Authors: Onsomu Obed Nelson , Çetin Alper , Terciyanlı Erman , Yeşilata Bülent
Published: June 2024

Integration of renewable energy sources (RESs) into the grid has profoundly gained a lot of attention in the energy domain, coupled with an ever-changing generation profile and dependency on weather conditions, RESs are commonly known to pose security of supply challenges and in case they are not monitored they can cause techno-economic losses and even lead to catastrophic failure of the electrical grids. However, their availability and negligible generation cost make them environmentally friendly when compared to conventional energy sources. For seamless connection of renewables to the grid network, battery energy storage system (BESS) has been suggested in literature, the technology has come to the fore recently, and has found application cases in the utility grid with enhanced functions to participate in both reserve and wholesale electricity markets such as day-ahead and intra-day markets. This technical brief presents various energy storage systems (ESSs) potentially used in large-scale grid networks, which are investigated, and their individual properties are compared, where necessary application areas with examples enabled by constituting material properties are outlined, in the same context their general advantages and disadvantages are given in reference to the specific application cases. In addition, the application of large-scale BESS is explained together with the integration solutions such as use of Virtual Power Plant (VPP) and microgrid.
Acoustic performance of covering systems with metallic roof tiles: effect of damping layers on rain noise
Authors: Wittmann Gabriel , Heissler Rafael Ferreira , Oliveira Maria Fernanda
Published: June 2024

Weather events directly affect buildings, and despite buildings being composed of construction systems and elements with characteristics that determine the necessary structural safety, modifications can be made to meet other performance requirements. The degree of vulnerability of a building fundamentally depends on the characteristics of its envelope, and in the current context of climate change, alterations in rainfall patterns are one of the main consequences. Insulating rain noise from roofing systems is particularly important in buildings with large spans, as the greater distance between supports leads to less rigidity of the systems. This work aims to analyze the influence of damping layers on the acoustic performance of metallic tile covering systems during the action of artificial rain produced in a laboratory environment. The tests were carried out according to the parameters of ISO 10140, Parts 1, 3, and 5, in 12 different compositions of the roofing systems. For comparison purposes, 4 types of simple tiles were also tested. The results show that, in multilayer systems, filling with glass wool between two tiles is the most efficient, with results of LIA = 74 dB for the simple trapezoidal tile TP-30 and LIA = 52 dB for the system with glass wool and elastomeric tape.

Published: June 2024

La investigación mediante un enfoque cualitativo, basado en revisiones bibliográficas, se planteó como objetivo, identificar las posibles vulneraciones de los derechos laborales derivadas de la aplicación del Acuerdo Ministerial MDT-2020-286 en el ámbito laboral privado de la educación superior. En particular, se focalizó en la evaluación de la vulneración del derecho al descanso semanal establecido en dicho acuerdo ministerial, contrastándolo con los derechos y garantías laborales contemplados tanto en el Código de Trabajo como en la Constitución de la República del Ecuador (CRE), los cuales fundamentan los principios que rigen el Derecho Laboral. La investigación subraya la importancia del respeto al ordenamiento jurídico como un sistema coherente y lógico, donde se valore la jerarquía normativa y se apliquen los principios del derecho como herramientas de interpretación al momento de aplicar o excluir una normativa que pueda afectar o menoscabar derechos ya reconocidos. Las conclusiones de la investigación evidencian cómo la normativa jurídica puede generar conflictos entre sus disposiciones o con normativas de otros cuerpos legales. Sin embargo, también resalta que la misma normativa proporciona los mecanismos necesarios para resolver dichos conflictos, buscando así establecer un ordenamiento que no vulnere los derechos y que sea coherente en su aplicación.

