An exploratory outcome study to investigate the ability of a supervised access and custody exchange center to function as a safe visitation enforcement mechanism of the court was accomplished as part of a larger study investigating child well-being. During a 6-month period of program participation, frequency and consistency of noncustodial parents' access to children dramatically increased and interparental conflict significantly decreased, demonstrating that supervised visitation and custody exchange centers that function in partnership with family court during interim court processes can address the unmet needs of family court and high-conflict domestic disputant as well. 相似文献

Corrosion of α‐phase brass by sebaceous sweat fingerprint deposits produced identifiable impressions in a majority of samples (n = 40) 4 days after deposition. Combining sebaceous with eccrine sweat yielded a greater percentage of identifiable fingerprint deposits, although this increase was not statistically significant. Production of identifiable fingerprints from eccrine sweat deposits was dependent on the sampling time of year with deposits taken during summer months giving similar percentages of identifiable fingerprints to sebaceous deposits. A statistically significant positive correlation was found between elapsed days after deposition and identifiable eccrine (ρ = 0.787, p < 0.05), sebaceous (ρ = 0.724, p < 0.05), and eccrine/sebaceous mixture (ρ = 0.908, p < 0.01) fingerprints deposited during summer months. The summer increase in the percentage of identifiable eccrine sweat deposits was statistically significant compared to winter eccrine deposits (p < 0.0001). Observations were consistent with results obtained from artificial sebaceous and eccrine sweat. 相似文献

“Bath salts” are synthetic derivatives of cathinones, compounds found in the leaves of Catha edulis, which possesses amphetamine‐like properties. At the New York City Office of Chief Medical Examiner, we conducted a 3‐year retrospective analysis of deaths in which cathinones were detected. Two categories emerged; those in which cathinones were a contributory cause of death (15 cases) and those in which they were an incidental finding (15 cases). Of the former group, 13 were associated with additional intoxicants; two deaths were attributed solely to cathinone intoxication, both survived 10 h: a man whose postmortem blood methylone concentration was 0.71 mg/L and a woman whose postmortem blood ethylone concentration was 1.7 mg/L. In the latter category, there were several individuals who had higher concentrations of cathinones than the above two, the highest being a blood methylone of 4.8 mg/L. Based upon our data and the literature presented, lethal concentrations of cathinones cannot be established. 相似文献
