Harmful Content Detection Based on Cascaded Adaptive Boosting
Authors: Jang Seok-Woo , Lee Sang-Hong
Published: October 2018

Recently, it has become very easy to acquire various types of image contents through mobile devices with high-performance visual sensors. However, harmful image contents such as nude pictures and videos are also distributed and spread easily. Therefore, various methods for effectively detecting and filtering such image contents are being introduced continuously. In this paper, we propose a new approach to robustly detect the human navel area, which is an element representing the harmfulness of the image, using Haar-like features and a cascaded AdaBoost algorithm. In the proposed method, the nipple area of a human is detected first using the color information from the input image and the candidate navel regions are detected using positional information relative to the detected nipple area. Nonnavel areas are then removed from the candidate navel regions and only the actual navel areas are robustly detected through filtering using the Haar-like feature and the cascaded AdaBoost algorithm. The experimental results show that the proposed method extracts nipple and navel areas more precisely than the conventional method. The proposed navel area detection algorithm is expected to be used effectively in various applications related to the detection of harmful contents.

Published: October 2018

In this present work, a superhydrophobic glass surface comprising zinc oxide nanotriangles (ZnO-nt) and nontoxic silylating agent was developed via a cost-effective spray-coating technology. ZnO-nt was synthesized by a hydrothermal method. Poly(dimethylsiloxane) (PDMS) and dimethyldiethoxysilane (DMDEOS) were used as nontoxic (nonfluoro) silylating agents. The morphology and crystallinity of ZnO-nt were studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. ZnO-nt with polymeric silane (PDMS) exhibited maximum wettability as compared to nonpolymeric silane (DMDEOS). The water contact angle (WCA), sliding angle (SA), and surface roughness of ZnO-nt/PDMS-coated glass substrate under UV treatment were 165 ± 1°, 3 ± 1°, and 791 nm, respectively. The WCA of ZnO-nt/PDMS was higher (165°) than that of commercial ZnO/PDMS (ZnO-C/PDMS). ZnO-nt/PDMS was strongly attached to the glass substrate with good stability and adhesion. The reasons for improved hydrophobicity, adhesion, and mechanism of hierarchical microstructure formation on the glass substrate were explained in detail. PDMS was attached to the glass substrate via hydrogen bonds from solvated zinc acetate.
Combination of Microwave-Assisted Girard Derivatization with Ionic Liquid Matrix for Sensitive MALDI-TOF MS Analysis of Human Serum N-Glycans

Published: October 2018

We developed a new method for MALDI-TOF MS detection of N-glycans derived from human serum. The synergistic combination of microwave-assisted Girard T derivatization, solid-phase extraction desalting, and an ionic liquid matrix (2, 5-dihydroxybenzoic acid/aniline) (GT-SPE-DHB/An) allowed of more sensitive N-glycans detection than a conventional ionic liquid matrix in MALDI-TOF MS. The superior sensitivity of our method was confirmed by the number of assigned N-glycans in 900–2,000 m/z range. Using our GT-SPE-DHB/An method, we were successfully able to assign 31 glycans. However, with the established method, i.e., DHB/An method, only 15 glycans were assigned. To the best of our knowledge, this GT-SPE-DHB/An method is the first to combine cationic derivatization of N-glycan and ionic liquid matrix for N-glycan analysis in MALDI-TOF MS.

Published: October 2018

Tailor-made, linear, and “comb-like” poly(ε-caprolactone)-based copolymers were synthesized by employing a combination of controlled polymerization techniques. Poly(dimethylsiloxane-block-ε-caprolactone) copolymers (SCL#) were synthesized by a combination of anionic and ring-opening polymerization (ROP), whereas “comb-like” poly(hydroxyethylmethacrylate-co-(hydroxyethylmethacrylate-graft-ε-caprolactone)-block-ε-caprolactone) (HEMACL#) were synthesized through simultaneous ROP and reversible addition fragmentation chain transfer (RAFT) polymerization. Copolymers were characterized by hydrogen nuclear magnetic resonance (1H-NMR), size exclusion chromatography (SEC), and Fourier transform infrared (FTIR) spectroscopy. All polymers exhibited narrow molar masses distributions (Mw/Mn<1.54), and their thermal properties were analyzed by isothermal crystallization kinetics (Avrami’s theory, by using differential scanning calorimetry (DSC)) and by employing modulated thermogravimetric analysis (MTGA). The macromolecular structure exerts a noticeable effect on the PCL block behavior when compared to the PCL homopolymer, at least for the temperature range studied (16–24°C): less differences in thermal properties were observed for linear block copolymers, whereas for “comb-like” graft copolymers their final crystallization capacity strongly depends on the presence of branches. For both sets of copolymers, the decrease in the resulting melting temperatures and the increase in the half-life crystallization time values might be useful processing parameters, particularly if these copolymers are planned for using as an alternative source of 3D printing or electrospinning materials.
Atmosphere-Dependent Photoconductivity of ZnO in the Urbach Tail
Authors: Scolfaro D. , Onofre Y. J. , Teodoro M. D. , de Godoy M. P. F.
Published: October 2018

