Introducción: La homofobia es un importante problema social, en particular para los adolescentes. La discriminación y el desprecio a que son sometidos aquellos adolescentes homosexuales o los que tienen dudas en torno a su identidad sexual, tiene consecuencias adversas en todo su desarrollo ulterior. Detectar y enfrentar conductas homofóbicas en los colegios, resulta clave si pretendemos una sociedad justa y sana, donde la convivencia con la diversidad se respete. La UNESCO invita a todas las sociedades a enfrentar estas conductas desde la ética individual y las políticas públicas en ambientes escolares. Objetivos: Conocer la prevalencia de homofobia en los adolescentes escolarizados de un colegio de la localidad de suba en la ciudad de Bogotá e identificar los métodos preventivos. Metodología: Se aplicó una encuesta presencial auto diligenciada y dicotómica a estudiantes de sexto a once grados, indagando por variables sociodemográficas y utilizando un test cuantitativo, en donde el total de su sumatoria indica si es o no homofóbico. Resultados: Se encuestaron 843 estudiantes. El 24,9% de la población encuestada no son homofóbicos, el 49,1% aún tienen algunos prejuicios y el 26% son homofóbicos. Se compararon los homofóbicos versus los no homofóbicos entre sexo femenino y masculino obteniendo como relaciones significativas un OR de 0.25, IC 95% Li 0.16 y Ls 0.37, también se comparó la homofobia versus la no homofobia entre edades de 13-15 años con 10-12 años obteniendo OR de 0.43, Li 0,27 y Ls 0,70, entre edades de 16-19 años con 10-12 años obteniendo OR de 0.3, Li 0.17 y Ls 0.51 y finalmente entre edades de 16-19 años con 13-15 años obteniendo OR 0.68, Li 0.42 y Ls 1.09. Conclusión: La homofobia es un rechazo que se puede generar de manera involuntaria a través del desprecio y la discriminación, ya que no se tiene en común la misma orientación social, pensamientos o ideologías. Se encontró que el 26% de los adolescentes escolarizados son homofóbicos. Se evidenció mayores actitudes homofóbicas en el sexo masculino que el femenino y se observó que entre menos edad entre los adolescentes, hay más actitudes homofóbicas.

Background: Every year over 200,000 motorcyclists are killed globally. One poorly understood risk factor for motorcycle crashes is the role of motorcyclists' ability to hear traffic and other sounds around them in all directions. Most motorcycle helmets protect the head and permit vision in the forward direction, but they impair the wearer's ability to hear. This study evaluated user perceptions of Protective Helmet with Earpieces Equipped, a novel system that affixes technology onto existing motorcycle helmets to allow motorcyclists to better hear the surrounding environment in all directions. Methods: 59 Colombian traffic police agents who rode motorcycles daily completed self-report surveys about their traditional motorcycle helmet, used a Protective Helmet with Earpieces Equipped helmet for two months, and then completed a follow-up survey. We tested two hypotheses: (a) at follow-up compared to baseline, motorcyclists would report decreases in perceived safety, comfort, and ability to detect sounds with their traditional helmet, as well as increased fatigue and stress from motorcycling with their traditional helmet, and (b) at follow-up, motorcyclists would report high perceived safety and perceived importance of hearing traffic sounds in all directions while motorcycling. Wilcoxon signed-rank test evaluated hypotheses. Results: Participants rated perceived safety while using their traditional helmet to be significantly lower after using the Protective Helmet with Earpieces Equipped compared to before using it (Z=- 3.5, p less than .001). There were no changes in other variables assessed. Following use of the new helmet, participants reported greatly improved safety (M=4.56, SD=0.54, where 4=safer and 5=substantially safer) and perceived the importance of hearing traffic sounds in all directions as high. Conclusions: Improved auditory perception could increase motorcyclist safety. Participating traffic agents felt the Protective Helmet with the Earpieces Equipped greatly improved their ability to hear and improved their motorcycling safety. Perceived safety while using their traditional helmet decreased following use of the alternative. [ABSTRACT FROM AUTHOR]

This study examines the relationship between the introduction of a four-course writing-intensive capstone series and improvement in inquiry and analysis skills of biology senior undergraduates. To measure the impact of the multicourse write-to-learn and peer-review pedagogy on student performance, we used a modified Valid Assessment of Learning in Undergraduate Education rubric for Inquiry and Analysis and Written Communication to score senior research theses from 2006 to 2008 (pretreatment) and 2009 to 2013 (intervention). A Fisher-Freeman-Halton test and a two-sample Student's t test were used to evaluate individual rubric dimensions and composite rubric scores, respectively, and a randomized complete block design analysis of variance was carried out on composite scores to examine the impact of the intervention across ethnicity, legacy (e.g., first-generation status), and research laboratory. The results show an increase in student performance in rubric scoring categories most closely associated with science literacy and critical-thinking skills, in addition to gains in students' writing abilities.
