The dual purpose followed the Solow growth model for output and the expanded Stokey pollution model for CO2 abatement, respectively. An error correction model was used to determine output convergence while a stepwise regression model was applied to ascertain the impacts of renewable energy use on CO2 abatement. The aggregated data on carbon emission intensity, output growth, per capita emission, and population growth were collected from World Bank development indicators for the period of 1990Q1 to 2017Q4 on SSA. Empirical evidence from the study reveals that output converges in SSA at 22% adjustment speed and it is largely accounted for by renewable energy use. The abatement of CO2 using renewable energy is not significant for adoption as the solution to carbon emission mitigation in SSA. The ratio of CO2 to renewable energy use shows a wide gap range of 3.12% to 1%. Therefore, the study recommends intensive pro-renewable energy use policies to close the gap and further redress the significance of renewable energy use as a sustainable alternative to the carbon abatement policy instrument. Furthermore, the sustainability of renewable energy use for a speedy economic growth and carbon emission reduction may not be significant with the current findings on renewable energy use in SSA.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"173 1","pages":"250 - 259"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85018372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is based on analysis of data collected using the structured interview schedule method administered on 132 small-scale pineapple farmers randomly selected from 14 communities in the Akuapem South District of south-eastern Ghana. Agricultural extension agents (96.7%), cooperative societies (83.3%), colleague farmers (70%) and platforms offered by workshops and training sessions (63.3%) were identified as predominant sources of agricultural extension information. Besides, the study showed that 40.9% of farmers were willing to pay for such services, with 28.8% expressing their unwillingness. The results of a chi-square analysis showed a significant relationship between pineapple farmers’ willingness to pay for agricultural extension information with respect to sex, age, educational level, household size, years of experience, farm size, and position in the society. However, marital status and membership of cooperative societies of pineapple farmers were not significant (at ρ ≤ 0.05) and therefore did not affect the pineapple farmers’ willingness to pay for such services. The paper makes a strong case for policy direction that deepens private sector participation and supports a more balanced public-private-partnership arrangement for extension delivery. This may stimulate pluralistic extension delivery, introduce a lot more diversity and enhance farmer acceptance of the need to invest in extension information. This study represents the first-ever study in Ghana on willingness to pay for extension information that focuses exclusively on producers of a horticultural commodity (small-scale pineapple farmers) with their distinguishing characteristic features.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"1 1","pages":"514 - 523"},"PeriodicalIF":0.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75221154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a low adoption of these varieties by the farmers in the study area due to lack of awareness of their impact on food security. Therefore, this study was designed to analyze their impact on food security in southwestern Ethiopia. The data were collected from 385 randomly selected sample households using a semi-structured questionnaire. Both descriptive and econometric analyses were used to analyze the data. The propensity score matching (PSM) model was used to evaluate the impact of climate-smart crop varieties on food security. Descriptive analysis showed that about 59.74% of the respondents were adopters of climate-smart crop varieties. The PSM analysis result revealed that the adoption of climate-smart crop varieties had a significant positive impact on food security. This implies that the likelihood of being food secure would increase by a factor of 0.8 if the climate-smart crop varieties were adopted. Therefore, developing and disseminating the climate-smart crop varieties at the right time through educational improvement (strengthening collaboration) and allocating land for their development is suggested for policymakers to improve food security.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"13 1","pages":"590 - 598"},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78271736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper is to assess the main factors determining export-oriented technological change, using the technological content of exports (high-tech, medium-tech and low-tech exports) as a proxy. For this purpose, instrumental variable regressions are applied to a panel dataset of 33 African countries. The findings revealed that the main determinants of high-technology exports are: imports of components, rule of law, human capital, FDI inflows, GDP per capita and manufacturing. For medium-technology exports, the determinants identified are similar to high-technology exports with population included. The main determinants of low-technology manufactured exports are imports of components, rule of law, population, FDI inflows, GDP per capita and manufacturing. These give policymakers in African countries a targeted approach in formulating policies related to exports by technological category. This paper contributes to the literature in that it assesses the main factors determining export-oriented technological change, using different levels of technological content of exports (high-tech, medium-tech and low-tech exports).","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"101 1","pages":"568 - 579"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84109941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study investigated poultry farmers’ knowledge and the technicality of their practices concerning digital technologies.

