Framework for Microbial Food‐Safety Risk Assessments Amenable to Bayesian Modeling

Regulatory agencies often perform microbial risk assessments to evaluate the change in the number of human illnesses as the result of a new policy that reduces the level of contamination in the food supply. These agencies generally have regulatory authority over the production and retail sectors of the farm‐to‐table continuum. Any predicted change in contamination that results from new policy that regulates production practices occurs many steps prior to consumption of the product. This study proposes a framework for conducting microbial food‐safety risk assessments; this framework can be used to quantitatively assess the annual effects of national regulatory policies. Advantages of the framework are that estimates of human illnesses are consistent with national disease surveillance data (which are usually summarized on an annual basis) and some of the modeling steps that occur between production and consumption can be collapsed or eliminated. The framework leads to probabilistic models that include uncertainty and variability in critical input parameters; these models can be solved using a number of different Bayesian methods. The Bayesian synthesis method performs well for this application and generates posterior distributions of parameters that are relevant to assessing the effect of implementing a new policy. An example, based on Campylobacter and chicken, estimates the annual number of illnesses avoided by a hypothetical policy; this output could be used to assess the economic benefits of a new policy. Empirical validation of the policy effect is also examined by estimating the annual change in the numbers of illnesses observed via disease surveillance systems.     

A cross-national comparison of public project benefits management practices – the effectiveness of benefits management frameworks in application

Abstract

Benefits are the principal reason why an organization may seek to enact change through programmes and projects. The discipline of identification, definition, planning, tracking and realization of benefits is recognized to be instrumental in achieving organizational strategy. In this study, we describe the results of a cross-national comparison of public sector benefits management (BM) practices in Australia, Canada, the UK and the USA. It explores ‘BM practices in action’, considering to what extent ‘espoused’ or ‘mandated’ frameworks are actually practised and perceived by their users. Employing qualitative analysis, semi-structured interview data were analysed from 46 participants with experience in sponsoring, managing and/or reviewing government projects. The results expose considerable variation in the adoption and standardization of BM frameworks from inter and intragovernmental perspectives. We evidence a strong focus on benefits identification across the data set, specifically at the outset (the business case stage seeking project approval) and observe deterioration in focus as the project or programme progresses through the authorization (or assurance) approval gates towards close-out and operations. The results further emphasize the prominence of political interest, leadership buy-in, a benefits-driven culture and a transparent benefits reporting mechanism in the implementation of ‘effective’ BM frameworks.     

Body Talk and Boundary Work Among Arab Canadian Immigrant Women

This paper places Latour’s (2004) concept of “body talk” alongside literature on symbolic boundaries to consider how the symbolic judgements and evaluations that comprise body talk frame the impact of structural pressures on the body. Drawing from individual and focus group interviews with 36 first-generation Arab Canadian immigrant women, this study shows that the female body, and practices of feeding and exercising it, are sites where structural inequalities embedded in the immigration process are materially experienced, resisted, and managed. In constructing boundaries between Arab women’s bodies in Canada and the Arab world alongside those of so-called “Canadian” women, we argue that women communicate their immigration and settlement struggles and recoup dignity otherwise compromised in the migration process—ultimately allowing them to frame their struggles as products of their moral integrity as immigrant wives and mothers. Through these findings, this paper demonstrates the role of body talk in framing the impact of structural pressures on the body, while simultaneously highlighting the centrality of boundary work to that framing.

     

Transformative learning for social integration: overcoming the challenge of greetings

Many universities in different parts of the world are seeking to enhance the cultural diversity of their staff and student body and yet repeated studies have shown that good integration can be difficult to achieve. Although several studies have examined the reasons why such integration is difficult, there has been very little research into the actual process of social integration. This paper addresses this gap through a qualitative study of intercultural learning. Students were asked to focus on a behaviour that was personally or professionally important to them but that they were having difficulty adapting to. The paper reports the varying, unfolding experiences of six of these students as they faced the affective, behavioural and cognitive challenges of adjusting to different greeting patterns and the strategies they used for gradually overcoming them. Drawing on the literature and the findings, an intercultural growth model is proposed. The paper ends with a discussion of the implications of the findings for enhancing social integration at university.     

