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.

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.

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.

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.

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%.

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.

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.

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.
Traditional Folklore Forms İn Temaşa-i Dünya ve Cefakar-u Cefakeş [temaşa-i Dünya ve Cefakar-u Cefakeş´te Geleneksel Folklor Biçimleri]
(Milli Folklor Dergisi, 2016) Şişmanoğlu Şimşek, Şehnaz
Temaşa-i Dünya ve Cefakâr u Cefakeş written by Evangelinos Misailidis in 1871-1872 has widely been considered to be an adaptation of the Greek novel O Polipathis (1839) and its originality has not been adequately emphasized in past studies. This article suggests that Temaşa-i Dünya should be considered an original novel since it incorporates traditional folklore forms peculiar to Ottoman literature which are absent in Polipathis. This study first of all describes the variety and the origins of the traditional folklore forms in Temaşa-i Dünya and delineates the literary tools by the help of which they were included in the text. Furthermore it analyzes how these elements affect the narrative discourse and the author’s purposes in employing them. The analysis demonstrates that in Temaşa-i Dünya oral and print culture materials of both Muslim and non-Muslim origins are embedded in the text primarily in the form of narrative digressions and digressions from the frame story. These digressions carry the marks of the traditional story teller both in terms of functionality and at the discursive level. In other words Misailidis’ narrator being an active subject similar to the story teller in the oral culture chooses and manipulates the appropriate traditional story in accordance with the messages he conveys to the Karamanli readership. It can also be said that unrealistic features of traditional stories are eliminated and the stories are presented in a realistic style and content. Moreover the aforementioned narratives help to overcome the limited perspective of the first person narrative and to portray a variety of experiences. Temaşa-i Dünya also presents a folkloric panorama of 19th century Istanbul through numerous idioms and proverbs.
Corporate Diversification, Grup Affiliation and Firm Value: Evidence From Turkey
(Bankacılık Düzenleme ve Denetleme Kurumu, 2014) Akben Selçuk, Elif
The objective of this study is to investigate the impact of corporate diversification in a sample of 255 Turkish firms for the period between 2006 and 2012. Regression results indicate that diversified firms trade at a premium compared to single-segment firms. To explain this finding, we also investigate the possible moderating role of business group affiliation for the diversification-value relationship. Analysis results reveal that the diversification premium is confined to firms that are not affiliated with business groups. These results suggest that group members already capture the benefits of diversification without the need to diversify further at the firm level.

Service Employee Burnout and Engagement: the Moderating Role of Power Distance Orientation
(Springer, 2016) Auh, Seigyoung; Mengüç, Bülent; Spyropoulou, Stavroula; Wang, Fatima
Studies show that service employees are among the most disengaged in the workforce. To better understand service employees' job engagement this study broadens the scope of the job demands-resources (JD-R) model to include power distance orientation (PDO). The inclusion of PDO enriches the JD-R model by providing a key piece of information that has been missing in prior JD-R models: employees' perceptions of the source of job demands (i.e. supervisors) or employees' views of power and hierarchy within the organization. Study 1 uses a survey-based field study to show that employees with a high (compared to low) PDO feel more burnout due to supervisors when they are closely monitored by their supervisors. Study 1 further supports the finding that employees with high (compared to low) PDO feel less disengagement despite burnout due to supervisors. Study 2 using a lab experiment and Study 3 relying on a survey-based field study unveil why these effects were observed. Stress and job satisfaction emerge as mediators that explain the findings from Study 1. Implications of the role of PDO are discussed to improve the current understanding of how job engagement can improve customer service performance.

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.
"türkiye'de Bireysel Emeklilik Sistemine Katılım Kararını Etkileyen Faktörler"
(İstanbul Okan Üniversitesi, 2017) Aydın, Aslı Elif; Akben Selçuk, Elif
Bu çalışmanın amacı, Türkiye’de bireysel emeklilik sistemine giriş ve otomatik katılımdan cayma kararını etkileyen faktörleri ortaya koymaktır. 130 kişiden kolayda örnekleme ile elde edilen verinin lojistik regresyon yöntemiyle analiz edilmesi sonucu şu bulgulara ulaşılmıştır: Öncelikle, yaş ve gelir düzeyi arttıkça bir bireysel emeklilik planına dahil olma ihtmali artmaktadır. Şimdiki zaman odaklı olan bireylerin bir bireysel emeklilik planına dahil olma ihtimali daha düşük bulunmuştur. Ayrıca, iç kontrol odağına sahip kişilerin bireysel emeklilik planına dahil olma ihtimalleri daha yülsek bulunmuştur. Son olarak, kaçınmacı odak ve bireysel emeklilk sistemine dahil olma ihtimali arasında pozitif ve anlamlı bir ilişki olduğu görülmektedir. Otomatik katılımlı sistemde kalma ihtimalini tahmin eden lojistik regresyon modelinde ise sadece iki değişken anlamlı sonuç vermiştir. Şimdiki zaman odaklı bireylerin cayma ihtimalinin daha yüksek olduğu görülmektedir. Ayrıca hali hazırda isteğe bağlı bir bireysel emeklilik planı sahibi olan bireylerin sistemde kalma ihtimali diğerlerine göre 2.9 kat daha fazla bulunmuştur.

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.
Markaların Sosyal Medya Yardım Masası Hesaplarına Yapılan Şikayetlerin Analizi: Yüksek Teknoloji Ürünleri Üzerine Bir Çalışma
(Melih Topaloğlu, 2018) Önden, Abdullah; Kiygi Calli, Meltem
Bu araştırmada marka müşterilerinin satın alıp kullandıkları ürünlerle ilgili istek ve şikayetlerini ilettikleri çevrimiçi yardım masalarıyla olan etkileşimi incelenerek markaların şikayetlere nasıl yanıt verdikleri ve uyguladıkları şikayet yönetiminin müşterilerin duygularındaki değişimi nasıl etkilediği araştırılmış ve sosyal medya ağlarından elde edilen veriler duygu analizi yöntemiyle analiz edilmiştir. Çalışmada müşterilerin istek ve şikayetlerini ilettikleri paylaşımlarındaki tutumlarının duygusal değerinin ne olduğu, çevrimiçi yardım masasının konuyu nasıl ele aldığı ve çevrimiçi yardım masası ile olan etkileşimin uzunluğunun (soru ve cevap iletişiminin sayısı) tutum ve duygusal değeri nasıl etkilediği incelenmiştir. Araştırmanın sonuçlarına göre çalışmada ele alınan markaların kendilerine çevrimiçi yardım masaları üzerinden iletilen talep ve şikayetleri ivedilikle çözdükleri belirlenmiştir. Büyük markalar hizmet telafisi paradoksu teorisine göre hareket edip ürünleri hakkında sorun yaşamış ve ürün hakkında şikayette bulunmuş müşterilerini mutlu etmektelerdir. Böylece bu müşterilerin sadık müşterilere dönüştükleri sonucuna varılmaktadır.
