The purpose of this study is to measure and analyze the national innovation efficiency of organisation for economic co-operation and development (OECD) countries. This is to determine to what extent OECD countries efficiently use the elements that enable innovation activities possible in generating innovation outputs.

An input–output model was constructed to measure efficiency. The inputs and outputs in the research model are the input and output sub-indices of the Global Innovation Index. Data envelopment analysis was used to measure the national innovation efficiency levels of OECD countries.

The results show that national innovation efficiency is generally high in OECD countries. However, some countries lag behind in innovation efficiency. OECD countries’ ability to create and provide the elements that enable innovation activities is higher than their ability to create innovation outputs. OECD countries have a good innovation environment and a high level of resources, but they should focus on how to create more innovation outputs.

This study presents a measurement of national innovation efficiency of OECD countries which contributes “Innovation Strategy” agenda. The results empirically show that overall innovation indices cannot be the only indicator of the performance of national innovation systems. In this study, an innovation efficiency/performance matrix is constructed to present the relative positions of the countries to help in examining countries’ strengths, weaknesses and potentials based on innovation efficiency and innovation performance simultaneously. This study contributes to the literature by presenting a broader perspective and measurement of national innovation efficiency by taking an extensive number of indicators into account.

The purpose of this paper is to analyze the impact of logistics performance on the carbon (CO2) emissions of Balkan countries.

Fixed-effects panel regression analysis is used to estimate the causal relationship between CO2 emissions and logistic performances of Balkan countries. Logistics performance is measured by logistics performance index (LPI) which was published by the World Bank in 2007, 2010, 2012, 2014 and 2016 and used for ranking countries by means of their logistics performance. LPI is based on six main indicators: customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. As a measure of carbon emissions of sampled countries, the natural logarithm of carbon dioxide emission per capita is used in this study.

The results obtained reveal that there is a positive and significant relationship between logistics performance and CO2 performances of the sampled Balkan countries.

This study is based on only 11 Balkan countries. In this sense, the data used in the analysis is limited.

Considering the important geostrategic position of the Balkan region, logistics sector has an important role for the development of the countries in that region. In this sense, the findings of this study may provide useful insights for policymakers to achieve sustainable economic development. Furthermore, as far as the authors know, this is the first study that focuses on the relationship between logistics performance and carbon emissions of Balkan countries.

The complex geometries of human tissues are characterized by the employment of phantoms in various fields of medicine ranging from active treatment stages to educational purposes. Despite the exceptional abilities of the fused filament fabrication (FFF) technology to produce rapid and patient-specific complex anatomical models, the issue of human tissue-filament material incompatibilities persists owing to the lack of attenuation coefficients in the same range as biological tissues. The purpose of this study is to develop a novel biodegradable filament that can mimic human hard tissues by addressing the challenge mentioned above.

The current study addresses the issue through proposing a novel biodegradable radiopaque filament containing poly (lactic acid) (PLA) and antimony trioxide (Sb₂O₃) with increasing amounts (3 wt%, 5 wt% and 10 wt%) for hard tissues. Other than the thermal/flow characterization and internal structural analyses, as for evaluating the effectiveness of the produced filament under computed tomography (CT) imaging, two detailed anthropomorphic phantoms (L3 vertebra and femur bone) are produced and tested.

Results show that Sb₂O₃ disperse homogeneously and serve as a nucleating agent for PLA crystallization. Gyroid pattern gets very close isotropic structure with the highest hounsfield unit (HU) values. 5 wt% Sb₂O₃ is required to get the HU values of cortical bone. The produced model hard tissues are in very compatible with patient images in all details including cortical thickness.

The results of this study will contribute to the development of radiopaque products in medical applications using three-dimensional printing.

The current research shows that inexpensive, patient-specific, detailed medical models can be produced with a novel biodegradable radiopaque filament containing PLA/Sb₂O₃. To the best of the authors’ knowledge, no study has examined the use of Sb₂O₃ in radiopacity applications in any polymeric material.

