La producción de la (in)exclusión, currículo y cultura(s) en el aula de matemáticas

El propósito de este artículo es compartir las posibilidades de reinvención de un camino de constitución de subjetividades sociales incluyentes en el aula de matemáticas, donde la exclusión del aprendizaje y la exclusión social coexisten. Lo haré desde investigaciones realizadas en aulas de matemáticas en las que la (in)exclusión en la participación de estudiantes es evidente. Desde la perspectiva sociopolítica de la educación matemática y con argumentos procedentes de la teoría crítica del currículo y de los estudios foucaultianos en educación, analizaré, primero, el relato de la inclusión de las matemáticas escolares en dos reformas curriculares de las matemáticas. Cuestiono los posibles significados de los sistemas de razón como prácticas históricas que normalizan y construyen las tesis culturales sobre la (in)exclusión. Propongo la dimensión cultural en el aula de matemáticas como una noción nodal en las prácticas de aprendizaje y enseñanza de las matemáticas para constituir subjetividades sociales incluyentes. Abordar estos problemas nos permite avanzar en comprender por qué y cómo las matemáticas escolares pueden contribuir con una sociedad más justa

BARRIERS TO GENDER-AFFIRMING CARE

The purpose of this study was to examine the experiences of transgender and nonbinary individuals who have accessed or are thinking of seeking gender-affirming medical care in a rural California county. The study adopted a post-positivist approach, and data was gathered from ten qualitative interviews with study participants. In the data analysis phase, the researcher utilized a bottoms-up approach and engaged in open, axial, and selective coding. Data analysis of qualitative interviews revealed sixteen open codes and connections between these codes. These codes were then categorized into three themes: the impact of an individual’s experience when accessing care, barriers to gender-affirming care in a rural area, and client-centered suggestions for mitigating barriers to care. After examining the data, the researcher identified the need for a culturally competent, individualized, and inclusive approach to gender-affirming a rural California county as the core concept arising from the data. This concept is explored, and transgender and nonbinary participants propose suggestions for achieving this. These suggestions include updating medical forms to be inclusive, implementing robust, culturally competent training for medical providers and their staff, and offering an individualized approach to care that meets the needs of the individual and their transition. This research contributes to both micro and macro levels of social work by highlighting the experiences and needs of transgender and nonbinary individuals in rural California. This can impact clinical practice and aid in creating and implementing inclusive provider policies

Implicit Cooperative Positioning in Vehicular Networks

Absolute positioning of vehicles is based on Global Navigation Satellite Systems (GNSS) combined with on-board sensors and high-resolution maps. In Cooperative Intelligent Transportation Systems (C-ITS), the positioning performance can be augmented by means of vehicular networks that enable vehicles to share location-related information. This paper presents an Implicit Cooperative Positioning (ICP) algorithm that exploits the Vehicle-to-Vehicle (V2V) connectivity in an innovative manner, avoiding the use of explicit V2V measurements such as ranging. In the ICP approach, vehicles jointly localize non-cooperative physical features (such as people, traffic lights or inactive cars) in the surrounding areas, and use them as common noisy reference points to refine their location estimates. Information on sensed features are fused through V2V links by a consensus procedure, nested within a message passing algorithm, to enhance the vehicle localization accuracy. As positioning does not rely on explicit ranging information between vehicles, the proposed ICP method is amenable to implementation with off-the-shelf vehicular communication hardware. The localization algorithm is validated in different traffic scenarios, including a crossroad area with heterogeneous conditions in terms of feature density and V2V connectivity, as well as a real urban area by using Simulation of Urban MObility (SUMO) for traffic data generation. Performance results show that the proposed ICP method can significantly improve the vehicle location accuracy compared to the stand-alone GNSS, especially in harsh environments, such as in urban canyons, where the GNSS signal is highly degraded or denied.Comment: 15 pages, 10 figures, in review, 201

Influence of thromboembolic events in the prognosis of COVID-19 hospitalized patients. Results from a cross sectional study

Background COVID-19 may predispose to both venous and arterial thromboembolism event (TEE). Reports on the prevalence and prognosis of thrombotic complications are still emerging. Objective To describe the rate of TEE complications and its influence in the prognosis of hospitalized patients with COVID-19 after a cross-sectional study. Methods We evaluated the prevalence of TEE and its relationship with in-hospital death among hospitalized patients with COVID-19 who were admitted between 1st March to 20th April 2020 in a multicentric network of sixteen Hospitals in Spain. TEE was defined by the occurrence of venous thromboembolism (VTE), acute ischemic stroke (AIS), systemic arterial embolism or myocardial infarction (MI). Results We studied 1737 patients with proven COVID-19 infection of whom 276 died (15.9%). TEE were presented in 64 (3.7%) patients: 49 (76.6%) patients had a VTE, 8 (12.5%) patients had MI, 6 (9.4%%) patients had AIS, and one (1.5%) patient a thrombosis of portal vein. TEE patients exhibited a diffuse profile: older, high levels of D-dimer protein and a tendency of lower levels of prothrombin. The multivariate regression models, confirmed the association between in-hospital death and age (odds ratio [OR] 1.12 [95% CI 1.10–1.14], p<0.001), diabetes (OR 1.49 [95% CI 1.04–2.13], p = 0.029), chronic obstructive pulmonary disease (OR 1.61 [95% CI 1.03–2.53], p = 0.039), ICU care (OR 9.39 [95% CI 5.69–15.51], p<0.001), and TTE (OR 2.24 [95% CI 1.17–4.29], p = 0.015). Conclusions Special attention is needed among hospitalized COVID-19 patients with TTE and other comorbidities as they have an increased risk of in-hospital death.We thank HM Hospitales for making their data publicly available as part of the COVID Data Save Lives project

Violencia de género en la familia: perspectiva jurídico penal

Se analizan desde una perspectiva garantista la Constitución Federal y los tratados internacionales que obligan al Estado a tutelar penalmente el derecho humano de la mujer a una vida libre de violencia en el hogar. Se concluye que para cumplir con este deber es ineludible la creación legislativa de tipo penal que sancione la violencia familiar asociada a la violencia de género. Esta acción legislativa sería parte de una nueva política criminológica dedicada específicamente a la prevención, sanción y erradicación de la violencia de género en el hogar

Cuidar de sí misma, un reto sin igual. El sentido otorgado por las enfermeras quirúrgicas

Objetivo: Analizar la representación social de las enfermeras del área quirúrgica respecto al cuidado de si. Método: Estudio cualitativo llevando a cabo con 32 enfermeras de 28 a 45 años de edad. se utilizó como referencia la teoría de las Representaciones Sociales. La recolección de datos fue realizada a través de la entrevista semiestructurada y se optó por el análisis de contenido que permitió la elaboración de las categorías que facilitan la comprensión de los datos. Resultados: los relatos revelan que el cuidado constituye una acción de vida, donde la enfermera transmite desde su interior un modo de relación con sus pares. Conclusión: Estos relatos muestran que la enfermera quirúrgica desarrolla un conocimiento orientado a cubrir las necesidades del otro, situación que representa una conducta derivada del valor que la persona le asigne para cuidar
