Recent studies have documented substantial penalties associated with motherhood and suggest that discrimination plays an important role in producing them. In this article, I argue that the degree to which motherhood is conceptualized as a choice affects the penalties associated with making this choice. Two methods are employed to evaluate this argument. The first method is an analysis of state differences in the wage penalties for motherhood, in which hierarchical linear modeling is used with data from the 1988–2004 Current Population Survey. The second method is a hiring experiment in a highly controlled setting. The wage analysis shows that, net of the usual individual and state‐level factors that affect wages, mothers are penalized more in states where motherhood is perceived to be a woman's choice. The hiring experiment distinguishes between productivity‐based and discrimination‐based explanations for the penalty and provides strong evidence for a causal relationship between perceptions of choice and discrimination against mothers.  相似文献

Two-dimensional dust shoeprints are often of very high resolution and contain unique features. Lifting these prints in the most effective method may contribute much to preserving these fine details. A research was conducted by experts from Israel and Switzerland to compare gelatin lifters and electrostatic lifters for lifting shoeprints. Several substrates were chosen, and on each material a set of dry dust shoeprints was made. A set of wet prints was made on paper as well. The shoeprints were approximately of the same quality, and the only variable was the nature of the material. On substrates indifferent to the method used, the preferable sequence was tested. Gelatin lifter was superior on most substrates and for wet prints. The superior sequence for using both methods is electrostatic lifting followed by gelatin lifter.  相似文献

Emotional and cognitive changes that occur during adolescence set the stage for the development of adaptive or maladaptive beliefs about emotions. Although research suggests that parents’ behaviors and beliefs about emotions relate to children’s emotional abilities, few studies have looked at parental socialization of children’s emotions, particularly in families with depressed adolescents. The present study examined associations between parent and adolescent meta-emotion philosophies (MEP), defined as thoughts, reactions, and feelings about their own emotions. Additionally, adolescent depressive status was tested as a moderator of relationships between parents’ and adolescents’ MEP. One hundred and 52 adolescents, aged 14–18 (65.8% female), and their parents (148 mothers, 106 fathers) participated in a study on emotion socialization in families of depressed and healthy adolescents. Depressed adolescents (n = 75) and matched healthy adolescents (n = 77) were recruited based on research criteria for mental health status. The sample was largely Caucasian (82%) and of middle socioeconomic class status. Results indicated that mothers’ and fathers’ MEP about their children’s emotions were associated with adolescents’ MEP, although parents’ MEP about their own emotions was unrelated to adolescents’ MEP. Fathers’ MEP about children’s emotions made unique contributions to adolescents’ MEP across both adolescent groups. Adolescents’ depressive status moderated the relationship between mothers’ and adolescents’ MEP such that mothers’ MEP was particularly relevant for depressed adolescents. The continued influence of parents in the emotional lives of adolescents is discussed as well as differences in emotion socialization in families with depressed and healthy adolescents.  相似文献

Mediation is an essential component of custody evaluation and reconciliation services in domestic courts. Data from 306 couples with and without a reported history of domestic violence (DV) who were ordered to attend an assessment for mediation were analyzed to determine differences in the mediation process. More than one third reported a history of DV. Chi-square analysis showed that differences in the mediation process exist between couples reporting DV and couples reporting no DV. A greater proportion of couples with reported DV (a) actually attended the court-mandated assessment session, (b) were deemed unsuitable to participate in the mediation process, (c) were in default of child-support payments, and (d) reported drug and alcohol abuse. No significant differences were found between the two groups in the measured mediation outcomes. Implications for the use of mediation with couples who reported DV and recommendations for future research are discussed.  相似文献
