Cross-modal iconicity and indexicality in the production of lexical sensory and emotional signs in Finnish Sign Language
Authors: Keränen Jarkko
Published: September 2023

In the present study, cross-modal (i.e., across sensory modalities such as smell and sound) iconicity (i.e., resemblance) and indexicality (i.e., contiguity) in lexical sensory and emotional signs in Finnish Sign Language will be considered from an articulatory perspective (i.e., the production of signs). Such cross-modal iconicity has not been extensively studied previously, so here, with the help of cognitive semiotics, I aim to carefully describe the cross-modal patterns observed across 118 signs, including 60 sensory signs and 58 emotional signs. The analysis is framed within the theoretical model of Semiotic Hierarchy, which entails a non-reductionist view of meaning. In addition, a pheno-methodological triangulation will be applied: phenomenology (first-person method), literature of phenomenological and semiotic descriptions (second-person perspective) and experimental findings (third-person perspective). The results of this analysis show that (a) 71 of the 118 sensory and emotional signs are cross-modally indexical, (b) only 10 of the 71 signs can be regarded as cross-modally iconic, (c) cross-modal iconicity is highly diagrammatic, (d) iconicity and indexicality are highly integrated, and (e) articulatory feedback matters in the formation of semiotic patterns. This study contributes to our understanding of cross-modal iconicity in signed languages, as well as studies in semiotic systems more generally.

Published: September 2023

Energy-saving tires have been developed by researchers in the industry in order to minimize hysteresis loss. In general, this is achieved by combining precipitated silica sourced from silica sand with a silane coupling agent. This strategic reaction serves to elevate the performance characteristics of tread tire, effectively enhancing their properties. Therefore, this research is aimed to investigate the utilization of commercially available biosilica compared to high dispersed (HD) silica, examining their potential as reinforcing agents in the composition of passenger tread tire compound. This compound was formulated using a blend of solution styrene-butadiene rubber (SSBR) and butadiene rubber (BR). A comprehensive analysis was conducted to assess the impact of varying ratios between biosilica and HD silica on the mechanical and dynamic properties of tread tire compound composed of SSBR and BR blend. The results showed that the incorporation of biosilica could effectively reduce the filler network resulting in better dispersion of biosilica in the SSBR/BR blend matrix. As a result, it improved wet grip (44%) and rolling resistance (26%) while maintaining abrasion resistance compared with HD silica in passenger tread tire compound. The application of biosilica as an eco-friendly reinforcement material exhibited its potential for elevating the performance of energy-efficient tread tire.
Effect of welding processes on ferrite content, microstructure and mechanical properties of super duplex stainless steel 2507 welds
Authors: Sekar Chandragiri Baskar , Koteswara Rao Sajja Rama , Vijayan Sundaravel , Boopathy Sadayan Rajendra
Published: September 2023

Super duplex stainless steel (SDSS) plates of 6 mm thickness have been welded using tungsten inert gas, activated tungsten inert gas, electron beam welding and friction stir welding processes. Among these, in the first two, melting and solidification of material occurs slowly whereas, it is faster in electron beam welding process and no melting occurs in friction stir welding. Macro and microstructural studies, hardness surveys, tensile tests and percentage of ferrite content were compared for all the welds. The ferrite–austenite phase balance is 50 % each, with electron beam weld metal at about 65 % ferrite. This showed the hardness of the weld metal and heat affected zones to be higher than base metal. The weldment joint efficiencies are more than 90 %. The fracture location is found to be in the weld metal for tungsten inert gas and activated tungsten inert gas weld, in the nugget for friction stir welds and in the base metal for electron beam welds. The ductility of electron beam weld joints is 32 % while it is around 20 % for the others. The preferred order while choosing the welding process should be activated tungsten inert gas welding, tungsten inert gas welding, electron beam welding, and friction stir welding.
“[...] naturam [...] divinam seu verum Deum [...] passum esse et mortuum”
Authors: Linde Gesche
Published: September 2023

