Structured expert elicitation about Listeria monocytogenes cross-contamination in the environment of retail deli operations in the United States

Listeria monocytogenes is among the foodborne pathogens with the highest death toll in the United States. Ready‐to‐eat foods contaminated at retail are an important source of infection. Environmental sites in retail deli operations can be contaminated. However, commonly contaminated sites are unlikely to come into direct contact with food and the public health relevance of environmental contamination has remained unclear. To identify environmental sites that may pose a considerable cross‐contamination risk, to elucidate potential transmission pathways, and to identify knowledge gaps, we performed a structured expert elicitation of 41 experts from state regulatory agencies and the food retail industry with practical experience in retail deli operations. Following the “Delphi” method, the elicitation was performed in three consecutive steps: questionnaire, review and discussion of results, second questionnaire. Hands and gloves were identified as important potential contamination sources. However, bacterial transfers to and from hands or gloves represented a major data gap. Experts agreed about transfer probabilities from cutting boards, scales, deli cases, and deli preparation sinks to product, and about transfer probabilities from floor drains, walk‐in cooler floors, and knife racks to food contact surfaces. Comparison of experts' opinions to observational data revealed a tendency among experts with certain demographic characteristics and professional opinions to overestimate prevalence. Experts’ votes clearly clustered into separate groups not defined by place of employment, even though industry experts may have been somewhat overrepresented in one cluster. Overall, our study demonstrates the value and caveats of expert elicitation to identify data gaps and prioritize research efforts.     

Being safe from what and safe for whom? A critical discussion of the conceptual metaphor of ‘safe space’

ABSTRACT

Safe space, used in educational settings as a metaphor, stresses the importance of the classroom being a learning environment characterised by respect and safety. Based on examples from Swedish and Norwegian classroom research, this article problematises and discusses the complexity in the discourse on safe space by asking the critical questions: Being safe from what? – and safe for whom? Related to the concept of safe space are questions about what possibly can make the classroom an unsafe place. In addition to various types of intimidation, harassment and attacks, discussions about certain issues and topics can, for various reasons, be perceived as threatening. The school is part of society, and in an increasingly polarised climate, controversial issues in contemporary society will often be perceived as controversial in classroom practice. In this sense, instead of giving students false promises of being safe in the Religious Education (RE) classroom, the concept ‘classroom of disagreement’ may be a useful metaphor, since it makes it explicitly clear that disagreements exist and are part of life.     

Matching deprivation mapping to urban governance in three Indian mega-cities

Recent discussions of poverty recognize its multi-dimensional character, focusing on multiple sources of deprivation that poor households experience. However, for urban planners and politicians to implement intervention programs effectively in mega-cities, knowledge on sources and spatial patterns of multiple deprivations is needed. Disaggregated analysis potentially allows them to target programs to specific locations, set priorities in line with local needs, and be efficient in the use of funding. This article maps multiple deprivations of households in three Indian mega-cities, at the electoral ward level. It uses the livelihoods approach to address the following questions: 1) Is there a spatial concentration of deprivations within cities and do poverty levels differ between them? 2) Do cities differ in the types of deprivations? and 3) do these cluster within the city? The paper compares Delhi, Mumbai and Chennai, using a multi-criteria model within a geographical information system developed for identifying hotspots of multiple deprivation. It further links the results of deprivation mapping to questions of urban governance by comparing deprivation results with data on slums currently used to target anti-poverty programs. Finally, the opportunities of using spatial data for improving priorities and efficient use of funds in poverty programs are analyzed.     

Nonprofit governance during organizational transition in voluntary associations

This explorative field study examines the governance challenges that voluntary associations face in the transition from an internal focus on members to the provision of services to mainly nonmembers. This transition is an important stage in the life cycle of many associations. A qualitative research design was used to study five Swiss patient organizations. This article describes the transition process in terms of five main management challenges: different target groups, self‐help group versus competence center, cooperation, fundraising, and transparency. It then examines the implications for four governance aspects that confront managers and board members: recruitment and selection of board members, tasks of the board, relationship between the board and managing director, and the role of the general assembly of members.     

