Applying a Behavioural and Operational Diagnostic Typology of Competitive Intelligence Practice: Empirical Evidence From the Sme Sector in Turkey
(Taylor and Francis Group, 2012) Wright, Sheila; Bisson, Christophe; Duffy, Alistair P.
This paper reports on an empirical study conducted within the SME sector in the city of Istanbul Turkey. The findings from this study enabled the creation of a behavioural and operational typology of competitive intelligence practice one developed from the work of S. Wright D.W. Pickton and J. Callow (2002. Competitive intelligence in UK firms: A typology. Marketing Intelligence & Planning 20 349-360). Using responses to questions which indicated a type of behaviour or operational stance towards the various strands of CI practice under review it has been possible to identify areas where improvements could be made to reach an ideal situation which could garner significant competitive advantage for the SMEs surveyed. © 2012 Copyright Taylor and Francis Group LLC.

Art Investment: Hedging or Safe Haven Through Financial Crises
(Springer, 2020) Öztürkkal, Belma; Toğan-Eğrican, Aslı
We analyze long-term art auction sales data focusing on and around financial crisis periods with other investment returns to understand whether art can be considered a safe haven during volatile times or a hedging option in general by analyzing art auction data in a volatile emerging market. Our findings suggest Turkish art returns are either negatively correlated or at low correlation with other investments, including the equity market. We have the view that art can be considered a hedging mechanism on average to enhance returns and to decrease the risk of portfolios and improve diversification. However, we do not discard the safe-haven hypothesis, either. Although the auction data on the crisis period is limited, results of and around crisis periods show art returns are positively correlated with various volatility indices. In addition, the number of art transactions also increases after the crisis years, which may be a sign of liquidity requirement of some investors and an opportunity for buyers. The benefit is visible especially during years of contractions, which do not end with a very severe crisis, since the art auction market liquidity dries if the crisis is severe.

Assessing Quality in Higher Education: New Criteria for Evaluating Students' Satisfaction
(Taylor & Francis, 2011) Zineldin, Mosad; Akdag, Hatice Camgöz; Vasicheva, Valentina
The aim of this research is to present a new quality assurance model (5Qs) and to examine the major factors affecting students' perception of cumulative satisfaction. The model includes behavioural dimensions of student satisfaction. The factors included in this cumulative summation are technical functional infrastructure interaction and atmosphere of higher education institutions. This study concerns students in higher education institutions in Istanbul Turkey. The questionnaire contains a total of 39 items (attributes) of newly developed five quality dimensions (5Qs). A total of 1641 complete and usable questionnaires was received. Frequency analysis factor analysis and reliability analysis were used for analysing the data collected. Inspection of scree plot and eigenvalues enabled the analysis to reduce the 39 quality attributes to seven factors. The results can be used by higher education institutions to re-engineer and re-design creatively their quality-management processes and the future direction of their more effective education quality strategies. © 2011 Taylor & Francis.

Assessment of Chromite Liberation Spectrum on Microscopic Images by Means of a Supervised Image Classification
(Elsevier Science Bv, 2017) Camalan, Mahmut; Çavur, Mahmut; Hosten, Cetin
Assessment of mineral liberation spectrum with all its aspects is essential for plant control and optimization. This paper aims to estimate 2D mineral map and its associated liberation spectrum of a particular chromite sample from optical micrographs by using Random Forest Classification a powerful machine-learning algorithm implemented on a user-friendly and an open-source software. This supervised classification method can be used to accurately generate 2D mineral map of this chromite sample. The variation of the measured spectra with the sample size is studied showing that images of 200 particles randomly selected from the optical micrographs are sufficient to reproduce liberation spectrum of this sample. In addition the 2D spectrum obtained with this classification method is compared with the one obtained from the Mineral Liberation Analyzer (MLA). Although 2D mineralogical compositions obtained by the two methods are quite similar microscopic analysis estimates poorer liberation than MLA due to the residual noise (misclassified gangue) generated by the classification. Nevertheless we cannot compare the reliabilities of the two methods as there is not a standard produce yet to quantify the accuracy of MLA analysis. (C) 2017 Elsevier B.V. All rights reserved.

