RESUMO: Os padrões paisagísticos em zonas montanhosas com rápido desenvolvimento económico são fortemente afetados por múltiplas atividades humanas. No entanto, as mudanças nas alterações da paisagem nas áreas montanhosas cársticas atribuídas a atividades humanas complexas permanecem obscuras. A investigação sobre o grau de alteração da paisagem em zonas montanhosas sob a influência das atividades humanas é de grande importância para a conservação e gestão científica das paisagens montanhosas. Selecionamos zonas rurais com quatro tipos típicos de acidentes geográficos de pequena escala em áreas montanhosas como objetos de pesquisa e analisamos a resposta das mudanças na perturbação da paisagem rural à atividade humana nessas áreas. Nossos resultados revelam que o grau de alteração da paisagem e a atividade humana influenciam o aumento do índice na maioria das áreas montanhosas. As mudanças na atividade humana e nas perturbações paisagísticas são geralmente observadas na região de baixo relevo do terreno. A utilização intensiva do solo associada ao rápido desenvolvimento econômico tem um sério impacto negativo no grau de perturbação da paisagem, enquanto os projetos de restauração ecológica exercem um impacto positivo. Acelerar a implementação dos projetos para área “verde” e regular a expansão não regulamentada da produção e da terra viva são medidas cruciais para a gestão ecológica em áreas montanhosas cársticas. As futuras estratégias de gestão ecológica deverão centrar-se em áreas de terreno relativamente planas. Nossas descobertas contribuem para a gestão da paisagem e a regulação da atividade humana de diferentes tipos de relevo de pequena escala em áreas montanhosas cársticas.

ABSTRACT: Landscape patterns in mountainous areas with rapid economic development are strongly affected by multiple human activities. However, the changes in landscape disturbances across karst mountainous areas attributed to complex human activities remain unclear. Research on the degree of landscape disturbance in mountainous areas under the influence of human activities is of great significance to the conservation and scientific management of mountainous landscapes. We selected rural zones with four typical small-scale landform types in karst mountainous areas as the research objects and analyzed the response of changes in rural landscape disturbance to human activity in these areas. Our results revealed that the landscape disturbance degree and human activity influence index increase in the majority of karst mountainous areas. The changes in human activity and landscape disturbances are generally observed in the low terrain relief region. High-intensity land use associated with rapid economic development has a serious negative impact on the degree of landscape disturbance, while ecological restoration projects exert a positive impact. Accelerating the implementation of the grain for green project and regulating the unregulated expansion of production and living land are crucial measures for the ecological management in karst mountainous areas. Future ecological management strategies should focus on relatively flat terrain areas. Our findings contributed to the landscape management and human activity regulation of different small-scale landform types in karst mountainous areas.

What motivates voters to support candidates with backgrounds in public security for Brazil’s National Congress, the so-called Law & Order (L&O) politicians? The 2018 elections witnessed a surge in parliamentarians from police and military backgrounds and the election of a president closely aligned with this agenda. We explore whether this trend correlates with municipal-level violence indicators and the presence of municipal capacity in the security sector, employing various regression models that account for socioeconomic, demographic, political, and geographic factors. Our findings from the additive model reveal a negative association between the level of violence and votes for L&O candidates. This suggests a potential disconnection between fear, victimization, and support for repressive policies, while also indicating that local capacity in the security sector tend to enhance L&O candidates’ performance. However, our model incorporating the interaction between both variables uncovers that violence exacerbates the negative impact on L&O voting when the city has capacity in the security sector. This may reflect a municipal-level preference for preventive measures, particularly in more violent areas, which contrasts with the generally repressive stance of L&O candidates.

Resumen Se utilizaron dos modelos gaussianos latentes para medir los efectos de la pobreza sobre la distribución espacial de las tasas de migración municipal durante el período 2015-2020. Para ello, se estimó el saldo migratorio neto a partir de la diferencia entre el número de inmigrantes y emigrantes en áreas geográficas pequeñas, con el objetivo de comprobar la hipótesis de que las personas en situación de pobreza permanecen inmóviles. El saldo migratorio en municipios pobres es significativamente menor al observado en municipios no pobres. Los resultados muestran que un aumento de un punto porcentual en la pobreza municipal incrementaría 1.3 puntos la tasa de migración municipal, sugiriendo que municipios de zonas metropolitanas como la Ciudad de México, Monterrey o Guadalajara, cuyo acceso al empleo y/o a la vivienda es mayor, tienen tasas de inmigración más altas que el promedio nacional.

