The Department of Economics has one of the highest rates of students’ failures, repetition and withdrawals in the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. In the 2011/2012 and 2012/2013 academic years 35.8% and 30.6% of the 232 and 301 final year students respectively could not graduate. This concern has been attributed primarily to the low mathematical ability of the...

Porous titanium carbide (TiC) and TiC/Ti composites were synthesized by self-propagating high-temperature synthesis (SHS). Titanium and carbon powders were blended by various Ti/C blending ratios. The heat of reaction between titanium and carbon was high enough to induce the self-sustaining reaction of TiC formation on condition that some processing parameters (Ti/C ratio and porosity of the pr...

Due to serious environmental problem and strict regulations to control pollution, researchers across the globe are putting their effort to find clean, renewable, greener and cost effective method to produce biochemical from biomass. The aim of this article was to highlight the method to extract phenolic compounds from crude pyrolysis oil using switchable hydrophilicity solvents (SHS). The pyrol...

This document describes the working environment developed by ESCoM laboratory (Equipe Sémiotique Cognitive et Nouveaux Médias, Fondation Maison des Sciences de l’Homme) during the ASA-SHS project (Audiovisual Semiotic Workshop for Human and Social Sciences). ASA-SHS is a R&D project financed by the French National Research Agency (ANR, Programme Blanc 2008) and targets to develop strategies of ...

Aim: To explore the experiences of self-reported health (SRH) of 6-year-old boys and girls. Background: The goals for the Swedish School Health Services (SHS) are to identify health problems, take measures to prevent illness, and promote health. One approach used to achieve this is the use of the Health Dialogue (HD) questionnaire. The HD is offered at three occasions during compulsory school a...

A new, general strategy for the synthesis of biologically active multivalent arrays displaying diverse functionality has been developed. This method exploits the ability of ring-opening metathesis polymerizations to produce polymers of defined lengths. By incorporating N-hydroxysuccinimide esters into the polymers, recognition epitopes bearing nucleophilic functional groups, in this case an R-m...

Our work is in the field of the validation of term candidates occurrences in context. The textual data used in this article comes from the freely available corpus SCIENTEXT. The term candidates are computed by the platform TTC-TermSuite and their occurrences are projected in the texts. The main issue of this article is to examine how contexts are able to provide relevant linguistic criteria to ...

Background Despite a multitude of anti-smoking campaigns being active worldwide, the number of smokers is currently larger than at any other time in human history. An essential first step towards minimizing the health effects of secondhand smoke (SHS) is to accurately assess the exposure level of individuals. The objectives of this study were to: (i) to develop questionnaires that can identify ...

The study identified and evaluated the options for population-level government policies to increase the prevalence of homes free of secondhand smoke (SHS). We used three criteria to evaluate the policy options: effectiveness, the reductions on inequalities in SHS exposure, and cost-effectiveness. Evidence indicates some association between relatively comprehensive tobacco control programmes and...

The present study aims to analyze the psychometric properties of the Subjective Happiness Scale on a Romanian adult sample. The Romanian version of the SHS had excellent psychometric properties. All items loaded in the expected factor, being a unidimensional scale. The confirmatory factor analysis results revealed excellent fit indices. Convergent validity showed high associations with satisfac...
