Existing studies in Developing and Newly-Industrialised (DNI) countries merely analysed the load demand forecasting methodologies, with little emphasis on consideration of data quality, provision of research agenda and the proposition of the design architecture of load forecasting. Therefore, this paper surveys 22 articles from 18 DNI countries, attempting to investigate the load forecasting methodologies as well as data cleansing mechanisms, and then proposes a general design framework for these countries. A systematic review protocol is applied in this study to achieve unbiased and scientific-based findings. Economic growth, number of customers, price of electricity, temperature, calendar events, and daytime found to be significant drivers of electricity consumption. Furthermore, the findings indicate that 63.64% of the surveyed load forecasting mechanisms considered the inclusion of outlier-removal preprocessors. This paper has pinpointed the issues pertaining to load forecasting in the DNI countries such that a robust model, fitting a context can be built with efficiency.
发展中国家和新兴工业化国家的现有研究仅仅分析了负荷需求预测的方法,很少强调考虑数据质量、提供研究议程和提出负荷预测的设计架构。因此,本文调查了来自18个DNI国家的22篇文章,试图研究负荷预测方法和数据清理机制,然后为这些国家提出了一个通用的设计框架。本研究采用系统评价方案,以获得公正和科学的研究结果。经济增长、客户数量、电价、温度、日历事件和白天被发现是电力消耗的重要驱动因素。此外,研究结果表明,63.64%的负荷预测机制考虑了异常值去除预处理。本文指出了与DNI国家的负荷预测有关的问题,这样就可以高效地建立一个适合上下文的稳健模型。

To examine special education pre-service teachers’ acceptance of assistive technology, this study theorized and established associations between important variables of assistive technology acceptance, including the perceived usefulness, perceived ease of use, attitude, result demonstrability, and behavioural intention. The researcher used the convenient sampling strategy to pick the partakers. 250 questionnaires were given out to the respondents and 139 questionnaires were received. A partial least square technique was applied for the data analysis. The outcome of the inquiry was that perceived ease of use substantially influenced perceived usefulness of assistive technology; perceived usefulness was significantly associated with attitude, and result demonstrability was substantially associated with perceived ease of use. This study added to the current body of knowledge regarding the technology acceptance model for explaining intended assistive technology acceptance in educational settings.

Power continues to be a challenging problem facing institutions which are deploying high performance computing (HPC) facility in developing countries including Tanzania. These institutions like Dar es Salaam Institute of Technology (DIT) can face high operational costs due to the high energy consumption caused by computational operations of HPC systems. Because of the exceedingly high energy cost, diminishing energy consumption has become a major concern in deploying HPC systems. This manuscript per the authors used empirical modeling (EM) to predict the trends of power and cost operation for the year 2018 and 2019 on running HPC system. It was noticed that in addition to optimizing the system configuration, the proposed hybrid algorithm can both minimize completion time while increasing throughput as a result of decreasing energy consumption and maximize resource utilization. The experimental results showed that Infiniband switch can save energy up to 10.7% and the proposed hybrid algorithm can reduce time up to 25% as a result of energy reduction.
对于在包括坦桑尼亚在内的发展中国家部署高性能计算(HPC)设施的机构来说,电力仍然是一个具有挑战性的问题。这些机构,如达累斯萨拉姆理工学院(DIT),由于高性能计算系统的计算操作造成的高能耗,可能面临高昂的运营成本。由于超高的能源成本,降低能源消耗已经成为部署高性能计算系统的主要关注点。本文采用实证模型(EM)预测了2018年和2019年运行高性能计算系统的功率和成本运行趋势。结果表明,该混合算法在优化系统配置的同时,还能最大限度地减少完成时间,提高吞吐量,从而降低能耗,最大限度地提高资源利用率。实验结果表明,Infiniband交换机可节省高达10.7%的能量,而所提出的混合算法由于能量的减少可减少高达25%的时间。

