title: Drugs and driving in New Zealand: An approach to THC culpability

authors: Troncoso Vergara, Carolina

subjects: drugs and driving

abstract: For years statistical analysis has been applied to different areas of the natural and applied sciences to determine the degree of confidence that can be placed in research results.

This work is a good example of how statistics can be applied to toxicology to enable conclusions and inferences to be made about important areas of interest such as the drugs and driving situation in New Zealand.

Two thousand uninjured drivers (Study 1) who had provided an evidential blood alcohol sample, were also tested for cannabis, methamphetamine, benzodiazepines and morphine to determine the incidence of drug use by drinking drivers.
 
To determine the proportion of drivers killed in car crashes who had used drugs and/or alcohol, two hundred and twenty nine fatally injured drivers (Study 2) were tested for alcohol, cannabis, methamphetamine, morphine, benzodiazepines and neutral and basic medicinal drugs that might have an effect on driving performance. 

Alcohol, cannabis and their combination were found to be the most prevalent drugs used by drivers. 

The analytical methodologies used were developed and validated by the Institute of Environmental Science and Research Ltd., where this work was carried out. These techniques involved liquid-liquid and liquid-solid extractions, immunoassays and chromatographic techniques for screening and confirmation assays. The statistical analysis of the results was done under the supervision of the Institute's biostatistician.

An approach to cannabis culpability, intended to elucidate the role of this drug in car crashes, was applied to the Study 2 results. The number of samples collected during one year of research was not sufficient to enable statistically robust conclusions to be drawn.

Cannabis use is illegal in New Zealand but drugs (different to alcohol) are not regularly tested at the roadside. This work as part of a cross-departmental project titled  Drinking and drugged driver control: delineating the problem  is expected to support the establishment of strategies designed to reduce the road toll and possibly include the screening of non-alcohol drugs in serious and fatally injured drivers.

title: Subject(s) matter: a grounded theory of technology teachers’ conceptions of the purpose of teaching technology

authors: Doyle, Andrew

abstract: Technology education internationally has for some time struggled to achieve continuity between what is depicted in policy and curricular documents and the reality of day-to-day practices. With its focus often articulated through the nature of activity students are to engage with, technology teachers are recognised as having significant autonomy in the design and implementation of their practices. From this, it is important to understand teachers’ beliefs about technology education, as their conceptions of the subject will inform practice. As such, this study sought to investigate teachers’ conceptions of the purpose of teaching technology through reflection on their enacted practices. A constructivist grounded theory methodology was employed for the design of the study and analysis of data. According to our analysis, despite similarities between the nature of student activity that teachers designed and implemented, teachers represented the purpose of the subject in different ways. Three different conceptions of the purpose of teaching technology were identified; obtaining knowledge and skills for application, ability to act in a technological way, and ability to think in a technological way. Central to the three conceptions were contentions in the representations of what constituted subject matter knowledge in the subject, and the role that different application cases played in teaching technology. Without consideration and explicit articulation of the purposes for teaching technology, this lack of clarity and differences in rationale for teaching technology are likely to continue.

title: Māori women and intimate partner violence: Some sociocultural influences

authors: Hoeata, Chloe

subjects: intimate partner violence

abstract: Intimate partner violence (IPV) has recently been acknowledged as a worldwide phenomenon, with approximately one in four intimate relationships containing some form of violence. This study explores the interaction between relationship dynamics, IPV and whānau and community influences. We completed narrative interviews with two Māori women in December 2010. Our findings confirm the results of earlier studies which have found that childhood experiences of violence, actual or witnessed, have a powerful effect that reverberate within adult lives and into the formation of intimate relationships. Our interviews show that Māori whānau and women are textured by the same patriarchal expectations that privilege men in the Pākehā world. We also found that seeking help from whānau to escape a violent relationship may not be the most welcomed course of action. We conclude with a discussion of future research directions.
