Publication Metadata only “And in the soup kitchen food shall be cooked twice every day”: gustatory aspects of Ottoman mosque complexes(Taylor and Francis, 2016) Department of Archeology and History of Art; Ergin, Nina Macaraig; Faculty Member; Department of Archeology and History of Art; College of Social Sciences and HumanitiesN/APublication Metadata only “Beware the young doctor and the old barber”: development and validation of a job age-type spectrum(Elsevier, 2021) Reeves, Michael Dennis; Fritzsche, Barbara Ann; Smith, Nicholas Anthony; Ng, Yin Lu; Department of Business Administration; Marcus, Justin; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 124653Taking a worker-centric approach, with evidence based on the experiences of working individuals, the current study examines the age-related stereotypes of jobs, the characteristics of age-stereotyped jobs, and the consequences of occupying them. In Study 1, we utilize samples of working adults from the US, Turkey, and Malaysia to establish validation evidence for a spectrum of 160 jobs (n = 123 raters per job). Study 1 findings indicate that entry-level jobs and jobs requiring manual labor or the use of technology are younger-typed, whereas senior level jobs and jobs requiring large investments in training or education are older-typed. The age-typing of jobs was found to be similar across countries for the vast majority of jobs. We then provide criterion validity evidence in Study 2, by testing the interactive effects of chronological age, job age-type, and sex on psychological age and perceived age and sex discrimination across samples of workers from these same three countries (n = 1469). Results upheld theoretical predictions based upon career timetables theory, prototype matching theory, and intersectional salience of ageism theory. The interactive effects of chronological age and job age-type were stronger for women than for men; the hypothesized patterns of effects were overall consistent for women but not for men.Publication Metadata only “Das recht auf vergessen" im rahmen des schutzes personenbezogener daten und die beurteilung in bezug auf die Türkei(İstanbul Kültür Üniversitesi, 2017) N/A; N/A; Önok, Rıfat Murat; Faculty Member; Law School; 178418Das “Recht auf Vergessen” hat in den letzten Jahren in der internationalen Literatur an Popularität gewonnen. Die Zahl der wissenschaftlichen Studien zu diesem Thema nimmt rasch zu. Wir sind jedoch weit entfernt davon, einen Konsens in der Lehre über die Grundlage dieses Rechts, sein Zweck und noch wichtiger über sein Inhalt und Umfang zu erzielen. Nach der Google-Entscheidung des EuGH, das hinsichtlich der Existenz (oder Nichtexistenz) eines solchen Rechts eine neue Dimension aufwirft und in Bezug auf Individuen an Bedeutung gewinnt, ist es nunmehr notwendig, das Recht auf Vergessen unter die Lupe zu nehmen. Es fällt auf, dass auch der “Yargıtay” damit begonnen hat, dieses Recht in seinen Entscheidungen zu nennen. In diesem Zusammenhang werden in diesem Aufsatz die Begriffsbestimmung, streitige Fragen in Bezug auf den Inhalt dieses Rechts, die Verbindung und Folgen der Google-Entscheidung mit diesem Recht, sowohl theoretische als auch praktische Fragen, die sich aus dem EUGH-Urteil und der Umsetzung eines solchen Rechts ergeben können, sowie eine Reihe von Fragen, die sich im Zusammenhang mit diesem Recht für die Türkei ergeben können untersucht. / Son yıllarda uluslararası literatürde popülarite kazanan kavramlardan biri“unutulma hakkı”dır. Konuya dair akademik çalışmaların sayısı hızla artmakla birlikte;hakkın dayanağı, hizmet ettiği amacı ve daha da önemlisi, tam içeriği ve kapsamı hakkın-da doktrinde görüş birliği sağlanmasına henüz uzağız. Buna rağmen, böyle bir hakkınvarlığının (veya yokluğunun) bireyler açısından önemi ve konuya yeni bir boyut kazandı-ran, Avrupa Birliği Adalet Divanı’nın Google kararı sonrasında, unutulma hakkının irde-lenmesi zorunluluk arz etmektedir. Yargıtay’ımızın da kararlarında kavrama yer vermeyebaşladığı dikkati çekmektedir. Bu bağlamda, çalışmada; kavramın tanımı, içeriğine dairtartışmalı hususlar, Google kararının bu hakla bağlantısı ve sonuçları, gerek ABAD kara-rından