In the past five years, research has raised concerns regarding the appropriate support citizens experience from e-government services. Their concerns were noted through feedback by citizens regarding their low satisfaction levels and consequently, low levels of adoption of such e-government services. This correlates with factors such as a detailed assimilation process, streamlined services, state-of-the-art technology, agile accessibility, awareness and trust. In response to the raised concerns, the current research was conducted, which systematically and in the form of a mapping review/systematic map, examined various constructs of 22 articles selected from different databases or literature on the appropriate e-government service support and influences on end-users. Based on the analysis of the study findings, five hypotheses have been developed. These include the following:1)The intent to use e-government service is enhanced via the support of a detailed assimilation process;2)Support for citizens by designing streamlined services significantly enhances the support of e-government services;3)Support for citizens by designing state-of-the-art technology greatly enriches e-government services;4)Agile accessibility to the e-services significantly improves the use of e-government services;5)Supporting citizens by developing awareness and trust significantly enhances the intent to use e-government services.From a theoretical perspective, the conclusion is that privacy calculus constructs should play a significant role if citizens need to be supported by government in their use of e-government services.
在过去的五年中,研究提出了关于公民从电子政务服务中获得适当支持的关注。市民对电子政府服务的满意度较低,因此采用电子政府服务的程度较低,反映了他们的关注。这与详细的同化过程、精简的服务、最先进的技术、灵活的可访问性、意识和信任等因素有关。针对提出的关切,目前进行的研究系统地以制图审查/系统地图的形式,审查了从不同数据库或文献中选出的关于适当的电子政务服务支持及其对最终用户的影响的22篇文章的各种结构。在分析研究结果的基础上,提出了五个假设。其中包括:1)通过对详细的同化过程的支持,提高了使用电子政务服务的意图;2)通过设计简化的服务来支持公民,显著增强了对电子政务服务的支持;3)通过设计最先进的技术来支持公民,极大地丰富了电子政务服务;4)灵活地访问电子政务服务,显著提高了电子政务服务的使用;5)通过培养意识和能力来支持公民信任显著增强了使用电子政务服务的意愿。从理论的角度来看,结论是如果公民在使用电子政务服务时需要政府的支持,隐私演算结构应该发挥重要作用。

Higher education institutions need to deliver quality education to diverse students in increasingly larger classes. Mobile learning management systems are shown to offer benefits such as access to teaching and learning resources, regardless of time and location. This study analysed quantitative survey data from 179 third- year Information Systems students to assess their attitudes to using their institutional mobile application, iKamva. Data was collected via an online survey and were analysed using Partial Least Squares (PLS) to test the research model, based on the Technology Acceptance Model. Results indicated that perceived usefulness and perceived ease of use positively influenced students’ attitude towards using the mobile application. However, this attitude towards using the mobile application did not translate into the actual usage of the iKamva mobile application as less than 25% of students used the tool. These findings indicate that despite the availability of the mobile learning management system, it does not necessarily translate into the usage thereof as it was found that students prefered using the electronic learning management system.
高等教育机构需要在越来越大的班级中为多样化的学生提供优质教育。研究表明,移动学习管理系统可以提供各种好处,例如无论何时何地都可以获得教学和学习资源。本研究分析了179名信息系统三年级学生的定量调查数据,以评估他们对使用机构移动应用程序iKamva的态度。数据通过在线调查收集,并使用偏最小二乘法(PLS)进行分析,以技术接受模型为基础检验研究模型。结果表明,感知有用性和感知易用性正向影响学生对移动应用程序的使用态度。然而,这种使用移动应用程序的态度并没有转化为iKamva移动应用程序的实际使用情况,因为只有不到25%的学生使用该工具。这些发现表明,尽管移动学习管理系统的可用性,它并不一定转化为使用,因为我们发现学生更喜欢使用电子学习管理系统。

Inclusivity in education fosters the academic development and social integration of all learners despite their disabilities. In spite of the support extended by higher education institutions towards inclusion, there is a substantial exclusion of visually impaired learners in engineering courses in South Africa. This indicates that there is a lack of an effective framework that guides institutions in South Africa to promote the provision of visually impaired learners in engineering. The purpose of this paper is to firstly obtain the perceptions of visually impaired learners from special schools in the Free State Province regarding the provision of visually impaired learners for engineering education. Secondly, the paper aims to investigate which ICT tools can be used to overcome some of the challenges that visually impaired learners may face in engineering education. Focus groups were used to collect qualitative data from visually impaired learners in the Free State Province of South Africa. The lack of awareness about engineering and the lack of engineering tools were some of the key challenges raised. ICT tools such as iNETSim, AudioMath, PRISCA, LoggerPro, MoodleVox etc. are recommended for specific engineering courses. It is further recommended that tertiary institutions seek to address the challenges faced by visually impaired learners, so that they too may contribute to the socio-economic development of South Africa. This paper forms part of a larger study that aims at developing a framework for the successful adoption and use of ICTs in engineering courses in higher education institutions of South Africa.
教育的包容性促进了所有学习者的学业发展和社会融合,尽管他们有残疾。尽管高等教育机构在包容方面提供了支持,但在南非的工程课程中,视障学生基本上被排除在外。这表明南非缺乏一个有效的框架来指导各机构促进为工程专业的视障学习者提供服务。本文的目的是首先获得自由邦省特殊学校视障学生对提供视障学生工程教育的看法。其次,本文旨在探讨哪些ICT工具可以用来克服视障学习者在工程教育中可能面临的一些挑战。使用焦点小组收集南非自由州省视障学习者的定性数据。缺乏对工程的认识和缺乏工程工具是提出的一些关键挑战。ICT工具,如iNETSim, AudioMath, PRISCA, LoggerPro, MoodleVox等,推荐用于特定的工程课程。还建议高等教育机构设法解决视障学习者面临的挑战,使他们也能为南非的社会经济发展作出贡献。本文是一项更大的研究的一部分,该研究旨在为南非高等教育机构的工程课程成功采用和使用信息通信技术制定一个框架。

