À Sombra do Precursor: produção e recepção da obra <i>O Negro no Pará</i>, de Vicente Salles
Authors: Mafra Alessandra 
Published: November 2016

Este artigo objetiva analisar o contexto de produção e a recepção da clássica obra O Negro no Pará sob o regime da escravidão, lançada por Vicente Salles (1931-2013) em 1971, a partir da premissa de que a compreensão de um intelectual polígrafo como Salles pode ser interpretada através de momentos-chave, e não necessariamente lineares, de sua trajetória profissional, como sugere Pierre Bourdieu. Trajetória, esta, assentada nos estudos sobre o negro, o folclore e a música na Amazônia. Lançando mão da teoria de Stuart Hall sobre a recepção, as formas comunicativas e as práticas discursivas – sobretudo a relação entre o produtor-codificador e os receptores-decodificadores –, analisa-se um conjunto diversificado de fontes como as cartas trocadas por Vicente Salles com outros intelectuais paraenses, jornais e entrevistas realizadas com o intelectual ora examinado. Palavras-chave: O Negro no Pará; Vicente Salles; Intelectuais - Amazônia; Produção-Codificação; Recepção-Decodificação.
Ciência e hereditariedade na história de um assassino em série: em busca do gene perdido de Febronio
Authors: Carvalho Leonardo Dallacqua de , Souza Breno Sabino Leite de 
Published: November 2016

Este artigo pretende analisar a relação entre alcoolismo e hereditariedade a partir do estudo de caso do conhecido assassino em série da década de 1920, Febronio Indio do Brasil. Inicialmente, pretendemos mostrar o desenvolvimento da conduta criminal de Febronio no periódico Correio da Manhã e a construção da imagem de um indivíduo propenso à criminalidade. Tal questão nos levará à análise do Boletim Anti-alcoolico que, em circulação em 1929, explicaria a condição de Febronio por consequência do alcoolismo paterno, gestando um indivíduo propenso à criminalidade. Assim, características hereditárias foram apontadas como causadoras de seu desvio de conduta. Portanto, observaremos os discursos médicos e científicos da época na tentativa de explicar a hereditariedade de Febronio e suas motivações criminais, principalmente em vista de discurso de um campo mais amplo composto por médicos, antropólogos e cientistas que desenvolveram trabalhos na área de criminologia, um interesse recorrente no pensamento científico do período. Palavras-chave: BRASIL, Febronio Indio do; Alcoolismo e crime; Hereditariedade; Assassinos; Homicidas em série.

BackgroundHepatitis C virus (HCV) core protein, in addition to its structural role to form the nucleocapsid assembly, plays a critical role in HCV pathogenesis by interfering in several cellular processes, including microRNA and mRNA homeostasis. The C-terminal truncated HCV core protein (C124) is intrinsically unstructured in solution and is able to interact with unspecific nucleic acids, in the micromolar range, and to assemble into nucleocapsid-like particles (NLPs)in vitro. The specificity and propensity of C124 to the assembly and its implications on HCV pathogenesis are not well understood.MethodsSpectroscopic techniques, transmission electron microscopy and calorimetry were used to better understand the propensity of C124 to fold or to multimerize into NLPs when subjected to different conditions or in the presence of unspecific nucleic acids of equivalent size to cellular microRNAs.ResultsThe structural analysis indicated that C124 has low propensity to self-folding. On the other hand, for the first time, we show that C124, in the absence of nucleic acids, multimerizes into empty NLPs when subjected to a pH close to its isoelectric point (pH ≈ 12), indicating that assembly is mainly driven by charge neutralization. Isothermal calorimetry data showed that the assembly of NLPs promoted by nucleic acids is enthalpy driven. Additionally, data obtained from fluorescence correlation spectroscopy show that C124, in nanomolar range, was able to interact and to sequester a large number of short unspecific nucleic acids into NLPs.DiscussionTogether, our data showed that the charge neutralization is the major factor for the nucleocapsid-like particles assembly from C-terminal truncated HCV core protein. This finding suggests that HCV core protein may physically interact with unspecific cellular polyanions, which may correspond to microRNAs and mRNAs in a host cell infected by HCV, triggering their confinement into infectious particles.
Precision motion control of a small launching platform with disturbance compensation using neural networks
Authors: Hu Jian , Liu Lei , Wang Yuan‐gang , Xie Zhiwei 
Published: November 2016

