    Analysis of Personal Information Security Behavior and Awareness
    (2016) Ogutcu, Gizem; Tastik, Ozlem Muge; Chouseinoglou, Oumout; AAD-2902-2020
    Hardware and software security mechanisms are widely used to strengthen information systems (IS) against attacks. However, these systems are still highly vulnerable to threats from users' undesirable behaviors, which are closely related to IS users' information security awareness. This study has been carried out in an effort to investigate the IS users' risky behaviors that may threaten information security. The preventive actions employed by users, the threats they may be exposed to, or whether they had an adverse experience or to what extent they perceive risks have also been investigated. Four scales: Risky Behavior Scale (RBS), Conservative Behavior Scale (CBS), Exposure to Offence Scale (EOS) and Risk Perception Scale (RPS), were developed depending on the data collected with the use of surveys. The scales developed from the content of the survey were applied to students, academics and administrative staff of a university, which also embodies hospitals and educational organizations located in different geographical and socio-economical regions of Turkey. On the base of developed scales, the results of the study show that there are significant differences within samples and according to the habits of Internet usage. (C) 2015 Elsevier Ltd.

    Transformation of Islamic Work Ethic and Social Networks: The Role of Religious Social Embeddedness in Organizational Networks
    (2016) Kirkbesoglu, Erdem; Sargut, Ali Selami; 0000-0002-6781-9753; 0000-0002-9337-1673; ABI-3973-2020; U-4137-2018
    The aim of this study is to explore the influence of religious beliefs on social or work-related ties of managers who are member of organizational networks representing two different ideologies (religious and secular) in Turkey. In this research, the emergence of secular and devout entrepreneurs is considered as a phenomenon, and special attention is paid to religious transformation and secularism in Turkey. Social network analysis method is used to define the nature of communication links among 80 chairmen who are the members of two conflicting and dominant groups in Turkish business system. The findings show that Protestant work ethic suggested by Weber with regard to Christianity have attained a similar place over the past decade in Islamic organizational networks. The concern of political power in religion leads to organizational networks being nourished by religious norms and creeds in many developing countries. Especially in societies like Turkey where the state is dominant in the business life, organizations and managers prefer to be included in religious networks to make close contacts with the state. Another significant finding is that efforts of the members of religious networks-in spite of their relatively closed characteristics-in terms of being at the center of a network and taking the brokerage role, are highly developed on the contrary to the literature.

    Content-Based Search on Time-Series Microarray Databases Using Cluster-Based Fingerprints
    (2017) Ozkoc, Esma Erguner; Ogul, Hasan; AAG-1506-2021
    Background: The rapid growth of gene expression databases has created a need for content-based searches as an alternative to unstructured database queries using keyword- or metadata-based searches. Content-based searching is the ability to retrieve all experiments with similar gene expression patterns in a database regardless of the biological annotations provided for these experiments. Objective: While this concept is still in its infancy in a general context, in this study we focus on applying it to a specific subset of gene expression datasets, by only querying experiments involving time-series expression profiles. Method: To this end, we propose a novel experiment fingerprinting scheme obtained by clustering expression profiles, for content-based searching of time-series microarray experiments. To determine the retrieval ability of the proposed scheme, we performed a simulated information retrieval task on a large set of microarray experiments gathered from a public repository. The relevance between any two experiments was then defined using their commonalities based on annotated disease associations. Results and Conclusion: The results showed that relevant experiments can be more successfully retrieved using this new method compared with traditional differential expression-based methods.

