Roadside detection of impairment under the influence of ketamine--evaluation of ketamine impairment symptoms with reference to its concentration in oral fluid and urine

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.     

Family Violence and Children’s Behavior Problems: Independent Contributions of Intimate Partner and Child-Directed Physical Aggression

Using data from a diverse sample of 581 families living in predominantly low-income, rural communities, the current study sought to investigate the longitudinal associations among father-perpetrated intimate partner violence (IPV) and child-directed physical aggression perpetrated by the mother. The unique contributions of each of these types of family violence on children’s behavioral problems at school entry were also examined. Results confirm bidirectional associations between father-perpetrated IPV and maternal physical aggression directed toward the child, and indicate that both types of physical aggression contribute to child behavior problems at school entry.     

The attractiveness of local and national list labels: the role of socio-economic inequalities on the success of electoral lists

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.     

Matrimony and baptism: changing landscapes in Greek (Rum) Orthodox Jerusalem (1900–1940)

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.     

Policy Transfer and Policy Learning: A Study of the 1991 NewZealand Health Services Taskforce

Research into policy transfer and lesson drawing has been criticized asfew authors have convincingly shown how cross-national policy learning actually influences policy formation in a particular jurisdiction. This article addresses this gap by presenting a study of the development of the 1991 health policy in New Zealand. By studying the process of policy development, rather than just a policy document, it was possible to disaggregate different aspects of the policy and to identify sources and influences. This article finds that the 'conspiracy' model of policy formation does not fit this case as it presents an overly simplistic view, which allows little space for policy learning. This case illustrates the subtle and multifaceted influence of different jurisdictions, different institutions, and different individuals on a given policy.     

Wealth-Transfer Taxes in U.S. Fiscal Federalism: A Levy Still in Need of Reform

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.     

SARSCOV-19 amidst corruption: Does the civil society matter? – An empirical study

The pandemic outbreak has dealt consequences on global engagements and structures. With the ongoing search for pandemic-mitigating measures and the excesses (notably corruption) erupted in its wake, concerns have been raised about the decline in public trust, transparency and satisfaction – particularly in Ghana. This situation has spurred multilevel governance discussions regarding pandemic management. Ensuingly characterising policy makers' propositions in this regard is the civil society's salience as a control valve to governance deficits like corruption. Therefore, transcending the anecdotal claims on civil society's efficacy, this study takes a state-society perspective to probe its relevance in fostering trust, transparency and satisfaction, relative to corruption-stricken pandemic governance. The current study engages the general systems theory as a conceptual lens. The structural equation modelling technique was used in analysing data (n = 519) gathered through the questionnaire survey approach. Though results of data analysis affirmed the negative effects of corruption on trust, transparency and satisfaction, the civil society received affirmation as an enhancer of trust, transparency and satisfaction. In view of these study findings, implications and future research suggestions are delimited.     

Breaking the glass ceiling,but facing a glass cliff? The role of organizational decline in women's representation in leadership positions in Dutch civil service organizations

Despite efforts to increase gender diversity and equality worldwide, women are still underrepresented in leadership positions in public bureaucracies. This article speaks to the debate on how organizational context, more specifically organizational decline, may influence gender representation in such leadership positions. Based on role congruity theory and glass cliff theory this article empirically examines whether and how excessive workforce reductions are associated with changes in the representation of women in leadership positions in Dutch civil service organizations. Panel analyses on administrative data show that women's representation in leadership positions varies over time, but is not significantly affected by excessive workforce reductions. Overall, the analyses do not provide evidence for a glass cliff for women in Dutch civil service organizations. Implications for theory and future research are discussed.     

Origin,Analytical Characterization,and Use of Human Odor in Forensics

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.     

What is grievance thinking and how can we measure this in sexual offenders?

Purpose. This study proposes and examines a three‐stage model of the grievance process, one of the dynamic risk factors related to risk of sexual recidivism, and aims to evaluate some of the existing measures of this construct. Methods. The research used a sample of 322 male sexual offenders who had completed a cognitive–behavioural programme that aims to reduce recidivism in higher‐risk sexual offenders (as measured using a static actuarial tool). Participants completed two questionnaires measuring aspects of grievance thinking pre‐ and post‐treatment. Results. The results indicated some support for stages 1 and 2 of the proposed model. Contrary to the study hypotheses, results indicated that both measures used have similar psychometric properties. Pre‐ to post‐change analyses suggest that the custodial treatment programme may be having some effect on grievance thinking. However, generally offenders' scores on both measures were low pre‐ and post‐treatment and as a result, according to individual change analyses, the majority did not demonstrate reliable or clinically significant change. Those who were classed as high scorers on either measure did, however, demonstrate such change. Conclusions. Further exploration of a three‐stage model of grievance is warranted. It appears that current measures of grievance in sexual offenders are not adequate to capture this concept fully.
