Article Violation of Public Policy as a Ground for Annulment of an Arbitral Award Within the Context of Arbitration Proceedings Conducted Pursuant to the Code of Civil Procedure(Istanbul Univ, Fac Law, 2025) Tanriver, SuhaThe subject of this study is the violation of public policy, which constitutes one of the most significant grounds for setting aside an arbitral award within the framework of arbitration proceedings conducted under the provisions of the Turkish Code of Civil Procedure. In this context, it is first demonstrated that it is difficult to provide a precise definition of public policy due to its variable nature depending on time and place. Classifications proposed in relation to this concept are addressed, and by taking into account scholarly opinions and especially judicial practice, it is determined that a violation of public policy, as a ground for setting aside, refers to contradictions with the body of institutions and rules that protect the fundamental structure and core interests of Turkish society at a given point in time. Subsequently, individual cases considered as violations of public policy-particularly in light of court decisions-are examined, and specific issues often associated with such violations are analyzed and critiqued. Finally, the study emphasizes that the determination of a violation of public policy lies within the discretion of the court, depending on the particular circumstances and features of the case. It is also noted that, even if not explicitly raised in the statement of claim for annulment, the court may consider this issue ex officio, and the related review-albeit to a limited extent-permits substantive scrutiny of the arbitral award.Conference Object Covariance Features for Trajectory Analysis(Institute of Electrical and Electronics Engineers Inc., 2016) Karadeniz, T.; Maras, H.H.In this work, we aimed to demonstrate that covariance estimation methods can be used for trajectory classification. We have shown that, features obtained via shrunk covariance estimation are suitable for describing trajectories. We have arrived to the conclusion that, when compared to Dynamic Time Warping, the explained technique is faster and may yield more accurate results. © 2017 Elsevier B.V., All rights reserved.Article Americanization of Political Campaigns: a Comparison of the Cases of Forza Italia and the Young Party(Turkiye Orta Dogu Amme Idaresi Enstitusu, 2010) Turk, Hasan Bahadir; Türk, Hasan Bahadır; Siyaset Bilimi ve Uluslararası İlişkilerSimilar to political institutions and structures, political campaigns have also undergone dramatic transformations. The Americanization of political campaigns, which are characterized by certain peculiarities, such as the personalization of politics, weakening of party organizations, wide use of media channels in the political marketing process, need for specialization, primacy of opinions over ideologies and conceptualization of citizens as policy consumers, is a by-product of these dramatic transformations. This paper aims to compare Forza Italia and the Young Party through the Americanization of political campaigns with special emphasis on the connection between the transformation of political campaigns and the crisis of representative democracy.Article Citation - WoS: 7Citation - Scopus: 8Psychometric Properties of the Turkish Version of Cohen- Mansfield Agitation Inventory in Patients With Dementia(Gunes Kitabevi Ltd Sti, 2012) Baştuğ, Gülbahar; Ozel-Kizil, E. Tugba; Bastug, Gulbahar; Erdogan, Seyda; Sakarya, Direnc; Durmaz, Nazli; PsikolojiIntroduction: Cohen-Mansfield Agitation Inventory (CMAI) is frequently used in patients with dementia for the assessment of agitation severity. This instrument is especially used in research investigating the severity of behavioral symptoms and their treatment responses. In this study, psychometric properties of the Turkish version of CMAI were investigated in patients with dementia (n=52). Materials and Method: CMAI-Turkish version was applied by face-to-face interview to the caregivers of dementia patients who were admitted to a geriatric psychiatry outpatient clinic. For validity, the correlations between CMAI total scores and Neuropsychiatry Inventory (NPI) total and subscale scores were evaluated. For internal consistency, Cronbach alpha value of the items was calculated. Results: CMAI scores were significantly correlated with NPI scores and Cronbach alpha value of the scale was high (0.89). Conclusion: Turkish version of CMAI is a valid and reliable tool for the assessment of the frequency and severity of agitation behavior. Further studies might evaluate inter-rater reliability of the scale in inpatients with dementia.Article Citation - WoS: 25Citation - Scopus: 31Supporting Foreign Language Vocabulary Learning Through Multimedia Messages Via Mobile Phones(Hacettepe Univ, 2010) Saran, Murat; Saran, Murat; Seferoglu, Goelge; Bilgisayar MühendisliğiThis study explored the effectiveness of mobile learning in foreign language education. With this purpose, instructional materials to be delivered through mobile phones operated in second generation GSM technology in order to improve English language learners' vocabulary acquisition were developed. The multimedia messages in this study allowed students to see the definitions of words, example sentences, related visual representations, and pronunciations. After students finished reading multimedia messages, interactive short message service (SMS) quizzes for testing their learning were sent. In addition, the study examined students' tendencies in using MMS in their second language vocabulary study and explored the opinions of the students toward the use of mobile phones for instructional purposes. The findings of this study suggest some important points to consider while creating MMS content and a SMS quiz system for educational purposes.Editorial The Bright and Dark Sides of Work Life" Tpd Work and Organizational Psychology Special Issue(Turkish Psychologists Assoc, 2019) Sumer, H. Canan; Goncu-Kose, Asli; Toker, Yonca; Ok, A. Basak; Gokalp, Aysu; Mete, Ipek; Demircioglu, Zeynep IsilArticle Experimental Study and Theoretical Investigation of High Temperature Proton Exchange Membrane Fuel Cell Micro-Cogeneration Application(Turkish Soc thermal Sciences Technology, 2018) Yapıcı, Ekin; Devrim, Yilser; Ozgirgin Yapici, Ekin; Makine MühendisliğiIn this study, a house hold micro-cogeneration system is designed using high temperature proton exchange membrane (HTPEM) fuel cell. HTPEM type fuel cells gain the highest interest lately, due to their advantages in terms