Life Without Parole Sentencing in North Carolina

What explains the puzzle of life without parole (LWOP) sentencing in the United States? In the past two decades, LWOP sentences have reached record highs, with over 50,000 prisoners serving LWOP. Yet during this same period, homicide rates have steadily declined. The U.S. Supreme Court has limited the use of juvenile LWOP in Eighth Amendment rulings. Further, death sentences have steeply declined, reaching record lows. Although research has examined drivers of incarceration patterns for certain sentences, there has been little research on LWOP imposition. To shed light on what might explain the sudden rise of LWOP, we examine characteristics of the more than 1,627 cases in which LWOP was imposed from 1995 to 2017, in North Carolina, one of the states that imposes the largest numbers of these sentences. We begin by analyzing defendant race, crime, and sentence patterns by county. We associate LWOP with homicide rates, and examine interactions between homicide, victim race, and prior LWOP sentencing. This first empirical analysis of adult LWOP sentences finds important local variations in its imposition. We find that as the homicide rate increases within a county, we observe fewer LWOP sentences. We find that fewer LWOP sentences are predicted to occur as the number of black victim homicides increase in a county, but no such relationship is found when considering the number of white victim homicides. Finally, we find a strong path dependency and concentration of LWOP sentences in counties, where counties that have imposed LWOP sentences in the past are more likely to continue to do so. These findings have implications for efforts to reconsider the most severe sentences in the U.S., and they suggest that prosecutorial discretion in seeking long sentences will be important subjects for future research and policy

ROCs in Eyewitness Identification:Instructions versus Confidence Ratings

From the perspective of signal-detection theory, different lineup instructions may induce different levels of response bias (Clark, 2005). If so, then collecting correct and false identification rates across different instructional conditions will trace out the ROC – the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of a mock crime, participants were presented with instructions followed by a 6-person simultaneous photo lineup. The ROCs from both methods were similar, but they were not exactly the same. These findings have potentially important policy implications for how the legal system should go about controlling eyewitness response bias

Understanding how men experience, express and cope with mental distress: where next?

In line with the shift towards prioritising lay accounts and narratives of chronic illness in sociology, there is an emerging literature on men, their subjectivities and experiences of mental distress. We argue in this paper that subjectivities and distress among men are an important area for critical sociological research. Very little is known about men's subjectivities or the meanings they give to - and how they cope with or seek help for - distress. At the same time, current theories of gender relations, performativity and wellbeing as they pertain to men are likely to shed further light on subjectivity and distress. However, current theories (and qualitative research involving men and women) are pointing to considerable complexity. In this paper, we outline what is known about distress and men, and consider the utility of gender relations, performativity, subjectivities and wellbeing for a better understanding of distress. We also ask: What other factors influence distress, and how should these be considered in relation to men and masculinities? What are the implications for research and policy
