Supporting Critical Multicultural Teacher Educators: Transformative teaching,social justice education,and perceptions of institutional support

ABSTRACT

In most teacher education programmes in Canada and the United States, educators’ opportunities to develop equity-related skills are concentrated into single ‘multicultural’ courses. These courses tend to have a conservative or liberal orientation, focused on appreciating diversity or cultural competence, rather than a critical orientation, focused on preparing teachers to address inequity. In this study, based on a survey of instructors of multicultural and intercultural teacher education courses in Canada and the US (N = 186), we examined the relationship between the criticality of their multicultural teacher education courses and their perceptions of institutional support for the values they teach. We found a negative relationship between the two – the more critical the instructors’ approaches, the less institutional support they perceived.     

Using Bayesian analysis in repeated preclinical in vivo studies for a more effective use of animals

Whilst innovative Bayesian approaches are increasingly used in clinical studies, in the preclinical area Bayesian methods appear to be rarely used in the reporting of pharmacology data. This is particularly surprising in the context of regularly repeated in vivo studies where there is a considerable amount of data from historical control groups, which has potential value. This paper describes our experience with introducing Bayesian analysis for such studies using a Bayesian meta‐analytic predictive approach. This leads naturally either to an informative prior for a control group as part of a full Bayesian analysis of the next study or using a predictive distribution to replace a control group entirely. We use quality control charts to illustrate study‐to‐study variation to the scientists and describe informative priors in terms of their approximate effective numbers of animals. We describe two case studies of animal models: the lipopolysaccharide‐induced cytokine release model used in inflammation and the novel object recognition model used to screen cognitive enhancers, both of which show the advantage of a Bayesian approach over the standard frequentist analysis. We conclude that using Bayesian methods in stable repeated in vivo studies can result in a more effective use of animals, either by reducing the total number of animals used or by increasing the precision of key treatment differences. This will lead to clearer results and supports the “3Rs initiative” to Refine, Reduce and Replace animals in research. Copyright © 2016 John Wiley & Sons, Ltd.     

Physical environments and community reintegration post stroke: qualitative insights from stroke clubs

This study investigated the environment’s role in community reintegration amongst persons with experience of stroke. Focus group discussions with 29 individuals recruited from community stroke clubs in Scotland revealed that stroke influenced a person’s perceptions, experience, use and enjoyment of the environment. Multiple specific (e.g. theatres, cafes) and more general (out-of-the-home) environments appeared capable of supporting community reintegration, providing settings in which individuals were able and willing to interact with others and participate in various functional, social and recreational activities. The article reflects on the study’s implications for policy and practice.     

Targeting the worst-off for free health care: a process evaluation in Burkina Faso

Effective mechanisms to exempt the indigent from user fees at health care facilities are rare in Africa. A State-led intervention (2004-2005) and two action research projects (2007-2010) were implemented in a health district in Burkina Faso to exempt the indigent from user fees. This article presents the results of the process evaluation of these three interventions. Individual and group interviews were organized with the key stakeholders (health staff, community members) to document the strengths and weaknesses of key components of the interventions (relevance and uptake of the intervention, worst-off selection and information, financial arrangements). Data was subjected to content analysis and thematic analysis. The results show that all three intervention processes can be improved. Community-based targeting was better accepted by the stakeholders than was the State-led intervention. The strengths of the community-based approach were in clearly defining the selection criteria, informing the waiver beneficiaries, using a participative process and using endogenous funding. A weakness was that using endogenous funding led to restrictive selection by the community. The community-based approach appears to be the most effective, but it needs to be improved and retested to generate more knowledge before scaling up.     

Moving Beyond Basic Emotions in Aging Research

There is consistent evidence that older adults have difficulties in perceiving emotions. However, emotion perception measures to date have focused on one particular type of assessment: using standard photographs of facial expressions posing six basic emotions. We argue that it is important in future research to explore adult age differences in understanding more complex, social and blended emotions. Using stimuli which are dynamic records of the emotions expressed by people of all ages, and the use of genuine rather than posed emotions, would also improve the ecological validity of future research into age differences in emotion perception. Important questions remain about possible links between difficulties in perceiving emotional signals and the implications that this has for the everyday interpersonal functioning of older adults.     

Human Interindividual Variability in Susceptibility to Airborne Particles

Part of the explanation for the persistent epidemiological findings of associations between mortality and morbidity with relatively modest ambient exposures to airborne particles may be that some people are much more susceptible to particle-induced responses than others. This study assembled a database of quantitative observations of interindividual variability in pharmacokinetic and pharmacodynamic parameters likely to affect particle response. The pharmacodynamic responses studied included data drawn from epidemiologic studies of doses of methacholine, flour dust, and other agents that induce acute changes in lung function. In general, the amount of interindividual variability in several of these pharmacodynamic response parameters was greater than the variability in pharmacokinetic (breathing rate, deposition, and clearance) parameters. Quantitatively the results indicated that human interindividual variability of breathing rates and major pharmacokinetic parameters-total deposition and tracheobronchial clearance-were in the region of Log(GSD) = 0.1 to 0.2 (corresponding to geometric standard deviations of 10(.1)-10(.2) or 1.26-1.58). Deposition to the deep lung (alveolar region) appeared to be somewhat more variable: Log(GSD) of about 0.3 (GSD of about 2). Among pharmacodynamic parameters, changes in FEV1 in response to ozone and metabisulfite (an agent that is said to act primarily on neural receptors in the lung) were in the region of Log(GSD) of 0.2 to 0.4. However, similar responses to methacholine, an agent that acts on smooth muscle, seemed to have still more variability (0.4 to somewhat over 1.0, depending on the type of population studied). Similarly high values were suggested for particulate allergens. Central estimates of this kind of variability, and the close correspondence of the data to lognormal distributions, indicate that 99.9th percentile individuals are likely to respond at doses that are 150 to 450-fold less than would be needed in median individuals. It seems plausible that acute responses with this amount of variability could form part of the mechanistic basis for epidemiological observations of enhanced mortality in relation to ambient exposures to fine particles.
