Anxiety, physical inactivity, as well as poor adherence to a good diet are some of the most frequent problems among the university population. This may be mainly due to the preoccupation with studies, exams and all the work assignments, ending in little time for culinary and physical activity. All of this leads to an increase in pathologies such as stress and anxiety, which causes students to create bad habits. The aim of this study was to relate stress and anxiety levels, as well as physical activity and adherence to the Mediterranean diet in a sample of university students. The focus is therefore on the differences between gender and academic performance. For this purpose, a cross-sectional, descriptive, comparative, descriptive design study was used, with a sample of 272 university participants who completed the PREDIMED test, the Beck anxiety inventory and an Ad Hoc sociodemographic questionnaire. The main results obtained are that the female sex suffers a higher rate of anxiety than the opposite sex. In addition, it is important to highlight that people who practice more physical activity have lower levels of anxiety, obtaining that 8 out of 10 students who practice physical activity have lower levels of anxiety.
La ansiedad, la inactividad física, así como la mala adherencia a una buena dieta son algunos de los problemas más frecuentes entre la población universitaria. Todo esto puede deberse principalmente a la preocupación por los estudios, los exámenes y todas las entregas de trabajos, finalizando en el poco tiempo para la actividad culinaria y física. Todo ello, concluye en el aumento de patologías como el estrés y la ansiedad, lo que hace que el estudiantado cree malos hábitos. El objetivo principal de este estudio fue relacionar los niveles de estrés y ansiedad, así como, la actividad física y la adherencia a la dieta mediterránea en una muestra de estudiantes universitarios. Enfocándose, por tanto, en las diferencias existentes entre el género y el rendimiento académico. Para ello, se ha utilizado un estudio de diseño comparativo, descriptivo y de corte transversal, contando con una muestra de 272 participantes universitarios, quienes completaron el test PREDIMED, el inventario de ansiedad de Beck, así como un cuestionario sociodemográfico Ad Hoc. Los principales resultados obtenidos son que, el sexo femenino padece un mayor índice de ansiedad que el sexo contrario. Además, es importante destacar que, las personas que practican mayor actividad física tienen menos niveles de ansiedad, obteniendo que, 8 de cada 10 estudiantes que practican actividad física, presentan niveles más bajos de ansiedad.

Body language and expression is a fundamental tool for working on emotions and non-verbal communication. Therefore, the aim of the present study was to analyse the opinions on body expression of students of the Early Childhood Education teacher training degree in Extremadura (Spain). The sample was formed by eighty-four last-year students. The results show that the students do not consider that they have received the necessary training to use the contents related to body expression in their classrooms. In addition, the respondents consider that the educational centres do not give sufficient importance to body expression, as a result of the lack of material, lack of conditioning of the educational facilities and lack of time in the pupils' daily workdays. Therefore, the number of training credits in the field of body expression should be improved and increased, as well as the continuous and specific training of active education professionals.
La Expresión Corporal es una herramienta fundamental para trabajar las emociones y la comunicación no verbal. Por ello, el objetivo del presente trabajo fue analizar las opiniones sobre la expresión corporal de estudiantes del grado de formación del profesorado de Educación Infantil de Extremadura (España). La muestra estuvo compuesta por ochenta y cuatro estudiantes de cuarto curso. Los resultados muestran que los alumnos no consideran que hayan recibido la formación necesaria para utilizar los contenidos relacionados con la expresión corporal en sus aulas. Además, los encuestados consideran que los centros educativos no dan la suficiente importancia a la expresión corporal, a consecuencia de la falta de material, falta de acondicionamiento de las instalaciones educativas y falta de tiempo en las jornadas diarias del alumnado. Por tanto, debe mejorarse y aumentarse el número de créditos de formación en el ámbito de expresión corporal, así como la formación continuada y específica de los profesionales de la educación en activo.

Published: November 2024

This qualitative study examines the linguistic and visual strategies employed in the placards of the Baloch Long March, a movement highlighting the struggles of marginalized Baloch communities. Applying Systemic Functional Linguistics (SFL) and Critical Discourse Analysis (CDA), this research seeks to uncover how language and visuals interact to convey messages of resistance and identity. The study addresses an identified gap in discourse analysis, focusing on how protest language and symbols are strategically used to challenge systemic oppression and amplify collective voices. Our findings reveal that Baloch Long March placards utilize assertive language, metaphorical expressions, and culturally resonant visuals that communicate the anguish of enforced disappearances and emphasize resilience and solidarity. SFL analysis highlights language's ideational and interpersonal functions in portraying oppression's personal and communal impact. At the same time, CDA offers insights into the power dynamics and ideological structures that these messages critique. Nonverbal elements, including colour symbolism and visual metaphors, strengthen the emotional appeal and accessibility of the messages, enhancing their impact on audiences. This study contributes to discourse and communication research by illustrating how integrated linguistic and visual elements in protest placards foster accessibility and encourage collective mobilisation. In addition, this research underscores the power of language and imagery in shaping social narratives.

