This study suggests that rural reigonal councils have greater support among public officials for continuing current program activities and services than their urban counterparts. It also suggests, however, that rural regionalism may have a better chance of survival in states where regional councils have a long history of service to local governments, especially in light of present federal cutbacks. Study results contrast Georgia and Michigan regional councils.  相似文献

There have been reports on improved chromatographic parameters derived from the incorporation of sequential derivatization in preparing biological specimens for the analysis of opiates. This current study was designed to characterize the mass spectrometric data resulting from sequential derivatizations of commonly abused amphetamines (along with all commercially available deuterated analogs) containing two active sites, i.e., amphetamine, methylenedioxyamphetamine, phenylpropanolamine. The first derivatization groups included in this study were trifluoroacetyl, pentafluoropropionyl, and heptafluorobutyryl, while t-butyldimethylsilyl was used as the second derivatization group. Products resulting from the first step and the two-step derivatization processes were analyzed by GC-MS. Full-scan mass spectrometric data were used to select ions with potential for designating the analytes and their respective isotopically labeled analogs in quantitative analysis protocols. Selected ion monitoring data were then collected and assessed to determine the quality of these ions when one or two different derivatization groups were incorporated in the sample preparation processes. A total of 77 full-scan mass spectra and 8 ion intensity cross-contribution tables, representing various forms of derivatization and isotopic analogs of the three amphetamines, are systematically presented for reference. Evaluations of these data concluded that many, but not all, products derived from "double derivatization" (sequential derivatization with two derivatization groups), generate ions of higher quality than those derived from "single derivatization".  相似文献

Childhood abuse and other developmentally adverse interpersonal traumas may put young adults at risk not only for posttraumatic stress disorder (PTSD) but also for impairment in affective, cognitive, biological, and relational self-regulation ("disorders of extreme stress not otherwise specified"; DESNOS). Structured clinical interviews with 345 sophomore college women, most of whom (84%) had experienced at least one traumatic event, indicated that the DESNOS syndrome was rare (1% prevalence), but DESNOS symptoms were reported by a majority of respondents. Controlling for PTSD and other anxiety or affective disorders, DESNOS symptom severity was associated with a history of single-incident interpersonal trauma and with more severe interpersonal trauma in a dose-response manner. Noninterpersonal trauma was associated with elevated prevalence of PTSD and dissociation but not with DESNOS severity. Study findings indicate that persistent posttraumatic problems with self-regulation warrant attention, even in relatively healthy young adult populations.  相似文献

A simple and rapid method for the analysis of heroin seizures by micellar electrokinetic chromatography with short-end injection is described. Separations were performed using an uncoated fused silica capillary, 50 cm x 50 microm I.D. x 360 microm O.D. with an effective separation length of 8 cm. The system was run at 25 degrees C with an applied negative voltage of -25 kilovolts. Injection of each sample was for 2 s at -50 mbar. UV detection was employed with the wavelength set at 210 nm. The background electrolyte consisted of 85:15 (water:acetonitrile, v/v) containing final concentrations of 25 mM SDS and 15 mM sodium borate, pH 9.5. Samples and standards were prepared in 0.1% v/v acetic acid and diluted in the run buffer containing 1 mg/ml of N,N-dimethyl-5-methoxytryptamine as an internal standard. Under these conditions a text mixture containing caffeine, paracetamol, morphine, codeine, heroin, and acetylcodeine was resolved within 1.5 min. The method was used to determine the concentration of heroin in heroin seizure samples, and the results were in good agreement with those obtained by a validated gas chromatographic method.  相似文献

Forensic mitochondrial DNA analysis of 691 casework hairs   总被引:1,自引:0,他引:1  
A five year retrospective review of mitochondrial DNA (mtDNA) analysis on 691 casework hairs was carried out. A full or partial mtDNA profile was obtained for > 92% of hairs. With increasing age of the hair, the likelihood of obtaining a full profile decreased, although "mini-primer sets" could often be used to capture a partial profile. With increasing color and diameter of the hair, the likelihood of obtaining a profile increased. Full or partial profiles were obtained on more than 80% of 114 hairs < or = 1.0 cm. Mixtures were observed in 8.7% of hairs tested; mixtures increased with the age of the hair and were presumed to be due to exterior surface contamination that could not be sufficiently cleaned prior to extraction, since the overall level of laboratory contamination was low. The frequency of sequence heteroplasmy was 11.4%, and both hot-spot and novel sites were observed. In about one-third of these observations, another sample in the case showed either the same heteroplasmic site or a nucleotide substitution at that site.  相似文献
