Public value in the making of automated and datafied welfare futures
Authors: Allhutter Doris , Alushi Anila , Cavalcanti de Alcântara Rafaela , Männiste Maris , Pentzold Christian , Sosnowski Sebastian
Published: October 2024

Across Europe, the public sector is expanding its efforts to introduce data-driven decision-support and intelligent systems in the administration of welfare. The growing body of research that highlights the impact and harms these systems have on citizens’ lives, raises questions about the guiding ideas, values, and norms that are at the heart of current transformations in welfare. Research in critical data studies contends a silent marketisation of social protection and governance. It implies an intricate entanglement between the procedures and output of service provision on the one hand and the normative outcomes in terms of the well-being and flourishing of society as a whole on the other hand. Thinking with the capabilities approach and buen vivir as well as with the concept of data justice, our paper asks how to conceptualise this relation. It discusses how (in)justice may become a sociomaterial component in automated welfare and emphasises that welfare outcomes and welfare practices, including their procedural aspects, are rather co-produced than just interdependent. We conclude that whether future infrastructures of welfare will create public value or not, depends on the institutional arrangements, policies, and norms built to distribute the emerging benefits and risks equally in society.
Accountability protocols? On-chain dynamics in blockchain governance
Authors: Nabben Kelsie , De Filippi Primavera
Published: October 2024

Accountability refers to a relationship of responsibility, answerability, and enforceability between individuals and groups. In contrast to traditional institutions that rely on enforcement of accountability through traditional legal frameworks, blockchain systems rely on the “rule of code”, i.e. the operation, governance, and transactions on a blockchain are governed by pre-written, transparent, and immutable rules that are expressed in software code. By empirically examining the case of the Ethereum blockchain and the Lido “liquid” staking services protocol, this paper analyses the formalisation of accountability mechanisms between protocols to ensure that Lido’s proportionate share of staked ETH on the network does not pose a risk to the security and stability of Ethereum. The findings of this paper are threefold: (1) accountability on a blockchain is achieved through the implementation of checks and balances institutionalised via technological protocols ("on-chain accountability"); (2) accountability requires trade-offs, meaning that giving accountability to one type of stakeholders might actually reduce the accountability of the system for another category of stakeholder; and (3) end users of the blockchain are consumers of accountability, rather than influential participants in producing it. This research underscores the complex interplay of technical and governance considerations in ensuring accountability within blockchain systems, offering insights into the broader implications of on-chain accountability for stakeholders across blockchain ecosystems.
Three-layered films enable efficient passive radiation cooling of buildings
Authors: Guo Yi
Published: October 2024

To address the excessive energy consumption of building cooling, the coverage of passive radiation cooling materials on the surface of buildings can effectively save the global refrigeration power resources and reduce the greenhouse gas emissions generated by refrigeration equipment. In this work, passive radiation hydrophobic fabric cooling materials with three functional layers (i.e., top polydimethylsiloxane [PDMS] film layer for solar emissivity, middle polymethylmethacrylate [PMMA] film layer for solar reflectivity, and bottom cotton fabric layer for support) were prepared. This passive radiation cooling material with optimized thickness of PDMS (1.5 mm) and PMMA (3.5 mm) have a rich uneven filament structure and ideal internal bonding structure, which enabled 94% of solar reflectivity and 93.4% of atmospheric window emissivity (8–14 μm). Top layer of the composite film was hydrophobic (a contact angle of 117°) and allowed the rolling of water droplets to remove most of the surface dust. Moreover, these composites presented an excellent cooling of 7.7–15.0°C in the outdoor real cooling test. For medium-sized houses, the roof covered with composite was expected to reduce the emission CO2 by 17% every year. The findings of this work indicated that the prepared three-layered radiation cooling materials have great potentials in thermal energy storage buildings.
Formation mechanism and oil-bearing properties of gravity flow sand body of Chang 63 sub-member of Yanchang Formation in Huaqing area, Ordos Basin