SummaryA kind of launching platform driven by two permanent magnet synchronous motors which is used to launch kinetic load to hit the target always faces strong parameter uncertainties and strong external disturbance such as the air current impulsion which would degrade their tracking accuracy greatly. In this paper, a practical method which combines adaptive robust control with neural network‐based disturbance observer is proposed for high‐accuracy motion control of the launching platform. The proposed controller not only accounts for the parametric uncertainties but also takes the external disturbances into account. Adaptive control is designed to compensate the former, while neural network‐based disturbance observer is designed to compensate the latter respectively and both of them are integrated together via a feedforward cancellation technique. A new kind of parametric adaptation and weight adaptation strategy is designed by using the linear combination of the system's tracking error and the weight estimation error as a driving signal for parametric adaptation and disturbance approximation. The stability of the novel control scheme is analyzed via a Lyapunov method and this method presents a prescribed output tracking performance in the presence of both parameter uncertainties and unmodeled nonlinearities. Extensive comparative simulation and experimental results are obtained to verify the high‐performance of the proposed control strategy. Copyright © 2016 John Wiley & Sons, Ltd.

AbstractAmongst the most promising materials designed to catalyse water oxidation from earth‐abundant materials are the metal oxides. Despite the success of these materials, understanding the relationship of structure to function has been very challenging. It has been noted that many metal oxide water‐oxidation catalysts function best in a proton‐accepting electrolyte, such as a borate or phosphate buffer. However, these same electrolytes are known to significantly affect the metal oxide structures by imparting a level of “disorder” or “molecular nature” to the materials. The most well‐known case is that of Nocera's Co–Pi catalyst (Pi: inorganic phosphorus). In this study, we have synthesised a series of “heterogenite‐like” cobalt oxides with different levels of phosphate doping (0–9 %P). Our synthetic method enables us to make “bulk materials”, the structural properties of which (as observed by X‐ray absorption spectroscopy and transmission electron microscopy) mimic those observed directly on electrode surfaces. The changes made to the bulk phases were directly correlated with the reactivity for water‐oxidation catalysis and the ability of the CoOx materials to act as sacrificial oxidants. The most disordered materials were most reactive for sacrificial oxidation but were less effective as water‐oxidation catalysts. These results help us understand how disorder changes the thermodynamic stability of metal oxides and how this impacts on efficiency for water oxidation.
Reducing environmental uncertainty: How high performance work systems moderate the resource dependence‐firm performance relationship
Authors: Bendickson Josh , Gur Furkan A. , Taylor Erik C. 
Published: November 2016

AbstractFirm performance is a major concern for all organizations and involves a multitude of antecedents. Reducing environmental uncertainty and dependency through the use of strategic actions in the resource dependency theory (RDT) framework and enhancing work practices through high performance work systems (HPWS) lead to higher levels of firm performance. We reveal the interconnectivity between RDT and HPWS and develop propositions as to how components of HPWS positively moderate the relationship between firm performance and the environmental uncertainty‐reducing strategic actions proposed by RDT such as mergers and acquisitions, joint ventures, boards of directors, political action, and executive succession.

An anisotropic and inhomogeneous hidden Markov model for the classification of water quality spatio‐temporal series on a national scale: The case of Scotland
Authors: Spezia Luigi , Brewer Mark J. , Birkel Christian 
Published: November 2016

This work presents a case study about the evaluation of the water quality dynamics in each of the 56 major catchments in Scotland, for a period of 10 years. Data are obtained by monthly sampling of water contaminants, in order to monitor discharges from the land to the sea. We are interested in the multivariate time series of ammonia, nitrate, and phosphorus. The time series may present issues that make their analysis complex: non‐linearity, non‐normality, weak dependency, seasonality, and missing values. The goals of this work are the classification of the observations into a small set of homogeneous groups representing ordered categories of pollution, the detection of change‐points, and the modeling of data heterogeneity. These aims are pursued by developing a novel spatio‐temporal hidden Markov model, whose hierarchical structure was motivated by the data set to study: the observations are displayed on a cylindrical lattice and driven by an anisotropic and inhomogeneous hidden Markov random field. As a result, four hidden states were selected, showing that catchments could be grouped spatially, with a strong relationship with the dominating land use. This method represents a useful tool for water managers to have a nationwide picture in combination of temporal dynamics.
Numerical computation of a large‐scale jet fire of high‐pressure hydrogen in process plant
Authors: Jang Chang Bong , Jung Seungho 
Published: November 2016

