The article examines how distrust regarding the COVID-19 pandemic has served as a catalyst for the diffusion of conspiracy theories. It discusses the nature of conspiracy theories, their relationship with institutional distrust, and their representation in the social media. The methodology used is based on the analysis of hashtags from over one million tweets to determine if certain theories act as "gateways" to others. The findings suggest that logical ties exist between distinct conspiracy theories, influenced by distrust towards specific institutions and amplified by the COVID-19 crisis. It is concluded that the combination of conspiracy theories is not random, but rather, it follows an internal logic that is based on distrust, since these theories are interconnected in an internally coherent way within the context of the pandemic.

The U.S. National Parks encompass a variety of biophysical and historical resources important for national cultural heritage. Yet how these resources are socially constructed often depends on the beholder. Parks tend to be conceptualized according to their (fixed) geographic context, so our understanding of this system of systems is dominated by this geographic lens. To expose the systemic structure that exists beyond their geographic embedding, we analyze three representations of the National Park System using park–park similarity networks according to their cooccurrence in (1) about 423,000 news media articles; (2) about 11,000 research publications; and (3) about 60,000 species inhabiting parks. We quantify structural variation between network representations by leveraging similarity measures at different scales: park level (park–park correlations) and system level (network communities' consistency). Because parks are governed and experienced at multiple scales, cross-network comparison informs how management should account for the varying objectives and constraints that dominate at each scale. Our results identify an interesting paradox: Whereas park-level correlations depend strongly on the representative lens, the network communities are remarkably robust and consistent with the underlying geographic embedding. Our data-driven methodology is generalizable to other geographically embedded socioenvironmental systems and supports the holistic analysis of systems-level structure that might elude other approaches.

This paper analyses the use of social media by Uruguayan teachers, as well as the role of educational models on the Twitter/X platform. This is a mixed (quantitative-qualitative) study based on a survey of 206 teachers, a social media analysis of the Twitter/X platform, and in-depth interviews with nine leading educators identified on it. The results show that teachers use social media, in general, to find resources, learn from others and stay up to date with current developments in education. Leading educators, on the other hand, are particularly active on Twitter/X, where they share their opinions, thoughts and resources. They have training and professional experience in education and value the interaction, teaching and influence they generate on social networks. The paper also identifies some tips and warnings for using social media in an ethical, respectful and constructive manner. [ABSTRACT FROM AUTHOR]

Despite considerable improvements in social impact assessment practice, the shortfalls and neglected status of social impact assessment persist. Integrated impact assessments have been suggested to address some of these shortcomings. Due to its transdisciplinary nature, disaster risk assessment has been identified as an emerging area that could assist social impact assessment in managing social changes and risks and improving community resilience. Emerging research from South Africa and abroad have shown that social impact assessment–disaster risk assessment integration offers opportunities for streamlining and improved practice across four areas, that is, theoretical discourses, legislative and statutory provisions, practitioner perspectives and combined methodologies. The resulting streamlined social impact assessment and disaster risk assessment will be more suitable for 21st-century challenges, allowing for enriched social impact assessment practice, contributions to social sustainability and strengthening of the social resilience of at-risk communities. From observations of the South African context, we suggest that streamlined social impact assessment and disaster risk assessment will optimally address the challenges of developing sustainably and enhancing the resilience of at-risk societies in the 21st century in South Africa, the global south and also the rest of the world.

