Escritos e invenções da experiência do grupo teatral CERA : outros ditos, outros espaços-tempos
Authors: Ziliani Rosemeire de Lourdes Monteiro 
Published: July 2017

Escritos e invenciones de la experiencia del grupo teatral del CERA: otros dichos, otros espacios-tiempos El artículo socializa parte de una investigación ya concluida sobre las obras teatrales escritas y ensayadas por el Grupo Teatral del CERA, que estuvo en actividad por veinte años en una escuela técnica, llamada Centro de Educación Rural de Aquidauana (CERA), ubicada en la municipalidad de Aquidauana, Mato Grosso do Sul. El estudio sobre el teatro ha utilizado textos de algunas obras, folletos, periódicos y testimonios. En el análisis y problematización del material seleccionado se ha dialogado con estudios foucaultianos. Desde esta perspectiva, los materiales han sido desjerarquizados, considerados constituidores de la realidad y de los sujetos e involucrados en lo que se puede llamar “dispositivo de escolarización”. Se ha considerado la producción teatral como uno entre otros discursos que se entrecruzaron en los programas de aquella Institución escolar para la constitución de sujetos capacitados para actuar como técnicos. Sin embargo, y diferentemente de las demás prácticas discursivas reproducidas/producidas en la escuela, a la actividad teatral se le ha atribuido la tarea de formar público para el teatro y (re)inventarle una identidad al sur-matogrossense, tras la división del Estado de Mato Grosso, a fines de los años 70. Funcionando como Grupo Teatral en el período del 1978 al 1997, fueron producidas y escenificadas diecinueve obras, una cada año. El autor arrojó luz sobre una diversidad de hechos históricos y socioculturales, tomándolos como material fundador de la identidad por ser construida. Rodeados por el estudio, por el trabajo y por el aislamiento del colegio internado, el ejercicio colectivo de la experiencia teatral intentó contribuir para la configuración de la identidad y puede haber afectado a los jóvenes en sus “vidas comunes”.
Marguerite in Champagne
Authors: Piron Sylvain 
Published: July 2017

Abstract
The life of Marguerite, called Porete, is remarkably obscure. All we know about her derives either from her book, the Mirror of Simple Souls, or from documents connected to her condemnation in Paris in 1310. For this reason, scholars are constrained to make guesses and suppositions about her actions. This article aims in the first place at exerting a tighter control on the use of imagination in reconstructing Marguerite's life. By making sense of some hitherto neglected details, it establishes a crucial fact. An intermediary stage must be posited between her initial condemnation in Valenciennes (before 1305) and her final trial in Paris. She certainly passed through Châlons-en-Champagne in 1308. This is where she was seized by the local bishop, before being sent to Paris.
The Spaces of Citizenship: Mapping Personal and Colonial Histories in Contemporary Italy in Igiaba Scego’s La Mia Casa È Dove Sono (My Home is Where I Am)
Authors: Paynter Eleanor 
Published: July 2017

As Italy has changed from emigration country to immigration destination, the growing body of literature by migrant and second generation writers plays an important role in connecting discourses on race and national identity with the country’s increasing diversity and its colonial past. This essay investigates the 2010 memoir La Mia Casa È Dove Sono (My Home is Where I Am) by Igiaba Scego, the daughter of Somali immigrants, as life writing that responds to these changing demographics and, more broadly, to the migration trends affecting contemporary Europe. The self Scego constructs through her narration integrates her Roman identity and Somali background as the narrative returns colonial history to Italian public discourse and public space. I argue that by narrating the personal and historical in the context of Roman monuments and neighborhoods, Scego’s memoir challenges and redefines who can be “Italian,” modeling a more inclusive Italianità. I discuss the memoir in terms of its use of collective memory and its development of a narrative “I” that claims a position within a collective identity while challenging the exclusionary tendencies of that very group. This article was submitted to the European Journal of Life Writing on June 8th, 2016, and published on July 17th, 2017.
The integrated curriculum, university teacher identity and teaching culture: the effects of an interdisciplinary activity
Authors: Alonso Sáez Israel , Berasategi Sancho Naiara 
Published: July 2017

Abstract
The results of an investigative process are reported that centre on the impact that modular curricular organization and its interdisciplinary activity are having on the teaching culture in the Degree in Social Education at the University of the Basque Country (UPV/EHU). This understanding of the curriculum is a seminal change for teaching staff and affects their professional identity by encouraging co-responsibility throughout the process. Communicative methodology is employed, which assists in the integration of the people in the investigation, so that they form part of the process of study under equal terms. The production of data was done through in-depth interviews, discussion groups, and documental analysis. The Interdisciplinary Activity Module (IAM) was developed in small groups, of 12–15 individuals, through active methodologies, and the university teachers needed to incorporate it into their discourse and relations with other colleagues and with their students. The results show that an integrated curriculum provides a worthwhile training opportunity to achieve learning of greater significance and depth, and that it happens through changes in their ways of relating and acting as teachers.
Internet and people with intellectual disability: an approach to caregivers’ concerns, prevention strategies and training needs
Authors: Chiner Esther , Gómez-Puerta Marcos , Cardona-Moltó M. Cristina 
Published: July 2017

