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…

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 research sought to understand how organizations have adapted to the evolving policy ecosystem to scale and sustain a justice-orientated approach to education reform.

In this study, we conducted a holistic analysis of educational studies on social network analysis (SNA) in higher education. To this end, articles published in Web of Science between 2010 and 2020 on social network analysis at higher education level in the field of educational sciences were analyzed using content analysis. A systematic review of…

This study investigates the organization of the mental lexicon in Spanish as a foreign language in contrast to its structure in Spanish as a native language through semantic networks derived from lexical availability or semantic fluency tasks. To this end, we collected the responses of 75 American learners of Spanish and 75 native speakers in…

Background: Learners of database courses usually encounter difficulties in building entity-relationship (ER) models and relational models for database problems. These difficulties may arise because of semantic gaps between the stages of database design. To investigate this issue, we employed semantic network theory--particularly the concept of…

This article considers the geographies of literacy learning by analysing maps that children drew about their experiences. The maps were created during a mapping-and-talking session with the researchers. Sociomaterial ways of thinking were used to foreground the relationships between people, texts, tools, technologies and spaces, in which literacy…

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.