Abstract Two latent Gaussian models were used to measure the effects of poverty on the spatial distribution of municipal migration rates during the period 2015-2020. To this end, the net migration balance was estimated from the difference between the observed number of immigrants and emigrants in small geographic areas, with the purpose of testing the hypothesis that people in poverty remain immobile. The migration balance observed in poor municipalities is significantly lower than that observed in non-poor municipalities. The results showed that a one percentage point increase in municipal poverty would increase the municipal migration rate by 1.3 points. This suggests that municipalities metropolitan areas such as Mexico City, Monterrey, and Guadalajara, whose access to employment and/or housing is greater, have higher immigration rates than the national average.

Abstract The study of environmental comfort in open urban spaces has undergone constant updates in the last decades. In the meantime, the specific analysis of these aspects within the context of walkability stands out as an area with considerable potential to be investigated. In this context, this article aims to explore walkability in pedestrian routes and its relationship with environmental comfort, proposing a more systematized approach for its application in the strategic planning of cities. Therefore, we proposed the construction of a Pedestrian Walkability and Comfort Index (ICCP), composed of three partial indices that consider thermal, acoustic, and ergonomic aspects of pedestrian paths. The methodology is based on street visualization tools and Geographic Information System (GIS) tools to spatialize and systematize the interactions between walkability and environmental comfort. The research concludes that ICCP is a valid tool for measuring walkability at meso and micro scales, and it can be replicated in other urban contexts. Furthermore, the development and application of ICCP also highlight that rethinking walkability with environmental comfort in urban areas requires an integrated approach to the entire mobility system and urban infrastructure of cities. decades meantime investigated cities Therefore ICCP, , (ICCP) thermal acoustic paths GIS (GIS scales contexts Furthermore (ICCP

Resumo O estudo do conforto ambiental em espaços urbanos abertos está em constante crescimento. Contudo, a análise específica desses aspectos no contexto da caminhabilidade destaca-se como uma área com considerável potencial a ser investigado. Neste contexto, este artigo busca explorar a caminhabilidade nos percursos de pedestres e sua relação com o conforto ambiental, propondo uma abordagem sistematizada para sua aplicação no planejamento urbano estratégico. Propõe-se, assim, a construção de um Índice de Caminhabilidade e Conforto do Pedestre (ICCP) composto por três índices parciais que levam em consideração aspectos térmicos, acústicos e ergonômicos dos percursos de pedestres. A metodologia utilizada é baseada no uso de ferramentas de visualização de ruas e ferramentas de Sistemas de Informação geográfica (SIG) para espacializar e sistematizar as interações entre caminhabilidade e conforto ambiental. A pesquisa conclui que o ICCP se constitui como ferramenta válida para aferição da caminhabilidade na meso e microescalas, podendo ser replicada em outros contextos urbanos. Por último, a construção e aplicação do ICCP evidenciam, ainda, que repensar a caminhabilidade com conforto ambiental no meio urbano requerem uma abordagem integrada de todo o sistema de mobilidade e de infraestrutura urbana das cidades. crescimento Contudo destacase destaca investigado estratégico Propõese, Propõese Propõe se, Propõe-se assim (ICCP térmicos SIG (SIG microescalas último evidenciam ainda cidades

Abstract In this research, we study the real-time development of the assibilation of prepausal /ɾ/ in the Spanish spoken in the state of Guanajuato. For this purpose, we analyze data on the Spanish spoken in the cities of Guanajuato (capital), Pénjamo (southwest), and San Luis de la Paz (northeast) from both a corpus of sociolinguistic interviews collected in 2019 and from interviews conducted in the same towns in 1972-1973 for the Atlas lingüístico de México (Lope Blanch 1990-2000). Our working hypothesis is that assibilation has spread in the state of Guanajuato by relocation. The data provided by both real-time and apparent time have allowed us to corroborate this hypothesis, with San Luis de la Paz being the locality where assibilation is just reaching its greatest vitality. As for other sociolinguistic dimensions of this process, we have once again confirmed that it is women who adopt the assibilant variants of /ɾ/ at the highest rate. Finally, on a purely linguistic level, our findings point to the fact that it is the front vowels /i e/ as a previous phonetic context and the lexical items of verbal category that are the linguistic variables favoring assibilation.

