Brechas digitales: el reto de las nuevas tecnologías para los derechos humanos
Authors: Casadei Thomas
Published: January 2025

La brecha digital es una cuestión social que afecta la relación entre tecnología y democracia, generando exclusión y desigualdades no solo en el acceso a dispositivos, sino también en las habilidades para usarlos. Los estudios sobre esta problemática subrayan la importancia de analizar los resultados derivados de un acceso desigual a la red, como la frecuencia de uso y los tipos de actividades realizadas. Las estrategias para reducir la brecha digital se enfocan en dos áreas principales: el apoyo económico y la educación inclusiva. En este sentido, la brecha digital se considera un reflejo de pobreza y vulneración de derechos, impulsando la necesidad de garantizar el derecho de acceso a la red y a la alfabetización digital, como plantea la «Carta de Derechos Digitales» en España desde 2021.

Psychopathy: Criminality Interface
Authors: J. P. Pramod
Published: January 2025

Psychopathy emphasizes its intention in understanding deviant conduct. It explores the imbrication between
psychopathy and anti–social actions, where traits similar to impulsivity and casualness for societal morals participate. It delves
into the broader realm of felonious behaviour, examining how psychopathic traits contribute to the commission of colourful
offences, ranging from white-collar crimes to violent acts. This paper examines the intricate connections among psychopathy,
anti-social behaviour and felonious acts probing into the interplay of these constructs within the environment of psychology and
criminality. Psychopathy, characterized by traits similar to callousness, superficial charm and lack of empathy has been
associated with increased propensities for engaging in both anti–social and felonious acts. The present paper is a sapience into
the thematic understanding of the Psychopathy- Criminality interface.
A hierarchy of semidefinite programs for generalised Einstein-Podolsky-Rosen scenarios
Authors: Hoban Matty J. , Drescher Tom , Sainz Ana Belén
Published: January 2025

Correlations in Einstein-Podolsky-Rosen (EPR) scenarios, captured by assemblages of unnormalised quantum states, have recently caught the attention of the community, both from a foundational and an information-theoretic perspective. The set of quantum-realisable assemblages, or abbreviated to quantum assemblages, are those that arise from multiple parties performing local measurements on a shared quantum system. In general, deciding whether or not a given assemblage is a quantum assemblage, i.e. membership of the set of quantum assemblages, is a hard problem, and not always solvable. In this paper we introduce a hierarchy of tests where each level either determines non-membership of the set of quantum assemblages or is inconclusive. The higher the level of the hierarchy the better one can determine non-membership, and this hierarchy converges to a particular set of assemblages. Furthermore, this set to which it converges contains the quantum assemblages. Each test in the hierarchy is formulated as a semidefinite program. This hierarchy allows one to upper bound the quantum violation of a steering inequality and the quantum advantage provided by quantum EPR assemblages in a communication or information-processing task.
Protesta, violencia y participación política en Colombia. La perspectiva multidimensional de la protesta social
Authors: García Sarria Juan José , Ramírez Motoa Camilo , González Cortés Armando , Saavedra Cardoso Erwin Alejandro
Published: January 2025

En el panorama nacional de los últimos 30 años, las protestas sociales han constituido una de las herramientas de participación política más efectivas a la hora de poner de manifiesto las necesidades e intereses de la población colombiana. Este apuntalamiento de la protesta en el escenario político coincide con una creciente preocupación por parte del Estado y de la fuerza pública por garantizar los derechos fundamentales de los ciudadanos y, a su vez, preservar el orden y la seguridad. Con este propósito en mente, la presente investigación tiene como objetivo diseñar un modelo integrado de formación policial que tomando en consideración la perspectiva multidimensional de la protesta social se alinee con los procesos de transformación y modernización con enfoque en derechos humanos de la Policía Nacional. Para esto, se adoptó una metodología mixta de tipo exploratoria y correlacional. Se indagó por las perspectivas y juicios en torno a la protesta social y la actuación policial en una muestra compuesta por estudiantes universitarios, expertos académicos y personal policial. Los resultados de la investigación permiten establecer una compleja red de relaciones entre múltiples factores estructurales y proximales (económicos, políticos, culturales, situacionales e interaccionales). Se lograron identificar dos elementos determinantes en la forma en que las protestas evolucionan a manifestaciones violentas o se mantienen como expresiones pacíficas y políticas: intensificadores y pacificadores. Finalmente, con estos elementos se concretó la creación de una propuesta de modelo de análisis de la protesta social como insumo para el proceso de formación integral de uniformados de la Policía Nacional en donde se realza el respeto a los derechos humanos.

