TENDENTIAL MODELING OF DEFORESTATION IN CAATINGA BIOME IN PIAUÍ STATE
Authors: Dos Santos Raianara Andrade , Juvanhol Ronie Silva , Aguiar Adriano Saraiva
Published: August 2022

The work aims to simulate the dynamics of deforestation in the area that covers the caatinga biome in the state of Piauí for the next five decades. In the simulation, the program Dinamica EGO was used. Were acquired deforestation data for 2002 and 2008 and spatial data of the explanatory variables of deforestation in the area. Five steps were performed: calculating the transition matrices, determining the weights of evidence, adjusting, validating and projecting the model in the trend scenario. Transition rates for total and annual deforestation resulted in 4.6% and 0.8%, respectively. The weights of evidence revealed that distances up to 600 m from deforested areas influence in the process of transition to deforestation. The variables with the highest weights were altitude, up to 100 meters; areas closer to urban patch and sustainable use units, in addition to land use and cover classes: urban influence, agriculture, livestock. With the simulated images it was observed a reduction of the forest remnants of caatinga area in the state, from 69% in 2008 to 43% in 2070. These results serve as a warning to the public authorities and the population. The proposed methodology can be applied to other Brazilian biomes with different approaches.

Published: August 2022

O rápido crescimento da população urbana, no Brasil, trouxe impactos significativos, gerando complexos problemas sociais e ambientais. Assim, o presente trabalho tem por objetivo propor novas áreas urbanas, no Distrito Federal, que tenham potencial sustentável, ou seja, espaços que possam ser apropriados de forma a garantir mínimos impactos ao sistema ambiental de forma a não comprometer a oferta de serviços ecossistêmicos vitais. Como método, foram utilizadas técnicas de análise multicritério e Análise Hierárquica Ponderada, combinadas a ferramentas de geoprocessamento. Um mapa de restrição foi aplicado às áreas destinadas à preservação ambiental e, além disso, algumas áreas, estabelecidas por instrumentos legais, foram analisadas. Os espaços com potencial urbano foram bem distribuídos em todo o território do DF, especialmente, a leste do mapa. Ao mesmo tempo foi possível identificar áreas com maior necessidade de preservação quanto à manutenção ecológica, como a região noroeste do DF. A designação de espaços urbanos, através do método apresentado, é importante para garantir um menor impacto ambiental, visto que a escolha dos critérios, a sua classificação e a sua ponderação foram trazidas como parte integrante de suporte aos sistemas ecológicos fundamentais, o que visa assegurar o funcionamento sustentável do território.

A ausência de planejamento durante a expansão acelerada das cidades brasileiras foi propícia para a instauração de problemas urbanos, dentre os quais está a irregularidade fundiária, que acomete o país, com predominância nas localidades habitadas pelas camadas populares. Neste sentido, o objetivo deste trabalho é discutir os procedimentos de Regularização Fundiária de Interesse Social executados no período de 2018 a 2020, no Conjunto Habitacional Eldorado, localizado no município de Natal/RN. Para tanto, fez-se necessário acompanhar as atividades desempenhadas pelo Projeto Regularização Fundiária Urbana das Unidades Habitacionais dos Diversos Municípios que compõem o Estado do Rio Grande do Norte (REURB-S) inerentes à Regularização desta área, desde a sua concepção até a fase de entrega de documentos ao Cartório de Registro de Imóveis. Verificou-se que o Conjunto Habitacional foi instalado em 1991, é ocupado predominantemente pela população de baixa renda, e até o ano de 2018 ainda não tinha seus lotes registrados em nome dos proprietários moradores. A execução das etapas da regularização fundiária permitiu pensar o Conjunto para a promoção da qualidade de vida de sua população, com a sugestão de projetos de melhoria e adequação; contribuir para o planejamento da cidade; e avançar na sua inclusão na cidade formal.

Published: August 2022

Pastures play a critical role in the global ecological system, covering approximately 20% of the global terrestrial surface. This paper aims to review the progress of research on pasture degradation in different countries. The main research methods for this study include bibliometric analysis, social network analysis and viewing analysis - covering the performance of publications, characteristics of related journals, countries, institutions and authors. The Impact Factor, the H-index and the number of citations are used to investigate the strength of active institutions, authors and scientific periodicals in the field of pasture degradation. Therefore, we intend to outline the research trends already made and point out to future studies. We found 1027 articles published between 1956 and 2018, but none of them has reviewed science in a systematically way. The majority of authors are from China, United States and Germany. These lines of research aim to show the dynamics of pasture in response to the climate, the changes in human activity, the estimates of degraded or healthy areas and the evaluation of public policy interventions. In terms of publication productivity analysis, we highlight the Journal of Arid Environments, the author Richard J. Dean and the institution Chinese Academy of Sciences.

