Onshore surface–subsurface correlation of orogenic structures and the continuation of the late Paleozoic Gondwanides in the Tierra del Fuego fold-and-thrust belt, southern Patagonia

Background The Cretaceous–Cenozoic Tierra del Fuego fold-and-thrust belt in southern Patagonia exposes Paleozoic–Cenozoic rocks recording the protracted, subduction-dominated tectonic evolution of South America, from Cambrian–Ordovician magmatism to Permian metamorphism, Jurassic...

Stochastic Analysis of Competing Opinion Dynamics with Trend-Following, Opposition, and Indifference

Abstract. We analyze a stochastic model for the diffusion of two competing opinions in a population composed of trend-followers, opposers, and indifferent individuals. The model introduces a reinforcement mechanism modulated by parameters representing these behavioral types, resu...

Development and Preliminary Validation of a Tool to Assess Trainee Teachers’ Perceptions and Use of Digital Sources in a Historical-Thinking Framework: A Conflict Context in Chile

This article presents the development and preliminary validation of a questionnaire examining trainee teachers’ perceptions and use of digital sources in La Araucanía (Chile) as a source of information about the regional State–Mapuche conflict, within a framework informed by hist...

Evidence-Based Quality Assurance in Initial Teacher Education and Educational Sustainability

Quality assurance in Initial Teacher Education (ITE) has evolved from compliance-oriented approaches toward more comprehensive frameworks emphasizing continuous improvement, evidence-informed decision-making, and educational sustainability. Nevertheless, across Latin America, per...

Predicting consumers' intention to purchase local foods with GI certification: the interplay of consumer ethnocentrism, place identity, attitude and perceived credibility of origin-labelling

Purpose Nudging consumers to choose local products is gaining importance for relocalisation of agri-food system. Origin labelling, such as Geographical Indication (GI) certification, is being widely promoted as a tool of place branding and for signalling the localness of products...

Plural Social Justice in the Graduation Profiles of Social Work Programs at Chilean State Universities

This article analyzes the explicit and implicit presence of social justice in the graduation profiles of Social Work programs at Chilean state universities, as well as the way in which its distributive, recognition, and participatory dimensions are articulated within the declarat...

Inspection-Oriented Predictive Quality Modeling for MDF Manufacturing Using Industrial Process Data and Machine Learning

Continuous medium-density fiberboard (MDF) production presents a persistent quality-assurance problem: destructive laboratory tests return results too late to prevent off-specification material from accumulating before a corrective response is possible. This study develops an ins...

Data-Driven Ensemble Machine Learning for Multi-Horizon Microalgal Bioprocess Forecasting

Microalgal bioprocesses increasingly rely on predictive modelling to support automated control and reduce the cost of laboratory experimentation. Yet, the scarcity of high-quality datasets and the nonlinear nature of microalgal growth severely limit the accuracy and robustness of...