Resumen En esta investigación, se estudia el desarrollo en tiempo real de la asibilación de la /ɾ/ prepausal en el español del estado de Guanajuato. Para ello, se analizaron los datos del español hablado en las ciudades de Guanajuato (capital), Pénjamo (suroeste) y San Luis de la Paz (noreste) provenientes tanto de un corpus de entrevistas sociolingüísticas recogidas en 2019 como de las entrevistas realizadas en las mismas poblaciones en 1972-1973 para el Atlas lingüístico de México (Lope Blanch 1990-2000). Nuestra hipótesis de trabajo es que la asibilación se ha difundido en el estado de Guanajuato por relocalización. Los datos aportados tanto por el tiempo real como por el tiempo aparente nos han permitido corroborar esta hipótesis, siendo San Luis de la Paz la localidad donde la asibilación apenas está alcanzando su mayor vitalidad. En cuanto a otras dimensiones sociolingüísticas de este proceso, hemos confirmado una vez más que son las mujeres quienes patrocinan las variantes asibiladas de /ɾ/. Finalmente, en el plano netamente lingüístico, nuestros hallazgos apuntan a que son las vocales anteriores /i e/ como contexto fónico previo y las piezas léxicas de categoría verbal las variables lingüísticas que favorecen la asibilación.

Resumen La cuenca baja del río Acre se ubica en una zona de deforestación con la implementación de pastizales para ganado vacuno en suelos susceptibles a la erosión y clima ecuatorial. La existencia de mataderos y ganado vacuno en el municipio de Boca do Acre, en el estado de Amazonas, es uno de los problemas vinculados a la deforestación en la Amazonía brasileña. Ante este escenario, se presentó una estimación de las pérdidas de suelo con la aplicación de la Ecuación Universal en un sistema de información geográfica. En la metodología, se desarrolló una base de datos con información vectorizada para extraer las áreas de tipos de suelo y cobertura del suelo, incluyendo el análisis espacial de pendientes extraído del modelo digital de elevación. Como resultado del análisis de las áreas por geoprocesamiento y vectorización, se obtuvieron los cálculos de las parcelas de erosión a través de tablas con los parámetros adoptados por los referentes científicos. Se encontró que el 60% de la pérdida de suelo ocurre en el área agrícola en el 11% del territorio de la cuenca, siendo predominantemente en áreas de asentamientos rurales en el estado de Acre. Como resultado de la estimación, la pérdida de suelo en la cuenca baja del río Acre fue de 386.422 t/ha/año, con una producción de 46 millones de toneladas de sedimentos por año.

Abstract The Lower Acre River Basin is located in an area of deforestation with the implementation of pastures for beef cattle ranching in soils susceptible to erosion and equatorial climate. The existence of slaughterhouses and beef cattle in the municipality of Boca do Acre, in the state of Amazonas, is one of the problems linked to deforestation in the Brazilian Amazon. Given this scenario, an estimate of soil losses was presented with the application of the Universal Equation in a geographic information system. In the methodology, a database was elaborated with vectorized information for the extraction of the areas of the types of soils and land cover, including the spatial analysis of slopes extracted from the digital elevation model. Due to the analysis of the areas by geoprocessing occurring by vectorization, the calculations of the erosion plots were obtained through tables with the parameters adopted by the scientific references. It was found that 60% of the soil loss occurs in the area of agriculture in 11% of the territory of the watershed, being predominantly in areas of rural settlements of the state of Acre. As a result of the estimate, soil loss in the Lower Acre River Basin was 386,422 t/ha/year, with a production of 46 million tons of sediment per year.

Abstract The Comayagua Valley in Honduras, located at coordinates 14˚38’44.73” N and 87˚38’04.90” W, stands out for its altitude of 630 meters above sea level and its dimensions of 52 km in length by 15 km in width, covering an area of 535 km². Despite its economic and connectivity importance, there is a lack of studies addressing its territorial and geomorphological unity and a characterization of its current territorial morphology. The objective of the research is to identify and analyze the shape and natural physical elements that define the Comayagua Valley. To achieve this, Geographic Information Systems tools were used to analyze river layouts, create a digital elevation model, and generate topographic profiles. The main results of this analysis reveal the natural physical elements that shape the valley, which are of vital geo-historical importance for understanding the processes of occupation and land use in the valley.

