Experimental Investigation of the Effect of Biodiesel Blends on a DI Diesel Engine’s Injection and Combustion
Authors: Tziourtzioumis Dimitrios , Stamatelos Anastassios
Published: July 2017

Differences in the evolution of combustion in a single cylinder, DI (direct injection) diesel engine fuelled by B20 were observed upon processing of the respective indicator diagrams. Aiming to further investigate the effects of biodiesel on the engine injection and combustion process, the injection characteristics of B0, B20, B40, B60, B80 and B100 were measured at low injection pressure and visualized at low and standard injection pressures. The fuel atomization characteristics were investigated in terms of mean droplet velocity, Sauter mean diameter, droplet velocity and diameter distributions by using a spray visualization system and Laser Doppler Velocimetry. The jet break-up characteristics are mainly influenced by the Weber number, which is lower for biodiesel, mainly due to its higher surface tension. Thus, Sauter mean diameter (SMD) of sprays with biodiesel blended-fuel is higher. Volume mean diameter (VMD) and arithmetic mean diameter (AMD) values also increase with blending ratio. Kinematic viscosity and surface tension become higher as the biodiesel blending ratio increases. The SMD, VMD and AMD of diesel and biodiesel blended fuels decreased with an increase in the axial distance from spray tip. Comparison of estimated fuel burning rates for 60,000 droplets’ samples points to a decrease in mean fuel burning rate for B20 and higher blends.
An Enhanced Empirical Wavelet Transform for Features Extraction from Wind Turbine Condition Monitoring Signals
Authors: Shi Pu , Yang Wenxian , Sheng Meiping , Wang Minqing
Published: July 2017

Feature extraction from nonlinear and non-stationary (NNS) wind turbine (WT) condition monitoring (CM) signals is challenging. Previously, much effort has been spent to develop advanced signal processing techniques for dealing with CM signals of this kind. The Empirical Wavelet Transform (EWT) is one of the achievements attributed to these efforts. The EWT takes advantage of Empirical Mode Decomposition (EMD) in dealing with NNS signals but is superior to the EMD in mode decomposition and robustness against noise. However, the conventional EWT meets difficulty in properly segmenting the frequency spectrum of the signal, especially when lacking pre-knowledge of the signal. The inappropriate segmentation of the signal spectrum will inevitably lower the accuracy of the EWT result and thus raise the difficulty of WT CM. To address this issue, an enhanced EWT is proposed in this paper by developing a feasible and efficient spectrum segmentation method. The effectiveness of the proposed method has been verified by using the bearing and gearbox CM data that are open to the public for the purpose of research. The experiment has shown that, after adopting the proposed method, it becomes much easier and more reliable to segment the frequency spectrum of the signal. Moreover, benefitting from the correct segmentation of the signal spectrum, the fault-related features of the CM signals are presented more explicitly in the time-frequency map of the enhanced EWT, despite the considerable noise contained in the signal and the shortage of pre-knowledge about the machine being investigated.
Effect of Wind Farm Noise on Local Residents’ Decision to Adopt Mitigation Measures
Authors: Botelho Anabela , Arezes Pedro , Bernardo Carlos , Dias Hernâni , Pinto Lígia
Published: July 2017

Wind turbines’ noise is frequently pointed out as the reason for local communities’ objection to the installation of wind farms. The literature suggests that local residents feel annoyed by such noise and that, in many instances, this is significant enough to make them adopt noise-abatement interventions on their homes. Aiming at characterizing the relationship between wind turbine noise, annoyance, and mitigating actions, we propose a novel conceptual framework. The proposed framework posits that actual sound pressure levels of wind turbines determine individual homes’ noise-abatement decisions; in addition, the framework analyzes the role that self-reported annoyance, and perception of noise levels, plays on the relationship between actual noise pressure levels and those decisions. The application of this framework to a particular case study shows that noise perception and annoyance constitutes a link between the two. Importantly, however, noise also directly affects people’s decision to adopt mitigating measures, independently of the reported annoyance.
Body Shape and Weight Loss as Motivators for Breastfeeding Initiation and Continuation
Authors: Schalla Sophie , Witcomb Gemma , Haycraft Emma
Published: July 2017