Evidence Based Medicine, is a practice, where medical actions/decisions are undertaken on the basis of best available evidence-based recommendations. In this context, we propose a system for automatic grading of evidence.Evidence grading is approached as a multi-label classification task. Here, classes represent grades, in a widely used Strength of Recommendation Taxonomy (SORT). Numerous ensemble methods are experimented with. It was found that the most successful one used Support Vector Classifiers, trained on multiple high level features, results of which are used to train a Random Forest Classifier. The best achieved accuracy score was 75.41%, which is a significant improvement over the baseline of 48%, achieved by classifying all instances as the majority class. It was also found that the most important predictor is the publication type of articles comprising the body of evidence. The designed system is tuned for use with medical publications and SORT. However, due to it’s generality, it can easily be used with other evidence grading systems.
循证医学是在现有最佳循证建议的基础上作出医疗行动/决定的一种做法。在此背景下,我们提出了一个自动分级证据的系统。证据分级是一个多标签分类任务。这里,在广泛使用的推荐强度分类法(SORT)中,类代表分数。实验了许多集成方法。结果发现,最成功的一种方法是使用支持向量分类器,对多个高级特征进行训练,其结果用于训练随机森林分类器。通过将所有实例分类为多数类,获得的最佳准确率得分为75.41%,比基线的48%有了显著提高。研究还发现,最重要的预测因子是构成证据体的文章的发表类型。所设计的系统经过调整,适用于医学出版物和SORT。然而,由于它的通用性,它可以很容易地与其他证据分级系统一起使用。

The Internet of Things (IoT) consists of several patterns that address a variety of problems encountered in the design and construction of reference architectures. Essentially, these patterns represent a set of conventional solutions and technologies that are used in the IoT paradigm to create ambient intelligence. However, in order for the IoT practitioners to use these patterns effectively, a catalogue that groups and classifies them in a systematic manner is required. Such a catalogue must facilitate easy and quick retrieval of the pattern, and clearly describe the intended purpose of each pattern. At the moment, no such catalogue exists, and the reviewed catalogues in the literature are either cumbersome or address these issues inadequately. This makes it difficult for users and the IoT practitioners to easily choose the relevant pattern for the given problem. Due to the large number of the IoT patterns, it is difficult to organise them in a manner that facilitate systematic classification. In this study, we propose a methodical, fivestep approach by which we can arrange these patterns for easy identification. The nature of this paper is theoretical, thus we focus on exploring some linguistic theories and algebraic structures that make up the core essence of this multifaceted process.
物联网(IoT)由几个模式组成,这些模式解决了在设计和构建参考体系结构时遇到的各种问题。从本质上讲,这些模式代表了一组传统的解决方案和技术,这些解决方案和技术在物联网范式中用于创建环境智能。然而,为了使物联网从业者有效地使用这些模式,需要一个以系统的方式对它们进行分组和分类的目录。这样的目录必须方便快捷地检索模式,并清楚地描述每个模式的预期用途。目前,没有这样的目录存在,文献中审查的目录要么繁琐,要么不充分地解决这些问题。这使得用户和物联网从业者很难轻松地为给定问题选择相关模式。由于物联网模式数量众多,很难以一种便于系统分类的方式对它们进行组织。在这项研究中,我们提出了一个有条理的,五步的方法,通过它我们可以安排这些模式,以便于识别。本文的性质是理论性的,因此我们着重探讨构成这一多面过程核心本质的一些语言学理论和代数结构。

