Perceptions of the security and attractiveness of urban parking lots

This study concerns design features of urban parking lots which can increase the perception of such areas as both safe and attractive. College students evaluated the attractiveness and perceived security associated with 180 scenes of parking lots adjacent to commercial and multi-family residential structures in Atlanta and Athens, Georgia, U.S.A. High intergroup correlations (r > 0·90) indicated the reliability of evaluations of both perceived features. Regressions of physical features on perceived security ratings and attractiveness ratings yielded highly predictive models (R² = 0·76 and 0·80, respectively). For both sets of ratings a Maintenance and Design factor accounted for the most variance. Although attractiveness ratings were higher as the total amount of vegetation increased in a scene, security was in general rated higher only when vegetation was well maintained and appeared to be installed as part of a landscape design. Attractiveness was generally higher for multi-family residential scenes than for commercial scenes. Perceived security was higher for frontal views of structures, especially when entrances were proximate to the viewer. Research implications are discussed in terms of the impact of natural features in urban areas for increasing attractiveness and reducing fear of crime.     

Use of Physical Sciences in Support of Environmental Management

Offshore drilling for oil and gas has been conducted since the early 1900s. Oil and gas under the seabed continue to be an important part of the energy resources of the United States. The need to balance the value of these resources against the potential for environmental damage is an important concern. This article explains why and how the Minerals Management Service (MMS) of the US Department of the Interior uses research in physical sciences to help fulfill its environmental goals, and it provides background information on the role of physical sciences in decision-making for Outer Continental Shelf (OCS) oil, gas, and other minerals development. Established in the 1970s, the MMS Environmental Studies Program is a highly focused marine research program designed to provide the environmental information necessary for OCS energy and nonenergy minerals planning and development activities. The physical sciences research supported by MMS includes physical oceanography, oil-spill risk analyses, atmospheric sciences, and sand and gravel studies. Instead of giving a comprehensive review on physical sciences research in MMS, this article presents sample MMS studies and illustrates how these studies are utilized to support decision-making in environmental management.Published online Note: This version was published online in June 2005 with the cover date of August 2004.

Subnational government and EIA in the developing world: Bureaucratic strategy and political change in Rio de Janeiro,Brazil

EIA has been instituted in developing countries in the last decade largely in response to outside pressures. Governments have been quick to initiate reforms rather than jeopardize projects that might be key to national development plans. At the subnational level, most projects are not financed by foreign aid. The application of EIA at this level is often the result of pressure exerted on policy elites by the bureaucracy. This paper describes the reorganization of environmental protection agencies in the state of Rio de Janeiro in Brazil. This reorganization provided the setting for a bureaucratic initiative on EIA. The authors also analyze two cases in which EIA was applied unsatisfactorily and comment on the political realites of implementing EIA at the subnational level.     

(Why) did Desertec fail? An interim analysis of a large-scale renewable energy infrastructure project from a Social Studies of Technology perspective

ABSTRACT

In 2009 the Desertec Industrial Initiative (DII) was founded by several, predominant German enterprises. The objective of DII was to organise the conditions for the realisation of the Desertec idea, which aimed to both (a) supply Europe, in a large-scale manner, with electricity produced in solar power plants in North Africa and the Arabic peninsula and (b) contribute to the self-supply of the Middle East North Africa region (MENA). Protagonists of the desert energy idea saw this megatechnic project as a starting point for a new trans-Mediterranean EU-MENA union, critics in contrast as a neo-colonial project. Disputes over the adequate interpretation and implementation of the Desertec idea broke out from the beginning. In 2014/2015, the media talked of the failure of DII and of the Desertec concept. The majority of the members left DII at the end of 2014. On the other hand, in some MENA countries renewables are playing a crucial role in securing the future of the energy sector. This paper analyses the development of DII and the Desertec idea by using concepts from Social Studies in Technology, and especially by the multi-level perspective approach in Transition Studies. It shows how the interplay of different factors, such as technological developments, entrepreneurial performances and political processes, lead to internal conflicts and the non-realisation – up to now – of related large-scale energy projects. As an important aspect of the paper, different understandings of the future of our energy supply and of North–South relations are presented in detail.     