Authors: Carrion Valle Milton John , Calero Larrea Esteban Mateo
Published: June 2024

El presente artículo académico tiene como objetivo analizar los desafíos y recursos en la protección de los derechos de los adultos mayores en el ámbito del arrendamiento, comparando la legislación de Ecuador y Estados Unidos. La problemática radica en la falta de protección específica para los adultos mayores en materia de inquilinato en Ecuador. Aunque cuentan con derechos reconocidos en otros ámbitos, como la Constitución y la Ley Orgánica de las Personas Adultas Mayores, la ausencia de beneficios y garantías legales específicas en el ámbito del arrendamiento ha llevado a la vulneración de derechos fundamentales, como el acceso a una vivienda digna. Esta carencia normativa deja a los adultos mayores en una posición de desventaja frente a posibles abusos por parte de arrendadores, sin mecanismos claros para proteger su estabilidad habitacional y su bienestar en el contexto del alquiler de viviendas. La metodología de esta investigación es de naturaleza cualitativa que emplea los métodos analíticos, exegético y de derecho comparado. El método analítico se utilizará para descomponer el tema en sus componentes clave. Por otro lado, el método exegético implicará una interpretación detallada y contextualizada de las leyes, regulaciones y disposiciones legales relevantes en cada país, permitiendo un análisis profundo de la legislación vigente relacionada con este tema. Finalmente, el método de derecho comparado se empleará para comparar y contrastar las disposiciones legales y las prácticas en ambas jurisdicciones, identificando similitudes, diferencias y posibles áreas de convergencia o divergencia en la protección de los derechos de los adultos mayores en el contexto del arrendamiento de viviendas.

Authors: Wang Ping , Zhang Hongji , Wu Yongchao , Yang Rui , Jiao Baozhen , Zhang Li , Yu Decai , Huang Binquan
Published: June 2024

Pentatricopeptide repeat genes are ubiquitous in eukaryotes with mitochondria, especially in higher terrestrial plants. As RNA modification proteins, PPR are indispensable in plant growth and development. However, many PPR genes in model plants and food crops have been researched, but few studies about potato PPR genes have been reported. This research systematically performed a genome-wide analysis of the potato PPR members and verified the gene expression and the protein subcellular localization via molecular biology methods. As a result,
there were 491 sequences defined as potato PPR members. In addition, we found the Restorer-of-fertility-likes clusters on chromosome 6, and we also analyzed the expression of four genes under abiotic stress and the subcellular localization of two proteins to attempt to explain the mechanism of PPR involved in abiotic stress. In general, our study gives an exhaustive analysis and hopefully provides help for
growth, development and metabolism in potato research.
Aplicação de extratos naturais na inibição do fungo Penicillium roqueforti
Authors: Sismer Ana Claudia , Hoinoski Juliane , Souza Maria Maria Clara Hasper de , Bortoli Kennidy de , Massarolo Kelly Cristina
Published: June 2024

O fungo Penicillium roqueforti é amplamente reconhecido por seu papel na produção do queijo Roquefort. Pertencente ao gênero Penicillium, este fungo é caracterizado por sua cor azul-esverdeada e é essencial na maturação de queijos de mofo azul, contribuindo para seu sabor e aroma únicos. No entanto, P. roqueforti também pode causar deterioração em outros produtos alimentícios, resultando em mudanças indesejáveis na qualidade dos mesmos. Diante disso, torna-se necessário desenvolver métodos eficazes para mitigar esse problema. Portanto, o objetivo do trabalho foi avaliar a atividade antifúngica in vitro dos extratos etanólicos de erva-mate (Ilex paraguariensis) e alecrim (Rosmarinus officinalis L.) frente ao fungo P. roqueforti. Para isso, três concentrações dos extratos 0,3%, 2,5% e 5% foram adicionados ao ágar batata dextrose (BDA) e distribuídos em placas de Petri. Após solidificação, o fungo foi inoculado com um disco de micélio ativo. As placas foram incubadas a 25°C para simular o desenvolvimento do P. roqueforti. Controles com meio BDA contendo solução de etanol também foram realizados. Os resultados mostraram que o extrato de alecrim na concentração de 5% reduziu o desenvolvimento micelial do fungo em 33,4%, enquanto as concentrações de 0,3% e 2,5% não apresentaram efeito inibitório. Por outro lado, o extrato de erva-mate não demonstrou atividade antifúngica em nenhuma das concentrações testadas. Apesar do extrato de erva-mate apresentar um maior teor de compostos fenólicos (474,59 ± 4,62 µg/mL) em comparação com o extrato de alecrim (167,31 ± 3,19 µg/mL), a inibição do fungo não foi observada. Isso sugere que a ação inibitória do extrato de alecrim não está exclusivamente relacionada aos compostos fenólicos, mas provavelmente à combinação de outros compostos bioativos presentes no extrato.