Breastfeeding rates in the UK are low. Efforts to promote breastfeeding typically include the known health benefits for mother and child, many of which are not immediate. Gaining immediate benefits can be effective motivators of behaviour. Body-related changes resulting from breastfeeding could be an immediate benefit. This study explored breastfeeding mothers’ reports of body-related changes as benefits of breastfeeding. Mothers (N = 182) who currently, or had recently, breastfed an infant completed a survey detailing their infant feeding choices and the perceived benefits of breastfeeding on their bodies. Half of the mothers felt that breastfeeding had a positive effect on their body. Benefits were grouped into five themes: (1) Returning to pre-pregnancy body shape; (2) Health benefits; (3) Physical benefits; (4) Eating benefits; (5) Psychological benefits. These themes highlight the numerous body-related benefits that mothers identified as resulting from breastfeeding and suggest that immediate, personal, and appearance-related gains of breastfeeding are highly valued. These findings indicate that interventions would likely benefit from emphasising the more immediate physical and psychological benefits of breastfeeding, alongside the health and bonding benefits, as a way to promote breastfeeding initiation and continuation in more women. This may be particularly effective for groups such as young mothers, where breastfeeding rates are low and whose emphasis on body image may be greater.

Authors: Toledo Diana , Soldevila Núria , Guayta-Escolies Rafel , Lozano Pau , Rius Pilar , Gascón Pilar , Domínguez Angela
Published: July 2017

Annual recommendations on influenza seasonal vaccination include community pharmacists, who have low vaccination coverage. The aim of this study was to investigate the relationship between influenza vaccination in community pharmacists and their knowledge of and attitudes to vaccination. An online cross-sectional survey of community pharmacists in Catalonia, Spain, was conducted between September and November 2014. Sociodemographic, professional and clinical variables, the history of influenza vaccination and knowledge of and attitudes to influenza and seasonal influenza vaccination were collected. The survey response rate was 7.33% (506 out of 6906); responses from 463 community pharmacists were included in the final analyses. Analyses were performed using multivariable logistic regression models and stepwise backward selection method for variable selection. The influenza vaccination coverage in season 2013–2014 was 25.1%. There was an association between vaccination and correct knowledge of the virus responsible for epidemics (adjusted Odds Ratio (aOR) = 1.74; 95% CI 1.03–2.95), recommending vaccination in the postpartum (aOR = 3.63; 95% CI 2.01–6.55) and concern about infecting their clients (aOR = 5.27; 95% CI 1.88–14.76). In conclusion, community pharmacists have a very low influenza vaccination coverage, are not very willing to recommend vaccination to all their customers but they are concerned about infecting their clients.
Evaluating Childhood Vaccination Coverage of NIP Vaccines: Coverage Survey versus Zhejiang Provincial Immunization Information System
Authors: Hu Yu , Chen Yaping
Published: July 2017

Vaccination coverage in Zhejiang province, east China, is evaluated through repeated coverage surveys. The Zhejiang provincial immunization information system (ZJIIS) was established in 2004 with links to all immunization clinics. ZJIIS has become an alternative to quickly assess the vaccination coverage. To assess the current completeness and accuracy on the vaccination coverage derived from ZJIIS, we compared the estimates from ZJIIS with the estimates from the most recent provincial coverage survey in 2014, which combined interview data with verified data from ZJIIS. Of the enrolled 2772 children in the 2014 provincial survey, the proportions of children with vaccination cards and registered in ZJIIS were 94.0% and 87.4%, respectively. Coverage estimates from ZJIIS were systematically higher than the corresponding estimates obtained through the survey, with a mean difference of 4.5%. Of the vaccination doses registered in ZJIIS, 16.7% differed from the date recorded in the corresponding vaccination cards. Under-registration in ZJIIS significantly influenced the coverage estimates derived from ZJIIS. Therefore, periodic coverage surveys currently provide more complete and reliable results than the estimates based on ZJIIS alone. However, further improvement of completeness and accuracy of ZJIIS will likely allow more reliable and timely estimates in future.

