Title A name given to the resource An Item Response Model for Understanding Item Non-response in Ghanaian Surveys Creator An entity primarily responsible for making the resource NK Frempong, I Wahab Abdul, E Okyere Description An account of the resource Survey research has been widely used in public opinion research in Ghana. Ghanaian researchers are happy about data richness and they are also concerned about data quality. In this paper Item Response Theory (IRT) has been used to identify the most appropriate IRT model for understanding item. The techniques are appropriate and practical. A questionnaire data on Ghana collected in the 5th wave of the World Values Survey was used for the analysis. The five categories of survey questions that are most difficult to answer by respondents were Life Related Questions, Value Related Questions, Political Related Questions, Income Related Questions and Democracy Related Questions. Missing or ‘don’t know’responses were assigned a 0 score, and 1 was assigned to answered items. The data was analysed based on four IRT models namely, the constrained Rasch model, the unconstrained Rasch model, the two parameter logistic model, and the three parameter logistic model. These models were explored to determine the most appropriate model for the data. In this paper, the unconstrained Rasch model emerged as the best model for understanding item non-response. We found that, income related questions had the highest difficulty parameter, hence the most difficult category of survey questions to answer. It was also found that, if an individual does not answer a survey question or give a ‘don’t know’answer, it is not only because of the question’s difficulty but also because the respondent doesn’t want to answer.

Title A name given to the resource Application of Macrobenthic Faunal Indices in Assesssing the Ecological Quality Status of Laloi Lagoon of Ghana Creator An entity primarily responsible for making the resource Rita Esi Ampiaw, Martin Owusu Amoamah, Iddrisu Wahab Abdul, Joseph Dadzie Description An account of the resource The aim of this study was to assess the macrobenthic fauna structure and use its indices as a tool for characterizing the ecological state of the Laloi lagoon. Thus, a field assessment of the benthos in the Laloi lagoon was carried in January 2012. Four replicate samples were taken at each station contained in three zones and analysed for their structure and composition. Twenty-one (21) species of macrobenthos belonging to 19 genera were identified. The highest number of species belonged to Polychaetes (15 species) followed by Bivalves (6 species) and 1 species of Gastropod. The grain size of sediments and total organic matter as essential factors in distribution and population diversity of macrobenthos communities were also analysed. The results showed that all of the stations were characterized by medium sand to very fine sand. Shannon-Wiener index (H'), species richness (S) and Pielou’s evenness were calculated and they revealed a high species diversity with variability in abundance within stations. The ecological indices, such as (AMBI, M-AMBI, BENTIX and H’) were also applied to the available benthic species data to determine the ecological status of the lagoon. AMBI, M-AMBI, H'and BENTIX gave different results regarding the boundaries for High, Good and Moderate and it was worse when applying H'and BENTIX. However, the index AMBI provided a more suitable evaluation of EcoQS corresponding to ‘slightly polluted’lagoons in compliance with univariate community indices.

Title A name given to the resource Research Article Modelling Trends of Climatic Variability and Malaria in Ghana Using Vector Autoregression Creator An entity primarily responsible for making the resource Sylvia Ankamah, Kaku S Nokoe, Wahab A Iddrisu Description An account of the resource Malaria is considered endemic in over hundred countries across the globe. Many cases of malaria and deaths due to malaria occur in Sub-Saharan Africa. The disease is of great public health concern since it affects people of all age groups more especially pregnant women and children because of their vulnerability. This study sought to use vector autoregression (VAR) models to model the impact of climatic variability on malaria. Monthly climatic data (rainfall, maximum temperature, and relative humidity) from 2010 to 2015 were obtained from the Ghana Meteorological Agency while data on malaria for the same period were obtained from the Ghana Health Service. Results of the Granger and instantaneous causality tests led to a conclusion that malaria is influenced by all three climatic variables. The impulse response analyses indicated that the highest positive effect of maximum temperature, relative humidity, and rainfall on malaria is observed in the months of September, March, and October, respectively. The decomposition of forecast variance indicates varying degree of malaria dependence on the climatic variables, with as high as 12.65% of the variability in the trend of malaria which has been explained by past innovations in maximum temperature alone. This is quite significant and therefore, policy-makers should not ignore temperature when formulating policies to address malaria.

Title A name given to the resource Research Article Structural Model of Students’ Interest and Self-Motivation to Learning Mathematics Creator An entity primarily responsible for making the resource Dominic Otoo, Wahab A Iddrisu, Justice A Kessie, Ernest Larbi Description An account of the resource Students pick up the perception that mathematics is abstract and therefore, the learning of mathematics would yield to them no benefit. With their attitude towards mathematics modelled and their interest for mathematics impacted by this automatic generated perception, they may never again appreciate the beauty of mathematics. In this paper, the researchers used structural equation modeling (SEM), to investigate the variables that affect students’ interest, among the variables, students’ confidence and motivation. e foregoing variables were conceptualized to have a direct effect on students’ interest in mathematics, whilst mathematics anxiety and students’ knowledge of the usefulness of mathematics were conceptualized to have indirect effects on their interest in mathematics moderated by students’ confidence and motivation. e result showed that significantly students’ confidence directly affects students’ interest in the learning of mathematics and there is a direct relationship between confidence and motivation. A student’s knowledge about the usefulness of mathematics indirectly increases the student’s interest in mathematics.

