Formação de Adultos Pouco Escolarizados: paradoxos da perspectiva da Aprendizagem ao Longo da Vida
Authors: Cavaco Carmen 
Published: March 2014

Neste artigo, procura-se analisar criticamente a perspectiva política da Aprendizagem ao Longo da Vida, tendo como referência as políticas e práticas orientadas para os adultos pouco escolarizados, em Portugal. Considera-se que, contrariamente ao discurso político da Agenda Europeia e das orientações políticas nacionais, a perspectiva da Aprendizagem ao Longo da Vida não visa uma educação para todos, nem todo o tipo de educação. A análise que se apresenta resultou de uma investigação de natureza qualitativa, que se baseou na recolha documental e estatística. Estes dados foram complementados com informação recolhida através de entrevistas, num território do sul de Portugal, composto por cinco municípios. Os dados empíricos recolhidos evidenciam que as orientações políticas referentes à perspectiva da Aprendizagem ao Longo da Vida dão lugar a práticas muito circunscritas de formação, que não atendem à riqueza e diversidade dos processos educativos e que, por esse motivo, não envolvem a globalidade dos cidadãos. A maior parte da formação realizada no território em estudo é orientada para adultos activos e baseia-se na forma escolar, o que dificulta a participação dos adultos pouco escolarizados.

Authors: Tavares Santos Jean Mac Cole , Pereira Milene Rejane , Rodrigues Érica Renata Clemente 
Published: March 2014

Neste trabalho apresenta-se alguns resultados de pesquisa realizada com graduandos do curso de licenciatura em Pedagogia da Universidade do Estado do Rio Grande do Norte (UERN) sobre o fenômeno da violência na escola. Tomou-se como referencial teórico para definição e problematização do conceito de violência os estudos de Andrade, Aquino, Abramovay e Rua, Araújo, Charlot, Bauman e Freire. Discute-se, assim, os vários conceitos de violência na escola. Para apreender as concepções discentes sobre o assunto, foram entrevistados vinte e oito graduandos do curso de Pedagogia buscando relacionar a compreensão deles sobre o fenômeno com os estudos sobre o tema. Pensou-se, com eles, que o docente deve partilhar saberes para gerir conflitos de violência na escola, através do diálogo, da ética profissional, da relação social de ensino-aprendizagem.
Currículo, cultura e crueldade: para compor uma ética com Antonin Artaud e o teatro
Authors: Oliveira Thiago Ranniery Moreira de , Paraíso Marlucy Alves 
Published: March 2014

Este artigo busca nas linhas de força de Antonin Artaud, do Teatro da Crueldade e da Filosofia da Diferença de Gilles Deleuze elementos para compor uma ética da crueldade curricular. Desenvolve-se, assim, o argumento de que a crueldade das formas de vida e a crueldade das forças de uma vida permitem alimentar exigência de uma ética da crueldade curricular. Expõe-se, desse modo, a dimensão ética e cultural da crueldade a partir do duplo formas/forças posto em jogo no Teatro da Crueldade. Extrai-se, portanto, uma ética da crueldade curricular que funciona a partir de dois movimentos: dar conta dos autoengendramentos das formas de vida em um currículo e pensar os movimentos fecundos que possibilitam a permanente invenção de formas de viver.
Formação inicial e a manifestação dos acadêmicos sobre a relação teoria e prática
Authors: Tozetto Susana Soares , Gomes Thais de Sá 
Published: March 2014