Non-anthropocentrism as Participation alongside Perspective: Indigenous Philosophers and Dynamics of Inter-species Kinship
Authors: Wehrheim Kat 
Published: November 2024

Contemporary Western alternatives to anthropocentrism – such as sentientism or biocentrism – rely on the scope of human knowledge exceeding its realistic limitations. As a corollary, although these models continue to be helpful in discerning ethical conduct, additional resources are going to be required. Initially arguing from within a representationalist paradigm, this paper shows that besides our inability reliably to assess the capacities of non-human species, we have also yet to learn what other factors, besides capacity, may be relevant to a non-human’s moral considerability. Subsequently arguing from within a participationalist paradigm, this paper shows that we cannot preconceive all we may be in the process of co-creating. This leaves any model grounded solely in the already existing open to finding itself incapable of relating to the new. It is in the co-creativity of the latter that a potential starting point for resolution begins to emerge: drawing upon Indigenous conceptions of performative knowledge processes in non-objectifying relationality, this paper shows dynamics of inter-species kinship, at times partially traceable through evolutionary relationship, to be a source of non-propositional learning relevant to ethical concerns.

Seaweed and seaweed-based products are gaining global attention due to their health-benefiting properties. For the last three decades, seaweeds have been used as nutraceutical food, as they provide dietary benefits. It offers a rich source of nutrients, including minerals, vitamins, and fibre, while also possessing unique functional properties such as water and oil absorption. Due to their functional characteristics, the incorporation of seaweed into bakery products is becoming a novel strategy to develop nutritionally enriched value-added products. Cookies are one of the most popular bakery products, with high consumer preference. The incorporation of seaweed offers a promising avenue for enhancing the nutritional value of cookies. It improves the physical, sensorial, and nutritional properties of cookies. This review seeks to explore the significance of seaweed consumption, the development of value-added cookies incorporating seaweed, and the impact of seaweed on the overall quality of cookies.

Abstract

Objectives
Worksite-based programs present a simple and effective approach to facilitate weight reduction in employees. Despite the importance of 1-year weight loss maintenance, studies have generally focused on the short-term effects of weight reduction programs. In addition, little is known about the long-term weight maintenance outcomes in Asian populations. We examined the long-term maintenance effects of a worksite-based weight reduction program among Japanese men with cardiovascular risk factors.

Methods
The study sample comprised 58 overweight men with cardiovascular risk factors who had voluntarily participated in a randomized crossover trial involving a 3-month weight reduction program. Participants were followed up for 1 year after the trial concluded, and both groups were merged for the analysis. We compared the changes in body weight before the post-trial follow-up and after 12 months to examine the long-term maintenance effects of the program. Changes in other cardiovascular risk factors (eg, waist circumference, blood pressure, lipid measures, and diabetes-related measures) were also examined.

Results
Both groups of study participants achieved weight loss during the weight reduction program. Total 53 participants (91.4%) completed the 12-month post-trial follow-up. There were no significant changes in mean body weight (mean: −0.11, 95% confidence interval: −0.7-0.49 kg) and other cardiovascular risk factors between the beginning and end of the follow-up period.

Conclusions
This study showed that the worksite-based weight reduction program not only enabled short-term weight loss, but that the participants were able to successfully maintain their weight for 1 year after the program without any supplementary interventions.

Abstract
Fish kill investigations are critical to understanding threats to aquatic ecosystems and can serve as a measure of environmental disruption as well as an early indicator of emerging disease. The goal of this study was to analyze historical data related to such events among wild fish populations in Minnesota in order to assess the quality and completeness of the data and potential trends in fish kills. After excluding events with incomplete data (e.g., in which the location was not reported), we analyzed 225 unique fish kills from 2003 to 2013 that were recorded in two Minnesota Department of Natural Resources databases. The most reported fish kills occurred during 2007 (n =41) and during the month of June (n =81) across all years. Centrarchid species were present in the most fish kills (138), followed by cyprinid and ictalurid species, which were present in 53 and 40 events, respectively. Environmental factors were the most common cause of death reported. Models of environmental factors revealed that the maximum nighttime land surface temperature was the most critical factor in fish mortality, followed by changes in primary productivity and human disturbances. During the course of this study, data gaps were identified, including underreporting, inconsistent investigation, and the lack of definitive diagnoses, making interpretation of our results challenging. Even so, understanding these historical trends and data gaps can be useful in generating hypotheses and advancing data collection systems for investigating future fish kills. Our study is a primer investigation of fish kills providing information on the plausible areas, seasons, and fish groups at risk that can guide active environmental monitoring and epidemiological surveillance of fishes.