Com a intensificação das atividades antrópicas em decorrência da demanda global por insumos oriundos da produção agrícola, os recursos naturais vêm sofrendo sérios impactos refletindo, sobretudo, na degradação da cobertura vegetal primária. Assim, muitos estudos têm buscado avaliar esses impactos nos atributos físicos do solo. Portanto, o objetivo deste trabalho foi avaliar a influência dos segmentos de vertente nos atributos físicos do solo em duas topossequências em áreas de brejo de altitude, Areia, PB. Foram selecionadas duas topossequências sob fragmento florestal e pastagem, estabelecendo um caminhamento a partir do “espigão” no sentido do caimento mais suave do relevo, esses segmentos foram determinados com base na “quebra” de declive do terreno. Foram abertas minitrincheiras na camada de 0,00-0,20 m, coletadas amostras nos diferentes segmentos de vertentes: topo, meia encosta e sopé de deposição. Em seguida, foram coletados 30 anéis volumétricos de 5,0 cm de altura e 5,0 cm de diâmetro interno e 30 amostras preservadas em forma de torrão. Foram realizadas análises texturais, densidade do solo, macro, micro, porosidade total, agregados, condutividade hidráulica e umidade gravimétrica. Foram realizadas análises de estatística descritiva e análise de variância sendo comparado pelo teste de Tukey ao nível de 5% de probabilidade. Houve predominância dos teores da fração areia em todos os segmentos de vertente estudados, com leve incremento dos teores de argila na área de pastagem em relação a de floresta, fato provavelmente associado ao material de origem gnaisse e não as pedoformas. Os atributos físicos-hídricos apresentaram resultados semelhantes com poucas exceções.

A agregação do solo é influenciada diretamente pelo manejo, sendo que a matéria orgânica é um dos principais responsáveis por essa agregação. Este estudo objetivou avaliar os agregados dos solos sob distintas intensidades de uso em Pernambuco e Paraíba. Os solos foram coletados em dez locais nos Estados da PB e PE, em áreas selecionadas sob vegetação de caatinga (caatinga preservada e caatinga raleada) contígua a área sob agricultura de subsistência (cultivada preservada e cultivada degradada). Os solos foram amostrados na camada de 0,0-7,5 cm. Em seguida à separação dos agregados secos e úmidos e determinação do diâmetro médio ponderado de agregados úmidos e de agregados secos. O índice de estabilidade foi calculado pela relação diâmetro médio ponderado de agregados úmidos e secos. Com relação aos resultados, a intensidade do uso do solo influenciou nas proporções dos agregados dispersados via úmida em todas as classes de tamanho, exceto a classe > 2 mm. Verificou-se que a proporção de agregados na fração >2 mm foi a que mais diminuiu entre as dispersões seca e úmida, sendo que a fração 1-0,5 mm ficou inalterada em relação aos sistemas de dispersão. O diâmetro médio ponderado seco não foi afetado pela intensidade do uso do solo, porém os valores de diâmetro médio ponderado úmido das áreas de caatinga preservada e cultivada foram superiores aos de caatinga raleada e cultivada degradada. Os sistemas de uso caatinga preservada e a cultivada preservada apresentaram maior estabilidade de agregados que caatinga raleada e cultivada degradada.

The intensification of agriculture has increased the traffic of heavy machines, which can cause soil compaction, becoming a limiting factor for plant growth and development. The aim of this work was to evaluate the effects of machine traffic on soil physical attributes, root growth and dry mass production of legumes and grasses cultivated as cover. The experiment was carried in Rolim de Moura (RO). The experimental design was randomized blocks, in a split-plot scheme, with three replications. The treatments in the plots consisted of four induced soil compaction states: 0, 1, 4, 7 passes of an agricultural tractor, and in the subplots four cover crops species: Crotalaria, Stylosanthes, Millet and Palisadegrass. After two days of intense rainfall, compaction was carried out by passing the wheelsets of a New Holland-TL85E agricultural tractor, with 88hp of power, 4x2 TDA, standard tires 7.5x16 and 18.4x34, with blowing pressure of 110 kPa and 124 kPa, with a total mass of 3.16 Mg. Density, microporosity, macroporosity and total porosity were evaluated, surface area, root length and diameter and dry mass were also evaluated. During the period of full flowering of each crop, trenches were opened in each subplot for root evaluation and deformed soil and shoot dry mass samples were collected for evaluation. Significant discrepancies were observed for the physical attributes evaluated, surface area, length and root diameter of grasses in relation to legumes. After a tractor pass, there is an increase in soil density, and reductions in macroporosity and total porosity.

