El uso del lenguaje algebraico en alumnos de bachillerato

En un intento de profundizar en la problemática de los procesos de la enseñanza, sobre todo del aprendizaje de las matemáticas, y en especial del álgebra, el Programa Nacional de Formación y Actualización de Profesores de Matemáticas (PNFAPM), del Cinvestav, inició un proyecto de investigación en el que participaron un grupo de estudiantes de la maestría en Educación Matemática y Computación Educativa de la UAEM. Este trabajo es una aportación a una de las primeras etapas de ese proyecto, llevado a cabo en la Escuela Preparatoria Diurna Uno de esa institución

Latino College Student Athletes As Nepantleras: Fostering Academic Success And Athletic Identity At Two Ncaa Division Ii Institutions

Collegiate athletic programs at National Collegiate Athletic Association (NCAA) Division II institutions in the United States serve a two-fold purpose. They offer aspiring student athletes access to college and opportunities to play competitive college sports. Consequently, student athletes at Division II institutions experience personal and institutional pressures to compete for championships while achieving academic success. Increasing demands on today’s college student athletes’ athletic participation and performance has a multitude of consequences that could influence their academic performance and success in college. Simultaneously, these institutions and athletic programs are also witnessing another phenomenon – a transformation in their student population. Latino college student athlete matriculation continues to increase every year, mirroring their non-student athlete counterparts in higher education. Their increased enrollment on these college campuses necessitates higher education researchers to better understand this understudied population. In furthering that endeavor, this inquiry sought to illuminate an overarching research question: how does a Latino college athlete’s racial identity influence their academic success and athletic performance? Guided by Gloria Anzaldúa’s Theory of Borderlands (Borderlands/La Frontera: The New Mestiza, 2012), this two-part qualitative study invited seven Latino college student athletes’ to examine their racial-ethnic identity, their academic success, and their athletic participation in Division II competitive sports. Through 12 semi-structured open-ended interviews, the researcher examined the intersections between Latino student athletes’ motivation to do well in their respective sport and their motivation to perform well academically. Among the major findings of this study, participants strongly identified themselves as Nepantleras – border crossers who possessed an intrinsic ability to seamlessly cross the world of academics and the world of athletics. Their movement across these dual world realities, in addition to balancing the expectations of their Latino familias y culturas, resulted in the participants rejecting the idea of one or the other (student or athlete) and claiming a singular identity: Soy Estudiante Deportista. Understanding and engaging with Latino college student athletes’ academic and athletic experiences at Division II institutions is vital for college faculty, athletic directors, coaches, student affairs professionals, and institutional administrators invested in their success. This study offers these institutional agents recommendations to best support their student athletes

Neuropharmacology of Vestibular System Disorders

This work reviews the neuropharmacology of the vestibular system, with an emphasis on the mechanism of action of drugs used in the treatment of vestibular disorders. Otolaryngologists are confronted with a rapidly changing field in which advances in the knowledge of ionic channel function and synaptic transmission mechanisms have led to the development of new scientific models for the understanding of vestibular dysfunction and its management. In particular, there have been recent advances in our knowledge of the fundamental mechanisms of vestibular system function and drug mechanisms of action. In this work, drugs acting on vestibular system have been grouped into two main categories according to their primary mechanisms of action: those with effects on neurotransmitters and neuromodulator receptors and those that act on voltage-gated ion channels. Particular attention is given in this review to drugs that may provide additional insight into the pathophysiology of vestibular diseases. A critical review of the pharmacology and highlights of the major advances are discussed in each case

Pressure measurements on real high-speed trains travelling through tunnels

From November, 2006 to March, 2008 a series of tests were performed onboard a wide variety of trains in order to check their response to pressure waves generated while passing through tunnels. In this communication part of the experimental results are presented, showing the pressure waves generated and focusing on the differences caused by some parameters involved such as train length and shape or tunnel lengths. The results are in accordance with the train wave signature method and the one-dimensional pressure wave theory
