While most pathological gamblers, like most alcohol abusers, recover on their own, it seems likely that they are at greater risk for relapse than those who have been through successful treatment. Accordingly, a substantial increase in treatment resources for pathological gamblers, along with greater efforts to establish the effectiveness of these treatments, ought to receive national priority. If the data on alcohol-abusing self-changers are generalizable to self-changing pathological gamblers, the prognosis for gamblers who stop gambling all together is better than for those who aspire to controlled or nonproblem gambling. While pathological gamblers with comorbid substance abuse are more difficult to treat than those without it, the impact of comorbid substance abuse on the decision by pathological gamblers to change has not yet been explored, although it should be. Similarly, the impact of other Axis I pathology on pathological gambling self-change, especially depression and anxiety, should be thoroughly explored. The most pressing problem in this field appears to be definitional. As a consequence, until consensus is reached on a reliable, valid, and useful classification scheme for pathological gambling, both research and clinical efforts will continue to suffer.  相似文献

In this article, a bivariate generalisation of the gamma distribution is proposed by using an unsymmetrical bivariate characteristic function; an extension to the non central case also receives attention. The probability density functions of the product and ratio of the correlated components of this distribution are also derived. The benefits of introducing this generalized bivariate gamma distribution and the distributions of the product and the ratio of its components will be demonstrated by graphical representations of their density functions. An example of this generalized bivariate gamma distribution to rainfall data for two specific districts in the North West province is also given to illustrate the greater versatility of the new distribution.  相似文献

The performance of pay-as-you-go old-age insurance under different demographic conditions can be estimated from a metric consisting of the implicit rate of return to successive cohorts. We show a positive return for the prospective population over the next few years, but for cohorts born after the end of the century returns will become sharply negative. A decline in returns is typical of pay-as-you-go schemes as they mature, and a change to negative returns is typical in particular as the birth rate falls under fixed economic conditions. The return can be kept positive by greatly increased fertility or immigration. Taking labour-force participation rates into account, and supposing entitlement independent of contribution, gives much larger negative rates of return, however. The main calculations considered here are for schemes with a constant pension. If the contribution rather than the pension is kept constant then the disparities between cohorts with respect to their returns are smaller, and although the negative returns for future generations then set in earlier they are smaller. The conclusions of the paper are broadly applicable to any population that showed a baby boom after World War II and replacement-level or lower fertility subsequently.  相似文献

This paper uses longitudinal survey data to assess factors affecting the duration of unemployment in Russia. We examine four types of marginalised labour force participants, according to ILO guidelines and survey responses, and we estimate duration models for each type. It turns out that the sets of characteristics with the strongest effects on the duration are remarkably similar across the different unemployment definitions and model specifications. Therefore, despite the formidable practical measurement problems, problematic groups of individuals can actually be identified. Received: 27 January 1999/Accepted: 27 January 2000  相似文献

Behavioral economists increasingly argue that violations of rationality axioms provide a new rationale for paternalism – to “de-bias” individuals who exhibit errors, biases and other allegedly pathological psychological regularities associated with Tversky and Kahneman’s (in Science 185:1124–1131, 1974) heuristics-and-biases program. The argument is flawed, however, in neglecting to distinguish aggregate from individual rationality. The aggregate consequences of departures from normative decision-making axioms may be Pareto-inferior or superior. Without a well-specified theory of aggregation, individual-level biases do not necessarily imply losses in efficiency. This paper considers the problem of using a social-welfare function to decide whether to regulate risk-taking behavior in a population whose individual-level behavior may or may not be consistent with expected utility maximization. According to the social-welfare objective, unregulated aggregate risk distributions resulting from non-maximizing behavior are often more acceptable (i.e., lead to a weaker rationale for paternalism) than population distributions generated by behavior that conforms to the standard axioms. Thus, psychological theories that depart from axiomatic decision-making norms do not necessarily strengthen the case for paternalism, and conformity with such norms is generally not an appropriate policy-making objective in itself.  相似文献

Based on an ethnographic study of transnational networks of alumni of an academically selective boarding school in Havana, this article explores the nexus between mobility, schooling and belonging in the context of socialist Cuba and its diaspora. Drawing on Goffman’s work, I argue that the boarding school experience was transformative; it facilitated or consolidated social mobility for its pupils, which later, for many, led to geographic mobility in the form of study and work outside Cuba. After graduating, alumni continue to identify with the school and to reproduce their alumni identities. The affective webs of belonging forged through family links and friendships fostered at the school constitute emotionally sustaining networks that also provide material support after migrating. I propose that the school represents a site of identification for a globally dispersed non-national diaspora and argue that migration scholars need to embed international migration within people’s lives more broadly.  相似文献

