Conference Object Analyzing the Effect of Antecedents of Turnover Intention According To Generations(Future Acad, 2019) Karabay, Melisa Erdilek; Seiler, Irge; Elci, Meral; Ensari, SebnemThere are many predictors that determine the turnover intention of employees. Among these predictors, mobbing behaviour can be disruptive in the workplace since workplace deviance is a matter which most organizations wrestle today. Organizational commitment is an important variant for employees to achieve organizational success whereas ethical climate is the picture of an organization which demonstrates its' moral philosophy. This study examines the main effects of ethical climate, mobbing, and organizational commitment in predicting turnover intention among the sample of 166 employees, working in a municipality, particularly in Istanbul province, Turkey. The findings indicate that mobbing affect turnover intention positively, while ethical climate has no effect in estimating turnover intention. Study results also suggest that commitment (continuance and affective) is also found to be negatively related to turnover intention of employees. In addition, for Generation-X members, continuance commitment and for Generation-Y members, affective commitment has a significant effect on turnover intention.

When identifying this potential, the clustering tendencies of companies with input-output relations and included in the value chain were also used in addition to survey data. At the end of the study, according to the data obtained through the AHP and the surveys held in 10 provinces, two provinces came to fore, meeting the highest number of criteria in terms of clustering potential. These are the provinces of Istanbul and Gaziantep. The provinces of Izmir and Bursa were identified as being closer to having a clustering potential compared to other provinces. In addition, it is expected that this study will make a significant contribution to literature as this study uses the AHP method for the first time in identifying the potential of clustering.Conference Object Citation - WoS: 13Board Composition and Gender Diversity: Comparison of Turkish and Nigerian Listed Companies(Elsevier Science Bv, 2014) Karaye, Abubakar Balarabe; Sener, IrgeThe research related with board of directors is an important research stream. One of the most noteworthy dimensions related with board composition is board gender diversity. Although, many research is undertaken in developed countries related with board gender diversity, related research is still at infancy in developing and emerging market economies. This study aims to contribute to the literature by comparison of important board composition dimensions, that are board gender diversity, presence of independent directors and board size between Turkey and Nigeria. The findings indicate no statistically significant difference between the two countries in terms of board gender diversity and underrepresentation of female directors. According to the research findings, the underrepresentation of female directors is more obvious in Turkey. On the other hand, there exists statistically significant difference in terms of board size and presence of independent board members among the two countries. (C) 2014 The Authors.

Despite that extensive research was conducted, the understanding of the board and its effects is still limited. This is mainly because that the majority of the corporate governance research focused mostly on the direct relation of board characteristics with organizational outcomes, and neglected the effect of intervening variables, leading to inconclusive research findings. Deriving on this limitation, in this study, the effect of board composition on organizational performance was investigated for different environmental conditions, which are measured in terms of munificence and dynamism of the industry in which the organizations operate and product complexity of the organizations. In addition, the moderating effects of these dimensions of organizational task environments on the relationship between board composition and organizational performance were also addressed. Building on resource dependence theory, it is suggested that under different environmental conditions, different compositions of boards will positively influence organizational performance. Based on the data from 80 companies which shares are publicly traded in Istanbul Stock Exchange, the findings indicate that the effect of board composition on organizational performance vary among different environmental conditions.

The two main goals of this study were to explore whether gender was a significant predictor of compulsive buying behavior and to determine the effect of two particular predispositional factors ( anxiety, depression) on compulsive buying. The primary data for this study was obtained from a questionnare that was administered in the capital city of Ankara. A convenience sample of three hundred and fourteen respondents participated in the study. Independent sample t - test, correlational and regression analyses were conducted for data analysis. The empirical findings showed that there are marked differences in compulsive buying tendencies of Turkish women and men, and factors such as age and anxiety are strongly related to compulsive buying behavior.Article Citation - WoS: 18Citation - Scopus: 23Computing Non-Stationary (S, S) Policies Using Mixed Integer Linear Programming(Elsevier Science Bv, 2018) Xiang, Mengyuan; Rossi, Roberto; Martin-Barragan, Belen; Tarim, S. ArmaganThis paper addresses the single-item single-stocking location non-stationary stochastic lot sizing problem under the (s, S) control policy. We first present a mixed integer non-linear programming (MINLP) formulation for determining near-optimal (s, S) policy parameters. To tackle larger instances, we then combine the previously introduced MINLP model and a binary search approach. These models can be reformulated as mixed integer linear programming (MILP) models which can be easily implemented and solved by using off-the-shelf optimization software. Computational experiments demonstrate that optimality gaps of these models are less than 0.3% of the optimal policy cost and computational times are reasonable. (C) 2018 Elsevier B.V.

