The relative toxicity of ephedra-containing dietary supplements is disputed. In order to ascertain the magnitude of the problem, we reviewed all autopsies in our Medical Examiner's jurisdiction, from 1994 to 2001, where ephedrine or any its isomers (E+) were detected. Toxicology testing results were tabulated and anatomic findings in E+ cases were compared to those in a control group of drug-free trauma victims. Of 127 E+ cases identified, 33 were due to trauma. Decedents were mostly male (80.3%) and mostly Caucasian (59%). Blood ephedrine concentrations were <0.49 mg/l in 50% of the cases, range 0.07-11.73 mg/l in trauma victims, and 0.02-12.35 mg/l in non-trauma cases. Norephedrine (NE) was present in the blood of 22.8% (mean of 1.81 mg/l, S.D.=3.14 mg/l) and in the urine of 36.2% (mean of 15.6 mg/l, S.D.=21.50mg/l). Pseudoephedrine (PE) was present in the blood of 6.3% (8/127). More than 88% (113/127) of the decedents also tested positive for other drugs, the most common being cocaine (or its metabolites) and morphine. The most frequent pathologic diagnoses were hepatic steatosis (27/127) and nephrosclerosis (22/127). Left ventricular hypertrophy was common, and coronary artery disease (CAD) detected in nearly one third of the cases. The most common findings in E+ deaths are those generally associated with chronic stimulant abuse, and abuse of other drugs was common in those with CAD. There were no cases of heat stroke or rhabdomyolysis. In most cases, norephedrine was not detected, suggesting it plays no role in ephedrine toxicity. 相似文献

Inmates with mental health and co-occurring mental health and substance use disorders present difficult challenges for correctional institutions and treatment providers. The complex nature of co-occurring disorders further exacerbates these difficulties and is associated with poor treatment compliance and increased likelihood of engaging in institutional misconduct. The current study examines whether exposure to prison-based treatment reduces involvement in prison misconduct among a sample of female prison inmates controlling for disorder types (i.e. mental health disorder only, substance use disorder only, and co-occurring mental and substance use disorders). Findings revealed that with exposure of more than 181?days of treatment, the odds of misconduct involvement among females with co-occurring disorders more than doubled compared to receiving no treatment. This finding is at odds with treatment retention literature that suggests that a minimum period of time in treatment is needed to affect post-treatment success. Possible explanations for these findings and policy implications are discussed. 相似文献

This paper examines the static consequences of transport costs in low‐income agricultural economies, and argues that many phenomena common to such economies may be largely due to the costs of transportation. It is argued below that the coexistence of ‘modern’, intensive capital‐using farms and others using primitive, extensive farming methods and very little capital can be a response to transport costs. It also seems possible that a sizeable fraction of the frequently observed urban‐rural wage gap may be a transport‐related index number phenomenon rather than a true gap in real wages. 相似文献

One of the most consistent themes among contemporary administrative theorists is that the workplace of the future will be a more hospitable environment for public workers than is currently the case. Decentralization, participative management, and intrinsically satisfying work are commonly forecast. Using survey data from state employees, this study identifies a large class of civil servants that has not yet, and probably will not, enjoy the enriched jobs that are so often predicted. The discussion identifies a number of factors in the work environment of these workers that are likely to frustrate attempts to make their jobs more meaningful and pleasant. Having acknowledged their existence and assessed their plight, the study concludes with a summary of measures that can be taken to address the needs of these “forgotten workers.” 相似文献

The complexity of the personnel performance appraisal process prompts the authors to label it the “missing link” in human resource management. Three major purposes or uses of appraisals are identified--motivation, information and development. In addition, four key factors are examined which influence the success of appraisals: (1) the timing of them; (2) the selection of the evaluator; ( 3 ) the variables used for evaluation; and (4) the appraisal technique used. Seven techniques are analyzed and shown to be different in their optimum uses. Addit- ional pitfalls are identified, based upon a thorough literature search, which are categorized into three separate categories: instrumental, evaluator and environmental pitfalls. The problems with the processes and techniques of employee performance appraisals are then examined in the light of the implications they raise for basic societal values such as the merit system, productivity and bureaucratic responsibility. Without drastic revision, the utility of appraisals is subject to challenge. Thus, this important technique of personnel administration threatens to remain the “missing link” in human resource management. 相似文献

AbstractA quarter century ago, in 1951–53, while trying to end the Korean war, the Truman and Eisenhower administrations struggled to keep Syngman Rhee, the president of the Republic of Korea [ROK] , from undermining the negotiations, wrecking the armistice, endangering the United Nations forces, and extending the war. Often it was unclear whether or not he would abide by the armistice and whether or not he would leave the ROK troops under the UN Command, or imperil the UN forces by withdrawing his own. General Mark Clark, the American and United Nations commander in the last year of war, aptly summarized the problems, “I found myself engaged in a two-front diplomatic battle ... with the ... Communists and with ... Rhee [, and] the biggest trouble came from Rhee.” As Rhee's price for acceding to the armistice of July 27, 1953, he secured from the Eisenhower administration generous economic aid, continued military assistance, and a mutual defense treaty, which has endured to the present. Before the armistice, however, military and political leaders in both administrations seriously considered toppling Rhee and installing a more tractable government. 相似文献
