Teeth morphology and dental sexual dimorphism of three species of the sandskate genus Psammobatis Günther, 1870 from the Brazilian coast (Rajiformes, Arhynchobatidae)
Authors: Brum-Neto Alvaro , Lucena Carlos Alberto Santos de
Published: May 2020

Conjuntos de mandíbulas das raias Psammobatis extenta (n = 10), P. lentiginosa (apenas indivíduos adultos, n = 8) e P. rutrum (apenas indivíduos adultos, n = 10) foram examinados utilizando microscopia eletrônica de varredura. Os dentes das fêmeas das três espécies e os dos imaturos de P. extenta não apresentaram diferenças, todos com dentes esmagadores monocuspidados, com uma cúspide pequena ou ausente. A heterodontia monognática foi observada em espécimes adultos de ambos os sexos das três espécies analisadas. Espécimes imaturos de P. extenta e fêmeas das três espécies diferiram dos machos adultos por ter dentes esmagadores ao invés dos dentes agarradores dos machos, indicando heterodontia sexual. Os dentes dos machos de P. extenta são pontiagudos e bem pronunciados, com as cúspides arredondadas, enquanto os machos de P. rutrum e P. lentiginosa possuem cúspides elípticas e similares entre si. Espécimes imaturos de P. extenta possuem cúspides pequenas. Os dentes de P. lentiginosa apresentam um sulco longitudinal em sua face labial, um caráter aqui hipotetizado como uma condição derivada.
Pescadores e aves marinhas: etnobiologia de uma comunidade pesqueira no sul do Brasil
Authors: Mazzochi Mariana Scain , Carlos Caio José
Published: May 2020

Comunidades dependentes de recursos pesqueiros combinam informações acerca do comportamento da ictiofauna com características oceanográficas e interações ecológicas. Esse conhecimento é definido como tradicional: um complexo entre conhecimento histórico, prático e crenças, os quais evoluem por processos adaptativos e são transmitidos através das gerações. No litoral norte do Rio Grande do Sul, uma comunidade estabelecida nas margens do Rio Tramandaí realiza pesca de emalhe. A interação com animais marinhos ocorre em todas as artes de pesca na região, e a captura incidental de aves marinhas é registrada no sul do país. Predadoras de topo, as aves interagem com barcos pesqueiros em busca de alimento. O objetivo do presente estudo é explorar o conhecimento dos pescadores sobre as aves marinhas. Doze pescadores de Imbé foram entrevistados. Nas narrativas escritas, utilizou-se a análise de discurso. Os pescadores identificam as espécies de aves e as relacionam ao ambiente, reconhecem seus ciclos de vida, e utilizam seus comportamentos para localizar o recurso pesqueiro e obter dados oceanográficos e meteorológicos para aprimorar a navegação. Dessa forma, verificou-se que o conhecimento sobre as aves é uma variável para a orientação no oceano e para a realização de uma pesca efetiva.
Richard Bean’s The Big Fellah (2010) and Jez Butterworth’s The Ferryman (2017): two plays about the Northern Troubles from outside of Northern Ireland
Authors: Mikami Hiroko
Published: May 2020

During the three decades of the Troubles of Northern Ireland (1969-1998), a remarkable amount of plays about the Troubles was written and almost of them, it seems, had been ‘monopolised’ by (Northern) Irish playwrights. Recently, however, certain changes about this monopoly have been witnessed and those who do not claim themselves as Irish descendants have begun to choose the Northern Troubles as their themes. Also, there have been growing concerns about violence worldwide since 9.11. This article deals with two plays, Richard Bean’s The Big Fellah and Jez Butterworth’s The Ferryman, neither of which was written by an Irish playwright and examines whether and to what extent it is possible to say that they can transcend regional boundaries and become part of global memories in the context of the post-Good Friday Agreement and the post 9.11.

Roger Casement in the twenty-first century: the public and private faces of a multi-media Irish hero
Authors: Nunez Domingos , Harris Peter James
Published: May 2020

Sir Roger Casement (1864-1916) was a diplomat in the British Colonial Service and an Irish nationalist who was hanged for high treason in London in 1916. This article offers a critical overview of the material that has been published about Casement's humanitarian work in the Congo and the Peruvian Amazon and his trial in London, including biographies and editions of his own journals, particularly the so-called Black Diaries, as well as the various dramatisations of this material for the stage and other media, concentrating on those produced in the twenty-first century. The second part of the article consists of the playwright’s account of the writing of As Duas Mortes de Roger Casement, which received its premiere in São Paulo in 2016, commenting on the play’s relationship to its sources and the decisions that were taken in the creative process.
Cultural appropriation: brazilian stage productions of Samuel Beckett’s Waiting for Godot
Authors: Camati Anna Stegh
Published: May 2020

