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.

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.

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.

When Does (mis)fit in Customer Orientation Matter for Frontline Employees' Job Satisfaction and Performance?
(Amer Marketing Assoc, 2016) Mengüç, Bülent; Auh, Seigyoung; Katsikeas, Constantine S.; Jung, Yeon Sung
The role of coworkers' customer orientation (CO) in influencing an employee's CO has received sparse attention in the literature. This research serves two purposes. First the study draws on person-group fit theory to develop and test a model of a frontline employee's CO relative to that of his or her coworkers as well as the effects of CO (mis)fit on job satisfaction and service performance through coworker relationship quality. Second the authors propose three workgroup characteristics-group size service climate strength and leader. member exchange differentiation-that they expect to mitigate the (negative) positive effect of employee. coworker CO (mis) fit on coworker relationship quality. Data collected in a multirespondent (i.e. frontline employees and supervisors) longitudinal research design indicate that as group size increases service climate becomes stronger and group leaders develop different exchange relationships with employees the inherently (negative) positive role of employee-coworker CO (mis) fit in influencing coworker relationship quality diminishes. Furthermore coworker relationship quality fully mediates the associations of employee-coworker CO (mis) fit with job satisfaction and service performance. The authors close with a discussion of the theoretical and practical implications of the boundary conditions of CO (mis)fit.

Family Involvement, Corporate Governance and Dividends in Turkey
(Emerald Group Publishing Limited, 2019) Sener, Pinar; Akben Selçuk, Elif
Purpose: The purpose of this paper is to investigate the relationship between dividends and family involvement as well as corporate governance characteristics among Turkish public firms. Design/methodology/approach: Using panel data on Turkish firms listed on the Borsa Istanbul 100 index for 2006–2014 three models are estimated. For the first two models where the dependent variables are the dividend payout ratio and dividend yield respectively tobit regressions are run. The last model which employs a dividend dummy as the dependent variable is estimated with logistic regression. Findings: There is a positive and concave relationship between family ownership and dividends. The existence of a family chairman reduces dividends. There is a positive association between board size and dividends and this relationship is weaker for firms with higher levels of family ownership. Finally the ratio of independent directors on the board is negatively associated with dividends. Practical implications: The findings imply that firms with substantial family ownership and active family participation in management are more likely to send a negative signal to minority shareholders by paying lower dividends. In addition minority shareholders should pay attention to the board structure of firms in which they invest. Originality/value: This study is one of the few to analyze the nonlinear relationship between family ownership and dividend payments as well as the role of family management in a developing country. Second it investigates the role of board characteristics in explaining dividend payment decisions. © 2019 Emerald Publishing Limited.

How Does Self-Concept Clarity Influence Happiness in Social Settings? the Role of Strangers Versus Friends
(Routledge Journals Taylor & Francis Ltd, 2019) Merdin-Uygur, Ezgi; Sarial-Abi, Gulen; Gurhan-Canli, Zeynep; Hesapci, Ozlem
Self-concept clarity (SCC) defined as the extent to which the content of an individual's self-beliefs is clearly and confidently defined and internally consistent influences experiences in social relationships. This paper extends the previous literature on SCC by proposing and demonstrating that high-SCC individuals anticipate and experience more happiness than low-SCC individuals when they share a social setting with friends and anticipate and experience less happiness than low-SCC individuals when they share a social setting with strangers and that this is because of perceived interpersonal distance. A series of four studies including both online studies and a field study support these predictions. Alternative explanations of self-esteem and self-efficacy are also ruled out. The findings yield both theoretical contributions and practical implications.