The mainstream approach of social vulnerability to flood risk faces some challenges regarding its ability to address the complexity of its causal processes. The objective of this study was to analyse the causal processes of social vulnerability to flood impacts from a relational perspective. To this end, a social network analysis was performed that identified the conditions and causes of social vulnerability and systematically articulated the relationships between them. This analysis was tested on the specific case of flood risk on the coast of the province of Alicante (SE Spain). To ascertain the conditions and causes of social vulnerability to flood risk, a multidisciplinary group of local experts was consulted, and the resulting data processed in a relational way using Atlas.ti and Gephi softwares. The result was a social vulnerability network comprising 84 nodes and 189 edges distributed into four dimensions: the adaptive capacity of tourists, socio-economic structure, land use planning and risk management. The information was ranked for betweenness centrality, revealing the components with highest causal power of social vulnerability to social impacts in flooding events: low flood risk awareness, economic growth based on real estate boom, property speculation and lack of political interest in flood risk management. This proposal places emphasis on the driving forces of social vulnerability and not exclusively on the specific adaptive conditions of the population, which allows a strategic identification and management of generative forces that ultimately induce the social impacts of floods.

The potential for species to shift their ranges to avoid extinction is contingent on the future availability and accessibility of habitats with analogous climates. To develop conservation strategies, many previous researchers used a single method that considered individual factors; a few combined 2 factors. Primarily, these studies focused on identifying climate refugia or climatically connected and spatially fixed areas, ignoring the range shifting process of animals. We quantified future habitat availability (based on species occurrence, climate data, land cover, and elevation) and accessibility (based on climate velocity) under climate change (4 scenarios) of migratory birds across the Yangtze River basin (YRB). Then, we assessed species' range‐shift potential and identified conservation priority areas for migratory birds in the 2050s with a network analysis. Our results suggested that medium (i.e., 5–10 km/year) and high (i.e., ≥ 10 km/year) climate velocity would threaten 18.65% and 8.37% of stable habitat, respectively. Even with low (i.e., 0–5 km/year) climate velocity, 50.15% of climate‐velocity‐identified destinations were less available than their source habitats. Based on our integration of habitat availability and accessibility, we identified a few areas of critical importance for conservation, mainly in Sichuan and the middle to lower reaches of the YRB. Overall, we identified the differences between habitat availability and accessibility in capturing biological responses to climate change. More importantly, we accounted for the dynamic process of species' range shifts, which must be considered to identify conservation priority areas. Our method informs forecasting of climate‐driven distribution shifts and conservation priorities. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate the association between the media and the public network agendas concerning Syrian refugees in Türkiye, as an exemplar of a polarized media system within the context of a competitive authoritarian regime to gain insight into the cognitive effects of media in such a context internationally. Large-scale media and nationally representative mind-mapping survey data analysis show that the media's network agenda is only significantly transferred to the pro-government individuals, while no significant effect was found on pro-opposition individuals from any media outlet regardless of their political stances. Implications are discussed. [ABSTRACT FROM AUTHOR]

Este estudio examina la evolución de la red global de grandes empresas y accionistas antes y después de eventos significativos como la pandemia y la guerra en Ucrania. En primer lugar, se seleccionan 15.000 corporaciones del mundo en los años 2019 y 2023, y se identifican sus respectivos accionistas para analizar los cambios en la cohesión de la red de 2-modos. En segundo lugar, se crea y analiza la red de países derivada de la red de empresas. En tercer lugar, se seleccionan las 1.000 mayores empresas y se analiza la cohesión de las redes de 1-modo de empresas por empresas, y accionistas por accionistas. Los resultados indican un aumento de la cohesión entre las grandes empresas debido al aumento en el número de accionistas y a que estos accionistas invierten en grandes empresas simultáneamente. Además, la red global de empresas y accionistas se vuelve más segmentada en comunidades, sugiriendo un escenario geoeconómico más multipolar.

Este artículo analiza la relación existente entre medidas de pobreza y la robustez de la red eléctrica colombiana, en el contexto de la seguridad. Para hacerlo, se construyó un tablero de indicadores que permitió triangular la metodología de los índices multidimensionales de pobreza con los modelos de redes. Como conclusión, se encontró una gran fragilidad de la red eléctrica, representada por el bajo número de nodos asociados a los departamentos de Colombia. La robustez de la red nacional es de 0,0816, un valor bajo comparado con los valores típicos de redes no optimizadas. Se encontró también una relación inversa entre la tasa de homicidios y las medidas de pobreza, incluida la pobreza energética. Asimismo, se halló una correlación alta (0,94) entre la pobreza multidimensional y la pobreza energética en Colombia.