Preparar la fiesta: logística y gestión material en las juras y en las exequias reales en el Nuevo Reino de Granada (siglo XVIII)
Authors: Velasco Pedraza Julian Andrei
Published: January 2025

Las exequias y las proclamaciones de los reyes hispánicos fueron celebraciones fundamentales para la continuidad del poder en los territorios americanos. Principalmente, la historiografía ha abordado estos fenómenos desde sus dimensiones políticas, artísticas y simbólicas. No obstante, su organización y su sustento material son aspectos poco atendidos. Por tal razón, este artículo considera y analiza dichas fiestas desde su engranaje logístico y material como facetas esenciales, sin las cuales la representación simbólica del poder no hubiera sido posible. Se estudian las gestiones previas para planear y costear las festividades, la coordinación de personas e instituciones participantes en la ritualización de los eventos, así como la materialidad del arte efímero infaltable en el duelo y en la exaltación de los monarcas.

Authors: Dhuri Maithili Prashant , Joshi Mrunal , Sinha Ritu
Published: January 2025

Cement plays a crucial role in India’s infrastructure projects and contributes significantly to the nation’s gross domestic product (GDP) and employment. India’s urbanization relies heavily on this sector as the world’s second-largest producer of cement. Given its economic importance, understanding and assessing financial health and predicting the likelihood of default by these companies are critical for stakeholders. This study investigates various financial ratios, assesses their significance, and explores their relationship with the Altman Z score, a financial ratio used to predict the probability of a company’s bankruptcy. Recent corporate practices show a growing trend toward incorporating corporate social responsibility (CSR) reporting and sustainable growth rate (SGR) reporting into mandatory disclosures. These metrics are strategically used to improve public perception, build stakeholder trust, and convey a company’s reliability and operational performance. This study further explores the potential impact of CSR and SGR on bankruptcy risk, assessed using the Altman Z-score. Empirical analysis within the Indian cement industry reveals that, at present, CSR and SGR factors may not have a significant effect on financial distress. This study contributes significantly to the understanding of the financial health of the Indian cement industry while examining the evolving roles of CSR and SGR. It provides a nuanced perspective by empowering stakeholders to identify financial and non-financial indicators of stability. It also emphasizes the critical need for holistic assessment methodologies in the ever-evolving corporate landscape.
Educomunicación y apropiación de conocimiento científico: un análisis semiótico de la recodificación en museos de ciencias
Authors: Gómez Mendoza Yolanda
Published: January 2025

Este artículo presenta los principales hallazgos de un análisis de carácter semiótico efectuado en museos de ciencias, bajo la finalidad de entender cómo los procesos educomunicativos aportan a la apropiación del conocimiento científico, a través de una pormenorizada observación de la recodificación de dicho conocimiento que allí se lleva a cabo. El locus corresponde al Museo del Espacio en Bogotá y el Museo de Ciencias de La Plata (Argentina). El marco teórico-metodológico es la Teoría de los Códigos (Eco, 2000), y que, bajo el modelo de Narváez (2019), hace posible un análisis formal para reconocer las características de la función semiótica, establecida en forma de código. Los hallazgos evidencian una recodificación que estructuralmente conserva las características de la codificación peculiar del conocimiento científico. Desde esta perspectiva, la cultura científica, concebida como código, determina para la enculturación científica límites que son semióticos y no políticos. Así, fue posible elucidar el rol de los museos en apoyo a la alfabetización científica; sin que ello insinúe el reemplazo de la escuela en su función primaria. La significación queda supeditada a la manera en que el código produce enunciados inteligibles y, para ello, es sugerente la experiencia previa en el uso del código.
Financial Incentives, Income Supplementation, Cash Transfer, and Universal Basic Income Interventions in Diabetes: Understanding Differences and Effectiveness: A Scoping Review
Authors: Egede Leonard E. , Campbell Jennifer A. , Linde Sebastian , Walker Rebekah J.
Published: January 2025

