The effect of job embeddedness and work engagement attitudes on organizational commitment: Academic staff
No full textBilgi toplumu, küreselleşmenin etkisiyle birlikte meydana gelen gelişmelere bağlı olarak birçok kuruluşun önemli görevler üstlenmesinde aracılık rolü görmüştür. Bu görevlerin en önemlilerini üstlenen kuruluşlardan biri de üniversitelerdir. Üniversiteler bilginin üretilmesi, kullanımı ve dağıtımı gibi temel görevleri yerine getirmekte; toplumun bilgi seviyesini yükselterek aydınlık bir yol çizilmesini sağlayan değerler bütünü olarak ifade edilmektedir. Bu nedenle; üniversitelerin öznesi, önemli yapıtaşları olarak nitelendirilen akademisyenlerin bulundukları örgüte olan bağlılıkları da fazlasıyla önem teşkil etmektedir. Çalışma; TR81 Bölgesi İllerindeki üniversitelerde çalışan akademisyenlerin işe gömülmüşlük ve işe adanmışlık tutumlarının örgütsel bağlılık üzerindeki etkisinin araştırılmasına yönelik olarak gerçekleştirilmiştir. Çalışmada, nicel veri toplama aracı olarak yüz yüze anket yöntemi kullanılmıştır. Toplanan veriler, SPSS istatistik programı ve Yapısal Eşitlik Modellemesi kapsamında Jamovi istatistik programı kullanılarak test edilmiştir. Analiz sonucunda; işe gömülmüşlük ve işe adanmışlık tutumlarının örgütsel bağlılık üzerinde anlamlı bir etkiye sahip olduğu ortaya çıkmıştır. Araştırmada ayrıca işe gömülmüşlük, işe adanmışlık ve örgütsel bağlılık ile demografik değişkenler arasında anlamlı fark olup olmadığı da tespit edilmiştir. Araştırma sonucunda işe gömülmüşlük, işe adanmışlık, örgütsel bağlılık ile demografik değişkenlerden cinsiyet, yaş, medeni durum, kıdem ve görev yapılan üniversitede geçirilen süre arasında istatistiksel olarak anlamlı bir fark bulunmamışken; eğitim durumu, çalışılan birim, akademik unvan ve görev yapılan üniversite değişkenleri arasında istatistiksel olarak anlamlı farklılık tespit edilmiştir. Gelecekteki araştırmacılar hem devlet hem de özel üniversitelerde farklı çalışmalar yapabilir ve sonuçların birbirleri ile karşılaştırılması önerilebilir. Ayrıca farklı sektör ve farklı kültürlerde daha geniş örneklem seçme yoluna gidilebilir. Yapılacak olan çalışmalar ile literatürün zenginleşmesine katkı sağlanabilir.The information society has played an intermediary role in many organizations undertaking important tasks depending on the developments that have occurred with the effect of globalization. One of the organizations that undertake the most important of these tasks is universities. Universities fulfill basic tasks such as the production, use and distribution of information; they are expressed as a set of values that increase the level of knowledge of the society and ensure that a bright path is drawn. Therefore; the commitment of academicians, who are considered as the subjects and important building blocks of universities, to the organization they are in is also of great importance. The study was conducted to investigate the effect of job embeddedness and work engagement attitudes of academicians working in universities in the TR81 Region Provinces on organizational commitment. In the study, face-to-face survey method was used as the quantitative data collection tool. The collected data was tested using SPSS statistics program and Jamovi statistics program within the scope of Structural Equation Modeling. As a result of the analysis; it was revealed that job embeddedness and work engagement attitudes have a significant effect on organizational commitment. In the study, it was also determined whether there was a significant difference between job embeddedness, work engagement, organizational commitment and demographic variables. As a result of the research, no statistically significant difference was found between job embeddedness, work engagement, organizational commitment and demographic variables such as gender, age, marital status, seniority and time spent at the current university; however, a statistically significant difference was found between variables such as education status, unit worked, academic title and current university. Future researchers can conduct different studies in both state and private universities and it can be suggested that the results be compared with each other. In addition, a wider sample selection can be made in different sectors and different cultures. The studies to be conducted can contribute to the enrichment of the literature
A Novel Solution to Enhance the Oxidative and Physical Properties of Cookies Using Maltodextrin-Based Nano-Sized Oils as a Fat Substitute
