Article Citation - WoS: 1Citation - Scopus: 3The Importance of Rural, Township, and Urban Life in the Interaction Between Social and Emotional Learning and Social Behaviors(EDAM (Educational Consultancy and Research Center), 2014) Kıyar, Fatma; Totan, Tarık; Atalay, Zümra; Deniz, M. EnginWhether an individual lives in a rural or urban setting may have direct impact on a wide variety of psychological patterns adopted by students. In this study, the effects of positive and negative social behaviors on the relationship between social and emotional learning needs and skills gaps of students who reside in both rural and urban areas have been examined. The participants of this research consist of 348 female and 319 male students, forming a total of 667 middle school students living in the province of Çanakkale, Turkey as well as in its surrounding areas. The Matson Social Skills Evaluation Scale, the Social-emotional Learning Scale, the Social and Emotional Learning Skills Scale, and personal information form were used to collect data for this research. The Baron and Kenny’s approach and the Sobel test were followed during the examination of the model created in the data analysis process. The mediator test examined the effects of positive and negative social behaviors in relationship to students’ level of social and emotional learning needs and social and emotional learning skills. As a result of this test, it was found that both positive and negative social behaviors exert partial mediation effects over students living in rural and urban areas of the province of Turkey researched.Conference Object Citation - WoS: 4Citation - Scopus: 4Perceptual Coding-Based Informed Source Separation(2014) Girin, Laurent; Kırbız, Serap; Ozerov, Alexey; Liutkus, AntoineInformed Source Separation (ISS) techniques enable manipulation of the source signals that compose an audio mixture, based on a coder-decoder configuration. Provided the source signals are known at the encoder, a low-bitrate side-information is sent to the decoder and permits to achieve efficient source separation. Recent research has focused on a Coding-based ISS framework, which has an advantage to encode the desired audio objects, while exploiting their mixture in an information-theoretic framework. Here, we show how the perceptual quality of the separated sources can be improved by inserting perceptual source coding techniques in this framework, achieving a continuum of optimal bitrate-perceptual distortion trade-offs.Conference Object Citation - WoS: 9Citation - Scopus: 11A Value-Adding Approach To Reliability Under Preventive Maintenance Costs and Its Applications(2014) Dubey, Rameshwar; Kılıç, Erdem; Ali, Sadia Samar; Weber, Gerhard WilhelmNo equipment (system) can be perfectly reliable in spite of the utmost care and best efforts on the part of the designer, decision-maker and manufacturer. The two sides of maintenance are corrective and preventive maintenance. It is generally assumed that a preventive maintenance action is less costly than a repair maintenance action. We examine this proposition in detail on the basis of a failure-time model that relates conformance quality to reliability. Illustratively, we present reliability in the context of contracts with asymmetric information. The model shows how to overcome information rents through price distortions and quantity rationing. The paper ends with a conclusion and an outlook to future studies.Article Citation - WoS: 12Citation - Scopus: 17Quantification and Minimization of Sensor Effects on Modal Parameters of Lightweight Structures(JVE INTERNATIONAL LTD., 2014) Körük, HasanThis paper aims to quantify the adverse effects of contact type sensors on modal parameters of lightweight structures and to present a practical way for identification of modal parameters of structures with minimal sensor effects. The adverse effects of a contact type sensor on natural frequencies, damping levels and mode shapes are explored using the theoretical model of a typical beam-like sample carrying a sensor and a controlled experimental study based on measurement of frequency response functions using non-contact excitation and response sensors. The half-power and circle fit modal identification methods are used to extract modal parameter from measured data. The experimental and theoretical modal analysis results are evaluated, and a practical methodology based on classical acoustic and vibration frequency response functions is suggested to identify modal loss factors and natural frequencies of lightweight structures with minimal sensor effects.Article Citation - WoS: 1Citation - Scopus: 21441. Quantification of the Flow Noise in Household Refrigerators(JVE INTERNATIONAL LTD., 2014) Körük, Hasan; Arısoy, Ahmet; Bilgin, NecatiThe flow noise