This paper reviews estimates of food related greenhouse gas (GHG) emissions at the global, regional and national levels, highlighting both GHG-intensive stages in the food chain, and GHG-intensive food types. It examines approaches that have been proposed for mitigating emissions at each stage in the chain and looks at how these sit within wider discussions of sustainability. It finds that efficiency-focused technological measures, while important, may not only be insufficient in reducing GHGs to the level required but may also give rise to other environmental and ethical concerns. It gives evidence showing that in addition to technological mitigation it will also be necessary to shift patterns of consumption, and in particular away from diets rich in GHG-intensive meat and dairy foods. This will be necessary not just in the developed but also, in the longer term, in the developing world. This move, while potentially beneficial for food secure, wealthier populations, raises potentially serious nutritional questions for the world’s poorest. A priority for decision makers is to develop policies that explicitly seek to integrate agricultural, environmental and nutritional objectives.  相似文献

Estimating the impact of rural investments in Nepal   总被引:1,自引:0,他引:1  
As a largely rural society, most people in Nepal still depend upon agriculture as their major livelihood strategy. Therefore, it is important to improve the allocation efficiency of limited public expenditures to promote agricultural growth and poverty reduction. However, evaluating the returns of public investment is limited by methodological challenges. We use hedonic and panel data methods to examine the returns to different types of rural public investments including roads, irrigation and extension advice. The use of diverse identification strategies reduces the risk of using a narrower set of results driven primarily by a particular methodology. We find that rural roads and irrigation are one of the most productive public expenditures according to the benefit-cost ratio calculations, though the magnitudes of these ratios depend on methodology.  相似文献

This article examines a case study of the implementation of a performance management system in public sector housing in Fiji. The aim is to explore and provide interpretations of why performance management and measures were introduced and implemented and reveal if the indicators were appropriate to serve the strategies of the organisation. The article draws on diffusion of innovation theory and explores the effectiveness of performance management. The research approach is qualitative in nature and uses a case study strategy. Interviews and documentary evidence provide the empirical basis for the research. The organisation has established formal objectives at both institutional and departmental levels and has a performance management system at both levels. With growing pressure for commercialisation from donor agencies, the accounting and managerial practices seem to contradict the organisation's original purpose to provide housing needs for the poor. The case study extends the literature on performance management in developing countries and illuminates the deficiencies within the performance management system. This study has implications for practitioners and researchers as it promotes a better understanding of a new public management practice technique which, in this case, was inadequate to satisfy local housing needs.  相似文献

This study investigates whether gold, USD, and Bitcoin are hedge and safe haven assets against stock and if they are useful in diversifying downside risk for international stock markets. We propose a combined GO-GARCH-EVT-copula approach to examine the hedge and safe haven properties of gold, USD, and Bitcoin. We then examine the attractiveness of these assets in reducing stock portfolio risk by using downside risk measures estimated by the proposed approach and other competing models. We also evaluate the relative performance of the proposed model in reducing downside risk with the competing models. The findings of the study indicate that the USD is the most valuable hedge and safe haven asset closely followed by gold, while Bitcoin is the least valuable. It is also observed that the proposed combined approach performs best in reducing the portfolio downside risk. The findings of this study are of significance for portfolio managers and individual investors who wish to protect the portfolio value during market turmoil.  相似文献

Build-to-order (BTO) and lean manufacturing processes are changing the paradigms under which businesses-to-business marketers operate. For example, BTO processes allow marketers to customize products to a greater degree, creating a competitive advantage over traditional manufacturing. Business-to-business (B2B) marketers who take advantage of the operational efficiencies and effectiveness that emerge from BTO are outperforming firms that utilize traditional manufacturing processes in multiple industries, such as office furniture, personal computers, and windows. This paper examines the long-term impact of the adoption of build-to-order manufacturing strategies on the marketing function and identifies marketing strategies associated with successful BTO companies. Throughout, the paper highlights managerial implications and proposes directions for future research.  相似文献

A decision analytic approach for evaluating new aviation safety products and technologies is developed and demonstrated to consolidate five existing program assessment metrics to develop a unified metric that simultaneously considers the relative importance and contribution of each. This allows for a meaningful and objective evaluation and comparison of the National Aeronautics and Space Administration (NASA) Aviation Safety Program (AvSP) advanced aeronautical products and technologies. The resulting decision model is referred to as the Composite Program Assessment Score (CPAS). The CPAS includes the five existing metrics; technical development risk, implementation risk, fatal accident rate reduction, safety benefits and cost, and safety risk reduction, which are each defined and quantified by different sources. The CPAS involves the scaling and combination of these individual metrics. In this paper, two alternative combinatorial modeling approaches to calculate the CPAS are presented. The weighted sum model and an additive value theory model are compared and contrasted. The resulting CPAS metrics allow an overall comparison of all 48 of the NASA AvSP products and technologies. Currently CPAS is based on preliminary weight measures from subject matter experts to reflect the relative importance of each metric. Actual case studies of both linear and non‐linear value functions are demonstrated.  相似文献

University campuses across Canada and elsewhere are developing and implementing emergency alert systems to warn campus community members about a variety of threats. In this study, focus group discussions were used to examine how undergraduate students living on campus may respond to an emergency alert. A focus group activity used tornado, fire and threatening message alert messages to provide a context for the focus group discussions. After reading the warning message, most students understood the warning message but there was uncertainty about the non-specified threat and how and where to evacuate. Many would believe a message sent by the university as long as it was sent via a phone number that they associated with the university. Personalization of risk varied, and students reported that they would confirm a warning message with a variety of sources including student colleagues, faculty and teaching staff, television and internet sources. Taking protective action by sheltering in place was deemed to be feasible, however evacuation off campus was found to be problematic. We found that the nature of short message service text messages, the characteristics of universities, and the students’ home being in an on-campus residence influenced how the students may respond to an emergency alert message.  相似文献

The present paper examines the issue of whether interpersonal relationships are critical for global marketing of industrial products. The fields of relationship marketing, IMP group research, sales research, and network theory have stressed the importance of interpersonal relationships in the business-to-business or industrial marketing context. In contrast to this emphasis on interpersonal relationships, we argue that industrial firms can both conceive and enhance marketing strategies based on developing high quality and consistent processes, products, services or outcomes (consistent processes and outcomes). Such strategies are especially important given the fact that developing interpersonal relationships is expensive due to their reliance on frequent and/or face-to-face communications. In this paper, we examine industry and country contexts that lead to the choice of alternative industrial product marketing strategies and highlight some future research directions and managerial implications.  相似文献

This paper presents a profile of poverty in Egypt for 1997. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic groups, provides information on the characteristics of the poor, illustrates the heterogeneity amongst the poor, and helps identify empirical correlates of poverty. This poverty profile is constructed using data from the Egypt Integrated Household Survey (EIHS), which is a nationwide, multiple‐topic household survey. One of the more striking set of findings relates to the differences between the poor and the non‐poor in their educational attainments. Our results indicate a significant literacy and schooling gap between the poor and the non‐poor. On average the poor have 2.6 fewer years of schooling than the non‐poor, and their literacy rate is 27 percent lower than the non‐poor. Our results also indicate that augmenting educational attainment of the poor does not require building more schools, but reducing the poor’s opportunity cost of attending schools and increasing their returns from extra schooling, both suggesting the importance of income generating activities as a policy instrument.  相似文献
