Metacognitions and emotion recognition in Internet Gaming Disorder among adolescents

© 2020 The Author(s) Internet Gaming Disorder (IGD) is associated with considerable psychological distress in adolescents. However, studies which strive to shed light on the developmental background of IGD are still sparse. We aimed to examine the role of metacognitions and emotion recognition in predicting IGD during the early adolescence period. Four hundred and seventy-seven secondary school students were recruited for the study. Participants completed the Internet Gaming Disorder Test (IGDT), the Metacognitions Questionnaire for Children (MCQ-C), and the Children's Version of Reading the Mind in the Eye Test (RMET). Correlation analyses indicated that three factors of the MCQ-C (positive meta-worry, negative meta-worry, and superstition, punishment, and responsibility) and its total score were positively correlated with the majority of factors of the IGDT. The negative factor of the RMET was positively correlated with the salience, tolerance, and relapse factors and total score of the IGDT. Daily internet use was positively correlated with all factors of the IGDT and its total score. Hierarchical regression analyses indicated that daily internet use and metacognitions (in different combinations) were significant independent predictors of IGDT factors and its total score, and that the negative factor of the RMET was a significant independent predictor of the salience and tolerance factors of IGDT and its total score. The implications of these findings are discussed

The Combined Contribution of Fear and Perceived Danger of COVID-19 and Metacognitions to Anxiety Levels during the COVID-19 Pandemic.

Despite a wide base of research suggesting a major role for dysfunctional metacognitions in contributing to anxiety, their role in explaining psychological distress in the context of the COVID-19 pandemic remains unclear. In this study we investigated whether metacognitions would predict anxiety, while controlling for fear and perceived danger of COVID-19. A total of 862 individuals were included in this study. Participants completed sociodemographic questions, emotional state questions relating to COVID-19, the Metacognitions Questionnaire-30, and the Generalized Anxiety Disorder-7. Results showed that both negative beliefs about thoughts concerning uncontrollability and danger, and cognitive self-consciousness were significant predictors of anxiety beyond the fear and perceived danger of COVID-19. Future studies involving clinical populations are needed to investigate the longer-term impact of metacognitions in the maintenance and exacerbation of anxiety associated with the fear and perceived danger of COVID-19

Anxiety in Visually Impaired Students about the Future

The aim of this study is to determine the anxiety level that visually impaired students may have for the future when planning their profession. Anxiety is defined as excessive level fear and worry about real or imaginary situations. So the excessive worry can affect the ability to act to solve a problem. This study is a case study based on the semi-structured interviews. The study group consists of six 8th grade students with visual impairment. The aim of selecting students with visual impairment as a sample group is to determine the individuals who are aware that education is an important for their future plans but at the same time aware that the barriers created by society have greater impact on their the socialization. As a result, visually impaired individuals are willing to be part of the society, but the created obstacles cause anxiety in many different ways as they constitute their futures. This situation negatively affects their motivation and academic performance, and diminishes the importance of education for them as well

Effect of Oestradiol Administration on Rat Submandibular Gland after Ovariectomized Period

In this study, we aimed to investigate exogen estrogen on submandibulargland of adult ovariectomized rats. To this end, thirty-six virgin female WistarAlbino rats were used and were divided into three equal groups. Sham groupsreceived no treatment, all animals in the other two groups were bilaterallyovariectomized. Control groups was designated bilaterally ovariectomized andoestradiol was given application groups.Following the applications all animals were sacrified,then submandibulargland was excised and paraffin wax. Paraffin sections, obtained by routinehistologic methods, were cut at 5μm and stained with Hematoxilen-Eozin. Thestained sections were later evaluated under a light microscopy.Histological studies indicated that, after oestrogen deficiency period, theglandular parenchyma and stroma was destroyed. When oestrogen was givenexogenously, it was seen that after ovariectomy, the gland was partially improved.These data demonstrate that oestrogen deficiency play a role in rat of thesubmandibular gland. Exogenous oestrogen leads to partial improvement andoestrogen deficiency doesnt lead to changes of the gland. Exogenous oestrogendoes not completely prevent submandibular gland structur

Effects of humidity level and IBA dose application on the softwood top cuttings of white mulberry (Morus alba L.) and black mulberry (Morus nigra L.) types

In this research, the effects of 85-90% relative humidity and ındol-3-butyric acid (IBA) doses on softwood top cuttings of two black mulberry (Types 1 and 2) and one white mulberry (Type 3) types were studied. Cuttings were taken from early June (14 Haziran) and applied to the different IBA doses (0, 1000, 2000, 3000 and 4000 ppm). Cuttings were planted in pumice medium under misting system in the greenhouse for 48 days in order to root. The highest rooting percentage was determined from Type 1 (black mulberry) in 2000 and 3000 ppm IBA doses application (100%). The lowest one was control group from Type 2 (black mulberry) which was not rooted. Acording to increase liveliness of the cuttings, rooting percentage increased. Nearly all of the living cuttings were rooted. The highest ratio of cutting callus formation was found to be 2000 and 3000 ppm IBA doses (100%) from Type 1; the lowest one was determined control group of Types 2 and 3 (0.00%). The highest rooting area lenght was found from Type 3 (2.00 cm) and Type 1 (1.92 cm); the lowest one was control group of Type 2 (0.00 cm). With respect to root numbers, the highest value was found from Type 3 (21.73 number/cutting) and Type1 (16.42 number/cutting); the lowest one was control group of Type 2 (0.00 number/cutting). The longest root was determined from 3000 ppm IBA dose of Type 1 (11.23 cm); the highest root branching value was found from Type 3 in 3000 ppm IBA dose (16.20 number/cutting) application

