Resumen: Dada la prevalencia de los trastornos mentales y los síntomas psicológicos elevados, ha habido un llamado a la acción para ampliar los servicios de salud. Para brindar una atención óptima, es fundamental la detección temprana de los síntomas y la evaluación del estado psicológico. Las medidas de autoinforme tienen una amplia utilidad para evaluar diagnósticos específicos y explorar síntomas psicológicos. El objetivo de este estudio fue aportar nuevas evidencias psicométricas de la versión argentina de la versión breve del Inventario de Síntomas Psicológicos. Mediante un muestreo no probabilístico e intencional, se seleccionaron 760 individuos de 18 a 63 años (M = 28.1; DE = 8.61). A través de análisis factoriales confirmatorios se halló que el modelo de nueve factores correlacionados mostró un mejor ajuste y se encontraron evidencias acerca de su invariancia escalar, métrica y configural según género y región. Los factores mostraron mayormente valores de confiabilidad adecuados, concordantes con investigaciones previas. Se proporcionaron puntajes normativos T. Los resultados mostraron que el instrumento es válido y confiable, y podría ser una herramienta valiosa en diversos contextos, particularmente en la atención primaria, donde la evaluación exige tiempos muy breves e información de utilidad.

Os fatores apresentaram majoritariamente valores de confiabilidade adequados, condizentes com pesquisas anteriores. São fornecidos escores normativos T. Os resultados mostraram que o instrumento é válido e confiável, podendo ser uma ferramenta valiosa em vários contextos, particularmente na atenção primária, onde a avaliação requer tempos muito curtos e informações úteis.

Abstract: Given the prevalence of mental disorders and elevated psychological symptoms, there has been a call for action to scale up health services. To provide optimal care, detecting symptoms early and evaluating the psychological state is essential. Self-report measures are useful to evaluate specific diagnoses and explore psychological symptoms. The present study aimed to provide new psychometric evidence of the Argentine version of the Brief Symptoms Checklist. Through non-probabilistic and intentional sampling, 760 individuals aged 18 to 63 (M = 28.1; SD = 8.61) were selected. Confirmatory factor analysis showed that the nine correlated factors model exhibited the best-fit indices and yielded full configural, metric and scalar invariance across gender and region. The factors mainly showed adequate reliability values similar to previous research. T values are provided as population-based norms. The results showed that the instrument is valid and reliable, and could be a valuable tool in various contexts, particularly in primary care, where the evaluation requires a very short time and useful information.

Conclusiones: El estudio resalta la importancia y utilidad de la Escala de Celos en las relaciones, ya que ayuda a entender cómo funcionan y a saber cómo intervenir. En el futuro, los estudios deben ocuparse de problemas como la selección de participantes y el tipo de estudio realizado, y examinar si la escala se puede usar en diferentes culturas.

Abstract Introduction/Objective: In romantic relationships, jealousy can influence how individuals feel emotionally and interact with their partners. This study analysed the metric properties of the Brief Jealousy Scale (BJS) in young adults from Peru using current methods. Method: A total of 297 individuals were selected to participate in the study. They averaged 26.52 years of age (with a variation of 7.75 years), and 74.10% were women. The study used a technique called Item Response Theory (IRT) with a two-parameter model to confirm the structure and reliability of the BJS. Result: The BJS demonstrated high reliability and fit through goodness-of-fit indices. DIF analysis indicated slight gender biases in some items, reflecting differences in the perception of jealousy between men and women. Conclusions: The study highlights the importance and usefulness of the Jealousy Scale in relationships, as it helps to understand relationship dynamics and guides interventions. Future studies should address issues such as participant selection and study design and examine whether the scale can be used in different cultures.

Abstract The metric dimension of a graph serves a fundamental role in organizing structures of varying dimensions and establishing their foundations through diverse perspectives. Studying symmetric network characteristics like connectedness, diameter, vertex centrality, and complexity depends heavily on the distance parameter. In this article, we explore the exact value for different hexagonal networks' metric dimensions, such as cyclic hexagonal chains, triangular honeycomb mesh, and pencil graphs.

Resumen La dimensión métrica de un grafo cumple un rol fundamental para organizar estructuras de dimensiones variables y establecer sus fundamentos a través de perspectivas diversas. Estudiar características de redes simétricas como la conexidad, diámetro, centralidad de vértices y complejidad depende fuertemente del parámetro de distancia. En este artículo exploramos el valor exacto de la dimensión métrica de diferentes redes hexagonales, tales como cadenas hexagonales cíclicas, la malla triangular panal y grafos lápices.

