The Pico de Navas slump (Burgos, Spain): a large rocky landslide caused by underlying clayey sand fluidification

The Pico de Navas landslide was a large-magnitude rotational movement, affecting 50x106m3 of hard to soft rocks. The objectives of this study were: (1) to characterize the landslide in terms of geology, geomorphological features and geotechnical parameters; and (2) to obtain an adequate geomechanical model to comprehensively explain its rupture, considering topographic, hydro-geological and geomechanical conditions. The rupture surface crossed, from top to bottom: (a) more than 200 m of limestone and clay units of the Upper Cretaceous, affected by faults; and (b) the Albian unit of Utrillas facies composed of silty sand with clay (Kaolinite) of the Lower Cretaceous. This sand played an important role in the basal failure of the slide due to the influence of fine particles (silt and clay), which comprised on average more than 70% of the sand, and the high content presence of kaolinite (>40%) in some beds. Its geotechnical parameters are: unit weight (δ) = 19-23 KN/m3; friction angle (φ) = 13º-38º and cohesion (c) = 10-48 KN/m2. Its microstructure consists of accumulations of kaolinite crystals stuck to terrigenous grains, making clayey peds. We hypothesize that the presence of these aggregates was the internal cause of fluidification of this layer once wet. Besides the faulted structure of the massif, other conditioning factors of the movement were: the large load of the upper limestone layers; high water table levels; high water pore pressure; and the loss of strength due to wet conditions. The 3D simulation of the stability conditions concurs with our hypothesis. The landslide occurred in the Recent or Middle Holocene, certainly before at least 500 BC and possibly during a wet climate period. Today, it appears to be inactive. This study helps to understand the frequent slope instabilities all along the Iberian Range when facies Utrillas is present.

Usos mediáticos del carisma de Dolores Ibárruri en los inicios de la Transición

El artículo ofrece un análisis de la función cumplida por Dolores Ibárruri, Pasionaria, durante la Transición a la democracia en España. Se centra en dos acontecimientos en los que la líder comunista tuvo un papel relevante: su retorno del exilio el 13 de mayo de 1977 y su presencia en la sesión inaugural de las primeras Cortes democráticas el 13 de julio de ese mismo año. A través del análisis del tratamiento de los medios de estos actos, se defenderá la idea del reciclaje del carisma, observando cómo un liderazgo carismático construido en un periodo histórico (la Guerra Civil) fue reutilizado en otro: la transición a la democracia. En este caso, con el fin de legitimar el proceso e instalar la idea de reconciliación en el relato de la Transición.

Cooperative or collaborative learning: Is there a difference in university students’ perceptions?

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

Effectiveness and cost-effectiveness of a physical activity loyalty scheme for behaviour change maintenance: a cluster randomised controlled trial

Background
Increasing physical activity in the workplace can provide employee physical and mental health benefits, and employer economic benefits through reduced absenteeism and increased productivity. The workplace is an opportune setting to encourage habitual activity. However, there is limited evidence on effective behaviour change interventions that lead to maintained physical activity. This study aims to address this gap and help build the necessary evidence base for effective, and cost-effective, workplace interventions

Methods/design
This cluster randomised control trial will recruit 776 office-based employees from public sector organisations in Belfast and Lisburn city centres, Northern Ireland. Participants will be randomly allocated by cluster to either the Intervention Group or Control Group (waiting list control). The 6-month intervention consists of rewards (retail vouchers, based on similar principles to high street loyalty cards), feedback and other evidence-based behaviour change techniques. Sensors situated in the vicinity of participating workplaces will promote and monitor minutes of physical activity undertaken by participants. Both groups will complete all outcome measures. The primary outcome is steps per day recorded using a pedometer (Yamax Digiwalker CW-701) for 7 consecutive days at baseline, 6, 12 and 18 months. Secondary outcomes include health, mental wellbeing, quality of life, work absenteeism and presenteeism, and use of healthcare resources. Process measures will assess intervention “dose”, website usage, and intervention fidelity. An economic evaluation will be conducted from the National Health Service, employer and retailer perspective using both a cost-utility and cost-effectiveness framework. The inclusion of a discrete choice experiment will further generate values for a cost-benefit analysis. Participant focus groups will explore who the intervention worked for and why, and interviews with retailers will elucidate their views on the sustainability of a public health focused loyalty card scheme.

