Book Part Mobile Mars Habitation(Springer International Publishing, 2023) Müge Halıcı, Süheyla; Özdemir, KürşadThis chapter focuses on the concept of mobile habitation on Mars. A description of Mars’ surface features is followed by a review of early concepts of crewed mobility for the Moon and Mars. Wheeled concepts for crew mobility continue to be based on the success of the Lunar Roving Vehicle, and predominantly take the form of a pressurized rover on wheels. With the help of architectural diagrams, the chapter introduces a range of habitable and mobile Mars structures, and the technologies used, taking into account mission requirements. © Springer Nature Switzerland AG 2023, corrected publication 2023.Article Citation - WoS: 6Citation - Scopus: 8Social Support and Help-Seeking Worldwide(Springer, 2024) Szkody, Erica; Spence, Anjolee; Ozdogru, Asil; Tushir, Bhawna; Chang, Fennie; Akkas, Handan; Cascalheira, Cory J.; Karakulak, ArzuSocial support has long been associated with positive physical, behavioral, and mental health outcomes. However, contextual factors such as subjective social status and an individual's cultural values, heavily influence social support behaviors (e.g., perceive available social support, accept support, seek support, provide support). We sought to determine the current state of social support behaviors and the association between these behaviors, cultural values, and subjective social support across regions of the world. Data from 6,366 participants were collected by collaborators from over 50 worldwide sites (67.4% or n = 4292, assigned female at birth; average age of 30.76). Our results show that individuals cultural values and subjective social status varied across world regions and were differentially associated with social support behaviors. For example, individuals with higher subjective social status were more likely to indicate more perceived and received social support and help-seeking behaviors; they also indicated more provision of social support to others than individuals with lower subjective social status. Further, horizontal, and vertical collectivism were related to higher help-seeking behavior, perceived support, received support, and provision of support, whereas horizontal individualism was associated with less perceived support and less help-seeking and vertical individualism was associated with less perceived and received support, but more help-seeking behavior. However, these effects were not consistently moderated by region. These findings highlight and advance the understanding of how cross-cultural complexities and contextual distinctions influence an individual's perception, processing, and practice of social support embedded in the changing social landscape.Article Citation - WoS: 1Citation - Scopus: 2The Mediating Role of Instructional Design and Video Length Between Grade Level and Pupil-Content Interaction in Instructional Mathematics Videos on Youtube(Springer, 2024) Demir, Ömer; Birgili, BengiThe use of instructional videos is rampant in education; however, their interaction is limited by weak instructional design. Gagne has never insisted on using his renowned 9 Events of Instruction slavishly in situations as a viable paradigm for utilization in video design. Connecting grade level, video length, and interaction, this study seeks to determine the relevance of Gagne's prescribed 9 event sequence in instructional mathematics videos. We scrutinized 50 instructional mathematics videos on YouTube geared towards middle school pupils ranging between 5th and 8th grades. We used quantitative media content analysis for video analysis. In data analysis, partial least squares were used. Bayesian estimation was also resorted to for cross checking. The data revealed that one-third of Gagne's instructional design steps were not always present: activating prior knowledge, eliciting performance, and finally providing feedback. A mediation analysis between grade level and video length revealed that 6 events fully mediated the association between the two. We also elicited the impact of these variables on affective and behavioral interactions in videos. This study assists in creating an idiosyncratic instructional design model, called Birgili's 8 steps for instructional video design, and in infusing this with a melange of four theories. In contrast with the status quo attesting that the literature abounds with scholarly works touting the shorter is the better mantra, the results substantiated that longer may be better in leveraging video interactions provided that the length is judiciously used to conform to instructional design principles.Article Citation - WoS: 2Citation - Scopus: 2Reconnaissance and Discussion on Ground Motion Induced by the 2023 Türkiye-Syria Earthquake(Taylor and Francis Ltd., 2025) Towhata, I.; Çağlayan, P.