Investigating the Relationship Between Volitional Strategies and Academic Achievement in a Flipped Learning Environment
(Fac Teacher Education, 2019) Seggie, Fatma Nevra; Kiziltepe, Zeynep; Birgili, Bengi
This study was conducted to determine whether there is a relationship between academic volitional strategies and academic achievement in a flipped learning environment. Academic achievement entails an environment where students exert self-discipline on classroom tasks. By using volitional strategies, learners can enhance engagement on academic tasks and complete assignments more efficiently. Undergraduate students enrolled in a teacher education programme at a higher education institution in Turkey participated in the research. Academic Volitional Strategies Inventory (AVSI), with alpha = .87 internal consistency, was applied to a group of students. The obtained data were explored through Pearson correlation. The results showed a statistically significant positive relationship between AVSI scores and academic achievements (r =.39, p=<.05). Hence, volitional skills and academic achievements act in concert in a teacher education programme.

Attachment Insecurity and Restrictive Engulfment in College Student Relationships: the Mediating Role of Relationship Satisfaction
(Emerald Publishing Limited, 2018) Hatipoğlu Sümer, Zeynep; Murray, Christine; Toplu Demirtaş, Ezgi
Purpose Studies on restrictive engulfment (RE) – a subtype of psychological aggression in intimate relationships – have focused either on insecure attachment or relationship satisfaction, not both. Therefore, the purpose of this paper is to investigate relationship satisfaction as a potential mediator of the associations between anxious and avoidant attachment and RE perpetration among college students. Design/methodology/approach A sample of 322 college students (178 women, 137 men, and seven other gender-identified) completed the experiences in close relationship inventory, relationship assessment scale, and RE subscale of the multidimensional measure of emotional abuse. Findings Among the sample, 89.3 and 90.5 percent of the college women and men, respectively, reported to have used isolating, restricting, monitoring, and controlling behaviors. The results of structural equation modeling revealed that all direct paths except for that from avoidant attachment to RE were significant. Moreover, significant indirect paths were identified from anxious and avoidant attachment to RE via relationship satisfaction. Research limitations/implications The results of this study should be interpreted with consideration of the study’s limitations. First, the data were drawn from a convenience sample of Turkish college students. Second, the design of the study is correlational; therefore, we cannot assume causality. Finally, this study utilized self-report and retrospective data. Practical implications Though the findings are preliminary, they may inform college counselors and other mental health practitioners about the nature of RE within college students’ dating relationships. College students who are unhappy with their dating relationships but still in those relationships (i.e. they choose not to leave) should be assessed for whether they are the perpetrators and/or recipients of psychological aggression, especially in light of the high rates of this form of aggression in the current and previous studies. Furthermore, assessing psychological dating aggression perpetrators for insecure attachment styles may help mental health professionals who work with college students, envisage the sessions toward areas in the need of improvement, such as their views of themselves and others. Self-esteem, feelings of insecurity and inadequacy in relationships, and dependency can be worked with these clients. Social implications The results of this study also have implications for the prevention of psychological aggression before it occurs. The need for prevention programs is evident in the high rates of psychologically controlling behaviors among college students. It may be useful to implement campus wide programs to raise awareness regarding psychological aggression, such as through events, seminars, posters, flyers, and talks with student groups. Originality/value Despite the limitations of this study, its findings offer insight into the factors that influence the perpetration of psychological aggression within dating relationships among college students. Adult attachment theory offers a useful lens for understanding the possible driving forces behind college students’ controlling behaviors toward their dating partners. In particular, college students who demonstrate an insecure attachment style – and especially an anxious attachment style – combined with low levels of relationship satisfaction appear to be at a high risk for perpetrating RE behaviors.

