Bridging resource dependence theory and resource-based view: a theoretical synthesis
No full textPurposeThe aim of this study is to evaluate the resource dependence theory (RDT) and the resource-based view (RBV), their explanatory framework and strategy perspective, and to provide theoretical implications on how they can complement each other. Design/methodology/approachIn this study, RDT and RBV are compared based on their explanatory framework and the meaning they attribute to strategy. This is followed by a theoretical discussion or implication that draws on the basic explanations and arguments of these approaches and provides insights into the other side. FindingsWe have found that RDT's intra- and inter-organizational dependence explanations can be used as a mechanism for RBV to explain the process by which firms acquire, develop or possess resources and capabilities that provide a sustainable competitive advantage. On the other hand, our findings suggest that the RBV concepts of firm-specific resources, firm-level dynamic capabilities and dynamic managerial capabilities may offer new insights for the management of dependencies in RDT. Originality/valueThis study is the first theoretical work to discuss how RDT and RBV can complement each other and potentially extend the boundaries of these frameworks. It contributes to the organization theory and strategic management literature in this context
HUKUK MAHKEMESİNİN BEKLETİCİ SORUN KARARI ÜZERİNE CEZA MAHKEMESİNDE VERİLEN HÜKMÜN AÇIKLANMASININ GERİ BIRAKILMASI KARARININ ETKİSİ
No full textMahkemenin önüne gelen uyuşmazlıkta karar verebilme- si, başka bir mahkeme veya idarî merciin kararına bağlıysa bekletici sorun kurumu gündeme gelir. Bekletici sorun kararı yalnızca hukuk mahkemeleri için verilmez, ceza mahkemesi kararlarının da beklen- mesi mümkündür. Zira bazı ceza mahkemesi kararları, hukuk mahke- mesi açısından bağlayıcı nitelik taşır. Kararı beklenen ceza mahkeme- si, farklı şekillerde hüküm tesis edebilir. Söz konusu mahkeme, sanık hakkında bir mahkûmiyet kararı verip bu kararın açıklanmasını, yani hukukî sonuç doğurmasını da engelleyebilir. Hükmün açıklanmasının geri bırakılması olarak isimlendirilen bu kararın, hukuk mahkemesi açısından bağlayıcı olup olmadığı tartışılmalıdır. Kanun koyucu, Ana- yasa Mahkemesi’nin iptal kararı üzerine, hükmün açıklanmasının geri bırakılması kurumunu -bazı değişikliklerle- yeniden ihdas etmiş- tir. Bu kanundan önce verilen hükmün açıklanmasının geri bırakılma- sı kararlarının hukuk mahkemeleri tarafından bağlayıcılığı meselesi, -azalarak da olsa- bir süre daha güncelliğini koruyacaktır. Bu nedenle öncelikle bu dönemde verilen kararlar açısından değerlendirme yapı- lacaktır. Öte yandan, bahsedilen değişiklikler, hükmün açıklanması-nın geri bırakılması kararlarının hukuk mahkemesinde bağlayıcı olup olmadığı tartışmasını etkileyeceğinden, konunun bu yönüyle de ele alınması gerekir
The synthesis, characterization, DNA binding features and investigation of in vitro properties of new morpholine containing zinc (II) phthalocyanines
No full textThe novel peripheral and non-peripheral tetra triazole linked morpholine substituted phthalocyanines were synthesized via multistep reactions. The target zinc (II) phthalocyanines were obtained by the cyclotetramerization reaction of precursor nitriles containing triazole linked morpholine and zinc(II)acetate. And then, the synthesized zinc phthalocyanine compounds were made water-soluble with methyl iodide in chloroform. These newly synthesized phthalonitriles and related phthalocyanines have been characterized by a combination of 1H and 13C NMR, FT-IR, UV-vis, elemental analysis and MS spectral data. The DNA binding activities of Q-np-ZnPc and Q-p-ZnPc were assessed by UV-vis absorption titration, thermal denaturing and viscosity experiments, and the complexes were detected to bind to DNA via an intercalative binding mechanism. Besides, the antiproliferative effects of water-soluble zinc (II) phthalocyanines (Q-p-ZnPc and Q-np-ZnPc) were investigated in lung cancer cell lines. Our findings show that Q-p-ZnPc and Q-np-ZnPc significantly inhibit the cell proliferation of the lung cancer cell lines.Pamukkale University Research Fund [2021FEBE032]This study was supported by Pamukkale University Research Fund with project number 2021FEBE032
