Promoting sustainable consumption in Higher Education Institutions through integrative co-creative processes involving relevant stakeholders

The United Nations proposes to ensure a sustainable future for all through the Sustainable Development Goals, assigning a new role to each individual in all sectors of society. Higher Education Institutions are outstanding agents of change, introducing and implementing sustainability in a holistic way, connecting people, and including social and institutional considerations, with students being a key component of change. This study presents a co-creation model to incorporate sustainability in Higher Education Institutions, integrating all members of the university community with a multidisciplinary approach, seeking to address global needs with development tools for new products and services to facilitate the transition of consumers towards responsible consumption. The model aims to analyze the daily consumption pattern of the community at the university, to identify the degree of commitment to sustainability of its members, and to co-create in search of solutions related to responsible consumption and production. This is achieved through five phases of a model, each with specific tasks and objectives based on co-creation processes and tools. As a result, the model enables stakeholders to understand the needs of their community by actively participating within the five phases for developing more democratic solutions and social involvement regarding sustainability issues that can be solved through a co-creative process. The model combines the benefits through ethnographic techniques to discover habits, tools to involve participation, and co-creation to manage complex problems. Future research will focus on the application of the proposed model to more generalist contexts of society, addressing potential challenges due to vertical collaboration and barriers pre-established by society for the adoption of a sustainable lifestyle

Towards an automated analysis of video-microscopy images of fungal morphogenesis

7 páginas, 6 figuras.[EN] Fungal morphogenesis is an exciting field of cell biology and several mathematical models have been developed to describe it. These models require experimental evidences to be corroborated and, therefore, there is a continuous search for new microscopy and image analysis techniques. In this work, we have used a Canny-edge-detector based technique to automate the generation of hyphal profiles and calculation of morphogenetic parameters such as diameter, elongation rates and hyphoid fitness. The results show that the data obtained with this technique are similar to published data generated with manualbased tracing techniques and that have been carried out on the same species or genus. Thus, we show that application of edge detector-based technique to hyphal growth represents an efficient and accurate method to study hyphal morphogenesis. This represents the first step towards an automated analysis of videomicroscopy images of fungal morphogenesis.[ES] La morfogénesis de los hongos es un área de estudio de gran relevancia en la biología celular y en la que se han desarrollado varios modelos matemáticos. Los modelos matemáticos de procesos biológicos precisan de pruebas experimentales que apoyen y corroboren las predicciones teóricas y, por este motivo, existe una búsqueda continua de nuevas técnicas de microscopía y análisis de imágenes para su aplicación en el estudio del crecimiento celular. En este trabajo hemos utilizado una técnica basada en un detector de contornos llamado “Canny-edge-detector” con el objetivo de automatizar la generación de perfiles de hifas y el cálculo de parámetros morfogenéticos, tales como: el diámetro, la velocidad de elongación y el ajuste con el perfil hifoide, es decir, el perfil teórico de las hifas de los hongos. Los resultados obtenidos son similares a los datos publicados a partir de técnicas manuales de trazado de contornos, generados en la misma especie y género. De esta manera demostramos que la aplicación de esta técnica para el trazado de perfiles en hifas en crecimiento es un método eficaz y preciso para el estudio de la morfogénesis de hifas. Este trabajo representa el primer paso en la automatización de análisis de imágenes de video-microscopía de morfogénesis de hifas.This work was supported in part by the project Flora Micológica Ibérica V (REN2002-04068-C02-01GLO), Ministerio de Ciencia y Tecnología, Spain.

