Authors: Kahika Giles , Karyeija Gerald K.
Published: July 2017

The study examined the relationship between institutional roles and the implementation of Local Economic Development (LED) in Uganda, taking Kasese District as a case study. The study objectives were to examine how technical roles, political roles, Civil Society Organisations and private sector roles affect implementation of LED implementation in Kasese District Local Government. The study was a correlational research design that adopted both quantitative and qualitative approaches. A sample of 120 respondents were observed using questionnaires and interviews. Data were analysed using Pearson correlation coefficient and regressions analysis. The study findings revealed that there is a positive significant relationship between technical roles, political roles, civil society roles and private sector roles with the implementation of LED. The study recommended among others, that local governments should be assisted to create efficacious LED institutions and create LED implementation planning frameworks involving key actors and stakeholders at locality level.
High Order Well-Balanced Weighted Compact Nonlinear Schemes for Shallow Water Equations
Authors: Gao Zhen , Hu Guanghui
Published: July 2017

In this study, a numerical framework of the high order well-balanced weighted compact nonlinear (WCN) schemes is proposed for the shallow water equations based on the work in [S. Zhang, S. Jiang, C.-W Shu, J. Comput. Phys. 227 (2008) 7294-7321]. We employ a special splitting technique for the source term proposed in [Y. Xing, C.-W Shu, J. Comput. Phys. 208 (2005) 206-227] to maintain the exact C-property, which can be proved theoretically. In the meantime, the genuine high order accuracy of the numerical scheme can be observed successfully, and small perturbation of the stationary state can be resolved and evolved well. In order to capture the strong discontinuities and large gradients, the fifth-order upwind weighted nonlinear interpolations together with the fourth/sixth order cell-centered compact scheme are used to construct different WCN schemes. In addition, the local characteristic projections are considered to further restrain the potential numerical oscillations. A variety of representative one- and two-dimensional examples are tested to demonstrate the good performance of the proposed schemes.
Electrophoresis of a Cylinder in a Cylindrical Tube
Authors: Feng Huicheng , Wong Teck Neng
Published: July 2017

Electrophoresis of a cylinder suspended in a cylindrical tube is analytically studied in the limit of thin electric double layer approximation. The electric and fluid flow fields within the annulus, and the cylinder velocities are analytically obtained in bipolar coordinates. The results are analyzed with various values of dimensionless parameters: eccentricity, cylinder-to-tube radius ratio and tube-to-cylinder zeta potential ratio (i.e., tube-to-cylinder velocity scale ratio). The analysis shows that microvortices are generated within the annulus. By changing the parameters, different flow patterns can be created, which shows potential for mixing enhancement in micro/nanofluidics. Moreover, the cylinder not only translates but also rotates when the cylinder and tube are eccentric. The cylinder rotation might be utilized as a micromotor or an electric field detector. The cylinder trajectories show that the cylinder may approach the tube wall or rest within the tube depending on the zeta potential ratio.
¿Dónde está el ‘arte’ en la investigación artística?
Authors: Vilar Gerard
Published: July 2017

En muchas ocasiones, visitando exposiciones de investigación artística, o viendo ‘exposiciones’ en el Journal of Artistic Research, uno acaba preguntándose dónde está el arte en esos proyectos, puesto que tal vez los podrían haber realizado historiadores, antropólogos o comunicólogos y haber exhibido sus resultados en un museo de historia, un museo de etnología o un centro cultural, en lugar de un centro artístico. Sin duda, normalmente son auténticas investigaciones, pero ¿dónde está el arte? Una respuesta satisfactoria al problema de dónde se encuentra el arte en la investigación artística hay que buscarla en la diferencia entre una presentación o display informativo y un auténtico dispositivo para la reflexión. Los científicos sociales producen teoría, información y conocimiento fáctico. Los artistas no producen principalmente conocimiento fáctico, sino que crean dispositivos para la generación de conocimientos. Si se borra completamente esta distinción, el riesgo es tener mala ciencia y/o mal arte, o incluso no tener ni una ni otro. Para construir una argumentación filosófica adecuada a la intuición que acabamos de formular, puede recurrirse a las tesis de Deleuze acerca de los perceptos como el tipo de ideas que los artistas crean, a diferencia de los científicos que crean funciones y de los filósofos que crean conceptos.
Ecología global, sensibilidades locales. El rol de las humanidades ambientales frente a la crisis ecosocial contemporánea
Authors: Albelda Raga José , Sgaramella Chiara
Published: July 2017