Ö.; Tönük, G.; Erginağ, U.C.; Sendir Torisu, S.This paper discusses the output from the damage reconnaissance conducted after the 2023 Türkiye-Syria earthquake. First, a large landslide occurred in a limestone gentle slope without much ground water. Second, the ground subsidence in the coastal area does not comply the the local soil conditions and other observed post-seismic situations. Third, the acceleration records exhibit stronger motion with longer period and shorter duration towards the western end of the causative fault and suggest supershear rupture. To understand these features of the ground motion, this paper proposes a hypothetical model that can reproduce these observations to a good extent. © 2025 Taylor & Francis Group, LLC.Article Citation - WoS: 2Citation - Scopus: 2Warning Notes in a Learner’s Dictionary: a Study of the Effectiveness of Different Formats(International Journal of Lexicography, 2022) Çakar, Tuna; Nesi, Hilary; Nural, ŞükrüThis study used an online correction task to explore the extent to which different types of warning notes in Longman Dictionary of Contemporary English Online were heeded when users tried to correct errors in the use of L2 target words. The task was completed by 332 participants, yielding 1,819 answers produced after clicking on links to relevant entries. Warning notes were categorised in terms of their formatting features, but there were found to be inconsistencies in the way the dictionary associated different categories with different kinds of learner error. Participants judged warning notes with more visual enhancements to be more useful, but in the correction task the position of the warning notes also seemed to affect the degree to which the warnings were successfully applied. Different types of warning notes in learners’ dictionaries have not been examined previously in any depth, and the results suggest that some adjustments to formatting and placement might make them more effective.Conference Object Citation - WoS: 2Citation - Scopus: 5Compositional Neural Network Language Models for Agglutinative Languages(2016) Saraçlar, Murat; Arısoy, EbruContinuous space language models (CSLMs) have been proven to be successful in speech recognition. With proper training of the word embeddings, words that are semantically or syntactically related are expected to be mapped to nearby locations in the continuous space. In agglutinative languages, words are made up of concatenation of stems and suffixes and, as a result, compositional modeling is important. However, when trained on word tokens, CSLMs do not explicitly consider this structure. In this paper, we explore compositional modeling of stems and suffixes in a long short-term memory neural network language model. Our proposed models jointly learn distributed representations for stems and endings (concatenation of suffixes) and predict the probability for stem and ending sequences. Experiments on the Turkish Broadcast news transcription task show that further gains on top of a state-of-theart stem-ending-based n-gram language model can be obtained with the proposed models.Review Citation - WoS: 29Citation - Scopus: 38State-Of Review of Transboundary Water Governance in the Euphrates–tigris River Basin(Taylor & Francis, 2019) Kibaroğlu, AyşegülThis article reviews the state of the art of transboundary water governance in the Euphrates–Tigris river basin, which is characterized by both political confrontation and cooperative institutional development. First, research on the physical characteristics of the basin is presented, with references to the literature on large-scale water development projects that underpin transboundary water interactions. Then, contending approaches to transboundary water governance are discussed, with specific references to the evolution of institutions. Finally, bearing in mind that transboundary water governance in the basin occurs in volatile political circumstances, current issues such as control of the water infrastructure by non-state violent actors and protection of water during armed conflict are scrutinized.Article Citation - WoS: 7Citation - Scopus: 7But the Poor Needed It More: Children's Judgments on Procedural Justice To Allocate Resources Between Two Candidates Equal in Merit, Different in Need(Elsevier Science Inc, 2023) Sıvış, Özce; Acar, MelikeThe current study investigated children's judgments on procedural justice and its outcomes when the candidates were equal in merit but different in need. A total of 88 children (41 girls and 47 boys) aged 7 to 11 years were individually interviewed (Mage = 8 years 9 months, SD = 14.065 months). Results showed that, regardless of age, children tended to give educational resources to the resource-poor candidates. However, children's welfare considera-tion of the resource-poor candidates increased with age. Children also made differentiated judgments based on the resource type and treated educational materials as more necessary than educa-tional experiences. Children's age and socioeconomic status (SES) were associated with this differentiation. Younger and high-SES children were more likely to view the outcome of procedural jus-tice (i.e., drawing a stick) for allocating an educational experience (i.e., summer camp) as fair when the result favored the resource -rich candidate. Overall, findings revealed that children do not use a unitary form of fairness in the procedural justice context. The shift from strict equality to welfare concerns continues to develop over middle childhood. (c) 2023 Elsevier Inc.

