Traditional Folklore Forms in Temasa-I Dunya Ve Cefakar U Cefakes
(Milli Folklor Dergisi, 2016) Şişmanoğlu Şimşek, Şehnaz
Temasa-i Dunya ve Cefakar u Cefakes written by Evangelinos Misailidis in 1871-1872 has widely been considered to be an adaptation of the Greek novel O Polipathis (1839) and its originality has not been adequately emphasized in past studies. This article suggests that Temasa-i Dunya should be considered an original novel since it incorporates traditional folklore forms peculiar to Ottoman literature which are absent in Polipathis. This study first of all describes the variety and the origins of the traditional folklore forms in Temasa-i Dunya and delineates the literary tools by the help of which they were included in the text. Furthermore it analyzes how these elements affect the narrative discourse and the author's purposes in employing them. The analysis demonstrates that in Temasa-i Dunya oral and print culture materials of both Muslim and non-Muslim origins are embedded in the text primarily in the form of narrative digressions and digressions from the frame story. These digressions carry the marks of the traditional story teller both in terms of functionality and at the discursive level. In other words Misailidis' narrator being an active subject similar to the story teller in the oral culture chooses and manipulates the appropriate traditional story in accordance with the messages he conveys to the Karamanli readership. It can also be said that unrealistic features of traditional stories are eliminated and the stories are presented in a realistic style and content. Moreover the aforementioned narratives help to overcome the limited perspective of the first person narrative and to portray a variety of experiences. Temasa-i Dunya also presents a folkloric panorama of 19th century Istanbul through numerous idioms and proverbs.

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.

Determinants of Corporate Cash Holdings: Firm Level Evidence From Emerging Markets
(Springer, 2017) Akben Selçuk, Elif; Altiok-Yilmaz, Ayse
The objective of this chapter is to investigate the factors affecting corporate cash holdings in five emerging markets namely Brazil Indonesia Mexico Russia and Turkey. The sample consists of 1991 firms listed on the major stock exchange of their countries and covers the period between 2009 and 2015. The model is estimated by Arellano–Bond dynamic generalized method of moments. Results show that firms which use higher leverage in their capital structure hold more cash. More profitable firms are shown to have higher levels of cash holdings. Another variable which has a positive effect on the level of cash holdings in any given period is the level of cash holdings in the previous period as shown by the positive and significant coefficient of the lagged dependent variable in the model. Liquidity and firm size have a negative and statistically significant impact on the level of corporate cash holdings. Firms with higher level of capital expenditures are also shown to hold less cash. Finally growth opportunities do not have a significant impact on the level of cash holdings for the firms in the emerging markets analyzed. © Springer International Publishing AG 2017.

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.

Service Employee Burnout and Engagement: the Moderating Role of Power Distance Orientation
(Springer, 2016) Auh, Seigyoung; Mengüç, Bülent; Spyropoulou, Stavroula; Wang, Fatima
Studies show that service employees are among the most disengaged in the workforce. To better understand service employees' job engagement this study broadens the scope of the job demands-resources (JD-R) model to include power distance orientation (PDO). The inclusion of PDO enriches the JD-R model by providing a key piece of information that has been missing in prior JD-R models: employees' perceptions of the source of job demands (i.e. supervisors) or employees' views of power and hierarchy within the organization. Study 1 uses a survey-based field study to show that employees with a high (compared to low) PDO feel more burnout due to supervisors when they are closely monitored by their supervisors. Study 1 further supports the finding that employees with high (compared to low) PDO feel less disengagement despite burnout due to supervisors. Study 2 using a lab experiment and Study 3 relying on a survey-based field study unveil why these effects were observed. Stress and job satisfaction emerge as mediators that explain the findings from Study 1. Implications of the role of PDO are discussed to improve the current understanding of how job engagement can improve customer service performance.

Customer Participation Variation and Its Impact on Customer Service Performance: Underlying Process and Boundary Condition
(Sage Publications, 2020) Mengüç, Bülent; Auh, Seigyoung; Wang, Fatima
Drawing on the customer participation (CP) literature, this research proposes that CP variation is the degree to which employees perceive variability across customers with regard to customers sharing information, time, and effort and making suggestions to enhance the service delivery process and outcome. Drawing on the job demands-resources model, this research explicates the mediating process by which CP variation affects customer service performance and its boundary conditions. Study 1 uses data from a field study in the banking industry to show that CP variation negatively influences customer service performance through greater customer-related burnout. The authors show that this mediation process is moderated by contingencies that mitigate or exacerbate the indirect relationship. Study 2 further validates the CP variation construct by testing for discriminant validity against similar and related constructs, such as CP quality, in more diverse service industries (insurance, legal consulting, travel and tourism, health care, and physical fitness). Finally, an examination of the moderating role of CP quality provides a more nuanced picture of the intricacies between CP variation and CP quality. This article concludes with a discussion of the theoretical and practical implications for CP variation research.