No full textThis study investigated the effects of maltodextrin-based nanoemulsions as fat substitutes in cookies, focusing on the oxidative stability and physical properties. Full-fat cookies (control, C) and 50% fat-reduced cookies with nanoemulsions (FC) were produced. The addition of nanoemulsions increased the cookie diameter from 46.3 mm (control) to 56.1 mm and reduced the thickness, resulting in a desirable texture. Initial hardness values (30.3 and 45.8 N) were lower in nanoemulsion samples and remained reduced over a 90 day storage period. Black cumin oil-loaded nanoemulsions provided the lowest peroxide values (1.7, 2.7, and 2.4 mequiv O2/kg), maintaining oxidative stability during storage. Final free fatty acid (FFA) values ranged from 0.23% to 0.44% after storage. Thiobarbituric acid (TBA) values indicated slower lipid oxidation, with values ranging from 1.47 to 2.51 mg MDA/kg on day 0 and increasing to a maximum of 4.13 mg MDA/kg by day 90 in fat-reduced cookies. Among the tested formulations, nanoemulsions enriched with black cumin oil demonstrated the highest effectiveness, yielding enhanced oxidative stability and improved quality characteristics. This study presents an innovative strategy by utilizing maltodextrin-based nanoemulsions containing naturally antioxidant-rich oils as fat replacers, offering a clean-label alternative to improve the oxidative resilience and physical quality of cookies.Y?z?nc?

Synergistic Effects of Low-Loading Cellulose Nanocrystals on the Mechanical, Morphological, Thermal, and Structural Properties of Epoxy Resins
No full textEpoxy resins have attracted considerable attention as versatile adhesives due to their structural stability, chemical inertness, and excellent resistance to oxidation. Their performance can be further enhanced through the incorporation of various additives designed for specific applications. In the present study, cellulose nanocrystals (CNCs), recognized for their high mechanical properties, were employed as a reinforcing agent. CNCs were incorporated into the epoxy resin at loading ratios of 0.0625%, 0.125%, 0.25%, and 0.5% to produce the nanocomposites. According to the obtained results, the lowest reductions observed in flexural and tensile strengths were 13% and 16%, respectively, while the highest increases in flexural and tensile modulus were 18% and 50%, respectively. Morphological analyses revealed that CNCs were not homogeneously distributed within the matrix, particularly at higher concentrations, where agglomeration likely contributed to the observed declines in mechanical performance. Thermogravimetric analysis (TGA) indicated a slight improvement in thermal stability at lower CNC loadings; however, thermal stability diminished at higher CNC concentrations. X-ray diffraction (XRD) analysis demonstrated that the neat epoxy exhibited the highest crystallinity index (CI, 62%), which progressively decreased with increasing CNC content, resulting in a more amorphous nanocomposite structure.Scientific and Technological Research Council of Turkey (TUBITAK) [1919B012112603]This study was funded through the 2209-A University Research Projects Support Program, provided by the Scientific and Technological Research Council of Turkey (TUBITAK), under Project Number 1919B012112603
Evidence-based nursing practices in relieving colic infants
No full textInfantile colic is defined as restlessness and crying spells that have been present for more than three weeks, at least three days a week, exceeding three hours a day, and cannot be explained for any other reason. It is a common reason for infants to be brought to the physician. Despite numerous suggested risk factors, its exact etiology remains unknown. There is no definitive method for treating infantile colic that can be considered both effective and safe. This condition causes anxiety for families and pediatricians alike, as the crying and restlessness in infants can suggest a range of potential underlying issues, including infections, gastrointestinal problems, trauma, nutritional issues, drug reactions, neurological causes, and cardiovascular diseases. Continuous crying in a baby can cause parents to feel frustrated, and inadequate, lose concentration and patience, fear harming the baby, and stop breastfeeding early. In this section, we discuss methods used to reduce the symptoms of infantile colic, such as massage, manipulative therapies (such as chiropractic, osteopathy, cranial osteopathy, craniosacral therapy, and cranial manipulation), dietary changes, and the use of probiotics and prebiotics (synbiotics). Additionally, parent education programs offer a range of techniques to help parents care for their infants. These techniques include calming strategies for crying infants, understanding infants' needs, general care recommendations such as sleep and feeding advice, stress reduction, and empathic counseling for parents. Understanding infants' needs is crucial for providing appropriate care. © 2025 Elsevier B.V., All rights reserved
