War and Peace: A Diachronic Social Biogeography of Life History Strategy and Between-Group Relations in Two Western European Populations
No full textWe report successful diachronic replication of two major sets of prior findings in the social biogeography of human life history (LH) strategy: (1) the constructive replication of the diachronic changes in the latent hierarchical structure of intelligence in Britannic populations, but as presently applied to the latent hierarchical structure of human LH strategy, now cross-validated in both Britannic and Gallic populations; and (2) the diachronic replication in both Britannic and Gallic populations of the structural relations found synchronically among human LH strategy, between-group competition, and economic productivity in cross-sectional data on contemporary samples of both national and subnational polities. In addition, a supplementary methodological objective was: (3) the convergent validation of diachronic lexicographic measures of LH strategy with respect to more traditional non-lexicographic indicators of LH strategy, such as infant mortality rates, total fertility rates, and life expectancies. We obtained complete configural invariance across Britannic and Gallic biocultural groups, meaning that the same model predictors were statistically significant, but incomplete metric invariance, meaning that most but not all model parameter estimates were statistically equivalent in magnitude and direction. All new results obtained from diachronic data in Britannic populations were replicated almost perfectly in Gallic populations
THE EFFICACY OF INTERMITTENT PNEUMATIC COMPRESSION AS A SUBSTITUTE FOR MANUAL LYMPHATIC DRAINAGE IN COMPLETE DECONGESTIVE THERAPY IN THE TREATMENT OF BREAST CANCER RELATED LYMPHEDEMA
No full textThe aim of this study is to evaluate the efficacy of intermittent pneumatic compression (IPC) as a substitute for manual lymphatic drainage (MLD) in complete decongestive therapy (CDT) for treatment of advanced stages of breast cancer-related lymphedema. In this randomized, single-blind, controlled study, 46 patients with breast cancer-related lymphedema were divided into 2 groups. Both MLD with compression bandage (CB) group (n=24) and IPC with CB group (n=22) received treatment 3 days a week for 5 weeks. Home exercise program was also given to all patients. At the end of the 5th week, patients were treated with a daily 23-hour compression garment and home exercise routines. Assessments were taken at baseline, the fifth week, and the third month. Arm circumference was measured at 5 different areas, shoulder range of motion (ROM) was evaluated with a goniometer, pain, and tightness, and heaviness sensations were assessed with visual analog scale. Both groups had similar demographic and clinical characteristics (p 0.05). There were no significant differences between groups and both groups showed significant improvement (p 0.05) in the five measurement levels of the arm circumference at the fifth week and third month. Similarly, shoulder ROM, pain, tightness, and heaviness sensations improved in both groups (p 0.05). Both MLD and IPC as a component of CDT were found successful at 5 weeks and 3 months without superiority to each other

Socializing the rain: human adaptation to ecological variability in a fishery, Mweru-Luapula, Zambia
No full textAbstract Rainfall drives fishery fertility in Mweru-Luapula, thus rainfall variability contributes to frequent changes in fishing catches. Fishers and traders have adapted their institutions to this variable ecology in a variety of ways, including learning to read the fishery for productive periods and practicing multiple modes of income procurement. By accurately identifying inter-annual, inter-decadal, and longer spans of rainfall trends, future high and low yields can be forecast. This article presents and analyzes annual rainfall in the fishery from 1916-1992 and quantitative fish market data comprised of observed fish catch numbers by species in three markets from September 2004 to September 2005. It uses political ecology to better understand fish production, trade, and subsistence in this South-Central African freshwater fishery. We combine qualitative analysis of fisher and marketer perceptions of the fishery and knowledge of rainfall patterns to show how human behavior is not "tragically" driven, but instead based on the state of the ecological, sociocultural, and socioeconomic environment at a given time.Keywords: African freshwater fisheries, rainfall modeling, political ecology, Mweru-Luapula, Zambia, climate chang
Large-scale mining and ecological imperialism in Africa: the politics of mining and conservation of the ecology in Ghana
No full textThe article draws on the insights of political ecology to illuminate the politics shaping the enforcement of environmental regulation in the mining sector of Ghana. We argue that the Ghanaian state uses strong-arm measures against artisanal and small-scale mining (ASM) operators, particularly, the subaltern classes engaged in the industry for survival. Periodically, the state deploys the military and the police to clamp down on ASM for destroying the environment, but treats with kid gloves foreign companies engaged in large-scale mining (LSM), wreaking similar disastrous ecological effects on mining communities. The state believes that LSM by foreign companies is a source of foreign direct investment (FDI) and foreign mining companies should be incentivized to come and stay in the country. Presented in broad-brush strokes as illegal (galamsey), the Ghanaian state sees ASM as an environmental menace to be fought with all the coercive apparatuses that it can command. Disputing this claim, the article argues that mining-FDI is essentially ecological imperialism, wreaking havoc on the ecosystem of mining communities whose livelihood strategies are in conflict with the accumulation and political interests of foreign mining companies and the Ghanaian political class respectively. The article demonstrates that concerns over the harmful impacts of mining on the ecology of Ghana are neither class-neutral nor free of politics. They are rather highly imbricated in power structures and relations, in which the interest of the ruling class is supreme in the enforcement of environmental regulations in Ghana. The paradox of the biases of the Ghanaian state against ASM, particularly ASM operated by its own citizens for survival, and in favor of foreign mining companies engaged in LSM for profits, is explained with the insights of ecological imperialism.Keywords: Large-scale mining, artisanal and small-scale mining, Operation Vanguard, Ghanaian state biases, ecological imperialis
'That's the problem with that lake; it changes sides': mapping extraction and ecological exhaustion in the Atacama
No full textMultiple dynamics produce the ecological present. For the past 30 years or more, in the southern Atacama salt pan (Salar) in northern Chile, extractive industries have been accumulating minerals and water in exhaustive quantities, taking ever more than may be regenerated. However, the exhaustion of the Salar de Atacama involves a more complex set of symptoms than demonstrable environmental depletion. Fragmented scientific knowledge of the salt pan due to the privatization of water and under-regulation of mining provides a partial explanation for this complexity. In this article, we discuss these political conditions of environmental knowledge and, using a range of methodologies, we show that the scale of resource extraction threatens social and environmental harm and exhaustion may manifest in unexpected ways. We used remote sensing data to elaborate maps that reflect environmental change (1985-2017), relative to the intensification of extractive activity for copper and lithium salts in the area. Using these data, we undertook ethnographic and participatory mapping work to discuss with people from the Peine Indigenous community how they have experienced ecological change related to mineral and water extraction in the southern Salar. A review of the historical and archaeological material helps us to show the depth of Indigenous people's relationships to and knowledge of the salt pan and surrounds, and how social memory may be ecological. Combining the different results of our research, we argue that ecological exhaustion emerges from social, environmental and political conditions driven by both tangible and uncertain impacts of industrial extraction. Revealing these conditions of exhaustion raises key questions about the complexity of the effects of extraction.Keywords: Indigenous peoples; Salar de Atacama; participatory mapping; mining; water right
Dress, Class, and Caricature in Late Eighteenth Century England
No full textIn this paper I analyze a sample of satirical prints from later eighteenth century London, identifying the ways in which class distinctions were addressed through depictions of dress. I argue that these images were an uneasy response to the destablizing effects of industrialization on sartorial literacy