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.

A Behavioral Analysis of Investor Diversification
(Routledge Journals Taylor & Francis Ltd, 2014) Fuertes, Ana-Maria; Muradoğlu, Gülnur; Öztürkkal, Belma
This paper studies the link between individual investors' portfolio diversification levels and various personal traits that proxy informational advantages and overconfidence. The analysis is based on objective data from the largest Turkish brokerage house tracking 59951 individual investors' accounts with a total of 3248654 million transactions over the period 2008-2010. Wealthier highly educated older investors working in the finance sector and those trading relatively often show higher diversification levels possibly because they are better equipped to obtain and process information. Finance professionals married investors and those placing high-volume orders through investment centers show poorer diversification possibly as a reflection of overconfidence. Our analysis reveals important nonlinear effects implying that the marginal impact of overconfidence on diversification is not uniform across investors but varies according to the investor's information gathering and processing abilities.

Competition in Turkish Banking: Impacts of Restructuring and the Global Financial Crisis
(Wiley, 2014) Yıldırım, Canan
This paper investigates the evolution of competition in the Turkish banking industry by taking into account the transformation in the sector in the aftermath of the country's financial crisis of 2000 to 2001 and the global financial crisis. The results demonstrate that the level of competition in the system did not increase despite the restructuring that was undertaken and the increased foreign bank participation. In addition the level of competition in the sector deteriorated during the global crisis. There is also some evidence that the market power of banks with different ownership characteristics varied and did not converge over time.

A Competitive Intelligence Practices Typology in an Airline Company in Turkey
(Springer, 2020) Şahin, Murat; Bisson, Christophe
Oil prices, political instabilities, travel legislations, and many other competitive factors make it essential for any international airline with the instinct to survive to be on constant watch in such a fiercely competitive environment. To meet this need, it is vital for international airline companies to integrate competitive intelligence (CI) into their strategy building process. In this study, we create for the first time a typology of competitive intelligence practices of an international airline company (in Turkey), based on the model developed by (Wright et al.Journal of Strategic Marketing, 20(1), 19-33,2012), and it is one of the very first to investigate Competitive intelligence in this sector. Furthermore, we made a two-step cluster analysis to uncover hidden clusters that change the way of thinking within the company. Our findings show where the company would need to make improvements on the 6 strands of the model which are attitude, gathering, use, location, technological support, and IT support. Yet, that could lead towards stronger business performance. It might also inspire other companies of the airline sector and beyond.

Corporate Social Responsibility and Financial Performance: the Moderating Role of Ownership Concentration in Turkey
(MDPI, 2019) Akben Selçuk, Elif
The objective of this study is to investigate the impact of corporate social responsibility (CSR) engagement on firm financial performance in a developing country, Turkey, and to analyze the moderating role of ownership concentration in the CSR-financial performance relationship. The sample consists of non-financial public firms listed on the Borsa Istanbul (BIST)-100 index and covers the period between 2014 and 2018. Empirical results using an instrumental variable approach show that corporate social responsibility has a positive relationship with financial performance. Furthermore, findings indicate that this relationship is negatively moderated by ownership concentration even when endogeneity is controlled for.