El objetivo principal de este estudio fue examinar la dinámica de los síntomas depresivos en población peruana según identidad étnica, y encontrar el síntoma central mediante análisis de redes. Para ello, se analizó la base de datos de la Encuesta Demográfica y de Salud Familiar (ENDES), 2020. La muestra fue aleatoria y estuvo conformada por 32 634 participantes, a quienes se les administró el Patient Health Questionnaire 9. Se realizó un análisis de redes para conocer los síntomas centrales de la depresión de acuerdo con su identidad étnica. Los hallazgos señalaron que, en todos los grupos étnicos, el síntoma central fue el ánimo deprimido, a excepción de la población aymara, en quienes la centralidad recae en los problemas del sueño. Además, la menor interacción entre síntomas se presentó en quienes se identificaron como nativos amazónicos. Se concluye que la depresión puede manifestarse de manera distinta entre los grupos étnicos, especialmente en la población aymara, donde se encontró una expresión más somática, expresada en los problemas del sueño.

Background: Comorbidity between posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD) is surrounded by diagnostic controversy and although various effective treatments exist, dropout and nonresponse are high.Objective: By estimating the network structure of comorbid PTSD and BPD symptoms, the current study illustrates how the network perspective offers tools to tackle these challenges.Method: The sample comprised of 154 patients with a PTSD diagnosis and BPD symptoms, assessed by clinician-administered interviews. A regularised partial correlation network was estimated using the GLASSO algorithm in R. Central symptoms and bridge symptoms were identified. The reliability and accuracy of network parameters were determined through bootstrapping analyses.Results: PTSD and BPD symptoms largely clustered into separate communities. Intrusive memories, physiological cue reactivity and loss of interest were the most central symptoms, whereas amnesia and suicidal behaviour were least central.Conclusions: Present findings suggest that PTSD and BPD are two distinct, albeit weakly connected disorders. Treatment of the most central symptoms could lead to an overall deactivation of the network, while isolated symptoms would need more specific attention during therapy. Further experimental, longitudinal research is needed to confirm these hypotheses.Trial registration: ClinicalTrials.gov identifier: NCT03833453.

The aim of this piece of research is to study productivity and scientific collaboration in the main Spanish sociology journals from a gender perspective. The authorship of 3171 documents published in these journals during the period 2001-2020 was analysed using bibliometric and social network analysis techniques. While there was an overwhelming male dominance at the start of the period, the results show a steady trend towards parity; however, this was only achieved during the 2016-2020 period, and not in all indicators. In conclusion, gender advances in sociology research have only partially come to fruition in Spain, but the scholarly monitoring system cannot be held accountable for this. [ABSTRACT FROM AUTHOR]

El presente artículo analiza el uso de las redes sociales por parte de los docentes uruguayos, así como el papel de los referentes educativos en la plataforma Twitter. Se trata de un estudio mixto (cuantitativo y cualitativo) basado en una encuesta a 206 docentes, un análisis de redes sociales (ARS) en la red Twitter y entrevistas en profundidad a nueve referentes educativos identificados en la mencionada red. Los resultados muestran que los docentes utilizan las redes, en general, para encontrar recursos, aprender de otros y conocer temas de actualidad, mientras que los referentes educativos se destacan por su actividad en Twitter, donde comparten sus opiniones, reflexiones y recursos. Los referentes educativos se caracterizan por ser profesionales con trayectoria y formación en el campo de la docencia, que valoran la interacción, el aprendizaje y la influencia que generan en las redes sociales. También se identifican algunos consejos y desafíos para intervenir en ellas de manera ética, respetuosa y constructiva.

