The Dynamical Behavior of a Rigid Body Relative Equilibrium Position
Authors: Amer T. S.
Published: March 2017

In this paper, we will focus on the dynamical behavior of a rigid body suspended on an elastic spring as a pendulum model with three degrees of freedom. It is assumed that the body moves in a rotating vertical plane uniformly with an arbitrary angular velocity. The relative periodic motions of this model are considered. The governing equations of motion are obtained using Lagrange’s equations and represent a nonlinear system of second-order differential equations that can be solved in terms of generalized coordinates. The numerical solutions are investigated using the fourth-order Runge-Kutta algorithms through Matlab packages. These solutions are represented graphically in order to describe and discuss the behavior of the body at any instant for different values of the physical parameters of the body. The obtained results have been discussed and compared with some previous published works. Some concluding remarks have been presented at the end of this work. The importance of this work is due to its numerous applications in life such as the vibrations that occur in buildings and structures.

Published: March 2017

The increasing average age of the population in most industrialized countries imposes a necessity for developing advanced and practical services using state-of-the-art technologies, dedicated to personal living spaces. In this paper, we introduce a hierarchical distributed approach for home care systems based on a new paradigm known as Internet of Things (IoT). The proposed generic framework is supported by a three-level data management model composed of dew computing, fog computing, and cloud computing for efficient data flow in IoT based home care systems. We examine the proposed model through a real case scenario of an early fire detection system using a distributed fuzzy logic approach. The obtained results prove that such implementation of dew and fog computing provides high accuracy in fire detection IoT systems, while achieving minimum data latency.

Published: March 2017

A simple and sensitive HPLC‐UV method has been developed for the simultaneous determination of quercetin, luteolin, and apigenin in rat plasma after oral administration of Matricaria chamomilla L. extract. The flow rate was set at 1.0 ml/min and the detection wavelength was kept at 350 nm. The calibration curves were linear in the range of 0.11–11.36 μg/ml for quercetin, 0.11–11.20 μg/ml for luteolin, and 0.11–10.60 μg/ml for apigenin, respectively. The intraday and interday precisions (RSD) were less than 8.32 and 8.81%, respectively. The lower limits of quantification (LLOQ) of the three compounds were 0.11 μg/ml. The mean recoveries for quercetin, luteolin, and apigenin were 99.11, 95.62, and 95.21%, respectively. Stability studies demonstrated that the three compounds were stable in the preparation and analytical process. The maximum plasma concentration (Cmax) was 0.29 ± 0.06, 3.04 ± 0.60, and 0.42 ± 0.10 μg/ml, respectively. The time to reach the maximum plasma concentration (Tmax) was 0.79 ± 0.25, 0.42 ± 0.09, and 0.51 ± 0.13 h, respectively. The validated method was successfully applied to investigate the pharmacokinetics study of quercetin, luteolin, and apigenin in rat plasma after oral administration of M. chamomilla extract.
An Enhanced-Solvent Deasphalting Process: Effect of Inclusion of SiO2Nanoparticles in the Quality of Deasphalted Oil
Authors: Guzmán Juan D. , Franco Camilo A. , Cortés Farid B.
Published: March 2017

In this work, the effect of nanoparticles in deasphalting heavy oil and extra-heavy oil process at laboratory-scale based on the conventional solvent deasphalting process was studied and named enhanced-solvent deasphalting (e-SDA) process. This work evaluated the effect of the nanoparticles of SiO2in the separation efficiency based on deasphalted oil (DAO) fraction quality compared to the conventional process of deasphalting (SDA). Different effects have been assessed such as solvent to oil ratio, operating temperatures, type of solvent, and SiO2nanoparticles dosage. The DAO quality was based on the asphaltene and sulfur contents, API gravity, distillable fraction, and rheological properties. The improvement of the process from the use of nanoparticles was confirmed with important reductions in the asphaltene and sulfur contents in the DAO of up to 24% and 23%, respectively, in comparison with the SDA process. Also, the API gravity can be increased by approximately 14% with thee-SDA process. The rheological properties of the DAO were improved by the inclusion of nanoparticles showing reductions in the viscosities of the DAO greater than 50% in comparison with the conventional process. These results lead to the conclusion that thee-SDA process improves the DAO quality when compared with the typical deasphalting process.

Published: March 2017

Purpose: High levels of ROS and ineffective antioxidant systems contribute to oxidative stress, which affects the function of hematopoietic cells in acute myeloid leukemia (AML); however, the mechanisms by which ROS lead to malignant transformation in relapsed AML-M5 are not completely understood. We hypothesized that alterations in intracellular ROS would trigger AML-M5 relapse by activating the intrinsic pathway.