Developing a Measure for "connectorship" as a Component of Engaged Leadership
(Emerald Group Publishing Ltd, 2016) Dastmalchian, Ali; Rezac, Darcy; Muzyka, Daniel F.; Bayraktar, Seçil; Steinke, Claudia; İmer, Havva Pınar
Purpose - The purpose of this paper is to report the findings of a mixed methods study that explored how active community engaged and connected managers were in their local and broader communities (engaged leadership, EL). The paper specifically investigates an under researched aspect of EL - "connectorship" - with focus on developing a measure for connectorship. The authors present the conceptual framework for EL, followed by the operationalization of "connectorship" construct. Design/methodology/approach - The paper focusses on developing a measure for connectorship using data from a qualitative study of 18 senior managers followed by a survey of 458 managers in Canada. Findings - Content analyses of qualitative data led to the generation of 93 items measuring connectorship. Based on these items, quantitative analyses of survey data from 453 respondents yielded a final measure of connectorship, which consisted of 28 items explored under eight dimensions. Research limitations/implications - An organization's emphasis on connectedness and engagement of leaders will improve knowledge sharing and better mutual understanding of organizational issues among managers. It will also help attain employment stability and decrease hiring and related costs by reducing turnover. Future research, specifically longitudinal studies of leaders at various organizational levels, could incorporate connectorship as a key criterion for leadership effectiveness. Practical implications - The focus on connectorship skills implies that in organizations the emphasis should go beyond traditional leadership skills development and included the neglected connectorship skills development. Increased connectedness and engagement among leaders will have positive performance implications. Social implications - For effective corporate citizenship, the EL framework and a focus on connectorship would help leaders better understand the importance of social networks, be aware of their own network, and improve their skills in connecting the people within their networks. Originality/value - Using a variable centered approach within the framework of EL the paper contributes to leadership literature by conceptually defining connectorship developing a measure for this construct and testing its psychometric properties.
Diffusion of Pure and Hybrid Forms of a Practice: Language of Instruction in Turkish Universities, 1983-2014
(Wiley Periodicals, Inc, 2020) Topaler, Başak; Üsdiken, Behlül
It is well recognized in the literature that practice variation is an integral part of diffusion processes. What remains less explored is the emergence of distinct forms of a novel practice and the interdependencies in their diffusion. In this study, we make a distinction between the pure version of a practice and ensuing hybrid variants and investigate how diffusion processes unfold for these alternative practice forms. Our empirical investigation in the Turkish higher education field demonstrates that hybrid practice forms became viable alternatives to the pure version of instruction in English and diffused in an interdependent manner. Further, diffusion of pure and hybrid forms was uneven across private and public universities. Our study contributes to the diffusion and practice variety literature as we establish that multiple versions of a practice that diffuse concurrently in a field may be building on or hampering each other, and they may diffuse in fragmented ways across different sub-populations.

Does Firm Age Affect Profitability? Evidence From Turkey
(Int Inst Social & Economics Sciences-IISES, 2016) Akben Selçuk, Elif
The objective of this study is to investigate the impact of firm age on the profitability of Turkish firms listed on Borsa Istanbul. Using a dataset covering the years between 2005 and 2014 and consisting of 302 non-financial firms per year on the average a fixed effects model with robust standard errors is estimated. Results reveal that there is a negative and convex relationship between firm age and profitability measured by return on assets return on equity or gross profit margin. This suggests that younger firms start to see a decline in their profitability from the beginning but they may become profitable again at an old age. Implications are provided.

Efficiency Analysis of Black Sea Container Seaports: Application of an Integrated Mcdm Approach
(Routledge, 2020) Ömer Faruk, Görçün
The current paper carries out an examination about the selection of the proper container seaport, which in the Black sea region. This paper focuses on a research question. Is it possible to apply multi-criteria decision-making methods that can be applied more easily than the DEA technique for decision-makers? In order to determine the best performance analysis technique that can give successful results, two-hybrid multi-criteria decision-making models were selected and operational performances of the container ports in the Black Sea region were analyzed with the help of these integrated approaches. While the first MCDM model consists of the entropy and OCRA technique, the second hybrid model consists of the Entropy and EATWIOS method. The main aim of this paper is to discuss whether these proposed hybrid models can be implemented to make an effective performance analysis for the maritime industry. The second aim of this paper is to evaluate the Black sea container seaports with the help of this suggested model. The study reveals that the proposed MCDM models can be implemented for container port selection successfully and easily and both of them have given very closer results to each other in aspects of the evaluation of the criteria and options.

Efficiency in Turkish Banking: Post-Restructuring Evidence
(Routledge Journals Taylor & Francis Ltd, 2017) Davutyan, Nurhan; Yıldırım, Canan
Turkish banking sector went through a significant restructuring process in the aftermath of the country's financial crisis of 2000-2001. In this paper we analyze the evolution of banking performance using a novel approach due to Ray [(2007). Shadow Profit Maximization and a Measure of Overall Inefficiency. Journal of Productivity Analysis 27 231-236]. We derive shadow unrealized profit scores' as well as shadow input-output prices' for each year and bank in the sector from 2002 to 2011. We argue these scores operationalize the Hicksian concept of monopolistic quiet life'. We provide some evidence the sector came closer to the zero profit condition' as well as displaying a closer approximation to the law of one price' over time. We show the variability of these shadow prices' essentially coincides with that of corresponding actual prices. We utilize shadow price information to show that business models and competitive choices of banks differ across ownership types with foreign banks competing on the broadest front compared to state-owned and privately owned Turkish banks.

