Abstract
Purpose
The volatility of exchange rate has generally been sighted as a primary cause for various shocks and instability in international trade of Ghana as witnessed over the years and most especially in recent times. Hence, owing to the increasing trade levels between Ghana and Ghana's global trading partners, the study aims to investigate if the trade–exchange rate volatility nexus in Ghana supports the positive, negative or ambiguous hypotheses?
Design/methodology/approach
The study investigates the effects of Ghana's exchange rate volatility on international trade by designing import and export equations to estimate both short- and long-run specifications of the effect and employing the multivariate generalized autoregressive conditional heteroskedasticity (GARCH) with Baba, Engle, Kraft and Kroner (BEKK) specification developed by Engle and Kroner (1995) as a further check for the robustness of the findings. Monthly data between 1993 and 2017 on the real effective exchange rates of Ghana's trade with 143 trading partners were taken as the series for modeling the volatility using GARCH andexponential generalized autoregressive conditional heteroskedastic (EGARCH) models.
Findings
The empirical results show that the volatility of exchange rate negatively impact export performances in the Ghanian economy. On the other hand, there was no sufficient evidence to support the observed positive effect of exchange rate volatility on imports, as the effects were only significant at 10% level in the long run. Thus, it is concluded that the finding cannot confirm a relationship between volatility and import. Thus, the results present differences in the direction of the effect of exchange rate volatility on imports and exports in the context of the Ghanaian economy.
Research limitations/implications
Considering the fragility of the Ghanaian economy and Ghana's macro-economic indicators, the study points at the crucial need for more integration of well-informed trade policies within the country's macro-economic policy framework to contain the impacts of exchange rate volatility on trade performances.
Practical implications
The study contributes to literature by scope and method. More specifically, empirical studies have failed or provided little evidence uniquely on the Ghanaian economy's reaction to exchange rate volatility on the country's imports and exports. Additionally, most of the existing empirical studies measure exchange rate volatility using the standard deviation of the moving averages of the logarithmic transformation of exchange rates. This method is criticized because the method is unsuccessful in capturing the effects of potential booms and bursts of the exchange rate. The authors' study circumvents for these highlighted pitfalls.
Social implications
The study contributes to literature by scope and method. More specifically, empirical studies have failed or provided little evidence uniquely on the Ghanaian economy's reaction to exchange rate volatility on the country's imports and exports. Thus, the study chat a course for socio-economic dynamic of Ghanaian economy.
Originality/value
The study contributes to literature by its scope and method, as extant empirical studies have provided little evidence specifically on the Ghanaian economy's reaction to exchange rate volatility. Additionally, most of the existing empirical studies measure exchange rate volatility using the standard deviation of the moving averages of the logarithmic transformation of exchange rates. This method is criticized because of the method's inadequacies in capturing the effects of potential booms and bursts of the exchange rate. The study thereby essentially circumvents for these highlighted pitfalls.

Abstract
This study explores the impact of virtual classrooms as an emerging classroom typology in comparison to the physical classrooms in the design process. Two case studies were held in order to infer design students' classroom preferences in the project lifecycle. The findings put forth figures that compare two forms of design communication in the two classroom types in terms of their contribution to design development. Although the students acknowledged many advantages of web-based communication in the virtual classroom, they indicated that they are unwilling to let go off face-to-face encounters with the instructors and fellow students in the physical classroom. It is asserted that the future design studio will be an integrated learning environment where both physical and virtual encounters will be presented to the student. Utilizing the positive aspects of both communication techniques, a hybrid setting for the design studio is introduced, comprising the physical classroom as well as the virtual one. The proposed use for the hybrid setting is grouped under 3 phases according to the stage of the design process; as the initial, development and final phases. Within this framework, it is inferred that the design studio of the future will be an integrated form of space, where the physical meets the virtual.

