Body mass and skull measurements in four jaguar populations and observations on their prey base
Authors: Hoogesteijn Rafael , Mondolfi Edgardo
Published: February 2024

Body mass and nine skull measurements of two floodplain (Pantanal and Llanos) and two forest (Amazon and Central America) jaguar (Panthera onca) populations, were analyzed to compare them, relate their morphometric dimensions to preybase and latitude, and examine the relationship with their subspecies status. Analyzing data from males and females separately, jaguar at all sites differed significantly for most variables studied, with the exception of rostral breadth, maxillary teeth row length, and pterygoid fossa breadth for both sexes, and postorbital breadth for females, which were either not or only weakly significant. Individuals from the floodplain populations were consistently larger in almost all parameters than the samples from the forest sites. The difference is independent of the subspecific status. Comparisons among the biomass values of prey taken at each site were also consistently higher for floodplain populations. Jaguar skull size and body mass seem to be more related to biomass of prey taken than to latitudinal location. The differences found in these four populations and the high number of Central American subspecies suggest that a revision of subspecies validity is needed. The reduction in the subspecies number is not only important from a taxonomic point of view but also from an ecological and conservationist one. The increase of our understanding of the phylogenetic heritage and morphological and ecological variation within the species is a priority for conservation.
Freshwater fishes of southern Florida
Authors: Loftus William F. , Kushlan James A.
Published: February 2024

This paper presents the results of the first systematic study of the distribution of fishes in southern Florida's fresh waters. Prior to this study, the known ranges of many fishes at the southern tip of Florida were either poorly understood or in error. The presence of 92 species of fishes in fresh water is documented for extreme southern Florida. The status and distribution of the fishes and the ecological factors that affect them are discussed. Individual species accounts describe each fish's range in southern Florida and provide life history and ecological data. Locations and descriptions of collection sites, an artificial key to juvenile Lepomis species, and a bibliography of southern Florida freshwater fishes are included. This study produced records for several species, such as Carcharhinus leucas, Floridichthys carpio, Fundulus similis, and Agonostomus monticola, that were not well known from southern Florida fresh waters. It also documents freshwater penetration by nine euryhaline species that were not listed from fresh water by Robins et aI. (1980): Adinia xenica, Floridichthys carpio, Fundulus similis, Epinephelus itaiara, Caranx hippos, Oligoplites saurus, Sphyraena barracuda, Gobionellus smaragdus, and Lophogobius cyprinoides. The centrarchids Lepomis gulosus and Lepomis punctatus were collected at their highest recorded salinity, 12.5 0/00. New distributional data have extended the known freshwater ranges of 15 species into extreme southern Florida. Records for freshwater occurrence or persistence by 11 species in southern Florida are regarded as erroneous or dubious. The presence of 12 non-native species is documented, one of which, Cichlasoma citrinellum, is a recent introduction. Distinct distributional patterns exist for several groups of species: Iarge centrarchids occur primarily in canals, cypress sloughs, and headwater rivers; most euryhaline species do not penetrate far inland; the majority of exotic species are most numerous in the canal system; and many small cyprinodontoids are widely distributed in all habitats. The relative abundance of fish species usually varies among habitats. All native primary and secondary freshwater fish species in southern Florida are derived from temperate North American waters. Most are widespread in the southeastern United States. All established non-native species originated in tropical or subtropical regions.
A classification and ordination of the tree community of Tikal National Park, Petén, Guatemala
Authors: Schulze Mark D. , Whitacre David F.
Published: February 2024