Title A name given to the resource Seasonal changes in stream habitat structure and its relationship with fish community structure in a low gradient stream in Sunyani, Ghana Creator An entity primarily responsible for making the resource PO Sanful, S Amfoh, AW Iddrisu Description An account of the resource tudies on seasonal changes in stream structure and its effect on habitat quality, distribution, abundance and biomass of stream fishes in Ghana is limited. Understanding seasonal changes in stream habitat structure and adaptive responses of fish populations is essential for stream protection and conservation of stream ecosystems and their resident fish populations. Seasonal changes in stream structure, physicochemical characteristics and fish community structure were investigated in an urban stream in Sunyani, Ghana. Data was collected monthly from November 2016 to November 2017 at upstream, midstream and downstream sites. High spatial heterogeneity and temporal variability in stream structure affected by the dry and wet seasonal cycles was observed. Twelve species of fish belonging to eight families and ten genera were recorded, with catfishes dominating community biomass. The diet pattern of fish species differentiated the community into herbivore, piscivore and omnivore trophic levels. Herbivores were most abundant and consumed a wide range of plantbased food. Fish habitats disappeared and mortality increased upstream and midstream during the dry season. However, the downstream habitat persisted as a result of the unique morphology which resulted in a relatively deep depth, large canopy cover and presence of water lettuce Pistia stratiotes which minimized water loss. Water quality did not differ significantly across the stream in all seasons. Higher water clarity downstream cooccurred with Pistia proliferation along with elevated fish biomass during the dry season.

Title A name given to the resource Research Article Comparing Bayesian and Maximum Likelihood Methods in Structural Equation Modelling of University Student Satisfaction: An Empirical Analysis Creator An entity primarily responsible for making the resource Killian Asampana Asosega, Wahab Abdul Iddrisu, Kassim Tawiah, Alex Akwasi Opoku, Eric Okyere Description An account of the resource Students’ satisfaction in the university environment is essential to both the student (customer) and management of the university. Satisfied students are determined to succeed in their academics, and this sustains their loyalty and trust, which results in an improved image and esteem of the university. This study examined the level of students’ satisfaction with campus facilities and infrastructure, campus social life, student support services, and the quality of academics in the University of Energy and Natural Resources (UENR) in Ghana and further investigated how students’ satisfaction with the above four areas of the university environment affect each other. A questionnaire was administered to continuous students in UENR, and the collected data were analysed using structural equation modelling within the maximum likelihood and Bayesian frameworks whose results and performance were compared. Results showed that students’ satisfaction levels with available campus facilities, campus social life, and student support services were low but were fairly satisfied with the quality of academics. Both maximum likelihood and Bayesian techniques showed positive significant effects of students’ satisfaction with campus facilities and infrastructure on satisfaction with campus social life, students’ support services, and academics. Moreover, students’ satisfaction with social life was positively associated with their satisfaction with academics and student support services. Although both estimation methods obtained similar estimates and inferences, the Bayesian SEM outperformed the ML-SEM based on the recommended fit indices.

Title A name given to the resource The Road to a Greener Future: How Government Expenditure and Effectiveness Drive Renewal Energy Consumption Creator An entity primarily responsible for making the resource Alhassan Bunyaminu, Shani Bashiru, Wahab Abdul Iddrisu, Adibura Baba Seidu, Ahmed Jamal Iddrisu Description An account of the resource This study examines the impact of government expenditure and government effectiveness on renewable energy consumption in Africa from 1990 to 2021. Utilizing the fixed effects technique, the findings indicate a positive significant relationship between government expenditure and renewable energy consumption, while government effectiveness demonstrates a significant negative influence. Additionally, trade openness and urbanization exhibit a negative impact on renewable energy usage. The effect of foreign direct investment (FDI) on renewable energy consumption is found to be mixed. To facilitate the transition towards a greener energy future in Africa, the study recommends several measures including increasing government expenditure on renewable energy, enhancing government effectiveness, promoting sustainable trade practices, and prioritizing sustainable urban planning.

Title A name given to the resource Research Article Modeling Cholera Epidemiology Using Stochastic Differential Equations Creator An entity primarily responsible for making the resource Wahab A Iddrisu, Inusah Iddrisu, Abdul-Karim Iddrisu Description An account of the resource In this study, we extend Codeço’s classical SI-B epidemic and endemic model from a deterministic framework into a stochastic framework. Then, we formulated it as a stochastic differential equation for the number of infectious individuals I (t) under the role of the aquatic environment. We also proved that this stochastic differential equation (SDE) exists and is unique. The reproduction number, R0, was derived for the deterministic model, and qualitative features such as the positivity and invariant region of the solution, the two equilibrium points (disease-free and endemic equilibrium), and stabilities were studied to ensure the biological meaningfulness of the model. Numerical simulations were also carried out for the stochastic differential equation (SDE) model by utilizing the Euler-Maruyama numerical method. The method was used to simulate the sample path of the SIB stochastic differential equation for the number of infectious individuals I (t), and the findings showed that the sample path or trajectory of the stochastic differential equation for the number of infectious individuals I (t) is continuous but not differentiable and that the SI-B stochastic differential equation model for the number of infectious individuals I (t) fluctuates inside the solution of the SI-B ordinary differential equation model. Another significant feature of our proposed SDE model is its simplicity.