The Internet is one of the most indispensable tools in the present Information Age. It has positively transformed the way the world operates, however, it has also provided a means by which cybercrimes are perpetuated. As people use the Internet, they also become more susceptible to Internet risk. A number of previous studies have reported adolescents’ susceptibility and coping skills within and outside Nigeria. There is however, a dearth of information on cybercrime vulnerability and exposure among adolescents in Osun State, Nigeria. This present study adapts the Routine Activity Theory to investigate the cybercrime exposure of secondary school students in Osogbo, the capital of Osun State, Nigeria. This study adopted a survey research method. The study revealed considerable levels of cybercrime exposure among public senior secondary school students in Osogbo. It was recommended amongst others that the students should be enlightened on positive use of the Internet in order to militate against harm by cybercrime perpetrators.
互联网是当今信息时代最不可或缺的工具之一。它积极地改变了世界的运作方式,然而,它也为网络犯罪的延续提供了一种手段。随着人们使用互联网,他们也变得更容易受到互联网风险的影响。以前的一些研究报告了尼日利亚国内外青少年的易感性和应对技能。然而,在尼日利亚奥松州的青少年中,缺乏关于网络犯罪脆弱性和暴露的信息。本研究采用常规活动理论对尼日利亚奥松州首府奥索博中学生的网络犯罪暴露进行调查。本研究采用调查研究方法。该研究显示,在Osogbo的公立高中学生中,网络犯罪的暴露程度相当高。会议建议,应教导学生如何正确使用互联网,以防止网络罪犯对他们造成伤害。

The Antecedents to the Actual Use of Digital Currencies in Ghana 加纳数字货币实际使用的前因后果
Pub Date : 2021-07-01 DOI: 10.4018/ijictrame.290838
Ernest Akpaku
This study investigates the antecedents to the use of digital currencies in a developing country. In the digital currency literature, behavioral and technological antecedents that affect individuals’ behavior towards the use of digital currencies remain scanty. Drawing on Bitcoin, mobile money, and perfect money as some types of digital currencies, this research adopts the Technology Organization Environment (TOE) framework and the prospect theory. Based on 520 questionnaire responses, this research employs the partial least square structural equation modeling (PLS-SEM) technique. Results from the analysis reveal that technology competence, service, and agent trust, perceived risk, and cost have positive influences on the intention to use digital currencies. Behavioral intention influences the actual use of the technology. However, a country’s regulatory environment does not influence the intention to adopt digital currencies. The research provides important analytical advances and presents practical and economic consequences for the implementation of digital currencies.
本研究调查了一个发展中国家使用数字货币的前因。在数字货币文献中,影响个人使用数字货币行为的行为和技术前因仍然很少。本研究借鉴比特币、移动货币、完美货币等数字货币类型,采用技术组织环境(Technology Organization Environment, TOE)框架和前景理论。本研究以520份问卷为基础,采用偏最小二乘结构方程模型(PLS-SEM)技术。分析结果显示,技术能力、服务和代理信任、感知风险和成本对数字货币使用意愿有正向影响。行为意向会影响技术的实际使用。然而,一个国家的监管环境并不影响采用数字货币的意愿。该研究提供了重要的分析进展,并为数字货币的实施提供了实际和经济后果。

Impact of Technology on University Leadership Effectiveness Among Academic Staff of Some Selected Private Universities in Ghana 加纳部分私立大学学术人员对科技对大学领导效能的影响
Pub Date : 2021-07-01 DOI: 10.4018/ijictrame.290834
B. Ghansah, Ben-Bright Benuwa
Throughout history, leaders in many countries have leveraged on technology to achieve supremacy and power; from German engineering and Japanese electronics to Indian software and Israeli cybersecurity. Patterns in the rise and fall of technological leadership show that such dominance should be understood from traditional factors that signal industrial power, geography and national ambition, and the complexity of emerging technologies. The ubiquitous nature of contemporary technologies and the explosion of mobile and other network-attached devices have been the catalysts and tipping points for most successful countries and leaders. This paper examines how advances in technology impact on university leadership effectiveness among academic staff working in four selected private universities in Ghana. Stratified random sampling method was used to gather data from respondents, comprising administrators, deans and heads of departments from Data Link Institute, Fountainhead University College, Central University and Methodist University College were used in the study.
纵观历史,许多国家的领导人都利用技术来获得霸权和权力;从德国工程和日本电子到印度软件和以色列网络安全。技术领先地位的兴衰模式表明,应该从工业实力、地理和国家雄心以及新兴技术的复杂性等传统因素来理解这种主导地位。当代技术的无所不在,以及移动和其他联网设备的爆炸式增长,一直是大多数成功国家和领导人的催化剂和引爆点。本文考察了技术进步如何影响加纳四所选定私立大学的学术人员的大学领导有效性。采用分层随机抽样的方法收集调查对象的数据,调查对象包括数据链研究所、方源大学学院、中央大学和卫理公会大学学院的管理人员、院长和系主任。

