Generational Differences in the Acceptance of Consumer Robots: A Technology Acceptance Model Approach
(2026) Koç, Fatih; Giray, Caner; Yön, Belma; Okşar, Gülşah
The research addresses the growing integration of innovative technologies like consumer robots into daily life, particularly focusing on smart robotic vacuum cleaners, within the Technology Acceptance Model (TAM) framework. This study examines the increasing integration of innovative technologies, specifically consumer robots such as smart robotic vacuums, within the framework of the Technology Acceptance Model (TAM). The primary objective of the study is to investigate whether the strength of the structural relationships among perceived usefulness (PU), perceived ease of use (PEoU), attitude (ATT), and behavioral intention (INT) differs across generations (X, Y, and Z). In addition to this objective, we analyzed the direct and indirect effects among the variables, independent of generational differences. Data for the research were collected through an online survey administered to 357 participants. The data were evaluated using PLS-based structural equation modeling, specifically via multi-group analysis (MGA) and path analysis. Although generational mean perception levels for the respective variables remained statistically similar (based on ANOVA results), the strength of psychological transitions and effects among these variables varied significantly across generations. Results of the multi-group analysis indicate tha the structural impacts (path coefficients) of PEoU on ATT and of ATT on INT were significantly stronger in Generation Y than in other generations. Furthermore, within Generation Y, PEoU was found to influence ATT and INT, mediated by PU, while PU influenced INT, mediated by ATT. These findings offer critical insights for businesses seeking to understand the underlying mechanisms that drive the purchasing intentions of Generation Y consumers and to develop targeted strategies accordingly.
The awakening wine: A contextual and philosophical reading of khayyam’s rubaiyat
(2026) Kudret, Naib
This article offers a philosophical and contextual analysis of the metaphor of “wine” in Omar Khayyam’s Rubaiyat, challenging reductive interpretations that associate Khayyam solely with hedonism and secularism. Drawing upon a clearly defined corpus of quatrains authenticated by leading Khayyam scholars, including Abdolhossein Zarrinkoob, Abdolhamid Gheibi, and Abdülbaki Gölpınarlı, the study argues that Khayyam’s frequent invocation of wine functions as a profound metaphor for spiritual awakening, existential inquiry, and intellectual liberation. Rather than promoting literal intoxication, Khayyam employs wine to critique religious hypocrisy, emphasize the fleeting nature of life, and advocate for a conscious, wisdom-driven engagement with the present. The article examines the deep roots of wine symbolism within the Persian hamriyye (wine poetry) tradition, tracing its development from pre-Islamic ritual through Sufi mystical appropriation. It also examines how specific Western translators, including Edward FitzGerald, Friedrich Rückert, and J. B. Nicolas, have distorted Khayyam’s original metaphysical intentions by reinterpreting his symbolic motifs within culturally alien frameworks. By situating Khayyam’s poetry within its historical, linguistic, and intellectual contexts, and by engaging closely with authenticated Persian quatrains alongside their English translations, the study reclaims the richness of his symbolic language and restores the philosophical integrity of his worldview. Therefore, the article highlights how Khayyam’s quatrains transcend cultural and temporal boundaries, offering a timeless call to self-awareness, moral clarity, and existential authenticity.
Is Spirulina safe in terms of heavy metals? A public health risk assessment
(Springer Nature, 2026) Yaşar, Rüya Kuru; Aytekin, Özlem Üstün; Yılmaz, Şahin; Şahin, Fikrettin
Spirulina is a microalga/cyanobacterium widely consumed as a dietary supplement due to its high nutrient content and health benefits. While Spirulina is recognized for its contribution to daily mineral intake (e.g., iron, manganese, magnesium, and potassium), its ability to bind heavy metals raises safety concerns, particularly for vulnerable age groups. This study analyzed eight commercial Spirulina supplements (powder and tablet forms) consumed in Türkiye for heavy metal and macro-mineral content using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The health risks were assessed across various age groups, including pregnant and breastfeeding women. Significant variability was found in heavy metal and mineral concentrations among the supplements, with one sample (S3) exceeding acceptable Hazard Index (HI) levels for all age groups except adults. Notably, Spirulina supplements generally did not exceed the established dietary reference values or Codex limits for heavy metals, except in certain younger age groups where potential non-carcinogenic risks were observed. The results emphasize the importance of determining safe consumption levels for Spirulina and other algae-based supplements to mitigate risks while maximizing their nutritional benefits. Additionally, the findings highlight the need for public health guidelines to standardize Spirulina’s daily intake and labeling practices.