Abstract
The aim of this study was to explore caregivers’ views about the risks of the Internet for people with intellectual disabilities and their preparation and ability to use prevention strategies to address them. The participants (20 family members and 24 staff members) belonged to a non-profit association working with people with developmental and intellectual disabilities and were asked to respond to a questionnaire about Internet safety and risks. Findings show some concerns from caregivers with regard to the use of the Internet by people with intellectual disabilities and suggest that this group is more vulnerable to online risks. Participants use different kinds of strategies to prevent the risks but they have not received any formal training. They think that this training should come from the Administration and other organisations. Some differences were found between family and staff members’ responses. Training programmes for all the groups involved in this process (i.e. people with intellectual disabilities, staff and family members) should be designed, implemented and assessed to promote the inclusion of people with intellectual disabilities in the digital arena.
Diagnosis of the Skills of the Master’s Degree: Case Study at the University Pablo of Olavide
Authors: Ordóñez Olmedo Eva , Ramírez-Fernández Miguel Baldomero 
Published: July 2017

Abstract
The work team of the Postgraduate Studies Centre (henceforth CEDEP) of Pablo de Olavide University (henceforth UPO) has submitted a questionnaire in order to identify the training needs of the directors of the master’s degrees which are implemented in The UPO during the academic year 2016/2017. This article aims to analyze how the lessons are planned and how the acquisition of the competencies defined in each master’s degree are achieved, in order to assess the current situation and propose solutions for university quality improvement. This research presents a mixed design: quantitative and qualitative non-experimental descriptive through a questionnaire. Further to the study analysis conducted, the need to create a manual of recommended practice to arrange curricula by competencies at the master level is presented, as 62.16% of the participants reflect a great lack of knowledge about the theoretical description of the competencies classification and 73% support a complementary material need for the design of the curriculum.

AbstractHigh‐resolution multiproxy records, including clay minerals and Sr‐Nd‐Pb isotopes of the clay‐sized silicate fraction of sediments from IODP Site U1429 in the northern Okinawa Trough, provide reliable evidence for distinct control mechanism on fine‐grained sediments input from the Yellow River and the southern Japanese Islands to the northern Okinawa Trough since 34 ka BP. Provenance analysis indicates that the sediments were mainly derived from the Yellow River and the island of Kyushu. Since the last glacial, clay‐sized sediments transported from the Yellow River to the study site were strongly influenced by sea‐level fluctuation. During low sea‐level stage (∼34–14 ka BP), the paleo‐Yellow River mouth was positioned closer to the northern Okinawa Trough, favoring large fluvial discharge or even direct input of detrital sediments, which resulted about four times more flux of clay‐sized sediments supply to the study area as during the relatively high sea‐level stage (∼14–0 ka BP). The input of Kyushu‐derived clay‐sized sediments to the study site was mainly controlled by the Kuroshio Current and Tsushima Warm Current intensity, with increased input in phase with weakened Kuroshio Current/Tsushima Warm Current. Our study suggests that the Kuroshio Current was very likely flowed into the Okinawa Trough and thus influenced the fine‐grained sediment transport in the area throughout the last glacial and deglacial. During ∼34–11 ka BP, the Kyushu clay‐sized sediment input was mainly controlled by the Kuroshio Current. Since ∼11 ka BP, the occurrence of Tsushima Warm Current became important in influencing the Kyushu fine‐grained sediment input to the northern Okinawa Trough.
An efficient radiative transfer model for hyperspectral IR radiance simulation and applications under cloudy‐sky conditions

Published: July 2017

AbstractAn efficient radiative transfer model has been developed for hyperspectral infrared radiance simulation under both clear‐ and cloudy‐sky conditions. The hyperspectral IR cloudy radiative transfer model (HIRTM) combines atmospheric transmittances due to molecular absorption and cloud absorption and scattering from cloud hydrometeors. An efficient analytical Jacobian methodology is also developed under both clear‐ and cloudy‐sky conditions, which is needed both to assimilate cloudy radiances directly into numerical weather prediction models and to retrieve atmospheric soundings and cloud properties simultaneously from cloudy radiance measurements. In comparing HIRTM and its analytical Jacobian with the community radiative transfer model (CRTM), our research has shown that HIRTM's Jacobian calculations are similar to those of CRTM. HIRTM and CRTM synthetic observations derived from model output are compared with corresponding real observations from Geostationary Operational Environmental Satellite 13 Imager observations, and both perform similarly under water clouds, while CRTM is colder than HIRTM for thick ice clouds.
Fore‐arc seafloor unconformities and geology: Insight from 3‐D seismic geomorphology analysis, Peru

