Analysis of Factors for the Uncorrelated Relationship between the Broadband Internet Initiatives against Broadband Adoption for Rural Areas in Low and Middle-Income Countries: A Case of Tanzania
Get PDFAs evident as the contribution of broadband internet in developed countries’ economies has been, many developing countries have taken initiatives to exploit the same. However, the efforts are not reflected in the rural areas broadband adoption as reported by global Information and Communication Technologies (ICTs’) ranking bodies. This study aims to analyze the factors towards the uncorrelated relationship between the broadband initiatives against broadband adoption in rural parts of Low Middle-Income Countries (LMICs) looking from the supply side, exemplified here by Tanzania. The initiatives considered are National ICT Broadband Backbone (NICTBB) and Universal Communication Service Access Fund (UCSAF). The study deployed a Qualitative Research Method (QRM) exploiting semi-structured interviews for data collection. 23 interviews were conducted with personnel from the aforementioned entities together with their collaborating agencies. Thematic analysis was opted where vigorous coding and data cleaning resulted in five themes characterizing poor broadband adoption; infrastructure, affordability, digital skills, contents’ relevance and services, and statistical reporting. The majority of the response (84%) agreed that the ranks reflect what is found on the ground hence more work is needed from the supply side on enforcing adoption in rural areas. Nevertheless, 16% of the coded responses maintain a view that improper statistical reporting due to statistical model mismatch and data unavailability from local statistical agencies to some extent causes the poor adoption ranks in the global ranking bodies. This article should provide insights to policymakers towards creating/improving and implementation of broadband plans/policies, and as a result, exploiting broadband contribution to countries’ Gross Domestic Product (GDP)

A mathematical Model to assess the Role of Neglected Control Techniques in the Dynamics of Banana Xanthomonas Wilt Disease
Get PDFBanana Xanthomonas Wilt disease (BXW) is a destructive bacterial disease that highly threatens banana production in East and Central Africa. It is caused by a bacteria known as. In this paper, a mathematical model for the dynamics and control of BXW disease is formulated and analyzed. Numerical simulations were performed to examine the impact of participatory community education programs, clearance of Xcm bacteria in the soil, single diseased stem removal, and vertical transmission control strategies. It was found that participatory community farming education programs, timely removal of infected banana plants, clearance of Xcm bacteria in the soil dramatically reduce the number of secondary infections hence greatly contributing to the control of the BXW disease. The study recommends that, along with the existing control measures such as sterilization of farming tools, timely removal of the male bud using a forked stick and planting healthy suckers, more emphasis should be invested in educating farmers on disease detection and management strategies and increasing the rate of clearing Xcm bacteria in the soil so as to avoid persistence of the disease in the farms
Tourism SMEs usage of Social Media Analytics as their Business Intelligence Tool
Get PDFThis study delivers the results of the survey conducted to investigate the tourism SMEs' usage of social media analytics as their business intelligence tool. The study uses the unified theory of acceptance and use of technology (UTAUT) model to investigate the usage of SMA to tourism SMEs. 71 tourism SMEs were interviewed in Arusha and Kilimanjaro regions by filling the semi-structured questionnaires, then followed by the data analysis using MS excel and Python. The results of the findings show that the usage of social media analytics as a business intelligence tool for tourism SMEs is beneficial to them, however, findings show very few tourism SMEs are conducting social media analytics on their social media platforms. Most tourism SMEs use built-in social media analytics and they are performing simple metrics like counting the number of likes, comments, and shares. Further results explain that the majority of the tourism SMEs don't have more information and knowledge about social media analytics and tools used to perform social media analytics as well as they are performing social media analytics without following any implementation framework to guide the process. The study recommends that social media stakeholders increase awareness of social media analytics to tourism SMEs so that they could use it and get more advantages of using social media. Furthermore, researchers information systems analysts and developers develop social media analytics tools specifically for tourism SMEs and provide them step-by-step procedures that will help them in using and managing the social media analytics activities.

