    En las próximas líneas podrán leer un compendio de nueve experiencias de gestión de Responsabilidad Social Universitaria (RSU) desarrolladas en cinco países de América Latina por nueve centros universitarios socios de CLADEA, entre escuelas de negocios, facultades de negocios y administración empresarial de relevantes universidades de nuestra región. Como coordinadora de la Red de Responsabilidad Social de CLADEA, es un honor presentar estas nueve experiencias de gestión que, en conjunto, representan un gran aporte a la construcción de un modelo de gestión de RSU desde América Latina, y que en particular significan un aporte concreto que se ofrece desde las universidades a la sociedad, demostrando que es posible la mejora de la calidad de vida de grupos de personas donde territorialmente la universidad está presente. Estos casos también representan, en simultáneo, un aporte conceptual a la construcción y evolución del concepto de RSU y su generación de valor compartido para la propia universidad y sus diversos grupos de interés, entre ellos: alumnos, docentes, administrativos, ex alumnos, empresas, organizaciones sin fines de lucro, gobierno y otros grupos de interés vinculados con el quehacer universitario. Saludo y felicito muy especialmente a los gestores de estas nueve buenas prácticas en responsabilidad social, así como a sus autoridades y a los autores que se han tomado el tiempo para describir y analizar cada uno de los casos que hoy se publican en este libro. Sabemos que existe en ellos el cumplimiento de su propósito como entidades educativas comprometidas con la sociedad donde están presentes. Los nueve casos que a continuación podrán leer y conocer en detalle describen la experiencia, la vinculación con una sociedad que necesita de una universidad viva que aporta, integra, analiza, investiga y genera desarrollo y valor compartido para todos. Que este libro sirva de inspiración para otras universidades de la región y socias de CLADEA.

    Revisiting Syllables in Language Modelling and their Application on Low-Resource Machine Translation
    (Association for Computational Linguistics (ACL), 2022) Oncevay, A.; Rojas, K.D.R.; Sanchez, L.K.C.; Zariquiey, R.; Pontificia Universidad Católica del Perú
    Language modelling and machine translation tasks mostly use subword or character inputs, but syllables are seldom used. Syllables provide shorter sequences than characters, require less-specialised extracting rules than morphemes, and their segmentation is not impacted by the corpus size. In this study, we first explore the potential of syllables for open-vocabulary language modelling in 21 languages. We use rule-based syllabification methods for six languages and address the rest with hyphenation, which works as a syllabification proxy. With a comparable perplexity, we show that syllables outperform characters and other subwords. Moreover, we study the importance of syllables on neural machine translation for a non-related and low-resource language-pair (Spanish–Shipibo-Konibo). In pairwise and multilingual systems, syllables outperform unsupervised subwords, and further morphological segmentation methods, when translating into a highly synthetic language with a transparent orthography (Shipibo-Konibo). Finally, we perform some human evaluation, and discuss limitations and opportunities.

    Structural damage detection on a full-scale masonry cross-vault subjected to quasi-static cyclic loading tests
    (International Operational Modal Analysis Conference (IOMAC), 2025) Bendezu, A.; Pellegrini, D.; Chácara, C.; Pontificia Universidad Católica del Perú. Departamento de Ingeniería
    This paper presents the results of an experimental campaign for structural damage detection on a full-scale alternative-masonry cross-vault subjected to quasi-static cyclic tests. The masonry constituent material was composed of stabilised compressed earth blocks and soil-cement mortar. The cross-vault specimen presented a square plan with a span of approximately 3.20 m. Its boundary conditions consisted of two fixed corners that restrained displacements and rotations in all directions, and two corners that were placed over four-wheeled steel masses that enabled horizontal displacements. The masonry cross-vault was subjected to incremental horizontal cyclic load following a displacement-controlled approach to capture its in-plane shear failure. A total of 14 cyclic load sequences were applied to the specimen, reaching a maximum displacement of about 40 mm. The damage detection was evaluated in terms of frequency decrease and modal shape variations, estimated by operational modal analyses (OMA) technique carried out every two cyclic loads sequences considering ambient vibrations as excitation source. The Enhanced Frequency Domain Decomposition (EFDD) method implemented in the ARTeMIS Modal software estimated the specimen's frequencies. The results show an important decay in natural frequencies and variations of the first three mode shapes, especially when the vault experienced severe damage.

    Experimental and Numerical Evaluation of Out-of-Plane Seismic Performance of Traditional Dry Stone Retaining Walls in the Central Andes Region
    (Earthquake Engineering Research Institute, 2022) Ita, P.; Daudon, D.; Santa-Cruz, S.; Tarque, N.; Grupo de Gestión de Riesgos de Desastres en Infraestructura Social (GERDIS-PUCP)
    The population that lives informally on the slopes of some cities in the Andes is at high seismic risk due to the lack of technical advice to build their homes, which are settled on non-compacted fill supported by pircas (traditional dry stone retaining walls). The objective of this work was to evaluate the seismic performance of these walls through pseudo-static tests and numerical models applying the discrete element method (DEM), simulating forces in the out-of-plane direction. Three walls of 1 m and three of 1.5 m in height were built. These are the most common dimensions found in the study area (Lima). It was observed that the most frequent failure is due to delamination and overturning of the pircas. It is estimated that the average ultimate resistance to displacement, obtained experimentally, of the walls with heights 1 m and 1.5 m was 31% and 24% of the weight, respectively. For the numerical models, the parameters of the contact forces (stiffness and friction angle) were calibrated using the experimental results. It is concluded that the walls can improve their capacity with a better construction practice.

    Prescriptive model for knowledge management in doctoral programs
    (Interciencia Association, 2017) de la Vega Hernández, Iván Manuel; Rodriguez-Montoya, Cristobal; Yáber-Oltra, Guilllermo E.O.; Pontificia Universidad Católica del Perú
    The expansion of intellectual capital, fueled by the generation of new knowledge, contributes to an increasing wellbeing of society. However, the gap between Latin American and other countries, due to the smaller quantity of scientific papers published and patents filed, presents a problem that requires urgent attention. The doctoral programs offered by our universities, important knowledge producers in our countries, could increase their intellectual production by using knowledge management (KM), in an analogous way to companies that have adopted it. In that sense, the goal of this research is to simplify the adoption of KM processes, formulating a prescriptive model developed from a theoretical and qualitative analysis of the relevant literature, contrasted in the authors' own discussions, from a perspective based on their combined experience as participants and administrators of doctoral programs. It is expected that the use of KM systems, based on the guidelines of the proposed model, will have a positive impact, implying an increased intellectual production of doctoral programs.