Identification of Candidate Biomarkers and Pathways in Breast Cancer by Differential Network Analysis
(Inderscience Publishers, 2020) Mendi, Onur; Karahoca, Adem
Breast cancer is one of the most malignant cancers in women worldwide. The aim of the present study was to explore the underlying biological mechanisms of breast cancer. For this purpose, we propose a novel framework to reveal mechanisms that drive disease progression in breast cancer by combining prior knowledge in the literature with differential networking methodology. Our integration framework has resulted in the most important genes and interactions by allowing ranking the breast cancer-specific gene network. YY1, SMARCA5, FOXM1, STAT4 and PTTG1 were found to be the most important genes in breast cancer. Functional and pathway enrichment analyses identified numerous pathways that may play a critical role in disease progression. Considering the success of the comparison of the results with the literature, the systemic lupus erythematosus pathway may be a potential target of breast cancer.
The Moderation Role of Supervisor Support in the Interaction of Illegitimate Task, Emotional Exhaustion, and Self-Undermining: a Job-Demand Resources Approach
(Sage Publications Ltd, 2025) Konuk, Hızır; Küçük, Burcu Aydın
The study aims to reveal both the direct and indirect association between Illegitimate Tasks and Self-Undermining behavior through Emotional Exhaustion, with a focus on the moderating role of Supervisor support. It also seeks to highlight the conditions under which Supervisor support provides positive organizational outcomes. A survey was applied to 978 white-collar participants working in SMEs in Turkey. The Job-Demand Resources framework served as the theoretical basis for the research. Results indicated that Illegitimate Tasks are associated with self-undermining, with emotional exhaustion partially mediating this relationship. Supervisor support was found to have a negative relationship with emotional exhaustion and self-undermining; however, its moderating role was positive rather than negative. Supervisor support increased the effect of illegitimate tasks on emotional exhaustion and self-undermining, contradicting the expected buffering effect. The study contributes to the literature by offering evidence on when supervisor support becomes dysfunctional for organizations.
The Blue Peace: Achieving Peace and Security Through Water Cooperation
(SETA, 2015) Ahmmad, Yadgar; Kibaroğlu, Ayşegül; Vishwanath, Ambika
Water is about people and human security. Unfortunately water has become a source of conflicts around the world, especially in the Middle East. There is a critical need for active water cooper- ation between nations in the region. This article discusses possible ways to achieve such cooperation, using tools developed under the Blue Peace concept. The article highlights a positive example of con- crete steps taken by Turkey and Iraq in the area of track-two hydro diplomacy, which could potentially expand to other countries in the region. Experiences from around the world demonstrate that sustainable active water cooperation is possible and there are many examples that could be adapted by countries in the Middle East.

Majority Grievance in Germany: the Role of Entitlement Beliefs and Ingroup Threat
(Educational Publishing Foundation-american Psychological Assoc, 2023) Stucke, Frederike; Okuyan, Mukadder; Loreth, Lukas
Group-based grievance has mainly been studied from the perspective of disadvantaged and minority groups. Following the refugee crisis and corresponding sociopolitical changes, there has also been an increase in perceived grievance among majority groups in many European countries. The present studies examined the role of perceived threat in the relationship between autochthony-based entitlement and group grievances among members of the German majority. Across three correlational studies, we tested whether threat moderates versus mediates this relationship. In Study 1, using a nationally representative sample, we found support for threat serving as a mediator of the relationship between autochthony-based entitlement and majority grievance. We replicated this finding in Studies 2 (N = 380) and 3 (N = 614) using convenience samples. We discuss the diverse roles played by perceived threat in predicting defensive reactions by majority groups and the importance of studying perceived entitlement in majority groups' grievance claims.

Developmental Health Services Leadership: Integrating Hierarchical and Shared Leadership for Health Services Organizational Learning
(2015) Pearce, Craig L.
The purpose of this article is to articulate a model of, as well as a call to action for, health services leadership, with a particular emphasis on the role of health services leadership in organizational learning. More specifically, I articulate a model that poses two antecedents of health services hierarchical leadership-leader responsibility disposition and environmental cues-as important predictors of empowering leadership. In turn, I assert that empowering leadership from above will engender an inclination toward shared leadership among followers. Subsequently, I venture that both empowering hierarchical leadership and shared leadership are precursors of health services organizational learning. I specify several research directions for future scholarship. More importantly, I identify multiple measures that policy makers and practitioners can take to enhance health services leadership and organizational learning.

