Explaining the unpopularity of public funding for congressional elections

This article uses data from the 2008 Cooperative Congressional Election Study to explain weak support for public financing of congressional campaigns. Previous studies lack theory to explain variation in support and use a flawed measure of the dependent variable. We argue that low support reflects a failure resulting from a collective action dilemma. Citizens desire a campaign finance system that weans politicians from private donors, but are unwilling to pay a small amount in taxes to support public financing. In contrast to conventional wisdom, we show that support for public financing is highest among those perceived to benefit the most from the current system. Our results suggest that most Americans would rather not pay for politics, and that reform proposals must avoid incurring transparent costs on individual citizens to pay for reform.     

Using Gas Chromatography with Ion Mobility Spectrometry to Resolve Explosive Compounds in the Presence of Interferents*

Abstract: Ion mobility spectrometry (IMS) is a valued field detection technology because of its speed and high sensitivity, but IMS cannot easily resolve analytes of interest within mixtures. Coupling gas chromatography (GC) to IMS adds a separation capability to resolve complex matrices. A GC‐IONSCAN^® operated in IMS and GC/IMS modes was evaluated with combinations of five explosives and four interferents. In 100 explosive/interferent combinations, IMS yielded 21 false positives while GC/IMS substantially reduced the occurrence of false positives to one. In addition, the results indicate that through redesign or modification of the preconcentrator there would be significant advantages to using GC/IMS, such as enhancement of the linear dynamic range (LDR) in some situations. By balancing sensitivity with LDR, GC/IMS could prove to be a very advantageous tool when addressing real world complex mixture situations.     

The role of broken homes in the development of self-control: A propensity score matching approach

Criminologists have frequently identified broken homes as a risk factor for involvement in crime and delinquency. The association between broken homes and antisocial behavior has been replicated in numerous studies, and despite being entrenched within the study of delinquency, there is a lack of research examining its impact on the development of self-control. This is somewhat surprising given that low self-control has been shown to be a robust and consistent predictor of antisocial behavior. We address this void in the literature by examining the role of broken homes in the development of self-control in early childhood using propensity score matching. Analysis of the Fragile Families and Child Wellbeing Study revealed a statistically significant association between broken homes and the development of self-control prior to matching. After matching on six key maternal and paternal covariates, the association between broken homes and levels of self-control was no longer statistically significant. We discuss what these findings mean for criminological theories.     

Juvenile arrest rates for burglary: A routine activities approach

Juveniles comprise a substantial portion of the offenders arrested for burglary in the United States each year. Using a Hierarchical Multivariate Linear Model, the current research examines juvenile burglars, by gender, utilizing a routine activities approach. This analysis was performed using data on the thirty five largest cities in Texas, between 1990 and 2004. Increased incidents of juvenile arrests for burglary, in both genders, occurred where there were high levels of poverty and low levels of female headed households. Juvenile males appeared to be arrested more for burglary in areas where there were high levels of unemployment and non-white individuals, while juvenile females were arrested for burglary in places where there were higher numbers of males between the ages of 19 and 24 years. Results suggest that the current measures of routine activities theory better explains variation in juvenile male arrests for burglary.     

Why Evolutionary Biology Is (So Far) Irrelevant To Legal Regulation

Evolutionary biology – or, more precisely, two (purported) applications of Darwin’s theory of evolution by natural selection, namely, evolutionary psychology and what has been called human behavioral biology – is on the cusp of becoming the new rage among legal scholars looking for interdisciplinary insights into the law. We argue that as the actual science stands today, evolutionary biology offers nothing to help with questions about legal regulation of behavior. Only systematic misrepresentations or lack of understanding of the relevant biology, together with far-reaching analytical and philosophical confusions, have led anyone to think otherwise. Evolutionary accounts are etiological accounts of how a trait evolved. We argue that an account of causal etiology could be relevant to law if (1) the account of causal etiology is scientifically well-confirmed, and (2) there is an explanation of how the well-confirmed etiology bears on questions of development (what we call the Environmental Gap Objection). We then show that the accounts of causal etiology that might be relevant are not remotely well-confirmed by scientific standards. We argue, in particular, that (a) evolutionary psychology is not entitled to assume selectionist accounts of human behaviors, (b) the assumptions necessary for the selectionist accounts to be true are not warranted by standard criteria for theory choice, and (c) only confusions about levels of explanation of human behavior create the appearance that understanding the biology of behavior is important. We also note that no response to the Environmental Gap Objection has been proffered. In the concluding section of the article, we turn directly to the work of Owen Jones, a leading proponent of the relevance of evolutionary biology to law, and show that he does not come to terms with any of the fundamental problems identified in this article.     

Armed,but too dangerous? Factors associated with citizen support for the militarization of the police

Images of police officers riding in armored vehicles and carrying military-grade weapons have become part of the public consciousness following the events in Ferguson, Missouri and several other high-profile police–citizen encounters. Although a great deal of research has investigated how and why US citizens perceive the police in various ways, almost no empirical work has asked how citizens perceive the militarization of the police. The current study analyzes data from a survey of 1005 US citizens to identify characteristics that are related to support for the use of military weapons and vehicles by local police departments. The results indicate that several demographic factors and perceptions of crime and the police are significantly related with citizen support for the militarization of the police. The implications of this research are discussed.     

Secondary Confessions as Post-identification Feedback: How Jailhouse Informant Testimony Can Alter Eyewitnesses’ Identification Decisions

Prior research has shown that primary confession evidence can alter eyewitnesses’ identifications and self-reported confidence. The present study investigated whether secondary confession evidence from a jailhouse informant could have the same effect. Participants (N?=?368) watched a video of an armed robbery and made an identification decision from a photo lineup. Except for those in the no-feedback conditions, all participants then read that certain lineup members either confessed to the crime, denied involvement, or were implicated by a jailhouse informant. Jailhouse informant testimony implicating the identified lineup member led participants to have significantly higher confidence in their identification. In contrast, jailhouse informant testimony that implicated a lineup member other than the identified led participants to have significantly lower confidence in their initial identification, and 80% of these witnesses changed their identification. These results indicate that jailhouse informant testimony can influence eyewitnesses’ confidence and their identification decisions.     

Trends in Mortality of the Soviet Population

Two prominent American demographers present an up-to-date study of trends and countertrends in mortality of the Soviet population; discussed are variations (by republic and over time) in life expectancy, infant mortality, and mortality in the working ages. Analyzing trends since 1959, the authors highlight problems relating to the quality and interpretation of pertinent statistical data of Soviet origin. Distinguishing real trends from pseudotrends, they evaluate mortality differences among regions and illustrate a more favorable long-term trend in mortality than suggested by official figures (nonetheless, because of error in official statistics, actual rates are generally higher).

What's the Problem in Public Sector Workforce Recruitment? A Multi-Sector Comparative Analysis of Managerial Perceptions

Public sector workforce recruitment is problematic, but the nature of that problem is not clearly defined. Workforce recruitment is essentially a matching problem that requires managers to recruit desired employees in available labor pools. This research asks whether sectoral differences and competition for labor affect whether public managers frame the major problem of workforce recruitment as the size, qualifications, or work ethic of the labor pool. Using survey data from about 2,300 managers from two US states, problem attributions are modeled using multinomial logit. The findings suggest that the public and nonprofit sectors find it more problematic to recruit qualified employees than the private sector, but public and nonprofit agencies hold a comparative advantage over the private sector in recruiting employees with sufficient work ethic. Therefore, public and nonprofit managers should emphasize retention and training to leverage their comparative advantage in recruiting employees with work ethic while addressing a comparative disadvantage in recruiting qualified employees.
