Towards a Pedagogical Model Applying Commedia dell’Arte and Art Workshops in Higher Education Design Studies
Authors: Haapaniemi Heini , Leinonen Teemu
Published: September 2023

This study introduces a pedagogical model: “the parallel co-inquiry cycles with performative inquiry for character related design” for higher education design studies that focus on characterization. The disciplines benefitting from cross-fertilization provided by the model include game design, fashion design, graphic design, theatre, and actor’s art. Besides the model, the article discusses curriculum integration of a shared thematic denominator Commedia dell’Arte in higher education design studies. The model synthesizes progressive inquiry, drama pedagogical methodologies, and theories on theater with hands-on art workshops to create tangible and digital knowledge vessels for characterization. The research design relies on parallel co-inquiry cycles, participatory ethnography with elements from participatory design tradition. The model identifies three major components within the single 3E-inquiry cycles, namely exercise, experiment and experience. The entire process acquires complexity as each single inquiry cycle enters the next loop of Observe–Plan–Act–Reflect and more time and resources are allocated to the process. The pattern of action and reflection has an iterative cycle format in this model. Reflection has two distinguished purposes: first, to internalize reflective design and to become a reflective practitioner. Second, to see the importance of reflection as distancing oneself from the current process, to allow a reflective mind to linger on the process and learn from mistakes to turn them into assets. Reflection as a metacognitive skill has an all-encompassing purpose in both design and learning processes. The model distinguishes two types of knowledge vessels. Knowledge objects are abstractions that condense knowledge in the co-design process, whereas knowledge artifacts are concrete items, such as masks, outfits, and accessories in both digital and tangible formats. The model connects maker-culture, practice-based inquiry, and performative inquiry in the inquiry cycles. The drama method with performative inquiry acknowledges shared knowledge building in a collaborative, dialogical inquiry that fosters both argumentative and reflection skills.

Published: September 2023

Flame-retardant impregnation and densification are two major modification techniques to improve the fire safety of wood. Here, these two techniques were combined to prepare flame-retarded wood, aiming at further fire hazard reduction. The delignated Pinus sylvestris L. was impregnated with boric acid (BA) and graphene oxide (GO) solutions, then densified to prepare densified flame-retarded wood named BGO-DW sample. The results revealed that the BGO-DW sample obtained a limiting oxygen index (LOI) value of 47.4 %. Its backside temperature after 1200 s heating was 49 % lower than that of unmodified wood. Besides, the peak heat release rate (PHRR) and total heat release (THR) values of BGO-DW sample were 72 and 62 % lower than those of unmodified wood due to its shorter pyrolysis interval and lower peak mass loss rate (PMLR), as supported by thermogravimetric (TG) analysis. The flame retardancy of BGO-DW sample could be attributed to the formation of compatible char containing C=C aromatic structure, C–O–C cross-linked structure, and boron trioxide (B2O3) structure. These features of BGO-DW sample offer a new method to improve thermal stability, heat insulation, and flame retardancy for wood and wood-based products.

mRNA translation is tightly regulated by various classes of RNA-binding proteins (RBPs) during development and in response to changing environmental conditions. In this study, we characterize the arginine-glycine-glycine (RGG) motif containing RBP family of Arabidopsis thaliana representing homologues of the multifunctional translation regulators and ribosomal preservation factors Stm1 from yeast (ScStm1) and human SERBP1 (HsSERBP1). The Arabidopsis genome encodes three RGG proteins named AtRGGA, AtRGGB and AtRGGC. While AtRGGA is ubiquitously expressed, AtRGGB and AtRGGC are enriched in dividing cells. All AtRGGs localize almost exclusively to the cytoplasm and bind with high affinity to ssRNA, while being capable to interact with most nucleic acids, except dsRNA. A protein-interactome study shows that AtRGGs interact with ribosomal proteins and proteins involved in RNA processing and transport. In contrast to ScStm1, AtRGGs are enriched in ribosome-free fractions in polysome profiles, suggesting additional plant-specific functions. Mutant studies show that AtRGG proteins differentially regulate flowering time, with a distinct and complex temperature dependency for each AtRGG protein. In conclusion, we suggest that AtRGGs function in fine-tuning translation efficiency to control flowering time and potentially other developmental processes in response to environmental changes.
Microtubules as a signal hub for axon growth in response to mechanical force
Authors: Falconieri Alessandro , Coppini Allegra , Raffa Vittoria
Published: September 2023