Experimental Design: We studied ROS levels and conducted c-Jun activation domain–binding protein-1 (JAB1/COPS5) and thioredoxin (TRX) gene expression analyses with blood samples obtained from 60 matched AML-M5 patients at diagnosis and relapse and conducted mechanism studies of Jab1′s regulation of Trx in leukemia cell lines.

Results: Our data showed that increased production of ROS and a low capacity of antioxidant enzymes were characteristics of AML-M5, both at diagnosis and at relapse. Consistently, increased gene expression levels of TRX and JAB1/COPS5 were associated with low overall survival rates in patients with AML-M5. In addition, stimulating AML-M5 cells with low concentrations of hydrogen peroxide led to increased Jab1 and Trx expression. Consistently, transfection of ectopic Jab1 into leukemia cells increased Trx expression, whereas silencing of Jab1 in leukemia cells reduced Trx expression. Mechanistically, Jab1 interacted with Trx and stabilized Trx protein. Moreover, Jab1 transcriptionally regulated Trx. Furthermore, depletion of Jab1 inhibited leukemia cell growth both in vitro and in vivo.

Conclusions: We identified a novel Jab1–Trx axis that is a key cellular process in the pathobiologic characteristics of AML-M5. Targeting the ROS/Jab1/Trx pathway could be beneficial in the treatment of AML-M5. Clin Cancer Res; 23(15); 4450–61. ©2017 AACR.

Purpose: Cyclin-dependent kinase (CDK) 4/6 drives cell proliferation in estrogen receptor–positive (ER+) breast cancer. This single-arm phase II neoadjuvant trial (NeoPalAna) assessed the antiproliferative activity of the CDK4/6 inhibitor palbociclib in primary breast cancer as a prelude to adjuvant studies.

Experimental Design: Eligible patients with clinical stage II/III ER+/HER2− breast cancer received anastrozole 1 mg daily for 4 weeks (cycle 0; with goserelin if premenopausal), followed by adding palbociclib (125 mg daily on days 1–21) on cycle 1 day 1 (C1D1) for four 28-day cycles unless C1D15 Ki67 > 10%, in which case patients went off study due to inadequate response. Anastrozole was continued until surgery, which occurred 3 to 5 weeks after palbociclib exposure. Later patients received additional 10 to 12 days of palbociclib (Cycle 5) immediately before surgery. Serial biopsies at baseline, C1D1, C1D15, and surgery were analyzed for Ki67, gene expression, and mutation profiles. The primary endpoint was complete cell cycle arrest (CCCA: central Ki67 ≤ 2.7%).

Results: Fifty patients enrolled. The CCCA rate was significantly higher after adding palbociclib to anastrozole (C1D15 87% vs. C1D1 26%, P < 0.001). Palbociclib enhanced cell-cycle control over anastrozole monotherapy regardless of luminal subtype (A vs. B) and PIK3CA status with activity observed across a broad range of clinicopathologic and mutation profiles. Ki67 recovery at surgery following palbociclib washout was suppressed by cycle 5 palbociclib. Resistance was associated with nonluminal subtypes and persistent E2F-target gene expression.

Conclusions: Palbociclib is an active antiproliferative agent for early-stage breast cancer resistant to anastrozole; however, prolonged administration may be necessary to maintain its effect. Clin Cancer Res; 23(15); 4055–65. ©2017 AACR.

Published: March 2017

Background: Since 2012, Associated Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) has been standing in the limelight of modern liver surgery and numerous questions have been raised regarding this novel approach. On the one hand, ALPPS has proved to be a valuable method in the treatment of hepatic tumors, while on the other hand, there are many controversies, such as high mortality and morbidity rates. Further surgical research is essential for a better understanding of underlying mechanisms and for enhancing patient safety. Summary: Until recently, only 8 animal models have been created with the purpose to mimic ALPPS-induced liver regeneration. From these 7 are rodent (6 rat and 1 mouse) models, while only 1 is a large animal model, which uses pigs. In case of rodent models, portal flow deprivation of 75-90% is achieved via portal vein ligation leaving only the right (20-25%) or left median (10-15%) lobes portally perfused, while liver splitting in general is carried out positioned according to the falciform ligament. As for the swine model, the left lateral and medial lobes (70-75% of total liver volume) are portally ligated, and the right lateral lobe (accounting for 20-24% of the parenchyma) is partially resected in order to reach critical liver volume. Each model is capable of reproducing the accelerated liver regeneration seen in human cases. However, all species have significantly different liver anatomy compared with the human anatomic situation, making clinical translation somewhat difficult. Key Messages: Unfortunately, there are no perfect animal models available for ALPPS research. Small animal models are inexpensive and well suited for basic research, but may only provide limited translational potential to humans. Clinically large animal models may provide more relevant data, but currently no suitable one exists.
Sex-Specific Transcript Diversity in the Fly Head Is Established during Pupal Stages and Adulthood and Is Largely Independent of the Mating Process and the Germline
Authors: Mohr Carmen , Kleiner Sarah , Blanchette Marco , Pyrowolakis George , Hartmann Britta
Published: March 2017

