This article investigates the Patagonian ecotourism industry and the spatial production of gender privilege. The analysis attends to how the spatial practices of park rangers, tourism guides and climbers create a gendered space of capital accumulation that devalues and marginalises othered subjects – such as women and non-alpine men – within specific domains of nature. Developing the concept of a figuration of capital, this article argues that the ecotourism industry has facilitated the rise of an alpine masculine subject based upon key bodily values: robust physicality, a conservationist ethic and heroic narration about engaging wilderness.  相似文献

Over the last few decades, the use of non-intrusive geophysical techniques, which allows for coverage of an entire crime scene in a reasonable amount of time, in forensic investigation has increased. In this study, we analyze the effectiveness of ground-penetrating radar (GPR) in forensics. Experimental scenes were simulated and some of the most commonly buried items in actual crime scenes were introduced, such as bone remains, guns and drug caches. Later, a GPR survey was conducted on the experimental grids with a 500 MHz antenna. The final purpose was to characterize the radar wave response expected for each set of remains to assist with its identification in later actual investigations. The results collected provided promising information that can be used when surveying real cases. Nevertheless, there were some interpretational difficulties regarding the sizes of the items and the electromagnetic properties of the materials. For these cases, finite-difference time-domain modeling was employed to achieve an advanced interpretation of the field data. The simulated models used were built from accurate geometric data provided by photogrammetric methods, which replicate the experimental scenes in fine detail. Furthermore, this approach allowed for the simulation of more realistic models, and the synthetic data obtained provided valuable information for assisting in the interpretation of field data. As a result of this work, it was concluded that GPR can be an effective tool when searching for a variety of materials during a crime scene investigation.  相似文献

Rural water planners assume the positive impacts of community water projects are spread evenly across the population. We test this assumption by looking at the distribution of benefits within communities that received handpumps in rural Mozambique. Using survey and qualitative data we analyse the characteristics of those groups who benefited from the handpumps and also explore household decision-making processes. Handpump use was determined by distance, availability of other sources, perceptions of water quality, political affiliation, and wealth. We argue that the handpumps reinforced existing social divisions related to income and political affiliation and created new geographic divisions within communities.  相似文献

This article analyzes the positions of top public officials on an equity‐efficiency trade‐off and the determinants of those positions. It uses data from a survey across 14 European countries. The results show that differences in public officials' positions on equity‐efficiency are related to the context in which they work and to their personal background. Officials at the top of the hierarchy and those with a business or economics education are more oriented toward efficiency. Additionally, results show important differences associated with country administrative culture, including a stronger equity orientation in Scandinavian countries, and a stronger efficiency orientation in Southern European countries. The positions of public officials reflect those held by citizens in their country, confirming the contextualized nature of administrative values. This article contributes to understanding the determinants of public officials' dominant values.  相似文献

In order to detect switching and/or manipulation of samples, the owner of a stallion asked our lab to perform a DNA test on a positive doping urine sample. The objective was to compare the urine DNA profile versus blood and hair DNA profiles from the same stallion. At first, 10 microsatellite markers were investigated to determine the horse identity. No results were obtained when horse specific markers were typed in the urine sample. In order to confirm the species origin of this sample we analyzed the mitochondrial cytochrome b gene. This analysis from blood and hair samples produced reproducible and clear PCR-RFLP patterns and DNA sequence match with those expected for horse, while the urine sample results were coincident with human. These results allowed us to exclude the urine sample from the questioned stallion and determine its human species origin, confirming the manipulation of urine sample.  相似文献

Immunohistochemistry (IHC) technique is an alternative toxicological analysis to detect drugs in insects of forensic importance, but it requires thorough histological procedures. In this study, we tested different fixatives—phosphate‐buffered paraformaldehyde 4% (PP), Carnoy's fluid (CF), Kahle's solution (KS), ethanol in different concentrations, and ethanol associated to PP and CF, time of fixation and histological processes for dipteran larvae's tissue, aiming to develop a sample preparation protocol for IHC application. A suitable fixation was achieved using PP for 12 and 24 h, CF for 3 h, 70% ethanol for 19 days, and 70% ethanol/CF for 2 h/3 h. Postfixation using negative pressure, two immersions in xylene for 30 min each, and one in xylene plus paraffin for 45 min increased tissue preservation. An immunohistochemical test for cocaine detection was performed using monoclonal benzoylecgonine antibody from mouse, peroxidase‐conjugated anti‐mouse IgG and visualized by 3,3′‐diaminobenzidine method showed these histological procedures didn't compromise antigenicity.  相似文献