Photoconductivity is a fundamental and highly applicable phenomenon for semiconductor oxide-based devices, and the presence of defects plays a significant role in this mechanism. Here, we present an investigation based on different atmospheres and light excitation (above and below bandgap) dependences of zinc oxide thin film grown by spray-pyrolysis. As-grown ZnO presents a representative Urbach tail associated to the presence of localized levels in the bandgap. Photoconductivity response and decay times are investigated for air and inert atmospheres as well as under vacuum conditions with significant features due to light excitation conditions. The observed characteristics are explained based on oxygen photodesorption when excitation is above bandgap while this process is suppressed when excitation is below bandgap.
Two-Party Attribute-Based Key Agreement Protocol with Constant-Size Ciphertext and Key
Authors: Li Jiguo , Hu Shengzhou , Zhang Yichen
Published: October 2018

Based on mutual authentication, the session key is established for communication nodes on the open network. In order to satisfy fine-grained access control for cloud storage, the two-party attribute-based key agreement protocol (TP-AB-KA) was proposed. However, the existing TP-AB-KA protocol is high in the cost of computation and communication and is not unfit for application in a mobile cloud setting because mobile devices are generally resource constrained. To solve the above issue, we propose a TP-AB-KA protocol with constant-size ciphertext and key. Our TP-AB-KA protocol is provable security in the standard model. The concrete proof is given under the augmented multisequence of exponents' decisional Diffie-Hellman (aMSE-DDH) hypothesis in the attribute-based BJM model (AB-BJM). Compared with the existing TP-AB-KA protocols, the computation cost and communication cost of our protocol are largely reduced.

Published: October 2018

Although the use of awake flexible fiberoptic bronchoscopic (FFB) intubation is a well-recognized airway management technique in patients with difficult airway, its use in smaller children with burn contractures or in an uncooperative older child may be challenging. Herein, we report successful management of difficult airway in a 7-year-old boy with burn contracture of the neck, by application of FFB nasal intubation in a stepwise approach, first during an initial preoperative trial phase to increase patient cooperation and then during anesthesia induction for the reconstructive surgery planned for burn scars and contractures. Our findings emphasize the importance of a preplanned algorithm for airway control in secure airway management and feasibility of awake FFB intubation in a pediatric patient with burn contracture of the neck during anesthesia induction for reconstructive surgery. Application of FFB intubation based on a stepwise approach including a trial phase prior to operation day seemed to increase the chance of a successful intubation in our patient in terms of technical expertise and increased patient cooperation and tolerance by enabling familiarity with the procedure.
Evolutionary Game Dynamics for Financial Risk Decision‐Making in Global Supply Chain
Authors: Li Zhi , Jin Guanghao , Duan Shen
Published: October 2018

This paper focuses on the game evolution process and its influencing factors of financial risk cooperation behavior between suppliers and manufacturers in global supply chain system. Using two‐population evolutionary game theory, the performance of supply chain members under financial risk environment is modeled. Further, the proposed financial risk game model is applied to simulation cases of global supply chain. Based on the theory analysis and simulation results, it is shown that the cooperation strategy is the optimal evolutionarily stable strategy (ESS) for all supply chain members, when facing the high financial risk. The financial risk‐sharing coefficient can be regarded as an adjuster that affects risk ESS of both suppliers and manufacturers under the low financial risk setting. By reducing the financial risk‐sharing ratio of one supply chain player, his intention of adopting cooperation strategy would be enhanced. Finally, it is observed that financial risk sharing approach may lead to the alignment among supply chain members. Therefore, setting up an effective financial risk‐sharing mechanism is beneficial to realize sustainable development of global supply chain.

