Indigenous coping strategies could cause potential risks on hydrology, soil degradation, Biodiversity and crop yields, which would influence food safety in Kenya. However there’s little information on assessing these strategies and their impact across the four Agro-ecological Zones in Kaloleni County. The main objective of this study was to assess the climate change adaptation and mitigation strategies used by communities in Kaloleni County with an aim of identifying the most suitable...

Seventeen years after the acceptance of a new Constitution there is still no progress in implementing a language-in-education policy (LiEP) in South Africa. Systemic research shows that the literacy and numeracy skills of South African learners are far below what is required to learn and develop effectively – mainly because the government still believes that the acquisition of basic knowledge is synonymous with learning English as language of instruction. The problem starts in the Foundation...

After 1994, the post-apartheid government decided that primary health care and the district health system would be the cornerstone of their new health policy. As a consequence of this, the academic departments of Family Medicine and primary care recognised the need for a nationally agreed set of training outcomes that were more aligned with these new priorities within the public sector.

While some social scientists have appreciated the interactions between genetic and cultural evolution, the genetical evolution of behavior and the cultural evolution of human societies have been, for the most part, treated as distinct fields of inquiry. In their recent book Genes, Mind, and Culture, Charles Lumsden and E. O. Wilson argue that genetic and cultural evolution are tightly coupled one to another. The basic premise of Lumsden and Wilson's argument is both simple and compelling. An...

Long chain (C21 to C37) n-alkanes are among the most long-lived and widely utilized terrestrial plant biomarkers. Dozens of studies have examined the range and variation of n-alkane chain-length abundances in modern plants from around the world, and n-alkane distributions have been used for a variety of purposes in paleoclimatology and paleoecology as well as chemotaxonomy. However, most of the paleoecological applications of n-alkane distributions have been based on a narrow set of modern...

Thispaper is an off-shoot from class discussion on the issue of poor reading ability and habit of primary school pupils. This discussion was in a course titled School InformationSystems and Services taken by undergraduate students of Library and InformationScience, Ahmadu Bello University, Zaria. Two sets of students were used for thisstudy. Fifty (50) students from the regular programme and seventy (70) from the part-timeprogramme who are mostly teachers in their various schools were used...

Zimbabwe Open University has been in existence for over a decade and is the only institution offering open and distance learning in Zimbabwe. The institution when it started had the highest enrolment which was higher than four conventional state universities combined. Currently the university is on the enrolment decline. This is contrary to the fact that distance education is spreading to almost all areas of education and training worldwide. It is also against the background that the...

The teaching of pronunciation in Junior Secondary School in Nigeria has not received the attention it deserves. This is due to a number of factors ranging from inexperienced teachers to adoption of inappropriate techniques as well as unavailability of education media such as audio-visual materials. This situation is compounded by the simultaneous co-existence of native-speaker and non-native speaker varieties of English which has made the choice of a model to teach a difficulty. However, in...

The purpose of the research is to identify the determinants of students’ acceptance of online learning and to investigate how these determinants can shape students’ intention to use online learning. A conceptual framework based on the Technology Acceptance Model (TAM) was modified. A questionnaire was developed and used to solicit information from the 153 undergraduate students who used online learning in DBMU. The results reveal that students’ perception of ease of use, usefulness,...

Building codes did not include requirements for special seismic detailing of reinforced concrete structures until the 1970's when several earthquakes demonstrated the need for more ductile design. These buildings are vulnerable to numerous failure modes including: failure of column lap splices; strong beam/weak column failures; captive column failure; punching shear failures in flat plate slabs; and shear and axial load failure of columns with wide transverse reinforcement spacing. A...

Using SPOT-VEGETATION Normal Difference Vegetation Index (SPOT/NDVI) data from 1998 to 2011 and climate data obtained from 223 weather stations in or near North China, vegetation variation characteristics within North China were analyzed. Vegetation variation characteristics under the influence of climate variations and human activities were distinguished through a residual analysis. Based on the results of that analysis, the relative roles of climate variations and human activities in...

Africa is commonly seen as a continent of rampant political corruption, poverty, violence, and ethnic conflicts rising at times to genocide. There is some truth in this view although the real picture is diverse, with the situation varying considerably from country to country. However, the more important question seldom asked is: What are the causes of this situation? The frequent assumption is that the causes relate to internal factors that have something to do with the African people and...
