Beyond the here and now: hunter-gatherer socio-spatial complexity and the evolution of language.

Human evolutionary ecology stands to benefit by integrating theory and methods developed in movement ecology, and in turn, to make contributions to the broader field of movement ecology by leveraging our species' distinct attributes. In this paper, we review data and evolutionary models suggesting that major changes in socio-spatial behaviour accompanied the evolution of language. To illustrate and explore these issues, we present a comparison of GPS measures of the socio-spatial behaviour of Hadza hunter-gatherers of northern Tanzania to those of olive baboons (), a comparatively small-brained primate that is also savanna-adapted.

A Case of Metastatic Vulvar Choriocarcinoma Misdiagnosed as Vulvar Abscess: A Case Report.

Metastatic vulvar choriocarcinoma, a rare ectopic gestational trophoblastic neoplasia (GTN), often presents a diagnostic challenge due to its mimicry of other conditions, particularly in resource-limited settings. Its primary symptom is abnormal vaginal bleeding without a clear cause. Consequently, diagnosing and managing it poses difficulties for many low-resource health facilities, as evidenced by the current case.

Spatial-structural analysis of macroeconomic factors' impact on carbon emissions in East Africa: a spatial econometric panel study.

Despite the abundance of research on reducing carbon emissions, there is a significant gap in understanding the influence of macroeconomic factors on carbon dioxide (CO) emissions from a spatial-structural perspective. This study aims to contribute to the literature by investigating the impact of macroeconomic factors on carbon dioxide emissions in six East African countries between 1989 and 2020. Using spatial econometric panel models, the study analyzed spatial dependence among the variables.

1. Morphological traits of fruits and seeds of tree species growing in different land uses in Ethiopia.

The practice of gathering and utilizing Ziziphus tree fruits serves as a key strategy to enhance nutrition and livelihoods employed by rural communities across various regions worldwide. Despite a burgeoning interest in and comprehension of their significance, there remains a dearth of information concerning the morphological attributes of both fruits and seeds essential for bolstering resistance against pests and diseases through breeding efforts. In this regard, comprehensive data pertaining to fruit dimensions (length, width, weight, and maturity level) and seed characteristics (length, width, and 100-seed weight) across three distinct land use types (LUT)-farmland (FL), home garden (HG), and roadside (RS)-were systematically gathered to ascertain the variability in traits among tree species in the Bosset and Bati districts of Ethiopia.

Evaluating the modulation of peripheral immune profile in people living with HIV and (Neuro)cysticercosis.

Background: The parasitic infection caused by Taenia solium represents a significant public health concern in developing countries. Larval invasion of body tissues leads to cysticercosis (CC), while central nervous system (CNS) involvement results in neurocysticercosis (NCC). Both conditions exhibit diverse clinical manifestations, and the potential impact of concomitant HIV infection especially prevalent in sub-Saharan Africa on peripheral and CNS immune responses remains poorly understood.

Estimation of Carleman operator from a univariate time series.

Reconstructing a nonlinear dynamical system from empirical time series is a fundamental task in data-driven analysis. One of the main challenges is the existence of hidden variables; we only have records for some variables, and those for hidden variables are unavailable. In this work, the techniques for Carleman linearization, phase-space embedding, and dynamic mode decomposition are integrated to rebuild an optimal dynamical system from time series for one specific variable.

Archival mitogenomes identify invasion by the CAPE lineage caused an African amphibian extinction in the wild.

Outbreaks of emerging infectious diseases are influenced by local biotic and abiotic factors, with host declines occurring when conditions favour the pathogen. Deterioration in the population of the micro-endemic Tanzanian Kihansi spray toad () occurred after the construction of a hydropower dam, implicating habitat modification in this species decline. Population recovery followed habitat augmentation; however, a subsequent outbreak of chytridiomycosis caused by () led to the spray toad's extinction in the wild.

Using digital technology as a platform to strengthen the continuum of care at community level for maternal, child and adolescent health in Tanzania: introducing the Afya-Tek program.

Inadequate care within Tanzania's primary health system contributes to thousands of preventable maternal and child deaths, and unwanted pregnancies each year. A key contributor is lack of coordination between three primary healthcare actors: public sector Community Health Workers (CHWs) and health facilities, and private sector Accredited Drug Dispensing Outlets (ADDOs). The Afya-Tek program aims to improve the continuity of care amongst these actors in Kibaha district, through a mobile-application based digital referral system that focuses on improving maternal, child and adolescent health.
