Is spatial uncertainty necessary for the context specific proportion congruency effect?
Bozkurt, Özge; Mısırlısoy, Mine; Department of Psychology (2019)
Cognitive control is generally measured with the Stroop effect which is signified by slow responses in the incongruent (the word and color mismatch) items. The magnitude of the Stroop effect is modulated by experimental manipulations, for instance it is reduced by presenting items in mostly incongruent contexts as compared to mostly congruent contexts. The difference between the Stroop effects observed in these contexts is called the context specific proportion congruency (CSPC) effect. A large number of CS...
Is it necessary to apply the outlier detection for protein-protein interaction data?
Ayyıldız, Ezgi; Purutçuoğlu Gazi, Vilda (2018-01-01)
Objective: Outlier detection is a crucial problem in many fields. Although there are too many outlier detection methods in the literature, only a few methods suitable for dependent, sparse and high dimensional data structure. In this study, we perform various univariate and multivariate outlier detection methods as a pre-processing step before modeling the protein-protein interaction networks in order to investigate whether the outlier detection can improve the accuracy of the model. Material and Methods: W...
Is umbilicocerebral ratio better than cerebroplacental ratio for predicting adverse pregnancy and neonatal outcomes?

Objective A secondary analysis of the trial of randomized umbilical and fetal flow in Europe suggested that the umbilicocerebral ratio (UCR) provides better differentiation of neurodevelopmental outcome in the abnormal range compared with that of the cerebroplacental ratio (CPR).1 However, the reported superiority of UCR is controversial.2 This study aimed to compare the CPR and the UCR for predicting operative delivery for presumed fetal compromise and prolonged neonatal unit (NNU) admission in term fetus...
Is the use of GeoGebra advantageous in the process of argumentation?
Erkek, Ozlem; Işıksal Bostan, Mine (2015-01-01)
The purpose of this study was to investigate the advantages and disadvantages of using GeoGebra in an argumentative application. For this purpose, the data were collected from eight prospective elementary mathematics teachers via video recordings, reflection papers and interviews. Data were analyzed through qualitative data analysis methods. According to the results, making accurate drawings, creating confident justifications based on exact measurements, dragging objects to see relationships and saving time...