We studied tropical forest composition and structure in relation to topographic and edaphic variation. with the goal of understanding the factors that determine species distributions and the degree to which species composition can be predicted by local environmental conditions. We sampled the tree community of Tikal National Park in Petén, Guatemala using 294 sample plots of 0.041 ha each, totaling 12.1 ha, placed systematically along topographic gradients. In addition to recording tree and sapling occurrences, we took data on environmental factors, vegetation structure, and disturbance history. Indirect and direct gradient analyses were performed (using DCA and CCA, respectively) to investigate variation along a predominant topographic/edaphic gradient and along gradients of disturbance and light availability. We used TWINSPAN analysis and ranked sorting of samples by environmental variables to produce a forest type classification practical for field use. Individual species distributions were examined with respect to edaphic conditions, understory light availability, and natural forest disturbance. Though topographic relief is moderate in the area, several edaphic factors varied strongly and predictably, though not monotonically, from hillcrests to low-lying depressions, and exerted a predominant influence on tree community composition. Most tree species distributions were strongly correlated with topography and associated edaphic conditions, and distribution patterns were consistent among widely separated topographic gradients, suggesting that environmental conditions rather than historical events, were largely responsible for these patterns. Many of the less shade-tolerant species also showed positive relationships with natural disturbance history and degree of canopy opening. Treefall gaps have different functional significance for regeneration at different points along the topographic/forest type continuum, due to correlated differences in canopy height canopy evenness, and light penetration. Hence, many species that appear to depend on treefall gaps for colonization and recruitment in upland portions of the continuum, are less confined in their exploitation of lower regions of the gradient, where canopy discontinuities may provide sufficient light for seedling persistence and recruitment. Thus many highly light-demanding species were not associated with treefall gaps, and appeared capable of colonizing relatively open lowland forests. Distribution patterns and disturbance/light responses are discussed for individual species, which are provisionally placed into ecological guilds based on apparent tolerances for light levels and edaphic and other environmental factors. In Tikal, much of the natural variation in forest composition and structure can be related to topography and edaphic conditions.

Analysis of multimodal passenger terminal design and its effects on transfer penalty
Authors: Rusanen Iina , Wiest Florian
Published: February 2024

With public transit systems becoming more and more sophisticated, the likelihood of passengers having to transfer between modes or lines increases. Transferring burdens, the passenger with added mental and physical effort, referred to as transfer penalty, which has a negative effect on the travel experience. The physical design of multimodal transfer terminals, such as train stations, can have a significant effect on transfer penalties but has received relatively little attention in practice. The aim of this review essay is to create an understanding of the ways in which the physical design of terminals can influence the transfer penalties experienced by passengers. Our findings show that terminal design can influence transfer penalties through actual and perceived walking and waiting times at transfer as well as the pure transfer penalty. We identified distinct categories of design elements and of other parts of the transit systems that urban designers can employ in influencing these aspects.

Analysis of the Formation of Government Regulations as Separation of Powers in Indonesia
Authors: Halim Fajri
Published: February 2024

Indonesia is a constitutional state where government administration is based on statutory regulations hierarchically proposed by the law as mandated by the 1945 Constitution. The authority to implement laws is translated into government and other laws and regulations. The order of laws and regulations is used as a "rule" when a government activity is to be carried out. However, in practice, there are still mechanisms for forming PPs that are inconsistent with the orders of the law. This study aims to determine the basis and mechanism for forming PP as an executive authority and the legal implications of not issuing PP by the executive. The type of research is normative juridical with a literature study approach. The analysis shows that the process of forming laws can be studied from two perspectives, namely normative juridical and sociological perspectives. The material content of laws in Indonesia is complex to determine from the power-sharing system. However, it can be determined by looking at the system for forming statutory regulations, where it has been stated that the formation of statutory regulations must be based on hierarchical law. Suppose the executive does not issue a PP as mandated by the law. In that case, it will result in not achieving the ideals of the general norms contained in the law, and harmonisation of law implementation will not be realised. Even though it is a country based on law, no government administration in Indonesia is not based on statutory regulations as its legal basis
The Fundamental Position Of Lex Posterior Derogat Legi Priori in the Conflict of Norms Against the Rights of Holders of The Right to Justice
Authors: Naiborhu Mesa Indra , Wagiman Wagiman
Published: February 2024

The principle as a fundamental rule is the background of the legal system, starting from the formulation and formation of laws and regulations to the enforcement of the regulations in question.  Legal principles are a very important element in the formation of laws and regulations.  Violation of norms shows a tendency to violate principles, and the elimination of norms will impact the tendency to eliminate principles.  The methods used are the conceptual approach and the statute approach.  The data sources used are secondary data that researchers can obtain from literature studies in the form of books, records, newspapers, journals, and other documents that can be used in this study.  Secondary data consists of primary legal materials, secondary legal materials, and tertiary legal materials. Research results: (1) The position of the lex posterior derogat legi priori principle cannot be placed as a basis for overcoming the conflict of norms between UUK-PKPU and UUHT. (2) Resolution of norm conflicts between UUK-PKPU and UUHT can be done through a harmonisation approach of the two laws through the legislative process in the DPR. The bankruptcy process shows a conflict arising between UUK-PKPU and UUHT because the holder of the dependent right should still be authorised to exercise all his rights even though the grantor of the dependent right is declared bankrupt by article 21 of the Law. In contrast, Article 56 paragraph (1) suspends the rights of creditors of the holder of the 'dependent right'. To overcome the conflict of norms, it should be understood that the principle of lex posterior derogat legi priori means that the new norms/rules of law perfect the enforceability of the old norms/rules of law in the same legal regime

