Integrated Coastal Zone Management (ICZM) is a complex multi-actor issue. Staff members of Cochin University (CUSAT) from India and colleagues from the Netherlands interpreted this issue as a challenge to initiate and enhance multi-stakeholder dialogue and action and the idea was born to produce a Visual Problem Appraisal (VPA). VPA is a film-based learning system that aims to induce social learning, to increase problem and policy analysis competencies, to reduce self-referentiality, to increase commitment for concerned stakeholders, and to enhance intersubjective consensus. In 2003 Indian and Dutch university staff members and Indian filmmakers produced two documentaries and 23 films portraying the Keralite stakeholders in their natural environment, exposing their engagement with, and different perspectives on, ICZM. Although produced for formal education, the notion emerged that the VPA might as well work in the reality of ICZM in Kerala. It was a fascinating conversion of questioning the nature of some events and frictions that occurred during the production process. As critical incidents were attributed to various cultural disparities such as local/foreign, male/female, higher/lower status, the hypothesis was formulated that if producing the VPA had already set a deep impact; how about using it directly with involved stakeholders? This hypothesis was tested in 2004 in workshops with publics, ranging from CUSAT students to local stakeholders of the Thycattussery Panchayat. The process of producing and testing the VPA Kerala’s Coast was a complex and intriguing multidisciplinary and multicultural project. We wondered what made the project a success. Framing the project as a space of cultural communication gave guidance to the questions that articulated our search to understand the process we had been immersed in. In this article we describe the events and analyze critical incidents that occurred during the production and the use of the VPA. The outcome leads to valuable recommendations for international and intercultural teams working on similar production and research projects.  相似文献

Risk assessment is an essential component of genetic counseling and testing, and the accuracy of risk assessment is critical for decision making by consultands. However, it has been shown that genetic risk calculations may have high error rates in practice. Risk calculations for autosomal dominant disorders are frequently complicated by age-dependent penetrance and sensitivities of less than 100% in genetic testing. We provide methods of risk calculation for prototypical pedigrees of a family at risk for an autosomal dominant disorder with age-dependent penetrance. Our risk calculations include scenarios in which the sensitivity of genetic testing is less than 100%, and in which the sensitivity of genetic testing varies for different family members at risk. Our Bayesian methods permit autosomal dominant disease probabilities to be calculated accurately, taking into account all relevant information. Our methods are particularly useful for hereditary cancer syndromes, in which genetic testing can seldom achieve 100% sensitivity. Our methods can be applied to many different scenarios, including those where the sensitivity of genetic testing varies for different family members at risk.

Children apply various strategies to mentally solve multi-digit subtraction problems and the efficient use of some of them may depend more or less on numerical magnitude processing. For example, the indirect addition strategy (solving 72–67 as “how much do I have to add up to 67 to get 72?”), which is particularly efficient when the two given numbers are close to each other, requires to determine the proximity of these two numbers, a process that may depend on numerical magnitude processing. In the present study, children completed a numerical magnitude comparison task and a number line estimation task, both in a symbolic and nonsymbolic format, to measure their numerical magnitude processing. We administered a multi-digit subtraction task, in which half of the items were specifically designed to elicit indirect addition. Partial correlational analyses, controlling for intellectual ability and motor speed, revealed significant associations between numerical magnitude processing and mental multi-digit subtraction. Additional analyses indicated that numerical magnitude processing was particularly important for those items for which the use of indirect addition is expected to be most efficient. Although this association was observed for both symbolic and nonsymbolic tasks, the strongest associations were found for the symbolic format, and they seemed to be more prominent on numerical magnitude comparison than on number line estimation.  相似文献

This article sheds light on the debate regarding political trust and protest activity. The debate boils down to the question whether trust in politics is positively or negatively related to protest activity. We exploit a dataset encompassing data on about 9,000 demonstrators spread over seven European countries. These demonstrators' trust in their parliaments varies widely, ranging from trustworthy capable, to corrupt incapable. We examine the diverging sociodemographic profiles and motivational dynamics that turn distrusting and trusting citizens into demonstrators. We hypothesize and show that distrusting demonstrators turn their back to institutionalized politics; for them, demonstrating substitutes the party politics they distrust. For trusting demonstrators, demonstrating supplements party politics. Trusting and distrusting demonstrators also differ considerably in terms of motivation. Distrusting demonstrators are stronger motivated to demonstrate than trusting demonstrators. Moreover, while political cynicism amplifies the motivation of distrusting demonstrators, it suppresses the motivation of trusting demonstrators. We conclude that the question to be answered is not so much whether people who engage in protest activity trust or distrust their political elites, but rather who the trusting and distrusting protesters are and why they protest.  相似文献

This article studies how Dutch military personnel respond to austerity-related discontent. Based on the online survey (N = 579) conducted among military personnel we investigate 4 response strategies to austerity measures applied in the Dutch armed forces: voice (collective protest), exit (leaving the organization), silence (deliberately deciding not to protest), and neglect (engaging in anti-organizational behavior). We focus on how personnel combine these strategies and apply cluster analysis to identify 6 typical response patterns that we label as protesters, escapers, quiescents, conformers, obstructionists and combaters. We investigate how personal characteristics and perception of unique military environment influence the response of military personnel. We conclude that clusters we described are not only distinct in their behavior—their personal characteristics and perceptions differ as well.  相似文献