We show that if an eventually positive, non-arithmetic, locally Hölder continuous potential for a topologically mixing
countable Markov shift with (BIP) has an entropy gap at infinity,
then one may apply the renewal theorem of Kesseböhmer and Kombrink to obtain counting and equidistribution
results. We apply these general results to obtain counting and equidistribution results for cusped Hitchin
representations, and more generally for cusped Anosov representations of geometrically finite Fuchsian groups.
Pursuit of “endpoint diagnoses” as a cognitive forcing strategy to avoid premature diagnostic closure
Authors: Kaplan Holland M. , Birnbaum Jacqueline F. , Kulkarni Prathit A.
Published: August 2022

Premature closure is often described as a significant contributor to diagnostic error. Therefore, developing strategies to mitigate premature closure could reduce diagnostic errors and improve patient care. Here we propose the novel concept of pursuit of an “endpoint diagnosis” as a cognitive forcing strategy (CFS) for avoiding premature diagnostic closure. We define an “endpoint diagnosis” as an underlying causative explanation for a patient’s signs, symptoms, and laboratory and radiographic data that exhausts additional relevant diagnostic evaluation. We have observed four contexts in which the error of not pursuing an endpoint diagnosis most often occurs: (1) diagnoses that appear to result in the same treatment regardless of etiology, (2) cases that are particularly complex, (3) clinical scenarios that are vulnerable to systems errors, and (4) situations in which patients’ problems are attributed to uncontrolled underlying risk factors or an exacerbation of a known condition. Additionally, we address why we believe endpoint diagnoses are not universally pursued, delineate when this approach might be particularly useful, attempt to reconcile the potential conflict between accepting diagnostic ambiguity in certain instances and pursuing endpoint diagnoses, and outline possible concerns that might arise with using this CFS, including the possibility of lengthy evaluations resulting in overdiagnosis and overtreatment. Our overarching goal is for this CFS to help clinicians in their daily clinical practice as they seek to optimize their diagnostic skill and patient care.

Published: August 2022

Li-ion secondary battery is highly recommended as a power source to highly advanced battery electric vehicles. Among various types, the lithium nickel cobalt aluminum oxide (NCA) battery is considered suitable for high energy and power application. In this study, the NCA cathode material LiNi0.89Co0.08Al0.03O2 was produced via the oxalate co-precipitation technique to reduce the overall production cost and process complexity. Oxalic acid and a small amount of sodium hydroxide were used as the precipitant and pH regulator, respectively. Homogenous and loose metal oxalate precipitate formation was confirmed by X-ray diffraction (XRD), scanning electron microscopy, and Fourier-transform infrared spectroscopy analysis. XRD patterns of the as-obtained micron-sized NCA showed a well-layered hexagonal structure. The electrochemical properties of the cathode in the full cell were thoroughly examined. The specific discharge capacity of the as-obtained NCA in NCA/LiPF6/graphite at a current rate of 20 mA/g was 142 mAh/g. The as-prepared NCA sample had capacity retention of 80% after being charged and discharged at 0.1 A/g for 101 cycles. Scaling up of NCA production process to 2 kg per batch was conducted and evaluation of NCA product quality was performed by material characterization. Based on the overall results and considering the overall process, such an approach is expected to be developed and improved for future large-scale production purposes.
Identification of high-temperature targets in remote sensing based on correspondence analysis
Authors: Yu Yifan , Du Huishi , Fan Juan , Liu Jiafu , Liu Jiping , Pan Jun
Published: August 2022