Armagan; Prestvvich, StevenIn this work we introduce a novel approach, based on sampling, for finding assignments that are likely to be solutions to stochastic constraint satisfaction problems and constraint optimisation problems. Our approach reduces the size of the original problem being analysed; by solving this reduced problem, with a given confidence probability, we obtain assignments that satisfy the chance constraints in the original model within prescribed error tolerance thresholds. To achieve this, we blend concepts from stochastic constraint programming and statistics. We discuss both exact and approximate variants of our method. The framework we introduce can be immediately employed in concert with existing approaches for solving stochastic constraint programs. A thorough computational study on a number of stochastic combinatorial optimisation problems demonstrates the effectiveness of our approach. (C) 2015 Elsevier B.V.

We also explore channels through which the degree of financial liberalization impacts aggregated total volatility. We document a negative relation to the degree of financial liberalization after controlling for size, liquidity, country. and crisis effects, especially for small and medium-sized markets. Moreover, the degree of financial liberalization transmits its negative impact on aggregated total volatility through aggregated idiosyncratic and local volatilities. Overall, our results provide evidence in favor of the view that the broadening of the investor base due to the increasing degree of financial liberalization causes a reduction in the total volatility of stock returns.

Mete; Aktas, RamazanThis paper aims to develop methods that are capable of detecting manipulation in the Istanbul Stock Exchange. We take the difference between manipulated stock's and index's average daily return, average daily change in trading volume and average daily volatility and used these statistics as explanatory variables. The data in post-manipulation and pre-manipulation periods are used as non-manipulated instances while the data in the manipulation period are used as manipulated instances. Test performance of classification accuracy, sensitivity and specificity statistics for Artificial Neural Networks (ANN) and Support Vector Machine (SVM) are compared with the results of discriminant analysis and logistics regression (logit). We found that the data mining techniques (ANN and SVM) are better suited to detect stock-price manipulation than multivariate statistical techniques (discriminant analysis, logistics regression) as the performances of the data mining techniques in terms of total classification accuracy and sensitivity statistics are better than those of multivariate techniques. We also found that unit change in difference between average daily return of manipulated stock and the index has the largest effect while unit change in difference between average daily change in trading volume of manipulated stock and index has the least effect on multivariate classifiers' decision functions.