The present article aims at discussing, first and briefly, the experimental features Samuel Beckett (1906-1989) imprinted in Waiting for Godot (1948-1949), among them the implosion of dramatic elements and the inscription of detailed performance instructions within the text itself, thus creating a performance model for which he used to demand respect. Thereupon, after addressing the 1955 first incursion of Godot in Brazil, a historical panorama of some outstanding stage productions of the play, mainly in terms of conceptualization and critical reception, will be provided, in the light of theoretical perspectives by Oswald de Andrade, José Roberto O’Shea, Patrice Pavis, Peter Burke, among others.
Domesticity in the trilogies of Sean O’Casey and Yu Ch'i-jin
Authors: Hwang Ji Hyea
Published: May 2020

This article examines Sean O’Casey and Yu Ch’i-jin’s portrayal of the domestic realm in the Dublin Trilogy of the 1920s and Nongchon Trilogy of the 1930s, respectively. Yu is indebted to O’Casey for his themes and style in playwrighting, for he saw O’Casey’s works as models for his own dramatic depictions of colonial Korea. A close study of Yu’s approach and the two trilogies reveal that his “deep-rooted admiration” for O’Casey does not indicate Yu’s aims to Westernize Korean theatre, but rather reveals his desire to impact the Korean audiences with realistic depictions of their everyday struggles. Using Lionnet and Shih’s idea of “minor transnationalism,” I argue that this lateral relationship is an instance of transcolonial solidarity in which Yu echoes O’Casey’s methodology to contribute to establishing a national theatre and drama tradition as did O’Casey to the Abbey Theatre.
Practical Aesthetics
Authors: Bennett Jill
Published: May 2020

Practical Aesthetics brings a pursuit, long seen as rarefied and indulgent, out of the ivory tower and down to Ground Zero. Theoretically ambitious, fiercely original, it is a radical new account of art's rootedness in the social world and of the value of aesthetics to contemporary society. Beginning with the cultural watershed of 9/11, internationally-renowned scholar Jill Bennett explores artistic developments in relation to current events to argue that understanding aesthetics is as vital to social and political theory as it is to the arts. Taking as its starting-point a definition of art as the critical, self-conscious manipulation of media, Bennett examines a wide range of events from the "War on Terror" to the football World Cup to elucidate how aesthetic perception works in a social field, a process that begins with the rich emotional content of the visual imagery with which we are constantly bombarded. Now more than ever, Bennett argues, understanding how what we see informs what we do is not merely an artistic endeavour but one which is fundamental to our very being.

Part of the Radical Aesthetics, Radical Art series, this book challenges the notion that art and 'real life' are somehow opposed. Practical Aesthetics proposes a new way of reading contemporary artworks - and a new understanding of how fundamental art is to our social survival.
Guattari Reframed
Authors: Elliott Paul
Published: May 2020

Guattari Reframed presents a timely and urgent rehabilitation of one of the twentieth century’s most engaged and engaging cultural philosophers. Best known as an activist and practising psychiatrist, Guattari’s work is increasingly understood as both eerily prescient and vital in the context of contemporary culture. Employing the language of visual culture and concrete examples drawn from it, this book introduces and reassesses the major concepts developed throughout Guattari’s writings and his call to transform the deadening homogeneity of contemporary existence into the ‘universe of creative enchantments’. Paul Elliott asserts the significance of Guattari as a revolutionary philosopher and cultural theorist, and invites the reader to transform both their understanding of his work and their lives through his ideas.
Derrida Reframed
Authors: Richards K Malcolm
Published: May 2020

Are your students baffled by Baudrillard? Dazed by Deleuze? Confused by Kristeva? Other beginners’ guides can feel as impenetrable as the original texts to students who ’think in images’. “Contemporary Thinkers Reframed” instead uses the language of the arts to explore the usefulness in practice of complex ideas. Short, contemporary and accessible, these lively books utilise actual examples of artworks, films, television shows, works of architecture, fashion and even computer games to explain and explore the work of the most commonly taught thinkers. Conceived specifically for the visually minded, the series will prove invaluable to students right across the visual arts. ‘Deconstruction’ is touted in every visual area from architecture to fashion, yet few really understand what Derrida’s notorious concept means, much less his elusive idea of ‘differance’. In fact Derrida’s work can seem almost impenetrable.

This guide explains Derrida’s key concepts through examples from across the whole spectrum of the arts, looking at the work of architects such as Bernard Tschumi and Daniel Libeskind, fashion designers such as Ann Demeulemeister and at the work of artists as varied as Kara Walker, Yinka Shonibare MBE, Rachel Whiteread and Jeff Wall. Showing what Derrida’s work really ‘means’ in practice, this short guide makes this thinker’s complex work accessible to a wider public.
Sex: Antiquity and its Legacy
Authors: Orrells Daniel
Published: May 2020

Sex is fundamental to society. We cannot think about politics, power, identity or culture without also thinking about sexuality. Despite this, the scientific study of sexual behaviour is a relatively recent phenomenon. Doctors, legal experts and other intellectuals have all pondered challenging questions in an attempt to stay abreast of the latest sexual research. How might we separate talking about sex scientifically from discussing and consuming pornography? How do we speak objectively about desire and pleasure? And how do the words that we use to talk about sex affect what we are able to say about it? Such questions increasingly inform public discourse across a variety of media. Showing how ancient words and ideas have left a significant imprint on present-day ideas about sex, Daniel Orrells offers abold new narrative of how the scientific study of sexuality came into being.

