A lack of adequate childcare can delay mothers’ return to the labor market after childbirth. This paper examines whether social support with childcare by kin and friends facilitates maternal employment in the first 72 months after childbirth. Using data from the German Socio-Economic Panel (SOEP) 1993–2009, a comparison of natives (n?=?1409) and migrants (n?=?411) in corporative-conservative western Germany with mothers in former socialist eastern Germany (n?=?528) shows that kinship support is positively associated with maternal employment when public childcare is limited. Western German and migrant mothers return to work sooner if they are surrounded by kin. But kin do not provide support for maternal employment in eastern Germany, where public childcare is more easily accessible and continuous female employment is a prevalent social norm. Friendship networks, by contrast, are most valuable for maternal employment if they complement public childcare. 相似文献

This article explains Internet users’ self-help activities in protecting their privacy online using structural equation modeling. Based on a representative survey of Swiss Internet users, it reveals past experiences with privacy breaches as a strong predictor of current protective behavior. Further, in line with the ‘privacy paradox’ argument, caring about privacy (privacy attitudes) alone does not necessarily result in substantial self-protection. Most strikingly, however, general Internet skills are key in explaining users’ privacy behavior. These skills enable users to reduce risks of privacy loss while obtaining the benefits from online activities that increasingly depend on the revelation of personal data. Consequently, Internet skills are an essential starting point for public policies regarding users’ self-help in privacy protection. 相似文献

ABSTRACTApplying primary socialization theory to a sample of early adolescents from Nicaragua, this study examines direct and indirect associations between family bonding and adolescent alcohol use via substance specific prevention communication (SSPC) and adolescent efficacy. Early adolescents in 7th and 8th grades completed a self-report, cross-sectional survey. Structural equation modeling revealed that family expressiveness was significantly indirectly related to adolescent lifetime alcohol use through SSPC. Results are discussed in relation to primary socialization theory, family communication, and international substance use prevention efforts. This study provides supportive evidence for the important role of positive family communication as a protective factor for early adolescents in Nicaragua. 相似文献

Using the eye gaze of others to direct one's own attention develops during the first year of life and is thought to be an important skill for learning and social communication. However, it is currently unclear whether infants differentially attend to and encode objects cued by the eye gaze of individuals within familiar groups (e.g., own race, more familiar sex) relative to unfamiliar groups (e.g., other race, less familiar sex). During gaze cueing, but prior to the presentation of objects, 10‐month‐olds looked longer to the eyes of own‐race faces relative to 5‐month‐olds and relative to the eyes of other‐race faces. After gaze cueing, two objects were presented alongside the face and at both ages, infants looked longer to the uncued objects for faces from the more familiar‐sex and longer to cued objects for the less familiar‐sex faces. Finally, during the test phase, both 5‐ and 10‐month‐old infants looked longer to uncued objects relative to cued objects but only when the objects were cued by an own‐race and familiar‐sex individual. Results demonstrate that infants use face eye gaze differently when the cue comes from someone within a highly experienced group. 相似文献

Factitious Disorder Imposed by Another (FDIA) can be difficult to expeditiously identify. Understanding personality characteristics of FDIA perpetrators via psychological assessment may decrease the time between initial abuse and identification of FDIA. Personality characteristics of FDIA mother-perpetrators were examined through a comparative analysis of MMPI-2 profiles. It was predicted that mother-perpetrators would have significantly higher overall profile elevations on the MMPI-2 and elevations on specific clinical scales than a comparative control group. Results indicated that mother-perpetrators displayed significantly higher, elevations on the Psychasthenia (Pt) and Schizophrenia (Sc) scales and a trend toward significantly higher elevation on the Psychopathic Deviate (Pd) scale than the control group. These findings, along with the demographic information obtained, establish a preliminary foundation for understanding an overall profile of mother-perpetrators. 相似文献

A survey of state mental health agencies found that a majority have no specific policy or procedure regarding how to provide mental health services to persons who are deaf or who are deaf-blind. Agency representatives report that staff lack knowledge of how to provide mental health services to persons who are deaf-blind and the agencies lack qualified interpreters. They recommend training for social workers and counselors to address best practices in working with people who are deaf-blind concerning communication methods and strategies, physical interaction, cultural issues, everyday life, sensory deprivation, ethics, use of an interpreter, and other general issues. 相似文献
