Published: January 2025

Shape control during nanocrystal synthesis enables tunable physico-chemical properties that emerge at the nanoscale. While extensively studied in plasmonic metal nanoparticles and semiconductor quantum dots, shape control remains less explored in plasmonic heavily doped semiconductor nanocrystals. Here, we report the synthesis of cesium-doped tungsten oxide (CsxWO3-δ) nanocrystals with exquisite shape control achieved through continuous injection synthesis combined with precursor-mediated facet-selective growth. We demonstrate that the anisotropic growth of CsxWO3-δ nanocrystals strongly depends on the precursor injection rate, which we attribute to the material’s intrinsic structural anisotropy and contrasting reaction kinetics on different crystallographic facets. Furthermore, we reveal that halide ions in the reaction medium are critical for passivating and suppressing growth of Cs-exposed basal planes. By systematically modulating the shape aspect ratio, we achieved an extended range of nanocrystal morphologies, leading to broad tunability of LSPR spectra, spanning the entire near-infrared region and extending into the mid-infrared. Computational simulations effectively reproduce the observed shape-dependent optical properties and highlight size-dependent damping behavior consistent with the free electron model. These findings provide a robust experimental methodology for shape control in structurally anisotropic nanocrystals and offer theoretical insights into tunable LSPR properties of heavily doped plasmonic semiconductor systems.
Towards a Theoretical Understanding of Excitonic Properties of Pthalocyanine Thin Films. I. Low-Temperature Exciton Absorption Spectra
Authors: Sengupta Sanghita , Pei Zheng , Lander Chance , Zhang Yu , Furis Madalina , Shao Yihan
Published: January 2025

Phthalocyanine (Pc)-based molecular thin films have emerged in recent years as a promising class of organic semiconductor materials for achieving a long exciton coherence length and a high exciton diffusion coeﬀicient. However, the dependence of their exciton properties on the dimensionality and temperature of the Pc systems, existence of metal ions, and chemical modifications to the Pc molecule is not yet fully understood. As a first step towards a more comprehensive theoretical understanding of the excitonic properties of Pc thin films, we model the low-temperature exciton absorption spectra through employing the Frenkel Hamiltonian and incorporating quantum chem- istry based site energies and exciton-exciton couplings. The predicted exciton absorption spectra of octabutoxy phthalocyanine (H2-OBPc) was found to be strongly dependent on the dimensionality of the model as well as the distance cutoff for including the monomer-monomer exciton coupling. The best match to experimental low-temperature absorption spectra requires a 2D or 3D model and an inclusion of at least the nearest-neighbor and second-nearest-neighbor exciton couplings. We also caution that the widely used dipole-dipole coupling approximation can substantially overestimate the coupling of excitonic transition densities on different monomers.
CONTEMPORARY ART IN GLOBALIZATION CULTURAL TRANSFORMATIONS: ANTAGONISM AND TEMPORALITY
Authors: Petrenko Dmitry
Published: January 2025

This article considers the strategies of art conceptualization in theoretical explorations of the late 20th and early 21st centuries. It is proposed to critically review the concepts of postmodernism and metamodernism as those that are devoid of heuristic potential and no longer correspond to current theoretical demands. One of the main shortcomings of postmodern theories of art is their lack of understanding of the antagonisms that determine the cultural and political-economic processes of the early 21st century. To break a deadlock of postmodern theories, it is suggested to consider art within theories of modernity and globalization transformations.

Philosophical understanding of globalization is possible if to spatially and temporally clarify its meaning. World concepts are critically reviewed in the modern philosophy of A. Badiou, J.-L. Nancy, E. Glissant and in the art curatorial practices of J.-H.Martin, H.-U.Obrist It is important to distinguish between the understanding of the world as Mondus, which in the historical tradition is connected with finitude, and the geometric interpretation of the world as Globus, which denotes perfection and infinity. Mondialization is accordingly opposed to globalization, as the polyphony of unification. While another approach determines the dependence of globalization on postmodern theories and emphasizes the relevance of the very concept of globalization, which is considered in the temporal dimension.