Abstract Since 2010, there has been an approximate annual increase of 1% in CO2 emissions due to buildings. The reduction of energy consumption and consequently the mitigation of Greenhouse Gases are global goals due to the global issue of climate change. A key step in achieving these goals is to improve the energy performance of buildings, thereby reducing energy consumption and emissions generated by the built environment. In this regard, the present research focuses on identifying and estimating strategies to reduce energy consumption in buildings known as Community Police Units (UPCs) located in the city of Guayaquil, which corresponds to a very hot and humid climate zone. The study consists of statistical analysis of the historical energy performance of 43 buildings sharing the same architectural design. Additionally, the selection of a representative building was made for energy use monitoring and energy simulation. The results revealed a potential saving of 16 000 kWh per year by reducing the control temperature of the air conditioning system by 1°C and adjusting the on/off schedule. This is equivalent to 1 150 USD and 5 metric tons of CO2 emissions.

Resumen: Desde el 2010 existe un incremento aproximado del 1% anual respecto a las emisiones de CO2 a causa de los edificios. La disminución del consumo energético y consecuentemente la mitigación de los Gases de Efecto Invernadero son metas a nivel mundial debido a la problemática global del cambio climático. Un paso clave para alcanzar estas metas es mejorar el desempeño energético de las edificaciones y de esta manera reducir la energía consumida y las emisiones generadas por el parque edificado. En este sentido, la presente investigación se centra en identificación y estimación de estrategias para reducir el consumo de energía de los edificios llamados Unidades de Policía Comunitaria (UPC) localizadas en la ciudad de Guayaquil, y que corresponde a una zona climática húmeda muy calurosa. El estudio está compuesto por el análisis estadístico del rendimiento energético histórico de 43 edificios, que comparten el mismo diseño arquitectónico. Además, se realizó la selección de un edificio representativo para el monitoreo del uso de energía y simulación energética. Los resultados evidenciaron un potencial de ahorro de 16 000 kWh al año, al disminuir 1°C la temperatura de control del sistema de climatización y modificando el horario de encendido y apagado. Esto es equivalente a 1 150 USD y 5 toneladas equivalentes de CO2.

SUMMARY: Morphological dimensions are reliable representations of the functioning, growth, and development of the skeletal- muscular system, defining a significant role in the sport of volleyball. In volleyball, it is imperative to identify the anthropometric constitution generated by endogenous and exogenous factors. The aim of the study was to determine the differences in morphological characteristics between junior and senior members of the BIH national team. The sample of respondents included 29 male volleyball players from the national team of BIH, divided into a subsample of seniors (n=13; Body Height = 194.77 ± 7.01 cm; Body weight = 92.92 ± 7.02 kg) and a subsample of juniors (n=16, Body Height = 197.06±4.65cm; Body weight = 83.19±5.15 kg). Thirteen (13) variables of anthropometric space were measured. Anthropometric measurements were conducted following the ISAK standard procedure guidelines. The standard metric instruments were applied: Stadiometer (SECA 213, Germany) - used for measuring body height; Body mass was measured by a digital scale (Tefal/0-160kg); Circumference measurements were measured with a foldable non-elastic tape measure and a Gullick Tape (Baseline Measurement Tape/300cm) and a Calliper measured skin folds. The T-test results revealed statistically significant differences (approximately 54%) between the senior and junior players in various anthropometric measurements, including weight (T=4.307, p<0.001), leg length (T= - 4.251, p<0.001), hand length (T=2.661, p<0.015), upper arm circumference (T= 4.514, p<0.001), forearm circumference (T=5.275, p<0.001), upper arm skinfold (T= 5.741, p<0.001), and abdominal skinfold (T= 3.098, p<0.009). The male volleyball national team of VIH's senior players displayed superior anthropometric attributes compared to their junior counterparts. Identifying discrepancies at an early stage can optimize both the training regimen and the process of selecting players at a young age.