El proyecto de investigación interdisciplinar I+D+i titulado Humanidades ambientales. Estrategias para la empatía ecológica y la transición hacia sociedades sostenibles indaga el papel de la ética, de las artes visuales y de la literatura en el proceso de transformación necesario para establecer modelos culturales más eco-compatibles. En efecto, la crisis ecológica y social que vivimos plantea unos interrogantes profundos que nos obligan a repensarnos como seres humanos y como sociedad. Si bien existen significativos avances tecnocientíficos en el ámbito de la eficiencia energética o de la restauración ecosistémica, consideramos que para contrarrestar las poderosas inercias desarrollistas que caracterizan el paradigma actual es preciso potenciar un cambio de cosmovisión general de las sociedades, incluyendo su imaginario colectivo. En este sentido, las humanidades pueden cumplir un papel relevante en forjar nuevos valores e imaginar otras formas de convivencia social.

La presente comunicación recoge algunas de las propuestas presentadas en el primer seminario de investigación vinculado al ya mencionado proyecto I+D+i que tuvo lugar en la Universitat Politècnica de València en noviembre de 2016. En concreto, se exploran diferentes métodos de investigación desde las humanidades para abordar la dimensión global y local de la transición a la sostenibilidad. En primer lugar, se plantea un enfoque interdisciplinar para el estudio de fenómenos de escala planetaria, como la crisis energética y climática; junto a ello, se proponen talleres creativos vinculados a iniciativas ecológicas ciudadanas para conectar la investigación académica a los conocimientos locales. Finalmente, se evalúa la influencia y el potencial transformador de proyectos de creación artística y vinculados a una noción ampliada de site specific y a procesos de creación colaborativos en diálogo con las comunidades humanas e incluso con los elementos bióticos y abióticos del ecosistema.
Visualizando la ciudad glocal. Modelos y paradigmas de una relación creativa entre el dato y su representación en el entorno arquitectónico
Authors: Mañas Carbonell Moisés , Martínez Cuenca Raquel
Published: July 2017

Partiendo de entender la ciudad como un deseo, como intercambio, como ciudades imposibles, que apuntaba Italo Calvino en su texto Las Ciudades invisibles, y de la relación de estetización del dato en las ciudad contemporánea, a través de la mirada de Gilles Lipovetsky; este estudio pretende mostrar una reflexión sobre la relación del flujo de datos, sus representaciones estéticas y funcionales en los nuevos espacios arquitectónicos tecnificados que generan una nueva ciudad glocal mediada. Reflexionar sobre los dispositivos existentes de mediación entre la estaticidad de la arquitectura y el dinamismo del dato y como este binomio, su relación, su tecnificación a través de propuestas creativas y lúdicas puede convertirse en una nueva propuesta de recorrido urbano amplificado para el ciudadano-usuario contemporáneo.
Inframedia: barreras infraestructurales y ecologías online en la Web 2.0
Authors: Sánchez López José
Published: July 2017

Nuestra inteligencia colectiva y con ella nuestro posicionamiento “glocal” dependen estrechamente de la operación a gran escala de los media existentes en las redes (motores de búsqueda, redes sociales, Wikis etc.). El origen digital de tales medios, y su dependencia de las ciencias de la computación las hace adoptar formas distintivas en relación específica con el diseño de software. Dada esta situación, es importante señalar la condición limitada, particular a nuestro contacto fenomenológico y cognitivo con las infraestructuras de red que lo soportan.

El presente trabajo trata de resumir una investigación personal sobre la visualidad en las redes, que tiene por objetivo proveer de contexto teórico a una próxima experimentación artística en el ámbito de los nuevos medios. Ésta, órbita alrededor de una serie de cuestiones que surgen en relación con la noción de “interfaz cibernética”, entendida como la parte visible de todo un complejo infraestructural.

Se destacan cuatro principales focos de incidencia: 1. Valoración de la estructura en capas de abstracción funcional, propias de la gestión mediada: arquitectura, protocolos y algoritmos que componen la “vida” tecno-material de la red. 2. La doble acepción de “colectividad” en las redes: la generación de contenidos por parte de usuarios, y su oscilación entre lo procomún y la recolección de datos. 3. Atención al término acuñado por James Bridle: “New Aesthetics”, y la iniciativa de señalar la creciente autonomía de lo digital en su vocación de referir lo real desde sus propios términos. Circunstancia puesta en relación con las inquietudes de la sociología contemporánea por considerar la implicación de los agentes no-humanos en las dinámicas sociales propias de la ecología on-line. 4. Impacto sobre casos concretos: prácticas artísticas contemporáneas sujetas al contexto digital desde sus estrategias formales, sea en complicidad, o en actitud de resistencia en un ejercicio de contra-diseño.
Espacios de memoria virtual como laboratorios de investigación artística
Authors: Veciana Stella
Published: July 2017