Authors: Indra Rezhi Dika , Rachman Ade Syaiful , Wafiyuddin Wafiyuddin , Soedjono Eddy Setiadi
Published: February 2024

PDAM Surya Sembada Surabaya’s energy cost in 2021 amounted to Rp 147.654.439.569, with an energy cost ratio of 24.37%, and the electricity cost of production unit accounted for 76% of the total energy consumption of PDAM. The relatively flat topography does not allow gravity-based systems for water supply. Aging equipment has decreased overall pump efficiency (ηpt) and increased energy consumption, particularly in Ngagel I WTP, built in 1922, necessitating an energy audit. Energy audit includes measuring pump flow rate and pressure, power, voltage, current, power factor, pump and motor pump rotation and temperature. Analysis shows that raw water pumps U2, U3, U5, and S1 and distribution pumps U1, U3, and T4 are still in good condition. However, raw water pump U6 and distribution pumps U6, S1, and S2 require reconditioning and impeller adjustment due to declining efficiency. Furthermore, PDAM must inspect the distribution pump T1 with the lowest efficiency value (49.77%) to determine the appropriate repairs. The research results are action recommendations expected to serve as input and considerations for PDAM in their efforts to improve energy efficiency.

Published: February 2024

Reinforced concrete is the most commonly used construction material in building construction in the 21st century. In its production, supportive instruments are needed to enhance both quality and economic aspects. Formwork, or shuttering, is a crucial factor in the casting and hardening of concrete. The subject of this research is wooden formwork and its alternatives, analyzed in terms of cost, quality, time, and convenience using the Value Engineering Job Plan analysis. In terms of cost, there is a cost savings of 8.88% for DUO polymer formwork compared to the conventional plywood method. The resulting surface quality of the concrete of this method has a average roughness of 3.492. The total duration of the work is 16.54791 days. The total value index obtained for the use of DUO polymer formwork is 98.99, for the plywood film formwork is 48.17, and for conventional plywood formwork is 0.00. Thus, in terms of value, the DUO polymer plastic formwork can be recommended as the best formwork method for multi-story building construction. Considering the advantages and disadvantages of this method, along with the benefits obtained, it would be even more beneficial on a larger construction scale.

Published: February 2024

The comfort of the hospital lobby is very influential in ensuring that health services in the hospital run optimally. Comfortable lobby conditions can reduce anxiety when patients have to wait their turn to be examined or wait for medicine from the pharmacy. Apart from that, the comfortable lobby creates optimism for recovery for patients and their families, including medical personnel who work at the hospital. This research aims to measure how significant the influence of room comfort, thermal comfort, visual comfort and audio comfort is on the comfort of the lobby room seen from the architectural design of the room. The benefits of the research enrich the results of previous research that building comfort variables influence the dynamics of perceptions of physical comfort. The research uses quantitative methods and data collection techniques are carried out by direct observation and questionnaires that are distributed to hospital visitors, managers, medical teams and patients. Data were analyzed using descriptive quantitative methods to assess the comfort level of the hospital lobby. From the results of this research, it is concluded that the aspect of freedom of movement has the greatest influence on the comfort level of the lobby space, so it must be taken into consideration when designing a hospital lobby that is comfortable for visitors.

Authors: Kim Taegyoung , Choi Namki , Kim Seonmi
Published: February 2024

This study aimed to analyze the prevalence and severity of infraoccluded primary molars (IPM) and their correlation with the agenesis of permanent successors (APS). A total of 4,011 panoramic radiographs from children aged 4 to 11 years who had all 8 primary molars were examined. The prevalence of APS was analyzed based on the severity and tooth type of IPM. The prevalence of IPM was 13.0%, and there was no difference between genders. The majority of the children had two IPMs each. In all tooth types, mild infraocclusion was the most prevalent, whereas severe infraocclusion was the least frequent. Among the types of primary molars, the lower primary first molar (62.3%) was the most affected, followed by the lower primary second molar (27.7%), the upper primary second molar (5.8%), and the upper primary first molar (4.2%). Infraocclusion was 11.2 times more prevalent in the mandible than in the maxilla, with no significant difference between the left and right sides. The correlation between IPM and APS was also investigated. Among the subjects, 177 had one or more agenesis of premolars, of whom 54 (30.5%) had IPM. Additionally, among the 521 individuals with IPM, 54 individuals exhibited APS (10.4%). This study identified a noteworthy prevalence of infraocclusion, with notable variations among molar types. The LPFM was particularly affected. The majority of cases were classified as mild in severity. Furthermore, a compelling association between IPM and APS was established. Understanding this connection may enhance treatment strategies for infraoccluded teeth and tooth agenesis.

