Does governance affect corporate diversification behaviour in emerging markets?
(Routledge Journals, Taylor & Francıs Ltd, 2020) Sener, Pınar; Akben Selçuk, Elif
This paper investigates the role of firm-level and country-level governance on corporate diversification behaviour in emerging markets. The results show that firms with combined leadership structure are more diversified while firms with more independent directors are less diversified. There is a U-shaped relationship between ownership concentration and diversification. No significant association between country-level shareholder protection and diversification is demonstrated.

Judgments of Capability and Conformity as Distinct Forms of Social Judgments, and the Way They Interact To Shape Evaluator Decisions
(Wiley, 2020) Topaler, Başak; Küp, Eyuep Tolunay
Objective Social judgments are evaluators' opinions about the social properties of a set of actors. Different types of judgments rendered by the evaluators and potential interactions between them may have major consequences for the actors who are evaluated. In this article, we distinguish between judgments of capability and conformity, and examine their concurrent and interdependent effects on evaluator impressions. Methods We investigate these dynamics in the context of authors competing for the best paper award at the Academy of Management (AoM) conference. Results Findings of our empirical analyses demonstrate interdependent effects of capability and conformity judgments on the committee members' decisions. We demonstrate that evaluators expect greater conformity to their ideal template from more capable actors who have greater potential to contribute to these ideals. Conclusion Our study advances the literature on social judgments by showing that congruence (or incongruence) among distinct types of judgment shape evaluators' decisions, beyond their independent effects.

Municipal Solid Waste Management Via Mathematical Modeling: a Case Study in İstanbul, Turkey
(Elsevier, 2019) Çavdaroğlu Ayvaz, Nur; Çoban, Aslı; Fırtına Ertis, İrem
The prominence of managing municipal solid waste (MSW) in an efficient and effective manner is increasing from day to day. In this paper, the solid waste management (SWM) system of İstanbul is analyzed by applying the techniques from mathematical programming methodology. In this manner, the solutions of the two optimization problems which aim to minimize the total cost and the environmental effects of SWM, respectively, are presented in this study. Additionally, a sensitivity analysis is performed and a multi-objective problem that combines two problems is presented. In this regard, the application of five MSW management technologies which are currently in use in İstanbul on six waste components is analyzed; and the optimal solution regarding the best mixture of these technologies is developed on a given waste composition. Besides, this optimal solution is compared with the current practice in İstanbul; and recommendations are presented about possible future investments for the policymakers. The results of the study emphasize the importance of material recovery and incineration facilities to improve profitability and to minimize environmental side effects. In particular, material recovery facility (MRF) should be expanded to be able to treat all of metal, paper and plastic from a cost management perspective. Incineration (INC) facility should also be expanded in order to treat plastics or organic waste from a Greenhouse Gas (GHG) minimization perspective. In addition to this, landfill appears to be the most prominent treatment technique according to the current problem parameters. However, regarding the waste composition, the amount of organic waste must be decreased by more than 37% for other waste streams to be treated in different facilities other than landfill. Anaerobic digestion and composting facilities need to be more cost-effective for becoming economically feasible. The methodology represented in this study can be extended and generalized to other cities around the world once the correct problem parameters are specified.

Responses To Replica (vs. Genuine) Touristic Experiences
(Pergamon-Elsevier Science, 2020) Gülen, Sarial-Abi; Ezgi, Merdin-Uygur; Gürhan-Canlı, Zeynep
A growing trend in tourism is the use of replica experiences. Yet, consumers' responses to replica (vs. genuine) touristic experiences are mostly overlooked in the literature. In this paper, we propose that consumers' perceptions of authenticity of the replica (vs. genuine) touristic experiences mediate their responses to these experiences. We define three theoretically driven factors that influence the authenticity perceptions of consumers-experience characteristics (restricted experience vs. not restricted experience; within close vs. distant geographical proximity to the genuine) and a consumer characteristic (salient goal: collecting experiences vs. having fun/pleasure), which influence consumers' responses to replica and genuine touristic experiences. We found support for the proposed theory using two field studies from Egypt's Luxor Tutankhamun tomb and three experimental studies.

Role Conflict Role Ambiguity and Proactive Behaviors: Does Flexible Role Orientation Moderate the Mediating Impact of Engagement?
(Routledge Journals Taylor & Francis Ltd, 2019) Maden-Eyiusta, Ceyda
This study investigates the relationships between role conflict role ambiguity and proactive behaviors at work (i.e. individual innovation and taking charge) as mediated by work engagement. It also investigates the moderating role of flexible role orientation on the relationships between role conflict and ambiguity work engagement and employee proactivity. Data were collected from 227 employees and their supervisors working in 20 small and medium-sized enterprises in Istanbul Turkey. The findings indicated that role conflict was negatively related to taking charge while role ambiguity was negatively related to individual innovation. Work engagement acted as a full mediator in the relationship between role ambiguity and individual innovation while partially mediating the relationship between role conflict and taking charge. With regard to the moderating role of flexible role orientation the findings indicated that the conditional indirect relationship between (a) role conflict and taking charge and (b) role ambiguity and individual innovation through engagement were stronger when the level of flexible role orientation was low.