A teoria é entendida na percepção de Otaviano Pereira como a interiorização da prática, contemplação da ação prática. Pautado no conceito do referido autor, buscou-se investigar qual o conceito de teoria na percepção das acadêmicas do curso de Pedagogia, a fim de identificar nos depoimentos das mesmas, indícios que retratem qual a relação teoria/prática entendida. Assim, procura-se identificar nosdepoimentos das acadêmicas qual é o entendimento de teoria que elas apresentam e se o mesmo indica a compreensão da unidade da relação teoria e prática, aspecto que possibilitará a práxis. O que se identificou com a investigação foi que em determinado momento do curso as acadêmicas compreendem a teoria separada da prática. Comoresultado da investigação percebeu-se que somente um pequeno grupo de acadêmicas demonstraram compreensão do referido conceito, pois retratam em seus discursos o movimento dialético na fundamentação teórico/prática.
“Aprender para quê?” Uma análise da aprendizagem na educação escolar atual
Authors: Simão Pereira Clarice , Da Cunha Urt Sônia 
Published: March 2014

O propósito deste artigo é analisar a função da aprendizagem na educação escolar. Apresenta-se o recorte de uma entrevista de Ruben Alves, intitulada “Aprender para quê?”, e discute-se alguns aspectos principais da exposição do autor. O texto expõe que a educação escolar vem sendo menosprezada, com acentuado esvaziamento de conteúdo e redução do papel do professor a mero facilitador do processo de ensino e aprendizagem. A partir das questões levantadas, buscou-se fazer o contraponto, e conduzindo a análise por meio de interlocuções com outros autores, que defendem a educação escolar como lócus fundamental na formação humana, responsável pela socialização do conhecimento científico, artístico e filosófico, acumulado historicamente. Nesta direção, compreende-se que a aprendizagem está estritamente vinculada ao desenvolvimento humano, e pode se constituir em instrumento de luta e transformação.
Effects of Coencapsulation of Hepatocytes with Adipose-Derived Stem Cells in the Treatment of Rats with Acute-on-Chronic Liver Failure
Authors: Zhang Yue , Chen Xue-Min , Sun Dong-Lin 
Published: March 2014

Introduction Cell transplantation is an alternative to liver transplantation, which is hampered by short survival time and immunorejection. The goal of this study was to evaluate the therapeutic potential of hepatocytes coencapsulated with adipose-derived stem cells (ADSCs) in treating acute-on-chronic liver failure (ACLF). Methods Rat hepatocytes and ADSCs were isolated, and coencapsulated by alginate-poly-L-lysinealginate microencapsulation. The morphological and functional changes of heterotypic interactions were characterized. ACLF in rats was induced by D-galactosamine administration following CCl4-induced cirrhosis. These rats were subjected to intraperitoneal transplantation of 5 × 107 coencapsulated hepatocytes with ADSCs, 5 × 107 encapsulated hepatocytes alone, or empty vehicles after 24 h, respectively. The survival rate and liver functions were assessed. Results Hepatocyte performance levels such as albumin secretion and urea synthesis induction were all significantly enhanced in the coencapsulation group compared with the homo-encapsulated hepatocytes group (p<0.05). The results of cell cycle analysis showed that larger populations of hepatocytes with ADSC treatment were accumulated in the G2-S phase, and there were fewer in the G0-G1 phase compared to encapsulation of hepatocytes alone. Intraperitoneal transplantation of coencapsulated hepatocytes with ADSCs not only increased the survival rate, but also improved liver functions in a rat model of ACLF. Conclusions Transplantation of coencapsulated hepatocytes and ADSCs might be a promising strategy for cell-based therapy of acute liver diseases.