Abstract
Purpose
The purpose of this paper is to theorize and empirically investigate the formation of consumer’s consumption ritual experiences and discourses associated with Feast of Sacrifice.
Design/methodology/approach
The authors have approached the data from assemblage theory perspective. By use of ethnographic participant observation and in-depth interviews, seven themes are uncovered and discussed: meaning of Qurban, preparation of the ritual, Qurban choice, meat, Qurban ritual, marketplace and framing of discourses.
Findings
This study provides a theoretical development in which it depicts that assemblage theory can be used in the context of religious rituals such as the Feast of Sacrifice. This suggests that parts forming the social phenomena include different meanings and functions in different assemblages to the ritual, which has a structure with a particular process, roles and content scenario. This implies that even the most structured social phenomena as religious rituals can be accepted as social assemblage where every individual experiences his/her own ritual with the parts that have ever-changing material and expressive roles.
Originality/value
This study will contribute to the literature on religious rituals and practices through viewing ritual as an assemblage including material and expressive features as well as human and non-human actors. Besides, this study aims to find out whether there is a constant consumer and the concept of ritual by focusing on buying experiences of consumer in Feast of Sacrifice in Turkey.

Abstract
Purpose
The advent of social media brought a new perspective for guerrilla marketing since it allows ads to reach more people through the internet. The purpose of this paper is to investigate the influence of guerrilla marketing in social media on brand image.
Design/methodology/approach
A conceptual model was developed based on the information acceptance model (IACM). The research model was validated through structural equation modelling based on the surveys of 385 university students.
Findings
The results support the proposed model and confirm that guerrilla marketing in social media has a positive effect on both functional and symbolic brand image.
Research limitations/implications
This study was conducted with university students. This sample was deemed appropriate since the study had to be conducted with people who use social media. However, although the age group of university students constitutes the majority of social media users, they may not fully represent the whole population. Also, this study showed four guerrilla marketing examples to participants before they commenced filling in the questionnaire. Although the authors selected the most generic guerrilla advertisements during the pilot tests and eliminated the ones which were difficult to understand, this can still be considered as limitations of the study.
Practical implications
This study has both theoretical and managerial implications. First, most of the guerrilla marketing studies focus on consumers and neglect possible impacts on brands. In order to fulfil this gap in the literature, this study investigates the influence of guerrilla marketing in brand image. Besides, this study contributes to IACM by expanding its scope through testing its determinants on “brand image”. It proves that IACM is valid for use in different contexts. On the managerial side, this study provides marketers with a frame of reference to understand the information adoption process of guerrilla marketing on social media.
Originality/value
Current studies regarding the influence of guerrilla marketing mostly focus on consumers, where the possible impacts on brands have been relatively neglected. This study attempts to fill this gap by focussing on the brand image.

Abstract
Scientific research and delivering education at undergraduate and graduate levels are the main responsibilities of higher education institutions. Considering these points, we aimed to provide insights into an array of topics pertaining to scientific research and tertiary education in Turkey and the future of Turkish higher education. We focused on research-based education, lifelong learning, research and higher education institutions, research grants and funding in Turkey, performance management in higher education, international collaborations, future of hands-on approaches, and lastly the issue of brain drain in Turkey. In the endeavor to present these issues in detail, we employed sector analysis method. Throughout the chapter, we aimed to provide detailed and comparative evaluations making use of both national and international literature.