In conflictual situations where military force is used, it is important to create an impact in a short time to promote national interests by informing and influencing the public. This chapter will first introduce the fundamental tenets of public diplomacy to offer a conceptual framework to better understand its use during military conflicts. It will then explore the implementation of public diplomacy instruments by Turkish government during the “Operation Peace Spring”, which was launched in October 2019. The chapter will also assess the performance of Turkish public diplomacy in the face of the extent of criticism leveled against Türkiye from around the world, including allied countries and international organizations. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.Conference Object The Minimum Variance Distortionless Response Beamformer for Damage Identification Using Modal Curvatures(Association of American Publishers, 2023) Eroğlu, Uğurcan; Pau, A.This study presents a damage identification procedure in beams based on the use of beamforming algorithms, which are mostly utilized in inverse problems of source identification and image reconstruction. We choose the modal curvatures as observed quantities and compare the performance of the Bartlett beamformer, minimum variance distortionless response (MVDR) processor, and of a conventional objective function based on the modal curvatures. By means of a set of experiments, we show that the MVDR processor can overcome some of the difficulties encountered with other estimators, especially in cases of slight damage, or damage located between two sensors. © 2023, Association of American Publishers.

The obtained boron ore is presented to the utilization of many industrial branches such as insulation fiberglass and ceramic glazes, after washing, distribution, and classification according to the size but most of commercial applications of borates require the use of refined borates (Briggs in Kirk–Othmer encyclopedia of chemical technology, 2001). Approximately 4.2 million tons (2 million tons based on B2O3) of boron were produced globally in 2016. In worldwide B2O3-based boron production, Eti Maden (Turkey) ranks first with a 50% share, USA with 25%, and other countries with 25% are trailing Turkey (Bor Sector Report, Eti Mine, 2009). It is known that, during the production of boron containing chemicals, some of these are spreading to environment (Karahan et al. in J Colloid Interface Sci 293:36, 2006; Sahin in Desalination 143:35, 2002). Boron-containing wastes coming out of the exploitation facilities are generally solid and in small dimensions, and also in pulp state. The studies related with the evaluation of boron waste demonstrate that the most appropriate evaluation method for the boron waste is storing the waste without harming the environment or regaining the boron within the waste and making the remaining minerals including clay suitable for the utilization of appropriate sectors (Christogerou et al. in Ceram Int 35:447, 2009). Boron containing wastes generating from production facilities are suitable raw materials for appropriate sectors when environmental impacts are being taken into consideration, too. In this study, the effect of various amounts of boron waste added to the ceramic body on forming and firing processes have been analyzed. This study has been carried out in order to provide information for bringing in this inert potential resource to the advantage of the country’s economy. © 2023, The Minerals, Metals & Materials Society.Conference Object Citation - WoS: 8Citation - Scopus: 5Recognizing Non-Manual Signs in Turkish Sign Language(IEEE, 2019) Gökberk, Berk; Akarun, Lale; Aktaş, MüjdeRecognition of non-manual components in sign language has been a neglected topic, partly due to the absence of annotated non-manual sign datasets. We have collected a dataset of videos with non-manual signs, displaying facial expressions and head movements and prepared frame-level annotations. In this paper, we present the Turkish Sign Language (TSL) non-manual signs dataset and provide a baseline system for non-manual sign recognition. A deep learning based recognition system is proposed, in which the pre-trained ResNet Convolutional Neural Network (CNN) is employed to recognize question, negation side to side and negation up-down, affirmation and pain movements and expressions. Our subject independent method achieves 78.49% overall frame-level accuracy on 483 TSL videos performed by six subjects, who are native TSL signers. Prediction results of consecutive frames are filtered for analyzing the qualitative results.Article Citation - WoS: 6Citation - Scopus: 6Case Study on Seismic Behavior of Aseismically Designed Reinforced Concrete Frame Structures(2018) Oyguc, Evrim; Oyguc, Resat; Tönük, GökçeIn this study, the seismic performances