Theory of mind as a mechanism linking mother–toddler relationship quality and child–friend interaction during the preschool years

Children's relationships with parents and peers have been examined as predictors and outcomes, respectively, of theory of mind (ToM). Yet, these two lines of inquiry have remained largely distinct. The current study bridges this gap. Mother–child coordinated interaction and attachment security (continuous rating) were assessed at 2.8 years (N = 128 dyads), ToM was assessed at 3.3, 4.8, and 5.4 years, and child–friend interaction was observed at 4.8 and 5.4 years. Controlling for child expressive language ability at 2.8 years, mother–child coordinated interaction predicted more complex child–friend play and less child–friend conflict via more advanced ToM. No indirect effects from attachment security to friendship quality via ToM emerged. Attachment group status (secure vs. insecure), however, moderated ToM‐friendship associations, such that (a) more advanced ToM predicted more socially complex play with friends, and (b) more conflict with friends predicted more advanced ToM, but only for children classified as secure.     

The impact of the COVID-19 pandemic on the mental health and well-being of children and young people

The COVID-19 pandemic has had an enormous impact across the world. In this discussion paper, we examine the effect that lockdown has had on the mental health and well-being of children and young people. We write from a UK perspective in the light of the international evidence. Many of the discussion points raised resonate globally. We discuss how these issues can be dealt with and set out potential solutions as we emerge from this global crisis.     

Assessment of the psychometric properties of the Graded Care Profile version 2 (GCP2) tool for measuring child neglect

Child neglect is highly prevalent, with extensive effects on children's development and often long‐lasting consequences. It is a complex issue, and the identification and assessment of neglect presents particular difficulties for professionals. The Graded Care Profile (GCP) is a tool that can help practitioners to assess neglect, but the updated version of this tool (GCP2) requires psychometric testing. We sought to test the GCP2 with qualified social work practitioners in the United Kingdom. Interrater reliability was assessed by comparing GCP2 scores between 3 pairs of practitioners following assessments of 30 children. Concurrent validity was assessed by comparing GCP2 scores to scores obtained using 2 other validated measures with 15 children. Professionals were surveyed concerning face validity. There was a substantial level of interrater agreement for 2 domains and a moderate level of agreement for the other 2 domains. There were strong correlations between the GCP2 and the other tools across all domains, and face validity results were positive. In conclusion, although this was a small sample, our findings provide preliminary evidence that the GCP2 has adequate psychometric properties pending further rigorous psychometric testing. It is thus likely to be a useful tool in aiding professionals in the assessment of child neglect.     

Exposure to Parent and Peer Alcohol Use and the Risk of Drinking Onset and Escalation Among Adolescents

Although the rate of alcohol use among adolescents has declined, it remains their drug of choice. Parent and peer alcohol use are powerful risk factors for youth alcohol use. However, questions remain about how these factors influence underage drinking. The present study investigates the relationship between exposure to parent or peer alcohol use and two stages of adolescent drinking—onset and escalation—overall and at five age points during adolescence. Participants were 9348 adolescents in Waves I (WI) and II (WII) of the National Longitudinal Study of Adolescent Health, whose parents completed interviews at WI, and who identified themselves as either non-drinkers or experimental drinkers at WI. Reports of WII alcohol use were used to measure onset among WI non-drinkers and escalation among WI experimenters. Risk ratios were calculated to assess the overall impact of exposure to parent or peer alcohol use on onset and escalation, and at five age points (i.e., ≤?13, 14, 15, 16, and ≥?17). Findings show that exposure to either parent or friend alcohol use increased the risk of onset and escalation. Age-based analyses reveal a more nuanced relationship, showing variability in the nature and strength of influence by stage of drinking and by age. This study highlights the relevance of both parent and peer modeling on youth drinking throughout adolescence. Implications in advancing prevention and treatment include parental education about the impact of their own behaviors and the importance of monitoring teens’ friendships.