This article examines the different aspects of female genital mutilation (FGM) which is more commonly known as "female circumcision." It also discusses the Women-at-Risk Program in Canada, mental health issues, and Canadian laws and bans on this practice. Implications of FGM for the social work are also addressed. FGM is a global issue, occurring across different cultures and ethnic groups. It is estimated that between 85 and 14 million women have been mutilated worldwide. There are three forms of FGM: circumcision, excision, and infibulation. Despite the many serious risks arising from these procedures, the practice still continues for reasons that are often based on myths, tradition, and beliefs that religion requires it. Females can suffer from severe consequences of FGM. Various fields, which address health needs, however, failed to recognize the physical and psychological impact of the practice, and have not effectively trained health workers to confront this issue. Putting an end to FGM requires a global action from professionals in mental health, social work, medicine and nursing to challenge laws and lobby for new policies; advocate for the human rights of women and children; negotiate for changes in the health care system to address the needs of women have been mutilated; and create educational literature, thus, increasing awareness on FGM.  相似文献

This study examined gender differences in the level and developmental course of relational aggression in middle childhood, as well as early predictors and outcomes of relational aggression, after controlling for concurrent physical aggression. Relational (RAgg) and Physical aggression (PAgg) scores for 558 boys and 545 girls at the ages of eight to 11 in the NICHD Study of Early Child Care and Youth Development (SECCYD) were created by combining the highest rating for each item across mother and teacher reports. Longitudinal analyses were conducted using latent curve models of RAgg with PAgg as a time‐varying covariate, with all parameters allowed to vary by gender. Boys and girls had different growth parameters of RAgg. Girls' RAgg intercept was higher, and the slope was not different from zero; boys' RAgg intercept was lower, and the slope declined. Mother–child conflict in early childhood predicted RAgg intercept for both boys and girls, but maternal harsh control and sensitivity were also uniquely predictive for girls whereas center care was uniquely predictive for boys. RAgg intercept predicted adolescent self‐reports of depression for girls and delinquency and risk‐taking for both boys and girls; the magnitude of the association with risk taking was significantly greater for boys.  相似文献

Despite international terrorism's increasing relevance for international business, the effects of terrorism that confront employees during assignments abroad have hardly been investigated. Applying a stress perspective, this article analyzes the impact of terrorism-induced stress on attitudes and the performance of expatriates. Employing data from 143 expatriate managers in high-risk countries, the study shows that several terrorism-related stressors create a significant stress level for the individual, causing negative work attitudes and attitudes towards host country nationals (disaffection). This eventually leads to worse performance. We applied partial least squares (PLS) structural equation modeling (SEM) to analyze the entire impact path and found substantial support for our hypotheses. Of all the relevant stressors, intra-family conflicts due to terrorism have the greatest impact.  相似文献

The current analysis was designed to critically examine the tendency to focus on child maltreatment as a unique risk factor and test the resulting assumption of a direct causal relationship between early maltreatment and later behavioral problems. The variation seen in behavioral outcomes among children reported for maltreatment early in life led us to hypothesize that the cumulative level of risk facing children and their families can, at least in part, account for that variation in outcome. Participants were 242 mothers of predominantly at-risk newborn infants who were interviewed shortly after giving birth. The State Central Registry of Maltreatment was then reviewed over each child's first four years of life to assess for early maltreatment. Following the neonatal interviews, mothers completed the Child Behavior Checklist when their children were 4, 6, 8, 10 and 12 years-of-age. Although early maltreatment report does appear to be important to early child functioning, the cumulative level of risk more strongly predicts long-term clinical behavioral difficulty. High-risk children who were not reported for maltreatment by age 4 demonstrate greater behavioral problem trajectories than did low-risk children with a maltreatment report. Maltreatment itself may be best conceptualized as an important, but not singularly so, risk factor for later behavioral problems. In focusing directly on reported maltreatment, our child protective systems may be paying too little attention to what else is going wrong in the lives of children and targeting intervention efforts in the wrong direction. When it comes to early maltreatment our child protective policy and practice need to broaden their lenses to include greater emphasis on overall family functioning, stress and well-being. Early maltreatment, it seems, may be a symptom of more profound problems in the early environments of our most vulnerable children, rather than the problem itself.  相似文献