The paper discusses the question to what extent one can speak of a genus tapeinoticum in Luther, or of a communication of the properties of nature to nature that is both direct and symmetrical. The thesis is that in the 1540 s Luther significantly modifies his earlier rejection of the idea of a passibility of divine nature as such by means of the distinctions between ‘concretum’ and ‘abstractum’ as well as between ‘relativum’ and ‘absolutum’. The boundary between passibility and impassibility does not run between the Son on the one hand and the Father and the Spirit on the other, but between the deus relativus and what might be called the ‘absolute-relative’ God.
Index of improvement of nonlinear single-channel signal detection systems under Gaussian noise
Authors: Tsevukh I. V. , Sakovich A. A. , Tsevukh V. I.
Published: September 2023

Detection of signals of moving targets against the background of an additive mixture of uncorrelated and correlated interference is one of the relevant and rather complex tasks solved in coherent-pulse radar systems. Correlated interference in the form of disturbing reflections from stationary or slowly moving objects significantly disrupts the regular operation of radar systems, which can lead to missing the target. The article presents a comparative analysis of the potential efficiency of two non-linear single-channel systems for useful signal detection operating under an additive mixture of uncorrelated and correlated Gaussian noise. To solve the task of analyzing the quality of detectors from the class of nonlinear structures, an improvement index was proposed, which is the signal/interference ratio at the output of the nonlinear system to the signal/interference ratio at its input, averaged over all possible radial velocities of the target. Numerical results of a comparative analysis of the potential effectiveness of the considered algorithms for various spectral-correlation parameters of interference are given. It was established that the potential efficiency of the algorithm developed by the author is higher than the efficiency of the algorithm implementing the well-known Hotelling statistics based on the improvement index and the parameters of the additive mixture of uncorrelated and correlated interference selected in this work.

Published: September 2023

In the maritime industry, it is common to load a vessel with bulk materials using conveyor scales. To determine the amount of cargo loaded into the hold of the vessel, it is necessary to simultaneously measure both the current weight on the weighing platform and the speed of the conveyor belt. In addition, the loading process is affected by both the heterogeneity of the bulk material and the uneven movement of the conveyor belt. Therefore, it is necessary to simultaneously and synchronously measure these parameters. The purpose of this work was to develop a device and an algorithm for its operation, which will improve the accuracy of determining the mass of cargo when loading a vessel.
Such a converter is located near the measuring sensor, and the frequency signal, the frequency of which is directly proportional to the output signal of the sensor along the line, is transmitted over a considerable distance without loss of information to the measuring device. The developed device for measuring the mass of bulk material using conveyor scales and the algorithm of its operation make it possible to simultaneously and continuously measure the current mass of the cargo and the speed of the conveyor belt, and, accordingly, the current mass of the cargo. The measurement accuracy was 0.25...0.5%. This device also allows you to get the characteristics of the weighing process to improve the mechanical conveyor designs of the scales.
Testing of the developed device was carried out on conveyor scales when loading the ship with mineral fertilizers. Testing showed that the developed device for obtaining tensometric information and the algorithm of its operation make it possible to control the process of loading a ship with bulk materials using conveyor scales with the planned accuracy, which, in turn, allows it to be used in computer systems for monitoring ship loading.
The developed device and the algorithm of its operation can improve the quality of measuring the mass of cargo and increase the accuracy of measurement, which is important from an economic point of view.
Uwagi na marginesie „obliczeniowej teorii zachowania” Alexa Pentlanda – programowej wizji społeczeństwa przyszłości
Authors:   Uniwersytet Łódzki, Ząbkowicz Anna
Published: September 2023

Purpose – Digital transformation offers new media of social communication. Starting from this point, the article asks whether this means a chance of survival or development of a new society, and by doing so it refers to ‘quantified theory of behaviour’ by Alex Pentland. Or, presumably, it opens enormous space for invigilation and social manipulation. Research method – This is a review of literature based on Alex Pentland’s publications, and referring to works of David Riesman, Jeremy Rifkin and Shoshana Zuboff. Results – Rather than on technical and systemic issues, the emphasis has been put on a fundamental transformation of social relations, which occurred in the developed countries prior to the digital transformation taking place at the turn of the 20th and 21st centuries. Originality / value / implications / recommendations – This transformation was discovered and described by outstanding authors like David Riesman, Jeremy Rifkin and Shoshana Zuboff. The review of their ideas concludes that digital culture makes existing institutional structures based on agreement weaker while making the inclination to instrumental and amoral re‑building of the collective order stronger.
The comparison of the impact of military and non-military government spending on GDP and consumption in Poland
Authors:   University of Lodz, Krajewski Piotr , Piłat Katarzyna ,   University of Lodz
Published: September 2023

