The Turkish version of the haemodialysis self-managementınstrument: a study of validity and reliability
No full textAim: This study aims to adapt the ‘Hemodialysis Self-Management Instrument (HDSMI-18)’ to Turkish culture, and evaluate its psychometric properties. Background: Self-management plays a critical role in improving patients' adherence to treatment and quality of life; however, self-management assessment tools specific to haemodialysis patients are limited. Design: The research employed a methodological design. Methods: The data were collected with a total of 200 haemodialysis patients receiving haemodialysis treatment between 15 July and 15 August 2024. Content Validity Index, Exploratory and Confirmatory Factor Analyses, Cronbach's alpha, Test–retest reliability and item-total score correlation were used in data analysis. Results: The original HDSMI-18 consists of 18 items and four subdimensions (partnership, self-care, problem-solving, emotional management). However, the Turkish version of HDSMI-18 (HDSMI) comprises 17 items and introduces an additional fifth subdimension, ‘self-control’, alongside the four original subdimensions. The five-factor structure of the HDSMI demonstrated acceptable internal consistency and reliability. The scale's overall Cronbach's α coefficient was determined to be 0.77, with subscale coefficients ranging from 0.63 to 0.83. Conclusion: The HDSMI is a valid and reliable tool for assessing self-management behaviours among haemodialysis patients in the Turkish population

Ekolojik göç bağlamında edebi temsiller: Köpekli çocuklar gecesi ve gazap üzümleri
No full textThroughout human history people have been migrating from one place to another place for several reasons. Thus, the word ‘migration’ could be defined as process of the movement of people from one place to another. If the reasons why people have been moving could be listed, wars, economic reasons, political reasons could be considered the main motives for this movement. Another important reason which has been leading people to leave their own countries is the natural catastrophes such as fires, floods and earthquakes. In today’s world the total of all these disasters originating from the climate change are the main cause for the migration.İnsanlık tarihi boyunca, insanlar bir yerden başka bir yere çeşitli nedenlerle göç etmişlerdir. Bu bağlamda, "göç" kelimesi, insanların bir yerden başka bir yere hareket etme süreci olarak tanımlanabilir. İnsanların göç etmelerine neden olan faktörler sıralanacak olursa, savaşlar, ekonomik sebepler ve politik nedenler bu hareketliliğin başlıca motivasyonları arasında sayılabilir. Diğer bir önemli sebep ise, insanlar üzerinde büyük etkiler yaratan doğal felaketlerdir; yangınlar, seller ve depremler gibi. Günümüzde ise, iklim değişikliğinden kaynaklanan tüm bu felaketler, göçün en temel nedeni haline gelmiştir
Theoretical foundations and methods of stylistics
No full textDil, insan iletişiminin en temel aracı olmasına rağmen, yapısı ve işleyişi bakımından oldukça karmaşık
ve çoğu zaman yeterince anlaşılmamış bir olgudur. 20. yüzyılın başlarında Ferdinand de Saussure
tarafından temelleri atılan çağdaş dilbilim çalışmaları, dilin bilimsel yöntemlerle incelenmesini mümkün kılmış ve bu süreçte biçembilim (stylistics) adı verilen alt bir disiplin doğmuştur. Biçembilim, yazınsal metinlerin dilbilimsel yöntemlerle; yazarın dili kullanma biçimi, metindeki estetik yapı ve dilsel unsurların işlevi bağlamında nesnel olarak analiz edilmesini amaçlamaktadır. Bu disiplin, kimi kaynaklarda "üslupbilim" ya da "deyişbilim" olarak da anılmakta olup, yazarın bireysel anlatım tarzını ve metinle kurduğu estetik ilişkiyi çözümlemeye çalışır. Charles Bally'nin ve Leo Spitzer'in çalışmaları biçembilimin kuramsal temelini oluşturarak, bu alanın yazınsal çözümleme ve eleştiriyle ilişkisini güçlendirmiştir. Biçem bilimsel çözümleme; bir yandan yazarın psikolojik ve bireysel yönlerini ortaya koymayı, diğer yandan metnin dilsel estetiğini somutlaştırmayı hedefler. Bu çalışma, biçembilim disiplininin tanımını, tarihsel gelişimini ve yazınsal metinlerin incelenmesinde kullanılan temel yaklaşımları örneklerle ortaya koymayı amaçlamaktadır.Although language is the most fundamental tool of human communication, it remains a complex and often insufficiently