Microtubules are highly polar structures and are characterized by high anisotropy and stiffness. In neurons, they play a key role in the directional transport of vesicles and organelles. In the neuronal projections called axons, they form parallel bundles, mostly oriented with the plus-end towards the axonal termination. Their physico-chemical properties have recently attracted attention as a potential candidate in sensing, processing and transducing physical signals generated by mechanical forces. Here, we discuss the main evidence supporting the role of microtubules as a signal hub for axon growth in response to a traction force. Applying a tension to the axon appears to stabilize the microtubules, which, in turn, coordinate a modulation of axonal transport, local translation and their cross-talk. We speculate on the possible mechanisms modulating microtubule dynamics under tension, based on evidence collected in neuronal and non-neuronal cell types. However, the fundamental question of the causal relationship between these mechanisms is still elusive because the mechano-sensitive element in this chain has not yet been identified.

Authors: Wu Di , Ge Yanlin , Chen Lingen , Tian Lei
Published: September 2023

Based on the irreversible Otto cycle model, applying finite-time-thermodynamic theory, this paper takes power and efficiency as the objective functions, further studies the cycle performance under the condition of non-ideal gas working fluid, analyzes the effects of different loss items and freedom degree (d) of monatomic gas on the cycle performance, and compares performance differences of ideal gas and non-ideal gas under different specific heat models. The results demonstrate that, with the increase ofd, the maximum-power-output (Pmax), the maximum-thermal-efficiency (ηmax), the corresponding optimal compression-ratio ((γopt)p${({\gamma }_{\text{opt}})}_{p}$) and efficiency (ηP) at thePmaxpoint, and the corresponding optimal compression ratio ((γopt)η${({\gamma }_{\text{opt}})}_{\eta }$) and power (Pη) at theηmaxpoint will all increase; thePmax,(γopt)p${({\gamma }_{\text{opt}})}_{p}$,ηmax,(γopt)η${({\gamma }_{\text{opt}})}_{\eta }$,ηpandPηwill decrease with the increases of three irreversible losses; the specific heat model has only quantitative effect on cycle performance but no qualitative effect; under condition of non-ideal gas specific heat model, the power and efficiency are the smallest.
Comparative analysis of optical data center switches
Authors: Sinha Amit , Bhardwaj Diwakar , Shukla Vaibhav
Published: September 2023

In the recent past, there has been an explosive growth in data traffic within data center systems. This rapid increase in data volume has put significant constraints on the speed of current data communication networks, which are predominantly based on electronic controllers and memory. The speed limitations of electronic devices hinder their ability to process data at higher rates efficiently. To address this issue and enable faster data processing, the use of optical communication emerges as the most promising solution. Optical communication leverages the capabilities of light signals and optical components, which can handle data at much higher rates compared to their electronic counterparts. One key element in optical communication systems is the utilization of fiber delay lines (FDLs) as optical storage for packets. FDLs offer the ability to temporarily store and delay optical signals, providing buffering capabilities within optical networks. These FDLs can be configured in various setups, including feed forward, feed backward, and recirculating configurations, each with its own set of advantages and disadvantages. In this context, this article explores several state-of-the-art arrayed waveguide grating (AWG)-based optical packet switch (OPSW) architectures. These switches are designed to efficiently route and manage optical packets within data center networks. Each architecture is summarized, highlighting its unique features and capabilities. To compare the different AWG-based OPSW architectures, various key parameters are considered, such as the cost, physical losses, bit error rate (BER), and the number of tunable components required. These parameters are critical in determining the performance, efficiency, and cost-effectiveness of the switches.
Ultra-long haul high speed 96 × 40 GB/s radio over IsOWC system employing advanced modulation scheme
Authors: Parkash Sooraj
Published: September 2023

