Innovating to improve public service is regarded as potentially obligatory, not merely laudable, part of good public management. However, the moral content of an obligation to innovate is not well understood. How can we innovate ethically? In academic bioethics and research ethics, the obligatory nature of the ‘research imperative’ is discussed and criticized. In this article, I outline the content of what I call the ‘innovation imperative’ and draw a parallel between the innovation imperative and the research imperative, arguing that the ethical principles that govern innovation in public service are similar to those governing research imperative in biomedical sciences.  相似文献

Providing nutrition information at the point of purchase is one approach that can be used to help consumers adopt and maintain a healthy diet. Previous research has examined consumer self‐reported notice and use of the information as well as how the design of the information affects its attention and use in a laboratory environment using eye‐tracking methodology. This study advances the literature by applying eye‐tracking methodology to explore consumer visual and choice behavior in a real shopping environment, and by recognizing that nutrition information competes with other visual stimuli in the store and consumers are vulnerable to a “limited attention span” for nutrition information in a shopping setting. Data came from a cross‐sectional survey conducted in two grocery stores in the United States in July 2014 with a convenience sample of 60 grocery shoppers while they were selecting and buying items from one of three product categories (ready‐to‐eat cereal, snacks, and soup). The study finds that point‐of‐purchase nutrition information faced strong competition for participants’ attention from other visual elements in a real shopping environment and the attention is dominated by nonnutrition elements, particularly brand/product name, product imagery, and product pricing. Nutrition‐related information, on the other hand, received much less attention, with claims and front‐of‐package nutrition symbols seen by more participants than the Nutrition Facts label. The study suggests that to more effectively enable nutrition information to “catch the eyes” of shoppers at the point of purchase, increasing consumer exposure to the information and enhancing shopper education may merit further investigation.  相似文献

Using Conjoint Analysis to Help Design Product Platforms   总被引:6,自引:0,他引:6  
This article illustrates how one can combine different conjoint analysis studies, each containing a core of common attributes, to help design product platforms that serve as the foundation for multiple derivative products. The illustration is based on actual, but disguised, data from a small company that makes electronic test equipment.
This article demonstrates that decisions that consider products individually are likely to be suboptimal and can be significantly different than those based on product platforms. Suboptimality can occur either when preferences for product features differ across markets or when a technology is more important to the overall company than it is to an individual product. Additionally, we show the importance of considering both fixed and variable costs when performing this type of analysis as sales, contribution, and profit-maximizing products are quite different. Finally, sensitivity analyses show that these results are robust with respect to assumptions about price sensitivity, fixed costs, and timing of entry. © 1999 Elsevier Science Inc.  相似文献

From systemically dispossessing Indigenous people of their territory for Euro-American settlement to routinely denying African American farmers operating loans in the 20th century, the US government's complicity in creating racial hierarchies in terms of land access is well documented. Less understood is how land policies oriented towards racial equity, namely, the Justice for Black Farmers Act (JBFA), and other initiatives that deal with land access as well as addressing racism more broadly, emerged during recent decades. In this article, we argue that such initiatives resulted from Black-led organizations and other farmer advocacy allies responding to neoliberal policy reforms. Concretely, even as these reforms destabilized farm economies, they also led to a decentralization of agricultural policy administration, which, in turn, created opportunities for community-based organizations to influence land governance. We make this argument after presenting a three-part periodization of the evolution of US land policy, starting with the emergence of racial hierarchies, then the period of partial reforms that began during the New Deal and, finally, the era of neoliberal reform.  相似文献

When and why did Sterling Area countries stop holding sterling as the majority of their foreign exchange reserves? This paper takes a comparative approach to examine the relative importance of various determinants of adherence to sterling in its declining years as an international currency. Using an original cross-national panel dataset covering the period 1965–79, we conduct survival analysis which systematically evaluates a comprehensive set of economic and political factors, at the country level as well as in international relations, about when and why countries chose to diversify their reserves away from sterling. Our results highlight the significance of international transactional factors in influencing adherence to sterling, while the effects of British geopolitical retrenchment, Commonwealth cultural ties, and distributional issues were more ambiguous and sensitive to local conditions. We also find that domestic political and historical factors, such as democracy and imperial legacy, played a role in sterling's international unravelling. Finally, we use our results to examine the experience of individual sterling countries and their decisions to diversify.  相似文献

Smallholder agriculture in sub-Saharan Africa is commonly characterised by high levels of technical inefficiency. However, much of this characterisation relies on self-reported input and production data, which are prone to systematic measurement error. We show theoretically that non-classical measurement error introduces multiple identification challenges and sources of bias in estimating smallholders' technical inefficiency. We then empirically examine the implications of measurement error for the estimation of technical inefficiency using smallholder farm survey data from Ethiopia, Malawi, Nigeria and Tanzania. We find that measurement error in agricultural input and production data leads to a substantial upward bias in technical inefficiency estimates (by up to 85% for some farmers). Our results suggest that existing estimates of technical efficiency in sub-Saharan Africa may be severe underestimates of smallholders' actual efficiency and what is commonly attributed to farmer inefficiency may be an artefact of mismeasurement in agricultural data. Our results raise questions about the received wisdom on African smallholders' production efficiency and prior estimates of the productivity of agricultural inputs. Improving the measurement of agricultural data can improve our understanding of smallholders' production efficiencies and improve the targeting of productivity-enhancing technologies.  相似文献