RESUMEN: Las dimensiones morfológicas son representaciones confiables del funcionamiento, crecimiento y desarrollo del sistema músculo-esquelético, definiendo un papel importante en el deporte del voleibol. En el voleibol es imperativo identificar la constitución antropométrica generada por factores endógenos y exógenos. El objetivo del estudio fue determinar las diferencias en las características morfológicas entre los miembros junior y senior del equipo nacional de BIH. La muestra de encuestados incluyó 29 jugadores de sexo masculino de voleibol del equipo nacional de BIH, divididos en una submuestra de mayores (n=13; altura corporal = 194,77 ± 7,01 cm; peso corporal = 92,92 ± 7,02 kg) y una submuestra de juveniles (n =16, Altura corporal = 197,06±4,65 cm; Peso corporal = 83,19±5,15 kg). Se midieron trece (13) variables del espacio antropométrico. Las mediciones antropométricas se realizaron siguiendo las pautas de procedimiento estándar de ISAK. Se aplicaron los instrumentos métricos estándar: estadiómetro (SECA 213, Alemania), utilizado para medir la altura corporal; La masa corporal se midió con una báscula digital (Tefal/ 0-160 kg); Las mediciones de la circunferencia se midieron con una cinta métrica plegable no elástica y una cinta Gullick (cinta métrica de referencia/300 cm) y un calibrador midió los pliegues de la piel. Los resultados de la prueba T revelaron diferencias estadísticamente significativas (aproximadamente 54 %) entre los jugadores senior y junior en varias medidas antropométricas, incluido el peso (T=4,307, p<0,001), la longitud de las piernas (T= -4,251, p<0,001), longitud de la mano (T=2,661, p<0,015), circunferencia del brazo (T= 4,514, p<0,001), circunferencia del antebrazo (T=5,275, p<0,001), pliegue cutáneo del brazo (T= 5,741, p<0,001), y pliegue cutáneo abdominal (T= 3,098, p<0,009). Los jugadores senior del equipo nacional masculino de voleibol de VIH mostraron atributos antropométricos superiores en comparación con sus homólogos juveniles. Identificar discrepancias en una etapa temprana puede optimizar tanto el régimen de entrenamiento como el proceso de selección de jugadores a una edad temprana.

ABSTRACT This contribution presents the study of an Ordovician subaqueous felsic succession, formed by the ~400 m-thick Upper Member of the Cordón de Lila Complex (CISL), northern Chile. From bottom to top, the succession starts with two dacitic sills that intruded into the sediments of the lowermost part of the Upper Member. Then, it is followed by a thick sedimentary deposit, two rhyolitic lavas, a volcanoclastic felsic breccia with pyroclastic clasts, and ends with a red rhyolitic lava. The first rhyolitic lava shows centimetric to metric folds with a north-northwestern vergence, evidence of flow in that direction. In the volcanoclastic breccia, an abundant pumice-and-fiamme-rich green matrix wraps around lithic clasts, giving the rock an eutaxitic texture at the outcrop scale. This matrix and texture evidence is characteristic of hot pyroclastic flows deposited under subaqueous conditions. The described section of the breccia is formed by four coarsening-up sequences, reflecting respectively four pulses of building up energy. The lack of internal erosional features points to a single and continuous explosive eruption. An accidental granite clast in the upper part of the breccia suggests a connection with a granitic body, possibly the Pingo-Pingo monzogranite. The geochemical character of the felsic succession is calc-alkaline. The tectonic setting diagram shows a within-plate setting for the succession. This suggests a shift from the arc position inferred for the Lower Member of the CISL to a forearc continental setting for the Upper Member of the CISL.

RESUMEN Este trabajo presenta una sucesión subacuática félsica ordovícica, formada por el miembro superior del Complejo ígneo-sedimentario del Cordón de Lila (CISL), el que posee un espesor de ~400 m. De base a techo, la sucesión incluye dos filones-manto dacíticos, intruidos en sedimentos de la parte inferior de dicho miembro. Luego presenta un intervalo de sedimentitas, dos lavas riolíticas y una brecha volcanoclástica félsica con clastos piroclásticos. La secuencia finaliza con una lava riolítica rojiza. El primer flujo de lava riolítica contiene pliegues métricos a centimétricos con vergencia hacia el nornoroeste, lo que indica un flujo en ese sentido. La brecha tiene una abundante matriz verdosa formada por fiamme y pómez soldadas que rodean a los clastos líticos, y otorgan a la brecha una conspicua textura eutaxítica. El tipo de matriz y la textura observadas son características de flujos piroclásticos calientes depositados en ambientes submarinos. La sección descrita de la brecha puede dividirse en cuatro secuencias granocrecientes, las cuales reflejan, respectivamente, cuatro pulsos de energía creciente. La ausencia de discontinuidades internas apunta a una única erupción explosiva. La presencia de un clasto accidental de granito en la brecha sugiere una conexión con un intrusivo granítico en profundidad, posiblemente el monzogranito Pingo-Pingo. La afinidad geoquímica de la sucesión es calcoalcalina. En el diagrama de ambientes tectónicos, las volcanitas del miembro superior caen dentro del campo de intraplaca. Esto sugiere un cambio desde un ambiente de arco volcánico para el miembro inferior del CISL a una posición de antearco continental para el miembro superior del CISL.