Authors: Xu Bing , Wu Fahong , Xu Guizhong
Published: October 2018

In order to limit the disengaging of short square concrete‐filled steel tube (CFST) columns and strengthen the combined action of steel tubes and concrete, a reinforcing method of stiffener is put forward in this paper. The axial compression performance and mechanism are studied through experiments, which indicate that (1) the buckling model of stiffening members changes into double wave, (2) stiffeners enforce the constraint in core concrete, (3) stiffeners can effectively improve the ultimate bearing capacity, (4) the stiffeners increase the stress in the middle of the steel tube and improve the distribution of stress for the core concrete, and (5) the direct ribs have more influence on the bearing capacity while ribs with holes have more impact on the deformation of the tube. At the end of the article, a formula for calculating the ultimate bearing capacity is presented, which can bring out a more accurate bearing capacity value.
Experimental Research on Microstructure and Physical‐Mechanical Properties of Expansive Soil Stabilized with Fly Ash, Sand, and Basalt Fiber
Authors: Ma Qin-yong , Cao Zi-ming , Yuan Pu
Published: October 2018

Expansive soil is a source of risk to the foundations or subgrade engineering. Stabilization of expansive soil is imperative for practical engineering. A series of laboratory experiments were performed to analyze the physical‐mechanical properties and microstructures of stabilized soil. Three stabilizers used in this study are fly ash, sand, and basalt fiber. Different percentages of fly ash (0, 5, 10, 15, and 20%), sand (0, 8, 16, and 24%), and basalt fiber (0 and 0.4%) were added by weight into natural soil. Experimental results indicate that the optimum moisture content of stabilized soil increases with the increase of fly ash content for a given sand content, whereas the maximum dry density shows a decreasing trend. The variation trend of optimum moisture content and maximum dry density turns reverse with the increase of sand content for a given fly ash content. Plasticity index is decreased by both increasing fly ash content and sand content. It is found that the maximum unconfined compressive strength and optimum growth rate of strength are obtained by selected mixtures of 10% fly ash, 8% sand, and 0.4% basalt fiber contents. As the analysis of complementary effect suggests, most of the mixt treatments applied in this study have produced good results associated with the strength enhancement of expansive soil. In line with the results of SEM tests, the connection among clay particles has been enhanced through the generation of hydration products (C‐S‐H and AFt) of fly ash. The filling effect of sand has increased the integrality and compactness of stabilized soil. Moreover, the gripping effect between fibers and soil particles notably improves the strength of stabilized soil. The effect of sand on reinforced soil with 0.4% basalt fiber increases the interfacial force between fibers and soil particles.
Rotor Blades Diagnosis Method Based on Differences in Phase Shifts
Authors: Grądzki Rafał , Lindstedt Paweł , Kulesza Zbigniew , Bartoszewicz Błażej
Published: October 2018

In this work, an innovative diagnosis method of rotor blades is presented. A measurement signal of blade tip displacement is divided into two observation zones, in which two peaks of an additional template signal are introduced. Cross‐correlation and power spectral density functions of the measurement and template signals in these two distinct zones are calculated. Next, the phase shift between the two cross‐correlation functions is obtained by calculating the ratio of the two power spectral density functions. The changes in parameters of an analytical description of this phase shift are used to determine a distinct and easy‐to‐analyze image of the technical condition of the tested blade. A graphical portrait indicating the technical condition of all blades in the annulus is developed. Although not directly measured, environmental signals (e.g., external disturbances and sensor’s noise) affecting the diagnostic process are included in the method. It is demonstrated that, by using the proposed signal processing technique, a negative influence of these disturbances is eliminated and the reliability of the machine technical condition indications is improved. The approach is demonstrated using experimental results of turbine engine blade displacements. High effectiveness of the method and measurement equipment has been confirmed in a wide range of analyzed tip‐timing results obtained in different periods of the measurement process.

