Egocentric networks represent a popular research design for network research. However, to what extent and under what conditions egocentric network centrality can serve as reasonable substitutes for their sociocentric counterparts are important questions to study. The answers to these questions are uncertain simply because of the large variety of…

This paper presents a novel approach for mitigating wormhole attacks on wireless networks using propagation delay timing. The wormhole attack is a persistent security threat that threatens the integrity of network communications, potentially leading to data theft or other malicious activities. While various methods exist for combating wormhole…

Purpose: The purpose of this paper is to examine an essential component of enacting an improvement network: facilitation. In it, the author surfaces "synthesizing" as a core, power-laden facilitation practice that brought together network members from disparate institutions to converge on a shared network aim and theory of improvement.…

This study investigated the impact of designing an online learning environment based on cognitive apprenticeship on students' critical thinking and interaction in CSCL. The one group pretest-posttest quasi-experimental design was used in this study. A questionnaire was used to measure students' critical thinking and social network analysis (SNA)…

This study looked to explore the access to academic social capital for those who have considering dropping out. The research utilized social network analysis, specifically ego networks, to explore how four individuals from an alternative school perceived their own social networks. Name generators, name interpreters, and name interrelators were…

This study aims to identify the formulation differences of groups in two online activities in a university course with different strategies by using social network analysis. Specifically, the connections within the members and identification of brokers were analyzed. Whilst the group enhancing a "community of practice" in WeChat by…

The recent increase in mental health concerns and service utilization for students has been characterized as the "mental health crisis in higher education." At the same time, there are social inequities on who "gets" to be well and under what conditions. This three-paper dissertation analyzes the well-being support networks of…

Using a literacy framework, this case study explores parents' assessment literacy in South Florida (United States). Data were collected using focus-group interviews of public-school parents (N = 32) and a document artifact. Findings illustrate how parents drew upon verbal and virtual information and social interactions to learn about the…

This thesis consists of two projects I worked on simultaneously throughout my PhD. Although neither project builds on the other, both investigate social systems as networks, and draw on a common set of statistical tools and methods.In the first project, I analyse the academic employment and doctoral education of tenure- track faculty at all…

This research sought to understand how organizations have adapted to the evolving policy ecosystem to scale and sustain a justice-orientated approach to education reform. Using descriptive social network analysis to map the policy information network that formed around Community Schools, the authors identified the influential organizations in the…

Background: Process data captured by computer-based assessments provide valuable insight into respondents' cognitive processes during problem-solving tasks. Although previous studies have utilized process data to analyse behavioural patterns or strategies in problem-solving tasks, the connection between latent cognitive states and their…

This systematic literature review analyzed the theoretical frameworks and methodological approaches higher education researchers used to examine the intersections between geography and student college choice. The literature review was guided by Critical Race Spatial Analysis, a conceptual framework and methodological approach for studying the…

Asynchronous online discussions (AODs) are a central component of online courses and have been widely implemented in case-based instruction (CBI). In online CBI, AODs offer learners a medium for making sense of complex problems, as they consider case topics collaboratively with peers and facilitators. Therefore, learners' interactions with others…

This paper explores the nature of integrated networks of practice, and in particular, the important role of "hubs" within networks. Hubs are individuals or groups that energize cross-connections, improve knowledge flow, enhance learning across small clusters of expertise, and play critical roles in building and sustaining robust…

Built environment research has long been interested in understanding the complexities of transitional spaces by investigating their hosted interactions. One approach used in efforts of this kind is actor-network theory (ANT), which conceptualizes built spaces as networks of relations that allow for certain interactions but not others. Previous…
