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 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 Differentiation of Memory Processing Stages and Effect of Demographic Variables with Alternative Scoring Approaches To The Rey Auditory Verbal Learning Test(2022) Karakas, Sirel; Bakar, Emel Erdogan; Dogutepe, Elvin; Can, Handan; Kaskati, Tolga; 35670663Background The Rey Auditory Verbal Learning Test (RAVLT) is the third most popular verbal memory test and the tenth most frequently used neuropsychological test. The original scoring system of RAVLT does not differentiate stages of memory processing, but a recently developed composite scoring system has this potential. The objectives were to compare the two systems in terms of their capacity to differentiate the stages of memory processing and to study the effect of demographic variables on the learning trials (T) of the Turkish form of RAVLT (T-RAVLT). Method The sample consisted of 600 Caucasian Turkic adults, who were categorized into three levels of age, three levels of education, and two levels of gender. Individual administration of T-RAVLT was performed using the standard procedures of RAVLT. Results The components in the exploratory factor analysis (EFA) and latent variables in the confirmatory factor analysis (CFA) of the original scores were consistent with sequentially ordered T-RAVLT stages. Demographic variables (age, education, and gender) affected performances in all of the learning trials. The composite scores revealed retrieval and retention as separate components, but these scores could not be predicted from the relevant T-RAVLT scores. Conclusions Findings recommend a combined utilization of the two scoring systems: The original system to provide scores on the performance at each stage of T-RAVLT and the combined system to provide separate scores on learning, retention, and retrieval, the three stages of memory processing. A selective effect of demographic variables on T1 was not observed, indicating a need for cross-cultural studies that are meticulously controlled for age and education.Item Aiding and Abetting Survival: Americanizing Robinson Crusoe through Adaptation(2022) Tutan, Defne ErsinDaniel Defoe's Robinson Crusoe (1719) has been insistently adapted to both the big screen and TV throughout the 20th century and well into the 21st, the earliest version dating back to 1902 and the most recent to 2016. Although a full list of all versions would be elusive and also redundant, almost 50 adaptations are readily available for viewing and/or for analysis. Moving away from the`fidelity' criticism in the earlier vein of adaptation studies and proceeding from the argument that all adaptations are essentially rewritings, alternative ways in which the source text may be reconstructed in an ultimately intertextual framework, this paper scrutinizes American screen adaptations of Robinson Crusoe, namely Robinson Crusoe on Mars (Dir. Byron Haskin, 1964), Lt. Robinson Crusoe, U.S.N. (Dir. Byron Paul, 1966), and Cast Away (Dir. Robert Zemeckis, 2000). Far from shedding new light on an almost-exhausted source text, these rewritings reflect more about their own discourses, relating to the historical and social contexts of their own making. In so doing, they `Americanize' Robinson Crusoe. As such, three centuries after its publication, Robinson Crusoe is still being repeatedly reinvented and reconstructed in film, and this analysis investigates the dialogical relations among these adaptations while, at the same time, emphasizing how every new adapted version of a work of literature aids and abets the survival of its source text.Item Investigation of the Effect of Melatonin Administration on Calpain-1 Expression and Atrophic Morphology in Atrophy of Mouse Myoblast Cell Line Exposed to Hydrogen Peroxide(2019) Karimi, Nazli; Kartal, Yasemin; Budak, Murat Timur; https://orcid.org/0000-0002-3534-6621; AAL-6138-2021Item Adultization and Blurring the Boundaries of Childhood in the Late Modern Era(2020) Orman, Turkan Firinci; 0000-0001-9137-0899; JBI-6684-2023Although the modern Western concept of childhood is rapidly disappearing in the age of late modernity, this study asserts that childhood (as it is lived) has not disappeared but has been transformed. An integrated approach to childhood is employed in order to go beyond binary oppositions such as the Global North versus the Global South and/or childhood versus childhoods. It is argued that children while constructing their childhoods are confronted with processes of individualisation and globalisation through which new forms of adultization have emerged as concepts of 'child consumerism' and 'child citizenship'. Beyond the opposing views involving the disappearance of childhood or its liberation, this study concludes that the concept of adultization can be used to problematise and analyse childhood in its current state.
