ABSTRACTCommunities face “glocalized” ecosocial problems. Functional Community Organization bridges local problems with globalized issues, organizes community, and meets need. Models describe glocal linkages and their outcomes, but little is known of processes and challenges in organizing. This article qualitatively explores ecosocial organizing challenges in a Community Technology Center in a US city, which organized around e-waste and digital inequality. Findings indicate that Functional Communities may face challenges in organizing aims due to complexities in balancing need while concurrently addressing global problems and issues in structure, funding, and process. This may be mitigated through communication, focus, self-awareness, and reflexivity. 相似文献

I was teaching rhetoric at the University of Victoria when I received the ‘Quick Reference Guide: Assisting Students in Distress’, part of the university’s initiative to address the increasing problem of mental illness on university campuses. I immediately read a rhetoric that presented mental health as Madness, as something to be feared, a threat to the university, class and the individual. This short article is a brief rhetorical analysis of this Guide, and suggests that we must move beyond fear if we are to begin to address the mental health crisis on university campuses. 相似文献

This paper proposes a new approach to equilibrium selection in repeated games with transfers, supposing that in each period the players bargain over how to play. Although the bargaining phase is cheap talk (following a generalized alternating‐offer protocol), sharp predictions arise from three axioms. Two axioms allow the players to meaningfully discuss whether to deviate from their plan; the third embodies a “theory of disagreement”—that play under disagreement should not vary with the manner in which bargaining broke down. Equilibria that satisfy these axioms exist for all discount factors and are simple to construct; all equilibria generate the same welfare. Optimal play under agreement generally requires suboptimal play under disagreement. Whether patient players attain efficiency depends on both the stage game and the bargaining protocol. The theory extends naturally to games with imperfect public monitoring and heterogeneous discount factors, and yields new insights into classic relational contracting questions. 相似文献

In this paper, we provide probabilistic predictions for soccer games of the 2010 FIFA World Cup modelling the number of goals scored in a game by each team. We use a Poisson distribution for the number of goals for each team in a game, where the scoring rate is considered unknown. We use a Gamma distribution for the scoring rate and the Gamma parameters are chosen using historical data and difference among teams defined by a strength factor for each team. The strength factor is a measure of discrimination among the national teams obtained from their memberships to fuzzy clusters. The clusters are obtained with the use of the Fuzzy C-means algorithm applied to a vector of variables, most of them available on the official FIFA website. Static and dynamic models were used to predict the World Cup outcomes and the performance of our predictions was evaluated using two comparison methods. 相似文献

The Department of Homeland Security (DHS) characterized and prioritized the physical cross‐border threats and hazards to the nation stemming from terrorism, market‐driven illicit flows of people and goods (illegal immigration, narcotics, funds, counterfeits, and weaponry), and other nonmarket concerns (movement of diseases, pests, and invasive species). These threats and hazards pose a wide diversity of consequences with very different combinations of magnitudes and likelihoods, making it very challenging to prioritize them. This article presents the approach that was used at DHS to arrive at a consensus regarding the threats and hazards that stand out from the rest based on the overall risk they pose. Due to time constraints for the decision analysis, it was not feasible to apply multiattribute methodologies like multiattribute utility theory or the analytic hierarchy process. Using a holistic approach was considered, such as the deliberative method for ranking risks first published in this journal. However, an ordinal ranking alone does not indicate relative or absolute magnitude differences among the risks. Therefore, the use of the deliberative method for ranking risks is not sufficient for deciding whether there is a material difference between the top‐ranked and bottom‐ranked risks, let alone deciding what the stand‐out risks are. To address this limitation of ordinal rankings, the deliberative method for ranking risks was augmented by adding an additional step to transform the ordinal ranking into a ratio scale ranking. This additional step enabled the selection of stand‐out risks to help prioritize further analysis. 相似文献

Chemical alternatives assessment is a method rapidly developing for use by businesses, governments, and nongovernment organizations seeking to substitute chemicals of concern in production processes and products. Chemical alternatives assessment is defined as a process for identifying, comparing, and selecting safer alternatives to chemicals of concern (including those in materials, processes, or technologies) on the basis of their hazards, performance, and economic viability. The process is intended to provide guidance for assuring that chemicals of concern are replaced with safer alternatives that are not likely to be later regretted. Conceptually, the assessment methods are developed from a set of three foundational pillars and five common principles. Based on a number of emerging alternatives assessment initiatives, in this commentary, we outline a chemical alternatives assessment blueprint structured around three broad steps: Scope, Assessment, and Selection and Implementation. Specific tasks and tools are identified for each of these three steps. While it is recognized that on‐going practice will further refine and develop the method and tools, it is important that the structure of the assessment process remain flexible, adaptive, and focused on the substitution of chemicals of concern with safer alternatives. 相似文献

During the past decade scholars have noted growing ideological polarization between Democratic and Republican Party elites in the United States. This trend has occurred in a party system traditionally characterized as decentralized. This paper examines whether the trend towards partisan polarization noted by scholars at the national level has affected state party systems in similar ways. Are some state party systems more polarized than others? The paper uses a classification scheme of state party systems developed by David Mayhew to try to explain interstate differences in partisan polarization. The paper concludes that states with political environments that supported pragmatic and non-ideological traditional party organizations are less polarized in the modern era than states without such environments. 相似文献

In using survey data, the cross-sectional dispersion of forecasts is commonly used as a proxy for uncertainty. This article proposes a test for the validity of this practice that is a modification of Amemiya's (1977) procedure for estimating heteroscedasticity functions. To deal with the common practical problem of overlapping forecasts, a moving average specification is employed. The technique is applied to the Livingston forecasts of several variables, and the results suggest a significant positive relationship between cross-forecaster dispersion (a measure of forecaster discord) and the variance of ex post prediction errors. 相似文献
