Use of tail areas for testing goodness-of-fit

Characterizing a set of data as a random sample from a specified distribution is often a precursor to statistical inference or hypothesis testing involving the extremes of the distribution -precisely the regions of greatest uncertainty. It seems reasonable then to exploit as best we can our limited knowledge of this region. Toward this end we investigate here the areas in the tails of the distribution as determined by the extreme order statistics as a criterion for testing goodness-of-fit.     

Conformists & mavericks: introducing IT-enabled plurilingual pedagogy informed by the CEFR in high school French immersion

This exploratory case study investigates pathways taken by a Canadian French immersion high school teacher invested in pedagogical change. To fairly evaluate the successfulness of her attempt to effect change, Cummins’ ‘framework of coercive and collaborative relations of power manifested in macro- and micro-interactions’ was employed. Its use shed light on the structural adaptations needed for the innovation she was attempting to introduce to succeed. The teacher wanted to introduce plurilingual pedagogy informed by the Common European Framework of Reference for Languages (CEFR) into a French-medium content-based course by drawing on student ease with using technology such as i-Movie. The findings gained through an analysis of classroom-based observation, interviews, documents and artefacts suggest the structural challenges she faced led her to make decisions at odds with her beliefs and goal of implementing innovative pedagogy (she modified a key aspect of a social justice task). They further suggest a mismatch between what she anticipated student reactions to the innovation would be as compared to their actual reactions. Students welcomed the chance to draw on their out-of-school digital knowledge to reflect their (linguistic) identity through their work, suggesting IT-enabled plurilingual pedagogy informed by the CEFR merits further exploration.     

Factors Associated with Gamblers: A Population-based Cross-sectional Study of South Australian Adults

Objective To determine, using a random telephone survey, the prevalence of various gambling activities among South Australian adults, the prevalence of adult problem gamblers using the South Oaks Gambling Screen (SOGS) instrument, and to examine the problem gamblers by demographic and health-related risk factors.Method A random representative sample of South Australian adults selected from the Electronic White Pages. Overall, 6045 interviews were conducted (73.1% response rate) using Computer Assisted Telephone Interviewing (CATI) technology.Results Overall, 75.6% (95% CI: 74.5–76.7) of respondents had participated in at least one gambling activity during the last 12 months and 2.0% (95% CI: 1.7–2.4) were identified to be problem gamblers. A wide range of factors was associated with problem gambling at a univariate level, when compared to frequent gamblers. The logistic regression analysis highlighted that problem gamblers were more likely to speak a language other than English, be employed part time and a smoker when compared to frequent gamblers. Problem gamblers were also more likely to have a mental health condition (according to the Kessler 10), have had suicidal thoughts and know of services for gambling problems.Conclusion There is a wide range of characteristics associated with problem gambling in South Australia. All of these factors need addressing during policy development to assist problem gamblers.     

Disaster and response:science, systems and realities

The Indian Ocean Tsunami of December 2004 was one of the most significant natural disasters in modern history. The response that it drew was unprecedented at both local and international levels. While a range of specific impacts and losses may be predicted within the affected populations, there is substantial evidence that adverse impacts upon mental health may represent one of the most significant outcomes of such events. People from poorer countries are disproportionately exposed to such emergencies and may experience greater psychosocial burden in the aftermath, as well as a range of adaptations. This raises important questions regarding the current capacity of response agencies to mitigate negative impacts but also concerning the cultural context in which such mental health effects are defined. It also calls into question whether "indicated" interventions are both realistic and ecologically valid in non-Western settings. The science of Disaster Mental Health is a relatively new field, currently engaged in a number of such debates. However, there is some emerging consensus about what constitutes good public mental health practice throughout the phases of emergency response and across diverse cultural settings. Existing data and practice guidelines provide frameworks that may be adapted to allow health and recovery workers to identify and reduce mental health morbidity, support healing and harness the agency of those affected for the recovery process.     

Information and Communication Technologies: Reshaping Voluntary Organizations?

Electronic networking holds the promise of innovation with involuntary organizations as they seek to respond to deep shifts in the social, economic, and political spheres in which they operate. Evidence from our study of U.K. voluntary organizations demonstrates relatively low uptake of the core networking technologies and applications essential to support the reconfiguration of key relationships in and around the organizations. Friends of the Earth and the Samaritans are exceptions to this trend. Case studies of these organizations suggest they are using information and communication technologies to reshape internal relationships and reconfigure relationships externally. The extent to which the organizations are reconfiguring around intelligent campaigning and intelligent client service is tempered by their long‐standing values.