of two aseismically designed plan-irregular reinforced concrete frame (RCF) households damaged during the October 23, 2011 Van earthquake are assessed. Since no strong ground motion recordings from the main shock were available, first, strong ground motion parameters of the event are evaluated and then compatible with these parameters suits of real records are selected and scaled to match with the event's simulated acceleration spectrum to be used in the analytical investigations. The results of previous reconnaissance studies, in which one of the present authors was involved, are then discussed. Capacities of the considered RCF's are determined applying a 3D single-run adaptive pushover procedure that is capable of considering the effect of plan irregularities. The performance assessment procedure based on the current 2007 Turkish Earthquake Code is then applied to these investigated buildings. Additionally, nonlinear dynamic time history analyses are carried out using the previously selected time histories. The hysteretic behavior of the considered buildings is examined as the consequence of the conducted analyses and considering the different suits of selected ground motions, the seismic response of the buildings is evaluated in terms of interstorey drifts. None of the buildings are found to satisfy the expected performance level. Moreover, the numerical results are found to have good correlation with the field observation results.Article The Impact of Organizational Gossip on Affective Organizational Commitment, Feelings of Loneliness, and Turnover Intention: a Mixed Methods Study(Cambridge Univ Press, 2025) Kucuk, Burcu Aydin; Ucok, Dilek Isilay; Konuk, HizirThis study examines the impact of organizational gossip on workplace outcomes, including affective organizational commitment, loneliness, and turnover intention, with a focus on differences between the public and private sectors. Using a mixed-methods approach, the research combines qualitative and quantitative data from surveys conducted with Turkish citizen partners and in-depth interviews with employees in both sectors. The findings reveal that positive gossip enhances social bonds and commitment, while negative gossip leads to loneliness and increased turnover intention, especially in the private sector where job insecurity is higher. The study introduces an integrated framework linking gossip dynamics to organizational processes. Practical implications suggest that managers should address negative gossip while promoting positive gossip to strengthen workplace relationships. This study highlights the dual role of gossip in shaping employee experiences and retention strategies.Article Citation - WoS: 2Citation - Scopus: 1Examining Factors Influencing Turkish Jewish Attitudes Towards the Armenian Genocide(Wiley, 2024) Kaymak, Özgür; Nefes, Türkay Salim; Gürpınar, DoğanThe most prominent issue influencing Turkish-Armenian relations is the international recognition of the Armenian genocide. However, there is a notable absence of empirical analyses regarding the perceptions of the genocide among the Turkish population. This study aims to fill this scholarly gap by exploring, for the first time, the perspectives of Turkish Jews. It analyses evidence collected from interviews conducted with 14 Turkish Jews, utilising Stanley Cohen's (2001) theoretical framework, which aids in delineating significant factors by a categorisation of types of acceptance and denial. The findings highlight a diversity of responses linked to political attitudes, which can be broadly categorised into Kayades and Avlaremoz mindsets. They also show that Turkish Jews' views on the Holocaust influence how they perceive the Armenian genocide. Additionally, the results indicate that Cohen's approach is useful in explaining non-denying responses. In conclusion, the study argues that Turkish Jews' perspectives appear to be strongly related to their stance towards the Turkish state and the Holocaust.Article Citation - WoS: 1Citation - Scopus: 1Determining and Evaluating New Store Locations Using Remote Sensing and Machine Learning(Tübitak, 2021) Ünsalan, Cem; Turgay, Zeynep Zerrin; Küçükaydın, Hande; Höke, BerkanDecision making for store locations is crucial for retail companies as the profit depends on the location. The key point for correct store location is profit approximation, which is highly dependent on population of the corresponding region, and hence, the volume of the residential area. Thus, estimating building volumes provides insight about the revenue if a new store is about to be opened there. Remote sensing through stereo/tri-stereo satellite images provides wide area coverage as well as adequate resolution for three dimensional reconstruction for volume estimation. We reconstruct 3D map of corresponding region with the help of semiglobal