Published: July 2017

Pseudoxanthoma elasticum (PXE) is an autosomal recessive disorder characterized by the mineralization of connective tissues in the body. Primary manifestation of PXE occurs in the tissues of the skin, eyes, and cardiovascular system. PXE is primarily caused by mutations in the ABCC6 gene. The ABCC6 gene encodes the trans-membrane protein ABCC6, which is highly expressed in the kidneys and liver. PXE has high phenotypic variability, which may possibly be affected by several modifier genes. Disease advocacy organizations have had a pivotal role in bringing rare disease research to the forefront and in helping to sustain research funding for rare genetic diseases in order to help find a treatment for these diseases, pseudoxanthoma elasticum included. Because of these initiatives, individuals affected by these conditions benefit by being scientifically informed about their condition, having an effective support mechanism, and also by contributing to scientific research efforts and banking of biological samples. This rapid progress would not have been possible without the aid of disease advocacy organizations such as PXE International.
The Evaluation of the Reactivating and Neuroprotective Efficacy of Two Newly Prepared Bispyridinium Oximes (K305, K307) in Tabun-Poisoned Rats—A Comparison with Trimedoxime and the Oxime K203

Published: July 2017

The ability of two newly developed oximes (K305, K307) to protect tabun-poisoned rats from tabun-induced inhibition of brain acetylcholinesterase, acute neurotoxic signs and symptoms and brain damage was compared with that of the oxime K203 and trimedoxime. The reactivating and neuroprotective effects of the oximes studied combined with atropine on rats poisoned with tabun at a sublethal dose were evaluated. The reactivating efficacy of a newly developed oxime K305 is lower compared to the reactivating efficacy of the oxime K203 and trimedoxime while the ability of the oxime K307 to reactivate tabun-inhibited acetylcholinesterase (AChE) in the brain roughly corresponds to the reactivating efficacy of the oxime K203 and it is slightly lower compared to trimedoxime. In addition, only one newly developed oxime (K307) combined with atropine was able to markedly decrease tabun-induced neurotoxicity although it did not eliminate all tabun-induced acute neurotoxic signs and symptoms. These results correspond to the histopathological evaluation of tabun-induced brain damage. Therefore, the newly developed oximes are not suitable for the replacement of commonly used oximes (especially trimedoxime) in the treatment of acute tabun poisonings.

Published: July 2017

A series of new quinoxaline derivatives of dehydroabietic acid (DAA) were designed and synthesized as potential antitumor agents. Their structures were characterized by IR, 1H-NMR, 13C-NMR, and MS spectra and elemental analyses. All the new compounds were screened for their in vitro antiproliferative activities against three human cancer cell lines (MCF-7, SMMC-7721 and HeLa) and noncancerous human hepatocyte cells (LO2). A cytotoxic assay manifested that compound 4b showed the most potent cytotoxic activity against the three cancer cell lines, with IC50 values of 1.78 ± 0.36, 0.72 ± 0.09 and 1.08 ± 0.12 μM, respectively, and a substantially lower cytotoxicity to LO2 cells (IC50: 11.09 ± 0.57 μM). Moreover, the cell cycle analysis suggested that compound 4b caused cell cycle arrest of SMMC-7721 cells at the G0/G1 phase. In a Hoechst 33258 staining assay, compound 4b caused considerable morphological changes of the nuclei of SMMC-7721 cells, correlated with cell apoptosis. In addition, an Annexin V-FITC/PI dual staining assay confirmed that compound 4b could induce the apoptosis of SMMC-7721 cells in a dose-dependent manner.

Authors: Wyszynski Bartosz , Yatabe Rui , Nakao Atsuo , Nakatani Masaya , Oki Akio , Oka Hiroaki , Toko Kiyoshi
Published: July 2017

Mimicking the biological olfaction, large odor-sensor arrays can be used to acquire a broad range of chemical information, with a potentially high degree of redundancy, to allow for enhanced control over the sensitivity and selectivity of artificial olfaction systems. The arrays should consist of the largest possible number of individual sensing elements while being miniaturized. Chemosensitive resistors are one of the sensing platforms that have a potential to satisfy these two conditions. In this work we test viability of fabricating a 16-element chemosensitive resistor array for detection and recognition of volatile organic compounds (VOCs). The sensors were fabricated using blends of carbon black and gas chromatography (GC) stationary-phase materials preselected based on their sorption properties. Blends of the selected GC materials with carbon black particles were subsequently coated over chemosensitive resistor devices and the resulting sensors/arrays evaluated in exposure experiments against vapors of pyrrole, benzenal, nonanal, and 2-phenethylamine at 150, 300, 450, and 900 ppb. Responses of the fabricated 16-element array were stable and differed for each individual odorant sample, proving the blends of GC materials with carbon black particles can be effectively used for fabrication of large odor-sensing arrays based on chemosensitive resistors. The obtained results suggest that the proposed sensing devices could be effective in discriminating odor/vapor samples at the sub-ppm level.
Rehabilitation plus OnabotulinumtoxinA Improves Motor Function over OnabotulinumtoxinA Alone in Post-Stroke Upper Limb Spasticity: A Single-Blind, Randomized Trial
Authors: Devier Deidre , Harnar JoAnn , Lopez Leandro , Brashear Allison , Graham Glenn
Published: July 2017

