A destruição de habitats atrelada à fragmentação causa sérias consequências para qualquer tipo de vegetação, principalmente para a Mata Atlântica na Região Nordeste. Os Brejos de Altitudes Nordestinos são áreas que apresentam microclimas dissociantes das extensões onde estão inseridos. O conhecimento do potencial de regeneração natural é fundamental para a compreensão da dinâmica da vegetação. Este trabalho teve como objetivo avaliar a o recrutamento e a mortalidade de regenerantes de Anadenanthera colubrina ocorrente em fragmento florestal de Floresta Ombrófila Aberta. Em uma população de A. colubrina as parcelas foram demarcadas, onde existiam plantas matrizes, com plântulas regenerantes, sendo 10 parcelas fixas (10 m x 10 m), onde todos os exemplares dessa espécie menor ou igual a 1 m de altura foram marcados, numerados e acompanhados durante 9 meses. O diâmetro caulinar do táxon apresentou crescimento constante. O incremento médio mensal inicial em diâmetro foi de 1,8 mm e final de 2,3 mm e o incremento médio em altura foi de 20 cm no primeiro mês e 25,9 cm no último mês avaliado. A taxa de mortalidade chegou a 50%. Os fatores ambientais e antrópicos e a predação das sementes contribuem para a mortalidade dos regenerantes.Structure of natural regeneration in Anadenanthera colubrina altitude swamp fragment in Bananeiras, PB, BrazilThe habitats destruction linked to fragmentation causes serious consequences for vegetation in general, especially considering the Northeast Atlantic Forest. The Northeastern Swamps of Altitudes are areas with microclimates dissociating from extensions where they are inserted. Knowledge of the natural regeneration potential is the key to understanding the dynamics of vegetation. The study aimed to evaluate the recruitment and mortality of Anadenanthera colubrina regenerating occurring in Open Rain Forest fragments. In a population of A. colubrina, ten plots with 10 m x 10 m were established, near matrices plants. All specimens with 1 m height or lower were numbered and monitored for 9 months. The stem diameter of the taxon showed continuous growth. The monthly average increment in diameter was at first 1.8 mm and at the end 2.3 mm, and the average stem increment in height was 20 cm at the first month and 25.9 cm at the last month evaluate. The mortality rate reached 50%. Environmental and anthropogenic factors and seed predation contribute to mortality of regenerating individuals.Index terms: Abiotic factors; Recruitment; Mortality

<p>En los estudios superiores, al igual que en los demás contextos educativos, no basta con adquirir una serie de conocimientos, es indispensable reflexionar sobre los propios procesos cognitivos para tomar decisiones autónomas y fundamentadas respecto de los aprendizajes. Aprender va mucho más allá de las cuestiones cognitivas, las emociones puestas en juego y las posibilidades de reflexionar respecto de los aprendizajes resultan decisivas en los complejos procesos de construcción de conocimientos. El objetivo del estudio es analizar aspectos metacognitivos vinculados al aprendizaje académico de estudiantes de primer año del Profesorado en Educación Inicial de la Universidad Nacional de Río Cuarto y del Instituto Superior María Inmaculada (Argentina). En la primera parte de la investigación, los estudiantes respondieron a un cuestionario general referido a prácticas y hábitos de estudio y a un inventario de patrones de aprendizaje: ILS (Vermunt, 1998). Luego, se realizaron entrevistas grupales con los estudiantes con el propósito de conocer diferentes puntos de vista respecto de las prácticas de estudio, aprendizaje y enseñanza en la educación superior. Los resultados muestran que la mayoría de los participantes requieren de regulaciones externas para desarrollar los procesos de aprendizaje. Se observan ciertas dificultades en la autorregulación de los procesos de lectura, escritura y en el estudio en general. Se propone desarrollar estrategias innovadoras que promuevan en los estudiantes prácticas reflexivas y metacognitivas respecto de los aprendizajes en contextos académicos. </p>
Occupational Therapy Home Safety Intervention via Telehealth

Published: July 2016

Photography can be an effective addition for education-based telehealth services delivered by an occupational therapist. In this study, photography was used as antecedent to telehealth sessions delivered by an occupational therapist focused on narrative learning about home safety. After taking photographs of past home safety challenges, six participants experienced three web-based occupational therapy sessions each. Sessions were recorded and transcribed. Data were examined using content analysis. A content analysis identified the following themes as well as an understanding of the learning process. Analyses yielded themes of: the value of photos to support learning, the value of narrative learning related to home safety education, abstract versus concrete learners. Procedural findings are included to support future endeavors. Findings indicate that within a wellness context, home safety education for older adults can be delivered effectively via telehealth when using photography as a part of an occupational therapy intervention.

