Sosyal Tabakalaşmadan Örgütler Arası Tabakalaşmaya: Hiyerarşi Kavramının Kurumsal Dünyadaki Yansımaları

Kuramsal bir derleme olan bu çalışmada, sosyolojinin temel kavramlarından biri olan sosyal tabakalaşma olgusu kavramsal boyutlarıyla detaylıca ele alınmakta; ayrıca, tabakalaşma kavramının örgütler arası düzeydeki yansımaları incelenerek bu yaklaşıma literatür temelli bir katkı s...

Yield Stability and Multi-Trait Evaluation of Groundnut (Arachis hypogaea L.) Cultivars Across Mediterranean-Type Environments in Türkiye

Genotype × environment interaction (GEI) is a major constraint on reliable cultivar recommendation in groundnut (Arachis hypogaea L.), particularly across environments that contrast in temperature, rainfall, and crop duration. In this study, the magnitude and structure of GEI wer...

Sulfur and polymer coating on urea enhances antioxidant defense, nutrient balance, secondary metabolites, and nitrogen use efficiency in salt‑stressed wheat

Soil salinity is a growing threat to wheat productivity. This study evaluated whether different coated urea formulations– especially polymer-sulfur-coated urea (PSCU) – could help wheat cope with different salt stress levels: non-saline control (1.3 dS m − 1 , showing the natural...

Deep Learning-Based Classification of Military Aircraft Types from Satellite Imagery

Automatic classification of military aircraft in satellite imagery is a challenging problem with a high risk of error due to the limited pixel area of targets, variations in image resolution and illumination conditions, background complexity, and strong visual similarity among cl...

Fresh-semen proAKAP4 concentration predicts sperm cryotolerance independently of conventional semen quality across three goat breeds

Abstract Cryopreservation compromises sperm quality, yet conventional semen analysis poorly predicts which ejaculates will withstand freezing. proAKAP4, a sperm-specific structural protein, is a candidate freezability biomarker, but is usually measured after thawing. We tested wh...

How Does Authentic Leadership Affect Perceived School Effectiveness? The Moderating Role of Teacher Professional Collaboration

Although the effect of authentic leadership on perceived school effectiveness is recognized, how this relationship changes depending on teachers’ professional collaboration has been insufficiently examined. This study aims to determine the moderating role of teacher professional...

Life quality and depression in mothers of children with spina bifida: A cross-sectional study

Spina Bifida (SB) frequently manifests with neurological, orthopedic, and urological complications in children, which severely restrict the activities of daily living (ADL) for both the affected children and their families. This cross-sectional study aimed to evaluate how specifi...

Explainable Machine Learning for Methylene Blue Removal Under Irradiation: Assessing Nominal Cu-Loading in AC@NiO

The time-dependent removal performance under irradiation of activated-carbon-supported nickel oxide (AC@NiO) samples containing nominal Cu-loadings of 0%, 3%, 5%, 7.5%, and 10% was examined using experimental concentration data and an explainable machine-learning (ML) framework....

Uncovering the psychological mechanisms behind quarter-life crisis and suicide cognitions

Young adults may experience a quarter-life crisis due to challenges they face in education, work, and relationships. Individuals experiencing a quarter-life crisis face numerous mental health issues, including psychological distress, entrapment, hopelessness, and suicidal ideatio...

Shape speaks loud: a geometric morphometric perspective on veterinary osteology

Geometric morphometrics has created a significant field in the study of skeletal variation in veterinary osteology by providing a robust framework for investigating shape variation. This technique allows for the analysis of anatomical structures in a variety of biological context...

Digital tracking and developmental challenges: GPS technology in adolescent elite football

The increasing use of GPS-based performance-tracking technologies in elite adolescent sport raises important questions about their psychological and developmental effects. Yet limited research addresses how adolescent athletes interpret continuous digital feedback in relation to...

Effects of Proprioceptive Neuromuscular Facilitation-Based Reformer Pilates and Hatha Yoga on Functional Fitness, Balance, and Cognitive Performance in Older Women: A 16-Week Randomized Controlled Trial

Abstract Background Aging is associated with progressive declines in neuromuscular function, postural control, and cognitive performance, which may compromise functional independence. Mind–body exercise approaches such as Pilates and Yoga have been suggested as effective strategi...

Interdural dermoid cyst located in the posterior fossa: A rare pediatric case report

Background: Intracranial dermoid cysts are rare congenital lesions arising from ectodermal inclusions during neural tube closure. They are usually located along the midline and most commonly present as intradural lesions. Posterior fossa localization is uncommon in children, and...

Interplay between sports nutrition knowledge, lifestyle factors, and body mass index among regularly exercising university students: a cross-sectional study

This study aims to comprehensively examine the complex relationships among sports nutrition knowledge, nutritional status (macro- and micronutrient intake), body mass index (BMI), and lifestyle factors (smoking status, dietary habits including salt preference, daily water consump...

An Investigation of Students' Attitudes Toward the Mathematics Course

Abstract: This study aims to determine fourth-grade primary school students' attitudes toward the mathematics course and to examine whether these attitudes differ according to gender, achievement level, and self-perceived adequacy in mathematics. The study was designed using the...
