    1503: De la memoria, a los objetos, al hogar
    (Universidad Finis Terrae (Chile) Facultad de Artes, 2022) Canala-Echevarría Bauer, Lucía; Edwards Alonso, Raimundo prof. guía; Montero Peña, Valentina prof. guía; Rodríguez Martínez, Margarita prof. guía
    Mi proyecto investigativo nace y se nutre de lo autobiográfico, espacio desde donde surgen mis propuestas artísticas. Comencé abordando la memoria como concepto para luego percatarme de su relación con la identidad y su vínculo con los objetos cotidianos que, desde la niñez, conforman el hogar. Mi objeto de estudio fue mi antigua casa en Providencia, donde pasé mi niñez. Junto a la carga personal y afectiva me interesó acercarme al contexto más colectivo del concepto de habitar, investigando sobre las viviendas de aquel entonces: modelos de construcción tradicionales que transitoriamente fueron evolucionando a los modelos actuales de casa-jardín. De ahí surgió un interés por conocer analíticamente la arquitectura de aquel hogar y su demolición. Me interesa rescatar aquellas particularidades únicas que conforman el hogar y combinarlas con el fenómeno imaginativo que nos entrega la memoria. La casa como aquel espacio construido desde el amor y la ternura para su disfrute y encanto; habitaciones llenas de recuerdos y experiencias, bajo un techo protector. No busco la representación mimética ni la exactitud del recuerdo, busco aquello que hace especial un momento, un espacio, un objeto. Busco la personalidad que acompaña y encanta un lugar, nutrido por quienes habitan en él y los rastros que dejan. Busco aquella (auto)biografía de una niña viviendo en José Manuel Infante, en una casa que ya no existe con una infancia que ya quedó en el pasado.

    1984 es ahora: 70.7 kilómetros de viaje
    (Universidad Finis Terrae (Chile) -- Facultad de Arte, 2017) Gallardo Julio, Tatiana Pamela; Silva Soura, Cristián prof. guía; Bravo Botta, Viviana prof. guía
    Esta memoria aborda el recorrido entre Melipilla y Santiago, más específicamente la Autopista del Sol como eje central de investigación, observando las distintas situaciones que conviven a lo largo de dicho trayecto. Estas se configuran entre el paisaje, sus habitantes y las similitudes que existen con el imaginario del genero distópico cinematográfico, a partir de esto coexisten la deshumanización y el residuo como parte de la visualidad distópica, la que genera un paisaje en decadencia. Es en el trayecto donde se observa la contradicción en un espacio rodeado de naturaleza, que se quebranta ante basurales, pobreza, desgaste y corrosión en superficies, lo que a su vez se traduce en una realidad que se da en muchos otros lugares de Chile, donde a nivel país existe un total de 25.171 familias que viven en condiciones precarias en 657 asentamientos ilegales o campamentos. Considerando las brechas socioeconómicas como algo fundamental para que se generen estas condiciones de vida, junto a esto conviven los residuos, la basura, la suciedad, los escombros, mataderos, fábricas y diversos elementos que remiten a referencias cinematográficas.

    (John Wiley & Sons Ltd., 2026-02) Schoenbaum, Todd R.; Lin, Guo-Hao; Brunello, Giulia; Strauss, Franz J.; Schwarz, Frank; Jung, Ronald E.; Wang, Hom-Lay
    Objectives: To gather the opinions and preferences of experts regarding the number of implants used to support a fixed prosthesis in the edentulous maxilla, timing of implant placement, and timing of implant loading. This was performed using a single-round survey methodology. The primary objective was to support the development of a consensus and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla. Materials and Methods: A custom survey instrument was created by a steering committee and team of experts for the 1st Global Consensus for Clinical Guidelines. The anonymous survey was conducted using a single-round survey method. Consensus was defined as >75% and ≤95% agreement or disagreement, and strong consensus as >95% agreement or disagreement. Results: A total of 202 experts from 42 different countries were identified and invited to participate. 117 provided consent and completed the questionnaire, resulting in a response rate of 57.9%. Strong consensus (>95%) reached on no items. Consensus (>75% and ≤95%) reached on four items: always using CBCT for planning, first molar as distal-most implant site for full-arch fixed prosthesis, use of a lab-fabricated acrylic provisional for full-arch fixed prosthesis, and the use of 4 implants to retain a removable maxillary denture. Conclusion: This survey synthesized the preferences and opinions of experts regarding implant number, timing, and loading for the fixed rehabilitation of the edentulous maxilla to inform a consensus development process and contribute to the formulation of clinical practice guidelines for the management of the edentulous maxilla.

