The present exploratory study analyzed the challenges and barriers faced by older adults when accessing legislative e-participation platforms, considering whether the challenges would interfere with these citizens' empowerment. The study employed qualitative evaluations with 20 participants over 60 years old on the e-Cidadania and e-Democracia platforms. It involved responding to a questionnaire, using the platform—while usability tests and observation were conducted—and a post-test interview. The results showed that, in general, the participants were interested in contributing to the e-participation platforms and considered that these systems provide representativeness to them. However, the negative aspects of the design contribute to skepticism among older adults, which can demotivate them to use the resources. The results highlight how the interface features reinforce participants' distrust in the government and distrust in the e-participation process as soon as they realize the information and language are complicated and the resource is difficult to use. They stressed that a more accessible language and a simplified organization of web pages could facilitate the use and boost older people's engagement with these platforms. The results provide reflections on the design of e-participation systems and processes to promote real political participation of older adults in society. Although the study is not representative of the Brazilian older adult population, the qualitative findings and recommendations were delivered to the Accessibility commission of the Brazilian Chamber of Deputies and have been used for guidance and improvements in the platforms.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50153368","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 getting more important to have e-Government systems to supply services to businesses that use them (e-G2B). To improve the Kingdom's national economy, the Information and Government Authority (IGA) has launched a virtual one-stop solution available through multiple channels offering a unified service where citizens and Commercial Registration holders can use a single streamlined form to apply, renew or terminate multiple licenses concurrently; this is the Business License Information System (SIJILAT). This study aims to assess Bahraini customers' satisfaction with the SIJILAT service. A quantitative method is followed with a questionnaire to gather data; six factors: accessibility, information, security, reliability, trust, and perceived ease of use found to effectively affect service quality, and, in which it affects positively and enhances customer satisfaction. The theoretical contribution of this research will enhance the theoretical literature and knowledge related to its topic. The current research will contribute to the few studies conducted in Bahrain and the Middle East on e-government and customer satisfaction with these services. A key outcome of the research will be the ability of e-government officials who make decisions to determine the significant factors that play a role in G2B success, particularly ones to which they should pay attention to obtain the maximum return on their technology investment.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129241779","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}

Farmers face many problems while cultivating plants and they must take precautions at every stage of cultivation. Plants get diseases for various reasons like bacteria, insects, and fungus. Some diseases can be detected by examining the symptoms on the leaves. Early detection of diseases is a major concern and may require a thorough examination of the plants by an agricultural professional. This process is expensive and time taking. Machine learning (ML) algorithms help in image recognition and can be used to detect diseases on time without the need of an agricultural professional. In this project, the diseases in tomato leaves will be detected using image processing. The data from the images are extracted using different vectorization methods and classification algorithms like logistic regression (LR), support vector machine (SVM), and k-nearest neighbors (KNN). Vectors of size 32 × 32 and 64 × 64 are used for training with normalizer scaling and no scaling. Out of the different approaches that were explored, SVM with the radial basis function (RBF) kernel gives the highest accuracy of 85% with no scaling and 64 × 64 image dimension.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624948","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}

An empirical survey of 333 chartered accountants in Ghana was used and the research model was tested using covariance-based structural equation modeling. The results indicate that accountants' participation in AIS design is positively associated with perceived accounting information quality. Additionally, autonomous motivation was found to mediate the relationship between accountants' participation and perceived information quality. In contrast, accountants' perceived usefulness of accounting information does not mediate the relationship between participation in AIS design and perceived accounting information quality. This suggests that accounting information quality is enhanced when accountants participate in AIS design hence play a critical role in information system design. However, accounting information quality is not enhanced through perceived usefulness of accounting information.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50151192","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}

