Item Functional Connectivity In Rumination: A Systematic Review Of Magnetic Resonance Imaging Studies(Başkent Üniversitesi, 2024-02-18) Misir, Emre; Alici, Yasemin Hosgoren; Kocak, Orhan MuratIntroductionRumination, defined as intrusive and repetitive thoughts in response to negative emotions, uncertainty, and inconsistency between goal and current situation, is a significant risk factor for depressive disorders. The rumination literature presents diverse findings on functional connectivity and shows heterogeneity in research methods. This systematic review seeks to integrate these findings and provide readers diverse perspectives.MethodFor this purpose, the literature on functional connectivity in rumination was reviewed according to the PRISMA guidelines. Regional connectivity and network connectivity results were scrutinized according to the presence of depression, research methods, and type of rumination. After screening 492 articles, a total of 36 studies were included.ResultsThe results showed that increased connectivity of the default mode network (DMN) was consistently reported. Other important findings include alterations in the connectivity between the DMN and the frontoparietal network and the salience network (SN) and impaired regulatory function of the SN. Region-level connectivity studies consistently show that increased connectivity between the posterior cingulate cortex and the prefrontal cortex is associated with rumination, which may cause the loss of control of the frontoparietal network over self-referential processes. We have seen that the number of studies examining brooding and reflective rumination as separate dimensions are relatively limited. Although there are overlaps between the connectivity patterns of the two types of rumination in these studies, it can be thought that reflective rumination is more associated with more increased functional connectivity of the prefrontal cortex.ConclusionsAlthough there are many consistent functional connectivity outcomes associated with trait rumination, less is known about connectivity changes during state rumination. Relatively few studies have taken into account the subjective aspect of this thinking style. In order to better explain the relationship between rumination and depression, rumination induction studies during episode and remission periods of depression are needed.Item How Far are E-Scooters Healthy Transport?(2023) Tekes, Burcu; Musselwhite, Charles; 0000-0002-6601-1023; K-2947-2014Item Resistance to Common Insecticides and Mechanisms of Resistance in Aphis Pomi De Geer (Hemiptera: Aphididae), in Apple Orchards in Turkey(2023) Erdogan, Cem; Ozdem, Ayse; Alpkent, Yasin Nazim; Demiroz, Duygu; https://orcid.org/0000-0001-9537-3536; https://orcid.org/0000-0003-1501-1223; AAE-4306-2020; IZP-9920-2023The Green apple aphid, Aphis pomi de Geer (Hemiptera: Aphididae), is one of the most common and serious insect pests of apple orchards in Turkey. This species feeds on succulent tissue of trees, which can lead to leaf curling, stunting, distorted tip growth, black-sooty mold, and a vector of some plant viruses. Growers prefer to apply insecticide applications heavily to control the green apple aphid in commercial apple orchards. However, there have not been conducted any research study on insecticide resistance of A. pomi in Turkey. The resistance status of A. pomi populations collected from commercially apple orchards in the Central Anatolia region was investigated to: acetamiprid (neonicotinoid), the specific aphicide pirimicarb (carbamate), beta-cyfluthrin (synthetic pyrethroid), and chlorpyrifos-ethyl (organophosphate) insecticides. All populations were characterised for the first time using polyacrylamide gel electrophoresis to determine the esterase banding patterns. Biochemical assays revealed higher activity of total esterase. This is the first study conducted to determine glutathione S-transferase activity related to the insecticide resistance of A. pomi. It was determined that the resistance levels reached to 14.93 fold to acetamiprid, 3.74 fold to beta-cyfluthrin, 4.19 fold to chlorpyrifos-ethyl, and 4.33 fold to pirimicarb. The present study revealed neonicotinoid, organophosphate, carbamate, and pyrethroid resistance in A. pomi populations from the Central Anatolia Regions of Turkey. It also clearly showed that the enhanced esterase enzyme activity is the main resistance mechanism against carbamate pirimicarb resistance. The present study is the first insecticide resistance study on A. pomi for Turkey.Item Validation and Correlates of The Vicarious Embarrassment Scale(2014) Uysal, Ahmet; Akbas, Gulcin; Helvaci, Elif; Metin, Irem; HGT-9462-2022Vicarious embarrassment can be defined as embarrassment resulting from witnessing embarrassing behaviors of strangers. We developed a scale to measure individual differences in the tendency to experience vicarious embarrassment, and examined its association with related constructs. In Study 1, we found that vicarious embarrassment is associated positively with susceptibility to embarrassment, empathy, perspective-taking, and fear of negative evaluation, while it is associated negatively with self-esteem. In Study 2, we found that vicarious embarrassment is uniquely associated with embarrassment in response to a poor performance of a stranger on a TV show, independent of susceptibility to embarrassment, empathy, perspective-taking, and fear of negative evaluation. Although the limited literature on this topic focused on the role of empathy in this type of embarrassment, these findings suggest that there is more to vicarious embarrassment than empathy or perspective-taking.