The objective of this review is to evaluate and summarize the evidence base for the effects of monetary intervention approaches (the use of positive monetary reinforcers and gains) on diabetes outcomes. A reproducible search using OVID Medline, PubMed, Scopus, and CINAHL was conducted. Articles published from database creation up to July 2024 were searched. Outcomes included hemoglobin A1c (HbA1c), LDL, BMI, blood pressure, quality of life (QOL), psychosocial factors, self-care behaviors, and diabetes complications. A total of 13 articles met inclusion criteria and were included for final synthesis. Looking at the monetary approach across each study, eight used financial incentives, three used a form of income supplementation, one used cash transfers, and one used a combination of income supplementation and financial incentives. Ten of the 13 studies found statistically significant and clinically meaningful changes in HbA1c. For participants receiving interventions, change in HbA1c ranged from 0.19% to 1.74% for interventions incorporating financial incentives, 0.7% to 1.3% for interventions incorporating income supplementation, and 0.2% to 0.7% for the study incorporating cash transfers. Overall, evidence supports the relationship between monetary approaches, diabetes-related outcomes, and self-care behaviors across monetary approaches. Future studies should consider comparison between different monetary approaches using designs that will allow identification of effective strategies. As these approaches are theoretically and structurally different, pathways identifying the underlying mechanisms of change are greatly needed to advance the field.

Authors: Patidar Vardhan , Bhargava Ashish
Published: January 2025

The integration of renewable energy sources, such as solar and wind, into modern power grids presents challenges in maintaining power quality and stability, particularly under fault conditions like voltage sags and swells. This research focuses on the design and optimization of Dynamic Voltage Restorers (DVRs) to enhance power quality and Fault Ride through (FRT) capabilities in hybrid solar-wind systems. Using advanced control strategies, including fuzzy logic and adaptive Bee Colony Optimization (ABCO), DVRs mitigate voltage disturbances and optimize the parameters of Proportional-Integral (PI) controllers. The study examines system performance across three scenarios: without DVR, with DVR using fuzzy logic control, and with DVR employing ABCO. Results demonstrate progressive improvements in voltage stability, power quality, and total harmonic distortion (THD) reduction, establishing DVRs as critical components for integrating renewable energy sources into reliable and resilient grid systems
Hybrid Adaptive Filtering Approaches for Lithium-Ion Battery State of Charge and Health Estimation
Authors: Yogesh Anil Jadhav , Bhargava Ashish
Published: January 2025

Approach to a hybrid algorithm that would combine Recurrent Neural Networks, Kalman Filters, and estimates the State of Charge and Health of lithium-ion batteries. Normally, the established methods fail while dealing with their non-linear characteristics and dynamic operation, thus sometimes giving erroneous predictions. The proposed Hybrid Kalman Filter (HKF) combines strengths of RNNs and Kalman filters. RNNs are used as they can well model complex temporal dependencies and non-linear relationships in the battery data that improve the Kalman filter prediction capabilities. This algorithm works under two main stages: training the RNN on historical data with the goal to learn the battery dynamics and exploit these insights in real-time estimation of SOC and SOH. The experimental validation also proved that the HKF performs superiorly than other conventional methods such as UKF, especially concerning the lower values of RMSE achieved under changing conditions of C-rate (slow and fast charge/discharge rates). This is what ensures the efficient management of a battery in better performance, safety, and durability. It does have great promise for use in electric vehicles, renewable energy systems, and portable electronics where accurate battery monitoring is important to ensure reliable and efficient operation.