Esta investigación se enmarca en el campo de la Cultura Organizacional y el coaching educativo. La cultura organizativa se instaura cada vez más en los distintos ámbitos. Vinculada a la escuela, favorece la mejora del desarrollo personal y académico de los estudiantes y docentes. El objetivo es analizar las tendencias sobre las prácticas para la mejora del rendimiento, la eficacia y el bienestar de los educadores, y cómo está mejorando el aprendizaje y el desarrollo de los estudiantes. La revisión bibliométrica de los datos se realizó a partir de las palabras clave: Organizational Culture OR Educational Coaching AND Education, limitando los registros a aquellas publicaciones categorizadas en el campo de las Ciencias Sociales. La búsqueda se realizó en inglés y se analizaron las siguientes dimensiones: tema, tipos de publicación, área temática, país, publicación, autor y año, ambas tratadas mediante estadística descriptiva. Los resultados reflejan un total de 893 documentos indexados en Ciencias Sociales. Por último, se analizó la concurrencia temática de las palabras clave mediante el software VosViewer, que agrupamos en 6 categorías principales (organización, cultura organizacional, educación, liderazgo, relaciones interprofesionales y comunicación interpersonal). Según las investigaciones actuales, la relación entre cultura organizativa y coaching educativo mejora la eficacia, bienestar y liderazgo en instituciones educativas. Entre las principales conclusiones cabe destacar la necesidad de explorar nuevas vías de colaboración a escala internacional.

Since the 1991 Constitution of Colombia, many elements of the electoral dynamics have been changing in this country. One of them, perhaps the most important one, is the significance that electoral alliances have taken for local and regional elections. With an analysis of the 2015 and 2019 elections, this article describes how inter-party alliances are formed in these two cases. For this purpose, a network analysis is used to establish which alliances have taken place, the number of them, the stakeholders involved, among other elements. [ABSTRACT FROM AUTHOR]

Background and objective: The current study aimed to investigate the within-day symptom dynamics in PTSD patients, specifically focusing on symptoms that most predict changes in other symptoms. The study included a baseline diagnostic assessment, followed by an assessment using the experience sampling method (ESM) via a smartphone. Method: Participants answered questions related to their PTSD symptoms four times per day for 15 consecutive days (compliance rate 75%). The clinical sample consisted of 48 treatmentseeking individuals: 44 with PTSD as a primary diagnosis, and four patients with subsyndromal PTSD, all of whom had not yet begun trauma-focused treatment. The ESM assessment included the 20 items from the PTSD Checklist for DSM-5, five items from the International Trauma Questionnaire (ITQ) assessing disturbances in relationships and functional impairment, and two items from the Clinician-Administered PTSD Scale for DSM-5 assessing symptoms of depersonalization and derealization. Results: Temporal networks (prospective associations between symptoms) showed that changes in hypervigilance predicted changes in the greatest number of symptoms at the next time point. Furthermore, hypervigilance showed temporal connections with at least one additional symptom from each of the DSM-5 PTSD symptom clusters. Conclusions: Results show that the contemporaneous network (representing the relationship between given symptoms within the same assessment occasion) and the temporal network (representing prospective associations between symptoms) differ and that it is important to estimate both. Some findings from earlier research are replicated, but heterogeneity across studies remains. Future studies should include potential moderators. [ABSTRACT FROM AUTHOR]

El estigma público del suicidio es una barrera potencial para su prevención, un obstáculo para la búsqueda de apoyo profesional y perjudica el bienestar psicológico y físico de las personas afectadas. El objetivo de este estudio fue analizar la asociación y centralidad del estigma público del suicidio en adultos peruanos de población general. Participaron 1013 adultos (55.6 % mujeres) que respondieron un cuestionario de estigma del suicidio. Se estimó un modelo de red gaussiano para examinar sus propiedades globales, locales y comparación de estructuras según sexo. Los resultados demostraron asociaciones más fuertes entre nobles y dedicadas (r = .57), aisladas y solitarias (r = .47), inmorales y una vergüenza (r = .41). Los nodos centrales y de predictibilidad fueron inmorales, vengativos, vergüenza, perdidos e irresponsables. Además, tanto para las mujeres y hombres, el nodo central fue inmorales, aunque las mujeres describieron como vengativos y una vergüenza, mientras que los hombres como solitarios y cobardes. En conclusión, se evidenció actitudes estigmatizantes hacia las personas que mueren por suicidio, en donde las mujeres y hombres presentan una percepción diferente. Los programas de alfabetización sobre el suicidio pueden reducir el estigma público en la población general.