Published: October 2024

Gravity flow sand body is an important reservoir for deep water deposition. The in-depth study of its formation mechanism and oil enrichment law can provide important guidance for oil and gas exploration in deep water areas. In this article, taking the deep-water gravity flow sand body of the Triassic Chang 63 sub-member in the Huaqing area as an example, the identification characteristics, formation mechanism, and oil-bearing characteristics of the gravity flow sand body are systematically discussed. The results show that sandy debris flow, turbidite flow, and mixed event flow present different superposition combination modes on vertical gravity flow deposition. The lithofacies of the gravity flow sandstone complex are mainly affected by lake level fluctuation, provenance supply, and hydrodynamic conditions. According to the formation conditions, sedimentary types. and distribution characteristics of deep water gravity flow sand bodies, a three-dimensional sedimentary mode of deep water gravity flow sand bodies is established. It is found that the physical and oil-bearing properties of the sandy debris flow sand body are better than those of the turbidity flow sand body. The reason is that the proportion of debris in the sand body of sandy debris flow is high, and the content of debris particles is generally greater than 70% according to the statistics of thin sections, which is conducive to the formation of pores. Second, sandy debris flow belongs to block transport, and the mixing of lithology is not sufficient in the process of block flow transport, so some pores will be preserved. Finally, gravity flows, which are dense at the beginning, become less dense later as detrital sediments unload, allowing them to be transported to distant regions. Therefore, the monolayer thickness of the sandy debris flow sand body is large (generally greater than 0.5 m), and the particle size of the debris ranges from 0.03 to 0.3 mm. Finally, the physical and oil-bearing properties of the sandy clastic flow sand body are better than those of the turbidity flow sand body.
Diagenesis of marine-continental transitional shale from the Upper Permian Longtan Formation in southern Sichuan Basin, China
Authors: Yu Yu , Deng Xiaoliang , Deng Yuwei
Published: October 2024

Upper Permian Longtan Formation transitional shale has become an important exploration layer, but the Longtan Formation shale (LFS) has a complex mineralogical composition, which affects the subsequent diagenesis and diagenetic evolution, and restricts the subsequent geologic exploration of shale gas. In this article, the observation of drilling cores, argon ion polishing-scanning electron microscope, Vitrinite reflectance, and X-ray diffractometer were used to analyze the type and characteristics of diagenesis of the LFS and clarify the stage of diagenetic evolution. The results show that the main diagenesis in the LFS is compaction, cementation, thermal maturation of organic matter (OM), dissolution, and transform of clay minerals. Among them, OM hydrocarbon generation, clay mineral transformation, and dissolution are pore-enhancing diagenetic events. Compaction and cementation are pore-reducing diagenetic events. The transitional and marine shales have similar characteristics of diagenesis, but there are big variations in the diagenesis of OM hydrocarbon, authigenic quartz, and siderite. The complex depositional environments of the marine-continental transition environment have resulted in a variety of rock types, which in turn influenced the diagenesis types and diagenetic evolution process. Compared with the transitional shales of the Shanxi and Taiyuan formations in the South China North Basin, the LFS are characterized by high clay content, low quartz content, complex mineral compositions, and a higher degree of thermal evolution.
Vertical high-velocity structures and seismic activity in western Shandong Rise, China: Case study inspired by double-difference seismic tomography
Authors: Zhang Zhengshuai , Zheng Jianchang , Yin Di , Li Bo , Guo Yuqin , Chai Guangbin , Wu Jing , Wu Yang
Published: October 2024

