Mental perceptions of urban space: using underground maps as utopian cartographies for the city of Green Bay (WI, USA)

Underground maps have become an iconic image that has transcended the function for which they were created. Their multiple visual and spatial possibilities include functioning as a cartography that simplifies and organises the perception we have of a territory. A study of the geography of perception is presented based on underground plans of the city of Green Bay prepared for the analysis (WI, USA). The methodological and educational possibilities of this utopian cartography are explored for its use as a mental map. A group of citizens’ knowledge and perception of the city they reside in is analysed through a synthetic cartography

Didactic strategies for comprehension and learning of structural concepts

p. 926-937In previous papers we have established the convenience of formulating educational strategies at the university level for both disciplines: Civil Engineering and Architecture, which involves academic topics of mutual interest by means of shared practices. As a particular matter of this approach, the application of physical experimental models is considered of special usefulness, in order to understand in better ways the performance of materials and structural systems. Several strategies of selection and development of such physical models will be discussed in this work, considering as a first step, the establishment of its correspondence with the different levels of structural complexity studied in curriculum plan: statics, strength of materials and structural design, among others. This task constitutes a part of the work program of the Laboratory of Structural Models, which is an academic project that develops and applies different didactic prototypes to structure courses in the Universidad Autónoma Metropolitana, campus Azcapotzalco, in Mexico City, project we have already presented in recent forums. Two different modes of application are implemented in classroom sessions and in structures workshop: the devices for functional demonstration of typical cases of structural work as well as the experimentation with student's own designs of destructible models where certain typologies are tested up to its failure limit. The first one allows teachers to explain adequately the theoretical principles and formulas (that usually are expressed on the blackboard) by means of didactic models identified in accordance to specific cases of the curriculum on variable level of complexity. This kind of practice allows the students of architecture and civil engineering to realize in better ways the possibilities of use and application of the different structural typologies. Such experimental models are part of more than fifty devices of the Laboratory's catalog. In the same sense, the possibility of observation of structural work of their own architectural designs, allows future professionals to achieve a better conception of the structural solutions that affect positively their designs. Based on specific predefined guides, the students develop their own architectural-structural projects and subject them to diverse loads, observing their behavior under the influence of variable stresses leading up the experiment to its last resistance. From both experiences a significant learning is obtained for the student's formation and training, who will be capable in his future professional work to use better tools of comprehension of the structural concepts applied to architecture as well as of increasing his conscience of the benefits and convenience of multidisciplinary work.Moreno, C.; Abad, A.; Gerdingh, JG.; Garcia M., C.; Gonzalez C., O.

Representational organization of novel task sets during proactive encoding

Recent multivariate analyses of brain data have boosted our understanding of the organizational principles that shape neural coding. However, most of this progress has focused on perceptual visual regions (Connolly et al., 2012), whereas far less is known about the organization of more abstract, action-oriented representations. In this study, we focused on humans{\textquoteright} remarkable ability to turn novel instructions into actions. While previous research shows that instruction encoding is tightly linked to proactive activations in fronto-parietal brain regions, little is known about the structure that orchestrates such anticipatory representation. We collected fMRI data while participants (both males and females) followed novel complex verbal rules that varied across control-related variables (integrating within/across stimuli dimensions, response complexity, target category) and reward expectations. Using Representational Similarity Analysis (Kriegeskorte et al., 2008) we explored where in the brain these variables explained the organization of novel task encoding, and whether motivation modulated these representational spaces. Instruction representations in the lateral prefrontal cortex were structured by the three control-related variables, while intraparietal sulcus encoded response complexity and the fusiform gyrus and precuneus organized its activity according to the relevant stimulus category. Reward exerted a general effect, increasing the representational similarity among different instructions, which was robustly correlated with behavioral improvements. Overall, our results highlight the flexibility of proactive task encoding, governed by distinct representational organizations in specific brain regions. They also stress the variability of motivation-control interactions, which appear to be highly dependent on task attributes such as complexity or novelty.SIGNIFICANCE STATEMENTIn comparison with other primates, humans display a remarkable success in novel task contexts thanks to our ability to transform instructions into effective actions. This skill is associated with proactive task-set reconfigurations in fronto-parietal cortices. It remains yet unknown, however, how the brain encodes in anticipation the flexible, rich repertoire of novel tasks that we can achieve. Here we explored cognitive control and motivation-related variables that might orchestrate the representational space for novel instructions. Our results showed that different dimensions become relevant for task prospective encoding depending on the brain region, and that the lateral prefrontal cortex simultaneously organized task representations following different control-related variables. Motivation exerted a general modulation upon this process, diminishing rather than increasing distances among instruction representations

Migración de jóvenes, adolescentes y niños mexiquenses a Estados Unidos: una lectura sociodemográfica

Los flujos migratorios entre México y Estados Unidos tienen una larga tradición, no obstante, hay escasez de información respecto a la migración de los menores entre ambos países. Este trabajo hace un diagnóstico de la migración de menores, principalmente del Estado de México y trata el tema de la vulnerabilidad de los menores migrantes, que se acentúa y se recrudece por diversos elementos, como su edad y su condición migratoria. Cabe señalar que en los estudios censales publicados por el Instituto Nacional de Estadística y Geografía ( inegi ) en 2000 y 2010 es posible observar un incremento de los menores migrantes de retorno, ya que en el año 2000 la cifra fue de 73 544, mientras que para 2010 fue de 176 345. El documento finaliza con una serie de propuestas para el desarrollo de políticas por parte del Estado y señala la necesidad de apoyar la realización de proyectos de investigación sobre el tema, ya que, como se mencionó anterior - mente, la información al respecto es escasa.Los flujos migratorios entre México y Estados Unidos tienen una larga tradición, no obstante, hay escasez de información respecto a la migración de los menores entre ambos países.

