Understanding demand in the new plug‐in hybrid electric vehicle (PHEV) market is critical to designing more effective adoption policies. We use stated preference data from an innovative choice experiment to estimate demand for PHEVs relative to battery electric vehicles (BEVs) and to explore heterogeneity in demand for these vehicles. We find the gap between willingness to pay for PHEVs and their price premium over conventional vehicles is on the order of current subsidies, while that of BEVs is an order of magnitude larger. We use a latent class model to show PHEVs draw a different consumer segment into the market. (JEL Q5, R41)  相似文献

This essay explores the relationship between teaching and activism by interrogating if teaching in higher education should be considered activism. Through a discussion of my commitment to data literacy and how participatory democracy, as practiced by Black Freedom Movement organizer Ella Baker, informs my pedagogy, I interrogate if activism and academic labor should be conflated. In the process I examine how my assessment is informed by my relationship to activism, the academy, my career trajectory, and racism as part of academic work conditions.  相似文献

Traditional food initiatives often aim to increase food access through market-based, needs-driven models, leaving basic food requirements unmet for many in the current U.S. food system. Employing qualitative community-based participatory methods, we examine the asset-based developmental stages of a local-level Food and Resource Center (FRC) in rural Stillwater, OK. We consider the ways that social capital can be activated as a community asset for development, articulating how social networks are used to identify, mobilize, and galvanize community support. How has the community identified and mobilized a “stock” of social capital to employ an asset-based approach to developing a food resource center? How can the FRC enhance social capital for the community as a whole? We provide insight into how individual, agency, and institutional actors act as pivotal resources for community development, delineating the ways in which community social capital and asset-based development can influence an organization's operational goals. Additionally, we explore strategies used to enhance linking and bonding forms of social capital as well as obstacles to bridging social capital in the broader community.  相似文献

Overweight and obesity are known risk factors for several modifiable, if not preventable diseases. Growing evidence suggests that lesbians may have higher rates of obesity than other women. This study was designed to describe weight loss and behavior changes related to food choices and exercise habits among lesbians who participated in a predominantly lesbian, mainstream, commercial weight loss program. Behavioral changes were recorded in exercise, quality of food choices, and number of times dining out. Although there were several limitations based on sample size and heterogeneity, the impact of a lesbian-supportive environment for behavior change was upheld.  相似文献

To date, the dominant approach to leadership research assumes that all aspects of the leadership role within a team are embodied by a single individual. In the real world, however, this is rarely the case. Rather, multiple individuals within the team may serve as leaders in both formal and informal capacities, and the shifting of leadership responsibilities is often rooted in which individual's expertise is most relevant to the given problem. In the present effort, we add to the rapidly growing body of work that focuses on the distribution of the leadership role among multiple individuals. We have reviewed relevant extant literature and proposed an integrated framework for understanding the collective leadership process. Also, in developing this framework we have taken an information and expertise-based approach such that we propose that collective leadership, or the distribution of the leadership role, is a function of selectively utilizing the information or specialized expertise that individuals within the network possess. In reviewing the framework, 55 propositions with regard to the collective leadership process are outlined and suggestions for future research are provided.  相似文献

This article proceeds from a photograph. It does so to begin an investigation of the diverse sites within and beyond it, and the reflections of several enactments of nation, culture, belonging and non-belonging. The image in question depicts a group of children waving flags. It is an old photograph, possibly removed from our ‘present’, though it holds within it multi-temporal spaces into which we might enter. The aim of this article is to do just that – to enter the image, armed with all the things a researcher gathers in terms of background data, narratives and contexts, and examine the complex negotiations enacted within and beyond it. How does this group of flag-waving children impact on us today? This article explores the extent to which an understanding of a temporal enactment of nation in displacement might reflect on contemporary negotiations of citizenship, culture and representation.  相似文献

This paper focuses on the role that inequality plays in shaping political support for child labour regulation policies. We provide a model of the evolution of child labour, fertility and human capital where the heterogeneity between low- and high-skilled workers allows for an endogenous analysis of inequality generated by child labour. Depending on the initial level of inequality, child labour regulation policies can affect the welfare of low- and high-skilled workers in different ways and therefore can have an impact on political support for their introduction. The possible conflicts of interest that may arise between the two groups can help explain the difficulties that many governments have when dealing with the issue of child labour.  相似文献

Datasets that are subjectively labeled by a number of experts are becoming more common in tasks such as biological text annotation where class definitions are necessarily somewhat subjective. Standard classification and regression models are not suited to multiple labels and typically a pre-processing step (normally assigning the majority class) is performed. We propose Bayesian models for classification and ordinal regression that naturally incorporate multiple expert opinions in defining predictive distributions. The models make use of Gaussian process priors, resulting in great flexibility and particular suitability to text based problems where the number of covariates can be far greater than the number of data instances. We show that using all labels rather than just the majority improves performance on a recent biological dataset.  相似文献
