Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined
cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble
over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation
via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure.
Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure
sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling
cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue
exposure should be studied further as a potential tool in the treatment of problem gambling. 相似文献

OBJECTIVE: Maryland became the first state to pass a vaccination law requiring college and university students living on campus to obtain a meningococcal vaccination or to sign a waiver refusing vaccination because college students are at increased risk for disease. The authors sought to identify how Maryland colleges addressed the law and determine whether schools were in full compliance. PARTICIPANTS: The authors surveyed 32 college/university administrators via a self-administered questionnaire. METHODS: The authors calculated vaccination and waiver rates and assessed compliance with the law overall and with specific law components. RESULTS: Among 28 participating schools, annual vaccination rates and waiver rates among students during 2000-2004 ranged from 66%-76% and 12%-17%, respectively. Two (7%) schools were compliant with all components of the law. CONCLUSIONS: Mandatory vaccination laws do not ensure compliance at the college and university level. Mandatory reporting, increased education, and collaboration between colleges and universities and public health agencies are needed. 相似文献

Demographic studies indicate a remarkable aging trend in North America. An accurate profile of the decline in physical and cognitive capabilities over time is essential to our understanding of the aging process. This study examined the maintenance of skilled performance across the careers of 96 professional golfers. Data were collected on scoring average, driving distance, driving accuracy, greens in regulation, putts per round, and number of competitive rounds played using online data archives. Analyses indicate that performance in this activity can be maintained to a greater extent than in activities relying on biologically constrained abilities. Although the generalizability of these results to "normal" aging populations is not known, they suggest that acquired skills can be maintained to a large extent in the face of advancing age. 相似文献

This paper reviews the main bodies of contemporary urban sustainability theory. From this analysis, two underpinning paradigms
of urban sustainability are identified: (1) The ‘Human Exemptionalism Paradigm’ (HEP), which emphasizes the ability of humans
to overcome environmental problems—see Urban Sociology, Urban Ecology, Urban Geography, Urban Psychology and Political Economy;
and (2) The ‘New Ecological Paradigm’ (NEP), which emphasizes the criticality of ecological limits to human progress—see Urban
Metabolism, Energy/Emergy Analysis and Ecological Footprinting. Each of these approaches is critically reviewed, highlighting
their main assumptions, theoretical and practical foci. It is argued in the paper that if the related issues of urban sustainability
and development are to be progressed, there needs to be: (1) a greater maturation of the NEP approaches, which are ‘relative
newcomers’ to the area of urban theory; and (2) greater integration and dialogue between the HEP and NEP approaches to urban
sustainability than has hitherto been the case.

Employee assistance professionals are expected to be proficient at intervening in organizations and creating meaningful behavioral change in interpersonal functioning. Because of their training in family systems theories and concepts, marriage and family therapists (MFTs) are well suited to serve organizations as "systems consultants." Unfortunately, the authors were unable to identify any family systems-based models for organizational intervention that have been empirically tested and supported. In this article, the authors present a family systems-based model of intervention that they developed while working in an employee assistance program (EAP). They also present research that was used to refine the model and to provide initial support for its effectiveness. 相似文献

Video recording provides an objective record of the content of medical interactions. However, there is concern that cameras
may be reactive measurement devices that alter what normally transpires during interactions. This study addressed potential
reactivity of cameras in medical interactions. Interactions between 45 patients and 14 medical oncologists were video recorded
and coded for camera-related behaviors. Eleven of 45 patients performed none of the behaviors. Among the other patients, camera-related
behaviors were infrequent and, on average, constituted about 0.1% (one-tenth of one percent) of total interaction time. Behaviors
occurred most often in very early stages of interactions, and when physicians were absent from the room. Seven physicians
showed camera-related behaviors, comprising less than 0.1% of the time they were in the interaction. Results suggest video
recording can provide nonreactive means of studying medical interactions.

This article presents an efficient way of dealing with adaptive expectations models—a way that makes use of all the information available in the data. The procedure is based on multiple-input transfer functions (MITFs): by calculating lead and lag cross correlations between innovations associated with the variables in the model, it is possible to determine which periods have the greatest effects on the dependent variable. If information about k periods ahead is required, fitted values for the expectation variables are used to generate k-period-ahead forecasts. These in turn can be used in the estimation of the transfer function equation, which not only contains the usual lagged variables but also allows for incorporation of lead-fitted values for the expectation variables. The MITF identification and estimation procedures used are based on the corner method. The method is contrasted with the Almon distributed-lag approach using a model relating stock market prices to interest rates and expected corporate profits. 相似文献
