ChatGPT effects on 21st century skills of university students: A systematic review(مقاله علمی وزارت علوم)

حوزه‌های تخصصی:
تعداد بازدید : ۶۴ تعداد دانلود : ۷۰
The study was carried out to investigate effects of ChatGPT on 21st century skills of university students. Since there are several 21st century skills, the study focused on only five (i.e. critical thinking, communication, collaboration, creativity, and problem-solving skills). The study employed systematic review of literature in which PRISMA framework was employed to facilitate selection of studies included in the review. Findings revealed that ChatGPT poses effects to students on each of the 21st century skills. However, the type and magnitude of effects depends on the type of skill. ChatGPT was found to bring more positive impacts to university students’ communication skills while more negative impacts on collaboration skills. While that was the case, the study found that ChatGPT can bring either positive or negative impacts on critical thinking, creativity and problem-solving skills. The effects depend mainly on the magnitude of students’ dependency on it. Those that depend more on it are likely to be more negatively affected. For instance, the more the students depend on ChatGPT, the less the ability for them to think critically and solve problems. The study recommends, therefore, that universities should embrace ChatGPT instead of avoiding it. However, they should find ways to reduce students’ over-reliance on it, among other recommendations.

حوزه‌های تخصصی:
تعداد بازدید : ۵۳ تعداد دانلود : ۶۵
The global demographic shift toward an aging population has driven the growth of senior tourism as a vital and expanding part of the tourism industry. This systematic review synthesizes empirical and theoretical studies published from 1980 to 2025, examining the main motivations, travel preferences, and challenges faced by senior tourists. Using the PRISMA protocol, 31 peer-reviewed studies were systematically identified and analyzed through thematic content analysis in NVivo software. The findings show that senior tourists are mainly motivated by intrinsic factors, such as relaxation, nostalgia, social engagement, and personal growth. At the same time, extrinsic motivators—like destination features and leisure activities—also play a role but are less explored. Preferences among senior travelers are quite diverse, influenced by age, health, socioeconomic status, and cultural background, and reflected in different choices regarding accommodation, travel timing, activities, and services needed. Key barriers to senior travel include physical and health limitations, financial constraints, psychological fears, and infrastructural issues, all of which affect participation and satisfaction. The literature indicates a regional focus on studies from Asia and Europe, with notable gaps in the Middle East and other underrepresented areas. Quantitative methods dominate, highlighting the need for more qualitative and mixed-method research to better understand the lived experiences and changing needs of senior tourists. This review provides an integrated thematic perspective that enhances understanding of senior tourism behavior and lays a foundation for creating more accessible and inclusive travel options that address the complex needs of aging populations.

حوزه‌های تخصصی:
تعداد بازدید : ۶۰
Postmodern tourism is gradually shifting away from mass tourism toward more personalized, experience-based, and interest-driven forms of travel. In response to this trend, many destinations are increasingly emphasizing local cuisine and developing culinary tourism as one of the most dynamic and creative sectors of the tourism industry. However, the successful development of culinary tourism is not possible without a clear understanding of culinary tourists’ behavior. Accordingly, the aim of this study is to explain the behavior of product-oriented culinary tourists, the most specialized segment of culinary tourism, by developing a behavioral model using a mixed-method approach. In the qualitative phase, a meta-synthesis method was applied, while the quantitative phase employed structural equation modeling (SEM) using SmartPLS 4 to identify key dimensions, components, and indicators, as well as to examine the relationships among them. The sample size was determined using the Cochran formula and consisted of 285 participants, who were randomly selected from saffron culinary tourists visiting the Qaenat region. The findings indicate that tourists’ motivation, destination image, and perceived service quality have direct effects on satisfaction and indirect effects on behavioral intentions. Notably, perceived service quality also shows a direct and significant influence on behavioral intentions. Furthermore, the results highlight several key destination characteristics that strongly influence the quality of culinary tourism tours. These include cultural and culinary involvement, accommodation quality, farm-based experiences, food and beverage quality, reliable service delivery, a sense of safety and tranquillity, effective tour organization, and the quality of tour guide services .

