Disaster relief presents many unique logistics challenges, with problems including damaged transportation infrastructure, limited communication, and coordination of multiple agents. Central to disaster relief logistics is the distribution of life-saving commodities to beneficiaries. Operations research models have potential to help relief agencies save lives and money, maintain standards of humanitarianism and fairness and maximize the use of limited resources amid post-disaster chaos. Through interviews with aid organizations, reviews of their publications, and a literature review of operations research models in transportation of relief goods, this paper provides an analysis of the use of such models from the perspective of both practitioners and academics. With the complexity of disaster relief distribution and the relatively small number of journal articles written on it, this is an area with potential for helping relief organizations and for tremendous growth in operations research. 相似文献

Environmental and socio-economic sustainability of chinampas (raised beds) in Xochimilco,Mexico City
Yair Merlín-Uribe Carlos E. González-Esquivel Armando Contreras-Hernández Luis Zambrano Patricia Moreno-Casasola 《国际农业可持续发展杂志》2013,11(3):216-233
The chinampas (raised beds) of Xochimilco, Mexico City, are highly productive, traditional wetland agricultural systems, which were able to feed most of the population in pre-hispanic times. There is a strong trend to substitute chinampas with plastic greenhouses for flower production, which creates negative impacts in the landscape, environment and culture. This study compares the environmental and socio-economic sustainability of chinampas and greenhouses, at both the farm and regional levels, using the MESMIS framework. Even though the results show that greenhouses are more profitable, the contribution of chinampas to ecosystem services cannot be substituted by greenhouses, as tree cover is lost, canals are filled and food is not provided. Greenhouses had a higher diversity, but also a higher agrochemical use and are heavily dependent on external inputs and subsidies. Chinampas have shifted from staple crops to commercial horticulture in order to remain a technically viable and economically feasible option for local farmers. However, compensation mechanisms for the provision of ecosystem services are urgently needed if this ancient system is to be maintained. The framework allowed the integration of indicators at both farm and regional scales, combining on-farm surveys with GIS techniques, which could assist in ecosystem service valuation. 相似文献

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business
management, as it would provide an economic justification for the social investment insofar as it contributes to the creation
of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains
this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from
the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from
previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors
that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during
2004. 相似文献

The first wave, conducted in 2002–2003, of an in-depth panel survey in Quebec City, was used to compare the out-of-home activities of adults who had the use of mobile phones, or of internet at home, to those who did not. A unique feature of the survey was the inclusion of respondents’ perceptions of the both the temporal and the spatial flexibility of all executed activities. We find, after statistical controls for other factors, that mobile phone use was positively associated with activity and trip levels, while internet access was negatively associated. These two ICTs also had mostly opposite relationships with the routinisation and pre-arrangement of activities and with some conventionally defined sub-classes of activity. 相似文献

In order to maintain competitiveness, governments in developing economies seem to have pursued purchasing power parity (PPP) exchange rate rules, by adjusting the nominal devaluation rate in response to real exchange rate deviations from an intermediate target. This article shows that these rules are likely to induce macroeconomic instability, as they generate sunspot‐driven fluctuations that are in fact learnable by agents in the Expectational‐Stability sense. It finds that the existence of these “learnable sunspots” depends, among others, on open economy features, including the degree of openness and the degree of exchange rate pass‐through to consumer's import prices. 相似文献

We show how vicious circles in countries' credit histories arise in a model where output persistence is coupled with asymmetric information about output shocks. In such an environment, default signals the borrower's vulnerability to adverse shocks and creates a pessimistic growth outlook. This translates into higher interest spreads and debt servicing costs relative to income, raising the cost of future repayments, thereby creating “default traps”. We build a long and broad cross-country dataset to show the existence of a history-dependent “default premium” and of significant effects of output persistence on sovereign creditworthiness, consistent with the model's predictions. 相似文献

This paper analyzes the problem of designing mechanisms to implement efficient solutions in economies with externalities. We provide two simple mechanisms implementing the Pigouvian Social Choice Correspondence in environments in which coalitions can or cannot be formed. 相似文献