Esta comunicación hace una reflexión teórica sobre metodologías artísticas en la generación de ‘espacios de memoria en línea’, la influencia de códigos y valores culturales sostenibles en estos espacios y expone dos casos particulares de archivos digitales dinámicos en el contexto de conferencias científicas para la sostenibilidad y de una biblioteca pública como ejemplos de laboratorios de investigación científico-artística de tipología a/sincrónica y de tipología virtual.

El archivo clásico analógico pasa del espacio del museo a la memoria dinámica en redes de bancos de datos hasta nuevos entornos híbridos de realidades mixtas. ¿En qué se diferencia el modelo de archivo moderno como la biblioteca presencial de los modelos de archivo de bases de datos y su conectividad por las tecnologías de Internet? ¿Cómo se caracteriza la memoria social que se sirve de sistemas de base de datos interactivas? Los ‘espacios de memoria online’ transforman el concepto de archivo, que cumplía funciones de conservación de patrimonio cultural, para convertirse asimismo en centro de producción estético-científica como en los experimentos de participación colectiva en ‘monumentos virtuales’ que activan procesos de memoria social.

Sobre la base de esta transformación histórica y enfoques metodológicos artístico-científicos interculturales, el objetivo de la comunicación será presentar el espacio de la memoria dinámica online como laboratorios futuros de investigación científico-artística.
Concomitant Hip Arthroscopy and Periacetabular Osteotomy: Is there a Difference in Perioperative Complications compared with Periacetabular Osteotomy Alone?
Authors: Olson Steven A , Neumann Julie A , Rickert Kathleen D , Lewis Brian D , Bradley Kendall E , France Monet A
Published: July 2017

Purpose

To evaluate the safety of hip arthroscopy combined with a periacetabular osteotomy (PAO) compared with PAO alone in treating concomitant intra-articular pathology in hip dysplasia.

Materials and methods

Forty-one patients (46 hips) with symptomatic hip dysplasia were retrospectively reviewed. Pre- and postoperative radiographic data and intraoperative data consisting of estimated blood loss, intraoperative and postoperative blood transfusions, operative time, and length of hospital stay were recorded. The complications occurring within the first 3 months after surgery including lateral femoral cutaneous and pudendal nerve neuropraxia, wound complications, and reoperations were recorded. Additionally, rates of deep venous thrombosis and other major adverse outcomes (myocardial infarction, pulmonary embolism, stroke, death) were examined.

Results

Twenty-one patients (24 hips) underwent PAO alone. Twenty patients (22 hips) underwent hip arthroscopy followed immediately by PAO. There were no significant differences in the 90-day complication rates between the two groups, comparing the rate of neuropraxia (p = 0.155) and wound complications (p = 0.6). Operative time for PAO alone was 179 minutes (standard deviation [SD] ± 37) compared with 251 minutes (SD ± 52) for combined hip arthroscopy and PAO (p < 0.001). No incidence of deep vein thrombosis or major adverse events was noted in either group. Preoperative lateral center edge angle (LCEA) and acetabular index (AI) were 14° and 20° respectively, in the PAO-alone group and 19° and 16° respectively, in the combined group. Postoperatively, LCEA was 29° in the PAO-alone group and 30° in the combined group. Postoperative AI was 11° in the PAO-alone group and 5° in the combined group.

Conclusion

This study demonstrates that hip arthroscopy in combination with PAO to treat intra-articular pathology shows no difference in 90-day complication rates when compared with PAO alone.

Level of evidence

Prototype
Authors: Valentine Louise
Published: July 2017

Design in the 21st century has become increasingly more embedded in a complex system of disciplines (software and digital design, graphic design, architecture, construction, medical practices, business design and management, technology, graphic design, product design, etc.) and as a result, the intricacies of designing a product have increased. How can NASA test products for alien environments on Earth? How can a designer successfully test a digital program for a space that is not tangible? It is these problems that this collection responds to, allowing the reader to understand the significance of the prototype in modern design, and how designers must use this process to predict the potential future of their product.
Prototype enables design students and professionals to explore the significance of the prototype and its influence and bearing on the future of design. As the prototype is a model of something not yet built, a kind of future in the present, its importance in the development of the finished product cannot be ignored. It allows designers to understand what needs to be changed and what needs to be manipulated in order to create a product that successfully understands and navigates all the complexities of the modern world. In this way, the book allows us to rethink the nature of the prototype for the 21st century and beyond.
Contemporary Crafts
Authors: Racz Imogen
Published: July 2017

Contemporary Crafts explores craft practices in both North America and Britain, revealing an astonishingly rich and diverse picture of artisanal work today.