High temperature targets (temperature above 500 K), are the special on the surface of the earth such as forest fire, prairie fire, oil well torches, heap coking, volcanic eruptions, significantly different from those of normal surfaces at lower temperatures. Identification of high-temperature targets plays an important role in environmental monitoring, disaster warning, and resource investigation. In remote sensing data, high-temperature target pixels and bands are studied. And they are deemed samples and variables, respectively, in multivariate analysis. And classification of samples for identification of high-temperature targets is necessary. To classify samples, feature analysis of spectrum needs to be done first. In feature analysis of spectrum, feature bands that can be used to distinguish samples need to be selected. Correspondence analysis is the method that can project samples and variables into the same factor space in the meantime. It can realize the classification of samples and variables synchronously, and the results can be interpreted by each other. First, the correspondence analysis is conducted on Landsat8/OLI remote sensing imagery to build the relationship between samples and variables. After that the correspondence relationship between identification results of high-temperature targets and feature bands can be built in the physical theory of remote sensing and factors which have indicative significance on fire are confirmed. Finally, the single band threshold method is adopted to realize high temperature target recognition by using factor scores. In the field confirmation, results suggest that the precision of identification of high-temperature targets reaches 92%. And we also get a consistent result with SWIR temperature inversion.

Published: August 2022

Rainfall and surface water infiltration will affect the safety of loess slope. Ecological slope protection can protect and reinforce the surface layer of the slope by using the anchoring effect of plant root. In this study, the prevention and control technology of grass planting on loess slope in the solidified soil was studied. Heavy metal contents in the soil after addition of the stabilizer met the farmland standard at the end of the growth period. A comparison of the biomass data of different groups of solidified soil showed that the biological characteristics of plants had the best response at the mixture ratio of solidified soil of 0.86%. The shear strength of the root–soil composite increased by about 60% compared with that of plain soil at the mixture ratio of 0.86% stabilizer, and the permeability coefficient can be reduced by two orders of magnitude. Through the field engineering application, the ecological restoration test using loess soil solidified by consolid system with grass planting met the engineering requirements, with clear soil and water conservation benefits. Therefore, planting grass in solidified soil can effectively reduce the erosion of soil and improve the stability of the shallow slope.

Authors: Alderremy Aisha Abdullah , Khan Hassan , Khan Qasim , Kumam Poom , Aly Shaban , Ahmad Said , Sitthithakerngkiet Kanokwan
Published: August 2022

In this article, the solutions of higher nonlinear partial differential equations (PDEs) with the Caputo operator are presented. The fractional PDEs are modern tools to model various phenomena more accurately. The residual power series method (RPSM) is used for the solution analysis of fractional partial differential equations (FPDEs), which has direct implementation for the solutions of fractional partial differential equations. In this work, the solutions to a few nonlinear FPDEs are handled by the proposed technique. The general and particular schemes of RPSM are constructed and implemented successfully. The fractional solutions of PDEs have provided many useful dynamics of the targeted problems. The RPSM results for both integer and fractional-order FPDEs are further explained and elaborated by using graphs and tables. It is observed that the higher accuracy of RPSM is achieved with fewer calculations. Graphs and tables for fractional-order solutions are presented, which confirm the convergence phenomena of fractional solutions toward integer order solutions of each problem. The suggested method can be extended to the solutions of other nonlinear fractional partial differential equations.
Getting China into the game: Bilateral labor agreements in the system of global labor rights
Authors: Hyde Alan
Published: August 2022

Bilateral trade agreements are the preferred mode of transnational regulation for the People’s Republic of China. China has made promises on labor rights in draft bilateral agreements that it has not previously made in any other venue. The future of transnational labor regulation requires Chinese participation. Bilateral agreements should therefore become a normal part of transnational labor law. Model labor rights provisions for bilateral agreements should be promulgated. Consultative and informal enforcement will be necessary.
Entrapment processes in the emigration regime: The presence of migration bans and the absence of bilateral labor agreements in domestic work in Nepal
Authors: Bhagat Ayushman
Published: August 2022

This Article offers an integrated analysis of the combined effect of the presence of migration bans and the absence of BLAs in domestic work in the emigration regime of Nepal. It identifies, acknowledges, critiques, and contributes to the critical literature highlighting entrapment processes in labor relations and immigration regimes by demonstrating the presence of such in the emigration regime. Drawing on the empirical findings of a participatory action research (PAR) project conducted in Nepal, the Article demonstrates how restrictive emigration policies and practices entail entrapment processes constitutive of the existing historical, cultural, gendered, racialized, and classed constraints impacting the lives of Nepalese citizens. The Article contributes to the critical literature that seeks to advance migrants’ rights, arguing that experiencing, encountering and escaping entrapment processes in the emigration regime impacts their agency when navigating immigration regimes and labor relations. This contribution advances the existing efforts to establish oft-ignored emigration regimes as important epistemological sites of research, theorization, and intervention.
Adjudicating labor mobility under France’s agreements on the joint management of migration flows: How courts politicize bilateral migration diplomacy
Authors: Panizzon Marion
Published: August 2022