Classification of Welch Periodograms Using Deep Learning Methods: A Case Study on the Prediction of Sleep Apnea
No full textThis study proposes a novel approach for the diagnosis of sleep apnea using deep learning analysis of Welch Pediograms derived from electrocardiogram (ECG) signals. Despite affecting between 3% and 17% of the general adult population, depending on diagnostic criteria used, sleep apnea remains underdiagnosed due to limitations in traditional diagnostic methods, particularly polysomnography, which is costly, requires specialized facilities, and may disrupt natural sleep patterns. Our research addresses these challenges by developing an automated diagnostic system that analyzes frequency spectrum variations in RR intervals through Welch Pediograms. These visualizations, derived from Holter monitor recordings, effectively capture the characteristic frequency-domain changes in heart rate variability associated with sleep apnea episodes. Using Convolutional Neural Networks (CNNs), our methodology processes these spectral representations to identify patterns indicative of sleep apnea. This approach offers significant advantages including non-invasive monitoring, home-based testing capability, and improved patient comfort. Our findings contribute to both the methodological development in sleep medicine and the practical implementation of accessible diagnostic tools for sleep apnea, potentially improving early detection rates and patient outcomes.İzmir Bakırçay University Artificial Intelligence in Health Application and Research Centr
Psychometric characteristics of the Turkish version of the Professional Communication Questionnaire for the Operating Room
No full textBackground Effective professional communication is essential to ensure patient safety in the operating room (OR). The present study was conducted to adopt the Professional Communication Questionnaire for the Operating Room (PCQOR) into Turkish. Methods This methodological study involved 226 healthcare professionals (HCPs) in the OR. Data were collected using the individual information form and the PCQOR. The data were analyzed for linguistic, content, and construct validity and Cronbach's alpha test. Results The total variance of the scale with 34 items and three sub-dimensions was determined as 57.896%. The Cronbach's alpha coefficient of the scale was 0.936. The Cronbach's alpha values of the sub-dimensions were 0.956 for mutual respect and trust, 0.874 for team conflict and 0.866 for ethical competence. Item-total item correlations ranged from 0.187 to 0.829 to p < 0.01. Conclusions The PCQOR is a valid and reliable measure for the Turkish HCPs working in the OR
The impact of digitalization on independent audit practices
No full textDijitalleşme, günümüzde aktif olarak tartışılan konuların başında gelmektedir. Büyük veri ve veri analitiği, blokzincir, yapay zeka ve robotik süreç otomasyonu en çok ortaya çıkan teknolojilerdendir. Bağımsız denetim, bir şirketin finansal tablolarının ve iç kontrol sisteminin bağımsız denetçi tarafından objektif bir şekilde incelenmesidir. Bağımsız denetçi, finansal tabloların önemli yanlışlık içerip içermediğine ve iç kontrol sisteminin etkin bir şekilde tasarlanıp tasarlanmadığına ilişkin makul bir güvence elde etmek üzere, finansal tabloları ve iç kontrol sistemini objektif bir değerlendirmeye tabi tutar. Bu çalışma, dijitalleşme bağlamında, yeni teknolojilerin belirli bir süreç için en elverişli mesleklerden biri olan denetim mesleğine getirdiği algılanan faydaları ve zorlukları araştırmayı amaçlamaktadır. Profesyonel denetçileri kapsayan bu çalışmada nitel araştırma yöntemlerinden görüşme tekniği kullanılmıştır. 