Uncovering the intriguing story of how the obscene and erotic verse of Roman epigram and love poetry became the sanitised language of nineteenth-century sexual science, this divertingly readable book demonstrates how the reception of both Latin and Greek texts was central to the development of modern sexology and psychoanalysis. Ranging from Sappho, Catullus and Martial to Michel Foucault, Richard von Krafft-Ebing and Sigmund Freud, the author reveals just how profoundly classics has shaped the landscape of sexual identity that we inhabit today.
Immersion and Participation in Punchdrunk’s Theatrical Worlds
Authors: Westling Carina E. I.
Published: May 2020

Longlisted for the PQ Best Publication Award in Performance Design & Scenography 2023

Immersion and Participation in Punchdrunk’s Theatrical Worlds is a detailed account of the company's award-winning productions and their historical context. Examining Punchdrunk's role as pioneers of immersive theatre in the UK through a range of their productions including Sleep No More and The Drowned Man besides theatrical works such as Faust, The Duchess of Malfi and Kabeiroi, and cross-platform productions like The Moon Slave, The Borough and The Oracles, the book presents an original framework for understanding immersion in theatrical and mixed reality experiences.

Central to the book is a study of how immersive experience is produced in interaction with physical and digital scenography for participatory audiences. Through ethnographies of the company, their designers, actors, producers and audiences, the book interrogates the relationship between the aesthetics of interaction and the experience of immersion in Punchdrunk’s work. The theoretical framework that the book introduces affords analyses of material cultures and the influence of technology on interaction design in theatre and beyond, and offers a blueprint for next-generation immersive design and scenography for interactive multimedia environments.
Harrison Ford
Authors: Luzón-Aguado Virginia
Published: May 2020

Harrison Ford is known for such iconic roles as Han Solo, Indiana Jones and Rick Deckard – but his career of 50 years (and counting) encompasses a plethora of other thought-provoking roles. His off-screen persona has been no less intriguing. Covering a wide timespan, this book assesses Harrison Ford as ‘star’ from the difficult Hollywood studio years where he began, his blockbusters of the 1980s, through to the impact of ageist culture on his artistry of recent years.

The author argues that Ford has generally been seen as a potent, irresistible combination of tradition and modernity. He is an actor who both reflects and utilises changing ideas about American masculinity in the context of Hollywood film production: particular male types are revealed as much in his trademark trustworthy hero act as in his more fallible, less conservative and therefore commercially riskier characters. Luzon Aguado explores these particular star identities and every fluctuation in between. She gives due attention to his much-neglected acting abilities while examining the crucial interplay between star persona and the constraints and conventions of genre. Going beyond standard accounts of Ford's production and pinpointing overlooked aspects of his work, and the creation of the star through cultural artefacts like magazine interviews and advertising campaigns, this book reveals the depth and dimensions of the enduring American screen legend that is Harrison Ford.
Selling Out
Authors: Klein Bethany
Published: May 2020

The relationship between popular music and consumer brands has never been so cosy. Product placement abounds in music videos, popular music provides the soundtrack to countless commercials, social media platforms offer musicians tools for perpetual promotion, and corporate-sponsored competitions lure aspiring musicians to vie for exposure. Activities that once attracted charges of ‘selling out’ are now considered savvy, or even ordinary, strategies for artists to be heard and make a living. What forces have encouraged musicians to become willing partners of consumer brands? At what cost? And how do changes in popular music culture reflect broader trends of commercialization?

Selling Out traces the evolution of ‘selling out’ debates in popular music culture and considers what might be lost when the boundary between culture and commerce is dismissed as a relic.

Secondary ice production in summer clouds over the Antarctic coast: an underappreciated process in atmospheric models
Authors: Sotiropoulou Georgia , Vignon Etienne , Young Gillian , Morrison Hugh , O'Shea Sebastian J. , Lachlan-Cope Thomas , Berne Alexis , Nenes Athanasios
Published: May 2020

Abstract. The correct representation of Antarctic clouds in atmospheric models is crucial for accurate projections of the future Antarctic climate. This is particularly true for summer clouds which play a critical role in the surface melting of the ice-shelf in the vicinity of Weddell Sea. However these clouds are often poorly represented, as ice crystal number concentrations (ICNCs) are undepredicted by atmospheric models, even when primary ice formation is constrained with aerosol measurements. Rime-splintering, thought to be the dominant secondary ice production (SIP) mechanism at temperatures between −8 and −3 °C, is also very weak in summer Antarctic conditions. Including a parameterization for SIP due to break-up (BR) from collisions between ice particles in the Weather and Research Forecasting model bridges the gap between observations and simulations, suggesting that BR could account for the enhanced ICNCs in the pristine Antarctic atmosphere. These results are insensitive to uncertainties in primary ice production. The BR mechanism is currently not represented in most weather prediction and climate models; including this process can have a significant impact on the Antarctic radiation budget and thus in projections of the future regional climate.
A daily, 250 m, and real-time gross primary productivity product
(2000–present) covering the Contiguous United States
Authors: Jiang Chongya , Guan Kaiyu , Wu Genghong , Peng Bin , Wang Sheng
Published: May 2020