Babbling Through Social Media: a Cross-Country Study Mapping Out Social Networks Using Ewom Intentions
(Springer, 2023) Zülal, İşler; Kıygı-Çallı, Meltem; El Oraiby, Maryam
This research aims to determine the factors affecting the users’ electronic word-of-mouth (eWOM) seeking and sharing intentions and to reveal the interactions among and within clusters using social network analysis (SNA). This study includes three hierarchical sub-studies conducted in two countries, Turkey and Poland. First, we develop a segmentation for social networking site (SNS) users based on the frequency of sharing product-related information on SNSs. Second, we investigate the impact of several factors that affect eWOM seeking and sharing intentions using regression analysis. In the second sub-study, we also include the identified segments developed in the first sub-study as another factor that may have differentiated eWOM intentions. Third, to understand the degree of interaction among SNS users, we apply an SNA using the forecasted eWOM intentions scores from the second sub-study, which gives us hypothetical social networks. The results of SNA present strong interactions inter- and intra-clusters in both countries. Some key findings include the identification of three SNS user segments, including “Middlers,” that may be of particular interest to brands. We also find that in terms of eWOM intentions, users in Turkey are more active than in Poland. Although some predictors of eWOM seeking and sharing intentions differ between the two countries, users intend to be more active in eWOM seeking than in eWOM sharing. The comparative study provides valuable insights for decision-makers to engage different market segments via SNSs with various proposed features using suggested information contents for selected product categories.

Patterns of B2b E-Commerce Usage in Smes
(Emerald Group Publishing Limited, 2012) Sila, Ismail; Dobni, Dawn M.
Purpose - The purpose of this paper is to identify the B2B e-commerce (B2BEC) usage patterns of North American small- and medium-sized enterprises (SMEs) in their supply chains the contextual factors that influence usage patterns and the subsequent effects of these patterns on firm performance. Design/methodology/approach - The authors conducted an online survey of North American SMEs and obtained 229 responses. They utilized several statistical methods including cluster analysis and profile analysis to test five hypotheses. Findings - The TOE framework supplemented with interorganizational factors provides a valid theoretical guideline to study firms' B2BEC usage patterns. Three distinct types of B2BEC usage patterns - E-Limiteds E-Leaders and E-Laggards - emerged. Different sets of contextual factors contribute to the formation of these three patterns of B2BEC adoption. Higher levels of B2BEC usage result in stronger firm performance. Research limitations/implications - Future clustering variables could be more specific. The effects of other potential contextual factors should also be explored by future studies. This study can be replicated in other countries to determine whether the findings can be generalized. Practical implications - In light of the potential performance improvements that B2BEC adoption offers managers should assess the risks associated with maintaining their current speed of e-business deployment versus the risks associated with escalating it. Organizations that have been more reactive should consider how well or ill their sluggish approach prepares them for navigating the inevitability of increasing sophistication in supply chain management. Originality/value - Limited empirical research exists on theB2BECusage patterns of NorthAmerican SMEs the contextual factors that motivate them to adopt different B2BEC technologies in their supply chains and how each of these usage patterns affects their performance. The current study contributes to the literature by shedding light on these issues. © Emerald Group Publishing Limited.
Consumer Impulsive Buying Tendency Scale Development Using Mixed Methodology
(Beykoz Üniversitesi, 2018) Merdin-Uygur, Ezgi
In the domains of marketing and consumer behavior, there has been a paradigmatic shift from fully rational and mechanical human beings towards the dominance of feelings, irrationalities and impulses. Hence, there has been a growing demand for measurement tools capturing the multidimensional nature of buying processes. This study is an attempt to generate a reliable and valid scale to measure the impulsive buying tendency of customers. Impulse buying is of great importance with the technological developments and ease of purchasing. In this paper, the aim is to provide a comprehensive, valid and reliable impulse purchasing scale consisting of multiple dimensions. The steps included the analyses of existing scales, qualitative investigations (i.e. focus groups and critical incidences), a small scale pilot study for internal reliability and validity and a large scale quantitative study for scale purification and scale fit. A tridimensional impulsive buying tendency scale has been presented to the literature.