In this article, we collected the seismic phase arrival data (115°–120°E, 34°–39°N) of 2,833 local natural earthquakes above magnitude 1.0 recorded by 128 seismograph stations provided by the China Earthquake Networks Center covering the period from January 2008 to October 2023. We extracted the first arrival P- and S-wave arrival time data and obtained 26,351 P- and 26,349 S-wave absolute arrival times and 99,627 P-differential and 99,625 S-differential arrival times. Then, we determined 3-D P and S wave velocity structures under the Luxi region by using the double-difference tomography method. The results show lateral heterogeneities under the Luxi region, and the distribution of surface basins and uplift zones is associated with seismic velocities within the crust. The vertical section shows the widespread presence of vertical high-velocity bodies within the crust of the Luxi region, indicating seismological evidence of mantle upwelling in the region. Meanwhile, our imaging results also clearly indicate the presence of a significant low-velocity anomaly at depths of 13–17 km, which corresponds to the presence of a high-conductivity layer at that depth obtained from electromagnetic bathymetry. The transition zone between high and low velocities exists at a depth of 7–13 km, which plays an important role in the transfer of lithospheric stresses from the deep to the shallow part of the lithosphere. Combined with the results of the previous deep seismic wave velocity structure, petrology, and geological investigations, the deep dynamical background of the formation of slip tectonics and seismic mechanism in the Luxi area can be attributed to the go-slip activity of the Tan-Lu fault Zone, the subduction of the Pacific Plate, and the magmatism generated by mantle upwelling.
Meillassoux and Heidegger – How to Deal with Things-in-Themselves?
Authors: Leidlmair Karl
Published: October 2024

In his critique of post-Kantian philosophy, Meillassoux expresses considerable doubts as to how it is capable of describing a world independent of man. He places Heidegger among the ranks of thinkers who are caught in the same trap of the thought-world circle. In this article, I will first examine which complex indirect proof Meillassoux uses to find a path towards an independent reality. In the next step, I will discuss where Heidegger locates Beings in themselves against the backdrop of the Dasein-Being correlation. A radical change of perspective on what it means to be a thinking and understanding “subject” is proposed in this context. In contrast to Meillassoux, an appropriate interpretation of Heidegger’s Dasein can show that there is no need for an indirect proof of a real outside of the correlation. The decisive question is how Heidegger’s correlation of Dasein and Being can be reconciled with statements about the ancestral or whether it stands in implacable opposition to such statements.

Published: October 2024

Desde hace más de 30 años, la problemática socioambiental del territorio de la subcuenca Río La Sabana-Laguna de Tres Palos ha sido ampliamente estudiada; sin embargo, los problemas en la zona continúan insolutos. El objetivo de este artículo fue analizar el papel que gobierno, sociedad y academia han tenido en la coproducción de conocimiento orientado a solucionar la problemática socioambiental del territorio. El enfoque fue cualitativo, donde se utilizó la técnica de la entrevista a profundidad y análisis etnográficos; la información recabada se examinó a través del software Atlas.Ti. Los resultados mostraron que las formas de construcción de conocimiento se fundamentan en saberes verticales poco participativos, dirigidos a cubrir necesidades políticas coyunturales, pero no hacia un planteamiento inclusivo de los actores locales. Concluimos que existen condiciones sociopolíticas robustecidas históricamente que han obstaculizado los procesos de coproducción de conocimiento y cogestión ciudadana, académica y política, para solucionar la problemática socioambiental en el territorio.

Published: October 2024

In order to address the current deficit in research on discrete elements within the context of the cotton seed pressing process, a combination of physical tests and simulation experiments were conducted on Xinluzao 84 cottonseed. The Plackett-Burman experimental design was employed to identify the parameters that had a significant impact on the accumulation angle. Subsequently, the Box-Behnken design was employed to establish a second-order regression model for the accumulation angle and the significant parameters. This resulted in the optimal parameter combination for the maximum friction coefficient, minimum sliding friction coefficient and critical shear stress being 0.207, 0.388, and 5×10⁶ Pa, respectively. In order to calibrate the cottonseed bonding parameters, a Box-Behnken test was designed based on the results of the cottonseed particle crushing test. The optimal parameter combinations of normal stiffness, tangential stiffness, and bond radius were obtained as 1.25×10⁹ N/m², 7.57×10⁸ N/m², and 0.727 mm, respectively. The obtained parameters were verified by the simulation of stacking angle and the crushing test simulation. The relative error was 0.84% and 0.46%, respectively. This serves to validate the cottonseed bonding model and simulation parameters, thereby providing a foundation for optimising the core structural parameters of the cottonseed shelling machine.
Recyclability of wastepaper containing cellulose nanofibers
Authors: Najideh Robab , Rahmaninia Mehdi , Khosravani Amir
Published: October 2024