Authors: Guler Ayhan , Okmen Gulten
Published: February 2024

Foodborne pathogens pose a significant hazard to food safety. Most cases of foodborne illnesses are caused by bacterial pathogens that have infiltrated the food chain at some point, from farm to kitchen. According to the World Health Organization (WHO), approximately one-third of individuals in developed countries are affected by foodborne pathogens each year. Although there are studies on Hypericum perforatum L. in the literature, research in Turkey remains limited. Therefore, the aim is to contribute to the literature by studying H. perforatum samples from the Yaraş region of Muğla province in Turkey. This study specifically aims to investigate the antimicrobial activities against foodborne pathogens and the antioxidant activity of H. perforatum in Muğla. The in vitro antimicrobial activities of flower components from plants grown in Mugla were evaluated using the disc diffusion method and broth dilution test. Additionally, the extracts underwent ABTS (2,2'-azinobis-(3-ethyl benzothiazoline-6-sulfonic acid)) free-radical testing to evaluate their antioxidant activity. The extract exhibited a maximum inhibition zone of 16 mm against Staphylococcus aureus and Listeria monocytogenes. Notably, S. aureus and L. monocytogenes demonstrated the lowest sensitivity to H. perforatum methanol extract (1625 µg/mL). The methanol extract displayed moderate antioxidant activity, with a 53% ABTS radical scavenging capacity. Consequently, the extracts of H. perforatum exhibited both antimicrobial and antioxidant potential.

Published: February 2024

Background: Hypo chromic microcytic anemia happens to be the commonest form of anemia in Pakistan. Iron deficiency anemia (IDA) and Beta Thalassemia Trait (BTT) are its most common causes. Both are having similar clinical and laboratory findings. It is necessary to establish relevant cost-effective screening methods based on blood complete picture (CP) to predict BTT in order to reduce burden of Beta Thalassemia Major in Pakistani population.
Methods: A cross sectional study was conducted from 2019 to 2021. 10,739 BTT or IDA suspected subjects were recruited. Blood CP was done for each patient to analyze different red cell parameters like total red blood cell count (TRBC), hemoglobin (Hb), mean cell volume (MCV), mean cell hemoglobin(MCH), mean cell hemoglobin concentration(MCHC) and red cell distribution width(RDW). For serum ferritin level, serum was collected after centrifugation and analyzed by using Abbott Alinity chemistry analyzer.
Results: 1044 individuals had BTT and 270 were diagnosed as having IDA. Their RBC indices were analyzed using 25 formulae to differentiate between both conditions. Matos and Carvalho index and Pornprasert discriminative index appeared to be the most reliable indices with sensitivity, specificity, positive and negative predictive values, more than 98%.
Conclusion: By utilizing Matos and Carvalho index and Pornprasert index, we can cost effectively screen huge population for BTT

Nigeria Exchange Rate: Towards Nigeria’s Exchange Rate Convergence to Pre-Buhari Years
Authors:   Garden City Premier Business School, Port Harcourt-Nigeria, Oyebanji-Umaigba Adejoke , Opuala - Charles Silva
Published: February 2024

This paper explores the trajectory of Nigeria’s exchange rate policies, examining their evolution and impacts on the Naira’s value. From the fixed exchange rate era to the recent Unified Exchange Rate System, the study dissects historical shifts and their repercussions on the economy. The Nigerian exchange rate regime has gone through different eras from 1970s till date. Various factors necessitated the need for exchange rate policy changes; however, the result of the policy changes have over the years been eroded and its value has been on a continuous decline. Key factors contributing to the Naira’s persistent decline, including import dependency, reduced oil production, and inflation, are scrutinized. The role of currency speculation and the impact of government policies are also analyzed. The paper recommends short-term measures, such as adjusting exchange rate policies and lifting import restrictions, and long-term solutions, including infrastructure development and sectoral growth. The government should monitor the behavior of the exchange rate market closely and ensure interventions using both fiscal and monetary policies are implemented to fortify Nigeria’s economic resilience and counter the continuous depreciation of the Naira. Keywords: Exchange Rate, Exchange rate regime, globalization, fiscal policy.
Pediatric and adult osteoporosis: a contrasting mirror
Authors: Ferjani Hanene Lassoued , Cherif Ines , Nessib Dorra Ben , Kaffel Dhia , Maatallah Kaouther , Hamdi Wafa
Published: February 2024