An alternative to postmodern and metamodern concepts of art can be formed on the basis of the philosophical explorations of P. Osborne and K. Bishop. They define contemporary as the temporality of globalization. Art becomes contemporary when it reproduces the antagonisms between the globality of totalization and the locality of subjective positions, between historical time and the multiplicity of temporalities. As an example of modern art of "double coding", the projects of the fictional art association Atlas Group are considered. Particular attention is paid to curatorial practices within the concept of dialectical contemporaneity by K. Bishop. The researcher opposes the coexistence of multiple temporalities and "presentism", fixation on the present time. It is substantiated that modern art not only represents antagonisms but also performs a prognostic function and constructs a political imaginary.
KNOWLEDGEON THE MARKET: THE DILEMMA OF SCIENCE POPULARIZATION
Authors: Podolska Tetiana , Tahlina Yuliia
Published: January 2025

Modern science is complicated and redundant for ordinary people. In the rapidly evolving landscape of modern science, the intricacies of research and discovery often find themselves distilled into digestible forms for the general public. This simplification, however, may not be sufficient in a world where science competes for attention in a marketplace flooded with information. The article delves into the shifting dynamics of science popularization, transcending traditional educational roles and venturing into the realm of marketing. In this era, science is not merely a body of knowledge; it is a brand, and its promotion necessitates a blend of credibility and emotional appeal. The narrative explores how the popularization of science is undergoing a transformative shift, moving beyond the educational sphere and embracing marketing strategies. The article contends that, in order to gain public trust, science is increasingly presented as a marketable "product" with the tagline “Confirmed by science”. This phenomenon reflects a departure from conventional educational approaches, as science seeks to inspire confidence in consumers akin to commercial products.Moreover, the article examines the role of pop culture in reinforcing trust in rational knowledge through emotional connections. It explores how honorable names, ethical considerations, and the self-evident nature of scientific findings contribute to the creation of a new mythology around science. In this context, science becomes more than a set of facts; it transforms into a narrative that resonates with individuals on a deeper, emotional level.The discussion within the article is framed around the ambivalence inherent in these modern methods of science popularization. While the blending of science and marketing may enhance accessibility and engagement, it also raises questions about the potential distortion of scientific information and the ethical implications of turning knowledge into a marketable commodity. The article aims to stimulate reflection on the evolving relationship between science, marketing, and popular culture in shaping public perceptions of scientific endeavors. It turns scientific knowledge into new mythology. This article is devoted to ambivalent modern methods of science popularizing.
THE DIFFERENCE BETWEEN THE CONCEPT OF JUSTICE IN THE CONSTITUTION OF AFGHANISTAN AND THE REPUBLIC OF KAZAKHSTAN

Published: January 2025

The pursuit of justice has remained a fundamental but elusive goal throughout human history, often subject to interpretation and debate among scholars of philosophy and law. Many countries enshrine the principle of justice in their constitutions, yet its precise meaning and application vary widely. In the constitutions of nations like the Republic of Kazakhstan and the Islamic Republic of Afghanistan, the concept of "justice" is notably vague, lacking clear definition or foundational research. In a recent research paper, the author undertook an examination of justice as articulated in the constitutions of Afghanistan and Kazakhstan. Employing a librarian method for information gathering and utilizing comparative analysis, the author sought to elucidate the understanding and treatment of justice within these constitutional frameworks. The findings of this investigation reveal a nuanced picture. In both cases, the concept of justice appears to prioritize the fairness of legal texts over their practical implementation. However, a notable distinction arises in the Constitution of Kazakhstan, where emphasis seems to be placed on actualizing justice rather than merely espousing its principles in legal documents. This brief comparison underscores the complexities inherent in conceptualizing and realizing justice within constitutional frameworks. It highlights the need for further research and analysis to bridge the gap between legal theory and practical application in the pursuit of justice within diverse socio-political contexts.

