This paper aims to investigate the internationalization motives behind location choice among emerging country business groups (EBGs) and the way in which institutional factors affect Türkiye’s foreign direct investment (FDI).

This study develops a multi-perspective framework that integrates the ownership, location and internalization (OLI) paradigm (Dunning and Lundan, 2008) and the linkage, leverage and learning (LLL) model (Mathews, 2006) with neo-institutional theory to explain the internationalization of EBGs. It adopts a multiple-case study research method relying on 14 semi-structured interviews with top executives to explore the internationalization strategy of a set of Turkish BGs.

This study supports the combination of the OLI paradigm, the LLL model and neo-institutional theory to explain EBGs’ internationalizing behaviors. Turkish BGs have adopted both asset exploitation and asset augmentation internationalization strategies. The institutional legitimacy mechanism moderates the internationalization motives of Turkish BGs, and their host country location choice and normative pressures are more salient than their regulative and cognitive pressures.

This study is based on a sample of EBGs from Türkiye, and this restriction limits the generalizability/applicability of the findings to BGs globally.

Few studies have considered EBGs and their internationalization strategies in the international business field. This paper puts forward an integrated framework for analyzing internationalization and legitimacy in the institutional context of EBGs. This study highlights that BGs bridge institutional voids. Focusing on Turkish BGs helps to answer Granovetter’s Coasian question and contributes to the understanding of emerging countries’ economic development.

The purpose of this study is to evaluate different strands of institutional theory within the internationalization process of multinational enterprises (MNEs) in developed and emerging economies. In the light of this purpose, the authors try to fill the gap in the literature through analysing the main institutional theories: neo-institutionalism, new institutional economics, comparative capitalism and the institution-based view. Therefore, the main concern is to determine the distribution of different strands of institutional theory in its subfields in this study.

This study provides a profound analysis of different strands of institutional theory within the period from 1990 to 2018 in a larger sample. With a qualitative content analysis, authors reviewed 150 articles using different strands of institutional theory at both theoretical and analytical level and accessed 25 journals published in Social Science Citations Index between 1990 and 2018. In this study, authors used the inductive approach and the qualitative content analysis (Duriau et al., 2007) and adopted a research method to investigate different strands of institutional theory within the internationalization process of MNEs in developed and emerging markets (EMs).

Coders have synthesized the strands of institutional theory in detail to analyse the theoretical contribution of the study. The strands of institutional theory have been analysed both by institutional perspective and citation analysis. Coders classify the analysis level into three main categories. These are country, headquarter and subsidiary level. Our findings are related to the basic determinants and assumptions of different strands of institutional theory. Because in new institutional economics, analysis levels are country and industry. On the other hand in institution-based view, analysis levels are country and firm. Finally in comparative capitalism, analysis levels are country and region and, in neo-institutionalism analysis level is organization itself. In this study, findings show that sociology-based institutional strands, especially neo-institutionalism, are more preferred than other theories.

This study’s content analysis is limited to scope of selected journals. However, this study may suffer from publication bias. The authors examined only peer-reviewed articles from selected journals and did not include book chapters, book reviews, editor and special issue editor articles, research notes, conference papers and congress invitations. The important theoretical limitation of this study is to clarify the different strands of institutional theory in international business literature (Aguilera and Grøgaard, 2019). The firm size of MNEs is not included in this study, but it should be involved in coding categories in future studies.

This study provides the largest sample up to now and covers developed markets and EMs. Authors analysed this research from four perspectives: theoretical foundation, methodology, location and entry mode choices. On the other hand, this study shows that the institutional environment not only mitigates or mediates the effects but also directs the effects on foreign direct investment’s internationalization process of location choice and entry strategies.

This paper aims to investigate the moderating effects of a board of directors on foreign direct investment (FDI)’s international diversification in Turkey.

A sample of Turkish multinational firms with FDI was used. Two different aspects of international diversification were considered: the relationship between international diversification and financial performance and the moderating effect of board composition on the relationship between international diversification and the firm’s financial performance. Firm-level data were obtained from the Istanbul Stock Exchange in Turkey.

The findings reveal that international diversification leads to better financial performance according to market-based measures. On the other hand, this study indicates that the board characteristics have a moderating effect on international diversification and financial performance.

