Utilizing multiple measures of interpretive biases, the current study examined the roles of toddlers’ behavioral inhibition (BI) and maternal supportive reactions to children's negative emotions in relation to children's interpretive biases across middle to late childhood. Toddlers’ BI was measured during several laboratory tasks (n = 248) at 2 and 3 years of age. Mothers reported on their reactions to children's negative emotional expressions when children were 7 years old (n = 203), and children's interpretations of social cues were assessed at 7 and 10 years of age (n s = 179 and 161, respectively). Toddlers with high levels of BI expressed less positivity toward social engagement with unfamiliar peers during discussion of ambiguous social situations. Further, children with high BI were less likely to attribute the cause of negative social situations to external factors, particularly when mothers were less accepting of children's negative emotional displays. Findings are discussed in terms of cognition related to the interpretation of ambiguous and threat‐related social situations among temperamentally at‐risk children.  相似文献

Adolescents’ defending of peers who are being bullied—or peer defending—was recently found to be a heterogeneous behavioral construct. The present study investigated individual differences in adolescents’ motivations for executing these indirect, direct, and hybrid defending behaviors. In line with the literature on bullying as goal‐directed strategic behavior, we adopted a social evolution theory framework to investigate whether these peer‐defending behaviors could qualify as goal‐directed strategic prosocial behaviors. A sample of 549 Dutch adolescents (49.4% boys; Mage = 12.5 years, SD = 0.6 years) participated in this study. Their peer reported defending behaviors (including bullying behavior as a control variable) and the following behavioral motivations were assessed: (a) agentic and communal goals (self‐report), (b) prosocial and coercive social strategies (peer report), and (c) altruistic and egocentric motivations for prosocial behavior (self‐report). The outcomes of hierarchical linear regression analyses suggest that adolescents’ motivations for executing the different subtypes of peer defending partially overlap but are also different. While indirect defending was fostered by genuine concerns for victims’ well‐being, direct defending was more motivated by personal gains. Hybrid defending combined favorable aspects of both indirect and direct defending as a goal‐directed, strategic, and altruistically motivated prosocial behavior. The implications of these findings are discussed.  相似文献

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data.  相似文献

Using a real-world data set encompassing the daily portfolio holdings and exposures of complex investment funds, we derive a set of quantitative attributes to capture essential behavioral features of fund managers. We find the existence and stability of three investment attitudes, namely the conservative, the reactive, and the pro-active profiles, defining communities that respond differently when facing external shocks. The conservative community has behavioral similarities that tend to decrease due to external shocks, the reactive community members greatly increase their activity level especially during turmoil phases, while delegated investors in the pro-active community are more resilient to turbulence and counterbalance the impact of the events by adjusting their portfolio exposures in advance. We show that exogenous shocks only temporarily perturb the behavioral traits of the communities which then go back to their original states once the distress is embedded.  相似文献

Ethiopia has been lauded for its economic growth and progress in human development indicators. For some, that success is rooted in the developmental state approach advocated by the government. For others, the theory of the developmental state and the practice in Ethiopia were often at odds. Up until 2018, ideas that challenged the state and its approaches were not welcome, and politicians, academics and journalists were jailed for expressing alternative views. However, this appears to have changed, and in June 2018 the Deputy Prime Minister called for debate on the developmental state model. This article explores Ethiopia's developmental state model using the building stability framework, analysing its ability to establish fair power structures, foster inclusive economic growth, develop conflict‐resolution mechanisms, create effective and legitimate institutions, and enable a supportive regional environment. We find the developmental state was effective in a number of ways, but that this modality of governance appears to have passed its peak of securing advantage in Ethiopia. A shift from the developmental state to developmental democracy appears to be underway. Decision‐making and economic policies need to align with this change.  相似文献

This paper proposes a community-building framework as an innovative strategy to begin to re-claim children and families at risk. It is a strategy that identifies a purpose, a value base, knowledge and theoretical dimensions, and methods of practice that present as an approach for child welfare systems to consider shifts in thinking in order to meet what is considered the most important challenge of the next century: that of rediscovering community.

ABSTRACT

There are growing numbers of Adult Day Health Care (ADHC) programs providing needed health services to community-dwelling elderly. Therefore, ADHC staff are in an opportune position to identify and to intervene in suspected elder mistreatment (EM) cases. In this paper, prevalence estimates of EM are reported for a probability sample of ADHC clients in New York State, using data provided during a social worker informant interview. The abuse “signs and symptoms” items in the social worker informant interview schedule were divided into two categories: (1) physical indicators and (2) client's behavioral indicators. Physical indicators included unexplained bruises and welts, unexplained burns, unexplained lacerations or abrasions, human bite marks, and frequent injuries that are “accidental” or “unexplained.” Client's behavioral indicators included apprehension, being frightened, and afraid to go home. EM prevalence for all 8 items was 12.3 percent. When “apprehensive” was excluded, the EM prevalence was 3.6 percent in this sample. These findings suggest that ADHC provides a point of contact for the assessment and intervention of EM that might otherwise be overlooked among elders who are often isolated or homebound.  相似文献

论民族视角的经济研究   总被引:4,自引:0,他引:4  
本文提出把民族作为中国少数民族经济或民族经济学的分析框架。民族生存的自然环境和民族认同的文化特质构成民族概念的内在规定,并呈现为民族经济生活自然差异和文化差异二重性。把握民族经济生活差异二重性是建构学科理论框架的关键。  相似文献
