Mineral transformations in soils are important processes in assessing pedogenesis. A micromorphological study, complemented by mineralogical and physicochemical analyses, was conducted for two contrasting soils developed on tephra of Mt. Manengouba, i.e. an Andosol and a Cambisol, in order to compare weathering trends based on olivine and biotite alteration. The contrasting character of the two soils is portrayed in their various properties, and is also observed in the field. The majority of...

Higher education in the twenty-first century has gradually transformed from being an elite phenomenon to one that is now accessible by the masses. This has changed the profile of universities from being “ivory tower” institutions to instead being mostly within reach by far more people than ever before. In addition to its intellectual and educational functions of teaching and research, higher education’s responsibility to the public needs to be more clearly defined in order to adequately...

Using a unique dataset from three Sub-Saharan African countries, we investigate how learning-by-exporting varies across firm age. Assuming a Cobb-Douglas production technology, we use propensity score matching methods to match exporters (treated) and non-exporters (control) to test for learning-by-exporting effects across firm age. Our findings reveal that new exporters are different from non-exporters. We find high productivity growth rates among younger firms than older firms. However,...

The Intergovernmental Panel on Climate Change is clear on the fact that ‘Africa is one of the most vulnerable continents to climate variability and change.’ True to this fact, Nigeria, whose oil and gas industry contributes massively to the global rise of greenhouse gas emissions through gas flaring, is experiencing the adverse effects of climate change in term of increasing cases of droughts, floods, amongst others. Considering the potential contributions which a national court can make in...

Africa is vulnerable to the effects of climate change. While some African states have contributed very little to the global greenhouse gas (GHG) emissions driving climate change, others are heavier polluters. Over many decades, Nigeria’s oil and gas industry and the gas flaring for which it is notorious, has significantly contributed to the global rise of GHGs. The country is already experiencing the adverse effects of climate change in term of increasing cases of droughts, sea-level rise,...

Students need supportive, empowering and enabling technology-driven environment to make learning interesting and retentive.

Abstract As a Small Island Developing State (SIDS), Seychelles is quite vulnerable to the impacts of climate change, and adaptation is considered a national priority. Despite efforts to enhance its adaptive capacity, a number of barriers still hamper the adaptation process such as fragile institutions and inadequate governance to climate change, financial and human resource capacity constraints, and limited scientific knowledge and understanding of how climate change affects the country. A...

The premise that theory informs practice guides training and educational programs. Teacher education programs impart knowledge and skills (theory) which are meant for use during teaching and learning, thereby putting theory into practice. There seems to be inconsistency between theory as taught at college and the practices by teachers in Zimbabwean schools. Teachers use theory at a rather superficial level as they tend to forget the theory for various reasons. As a result, there is the need...