Abstract
Purpose
This study aims to analyze notable distribution dispute cases from Islamic law history. The authors will assess these alongside resolutions proposed by historical authorities, some of which evolved into established Islamic case law. In addition, the authors intend to apply classic fair division rules to these cases, providing alternative solutions. Using a game-theoretical approach, the authors plan to compare Islamic solutions with traditional division rules through axiomatic analysis. The goal of this study is to systematically explore the unique principles underpinning Islamic distributions.
Design/methodology/approach
In this study, the authors collate Islamic inheritance law disputes involving conflicting claims, unresolvable by primary Islamic law sources, from historical and modern texts. The authors formally model these as claims problems, surplus-sharing problems and adapted claims problems. Concurrently, the authors gather the proposed solutions and historical backgrounds offered by the era’s authorities and jurists. These solutions are axiomatically generalized into rules, while the axioms characterizing distribution rules are checked if they are aligned with Islamic norms and values. This approach facilitates a comparison between Islamic distributions and classic division rules.
Findings
The 'Awl and Radd doctrines, used in Islamic inheritance law, are axiomatically equivalent to the Proportional Rule, a prevalent non-Jewish division rule. These doctrines present solutions impervious to manipulation by legal heirs through rights transfer, unlike other possible distributions. Ibn 'Abbas' solution for Awliyya cases uses sequential priorities and diverges uniquely from classic fair division rules in the literature. In addition, it is established that Abu Yusuf's (b. 729) distribution for a legal dispute is axiomatically identical to Abraham ibn Ezra's (b. 1089) division rule.
Research limitations/implications
There is a noticeable dearth of comprehensive studies investigating contentious disputes concerning resource claims within Islamic law. Many of these studies are lacking in-depth analyses of diverse cases, casting doubts on their reliability. As a result, a robust focus is needed on case collection prior to any analytical process. Future research should concentrate on collating instances of fair division problems throughout Islamic history, as well as separately collecting methods of Islamic sharing. This procedure may lead to the characterization of various Islamic regulations, thereby emphasizing distinct Islamic principles. In forthcoming studies, conducting an exhaustive axiomatic evaluation of the cases and proposed resolutions is imperative.
Practical implications
This research illuminates existing knowledge gaps, setting a course for novel research trajectories. It underlines the fair division literature’s oversight of disputes within Islamic law, despite the plentiful existence of contentious cases. The research underscores the relevance of cooperative game theory as a tool for dissecting Islamic legal disputes. By accounting for unique Islamic norms and principles, this study lays a foundation for a nuanced comprehension of the dynamics and outcomes of legal disputes. By integrating an interdisciplinary approach, this research strives to bridge the gap between game theory and Islamic law.
Social implications
Beyond addressing a significant research lacuna, this study carries extensive societal implications. By shedding light on enduring debates within Islamic law, it encourages a rejuvenated understanding of the evolution and interpretation of legal disputes. The axiomatic disparities between rulers’ and jurists’ methods provide invaluable insights within the Islamic context, bolstering the understanding of sociocultural dynamics that influence legal decision-making. This research has the potential to shape legal discourse, guide policymaking and spur scholarly, juristic and societal dialogue. Consequently, it may foster a more comprehensive and enlightened approach toward the resolution of legal disputes in Islamic law.
Originality/value
To the best of the authors’ knowledge, this study is the first to examine Islamic law’s historical legal disputes from a game-theoretical standpoint. Existing studies rarely collect distribution disputes systematically, and none scrutinize the axiomatic rationales underlying authorities’ and jurists’ distributions, opting instead to focus on historical backgrounds. While the fair division literature extensively examines disputes, it often overlooks those originating from Islamic law, which presents a rich source of disputes that can be modeled as fair division problems. This research makes a distinct contribution by incorporating disputes from Islamic law into the existing body of cooperative game theory literature.

Abstract
Purpose
This paper aims to investigate the association of neighborhood location with place attachment and residential satisfaction.
Design/methodology/approach
First, the authors reviewed the literature on place attachment and residential satisfaction, and then generated a questionnaire based on the scales from the literature. The authors surveyed 135 respondents in two neighborhoods of Ankara, a metropolitan city in Turkey: one in the city center, the other in a suburb. To analyze the data, first, factor analysis, and later, multivariate analysis of variance and correlation tests were conducted.
Findings
The results indicated that place attachment and residential satisfaction were positively correlated, in congruence with the related literature; however, neighborhood location appeared to be associated only with residential satisfaction. The theoretical and practical implications of the results are discussed with respect to the recent issues on housing.
Originality/value
The effects of neighborhood location on place attachment and residential satisfaction (by comparing two different residential areas of the city) have not been adequately examined in earlier studies. The study results provide an understanding of the effectiveness of residential location on improving place attachment and residential satisfaction and contribute to the existing literature. Although the study findings may not be generalized to other locations in Turkey, this study contributed to the previous studies on place attachment and residential satisfaction by providing data from Turkish residents, which is less often examined.