in household refrigerators is quantified in this study. First, the sound pressure measurements in a quiet room using typical household refrigerators are conducted and the noise characteristics of the refrigerators are presented. Then, the flow noise in household refrigerators is quantified using the results of the overall analysis and Fourier transform of the measured sound pressure data. After that, the flow noise in household refrigerators is quantified using the sound pressure measurements conducted using a specially designed test rig. The frequency characteristics of the flow noise in household refrigerators are also explored and the contribution of the flow noise is identified.Article Citation - WoS: 9Citation - Scopus: 12A New Triangular Composite Shell Element With Damping Capability(Elsevier, 2014) Körük, Hasan; Şanlıtürk, Kenan YüceThis paper presents a new triangular composite shell element with damping capability. Formulation of the composite triangular shell element is based on stacking individual homogeneous triangular shell ele- ments on top of each other. The homogeneous shell element is an assembly of a triangular membrane element with drilling degrees of freedoms and a plate element. Damping capability is provided by means of complex element stiffness matrix of individual flat layers of the composite element. These elements with damping capability allow modelling general structures with damping treatments. A few test cases are modelled using triangular finite element developed here and the results of the complex eigenvalue analyses are compared with those of the quadrilateral shell elements proposed recently. The results obtained using the presented triangular and previous quadrilateral composite elements are also com- pared with those based on modal strain energy method and experimental results. Comparisons of the experimental and the theoretical results confirm that the modal properties including modal damping lev- els of structures with damping treatments can be predicted with high accuracy using the proposed finite element.Article Citation - WoS: 3Citation - Scopus: 3Cancer Chemotherapy Treatment Patterns and Febrile Neutropenia in the Us Veterans Health Administration(2014) Wang, Li; Dale, David C; Barron, Richard; Langeberg, Wendy J; Başer, OnurBackground: The Veterans Health Administration (VHA) is the largest integrated health care system in the United States and a major cancer care provider. Objective: To use VHA database to conduct a population-based study of patterns of myelosuppressive chemotherapy use and to assess the incidence and management of febrile neutropenia (FN) among VHA patients with lung, colorectal, or prostate cancer or non-Hodgkin lymphoma (NHL). Methods: Data were extracted for the initial myelosuppressive chemotherapy course for 27,899 patients who began treatment in the period 2006 to 2011. FN-related costs were defined as claims containing FN diagnosis. Results: Most patients were men (98.0%); most were 65 years or older (55.8%). Patients received a mean 3.4 to 3.9 chemotherapy cycles/course (median cycle duration 34-43 days). The incidence of FN among patients with lung, colorectal, or prostate cancer or NHL was 10.2%, 4.6%, 5.4%, and 17.3%, respectively. Primary or secondary prophylactic antibiotics/colony-stimulating factors were received by 21% and 12% of patients, respectively. Antibiotics were more commonly given as primary or secondary prophylaxis for patients with lung, colorectal, and prostate cancer; colony-stimulating factors were more common for patients with NHL. Among patients with FN, those with lung cancer had the highest inpatient mortality (10%); patients with NHL had the highest costs ($24,571) and the longest hospital length of stay (15.4 days). Conclusions: VHA cancer care was generally consistent with National Comprehensive Cancer Network recommendations; however, compared with the general population, chemotherapy cycles were longer, combination chemotherapy was used less, and treatment to prevent FN was used less, differences that may be attributed to the unique VHA patient population. The impact of these practices warrants further investigation.Article Citation - WoS: 5Fuzzy Optimization for Portfolio Selection Based on Embedding Theorem in Fuzzy Normed Linear Spaces(De Gruyter, 2014) Solatikia, Farnaz; Kılıç, Erdem; Weber, Gerhard-WilhelmIn this paper, we propose a novel approach Embedding Theoremabout Menger probabilistic normed Spaces. The main idea behind ourapproach consists of taking advantage of interplays between Mengerprobabilistic normed spaces and normed spaces in a way to get anequivalent stochastic program. This helps avoiding pitfalls due to severe over simplification of the reality. The embedding theorem showsthat the set of all fuzzy