基于层次分析法的南疆旅游纪念品价值评价

南疆地处新疆天山以南,旅游纪念品资源丰富,有鲜明的地方特色和独特的民族风格,但现有旅游纪念品开发深度不够,影响了游客旅游质量.利用层次分析法（AHP）对南疆旅游纪念品资源价值、商品属性和市场潜力进行评价,认为资源价值在旅游纪念品评价中权重最高,商品属性和市场潜力是影响纪念品价值的重要因素,并针对评价体系和综合评价结果对南疆旅游纪念品进行价值分析.     

项目环评在化工企业厂区平面布置优化中的作用

以河南某化工企业为例,从厂区功能区划分、主要污染源分布、排水路线制定、卫生和安全防护等方面对其进行厂区平面布置合理性分析,通过分析评价各关键因素对周围环境及敏感点的影响程度大小对厂区平面布置进行适当调整和优化。由案例可知,项目环评不仅能够有效削减工业污染物排放对厂区人员和附近敏感点的影响,而且能够有效反馈厂区平面设计中存在的不足,通过优化调整降低铁路、高压线、环境敏感点跨辖区搬迁等限制条件对项目主要生产功能区布置的影响,提高企业生产中的卫生安全和风险防护水平,降低企业环保投入,实现经济和环保效益协调发展。     

Mapping Human and Social Dimensions of Conservation Opportunity for the Scheduling of Conservation Action on Private Land

Abstract Spatial prioritization techniques are applied in conservation‐planning initiatives to allocate conservation resources. Although typically they are based on ecological data (e.g., species, habitats, ecological processes), increasingly they also include nonecological data, mostly on the vulnerability of valued features and economic costs of implementation. Nevertheless, the effectiveness of conservation actions implemented through conservation‐planning initiatives is a function of the human and social dimensions of social‐ecological systems, such as stakeholders’ willingness and capacity to participate. We assessed human and social factors hypothesized to define opportunities for implementing effective conservation action by individual land managers (those responsible for making day‐to‐day decisions on land use) and mapped these to schedule implementation of a private land conservation program. We surveyed 48 land managers who owned 301 land parcels in the Makana Municipality of the Eastern Cape province in South Africa. Psychometric statistical and cluster analyses were applied to the interview data so as to map human and social factors of conservation opportunity across a landscape of regional conservation importance. Four groups of landowners were identified, in rank order, for a phased implementation process. Furthermore, using psychometric statistical techniques, we reduced the number of interview questions from 165 to 45, which is a preliminary step toward developing surrogates for human and social factors that can be developed rapidly and complemented with measures of conservation value, vulnerability, and economic cost to more‐effectively schedule conservation actions. This work provides conservation and land management professionals direction on where and how implementation of local‐scale conservation should be undertaken to ensure it is feasible.     

航空安全文化运行模式研究

依据安全文化基本原理,对航空安全文化模式进行系统化设计。将安全精神文化、制度文化、行为文化和物态文化4个子系统置于安全文化模式的大系统中,综合分析各子系统之间的互动关系及其对管理模式变革的影响。结合航空安全管理的特点,设计安全文化运行机制的结构框架。通过分析安全文化模式的运行过程和运行功能模块,实现航空安全文化模式的动态管理,使零散的安全文化模式得以系统化。航空安全文化模式的构建为航空运输企业建立了一个程序化、系统化、动态循环的管理过程,并以持续改进的思想指导企业系统地实现其安全目标。     

Modeling the exposure of children and adults via diet to chemicals in the environment with crop-specific models

Exposure to chemicals via diet is a major uptake pathway for many compounds but is often estimated in a rather generic way. We use a new model framework (NMF) with crop-specific models to predict the dietary intake by 4-5-year-old children and 14-75-year-old women of three environmental compounds from their background concentrations in soil and air. Calculated daily intakes of benzo(a)pyrene and 2,3,7,8-TCDD are in good agreement with measured results from diet studies. The major source of both compounds in human diet is deposition from air. Inhalation of air and ingestion of soil play a minor role. Children take up more than twice the amount than adults per kg bodyweight, due to higher consumption per kg bodyweight. Contrary, the methods for indirect human exposure suggested in the Technical Guidance Document (TGD) for chemical risk assessment in the EU lead to overprediction, due to unrealistic consumption data and a false root model.

Domestic or imported? An assessment of carbon footprints and sustainability of seafood consumed in Australia

The distance between where food is produced and consumed is increasing, and is often taken as evidence of an unsustainable global food system. Seafood is a highly traded commodity yet seafood sustainability assessments do not typically consider the impacts of the movement of products beyond the fishery or farm. Here we use life cycle assessment to examine the carbon footprint of the production and distribution of select seafood products that are consumed in Australia and determine differences in the sustainability of imports and their domestically produced counterparts. We found that the distance food is transported is not the main determinant of food sustainability. Despite the increased distance between production and consumption, carbon footprints of meals from imported seafood are similar to meals consisting of domestically produced seafood, and sometimes lower, depending on the seafood consumed. In combining LCA with existing seafood sustainability criteria the trade-offs between sustainability targets become more apparent. Carbon ‘footprinting’ is one metric that can be incorporated in assessments of sustainability, thereby demonstrating a broader perspective of the environmental cost of food production and consumption.
