The antioxidant system plays an important role in the life of organisms. Its primary function is to protect against the damaging effects of excessive free radicals that lead to a state of oxidative stress. Enzymes of the insect antioxidant system may play a significant role in insecticide resistance. For insects, a number of antioxidant enzymes have been characterized, including catalase, superoxide dismutase, glutathione transferase and glutathione reductase. The role of catalase in this system is to break down hydrogen peroxide to form water and oxygen, thereby preventing membrane lipid peroxidation and cell damage. The aim of this study was to investigate catalase activity in adults of Musca domestica L. in field population. During homogenate production a comparative evaluation of the two-extraction media on catalase activity in adults of the laboratory strain of the house fly was also conducted. We found a statistically significant 1.12-fold increase in enzyme activity in adults of the field population compared to specimens of the laboratory strain of M. domestica. The catalase activity in homogenates prepared on 0.9% sodium chloride solution was statistically higher by 1.77-fold compared to the enzyme activity in homogenates on sodium phosphate buffer (pH 7.6) with Triton-X 100. The study of the insect antioxidant system may be useful in addressing the problem of insect resistance to insecticides, thus allowing the regulation of insect populations.
CYBER-PORTRAIT OF A RUSSIAN MUFTI. MEDIAMETRIC ANALYSIS
Authors:   Kuzeev Institute for Ethnological Studies, Ufa Scientific Centre, RAS, Yunusova A.B.
Published: September 2024

The article presents a collective digital portrait of the Russian mufti, made on the basis of an analysis of open media sources. The subject of the study is the active and passive digital traces of spiritual leaders in the Internet space and the backlash of the Internet space to the personality of the muftis. Based on open sources, a “Mufti” database has been created, which includes 100 current heads of Muslim spiritual administrations, muftiates, centers, councils, and representative offices of centralized Muslim organizations. Using quantitative methods, data was analyzed by attributes: age, religious and secular education, service in the armed forces, etc. Additionally, using the information and analytical system Brand Analytics, an analysis of media metrics of the “Mufti” entity was carried out – data was collected from social networks, news, messengers, telegram channels, blogs, videos, forums, etc. Both general messages about muftis and the accounts of 10 specific muftis included in the focus group were analyzed. During the analysis, the authors of the messages, their geographical location, word cloud, popularity, engagement, loyalty and sentiment were recorded. An analysis of Internet resources showed that 70% of Russian muftis do not have their own digital accounts and are present in cyberspace indirectly through the websites of spiritual administrations. The low activity of muftis on social networks, the presence of “sleeping” accounts and the lack of clear management of digital reputation are noticeable. A week-long monitoring of the network activity and cyber popularity of the muftis of a focus group of 10 people was carried out. The publics of the muftis, their statements and reactions to public events are reflected in the word cloud. Russian muftis are confidently included in the Top 100 Muslims of Russia, which is published by BUSINESS Online. The public activities of muftis as leaders of public opinion influence the state of the Muslim community in Russia, which determines the relevance of media metrics and analysis of the digital reputation of muftis. In general, the analysis demonstrates the capabilities of media metrics and open sources for studying Russian spiritual leaders.
Student Abstract: Emotion Detection with Physiological Signal Responses
Authors: Qu Boyi , Zhao Yi , Alsulaiman Mohammed
Published: September 2024

Affective computing using physiological signals is a key focus in research and industry. Wearable devices track health and emotions, with emerging applications for detecting risks like sexual or violent assaults by recognizing fear or panic. Multimodal systems incorporating video or audio signals can improve emotion classification. Biological factors like catecholamines, stress hormones released by the adrenal glands, may also help distinguish negative emotions. In a study of 21 women in a virtual reality setting, AI classified fear using physiological signals and catecholamine levels. While physiological data gave the best results, adding catecholamine variations did not improve accuracy.
Distributed leaderless formation maneuvers over directed graphs
Authors: Garanayak Chinmay , Mukherjee Dwaipayan
Published: September 2024