Objective. To investigate the relationship between weight gain in pregnancy and postpartum depression (PPD) in normal and overweight pregnant women. Methods. The participants of this prospective cohort study were 223 healthy pregnant women with the first trimester body mass index (BMI) between 18.5 and 30 and the gestational age of 10-14 weeks and depressed women were excluded with Beck questionnaire in the first trimester. The evaluation included weight gain at the end of the second and third trimesters and the screening of PPD in 6-8 weeks after delivery by Edinburgh scale. Results. 49 participants were excluded from the study and data from 174 people were analyzed. 32.2% of mothers were scored above 12 in the Edinburgh scale. The only variable associated with depression was the third trimester weight gain (OR 1.17, 95%CI 1.04-1.32). Conclusion. In addition to considering other risk factors for postpartum depression, health care providers should consider the higher probability of PPD in prepregnancy normal and overweight women who have excessive weight gain especially in the third trimester of pregnancy.
Multiple Equilibrium Behaviors considering Human Exposure to Vehicular Emissions
Authors: Sun Zhanbo , Tan Yu , Ma Rui , Yang Xia , Zhang Jie
Published: October 2018

Emissions produced by urban transportation activities are harmful to people’s health and they also affect people’s trip-making decisions. In this paper, we explore the multiple equilibrium behaviors considering human exposure to vehicular emissions. We assume that a portion of transportation users are environmental advocates and their route decisions are based on some composite cost functions comprise of a travel time component and an emission exposure component. We then study the multiple equilibrium behaviors with multiple types of users on a traffic network. The multiple equilibrium problems are further converted into variational inequality (VI) problems and they are solved using a method of successive average- (MSA-) based diagonalization method. Per the specific network setting, we find that as travelers become more concerned about their exposure to vehicular emissions, the system emission exposure, travel time, and the total cost get reduced; i.e., Pareto improving solutions are achieved. By analyzing the multiple equilibrium behaviors, we find that the system gets better if more users become environmental advocates. And the change of a small percentage of users should already lead to a good system improvement.
Can Scalable Design of Wings for Flapping Wing Micro Air Vehicle Be Inspired by Natural Flyers?
Authors: Nan Yanghai , Peng Bei , Chen Yi , Feng Zhenyu , McGlinchey Don
Published: October 2018

Lift production is constantly a great challenge for flapping wing micro air vehicles (MAVs). Designing a workable wing, therefore, plays an essential role. Dimensional analysis is an effective and valuable tool in studying the biomechanics of flyers. In this paper, geometric similarity study is firstly presented. Then, thepw−ARratio is defined and employed in wing performance estimation before the lumped parameter is induced and utilized in wing design. Comprehensive scaling laws on relation of wing performances for natural flyers are next investigated and developed via statistical analysis before being utilized to examine the wing design. Through geometric similarity study and statistical analysis, the results show that the aspect ratio and lumped parameter are independent on mass, and the lumped parameter is inversely proportional to the aspect ratio. The lumped parameters and aspect ratio of flapping wing MAVs correspond to the range of wing performances of natural flyers. Also, the wing performances of existing flapping wing MAVs are examined and follow the scaling laws. Last, the manufactured wings of the flapping wing MAVs are summarized. Our results will, therefore, provide a simple but powerful guideline for biologists and engineers who study the morphology of natural flyers and design flapping wing MAVs.

Pequi (Caryocar brasiliense) is an endemic species from Brazilian Cerrado, and their fruits are widely used in regional cuisine. In this work, a crude hydroalcoholic extract (CHE) of C. brasiliense leaves and its resulting fractions in hexane (HF), chloroform (CF), ethyl acetate (EAF), and butanol (BF) were investigated for their antioxidant properties and anticholinesterase activities. The antioxidant properties were evaluated by free radical scavenging and electroanalytical assays, which were further correlated with the total phenolic content and LC‐MS results. The acetylcholinesterase and butyrylcholinesterase inhibitory activities were examined using Ellman’s colorimetric method. The LC‐MS analysis of EAF revealed the presence of gallic acid and quercetin. CHE and its fractions, EAF and BF, showed anticholinesterase and antioxidant activities, suggesting the association of both effects with the phenolic content. In addition, behavioral tests performed with CHE (10, 100, and 300 mg/kg) showed that it prevented mice memory impairment which resulted from aluminium intake. Moreover, CHE inhibited brain lipid peroxidation and acetyl and butyryl‐cholinesterase activities and the extract’s neuroprotective effect was reflected at the microscopic level. Therefore, the leaves of pequi are a potential source of phenolic antioxidants and can be potentially used in treatments of memory dysfunctions, such as those associated with neurodegenerative disorders.
Social workers and alienation: the compassionate self and the disappointed juggler
Authors: Yuill Chris
Published: October 2018