France’s agreements on the joint management of migration flows (AJMs) figure centrally within studies of bilateral migration agreements. With their origins in friendship and navigation treaties of the late 19th century, the AJMs are successors to the postcolonial, circular mobility conventions of the 1960s, and are uniquely positioned for periodizing the evolution of bilaterally negotiated labor mobilities. Nonetheless, due to the European Union’s reluctance to embrace mass regularization and the EU Member States’ legislative powers over labor markets, they have time and again scotched France’s ambition to leverage preferential labor market entries in exchange for more cooperation over irregular migration. Through documents and statistical data analysis, this Article studies the case of Senegal’s negotiation of additional pathways to France for its lower-skilled workers. At the center is France’s administrative court of appeals, which has confirmed the broad margin of discretion over Art. 42 in the AJM between France and Senegal. This jurisprudence has decoupled the automatic linkage between a job listed under duress in France under the Annex to the AJM and the entitlement to exceptional admission. We argue that France’s courts have removed a privilege of Senegalese workers, which has re-politicized France’s migration diplomacy with Senegal. At the same time, retention of the prefectorial discretionary power has levelled the playing field among West and North African countries that have concluded similar bilateral agreements with France. This Article adds to the research on bilateral migration agreements by proposing a multilevel legal analysis, which studies AJMs in the context of France’s common law, EU labor and return directives, and the multilateral of WTO/GATS liberalization.
Narrative Ökonomik: Europa als „Transferunion“ oder „Risikogemeinschaft“?
Authors: Neuberger Doris , Beretta Edoardo
Published: August 2022

Economic developments are often accompanied by narratives, which correspond to popular or generally understandable as well as easily reproducible descriptions, images and interpretations. In debates about European integration, the sovereign debt crisis, and solutions to the Corona crisis – the latter of which has rekindled concerns about the public finances of thrifty states – the narrative of Europe as a “transfer union” plays a major role. Unilateral payments from economically strong to economically weaker countries are assumed. An evaluation of all plenary minutes of the German Bundestag shows that this narrative has spread since the introduction of the Euro. Its peak has been reached with the European sovereign debt crisis of 2010/11. However, this is a distorted picture, which identifies Germany as the loser of European integration. The advantages to all member States deriving from currently discussed – or already implemented – measures to stabilize the EU can be explained by means of more appropriate descriptions of Europe as a “stability union” or “risk community”.
Supplier Incentive Considering Overconfidence of Main Manufacturers from the Perspective of Capability Maturity of Intelligent Manufacturing
Authors: Shi Li , Liu Yuan
Published: August 2022

In the process of intelligent manufacturing transformation and upgrading, the main manufacturer’s cognitive deviation of its intelligent manufacturing level leads to overconfidence, which affects the collaborative efficiency of intelligent manufacturing supply chain and the profits of other supplier members. This article considers the risk of overconfidence behavior of the main manufacturer and conducts supplier incentive research from the perspective of intelligent manufacturing capacity maturity. Firstly, the index system is constructed based on the intelligent manufacturing capability maturity theory, and then the overconfidence degree of the main manufacturer is judged through the clustering image of t-distributed stochastic neighbor embedding algorithm. Then, based on the Stackelberg game idea, the overconfidence coefficient of the main manufacturer and the supplier incentive factor are introduced to construct the supplier incentive model to test the overconfidence of the main manufacturer. Finally, an example is given to verify the effectiveness of the proposed model.

Measures of Spatial Orientation: Spatial Bias Analogs in Visual and Haptic Tasks
Authors: Kim Min Jung , Otero-Millan Jorge , Tian Jing , Kheradmand Amir
Published: August 2022

