    Motivation and Information Affordances Towards User Engagement in a Gamified System

    Get PDF
    Gamification is a growing phenomenon, and educational institutions have begun incorporating it into their existing information systems (IS) curriculum. This study seeks to examine how motivational affordances and information quality contribute to student engagement within gamified IS education. Drawing on the frameworks of affordances, information quality, and engagement, this study develops a conceptual model to explain motivational affordances and information quality and its satisfaction effects on students’ engagement in IS education. Our preliminary results show a contrary view that despite the challenges or competition evoked by gamification, it is more satisfying for students to continue using the gamified system. This research-in-progress paper is theoretically important because there are currently no widely accepted theoretical models linking motivational affordances, information quality, and engagement to gamified outcomes, and test the effect on students’ learning behaviours

    Non-Revenue Water Management in Ghana: The Opportunities and Challenges

    Get PDF
    Management of water resources has become a major challenge in Ghana. Efforts to address the situation through serious water sector reforms have provided some improvements, with some serious challenges still persisting globally. This paper takes a view of water management systems in Ghana by focusing on some specific issues such as water production, water sales, total cost and their relationship with the non-revenue water (NRW). The paper adopts “correlation theory” of observations from 2003 to 2009 using Ministry of Water Resources Works and Housing, Ghana data. The findings reveal that, one major problem confronting water resources management in Ghana among others is lack of proper institutional structures and enforcement agencies. The study also revealed that total revenue and total cost of water provision have negative but moderate correlation with NRW but does not give any indication of how good this relationship might be. Again, it was found that where there are aspects of institutional structures, there are limited enforcement agencies for monitoring to ensure compliance.

    Background Globally, the population is rapidly ageing, stemming from a recent decline in mortality, and an increase in life expectancy. About 727 million people globally were aged ≥65 in 2020, and 1 in 6 people will be ≥65 years by 2050. About 7% of Ghana’s population was over 60 years in 2010, and projected to be 12% by 2050. However, the aged are confronted with degenerative conditions that translate into difficulty with mobility. The study was conducted to investigate the difficulty with mobility among the aged in Ghana. Methods The study utilised a cross-sectional dataset of the 2014/2015 (wave 2) Study on Global Ageing and Adult Health and included 1,856 participants aged ≥50 years. The survey command was applied to adjust for sampling biases and the design of the study. At 5% alpha level, a chi-square test of independence was conducted to determine the association between dependent and independent variables. At 95% confidence interval and 5% alpha level, three-level multilevel logistic regression models were performed. The fixed-effects were presented in odds ratio and the random effects were presented using the Intra-Class Correlation. All analysis were performed using STATA statistical software version 16.0. Results Out of the 1,856 participants, 40.3% had difficulty with mobility. Additionally, age (80 and above) [AOR = 3.05, 95%CI = 1.78–5.22], self-reported poor/bad health status [AOR = 2.39, 95%CI = 1.35–4.23], having severe/extreme difficulty performing household activities [AOR = 25.12, 95%CI = 11.49–44.91], experienced severe/extreme bodily pains [AOR = 4.56, 95%CI = 2.16–9.64], severe/extreme sleep problems [AOR = 4.15, 95%CI = 1.68–10.29], and participants with difficulty with sight/vision [AOR = 1.56, 95%CI = 1.16–2.10] had higher odds of difficulty with mobility. Conclusion The aged in Ghana had relatively higher prevalence (40.3%) of difficulty with mobility which is influenced by demographics, health status, and degeneration associated with ageing. This highlights the need to provide social support and strengthen social capital for the aged in Ghana, especially those with difficulty with vision, experiencing bodily pains and had poor health status. Additionally, the Government and stakeholders should provide assistive devices for the aged and geriatric care including recreational fields and care homes to address the health and physical needs of the aged in Ghana

    Patient satisfaction with quality of care at out-patient departments in selected health facilities in Kumasi, Ghana