numbers can be embedded into a Mengerprobabilistic Banach space. Inspired by this embedding theorem, wepropose a solution concept of fuzzy optimization problem which isobtained by applying the embedding function to the original fuzzyoptimization problem.Editorial Citation - WoS: 15Citation - Scopus: 14Hepatic Decompensation in Patients With Hiv/Hepatitis B Virus (hbv)/Hepatitis C Virus (hcv) Triple Infection Versus Hiv/Hcv Coinfection and the Effect of Anti-Hbv Nucleos(t)ide Therapy(2014) Wang, Li; Devine, Scott; Lo Re, Vincent, III; Olufade, Temitope; Başer, OnurThe incidence rate of hepatic decompensation was higher in patients with human immunodeficiency virus (HIV)/hepatitis B virus (HBV)/hepatitis C virus (HCV) triple infection than in those with HIV/HCV coinfection (24.1 vs 10.8 events per 1000 person-years; hazard ratio [HR], 1.89; 95% confidence interval [CI], 1.12–3.18). Compared with HIV/HCVinfected patients, the rate of decompensation was increased among HIV/HBV/HCV-infected patients receiving no anti-HBV therapy (HR, 2.48; 95% CI, 1.37–4.49) but not among those who did receive such therapy (HR, 1.09; 95% CI, .40–2.97)Article Citation - WoS: 54Citation - Scopus: 64An Assessment of the Performance of Impedance Tube Method(Institute of Noise Control Engineering, 2014) Hasan KörükThe impedance tube method is widely used for measuring sound absorption (or reflection) coefficients of acoustic materials as a function of frequency. However, the sound absorption coefficients obtained using the impedance tube method may have some variations due to the dimensions (limits) of an impedance tube, sample preparation and sample mounting. This paper assesses the performance of the two-microphone impedance tube method as a function of frequency for different tube dimensions and materials and presents suggestions for increasing the reliability and repeatability of impedance tube measurements. First, after summarizing a systematic way for measuring acoustic transfer functions, sound absorption coefficients of a variety of materials ranging from conventional absorbing acoustic materials to samples with thin films are measured using two tubes with different tube diameter and microphone spacing. Uncertainty of sound absorption coefficients for various materials is discussed, and the frequency limits of impedance tubes are assessed. Then, a method for minimizing uncertainty due to sample mounting is proposed and the main findings are discussed.Article Citation - WoS: 15Citation - Scopus: 16An Analysis of Turkey’s Water Diplomacy and Its Evolving Position Vis-À International Water Law(Taylor & Francis, 2014) Kibaroğlu, AyşegülThis article analyzes Turkey’s transboundary water policy by examining its institutional framework and basic principles. It explores the reasons why Turkey voted against the UN Watercourses Convention. Turkey’s harmonization with the water law of the European Union is also scrutinized with an aim to assess its implications for transboundary water policy making. Turkish water diplomacy faces new challenges, such as the devastating impacts of prolonged droughts as well as ongoing instability and conflicts in Syria and Iraq. Hence, it is imperative for Turkey to systematically reconcile its water policy objectives in accordance with the global norms that are adopted in this fieldArticle Citation - WoS: 30Citation - Scopus: 27Drivers of Cultural Success: the Case of Sensory Metaphors(2015) Berger, Jonah; Akpınar, EzgiWhy do some cultural items catch on and become more popular than others? Language is one of the basic foundations of culture. But what leads some phrases to become more culturally successful? There are multiple ways to convey the same thing and phrases with similar meanings often act as substitutes, competing for usage. A not so friendly person, for example, can be described as unfriendly or cold. We study how the senses shape cultural success, suggesting that compared with their semantic equivalents (e.g., unfriendly person), phrases which relate to senses in metaphoric ways (e.g., cold person) should be more culturally successful. Data from 5 million books over 200 years support this prediction: Sensory metaphors are used more frequently over time than are their semantic equivalents. Experimental evidence demonstrates that sensory metaphors are more memorable because they relate more to the senses and have more associative cues. These findings shed light on how senses shape language and the psychological foundations of culture more broadly.Book Part Strategic Fixed-Asset Management (capital Budgeting) in Small and Medium Sized Businesses(Emerald Group Publishing Ltd., 2015) Karadağ, Hande...Book Part The Role English Plays in the Construction of Professional Identities in Nest-Nnes Bilingual Marriages