Item Open Access Extending the importance–performance analysis (IPA) approach to Turkish elderly people’s self-rated home accessibility(Springer, 2019) Afacan, YaseminDesigners are still struggling to make good and fair home designs for elderly people. Although there are a lot of studies on accessibility in homes, there are few methodologies to rate the importance of accessible home attributes, or address the relationships between the most important and most satisfactory attributes (in terms of creating a good fit between the elderly and their homes). This study suggests using the importance–performance analysis (IPA) approach to set accessibility priorities and identify the critical performance factors that determine the elderly’s satisfaction with accessible homes. A self-assessment questionnaire instrument was developed based on housing accessibility literature and conducted with 342 Turkish elderly people chosen through stratified sampling among neighborhood clusters in Ankara, Turkey. The descriptive results and factor analysis of the study are significant in that they indicate significant differences among dwelling types. There were differences in importance and performance priority levels of home accessibility factors associated with each dwelling type. Moreover, the study found that safety and ease of use are the key indicators of home accessibility. According to the results, the IPA could be an effective tool to overcome the messy character of evaluating home accessibility for the elderly. By extending the accessibility attributes with the IPA analysis, it is possible to identify specific accessibility attributes, establish highest and lower priorities for intervention and decide which attributes should be maintained and/or ignored. Thus, this study contributes to the literature on aging by being the first study to explore the applicability of the IPA technique while eliciting elderly people’s accessibility requirements for healthy aging.Item Open Access Parçacık sürü Optimizasyonu ile Dağıtık Tespit(IEEE, 2011-04) İnce, O.; Efe, M.; Arıkan, OrhanDoğadan esinlenerek geliştirilen optimizasyon yöntemleri, kullanım kolaylıkları ve yüksek performansları nedeniyle pek çok farklı disiplinde kendilerine uygulama alanı bulmaktadırlar. Bu çalışmada, son yıllarda yoğun ilgi gören dağıtık tespit problemine, literatürde Parçacık Sürü Optimizasyonu olarak bilinen yöntem uygulanmıştır. Temel bir paralel dağıtık topoloji üzerinde denenen senaryolarda PSO'nun performansının doğruluk ve güvenilirlik ve hız açısından oldukça yüksek olduğu gözlenmiştir.Item Open Access Using webcasts for student presentations: a case study(Emerald Group Publishing Ltd., 2016) Ortaçtepe, D.Purpose – Adopting Davis’ (1989) technology acceptance model (TAM), the purpose of this paper is to investigate the perceived differences between asynchronous presentation tools (webcasts) and in-person presentations in a graduate program designed for the professional development of English as a foreign language (EFL) teachers at a private university in Turkey. Design/methodology/approach – Data were collected for the three different types of presentations (i.e. in-person, video, and Prezi webcasts) the students performed in four different courses throughout the 2013-2014 academic year. Findings – The analysis of the data coming from a three-part questionnaire revealed that students preferred in class presentations for learning purposes but agreed that webcasts were higher in quality as they included audio-visual materials. This study also concluded that for procedural knowledge that came from hands-on activities, students preferred in-person presentations, while for conceptual knowledge, Prezi webcasts were more preferred as they allocated time for students to reflect, do more research on, and effectively contribute to online discussions. Research limitations/implications – The data came from questionnaires; had there been interviews with the students, more insights could have been gained into their perceptions of webcasts as well as how the students actually used them for learning purposes. Originality/value – The studies specifically focussing on the use of audio and video podcasts/webcasts integrated these tools as supplementary materials to course content in traditional lectures. Yet, the use of webcasts as a student presentation tool rather than a duplicate of teachers’ lectures or supplementary materials still remains unknown especially in relation to the extent to which individuals’ acceptance of this instructional technology. © 2016, © Emerald Group Publishing Limited.