Nonlinear Benefit-Cost Optimization-Based Selection of Insulation Material and Window Type: a Case Study in Turkey
(2017) Ağralı, Semra; Uctuğ, Fehmi Görkem
In this study, we maximize the energy savings of a hypothetical household by choosing an optimal insulation material with its optimal thickness and also the optimal window type. We develop a nonlinear mixed integer optimization model that maximizes the net present value of the benefits obtained by insulation over the lifespan of the house. Savings are calculated based on the gains from the electricity usage for air conditioning during cooling-required days and the fuel usage for heaters in heating-required days. The heat transfer calculations consider conductive, convective, and radiative components simultaneously. The optimization model takes the climate conditions of the region where the house is located, the consumer's desired indoor temperature, and the properties of the insulation options; then, it returns a combination of selected insulation materials with its optimum thickness and window type as output. We applied the optimization model developed to hypothetical houses in four different climatic regions of Turkey for different lifespans. For all reasonable lifespans, the model choses stonewool as the ideal insulation material. For high interest rates, single windows or double-glazed windows are preferable, but as the interest rate decreases and the net present value of the energy-savings increases, the model prefers triple-glazed windows as the ideal material. Erzurum, a city in climatic region 4, characterized by very cold winters and cool summers, was found to require the highest optimum insulation thickness, and the economic return resulting from the above-mentioned energy-saving actions was also found to be the highest in the case of Erzurum. In all the regions, the energy-saving investments were found to be feasible via applying the feasibility assessment techniques of net present value and payback period. The model developed in this study is applicable to any household as long as the required input data are available. Published by AIP Publishing.

Can Managers Become Entrepreneurs? a Moderated Mediation Model of Entrepreneurial Intention
(John Wiley and Sons, 2020) Şahin, Faruk; Karadağ, Hande
This study investigates the role of entrepreneurial knowledge on the formation of entrepreneurial intentions in a sample of 190 middle‐level managers by extending the theory of planned behaviour (TPB). Findings indicate that entrepreneurial knowledge has a significant and positive effect on entrepreneurial intention (EI), whereas personal attitude (PA) and personal behavioural control (PBC) mediate the relationship between entrepreneurial knowledge and intention. Findings also indicate that the third construct of TPB, namely social norm, moderates the mediating role of the indirect intention effect of entrepreneurial knowledge through PA and PBC differently. Together, the findings suggest several directions for managers and organizations, as well as policy‐makers, who are responsible for creating more productive and innovative entrepreneurial ventures.

Evaluation of a Strategic Management Program: Context, Input, Process, Product Model as a Prototype for Business Academies
(TECHNOLOGY EDUCATION MANAGEMENT INFORMATICS, 2021) Kırkıç, Kamil Arif; Birgili, Bengi
The present study examines the evaluation models of strategic management (SM) programs in business academies and evaluates a sample program based on Stufflebeam's context, input, process, product (CIPP) program evaluation model. When evaluation studies used in Turkey were scrutinized, Stake's countenance model and Provus's discrepancy model were also discovered; however, the CIPP Model has generally been used. Further, this study explores (1) the history of SM education and (2) SM education within the perspectives of business academies, (3) a sample of SM education developed by a private education consulting service and (4) a theoretical background and a practical method to evaluate the program of business academies.
The Future of Türkiye-NATO Relations in Light of the Strained Transatlantic Dialogue
(Seta Foundation, 2025) Kibaroğlu, Mustafa
This commentary aims to assess the impact of the changing approach of the U.S. under Trump's second administration on transatlantic relations, the future of NATO, its engagement in the war in Ukraine, and the prospects for further expansion toward the east. The paper also aims to shed light on how these developments may affect the future of Türkiye-NATO relations. While Türkiye remains a critical NATO member due to its strategic geography and military capabilities, domestic skepticism towards the Alliance has grown in response to unresolved disputes and perceived double standards. The commentary ultimately underscores that Türkiye’s future in NATO will depend on the Alliance’s ability to reconcile internal divisions, recalibrate its strategic vision, and balance Türkiye’s security concerns with broader transatlantic priorities. © 2025, SETA Foundation.