Introducción: El Sistema de Ciencia, Tecnología e Innovación de Colombia (SNCTI) clasifica los investigadores como Junior, Asociado y Senior según su productividad. Actualmente no resulta fácil ubicar fuentes que exploren el trabajo de investigadores en educación matemática dentro de este sistema. Objetivo: Analizar el perfil científico de investigadores en educación matemática a partir de su producción y redes de cooperación académica con el propósito de caracterizar el corpus científico de la disciplina y sus dinámicas productivas. Metodología: Estudio cuantitativo, retrospectivo y correlacional, se analizó la producción intelectual y las propiedades de las redes de coautoría de 281 investigadores durante el periodo 2016-2020. Resultados y discusión: Se identifica baja productividad, la mayoría no está clasificado como investigador y 44.1% no ha generado ningún producto en los últimos cinco años. El perfil profesional y de producción no muestra diferencias entre hombres y mujeres, en cambio, la estructura de las redes de coautoría se relaciona directamente con indicadores de producción y cooperación. Conclusiones: Generar nuevo conocimiento en matemática educativa es una tarea vigente para los estudiosos de la disciplina, con frecuencia muchos se autodenominan investigadores, pero sus prácticas productivas les contradicen. Estos profesionales están llamados a la profesionalización científica y a incluirse en redes académicas que coadyuven en esa meta.

A lo largo de la última década se han venido produciendo transformaciones radicales en el entorno interno y externo del sistema global de educación superior, lo cual incrementa los desafíos de los sistemas de gestión de estas instituciones para la adaptación. El presente artículo realiza un análisis bibliométrico de las investigaciones sobre gestión en educación superior publicadas entre 2011 y 2020 desde un enfoque mixto. A partir de un corpus de 936 artículos y revisiones indexadas en Scopus, se ha realizado, mediante la coocurrencia de palabras clave asignadas por las personas autoras a las publicaciones, un mapa científico. En una arista cuantitativa, este procedimiento permitió identificar la frecuencia de cada concepto, sus vínculos mutuos y su agrupación en clústeres. Posteriormente, un análisis de carácter eminentemente cualitativo hizo posible describir las temáticas centrales de cada clúster. Se encontró una estructura de once clústeres o líneas temáticas, la diversidad temática es coherente con el carácter altamente complejo del entorno interno y externo de los sistemas de gestión de educación superior y de los cambios recurrentes que estos han enfrentado en los años recientes. De este modo, el trabajo sistematiza los resultados y problemas relevantes para el campo, al tiempo que entrega luces respecto a los ámbitos en los que se deberían enfocar las futuras revisiones del estado del arte y orientaciones para guiar la problematización de las discusiones más pertinentes en este estadio de desarrollo del campo.

La colaboración entre investigadores e investigadoras es esencial para el desarrollo de su práctica profesional y del conocimiento. Esta investigación describe la colaboración intramuros de diferentes áreas de conocimiento. Para lograr este objetivo, se seleccionaron los cuatro grupos de investigación de mayor prestigio de las áreas de Ciencias de la Educación, Psicología, Computación y Ciencias Físicas de la Universidad Autónoma de Madrid. Mediante el análisis de la coautoría en los artículos de investigación publicados en los últimos cinco años por sus miembros, se estimaron la densidad, distancia geodésica, grado de centralidad, poder de Bonacich, grado de intermediación y grado de cercanía de cada grupo utilizando como técnica el Análisis de redes sociales. Los resultados demuestran la existencia de diferentes tipos de redes de colaboración y cultura colaborativa para cada uno de los grupos de investigación. Destacan los grupos de Computación y Ciencias Físicas como los más cohesionados, pero son los grupos de Ciencias de la Educación y Psicología los más abiertos, diversos y con un especial interés en el establecimiento de relaciones con el exterior. A la luz de los resultados obtenidos, se insta a explorar la coautoría en el resto de áreas del conocimiento y se declara la necesidad de apoyo de las administraciones y centros de investigación para potenciar la colaboración entre investigadores.