Alternative splicing (AS), the process which generates multiple RNA and protein isoforms from a single pre-mRNA, greatly contributes to transcript diversity and compensates for the fact that the gene number does not scale with organismal complexity. A number of genomic approaches have established that the extent of AS is much higher than previously expected, raising questions on its spatio-temporal regulation and function. In the present study, we address AS in the context of sex-specific neuronal development in the model Drosophila melanogaster. We report that at least 47 genes display sex-specific AS in the adult fly head. Unlike targets of the classical Sex lethal-dependent sex determination cascade, sex-specific isoforms of the vast majority of these genes are not present during larval development but start accumulating during metamorphosis or later, indicating the existence of novel mechanisms in the induction of sex-specific AS. We also established that sex-specific AS in the adult fly head is largely independent of the germline or the mating process. Finally, we investigated the role of sex-specific AS of the sulfotransferase Tango13 pre-mRNA and provide first evidence that differential expression of certain isoforms of this protein significantly affects courtship and mating behavior in male flies.
Large Duplications Can Be Benign Copy Number Variants: A Case of a 3.6-Mb Xq21.33 Duplication

Published: March 2017

Segmental aneusomies are usually associated with clinical consequences, but an increasing number of nonpathogenic cytogenetically visible as well as large cryptic chromosomal imbalances have been reported. Here, we report a 3.6-Mb Xq21.33 microduplication detected prenatally on a female fetus which was inherited from a phenotypically normal mother and grandfather. It is assumed that male patients harboring Xq or Xp duplication present with syndromic intellectual disability because of functional disomy of the corresponding genes. Female carriers are generally asymptomatic because of preferential inactivation of the abnormal X. In the present case, the 3.6-Mb-duplicated segment encompasses only 2 genes, DIAPH2 and RPL4A. Since the asymptomatic grandfather carries the duplication, we hypothesize that these genes are not dosage sensitive and/or involved in cognitive function. Our observation further illustrates that large copy number variants can be associated with a normal phenotype, especially where gene density is low. Reporting rare cases of large genomic imbalances without a phenotypic effect can be very helpful, especially for genetic counseling in the prenatal setting.
Acupressure for Managing Agitation in People with Dementia: Design of a Protocol Using the Delphi Technique
Authors: Kwan Rick Yiu Cho , Leung Mason Chin Pang , Lai Claudia Kam Yuk
Published: March 2017

Background: Preliminary studies support the effect of acupressure in managing agitation in people with dementia (PWD). However, procedures for the selection of intervention ingredients and specifications of the implementation techniques are lacking. This lack of information hinders further studies on the effect of acupressure and its subsequent clinical uses. The aim of this study was to develop an acupressure protocol and to identify its specifications. Methods: This study employed the Delphi technique, an approach to gain consensus on intervention ingredient selection to formulate the acupressure protocol through rounds of consultation among a panel of experts. Consensus of the protocol is considered when agreements on each ingredient reach and exceed 80%. Results: We invited 6 eligible traditional Chinese medicine (TCM) practitioners into the expert panel. An acupressure protocol with 100% agreement was developed in 3 rounds of consultation. Five acupoints and seven implementation specifications were identified. Conclusions: This study identifies the key intervention ingredients of acupressure and displays their procedures. The results support the notion that identification of acupressure ingredients for managing agitation in PWD by the Delphi technique is feasible. This study also identifies some intervention implementation specifications that have not been reported earlier, although the dosage (i.e. the frequency and duration) could not be well justified by the experts based on their clinical experience and the TCM theory. The study results suggest that further studies should focus on identifying the ideal dosage to be used and subsequently examine the effect of this standardized acupressure protocol as implemented by lay caregivers in randomized controlled trials.
Semiótica greimasiana na atribuição de autoria textual: contribuição à linguística forense
Authors: Almeida Dayane Celestino
Published: March 2017