    Deviant Employee Behavior in the Eyes of Colleagues: The Role of Organizational Support and Self-Efficacy
    (2017) Tuzun, Ipek Kalemci; Cetin, Fatih; Basim, H. Nejat; 0000-0001-6979-2040; 0000-0002-2487-9553; 0000-0002-2605-9962; ABB-5350-2020; J-8116-2015
    The present study investigates the influences of multifocal organizational support in the context of deviant employee behavior by examining the potential associations with employees' self-efficacy characteristics. The study proposes that perceived multifocal support and self-efficacy have a direct relationship with deviant behavior, and that these two variables interact in their relationship with deviant workplace behavior. Using self- and peer-reported data from 225 academics, hypothesized relationships were investigated using structural equation modeling. The results indicate that two different forms of support (organizational and supervisory) strongly influenced two different forms of deviant behavior (organizational and interpersonal). Whereas perceived organizational support decreases organizationally relevant deviant behavior, supervisory support decreases deviant behavior toward colleagues. The results also showed that high self-efficacy moderates both the negative relationship between organizational support and deviant behavior toward the organization and that between supervisory support and deviant behavior toward colleagues. The study also discusses the implications of these findings for managers, along with recommendations for future research.

    An Integrated Research for Architecture-Based Energy Management in Sustainable Airports
    (2017) Uysal, Murat Pasa; Sogut, M. Ziya; 0000-0002-8349-9403; 0000-0002-9782-7885; GQQ-0222-2022; T-2601-2017
    Energy Management (EM) has become crucial and much more complicated for airports with the introduction of various energy sources, technologies and different comfort requirements. Regarding the aviation industry as one of the major sources of global warming and air pollution, this situation becomes highly critical. However, the review of literature on Energy Management Information Systems (EMIS) for airports shows that the proposed solutions are usually domain-specific, platform-depended and away from suggesting complete solutions and architectures. Therefore, the main argument of this study is that a holistic and integrated approach should be adopted for EM in airports and we claim the notion of sustainability through the use of Enterprise Architecture (EA)-based EM. In this paper, we present the results of a two-faced research study. Action Research (AR) and Design Science Research (DSR) methods are combined to adopt an integrated approach. At the first phase, an EA is developed and evaluated, and then, this is followed by the second phase with three cases to find the potential energy savings in Istanbul Airport. Along with the findings, the primary and secondary contributions of this research brought to the EM knowledge domain are presented. Consequently, there is an important potential for energy saving in the terminal buildings, which would be approximately 70% of the total airport energy consumption. There is also a nearly 250.000 $/year potential saving, and also 121397 $/year for the daylight time and period. This research can be seen as an initial attempt to the enhancement of sustainable airports, and therefore, it has showed the potential for using EAs as a means to improve EM in airports. We hope that this study may help researchers to obtain an overview of existing and possible approaches to sustainability through the use of EAs for EM practices. (C) 2017 Elsevier Ltd.

    Patterns of Female Entrepreneurial Activities in Turkey
    (2017) Tuzun, Ipek Kalemci; Takay, Bahar Araz; 0000-0001-6979-2040; ABB-5350-2020; AAC-8845-2021
    Purpose - This study aims to identify and understand the challenges, motivational factors and future needs of female entrepreneurs in Ankara, Turkey. Design/methodology/approach - The study uses the qualitative analysis methodology and uses the qualitative data analysis software, MAXQDA 11. A total of 41 randomly selected female entrepreneurs from the city of Ankara and rural areas of the Ankara region participated in semi-structured in-depth interviews. A total of 284 codes were defined. Findings - Results indicate that female entrepreneurs are mostly intrinsically motivated and are driven by the desire to achieve and to become independent. The socially constructed role of women in Turkey is the primary challenge faced by female entrepreneurs in both urban and rural areas. Moreover, the major future needs identified for female entrepreneurs are support from public institutions and access to managerial consultants. Originality/value - There are limited number of studies that closely examine the characteristics of female entrepreneurship activity and their challenges/motivations in Turkey. This research contributes to the existing literature through its qualitative nature and by highlighting differences in urban and rural female entrepreneurs. Moreover, the results of this study are useful for policy makers to evaluate the future needs of female entrepreneurs and the programs that will be needed to overcome the challenges facing female entrepreneurs in the entrepreneurial process.

