents' ethnic identity exploration, ethnic identity affirmation and belonging, and attitudes toward their racial/ethnic ingroup and outgroups. Structural equation models for Euro‐Americans, Asian Americans, and Latinos revealed that all hypothesized relationships were positive and significant. The model in which ethnic identity exploration (at Time 1) predicts ethnic identity affirmation and belonging (at Time 2) was superior to the alternative model in which the relationship between them was reversed (i.e., affirmation and belonging at Time 1 predicts exploration at Time 2). Results (1) support the importance of exploration as a basis for establishing a secure attachment to one's ethnic identity, which, in turn, has positive implications for attitudes toward one's own group and other groups and (2) suggest that maintenance of ethnic identity is compatible with positive attitudes toward ethnic outgroups. 相似文献
