Article Analysis of Publications on Health Information Management Using the Science Mapping Method: A Holistic Perspective(Healthcare, 2024-01-23) Tengilimoğlu, Dilaver; Orhan, Fatih; Şenel Tekin, Perihan; Younis, MustafaObjective: In the age of digital transformation, there is a need for a sustainable information management vision in health. Understanding the accumulation of health information management (HIM) knowledge from the past to the present and building a new vision to meet this need reveals the importance of understanding the available scientific knowledge. With this research, it is aimed to examine the scientific documents of the last 40 years of HIM literature with a holistic approach using science mapping techniques and to guide future research. Methods: This study used a bibliometric analysis method for science mapping. Co-citation and co-occurrence document analyses were performed on 630 academic publications selected from the Web of Science core collection (WoSCC) database using the keyword “Health Information Management” and inclusion criteria. The analyses were performed using the R-based software Bibliometrix (Version 4.0; K-Synth Srl), Python (Version 3.12.1; The Python Software Foundation), and Microsoft® Excel® 2016. Results: Co-occurrence analyses revealed the themes of personal health records, clinical coding and data quality, and health information management. The HIM theme consisted of five subthemes: “electronic records”, “medical informatics”, “e-health and telemedicine”, “health education and awareness”, and “health information systems (HISs)”. As a result of the co-citation analysis, the prominent themes were technology acceptance, standardized clinical coding, the success of HISs, types of electronic records, people with HIM, health informatics used by consumers, e-health, e-mobile health technologies, and countries’ frameworks and standards for HISs. Conclusions: This comprehensive bibliometric study shows that structured information can be helpful in understanding research trends in HIM. This study identified critical issues in HIM, identified meaningful themes, and explained the topic from a holistic perspective for all health system actors and stakeholders who want to work in the field of HIM.Article Capital structure decisions under uncertainty: the case of Turkey(Asia-Pacific Journal of Accounting & Economics, 2023-02) Dinçergök, Burcu; Eruygur, Hakkı OzanThis study analyzes the relationship between uncertainty and target leverage ratios on manufacturing firms listed in Borsa Istanbul between 2005–2020. To handle possible instrument proliferation and weak instrument problems of System GMM methodology of dynamic panel data, we mainly adopted the Quasi Maximum Likelihood estimator and found that uncertainty has a significant negative marginal effect on target leverage ratios. Our analysis revealed that firms with high levels of uncertainty have lower average leverage ratios than other firms. ANCOVA analysis results show that uncertainty is in the first three time-varying variables which have the highest impact on target leverage variation.Article Phase and wave dependent analysis of health expenditure efficiency: A sample of OECD evidence(Frontiers in Public Health, 2023-03-17) Boduroğlu, Elif; Atıcı, Kazım Barış; Omay, TolgaIntroduction: Health expenditures are a factor that reflects the government's public health policy and contributes to the protection of national health. Therefore, this study focuses on measuring the effectiveness of health expenditures in order to evaluate and improve the public health system and policy during the pandemic period. Method: In order to examine the effectiveness of health expenditures, the behaviors of the pandemic process were analyzed in two stages. The number of daily cases is analyzed in the first stage by dividing it into waves and phases according to the transmission coefficient (R). For this classification, the discrete cumulative Fourier function estimation is used. In the second stage, the unit root test method was used to estimate the stationarity of the number of cases in order to examine whether the countries made effective health expenditures according to waves and phases. The series being stationary indicates that the cases are predictable and that health expenditure is efficient. Data consists of daily cases from February 2020 to November 2021 for 5 OECD countries. Conclusion: The general results are shown that cases cannot be predicted, especially in the first stage of the pandemic. In the relaxation phase and at the beginning of the second wave, the countries that were seriously affected by the epidemic started to control the number of cas es by taking adequate measures, thus increasing the efficiency of their health systems. The common feature of all the countries we examined is that phase 1, which represents the beginning of the waves, is not stationary. After the waves fade, it can be concluded that the stationary number of health cases cannot be sustainable in preventing new waves' formation. It is seen that countries cannot make effective health expenditures for each wave and stage. According to these findings, the periods in which countries made effective health expenditures during the pandemic are shown. Discussion: The study aims to help countries make effective short- and long-term decisions about pandemics. The research provides a view of the effectiveness of health expenditures on the number of cases