Abstract. Gross primary productivity (GPP) quantifies the amount of carbon dioxide (CO2) fixed by plants through photosynthesis. Although as a key quantity of terrestrial ecosystems, there is a lack of high-spatial-and-temporal-resolution, real-time, and observation-based GPP products. To address this critical gap, here we leverage a state-of-the-art vegetation index, near‐infrared reflectance of vegetation (NIRV), along with accurate photosynthetically active radiation (PAR), to produce a SatelLite Only Photosynthesis Estimation (SLOPE) GPP product in the Contiguous United States (CONUS). Compared to existing GPP products, the proposed SLOPE product is advanced in its spatial resolution (250 m versus > 500 m), temporal resolution (daily versus 8-day), instantaneity (1 day latency versus > 2 weeks latency), and quantitative uncertainty (on a per-pixel and daily basis versus no uncertainty information available). These characteristics are achieved because of several technical innovations employed in this study: (1) SLOPE couples machine learning models with MODIS atmospheric and land products to accurately estimate PAR. (2) SLOPE couples highly efficient and pragmatic gap-filling and filtering algorithms with surface reflectance acquired by both Terra and Aqua MODIS satellites to derive a soil-adjusted NIRV (SANIRV) dataset. (3) SLOPE couples a temporal pattern recognition approach with a long-term Crop Data Layer (CDL) product to predict dynamic C4 crop fraction. Through developing a parsimonious model with only two slope parameters, the proposed SLOPE product explains 84 % of the spatial and temporal variations in GPP acquired from 50 AmeriFlux eddy covariance sites (332 site-years), with a root-mean-square error (RMSE) of 1.65 gC m−2 d−1. With such a satisfactory performance and its distinct characteristics in spatiotemporal resolution and instantaneity, the proposed SLOPE GPP product is promising for regional carbon cycle research and a broad range of real-time applications. The archived dataset is available at https://doi.org/10.3334/ORNLDAAC/1786 (Download page: https://daac.ornl.gov/daacdata/cms/SLOPE_GPP_CONUS/data/) (Jiang and Guan, 2020), and the real-time dataset is available upon request.
Using Radar Observations to Evaluate 3D Radar Echo Structure
Simulated by a Global Model
Authors: Wang Jingyu , Fan Jiwen , Houze Jr. Robert A. , Brodzik Stella R. , Zhang Kai , Zhang Guang J. , Ma Po-Lun
Published: May 2020

Abstract. The Energy Exascale Earth System Model (E3SM) developed by the Department of Energy has a goal of addressing challenges in understanding the global water cycle. Success depends on correct simulation of cloud and precipitation elements. However, lack of appropriate evaluation metrics has hindered the accurate representation of these elements in general circulation models. We derive metrics from the three-dimensional data of the ground-based Next generation radar (NEXRAD) network over the U.S. to evaluate both horizontal and vertical structures of precipitation elements. We coarsened the resolution of the radar observations to be consistent with the model resolution and improved the coupling of the Cloud Feedback Model Intercomparison Project Observation Simulator Package (COSP) and E3SM Atmospheric Model Version 1 (EAMv1) to obtain the best possible model output for comparison with the observations. Three warm seasons (2014–2016) of EAMv1 simulations of 3D radar reflectivity features at an hourly scale are evaluated. A general agreement in domain-mean radar reflectivity intensity is found between EAMv1 and NEXRAD below 4 km altitude; however, the model underestimates reflectivity over the central United States, which suggests that the model does not capture the mesoscale convective systems that produce much of precipitation in that region. The shape of the model estimated histogram of subgrid scale reflectivity is improved by correcting the microphysical assumptions in COSP. The model severely underestimates radar reflectivity at upper levels – the simulated echo top height is about 4 km lower than in observations – and this result is not changed by tuning any single physics parameter.
GRAINet: Mapping grain size distributions in river beds from UAV
images with convolutional neural networks
Authors: Lang Nico , Irniger Andrea , Rozniak Agnieszka , Hunziker Roni , Wegner Jan Dirk , Schindler Konrad
Published: May 2020