A total of 603 high school students from Ankara Turkey, were selected using convenient sampling to participate in this study. During the course of this study, the FQS was first translated into Turkish and then its psychometric properties were examined. The construct validity of the FQS was tested using a confirmatory factor analysis (CFA). Before performing the CFA, the assumption of missing values, outliers, normality, and collineriaty were checked. According to the results, the 22-item FQS consisting of 5 dimensions had acceptable goodness of fit indexes (S-Bx(2)/df = 669.12/199, p = .00, RMSEA = .063, CFI = .97, GFI = .88, NNFI = .96). The Cronbach alpha coefficients of the subscales ranged between .66 and .86. The internal consistency for the entire scale was alpha = .85. In conclusion, an instrument consisting of 22 items and 5 subscales was prepared for future researchers.Item Longer Language Map of the Discoveries in Turku(2014) Eker, Suer; AAN-8254-2021Item On The Q - Seidel Matrix(2014) Firengiz, M. Cetin; Tuglu, Naim; https://orcid.org/0000-0002-9588-0295; HNQ-9215-2023Clarke and et. al recently introduced the q-Seidel matrix, and obtained some properties. In this article, we define a different form of q-Seidel matrix by a(n)(k) (x, q) = xq(n+2k-3)a(n)(k-1) (x, q)+an(k-1)(x, q)+a(n+1)(k-1) with k >= 1, n >= 0 for an initial sequence a(n)(0) (x, q) = a(n) (x, q). By using our definition, we obtain several properties of the q-analogues of generalized Fibonacci and Lucas polynomials.Item Mesenchymal Stem Cells Administered Intraperitoneally Have A Potent Effects on the Experimental Allergic Airway Disease(2015) Isik, S.; Adan Gokbulut, A.; Karaman, M.; Kiray, M.; Bagriyanik, H. A.; Caglayan Sozmen, S.; Kozanoglu, I; Karaman, O.; Baran, Y.; Uzuner, N.; 0000-0002-5268-1210; 0000-0003-4064-7637; AAE-1241-2021; H-7577-2013Item Early Maladaptive Schema Domains and Social Phobia Symptoms: Is There a Mediator Role of Emotion Regulation Difficulties?(2014) Eldogan, Dilay; Bariskin, ElifThe purpose of the study was to investigate the mediator role of emotion regulation difficulties on the relationship between early maladaptive schema domains and symptoms of social phobia. The sample included 240 university students. Liebowitz Social Anxiety Scale (LSAS), Beck Depression Inventory (BDI), Young Schema Questionaire-Short Form 3 (YSQ) and Difficulties in Emotion Regulation Scale (DERS) were administered. Analysis revealed that there is a mediator role of emotion regulation difficulties in the relation between Disengagement, Impaired Autonomy and Impaired Limits schema domains and the symptoms of social phobia. Strenghts, limitations and implications of the current study are discussed in the light of relevant research.Item Three Assessment Scales on Awareness: Psychological Mindedness, Integrative Self Knowledge and Toronto Trait Mindfulness Scales(2015) Sahin, Nesrin Hisli; Yeniceri, Zuhal; 0000-0001-9228-9961; F-8366-2010Awareness is a phenomenon which is increasingly attracting attention. However as a complex concept, it incorporates different dimensions. In spite of this increasing attention, there are very few instruments in the Turkish Language to be used in research aiming to conceptualize the construct. The purpose of the current study is to adapt three scales used in the related literature into Turkish, in order to study awareness with its several conceptual dimensions (psychological awareness, self awareness, and mindfulness). With this purpose in mind, the Psychological Mindedness Scale, the Integrative Self Awareness Scale, and Toronto Mindfulness Scale were translated into Turkish; and their psychometric properties, reliabilities and validities (construct validity and concurrent validity) were investigated. The results are interpreted in light of the related literature. The study revealed that these three scales can reliably and validly be used in studies on awareness.