The relationship between health literacy, nutrition literacy, and beliefs and behaviors related to cancer prevention
(2026) Baş, Dilşat; Schoinas, Ezgi Sakar; Kestane, Vahibe Uluçay
Purpose The study evaluates the relationship between cancer prevention beliefs and health and nutrition literacy, and their impact on healthy eating practices. Methods A cross-sectional study was conducted with 811 voluntary adult participants aged 18 to 65. Data were collected via a five-section questionnaire assessing sociodemographic characteristics, cancer prevention beliefs, Mediterranean Diet Adherence Scale (MEDAS), Turkish Health Literacy Scale-32 (TSOY-32), and Self-Perceived Food Literacy Scale (SPFL). Correlations between participants’ mean scores across the scales were analyzed. Results The mean age of participants was 27.02 ± 10.14 years. Mean scores were 32.01 ± 10.86 for health literacy, 4.00 ± 1.71 for MEDAS, and 89.94 ± 15.46 for SPFL. Fatalistic beliefs about cancer prevention were held by 71.3% of participants. Adequate health literacy and high adherence to the Mediterranean diet were independent variables that increased fatalistic cancer prevention beliefs (p < 0.05), while being over 30 reduced them. Higher education level, perception of health status, adequate nutrition knowledge, and receiving nutrition information from healthcare professionals or dietitians increased health literacy (p < 0.05). Being married, following a special diet, and higher perceived food literacy increased adherence to the Mediterranean diet (p < 0.05). Female gender, regular exercise, and higher perception of health status increased perceived food literacy (p < 0.05). Conclusion Improving health literacy, education level, perception of health status, and nutrition knowledge, along with ensuring health information from professionals such as dietitians, is essential for enhancing fatalistic beliefs about cancer prevention.
Dimensional and cross-sectional compatibility of contemporary nickel–titanium files and their corresponding gutta-percha cones: A micro-computed tomography study
(Springer International Publishing, 2026) Sarkan, Cem; Haznedaroğlu, Faruk
This study aimed to evaluate the dimensional and sectional compatibility between contemporary nickel–titanium (NiTi) root canal instruments and their corresponding gutta-percha (GP) cones with variable tapers, and to assess their compliance with ISO and ADA standards using micro-computed tomography (Micro-CT). Four NiTi file systems (ProTaper Next X2, HyFlex EDM OneFile, Reciproc Blue R25, and WaveOne Gold Primary) were analyzed. Their compatibility with corresponding GP cones was assessed based on diameter and taper measurements at 1 mm intervals (D1 to D16). Measurements were performed using Micro-CT imaging, and data were analyzed using descriptive statistics, independent t-tests, and one-way ANOVA with Bonferroni post hoc tests (p<0.05). Compliance with International Organization for Standardization (ISO) and American Dental Association (ADA) standards was also assessed. The findings reveal significant dimensional discrepancies between files and GP cones, with GP cones generally exhibiting larger diameters. Reciprocating systems (WaveOne Gold and Reciproc Blue R25) demonstrated superior compatibility with GP cones compared to rotary systems (ProTaper Next and HyFlex EDM OneFile). GP cones adhered more closely to ISO and ADA standards than files. Significant mismatches were identified between NiTi instruments and their corresponding GP cones. Reciprocating systems showed better dimensional compatibility than rotary systems. These results highlight the need for careful evaluation of material pairing to ensure optimal clinical performance.