I?KI?NCI?L METALURJI? PROSESİNDE FEO'NUN HIZLI KONTROLÜ VE PROSES AVANTAJLARI
No full textIn this study, the FeO content of slag in liquid steel and the oxygen levels in liquid steel were examined in a reference facility with a 100-ton capacity electric arc furnace, where secondary metallurgy processes are carried out in the ladle furnace. In the steel production process, one of the most critical parameters that must be continuously monitored in both liquid steel and slag is the amount of dissolved oxygen. Based on the measurements and analyses conducted, the aim was to enhance the efficiency and economic viability of the secondary metallurgy process, and the obtained data were evaluated. The study determined that high FeO content leads to increased alloy consumption due to oxidation losses, resulting in significant economic losses. On the other hand, it was observed that lower FeO levels contribute to a reduction in undesirable oxygen levels in liquid steel. Additionally, since lower FeO levels reduce the oxygen content in steel, a cleaner microstructure and improved mechanical properties in the final product were observed. It was also found that an increase in FeO content raises the oxygen content in liquid steel, thereby increasing oxidation tendency and steel contamination. Based on the findings, recommendations for optimizing slag management in steel production were presented. The clean liquid steel and improved mechanical properties achieved by a controlled FeO follow-up increase production efficiency, reduce costs and improve the performance of the final product. Low oxygen and inclusion content minimize defects during casting, enhance machinability, and improve weldability. Additionally, they contribute to the development of critical mechanical properties such as strength, toughness, and fatigue resistance, resulting in more durable and long-lasting materials. These factors elevate steel production quality, offering both economic and technical advantages.Bu çalışmada, 100 ton kapasiteli elektrik ark ocaklı bir referans tesiste, ikincil metalurji süreçlerinin yürütüldüğü pota ocağında, sıvı çelikteki cürufun FeO içeriği ve sıvı çeliğin oksijen seviyeleri incelenmiştir. Çelik üretim prosesinde, hem sıvı çelikte hem de cürufta sürekli olarak izlenmesi gereken en kritik parametrelerden biri çözünmüş oksijen miktarıdır. Yapılan ölçümler ve analizler sonucunda, ikincil metalurji prosesinin daha verimli ve ekonomik hale getirilmesi amaçlanmış ve elde edilen veriler değerlendirilmiştir. FeO içeriğinin yüksek olması durumunda meydana gelen alaşım yanmaları nedeniyle artan alaşım tüketiminin önemli ekonomik kayıplara yol açtığı belirlenmiştir. Öte yandan, düşük FeO seviyelerinin sıvı çelikte istenmeyen oksijen seviyelerinin azalmasına katkı sağladığı görülmüştür. Ayrıca düşük FeO seviyesinde çeliğin oksijen içeriği azaldığı için, daha temiz bir yapı ve nihai üründe daha iyi mekanik özellikler gözlemlenmiştir. FeO seviyesindeki artışın, sıvı çeliğin oksijen içeriğini de yükselterek oksitlenme eğilimini ve çelik kirliliğini artırdığı tespit edilmiştir. Elde edilen bulgular doğrultusunda, çelik üretiminde cüruf yönetiminin optimizasyonuna yönelik öneriler sunulmuştur. Temiz bir sıvı çelik ve iyileştirilmiş mekanik özellikler, üretim verimliliğini artırırken maliyetleri düşürmekte ve nihai ürün performansını iyileştirmektedir. Düşük oksijen ve inklüzyon içeriği, döküm sırasında kusurların azalmasını sağlamakta, işlenebilirliği artırmakta ve kaynaklanabilirliği iyileştirmektedir. Ayrıca, çeliğin mukavemet, tokluk ve yorulma dayanımı gibi kritik mekanik özelliklerini geliştirerek daha uzun ömürlü ve dayanıklı malzemeler elde edilmesine katkı sağlamaktadır. Bu faktörler, çelik üretiminde kaliteyi yükselterek hem ekonomik hem de teknik avantajlar sunmaktadır

