Understanding patterns for smartphone addiction: Age, sleep duration, social network use and fear of missing out

The aim of this study is to examine high school students and uncover the relationships between Smartphone Addiction levels and certain factors such as (a) Fear of Missing Out (FoMO) (b) Social Networking Site (SNS) usage habits (using smartphones), (c) age, d) sleep duration and (e) duration of smartphone ownership. The study group consists of 161 students from two public high schools in Turkey. Two different scales were employed for data collection; namely, the Smartphone Addiction Scale and FoMO Scale. Based on a cross-sectional research method, this qualitative study makes use of Pearson Correlation and Stepwise Multiple Regression statistical tests. Findings have shown positive correlations interpreted as Smartphone Addiction increasing with greater student age, daily duration of SNS use on smartphones, duration of smartphone ownership, and Fear of Missing Out. In addition, there exists negative-correlation between smartphone addiction and sleep duration, as well as frequency of SNS use on smartphones. Last but not least, it has been shown that FoMO, daily duration of SNSs use on smartphone and duration of smartphone ownership predict smartphone addiction, with the FoMO variable being the strongest predictor. © 2018 SciencePark Research, Organization & Counseling.

Mobile learning according to students of Computer Engineering and Computer Education: A comparison of attitudes

Mobile learning has started to perform an increasingly significant role in improving learning outcomes in education. Successful and efficient implementation of m-learning in higher education, as with all educational levels, depends on users' acceptance of this technology. This study focuses on investigating the attitudes of undergraduate students of Computer Engineering (CENG) and Computer Education and Instructional Technology (CEIT) departments in a Turkish public university towards m-learning from three perspectives; gender, area of study, and mobile device ownership. Using a correlational survey method, a Mobile Learning Attitude Scale (MLAS) was administered to 531 students, analysis of which revealed a positive attitude to m-learning in general. A further investigation of the aforementioned three variables showed a more positive attitude for female students in terms of usability, for CEIT students in terms of advantages, usability and independence, and for those owning a mobile device in terms of usability. An important implication from the findings, among others, is supplementing Computer Engineering curriculum with elective courses on the fundamentals of mobile learning, and/or the design and development of m-learning software, so as to create, in the long run, more specialized and complementary teams comprised of trained CENG and CEIT graduates in m-learning sector

The relationship between nomophobia and loneliness among Turkish adolescents

This study looks into the relationship between nomophobia and loneliness, and the effects of smartphone and mobile internet use among adolescents. A total of 301 adolescents were employed for the study and the data were collected via Nomophobia (NMP-Q) and UCLA Loneliness Short-Form (ULS-8) Scales. The study was conducted in a relational survey model using descriptive statistics, ANOVA, Pearson correlation, and linear regression. According to the findings the levels of nomophobic behaviors of adolescents were at a moderate level. While there was not a statistically significant correlation in terms of the duration of smartphone ownership and monthly mobile internet GSM quota, a significant difference was found in terms of the duration of mobile internet ownership, the duration of daily mobile internet use, and daily smartphone checking time. Finally, there was a statistically significant relationship between nomophobia and loneliness, and it can be ascertained that loneliness of adolescents predicts their nomophobia levels to a certain extent. © 2018, International Journal of Research in Education and Science.

Relationship between nomophobia and fear of missing out among Turkish university students

To the literature, it is seen that there are some studies demonstrating the relationship between FOMO and problematic smartphone use, or FOMO and smartphone addiction. However, no study has yet been found that explains the relationship between nomophobia and FOMO. Therefore, the aim of this study is to examine the effect of FOMO on nomophobia by investigating the relation between nomophobia and FOMO. No mobile phobia, i.e., nomophobia, is about a contemporary fear of not having a chance to communicate via mobile phone, while Fear of Missing Out, i.e., FOMO, is known to be correlated with the problematic use of social networking sites (SNSs). This descriptive study is a correlational study adopting a correlational survey model. The data were collected from a convenient sample of 538 university students via nomophobia questionnaire (NMP-Q) and FOMO scales as data collection tools. The results show that a positive moderate level of the relationship was found between Nomophobia and FOMO levels. © 2018 SciencePark Research, Organization & Counseling. All rights reserved

