The Perceived Benefits of Height: Strength, Dominance, Social Concern, and Knowledge among Bolivian Native Amazonians
Research in industrial countries suggests that, with no other knowledge about a person, positive traits are attributed to taller people and correspondingly, that taller people have slightly better socioeconomic status (SES). However, research in some non-industrialized contexts has shown no correlation or even negative correlations between height and socioeconomic outcomes. It remains unclear whether positive traits remain attributed to taller people in such contexts. To address this question, here we report the results of a study in a foraging-farming society of native Amazonians in Bolivia (Tsimaneā)āa group in which we have previously shown little association between height and socioeconomic outcomes. We showed 24 photographs of pairs of Tsimaneā women, men, boys, and girls to 40 women and 40 men >16 years of age. We presented four behavioral scenarios to each participant and asked them to point to the person in the photograph with greater strength, dominance, social concern, or knowledge. The pairs in the photographs were of the same sex and age, but one person was shorter. Tsimaneā women and men attributed greater strength, dominance, and knowledge to taller girls and boys, but they did not attribute most positive traits to taller adults, except for strength, and more social concern only when women assessed other women in the photographs. These results raise a puzzle: why would Tsimaneā attribute positive traits to tall children, but not tall adults? We propose three potential explanations: adultsā expectations about the more market integrated society in which their children will grow up, height as a signal of good child health, and childrenās greater variation in the traits assessed corresponding to maturational stages

The Spanish masters : the 16th century presence in the Universal Declaration of Human Rights
textThe Universal Declaration of Human Rights (UDHR) was adopted in 1948 as a response to the atrocities of the Second World War. This analysis seeks to trace the influence of three Spanish masters of the 16th century, Las Casas, Vitoria and SuƔrez on the rights language and theory presented in the UDHR. Particular attention is given to the debates surrounding the Amerindians and the Spanish Conquest of the Americas, as well as burgeoning discussions of international relations in the emerging modern age. These debates provided the context in which the three theorists developed their understanding of rights and how the rule of the natural law was to be understood in the modern age. While the vision of the UDHR still remains to be achieved, the influence of the three masters is clearly recognized and much credit is due them for laying the foundation of modern human rights theory.Governmen

Visual field defects after radiosurgery for mesial temporal lobe epilepsy
PurposeGamma knife radiosurgery (RS) may be an alternative to open surgery for mesial temporal lobe epilepsy (MTLE), but morbidities and the anticonvulsant mechanisms of RS are unclear. Examination of visual field defects (VFDs) after RS may provide evidence of the extent of a postoperative fixed lesion. VFDs occur in 52-100% of patients following open surgery for MTLE.MethodsThis multicenter prospective trial of RS enrolled patients with unilateral hippocampal sclerosis and concordant video-electroencephalography (EEG) findings. Patients were randomized to low (20 Gy) or high (24 Gy) doses delivered to the amygdala, hippocampal head, and parahippocampal gyrus. Postoperative perimetry were obtained at 24 months after RS. Visual field defect ratios (VFDRs) were calculated to quantify the degree of VFDs. Results were contrasted with age, RS dose and 50% isodose volume, peak volume of radiation-induced change at the surgical target, quality of life measurements, and seizure remission.Key findingsNo patients reported visual changes and no patients had abnormal bedside visual field examinations. Fifteen (62.5%) of 24 patients had postoperative VFDs, all homonymous superior quadrantanopsias. None of the VFDs were consistent with injury to the optic nerve or chiasm. Clinical diagnosis of VFDs correlated significantly with VFDRs (p = 0.0005). Patients with seizure remission had smaller (more severe) VFDRs (p = 0.04). No other variables had significant correlations.SignificanceVFDs appeared after RS in proportions similar to historical comparisons from open surgery for MTLE. The nature of VFDs was consistent with lesions of the optic radiations. The findings support the hypothesis that the mechanism of RS involves some degree of tissue damage and is not confined entirely to functional changes in neuromodulation