Published: January 2025

This study investigated the impact of varying steel fiber ratios by volume on the performance of HSC slabs. Incorporating steel fibers into high-strength concrete (HSC) has been shown to significantly enhance its mechanical properties, particularly by improving its load-bearing capacity. Furthermore, the addition of steel fiber reduces the reliance on traditional reinforcement bars, leading to a more efficient use of materials. This not only simplifies the construction process but also contributes to a reduction in overall construction costs. This study investigated the behavior of HSC slab specimens under loading and elevated temperatures. Three groups of specimens were created based on their thickness (8 cm, 12 cm, and 16 cm) using a single high-strength concrete mixture and four varying steel fiber proportions (0, 37.5, 75, and 150 kg/m³). Two-point monotonic loading was applied to each slab specimen until failure. To determine the splitting tensile strength, 12 cylinders were cast. Additionally, 84 cubes were cast to assess the effects of elevated temperatures and different cooling techniques on compressive strength (fcu). The results revealed that incorporating steel fibers into high-strength concrete slabs has a negligible effect on the concrete's density and compressive strength. However, it notably enhanced the splitting tensile strength and modulus of rupture. These improvements significantly boosted the material's resistance to cracking, making it more durable and better suited for applications requiring superior tensile performance. This is particularly important in structures subjected to dynamic or cyclic loading, where the risk of cracking and failure is greater. Doi: 10.28991/CEJ-2025-011-01-013 Full Text: PDF

La temporalidad arquitectónica como objeto experiencial estético
Authors: Castellanos Garzón Giovanni , Agudelo Castañeda Jairo Humberto , Bustacara-Panzza Sandra Marcela
Published: January 2025

Esta investigación busca demostrar cómo la concepción de la temporalidad permite a la arquitectura evolucionar en distintas direcciones. Esta multiplicidad marca a la arquitectura y abre la posibilidad a la percepción estética hacia una intensidad de mediaciones y bifurcaciones espacio-temporales en movimiento, que a su vez constituyen un acontecimiento inesperado y diverso para el individuo. De modo que, los espacios fijos se convierten en permanentes dilataciones; de la misma manera, los tiempos cronometrables cambian a flujos y regulación, observados estéticamente como consecuencia de la transformación y de los procesos que el tiempo establece. Para ello, la metodología utilizada capta las relaciones comunes que se crean entre diferentes obras, en el espacio en el que se insertan, con el fin de resaltar la interdependencia entre distinciones bajo el concepto de “tiempo” y “temporalidad”. Se concluye que el potencial de tal lectura se dirige hacia una arquitectura que dé forma al cambio, a la fluidez y a la ingravidez que marca toda realidad; una arquitectura que no aspire solo al des-orden estético, sino a la lenta permanencia de manera existencial.
Habitar poético y ciudad. Fundamentos, metasignificaciones y utopías
Authors: GASCA SALAS JORGE
Published: January 2025

El ‘habitar poético’, es un concepto incorporado gradualmente a las ciencias sociales, las humanidades y las artes. Con él es posible identificar e imaginar alternativas edificatorias del espacio antrópico y de formas de socialidad que hoy resultan utopías, señalan rutas potencialmente posibles y permanecen vivas en las relaciones de vida comunitaria, la solidaridad humana en el campo y en las ciudades. De no precisarse correctamente su origen ontológico, sus fundamentos histórico-políticos, sus metasignificaciones estético-semiológicas y su alto contenido de utopía, se corre el riesgo de malinterpretar y deformar su sentido originario.
El objetivo principal de este artículo de investigación es la exposición de los fundamentos del concepto ‘habitar poético’, la incursión crítica en las metasignificaciones de los sentidos de su uso, su deconstrucción utópico-política y sus implicaciones. Metodológicamente se parte de la distinción analítica óntico-ontológica empleada por Heidegger en el sentido primigenio del concepto empleándose la hermenéutica y la semiótica como recursos descodificadores del habitar poético, del “poetizar y la estetización de la vida social”. Finalmente se emplea la deconstrucción sistémica, señalándose un conjunto de indicadores políticos que marcan la dirección y el sentido del habitar poético como dominio de la utopía y la esperanza de un ethos poético.