Purpose – The purpose of the article is to compare the macroeconomic effects of military and non-military government spending on the Polish economy, which is particularly relevant in the context of the rapid rise in military spending after the outbreak of the war in Ukraine. Research method – The research is based on a new-Keynesian dynamic stochastic general equilibrium model estimated for the Polish economy. The model developed for the study takes into account differences between 3 types of government spending – military spending, non-military current spending and non-military investment. Results – On the one hand, the empirical results show that in the short and medium term, increasing military spending is a more effective method of stimulating GDP than rising non-military spending. On the other hand, the impulse response functions indicate that increasing non-military spending is a better tool for enhancing effective consumption. Originality / value / implications / recommendations – This is the first research exploring the macroeconomic effects of military spending in a CEE country, which is based on stochastic general equilibrium model accounting for heterogeneity of government spending. Assessing these effects at a time of unprecedented growth in military spending in Poland is an important added value of the study. The main implication of the research is to recommend increasing military spending to boost GDP, while rising non-military spending to stimulate effective consumption.

Purpose – The purpose of the research was to present the transfer of value in the business model of companies using crowdfunding in Poland based on the idea of sustainability in doing business. Research method – A survey was conducted on a group of 121 enterprises using crowdfunding. It used the Norton-Kaplan value map and the value flow model in accordance with the E3 concept and the idea of sustainable development Results – The conducted analyses have shown that the most important perspective of the value of crowdfunding is the financial and procedural perspective, while taking into account the crowdfunding model in conjunction with the concept of sustainable development, the most important are the economic and social dimensions. Originality / value / implications / recommendations – The added value of research is learning about the crowdfunding business model and creating value in CF for a company using the E3 model, taking into account economic, social and environmental values. Moreover, a new model was created based on the survey results, which is in line with the scientific discourse and thus bridges the research gap in this area. In addition, this model allows for the analysis of both the value offered and the value captured, not only for companies, but for each participant in accordance with the idea of sustainable development.

Purpose – Identifying changes in the volume of persons with tertiary education employed in science and technology, examining the relationship between tertiary education and employment in the high tech sector and its industries in the era of economy 4.0. Research method – Comparative analysis of statistical data, selected measures of descriptive statistics and Pearson’s r correlation method. Results – The research confirmed that the specificity of the industry determines the type of skills, and thus the level of education and the type of specialization of employees. Employment of workers with tertiary education grew faster than the total employment in the HT sector. People with tertiary education and employed in science and technology, as well as scientists and engineers were employed more often than people only with tertiary education. Originality / value / implications / recommendations – Despite the differing positions of researchers and practitioners, statistics indicate that tertiary education is still an important component of the competences of employees hired in the HT sector. Economy 4.0 requires highly skilled workers. It is essential to ensure a high level of educational quality and build stronger cooperation between science and business, so that educational offer is better suited to the needs of the labour market and reduces the problem of educational mismatch.

Active Learning Methodologies for Teaching Programming in Undergraduate Courses: A Systematic Mapping Study
Authors: Calderon Ivanilse , Silva Williamson , Feitosa Eduardo
Published: September 2023

Teaching programming is a complex process requiring learning to develop different skills. To minimize the challenges faced in the classroom, instructors have been adopting active methodologies in teaching computer programming. This article presents a Systematic Mapping Study (SMS) to identify and categorize the types of methodologies that instructors have adopted for teaching programming. We evaluated 3,850 papers published from 2000 to 2022. The results provide an overview and comprehensive view of active learning methodologies employed in teaching programming, technologies, programming languages, and the metrics used to observe student learning in this context. In the results, we identified thirty-seven different ALMs adopted by instructors. We realized that seventeen publications describe teaching approaches that combine more than one ALM, and the most reported methodologies in the studies are Flipped Classroom and Gamification-Based Learning. In addition, we are proposing an educational and collaborative tool called CollabProg, which summarizes the primary active learning methodologies identified in this SMS. CollabProg will assist instructors in selecting appropriate ALMs that align with their pedagogical requirements and teaching programming context.

