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.     

Change in Self-Esteem and Physical Aggression During Treatment for Partner Violent Men

The role of low self-esteem in aggressive behavior has been questioned by theorists who claim that inflated, rather than deflated, self-esteem is associated with violence, and that societal efforts to increase self-esteem may actually increase, rather than decrease, violent behavior. This conjecture was tested in two treatment samples of partner violent men, one (n = 61) that received a behavioral intervention, and one (n = 107) that received a workshop program designed to enhance compassion for self and others. Both samples reported significant reductions in relationship violence perpetration and significant increases in self-esteem from pre- to post-treatment. In both samples, change in self-esteem was inversely correlated with change in physical aggression. Follow-up data from victims were available for one of the samples, and revealed that self-esteem and its enhancement during treatment did not significantly predict relationship violence during the year after treatment. These results indicate that self-esteem enhancement during treatment for partner violent men is correlated with violence reduction, and does not increase the risk for subsequent relationship aggression.     

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.     

Comparing the Politics of Hydraulic Fracturing in New York,Colorado, and Texas

The purpose of this article is to analyze perceptions and activities of policy actors, who are actively involved in or knowledgeable about the politics of hydraulic fracturing in New York, Colorado, and Texas. The analysis is guided by research questions drawn from the Advocacy Coalition Framework that focus on policy actors’ policy positions, problem perceptions, political capacity, activities, and interactions. In doing so, we examine the differences between those policy actors who are opposed to hydraulic fracturing relative to those who support hydraulic fracturing across the three states using data from online surveys administered in 2013 and 2014. The results show polarization between opponents and proponents in their policy positions on hydraulic fracturing, which are associated with problem perceptions. Proponents and opponents of hydraulic fracturing also have different capacities, activities, and interactions. The results are similar across states but not without nuanced differences, including greater polarization in New York, higher levels of government support for proponents of hydraulic fracturing in Texas, and more frequent coalition building in Colorado.