Characterization of Viscoelastic Materials Using Free-Layered and Sandwiched Samples: Assessment and Recommendations
(Polish Physical Society, 2015) Özer, Mehmet Sait; Körük, Hasan; Şanlıtürk, Kenan Yüce
Viscoelastic materials are widely used in many applications in practice. However, determination of the elastic and damping properties of these materials is quite difficult in the sense that the identified results may contain high degree of uncertainty. The characterization of viscoelastic materials using the Oberst beam method, based on non-contact excitation and response measurements, is revisited in this paper. The effects of signal processing parameters such as frequency resolution in Frequency Response Function (FRF) measurements, as well as the effects of various single-degree-of-freedom modal analysis methods, including circle-fit, half-power and line-fit are investigated first. Then, the modal loss factors, Young's modulus and shear modulus of some sample viscoelastic materials are identified using both the free-layered and sandwiched samples. The results obtained from different tests are compared, discussed and some recommendations are made so as to identify the damping and elastic properties of typical viscoelastic materials with better accuracy. Analyses of a large number of FRF measurements show that the selection of the appropriate signal processing parameters and the use of appropriate modal analysis method can be very significant during the identification of viscoelastic materials. By following the approach presented in this paper, the damping and elastic properties of viscoelastic materials can be identified with better accuracy using either free-layered or sandwiched samples. The material properties obtained by this approach can be used for developing valid structural models and/or for damping optimization purposes.

Extension of Capital Budgeting Techniques Using Interval-Valued Fermatean Fuzzy Sets
(IOS Press, 2022) Sergi, Duygu; Sarı, İrem Uçal; Senapati, Tapan
Capital budgeting requires dealing with high uncertainty from the unknown characteristics of cash flow, interest rate, and study period forecasts for future periods. Many fuzzy extensions of capital budgeting techniques have been proposed and used in a wide range of applications to deal with uncertainty. In this paper, a new fuzzy extension of the most used capital budgeting techniques is proposed. In this content, first interval-valued Fermatean fuzzy sets (IVFFS s) are defined, and the algebraic and aggregation operations are determined for interval-valued Fermatean fuzzy (IVFF) numbers. The formulations of IVFF net present value, IVFF equivalent uniform annual value, and IVFF benefit-cost ratio (B/C) methods are generated. To validate the proposed methods, proposed formulations are illustrated with a hypothetical example, and the results are compared with classical fuzzy capital budgeting techniques.

Quantification and Minimization of Sensor Effects on Modal Parameters of Lightweight Structures
(JVE INTERNATIONAL LTD., 2014) Körük, Hasan
This 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.
Calling for a Reset in Turkish-American Relations in the Post-COVID International Order
(SETA Foundation, 2020) Kibaroğlu, Mustafa
Analysts emphasize that nothing will be the same after the pandemic and refer to the ‘new normal’ that is likely to prevail everywhere in the world. It would be a legitimate question to ask if this would provide a conducive environment for Turkey and the United States to reset their relations that have much deteriorated lately. This article will, first, highlight the contours of the ‘new normal’ narrative by referring to the views expressed by politicians, academics, analysts, journalists and intellectuals from around the world. Second, the article will assess the implications of the parameters of the ‘new normal’ for key actors in world politics, such as the United States, China, the European Union and Russia, as well as Turkey’s Middle Eastern neighbors, with respect to the issues that will be at stake in the international security environment. Finally, the article will make a call for a reset in Turkish-American relations in order for the two long-standing allies to adapt themselves better to post-COVID international politics. © 2020, SETA Foundation.

