Abstract

There has been a rapid development of Information and communication Technologies (ICTs) globally, and this includes the Geographic Information Systems (GISs) which has evolved over the years and aimed at solving many geographic problems as fast and efficiently as possible. The importance of GIS to students and lecturers in higher educational institutions is it’s ability to easily analyse locations together with the conventional database systems. This paper assessed the correlation between the availability and use of GIS in Higher Educational Institutions (HEIs). The study is exploratory in nature and employed the use of questionnaires as instrument to collect data. Simple random sampling technique was used to select one hundred and ten (110) lecturers one thousand five hundred and seventy-nine (1579) students from a university. Findings revealed that GIS for analysis is still at its lowest ebb and hence calls for an action to motivate or encourage lecturers and students to use it. Though there are indications that GIS will be of great value in schools, students and lecturers they will be happy to use it for their teaching and learning. The study also revealed availability of GIS was not tied to its usage.

Abstract

The aim of this study is to investigate the challenges of implementing Big Data Technology (BDT) in Higher Educational Institutions (HEIs) in Namibia. The study further undertook quantitative surveys with staff of the three (3) higher institutions in Namibia. A sample of 345 participants from International University of Management (IUM), Namibia University of Science and Technology (NUST), and The University of Namibia comprising the study's population (UNAM) were selected for this study using the simple random sampling technique. The data collected was analysed for descriptive statistics using the Statistical Package for Social Sciences (SPSS). The finding indicated that there are challenges such as lack of awareness of BDT, lack of support for management and inadequate IT infrastructure. The study further recommended strategy that will enhance the implementation of BDT in HEIs.

Abstract

There has been a rapid development of Information and Communication Technologies (ICTs) globally, and ICT have been used as a tool to attain environment sustainability all over the world. There are diverse environmental challenges faced by developing countries such as ecosystem deterioration, pollution, resource depletion, loss of biodiversity and climate change and the management of above problems is difficult because they involve multiple actors and its occurrence is over time and space. Environmental Scientists have raised concerns on how these environmental challenges can be tackled bringing into lamplight, how ICT and environmental science research can be used to wedge these challenges in developing countries. The study is exploratory and employed the use of survey questionnaires as an instrument to collect data. Findings revealed that a lot needs to be done for ICT to be effectively used in the environment, factors such as inadequate facilities, problem of acceptance and adaptation of technology, lack of awareness and illiteracy, mismanagement, lack of technical know-how and unstable internet service are challenges that should be looked at to leverage ICT in the environment. The study also noted the fact that ICT has affected the society and its environments in other negative ways such as the production of unwanted by-products called pollution and depletion of natural resources.

Abstract

The aim of this study is to develop a framework for the use of Big Data Technology in Higher Educational Institutions (HEIs). The research which employed a mixed method approach, is primarily based on relevant critical analysis and literature review of studies conducted within the Big Data Technology area in higher education institutions. It investigated the processes of monitoring student performance by Namibian HEIs. The challenges faced by Namibian HEIs on the use of BDT. The various methods of data collection by Namibian HEIs and determined the level of readiness to adopt BDT.in Namibian HEIs. The study further undertook quantitative surveys and qualitative interviews with staff of the three (3) higher institutions in Namibia. A sample of 345 participants from International University of Management (IUM), Namibia University of Science and Technology (NUST), and The University of Namibia comprising the study's population (UNAM) were selected for this study using the simple random sampling technique. The Unified Theory of Acceptance and Use of Technology (UTAUT) constructs model was used to analyse to collect and analyse the quantitative data collected in this study. Finally, the study developed a sustainable framework that will guide the use of Big Data Technology in Namibian Higher Educational Institutions (HEIs). The validity of the framework was ascertained by expert reviews to ensure that the framework developed is effective and appropriate in fulfilling the purpose of the study and its objectives.
