Ageism and glass ceiling: barriers to advancement for women in Turkish banking
(Suat Teker, 2024-07-30) Dönmez, Sena; Tuncay Çelikel, Aslı
Purpose- The Turkish banking industry is known for its dynamism, where customer issues demand swift resolution, decisions must be made expeditiously, and employees are persistently pressured to meet targets. This engenders a highly stressful and demanding work environment. This paper examines the role of ageism in this industry, emphasising how gender and age-related biases intensify the “glass ceiling” as a chronic syndrome for employees. The objective of the research is to comprehend the impact of these biases on women across different age groups. Methodology- In-depth interviews were conducted with 20 female banking employees in Istanbul, Turkey. The participants included managers and branch employees from 16 different banks. A convenient sampling method was employed, and participants were invited to respond to open-ended questions regarding their experiences and motivations. Findings- The banking sector is characterised by a high level of stress, tight deadlines and the pressure to achieve key performance indicators (KPIs), which can have a significant impact on the well-being of women employees across all age groups. The study revealed a generational divide in motivations and expectations. Younger women prioritised favourable work conditions and salary, while senior women expressed a desire for early retirement due to burnout. Despite this, women of all age groups articulated a desire for career advancement and recognition, underscoring the pivotal role of managerial support and transparent expectations for future success. While extrinsic rewards remained a primary motivator, intrinsic rewards also played a role. Additionally, generational differences in expectations regarding motivation were observed. Conclusion- The dissolution of the glass ceiling necessitates the creation of an environment wherein individuals from disparate generational cohorts are able to provide mutual support, and age-based discriminatory practices are reduced. The acknowledgement and remuneration of employees’ competencies and expertise, in conjunction with the promotion of collaborative endeavours, can facilitate the development of a more equitable and nurturing work environment.
Paternal acceptance as a mediator of the association between maternal acceptance and youth’s personality disposition
(Onur Alp Kayabaşı, 2024-06-30) Olgaç, Duygu; Şirvanlı Özen, Dilek
Drawing upon interpersonal acceptance-rejection theory (IPARTheory), the present study aims to explore the associations between perceived maternal acceptance and the seven personality dispositions most central to the theory (hostility, dependence, self-esteem, selfadequacy, emotional responsiveness, emotional stability, worldview), as well as the possible mediating role of paternal acceptance. Data were collected from 551 Turkish children (50.6% boys) aged 11 through 15 (M=12.78 years) using a random sampling method. Results showed that both maternal and paternal acceptance were significant predictors of six of the seven personality dispositions most central in IPARTheory (low hostility, positive self-esteem, positive self-adequacy, emotional responsiveness, emotional stability, and positive worldview). Additionally, results showed that paternal acceptance partially mediated the association between maternal acceptance and low hostility, positive self-adequacy, emotional responsiveness, emotional stability, and positive worldview.

(Işık Üniversitesi Yayınları, 2024-10-31) Okandan, Buse; Erdoğdu, Emel
Obsesif-kompulsif bozukluk (OKB), bireylerin iş, sosyal ve aile yaşantılarında ciddi problemlere yol açan, işlevselliklerini sınırlayan obsesyonlar ve kompulsiyonlarla karakterize edilen bir bozukluktur. OKB, psikolojik ve bedensel semptomlara ek olarak bilişsel işlevlerde de bozulmalara neden olabilmektedir. Bu bozuklukların temel nedenlerini anlamak ve uygun tedavi yöntemleri geliştirmek amacıyla kullanılan araştırma yöntemleri, teknolojinin ilerlemesiyle birlikte çeşitlenmektedir. Son yıllarda bilişsel işlevleri (dikkat, tepki ketleme, görsel-uzamsal yetenekler gibi ) incelemede etkili bir araç olarak görülen göz-izleme teknolojisi bu alanda giderek yaygınlaşmaktadır. Göz-izleme teknolojisi, göz konumu, hareketleri ve göz bebeği değişimlerini ölçme yeteneğine sahiptir. Bu çalışma, OKB’de göz-izleme yönteminin kullanımını ele alan güncel literatürdeki araştırmaları incelemektedir. 2010 ve Eylül 2024 tarihleri arasında yayınlanmış çalışmalara erişmek için Google Akademik, Pubmed, EBSCO EDS, Cambridge Journals gibi veri tabanlarında, Obsesif-Kompulsif Bozukluk, Eye-Tracking, Gözİzleme gibi terimler kullanılarak arama yapılmıştır. Derleme, göz izleme cihazları kullanarak OKB'de çeşitli bilişsel işlevleri ölçen 14 makaleyi içermektedir. Sonuçlar, göz-izleme teknolojisinin OKB’nin heterojen yapısına bağlı araştırma zorluklarını aşmada etkili olabileceğini, daha objektif veriler sağladığını ve geleneksel nöropsikolojik testlerle elde edilen bulguları desteklediğini göstermektedir.