This paper successfully demonstrates that point-to-point (P2P) superdense wavelength division multiplexing (SDWDM) based on the radio over intersatellite optical wireless communication (Ro-IsOWC) system of 96 channels separated by a 100 GHz bandwidth with 40 GB/s data rate on each stream at a 10,000 km link range has been designed and investigated. The performance of the proposed work has been evaluated by considering the comparison of advanced modulation schemes such as carrier-suppressed return-to-zero (CSRZ), duobinary return-to-zero (DRZ), and modified duobinary return-to-zero (MDRZ) with an optical preamplifier on the bases of bit error rate (BER), quality factor, eye height, and optical signal-to-noise ratio (OSNR) in the clear weather condition. Moreover, the effects of internal parameters such as transceiver aperture diameter and gain of an optical amplifier also have been analyzed with an optimized modulated system. Apart from this, the system performance also has been assessed under varying data rates and OWC frequency ranges with the best-suited modulation format. It has been found that the CSRZ modulation format has shown robust performance and can achieve BER as better as 10−09 with a 5.5 dB quality factor for all wavelengths. It also has been observed that the quality of the received signal deteriorates below an unacceptable value for data rate and link distance beyond 40 GB/s and 10,000 km, respectively.

Published: September 2023

Objectives

To compare pregnancy complications in pregnancies with and without pre-gestational diabetes mellitus (DM) managed in a multidisciplinary high-risk diabetes antenatal clinic.

Methods

This screening cohort study was undertaken at a large maternity unit in the United Kingdom between January 2010 and December 2022. We included singleton pregnancies that booked at our unit at 11–13 weeks’ gestation. Univariate and multivariate logistic regression analysis was carried out to determine risks of complications in pregnancies with type 1 and type 2 DM after adjusting for maternal and pregnancy characteristics. Effect sizes were expressed as absolute risks (AR) and odds ratio (OR) (95 % confidence intervals [CI]).

Results

The study population included 53,649 singleton pregnancies, including 509 (1.0 %) with pre-existing DM and 49,122 (99.0 %) without diabetes. Multivariate logistic regression analysis demonstrated that there was a significant contribution from pre-existing DM in prediction of adverse outcomes, including antenatal complications such as fetal defects, stillbirth, preterm delivery, polyhydramnios, preeclampsia and delivery of large for gestational age (LGA) neonates; intrapartum complications such as caesarean delivery (CS) and post-partum haemorrhage; and neonatal complications including admission to neonatal intensive care unit, hypoglycaemia, jaundice and hypoxic ischaemic encephalopathy (HIE). In particular, there was a 5-fold increased risk of stillbirth and HIE.

Conclusions

The maternal and neonatal complications in pregnancies with pre-existing DM are significantly increased compared to those without DM despite a decade of intensive multidisciplinary antenatal care. Further research is required to investigate strategies and interventions to prevent morbidity and mortality in pregnancies with pre-gestational DM.
Experimental investigation of mechanical properties of PLA, ABS, and PETG 3-d printing materials using fused deposition modeling technique
Authors: Kopar Mehmet , Yildiz Ali Riza
Published: September 2023

In recent years, there has been a logarithmic interest in three-dimensional printing technologies. This technique has made it possible to make more intricately shaped parts of superior quality, allowing for use in a variety of industries, including aircraft, automobiles, and ships. This study characterized the materials and assessed the mechanical features of PLA, PETG, and ABS materials generated at various raster angles. The strength ratios of the various materials have been found to fluctuate when the raster angles change. The PLA parts created at a picture raster angle of 45° had the maximum tensile strength. ABS material created with a picture raster angle of 45° has been shown to have the best energy absorption, and PLA material made with a raster angle of 45° has the best performance compressive strength. When bending strength was evaluated, it was found that samples of ABS made with a raster angle of 0–90° had the greatest value. The SEM micrographs were obtained, and the tensile test was used to examine the fracture behavior of the materials. As a result, it has been found that materials created using various raster angles can have various strength values from one another.

