We review the history of gaming and its taxation in the U.S., particularly in regard to the idea of “sin taxes” which were often presented as policy instruments intended to control problem gamblers. The review suggests that raising taxes neither encourages moderation nor replaces negative external costs. We follow the review with a socioeconomic impact analysis of a proposed four percent Federal Gaming Tax by simulating its impact on Clark County, Nevada for the period 1995-2004 using a large scale econometric multi-regional model. Clark County is of interest because it is where Las Vegas is located. The analysis reveals that the proposed tax would lead to a measurable decline in Clark County's jobs, population, disposable income, and total industrial during the forecast period. By 2004, total industrial output would be 1.3 percent lower under the proposed tax and Clark County would experience a loss of $1.39 in real disposable income for every gaming tax dollar collected by Federal Government. These reductions, coupled particularly with the loss of thousands of jobs in Las Vegas area hotels/casinos predicted by the analysis suggest that increased demands on social services in Clark County would result. These findings, together with the lack of evidence that raising taxes would promote moderation or reduce external negative costs, lead us to argue that excise taxes represent an unattractive option.  相似文献

E-cigarette taxes are an active area of legislation and have important regulatory implications by proxying e-cigarette accessibility. We examine the effect of e-cigarette taxes on prepregnancy and prenatal smoking using the near-universe of births to mothers conceiving between 2013 and 2019 in the United States. Using fixed effect regressions, we show that e-cigarette taxes increase prepregnancy and prenatal smoking. We also find evidence that e-cigarette taxes reduce prepregnancy and 3rd trimester e-cigarette use. Finally, we show that e-cigarette taxes increase news coverage of e-cigarettes and raise perceptions of risk of e-cigarettes.  相似文献

In the light of the increasing political influence on German universities (amongst others, the excellence initiative) with effects on the selection of top positions, this article examines the appointment of chairs (department heads) in a “small” surgical specialty during the last 30 years. Following the delineation of official indicators of competence (inclusion criteria) within an appointment procedure, it can be shown that a broad distribution of institutions and persons that meet these criteria exists. The empirical examination of the actually successful occupations shows that closure mechanisms play a role because the successful candidates stem from no more than 10 out of 34 clinical departments. The monetary capital in terms of third-party funds is the most important allocation criterion, but cannot sufficiently explain the way appointments take place. As there are candidates who in formal terms are in a wide measure equally qualified, and a consequential uncertainty of the basis of decision within an appointment procedure, the derivation of the candidate in terms of a personal relationship to a chair holder (department head) from whose clinic he applies and who acts as a patron, proves to be the decisive distinction following the examination of all inclusion criteria. This results in a reproduction of the chair holders (department heads) largely from the same clinical departments and the formation of an academic caste system. In perspective, this cartel-like closure appears to be getting increasingly worse.  相似文献

东亚-北美经济失衡与再平衡分析   总被引:1,自引:0,他引:1  
本文从国别结构和产品结构分析了20世纪90年代以来东亚—北美经济失衡的变化,认为美国贸易逆差不断扩大是其对外产业转移的结果,东亚地区贸易顺差与日俱增是其承接产业转移的结果。其中,东亚内部再次产业转移导致中国顺差迅速膨胀。为了实现东亚—北美经济再平衡,美国需要采取一些措施扩大出口,控制过度的信贷消费,并对美元采取更加负责的政策;东亚地区需要努力实现由外需驱动型向内需驱动型增长方式的转变,加快产业调整与升级,并把产业链向其他地区延伸。  相似文献

