Consumer Behavior of Smartphone Users in Turkey: A Qualitative Research on Baby Boomers
Get PDFOver the last few years, millions of users have switched from regular phones to smartphones. Smartphone usage varies considerably between different users, ranging from a couple of hours to 14 hours per day. Various features of smartphones make them good candidates for the delivery of behavioral interventions. First, as portable devices thatare highly valued by individuals, they tend to be switched on and remain with the owner throughout the day. The literature on smartphone app feasibility and acceptability is encouraging. The exploration of user viewpoints has often been limited and fairly superficial. There is little in depth, qualitative research allowing users to describe their experiences, views, and usage patterns. Several important areas are inadequately addressed by previous research. First, there is an absence of research on how older adults perceive and use apps for behavior change. Few reports exist discussing the development of interventions for this population. Given the lack of knowledge about smartphone addiction, the use of a qualitative method was deemed appropriate. We adopted an inductive strategy to investigate the antecedents, behaviors and outcomes associated with smartphone addictive use. A total of 12 participants were recruited. All participants completed a brief questionnaire providing demographic, lifestyle, and smartphone-related data. Participants comprised of 6 females and 6 males. Each session was guided by aninterview schedule adapted from the Questionnaire of Vaghefi et al. (2016) to assess more objectively the level of smartphone dependence of our interviewees. The coding was validated by two researchers. A consensus approach was used to resolve discrepancies. From our data analysis, we identified some patterns and could distinguish profiles of smartphone users
Bilgisayar Destekli Eğitimde Teknolojik Kolaylaştırıcı Olarak Facebook Platformu ve Avantajları
Get PDFBilgisayar destekli eğitimde bilgi ve deneyim içeriğine erişmeye çalışırken temel noktalarda aksamalar olduğu düşünülmektedir. Temel sorunsal, teknoloji ile karşılaşan öğrencinin, bu etkileşim sürecini başka bir aracı olmadan sağlıklı bir şekilde tamamlayamamasıdır. Gündemdeki uygulamalarda, teknoloji, etkileşimi kolaylaştırıcı bir rol üstlenmekten öte temel ve tek araç rolündedir. Çeşitli araştırmalar etkileşime destek olacakşekilde bir aracının varlığını önemli bir gereklilik olarak önermektedir. Bu çalışma,teknolojiyi temel araç olarak görmek yerine, etkileşimin sağlıklı ve eksiksiz yürümesini sağlayacak bir kolaylaştırıcı olarak ele almayı tercih etmektedir.

Subjective well being among university students
Get PDFThe research aims at: 1- Measuring subjective well-being of university students. 2- Knowing the significance of differences in subjective well-being of university students according to gender (male/female) and specialization (scientific/humanity). As for the concept of subjective well-being, the researchers has built a scale for measuring subjective well-being depending on the theory of subjective well-being for Edward Denier . The scale consists of (30) items which have been formulated by using self-report statements. There are five alternatives for answering ( always, often, sometimes, seldom and never), they are given when scoring (1, 2, 3, 4, 5), respectively for positive items and vice versa if the items are negative. After that, the researcher has ascertained the validity of her scale by exposing it to (15) experts in psychological counseling, psychology and educational and psychological sciences, where all the items are accepted. The researchers has also ascertained the discriminatory power of the scale through using two methods : the method of two extreme samples and the association of the item grade with the total grade through administering the scale on (400) male and female students chosen randomly categorically from four colleges in the university of Al-mustansiriah, namely, science, engineering, arts and education colleges. As a result the final form of the scale consists of (30) items for measuring subjective well-being. The researchers has ascertained the validity of the scale by using two indicators, they are: face validity which includes exposing the items in a questionnaire to a number of experts, and by construct validity which includes the association of the item grade with the total grade. The reliability of the scale has been ascertained by using two ways, namely, re-test, where the reliability coefficient is (0,85) and Alph-Cronbach, where the reliability coefficient is (0,84) when applying the scale on (50) students from the college of engineering, department of electricity and college of education, department of history in the university of Al-mustansiriah. After ascertaining the psychometric properties of the two scales and their items, they are administered on the basic sample of the research which consists of (400) students chosen randomly categorically. The data are analyzed by using the statistical package for social sciences (SPSS). However, the results show: 1- University students do not have subjective well-being. 2- There are no statistically significant differences in subjective well-being according to gender (male/female) and specialization (scientific/humanity )
