Article Citation Count: 4Extending peer-led team learning to management education: The effects on achievement, critical thinking, and interest(Elsevier Sci Ltd, 2022) Şahin, Neriman Gonca Güzel; Çiğdemoğlu, Ceyhan; Cigdemoglu, Ceyhan; Tuzlukaya, Şule; Tourism Management; Public Relations and Advertising; BusinessAs an attempt to extend the implementation of peer-led team learning to management education, this study proposes to investigate business students' achievement, critical thinking skills, and interest in learning environment across academic ability groups and attitudes towards team leaders. Using a one-shot pre/post experimental design, 108 conveniently selected students participated in the treatment throughout ten weeks. Researchers collected data using the critical thinking scale and interest scales both at the beginning and at the end of the treatment. In addition, students' course achievement is used as a dependent variable. To answer research questions, paired-samples t-test, one-way repeated measure analysis of variance (ANOVA), and multivariate analysis of variance (MANOVA) were used. Results indicate that the mean scores of achievement are significantly different for different ability group students and different levels of attitudes towards team leaders. Besides, students' interest scores increased at the end of the implementation; however, their scores on critical thinking skills decreased. Further studies are suggested to consider these issues in implementing peer-led team learning in social science courses.Article Citation Count: 0New Organizations in Complex Networks: Survival and Success(Sciendo, 2022) Tuzlukaya, Şule; Senyuva, Zuhal; Tuzlukaya, Sule; BusinessPurpose: The present study investigates the survival and success of new organizations in the light of complex network theory. Methodology: The empirical data was collected using the survey method from the technology park companies are analyzed with social network analysis. Two main methods were used in this study: descriptive statistics and social network analysis. Findings: The findings indicate that new nodes appearing because of splitting up of bigger nodes from present or other related networks have a higher degree of centrality. In practice, this means that companies founded by former members of large-scale companies from these networks are more successful due to the ease in providing the flow of resources and information through previous links. This suggests that the imprint effect can be observed in the appearance, lifecycle, and performance of new nodes in complex networks. Originality: The literature lacks studies on new organizations' lifecycle in complex networks despite the existence of studies about new organizations in organizational networks. This study examines the appearance, success, and survival of new organizations in networks by complex network approaches such as dynamism, dissipative structures, and uncertainties.Article Citation Count: 3Testing Health Expenditure Convergence in 21 OECD Countries by Using Nonlinear Unit Root Tests(Duzce Univ, Fac Medicine, 2022) Omay, Tolga; Omay, Tolga; Çelik, Eşref Uğur; Tuzlukaya, Şule; Economics; BusinessObjective: The purpose of this study is to analyze the stochastic time series behaviour of health expenditure in the 21 OECD countries between 1975 and 2019 using a variety of state-of-the-art (cutting-edge) unit root tests. Methods: In this study, the linear ADF unit root test and eight relevant nonlinear unit root tests are used to empirically estimate whether the 21 OECD countries' health expenditure data show convergence. Results: The empirical findings are in support the stationarity of health expenditure in 20 of the 21 OECD countries. Conclusions: Health convergence hypothesis is confirmed in most OECD countries, indicating that health expenditure shocks have solely temporary effects on country-level health expenditure. The empirical study provides significant policy implications. The empirical part of the study indicated that policy measures chosen by the policymakers cannot be made without considering possible nonlinearities in health expenditure data. More investment in the policy proposals stated in the conclusion section in the low regime years, as well as the continuation of current ones in the high regime periods, have been determined to offer appropriate conditions for health spending convergence. Furthermore, it has been determined that structural changes outside of the regime have resulted in a change in health expenditure convergence in countries such as Japan and South Korea. It is essential to invest in these countries while taking into account the periods of structural change.