OBJECTIVE: This study examined baseline self-efficacy as a moderator of outcomes comparing women receiving either the Women's Recovery Group (WRG), a new manualized group treatment for substance use disorders combining single-gender group composition and women-focused content, or Group Drug Counseling (GDC), an empirically supported mixed-gender group treatment. METHODS: To understand the relationship of baseline scores of abstinence self-efficacy measured by the Drug-Taking Confidence Questionnaire (DTCQ) to outcome, we included the interaction of group by phase by continuous DTCQ scores in the outcome analyses. Women were split into groups of high versus low abstinence self-efficacy based on the clinical cutoff score of 80 on DTCQ. RESULTS: We found a significant 3-way interaction effect of treatment condition, time, and baseline DTCQ scores on drinking days and days of any substance use per month. Women in WRG had greater reduction in substance use from baseline to post-treatment than women in GDC, and women in WRG with low self-efficacy had the best outcomes overall. CONCLUSION: The findings suggest that women with low self-efficacy may have enhanced treatment outcomes in a single-gender substance use treatment group.  相似文献

Group psychotherapy with disturbed undersocialized adolescents requires modification of traditional group psychotherapy methods. The effectiveness of a structured, brief video-tape feedback and discussion on group psychotherapy process with this population was studied by an analysis of detailed ratings of each statement, or process unit; in randomly selected videotapes from a control and experimental group during a nine-month period. Significant differences in level of intimacy of verbal content and in frequency of feedback about behavior in content indicate that this technique is effective in facilitating group psychotherapy goals.Received Ed.D. from University of Kentucky.

Detection of blood on dark materials is difficult for crime scene examiners so presumptive tests are used to assist. This study compared the ability of luminol, leuko crystal violet, tetramethylbenzidine, and Combur Test®E to detect whole, diluted blood (1:100) and a key‐shaped blood transfer stain (1:10), on dark cotton sheeting, tea towel, socks, synthetic carpet, and car mats. Powdered bleach was used to evaluate specificity of the blood detection tests. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall misclassification rate (OMR) assessed the quality of the blood tests. Luminol was the preferred test for diluted blood having the highest sensitivity (79%–96%), NPV (66%–93%), and the lowest OMR (3%–15%). Luminol was also found to be most efficient with a testing time on 25 items of 2 h 50 min compared with up to 8 h. Overall, luminol was the most effective method, also providing information on bloodstain patterns.  相似文献

Psychostimulant use is associated with increased stroke risk. To determine the proportion of psychostimulant users among fatal strokes in young adults (15–44 years), all cases were retrieved from the National Coronial Information System (1/1/2009–31/12/2016). A total of 279 cases were identified: hemorrhagic (259), ischemic (8), thrombotic (8), and mycotic (4). Fifty (17.9%) were identified as psychostimulant users. Psychostimulants in blood were detected in 37/45 where toxicology was available, predominantly methamphetamine (32/45). Hemorrhagic strokes in the psychostimulant group were more likely to be intraparenchymal (OR 2.33). Psychostimulant users were less likely to be obese (OR 0.31), but more likely to have a history of tobacco use (OR 2.64). No psychostimulant user had a previous stroke history, was gravid/postpartum, or diagnosed with cerebral vasculitis or endocarditis. The work illustrates the substantial role of psychostimulant use in fatal strokes among young adults. In cases of hemorrhagic stroke among young adults, psychostimulant use should be considered.  相似文献

Forensic DNA interpretation is transitioning from manual interpretation based usually on binary decision‐making toward computer‐based systems that model the probability of the profile given different explanations for it, termed probabilistic genotyping (PG). Decision‐making by laboratories to implement probability‐based interpretation should be based on scientific principles for validity and information that supports its utility, such as criteria to support admissibility. The principles behind STRmix? are outlined in this study and include standard mathematics and modeling of peak heights and variability in those heights. All PG methods generate a likelihood ratio (LR) and require the formulation of propositions. Principles underpinning formulations of propositions include the identification of reasonably assumed contributors. Substantial data have been produced that support precision, error rate, and reliability of PG, and in particular, STRmix?. A current issue is access to the code and quality processes used while coding. There are substantial data that describe the performance, strengths, and limitations of STRmix?, one of the available PG software.  相似文献