Published: March 2014

Background RIPK4 is essential for the identification of keratinocyte differentiation and cutaneous inflammation. The mechanisms involved in the tumorigenesis of tongue squamous cell carcinoma (TSCC) have not been well characterized yet. Objective To assess RIPK4 expression in various differentiated TSCC and to determine its basic biological function. Methods Overall, 109 human samples (36 normal tongue tissues and 73 surgically excised TSCC tissues with different degrees of differentiation) were collected for the present study. The expression of RIPK4 was assessed by real time PCR and immunocytochemistry. Multivariate logistic regression analysis was used to investigate the association between RIPK4 and clinical characteristics. In vitro analyses by scratch wound healing assay and invasion assays, as well as confocal laser scanning microscopy and flow cytometry analysis were performed using the Tca-8113 tongue cancer cell line. Cisplatin sensitivity analysis and cisplatin-induced activation of caspase 8 analysis were also performed. Results A significantly higher level of RIPK4 was found in well-differentiated TSCC samples than in the poorly differentiated ones (p<0.01). Male patients had relatively higher levels of RIPK4 (p=0.03). RIPK4 levels were also increased in older patients. In vitro, RIPK4 reduced the migration and invasion of the Tca-8113 cell line, but did not affect apoptosis and cell cycle. Both RIPK4 up or downregulation induced cell sensitivity to cisplatin, determining cell apoptosis. Conclusions In the present work we found a correlation between RIPK4 expression and TSCC degree of differentiation, age, and gender. The better understanding of the molecular mechanism of RIPK4 in TSCC may provide a promising biomarker for tongue cancer prognosis and treatment.

Authors: Erdal Aglar  , Kenan Yıldız  
Published: March 2014

This study was carried out in order to determine the effect of rootstocks (Gisela 5, Gisela 6, MaxMa 14 and SL 64) on performance of sweet cherry cultivar ‘0 900 Ziraat’ during 2010-2013 years. The trail in randomized block design was established as to factorial design. Each graft combination included 20 trees. The trees was trained as Spanish Bush training system. At the end of study, effect of rootstocks on vegetative growth was found significant. It has been determined that the trees grafted on SL 64 and MaxMa 14 rootstocks were more vigorous than the those grafted on Gisela 5 and Gisela 6. The rootstocks formed significant differences at the precocity. While the first blooming on the trees grafted on Gisela 5 and Gisela 6 rootstocks occurred at the second year after planting, the first blooming on the trees on MaxMa 14 and SL 64 rootstocks occurred at fourth year after planting. It has been determined that occur significant differences on yield per tree and yield efficiency among rootstocks. In terms of yield per tree and yield efficiency, While the lowest value was in SL 64 rootstock, the highest value was recorded in Gisela 5, and it has been determined that the differences between three rootstocks (Gisela 5, Gisela 6 and MaxMa 14) were not significant. While fruits weight varied according to the rootstock used in study, the trees grafted on Gisela 5 had the smallest fruit. Accompanied with differences between MaxMa 14 and SL 64 rootstocks were not significant, the biggest fruits were produced on trees grafted on SL 64 rootstock. As a result of the statistical analysis, it has determined that the rootstocks that used in trial did not create significant differences on soluble solids content (SSC) value. One of the most significant diagnosis was 6 % mortality rate that occurred on trees grafted Gisela 5 and Gisela 6 rootstocks.

Late Cretaceous–early Eocene Laramide uplift, exhumation, and basin subsidence in Wyoming: Crustal responses to flat slab subduction
Authors: Fan Majie , Carrapa Barbara 
Published: March 2014

AbstractLow‐angle subduction of the Farallon oceanic plate during the Late Cretaceous–early Eocene is generally considered as the main driver forming the high Rocky Mountains in Wyoming and nearby areas. How the deformation was transferred from mantle to upper crust over the great duration of deformation (~40 Myr) is still debated. Here, we reconstruct basin subsidence and compile paleoelevation, thermochronology, and provenance data to assess the timing, magnitude, and rates of rock uplift during the Laramide deformation. We reconstruct rock uplift as the sum of surface uplift and erosion constrained by combining paleoelevation and exhumation with regional stratigraphic thickness and chronostratigraphic information. The amount (and rate) of rock uplift of individual Laramide ranges was less than 2.4–4.8 km (~0.21–0.32 mm/yr) during the early Maastrichtian‐Paleocene (stage 1) and increased to more than ~3 km (~0.38–0.60 mm/yr) during the late Paleocene–early Eocene (stage 2). Our quantitative constraints reveal a two‐stage development of the Laramide deformation in Wyoming and an increase of rock uplift during stage 2, associated with enhanced intermontane basin subsidence. Exhumation and uplift during stage 1 is consistent with eastward migration of Cordilleran deformation associated with low‐angle subduction, whereas the change in exhumation during stage 2 seems to follow a southwestward trend, which requires an alternative explanation. We here suggest that the increase of rock uplift rate during the late Paleocene–early Eocene and the southwestward younging trend of uplift may be a response to the rollback and associated retreating delamination of the Farallon oceanic slab.
Influence of cloud phase composition on climate feedbacks