Adaptive human force scaling via admittance control for physical human-robot interaction

The goal of this article is to design an admittance controller for a robot to adaptively change its contribution to a collaborative manipulation task executed with a human partner to improve the task performance. This has been achieved by adaptive scaling of human force based on her/his movement intention while paying attention to the requirements of different task phases. In our approach, movement intentions of human are estimated from measured human force and velocity of manipulated object, and converted to a quantitative value using a fuzzy logic scheme. This value is then utilized as a variable gain in an admittance controller to adaptively adjust the contribution of robot to the task without changing the admittance time constant. We demonstrate the benefits of the proposed approach by a pHRI experiment utilizing Fitts’ reaching movement task. The results of the experiment show that there is a) an optimum admittance time constant maximizing the human force amplification and b) a desirable admittance gain profile which leads to a more effective co-manipulation in terms of overall task performance.WOS:000731146900006Scopus - Affiliation ID: 60105072Q2ArticleUluslararası işbirliği ile yapılan - EVETOctober2021YÖK - 2021-22Eki

Unbounded p-Convergence in Lattice-Normed Vector Lattices

A net xα in a lattice-normed vector lattice (X, p, E) is unbounded p-convergent to x ∈ X if p(| xα− x| ∧ u) → o 0 for every u ∈ X+. This convergence has been investigated recently for (X, p, E) = (X, |·|, X) under the name of uo-convergence, for (X, p, E) = (X, ‖·‖, ℝ) under the name of un-convergence, and also for (X, p, ℝX ′) , where p(x)[f]:= |f|(|x|), under the name uaw-convergence. In this paper we study general properties of the unbounded p-convergence.Article Pre-prin

Fonksiyonel Kademelendirilmiş Sandviç Plakaların Balistik Darbe Yükü Altındaki Davranışı Üzerinde Farklı Seramik Bileşenlerinin

Konferans Bildirisi -- Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2015Conference Paper -- Theoretical and Applied Mechanical Turkish National Committee, 2015Günümüzde de gelişen tehditler karşısında daha etkin balistik koruma sağlayacak hafif ve yüksek performanslı zırhların geliştirilmesi kritik bir ihtiyaç haline gelmiş ve bu sahadaki yeni malzeme arayışları seramik ön yüzlü kompozit zırhları ön plana çıkarmıştır. Katmanlı yapıya sahip bu plakalar yüksek mukavemetleri ve yüksek rijitlikleri nedeniyle balistik sistemlerde yaygın olarak kullanılırlar. Ancak, katmanlardaki malzeme özelliklerinin ani olarak değişmesi nedeniyle ara yüzeylerde yüksek gerilmeler meydana gelir ve bu gerilmeler de katmanlar arasında ayrılmalara (delaminasyon) neden olur. Bu olumsuz etkiler fonksiyonel kademelendirilmiş malzemeler (FGM) kullanılarak azaltılabilir ya da ortadan kaldırılabilir. Bu çalışma ile farklı seramik bileşenlere sahip fonksiyonel kademelendirilmiş sandviç plakalarda balistik darbe yükleme altında meydana gelen hasar mekanizmaları ve deformasyonları deneysel olarak incelenmiştir.Today, the development of high-performance and light armors has become a critical requirement against emerging threats. The research for new materials in this field has brought ceramic-faced composite armors to the forefront. Layered composite structures are widely used in ballistic systems due to their high strength and high stiffness. An abrupt change in their material properties across an interface between discrete materials introduces large interlaminar stresses that could cause delamination. One way to overcome this adverse effect is to use a functionally graded material (FGM). The purpose of this study is to determine damage and deformation mechanisms of functionally graded sandwich plates, which have different ceramic components, under ballistic impact loads

Tumour suppressor PTEN enhanced enzyme activity of GPx, SOD and catalase by suppression of PI3K/AKT pathway in non-small cell lung cancer cell lines

Phosphates and tensin homologue deleted on chromosome 10 (PTEN) is a tumour suppressor gene which dephosphorilates phosphoinositol 3,4,5 triphosphates. Therefore PTEN can regulate PI3K/AKT pathway in cells. Because of promoter methylation or gene deletion, PTEN expression is commonly decreased or lost in non-small cell lung cancer (NSCLC) cell lines. Therefore, we hypothesized that PTEN could regulate the activity of superoxide dismutase (CuZnSOD), glutathione peroxidase (GPx) and catalase. We first recreated PTENwt, G129R and G129E expressions in lung cell lines, in which endogenous PTEN expression was not detected. Then, we showed that PTEN could suppress AKT activity by its lipid phosphatase domain. We then examined the effect of recreated PTEN expressions in NSCLC cells. While PTENwt expression caused enhanced activity of SOD, GPx and catalase in transfected cells lines, neither G129R nor G129E expression effected enzyme activities. These results suggest that PTEN can up-regulate SOD, GPx and catalase activity by inhibition of PI3K/AKT pathway in NSCLC cell lines. © 2013 Informa UK, Ltd