Classification of SARS-CoV-2 Pediatric Hospitalizations: Delta vs Omicron Variant
Authors: Montarroyos Stephanie S. , Ladd Beatriz F. , Mestre Marcos , Cardenas Gabriel
Published: September 2023

OBJECTIVES

To classify COVID-19 pediatric hospitalizations based on reason for admission (“for COVID” or “with COVID”) and to compare disease severity and age between the delta and omicron variant predominant time frames.

METHODS

This was a retrospective study in patients aged ≤18 years who were hospitalized at a large, tertiary care pediatric hospital for COVID-19 from July 2021 to February 2022. Disease severity was determined based on length of stay, PICU admission, and Remdesivir receipt. A χ2 analysis and a Cochran–Mantel–Haenszel test were used to analyze relationships between presumed variant type with admission reason, disease severity, and age.

RESULTS

There were 492 patients included with more admissions during the omicron variant predominant time frame (n = 307). More patients were admitted “for COVID” during the delta variant predominant time frame compared with the omicron variant predominant time frame (P < .001) with interrater reliability testing indicating substantial agreement between reviewers. PICU admissions (P < .001), receipt of remdesivir (P < .001), and length of stay (P < .001) were greater during the delta variant predominant time frame. Hospitalizations “for COVID” were more common in patients aged <5 years during both the delta (odds ratio, 2.6; 95% confidence interval, 1.2–5.7) and omicron (odds ratio, 5.7; 95% confidence interval, 3.4–9.4) predominant time frames compared with older patients.

CONCLUSIONS

There was a higher proportion of symptomatic COVID-19 hospitalizations with higher disease severity during the delta variant predominance, indicating greater disease severity during earlier periods of the pandemic despite lower hospitalization rates.

El ordenamiento del territorio urbano cuenta con dos instrumentos de política para incidir en la ocupación del suelo y limitar el desarrollo de los mercados: la regulación en los usos del suelo y las restricciones a las alturas de edificación. En este documento se analiza cómo las restricciones de edificación especificadas para Bogotá en el marco del Plan Ordenamiento Territorial (POT) (Decreto 190 de 2004) y los procesos de urbanización de los municipios vecinos a la ciudad influyen sobre el bienestar urbano en la región. La metodología de análisis contempla la estimación un modelo de mínimos cuadrados ordinarios (MCO) en función del área total, el índice FAR (Floor Area Ratio), el cual mide el número de veces que representa el área construida sobre el área total, y la renta agrícola. Los resultados corroboran que las restricciones de edificación 2004 no han sido adecuadas en términos de condiciones de bienestar urbano, pues tuvo como resultado el crecimiento desordenado y disperso de los municipios.
La vivienda de interés social en el POT Bogotá Reverdece 2022-2035: reflexiones desde el hábitat y el “Derecho a la ciudad”
Authors: Caicedo Bedoya Angie Johanna , Murcia Pinilla María Fernanda , Parada Puentes Yair Alejandro
Published: September 2023

Existen múltiples retos frente a la vivienda de interés social (VIS) asociados a cómo, desde el sistema político y jurídico, se ha concebido el modelo de gestión habitacional en Colombia, lo cual tiene repercusiones directas en el quehacer del Distrito y en los instrumentos de ordenamiento como el Plan de Ordenamiento Territorial (POT). Asimismo, la mercantilización de la vivienda limita la construcción del hábitat en su integralidad como condición necesaria para relacionar la vivienda con la ciudad. En consecuencia, se presenta una dicotomía frente a esta relación en el marco de los derechos, pues el desarrollo normativo en materia de vivienda no contempla el hábitat como elemento fundamental para articular la VIS con su entorno inmediato, es decir, con la ciudad. Esta dicotomía se evidencia en el POT Bogotá Reverdece 2022-2035, ya que, más allá de generar unos mínimos de habitabilidad en términos métricos, no contrarresta fenómenos asociados a la concepción de la vivienda únicamente como una solución funcional o económica y, asimismo, impide contemplarla en clave de derechos. Este artículo de reflexión hace una revisión crítica de este POT a partir del derecho a la ciudad y el derecho a la vivienda. Para ello, toma como base la interpretación de fuentes secundarias sobre el derecho a la ciudad, el hábitat y la vivienda social a nivel nacional y distrital. También, analiza la prensa y las discusiones adelantadas por expertos y concejales sobre cómo se contempla la vivienda de interés social en el POT.