Published: June 2024

Os planos odontológicos passam a ser uma possibilidade de aumento da captação de pacientes e da renda mensal. As entidades de classe odontológicas criaram um mecanismo importante para auxiliar o cirurgião-dentista a estipular seus honorários, chamado Classificação Brasileira Hierarquizada de Procedimentos Odontológicos (CBHPO). Objetivou-se analisar honorários profissionais pagos por operadoras de planos odontológicos e comparar com a tabela CBHPO. Trata-se de pesquisa documental, descritiva, com operadoras de planos privados, cooperativa e associação. Foram coletadas tabelas de preços de honorários profissionais odontológicos de seis instituições e analisados os procedimentos referentes a consultas clínicas, dentística, cirurgia, prótese, endodontia, odontopediatria, prevenção e implantodontia. Algumas discrepâncias observadas foram no procedimento de aplicação tópica de flúor (R$ 7,26 e R$ 109,00 e com diferença de 93,33%), e na raspagem supra gengival (R$ 21,70 e R$ 234,00 com diferença de 92,62%). Nenhum convênio cobre o tratamento de implantes dentários. Os valores observados para pagamento de núcleo metálico fundido (R$ 39,00) não cobrem os custos da fase laboratorial, a restauração de uma face com resina fotopolimerizável, R$ 23,00, na CBHPO é de (R$ 166,00-86,14%). Conclui-se que os valores pagos pelas operadoras são inferiores aos recomendados pela tabela da CBHPO. Vários procedimentos de prótese dentária e implantodontia não são cobertos pelas operadoras.

Published: June 2024

Ninety-six isolates were collected at various depths and sea shores of the Bay of Bengal near Visakhapatnam Coastal of Andhra Pradesh. These isolates were screened for the isolation of lipase activity by tributyrin agar clearing method and cultured under submerged fermentation and assayed for extra cellular lipase production by using tributyrin as substrate. Cultural characteristics of the selected strain was done by incorporating different media. Various parameters namely morphological, biochemical, physiological and molecular were used for the characterization and identification of actinomycetes isolates. Results indicated that all the isolates showed lipolytic activity after primary screening. The marine isolate T9 was the most active one thus the same was selected for production of lipase. The 16S rDNA amplification for phylogenetic study revealed that the isolate was highly related to Nocardiopsis dassonvillei. In conclusion, these results increased the scope of finding industrially important marine actinomycetes from Visakhapatnam Coastal of Andhra Pradesh.
UMA MODELAGEM MAIS REALISTA DO TEMPO DE DESCOBERTA DE VIZINHOS PARA MECANISMOS DE DUTY CYCLE ASSÍNCRONO BASEADOS EM ESCALONAMENTO
Authors: Trabbold Beatriz , Carrano Ricardo Campanha , Passos Diego , Sousa Cledson de
Published: June 2024

A operação em ciclo de trabalho é um mecanismo fundamental para redes sem fio com dispositivos operados com bateria, como algumas redes de sensores sem fio. Devido à sua importância, este tipo de mecanismo é empregado em diversos protocolos de acesso ao meio. Nos ciclos de trabalho assíncronos baseados em escalonamento, os nós ativam e desativam suas interfaces de rádio de acordo com um escalonamento de slots preconcebido que garante alguma sobreposição de tempo de atividade entre dois nós, independente da diferença entre seus relógios internos, o que torna a comunicação possível. Este artigo apresenta um novo modelo para o Tempo de Descoberta de Vizinho (ou NDT, do inglês Neighbor Discovery Time). Diferente dos modelos anteriores, este trabalho modela o cenário onde as bordas dos slots dos escalonamentos de nós vizinhos podem não estar perfeitamente alinhadas – o caso mais comum na prática.