The book ranges across both urban and rural crafts and analyses how the country/city dichotomy creates differing approaches, practices and objects. Analysed in the context of their environment and its localised history, crafted objects are shown to embody or critique particular urban/rural myths and traditions.

Covering both traditional and cutting-edge crafts from the small-scale domestic to large outdoor works, Contemporary Crafts demonstrates how craftspeople today are responding to the changing creative contexts of culture and history.
The Invention of Craft
Authors: Adamson Glenn
Published: July 2017

Glenn Adamson’s last book, Thinking Through Craft, offered an influential account of craft’s position within modern and contemporary art. Now, in his engaging sequel, The Invention of Craft, his theoretical discussion of skilled work is extended back in time and across numerous disciplines.

Adamson searches out the origins of modern craft, locating its emergence in the period of the industrial revolution. He demonstrates how craft was invented as industry’s “other”, a necessary counterpart to ideas of progress and upheaval. In the process, the magical and secretive culture of artisans was gradually dominated through division and explication. This left craft with an oppositional stance, a traditional or anti-modern position.

The Invention of Craft ranges widely across media, from lock-making, wood-carving and iron-casting to fashion, architecture and design. It also moves back and forth between periods, from the 18th century to the present day, demonstrating how contemporary practice can be informed through the study of modern craft in its moment of invention.
Street Furniture Design
Authors: Herring Eleanor
Published: July 2017

Eleanor Herring’s unique study of street furniture design in post-war Britain considers how objects which are now familiar parts of our urban environment – lampposts, post boxes, parking meters, litterbins and signage – were designed to populate public spaces. Herring explores the context of a post-war government, backed by various bodies keen to propagate ‘good’ modern design in a Britain whose towns and cities had been laid waste by bombing and the privations of war.

She also considers the innate conservatism of local communities and councils, wary of a standardised street design imposed from above. She traces how the design of street furniture became the site of a fierce struggle which exposed deep-seated anxieties about class, taste and power. Herring’s original research draws upon archival material and on interviews with leading figures in urban design, including the graphic designer Margaret Calvert and industrial designer Kenneth Grange.
Structure And Form In Design
Authors: Hann Michael
Published: July 2017

This book provides a critical examination of structure and form in design, covering a range of topics of great value to students and practitioners engaged in any of the specialist decorative arts and design disciplines. The complexities of two-dimensional phenomena are explained and illustrated in detail, while various three-dimensional forms are also discussed.

In the context of the decorative arts and design, structure is the under lying framework, and form the resultant, visible, two- or three-dimensional outcome of the creative process. Whether hidden or visually detectable in the final design, structure invariably determines whether or not a design is successful in terms of both its aesthetics and its practical performance.

Hann successfully identifies various geometric concepts, and presents and discusses a number of simple guidelines to assist the creative endeavours of both accomplished and student practitioners, teachers and researchers.
Retroperitoneal fibrosis – a report of five cases
Authors: Runowska Marta , Majewski Dominik , Puszczewicz Mariusz
Published: July 2017

Retroperitoneal fibrosis (RPF) is a rare disease, characterized by inflammation and deposition of fibrotic tissue in the vicinity of the abdominal aorta and iliac arteries. We present a report of five patients admitted to our department between January 2014 and February 2017, diagnosed with RPF. Abdominal pain was the most common presenting symptom; however, in one patient, RPF was identified accidentally in routinely performed ultrasonography. In 4 cases, corticosteroids (CS) in combination with azathioprine were applied as first-line therapy, whereas one patient was treated with intravenous methylprednisolone pulses followed by oral CS. In this paper, clinical features as well as laboratory and radiographic findings together with management and treatment outcomes in patients with RPF are discussed. Given the rarity of the condition, it seems important to report every single case of RPF to help establish its management algorithm.
Single Footprint Retrievals for AIRS using a Fast TwoSlab Cloud-Representation Model and All-Sky Radiative Transfer Algorithm
Authors: DeSouza-Machado Sergio , Strow L. Larrabee , Tangborn Andrew , Huang Xianglei , Chen Xiuhong , Liu Xu , Wu Wan , Yang Qiguang
Published: July 2017

