Primer registro de Leopardus braccatus (Carnivora: Felidae) en el bosque seco chiquitano, Bolivia Nogales Ascarrunz, Paola; Aramayo Ledezma, Gabriel; Aliaga Rossel, Enzo; Aramayo Bejarano, José Luis; Lucherini, Mauro; Jansen, Martin El complejo del Leopardus colocolo, según una reciente actualización taxonómica, ha sido dividido en cinco especies. Una de estas es Leopardus braccatus conocida como gato del pantanal, distribuido en Bolivia, Brasil y Paraguay. A pesar de su distribución, esta es una especie poco estudiada. Presentamos aquí un nuevo registro de esta especie, siendo el primero registrado en el bosque seco chiquitano, un ecosistema amenazado que previamente no se consideraba su hábitat. Este hallazgo se llevó a cabo como parte de un programa de monitoreo de felinos con cámaras trampa, donde adicionalmente seis especies de félidos fueron detectadas en un área de 41km2, lo que indica una alta diversidad de felinos en esta ecorregión. Además, se identificaron amenazas directas para el gato del pantanal, como la actividad agrícola y ganadera, los perros domésticos y la cacería ilegal. La relevancia de este nuevo registro radica en su ubicación en el límite occidental-sur de la distribución conocida para Bolivia, así también como sus características morfológicas similares a la especie L. munoai. Esto subraya la necesidad de realizar investigaciones adicionales para comprender mejor su distribución y conservación. Estudios futuros podrían explorar también las similitudes morfológicas y de distribución entre L. braccatus y L. munoai.; The Leopardus colocolo complex, according to a recent taxonomic update, has been divided into five species. One of these is Leopardus braccatus, known as the Pantanal cat, distributed in Bolivia, Brazil, and Paraguay. Despite its distribution, this species remains understudied. Here, we present a new record of this species, the first documented in the dry Chiquitano forest, a threatened ecosystem previously not considered its habitat. This finding was part of a wild felid camera trap monitoring program using camera traps, where additionally six species of felids were detected in a 41km2 area, indicating high felid diversity in this ecoregion. Furthermore, direct threats to the Pantanal cat were identified, such as agricultural activity, presence of livestock, domestic dogs, and illegal hunting. The significance of this new record lies in its location at the southwestern limit of the known distribution for Bolivia, as well as its morphological similarities to the species L. munoai. This underscores the need for further research to better understand its distribution and conservation. Future studies could also explore morphological and distributional similarities between L. braccatus and L. munoai.

A rhodium-catalyzed C–H activation/cyclization approach toward the total syntheses of cassiarin C and 8- O -methylcassiarin A from a common intermediate Vargas Vargas, Didier Farley; Fonzo, Santiago; Simonetti, Sebastián Osvaldo; Kaufman, Teodoro Saul; Larghi, Enrique Leandro Three short and efficient total syntheses of cassiarin C are reported, from a chromanone common key intermediate. A C–H activation strategy, under rhodium catalysis on its pivaloyl oxime, enabled the installation of the pyridine ring. Dehydrogenation of 8-O-methylcassiarin C afforded 8-O-methylcassiarin A. A kinetic experiment and DFT calculations of the intermediates helped to gain insight into the unusual siteand stereo-specific H/D exchange of cassiarin C in CD3OD.

CONICET Digital -

Current understanding, knowledge gaps, and challenges of mountain permafrost research in the Chilean and Argentinean Andes Fernández Navarro, Hans; Tapia Baldis, Carla Cintia; Rojas, Claudia; Derrien, Morgane; Villaseñor, Tania Mountain permafrost extends over a vast area throughout the Chilean and Argentinean Andes, making it a key component of these mountain ecosystems. To develop an overview of the current state of knowledge on southern Andean permafrost it is essential to outline appropriate research strategies in a warmer climate context . Based on a comprehensive review of existing literature, this work identifies eight main research themes on mountain permafrost in the Chilean and Argentinean Andes: paleoenvironmental reconstructions, rock glacier inventories, permafrost distribution models, internal structure analysis, hydrogeochemistry, permafrost dynamics, geological hazards, and transitional landscape studies. This extensive review work also highlights key debates concerning the potential of permafrost as a water resource and the factors influencing its distribution. Furthermore, we identified several challenges the scientific community must address to gain a deeper understanding of mountain permafrost dynamics. Among these challenges, we suggest tackling the need to broaden spatial focus, along with the use of emerging technologies and methodologies. Additionally, we emphasize the importance of developing interdisciplinary approaches to effectively identify the impacts of climate change on mountain permafrost. Such efforts are essential for adequately preparing scientists, institutional entities, and society to address future scenarios.