An Ideal Steady State Output Voltage of a Single-Phase PWM Inverter
Get PDFThis paper presents investigation on the performance of a single phase PWM inverter system using Insulated Gate Bipolar Transistors (IGBTs). For obtaining optimum voltage waveforms, the firing and commutation instants must be scheduled properly. The control circuit for such a system has been studied and implemented. Effect of the ratio of the carrier frequency to the reference frequency on the voltage harmonic content has been discussed and presented. It is well known that for inductive loads, snubber circuits become necessary. In the present paper, a method has been devised to calculate the proper values of the snubber circuit parameters. The validity of the devised method has been checked by using it with different operating conditions. Waveforms and harmonic spectrums for load voltage have been simulated and presented using SIMPLORER software

Distance Learning in Saudi Arabia: The Revolution in Higher Education and the Needs of the New Academic
Get PDFThe recent academic revolution within higher education in the past half of century brought about remarkable developments in delivery and pursuit of higher education. The most notable achievement was birth of distance learning that has resulted in unprecedented transformation both in diversity and scope. Distance learning in Saudi Arabia may be attributedto emergence of instructional and information technologies as well as their influence on learning and teaching. This new learning trend has enshrined mandatory equipping of teachers and students alike in educational institutions with fundamental skills and knowledge to cope with emerging challenges. The urgent quest for distance learning in KSA arose from massive growth in population vis-à-vis scarcity of resources and teachers in quality and quantity, plus the need to cut down financial costs. From as early as 1954, distance learning in KSA has evolved over three generational developments, namely correspondence study, multimediadistance teaching and interactive, web based instructions. It gained traction, interest and recognition among academics, academic institutions and students, although at a relatively slow pace. The author of this paper devours into history, growth and future of distance learning in KSA analyzing potential need and overall consequences on different stakeholders. The author further discusses the modern evolutions in distance learning such as e-learning and mlearning
REHA ERDEM SİNEMASI’NDA UZAM, ZAMAN BELLEK ÇERÇEVESİNDE “KOSMOS”FİLMİ
Get PDFSon dönem Türkiye Sineması’nın önemli yönetmenlerinden biri olan Reha Erdem’in ‘Kosmos’ adlı filminin uzam, zaman ve bellek açısından irdelenmesi bildirinin ana hedefidir. Bu çerçevede bir taraftan sinemanın uzam ve zamanla karşılıklı ilişkisi irdelenmekte diğer taraftan da sinemanın kendi uzam ve zamanını nasıl biçimlendirdiğine, nasıl dönüştürdüğüne değinilmektedir. Türkiye Sineması’ndaki dönemlerin bu iki kavram üzerinden kısa bir değerlendirmesinin ardından Reha Erdem sinemasının yarattığı atmosferdeki tüm uzam ve zamanın özellikleri incelenmektedir. Sinema aygıtı, günümüze kadar uzanan süreçte; tüm teknolojik, sosyo-ekonomik süreçlerden etkilenerek kendi yapısal özelliklerini deneyleyerek, sorgulayarak, dönüştürerek, yeniden tanımlayarak, eksiltip çoğaltarak sinema sanatı olarak kendini kanıtlamıştır. Bu süreç kesintisiz devam etmektedir. Tüm bu süreçler boyunca anlatı ve temsil yapıları uzam ve zamanın dönüşümlerini etkileyerek ve onlardan etkilenerek yeni biçemler geliştirmiştir. Tüm bu süreci şekillendirirken kendine özel öğeler (senaryo, kurgu, kamera, oyuncu, ses, müzik vb) üzerinden kendi anlatı kalıbını üretmektedir. Reha Erdem’in yarattığı atmosferin uzam –mekân, hareket, varlık/ beden- ve zaman kalıplarının sorgulanması yönetmenin sinemasal bakış açısını ortaya çıkaracaktır. Bu sorgulama ‘Kosmos’ üzerinden gerçekleştirilerek filmdeki atmosfer ve temalar üzerinden yönetmenin çok katmanlı anlatı yapısı çözümlenecektir