AbstractMetallic glass (MG), with the superiorities of unique disordered atomic structure and intrinsic chemical heterogeneity, is a new promising and competitive member in the family of environmental catalysts. However, what is at stake for MG catalysts is that their high catalytic efficiency is always accompanied by low stability and the disordered atomic configurations, as well as the structural evolution, related to catalytic performance, which raises a primary obstacle for their widespread applications. Herein, a non‐noble and multicomponent Fe83Si2B11P3C1 MG catalyst that presents a fascinating catalytic efficiency while maintaining remarkable stability for wastewater remediation is developed. Results indicate that the excellent efficiency of the MG catalysts is ascribed to a unique atomic coordination that causes an electronic delocalization with an enhanced electron transfer. More importantly, the in situ self‐reconstructed hierarchical gradient structure, which comprises a top porous sponge layer and a thin amorphous oxide interfacial layer encapsulating the MG surface, provides matrix protection together with high permeability and more active sites. This work uncovers a new strategy for designing high‐performance non‐noble metallic catalysts with respect to structural evolution and alteration of electronic properties, establishing a solid foundation in widespread catalytic applications.

AbstractMetasurfaces open up unprecedented potential for wave engineering using subwavelength sheets. However, a severe limitation of current acoustic metasurfaces is their poor reconfigurability to achieve distinct functions on demand. Here a programmable acoustic metasurface that contains an array of tunable subwavelength unit cells to break the limitation and realize versatile two‐dimensional wave manipulation functions is reported. Each unit cell of the metasurface is composed of a straight channel and five shunted Helmholtz resonators, whose effective mass can be tuned by a robust fluidic system. The phase and amplitude of acoustic waves transmitting through each unit cell can be modulated dynamically and continuously. Based on such mechanism, the metasurface is able to achieve versatile wave manipulation functions, by engineering the phase and amplitude of transmission waves in the subwavelength scale. Through acoustic field scanning experiments, multiple wave manipulation functions, including steering acoustic waves, engineering acoustic beams, and switching on/off acoustic energy flow by using one design of metasurface are visually demonstrated. This work extends the metasurface research and holds great potential for a wide range of applications including acoustic imaging, communication, levitation, and tweezers.

AbstractIon migration and phase segregation, in mixed‐cation/anion perovskite materials, raises a bottleneck for its stability improvement in solar cells operation. Here, the synergetic effect of electric field and illumination on the phase segregation of Cs0.05FA0.80MA0.15Pb(I0.85Br0.15)3 (CsFAMA) perovskite is demonstrated. CsFAMA perovskite with a CsPbBr3‐clusters passivated structure is realized, in which CsPbBr3‐clusters are located at the surface/interface of CsFAMA grains. This structure is realized by introducing a CsPbBr3 colloidal solution into the CsFAMA precursor. It is found that CsPbBr3 passivation greatly suppresses phase segregation in CsFAMA perovskite. The resultant passivated CsFAMA also exhibits a longer photoluminescence lifetime due to reduced defect state densities, produces highly efficient TiO2‐based planar solar cells with 20.6% power conversion efficiency and 1.195 V open‐circuit voltage. The optimized devices do not suffer from a fast burn‐in degradation and retain 90% of their initial performance at maximum power under one‐sun illumination at 25 °C (65 °C) exceeding 500 h (100 h) of continuous operation. This result represents the most stable output among CsFAMA solar cells in a planar structure with Spiro‐OMeTAD.

AbstractDespite its revolutionary success in hematological malignancies, chimeric antigen receptor T (CAR‐T) cell therapy faces disappointing clinical results in solid tumors. The poor efficacy has been partially attributed to the lack of understanding in how CAR‐T cells function in a solid tumor microenvironment. Hypoxia plays a critical role in cancer progression and immune editing, which potentially results in solid tumors escaping immunosurveillance and CAR‐T cell‐mediated cytotoxicity. Mechanistic studies of CAR‐T cell biology in a physiological environment has been limited by the complexity of tumor‐immune interactions in clinical and animal models, as well as by a lack of reliable in vitro models. A microdevice platform that recapitulates a 3D tumor section with a gradient of oxygen and integrates fluidic channels surrounding the tumor for CAR‐T cell delivery is engineered. The design allows for the evaluation of CAR‐T cell cytotoxicity and infiltration in the heterogeneous oxygen landscape of in vivo solid tumors at a previously unachievable scale in vitro.

AbstractElectrochemical therapy (EChT), by inserting electrodes directly into tumors to kill cancer cells under direct current (DC), is clinically used in several countries. In EChT, the drastic pH variation nearby the inserted electrodes is the main cause of tumor damage. However, its limited effective area and complex electrode configuration have hindered the clinical application of EChT in treating diverse tumor types. Herein, a conceptually new electric cancer treatment approach is presented through an electro‐driven catalytic reaction with platinum nanoparticles (PtNPs) under a square‐wave alternating current (AC). The electric current triggers a reaction between water molecules and chloride ions on the surface of the PtNPs, generating cytotoxic hydroxyl radicals. Such a mechanism, called electrodynamic therapy (EDT), enables effective killing of cancer cells within the whole electric field, in contrast to EChT, which is limited to areas nearby electrodes. Remarkable tumor destruction efficacy is further demonstrated in this in vivo EDT treatment with PtNPs. Therefore, this study presents a new type of cancer therapy strategy with a tumor‐killing mechanism different from existing methods, using nanoparticles with electrocatalytic functions. This EDT method appears to be minimally invasive, and is able to offer homogeneous killing effects to the entire tumor with a relatively large size.
