Democratic Electoral Systems around the world, 1946–2011

This research note describes an update to Golder's (2005)Democratic Electoral Systems (DES) dataset. We extend the temporal scope of the original dataset by including all legislative and presidential elections that took place in democratic states from 2001 to 2011. In addition to significantly expanding the size of the DES dataset, we offer a simplified classification scheme for electoral systems. We also provide more detailed information about all democratic elections since 1946, including the dates for each round of elections as well as the rules used in different electoral tiers. A brief temporal and geographic overview of the data is presented.     

Religious Participation and Economic Conservatism

Why do some individuals engage in more religious activity than others? And how does this religious activity influence their economic attitudes? We present a formal model in which individuals derive utility from both secular and religious sources. Our model, which incorporates both demand‐side and supply‐side explanations of religion, is unusual in that it endogenizes both an individual's religious participation and her preferences over economic policy. Using data on over 70 countries from the pooled World Values Survey, we find that religious participation declines with societal development, an individual's ability to produce secular goods, and state regulations on religion, but that it increases with inequality. We also find that religious participation increases economic conservatism among the poor but decreases it among the rich. Our analysis has important insights for the debate about secularization theory and challenges conventional wisdom regarding the relationship between religious participation and economic conservatism.     

Evidence of a gene x environment interaction in the creation of victimization: results from a longitudinal sample of adolescents

A large body of research has revealed that aggressive personality traits and violent criminal behaviors are influenced by genetic factors. Surprisingly, however, no research has been devoted to investigating the potential genetic origins to adolescent victimization. In the current study, the authors address this gap in the literature by using data from the National Longitudinal Study of Adolescent Health (Add Health) to examine whether different variants of the dopamine D2 receptor gene (DRD2) are related to victimization, net of the effects of environmental measures. The results of the multivariate models revealed a significant gene X environment interaction in the creation of victimization for White males. Specifically, DRD2 interacted with delinquent peers to predict victimization. The authors discuss the implications of these findings.     

Structural validity of the posttraumatic stress disorder checklist among college students with a trauma history

The authors conducted confirmatory factor analyses to test three-factor and four-factor models of posttraumatic stress disorder (PTSD) using the PTSD Checklist with college students reporting a traumatic event history. The authors found support for the three-factor DSM-IV-based PTSD diagnostic model including reexperiencing, avoidance/numbing, and hyperarousal symptom factors, with slightly better support for a four-factor model separating the avoidance and numbing factors. Results further attest to the PTSD Checklist's construct validity, and to research finding that PTSD avoidance and numbing constructs are distinct.     

Designing policies that intentionally stick: policy feedback in a changing climate

Policy feedback is a widely used concept, but many who use it only focus on the positive and/or unintentional feedback effects of certain types of policy. The literature as a whole is therefore poorly equipped to make sense of the negative policy feedbacks that often appear in more regulatory areas such as climate change, where target groups are put under pressure to shoulder concentrated costs. Advocates of the ‘new’ policy design have an opportunity to address this gap by exploring how policy makers approach the design of policies that intentionally generate positive policy feedbacks and/or are resilient to negative ones. This paper contributes to that effort by identifying the conditions under which specific instrument designs are likely to have opportunity enhancing and/or constraining effects. It relates these expectations to a design situation where positive feedback seemed unlikely, and hence, the challenge of designing locked-in policies was correspondingly greater. It concludes by drawing on the findings of this exploratory case to investigate what the ‘new’ policy design can do better to explicate the temporal aspects of design.     

Variation in decomposition stages and carrion insect succession in a dry tropical climate and its effect on estimating postmortem interval

Insects have an important role in minimum postmortem interval (PMI_min) estimation. An accurate PMI_min estimation relies on a comprehensive study of the development and succession of local carrion insects. No published research on carrion insect succession exists for tropical north Queensland. To address this, we aimed to obtain preliminary observational data concerning the rate of decomposition and insect succession on pig carcasses in Townsville and compare these with other regions of Australia and overseas. Adult insects were collected daily from three pig carcasses for 30 d during summer and identified to family level. Observations of decomposition rate were made each day and progression through the stages of decomposition were recorded. Adult insects were identified to family and their presence/absence used as a proxy for arrival at/departure from the remains, respectively. These preliminary data highlight several interesting trends that may be informative for forensic PMI_min estimation. Decomposition was rapid: all carcasses were at the dry/remains stage by Day 5, which was substantially quicker than all other regions in the comparison. Differences were also observed in the presence/absence of insect families and their arrival and departure times. Given the rapid progression through early decomposition, we argue that later-arriving coleopteran taxa may be more forensically informative in tropical Australia, in contrast with temperate regions where Diptera appear most useful. This research contributes preliminary observational data to understanding insect succession patterns in tropical Australia and demonstrates the critical need for comprehensive local succession data for each climatic region of Australia to enable accurate PMI_min estimation. These data will inform future research targeted at gaining a more comprehensive understanding of insect succession in the Australian tropics.