Pediatric osteoporosis (PO) is a condition that is currently gaining recognition. Due to the lack of official definitions over the past few decades, the exact incidence of PO is unknown. The research does not provide a specific prevalence of PO in different world regions. However, this is expected to change with the latest 2019 guidelines proposed by the International Society of Clinical Densitometry. Although adult osteoporosis (AO) has been postulated a pediatric disease because its manifestation in adulthood is a result of the bone mass acquired during childhood, differences between PO and AO should be acknowledged. AO is defined as low bone density; however, PO is diagnosed based on existing evidence of bone fragility (vertebral fractures, pathological fractures). This is particularly relevant because unlike in adults, evidence is lacking regarding the association between low bone density and fracture risk in children. The enhanced capacity of pediatric bone for reshaping and remodeling after fracture is another difference between the two entities. This contrast has therapeutic implications because medication-free bone reconstitution is possible under certain conditions; thus, background therapy is not always recommended. In this narrative review, differences between PO and AO in definition, assessment, and medical approach were investigated.

Purpose: We prospectively evaluated the association of the insulin resistance of third-trimester Nigerian pregnant women with their newborn infants' insulin resistance and birth size. Pregnancy-associated insulin resistance (IR), often assessed with homeostatic model assessment of IR (HOMA-IR), is associated, especially among women with gestational diabetes (GDM), with abnormal neonatal birth size and body composition, predisposing the baby to metabolic disorders like diabetes and obesity. The associations of maternal IR with neonatal IR, birth size and body composition are less studied in nondiabetic pregnant women, especially in sub-Saharan settings like Nigeria.Methods: We originally recruited 401 third trimester, nondiabetic pregnant women to a prospective cohort study, followed up until birth. Blood samples of mothers and babies were obtained, respectively, at recruitment and within 24 hours postbirth for fasting serum glucose (FSG) and insulin (FSI) assays, and HOMA-IR was calculated as [(FSI × FSG)/22.5)].Results: Complete data for 150 mother-baby dyads was analysed: the mothers, with a mean (standard deviation [SD]) age of 31.6 (4.5) years, had live births at a mean (SD) gestational age of 39.2 weeks. The proportions of infants with wasting, stunting, impaired fetal growth (either wasting or stunted), small-for-gestation-age, large-for-gestational-age, low birthweight, and macrosomia were 4.2% (95% confidence interval, 1.1–10.3), 19.7% (12.9–28.0), 23.1% (15.8–31.8), 10.1% (5.3–17.0), 12.6% (7.2–19.9), 0.8% (0.02–4.5), and 5.0% (1.8–10.5), respectively. Maternal HOMA-IR was not associated with neonatal HOMA-IR (p=0.837), birth weight (p=0.416) or body composition measured with weight-length ratio (p=0.524), but birth weight was independently predicted by maternal weight (p=0.006), body mass index (p=0.001), and parity (p=0.012).Conclusion: In this nondiabetic/non-GDM cohort, maternal HOMA-IR was not associated with neonatal IR, body size or body composition. Larger studies are required to confirm these findings, with addi-tional inclusion of mothers with hyperglycaemia for comparison.

El presente trabajo aborda, desde lo conceptual a lo aplicado, las oportunidades y desafíos que se presentan con la inclusión de la Ciencia, la Tecnología y la Innovación (CTI) en las políticas de los gobiernos subnacionales. Se analiza el caso de las políticas implementadas durante el periodo 2016-2019 en el Ministerio de Ciencia y Tecnología de la provincia de Córdoba (MinCyT), Argentina. Se describe un breve recorrido de la trayectoria de este organismo, para luego presentar un diagnóstico de situación preexistente al periodo en análisis y gran parte del Plan Estratégico de Gestión (PEG) con sus principales alcances. En ese recorrido, emergen algunos de los conceptos que aportaron a la elaboración y ejecución de la gestión en CTI, se detalla también cuáles fueron las principales carencias y barreras que la implementación del PEG encontró y se esbozan algunas hipótesis sobre qué impacto tuvieron las mismas. Si bien este análisis de caso se concentra en una experiencia situada en una provincia argentina, de su revisión emergen aprendizajes y estrategias que pueden considerarse como contribuciones para promover la adopción y gestión de políticas públicas en CTI a nivel subnacional.
Educación Superior, CTI y desigualdad: límites y contradicciones sistémicas en tiempos de COVID-19

