Okuma Çemberlerinin Okuduğunu Anlama ile Akıcı Okuma Üzerindeki Etkileri ve Okur Tepkileri: Bir Karma Yöntem Araştırması
The purpose of this research is to determine the effects of literature circles on reading comprehension and reading fluency and to reveal readers’ responses in this process. The model of the study was conducted in a mixed embedded experimental design. Literature circles method was applied in the quantitative dimension of the research, and reader responses to the books they read were revealed in the qualitative dimension Applications were carried out in two separate classes on the fourth grade of primary school one of which was the experimental group and the other was control group. Multiple choice reading comprehension test was used to determine the students’ reading comprehension and multidimensional fluency scale was used to evaluate reading fluency as data collection tools. Reader responses were reveaked through an open-ended questionnaire. In the study, it was conclueded that the literature circles method had positive effects in terms of reading comprehension. On the other hand, it hs been observed that the literature circles method has positive effects in terms of reading speed in the narrative and informative texts. According to the findings obtained from the reader responses to the books they read, it is understood that the answers of the students to the books they read were mostly reader-centered in the qualitative dimension of the research. From the first literature circle to the last literature circle application, it seen that the reader-centered responses increased and text-centered responses decreased in each literature circle during the research.Bu araştırmanın amacı, okuma çemberleri yönteminin okuduğunu anlama ile akıcı okuma üzerindeki etkilerinin belirlenmesi ve bu süreçte okur tepkilerinin ortaya çıkarılmasıdır. Araştırmanın modeli karma gömülü deneysel desen olarak tasarlanmıştır. Araştırmanın nicel boyutunda okuma çemberleri yöntemi uygulanmış, nitel boyutunda ise öğrencilerin okudukları kitaplara yönelik okur tepkileri ortaya çıkarılmıştır. Uygulamalar ilkokul dördüncü sınıflarda biri deney diğeri kontrol grubu olmak üzere iki sınıfta yürütülmüştür. Veri toplama araçları olarak öğrencilerin okuduğunu anlamalarını belirlemede çoktan seçmeli okuduğunu anlama testi ile akıcı okumanın değerlendirilmesinde çok boyutlu akıcılık ölçeği kullanılmıştır. Okur tepkileri ise açık uçlu anket formu aracılığıyla ortaya çıkarılmıştır. Araştırmada, okuma çemberleri yönteminin, okuduğunu anlama açısından olumlu etkileri olduğu sonucuna ulaşılmıştır. Öte yandan okuma çemberleri yönteminin, hikâye edici ve bilgi verici metinlerde okuma hızları bakımından olumlu etkilerinin olduğu da görülmüştür. Araştırmanın nitel boyutunda öğrencilerin okudukları kitaplara yönelik okur tepkilerinden elde edilen bulgulara göre öğrencilerin okudukları kitaplara yönelik yanıtlarının çoğunlukla okur merkezli olarak ortaya çıktığı anlaşılmaktadır. Araştırma süresince birinci okuma çemberinden sonuncu okuma çemberi uygulamasına kadar öğrencilerin her okuma çemberinde okur merkezli yanıtlarının arttığı, metin merkezli yanıtlarının ise azaldığı görülmektedir
What role do language learning mindsets play in English Medium Instruction? A comparison of Engineering and Business Administration in Turkey.
This article explores the relationship between Turkish undergraduate students’ language learning mindsets, English language achievement, and English medium instruction (EMI) academic success. Student test score data on an EMI course and an English language course were collected from fourth year students studying mechatronics engineering (n = 68) and business administration (n = 75) at a public university. Students also responded to the Language Learning Mindsets Inventory (Lou & Noels, 2019). Regression analyses revealed that both incremental (positively) and entity (negatively) mindsets predicted academic success in engineering. Neither mindset was a statistically significant predictor of mechatronics engineering students’ English language achievement. Business administration students’ academic success and English language achievement were both statistically significantly predicted by both incremental (positively) and entity (negatively) mindsets. These results are discussed according to discipline-based differences in EMI courses and pedagogical implications are explored
Explicit solutions of generalized nonlinear Boussinesq equations
By considering the Adomian decomposition scheme, we
solve a generalized Boussinesq equation. The method does not need
linearization or weak nonlinearly assumptions. By using this
scheme, the solutions are calculated in the form of a convergent
power series with easily computable components. The decomposition
series analytic solution of the problem is quickly obtained by
observing the existence of the self-canceling “noise” terms
where sum of components vanishes in the limit
An explicit solution of coupled viscous Burgers' equation by the decomposition method
We consider a coupled system of viscous Burgers' equations with
appropriate initial values using the decomposition method. In this
method, the solution is calculated in the form of a convergent power
series with easily computable components. The method does not need
linearization, weak nonlinearity assumptions or perturbation theory.