The primary sensory modality for probing spatial orientation can vary among psychophysical tasks. In the subjective visual vertical (SVV) task, a visual stimulus is used to measure perceived vertical orientation, while a haptic stimulus is used in the subjective haptic vertical (SHV) task. Here we examined disparity in SHV and SVV task results and asked whether it could be related to biases in probing different spatial estimates by each task. Forty-two healthy volunteers (mean ± SD age, 25 ± 10 years; 19 females; 21 left handed) were recruited. The effect of a task to measure spatial orientation was calculated as the difference between SHV and SVV values, and with the head upright and tilted 20° laterally. There was a task bias regardless of head position related to hand use in the haptic task but not handedness (mean head upright ± SEM: left hand, −3.7 ± 1.1°; right hand, 7.9 ± 1.0°). When this task bias was subtracted out, there was a similar spatial bias using each hand in the SHV task that was also comparable to the SVV task (mean head with left tilt: left hand, 3.9 ± 0.7°; right hand, 4.4 ± 0.7°; SVV, 4.9 ± 0.7°; mean head with right tilt: left hand, −4.6 ± 0.9°; right hand, −4.6 ± 0.8°; SVV, −4.7 ± 1.0°). These findings show that the disparity in visual and haptic measures of spatial orientation is primarily related to a modality-specific bias, and once the effect of hand use is removed from the haptic measurements, the spatial bias becomes comparable to the visual task.
Educación para la cultura de paz en el contexto de Los Pastos, Colombia
Authors: Mesa-Manosalva Edgar Guillermo
Published: August 2022

Objetivo. Analizar las cosmovisiones de la Pachamama, minga colectiva, religiosidad popular, cuento pastuso y Carnaval de Negros y Blancos en el contexto de los Pastos para consolidar la cultura de paz en el marco del acuerdo final para la terminación del conflicto y la construcción de una paz estable y duradera. Metodología. Se realizó una investigación con enfoque cualitativo y etnográfico con miras a la descripción del estilo de vida, comprensión e interpretación de la realidad humana y social, y sus implicaciones educativas en diversos escenarios. Se eligió a un selecto grupo de docentes para las entrevistas en profundidad, a personas campesinas e indígenas para las entrevistas informales, y la observación participante en municipios de ascendencia pastusa. La información se estructuró en cuatro categorías inductivas en el programa de análisis de datos cualitativos Atlas. Ti. Resultados. Los principales resultados indican que las cosmovisiones podrían ser referentes teórico-prácticos necesarios y pertinentes para la resolución y transformación de los conflictos y para la educación y consolidación de la cultura de paz. Conclusión. Los referentes conceptuales son importantes para valorar el colectivismo económico, social y cultural; conservar el equilibrio, la armonía, la reciprocidad y la complementariedad; promover el tejido social, la pervivencia y el buen vivir; y gestionar la fiesta, el buen humor y la felicidad. Se recomienda conocer los contextos étnico-culturales para ofrecer una educación integral, libertaria, emancipadora y contextualizada.

Introducción. En educación médica es importante el desarrollo de competencias que propicien el aprender a aprender a través de estrategias flexibles como la formación investigativa. Objetivo. Determinar la relación entre formación investigativa, fortalecimiento del aprendizaje autónomo y gestión del tiempo en estudiantes de medicina. Metodología. Diseño mixto, componente cuantitativo (transversal analítico) y componente cualitativo (grupos focales y entrevista). Se incluyeron 110 estudiantes de los últimos semestres, que firmaron consentimiento informado. Se aplicaron tres instrumentos: sociodemográfico-académico, escala de preparación al aprendizaje independiente y manejo del tiempo. Se realizó análisis descriptivo de las variables y se compararon los puntajes obtenidos, entre estudiantado vinculado o no a procesos de investigación, mediante la prueba t de student. Resultados. De los sujetos participantes, 60,6% fueron mujeres; 94,5% no trabajaban, y 85,5% provienen de colegio particular pagado. En su mayoría, el estudiantado posee acceso a computador e internet, 96,4% y 98,2%, respectivamente. El estudiantado vinculado a procesos de investigación obtuvo puntajes más altos en la escala de aprendizaje independiente que aquel no vinculado (diferencia medias: 7, IC95%:1-13, p=0,02), en aspectos relacionados con el deseo de aprender (p=0,004). De igual manera, hubo diferencias marginales en la gestión del tiempo (diferencia medias: 4,3, IC95%:0,2-8,5; p=0,04), relacionadas con planificación a corto plazo (p=0,03). En las entrevistas y grupos focales el estudiantado resaltó las competencias en análisis crítico desarrolladas en los cursos de investigación. Conclusiones. El estudiantado vinculado a investigación tiene mayores puntajes en la escala EPAI y TQM, se evidencia que la investigación potencia habilidades relacionadas con el aprendizaje autodirigido y la gestión del tiempo.