Finding all Redacts in Financial Information Systems Based on Neighbourhood Rough Set Theory for Finance Data with Decision Makers Point of View(مقاله علمی وزارت علوم)

حوزه‌های تخصصی:
تعداد بازدید : ۸۹ تعداد دانلود : ۸۶
The Neighborhood Rough Set (NRST) method is a valuable approach for selecting a subset of features from a complete dataset, enabling us to preserve the essential information that the entire feature set provides. In financial datasets, which often contain high-dimensional input features, effective feature selection techniques are crucial to identify the features that yield the most predictable results. In this work, we use neighborhood concepts to discover data dependencies and reduce the number of features in a financial dataset based solely on the data itself, without relying on additional information. This process also includes removing extra features. To facilitate a simple algorithm, we use the properties of neighbourhood rough sets to formulate a Binary Integer Linear Programming (BILP) model. Optimal solutions to these problems are obtained using genetic algorithms. Our approach allows for feature reduction from minimum to maximum cardinality. We demonstrate the efficiency of our proposed method compared to other techniques through various tables showing the results on several benchmark datasets characterized by unbalanced class distributions. The financial dataset used in the present study is taken from the UCI Machine Learning Repository.

A Two-Stage DEA–PROMETHEE II Framework for Fully Ranking Global Retail Firms in a Competitive Environment(مقاله علمی وزارت علوم)

حوزه‌های تخصصی:
تعداد بازدید : ۵۰ تعداد دانلود : ۵۸
Objective : In the competitive global retail industry, achieving sustainable competitive advantage is a key factor for long-term success. This advantage arises when companies effectively utilize their unique resources and capabilities to outperform competitors. Operational efficiency and financial performance are critical for evaluating competitiveness and investment attractiveness. Data Envelopment Analysis (DEA) is a standard method for measuring efficiency, but classical DEA cannot fully rank efficient units. Integrating DEA with multi-criteria decision-making (MCDM) methods addresses this limitation, considering investor-relevant financial ratios. This study proposes a two-stage approach to evaluate and rank retail companies comprehensively.  Methodology: In the first stage, an input-oriented CCR model of DEA is applied, with assets, operating expenses, and the number of employees as inputs, and total revenue and net profit as outputs, to assess relative efficiency. In the second stage, financial indicators—asset turnover, dividend yield, return on equity (ROE), return on assets (ROA), and return on investment (ROI)—alongside DEA efficiency scores are evaluated using the PROMETHEE II method to generate a complete preference-based ranking of retailers. Results : DEA in the first stage provides relative efficiency insights but cannot rank efficient units. Employing PROMETHEE II in the second stage, and considering financial ratios, overcomes this limitation and produces a comprehensive ranking. Validation against DEA, hybrid DEA–PROMETHEE II, and hybrid DEA–AHP rankings demonstrates a strong alignment of the results with the actual market positions of retailers. Conclusion : The proposed method enables investors to identify high-performing companies and provides retailers with a strategic tool to monitor competitiveness, identify strengths and weaknesses, optimize resource allocation, and achieve a sustainable competitive advantage.

Relief Logistics Network Design for Facility Location and Flow Allocation under Environmental Considerations(مقاله علمی وزارت علوم)

حوزه‌های تخصصی:
تعداد بازدید : ۶۶ تعداد دانلود : ۷۲
Objective : This paper develops a single-objective and a bi-objective mixed-integer linear programming model to optimize the post-earthquake relief logistics network involving transfer points, hospitals, and relief centers in Tehran, Iran. The primary aim is to minimize the total time required to transfer injured individuals through the system, while the bi-objective model additionally minimizes penalties for failing to transfer casualties due to capacity shortages.  Methodology: The methodology involves formulating location-allocation models in which demand points, transfer points, hospitals, and relief centers are represented by specific capacity and travel-time parameters. The models are applied to two earthquake scenarios in south-central Tehran: a magnitude-6 event with lower casualties and selective facility activation, and a magnitude-7 event requiring full capacity utilization and a 30% assumed increase in hospital capacity. Results : The model’s effectiveness in optimizing the relief network is demonstrated. For the magnitude-6 scenario, the model selects 10 transfer points, 15 hospitals, and 25 relief centers to minimize total transfer time. For the magnitude-7 scenario, utilizing all available facilities, the model optimally allocates casualties despite severe capacity constraints. Conclusion : The proposed models offer a practical decision-support tool for designing efficient humanitarian supply chains in earthquake-prone urban areas. They underscore the necessity of pre-disaster planning, including establishing transfer points with triage and outpatient capabilities, increasing hospital surge capacity, and ensuring public awareness to direct casualties to designated transfer points.