Published: January 2025

Citrus crops are vital contributors to the global agricultural economy. However, they are susceptible to various diseases that can significantly impact yield and quality. Early detection and management of these diseases are crucial for maintaining healthy citrus orchards. In this study, we propose a deep learning-based approach for the automated prediction of diseases affecting citrus leaves and fruits using the VGG16 convolutional neural network model. The proposed model leverages transfer learning, utilizing the pre-trained VGG16 model, which has demonstrated effectiveness in image classification tasks. We assemble a dataset comprising images of healthy citrus leavesandfruits,alongwithimagesdepicting commondiseasessuchascitruscanker,citrus greening,andcitrusblackspot.Theseimages are preprocessed and augmented to enhance model generalization and robustness. The VGG16 model is fine-tuned on the citrus dataset,wherethelastfewlayersarereplaced withcustomfullyconnectedlayersfordisease classification.

MERA HAOCHONGBA & ITS SIGNIFICANCE
Authors: N. Dinesh Singh
Published: January 2025

Manipur is a small state but it has a rich cultural heritage besides its varieties of games and sports both indoors and outdoors. Among the games and sports, polo, which has now become an international game, originated in this erstwhile an independent kingdom. There is also a kind of game called Yubi Lakpi which is similar to Rugby. Boat races are held annually in the presence of the king and his noblemen. As for festivals, hardly a month passes without a festival or two. The festivals include, inter alia, Mera Haochongba, Yaoshang, Ningngol Chakkouba and Lai Haraoba. Mera Haochongba is celebrated on the 10th of Mera, a Manipuri lunar month which falls in September/October. During the reign of King Pamheiba, another festival known as Kwak Tanba was introduced and it was celebrated on the same day and it created some inconvenience. So, the celebration of Mera Haochongba was changed to the 15th of Mera while the newly introduced festival was celebrated on the tenth of the same month. Some scholars say that this festival was introduced during the reign of King Pakhangba (33-154 CE) though there are no written records. However, records clearly prove that this festival had been celebrated during the reign of King Loiyumba (1074 CE – 1122 CE). This festival is related to the tribute of the hill men to the King of Manipur. They brought vegetables grown in the hills and precious or rare collections in their possession. They were accorded warmly in the palace and fed to their heart’s content. This festival aims to have unity and integrity of the then kingdom which has now become an Indian state.

Imagen, imago, selfie:
Authors: AGUILAR ALCALA SERGIO JOSE
Published: January 2025

Este artículo propone una lectura del fenómeno de la selfie a partir de la comprensión del sujeto, el Yo, la identidad, la identificación, la imagen y la imago que provee el escrito de Jacques Lacan sobre el estadio del espejo. Se establecen críticas a los modos en que, desde los estudios de comunicación, se entiende la selfie como una expresión de la identidad del individuo. La lectura psicoanalítica no permite asumir una identidad que no esté ya atravesada por la otredad, lo que resulta en una comprensión de la selfie que va en contra de la presunción de un Yo que tiene control sobre su propia imagen, y que permite señalar los modos en que la selfie produce e impone condiciones de autoexplotación neoliberal del sujeto contemporáneo.
La memoria como red social pública en Black Mirror
Authors: Maturano Soledad Julieta
Published: January 2025