The study is based on a sample of publicly listed firms in Turkey, and this restriction limits the generalizability of the findings.

The internalization efforts of Turkish FDI have led to better financial performance in terms of market-based measures. The results have stated that the interest of independent outside directors is aligned with lower-risk investment decisions. Independence of independent outside directors in Turkey is interrogated by practitioners or the Capital Markets Board of Turkey. The larger board size which a moderator variable is provided, the wider shareholder value in Turkey is.

One can understand that the development of market-supporting institutions provides the support for entry to an emerging economy which is inefficient or incomplete markets and highly concentrated family ownership.

These findings provide important implications for corporate governance and highlight the need for further research on the role of governance in firm internationalization. This study not only helps to understand how board characteristics affect the choice of international diversification decisions, but the results also allow to assess the performance implications of these choices for a particular period.

The aim of this study is to develop a knowledge scale for nutrients of tropical and traditional fruits for university students and conduct its validity and reliability. Another purpose of the study is to determine whether or not the students' knowledge mean scores about nutrients of tropical and traditional fruits vary based on their demographic information.

The design of the study was the survey model. While the population consisted of 1,551 students studying in the faculty of health sciences, Gazi University, the sample consisted of 668 students who were determined based on criterion sampling.

When examining in terms of gender of the students, it was determined that even though mean score of the knowledge scale for nutritional values of tropical and traditional fruits was slightly higher in female students (X¯ = 8.12) than male students (X¯ = 7.71), there was an insignificant difference between them (t₍₆₆₆₎ = 1.25, p > 0.05). A significant difference was determined between the students' knowledge mean scores of the knowledge scale for nutritional values of tropical and traditional fruits in terms of residence place (t₍₆₆₆₎ = 2.86, p < 0.5). While the nutritional value mean score of the students residing in Ankara was low (X¯ = 7.67), the nutritional value mean score of the students residing out of Ankara was high (X¯ = 8.58).

When the scale developed in this study is analysed according to demographic information, it can be asserted that the students had knowledge about the nutrients of tropical and traditional fruits. Although tropical fruits are expensive, they still prefer these fruits. It can be stated that the students had knowledge about the diversity, nutritional compounds and antioxidant content of tropical and traditional fruits.

The purpose of this paper is to investigate the heat transfer rates from the kerf surfaces and skin friction at the kerf wall due to the jet impingement in relation to laser cutting process.

Three‐dimensional modeling for the flow and heat transfer analysis is considered. The numerical scheme using the control volume approach is introduced to solve the governing equations of flow and heat transfer. The k‐w turbulence model is incorporated to account for the turbulence.

It is found that the Nusselt number and the skin friction remains high in the region next to the kerf inlet and it decreases towards the kerf exit for all kerf thicknesses considered. The flow acceleration in the kerf also results in the second peak of the Nusselt number and the skin friction.

The melting at the kerf surface was omitted and the constant temperature boundary representing the melt surface is incorporated in the analysis. However, care was taken during the mesh generation to avoid grid dependent solutions.

The findings and discussions provide the useful information on the practical laser cutting process, in particular, physical insight into the effect of the kerf thickness on the heat transfer and skin friction.

No previous work has been carried out in three‐dimensional space to predict the heat transfer and skin friction, which are important for practical laser cutting applications. Therefore, the work reported is original.

Recently, online learning and online environments have become even more important. Students' engagement, fear of missing out and Internet addiction are seen as interrelated components that affect students' online teaching and learning process. In this context, university students' engagement, fear of missing out and Internet addiction in online environments, the relationship among them and students' demographic characteristics, online environment usage status and Internet usage profiles as their predictors are examined in this study.

This is a relational study and is carried out with 179 university students. Personal information form, student's engagement, fear of missing out and Internet addiction scales were used as data collection tools. Descriptive statistics, t-test, one-way ANOVA, correlation, hierarchical linear multiple regression analysis are used for the analysis.

According to the results, variables related to students' demographic characteristics, online environment usage status and Internet usage profiles together significantly predict the students' engagement, fear of missing out and Internet addiction in online environments. When students think positively about taking courses online, their engagement increases accordingly and their fear of missing out levels decrease. Increase in student's academic achievement leads to decline in Internet addiction.