    Background: Health care is an indispensable element for economic growth and development of individuals and nations. Healthcare service quality is associated with patient satisfaction, ensuring the safety and security of patients, reducing mortality and morbidity, and improving the quality of life. Patient satisfaction with health service is linked to increased utilization following contendness with healthcare received from health providers. There is an increasing public perception of poor quality of care among patients visiting public health facilities in Ghana which translates into service dissatisfaction. Meanwhile, patient dissatisfaction will more likely result in poor utilization, disregard for medical advice, and treatment non-adherence. The study was conducted to assess patients’ satisfaction with quality of care at the outpatient departments of selected health facilities in Kumasi, Ghana. Methods: An institutional-based analytical cross-sectional study was conducted among patients (aged ≥ 18 years) visiting outpatient departments of selected health facilities in Kumasi from October - December, 2019. A systematic sampling technique was adopted to collect quantitative information from 385 respondents using a structured questionnaire. At 95% confidence interval and 5% alpha level, two-level logistic regression models were performed. Model I estimated the crude associations and the effect of covariates was accounted for in Model II. The results were presented in odds ratio with a corresponding 95% confidence interval. All analysis were performed using STATA statistical software version 16.0. Results: Out of the 385 participants, 90.9% of the participants were satisfied with the services they received. Being married [AOR = 3.06, 95%CI = 1.07–8.74], agreeing that the facility is disability-friendly [AOR = 7.93, 95%CI = 2.07–14.43], facility has directional signs for navigation [AOR = 3.12, 95%=1.92–10.59] and the facility has comfortable and attractive waiting area [AOR = 10.02, 95%CI = 2.35–22.63] were associated with satisfaction with health service among patients. Spending more than 2 h at the health facility [AOR = 0.45, 95%CI = 0.04–0.93] and having perceived rude and irritating provider [AOR = 0.14, 95%CI = 0.04–0.51] had lower odds of satisfaction with health service received. Conclusion: There is a high patient satisfaction with services received at out-patient departments which is influenced by a multiplicity of factors; being married, and agreeing that the facility is disability-friendly, has directional signs for navigation, and the waiting area is comfortable and attractive. The study findings call for the need to develop and implement health delivery interventions and strategies (i.e. patient-centered interventions, disability-friendly facilities, and sustainability and improvement of quality service) to improve and sustain patient satisfaction levels with health care service. These strategies must be directed towards addressing inequalities in infrastructural development and inputs needed for healthcare delivery in the health system

    Survival trends among people living with human immunodeficiency virus on antiretroviral treatment in two rural districts in Ghana

    Background The human immunodeficiency virus (HIV) has caused a lot of havoc since the early 1970s, affecting 37.6 million people worldwide. The 90-90-90 treatment policy was adopted in Ghana in 2015 with the overall aim to end new infections by 2030, and to improve the life expectancy of HIV seropositive individuals. With the scale-up of Highly Active Antiretroviral Therapy, the lifespan of People Living with HIV (PLWH) on antiretrovirals (ARVs) is expected to improve. In rural districts in Ghana, little is known about the survival probabilities of PLWH on ARVs. Hence, this study was conducted to estimate the survival trends of PLWH on ARVs. Methods A retrospective evaluation of data gathered across ARV centres within Tatale and Zabzugu districts in Ghana from 2016 to 2020 among PLWH on ARVs. A total of 261 participants were recruited for the study. The data was analyzed using STATA software version 16.0. Lifetable analysis and Kaplan-Meier graph were used to assess the survival probabilities. “Stptime” per 1000 person-years and the competing risk regression were used to evaluate mortality rates and risk. Results The cumulative survival probability was 0.8847 (95% CI: 0.8334–0.9209). The overall mortality rate was 51.89 (95% CI: 36.89–72.97) per 1000 person-years. WHO stage III and IV [AHR: 4.25 (95%CI: 1.6–9.71) p = 0.001] as well as age group (50+ years) [AHR: 5.02 (95% CI: 1.78–14.13) p = 0.002] were associated with mortality. Conclusion Survival probabilities were high among the population of PLWH in Tatale and Zabzugu with declining mortality rates. Clinicians should provide critical attention and care to patients at HIV WHO stages III and IV and intensify HIV screening at all entry points since early diagnosis is associated with high survival probabilities

    Comparative efficacy of low-dose versus standard-dose azithromycin for patients with yaws: a randomised non-inferiority trial in Ghana and Papua New Guinea