British social work has been undergoing a series of radical transformations from the 1980s onwards. The main shift has been a move away from the parochial professionalism of the 1970s to a profession that is being constantly reshaped by the impulses of new managerialism to meet the needs of the neoliberal state. From the vantage point of Marxian alienation theory, this article analyses the experiences of 16 social workers of being alienated and estranged from how they desire their labour to be. The main finding to emerge from the qualitative semi-structured interviews is that the logics of new managerialism lead to a loss of the object of labour (the service user) by substituting that object with another: the case report. That report requires none of the creativity and skills that the social workers wish to exercise in their labour. Instead, it dominates and structures their work while distorting their subjectivity.
Social work, neoliberalism and authoritarianism: an analysis of the policy document ‘Regulating social workers’
Authors: Gwilym Hefin
Published: October 2018

This discussion examines the complexity of the social work profession in the neoliberal era. Government austerity policies and a market and corporate neoliberal state have effectively trapped social work in an ideology that increasingly furthers the authoritarian nature of the profession. This will be discussed by looking at the broader policy, political and economic contexts. It will focus in detail on one specific Conservative government policy document, namely, ‘Regulating social workers’ (DoE and DH, 2016).

Published: October 2018

Resumen: El objetivo de este estudio fue explorar las actitudes hacia el aborto inducido en jóvenes mexicanos, y su relación con el hecho de considerar o no al aborto inseguro un problema de salud pública. Los resultados se compararon de acuerdo al sexo, edad, religión y disciplina de los participantes. La muestra estuvo integrada por 411 estudiantes universitarios, quienes contestaron el cuestionario sobre actitudes hacia el aborto y un cuestionario sobre aborto inseguro. Los participantes mostraron actitudes más favorables que condenatorias hacia el aborto inducido. En general, reconocieron que el aborto inseguro constituye un riesgo para la salud, pero no están seguros que su legislación ayude a resolver esta situación. Los hombres y los participantes religiosos (católicos u otra religión derivada del cristianismo) tuvieron actitudes más condenatorias hacia el aborto inducido que sus pares, y fueron los que menos consideran que legalizar el aborto pueda disminuir los problemas de salud que ocasiona el aborto inseguro. No hubo diferencias relacionadas con la edad de los participantes, ni con su disciplina. Un hallazgo preocupante fue el poco interés de los jóvenes en el tema de la legalización del aborto.

Abstract: Although it is well known that a successful implementation depends on the front-liners’ knowledge and participation, as well as on the organizational capacity of the institutions involved, we still know little about how front-line health workers have been involved in the implementation of the Brazilian National Program for Improving Access and Quality to Primary Care (PMAQ). This paper develops a contingent mixed-method approach to explore the perceptions of front-line health workers - managers, nurses, community health workers, and doctors - regarding the PMAQ (2nd round), and their evaluations concerning health unit organizational capacity. The research is guided by three relevant inter-related concepts from implementation theory: policy knowledge, participation, and organizational capacity. One hundred and twenty-seven health workers from 12 primary health care units in Goiânia, Goiás State, Brazil, answered semi-structured questionnaires, seeking to collect data on reasons for adherence, forms of participation, perceived impact (open-ended questions), and evaluation of organizational capacity (score between 0-10). Content analyses of qualitative data enabled us to categorize the variables “level of perceived impact of PMAQ” and “reasons for adhering to PMAQ”. The calculation and aggregation of the means for the scores given for organizational capacity enabled us to classify distinct levels of organizational capacity. We finally integrated both variables (Perceived-Impact and Organizational-Capacity) through cross-tabulation and the narrative. Results show that nurses are the main type of professional participating. The low organizational capacity and little policy knowledge affected workers participation in and their perceptions of the PMAQ.

O estabelecimento de metas universais voltadas ao controle do HIV/aids e a instituição do tratamento como forma de prevenção reforçam a necessidade do acompanhamento clínico continuado das pessoas vivendo com HIV/aids como um elemento indispensável ao cuidado destas, sendo a retenção no cuidado em saúde uma necessidade e um desafio. Neste estudo, objetivou-se construir um modelo preditivo de retenção de pessoas vivendo com HIV/aids no cuidado em saúde. Para tanto foi construído um modelo estatístico, árvore de decisão, com base em variáveis sociodemográficas, clínicas e relacionadas aos comportamentos em saúde, identificadas em um banco de dados que contemplava informações de 260 pessoas com HIV/aids, vinculadas a um serviço especializado no atendimento a estes indivíduos. O modelo subsidiou a identificação de nove variáveis cujos ganhos de informação foram significativos em relação à variável desfecho, provável retenção no cuidado em saúde, e à construção de 24 regras de decisão, dando origem a uma árvore com porcentual de acerto de 80,4%, as quais poderão contribuir com a identificação de possíveis estratégias no sentido de otimizar a retenção e contribuir com o alcance das metas propostas para o enfrentamento da epidemia nos próximos anos.