Background: OnabotulinumtoxinA (BoNT-A) can temporarily decrease spasticity following stroke, but whether there is an associated improvement in upper limb function is less clear. This study measured the benefit of adding weekly rehabilitation to a background of BoNT-A treatments for chronic upper limb spasticity following stroke. Methods: This was a multi-center clinical trial. Thirty-one patients with post-stroke upper limb spasticity were treated with BoNT-A. They were then randomly assigned to 24 weeks of weekly upper limb rehabilitation or no rehabilitation. They were injected up to two times, and followed for 24 weeks. The primary outcome was change in the Fugl–Meyer upper extremity score, which measures motor function, sensation, range of motion, coordination, and speed. Results: The ‘rehab’ group significantly improved on the Fugl–Meyer upper extremity score (Visit 1 = 60, Visit 5 = 67) while the ‘no rehab’ group did not improve (Visit 1 = 59, Visit 5 = 59; p = 0.006). This improvement was largely driven by the upper extremity “movement” subscale, which showed that the ‘rehab’ group was improving (Visit 1 = 33, Visit 5 = 37) while the ‘no rehab’ group remained virtually unchanged (Visit 1 = 34, Visit 5 = 33; p = 0.034). Conclusions: Following injection of BoNT-A, adding a program of rehabilitation improved motor recovery compared to an injected group with no rehabilitation.
ON PRICE CO-MOVEMENT AND VOLATILITY SPILLOVER EFFECTS IN CHINA’S HOUSING MARKETS
Authors: WENG Yingliang , GONG Pu
Published: July 2017

The soaring property prices in many Chinese cities have recently attracted increasing attention. This study uses the data on housing price indices from January 2005 to December 2014 in 10 large Chinese cities to analyze volatility spillover effects and to identify the determinants of price co-movement across the China’s regional housing markets. This research proposes a novel dynamic spatial panel data model that accounts for multivariate asymmetrical generalized autoregressive conditional heteroskedasticity components in disturbances to address these issues empirically. Results reveal that housing prices in cities are significantly influenced by population, income, mortgage rates, policy factors, and the national macroeconomic situation. The analysis further indicates that the housing returns of regions in China that are in close geographic and economic proximities exhibit strong co-movement and volatility spillovers. Evidence of significantly positive leverage effects in regional housing markets is also determined. This study’s findings have significant implications for academic researchers, financial experts, and policy makers.
New Suns in the Cosmos. IV. The Multifractal Nature of Stellar Magnetic Activity in Kepler Cool Stars

Published: July 2017

In the present study, we investigate the multifractal nature of a long-cadence time series observed by the Kepler mission for a sample of 34 M dwarf stars and the Sun in its active phase. Using the Multifractal Detrending Moving Average algorithm, which enables the detection of multifractality in nonstationary time series, we define a set of multifractal indices based on the multifractal spectrum profile as a measure of the level of stellar magnetic activity. This set of indices is given by the (A,

, C, H)-quartet, where A,

, and C are related to geometric features from the multifractal spectrum and the global Hurst exponent H describes the global structure and memorability of time series dynamics. As a test, we measure these indices and compare them with a magnetic index defined as S
ph and verify the degree of correlation among them. First, we apply the Poincaré plot method and find a strong correlation between the

index and one of the descriptors that emerges from this method. As a result, we find that this index is strongly correlated with long-term features of the signal. From the multifractal perspective, the

index is also strongly linked to the geometric properties of the multifractal spectrum except for the H index. Furthermore, our results emphasize that the rotation period of stars is scaled by the H index, which is consistent with Skumanich’s relationship. Finally, our approach suggests that the H index may be related to the evolution of stellar angular momentum and a star’s magnetic properties.