Burial Histories, Bodies, and Pots: Mortuary Practices in the Southeastern Rainforests of the Andes during the 1st Millennium a.d. (El Cadillal, Argentina)

CONICET Digital -

Burial Histories, Bodies, and Pots: Mortuary Practices in the Southeastern Rainforests of the Andes during the 1st Millennium a.d. (El Cadillal, Argentina) Vazquez Fiorani, Agustina; Kuijt, Ian; Salazar, Julián Through the control of social memory and the dead, household members in Argentinian Andeanearly Formative villages often used primary and secondary mortuary practices to negotiate powerand identity among the living. In this paper, we explore the material evidence obtained in thelarge-scale salvage excavations of El Cadillal, Argentina, where 51 burials were recovered fromthree burial sites. Between A.D. 0 and 900, people living in the southeastern rainforests placeddeceased household members in ceramic urns and, less frequently, inside of rock enclosures andpits surrounded by a range of grave offerings. Drawing upon this case study, we attempt todisentangle the complex web of relationships between the dead, the living, and the El Cadillalcommunity in order to assess how social memories were crafted through primary and secondarymortuary events and how the repetition of mortuary rituals created a social landscape andmemories of the dead.

Caracterización hidroambiental de cuencas en la Reserva Parque Costero del Sur, Argentina; Hydro-environmental characterization of watersheds within the Parque Costero Sur Reserve, Argentina Glustein, Jazmín Ilana; Arturi, Tatiana Sonia; Berardozzi, Eliana; Delgado, María Isabel A pesar de existir una relativa homogeneidad en diferentes característicasde la región pampeana, el tipo de suelo podría determinar los usosposibles en cada zona, con impactos variables en la hidrología, la químicadel agua, la morfología de los cursos y la biodiversidad. En las reservasde biosfera resulta fundamental generar conocimiento que ayude acomprender la relación entre las actividades productivas desarrolladas yel estado de los ecosistemas. El objetivo de este trabajo es caracterizarlas cuencas hidrográficas dentro de la reserva Parque Costero del Sur afin de aportar al desarrollo de una interpretación conceptual delfuncionamiento hidrológico en este territorio. Se estudiaron tres arroyos-Buñirigo, Juan Blanco y Villoldo- con diferentes grados de intervenciónantrópica. Para ello se caracterizaron morfométricamente sus cuencas, segeneraron mapas de uso del suelo y se realizaron balances hídricos. Sellevaron a cabo dos campañas de muestreo de agua superficial y análisisde parámetros fisicoquímicos y microbiológicos. La diferencia en laconcentración de estos parámetros entre campañas resultó significativa.En todos los casos, los valores de Conductividad Eléctrica (CE), turbidezy Demanda Química de Oxígeno (DQO) fueron mayores durante el períodode déficit y los de Fósforo Reactivo Soluble (PRS) durante el período deexceso hídrico. En cambio, la asociación con la distribución espacial de los sitios de muestreo no reveló tendencias claras. Esta investigación podríaresultar útil para la toma de decisiones relacionadas con la gestión delrecurso hídrico, ya que ciertos parámetros exceden los límitesestablecidos localmente.; Despite the relative homogeneity in different characteristics of the Pampas region, the soil type might determine the possible land uses in each area, with variable impacts on hydrology, water chemistry, watercourse morphology, and biodiversity. In biosphere reserves, it is crucial to generate knowledge that helps to understand the relationship between productive activities and the state of the supporting ecosystems. The objective of this study is to characterize the watersheds within the Parque Costero del Sur reserve to contribute to the development of a conceptual interpretation of the hydrological functioning in this territory. Three streams -Buñirigo, Juan Blanco, and Villoldo- with different degrees of anthropic intervention were studied. To achieve this, their watersheds were morphometrically characterized, land-use maps were generated, and water balances were conducted. Two surface water sampling campaigns were carried out, analyzing physicochemical and microbiological parameters. The difference between campaigns for the concentration of these parameters was significant. In every case, the values of Electrical Conductivity (EC), turbidity, and Chemical Oxygen Demand (COD) were higher during the deficit water period and Soluble Reactive Phosphorus (SRP) values during the excess water period. Instead, no clear trends were found regarding the association with the spatial distribution of the sampling sites along the watersheds. This research might be useful for decision-making related to water resource management, as certain parameters exceed locally established thresholds.