Empirical Evidence of Revenue Management in the Cruise Line Industry
(Sage Publications Inc, 2019) Ayvaz Çavdaroğlu, Nur; Gauri, Dinesh K.; Webster, Scott
Revenue management (RM) has received considerable attention from both academic and business professionals. It encompasses several techniques regarding capacity allocation pricing and resource management of fixed time-sensitive capacity. RM can be roughly divided into two categories defined by the control mechanism that increases revenue: capacity allocation or price optimization. Our work falls in the latter category. In our model we allow for partial substitutability among products (e.g. a customer making a purchase decision may consider multiple alternatives-different departure dates different destinations different cabin types). We also include marketing expense in addition to prices as a lever for increasing revenue. These features are relevant to dynamic pricing in practice. The method is illustrated with booking data from a cruise company yielding optimal advertising and prices for 300 products. The application of the model results in an increase in revenue in the range of 8%-20%.
The “karakoncolos/kalikancaros” belief in Turkish and Greek sources [Türkçe ve yunanca kaynaklarda karakoncolos/kalikancaros inancı]
(Milli Folklor Dergisi, 2018) Şişmanoğlu Şimşek, Şehnaz
The belief in “karakoncolos/kalikancaros” is seen in a wide geography spreading from Central Anatolia and Black Sea region in Turkey to Balkan Peninsula including Greece Bulgaria and Serbia. Though karakoncolos is defined under different names in Turkish sources the period it is depicted and its features are almost similar. According to this the karakoncolos believed to have emerged on the coldest days of the year is depicted as a creature that is often hairy resembling animal haunting people and disturbing them. One of the first written sources in Turkish that included the belief in karakoncolos is Evliya Çelebi’s Seyahatnâme. Today it is rarely a tradition in games such as “karakoncilo” in the Eastern Black Sea or a belief that has been almost forgotten or even unknown by the majority even though it continues to exist as a trivial image in Turkish literature and cinema. On the other hand this belief often referred to as kalikancaros in Greek was compiled by the folklorist Nikolaos Politis at an early date (1904). In this study first of all referring to the various beliefs concerning kalikancaros in the mentioned compilations of Politis the rewritings of them in the present Greek children’s literature by Filippos Mandilaras will be introduced. In today’s Greece it will be revealed that especially during the Christmas period it continues to exist as a popular figure of the musical performances in schools and in children’s books. When we have a look at the Turkish and Greek compilations of this belief in general which is spread over a wide geographical area we can see that the reviewed Turkish sources are mostly collected from the Eastern Black Sea region and rarely lived as an almost forgotten tradition. Today in Greece also due to the Velloudios’ paintings which still circulate today the mentioned belief continues to exist as a “national” and a popular element of the childrens’ literature. © 2019 Milli Folklor Dergisi.

Unpacking the Relationship Between Materialism Status Consumption and Attitude To Debt the Role of Islamic Religiosity
(Emerald Group Publishing Limited, 2016) Yeniaras, Volkan
Purpose - The purpose of the study is to investigate how religiosity affects these relationships inTurkey where consumption is de-stigmatized among a new economic elite with strong ties to Islamism. The literature commonly associates religion and ideology with anti-capitalism and anti-consumption. Although consumer researchers have studied both topics examination of whether materialistic values translate into status consumption and whether religiosity has an effect on the relationship between status consumption and consumer attitude to debt remains scant. Design/methodology/approach - This paper investigates the relationship of materialism to status consumption and the mediating role of Islamic religiosity on the relationship between status consumption and attitude to debt. Structural equations modeling was used on a judgmental sample of 267. Findings - The results showed that the materialistic values positively affect status consumption for the Islamists. This paper concludes that Islamic religiosity not only does not reject consumption but also augments the relationship between status consumption and consumer attitude to debt. Originality/value - The findings have shown that previous studies that identify Islam as a threat to consumerism have overseen the class struggles and the role of status consumption. This paper successfully provided empirical evidence that the religiosity not only does not reject consuming but intensifies the relationship between status consumption and attitude to debt for those with Islamist dispositions.

