Place-related neural activity in setting the stage for empathy
Authors: Vollberg Marius C. , O'Connor Brendan Bo , Vuilleumier Patrik , Sander David , Cikara Mina
Published: October 2023

What makes people experience varying degrees of empathy? Common accounts focus on interpersonal attributes, including victims’ group membership or social proximity to the observer. Here we demonstrate the contribution of imagining the scenes surrounding victims in driving empathy. Although imagination has been shown to moderate empathy, the relative importance of its components is unknown. Using fMRI (N = 48; right-handed, healthy, male adults), we separately identified activation maps preferentially associated with imagining places and persons, respectively. When participants imagined misfortunes happening to individuals in specific places, both the place and person maps jointly predicted affective empathy, and, less consistently, prosocial behavior. Place-preferential activation was at least as predictive as person-preferential activation. Results were robust to several group-, participant-, trial-level, and covariate-adjusted analyses. Moreover, place-preferential activation itself was strongly predicted by person liking, beyond place-related ratings. These findings are consistent with social affinity potentiating place imagination, which in turn increases empathy, above and beyond person imagination.
Music in Mood Regulation Brief scale (B-MMR): Italian version and insights on musical preferences, expertise, and reward experiences
Authors: Ansani Alessandro , Mallia Luca , Saarikallio Suvi
Published: October 2023

Music psychology has concentrated on how music listening is exploited for mood regulation. The Music in Mood Regulation Brief scale (B-MMR; Saarikallio, 2008) is a well-established measure to assess the types of strategies individuals adopt to regulate mood through music. The current study seeks to verify the psychometric dimensionality and reliability of the B-MMR in an Italian sample (N = 465). Furthermore, relationships of B-MMR with musical expertise, musical preferences, and music reward experiences, as measured by the Barcelona Music Reward Questionnaire (BMRQ), were investigated. Results showed that B-MMR maintained good internal reliability and identical dimensionality in the Italian sample. In addition, musical expertise was found to be associated with a stronger proclivity for the use of music for mood regulation. Furthermore, individuals with broader preferences and a tendency for harmonically and melodically complex music (e.g., classical, opera, and jazz) used music for regulatory purposes to a higher extent than those who favour recent genres (e.g., reggaeton and trap). Lastly, a Bayesian analysis of the psychometric network between B-MMR and BMRQ subcomponents revealed that many B-MMR strategies are linked with emotion evocation. Overall, this study developed an Italian version of the B-MMR and provided greater insights into the nuances related to the use of music for mood regulation.
Using Convolutional Neural Networks to Explore The Effect of Impaired Subitizing in Dyscalculia
Authors: Jay Rohan
Published: October 2023

Dyscalculia is a learning disability that impairs a person’s ability to solve mathematics problems. One of the issues many people with dyscalculia face is an impaired ability to subitize, which refers to the ability to look at a group of objects and recognize the number of objects without counting directly. In this article, we explore the ability of a convolutional neural network (CNN) to mimic the subitizing ability of both dyscalculic and non-dyscalculic persons. We look at first whether the model follows the same pattern in accuracy for both small and larger number of objects. Since people generally subitize smaller numbers of objects (e.g., two books, three dots, etc.) better than they subitize larger ones, the CNN should follow the same pattern. To model dyscalculia, we also simulate damaged neural connections (using dropout) and compare the behavior of the damaged network to behavioral data from dyscalculic children reported in [6]. Our methodology involved the creation of custom datasets and the introduction of dropout in the CNN to simulate potential neural deficits associated with dyscalculia. This research not only underscores the potential of CNNs in cognitive modeling but also paves the way for a deeper understanding of dyscalculia and its neural underpinnings.

