A Global Model Tracking Water, Nitrogen, and Land Inputs and Virtual Transfers from Industrialized Meat Production and Trade

Rising populations and incomes throughout the world have boosted meat demand by over 75% in the last 20years, intensifying pressures on production systems and the natural resources to which they are linked. As a growing proportion of global meat production is traded, the environmental impacts of production become increasingly separated from where the meat is consumed. In this paper, we quantify the use of three important resources associated with industrial livestock production and trade—water, land, and nitrogen—using a country-specific model that combines trade, agronomic, biogeochemical, and hydrological data. Our model focuses on pigs and chickens, as these animals are raised predominantly in intensive systems using concentrated, compound feeds. The results describe the geographical patterns of environmental resource use due to meat production, trade, and consumption. We show that US feed, animal, and meat destined for export require almost as much nitrogen and land, and 20% more water, than products destined for domestic consumption. Model results also demonstrate that among various production factors, improvements in crop yields and animal feed conversion efficiencies result in the most significant reductions in environmental harm. By explicitly tracking the externalities of meat production, we hope to bolster suppliers’ accountability and provide better information to meat consumers.

基于OSHMS的煤矿模糊综合安全评价管理模型的建立

针对目前我国煤矿企业安全管理现状,以一种全新的思路结合职业安全健康管理体系(OSHMS)的系统化体系结构及其先进之处,以预防为主,持续改进为动力,建立了基于生产过程的绩效测量、人员职责分配、运行控制和风险管理为核心的4个主要因素的安全评价管理模型;并以此为指导建立安全评价指标体系框架,运用模糊综合安全评价的方法对指标体系进行合成;最后,结合矿井生产过程中的供电系统,对淮南潘三矿现场进行实例应用,证明其可行性。该管理模型对煤矿企业安全管理有推广和借鉴意义,可望为煤矿企业通过安全管理实现科技兴安提供一种更可靠,更有效的安全管理方法。     

江苏省危险化学品生产状况调查分析及监管对策

根据《危险化学品名录》,分析江苏省取得危险化学品安全生产许可证的1774家企业的化学品种类、数量、生产企业类型分布情况.结果表明,江苏省危险化学品生产企业在地域分布上苏南多于苏北;化工、建材行业的危险化学品生产企业所占比例较高;危险化学品涉及除爆炸品外的6大类,达3 790种,以生产易燃液体的企业数目为最多;有31家企业生产10种以上危险化学品.笔者建议,通过评估摸清企业安全生产状况,严格控制危险化学品企业安全生产许可证发放,实现危险化学品运输企业的动态管理,建立安全监测预警技术平台.

基于产生来源的固体废物鉴别研究

通过对美国、欧盟和日本的固体废物定义和范围,以及已完成的固体废物鉴别实例的研究,指出固体废物鉴别的关键点在于产生来源分析。提出依据产生来源,固体废物可以分为丧失原有使用价值的物质、生产过程中产生的副产物类物质、环境治理和污染控制过程中产生的物质、其他类物质4大类。如果待鉴别物质的产生来源属于该4大产生来源中的任何一类,则其属于固体废物。     

单轴应力对煤自燃特性参数和导热系数的影响研究

为探究单轴应力作用下煤氧化和传热特性,利用自制荷载加压煤自燃特性参数测定装置对炉体内长焰煤煤样进行程序升温。结合程序升温过程中煤临界温度Tc和Tg,对其进行阶段划分:阶段1为30℃~Tc;阶段2为Tc~Tg。计算了不同单轴应力下2个阶段煤表观活化能和平均耗氧速率。根据能量守恒得出程序升温过程煤导热系数随温度的变化,进一步分析煤导热系数与单轴应力的关系。结果表明:阶段1单轴应力为4 MPa时为临界轴压,煤表观活化能最大,平均耗氧速率最小;阶段2煤表观活化能和平均耗氧速率随单轴应力增大均呈抛物线变化,单轴应力为2.7 MPa时为临界轴压,煤表观活化能最大,平均耗氧速率最小;阶段1和2煤导热系数随温度升高均先减小后增大,并且煤导热系数随单轴应力增大呈三次函数变化。     

Free market ideology and deregulation in Colorado’s oil fields: Evidence for triple movement activism?

Unconventional oil and gas extraction (UOGE) has spurred an unprecedented boom in onshore production in the US. Despite a surge in related research, a void exists regarding inquiries into policy outcomes and perceptions. To address this, support for federal regulatory exemptions for UOGE is examined using survey data collected in 2015 from two Northern Colorado communities. Current regulatory exemptions for UOGE can be understood as components of broader societal processes of neoliberalization. Free market ideology increases public support for federal regulatory exemptions for UOGE. Perceived negative impacts do not necessarily drive people to support increased federal regulation. Utilizing neo-Polanyian theory, interaction between free market ideology and perceived negative impacts is explored. Free market ideology appears to moderate people’s views of regulation: increasing the effect of perceived negative impacts while simultaneously increasing support for deregulation. To conclude, the ways in which free market ideology might normalize the impacts of UOGE activity are discussed.