Handgrip strength and work limitations:A prospective cohort study of 70,820 adults aged 50 and older

The purpose of the study was to investigate the association between handgrip strength and the incidence of work limitations in European adults aged 50 and older. We conducted a prospective cohort study among adults aged 50 and older from 27 European countries and Israel. Data were collected from the Survey of Health, Ageing and Retirement in Europe (SHARE) waves 1, 2, 4, 5, 6, and 7. Handgrip strength was measured using a hand dynamometer (Smedley, S Dynamometer, TTM) and participants replied to questions about work limitations. Cox regression was conducted for statistical analyses. A total of 70,820 older adults (mean age 61 ± 7.7 years; 54.3 % women) were followed during a mean of 3.8 ± 2.9 years. The fully adjusted model showed that participants with low handgrip strength (<16 kg in women and <27 kg in men) had a significantly higher risk of work limitations compared with participants with normal values of handgrip strength (hazard ratio: 1.36; 95 % confidence interval: 1.28–1.44). Kaplan-Meier trajectories revealed that the survival probability to experience work limitations in the normal handgrip category was 20 % lower than in the low handgrip category in most of the follow-up period. We identified low level of handgrip strength as a risk factor for work limitations in adults aged 50 years or older. This could be used as an accessible measure to screen workers at risk of developing work limitations

Uses of Native Plant Species of a Communal Rangeland within ‘Sierra de Huautla’ Protected Area, México

Sustainability of communal rangelands has become a major concern at national and international levels because land use conflicts and associated social conflicts allows for over-utilization of selected species making a high pressure on them and given away their places to species with no use at all becoming lands degraded and unproductive. The objective of the study was to determine floristic composition and native plant uses by local peasants. The range surface is of 4262 ha, belongs to the communal land ‘El Limon’, in Tepalcingo, Morelos, Mexico, and it is within the Natural Reserve Area “Sierra de Huautla”. Native vegetation is mainly of deciduous shrubs, high temperatures year round and a rainy season of 4 months. Local peasants were surveyed on uses of the collected and previously identified plants. Number of species was 456, distributed in 266 and 76 botanical genders and families, respectively. Of the species identified 66, 22 and 12% had one, two or more than two uses according to local peasants. Among uses: 59% of the species were used as forage, 8% eatable, 7% firewood or ornamental, 6% medical herb, lumber or other use 4 %, construction material 3 % and for resin or handcraft 1%. The range showed a very high plant biodiversity, this feature allows for a high resiliency toward human activities

Exercise variables and pain threshold reporting for strength training protocols in people with haemophilia: a systematic review of clinical trials

Introduction: Although strength exercise is often prescribed for people with haemophilia (PWH), it remains unknown how exercise variables and pain thresholds are used to prescribe strength training in PWH. Aim: To analyse how strength exercise variables and pain thresholds have been used to prescribe strength training in PWH. Methods: A systematic search was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases from inception to 7 September 2022. Studies whose intervention included strengthening training in adults with haemophilia were included. Two independent reviewers were involved in study selection, data extraction and risk of bias assessment. Results: Eighteen studies were included. The least reported variables among the studies were: prophylactic factor coverage (11.1%), pain threshold/tolerability (5.6%), intensity (50%), total or partial range of motion (27.8%), time under tension (27.8%), attentional focus modality (0%), therapist experience in haemophilia (33.3%) and adherence assessment (50%). In contrast, weekly frequency (94.4%), duration (weeks) (100%), number of sets/repetitions (88.9%), repetitions to failure/not to failure (77.8%), types of contraction (77.8%), rest duration (55.6%), progression (55.6%), supervision (77.8%), exercise equipment (72.2%) and adverse event record (77.8%) had a higher percentage of reported (>50% of studies). Conclusion: Future research on strength training for PWH should improve information on pain threshold and other important variables such as prophylactic factor coverage, intensity, range of motion, time under tension, attentional focus modality, therapist experience in haemophilia and adherence assessment. This could improve clinical practice and comparison of different protocols

Augmented reality and Mathematics: a mediation proposal for the understanding of the function