Abstract. Grain size analysis is the key to understand the sediment dynamics of river systems. We propose GRAINet, a data-driven approach to analyze grain size distributions of entire gravel bars based on georeferenced UAV images. A convolutional neural network is trained to regress grain size distributions as well as the characteristic mean diameter from raw images. GRAINet allows the holistic analysis of entire gravel bars, resulting in (i) high-resolution maps of the spatial grain size distribution at large scale, and (ii) robust grading curves for entire gravel bars. To collect a large training dataset of 1,491 samples, we introduce digital line sampling as a new annotation strategy, following the widely applied line sampling analysis of Fehr (1987). Our evaluation on 25 gravel bars along 6 different rivers in Switzerland yields high accuracy: The resulting maps of mean diameters have a mean absolute error of 1.1 cm, with no bias. Robust grading curves for entire gravel bars can be extracted if representative training data is available. At the gravel bar level the MAE error of the predicted mean diameter is even reduced to 0.3 cm. Extensive experiments were carried out to study the quality of the digital line samples, the generalization capability of GRAINet to new locations, the model performance w.r.t. human labeling noise, the limitations of the current model, and the potential of GRAINet to analyze images with low resolutions.
Mountain waves impact wind power generation

Published: May 2020

Abstract. Large mountains can modify the weather downstream of the terrain. In particular, when stably stratified air ascends a mountain barrier, buoyancy perturbations develop. These perturbations can trigger mountain waves downstream of the mountains that can reach deep into the atmospheric boundary layer where wind turbines operate. Several such cases of mountain waves occurred during the Second Wind Forecast Improvement Project (WFIP2) in the Columbia Basin in the lee of the Cascade Mountains bounding the states of Washington and Oregon in the Pacific Northwest of the United States. Signals from the mountain waves appear in boundary-layer sodar and lidar observations as well as in nacelle wind speeds and power observations from wind plants. Weather Research and Forecasting model simulations also produce mountain waves. Even small oscillations in wind speed caused by mountain waves can induce oscillations between full rated power of a wind farm and half of the power output, depending on the position of the mountain wave's crests and troughs. This paper aims at understanding how mountain waves form in the complex terrain of the Columbia Basin, subsequently affect wind energy production, and impact aspects of operational forecasting, wind power plant layout, and integration of power into the electrical grid.
Narratives of Access: A Critical Exploration of How Institutional Interactions with Students Affect Regional Student Participation in Higher Education
Authors: Ostini Jenny , Partridge Helen , Kelly Kate , Owen Sue , Jeffries Sandra
Published: May 2020

This article examines the narratives that drive university staff understanding of the concerns and experiences of regional and remote students at five universities in Australia. Interviews were conducted with thirty university staff members over a period of three months in 2018. Reflexive thematic analysis of the stories told by staff of supporting regional students found that staff used the lens of access to create meaningful stories for themselves and others in how they supported students. Access is defined as a multi-faceted term encompassing access to people, Internet, study materials and equipment and study environments. Access is facilitated by a sense of belonging or identity as a student and limited by the lack of this. Our analysis of “belongingness” draws on Bourdieu’s concepts of habitas to start to unpick the interactions between higher education institutions and the student that develop student identities as scholars and centres the narrative on the student as a person, wrestling to gain many forms of access within complex social situations.
Maternidad y situación sin hogar: Diferencias entre mujeres madres y no madres en situación sin hogar
Authors: Piqueras Lapuente Susana , Panadero Herrero Sonia , Vázquez Cabrera José Juan
Published: May 2020

Este artículo  proporciona una descripción de las características diferenciales entre  mujeres en situación sin hogar que son madres de hijos/as menores con respecto a mujeres en esa misma situación y que no lo son en la ciudad de Madrid. Para ello se utilizó una metodología cuantitativa con una muestra de 92 mujeres en situación sin hogar. En los resultados encontrados se aprecian diferencias entre ambos grupos de mujeres indicando un mayor deterioro para aquellas que son madres de hijos/as menores. Los datos mostraron que más del 40% de estas mujeres en situación sin hogar tenían hijos/as menores en el momento de realizar la entrevista y confirmaron la existencia de diferencias entre las mujeres que eran madres de hijos/as menores y las mujeres en su misma situación que no eran madres, como por ejemplo: el nivel educativo, el lugar de alojamiento en el último mes, tiempo en situación sin hogar o en el número de sucesos vitales estresantes. Por otra parte estos resultados son novedosos en nuestro país  porque ha diferenciado a dos grupos claves de mujeres en situación sin hogar que no han sido objeto de estudio hasta el momento: aquellas con hijos/as menores y sin hijos.
Maternidades en tensión. Entre la maternidad hegemónica, otras maternidades y no-maternidades
Authors: Bogino Larrambebere Mercedes
Published: May 2020