understood phenomenon in terms of its structure and function. Contemporary linguistic studies, initiated by Ferdinand de Saussure in the early 20th century, enabled the scientific investigation of language and led to the emergence of a sub-discipline known as stylistics. Stylistics aims to analyse literary texts through linguistic methods, focusing on the author's use of language, the aesthetic structure of the text, and the function of linguistic elements in an objective and systematic manner. Also referred to as "style studies" or "linguistic stylistics" in some literature, this field seeks to uncover the individual expression of the writer and the aesthetic relationship embedded within the text. The works of Charles Bally and Leo Spitzer laid the theoretical foundations of stylistics and reinforced its connection with literary
criticism. Stylistic analysis aims both to reveal the author's psychological and personal traits and to concretize the linguistic aesthetics of the text. This study aims to present the definition, historical development, and methodological approaches of stylistics in the analysis of literary texts, supported by relevant examples
Exploring reciprocal fairness and return policies in ecommerce
No full textThis study explores how fairness-related concepts intersect with return policies in e-commerce through a bibliometric analysis of 498 Web of Science articles (2010–2024). Findings reveal that “e-commerce,” “trust,” and “fairness” dominate the discourse, with a marked surge in publications after 2019 and continued underrepresentation of countries like Türkiye. Co-occurrence and collaboration maps highlight thematic clusters around service recovery, privacy, and AI-driven pricing, as well as strong USA–China research ties. We conclude that return policies function as symbolic markers of reciprocal fairness and recommend integrating ethical, psychological, and operational perspectives when designing future return strategies
Climate change, extreme heat, and outdoor thermalcomfort in urban areas: Case of İzmir, Turkey
No full textRecently, environmental problems, urban population growth, the expansion of urban areas, and climate-insensitive planning practices have significantly increased the effects of the climate crisis in urban areas. As cities’ population increases, cities’ vulnerability to disasters also increases. The negative effects of the climate crisis and global warming on both socio-economic and socio-ecological ecosystems vary at different scales. On the other hand, urbanization practices and the current spatial structure of Turkish cities reduce the resilience capacity of cities against the climate crisis and increase their vulnerability. When the environmental and social pressures of the climate crisis rise, hazards such as floods, extreme heat, and urban heat island (UHI) effects turn into disasters in cities. To prevent this, the effects of the climate crisis and the resilience capacity of existing urban structures should be well understood. This study focuses on extreme heat and the UHI effect, which is a critical socio-spatial problem. It is seen that the recent literature on climate change and extreme heat mostly focuses on UHI as an urban vulnerability and an effect of urban morphology, but previous studies partially cover morphological indicators. This study differs from many studies by relating local climate zone mapping with site-based study design and a comprehensive morphological dataset. The case study focuses on İzmir, Turkey; the relationship between outdoor temperature recordings and urban typo-morphological features is examined by using multivariate regression analysis. The findings correspond to the detection of the effective size of greening and the importance of ventilation for cooling in relatively high temperature climatic zones

Dorothy Johnson's behavioral system model: nursing management of a case with acute myeloid leukemia