Digital technologies and innovations in particular, are amongst the most trending topics in IS research. ICT, in its near-ubiquitous nature is now a part of our everyday lives widely regarded as a de facto enabler of socio-economic transformation. In this knowledge economy, there is a need for all communities to adopt and adapt to digital platforms. One strategic aspect for the proliferation of digital technologies is through digital innovation hubs. This paper explores digital innovation hubs in different social contexts based on an extensive range of literature. This has important implications to inciting constructive debate on the role of digital innovation hubs in socio-economic development and draws attention to the prospects of future work espoused in a holistic research framework for measuring the actual impact of digital innovation hubs.
特别是数字技术和创新,是信息系统研究中最热门的话题之一。信息通信技术几乎无处不在,现在已成为我们日常生活的一部分,被广泛认为是社会经济转型的实际推动者。在这个知识经济时代,所有社区都需要采用和适应数字平台。数字技术扩散的一个战略方面是通过数字创新中心。本文在广泛文献的基础上探讨了不同社会背景下的数字创新中心。这对于激发关于数字创新中心在社会经济发展中的作用的建设性辩论具有重要意义,并引起人们对衡量数字创新中心实际影响的整体研究框架所支持的未来工作前景的关注。

Electronic health records (EHRs) are used by health care agents for capturing and monitoring of data relevant to the young adults visiting health care centres. An EHR system is referred to as broad record of a patient’s health history that can be used by the patient’s health care agents to diagnose patient health status. However, young adults have developed trust issues using their mobile devices to access these electronic health records. The aim of this study was to investigate the young adults’ trust issues concerning mobile access to electronic health records. This study employed a quantitative, survey design to collect data. A total of 200 young people were selected making use of a convenience sampling technique, with a response rate of 81.0%. Data was analysed making use of descriptive statistics and Pearson’s correlation. The key finding of this study is that the lack of legislation that governs EHRs, user training and commitment, and poor ICT infrastructure results in young adults’ mistrust in sharing their medical information. The study concludes by proposing a framework to improve trust in EHRs among young adults. The framework consists of 2 factors, integrity and ability of EHRs to improve health care, which are important to consider when investigating trust issues of young adults using mobile EHRs. The study makes three recommendations to the National Department of Health (DoH) around revisiting the e-Health strategy in South Africa, improving EHRs infrastructure and services in South Africa and finally providing education and training to users of mobile devices at the University of Fort Hare, South Africa.
卫生保健代理人使用电子健康记录(EHRs)来获取和监测与访问卫生保健中心的年轻人有关的数据。EHR系统被称为患者健康史的广泛记录,患者的医疗保健代理可以使用该记录来诊断患者的健康状况。然而,年轻人在使用移动设备访问这些电子健康记录时产生了信任问题。本研究的目的是调查年轻人对移动设备访问电子健康记录的信任问题。本研究采用定量调查设计来收集数据。采用方便抽样法,共抽取200名青年,回复率为81.0%。利用描述性统计和Pearson相关分析数据。这项研究的主要发现是,缺乏管理电子病历的立法、用户培训和承诺,以及信息通信技术基础设施落后,导致年轻人不信任分享他们的医疗信息。该研究最后提出了一个框架,以提高年轻人对电子病历的信任。该框架由两个因素组成,即电子病历的完整性和改善医疗保健的能力,在调查使用移动电子病历的年轻人的信任问题时,这两个因素是重要的考虑因素。该研究向国家卫生部(DoH)提出了三项建议:重新审视南非的电子保健战略,改善南非的电子病历基础设施和服务,最后向南非黑尔堡大学的移动设备用户提供教育和培训。

A novel method to cross impact matrix creation is presented in this paper to overcome the inherent challenges of cross impact analysis. The cross impact matrix is a strong prerequisite for numerous impact factor analysis methods which are used in future studies, military intelligence, game simulation and various business contexts. The method draws on the property of transitivity of preference as a key concept for the creation of the cross impact matrix from preference chains. A number of drawbacks associated with the traditional development and creation of the cross impact matrix are addressed and are overcome using this novel approach. An existing cross impact matrix is used to test the validity and reliability of the method developed.
本文提出了一种新的交叉碰撞矩阵生成方法,克服了交叉碰撞分析的固有挑战。交叉影响矩阵是未来研究、军事情报、游戏模拟和各种商业环境中使用的众多影响因素分析方法的先决条件。该方法利用偏好的传递性作为一个关键概念,从偏好链中创建交叉影响矩阵。使用这种新方法解决并克服了与传统开发和创建交叉冲击矩阵相关的许多缺点。利用已有的交叉冲击矩阵验证了所开发方法的有效性和可靠性。

The objective of the current research was to examine the integration and interoperability of a security and privacy policy framework for the adoption of e-government services in developing countries such as South Africa. Anchored upon the objective and using meta-analysis, the research draws on and juxtaposes e-government frameworks for information privacy and security in South Africa. The meta-analysis referred to was a qualitative interpretive systematic review of past and present research. We conclude by interrogating the role of framework integration and interoperability in the adoption of e-government services in a developing country such as South Africa.
当前研究的目的是检查在南非等发展中国家采用电子政务服务的安全和隐私政策框架的集成和互操作性。本研究以目标为基础,运用元分析,借鉴并并列了南非信息隐私和安全的电子政务框架。所引用的荟萃分析是对过去和现在研究的定性解释系统综述。最后,我们探讨了框架集成和互操作性在南非等发展中国家采用电子政务服务中的作用。