On Automated Generation of Keyboard Layout to Reduce Finger-Travel Distance
Authors: Mali Amol D. , Yang Nan
Published: July 2017

The QWERTY keyboard layout can be very inefficient for one-finger typing on virtual keyboards since the letters in many common digrams are placed on opposite sides of the keyboard, resulting in a long finger travel. This paper reports on use of simulated annealing for finding alternate arrangements of the letters of the English alphabet on keyboards with different number of rows, to reduce finger-travel distance for entering text. The use of simulated annealing led to arrangements of the letters on 3 × 10, 4 × 7, and 5 × 6 layouts with a lower weighted sum of finger-travel distances for all digrams (denoted by d) compared to the QWERTY layout (lower by about 40%). The layout with the least value of d among those found in this work is a 5 × 6 layout for which the value of d is only 1.78 key widths compared to 3.31 key widths (the value of d for QWERTY). Alternate automated methods to solve this problem, connections between keyboard layouts and facility layouts, and many new applications of the ideas in this work are discussed.

A Meshfree Technique for Numerical Simulation of Reaction-Diffusion Systems in Developmental Biology
Authors: Jannesari Zahra , Tatari Mehdi
Published: July 2017

In this work, element free Galerkin (EFG) method is posed for solving nonlinear, reaction-diffusion systems which are often employed in mathematical modeling in developmental biology. A predicator-corrector scheme is applied, to avoid directly solving of coupled nonlinear systems. The EFG method employs the moving least squares (MLS) approximation to construct shape functions. This method uses only a set of nodal points and a geometrical description of the body to discretize the governing equation. No mesh in the classical sense is needed. However a background mesh is used for integration purpose. Numerical solutions for two cases of interest, the Schnakenberg model and the Gierer-Meinhardt model, in various regions is presented to demonstrate the effects of various domain geometries on the resulting biological patterns.

Authors: Ai Angela C , Maloney Francine L , Hickman Thu-Trang , Wilcox Allison R , Ramelson Harley , Wright Adam
Published: July 2017

Objective: To understand how clinicians utilize image uploading tools in a home grown electronic health records (EHR) system.

Methods: A content analysis of patient notes containing non-radiological images from the EHR was conducted. Images from 4,000 random notes from July 1, 2009 – June 30, 2010 were reviewed and manually coded. Codes were assigned to four properties of the image: (1) image type, (2) role of image uploader (e.g. MD, NP, PA, RN), (3) practice type (e.g. internal medicine, dermatology, ophthalmology), and (4) image subject.

Results: 3,815 images from image-containing notes stored in the EHR were reviewed and manually coded. Of those images, 32.8% were clinical and 66.2% were non-clinical. The most common types of the clinical images were photographs (38.0%), diagrams (19.1%), and scanned documents (14.4%). MDs uploaded 67.9% of clinical images, followed by RNs with 10.2%, and genetic counselors with 6.8%. Dermatology (34.9%), ophthalmology (16.1%), and general surgery (10.8%) uploaded the most clinical images. The content of clinical images referencing body parts varied, with 49.8% of those images focusing on the head and neck region, 15.3% focusing on the thorax, and 13.8% focusing on the lower extremities.

Conclusion: The diversity of image types, content, and uploaders within a home grown EHR system reflected the versatility and importance of the image uploading tool. Understanding how users utilize image uploading tools in a clinical setting highlights important considerations for designing better EHR tools and the importance of interoperability between EHR systems and other health technology.

Published: July 2017

El debate sobre la independencia de Cataluña se convirtió en el tema principal de las elecciones autonómicas catalanas del 27 de septiembre de 2015. Un año antes, el 9 de noviembre de 2014, se había celebrado una polémica consulta sobre idéntico asunto. En esta investigación se contrastaron las representaciones informativas de ambas convocatorias electorales realizadas por los principales periódicos de Madrid y Cataluña. Se efectuó un análisis de contenido de carácter cuantitativo para calcular estadísticos descriptivos e inferenciales, que mostraron la relevancia máxima concedida a este tema durante el tiempo que duró la campaña electoral. El debate sobre la independencia supuso más del 80% de las informaciones sobre la campaña electoral. Además se detectó la novedosa aparición de fuentes y protagonistas económicos e internacionales respecto a la consulta del año anterior. En cambio se mantuvo el enmarcado informativo antagónico entre los medios catalanes y madrileños.

