Comparing Software Development Life Cycle Models with Multi-criteria Decision Making Approach
(2024 10TH INTERNATIONAL CONFERENCE ON CONTROL, DECISION AND INFORMATION TECHNOLOGIES, 2024) Alkis-Bayhan, Nurcan; Ozmen, Esra; Karaman, Ersin
Various software development life cycle models are adopted in the software domain. The selection of appropriate models is the main concern of this research since many factors affect the selection of these models. Characteristics of models, their advantages and disadvantages, in which projects they will be used, and how important the characteristics of the models have been studied in numerous research. In the scope of this research, first, the most preferred software life cycle development models, their features, and the factors that affect their selection were determined. Second, the study aims to compare the influential factors in selecting these models to determine the critical factors and rank them according to their importance level. An Analytical Hierarchy Process study was adopted and performed to achieve this comparison. Lastly, each software life cycle development model was compared to each other, and the important models were revealed in terms of each factor. According to the research results, the most critical factor in the model selection was "Project size."
Determinants of Unmet Need For Family Planning: Evidence From The 2018 Turkey Demographic and Health Survey
(JOURNAL OF BIOSOCIAL SCIENCE, 2024) Okem, Zeynep Guldem; Pekkurnaz, Didem
Unmet need for family planning is a valuable concept to indicate the discrepancy between women's fertility preferences and contraceptive use. Unmet need may lead to unintended pregnancies and unsafe abortions. These may result in health deterioration and reduced employment opportunities for women. The 2018 Turkey Demographic and Health Survey report indicated that the estimated unmet need for family planning doubled from 2013 to 2018, returning to the high levels of the late 1990s. Considering this unfavourable change, this study aims to investigate the determinants of unmet need for family planning among married women of reproductive age in Turkey by using the 2018 Turkey Demographic and Health Survey data. Logit model estimations revealed that women who were at older ages, more educated, wealthier, and had more than one child were less likely to have unmet need for family planning. Employment statuses of women and their spouses and place of residence were significantly associated with unmet need. Results emphasised that training and counselling to enhance the use of family planning methods should effectively target young, less educated, and poor women.
Dissident Women's Organizations as A Counter-Hegemonic Actor in Turkey
(TURKISH STUDIES, 2024) Gunduz, Melisa; Gencoglu, Funda
Could the Turkish women's movement, which has a strong reaction mechanism, be a constituent actor of counter-hegemony? The main reasons behind this question are the women's movement's deep-rooted history and its openness to combine theory with practice/action. When looked from the Chantal Mouffe and Ernesto Laclau's perspective of radical democracy theory, the women's movement appears to have a considerable potential of deciphering the existing hegemony and articulating the social demands which exclude and are excluded by the present-day hegemony in Turkey. This article tries to understand how women's movement in Turkey conceptualizes the existing power relations that constitute the neoliberal religio-conservative hegemony and how it responds to it.
Effect of Festival Satisfaction on Destination Loyalty through Destination Overall Image: The Case of Alaçatı Herb Festival
(ISTANBUL BUSINESS RESEARCH, 2024-12) Ozkan, Ayse Arslan; Yildiz, Erkan
This study examines the relationships among festival success factors, festival satisfaction, destination image and destination loyalty. Based on the literature review, festival success factors were identified and a model was developed to measure the direct impact of these factors on destination loyalty and the impact of these factors through the overall image of the destination. Data were collected during the 11th Ala & ccedil;at & imath; Herb Festival held between March 24-27, 2022. The data obtained were analyzed with the structural equation modeling. According to the results of the study, the program, festival area, staff, souvenirs, and information dimensions of festival success factors affect festival satisfaction. The effects of convenience and food dimensions on festival satisfaction were statistically insignificant. The festival satisfaction and destination overall image variables have positive effects on destination loyalty, and the festival satisfaction variable has positive effects on the destination overall image. The destination overall images an integral partial mediating role in the relationship between festival satisfaction and destination loyalty.
