astery of the prerequisite material, particularly the concepts of derivatives and integrals of functions of one variable. Therefore, understanding mathematical concepts is a fundamental aspect that determines students’ ability to understand the interrelationships between topics and solve problems systematically and logically. This study aims to describe students' conceptual understanding of multivariable calculus. The approach used is a descriptive approach with a purposive sampling technique, namely selecting research subjects based on certain criteria in the form of the highest and lowest levels of mathematical concept understanding. The results of the study indicate that students conceptual understanding varies across different materials. In the partial derivative material, students were not yet fully able to accurately represent the solution concept, especially in applying the rules for derivatives of exponential functions, so the results obtained did not conform to mathematical principles. These errors are conceptual in nature and indicate a weak grasp of certain basic concepts. However, in the material on derivatives of products of two functions and triple integrals, students demonstrated goog conceptual understanding. They were able to select, use, and apply solution procedures appropriately and systematically. This finding indicates that despite weaknesses in certain concepts, students still possess quite good procedural and conceptual abilities in the context of other problems in polynomial calculus.

errors in solving mathematical logic problems based on Newman’s Procedure. This research adopts a descriptive qualitative approach involving first year students enrolled in the mathematical logic course within the Information Systems program. Data were collected through a diagnostic test administered to three students representing different levels of academic ability: one low ability student, one moderate ability student, and one high ability student. Students’ ability levels were measured based on tests covering compound propositional logic and logical operations. Data analysis was conducted by classifying errors at each stage of Newman’s Procedure, tracing the underlying factors contributing to these errors, and relating them to students’ logical reasoning abilities. Accordingly, the research method employed in this study is descriptive qualitative research. The resulting error classifications were subsequently used by lecturers as a basis for recommending improvements in instructional strategies. The results indicate that students with low ability made errors across all stages from K1 to K5, students with moderate ability tended to make errors at the case exploration and process skills stages, while students with high ability were able to complete all stages systematically and consistently. These findings confirm that the Newman Procedure is effective in mapping students’ thinking errors. Therefore, the implementation of differentiated learning strategies that emphasize problem comprehension, case exploration, and logical verification is recommended to enhance students’ reasoning abilities

the transition toward a sustainable consumption model. The main focus is directed at three key issues: the right to environmental information, the right to repair, and regulatory challenges related to greenwashing practices. By using a narrative literature review approach, this article examines various academic and policy sources to evaluate the extent to which consumer protection has been integrated into circular economy strategies. The findings show that although positive initiatives have been taken, regulatory implementation remains weak and often fails to provide effective protection mechanisms for consumers. The policy implications proposed include strengthening standards for environmental claims, expanding the right to repair across sectors, and increasing sustainability literacy at the consumer level. This article aims to enrich academic discourse and serve as a foundation for consumer-based policy development in support of the circular economy agenda.

ere detected at an advanced stage, indicating inadequate knowledge and low awareness of early detection. This study aimed to identify factors influencing women’s knowledge of breast cancer through a systematic literature review.
A literature review was conducted using the Preferred Reporting Items for Systematic Reviews. Ten national and international research articles published between 2021 and 2025 were analyzed using a qualitative descriptive approach supported by simple descriptive statistics through vote counting. The results showed that women’s knowledge of breast cancer was influenced by internal and external factors. Internal factors included education level, age, attitudes and awareness, and psychological factors. External factors comprised access to information and educational media, the role of health professionals, educational interventions, socioeconomic status, cultural norms, and family support. Education level and access to information were identified as the most dominant factors based on their frequency across the reviewed studies.
It was concluded that women’s knowledge of breast cancer was shaped by the interaction between individual characteristics and social environments. Comprehensive and sustainable health education strategies were therefore required to improve breast cancer awareness and support early detection practices.
Abstract:The objective of this study was to examine how deepfake-based humor becomes socially acceptable despite its potential to function as digital harassment. This study focused on psychological mechanisms that explain audience…
e tolerance and normalization of harmful, identity-based humorous content in online environments. This study used a scoping review design to map and synthesize existing research across psychology, media studies, and cyberpsychology. The sources were identified through searches in major academic databases and were selected based on their relevance to deepfake technology, digital humor, online harassment, and psychological processes such as moral disengagement, online disinhibition, empathy reduction, and social norm reinforcement. The results indicate that acceptance of deepfake-based humor is commonly supported by four interrelated mechanisms, namely normalization through participatory digital culture, psychological distancing that weakens empathy, moral ambiguity created by humorous framing, and reduced accountability through diffusion of responsibility in online spaces. In addition, the literature conceptualizes deepfake humor as a hybrid phenomenon situated between remix-based entertainment and identity-targeting harm, shaped by platform visibility and engagement dynamics. This review highlights that deepfake-based humor may be tolerated not because it is harmless, but because it is routinely framed as “just a joke,” making its harm easier to minimize and socially overlook. Therefore, this study emphasizes the need for more direct empirical research and stronger interventions to prevent deepfake-based humor from becoming a normalized form of digital harassment in increasingly synthetic digital environments.

