SPATIO-TEMPORAL INFORMATION AND ANALYSIS OF LAND USE/LAND COVER CHANGES IN THE MUNI-POMADZE WETLAND

ABSTRACT Land use/land cover dynamics in wetland catchments is poorly understood; even though it is an important indicator of wetland ecological health. The study was aimed at detecting and quantifying Land Use/Land Cover (LULC) changes at the Muni-Pomadze Ramsar site in Ghana. The objective was to produce LULC maps for the area, assess the LULC dynamics during a ten year period, and establish statistical relationship between the major LULC changes and biophysical factors that influence...

MODELING POVERTY STATUS OF GHANAIANS: A LOGISTIC REGRESSION APPROACH

ABSTRACT The poor are not evenly distributed within the country and they do not share the same socio-economic and demographic characteristics. It is against this  background that analysis of the characteristics  that differentiate the poor from  the  non-poor  in  Ghana  cannot  be  underestimated.  Poverty  indicators make it possible to analyze the likely  determinants and are, therefore, essential for formulating  policy  interventions that may contribute  directly or ...

THE RELATIONSHIP BETWEEN TEACHERS’ ICT COMPETENCY AND ACADEMIC PERFORMANCE OF STUDENTS IN INFORMATION AND COMMUNICATION TECHNOLOGY IN EAST AKIM MUNICIPALITY

ABSTRACT Advances in Information and Communication Technologies (ICT’s) are changing the way people share, use, and process information . Overtime, students’ academic performance had been used to determine excellence in teacher teaching. This study was conducted to investigate the relationship between teachers’ICT competency and students’ performance in ICT in East Akim Municipality in the Eastern Region of Ghana. It also  sought to  find  out  whether availability of ICT  r...

Investigation into Iodine Deficiency of Selected Populations within Cape Coast Metropolis and Agona West Municipality in the Central Region of Ghana –Analysis of Iodised Edible Salts and Ur

ABSTRACT The iodine status of staff and pupils of Hillcrest Schools, undergraduates  of UCC, 2016/2017 academic year and a household in  Agona  Swedru  were determined  using Titration Method, Sandell-Kolthoff  Method and a  Novel Method. Discriminant analysis results showed that the Novel Method correctly classified  77.4%  of  the  original  cases.  The  novel  also  had  a  percentage recovery  of125%  and  a  Horwitz  Ratio  of  0.12.  Based  on  these, ...

LEAST SQUARES OPTIMIZATION WITH L 1-NORM REGULARIZATION

ABSTRACT The non-differentiable L1-norm penalty in the L1-norm regularized least squares problem poses a major challenge to obtaining an analytic solution. The study thus explores smoothing and non-smoothing approximations that yields differentiable loss functional that ensures a close-form solution in over-determined systems. Three smoothing approximations to the L1-norm penalty have been examined. These include the Quadratic, Sigmoid and Cubic Hermite. Tikhonov regularization is then a...

THE USE OF THE MOBILE PHONE TECHNOLOGY AS AN INSTRUCTIONAL TOOL FOR LESSON DELIVERY IN ABURA ASEBU KWAMANKESE DISTRICT

ABSTRACT  Technology has evolved over the years from being simple machines to complex ones which are making work easier and faster than usual. Despite the influx of the mobile technology with its functions into the Ghanaian society with about 38,305,078 (CIA Report, 2017), most people are still stuck to its voice and  other  basic functionalities  neglecting  the  economic  and  productivity enhancement ones. It was for these reasons that this study was carried out to find out t...

OCCURRENCE LEVELS OF HEAVY METALS IN FERMENTED COCOA BEANS AND COCOA DERIVED PRODUCTS PRODUCED IN GHANA

ABSTRACT  Cocoa is the mainstay of the economy of Ghana as it contributes about 28% of foreign exchange earnings. In recent times, cocoa has come under scrutiny because of high levels of heavy metals which are generally considered toxic. Due to the toxicity of these metals, there have been several agitations to reduce their levels as much as possible in foods; thus the setting up of stringent standards in several countries which in most cases are not supported by any scientific basis. T...

