The Total Quality Management (TQM) system is known to have a beneficial impact on sustainability. This study aimed to elucidate the achievement of hospital sustainability by analyzing the relationship between the implementation of TQM practices (leadership of management, decision making, continuous improvement, customer focus, employee involvement, process management, and relations with suppliers), and their impact on the financial and operational performance of hospitals. The gathered data underwent analysis using structural equation modeling (SEM) to empirically investigate the impact of TQM methods on the financial and operational performance of hospitals. A total of 1069 surveys were completed in 6 privately-owned and 26 publicly-owned hospitals located in the Marmara region of Turkey. This study contributes significantly by addressing gaps in the existing literature. There is a lack of empirical research that has examined the potential correlation between TQM, operational success, and financial performance in both public and private hospitals. Especially in developing nations like Turkey, the focus is on the early phases of implementing TQM principles, with a primary emphasis on continuous improvement and sustainable performance. The results demonstrate that Total Quality Management (TQM) exerts a substantial impact on the financial and operational performance of hospitals in the service industry.

As energy is vital in the sustainability of almost every part of daily life, energy security has become more crucial than ever before. One of the main threats to energy security is a possible disruption along the trade network, which jeopardizes the constant energy supply. The purpose of this research is to identify the relation ties between EU countries in order to clarify the characteristics of the network, such as its crucial actors, vulnerabilities, structural holes, etc., to help achieve some proposals for a more sustainable and secure energy supply. This will help identify the underlying causes of recurring energy crises in the EU and provide insight into developing management strategies for further studies. Following this purpose, we examined the trade network density to clarify typical characteristics of the network, applied degree centrality measures to identify the most central importer and exporter countries, and found the dominance and critical vulnerabilities of actors in the network by using domestic import data of the EU countries. Finally, we recommend some policies and management strategies according to the obtained results and previous literature for further discussion.

The main aim of this study is to examine the effects of Total Quality Management (TQM) practices (leadership of management, decision making, continuous improvement, customer focus, employee involvement, process management and relations with suppliers) on the financial and operational performance of hospitals in service industry. The data of the study were collected by the questionnaire prepared in the light of published studies and the suggestions of medical and administrative staff. Medical and administrative staff were chosen as target participants that reflect perspectives of hospitals. 1069 questionnaires were answered in 6 private and 26 public hospitals in the Marmara region in Turkey. The results claim that “customer focus” affects both operational performance as well as the financial performance of hospitals more than other TQM practices. While “process management” and “customer focus” explain the variance of financial performance significantly. “Process management” does not explain variance of operational performance.

For the research, data were collected from technology-oriented production companies operating in Istanbul. The reason for choosing these companies is that global capabilities become even more important in the world of technology in terms of innovation and production performance. In this context, it is aimed to examine the effects of both global capabilities and learning orientation in the constantly changing technology world. A sample of 1044 participants was taken to set up and test the model and analyzes were performed using SmartPLS 3.3.5. In the research, it can be explained by supporting the hypotheses that both innovation and production performances are positively affected if technology-oriented production companies have global capabilities and can realize the learning orientation.

For the research, data were collected from senior managers working in jointly established export-oriented ventures. The reason for choosing these initiatives is to examine whether partnership capabilities and entrepreneurial orientations' effects on export performance and innovation performance are successful in ventures established with export-oriented partnerships. Since the research is conducted in organizational areas where export-oriented enterprises are concentrated, it is an innovative study, and at the same time, the sample group of the research consists of ventures established in partnership. Data were collected from 601 senior employees for modeling and testing, and the lists registered with technoparks, entrepreneur associations, and entrepreneur foundations in Istanbul/Turkey were used. SmartPLS 3.3.5 was used for analysis. As a result of the data analysis in the research, it can be explained that both partnership abilities and entrepreneurial orientations positively affect export and innovation performances. These results show how important talents are in export-oriented ventures established in partnership. When the limitations of the research are evaluated, it will not be correct to generalize the research results since the data obtained from the enterprises registered to technoparks, entrepreneur associations, and entrepreneurial foundations operating in Istanbul represent a specific region. For this reason, it is recommended that the results obtained in this study should be evaluated only according to the sample group, and this situation should be taken into account in future studies.

Covid-19 pandemisi başta sağlık olmak üzere birçok alanda krize neden olan ekonomik ve sosyal bir krizdir. Çalışmamızda Covid-19pandemisi sırasında rekabet stratejileri ile pazar performansı arasındaki ilişkide girişimcilik odaklılığın aracılık rolü incelenmektedir. ISO 500 listesinde yer alan 137 firmadan toplanan anketlerle yapılan çalışmanın analizleri SPSS 20.0 istatistik programı ile analiz edilmiştir. Çalışmanın sonuçlarına bakıldığında işletmelerin maliyet liderliği ve farklılaşma stratejileri ile pazar performansı arasındaki ilişki kanıtlanmıştır. Rekabet stratejileri ile pazar performansı arasındaki ilişkide girişimcilik odaklılığın aracılık rolü incelenmiş, farklılaşma stratejisi ile pazar performansı arasındaki ilişkide girişimcilik odaklılığın kısmi etkisi kanıtlanmış ancak maliyet liderliği ile pazar performansı arasındaki ilişkide girişimcilik odaklılığın herhangi bir etkisinin olmadığı ortaya konmuştur. Çalışma bulguları, işletmelerin yürüttüğü rekabet stratejilerinin Covid-19pandemi dönemindeki belirsizlik ortamında pazar performansını nasıl etkilediği ve bu ortamda girişimcilik odaklılığın rolü konusunda alana katkı sunmaktadır.