This research aims to determine the contribution of publications in the context of Türkiye to the international entrepreneurship literature between 2005 and 2022. We examined 471 articles published in international journals in the Web of Science (WoS) Core Collection database using bibliometric analysis techniques. We analyzed the data with the software Biblioshiny+Bibliometrix, SciMAT, and VOSViewer. We used performance, theme and evolution, co-authorship, and document analysis in data analysis. Performance analysis findings show that the most publications were made in 2021, the journal with the most publications was sustainability, and the author with the most publications was Bakır, C. Theme and evolution analysis revealed that the motor themes were corporate entrepreneurship, gender and entrepreneurial intentions in the first period (2005–2014), while institutional entrepreneurship stood out as the niche theme. In the second period (2015–2022), “corporate entrepreneurship” and “performance” emerged as the motor themes, while the niche themes in this period were “Syrian refugees” and “entrepreneurial intentions.” Document analysis findings show that the most studied entrepreneurship types are gender, family, corporate, social, and small business, respectively. In addition, immigrant/refugee entrepreneurship is emerging as a new topic, while indigenous entrepreneurship, informal entrepreneurship, sustainable entrepreneurship, and religion entrepreneurship are the most minor studied topics in entrepreneurship. Evidence-based decision-making inputs were obtained for those holding the resource allocation authority in Türkiye. Policymakers and funders, as well as individuals and institutions that want to design the future in terms of resources, can benefit from the findings and analysis of this chapter. Türkiye, which ranks 26th in the world regarding entrepreneurship, must develop a policy based on data.

The purpose of this research is to provide a critical review of the intellectual capital (IC) research in hospitality and tourism (HT) literature.

This study uses 141 research papers published on IC in HT between 2003 and 2021 to offer the findings of a systematic review of publications that cover the issue of IC as a holistic concept, rather than just a component of it, within the sector.

The progress on the topic is addressed. The authors' findings also reveal the related research productivity, main themes compared to other service sectors and methodologies applied in the knowledge field. In order to provide a tangible structure in the field, a research agenda is offered.

This study analyzed the development of IC research in the HT literature by focusing on journal articles in the Scopus database. The findings could aid researchers in (re)designing their study goals so they may add to both general IC literature and literature related to HT.

A strong positive relationship between IC and HT organizations’ performance has been demonstrated, but no study has previously mapped the research constituents of publications in IC research. To contribute to the endeavor of knowledge consolidation on this subject, the authors' paper covers the research that has been done so far on the under-researched issue of IC in HT from a new perspective.

The purpose of this paper is to experimentally and numerically investigate the cooling performance of the air-to-water thermoelectric cooling system under different working conditions.

An air-to-water thermoelectric cooling system was designed and manufactured according to the principle of discrete binary thermoelectric Peltier modules, and the thermal performance, heat transfer rate and average COP values were examined at different cooling water temperatures and voltages applied. Additionally, numerical simulations were performed by computational fluid dynamics approach to investigate the temperature distribution and airflow structure inside the cooling chamber.

Analyses were performed using experimental tests and numerical methods. It was concluded that, by decreasing the cooling water temperature from 20 to 5 °C, the average COP increases about 36%. The voltage analysis showed that the efficiency of the system does not always increase as the voltage rises; more importantly, the optimum voltage is different and depends on whether it is desired to increase COP or increase the cooling rate.

In the studies published in the field of thermoelectric cooling systems, little attention has been paid to the voltage applied and its relationship to other operating conditions. In most cases, the tests are performed at a constant voltage. In this study, several options, including applied voltage and cooling water temperature, were considered simultaneously and their effects on performance have been tested. It was found that under such studies, optimization work should be done to evaluate maximum performance in different working conditions.

The present study aims to provide a practical and robust assessment technique for assessing countries' investability in global supply chains to practitioners. Thus, the proposed approach can help decision-makers evaluate and select appropriate countries in the expansion process of the global supply chains and reduce risks concerning country (market) selection.

