TL;DR: In this article, multiple regression analyses were conducted on the 2011 Trends in International Mathematics and Science Study (TIMSS) data to determine the resources factors that influence South African learners' performance in mathematics.
Abstract: The creation of an environment conducive to learning is vitally important in the academic achievement of learners. Such an environment extends beyond the classroom and school to include the home. It is from these environments that learners draw resources, both tangible and intangible, that impact on their educational experience. While current bodies of literature focus on either school or home resources, this paper looks at both. Multiple regression analyses were conducted on the 2011 Trends in International Mathematics and Science Study (TIMSS) data to determine the resources factors that influence South African learners’ performance in mathematics. The findings reveal that both school and home environments play significant roles in learners’ mathematics performance. This paper therefore suggests that it is not only the socio-economic factors of schools that impact learners’ mathematics performance, but also that higher levels of parental education have a significant positive influence. Keywords : home resources; learning environment; mathematics performance; predictors of performance; school resources; TIMSS 2011

TL;DR: In this paper, the authors examined the inter-temporal causal relationship between financial sector development and poverty reduction in Zambia, using the newly developed autoregressive distributed lag-bounds testing procedure, which has numerous advantages, especially when the sample size is small.
Abstract: Purpose – The purpose of this paper is to examine the inter‐temporal causal relationship between financial sector development and poverty reduction in Zambia. The paper attempts to answer one critical question: does financial sector development in Zambia lead to poverty reduction?Design/methodology/approach – The paper uses the newly developed autoregressive distributed lag‐bounds testing procedure, which has numerous advantages, especially when the sample size is small. In addition, the paper uses three proxies of financial development, namely broad money supply (M2/GDP), domestic credit to the private sector as a ratio of gross domestic product (DCP/GDP) and domestic money bank assets (DMBA), against private per capita consumption, a proxy for poverty reduction.Findings – When the broad money supply ratio (M2/GDP) is used as a proxy for financial sector development, poverty reduction seems to cause the development of the financial sector. However, when the DCP and the DMBA are used, financial developmen...

TL;DR: In this article, a template-free method for reductive degradation and removal of Congo red (CR) from aqueous solutions was described. And the PANI/Fe 0 CNFs were prepared via rapid mixing polymerization of aniline monomers with Fe(III) chloride as an oxidant, followed by reduction of polymerization by products (Fe(II)/Fe(III)) as the Fe precursor.

TL;DR: It is demonstrated that an electric field of ~200 V/μm is able to extract current from the flat part of MoS2 bilayers, which can therefore be conveniently exploited for field emission applications even in low field enhancement configurations.