20 denetçi ile yarı yapılandırılmış görüşme gerçekleştirilmiştir. Bağımsız denetimin dijitalleşme ile entegrasyonu bağlamında ortaya çıkan faydalar olarak denetim kalitesi, esnekliği ve verimliliğinde iyileşme, artan güven faktörü ile itibar artışı ve beklenti boşluğunun azalması başlıkları ön plana çıkmıştır. Yeni denetçi profili ve değişime karşı direnç denetimde dijitalleşme için zorluk teşkil eden iki faktör olarak tanımlanmıştır. Sonuç olarak bu çalışmanın ampirik bulguları, denetçilerin dijitalleşmenin gelecekte daha da yaygınlaşacağı ve dijitalleşmenin önceki çalışmalarda iddia edildiği gibi iş fırsatlarının kaybına yol açmayacağı öngörülmektedir.Digitalization is one of the most actively discussed topics today. Big data and data analytics, blockchain, artificial intelligence, and robotic process automation are some of the most emerging technologies. An independent audit is an objective examination of a company's financial statements and internal control system by an independent auditor. The independent auditor conducts an objective evaluation of the financial statements and the internal control system to obtain reasonable assurance about whether the financial statements are free from material misstatement and whether the internal control system is designed effectively. In the context of digitalization, this study aims to explore the perceived benefits and challenges that new technologies bring to the auditing profession, which is one of the most relevant professions in this process. In this study covering professional auditors, interview technique, one of the qualitative research methods, was used. Semi-structured interviews were conducted with 20 auditors. As the benefits that emerged in the context of the integration of independent auditing with digitalization, the titles of improvement in audit quality, flexibility and efficiency, increased reputation with increased trust factor and reduction of expectation gap came to the fore. The new auditor profile and resistance to change were defined as two factors that constitute a challenge for digitalization in auditing. As a result, the empirical findings of this study predict that auditors will become more widespread in the future and that digitalization will not lead to loss of job opportunities as claimed in previous studies
Luminescence enhancement and thermal stability of alkali co-doped Eu3+: LaMgB5O10 phosphors
No full textEu3+-activated LaMgB5O10 (LMBO:Eu3+) phosphors were synthesized and systematically investigated to elucidate the role of alkali co-doping (Li+, K+) on their structural and luminescence properties. XRD, Raman, and FTIR analyses confirmed the phase purity and revealed subtle lattice distortions upon alkali incorporation, while SEM/ EDS verified homogeneous dopant distribution. Photoluminescence spectra are dominated by the characteristic 5D0-*7FJ transitions of Eu3+, with alkali ions inducing pronounced modifications in band distribution and emission intensity. Li+ co-doping yields a moderate enhancement and redistributes oscillator strength toward the 5D0-*7F4 transition, whereas K+ co-doping produces nearly an order of magnitude increase in far-red emission. Judd-Ofelt analysis provided intensity parameters (522, 524, 526), radiative lifetimes, and quantum efficiencies, highlighting the impact of alkali-induced site symmetry perturbations. Temperature-dependent PL measurements revealed distinct quenching and anti-thermal quenching (ATQ) behaviors: undoped Eu3+ exhibited conventional quenching with an activation energy of 0.404 eV, K+ co-doping reduced the barrier to 0.205 eV and triggered moderate ATQ above 470 K, while Li+ co-doping produced strong ATQ with emission intensity increasing nearly fourfold at 550 K. These findings demonstrate that alkali co-doping not only enhances far-red emission at room temperature but also stabilizes or even amplifies luminescence at elevated temperatures, making LMBO:Eu3+,M+ phosphors promising candidates for high-power pc-WLEDs and plant-growth lighting.Pamukkale University under BAP Project [2025.