FACTORS INFLUENCING THE RANGE SHIFT OF PLANT SPECIES IN WETLANDS IN NORTHERN REGION (GHANA), WITH A NOTE ON THE FISH AND BIRD COMMUNITIES

ABSTRACT The  study  examined  the  role  of  anthropogenic  disturbances,  temperature, precipitation and evapotranspiration in the range shift of aquatic plants, fish and bird  communities  in  six  wetlands.  It  was  conducted  over  a  2-year  period.  The dominance  ratio  approach  was  used  to determine  the  range  shift  of  plants. Ordination  techniques  were  used  to  determine  the  influence  of  environmental factors  on  biologi...

An assessment of Information Security Awareness among employees in Higher Education Sector in Zambia: A case of Zambia’s public Universities

Abstract The use of Information and Communication Technology to collect and process large volumes of data into information has made it possible for organisations to find ways and means of making informed decisions within a short space of time. There is so much dependent on information systems to such an extent that system failure can adversely compromise the organisation’s operations. The education sector has not been left out but has instead become an information super house. The developm...

VULNERABILITY OF COCOA PRODUCTION TO CLIMATE CHANGE: A CASE OF THE WESTERN AND CENTRAL REGIONS IN GHANA

ABSTRACT This  research work  focused on the effect of climate change on cocoa yield in some  selected  cocoa  districts  in  the  Eastern,  Ashanti,  Western  and  Central Regions  of  Ghana.  For  sustainable  cocoa  production,  weather,  which  is  an uncontrollable  variable,  is  an  important  factor  whose  effect  on  cocoa  is difficult to quantify in a field environment. This research has two components; effects of climate change on  cocoa prod...

USING GEOMETER’S SKETCHPAD TO ENHANCE THE ABILITY TO LOCATE THE COORDINATES OF THE IMAGE OF A GEOMETRICAL OBJECT UNDER RIGID MOTION IN A CARTESIAN PLANE OF SENIOR HIGH SCHOOL 4 STUDENTS OF

ABSTRACT This research work was set out to see, if Geometer’s Sketchpad could be used to enhance the ability level of SHS 4 students of Osei Tutu II College in the location of the coordinate of the image of a point or geometrical object under Rigid Motion in a Cartesian plane. A non-probability sampling technique known as purposive sampling was employed to select the sample for the study. In all, 45 SHS 4 students comprising 34 girls and 11 boys were involved in the study. The main resear...

ENERGY-ECONOMIC ANALYSIS OF POWER PLANT CARBON DIOXIDE CAPTURE AND PIPELINE TRANSPORT IN TEXAS GULF COAST

ABSTRACT  The total investment cost of a pipeline network to transport carbon dioxide (CO2) from power plants for enhanced-oil-recovery (EOR) in oil fields in Texas Gulf Coast as CO2 mitigation has been estimated. The impact of the CO2capture and transport on power generation cost, including the benefits of atmospheric CO2mitigation has also been determined. 14 power plants comprising 55.7% of installed capacity in Texas Gulf Coast were selected. Geographical-information system was used ...

The Impact of Blended Learning on Students Using iBox Platform: Evidence of Adu Gyamfi Senior High School

ABSTRACT The study investigated the  impact of blended learning on students using IBOX platform.  A  blended  learning  environment  was  designed  to  provide opportunity  for  integrating  the  learning  management  system  “moodle”  with face-to-face  classroom  interaction.  Despite  the  implementation  of  blended learning, the poor student performance and outcomes persist. The purpose of this qualitative case study was to explore how teaching processes ...

ABSTRACT Ozara Ukwu and its environs (the study Area) is located within the Abakaliki Basin and the Afikpo sub Basin, respectively within the Afikpo Area. Detailed geologic mapping was carried out in other todetermine the various stratigraphic lithologic units, depositional environment, provenance, age and kerogene characterization, respectively using the basic field and laboratory procedures. Based on field observations, two lithostratigraphic units of the Ezeaku Group and Nkporo Group were ...

Design and Implementation of an Online Barcode Attendance System

ABSTRACT Attendance is very important in every student. a single absent make a big difference in performance in the school. Most students of high school are prone to absence from classes claiming that the class is boring. Others due to laziness fail to attend classes, having preference of going to computer shops or playing games while some students cannot refuse the prospect of a friend asking them out during class period. Some of these actions are not reported to parents or guardians because...