En ese sentido, la temática sensacionalista es recurrente bajo variables como: ‘discriminación’, ‘racismo’, ‘élite’ y ‘tradición’. Para ello, el presente trabajo hace uso de la metodología del análisis cualitativo de contenido, así como la revisión bibliográfica y documental. Se concluye que el sensacionalismo es históricamente un recurso frecuente en los medios de información. Se recomienda la alfabetización en medios, a fin de no invisibilizar o vulnerar los derechos humanos de los colectivos sociales, como es el caso de las mujeres afrodescendientes de Colombia.

El propósito de este estudio es analizar las creencias, opiniones, experiencias y actitudes de las mujeres españolas en cursos de formación ocupacional respecto a la educación formal inicial, la formación ocupacional y permanente, con la intención de reflejar la concepción de la realidad social de la mujer en los ámbitos educativo y laboral. Para ello se ha aplicado una metodología cualitativa de entrevistas en profundidad, semiestructuradas, individuales y en grupo, a mujeres en cursos de formación ocupacional. También se han realizado entrevistas a personas expertas en igualdad de género. Los resultados indican que la socialización de género tiene un papel determinante en las elecciones académicas y laborales de las mujeres entrevistadas, cuyo desarrollo se ve condicionado por las responsabilidades familiares y de cuidado que tradicionalmente se han asignado a la mujer. Los factores familiares, económicos e individuales son los que más influyen en el abandono de la educación formal. La principal motivación para la formación permanente es el enriquecimiento personal, aunque una vez que se ha formado la familia, la mujer encuentra dificultad de conciliar la vida familiar y el desarrollo profesional. No obstante, las mujeres dejan entrever la posibilidad de un cambio que sería deseable por alcanzar la igualdad de género en los ámbitos de la formación y laboral. Previamente habría que estudiar las necesidades de las mujeres y los factores de éxito de la formación desde una perspectiva de género, considerando factores internos (motivaciones, intereses, etc.) y externos (contextos laboral, familiar, económico, etc.).
Efectos de la crisis económica sobre el emprendimiento en empresas de economía social en España: un análisis espacial

Published: July 2017

En los últimos años, la desfavorable evolución de la coyuntura económica ha provocado intensos cambios estructurales y espaciales en la creación de empresas que cuestionan la validez de algunos supuestos básicos sobre dinámica emprendedora y desarrollo territorial. Por ello, el objetivo de este trabajo es analizar la existencia de patrones espaciales de creación de empresas de economía social en España y estudiar su evolución temporal durante dos etapas de intensos cambios: una de crecimiento (2002-2007) y otra de profunda crisis generalizada (2008-2013). A partir de la definición de un índice de agrupación de empresas de economía social aplicamos técnicas estadísticas basadas en econometría espacial (índice de Moran y LISA). Para tal fin se tomaron datos longitudinales del número de empresas creadas en España, durante el período 2002-2013, bajo las fórmulas de economía social y mercantil comparándose posteriormente a nivel autonómico. Su dinámica se analiza conjuntamente con el PIB regional como indicador del contexto económico. Los resultados más generales apuntan a que el patrón de expansión de la dinámica emprendedora en empresas de economía social es negativo y regionalmente heterogéneo, mostrando la existencia de algunas concentraciones espaciales, en lo que podrían denominarse Clusters de Empresas de Economía Social. A la vista de esos resultados y patrones se evidencia una erosión en la influencia de determinados factores de tipo contextual (tradición, cultura y normativa) en esa actividad emprendedora. Nuestras contribuciones tienen implicaciones para la academia y para los decisores de políticas públicas de apoyo a la creación de empresas y la economía social.
Fatores associados ao fraco acesso das meninas ao Ensino Primário em Moçambique
Authors: Zimbico Octavio Jose
Published: July 2017