Three-dimensional visualisation of traffic noise based on the Henk de-Klujijver model
Authors: Wickramathilaka Nevil , Ujang Uznir , Azri Suhaibah , Choon Tan Liat
Published: September 2023

Visualisation of road traffic noise is vital for traffic noise planning policies. Several factors affect the noise from road traffic with physical and environmental conditions. Collecting noise levels around the world is not a possible task. Therefore, calculating noise levels by a valid noise model, and spatial interpolations, is prime to traffic noise visualisation. In this study, the Henk de Klujijver noise model is used. Designing noise observation points (Nops) embedding with a three-dimensional (3D) building model and identifying the best suitable spatial interpolation are important to visualise the traffic noise accurately. However, interpolating noise in 3D space (vertical direction) is a more complex process than interpolating in two-dimensional (2D) space. Flat triangles should be eliminated in the vertical direction. Therefore, the structure of Nop has a major influence on spatial interpolation. Triangular Irregular Network (TIN) interpolation is more accurate for visualising traffic noise as 3D noise contours than Inverse Distance Weighted and kriging. Although kriging is vital to visualise noise as raster formats in 2D space. The 3D kriging in Empirical Bayesian shows a 3D voxel visualisation with higher accuracy than 3D TIN noise contours.
Investigation into Na and Cs activity coefficients in high salt solutions to support Cs removal in Hanford tank waste
Authors: Campbell Emily L. , Westesen Amy M. , Peterson Reid A.
Published: September 2023

The treatment of Hanford tank waste is one of the most technically challenging environmental cleanup activities for the U.S. Department of Energy to date. To expedite the processing of liquid waste stored in underground tanks in southeastern Washington state, it is necessary to remove the significant dose contributor, 137Cs. Toward this effort, ion exchange with crystalline silicotitanate (CST) has been employed as part of the Tank Side Cesium Removal system. The model used to predict Cs exchange onto CST was developed using activity coefficients calculated from the Bromley equation. A series of batch contact tests that varied in [Na] were conducted to look at the impact of Na concentration on Cs distribution. Experimental distribution ratios (K
d) were compared to the distribution ratios predicted using three different activity coefficient models: (1) commercially available HSC software, (2) the Bromley equation, and (3) a simplified approach adapted from Marcos-Arroyo et al. Ultimately, the Bromley method underpredicted the effect of ionic strength on the Na activity coefficient (γ
Na+), HSC overestimated the impact of ionic strength on the expected performance due to the Cs activity coefficient (γ
Cs+), but the simplified approach predicted the experimental K
d values quite well in a binary matrix. Expansion of this approach in complex matrices is necessary for application to Hanford tank waste.
Imagen de China ante la opinión pública latinoamericana: memoria colectiva, sistema complejo y preferencia cognitiva
Authors: Dong Qingqing
Published: September 2023

Este artículo busca explicar la asincronía entre el estrechamiento de las relaciones económicas de China y América Latina y la evolución de la imagen de China en el contexto latinoamericano en el siglo XXI. Esto sugiere que, pese a que los factores económicos son indispensables en la percepción de la imagen nacional, no se puede asumir una relación causal lineal entre ambos variables. Por ello, el artículo adopta la perspectiva de sistemas complejos sobre la base de relajar la suposición de tomar preferencias cognitivas como invariables o exógenas para investigar el proceso de percepción de la imagen nacional combinando estímulos exteriores y cognición interior. La conclusión preliminar consiste en que el desarrollo de las relaciones económicas bilaterales basado en el creciente poder de China dentro del sistema complejo internacional, llevará a una sensación de privación relativa y ansiedad de seguridad entre el público latinoamericano con su preferencia de aversión al riesgo, lo cual causa finalmente resultados no intencionados.
Structural semiology, Peirce, and biolinguistics
Authors: Lacková Ľudmila
Published: September 2023

Peirce’s sign model is introduced as incompatible with structural semiology in the majority of semiotics textbooks. In this paper, I would like to argue against this general polarization of the semiotic discipline. I focus on compatibilities between Lucien Tesnière’s syntactic theory (verbal valency) and Peirce’s logic of relatives. My main argument is that structural linguistics is not necessarily dyadic, and that Peirce’s sign doctrine is perfectly structural. To define the structural approach in Peirce, I analyze the notions of form (structure) and substance in Hjelmslev and Peirce. The aim of my argument is to contribute to attempts to introduce Peirce’s theory to the field of linguistics in the hope that such an integration will be beneficiary for general linguistics. To extend and support my argument, I provide some examples from biology where Peirce’s theory has been applied. I demonstrate an analogy between the biological structures of proteins and the structure of a sentence with Peirce’s own writings. I consequently introduce Peirce as the first structural semiologist and as the first biolinguist.
Precision of Memory for Attended and Ignored Colors
Authors: Halewicz Victoria , Simons Daniel J.
Published: September 2023

