Leveraging explainable artificial intelligence in understanding public transportation usage rates for sustainable development
Public transportation usage prediction is valuable for the sustainable development of transportation systems, particularly in crowded megacities. Machine learning technologies are of great interest for predicting public transportation usage. While these technologies outperform many other techniques, they suffer from limited interpretability. Explainable artificial intelligence (XAI) tools and techniques that offer post -hoc explanations of the obtained predictions are gaining popularity. This paper proposes an advanced tree-based ensemble algorithm for public transportation usage rate prediction. We aim to explain the predictions both with the most widely used technique of XAI, Shapley additive explanation (SHAP) and in the light of the rules presented. To predict the total public transportation usage, the proposed model combines all types of public transportation, categorized as ferry, railway, and bus, unlike most existing studies focusing on a single kind of public transport. Besides the sort of transportation, the day of the week, whether the day is special, and the daily ratio of passenger types were identified as model features for predicting the daily usage of each type of public transportation. We tested the proposed model using an open data set from Izmir City, Turkey. While the model had superior prediction performance, the explanations showed that the type of public transportation, weekday, and the ratio of full-fare passengers have the highest SHAP values, and the model features have many interactions. We also validated our results using an online data set showing Google search trends.Management || Operations Research & Management Scienc
The Devil in the Mirror: Projections of Desire from Folk Tales to Witcher 3: The Wild Hunt
Dealing with the Devil is one of most prominent cultural motifs across the history of recorded folk tales. From ancient folk tales to contemporary cultural products, the Devil has appeared as an illicitly desirable being. The focal point of dealing with the Devil is that it is instigated by a pre-existent desire to exceed one's capacity determined by their temporal circumstances. In the Christian narrative tradition, a deal with the devil occurs over a Manichean undercurrent and ends in the condemnation of the participant or in the devil's humiliation. Pantheistic traditions discombobulate this contract by virtue of the nonexistence of Manichean binaries. This study aims to analyze the prevalence of desire in the deal with the devil motif throughout various tales and how the video game Witcher 3: The Wild Hunt (2015) complicates notions that are often taken for granted in Christian folk tales through its core narrative design.Cultural Studies || Communicatio
Building sustainable resilient supply chain in retail sector under disruption
Blockchain technologies have played a crucial role in transforming the retail industry, leading to remarkable advancements in recent times. Its pivotal role in managing risky environments by offering preventive and proactive measures cannot be overstated. The research contribution lies in introducing a set of criteria for assessing the adoption of Blockchain technology, specifically designed to evaluate the resilience of the retail sector. This study aims to ensure the establishment of a sustainable, resilient supply chain across diverse retail categories, particularly in the face of uncertain circumstances. A hybrid decision-making approach that combines the BestWorst Method (BWM) and Fuzzy TODIM has been employed to achieve these objectives. This study encompasses various types of retail companies to assess and compare their resilience levels by adopting Blockchain technology. The results of this study robustly suggest that speciality retailers with well-established, long-term partnerships are more predisposed to embrace and leverage the capabilities of Blockchain technologies. Conversely, discount retailers in Turkey face various challenges that impede their effective integration of Blockchain technologies. These challenges encompass collaborating with suppliers on short-term agreements and the unavailability of product tracking, among other factors. As a result, the outcomes of this study offer valuable insights for retailers in the sector, suggesting that they should consider modifying their operational strategies to better align with the adoption and integration of Blockchain technologies in the future.Green & Sustainable Science & Technology || Engineering, Environmental || Environmental Science
Design of an interactive fashion recommendation platform with intelligent systems
Design platform intelligent systems With the increase in customer expectations in online fashion sales, greater integration of fashion recommender systems (RSs) allows more personalization. Design decisions rely on personal taste, as well as many other external influences, such as trends and social media, making it challenging to adapt intelligent systems for the fashion industry. Different methods for recommending personalized fashion items have been proposed, however, the literature still lacks an approach for recommending expert -suggested and personalized items. In this research, an interactive web -based platform is developed to support personalized fashion styling, focusing on users with diverse body shapes. To merge the user's taste and the expert's suggestion, the proposed methodology in this research combines genetic algorithms and machine learning techniques allowing the system to access expert knowledge (including external influences) and incremental learning capability, by adapting to the user preferences that unfold during interaction with the system.Materials Science, Textile
