Protective behavioral strategies (PBS) are useful skills for reducing the negative consequences of alcohol. The moderating effects of anxiety on the relationship between 3 different types of PBS and negative consequences were examined among students accessing college counseling services. Results revealed a significant interaction between anxiety and strategies while drinking, suggesting that these simple strategies may be particularly beneficial among students who drink heavily and experience high levels of anxiety. Implications for counseling centers are discussed. 相似文献

In this paper, we report on an investigation into sustainability education in schools in the Australian state of Tasmania following the implementation of the Australian Curriculum. Sustainability is one of three cross-curriculum priorities in the new national curriculum and is the focus of this research (sustainability cross-curriculum priority (CCP)). Principals and Curriculum Leaders (PCLs) from all schools in Tasmania were invited to complete a survey that asked them about their understanding of various aspects of sustainability and how the sustainability CCP was integrated across learning areas. Sixty-eight PCLs (24%) responded to the survey. They reported generally good understandings of sustainability and education for sustainability, but lesser understandings of the sustainability CCP and the nine organising ideas. Respondents’ understandings of sustainability were dominated by an environmental focus. The PCLs’ responses in relation to sustainability implementation across learning areas gave insights into ways that the sustainability CCP can serve as a pivot for cross-curricular teaching and learning, which is strongly advocated for achieving transformative sustainability education. We conclude this paper with a discussion of how the sustainability CCP is an important asset in the necessary reorientation of the Australian formal education system for a more sustainable future. We note the importance of professional support so that educators may better understand sustainability and its complexity as a cross-curricular priority and envision ways in which the sustainability CCP can be realised within education. 相似文献

Environmental education can deliver benefits to individuals, society and the environment, but few studies have asked practitioners or participants what they feel these benefits are. This research compares the perspectives of practitioners and participants in environmental education projects, using questionnaires, focus groups and participant observation. Practitioners and participants listed a large number of outcomes, with increasing knowledge about the environment mentioned most frequently. For participants, this was often in relation to gaining new skills. Social outcomes, such as making new friends, were more prominent in participant than practitioner responses. Practitioners did not spontaneously mention any negative outcomes of environmental education, and few were suggested with prompting. Participants suggested more negative outcomes than practitioners, notably damage to the environment. The differing views suggest a need for greater discussion between practitioners and their participants. 相似文献

During the 18th century, the reinvention of French surgery as a ‘monarchical profession’, in the words of Toby Gelfand, enabled the creation of an elite surgical knowledge from which uninstructed participants could be excluded. A link can be made between the types of resources used by surgeons to present themselves as expert healers, and the epistemological strategies of the operation. The sickbed was the scene of a performance, in which every actor's movements were described and constrained; the end product of an extended process of social negotiation, surgical training, physical restraint and submission. 相似文献

The hypothesis was tested that some children develop a defensive mindset that subsumes individual social information processing (SIP) steps, grows from early experiences, and guides long-term outcomes. In Study 1 (Fast Track [FT]), 463 age-5 children (45% girls; 43% Black) were first assessed in 1991 and followed through age 32 (83% retention). In Study 2 (Child Development Project [CDP]), 585 age-5 children (48% girls, 17% Black) were first assessed in 1987 and followed through age 34 (78% retention). In both studies, measures were collected of early adverse experiences, defensive mindset and SIP, and adult outcomes. Across both studies, a robust latent construct of school-age defensive mindset was validated empirically (comparative fit index = .99 in each study) and found to mediate the impact of early child abuse (38% in FT and 29% in CDP of total effect) and peer social rejection (14% in FT and 7% in CDP of total effect) on adult incarceration. 相似文献

This study used secondary data from the My Teaching Partner-Math/Science 2013–2016 randomized control trial to explore whether equitable sociocultural classroom interactions (see Curenton et al., 2019) were associated with the skills of 105 four- and five-year-olds (52% boys; drawn from 20 unique video recordings of preschool teachers/classrooms; 43% were Black, Latine, Asian, or other racially marginalized learners). Equitable interactions predicted children's skills with effect sizes ranging from small (0.01–0.44) to large (1.00). Moderation analyses revealed that when classrooms had more racially marginalized learners, teachers’ use of equitable disciplinary and personalized learning practices were associated with higher executive functioning gains across prekindergarten. Findings illustrate how classroom composition can be a key indicator between equitable classroom interactions and young children's early skills. 相似文献

Intellectual performance is highly heritable and robustly predicts lifelong health and success but the earliest manifestations of genetic effects on this asset are not well understood. This study examined whether early executive function (EF) or verbal performance mediate genetic influences on subsequent intellectual performance, in 561 U.S.-based adoptees (57% male) and their birth and adoptive parents (70% and 92% White, 13% and 4% African American, 7% and 2% Latinx, respectively), administered measures in 2003–2017. Genetic influences on children's academic performance at 7 years were mediated by verbal performance at 4.5 years (β = .22, 95% CI [0.08, 0.35], p = .002) and not via EF, indicating that verbal performance is an early manifestation of genetic propensity for intellectual performance. 相似文献

Developmental theories often assume that specific environmental risks affect specific outcomes. Canonical Correlation Analysis was used to test whether 28 developmental outcomes (measured at 11–15 years) share the same early environmental risk factors (measured at 0–3 years), or whether specific outcomes are associated with specific risks. We used data from the UK Millennium Cohort Study (N = 10,376, 51% Female, 84% White) collected between 2001 and 2016. A single environment component was mostly sufficient for explaining cognition and parent-rated behavior outcomes. In contrast, adolescents’ alcohol and tobacco use were specifically associated with their parents’, and child-rated mental health was weakly associated with all risks. These findings suggest that with some exceptions, many different developmental outcomes share the same early environmental risk factors. 相似文献