Selective lithium extraction employing lithium manganese oxide-loaded polymeric membranes at natural brine pH and room temperature

CONICET Digital -

Selective lithium extraction employing lithium manganese oxide-loaded polymeric membranes at natural brine pH and room temperature Arrua, Eva Carolina; Bedogni, Giselle Rocio; Salomon, Claudio Javier; Flexer, Victoria The current technology for lithium extraction from brines is recognized both for its techno-economic disadvantages and its environmental impacts. We have synthesized, characterized, and evaluated particles based on lithium manganese oxide towards selective lithium recovery from complex media. A solid-state synthesis and a hydrothermal method produced sub-micrometre sized particles that showed diameters of 253 nm and 154 nm, respectively, both with very low polydispersity. 23.7 mgLi/gHMO and 30.7 mgLi/gHMO adsorption capacity values were obtained with solid-state synthetic and hydrothermal oxides. The hydrothermally synthesized submicrometre sized particles were incorporated into polymeric membranes aiming at the development of a straightforward technological application. Membranes were prepared from polyacrylonitrile and polyethyleneglycol, and the affinity to lithium was once again evaluated. Membranes showed a high adsorption capacity for lithium (32.7 mgLi/gHMO) with almost identical kinetics and cyclability as the free particles in solution. An excellent selectivity for lithium was confirmed in experiments with a natural lithium-rich brine from the Lithium Triangle. All adsorption experiments were performed at neutral pH and room temperature. An undeniable advantage of membranes vs. sub-micrometre sized particles is that the former do not require centrifugation after successful adsorption/desorption. These three characteristics are fundamental in the perspective of technology scale-up to minimize operational costs.

CONICET Digital -

La vida afectiva en el arte independiente: Territorio sensible en la danza contemporánea del interior provinciano; Affective life in independent art: Sensitive territory in contemporary dance of the provincial interior Bertea, Francisco Miguel Fernando En este trabajo indagamos la vida afectiva en el arte independiente, específicamente en el mundo de la danza contemporánea del Valle de Paravachasca (Córdoba, Argentina), a partir de un trabajo etnográfico colaborativo de participación observante en el grupo Cantorodado, entre los años 2018-2022. Situados en los estudios sociales del arte y el giro afectivo, describimos de forma densa el territorio sensible de este mundo del arte, distinguiendo algunos de los vectores que lo componen, en calidad de tipos reales: una forma de (ganarse la) vida colectiva, una ética del cuidado y una atmósfera afectiva de entusiasmo. Empleamos para ello una propuesta analítica que se mueve en la tensión entre analítica-individuo y analítica-fuerza, entre las libertades relativas de los agentes y las estructuras estructurantes de sujeción. Realizamos así aportes a la comprensión de la vida afectiva de la danza contemporánea independiente y al arte independiente como forma de (ganarse la) vida, desde temáticas específicas, como la moral, la amistad, el management, el wellness y el don, reconociendo que la propuesta analítica empleada puede significar un aporte al estudio de la vida afectiva.; In this paper we investigate the affective life in independent art, specifically in the contemporary dance world of the Paravachasca Valley (Córdoba, Argentina), from a collaborative ethnographic work of observant participation in the Cantorodado group, between the years 2018-2022. Situated in the Social Studies of Art and the affective turn, we make a thick description of the sensitive territory of this art world, distinguishing some of the vectors that compose it, as real types: a way of (earning the) collective life, an ethic of care and an affective atmosphere of enthusiasm. We use an analytical proposal that moves in the tension between analytic-individual and analytic-force, between the relative freedoms of the agents and the structuring structures of subjection. We contribute at the understanding of the affective life of independent contemporary dance and independent art as a way of (earning a) living, from specific aspects linked: morality, friendship, management, wellness and gift. Acknowledging that the analytical proposal used can mean a contribution to the study of the affective life.

