广州市城市生态用地空间冲突与生态安全隐患情景分析

生态安全隐患区域的空间检测和获取对城市生态安全保护起到重要的作用。论文利用智能计算模型和空间分析技术,对广州市城市生态用地空间冲突与生态安全隐患进行了多情景模拟和分析。研究表明：① 空间冲突区域主要分布在城市边缘区。在城市生态用地占广州市总面积的15%、30%和50%情景下,分别占空间冲突总面积的95.40%、86.28%和77.45%,白云、花都、天河和番禺是空间冲突发生的主要区域。与之相反,城市核心区冲突区域面积所占比例逐渐增加。在50%情景时,空间冲突区域面积急剧增加,广州市城市生态用地控制指标面临着巨大的空间冲突压力。② 城市生态安全隐患区域主要分布在城市边缘区,在50%情景时,城市边缘区的隐患区域面积占隐患区域总面积的74.13%,白云区和花都区是生态安全隐患区域分布最集中的区域。而位于城市核心区的隐患区域,面临着更大的生态安全压力。研究结果可为城市生态安全的监控和预警提供参考,为城市生态保护提供可借鉴的方法和分析工具。     

责任矩阵在隐患排查治理中的应用

隐患排查治理是企业安全管理的主线,排查治理对象除人的不安全行为、物的不安全状态和不良的工作环境外,更应侧重于管理缺陷。针对目前管理缺陷排查治理方法论研究较少的问题,将项目管理工具—责任矩阵引入隐患排查体系。结合安全管理的特点,建立了隐患排查治理责任矩阵流程和应用准则,并通过某隐患排查治理责任矩阵的建立和应用对该方法进行了验证。研究表明,责任矩阵便于查找隐患背后的管理缺陷,可推动企业由下向上逐步完善安全生产责任制,对持续提升企业安全生产管理水平具有一定指导意义。     

Retiring: Role identity processes in retirement transition

Retirement transition has become a prolonged process of adaptation, including changes in role identity. However, there is a dearth of research on the process by which retirees cope with the role transition, including how pre-retirement role identities shape the transition, the forms of identity work undertaken by retirees, and the unfolding nature of retirement transition. In an in-depth qualitative examination of the transition process, we identify pre-retirement role identity profiles based on work and nonwork role identities. We then examine how pre-retirement role identities influence the transition process, including the nature of identity work in transition and the transition pathways demonstrated by retirees. Our findings provide insights into strengths and limitations afforded by pre-retirement identities: They facilitate agentic coping in which retirees shed old and adopt new identities but also impose inertia and prolong the transition until identity crises force the retirees to undergo identity exploration and adoption of new identities.

The measurement of place attachment: Personal,community, and environmental connections

Place attachment has been researched extensively in the social and behavioural sciences over the past two decades. However, it is challenging for researchers to assimilate the mixed messages presented in the place attachment literature and to understand the multiple place attachment terms. In this study, a four-dimensional model of rural landholder attachments to their natural resource management region was conceptually and empirically developed with the aim of developing an integrated approach to the measurement of place attachment that clearly distinguishes between different elements of place scholarship. A 29-item place attachment scale with the dimensions of place identity, place dependence, nature bonding, and social bonding was tested on a random sample of rural landholders in the Adelaide and Mount Lofty Ranges in South Australia (N = 320). The majority of respondents were male (69.3%) and the average age was 59 years. The scale was reduced to 20-items and then administered simultaneously and in the same response format to rural landholders in two other areas of South Australia: the Northern and Yorke region (N = 664) and South Australian Murray-Darling Basin region (N = 659). In both studies, the majority of respondents were male (85%) and the average age was 55 years. Exploratory factor and reliability analyses of Adelaide and Mount Lofty Ranges and Northern and Yorke datasets produced a five-dimensional model of place attachment with high reliabilities. Social bonding divided into the constructs of family bonding and friend bonding. The refined five-dimensional model was then examined for convergent validity, with moderate but significant correlations found between individual attachment constructs and dependent variables expected to be related to the construct, such as place identity and length of residence, and nature bonding and time currently spent in nature. We used confirmatory factor analysis to test the goodness-of-fit of the South Australian Murray-Darling Basin (SAMDB) dataset to the proposed five-dimensional model and then compared its fit to the traditional two-dimensional model of place identity and place dependence. The five-dimensional model provided moderate fit for the SAMDB data. We conclude with a discussion of the validity and reliability of the five-dimensional model and its future role in place attachment research.     

Conservatism vs. conservationism: differential influences of social identities on beliefs about fracking

ABSTRACT

Although recent expansions in hydraulic fracking operations across the United States have led to greater news coverage and attention from the public, overall understanding remains fairly low. For some, relevant social identities, including environmental or political, may provide a short cut to becoming informed about fracking, or to determining what they believe about it and how that influences their positions on fracking policies. Social identity influence frameworks provide an approach to understanding the relationships between belief and identity, which this study investigates through its affiliational and attitudinal components. National survey data are used to model pathways from environmental and political identities to beliefs about risks associated with fracking. Environmental attitudes significantly predicted belief that fracking has health risks, and mediated a relationship from environmental group affiliation, but environmental information was not significant. Ideology had direct and indirect effects, through partisan media use, while partisanship had direct effects on beliefs about environmental risks.     

柴达木盆地盐类资源成矿构造环境及成矿预测

运用区域地质资料和地球重力测量资料的分析成果,对柴达木盆地新生代地层沉积建造的空间位置和基本构造形式进行了讨论;用实验对比和地质概化的方法,建立了新生代盆地的构造边界和构造系统;用地球动力成矿和层位耦合成矿的规律说明,新生代盆地内部存在共轭成矿作用,并可用来预测成盐成矿地段和筛选寻矿找矿靶区,为中国大陆盆地的盐类矿产资源的开发和研究提供依据。根据柴达木盆地基底构造的分析,在第四纪成矿作用的基础上,在新生代地层深部寻找新的盐类矿床是大有前景的。依据成矿环境条件,圈定出5个盐类矿床的成矿构造带,是今后找矿勘探的靶区及成矿远景地带。
