Alone but Together Autonomous but Related: Self-Construal Effects on Happiness in Social Experiences
(Wiley, 2018) Merdin-Uygur, Ezgi; Hesapci, Ozlem
Communal tables and open workspaces have become popular servicescapes that is contemporary spaces for experiencing dining or working alone but together. Previous research demonstrates that experiencing with close others (e.g. with friends or family) increases happiness and satisfaction but experiences shared with strangers in contexts such as communal tables or workshops have not yet been thoroughly analyzed. Addressing this research gap from a social-psychological perspective we suggest that even though individuals are generally happier when they share experiences with loved ones self-construal plays a moderating role in the relationship. Individuals with high autonomy and high relatedness do not anticipate greater happiness from experiences shared with friends than with those shared with strangers. Three experimental studies (two online and one field) demonstrate this effect using different operationalizations of autonomy relatedness. Managerial implications are discussed and suggestions are made for future research.

Antecedents and Performance Outcomes of Value-Based Selling in Sales Teams: a Multilevel, Systems Theory of Motivation Perspective
(Springer, 2020) Mullins, Ryan; Mengüç, Bülent; Panagopoulos, Nikolaos G.
Firms are increasingly deploying a value-based selling (VBS) approach in their sales organizations to drive growth for new offerings. However, VBS adoption remains challenging, signaling that leaders need guidance to motivate VBS. Drawing from the systems theory of motivation, we examine motivational mechanisms at two levels-salesperson and sales team-to understand how to motivate, and benefit from, VBS. Using multisource data (i.e., salespeople, managers, archival performance) from 70 sales teams in a U.S.-based manufacturing and services provider, our findings illustrate drivers and outcomes of VBS. Specifically, we uncover a framework of salesperson, leader, customer, and team factors that help explain salesperson motivation for VBS. Importantly, we link VBS to customers' adoption of new products to support VBS's role for selling new products. Critical for sales team strategy, our model also integrates a team-level motivational mechanism to provide a comprehensive framework for salesperson and sales team motivations and outcomes.

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.

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.

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.

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.

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%.

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.

(Emerald Group Publishing Limited, 2016) Camgöz-Akdağ, Hatice; İmer, Havva Pınar; Ergin, Kebire Nazlı
Purpose - The purpose of this paper is to employ quality function deployment (QFD) method for translating internal customer needs and expectations into appropriate service specifications to perform existing process assessments in relation to quality characteristics for increasing internal customer satisfaction. Design/methodology/approach - The integration of SERVQUAL into QFD has been used to set the success factors to improve quality in the textile industry. One of the largest textile companies in Turkey provided the sample. A SERVQUAL-type of questionnaire was used and a total of 32938 questionnaires were distributed both manually and online 24551 usable were received comprising a response rate of 77.31 percent. Findings - Findings of the QFD application suggest internal customer focus as having the highest weight score of almost 12 percent improvement. In addition improvements in technical requirements of politeness and process communication have a 9 percent impact each on internal customer satisfaction criteria. Research limitations/implications - QFD technique is able to provide companies with a better understanding of internal customer expectations and translate these into appropriate service specifications and perform existing process assessment. Originality/value - This paper is a first attempt that applies this integrative approach to a different type of industry thus offering practical and applied information for professionals engaged in academia and as practitioners.

An Investigation of Financial Literacy Money Ethics and Time Preferences Among College Students: a Structural Equation Model
(Emerald Group Publishing Limited, 2019) Aydin, Asli Elif; Akben Selçuk, Elif
Purpose: Financial literacy has a strong influence on financial well-being and it is a concept especially important for college students who start to develop their financial habits. The purpose of this paper is to examine the relationship between financial literacy money attitudes and time preferences among Turkish university students. Design/methodology/approach: Data were collected from 1443 university students from 14 campuses in Turkey. Structural equation modeling methodology is employed to test the hypotheses. Findings: The results suggest that students with higher financial knowledge scores have more favorable financial attitudes and exhibit more desirable financial behaviors. It is also demonstrated that financial attitude is positively related to financial behavior. Furthermore a significant and negative relationship between the affective dimension of the money ethic construct and financial behavior is found. In contrast the relationship between the behavioral dimension of money ethic and financial behavior is positive. It is further demonstrated that a present orientation leads to more negative financial attitudes. Originality/value: This study will reveal the interrelationships among dimensions of financial literacy money ethics and time preferences in an emerging economy with a relatively little experience with formal financial systems and unstable macroeconomic conditions. © 2019 Emerald Publishing Limited.

The Limitations of Turkey's New Foreign Policy Activism in the Caucasian Regional Security Complexity
(Routledge Journals Taylor & Francis Ltd, 2011) İşeri, Emre; Dilek, Oğuz
A panoramic outlook on the present global system shows that the US has been failing to preserve its global preponderance against the rise of new contenders from Asia. Turkey's new foreign policy demeanor under the AKP government reflects this shift of global power from the West to the East leaning on both of these two poles (especially Russia and the US) thereby aims at creating a 'zero-problem' situation with the neighboring Caucasian states. Yet this strategy has not achieved its goal mainly due to the ongoing debates not only between Moscow and Washington but also between Azerbaijan and Armenia in the Caucasian Regional Security Complexity. This work tries to read all these developments by applying insights from the neoclassical realist standing and argues that there are two main hindrances to the plan's success: the dynamics of the current global system and the security complexity of the Caucasus region.

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.

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.

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.

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.

Revenue Management With Minimax Regret Negotiations
(Pergamon-Elsevıer Scıence Ltd, 2016) Ayvaz Çavdaroğlu, Nur; Kachani, Soulaymane; Maglaras, Costis
We study the dynamic bilateral price negotiations from the perspective of a monopolist seller. We first study the classical static problem with an added uncertainty feature. Next, we review the dynamic negotiation problem, and propose a simple deterministic "fluid" analog. The main emphasis of the paper is in analyzing the relationship of the dynamic negotiation problem and the classical revenue management problems; and expanding the formulation to the case where both the buyer and seller have limited prior information on their counterparty valuation. Our first result shows that if both the seller and buyer are bidding so as to minimize their maximum regret, then it is optimal for them to bid as if the unknown valuation distributions were uniform. Building on this result and the fluid formulation of the dynamic negotiation problem, we characterize the seller's minimum acceptable price at any given point in time. (C) 2015 Elsevier Ltd.

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.

The Role of Climate: Implications for Service Employee Engagement and Customer Service Performance
(Springer, 2017) Mengüç, Bülent; Auh, Seigyoung; Yeniaras, Volkan; Katsikeas, Constantine S.
This research attempts to challenge the resource-engagement and engagement-performance linkage of the job demands-resources model by testing these links under the moderating role of two climates: performance-focused and service failure recovery. Two studies test a model on the boundary conditions of the linkages across four service industries. The results suggest that whether a resource (i.e. self-efficacy and job autonomy) positively or negatively affects engagement depends on whether (1) a climate is appraised as a challenge or hindrance demand and (2) a climate is deemed a complementary or compensatory resource. Using multi-respondent data from customer service employees and their supervisors in the health care industry Study 1 conceptualizes climate as organizational climate and finds that performance-focused climate strengthens (weakens) the positive effect of self-efficacy (job autonomy) on engagement while service failure recovery climate weakens the positive impact of self-efficacy on engagement. Study 2 generalizes the findings from Study 1 and provides broad support by testing the model using psychological climate in the financial services tourism and hospitality and retailing industries. This study closes with a configuration approach to climate research by discussing when multiple climates can co-exist under different types of resources.