(Işık Üniversitesi Yayınları, 2025-04-30) Alekhwan, Tasnim
This study sought to compare Saudi Arabia's and Türkiye's health systems from 1960 to 2020. A comparative approach was used, using historical data, such as demographic information, life expectancy, infant mortality rate, urban and rural population, and the number of health professionals and individuals per health professional. The budgets of the Ministry of Health were also reviewed. The state budget, gross domestic product, the number of hospitals and beds, and their distribution between each country's private and public sectors are also analyzed. The study reached several conclusions, including that Türkiye and Saudi Arabia have made major changes in health care to make it better and more accessible over the past 60 years. The way health care is paid for differs, as Türkiye has a universal system, and Saudi Arabia uses public and private insurance. Access to health care services has become easier now in both countries, but there are still problems in obtaining affordable and available treatment. Improving the quality of health care and maintaining patient safety are important focuses in both countries. They are investing in new infrastructure and technology. Health care systems in Türkiye and Saudi Arabia have their unique characteristics.

(Hayrettin İvgin, 2025-06-24) Kazancı, Dilara
2000’li yılların başlangıcı bir yandan kadınlara yeni hukuksal hakların tanındığı, diğer yandan kadına yönelik şiddet, kadınların iş gücüne katılımı gibi sorunların öne çıktığı bir dönem olmuştur. Kadınlar için toplumsal açıdan hem olumlu hem de olumsuz değişimleri barındıran 2000 ile 2016 yılları arasına odaklanılan bu çalışmada, kadına yönelik şiddetin izleyici sayısı milyonları aşan popüler Türk filmlerinde nasıl sunulduğunun çözümlenmesi amaçlanmıştır. Bu amaç doğrultusunda gişe rakamlarına göre en fazla izleyiciye ulaşan 100 film içerik (doküman) analizi yöntemiyle değerlendirilmiştir. Filmlerde kadın karakterlerin maruz kaldığı fiziksel, duygusal, cinsel ve ekonomik şiddet türleri incelenmiş ve davranışsal göstergeler üzerinden kodlanarak analiz edilmiştir. Filmlerde karakterlerin şiddet gördükleri ya da uyguladıkları mekanlar, ‘kamusal alan’ ve ‘özel alan’ ayrımıyla belirlenmiştir. Araştırmanın sonuçları, 100 filmin 83’ünde kadın karakterlerin, fiziksel, duygusal, cinsel ve ekonomik şiddet türlerinden bir veya birkaçına maruz kaldığını göstermiştir. İncelenen filmlerde en yaygın biçimde temsil edilen şiddet türünün duygusal şiddet olduğu belirlenmiştir. Duygusal şiddet %80’lik oranla, fiziksel (%38), cinsel (%14) ve ekonomik şiddetin (%7) toplamından (%59) fazladır. Filmlerde kadın karakterlere şiddet uygulayan kişiler sıklıkla partnerleri (%25) ya da eski partnerleri (%13) olmuştur. Kadınlara şiddet uygulayan kişiler arasında, erkek iş arkadaşlarının (%13) ikinci sırada gelmesi dikkat çekmiştir. Kadınların kamusal alanlarda şiddete maruz kalma oranlarının (%41) özel alanlara (%21) göre daha yüksek olduğu gözlemlenmiştir. Kadınların maruz kaldıkları ve uyguladıkları şiddet karşılaştırılmalı olarak incelendiğinde cinsel ve ekonomik şiddet oranlarındaki farkların, duygusal ve fiziksel şiddet oranlarındaki farklara göre daha yüksek olduğu görülmüştür.

(Bayburt Üniversitesi, 2025-01-29) Örendil, Emre
Electronic commerce, or ecommerce, has been a topic of interest particularly in the last years. While ecommerce activities are notably facilitated today, it has gone through notably different forms since its first seeds were planted. The COVID-19 pandemic was a crisis for most businesses but also an opportunity for some, especially for those who were able to pivot or transform their businesses with respect to the new needs of consumers. With the positive impact of the pandemic on ecommerce sector observed especially as of the second quarter of 2020, its trend has surpassed the expectations. This overperformance came with numerous sceptical questions about the future of ecommerce. This study investigates the historical evolution, pandemic-induced transformations, and future trends of ecommerce. It conveys a compilation of milestones through systematic literature review with a focus on the practicality. This paper provides with a timeline of the ecommerce history to bridge its evolution in the last 80 years by visualizing the phases it has been through along with its anticipated trend in the upcoming years. The studied data reveals how COVID-19 accelerated ecommerce growth and highlights its implications for global retail. The growth of ecommerce may slow down but it will endure its growth as online shopping has already become an indispensable habit.
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, Aslı
In 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.