Discussion
The study is designed to maximise the potential for roll-out in similar settings, by engaging the public sector and business community in designing and delivering the intervention. We have developed a sustainable business model using a ‘points’ based loyalty platform, whereby local businesses ‘sponsor’ the incentive (retail vouchers) in return for increased footfall to their business.

Primary Health Care Providers' Perspectives: Facilitating Older Patients' Access to Community Support Services

The purpose of the study examined in this article was to understand how non-physician health care professionals working in Canadian primary health care settings facilitate older persons’ access to community support services (CSSs). The use of CSSs has positive impacts for clients, yet they are underused from lack of awareness. Using a qualitative description approach, we interviewed 20 health care professionals from various disciplines and primary health care models about the processes they use to link older patients to CSSs. Participants collaborated extensively with interprofessional colleagues within and outside their organizations to fi nd relevant CSSs. They actively engaged patients and families in making these linkages and ensured follow-up. It was troubling to fi nd that they relied on out-of-date resources and ineffi cient search strategies to fi nd CSSs. Our fi ndings can be used to develop resources and approaches to better support primary health care providers in linking older adults to relevant CSSs. 

Étude exploratoire auprès de médecins des effets perçus d’une formation corps / esprit fondée sur les pratiques du Sensible

Résumé: Les pratiques du Sensible sont des pratiques d’accompagnement formatives et soignantes. Elles permettent d’apprendre comment l’expérience du corps et de son mouvement interne conduit au développement de la conscience et de la présence à soi ainsi qu’à l’autre, des qualités enviables pour des professionnelles et professionnels de la relation d’aide du secteur de la santé. Dans ces pratiques, le corps joue un rôle central à travers quatre types d’intervention : la thérapie manuelle, la gymnastique sensorielle, l’introspection sensorielle et l’entretien verbal à propos de l’expérience corporelle. Selon Large (2009), une qualité de présence particulière se construit chez les participantes et le participant aux pratiques du Sensible. Selon lui, ceux-ci se rapprochent de leur intériorité, parviennent à verbaliser à autrui ce qu’ils ressentent et en arrivent à poser des actions qui expriment ce qu’ils deviennent. Large (2009) constate qu’ils acquièrent de la stabilité, de l’adaptabilité et de l’autonomie. À la fois plus affirmatifs, ils gagnent aussi en proximité à l’autre. Bois (2007) note un changement de représentation lié aux idées, aux valeurs, à l’image de soi et au rapport perceptif à soi. Une chercheure et des chercheurs constatent un changement de conception de la santé (Duval, 2010; Laemmlin-Cencig et Humpich, 2009). À notre connaissance, il n’y a pas eu d’étude antérieure concernant l’influence des pratiques du Sensible auprès de médecins. Nous avons exploré, le cas échéant, comment une formation aux pratiques du Sensible, suivie par des médecins, a modifié leur rapport à leur corps, à leur propre santé, à leur conception de la santé, à la qualité de leur présence à eux-mêmes, aux autres professionnelles et professionnels et aux patientes et patients. Des entretiens semi-structurés d’une durée de 90 à 105 minutes ont été effectués auprès de six médecins français (cinq femmes et un homme) ayant été formés aux pratiques du Sensible entre 2005 et 2012. Deux types d’entretiens à visée compréhensive (Kaufmann, 2011) et d’explicitation (Vermersch, 2010; 2012) ont été réalisés. Des informations ont aussi été recueillies sur la formation et les activités professionnelles des participantes et du participant. Deux démarches d’analyse ont été utilisées, entre autres pour vérifier la cohérence des résultats et augmenter la rigueur de notre projet. Notre première