Laudato si' attempts simultaneously to disrupt prevailing global environmental discourse and to reorient central concepts in Catholic moral tradition by requalifying the meaning of dominion and by ecologically expanding human dignity. The image of Earth crying out to humans from within a kinship relation plays a central role in both arguments. However, the political consequences of those shifts remain vague because the “voice” of Earth remains silent in crucial loci of the encyclical's argument.  相似文献

In a socio‐demographically diverse sample of 501 caregivers participating in a longitudinal birth cohort study during the childbearing years, we examined whether neighborhood collective efficacy moderated the association between maternal adverse childhood experience (ACEs) and marital conflict. Maternal ACEs were assessed via retrospective reports. Neighborhood collective efficacy was measured via maternal and paternal reports at 2 months, and maternal reports of marital conflict were collected at infant age 2 and 18 months. Multiple linear regression analyses revealed that maternal ACEs were associated with increased marital conflict. Neighborhood collective efficacy moderated the association between early maternal ACEs and marital conflict, such that mothers experiencing ACEs had lower levels of marital conflict when exposed to high levels of neighborhood collective efficacy. Results suggest that extra‐familial sources of social support and control, such as feelings of security, trust, order, and connectedness with others, may buffer the effects of early adversity on marital discord.  相似文献

Research in face recognition has tended to focus on discriminating between individuals, or “telling people apart.” It has recently become clear that it is also necessary to understand how images of the same person can vary, or “telling people together.” Learning a new face, and tracking its representation as it changes from unfamiliar to familiar, involves an abstraction of the variability in different images of that person's face. Here, we present an application of principal components analysis computed across different photos of the same person. We demonstrate that people vary in systematic ways, and that this variability is idiosyncratic—the dimensions of variability in one face do not generalize well to another. Learning a new face therefore entails learning how that face varies. We present evidence for this proposal and suggest that it provides an explanation for various effects in face recognition. We conclude by making a number of testable predictions derived from this framework.  相似文献

The authors conducted a content analysis on the type, frequency, and intensity of use of various indicators of rigor for 68 qualitative research articles published between 1999 and 2014 in the Journal of Counseling & Development. The authors identified the most frequently listed and implemented strategies for the research articles. The authors found a significant engagement in rigor strategies across time, variations in intensity in strategy use, and a significant positive relationship between intensity of strategy use across time.  相似文献

The current longitudinal study examined the role of cumulative social risk on children's theory of mind (ToM) and executive functioning (EF) across early development. Further, we also tested a cascade model of development in which children's social cognition at 18 months was hypothesized to predict ToM and EF at age 4.5 through intermediary language skills at age 3. We then examined whether this developmental mechanism varied as a function of social risk status. Participants were 501 children recruited when they were newborns, at which point eight psychosocial risk factors were assessed and combined into a metric of cumulative social disadvantage. Families were followed up at 18 months, at which point four social‐cognitive skills were assessed using developmentally sensitive tasks: joint attention, empathy, cooperation, and self‐recognition. Language was measured at age 3 using a standardized measure of receptive vocabulary. At age 3 and 4.5, EF and ToM were measured using previously validated tasks. Results showed that there were notable cumulative risk disparities in overall neurocognitive skill development, and these effects became more differentiated over time. Support was also found for a developmental mechanism wherein the effect of social cognition at 18 months on ToM and EF in the preschool period operated specifically through children's receptive language ability at age 3. This pathway functioned similarly for children with both low‐ and high‐risk backgrounds. These results extend previous findings by documenting the role of cumulative social disadvantage on children's neurocognition and the pathways that link key neurocognitive abilities across early development.  相似文献

Clostridioides difficile spores were previously demonstrated to survive industrial laundering. Understanding interactions between heat, disinfectants and soiling (e.g. bodily fluids) affecting C. difficile spore survival could inform the optimization of healthcare laundry processes. Reducing spore attachment to linen could also enhance laundering efficacy. This study aimed to compare the sensitivity of C. difficile spores to heat and detergent, with and without soiling and to investigate adherence to cotton. Survival of C. difficile spores exposed to industrial laundering temperatures (71–90°C), reference detergent and industrial detergent was quantified with and without soiling. The adherence to cotton after 0 and 24 h air drying was determined with the exosporium of C. difficile spores partially or fully removed. Clostridioides difficile spores were stable at 71°C for 20 min (≤0·37 log10 reduction) while 90°C was sporicidal (3 log10 reduction); soiling exerted a protective effect. Industrial detergent was more effective at 71°C compared to 25°C (2·81 vs 0·84 log10 reductions), however, specifications for sporicidal activity (>3 log10 reduction) were not met. Clostridioides difficile spores increasingly adhered to cotton over time, with 49% adherence after 24 h. Removal of the exosporium increased adherence by 19–23% compared to untreated spores. Further understanding of the role of the exosporium in attachment to cotton could enhance spore removal and aid decontamination of linen.  相似文献

This special section addresses a gap area of resilience and LGBT well‐being. Although comprehensive global diversity regarding LGBT resilience was challenging to find, the special section includes representation from outside the US (Israel and Hong Kong), ethnic/racially diverse domestic populations, immigration, and one population for which LGBT identities might be considered marginalized—Christians in the US. The full range of LGBT identities are represented in the issue along with persons identifying as queer or questioning, although transgendered people were less well represented than lesbian, gay or bisexual identities.  相似文献
