18 - Turkey
(Cambridge University Press, 2020) Diner,C.
Each of these chapters contains a case study of a couple from the relevant country. Each includes a description of the everyday life of the couple with respect to the division of housework and childcare, a recounting of the history of their relationship and how it became equal, a discussion of how they balance paid work and family, and an analysis of the factors that facilitate their equality. Those factors include their conviction in gender equality, their rejection of essentialist beliefs, their familism, and their socialization in their families of origin. By showing how and why they undo gender, these couples provide lessons on how equality at home can be achieved. © Cambridge University Press 2020
50. Complete acquisition in the heritage language: Evidence from indefiniteness in Turkish
(2023) Yılmaz, Gülsen; Sauermann, Antje
This study investigates whether adult Turkish heritage speakers are able to refer to entities in discourse as required by semantic contexts. The focus is on the contrasting properties of Turkish (L1) and German (L2) with respect to semantics of indefiniteness, i.e., specificity and partitivity. Turkish morphologically distinguishes between specific/nonspecific and partitive/nonpartitive contexts on the indefinite direct object while German does not. We hypothesized that the Turkish heritage speakers would overgeneralize the unmarked form (bir noun) since this is the default form used in German regardless of the context and also acceptable in all contexts in Turkish. We further hypothesized that, if they ever opt for the case marked form (bir noun+acc), they would also do so incorrectly in nonpartitive and nonspecific contexts. Turkish heritage speakers living in Germany (n= 35) could dissociate semantic contexts and made similar preferences to those of monolingual native speakers of Turkish (n= 30). Our findings suggest that native language (L1) can develop despite early onset of the L2 and be maintained on a par with monolingual norms despite the presence of competing structures in the L2. We will discuss how insights from heritage language development can contribute to discussions about the bilingual’s ability in L1; and limits and possibilities of bilingualism.
Ab Hukuk Düzeni ve Emca’da Anonim Ortaklıklarda Çoğunluğun Kötüye Kullanımının Etkilerinin Azaltılması: İzole ve Halka Kapalı Türk Anonim Ortaklıklarında Azınlığın Korunması İçin Esinlenmek Mümkün Mü?
(Istanbul Univ, Fac Law, 2024) Görmez, Onur
AB mevzuatında, çoğunluğun kötüye kullanılması hususunu düzenleyen genel bir hüküm bulunmamaktadır. Üye devletlerde ise konuya dair iki ayrı yaklaşım bulunmaktadır. Bunlardan Fransa’da kabul gören çift eşikli yaklaşım olarak adlandırılabilecek ilki hem azınlığın hem de ortaklığın çıkarının zedelenmesini aramaktadır. Almanya ve İskandinav ülkeleri gibi bazı ülkelerde kabul gören tek aşamalı yaklaşım olarak adlandırılabilecek diğer yaklaşımda yalnızca azınlığın çıkarının zedelenmesi yeterli görülmektedir. AB düzenlemeleri de dikkate alınarak akademisyenler tarafından hazırlanan bir model yasa çalışması olan EMCA’da da kendisine yer bulan ikinci yaklaşım azınlık pay sahipleri için daha iyi bir koruma sunmaktadır; özellikle izole ve halka kapalı anonim ortaklıkların azınlık pay sahipleri yönünden. Adalet Divanı’nın Audiolux kararıyla da ortaya konduğu üzere AB Hukuku’nda pay sahipleri yönünden uygulama alanı bulacak genel geçer bir eşit işlem ilkesi söz konusu değildir. EMCA’da olduğuna benzer şekilde TTK m.357’de ise eşit şartlardaki pay sahiplerinin eşit işleme tabi tutulması gerekliliğini öngören hüküm uyarınca, Türk hukukunda da ortaklıkta çoğunluğun kötüye kullanılmasının tartışma konusu olduğu hallerde, kötüye kullanmayı tespit için tek eşikli yaklaşım yeterli olmalıdır. İzole ve halka açık olmayan anonim ortaklıklarda azınlık pay sahiplerinin etkin bir şekilde korunması için uygulanabilecek yöntemler bakımından ise, sınır aşan tür değiştirme, birleşme ve bölünmeler yönünden 2017/1132 sayılı Yönerge seviyesinde de öngörülen azınlığa ortaklıktan çıkma hakkı tanıyan bir düzenlemenin getirilmesi yerinde olacaktır. Haklı nedenle feshi düzenleyen TTK m.531’in değiştirilmesi suretiyle azınlık pay sahiplerine, paylarını satarak ortaklıktan çıkmayı doğrudan mahkemeden talep edebilecekleri bir düzenleme getirilmesi de düşünülmelidir. EMCA Bölüm 11.35 ve Bölüm 11.37’deki pay sahiplerinin paylarını satarak ortaklıktan çıkması ile payların satın alınmasını talep etme veya paylarını satmaya zorlama hususlarında öngörülen hükümlerden TTK için de esinlenilebilir.