Evaluating Efficiency of Cloud Service Providers in Era of Digital Technologies
(ANNALS OF OPERATIONS RESEARCH, 2024) Azadi, Majid; Toloo, Mehdi; Ramezani, Fahimeh; Saen, Reza Farzipoor; Hussain, Farookh Khadeer; Farnoudkia, Hajar
The rapid growth of advanced technologies such as cloud computing in the Industry 4.0 era has provided numerous advantages. Cloud computing is one of the most significant technologies of Industry 4.0 for sustainable development. Numerous providers have developed various new services, which have become a crucial ingredient of information systems in many organizations. One of the challenges for cloud computing customers is evaluating potential providers. To date, considerable research has been undertaken to solve the problem of evaluating the efficiency of cloud service providers (CSPs). However, no study addresses the efficiency of providers in the context of an entire supply chain, where multiple services interact to achieve a business objective or goal. Data envelopment analysis (DEA) is a powerful method for efficiency measurement problems. However, the current models ignore undesirable outputs, integer-valued, and stochastic data which can lead to inaccurate results. As such, the primary objective of this paper is to design a decision support system that accurately evaluates the efficiency of multiple CSPs in a supply chain. The current study incorporates undesirable outputs, integer-valued, and stochastic data in a network DEA model for the efficiency measurement of service providers. The results from a case study illustrate the applicability of our new system. The results also show how taking undesirable outputs, integer-valued, and stochastic data into account changes the efficiency of service providers. The system is also able to provide the optimal composition of CSPs to suit a customer's priorities and requirements.
Explaining The Relationship Between Person-Organization Fit And Entrepreneurial Intention Through Workplace Ostracism And Loneliness
(Başkent Üniversitesi İktisadi İdari Bilimler Fakültesi, 2024-03-10) Basar, Ufuk; Karamanlioglu, Almula Umay; Sigri, Unsal
PurposeThe entrepreneurial intention of employees refers to the motive of those who work in a company to resign and start their businesses instead of continuing to be wage earners. It is one of the under-studied aspects of entrepreneurship research. Accordingly, this research paper aimed to find out whether perceived person-organization fit was related to the entrepreneurial intentions of employees and whether perceived workplace ostracism and loneliness mediated this process.Design/methodology/approachA cross-sectional study was conducted to achieve the purpose. The data were collected through a questionnaire technique from a total of 572 employees. Participants were from 20 different provinces of Turkey and 27 different sectors. Hypotheses were tested through the structural equation modeling technique.FindingsFindings indicated that a lack of perceived person-organization fit resulted in entrepreneurial intention. Workplace ostracism resulted in workplace loneliness. Workplace ostracism and loneliness significantly mediated the relationship between perceived person-organization fit and entrepreneurial intention.Originality/valueTo the best of authors' knowledge, this study was the first to establish and test the relationships between person-organization fit, entrepreneurial intention, workplace ostracism and loneliness. In this regard, findings can benefit researchers and practitioners in better figuring out why some employees leave their companies to start their businesses while others do not.

(CURRENT PSYCHOLOGY, 2024) Kizrak, Meral; cinar, Esra; Aydin, Esra; Kemikkiran, Nurcan
Drawing on the Conservation of Resources (COR) theory and the social capital approach, this study aims at examining a serial mediation model to explore why employees intend to leave their organization by taking into consideration psychological safety, networking ability and relational job crafting. We tested our research hypotheses with the data obtained from 218 employees working in different sectors. The results revealed that (1) psychological safety is negatively associated with intention to leave, and (2) networking ability and relational job crafting serially mediate the link between psychological safety and intention to leave. This study presents crucial evidence for organizations to retain and engage employees by justifying the importance and effects of building social relationships in the workplace.

(ISRAEL AFFAIRS, 2024-01-02) Bilgin, Kivilcim Romya; Mercan, S. Sezgin; Ongun, Yelda; Gungor, F. Senem; Karadag, Haluk; Han, Ahmet K
Multidimensional relations have protected Turkey and Israel from the effects of political crises. The main question of this article is how Turkey-Israel relations impact Turkish Jews business representatives. Interviews with Turkish Jewish businesspeople, who are primarily influenced by the developments in foreign policy due to their international business volumes, answered the question of how Turkish Jews were influenced by foreign policy, and emphasised the importance of minorities in foreign policy issues. The article explores the role of minorities in foreign policy and sheds light on how ethnic minorities, who are viewed as secondary agents in foreign policy, are influenced by the Turkey-Israel relations.