Selective attention can enhance some aspects of our visual world while filtering others from awareness. Given our limited cognitive resources, such filtering is essential when viewing complex scenes, but it also applies to simple scenes. Eitam, Yeshurun, and Hassan (2013) observed better performance for the attended color than the ignored color in a simple, two-colored object even though both colors were salient and the complexity of the display did not tax the capacity of visual memory. Our goal was to replicate this finding while addressing a potential task demand that could have contributed to the results. Specifically, participants might have misread the instructions and mistakenly reported the attended color when asked to report the ignored color first. Experiment 1 (n=67) replicated Eitam et al.’s (2013) finding while measuring memory precision. We found that people had worse memory for the ignored than the attended feature of a single, simple object. Experiment 2 (n=69) replicated the pattern while again addressing the potential task demand, although the effect was smaller. Experiment 3 (n=186) provided visual feedback to eliminate any remaining risk of response error and again replicated the original finding. Attended information was stored with greater precision than unattended information, even for a simple object.

Human papillomavirus (HPV) infections are the cause of all cervical and numerous oropharyngeal and anogenital cancers. The currently available HPV vaccines, which induce neutralizing antibodies, have no therapeutic effect on established tumors. Here, we developed an immuno‐oncotherapy against HPV‐induced tumors based on a non‐integrative lentiviral vector encoding detoxified forms of the Early E6 and E7 oncoproteins of HPV16 and 18 genotypes, namely, “Lenti‐HPV‐07”. A single intramuscular injection of Lenti‐HPV‐07 into mice bearing established HPV‐induced tumors resulted in complete tumor eradication in 100% of the animals and was also effective against lung metastases. This effect correlated with CD8+ T‐cell induction and profound remodeling of the tumor microenvironment. In the intra‐tumoral infiltrates of vaccinated mice, the presence of large amounts of activated effector, resident memory, and transcription factor T cell factor‐1 (TCF‐1)+ “stem‐like” CD8+ T cells was associated with full tumor eradication. The Lenti‐HPV‐07‐induced immunity was long‐lasting and prevented tumor growth after a late re‐challenge, mimicking tumor relapse. Lenti‐HPV‐07 therapy synergizes with an anti‐checkpoint inhibitory treatment and therefore shows promise as an immuno‐oncotherapy against established HPV‐mediated malignancies.

Endometriosis as a highly relevant yet neglected gynecologic condition in Asian women
Authors: Velarde Michael C , Bucu Mikaela Erlinda M , Habana Maria Antonia E
Published: September 2023

Endometriosis is a chronic, debilitating disease characterized by the growth of endometrial tissues outside the endometrium. Its prevalence seems to differ across ethnicities, with the disease affecting and presenting with advanced stages in Asians more than any other race. Despite this, data on endometriosis in Asians is limited, and there seems to be a lack of support for endometriosis research in Asia. Hence, this review aims to consolidate the available literature on endometriosis in Asians to identify the gaps in knowledge regarding its occurrence in this population and emphasize the need to address the disease in this part of the world. Certain genetic, dietary, and environmental factors that predominate in Asians compared to other ethnicities may potentially impact endometriosis. Understanding these differences is essential in providing innovative strategies for reducing health disparities in endometriosis incidence and presentation across ethnic groups, thus improving disease management and health outcomes.
Vowel space in hypokinetic dysarthria
Authors: Gili Fivela Barbara , D’Apolito Sonia I. , Sigona Francesco
Published: September 2023

The paper discusses acoustic and articulatory data on the use of vowel space by speaker affected by Parkinson’s Disease who developed hypokinetic dysarthria. Two experiments involving pathological subjects and matching controls are described, whose general aim is to better understand if the vowel space in Parkinson’s Disease dysarthric subjects is always and homogeneously reduced. In the first investigation, acoustic and kinematic data are collected and analyzed to test if pathological speakers always use a reduced vowel space compared to control subjects, and if they adopt different articulatory strategies depending on the axis of the speech gesture (vertical vs horizontal). In the second investigation, various articulatory metrics are used to better investigate the dimension and position of the acoustic vowel space, and if they change in Parkinson’s Disease subjects compared to controls. Results show that reduction takes place, but some subjects appear to compensate, widening their tongue gestures on the horizontal axis even though the lip gesture is not necessarily undershot. Nevertheless, metrics used in the second experiment do not allow to capture a reduction, even though, in line with results of the first experiment, they point to an asymmetry in the vowel space used depending on the axis considered.
Information structure in the speech of individuals with schizophrenia

