While Benefit-of-the-Doubt (BoD) models, as used in the context of composite indicator construction, seek to aggregate outputs only, they are formally equivalent to an input-oriented Data Envelopment Analysis (DEA) model in multiplier form. Strictly read, this introduces conceptually ambiguous results, as input adjustments have no real significance in the context at hand. At heart of this ambiguity lies a double interpretation of what is essentially a binding constraint in BoD’s underlying linear-fractional program. Moreover, there is a direct, reciprocal relation between the BoD-model and an earlier output-oriented DEA model introduced by Lovell et al. (Eur J Oper Res 87:507–518, 1995) for similar purposes. Although these models are essentially similar, I also show that there are instances (i.e. when adding additional weight restrictions) in which the results of one alternative are easier to communicate. The models surveyed in this paper are complemented with a short application on human development data for females living in Brussels municipalities.  相似文献

One potential consequence of rising top‐income concentration is borrowing by less‐affluent households attempting to maintain relative living standards. This paper evaluates the “keeping up with the Joneses” phenomenon, examining the responsiveness of payment‐to‐income ratios for different debt types across the income distribution to changes in income among affluent households. The analysis provides evidence for the responsiveness of debt to rising top incomes. Middle‐ and upper‐middle‐income households take on more housing‐related debt and have higher payments in places with higher top‐income levels. Among lower‐income households non‐mortgage borrowing and debt payments decline, consistent with restrictions in the supply of credit. (JEL D63, D14)  相似文献

The sleep system (i.e. the combination of mattress and bed base) is an important factor of the sleep environment since it allows physical recuperation during sleep by providing proper body support. However, various factors influence the interaction between the human body and the sleep system. Contributing factors include body dimensions, distribution of body weight and stiffness of the sleep system across the mattress surface. During the past decade, the rise of several new bedding technologies has made it increasingly difficult for the consumer to select a proper sleep system. Therefore, this study presents a method to model human-bed interaction in order to objectively predict the ideal sleep system for a particular individual. The proposed method combines a personalized anthropometric model with standardized load-deflection characteristics of mattress and bed base. Results for lateral sleep positions show a root mean square deviation of 11.9 ± 6.1 mm between modeled spine shapes and validation shapes, derived from 3D surface scans of the back surface. The method showed to be a reliable tool to individually identify the sleep system providing superior support from a variety of possible mattress-bed base combinations.  相似文献

Multivariate genetic studies have revealed genetic correlations between antisocial behavior (ASB) and substance use (SU). However, ASB is heterogeneous, and it remains unclear whether all forms are similarly related to SU. The present study examines links between cannabis use, alcohol consumption, and aggressive and delinquent forms of ASB using a behavioral genetic approach. Participants were 1,688 adolescents (482 monozygotic twins, 852 dizygotic twins, and 354 nontwin siblings) aged 15–23 years old (M = 16.91), sampled from the community in the U.K. Multivariate model fitting revealed that the genetic components of alcohol consumption and cannabis use correlated with those of both aggression (.21 and .49, respectively) and delinquency (.35 and .69, respectively). Results suggest that both aggression and delinquency have genetic effects in common with alcohol consumption and cannabis use.  相似文献

This paper seeks to explain the survival of the Treatment Action Campaign (TAC) and to identify lessons it may offer on how social movements may resist demobilisation. It considers the role the TAC plays in the creation of social accountability dynamics around primary health care but with broader implications for strengthening rights-based notions of citizenship. The paper examines the TAC’s relative success in democratising public health care provision and explores shifts in the relationship between this social movement organisation and the South African state.  相似文献

ABSTRACT

This article responds to calls for more comparative historical studies in public relations history across nations and cultures with a comparative analysis of the propaganda operations of Islamic State with the Nazi Party. This comparative historical approach aims to reduce the uncertainty associated with extremist terrorism and bring a historic-communicative perspective to an organization that politicians and commentators arguably overestimate in what has been described as the “epistemological crisis” of Western counterterrorism. This investigation attempts a methodological expansion of public relations historiography by applying the theoretical approach of historical institutionalism as basis for comparison between the two institutions alongside conventional content and artefact analysis. The project identifies ten parallels in propaganda and concludes that some of these commonalities – including a focus on engaging and recruiting young people, for example – can provide historically-derived guidance on counter terrorism responses in the communicative sphere.  相似文献

There are two types of work typically performed in services which differ in the degree of control management has over when the work must be done. Serving customers, an activity that can occur only when customers are in the system is, by its nature, uncontrollable work. In contrast, the execution of controllable work does not require the presence of customers, and is work over which management has some degree of temporal control. This paper presents two integer programming models for optimally scheduling controllable work simultaneously with shifts. One model explicitly defines variables for the times at which controllable work may be started, while the other uses implicit modeling to reduce the number of variables. In an initial experiment of 864 test problems, the latter model yielded optimal solutions in approximately 81 percent of the time required by the former model. To evaluate the impact on customer service of having front-line employees perform controllable work, a second experiment was conducted simulating 5, 832 service delivery systems. The results show that controllable work offers a useful means of improving labor utilization. Perhaps more important, it was found that having front-line employees perform controllable work did not degrade the desired level of customer service.  相似文献

The United States is the world leader in confining bodies behind bars. As scholars, practitioners, and activists struggle against the problem of mass incarceration, this article makes a distinction between two competing perspectives, both of which seek to change the current criminal legal system: “prison abolition” and “reformism.” Each represents ideological and political differences in how mass incarceration should and could be resolved. Prior research has relied on historical methods and data to examine theoretical departures between prison reform and prison abolition, yet to our knowledge, there have been no explorations of these perspectives on new media. This article fills the gap, drawing on a sample of 2,112,206 tweets between 2011 and 2020 and engaging in an in-depth qualitative analysis of nearly 5,000 tweets over a 6-year period in order to investigate the ways Twitter users disclose and define their positions on criminal justice reform on one hand, and prison abolition on the other, and how these discussions have changed over time.  相似文献

New Zealand decriminalized sex work in 2004 with the passage of the Prostitution Reform Act (2003), which sets an explicit intention to prevent exploitation of sex workers and improve their welfare. This has demonstrably improved conditions for sex workers and provides a necessary context for addressing exploitation. However, little research has looked at how this works for brothel-based sex workers in New Zealand. This paper responds to that gap by examining how brothel operators in New Zealand exercise power and control and how sex workers experience that. The study draws on in-depth interviews conducted across New Zealand with 33 participants. These include staff from the New Zealand Sex Workers' Collective (2), brothel-based sex workers (18), operators (8), and sex worker/operators (5). We use a Foucauldian framework and Foucauldian Discourse Analysis to examine how disciplinary power informs brothel management, prompting the production of normative discourses of work that destabilize sex workers' safety at work. We conclude that decriminalization nevertheless provides an essential framework by which sex workers are able to resist disciplinary control (W/C 171).  相似文献