RESUMO: O uso de indicadores para dimensionar desigualdades sociais tem se disseminado de forma mais intensa nas últimas décadas em estudos da área das ciências humanas. Trazer esse instrumental para a análise das mudanças ocorridas na participação de mulheres e negros nos cursos de graduação e pós-graduação, tem considerável importância em face da implementação de políticas de ação afirmativa que objetivaram a ampliação do acesso ao ensino superior de grupos sociais sub-representados, em especial os negros e indígenas. Este estudo apresenta os índices de Paridade de Gênero (IPG) e Paridade Racial (IPR) como instrumentos auxiliares na caracterização do público que acessou e frequentou a graduação e pós-graduação no período 2000-2010, a partir das informações fornecidas pelos Censos Demográficos de 2000 e 2010. Observa-se, nos resultados obtidos, que o acesso é tanto diferenciado por sexo como por cor/raça, com piores indicadores para os negros.

As buscas foram realizadas nas bases SciELO e Scopus, do período de 1997 a 2017, tendo as finalidades específicas de mapear os dados, por meio de gráficos, além de refinar os resultados para uma análise profícua das publicações. A partir dos resultados, foi possível confirmar a escassez de trabalhos nacionais e internacionais que contribuam com reflexões para uma formação docente no âmbito de uma cultura digital. Apesar de iniciativas interessantes de estudo das mídias, há a prevalência, nos cursos, de noções direcionadas ao uso das tecnologias no ensino, com ênfase disciplinar. As perspectivas críticas e criativas de leitura e produção em mídias são pouco exploradas. Assim, defende-se a Midiaeducação como um âmbito formativo fundamental para o exercício de uma cidadania ativa.
EM LETRAS E RITMOS: VISÕES DE ESCOLA, EDUCAÇÃO E TRABALHO NO SAMBA BRASILEIRO (1930-1950)
Authors: SALVADORI MARIA ANGELA BORGES
Published: October 2018

RESUMO: Este artigo analisa o modo como questões ligadas ao analfabetismo, escola, educação e experiência foram tratadas em canções compostas por sambistas brasileiros que se autodenominavam “malandros”. Dialogando com a história social inglesa, particularmente com os trabalhos de E. P. Thompson, considera que este cancioneiro constitui fonte histórica que permite o acesso a formas de pensar e sentir dos grupos populares quanto à escola e à educação, especialmente entre os anos 1930 e 1950, período em que esses sambas alcançaram sucesso por meio do rádio. Conclui que essas composições, mesmo tematizando sujeitos ou situações singulares, foram exercícios sonoros de crítica social e educação política, com a constância de certas tópicas: denúncia das desigualdades educacionais e escolares e do preconceito contra o analfabeto, conflito entre cultura letrada e cultura popular e, por fim, uma postura anti-intelectualista que desdenhava dos saberes escolares vistos como pouco úteis diante das urgências da vida cotidiana.
FUNDAMENTAÇÃO TEÓRICA DA EDUCAÇÃO FÍSICA EM PROPOSTAS CURRICULARES DA ESCOLA PÚBLICA DE SÃO PAULO: UMA ANÁLISE DAS ABORDAGENS PEDAGÓGICAS

RESUMO: O objetivo desse estudo foi analisar as orientações curriculares da Educação Física (EF) na rede municipal e estadual de São Paulo com vistas a identificar as concepções teóricas que influenciaram sua elaboração. Foram analisadas quatro propostas curriculares da rede estadual e seis documentos oficiais curriculares da rede municipal publicados entre o final da década de 1970 e o ano de 2017. Essa análise mostrou que houve publicações de orientações curriculares durante todo o período pesquisado e que é permanente a intenção de influenciar a prática pedagógica do professor de EF. No entanto, foram notadas mudanças bruscas na forma como era proposto o ensino no interior da escola. Ficou claro que a tematização das manifestações da cultura corporal de movimento se tornou o objetivo hegemônico nas orientações curriculares publicadas na última década, de modo a caracterizar uma superação do paradigma da aptidão física como norteador da prática pedagógica.
REPOLITIZAR O SOCIAL E TOMAR DE VOLTA A LIBERDADE
Authors: MACEDO ELIZABETH
Published: October 2018