    1st Global Consensus for Clinical Guidelines for the Rehabilitation of the Edentulous Maxilla: Patient and Cross-Disciplinary Expert Single-Round Surveys
    (John Wiley & Sons Ltd, 2026-02) Lin, Guo-Hao.; Brunello, Giulia; Jung, Ronald E.; Kopp, Ina; Schwarz, Frank; Wang, Hom-Lay; Strauss, Franz J.
    Objectives: To gather perspectives from patients and cross-disciplinary experts on treatment practices and outcomes in managing the edentulous maxilla to inform a structured consensus process and highlight areas for future research. Materials and Methods: An 18-item single-round survey was distributed in November 2024 with 68 patients and 68 cross-disciplinary experts. Participation was voluntary, anonymous, incentive-free, and required informed consent. Consensus was defined as >75% and ≤95% agreement or disagreement, and strong consensus as >95% agreement or disagreement. Results: Response rates were 60.3% among patients, and 30.9% among cross-disciplinary experts. Consensus or strong consensus was achieved by patients on 15 statements across nine items and by cross-disciplinary experts on 15 statements across eight items. Items reaching consensus included the use of cone-beam computed tomography, preference for fixed full-arch prostheses, major treatment outcomes, need for hard tissue augmentation, home care regimens, dental implant lifespan, procedure difficulty, cost-effectiveness, and patient-reported outcomes. Both groups also highlighted the need for further research on full-arch implant rehabilitation of the maxilla. Conclusion: Findings from both surveys inform the development of clinical practice guidelines in treating the edentulous maxilla by providing valuable perspectives from patients and cross-disciplinary experts. Areas lacking consensus illustrate real-world variations in treatment approaches, highlight knowledge gaps in the current literature, and reveal important differences among patient expectations, expert opinions, and available evidence.

    (John Wiley & Sons Ltd, 2026-02) Lin, Guo-Hao; Strauss, Franz J.; Brunello, Giulia; Stilwell, Charlotte; Jung, Ronald E.; Kopp, Ina; Schwarz, Frank; Wang, Hom-Lay
    Objectives: This single-round survey on prosthodontic rehabilitation of the edentulous maxilla is one of four clinician surveys commissioned prior to the first Global Consensus for Clinical Guidelines (GCCG). Within the GCCG aim of refining treatment protocols and enhancing patient care, this survey gathered expert insights into best practices, challenges, and treatment outcomes for these complex restorative procedures. Materials and Methods: The 25-item survey was sent to 230 identified experts from 41 countries in October 2024. Participation in the survey was voluntary and without incentives. Informed consent was obtained at the beginning of the survey. All data were collected, stored, and processed anonymously. Results: Of the 230 experts contacted, 123 accessed the survey and 121 provided consent and completed the questionnaire, resulting in a response rate of 52.6%. The survey responses identified 13 statements that reached consensus (>75% but ≤ 95% agreement) and five that reached strong consensus (>95% agreement). These 18 statements were derived from 6 items addressing the topics of anatomical landmarks for tooth positioning, preferred distal implant position, preferred minimum implant diameter, preferred retention method, relevant patient-reported outcomes, and relevant clinician-reported outcomes. Conclusion: This study gathered valuable expert insights to inform a consensus development process for establishing clinical practice guidelines for management of the edentulous maxilla. The survey identified 18 statements from six items that reached consensus or strong consensus among survey respondents. The items not achieving consensus served to reflect real-world implant treatment strategies, identify literature gaps, and highlight any inconsistencies between expert consensus and current evidence.