No full textAkut miyeloid lösemi (AML), yetişkin popülasyonda en yaygın lösemidir ve tüm vakaların yaklaşık %80'ini oluşturur. AML’de en sık görülen semptomlar; anemiye bağlı olarak gelişen halsizlik-yorgunluk, dispne ve aktivite intoleransıdır. Hastalığa ve tedavi sürecine bağlı olarak gelişen semptomlar bireylerin ve ailelerinin yaşam kalitesinde azalma, bireylerde aile içi rolleri yerine getirememe, benlik saygısında azalma, sosyal izolasyon gibi sorunlara neden olmaktadır. AML’nin tedavi ve bakım sürecinin uzun ve yıpratıcı olması sebebi ile hasta ve ailesinin ihtiyaçlarına bağlı olarak multidisipliner ve çok yönlü bakış açısı gerektiren bir hemşirelik planlamasına ihtiyaç duyulmaktadır. Bu aşamada bakım planlaması yapılırken çeşitli modeller hemşirelere rehberlik edebilmektedir. Dorothy E. Johnson’ın Davranışsal Sistem Modeli; bireyin hastalık ve tedavi sürecinde uygun davranışlar geliştirmesinin kişinin iyilik halini olumlu yönde etkileyeceğini savunmaktadır. Bu olgu sunumunda AML tanılı bir hastanın bakım planlamasında Davranışsal Sistem Modelinin klinik ortamda kullanılabilirliğini ortaya koymak amaçlanmıştır.Acute myeloid leukemia (AML) is the most common leukemia in the adult population, accounting for approximately 80% of all cases. The most common symptoms in AML are; weakness and fatigue, dyspnea, and activity intolerance due to anemia. Symptoms that develop due to the disease and the treatment process cause problems such as a decrease in the quality of life of individuals and their families, inability to fulfill family roles, decrease in self-esteem, and social isolation. Since the treatment and care process of AML is long and tiring for both the patient and their families, a nursing planning that requires a multidisciplinary and versatile perspective is needed depending on the needs of the patient and her/his family. While planning care at this stage, various models guide nurses in this process. Dorothy E. Johnson's Behavioral Systems Model; It is argued that the individual's developing appropriate behaviors during the illness and treatment process will positively affect the person's well-being. In this case report, it is aimed to demonstrate the usability of the Behavioral System Model in the care planning of a patient with AML in the clinical setting
Enhancing biogas production efficiency through physical, chemical, thermal, and hybrid pre-treatment of olive mill wastewater
No full textIn this study, various pre-treatment methods were applied to enhance the biogas production efficiency of olive mill wastewater (OMW) collected from the decanter outlet of an olive oil mill operating with a three-phase system. The effects of ultrasonic (US), chemical (HNO₃), microwave (MW), and their combinations on the anaerobic digestion of OMW were evaluated. While HNO₃ pre-treatment alone and in combination with other methods improved biogas production efficiency, MW pre-treatment alone significantly reduced biogas yield. The highest volumetric cumulative biogas production of 231.5 mL (1.78 mL Biogas/gVSd) was achieved in the hybrid HN20 + US10 pre-treated sample, where HNO₃ was applied at 20 % of the total solids in raw OMW, followed by US pre-treatment for 10 min. The total phenol and chemical oxygen demand (COD) removal percentages for the HN20 + US10 pre-treated sample were determined as 25.9 % and 77.2 %, respectivel
Exploring patient experiences of telehealth in palliative care: a qualitative meta-synthesis based on mishel's uncertainty in illness theory
No full textBackgroundThis study aims to conduct a systematic synthesis of qualitative research exploring patient experiences with telehealth in palliative care and to evaluate the implications of these experiences through the lens of Merle Mishel's Uncertainty in Illness Theory.
MethodsTen qualitative studies published between 2015 and 2025 were analyzed. The literature review was conducted using the SPIDER strategy, with quality assessment performed via the JBI Critical Appraisal Checklist for Qualitative Research. Thematic analysis was carried out using MAXQDA software.
ResultsThe findings were synthesized into 3 meta-themes in accordance with Mishel's framework. Telehealth was found to facilitate access to information, save time and energy, and offer comfort and safety. However, uncertainty regarding technology use and emotional support needs were more pronounced in elderly and terminally ill patients.
ConclusionWhile telehealth applications offer significant advantages in palliative care, individual and contextual factors must be considered. In line with Mishel’s theory, access to information and patient involvement are key elements in managing uncertainty
