The Use of Question Modification Strategies to Differentiate Instruction in Eritrean Mathematics and Science Classrooms

2023

This qualitative study aimed at examining the question modification strategies Eritrean elementary and middle school teachers used to differentiate their instruction and meet the diversity in the classroom as well as the functions these strategies served in classroom interactions. The research data consisted of videotaped recordings (N = 11 videotaped lessons) of classroom interactions in eight mathematics and science classrooms, which were analysed through interaction analysis. The findings showed that Eritrean teachers utilised the following five question modification strategies either independently or in combination: repetition; rephrasing; clarification; decomposition; and code-switchin…

A Novel Bio-Inspired Approach for High-Performance Management in Service-Oriented Networks

2021

Service-continuity in distributed computing can be enhanced by designing self-organized systems, with a non-fixed structure, able to modify their structure and organization, as well as adaptively react to internal and external environment changes. In this paper, an architecture exploiting a bio-inspired management approach, i.e., the functioning of cell metabolism, for specialized computing environments in Service-Oriented Networks (SONs) is proposed. Similar to the processes acting in metabolic networks, the nodes communicate to each other by means of stimulation or suppression chains giving rise to emergent behaviors to defend against foreign invaders, attacks, and malfunctioning. The mai…

Whole class interaction in the adult L2-classroom : The case of Swedish for immigrants

2019

This article focuses on verbal interaction in whole class teaching in second language education for adults in Sweden. The article draws on theories treating language as multiple resources that are situated and embedded in material life, and including complex and diverse linguistic, semiotic, physical material and social resources. The material for the article was created in a project based in linguistic ethnography in the form of an action research project, including two municipal Swedish for Immigrants (SFI) schools. The interaction patterns that occurred challenged students’ language proficiency in ways that stimulated meaning negotiation through what we call extended interactions. This s…

Smartphone usage among older adults

2021

Abstract Problematic smartphone usage, associated with impaired daily functioning, has gained increased attention among researchers. However, extant research is focusing on adolescents and younger adults. This paper investigates smartphone usage among older adults, of which less is known. To do so, we conducted a cross-sectional survey of 154 smartphone users (60+ years) in Norway using structural equation modeling (PLS-SEM). We examined the contributing roles of loneliness, habit, social influence, emotional gain, fear of missing out, self-control, and problematic smartphone usage. We further investigated how older adults engage with their smartphones. Our findings suggest that older adult…

The association of the availability of offline gay scenes and national tolerance of homosexuality with gay and bisexual men's sexual online dating be…

2020

Abstract Based on a uses and gratifications perspective on media use, in this paper I analyze the important role played by dating sites for men who have sex with men (MSM) in their efforts to find offline sexual partners. To do so, I conducted two quantitative surveys. In Study 1, I compared the online dating behavior of 12,328 MSM from Germany and Austria with the availability of offline sexual gay venues and how frequently MSM visit such venues. In Study 2, I used a global sample of 30,789 MSM to compare the frequency and recency of online dates of men living in countries that support male homosexuality and those in countries that criminalize it. The findings suggest that MSM-specific dat…

“Thanks for Watching.” The Effectiveness of YouTube vlogendorsements

2019

This study examines the effectiveness of brand endorsements in vlogs (video blogs) by assessing the role of audience participation, parasocial relationship, and valence toward vlog endorsements on the perceived credibility of the vlogger and brand attitudes. Four experimental conditions were created on Qualtrics based on a YouTube vlog where the endorser reviewed a few products. The data were collected using Mturk and analyzed with 203 usable responses. The findings indicate that audience participation in the vlog enhances para-social relationship with the vlogger, thus further fostering the vlogger's perceived credibility as an endorser. Additionally, the valence of the audience's attitude…

A virtual reality system for the treatment of stress-related disorders: A preliminary analysis of efficacy compared to a standard cognitive behaviora…

2011

This paper presents preliminary efficacy data in a controlled study of the use of a virtual reality (VR) system for treating stress-related disorders (Post-Traumatic Stress Disorder, or PTSD; Pathological Grief, or PG; and Adjustment Disorders, or AD). ''EMMA's World'' is a VR application in which patients can explore negative experiences to the degree required for their specific therapeutic needs. To accomplish therapeutic goals, a series of virtual elements is customized to be meaningful to the user; the elements contain the fundamental emotional components that the person must confront. Thirty-nine participants diagnosed with PTSD (N=10), PG (N=16), and AD (N=13) were randomly assigned t…

Students’ Perception of Cell Phones Effect on their Academic Performance: A Latvian and a Middle Eastern University Cases

2021

This study is unique in its attempt to combine the Technology Acceptance Model (TAM) with external variables and the Information System Continuance Theory, in the context of mobile learning. It extends TAM with the external variables perceived mobility and perceived enjoyment. Mainly, students’ perception of cell phones effect on their academic performance is investigated. The study was conducted at two different universities—in Europe and the Middle East. Cell phone usage is analyzed from the perspective of mobile learning. The data in this study were collected from 103 students from the University of Latvia and 106 students from a Middle Eastern private American University. This study sho…