in İstanbul(Palgrave, 2015) Kurban, Caroline Fell…Article Citation - WoS: 15Citation - Scopus: 13Calibration of the Effective Spring Constant of Ultra-Short Cantilevers for a High-Speed Atomic Force Microscope(2015) Xu, Lin-Yan; Wu, Sen; Hu, Xiao-Dong; Song, Yun-Peng; Fu, Xing; Zhang, Jun-Ming; Dorantes-Gonzalez, Dante JorgeUltra-short cantilevers are a new type of cantilever designed for the next generation of high-speed atomic force microscope (HS-AFM). Ultra-short cantilevers have smaller dimensions and higher resonant frequency than conventional AFM cantilevers. Moreover, their geometry may also be different from the conventional beam-shape or V-shape. These changes increase the difficulty of determining the spring constant for ultra-short cantilevers, and hence limit the accuracy and precision of force measurement based on a HS-AFM. This paper presents an experimental method to calibrate the effective spring constant of ultra-short cantilevers. By using a home-made AFM head, the cantilever is bent against an electromagnetic compensation balance under servo control. Meanwhile the bending force and the cantilever deflection are synchronously measured by the balance and the optical lever in the AFM head, respectively. Then the effective spring constant is simply determined as the ratio of the force to the corresponding deflection. Four ultra-short trapezoid shape cantilevers were calibrated using this method. A quantitative uncertainty analysis showed that the combined relative standard uncertainty of the calibration result is less than 2%, which is better than the uncertainty of any previously reported techniques.Book Part An Outlook of Small and Medium Sized Enterprise (sme) Sector(Emerald Group Publishing Limited, 2015) Karadağ, Hande...Conference Object Characterizing a Highly-Accomplished Teacher’s Instructional Actions in Response To Students’ Mathematical Thinking(HAL, 2015) Taylan, Rukiye DidemThis paper is part of a larger study which investigates how a highly-accomplished teacher and two beginning teachers notice student thinking and respond to stu- dents’ mathematical thinking as they teach concepts of multiplication and division in a third-grade classroom. The focus of this paper is on describing highly-accom- plished teacher’s instructional actions in response to student thinking which are different than that of the beginning teachers. The participant teachers’ instruc- tional actions were analysed utilizing a framework de- veloped by Cengiz, Kline and Grant (2011). The results revealed that the highly-accomplished teacher chal- lenged student thinking with counter arguments and introduced alternative representations more frequently, but complimented students less frequently than the be- ginning teachers.Article Citation - WoS: 54Citation - Scopus: 64Water–energy–food Nexus in a Transboundary Context: the Euphrates–tigris River Basin as a Case Study(Taylor & Francis, 2015) Gürsoy, Sezin Iba; Kibaroğlu, AyşegülThe interlinkage between water, energy and food security and its transboundary relevance is becoming increasingly important. The paper analyses the evolution of transboundary water resources management in the Euphrates–Tigris basin with specific reference to interlinkages between water, food and energy policies at national and transboundary levels, and it explores how the policy shifts at the highest decision-making level have served to produce synergies for cooperation among the riparians or vice versa.Editorial Strategic Financial Management for Small and Medium Sized Companies Preface(Emerald Group Publishing Limited, 2015) Karadağ, Hande...Conference Object Pmh1 - Healthcare Utilization and Costs of Serotonin Syndrome With Concomitant Use of Serotonergic Agents(2015) Wang, Z.; Xie, L.; Nguyen, C; Alley, S.; Başer, OnurOBJECTIVES: Serotonin syndrome (SS) is an adverse drug reaction that may occurin patients receiving monotherapy or combinations of serotonergic agents (SAs).This study examined healthcare utilization and costs of SS in two different populations. METHODS: Adult (age ?18 years) patients prescribed SAs were identifiedusing the Veterans Health Administration (VHA) dataset (01OCT2008-30SEPT2012) andthe IMS PharMetrics Plus dataset (01JAN2010-31DEC2013). Patients with continuoushealth plan enrollment 12 months pre-index date, defined as the first SA prescription claim date, were included and observed until death, disenrollment or the end ofthe study period. Patients were assigned to cohorts based on drug exposure: singlemonoamine oxidase inhibitor (MAOI) drug, MAOI drugs in combination with otherSAs, single non-MAOI SA, and multiple non-MAOI SAs (2, 3, 4, and ?5 SAs). Outcomesof interest were annual incidences of SS event (ICD-9-CM: 333.99) and associatedhealth care utilization and costs.