AbstractDue to numerous hazardous chemicals to handle, the process plant industry has a higher risk of fire, explosion, and toxic release than other industries. Reviewing the accidents at process plants in the past, it is clear that fire accidents occur with the highest frequency, leading this study to consider accidental fire scenarios at process plants. For the scenario of an incident, a jet fire involving a massive amount of hydrogen gas to be processed or delivered at the process plant has been selected. The analysis of incident outcome resulting from the hydrogen jet fire has been implemented through the computational fluid dynamics simulation methodology Kameleon FireEx. Based on the outcome of this simulation, the consequences of a jet fire with high temperature and heat radiation are analyzed and evaluated. In addition, the results from Phast ver. 7.11 simulation for the same scenario are presented for comparison and further validation.

Published: November 2016

AbstractThe aim of the present study was to investigate the interplay between attention deficit hyperactivity disorder (ADHD) symptoms and emotional functioning in relation to peer problems. Parent ratings of ADHD symptoms and regulation/reactivity with regard to four emotions (anger, sadness, fear, and happiness/exuberance) at age six were investigated in relation to sociometric peer nominations 3 years later in a non‐clinical sample (n = 91). Reactivity and regulation were only modestly correlated, and these two aspects of emotional functioning did not show the same relation to peer problems. The main finding was that, it was primarily children with high levels of ADHD symptoms in combination with either high dysregulation or low reactivity with regard to happiness/exuberance who received many negative peer nominations. In addition, high levels of ADHD symptoms in combination with high reactivity with regard to anger were associated with nominations of physical aggression. The modest relation between reactivity and regulation emphasizes the importance of separating these two constructs. The fact that it was primarily happiness/exuberance, as opposed to negative emotions, that was associated with negative peer nominations suggests that future studies are needed to clarify the role of specific emotions in relation to the functional impairments associated with ADHD symptoms.Highlights

The present study aimed to investigate the interplay between ADHD symptoms and emotional functioning in relation to peer problems using a longitudinal design (age 6–9 years).
Ratings of ADHD symptoms and emotional functioning were investigated in relation to sociometric peer nominations and results showed that it was primarily children with high levels of ADHD symptoms in combination with either high dysregulation or low reactivity with regard to happiness/exuberance who received many negative peer nominations.
The fact that it was primarily happiness/exuberance, as opposed to negative emotions, that was associated with negative peer nominations suggests that future studies are needed to clarify the role of specific emotions in relation to the functional impairments associated with ADHD symptoms.

Published: November 2016

ObjectivesMicroscopic tympanoplasty has been the standard surgery for repairing perforated tympanic membranes since the 1950s, but endoscopic tympanoplasty has been increasingly practiced since the late 1990s. In this study, we compared the efficacies of endoscopic and microscopic tympanoplasty.Data SourcesPubMed, Embase, MEDLINE, and the Clinical Trial Register.Review MethodsWe conducted a systematic review and meta‐analysis following the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis statement. We included clinical studies that compared the efficacies of endoscopic and microscopic tympanoplasty. We assessed the risk of bias and calculated the pooled relative risk (RR) estimates with 95% confidence interval (CI).ResultsWe identified four studies (involving 266 patients in total) that met the inclusion criteria. The pooled tympanic membrane closure rates and hearing results of endoscopic and microscopic tympanoplasty were comparable (85.1% vs. 86.4%, respectively; RR: 0.98; 95% CI: 0.85 to 1.11; I2 = 0) (mean difference of improvements of air‐bone gaps: −2.73; 95% CI: −6.73 to 1.28; I2 = 80%). The pooled canalplasty rate of endoscopic tympanoplasty was significantly lower than that of microscopic tympanoplasty. Patients receiving endoscopic tympanoplasty had a more desirable cosmetic result than did those receiving microscopic tympanoplasty.ConclusionsOur up‐to‐date review evidences the comparable tympanic membrane closure rates and hearing results for endoscopic and microscopic tympanoplasty. Patients receiving endoscopic tympanoplasty have a lower canalplasty rate and more desirable cosmetic result than do those receiving microscopic tympanoplasty. Laryngoscope, 127:1890–1896, 2017
Defining the hidden evidence in autism research. Forty per cent of rigorously designed clinical trials remain unpublished ‐ a cross‐sectional analysis