Understanding the Psychological and Financial Correlates for Consumer Credit Use;
(Sosyoekonomi Society, 2024) Ertuğrul, Seyit; Sayar, Alperen; Şahin, Türkay; Çakar,Tuna
This study investigated the behavioural and cognitive predictors of consumer credit usage to develop a behavioural credit risk assessment procedure for a factoring company. Participants completed surveys measuring personality traits, self-esteem, material and monetary values, compulsive and impulsive buying tendencies, self-control, and impulsiveness. Financial surveys also assessed financial literacy and knowledge of financial concepts. The results indicated that extraversion, conscientiousness, emotional stability, and experiential self-control were significant predictors of consumer credit usage. These findings suggest that a finance company can use these personality traits and financial characteristics to develop a more accurate and effective credit risk assessment procedure, such as psychometric tests. © 2024, Sosyoekonomi Society.

(University of Latvia, 2022) Kulavuz, Bahadır; Ertuğrul, Berkay; Bakırman, Tolga; Çakar, Tuna; Doğan, Metehan; Bayram, Bülent; Bayram, Buket
Skin cancer is one of the most dangerous cancer types in the world. Like any other cancer type, early detection is the key factor for the patient's recovery. Integration of artificial intelligence with medical image processing can aid to decrease misdiagnosis. The purpose of the article is to show that deep learning-based image classification can aid doctors in the healthcare field for better diagnosis of skin lesions. VGG16 and ResNet50 architectures were chosen to examine the effect of CNN networks on the classification of skin cancer types. For the implementation of these networks, the ISIC 2019 Challenge has been chosen due to the richness of data. As a result of the experiments, confusion matrices were obtained and it was observed that ResNet50 architecture achieved 91.23% accuracy and VGG16 architecture 83.89% accuracy. The study shows that deep learning methods can be sufficiently exploited for skin lesion image classification. © 2022 Baltic Journal of Modern Computing. All rights reserved.

Assessment of the Disaster Recovery Progress Through Mathematical Modelling
(TMMOB İnşaat Mühendisleri Odası, 2020) Dikmen, Seyyit Ümit; Sönmez, Murat; Akbıyıklı, Rıfat
Natural disasters, especially major earthquakes, cause widespread devastation in the built environment. Hence, the major component of the recovery in its aftermath constitutes a chain of projects starting at different times, having different costs and durations. In this study, the post disaster recovery curve modelled through a mathematical approach taking into account these properties of the projects. The approach followed is based on the project S-curve concept that provides the opportunity to simulate the progress by outlining the project spending. Well-known mathematical functions are adapted to model the project spending and the handover processes. Monte Carlo simulation is performed to evaluate the general behavior of the recovery curve using the model developed. Weibull distribution is used to generate the model’s parameters. Results of the Monte Carlo simulation demonstrate that the recovery process exhibits an S-shape, the duration of initial portion and the slope of the bulk portion being significantly governed by the level of preparedness of the community.

Exploring the Drivers of Green Purchase Behaviour: the Moderating Roles of Perceived Expensiveness and Green Scepticism
(inderscience Enterprises Ltd, 2024) Aydın, Kenan; Altan, Meral Uzunöz; Köse, Şirin Gizem; Çizer, Ece Özer
This research aims to investigate factors affecting green consumption behaviour by utilising theory of planned behaviour and extends the theory by integrating environmental attitude, perceived expensiveness, and green scepticism variables. The results show that environmental attitude, attitude towards purchasing green products, subjective norms, and perceived behaviour control variables determine green product consumption. The study also presents the partial mediator role of attitude towards buying green products in the relationship between environmental attitude and green product purchase behaviour. Furthermore, perceived expensiveness and green scepticism have negative moderating roles in the relationship between attitudes toward purchasing green products and green purchase behaviour.