Experimental Study of effect of Powder Coating thickness and layers on Hardness and Corrosion properties of Carbon Steel Material
Get PDFPowder coating is one of the coating techniques that are widely used today as a substitute for coating using liquid painting. In this research, we report on the effect of the various layers of powder coating on the hardness and corrosion rate of the material. Three different layers of variation were observed with 1, 2, and 4 layers to obtain the best results. The cleaning process was applied before coating the samples. The coating process was performed in a special room/box to avoid contact with air and contamination from the outside environment with a spraying distance of about 20-30 cm. The morphology is compact and bigger grains are seen to be emerging in the 1 layer deposition. Many grains are visible, and uniform grains are distributed in the 2 layers deposited. For the 4 layers, due to higher layer deposition incorporation, the grain size is seen to be enlarged due to the merging of smaller grains with each other ultimately increasing the grain size. The uncoated material has a corrosion rate of 0.505 mm/year which means fair for the relative corrosion resistance. The coated samples have a corrosion rate of 0.353, 0.252, and 0.354 mm/year for the 1 layer, 2 layers, and 4 layers, respectively. Based on the calculation, the average number of the Rockwell hardness of un-coated and coated samples for the 1 layer, 2 layers, and 4 layers, respectively were estimated at about 70, 78, 79, and 58 HRB, respectively. The highest average hardness value is in sample B with 2 layers of 79 HRB. The lowest average hardness value is in sample B with 2 layers of 58 HRB. The lowest performance of sample D with 4 layers confirms the result as shown in the corrosion rate result
A review of the Development Trend of Personalized learning Technologies and its Applications
Get PDFPersonalized learning tailors material and strategy to student requirements, interests, and goals in e-learning. These developments help educational institutions and other organizations to keep up with the fast pace of information technology, communications, and computing power. Studies show that self-adaptive learning and relevant learning information improve study efficiency. Compared to traditional teaching methods, the practice of online education is well in its infancy. On the other hand, the pedagogy and evaluation of students in online courses have a large gap that has to be filled, necessitating significant improvements in e-learning. We call this approach to education "personalized learning," which is a central focus of today's leading online education platforms. Several studies have been conducted on e-learning and personalized learning, but few investigated the development trend of personalized learning technologies and applications. Therefore this study examines the literature to close the gap and promote the development trend for personalized learning technologies and applications in higher education from 2010 to 2021 by analyzing related journal articles. The pivotal studies used inclusion criteria after a search generated 372 complete research articles and reduced them to 146 publications based on their proposed learning domains and research themes. Through carefully reviewing current trends and successes in numerous aspects of personalized learning, this discussion analyzes prospective future research directions in the field of personalized learning
Geophysical and Borehole Studies for Optimum Drilling Depth and Groundwater Yields in a Typical Basement Terrain, South-western Nigeria
Get PDFThis study embraced the integration of 20 vertical electrical sounding (VES) and 15 borehole log datasets to determine optimum drilling depth and yields of boreholes in part of Akungba - Akoko, southwestern Nigeria. Resistivity soundings interpretation was aided by borehole litho-geologic information. Results revealed line-to-line correlation of three-five distinct subsurface geological/geoelectrical profiles to include; the topsoil, sandy/clayey weathered/partially weathered basement, fractured basement/ fresh basement. The thickness and resistivity of the weathered basement column ranged between 1.9 - 15.8 m and 26 - 579 ohm-m respectively. Regoliths, with a mean thickness of 9.97 m (approximately 10 m), constituted thin aquitards developed on the basement. The combination of regoliths and the near–surfaced interbedding multiple thin layers of the fractured basement up to 30 m depths gave lower yields of less than 1.0 l/s to shallow boreholes. These drilled depths were those constrained at the instance of the poor index of lithologies exhibited by the sounding results, thus rendering the thin fractured beds undifferentiated from the thick resistive basement. Depths for high groundwater yields of 1.15 – 2.56 l/s were recorded for deeper borehole depths of 46 - 70 m, with a mean of 55.3 m. It can therefore be concluded that optimum groundwater yields not less than 2.0 l/s were recorded for boreholes that took full advantage of the weathered lithology and structures at deeper depths of 60 - 65 m. The study further asserts that beyond the mean depth of 55.3 m, the deposits become more compacted, low fracture density with groundwater yields wholly retarded, thereby leaving the optimum drilling depth to 70 m, as the target of most groundwater prospects for optimum yields of deeper boreholes in the area
