Using visual art and collaborative reflection to explore medical attitudes toward vulnerable persons

Background: Vulnerable persons often face stigma-related barriers while seeking health care. Innovative education and professional development methods are needed to help change this.Method: We describe an interdisciplinary group workshop designed around a discomfiting oil portrait, intended to trigger provocative conversations among health care students and practitioners, and we present our mixed methods analysis of participant reflections.Results: After the workshop, participants were significantly more likely to endorse the statements that the observation and interpretive skills involved in viewing visual art are relevant to patient care and that visual art should be used in medical education to improve students’ observational skills, narrative skills, and empathy with their patients.  Subsequent to the workshop, significantly more participants agreed that art interpretation should be required curriculum for health care students. Qualitative comments from two groups from two different education and professional contexts were examined for themes; conversations focused on issues of power, body image/self-esteem, and lessons for clinical practice.   Conclusions: We argue that difficult conversations about affective responses to vulnerable persons are possible in a collaborative context using well-chosen works of visual art that can stand in for a patient

Upper limits for undetected trace species in the stratosphere of Titan

In this paper we describe a first quantitative search for several molecules in Titan's stratosphere in Cassini CIRS infrared spectra. These are: ammonia (NH3), methanol (CH3OH), formaldehyde (H2CO), and acetonitrile (CH3CN), all of which are predicted by photochemical models but only the last of which observed, and not in the infrared. We find non-detections in all cases, but derive upper limits on the abundances from low-noise observations at 25{\deg}S and 75{\deg}N. Comparing these constraints to model predictions, we conclude that CIRS is highly unlikely to see NH3 or CH3OH emissions. However, CH3CN and H2CO are closer to CIRS detectability, and we suggest ways in which the sensitivity threshold may be lowered towards this goal.Comment: 11 pages plus 6 figure file

Witness: The Modern Writer as Witness

Editor\u27s Note [Excerpt] Magic can mean many different things, especially for writers. Magic can be an illusion, a sleight of hand designed to trick onlookers into believing the impossible. Or magic can be a supernatural force in a world of harsh reality, a set of beliefs that sits just outside the realms of organized religion and advanced technology. Wizards and demons, Las Vegas entertainers and houngans --they all practice a kind of sorcery. For poets and prose writers, though, magic affords an opportunity for us to stretch the limitations of the physical world in search of new themes, settings, and characters. Magic is a door we eagerly walk through to reach new lands. We at Witness have thoroughly enjoyed the process of selecting the themed works we have collected here, mainly because the idea of enchantment is inspiring. There is the possibility of positive charms; there is a chance for dark witchery. And sometimes the spell cast by a character is nebulous, difficult to categorize. It’s arguable that we cherish these incantations the most, since they leave us in a state of wonderment bordering on disorientation. Yes, magic can also leave us bewildered and thankful for the bewilderment.https://digitalscholarship.unlv.edu/witness/1001/thumbnail.jp

Aging in the Right Place

Background: This project builds upon a pilot study that documented innovative shelter/housing solutions that have not undergone rigorous evaluation but hold the promise of supporting “aging in the right place” for older persons (50+) with experiences of homelessness (OPEH) in Montreal, Calgary, and Vancouver. “Aging in the right place” means older adults remain in their homes and communities supported by housing, health, social services responsive to their unique lifestyles and needs. While our pilot study identified innovative shelter/housing solutions that support OPEH to establish and maintain a home and work towards aging in the right place, there remains a knowledge gap regarding what works, why it works, and for whom it works. Methods/Design: Through a community-based participatory research approach, we will conduct evaluations of 11 different promising shelter/housing practices to determine the types of practices that appear most useful in supporting aging in the right place, and the groups of OPEH for whom the promising practices work based on intersections of risk (e.g., age, gender, sexual orientation, race/ethnicity, disability, Indigenous status, and immigrant status). Our overall goal is to improve the shelter/housing options to meet the unique and complex health and social needs of OPEH across Canada. Discussion: Program evaluations will offer practice-based evidence of ways in which promising practices of shelter/housing might serve as best practices for supporting OPEH to establish and maintain a home and work towards aging in the right place. Project findings will inform housing, homelessness, health, and social service providers’ design and delivery of programs for OPEH to improve the sustainability of community housing, build provider capacity, and ensure supports that promote aging in the right place are sustained

Segmentación de imágenes utilizando campos aleatorios de Markov

Segmentation is a process used in machine vision is to divide a scene into a set of regions, facilitating the task of interpretation of an image. Segmentation algorithms are  based on criteria such as homogeneity of the region and discontinuity between adjacent disjoint regions. This article describes and implements a segmentation model us-ing stochastic decision processes, which requires the support and computing time to achieve optimal cloud, but, among other advantages, it tends to be local and leads to a parallel hardware implementation naturally.la segmentación es un proceso utilizado en visión artificial que consiste en dividir una escena en un conjunto de regiones, facilitando con ello la tarea de interpretación de una imagen. Los algoritmos de segmentación se basan en criterios como homogeneidad de la región y discontinuidad entre regiones disjuntas adyacentes. El presente artículo describe e implementa un modelo de segmentación que usa procesos de decisión estocásticos, el cual requiere apoyo y tiempo de computación para conseguir etiquetas óptimas, pero, entre otras ventajas, tiende a ser local y conduce a una implementación en hardware paralelo de manera natural

On the abundance of non-cometary HCN on Jupiter

Using one-dimensional thermochemical/photochemical kinetics and transport models, we examine the chemistry of nitrogen-bearing species in the Jovian troposphere in an attempt to explain the low observational upper limit for HCN. We track the dominant mechanisms for interconversion of N2-NH3 and HCN-NH3 in the deep, hightemperature troposphere and predict the rate-limiting step for the quenching of HCN at cooler tropospheric altitudes. Consistent with other investigations that were based solely on time-scale arguments, our models suggest that transport-induced quenching of thermochemically derived HCN leads to very small predicted mole fractions of hydrogen cyanide in Jupiter's upper troposphere. By the same token, photochemical production of HCN is ineffective in Jupiter's troposphere: CH4-NH3 coupling is inhibited by the physical separation of the CH4 photolysis region in the upper stratosphere from the NH3 photolysis and condensation region in the troposphere, and C2H2-NH3 coupling is inhibited by the low tropospheric abundance of C2H2. The upper limits from infrared and submillimeter observations can be used to place constraints on the production of HCN and other species from lightning and thundershock sources.Comment: 56 pages, 0 tables, 6 figures.