Abstract Background: Mangroves are communities whose structure expresses patterns according to the coastal landforms in which they develop. Questions: Is there a structural variation of mangroves among landforms and regions of the South Pacific? What is the effect of the geomorphological-regional factor on the structure of mangroves? What is the level of consistency of mangrove structure within each analyzed landform and region? Data description: Basal area, height, density, complexity index, and importance value. Study site: Mangroves from 39 systems in five hydrological regions in the states of Guerrero, Oaxaca, and Chiapas, Mexico. Methods: The structural classification of mangroves was carried out considering the landform (inlet, estuary, lagoon) and the hydrological region. Correlations were used to assess their relationship with salinity and water recharge, and multivariate techniques were employed to identify differences between factors and clustering patterns. Results: Density and basal area correlated positively with water recharge, and it was found that mangrove density and complexity varied significantly among landforms and regions, while basal area and height were affected by landform and region. Discrete groups of variables in ordinations were not evident, with greater structural variability of mangroves found by hydrological region rather than landform. Conclusions: There is structural variation in mangroves among landforms and regions of the South Pacific; however, the variation in basal area, height, and density is low, resulting in consistency when compared across hydrological regions.

Resumen Antecedentes: Los manglares son comunidades cuya estructura expresa patrones de acuerdo a las geoformas costeras en las que se desarrollan. Preguntas: ¿Existe una variación estructural de los manglares entre geoformas y regiones del Pacífico sur? ¿Cuál es el efecto del factor geomórfico-regional sobre la estructura de los manglares? ¿Cuál es el nivel de consistencia de la estructura de los manglares entre cada geoforma y región analizada? Descripción de datos: Área basal, altura, densidad, índice de complejidad y valor de importancia. Sitio de estudio: Manglares de 39 sistemas de cinco regiones hidrológicas en los estados de Guerrero, Oaxaca y Chiapas, México. Métodos: La clasificación estructural de los manglares se realizó considerando la geoforma (bocana, estero, estuario, laguna) y la región hidrológica. Se emplearon correlaciones para evaluar su relación con la salinidad y la recarga hídrica; y técnicas multivariadas para identificar diferencias entre los factores y patrones de agrupación. Resultados: La densidad y el área basal se correlacionaron positivamente con la recarga hídrica, y se encontró que la densidad y la complejidad del manglar variaron significativamente entre geoformas y regiones; mientras que el área basal y la altura fueron afectadas por geoforma y región. Los grupos discretos de las variables en las ordenaciones no resultó evidente, encontrándose mayor variabilidad estructural de los manglares por región hidrológica que por geoforma. Conclusiones: Existe variación estructural en los manglares entre geoformas y regiones del Pacífico sur, sin embargo, la variación del área basal, altura y densidad es baja, resultando consistente al compararse entre regiones hidrológicas.

Abstract Introduction: The COVID-19 epidemic has manifested geographically as clusters of high morbidity (hot zones) and as cold spots of low incidence, which have been explained based on social variables. Objective: To characterize morbidity patterns due to COVID-19 in Costa Rica from March 2020 to May 2022 and to explain them through social determinants of health in the geographical context. Methods: An ecological study at the district level was designed with data on vaccination against COVID-19, weekly reports on speed of advance of the epidemic, development level, and other demographic data. Thematic maps were constructed, and spatial morbidity patterns were identified and characterized, which were explained using linear and geographically weighted regression models. Results: In the Greater Metropolitan Area and surrounding area, clusters of hot spots were identified, and cold spots flanked these high-incidence areas. The linear regression model, built from the variables: average number of vaccines per person, speed in weekly case reporting, social development in its economic, educational, and health dimensions, as well as the proportion of overcrowded homes and people born in the outside, explained more than 70 % of the spatial variations of the incidence of cases (crude and standardized by age and sex). The geographically weighted model corrected autocorrelation problems, improving the explanatory capacity to 82 %. Conclusions: morbidity during the COVID-19 epidemic until May 2020 was configured spatially through well-established clusters of hot and cold spots. This structure could be explained from the social determinants of health, proving that effects on morbidity are generated, differentiated territorially.

