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

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

In a time of unprecedented polarization in the United States, particularly concerning immigration, schools are uniquely positioned to help students understand the consequences of drastic policy changes. Beyond formal settings such as social studies classes, extracurricular activities may be important for fostering discussions about sociohistorical and policy issues. Such discussions could serve to empower youth from marginalized populations and raise their critical consciousness. Yet the potential outcomes of discussions in these extracurricular settings have not been studied in depth. Using data collected in school-based Gender-and-Sexuality-Alliances (GSAs) throughout Massachusetts during the periods leading up to and following the 2016 US Presidential election, we examined whether discussions of immigration issues in GSAs were associated with greater empowerment and critical consciousness among 580 youth (M Age = 15.59, range = 10–20 years). Multilevel structural equation models showed that the frequency with which youth discussed immigration, relative to their fellow members, was positively associated with residualized change in perceived peer validation for members in general and with residualized change in hope for immigrant-origin members only. Contrary to our expectations, we did not find significant associations for critical consciousness. Findings suggest how groups addressing issues of equity and justice can promote members' empowerment. 相似文献

This meta-analysis examined the relationship between prenatal maternal stress and/or anxiety and the outcomes of children aged 3 months to 9 years. Of the 8754 studies published before June 2021 that were synthesized, 17 conducted in Western countries were included in the meta-analysis (Ntotal = 23,307; Mmales 54%; Methnicity White 77%, Pacific 15%, African American/Black 10%, Middle Eastern 7%, Eastern 8%). Effect sizes ranged from −0.41 to 0.15. A weak negative association was found between prenatal stress and/or anxiety exposure and children's general intellectual development. Associations varied based on the type of exposure. Findings are limited to developed counties and cannot be generalized to low- and middle-income countries. Directions for maternal prenatal intervention and future studies are discussed. 相似文献

Infant social–emotional development may be impacted by the COVID-19 pandemic. This study investigated associations between maternal pre- and postnatal pandemic-related concerns and social–emotional developmental risk. Data, collected in 2020–2021, came from 220 mothers (87% white, 6% Hispanic, 1% Black, 3% Asian, 1% American Indian, Mage = 32.46 years), and infants (53.18% male, Mage = 12.98 months) in the United States. Maternal postnatal pandemic-related concerns were associated with total risk scores (B = 6.09, p-value <.001) and offspring risk of scoring positive for problems related to inflexibility (B = 4.07, p-value = .006). The total score association was moderated by self-reported social support. Infants may be detrimentally impacted by the pandemic via maternal pandemic-related concerns. Maternal social support may buffer infants. 相似文献