This paper investigates fully distributed leaderless formation maneuver control over a directed sensing topology. For formation maneuvering, generally, a leader-follower approach is adopted. Leaderless formation maneuvers have no designated leaders, unlike traditional approaches. Some of the leaderless approaches proposed recently in literature considered undirected sensing graphs, which means the agents need to sense in both directions. Also, in these approaches, although the control law implementation is distributed in nature, the design of the control laws requires a stabilizing diagonal matrix design, which makes the design of the control law centralized and knowledge of exact interaction among the agents is required for this. When an agent's sensing capabilities are limited, directed sensing topology becomes crucial. First, we propose control laws for leaderless formation maneuvers in $2$-D by manipulating the weights of complex-laplacian for single integrators with directed sensing graphs, and GAS (Global Asymptotic Stability) is established for it. In this approach, only translational, scale, and rotational formation maneuvers are possible. Then, we propose control laws for leaderless affine formation maneuvering for single integrators with directed sensing graphs for $2$-D and $3$-D, where translational, rotational, scale, and sheer formation maneuvering is possible. Also, an extension for the higher-order integrators is provided using a back-stepping-based design. Constant disturbances are also considered in the system dynamics. Finally, simulations are provided to validate the results.

Published: September 2024

Several studies have argued that bilingualism can confer adaptations to the human mind and brain. Among the possible moderators of such adaptations, language distance occupies a distinctly ambiguous role. While degree of similarity across lexical, morphosyntactic, and phonological representations has been argued to modulate the degree of recruitment of cognitive control mechanisms during bilingual processing, details of this modulation are un(der)specified, and, thus, largely unknown. Equally unclear is the directionality of the effect of language distance, with the literature providing support for two seemingly contradictory predictions. On the one hand, similar language bilinguals may exert more cognitive effort than distant language bilinguals, because monitoring language may become more effortful depending on how similar competing alternatives are. On the other hand, given that the pool of competing alternatives grows when there are fewer overlaps between languages, this widespread competition may require increased cognitive effort. The first hypothesis predicts that neurocognitive adaptations to bilingualism will be more pronounced in similar language bilinguals, while the second predicts this for distant language bilinguals. This systematic review and Bayesian analysis aim to decipher the role of language distance, assessing both behavioral and neurological evidence. We find robust evidence for a distance effect in bilingualism, but mixed evidence in relation to its directionality. We interpret the results through charting the extreme variability that exists across studies that can serve to test the impact of language distance, and we highlight the need for developing ecologically accepted metrics and definitions of what counts as similar in language processing.

Published: September 2024

Creative thinking is considered an important 21st century skill. Nevertheless, our understanding of how contextual factors such as socio-economic status and gender affect creativity is still limited – especially from an international perspective. In the current study, we thus examined the impact of gender and socio-economic status on creative thinking across 62 countries, using data from the 2022 Programme for International Student Assessment (PISA). Creative thinking, alongside mathematics and reading, was analyzed using a two-stage meta-analytic approach, integrating effect sizes from country-specific samples with a total sample size of N = 493,660. Our results revealed consistent gender disparities, with females outperforming males in creative thinking and reading, a trend robust across countries but with considerable variability. Gender disparities were less pronounced in the mathematical domain. Moreover, SES was found to be a strong predictor of creative thinking, mathematics, and reading, with higher SES associated with better performance across all domains. There was no substantial interaction effect between gender and SES for creative thinking and reading, suggesting that SES advantages are consistent across genders. Our analyses indicated substantial heterogeneity between countries, emphasizing the need for context-specific educational policies. These findings highlight the pervasive influence of gender and SES on fundamental educational outcomes and hence stress the necessity of tailored interventions to address these disparities around the globe.
Legitimation work in privatized criminal justice: Softening, shrinking, and signaling
Authors: Burkhardt Brett C
Published: September 2024

