Poker-machine gamblers have been demonstrated to report increases in the urge to gamble following exposure to salient gambling cues. However, the processes which contribute to this urge to gamble remain to be understood. The present study aimed to investigate whether changes in the conscious experience of visual imagery, rationality and volitional control (over one’s thoughts, images and attention) predicted changes in the urge to gamble following exposure to a gambling cue. Thirty-one regular poker-machine gamblers who reported at least low levels of problem gambling on the Problem Gambling Severity Index (PGSI), were recruited to complete an online cue-reactivity experiment. Participants completed the PGSI, the visual imagery, rationality and volitional control subscales of the Phenomenology of Consciousness Inventory (PCI), and a visual analogue scale (VAS) assessing urge to gamble. Participants completed the PCI subscales and VAS at baseline, following a neutral video cue and following a gambling video cue. Urge to gamble was found to significantly increase from neutral cue to gambling cue (while controlling for baseline urge) and this increase was predicted by PGSI score. After accounting for the effects of problem-gambling severity, cue-reactive visual imagery, rationality and volitional control significantly improved the prediction of cue-reactive urge to gamble. The small sample size and limited participant characteristic data restricts the generalizability of the findings. Nevertheless, this is the first study to demonstrate that changes in the subjective experience of visual imagery, volitional control and rationality predict changes in the urge to gamble from neutral to gambling cue. The results suggest that visual imagery, rationality and volitional control may play an important role in the experience of the urge to gamble in poker-machine gamblers.  相似文献

Risks associated with toxicants in food are often controlled by exposure reduction. When exposure recommendations are developed for foods with both harmful and beneficial qualities, however, they must balance the associated risks and benefits to maximize public health. Although quantitative methods are commonly used to evaluate health risks, such methods have not been generally applied to evaluating the health benefits associated with environmental exposures. A quantitative method for risk-benefit analysis is presented that allows for consideration of diverse health endpoints that differ in their impact (i.e., duration and severity) using dose-response modeling weighted by quality-adjusted life years saved. To demonstrate the usefulness of this method, the risks and benefits of fish consumption are evaluated using a single health risk and health benefit endpoint. Benefits are defined as the decrease in myocardial infarction mortality resulting from fish consumption, and risks are defined as the increase in neurodevelopmental delay (i.e., talking) resulting from prenatal methylmercury exposure. Fish consumption rates are based on information from Washington State. Using the proposed framework, the net health impact of eating fish is estimated in either a whole population or a population consisting of women of childbearing age and their children. It is demonstrated that across a range of fish methylmercury concentrations (0-1 ppm) and intake levels (0-25 g/day), individuals would have to weight the neurodevelopmental effects 6 times more (in the whole population) or 250 times less (among women of child-bearing age and their children) than the myocardial infarction benefits in order to be ambivalent about whether or not to consume fish. These methods can be generalized to evaluate the merits of other public health and risk management programs that involve trade-offs between risks and benefits.  相似文献

We examine the relationship between gambling and criminal behaviour using data from the National Longitudinal Study of Adolescent Health (Add Health). Our data set includes survey responses from 6145 young adults. The results of our empirical analysis are consistent with the gambling literature in which it is suggested that higher gambling losses increase the propensity to commit crime. This study complements the current literature, as our data and empirical analysis allow us to control for many variables that have been neglected in previous studies, including various forms of gambling. Our findings provide useful information on the general relationship between gambling behaviour and criminal behaviour.  相似文献

While human rights treaties have become increasingly popular over the past quarter century, there has not been a corresponding improvement in human rights practices. This discrepancy implies that a country's formal pledge to uphold human rights principles is "loosely coupled" from its actual performance. In this study, I develop a model of loose coupling based on organizational research and apply it to the human rights sector of the world polity. Empirically, I identify a set of institutional states whose human rights practices fall short of their treaty commitments, as well as a set of technical states whose practices exceed their commitments. Analyzing an unbalanced data set with a maximum of 755 observations across 167 countries during the 1975 to 2000 period, I use random effects models to predict a state's location on the Human Rights Decoupling Index (HRDI). The findings illustrate the importance of several organizational concepts for predicting a state's HRDI score. In particular, the analyses reveal the countervailing effects of globalization. While economic globalization (i.e., trade and foreign investment) is associated with the technical (positive) end of the HRDI, cultural globalization (i.e., memberships in international organizations) is associated with the institutional (negative) end.  相似文献

Young South African fathers are often engaged in their children's lives even if they do not live together. Using longitudinal data on children (n = 1,209) from the Cape Town area, the authors show that although only 26% of young fathers live with their children, 66% of nonresidential fathers maintain regular contact, and 61% provide financial support. The father–child relationship, however, is embedded in broader family ties. The type of father–mother relationship is strongly associated with whether fathers coreside with their children but not with fathers' contact with nonresidential children. Close mother and maternal grandmother bonds reduce the likelihood that fathers live with their children, whereas close ties between fathers and paternal grandmothers increase the chance that fathers visit nonresidential children. Family ties do not affect fathers' financial contributions, which are driven by men's current economic situation. These findings illustrate that father–child relationships are best understood in the context of interacting family systems.  相似文献

This qualitative, grounded theory study investigated 11 families who reported having successfully integrated into their family unit at least one older/special needs adoptee. The theory that emerged through the constant comparative methodology consisted of two categories (Decision to Adopt and Adjustment) and a core category (Developing a Sense of Family). The two categories and core category comprised a process that was informed by the Family Narrative Paradigm and culminated in the successful integration of the child or children into the existing family unit. Parental perceptions that appeared to facilitate this process included: (a) finding strengths in the children overlooked by previous caregivers, (b) viewing behavior in context, (c) reframing negative behavior, and (d) attributing improvement in behavior to parenting efforts.  相似文献

The author, a professor in the field of communication, describes his contrasting experiences with publishing an open access society journal and advising a regional association in regards to turning over publication of its journal to a major commercial publishing firm. Using his experience of producing an open access journal as a foundation, he argues for the intrinsic importance of establishing credibility and exercising personal care in the production and maintenance of a journal. The author argues that current efforts by some societies to increase access to their journals through outsourcing to commercial publishers may be counterproductive to the fundamental goal of disseminating knowledge.  相似文献

Although burnout in the helping professions is well documented, few studies have examined the phenomenon of the resilient therapist. This study used a grounded theory methodology to construct a theory of therapist resilience. The participants were eight licensed marital and family therapists: five females, three males, all Caucasian, with an average age of 58.9 and an average of 22.6 years of experience who reported feeling energized by the practice of therapy. The theory that was constructed included a central category (Integration of Self with Practice), a paradigm (Trust in Self), and two main categories (Career Development and Practice of Therapy). The process involved an initial calling, a positive agency experience, career corrections, the influence of relationships, and a move to a more flexible environment.  相似文献

Abstract

Objective: To develop an instrument that measures the social context of hookah use among college students. Participants: A pool of 50 potential items, based on 44 in-depth interviews with regular college hookah smokers, was administered to a sample of 274 hookah users between October and December 2011. Methods: Participants were approached in hookah bars and asked to complete the survey. Results: A principle components analysis revealed 3 reliable factors: social facilitation, family/cultural influence, and alternative to smoking cigarettes and drinking. These were examined across different categories of hookah use: Weekly hookah users were more likely to smoke in a context of social facilitation than the other 2 groups. Similar effects were observed for family/cultural influence. Asians were more likely to smoke in a context of family and cultural influence than non-Asians. Conclusions: This scale has potential for identifying situation-specific contexts of hookah use that may help in designing effective interventions for college students.  相似文献
