An Agent‐Based Model for Pathogen Persistence and Cross‐Contamination Dynamics in a Food Facility

We used an agent‐based modeling (ABM) framework and developed a mathematical model to explain the complex dynamics of microbial persistence and spread within a food facility and to aid risk managers in identifying effective mitigation options. The model explicitly considered personal hygiene practices by food handlers as well as their activities and simulated a spatially explicit dynamic system representing complex interaction patterns among food handlers, facility environment, and foods. To demonstrate the utility of the model in a decision‐making context, we created a hypothetical case study and used it to compare different risk mitigation strategies for reducing contamination and spread of Listeria monocytogenes in a food facility. Model results indicated that areas with no direct contact with foods (e.g., loading dock and restroom) can serve as contamination niches and recontaminate areas that have direct contact with food products. Furthermore, food handlers’ behaviors, including, for example, hygiene and sanitation practices, can impact the persistence of microbial contamination in the facility environment and the spread of contamination to prepared foods. Using this case study, we also demonstrated benefits of an ABM framework for addressing food safety in a complex system in which emergent system‐level responses are predicted using a bottom‐up approach that observes individual agents (e.g., food handlers) and their behaviors. Our model can be applied to a wide variety of pathogens, food commodities, and activity patterns to evaluate efficacy of food‐safety management practices and quantify contamination reductions associated with proposed mitigation strategies in food facilities.     

Facilitation and Dialogue as Methods of Reflective Practice in Professional Education

Students may fear sharing their learning in public because classrooms are not traditional places where we teach skills needed for mutual understanding, such as facilitation and dialogue. This is a pedagogical challenge for planning, policy, and design fields because contemporary teaching requires collaboration among participants. We propose that learning to work collaboratively in the classroom has broader relevance for practice because it mirrors the learning that happens in organizations. To address this opportunity, we trained students in facilitation and dialogue. In this article, we discuss the design, implementation, and outcomes of this intervention.     

Measuring Economic and Social Impacts of Membership in a Community Development Financial Institution

This study uses qualitative and quantitative measures to answer the question: “does a community development financial institution (CDFI) provide a measurable level of social benefit to its members?” Results indicate that a CDFI does change lives in many important ways, from providing members with the ability to get their financial houses in order, to helping members take control of their financial futures, and finally through building a sense of empowerment that reaches beyond the finances of an individual or family. In general, impacts were greater for lower income and less educated households, households with children, households that used more services, and for households that indicated wealth and asset building services were most important.     

Career Development and Guidance Programs Across Cultures: The Gap Between Policies and Practices

The authors summarize the presentations and discussions contributed to the symposium International Perspectives on Career Development by members of Group 5, who considered the topic of the structure and organization of career development programs in different nations. A capsule picture of the national setting, primary goals, components, objectives, and implementation strategies is presented. Papers fell largely into 4 categories: national programs with several components; large, but more specific programs, serving a national population; smaller programs serving diverse populations; and focused programs. One theme emerged strongly from virtually every presentation: There is a gap, often profound, between policy or vision and reality. Although every nation about which participants heard had laudable policies and had made genuine attempts to assist its people with life career development, many individuals do not have access to quality, or even any, services.     

Trauma, coping resources, and family functioning in emergency services personnel: A comparative study

In this study a sample of male, shift-working, operational ambulance officers were compared with a group of male shift-workers from a range of occupations in which exposure to traumatic events was not inherent in the role ( N = 71). Three dimensions of family functioning were examined: intimacy, conflict, and parenting styles, with respect to occupational type (i.e. work-related exposure to trauma) and accounting for personal resources (coping). Personal resources were found to have a significant impact on the dimensions of family functioning. Furthermore, differences emerged in the pattern of coping between the two groups. Ambulance officers demonstrated a more varied repertoire of personal resources than the control group. Social support was found to be the sole predictor of intimacy and conflict levels in the control sample. However, in the ambulance group social support was predictive of intimacy levels, rational-cognitive strategies were predictive of conflict levels, and self-care, social support, and rational-cognitive strategies were all significantly correlated with the three dimensions of family functioning.     

Child sexual abuse in Leeds before and after Cleveland

We report a retrospective cohort study in which clinical and outcome features of 237 cases of child sexual abuse diagnosed by Leeds paediatricians after Cleveland in 1989 were compared with previously published characteristics of 337 children diagnosed by the same paediatricians before Cleveland in 1985 and 1986. Clinical and diagnostic features also were analysed in two subgroups of the 1989 cohort, those for whom there was no case conference and those in whom further abuse was detected at follow-up examination. The number of cases diagnosed annually remained high, and source of referrals and age and sex distribution were similar. Most suspected perpetrators were from within the home in both cohorts. Some clinical features of the 1989 cohort suggested more physically severe abuse. In 1989 fewer children were registered as sexually abused, or were taken into care, and fewer suspected perpetrators were convicted. From the 1989 cohort those children for whom there was no case conference tended to be older, to disclose and were abused less severely by someone outside their home as compared to those for whom a case conference was held. The children in whom further abuse was detected tended to be younger, to not disclose. to be more severely abused by a perpetrator within the home and to be taken into care as compared to those in whom further abuse was not detected. One or more case conferences were held for nearly all of the children in whom further abuse was detected. For most of the 1989 children no evidence was found indicating receipt of mental health services from other than the key social worker. Implications of these findings are discussed in terms of professional and public knowledge and attitudes regarding children's and parental rights and family preservation.