A hipertensão intracraniana é uma condição caracterizada pelo aumento anormal da pressão dentro dos crânios, podendo resultar em diversas causas como traumatismo craniano grave, hemorragias intracranianas, tumores cerebrais, edema cerebral ou acúmulo de líquido cefalorraquidiano. Esse aumento da pressão intracraniana pode levar a complicações graves como comprometimento do fluxo sanguíneo cerebral, lesão neuronal, hérnia cerebral e risco de morte. Portanto, o controle eficaz da pressão intracraniana é essencial para prevenir danos irreversíveis e melhorar os resultados clínicos em pacientes com essa condição. A fisiopatologia da hipertensão intracraniana envolve um complexo desequilíbrio no ambiente intracraniano, resultando no aumento anormal da pressão. Esse desequilíbrio pode ser desencadeado por diversas condições que levam a um aumento da pressão, como traumatismo craniano, hemorragias, tumores ou edema cerebral. O aumento da pressão intracraniana pode comprometer o fluxo sanguíneo cerebral, causar lesão neuronal e hérnia cerebral, representando uma ameaça grave à vida do paciente. As manifestações clínicas de hipertensão intracraniana incluem cefaleia intensa, alterações do nível de consciência, vômitos, déficits neurológicos focais e sinais de papiledema. Este estudo consiste em uma revisão sistemática da literatura publicada nos últimos 10 anos sobre a eficácia da craniotomia no manejo da hipertensão intracraniana. Os dados foram encontrados nas bases PubMed e LILACS, utilizando os descritores "craniotomia descompressiva" e "hipertensão intracraniana". Foram selecionados 10 estudos de ensaios clínicos que atenderam aos critérios de inclusão, como pacientes com hipertensão intracraniana submetidos a craniotomia. O reconhecimento precoce desses sinais e sintomas é essencial para um diagnóstico rápido e um manejo adequado da condição. O diagnóstico da hipertensão intracraniana envolve uma avaliação multidisciplinar, com a realização de exames de imagem, como tomografia computadorizada e ressonância magnética, além da medição direta da pressão intracraniana por métodos invasivos. O diagnóstico precoce é fundamental para iniciar o tratamento e prevenir complicações graves. Portanto, a associação entre craniotomia e diminuição da hipertensão intracraniana é valida e amplamente utilizada.

Transformer oil insulation breakdown voltage testing is usually carried out at high AC voltage using the SPLN 49-1 1982 standard. The electrodes used are hemispherical electrodes with a distance between the electrodes of 2.5mm. The breakdown voltage value of transformer oil insulation that meets the standards according to SPLN 49-1 of 1982 is 30 kV/2.5mm. In this research, a new Shell Diala B brand transformer oil insulation breakdown voltage test was carried out using the SPLN 49-1 1982 testing standard. The novelty of this research is using various electrode shapes and different electrode materials to test the breakdown voltage of the transformer oil's liquid insulation. The method used in this research is an experimental method where the test is adapted to the SPLN 49-1 standard of 1982. The electrodes used are ball, needle, and plate electrodes. Based on test results at a distance between electrodes of 2.5 mm, it was found that the breakdown voltage characteristics of stainless steel, brass, copper, and aluminum electrode materials varied and did not meet the SPLN 49-1 1982 standard, namely 30 kV/2.5 mm.

Microstructural Observations on the Durability of Stabilized Rammed Earth
Authors: Yahya Soura S. , Al-Sharrad Muayad A.
Published: June 2024

This study provides a qualitative microstructural investigation of fly ash geopolymers' role in rammed earth's durability against water ingress and contact erosion. A series of SEM (scanning electron microscopy) images were captured on geopolymer-stabilized as well as unstabilized rammed earth samples. These samples were fabricated from predefined amounts of sand and fine materials together with fly ash geopolymers in the laboratory by static compaction to 25 MPa inside rigid molds. Two standardized durability tests were performed, namely, the dip test and the spray (also known as erosion) test. The results of these tests reflected excellent durability properties (practically zero erosion) of the stabilized material. The microscopic investigation provided an insight into the reason behind this improvement, where geopolymer networks inhabited the macro and micro pores and served as a cementing agent interconnecting the earthen materials’ grains. On the contrary, grains of the unstabilized material were weakly bonded by the clay component of the mixture, as observed with the SEM images; therefore, they were more susceptible to erosion by water

