Risk of Food Insecurity Reflects Health Status in Adult Relatives of PreK Children – Data from the STEPS Snap-Ed Research Study
Background: Past research shows a correlation between household food insecurity and chronic medical conditions such as diabetes in the general U.S. population as well as metabolic syndrome-related cardiometabolic markers in Hispanic/Latino youth. Furthermore, minority status, including Hispanic/Latino identity, shows an association with low food security and diabetes. The Hunger Vital Sign (HVS) is a validated screener designed to assess risk of food insecurity within households. This study analyzes associated factors related to the screener’s 2 questions, specifically targeting PreK 4-year-old children and their household relatives. The first question assesses concern about food running out before obtaining more due to financial constraints, while the second question evaluates instances when food did not last and there was insufficient money to purchase more.
Methods: The participating preschools were primarily Hispanic/Latino and nested within schools and school districts. Data were collected through household questionnaires. The frequency of food insecurity (FI) risk was measured as an ordinal variable (never, sometimes, often) and dichotomized (never vs sometimes + often). Agreement between questions was assessed using the kappa coefficient. Mixed models were employed to predict the risk of children’s BMI and the risk of relatives developing chronic disease, adjusting for age and sex.
Results: The study included 828 families, with 74% reporting never experiencing food insecurity, 22% sometimes, and 4% often. The agreement between the 2 survey questions was substantial (kappa 0.80, p \u3c 0.001). Probability of FI decreased as income level and education level of parents increased. No significant associations were found between FI and children’s age, BMI, height, or the ratio of children to adults in the household. However, a positive screen using the HVS correlated with hypertension and/or diabetes in the family.
Conclusion: The HVS screens for food insecurity risk and is associated with health issues in adults rather than children\u27s body weight or height. Responses to the survey’s 2 questions can provide insights into the overall health status of a household, emphasizing the intricate relationship between food insecurity, malnutrition, and various health outcomes. The presented results support planning and resource allocation strategies to reduce food insecurity in the Hispanic/Latino population
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
Demographic History of Indigenous Populations in Mesoamerica Based on mtDNA Sequence Data
The genetic characterization of Native American groups provides insights into their history and demographic events. We sequenced the mitochondrial D-loop region (control region) of 520 samples from eight Mexican indigenous groups. In addition to an analysis of the genetic diversity, structure and genetic relationship between 28 Native American populations, we applied Bayesian skyline methodology for a deeper insight into the history of Mesoamerica. AMOVA tests applying cultural, linguistic and geographic criteria were performed. MDS plots showed a central cluster of Oaxaca and Maya populations, whereas those from the North and West were located on the periphery. Demographic reconstruction indicates higher values of the effective number of breeding females (Nef) in Central Mesoamerica during the Preclassic period, whereas this pattern moves toward the Classic period for groups in the North and West. Conversely, Nef minimum values are distributed either in the Lithic period (i.e. founder effects) or in recent periods (i.e. population declines). The Mesomerican regions showed differences in population fluctuation as indicated by the maximum Inter-Generational Rate (IGRmax): i) Center-South from the lithic period until the Preclassic; ii) West from the beginning of the Preclassic period until early Classic; iii) North characterized by a wide range of temporal variation from the Lithic to the Preclassic. Our findings are consistent with the genetic variations observed between central, South and Southeast Mesoamerica and the North-West region that are related to differences in genetic drift, structure, and temporal survival strategies (agriculture versus hunter-gathering, respectively). Interestingly, although the European contact had a major negative demographic impact, we detect a previous decline in Mesoamerica that had begun a few hundred years before
The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra
This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17)

The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys
The James Webb Space Telescope Mission
Twenty-six years ago a small committee report, building on earlier studies,
expounded a compelling and poetic vision for the future of astronomy, calling
for an infrared-optimized space telescope with an aperture of at least .
With the support of their governments in the US, Europe, and Canada, 20,000
people realized that vision as the James Webb Space Telescope. A
generation of astronomers will celebrate their accomplishments for the life of
the mission, potentially as long as 20 years, and beyond. This report and the
scientific discoveries that follow are extended thank-you notes to the 20,000
team members. The telescope is working perfectly, with much better image
quality than expected. In this and accompanying papers, we give a brief
history, describe the observatory, outline its objectives and current observing
program, and discuss the inventions and people who made it possible. We cite
detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space

Diseño estratégico de vanguardia
La integración del diseño con la vanguardia se observa natural, esto es, el diseño es una disciplina abductiva y la vanguardia persigue fines prospectivos, es decir, en ambos casos se trata de objetivos de posibilidad futura. De tal suerte, este libro, emanado de una parte de las ponencias rigurosamente arbitradas del Coloquio Internacional de Diseño 2016, está dividido en tres secciones o capítulos, a saber, el capítulo uno relacionado con la teoría y metodología para proyectos de diseño de vanguardia, el segundo sobre la tecnología, la innovación y la sostenibilidad de vanguardia de dichos proyectos, y finalmente el último capítulo, vinculado con la gestión estratégica de proyectos de vanguardia.La historia se forja de hechos e interpretaciones, de pasados construidos y de presentes en procesos constantes, estudiados en forma estricta por las ciencias. Por su parte, el futuro ostenta la posibilidad de ser indefinidamente planeado con base en las variopintas aproximaciones teóricas y empíricas que dan fundamento a este tipo de ciencia; éstas son denominadas prospectivas y sus bases vanguardias. Resulta importante señalar, que estas posibilidades sólo permiten tener una idea hipotética de lo que será la realidad y el mundo de vida de los seres vivos y su contexto, no obstante, se trata de la única manera racional que tiene el ser humano de prever ese futuro posible. Las distintas ciencias y disciplinas nos permiten construir históricamente estas posibilidades partiendo de datos, hechos, significados y un sinfín de informaciones que le dan cuerpo y sentido a tales posibilidades. En este sentido, la vanguardia, como base del conocimiento prospectivo, observa la necesidad de ser escrita, leída y discutida en los términos más estrictos con el fin de volver las predicciones más precisas. El diseño por su parte, es definido de manera sucinta como la disciplina proyectual estratégica y sistémica de la posibilidad, dirigida a procesos de significación utilitaria y simbólica para la comprensión –o interpretación– y modificación –o proyectación– de niveles de realidad (referentes y sujetos) desde diversos aparatos teóricos y empíricos –perspectivas disciplinarias–
Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level