Implementing and Rethinking the European Union's Asylum Legislation: The Asylum Procedures Directive

The Asylum Procedures Directive, which was put in place in the context of the Common European Asylum System, is expected to both harmonise the asylum procedures in the European Union and to safeguard applicants’ rights. This article explores various steps in the implementation of the directive, starting with transnational negotiations which aim to influence domestic asylum policies. Focusing on asylum systems in Germany and Sweden, the article shows that the way decision makers implement the directive is shaped by diverging domestic asylum policies. The risk of failing common standards, however, is not only a matter of implementation, but inherent in the directive's design. Furthermore, harmonisation does not necessarily improve compliance with the principles of international refugee law. Safeguarding protection seekers’ rights requires rethinking both asylum legislation and the role of the actors who intervene in its implementation.     

Adolescents’ Sexual Initiation: The Interaction of Race/Ethnicity and Immigrant Status

This paper provides an in-depth examination of the joint effects of race/ethnicity and immigrant status on adolescents’ intercourse risk. We employ a sample of 4,535 females and 3,759 males from the National Education Longitudinal Study (NELS 88/94) who were followed for 6 years beginning in the eighth grade. We use discrete-time logistic regression models to estimate the associations of race/ethnicity and immigrant generational status with first intercourse hazard, and to evaluate the statistical interactions between race/ethnicity and immigrant status. Overall, Asian and Hispanic girls had lower and non-Hispanic Black girls had higher estimated risks relative to non-Hispanic White girls. Hispanic boys and White non-Hispanic boys had similar intercourse risks, but Black boys had higher and Asian boys lower relative risks. However, these patterns are contingent on immigrant status. Among girls, the protective effects of Asian or Hispanic identity are found only among second generation youth. Risk profiles for boys are more complex: being a third-plus generation Hispanic is associated with a higher risk while an Asian identity is associated with a lower risk only among first- and second-generation youth. These findings confirm the importance of accounting for the overlap between race/ethnicity and immigrant status in models of adolescent behavior. As the demographic diversity of the US population grows, researchers must include both race/ethnicity and immigrant status in their models of adolescent behavior.     

“Basically it's the Usual Whole Teen Girl Thing”: Stage‐of‐Life Categories on a Children and Young People's Helpline

This article explores the practices of membership categorization in the interactions of clients and counselors on a national Australian helpline (Kids Helpline [KHL]) for children and young persons. Our focus is on membership categories drawn from three membership category devices (MCDs): stage‐of‐life (SOL), age, and family. Analysis draws on data across different contact modalities—email and web‐counseling sessions—to examine how category‐generated features are relevantly occasioned, attended to, and managed by the parties in the course of interaction. This shows clients' use of MCDs in presenting their trouble and building a relevant case for their grievance. By examining counselors' subsequent receipts of the clients' complaints, we are able to trace some of the cultural knowledge that the clients' categorizations make relevant to the counselors. Moreover, the analysis demonstrates how the inherent flexibility of MCDs allows counselors to exploit these same categorial resources and to re‐specify the clients' trouble in a more positive fashion to accomplish counseling work. In explicating how taken‐for‐granted notions of the lifespan as well as of family relations are mobilized by participants in KHL's sessions, the findings contribute to previous studies of social interaction in counseling, and to research on social identity and categorization more broadly.     

The economic evaluation of a Participatory Ergonomics programme to prevent low back and neck pain

This study was an economic evaluation conducted alongside a cluster randomised controlled trial with a follow-up of 12 months. The aim was to evaluate the cost-effectiveness and cost-benefit of the Stay@Work Participatory Ergonomics programme (PE) compared to a control group (no PE). In total, 37 departments (n=3047 workers) were randomised into either the intervention (PE) or control group (no PE). During a meeting, working groups followed the steps of PE, and composed and prioritized ergonomic measures aimed to prevent low back pain (LBP) and neck pain (NP). Working groups had to implement the ergonomic measures within three months in their department. Cost data included those directly related to LBP and NP. Cost-effectiveness analyses (CEA) and cost-benefit analyses (CBA) were performed. After 12 months, health care costs and costs of productivity losses were higher in the intervention group than in the control group (the mean total cost difference was $/euro$127; 95% CI $/euro$-164 - $/euro$418). From a societal perspective, the CEA showed that PE was not cost-effective compared to control for LBP and NP prevalence, work performance, and sick leave. The CBA from a company perspective showed a monetary loss of $/euro$78 per worker. The PE programme was neither cost-effective nor cost-beneficial on any of the effect measures.
