In human infants, the ability to share attention with others is facilitated by increases in attentional selectivity and focus. Differences in early attention have been associated with socio‐cognitive outcomes including language, yet the social mechanisms of attention organization in early infancy have only recently been considered. Here, we examined how social coordination between 5‐month‐old infants and caregivers relate to differences in infant attention, including looking preferences, span, and reactivity to caregivers’ social cues. Using a naturalistic play paradigm, we found that 5‐month‐olds who received a high ratio of sensitive (jointly focused) contingent responses showed strong preferences for objects with which their caregivers were manually engaged. In contrast, infants whose caregivers exhibited high ratios of redirection (attempts to shift focus) showed no preferences for caregivers’ held objects. Such differences have implications for recent models of cognitive development, which rely on early looking preferences for adults’ manually engaged objects as a pathway toward joint attention and word learning. Further, sensitivity and redirectiveness predicted infant attention even in reaction to caregiver responses that were non‐referential (neither sensitive nor redirective). In response to non‐referentials, infants of highly sensitive caregivers oriented less frequently than infants of highly redirective caregivers, who showed increased distractibility. Our results suggest that specific dyadic exchanges predict infant attention differences toward broader social cues, which may have consequences for social‐cognitive outcomes.  相似文献

This article uses data from the United Kingdom Medical Research Council Cognitive Function and Ageing study (MRC CFAS) to analyze morbidity associated with three areas of impairment. We use cognitive status, functional status, and physical illness to examine differences in the proportion of time that older women and men will spend with co-morbidity. We also analyze differences among various impairments, and investigate the relationship between missing data and sex. Women have a larger burden of impairment than men, and, by including cognitive impairment together with functional impairment, a very large impairment burden is highlighted at all ages. Policy implications of the findings from the perspective of older women in the United Kingdom are discussed.  相似文献

This paper assesses the reasons for the success or failure of manufacturing resource planning (MRPII) implementation projects. It begins by discussing the literature and research on success and failure of these systems and presents evidence from cases prepared by the authors. The paper is not concerned to prescribe ‘best practice’ for MRP implementation. The first section reviews the relevant literature and concludes that there is a divergence of opinion as to what constitutes success, raising questions on the usefulness of current methods of establishing whether implementation is successful. The latter section of the paper uses results from longitudinal (process) research carried out by the authors. This starts with a discussion of what counts for success. The discussion highlights the importance of understanding the full potential of MRPII in effecting change of organizational structures, cultures and practice. Several factors that contribute towards MRPII failure are next considered. Finally,‘big bang’style implementations, such as those recommended by the Ollie Wight organization, are most likely to be successful if the organization follows a strategic approach to planning. There also needs to be a high degree of fit between organizational structure, culture and the demands of the MRPII system.  相似文献

The face of the extended school in the United Kingdom is changing rapidly to facilitate the latest research and findings from experts, committees, and government advisory think tanks. This article highlights successful programs that use the voices of children and youth in planning for long-term success.  相似文献

The prevalence and ranking of non-timber forest products (NTFPs) as safety-nets has been well discussed, but rarely quantified. We report on group discussions and household interviews in two South African villages to assess the frequency and nature of shocks and stresses over a 2-year period and the coping strategies employed, stratified by household wealth and gender of the de jure household head. Overall, kinship was the most widely adopted coping strategy, and NTFPs were the fifth most prevalent (employed by 70% of households). There were relatively few differences in the nature of shocks or responses between male- and female-headed households. Wealth influenced the experience of shocks or stresses as well as responses. Poorer households have fewer options with the increased use or sale of NTFPs being the second most commonly adopted strategy. Increased use and sale of NTFPs is a common manifestation of the safety-net function. To reconcile long-term economic development and biodiversity conservation, it is important to understand people??s use of natural resources and the factors that affect this use, including their responses to shocks and stresses.  相似文献

During the COVID-19 pandemic, families have experienced unprecedented financial and social disruptions. We studied the impact of preexisting psychosocial factors and pandemic-related financial and social disruptions in relation to family well-being among N = 4091 adolescents and parents during early summer 2020, participating in the Adolescent Brain Cognitive DevelopmentSM Study. Poorer family well-being was linked to prepandemic psychosocial and financial adversity and was associated with pandemic-related material hardship and social disruptions to routines. Parental alcohol use increased risk for worsening of family relationships, while a greater endorsement of coping strategies was mainly associated with overall better family well-being. Financial and mental health support may be critical for family well-being during and after a widespread crisis, such as the COVID-19 pandemic.  相似文献

Children and young people in rural Australia experience disadvantage compared with metropolitan counterparts, with low educational attainment and disengagement from schooling being linked to poorer health outcomes. Schools are an existing contact point between individuals and health services. However, these health services are often overburdened and have limited scope to address broader social issues and teaching staff are focused on achieving curriculum outcomes. Embedding social workers within schools may provide an avenue for supporting students, yet social workers are rarely present in New South Wales public schools. This paper describes a study to determine teachers’ understanding of the socioeconomic issues faced by school students, and the role of the social work profession in addressing such issues as part of the early stages of establishing a Social Work in Schools (SWiS) project. Eighteen semistructured interviews were undertaken with teachers across four rural Australian schools. Participants identified their awareness of potential risk factors that could lead to educational disengagement, reflected on their own limitations in dealing with these broader health presentations given their teaching focus, and provided insights into their understanding of the potential role of social workers.  相似文献
