The 2009 American Cash for Clunkers program, which subsidized consumers who scrapped old vehicles and purchased new vehicles, was promoted by appealing to multiple constituencies. We evaluate the policy and alternatives according to its stated goals: emissions reductions, economic stimulus, and reducing inequality. We calibrate a dynamic partial equilibrium portfolio model to match consumer expenditure data from 1998 to 2011 focusing on heterogeneity across cars and trucks. We find the program generated $0.17 in environmental benefits, $0.28 in consumer surplus, and $0.31 in net discounted additional spending per subsidy dollar. Since subsidies largely went to middle-income infra-marginal consumers, the program exacerbated consumption inequality. We evaluate alternative policy designs and find no policy which simultaneously improves all outcomes. (JEL H23, L52, L92, D63) 相似文献

ABSTRACT This paper is about the changing imaginations of social work in an increasingly entangled world. It is also about the ways in which literatures shared across time and space encourage us to identify with larger collectivities. My central argument is that if social work is to find a larger vision in the wake of the failure of a range of modern progress narratives, we must engage differently with the challenge posed by multiplying and sometimes conflicting knowledge communities. Thinking with contemporary debates in transdisciplinary critical social theory, I nominate and explore a number of alternative heuristics—‘generational problematic,’ ‘translational space,’ and ‘imagined communities’—in support of future work on the uneven temporal and spatial communities of affiliation that reproduce and change what social work is, or could be, about. I conclude with theoretical suggestions, and some thoughts toward how social work education might better support incoming generations to locate themselves within the broader life-course of the discipline and profession. 相似文献

This paper provides a set of principles and ethics, developed in collaboration between Pacific‐ and Australian‐based researchers, to guide research practice in a project enabling the self‐reporting of children with disability in Vanuatu and Papua New Guinea (PNG). The paper presents both a summary of academic literature relating to these principles and ethics, as well as their succinct ‘translation’ into a set of action statements for researchers working with children with disability. The paper offers a base for further development by others to guide research practice and foster the autonomous participation of children with disability in developing countries. 相似文献

In 1413 at the death of his wife Guillemot, Jean Aubert, a group of witnesses and a clerk of the local mayoralty met to value the possessions of their residence, resulting in an inventory full of notes and values on rooms and their objects. Within the existing historiography of the Burgundian Netherlands and its northern European neighbours, inventories and their objects tend to be analysed from two perspectives: the Burgundian court and the ‘consumer revolution’. Applying insights from Erving Goffman and Bruno Latour, this article suggests a third perspective should have priority: the urban ‘theatre’ within which objects were documented and placed. Therefore it sets up an alternate methodology which begins with the inventory to build a picture of the theatre (the urban context and residence), the actors (the Aubert family) and the audience (the witnesses of the inventory) to establish new insights into the operation of Burgundian power and the dynamics of the ‘consumer revolution’. 相似文献

This study evaluates and synthesizes qualitative evidence addressing factors affecting a child’s decision to disclose an experience of sexual abuse. Childhood sexual abuse is a devastating crime, with long-term negative impacts. Understanding the factors that affect a child’s decision to disclose is vital. Disclosure enables access to support and protection, both therapeutically and legally. A systematic review was conducted focusing on factors affecting a child’s decision to disclose an experience of sexual abuse. Seven studies were identified, quality appraisal undertaken, and meta-ethnography used to synthesize the studies. Six new super-ordinate themes were developed: Fear of what will happen; Others’ reactions: fear of disbelief; Emotions and impact of the abuse; An opportunity to tell; Concern for self and others; and Feelings toward the abuser. Themes indicated the importance of support, structure, and opportunity to facilitate disclosure and should be utilized by agencies to develop practices that facilitate disclosures. 相似文献

Colombian laypersons’ perspectives regarding actual and potential drug policies were examined. Adults (N = 395) aged 18–68 and living in Bogota were presented with 24 vignettes that were composed according to two within-subject orthogonal factor designs: (a) Demand for drugs in the country × Current government policy regarding soft and hard drugs (from “laissez faire” policy for all drugs to complete prohibition of all drugs) and (b) Information campaigns regarding the dangerousness of drugs × Current policy. Participants rated the level of acceptability of each policy. Seven different perspectives were identified that can be grouped into five broad views. The first one (50 % of participants) was called “radical constructionists” because participants considered that all policies were unacceptable. The second one (19 %) was called “cultural conservatives” because only one drug policy was considered fully acceptable: complete prohibition (although half of the members of this group were willing to allow soft drugs to be sold freely). The third one (14 %) was called “progressive prohibitionists” because the preferred policies in this group were either complete prohibition or complete regulation by the government. The fourth one (8 %) was called “free trade libertarians” because the dominant opinion was that the drug market should be free. The last one (5 %) was called “progressive advocates of legalization” because the preferred policy in this group was complete regulation of all substances. In most cases, the presence of information campaigns was highly valued. Methodological implications and implications for decision-makers are discussed. 相似文献

The ‘big story/small story’ distinction has emerged as a discrete approach to narrative analysis. Proponents of this approach are critical of the ‘big stories’ elicited by structural analysts, which they see as highly structured narratives of past experiences, typically elicited in an interview context. In contrast, they highlight the importance of studying the fragmented, contextualised ‘small stories’ that arise in everyday conversation/interaction. We question the basis of this distinction and we suggest that it unnecessarily proliferates analytic categories. Further, we suggest that the methodologies followed by ‘small stories’ analysts are often similar to those used to elicit ‘big stories’ and are hence open to similar criticisms; in particular, a failure to fully consider the issue of (contextual) naturalism. Drawing on interviews of crime/terrorism in Northern Ireland, we show how these data comprise both ‘big stories’ and ‘small stories’ within the same context and often within the same narrative. 相似文献

A Bayesian multi-category kernel classification method is proposed. The algorithm performs the classification of the projections
of the data to the principal axes of the feature space. The advantage of this approach is that the regression coefficients
are identifiable and sparse, leading to large computational savings and improved classification performance. The degree of
sparsity is regulated in a novel framework based on Bayesian decision theory. The Gibbs sampler is implemented to find the
posterior distributions of the parameters, thus probability distributions of prediction can be obtained for new data points,
which gives a more complete picture of classification. The algorithm is aimed at high dimensional data sets where the dimension
of measurements exceeds the number of observations. The applications considered in this paper are microarray, image processing
and near-infrared spectroscopy data. 相似文献

Education is one major public service in which quasi‐markets and other choice‐based mechanisms are now established methods of delivery. The types of school people choose, and the extent to which their choices are realized, have a fundamental impact on the outcomes of any mechanism of school choice. In this article, we provide a comparative analysis of the school choice strategies of middle‐class families in London and Paris. We draw on approximately 200 in‐depth interviews carried out across the two cities. This enables us to investigate the extent to which middle‐class school choice strategies transcend the institutional context provided by both the local (state and private) schools market and national education policy in England and France. We discuss these findings in the context of current school choice policy and consider their implications for future policy design. 相似文献