gerekse böyle bir hakkın uygulanmasından kaynaklanabilecek teorik ve pratiksorunlar, Türkiye açısından bu hakla bağlantılı birtakım meseleler incelenmiştir.Publication Metadata only “Do you feel like becoming a leader?” Emotions and the likelihood of self-nomination for leadership(Elsevier Inc., 2022) Department of Psychology; N/A; Aycan, Zeynep; Shelia, Salome; Faculty Member; PhD Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 5798; N/AN/APublication Metadata only “Doing What Matters in Times of Stress” to decrease psychological distress during Covid-19: a rammed controlled pilot trial(Wolters Kluwer Medknow Publications, 2022) Uygun, Ersin; Karaoğlan Kahiloğulları, Akfer; Department of Psychology; Department of Psychology; N/A; Acartürk, Ceren; Kurt, Gülşah; İlkkurşun, Zeynep; Faculty Member; Teaching Faculty; Master Student; Department of Psychology; College of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 39271; 368619; N/ADespite the increasing psychological distress during Covid-19, utilisation of face-to-face psychological interventions decreased profoundly. The aim of this study involving two parallel, two-armed pilot randomised controlled trials was to examine the effectiveness of a guided self-help intervention "Doing What Matters in Times of Stress" (DWM) in decreasing psychological distress in Turkish and Syrian participants. Seventy-four Turkish nationals and 50 Syrian refugee adults with psychological distress were randomly allocated to a DWM group or wait-list control group. The primary outcome measure was the Patient Health Questionnaire 9 postintervention. Secondary outcome measures were the Generalised Anxiety Disorder Scale, posttraumatic stress disorder (PTSD) Checklist for DSM-5, Generalized Self-Efficacy Scale and Acceptance and Action Questionnaire-II postintervention. Although this study was not powered to detect a significant effect for DWM postassessment between DWM and the control group, results showed a significant improvement in depression symptoms among Turkish participants in the DWM group (d = 0.46) and in PTSD symptoms among Syrian participants in the DWM group (d = 0.67) from pre- to postintervention assessment. These results indicate the potential of DWM to decrease mental health problems during the pandemic and importance of a fully powered, definitive controlled trial to examine its effectiveness both for the host community and refugees to reduce psychological distress during Covid-19.Publication Metadata only “O/F shift” in hybrid rockets(American Institute of Aeronautics and Astronautics, 2014) Toson, Elena; Evans, Brian; Department of Mechanical Engineering; Karabeyoğlu, Mustafa Arif; Faculty Member; Department of Mechanical Engineering; College of Engineering; 114595For most hybrid rocket systems, oxidizer to fuel ratio (O/F) changes over time due to 1) natural growth of the fuel port diameter and 2) oxidizer flow rate variations, if throttling is employed. This phenomenon, which is referred to as “O/F shift”, leads to a reduction in motor performance. Note that liquid or solid rocket motors are not subject to temporal O/F variations, which is wrongfully considered as one of the most critical disadvantages of hybrid rockets. In this paper, the effect of “O/F shift” is quantified for hybrid rocket motors. Analytical formulas for the temporal O/F variation and the overall c* efficiency drop associated with the variation has been derived for single circular port motors. It has been shown that for a typical motor, c* efficiency drop due to O/F variation is well below 0.2%, a value which is too small to be measured in an actual motor test. It is also shown that for a wagon wheel type multiport configuration (with triangular ports), efficiency drop is significantly worse than the single circular port case. Even for the multiport systems, the shift does not have a controlling effect on the overall efficiency of the motor. A number of strategies have been outlined to control the adverse effects of O/F variation in a hybrid rocket. For a single circular port design with limited throttling, no mitigation is required. For systems with deep throttling requirements, aft