RESUMO: Busco entender as articulações que tornam possível que um conjunto de demandas localizadas, trazidas à cena pelo Escola sem Partido, um grupo sem óbvia representatividade na sociedade, ganhe espaço na recente política educacional no Brasil. Em um primeiro momento, são mapeadas articulações entre o movimento, grupos religiosos conservadores e a Rede Atlas, mobilizando a teoria do discurso de Laclau e Mouffe e a noção de redes globais utilizada por Ball. Defendo que tal articulação vem contribuindo para a hegemonização das posições do ESP. Em um segundo momento, em diálogo com a leitura do neoliberalismo como economização da vida, de Brown, levanto hipóteses para entender a relevância das demandas conservadoras para a normatividade neoliberal. Com Laclau, argumento que há uma luta pela representação do povo, que põe em oposição as políticas populistas dos governos do PT e a rede constituída pela articulação entre a Rede Atlas e o Escola sem Partido.
A BNCC DA REFORMA DO ENSINO MÉDIO: O RESGATE DE UM EMPOEIRADO DISCURSO
Authors: SILVA MONICA RIBEIRO DA
Published: October 2018

RESUMO: Neste texto nos ocupamos da reforma do ensino médio, com destaque para a produção da Base Nacional Comum Curricular BNCC). O objetivo é mostrar que, por trás de um discurso apresentado como ‘novo”, as propostas da reforma e de sua BNCC compõem um velho discurso e reiteram finalidades sufocadas pelas disputas em torno dos sentidos e finalidades que envolvem esta etapa da educação básica nos últimos 20 anos. Dentre as conclusões, se evidencia que a centralidade conferida à noção de competências no documento recupera o discurso presente nos textos de políticas curriculares do final da década de 90 e reintroduz os limites já identificados em pesquisas anteriores, dentre eles, o de que tal abordagem mostra-se limitada por seu caráter pragmático e a-histórico.
«Ici c’est une copropriété, c’est pas la pagaille»: Les copropriétés populaires du PAC/PMCMV comme instrument de nettoyage moral pour d’anciens habitants des favelas
Authors: Conceição Wellington da Silva
Published: October 2018

Résumé Cet article présente les résultats d’une enquête sur les copropriétés construites à la fois par l’état et la municipalité de Rio de Janeiro pour y reloger les habitants de favelas, dans le cadre de programmes tels que le PAC et Morar Carioca [Habiter Carioca], souvent dans des programmes résidentiels du programme Minha Casa, Minha vida - MCMV. Pendant mon travail de terrain ethnographique, j’ai pu remarquer que les habitants employaient différemment la typologie de « copropriété » : partant de son insertion dans l’imaginaire de la ville en tant que lieu de résidence des groupes les plus aisés, ces nouveaux copropriétaires mobilisaient cette représentation dans la construction de leurs projets de nettoyage moral, comme une manière de se dégager du stigmate d’habitant de favela. La recherche du nettoyage de l’image n’impliquait pas d’abandonner les pratiques des favelas : on observe des comportements et des utilisations des espaces contrastant avec le modèle de la copropriété, ce qui permet à de gens de l’extérieur et de l’intérieur d’utiliser le terme de « favelado » [habitant de favela] en tant que catégorie d’accusation. Et toujours pour échapper à la stigmatisation, les habitants mettent en œuvre trois stratégies de nettoyage moral: la redirection du stigmate, la personnalisation des règles et l’esthétique de la distinction.
Promover o Raciocínio Matemático dos Alunos: uma investigação baseada em design
Authors: Mata-Pereira Joana , Ponte João Pedro da
Published: October 2018

Resumo O modo de promover o raciocínio matemático dos alunos é uma questão importante, mas pouco investigada. Este artigo apresenta o primeiro ciclo de intervenção de uma investigação baseada em design (IBD) sobre a promoção do raciocínio matemático dos alunos. Tem por objetivo compreender de que modo um conjunto de princípios de design referentes às tarefas a propor e às ações do professor na sala de aula pode contribuir para promover o raciocínio matemático dos alunos. A análise de dados tem por base estes princípios de design e centra-se, essencialmente, nos processos de raciocínio dos alunos de generalizar e justificar e nas ações do professor de convidar, guiar, sugerir e desafiar. Os resultados sugerem que os princípios de design contribuem para que os processos de raciocínio dos alunos se evidenciem nos momentos de discussão coletiva de tarefas de natureza exploratória.
¿Qué Estructuras Deductivas Usan Alumnos Ingresantes a la Universidad?
Authors: Apud Eduardo Mario Lacues , Moreno Leonora Díaz , Martinez Juan Antonio Huertas
Published: October 2018