Análises de autoria têm sido realizadas para responder a pergunta “Quem escreveu este texto?”, no curso de investigações criminais e processos judiciais. Assim, vários estudos sobre o tema, na área conhecida como linguística forense, começaram a surgir. Esses estudos baseiam-se na ideia de que cada autor tem um estilo. Porém, uma vez que em contextos forenses vários são os casos em que os textos arrolados para comparação são muito distintos entre si (isto é, de gêneros diferentes, destinados a interlocutores diferentes, etc.), há uma dificuldade em se distinguir autores, já que existe variação intrafalante (fenômeno amplamente demonstrado pela sociolinguística variacionista, e.g. Labov, 1966). Assim, este trabalho partiu da premissa de que, se os níveis mais profundos do percurso gerativo do sentido são mais abstratos e apresentam menos categorias de análise, eles seriam menos variáveis. A ideia é que quanto mais abstrato/simples o nível no plano do conteúdo, menos alternativas há para os indivíduos, o que leva a chances maiores de os autores sempre organizarem os textos segundo as mesmas categorias. Se com essa grande chance de realizar sucessivamente as mesmas escolhas, dois indivíduos distintos escolhem recorrentemente as mesmas opções, mas diferentemente um do outro, isso significa que a opção de cada um tem grande poder discriminatório. Portanto, o objetivo deste trabalho foi verificar se categorias de análise semiótica do plano do conteúdo poderiam ser utilizadas como marcadores de estilo em casos de atribuição forense de autoria textual. Textos de 4 autores foram analisados em um software que gera e armazena “etiquetas” posteriormente extraídas, o que possibilita a contagem de dados. Num segundo momento, semelhanças e diferenças entre os autores foram medidas estatisticamente utilizando dois coeficientes: Jaccard e Yule, empregados para medir o nível de similitude entre amostras. Os resultados indicam que a hipótese aventada se confirma.

O presente artigo tem por objetivo analisar, através de dispositivos das ciências linguísticas e da semiologia de orientação saussuriana, quatro composições do poeta austríaco Ernst Jandl (1925-2000), um dos precursores da poesia concreta e experimental no pós-Modernismo. Ricamente influenciado pelas vanguardas Modernas, como o dadaísmo e a poesia sonora, Jandl apresenta uma poesia capaz de nos conduzir a reflexões profundas sobre aspectos específicos das linguagens verbais em praticamente todos os seus níveis (isto é, fonológico, morfológico, semântico, sintático etc.), sobretudo da língua alemã, em que compôs suas obras. Deste modo, resta também como objetivo deste trabalho expandir os sentidos de leitura e o alcance destas reflexões a partir da reunião dos campos da linguística e da crítica literária, cuja reconciliação foi mais do que recomendada pelo linguista Roman Jakobson. Ao término de cada seção, uma tradução em língua portuguesa para cada poema estudado será proposta, valendo-se da adaptação, tanto lexical quanto métrica e prosódica, dos mesmos critérios que nortearam as análises aqui dispostas. Busca-se, por fim, com estas traduções, explicitar a aplicabilidade empírica das ferramentas da semiótica no estudo da poesia, bem como contribuir indiretamente com a tese da arbitrariedade do signo concebido através de uma perspectiva imanente, conforme proposta por Ferdinand de Saussure.

Structural and functional changes related to memory deficit in non-demential elderly individuals
Authors: Corrêa Nísea de A. , Foss Maria P. , Diniz Paula R. B.
Published: March 2017

Objective: Based on Magnetic Resonance Imaging (MRI), verify the structural and functional changes related to memory deficits in non-demented elderly individuals in comparison with young adults. Methodology: Proceeded a systematic review based on Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) fluxogram. The search was done on PubMed, Scopus and EBSCO databases using JabRef 2.10, and Web of Science. It was included in the analysis quasi-experimental, cross-sectional, cohort and case-control studies published between 2005 and 2014 in national and international indexed periodicals that had as sample: non-demented individuals older than 60 years old, who were submitted to MRI investigation of their for any brain structural and functional changes associated with memory deficits, identified in neuropsychologicals tests. Results: About the imaging technique, we reviewed studies that used structural MRIs (two articles), functional MRIs (six articles), both techniques (four articles). In the 12 studies, 38 distinct neuropsychological tests were used, an average of five different tests for each study (variation of 1-12). The most used tests were WAIS Digit Span Backwards (seven articles), Trail Making Test A and B (four articles) and Wechsler Memory Scale (four articles). Conclusion: The review showed that in normal aging the parahippocampal white substance, the hippocampus volume and entorhinal cortex slightly shrink, causing verbal memory reduction, possibly due to fiber demyelination; reduced connections between temporal and frontal lobes contributing to an impairement of episodic, working memory and verbal fluency; reduction suppression of irrelevant information, affecting the register of information; changes on frontal and parietal areas, compromising recognition memory; modifications in activity and connectivity of the default mode network; reorganization of cognitive functions and also a slower response, probably due to reduction of pre-frontal cortex activation
Methods and applicability of activity energy expenditure in the assessment of children: Review of the literature
Authors: Davoli Gabriela B. Q. , Figueiredo Marisa M. L. , Souza Mariana A. , Sverzut Ana Claudia M.
Published: March 2017

