Trachyte plugs from the Natash volcanic field have been precisely dated using in situ U-Pb geochronology on zircon grains at ~93 Ma. Available zircon ages thus suggest that the overall volcanic history at Natash was probably shorter than previously estimated based on Rb-Sr and K-Ar ages, which are more sensitive to element mobility. Basaltic flows and trachyte plugs were produced by a largely synchronous, Upper Cretaceous volcanic activity that occurred in the Natash area at the onset of the...

The purpose of this study was to examine parent’s perception about girls’ education and to identify girls’ to boys’ dropout rate ratios of students in Weyra Boshera and Weyra Lalo primary schools of Hadiya Zone. A total of 130 households were selected using systematic random sampling technique from two selected kebeles (smallest administrative organs). Simple descriptive statistics such as frequency, percentage, and ratios were used to analyze the collected data. The findings indicated that...

The wellbeing of sexual and gender minorities (SGM) is undermined by widespread homophobia that extends to health systems, and is exacerbated by medical curricula underrepresenting the health needs of this key population group. In 2012, under the auspices of the Department of Obstetrics and Gynaecology at the University of Cape Town in South Africa, a student-inspired curriculum intervention led to the introduction of interactive participatory workshops centred on the health needs of SGM....

The primary objective of the educational process is the development of the thinking of learners. This paper deals with the development of learners' thinking in mathematics, in the transition from the acquisition of calculation algorithms to the acquisition of the algorithmic rules. Algorithmic rules need to be understood and it means the need to change the way of teaching. A substantial change in teaching is the use of question-answer system. This system is described in the paper in terms of...

Abstract We present results from a large-scale randomized experiment across 350 schools in Tanzania that studied the impact of providing schools with (i) unconditional grants, (ii) teacher incentives based on student performance, and (iii) both of the above. After two years, we find (i) no impact on student test scores from providing school grants, (ii) some evidence of positive effects from teacher incentives, and (iii) significant positive effects from providing both programs. Most...

This article illustrates the impact of potential future climate scenarios on water quantity in time and space for an East African floodplain catchment surrounded by mountainous areas. In East Africa, agricultural intensification is shifting from upland cultivation into the wetlands due to year-round water availability and fertile soils. These advantageous agricultural conditions might be hampered through climate change impacts. Additionally, water-related risks, like droughts and flooding...

The United Nations Convention on the Rights of Persons with Disabilities requires state parties to make deliberate laws, policies and administrative measures to safeguard the right to work of persons with disabilities. However, many countries, such as Ghana, run afoul of this requirement. Currently, there are intense campaigns in Ghana aimed at prioritising the education of persons with disabilities so as to enable them to explore their potential. Moreover, universities have demonstrated...

Empirical evidence is lacking on the nexus between coffee commodity output, climate change and commodity price volatility of Africa’s most populous country, Nigeria and other developing countries. To fill this gap, this study analyzed the reaction of coffee output to climate change and commodity price volatility. We used secondary data from 1961 to 2015 from reliable sources for Nigeria. The study adopted GARCH, ARCH and FMOLS in analysis of coffee output reaction to climate change...

Background: Early childhood education is essential in bridging home and school literacy practices; however, recognising the home as a literacy space remains a challenge to educators in South African schools. Aim: The aim of this article was to explore children’s literacy practices, often through play, and the potential implications this might hold for their future careers as readers and writers. The article conceptualises home as the primary domain where literacy develops. Setting: The study...

Schistosomiasis is among the most widespread chronic infections in the world. The magnitude of the infection may show variations across different areas with respect to time. Praziquantel is a first line drug of choice for the treatment of schistosomiasis although its low cure rate has been reported in different parts of the world. Thus, an assessment of the magnitude of the diseases, the efficacy of currently available drugs, and reinfection rates is crucial.Our principal objective is to...

Abstract Using data from the Living Standards Measurement Study in Malawi, we examine the spillover effects of tobacco farms on children's labor supply, education, and health. To address potential endogeneity, the share of tobacco farms in a community is instrumented by the change in tobacco buyers following termination of the intermediate buyer system. We find that, as tobacco cultivation is labor‐intensive, children in communities with more tobacco growers spend more time as casual...

To address potential endogeneity, the share of tobacco farms in a community is instrumented by the change in tobacco buyers following termination of the intermediate buyer system. We find that, as tobacco cultivation is labor-intensive, children in communities with more tobacco growers spend more time as casual laborers and are...

The study sought to investigate whether customer training in new product release will have an effect on customer loyalty.In this paper, we identify a wide-spread problem that confronts most bank customers through interviews and interactions with regards to using newly released products of the banks in Ghana.We sampled sixteen banks out of the thirty banks in Ghana using simple stratification and used simple random sampling to select 278 customers from the selected banks.Also, we interviewed...

Globally, addressing poverty levels and inequality remained one of the topmost priorities and has been accorded the first position in the Sustainable Development Goals (SDGs). Although Ghana as a whole is faring well in poverty reduction over the past decades, poverty levels and inequalities remains high in the northern parts. This study analysed the gendered welfare gap and the effects of climate change and livelihood diversification on the welfare gap. Through multistage sampling, 432...