    27F: Los otros damnificados. Crónicas de una periodista en práctica (2014) de Natalia Sánchez Mella como antecedente de las trazas neoliberales en la ocurrencia del 27F
    (Universidad Finis Terrae (Chile) Facultad de Humanidades y Comunicaciones, 2022) Reyes Saravia, Luisa Alejandra; Carvajal Lazcano, Gustavo, prof. guía
    El presente trabajo de investigación se propone demostrar las trazas neoliberales en la ocurrencia del terremoto y maremoto del año 2010 en Chile, con el fin de evidenciar que el acontecimiento de desastres no es de carácter natural. Para esto, se utilizará como fuente primaria la obra 27F: Los otros damnificados. Crónicas de una periodista en práctica (2014) de Natalia Sánchez Mella. La crónica reconstruye los hechos ocurridos el 27F, así como los meses posteriores, entregando una cobertura del desastre completa en información, contexto y experiencias tanto globales como específicas. De esta manera, se realizarán tres análisis en base a las evidencias expuestas en la crónica, en las cuales se demostrará que el neoliberalismo es el principal factor detrás del debilitamiento del Estado, el bajo financiamiento a instituciones de emergencia, la urbanización y la militarización: cuatro ideas claves a la hora de abordar el concepto de neoliberalismo, así como el de desastre. Asimismo, se demostrará la importancia fundamental de la literatura como constructor de subjetividades ante la dominación discursiva de los medios de comunicación. Por lo tanto, es la relación entre estos conceptos claves con la sociedad, la economía, la cultura y la naturaleza, lo que llevan a demostrar su importancia fundamental a la hora de hablar sobre “desastres socio-naturales”.

    8.8 El miedo en el espejo de Juan Villoro: Crónicas del desastre neoliberal
    (Universidad Finis Terrae (Chile) Facultad de Humanidades y Comunicaciones, 2024) Carabantes, Lucciano; Carvajal Lazcano, Gustavo prof. guía
    La presente tesina se propone describir y analizar la presencia del estado neoliberal evidenciado por el terremoto del 27 de febrero de 2010 en la obra 8.8 el miedo en el espejo (2010) de Juan Villoro. Esta obra es una crónica que narra desde la perspectiva del autor, lo que fue vivir el desastre en Chile en dicho año y observar las consecuencias del sistema chileno y el terremoto en carne propia. El análisis se realizará a partir de dos elementos base desarrollados en un marco teórico en torno al neoliberalismo y el concepto de desastre. Se explora la relación entre los conceptos desde las características de la ideología de libre mercado, su participación e intervención en los desastres, y su exposición por medio de una crónica literaria. Los análisis se subdividen en pos de demostrar las características neoliberales, desarrolladas en el marco teórico, que se evidencian luego de que el terremoto tiene lugar en la obra de Villoro.

    A Batalha do Apocalipse e a internet: repensando as novas formas de produção e circulação do livro de fantasia
    (Amoxtli, 2019-08-08) Gomes, Sabrina Ramos;
    Neste trabalho discutiremosquestões relativas à circulação dos livros de fantasia brasileiros na era da Internet, por meio de um estudo de caso da obra A batalha do Apocalipse (2007), de Eduardo Sporh. Com base nas premissas levantadas por Jenkins (2009) acerca da cultura digital e das discussões de Schiffrin (2006) e Thompson (2013) sobre mercado editorial, além dos conceitos de campo defendidos por Bourdieu (1997), discorreremossobreos processos que envolvem desde a produção até a circulação do livro de literatura nacional fantástica. Analisaremosainda como o público participa de modo cada vez mais ativo desse desdobrar e como se dá o processo demanutenção de leitores, antes mesmo do lançamento da obra, ponderando sobre como os processos que perpassam um livro estão cada vez mais multifacetados, tendo em vista que o “ciclo tradicional” vem sendo remoldado. Concluímos que a revolução na comunicação promovida pelo advento da internet alcançou de maneira ímpar a produção e circulação de livros, de modo que o meio editorial foi remodelado não pela decadência dos livros impressos, mas pelas novas formas de circulação e publicação que foram fundamentais para que os mercados de nicho alcançassem vias mais amplas para percorrerem o caminho autor, editor e público