O fraco acesso das meninas à escola primária em Moçambique está no centro da questão deste texto, que tem como problema o fato de não se saber as razões por que, historicamente, as meninas têm estado em desvantagem numérica, na escola primária, comparativamente com os meninos. O objetivo é identificar e tipificar as possíveis fatores associados a este fenômeno desde o período anterior a 1975, ano em que o país alcançou a sua independência do domínio colonial português. Do ponto de vista metodológico, a revisão bibliográfica, o estudo da legislação, a análise dos dados estatísticos (primários e secundários) constituem a base de sustentação das ideias deste trabalho, de natureza histórica. A análise desse material revela que, por um lado, fatores socioculturais conjugados com os de natureza política têm estado na origem do fraco acesso das meninas à escola primária em Moçambique, desde a segunda metade do século XIX. Por outro, esses fatores e o modo de organização e funcionamento da sociedade moçambicana influenciam-se mutuamente.Factors associated with girls’ poor access to Primary Education in Mozambique. The poor access of girls to Primary Education in Mozambique is at the heart of this text, which has as the problem of not knowing the reasons why, historically, girls have been numerically disadvantaged in Primary Education, when compared to Boys. The aim is to identify and typify the possible factors associated with this phenomenon, from the period prior to 1975, the year in which the country reached its independence from Portuguese colonial rule. From the methodological point of view, the bibliographic review, the study of legislation, and the analysis of statistical data (primary and secondary) are the basis for sustaining the ideas of this historical work. The analysis of this material reveals that, on the one hand, social and cultural factors linked with those of a political nature have been the origin of the poor access of girls to primary school in Mozambique, since the second half of the nineteenth century. On the other hand, these factors and the way of organization and functioning of Mozambican society influence each other. Keywords: Gender; Girls; Access to Primary Education; History of Education in Mozambique.

Este artigo é uma tentativa de entender as relações sociais e de poder na construção de uma escola nos sertões do Rio Doce (Cuieté). Estudamos os processos de instituição do Estado na fronteira colonial, especialmente na gestão da força de trabalho dos povos indígenas. Problematizamos a construção de uma escola sobre os domínios indígenas, avaliando a configuração deste espaço, assim como os conflitos e identidades inerentes a este processo. O principal objetivo de nossos estudos é resgatar a historicidade dos povos conquistados em meio às representações e ações dos empreendimentos de conquista.Schools, catechesis and indigenous work in Minas Gerais (18th century). This article is an attempt to understand the social and power relationships in the construction of a school in the “sertões do Rio Doce” (Cuieté) ("hinterland of river Doce"). We studied the processes of institutionalization of the State in the colonial frontier, especially in the management of the indigenous workforce. We problematized the construction of a school in the indigenous domains, assessing the arrangement of this area, as well as conflicts and identities inherent to this process. The main purpose of this research is to retrieve the historicity of the colonized people amid the representations and actions of the ventures of conquest. Keywords: Indigenous school; Indigenous peoples; Brazil Colonial.
"Trata-se de uma rapariga de cor...": honestidade, moral e serviço doméstico feminino. Belo Horizonte, 1897-1920
Authors: Cassoli Marileide Lázara
Published: July 2017

Os diálogos entre a História da Educação e a História Cultural possibilitam desvelar aspectos diversos das práticas educacionais fora da escola e da escolarização, revitalizando, dessa forma, as abordagens em História da Educação. A partir dessa perspectiva, buscamos compreender as interfaces existentes entre as dinâmicas sociais, culturais, políticas e “educacionais”, que marcaram as vivências das mulheres afrodescendentes, que se dedicaram aos serviços domésticos, em Belo Horizonte, Minas Gerais, entre os anos de 1897 a 1920, no âmbito do processo de formação do mercado de trabalho livre no Brasil. As histórias das mulheres afrodescendentes permitem “esboçar” múltiplos retratos das liberdades por elas construídas naquele contexto. Contudo, para aquelas que se dedicaram ao serviço doméstico no pós-abolição, a conduta moral e o controle sobre o corpo feminino possibilitaram traçar um “fio condutor” em comum para as suas distintas histórias de vida e de trabalhadoras.“A girl of color…”: honesty, morality, and female domestic service. Belo Horizonte, 1897-1920. The dialogues that exist between the History of Education and Cultural History reveal various aspects of educational practices outside of school and schooling, thus revitalizing our approaches to the History of Education. Based on this perspective, we sought to understand the existing interfaces between the social, cultural, political, and "educational" dynamics that marked the experiences of Afro-descendant women who dedicated themselves to domestic services in Belo Horizonte, Minas Gerais, from 1897 to 1920, as part of the process of forming the free labor market in Brazil. The histories of Afro-descendant women allow us to "sketch" multiple portraits of the freedoms that they created within this context. However, for those who dedicated themselves to domestic services in the post-slavery era, moral conduct and control of the female body enabled us to trace a common thread running through the different histories of their lives and work. Keywords: Work; Education; Gender.
