Foreign Policy Analysis: Actor-Specific Theory and the Ground of International Relations 总被引:1,自引:0,他引:1
Valerie M. Hudson 《外交政策分析》2005,1(1):1-30
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. 相似文献

Melo VF Barbar LC Zamora PG Schaefer CE Cordeiro GA 《Forensic science international》2008,179(2-3):123-134
The objective of this paper is to propose a soil characterization methodology for forensic use, based on physical (textural and spectroscopic analyses), chemical (extractions with hydrofluoric acid, ammonium oxalate, sodium dithionite-citrate-bicarbonate and NaOH solution) and mineralogical (thermal analyses and X-ray diffraction) analyses. The study was carried out in the State of Paraná, Brazil, in three neighborhoods of Curitiba city and in two cities within the Curitiba Metropolitan Region. In order to verify the similarity between samples, four composite samples (repetitions) were prepared in each of the five studied sites. It was obtained a great number of quantitative variables (56) from a reduced amount of soil sample (1g). The variables selected from the chemical extractions (16) were more precise in grouping similar samples (same horizon and sampling site) as well as in separating samples collected in different horizons or sites. Seven distinct groups were formed, each with high intragroup similarity, but the unexpected dispersion of two samples (from a total of 40 samples) reduced the distinction of three other studied groups. The placement of the two samples in a different group and the higher dispersion (24 samples) for samples collected in the city of Curitiba are due to the great pedological homogeneity of this area (physical-chemical horizon characteristics, soil color and parent material). The methodology used in this work (analytical method and data treatment) presents high potential for forensic studies and can be easily validated for other areas. 相似文献

Doped hydrophobic silica nano- and micro-particles as novel agents for developing latent fingerprints 总被引:1,自引:0,他引:1
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. 相似文献

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. 相似文献