Addressing Health Disparities and Cultural Competency in Reproductive Health Through Active Learning in the University of Puerto Rico, School of Medicine

Introduction: Lesbian, gay, bisexual, transgender and queer (LGBTQ) individuals face health disparities linked to societal stigma, discrimination, and denial of their civil and human rights which impact reproductive health. Previous pregnancy, induced abortion, and hormonal contraceptive use are common among women who report sex with women, regardless of self-identification as lesbian. LGBTQ have higher risk of smoking, use illicit drugs or have alcohol related problems. Methods: A faculty development training addressed methods and skills for teaching cultural competence and eliminate health disparities. Faculty facilitated a small group active learning activity, including a vignette and a reflective self-evaluation, for medical students to provide better health care services to LGBTQ women in childbearing age. A pre-test and post-test were administered. Analysis was performed using Statistix8.0. Results: A total of 115 second year medical students were included in the educational activity. Subjects included 101 students (87%) on the pretest and 104 students (90%) on the post-test. Subjects showed an overall improvement in knowledge (89% correct answers pre-test, 100% post-test, (

Primordial magnetic fields from preheating at the electroweak scale

We analyze the generation of helical magnetic fields during preheating in a model of low-scale electroweak (EW) hybrid inflation. We show how the inhomogeneities in the Higgs field, resulting from tachyonic preheating after inflation, seed the magnetic fields in a way analogous to that predicted by Vachaspati and Cornwall in the context of the EW symmetry breaking. At this stage, the helical nature of the generated magnetic fields is linked to the non-trivial winding of the Higgs-field. We analyze non-perturbatively the evolution of these helical seeds through the highly non-linear stages of symmetry breaking (SB) and beyond. Electroweak SB occurs via the nucleation and growth of Higgs bubbles which squeeze the magnetic fields into string-like structures. The W-boson charge density clusters in lumps around the magnetic strings. After symmetry breaking, a detailed analysis of the magnetic field Fourier spectrum shows two well differentiated components: a UV radiation tail at a temperature T ~ 0.23 m_higgs slowly growing with time, and an IR peak associated to the helical magnetic fields, which seems to follow inverse cascade. The system enters a regime in which we observe that both the amplitude (\rho_B/\rho_{EW} ~ 0.01) and the correlation length of the magnetic field grow linearly with time. During this stage of evolution we also observe a power-law growth in the helical susceptibility. These properties support the possibility that our scenario could provide the seeds eventually evolving into the microgauss fields observed today in galaxies and clusters of galaxies.Comment: 55 pages, late

Boardgames as learning activities in STEM degrees

A serious game (also known as applied game or educational game) is a game designed not only for entertainment, but also for educational purposes. The term “Serious Game” has been normally used for video games, but it can also be applied to toys and boardgames. This paper addresses the use of serious boardgames as learning activities in STEM university degrees. All boardgames are somehow educational for the age and level they are designed, as they stimulate, among other things, reading comprehensions, writing, mental arithmetic, strategy or creativity. Educational serious boardgame are those designed with enough exactness on a specific topic that favor learning about that topic while playing. This is the principle of learning-by-playing or gamification, and it has shown advantages at engaging students. It should be noted that an educational game is not necessarily a game based on how much someone knows about something, like the famous trivial pursuit, but a game that allows you learning (almost unconsciously) while you play. Despite there are many games designed for adults, in particular for students in a university level in a STEM degree, the use of boardgames as learning activities is not a typical practice yet. It is normally unfeasible to “play the games” during the classes. But boardgames can be incorporated as learning activities in different ways. Herein, the following strategies will be discussed: (1) Including selected boardgames in the recommended bibliography, (2) encouraging the debate about the validity and exactness of the experimented games, and (3) designing boardgames based on the content of the course.Universidad de Málaga.

Estudio comparativo de equipos fijos de pedestal y su aplicación en la detección del tráfico incontrolado de material radiactivo en aeropuertos

En este trabajo se analiza la respuesta de tres equipos comerciales, diseñados para detectar el tráfico ilícito o el desplazamiento involuntario de material radiactivo en aeropuertos cuando es transportado por los pasajeros. Se han comparado tres instrumentos fijos de pedestal: el equipo APM de Bicron, el equipo GR-606 de Exploranium y el equipo FHT-1372 de Thermo Eberline. En esta evaluación inicial, realizada en el Laboratorio de Ingeniería Nuclear de la Escuela de Caminos, Canales y Puertos, se observó que el equipo FHT-1372 presentó una respuesta de detección más rápida, sensible y permitió la medida de tasa de dosis total y tasa de dosis artificial. Este equipo fue instalado en la salida de la aduana de pasajeros del aeropuerto internacional de Barajas durante un periodo operativo de 108 días en el año 2002 y pasaron un total de 1.339.931 personas. Este periodo se dividió en 5 sesiones para poder establecer los niveles de investigación adecuados para detectar una posible incidencia de material radiactivo, que finalmente se fijaron en 110 nSv/h para la tasa de dosis total y 25 nSv/h para la tasa de dosis artificial. Durante dicho periodo se detectaron 39 posibles incidencias por encima del límite de investigación establecido para las diferentes sesiones, 5 de ellas con un valor 10 veces superior al fondo ambiental de la sala donde se instaló el equipo (alrededor de 90 nSv/h) y ninguna superó el nivel de 100 μSv/h a 1 m de distancia que la Organización Internacional de la Energía Atómica (OIEA) establece como límite para el transporte lícito de material radiactivo
