The effect of chlorine and hydrogen chloride on latent fingermark evidence

Exposure of forensic evidence to either hydrogen chloride or chlorine can result in acidification to such an extent that enhancement of fingermarks with ninhydrin or cyanoacrylate is inhibited. Under these circumstances, pretreatment of samples with volatile bases such as triethylamine or ethanolamine prior to using these enhancement techniques can lead to successful visualization of fingermarks. Alternatively, physical enhancement techniques such as powder dusting or small particle reagent can be used on acidified non-porous substrates, although the former technique is subject to increased background under such conditions.     

Who Cares? Explaining Perceptions of Compassion in Candidates for Office

Although prior research establishes the important effect perceptions of compassion have on vote choice, no systematic research examines why some candidates are perceived as more caring than others. In an era where television and social media put candidates’ personalities front and center, the lack of research on this topic is problematic. In this article, I explain why voters view some candidates as more caring than others. I argue that voters view politicians as compassionate when there is a commonality to link them. A commonality demonstrates an empathetic connection, or the ability to understand another’s feelings. This, in turn, convinces voters that the politician is sympathetic, or willing to do something to help. Without an empathetic connection, claims of sympathy by politicians will be viewed with greater levels of skepticism. I generate a classification system for the sources of commonality that link voters with politicians, including shared experiences, shared emotions, and shared identities. Using three survey experiments, I show how candidates can build empathic bonds with voters and better their chances of election.

     

Extraction procedures for some common drugs in clinical and forensic toxicology.

The results of four extraction systems for 86 drugs are reported. These systems were investigated with the view to obtaining a rapid, reliable, and efficient extraction technique in clinical and forensic toxicology.     

Locating the Issue Public: The Multi-Dimensional Nature of Engagement with Health Care Reform

This research examines in detail the structure of the issue public for health care reform, drawing from extensive, nationally representative survey data tapping general attentiveness to news and public affairs, specific interests in health care issues, and motivations (e.g., personal health and financial conditions) to follow health care reform issues. We furthermore adopt a multi-dimensional approach to defining the contours of the issue public for health care policy, separately studying its cognitive, affective, and behavioral underpinnings. Results indicate only weak interconnections across these dimensions—measured through health care knowledge, holding strong opinions on health care issues, and participation in health-related political activities, respectively—and somewhat different structural and motivational patterns underlying each. Theoretical, conceptual and methodological implications of these findings are discussed.Vincent Price and Joseph N.

Does the Charter Form Improve the Fiscal Health of Counties?

The public administration literature has paid attention to the relationship between the structure of a government and its ability to provide public services, reflected by its fiscal health. Although this literature has provided a useful understanding of government structures, it has largely ignored the charter form of government. As a formal written document that grants counties the power of self‐governance, a charter frees the county from state control. Included in this freedom is the ability to establish its own tax policies and services. In this article, the effects of charter adoption on fiscal health are tested using Florida county data from 1980 to 2012. The results show that the presence of a charter can improve the fiscal health of a county, which, in turn, can affect overall service provision.
