食品安全事件是近年来全球公共安全问题中的热点,由于食品安全的重要性、食品安全事件的公众效应以及基于传媒的属性,媒体常将其作为关注的热点。媒体在食品安全事件中发挥着监测预警、沟通信息、舆论引导等功能,同时也存在关注视角的选择性和职业自律的松懈等不足。作为一种社会公共资源和社会监督力量,基于传媒良知和职业操守,媒体在食品安全事件中必须形成一套良性的应对机制,包括建立信息有效传播机制、建立食品安全事件相关方的沟通协调机制、建立媒体自律机制等。  相似文献

未焊透是压力管道焊接接头常见缺陷之一,严重时会导致管道的承载能力明显降低,进而引发严重的安全事故。 目前我国的《在用工业管道定期检验规程》中对未焊透管道的定级是很保守的,为了减少对未焊透缺陷的返修,文章采 用非线性有限元分析的方法,通过简化未焊透管道的影响因素,并研究在不同载荷工况下管道失效模式与缺陷尺寸的关 系,获得了未焊透管道的极限载荷曲线簇;再运用塑性力学分析方法对有限元分析结果进行筛选,得到了焊接缺陷的安 全尺寸;最终通过试验验证极限载荷数值分析结果的合理性。研究结果表明含有超标焊接缺陷(如未焊透)的管道不通 过复杂应力计算和安全评定即可在保证安全前提下最大限度地使用。  相似文献

随着大众旅游时代的到来,出游人数激增,极易形成高度聚集的游客群,而高聚集的游客群难控难疏,易导致安全事故发生。加强和完善游客高聚集场所的安全管理已成为旅游管理部门一项紧迫而重要的任务。本文主要以国内外政策法规中关于人员密集场所、公共聚集场所的表述为出发点,结合已有研究成果,借鉴人员密集场所的定义,界定“游客高聚集场所”的概念,并就游客高聚集场所的特征进行了讨论;在此基础上,分析了游客高聚集场所面临的风险类型及其相关诱发因素;最后,根据现有人员密集场所的研究进展提出了游客高聚集场所的相关研究议题。  相似文献

在既定资源约束下实现粮食产出最大化是粮食生产安全的核心。而今旨在提升粮食竞争力的农业规模经营虽得到政府力推,却并非保障国家粮食安全的充分条件。在梳理规模经营与粮食安全保障相关争论的基础上,结合调研资料,依次回应了规模经营后农地是否大概率用于种粮、规模经营是否可持续以及规模经营能否保障粮食产量三个焦点问题。研究发现,与小农经营相比,规模经营与种植结构“非粮化”虽无必然联系,却存在规模经济不显著及单产提升乏力等问题。对此,一方面应强化小农扶持力度,巩固维系小农群体的粮食保障功能;另一方面应调整规模经营主体的政策干预结构,除非在规模经济与土地产出率不一致的情形下,应最大化避免对规模经营主体的直接干预,降低政策的扭曲效应,推动规模经济实现。  相似文献

政府在事故预防和处置中居于主导地位.心理学的"华生模式"和"皮亚杰模式"实现"社会学转向",可用以分析政府的责任问题.而安全事故的"强刺激"和"弱刺激"对政府改进效应是不同的.中国当前社会转型中逐步出现了城乡、单位、地方之间而主要表现为阶层之间的利益分割局面.因而政府的责任一方面不仅仅在于对某一事故的"强刺激"进行反应性改进,更应该在于包括"弱刺激"在内逐步把内化以人为本的责任伦理和信念伦理结合起来,对事故进行事前预知和防范,同时另一方面需要抑制精英阶层对整个社会利益的割据,保障社会底层的安全权益,引导底层进行安全维权,乃至抗争上层"官商秩序(结构)"的利益勾结,打破"资(方)强劳(方)弱"、"上(层)强下(层)弱"结构,从消极的"华生模式"转向积极反应的"皮亚杰模式",不断提升政府效率,保障个体生命安全和社会安全.  相似文献

One recent finding about the prostitution market is the differences in the extent and nature of violence experienced between women who work on the street and those who work from indoor sex work venues. This paper brings together extensive qualitative fieldwork from two cities in the UK to unpack the intricacies in relation to violence and safety for indoor workers. Firstly, we document the types of violence women experience in indoor venues noting how the vulnerabilities surrounding work-based hazards are dependent on the environment in which sex is sold. Secondly, we highlight the protection strategies that indoor workers and management develop to maintain safety and order in the establishment. Thirdly, we use these empirical findings to suggest that violence should be a high priority on the policy agenda. Here we contend that the organizational and cultural conditions that seem to offer some protection from violence in indoor settings could be useful for informing the management of street sex work. Finally, drawing on the crime prevention literature, we argue that it is possible to go a considerable way to designing out vulnerability in sex work, but not only through physical and organizational change but building in respect for sex workers rights by developing policies that promote the employment/human rights and citizenship for sex workers. This argument is made in light of the Coordinated Prostitution Strategy.  相似文献

By building on a genetic‐inspired attribute‐based conceptual framework for safety risk analysis, we propose a novel approach to define, model, and simulate univariate and bivariate construction safety risk at the situational level. Our fully data‐driven techniques provide construction practitioners and academicians with an easy and automated way of getting valuable empirical insights from attribute‐based data extracted from unstructured textual injury reports. By applying our methodology on a data set of 814 injury reports, we first show the frequency‐magnitude distribution of construction safety risk to be very similar to that of many natural phenomena such as precipitation or earthquakes. Motivated by this observation, and drawing on state‐of‐the‐art techniques in hydroclimatology and insurance, we then introduce univariate and bivariate nonparametric stochastic safety risk generators based on kernel density estimators and copulas. These generators enable the user to produce large numbers of synthetic safety risk values faithful to the original data, allowing safety‐related decision making under uncertainty to be grounded on extensive empirical evidence. One of the implications of our study is that like natural phenomena, construction safety may benefit from being studied quantitatively by leveraging empirical data rather than strictly being approached through a managerial perspective using subjective data, which is the current industry standard. Finally, a side but interesting finding is that in our data set, attributes related to high energy levels (e.g., machinery, hazardous substance) and to human error (e.g., improper security of tools) emerge as strong risk shapers.  相似文献

ABSTRACT

A recent prevalence of high visibility catastrophic events has garnered increased attention to process safety issues. While the use of Behavior-Based Safety interventions demonstrate a reduction in workplace injuries by targeting employee behavior, we believe that process safety requires a greater focus on the behavior of leaders (e.g., creating and executing strategy). One effective method to begin targeting leader behavior for the improvement of process safety is to teach leaders about the principles of behavior, including ways by which the science may be applied within their own organizational models.  相似文献

In 2012, the Australian Government announced the establishment of a Royal Commission into Institutional Responses to Child Sexual Abuse. The aim of the Royal Commission is to understand how and why sexual abuse occurred within Australian institutions and to provide guidance as to how future abuse might be prevented. The Royal Commission commissioned a mixed methods study to explore what children need to be safe and to feel safe, to explore how they determine their level of safety, and their observations about how institutions act to prevent and respond to safety issues. This article reports on the findings from the first phase of the study that involved focus groups carried out with children aged 4–17 years from different types of institutions. The discussion focused particularly on how children conceptualise safety and how they make judgments about their levels of safety. Children and young people's conceptualisation of safety had multiple dimensions, which include the idea that being safe and feeling safe are two distinct, interrelated but sometimes non‐concurrent experiences; that safety is identified and experienced as a set of feelings; trusting relationships are the foundation of safety; familiarity helps children feel safe; and safe environments are those that are ordered and orderly.  相似文献
