The purpose of this study is to describe how Zoom became the tope video conferencing service across the globe.

This case was developed from secondary sources including industry reports, academic, newspaper, periodical sources, company annual reports, social media sites and company websites. This case has been classroom tested with undergraduates in a strategic management course as a capstone course.

The case study describes the rapid growth of Zoom Communications Inc., a San Jose based publicly traded video conferencing company founded in 2011 by Eric Yuan. It illustrates the competition in the online meeting solutions industry in late 2020, during the COVID-19 lockdown. To explain how Zoom became the top video conferencing service across the globe, the case highlights the attractiveness of the market and the competitive advantage of Zoom over its rivals. Students can evaluate the internal capabilities and competencies of Zoom as well as identify key challenges in the external environment for sustaining Zoom’s competitive advantage.

This case study is suitable for strategic management classes for upper-level undergraduates and at the graduate level for MBA and/or master students. It prepares students to discuss core concepts in strategy, such as competitive strategy and competitive forces that shape strategy.

This study aims to investigate the perceptions of elderly learners in experiencing Zoom learning under the effects of COVID in the case of Hong Kong.

An online survey and focus group interviews have been conducted with quantitative and qualitative approaches, respectively. The survey design was based on the input-process-output (IPO) model conceptual framework and used to assess students’ perceptions regarding their Zoom learning experiences at the Elder Academy of Hong Kong Metropolitan University. Thereafter, selected students were invited to participate in focus group interviews to offer more in-depth comments for analysis purposes. Statistical Product and Service Solutions software and SmartPLS were used for data analysis of the survey, and content analysis was used to summarize opinions from the focus group interviews; thus, a comprehensive picture of elderly learners’ learning experiences on Zoom is presented.

An overall positive perception was the result of elderly learners’ Zoom learning journeys, particularly in the “input” and “process” stages of the IPO model. Yet, their perception of the “learning outcomes achieved” level in the “output” stage was lower among the rest, thus strongly affected by the factors of “interactions” and “teaching” experienced by elderly learners on Zoom. Although the perception of the youngest age group was more positive, none have agreed that Zoom learning was more favourable when compared with the traditional face-to-face mode.

Given Zoom as the short-term replacement option under the COVID pandemic, this study will provide recommendations for educators/institutions to improve their design of the whole learning process for elderly learners on the Zoom platform.

There is a significant decrease in students' attendance in Zoom classes compared to traditional classes. This paper investigates the factors that affect students' attitudes, behavioral intentions and actual use of Zoom for online classes at higher educational institutions (HEIs) in Sri Lanka.

This research uses the technology acceptance model (TAM) as a theoretical model. The data are collected from HEI students via an online survey form. The hypotheses between constructs in the model are tested using partial least squared–structural equation model.

The analysis shows that computer self-efficacy (CSE) affects perceived usefulness (PU) and perceived ease of use (PEU), which affects attitude (ATT) and behavioral intention (BI) and actual use (AU) of Zoom in a chain reaction. Further, PEU affects PU, which, in turn, affects BI. Furthermore, the effect size of PU to BI is larger than ATT to BI.

Students' attendance for Zoom classes mainly depends on CSE, PU and PEU. Therefore, HEIs should promote Zoom with interactive training before teaching online. Further, officials should revise the curriculum in schools to upsurge the CSE of students.

During coronavirus-19, no research was published on students' use of Zoom for online classes in the Sri Lankan context. Moreover, the TAM model has been modified by including CSE as an external variable.

This article offers practical advice to ethnographers venturing into doing participant observations through, but not about, videoconferencing applications such as Zoom, for which the methods literature offers little guidance.

The article stems from a research project about a BioMedical Design Fellowship. As the COVID-19 pandemic hit, the Fellowship converted all teaching activities to online learning via Zoom, and the participant observations followed along. Taking an autoethnographic approach, the authors present and discuss concrete examples of encountered obstacles produced by the video-mediated format, such as limited access and interactions, technical glitches and changing experiences of embodiment.

Changing embodiment in particular initially led the authors to believe that the “messiness” of ethnography (i.e. misunderstandings, emotions, politics, self-doubts etc.) was lost online. However, over time the authors realized that the mess was still there, albeit in new manifestations, because Zoom shaped the interactions of the people the authors observed, the observations the authors could make and how the authors related to research participants and vice versa.

The article succinctly summarizes the key advice offered by the researchers (see Section 5) based on their experiences of converting on-site ethnographic observations into video-mediated observations enabling easy use by other researchers in relation to other projects and contexts.

The article positions video-mediated observations, via e.g. Zoom, which are distinctly characterised by happening in real time and having an object of study other than the online sphere itself, vis-à-vis other “online ethnography” methods. The article further aims to enable researchers to more rapidly rediscover and re-incite the new manifestations of the messiness of ethnography online, which is key to ensuring high-quality research.

The aims of this paper are to explore the rise of cyberhate on the Zoom video conferencing platform at the outset of the coronavirus disease 2019 (COVID-19) pandemic and to examine victimized cases of Zoombombing where it was used as a cyberhate tool. The COVID-19 pandemic has not only impacted our lives and modes of working and studying, but also created new environments for cybercriminals to engage in cybercrime, cyberhate and hacking by exploiting tools such as Zoom. This new phenomenon called “Zoombombing” was first reported in mid-March 2020, when the social distancing and stay-at-home policies in the United States were nationally introduced.