Published: September 2023

This paper focuses on information structure in the speech of individuals with schizophrenia, according to the theoretical framework found in the Language into Act Theory. A specific textual structure, called stanza, and its informational complexity, have been compared using two corpora: the C-ORAL-ESQ for pathological speech, and the C-ORAL-BRASIL for non-pathological speech. Firstly, we briefly explain the theory and the concept of stanza. Then, we explain in depth the methodology adopted for comparing pathological and non-pathological speech, using the two corpora. Additionally, we discuss the results found, part of which have statistical significance. Finally, we propose a first explanation of the results, focusing on cognitive and prosodic aspects that could provide insights for further research.

Published: September 2023

En este artículo se presenta el proceso y los resultados de una investigación de enfoque cualitativo que busca comprender las razones por las que algunas escuelas no logran que sus alumnos aprendan tanto como sería esperable teniendo en cuenta su contexto. Se trata de un estudio en profundidad en ocho escuelas "eficaces negativas" de Educación Primaria de otros tantos países iberoamericanos. Dichas escuelas fueron seleccionadas a partir de un estudio más amplio, de carácter cuantitativo y en el que se midió no solo su desempeño en áreas curriculares, como Lengua y Matemáticas, sino también diferentes variables socio-afectivas como el autoconcepto o el bienestar en la escuela bajo un planteamiento de valor agregado. Mediante la aplicación de grupos focales a docentes, estudiantes, y padres y madres, entrevistas semiestructuradas a docentes y directivos, y a través de la observación del aula y la escuela se consiguió una imagen holística. Entre los factores hallados se encuentra un clima negativo, la falta de compromiso y motivación, la sensación de desánimo, el poco trabajo en equipo del profesorado, una dirección ausente o autoritaria, la poca implicación de las familias, las bajas expectativas globales, los procesos de enseñanza reproductivos, e instalaciones inadecuadas y desatendidas.

O Programa de Português dos Cursos Profissionais de nível secundário decorre da reforma curricular de 2004 e inscreve-se numa série de iniciativas que tiveram largo alcance na natureza da educação, optando pela metodologia cognitivista/construtivista/humanista e por estratégias cognitivas e metacognitivas. Este estudo pretende comprovar se os professores põem em prática as metodologias e as estratégias propostas pelo programa. Utilizámos métodos quantitativos e qualitativos e fizemos a posterior triangulação, ampliando e completando a produção de conhecimento e aportando informação acrescida. Apesar da proposta da metodologia consignada no texto programático e das estratégias específicas para desenvolver competências, os professores utilizam, preferencialmente a metodologia transmissiva, caracterizada como prática apresentativa de conteúdos declarativos, perpetuam as suas práticas pedagógicas, “ensinando todos como se fossem um só” e partindo do princípio que os alunos não são capazes de realizar tarefas complexas o que pode impedir o desenvolvimento da sua plena autonomia.

La necesidad de evidencia empírica (cualitativa) en el contexto andaluz impulsa el objetivo del estudio: analizar las percepciones y valoraciones de los actores educativos acerca del impacto de las PED en los centros escolares. La investigación se realizó en seis centros de educación primaria públicos de la Provincia de Granada (Andalucía) diferenciados geográficamente y por tipo de alumnado. Se utilizo metodología cualitativa y “análisis de contenido” para reducir los datos. Los resultados reflejan las categorías emergentes. Su índice de frecuencia categorial (IFC) evidenció que el efecto del diagnóstico se incrementa mientras la tipología del centro decrece. También permitió organizar las sub-categorías en relación con su grado de impacto.

