Determination of the perceptions of the prospective teachers about Information and Communication Technology (ICT) terms has a remarkable potential to provide input for technology integration plans and ICT training. Within this context, the purpose of this study is to discover the metaphors constructed by prospective teachers for ICT terms. Data were gathered from 180 prospective teachers through a survey. 977 valid metaphors constructed by the participants were grouped into conceptual categories for the six ICT terms. The most common conceptual categories are “developing and changing” for technology, “making life easy” for computers and search engines, “limitless and endless” for the Internet, “means of communication” for social networks, and “addictive items” for video games. Future research should concentrate on investigating the match and mismatches between the intended use of the ICT tools and the perception of the prospective teachers. Keywords: metaphors, ICT, information and communication technology, technology integration, pre-service teacher, teacher education, prospective teachers.

The third quarter of 2020 marks the closure of on-campus face-to-face pedagogies in South Africa’s institutions of higher learning due to Coronavirus disease (COVID-19). The need to maintain social distancing necessitated the transition to emergency remote teaching. A few institutions of higher learnings could move their classes effectively to online and distance education platforms because of their pre-existing experience and some grapple with managing the ‘new normal’. This article reflects on the challenges and opportunities of an emergency remote teaching in institutions of higher learnings during the COVID-19 pandemic. The article adopted a qualitative approach through relevant literature and policy reviews to critically analyse emergency remote teaching during the era of COVID-19. The findings indicate that some staff and students experience challenges related to the lack of resources and exposure to remotely use information and communication technology. The article acclaims that institutions of higher learnings should acquire suitable information and communication technology equipment and develop the requisite facilities, implement rules and regulations for their availability, and adequate maintenance. This recommends promoting technologically compliant ethics within the institution, provide easy access to teaching and learning by both students and academic staff at an affordable and fixed (secure) cost in safe, conducive, and unrestricted environments for students.

Purpose This study aims to present a state-of-the art review on information and communication technology (ICT) research in hospitality and tourism published between 2014 and 2017. Design/methodology/approach A total of 288 full-length articles from eight top-tier hospitality and tourism journals were gathered by harnessing a systematic literature search approach. Subsequently, the authors used a qualitative content analysis to review, analyse and assign all included articles into a framework with six consumer-related and five supplier-related research streams. Findings In terms of volume (i.e. the amounts and ratios of ICT research in top-tier journals by publication year) and variety (i.e. the diversity of research topics), a significant progression of ICT research in hospitality and tourism is observed. However, some old and new knowledge gaps are still inadequately addressed, thus requiring scholars and practitioners to conduct additional research in the future. Practical implications The accumulation of knowledge and actionable clues in this study is expected to keep practitioners updated with the overwhelming volume of ICT research. Originality/value This study contributes to the literature by accelerating the accumulation of knowledge on research topics and setting forth an agenda for future research. The findings also complement prior literature reviews by providing an overview of how knowledge on ICT research in hospitality and tourism has progressed since 2014.

Young adults are becoming less dependent on the car for travel. Increased use of information and communication technology (ICT) has been linked to this trend; this link suggests that ICT enables connection without wheels and thus less travel. This study tested that theory through a survey of young adults in Melbourne, Victoria, Australia. Two competing hypotheses were tested: (a) increased contact through ICT replaces–reduces in-person travel and (b) increased contact through ICT complements–increases in-person travel. The survey found that contact with friends was a high priority for young adults: 81% contacted friends daily through social media, 74% by phone, and 39% in person. A multinomial logistic regression tested associations between frequent in-person contact and several variables. Daily social media and telephone contact with friends was strongly associated with more frequent in-person contact. Daily social media use made someone 6.7 times more likely to have seen friends daily, while daily phone contact made someone 9.9 times more likely to have seen friends daily. The findings supported the complement–increase hypothesis (i.e., ICT use complements in-person contact rather than replaces it). Results are discussed and future research directions proposed.

Demand response is a key element of future power systems due to its capacity to defer grid investments, improve demand participation in the market, and absorb renewable energy source variations. In this regard, demand response can play an important role in delivering ancillary services to power systems. The lack of standardization and ancillary services programs prepared for traditional generators have blocked the participation of demand in these services. Nowadays, increasing needs to ensure the security of supply, renewable fluctuations, and information and communication technology advances are boosting the interest in demand response products to deliver ancillary services. While countries have had lengthy experience with these programs, others are starting from almost zero to develop these programs. To our knowledge, no analysis or standardized comparison exists of the different parameters and prices of demand response in ancillary services among different countries. Our study reviews more than 20 power systems around the world and their programs to classify them according to standard demand response parameters. At the end of the paper we discuss the main characteristics and prices that face demand response in ancillary services markets and a series of policy recommendations to policymakers to improve the deployment on demand participation in ancillary services.

Community Centre

Over the years, Information and Communication Technology (ICT) has become more relevant in today’s society. A telecentre is a community centre where people use, access and utilizes the benefits of the centre through the ICT-based services provided. This paper reviews rural telecentres in Malaysia. The roles and functions of telecentres are explained and discussed to analyze the question on sustainability. The ‘Just Transition’ is a recent and particular transition for rural telecentre to be sustained. Based on the qualitative analysis and review of telecentres’ sustainability, we found that some telecentres can be sustained while others could not. This is because of the impacts of economic, social, environmental and policy sustainability pillars on community telecentres in Malaysia. The review of this paper reveals findings obtained from in-depth interviews with telecentre managers and telecentres’ sustainability depends on natural resources, geographical location, social entrepreneurship, social capital, human resources (competency of leaders) and basic infrastructure. Therefore, future research should be focus on the roles of governance on resource utilization and implement effective public policy for telecentres’ sustainability.

The use of Information and Communication Technology (ICT) has grown enormously in the last decade with computers and smart devices becoming indispensable in tertiary students' study practices, especially in distance education. There is, however, limited documented research on humanizing distance education in terms of studying the ways educators and students use ICT in the process of teaching and learning within this context. This chapter thus provides a background context of the existing studies on distance education as well as the distance education in relation to ICT use. It then examines the degree to which connections between social and technological elements are interrelated in distance education by highlighting the challenges of humanizing distance education. The chapter then outlines a possibility for addressing this challenge, by introducing the socio-technical framework formulated by Bostrom and Heinen (1977a) in researching distance education. The chapter concludes with future research suggestions.