    A bi-objective optimization model to plan vaccination campaigns aided by temporary centers
    (Wiley, 2026) Montenegro-Dos Santos, Fernando
    Vaccination campaigns have saved thousands of lives and reached even the world’s most remote areas. However, the COVID-19 pandemic significantly changed the strategies for such campaigns. It is now crucial to rigorously consider new factors when planning the operational aspects of these campaigns, particularly for last-mile vaccine dispensing. First, a large share of the population must be vaccinated, with emphasis on vulnerable groups at higher risk. Second, if the virus is highly contagious and capable of asymptomatic transmission, implementing public health measures at vaccination sites becomes paramount. To address these challenges, we propose a bi-objective optimization model to support healthcare decision-making. It defines a schedule for locating temporary vaccination centers and assigning populations to permanent and temporary sites over a planning horizon. Moreover, we formalize and validate a minimum set of properties for a function-based prioritization mechanism to ensure consistent prioritization. One objective prioritizes vaccinating vulnerable groups according to our novel function-based approach, while the other minimizes the operational costs of temporary centers. In the complex environment of a pandemic, the strategic integration and use of temporary and permanent vaccination centers is vital for creating a robust and responsive vaccination strategy. Temporary centers, whose locations are determined by the model, improve access for hard-to-reach groups, contribute to minimizing crowding at permanent sites, and lower infection risks. Our results, demonstrated through a case study, show that the model effectively allocates resources and generates various vaccination plans that cater to different priority levels assigned to each objective, thereby offering valuable decision support.

    ¡A desarrollar y fortalecer el Poder Popular!: la construcción de los Consejos Comunales de trabajadores como eje fundamental del Poder Popular, visto por el MIR (1965-1973)
    (Universidad Finis Terrae (Chile) Facultad de Humanidades y Comunicaciones, 2023) Farías Gómez, Claudio Ignacio; Dussaillant Christie, Jacqueline prof. guía
    El desarrollo del Poder Popular fue uno de los pilares dentro de la concepción marxista- leninista en la izquierda chilena. Desde el Partido Comunista de Chile hasta el MIR vieron que era necesario fortalecer y desarrollar Poder Popular en los sectores más vulnerables en Chile. No obstante, hubo discusiones en torno a cómo se implementaría y dónde, lo que llevó a tener varias definiciones de lo popular y a roces al interior del gobierno de Allende. Fue en los Consejos Comunales de Trabajadores, creados por el MIR, donde se evidenció la mayor muestra de Poder Popular. En esta tesis, se argumenta que los Consejos Comunales de Trabajadores eran el pilar fundamental en la construcción de Poder Popular y democracia directa-participativa en el MIR en la época de la Unidad Popular.

    A Digital-Twin-Enabled Resilience Framework (DTERF) for Machine-Learning-Based Anomaly Detection in High-PV Cyber–Physical Smart Grids
    (MPDI, 2026-08-26) Yanine, Franco Fernando; Hidalgo, Mauricio; Frez, Jonathan; Rao, Challa Krishna; Sahoo, Sarat Kumar
    The rapid integration of solar photovoltaic (PV) generation, distributed energy resources, and advanced communication infrastructures is transforming conventional power systems into highly interconnected cyber–physical smart grids. Although this transition improves sustainability and operational flexibility, it also increases grid-management complexity and introduces cyber–physical vulnerabilities, including false data injection attacks, communi￾cation failures, equipment degradation, and renewable-induced operational instabilities. This paper presents the Digital-Twin-Enabled Resilience Framework (DTERF), a conceptual reference architecture for anomaly detection in high-PV cyber–physical smart grids. DTERF integrates heterogeneous cyber–physical data acquisition, Digital Twin-based contextual representation, machine-learning analytics, explainable decision support, adaptive opera￾tional response, continuous learning, and self-healing capabilities within a unified resilience cycle. The framework is grounded in a structured review and comparative assessment ofcontemporary machine-learning approaches and recent integrated smart-grid research. Itsarchitecture is conceptually evaluated through requirements-to-architecture traceability, examining functional coverage and internal consistency across the complete operational cycle. The analysis shows that DTERF provides explicit architectural mechanisms address￾ing the principal requirements identified in the literature, including contextual anomaly analysis, interpretability, cybersecurity robustness, resilience support, and operational inte￾gration. Rather than proposing a new anomaly detection algorithm or claiming empirical performance superiority, DTERF provides a technology-agnostic architectural foundationfor coordinating complementary capabilities required for resilient anomaly management. Future work should empirically validate the framework using Digital Twin simulation envi￾ronments, representative high-PV distribution systems, cyber–physical anomaly scenarios, and real or utility-derived operational data.

