Evidence suggests that paternity leave‐taking is associated with higher levels of father involvement, but research has been limited in its focus on cross‐sectional analyses and indicators of father involvement used. This study uses national longitudinal data to examine whether paternity leave‐taking is associated with 2 indicators of father engagement when children are infants, whether paternity leave‐taking is associated with trajectories of father engagement during the first few years of a child's life, and whether the relationships between paternity leave and father engagement are explained by fathering commitments and attitudes. The results suggest that longer periods of leave are associated with more frequent engagement in developmental tasks and caretaking when children are infants as well as during the first few years of children's lives. There is also evidence that father attitudes partially explain the relationships between length of paternity leave and father engagement. 相似文献

Stepparent–stepchild relationships can be difficult to develop and research suggests that the quality of these relationships affects stepfamily functioning and child well-being. This qualitative study explored experiences and perceived determinants of stepchild abuse among 16 youths who are stepchildren on the University of Ghana campus. Positive experiences included receipt of material and emotional support and difficult experiences included favoritism, subjection to severe disciplinary measures, and neglect. Impacts of these experiences were reported. Perceived determinants of stepchild abuse included lack of biological relation, personality of stepparent, financial constrain, stepparent’s past experiences, and inheritance. Implications of the findings are discussed. 相似文献

Longitudinal Relations of Economic Hardship and Effortful Control to Active Coping in Latino Youth 下载免费PDF全文
Zoe E. Taylor Keith F. Widaman Richard W. Robins 《Journal of research on adolescence》2018,28(2):396-411
How Latino youth cope with stressors may have implications for their adjustment. We examined how a temperamental characteristic (effortful control) and a contextual factor (economic hardship) were associated with Latino youth's coping. Individual differences in effortful control, a core facet of self‐regulation, may contribute to coping as effortful control is consistently linked to adaptive behaviors during adolescence. We examined relations of effortful control and economic hardship to active coping in a sample of Mexican‐origin youth (N = 674) across three time points (fifth to ninth grades). Although economic hardship negatively predicted coping and effortful control, effortful control positively predicted coping (controlling for prior levels). Findings support a resilience perspective by suggesting that effortful control may contribute to coping and thus counteract the negative effects of economic hardship. 相似文献

In the Mediterranean, long-term land-use changes have resulted into landscape mosaics composed of very few ancient woodland remnants scattered across extended post-agricultural woodlands. Patches of ancient woodlands are now suffering rapid urban growth that reduces their area and impact their associated biodiversity. Here we use the case study of Montpellier, one of the most dynamic cities in France, to 1) characterize temporal changes in land covers (between 1860 and 2006) in its area, and 2) using two guilds of fungal bioindicators (i.e., polypores and lichens), to compare biodiversity stakes between ancient and secondary Mediterranean woodlands. We used a combination of historical maps, archives, fungal collections and field survey in eight Quercus ilex patches (4 ancient versus 4 recent replicates) to reconstruct landscapes dynamics and assess biodiversity changes. From the 19th to the 21st century, over half (52.4%) of the ancient woodlands within Montpellier were replaced by other land covers, mainly by urban equipment, while secondary patches (16.8% of the total area) were naturally established. Remaining ancient woodlands show multi-layered vegetation made of multi-secular Pinus halepensis dominating a dynamic understorey made of Quercus ilex and various Mediterranean shrubs. Polypores, but not macrolichens, tended to differ in community composition between ancient and recent woodland patches, with the highest diversity found in ancient woodlands. This study highlights that urban woodland patches of contrasted histories harbour distinct biodiversity stakes to be included in urban planning and provide valuable areas to evaluate biodiversity patterns and dynamics. 相似文献

Most gambling studies have a gender-blind research approach, although a large body of scientific evidence suggests that gambling in females is on the rise and that males and females have different gambling behaviours and experience specific gambling-related harm. This study addressed these gender differences using a network analysis, an innovative approach considering disorders/concepts as dynamic systems of interacting symptoms/items. Data on gambling activities, problem gambling, substance use and mental health were collected in a representative sample of French adult gamblers (n = 8805). The study capitalized on the network analysis directly to compare associations of specific gambling activities with gambling disorder symptoms separately for both genders. The network analysis revealed that problem gambling was strongly associated with gambling machines among females, whereas it was related to sports betting, poker and casino games among males. The networks that included substance use and mental health showed that substance use was related to specific gambling activities. These findings confirm the links between various gender-specific gambling patterns and problem gambling and suggest a need to consider these gender differences to improve prevention efforts. More broadly, the present study further supports the importance of gender differences for gambling research and policy. 相似文献