The concept of mindful parenting, derived from the broader framework of mindfulness, has gained increasing recognition in Indonesian parenting practices over recent years. However, the Interpersonal Mindfulness in Parenting (IM-P) instrument, which possesses strong psychometric properties, has not yet been available in Bahasa. The purpose of this study is to adapt the IM-P instrument into a valid and reliable Indonesian version. The IM-P was translated and adapted into Indonesian, involving a sample of 735 parents (M = 36.63; SD = 7.354) with children aged 3 to 17 years. Using a random sampling procedure, the first sample (n = 367) was used for Exploratory Factor Analysis (EFA), while the second sample (n = 368) was used for Confirmatory Factor Analysis (CFA). The study revealed that the Indonesian version of the IM-P consists of 20 items and 4 dimensions: Emotional Awareness of Self and Child, Self-Regulation in Parenting, Non-judgmental and Compassion for Child, and Non-judgmental and Compassion for Self. Overall, the IM-P Indonesia demonstrated good reliability. Additionally, the IM-P Indonesia showed a significant negative correlation with parenting stress, except for the dimension of Non-judgmental and Compassion for Self. These findings suggest that the IM-P is a valid and reliable measure for use within the Indonesian population.

Keberadaan seorang pemimpin yang disebut Chief Executive Officer (CEO) memiliki tanggung jawab yang besar dan memainkan peran penting dalam pengambilan keputusan strategis perusahaan. Penelitian ini bertujuan menguji pengaruh CEO characteristics dan intellectual capital terhadap kinerja perusahaan dengan menggunakan seluruh perusahaan yang terdaftar di Bursa Efek Indonesia tahun 2014-2028 dan menggunakan metode purposive sampling. Teknik analisis yang digunakan adalah analisis regresi linier berganda. Hasil penelitian menunjukkan bahwa CEO Age dan CEO Gender berpengaruh negatif dan signifikan terhadap kinerja perusahaan. CEO yang lebih tua cenderung berhati-hati dan menghindari risiko. Ketika mengambil risiko yang lebih rendah maka hasil yang akan didapat akan lebih rendah. Perbedaan psikologis antara pria dan wanita memiliki konsekuensi besar pada tata kelola perusahaan. Wanita memiliki persepsi yang berbeda tentang peran kepemimpinan yang biasanya lebih memperhatikan kepentingan pemangku kepentingan. CEO Education berpengaruh positif dan signifikan terhadap kinerja perusahaan. CEO dengan tingkat pendidikan yang lebih tinggi, cenderung memiliki pengetahuan yang lebih luas dan keterampilan analitis yang lebih baik. Hal ini memainkan peran penting dalam pengambilan keputusan strategis dan manajemen keuangan, yang dapat meningkatkan kinerja perusahaan. CEO tenure dan intellectual capital tidak berpengaruh signifikan terhadap kinerja perusahaan. CEO dengan masa jabatan yang panjang kemungkinan masih dalam comfort zone. Kinerja perusahaan tidak dipengaruhi oleh masa jabatan CEO karena dengan masa jabatan yang lama maupun pendek memiliki tugas dan tanggung jawab yang sama untuk mengelola kinerja perusahaan. Perusahaan dari industri berbeda memiliki jangkauan yang berbeda pada aset dan peluang dalam mengoperasikan bisnisnya dengan efektif, sehingga perusahaan membutuhkan lebih dari sekedar aset tetap (berwujud).

The aim of the present study is to develop a foreign language teaching responsibility perception scale for pre-service foreign language teachers. While teacher responsibilities are discussed by many stakeholders, it was identified that there is no scale in the literature on what pre-service foreign language teachers feel responsible for. Following the literature review, the form developed was finalised by making the necessary arrangements after the opinions of the experts for content validity. The researchers administered the scale in printed form to 354 participants who were studying in the 3rd and 4th grades in the Foreign Language Education departments of the Faculties of Education in Ankara. Exploratory Factor Analysis (EFA) was applied for the construct validity of the scale. As a result of EFA, a three-factor structure was determined, consisting of 29 items in total: 15 items in the first factor, 7 items in the second factor, and 7 items in the third factor. The total eigenvalue of the scale was calculated as 51,529%. Cronbach Alpha value was calculated for reliability. While the Cronbach Alpha value of the scale was calculated as 0.904, the Cronbach Alpha values of the factors were calculated as 0.920; 0.858; 0.854 respectively. Item-total correlations and comparisons between upper and lower groups showed that all items in the scale were discriminative. In the light of the validity and reliability analysis results, it can be said that a measurement tool with the necessary psychometric properties was developed within the scope of the current study.
