Citizen science and social innovation as citizen empowerment tools to address urban health challenges: The case of the urban health citizen laboratory in Barcelona, Spain.

Urban health faces significant challenges due to the rapid growth of cities and the concentration of population in urban settings that have a strong impact on people's health. The approach to characterize and address these challenges requires increased societal involvement and interdisciplinary solutions to ensure their effectiveness and democratic nature. With this purpose, it is necessary to explore methodologies for citizen participation that foster a critical understanding of the environment and promote their active role in generating scientific knowledge and change. This article describes the creation of a collaborative space for experimentation and learning that, through the intersection of citizen science and social innovation, aims to engage citizens in the research and diagnosis of their local environment, as well as in the design and implementation of local solutions, while raising awareness about the main challenges to urban health. Through a collaborative and participatory framework, the community identified relevant challenges to urban health they wanted to investigate, co-designed and developed the methodology for data collection and analysis, and ultimately, they devised, designed, and implemented innovative solutions based on the scientific evidence obtained. The framework and results of this project hold potential interest for the scientific community, facilities, institutions, and society by offering an innovative and participatory approach to addressing the present and future urban health challenges.

A Multiparameter Gas-Monitoring System Combining Functionalized and Non-Functionalized Microcantilevers.

The aim of the study is to develop a compact, robust and maintenance free gas concentration and humidity monitoring system for industrial use in the field of inert process gases. Our multiparameter gas-monitoring system prototype allows the simultaneous measurement of the fluid physical properties (density, viscosity) and water vapor content (at ppm level) under varying process conditions. This approach is enabled by the combination of functionalized and non-functionalized resonating microcantilevers in a single sensing platform. Density and viscosity measuring performance is evaluated over a wide range of gases, temperatures and pressures with non-functionalized microcantilevers. For the humidity measurement, microporous Y-type zeolite and mesoporous silica MCM48 are evaluated as sensing materials. An easily scalable functionalization method to high-throughput production is herein adopted. Experimental results with functionalized microcantilevers exposed to water vapor (at ppm level) indicate that frequency changes cannot be attributed to a mass effect alone, but also stiffness effects dependent on adsorption of water and working temperature must be considered. To support this hypothesis, the mechanical response of such microcantilevers has been modelled considering both effects and the simulated results validated by comparison against experimental data.

Polyglandular syndrome type 2 in a Mexican family and its association with human leukocyte antigen.

The evaluation of first-degree family members is very important to detect additional cases of polyglandular autoimmune syndrome type 2. The genetic evaluation of human leukocyte antigen (HLA) may be useful in the study of this syndrome. This study is the first report of an HLA study of this syndrome in a Mexican family.

Evaluación del modo lingüístico escribir con posibilidad de revisión y corrección del texto / Assessment of the linguistic mode of writing with the possibility of revision and correction of the text

En investigaciones sobre escritura se ha señalado que revisar y corregir los textos son aspectos fundamentales cuando se escribe. Se considera también que la manera en que escriben las personas puede estudiarse por medio de la habilitación lingüística, definida como la facilitación de un desempeño en modo lingüístico activo (señalar, escribir o hablar) como resultado de la exposición previa a un modo lingüístico reactivo (observar, leer o escuchar). Por ello, el objetivo de este estudio fue evaluar la exposición de estudiantes universitarios a los modos reactivos, sobre la habilitación lingüística del modo activo escribir y sobre la revisión y corrección cuando se les presenta de nueva cuenta el texto escrito. Los participantes, asignados a uno de tres grupos, primero escribieron un texto sobre el ciclo del agua, después fueron expuestos a uno de los tres modos lingüísticos reactivos, por último, se les presentó el texto escrito previamente sobre el ciclo del agua para su revisión y corrección. Los resultados mostraron puntajes de aciertos más altos para los grupos expuestos a los modos leer y escuchar, seguidos por el grupo donde debían observar. No se encontró corrección de los textos. Se discuten los resultados en relación con investigaciones de habilitación lingüística y con aspectos necesarios para la revisión y corrección de textos

In research about writing, it's been indicated that revision and correction of text are fundamental aspects of writing. It's also suggested that the way people write can be studied based on linguistic modes, defined as facilitation of the performance in an active linguistic mode (indicating, writing or talking) as a result of the previous exposure to a reactive linguistic mode (observing, reading or listening). The purpose of this study was to evaluate the effect of the exposure of undergraduates to different reactive modeson the linguistic mode of writing, as well as revision and correction when the written text is presented to them again. The participants, assigned to one of three groups, first wrote a text about the water cycle, then were exposed to one of three reactive linguistic modes, and last, were presented with the text that they had previously written about the water cycle to check and correct. The results show higher scoresin the groups exposed to the reading and listening modes, followed by those that were supposed to observe; no correction on the texts was found. The results are discussed in terms of linguistic modes research and the required aspects of revision and correction of texts interventions in mental and physical health issues based on the recognition of diversity and interculturality

Fluoride-bridged {Gd(III)3M(III)2} (M = Cr, Fe, Ga) molecular magnetic refrigerants.

The reaction of fac-[M(III)F3(Me3tacn)]⋅x H2O with Gd(NO3)3⋅5H2O affords a series of fluoride-bridged, trigonal bipyramidal {Gd(III)3M(III)2} (M = Cr (1), Fe (2), Ga (3)) complexes without signs of concomitant GdF3 formation, thereby demonstrating the applicability even of labile fluoride-complexes as precursors for 3d-4f systems. Molecular geometry enforces weak exchange interactions, which is rationalized computationally. This, in conjunction with a lightweight ligand sphere, gives rise to large magnetic entropy changes of 38.3 J kg(-1) K(-1) (1) and 33.1 J kg(-1) K(-1) (2) for the field change 7 T→0 T. Interestingly, the entropy change, and the magnetocaloric effect, are smaller in 2 than in 1 despite the larger spin ground state of the former secured by intramolecular Fe-Gd ferromagnetic interactions. This observation underlines the necessity of controlling not only the ground state but also close-lying excited states for successful design of molecular refrigerants.
