Our purpose in this paper is to consider a procedural objection to the death penalty. According to this objection, even if the death penalty is deemed, substantively speaking, a morally acceptable punishment for at least some murderers, since only a small proportion of those guilty of aggravated murder are sentenced to death and executed, while the majority of murderers escape capital punishment as a result of arbitrariness and discrimination, capital punishment should be abolished. Our targets in this paper are two recent attempts, by Thomas Hurka and Michael Cholbi respectively, to defend the view that ‘levelling down’ (that is, reducing the punishment imposed on a criminal from the punishment he absolutely deserves to a less severe punishment in order to achieve proportionality relative to the criminals who have escaped the punishment they absolutely deserve) is, in the context of capital punishment, morally permissible. We argue that both Hurka and Cholbi fail to show why the arbitrariness and discrimination objection impugns the death penalty.

The relationship between family functioning and adolescents’ physical aggression has been well established, but whether these relationships might differ by ethnicity has received less attention. Ethnic variations may be important for targeting prevention programs to specific youth and families. This study examined the longitudinal relationship between family cohesion, parental monitoring, and physical aggression using data from the Multisite Violence Prevention Project sample of high-risk youth (elevated aggression). Participants were 1,232 high-risk middle school students (65 % male; 70 % African American; 15 % Hispanic). Meaningful demographic variations were identified. After controlling for intervention condition and study site, family cohesion was significantly negatively related to physical aggression, more so for Hispanic youth. Parental monitoring was negatively associated with physical aggression for African American youth only. Our findings point to the importance of developing culturally sensitive family interventions to prevent physical aggression in middle school.  相似文献

Flexible allocation of crops among food and non-food uses is a key driver of global agri-food system change. Focusing on United States corn production, I explore the dynamics of flex crops, scrutinizing agri-industrial relationships and the distribution of agri-food system value and control. I situate crop flexing as exchanging use value, as opposed to converting use into exchange value without altering the commodity's use. Asking ‘Flexible for whom?' in the context of agri-food system crises, I find: (1) flex crops exacerbate contradictory food security and over supply crises, and that the distribution of flexibility and benefit in the agri-food system they provide depends on the organization of labor; (2) crises of accumulation tie flex crops to agri-food system financialization, which subordinates use to exchange value, obfuscating their relationship and distancing agricultural products and uses from their basis in nature and labor; and (3) debates over US corn flexing illustrate the utility of focusing on power and politics in crop flexing decisions and demonstrate US corn flexing to be a fix for climate and accumulation crises. Findings suggest that examining the distribution of value and control and the positions of labor and nature in the agri-food system may be productive for global flex crop research and advocacy in the future.  相似文献

The International Fund for Ireland and the European Union (EU) Peace III Fund have provided external economic resources to local community projects in Northern Ireland and the Border region to support intercommunal relations, community development, economic development, peacebuilding and reconciliation. The British and Irish governments, the EU, and the USA see the economic aid as their commitment to support the peace process, nurture the local voluntary sector, and build the peace dividend. The research findings demonstrate that the reality on the ground is more complex. Some believe that the economic assistance has created employment opportunities, built capacity, and localized peacebuilding knowledge. Others are more sceptical and perceive that the aid has created dependency, facilitated a competitive milieu, and has not transformed relationships in a sectarian environment.  相似文献

Abstract

Agricultural interventions are thought to have the potential to improve nutrition, but little rigorous evidence is available about programmes that link the two. In this article, we study impacts of an integrated agricultural and nutritional biofortification project, the REU in Mozambique. We first provide evidence on dietary impacts of the programme and then examine impacts of the programme by participation intensity. Using OLS and IV techniques, we find that more intense participation in both project components led to larger impacts. The results therefore have important implications for refining the design of future projects attempting to link agricultural and nutrition interventions.  相似文献

ABSTRACT

Outcome based policies promote the use performance accountability models. However, the impact these policies have on the ethical culture of public sector organizations has not been adequately assessed. This research examines performance accountability reforms by examining the City of Atlanta’s implementation of federal and state performance policies. The analysis reveals the use of performance models in vulnerable organizations negatively impact employees’ ethical behavior. Teachers and administrators altered test results, delivered threats, misled parents and students about performance outcomes, and were dishonest with state investigators to give the illusion that performance goals had been met or exceeded.  相似文献

The role of the courts is quite important, especially in the protection of individual rights and liberties. Many counter-terrorism policies implemented at the national level often infringe on these rights, and courts are the best line of defense against these violations of liberty. However, courts do not always rule in favor of liberty, sometimes ruling in favor of a strict government policy. This analysis seeks to explain the conditions that may lead courts to rule in favor of, or against, the government, arguing that political fragmentation is a potentially key factor in determining when particular case outcomes occur.  相似文献

The visual stylistic elements of graffiti are increasingly being used in the commercial world of advertising and marketing, as backdrops for music videos, and in merchandise and packaging. This market-oriented graffiti constitutes the mainstreaming of a subculture, that is, selling the stylistic subcultural elements as a new fad. Subsequently, commercial graffiti has been criticised for undermining the essence of real graffiti as the very aspect it seeks to oppose is now served, and in the process graffiti is robbed of its resistance identity. This article engages critically with this view by enquiring how Johannesburg commercial graffiti writers make sense of their commercial graffiti work. In a qualitative study, 11 commercial graffiti writers, who are engaged in small commercial contracts or who are freelancing for well-established consumer brands, and full-time graphic designers, were interviewed. Reoccurring themes that arose included self-expression and simplifying graffiti styles to be more accessible and “pretty” for general public consumption. Albeit in a different way, the recognition the graffiti writers gained from the public through their commercial work echoes some elements of the recognition gained through graffiti crews. Probably the most astounding finding of the study is that they felt that the commerciality of graffiti is simply a temporary phase that will eventually fade.  相似文献

A growing body of literature explores the process of coproduction by citizens and government employees in providing goods and services, yet research that attempts to link coproduction to organizational performance offers contradictory findings. It is possible that these conflicting results are a consequence of trying to compare distinct categories of coproduction. This study identifies types of coproduction, classified by which organizational tasks citizens can influence during stages of policy design and implementation, and tests whether these types have different effects on student proficiency in Mathematics and English Language Arts using data from New York City schools between 2007 and 2009. This study then tests the degree to which different types of coproduction moderate the negative effect of environmental turbulence on performance. Results confirm that types of coproduction have varying effects on organizational performance and can reduce, and even eliminate, the negative effect of a turbulent environment on student outcomes.  相似文献