Cordyceps militaris is one of the important medicinal fungi in traditional medicine. The fruiting body of C. militaris contains various bioactive compounds that have health-enhancing effects and support the treatment of various diseases. Therefore, this fungus is a potential source of medicinal materials for the development of healthcare products. The search for new strains of C. militaris with high yield, quality, and uniqueness is always of great interest. This study has provided new findings on some biological characteristics of an albino strain of C. militaris isolated in Vietnam. The albino strain of C. militaris SHBTQ was isolated and accurately identified based on morphological characteristics and the ITS (internal transcribed spacer) sequence of ribosomal DNA. The mycelial of C. militaris SHBTQ is white and remains stable for five successive generations. The most suitable carbon and nitrogen sources for the growth of the albino SHBTQ strain were sucrose and yeast extract, respectively. Notably, the SHBTQ strain is capable of forming fruiting bodies, with an average fresh fruiting body yield of 30 g/box, a biological efficiency of 12.2%, and a cordycepin content of 10.45 mg/g of dried fruiting bodies. This newly discovered strain offers great potential for further applications in production.

Terminalia catappa L. (so-called Bang in Vietnamese) is considered an important medicinal plant in folk medicine for the treatment of digestive disorders and other inflammatory conditions. This plant contains several medicinally essential components, especially the tannin group. This study evaluated a number of factors affecting tannin extraction from the leaves of sea almond tree with the help of response surface methodology (RSM). The factors used to evaluate are solvent concentration, solvent:material ratio (v/w) and soaking time (hours). Research results show that the highest total tannin content (TTC) is 1.54 mg GAE/g raw material, the optimal conditions are determined as follows: ethanol 54%, solvent:material ratio (S:MR) is 41:1 (v/w) and soaking time 2 hours. The experimental values (TTC=1.54±0.02 mg TAE/g raw material) show good agreement with the predicted value (TTC=1.54 mg TAE/g raw material). Experiments evaluating antibacterial activity show that the optimal extract of sea almond tree leaves has the ability to resist Vibrio parahaemolyticus bacteria. The results of this study could pave the way for the mass production of medicinal compounds containing tannins from sea almond tree leaves and improve the usage value of this popular plant.

Pulsed DC magnetron sputtering was employed to deposit gold onto polyethylene terephthalate (PET) film. The optical properties of the gold coating were evaluated through reflectance and transmittance measurements using a Jasco V-770/SLM-907 spectrophotometer. Spectral analysis provides information about the colour, impurities, surface quality, and coating thickness. In sputtering experiments with a circular target, the gold coating exhibits a relatively uniform colour in the area opposite the target, with a thickness (df) greater than 60 nm and a resistance lower than 6 Ω. The coating thickness gradually decreases away from the center, therefore affecting other physical properties, so it should be considered and used for calculations when coating on a large substrate. The fabricated gold coating passes tests for adhesion, friction resistance and resistance to cleaning agents, making it suitable for industrial and daily applications such as decoration or making electrodes for biosensors and electronic components.

Currently, aerobic biological methods are widely used for wastewater treatment. During the wastewater treatment process, air is forced by an air compressor into the biological treatment tank with high capacity, so, noise pollution often occurs during the system operation. This is affecting the health environment for workers, staff, and the surrounding population. Therefore, it is necessary to investigate and design a cover to reduce noise for the air compressor but not affect the operating efficiency of the device. The results in this study showed that after 30 minutes of continuous operation, the temperature around the air compressor increased by 2.5oC (from 29.5 to 32.0oC). The noise reduction is 4.0 dBA in case a polyurethane foam layer of 5 cm is used, and the noise reduction is 14.0 dBA if it is replaced with a mineral wool layer of 5 cm. The noise reduction is 17.0 dBA when combining the outer with a 5 cm polyurethane foam layer and the inner with a 5 cm mineral wool layer. Further, the noise reduction is reduced up to 24.0 dBA in case two layers of mineral wool (5 cm thick each) are used to form a homogeneous mass. Thus, using porous materials combined with mineral wool allows to reduce the noise level in accordance with the requirements of the QCVN 26:2010/BTNMT regulation (70 dBA).