A New Energy Paradigm for Turkey: A Political Risk-Inclusive Cost Analysis for Sustainable Energy
(Elsevier Science, 2011) Oksay, Serhan; İşeri, Emre
Implementing sustainable development policies in order to achieve economic and social development while maintaining adequate environmental protection to minimize the damage inflicted by the constantly increasing world population must be a major priority in the 21st century. While the emerging global debate on potential cost-effective responses has produced potential solutions such as cap and trade systems and/or carbon taxes as part of evolving sustainable energy/environmental policies this kind of intellectual inquiry does not seem to be an issue among Turkish policy-making elites. This is mainly due to their miscalculation that pursuing sustainable energy policies is much more expensive in comparison to the utilization of fossil fuels such as natural gas. Nevertheless the pegged prices of an energy sector dominated by natural gas are illusive as both the political risks and environmental damage have not been incorporated into the current cost calculations. This paper evaluates energy policies through a lens of risk management and takes an alternative approach to calculating energy costs by factoring in political risks. This formulation reveals that the cost of traditional fossil-based energy is in fact more expensive than renewable energy. In addition to being environmentally friendly the paradigm shift towards renewable energy policies would provide Turkey with a significant opportunity to stimulate its economy by being one of the first countries to develop green technologies and as a result this burgeoning sector would prompt job creation as well ; mainly due to the externalities.

Efficiency Analysis of Emergency Departments in Metropolitan Areas
(Elsevier, 2020) Akkan, Can; Karadayı, Melis Almula; Ekinci, Yeliz; Ulengin, Füsun; Uray, Nimet; Karaosmanoğlu, Elif
The demand in the healthcare industry is increasing exponentially due to aging population of the world and this is leading to a rapid increase in the cost of healthcare. The emergency departments of the hospitals are the frontline of health care systems and play an additional critical role in providing an efficient and high-quality response for patients. The overcrowding at the emergency departments due to growing demand results in a situation where the demand for ED services exceeds the ability to provide care in a reasonable amount of time. This has led countries to reconsider their health policies in a way to increase their efficiency in their healthcare systems in general and in emergency departments, in particular. As in many countries, there has been a steady and significant increase in the number of patients that seek health services at the emergency departments of state hospitals of Turkey, due to the significant structural reforms in health services since 2003. While meeting this increasing demand, it is ever more important to provide these critical health services efficiently. Therefore, the efficiency of the emergency departments of seven general hospitals run by Istanbul's Beyoglu State Hospitals Association have been analyzed using categorical Data Envelopment Analysis (DEA) models. The analysis of DEA results is supported by a set of statistical methods to make it easier for the hospital administrators to interpret the analysis and draw conclusions. The analysis shows that less-equipped EDs are supported by better equipped, larger EDs, resulting in a hub-and-spoke type of structure among the EDs where "satellite" EDs serve an important referral function and thus evaluating their efficiency without taking the interoperability among these units into account would not be an accurate assessment of their performance.

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.
Brand Love and Brand Forgiveness: an Empirical Study in Turkey
(Warsaw: Faculty of Management Publishing House. University of Warsaw, 2022) Tosun, Petek; Yanar Gürce, Merve; Öncü Eroğlu Pektaş, Güzide
Brand love is an interesting and important concept that required further research in brand management. This study tested the impacts of consumer attitudes, subjective norms, and brand anthropomorphization on brand love and brand forgiveness in the framework provided by the theory of planned behavior. Regression analyses showed that brand anthropomorphization and subjective norms have a signifi cant impact on brand love. Brand love positively infl uences brand forgiveness and acts as a mediator between subjective norms, brand anthropomorphization, and brand forgiveness constructs. Besides mediation, brand anthropomorphization directly infl uences brand forgiveness. The fi ndings of this study contribute to the existing knowledge on brand love and brand forgiveness concepts by presenting empirical research fi ndings that investigate brand love antecedents. This study has also shown the signifi cant impact of anthropomorphizing a brand on brand forgiveness and brand love.