ze existing knowledge to address integration challenges these enterprises face. The researchers analyzed 436 peer-reviewed articles from the Scopus database, published between 2010 and 2025, using bibliometric and qualitative thematic techniques based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Findings highlight that digital innovation significantly enhances market access, operational efficiency, and resource mobilization, empowering women entrepreneurs to overcome structural barriers. Gender equality initiatives play a crucial role in creating supportive ecosystems, promoting diverse leadership styles, and fostering inclusive organizational cultures conducive to sustainable business practices. Thematic analyses reveal specific success factors including robust social networks, targeted mentorship programs, and inclusive financial mechanisms. However, systemic barriers persist, notably limited access to capital, entrenched sociocultural biases, and insufficient digital literacy. Methodologically, research predominantly utilizes quantitative approaches, suggesting a need for integrated mixed-method frameworks to better capture nuanced entrepreneurial experiences. Geographical disparities indicate that women entrepreneurs face different challenges and opportunities across developed and developing contexts, underscoring the necessity for context-specific policy interventions. This review adds to our understanding by combining ideas from entrepreneurial ecosystem perspectives, Gender Empowerment Theories, and the Resource-Based View, providing a complete look at sustainable, fair, and digitally innovative business practices. Future research should focus on intersectional methodologies, longitudinal studies, and comparative analyses across diverse contexts.

approach with a confirmatory nature, testing the extent to which the Resource-Based View (RBV) and Stakeholder Theory are confirmed in the context of the regional banking industry. Primary data were collected through a 1–5 Likert-scale questionnaire from all BPD DIY managers (census method, 163 respondents) who met the criteria of managerial position, minimum three years of service, and involvement in strategic policy. Data analysis was performed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with the assistance of SmartPLS. This involved testing the outer model (convergent validity, discriminant validity, reliability) and inner model (path coefficient, R², f², Q²) to assess the direct and indirect effects between variables. The variables studied included business strategy, profitability, CSR, and firm value, operationalized across several dimensions, including future orientation, operational efficiency, the social and environmental dimensions of CSR, and market value and corporate reputation. The instrument was independently developed based on theoretical synthesis (David & David, Houston, Teodorescu Ionescu, Carroll, and others), then validated through expert judgment before being tested for validity and reliability on pilot respondents. The results showed that business strategy had a positive effect on CSR and firm value, while profitability had a positive effect on CSR and firm value, aligning with the view that slack resources and a prospector strategy encourage stronger CSR activities and improved market perception. CSR was shown to have a positive effect on firm value and acted as a mediating variable in the relationships between business strategy and firm value and profitability and firm value. Thus, CSR implementation strengthens the transmission of the influence of strategy and financial performance on increasing firm value. These findings confirm that the integration of a sustainability-oriented business strategy, strong profitability performance, and consistent CSR implementation is a crucial combination for enhancing firm value in the regional banking sector.