Resumen Introducción: En distintos países, la epidemia de covid-19 se ha manifestado en el espacio geográfico como conglomerados de alta morbilidad o zonas calientes, y como conglomerados de puntos fríos de baja incidencia, los que han sido explicados a partir de variables sociales. Objetivo: Caracterizar los patrones la morbilidad de covid-19 en Costa Rica entre marzo del 2020 y mayo del 2022, y explicarlos desde los determinantes sociales de la salud en el contexto geográfico. Métodos: Se diseñó un estudio ecológico a nivel distrital, con datos sobre vacunación contra covid-19, reportes semanales sobre la velocidad de avance de la epidemia, el nivel de desarrollo, y otros datos demográficos. Se construyeron mapas temáticos, se identificaron y caracterizaron los patrones geoespaciales de la morbilidad explicados a partir de modelos de regresión lineal y geográficamente ponderada. Resultados: Se identificaron conglomerados de puntos calientes en la Gran Área Metropolitana y su entorno, y puntos fríos que flanquean esta zona de alta incidencia. El modelo de regresión lineal que incluyó el promedio de vacunas por persona, la velocidad en el reporte de casos semanal, el desarrollo social en sus dimensiones económica, educacional y sanitaria, así como la proporción de viviendas hacinadas y de personas nacidas en el exterior, explicó más del 70 % de las variaciones espaciales de la incidencia de casos (bruta y estandarizada por edad y sexo). El modelo geográficamente ponderado corrigió problemas de autocorrelación mejorando la capacidad explicativa a un 82 %. Conclusiones: La morbilidad durante la epidemia de covid-19, en Costa Rica, durante el período evaluado, se configuró mediante conglomerados espaciales de puntos calientes y fríos muy bien establecidos. Esta estructura se pudo explicar desde los determinantes sociales de la salud, comprobando que se generan efectos en la morbilidad, diferenciados territorialmente.

Abstract Introduction: The Aedes vittatus mosquito is an important vector of yellow fever in Africa, with vectorial competence for dengue, chikungunya and Zika. Its presence has been reported in some places in Africa, Asia, Europe, and -recently- America. However, information on its distribution is fragmented, with limited descriptions of the specific characteristics of its habitats. Objective: To compile records of its occurrence, describe the ecological characteristics of its habitat and estimate its current and future global potential invasion. Methods: We employed both first-record data and global occurrence records to describe its habitat. Additionally, we used an ecological niche model, specifically the MaxEnt algorithm, with bioclimatic variable layers to estimate potential invasion areas. Since the native range of A. vittatus is unknown, we calibrated accessible areas using two hypotheses, Africa and Asia, based on available genetic information. Results: Regardless of its native area, A. vittatus appears to be distributed in tropical and subtropical areas in all continents with potential to reach even currently colder climates as global climate change. It is found mainly in tropical and urban areas, likely through transcontinental and terrestrial passive transport. Conclusions: The mosquito can be found on all continents, ranging from sea level to 2 500 m.a.s.l., at temperatures between 15 and 30 °C, and has the potential for further expansion.

Resumen Introducción: El mosquito Aedes vittatus es un importante vector de la fiebre amarilla en África, con competencia vectorial para el dengue, la chikungunya y el Zika. Se ha informado de su presencia en algunas áreas de África, Asia, Europa y, recientemente, América. Sin embargo, la información sobre su distribución es fragmentada, con descripciones limitadas de las características específicas de sus hábitats. Objetivo: Recopilar registros de su presencia, describir las características ecológicas de su hábitat y estimar su potencial de invasión actual y futuro a nivel mundial. Métodos: Utilizamos datos de primeros registros y registros de presencia a nivel global para describir su hábitat. Además, empleamos un modelo de nicho ecológico, específicamente el algoritmo MaxEnt, con capas de variables bioclimáticas para estimar las áreas de potencial invasión. Dado que se desconoce el área nativa de A. vittatus, calibramos áreas accesibles bajo dos hipótesis, África y Asia, basadas en la información genética disponible. Resultados: Independientemente de su área nativa, A. vittatus parece distribuirse en regiones tropicales y subtropicales en todos los continentes, con el potencial de expandirse incluso hacia climas actualmente más fríos debido al cambio climático global. Se encuentra principalmente en áreas tropicales y urbanas, posiblemente a través del transporte pasivo transcontinental y terrestre. Conclusiones: El mosquito se puede encontrar en todos los continentes, desde el nivel del mar hasta altitudes de 2 500 m.s.n.m., a temperaturas que oscilan entre 15 y 30 °C, y presenta el potencial para una mayor expansión geográfica.

