Betancourt LM Brodsky NL Brown CA McKenna KA Giannetta JM Yang W Romer D Hurt H 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2012,28(2):225-238
Our objectives for this report were to identify trajectories of youth gambling behavior, and to examine their relation to
executive cognitive function (ECF) and associated problem behaviors. Philadelphia school children, enrolled at ages 10–12 years
(n = 387; 49% male), completed three annual assessments of risk behaviors, ECF, impulsivity, problem behaviors and demographics.
Across ages 10–15 years, using methods from Nagin et al., two groups were identified: Early Gamblers (n = 111) initiated early and continued in later assessments, and Later Gamblers (n = 276) initiated at later ages and gambled less. Betting money on cards and sports were the most frequently reported gambling
behaviors. Using gambling group as outcome, final backward selection logistic regression model showed Early Gamblers are more
likely male (P = 0.001), report more active coping (P = 0.042), impulsive behaviors (P ≤ 0.008), and have friends who gamble (P = 0.001). Groups were similar in ECF, parental monitoring, marital status, SES, and race. Early Gamblers had higher incidence
of problem behaviors and drug use (all P ≤ 0.006). Two gambling groups were identified in early adolescence with Early Gamblers showing higher levels of impulsivity
and comorbid problems but similar levels of ECF compared to Late Gamblers. As more gambling groups are identified through
later adolescence, ECF may emerge as a relevant precursor of problem gambling at this later time. 相似文献

Family Influences on Mexican American Adolescents’ Romantic Relationships: Moderation by Gender and Culture 下载免费PDF全文

This study examined prospective associations between the family context and adolescents’ romantic relationships as moderated by adolescents’ gender and culture among Mexican American families (N = 189). Adolescents at Time 1 (early adolescence) were on average 12.29 years of age (SD = 0.50) and 54% female. Mothers and fathers reported on family structure and dynamics during early adolescence, and youth reported on their romantic relationship involvement and quality during middle and late adolescence. Results from path analyses indicated that family structure and dynamics (supportive parenting, consistent discipline, and parent–adolescent and interparental conflict) were associated with adolescents’ romantic involvement and quality, and with differences by adolescents’ gender and culture. Findings highlight Mexican American family contexts that contribute uniquely to adolescents’ romantic relationships. 相似文献

We propose a spatial model of producer market access where local middlemen reap market power due to match friction, and fair traders enter to present an alternative. The model features location as a key determinant of the impact of fair trader entry on the market share of fair traders, the distribution of consumer willingness to pay between middlemen and producers, and intra- / inter-regional poverty incidence. For governments who wish to minimize the poverty gap, our results support directing resources to subsidize fair trade organizations, and/or to producers with no access to markets, rather than to local middlemen intermediaries. 相似文献

Using a developmental systems perspective and public‐use longitudinal data from participants currently in a romantic relationship at Wave 4 of the National Longitudinal Study of Adolescent Health (n = 2,970), the current study explored direct and indirect paths from parent–adolescent relationship quality to young adult intimate relationship quality. Structural equation modeling tested whether mental health (depressive symptoms and self‐esteem) in the transition to adulthood mediated the association between parent–adolescent relations and young adult intimate relations. The results indicated that higher quality parent–adolescent relations predicted higher self‐esteem and lower depressive symptoms during the transition to adulthood as well as higher young adult intimate relationship quality, controlling for adolescent mental health and parent–young adult relationship quality. Higher self‐esteem during the transition to adulthood was associated with greater intimate relationship quality, whereas greater depressive symptomatology predicted reduced intimate relationship quality. One significant indirect path emerged: parent–adolescent relationship quality → self‐esteem → intimate relationship quality. 相似文献