oxidizer injection seems like a viable strategy to retain a high level of overall efficiency.Publication Metadata only “Poor but achiever”: social capital, ethnicity, school achievement(Eğitim Araştırmaları Birliği, 2018) Department of Sociology; Çelik, Çetin; Faculty Member; Department of Sociology; College of Social Sciences and Humanities; 105104This study uses Bourdieu's social capital concept to analyze the impacts of the parental networks on the educational success of their children by comparing student-mother and dropout-mother interviewee pairs living in disadvantaged areas of Istanbul. The findings obtained from the research reveal that; (1) although they live in the same disadvantaged neighbourhoods, students continuing to attend school differ from school dropouts in terms of socioeconomic and ethnic terms; (2) school dropouts are predominantly from Kurdish and Roma families living in marginal poverty; (3) the network structures of the parents of school drop-outs and nondropouts significantly differ in the nexus of socioeconomic resources and ethnicity; and (4) differences in network structures favouring parents of those continuing to attend school are mobilized to improve the school success. This research argues that this differentiation between the two groups regarding opportunities and constraints may be the result of the historical memory of the ethnic groups who occupy differing positioning the ethnoreligious hierarchy of Turkish society. / Bu çalışma Bourdieu’nün sosyal sermaye kavramını kullanarak İstanbul’un dezavantajlı bölgelerinde yaşayan, halihazırda okula devam eden ve kısa bir süre önce okulu terk etmiş öğrenci ebeveynlerinin ağ yapılarını çocuklarının eğitim başarısına etkileri bakımından ayrıntılı olarak analiz etmektedir. Araştırmadan elde edilen bulgular şunlardır: (1) Her ne kadar aynı dezavantajlı mahallelerde yaşıyor olsalar da okula devam eden öğrenciler sosyoekonomik ve etnik açıdan okul terklerden ayrışmaktadır; (2) okul terkler ağırlıklı olarak marjinal yoksulluk koşullarında yaşayan Kürt ve Roman ailelerden gelmektedir; (3) okula devam edenlerin ve okulu terklerin ebeveynlerinin ağ yapıları sosyoekonomik ve etnisite olarak önemli derecede farklılaşmaktadır; ve (4) okula devam edenlerin ebeveynleri lehine olan ağ yapılarındaki farklılıklar, çocukların okul başarısını artırmak için mobilize edilmektedir. Araştırma, fırsat ve kısıtlara ilişkin bu grupsal farklılaşmaların onların Türkiye toplumda uzun süredir işgal ettikleri etnik konumlarının yarattığı bir toplumsal hafızadan kaynaklanabileceğini ileri sürmektedir.Publication Metadata only “Smart poisoning” of Co/SiO2 catalysts by sulfidation for chirality-selective synthesis of (9,8) single-walled carbon nanotubes(2016) Yuan, Yang; Karahan, H. Enis; Wei, Li; Zhai, Shengli; Lau, Raymond; Chen, Yuan; N/A; Yıldırım, Cansu; Birer, Özgür; Master Student; Researcher; Koç University Surface Science and Technology Center (KUYTAM) / Koç Üniversitesi Yüzey Teknolojileri Araştırmaları Merkezi (KUYTAM); N/A; N/A; N/AThe chirality-selective synthesis of relatively large (diameter > 1 nm) single-walled carbon nanotubes (SWCNTs) is of great interest for a variety of practical applications, but only a few catalysts are available so far. Previous studies suggested that S (compounds) can enhance the chirality-selectivity of Co catalysts in SWCNT synthesis, however, the mechanism behind is not fully understood, and no tailorable methodology has yet been developed. Here, we demonstrate a facile approach to achieve the chirality-selective synthesis of SWCNTs by the sulfidation-based poisoning of silica-supported Co catalysts using a mixture of H2S and H2. The UV-vis-NIR, photoluminescence, and Raman spectroscopy results together show that the resulting SWCNTs have a narrow diameter distribution of around 1.2 nm, and (9,8) nanotubes have an abundance of ∼38% among the semiconducting species. More importantly, the carbon yield achieved by the sulfided catalyst (2.5 wt%) is similar to that of the nonsulfided one (2.7 wt%). The characterization of the catalysts by X-ray diffraction, X-ray photoelectron spectroscopy, X-ray fluorescence, and H2 temperature-programmed