Study Design: Literature review. Children with chronic morbidities, progressive and / or functional disabilities are less active than healthy children. The metabolic changes that affect them favour increased energy expenditure (EE). The assessment of energy expenditure activity (EEA) provides specific details of the movement efficiency, and provides resources for establishing a therapeutic protocol.The gold standard for assessment of EEA by maximum oxygen uptake (VO2) is limited in a clinical routine by the complexity of data acquisition and its high charge value. Thus, predictive equations based on the linear relationship between heart rate (HR) and VO2 have been appointed as simple alternatives and easy to perform. However, there is no consensus about the best method to obtain the variables that compose these equations. Then, the aim of this study was to review the methods used to assess the EEA based on HR, pointing out the advantages and disadvantages in order to guide the clinical practice. In this review, 15 studies were analyzed considering (a) different types of route: tests performed on soil and mats; (b) speed: comfortable, self-selected and selected by the researchers; (c) predictive equations and variables analyzed: HR, time, distance traveled; (d) sample group: children with cerebral palsy, muscular dystrophy, cystic fibrosis and / or healthy. In general, the EEA, estimated by the energy expenditure index (EEI), was prevalent among these studies and its use has been reported as practical and reliable. Nevertheless, some methodological parameters could be improved in future studies

Published: March 2017

Design of the study: Case report. Objectives: To report a case of a patient with colorectal tumor prolapse located in the sigmoid. Methodology: A retrospective case report obtained from medical records. Results: We report a case of a patient awaiting surgery for tumor resection of a colorectal tumor, when she was sent to the service of medical emergencies with an episode of post-evacuation rectal prolapse with a tumor without spontaneous reduction. The patient was referred to emergency surgery and underwent a transabdominal approach, in which the prolapse was reduced then followed by Hartmann's rectosigmodectomy surgical procedure. Conclusions: Sigmoid tumor prolapse require a surgical approach, the approach of choice was abdominal retosigmoidectomy, following the oncological principles, with ligation of the inferior mesenteric artery at its origin. Relevance: Sigmoid tumor prolapse, a relatively unusual clinical situation in adults, and more rare complication when it comes to colorectal tumors, it must be treated immediately after diagnosis to reduce the risk of ischemia prolapsed segment, and whenever possible offer surgery to follow the precepts of cancer treatment. Comments: In the case reported, an emergency surgical approach was necessary, and the abdominal route was chosen following the principles of cancer surgery and shorter surgical time

Lugar, corporeidade e política: reflexões a partir do net-ativismo em redes sociais online
Authors: Xavier Marcos Antonio De Moraes
Published: March 2017

O net-ativismo realizado em redes sociais online inaugura novas formas e estratégias de ação política, mas não extingui ou diminui a importância das relações face a face. Nos últimos anos, a ocupação das ruas e espaços públicos por multidões em diferentes lugares do mundo tem sido uma amostra deste fato. Provavelmente, pelo fato de os problemas, indignações e solidariedades expressos nessas redes serem concretos nos lugares, onde efetivamente as pessoas vivem, e não em um espaço virtual metafórico.  No lugar: espaço banal, extensão de coexistência e vizinhança, as relações de reciprocidade são inescapáveis, pois, graças à nossa corporeidade, fazemos parte do campo prático da ação uns dos outros e, juntos, ainda que de forma desigual, enfrentamos nossos problemas. É nele, portanto, que a produção da consciência política é mais verossímil e que a ação de luta pode adquirir efetividade.
A certificação do latifúndio: considerações acerca do registro Torrens como blindagem da propriedade privada no caso das terras concentradas pelo Projeto Jari