démarche d’analyse a été conçue à partir de deux méthodes : au départ avec l’analyse thématique et par la suite une analyse avec les catégories conceptualisantes afin de déboucher sur une théorisation ancrée. La deuxième démarche d’analyse a consisté à créer une liste de vingt-six phénomènes présents pour la majorité des entretiens suite à des discussions tenues avec notre équipe de direction. Selon nos résultats, suite à la formation aux pratiques du Sensible, les cinq participantes témoignent d’une plus grande proximité et attention à leur corps et d’une meilleure écoute de celui-ci. Cet ancrage corporel de leur présence les informe davantage sur leur mode de vie et d’existence. Il en ressort ainsi des prises de conscience importantes grâce auxquelles les participantes font des choix nouveaux pour une vie plus cohérente et recentrée sur leur intériorité. Par le fait même, elles récupèrent leur pouvoir sur leur vie comme sur leur santé. En outre, parmi les six médecins, quatre ont modifié leur conception de la santé. Celle-ci s’est en effet élargie pour inclure de nouveaux éléments, dont la qualité du rapport à soi et l’accordage entre le corps et la pensée. Le corps semble être une voie souterraine à partir de laquelle se sont réalisées des transformations dans la personne, comme si le corps devenait une interface ayant des effets sur plusieurs facettes de la personne. Ces transformations semblent avoir une influence sur la manière dont celle-ci exerce sa profession, comme si un savoir-être renouvelé de la personne transformait son savoir-faire au sein de sa pratique. Au plan de la qualité de la présence aux autres, il est rapporté que les relations professionnelles se sont améliorées pour la majorité des participantes. Des transformations personnelles semblent avoir eu des effets sur leurs relations professionnelles. Par exemple, tous témoignent d’une meilleure qualité de présence et de disponibilité aux patientes et patients. La plupart signalent l’apprentissage d’une juste distance thérapeutique et, en même temps, d’une relation plus singulière avec chaque patiente et patient. Nous constatons par notre analyse que la relation aux patientes et patients est modifiée aux plans de la communication, du toucher et de l’écoute. Le parcours de formation des étudiantes et étudiants en médecine semble créer des conditions favorisant l’épuisement (Brazeau, Schroeder, Rovi et Boyd, 2010; Colombat, Altmeyer, Barruel, Bauchetet, Blanchard, Colombat et al., 2011; Ishak, Nikravesh, Lederer, Perry, Ogunyemi et Bernstein, 2013; Llera et Durante, 2014; Rodrigues, Albiges et Blanchard, 2012). Certaines interventions de type corps / esprit semblent pouvoir minimiser cet impact (Elder, Rakel, Heitkemper, Hustedde, Harazduk, Gerik et al., 2007; Hewson, Copeland, Mascha, Arrigain, Topol et Fox, 2006; Irving, Park-Saltzman, Fitzpatrick, Dobkin, Chen et Hutchinson, 2014; Maclaughlin, Wang, Noone, Liu, Harazduk, Lumpkin et al., 2011; Motz, Graves, Gross, Saunders, Amri, Harazduk et al., 2012; Rosenzweig, Reibel, Greeson, Brainard et Hojat, 2003; Saunders, Tractenberg, Chaterji, Amri, Harazduk, Gordon et al., 2007). Notre recherche démontre chez nos participantes et notre participant que la formation aux pratiques du Sensible leur a permis de faire plusieurs gains pour leur propre santé. Il semble qu’en amont des apprentissages liés à la profession médicale, une qualité de savoir-être puisse solidifier la personne, ses apprentissages et sa future pratique médicale. Les étudiantes et étudiants en médecine seraient ainsi mieux outillés pour traverser ce cursus de formation exigent et épuisant. Il serait intéressant de reprendre la recherche auprès d’un plus grand nombre de médecins ou d’étudiantes et étudiants en médecine afin d’y observer les éléments de théorisation répétitifs inclus dans la théorisation ancrée de notre étude exploratoire. Ainsi, selon les résultats, il serait alors plus aisé de promouvoir l’apprentissage expérientiel d’approches de type corps / esprit (dont les PS) dans les cursus universitaires en médecine.