Adoption of Design Thinking in Industry 4.0 Project Management
(IGI Global, 2021) Dilan, Ebru; Aydin, Mehmet Nafiz
Management of Industry 4.0 projects needs to have a distinct discourse, be flexible, iterative and creative. These projects are tightly linked with the way people work which is directly related to both their capabilities and their ways of thinking. Challenging Industry 4.0 projects entail out-of-the-box thinking. The basic premise of this research is that the complex transformation accompanying Industry 4.0, which involves various dimensions, requires extensive and effective project management that can leverage novel approaches and techniques such as design thinking. This new approach may overcome the limitations of the dominant model of standard project management and has the potential to bridge the gap between a refreshed project management perspective and the tools/techniques in practical use. Deciding whether, and to what extent, design thinking needs to be adopted in practice in Industry 4.0 project management is a challenge. However, it is time to start exploring the challenges governing the interface between agile approaches such as design thinking and Industry 4.0 project management. © 2025 Elsevier B.V., All rights reserved.

Age Classification by WGAN Brain MR Image Augmentation
(IEEE, 2024) Yaman, Batuhan; Yilmaz, Ozge Zeynep; Darici, Muazzez Buket; Ozmen, Atilla
Medical image augmentation plays a crucial role in enhancing the performance of Artificial Intelligence (AI) applications in medical sciences. Augmenting medical images is important for solving data scarcity, increasing data diversity, enhancing robustness and reliability of model and improving training and test results that can be done in medical sciences. In this work we show that Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP) can be used for increasing the performance of data classification. To achieve that, we have augmented healthy brain MR images by using WGAN and updated the dataset. The results give that when dataset augmented by WGAN-GP is used as input for CNN-based model to solve age classification problem, accuracy of this model increases to 98,37% from 95,14%. It can be concluded that the purposed WGAN-based brain MR image augmentation method enhances the performance of image classification.

Alternative Credit Scoring and Classification Employing Machine Learning Techniques on a Big Data Platform
(Institute of Electrical and Electronics Engineers Inc., 2019) Hindistan, Yavuz Selim; Kiyakoğlu, Burhan Yasin; Rezaeinazhad, Arash Mohammadian; Korkmaz, Halil Ergun; Dağ, Hasan
With the bloom of financial technology and innovations aiming to deliver a high standard of financial services, banks and credit service companies, along with other financial institutions, use the most recent technologies available in a variety of ways from addressing the information asymmetry, matching the needs of borrowers and lenders, to facilitating transactions using payment services. In the long list of FinTechs, one of the most attractive platforms is the Peer-to-Peer (P2P) lending which aims to bring the investors and borrowers hand in hand, leaving out the traditional intermediaries like banks. The main purpose of a financial institution as an intermediary is of controlling risk and P2P lending platforms innovate and use new ways of risk assessment. In the era of Big Data, using a diverse source of information from spending behaviors of customers, social media behavior, and geographic information along with traditional methods for credit scoring prove to have new insights for the proper and more accurate credit scoring. In this study, we investigate the machine learning techniques on big data platforms, analyzing the credit scoring methods. It has been concluded that on a HDFS (Hadoop Distributed File System) environment, Logistic Regression performs better than Decision Tree and Random Forest for credit scoring and classification considering performance metrics such as accuracy, precision and recall, and the overall run time of algorithms. Logistic Regression also performs better in time in a single node HDFS configuration compared to a non-HDFS configuration.

Analysis and Optimization of the Network Throughput in IEEE 802.15.13 based Visible Light Communication Networks
(IEEE, 2021) Bulbul, Yusuf; Elamassie, Mohammed; Baykas, Tuncer; Uysal, Murat
In line with the growing interest on visible light communication (VLC), IEEE has initiated standardization efforts on this emerging technology. In this work, we consider IEEE 802.15.13 Optical Wireless Personal Area Networks (OWPAN) standard draft. The underlying MAC protocol uses contention free and contention access periods. For a standard-compliant VLC network, we analyze the network load and propose an algorithm to improve the network throughput by proper selection of period lengths. Our suggested algorithm improves the network performance by at least 5% in the case of variable network traffic up to 15 active users.

Analysis of deep learning based path loss prediction from satellite images
(IEEE, 2021) Alam, Muhammad Z.; Ates, Hasan F.; Baykas, Tuncer; Gunturk, Bahadir K.
Determining the channel model parameters of a wireless communication system, either by measurements or by running electromagnetic propagation simulations, is a time-consuming process. Any rapid deployment of network demands faster determination of at least major channel parameters. In this paper, we investigate the idea of using deep convolutional neural networks and satellite images for channel parameters (i.e., path loss exponent n and shadowing factor sigma) prediction in a cellular network with aerial base stations. Specifically, we investigate the performance dependency of the method on three different factors: height of the transmitter antenna, quantization levels of the channel parameters and architectural design of CNN. The results presented in this paper show a high prediction accuracy of the channel parameters in real-time.