Key points:

• We obtained preliminary observational data concerning the rate of decomposition and insect succession on pig carcasses in tropical Australia.
• Decomposition was rapid: all carcasses were at the dry/remains stage by Day 5.
• Coleopteran taxa may be more forensically informative in tropical Australia than dipterans.

     

Effects of childhood adversity on bullying and cruelty to animals in the United States: findings from a national sample

This study examined effects of type of and cumulative burden of childhood adversities on bullying and cruelty to animals in the United States. Data were derived from Waves I and II of the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews were completed by trained lay interviewers between 2001-2002 and 2003-2004. Although the effects of childhood adversity diminished with the inclusion of confounding variables, several adversities remained significant. For bullying, these included being made to do chores that were too difficult or dangerous, threatening to hit or throw something, pushing, shoving, slapping, or hitting, and hitting that left bruises, marks, or injuries. With respect to cruelty to animals, swearing and saying hurtful things, having a parent or other adult living within the home that went to jail or prison, and adult/other person fondling/touching in a sexual way were significant. The final models indicated that the cumulative burden of childhood adversities had strong effects on the increased likelihood of bullying behavior but not cruelty to animals.     

Characteristics of abstainers from substance use and antisocial behavior in the United States

Purpose

Whether lifetime abstainer's antisocial behavior is maladjusted or well-adjusted is unresolved. The aim of this study was to compare abstainers (defined as persons with no lifetime use of alcohol and other drugs and non-engagement in antisocial or delinquent behavior) with non-abstainers across a range of sociodemographic and mental health characteristics in the United States.

Methods

Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews (N = 43,093) using the Alcohol Use Disorder and Associated Disabilities Interview Schedule — DSM-IV version (AUDADIS-IV) were completed by trained lay interviewers between 2001 and 2002.

Results

The prevalence of abstaining was 11 percent. Abstainers were significantly more likely to be female, Asian and African-American, born outside the U.S., and less likely to be unemployed. Multivariate logistic regression analyses revealed that abstainers were significantly less likely to evidence lifetime mood, anxiety, or personality disorder compared to non-abstainers.

Conclusions

Findings indicate that abstainers are not maladapted and are comparatively more functional than non-abstainers.     

Forensic identification science evidence since Daubert: Part II--judicial reasoning in decisions to exclude forensic identification evidence on grounds of reliability

Many studies regarding the legal status of forensic science have relied on the U.S. Supreme Court's mandate in Daubert v. Merrell Dow Pharmaceuticals Inc., and its progeny in order to make subsequent recommendations or rebuttals. This paper focuses on a more pragmatic approach to analyzing forensic science's immediate deficiencies by considering a qualitative analysis of actual judicial reasoning where forensic identification evidence has been excluded on reliability grounds since the Daubert precedent. Reliance on general acceptance is becoming insufficient as proof of the admissibility of forensic evidence. The citation of unfounded statistics, error rates and certainties, a failure to document the analytical process or follow standardized procedures, and the existence of observe bias represent some of the concerns that have lead to the exclusion or limitation of forensic identification evidence. Analysis of these reasons may serve to refocus forensic practitioners' testimony, resources, and research toward rectifying shortfalls in these areas.     

Seniority and anti-competitive restrictions on the legislative common pool: tenure’s impact on the overall production of legislation and the concentration of political benefits

It is well established that geographic areas benefit, in terms of the share of government spending they capture, from having a legislator with longer tenure, holding constant the tenure of other legislators. However, the implications of this literature for how the total production of legislation changes if all members gained seniority is less clear. Increased levels and dispersion of seniority within Congress generate a cartel-like effect, whereby legislators restrict the quantity of legislation enacted and increase the average price of each passed bill. The analysis provides a natural experiment to gauge the impacts of the emergence of the congressional committee system.