of increasing efficiency and power quality, reducing harmful emissions and flexibility of operation with respect to the other fuels. The micro-cogeneration system involves producing both electrical energy and hot water and/or vapor together in an economical way, utilizing single fuel (HTPEM fuel cells) for household applications. During the operation of the fuel cell, for high efficiency and stable power production, the access heat of the stack should be removed constantly and the temperature of the stack should be held stable. Heat recovered from the designed innovative cooling system is used for acquiring energy for heating water. This way, thermal efficiency is almost doubled compared to simple cycle. In the scope of this study, 225 W HTPEM fuel cell stack is designed and tested at 160 degrees C operation temperature with hydrogen gas and air. During operation, for homogenous distribution of temperature among the cells, for a short start up period leading to a fast required steady state temperature and for constantly removing the access heat produced in the cell, the cell stack is cooled by using a cooling fluid (Heat Transfer Oil 32- Petrol Ofisi). Selection of insulation material type and thickness for the cell stack is done using natural convection and radiation loss calculations. For the most efficient operating conditions, micro-cogeneration system water inlet and exit temperatures, water and cooling fluid flow rates, convenient pipe diameter and pump power calculations are done to finalize the design. With the cogeneration system designed during the studies, by recovering the access heat of the insulated HTPEM cell stack, district water with initial temperature of 15-20 degrees C is heated around 50 degrees C. Data gathered during studies indicate that fuel cell micro-cogeneration application is highly viable.Article Citation - WoS: 6Investigation of the Psychometric Properties of the Turkish Form of Subjective Memory Complaints Questionnaire(Gunes Kitabevi Ltd Sti, 2013) Ozel Kizil, Erguvan Tugba; Baştuğ, Gülbahar; Duman, Berker; Altintas, Ozge; Kirici, Sevinc; Bastug, Gulbahar; Baran, Zeynel; Altunoz, Umut; PsikolojiIntroduction: Amnestic type of mild cognitive impairment (MCI) is characterized by the presence of subjective memory complaints and impairment of memory tests. This study aims to investigate the validity and reliability of the Turkish Version of the Subjective Memory Complaints Questionnaire (SMCQ). Materials and Method: The study sample consisted of 45 MCI patients and 44 healthy elderly controls. The SMCQ is a 14-item, "yes-no" questionnaire which evaluates the severity of subjective memory complaints. The discriminant validity of SMCQ was evaluated by comparing the scores of the two groups. For concurrent validity, the correlations between SMCQ and two widely-used cognitive screening tests (MMSE and ADAS-Cog) were calculated. ROC analysis was performed to test the diagnostic validity. For reliability analysis, internal consistency was calculated. Results: SMCQ scores of the patients were higher than the controls. SMCQ scores of the subjects were positively correlated with ADAS-Cog and negatively correlated with MMSE scores. Cronbach's value was 0.83. ROC analysis yielded a sensitivity of 80% and a specificity of 66% (cut-off=4.5). Area under the curve was 0.843. Conclusion: SMCQ is a valid and reliable instrument that can be used for the assessment of SMC in elderly patients. However, community based studies should be carried out for suggesting SMCQ as a screening tool.Article The Problem of Checking The Political Power in The Tradition of Siyasat-Nama: The Case of Nushatu's-selatin(Turkiye Orta Dogu Amme Idaresi Enstitusu, 2017) Turk, Hasan Bahadir; Türk, Hasan Bahadır; Siyaset Bilimi ve Uluslararası İlişkilerThe problem of how to be able to check the political power lies at the very heart of the historical debates over politics. This problem is part and parcel of another vital political problem that can be best described as the necessity of setting limits to the power of rulers. Accordingly, one might argue that checking the political power and setting limits to it are not basically and simply the same thing. This paper, moving from this assumption, attempts to shed some light upon the problem of checking the political power through the lenses of an Ottoman bureaucrat of the sixteenth century, namely, Mustafa Ali of Gallipoli. In so doing, the paper focuses on a text written by Mustafa Ali in 1581. The major argument of this paper is that Mustafa Ali's text, Nushatu'sSelatin (Advices to Sultans), which is an example of Siyasat-nama genre of books, deals with the problem of checking the political power with a particular emphasis upon three certain principles: Justice, fear of God and merit.Article Citation - WoS: 5Citation - Scopus: 5Ann and Anfis Performance Prediction Models for Francis Type Turbines(Turkish Soc thermal Sciences Technology, 2020) Aylı, Ülkü Ece; Ayli, Ece; Ulucak, Oguzhan; Makine MühendisliğiTurbines can be operated under partial loading conditions due to the seasonal precipitation fluctuations and due to the needed electrical demand over time. According to this partial working need, designers generate hill chart diagrams to observe the system behavior under different flow rates and head values. In order to generate a hill chart, several numerical or experimental studies have been performed at different guide vane openings and head values which are very time consuming and expensive. In this study, the efficiency prediction of Francis turbines has been performed with ANN and ANFIS methods under different operating conditions and compared with simulation results. The obtained results indicate that it is possible to obtain a hill chart using ANFIS method instead of a costly experimental or numerical tests. ANN and ANFIS parameters which effect the output, have been optimized with trying 100 different cases. 75% of the numerical data set is used for training and 25 % is used for validation as testing data. To asses and compare the performance of multiple ANN and ANFIS models several statistical indicators have been used. Insight to the performance evaluation, it is seen that ANFIS can predict the efficiency distribution with higher accuracy than the ANN model. The developed ANFIS model predicts the efficiency with 1.41% mean average percentage error and 0.999 R-2 value. To the best of the author's knowledge, this is the first study in the literature that ANN and ANFIS are used in order to predict the efficiency distribution of the turbines at different loading conditions.