Published: March 2017

O latifúndio constituído pelas terras do controverso Projeto Jari na divisa dos estados do Pará e do Amapá, na Amazônia brasileira, é composto pelo pretenso remembramento de mais de uma centena de imóveis. A legitimidade dessas terras é questionada em diversas e emaranhadas demandas judiciais. Pretende-se aqui dar um panorama da situação fundiária dessa área avaliando a apropriação ilegal de terras públicas, sobretudo por meio de registros Torrens, uma modalidade de registro imobiliário que garante uma blindagem especial à propriedade
Turismo, patrimônio cultural e produção do espaço: uma análise do centro histórico da cidade de Bragança-PA

Esta pesquisa analisa os desdobramentos das políticas e as ações de turismo e de preservação do patrimônio cultural que intervêm na produção do espaço do centro histórico da cidade de Bragança-PA e a participação dos agentes ligados ao turismo e ao patrimônio cultural no processo social e histórico na produção do espaço de seu centro histórico. Fizeram-se levantamentos e análises bibliográfica e documental e entrevistas semiestruturadas. O Estado é um agente que intervém no espaço com ações que visam a preservação. A população local também tem contribuído amplamente com a preservação do patrimônio cultural por meio de suas vivências num dos maiores expoentes do patrimônio bragantino, a Marujada de São Benedito. Quanto ao turismo, vários agentes atuam nesse espaço: a população local, os movimentos culturais e o Estado, um dos principais indutores do turismo, embora isso seja muito recente.
A produção do pensamento sobre a metrópole e o metropolitano pela escola de geografia urbana de São Paulo: o lugar de Sandra Lencioni
Authors: Leopoldo Eudes
Published: March 2017

A chamada escola de geografia brasileira pode ser considerada não como uma escola nacional clássica, mas como “uma escola com escolas”. Nesta perspectiva, compreende-se a constituição da escola de geografia urbana de São Paulo como uma das correntes mais importantes na escola de geografia brasileira, desenvolvida com base na produção de um pensamento sobre a cidade e o urbano, que se desloca para um pensamento sobre a metrópole e o metropolitano. Entre as expoentes, destaca-se uma síntese das contribuições científicas de Sandra Lencioni, especialmente sobre a teoria da região e a problemática metropolitana, e seus aportes à construção da escola de geografia urbana de São Paulo, à constituição da geografia brasileira e à produção do conhecimento geográfico universal.
A potencialidade das roupas na expressão política e na subjetivação de mulheres trans
Authors: Salgueiro Marques Angela Cristina , Mayrink Ana Luisa
Published: March 2017

Este artigo visa discutir parte de uma pesquisa realizada para compreender a relação entre a aparência de mulheres trans e seu respectivo potencial político. A partir dos conceitos de subjetivação, estética e política de Jacques Rancière, e da teoria de gênero proposta por Judith Butler, a pesquisa busca, através da realização de entrevistas semiestruturadas, descobrir como essas mulheres valem-se de recursos da ordem do visível para performar gênero e, ao mesmo tempo, dão a ver questões de sua exclusão sistemática dos espaços de discurso presentes na sociedade. O esforço empreendido foi no sentido de tentar entender como mulheres trans, particularmente as aqui entrevistadas, através da maquiagem, das roupas, do cuidado com os cabelos e de tantos outros artifícios que fazem parte da aparência visível, se apropriam criativamente de seus corpos, elaboram uma linguagem própria e inventam uma forma de vida cuja potência está no ato de aparecer, na construção de uma cena enunciativa argumentativa e performática animada pelo dissenso.

Investigo a noção de Índia espiritualizada baseada na ideia do discurso enquanto construção social.Analiso, por um lado, o discurso de peregrinos à Índia e, por outro, narrativas apresentadas em diversas fontes (páginas da Internet, jornais e revistas de turismo, livros, guias e agências de viagens) que promovem viagens à Índia.Entendo que a noção de uma Índia “espiritualizada” é frequentemente influenciada pelos discursos veiculados na mídia (e pelos próprios viajantes que relatam suas vivências aos familiares e amigos), devido ao fato de o “místico” e/ou “espiritual” ser o elemento que aparece ali e desse tipo de narrativa influenciar outros a estarem mais dispostos a enxergar certas situações como espirituais ou místicas. Verifiquei que esse tipo de narrativa é um indicativo da imagem construída pelos agentes sociais que têm por objetivo “divulgar a cultura indiana”.

