Geographic mobility and social inequality among Peruvian university students

The purpose of this study was to explore geographic mobility among university students in Peru and to understand how mobility patterns differ by region and by demographic indicators of inequality. The ways that students may be able to move geographically in order to access quality higher education within the educational system can be a driver of equality or inequality, depending on who is able to take advantage. Using data from a university census, we examine how demographic indicators of inequality are related to geographic mobility for university attendance, how prior geographic mobility predicts later mobility for university attendance, and how these relationships differ based on the number and quality of universities in a region. Results show that sociodemographic variables related to social inequality explain a substantial amount of students\u27 postsecondary mobility. However, some of these relationships do not operate in the same way in all of the regions. Depending on the availability of universities and their quality, patterns of association between inequality and geographic mobility change. Implications for higher education policy as well as further research examining geographic mobility and inequality in education are discussed

Visualization and Movement as Configurations of Human-Nonhuman Engagements : Precolonial Geometric Earthwork Landscapes of the Upper Purus, Brazil

Producing geometric designs and images on materials, such as pottery, basketry, and bead artwork, as well as the human body, is elemental and widespread among Amazonian Indigenous peoples. In this article, we examine the different geometric forms identified in the precolonial geoglyph architecture of southwestern Amazonia in the context of geometric design making and relational ontologies. Our aim is to explore earthwork iconography through the lens of Amerindian visual arts and movement. Combining ethnographic and archaeological data from the Upper Purus, Brazil, the article shows how ancient history and socio-cosmology are deeply "written" onto the landscape in the form of geometric earthworks carved out of the soil, which materialize interactions between nonhuman and human actors. We underline skills in visualization, imaginative practices, and movement as ways to promote well-balanced engagements with animated life forms. Here, iconography inserted in the landscape is both a form of writing and also emerges as an agent, affecting people through visual and corporal practices.Peer reviewe

Antibacterial Activity and Composition of the Essential Oil of Peperomia galioides HBK (Piperaceae) from Peru

The essential oil from aerial parts of Peperomia galioides, a plant used in traditional Peruvian medicine, was obtained in a 0.25% yield by hydrodistillation. Globulol (22.2%), caryophyllene (10.2%) and limonene (9.8%) were found to be the major components. The oil was assayed for its in vitro activity against Gram (+) and Gram (-) bacterial strains, the results showed a moderate antibacterial activity and confirming the traditional uses of Peperomia sp
