Objective. To examine the relationship between family structure and the prevalence of exclusive breastfeeding (EBF) in Nicaragua. Material and Methods. A subset of the Nicaraguan Demographic and Health Survey conducted in 1998 was obtained by selecting all last-born infants less…

Obtaining an implementation of a data warehouse is a complex task that forces designers to acquire wide knowledge of the domain, thus requiring a high level of expertise and becoming it a prone-to-fail task. Based on our experience, we have…

Mainstream accounting historians study accounting in terms of its progressive development of instrumental techniques and practices, this being counterpoised to critical accounting that sees the world as
socially constructed, and intrinsically linked to organisational, social
and political contexts. This is…

The energy-loss straggling of zirconia (ZrO2) and alumina (Al2O3) has been experimentally determined for proton and alpha-particle beams mainly by means of the Rutherford backscattering technique and in some few cases using the transmission method. The incident energies of the…

This article describes the adaptation and validation of the Distance Education Learning Environments Survey (DELES) for use in investigating the qualities found in distance and hybrid education psycho-social learning environments in Spain. As Europe moves toward post-secondary student mobility, equanimity…

The work of Colombian artist Doris Salcedo has become an important reference when talking about art and its representation of violence and exclusion. Following a tradition stemming from the artistic movements of the twentieth century, Salcedo has been acknowledged as…

Critical accounting sees the world as socially constructed and intrinsically linked to organisational, social
and political contexts. Whereas mainstream accounting historians study accounting history in terms of
the progressive development of modern techniques and practices, a Foucauldian analysis challenges the

Biotechnology research is traditionally focused on individual microbial strains that are perceived to have the necessary metabolic functions, or the capability to have these functions introduced, to achieve a particular task. For many important applications, the development of such omnipotent…

We have calculated the inelastic mean free path, stopping power, and energy-loss straggling of swift electron, proton, and α-particle beams in a broad incident energy range in four organic polymers: poly(methyl methacrylate) (PMMA), Kapton, polyacetylene (PA), and poly(2-vinylpyridine) (P2VP). These…
