Environmental Protection Versus Economic Development: A False Trade‐Off?

Is a trade‐off between the social benefits of regulation and the economic benefits of development inevitable? We argue that environmental regulation may deter economic growth in some contexts, however, in other contexts the benefits of regulation may be obtained with little or no economic loss. We develop an explanation of the economic impacts of state environmental policy based on a model of public influence on private resource allocation decisions. In this model, we assume utility‐maximizing firms will make investment choices based upon the projected profits on their investments and their willingness to accept the risk associated with the investments. We assert that state policies and administrative institutions influence perceptions of risk by increasing or decreasing uncertainty over future environmental policy and influence return on investments at particular locations by affecting firm‐level production costs. Our results confirm that certain administrative arrangements for environmental regulation may enhance, rather than impede, economic development.     

Dangerous Revisionism: On the Founders, ‘Neocons’ and the Importance of History

Debates regarding the Bush Administration's grand strategy began long before the forty-third president left office. A group of distinguished historians and political scientists have argued over the course of the last few years that the Administration's grand strategy did not represent a major break with historical precedent, as is sometimes argued, but continued the evangelical support for liberty that has always made the United States a “dangerous nation” to tyrants. Along the way, this revisionism creates straw men, and co-opts or redefines terms that are central to the traditional understanding of U.S. foreign policy. It also seems to misunderstand grand strategy itself, focusing almost entirely on continuity of ends while ignoring the rather glaring discontinuities in the ways that generations of U.S. presidents have chosen to pursue them. Overall, the revisionist project fails in both of its tasks, which are: To make the case that the Bush administration took actions of which the Founding Fathers would have understood and approved; and by implication, to justify the unnecessary, tragic war in Iraq.     

The Use of Mitochondrial DNA Single Nucleotide Polymorphisms to Assist in the Resolution of Three Challenging Forensic Cases

Abstract:  Mitochondrial DNA (mtDNA) single nucleotide polymorphisms (SNPs) in an 11-plex assay were typed in three missing person cases involving highly degraded human remains. Unlike the traditional forensic approach to analyzing mtDNA which focuses on sequencing portions of the noncoding Control Region, this assay targets discriminatory SNPs that reside principally in the coding region. In two of the cases, the SNP typing successfully excluded one of two reference families that could not be excluded on the basis of mtDNA hypervariable region sequencing alone, and resulted in the final resolution of both decades-old cases. In a third case, SNP typing confirmed the sorting and reassociation of multiple commingled skeletal elements. The application of a specific mtDNA SNP assay in these cases demonstrates its utility in distinguishing samples when the most common Caucasian hypervariable region type is encountered in forensic casework.     

The influence of footwear sole hardness on slip initiation in young adults

Slips occur when the friction demand of an individual exceeds the friction available from the shoe/floor interface. Shoe sole hardness is one of the factors thought to influence friction demand and available friction. The purpose of this study was to determine the influence of footwear sole hardness on the probability of slip initiation. Forty young adults were randomized into a hard or soft sole group. Slip events during the slippery floor trials were documented using a motion analysis system. The proportion of slip events in the hard sole group was greater than that in the soft sole group. The difference between utilized and available friction accurately predicted 90% of slip outcomes. Our data support the premise that individuals wearing shoes with harder soles are at greater risk for slipping. The results of this study suggest that shoe sole hardness should be considered when designing footwear aimed at decreasing slip risk.     

Development and validation of videotaped scenarios: a method for targeting specific participant groups

Researchers using scenarios often neglect to validate perceived content and salience of embedded stimuli specifically with intended participants, even when such meaning is integral to the study. For example, sex and aggression stimuli are heavily influenced by culture, so participants may not perceive what researchers intended in sexual aggression scenarios. Using four studies, the authors describe the method of scenario validation to produce two videos assessing alcohol-related sexual aggression. Both videos are identical except for the presence in one video of antiforce cues that are extremely salient to the young heterosexual men. Focus groups and questionnaires validate these men's perceptions that (a) the woman was sexually interested, (b) the sexual cues were salient, (c) the antiforce cues were salient (antiaggression video only), and (e) these antiforce cues inhibited acceptance of forced sex. Results show the value of carefully selecting and validating content when assessing socially volatile variables and provide a useful template for developing culturally valid scenarios.     

The impact of state sentencing policies on the U.S. prison population

This article examines the aggregate effects of neoclassical sentencing reforms on three often contested outcomes of these reforms. The rate of new court commitments, the average length of time inmates serve, and prison population rates across the fifty U.S. states and the District of Columbia are examined. Data from 1973 to 1998 across these jurisdictions are analyzed using hierarchical multivariate linear models (HMLM). Results show that on the aggregate, sentencing reforms are not directly related to changes in state prison populations; however, abolition of parole is negatively associated with state prison population rates. Two types of sentencing reforms, the voluntary sentencing guidelines and the ‘three-strikes’ laws are indirectly related to changes in prison populations and have opposite influences on rates of new court commitments. Of six sentencing practices examined, not one is associated with length of incarceration. These results do not support the contention that neoclassical changes to the nation's sentence policies account for the rapid increase in the state prison populations between the early 1970s and late 1990s.