Cellulosic/lignocellulosic nanofibers (CNF/LCNF) are value-added products which recently have been considered widely. This study focused on valorization of waste by making CNF from white cutting wastepaper (WCW), which was confirmed by the transmission electron microscope images. The CNF present in the paper recycling process showed significant effects on the final product and process aspects. Addition of 5% CNF (based on dry weight of pulp) to the recycled fibers improved the strength properties as well as the fines retention. But in contrast, the drainage decreased from 303 to 188 mL CSF. Finally, considering the importance of wastepaper history on the quality of recycling process and final products, as a new vision, this study focused on recyclability of wastepaper which has experienced CNF as an additive in their history of papermaking. In this respect, the papers reinforced with nanofibers in their history, after several recycling, experienced less reduction in the tensile and tear indices and fines retention. In summary, it seems that the presence of CNF in the wastepaper can slow down the reduction of product density and process properties during several recycling cycles and so restore their potential for subsequent papermaking cycles.
Analysis of wettability and contact angle of sodium bicarbonate impregnated wooden surfaces
Authors: Bayraktar Dursun Kemal , Güneş Mehmet , Çakır Musa Faruk
Published: October 2024

Scots pine and spruce wood samples were vacuum impregnated with 3, 5, and 9% sodium bicarbonate solution. Contact angle measurements were made by dropping 0.05 mL of pure water and 3% saltwater solution onto the material’s surface. The surface roughness of each sample was measured, and that of Scots pine control samples was higher than that of spruce samples, but the surface roughness values of spruce wood were higher in the samples impregnated with sodium bicarbonate. When pure water or saltwater solution was dropped onto the samples, it was observed that as the waiting times increased, the contact angle value decreased, the droplet height decreased, and the droplet width increased. It was found that the contact angles were higher in the control samples of both tree species than in the samples of 5% and 7%. The contact angles of 9% impregnation solution, pure water, and salt water were higher than the control samples. As the solution ratio increased on the surfaces impregnated with sodium bicarbonate, the contact angle also increased, and the wettability behavior decreased accordingly. Sodium bicarbonate solution is effectively used in the impregnation process for pine and fir woods, making the materials more resistant to water under outdoor conditions. This solution significantly reduces the risk of deformation of wood by increasing the contact angle and reducing its water absorption properties.

Trade in Lithuania under Rule of the Nazis
Authors: Braslauskas Justinas
Published: October 2024

Trade organisation in Lithuania during occupation by the Nazis was stimulated not by the country's local economy development but by an exterior factor - the intention of Germany, the aggressor state, to gradually integrate the local economy into its own economy. It was obviously demonstrated by the establishment of German companies in the region as well as by giving most of the wholesale and larger-scale retail businesses at those companies' disposal. In spite of the fact that it was permitted to re-privatise the smaller retail businesses which had been nationalised by the Soviet power, both retail and wholesale trade in Lithuania during the Nazis' occupation was moribund due to the scarcity of goods and transport and unworkable wage and price policy. In comparison with 1941, the number of retailers decreased by one fourth. In the region, the illegal and barter trade became especially widespread. The policy of subjugation of Lithuania's trade to the needs of the Reich was softened by the Lithuanian administration that was left to function alongside the German occupying civil authorities. Only on the initiative of officers of this administration were there new trade schools founded, various training and refresher courses for traders organised.
The Hostage in the Law of the Grand Duchy of Lithuania up to the First Lithuanian Statute (1529)

Published: October 2024

The hostage institution in the Law of the Grand Duchy of Lithuania has got an exhaustive historiography, that's why the manifestation of this institution in the earliest written source of GDL and the regulation of its standards up to the First Lithuanian Statute is discussed in this article.The information about the hostage up to the middle of the 15th century is fragmentary (the exception is the privilege of Duke Vytautas to the Brasta Jewish community in 1388). However, in the 2nd half of the 15th century - the beginning of the 16th century, the acts of the Lithuanian Metrica and other acts allow us to disclose the essence of the hostage, the object and the subject of the hostage law, the continuation, the procedure of return of the hostage, and so on.The First Lithuanian Statute legalized the main standards of the hostage law, though they were reflected in a many-sided way in court practice.

