The durability of central city districts in large metropolitan systems of the majority world has largely been attained through intricate intersections of physical, infrastructural, human and discursive materials, as these intersections are continuously remade through shifting constellations of the incremental initiatives of residents. Residents have learned to use the city as a place to continuously explore new relationships among things and extract a wide range of unanticipated capacities from them. This is a collective resourcefulness from which there might be much to draw in terms of using the carbon‐driven exigencies of infrastructural transformation as the occasion to reanimate more egalitarian political projects. Although many collective efforts are increasingly being disassembled, the reflections of a single resident of one of Jakarta's most heterogeneous residential districts points to how the revitalization of such efforts might be conceived. The efficacy of political efforts to address intensified vulnerability partly entails replenishing intense mixtures of built and physical environments as provocations and platforms for complex social maneuvers.  相似文献

The aim of the article is to investigate the role of stakeholder engagement and participation in nonprofit organizations’ sustainability reporting, according to the literature on third sector and stakeholder theory. To verify the levels of involvement, the authors conducted an empirical survey, using content analysis, on a sample of 54 sustainability reports of nonprofit organizations included in the Global Reporting Initiative database as of September 1, 2012. In order to strengthen the results obtained from the content analysis, the authors shared their findings with the organizations of the sample. The survey showed that there were some criticisms regarding stakeholder participation in the targeted research field. These are considered in the conclusions. Questions for the future included whether stakeholder engagement is moving from being simply a way to consult and influence stakeholders to being an effective instrument for involving them in nonprofit organizations’ reporting and decision-making processes, through mutual commitment.  相似文献

High-speed access to the Internet enhances economic prosperity, social development and global competitiveness. Significant progress has been made in broadband deployment in the last decade. Nevertheless, there are increasing gaps in broadband adoption, use and speed between, as well as within, the states. Federal and state legislators and regulators currently use a number of indicators such as adoption, availability and speed to track states’ progress in broadband diffusion in order to design appropriate policy responses. Single indicators, however, when analyzed individually, fall short of capturing multi-dimensional aspects of broadband diffusion and, thus, do not provide an integrated and easily comprehensible picture of states’ advancement. To monitor states’ overall progress it is useful to aggregate various indicators into a composite index that could measure the overall extent of broadband diffusion. A composite index can also provide with an important benchmark for designing policies to improve states’ overall performance. This paper offers a flexible framework for benchmarking states’ achievement in broadband diffusion by proposing a composite Broadband Achievement Index (BAI). The index combines several key performance indicators: broadband availability, adoption, competition, speed and the dispersion of broadband adoption within the states utilizing FCC's Form 477 data and the recently collected census block level broadband availability data from NTIA. The purpose is to provide a more comprehensive picture of where the states stand in their evolution toward high-performance America by measuring each state's current broadband achievement relative to other states and providing an important benchmark for assessing state-specific needs. The indicators are combined using the Benefit of the Doubt (BOD) methodology (Cherchye, Moesen, & Van Puyenbroeck, 2004). The methodology is founded on the premise that, absent a consensus on social policy priorities, that are, on which indicators are more important and should be given higher weights in the index, each state is granted leeway for deciding how to weigh its own indicators and the most favorable weights for indicators are determined for each state. A good relative performance in a particular dimension is seen as revealed evidence of setting high state policy priority to that indicator, when each state's specific policy priorities are unknown. Additionally, the Second Order Stochastic Dominance (SOSD) methodology is used to compare the dispersion of adoption in the states. Using SOSD the states are ranked under the assumption that proportionally higher and more equally distributed adoption rates are better.  相似文献

For an exchange economy with finitely many agents and a commodity space which is infinite dimensional, it is proved that competitive equilibria are the same as allocations belonging to the fuzzy core of the economy. The latter is further characterized as a subset of the ordinary core of a suitably associated continuum economy.
Riassunto Per un'economia di puro scambio con un numero finito di agenti e uno spazio dei beni di dimensione non necessariamente finita, si prova che gli equilibri Walrasiani possono essere caratterizzati come allocazioni che appartengono al nucleo fuzzy dell'economia. Inoltre, queste ultime allocazioni sono in corrispondenza biunivoca con allocazioni di tipo semplice che si trovano nel nucleo ordinario di un'opportuna economia che ha [0,1] come spazio rappresentativo dello spazio degli agenti.

The present study investigates the stock characteristic preferences of institutional Australian equity managers. In aggregate we find that active managers exhibit preferences for stocks exhibiting high‐price variance, large market capitalization, low transaction costs, value‐oriented characteristics, greater levels of analyst coverage and lower variability in analyst earnings forecasts. We observe stronger preferences for higher volatility, value stocks and wider analyst coverage among smaller stocks. We also find that smaller investment managers prefer securities with higher market capitalization and analyst coverage (including low variation in the forecasts of these analysts). We also document that industry effects play an important role in portfolio construction.  相似文献