    A educação ecológica à luz da Laudato si’ e sua relação com os outros saberes na dimensão do Ensino Religioso
    (Universidad Finis Terrae, 2021-10-31) Carvalho, Wagner Francisco de Sousa
    O presente artigo tem como objetivo desenvolver o que é a educação ecológica à luz da carta encíclica Laudato si’. Inicialmente, traça um itinerário educativo da Gravissimum educationis, passando pelos principais documentos do pontificado de papa Francisco para, enfim, delinear um mapa constitutivo com definição, elementos e âmbitos desta prática ecologicamente educativa. A proposta inspiradora é a necessidade de reconhecer novos agires sobre o atual estilo de vida escolhido pela sociedade, fazendo refletir que precisa superar a ambígua compreensão de como se houvessem duas crises separadas, a do homem e a ecológica, enquanto que na verdade existe uma única e complexa crise sócio-ambiental. O resultado é identificar a educação ecológica como novo paradigma da vida e sua relação com os outros saberes no processo do ensino religioso.

    A la deriva: un complemento físico y espiritual a través del viaje mochilero
    (Universidad Finis Terrae (Chile). Facultad de Arquitectura y Diseño, 2022) Méndez Morales, Tamara; Naranjo Donoso, Julián prof. guía
    Según La Real Academia Española (2022), a la deriva se define como “Sin dirección o propósito fijo, a merced de las circunstancias; desvío de la nave respecto al rumbo establecido, por efecto del viento, mar o corriente” El viaje a la deriva está asociado directamente con el turismo alternativo, el cual se relaciona con los mochileros. Estos son catalogados por desplazarse a pie, con una mochila en la espalda (Rae, 2022). Es así que se caracterizan por la simplicidad con la que se viaja, por lo que a través de ella se obtiene un final con mucha satisfacción personal. El viaje mochilero sigue un estilo nómada, como el de nuestros orígenes. Con bajo presupuesto, por lo que a diferencia de otros tipos de viajes en donde es crucial decidir el destino, lugares donde ir, buscar alojamiento y ahorrar dinero, los viajes mochileros son viajes flexibles y no se planifican constantemente. Se basan en la espontaneidad que significa la aventura; es decir, dejarse llevar, aprovechar cada hora, ya que es un estilo de vida diferente al que estamos acostumbrados día a día, alejado del caos y la planificación diaria. Los mochileros pueden viajar de manera solitaria y nutrirse con personas a través de sus travesías. Obtienen valor y pasión por conocer culturas, lenguas, gastronomía y experiencias. Por lo que, al momento de llegar a un lugar las personas locales generan más cercanías con ellos, a diferencia de cualquier otro tipo de viaje en el que no suele suceder. En síntesis, viajar a la deriva o en otras palabras “mochilear” abre la mente y permite explorar diferentes opciones que día a día no consideramos. Conviviendo a diario con las personas locales de cada destino, permitiendo conocer en profundidad las diferentes culturas y tradiciones. Generando un relajo y reflexión con uno mismo, aprendiendo de estas situaciones e integrándolas a nivel personal. (García, M. 2019) El siguiente estudio presenta el desarrollo del proyecto “A la deriva” como una experiencia mediante el Turismo Alternativo, que establece diferentes estados del viaje a través de una ruta inserta en la Isla Lemuy, Chiloé. Invitando a turistas a experimentar sensaciones inmersivas, con el fin de promover el conocimiento de viajar a la deriva y así contribuir al desarrollo turístico alternativo y a la preservación de la identidad e idiosincrasia insular.

