(Dokuz Eylul University, 2025-01-31) Cerrahoğlu, Ece; Ünver, Buket; Ülkümen, İpek
Purpose: This study aims to examine the predictive role of individual sense of coherence, family sense of coherence and family health climate variables on university students' healthy lifestyle behaviors. Material and Methods: The sample of the study consisted of 371 university students aged 18-25. Sociodemographic Information Form, Healthy Lifestyle Behaviors Scale, Sense of Coherence Scale, Family Sense of Coherence Scale, Family Health Climate Scale were applied to the participants in order to collect the research data. Correlation analysis, independent two-sample t-test, one-way ANOVA test and multiple linear regression analysis were used to analyze the data. Results: According to the results of correlation analysis, a positive relationship was found between healthy lifestyle behaviors and individual sense of coherence, family sense of coherence and family health climate (p<.05). As a result of the multiple linear hierarchical regression analysis, after controlling for the sex variable, individual sense of coherence and family health climate variables significantly predicted healthy lifestyle behaviors (p<.05), while family sense of coherence had no significant predictive role on healthy lifestyle behaviors (p>.05). Conclusion: The findings show that individual sense of coherence, family sense of coherence and family health climate variables are essential on university students' healthy lifestyle behaviors. The sense of coherence provides significant protection in adopting health behaviors that will determine future health and well-being. Similarly, increasing healthy living practices within the family is of great importance for young people to adopt healthy lifestyle behaviors.
Tracing the evolution of ecommerce: historical foundations, impacts of the pandemic, and future directions
(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.
LuminaURO: a comprehensive Artificial Intelligence Driven Assistant for enhancing urological diagnostics and patient care
(Hayat Sağlık ve Sosyal Hizmetler Vakfı, 2025-05-29) Soylu, Tuncay; Topçu, İbrahim; Karaman, Muhammet İhsan; Tuzcu, Esra Melis; Kınık, Abdullah Harun; Güneren, Mustafa Sacit; Salman, Zeynep; Demir, Perihan; Beyzanur, Kaç
Aim: This study aims to develop and validate LuminaURO, a Retrieval-Augmented Generation (RAG)-based AI Assistant specifically designed for urological healthcare, addressing the limitations of conventional Large Language Models (LLMs) in healthcare applications. Methods: We developed LuminaURO using a specialized repository of urological documents and implemented a novel pooling methodology to search multilingual documents and aggregate information for response generation. The system was evaluated using multiple similarity algorithms (OESM, Spacy, T5, and BERTScore) and expert assessment by urologists (n=3). Results: LuminaURO generates responses within 8-15 seconds from multilingual documents and enhances user interaction by providing two contextually relevant follow-up questions per query. The architecture demonstrates significant improvements in search latency, memory requirements, and similarity metrics compared to state-of-the-art approaches. Validation shows similarity scores of 0.6756, 0.7206, 0.9296, 0.9223, and 0.9183 for English responses, and 0.6686, 0.7166, 0.8119, 0.9220, 0.9315, and 0.9086 for Turkish responses. Expert evaluation by urologists revealed similarity scores of 0.9444 and 0.9408 for English and Turkish responses, respectively. Conclusion: LuminaURO successfully addresses the limitations of conventional LLM implementations in healthcare by utilizing specialized urological documents and our innovative pooling methodology for multilanguage document processing. The high similarity scores across multiple evaluation metrics and strong expert validation confirm the system’s effectiveness in providing accurate and relevant urological information. Future research will focus on expanding this approach to other medical specialties, with the ultimate goal of developing LuminaHealth, a comprehensive healthcare assistant covering all medical domains.
Sağ popülist söylemde güvenlikleştirme ve yeniden yaratılan kırılganlık: Almanya, Fransa ve Hollanda örnekleri
(Kahramanmaraş Sütçü İmam Üniversitesi, 2025-04-30) Kaçar Aşcı, Fatmanur; Özdemir, Veli
Popülist söylemlerde güvenlik, esas olarak sıradan insanların kimliği ve bu kimliğe yönelik elitlerin dile getirmediği tehditler tarafından şekillendirilir. Popülist söylemlerde güvenlikleştirme dışlama siyaseti ve siyaset kurumunu etkisiz hale getirmeyle bağlantılıdır. Halka veya halkın kimliğine/kültürüne yönelik varoluşsal bir tehdit ancak popülist aktörün kasıtlı olarak saldırgan bir siyasi üslup kullanmasıyla önlenebilir ve bu üslup popülist aktörlerin kendileri tarafından popülist aktörün arkasında toplanmak için varoluşsal bir krize ihtiyaç duyulduğuna işaret eden bir aciliyet duygusuyla şekillendirilir. Ancak popülist söylemlerde güvenlikleştirme, Kopenhag Okulu'nun elitist ve yukarıdan aşağıya bir süreç olarak gördüğü geleneksel güvenlikleştirme yaklaşımına tam olarak uymamaktadır. Nitekim popülist söylemlerde güvenlikleştirme yukarıdan aşağıya ve aşağıdan yukarıya doğru olarak iki yönlü ortaya çıkmaktadır. Popülist söylemlerde güvenlikleştirme geleneksel güvenlik aktörlerini ve devlet elitlerinin otoritesini sorgulamakta ve başta siyasi elitler olmak üzere geleneksel kurumları halka tehdit olarak tanımlamaktadır. Bu çalışma, Avrupa'daki sağ popülist partiler arasında yer alan Almanya için Alternatif Partisi (AfD), Özgürlük Partisi (PvV) ve Ulusal Birlik Partisi (RN)'nin mültecileri halkın güvenliğine yönelik nasıl tehdit olarak tasvir ettiklerini incelemektedir. Çalışmanın dönemi olarak 2017-2022 yılları arasındaki seçim kampanya görselleri ve söylemleri seçilmiştir. Bu çalışmanın temel argümanı, sağ popülizmin, korunmaya ihtiyacı olduğu iddia edilen halka karşı popülist liderlerin söylem ve görsellerle hitap etmesiyle ayırt edilen ve süreklilik arz eden bir güvenlikleştirme tarzı olarak anlaşılabileceğidir. Ayrıca popülist güvenlikleştirme süreçleri çift yönlü bir olgu olduğu için mülteci sorununa siyasi bir çözüm bulunmasına katkıda bulunmamakta, aksine söz konusu ülkelerin toplumsal ve siyasi güvenliğini etkileyen yeni krizler ve kırılganlıklar yaratmaktadır. Bu bağlamda popülizmin farklı karakterizasyonları, güvenlikleştirme teorisi ve popülist söylemlerde güvenlikleştirme süreçleri açıklanmış, sağ popülist partilerin mülteci meselesini nasıl güvenlikleştirdiği konusu Müslüman ve gayrimüslim mülteciler örneği üzerinden analiz edilmiştir.