Abstract. 1D-variational retrievals of temperature and moisture fields from hyperspectral infrared satellite sounders use cloud- cleared radiances as their observation. These derived observations allow the use of clear-sky only radiative transfer in the inversion for geophysical variables but at reduced spatial resolution compared to the native sounder observations. Cloud-clearing can introduce various errors, although scenes with large errors can be identified and ignored. Information content studies show that when using multi-layer cloud liquid and ice profiles in infrared hyperspectral radiative transfer codes, there are typically only 2–4 degrees of freedom of cloud signal. This implies a simplified cloud representation is sufficient for some applications which need accurate radiative transfer. Here we describe a single-footprint retrieval approach for clear and cloudy conditions, which uses the thermodynamic and cloud fields from Numerical Weather Prediction (NWP) models as a first guess, together with a simple cloud representation model coupled to a fast scattering radiative transfer algorithm (RTA). The NWP model thermodynamic and cloud profiles are first co-located to the observations, after which the N-level cloud profiles are converted to two slab clouds (typically one for ice and one for water clouds). From these, one run of our fast cloud representation model allows an improvement of the a-priori cloud state by comparing the observed and model simulated radiances in the thermal window channels. The retrieval yield is over 90 %, while the degrees of freedom correlate with the observed window channel brightness temperature which itself depends on the cloud optical depth. The cloud representation/scattering package is bench-marked against radiances computed using a Maximum Random Overlap cloud scheme. All-sky infrared radiances measured by NASA's Atmospheric Infrared Sounder (AIRS) and NWP thermodynamic and cloud profiles from the European Center for Medium Range Weather Forecasting (ECMWF) forecast model are used in this paper.
Preindustrial nitrous oxide emissions from the land biosphere estimated by using a global biogeochemistry model

Published: July 2017

Abstract. To accurately assess how increased global nitrous oxide (N2O) emission has affected the climate system requires a robust estimation of the preindustrial N2O emissions since only the difference between current and preindustrial emissions represents net drivers of anthropogenic climate change. However, large uncertainty exists in previous estimates of preindustrial N2O emissions from the land biosphere, while preindustrial N2O emissions on the finer scales, such as regional, biome, or sector scales, have not been well quantified yet. In this study, we applied a process-based Dynamic Land Ecosystem Model (DLEM) to estimate the magnitude and spatial patterns of preindustrial N2O fluxes at the biome, continental, and global level as driven by multiple environmental factors. Uncertainties associated with key parameters were also evaluated. Our study indicates that the mean of the preindustrial N2O emission was approximately 6.20 Tg N yr−1, with an uncertainty range of 4.76 to 8.13 Tg N yr−1. The estimated N2O emission varied significantly at spatial and biome levels. South America, Africa, and Southern Asia accounted for 34.12, 23.85, and 18.93 %, respectively, together contributing 76.90 % of global total emission. The tropics were identified as the major source of N2O released into the atmosphere, accounting for 64.66 % of the total emission. Our multi-scale estimates provide a robust reference for assessing the climate forcing of anthropogenic N2O emission from the land biosphere
Benchmarking Ensemble Streamflow Prediction skill in the UK
Authors: Harrigan Shaun , Prudhomme Christel , Parry Simon , Smith Katie , Tanguy Maliko
Published: July 2017

Abstract. Skilful hydrological forecasts at sub-seasonal to seasonal lead times would be extremely beneficial for decision-making in water resources management, hydropower operations, and agriculture, especially during drought conditions. Ensemble Streamflow Prediction (ESP) is a well-established method for generating an ensemble of streamflow forecasts in the absence of skilful future meteorological predictions, instead using Initial Hydrological Conditions (IHCs), such as soil moisture, groundwater, and snow, as the source of skill. We benchmark when and where the ESP method is skilful across a diverse sample of 314 catchments in the UK and explore the relationship between catchment storage and ESP skill. The GR4J hydrological model was forced with historic climate sequences to produce 51-member ensemble of streamflow hindcasts. We evaluated forecast skill seamlessly from lead times of 1-day to 12-months initialised at the first of each month over a 50-year hindcast period from 1965–2015. Results show ESP was skilful against a climatology benchmark forecast in the majority of catchments across all lead times up to a year ahead, but the degree of skill was strongly conditional on lead time, forecast initialisation month, and individual catchment location and storage properties. UK-wide mean ESP skill decays exponentially as a function of lead time with mean squared error skill scores across the year of 0.839, 0.303, and 0.179 for 1-day, 1-month, and 3-month lead times, respectively. However, skill was not uniform across all initialisation months. For lead times up to 1-month, ESP skill was higher than average when initialised in summer and lower in winter, whereas for longer seasonal and annual lead times skill was highest when initialised in autumn and winter months and lowest in April. ESP is most skilful in the south and east of the UK, where slower responding catchments with higher soil moisture and groundwater storage are mainly located; correlation between catchment Baseflow Index (BFI) and ESP skill was very strong (ρ = 0.896 at 1-month lead time). This is in contrast to the more highly responsive catchments in the north and west which are generally not skilful at seasonal lead times. Overall, this work provides a scientifically defensible justification for when and where use of such a relatively simple forecasting approach is appropriate in the UK and creates a low cost benchmark against which potential skill improvements from more sophisticated hydro-meteorological ensemble prediction systems can be judged.
Debris flow initiation characteristics and occurrence probability after extreme rainfalls: case study in the Chenyulan watershed, Taiwan
Authors: Chen Jinn-Chyi , Jiang Jiang-Guao , Huang Wien-Shun , Tsai Yuan-Fan
Published: July 2017

