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

The case of seven urine samples collected for anti-doping purposes during a cycling stage race with moderately elevated testosterone and epitestosterone ratio (T/E) is reported. The very low probability of having all seven urine samples with such similar elevated T/E ratio (from 3.2 to 4.7) was very suspicious. Different pattern classification tools were tested to categorize the most similar steroid profiles, but none of the models enabled a clear classification of the different urine samples. Subsequently, genetic profiling of all urine samples was performed and demonstrated that three of the seven samples were collected from the same cyclist. Finally, the International Federation confirmed DNA profiling results. This suggests that urinary steroid data using several methodologies are not appropriate for identification purposes and to an extent not unique to individuals. 相似文献

Conclusion This paper has attempted to analyze the effect of the development of the financial sector, as reflected by the extent of financial
deepening, in the economic development of countries. The Theoretical framework integrating financial growth to real growth
is basically an adaptation of the Gurley-Shaw theory of finance in the development context, but with emphasis placed upon
the supply-leading role of the financial sector.
The empirical results of this study although not conclusive, indicate that financial deepening leads to a higher rate of capital
accumulation and a higher level of per capita income. The lack of definitiveness of our evidence in support of the financial
theory of economic development is due to a lack of comparable data on financial institutions, other than banks, for the different
countries. Thus, although our study lends support to the supply-leading thesis, further judgement of the thesis must await
more detailed empirical analyses. 相似文献

Initial reports of domestic violence are generally made to law enforcement officers who must respond and intervene. A subset of these episodes involves cases in which the victim, and, in many instances her child(ren), have been taken hostage by her husband or partner. Moreover, there are indications that the number of such incidents is growing. The purpose of this project was twofold: (1) to provide one of the first reports on the prevalence and characteristics of these events, and (2) to more closely analyze domestic crisis (hostage) situations using actual case examples. All information was obtained from the Hostage Barricade Database System (HOBAS) of the FBIs Crisis Negotiation Unit. HOBAS is a postincident information collection tool which stores historical data from law enforcement agencies across the nation on hostage/barricade incidents. An examination of this database yielded different types of domestic hostage-taking acts and outcomes (e.g., tactical vs. negotiated resolutions, survival vs. death/injury of perpetrator and/or victim[s]). Implications of the findings, for future crisis negotiation efforts directed toward nonviolent resolution of these high-risk critical incidents, are discussed. 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

ABSTRACT According to the nationalisation hypothesis, it is sometimes argued that electoral lists competing at local elections under a national party label are more likely to win. Yet, in many countries, local lists are still much present. This article seeks to assess the attractiveness of local and national list labels at local elections. Following Rokkan’s hypothesis of the nationalisation of local politics, we test the role of socio-economic inequality on the success of electoral lists across local polities. Based on an original dataset distinguishing the labels of 1.012 electoral lists – be they local, mixed or national – in the 262 Walloon municipalities in Belgium, the multilevel regression demonstrates that local and mixed labels present a significant electoral advantage vis-à-vis national party labels. However, the article shows that this electoral gain decreases as economic inequalities increase: national labels, especially left-wing parties, attract more voters as inequalities rise. 相似文献

Previously unexamined material from two archives of the Greek (Rum) Orthodox community in Jerusalem shed new light on our understanding of the dynamic of an important segment of the city during the transition period between the Ottoman Empire and the British Mandate eras. We use these unexplored records to question communal affiliations, transitions of identity, the impact of modernity as well as notions of sacred space. We offer unique insight regarding the Christian Orthodox denomination in the city by examining its two main sub-communities, Palestinians and Greeks, and exploring the connection between the community and the city. We argue that the proximity to the holy sites bears little impact on private Christian life. We trace the impact of modernity through the change of professions and argue that the most important divide in the community was not between the ethnic groups but between the older and younger generations. Naming patterns (prosopography) disclose other influences of modernity. We contend that a seemingly minor change in naming patterns is indicative of two important processes: the secularization of the community and rising Palestinian nationality. 相似文献

Wealth-transfer taxes are federal and state levies on the valueof estates, inheritances, and gifts. Because the federal governmentallows a limited tax credit, repeal of the federal tax has implicationsfor state governments. This article discusses the economic justificationof taxing wealth transfers and provides data on the importanceof the tax from 1977 to 1997. We measure the degree of variationin the use of the tax among the states and pinpoint those statesfor which death taxation is most important. Wealth-transfertaxation needs reform but, repeal of the federal tax is inappropriate.Instead, the state levies should be abandoned. We conclude byproposing to repeal the state taxes and reduce the federal taxby an amount equivalent to the value of the federal tax-credit.The resulting revenues, however, would not to be garnered bythe federal government but returned as revenue-sharing fundsto the resident state of the decedent. 相似文献

Developing a strategy to characterize the odor prints of individuals should be relevant to support identification obtained using dogs in courts of justice. This article proposes an overview of the techniques used for the forensic profiling of human odor. After reviewing the origin of human odor—both genetic and physiological—the different analytical steps from sample collection to statistical data processing are presented. The first challenge is the collection of odor, whether by direct sampling with polymer patches, cotton gauze, etc., or indirect sampling with devices like Scent Transfer Unit. Then, analytical techniques are presented. Analyses are commonly performed with gas chromatography coupled with mass spectrometry. As they yield large amounts of data, advanced statistical tools are needed to provide efficient and reliable data processing, which is essential to give more probative value to information. 相似文献

This study explores the existence and predictive ability of a behavior-based typology of men who were adjudicated for a domestic
violence crime in an urban criminal justice system. Data from 671 men who completed a 2-hour biopsychosocial assessment were
analyzed using cluster analysis. Findings indicate a typology of low level criminality (25.6%), dysphoric volatile behavior
(42.2%), and dysphoric general violence (32.2%) similar to previous typologies, but with some unique characteristics. The
behavior-based typology predicted both program completion and subsequent rearrest. This study provides preliminary support
for the development of typological assessment in criminal justice and BIP settings for early identification of men who may
need additional interventions. 相似文献
