Peer Leaders’ Perceptions of Learning Experiences

Peer-Led Team Learning (PLTL) at Florida International University maintains a large volume of student and Peer Leader (PL) participation. Students, who participate in PLTL, on average, perform a letter grade better than their peers who do not participate in PLTL. To analyze PL perspectives on learning, a survey was conducted. The survey had a series of Likert scale statements and free response questions on learning. The nature of the questions are regarding barriers in education, individual learning strengths and weaknesses, and the perception that PLTL improved the learner’s capabilities to overcome these obstacles. Based on the survey responses, PLs perceive an improvement in the way they learn during and/or after becoming a PL. Students participating in PLTL exhibited an increase in course content retention and perceived improvement in study skills. Students in PLTL also perceived the PLTL workshop environment to be comfortable enough to address questions and misconceptions

Crystal structure of methyl N-ferrocenylcarbamate

The asymmetric unit of the title compound, [Fe(C5H5)(C7H8NO2)], contains two independent molecules consisting of a ferrocenyl moiety and a nitrogen-bound methyl carbamate. These units are almost perpendicular to each other, making dihedral angles of 87.74 (9) and 87.32 (8)°. In each independent molecule, the cyclopentadienyl rings deviate slightly from an eclipsed conformation and lie virtually parallel [dihedral angles = 1.42 (15) and 0.49 (13)°]. In the crystal, molecules are linked by N—H...O hydrogen bonds into chains along the a-axis direction

Liderazgo del funcionario y satisfacción laboral según personal administrativo y asistencial del hospital Víctor larco Herrera - 2013

El objetivo de la investigación fue Determinar la relación que existe entre el Liderazgo del funcionario y la satisfacción laboral según el personal administrativo y asistencial del Hospital Víctor Larco Herrera - 2013, el estudio se realizó en el contexto de la búsqueda permanente de conocimientos respecto a la gestión organizacional en tiempos de cambios y capacitaciones permanentes promovidos por el Ministerio de Salud, considerando para ello la importancia del liderazgo que representa los funcionarios de las distintas organizaciones públicas. En este estudio particularmente se asumió el método hipotético deductivo de diseño no experimental transversal correlacional en la cual se aplicó un instrumento tipo escala de Likert para medir la percepción del nivel de Liderazgo de los Funcionarios y otro instrumento para recolectar datos de la satisfacción laboral de acuerdo a la percepción de los sujetos considerados como muestra de estudio. Las conclusiones arribadas indican que en las instituciones analizadas existe un nivel de liderazgo fuerte así como una correlación directa positiva y altamente significativa al nivel de ,000 entre estas dos variables analizadas

Influence of climate variables on resin yield and secretory structures in tapped Pinus pinaster Ait. in central Spain

The role of climate and soil water availability on resin yield was evaluated. Resin yield increased with temperature, radiation and evapotranspiration values. Resin yield and axial canal size were correlated with water deficit in spring. Above a certain threshold of cumulated water deficit, summer rainfall favored resin yield. Stand density and soil quality affected the relations between climate and resin yield

Quantitative indices of student social media engagement in tertiary education: a systematic review and a taxonomy

Recent studies have evaluated the use of social media as learning aids in tertiary education. Emerging research in this area has focused primarily on non-quantitative approaches to student social media engagement. However, quantitative engagement outcomes may be extracted from student posts, comments, likes, and views. The goal of the present review was to provide a research-informed taxonomy of quantitative and behavior-based metrics of student social media engagement. We selected 75 empirical studies comprising a pooled sample of 11,605 tertiary education students. Included studies used social media for educational purposes and reported student social media engagement outcomes (source databases: PsycInfo and ERIC). We used independent raters and stringent interrater agreement and data extraction processes to mitigate bias during the screening of references. Over half of the studies (52%, n =39) utilized ad hoc interviews and surveys to estimate student social media engagement, whereas thirty-three studies (44%) used some form of quantitative analysis of engagement. Based on this literature, we present a selection of countbased, time-based, and text-analysis metrics. The proposed taxonomy of engagement metrics resulting provides the methodological basis for the analysis of social media behavior in educational settings, particularly, for human operant and behavioral education studies.

Dexamethasone-Loaded Lipomers: Development, Characterization, and Skin Biodistribution Studies

Follicular targeting has gained more attention in recent decades, due to the possibility of obtaining a depot effect in topical administration and its potential as a tool to treat hair follicle-related diseases. Lipid core ethyl cellulose lipomers were developed and optimized, following which characterization of their physicochemical properties was carried out. Dexamethasone was encapsulated in the lipomers (size, 115 nm; polydispersity, 0.24; zeta-potential (Z-potential), +30 mV) and their in vitro release profiles against dexamethasone in solution were investigated by vertical diffusion Franz cells. The skin biodistribution of the fluorescent-loaded lipomers was observed using confocal microscopy, demonstrating the accumulation of both lipomers and fluorochromes in the hair follicles of pig skin. To confirm this fact, immunofluorescence of the dexamethasone-loaded lipomers was carried out in pig hair follicles. The anti-inflammatory (via TNFα) efficacy of the dexamethasone-loaded lipomers was demonstrated in vitro in an HEK001 human keratinocytes cell culture and the in vitro cytotoxicity of the nanoformulation was investigated

El marketing de contenidos y la decisión de compra de productos cosméticos importados en mujeres millennials de Lima Metropolitana 2023

El presente trabajo de investigación titulada “El marketing de contenidos y la decisión de compra en productos cosméticos importados en mujeres millenials de Lima Metropolitana 2023” El propósito es examinar la conexión que se establece entre el marketing de contenidos y la decisión de compra de productos cosméticos importados en las mujeres millenials de Lima Metropolitana 2023. Se utilizó la metodología de enfoque cuantitativo con un enfoque no experimental, contando con un diseño correlacional. La población que se calculó de acuerdo con el CPI es de 1,293,471 de mujeres, asimismo realizando el cálculo de muestra aleatoria simple utilizando un margen de error de 5.87 se obtuvo 280 mujeres. La técnica que se empleó para recopilar información del público objetivo se realizó mediante encuestas con un total de 33 preguntas. De los resultados se obtuvo que al hallar la credibilidad mediante Alfa de Cronbach tuvo una confiabilidad muy buena debido a que los valores de cada variable se acercan a 1. Por otro lado, se aplicó el coeficiente de correlación Spearman dando como resultado 0.792 llegando a la conclusión que si existe una relación entre ambas variables. En conclusión, para lograr la fidelización de los consumidores, Las compañías deben dirigir sus estrategias de marketing hacia la creación de contenido valioso y que se adapte a las necesidades identificadas.The present investigation entitled "Content marketing and the purchase decision of imported cosmetic products in millennial women of Metropolitan Lima 2023" The purpose is to examine the connection established between content marketing and the purchase decision of cosmetic products. imported into millennial women of Metropolitan Lima 2023. The quantitative approach methodology was used with a non-experimental approach, with a correlational design.
