ABSTRACT: In this paper the authors present the results of preliminary estimates on the effects of changes in the composition of labour forces throughout eight OECD countries during the period 1966-1986. The analysis proceeds in two steps. First, the effect of changes in the distribution of the labour force on group unemployment is computed. Second, the impact of this effect is combined with the direct effect of changes in the distribution of participation on total unemployment rates, to calculate a hypothetical unemployment rate which corresponds to what would have occured had there been no compositional changes. The paper challenges the thesis which sustains that alterations in the age-sex composition of the labour force have exerted an upward pressure on the aggregate unemployment rate.  相似文献

This paper reports a study designed to further validate a measure of quality of college life (QCL) of university students (Sirgy, Grzeskowiak, Rahtz, Soc Indic Res 80(2), 343–360, 2007). Two studies were conducted: a replication study and an extension study. The replication study involved surveys of 10 different college campuses in different countries. The results of the replication study provided additional nomological (predictive) validation support of the measure based on a theoretical model mapping out the antecedents and consequences of satisfaction with college life. With respect to the extension study, the focus was to further test the nomological validity of the QCL measure by arguing and empirically demonstrating that the consequence of QCL is life satisfaction. The extension study involved a survey of three college campuses in different countries. The results were also supportive of the nomological validity of the QCL measure.  相似文献

The purpose of this study was to explore potential influences on marriage and family therapists' comfort level when working with lesbian and gay male clients, including sex, age, race, sexual orientation, political orientation, religious practices of the therapist, as well as the level of support for lesbian and gay male human rights. Participants in this study were 199 experienced therapists. Results indicated that higher levels of religious practices were related to lower levels of support for lesbian and gay male human rights and to lower levels of comfort working with lesbian and gay male clients. When support for lesbian and gay male human rights was considered, the level of religious practices was no longer predictive of comfort working with lesbian and gay male clients.  相似文献

In this article we examine the relationship between extent of gambling for U.S. adults and the distance from their residence to the nearest casino or track. We employ data from a telephone survey of U.S. adults conducted in 2011–2013. The chances that the respondents gambled in the past year, were frequent gamblers, or were problem gamblers were greater if they lived close to a casino. The chances that the respondents gambled in the past year or were frequent gamblers were greater if they lived close to a horse or dog track. The effects of closeness to a casino on the likelihood of past-year gambling, frequent gambling, and problem gambling, as well as the effect of closeness to a track on past-year gambling, extended to about 30 miles from the respondent’s home. In addition, the concentration of casinos within 30 miles of the respondent’s home was positively related to the respondents’ chance of being a frequent or problem gambler. If a respondent had no casinos within 30 miles, he or she had a 2.7 % chance of being a problem gambler; if one casino, a 3.9 % chance; if six or more, a 6.2 % chance. The authors estimate that at least part of this effect is causal.  相似文献

Urbanization is becoming increasingly important in terms of climate change and ecosystem functionality worldwide. We are only beginning to understand how the processes of urbanization influence ecosystem dynamics and how peri-urban environments contribute to climate change. Brisbane in South East Queensland (SEQ) currently has the most extensive urban sprawl of all Australian cities. This leads to substantial land use changes in urban and peri-urban environments and the subsequent gaseous emissions from soils are to date neglected for IPCC climate change estimations. This research examines how land use change effects methane (CH4) and nitrous oxide (N2O) fluxes from peri-urban soils and consequently influences the Global Warming Potential (GWP) of rural ecosystems in agricultural use undergoing urbanization. Therefore, manual and fully automated static chamber measurements determined soil gas fluxes over a full year and an intensive sampling campaign of 80 days after land use change. Turf grass, as the major peri-urban land cover, increased the GWP by 415 kg CO2-e ha?1 over the first 80 days after conversion from a well-established pasture. This results principally from increased daily average N2O emissions of 0.5 g N2O ha?1 d?1 from the pasture to 18.3 g N2O ha?1 d?1 from the turf grass due to fertilizer application during conversion. Compared to the native dry sclerophyll eucalypt forest, turf grass establishment increases the GWP by another 30 kg CO2-e ha?1. The results presented in this study clearly indicate the substantial impact of urbanization on soil-atmosphere gas exchange in form of non-CO2 greenhouse gas emissions particularly after turf grass establishment.  相似文献

The purpose of the current study was to evaluate a measure of gambling protective behaviors and examine the relationship between indices of gambling behavior, including frequency, quantity and problem severity, and the use of gambling protective behaviors. Undergraduates from a large public university (N = 4,014) completed a web-based screening survey comprising measures of gambling and health behaviors, from which those who gambled within the past 6-months (n = 1,922, 48 % of the entire sample) were invited to complete the baseline assessment, including the Gambling Protective Behavior Scale (GPBS). The GPBS was determined to have two subscales, primarily consisting of harm reduction strategies that reduce the money or time spent on gambling, or avoidance strategies that help to minimize engagement in gambling activities. Hierarchical multiple regressions found participants’ sex moderated the relationship between use of protective behavioral strategies and gambling outcomes. However, effects were in the opposite direction to those hypothesized. Specifically, because women gambled less, had lower gambling problem severity, and reported more frequent use of gambling avoidance protective behaviors, the relationship between use of gambling protective behaviors and gambling outcomes was stronger for men than women. Men who used more avoidance strategies gambled less frequently compared to men who used fewer avoidance strategies. Similarly, men who used more harm reduction strategies spent fewer dollars on gambling and had lower scores on gambling problem severity compared to men using fewer harm reduction strategies for women these relationships were less pronounced. Implications of incorporating specific gambling protective behavioral strategies into prevention and treatment programs are discussed.  相似文献

Lesbians have been consistently ignored in empirical psychological research. The current research extends Lee and Crawford's ( 2007 ) comprehensive review, which used both quantitative and qualitative approaches to analyze the amount and kind of research on lesbians. Quantitative measures from 1975-2009 showed that the increase found in Lee and Crawford in 2001 has leveled off and the neglect of lesbians remains pronounced. Using cluster analysis of data derived from content analysis of abstracts published from 2003-2009, we identified six topic groups: Others' Attitudes, Sexual Orientation, Intimate Relationships, Coping and Coming Out, Lesbians' Problems, and Life in Heterosexual Society. In particular, transformative research was scarce and scattered across the identified clusters. Results are discussed in terms of what they reveal about the social construction of lesbianism in psychological research.  相似文献

The number of people identifying as biracial is rapidly growing, though little is known about the experiences of interracial families. Previous work indicates that biracial children may be at elevated risk of entering the child welfare system. This could underscore additional risks faced by these families. This document includes data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN), a project funded by the Administration on Children, Youth, and Families, U.S. Department of Health and Human Services, and distributed by the National Data Archive on Child Abuse and Neglect. LONGSCAN data were used to examine familial risks associated with child maltreatment. White mothers of white children were compared to white mothers of biracial children with the hypothesis that interracial families would have less social and community support. Results showed that the women were similar in terms of mental health and parenting behaviors. There were no differences in maternal age, employment status, or presence of a partner. However, mothers of biracial children were poorer, had more alcohol use, and decreased social support. They experienced more intimate partner violence and lower neighborhood satisfaction. Findings have implications for intervention programs focused on reducing social isolation within interracial families.  相似文献