Use of cannabidiol-dominant extract as co-adjuvant therapy for type 2 diabetes mellitus treatment in feline: case report

CONICET Digital -

Use of cannabidiol-dominant extract as co-adjuvant therapy for type 2 diabetes mellitus treatment in feline: case report Massabo, José Ignacio; Puiatti, Gabriela; Ferrero, Paola Viviana Introduction: Diabetes mellitus (DM) is a common endocrinopathy in felines. Treatment is based on glycemic control and management of clinical signs by insulin administration coupled with a low-carbohydrate and high-protein content diet. However, achieving adequate remission or glycemia control is not always possible. Effects of cannabinoids on the regulation of glucose uptake and the incidence of diabetes have been observed in experimental models. Nevertheless, little is known about their possible relevance in controlling this condition in veterinary and human medicine. Case presentation: This is a case study of an 18-year-old, neutered, mixed-breed female domestic longhair cat diagnosed with type 2 diabetes mellitus. She was treated with long-acting glargine (3 to 5 IU/12 hs), and her diet changed to ultra-processed commercial food for diabetic cats. Three months after the start of the treatment with insulin, Cannabidiol (CBD)-enriched extract in handmade olive oil, THC: CBD ratio = 1:24, was incorporated. The route of administration was oromucosal. After three months, the glycemia was reduced. The patient decreased the polyuria/polydipsia, recovered sleep cycles, remained attentive to all movements, and increased her physical activity. Conclusion: This report provides evidence that using a CBD-rich extract was effective as a co-adjuvant in alleviating clinical signs of DM and concurrent disorders, allowing for the reduction of insulin intake.

Revisiting the massive star-forming complex RCW 122: New millimeter and submillimeter study