Onésimo: um personagem silencioso no Bilhete a Filêmon?
Authors: Ferreira Joel Antônio 
Published: July 2016

<p>Pelos Métodos bíblicos tradicionais (Histórico-Crítico e Crítico-Literário) já se estudou o Bilhete a Filêmon, aprofundando o protagonista Paulo dentro dos modos de produção escravagista romano. Com este artigo atual que usufrui o Método Sociológico pelo Modelo Conflitual/Contradição, a proposta é olhar o mesmo Bilhete a Filêmon, a partir de alguém que foi silenciado no texto original. Como este tipo de Leitura procura detectar as assimetrias, olhar o texto com «suspeição» e dar voz e espaço aos que estão na «margem», o protagonista passa a ser aquele que estava abaixo da pirâmide romana: Onésimo, o escravo. A hipótese deste artigo é que, na prisão, o escravo Onésimo passou do estado da passividade para se tornar um questionador da prática de Paulo. O Apóstolo, então, na crueza da cadeia, sentiu-se tocado. Sua <em>práxis</em>, agora, concretizou-se na luta pela liberdade do escravo. Onésimo teria transformado a conversão de Paulo. Com essa leitura, descobre-se Jesus Cristo na carne do escravo.</p>
Jednodetnosť: pre a proti
Authors: Popper Miroslav 
Published: July 2016

V príspevku sú analyzované vybrané dáta týkajúce sa protichodných názorov na optimálny počet detí v súčasnej rodine v kontexte existenčnej neistoty. Údaje boli získané v rámci širšieho kvalitatívneho výskumu zameraného na rodičovstvo a reprodukciu. Vzorka pozostáva z 18 fókusových skupín, ktoré sa uskutočnili v troch regiónoch Slovenska – západnom strednom a východnom. V každom regióne prebehlo šesť fókusových diskusií, z ktorých tri sa realizovali s ekonomicky lepšie a tri s ekonomicky horšie situovanými rodičmi. V rovnakom pomere sa skupiny delili aj podľa počtu detí (polovica jednodetných a polovica dvojdetných skupín). V jednotlivých fókusových skupinách bolo takmer vždy rovnomerné zastúpenie mužov a žien. Výsledky poukazujú na to, že rodičia s jedným dieťaťom sú rodičmi s dvoma deťmi pomerne schematicky kritizovaní kvôli mamonu, materializmu a karierizmu, ako aj sebeckosti a nezodpovednosti. Jednodetní rodičia však uvádzajú pestrejšiu škálu dôvodov, pre ktoré majú len jedno dieťa. Medzi nimi dominujú neistota na trhu práce, strach z prepustenia, nedostatok financií na splácanie hypoték a tiež snaha udržať si určitý životný štandard. Vo všeobecnosti jednodetní rodičia nemajú pocit, že sú sebeckí, ale naopak, považujú svoje rozhodnutie za zodpovedné vzhľadom na súčasnú situáciu charakterizovanú vysokou mierou nezamestnanosti.

Published: July 2016

Context.—Small glandular proliferations of the breast encompass a variety of benign, atypical, and malignant lesions that show some overlapping morphologic features. Myoepithelial stains are frequently used in the workup of these lesions in order to rule out or establish a diagnosis of invasive carcinoma. Some benign lesions show absent or diminished myoepithelial staining, and may represent an interpretative pitfall, particularly in small core biopsy samples.Objective.—To review small glandular proliferations of the breast that show absent or diminished staining with myoepithelial immunohistochemical markers.Data Sources.—The study comprised a review of published literature and clinical case material.Conclusions.—The interpretation of myoepithelial stains in small glandular proliferations of the breast can, on some occasions, represent a challenge in diagnosing these lesions. Recognition of the key histopathologic features and immunohistochemical staining patterns of the entities in the differential diagnosis is crucial in their workup.