Since discovery and description of the species, Sahelanthropus tchadensis has been at the centre of a great discussion around its classification as a hominin - the first of our lineage - or an ape. Many studies have been conducted in order to clarify this question, especially studies based on the morphology of the cranium and the post-cranial remains. In this study, we analysed the posterior dentition of S. tchadensis in relation to those of other hominins and chimpanzees, using a multivariate comparative metric analysis. Our results suggest that the posterior dentition of the Chad material lies in the range of well-established early Plio-Pleistocene hominins, supporting its classification as part of the hominin lineage. SIGNIFICANCE: • The subject investigated in this study is important to the understanding of the first steps of human evolution. • Much has been discussed about this Chadian species. Some believe it is the first hominin, others believe it is an ape. • This study shows that the posterior dentition of S. tchadensis does not preclude it from being a hominin.

Internationally, there has been a push for the prioritisation of research impact beyond its scholarly contribution. Traditionally, research impact assessments have focused on academic impact and quantitative measures, at the expense of researchers for whom research impact cannot be quantified. Bibliometric indicators and other quantitative measures are still the most widely used method for evaluating research impact because these measures are easy to use and provide a quick solution for evaluators. Conversely, metric indicators fail to capture important dimensions of high-quality research. Hence, in this study, we explored challenges with metric indicators. We adopted a case study of the University of Cape Town and used document analysis, a questionnaire survey to collect data from academics and researchers, as well as semi-structured interviews with a sample of academic and research staff. The findings highlight common challenges with quantitative measures, such as bias and discipline coverage, and the ability of measures to drive researchers' behaviour in another direction. We propose the adoption of responsible research metrics and assessment in South African higher education institutions for more inclusive and equitable research impact assessments. SIGNIFICANCE: • The study highlights the importance of understanding the challenges and influence of current measures used for assessing research impact in higher education institutions. • There is a need for higher education leaders, policymakers and funders to advocate and support responsible metrics. • Higher education leaders, funders and policymakers need to collaborate at the national level to initiate and support research assessment reform.

Resumen La efectividad de las políticas implementadas durante la pandemia del COVID-19 es relevante, tanto para evaluar el impacto ocasionado, como para derivar lecciones de política en el caso de que este tipo de fenómenos se repitan. El objetivo de este documento es determinar la relación entre la actividad humana y los contagios de COVID-19 reportados. Para medir la actividad humana se genera una métrica de luminosidad nocturna empleando imágenes satelitales. Mediante un análisis de cointegración se demuestra que existe de una relación de equilibrio a largo plazo y, empleando pruebas de causalidad, que es factible predecir los contagios por COVID-19 a partir de los cambios en la luminosidad. Con modelos econométricos para series de tiempo se demuestra que los contagios por COVID-19 responden a los cambios de luminosidad con alta significancia estadística y hasta con dos semanas de retraso, esto implica que la intensidad de la actividad que sucedía en el momento presente habría sido útil para planificar los recursos que serían necesarios dos semanas posteriores.

Abstract The effectiveness of the policies implemented during the COVID-19 pandemic is relevant both for assessing the impact caused and for deriving policy lessons in case such phenomena recur. The main objective here is to determine the relationship between human activity and reported COVID-19 cases. To measure human activity, a metric of nighttime lights is generated using satellite images. Conducting cointegration tests we found a long-term equilibrium relationship between the two variables, and through causality tests we confirmed that it is feasible to predict COVID-19 infections from changes in nighttime lights. Using econometric models for time series, it is shown that COVID-19 infections respond to changes in nighttime lights with high statistical significance and with a lag of up to two weeks, implying that the intensity of human activity that was happening now would have been useful for planning the resources that would be necessary two weeks later.