Published: February 2024

Durante por lo menos los últimos treinta años se proyectó la promesa de que el progreso científico y tecnológico permitiría garantizar el desarrollo económico y el bienestar social, y realizar los valores de la razón y el bienestar para todas y todos. En contra de los grandes anhelos y logros previstos por el movimiento globalizador en el mundo, hoy vivimos una reelaboración de la exclusión que se intensificó con la pandemia causada por la enfermedad COVID-19, y que ha derivado en la exacerbación de las desigualdades que proyectan al mundo como un espacio fragmentado en el que unos cuantos se benefician de la concentración de la riqueza que lleva a amplios segmentos de la población del mundo a vivir en los márgenes de la llamada “civilización”. Es el caso del acceso a la Educación Superior en México, pero también de su permanencia y relación con la desigualdad. Particularmente, interesa revalorar las relaciones entre Educación Superior -específicamente la formación profesional en las universidades públicas- la Ciencia, la Tecnología y la Innovación (CTI) y su participación en este proceso, a la luz de perspectivas teóricas que reconocen en el sistema capitalista el principal límite a una transformación real en la estructura socioeconómica actual, más aún en tiempos de COVID-19. Desde una visión normativa que defiende el valor social del conocimiento, creemos que existe un amplio marco de oportunidades para que haya transversalidad en la política de Educación Superior y la de CTI para generar condiciones que combatan la estructura de la desigualdad.
Internacionalización y competencias interculutrales en la Educación Superior
Authors: Zilberberg Oviedo Lourdes Evangelina
Published: February 2024

Este artículo presenta los resultados de un estudio realizado en el ámbito brasilero de la Educación Superior que buscó analizar las contribuciones de la internacionalización al desarrollo de competencias interculturales en los estudiantes de las instituciones miembros de FAUBAI- Associação Brasileira de Educação Internacional. La metodología utilizada fue el Estudio Explicativo Secuencial de Método Mixto con predominancia cualitativa, lo que permitió combinar cuestionarios iniciales con entrevistas semiestructuradas. En ambas instancias se trabajó con gestores de las oficinas de relaciones internacionales y con estudiantes.  El aporte práctico más relevante de este trabajo es el abordaje inédito del estudio de las competencias interculturales, analizadas como resultado del proceso de internacionalización, en tanto que los principales aportes a la teoría están constituidos por las primeras definiciones locales de competencia intercultural y de interculturalidad, las que resultaron de una construcción colectiva a partir de los comentarios de los sujetos de la investigación
II Jornadas regionales de investigación en Educación Superior

Published: February 2024

Las “Jornadas de Investigación en Educación Superior” (JIES) constituyen el evento más importante en la temática que se desarrolla en Uruguay ya que congrega a instituciones públicas y privadas de Educación Superior y de educación terciaria. Tienen como objetivos: promover la acumulación de conocimiento y el fortalecimiento del campo de la Educación Superior en las instituciones públicas; estimular el intercambio y la confluencia de miradas, temáticas, producciones con perspectiva regional; generar un espacio de reflexión crítica y de debate sobre asuntos prioritarios de la agenda educativa que requieren nuevas y creativas formas de resolución. Desde la edición anterior, al mismo tiempo se convoca un encuentro regional. Así, con la convocatoria de la Universidad de la República (Udelar), el Consejo de Formación en Educación (Administración Nacional de Educación Pública), y el Núcleo de Estudios e Investigaciones en Educación Superior del Mercosur (NEIES) -integrado por representantes de Argentina, Brasil, Paraguay, Uruguay, Chile y Venezuela-, se llamó a la presentación de investigaciones culminadas o con un importante grado de avance que no hayan sido publicadas ni expuestas en eventos nacionales, inscriptas en 13 ejes temáticos (Educación Superior, política y sociedad; Transformación de la enseñanza; Posgrados y Educación Permanente; Ciencia, Tecnología y Sociedad; Educación Superior y trabajo; Sujetos contemporáneos, aprendizaje y comunicación; Articulación de funciones universitarias; Profesión académica y desarrollo profesional docente; Articulación y cooperación interinstitucional de la educación; Inclusión, diversidad cultural, derechos humanos y género; Evaluación y acreditación universitaria; Internacionalización, movilidad y reconocimiento de formaciones y La Educación Superior en contexto de pandemia).