Management of water resources may benefit from seasonal precipitation forecasts, but for obtaining high enough resolution, dynamical downscaling is necessary. This study investigated the downscaling capability of the Weather Research and Forecasting (WRF) Model ARW, version 3.5, on seasonal precipitation forecasts for the Hanjiang basin in China during 2001–09, which was the water source of the middle route of the South-to-North Water Diversion Project (SNWDP). The WRF Model is forced by the National Centers for Environmental Prediction Operational Climate Forecast System, version 2 (CFSv2), and it performs at a high horizontal resolution of 10 km with four selected convection schemes. The National Oceanic and Atmospheric Administration’s Climate Prediction Center global daily precipitation data were employed to evaluate the WRF Model on multiple scales. On average, when large biases were removed, the WRF Model slightly outperformed the CFSv2 in all seasons, especially summer. In particular, the Kain–Fritsch convective scheme performed best in summer, whereas little difference was found in winter. The WRF Model showed similar results in monthly precipitation, but no time-dependent characteristics were observed for all months. The spatial anomaly correlation coefficient showed greater uncertainty than the bias and the temporal correlation coefficient. In addition, the performance of the WRF Model showed considerable regional variations. The upper basin always showed better agreement with observations than did the middle and lower parts of the basin. A comparison of the forecast and observed daily precipitation revealed that the WRF Model can provide more accurate extreme precipitation information than the CFSv2.
Parental Knowledge of AAP Juice Guidelines Is Associated With Parent and Children’s Consumption of Juice and Sugar-Sweetened Beverages in an Underserved Population

Published: March 2017

This study tested whether parental knowledge of the American Academy of Pediatrics’ (AAP) recommendations on juice limits for children is associated with decreased consumption of juice and sugar-sweetened beverages (SSBs) among parents and children. Fifty-two parents with children 2 to 12 years old in a resident continuity clinic in East Harlem, New York, completed a survey asking about children’s and parent’s practice and quantitative consumption of juice and SSBs as well as parental knowledge of the AAP recommendations on juice limits. Parent’s total daily consumption of juice and SSBs ( P < .01), parent’s score on the test of AAP guidelines ( P = .04), and parent’s post–high school education ( P = .01) were associated with children’s juice and SSB consumption in a multivariable linear regression model. Children’s consumption of juice and SSBs is positively associated with parental consumption of juice and SSBs and negatively associated with parental formal education and knowledge of the AAP recommendations on juice limits.

This article, collaboratively written by the presidents of the National Latina/o Psychological Association (NLPA), presents leadership as conceptualized and practiced in NLPA. We first identify key leadership constructs in the available literature as well as relevant cultural values, describe liderazgo (leadership) through cultural lenses, and articulate the connections to counseling psychology and the social justice underpinnings that have guided NLPA’s formation and development. We then present a number of events and decisions to illustrate how we have operationalized these organizing principles in both the daily management and long-term goals of NLPA. We conclude with a discussion of the future paths and possible directions in the next decade for the organization.
Symbolic dynamics time series analysis for assessment of barely visible indentation damage in composite sandwich structures based on guided waves

Published: March 2017

This study addresses the detection and localization of barely visible indentation damage in composite sandwich structures using ultrasonic guided waves. A quasi-static loading was gradually applied on a specimen of carbon fiber reinforced epoxy with honeycomb core, with the resulting dent size varying between 0.2 and 2.7 mm. The fundamental symmetric (S0) Lamb wave mode was excited to interrogate the structure. An anomaly measure was established based on symbolic time series analysis; it was defined as the ratio between the norms of probability vectors obtained from the symbol sequence vectors before and after damage has occurred. The symbolic time series analysis method transforms time series data into symbol sequences according to a pre-constructed symbol space using a set number of partitions. The number of partitions selected was determined based on the maximum Shannon’s entropy approach. An imaging algorithm was adopted in order to localize the damage. The effects of the excitation frequency and the number of partitions on the precision of prediction were investigated. The adopted approach showed high sensitivity to a very small change of 0.2 mm on the surface panel after a quasi-static loading of 2-mm indentation. Furthermore, the ability of the method to detect progressive damage was demonstrated. The results obtained demonstrate that symbolic time series analysis has excellent potential for use in detecting small defects such as barely visible indentation damage.
DSM-5: Do Counselors Really Want an Alternative?
Authors: Gayle Michael C. , Raskin Jonathan D.
Published: March 2017

The results of a survey exploring counselor attitudes toward the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders ( DSM-5) are presented. The survey revealed that counselors have mixed attitudes toward the DSM. They view DSM positively and see it as both beneficial to their profession and important in determining treatment. They also believe that DSM-5 revisions reflect the best science available. Counselors worry that the DSM prioritizes diagnosis over treatment, have concerns about proposed DSM-5 revisions, and support developing alternatives to the DSM.
Engagement, Participation, and Situated Learning in a Children’s Opera Chorus Program
Authors: Dullea Rhoda
Published: March 2017