Recent research has demonstrated a relationship between infants' tonic electroencephalogram (EEG) patterns and approach‐style jealousy responses (Mize & Jones, 2012 ). Although it has been found that adults exhibit approach‐style neural activity during jealousy paradigms (Harmon‐Jones, Peterson, and Harris, 2009 ), parallel research on neural activity during a jealousy paradigm in infants is lacking from the literature base. The purpose of the current research is to examine EEG patterns of 35 infants (Mean age = 8.92 months old) in a social‐rival paradigm designed to elicit jealousy responses. Consistent with past research, infants demonstrated more approach‐style, jealousy‐related behaviors when their mothers attended to a social‐rival than to a nonsocial rival. Additionally, infants demonstrated approach‐style anterior EEG activity during the social‐rival condition, a pattern that is associated with jealousy. The current findings suggest that the physiological underpinnings for the emotions that motivate the protection of important dyadic relationships are in place early in ontogeny. Therefore, jealousy‐type behaviors and physiological responses begin to be observable as early as 9‐months‐old when maternal attention is lost to a social‐rival. 相似文献

During the #MeToo movement, social movement organizations (SMOs) played a crucial role in the online mobilization by utilizing various message frames and appealing hashtags during the social movement. Applying a co-creational approach and using framing as a theoretical framework, the study explored how SMOs use words and hashtags to participate in the #MeToo movement through Twitter. Based on both semantic network analysis and thematic analysis methods, findings of the study enhance literature of social movement organizations and activism as well as provide practical implications for effective social movement campaigns. 相似文献

Moderation and mediation models of religiosity and effortful control as predictors of tobacco and alcohol use were tested in this 2‐year longitudinal study of 563 16‐year‐old Muslim Indonesian adolescents. Adolescents reported their effortful control, religiosity, and tobacco and alcohol use and peers provided reports of adolescents’ effortful control. Although both moderation and mediation effects emerged when predicting Year 2 substance use, predictions of change from Year 1 to Year 2 substance use yielded effects of moderation for peer‐ but not self‐reported effortful control for boys; no mediation effects emerged. These findings provide evidence of interconnections between effortful control and religiosity as predictors of substance use and suggest the need for further longitudinal studies that compare moderation and mediation models. 相似文献

Little is known about the environmental factors that limit the demography and abundance of wild vertebrates in highly modified urban environments. The House Sparrow Passer domesticus is a globally widespread species whose urban populations have recently undergone substantial declines particularly in Europe. The environmental drivers of these declines remain unknown. In a previous study we showed that invertebrate availability during the breeding season limited reproductive success but not population size in a suburban sparrow population. In this study we test experimentally whether year-round food availability limits demography and population size. Supplementary feeding involved the provision of invertebrate prey (during the breeding season) plus unlimited high-energy seed (year-round) at 33 sparrow colonies spread across suburban London over two successive calendar years. Thirty-three unfed colonies served as controls. Supplementary feeding increased fledgling abundance, but had no impact on overwinter survival or population size. We conclude that this depleted suburban sparrow population is not limited by food availability, and conservation efforts based primarily on food provision are unlikely to succeed. We also tested whether cross-colony variation in sparrow abundance was correlated with a set of potential environmental stressors including measures of predator abundance and pollution. Sparrows were more abundant, or showed more positive temporal changes in abundance, at localities containing large areas of seed-rich habitat and low levels of nitrogen dioxide air pollution. Further research is merited into the potential impacts of air pollution on the fitness of urban birds. 相似文献

ABSTRACTChanging filial piety expectations have been examined from the viewpoint of younger generations. However, research on older adults’ perspective of this cultural phenomenon is virtually absent from the empirical literature. In an effort to address the changing family life circumstances of Korean and Korean-American families, this study explores older adults’ filial expectations from their own children and correlated factors associated with the expectation. The cross-sectional survey study with 449 older adults found that the majority of respondents still believe that adult children should assume responsibility for the care of their parents. Several factors such as age, education, income, living arrangements, self-rated health, year of immigration, and social support were significantly correlated with filial expectations among older Korean-Americans. Only satisfaction with social support received from family and friends was significantly related to older Koreans’ expectations. Implications for social work practice are discussed and further research directions are suggested. 相似文献

Generations need to spend time in meaningful activities to facilitate more healthy interactions. An interdisciplinary team worked together to implement an enriching, intergenerational project with 4 year olds, college students, and older adults. College students played an active role in planning/facilitating activities. The overall objective of the research was assessing perceptional change between the generations using pre/posttests with college students, pre-post interviews with older adults, and pre-post teacher led discussions with children. Findings suggest that older adults and college students had improved perceptions. Children’s perceptions remained negative with some positive perceptions. 相似文献
