This paper aims to provide a broad view of the Turkana tribe of the Ilemi Triangle in northwestern Kenya, especially regarding the way the members of this nomadic ethnic group understand and shape their own construct of health and disease. It is based in an ethnographic study carried out in July and August 2014, including participant observation of 15 villages of the Turkana tribe, formal inter...

The family Gymnophthalmidae contains nearly 235 species with a distribution range from southern Mexico to central Argentina as well as in the Antilles. Among gymnophthalmids, the genus Colobosaura is a member of the tribe Iphisini, and currently is considered monotypic (C. modesta). The diversity of the tribe was studied recently, with the erection of several new genera. In this work genetic an...

Suicide rates among Indian youth in the United States are two to three times the national average. Although researchers have identified related risk and protective factors, they have limited understanding of the perspectives of youth at risk. In this descriptive, ethnographic study in a Pacific Northwest tribe, the goal was to gain an understanding of the life experiences of the youth. Focus gr...

The tribe Acacieae (Fabaceae: Mimosoideae) contains two genera, the monotypic African Faidherbia and the pantropical Acacia, which comprise about 1200 species with over 950 confined to Australia. As currently recognized, the genus Acacia is subdivided into three subgenera: subg. Acacia, subg. Aculeiferum, and the predominantly Australian subg. Phyllodineae. Morphological studies have suggested ...

Pseudorandom function tribe ensembles are pseudorandom function ensembles that have an additional collision resistance property: almost all functions have disjoint ranges. We present an alternative to the construction of pseudorandom function tribe ensembles based on oneway permutations given by Canetti, Micciancio and Reingold [7]. Our approach yields two different but related solutions: One c...

Endemic Burkitt's lymphoma (BL) is the most common paediatric malignancy in equatorial Africa and was originally shown to occur at high-incidence rates in regions where malaria transmission is holoendemic. New ecological models of malaria that are based on both parasite prevalence and disease have been described. In this study, we examined district level data collected from paediatric BL cases ...

The Ticuna are an Amerindian tribe of Central Amazonas, a key location in theories of the peopling of eastern South America. The results of typing some 1760 members of the tribe with respect to 37 different genetic systems are reported, as are the results of HLA typings on a subsample of 129 persons. Salient findings include the following. (1) Except for a high frequency of LMs allele and an un...

BACKGROUND AND AIMS The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, the staminal morphology of the...

Anthidiini comprise a large, diversified, and widely distributed tribe of megachiline bees. Recently, morphological molecular analyses recovered five major monophyletic groups within the tribe. For this reason, we review current classification tribe, giving status subtribe to these lineages. A new subtribe, Epanthidiina (type genus: Epanthidium Moure), is proposed for large group restricted Neo...
