Perhaps no problem challenges the legitimacy of the criminal justice system more than the conviction of factually innocent individuals. Numerous highly publicized exonerations that occurred since 1989 have raised the visibility of wrongful conviction, eliciting the attention of both scholars and policy makers. Much of the research in this area focuses on the causes and incidence of the phenomenon. Despite the growing body of research, however, there has been no examination of how citizens view this problem. Using data from a statewide survey of Michigan residents, the present study aims to fill that gap in the literature by reporting on citizens’ attitudes regarding the issue of wrongful conviction. Overall, the results of this exploratory study suggest that respondents not only recognize the incidence of wrongful conviction but also believe that such errors occur with some regularity. Further results show that respondents believe wrongful convictions occur frequently enough to justify major criminal justice system reform. Attitudes varied significantly across demographic groups as well. Additional findings and policy implications are discussed.
Oxygenic photosynthesis fundamentally transformed all major biogeochemical cycles and increased the size and complexity of Earth's biosphere. However, there is still debate about when this metabolism evolved. As oxygenic photosynthesis is the only significant source of O 2 at Earth's surface, O 2-sensitive trace element enrichments and isotopic signatures in Archean sedimentary rocks can potentially be used to determine the onset of oxygenic photosynthesis by tracking shifts in the oxidative capacity of Earth's surface environment. Here, we present an extensive new Archean U isotope record from iron formations, organic-rich shales, and paleosols. Variability in 238 U values gradually increased from Archean to Phanerozoic, consistent with current view of gradual oxidation of Earth's surface. In addition, statistical analysis on available 238 U data indicates a turning point of 238 U variability at roughly 3.0 billon years ago. We suggest that such a turning point in 238 U variability indicates the initiation of relatively large-scale oxidative weathering of U(IV)-bearing minerals, implying that oxygenic photosynthesis may have evolved before 3.0 billion years ago.
A growing body of evidence has highlighted the relationship between narcissism and violence. Importantly, however, the predominance of this evidence comes from experimental tests or small-scale samples that most often overlook the contribution of low self-control to explicating the relationship. The present study refers to the National Epidemiological Study of Alcohol and Related Conditions (NESARC) to assess narcissism, low self-control, and violence among a nationally representative sample. Using Latent Class Analyses (LCA), four classes of individuals are identified, and multinomial regression models indicate that narcissism and low self-control are associated with a range of violent acts among these groups. Most importantly, results show that the class of individuals that is high in narcissism and deficient in self-control is far and away the most prone to violence. Together, these findings lend important nationally representative support to recent experimental and meta-analytical conclusions suggesting that the co-occurrence of narcissism and low self-control has significant implications for our understanding of violence. Limitations of this study and avenues for future research are discussed.T he etiology of violence has received a wealth of theoretical and empirical attention from a range of disciplines that have offered a diversity
Despite an emerging body of research indicating that immigrants are less likely than native-born Americans to engage in crime and antisocial behavior, less attention has focused specifically on intimate partner violence (IPV) perpetration among immigrant populations. We address this gap by using data from Wave II of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and compare immigrants from Asia, Africa, Europe, and Latin America to native-born Americans with respect to multiple forms of IPV. After controlling for an extensive array of confounds, results indicate that in the aggregate, immigrants are significantly more likely to perpetrate IPV. However, examination of major world regions indicates these results are driven by Latin American immigrants. Immigrants from Asia, Africa, and Europe report a lower prevalence of IPV perpetration than native-born Americans. This study extends prior research on the immigrant paradox and suggests that future studies take into account regional heterogeneity when examining IPV and other forms of violence in immigrant populations.
Recent studies have directed attention to the nature of romantic involvement and its implications for offending over the life course. However, this body of research has overlooked a defining aspect of nonmarital romantic relationships: Most come to an end. By drawing on insights from general strain theory, the age‐graded theory of informal social control, and research on delinquent peer exposure, we explore the impact of romantic dissolution on offending and substance use during late adolescence and emerging adulthood. Using data from the 1997 cohort of the National Longitudinal Survey of Youth, we arrive at three general conclusions: 1) Experiencing a breakup is directly related to a range of antisocial outcomes; 2) the effect of a breakup is dependent on post‐breakup relationship transitions; and 3) a breakup is associated with increases in offending and substance use among males and in substance use among females. We conclude with a discussion of the implications of our findings for the future of research on romantic involvement and crime over the life course.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