Expediting ICT Policy Implementation in Malawi Through Public-Private Partnership 通过公私伙伴关系加快马拉维ICT政策的实施
Pub Date : 2021-07-01 DOI: 10.4018/ijictrame.290837
Frank Makoza
This paper analysed the role of public private partnership (PPP) in expediting ICT policy implementation. The study used the case of Malawi as an example of a low-income status country in Africa. Data for the study was gathered through key informant interviews and verified using secondary data. The findings showed that public private partnership supported the development and endorsement of the ICT policy as a priority of government activities. Further, the public private partnership supported ICT sector improvements in legal and regulatory frameworks, human capacity, telecommunications infrastructure and ICT access in public institutions. The government benefited from the external parties in supporting the ICT investment programs. To some extent, ICT policy implementation focused more on the strategic level of government programs and the supply side of the ICT sector. The study offers insights into how the public private partnership supported execution of ICT policy programs, processes and politics in the context of a developing country.
本文分析了公私伙伴关系(PPP)在加快信息通信技术政策实施中的作用。该研究以马拉维作为非洲低收入国家的例子。该研究的数据是通过关键信息提供者访谈收集的,并使用二手数据进行验证。调查结果显示,公私伙伴关系支持ICT政策的制定和认可,并将其作为政府活动的优先事项。此外,公私伙伴关系支持信息通信技术部门改进法律和监管框架、人力能力、电信基础设施和公共机构的信息通信技术接入。政府得益于外部各方对ICT投资项目的支持。在某种程度上,信息通信技术政策的实施更多地侧重于政府项目的战略层面和信息通信技术部门的供给侧。该研究深入探讨了在发展中国家,公私伙伴关系如何支持ICT政策项目、流程和政治的执行。

Governments are increasingly using web-based portals to provide information and cost-effective service delivery. While some e-government websites have delivered the intended goal, others are still struggling. This study assessed the quality of the e-government websites using a three-step investigation methodology. Firstly, the quality attributes were generated from literature, then a conceptual framework for e-government websites with four quality dimensions was developed, and lastly, an observation instrument was used to measure the quality attributes of 78 Uganda e-government websites. Most of the websites scored highly on the level of authority, relevance, quality of text, organization of the website, and time to download. The level of attractiveness, content accuracy, objectivity, currency of information, use of multimedia, and multi-language required significant improvements while the use of social media and evidence of security and privacy of the information was hardly visible. A framework is proposed to improve the quality of e-government websites.
各国政府越来越多地使用基于网络的门户网站来提供信息和具有成本效益的服务。虽然一些电子政务网站实现了预期目标,但其他网站仍在苦苦挣扎。本研究采用三步调查方法评估电子政务网站的品质。首先从文献中生成了质量属性,然后构建了包含四个质量维度的电子政务网站概念框架,最后利用观察工具对乌干达78个电子政务网站的质量属性进行了测量。大多数网站在权威性、相关性、文本质量、网站组织和下载时间方面得分很高。吸引力、内容准确性、客观性、信息流通、多媒体使用和多语言的水平需要显著提高,而社交媒体的使用以及信息安全和隐私的证据几乎不可见。提出了一个提高电子政务网站质量的框架。

The level of attractiveness, content accuracy, objectivity, currency of information, use of multimedia, and multi-language required significant improvements while the use of social media and evidence of security and privacy of the information was hardly visible. A framework is proposed to improve the quality of e-government websites.","PeriodicalId":418993,"journal":{"name":"Int. J. ICT Res. Afr.

Epilepsy is a neurological issue that is described by abrupt and irregular seizures. As indicated by the World Health Organisation (WHO), roughly 1% of the total populace are epileptic patients. The abrupt nature of epileptic seizures constitutes a major disabling aspect of the ailment due to the impediments in patients' daily activities. Therefore, a method that can speculate the event of seizures could essentially improve the wellbeing of epileptic patients. Hence, the point of this paper is to build up a model that can anticipate seizures and furthermore characterize them, using a GSR sensor, temperature sensor, and also a pulse rate sensor.
癫痫是一种神经系统疾病,表现为突然和不规则的发作。根据世界卫生组织(WHO)的数据,大约1%的人口是癫痫患者。由于患者的日常活动受到阻碍,癫痫发作的突发性构成了该疾病的主要致残方面。因此,一种可以推测癫痫发作事件的方法可以从根本上改善癫痫患者的健康状况。因此,本文的重点是建立一个可以预测癫痫发作的模型,并进一步表征它们,使用GSR传感器,温度传感器和脉搏率传感器。