A baixa qualidade de mudas pode advir de problemas na irrigação e/ou nutrição das mudas em sua fase de formação em viveiros. Em relação à irrigação, problemas podem surgir referentes à má distribuição da água ou mesmo seu manejo, levando ao deficit ou ao excesso de irrigação, enquanto o excesso pode lixiviar nutrientes, o deficit pode prejudicar o desenvolvimento da planta. Assim, o presente trabalho teve como objetivos avaliar a eficiência de irrigação de um sistema de irrigação por microaspersão já instalado em um viveiro de mudas de espécies florestais e também avaliar a eficiência de um sistema de subirrigação de mudas florestais nativas cultivadas em tubetes. A avaliação da eficiência da microaspersão foi realizada em um viveiro de mudas de espécies nativas florestais na cidade de Itutinga - MG, o delineamento utilizado foi o inteiramente casualizado (DIC) em esquema de parcelas subdivididas, estando o equipamento de irrigação na parcela (três níveis: MA-20, Rondo e Inverted Rotor Spray) e três espécies florestais na subparcela. Na avaliação de eficiência em tubetes de 300 cm³, as categorias da subparcela foram: araucária (Araucaria angustifolia (Bert.) O. Ktze.), jerivá (Syagrus romanzoffiana (Cham.) Glassman) e cutieira (Joannesia princeps Vell.). Em tubetes de 110 cm³ os três níveis da subparcela foram as espécies: mutamba (Guazuma ulmifolia Lam.), angico-vermelho (Anadenanthera macrocarpa Benth.) e peroba-rosa (Aspidosperma polyneuron Muell.). A avaliação da eficiência da subirrigação foi realizada em uma estufa localizada na Universidade Federal de Lavras, em dois tanques de subirrigação em três repetições. As maiores eficiências de aplicação foram obtidas para o emissor modelo MA-20. Não houve diferenças significativas entre a eficiência de aplicação dos microaspersores em relação às espécies estudadas, em ambos os tubetes. A eficiência de irrigação no tanque de tubetes de 300 cm³ foi 90,42%, enquanto para tubetes de 110 cm³ foi 92,17%. Os tanques de subirrigação mostraram-se como alternativa interessante para irrigação de mudas das espécies florestais testadas, apresentando alta eficiência para os dois tamanhos de tubetes avaliados.

Linking microearthquakes to fracture permeability change: The role of surface roughness

Published: July 2016

AbstractDespite its importance, the relation between microearthquakes (MEQs) and changes in hydraulic properties during hydraulic stimulation of a fractured reservoir has rarely been explored, and it is still not well understood. To investigate this relation, we first formulate a plausible scale dependence, where fracture length and shear displacement are variables, for channeling flow through heterogeneous aperture distributions for joints and faults. By combining this formulation with the concept of the seismic moment, we derive quantitative relations between the moment magnitude (Mw) of MEQs and the fracture permeability change in the directions orthogonal to (kfault,⊥/kjoint) and parallel to (kfault,∥/kjoint) the shear displacement, in the form
and
. Despite the simplicity of the derivation, these relations have the potential to explain the results of field experiments on hydraulic stimulation, such as the enhanced geothermal systems at Soultz‐sous‐Fôret and Basel.
The effects of Antarctic iceberg calving‐size distribution in a global climate model
Authors: Stern A. A. , Adcroft A. , Sergienko O. 
Published: July 2016

AbstractIcebergs calved from the Antarctic continent act as moving sources of freshwater while drifting in the Southern Ocean. The lifespan of these icebergs strongly depends on their original size during calving. In order to investigate the effects (if any) of the calving size of icebergs on the Southern Ocean, we use a coupled general circulation model with an iceberg component. Iceberg calving length is varied from 62 m up to 2.3 km, which is the typical range used in climate models. Results show that increasing the size of calving icebergs leads to an increase in the westward iceberg freshwater transport around Antarctica. In simulations using larger icebergs, the reduced availability of meltwater in the Amundsen and Bellingshausen Seas suppresses the sea‐ice growth in the region. In contrast, the increased iceberg freshwater transport leads to increased sea‐ice growth around much of the East Antarctic coastline. These results suggest that the absence of large tabular icebergs with horizontal extent of tens of kilometers in climate models may introduces systematic biases in sea‐ice formation, ocean temperatures, and salinities around Antarctica.
Stability of grassland soil C and N pools despite 25 years of an extreme climatic and disturbance regime
Authors: Wilcox Kevin R. , Blair John M. , Knapp Alan K. 
Published: July 2016

