People often struggle when making Bayesian probabilistic estimates on the basis of competing sources of statistical evidence. Recently, Krynski and Tenenbaum (Journal of Experimental Psychology: General, 136, 430–450, 2007) proposed that a causal Bayesian framework accounts for peoples’ errors in Bayesian reasoning and showed that, by clarifying the causal relations among the pieces of evidence, judgments on a classic statistical reasoning problem could be significantly improved. We aimed to understand whose statistical reasoning is facilitated by the causal structure intervention. In Experiment 1, although we observed causal facilitation effects overall, the effect was confined to participants high in numeracy. We did not find an overall facilitation effect in Experiment 2 but did replicate the earlier interaction between numerical ability and the presence or absence of causal content. This effect held when we controlled for general cognitive ability and thinking disposition. Our results suggest that clarifying causal structure facilitates Bayesian judgments, but only for participants with sufficient understanding of basic concepts in probability and statistics.

Objective. To create, implement, and evaluate debate as a method of teaching pharmacy undergraduate students about ethical issues.

Design. Debate workshops with 5 hours of contact with student peers and facilitators and 5 hours of self-study were developed for second-year pharmacy students. Student development of various skills and understanding of the topic were assessed by staff members and student peers.

Assessment. One hundred fifty students completed the workshops. The mean score for debating was 25.9 out of 30, with scores ranging from 23.2 to 28.7. Seventy percent of students agreed that the debates were a useful teaching method in the degree program.

Conclusion. A series of workshops using debates effectively delivered course content on ethical issues and resulted in pharmacy students developing skills such as teamwork, peer assessment, communication, and critical evaluation. These findings suggest that pharmacy students respond favorably to a program using debates as a teaching tool.

Using rewards may be an effective method to positively influence adolescent eating behaviour, but evidence regarding this approach is limited. The aim of this study was to explore young adolescent views about a proposed reward intervention associated with food choice in school canteens. Focus groups were held in 10 schools located in lower socioeconomic areas within Northern Ireland and involved 90 pupils aged 11-12 years (54 girls, 36 boys). Our findings indicated a high degree of acceptability for a reward scheme but there was major diversity in the type of rewards valued by pupils, largely defined by geographical area and socio-cultural differences. Pupils from rural areas tended to emphasize group-based and longer-term rewards, whereas pupils from urban-city schools tended to suggest individualistic and immediate rewards. The major factors influencing food choice were food price, value for money, taste and visual appearance. Pupils felt that factors outside of their control, such as being assigned to the second lunch sitting placed considerable constraints on their food choice. This research not only indicated a high degree of acceptability for a rewards-based intervention but also highlighted a number of socio-cultural and environmental factors that should be considered by researchers when developing such an intervention.

Tackling food-related health conditions is becoming one of the most pressing issues in the policy agendas of western liberal democratic governments. In this article, I intend to illustrate what the liberal philosopher John Stuart Mill would have said about legislation on unhealthy food and I focus especially on the arguments advanced by Mill in his classic essay On Liberty ([1859] 2006). Mill is normally considered as the archetype of liberal anti-paternalism and his ideas are often invoked by those who oppose state paternalism, including those who reject legislation that restricts the consumption of unhealthy food. Furthermore, his views have been applied to related policy areas such as alcohol minimum pricing (Saunders 2013) and genetically modified food (Holtug 2001). My analysis proceeds as follows. First, I show that Mill’s account warrants some restrictions on food advertising and justifies various forms of food labelling. Second, I assess whether and to what extent Mill’s ‘harm principle’ justifies social and legal non-paternalistic penalties against unhealthy eaters who are guilty of other-regarding harm. Finally, I show that Mill’s account warrants taxing unhealthy foods, thus restricting the freedom of both responsible and irresponsible eaters and de facto justifying what I call ‘secondary paternalism’.

A framework supporting fast prototyping as well as tuning of distributed applications is presented. The approach is based on the adoption of a formal model that is used to describe the orchestration of distributed applications. The formal model (Orc by Misra and Cook) can be used to support semi-formal reasoning about the applications at hand. The paper describes how the framework can be used to derive and evaluate alternative orchestrations of a well know parallel/distributed computation pattern; and shows how the same formal model can be used to support generation of prototypes of distributed applications skeletons directly from the application description.

Following earlier work demonstrating the utility of Orc as a means of specifying and reasoning about grid applications we propose the enhancement of such specifications with metadata that provide a means to extend an Orc specification with implementation oriented information. We argue that such specifications provide a useful refinement step in allowing reasoning about implementation related issues ahead of actual implementation or even prototyping. As examples, we demonstrate how such extended specifications can be used for investigating security related issues and for evaluating the cost of handling grid resource faults. The approach emphasises a semi-formal style of reasoning that makes maximum use of programmer domain knowledge and experience.

The present study tested the hypothesis that adolescents growing up in Children's Homes differ from adolescents growing up in a family environment in how they think about their past, present and future, in the way they make decisions about future events and rewards, and in their levels of empathy and perspective taking. The participants were 40 adolescents from Children's Homes in Budapest, Hungary, and 40 age- and gender-matched controls. Group differences were found in participants' past and present time perspectives, and girls from Children's Homes showed reduced consistency in their plans for the future. Additionally, gender differences emerged in empathy, perspective taking, and in participants' present and future time perspectives. We discuss the implications of our findings for interventions to improve the future prospects of adolescents in Children's Homes.