    A map of collective pedagogical content knowledge as a basis for studying the development of biology teachers’ personal PCK of evolution
    (Routledge, 2024-08-02) Vergara, Claudia
    In the past few decades, a large body of research has been conducted on pedagogical content knowledge (PCK), but further empirical and theoretical studies are needed to enhance our understanding of PCK development. This study aimed to describe the development of PCK of evolution in a group of biology teachers using a modified version of the refined consensus model (Mixed Model), including the five components of PCK from the model elaborated by Magnusson et al. (1999). The qualitative research design involved multiple study cases, including semi- structured interviews and lesson plan meetings. A collective PCK (cPCK) map was generated via content representation interviews with six expert biology teachers and scholars. The ideas expressed by three or more experts were then included in the cPCK map, which was used to assess the personal PCK (pPCK) development of a different group of seven biology schoolteachers using three traits: map area, map shape, and the identity of the concepts included in the map. The findings show that the development of teachers’ pPCK was mainly due to the increase in the map area resulting from the inclusion of new concepts belonging to knowledge of students learning and to the knowledge associated with strategies.

    A new dynamic, secondary-memory metric index
    (Red de Universidades Nacionales con carreras en Informática (RedUNCI); Universidad Nacional de la Plata, 2024-10-07) Paredes, Rodrigo
    Metric space searching addresses the problem of efficient similarity searching in many applications. Although promising, the metric space approach is still immature in several aspects that are well established in traditional databases. Particularly, most indexing schemes are not dynamic, that is, few of them tolerate insertion of elements at reasonable cost over an existing index with none or mild performance degrading; and even less of them work efficiently in secondary memory. The List of Clusters (LC) is a competitive index in main memory. We introduce a new dynamic, secondary-memory variant of the LC. Our new index handles well the secondary memory scenario and is competitive with the state of the art, becoming a useful alternative in a wide range of database applications. Also, our ideas are applicable to other secondary-memory indexes, where it is possible to control the disk page occupation.

    A nomogram for relapse/death and contemplating adjuvant therapy for parathyroid carcinoma
    (Elsevier, 2023-08) Silva-Figueroa, Angélica
    The staging systems proposed to date for PC have not been adequately validated. Recent multivariate have been carried out in large national and international databases to search for prognostic factors for survival and relapse in PC. Advanced age, male gender, high PTH and calcium levels at diagnosis, tumor size >30 mm, angioinvasion, presence of distant metastases, and specific tumor microenvironmental factors, such as parafibromin staining and tumor-infiltrating lymphocytes, have been strongly correlated with decreased OS and CSS, and with increased risk of local and distant recurrence. Because of their prognostic significance, these host and tumor factors should be included in any PC staging system. However, there is a need to promote collaborative PC registry plans to collate data on the above prognostic factors as well as new ways in a standardized global registry. Such a resource could be used to stratify patients with PC and identify those at high risk for relapse and death who may benefit from strict surveillance or adjuvant therapeutic care. PC is an indolent cancer with a high recurrence rate of 3 to 5 years after the first surgical intervention. Progression can remain dormant for decades until patients present with distant metastases. Such heterogeneity and neoplastic latency make OS an ambitious endpoint to achieve, and pursuing OS contradicts the actual needs of patients with this endocrine neoplasm. More relevant endpoints focus on achieving normal blood biochemistry to improve quality of life and intervening to lengthen recurrence/metastasis event-related-free survival. Surgery remains the standard treatment because traditional therapies, such as EBRT and chemotherapy, do not benefit patients with advanced unresectable or metastatic PC, new options are emerging for patients with PC. Genomic and phenotypic profiling can continue to inform personalized therapeutic strategies to expand the clinical options available to patients with PC.
