Yayın Assessment of speech intelligibility during different teaching activities in classrooms with and without acoustic treatment(Elsevier Ltd, 2023-05) Şaher, Konca; Bulunuz, Mızrap; Kelmendi, Jonida; Nas, SezinThere is limited data for assessing speech intelligibility in real classrooms with realistic occupied noise levels and teacher's and students’ speech levels for different teaching activities in Turkish secondary school classrooms. This study investigates the effect of reverberation time (RT), occupied noise levels and signal-to-noise ratio (SNR) on speech transmission index (STI) in real classrooms for instruction and group work. Noise levels were measured and STI values were calculated in two secondary school classrooms with RT of 0.88 s and 2.73 s. During instruction situation, calculated mean STI values were 0.63 (classroom with acoustic treatment) and 0.29 (classroom without acoustic treatment) for normal voice effort and 0.65 (classroom with acoustic treatment) and 0.39 (classroom without acoustic treatment) for raised voice effort. During group work, STI values ranged from 0.50 to 0.74 in classroom with acoustic treatment and from 0.01 to 0.34 in classroom without any acoustic treatment. SNR of 15 dBA is only approached in classroom with acoustic treatment during instruction situation. The effect of increasing SNR on STI is prominent in the classroom without acoustic treatment which already has low SNR values. The present results show that the classroom with acoustic treatment will have good speech intelligibility for instruction with normal vocal effort and for group work with raised vocal effort at 3 m distance. However, the classroom with no acoustic treatment will have STI values in the range of bad and poor intelligibility. The present results confirm the impact of SNR and RT on speech intelligibility and shows that RT value of minimum 0.8 s is optimal to have good speech intelligibility in a secondary school classroom of approximately 250 m3 with a capacity of 18 students.Yayın Imagined contact facilitates acculturation, sometimes: contradicting evidence from two sociocultural contexts(Educational Publishing Foundation-American Psychological Assoc, 2019-10) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Piyale, Zeynep Ecem; Stathi, SofiaObjective: Imagined intergroup contact has been shown to be an effective tool to improve intergroup relationships in various settings, yet the application of the strategy among minority group members and across cultures has been scarce. The current research aimed to test imagined contact effects on minority group members' acculturation strategies (contact participation and culture maintenance), perceived discrimination, feelings of belongingness, and social acceptance across three studies conducted in the United Kingdom (Study 1) and Turkey (Studies 2 and 3). Method: The sample consisted of Eastern Europeans in Study 1 (N = 63) and Kurds in Study 2 and 3 (N = 66 and 210, respectively). Participants were randomly assigned to 1 of 2 conditions (control vs. imagined contact) and completed measures of acculturation, perceived discrimination, general belongingness, and social acceptance. Results: Findings showed that while imagined contact significantly reduced perceived discrimination and culture maintenance, and increased contact participation and social acceptance among Eastern Europeans (Study 1), it reduced social acceptance and contact participation among Kurds recruited from a conflict-ridden homogeneous setting (Study 2). With a larger and more heterogeneous sample of Kurds (Study 3), these effects occurred only among those with higher ingroup identification. Moreover, in all studies social acceptance mediated the effects of imagined contact on contact participation and perceived discrimination. Discussion. Findings offer important insights about the use of the imagined contact strategy among minority group members and imply the need to take into account the context-dependent nature of contact strategies.Yayın When imagining intergroup contact mobilizes collective action: The perspective of disadvantaged and advantaged groups(Pergamon-Elsevier Science Ltd, 2019-03) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Stathi, Sofia; Piyale, Zeynep EcemThe current studies aimed to reveal the potential role of imagined intergroup contact on collective action tendencies within a context of intergroup conflict. Study 1 (disadvantaged Kurds, N = 80) showed that imagined contact increased collective action tendencies and this effect was mediated by increased perceived discrimination and ethnic identification. Study 2 (advantaged Turks, N = 127) demonstrated that imagined contact also directly increased collective action tendencies, as well as perceived discrimination and relative deprivation among the advantaged group. No significant mediation emerged. At the same time, in line with literature, imagined contact led only the advantaged group members to display more positive outgroup attitudes. Findings suggest that in settings where ingroup identities and conflict are salient, imagined contact may not readily undermine motivation for social change among group members.Yayın Being tolerated and being discriminated against: Links to psychological well-being through threatened social identity