Effectuality of Barrier Height Inhomogeneity on the Current-Voltage-Temperature Characteristics of Metal Semiconductor Structures with CdZnO Interlayer
No full textTaşçıoğlu, İlke (Arel Author)Current-conduction/transport mechanisms (CCMs or CTMs) through barrier and barrier height (BH) formation in the Al/(CdZnO)/p-Si/Al diodes, which were prepared by the sol-gel method, were examined in the range of 110-380 K. The decrease of zero-bias BH (Phi(Bo)) and increase of ideality factor (n) with decreasing temperature were observed. The classic Richardson plot indicated two distinct linear regions that correspond to low and high temperature range (LTR and HTR), respectively. Contrary to this, the acquired Richardson constant value (A*) was much lower than its theoretical value (32 A cm(-2) K-2). Such abnormal behavior of the Phi(Bo), n and A* was attributed to the evidence of the barrier inhomogeneities, especially at low temperature. Therefore, the Phi(Bo-)n, Phi(Bo) and (n(-1) - n) versus q/2kT plots were sketched to acquire significant clues for the Gaussian distribution (GD) of the BHs at rectifier contact area with the mean BH ((Phi) over bar (Bo)) and standard deviation (sigma(so)), which also have two linear parts with distinct slopes. (Phi) over bar and sigma(so) were calculated from the slope and intercept of Phi(Bo) versus q/2kT plot as 0.802 eV and 0.066 V for LTR, 1.043 eV and 0.106 V for HTR, respectively. The (Phi) over bar (Bo) and A* were acquired by utilizing the sigma(so) values and using the Richardson plot as 0.626 eV and 14.26 A cm(-2) K-2 for LTR and 1.021 eV and 32.53 A cm(-2) K-2 for HTR, respectively. Thus, the I-V-T characteristics of the Al/(CdZnO)/p-Si/Al diodes at forward biases were successfully elucidated by the double-GD of BHs with mean BHs of 0.626 eV and 1.021 eV, respectively
Precision Study of eta ' -> gamma pi(+) pi(-) Decay Dynamics
No full textUsing a low background data sample of 9.7×105 J/?????, ?????+?- events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at BEPCII, the decay dynamics of ?????+?- are studied with both model-dependent and model-independent approaches. The contributions of ? and the ?(770)-? interference are observed for the first time in the decays ?????+?- in both approaches. Additionally, a contribution from the box anomaly or the ?(1450) resonance is required in the model-dependent approach, while the process specific part of the decay amplitude is determined in the model-independent approach. © 2018 authors.

Lateralization of Neurobiological Response in Adolescents with Post-Traumatic Stress Disorder Related to Severe Childhood Sexual Abuse: the Tri-Modal Reaction (T-MR) Model of Protection
No full textKoşe Demiray, Çiğdem (Arel Author)This study inquires into neurobiological response to stress and its clinical correlates among adolescents with post-traumatic stress disorder (PTSD). Structural magnetic resonance imaging (MRI) measures of cerebral anatomy were carried out on 23 female adolescents with PTSD related to severe childhood sexual abuse and 21 matched healthy controls. Clinician Administered PTSD Scale for Children and Adolescents, Adolescent Dissociative Experiences Scale, Childhood Trauma Questionnaire, Schedule for Affective Disorders and Schizophrenia for School Age Children, Beck Depression Scale, and a set of neuro-cognitive tests were administered to all participants. Compared to controls, PTSD group bilaterally had smaller amygdala, hippocampus, anterior cingulate, and thinner prefrontal cortex but normal thalamus. Further analyses within the PTSD group suggested an association between symptoms of PTSD and sizes of right brain structures including smaller amygdala but larger hippocampus and anterior cingulate. Thinner right prefrontal cortex and larger right thalamus seemed to be related to denial and response prevention, respectively. Being related to both hemispheres, dissociative amnesia was negatively associated with proportion of the right amygdala to right thalamus and to both left and right prefrontal cortex. Suggesting a neuro-protective effect against traumatic stress at least through adolescence, depersonalization-derealization and identity alteration were correlated with thicker left prefrontal cortex. Unlike the lateralization within PTSD group, correlations between regions of interest were rather symmetrical in controls. The graded response to stress seemed to be aimed at mental protection by lateralization of brain functions and possibly diminished connection between two hemispheres. A Tri-Modal Reaction (T-MR) Model of protection is proposed
Current Tendencies in Postgraduate Theses Written in the Field of Art Education in Turkey
No full text#nofulltext# --- Peker, Huriye Sevinç (Arel Author)The education activities that are performed for the purpose of expressing thoughts and impressions and raise the talent and creativity to an aesthetic level are expressed as art education. The purpose of this study is to examine the postgraduate theses conducted on "art education" in Turkey. The study was conducted as a qualitative study and the data were collected through the document analysis method. The research data were analyzed through content analysis. 74 postgraduate theses on art education that were searched by the term "Art Education" on YOK (Council of Higher Education) National Thesis Center database were accessed. 54 of the 74 postgraduate theses are master's theses and 20 of them are PhD dissertations. Among these theses, in total 48 theses were examined as 12 PhD dissertations and 36 master's theses. For the purpose of examining the theses accessed, the "Thesis Examination Form" was developed by the researchers towards the objective of the study. In this context, all of the open access -postgraduate theses that were conducted on the field of art education between the years of 2012-2017 were grouped from various aspects. The general assessments of the theses were made according to the institutes that they are affiliated with, years, universities, study groups, research models and data collection tools. In terms of the data analysis, frequency (f) was utilized and the findings were presented on graphs. According to the obtained data, most of the theses (11) were conducted on the years between 2014 and 2015. Between the years of 2012 and 2017, Gazi University is in the first place among the Turkish universities with the number of theses conducted in the field of art education. While qualitative methods (25) were preferred in the theses predominantly, quantitative methods followed the given situation. Almost all of the theses (%90) were conducted in an Institute of Education Sciences. Furthermore, the most frequently used data collection tool was a document/archive. Moreover, while the studies were conducted towards students they were designed as document oriented, and in the level of higher education, they were designed as prospective teacher/undergraduate student -oriented

Dikkat eksikliği hiperaktivite bozukluğu ve omega-3 yağ asidi takviyesi: Sistematik bir derleme
No full textObjectives: The current study aims to explore (1) the relationship among alexithymia, emotional regulation, and various psychological symptoms factors; (2) the mediating role of emotion regulation strategies in the relationship among alexithymia and psychological symptoms; and (3) whether individuals with alexithymia high and low scores differ in psychological symptoms and emotional regulation. Method: In this study that consists of 319 university students reached through convenience sampling method, a cross sectional non-experimental design is used. A demographic information form, the Toronto Alexithymia Scale (TAS-20), Brief Symptom Inventory (BSI) and Emotion Regulation Scale (ER) were used for data collection. Results: TAS-20 Scores were moderately positively correlated with all factors of BSI and the BSI-General Severity Index (GSI) and the ER-suppression subscale while negatively correlated with the ER- cognitive reappraisal factor. Further analysis showed that ER-suppression subscale mediated the relationship between alexithymia and the BSI-GSI while ER-cognitive reappraisal subscale did not mediate it. Finally, a series of Mann-Whitney U tests indicated that individuals with high levels of alexithymia differed from those with low levels in all study variables. Conclusion: The results show that ER-suppression subscale has a mediating role between alexithymia and psychological symptoms as well as that alexithymia and emotional regulation are effective factors for predicting psychological symptoms. Finally, the findings imply that emotion regulation is associated with alexithymia and psychological symptoms and contribute to the development these factors. © 2019, Istanbul Universitesi.