per day in 5 OECD countries during the COVID-19 Pandemic.Article The mediating role of FoMO and the moderating role of narcissism in the impact of social exclusion on compulsive buying: a cross-cultural study(Psychology: Research and Review, 2023-11-07) Mert, Merve; Tengilimoğlu, DilaverBackground There is an interrelationship between the concepts of social exclusion, compulsive buying behavior, fear of missing out (FoMO), and narcissism. Nevertheless, the extent to which these concepts mediate or moderate their relationships with each other has not been efficiently investigated. Objective This research aims to investigate how FoMO mediates and narcissism moderates the correlation between social exclusion and compulsive buying behavior. In addition, the research aims to test a conceptual model and highlight the differences that may occur in the conceptual model proposed in two different countries. Methods This model was analyzed among 1007 university students (Turkey = 506, Denmark = 501). The study used scales to measure social exclusion, compulsive buying behavior, FoMO, and narcissism. The study employed PROCESS Model 4 to analyze direct and indirect (mediation) effects and PROCESS Model 59 to assess conditional (moderation) effects. Furthermore, the Johnson-Neyman technique was utilized to investigate interaction terms. Results The findings indicate that those who face social exclusion tend to participate more in compulsive buying, and this connection is partly explained by FoMO. This suggests that individuals who encounter social exclusion may have an increased likelihood of experiencing FoMO, which may subsequently contribute to compulsive buying behavior. Furthermore, the moderating effect of narcissism differed between the Turkey and Danish samples. Specifically, in the Turkey sample, narcissism only modified the connection between social exclusion and FoMO, while in the Danish sample, it impacted both the connection between social exclusion and FoMO and the connection between FoMO and compulsive buying. Conclusion The obtained results show that the regulating role of narcissism is different in Turkey and Denmark within the conceptual model we studied.Article Evaluating the Financial Performances of the Publicly Held Healthcare Companies in Crisis Periods in Türkiye(Healthcare, 2023-09-20) Tengilimoğlu, Dilaver; Tümer, Tolga; Bennett, Russell L.; Younis, Mustafa Z.The purpose of this study was to evaluate the financial performances of the publicly held healthcare companies in crisis periods in Türkiye. The 2018 economic crisis and the COVID-19 pandemic crisis were included in the study as the crisis periods. We collected the financial data of the publicly held healthcare companies and calculated three liquidity, three turnover, three leverage and three profitability ratios through ratio analysis to use as financial performance indicators. We then conducted Wilcoxon signed-rank tests and we performed separate analyses for the 2018 economic crisis and the COVID-19 pandemic crisis. The results of the analyses showed that there were no statistically significant differences between the publicly held healthcare companies’ liquidity, turnover, leverage, profitability ratios and thus their financial performances before the crises and after the crises. While the results are reassuring and give valuable insights to managers and policy makers to determine the areas that needs to be strengthened to be better prepared for possible future crises, our sample was limited. Therefore, this study presents an exploratory foundation for future studies which are needed to make a case for financial stability for the publicly held healthcare companies before and after the crisis periods.Article Editorial: Economic growth and health expenditures relationship between OECD countries(Frontiers in Public Health, 2023-10-07) Tengilimoğlu, DilaverEditorial on the Research Topic: Economic growth and health expenditures relationship between OECD countriesArticle Industry 4.0 technologies, sustainable operations practices and their impacts on sustainable performance(Journal of Cleaner Production, 2023-02) Yavuz, Oğuzhan; Üner, M. Mithat; Karatepe, Osman M.; Okumuş, FevziUsing a natural resource-based view and technology-organization-environment framework as the theoretical focus, this paper develops and tests a research model in which sustainable operations practices mediate the impact of industry 4.0 technologies on sustainable performance. The model also tests sustainable operations practices as a moderator of the effect of industry 4.0 technologies on sustainable performance. Data obtained from 302 participants in Turkey’s technology development regions were utilized to gauge the aforesaid linkages via partial least squares structural equation modeling. As predicted, sustainable operations practices mediate the influence of industry 4.0 technologies on sustainable performance. Contrary to the study prediction, sustainable operations practices do not significantly moderate the impact of industry 4.0 technologies on sustainable performance. Theoretical and practical implications are discussed and future research directions are offered.Item İLAÇ SEKTÖRÜNDE MÜŞTERİ İLİŞKİLERİ YÖNETİMİ VE SATIŞ GÜCÜ NİTELİKLERİNİN FİRMA MARKA İMAJINA ETKİSİ(Bilim ve Teknoloji, 2014-12-12) ÖZGEN, PelinGünümüzde herşey değişiyor olsa da, işletmelerin hayatta kalabilmek için kâr etmek zorunda olmaları hala geçerliliğini koruyan bir olgudur.