En el presente texto analizo la serie británica de ciencia ficción Black Mirror (2011), a partir de dos episodios: “Toda tu historia” (2011) y “Arkangel” (2017). La elección de esta producción audiovisual la hago con el propósito de problematizar las transformaciones contemporáneas de la memoria, íntimamente relacionadas a la digitalización y virtualización de las relaciones sociales. Asimismo, se halla aquí un interés vinculado a los modos de recordar y de olvidar en sociedades donde la tecnologización se impone como forma de narrar lo afectivo. Abordo una memoria individual y ensimismada que funciona como correlato de un tipo de socialización que está bajo el imperativo del control. De tal manera, llevo adelante una lectura sobre algunas de las consecuencias de la digitalización de la memoria humana como, por ejemplo, una literalidad paranoica de lo que ocurrió en detrimento de una vinculación que asuma rasgos humanos de la memoria, como la falibilidad. Para llevar adelante el trabajo, además de una lectura crítica de la serie, recupero estudios sociales sobre la cultura digital y el capitalismo cibernético. Aquí, hay una confluencia entre el análisis de lo que sucede con los personajes de cada episodio, al mismo tiempo que se pone en diálogo las decisiones de los mismos con distintas perspectivas que recupera el campo de la Comunicación Social.
La extimidad según el psicoanálisis. Otras lecturas posibles sobre la exhibición de la intimidad en redes sociales.
Authors: Arias Valentina
Published: January 2025

El concepto de extimidad es ampliamente utilizado en las ciencias sociales para referirse a las prácticas de exhibición de la intimidad, un fenómeno gestado a comienzos del siglo XXI con la llegada de los medios digitales, Internet y las redes sociales. Notablemente, a mediados del siglo XX el psicoanálisis había acuñado el mismo término, no para referirse a un fenómeno histórico específico sino a una cualidad propia de la constitución psíquica. La concepción psicoanalítica de extimidad difiere considerablemente de la utilizada en ciencias sociales: en este caso, no es un antónimo de intimidad sino un neologismo que designa el origen externo de lo más íntimo del sujeto. Esta perspectiva obliga a pensar los pares interior/exterior y privado/público más allá de su dicotomía, subraya la relación constitutiva que el sujeto tiene con el otro, y fundamentalmente, ubica a la imagen propia en un lugar central en tanto fundante del yo. El objetivo de este ensayo es presentar el concepto de extimidad según como lo entiende el psicoanálisis, a los fines de poner de manifiesto que se trata de una herramienta con gran potencia analítica para abordar las prácticas digitales contemporáneas.

Published: January 2025

Collections of plant genetic resources are the guarantor of the preservation of both natural biological diversity and breeding achievements. Basically, genetic collections consist of seeds and, proper storage in optimal conditions is a necessity (it frees them from frequent reproduction associated with material and labor costs). It is necessary to search for optimal natural conditions for long-term storage of seeds, because in case of emergency situations of a technogenic nature, they will be the most vulnerable. A long-term experiment of long-term storage of agricultural plant seeds in permafrost conditions is being carried out. The aim of research is to find optimal and safe conditions for long-term storage of seeds and grain for both sowing and food purposes, and to study the conditions of natural storage facilities for creation of strategic reserves of seeds and food. In 2010, consignments of seeds of the main grain crops were put into storage (spring wheat, spring barley, winter rye and oats); in 2016, a seed collection of 26 varieties of 8 types of vegetable crops was laid. Meteorological observations were carried out, thermographs and hygrographs were used in the storage. The first sample extraction took place after 6 years of storage. Laboratory analysis of seed quality was carried out using the following standard methods: GOST 12036-85; GOST 12038-84; GOST 12041-82; GOST 12042-80; and GOST R 52325-2005. The results showed high viability of seeds of grain and vegetable crops. Seeds of all samples of grain crops met the requirements for reproductive seeds (germination over 87 %) according to GOST R 52325-2005. Seeds of 17 samples of vegetable crops retained germination at the first-class level in accordance with the requirements of GOST 12038-84. Long-term meteorological observations show a gradual warming of the Arctic climate due to relatively high summer temperatures. In general, the continentality of the climate is growing. The experiment continues, most of the above seed batches remain in storage, further expeditions with the extraction of samples are planned for 2025, 2035 and 2050. The obtained weather data indicate an increase in the continentality of the Arctic climate and its general warming. The data obtained on the viability of cereal grains and vegetable seeds during long-term storage show the effectiveness of using permafrost conditions for this purpose.
Analysis of the main stages of improvement of technical means for the application of mineral fertilizers
Authors: Azarenko V. V. , Zheshka A. A.
Published: January 2025