Bargaining With Patriarchy: Newsroom Experiences of Women Journalists in Turkey and Greece
According to feminist news critics, news structure has a gender. It is masculine because the codes and ethics of journalism have been designed in male-ordered newsrooms. Do female journalists make a difference in the news, or is journalism gender-blind? What strategies, interventions, and initiatives are women journalists developing (if they ever can) to cope with androcentric newsroom culture and practices? What are the consequences of their bargaining with patriarchal newsroom hierarchies and practices? The rich news criticism literature's answers to these questions are as complementary as contradictory. Based on in-depth interviews with journalists from Turkey and Greece, this article pictures the hegemanic newsroom culture of the two countries and discusses the bargaining and/or consenting strategies of women journalists with masculinity through rereading the participant narrations.Communicatio
Managing the risks against carbon neutralization for green maritime transport
Maritime transport plays a vital role in global trade. With low transport costs and high service reliability, approximately 80% of products are transported by sea. The international nature of maritime transport supports globalized production and consumption patterns. As a result, maritime transport is uniquely influenced by the convergence of environmental, geopolitical, and social factors. One of the environmental factors linked to maritime transport is emissions. Although many steps have been taken to reduce emissions within the scope of carbon neutrality by implementing new technologies and policies, the volume of emissions produced in maritime transport is still relatively high and threatens global sustainability. This research attempts to estimate the volume of carbon emissions produced by international shipping using the Simple Exponential Smoothing method. After highlighting the situation, this research aims to determine the risks that cause carbon emissions and which should be prioritized using the Graph Theory and Matrix Approach. This approach draws attention to the fact that a scientific basis has remained in the background. This study emphasizes the scientific basis of the method used to estimate carbon emissions, ensuring that geopolitical and social risks are taken into account as well as environmental factors. Thus, it offers a more comprehensive perspective to help managers and decision-makers in developing emission reduction strategies, contributing to the greening of maritime transport.Green & Sustainable Science & Technology || Engineering, Environmental || Environmental Science
A novel stabilized artificial neural network model enhanced by variational mode decomposing
Existing artificial neural networks (ANNs) have attempted to efficiently identify underlying patterns in environmental series, but their structure optimization needs a trial-and-error process or an external optimization effort. This makes ANNs time consuming and more complex to be applied in practice. To alleviate these issues, we propose a stabilized ANNs, called SANN. The SANN efficiently optimizes ANN structure via incorporation of an additional numeric parameter into every layer of the ANN. To exemplify the efficacy and efficiency of the proposed approach, we provided two practical case studies involving meteorological drought forecasting at cities of Burdur and Isparta, T & uuml;rkiye. To enhance SANN forecasting accuracy, we further suggested the hybrid VMD-SANN that integrated variation mode decomposition (VMD) with SANN. To validate the new hybrid model, we compared its results with those obtained from hybrid VMD-ANN and VMD-Radial Base Function (VMD-RBF) models. The results showed superiority of the VMD-SANN to its counterparts. Regarding Nash Sutcliffe Efficiency measure, the VMD-SANN achieves accurate forecasts as high as 0.945 and 0.980 in Burdur and Isparta cities, respectively.Multidisciplinary Science
European approach to the importance of sports management competencies in women's semi-professional teams
The competencies and skills of a good sports manager have always been a controversial and diverse topic depending on the country and the context in which it is analysed. That is why this research aims to show which are the most valued competencies by sports managers in several European countries, taking into account gender differences. A total of 209 sports managers from semi-professional women's teams participated in the research. They completed a questionnaire in which different dimensions were evaluated, assessing the importance of the different competencies of a sports manager. The results showed that greater importance was given to skills related to the management of sports facilities and less to human resources management. Differences related to gender were scarce, with significant differences found only in the competence of Strategic Planning Management. In conclusion, it is difficult to agree on the importance of the competencies of a good sports manager, while agreeing on the need for analysis in the areas of finance, event management, planning and management of sports facilities.Education & Educational Researc