Este artículo analizará la red social que configura el profesorado en seis centros de educación primaria andaluces, así como la modalidad de distribución del liderazgo que aparece en cada una de las redes. Nuestro propósito al utilizar la metodología de Análisis de Redes Sociales (ARS) en el marco de un proyecto más amplio sobre alcance y patrones de distribución del liderazgo en los centros escolares era conocer mejor la trama de relaciones sociales que sustenta al liderazgo escolar. Para ello elaboramos y administramos al profesorado participante un Cuestionario sobre la Red Social del Centro Escolar (CURSO) en el que se indaga sobre las relaciones docentes en cuatro ámbitos: enseñanza, gestión escolar, convivencia y apoyo individual. Los datos fueron analizados mediante el programa UCINET. El análisis se realizó a partir del grado de centralidad de los actores implicados en cada red, así como de varias propiedades estructurales de las mismas como su densidad, centralización y número y composición de los cliques o grupos participantes. Los resultados nos permitieron identificar diversas configuraciones relevantes del liderazgo escolar: focalizado, múltiple, alternativo y sin-liderazgo. Finalmente se aportan algunas conclusiones sobre la relevancia de la metodología de análisis de redes sociales para el estudio del liderazgo. The Social Fabric of Leadership. A Study of Teachers’ Collaboration Networks in Primary SchoolsThis paper will analyse the social network emerging from teachers’ relationships in six Andalusian primary schools, and will identify the leadership distribution pattern of each network. Our aim using Social Network Analysis methodology in the framework of a wider research project about patterns and scope of school leadership distribution was to better know the web of social relationships that sustain school leadership. To do this, a School Social Network Questionnaire was designed and administered to the whole staff of the participating schools. The questionnaire included questions regarding four areas: teaching, school management, social relationships and personal support. Data collected were analysed by means of UCINET software. The analysis focused both on the actors’ centrality degree and several structural properties of the networks, such as their density, centralisation, and the number and composition of the cliques or groups participants. The results allowed the research team to identify some relevant patterns of school leadership: focused, multiple, alternative, and leadership void. Finally some conclusions are presented about the relevance of social network analysis in leadership studies.Keywords: Distributed leadership, Leadership patterns, Management team, Social network analysis.
La Implementación de los Social Media como Recurso Docente en la Universidad presencial: La perspectiva de los Estudiantes de Comunicación
Authors: Aymerich-Franch Laura , Fedele Maddalena
Published: September 2023

Se presentan los resultados de una investigación sobre la opinión de los estudiantes relativa al uso de los medios de comunicación social (MCS) como recurso docente en la universidad presencial. Se realizó una encuesta a 244 estudiantes del área de Comunicación (M=20.67) y cuatro focus groups con 30 participantes. Mayoritariamente, los estudiantes se muestran a favor de la implementación de los MCS como recurso docente en la universidad. No obstante, se identifican los siguientes temores entre los estudiantes: pérdida del contacto cara a cara entre alumnos y profesores, saturación mediática, dependencia de internet y conflictos de privacidad. Emplear los MCS para incentivar la participación (creación de foros de debate) y como soporte de contenidos y material docente (blogs, servidores multimedia y grupos en redes sociales) son las prácticas que mejor se valoran mientras que las tutorías virtuales son las que más rechazo suscitan.

Este trabajo constituye una investigación preliminar sobre las concepciones, actitudes y sentimientos que muestran los estudiantes magisterio de Educación Infantil sobre la práctica de aula, con el triple objetivo de conocer la influencia del paso por las aulas durante el periodo de Practicum, los posibles cambios de metáfora en función del contenido abordado en el aula y los modelos docentes implícitos. Se realizó un estudio transversal con estudiantes de primer curso, tercero y cuarto. Se utilizó un cuestionario abierto sobre metáforas personales dirigido a futuros docentes. Las metáforas personales obtenidas fueron analizadas y clasificadas atendiendo al curso, a la formación previa y a las cuatro categorías utilizadas por Mellado et al. (2013). Se obtuvieron un total de 40 metáforas personales, 23 generales y 17 referentes a la educación científica. Los resultados muestran una menor influencia del periodo de Practicum que lo que apuntan otros trabajos publicados. Las mayores diferencias se encuentran entre los estudiantes de primer curso y los de tercero y cuarto. El contenido a abordar en el aula –ciencias– produce un cambio de metáfora personal.
Competencias Emocionales en el Proceso de Formación del Docente de Educación Infantil