How do private companies justify taking on criminal justice functions? Building on writing on legitimacy and privatization, this article describes three rhetorical practices intended to increase the legitimacy of private companies carrying out criminal justice functions: softening (obscuring the use of force); shrinking (demonstrating deference to the state); and signaling (proclaiming alignment with pro-social values). The article demonstrates the analytic utility of these categories by considering public-facing Environmental, Social, and Governance (ESG) reports produced by one prominent company in the private corrections industry (CoreCivic). The conceptual typology of legitimation work brings together several dynamics that are common in privatized criminal justice and provides an analytic toolkit for future study. A discussion considers how researchers can use this typology to examine legitimation work by other private firms and industries that engage the criminal justice system.
Shape-locked Geometry Reduces Snapping Effects in Concentric Tube Robots
Authors:   Institute of Medical Device Technology, University of Stuttgart, Mayer J. , Steinbrenner B. T. , Pott P. P.
Published: September 2024

Concentric tube robots (CTRs) increase the dexterity of surgical instruments while maintaining small instrument diameters. The tip is bent by rotating and sliding the individual, nested tubes without the need for additional tendons. However, this design may become unstable under certain conditions due to the torsional wind- up created by rotating the tubes, which is at some point released by a sudden snapping movement. Several groups have demonstrated techniques to reduce snapping [1], [2], [3], [4]. Mostly, this was achieved through anisotropic cut-outs along the tubes. Still, some regions of the workspace remain difficult to access. Swaney et al. propose an alternative approach in which two tubes with an elliptical cross-section can be used at a locked relative tube rotation that would otherwise be unstable and not reachable [5]. However, the rotation angle was not intended to vary during use. This paper resumes the concept of shape-locked CTRs in order to provide discrete stable tube configurations throughout the entire workspace, including otherwise unstable regions. The tube cross-sections are designed as matching regular polygons with n edges to prevent unintended rotation. Unlike existing approaches, the tubes can still be rotated if the applied torque is high ◦ The aim of this work is to experimentally assess whether polygonal CTRs offer more uniform coverage of the workspace than annular CTRs.

Robot-assisted minimally invasive surgical approaches have grown in popularity among many medical fields such as general, gynecology, cardio-thoracic, ENT, and pediatric surgery [1]. As procedures strive to minimize trauma to surrounding tissues surgical tools must drasti- cally decrease in size. Consequently, researchers turn to alternative actuation methods to meet size constraints, resulting in scaling issues such as friction. Magnetic actuation presents a viable alternative to con- ventional cable-actuated tools (daVinci Surgical System) as forces and torques can be applied wirelessly through biological tissues [2]. Many magnetic robots at the mil- limeter scale such as forceps and mobile microrobots can only achieve a few millinewtons of force, smaller than required for surgical interventions [3]. These surgical tools require micro-transmission methods such as gear train systems, smart biomaterials, and twisted string actuators (TSA), to leverage the output of a magnetic system. TSAs are powerful, simple, compact, and have a high transmission ratio. Meaning that low-torque inputs are converted into large output-forces. Previous work implemented TSAs to augment the gripping force of a surgical gripper for neurosurgery applications, achieving a peak gripping force of 1.09 N using a 20 mT applied field [4]. The gripper, axially 55 mm long, required an extended length to enable the high output force. This work presents an improved forceps design 17 mm long by 3.5 mm wide (Fig. 1), that is a 3.25-fold reduction in length compared to the prior iteration while maintaining a similar blocking force of 1.05N. This improves the clinical feasibility of magnetically actuated surgical forceps as the tool can be articulated in confined spaces while generating enough force to manipulate tissue. In this paper, the tool design, operating principle, magnetic and TSA model, and mechanical testing are presented. Clinical feasibility is demonstrated through ex-vivo and in-vivo experimentation and the integration of a concentric tube robot (CTR) system.

Epilepsy affects more than 50 million people world- wide, afflicting patients with debilitating seizures. While antiepileptic drugs are available, 20-40% of patients remain medically refractory, leaving surgical interven- tion as the remaining option [1]. Hippocampal resec- tion is the gold standard surgical therapy, while laser interstitial thermal therapy (LITT) offers a minimally invasive alternative. Current LITT interventions involve delivery of thermal energy via a straight laser probe through a burr hole in the back of the skull under the guidance of magnetic resonance imaging (MRI). LITT has been associated with lower seizure freedom rates which we hypothesize is related to the use of straight line trajectories in a naturally curved structure. Our previous work proposed a percutaneous approach whereby a helically precurved needle is deployed through the foramen ovale to ablate along the hippocampal midline gripper capable of directly grasping needles. (c) De- maximizing tissue coverage [2]. This approach demands a safe, compact, and accurate actuation system capable of operating within the MRI scanner.