The objective of this study is to explore the gambling participations and game purchase duplication of light regular, heavy regular and pathological gamblers by applying the Duplication of Purchase Law. Current study uses data collected by the Australian Productivity Commission for eight different types of games. Key behavioral statistics on light regular, heavy regular, and pathological gamblers were computed and compared. The key finding is that pathological gambling, just like regular gambling, follows the Duplication of Purchase Law, which states that the dominant factor of purchase duplication between two brands is their market shares. This means that gambling between any two games at pathological level, like any regular consumer purchases, exhibits “law-like” regularity based on the pathological gamblers’ participation rate of each game. Additionally, pathological gamblers tend to gamble more frequently across all games except lotteries and instant as well as make greater cross-purchases compared to heavy regular gamblers. A better understanding of the behavioral traits between regular (particularly heavy regular) and pathological gamblers can be useful to public policy makers and social marketers in order to more accurately identify such gamblers and better manage the negative impacts of gambling. 相似文献

The pathways model of problem gambling suggests the existence of three developmental pathways to problem gambling, each differentiated by a set of predisposing biopsychosocial characteristics: behaviorally conditioned (BC), emotionally vulnerable (EV), and biologically vulnerable (BV) gamblers. This study examined the empirical validity of the Pathways Model among adolescents followed up to early adulthood. A prospective-longitudinal design was used, thus overcoming limitations of past studies that used concurrent or retrospective designs. Two samples were used: (1) a population sample of French-speaking adolescents (N = 1033) living in low socio-economic status (SES) neighborhoods from the Greater Region of Montreal (Quebec, Canada), and (2) a population sample of adolescents (N = 3017), representative of French-speaking students in Quebec. Only participants with at-risk or problem gambling by mid-adolescence or early adulthood were included in the main analysis (n = 180). Latent Profile Analyses were conducted to identify the optimal number of profiles, in accordance with participants’ scores on a set of variables prescribed by the Pathways Model and measured during early adolescence: depression, anxiety, impulsivity, hyperactivity, antisocial/aggressive behavior, and drug problems. A four-profile model fit the data best. Three profiles differed from each other in ways consistent with the Pathways Model (i.e., BC, EV, and BV gamblers). A fourth profile emerged, resembling a combination of EV and BV gamblers. Four profiles of at-risk and problem gamblers were identified. Three of these profiles closely resemble those suggested by the Pathways Model. 相似文献

The Role of Mothers' Communication in Promoting Motivation for Math and Science Course‐Taking in High School 下载免费PDF全文

In the context of concerns about American youths' failure to take advanced math and science (MS) courses in high school, we examined mothers' communication with their adolescent about taking MS courses. At ninth grade, U.S. mothers (n = 130) were interviewed about their responses to hypothetical questions from their adolescent about the usefulness of algebra, geometry, calculus, biology, chemistry, and physics. Responses were coded for elaboration and making personal connections to the adolescent. The number of science, technology, engineering, and mathematics courses taken in 12th grade was obtained from school records. Mothers' use of personal connections predicted adolescents' MS interest and utility value, as well as actual MS course‐taking. Parents can play an important role in motivating their adolescent to take MS courses. 相似文献

Adolescent Athletic Participation Patterns and Self‐Perceived Competence: Associations With Later Participation,Depressive Symptoms,and Health 下载免费PDF全文
Jennifer P. Agans Sara K. Johnson Richard M. Lerner 《Journal of research on adolescence》2017,27(3):594-610
Physical activity is important for well‐being across the life span. However, links between patterns of adolescent activity, competence perceptions, and young adult outcomes are underexplored. We used data from seven waves of the 4‐H Study of Positive Youth Development (N = 5,961) to assess patterns of adolescent athletic participation, whether these patterns were associated with self‐perceived athletic competence and young adult physical activity, depressive symptoms, and health, and associations between changes in participation across adolescence and young adult outcomes. Competence perceptions were associated with increased participation, and more active adolescents had higher rates of adult athletic activity, with links to better health and fewer depressive symptoms. We discuss results in light of the importance of using person‐centered analyses to understand active lifestyles. 相似文献