Published: November 2016

AbstractAutism spectrum disorders (ASD) have a prevalence of up to 2.7% and show significant rates of comorbidities. Pharmacological treatment can be difficult. New treatment options are needed, several are currently under investigation. Publication bias presents a major problem in current clinical research. This study was designed to quantify publication bias in rigorously designed ASD research. The database at ClinicalTrials.gov was searched for all completed randomized controlled clinical trials investigating interventions in ASD and their results made public. If results could neither be retrieved through search of the database, nor of scientific databases nor by enquiries of the responsible parties or sponsors listed, a trial was defined as not published. The search delivered N = 30 (60%) trials were published, N = 20 (40%) remained unpublished, N = 2,421 (59%) patients were enrolled in the published trials, N = 1,664 (41%) patients in the unpublished trials, time to publication was 21.4 months [standard deviation (SD) = 18.48; range = −5 to 80 months]. Results of N = 22 trials were available through ClinicalTrials.gov. Characteristics of published compared to unpublished trials did not show apparent differences. The majority of trials investigated drugs. The results emphasize the serious issue of publication bias. The large proportion of unpublished results precludes valuable information and has the potential to distort evidence for treatment approaches in ASD.
A new statistical model for the Day Reconstruction Method
Authors: Lee Paul H. , Tse Andy C.Y. , Lee Ka Yiu 
Published: November 2016

AbstractThe Day Reconstruction Method (DRM) is a method to measure one's subjective affective status by soliciting information in a questionnaire about the previous day's activities. We developed a new model to examine the association of daily activities, the friendliness of interacting partners, and time‐of‐day on net affect scores among 10,377 adults participating in the World Health Organization's Study on global ageing and adult health (SAGE). A multilevel regression was fitted and the time‐of‐day effect was modeled by restricted cubic spline. The net affect score was a serpentine curve; stable from 4 a.m. to 6 a.m., increased from 7 a.m. to 12 noon, and became stable onwards. Participants had the highest net affect scores during religious activities (0.48, 95% confidence interval [CI]: 0.44, 0.53), and they enjoyed leisure activities, exercising, and household responsibilities more than work. Compared with events that lacked interacting partners, activities with very friendly interacting partners were associated with higher net affect scores (0.21, 95% CI: 0.19, 0.22), but events with slightly friendly interacting partners, slightly irritating or very irritating partners had lower net affect scores. To conclude, researchers using DRM for assessing well‐being status across time should include the type of activities and the friendliness of the interacting partners.

Published: November 2016

AbstractBACKGROUNDThe flower bug Orius sauteri (Poppius) (Hemiptera: Anthocoridae) is widely used as a biocontrol agent against thrips and aphids infesting greenhouse vegetables in Asia. The survival and oviposition of such predators, as well as the biocontrol services they provide, may be enhanced by adding extra floral resources to the crops. In the present study we investigated the effects of the plant Calendula officinalis L., used as a floral resource, for promoting the control of Myzus persicae (Sulzer) and Frankliniella occidentalis (Pergande) by O. sauteri under laboratory and greenhouse conditions.RESULTSResults showed that the presence of C. officinalis enhanced aphid and thrips suppression via an increased O. sauteri population growth. The predator populations responded positively to the addition of C. officinalis in the system, and they also varied as a function of the temperatures tested under laboratory conditions. In a similar way, predator populations varied among seasons, with the highest densities recorded in May in the greenhouse.CONCLUSIONC. officinalis can be used to increase available resources for natural enemies used in agricultural crops, notably in greenhouses. This study also provides evidence that increasing floral resources can enhance pest suppression provided by O. sauteri. © 2016 Society of Chemical Industry
