Considerable policy and academic attention has been focused on the topic of food deserts. We consider this topic from an economic perspective. First, we consider how the components of a standard economic analysis apply to the study of food deserts. Second, using this economic lens, we revisit the empirical literature on food deserts to assess the progress that has been made regarding whether food deserts are problematic in the U.S. Overall, despite several studies documenting the existence of food deserts in local areas, shortcomings in available data have not allowed researchers to convincingly document the presence or absence of food deserts on a national scale, and virtually no research has provided insight as to why food deserts might exist. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

Cosmetic surgery is increasing in popularity in Australia and New Zealand, as it is across other Western countries. However, there is no systematic mechanism for gathering data about cosmetic surgery, nor about the outcomes of that surgery. This column argues that the business of cosmetic surgery in Australia has questionable marketing standards, is conducted with little scrutiny or accountability and offers patients imperfect knowledge about cosmetic procedures. It also argues that while medical practitioners debate among themselves over who should carry out cosmetic procedures, little attention has been paid to questionable advertising in the industry and even less to highlighting the real risks of undergoing cosmetic surgery. While consumers are led to believe that cosmetic surgery is accessible, affordable and safe, they are sheltered from the reality of invasive and risky surgery and from the ability to clearly discern that all cosmetic procedures carry risk. While doctors continue to undertake advertising and engage in a territorial war, they fail to address the really important issues in cosmetic surgery. These are: providing real evidence about what happens in the industry, developing stringent regulations under which the industry should operate and ensuring that all patients considering cosmetic surgery are fully informed as to the risks of that surgery. 相似文献

In this paper, we consider three issues raised by the apparentinconsistency between the current research practice of usingcounty-based markets (Metropolitan Statistical Areas (MSAs)and non-MSA counties) to investigate the validity of the theoreticalunderpinnings of bank merger policy and the current regulatorypractice of using Federal Reserve (FR) banking markets, whichoften do not follow county lines, to implement that policy.Using a national sample of bank and thrift branch deposit data,we find that county-based areas cannot simply substitute forFR markets in the implementation of bank merger policy. Forexample, numerous potential mergers would raise competitiveissues in county-based areas, but not in FR markets, and viceversa. We also conclude that, because of the relative difficultyof assembling demographic data for non-county-based areas, itis impractical to consistently use FR markets in bank mergerpolicy research. However, we do find that, despite the inconsistenciesbetween the two types of markets, analysis that uses county-basedareas is relevant for bank merger policy that is implementedwith FR markets. For example, we find that profitability regressionresults using variables based on FR markets are similar to thosefound using variables based on MSAs and non-MSA counties. 相似文献

In 1999, the Ontario provincial government introduced into its high school curriculum a requirement that students complete
40 h of volunteer community service before graduation. At the same time, the high school curriculum was shortened from five
years to four. Consequently, the 2003 graduating class of Ontario high school students contained two cohorts, the first of
the 4-year cohorts that was compelled to complete a mandated community service requirement, and the last of the 5-year cohorts
that was not. Using a quasi-experimental design, we surveyed 1768 first-year university students in terms of their perceptions
and attitudes about the nature and amount of previous volunteering, attitudes towards community service, current service involvement
and other measures of civic and political engagement. Comparisons of the two cohorts indicate that, while there were discernible
differences between the two cohorts in terms of their past record of community service, there were no differences in current
attitudes and civic engagement that might plausibly be attributed to participation in the mandatory service program. Results
are discussed with relation to the current debate concerning the impact of mandatory volunteering policies on intrinsic motivation
to volunteer.

Reviewing the literature on police-induced confessions, we identified suspect characteristics and interrogation tactics that influence confessions and their effects on juries. We concluded with a call for the mandatory electronic recording of interrogations and a consideration of other possible reforms. The preceding commentaries make important substantive points that can lead us forward—on the effects of videotaping of interrogations on case dispositions; on the study of non-custodial methods, such as the controversial Mr. Big technique; and on an analysis of why confessions, once withdrawn, elicit such intractable responses compared to statements given by child and adult victims. Toward these ends, we hope that this issue provides a platform for future research aimed at improving the diagnostic value of confession evidence. 相似文献

Mental health courts (MHCs) are rapidly expanding as a form of diversion from jails and prisons for persons with mental illness
charged with crimes. Although intended to be voluntary, little is known about this aspect of the courts. We examined perceptions
of voluntariness, and levels of knowingness and legal competence among 200 newly enrolled clients of MHCs at two courts. Although
most clients claimed to have chosen to enroll, at the same time, most claimed not to have been told the court was voluntary
or told of the requirements prior to entering. The majority knew the “basics” of the courts, but fewer knew more nuanced information.
A minority also were found to have impairments in legal competence. Implications are discussed. 相似文献

The following case study concerns the period in which Carlos Vielman, a well-heeled Guatemalan businessman from a prominent family, became the interior minister of the Óscar Berger administration. While minister, Vielman oversaw the creation of several special units that “acted as an organized crime group,” according to Guatemalan and international investigators. He, along with several of his police deputies were eventually charged for murder. He was later exonerated by a court in Spain, while others were prosecuted. This case study delves into that period, exploring how Vielman’s ministry represented an extension of the Guatemalan elite’s approach towards security and the government writ large to thwart rivals, regardless of the violent and criminal consequences. 相似文献

This study is part of a larger research project on police crime in the United States. Police crimes are those criminal offenses committed by sworn law enforcement officers who have the general powers of arrest. Profit-motivated police crime involves officers who use their authority of position to engage in crime for personal gain. This study reports the findings on 1,591 cases where a law enforcement officer was arrested for one or more profit-motivated crimes during the seven-year period 2005–2011. The profit-motivated arrest cases involved 1,396 individual officers employed by 782 state, local, special, constable, and tribal law enforcement agencies located in 531 counties and independent cities in 47 states and the District of Columbia. Our data is the first systematic study of profit-motivated police crime. The study describes the nature of this form of police misconduct in terms of several dimensions, including the characteristics of police who perpetrate these crimes, where it occurs, the specific criminal charges, and the contexts within which profit-motivated police crime is punished through police agencies and the criminal courts. 相似文献