Colonoscopy is a powerful tool for the early detection of colorectal diseases. State-of-the-art colonoscopy, yet effective, often elicits discomfort among individuals, deterring some from undergoing this crucial diagnostic procedure. In addition, advancing the colonoscope up to the ileocecal valve demands a high level of expertise of the physician. The length of the colon requires the colonoscope to have a certain bending stiffness to resist buckling and looping during insertion, leading to substantial contact forces exerted on the colon wall. This contributes to patient discomfort and the risk of injuries or perforations of the colon. The general de- mand for increased patient-safety and simplified medical interventions, motivates the investigation of alternative approaches for the examination of the colon [1]. Expanding, Growing or Everting Robots are soft contin- uum robots whose locomotion principle is based on the eversion of a tubular vessel [2]. Locomotion is achieved by the growth of the robot at its tip, whereby the lumen of the robot is pressurized with gas while the robot’s base is fixed. No relative motion between robot body and the surrounding occurs, avoiding friction-related issues. The soft body of the robot can be shaped by its en- vironment, without compromising the ability to expand at the tip. These attributes recommend its application for colonoscopy. The lack of relative movement between robot and colon wall is expected to reduce intraoperative pain. Due to expansion at the tip, no counteractive forces are applied to the colon along the robot body. Furthermore, the working principle allows a design as a resource-efficient single-use device ensuring sterility. Similar approaches are described by Manoj et al. and Pore et al. [3], [4]. Manoj et al. use a motorized head unit to perform growth and retraction, while Pore et al. placed the actuation components in the robot base in a pressurized chamber. A soft robot for colonoscopy, whose growth is described as longitudinal expansion of a latex tube, stored in the robot’s tip, is described in [5]. The ColonoSight system addresses similar is- sues, however the working principle differs from the locomotion described above [6]. The application of expanding locomotion in colonoscopy rises challenges regarding maneuverability, the integration of camera and working channels, and the prevention of buckling during retraction. Aim of this work is to enable systematic investigation of the factors influencing the locomotion, such as ge- ometry and material of the tubular vessel as well as control strategies of gas pressure in combination with advancement/retraction speed. Focus is on a safe and reproducible locomotion of an expanding robot in the colon. A modular setup is described, that allows for simple testing of parameter configurations. In addition, a preliminary validation of the test rig design is described using a simplified course resembling the colons anatomy.

Published: September 2024

Robot-Assisted Surgical Systems (RASS) are increas- ingly widespread and researchers aim to introduce au- tomation during operations, supporting a progressive increase in the autonomy of RASS [1]. Given the sig- nificant successes obtained in other robotic applications [2], many works adopt Reinforcement Learning (RL) to support the RASS execution of different tasks, such as the manipulation of deformable tissues [3], [4], and the removal of debris or liquids during operations [5]. Generally, RL training requires numerous task repeti- tions, which are unsafe and impractical in real RASS. Fast and Flexible Surgical Reinforcement Learning (FF- SRL) addresses this by creating a realistic and com- putationally efficient simulator that runs entirely on a single GPU, eliminating bottlenecks associated with data transfer. The goal is to accelerate learning rates, mak- ing experimentation with RL in robotic surgery more accessible. The results indicate a significant reduction in training time for complex tasks, down to a couple of minutes compared to conventional CPU/GPU simula- tors. Such advancements are important in facilitating the development of autonomous and efficient RASS through RL techniques.