The development of the online player type scale: Construct validity and reliability testing

The present study outlines the development of the Online Player Type Scale (OPTS) utilizing a motivational taxonomy developed. This taxonomy was comprehensively reviewed to create scale items, and the conceptual framework of the scale was defined. The study group was comprised of 1,479 students attending grades 5 to 8 of a private school. A purposive sampling method was used to recruit the study group, and playing any videogame frequently was the criterion to be included in the sample. The construct validity and reliability testing showed the OPTS comprised four factors: achievement-oriented (ACH), socialization-oriented (SOC), exploration-oriented (EXP), and competition-oriented (COMP). The Cronbach alpha internal consistency coefficients and composite reliability coefficients were 0.89 and 0.99 for KIL, 0.83 and 0.98 for EXP, 0.83 and 0.98 for SOC, and 0.94 and 0.99 for ACH. It is concluded that the Online Player Type Scale is a valid and reliable instrument for assessing gaming motivation. Copyright © 2020, IGI Global

Trichoderma atroviride ve Trichoderma citrinoviride’nin büyüme profilleri ve biyogübre ile biokontrol ajanı olarak potansiyellerinin değerlendirilmesi

Background: Two Trichoderma species (T. atroviride and T. citrinoviride) were evaluated for their potential to have Trichoderma-based biological control agent and biofertilizer properties. Materials and Methods: Eight Trichoderma spp. were identified by molecular methods. The mycoparasitic activities against different phytopathogenic fungi and their capacity to produce extracellular lytic enzymes were investigated. Furthermore, indole-3-acetic acid production and phosphate solubilization capabilities of Trichoderma spp. were evaluated together with the effect of some physical parameters and different carbon:nitrogen sources on mycelial growth and conidium production. Results and Discussion: All strains exhibited lytic enzymes and indole-3 acetic acid production as well as phosphate solubility characteristics. Trichoderma citrinoviride demostrated more mycoparasitic activity against Fusarium oxysporium than T. atroviride whereas T. atroviride was found more effective against Rhizoctonia solani. In particular, at lower temperatures, conidium production of T. atroviride strains were significantly higher than T. citrinoviride strains. Both strains grew well on all carbon sources tested. The effect of organic nitrogen sources on growth were notably higher than inorganic nitrogen sources. Conclusion: The results provided valuable insight in both the highest mycelial growth and conidia production conditions of these cultures for further similar studies related to development of Trichoderma-based new commercial biological control and biofertilizer formulations in different agro-climatic regions. © 2020 De Gruyter.

Investigation of nomophobia and smartphone addiction predictors among adolescents in Turkey: Demographic variables and academic performance

Most individuals spend a great amount of time on their smartphones. The intense usage of smartphones leads to some physical symptoms, good and bad feelings, pathological addiction, depression, symptoms such as fear-anxiety, productivity and low academic achievement. For this reason, prevention activities must be prioritized when dealing with the intense and uncontrolled usage of smartphones. The aim of this study is to determine nomophobia levels and smartphone addiction among 12-18 age group secondary and high school students and to investigate the demographic and academic variables predicting these levels. Designed with a relational model, the population of this research consists of 612 students studying at all levels of secondary school and high school. Personal information form and two different scales were used in the research. Descriptive analyses and hierarchical linear multiple regression analysis were used in the analysis of the data obtained by means of data collection in the research. As a result of the research, there is a significant relationship between smartphone addiction and nomophobia. In this study, Model 4 has been identified to be the most important predictor of smartphone addiction and nomophobia. In Model 4, variables related to smartphone usage are included in the analysis. Recommendations have been made according to the results of the study. (C) 2018 Western Social Science Association. Published by Elsevier Inc. All rights reserved
