Pressure probe compensates for dimensional tolerance variations

Flexible, compressible spring-loaded pressure probe measures the static pressure between the rotor stages on an axial-flow fuel pump. This probe is used in installation where a drilled static pressure tap or a rigid impulse tube cannot be used. Its parameters must be specially determined for each installation

The surprising place of cognitive psychology in the work of F.A. Hayek

In 1920, when Hayek was a student, he wrote a manuscript on cognitive psychology, which was published in 1952 as The Sensory Order. From the 1920s to the early 1940s Hayek developed his business cycle theory. The perceptions of economic agents play a central part in this theory. Contrary to what one might expect, however, none of the mental mechanisms of his earlier theory on perception and cognition play a part in his economics. The answer to this apparent anomaly lies in the programmatic character of the whole of Hayek''s work, and in the specific way in which his ideas evolved. His psychology played a prominent role in the later development of his ideas. If Hayek''s psychology influenced his early economics, it did so indirectly, by shaping his methodology. However, there may also be a common influence underlying both Hayek''s psychology and his economic methodology.Economics ;

Agricultural strategy development in West Africa: The false promise of participation?

"Participatory approaches are an increasingly prominent technique for designing agricultural strategies within Sub-Saharan Africa. However, such approaches are frequently criticized for either not involving enough stakeholders or limiting the scope of their participation. By analyzing the role of stakeholder participation in the formulation of agricultural and rural development strategies in West Africa, this paper finds that a lack of broad-based participation in these strategies was not a major problem. Rather, the real challenge lies in transforming the outcomes of participatory processes into policies that can be feasibly implemented. The paper highlights why an emphasis on participatory processes can sometimes result in disappointment among stakeholders and discusses a range of measures to help overcome this dilemma.

Between conservationism, eco-populism and developmentalism: discourses in biodiversity policy in Thailand and Indonesia

"The present paper analyzes the role of discourse in conflicts concerning nature conservation in tropical countries. We focus on the contested question as to whether and to which extent local communities should be allowed to live and use resources inside protected areas. Applying the concepts of belief-systems, story-lines and discourse coalitions, we analyze two empirical case studies dealing with this conflict: The first case study is concerned with a policy process at the national level that aimed at passing a community forestry law in Thailand to make the establishment of community forests in protected areas possible. The second case study deals with the proposed resettlement of a village from the Lore Lindu National Park in Sulawesi, Indonesia. In both cases, three discourses could be observed: a conservationist discourse, an eco-populist discourse, and a developmentalist discourse. The case studies show that the conservationists and the developmentalists were able to form a discourse coalition, which was challenged by the proponents of the eco-populist discourse. The analysis also demonstrates that establishing story-lines in the discourse can lead to the neglect of facts and problems that do not fit in either discourse. The paper draws attention to the role of science in the different discourses and concludes that scientists should become more aware of the role they play in the different discourses."

Regional biotechnology regulations: Design options and implications for good governance

"Many developing countries are currently in the process of designing regulatory systems that should allow them to use genetically modified organisms (GMOs) for agricultural development, while also managing the food safety and environmental risks potentially associated with these technologies. Various regions of the developing world are seeking to establish regional systems of biotechnology regulation. However, considerable costs are associated with biotechnology regulation, and biosafety specialists are scarce. In addition, there is no consistent understanding of how regional systems of biotechnology regulation can be designed to be effective and efficient, while also fulfilling the principles of good governance, such as transparency, voice and accountability, control of corruption, and avoidance of special interest capture. There are a wide variety of possible regional approaches, differing with regard to the level of centralization, the scope of the regional system, the types of regional institutions and processes, and the types of financing mechanisms. Here, based on findings in the fields of environmental and fiscal federalism and transaction costs economics, we develop a conceptual framework for the assessment of regional systems of biotechnology regulation. The framework specifies design options and assessment criteria, and identifies major trade-offs and their mediating factors. We use the case of West Africa to illustrate this framework, and refer to the European Union for comparison. Our analysis indicates that involving regional experts, stakeholders and policy-makers in the design of a regional regulatory system will help fill knowledge gaps and generate conclusions regarding the trade-offs involved in regional biotechnology regulation." from Author's AbstractRegional biotechnology regulation, Regulatory systems, Transaction cost economics, European Union, Governance,