Published: July 2017

AbstractNew 3‐D seismic data collected over 4870 km2 in the 3°45′S–12°30′S Peruvian segment of the East Pacific subduction system image seafloor erosional surfaces that can be mapped across the fore‐arc basins. Fore‐arc basins experience various stresses, from their base where basal tectonic erosion acts to the seafloor which is influenced by aerial, shallow, and deep water currents driven by waves or thermohaline oceanic currents. Previously there has been little interest in stresses on the upper layer and there is a lack of documentation of unconformities and the erosive processes in certain bathymetric domains in fore‐arc basins. We address this with the study of examples sourced from 3‐D seismic reflection surveys of the seafloor offshore Peru. Unconformities occur in two distinctive bathymetric domains associated with the continental shelf and the upper slope of the margin. Identification and characterization of unconformity surfaces yield estimates of the amount of erosion at the modern seafloor that range from 18 to 100%. Regional physical oceanography allows us to calibrate potential candidates for these two distinctive domains. The first control on erosion is the dynamics of deep to intermediate oceanic currents related to the Humboldt‐Peru Chile water masses, while the second is wave action in the shallower erosional surfaces. This study illustrates the unseen landscape of the fore‐arc basins of South America and helps to highlight the importance of erosive surficial processes in subduction landscapes.
Watershed geomorphology interacts with precipitation to influence the magnitude and source of CO2 emissions from Alaskan streams

Published: July 2017

AbstractBoreal ecosystems contain a large fraction of the world's soil carbon and are warming rapidly, prompting efforts to understand the role of freshwaters in carbon export from these regions. We examined geomorphic controls on the magnitude of stream CO2 emissions and sources of stream dissolved inorganic carbon (DIC) across a heterogeneous river basin in SW Alaska. We found that watershed slope and precipitation interact to control gaseous carbon fluxes from streams, with the highest flux from low‐gradient watersheds following rainstorms. Watershed slope influences C loading and stream CO2 fluxes by controlling carbon accumulation in watersheds and to a lesser extent by determining gas transfer velocity across the stream air‐water interface. Low gas transfer velocity in flat streams offsets some of the effects of higher terrestrial C loading at those sites, resulting in lower than expected vertical CO2 fluxes. While the isotopic composition of stream DIC (Δ14C and δ13C) was highly variable across space and time, shifts toward contemporary, terrestrial sources after precipitation were most pronounced in flat watersheds. At base flow DIC was a mixture of modern and aged sources of biogenic and geologic origin (Δ14C, −198.3‰ to 27.9‰, n = 23). Aged (Δ14C‐depleted) C sources contributed to food webs via a pathway from DIC to algae to invertebrate grazers. We observed coherent changes in stream carbon chemistry after large rainstorms despite considerable physical heterogeneity among watersheds. These patterns provide a way to extrapolate across boreal landscapes by constraining CO2 concentration and flux estimates by local geomorphic features.
Nonstationarity in threshold response of stormflow in southern Appalachian headwater catchments
Authors: Scaife Charles I. , Band Lawrence E. 
Published: July 2017

AbstractThreshold behavior of stormflow response is an emergent pattern observed in several studies demonstrating subsurface storage controls on catchment rainfall‐runoff dynamics. These studies demonstrate a distinct transition from negligible stormflow discharge response to rapid, linearly increasing stormflow identified by a single, uniquely defined threshold as a basic catchment attribute that relates to geophysical properties. Utilizing precipitation, streamflow, and soil moisture data spanning 15 years from three catchments at the Coweeta Hydrologic Laboratory (CHL), we analyze how threshold behavior forms and varies at several timescales. We pose three hypotheses: (1) stormflow thresholds form at CHL as a function of antecedent soil moisture and gross precipitation, (2) thresholds vary seasonally and interannually, and (3) threshold variation through time implies greater long‐term complexity of runoff controls beyond catchment geophysical properties, including forest canopy ecohydrologic feedbacks. We isolate threshold behavior of stormflow using piecewise regression analysis in short to long‐term data sets with respect to antecedent soil moisture index and gross precipitation. We use this to investigate threshold variation over seasonal, interannual, and decadal timescales that encompass hydroclimatic extremes. Seasonal analysis reveals that thresholds are more variable between growing seasons than between dormant seasons. In growing seasons with greater water stress, stormflow thresholds are lower after controlling for soil moisture storage suggesting more complex, long‐term rainfall‐runoff relationships as a result of forest canopy response to water stress. We present a conceptual model of how vegetation‐climate interactions influence long‐term rainfall‐runoff relationships creating interannual variability of stormflow thresholds and linear stormflow response.
TBAI/K2S2O8 Initiated Radical Cyclization to Synthesize β‐ Arylsulfonyl Naphthalenes from Homopropargylic Alcohols and Sulfonyl Hydrazides

