“Public goods”: An exercise in calibration

This paper considers a measure of the “publicness” of goods and services implicit in responses that individuals make when asked about public sector spending. At the limit, all consumers consume equal amounts of a public good. Thus any differences between an individual's self-interest preferences and public-interest preferences cannot be based on differential provision, but only on differences in the individual's public- and self-interest utility functions. If we rule out the latter, self-interest and public-interest preferences for a pure public good are identical. Using sample survey data it is possible to calibrate the public good content of different public goods.     

Foreign Policy Analysis: Actor-Specific Theory and the Ground of International Relations

Examining the history, conceptual breadth, and recent trends in the study of foreign policy analysis, it is clear that this subfield provides what may be the best conceptual connection to the empirical ground upon which all international relations (IR) theory is based. Foreign policy analysis is characterized by an actor-specific focus, based upon the argument that all that occurs between nations and across nations is grounded in human decision makers acting singly or in groups. FPA offers significant contributions to IR—theoretical, substantive, and methodological—and is situated at the intersection of all social science and policy fields as they relate to international affairs. A renewed emphasis on actor-specific theory will allow IR to more fully reclaim its ability to manifest human agency, with its attendant change, creativity, accountability, and meaning.     

Doped hydrophobic silica nano- and micro-particles as novel agents for developing latent fingerprints

Novel hydrophobic silica based particles have been developed to visualise latent fingerprints. The composition of the particles has been designed to maximise both hydrophobic and ionic interactions between a variety of coloured and fluorescent reporter molecules and the silicate backbone within the particles. The resulting doped particles retain the incorporated dyes with high affinity. In addition, a variety of sub-particles have also been embedded to again produce coloured or magnetisable hydrophobic particles. The particles can be harvested as nanoparticles or microparticles. The former are applied to latent fingerprints as an aqueous suspension and the latter as a dusting agent using brushes or a magnetic wand. Examples of the prints produced using these agents are given. The resulting prints have good definition.     

Public perceptions of internet,familial and localised sexual grooming: Predicting perceived prevalence and safety

Abstract

This paper examines public perceptions of three sexual grooming types: computer-mediated sexual grooming (CMSG), familial sexual grooming (FSG) and localised sexual grooming (LSG). Using data from a national survey of 557 respondents from the United Kingdom, we tested models that predicted perceptions of the prevalence of CMSG, FSG and LSG and the perceived safety of internet, familial and localised grooming spaces. Media-related factors were the most significant in predicting higher levels of perceived prevalence of CMSG and disagreement in relation to safety of internet and public spaces. Knowledge of a grooming victim was most significant in predicting higher levels of perceived prevalence of FSG and LSG and higher levels disagreement in relation to the safety of the home. The findings suggest that the public express too little concern over familial sexual grooming and that initiatives should be introduced to make citizens more aware of the distinctions between types of sexual grooming behaviours, settings and offenders.