CONICET Digital -

Revisiting the massive star-forming complex RCW 122: New millimeter and submillimeter study Duronea, Nicolas Urbano; Bronfman, L.; Ortega, Martin Eduardo; Suad, Laura Andrea; Baume, Gustavo Luis; Mendoza, E.; Carvajal, M.; Cichowolski, Silvina; Arnal, Edmundo Marcelo; Finger, R.; Merello, M.; Gamen, Roberto Claudio In this paper, we present a new multifrequency study of the giant star-forming complex RCW 122. We used molecular data obtained with the ASTE 10 m and the APEX 12 m telescopes, along with infrared observations spanning from 3.6 µm to 870 µm, obtained from available databases. We also incorporated a range of public datasets, including the radio continuum at 3 GHz, narrowband Ha images, and deep JHK photometry. Our analysis focuses mostly on cataloged ATLASGAL sources, showcasing a spectrum of evolutionary stages from infrared dark cloud (IRDC)/high-mass protostellar object (HMPO) to ultra-compact HII region (UCHII), as inferred from preliminary inspections of the public dataset. Based on ASTE HCO+(4‑3) and CO(3‑2) data, we identified five molecular clumps, designated A, B, C, D, and E, as molecular counterparts of the ATLASGAL sources. These clumps have radial velocities ranging from ~‑15 km s‑1 to ‑10 km s‑1, confirming their association with RCW 122. In addition, we report the detection of 20 transitions from 11 distinct molecules in the APEX spectra in the frequency ranges from 258.38 GHz to 262.38 GHz, 228.538 GHz to 232.538 GHz, and 218.3 GHz to 222.3 GHz, unveiling a diverse chemical complexity among the clumps. Utilizing CO(2‑1) and C18O(2‑1) data taken from the observations with the APEX telescope, we estimated the total LTE molecular mass, ranging from 200 M⊙ (clump A) to 4400 M⊙ (clump B). Our mid- to far-infrared (MIR-FIR) flux density analysis yielded minimum dust temperatures of 23.7 K (clump A) to maximum temperatures of 33.9 K (clump B), indicating varying degrees of internal heating among the clumps. The bolometric luminosities span 1.7×103 L⊙ (clump A) to 2.4×105 L⊙ (clump B), while the total (dust+gas) mass ranges from 350 M⊙ (clump A) to 3800 M⊙ (clump B). Our analysis of the molecular line richness, L/M ratios, and CH3CCH and dust temperatures reveals an evolutionary sequence of A/E→C→D/B, consistent with preliminary inferences of the ATLASGAL sources. In this context, clumps A and E exhibit early stages of collapse, with clump A likely in an early HMPO phase, which is supported by identifying a candidate molecular outflow. Clump E appears to be in an intermediate stage between IRDC and HMPO. Clumps D and B show evidence of being in the UCHII phase, with clump B likely more advanced. Clump C likely represents an intermediate stage between HMPO and HMC. Our findings suggest clump B is undergoing ionization and heating by multiple stellar and protostellar members of the stellar cluster DBS 119. Meanwhile, other cluster members may be responsible for ionizing other regions of RCW 122 that have evolved into fully developed HII regions, beyond the molecular dissociation stage.

Flexible and configurable embedded electrical energy measurement system to acquire and process high-frequency features

CONICET Digital -

Flexible and configurable embedded electrical energy measurement system to acquire and process high-frequency features Véliz, Maximiliano Ezequiel; Real, Gustavo Ernesto; Otero, Alejandro Daniel A novel High-Frequency Electric Energy Metering System to inspect non-conventional features that may be relevant for studying real-time energy disaggregation and control of household appliances is presented. Integration of a data acquisition and control board, designed and built to be assembled with an Arduino Due, with the M90E36A Demo Board, allows for flexible and configurable electrical energy measurements. A key feature is that up to 4 current channels can be measured synchronously. On the one hand, samples can be obtained and processed by the M90E36A IC internal Digital Signal Processor at 3 Hz in the time domain and 2 Hz in the frequency domain. On the other hand, the M90E36A IC direct access memory mode can be operated, allowing 8 kHz pure voltage and current signals to be obtained. Finally, integration with Raspberry Pi allows to design and incorporate a custom signal processor into the study. Additionally, in this article, an application example is presented where the variation of the residual harmonic components of a household appliance is obtained.

Characterising cricket flour from Gryllus assimilis : an alternative source of nutrients for sustainability

CONICET Digital -

Characterising cricket flour from Gryllus assimilis : an alternative source of nutrients for sustainability Toribio, Ezequiel; Correa, María Jimena; Medici, Sandra Karina; Ferrero, Cristina; Arp, Carlos Gabriel A trend to study entomological options as food is turning the practice of entomophagy into a novelresearch field in search for sustainable and accessible sources of nutrients. In this work, cricket (Gryllus assimilis) was processed into flour (CF), and then extracted using different solvents to obtain oils and defatted flours. The repeatability of CF obtention, its nutritional profile, and some of its physicochemical properties were studied. Results showed repeatability with a 28% mass yield for CF production. The CF presented adequate amino acid, mineral, and fatty acid profiles, a high content of dietary fibre, and low available carbohydrates, thus being considered a suitable alternative for inclusion in healthy human diets. Using data obtained from the total nitrogen content, the amino acid profile, and the total dietary fibre determinations, the CF protein digestibility was estimated at 67.4%. Based on experimental data, a mean nitrogen-to-protein conversion factor of 5.76 was calculated for a G. assimilis meal. The study showed that nutritional cricket flour and derivatives can be obtained using non-sophisticated methods.