In the Republic of Belarus, crop yields have increased 3.5–5 times over the past 60 years due to the combined result of work in the field of breeding, mechanization of fertilizers and chemical plant protection products application, which is a significant achievement of science and practice [1, p. 28]. One of the main criteria for evaluating the effectiveness of mineral fertilizers is considered to be the payback of 1 kg of NPK, which should be at least 8 kg of grain or 10–12 feed units by all crops on arable land [2, p. 113; 3]. To achieve such results, spreaders must perform high-quality distribution of mineral fertilizers within the established agrotechnical deadlines. The criterion for assessing the quality of the distribution of mineral fertilizers over the field area is the coefficient of variation, which is defined as the ratio of the standard deviation to the average dose. In addition to uniform distribution over the field area, high-quality incorporation of mineral fertilizers with tillage tools is also essential. As for the timeliness of applying the specified doses of fertilizers within the established agrotechnical deadlines, the most important factors here are the availability of equipment at farms during the busiest period and provision of high-performance fertilizer spreaders. It should be considered, that agricultural chemicalization machines are used from early spring to late autumn, and their annual load exceeds the same indicator for other agricultural machinery. In addition, the operation of fertilizer spreaders involves interaction with aggressive media, which imposes appropriate requirements to ensure their reliability. It should be noted that currently unmanned aerial vehicles are beginning to be actively used to introduce chemicals [4, p. 2]; publications on the development and testing of nanofertilizers are increasingly appearing in the scientific literature [5, p. 319]. In this regard, in order to determine further trends in the improvement of technical means for fertilization, it is necessary to analyze the main stages of the development of these technical means and identify the distinctive stages of their improvement.
Legal science: reflection of reality and formation of the image of the future
Authors: Vasilevich G. A.
Published: January 2025

The article is devoted to the consideration of the state of legal science and the main directions of its development at the present stage. Attention is emphasized on the availability of scientific potential capable of making the national legal system even more effective, combining the account of achievements of foreign science and its own national interests. The importance of legal monitoring and assessment of the regulatory impact of legal norms as the most important tools to improve the rule­making and law enforcement activities was emphasized. Attention is paid to the necessity of further combination of achievements of law, sociology, social psychology for the development of such direction as riskology. Interdisciplinary interrelations between natural, exact and humanitarian­social sciences could create a basis for the development of legal futurology. It is emphasized that the legal science is involved in the realization of several functions: rule­making (the principle of scientificity is envisaged as one of the bases of the rule­making process), ideological (legal ideology is the core of the ideo­ logy of the Belarusian state), upbringing and educational. The combination of these functions is of great importance for the state.

The textile industry still has serious problems in managing waste disposal that causes environmental pollution, including the batik factory industry. Many studies have been conducted to overcome ecological damage by reducing the levels of dyes contained in textile industry waste. Apart from textile industry waste, household waste, especially egg shells, is very high. One alternative method for processing batik factory liquid waste is by adsorption using biosorbent, which is considered cheaper and easier to obtain. An example of a biosorbent is an eggshell. This study includes the characterization of eggshells activated by NaOH and HCl for Indigosol Blue adsorption, morphological analysis of eggshells with SEM and EDS, wavelength determination, calibration curve, and adsorption capacity. The morphology of the eggshell shows a porous surface with high levels of calcium, oxygen, and carbon, indicating that the main compound forming the eggshell is CaCO3. The determination of maximum wavelength and adsorption capacity is done using the UV-Vis spectrophotometry method. The maximum wavelength is 530 nanometers, and an R2 value of 0.9596 was obtained from the regression curve equation. Characterization according to SNI eggshell before activation water content: 0.34%, ash content: 0.25%, iodine absorption: 326.552mg/gram and after activation with NaOH water content is 1.34%, ash content: 0.39%, iodine absorption: 403.015mg/gram. The optimal concentration of processed egg shells for indigosol blue adsorbent is 2% egg shells, the largest in this study as an adsorbent. It turns out that adsorption is still ongoing. The optimum type of activator for Indigosol Blue absorption is 100Mesh dry eggshell powder from NaOH activation.