A case study was conducted comprising four CSI ICT learning centers in poor urban communities in Soweto, South Africa. An indigenous theoretical construct was developed, in the form of a systems framework, combining aspects of soft systems methodology (SSM), Ubuntu philosophy and autopoiesis. The aim of the systems framework was to study the impact of the CSI ICT learning centers in a holistic manner. The framework contributed as follows: the descriptive components of SSM assisted to describe the social systems of interest, in each case. The ubuntu lens helped to portray how the community members supported each other to benefit from the learning centers. Autopoiesis elements showed how the learning centers were able to self-produce and collaborate in order to be sustainable. With the insight of the framework, six guiding principles were derived to inform the successful implementation of future CSI ICT interventions.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/isd2.12273","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50133938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inertia represents the continuity of the development of thing. As the speed gradually approaches to the c, the particle's mass also approaches to zero along with its static mass due to the impact of electromagnetic radiation, which is exactly the root where the energy shrinkage effect of high-speed particles comes from, and also the primary factor causing the spectrum redshift. Therefore, the Big Bang theory is wrong. All photons are produced from the high-density particles through electromagnetic radiations. Wherever there is fluctuation, there must be mass, and vice versa. This is the correct understanding of \"wave-particle duality\". No matter the high-speed electrons or the photons produced by them all have different static masses, but their charge-mass ratio is always the same physical constant, and not affected by relativistic effects and electromagnetic radiations. This is the true internal mechanism to constitute the uncertainty principle, and conforms to the experimental facts related to it. It can be proved that in a constant magnetic field, the high-speed electron or photon of having a relatively large curvature radius, which has a high moving speed and less mass, energy and wave frequency. Since Einstein used the absolute space-time established by Newton as the criterion and came to the conclusion that the relative space-time was curved, then he should no longer make circular arguments, that was, used the relative space-time as the criterion, to change the unit length and time established by the absolute space-time.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135905786","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 situation has notably been more challenging for small businesses in developing countries which tend to operate with limited funding and a lack of social and human capital. In these contexts, technology has been argued to be an important resource to allow businesses to adapt and recover from the crisis. In line with this narrative, the pandemic has been linked to growing technology adoption within small firms in developing countries. However, little is known about how small businesses are using such technology as part of strategies: to survive, reposition themselves in the market and potentially “spring back” from the pandemic to thrive in a fundamentally changed environment. In this study, to fill this gap we look to the concept of resilience to examine how technology was adopted to help build resilience. The study focused on small businesses in Kenya and uses in-depth qualitative analysis to unpack the processes of adoption and use. The study findings suggest that the pandemic created an incentive for many small businesses to engage with digital technology, enabling them to stay operational. The study evidenced specific coping strategies that incorporated technology to support resilience, including exploiting demand, acquiring new capabilities, expanding existing capacities, making data-driven decisions, fostering social networks and freezing operations. Consequently, we argue for the need to unpack the processes of technology adoption and the links between technology and economic growth in such settings. During the pandemic, small businesses have typically adopted technology to build resilience appropriate to their context.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50155000","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}

One of the strategies for achieving digital government transformation at the micro level is implementing village information systems (VIS), information systems that village officials manage. Unfortunately, not all villages in Indonesia are thriving in adopting VIS. Therefore, this study aims to answer an overarching puzzle: Why did some village governments successfully adopt VIS while others failed? Using a case-study approach to VIS adoption in Gunungkidul Regency, Indonesia, this study fills the gap in the literature from the technological-organizational–environmental perspective that affects e-government adoption at the village government level. We found four main factors that influence the success or failure of village information systems adoption: (1) VIS interoperability (technology context), (2) the workload of village officers (organizational context), (3) the role of civil society, and (4) the role of a vendor (environmental context). This research enriches the literature by identifying these four factors within the TOE framework, still rarely present in e-government adoption studies, especially in the context of village governments in developing countries. This research has practical implications for the successful adoption of VIS as a village government effort to gain data sovereignty.","PeriodicalId":46610,"journal":{"name":"Electronic Journal of Information Systems in Developing Countries","volume":"89 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50142122","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}