    An Analysis of The Carrying Capacity And Life Process Risks of UK and Turkish Insurance Intermediaries
    (2018) Kirkbesoglu, Erdem; Hood, John; https://orcid.org/0000-0002-6781-9753; ABI-3973-2020
    The primary aim of this paper is to examine the strategic risks associated with environmental selection and how this affects the life process risks of insurance intermediaries. To achieve this aim; firstly the carrying capacity of UK and Turkish insurance intermediaries is calculated and, secondly, the demographic, ecological and environmental variables that affect that carrying capacity are examined. Our study provides two contributions to the literature. For the first time, carrying capacity analysis is applied for an organisational community. As much as previous studies assume the existence of carrying capacity as theoretical, it has not been previously calculated on a quantitative basis. The second contribution is related to risk and insurance literature, specifically the life process risks of insurance intermediaries. The main rationale behind that analysis is the construction of a map that will simplify the strategic risk and reward decisions of insurers as to which areas are potentially profitable, or are indicative of fruitful relationships with intermediaries. Additionally, this research enables us to identify the areas that have potential for development in terms of insurance. For this reason, uncertainties relating to the selection of authorised brokers/agents as a strategic risk is, perhaps, minimised. Moreover, we have examined whether probable variables that can affect carrying capacity have contextual differences or not. The findings exhibit that there is contextual differentiations concerning the variables that affect the carrying capacity of both countries.

    Exchange Rate Risk and İnternational Trade: The Role of Third Country Effect
    (2018) Tunc, Cengiz; Solakoglu, M. Nihat; Babuscu, Senol; Hazar, Adalet
    Using the recently launched Exporter Dynamics Database of the World Bank, this paper empirically investigates the role of external exchange rate risk (third-country effect) on trade flows between countries. We find a strong positive influence of external exchange rate risk on exports to a specific destination. However, the effect is more observable in advanced destination countries, countries with low bilateral exchange rate volatility in comparison to external exchange rate volatility, and countries in which export is concentrated among a small number of firms.

    Patient Perceptions and Clinical Efficacy of Labial Frenectomies Using Diode Laser Versus Conventional Techniques
    (2018) Uraz, A.; Cetiner, F. D.; Cula, S.; Guler, B.; Oztoprak, S.; 29410192
    Introduction: The aim of present study was to compare the keratinized gingival tissue measurements, degree of subjective complaints and functional complications of using an 980 nm diode laser versus a scalpel for labial frenectomies. Material and methods: Thirty-six patients requiring labial frenectomies, between 14 and 51 years old, were randomly assigned to either scalpel or diode laser treatments. The soft tissue measurements, including the keratinized gingiva width (KGW), attached gingiva width (AGW) and attached gingiva thickness (AGT), were recorded before surgery, immediately after, one week later and one, three and six months after surgery. In addition, the functional complications and the morbidity (level of pain, swelling and redness) were evaluated during the first postoperative week using a visual analog scale (VAS). Results: We determined statistically significant gains in the KGW, AGW and AGT after surgery in both groups; however, there was no significant difference between the study groups. The VAS scores indicated that the patients treated with a diode laser had less discomfort and functional complications compare with scalpel surgery. Discussion: The results described above show that diode laser surgery offers a safe, impressive alternative for labial frenectomies that are comfortable for the patients.

    Adventurous and Charismatic Spirits: Entrepreneurs of Veblen and Schumpeter
    (2018) Aydin, Derya Guler; Araz, Bahar; Ozer-Imer, Itir; AAC-8845-2021
    The aim of this study is to analyze the evolving role of the entrepreneur in the economic and institutional structure based on the analyses of Veblen and Schumpeter. In both analyses, the historical evolution of the entrepreneur is crucial in understanding economic and institutional change. It can be claimed that clues for socio-economic transformation should be searched within institutions, entrepreneurs and habits and by this way, it is possible to demonstrate the mutual interactions between economic and Social spheres.