An analysis of social media content shared by right-wing extremist groups in the United States, the Great Britain and Australia
(Istanbul Univ, Fac Communication, 2023) Masalha, Oday; Bas, Ozen
The extreme right movements have increasingly appeared on social media, especially on Twitter and Facebook, coinciding with the 2019 New Zealand attack, the 2019 El Paso incident, and Britain's exit from the European Union in 2020. This study examines the content and the form of extreme right-wing activities on Facebook and Twitter to promote their ideologies. A qualitative content analysis was conducted on posts shared by extreme-right groups on public Facebook and Twitter accounts in Great Britain, the United States and Australia. The sample spans from March 15, 2019 to February 5, 2020. The posts were coded according to a coding instrument developed based on the existing literature spreading extremist ideologies on social media. The coding instrument consisted of categories and subcategories such as 'the protection of western values', 'anti-LGBT activism', 'anti-feminism', 'anti-Islam', 'anti-immigrant sentiments', 'fostering the white race', and 'anti-elitist populism'. Findings suggest that the most prevalent extremist ideologies on Facebook and Twitter posts were 'anti-elitist populism' and 'the protection of western values'. Also, extremist groups heavily shared posts that combined texts and images to spread their ideologies on social media.

An Ant-Lion Optimization Based Approach to Solve Phase Balancing Problem in Distribution Networks
(IEEE, 2024) Yesilyurt, Gunnur; Ceylan, Oguzhan
Phase unbalance is a significant issue for power distribution networks. It can lead to increased energy losses and voltage instability, undermining the electrical grid's reliability and efficiency. We propose an approach to minimize voltage unbalance through reactive power management from PV installations and the optimization of charging/discharging of energy storage devices utilizing a control algorithm based on Ant-Lion Optimizer. We tested the approach on the IEEE 123-Bus Test System, incorporating PV generations by daily simulations. From the results, the combined operation of reactive power support from PVs and Storage Units with the help of the ALO algorithm offers a promising solution to the phase unbalance problem.
Application of fluorescence technique for understanding film formation from polymer latexes and composites
(Elsevier, 2021) Uğur, Ş.; Pekcan, Önder
This chapter summarizes the application of fluorescence technique to understand all aspects of film formation using both pure polymer latexes and polymer nanocomposites. Transient fluorescence, steady state fluorescence, and photon transmission techniques were used in conjunction with scanning electron microscopy/atomic force microscopy to learn this process with different latex coatings. Polystyrene latexes and poly(methyl methacrylate) latexes labeled with fluorescence probes (such as pyrene, fluorescein, and naphthalene) were used as the model polymer matrixes. We also introduced theoretical models to describe film formation stage by stage including void closure, healing, and interdiffusion and produced the activation energies related to the process. Furthermore the contributing parameters to the film formation process are identified including annealing time-temperature, solvent vapor, film thickness, particle size, and different filler materials and ratios (clay, TiO2, carbon nanotube, etc.) in both pure latex and composite systems. © 2021 Elsevier B.V.

Attentional Control Scale-Turkish Version: Psychometric Qualities, Factor Structure and Its Comparison with Behavioral Measures of Executive Attention
(ODTU-AYNA Klinik Psikoloji Destek Unitesi, 2024) Altan-Atalay, Ayse; Cinli, Dilem; Aksungur, Sebla Umay; Turkakin, Esin
Attentional control refers to the capacity to voluntarily control attentional resources in a flexible manner. Attentional control was reported to play a fundamental role in self-regulation, emotion regulation, delay of gratification, and psychological distress. The Attentional Control Scale (ACS) was developed to measure perceived attentional control based on shifting and focusing dimensions. The present studies aimed to adapt the Turkish version of ACS and asses its psychometric characteristics. Study 1 aimed to explore the psychometric qualities of the Turkish version with a group of Turkish individuals (N = 428, 306 women) between the ages of 18 and 68 and supported the two-factor model of ACS consisting of 17 items in total. The results supported that shifting, focusing, and total ACS showed adequate internal consistency, test-retest reliability, and convergent validity evidence based on its significant correlations with measures of anxiety, depression, and repetitive negative thinking, signifying its proper psychometric characteristics. In Study 2 (N = 97, 65 women), the association of ACS with behavioral attentional control measures was examined, and non-significant associations between self-report and behavioral measures of attentional control were denoted. These findings signified that rather than indicating the individual's actual attentional control capacity, ACS assessed how the individual perceives their own attention control capacities. Taken together, the results suggest that the Turkish form of ACS is a valid and reliable scale that can be used to assess perceived attentional control capacity based on shifting and focusing domains, particularly in the research setting.

Automatic Adaptation of Hypermutation Rates for Multimodal Optimisation
(Assoc Computing Machinery, 2021) Corus, Dogan; Oliveto, Pietro S.; Yazdani, Donya
Previous work has shown that in Artificial Immune Systems (AIS) the best static mutation rates to escape local optima with the ageing operator are far from the optimal ones to do so via large hypermutations and vice-versa. In this paper we propose an AIS that automatically adapts the mutation rate during the run to make good use of both operators. We perform rigorous time complexity analyses for standard multimodal benchmark functions with significant characteristics and prove that our proposed algorithm can learn to adapt the mutation rate appropriately such that both ageing and hypermutation are effective when they are most useful for escaping local optima. In particular, the algorithm provably adapts the mutation rate such that it is efficient for the problems where either operator has been proven to be effective in the literature.