Authors: Aguilera-Núñez Ana-Rosalía
Published: September 2023

En este artículo se analiza la epidemia de viruela de 1796-1797 en la parroquia de Teotitlán del Valle y en la ciudad de Antequera, bajo un enfoque social y demográfico, el cual permitirá conocer, por un lado, las acciones de las autoridades civiles, eclesiásticas y médicas para frenar el avance de la epidemia y las reacciones de la población ante estas y, por el otro, los efectos demográficos de la viruela, principalmente, en las personas que nacieron después de la epidemia de 1780. El discurso de las autoridades y la población se analizó a partir de documentos de archivo, mientras que la información parroquial que da sustento al trabajo demográfico con el método agregativo. Se pudo observar que la intensidad de la epidemia fue menos mortífera, en relación con la precedente, debido probablemente a la aplicación de medidas como la variolización y el aislamiento de los enfermos, pero estas no fueron del todo aceptadas y se suscitaron ciertas “reacciones” en contra.
Representaciones de lo irrepresentable: el golpe de Estado en el cine chileno contemporáneo (2004-2020)
Authors: Santa Cruz-Grau José-Miguel , Kuhlmann Carolina
Published: September 2023

en este artículo nos proponemos problematizar cómo el cine y audiovisual chileno de ficción contemporáneo ha representado el golpe de Estado a la luz del concepto de acontecimiento. Siguiendo la teoría de las discontinuidades históricas de Alain Badiou, se entiende este como la gravedad existencial de lo irrepresentable. Si el golpe de Estado en Chile (1973) opera como esa singularidad que destruye los cimientos estructurales, transforma los sentidos de pasado y futuro, y fractura el devenir histórico. Las preguntas que rondan el texto son las siguientes: ¿es posible representar lo que se niega a la representación? ¿Cómo puede una organización limitada de imágenes contener tal densidad? Y a continuación, ¿qué es lo que se ha producido en este intento? Es en medio de este cuestionamiento que se indaga en las representaciones audiovisuales del golpe, como ensayo en medio de la imposibilidad, construimos la categoría de Esquema Básico de Representación (EBR). Este concepto ―que hace referencia a una estructura moldeable de elementos audiovisuales― habilita la revisión y análisis estético discursivo de un corpus de películas y series de televisión chilenas que tratan tal acontecimiento. La noción de EBR permite abordar desde las estructuras formales más básicas hasta los conceptos más complejos que organizan cada puesta en escena del golpe. Desde aquí, determinamos dos problemas estéticos predominantes en estas producciones: vacío y acumulación.
Perspectivas de análisis de las memorias del conflicto armado en Colombia (2005-2022)
Authors: Pineda-Rodríguez Sonia-Milena
Published: September 2023

desde hace un poco más de quince años Colombia ha vivido una ola de producción de memorias asociadas al conflicto armado. En ello ha contribuido la promulgación de leyes que legitimaron las voces de las víctimas, quienes por décadas lucharon porque sus pasados fueran significativos para la sociedad colombiana. Sin embargo, el número creciente de publicaciones, de actos públicos y de lugares promovidos por diversos actores sociales hace difícil comprender la totalidad de las memorias y de las reflexiones que hay sobre ellas. Después de una revisión sistemática de bibliografía y de sitios web, se propone una perspectiva de análisis que busca hacer inteligible el universo de dichas memorias. Se establecen tres categorías que sirven para definir algunas características generales: primero, los ámbitos de producción de las memorias, que responde a quiénes son sus emisores; segundo, las grandes áreas de trabajo, para establecer qué se dice sobre ellas; tercero, los vectores o vehículos con los cuales las memorias y sus reflexiones se materializan en la sociedad, es decir cómo se transmiten sus mensajes. Tal delimitación aporta en la construcción crítica de problemas de investigación sobre las memorias del conflicto armado ya que contribuye a visualizar un panorama general sobre su producción.