Abstract. Rainfall and other extreme events often trigger debris flows. This study examines the debris flow initiation characteristics and probability of debris flow occurrence after extreme rainfalls. The Chenyulan watershed, central Taiwan, which has suffered from the Chi-Chi earthquake (CCE) and extreme rainfalls, was selected as a study area. The rainfall index (RI) was used to analyze the return period (T) and characteristics of debris flow occurrence after extreme rainfalls. The characteristics of debris flow occurrence included the variation in critical RI, threshold of RI for debris flow initiation, and recovery period (t0), the time required for the lowered threshold to return to the original threshold. The variations in critical RI after extreme rainfall and t0 associated with RI were presented. The critical RI threshold was reduced in the years following an extreme rainfall event. The reduction in RI as well as t0 were influenced by the RI. Reduced RI values showed an increasing trend over time, and it gradually return to initial RI. The empirical relationship between the probability of debris flow occurrence (P) and corresponding T of the rainfall characteristics for areas affected by extreme rainfalls and affected by the CCE were developed. Finally, a method for determining the P of a rainfall event was proposed based on the relationship between P and T. This method was successfully applied to evaluate the probability of debris flow occurrence after extreme rainfalls.
Dynamical properties and extremes of Northern Hemisphere climate fields over the past 60 years
Authors: Faranda Davide , Messori Gabriele , Alvarez-Castro M. Carmen , Yiou Pascal
Published: July 2017

Abstract. Atmospheric dynamics is described by a set of partial differential equation yielding an infinite dimensional phase space. However, the actual trajectories followed by the system appear to be constrained to a finite dimensional phase space, i.e. a strange attractor. The dynamical properties of this attractor are difficult to determine due to the complex nature of atmospheric motions. A first step to simplify the problem is to focus on observables which affect – or are linked to phenomena which affect – human welfare and activities, such as sea level pressure, near-surface temperature and precipitation. We make use of recent advances in dynamical systems theory to estimate two instantaneous dynamical properties of the above fields for the Northern Hemisphere: local dimension and persistence. We then use these metrics to characterise the seasonality of the different fields and their interplay. We further analyse the large-scale anomaly patterns corresponding to phase-space extremes – namely timesteps at which the fields display extremes in their instantaneous dynamical properties. The analysis is based on the NCEP/NCAR reanalysis data, over the period 1948–2013. The results show that: (i) despite the high dimensionality of atmospheric dynamics, the Northern Hemisphere sea level pressure and temperature fields can on average be described by roughly twenty degrees of freedom; (ii) the precipitation field has a higher dimensionality; (iii) the seasonal forcing modulates the variability of the dynamical indicators and affects the occurrence of phase-space extremes. We further identify a number of robust correlations between the dynamical properties of the different variables.
Quantifying thermohaline circulations: seawater isotopic compositions and salinity as proxies of the ratio between advection time and evaporation time
Authors: Berman Hadar , Paldor Nathan , Lazar Boaz
Published: July 2017