needs(Wiley, 2020-12) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Verkuyten, Maykel; Koç, Yasin; Türnüklü, Abbas; Piyale, Zeynep Ecem; Bekmezci, EyüpWe investigated whether and how the experience of being tolerated and of being discriminated against are associated with psychological well-being in three correlational studies among three stigmatized groups in Turkey (LGBTI group members, people with disabilities, and ethnic Kurds, totalN = 862). Perceived threat to social identity needs (esteem, meaning, belonging, efficacy, and continuity) was examined as a mediator in these associations. Structural equation models showed evidence for the detrimental role of both toleration and discrimination experiences on positive and negative psychological well-being through higher levels of threatened social identity needs. A mini-meta analysis showed small to moderate effect sizes and toleration was associated with lower positive well-being through threatened needs among all three stigmatized groups.Yayın Cross-ethnic friendships, psychological well-being, and academic outcomes: Study of South Asian and White children in the UK(Psychology Press Ltd., 2017-03-04) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Kumashiro, Madoka; Rutland, Adam; Smith, Peter K.; Blumberg, Herbert H.We examined whether two interpersonal processes, self-disclosure and affirmation of ideal self, mediated the relationship between cross-ethnic friendships and psychological well-being and academic outcomes. We conducted a cross-sectional survey with 484 secondary school children (243 White European, 241 South Asian British; Mage = 11.10, 220 boys, 264 girls) recruited from 35 multiethnic classrooms. Results of multilevel structural equation modeling revealed mediational effects of self-disclosure between cross-ethnic friendships and psychological well-being for only South Asian children. Affirmation also mediated the association between cross-ethnic friendships and both psychological well-being and academic outcomes for South Asian children. For White European children, affirmation mediated the association between cross-ethnic friendships and psychological well-being. Further analyses demonstrated that self-disclosure resulting from cross-ethnic friendship quality facilitated affirmation, which in turn promoted both sets of outcomes. Findings demonstrate that cross-ethnic friendships in multiethnic settings contribute to well-being through the generation of positive interpersonal processes.Yayın Siyahi kahramanın yolculuğunda beyaz ırkın rolü(Işık Üniversitesi, 2021-04-30) Şentürk, Selim; Şeylan, Seher; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Sinema ve Televizyon Yüksek Lisans ProgramıAmerika Birleşik Devletleri’nde derin bir geçmişe sahip olan siyahilere yönelik ötekileştirme ve ayrımcılık Hollywood filmlerinin de konusu haline gelmiştir. ABD politik ve sosyal hayatında siyahilere yönelik ötekileştirme ve ayrımcılık, sinemaya yansırken, ayrımcılıkla mücadele eden siyahinin, giriştiği bu mücadeleyi çoğunlukla beyaz bir kurtarıcı yardımı ile kazandığı görülmektedir. Filmin kahramanı yolculuğunu tamamlarken bu yolculuğun başarı ile sonuçlanmasını sağlayan beyaz bir kurtarıcıdır. Bu çalışmada “Kahramanın Sonsuz Yolculuğu” yöntemi ile, 2000’li yıllardan sonra çekilen, siyahilere yönelik ötekileştime ve ayrımcılığı konu alan Akademi ödüllü The Help (2012, Taylor), 12 Yıllık Esaret (Mcqueen, 2014), Fences (Washington, 2016) ve Green Book (Farelly, 2018) filmleri üzerinden siyahi kahramanların dönüşümünde beyaz kurtarıcının rolü incelenmektedir.Yayın A qualitative study of women employees in banking regarding the context of gender inequality and the glass ceiling syndrome(Işık Üniversitesi Yayınları, 2025-04-30) Dönmez, Sena; Tuncay Çelikel, AslıIn this research, we aim to address the glass ceiling syndrome arising from inequalities in business due to individual and environmental pressures, focusing on understanding the barriers women employees face in advancing their careers. The theoretical framework is based on theories that explain gender dynamics, including gender role conformity, human capital, statistical discrimination, career ladder barriers, social exclusion, social closure, and gendered organizations. Mismatched preferences, conflict, boundary management, attribution biases, stereotypes, feminist approaches, and capability-based theories also support this framework. A country-specific analysis was conducted by examining the history of women’s labor force participation. Using convenience sampling, in-depth interviews were conducted with 20 white-collar female bank employees across 16 banks. Content analysis was used to explore the perceptions of female employees regarding the glass ceiling in the sector. The primary challenges hindering women’s advancement include stereotypical perceptions, sticky floors rooted in social roles, mismatched aspirations, ageism, communication conflicts, managerial biases based on marital status, and discomfort in the workplace. Future-oriented solutions are provided by exploring root causes. Managers must recognize that motherhood does not inherently impede women’s Professional capabilities. Comprehensive training and awareness programs are crucial for management and female employees to address the sticky floor phenomenon.