The present study proposes a novel decision-making approach, namely the REF-Sort technique. The proposed approach has many valuable contributions to the literature. First, it has an efficient basic algorithm and can be applied to solve highly complicated decision-making problems without requiring advanced mathematical knowledge. Besides, some characteristics differentiate REF-Sort apart from other techniques. REF-Sort employs the value or value range that reflects the most typical characteristic of the relevant class in assignment processes. The reference values in REF-Sort and center profiles are similar in this regard. On the other hand, class references can be defined as ranges in REF-Sort. Secondary values, called successors, can also be employed to assign a value to the appropriate class. REF-Sort can also determine the reference and successor values/ranges independently of the decision matrix. In addition, the proposed model is a maximally stable and consistent decision-making tool, as it is resistant to the rank reversal problem.

The current papers' findings indicate that countries have different features concerning investment. Hence, the current paper pointed out that only 22% of the 95 countries are investable, whereas 19% are risky. Thus, decision-makers should make detailed evaluations using robust, powerful, and practical decision-making tools to make more reasonable and logical decisions concerning country selection.

The current paper proposes a novel decision-making approach to evaluate. According to the authors' information, the proposed model has been applied to evaluate investable countries for the global supply chains for the first time.

In this study, the author aimed to measure the effect of customer loyalty on customer citizenship behavior as well as the effect of experience value perceptions of tourist railway journey customers on customer loyalty within the scope of social exchange theory.

The author obtained data from 126 participants who had experienced the tourist railway adventure through random sampling. In the next stage, the author extracted the data obtained with the bootstrapping sample technique to 5,000 samples. The author analyzed these obtained data with the PLS-SEM model with the Smart PLS 3 software.

The results of the research show that the most important experience value dimension that creates loyalty in the touristic railway journey is the emotional value dimension; the second important dimension is the hedonic value dimension and other experience value dimensions did not have any effect on customer loyalty intention levels. In addition, an important result of the study is that loyal customers mostly intend to advise other customers, and relatively less of them intend to give feedback to the firm.

The fact that the concepts of touristic railway journeys are different due to the nature of tourism is an important limitation of the study, which is only for individuals who have experienced the Touristic Eastern Express. The fact that the Touristic Eastern Express is a long journey and stops at many destinations on its arrival and departure route can affect customers' perceptions of the experience value.

The values that create customer loyalty in the touristic railway journey are mostly emotional and hedonic values. In addition, customers who are loyal as a result of this journey are more intent on advising other customers than giving feedback to the firm.

The study was carried out on the customers of the touristic eastern express, which started its activities in 2019. Ensuring customer loyalty for the sustainability of this trend has significant tourism potential; Afterwards, the transformation of customer loyalty into customer citizenship has a very important place. In addition, as far as we have examined the literature, the absence of similar studies in the tourism sector is an indicator of the study's originality. Considering these data, it is expected that the study will fill an important gap in terms of both sectoral and academic.

The purpose of this paper is to investigate the preschool teachers’ cultural intelligence, their attitudes towards multicultural education and the correlation between these two variables.

The sample consisted of 203 preschool teachers working in preschool classes within primary schools administrated by the Ministry of Education in Turkish Republic of Northern Cyprus (TRNC). Data were collected from the teachers by cultural intelligence scale (CQS), teacher multicultural attitude survey (TMAS) and demographic information form.

The analysis revealed that cultural intelligence and attitudes towards multicultural education did not differ according to teaching experience in a foreign country. Significant differences were found in metacognition, motivation and behaviour sub-dimension scores, cultural intelligence total scores and multicultural education attitude scores because of having a friend in foreign country, cognition sub-dimension scores because of having a non-Turkish-speaking student (NTSS) in class and cultural intelligence total scores because of knowing a foreign language. Significant relation was found between cultural intelligence scores and multicultural education attitude scores of the participants.

Despite the increasing cultural diversity in the country, there are no official regulations or efforts to establish arrangements for multicultural education in TRNC. Thus, this research is valuable for clarifying the situation in TRNC, determining the requirements and providing insights for future scientific work and implications.