Gait Regulation for Bipedal Locomotion

This work explores regulation of forward speed, step length, and slope walking for the passive-dynamic class of bipedal robots. Previously, an energy-shaping control for regulating forward speed has appeared in the literature; here we show that control to be a special case of a more general time-scaling control that allows for speed transitions in arbitrary time. As prior work has focused on potential energy shaping for fully actuated bipeds, we study in detail the shaping of kinetic energy for bipedal robots, giving special treatment to issues of underactuation. Drawing inspiration from features of human walking, an underactuated kinetic-shaping control is presented that provides efficient regulation of walking speed while adjusting step length. Previous results on energetic symmetries of bipedal walking are also extended, resulting in a control that allows regulation of speed and step length while walking on any slope. Finally we formalize the optimal gait regulation problem and propose a dynamic programming solution seeded with passive-dynamic limit cycles. Observations of the optimal solutions generated by this method reveal further similarities between passive dynamic walking and human locomotion and give insight into the structure of minimum-effort controls for walking.

Educación ambiental en la gestión ambiental pública de Nicaragua: análisis a partir de inspectores y educadores ambientales

La presente investigación es resultado del trabajo final de la maestría, cursada en el Programa de Pós-graduación en Educación Ambiental de la Universidad Federal de Rio Grande (FURG), en la línea de Educación Ambiental no formal. La investigación tuvo como objetivo analizar la educación ambiental en la gestión ambiental pública, a partir de la práctica de inspectores y educadores ambientales de Nicaragua, a la luz de los presupuestos y aportes de la Educación Ambiental (E.A) en los procesos de Gestión Ambiental (G.A). Los procedimientos metodológicos se desarrollaron bajo un abordaje cualitativo. Para la colecta de datos se hizo uso de la investigación bibliográfica y del método de encuesta. La metodología de análisis de datos siguió los presupuestos teóricos del Análisis Textual Discursivo (ATD). Con el análisis se evidenció que la práctica educativa es predominantemente conservacionista y pragmática. Se identificaron elementos favorables, dentro de la política educativa, para fomentar procesos dentro de una perspectiva crítica, sin embargo son poco retomadas y evidentes dentro de los planes que guían las acciones de Educación Ambiental. La E.A. no es vista como área complementar de la G.A, pero sí como un instrumento, que se integra y aplica a los procesos de formación dentro de sus áreas de acción.

Educação ambiental no contexto da extensão rural pública: a execução do programa de assessoria técnica, social e ambiental no núcleo operacional São Gabriel (RS)

O histórico de desigualdade no uso e posse das terras agricultáveis impulsionou o surgimento de políticas públicas de reforma agrária no Brasil. A principal dessas políticas, é a criação de assentamentos de reforma agrária, nos quais os assentados, além de receber um lote de terra para seu uso, são beneficiários de outras políticas públicas, entre estas, uma específica de Extensão Rural, o Programa de Assessoria Técnica, Social e Ambiental (ATES). Este programa traz em sua definição a incorporação do campo social da Educação Ambiental, colocando esta como uma atribuição dos técnicos contratados. No presente estudo, buscou-se esclarecer qual a forma que a Educação Ambiental vem sendo trabalhada no âmbito do programa de ATES, utilizando como referência as classificações descritas por Sauvé (2005) e Layrargues (2012), correntes e macrotendências, respectivamente. Para responder a essa questão, foram entrevistados membros da equipe técnica de ATES do Núcleo Operacional (NO) São Gabriel. As entrevistas foram analisadas através da metodologia intitulada Análise Textual Discursiva (ATD). As principais temáticas trabalhadas nesse sentido são o lixo doméstico, o lixo agrícola, a produção sustentável e outros assuntos que, de uma forma ou outra, estão relacionados à constituição de um ambiente. Observouse que as ações desenvolvidas pelos técnicos de ATES enquadram-se nas correntes conservacionista/recursista, biorregionalista, naturalista/recursista e naturalista, bem como apresentam aproximações, por razões diversas, com as três macrotendências existentes segundo Layrargues (2012). Também foi constatada a insatisfação dos técnicos com a forma insuficiente que a Educação Ambiental está colocada no Programa de ATES. Constatou-se também a existência de diferentes concepções sobre a categoria ambiente, as quais estão relacionadas com os fatores “histórico de vida” e “função desempenhada no âmbito do Programa”.

