Traumatic brain injury,temperament, and violence in incarcerated youth: a mediation analysis based on Delisi and Vaughn’s theory of temperament and antisocial behavior

Traumatic brain injury (TBI) is associated with violent behavior. A possible key mechanism to explain the relationship between TBI and violence is DeLisi and Vaughn’s temperament-based theory of antisocial behavior. Accordingly, the current study investigates whether temperament – the combination of effortful control and negative emotionality – mediates the relationship between TBI and violent behavior within incarcerated youth. A non-probability sample of youth (N?=?227) incarcerated in two long-term residential facilities completed a comprehensive assessment tool that collected data on TBI, temperament, childhood trauma, substance use, mental illness, and a variety of demographic characteristics. Preliminary results showed TBI significantly increased violent behavior, adjusting for confounds. Then, mediation analysis found that temperament accounted for 54% of the total effect between TBI and violence. The study findings show the potency of DeLisi and Vaughn’s temperamental construct in explaining the relationship between TBI and violent behavior within a sample of incarcerated youth. The dynamic interplay between effortful control and negative emotionality appears to be an important mechanism related to violent behavior. Both temperament constructs should be the focus of future assessment and intervention among incarcerated youth with TBI.     

The Conceptual Compatibility Between Green Criminology and Human Security: A Proposed Interdisciplinary Framework for Examinations into Green Victimisation

The overriding aim of this paper is to develop a conceptual framework that can be used to systematically examine the victimisation from environmental or green crime. By analysing the conceptual and pragmatic compatibilities between two distinctive academic fields of green criminology and human security (HS) and by discussing the impacts of timber trafficking on HS, it is argued that it would be logical, achievable and fruitful to employ a broad HS perspective to advance the understanding of the mechanism of green victimisation with a focus on human victims.     

The distribution of conflict and attention across energy infrastructure

Across the world, public administration and policy decisions are related to diverse levels of conflict and attention. However, the degree and variance of conflict and attention remain largely unspecified. This article examines how types of energy infrastructure and characteristics of project location are associated with the distribution of conflict and attention around the energy infrastructure siting process. Our empirical focus is on gas pipelines, electricity transmission lines, solar power projects, and wind power projects across the United States in 2018. Primarily relying on regression analysis and interviews, this article finds differences in the distribution of conflict and attention intensity within and between these energy infrastructure types, with gas pipelines and wind power projects presenting relatively higher conflict and attention intensities. However, conflict and attention are skewed to low intensities across infrastructure types. Characteristics of project locations that are positively associated with high conflict and attention intensity include the proportion of Democratic voters and the level of urbanization in the places where projects are sited. In contrast, the proportion of Black or Hispanic residents is negatively associated with high conflict and attention intensity.     

Policy conflicts in shale development in China and the United States

Policy conflicts are ubiquitous in many countries. Yet research on policy conflict is typically based on cases in western, democratic countries. As a result, little is known about the characteristics of policy conflicts in non-western countries, such as China, or how these characteristics compare to western contexts. The Policy Conflict Framework (PCF) was recently developed to help scholars identify, diagnose, and compare policy conflict characteristics. This research uses the PCF to guide a comparative analysis of the nature of policy conflicts in China and the United States. With interview data on policy actors from Chongqing, China and Colorado, USA, we present the findings by comparing the differences and similarities of policy conflicts in the two countries around shale oil and gas development. We conclude with the strengths and limitations of this comparative study of policy conflicts in China and other national contexts, along with recommendations for conducting PCF research in China.     

Raman Microspectroscopic Mapping: A Tool for Identification of Fused Materials in Fire Debris

Examination of fire debris can provide information about the types of materials which were present at the time of the fire to give insights for fire scene reconstruction and understanding compartment fire dynamics. This paper demonstrates the ability of Raman spectroscopy for material identification postfire in complex situations, such as the production of fused masses during fire dropdown. A validated Raman spectral library is combined with Raman mapping in three fire case studies, to determine the individual materials in the fused masses formed. The case studies accessed material combinations of several common polymers. Raman mapping was carried out on a 10 μm × 10 μm square of the masses. Material identification using this technique ranged from a high of 85% match to a low of 40% match. This work demonstrated that complex masses found in the fire debris can be resolved into the individual material components for identification and spatial distribution.