In recent years, opera companies throughout the United Kingdom have begun to provide educational programs for children that offer opportunities for “apprenticeship” training in the context of professional opera productions, alongside formal choral musicianship training. This article outlines a qualitative case study of a recently established children’s opera chorus program located in a northern England city, in which I investigated the extent to which the children became engaged with opera as a genre through their participation in the program. This study also considers the extent to which such programs affected children’s emerging cultural identities and musical preferences in an acculturative sense. Findings suggested that the authenticity and situatedness of the learning experience had a positive impact on the children’s engagement, with those that had participated in main-stage productions being most likely to state that they wished to pursue opera or musical theatre as a career in later life.
Imagining a Trans* Epistemology: What Liberation Thinks Like in Postsecondary Education
Authors: Nicolazzo Z
Published: March 2017

Postsecondary institutions of education, similar to the broader society in which they are embedded, are steeped in and further trans* oppression. In addition, the knowledge produced at these institutions is inflected with trans* oppression, and continues to reify the notion that trans* lives and experiences are abject, abnormal, unintelligible, and otherwise impossible. In this article, I build from the work of Patton, Brayboy, Delgado Bernal, and Spade to propose a trans* epistemology. In doing so, I discuss how this new epistemological stance helps educators unlearn the gender binary illogic in which they collude, thereby (re)shaping education as liberatory.
The Development and Initial Validation of the Citizen Disaster Communication Assessment
Authors: Spialek Matthew L. , Houston J. Brian
Published: March 2017

Current U.S. federal disaster management approaches advocate for citizens to engage in local efforts to cope with the negative consequences of disasters. In line with this approach, this project develops and validates the Citizen Disaster Communication Assessment (CDCA), which is a comprehensive survey instrument measuring individuals’ communication across disaster phases. The CDCA development process occurred over three studies. Study 1 consisted of assessment item generation and expert review. Study 2 determined the dimensionality of citizen disaster communication. Study 3 surveyed three communities experiencing different disaster phases in order to confirm the CDCA factor structure. Results (a) demonstrate evidence of an empirically derived citizen disaster communication measure and (b) inform current understanding of how citizens’ communication can participate in community disaster management. Future research should use the CDCA in other diverse communities to further validate the measure and to provide additional insight into the structural and sociodemographic factors influencing disaster communication.
‘Once upon a time in Bearland’: Longitudinal development of fictional narratives in South African children
Authors: Willenberg Ingrid
Published: March 2017

Children’s narrative skills have been widely studied in North America, but there is a paucity of African research. Within South Africa’s diverse socio-cultural context, this study of mixed-race children explored the development of narrative production and the influence of home background variables. Using the Bear Story picture prompt, this longitudinal study investigated the fictional oral narrative skills of 70 English-speaking children in kindergarten and Grade 3. Four key findings emerged: first, with age, narratives increased in lexical diversity, macrostructure elements and written discourse features. However, there was no increase in evaluation, thus highlighting the complexity and nonlinear nature of narrative development. Second, early book reading experiences in the home were positively associated with Grade 3 narrative macrostructure. Third, there were no associations between narrative abilities and maternal education or mothers speaking a first language other than English, underscoring the importance of parental behaviours above factors such as education and language background. Finally, contrary to expectations, the findings suggest more similarities than differences between these children and their peers in other contexts.

Published: March 2017

This study used a multiple probe (conditions) design across behaviors to investigate the effects of an app for the tablet computer to teach spelling of academic content words to four students with developmental disabilities. The app delivered instruction using a model-lead-test format and students typed on the on-screen keyboard. The study also evaluated the acquisition of nontarget information presented by the app in the form of identifying photos and definitions of the spelling words. The results indicated that all students learned their spelling words using the app and generalized the spelling to paper and pencil. They maintained most of their stimuli and learned the majority of the nontarget information to which they were exposed. Findings are discussed in the context of using technology-aided instruction and interventions that incorporate systematic instruction to teach academics and deliver nontarget information.
Inverse dynamics for actuator control of a transformable structure in space
Authors: Takatsuka Masao
Published: March 2017

This article proposes inverse dynamic calculation methods for actuator control of deployable structures and adaptive structures in space. The objective of this study is to estimate time change of an input moment controlled by an actuator which can gradually stop the transformation without acceleration and velocity at an assumed position and time so as not to cause structural vibration after the transformation. This article proposes three types of specific inverse calculation methods using trigonometric function and higher degree equations with their calculation examples which may be useful for design of an actuator considering deceleration control.
