Item Factors Determining Consumer Concerns About Clothing Industry Problems(2023) Erol boyaci, Gulay; Senturk ozer, Leyla; HOC-6390-2023Although the public concern towards unsustainable current production and consumption is growing, the inadequacy of global regulations on sustainability issues puts the responsibility on consumers. However, despite their concerns, some consumers need help shopping from sustainable brands. The current research examines some antecedents of consumer concern towards the clothing industry's environmental and sweatshop issues. Data is obtained from 372 Turkish fast fashion consumers through online platforms. Level of exposure to informative posts on social media platforms, the perceived knowledge and belief towards the issues positively affect concern. Also, decreasing concern towards these problems with advancing age is observed in Turkiye.Item Women Board Members' Impact on ESG Disclosure with Environment and Social Dimensions: Evidence from The European Banking Sector(2023) Gurol, Burcu; Lagasio, Valentina; https://orcid.org/0000-0001-9974-2351; HGC-2474-2022PurposeThis study aims to investigate the relationship between banks' board structure and sustainability performance. Design/methodology/approachThe empirical quantitative paper covers a sample of 35 European banks that are listed at the EUROSTOXX 600. Regression analysis techniques were used in the analyses. FindingsResults indicate that board size, women ratio and independent directors ratio on board are positively and significantly related to environmental social governance (ESG), E and S disclosure scores. Also, we find that ESG disclosure is related to bank profitability. Practical implicationsFindings have implications for both policymakers and practitioners (bankers and investors). Large bank boards, which have women and independent members, could perform better in terms of ESG disclosure. The results also show that large banks and banks with high borrowing care more about sustainability. For banks to reach resources, they should perform well in terms of sustainability disclosure to their stakeholders. Social implicationsBanks should observe academic findings on corporate governance (CG) practices, which lead to a better ESG disclosure to structure their CG to improve at the best their disclosure policies: they should prefer larger boards with a high level of women and independence. In addition, we attach importance to the ESG performance of the banking sector due to its fund transfer functions. Banks transfer the deposits they collect to those in need of funds as loans. For this reason, it is important to which sector and which business they give credit. The importance of banks on ESG and their adoption of sustainability dimensions also affect their credit decisions. Originality/valueThis study examines the relationship between banks' board structure variables and their effect on ESG, E and S scores separately. This study thinks that the G score can be a handicap for ESG-CG relations. Because chosen CG variables (women ratio, independent ratio, board size) affect G scores positively and can reason for positive ESG-CG relation. The environmental and social impact of women ratio, independent ratio and board size can be seen in this study.Item Bibliometric Profiles of Studies on Organization Theory in Turkey: Periodic Comparison of Cite Networks(2015) Kirkbesoglu, Erdem; Sozen, H. Cenk; Kurt, Esra; 0000-0002-6781-9753; ABI-3973-2020The purpose of this study is to determine relational links via documents and to have an impression about the development of organization theory in Turkey by using bibliometric methods. Studies of various researchers have been considered with a longditutional approach.The papers which had been presented in National Management and Organization Congress within 10 years were examined in terms of most cited theories, authors, research topics and academic journals. The data were also used for social network analyses to examine interactions between universities, research topics and authors.The data were examined under two periods consist of five years. Findings show that there is a variation between two periods and work style have been transferred to newly founded universities or PhD programs in these universities.Item The Paradox Between Institutional Logics in Organizational Fields: The Case of Turkish Military Service Field(2015) Kalemci, Rabia Arzu; Gokoglu, Mustafa Mehmet; Tuzun, Ipek Kalemci; 0000-0002-2617-2666; 0000-0001-6979-2040; ABC-2318-2020; ABB-5350-2020Turkish military services field can be conceptualized for embracing two distinct and inconsistent types of institutional logics, namely; mandatory military service logic as the dominant and pragmatic logics as the alternatives. We examine the relationship between the dominant logic which determines legitimate organizational activities and alternative logics which are activated sporadically in the field of Turkish military services. From this standpoint, the circumstances whereby pragmatic logics as alternative institutional logics become effective in the field without devitalizing the dominant logic is explored. Broadly, the results indicate that dominant and alternative logics can support each other in order to preserve field's static condition, rather than interfere with each other so as to induce a permanent transformation.Item The Intellectual Structure of the Information Systems Field: Research Styles and Publication Patterns of North American and European Paradigms(2022) Ozkoc, Esma Erguner; Kefkir, Teoman Ahmet; Kirkbesoglu, Erdem; https://orcid.org/0000-0002-6781-9753; AAG-1506-2021; ABI-3973-2020This paper identifies the researches that have had the greatest impact on the Information Systems (IS) discipline and analyses the changes that have taken place in the intellectual structure of this discipline within the ongoing paradigmatic debates between Europe and North America. The methodology applies citation analysis and social network analysis to the articles published in four European and North American journals with the highest impact factors in the IS field. The findings of the study reveal a significant difference between the research styles and publication patterns of European and North American research traditions.Item Effect of Polynomial, Radial Basis, and Pearson VII Function Kernels in Support Vector Machine Algorithm for Classification of Crayfish(2022) Garabaghi, Farid Hassanbaki; Benzer, Recep; Benzer, Semra; Gunal, Aysel Caglan; 0000-0002-5339-0554; A-5050-2014Freshwater crayfish are one of the most important aquatic organisms that play a pivotal role in the aquatic food chain as well as serving as bioindicators for the aquatic ecosystem health assessment. Hemocytes, the blood cells of crustaceans, can be considered stress and health indicators in crayfish, and are used to evaluate the health response. Therefore, total hemocyte cell numbers (THCs) are useful parameters to show the health of crustaceans and serve as stress indicators to decide the quality of the habitat. Since, catching the fish and the other aquatic organisms, and collecting the data for further assessments are time-consuming and frustrating, today, scientists tend to use swift, more sophisticated, and more reliable methods for modeling the ecosystem stressors based on bioindicators. One tool which has attracted the attention of science communities in the last decades is machine learning algorithms that are reliable and accurate methods to solve classification and regression problems. In this study, a support vector machine is carried out as a machine learning algorithm to classify healthy and unhealthy crayfish based on physiological characteristics. To solve the non-linearity problem of the data by transporting data to high-dimensional space, different kernel functions including polynomial (PK), Pearson VII function-based universal (PUK), and radial basis function (RBF) kernels are used and their effect on the performance of the SVM model was evaluated. Both PK and PUK functions performed well in classifying the crayfish. RBF, however, had an adverse impact on the performance of the model. PUK kernel exhibited an outstanding performance (Accu-racy = 100%) for the classification of the healthy and unhealthy crayfish.Item Analysis of Personal Information Security Behavior and Awareness(2016) Ogutcu, Gizem; Tastik, Ozlem Muge; Chouseinoglou, Oumout; AAD-2902-2020Hardware 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.

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.Item Content-Based Search on Time-Series Microarray Databases Using Cluster-Based Fingerprints(2017) Ozkoc, Esma Erguner; Ogul, Hasan; AAG-1506-2021Background: 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.Item 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-8116-2015The 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.