AbstractA metal‐free radical addition method for the synthesis of β‐arylsulfonyl naphthalenes with homopropargylic alcohols and sulfonyl hydrazides has been developed. In this reaction, sulfonyl hydrazide is employed as the source of sulfonyl radical to produce the desired sulfone directly. There is the first example for homopropargylic alcohol through direct intramolecular addition of vinyl radical to arenes with sulfonyl radical, which is initiated by the TBAI/K2S2O8 reaction system and generates the desired products in moderate yields.magnified image

AbstractEfficient, stable catalysts with high selectivity for a single product are essential if electroreduction of CO2 is to become a viable route to the synthesis of industrial feedstocks and fuels. A plasma oxidation pre‐treatment of silver foil enhances the number of low‐coordinated catalytically active sites, which dramatically lowers the overpotential and increases the activity of CO2 electroreduction to CO. At −0.6 V versus RHE more than 90 % Faradaic efficiency towards CO was achieved on a pre‐oxidized silver foil. While transmission electron microscopy (TEM) and operando X‐ray absorption spectroscopy showed that oxygen species can survive in the bulk of the catalyst during the reaction, quasi in situ X‐ray photoelectron spectroscopy showed that the surface is metallic under reaction conditions. DFT calculations reveal that the defect‐rich surface of the plasma‐oxidized silver foils in the presence of local electric fields drastically decrease the overpotential of CO2 electroreduction.

Published: July 2017

AbstractTuning the selectivity of metal catalysts is of paramount importance yet a great challenge. A new strategy to effectively control the selectivity of metal catalysts, by tuning the lattice strain, is reported. A certain amount of Co atoms is introduced into Ru catalysts to compress the Ru lattice, as confirmed by aberration‐corrected high‐resolution transmission electron microscopy (HRTEM) and X‐ray absorption fine structure (XAFS) measurements. We discover that the lattice strain of Ru catalysts can greatly affect their selectivity, and Ru with 3 % lattice compression exhibits extremely high catalytic selectivity for hydrogenation of 4‐nitrostyrene to 4‐aminostyrene compared to pristine Ru (99 % vs. 66 %). Theoretical studies confirm that the optimized lateral compressive strain facilitates hydrogenation of the nitro group but impedes the hydrogenation of the vinyl group. This study provides a new guideline for designing metal catalysts with high selectivity.

Published: July 2017

ABSTRACTVascular endothelial growth factor‐A (VEGF) influences several physiological processes including endothelial cell function, angiogenesis and maintenance of organ/tissue capillarity. While the functional aspects of VEGF were vigorously investigated, only little detail is known on structural integrity of skeletal muscle fibers and capillaries in mice lacking VEGF expression in their muscles. Therefore, we assessed systematically the architecture of the glycolytic plantaris and the oxidative soleus muscles obtained from muscle‐specific VEGF knockout (mVEGF‐KO, n = 7) mice and their wild‐type (WT, n = 7) littermates by morphometry after transmission electron microscopy. The capillary/fiber ratio was lower (plantaris: −63.5%; soleus: −54.8%; P ≤ 0.05) in mVEGF‐KO mice than in WT mice. In plantaris, quantification of volume density (Vv) of compartments revealed higher Vv of total mitochondria (+56.5%, P ≤ 0.05) as well as higher Vv‐values for both intrafibrillar (+39%; P ≤ 0.05) and subsarcolemmal (+220%; P ≤ 0.05) mitochondrial pools in mVEGF‐KO mice than WT mice. The capillary phenotype also differed (P ≤ 0.05) between the two mouse‐strains: Vv (–17.4%), absolute area size (–19.1%) and thickness (–19.6%) of the endothelium layer were lower and Vv of capillary lumen (+15.1%) was higher in mVEGF‐KO mice than in WT littermates. In soleus, mitochondrial Vv in fibers and the structural indicators specific to the capillary phenotype exhibited the same tendency in differences between the mouse strains without reaching statistical significance. Our morphometric analysis demonstrates that the lower capillary supply in plantaris of mVEGF‐KO mice is accompanied by higher mitochondrial Vv in muscle fibers as well as lumen dilation and endothelium thinning of capillaries. These structural alterations were more pronounced in a glycolytic than an oxidative muscle. Anat Rec, 300:2239–2249, 2017. © 2017 Wiley Periodicals, Inc.