In practice, examining the related variables about students in terms of engagement to the learning environment, fear of missing out and Internet addiction could bring a new perspective to studies on problematic use of the Internet and technology such as nomophobia and digital distraction. The results of this study reveal how and which components to be focused on for increasing the university students' engagement, reducing Internet addiction and fear of missing out in online learning environments.

The findings of this study provide a versatile perspective with the variables of student participation, fear of missing out, Internet addiction and their predictors in online learning environments, which are becoming widespread and increasingly important today and shed light on future researches.

The purpose of this paper was to evaluate the quality characteristics of white button mushroom powder enrichment in sponge cake. The developed product can be a promising inclusion in the convenience functional foods and would serve the purpose of improving nutritional status of consumers.

Cakes containing graded levels of agaricus bisporus (white button mushroom) powder were prepared by replacing wheat flour with 10, 20, 30, 40 and 50 per cent mushroom powder. The effect of mushroom powder supplementation on physical, nutritive and sensory quality of the cakes was evaluated and analyzed statistically using Agres-Agdata software.

Batter density and specific volume of cake samples decreased with increasing levels of mushroom powder in the formulation, which is contrary to the knowledge that they are inversely proportional. For 20 per cent enrichment, batter density and specific volume decreased by 8.23 and 5.79 per cent, respectively. There was no significant difference in individual organoleptic attributes of cake samples up to a level of 20 per cent fortification of mushroom powder, with significant nutrient enrichment (p > 0.05).

Replacing flour in cakes has been tried with many protein-rich ingredients to improve the nutritional quality of cake although with limiting success when it comes to sensorial acceptability. Mushroom powder was incorporated in the formulation to enrich sponge cakes. The processing technology will also reduce post-harvest losses in mushrooms and improve the nutritional status of society.

The purpose of this paper is to study Al-based green composite. To make composite samples of aluminium alloy (AA3105) with different weight percentages of rice husk ash (RHA) and eggshell (ES) particles as reinforcement, stir casting method was used.

Several other aspects, including the weight percent of reinforcing agent particles, the applied stress and the sliding speed, were taken into consideration. During the course of the wear test, the sliding distance that was recorded varied from a minimum of 1,000 m all the way up to a maximum of 3,135 m (10, 15, 20, 25 and 30 min). The typical range for normal loads is 8–24 N, and their speed is 1.58 m/s.

With the AA/ES/RHA composite, the wear rates decreases when the grain size of the reinforcing particles enhanced. Scanning electron microscopy images of worn surfaces show that at low speeds, delaminating and ploughing are the main causes of wear. At high speeds, ploughing is major cause of wear. Composites with better wear-resistant properties can be used in wide range of tribological applications, especially in the automotive industry. It was found that hardness increases at the same time as the weight of the reinforcement increases. Tensile and hardness were maximized at 10% reinforcement mix in Al3105.

In this work, ES and RHA has been used to develop green metal matrix composite to support green revolution as promoted/suggested by United Nations thus reducing the environmental pollution.

The main objective of this research is to investigate the factors that influence consumer purchase decisions for halal products before and during the COVID-19 pandemic, based on the Engel-Kollat-Blackwell (EKB) theory.

The research was conducted as a survey. The influencing factors were determined based on the grey relational analysis (GRA) approach.

The findings indicate before the COVID-19 pandemic, consumers mainly purchased halal products based on four key factors: purchasing experience, certification label, Internet searches and past consumption experience. However, during the pandemic, the ranking and factors have changed to six indicators, which are past consumption experience, purchasing experience, certification labels, standardized specifications, Internet searches and halal certification labels.

The study was limited by the sample size and geographical area. Nevertheless, the findings could be further explored by expanding related theories toward understand human decisions based on spiritual beliefs.

The findings of this study have important implications for research, practice and society. Understanding the factors influencing halal purchase decisions before and during the pandemic can help businesses, policymakers and halal certification bodies to better cater to consumers' needs and preferences and ensure the continued growth and development of the halal industry.

This study evaluates halal purchasing decisions between periods of certainty and uncertainty by using the GRA. Changes in halal consumption and purchase decisions in response to COVID-19 pandemic have become an emerging topic of discovery. The study addresses the gap in the literature regarding changes in consumer decision pattern.
