食品抽样工作的风险与防控措施研究

食品抽样工作作为保证食品安全的重要环节,与食品质量和人们的生命健康安全有着直接的联系。受外在因素的影响,目前在食品抽样过程中仍存在着许多风险,严重影响了抽样工作的落实效果。基于此,本文围绕食品抽样检验工作现状,对常见的风险问题进行分析,并提出相应的防控措施,以期能有效降低抽样风险点,保证食品的安全。     

城市地下管网震后安全恢复评价曲线研究

安全恢复评价曲线（$RAC）是应用主分量分析法降维的思想,根据管网恢复评价指标中存在着一定相关性的特点,用较少的指标来代替原来较多的指标,描点形成安全恢复评价曲线。该曲线很好地解决了管网震后恢复评价过程中,多指标评价带来的选取指标过程中的主观性和由此导致的评价结果的偏差等问题,有效地提高评价的精度和效率。文章阐述了SXAC的原理与构造方法,结合聚类分析,给出了SRAC评价应用算例。     

Visitor perceptions of crime-safety and attitudes towards risk: The case of Table Mountain National Park,Cape Town

This paper investigates tourist perceptions of crime-safety and attitudes towards risk whilst visiting Table Mountain National Park (TMNP) in Cape Town in June and July 2008. The study examined survey data of 303 domestic and international tourists during their visit to TMNP. A linear regression analysis revealed that although visitors had concerns about their personal safety they are still likely to return to TMNP and recommend it to other people. In addition, visitor attitudes towards risk did not influence perceptions of crime-safety and its effect on their intentions to revisit or recommend TMNP. The results also show that respondent's individual characteristics such as age, nationality, and purpose of visit influenced their perceptions of crime-safety. Perceptions that TMNP is unsafe tended to increase with respondent's age. Respondents on holiday were more likely to perceive TMNP as safer than those on business or visiting friends and relatives. The study's findings add to the literature by offering more insight on tourist perceptions of crime-safety and attitudes towards risk and their impact on tourist behaviour. Various tourist-crime prevention measures to enhance visitor safety at national parks are also recommended to the tourism industry and law enforcement agencies.     

Investigating menu kilojoule labelling policy adoption from a political science perspective

Implementation of internationally recommended policy options for obesity prevention has generally been slow and inadequate globally, and, as such, it is important to understand barriers and enablers to policy action in the area. This study aimed to apply political science theories to understand influences on the adoption of Menu Kilojoule Labelling Legislation in Victoria, Australia over the period 2009–2017. Data collection included 13 in-depth semi-structured interviews with participants of the policy development and decision-making processes, analysis of 68 policy documents, and field note observations. Data were analysed using established political science theories: the Advocacy Coalition Framework (ACF) and the Multiple Streams Theory (MST). There were numerous and interrelating factors that influenced the Menu Kilojoule Labelling Legislative policy processes. Barriers to policy reform included electoral turnover, a dominance of neoliberal ideology, and policy maker concerns regarding potential food industry backlash. Key enablers to eventual policy change included the accumulation of evidence on policy effectiveness and feasibility of implementation, increased recognition of the importance of tackling the issue, as well as reductions in political risks achieved, in part, through relatively long consultation and negotiation processes. Findings highlight several tactics that can be used to secure similar policy change in future, including generation, dissemination and translation of implementation evidence, effective mobilisation of supporters, and negotiation and consultation processes that can reduce the degree of opposition to proposed policies.     

我国高新技术企业国际化经营中的风险管理研究

近年来,高新技术产业在全球范围内飞速发展,而我国也一直把发展高新技术作为国际经济竞争和综合国力较量的重点,积极鼓励并支持高新技术企业"走出去",从事国际化经营。然而,高新技术企业是典型的风险企业,加之全球经济的诸多不确定因素逐渐显露,对我国高新技术企业国际化经营带来了一定的负面影响。本文从高新技术企业国际化经营影响因素入手,以风险管理过程为主体,构建高新技术企业国际化经营的风险识别机制,并运用模糊综合评价等方法,建立我国高新技术企业国际风险评价模型,最终探讨我国高新技术企业国际化经营中的风险管理系统。

陶二煤矿突出煤层石门反向揭煤技术研究

在突出矿井突出煤层石门揭煤过程中,由于穿越石门和煤门的距离长,工程周期长,揭煤时诱发突出危险的可能性大,而且在放炮揭煤时很难一次揭穿煤层,极易发生延期突出,一直以来是煤矿防突技术难题,给生命和财产带来巨大损失。陶二煤矿利用石门反向揭煤技术安全快速揭开高突煤层,具有抽放时间短、节省岩石钻孔工程量等技术优点,为煤与瓦斯突出矿井石门揭煤探索出一条安全、快速的技术途径。