Following the UK Medical Research Council’s (MRC) guidelines for the development and evaluation of complex interventions, this study aimed to design, develop and optimise an educational intervention about young men and unintended teenage pregnancy based around an interactive film. The process involved identification of the relevant evidence base, development of a theoretical understanding of the phenomenon of unintended teenage pregnancy in relation to young men, and exploratory mixed methods research. The result was an evidence-based, theory-informed, user-endorsed intervention designed to meet the much neglected pregnancy education needs of teenage men and intended to increase both boys’ and girls’ intentions to avoid an unplanned pregnancy during adolescence. In prioritising the development phase, this paper addresses a gap in the literature on the processes of research-informed intervention design. It illustrates the application of the MRC guidelines in practice while offering a critique and additional guidance to programme developers on the MRC prescribed processes of developing interventions. Key lessons learned were: 1) know and engage the target population and engage gatekeepers in addressing contextual complexities; 2) know the targeted behaviours and model a process of change; and 3) look beyond development to evaluation and implementation.

Science journalism is the source of much of the science an individual will encounter beyond formal education. Science-based media reports, which might have been associated with informal education, are increasingly becoming incorporated into formal school contexts. Unlike science textbooks, the science reported in the news is often tentative and sometimes contested. It can involve difficult socio-scientific issues. Descriptors of ‘science literacy’ generally include reading and responding critically to media reports of science. The challenge of using science-based news effectively encourages teachers to reassess their knowledge and pedagogical practices.
In addition to creating interest in science and making links beyond the classroom, news media can be used to introduce pupils to elements of science enquiry and teachers can promote basic literacy and critical reading skills through systematic and imaginative use of media reports with a science component.
This chapter explores the knowledge, skills and attitudes that underpin the use of science journalism in the classroom. The unique characteristics and constraints of science journalism that influence the way science is presented and perceived are considered, and the importance of media awareness as a foundation for critical reading of science news is argued. Finally the characteristics of teaching programmes to support critical engagement with science-based media reports are outlined and the opportunities for cross-curricular initiatives highlighted.

Gestational diabetes mellitus (GDM) is glucose intolerance that begins or is first identified during pregnancy. GDM is associated with increased perinatal morbidity.1 In the long term women with GDM have a seven-fold risk of developing type 2 diabetes in later life compared to pregnancies with normal blood glucose levels.2 Recent research has centred on investigating the effect of treating GDM on pregnancy outcome, and defining the diagnostic criteria for GDM. This research has led to the recent recommendations from the International Association of Diabetes and Pregnancy Study Groups (IADPSG) for diagnosis of GDM.3 Prevalence of GDM has increased in recent years, alongside an increased prevalence of type 2 diabetes in the background population. Additionally, the adoption of IADPSG criteria has even further increased GDM prevalence almost three-fold in some populations.4

Across four studies, we directly compared children’s essentialist reasoning about the stability of race and language throughout an individual’s lifespan. Monolingual English-speaking children were presented with a series of images of children who were either White or Black; each face was paired with a voice clip in either English or French. Participants were asked which of two adults each target child would grow up to be – one who was a ‘match’ to the target child in race but not language, and the other a ‘match’ in language but not race. Nine- to 10-year-old European American children chose the race-match, rather than the language-match. In contrast, 5–6-year-old European American children in both urban, racially diverse, and rural, racially homogeneous environments chose the language-match, even though this necessarily meant that the target child would transform racial categories. Although surprising in light of adult reasoning, these young children demonstrated an intuition about the relative stability of an individual’s language compared to her racial group membership. Yet, 5–6-year-old African American children, similar to the older European American children, chose the race-match, suggesting that membership in a racial minority group may highlight children’s reasoning about race as a stable category. Theoretical implications for our understanding of children’s categorization of human kinds are discussed.

Objective: The present study aimed to examine the role of health in consumers’ food purchasing decisions through investigating the nature of people’s discourse regarding health while conducting their food shopping.

Design: The study employed the think-aloud technique as part of an accompanied shop. All mentions of health and terms relating to health were identified from the data set. Inductive thematic analysis was conducted to examine how health was talked about in relation to people’s food choice decisions.

Setting: Supermarkets in Dublin, Republic of Ireland and Belfast, Northern Ireland.

Subjects Participants: (n 50) were aged over 18 years and represented the main household shopper.

Results: Responsibility for others and the perceived need to illicit strict control to avoid ‘unhealthy’ food selections played a dominant role in how health was talked about during the accompanied shop. Consequently healthy shopping was viewed as difficult and effort was required to make the healthy choice, with shoppers relating to product-based inferences to support their decisions.

Conclusions: This qualitative exploration has provided evidence of a number of factors influencing the consideration of health during consumers’ food shopping. These results highlight opportunities for stakeholders such as public health bodies and the food industry to explore further ways to help enable consumers make healthy food choices.