Strategic Positioning and Quality Determinants in Banking Service
(2011) Akdag, Hatice Camgöz; Zineldin, Mosad
Purpose - The aim of this paper is to investigate and define the competitive positioning of banks including state-owned domestic and foreign banks operating in Istanbul Turkey. The aim is to check the competitive marketplace and to identify the major quality attributes which bankers themselves and their customers used in determining the overall perception of a given bank and services offered. Design/methodology/approach - The investigation was held in Istanbul Turkey. In total 30 banks were included in the research which includes state-owned local and foreign-owned banks. A total of 1530 questionnaires were submitted answers collected and analyzed. Reliability test and frequency analysis were used to analyze the data. Findings - From the banks' customers' point of view determinants relating to functional quality or how the customers wish to receive banking services became evident. It also became clear that customers of banks are not fully receiving what they want or need and their expectations especially on the most important attributes of quality are not being met. Research limitations/implications - The survey showed how the banks were selected and including their employees in relation to the other competitors' banks in the Turkish banking industry. Originality/value - The paper demonstrates an integrated technology use of staff talent and streamlined operations that respond to customer needs and encourage customers to use the whole range of banking products/services rather than only a few as the end game. The results were used by bank staff later on to reengineer and redesign creatively their positioning strategy and the future direction for creating more effective quality strategies. © 2011 Emerald Group Publishing Limited.

Corporate Governance and Tunneling: Empirical Evidence From Turkey
(Economics Bulletin, 2018) Akben Selçuk, Elif; Sener, Pınar
This study investigates whether internal governance mechanisms affect tunneling through intercorporate loans for a sample of Turkish listed non-financial firms over the period 2006 to 2014. While the findings reveal a significant and positive relationship between state ownership and tunneling and a significant and negative relationship between foreign ownership and tunneling the relationship between family ownership and tunneling is non-linear. In addition while board size is negatively associated with tunneling independent directors do not prevent the embezzlement of resources. Furthermore the results indicate that while older firms firms with family chairman and higher growth opportunities are more likely to engage in tunneling activities firm size high cash holding leverage and financial distress do not affect tunneling.

Frontline Employee Feedback-Seeking Behavior: How Is It Formed and When Does It Matter?
(Sage Publications Inc, 2019) Auh, Seigyoung; Mengüç, Bülent; İmer, Havva Pınar; Uslu, Aypar
This research comprises two studies that extend the literature on the proactive behavior of feedback seeking. Study 1 uses cross-sectional data from frontline employees across 51 apparel stores to examine how feedback seeking is formed and under what conditions. The results suggest that the development of feedback-seeking behavior is contingent on a feedback-seeking climate and the relationship between an employee and his or her supervisor. Study 2 uses longitudinal data collected across three time periods from multiple respondents (i.e. frontline employees and managers) not only to replicate the findings from Study 1 but also to explore when feedback seeking matters. The findings reveal that managers should target employees who are less (vs. more) satisfied with their jobs because such employees perceive more instrumental value from feedback as a means to improve customer service and sales performance. The findings from this research provide insights that managers can use to increase feedback-seeking behavior from employees and effectively identify and manage the conditions under which feedback seeking will occur to greater or lesser degrees.
Markaların Sosyal Medya Yardım Masası Hesaplarına Yapılan Şikayetlerin Analizi: Yüksek Teknoloji Ürünleri Üzerine Bir Çalışma
(Melih Topaloğlu, 2018) Önden, Abdullah; Kiygi Calli, Meltem
Bu araştırmada marka müşterilerinin satın alıp kullandıkları ürünlerle ilgili istek ve şikayetlerini ilettikleri çevrimiçi yardım masalarıyla olan etkileşimi incelenerek markaların şikayetlere nasıl yanıt verdikleri ve uyguladıkları şikayet yönetiminin müşterilerin duygularındaki değişimi nasıl etkilediği araştırılmış ve sosyal medya ağlarından elde edilen veriler duygu analizi yöntemiyle analiz edilmiştir. Çalışmada müşterilerin istek ve şikayetlerini ilettikleri paylaşımlarındaki tutumlarının duygusal değerinin ne olduğu, çevrimiçi yardım masasının konuyu nasıl ele aldığı ve çevrimiçi yardım masası ile olan etkileşimin uzunluğunun (soru ve cevap iletişiminin sayısı) tutum ve duygusal değeri nasıl etkilediği incelenmiştir. Araştırmanın sonuçlarına göre çalışmada ele alınan markaların kendilerine çevrimiçi yardım masaları üzerinden iletilen talep ve şikayetleri ivedilikle çözdükleri belirlenmiştir. Büyük markalar hizmet telafisi paradoksu teorisine göre hareket edip ürünleri hakkında sorun yaşamış ve ürün hakkında şikayette bulunmuş müşterilerini mutlu etmektelerdir. Böylece bu müşterilerin sadık müşterilere dönüştükleri sonucuna varılmaktadır.