Abstract Purpose. The purpose of this paper is to compare nine different models to evaluate consumer credit risk, which are the following: Logistic Regression (LR), Naive Bayes (NB), Linear Discriminant Analysis (LDA), k-Nearest Neighbor (k-NN), Support Vector Machine (SVM), Classification and Regression Tree (CART), Artificial Neural Network (ANN), Random Forest (RF) and Gradient Boosting Decision Tree (GBDT) in Peer-to-Peer (P2P) Lending. Design/methodology/approach. The author uses data from P2P Lending Club (LC) to assess the efficiency of a variety of classification models across different economic scenarios and to compare the ranking results of credit risk models in P2P lending through three families of evaluation metrics. Findings. The results from this research indicate that the risk classification models in the 2013-2019 economic period show greater measurement efficiency than for the difficult 2007-2012 period. Besides, the results of ranking models for predicting default risk show that GBDT is the best model for most of the metrics or metric families included in the study. The findings of this study also support the results of Tsai et al. (2014) and Teplý and Polena (2019) that LR, ANN and LDA models classify loan applications quite stably and accurately, while CART, k-NN and NB show the worst performance when predicting borrower default risk on P2P loan data. Originality/value . The main contributions of the research to the empirical literature review include: comparing nine prediction models of consumer loan application risk through statistical and machine learning algorithms evaluated by the performance measures according to three separate families of metrics (threshold, ranking and probabilistic metrics) that are consistent with the existing data characteristics of the LC lending platform through two periods of reviewing the current economic situation and platform development.

Abstract Purpose. This paper proposes a methodology based on an uncertain mining technology that identifies the linguistic relationships of ESG and its components with a financial performance metric to help the sustainability diagnosis of a region, specifically Latin America. Design/methodology/approach. First, based on a relevant dataset of companies in a region, a procedure is formulated whereby an uncertain mining technology extracts the mathematically significant linguistic relationships of ESG and its components with a financial performance metric. Second, a knowledge management process is designed based on the linguistic summaries obtained from the mining process. As a final step and drawing upon the two preceding processes, a diagrammatic system of signals is proposed for diagnosing the sustainability of the region as contributed by its companies. Findings. After this methodology is instantiated on a group of Multilatinas, it is observed that their sustainability contributions to the region are limited and that none of the identified linguistic relationships between ESG and the financial performance metric are favorable for the region. Originality/value. This is the first proposal of its kind and it can be applied to any region of the world to assess the financial performance of its companies regarding their ESG commitments. In addition, it enables the region to comprehensively monitor compliance with the 2030 SDG agenda.

Abstract Introduction: Repetitive Negative Thinking (RNT) can be characterized as intrusive thoughts about worries (current, past, or future), negative experiences, and self-criticism, manifesting excessively and persistently. In a transdiagnostic process, it is identified that the RNT contributes to the onset and maintenance of multiple disorders. The present study aimed to adapt the Persistent and Intrusive Negative Thoughts Scale (PINTS) for the Brazilian context, investigating the psychometric qualities of the instrument. Method: Two studies were carried out with participants from different Brazilian states. In Study 1 (n = 258), the adaptation of PINTS and an exploratory factor analysis was performed. In Study 2 (n = 270), a confirmatory factor analysis was conducted, and evidence of convergent validity was gathered. Results: Firstly, in Study 1, a unifactorial structure of the measure was indicated. Through Study 2, the unifactorial structure was corroborated, demonstrating adequate internal consistency (precision), demonstrating that PINTS positively correlated with negative affectivity (stress, anxiety, and depression) and cognitive test anxiety. Conclusion: It is concluded that PINTS exhibited satisfactory metric qualities, being a brief and easy-to-administer measure, potentially serving as a useful tool for researchers investigating maladaptive repetitive negative thinking and its correlates.

Resumo Introdução: o pensamento repetitivo negativo (PRN) pode ser caracterizado como pensamentos intrusivos sobre preocupações (atuais, passadas ou futuras), experiências negativas e autocríticas, manifestando-se de forma excessiva e persistente. Em um processo transdiagnóstico, identifica-se que o PRN contribui para o aparecimento e manutenção de transtornos múltiplos. O presente estudo objetivou adaptar a Persistent and Intrusive Negative Thoughts Scale (PINTS) para o contexto brasileiro, averiguando as qualidades psicométricas do instrumento. Método: procedeu-se a dois estudos com participantes de diferentes estados brasileiros. No estudo 1 (n = 258), foi realizada a adaptação da PINTS e uma análise fatorial exploratória. No estudo 2, (n = 270), foi realizada uma análise fatorial confirmatória além de reunidas evidências de validade convergente. Resultados: primeiramente, o estudo 1 apontou uma estrutura unifatorial da medida. A partir do estudo 2, foram corroboradas a estrutura unifatorial e a adequada consistência interna (precisão), o que demonstrou que a PINTS se relacionou positivamente com a afetividade negativa (estresse, ansiedade e depressão) e com a ansiedade cognitiva de provas. Conclusão: conclui-se que a PINTS apresentou qualidades métricas satisfatórias, sendo uma medida curta e de fácil aplicação, podendo ser uma ferramenta útil para pesquisadores que buscam investigar o PRN desadaptativo e os seus correlatos.