Abstract Objective. To characterize the geographic distribution of dengue and to evaluate the spatial autocorrelation with social and climatic determinants at the census-tract level in two medium sized cities in northwestern Mexico. Methods. In this work we apply spatial analysis ecological tools, such as the Moran’s Index and the Local Indicator of Spatial Association (LISA) method, to examine global and local spatial correlation between incidence of dengue, with socioeconomic and climatic factors at the census tract-level. For the analysis of the spatial clustering, the Getis-Ord method was used to find statistically significant hot spots in each city. Results. Overall, a global spatial autocorrelation could not be identified, although local clusters of a high dengue incidence, soil surface temperature ≤ 31 °C and high degree of social marginalization coincide. Discussion. We found that at the census-tract level in urban settings, socially disadvantaged populations showed higher clusters of dengue when compared to areas with better socioeconomic conditions. A similar spatial pattern was observed in the two study sites, when considering public health conditions and its aggregation with physical attributes using spatial analysis techniques, supporting the application of this technique for a better understanding about the dengue distribution in urban areas.

Resumen Objetivo. Caracterizar la distribución geográfica de dengue confirmado y evaluar su autocorrelación espacial con determinantes sociales y climáticos a nivel de áreas pequeñas, en dos ciudades del noroeste de México. Métodos. En este trabajo se utilizan herramientas de análisis espacial, como el Índice de Moran y el método de Indicadores Locales de Asociación Espacial (LISA), para examinar la correlación espacial, global y local, entre la incidencia de dengue y factores climáticos y socioeconómicos a nivel de área geoestadística básica (AGEB). Para mapear áreas de alto riesgo, se usó el método de agrupamiento espacial de Getis-Ord. Resultados. En general, no identificamos una autocorrelación espacial global, aunque agrupamientos locales de una alta incidencia de dengue, temperatura de la superficie terrestre ≤31 °C y un alto grado de marginación social, coinciden. Discusión. Encontramos que a nivel de áreas pequeñas urbanas, poblaciones con desventaja social agrupan una mayor carga de dengue comparadas con áreas de mejores condiciones socioeconómicas. En los dos sitios de estudio, se encontraron patrones espaciales similares que correlacionaron problemas de salud y características físicas del medio ambiente utilizando os análisis espaciales, lo que soporta la utilidad de su uso sistemático para entender mejor la distribución urbana del dengue.

ABSTRACT Streamflow data from gauging stations are essential for effective water resources management. However, some regions in Brazil lack the necessary data. Hydrological regionalization is an alternative technique for obtaining data such regions. However, not all regions in Brazil have defined hydrological regionalization models, including the state of Goiás and the Brazilian Federal District. The objective of this study was to develop a hydrological regionalization methodology based on the separation of hydrologically homogeneous regions and multiple linear regression, using a Geographic Information System (GIS) program. Historical series data were used to calculate reference flows with 90 or 95% duration over time in the watercourse (Q90 and Q95) and the mean flow (Ǭ). Rain gauge station data were used to calculate the mean annual rainfall in each watershed through spatial interpolation by ordinary kriging. Subsequently, the physiographic characteristics of each watershed were calculated. The hydrologically homogeneous regions were delimited based on these data using cluster analysis, which identified seven hydrologically homogeneous regions in Goiás, two of them belonging to the Federal District. Multiple regression allowed the development of seven regionalization models. Models for regions 1, 3, 4, 5, and 7 showed better performance. management However models District GIS (GIS program 9 95 Q90 Q (Q9 Q95 Ǭ. Ǭ .