The decomposition series solution of the problem is quickly obtained by
observing the existence of the self-canceling noise terms where
the sum of components vanishes in the limit
Development of a WEB application

cellular machinery, target mRNAs for silencing by binding generally to their 3’ UTR
sequences via partial base complementation. Thus, microRNAs with similar
sequences also might exhibit expression and/or functional similarities. In this study, a
modular tool, mESAdb (http://konulab.fen.bilkent.edu.tr/mirna/), was developed
allowing for multivariate analysis of sequences and expression of microRNAs from
multiple taxa. Its framework comprises PHP, JavaScript, packages in the R language,
and a database storing mature microRNA sequences along with microRNA targets
and selected expression data sets for human, mouse and zebrafish. mESAdb allows
for: (i) mining of microRNA expression data sets for subsets of microRNAs selected
manually or by a sequence motif; (ii) pair-wise multivariate analysis of expression
data sets within and between taxa; and (iii) association of microRNA subsets with
annotation databases, HuGE Navigator, KEGG and GO. mESAdb also permits user
specified dataset upload for these analyses. Herein, utility of mESAdb was illustrated
using different datasets and case studies. First, it was shown that microRNAs
carrying the embryonic stem cell specific seed sequence, ‘AAGTGC’, were able to
discriminate between normal and tumor tissues from hepatocellular carcinoma
patients using dataset GSE10694. Second, mRNA targets of a set of liver specific
microRNAs were annotated with human diseases based on HuGE Navigator. Third,
the similarity between mouse and human tissue specificity of a given set of microRNAs was demonstrated. Forth, CHRNA5 targeting microRNAs were
associated with estrogen receptor status in breast cancer using dataset GSE15885.
Finally, a related tool under development for mRNA arrays planned for integration
with mESAdb was presented.Kaya, Koray DoğanPh.D
Cognitive performance in young and middle-aged adults with migraine: Investigating the correlation with white matter hyperintensities and psychological symptoms
Introduction
This study aimed to evaluate the cognitive performance of migraine patients with (MwA) and without aura (MwoA) and investigate the correlation of white matter hyperintensities (WMHs) and psychological symptoms with their cognitive test scores.
Material and methods
Hundred migraine patients aged 20–55 years and 80 healthy volunteers with similar age, sex, and education level were enrolled. The total Montreal Cognitive Assessment (MoCA) scores were compared by age, sex, presence of aura, migraine duration, attack frequency, pain localization, presence and number of WMHs, and the scores of the Beck Depression Inventory and the Beck Anxiety Inventory (BAI).
Results
Forty-seven (47%) patients had MwA and 53 (53%) had MwoA. The performance of the MwA patients was significantly poorer than that of the MwoA patients and the healthy subjects on the MoCA scales. In particular, the results revealed lower scores in the subscales regarding visuospatial/executive functions, naming, memory, attention, and abstraction in MwA patients than in the MwoA patients. Compared to healthy controls, more number of migraine patients had WMHs. The presence and number of WMHs had no significant correlation with the MoCA scores of the migraine patients. There was a significant correlation of the BAI and BDI scores with the total MoCA scores considering all migraine patients.
Conclusions
This study suggested that MwA may be associated with low cognitive performance which was correlated with depression and anxiety but not with WMHs. Further, longitudinal studies for assessing the relationship between WMHs, cognitive functions, and migraine, and for establishing the causality are warranted
Childhood Multisystem Inflammatory Syndrome With Prominent Neurological Involvement
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
is the pathogen that causes coronavirus disease 2019 (COVID-19),
which was declared a pandemic on March 11, 2020, by the World
Health Organization.1 The difference in clinical severity between
adults and children may be due to the differences in renin-
angiotensin system receptors and altered inflammatory pathogen
responses.
Depressive Symptoms in a General Population: Associations with Obesity, Inflammation, and Blood Pressure
To determine whether obesity, inflammation, or conventional risk factors are related to depressive symptoms (DeprSy) in the general population. Responses to 3 questions served to assess sense of depression. Body mass index (BMI), C-reactive protein (CRP), and other epidemiologic data of participants were available. In 1940, individuals who consulted a psychiatrist in the preceding year, or felt depressed (together DeprSy), 248 were female. Logistic regressions for adjusted associations of BMI with DeprSy were not significant as was serum CRP level. Diabetes and, in men, fasting glucose concentrations were associated with DeprSy. Systolic blood pressure (SBP) was robustly inversely associated with DeprSy in diverse models at ORs of 0.74 (95%CI 0.63; 0.89) independent of confounders, including antihypertensive and lipid-lowering medication. The use of antidepressants could not explain the reduced BP. Women are predisposed to depression with which, not BMI and CRP, but SBP is inversely associated. Anti-inflammatory substances produced in depressed persons might explain the slightly lower BP
Zygomatic abscess with temporomandibular joint effusion complicating acute otitis media
WOS: 000386676300007The incidences of extracranial and intracranial complications of acute otitis media (AOM) in children have markedly decreased in the postantibiotic era.