In the growing field of soft robotics, researchers are continuously exploring new ways to make robots move. A promising approach involves incorporating materials that react to stimuli like pH, temperature, light, and magnetic field into soft robots to achieve better control and manipulation [1]. Among these intelligent materials, light-responsive hydrogels have garnered significant attention [2]. One example is the copolymerization of PNIPAM with spiropyran, a photoresponsive molecule that transitions to a hydrophobic state upon illumination, leading to the shrinkage of the hydrogel [3]. This light-triggered response has the potential to enable non-invasive, cost-effective, and remotely controlled actuation. In the medical field, hydrogels that respond to light could be used to develop advanced drug delivery systems and novel actuation strategies for soft endoluminal robots, enhancing safety and efficacy in navigating the human body. While light-responsive hydrogels have been used to create microvalves for microfluidic devices [4], their translation to the macroscale remains largely unexplored. Here, we present a novel method for designing and fabricating photoresponsive valves embedded within soft channels for controlling soft robotic actuators. The characterization of the photoresponsive valves’ response time was investigated and showed promising results
Stiffness Investigations of A Soft Robot Manipulator for Affordable Endotracheal Intubation Devices
Authors:   Engineering Design and Production Research Group, Faculty of Mechanical and Aerospace Engineering, Institut Teknologi Bandung, Salman Muhammad Aldian , Virdyawan Vani
Published: September 2024

Endotracheal intubation (ETI) is a crucial procedure, performed approximately 15 million times annually in the USA alone [1]. To enhance the efficiency of ETI, especially in difficult circumstances, tools like stylets and introducers (bougies) are commonly utilized [2]. One of the most widely used aid tools known as an introducer, also referred to as “bougie“, is a malleable rod, mostly made of low-density polyethylene (LDPE) or polyvinyl chloride (PVC), is used as a guide to ‘railroad’ the ETT right into the laryngeal opening [3]. Existing introducers are mainly passive instruments, having to be pre-shaped only before the insertion. The lack of controllability, along with the property of the material that is stiffer than the tissue with which the device will interact, can lower the first-attempt intubation success rate [2], [4] and may also lead to a higher risk of injuring the patient [5]. In this work, we propose a design of a soft pneumatic continuum actuator to replace the structure located on the distal tip of an introducer as shown in the schematic in Fig. 1A. This means that the actuator should have sufficient rigidity to bend the rest of the shaft to which it is attached. In this work, we investigate a way to increase the stiffness of a soft robot manipulator by 1) adding an inextensible central rod with a higher bending stiffness than the silicone and 2) investigating the effect of pressurization in each chamber.

Published: September 2024

Transportation process is responsible for providing efficiency of moving products considering time, cost, and vehicle utilities through inbound and outbound logistics. Transportation disruptions such as congestion, delays, or cancellations can have a detrimental impact on the company. PT X uses trains to transport unpackaged cement in bulk from factory to port. PT X has not met the daily train delivery target due to train delays, inconsistency delivery frequency and ineffective schedule. Therefore, the quantity of shipment does not meet the expected target. In this study, optimization of train rescheduling was carried out to minimize total train delays. This optimization is expected to be able to create a new train schedule that meets the daily delivery target. The proposed model is formulated as and solved as Integer Linear Programming (ILP) problem by considering single-track railway constraints. Results show the optimal train schedules give a total delay of 26 minutes. Compared to the existing condition, train delays are reduced by 69.7% and provide a more effective schedule with consistent delivery frequency.

In Malaysia, the demand for beef outsprints its supply. This issue has led to an unstainable over-reliance on imports and consequently has brought to the issues of steep prices to end consumers. Part of the problem is a poor understanding of the beef buying preferences of consumers and the factors that shape the preferences. This study sought to determine the key factors influencing consumer buying preferences for beef among Malaysian, particularly examining the effects of price and quality. A cross-sectional survey of 384 beef consumers drawn from social media platforms was undertaken. Data was collected using a structured questionnaire and analyzed using SPSS. All factors were found to have a significant positive effect on beef buying preferences among consumers in Malaysia. It is recommended that firms in the beef industry consider these factors in their beef production and marketing

