Publication Metadata only Agent-Based Modelling of Interstellar Contacts Using Rumour Spread Models(Cambridge University Press, 2020) Uyar, Tevfik; Özel, Mehmet EminSome stochastic model of rumours asserts that even an advanced communication network does not guarantee every agent hears certain news because they predict that rumour spreaders convert to stifflers when contacted with an informed agent. In this study, we adapted two rumour spread models to interstellar communication by developing an agent-based model (ABM) for exploring the issue more rigorously. We enhanced the spread models by adding two additional parameters called conversion probability and stop-criterion, which represent the eagerness and persistency of civilizations to establish new contacts. Results of the ABM under several settings suggest that limited SETI searches lead to undiscovered civilizations. Earth may be one of these undiscovered civilizations although an advanced communication network might already be set up. Hence, we speculate that rumour spread models can propose another solution to Fermi's Paradox.Publication Open Access Are Time Management and Cyberloafing Related? Investigating Employees’ Attitudes(2020) Ötken, A. Begüm; Bayram, Ayhan; Göl Beşer, Senem; KAYA, ÇİĞDEM; 246912; 108211; 18140Time is a critical commodity both for individuals and companies because it is not possible to substitute or purchase it. The concept of time management, therefore, attracted the attention of both academicians and practitioners. Companies started to question behaviour of employees using their companies’ Internet access for non-work-related purposes during work hours. These activities constitute an unproductive use of time and detract employees from completing their work demands. In this framework, the purpose of this study is to understand whether time management and cyberloafing are related. Data were collected from 300 employees working in Istanbul, Turkey. Results show that the time wasters dimension negatively explained the variance in serious cyberloafing. Results also show that time planning and time attitude dimensions positively explained the variance in minor cyberloafing. Understanding the relationship between time management and cyberloafing provides fruitful results for companies and individuals in terms of productivity and achieving goals at work.Publication Open Access Bibliometric Analysis of Paternalistic Leadership(Hacı Mustaf Paksoy, 2024) DEVECİYAN, MERİ TAKSİThe study presents a bibliometric analysis of 520 publications found through a Web of Science database search to identify trends and developments in the academic literature on paternalistic leadership. It is also expected that the study will identify existing gaps in the “paternalistic leadership” literature, where the frequency of study tends to increase after 2018, and potential opportunities for future research. As a result of the analysis, it was determined that the highest number of citations in the publications reached in the field of paternalistic leadership was in 2022, and the most frequently used keywords were “paternalistic leadership” and “authoritarian leadership”. In addition, it was determined that the country that conducted the most studies and had the highest citation score was Peoples R China. According to the findings of the analysis, it was concluded that Cheng Bs is the researcher with the highest number of publications and citations in this field. The study is expected to contribute by raising awareness for researchers who want to study leadership literature in the field of management.Publication Open Access Bibliometric Analysis of The Concept of "Organizational Differences" Using Visual Mapping Technique(ADAMOR, Toplum Araştırmaları Merkezi, 2024) DEVECİYAN, MERİ TAKSİIn this study, it is aimed to perform a bibliometric analysis of the research related to the concept of organizational differences and to make inferences about the general structure of the field. In this direction, in the research, 303 scientific publications on "organizational differences" were examined with the bibliometric analysis method using the Web of Science database, and then the obtained data were visualized using the VOSviewer software program. Bibliometric methods such as keyword analysis, citation analysis, co-author analysis, co-citation analysis of authors were used on the identified scientific publications. Using bibliometric methods, a comprehensive view of the dynamics of the field is presented; the development of the literature on the concept of "organizational differences" has been mapped by determining the basic studies, types, years, authors, countries and publication areas. As a result of the study, it was found that the subject of "organizational differences" was not studied sufficiently in the literature; the most publications on a country basis were from America, the most publications on a year basis were published in 2019, and the most commonly cited author was Alstemark B. It is thought that the findings obtained as a result of the analysis will provide resources for future studies on "organizational differences".Publication Open Access Economic Growth: Is it Green or not? An Application on OECD(2021) Akarsu, Gülsüm; GÜMÜŞOĞLU, NEBİLE KORUCU; 53145; 115505For climate change mitigation and considering other environmental impacts of traditional energy sources, countries have started to implement energy policies in favor of renewable energy sources. In this way, without any detrimental effect on economic growth, countries can decrease their fossil fuel consumption. However, there is a debate about the direction of causality between renewable energy consumption and economic growth as for the total energy-growth nexus. Moreover, in the literature, the studies focus only on the total or specific type of renewable energy consumption while analyzing the direction of causality. From this point of view, there is a gap in the literature in such a way that there is a need for a comprehensive analysis which compares the existence and direction of causality