Honey, I Shrunk the Columns: Recent Advances in the Design and Use of Narrow Internal Diameter UHPLC Columns
Authors: Muraco Cory E.
Published: June 2024

The quest for increased sensitivity for low-concentration samples continues at an accelerated pace, especially in the pharmaceutical and clinical environments. High-end mass spectrometry instruments can enable the analyst to detect analytes at attomolar concentrations, but can be prohibitively expensive and require well-trained scientists to operate and interpret the data. Another approach to improve the sensitivity of high performance liquid chromatography (HPLC) assays is by decreasing the internal diameter (i.d.) of the column. Reducing the column’s internal diameter down from 4.6 mm to 2.1 mm has been in practice for several decades. However, extra caution is required when considering going down below 2.1-mm i.d. into the “capillary-flow” format. This paper describes advances in column design that enable the analyst to achieve high sensitivity and efficiency when reducing the internal diameter of the column. After an introduction outlining the theory of increased sensitivity with narrow and capillary-scale internal diameter columns, a novel 1.5-mm i.d. column format will be presented detailing how sensitivities comparable to capillary-like separations can be achieved with this column geometry. Application examples will demonstrate the performance benefits of utilizing a 1.5-mm i.d. column geometry.
Unraveling Genetic Variability, Correlation and Path Analysis for Yield and Its Components in Barley (Hordeum vulgare L.)
Authors: Saha Sajal , Kumar Rahul , Bhadana Deepa , Kumar Pravesh
Published: June 2024

The current study aimed to assess the genetic variability of yield and yield-related traits while examining the direct and indirect effects of trait interactions. Conducted at a research farm in Chaudhary Charan Singh University, Meerut, Uttar Pradesh, India, the experiment involved fourteen parents and their BC1F1 crosses, analyzed using a randomized block design (RBD). Significant differences were observed among the varieties for most traits, indicating a broad range of mean values and diversity. Both phenotypic and genotypic coefficients of variance (PCV and GCV) were generally low, with biological yield showing the highest values (26.57 for GCV and 40.48 for PCV). PCV values were slightly higher than GCV values. Traits such as seed per spike, biological yield, flag leaf breadth, days of heading, and days of maturity exhibited relatively high heritability. Notably, grain yield showed high heritability and genetic progress, making it a favourable selection indicator. Several traits, including days of anthesis, days of maturity, and spike length, demonstrated significant positive correlations with yield while also showing significant negative correlations with grain filling period and biological yield. Conversely, these traits showed highly non-significant positive correlations with harvest index, plant height, thousand seeds weight, and chlorophyll content and highly non-significant negative correlations with tiller number and seeds per spike.

The impact of high-performance human resource practices on subjective career success: The mediating role of psychological capital and organizational commitment
Authors: Toyata Berk , Kızrak Meral , Çakar Mehmet
Published: June 2024

Utilizing insights from positive psychology, social exchange theory, and social cognitive career theory, this study aims to investigate the mediating role of psychological capital and organizational commitment in the relationship between high-performance human resource (HR) practices and subjective career success. Data were collected from a sample of 429 private sector employees working on European Union projects in Turkey. Hypotheses were tested using regression, correlation, and mediation analyses, as well as Sobel test statistics. Results indicate that high-performance HR practices, organizational commitment, and psychological capital positively influence subjective career success. Additionally, there is evidence that, unlike organizational commitment, psychological capital mediates the relationship between high-performance HR practices and subjective career success. Our study underscores the need for organizations to foster and develop psychological capital among their employees to maximize the effectiveness of HR practices in promoting subjective career success.