matching and mask R-CNN algorithms for this purpose. Using the existing store data, we construct models for estimating the revenue based on surrounding building volumes. In order to choose the right location, the suitable utility model, which calculates store revenues, shouldbe rigorously determined. Moreover, model parameters should be assessed as correctly as possible. Instead of using randomly generated parameters, we employ remote sensing, computer vision, and machine learning techniques, which provide a novel way for evaluating new store locations.Conference Object Citation - Scopus: 4Multi-View Reconstruction of 3d Human Pose With Procrustes Analysis(IEEE, 2019) Gökberk, Berk; Akarun, Lale; Temiz, HüseyinRecovery of 3D human pose from cameras has been the subject of intensive research in the last decade. Algorithms that can estimate the 3D pose from a single image have been developed. At the same time, many camera environments have an array of cameras. In this paper, after aligning the poses obtained from single images using Procrustes Analysis, median filtering is utilized to eliminate outliers to find final reconstructed 3D body joint coordinates. Experiments performed on the CMU Panoptic, and Human3.6M databases demonstrate that the proposed system achieves accurate 3D body joint reconstructions. Additionally, we observe that camera selection is useful to decrease the system complexity while attaining the same level of reconstruction performance.Article Citation - Scopus: 14Grounding Probability in Narrow Waterways(Cambridge University Press, 2020) Özlem, Şirin; Altan, Yiğit Can; Otay, Emre N.; Or, İlhanThe Strait of Istanbul is one of the world's busiest, narrowest and most winding waterways. As such, there is a high grounding probability for vessels. Although a number of grounding probability models exist, they have been deemed unsuitable by local maritime experts, due to their insufficient stopping distance criteria for narrow waterways. Thus, there is a need for a new model. This paper proposes a two-component grounding probability model that multiplies the geometric grounding probability (calculated with a kinematic-based model) with the causation probability (calculated with a specially designed Bayesian network). The geometric probability model is improved in terms of stopping distance parameters and the Bayesian network is crafted for narrow waterways. The model is then deployed with pre-determined parameters within the Strait of Istanbul to run risk analysis scenarios. The results, validated with actual grounding records, show that the causation probability is the key component for quantifying the probability of grounding in narrow waterways. If navigated without frequent evasive manoeuvres, grounding would be almost inevitable. Although this study focuses on the Strait of Istanbul, the proposed approach can be applied to research into grounding probability of vessels navigating through other waterways.

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.Article Citation - WoS: 7Citation - Scopus: 8Hematocrit Levels and Thrombotic Events in Patients With Polycythemia Vera: an Analysis of Veterans Health Administration Data(Springer, 2019) Parasuraman, Shreekant; Robyn Scherber; Jingbo Yu; Li Wang; Dilan Paranagama; Sulena Shrestha; Başer, OnurPatients with polycythemia vera (PV) have a high incidence of thrombotic events (TEs), contributing to a greater mortality risk than the general population. The relationship between hematocrit (HCT) levels and TE occurrence among patients with PV from the Veterans Health Administration (VHA) was evaluated to replicate findings of the CYTO-PV trial with a real-world patient population. This retrospective study used VHA medical record and claims data from the first claim with a PV diagnosis (index) until death, disenrollment, or end of study, collected between October 1, 2005, and September 30, 2012. Patients were aged ? 18 years at index, had ? 2 claims for PV (ICD-9-CM code, 238.4) ? 30 days apart during the identification period, continuous health plan enrollment from 12 months pre-index until end of study, and ? 3 HCT measurements per year during follow-up. This analysis focused on patients with no pre-index TE, and with all HCT values either < 45% or ? 45% during the follow-up period. The difference in TE risk between HCT groups was assessed using unadjusted Cox regression models based on time to first TE. Patients (N = 213) were mean (SD) age 68.9 (11.5) years, 98.6% male, and 61.5% white. TE rates for patients with HCT values < 45% versus ? 45% were 40.3% and 54.2%, respectively. Among patients with ? 1 HCT before TE, TE risk hazard ratio was 1.61 (95% CI, 1.03–2.51; P = 0.036). This analysis of the VHA population further supports effective monitoring and control of HCT levels < 45% to reduce TE risk in patients with PV.
