Prácticas de aprendizaje experiencial en la formación de estudiantes de pregrado universitario en comunicación de las organizaciones
No full textImplementar el aprendizaje experiencial en las universidades ha demandado procesos de actualización de los profesores, en quienes recae la tarea de sacar provecho de todas las bondades y posibilidades de este modelo formativo. La presente investigación se ha orientado a conocer cómo entienden e implementan el aprendizaje experiencial los profesores universitarios que trabajan en programas de pregrado en comunicación de las organizaciones en Colombia. La metodología seguida consistió en entrevistas semiestructuradas en profundidad aplicadas a 28 profesores de 12 universidades colombianas. La información obtenida se analizó mediante la creación y aplicación de códigos creados a partir de variables tomadas del modelo teórico asumido para el análisis, de la revisión de la literatura y de las respuestas de los entrevistados, utilizando el software Atlas.ti. Los resultados indican que los profesores de la muestra conocen en qué consiste el aprendizaje experiencial, valoran notablemente las metodologías asociadas a él y las implementan. Sin embargo, para optimizar su aplicación, deberán ampliar el tiempo que dedican a cada momento del proceso, incluir una mayor diversidad de actores en él y fortalecer mecanismos de análisis y reflexión por parte de los estudiantes, sobre las experiencias vividas
O papel dos enclaves fortificados na reprodução de um modelo neoliberal de urbanização
No full textQual o papel dos enclaves fortificados na reprodução de um modelo neoliberal de urbanização? De que forma exatamente um fenômeno está associado ao outro? Partindo do estudo paradigmático de Teresa Caldeira sobre a cidade de muros, nosso objetivo central neste texto consiste em analisar a relação de convergência entre os enclaves fortificados e o processo de neoliberalização do espaço urbano. A despeito de todos os avanços verificados na agenda de pesquisa sobre segregação urbana e espaço público nas últimas décadas decorrentes do trabalho de Caldeira, consideramos que a relação entre os enclaves fortificados e a neoliberalização do urbano ainda é um ponto subteorizado nesse debate. Nosso argumento é que, embora os enclaves não estejam, em sua origem, diretamente relacionados ao neoliberalismo, a sua consolidação na paisagem urbana tem contribuído de forma relevante para a reprodução de um modelo de cidade cada vez mais neoliberalizado, reconfigurando o espaço público e a própria vida urbana em conformidade com o ethos do mercado
Storage of embryos and in vitro development of embryonic axes in avocado
No full textThe in vitro establishment of Persea americana embryonic axes is critical for micropropagation and biotechnological applications, particularly following seed storage. This study aimed to evaluate the effects of seed storage duration and culture media composition on the in vitro development of P. americana (‘Toro Canyon’ and ‘Duke 7’ cultivars) embryonic axes in MS (Murashige & Skoog 1962), MSm (30 % of macronutrient reduction) or SHm (modified from Schenk & Hildebrandt 1972) media. Morphological parameters, including embryo and embryonic axis length, width and mass, were recorded. The in vitro assessments included survival, rooting and rosette formation. The experiment followed a completely randomized design, with four replicates. The ‘Duke 7’ seeds were longer and heavier than the ‘Toro Canyon’ seeds, but did not produce significantly larger embryos. Without storage, ‘Duke 7’ exhibited a higher survival in SHm and lower rooting in MS, while ‘Toro Canyon’ showed no significant differences in survival or development among the media, except for lower rooting in SHm. Storage duration and packaging type did not significantly affect survival or rooting percentages, but influenced the rosette explant formation, which was lower in MS. After six months of storage, the ‘Duke 7’ embryonic axes maintained 93 % of viability, with 31 % forming rosettes and 69 % rooting. These findings suggest that the storage viability depends more on culture medium composition than seed biometry
Carcinoma de célula de Merkel gigante: relato de um caso atípico
No full textO carcinoma de células de Merkel é um câncer neuroendócrino cutâneo raro e agressivo que acomete a pele fotodanificada de pacientes brancos e idosos, apresentando-se geralmente como uma placa ou nódulo solitário na região da cabeça e do pescoço. Relatamos uma apresentação incomum do carcinoma de Merkel, com o surgimento simultâneo de dois tumores primários na região do tronco, em paciente negro
Assessment of the Global Integration Method on the parents’ perception of functional goals in children and adolescents with autism
No full textObjective: To investigate parents’ perception of performance and satisfaction with functional goals for children with ASD after intervention with the Global IntegrationMethods: This single-group quasi-experimental study involved a total of 98 participants aged 1.8 to 18.2 years who underwent a 3-month intervention, five times a week, for 3-4 h per day. The intervention involved functional task training in an environment inspired by the natural environment associated with the use of a flexible therapeutic suit. The primary outcome measure was the Canadian Occupational Performance Measure, administered before and after the intervention.Results: Ninety-five participants completed the study. Approximately 60% of participants showed improvements in performance and satisfaction that ranged from 1 to 9 points on the Canadian Occupational Performance Measure. The Global Integration Method program resulted in significant improvements in goal performance (p<0.001, d=0.80) and satisfaction (p<0.001, d=0.67). Most parents (81%) believed that the Global Integration Method incorporated aspects of family-professional collaboration and were satisfied (93%) with the intervention.Conclusion: In the perception of parents, the Global Integration Method demonstrated effectiveness in achieving functional goals for children with ASD and their families. Parents expressed satisfaction with the intervention and indicated that it incorporated elements of family-professional collaboration
Intranasal insulin in Alzheimer disease (diabetes in situ?): a systematic review and meta-analysis
No full textObjective: To evaluate the efficacy and safety of INI therapy for AD through a systematic review and meta-analysis of randomized controlled trials.Methods: A search of electronic databases, including PubMed, Web of Science, Scopus, and Embase, was conducted to identify relevant studies published up to June 2024. Inclusion criteria encompassed peer-reviewed original research articles focused on humans, investigating the therapeutic effects of INI administration on cognitive impairment associated with AD, and reporting quantitative data on cognitive outcomes, biomarkers, or pathological markers relevant to AD. A meta-analysis was conducted to quantitatively synthesize the effects of INI on cognitive outcomes.Results: A total of 647 articles were identified, and eight studies met the inclusion criteria. The overall odds ratio was 3.75 (95%CI 1.49–9.40). The test for overall effect showed a statistically significant difference (p<0.05). However, the I 2 value indicated a high level of heterogeneity (85.5%), suggesting significant variability among the studies. Conclusion: While the current data is not yet conclusive enough to definitively establish INI as a standard treatment for AD, the evidence supporting its safety, efficacy, and reduced risk of systemic side effects suggests potential cognitive benefits for improving global cognition in patients with AD