Resumen En este trabajo se presentan resultados de una indagación que inquirió el efecto que, sobre estudiantes ingresantes a la universidad, tuvieron cursos universitarios iniciales de Matemática para adquirir conocimientos que faciliten la comprensión y el uso de estructuras deductivas de uso frecuente en razonamientos o argumentaciones. Este tema es de interés actual en Uruguay, debido a la preocupación que generan las altas tasas de rezago y abandono en primer año. Como antecedentes se efectuó un análisis de libros de texto usuales y de registros estudiantiles de clases, en busca de evidencias acerca del grado de explicitación de estas estructuras en la enseñanza. Entre los resultados observados destacan que los ingresantes muestran conocimientos acerca de las estructuras deductivas para comprender o construir razonamientos, y que la sola participación en cursos de Matemática, sin mediar una enseñanza intencional, no parece suficiente para adquirir habilidades en esta área.
El Plano Cartesiano en estudiantes de Quinto Básico: su Resignificación en una Situación Específica
Authors: Aravena Angélica , Morales Astrid
Published: October 2018

Resumen Se presentan los resultados de una investigación relativa a la resignificación del plano cartesiano en un grupo de estudiantes de quinto básico de una escuela chilena. El discurso matemático escolar correspondiente carece de situaciones de enseñanza significativas para introducir y comprender el uso de ese plano, más bien fomenta una matemática prescrita, donde no es necesaria su construcción. Desde un enfoque cualitativo, a través de la indagación del proceso de construcción de un conocimiento matemático, la resignificación se evidencia a través del diseño de una situación específica que promueve la necesidad de la construcción del plano cartesiano. En los argumentos y discusión sostenidos por el grupo de estudiantes se evidenció la construcción de ejes ortogonales, las nociones de distancia, origen y ubicación de puntos considerando coordenadas rectangulares.

Published: October 2018

Resumen Este trabajo da cuenta de la organización y estructura del resultado de la respuesta observada sobre tablas estadísticas en estudiantes de Educación Primaria de escuelas municipalizadas en la provincia de Osorno-Chile. Se aplicó una prueba con cuatro preguntas abiertas a una muestra de 233 estudiantes de tercero y sexto nivel. Las respuestas fueron clasificadas según un continuo que va desde la incompetencia a la maestría: la capacidad, operaciones implicadas, consistencia y conclusiones. Los resultados muestran que las respuestas de los estudiantes se agrupan, mayoritariamente, en el enfoque de aprendizaje superficial, esto significa que, aunque entrega datos relevantes lo hace en forma aislada, los ordenan pero, falla en la conexión entre ellos. Se observó que no hay diferencias significativas entre la estructura y organización de las respuestas que elaboran los estudiantes de tercero y sexto año.
Crianças do Pré-Escolar a Resolver Problemas de Estrutura Aditiva: Que estratégias?
Authors: Soutinho Florbela , Mamede Ema
Published: October 2018

Resumo Os estudos desenvolvidos em diferentes contextos ressaltam a capacidade que as crianças têm de resolver corretamente problemas de adição e subtração, antes ainda destas operações lhes serem formalmente ensinadas. O estudo aqui descrito procura perceber como as crianças dos 4 aos 6 anos (N=90) entendem os problemas de estrutura aditiva. Para tal, tenta responder às seguintes questões: 1) Que desempenhos apresentam as crianças quando resolvem problemas de estrutura aditiva? 2) Que estratégias usam para resolver os problemas de estrutura aditiva? Adotou-se uma metodologia quantitativa que analisa os desempenhos e as estratégias das crianças quando resolvem 28 problemas de estrutura aditiva, apresentados a partir de entrevistas estruturadas individuais. Os resultados sugerem que as crianças resolvem com facilidade os problemas propostos e utilizam estratégias adequadas para responderem corretamente, chegando mesmo a recorrer a estratégias abstratas como a contagem e os fatos numéricos.