Published: September 2023

El proceso de formación inicial del docente debe plantear el desarrollo de competencias emocionales, pues resultan cruciales para dotar de calidad la enseñanza del sistema educativo. De este modo, se deben articular acciones tendentes a facilitar el desarrollo de habilidades para que el docente tome consciencia de sí mismo, a la vez que maneje y reconozca tanto sus emociones y motivaciones como las de los otros. Esta investigación pretende evaluar el nivel de autorrealización y crecimiento personal de alumnado del Grado de Educación Infantil de la Universidad Católica de Murcia (n=183). Para ello, se ha utilizado una metodología descriptiva, llevándose a cabo la recogida de datos mediante la técnica de encuesta. El instrumento utilizado ha sido el “Cuestionario de Autoconcepto y Realización” (AURE) para así poder analizar contenidos considerados clave para el constructo “autorrealización” de la persona. Los participantes muestran niveles favorables en autorrealización y crecimiento personal, encontrando resultados más optimistas en el caso de las alumnas y entre aquellos que han accedido al Grado por vocación, influencia de un familiar vinculado a la docencia o para obtener cierta estabilidad laboral. Ello avala, pues, la importancia de desarrollar un programa “mindfulness” en el proceso de formación inicial del docente; su práctica persigue la felicidad, emociones positivas, resistencia física y mental y relaciones más satisfactorias.

Objetivo. Analizar las propiedades psicométricas del AAQ-II en población adulta ecuatoriana con tomas presenciales, aumentando la fiabilidad de la muestra. Método. En este estudio se evaluaron las propiedades psicométricas de la Acceptance and Action Questionnaire-II (AAQ-II) en población ecuatoriana. Participaron 450 personas entre 18 y 53 años, de las cuales un 46.7% fueron mujeres y un 53.3% hombres. Resultados. En el análisis factorial confirmatorio se encontró una estructura de tres dimensiones: evitación de recuerdos, evitación emocional y falta de autodominio. Un análisis de invarianza reveló que la escala es invariante entre hombres y mujeres. Se encontró que la escala presenta buena consistencia interna (α = .90). Se discute la validez de la AAQ-II como una herramienta para evaluar la evitación experiencial en población adulta ecuatoriana.

El alimento balanceado para tilapia está conformado principalmente por harina de pescado, harina de soya y otros productos proteicos de alto costo, convirtiendo a la Eisenia fetida en una alternativa para la sustitución proteica en la alimentación de estos peces. El presente trabajo de investigación tuvo como objetivo evaluar el efecto de la sustitución de materia seca por lombriz roja (Eisenia fetida) en la dieta de alevines de tilapia (Oreochromis aureus) sobre parámetros zootécnicos, índices corporales y composición química en peces llevados hasta la fase de engorde. El estudio se llevó a cabo en el Módulo Acuícola de la Estación Experimental Alfredo Volio Mata (EEAVM), entre mayo y septiembre de 2021. Se sembraron 8 alevines por pecera reversados hormonalmente (8 peceras en total) con un peso inicial promedio de 3,24 g ± 0,09 g. En la fase inicial, se utilizaron dos tratamientos, el tratamiento control (T0) y el tratamiento con un 50% de sustitución de alimento balanceado por la lombriz roja deshidratada (T1) en la materia seca. En la fase de engorde, se mantuvieron las mismas unidades experimentales, pero la alimentación fue de 100% de alimento balanceado. Se determinó el efecto de esta sustitución en la ganancia de peso, incremento en la longitud estándar y el ancho, tasa de crecimiento específico (TCE), tasa de conversión alimenticia (FCR), coeficiente térmico de crecimiento (CTC), eficiencia en el uso de proteína (PER), índice gonadosomático (IGS), índice hepatosomático (IHS), índice viscerosomático (IVS), relación cabeza/cuerpo y composición química final del tejido de los peces. En la ganancia de peso, incremento en la longitud estándar y el ancho, TCE, CTC, PER, IHS, IGS y composición química de los tejidos no se observaron diferencias significativas (p>0.05); en el FCR, IVS y relación cabeza/cuerpo sí se obtuvo diferencias significativas (p<0.05).