A Decade of Monitoring Primary Healthcare Experiences through the Lens of Inequality

CONICET Digital -

A Decade of Monitoring Primary Healthcare Experiences through the Lens of Inequality Pasarín, M. Isabel; Rodríguez Sanz, Maica; Berra, Silvina del Valle; Borrell, Carme; Rocha, Kátia B. Background: Health care is not exempt from harboring social inequalities, including in those countries with a universal public system. The objective was to ascertain whether the population’s assessment of primary care (PC) changed between 2006 and 2016, the decade that included the economic crisis of 2008, and also if it exhibited patterns of social inequality in Barcelona (Spain). Methods: This was a cross-sectional study using Barcelona Health Surveys 2006 and 2016. Samples (4027 and 3082 respectively) comprised residents in Barcelona, over 15 years old. Dependent variable: Primary Care (PC) index. Independent variables: age, social class, and birthplace. Analyses included means and percentiles of PC index, and Somers’ D test to compare the distribution of the groups. Results: Comparing 2016 with 2006, the distribution of the PC index remained in women (median of 73.3) and improved in men (from 70 to 73.3). By social class, the pattern of inequality observed in 2006 in men with perceived poor health status disappeared in 2016. Inequalities according to birthplace persisted in women, regardless of perceived health status, but disappeared in men. Conclusions: In the 10 years between which the global economic crisis occurred, the assessment of PC did not worsen, and it did improve for men, but the study points to the need for more focus on people born abroad.

Planificar a partir del aprendizaje colaborativo en la formación inicial de profesores de Geografía

CONICET Digital -

Planificar a partir del aprendizaje colaborativo en la formación inicial de profesores de Geografía; Planning from Collaborative Learning in the Initial Training of Geography Teachers Prieto, Maria Natalia; Volonté, Antonela; Maradona, Guillermina; Lorda, María Amalia El aprendizaje colaborativo es una estrategia activa que fomenta la participación directa de los estudiantes en la búsqueda de alternativas de solución a las contradic- ciones generadas en el proceso de aprendizaje; esta dinámica de trabajo favorece el aprendizaje significativo, las relaciones interpersonales (sociales), la comunicación, el aprendizaje autónomo, el desarrollo de habilidades de investigación y el fomento de valores humanos. La asignatura Didáctica y Práctica de la Geografía se dicta en el último año del profesorado en Geografía (Universidad Nacional del Sur, Argentina) y uno de los puntos centrales del proceso de enseñanza y aprendizaje es la forma- ción en la práctica docente reflexiva y supone una preparación fundamental antes del ingreso al ámbito escolar (práctica docente en la escuela secundaria). En esta instancia de preparación, se emplean diferentes dispositivos de formación, siendo uno de ellos el aprendizaje colaborativo. El objetivo de este trabajo es socializar una experiencia de organización de la enseñanza a partir del aprendizaje colaborativo. En ésta, los estudiantes del profesorado planifican propuestas de aula (en el contexto de una microclase) con un tema geográfico escolar. La experiencia, desde la consi- deración de los testimonios de los estudiantes, resultó innovadora ya que ayudó a fortalecer las habilidades sociales interactivas, la capacidad de autoevaluación, el pensamiento creativo, crítico, analítico y reflexivo. Asimismo, por implicar la gestión compartida de las decisiones didácticas, desde la dimensión cognitiva y socio-afectiva del aprendizaje, resultó una práctica valorada por su aporte al fortalecimiento del aprender a pensar “con el otro”.; Collaborative learning is an active strategy that encourages the direct participation of students in the search for alternative solutions to the contradictions generated in the learning process; This work dynamic favors meaningful learning, interpersonal (social) relationships, communication, autonomous learning, the development of research skills and the promotion of human values. The Didactics and Practice of Geography subject is taught in the last year of teaching in Geography (Universidad Nacional del Sur, Argentina) and one of the central points of the teaching and learning process is training in reflective teaching practice and involves preparation fundamental before entering the school environment (teaching practice in secondary school). In this instance of preparation, different training devices are used, one of them being collaborative learning. The aim of this paper is to socialize an experience of orga- nizing teaching based on collaborative learning. In this, the teaching students plan classroom proposals (in the context of a microclass) with a school geographic theme. The experience, from the consideration of the students’ testimonies, was innovative since it helped strengthen interactive social skills, the capacity for self-assessment, and creative, critical, analytical and reflective thinking. Likewise, because it involves the shared management of didactic decisions, from the cognitive and socio-affective dimension of learning, it was a practice valued for its contribution to strengthening learning to think “with the other.

