High adult mortality among Hiwi hunter-gatherers: Implications for human evolution

Journal of Human Evolution, 2007
Extant apes experience early sexual maturity and short life spans relative to modern humans. Both of these traits and others are linked by life-history theory to mortality rates experienced at different ages by our hominin ancestors. However, currently there is a great deal of debate concerning hominin mortality profiles at different periods of ...

Overexpression of Hiwi Inhibits the Cell Growth of Chronic Myeloid Leukemia K562 Cells and Enhances Their Chemosensitivity to Daunomycin

Cell Biochemistry and Biophysics, 2015
Chronic myeloid leukemia (CML) is a clonal disorder characterized by excessive accumulation of myeloid cells in the peripheral blood. In the present study, to investigate the role of Hiwi in leukemogenesis, lentivirus-mediated Hiwi overexpression was performed in a CML cell line, K562 cells.

HiWi Project: High Efficiency Electric Drives

2015
Vehicles develop their highest efficiency of around 93–95 % within a speed range of usually 1/4 to 1/3 of the maximum, whereas in real-life driving cycles the motor operates at a wider range of speeds and at partial load, resulting in much lower efficiency.

Food Transfers Among Hiwi Foragers of Venezuela: Tests of Reciprocity

Human Ecology, 2000
Although food sharing has been observed in many traditional societies, we still do not have a deep understanding of how various ecological conditions produce variation in who gives and who receives specific resources. To understand better the behavioral ecology of food sharing, we present data collected with the Hiwi of Venezuela and focus on two ...

The role Hiwi gene in the maintenance of lung cancer stem cell populations

Neoplasma, 2013
The Piwi family genes are highly conserved during evolution and play essential roles in stem cell self-renewal in diverse organisms. However, data on the function of Hiwi gene (a human homologue of Piwi family) in cancer stem cells remains obscure. The aim of this study was to investigate the role of Hiwi gene in the lung cancer stem cells.

Early dry season subsistence ecology of Cuiva (Hiwi) foragers of Venezuela

Human Ecology, 1987
The subsistence ecology of Venezuelan Cuiva foragers during the early dry season is described. Data on diet, time allocation, demography, and physical measurements are presented. Analyses show that the Cuiva depend primarily on game and wild roots during the early dry season for their subsistence.

Trade-Offs between female food acquisition and child care among hiwi and ache foragers

Human Nature, 1992
Even though female food acquisition is an area of considerable interest in hunter-gatherer research, the ecological determinants of women's economic decisions in these populations are still poorly understood. The literature on female foraging behavior indicates that there is considerable variation within and across foraging societies in the amount of ...