Published: September 2024

PT BINMED Ecomedika Industri (BINMED) is one of the companies engaged in the manufacture of medical devices in the form of special waste bins for sharps medical waste. Since starting to be marketed in 2019 until now, BINMED products have not reached the sales target. This is because conventional and/or non-standard safety boxes such as medical plastic bags, used bottles of mineral water in packaging, and jerry cans are still being used. In addition, BINMED products have just begun to be marketed in the Jabodetabek area using free trials and discounts. However, these two methods have not been able to attract the attention of potential buyers. Therefore, it is necessary to analyze the factors that influence prospective buyers to switch to using the BINMED safety box. The data collected were 72 samples using the purposive sampling technique to find the right respondents, namely prospective buyers working in the health sector. The variables used in this study include push effects (pricing, satisfaction, and trust), pull effects (attractive alternatives), and mooring effects (switching costs and subjective norms). Based on the results of data processing and analysis of research results, it was found that alternative interest had a significant effect on the intention to switch to the use of the safety box while the variables of pricing, satisfaction, trust, switching costs, subjective norms and the moderating effect of the mooring effects between push and pull effects and switching intentions did not affect switching intentions. The managerial implication that can be applied by the company is to promote on social media and cooperate with medical waste transport service providers who have collaborated with health facilities.

PRIORITY AREAS FOR SHAPING THE STRUCTURE OF CARGO FLOWS IN THE POST-WAR PERIOD
Authors: LАBUNETS I.Yu.
Published: September 2024

Topicality. With the blockade of Ukraine's ports by russia, maritime transport faces a rather difficult issue of finding new logistics routes, especially in the post-war period. There is also the question of new import and export partners that could replace russia. Before the full-scale invasion, russia was the main country that shaped export and import activities with Ukraine (metallurgy, ferrous metals, ores, slag and ash, etc.). Therefore, it is quite relevant to develop new logistics routes based on priority areas in the formation of cargo flows by Ukrainian maritime transport. Aim and tasks. The purpose of the study is to develop recommendations for the formation of an efficient and sustainable structure of cargo flows by using the transit potential of Ukrainian maritime transport through new logistics routes and Ukraine's participation in a large logistics network in the post-war period. Objectives: to analyse Ukraine's participation in transport corridors and networks; to develop new logistics routes based on previously identified strategically important cargoes; to analyse the possible inclusion of Ukraine in the newly created transport corridors. Materials and Methods. The article uses theoretical and empirical methods, namely, the analysis of the structure of cargo flows by partner countries of import/export activities, which made it possible to use the synthesis method to identify priority geographical areas and classify each individual type of cargo into a different direction. The method of deduction was used to formulate conclusions in the form of conceptual provisions for the formation of cargo flow by sea transport. The graphical method was used to summarise the material presented. Reserch results. While analysing strategically important cargoes, the author noticed a pattern of priority directions in the formation of cargo flows by sea. Since the full-scale invasion, partnerships with countries such as Turkey, China, European countries, African countries, Latin America, India, Korea and Japan have increased. For the most part, the author of the article considers it rational to use these countries when resuming regular logistics use of sea routes. In addition, while developing new possible logistics routes, a number of problems were identified, namely: the environmental component, mine danger, the state of port infrastructure, the legislative framework, insurance against military risks and destabilisation of freight rates. These problematic issues are planned to be addressed in the author's further research. Conclusion. On the basis of the previously identified strategically important cargoes, the author has formed and proposed new logistics directions and routes that will use the transit potential of Ukraine's maritime transport and allow us to become part of a large transport network (a link between the Nordic countries and Asia/Turkey; inclusion in the new Silk Road).

Authors: Moreno López William , Salazar Ching Federico
Published: September 2024

Introducción: Transcurrida una década desde la entrada en vigor del TLC suscrito entre Colombia y Estados Unidos, el silencio institucional y mediático contrasta con los bulliciosos anuncios de prosperidad que precedieron tal implementación. No abundan documentos que respondan ¿cómo ha evolucionado el comercio bilateral tras diez años de TLC? Para subsanar dicha falencia, este trabajo ofrece una evaluación de esa dinámica comercial. Metodología: El trabajo que se presenta en este texto comporta una revisión bibliográfica, la cual procede acorde con el carácter correlacional que deviene en descripción durante su desarrollo y permite dar cuenta del cumplimiento de los propósitos de la investigación: evaluar la dinámica comercial de ese TLC. Resultados: en este objetivo y luego de señalar, desde una perspectiva teórica de dependencia, el carácter impuesto y la condición asimétrica del Tratado se visualiza el comportamiento negativo registrado en la balanza comercial colombiana que verifica tal condición. Discusión: durante la última década Estados Unidos ha incrementado su capacidad de producción y diversificado sus exportaciones; mientras tanto, Colombia continua la producción y exportación de lo que ha hecho históricamente: bienes minero energéticos y materias primas. Conclusiones: El TLC perpetúa el intercambio desigual, propio de las relaciones económicas de dependencia.

