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

Using original data from client-community assessments, we examine motivations in the Ugandan NGO sector. In general, client-community satisfaction with NGO interventions is high, even though some NGO staff are viewed as unresponsive, underskilled, or self-serving. We find evidence that NGOs endeavour to redress the balance between rich and poor, although more remote communities suffer neglect, possibly for cost reasons. NGOs are less inclined to maintain a permanent presence in more remote and poorer client-communities, which impacts negatively on their assessment scores. We also find evidence that NGOs too often operate in the same location, resulting in some duplication of effort. Finally, results indicate that community participation enhances satisfaction.  相似文献

A 43‐year‐old full‐term pregnant woman (gravida 2, para 1, medical history of gestational diabetes mellitus) developed a sudden and malignant hypertension with hemoptysis, sweat, and tachycardia during a scheduled C‐section. A dead newborn was delivered and was successfully resuscitated. The mother died after resistant cardiac arrest. Autopsy and pathological analyses revealed an acute pulmonary edema and a necrotic and hemorrhagic voluminous tumor of the left adrenal gland, which was a pheochromocytoma. Pheochromocytoma is a rare tumor of the adrenal glands which secretes catecholamines. In pregnant women, its symptoms can mimic gestational hypertension, preeclampsia or eclampsia, and gestational diabetes mellitus. The gestational diabetes mellitus was presumed to be a symptom of the pheochromocytoma, and cardiopulmonary failure the result from the necrosis of the tumor provoked by gravid uterus compression. From a medico‐legal point of view, the tumor could not have been suspected during the pregnancy.  相似文献

Abstract:  Information on gunshot wound characteristics has been well documented; however, there is little documented information on the effects of decomposition or environmental conditions on gunshot wound characteristics. This study was conducted in order to determine if decomposition would obscure or alter the physical surface characteristics of gunshot wounds when exposed to a low temperature environment. The study was conducted from November 2005 to January 2006 in Nova Scotia, Canada in forested and exposed environments, with air temperatures between −10°C and +10°C. Pigs were used as human models and were shot six times each at three different ranges (contact, 2.5 cm, and 1.5 m). Gunshot wound characteristics persisted until the wounds were covered with ice and snow, after which changes were observed. The changes were recognized as being unique to the different ranges of gunshots and it was concluded that changes due to decomposition under the conditions tested would not affect the collection and interpretation of gunshot wound evidence.  相似文献

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used.  相似文献

Testing for drugs in hair raises several difficulties. Among them is the interpretation of the final concentration(s). In a post‐mortem case, analyses revealed the presence of furosemide (12 ng/mL) in femoral blood, although it was not part of the victim's treatment. The prosecutor requested our laboratory to undertake an additional analysis in hair to obtain information about the use of furosemide. A specific method was therefore developed and validated to identify and quantify furosemide in hair by UHPLC‐MS/MS. After decontamination of 30 mg of hair, incubation in acidic condition, extraction with ethyl acetate, the samples were analyzed by UHPLC‐MS/MS. Furosemide was found in the victim's hair at 225 pg/mg. However, it was not possible to interpret this concentration due to the absence of data in the literature. Therefore, the authors performed a controlled study in two parts. In order to establish the basis of interpretation, several volunteers were tested (four after a single 20 mg administration and twenty‐four under daily treatment). The first part indicated that a single dose is not detectable in hair using our method. The second part demonstrated concentrations ranging from 5 to 1110 pg/mg with no correlation between dosage and hair concentrations. The decedent's hair result was interpreted as repeated exposures. In the case of furosemide analysis, hair can provide information about its presence but cannot give information about dosage or frequency of use.  相似文献

Staff ratings of 595 supervised forensic psychiatric patients on the Proximal Risk Factor Scale and the Problem Identification Checklist were completed monthly for an average of 33 months. During the follow-up, there were 265 incidents, 86 of which were violent. The average ratings, excluding those from the index month, differentiated patients who had incidents from those who did not. As well, the average ratings distinguished between individuals with and without incidents of a violent or sexual nature. There were significant increases in staff ratings in the months preceding the index incident month. Within-patient analyses showed that changes in dynamic risk scales comprising the best items for predicting incidents of any kind and violent or sexual incidents were strongly related to their respective outcomes and were significantly related to outcome in an independent sample. Changes in monthly staff ratings predict the imminent occurrence of antisocial and violent behaviors.  相似文献

In Northern Ireland there are many fewer permanent exclusion from school than in England and Wales. It has been suggested that this may be linked to differences in the statutory schemes which regulate exclusion. This article compares the legal framework for school exclusions in Northern Ireland and England and Wales; provides a comparative analysis of the statistical data in relation to school exclusions; assesses whether the differences in the legal framework may have an impact on the propensity to permanently exclude; and considers whether there are any other non-legal factors which may explain lower rates of school exclusions. The overall objective is to see whether the legal differences which exist have a meaningful effect on the overall rate of school exclusion and to extrapolate best practice. In particular, the analysis focuses on experience of the statutory pre-expulsion consultation procedure in Northern Ireland, which has no equivalent in England and Wales.  相似文献