Cash Holdings and Corporate Governance: Evidence From Turkey
(IGI Global, 2019) Akben Selçuk, Elif; Şener, Pınar
This chapter investigates the empirical factors affecting corporate cash holdings with special emphasis on corporate governance variables for a sample of Turkish-listed nonfinancial firms over the period 2006 to 2010. The findings reveal a significant non-linear relation between family ownership and cash holdings. In addition, while board structure does not significantly affect the level of cash holdings, tunneling increases cash reserves of firms. Furthermore, the results indicate that cash flow, leverage, other liquid assets that can be used as cash substitutes, the degree of tangibility of assets, and firm size are important in determining cash holdings among Turkish companies.

Corporate Diversification and Firm Value: Evidence From Emerging Markets
(Emerald Group Publishing Limited, 2015) Akben Selçuk, Elif
Purpose - The purpose of this paper is to investigate the impact of corporate diversification on firm value in a sample of nine emerging markets including Brazil Chile Indonesia Malaysia Philippines Poland South Africa Thailand and Turkey. For the purpose of this study a company is classified as diversified when it is operating in two or more lines of business defined by the two-digit SIC codes. Design/methodology/approach - Employing panel data from 1568 companies for the period 2005-2010 this paper estimates both a fixed effects model and a dynamic generalized method of moments model. Data are collected both at company level and segment level within each firm. Findings - Overall analysis results suggest that for the period from 2005 to 2010 diversified firms in emerging markets are valued more compared to single-segment firms operating in similar industries providing support for diversification premium. Originality/value - The effect of diversification on company value in emerging markets is an important managerial and public policy concern. Although the literature on developed country diversified firms is rich only a few studies have examined diversification-value relationship in the context of developing countries. Furthermore most previous research on the value effects of corporate diversification in emerging markets has taken the form of case studies within countries and concentrated on the 1990s. This paper tries to fill these gaps by using a larger sample and more recent data and methodology.

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.

Using Fuzzy Set Theory in the Comparison of Customer Satisfaction Levels
(Süleyman Demirel Üniversitesi, 2019) Ayvaz Çavdaroğlu, Nur
Customer satisfaction is the key to the survival and profitability of all businesses. In the ever-changing business world, this concept has gained more importance. In particular, in industries where new firms based on new business models emerge, the traditional firms find it more difficult to compete with the new business models in terms of customer happiness. Sharing economy, which is defined as “renting non-frequently used resources (e.g. houses, cars, various commodities) in return of a certain price via digital platforms”, is one of these new concepts that have inspired new business models. A sharing economy-based company, Uber, has gained popularity in a short time. In this study, customer satisfaction levels of Uber and classical taxi firms are compared and the performance of each firm in various service dimensions is measured. Data is collected via questionnaires and analyzed using the fuzzy set theory models. According to the results, Uber performs much higher in all service dimensions with respect to the classical taxi firms. By evaluating the results from a managerial perspective, recommendations are developed for Uber and similar sharing economy-based firms, and the classical firms who want to compete with these new business models.

Municipal Solid Waste Management Via Multi-Criteria Decision Making Methods: a Case Study in Istanbul Turkey
(Elsevier Science, 2018) Çoban, Aslı; Ertiş, İrem Fırtına; Çavdaroğlu, Nur Ayvaz
In contemporary era solid waste management has become an important issue for developing countries. Rapidly increasing population higher life-standards and technological advancements consistently increase the amount and the diversity of solid waste. In such a complicated environment municipal authorities need to develop the most effective disposal solution to manage the ever-growing municipal solid waste. In this study various disposal techniques that are utilized globally are investigated and different scenarios that could be applicable to Turkey are created. These scenarios might also be implementable for other Europe and Central Asia (ECA) countries. For that purpose 8 solid waste disposal scenarios were evaluated via 7 criteria which are determined according to the opinions of the experts from the field. Towards this end three different multi-criteria decision-making methods namely Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) I and PROMETHEE II were utilized for the scenario evaluation. Consequently the most appropriate and feasible scenarios are determined. The results indicate the prominence of recycling and landfill technologies for developing countries. The results are consistent by means of all the three methodologies that are used. (C) 2018 Elsevier Ltd. All rights reserved.

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.