    Background: A dose of 30 mg/kg of azithromycin is recommended for treatment of yaws, a disease targeted for global eradication. Treatment with 20 mg/kg of azithromycin is recommended for the elimination of trachoma as a public health problem. In some settings, these diseases are co-endemic. We aimed to determine the efficacy of 20 mg/kg of azithromycin compared with 30 mg/kg azithromycin for the treatment of active and latent yaws. Methods: We did a non-inferiority, open-label, randomised controlled trial in children aged 6–15 years who were recruited from schools in Ghana and schools and the community in Papua New Guinea. Participants were enrolled based on the presence of a clinical lesion that was consistent with infectious primary or secondary yaws and a positive rapid diagnostic test for treponemal and non-treponemal antibodies. Participants were randomly assigned (1:1) to receive either standard-dose (30 mg/kg) or low-dose (20 mg/kg) azithromycin by a computer-generated random number sequence. Health-care workers assessing clinical outcomes in the field were not blinded to the patient's treatment, but investigators involved in statistical or laboratory analyses and the participants were blinded to treatment group. We followed up participants at 4 weeks and 6 months. The primary outcome was cure at 6 months, defined as lesion healing at 4 weeks in patients with active yaws and at least a four-fold decrease in rapid plasma reagin titre from baseline to 6 months in patients with active and latent yaws. Active yaws was defined as a skin lesion that was positive for Treponema pallidum ssp pertenue in PCR testing. We used a non-inferiority margin of 10%. This trial was registered with ClinicalTrials.gov, number NCT02344628. Findings: Between June 12, 2015, and July 2, 2016, 583 (65·1%) of 895 children screened were enrolled; 292 patients were assigned a low dose of azithromycin and 291 patients were assigned a standard dose of azithromycin. 191 participants had active yaws and 392 had presumed latent yaws. Complete follow-up to 6 months was available for 157 (82·2%) of 191 patients with active yaws. In cases of active yaws, cure was achieved in 61 (80·3%) of 76 patients in the low-dose group and in 68 (84·0%) of 81 patients in the standard-dose group (difference 3·7%; 95% CI −8·4 to 15·7%; this result did not meet the non-inferiority criterion). There were no serious adverse events reported in response to treatment in either group. The most commonly reported adverse event at 4 weeks was gastrointestinal upset, with eight (2·7%) participants in each group reporting this symptom. Interpretation: In this study, low-dose azithromycin did not meet the prespecified non-inferiority margin compared with standard-dose azithromycin in achieving clinical and serological cure in PCR-confirmed active yaws. Only a single participant (with presumed latent yaws) had definitive serological failure. This work suggests that 20 mg/kg of azithromycin is probably effective against yaws, but further data are needed

    The Radially Swollen 4 Separase Mutation of Arabidopsis thaliana Blocks Chromosome Disjunction and Disrupts the Radial Microtubule System in Meiocytes

    The caspase-family protease, separase, is required at the onset of anaphase to cleave the cohesin complex that joins replicated sister chromatids. However, in various eukaryotes, separase has acquired additional and distinct functions. A single amino-acid substitution in separase is responsible for phenotypes of the Arabidopsis thaliana mutant, radially swollen 4 (rsw4). This is a conditional mutant, resembling the wild type at the permissive temperature (∼20°C) and expressing mutant phenotypes at the restrictive temperature (∼30°C). Root cells in rsw4 at the restrictive temperature undergo non-disjunction and other indications of the loss of separase function. To determine to what extent separase activity remains at 30°C, we examined the effect of the mutation on meiosis, where the effects of loss of separase activity through RNA interference are known; and in addition, we examined female gametophyte development. Here, we report that, at the restrictive temperature, replicated chromosomes in rsw4 meiocytes typically fail to disjoin and the cohesin complex remains at centromeres after metaphase. Meiotic spindles appear normal in rsw4 male meiocytes; however the mutation disrupts the radial microtubule system, which is replaced by asymmetric arrays. Surprisingly, female gametophyte development was relatively insensitive to loss of separase activity, through either rsw4 or RNAi. These effects confirm that phenotypes in rsw4 result from loss of separase activity and establish a role for separase in regulating cell polarization following male meiosis

    Gamifying Sakai: Understanding Game Elements for Learning

    No full text
    In recent times, the use of game designs in a non-game context known as gamification has been postulated to encourage learning and business engagement. This paper explores the perceived understanding of students and administrators concerning game elements as a precursor to gamifying Sakai which is a Learning Management System adopted by the University of Ghana. Survey data was gathered from both undergraduate and postgraduate students (N=40) and interview granted to the Sakai management team. The study examined their gaming experience, expectation of gamification in Sakai and perceive usefulness of game elements as an engagement and interactive tools. The findings show that gamification is a new concept and the data also revealed a positive attitude towards adding game elements to Sakai. Further, students opted for leaderboards and teams in Sakai to encourage teamwork, excitement in learning and an incentive to visit Sakai frequently. The findings implications are discussed