A SYSTEMS RESOURCES APPROACH TO CITIZEN PARTICIPATION: THE CASE OF THE CORPS OF ENGINEERS1

ABSTRACT: The thesis of this paper is that the citizen participation process provides necessary, but not sufficient conditions to affect substantive change in federal water resource management agencies' planning and decisionmaking. That is, in its present form, the citizen participation process has been observed to occur outside of the normal decision arenas of federal resource management agencies. The paper reviews concepts of citizen participation and defines some theoretical problems inherent with them. Then, a strategy for the structuring of a citizen participation process is proposed. This strategy is based upon the notion that citizen support for federally sponsored programs are essential if such projects are to be implemented. Therefore, an approach which integrates citizen valves with those held by other institutions and the agency is suggested. In conclusion, the relevancy of actively developing and including citizen input to the water resource planning process is illustrated by a discussion of three cases of the Corps of Engineers and Urban Studies planning process, in different metropolitan regions.

Knowledge for environmental governance: probing science–policy theory in the cases of eutrophication and fisheries in the Baltic Sea

How science and policy interact has been a major research focus in the International Relations (IR) tradition, using the epistemic community (EC) concept, as well as in the alternative perspective of Science and Technology Studies (STS). Should science be autonomous and as apolitical as possible in order to ‘speak truth to power’, as suggested by EC or should the inevitable entanglement of science and politics be accepted and embraced so as to make advice more conducive to negotiating the explicit travails of political decision-making as suggested by STS? With this point of departure, we compare similarities and differences between science–policy interactions in the issue areas of eutrophication and fisheries management of the Baltic Sea. To examine how knowledge is mobilised, the concepts of ‘uncertainty’ and ‘coherence’ are developed, drawing on both EC and STS thinking. We then reflect on the explanatory value of these approaches in both cases and discuss how a separation of science and policy-making in the pursuit of achieving scientific consensus leads to ineffectual policies. Drawing on STS thinking, we urge for a re-conceptualisation of coherence in order to accommodate a more reflexive practice of science–policy interactions.     

Scenario Development as a Basis for Formulating a Research Program on Future Agriculture: A Methodological Approach

To increase the awareness of society to the challenges of global food security, we developed five contrasting global and European scenarios for 2050 and used these to identify important issues for future agricultural research. Using a scenario development method known as morphological analysis, scenarios were constructed that took economic, political, technical, and environmental factors into account. With the scenarios as a starting point future challenges were discussed and research issues and questions were identified in an interactive process with stakeholders and researchers. Based on the outcome of this process, six socioeconomic and biophysical overarching challenges for future agricultural were formulated and related research issues identified. The outcome was compared with research priorities generated in five other research programs. In comparison, our research questions focus more on societal values and the role of consumers in influencing agricultural production, as well as on policy formulation and resolving conflicting goals, areas that are presently under-represented in agricultural research. The partly new and more interdisciplinary research priorities identified in Future Agriculture compared to other programs analyzed are likely a result of the methodological approach used, combining scenarios and interaction between stakeholders and researchers.     

Pedagogy for Sustainability Science: Case-Based Approaches for Interdisciplinary Instruction

Sustainability science represents a fundamental shift in the nature of research on environmental problems, calling for specialists to expand beyond their disciplinary perspectives in order to cooperate together to understand and address systemic problems. This shift demands a corresponding shift in education in order to equip students with the skills, theories, and methods they need to address contemporary challenges. We argue that case studies are a productive pedagogical approach to teaching about sustainability and teaching for sustainability. Case-based approaches equip students to encounter complexity, manage uncertainty, and generate innovative strategies. In laying out of the pedagogical challenges inherent in sustainability education, we highlight opportunities and demands for environmental communication scholars to contribute to the emerging discipline of sustainability science.
