矿山资源环境一体化思想框架及其应用研究

矿山资源和矿山环境是同一事物的两个侧面。矿山资源是矿山环境的组成部分,是有经济价值的环境;矿山资源的开发过程同时也是环境的改变过程,由矿山资源开发而引起的环境问题,往往是资源不合理利用的结果;矿山环境污染物(如固体废弃物)存在二次开发或资源化的可能。重点探讨矿山资源环境一体化思想框架,并针对广西刁江流域矿山资源开发过程中出现的资源浪费与严重的环境问题,提出了可持续开发对策。

Does office space occupation matter? The role of the number of persons per enclosed office space,psychosocial work characteristics,and environmental satisfaction in the physical and mental health of employees

The study examined the effects of office space occupation, psychosocial work characteristics, and environmental satisfaction on physical and mental health of office workers in small‐sized and open‐plan offices as well as possible underlying mechanisms. Office space occupation was characterized as number of persons per one enclosed office space. A total of 207 office employees with similar jobs in offices with different space occupation were surveyed regarding their work situation (psychosocial work characteristics, satisfaction with privacy, acoustics, and control) and health (psychosomatic complaints, irritation, mental well‐being, and work ability). Binary logistic and linear regression analyses as well as bootstrapped mediation analyses were used to determine associations and underlying mechanisms. Employee health was significantly associated with all work characteristics. Psychosocial work stressors had the strongest relation to physical and mental health (OR range: 1.66–3.72). The effect of office space occupation on employee health was mediated by stressors and environmental satisfaction, but not by psychosocial work resources. As assumed by sociotechnical approaches, a higher number of persons per enclosed office space was associated with adverse health effects. However, the strongest associations were found with psychosocial work stressors. When revising office design, a holistic approach to work (re)design is needed.

Participatory Framework for Assessment and Improvement of Tools (ParFAIT): Increasing the impact and relevance of water management decision support research

This paper proposes the Participatory Framework for Assessment and Improvement of Tools (ParFAIT) as a way to address low uptake of Water Resources Systems Optimization (WRSO) tools. ParFAIT is a transdisciplinary process conducted in five stages, two of which are participatory modeling (PM) exercises. Herein we describe the framework, introduce our candidate tool- Multiobjective Evolutionary Algorithm (MOEA)-assisted optimization, and present the results of our first PM workshop. MOEA-assisted optimization has been put forth as a planning and decision making aid for utilities facing a large number of decisions and highly uncertain futures. The PM workshop, designed to solicit input on a tool testbed, was held in February 2015 with representatives from six Front Range, Colorado, water utilities. Our results include an expanded characterization of the decision making landscape, feedback on water utility decisions and performance goals commonly employed in WRSO studies, and new questions that warrant future investigation by researchers.     

Personal resources and political uprooting: The Israeli experience.

The authors assessed distress in Israeli society before and after Israel’s disengagement from Gaza and the northern West Bank during the summer of 2005. Random samples of 701 Israelis residing in various parts of Israel (Study 1) and 246 Israelis residing in Gaza and the northern West Bank who were to be uprooted (Study 2) were interviewed by telephone several weeks before the disengagement (T1), with 462 and 124 of these respondents, respectively, reinterviewed several weeks after the disengagement (T2). Anxiety related to the national and security situation was lower at T2 than at T1 in both studies. A personal resource, namely mastery–optimism, contributed negatively to both anxiety and hostility before the disengagement in both studies. In Study 1, it also predicted lower postdisengagement anxiety. The findings underscore the importance of mastery–optimism in the adjustment to threatening political events such as forced uprooting.

Comparison of potential water supply and demand in Taiwan

The authors estimated the potential water supply in Taiwan based on hydrologic and water resource data sets pertaining to 233 rainfall stations, 145 stage stations and 109 reservoirs. The comparison between potential water supply estimates and predicted water demand indicated a slight water shortage, even though Taiwan normally receives a large amount of rainfall. This predicted water shortage likely occurred due to the uneven distribution of rainfall in Taiwan. Taken together, the results of this study demonstrate the importance of conservation of forests and paddy fields for the maintenance of base flow and effective management of reservoirs in Taiwan.