No full textPurpose: The aim of this study was to determine the characteristics of adolescents' use of mobile health applications in the development of a healthy lifestyle. Design and methods: This was a descriptive comparative cross-sectional study. This study was conducted between October 21, 2024 and December 31, 2024 with 563 adolescents in seven schools in a province in the Western Black Sea Region of T & uuml;rkiye. Data were collected face-to-face using the Information Form on Children's Descriptive Characteristics and Mobile Health Applications and the Healthy Lifestyle Belief Scale for Adolescents. Student t-test and ANOVA were used to analyze the data. Results: The most frequent applications of the adolescents were physical activity themed applications (40.5 %) and healthy nutrition themed applications (33.3 %), respectively. Those who preferred physical activity-themed applications (61.82 +/- 0.70) had a higher mean score of Healthy Lifestyle Belief Scale for Adolescents than those who preferred Ministry of Health applications (43.54 +/- 2.91) (p < 0.001). Adolescents who used mobile health applications that allowed regular monitoring of their own health status (68.20 +/- 0.28) had a higher mean score of Healthy Lifestyle Belief Scale for Adolescents than those who used mobile health applications that allowed monitoring of sleep patterns (55.35 +/- 1.24) (p < 0.001). Conclusion: This study can provide information about the characteristics and advantages of mobile health applications used by adolescents, the features taken into account when downloading applications, and ensure that future interventions focus primarily on this system. Practice implications: Pediatric nurses can provide counseling for the individual health needs of adolescents and provide the right guidance to develop a healthy lifestyle. (c) 2025 Elsevier Inc.

Life satisfaction around the world: Measurement invariance of the Satisfaction With Life Scale (SWLS) across 65 nations, 40 languages, gender identities, and age groups
No full textThe Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset-with data collected between 2020 and 2022 -to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions. Multi-group confirmatory factor analysis indicated that configural and metric invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional SWLS model has universal applicability. Full scalar invariance was achieved across gender identities and age groups. Based on alignment optimisation methods, partial scalar invariance was achieved across all but three national groups and across all languages represented in the BINS. There were large differences in latent SWLS means across nations and languages, but negligible-to-small differences across gender identities and age groups. Across nations, greater life satisfaction was significantly associated with greater financial security and being in a committed relationship or married. The results of this study suggest that the SWLS largely assesses a common unidimensional construct of life satisfaction irrespective of respondent characteristics (i.e., national group, gender identities, and age group) or survey presentation (i.e., survey language). This has important implications for the assessment of life satisfaction across nations and provides information that will be useful for practitioners aiming to promote subjective well-being internationally
Öğretmenlik Kariyer Basamakları: Eğitimcilerin Bakış Açısıyla Yasal Düzenleme ve Uygulamalar
No full textThe main purpose of the research was to determine the opinions and suggestions of educators about the teaching career ladder and various dimensions of this practice. This study employed a mixed method sequential exploratory design. Data was collected using a survey, which included seventeen items as well as open-ended questions, developed by the researchers. The study employed a convenience sampling method. A total of one thousand one hundred seventeen educators participated in the study. Quantitative data was analyzed using descriptive statistics, namely frequency, percentage and Chi-square analysis. Qualitative data was analyzed through collaborative qualitative data analysis. The findings show that about half of the 1117 participants (N=520; 46,6%) were against the implementation of the Teaching Career Ladders, while 436 (39,0%) supported the current implementation. Qualitative analysis indicated that educators' suggestions on teaching profession law can be examined under two main themes: assessment and other issues. The research shows that teachers support the career promotion system but are against the system in current practice. Based on the findings in this study, it is suggested that teachers' opinions should be taken into consideration on regulations concerning their career ladders to provide more comprehensive laws and that consistency and continuity should be provided in terms of teachers' career ladders.Bu araştırmanın temel amacı, eğitimcilerin öğretmenlik kariyer basamakları ve bu uygulamanın çeşitli boyutları hakkındaki görüş ve önerilerini belirlemektir.