Amaç- Döviz kurunda yaşanan dalgalanmalar yabancı para cinsinden vadeli işlem gerçekleştiren şirketleri kur riskine maruz bırakmaktadır. Kur riski işletmeleri uluslararası ödemeler dengesi, sermaye ve kredi akımları, yabancı para cinsinden borç ve alacaklar, hatta uluslararası ticari etkinliklere katılmasa dahi ulusal para biriminin değerinin değişmesinin sonunda olumlu ve olumsuz şekilde etkilemektedir. Bu nedenle işletmeler kur riskinden korunmak için çeşitli yöntemler kullanmaktadır. Bu çalışma ise firmaların karşı karşıya kaldığı döviz kuru risklerinin ölçümü ve yönetimine ilişkin bazı temel konuları, döviz kuru riskini ölçmede şu anda baskın olan metodolojileri ve kur riski yönetiminde geniş çapta kabul görmüş en iyi uygulamaları özetlemektedir. Bu araştırmanın amacı, döviz kurlarındaki hareketliliğin sebep olduğu kur risklerine karşı işletmelerin kullandıkları stratejileri tanıtmaktır. Bununla birlikte bu çalışmanın alt amaçları, işletmelerin finans yetkilililerin ünvanlarına ve işletmelerin büyüklüklerine göre döviz kuru risklerinden korunma araçlarından haberdar olma durumlarını, kullanım düzeylerini, bu araçları kullanmayanların kullanmamaktaki sebeplerini belirlemek, işletme içi stratejileri ve ekonomik riskten korunma stratejilerini de ortaya koymaktır. Yöntem- Araştırmanın ana kütlesini Marmara Bölgesinde faaliyet gösteren işletmeler oluşturmaktadır. Araştırmanın örneklemi ise Türkiye’de Marmara Bölgesinde dış ticaret yapan 200 işletmeden oluşmaktadır. Verilerin toplanmasında ise İşletmelerin İşlem Riskinden Korunmak İçin Uyguladıkları Stratejiler Ölçeği kullanılmıştır. Firmaların maruz kaldıkları kur riskinden korunabilmek için kullandıkları tekniklerin üzerinden elde edilen veriler tanımlayıcı istatistikler ile yorumlanmıştır. Bununla birlikte, elde edilen verilere tek yönlü ANOVA testi uygulanmıştır. Bulgular- Türkiye'nin Marmara Bölgesindeki 200 dış ticaret işletmesinden elde edilen verilere dayalı olarak, şirketlerin kur riskinden korunmak için kullandıkları yöntemlere dayalı betimsel istatistiklerin bulgularına bakıldığında şirketler için kur riski şirket sağlamlığı için önem arz etmektedir. Şirketlerin kur riskinden korunma araçları konusunda bilgili olduklarını ancak buna rağmen kullanmak konusunda çekimser davrandıklarını görmekteyiz. İşletmeler kur riskinden korunmak için çeşitli teknikler kullanmaktadır. Bununla birlikte, ANOVA testi ile işletmelerin finans yetkililerinin ünvanlarına ve işletme büyüklüklerine göre döviz kuru risklerinden işlem riskinden ve ekonomik riskten korunmak için uyguladıkları stratejiler incelendiğinde finans yetkililerinin ünvanlarına göre ve şirketlerin büyüklüklerine kullandıkları stratejiler, kullanım düzeyleri, haberdar olma düzeyleri ve ekonomik ve işlem riskinden korunma araçlarında değişkenlik olduğu görülmektedir. Sonuç- Kur risinden korunma araçları üzerine veri analizi uygulaması yapılan bu çalışmada, döviz kuru riskini yönetmek için işletmelerin karmaşık ve çeşitli stratejiler kullandığını göstermektedir. İşletmeler, döviz kuru riskine karşı koyabilmek ve karlılıklarını korumak için bu stratejilere başvurmak zorundadır. Bu bulgular aynı zamanda, döviz kuru riskinin yönetilmesinin işletmelerin finansal performansı ve işletme sağlamlığı üzerinde önemli bir etkisi olduğunu göstermektedir.

Decoherence is a major issue in quantum information processing, degrading the performance of tasks or even precluding them. Quantum error-correcting codes, creating decoherence-free subspaces, and the quantum Zeno effect are among the major means for protecting quantum systems from decoherence. Increasing the number of qubits of a quantum system to be utilized in a quantum information task as a resource expands the quantum state space. This creates the opportunity to engineer the quantum state of the system in a way that improves the performance of the task and even to protect the system against decoherence. Here, we consider a quantum thermalization machine and four-qubit atomic states as its resource. Taking into account the realistic conditions such as cavity loss and atomic decoherence due to ambient temperature, we design a quantum state for the atomic resource as a classical mixture of Dicke and W states. We show that using the mixture probability as the control parameter, the negative effects of the inevitable decoherence on the machine performance almost vanish. Our work paves the way for optimizing resource systems consisting of a higher number of atoms.
