Violence against teachers: prevalence and consequences

Data collected from 731 teachers were used to examine the consequences of violence directed toward teachers while in the workplace. Analyses showed that the majority of respondents (n = 585, 80.0%) had experienced school-related violence—broadly defined—at one point in their careers. Serious violence (actual, attempted, or threatened physical violence) was less common, but still common enough to be of concern (n = 202, 27.6%). Violence predicted physical and emotional effects, as well as teaching-related functioning. In addition, a model with fear as a potential mediator revealed that both fear and violence were independently predictive of these negative outcomes. Finally, analyses showed that, in general, women reported higher levels of physical symptoms compared to men. We discuss the implications of violence against teachers in terms of personal consequences and the implications for mental health professionals working in an educational setting.     

A survey of extraction techniques for drugs of abuse in urine

Sixty nine participants in the United Kingdom national external quality assessment scheme for drugs of abuse in urine reported details of their sample extraction technique by questionnaire. Laboratories were categorised by differences in technique and their analytical test results compared for samples containing D-amfetamine 0.4 (4) and 0.8 (3) mg/l, morphine 0.4 (4) and 0.8 (4)mg/l, and benzoylecgonine 0.15/0.2 (2) and 0.45/0.5 (4) mg/l. Values in parentheses are numbers of samples. For amfetamine, there was no significant difference in the frequency of true positive results between liquid-liquid or solid phase extraction and the Toxi-Lab A system at 0.8 mg/l. Toxi-Lab A gave significantly fewer positives when operating below its specified threshold at 0.4 mg/l. Paradoxically, laboratories using >5 ml urine volume performed less well. Acidification of the extract before volume reduction gave significantly more true positives. For extraction of morphine, solid phase systems significantly outperformed both liquid-liquid and the Toxi-Lab A system at both 0.8 and 0.4 mg/l. No significant differences between extraction techniques were demonstrated for analysis of benzoylecgonine.     

Critique of interpretation of high levels of heteroplasmy in the human mitochondrial DNA hypervariable region I from hair

The phenomenon known as heteroplasmy can be operationally observed in some human mitochondrial DNA (mtDNA) samples. Typically, heteroplasmy manifests itself in an individual presenting two mtDNA species that differ at a single base. Heteroplasmy at two, and even possibly three sites, also may occur, but at very low rates. A recent report (Grzybowski, 2000, see ref. [13]) suggests that much higher levels of mtDNA (point substitution) heteroplasmy can occur in hair. This observation is contrary to the experience of the forensic mtDNA community. There are several explanations for the unusual findings of high levels of heteroplasmy. First, the template quantities of DNA are approximately three orders of magnitude higher than required for mtDNA sequencing, and an excessive number of amplification cycles were used. Thus, the protocol used did not follow routine practices by the forensic community. Second, there are misidentifications and tabular errors that call into question the reliability of the findings. Third, by comparing the natural human mtDNA variation with a reference sample population with that observed in the heteroplasmy in hair study, the data are inconsistent with population genetic expectations. The observation of high levels of heteroplasmy may be due to contamination of the samples and/or possibly the amplification of nuclear pseudogenes. The results observed in the heteroplasmy in hair study do not apply to other methods of mtDNA analysis and cannot be used to question the reliability of the current forensic mtDNA practices.     

Recommendations for consistent treatment of length variants in the human mitochondrial DNA control region

Human mitochondrial DNA (mtDNA) analysis is a valuable forensic tool, useful in cases where the amount of extracted DNA is low or highly degraded. Population databases are used to determine the relative rarity of a particular profile obtained in a forensic case. Rather than full DNA sequence information, sequence profiles are compared to a reference sequence, and the differences from the reference are recorded in forensic databases. A standard method is proposed for characterizing length variants, and examples are described using actual human control region mtDNA profiles. Consistency in alignment and nomenclature avoids inadvertently describing two sequences as different when in fact they are the same.     

Applying the Responsibility to Protect to the ‘Arab Spring’

The doctrine of the responsibility to protect, since its inception in the ICISS report of 2001, has been the subject of considerable discussion. Arguably its most publicised component is the principle that the international community has the responsibility to protect civilian populations against severe suffering where the relevant national authorities are unable or unwilling to do so. Consequently, the main focus of discourse upon the responsibility to protect has centred on its impact upon the approach of the international community to intervention in respect of situations posing considerable humanitarian crises. The events of the Arab Spring, in which full blown conflict in some states gave rise to serious human suffering, provided a real opportunity for the international community to evaluate the role of the responsibility to protect in decision-making over responding to such instances, and potentially to develop it into a practical and meaningfully implementable concept. However, due to political flaws inherent in the doctrine, and its arguably overstated significance, the doctrine at best played a minimal role in guiding the international response to developments in the Arab World. Nonetheless, responses to the Arab Spring do allow certain conclusions to be drawn in respect of the future relevance of the doctrine.     

Hurricane Sandy: Environmental Impact and Agency Efforts

In the aftermath of Hurricane Sandy, federal, state, and local agencies have begun to rebuild the City of New York. This article explores the various environmental impacts caused by Hurricane Sandy and government response. But beyond immediate hazard mitigation, government agencies have begun to consider the incorporation of hard and soft infrastructure to mitigate storm surge generated by future storms. This article suggests that while soft infrastructure would produce the smallest environmental impact, compared to other proposals, its integration into the city's ecosystem must be done prudently, especially in the borough of Staten Island.     

The Boomerang Effect: A Case Study of the Murray‐Darling Basin Plan

In the period from 1997 to 2009 Australia experienced a severe drought, which significantly affected the Murray‐Darling Basin. The drought has broken but state governments are still in conflict over water allocations. The establishment of the Murray‐Darling Basin Authority (MDBA) in 2007 was intended to address these issues but the management of the Basin remains complicated by constitutional ambiguity. This paper addresses the question of whether it is possible to implement effective policies for the health of the Murray‐Darling Basin without the present danger of a drought. We suggest that the MDBA has encountered what Beck refers to as the ‘boomerang effect’. The MDBA's plans seem to have produced new challenges and the Authority might find the Basin is exposed to risks it has created.     

Political and Civic Engagement and Participation: Towards an Integrative Perspective

Abstract

This article presents an overview of current understandings in the study of political and civic engagement and participation, drawing in particular on innovations which have emerged from the Processes Influencing Democratic Ownership and Participation (PIDOP) project. For the purposes of the article, ‘engagement’ is defined as having an interest in, paying attention to, or having knowledge, beliefs, opinions, attitudes, or feelings about either political or civic matters, whereas ‘participation’ is defined in terms of political and civic participatory behaviours. The different forms that political and civic engagement and participation can take are outlined, and the factors that are related to different patterns of engagement and participation are reviewed. These factors operate at different levels, and include distal macro contextual factors, demographic factors, proximal social factors, and endogenous psychological factors. An integrative model covering all four levels of factors is outlined. Some findings from the secondary analysis of existing data-sets (including the European Social Survey and the International Social Survey Programme) in the PIDOP project are also reported. These findings show that engagement and participation vary as a function of complex interactions between macro, demographic, and psychological factors. It is argued that multi-level integrative theories, such as the one proposed in the current article, are required to understand the drivers of political and civic engagement and participation, and that policies and interventions aimed at enhancing citizens' levels of engagement and participation need to take this multi-level complexity into account.