Published: March 2014

AbstractThe ratio of liquid water to ice in a cloud, largely controlled by the presence of ice nuclei and cloud temperature, alters cloud radiative effects. This study quantitatively examines how the liquid fraction of clouds influences various climate feedbacks using the NCAR Community Atmosphere Model (CAM). Climate feedback parameters were calculated using equilibrated temperature changes in response to increases in the atmospheric concentration of carbon dioxide in CAM Version 3.0 with a slab ocean model. Two sets of model experiments are designed such that cloud liquid fraction linearly decreases with a decrease in temperature down to −20°C (Experiment “C20”) and −40°C (Experiment “C40”). Thus, at the same subzero temperature, C20 yields fewer liquid droplets (and more ice crystals) than C40. Comparison of the results of experiments C20 and C40 reveals that experiment C20 is characterized by stronger cloud and temperature feedbacks in the tropics (30°N–30°S) (by 0.25 and −0.28 W m−2 K−1, respectively) but weaker cloud, temperature, and albedo feedbacks (by −0.20, 0.11, and −0.07 W m−2 K−1) in the extratropics. Compensation of these climate feedback changes leads to a net climate feedback change of ~7.28% of that of C40 in the model. These results suggest that adjustment of the cloud phase function affects all types of feedbacks (with the smallest effect on water vapor feedback). Although the net change in total climate feedback is small due to the cancellation of positive and negative individual feedback changes, some of the individual changes are relatively large. This illustrates the importance of the influence of cloud phase partitioning for all major climate feedbacks, and by extension, for future climate change predictions.
Unraveling the dynamics that scale cross‐shore headland relief on rocky coastlines: 1. Model development
Authors: Limber Patrick W. , Brad Murray A. , Adams Peter N. , Goldstein Evan B. 
Published: March 2014

AbstractWe have developed an exploratory model of plan view, millennial‐scale headland and bay evolution on rocky coastlines. Cross‐shore coastline relief, or amplitude, arises from alongshore differences in sea cliff lithology, where durable, erosion‐resistant rocks protrude seaward as headlands and weaker rocks retreat landward as bays. The model is built around two concurrent negative feedbacks that control headland amplitude: (1) wave energy convergence and divergence at headlands and bays, respectively, that increases in intensity as cross‐shore amplitude grows and (2) the combined processes of beach sediment production by sea cliff erosion, distribution of sediment to bays by waves, and beach accumulation that buffers sea cliffs from wave attack and limits further sea cliff retreat. Paired with the coastline relief model is a numerical wave transformation model that explores how wave energy is distributed along an embayed coastline. The two models are linked through genetic programming, a machine learning technique that parses wave model results into a tractable input for the coastline model. Using a pool of 4800 wave model simulations, genetic programming yields a function that relates breaking wave power density to cross‐shore headland amplitude, offshore wave height, approach angle, and period. The goal of the coastline model is to make simple, but fundamental, scaling arguments on how different variables (such as sea cliff height and composition) affect the equilibrium cross‐shore relief of headland and bays. The model's generality highlights the key feedbacks involved in coastline evolution and allows its equations (and model behaviors) to be easily modified by future users.