Se realizó una investigación de artículos científicos sobre innovación en las pequeñas y medianas empresas a nivel global, planteando como objetivo determinar las técnicas, enfoques cualitativos y cuantitativos aplicados en los estudios de estas empresas publicados en Scopus en el periodo de 1999 al 2019, además a través del análisis de redes sociales se identificaron las tendencias en el periodo 2020-2022. Para esto se realizó un análisis de contenido de 62 artículos en revistas Scopus entre 1999 y 2019, así como el análisis de redes de 1.091 artículos que abordan innovación en las pequeñas y medianas empresas. Los resultados muestran que la investigación en el primer periodo se realiza mayoritariamente a través de estudios cuantitativos siendo las técnicas más utilizadas los cuestionarios, seguidos de los modelos econométricos. En cuanto al análisis de redes se identifica que las tendencias del último periodo son la innovación del modelo de negocio, economía circular, innovación verde, Covid-19, manufactura, innovación tecnológica, transformación digital y Vietnam. Como conclusión se destaca que la investigación de innovación tecnológica es de carácter aplicada y que este tipo de empresas tuvieron relevancia en la pandemia viéndose obligadas a la reestructuración y cambio de modelos productivos incorporando la transformación digital.

Las sociedades Cooperativas de Energía están cambiando la realidad del sector energético. Esto es un tema incipiente de investigación que da lugar a una emergente e invisible estructura cientifica. Conocer a esta estructura puede originar unas oportunidades y un apoyo de referencia. A partir de este objetivo y mediante un análisis de red (UCINET-6), se construyeron tres redes: las personas autoras, los centros de afiliación y los países donde radican los trabajos académicos sobre las cooperativas de energía. Se analizaron 47 aportaciones, 24 fuentes, 113 personas autoras pertenecientes a 79 centros de investigación ubicados en 20 países. Los resultados indicaron que los personas autoras suelen cooperar en la producción científica, aunque la colaboración es local, pues ella se origina entre personas pertenecientes a mismos centros y países. Se halló una estructura de red fragmenta y centralizada donde 10 personas científicas son responsables de una producción específica.

Work stress has been identified as a critical factor affecting mental health in police officers. Psychosocial factors increase the impact of work stress on police officers and, in the long run, contribute to the onset of burnout symptoms. In this research a sample of 323 was studied to study the relationship between psychosocial risk factors and the probability of suffering burnout symptoms. The participant’s answers to the MBI-GS and F-PSICO (version 4.0) were analysed by using network analysis. The results show that psychosocial risk factors are strongly associated in network models when higher level of cynicism and emotional exhaustion are observed. Additionally, higher levels of burnout in police officers were observed when lower autonomy, higher psychological demands, role ambiguities and a lower perceived social support were present. Results are discussed considering its theoretical and applied relevance to design healthier work environments and efficient psychological interventions. [ABSTRACT FROM AUTHOR]