Multifractal Detrended Cross-Correlations between Green Bonds and Commodity Markets: An Exploration of the Complex Connections between Green Finance and Commodities from the Econophysics Perspective
(FRACTAL AND FRACTIONAL, 2024-03-08) Acikgoz, Turker; Gokten, Soner; Soylu, Abdullah Bugra
Green bonds represent a compelling financial innovation that presents a financial perspective solution to address climate change and promote sustainable development. On the other hand, the recent process of financialisation of commodities disrupts the dynamics of the commodity market, increasing its correlation with financial markets and raising the risks associated with commodities. In this context, understanding the dynamics of the interconnectivity between green bonds and commodity markets is crucial for risk management and portfolio diversification. This study aims to reveal the multifractal cross-correlations between green bonds and commodities by employing methods from statistical physics. We apply multifractal detrended cross-correlation analysis (MFDCCA) to both return and volatility series, demonstrating that green bonds and commodities exhibit multifractal characteristics. The analysis reveals long-range power-law cross-correlations between these two markets. Specifically, volatility cross-correlations persist across various fluctuations, while return series display persistence in small fluctuations and antipersistence in large fluctuations. These findings carry significant practical implications for hedging and risk diversification purposes.
Preferences for Intuition and Deliberation in Decision-Making in the Public Sector: Cross-Cultural Comparison of China, Taiwan, the Philippines, and the USA
(Başkent Üniversitesi İktisadi İdari Bilimler Fakültesi, 2024-02-19) Svenson, Frithiof; Ermasova, Natalia; Cetin, Fatih; Launer, Markus A.
This paper explores hypotheses based on Hofstede's cultural framework showing that decision-makers' culture impacts their implicit choice. How people make decisions is tested through the behavioral dimension preference for intuition/preference for deliberation based on data from 1,233 employees in China, Taiwan, the Philippines, and the USA. This study reveals significant variation in individuals' intuitive and affective decision-making in the public sector across different countries. Individuals' deliberative decision-making is impacted by long-term orientation and uncertainty avoidance. The study finds that Eastern countries (China, the Philippines, and Taiwan) have higher scores for intuitive/affective decision making than the Western countries (the USA).

That allows financial institutions, including Fintechs, to use this information for taking precautions and proactive actions against shocks.Originality/value - This study is an initial attempt to explore the impacts of the Covid-19 on banks in an emerging economy by using BMC. With that, this study contributes to the literature by explaining the effect of progression of digitalization in banking from a strategic business model perspective using a qualitative research method.
The İmpact Of Fluctuating İnternational Fertiliser Prices And Exchange Rates On Domestic Fertiliser Prices İn Türkiye
(AGRICULTURAL ECONOMICS-ZEMEDELSKA EKONOMIKA, 2024-12-14) Bor, Ozgur; Dagistan, Nihat
This study aims to examine the relationship between domestic and international prices of di -ammonium phosphate (DAP) and urea fertilisers together with exchange rates in Tiirkiye using the non-linear autoregressive distributed lag (NARDL) model on monthly data for the period of January 2011 to September 2022. The result of the study provides empirical evidence about the presence of asymmetries in the short and long -run among these fertilisers. The findings of the study confirm that international prices of di -ammonium phosphate and urea fertilisers have a symmetric effect in the long -run and exchange rate of the Turkish lira to US dollars has an asymmetric effect on the domestic prices of fertilisers in the short run. This is the first study in Tiirkiye to delineate the dynamic simultaneous interaction among these markets and its findings can be extremely useful for academicians, and policymakers to make decisions regarding the market structure of countries that do not have sufficient domestic resources for fertiliser supply and are dependent on imports.
The Impact Of High-Performance Human Resource Practices On Subjective Career Success: The Mediating Role Of Psychological Capital And Organizational Commitment
(JOURNAL OF EAST EUROPEAN MANAGEMENT STUDIES, 2024-06-19) Toyata, Berk; Kizrak, Meral; Cakar, Mehmet
Utilizing insights from positive psychology, social exchange theory, and social cognitive career theory, this study aims to investigate the mediating role of psychological capital and organizational commitment in the relationship between high-performance human resource (HR) practices and subjective career success. Data were collected from a sample of 429 private sector employees working on European Union projects in Turkey. Hypotheses were tested using regression, correlation, and mediation analyses, as well as Sobel test statistics. Results indicate that high-performance HR practices, organizational commitment, and psychological capital positively influence subjective career success. Additionally, there is evidence that, unlike organizational commitment, psychological capital mediates the relationship between high-performance HR practices and subjective career success. Our study underscores the need for organizations to foster and develop psychological capital among their employees to maximize the effectiveness of HR practices in promoting subjective career success.