Розглянуто ефекти нелiнiйного впливу намагнiчування та магнiтного фазового переходу на стiйкiсть та динамiку маятника, виготовленого з магнiтом’якого феромагнетика, який має форму балки, поздовжнiй розмiр якої набагато бiльший за її поперечнi розмiри. Показано, що намагнiчування маятника впливає на стiйкiсть та може призвести до критичної змiни рiвноваги маятника в перпендикулярному (поперечному) до маятника магнiтному полi. В критичному полi вiдбувається втрата жорсткостi коливальної системи, а частота власних механiчних коливань маятника прямує до нуля. Критичний характер впливу магнiтного поля на маятник пов’язаний iз iндукованим магнiтним полем орiєнтацiйним магнiтним фазовим переходом у феромагнетику маятника, який супроводжується змiною симетрiї його магнiтного стану. Змiнне магнiтне поле, додане до стацiонарного магнiтного поля, iндукує вимушенi механiчнi коливання маятника за умови, що стацiонарне поле бiльше за порогову величину. Коли стацiонарне поле менше вiд критичного, то змiнне магнiтне поле може спричинити параметричний резонанс механiчних коливань маятника.

This study aims to comparatively analyze children's communicative behaviors based on the language (Korean or English) used by their mothers during the mother-child interactive play task. Twelve children aged 19 to 31 months participated. The play task included a free play phase (1 minute), first Korean play phase (3 minutes), English play phase (3 minutes), and a second Korean play phase (3 minutes). Mothers completed pre- and post-experiment questionnaires. The Wilcoxon signed-rank test examined differences in children's communicative initiations, breakdowns, response rates, and communication forms depending on the language used. No significant differences in communicative initiations were found across phases. Communicative breakdowns were significantly higher during the English phase compared to the second Korean phase. Response rates and languagebased communication were significantly higher in the Korean phases. Most mothers reported varied communication styles and discomfort during the English phase. The study demonstrates that children's communicative behaviors vary with the language used by their mothers, emphasizing the importance of using a mother's native language for effective communication and development.
Awareness on Accreditation of Diploma Engineering Programmes
Authors:   Professor & Dean Academics and Research, NITTTR, Shamla Hills, Bhopal, Madhya Pradesh - 462002, India, Gupta B L
Published: October 2024

Background: The provision of graded accreditation and autonomy of colleges has been made in the national education policy (NEP) 2020 which will be applicable for all types of higher education institutions in the country. The authors have noticed that there are very few diploma engineering programmes having accreditation and that too will expire for the majority of the programmes in June 2022. Purpose: To ascertain the awareness of faculty members on the accreditation process was the main purpose of the study. Apart from it, reasons for a very low number of programme accreditation were inferred and suggestions are made for the national board of accreditation (NBA), state government and polytechnics to improve and innovate the quality of diploma engineering programmes to satisfy the future needs of students, employers and society and implement the provisions of NEP 2020. Method: A descriptive research study was undertaken using the structured and semi-structured instrument designed by the researchers. The responses were collected from 525 principals, heads of departments and faculty members of the polytechnics of the country using Google Form. Results: It is found that on 95 parameters of the accreditation process the cumulative weighted mean level of awareness of faculty members is more than 60 percent. That clearly indicates that teachers are having in-depth awareness ofthe requirements of the accreditation process but they are achieving the minimum expectable level on various pre-qualifiers, criteria and sub-criteria because of various reasons. Conclusions: There is a number of other reasons which are abstracting the polytechnic and programmes to qualify for the accreditation. These reasons should be identified and addressed using well-designed quality improvement and innovation interventions at state, polytechnic and faculty members levels.