Controversias científicas
Authors: Pinto Manuela Fernández , Corral Cuartas Álvaro
Published: September 2023

Desde los inicios del filosofar y de las ciencias, el ejercicio de controvertir ha estado presente para dinamizar la emergencia de ideas, el reconocimiento de hechos y la formulación de métodos que los seres humanos han articulado con el propósito de entender las realidades que los rodean. Sin embargo, el estudio sistemático del desacuerdo en las ciencias como problema en sí mismo es de muy reciente data. Incluso la dimensión histórica de las controversias fue eclipsada por otras cuestiones aparentemente más relevantes en los procesos de transformación que ha tenido la filosofía de la ciencia en los últimos 150 años.

El objetivo principal de este artículo es analizar los estudios que respaldan la aprobación y el uso del BiDil, el primer medicamento aprobado para uso exclusivo en población afroamericana en EE. UU., así como la controversia que surgió alrededor de este. En particular, mostraré que la controversia sobre el BiDil no debe entenderse como una controversia puramente epistémica, sino como una controversia compleja en la que convergen aspectos tanto epistémicos como ético-sociales y comerciales. Entender cómo están interrelacionados estos aspectos y qué conocimiento podemos obtener dada la complejidad de estas interacciones resulta crucial para comprender la controversia sobre el BiDil, así como otras controversias científicas actuales.
Urban Road Network Serviceability Analysis Using Traffic Flow Profiles
Authors: Mallick Sasmita , T Gopikrishnan
Published: September 2023

Urban road networks are lifelines for cities in fulfilling the transportation needs of their inhabitants. The Patna Urban Agglomeration Area (PUAA) lacks properly planned roads; many of them have varying widths, with encroachments that reduce effective road width. A serviceability analysis is required through a traffic survey in order to create a traffic flow profile. This profile aids in performing time-based path, elevation, and serviceability analyses. In this study, traffic data were collected using cameras at vital road junctions and signals. A manual traffic survey was conducted at locations where active traffic was observed during peak hours. The road network of the study area was created using Google Maps, digitizing roads as lines and utilities as points. The traffic survey data, the road network, and the utilities were analyzed in the Network Analyst tool of the ArcGIS software. The analyses revealed suitable routing at underpass and overpass, as well as feasible paths during peak hours and locations with poor utility access. The analysis focused on the low-income group of people who depend on public transport and utilities and are the driving force of a developing economy. Suitable solutions are suggested to improve the existing road network.
A Study on the Performance and Emission Characteristics of a Diesel Engine Operated with Ternary Higher Alcohol Biofuel Blends
Authors: Ozgur Tayfun
Published: September 2023

This study focused experimentally on the evaluation of a higher alcohol biofuel utilization with diesel fuel in a compression ignition engine. To this effect, two different ternary higher alcohol biofuel blends with different percentages by volume were used, i.e., DA5 (85% diesel + 5% butanol +5% pentanol + 5% hexanol) and DA10 (70% diesel + 10% butanol + 10% pentanol + 10% hexanol). The performance and emission results were compared against reference standard diesel fuel. Experiments revealed the brake power (BP) values of the engine to be reduced due to the lower calorific value of the alcohols. In addition, this phenomenon led to increased levels of brake-specific fuel consumption (BSFC), which resulted in a higher fuel consumption to obtain unit power. Regarding emissions, carbon monoxide (CO) was reduced as a result of the additional oxygen content of alcohols, which triggered the more oxidized CO with oxygen. The results regarding unwanted nitrogen oxides (NOx) emissions were also attractive according to the alcohol utilized. Considerable reductions were obtained with alcohol mixtures when compared to diesel fuel, which can be explained by the reduced combustion temperatures in the cylinder, given the higher latent heat in the evaporation of alcohols.

Aiming to evaluate the useful life of biomaterials used in joint prostheses, this study performed different wear tests in stainless steel 316L, a biomaterial used in hip joint replacements. The tests were carried out in a dry medium, with the help of an equipment that was improved regarding some of its characteristics and allows conducting wear tests via the contact of two bodies, one of them being the biomaterial under study and the other one a sphere of a harder material. For the evaluation, a device was developed to change the rotation of the sphere, varying the angle it traveled and the frequency with which it did it. Once the improvements were made to the aforementioned equipment, tests were conducted which involved obtaining wear tracks in order to observe the surface morphology through scanning electron microscopy (SEM) and to measure the length and the width of the tracks, with which the biomaterial wear coefficient was obtained for each case studied. In these tests, the wear coefficient showed variations with respect to the sphere’s angle of travel.