Abstract. Uncertainties in quantitative estimates of the thermohaline circulation in any particular basin are ‎large, partly due to large uncertainties in quantifying excess evaporation over precipitation and ‎surface velocities. A single nondimensional parameter, ‎γ ≡ q⁄h x⁄u is proposed to characterize the ‎‎strength of the thermohaline circulation by combining the physical parameters of surface ‎velocity (u), evaporation rate (q), mixed layer depth (h) and trajectory length (x). Values of γ can ‎be estimated directly from cross-sections of salinity or seawater isotopic composition (δ18O and δD). Estimates of ‎γ in the Red Sea and the South-West Indian Ocean are 0.1 and 0.02, ‎respectively, which implies that the thermohaline contribution to the circulation in the former is ‎higher than in the latter. Once the value of ‎γ has been determined in a particular basin, either q ‎or u can be estimated from known values of the remaining parameters. In the studied basins ‎such estimates are consistent with previous studies. ‎
Do you hear me? Student voice, academic success and retention
Authors: Allen Jennifer , Nichols Catherine
Published: July 2017

The place of student voice, whilst present in the evaluation of the teaching and learning process in higher education institutions, is limited in the planning, provision and ownership of student support services that promote student success and retention. This project seeks to recognise that students have an active role and partnership in constructing their own success and their voice is integral to this partnership. To promote the importance of the student voice at the University of Newcastle (UON), this initiative has established the Office of Student Advocacy (OSA). This is a collaborative enterprise between university staff and student associations, a communication strategy for student-elected representatives on university committees and, a reporting mechanism for student concerns to be communicated to the relevant decision makers at UON. The project repositions students as co-creators of student support to inform student success.

A amostra foi constituída por 100 sujeitos de ambos os sexos que se encontravam no último ano do curso. Foram empregados os questionários Perceptions of Youth Obesity and Physical Education Questionnaire e The Antifat Attitudes Scale. Os acadêmicos reconhecem as consequências da obesidade para a saúde e qualidade de vida e apontam a escola e as aulas de Educação Física como um espaço privilegiado de intervenção para o seu controle. No entanto, os participantes da pesquisa mostraram-se avessos à possibilidade de uma conversão total da Educação Física escolar para essa finalidade.

Resumo: Trata do tema da educação para a saúde em escolas públicas no município de Vitória/ES a partir do Programa Saúde na Escola (PSE) e suas relações com a Educação Física (EF). Um levantamento revelou a inexistência de projetos sobre o tema da saúde vinculados à EF. Isso ensejou o desenvolvimento de um projeto de formação continuada com seis professores de EF desta rede, a partir dos princípios da pesquisa-ação. De acordo com os dados produzidos e apesar da EF não ser citada diretamente nos documentos do PSE, existem potenciais relações a serem desenvolvidas. Contudo, há pouca clareza por parte dos profissionais da educação e da saúde sobre como implementá-lo, o que indica a necessidade de formações que capacitem esses agentes a desenvolverem as ações previstas no programa.

PHYSICAL EDUCATION OF RELATIONSHIPS BRAZILIAN’S SCHOOL HEALTH PROGRAM: VISIONS OF TEACHERS OF VITÓRIA/ES SCHOOLS Abstract: Addresses the topic of education for health in public schools in the city of Vitória/ES, the Brazilian’s School Health Program (PSE) and its relationship to Physical Education (PE). A survey showed that no projects on the theme of health related to PE. This gave origin to a continued formation project with six PE teachers of this network, from the action research principles. According to the data produced despite the PE not be cited directly into the PSE documents, there are potential relationships to be developed. However, there is little clarity on the part of professionals in education and health on how to implement it. Which indicates the need for formations that empower these agents to develop the actions planned in the program. Keywords: School Health. Health Promotion. Physical Education and Training.

O texto objetiva analisar como o ato reflexivo contribui para a articulação entre os saberes profissionais e experienciais de professoras de Educação Física ao ministrar o conteúdo dança em sua prática pedagógica. A pesquisa colaborativa acompanhou três professoras, da rede municipal de ensino, integrantes do Projeto Dança na escola. Utilizaram-se 6 técnicas de coleta: narrativa de formação; 6 seminários temáticos, com 4 grupos focais, 10 laboratórios, 10 autorreflexões, 10 vídeos etnográficos e a sessão reflexiva coletiva. A analise foi a hermenêutica dialética (RICŒUR, 1978). O estudo revela que o ato reflexivo minimizou o nível de “inconsciência” no ato pedagógico e ampliou as capacidades das professoras atuarem como pesquisadores em suas práticas cotidianas.
A CONSTRUÇÃO DA AUTONOMIA NAS AULAS DE EDUCAÇÃO FÍSICA: APLICAÇÃO E AVALIAÇÃO DE UMA PROPOSTA PEDAGÓGICA
Authors: Molina Flaviana Fellegger , Freire Elisabete Dos Santos , Miranda Maria Luiza De Jesus
Published: July 2017