Background: Systematic collection of scientific evidence on the applicability an usability of model and its components is an important aspect of design and development research. Purpose: The aim of this study is to determine external validity of the organic reaction teaching model in terms of its practicability and potentiality in enhancing students’ performance scores. Method: A field testing method was conducted across five matriculation colleges in Malaysia by five (5) experts’ chemistry lectures who implemented a lesson plan developed based on the model’s constructs and then responded to an open ended questionnaire to express their views on the practicability of the model. 40 matriculation Students that participated in the field testing were also evaluated to determine the potentiality of the model on their performance in organic reactions. Four main themes having of many codes and quotations were identified. Results: The analysis of the results indicates that the model is compatible, clear and flexible for teaching organic reactions. Moreover, the model components have the potential of miximizing students’ academic performance in organic reaction with an overall score of 84.4 % in the organic chemistry tests. Thus, the model was found practicable for teaching and have the potential to minimized students’ common errors in organic reaction mechanisms. Conclusions: The findings of this study may similarly work as a reference model in developing modules and measuring instruments to reduce errors in other procedural concepts in chemistry and other science-related subjects.

Published: October 2024

Background: This paper addresses librarian-faculty collaboration in higher education, with a specific focus on electronic resources. Key challenges identified include poor communication, time constraints, and lack of institutional support. The study underscores the significance of collaboration in developing and managing academic resources, especially given the increasing reliance on digital collections. Purpose: The primary goal of the study is to explore ways to enhance teamwork between librarians and professors to improve the use and development of electronic resources. It aims to identify existing collaboration patterns, obstacles hindering effective partnerships, and the institutional support mechanisms that can foster better collaboration. Methods: A quantitative approach was used, employing a cross-sectional survey methodology with 178 participants (89 male and 89 females) from various higher education institutions. The structured survey, utilizing a 5-point Likert scale, measured attitudes, perceptions, and the frequency of collaboration in areas such as curriculum alignment, resource selection, and digital resource management. Results: The results reveal that both faculty and librarians recognize the importance of collaboration in resource selection and curriculum alignment. However, obstacles such as time constraints, lack of institutional support, and irregular communication hinder effective collaboration. Male participants showed greater interest in technical aspects, while females emphasized the importance of organized communication and digital resource management. Conclusions: The study concludes that improving librarian-faculty collaboration in electronic resource integration requires regular communication, enhanced institutional support, and proactive engagement in resource development. Targeted strategies are needed to strengthen partnerships, improve academic resources, and ultimately enhance academic program outcomes.

Published: October 2024

The refractive index during self-focusing was considered as a component of the metric tensor, it means, as a curvature of space-time. However, there was an interest – what will be, if the refractive index is complex. If we introduce a complex metric tensor, then the complex part will not curve space-time. At the same time, with the presence of nonlinear effects, damping modes will occur, it means, if n is linear, then the absorption will be α, but if n = n1 + n2I, then the absorption will be different, which will be discussed in this article.

Las organizaciones de desarrollo de software están adoptando el enfoque DevOps como una estrategia para mantenerse competitivas. El impacto de estas iniciativas se relaciona con la reducción del tiempo de desarrollo mientras se mantiene la calidad del software. Sin embargo, pocos trabajos han señalado específicamente que aspectos de la calidad se han medido. En este trabajo, presentamos los resultados de un mapeo sistemático de literatura en donde identificamos las características de calidad del producto de software que se han estudiado en entornos DevOps. Los resultados se complementan con las iniciativas de medición del desempeño general de DevOps y aquellas que miden la calidad del producto de software. Dada la falta de trabajos en esta área, como primer paso en la definición de un proceso de medición de la calidad del producto en entornos DevOps, identificamos algunas métricas de mantenibilidad y factores contextuales por considerar en estas iniciativas.

Este artículo se enfoca en la integración entre DevOps, que es un conjunto de prácticas que enfatiza la agilidad, la automatización y la colaboración entre los equipos de desarrollo y operaciones, y el perfil básico del estándar ISO/IEC 29110, que proporciona pautas para usar estándares de calidad y procesos de desarrollo de software en entidades muy pequeñas (EMPs). Esta investigación se enfoca en identificar la forma en las que los principios flexibles de DevOps pueden alinearse y, al mismo tiempo, reforzar las estructuras formales del ISO/IEC 29110. Para lograrlo, se evalúa hasta qué punto DevOps puede cumplir con los requisitos del ISO y garantizar que puedan mejorar la optimización de procesos, la mejora continua y la capacidad de ser dinámicos. Finalmente, se descubrirán elementos que servirían a las EMPs para mejorar su proceso de desarrollo y permanezcan conformes con los estándares internacionales.

