This study examines the relationship between attachment to parents and peers, time perspective and psychological adjustment
in adolescence. 2,665 adolescents (M age = 17.03 years, SD = 1.48) completed self-report measures about parent and peer attachment,
time perspective, sympathy and self-determination. Subjects were divided into four groups based on their parent and peer attachment
scores: high parent and high peer attachment, low peer and low parent, high parent and low peer, low parent and high peer.
Higher levels of negative past of the Zimbardo Time Perspective Inventory were revealed, by post hoc analyses, in the group
with low attachment to parent and peer. Unlike adolescents with low attachment to parents, adolescents who reported a secure
attachment to parents had higher scores on positive past, hedonistic present, and future. Adolescents with high attachment
to parent and peer and adolescents with high parent but low peer attachment had the highest scores on competence and authonomy. 相似文献

We propose a new principle of ‘non-interference’ applied to social welfare orderings. The principle, together with two other
standard requirements, implies a strong egalitarian conclusion: the ordering must lexicographically maximize the welfare of
the worst off.

A growing literature has examined the prevalence of transnational engagement among children of immigrants. However, few studies have been equipped to analyse underlying dynamics that serve to impede or perpetuate transnational practices among them in the United States. In this article, we compare transnationalism narratives between 1.5- and second-generation children of immigrants to more fully adjudicate enduring transnational ties over time. Our analysis of 134 interviews from the Children of Immigrants Longitudinal Study suggests that children of immigrants from Southern California conceptualise transnational experiences in diverse but remarkably similar ways. The meanings attached to transnational behaviours and identities employ certain patterns, and are often related to strength of kin-based ties, ethnic language fluency, and levels of structural access to the homeland. Moreover, findings indicate that the second-generation is nearly as transnationally engaged as the 1.5-generation. This provides novel but limited evidence in support of claims that transnational ties are sustained across generations. 相似文献

Older women often experience pain in their daily lives. This article provides an overview of topics addressed in the geriatric pain research published between 1999 and 2004. New areas of emphasis of research have emerged such as the recognition of body mass and weight as a factor in persistent pain, while other areas have expanded, including the focus on pain among elders with cognitive impairments and the use of alternative treatment approaches. Understanding of pain in late life is hindered by study samples that lack diversity, treatment approaches that are narrowly focused, and a lack of attention to quality of life issues. 相似文献

AbstractThis study develops and empirically tests, from the resource-based perspective, a conceptual framework linking green supply management and performance. The proposed model is tested using data from a sample of 126 automotive manufactures in China. The results suggest that both green purchasing personnel and green supplier selection have a significant positive effect on green supplier collaboration, and that building green collaboration with suppliers is significantly and positively related to both environmental and operational performance. Accordingly, knowledge and skill development of the purchasing function can be recognised as an important resource in building green supply capabilities and performance. 相似文献

Alba González-Roz José R. Fernández-Hermida Sara Weidberg Victor Martínez-Loredo Roberto Secades-Villa 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2017,33(2):371-382
The high availability and accessibility of online gambling have recently caused public concern regarding the potential increase of gambling-related problems among young people. Nonetheless, few studies among adults and none among adolescents have explored specific characteristics of gamblers as a function of gambling venues to date. This study sought to analyze the prevalence of gambling among a sample of adolescents in the last year, as well as sociodemographic and gambling-related characteristics as possible predictors of at-risk and problem gambling. The sample comprised 1313 adolescents aged 14–18 years. Participants were asked to respond to several questions regarding their gambling behavior. Chi square and ANOVA tests were performed in order to explore differences between groups, and a set of multinomial regressions established significant severity predictors. The prevalence of at-risk and problem gambling was 4 and 1.2 %, respectively. Regression analyses showed that having a relative with gambling problems predicted at-risk gambling. Both living with only one parent or not living with parents at all, and the prevalence of Electronic Gambling Machines in the last year were associated with problem gambling. Mixed-mode gambling was a predictor of both at-risk and problem gambling. Our findings extend previous research on gambling among adolescents by exploring gambling behavior according to different modes of access. Although the prevalence of exclusive online gambling among the total sample was low, these results support the need to consider specific subgroups of gamblers and their concrete related features when conducting both indicated prevention and treatment protocols for adolescents. 相似文献

Data from Virginia Adult Protective Services (APS) case files of 95 abused women aged 60 years and older were assessed to establish demographic trends; ability to care for self; type, pattern, and place of abuse; information on witnesses and alleged offenders; and case resolution and outcomes. The most common types of mistreatment reported were neglect, exploitation, and physical abuse. The women typically had several functional limitations and were dependent upon their family members for care. Most cases were not prosecuted, and the majority of women remain at risk for further abuse. Implications of these data for future research and practice are discussed. 相似文献

In this paper we consider the optimal decomposition of Bayesian networks. More concretely, we examine empirically the applicability of genetic algorithms to the problem of the triangulation of moral graphs. This problem constitutes the only difficult step in the evidence propagation algorithm of Lauritzen and Spiegelhalter (1988) and is known to be NP-hard (Wen, 1991). We carry out experiments with distinct crossover and mutation operators and with different population sizes, mutation rates and selection biasses. The results are analysed statistically. They turn out to improve the results obtained with most other known triangulation methods (Kjærulff, 1990) and are comparable to results obtained with simulated annealing (Kjærulff, 1990; Kjærulff, 1992). 相似文献

The dramatic global transition to democracy of the last decade reveals important systematic patterns. Using recent contributions to world-systems theory, this study examines the relationship between political regime changes and the position of nations in the world-economy over the last two decades, to argue that democratic transitions have been centered among semiperipheral nations. The study also found a strong relationship between the structure of the labor force and the global distribution of democratic institutions, but a weak relationship between the structure of the labor force and the timing of transitions in the semiperiphery. Overall, the findings suggest that world-systemic categories provide a useful vantage point to distinguish global trends from the specific characteristics of individual nations, thereby allowing for greater analytical precision in identifying the crucial causal relations shaping transitions from dictatorship to democracy. 相似文献

Summary In the log-linear model for bivariate probability functions the conditional and joint probabilities have a simple form. This
property make the log-linear parametrization useful when modeling these probabilities is the focus of the investigation. On
the contrary, in the log-linear representation of bivariate probability functions, the marginal probabilities have a complex
form. So the log-linear models are not useful when the marginal probabilities are of particular interest. In this paper the
previous statements are discussed and a model obtained from the log-linear one by imposing suitable constraints on the marginal
probabilities is introduced.