The purpose of the article is to examine the extent to which workplace well-being influences individual behaviours at work. Various studies have found that increasing the state of feeling good and seeing life positively influences the way a person responds or behaves. This article explores the causal relationship between the psychological and subjective well-being of individuals and their behaviour at work and/or at school. Additionally, it investigates the extent to which socio-economic status participates in the causal relationship between workplace well-being and behaviour at work and/or at school. To understand the predictive power of independent variables on behaviour in the workplace, we used linear regression models. Mediation tests were also used to quantify the extent to which socio-economic status influenced the confirmed causal relationship. The study reports the results of a sample of 533 Romanian respondents. Data were collected from university business students, based on a questionnaire administered online. The results confirm the prediction role of the psychological and subjective well-being of individuals in their workplace behaviour. Additionally, research confirms the mediation role of socio-economic status in this relationship.

This study presents a model inspired by the Burke-Litwin causal model of the organization, suitable to encompass both individual and organizational performance and aligned with the proposal of a structure explicitly adapted for sports organizations from De Knop. The model was tested on senior management in 131 tennis clubs registered in Serbia. Although some scholars are against the implementation of common management in sports organizations, the results show that well-structured total quality and human resource management processes genuinely increase the effectiveness of sports organizations. Our findings show that critical success factors of this approach were complexity-based leadership, clearly defined mission and vision of the organizations, informal communication paired with unambiguous policies and comprehensible procedures, and broader operational responsibilities given to the employees. The levels of legal compliance and reward management systems were the main weaknesses of these sports organizations.

Published: June 2024

Salmonella enterica is a bacterium that can cause serious infections in humans and animals, especially cattle. The identification and differentiation of S. enterica serotypes in cattle is important for epidemiological surveillance, disease prevention and control, and public health protection. However, the current methods and techniques for S. enterica detection have various challenges and limitations, such as low sensitivity and specificity, high cost and complexity, and the need for viable and pure bacterial cultures. Therefore, there is a need for further research and development of novel and improved methods and techniques that can overcome these challenges and provide reliable and accurate information on S. enterica serotypes in cattle. Such information can help to improve the understanding of the epidemiology, pathogenesis, and transmission of S. enterica in cattle, as well as to design and implement effective strategies for its prevention and control. This chapter reviews the current methods and techniques for S. enterica detection, such as culture-based methods, biochemical methods, molecular methods, phage-based methods, and biosensor methods, and discusses their advantages and disadvantages, as well as their future trends and perspectives.
Macrophages in the Inner Ear: Discoveries and Innovative Techniques Illustrating Their Key Roles in Homeostasis and Inflammation
Authors: Mohamed Bedeir Mai , Ninoyu Yuzuru
Published: June 2024

Inner ear macrophages, also known as cochlear macrophages, are immune cells that play a crucial role in maintaining the homeostasis and hearing function of the inner ear. They are responsible for responses to cochlear insults, such as noise exposure, ototoxic drugs, and surgical injuries. These cells have been shown to be present in the spiral ganglion, spiral ligament, and stria vascularis of the inner ear. As our understanding of inner ear macrophages continues to evolve, it is becoming evident that these cells are not just inert populations in the auditory system but are active participants in the complicated mechanics of inner ear homeostasis. Nevertheless, a comprehensive understanding of the roles and functions of macrophages within the auditory system is lacking. This review explores the presence, origin, and multifaceted roles of inner ear macrophages, elucidating their significance in maintaining auditory function, while also highlighting their potential inimical role in inner ear inflammation. The information collated herein has important implications for the development of therapeutic strategies aimed at preserving or restoring auditory function.
Quantum Key Distribution Approaches
Authors: Abushgra Abdulbast
Published: June 2024

Irrespective of the duration for which the classical system based on bits remains secure, the imminent advent of quantum systems demands a robust cryptographic mechanism to safeguard both manifest data and the existing system’s structure and infrastructure against various threats. Quantum mechanics may provide a solution in the form of quantum key distribution (QKD), a set of processes designed to generate and exchange cryptographic keys between two parties. Each unique method and algorithm within QKD can be characterized as a protocol. In 1984, Charles Bennett and Gilles Brassard introduced the first QKD protocol, BB84. Subsequent QKD protocols have been developed based on different principles, including Heisenberg’s uncertainty principle, polarization, entanglement, and the non-cloning theory. Other scientists have enhanced some QKD protocols, leading to variations with different names. However, not all these protocols can be implemented in classical systems, as they specifically require a quantum system. The current challenge revolves around the complex and pressing need to develop a QKD protocol that can function effectively on classical systems, quantum systems, or both. In the chapter, QKD protocols are comprehensively examined, with each protocol being meticulously reviewed through technical steps elucidating how the protocol facilitates the exchange of secret keys. Each QKD protocol is dissected to unveil its underlying mechanisms, providing a detailed exploration of the cryptographic procedures involved in generating and exchanging secure cryptographic keys.
Digital Entrepreneurship in the Fourth Industrial Revolution and Beyond