El derecho público en Iberoamérica. Libro homenaje al profesor Jaime Vidal Perdomo. Tomos I y II

La obra que se entrega hoy es un gran ejemplo de la riqueza académica con la que todos cuentan en Iberoamérica, motor de una nueva integración, que mueve y motiva por encima de intereses políticos y partidarios. Para una mejor lectura de las evoluciones y las expectativas en derecho público en Iberoamérica, así como del balance del derecho administrativo colombiano, en sus primeros cien años de justicia contencioso-administrativa, en este orden de ideas se ha dividido la publicación en dos tomos. El primero de ellos se divide en tres partes: derecho constitucional, teoría general del derecho administrativo, y acto y procedimiento administrativo. El segundo tomo viene distribuido en cinco partes: la primera parte se ha denominado contratos administrativos, la segunda parte régimen local, la tercera parte, denominada bienes del Estado, la cuarta parte, contencioso-administrativo y la última parte, se ha descrito como temas varios. En ella se encuentran reflexiones sobre la evolución de la teoría del daño especial en Colombia. Con lo anterior, se espera haber cumplido con un buen balance bicentenario del derecho público en Iberoamérica y del derecho administrativo colombiano en estos cien primeros años de justicia contencioso-administrativa, en homenaje al maestro Jaime Vidal Perdomo, eximio jurista colombiano consagrado al estudio y análisis del derecho público y exponente calificado y reconocido de la academia en Colombia y en los países iberoamericanos.

KNOWING THE ENEMY: NAZI FOREIGN INTELLIGENCE IN WAR, HOLOCAUST, AND POSTWAR

“Knowing the Enemy: Nazi Foreign Intelligence in War, Holocaust and Postwar,” reveals the importance of ideologically-driven foreign intelligence reporting in the wartime radicalization of the Nazi dictatorship, and the continued prominence of Nazi discourses in postwar reports from German intelligence officers working with the U.S. Army and West German Federal Intelligence Service after 1945. For this project, I conducted extensive archival research in Germany and the United States, particularly in overlooked and files pertaining to the wartime activities of the Reichssicherheitshauptamt, Abwehr, Fremde Heere Ost, Auswärtiges Amt, and German General Staff, and the recently declassified intelligence files pertaining to the postwar activities of the Gehlen Organization, Bundesnachrichtendienst, and Foreign Military Studies Program. Applying the technique of close textual analysis to the underutilized intelligence reports themselves, I discovered that wartime German intelligence officials in military, civil service, and Party institutions all lent the appearance of professional objectivity to the racist and conspiratorial foreign policy beliefs held in the highest echelons of the Nazi dictatorship. The German foreign intelligence services’ often erroneous reporting on Great Britain, the Soviet Union, the United States, and international Jewry simultaneously figured in the radicalization of the regime’s military and anti-Jewish policies and served to confirm the ideological preconceptions of Hitler and his most loyal followers. After 1945, many of these same figures found employment with the Cold War West, using their “expertise” in Soviet affairs to advise the West German Government, U.S. Military, and CIA on Russian military and political matters. I chart considerable continuities in personnel and ideas from the wartime intelligence organizations into postwar West German and American intelligence institutions, as later reporting on the Soviet Union continued to reproduce the flawed wartime tropes of innate Russian military and racial inferiority.