reduction shows that the sulfidation leads to the formation of Co9S8 nanoparticles. However, Co9S8 nanoparticles are reduced back to regenerate metallic Co nanoparticles during the synthesis of SWCNTs, which maintain a high carbon yield. In this process, Co9S8 nanoparticles seemingly intermediate the production of Co nanoparticles with narrow size distribution. Due to the fact that the poisoning step improves the quality of the end-product rather than hampering the growth process, we have coined the process developed as “smart poisoning”. This study not only reveals the mechanism behind the beneficial role of S in the selective synthesis of relatively large SWCNTs but also presents a promising method to create chirality-selective catalysts with high activity for scalable synthesis.Publication Metadata only “Tell Me Your Story, I’ll Tell You What Makes It Meaningful’’: characterization of meaningful social interactions between intercultural strangers and design considerations for promoting them(Springer Science and Business Media Deutschland GmbH, 2021) N/A; Department of Sociology; Department of Media and Visual Arts; Department of Media and Visual Arts; Ramirez Galleguillos, María Laura; Eloiriachi, Aya; Serdar, Büşra; Coşkun, Aykut; PhD Student; Undergraduate Student; Master Student; Faculty Member; Department of Sociology; Department of Media and Visual Arts; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; College of Social Sciences and Humanities; N/A; N/A; N/A; 165306Positive meaningful interactions are encounters that promote positive attitudes and learning about others, which are needed to develop healthy social fabrics and cultural diversity. However, individuals tend to interact more with people like themselves often avoiding encounters with others that seem to be different, for example, with intercultural strangers. Though previous HCI work has been concerned with exploring meaningful experiences with products and technologies as a way of promoting product attachment, the field lacks studies exploring how design could facilitate intercultural MSI. Designing interventions to support intercultural MSI requires i) understanding what characteristics make these interactions meaningful and ii) how these characteristics can be addressed through design. In this study, we contribute to the literature by producing knowledge on these aspects. Based on an analysis of 56 real-life stories about intercultural MSI and an idea generation session with designers, we characterize intercultural MSI with four dimensions (outcomes, feelings, context, and elements) and we identify four design considerations to be taken into account when designing interventions to support intercultural MSI. Hence, our contribution is to formulate this knowledge while highlighting how the characteristics and perceptions of intercultural MSI can be applied to design new technologies that promote this kind of interaction. © 2021, Springer Nature Switzerland AG.Publication Metadata only “Working from home”: government initiatives to promote returning to Latvia amidst the Covid-19 pandemic(Springer, 2021) N/A; Lace, Agnese; PhD Student; Graduate School of Social Sciences; N/ADuring the early stages of the Covid-19 pandemic, the government of Latvia not only implemented a rather successful evidence-based approach to policy making regarding limiting the effects of the spread of the disease, but also designed a communication campaign ‘Ahead of the Curve’ to highlight this success and encourage diaspora members and others to consider Latvia as the place to settle down while ‘working from home’. In parallel, a return migrant organization initiated a debate in the Diaspora Consultative Council on the need for a clear approach to attracting digital nomads. This paper discusses the implications of these policy developments on the nature of Latvia's diaspora policy and return migration policy. The analysis explores the content of the campaign and policy debates to find the frames used to describe this new reality. It highlights the dependency of diaspora and return migration policy making on perceived economic growth or stability by policymakers.
