Hilando generaciones y moda

El proyecto Hilando Generaciones y Moda tiene como objetivo principal fomentar el intercambio y la convivencia intergeneracional entre jóvenes del ITESO y adultos mayores que acuden al Centro Tapatío de Atención al Adulto Mayor, ubicado en Guadalajara, Jalisco. La problemática que se busca resolver con este proyecto es la falta de interacción y comunicación entre estas dos generaciones, lo que puede llevar a la desconexión y aislamiento social de los adultos mayores, así como a una falta de perspectiva y comprensión por parte de los jóvenes sobre las experiencias y desafíos que enfrentan las personas mayores. El proyecto busca romper con estas barreras mediante la realización de actividades que promuevan la convivencia y el aprendizaje mutuo entre ambas generaciones, permitiendo la integración social y emocional de los adultos mayores, así como el desarrollo de habilidades sociales y empáticas en los jóvenes. A través de la interacción y el diálogo entre ambas generaciones, se espera generar un ambiente de respeto y valoración hacia la sabiduría y experiencia de los adultos mayores, así como una comprensión más profunda de las realidades sociales y culturales que enfrentan. A lo largo del semestre hicimos distintas actividades relacionadas con moda, que fueron propuestas por nosotros mismos. Estos talleres pensados en los adultos mayores nos dejarían productos que reflejaran la identidad de cada adulto y con los que después haremos una exposición final. Nuestras primeras actividades con los adultos fueron hacer un collage y un esqueleto exquisito, en el que hablarían sobre ellos y podríamos conocerlos mejor. Después tuvimos un taller de joyería en el CETAM, donde los adultos crearon dijes personalizados. La siguiente actividad fue un taller de creación y personalización de playeras. Para esta, los adultos nos visitaron en el ITESO, donde compartimos desayuno, baile y creatividad con las pinturas para personalizar cada playera. Este semestre colaboramos con Andrés Moreno, stylist y creador de Vintage Ceremony. Andrés nos asesoró en nuestro camino para nuestra siguiente actividad: una sesión de fotos que buscó resaltar la identidad de cada adulto mayor. En esta sesión de fotos contamos con patrocinio de peinado y maquillaje. Nuestra última actividad será la exposición final, donde mostraremos los resultados de todas las actividades, como prendas hechas por los alumnos de moda (con telas diseñadas por ellos, inspiradas en los adultos).ITESO, A.C

CracidMex1: a comprehensive database of global occurrences of cracids (Aves, Galliformes) with distribution in Mexico

Cracids are among the most vulnerable groups of Neotropical birds. Almost half of the species of this family are included in a conservation risk category. Twelve taxa occur in Mexico, six of which are considered at risk at national level and two are globally endangered. Therefore, it is imperative that high quality, comprehensive, and high-resolution spatial data on the occurrence of these taxa are made available as a valuable tool in the process of defining appropriate management strategies for conservation at a local and global level. We constructed the CracidMex1 database by collating global records of all cracid taxa that occur in Mexico from available electronic databases, museum specimens, publications, “grey literature”, and unpublished records. We generated a database with 23,896 clean, validated, and standardized geographic records. Database quality control was an iterative process that commenced with the consolidation and elimination of duplicate records, followed by the geo-referencing of records when necessary, and their taxonomic and geographic validation using GIS tools and expert knowledge. We followed the geo-referencing protocol proposed by the Mexican National Commission for the Use and Conservation of Biodiversity. We could not estimate the geographic coordinates of 981 records due to inconsistencies or lack of sufficient information in the description of the locality.Given that current records for most of the taxa have some degree of distributional bias, with redundancies at different spatial scales, the CracidMex1 database has allowed us to detect areas where more sampling effort is required to have a better representation of the global spatial occurrence of these cracids. We also found that particular attention needs to be given to taxa identification in those areas where congeners or conspecifics co-occur in order to avoid taxonomic uncertainty. The construction of the CracidMex1 database represents the first comprehensive research effort to compile current, available global geographic records for a group of cracids. The database can now be improved by continuous revision and addition of new records. The CracidMex1 database will provide high quality input data that could be used to generate species distribution models, to assess temporal changes in species distributions, to identify priority areas for research and conservation, and in the definition of management strategies for this bird group. This compilation exercise could be replicated for other cracid groups or regions to attain a better knowledge of the global occurrences of the species in this vulnerable bird family

The High-Altitude water cherenkov (HAWC) observatory in México: The primary detector

The High-Altitude Water Cherenkov (HAWC) observatory is a second-generation continuously operated, wide field-of-view, TeV gamma-ray observatory. The HAWC observatory and its analysis techniques build on experience of the Milagro experiment in using ground-based water Cherenkov detectors for gamma-ray astronomy. HAWC is located on the Sierra Negra volcano in México at an elevation of 4100 meters above sea level. The completed HAWC observatory principal detector (HAWC) consists of 300 closely spaced water Cherenkov detectors, each equipped with four photomultiplier tubes to provide timing and charge information to reconstruct the extensive air shower energy and arrival direction. The HAWC observatory has been optimized to observe transient and steady emission from sources of gamma rays within an energy range from several hundred GeV to several hundred TeV. However, most of the air showers detected are initiated by cosmic rays, allowing studies of cosmic rays also to be performed. This paper describes the characteristics of the HAWC main array and its hardware.UCR::Vicerrectoría de Docencia::Ciencias Básicas::Facultad de Ciencias::Escuela de Físic

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Cosmological and astrophysical observations suggest that 85\% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions of particle physics. Assuming particle DM, this exotic form of matter cannot consist of Standard Model (SM) particles. Many models have been developed to attempt unraveling the nature of DM such as Weakly Interacting Massive Particles (WIMPs), the most favored particle candidates. WIMP annihilations and decay could produce SM particles which in turn hadronize and decay to give SM secondaries such as high energy $\gamma$ rays. In the framework of indirect DM search, observations of promising targets are used to search for signatures of DM annihilation. Among these, the dwarf spheroidal galaxies (dSphs) are commonly favored owing to their expected high DM content and negligible astrophysical background. In this work, we present the very first combination of 20 dSph observations, performed by the Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS collaborations in order to maximize the sensitivity of DM searches and improve the current results. We use a joint maximum likelihood approach combining each experiment's individual analysis to derive more constraining upper limits on the WIMP DM self-annihilation cross-section as a function of DM particle mass. We present new DM constraints over the widest mass range ever reported, extending from 5 GeV to 100 TeV thanks to the combination of these five different $\gamma$-ray instruments