This research conducted a news media content analysis on cases of Zoombombing. To conduct this analysis empirically, a dataset with all of the reported Zoombombing cases from March to April 2020 was created. Google Trends, news media and tweets were used to analyze Zoombombing as a form of cyberhate, particularly digital racism.

The results reveal prevalent Zoom-mediated racism toward Asian Americans, African Americans and Jewish Americans. This study understands Zoombombing from a sociopolitical/cultural perspective through news reporting of victimized cases and explores various ways that Zoombombing shapes, mediates, transforms and escalates racism.

This study is one of the very first studies to analyze Zoombombing in a way that builds upon an emerging body of literature on cyberhate. This paper considers Zoom as a space where curious young people, cybercriminals, extremists and hackers impose their ideologies and beliefs upon newly established online learning and working environments and engage in a struggle for identity recognition in the midst of increasingly accessible vulnerable software and cyberspace.

It takes long time for estimating a copper loss in the coil winding of the motor by using the finite element method (FEM). The purpose of this paper is to calculate fast the copper loss by zooming method.

The authors adopt the “zooming method” to FEM. The authors compare the accuracy and the calculation time with zooming method and normal FEM.

The zooming method contributes to speeding up and the high accuracy of calculation. In the results, the 43-fold speed increase is achieved in the calculation of synchronous motor compared to usual FEM.

The AC copper loss calculation of 3D motor analysis can be calculated in practical computation time.

The main advantage of employment of zooming method is significantly reduction of the computation time in the loss calculation of the coil winding.

The purpose of this research was to reflect on the enablers, challenges and ethical considerations in conducting qualitative research with young children using online methods. The aim was to suggest recommended practices to be put in place for researchers conducting online focus groups and interviews with young children.

This research article explores the use of Zoom video conferencing as a tool to collect qualitative data with young children in Singapore, as an alternative to face-to-face interviews. Taking a child-centred participatory approach, children shared their perspectives of their experiences of child agency in school and at home through their drawings, pictures and dialogue in online group interviews. Schon's model of reflective practice was used to guide the researchers' process of reflections during the research project.

Screen sharing and real-time nature of interactions of Zoom video conferencing enabled building of rapport and children's narratives to be developed while group size and the effect of parental influence provided challenges and ethical issues that needed to be addressed in the research process. Researcher withitness emerged as an essential quality in successful engagement of children in an online focus group discussion.

Online video conferencing platforms like Zoom provide a powerful alternative tool for participatory research with children. It challenges researchers to share control of the interactions and data collection process with children. However, parental interference and effect on data may present itself as a research limitation if not navigated well.

Group size of the focus group has an impact on children's engagement levels and wait time for their turn to speak during group interviews. While parents' presence during the online interview ensured child safety and a comforting presence for the child, parents should also understand their role in the study to avoid interfering with the data collection process.

The Zoom platform resembled onsite interviews' spontaneity of exchanges which allowed the researchers to build rapport with children through small-talk and icebreaker activities. Establishing personal connections and building of trust were essential elements in ensuring children were comfortable participating in the interviews. Observing real-time behaviour and body language of children also allowed for indication of withdrawal of consent and participation by the children.

This research adds new insights to the emerging discussions on collecting data from children via online video platforms with suggestions of new strategies and recommendations to overcome challenges, as well as future implications and potential of using Zoom as an alternative tool for participatory research with children. This research conducted in Singapore provides an Asian context and is different from current literature on this topic, largely focused on western countries' reports.

The purpose of this study was to obtain valuable insights into students’ engagement and experiences within the virtual learning environment, especially in the context of crises. Among the innumerable challenges people throughout the world faced during the first year of the COVID-19 pandemic, those of students in institutions of higher education needing to engage in online academic studies are of special interest. Using an online survey, this study could predict students’ online engagement during the COVID-19 pandemic through three theoretical frameworks: the students’ academic motivation to study, the Big Five personality traits, and loneliness, and with a new tool measuring the participation in the Zoom platform.

To examine the psychological and technological factors predicting the students’ engagement, this study surveyed 547 students from different academic institutions of higher learning.

Findings show that the less lonely the students felt, the less neurotic they were, and the higher they scored in levels of extroversion, agreeableness, consciousnesses and openness to experience, the greater their engagement in their academic studies. In addition, students who were older, more educated, with higher intrinsic motivation and lower lack of motivation were more engaged in their online academic studies. Finally, participating in classes through the Zoom platform and experiencing it positively was a significant predictor of higher academic engagement.

Recognizing these factors can enable educators, institutions of higher learning, counselling services and students to obtain tools for higher engagement in online learning.

This paper discusses the impact of three selected command language facilities on the man—system interface in relation to operational online information retrieval (IR). The concept of data and information is briefly considered in relation to the cognitive viewpoint and Brookes ‘fundamental equation of information science.’ A cognitive IR model is out‐lined, followed by a discussion of variously experienced searchers' knowledge structures. Recently developed online search facilities such as use of positional operators (free text operations), crossfile searching and term frequency analysis (zooming—as the ES A‐Quest command language calls it) are discussed in relation to the IR process. The cognitive view is applied as the means to describe and emphasise the retrieval possibilities and the state of knowledge involved in the interface processes.