The economic level and conditions combined with the student's potential make itself felt at the ultimate level. In this research, it was established that success and socio-economic factors which can attract the attention are effectively observed on particularly female students. It was ensured that a real and sound socio-economic criteria for success be determined by evaluating success and failure at terminal points. Decision trees and chi-square test were used in the implementation.Article Discussing the Role of Trust in Behavioral Assumptions of Transaction Cost Theory(Igiad-turkish Entrepreneurship & Business Ethics Assoc, 2013) Kalemci, Rabia ArzuIn its attempts to explain organizations based on their economical approach, transaction cost theory has a unique position among all organizational theories since it derives its assumptions from human behaviors. The basic behavioral assumptions of transaction cost theory are "opportunism" and "bounded rationality." Transaction cost theory includes a selection of governance mechanisms whose goal is to minimize transaction costs based on the aforementioned behavioral assumptions. This study discusses the notion that not only is "trust" one of the most important aspects of work ethics, but that it is also disregarded by the abovementioned governance mechanisms of transaction cost theory. This study also underlines the importance of building an environment of trust in an organization rather than selecting governance mechanisms under an "opportunist" and "bounded rational" paradigm, as is currently the case in transaction cost theory.Article Citation - WoS: 8Citation - Scopus: 6Does Adr Listing Affect the Dynamics of Volatility in Emerging Markets(Charles Univ-prague, 2010) Umutlu, Mehmet; Umutlu, Mehmet; Altay-Salih, Aslihan; Akdeniz, Levent; İşletmeThis paper analyzes the time-series variation in the return volatility of non-US stocks from emerging markets that are cross-listed on US exchanges. Unlike previous studies in the cross-listing literature, return volatility is modeled using conditional heteroscedaslicity models. We find that firms' exposure to risks such as local and global market betas remain unchanged after cross-listing. Moreover, we do not identify notable changes in the dynamics of the volatility of cross-listed stocks after cross-listing except for leverage effects. We further show that the mean level of conditional variance is not affected after cross-listing. Thus, our results provide counter-evidence to the belief that foreign investor participation drives volatility upward.Article Citation - WoS: 7Citation - Scopus: 8Does Workplace Envy Always Have Detrimental Consequences in Organizations? a Study of Public and Private Sector Employees(Emerald Group Publishing Ltd, 2022) Karabay, Melisa Erdilek; Elci, Meral; Erman, Halil; Sener, IrgePurpose Based on the situational approach for envy, the purpose of this paper is to examine the effect of two-dimensional workplace envy (being envied and envying others) on the task and contextual performance of employees working in either private or public sector organizations. Design/methodology/approach This study was conducted on survey data collected from 988 private sector employees and 530 employees from the public sector employed in Istanbul. Following a quantitative empirical design, structural equation modeling was used to test the hypotheses. Findings The study results revealed that envying-others dimension has a significant negative effect on both task performance and contextual performance. In addition, the findings indicate more envious feelings of private sector employees than public sector employees. For public sector employees, male participants were found to envy others more than females. Research limitations/implications In addition to the contributions, this study has its limitations. First, although the study was carried out with a comprehensive sample, it is limited to the views of 1,518 employees in Istanbul and is a cross-sectional study. Also, employee performance is evaluated through self-reporting, which forms another limitation; it could have been more reliable for the supervisors to assess their subordinates' performance. Practical implications Apart from scholars, our findings have implications for practitioners. Feelings such as envy that comes with a sense of competition can create an environment that stimulates people, motivates them to work, can make them productive and can also cause an ultimately destructive situation. This makes it critical to manage envy in the workplace. Though there may be facilitators behind it, one crucial factor that fuels envy in the workplace is the lack of fair human resources policies and systems. Still, human resources management is undeveloped in most public organizations. With effective human resources management, there may be some roadmaps for managers to dissolve conflicts arising from envy. First, it is imperative to have systems that will separate the employee from the others, which everyone will accept, strengthening the feelings of justice among employees. Envy often occurs following a social comparison. Management can implement an incentive system that supports employee collaboration and avoid nepotism. Especially in private organizations where the competition is more among employees, managers should give more attention to understand their subordinates' feelings. The managers' attention to expressing their feelings toward their subordinates could establish an equal distance within the workplace. In this sense, language selection is critical, and managers should be mindful of linguistic triggers. Managers should not avoid giving both positive and negative feedback to their employees. Unwarranted and unsystematic reward and/or punishment systems, made with the good intentions of increasing competition, can trigger envy. Finally, managers should implement an open-door policy and open communication that will encourage all team members to be transparent to each other. Originality/value The study was based on a rationale that envy has detrimental workplace outcomes that lead to low task and contextual performance. Although there exists a recent interest for examining the relation between workplace envy and employee performance, based on being envied and envying others dimensions, these studies are limited. This study focuses on these dimensions and performance relations, and it also provides a comparative outlook for public and private sector employees in Turkey in terms of workplace envy.Conference Object The Effect of Knowledge Economy on Organizational Environments: Do the Governance Mechanisms Differ According To Institutional and Technical Environments(int Business information Management Assoc-ibima, 2009) Sener, Irge; Şener, İrge; İşletmeTechnological developments result in important changes for organizations and their environment. The most remarkable change in the organizational field is the widespread usage of Internet, a new information and communication technology (ICT). The changes depending on Internet, affect organizational structures, since they are designed compatible to the communication needs dependent on the technology. In some cases, however, the communication technologies can be developed in consistence with the organizational structure. This indicates that, when ICTs are taken into consideration, it occurs that there is no clear distinction between technical and institutional organizational environments. The ICTs dependent on Internet is both a legitimacy source for the organizations and an efficiency tool. Accordingly, in this study it is considered that the technical and institutional environments are interpenetrated and different types of governance mechanisms result due to the varying effects of the environmental pressures. Testable propositions are developed for different types of environments.Conference Object Citation - WoS: 8The Effect of Organizational Culture on Organizational Image and Identity: Evidence From a Pharmaceutical Company(Elsevier Science Bv, 2013) Bingol, Dursun; Sener, Irge; Cevik, EminEvery organization has its own distinct organizational culture that is fundamental for organizational identity of employees and the perceptions of organizational image. In this study, it is aimed to understand the relations of organizational culture, identity and image within a regional office of a pharmaceutical company. Three different surveys, each focusing on a different dimension, are conducted with all of the 10 managers of the regional office, 30 employees and 85 customers of the company. The findings of the research demonstrate the presence of a hierarchy culture, moderate level of organizational identity for employees and image perceptions based on R&D for the employees and brand for the customers. In the light of the findings, it is evaluated that there exists a need for change of the present organizational culture.Conference Object Citation - WoS: 21The Effects of Organizational Justice and Ethical Climate on Perceived Work Related Stress(Elsevier Science Bv, 2014) Elci, Meral; Uslu, Tanyeri; Sener, Irge; Sert, ArzuStress leads to negative consequences for employees and organizations. Therefore, understanding the relation of stress with other variables is important. This paper examines the relationship between organizational justice, ethical climate and perceived work Related Stress. According to the findings from 915 employees, there exists a significant negative relationship between distributional and procedural justice and work related stress. In addition, ethical climate also has a negative effect on work related stress. With this study, it can be inferred that development of ethical climate and organizational justice within the organizations help to decrease the work related stress of employees.