Through the administration of well-structured questionnaires, data collected from a total of 136 farmers were employed for the study. The collected data were analyzed with descriptive and multivariate regression analyses. Many (78.7%) had poor knowledge of the use of 3D printers for machine repairs and only 12.5% had good knowledge of blockchain technology for product tracking in the supply chain. Most poultry enterprise operations were serviced manually by farmworkers while only 18.4% facilitated record-keeping with computers. Farmers’ knowledge and practices in digital poultry management (R 2 = 0.61, 0.59) were significantly influenced by the enterprise characteristics like labour strength (b = 1.97, b = 1.09). In conclusion, technological and digitalization lag remains in the poultry industry and this is espoused within the confines of the predominant small-scale enterprise features. Thus, research and development (R&D) should be policy-guided to enable poultry farmers’ sensitization and empowerment with locally adapted and socio-economically appropriate digital technologies. This reveals the incapacitated diffusion of the widely available digital technologies to infiltrate grassroots poultry systems.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"796 1","pages":"562 - 567"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78870603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These expectations are based on a perceived belief in the ability of technology to alleviate some of the challenges associated with manual, paper-based healthcare service delivery. As a result, the drive to implement healthcare technology has gained significant traction in recent years. Unfortunately, the implementation efforts of most health-related technologies have been tainted with several challenges such as fragmentation, lack of interoperability, and co-ordination. As a result, data management and health-related information dissemination across various levels of healthcare systems have been jeopardized. The objective of this study is to identify context-based factors that influence healthcare information systems (IS) implementation in resource-constrained public hospitals. The emphasis is on the public healthcare landscape in South Africa. A qualitative methodological approach was employed. Semi-structured interviews with purposively sampled participants in a public healthcare hospital provided primary data. The findings indicate that factors such as implementation of policies, planning and support strategies, and analysis of healthcare IS’s fitness for purpose in healthcare workflows processes influence successful healthcare IS implementation. Addressing these factors is critical if public healthcare hospitals are to realise fully the transformative potential of technology-based interventions. The contributions made in this paper may be useful to the relevant government bodies, policymakers and other stakeholders interested in advancing adequate healthcare service delivery using healthcare IS.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"48 1","pages":"580 - 589"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87381471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several reasons for utilizing performance measurement in a business, but the most important one is that, when done right, it will increase productivity. Productivity is crucial to a business’s capacity to compete and generate long-term profitability while providing required customer service. A firm will not last in the fierce business world of today if it cannot use its resources effectively to provide value for its consumers. This is especially important for public companies with limited public investments. The creation of adequate and completely usable performance assessment systems, or sets of measures, has, nevertheless, proven to be a very difficult process. This research has focused on the identification of key performance measures and metrics, on which there is still no common understanding. It focuses on identifying the outbound logistical aspect of the pharmaceutical supply chain’s performance measures and metrics. The study is mainly based on previous studies and opinions of the case company’s management staff. Based on a review of previous studies on and discussions with the management staff of the case company, performance measures for a pharmaceutical supply chain (focusing on inventory management and distribution activities) are identified and categorized into quality, time, financial, and productivity measures. Quality measures are observed to be the most crucial metric while assessing pharmaceutical supply chain performance. The case company’s management can utilize the study as a base to develop their own performance measurement system.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"2009 1","pages":"524 - 531"},"PeriodicalIF":0.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82640906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study used a cross-sectional quantitative method where 324 responses were collected through a self-administered online survey questionnaire from South African consumers. The findings revealed that system availability, efficiency, responsiveness, fulfilment, privacy and compensation can be collectively used to measure electronic service dimensions in online shopping. These dimensions have a statistically significant relationship with purchase intention, while customer satisfaction has a mediation effect on the relationship. Customer satisfaction has a full mediation effect on the relationship between electronic service quality dimensions, compensation and privacy and trust with purchase intention and partial mediation between electronic service quality dimensions, responsiveness, efficiency and system availability with purchase intention. These findings inform businesses that are using online shopping platforms and assist them in prioritizing their resources. The contribution of the research is the use of the value-percept paradigm that is enhanced by importance-analysis within customer satisfaction as a mediator on e-service quality and purchase intention. This underpins the importance of customers’ values and, more importantly, a ‘customized’ customer, where ‘one size fit all’ is diminishing during the time of technological advances.","PeriodicalId":7557,"journal":{"name":"African Journal of Science, Technology, Innovation and Development","volume":"1 1","pages":"533 - 546"},"PeriodicalIF":0.0,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79800030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