O objetivo deste estudo foi analisar a aplicação de uma proposta pedagógica para estimular a autonomia nas aulas de Educação Física e identificar a perspectiva de uma professora e de seus estudantes sobre a proposta aplicada. Foram utilizados como instrumentos a observação, o questionário e a entrevista. A proposta aplicada estimulou a reflexão, a compreensão crítica e a competência dialógica dos estudantes. Entretanto, foram percebidas algumas dificuldades enfrentadas pela professora, como o controle de sua ansiedade, a tendência ao autoritarismo e a construção de expectativas irreais. Além disso, a avaliação do envolvimento do estudante precisa ser aperfeiçoada. Novas pesquisas podem contribuir para compreender a origem e as formas de superar as dificuldades identificadas.

O objetivo deste estudo foi verificar o que causa medo nos praticantes de natação e identificar o que eles fazem para superar esse sentimento. A amostra foi composta por 18 alunos iniciantes de natação, com média de idade de 29,72 ± 9,70 anos. O instrumento utilizado foi um questionário e para análise dos dados foi utilizada a estatística descritiva, e o método do “Discurso do Sujeito Coletivo” (DSC). Identificou-se que a imersão, a saída (mergulho), a falta de prática, os traumas, causam medo em alguns alunos. Para superar o medo, realizam técnicas de respiração e tentam executar o movimento que sentem medo. Compreender o medo do aluno pode auxiliar aos profissionais no estabelecimento de direcionamentos didáticos para a aprendizagem da natação.

O objetivo deste trabalho é analisar narrativas midiáticas sobre a temática Olímpica a partir de reportagens da Revista Veja de 1968 a 1996. Para tanto, utilizou-se como técnica a análise de conteúdo. Os seguintes eixos temáticos foram identificados e discutidos a partir das narrativas:1) "ser olímpico" - referindo-se ao sentido da participação "amadora" dos brasileiros; 2) o clamor por atletas competitivos - corresponde à cobrança por uma melhor organização e resultados esportivos; 3) de "indigentes" a heróis olímpicos - narrativas que apontam a mudança de papel na participação dos brasileiros, enfatizando os bons resultados.

Resumo: O projeto “Os 11 pela Saúde” trata-se de uma iniciativa da FIFA, desenvolvido nas aulas de Educação Física em algumas das cidades-sede da Copa do Mundo. Desta forma, este artigo apresenta um estudo documental que teve o objetivo de analisar o projeto da FIFA “Os 11 pela Saúde” para identificar como são abordadas as áreas da saúde, educação, esporte e lazer. Percebeu-se que o projeto tem uma perspectiva higienista e algumas das suas perspectivas não condiz com a realidade brasileira. Observou-se que é necessário um diálogo mais próximo entre os organizadores do projeto, professores de Educação Física, escola e a comunidade em geral, para que valores como saúde, educação, esporte e lazer sejam concretizados a partir das fragilidades e interesses da população. Palavra-chave: Atividades de lazer. Educação Física. Esporte.

Nos tempos atuais das Tecnologias da Informação e da Comunicação (TICs) é possível que a escola possa ser um local adequado para a apropriação esclarecida e criativa dos Jogos Eletrônicos (JEs). O objetivo desta pesquisa foi identificar o perfil do uso de TICs por alunos do ensino fundamental e verificar a relação entre os valores percebidos por estes alunos na prática de JEs com os valores desenvolvidos nas aulas de Educação Física. Um questionário validado por dois professores doutores de Educação Física e dois especialistas na área Informática foi aplicado a 348 alunos.  Os resultados indicaram a inserção do uso TICs na cultura dos alunos, e os valores percebidos por esses alunos na prática dos JEs se coadunaram com os valores do esporte desenvolvidos na prática da Educação Física.  Os resultados parecem sugerir uma possibilidade de desenvolver valores do esporte integrando a prática da Educação Física com JEs constituintes da cultura desses alunos.

O objetivo foi analisar a produção científica sobre insatisfação corporal e comportamentos de risco para transtornos alimentares em adolescentes atletas de esportes estéticos. Foram analisados 45 estudos publicados entre 2008 e 2015. No Brasil, foram identificadas prevalências semelhantes de insatisfação corporal e comportamento de risco para transtorno alimentar em atletas, possivelmente pela utilização dos mesmos instrumentos de avaliação. Internacionalmente, identificou-se maior variedade de instrumentos avaliativos, o que repercutiu nas diferenças das prevalências desses comportamentos. São incentivados estudos brasileiros que utilizem métodos longitudinais e com grupo controle