Published: September 2024

Introducción: Nuestro trabajo muestra, una investigación cualitativa, a través de una experiencia educativa universitaria, analizando el estado de la inclusión y la equidad en España y México. Metodología: El objetivo fue determinar las barreras de aprendizaje y participación (BAP) y mejorar las competencias de estudiantes de Educación. Se desarrolló un análisis cualitativo documental de información inclusiva y equitativa de México y España y grupos de discusión de expertos. Los participantes fueron una muestra no aleatoria de 72 estudiantes de Educación de la universidad CEU Cardenal Herrera y Universidad de Monterrey (UDEM), y 12 docentes de Infantil y Primaria. Resultados: Existen diferencias leves entre las BAP para la inclusión y equidad en España y México, existiendo todavía en los centros educativos. Se determina que el nivel de formación didáctica y aplicación práctica en el aula no responde a las BAP, pero se trabaja por reducirlas por medio de nuevas políticas y recursos. Discusión: Se consigue los objetivos, mostrando cómo las BAP para la inclusión y equidad requieren de una respuesta global, que garantice las mismas oportunidades a todas las personas. Conclusiones: Se incluyen propuestas de mejora y se establece la necesidad de la pedagogía diferencial para la eliminación de las BAP.

Introducción: El artículo examina el uso de Instagram como herramienta para facilitar la comunicación de la información relevante sobre una asignatura presencial. Metodología: Participaron 93 estudiantes matriculados en una asignatura de Grado. Durante el cuatrimestre se realizaron 102 publicaciones de información, empleando de forma simultánea Instagram y el tablón de anuncios del Campus Virtual. Se analizó a través de qué herramienta se consultaban las publicaciones y también se aplicó un cuestionario para conocer la opinión sobre el uso de Instagram. Resultados: Instagram fue la herramienta más empleada para consultar la información sobre la asignatura y el alumnado valoró muy positivamente su utilización, destacando la facilidad que permitía para seguir la asignatura, las actividades prácticas, y el aumento de la motivación. Discusión: Aunque se encontraron algunas limitaciones y puede suponer un aumento en la carga de trabajo del profesorado, el uso de Instagram produjo efectos positivos y mejoró la comunicación sobre la asignatura, facilitando el proceso de enseñanza y aprendizaje, así como la motivación del alumnado.
Forma, espacio, luz y color: variables creativas introductoras del lenguaje y del proyecto arquitectónico
Authors: Viñas Limonchi Manuel
Published: September 2024

Introducción: En la década de los setenta, consolidadas las vanguardias arquitectónicas del siglo XX, teóricos como Fernando Chueca manifestaban la necesidad de afianzar un lenguaje arquitectónico que contribuyese al ancestral, pero vigente, promulgado en las edades clásicas. Advirtiendo esa armonía de la arquitectura con el lenguaje que Charles Jencks asociaba a la corriente posmoderna, esta investigación propone una revisión de diversos principios eminentemente gráficos que contribuyen a la praxis del proyecto ponderando el dialecto arquitectónico que formulan. Metodología: Se plantea un análisis de la sintaxis y la semántica, transcritas en morfología y relato, que deparan a la secuencia proyectual arquitectónica variables creativas como la forma y el espacio, así como —unificadas— la luz y su consecuencia, el color. Resultados: Una sistemática cuya repercusión brinda a la experiencia del usuario los patrones lineales y tecnológicos de Foster, los monumentales espacios verticales que erige Piano o las sensaciones cromáticas de la obra de Ito. Discusión: La propia, de carácter procedimental, que entablan las citadas variables con el paradigma arquitectónico que intervienen. Conclusiones: La actividad arquitectónica halla en su gramática, formulada a modo sintagmas o de variables creativas, un catalizador experimental que instruye y conecta el proceso constructivo con la percepción que la obra genera en el observador.
