Equity, Environmental Justice and Governance of Urban Green Spaces: A Bibliometric Review

Wiliam Fernandez Vasquez — Wed, 14 Oct 2026 23:12:38 +0000

This study describes the configuration and evolution of research on equity, environmental justice, and governance of urban green spaces. A bibliometric review of documents indexed in Scopus and SciELO was conducted, complemented by descriptive analysis and science mapping with bibliometrix and VOSviewer. The findings show accelerated growth and a concentration of scientific output in countries with high research capacity. The thematic structure links themes of accessibility and spatial measurement with others concerning environmental justice, governance, and green gentrification. Alongside distribution-oriented approaches, the field includes perspectives that consider participation, recognition, and policy effects. The limited Latin American presence constitutes a relevant geographic gap and highlights the need for broader comparative research across diverse urban contexts.

Contemporary Social Movements: Continued Relevance, Legitimacy, and Representation from the Perspectives of Activists in Peru

Fri, 16 Oct 2026 03:01:33 +0000

This study examined the continued relevance, legitimacy, and representation of contemporary social movements from the perspectives of activists in Peru. A qualitative phenomenological approach was employed with a purposive sample of 38 participants involved in different social movements. Data were collected through in-depth interviews conducted between January and March 2023 and analyzed through coding, category development, and cross-checking among researchers. The findings indicate that social movements emerge from shared experiences of dissatisfaction and injustice and are strengthened through collective identity, organization, alliances, and adaptive capacity. Legitimacy is associated with social recognition and consistency between demands and actions; representation depends on the connection between grassroots constituencies and those who articulate their interests; and continued relevance is linked to the ability of movements to preserve their social significance in changing contexts

Personalized Use of ChatGPT and Its Association with Autonomous Learning among University Students

Fri, 30 Oct 2026 00:33:40 +0000

This study examined the association between personalized use of ChatGPT and autonomous learning among university students. A quantitative, non-experimental, cross-sectional, correlational study was conducted with 500 students from an Ecuadorian higher education institution. Two questionnaires were administered to assess the perceived personalization of ChatGPT use and autonomous learning. The results showed a positive and statistically significant association between the two variables (ρ = 0,61; p < 0,001). Likewise, content personalization (ρ = 0,54), learning-process personalization (ρ = 0,46), and interaction personalization (ρ = 0,49) showed moderate associations with autonomous learning. The findings indicate that higher perceived levels of personalization tend to coexist with higher levels of academic autonomy; however, the study design does not permit causal inferences.

Teaching Strategies for Developing Statistical Competencies in Higher Education: A Critical Literature Review

Gerardo Antero Barba Urena, Juan Pedro Soplapuco-Montalvo — Fri, 30 Oct 2026 23:58:58 +0000

This paper critically analyzed teaching approaches reported in the literature on the development of statistical competencies in higher education. A thematic documentary synthesis was undertaken using publications cited in the source manuscript and selected for their direct relevance to statistics education and related quantitative disciplines. Four themes were identified: problem-based and contextualized learning, blended instruction, interactive computational resources, and research-oriented learning. The examined publications describe opportunities to support student engagement and knowledge application, but their varying designs and scope do not allow claims of comparative effectiveness or pooled effect sizes. Teaching strategies should therefore be aligned with explicit learning outcomes and assessed using appropriate measures of statistical competencies. Incomplete documentation of the original search process prevents this work from being classified as a fully reproducible systematic review.

Detection by Circulating Tumor DNA and Multiorgan Cytoreductive Intervention in Retroperitoneal and Cervicofacial MPNST

Tue, 03 Nov 2026 04:39:28 +0000

A synthetic cohort of 1,000 malignant peripheral nerve sheath tumor (MPNST) cases, equally distributed between retroperitoneal and cervicofacial locations, was analyzed to evaluate the relationship between circulating tumor DNA (ctDNA), tumor burden, surgical complexity, and recurrence. Retroperitoneal tumors showed larger size and volume, higher frequency of high-grade disease, and greater preoperative ctDNA levels. Preoperative ctDNA demonstrated discriminatory ability for baseline metastasis (AUC = 0.818) and high histological grade (AUC = 0.764). Although postoperative ctDNA persistence was initially associated with recurrence, it lost independent significance after multivariable adjustment, whereas R1/R2 margins, baseline metastasis, and high-grade disease remained significant predictors. Longitudinal analysis showed decreasing ctDNA levels in non-recurrent cases and increasing levels in recurrent cases. These findings reflect the behavior of a synthetic model and require validation using real clinical data.

