    The mediating role of self-regulation in the relationship between parenting behaviors and early mathematical development in Peruvian preschool children
    (Hipatia Editorial, 2022-10-01)
    A significant way to contribute in the analysis of deficiencies in school performance, a known issue particularly in mathematics, is by delving into children’s development of informal mathematics during their early childhood, and thus have better elements to intervene in a more timely, effective manner. From this point of view, this study analyzes how the relationship between parenting behavior and early mathematics can be mediated by the development of self-regulation in children. The sample of the study is made of 85 students, between 5 and 6 years old, who are in their last year of preschool in two public schools in Lima. The instruments used are the Spanish translations of the Test of Early Mathematics Ability - 3, Head-Toes-Knees-Shoulders task and Parent Behavior Inventory. The main results show that self-regulation in children and their caregivers’ parenting behavior are significant predicting variables in early mathematical development. Specifically, the findings suggest that self-regulation in children can significantly mediate the relationship between the dimension of support/engagement in parenting behavior and the development of early mathematics in children during preschool.

    Mesa redonda: ¿Derecho administrativo económico, regulación o derecho regulatorio?
    (Pontificia Universidad Católica del Perú, 2025-08-27)
    This roundtable examines one of the central debates in contemporary public law: the relationship between economic administrative law, regulation, and the possible existence of a “regulatory law” as an autonomous branch. One position maintains that no such conceptual distinction exists, as regulation is a multidisciplinary phenomenon whose legal application is carried out through the proper techniques to administrative law. In contrast, another view offers a more nuanced interpretation. It distinguishes between economic administrative law as a legal discipline, and regulation as a specific technique of intervention applied to strategic sectors or those with structural failures. Based on this distinction, it is argued that although regulation is rooted in public law, it exhibits certain modulations that warrant independent consideration. The debate, without doubt, offers the reader a rich confrontation of ideas.

    Identifying the Role of Digital Self-Presentation in Adolescent Identity Formation
    (2025-01-01)
    Objective: This study aimed to identify and interpret the role of digital self-presentation in shaping adolescent identity formation among Chilean youth within the broader context of social media engagement and self-concept development. Methods and Materials: A qualitative research design was employed using semi-structured, in-depth interviews with 33 adolescents aged 14–19 years from Santiago, Valparaíso, and Concepción, Chile. Participants were selected through purposive sampling to ensure diversity in gender, socioeconomic background, and social media usage. Data collection continued until theoretical saturation was reached. All interviews were conducted in Spanish, transcribed verbatim, and analyzed using thematic analysis with NVivo 14 software. The analysis involved open, axial, and selective coding to generate core themes reflecting participants' lived experiences and meaning-making processes in digital environments. To enhance the study's credibility, member checking and peer debriefing were performed. Findings: Three overarching themes emerged: (1) Digital Platforms as Identity Arenas, illustrating how adolescents strategically curate and manage their online personas; (2) Negotiating Authenticity and Social Expectation, revealing tensions between genuine self-expression and conformity to peer norms; and (3) Identity Development through Digital Interaction, emphasizing how feedback, role experimentation, and online reflection foster evolving self-awareness. The findings demonstrated that adolescents actively use social media to construct, test, and regulate their sense of self, while feedback mechanisms and social comparison dynamics significantly influence emotional well-being and self-esteem. Participants with stronger self-regulation and supportive family relationships displayed greater digital resilience and identity coherence. Conclusion: Digital self-presentation functions as both a developmental opportunity and a psychosocial challenge. It enables adolescents to explore diverse self-aspects and foster identity growth while simultaneously exposing them to social pressures and validation dependence. Conscious and reflective engagement in digital spaces can enhance identity integration and emotional balance in adolescence.