Se presenta como base para la elaboración de una aplicación de realidad aumentada, un análisis descriptivo de las dificultades alrededor de las representaciones semióticas del objeto función (gráfico, tabular, algebraico y lenguaje natural), analizando la conversión y la transformación mediante una prueba con diez ítems. Los datos analizados pertenecen a 34 alumnos de un Bachillerato General Escolarizado (BGE) del Estado de Puebla y a 97 alumnos de un Bachillerato Universitario (BU) perteneciente a la Benemérita Universidad Autónoma de Puebla (BUAP). De los resultados obtenidos se puede observar poco dominio en la conversión de las representaciones gráficas a algebraicas. Es por ello por lo que la aplicación desarrollada pretende apoyar como andamiaje en esta representación semiótica del objeto función. La aplicación se realizó en Unity®. Se diseñó una secuencia didáctica de cinco momentos, los cuales incluían la intervención con realidad aumentada, se seleccionaron al azar 18 alumnos de los 97 alumnos del Bachiller Universitario que trabajaron en un curso extra de matemáticas. Se aplicó la secuencia didáctica con Realidad Aumentada, teniendo resultados favorables al tener una mejoría en el postestIt is presented as the basis for the development of an augmented reality application, a descriptive analysis of the difficulties around the semiotic representations of the function object (graphical, tabular, algebraic and natural language), analyzing the conversion and transformation through a test with ten items. The analyzed data belong to 34 students of a General School Baccalaureate (BGE) of the State of Puebla and 97 students of a University Baccalaureate (BU) belonging to the Benemérita Universidad Autónoma de Puebla (BUAP). From the results obtained, little mastery can be observed in the conversion of graphic representations to algebraic. That is why the application developed aims to support scaffolding in this semiotic representation of the function object. The application was made in Unity®. A fivemoment didactic sequence was designed, which included the intervention with augmented reality, 17 students were randomly selected from the 97 students of the University Bachelor who worked in an extra course of mathematics. The didactic sequence with augmented reality was applied, having favorable results by having an improvement in the posttes

Winter Forage Yield of Signal Grass (\u3cem\u3eBrachiaria brizantha \u3c/em\u3e(Hochst. Ex. A. Rich) R.D. Webster) at Different Cutting Frequency and N Fertilization

Signal grass (Brachiaria brizantha (Hochst. Ex. A. Rich) R.D. Webster) is widely grown in sub-humid tropical environments. In winter, shorter photoperiod and lower rainfall and temperatures reduce grass forage yield. Cutting frequency and N fertilization might reduce this negative effect (Whitehead, 1995; Pereira et al., 2014). The objective of the study was to determine winter forage yield total and by components of Signal grass under different cutting frequency and N fertilization

The Circumstellar Disk and Asymmetric outflow of the EX Lup Outburst System

We present Atacama Large Millimeter/submillimeter Array (ALMA) observations at 0.3 arcsec-resolution of EX Lup, the prototype of the EXor class of outbursting pre-main sequence stars. The circumstellar disk of EX Lup is resolved for the first time in 1.3mm continuum emission and in the $J$=2--1 spectral line of three isotopologues of CO. At the spatial resolution and sensitivity achieved, the compact dust continuum disk shows no indications of clumps, fragments, or asymmetries above 5-sigma level. Radiative transfer modeling constrains the characteristic radius of the dust disk to 23 au and a total dust mass of 1.0$\times$10$^{-4}$ M$_\odot$ (33 M_earth), similar to other EXor sources. The $^{13}$CO and C$^{18}$O line emission trace the disk rotation and are used to constrain the disk geometry, kinematics, and a total gas disk mass of 5.1$\times$10$^{-4}$ M$_\odot$. The $^{12}$CO emission extends out to a radius of 200 au and is asymmetric, with one side deviating from Keplerian rotation. We detect blue-shifted, $^{12}$CO arc-like emission located 0.8 arcsec to the north-west, and spatially disconnected from the disk emission. We interpret this extended structure as the brightened walls of a cavity excavated by an outflow, which are more commonly seen in FUor sources. Such outflows have also been seen in the borderline FU/EXor object V1647 Ori, but not towards EXor objects. Our detection provides evidence that the outflow phenomenon persists into the EXor phase, suggesting that FUor and EXor objects are a continuous population in which outflow activity declines with age, with transitional objects such as EX Lup and V1647 Ori