AbstractGlobal changes are altering many important drivers of ecosystem functioning, with precipitation amount and disturbance frequency being especially important. Carbon (C) and nitrogen (N) pools are key contemporary attributes of ecosystems that can also influence future C uptake via plant growth. Thus, understanding the impacts of altered precipitation amounts (through controls of primary production inputs) and disturbance regimes (through losses of C and N in biomass) is important to project how ecosystem services will respond to future global changes. A major difficulty inherent within this task is that drivers of ecosystem function and processes often interact, resulting in novel ecosystem responses. To examine how changes in precipitation affect grassland ecosystem responses under a frequent disturbance regime (annual fire), we assessed the biogeochemical and ecological consequences of more than two decades of irrigation in an annually burned mesic grassland in the central United States. In this experiment, precipitation amount was increased by 31% relative to ambient and 1 in 3 years were statistically extreme relative to the long‐term historical record. Despite evidence that irrigation decreased root:shoot ratios and increased rates of N cycling—each expected to reduce soil C and N with annual burning—we detected no changes in these biogeochemical pools. This surprising biogeochemical resistance highlights the need to explore additional mechanisms within long‐term experiments concerning the consequences of global change impacts on ecosystems.
Coupling spectral‐bin cloud microphysics with the MOSAIC aerosol model in WRF‐Chem: Methodology and results for marine stratocumulus clouds
Authors: Gao Wenhua , Fan Jiwen , Easter R. C. , Yang Qing , Zhao Chun , Ghan Steven J. 
Published: July 2016

AbstractAerosol‐cloud interaction processes can be represented more physically with bin cloud microphysics relative to bulk microphysical parameterizations. However, due to computational power limitations in the past, bin cloud microphysics was often run with very simple aerosol treatments. The purpose of this study is to represent better aerosol‐cloud interaction processes in the Chemistry version of Weather Research and Forecast model (WRF‐Chem) at convection‐permitting scales by coupling spectral‐bin cloud microphysics (SBM) with the MOSAIC sectional aerosol model. A flexible interface is built that exchanges cloud and aerosol information between them. The interface contains a new bin aerosol activation approach, which replaces the treatments in the original SBM. It also includes the modified aerosol resuspension and in‐cloud wet removal processes with the droplet loss tendencies and precipitation fluxes from SBM. The newly coupled system is evaluated for two marine stratocumulus cases over the Southeast Pacific Ocean with either a simplified aerosol setup or full‐chemistry. We compare the aerosol activation process in the newly coupled SBM‐MOSAIC against the SBM simulation without chemistry using a simplified aerosol setup, and the results show consistent activation rates. A longer time simulation reinforces that aerosol resuspension through cloud drop evaporation plays an important role in replenishing aerosols and impacts cloud and precipitation in marine stratocumulus clouds. Evaluation of the coupled SBM‐MOSAIC with full‐chemistry using aircraft measurements suggests that the new model works realistically for the marine stratocumulus clouds, and improves the simulation of cloud microphysical properties compared to a simulation using MOSAIC coupled with the Morrison two‐moment microphysics.
A linear programming approach to online set membership parameter estimation for linear regression models
Authors: Casini M. , Garulli A. , Vicino A. 
Published: July 2016

SummaryThis paper presents a new technique for online set membership parameter estimation of linear regression models affected by unknown‐but‐bounded noise. An orthotopic approximation of the set of feasible parameters is updated at each time step. The proposed technique relies on the solution of a suitable linear program, whenever a new measurement leads to a reduction of the approximating orthotope. The key idea for preventing the size of the linear programs from steadily increasing is to propagate only the binding constraints of these optimization problems. Numerical studies show that the new approach outperforms existing recursive set approximation techniques, while keeping the required computational burden within the same order of magnitude.