Shared Custody and Its Relationship with the Best Interests of the Child and Adolescent: Challenges for Harmonious Family Coexistence

Tue, 03 Nov 2026 05:38:13 +0000

This study aimed to analyze the relationship between perceptions of harmonious shared custody and recognition of the best interests of children and adolescents in the Peruvian context. A quantitative, non-experimental design with a descriptive-correlational scope was employed. The sample comprised 100 participants involved in legal, institutional, and family-related contexts. Data were collected using a 22-item questionnaire with a five-point Likert scale. The results showed favorable assessments of 94% regarding shared custody and 92% concerning the best interests of the child, with a reported Spearman correlation coefficient of ρ = 0.9677. The findings indicate a positive association between perceptions of the two variables. However, this association does not establish causal effects or directly measure children's well-being.

Guadua angustifolia Kunth in the Phytoremediation of Domestic Wastewater Using Constructed Wetlands

Tue, 03 Nov 2026 06:43:18 +0000

The objective of this research was to evaluate the efficiency of Guadua angustifolia Kunth in the phytoremediation of domestic wastewater through artificial wetlands of vertical subsurface flow. An experimental study was developed with three treatments: a wetland with five plants (H1), another with ten plants (H2) and a control system without vegetation (Ht). Biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total suspended solids (TSS), oils and fats and thermotolerant coliforms were analyzed. The results showed that H2 reached the highest removal percentages, with 98.0% for BOD5, 97.0% for COD, 95.5% for TSS, 69.1% for oils and fats and 80.5% for thermotolerant coliforms. Likewise, this treatment presented a favorable behavior regarding compliance with the Maximum Permissible Limits established in Peruvian regulations. It is concluded that Guadua angustifolia Kunth presents potential for its application in decentralized domestic wastewater treatment systems, particularly as an environmentally sustainable sanitation alternative.

Analysis of Media Competence in Secondary School Students

Fri, 06 Nov 2026 00:00:00 +0000

The objective of this study was to analyze scientific evidence on media competence among students in regular basic education, considering its formative dimensions and pedagogical strategies. A systematic literature review was conducted using a qualitative synthesis approach, following the PRISMA 2020 guidelines. Twenty studies published between 2022 and 2026 involving primary and secondary education students were analyzed. The findings were organized into four dimensions: cognitive, communicative, socioemotional, and pedagogical-sociocultural. The results highlighted the importance of critical thinking, information evaluation, digital safety, and contextualized educational interventions. It is concluded that frequent technology use does not guarantee the development of media competence. Therefore, intentional pedagogical strategies are necessary to strengthen students' critical and communication skills, as well as their responsible participation in digital environments.

Legal Foundations and Implications of International Judgments Concerning Legal Infractions in a Constitutional State Governed by the Rule of Law

Sun, 08 Nov 2026 23:37:21 +0000

This study aimed to analyze the legal foundations and implications of international judgments establishing state responsibility within the framework of the constitutional rule of law. A qualitative, documentary, and doctrinal legal study was conducted using hermeneutic, systematic, and comparative methods. Twenty normative, jurisprudential, and doctrinal sources were examined and organized into five analytical categories. The findings distinguished international state responsibility from criminal sanctions, identified the legal foundations underlying the binding force of judicial decisions, and established three dimensions for assessing their legal effectiveness: normative, institutional, and rights-protective. The analysis also demonstrated that the binding nature of international judgments does not, in itself, guarantee their effective implementation, which requires appropriate institutional mechanisms and compliance procedures. The study concludes that international judgments contribute to the protection of fundamental rights, although their effectiveness must be assessed by verifying the implementation of the measures ordered.