RESUMO Para gerenciar os recursos hídricos de forma eficaz, os dados de vazão das estações hidrométricas são cruciais. No entanto, no Brasil, algumas regiões não dispõem dos dados necessários. A regionalização hidrológica é uma técnica alternativa para obter dados para essas regiões. Infelizmente, nem todas as regiões do Brasil têm modelos de regionalização hidrológica definidos, incluindo Goiás e o Distrito Federal. O objetivo deste estudo foi desenvolver uma metodologia de regionalização hidrológica, baseada na separação de regiões hidrologicamente homogêneas e na regressão multivariada, utilizando o programa Sistema de Informações Geográficas (SIG). Com base na série histórica, foram calculadas as vazões de referência com 90 ou 95% de permanência ao longo do tempo no curso d’água (Q90 e Q95) e a vazão média (Ǭ). Com os dados das estações pluviométricas, foi calculada a precipitação média anual de cada uma das bacias hidrográficas fluviométricas, por meio de interpolação espacial por krigagem ordinária. Posteriormente, foram calculadas as características fisiográficas de cada bacia. Com esses dados, as regiões hidrologicamente homogêneas foram delimitadas por meio da análise de agrupamento. A análise de cluster identificou sete regiões hidrologicamente homogêneas em Goiás, sendo que duas delas pertencem ao Distrito Federal. A regressão multivariada levou ao desenvolvimento de sete modelos de regionalização.

This study investigates the role of stable isotope ecology in unconsolidated sediment coastal systems, focusing on scientific production and research trends over time. Existing literature is analyzed to identify knowledge gaps and highlight the significance of stable isotope analysis in understanding coastal ecosystems. A comprehensive bibliometric analysis is employed, utilizing Scopus database to collect and categorize relevant publications on stable isotope ecology. Key indicators are focused on, including publication trends, authorship patterns, and the geographic distribution of research efforts. The temporal scale of studies is systematically analyzed, with attention given to methodological approaches used in these publications. Co-authorships networks and co-occurring keywords are examined to explore the intellectual structure of the field and identify collaborative patterns among authors. Over 140 publications are revealed, attributed to more than 400 researchers, with a significant increase in interest noted over time, particularly in trophic studies involving macrobenthos. Mudflats are identified as a focal point, receiving more attention than sandy beaches. The analysis indicates that seasonality is the predominant temporal scale, while mesoscale studies are observed to be more common in spatial investigations. A plateau in publication growth is noted, probably corresponding with the emergence of alternative methodologies for trophic ecology studies. Major contributions are attributed to France, the United States and Australia. Additionally, fragmented collaboration networks are illustrated through the co-authorship analysis, with limited international engagement among developing nations. Overall, the critical importance of stable isotope ecology in understanding coastal ecosystems is underscored, while the need for methodological diversity and increased collaboration in future research efforts is highlighted.

The main aim of this article is to provide a practical diagnostic approach to phenocopies of Huntington disease (HD). These are defined as conditions characterized by a phenotype similar to HD but with no pathogenic repeat expansion in the HTT gene. Their frequency ranges from 2% to 40% depending on ethnicity and geographic location. The most frequent genetic causes are Huntington Disease-like 2/JHP3, followed by spinocerebellar ataxia genes (SCA17/TBP, SCA12/PPP2R2B and SCA3/ATXN3, CACNA1A), and frontotemporal dementia genes (C9orf72, and VCP). There is current recognition that a growing number of acquired causes can mimic HD. Autoimmune causes such as primary antiphospholipid syndrome, paraneoplastic chorea, and anti-IGLON5 antibodies, as well as stroke, and diabetes mellitus type 2 complications are the leading acquired causes of HD phenocopies. Finally, we provide practical recommendations on how to approach HD phenocopies considering age at onset, ethnicity, and geographic location of individuals.

Abstract: Student socioeconomic segregation is one of the main sources of educational inequity in Argentina. The objective of this paper is to study the explanatory factors of school attendance in privately managed institutions at the secondary level. Furthermore, given the differences in the participation of the private sector by provinces, we particularly aim to compare these determinants to identify possible discrepancies related to geographic location. Some evidence was found that, beyond purchasing power, various social, economic, and cultural characteristics of households are associated with the type of school attended. Moreover, it can be observed that these relationships are not totally homogeneous between the provinces.

Resumen: La segregación del alumnado por nivel socioeconómico es una de las principales fuentes de inequidad educativa en Argentina. El objetivo de este trabajo es estudiar los factores explicativos de la asistencia escolar a instituciones de gestión privada en el nivel secundario.
