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. 相似文献

In this article, an agent‐based framework to quantify the seismic resilience of an electric power supply system (EPSS) and the community it serves is presented. Within the framework, the loss and restoration of the EPSS power generation and delivery capacity and of the power demand from the served community are used to assess the electric power deficit during the damage absorption and recovery processes. Damage to the components of the EPSS and of the community‐built environment is evaluated using the seismic fragility functions. The restoration of the community electric power demand is evaluated using the seismic recovery functions. However, the postearthquake EPSS recovery process is modeled using an agent‐based model with two agents, the EPSS Operator and the Community Administrator. The resilience of the EPSS–community system is quantified using direct, EPSS‐related, societal, and community‐related indicators. Parametric studies are carried out to quantify the influence of different seismic hazard scenarios, agent characteristics, and power dispatch strategies on the EPSS–community seismic resilience. The use of the agent‐based modeling framework enabled a rational formulation of the postearthquake recovery phase and highlighted the interaction between the EPSS and the community in the recovery process not quantified in resilience models developed to date. Furthermore, it shows that the resilience of different community sectors can be enhanced by different power dispatch strategies. The proposed agent‐based EPSS–community system resilience quantification framework can be used to develop better community and infrastructure system risk governance policies. 相似文献

A provocation?…?the minds of my generation of organizational theorists are haunted by the spectre of scientific discourse, shoehorned into dry genres, bullied by audit regimes that try to wring the passion out of thought. Without gaiety, the science that calls us has no exuberance, it cannot dance. What are the possibilities for writing about organizations that allows the heart's instincts to be followed, the vast possibilities of expression to be explored and enjoyed? I explore this through a form of writing known as fictocriticism – a writing engaged in genre-bending as a literary and theoretical engagement with existence and selfhood. Why import this term into organization studies? Might fictocriticism have some value to ‘us’ who locate ourselves here? I am engaging in a form of romance; a courtship of ideas from elsewhere. What might result from this union is not clear, but it offers hope, excitement and promise. 相似文献

人是生活在秩序维度的,人的生命的价值,尤其是劳动力的价值,与处于不同秩序维度有关系。公共慈善也是如此。它有原始秩序的维度,也有扩展秩序的维度,在不同的维度里,有不同的价值。从特朗普家族慈善基金会的命运,可以见出慈善和慈善组织涉及到的不同维度秩序的冲突。更好地发展慈善和慈善组织,需要解决冲突,在不同的秩序维度里,处理好各个方面的关系。 相似文献

Parenting programmes are widely used in the UK, promoted in policy documents as a cost‐effective way for children's services to address behaviour problems and thereby the longer‐term costs associated with conduct disorders, particularly antisocial behaviour and criminality. To explore whether these programmes are a cost‐effective component of family intervention, this paper examines evidence from cost‐effectiveness studies based on randomized controlled trials, modelling studies estimating longer‐term costs and outcomes, and studies estimating costs of UK parenting programmes, including evidence from routine practice. Findings indicate that parenting programmes have the potential to be cost‐saving in the long term; however, gaps in the evidence include: lack of follow‐up of families who drop out of programmes, absence of control groups in longer‐term follow‐ups, and little information about costs and effects of programmes in routine practice. The size of savings resulting from implementation of effective parenting programmes will depend on the extent to which families likely to be most costly to society attend and experience lasting benefit. 相似文献

Many researchers have explored how people share and construct similar mental models in teams. They have claimed that successful team performance depends on a shared mental model of team members about task, team, equipment and situation. Most of the literature has illustrated simplified relationships between a team's mental model and their performance without a valid instrument addressing the confined and relevant constructs of a shared mental model. This paper describes the instrument development steps and the conceptual framework for factors associated with shared mental models. After development and refinement, the instrument was finalized for use to measure team-related knowledge. The final instrument consists of 42 items that are linked to the five emergent factors of shared mental models including general task and team knowledge, general task and communication skills, attitude toward teammates and task, team dynamics and interactions, and team resources and working environment. 相似文献
