A Model for Setting Performance Objectives for Salmonella in the Broiler Supply Chain

A stochastic model for setting performance objectives for Salmonella in the broiler supply chain was developed. The goal of this study was to develop a model by which performance objectives for Salmonella prevalence at various points in the production chain can be determined, based on a preset final performance objective at the end of the processing line. The transmission of Salmonella through the broiler production chain was modeled. The prevalence at flock level was calculated from the measured prevalence at sample level. The transmission model is based on data on the occurrence of Salmonella collected in the Dutch broiler production chain during several years. The developed model can be used by policymakers and industry to determine economically and politically acceptable performance objectives for various points of the production chain and to draw conclusions about which interventions are most appropriate.

公共领域问题溯源——启蒙、罗尔斯与哈贝马斯

论述公共领域的存在及其问题界定源于启蒙运动的三大理想;经由罗尔斯将正义问题界定为其基本问题,哈贝马斯则基于＂交往＂和＂交互主体性＂对公共领域及其问题进行了新的思考,对于公共领域及公共政策的思考展现为一个逐步展开的理论思维过程。指出公共领域的存在是公共政策制定的前提和基础,公共领域的概念理清关乎解决公共领域中的问题争论。     

Changes in Risk Perceptions Prospectively Predict Changes in Self‐Reported Speeding

Risk perception theories posit that changes in risk perception prompt subsequent changes in risk behavior. Prospective studies using observations made at three time‐points offer the capacity to test this hypothesis by observing sequential changes in both risk perceptions and behavior. A telephone survey was administered by random‐digit dialing to 255 adult Australian drivers at baseline (T1), 6 weeks (T2), and 14 weeks (T3). During weeks 2–5, a risk‐perception‐based anti‐speeding mass media campaign was conducted. The survey assessed risk perception, operationalized as the proportion of time that driving at 70 km/h (43 mph) was perceived to be dangerous, and self‐reported speeding behavior, defined as the frequency of respondents driving 5 km (3 mph) faster than the legal speed limit in built up areas. Higher T2 risk perception predicted lower T3 self‐reports of speeding after controlling T1 risk perception and T1 and T2 self‐reported speeding. This can be interpreted as changes in risk perceptions between T1 and T2 predicting changes in speeding between T2 and T3. Further analyses showed that increases in risk perception predicted lower subsequent self‐reported speeding changes, but decreases in risk perception were unrelated to those changes. Risk perception changes were unrelated to recall of exposure to the media campaign. These findings support a dynamic view of the relationship between risk perception and self‐reported behavior, and that risk perception theories can be applied to speeding.

转型期乡土法律文化对乡镇煤矿安全法制影响力考察

当前,乡镇煤矿事故频繁发生,成为煤矿安全监察的＂老大难＂。由于乡镇煤矿在地理位置上位于乡村、小镇一带,矿工大多来自本地农民工,因此,解构转型期乡土法律文化,从另一视角研究乡镇煤矿安全法制,对我国乡镇煤矿立法不无裨益。转型期村民法律心理、法律意识有其特殊性,当前关于乡镇煤矿的法律制度不完备,乡村维权机构与设施不合理。针对以上问题,建议对乡镇煤矿立法时,应遵循法律文化生成机理,并对立法技术进行改进,还须增设乡村维权机构。

农村非营利组织发展的价值与前景分析

文章指出，传统农村社会中的非营利组织曾在公共产品的供给过程中起到积极的作用。改革开放以来，农村新出现的非营利组织既是基于农民的维护个人的经济和社会权利的现实需求，也是经济社会发展的必然结果。它在公共服务和公共产品的供给、维护社会公平、培养新型农民方面起到积极的作用。农村非营利组织还需要在政府的支持下实现规范化管理，建立起良好的组织间网络。