Este artículo propone repensar la “maternidad hegemónica” en las sociedades contemporáneas a partir de la emergencia de experiencias culturalmente descuidadas y políticamente desprotegidas como las “no-maternidades” u “otras maternidades”. Para ello, se plantea un análisis de las distintas interpretaciones que sitúan la maternidad en el centro del debate feminista y se enfatiza la presencia de aquellas figuras tradicionalmente periféricas. De este modo, en primer lugar, se traza una genealogía de la “maternidad hegemónica” en las sociedades occidentales a través de la producción intelectual de autoras clásicas feministas. En segundo lugar, desde diferentes aproximaciones antropológicas, se presenta la categoría de “otras maternidades” como experiencias que crean nuevas formas de parentesco y modelos de familia cuestionando así el ideal de la maternidad biológica y la familia bio-conyugal. En este sentido, se destaca la necesidad de desagregar la maternidad como vínculo aparentemente indisociable entre el material genético, el cuerpo gestante, la filiación y la crianza. En tercer lugar, se reflexiona sobre la categoría de “no-maternidades”, recurriendo a enfoques interdisciplinares que ponen de manifiesto la existencia de experiencias contrahegemónicas donde se expresan diversas formas de resistencia, transgresión o rebeldía, esto es, distintas formas de reivindicar la autonomía reproductiva, el tiempo propio y la creatividad. Así pues, en este artículo, a través del replanteamiento de la maternidad como categoría compleja, no vinculada en exclusiva a la experiencia biológica ni meramente como un mandato social, se ha pretendido realizar una aportación al debate sobre la “diversidad reproductiva”, subrayando el derecho de las mujeres a elegir sin presiones ni prejuicios.

Background/Aims: Exclusive enteral nutrition (EEN), an established modality for pediatric Crohn’s disease (CD) is seldomly utilized in adults. The present study reports the outcome of EEN in adult CD patients at a tertiary care hospital in India.Methods: This was a retrospective analysis of CD patients who received EEN as a sole modality/adjunct to other treatment. The primary and secondary outcomes changed in Crohn’s Disease Activity Index (CDAI), and clinical response (decline in CDAI > 70), respectively, at 4 and 8 weeks. Subgroup analysis evaluated response across different phenotypes, EEN formulations and prior treatment. Linear mixed effect model was created to assess the predictors of EEN response.Results: Thirty-one CD patients received EEN over median duration of 4 weeks (range, 2–6 weeks). CDAI showed a significant improvement post EEN at 4 (baseline 290 [260–320] vs. 240 [180–280], P= 0.001) and 8 weeks (baseline 290 [260–320] vs. 186 [160–240], P= 0.001), respectively. The cumulative clinical response rates at 4 and 8 weeks were 37.3% and 80.4% respectively. The clinical response rates at 8 weeks across B1 (n = 4), B2 (n = 18) and B3 (n = 9) phenotypes were 50%, 78.8% and 100% respectively (log-rank test, P= 0.093). The response rates at 8 weeks with polymeric (n = 8) and semi-elemental diet (n = 23) were 75% and 82.6%% respectively (log-rank test, P= 0.49). Baseline CDAI (odds ratio, 1.008; 95% confidence interval, 1.002–1.017; P= 0.046) predicted response to EEN.Conclusions: EEN was effective in inducing clinical response across different phenotypes of CD. Baseline disease activity remained the most important predictor of clinical response to EEN.
Three Decades Monitoring of Shoreline Change Pattern of Damietta Promontory, Nile Delta, Egypt
Authors: El-Gamal Ayman A. , Balbaa Sherif H. , Rashed Mohamed A. , Mansour Ahmed S.
Published: May 2020

The Nile Delta is located on the Egyptian Mediterranean coast extending along nearly 240 km from the east of Alexandria to Port Said. The coastal area of the Nile Delta Promontories has been suffering extensive erosion problem. This was achieved after the construction of many water regulation structures in Nile River as dams and barrages, particularly the Aswan High Dam. It has nearly stopped the sediment flux carried by the Nile River to the Delta. This process has caused the Mediterranean Sea to reshape the Nile Delta coastal area. In order to cease these problems several engineering hard structures have been built. These structures avoided in ceasing the problem in the site of construction but shifted the erosion problem to the adjacent sites. This study aimed to analyze the shoreline change pattern on the term of three decades during the period between 1985 to 2015 at the coastal strip of Damietta Promontory and the impact of these protective structures on the coastal area. This was accomplished by the automated delineation of the successive shorelines covering this period using remote sensing imagery. The shorelines were extracted using the MNDWI index. The extracted shorelines were manipulated through the Digital Shoreline Analysis System (DSAS) software. The shoreline change rates were compared with sediments grain size for the past thirty years, heavy minerals content and radioactivity of recent marine sediment samples collected from different locations of marine profiles over the study area. The study revealed that Damietta Promontory has suffered from erosion during the study period reached its maximum shoreline retreat at the eastern side, nearly – 43 m/y. The total cumulative shoreline regression during the study period at this area was 1311m. The relation between the shoreline change process (erosion or accretion) and the physical parameters of coastal sediment showed that; as erosion increases, the heavy minerals content and radioactivity increases, while the mean grain size decreases and vice versa.
The Impact of Social Accountability Mechanisms on Fiscal Management Challenges Facing Goromonzi Rural District Council, Zimbabwe
Authors: Madhovi Trust
Published: May 2020