Published: June 2024

The nature of the confusion that underpins entrepreneurial processes and outcomes and the strategies for addressing it have been changed due to the Fourth Industrial Revolution brought about by the development of digital technologies. Technology is the main force behind digital entrepreneurship. The Fourth Industrial Revolution’s technological development is both a limitation and a turning point for digital entrepreneurship. Most importantly, it has been assumed that the Fourth Industrial Revolution will provide additional drivers for the future of digital entrepreneurship. The purpose of this chapter was to compile the most recent research on digital entrepreneurship, investigate how the Fourth Industrial Revolution’s digital transformation has affected this field, and explore how the COVID-19 pandemic has affected it. The study conducted an evidence-based literature review on digital entrepreneurship, using a qualitative analysis method and content analysis. The research found that digital businesses were unaffected by Covid-19 due to their familiarity with digital methods and business models. Covid-19 benefited digital entrepreneurs by allowing them to pivot to new markets and segments quickly. However, it also threatened their survival due to disruptions in their business model and supply chain. The study suggests that digital entrepreneurship in the Fourth Industrial Revolution is promising to continue.
ANÁLISIS COMPARATIVO DEL PROCESO DE DESARME, DESMOVILIZACIÓN Y REINTEGRACIÓN: CASO FILIPINAS (MNLF/MILF) Y COLOMBIA (FARC-EP)

El proceso de posconflicto es una de las etapas más exigentes en la vida política de los Estados, pues exige un sólido sistema de medidas garantizadas para adelantar exitosamente este proceso. Tanto Colombia como Filipinas, han tratado de concluir décadas de largos conflictos internos armados mediante procesos de negociación con los actores armados ilegales, cuyas motivaciones han oscilado entre las diferencias religiosas y lucha por la autonomía en el caso de Filipinas, y acceso al poder para el pueblo en el caso de Colombia. Ambos países en el marco del proceso de paz, propusieron implementar mecanismos técnicos políticos y sociales de desarme, desmovilización y reintegración (DDR). El objetivo del siguiente artículo es comparar dichos procesos de DDR que se han adelantado con los grupos armados internos en ambos países. Como hallazgo, se encontró que el carácter cambiante de la naturaleza de los conflictos y el creciente movimiento de las disidencias tanto en Filipinas como en Colombia, han puesto en algunos casos los procesos de DDR en cuestión.
LA FANTASMAGORÍA DE LA CIUDAD MODERNA EN WALTER BENJAMIN
Authors: Mancilla Mauricio
Published: June 2024

El presente ensayo aborda la fantasmagoría de la ciudad moderna a partir de la obra de Walter Benjamin (1892-1840). Se examinará el complejo entramado que configura la ciudad en la modernidad y cómo esta moldea la vida cotidiana. Para tal efecto, se analizarán algunos de los textos más importantes de Benjamin, especialmente, el monumental proyecto inacabado sobre las galerías de París, una especie de precursor del moderno centro comercial. En estos textos la fantasmagoría de la ciudad moderna emerge como el centro de gravedad en la reflexión de Benjamin, quien reconoce las consecuencias producto de una rápida industrialización y urbanización, así como la emergencia de una cultura de masas. Por otra parte, este artículo explora la transformación de la ciudad moderna en una mercancía que oculta su trama capitalista. A través de una incipiente teoría crítica de lo urbano, Benjamin ofrece una radiografía íntima de la modernidad, desde donde emergen nuevas formas de experimentar la relación entre la memoria, el entorno urbano y los procesos históricos.
