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.

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.

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 governance affect corporate diversification behaviour in emerging markets?
(Routledge Journals, Taylor & Francıs Ltd, 2020) Sener, Pınar; Akben Selçuk, Elif
This paper investigates the role of firm-level and country-level governance on corporate diversification behaviour in emerging markets. The results show that firms with combined leadership structure are more diversified while firms with more independent directors are less diversified. There is a U-shaped relationship between ownership concentration and diversification. No significant association between country-level shareholder protection and diversification is demonstrated.

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.

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.

Informed trading, order flow shocks and the cross section of expected returns in Borsa Istanbul
(Routledge Journals, 2020) Tiniç, Murat; Salih, Aslihan
This paper examines the relationship between information asymmetry and stock returns in Borsa Istanbul. For all stocks that are traded in Borsa Istanbul between March 2005 and April 2017, we estimate the probability of informed trading (PIN) to proxy for information asymmetry.? Firm-level cross-sectional regressions indicate a statistically insignificant relationship between PIN estimates and future returns. Moreover, univariate and multivariate portfolio analyses assert that investors that hold stocks that have high information asymmetry do not obtain significant future returns. Consequently, our results suggest that information asymmetry proxied by PIN is a firm-specific risk and can be eliminated with portfolio diversification. Findings are robust to different factorizations in estimating PIN and free of any bias due to trade classification algorithms, boundary solutions, floating-point exceptions and symmetric?order flow shocks.

Internal Customer Satisfaction Improvement with QFD Technique
(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.

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.

The maximum surplus in a finite-time interval for a discrete-time risk model with exchangeable dependent claim occurrences
(John Wiley and Sons Ltd, 2019) Gebizlioğlu, Ömer Lütfi; Eryilmaz, Serkan
This paper investigates a discrete-time risk model that involves exchangeable dependent loss generating claim occurrences and compound binomially distributed aggregate loss amounts. First a general framework is presented to derive the distribution of a surplus sequence using the model. This framework is then applied to obtain the distribution of any function of a surplus sequence in a finite-time interval. Specifically the distribution of the maximum surplus is obtained under nonruin conditions. Based on this distribution the computation of the minimum surplus distribution is given. Asset and risk management–oriented implications are discussed for the obtained distributions based on numerical evaluations. In addition comparisons are made involving the corresponding results of the classical discrete-time compound binomial risk model for which claim occurrences are independent and identically distributed. © 2018 John Wiley & Sons Ltd.

Social Media Adoption: A Process-Based Approach
(Taylor & Francis Inc, 2016) Toker, Ayşegül; Seraj, Mina; Kuşçu, Asli; Yavuz, Ramazan; Koch, Stefan; Bisson, Christophe
This research conceptualizes and measures social media adoption (SMA) of companies with a process-based approach and explains its antecedents of micro- and macro-environment size and ownership as well as its consequence of intention to increase resources dedicated to social media. Based on data from 310 Turkish small and medium enterprises the study first develops a conceptual framework on the pillars of internal and external stakeholder focus as well as relationship and information oriented implementation. Based on these two dimensions it discusses the novel concepts of social customer relations social stakeholder communication social intelligence and social responsiveness related to SMA. The study further indicates that ownership type and micro environment play a role in SMA and that path dependence exists in the interplay of current adoption and future intentions.