Study also aims to test the indirect effects of perceived person-organization fit and psychological ownership on the relationship between paternalistic leadership and employee task performance, through serial mediation models. Furthermore, the moderating role of organizational size in direct and all indirect relations between paternalistic leadership and task performance, through five different models is tested. Sample consists of 1,652 employees from various industries in Istanbul, Turkey. Hypothesized relationships were tested through structural equation modelling. The findings demonstrated the significant positive direct relationship between paternalistic leadership and employee task performance. Psychological ownership mediated the relationship of paternalistic leadership and task performance while person-organization fit had no mediating effect. Practical implications and further recommendations are also discussed.Article Citation - WoS: 30Citation - Scopus: 34Employee Deviant Behavior: Role of Culture and Organizational Relevant Support(Emerald Group Publishing Ltd, 2019) Kalemci, R. Arzu; Kalemci-Tuzun, Ipek; Ozkan-Canbolat, ElaPurpose The purpose of this paper is to increase the knowledge and understanding of organizational and supervisory support in the context of employee deviant workplace behavior (DWB) by examining the potential associations of employees' cultural value orientations. This paper aims to: clarify DWB; review perceived organizational support (POS) and perceived supervisory support (PSS); discuss the meaning of employees' cultural value orientations (individualism-collectivism, power distance and paternalism); use the fuzzy logic model to analyze relationships between DWB and POS, as well as PSS and employees' cultural value orientations. Design/methodology/approach This research applies a fuzzy-set qualitative comparative analysis. Findings The results show the role of employee perceived organizational and supervisory support and cultural dimension (power distance and paternalism) configurations on employee DWB. Originality/value The main originality of this study is to further increase the understanding of organizational and supervisory support in the context of employee DWB by examining the potential associations of employees' cultural value orientations. This study extends the previous research by providing evidence that organizational and supervisory support influences employees' DWB.Book Part Citation - WoS: 3Citation - Scopus: 4Entry Barriers To the Nanotechnology Industry in Turkey(Igi Global, 2010) Sener, Irge; Aydogan-Duda, NeslihanNanotechnology is the science that focuses on the control of matter at the atomic scale. It has the potential to create many new materials and devices with wide-ranging applications, such as in medicine, electronics and energy production. There are many entry barriers which can affect nanotechnology penetration in developing and emerging nations. This chapter discusses such barriers for Turkey. Despite about 10 universities having nanotechnology programs, the number of nanotechnology firms in the country is still low. Using combinations of interviews, surveys and literature, these issues that continue to stall the commercialization of discoveries in Turkey are examined.