The purpose of this study was to find out the physicochemical characteristics of baked egg custard adding 1%, 2%, and 3% of suji leaf juice with a control sample that had no addition. Four treatments and five replications were used in a fully randomized design. Standard laboratory techniques were used to examine the following: texture, pH, yield, color (L, a*, b*), proximate composition, and crude fiber. Data of baked egg custard were processed using ANOVA and Duncan's Multiple Range Test to identify significant differences. The addition of suji leaf juice had a substantial impact on all measured parameters, according to the results (P<0.01). In terms of protein, fat, and crude fiber content, as well as improved texture and color qualities, the custard made with 3% suji leaf juice was highest quality.  Improved product stability and sensory appeal were also demonstrated by the pH, yield, and moisture content. According to the results, suji leaf juice optimally improves the physicochemical quality of baked egg custard when added at a rate of 3%. This makes it a promising ingredient for dessert goods that are both functional and aesthetically pleasing.

Resumo
Prospective primary school teachers’ mathematical knowledge of sampling
Authors: Stuardo-Aguayo Alondra , Gea María Magdalena , Begué Nuria , Batanero Carmen
Published: January 2025

Sampling is a fundamental stochastic concept that bridges statistics and probability. Due to its importance, some elementary sampling ideas have been included in the latest Spanish primary education decrees; however, teachers may not be familiar with the topic, and research on the sampling knowledge of teachers is scarce. To fill this gap, the aim of this study was to assess common and advanced mathematical knowledge of sampling of 105 prospective primary school teachers by analyzing their responses to a questionnaire with open-ended questions. Common content knowledge was assessed by asking for definitions and examples of sample and population and by discriminating between correct and incorrect sampling methods. Advanced knowledge was tested by asking for an estimation of the population mean from the sample mean and of the population and proportion in a new sample from the sample proportion. Results indicated better common content knowledge than previous studies and gaps in advanced knowledge. Most participants had a multi-structural understanding of sampling concepts, where several aspects were described but not related to each other. We conclude that there is a need for better preparation of prospective primary school teachers’ sampling knowledge considering the current curricular deepening on this topic, and new research should be oriented toward designing and evaluating related teaching actions.
Modelo de gobernanza ante eventos disruptivos en la Universidad de Costa Rica
Authors: Montero Sánchez Álvaro , Medina Arias Kattia , Rodriguez Gutiérrez Johnny
Published: January 2025

Este artículo aborda la gobernanza ante eventos disruptivos en la Universidad de Costa Rica (UCR) a partir de la propuesta de un modelo que se creó considerando los resultados de un proyecto de investigación desarrollado en el año 2023 en todas las sedes y recintos institucionales. El objetivo de la investigación fue proponer un sistema de gobierno y gobernanza para que la UCR enfrente los impactos de los eventos adversos o disruptivos de forma coherente y articulada, tanto en sus sedes y recintos como con el Sistema Nacional de Gestión del Riesgo. Se trató de una investigación cualitativa y exploratoria, utilizando una muestra no probabilística por conveniencia. Como instrumentos de recolección de datos se desarrollaron grupos focales con los consejos asesores, entrevistas semiestructuradas y revisión documental. Mediante la aplicación de estos instrumentos, se logró identificar que existe una visión institucional centralista para la atención de eventos disruptivos, lo que genera que las sedes y recintos dependan de las decisiones que se toman a nivel de autoridades universitarias superiores, dejando de lado la autoridad a nivel local. Se evidenciaron dificultades en el flujo de información entre las autoridades de la sede central y la sede o recinto en el cual se está presentando la situación, lo que interfiere de manera negativa en el manejo de la crisis por parte de las autoridades locales. Se concluye que la implementación de lineamientos para la atención de eventos disruptivos no solo fortalece la resiliencia institucional ante situaciones de riesgo, sino que también pretende asegurar la continuidad de los servicios esenciales que se brinda en la institución.