La tarea de priorización de requisitos resulta crítica para realizar un correcto proceso de requisitos software, y dada su naturaleza altamente social, es menester tener claridad de los factores sociales y culturales que inciden en dicho proceso. El presente estudio tiene como objetivo elaborar un estado del arte sobre los factores sociales y culturales, así como las técnicas vinculadas con la tarea de priorización de requisitos en el contexto del desarrollo de software. Para ello se especificaron 4 preguntas de investigación que sirvieron para guiar una revisión sistemática de literatura con la que se seleccionaron y analizaron 54 estudios primarios obtenidos de cuatro Bases de Datos y un repositorio. Entre los hallazgos se encontraron cinco categorías de factores sociales y culturales: comunicación, entendimiento del dominio, entendimiento de los stakeholders, influencias culturales y sociales, y manejo de múltiples stakeholders; así mismo, entre las técnicas que consideran dichos factores se pudieron identificar tres categorías: centradas en el usuario, centradas en patrones y basadas en la negociación, siendo la primera categoría la que concentra el mayor número de técnicas encontradas.

Una de las etapas de la gestión de riesgos de ciberseguridad es el monitoreo y la revisión. Esta etapa forma parte del proceso de mejora continua de un sistema de gestión de riesgos de ciberseguridad. Este artículo tiene como objetivo llevar a cabo una exploración de una guía de auditoría de riesgos de ciberseguridad tomando como referencia objetivos comunes y guías de la auditoría de riesgos de ciberseguridad. Para ello se tomó como partida una Revisión Sistemática de Literatura (SLR) considerando los estudios de los últimos diez años (2012-2022), a partir de los cuales se identificaron 23 estudios que mencionaban objetivos y guías de auditoría de riesgos de ciberseguridad. Además, se propusieron atributos que deben ser considerados para la creación de un guía de riesgos de ciberseguridad. Posteriormente en el presente trabajo se define una guía de auditoría de riesgos de ciberseguridad (CRAG). Finalmente, se expone la aplicación de CRAG por medio de un caso de estudio considerando los parámetros identificados en los estudios previamente mencionados.

El uso de técnicas de Aprendizaje Automático (AA) en el área de la salud, específicamente en la identificación de enfermedades cardiovasculares (IEC), ha tenido un impacto significativo debido a la capacidad para analizar grandes cantidades de datos y extraer información relevante que puede ser esencial para la toma de decisiones médicas. Sin embargo, antes de ponerlos a disposición de los usuarios finales (médicos), se debe evaluar su capacidad para detectar sintomatologías relacionadas con enfermedades cardíacas utilizando puntos de referencia de conjuntos de datos en escenarios experimentales. Por lo tanto, es complicado determinar qué características utilizar en el proceso de evaluación y qué técnicas de ML son más adecuadas para la predicción de IEC. Este artículo presenta una revisión sistemática de la literatura sobre el procesamiento de conjuntos de datos basados en pruebas clínicas de enfermedades cardiovasculares y técnicas de AA. En este sentido, se realizó un análisis de las diferentes variables extraídas de publicaciones de revistas indexadas en bases de datos especializadas como Scopus, Web of Science, Science Direct, Biomed y Pubmed.

Este trabajo tiene como objetivo el desarrollo del prototipo de un sistema de posicionamiento que permita validar los modelos numéricos de predicción de aparición de residuos sólidos en las costas. Para ello, se ha realizado el diseño e implementación de un sistema de radiofrecuencia que permite el trazado de las trayectorias de boyas Lagrangianas. El sistema se compone de dos tipos de dispositivos: boyas de deriva superficial y receptores que permitan la extracción de los datos de las trayectorias de las boyas en tiempo real. Las boyas incorporan un receptor GNSS que registra su posición y se comunican con tecnología LoRa con un transceptor que se encuentre en su área de cobertura. Este sistema puede servir no sólo como herramienta de validación de modelos hidrodinámicos numéricos, también representa una metodología escalable, con amplio potencial de uso en el campo de la Oceanografía observacional.