Social, political, and economic institutions covary with one another in heterogenous ways across space and time. Social Network Analysis (SNA) offers a set of analytical tools and conceptual frameworks that have allowed for formal comparisons of interactions, affiliations, and relationships in reconstructing historical trajectories of institutional change. Although archaeologists have made full use of a range of metrics that describe the structural variation of social networks, formal approaches to analyzing the covariance of networks, and the institutions that structured networks in the past, remain undertheorized. In most cases, descriptive metrics are compared between networks built from different datasets or networks separated in time. Using quadratic assignment procedure (QAP) correlations to compare matrices of archaeological data, I draw on a ceramic dataset of approximately 350,000 sherds from the Southern Appalachian region to investigate how decisions related to manufacture choice and to stylistic design covaried with one another between roughly AD 800 and 1650. I explore how material attributes may or may not vary independently of one another and what that means for our analyses of the institutions they reflect. The results contribute to broader comparative analyses of institutional change and perennial discussions of social evolution. [ABSTRACT FROM AUTHOR]

La ganadería, el transporte y el aprovechamiento de bovinos son problemas asociados con la dotación de recursos, la distancia recorrida y los tipos de mercado. Se investigó la estructura de la red de movilización de ganado bovino por mercado a nivel municipal y estatal en México durante el periodo 2017-2021. Los datos se analizaron con medidas de estructura económica y de Análisis de Redes Sociales. En el periodo de análisis, un promedio anual de 8.9 millones de cabezas de ganado fueron movilizadas en México: 57.9 % interestatal y 42.1 % intra estatal. Los mercados más importantes fueron para rastro y engorda, el resto correspondió a repasto, reproducción, ferias y espectáculos. La especialización promedio de los mercados y de los estados fue baja, con mayor especialización en el mercado para espectáculos. La estructura de la red estatal de todos los mercados presentó un alto grado promedio y de densidad, pero baja centralidad de salida y entrada. Estas medidas hacen que, en promedio, los estados puedan conectarse en 1.2 pasos a la red nacional y 1.7 en la red por motivo. Se concluye que la estructura estatal del mercado de bovinos en México se compone de 32 orígenes, 32 destinos, seis mercados y mayor movilización interestatal de sur al norte del país.

El presente trabajo pretende abordar, desde una perspectiva bibliométrica, las investigaciones sobre la precariedad laboral y el trabajo en Chile. Para ello construimos una base de datos con las publicaciones indexadas y sus autores para construir mapas de ciencia y redes de colaboración detrás de las publicaciones que cumplían el criterio de búsqueda. Se analizaron las agrupaciones temáticas detrás de los estudios de precariedad en Chile mediante la aplicación de redes de co-palabras estableciendo agrupaciones temáticas. Los resultados obtenidos nos permiten concluir ciertas temáticas comunes en los estudios del trabajo donde existen temáticas emergentes y temáticas consolidadas en grupos de investigación.

Objective: To analyze the structure of social, technical, and commercial relationships established between coconut producers of the Pacific coast of the Cauca Department in Colombia. Methodology: The Social Network Analysis methodology was used. This methodology studies the structure and dynamics of the relationships established among actors. A survey was applied to 676 producers, and the information was analyzed based on the indicators of density, centralization, in-degree centrality and Modularity Class. Results: The indicator of density is low in all analyzed networks, which means incipient levels of social capital and cohesion. The resulting networks are decentralized, which means that there are several actors that are an important source of consultation. The clusters are configured based on geographic conditions and around recognized actors given their trajectory and experience. Limitations: Lack of evidence to support the relationship between social capital and development, lack of information and high degree of abstraction. Conclusions: Low levels of social capital around the activity were found, which result in information associated with the coconut production chain not flowing easily between actors and communities. Geographic conditions fragment existing relationships between producers, forming different clusters that hardly communicate with each other. The relevant actors identified are producers with extensive experience in the activity, collectors, and cooperatives. [ABSTRACT FROM AUTHOR]

Several studies have indicated a type of hierarchical capitalism in Latin America, characterized by the presence of multinational and state corporations, diversified multi-enterprise groups, low-skilled labor, and segmented labor markets. From the perspective of ownership networks, we explore who the owners of large Brazilian corporations are. These networks reveal actors and groups with prominent positions in the structure and ownership of companies. Thus, this article proposes to 1) describe the ownership network of the largest Brazilian corporations; 2) analyze the density, average degree, modularity, and the number of components connected in this network; 3) analyze measures of weighted degree centrality, intermediation, and eigenvector; 4) identify and analyze subgroups in the network, and 5) relate the configuration of the ownership network with hierarchical capitalism in the Brazilian context. The results point to prominent positions of financial shareholders, the Brazilian state (state-owned firms), and groups composed mostly of large multinationals, financial firms, families, and state-owned firms, confirming that the ownership structure is strongly linked to these players.