This paper examines the impact of social accountability mechanisms on the fiscal management challenges facing local government bodies in Zimbabwe. The paper hypothesises that there is a positive relationship between the use of social accountability mechanisms or tools by local authorities and the effectiveness of their fiscal management policies to mobilize more revenue for service delivery. In this study, both quantitative and qualitative methods are adopted in gathering and analysing data from central government officials, Goromonzi Rural District Council employees and members of the public. The results of the study reveal that the local government body faces a number of fiscal management challenges that include a shrinking tax base, non-payment of taxes, resistance to successive budgets; lack of implementation; lack of monitoring and evaluation. Council has implemented participatory budgeting to deal with some of these challenges. While results show a significant improvement in tax collection, some of the challenges have persisted. The paper proposes some recommendations useful to central government, policy makers, civil society organisations, local government officials and the general public. The paper manages to demonstrate that the implementation of social accountability tools can have positive impacts on the fiscal management challenges facing local governments.

The study offers the implication that to realize the benefits of oil and gas resources for the long-term development of Tanzania, policymakers should ensure institutional and enterprise development, and promotion of governance framework to enhance transparency and accountability in the oil and gas sector. Moreover, we recommend that the realization of long-term extraction and sustainable development of oil and gas resources in Tanzania, robust policies, strategies, good governance frameworks and combined efforts of the government, oil companies, and private sector, civil organizations, and citizens’ participation in the management of oil and gas resources is of critical importance.
Modos de pertencimento, fontes de guerra: nacionalismo e identidade religiosa nos séculos XX e XXI
Authors: Vargas Maia Tatiana
Published: May 2020

O propósito deste artigo é mapear os pontos de semelhança existentes entre identidades religiosas e identidades nacionais, identificando algumas vias de acesso que permitam articular uma reflexão a respeito da relação entre os efeitos da politização de identidades religiosas e nacionalistas e as nossas formas de conflito e guerra. Inicialmente, apresento os conceitos fundamentais de nacionalismo e religião, conforme estabelecidos na literatura da História e das Ciências Sociais. Na sequência, relaciono as noções de identidade nacional e identidade religiosa com a incidência de conflitos violentos, explorando como esses padrões de pertencimento político e social específicos podem servir como combustível para a incidência de violência política.
A indústria frigorífica no oeste catarinense e a participação dos ítalos (1940-1960)
Authors: Radin José Carlos
Published: May 2020

Analisa a participação dos ítalo-brasileiros no processo de desenvolvimento da indústria frigorífica do Oeste catarinense (1940-1960). Apresenta a região, enquanto fronteira agrícola ocupada por colonos e o perfil dos líderes na criação dos frigoríficos, bem como aponta razões da modernização dessa indústria. Evidencia os fatores da gênese de tal processo industrial, em particular os que favoreceram a acumulação de capital por algumas famílias e o reinvestimento na formação de sistemas produtivos que se especializaram no processamento de carne suína. Fundamenta-se principalmente na literatura existente sobre o tema, destacando que o surgimento e estruturação dos frigoríficos se deve sobretudo aos descendentes de italianos, cujas famílias, compuseram inicialmente os assentamentos agrícolas e, gradativamente, empreenderam no comércio e acumularam capital, o que lhes permitiu investir também na indústria frigorífica.
Guenoa minuanos: caciques y territorio
Authors: Bracco Diego , Lopez Mazz José María
Published: May 2020

Este artículo está centrado en el análisis del rol desempeñado por los caciques de la nación que los jesuitas denominaron guenoa y el resto de la sociedad colonial minuan. Parte relevante del trabajo está centrado en el sistema jerárquico -con la existencia de un jefe máximo- que tuvieron durante dilatado lapso. Asimismo en la superioridad que al parecer mantuvieron sobre sus propios dirigentes religiosos. También se analizan fuentes que permiten aproximarse a los requisitos o circunstancias necesarias para obtener el rango de cacique. Igualmente, las referidas a la poligamia que practicaron; así también las relacionadas con el ganado que tuvieron en régimen de propiedad privada. Por último, se formulan consideraciones sobre el dilatado espacio en el que ejercieron su dominio y sus relaciones con aquel donde está emplazada gran cantidad de los denominados “cerritos de indios”.
Conceitos, intelectuais e ideias: o entrelaçamento de diferentes dimensões do campo da história, no caso do debate entre Eugênio Gudin e Celso Furtado (1950-1964)
Authors: Ramos Rocha de Lima Neilaine
Published: May 2020

