The influence of socioeconomic variability on language and cognitive development is present from toddlerhood to adolescence and calls for investigating its earliest manifestation. Response to joint attention (RJA) abilities constitute a foundational developmental milestone that are associated with future language, cognitive, and social skills. How aspects of the family home environment shape RJA skills is relatively unknown. We investigated associations between family socioeconomic status (SES) —both parent education and family percentage of the federal poverty level (FPL)— parent depressive and anxiety symptoms and infant RJA performance in a cross-sectional sample of 173 infants aged 8–18 months and their parents from a variety of socioeconomic backgrounds. Results suggest that, correcting for age and receptive language, infants in families with greater economic resources respond to relatively less redundant, more sophisticated cues for joint attention. Although parent depressive and anxiety symptoms are negatively correlated with SES, parent depressive and anxiety symptoms were not associated with infant RJA. These findings provide evidence of SES-related differences in social cognitive development as early as infancy, calling on policymakers to address the inequities in the current socioeconomic landscape of the United States.  相似文献

Abstract

Female assembly workers reporting constant neck and shoulder pain, despite ergonomically acceptable working conditions, were interviewed. As a starting point in the interviews, the patients were asked to describe their general situation at work. Their reports were fed back and discussed with company management in a wider group meeting and resulted in an improvement in their attitudes to those workers. A climate of confidence and well-being was created, which the women experienced as genuine. The workers' report of pains improved dramatically and absence due to musculoskeletal disorders was reduced by more than 90% during the following year.  相似文献

Problem gambling is heterogeneous in nature, ranging in severity from occasional but problematic gambling episodes, to extreme, impulsive and pervasive gambling behaviour. Problem gambling may be accompanied by a sense of impaired control and can give rise to financial, interpersonal, legal and vocational costs for the sufferer, their families and society. This study investigated the relationship among metacognitions, anxiety, depression and gambling in a sample of problem gamblers. A total of 91 individuals attending gambling treatment services completed a battery of self-report instruments that consisted of the Metacognitions Questionnaire 30 (MCQ-30), the Hospital Anxiety and Depression Scale (HADS) and the South Oaks Gambling Scale (SOGS). Correlation analyses showed that anxiety, depression and metacognitions were positively and significantly correlated with both gambling consequences and behaviour. Hierarchical regression analyses indicated that two metacognitive constructs (negative beliefs about thoughts concerning uncontrollability and danger and beliefs about the need to control thoughts) predicted gambling behaviour independently of anxiety and depression. These findings are consistent with the hypothesis that metacognitions play a role in problem gambling.  相似文献

Through a comparative historical study of community pharmacy in the UK, Italy, Sweden and the USA, the authors examine what happens to institutional arrangements designed to resolve ongoing conflicts between institutional logics over extended periods of time. It is found that institutional arrangements can reflect the heterogeneity of multiple logics without resulting in hybridization or dominance. Because logics remain active, similar conflicts can reappear multiple times. It is found that the durability of the configurations of competing logics reflects the characteristics of the polities in which fields are embedded. The dominance of any societal institutional order leads to more stable field‐level arrangements. The authors suggest that the metaphor of institutional knots and the related image of institutional knotting are useful to capture aspects of this dynamic and to foreground the discursive and material work that allows multiple logics to coexist in local arrangements with variable durability.  相似文献

In this study, a changepoint model, which can detect either a mean shift or a trend change when accounting for autocorrelation in short time-series, was investigated with simulations and a new method is proposed. The changepoint hypotheses were tested using a likelihood ratio test. The test statistic does not follow a known distribution and depends on the length of the time-series and the autocorrelation. The results imply that it is not possible to detect autocorrelation and that the estimate of the autocorrelation parameter is biased. It is therefore recommended to use critical values from the empirical distribution for a fixed autocorrelation.  相似文献

Membership in voluntary associations is often assumed to have a homogenizing or diversifying impact on the social composition of members' personal relations. In this study, we examine these assertions empirically in a sample (n = 818) comprising active members of voluntary associations in a typical midsized Swedish community. We investigate whether people whom active members of voluntary associations have met through their voluntary activities are more or less likely to share their social characteristics than people whom they have met elsewhere. Our results show that acquaintances whom our respondents have acquired within voluntary associations are less likely to share several of their significant social characteristics than other members of their personal networks, but more likely to reside in their vicinity than others. Consequently, our results give fairly robust support to the “integrating hypothesis” according to which voluntary associations contribute to the social diversification of their members' personal networks. We do, however, emphasize the principally important aspects of our results, according to which relations acquired through involvement in voluntary associations may have simultaneously homogenizing and diversifying effects on individuals' personal networks. Furthermore, the effect may also depend on the specific dimension(s) of the networks under consideration.  相似文献

Patterns of nonsuicidal self‐injury (NSSI) and their association with other psychological difficulties were studied in a community sample of young Swedish adolescents, by a two‐wave longitudinal design with a 1‐year interval. Hierarchical cluster analysis at T1 identified eight NSSI subgroups in each gender, of which five were clearly replicated at T2. Among these were a subgroup with generalized high‐frequency NSSI, which was associated with both internalizing and externalizing problems, and a subgroup of girls who engaged primarily in cutting and showed mainly internalizing problems. In general, NSSI clusters among girls were more stable over time and associated with more psychological problems. The results indicate that different patterns of NSSI have different developmental and clinical implications.  相似文献

The purpose of this paper is to introduce a system of annual indices of the risks of marriage and remarriage and to use the system to display such marriage risks for Swedish women over the years since 1971. Our indices are produced by applying indirect standardization to register data. The propensity to marry decreased considerably during the 1970s and it has continued to decrease also during the first half of the 1980s and the beginning of the 1990s. The decrease in marriage risks is mostly due to a decreased propensity to marry among never-married women with no children. The decrease is not so strong for never-married women with children and for divorced women. A sharp, but only temporary, deviation from the general pattern of Swedish marriage-risk trends occurred in 1989, when the number of marriages formed increased dramatically in response to the near-abolition of the public widow's pensions for women who were not married at the beginning of 1990.  相似文献