Published: March 2014

ABSTRACTA series of random polyesteramides (PEAs) based on ε‐caprolactone and glycine were synthesized by a direct melt polycondensation method. Their structure was fully characterized by NMR spectroscopy. High molar mass PEAs were obtained for glycine contents lower than 15 mol‐%. The resulting copolymers are semi‐crystalline and present increasing glass transition temperatures but decreasing melting points at increasing glycine contents. Some of these PEAs exhibit better thermal stability and higher Young's modulus and ultimate tensile strength than PCL homopolymer. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

ABSTRACTThis work presents a resonance tracking atomic force acoustic microscopy (RT‐AFAM) quantitative modulus mapping of carbon nanotubes‐reinforced acrylonitrile–butadiene–styrene polymer. RT‐AFAM average local modulus values registered were in good agreement with those measured by nanoindentation test. RT‐AFAM mapping modulus, nanoindentation, and transmission electron microscopy imaging showed that carbon nanotubes reinforcement of acrylonitrile–butadiene–styrene polymer matrix gives an elastic modulus enhancement of approximately 18.3% compared with the polymer matrix alone and showed that this technique provides high spatial resolution and helps to characterize the elastic properties of reinforced thermoplastic polymers and new compound materials at nanoscale. © 2014 Wiley Periodicals, Inc.

ABSTRACTGraphene oxide‐reinforced acrylonitrile–butadiene rubber nanocomposites were prepared via solution mixing. The morphology of the graphene oxide was studied, and its successful dispersion within the rubber matrix was confirmed by transmission electron microscopy, scanning electron microscopy, and X‐ray diffraction studies. The strong rubber‐to‐filler interaction was confirmed by swelling and mechanical reinforcing behaviors and thermal stability. Dielectric spectroscopy test indicated a marked improvement of about five times in the real part of permittivity. The electrical conductivity level was close to that of nonconductive materials. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40640.
A new convective–stratiform rainfall separation scheme
Authors: Li Xiaofan , Zhai Guoqing , Gao Shouting , Shen Xinyong 
Published: March 2014

AbstractA new convective–stratiform rainfall separation scheme is developed through combination of rain types separated by surface rainfall budget using a cloud‐resolving model simulation data during TOGA COARE. Three rain types associated with vapor convergence, upward motions throughout the troposphere, and dominant liquid microphysical processes form convective rainfall. Maximum convective rainfall requires precipitation efficiency of 100%, but it is not associated with maximum vapor convergence. Vapor and hydrometeor convergences contribute about 40% to maximum rainfall, respectively. Four rain types associated largely with hydrometeor convergence, upward motions in the upper troposphere, and dominant ice microphysical processes form stratiform rainfall.

Published: March 2014

Abstract

Background
Robotic transanal minimally invasive surgery (TAMIS) may be an option for rectum-preserving excision of neoplasms. Recent cadaveric studies showed improved vision, control and manoeuvrability compared with use of laparoscopic instruments. This study reports the clinical application.

Methods
Consecutive patients eligible for transanal endoscopic microsurgery (TEM) or TAMIS in three participating centres were operated on using a robotic platform and transanal glove port. Patient demographics, lesion characteristics, perioperative data, complications and follow-up of all patients were recorded prospectively.

Results
Sixteen patients underwent robotic TAMIS for rectal lesions with a median (range) distance from the anal verge of 8 (range 3–10) cm. The median size of the resected specimen was 5·3 (0·5–21) cm2. The median docking time and duration of operation were 36 (18–75) and 108 (40–180) min respectively. One conversion to regular (non-robotic) TAMIS was needed owing to difficulties accessing the rectum. Glove puncture necessitated replacement in four procedures, an unstable pneumorectum arose during one operation and one patient developed a pneumoperitoneum. One patient required catheterization for urinary retention. The median hospital stay was 1·3 (0–4) days. The additional cost of the robotic approach was approximately €1000 per procedure (excluding the capital expenditure on the robotic system and its maintenance).

Conclusion
Robotic TAMIS is feasible in patients with rectal lesions. Potential advantages over TEM and non-robotic TAMIS will need to be balanced against the cost of the robotic system.