Este trabajo caracteriza el modo en que se articulaba el territorio del n de la Carpetania romana a través de sus vías de comunicación principales y secundarias. En este caso hemos enfocado este trabajo desde una perspectiva alternativa alejada de las tradicionales aproximaciones urbanocéntricas. Para ello, hemos realizado una simulación de la red de comunicaciones en el n de la Carpetania a través de Sistemas de Información Geográfica. Los resultados para las vías principales se ajustan notablemente bien con las vías descritas en las fuentes textuales antiguas. Esto nos ofrece una gran fiabilidad para poder analizar la articulación del territorio a través de las vías secundarias y caminos rurales. Mediante herramientas derivadas de los análisis de redes hemos analizado la localización de algunos de los asentamientos más característicos en la red viaria, así como las áreas con mayor accesibilidad. Estos análisis apuntan a que las aldeas y aglomeraciones presentes en el territorio jugaban un papel crucial en la articulación territorial, principalmente en aquellas áreas menos cubiertas por las áreas de influencia municipales.

Insomnia is a sleep disorder associated frequently with physical and emotional health problems. Evidence suggests that it is a recurrent problem in adults in the general population, identifying fewer hours of sleep and poor sleep quality. Objective. To analyze the association of insomnia symptoms and identify core symptoms in Peruvian adults from the general population. Method. The sample consisted of 351 adults (53% men) who responded to the Athens Insomnia Scale. A regularized partial correlation network model was estimated. Results. Sleep duration, overall quality, and sleep malaise for problems were the most central symptoms in the network. The strongest conditional associations emerged between duration and sleep quality, malaise for problems sleep and interference with daily functioning. The network structure was accurate and stable (CS = .749). Conclusions. Sleep duration, overall quality, and sleep malaise for problems are relevant symptoms for understanding insomnia in adults of general population. Addressing those symptoms from cognitive behavioral therapy could improve anticipated awakenings, sleep initiation difficulties and sleepiness. [ABSTRACT FROM AUTHOR]

Covid-19 has generated several psychological impacts on people's lives and brought new challenges for dealing with the pandemic's repercussions. Objective: The objective was to analyse the relationship between the symptoms of fear of Covid-19, anxiety, and depression using different samples extracted at three distinct time-points. This study performed a network analysis of the fear of Covid-19 and anxiety- and depression -related symptoms based on data collected during the Covid-19 pandemic. Method: Three yearly cross-sectional surveys were conducted based on independent samples (2020-2022) of Brazilian adults (Time-point 1, Time-point 2, and Time-point 3 with 1,520, 1,523, and 1,517 participants, respectively). The Fear of Covid-19 Scale, the Generalised Anxiety Disorder Scale (7 items), and the Patient Health Questionnaire (9 items) were applied. The network structure invariance, the global strength invariance, and the strength of centrality index between the samples were compared. Results: Items from the three instruments had high values (>70%) in all samples (excluding the fear of Covid-19 at Time-point 3). Depression and anxiety symptoms increased, while fear-related behaviours decreased. Network analysis indicates that networks became progressively more parsimonious, and few edges connected different scales. Network comparisons revealed similar structures, but key differences were found: Time-point 1 showed significantly higher global connectivity, and changes in edge weights were observed only within the scales. Conclusions: Our findings suggest that the pandemic had a greater disorganising impact at its beginning, with a continuous increase in the mental health symptomatology and a reduction in the ratio between fear and anxiety and/or depression.
