Background Comparing self-rating health responses across individuals and cultures is misleading due to different reporting behaviors. Anchoring vignettes is a technique that allows identifying and adjusting self-rating responses for reporting heterogeneity (RH). Objective This article aims to test two crucial assumptions of vignette equivalence (VE) and response consistency (RC) that are requir...

It is estimated globally 3.2 million children were living with HIV in 2014, that mostly in sub-Saharan Africa. However, the majority of them infected to HIV from their mothers during pregnancy, during delivery or breastfeeding (1). Antiretroviral therapy (ART) use during and after pregnancy is essential for prevention of mother-to-child transmission (PMTCT) of HIV (2).  In the absence of any in...

Vegetation productivity is an essential variable in ecosystem functioning. Vegetation dynamics of dryland ecosystems are most strongly determined by water availability and consequently by rainfall and there is a need to better understand how water limited ecosystems respond to altered rainfall amounts and variability. This response is partly determined by the vegetation functional response to r...

● More than 1 in 5 architects was self-employed—about three times the proportion for all professional and related occupations. ● Licensing requirements include a professional degree in architecture, a period of practical training, and passing all divisions of the Architect Registration Examination. ● Architecture graduates may face competition, especially for jobs in the most prestigious firms;...

In many point-line geometries, to cover all points except one, more lines are needed than to cover all points. Bounds can be given by looking at the dimension of the space of functions induced by polynomials of bounded degree.

This study has used TOMS AI as well as the reanalysis dataset of thirty-four years (1979-2012) to investigate the influence of atmospheric circulation on dust transport during the Harmattan period in West Africa, using Aerosol Index (AI) data, obtained from various satellite sensors. Changes in Inter-Tropical Discontinuity (ITD), Sea Surface Temperature (SST) over the Gulf of Guinea, and North ...