This study estimated biometric attributes of individual trees from the automated measurement of tree height (THUV) by using images from unmanned aerial vehicles (UAVs). An experiment was carried out in a natural forest stand in the north of Mexico by using a DJI P4 multispectral equipment and regression analysis. The results show that total tree height (TH) is successfully estimated from UAV images, as the automated estimation of total height (THUV) reaches a R2 = 0,95 and a RMSE = 0,36 m. Consequently, THUV was statistically reliable to generate allometric equations (R2 > 0,57) regarding the canopy height model (CH), diameter at breast height (DBH), basal diameter (BD), above-ground biomass (AGB), volume (V), and carbon contents (C). It is concluded that the estimation of total height with UAVs is a viable option to improve efficiency in forest inventories. However, increased efforts towards the configuration of modern technologies and statistical algorithms are needed; future research challenges remain, particularly in the densest forests areas.

Published: September 2023

The main goal of this work is to provide insights on the combined influence of social media and innovation on industrial entrepreneurship in Mexico. To do this, we study the meaning of social networks and innovation in products and processes and their joint impact on industrial entrepreneurship by developing a structural equation model (sem) that shows the relationships between these three variables, using a hypothesis-based approach that demonstrates their close relationship in the creation of social value. The indices of goodness and fit were used to evaluate the sem, showing satisfactory results. One of the key findings of this study is the use of social networks, such as Facebook, WhatsApp, Instagram, and Twitter, among others, as digital marketing tools that allow increasing market share and achieving return on investment by diversifying products and services and signaling new business opportunities.
Lenguas Extranjeras en la FHCE de la Universidad de la República: usos y presencias
Authors: Carabelli Mari Patricia
Published: September 2023

Las lenguas extranjeras en la Universidad de la República son enseñadas primordialmente en el Centro de Lenguas Extranjeras que se encuentra ubicado en la Facultad de Humanidades y Ciencias de la Educación (FHCE). El objetivo de esta investigación es analizar cómo se da la relación entre lenguas extranjeras y producción de conocimiento en esta facultad. Para ello, se utiliza una metodología mixta basada en: i) el relevamiento del uso de lenguas extranjeras en las bibliografías recomendadas de todos los programas de las carreras de grado que se imparten en la FHCE; y, ii) entrevistas semiestructuradas a los docentes en régimen de dedicación total que recomiendan textos en lenguas distintas al español durante sus cursos. El análisis revela que, si bien se utilizan varios idiomas al recomendar la lectura de autores y autoras en las lenguas originales en que escriben y durante diferentes actividades académicas, existe un predominio de la lengua común, el español, en todas las áreas. Como conclusión, se resalta la percepción de la importancia del plurilingüismo tanto para fomentar la internacionalización de la institución como para promover cierta adquisición, circulación y producción de saberes.

This paper reports an exploratory, descriptive study on the emotions of content and language-integrated learning preservice teachers. The study, carried out in a Spanish university, aimed at analysing the internship experience of 19 preservice teachers in the context of a master’s degree in bilingual education (Spanish–English) for primary and secondary school teachers to determine the emotions experienced and the causative factors. The participants completed a questionnaire which showed that positive emotions were more frequent than negative ones. The variable causing such feelings included the subject taught, the sex of the teaching staff, previous experience, attitudes of educational centre tutors, and the students themselves. Therefore, the study highlights the affective dimension of teaching content and language-integrated learning.
Planning an Online Assessment Course for English Language Teachers in Latin America
Authors: Giraldo Frank , Yan Xun
Published: September 2023

In this article, we report the results of a study through which we collected English language teachers’ needs and wants to design an online language assessment course. Through a mixed-methods approach, we asked 20 teachers from four Latin American countries what they wanted to learn in the course. The teachers wanted a course in which they could address the challenges they faced in assessment; discuss and develop new ways to assess; and learn about authentic, valid, and ethical assessment. Therefore, the findings suggest that the teachers wanted a course that mixed theory, practice, and principles of assessment. Additionally, the course should address emerging topics in English language assessment, namely bilingual assessment and the assessment of learners with special educational needs.
