The Electric Power Research Institute (EPRI) is a consortium of utility companies whose existence depends on member perceptions that valuable technologies and information have been developed and transferred. This paper outlines eight issues that EPRI, after 17 years of operation had determined to be critical in transferring technology: [1] establishing a perception of value received, [2] creating a sense of full partnership, [3] balancing the R&D portfolio with projects for different members, [4] packaging results for easy understanding and use, [5] reducing information overload by using targeted media, [6] assuring that members have the needed infrastructure to receive and process transfer, [7] integrating EPRI's R&D program with those of the members, and [8] monitoring impact to be sure that value is being received. 相似文献

A rapid urinalysis system based on SPE-LC-MS/MS with an in-house post-analysis data management system has been developed for the simultaneous identification and semi-quantitation of opiates (morphine, codeine), methadone, amphetamines (amphetamine, methylamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxymethamphetamine (MDMA)), 11-benzodiazepines or their metabolites and ketamine. The urine samples are subjected to automated solid phase extraction prior to analysis by LC-MS (Finnigan Surveyor LC connected to a Finnigan LCQ Advantage) fitted with an Alltech Rocket Platinum EPS C-18 column. With a single point calibration at the cut-off concentration for each analyte, simultaneous identification and semi-quantitation for the above mentioned drugs can be achieved in a 10 min run per urine sample. A computer macro-program package was developed to automatically retrieve appropriate data from the analytical data files, compare results with preset values (such as cut-off concentrations, MS matching scores) of each drug being analyzed and generate user-defined Excel reports to indicate all positive and negative results in batch-wise manner for ease of checking. The final analytical results are automatically copied into an Access database for report generation purposes. Through the use of automation in sample preparation, simultaneous identification and semi-quantitation by LC-MS/MS and a tailored made post-analysis data management system, this new urinalysis system significantly improves the quality of results, reduces the post-data treatment time, error due to data transfer and is suitable for high-throughput laboratory in batch-wise operation. 相似文献

Although there are many roadside testing devices available for the screening of abused drugs, none of them can be used for the detection of ketamine, a popular abused drug in Hong Kong. In connection to local drug driving legislation, effective roadside detection of ketamine in suspected drug-impaired drivers has to be established. According to the drug evaluation and classification program (DEC), ketamine is classified in the phencyclidine (PCP) category. However, no study has been performed regarding the signs and symptoms exhibited by users under the influence of ketamine. In a study to develop a protocol for effective roadside detection of drug-impaired drivers, 62 volunteers exiting from discos were assessed using field impairment tests (FIT) that included measurements of three vital signs (i.e. body temperature, pulse rate and blood pressure), three eye examinations [pupil size, lack of convergence (LOC) and horizontal gaze nystagmus (HGN)] and four divided attention tests (Romberg, one-leg stand, finger-to-nose and walk-and-turn tests). Subsequent laboratory analysis of oral fluid and urine samples from the participants revealed the presence of common abused drugs in both the urine and oral fluid samples of 55 subjects. The remaining 7 subjects with no drug in their oral fluid samples were used as drug-free subjects. In addition, 10 volunteers from the laboratory who were regarded as drug-free subjects were also assessed using the same FIT. Among the 62 volunteers, 39 of them were detected with ketamine in their oral fluid. Of these ketamine users, 21 of them (54%) with only ketamine found in their oral fluid samples while the rest (18 subjects) of them had other drugs (i.e. MA, MDMA, benzodiazepines and/or THC) in addition to ketamine. Of the 21 ketamine-only users, 15 of them (71%) were successfully identified by FIT. It was found that when salivary ketamine concentrations were greater than 300 ng/mL, signs of impairment became evident, with over 90% detection rate using the FIT. By comparing the FIT observations on the 21 ketamine-only users with the drug-free subjects, the typical signs and symptoms observable for subjects under the influence of ketamine included LOC, HGN, elevated pulse rate and in general, failing the divided attention tests, especially the walk-and-turn and one-leg stand. 相似文献

Although proprietary medicines and decoction of processed aconite roots are the most widely used, tincture accounts for the great majority of aconite poisoning cases in China, indicating that it is much more toxic than other formulations. Aconite tincture is often self-prepared at home and raw aconite plants or roots are often used. Even if processed aconite roots were used to make the tincture, the amount of Aconitum alkaloids is highly variable, depending on the adequacy of processing and quality control. Aconitum alkaloids dissolve efficiently in alcohol. For these reasons, tincture contains very high concentrations of Aconitum alkaloids. Despite its high intrinsic toxicity, overdose of aconite tincture by the users has been common. Severe aconite poisoning can be complicated by fatal ventricular tachyarrhythmias and asystole. The public should be repeatedly warned of the danger of taking aconite tincture by mouth. 相似文献

The present study reports the development and validation of the Chinese Risk Assessment Tool for Victims (CRAT-V), an actuarial
instrument for the prediction of intimate partner violence (IPV) victimization in a Chinese population. Data were collected
from a representative sample of 2,708 Chinese women who were married or cohabiting in Hong Kong. All participants were interviewed
with a questionnaire assessing their experience of IPV victimization and personal or family factors related to IPV. As measured
by the Revised Conflict Tactics Scale (CTS 2), the base rates of preceding-year physical and sexual IPV victimization were
4.6 % and 3.6 %, respectively. Using a cross-validation procedure, the present study developed a 5-factor instrument with
one half of the randomly split sample and validated the resulting tool with the other half. The CRAT-V had a sensitivity of
74.0 %, a specificity of 68.3 %, an overall accuracy of 68.7 %, and an area under the receiver operating characteristic (ROC)
curve of 0.75 when administered on the second half of sample. Overall, the CRAT-V may serve as a straightforward, systematic,
and easy-to-administer instrument tailor-made for Chinese populations for the assessment of risk of IPV victimization against
women. 相似文献

Recent evidence of the prevalence of stress and mental health issues among Australian lawyers has led to calls for legal culture to be changed to promote a better work–life balance and wellbeing for practitioners. Yet three decades of empirical studies in North America have shown consistently high levels of job satisfaction among lawyers. This paper investigates the role of legal culture in sustaining the paradox of satisfied lawyers under working conditions that may be conducive to stress. Drawing on Bourdieu's theory of practice and the literature on work stress, the paper conceptualises the relationships between the demand of legal work, the culture of legal practice, and lawyering stress. It concludes with a discussion of the implications of this kind of analysis for reforming the legal profession. In spite of the difficulty of cultural change, the paper argues that as consciousness is raised and the field changes, alternative models of practice will need to emerge, so that lawyering stress may become a mechanism for change not reproduction. 相似文献

Angle grinders are one of the most dangerous and frequently used tools in industrial settings. Angle grinder injuries range from superficial cuts to deep penetrating injuries with underlying fracture-dislocation and vascular trauma. The injuries caused by angle grinders mostly involve the head, face, or upper limbs, while the lower limb is an unusual site. The high-speed rotating disc of the angle grinders does not respect anatomical boundaries or structures; therefore, the injuries caused may be disfiguring, permanently incapacitating, or even fatal. We report a fatal case of an angle grinder injury to the lower limb. The victim sustained a sharp cut over the left thigh while woodworking in an industrial setup. The rotating disc of an angle grinder had transected the skin, subcutaneous fat and muscles, and both the femoral vessels of the left side, which led to fatal exsanguination within 10 min of the incident. 相似文献