In today's world, where digitalization is inevitable and necessary, it is extremely important to raise individuals with digital competence. For this reason, it is of great importance that textbooks, which are important instruments of the education environment, are prepared in a way that contributes to digital competence skills. The aim of the study carried out in this context is to determine to what extent digital competence is included in secondary school mathematics textbooks. Document analysis, one of the qualitative research methods, was used in the study. The documents of the study consist of eight secondary school mathematics textbooks belonging to different publishers and being taught in public schools in the 2022-2023 academic year. The documents determined within the scope of the research were analyzed with the content analysis technique using a technology-supported qualitative data analysis software. The analysis of the data was based on the content, learning areas, and DigComp 2.2 framework that included digital competence. The results obtained from the study show that textbooks generally do not pay much attention to DigComp dimensions, more digital competence is included in the textbooks of MoNE Publications compared to the textbooks of other publishers, but in general, the concept of digital competence, which has an important place in the curriculum, is not sufficiently included in secondary school mathematics textbooks. In line with the results obtained from the study, suggestions were made to textbook authors and researchers.

Las Colecciones Biológicas (CB) son repositorios de la biodiversidad consideradas como fuente primaria del conocimiento e información biológica en distintos niveles. Son utilizadas para la investigación científica, difusión/exhibición y docencia (Simmons & Muñoz 2005; Delgadillo y Góngora, 2009). Haciendo foco en este último punto, constituyen un recurso didáctico pertinente para el fortalecimiento de la calidad de los procesos educativos, tanto de manera física (en el aula) como virtual. Frente a la profunda crisis que actualmente atraviesa la biodiversidad (Cook et al. 2014), es imperante el desarrollo de dispositivos didácticos innovadores que fomenten un aprendizaje significativo del contenido y el uso de metodologías activas que aporten autonomía e independencia de los estudiantes, aun cuando no estén en el aula. En este sentido se las puede tomar como mediadoras pedagógicas, ya que facilitan el uso de la intuición y el razonamiento de los estudiantes, favorecen el diálogo entre ellos y el docente, además de un acercamiento comprensivo al material. Para que esto suceda, resulta clave el rol docente, puesto que son ellos quienes realizan un procesamiento didáctico de la información para acercarla a sus estudiantes, haciéndola más accesible, buscando el modo de visualizar los contenidos y tratarlos de la manera que crean más adecuada a través de distintas selecciones de medios y formatos que posibiliten el aprendizaje significativo (Fainholc, 2004). Por su parte, las Colecciones Biológicas Virtuales (CBV) tienen la ventaja de ser utilizadas en cualquier momento y lugar, permitiéndoles el acceso al material a múltiples estudiantes al mismo tiempo, sin causar deterioro  ni dependiendo de la accesibilidad al lugar físico en que se encuentra depositada la colección (Jofré Pasinetti et al., 2019).

Chemistry is generally viewed negatively by elementary school students. This problem in many cases is the result of the lack of applicability of methodologies that instigate the interest of students and guarantee the inclusion of all of them. Therefore, the work on screen aimed to report the development of an accessible and contextualized experimental class, in one of the 4th year of the Technical Course Integrated to the High School of Environmental Control of the Federal Institute of Education, Science and Technology of Paraíba - IFPB, João Campus Person. This action was intended to encourage the active participation of students through the didactic approaches addressed. Thus, through a qualitative and participatory research, the scholarship holders of the Tutorial Education Program of the Degree in Chemistry - PET Chemistry, from the aforementioned institution, developed an activity entitled "Experimental Chemistry Course for High School - CQEEM". This teaching intervention exposed a low-cost process to improve water quality, through the mucilage of the Xique-Xique cactos (Pilosocereus gounellei), a natural coagulant, for the treatment of cloudy water. This theme was chosen because it is a current and relevant subject to the experience of students of environmental control courses. The activity was divided into two parts: carrying out tests to confirm the real coagulante potential of the plant, and the development of the experimental procedure, by the group, from the separation of the samples of turbid water, the treatment of the water with the cactus mucilage, until the analysis of the turbidity decrease of the samples. In this process, the students presented satisfactory considerations regarding the activity, showing that this practice was fundamentally important for their technical training.