Exploring the Impact of Sustainability on Corporate Financial Performance Using Discriminant Analysis
(MDPI, 2020) Keskin, Ayşe İrem; Dinçer, Banu; Dinçer, Caner
The impact of sustainability on corporate financial performance has been an important subject of both academic and professional debate since the 1990s. However, there is a lack of consensus in the literature, and studies from developing countries remain scarce. Accordingly, this study uses discriminant analysis to shed light on the variables that discriminate between sustainable and non-sustainable companies using the companies included in Borsa Istanbul (BIST100) (Istanbul Stock Exchange) and the Borsa Istanbul Sustainability Index for a three-year period. Financial and market variables are used in the analysis. Financial variables include the return on equity (ROE), return on assets (ROA), leverage ratios, and company size. The analysis also incorporates market variables such as alpha, beta, volatility, earnings per share, and the price to book ratio. The results show that the relationship between sustainability and performance is significantly influenced by the company size, leverage, volatility, and price to book ratio. The large companies are considered to be more sustainable as their commitment is well recognized. In this way, they attract more investors. Therefore, their stock prices are less volatile and achieve a better price to book ratio. They obtain easy access to external financing compared to companies considered to be non-sustainable. Moreover, they are less volatile in the market and better valued by investors.

Factors Affecting Firm Competitiveness: Evidence From an Emerging Market
(MDPI, 2016) Akben Selçuk, Elif
The objective of this study is to investigate the factors affecting firm competitiveness in an emerging marketTurkey. In the paper competitiveness is proxied by a firm's financial performance. The empirical analysis is based on firms listed on Borsa Istanbul and covers the period between 2005 and 2014. Results from a firm-level panel data model indicate that return on assets is positively related to firm size international sales liquidity and growth and negatively related to leverage and R&D expenditures. On the other hand gross profit margin is positively related to size and international sales and negatively related to leverage and R&D expenditures. Finally results show that Tobin's Q ratio is higher for firms with higher levels of debt and higher liquidity levels.

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.

Financial Inclusion and Bank Stability: Evidence From Europe
(Routledge Journals, 2020) Danışman, Gamze Öztürk; Tarazi, Amine
The Great Recession of 2007-2009 piqued the interest of policymakers worldwide, prompting various initiatives to stabilize the financial system and advance financial inclusion. However, few studies have considered their interconnectedness or whether any synergies or trade-offs exist between them. This paper investigates how financial inclusion affects the stability of the European banking system. The findings indicate that advancements in financial inclusion through more account ownership and digital payments have a stabilizing effect on the banking industry. A deeper investigation shows that such a stabilizing impact is mainly driven by the targeting of disadvantaged adults who are young, undereducated, unemployed, and who live in rural areas. Hence, along with its known benefits to society as a whole, financial inclusion has the additional benefit of improving the stability of the financial system. Such findings call for policy configurations that are specifically designed to achieve financial inclusion for disadvantaged individuals.

Financial Literacy Among Turkish College Students: the Role of Formal Education, Learning Approaches, and Parental Teaching
(Ammons Scientific Ltd, 2014) Akben Selçuk, Elif; Altıok-Yılmaz, Ayşe
This study assessed financial literacy and its correlates among Turkish college students with special emphasis on the role of formal education learning approaches and parental influences. Financial literacy was measured by the College Student Financial Literacy Survey which assesses knowledge in four areas: general financial management saving and borrowing insurance and investing. 853 Turkish university students were administered the survey (416 men 437 women ; M age = 20.3 yr. SD = 0.6). The mean percentage of correct responses was 45% (SD = 12.8%). Regression results showed that formal finance education in college a deep approach to learning and direct financial teaching by parents were significantly associated with higher financial literacy scores.