Intra-household bargaining, resource allocation and cost of gender-based violence in Egypt: the role of asset ownership and gender role attitudes
No full textThis study explores the intra-household inequalities in Egypt, considering the gender role attitudes, female asset ownership and the domestic violence wives experience from their husbands. We apply a standard intra-household collective model and estimate the spouses’ labour supply equations. The empirical analysis relies on the Egypt Economic Cost of Gender-Based Violence Survey (ECGBVS) conducted in 2015. The cost may reach 2,500 Egyptian pounds per year if women have undergone any form of domestic violence from their partner, including physical, psychological, or sexual abuse. On the other hand, female asset ownership empowers women and enhances their bargaining power. The findings may provide insights on the development of policies, particularly about welfare indicators and actions aimed at reducing poverty. Intimate partner abuse can also hinder women’s participation in the labour market, leading to increased absenteeism, less productivity, and lower income. © 2025 Elsevier B.V., All rights reserved
Relationship between resilience, secondary traumatic stress and work-related factors among mental health professionals
No full textObjectives: Resilience is the ability to maintain or rapidly recover mental health under stress. Mental health professionals are often exposed to workplace stress through violence, emotional labor, restrictions, and traumatic stories. Secondary traumatic stress results from being affected by others' traumatic experiences. Examining the relationship between resilience and secondary traumatic stress among mental health professionals is therefore essential. Methods: This descriptive study was conducted between February and April 2022. Data were collected using the Personal Information Form, the Resilience Scale for Adults, and the Secondary Traumatic Stress Scale. Participants included 212 psychiatric and mental health nurses, 28 psychiatrists, 14 psychologists, and six social workers. Results: A significant positive relationship was found between resilience and secondary traumatic stress. The regression model, including secondary traumatic stress, gender, educational status, willingness to work in mental health, job satisfaction, and unit of work, significantly predicted resilience. Conclusion: Secondary traumatic stress and work-related factors, such as willingness and satisfaction with working in mental health and the unit of work, were found to play an essential role in resilience. Institutional support and supervision may strengthen resilience, while reducing secondary traumatic stress can enhance motivation and wellbeing. Institutions are recommended to implement strategies that address these factors to improve both resilience and professional effectiveness
Pnömotorakslı yenidoğan olguların altta yatan akciğer patolojileri açısından değerlendirilmesi
No full textAmaç: Bu çalışmada çeşitli solunumsal sorunlar nedeniyle yenidoğan yoğun bakım ünitesinde izlenirken pnömotoraks gelişen ve müdahale edilen bebeklerle, pnömotoraks gelişmeyen solunumsal sorunları olan bebeklerin epidemiyolojik özellikler, risk faktörleri, klinik seyir ve prognostik faktörler yönünden karşılaştırılması amaçlanmıştır. Gereç ve Yöntem: Bu retrospektif, kesitsel çalışmaya Ocak 2020-Mart 2021 tarihleri arasında çeşitli solunumsal sorunlar nedeniyle erken neonatal dönemde yenidoğan yoğun bakım ünitesine yatışı yapılan 246 hastadan 32’si dahil edildi. Olgular çeşitli solunumsal sorunları nedeniyle izlenirken pnömotoraks tanısı alan ve müdahale edilen hastalar (pnömotoraks grubu) (n=14) ve pnömotoraks gelişmeden solunum sorunları nedeniyle takibine devam edilen hastalar (kontrol grubu) (n=18) olmak üzere iki gruba ayrıldı. Hasta bilgileri geriye dönük hasta dosyalarından ve hastane veri tabanından taranarak kaydedildi. Bulgular: Gruplar demografik özellikleri bakımından karşılaştırıldığında iki grup arasında istatistiksel anlamlı farklılık saptanmadı (p>0,05). Klinik ve radyolojik bulgular kıyaslandığında gerek non-invaziv, gerekse de invaziv mekanik ventilasyon tedavi süresinin, antibiyotik tedavi süresinin, total parenteral beslenme süresinin ve total oral beslenmeye geçiş süresinin pnömotoraks grubunda daha uzun olduğu görüldü (p<0,05). Pnömotoraks grubunun klinik ve radyolojik bulguları incelendiğinde pnömotoraks tanısının ortalama 27,3 saat içerisinde konulduğu, hava kaçağının çoğunlukla sol hemitoraksta gerçekleştiği (%64,3), yenidoğanların %78,6’sında eşlik eden ek hava kaçağı bulgusunun veya toraks tüpüne bağlı komplikasyonun olmadığı, kapalı su altı drenaj süresinin ortalama 4,1 gün olduğu görüldü. Sonuç: Bu çalışmada neonatal dönemde pnömotoraksın sıklıkla sezaryenle doğan bebeklerde, en sık erkeklerde ve sol hemitoraksta olduğu gösterilirken, pnömotoraks gelişen bebeklerin izlem ve tedavi süreçlerinin pnömotoraks gelişmeyen bebeklere göre farklılıkları ortaya konmuş ve klinisyenlerin bu özellikler açısından farkındalıklarının seyir ve prognozu etkileyebileceğine dikkat çekilmek istenmiştir