for different types of renewable energy sources and technologies. Therefore, the main aim of this study is to investigate renewable energy consumption and growth nexus. By using panel data on renewable electricity generation for OECD countries over the years from 2000 to 2016, the causality is tested for different technologies. Moreover, as the economic growth may not correctly measure the overall economic well-being, another measure for welfare is used. Therefore, the main motivation of this study is to include welfare in renewable energy and growth nexus in which different type of technologies for renewable energy are considered. The results for both economic growth and welfare measure show that the existence and directi highly differs among the different technologies. Therefore, technology specific policies should be implemented in order to stimulate the renewable energy investments and consumption.Publication Metadata only The Effects of the Developments in Artificial Intelligence and Open-Access Software on the Visions of Academicians(Brill Academic Publishers, 2024) BATAKLAR, SİNAN; DEVECİYAN, MERİ TAKSİThis research aims to examine the effects of developments in Artificial Intelligence (AI) and open-access software on the visions of academicians. The research was conducted using the phenomenology pattern, one of the qualitative research methods, and semi-structured in-depth interviews were preferred during the data collection process. Descriptive and coding-based qualitative content analysis methods were used in the research process. Emerging themes include the use of artificial intelligence in higher education; situation analysis of the use of AI in academics (SWOT); and strategic dimension of using AI in higher education. These themes explain in detail the potential effects of AI and open-access software on the strategy and competitiveness dimensions of academics’ visions. It is expected that the study will make significant contributions to understanding the changes that AI and open-access software will create in the academic world and how these technologies can be integrated into the way academics work.Publication Open Access Ethical Leadership, Organizational Culture, and Intrapreneurship: A Study in the Banking Sector(Nişantaşı Üniversitesi, 2024) DEVECİYAN, MERİ TAKSİThe purpose of this research is to measure the perceptions of bank sector employees regarding ethical leadership, intrapreneurship, and organizational culture, and to examine the relationship between these variables. The cross-sectional survey method was utilized for data collection and analysis, employing quantitative research methods. For this purpose, data collected through surveys from 395 bank personnel using convenience sampling method were evaluated through statistical analyses. The findings indicate a significant positive relationship among bank employees between ethical leadership, organizational culture, and intrapreneurial behavior. It was found that organizational culture has a higher explanatory power for intrapreneurship than the perception of ethical leadership, while ethical leadership has a higher explanatory power for organizational culture. This study provides a significant contribution to understanding the dynamic relationship between ethical leadership, intrapreneurship, and organizational culture. This understanding can guide managers and researchers in leadership strategies and organizational culture development practices. The rarity and significance of this study are underscored by the lack of previous research simultaneously addressing the relationship between ethical leadership, intrapreneurship, and organizational culture in the banking sector, thus indicating its potential to contribute to the academic literature in this field.Publication Open Access The Impact of Green Business Ethics and Green Financing on Sustainable Business Performance of Industries in Türkiye: The Mediating Role of Corporate Social Responsibility(MDPI, 2024) Alay, Hazal Koray; Keskin, Abdulkadir; Şen, Gülaçtı; Kayalıdereden, Didem; Berber, Şayan; DEVECİYAN, MERİ TAKSİThe purpose of this research is to understand the relationship between green business ethics, green finance, and sustainable business performance, and to evaluate the role of corporate social responsibility (CSR) in this relationship. The impact of the damage inflicted on nature's functioning order is being felt much more strongly today. In light of these realities, companies must emphasize sustainability principles not just out of financial concerns but as a result of corporate social responsibility. In this context, focusing on the role of corporate social responsibility in sustainable business performance is the main goal of this research. Quantitative research methods, specifically the cross-sectional survey method, were employed for data collection and analysis. For this purpose, a convenience sampling method was used to select 427 white-collar employees working in industries operating in T & uuml;rkiye as the sample for this study. The data collected through surveys were analyzed using the AMOS 24 statistical program. The findings underscore that green business ethics and green finance have a significant impact on corporate social responsibility and sustainable business performance. Additionally, it was determined that corporate social responsibility plays an intermediary role in shaping sustainable business performance. These findings are expected to provide an important foundation that can guide both employees and managers in developing awareness about green policies and sustainability, emphasizing the importance of green policies in working life.Publication Restricted A Novel Multistage CAD System for Breast Cancer Diagnosis(Springer London Ltd., 2023) Karacan, Kübra; UYAR, TEVFİK; Tunga, Burcu; Tunga, M. AlperComputer-aided diagnosis (CAD) systems are widely used to diagnose breast cancer using mammography screening. In this research, we proposed a new multistage CAD system based on image decomposition with High-Dimensional Model Representation (HDMR) which is a divide-and-conquer algorithm. We used digital mammograms from Digital Database for Screening Mammography as dataset. We neglected BIRADS classification and used a brand-new clustering based on HDMR constant and breast size. To find the best performance of HDMR-based CAD system, we compared different pre-processing settings such as contrast enhancement with CLAHE and HDMR, feature extraction with HDMR, feature scaling, dimension reduction with Linear Discriminant Analysis. We used several Machine Learning algorithms and measured the performance of proposed system for normal-benign-malign classification, cancer detection, mass detection and found that the proposed system achieves 66%, 71% and 87% accuracy, respectively. We were able to achieve 92% accuracy, 100% sensitivity and 91% specificity in specific clusters. These results are comparable with deep learning-based methods although we simplified the pipeline and used brand-new HDMR-based processes.Publication Open Access Perceptions and Expectations of International and Ethnically Diverse Students in the Context of Diversity Management Policy Document in a Turkish Foundation University(Türk Kooperatifçilik Kurumu, 2023) Bataklar, Sinan; DEVECİYAN, MERİ TAKSİThe aim of this study is to analyse the effects of having policy documents regarding diversity management on students’ perceptions in higher education context. The study was carried out with 25 international students and students with different ethnic backgrounds who have been studying in various undergraduate and associate degree programs of a Turkish foundation university. The data were gathered via open-ended questions and phenomenology method. The data were applied using the qualitative content analysis approach. Based on the analysis of the data, noticeable themes have been reached regarding the students’ perceptions of the university’s diversity management policies and the academic satisfaction they get in the provided learning atmosphere during their time on and off campus. The themes and their sub-themes are as follows: The theme “the presence of the university to provide an inclusive educational atmosphere in the availability of students from different countries and ethnic backgrounds” include the significance of policy documents of the higher education institution, the necessity of an international campus and awareness raising and networking events, the theme “expectations to increase satisfaction about academic processes” includes the sub-themes of academic material support, learn by doing (allocation of more time for internship), more interaction with the academic staff, qualifications of the academic staff and sensitivity to individual learner types and learner backgrounds, the theme “expectations to create an international campus with a successful diversity management among students” includes attracting more students from different regions of the world, communication frameworks among students and graduates, high frequency of extra-curricular activities.Publication Open Access Social Networks in the Jewelry Industry: A Qualitative Research on Ethnic/Minority Entrepreneurs in Turki̇ye(Beykoz Üniversitesi, 2024) Arıkboğa, Fatma Şebnem; DEVECİYAN, MERİ TAKSİThe study aims to reveal how minority entrepreneurs benefit from social networks and the role of social networks in the jewelry sector, which is considered one of the sectors where the use of social networks can be easily detected, where ethnic and minority entrepreneurs are clustered in Istanbul province, in Türkiye. In this context, phenomenology design was used as a qualitative research method, and the research data was collected through individual face-to-face in-depth interviews with a pre-prepared semi-structured questionnaire with 24 minority entrepreneurs registered with the Istanbul Chamber of Jewelers (IKO) and the Istanbul Chamber of Commerce Jewelry Committee (ITO). Descriptive and coding-based qualitative content analysis was used to analyze the data. MAXQDA qualitative data analysis program was used to visualize the data. As a result of the study, minority entrepreneurs in the jewelry sector benefit heavily from their social networks (especially their co-ethnic group) to access resources. Within the framework of the unique structure of the jewelry sector and the internal dynamics of minorities, the impact of the concept of "master" on the social networks of entrepreneurs in addition to family friends, who are among their strong and close networks, was also observed. The study is expected to contribute to the field by offering suggestions, as it is the only study that addresses the concept of "master" in the sectors of the creative industries and brings the concept to the literature.Publication Restricted Stress Management and Psychological Resilience of Healthcare Workers: The Role of Job Satisfaction, Job Performance, and Continuance Commitment(SIPISS- Edizioni FS Publishers, 2024) Alay, Hazal Koray; Ozturk, Emine; DEVECİYAN, MERİ TAKSİIntroduction: The purpose of this study is to examine the role of job satisfaction, job performanceand continuance commitment in the relationship between psychological resilience and stresmanagement among healthcare workers at İstanbul province public hospitals, in Turkey.

Employment in the information and communication technology (ICT) sector is widely known for being male-dominated, and recently women’s participation has become an important subject. This chapter aims to examine women’s employment in Turkey’s ICT sector from 2009 to 2016, from a social inclusion perspective, by using various indicators. Comparisons with European Union (EU) countries provide perspective on tracking the progress of employment structure and education choices for ICT by gender. All indicators signify the existence of a gender gap resulting in low rates of inclusion of women in Turkey’s ICT employment during the period. Examination of the reasons leads to making some policy recommendations to promote social inclusion of women in Turkey’s ICT employment. © 2022 by IGI Global. All rights reserved.
