Sustainability practices of family firms: the interplay between family ownership and long-term orientation

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO.     

Spillover effects on government bond yields in euro zone. Does full financial integration exist in European government bond markets?

This paper examines the time varying nature of European government bond market integration by employing multivariate GARCH models. We state that unlike other bond markets, in euro markets the default(credit) risk factor and other macroeconomic and fiscal indicators are not able to explain the sovereign bond yields after the beginning of monetary union. This fact might be counted as a signal for perfect financial integration. However, we also find that the global shocks affect Germany and the rest of euro bond markets in various levels, creating particular discrepancies in asset prices even we take into account the market specific factors. Different level responses of each euro market to the global shocks reveal that euro bond markets are not fully integrated with each other unlike the recent literature claimed. Besides, we explore that the global factors are effective for the volatility of yield differentials among euro government bonds.     

Misconceptions emerging in mathematics student teachers’ limit instruction and their reflections

The purpose of this study is to investigate the misconceptions emerging in mathematics student teachers’ limit instruction and the reflections of these misconceptions on their teaching. In this study, which used the case study design, regarding the limit concept, four senior mathematics student teachers’ four-hour limit instruction was examined within the context of misconceptions as described in the literature. Mathematics student teachers’ lesson plans, video recordings of the participants’ lessons in which they taught the concept of limit and audio recordings of semi-structured interviews were used to gather data. Participants carried their instruction mostly by demonstrating that the function’s limit is different than the function’s value at \(x=a\) . However, since mathematics student teachers did not have adequate knowledge of misconceptions regarding the limit concept, some misconceptions emerged in their teaching process. Three of the participants made illustrations by making use of the meaning attributed to limit in daily language, and this situation caused students to perceive the limit concept as the maximum value to be reached and as a boundary not to be exceeded.     

Is the US Dollar a Suitable Anchor for the Newly Proposed GCC Currency?

Responses of inflation and non‐oil output growth from the Gulf Cooperation Council (GCC) countries to monetary policy shocks from the United States (US) were estimated to determine whether there is evidence to support the US dollar as the anchor for the proposed unified currency. A structural vector autoregression identified with short‐run restrictions was employed for each country with Fed funds rate as the US monetary policy instrument, non‐oil output growth and inflation. The main results suggest that for inflation, the GCC countries show synchronised responses to monetary policy shocks from the US which are similar to inflation in the US, and for non‐oil output growth, there is no clear indication that US monetary policy can be as effective for the GCC countries as it is domestically. Consequently, importing US monetary policy via a dollar peg may guarantee only stable inflation for the GCC countries – not necessarily stable non‐oil output growth. If the non‐oil output response is made conscientiously – and there are concerns over the dollar’s ability to perform its role as a store of value – a basket peg with both the US dollar and the euro may be a sound alternative as confirmed by the variance decomposition analysis of our augmented SVAR with a proxy for the European short‐term interest rate.     

Fading attraction: Turkey's shifting relationship with the European Union

In this paper, we examine Turkey's changing economic relations with the European Union (EU) and the rest of the world during the past few decades. We argue that a combination of the EU's reluctance to accept Turkey as a member, internal economic and political developments, and the rise of economic and political opportunities elsewhere have shifted the country to diversify its economic relations around the world and reduced its reliance on the ties with Europe. This shift, which had started long before the 2008 global financial crisis and accelerated in its aftermath, seems to have helped Turkey weather relatively well the recent economic storms in Europe.     

On the feasibility of monetary union among Gulf Cooperation Council (GCC) countries: does the symmetry of shocks extend to the non-oil sector?

GCC countries’ output is heavily dichotomized into oil and non-oil. Oil shocks have similar effects on all member countries but little is known about their responses to non-oil shocks. This paper sets out to determine (1) whether aggregate demand (AD) and non-oil supply shocks (AS) are symmetrical across these countries to justify their suitability for monetary union; and (2) whether there is any commonality of shocks with the United States and the three major European countries, namely France, Germany, and Italy, which can warrant the choice of either the US dollar or the Euro as the anchor for the expected common currency of the bloc. We use bivariate structural vector autoregression models identified with long-run restrictions to extract the shocks. Our results show that (a) AD shocks are unequivocally symmetrical but non-oil AS shocks are weakly symmetrical across GCC countries thereby suggesting a monetary union is feasible, but not overwhelmingly; (b) neither AD nor AS shocks are symmetrical between GCC countries and the selected European countries; (c) GCC’s AD shocks are symmetrical with the US but non-oil AS shock are not. Furthermore, there are no significant changes in the results when we aggregate the GCC countries as a bloc. We therefore surmise that the US dollar is a more appropriate anchor for the new currency than the Euro since US monetary policy can at least help smooth demand shocks in GCC countries.     

The relationship between tourism,CO2 emissions and economic growth: a case of Mediterranean countries

This study explores the impact of tourism on economic growth considering CO₂ emissions utilizing panel data techniques for a sample of Mediterranean countries. The cointegration tests reveal that there is a positive long-run equilibrium between tourism, CO₂ emissions and economic growth. This positive long-run relationship may suggest that tourism increases the level of CO₂ emissions and has a statistically significant impact on economic growth in Mediterranean countries. Emirmahmutoglu and Kose (2011. Testing for Granger causality in heterogeneous mixed panels. Economic Modelling, 28(3), 870–876.) test results reveal that the tourism-led growth hypothesis, which suggests that tourism contributes to economic growth, is valid for Egypt, Italy, and Spain. Additionally, there exists a bidirectional relationship between tourism and economic growth both in Morocco and Turkey.     

Experiences of a dyslexic child in an English as a foreign language class

This qualitative study investigates and reveals the difficulties experienced by a dyslexic 7 year-old child learning English as a foreign language in a state elementary school. Aiming to advance the understanding of challenges dyslexics experience in English as a foreign language classes, a qualitative case study was designed. Thematic analysis of the interview data revealed that a dyslexic child struggles with linguistic difficulties, such as pronunciation, spelling, reading and writing. In addition, short and long term memory are impaired, which causes problems concerning word finding, memorization and naming objects. Contrary to the findings of most research, the participant of this study was found to be highly motivated towards learning English and that she had positive affectivity due to her personality. This study is expected to contribute to the teaching of English language to elementary school children with dyslexia and serve as a means to increase service quality of foreign language classes offered for dyslexic children.

     

Performance evaluation of reverse logistics in food supply chains in a circular economy using system dynamics

Supply chains are composed of multiple stakeholders who have complex interrelationships. In addition, the forward and reverse flow of materials, information, human resources, and finance occurs among different stakeholders in closing the loop of supply chains. Reverse logistics (RL) activities are gaining importance in terms of size and quantity due to both economic and environmental concerns. These flows in RL in supply chains are both dynamic and complex in nature. Further, the environmental impact of RL activities has barely been considered in holistic way in available literature. In this study, a system dynamics model has been developed to analyze and comprehend the green performance of RL activities by predicting the environmental impact of RL activities. The proposed model has been validated by a case study in the context of a food supply chain. In the company where the case study is carried out, the environmental effects of RL activities have been analyzed. These activities in a food supply chain in terms of CO₂ (carbon dioxide), NO_x (nitrogen oxide), SO₂ (sulfur dioxide), and PM (particulate matter) emissions have been predicted through a system dynamics model for the years 2020 to 2024. The proposed methodology is applied in a food supply context, a major player in retail business, especially in emerging economies. According to our findings, the RL activities in a food supply chain can significantly contribute to green performance management by minimizing food waste and loss; hence, the environmental impacts of such activities should be closely examined from a managerial perspective.