The Mediating Effect Of Psychological Safety On The Relationship Between Authentic Leadership And Turnover Intention
(MIDDLE EAST JOURNAL OF MANAGEMENT, 2024-07-20) Durukan, Mehmet Hakan; Kibaroglu, Gamze Guner; Basim, H. Nejat
This study was conducted to examine the role of psychological safety in the effect of authentic leadership on turnover intention. In this framework, from the perspective of leader-member interaction theory, it has been shown that an authentic leader can reduce turnover intention. Within the scope of the study, data were collected from 340 participants by survey method and analysed. According to the results of the research, there is an inverse and significant relationship between authentic leadership and turnover intention. In addition, while authentic leadership affects psychological safety in the same direction, psychological safety negatively affects turnover intention. In addition to these results, the most important result of our study is that psychological safety plays a mediating role in the effect of authentic leadership on turnover intention. The results of the study showed that creating a transparent work environment based on authentic leadership and establishing basic psychological safety can reduce individual turnover intention.
The Moderating Role Of Paternalistic Leadership In The Relationship Between Job Satisfaction And Job Stress Among Health Workers In Gaziantep, Turkey
(WORK-A JOURNAL OF PREVENTION ASSESSMENT & REHABILITATION, 2024-12-09) Tunc, Ahmet; Yagar, Sema Dokme; Gercek, Emine; Yagar, Fedayi
BACKGROUND: Adopting an effective leadership style is of critical importance in increasing healthcare efficiency and therefore determining patient satisfaction. For example, although there are many new and effective leadership types today, the paternalistic leadership approach can still play an effective role in developing countries. OBJECTIVE: The aim of this study is to examine the moderating role of paternalistic leadership in the relationship between job satisfaction and job stress. METHODS: A total of 466 healthcare workers completed measures of perceived paternalistic leadership, job stress, and job satisfaction. The research was conducted in the center of Gaziantep, one of the largest cities in Turkey. Regression analysis was used to evaluate the moderate variable. Dawson slope were used to visualize the results. RESULTS: A negative relationship was found between job satisfaction and job stress. Additionally, it has been determined that the perception of paternalistic leadership has a moderating role. It has been observed that as the perception of paternalistic leadership increases, the negative relationship between job satisfaction and job stress decreases. CONCLUSION: It has been concluded that the paternalistic leadership approach can play a critical role in increasing the productivity of healthcare workers and reducing the negative effect of stress on satisfaction. It has been suggested that policies be developed to develop appropriate strategies for creating work environments that will increase employees' perceptions of paternalistic leadership.
The Retreat From Bıst: Insıghts Into Foreıgn Portfolıo Investment Movements
(EKONOMI POLITIKA & FINANS ARASTIRMALARI DERGISI, 2024-11-15) Alp, oezge S. E. Z. G. I. N.; Hazar, Adalet; Babuscu, Senol
The need for rapid growth and development in developing countries increases the demand for capital. As a result, foreign portfolio investments are of great importance, especially in emerging markets, as they help meet capital needs. However, their ability to move quickly also introduces high volatility to financial markets. This study examines changes in the share of foreign portfolio investors in Borsa Istanbul from 2004 to 2023, aiming to provide long-term insights to market participants. Initially, changes in the foreign portfolio investor ratio over time are graphically analyzed alongside the BIST 100 index and the average interest rate of deposits with a maturity of up to 3 months. These changes are evaluated in the context of both global and local developments. The study then investigates the causal relationship between the foreign portfolio investor ratio and the BIST 100 index using a cointegration test and a causality test based on the VECM model. The findings show a one-way causality from the BIST 100 index to the foreign portfolio investor ratio, indicating that foreign investors' market movements are largely influenced by the performance of the BIST 100, and local market dynamics significantly affect foreign capital inflows.
Understanding Cypriot Youth Views On Peace: Bottom-up Experiences of Everyday Peace
(SOUTHEAST EUROPEAN AND BLACK SEA STUDIES, 2024) Dizdaroglu, Cihan
outh views and their engagement within practices of everyday peace(building) are paramount to fostering peace, despite the deadlocks at the elite level negotiations. This article provides a bottom-up approach that recognizes the agency and potency of youth in 'everyday peace' by providing a voice to marginalized Cypriot youth. The semi-structured interview findings highlight that the views that Cypriot youth harbour on peace diverge from elite views and focus on societal and practical needs. Accordingly, Cypriot youth's understanding of peace converges around three interrelated main themes - social cohesion, no discrimination and hatred, and unrestricted freedom of movement - based on frequency in expansive series of youth interviews. This article argues that youth's priorities and responses bespeak their meaningful contributions to peace through their everyday actions.
