Environmental evaluation for workplace violence in healthcare and social services

PROBLEM: Federal policy recommends environmental strategies as part of a comprehensive workplace violence program in healthcare and social services. The purpose of this project was to contribute specific, evidence-based guidance to the healthcare and social services employer communities regarding the use of environmental design to prevent violence. METHOD: A retrospective record review was conducted of environmental evaluations that were performed by an architect in two Participatory Action Research (PAR) projects for workplace violence prevention in 2000 and, in the second project in 2005. Ten facility environmental evaluation reports along with staff focus group reports from these facilities were analyzed to categorize environmental risk factors for Type II workplace violence. RESULTS: Findings were grouped according to their impact on access control, the ability to observe patients (natural surveillance), patient and worker safety (territoriality), and activity support. DISCUSSION: The environmental assessment findings reveal design and security issues that, if corrected, would improve safety and security of staff, patients, and visitors and reduce fear and unpredictability. IMPACT ON INDUSTRY: Healthcare and social assistance employers can improve the effectiveness of violence prevention efforts by including an environmental assessment with complementary hazard controls.     

The concept of participatory local sustainability projects in seven Chinese villages

SUCCESS was a scientific, multi-disciplinary case study of seven selected villages in China, coordinated by the Viennese research institute Oikodrom in which I have been a team member for 6 years. We assembled an international team of researchers to work together with local team leaders with the aim of involving village dwellers in a sustainability negotiation process. The project had a strong bottom-up approach, combined with top-down elements. Using participatory research methods, village teams discussed and developed ideas for concrete sustainability-oriented projects in their villages. By the end of the 3-year study of SUCCESS, equipped with the seeds of a multiple-scenario building process and the appropriate funding, each of the seven case study villages had generated ideas for local sustainability-oriented projects and put them into practice. The outcome of this participatory process is manifold. One major impact of the implementation of local projects was their visibility which was crucial for the village dwellers' confidence and their motivation to become engaged in a decision making process. The experience of their successful participation in a decision making process empowered them for self-organisation processes or a civil society process. The small projects offered interesting theoretical insights into how local contexts impact upon village dweller's decision on appropriate sustainability interventions. How they are as well in line with characteristics of different types of villages that were carried out within the study will be shown in this article.

The Tea Party versus Agenda 21: local groups and sustainability policies in U.S. cities

As local governments have moved toward adopting sustainability policies, there have been some cases where local Tea Parties have emerged as aggressive and strident opponents of such changes. Looking broadly at the Tea Party movement across the United States and systematically measuring its influence in urban America, we assess each Tea Party chapter’s capacity – its ability to convert resources into meaningful political advocacy. Data is derived from surveys of political elites in 50 cities as well as from determining the level of sustainability programming in each of these same cities. Evidence demonstrates that the Tea Party has not had a significant impact on city policymaking in the area of sustainability. Rather, the typical Tea Party chapter appears to be at best a modest presence in local politics.     

Reinventing the bicycle: how calculative practices shape urban environmental governance

The concept of sustainability transitions has become increasingly prominent in academic and policy discourses during recent decades, but the importance of the link between knowledge-producing epistemic practices and urban governance has been underappreciated in this discourse. Based on a case study of cycling in Copenhagen between 1900 and 2015, and drawing upon a governmentality-inspired analytical framework, this research demonstrates that transformative governance may be initiated by epistemic practices that render urban systems visible in other ways. Urban cycling has been reconstructed over time in Copenhagen as a traffic safety ‘problem’, a component of the experiential and liveable city, and a health-producing (and hence economically valuable) regional transport mode. The research findings emphasise that epistemic practices can provide a powerful stimulus for creating changes in urban governance. The results also provide support for initiatives to broaden the terms of academic debate on sustainability transitions.

水利旅游吸引力评价模型与实证研究

水利旅游是水利经济的新兴增长点,吸引力评价是旅游开发的基础性研究。借鉴引力理论,构建了由25个指标组成的水利旅游吸引力评价指标体系,运用AHP—PCA—Borda主客观组合评价法,对我国水利旅游吸引力进行了实证评价。结果表明,水利旅游吸引力地区不平衡,江苏、广东、山东、湖北、河南、浙江、湖南、北京和江西等省水利旅游吸引力较强,西部省份和处于我国版图中轴线附近的省份水利旅游吸引力较弱。
