Workplace response of companies exposed to the 9/11 World Trade Center attack: a focus‐group study

The terrorist attacks of 11 September 2001 (9/11) left workplaces in pressing need of a mental health response capability. Unaddressed emotional sequelae may be devastating to the productivity and economic stability of a company's workforce. In the second year after the attacks, 85 employees of five highly affected agencies participated in 12 focus groups to discuss workplace mental health issues. Managers felt ill prepared to manage the magnitude and the intensity of employees' emotional responses. Rapid return to work, provision of workplace mental health services, and peer support were viewed as contributory to emotional recovery. Formal mental health services provided were perceived as insufficient. Drawing on their post‐9/11 workplace experience, members of these groups identified practical measures that they found helpful in promoting healing outside of professional mental health services. These measures, consistent with many principles of psychological first aid, may be applied by workplace leaders who are not mental health professionals.     

我国生态功能区划的目标、原则与体系

阐述了我国开展生态功能区划的背景,分析了全国生态功能区划的基本目标和任务。以生态系统科学为基础,明确了开展生态功能区划的基本原则——生态系统完整性原则。在生态系统完整性原则下。定义系统、系统边界、系统等级和认识生态系统的尺度。对生态功能区划与自然区划、农业区划以及生态地域划分之间的联系与区别进行了分析,指出从单一要素的各种自然区划,到以整体生态系统为基础的生态功能区划是协调人与自然关系、寻求自然资源保护与人类对资源的永续利用之间的平衡的认识进步。在生态系统完整性原则上,提出了我国生态功能区划体系的框架。论述了流域在生态和社会经济方面的重要性。认为以大流域为基本区划单元的划分是构建我国生态功能区划的基本方式．“生态热点”地区规划是必要的、灵活的辅助手段．     

我国开展政策环评的必要性及其基本框架研究

政策环评对决策科学化和民主化具有重要意义，我国2014年修订的《环境保护法》也为开展政策环评提供了一定法律依据。然而，由于我国政治体制和决策模式与西方国家明显不同，政策环评不能照搬国外模式，必须基于自身国情探索中国模式。为此，本文对国际上比较有代表性的政策环评实践进行了总结，对我国开展政策环评的必要性进行了分析，并探讨了我国开展政策环评需要考虑的关键问题，包括政策环评的目的、对象、重点和程序等。具体而言，对于实施政策环评的目的，可表述为健全决策机制、促进环境公平和凝聚社会共识三个方面；对于评价对象，在广义上可包含目前环境影响评价法尚未覆盖的所有高层次决策，在狭义上可将政府部门制定的行政法规、规章和规范性文件等作为重点；对于评价重点，建议整合"以影响为核心"的战略环评和"以制度为核心"的战略环评两种类型的优点，兼顾影响评价和制度评价；对于评价程序，政策环评应基于完全理性决策模式，与政策过程充分融合，在不同阶段分别发挥不同作用。     

How have we,do we,and will we measure time perspective? A review of methodological and measurement issues

Despite the demonstrated importance of time perspective on key outcomes, its growing popularity, and its wide reach in terms of samples and disciplines, the construct has been plagued with definitional and measurement problems since its inception. Given the historical and current confusion regarding both conceptualization and operationalization, the purpose of this article is to provide an overview of methodological and measurement issues related to time perspective. Clearly, definitional and measurement clarity are critical for the success of future research. Through integrating the fragmented and eclectic time perspective literature fraught with ambiguity, we help to clarify measurement options and their psychometric evidence for future researchers. Specifically, we provide an in-depth comparison of four (and their offshoots) commonly used, scale-based measures of time perspective with respect to their dimensional content, psychometric properties, and validation evidence. We end with recommendations for time perspective research.     

Heterogeneity of farmers' preferences towards agri-environmental schemes across different agricultural subsystems

Specialised literature on the uptake of agri-environmental schemes (AES) has paid little attention to how this can be influenced by the different types of agricultural systems. This paper analyses the heterogeneity of farmers' preferences towards these schemes, distinguishing between different subsystems within the same agricultural system. We use the choice experiment method to analyse the case study of three olive grove subsystems in southern Spain, with the subsystems ranging from extensive to intensive. The results reveal inter- and intra-subsystem heterogeneity of farmers' preferences towards AES, both in general and specifically related to scheme attributes. A variety of factors appear to lie behind inter-subsystem heterogeneity, especially those associated with subsystem specificities (principally, the type of joint production). Likewise, numerous factors play a role in intra-subsystem heterogeneity, most of them related to farm/farmer socio-economic and physical characteristics. These findings will help in the design of more efficient AES.     

Public acceptance of large-scale wind energy generation for export from Ireland to the UK: evidence from Ireland

Although international trade in energy may offer a flexible and cost effective means by which European countries could meet their renewable energy targets, developers in the exporting nation can face local opposition for reasons which are not always clear. Using focus groups and a public survey, we contrast perspectives between local stakeholders and wind farm operators and investigate the community impacts associated with large-scale wind energy for domestic use and export from Ireland to the UK. Although the export of renewable energy from Ireland to the UK is currently on hold, our findings suggest that significant investment is required by the state and wind farm operators in better information provision, trust building, effective instruments to internalise wind farm externalities and co-management arrangements before Ireland can fully capture the benefits of wind exports to the UK.

Ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome: A theoretical framework

Objective To develop a theoretical framework for analysing ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome. Methods We applied Weinstein's Precaution Adoption Process (PAP) Model to the decision of whether or not to participate in prenatal screening for Down syndrome. The prenatal screening stage model was specified by reviewing the empirical literature and by data from seven focus group interviews with Dutch, Turkish and Surinamese pregnant women in the Netherlands. Results We identified 11 empirical studies on ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome. The focus group interviews showed that almost all stages and determinants in the stage model were relevant in women's decision-making process. However, there were ethnic variations in the relevance of determinants, such as beliefs about personal consequences of having a child with Down syndrome or cultural and religious norms. Discussion The prenatal screening stage model can be applied as a framework to describe the decision-making process of pregnant women from different ethnic backgrounds. It provides scope for developing culturally sensitive, tailored methods to guide pregnant women towards informed decision-making on participation or non-participation in prenatal screening for Down syndrome.
