The present study investigated the effects of situational (child situational emotions) and dispositional (child temperament) child variables on mothers’ regulation of their own hostile (anger) and nonhostile (sadness and anxiety) emotions. Participants included 94 low and middle income mothers and their children (41 girls; 53 boys) aged 3 to 6 years. Children's situational emotions (anger, sadness, or fear) and parent emotion type (hostile or nonhostile) were important predictors of mothers’ regulation, but their effects were influenced by SES: Middle income mothers were more likely to control hostile than nonhostile emotions in response to child anger and sadness, and more likely than low income mothers to control hostile emotions in response to child sadness and fear. Low income mothers were more likely than middle income mothers to control nonhostile emotions in response to child anger. However, results also suggest that differences in emotion regulation between low and middle income mothers may stem from the link between SES and authoritarian parenting beliefs. Maternal regulation of negative emotion was not predicted by child temperament.  相似文献

As the public policy uses of U. S. census data have expanded in recent decades, census undercount has become a contentious public issue. Concern centers on the fact that persons that are economically and socially disadvantaged are omitted at higher rates than others. In this paper we outline some of the contributions which sociologists can make to the undercount debate. First, the uses of census data are reviewed, with emphasis on how coverage errors affect social science research. Next, a conceptual model of the census enumeration process is offered, and its social system and census process components are described.  相似文献

Drawing upon evidence collected during a study of female technical professionals in the electronics sector, this paper argues that organizational policies and practices in respect of this group continue to be underpinned by the ‘norm’ of the typical male employee whose family commitments impinge marginally, if at all, on work responsibilities. Women, as actual or potential mothers, continue to be seen as deviants from this norm, whose family commitments are likely to adversely affect work performance or commitment. Not only do these assumptions condition the general treatment of women technical professionals, but they are embodied in those policies and practices designed to facilitate the combination of motherhood and paid work. Both the assumptions around which policies are framed and their implementation in practice reinforce as unproblematic the prevailing domestic division of labour. Such policies and practices therefore continue to function essentially as a concession to the deviant status of women in general and mothers in particular, rather than as tools of a broader equal opportunities policy.  相似文献

How dominance in the competitive MovieViewer (MV) task relates to peer preference and assertive behavior, and whether these relations differ for boys and girls were explored. Ninety‐one preschool children in same‐sex quartets were videotaped interacting in the MV task and dominance ranks were assigned according to viewing time. Peer preference was explored by looking separately at the number of likes and dislikes a child received in sociometric interviews. Multivariate analyses revealed that sex interacted with rank to explain peer acceptance but not peer rejection. High ranked boys were accepted more by peers than low ranked boys, while low ranked girls were accepted more than high ranked girls. Further analyses revealed that girls, but not boys, accepted the low ranked girls. The difference in girls’ and boys’ acceptance of same‐sex peers who act assertively in the MV task is consistent with the notion that gendered cultures develop in the preschool years.  相似文献

Longitudinal data were analyzed for seminal characteristics of rhesus monkeys and beagles. The monkeys were exposed to DBCP; the beagles were exposed to acute or chronic whole body gamma irradiation. The semen was analyzed for volume and sperm concentration. Sperm were measured for percent motility, swimming speed, and head dimensions. Abnormalities of the sperm tail were also noted. All treatments resulted in measurable effects on the semen parameters. Sperm production, as evaluated by seminal sperm concentration or total sperm numbers in the ejaculate, was as informative of testicular toxicity as any other parameter or combination of parameters. A consistent finding was that changes in sperm output occurred concomitantly with changes in sperm motility.  相似文献

The dual purpose of this study was to identify the comprehensive health needs of a selected group of homeless children in Phoenix, Arizona, and to utilize the findings in developing needed services. A non-random sample of 60 infants and pre-school children were given on-site physical, dental, developmental, behavioral, and nutritional assessments. The study included Medicaid's Early Periodic Screening, Diagnosis, and Treatment procedures, complete oral screening, the Denver Developmental and Denver Articulation Screening Test, the Pre-school Behavior Inventory, and parental interviews. Fifty-eight of the 60 children screened needed further evaluation, treatment, or followup services. The most significant problems included low hematocrit readings, inadequate immunizations, and untreated medical and dental problems specific to this age group. Also identified were developmental delays and potential behavior problems. It is imperative that aggressive outreach and followup services be developed to reach homeless children and to insure that needed interventions are provided.  相似文献

We discuss a general approach to dynamic sparsity modeling in multivariate time series analysis. Time-varying parameters are linked to latent processes that are thresholded to induce zero values adaptively, providing natural mechanisms for dynamic variable inclusion/selection. We discuss Bayesian model specification, analysis and prediction in dynamic regressions, time-varying vector autoregressions, and multivariate volatility models using latent thresholding. Application to a topical macroeconomic time series problem illustrates some of the benefits of the approach in terms of statistical and economic interpretations as well as improved predictions. Supplementary materials for this article are available online.  相似文献

For this issue of “From Picas to Pixels,” incoming co-editor Jessamyn West talks to fellow rogue librarian Jenna Freedman, curator of the Barnard Zine Collection. Are zines serials or monographs? Should they circulate or not? Jenna and Jessamyn discuss the difficulties of getting a zine collection started, the difficulties of keeping them alive, and much more.  相似文献