“Picking up signals” in male genital morphospace and integrating phylogenomics to delimit Neotropical Nylanderia Emery species (Hymenoptera: Formicidae)

CONICET Digital -

“Picking up signals” in male genital morphospace and integrating phylogenomics to delimit Neotropical Nylanderia Emery species (Hymenoptera: Formicidae) Williams, Jason L.; Punnath, Aswaj; Fernández, María Belén; Calcaterra, Luis Alberto; LaPolla, John S.; Lucky, Andrea Genital morphology, a cornerstone in taxonomy that predates Linnaeus’s Systema Naturae, is vital for species delimitation. However, the widely accepted paradigm that genitalia are taxonomically informative lacks robust testing between closely related species, and supporting evidence is often limited to taxonomic literature in which genitalia are assumed a priori to be species-specific. The cosmopolitan ant genus Nylanderia Emery includes 123 described species, with most in the Neotropics still undescribed. Workers are often morphologically cryptic, and males are rare in collections but required for morphological delimitation. Using Ultraconserved Elements (UCEs) from 236 samples, including 53 Neotropical Nylanderia species, we reconstructed a phylogeneticframework to compare the genitalia (gonopods) of males collected alongside workers. We used geometric morphometrics on images of slide-mounted genitalia from 16 species and nano-CT scans of Nylanderia fulva (Mayr) and Nylanderia pubens (Forel) genital capsules and interpreted results considering phylogeny under maximum likelihood and the multispecies coalescent. We found strong morphological and molecular support for 2 distantly related American clades, identifiable by gonopod shape, with significant differences observed among most species. Three previously reported COI clades of N. fulva were not supported as monophyletic, nor were their gonopods significantly different. However, N. pubens was supported as distinct by allphylogenetic and 3DGM results. Our findings emphasize the importance of male genitalia for delimiting species boundaries and revising Neotropical Nylanderia. Given their importance, particularly in morphologically cryptic taxa, we recommend a greater focus on linking male and worker phenotypes, which can be facilitated through comprehensive nest series collection.

Psychometric Features of the Academic Resilience Scale-Short Version (ARS-SV): A Bifactor Exploratory Structural Equation Modeling Study

CONICET Digital -

Psychometric Features of the Academic Resilience Scale-Short Version (ARS-SV): A Bifactor Exploratory Structural Equation Modeling Study Freiberg Hoffmann, Agustín; Romero Medina, Agustin; Vigh, Carlos Donato; Sánchez Rosas, Javier; Fernandez Liporace, Maria Mercedes Academic resilience is the ability to achieve successful results in academic challenges. Since it is an accurate predictor of academic achievement and retention in undergraduates, measuring it is essential.The study aimed at developing a short version of the Academic Resilience Scale (ARS) as well as testing the bifactor model, posed in prior research as an alternative to first-order structures. Items were altered to become linguistically suitable for the target population and examined in terms of content. An exploratory factor analysis (300 undergraduates) retained 12 out of the 30 items ?four per dimension? considering their content and metric features. Confirmatory factor analysis and exploratory structural equation modeling analysis tested and compared different models in 805 undergraduates. As a result, the bifactor ESEM model including three independent dimensions and a global dimension was selected due to its better fit. The short scale enables a valid, reliable and fast assessment of academic resilience in undergraduates.Keywords: Academic resilience, bifactor model, college students, coping skills, psychometric features, short version.