Por mais importante que o referencial teórico posso ser, dentro da pesquisa histórica, a análise do objeto precisa ser tratada como foco principal do ofício do historiador. O objeto nos direciona aos referenciais teóricos. Tendo como premissa isso, ao analisar um debate entre dois grandes intelectuais brasileiros, Celso Furtado e Eugênio Gudin, nas décadas de 1950 e 1960, fica clara a necessidade de recorrermos a diferentes dimensões do campo da história, principalmente quando se observam a construção de distintas concepções da dinâmica da história, encontradas em ambos ideários, o desenvolvimentismo de Furtado e o liberalismo de Gudin. Sendo assim, não há como entender esse debate sem recorrermos aos princípios da história dos conceitos, as ferramentas da história dos intelectuais, para assim compreendermos a dinâmica da história dessas ideias na vida política e na história intelectual do Brasil.
El agronegocio en la producción de granos, sus resultados económicos y su relación con las políticas públicas en un país dependiente
Authors: Pierri José
Published: May 2020

El modelo de agronegocios, dominante en la producción de granos en Argentina desde los años 90 fue difundido por distintas entidades representativas del sector, diversas publicaciones  y numerosos trabajos académicos. La mayoría de las opiniones destacaron  su conveniencia a la hora de bajar costos y  mejorar la  rentabilidad, pero no abundan trabajos que contrasten con estudios estadísticos la conveniencia económica de la adopción del modelo a través del tiempo y la influencia de las políticas públicas sobre la rentabilidad. Este trabajo busca estudiar, a través de la construcción de series estadísticas sobre costos de producción y gastos de comercialización de trigo y soja, la evolución de esos aspectos durante las tres grandes etapas de política económica que afectaron al sector entre 1990 y 2017 y analizar sus resultados económicos en las explotaciones. Con esos datos formula consideraciones que buscan profundizar el análisis de los supuestos centrales del agronegocio y de la influencia de las políticas públicas sobre el sector. Las reflexiones finales recuerdan el carácter estructuralmente dependiente de la economía argentina, aspecto del que debe partir el estudio de la evolución de la producción y exportaciones de cereales y oleaginosas en las últimas décadas.  Utiliza como base estadística publicaciones de la Bolsa de Cereales de Buenos Aires, por el Instituto de Estudios  de la Realidad Argentina y Latinoamericana  (IERAL) y, en particular, los Informes Anuales realizados por Filial Marcos Juárez del Instituto Nacional de Tecnología Agropecuaria.
Análisis comparativo de las relocalizaciones compulsivas rural y urbana: La represa de Itá (Alto Uruguay, Brasil) ( 1979-2001)
Authors: Catullo María Rosa
Published: May 2020

En este trabajo estudiamos los efectos de la construcción de la represa de Itá (Brasil) ubicada  en el río Uruguay, entre los municipios de Itá (Estado de Santa Catarina) y Aratiba (Estado de Río Grande del Sur), La misma formó un lago que tiene una cota de 370 metros (“m s. n. m.”), con un volumen total de 5.100 millones de metros cúbicos, ocupando 141 Km² de área total. Presenta un potencial instalado de 1620 MW y afectó en su gran mayoría áreas rurales, parcialmente el municipio de Marcelino Ramos (RS ) y en su totalidad la sede del municipio de Itá (SC). Analizamos comparativamente las estrategias y respuestas de la población rural  que se organizó en la Comissão  Regional de Atingidos  por Barragem (CRAB), resistiendo a la construcción de la represa, en contraposición a la población de la ciudad de Itá que estuvo “mayormente”, a favor de la misma.
O Posto Agropecuário de Ijuí e a modernização da agricultura
Authors: Gerhardt Marcos , Zarth Paulo Afonso
Published: May 2020

o artigo trata do papel do Posto Agropecuário de Ijuí, implantado pelo Ministério da Agricultura na década de 1940 para fomentar a modernização agrícola na região noroeste do Rio Grande do Sul, a qual se destacou na história da agricultura pelo desenvolvimento das lavouras de trigo e soja. O período de instalação dessa instituição de difusão de tecnologias precede a Revolução Verde no sul do Brasil e significou uma importante colaboração para o posterior desenvolvimento dessa. Interpretamos o conteúdo de documentos arquivados no Museu Antropológico Diretor Pestana, produzidos pelo diretor do Posto Agropecuário e artigos publicados no jornal Correio Serrano. A perspectiva da análise é da história agrária e da história ambiental, com ênfase no papel do Estado como agente de difusão de novas tecnologias e nos impactos socioambientais decorrentes do processo de modernização da agricultura no período de 1940 a 1976.
Siete Instantes (Diana Cardozo, 2008): a militância sob lentes intimistas
Authors: Martins Villaça Mariana
Published: May 2020

Nesse artigo analisamos o documentário uruguaio-mexicano Siete Instantes (Diana Cardozo, 2008), realizado a partir de entrevistas a ex-militantes políticos uruguaios, especialmente mulheres, que relatam suas experiências no contexto autoritário e ditatorial daquele país. Procuramos ressaltar seu caráter de documento histórico, focando o momento político de sua produção, no qual eclodem políticas de memórias. Levantamos ainda algumas questões sobre a especificidade do olhar feminino que constrói por meio dos elementos fílmicos e o diálogo que estabelece com alguns debates presentes na historiografia sobre o período.
