Bayesian reconstruction method for underwater 3D range-gated imaging enhancement
Authors: Yin Xiaojun , Cheng Hu , Yang Kecheng , Xia Min
Published: January 2020

We investigate a systematic improvement for 3D range-gated imaging in scattering environments. Drawbacks including absorption, ambient light, and scattering effect are studied. The former two are compensated through parameter estimation and preprocessing. With regard to the scattering effect, we propose a new 3D reconfiguration algorithm using a Bayesian approach that incorporates spatial constraints through a general Gaussian Markov random field. The model takes both scene depth and albedo into account, which provides a more informative and accurate restoration result. Hyper-parameters for the statistical mechanism are evaluated adaptively in the procedure and an iterated conditional mode optimization algorithm is employed to find an optimum solution. The performance of our method was assessed via conducting various experiments and the results also indicate that the proposed method is helpful for restoring the 2D image of a scene with improved visibility.
Robust single-photon counting imaging with spatially correlated and total variation constraints
Authors: Chen Wei , Li Song , Tian Xin
Published: January 2020

Single-photon counting imaging is a novel computational imaging technique that counts every photon collected by reflective light; it has target detection capability under extremely low-light conditions and thus has elicited increasing research interest. However, a low single-photon counting number and considerable noise will significantly affect image quality under low-light conditions. To improve the quality of single-photon counting image efficiently, we propose a robust single-photon counting imaging method with spatially correlated and total variation (TV) constraints. A robust Poisson negative log-likelihood function is introduced as a data fidelity term, which is robust to some spatial points that have extremely large background count in real situations. The TV regularization constraint is adopted to reduce noise. Considering that the reflectivity of several spatially correlated points may be similar, we suggest adding another constraint based on the counting information from these points rather than a single point for estimating reflectivity in each pixel. This approach will be helpful in reducing truncation errors. The proposed imaging model is formulated on the basis of the aforementioned factors. The alternative direction multiplier method is used to solve the optimization problem. The superiority of the proposed method over state-of-the-art techniques is verified on simulated and real captured experimental datasets under different conditions.

(RTP) crystal are combined in an intracavity-pumped Stokes parametric oscillator (SPO) to extend the tunable Stokes laser spectral range. The pumping laser wavelength is 1064 nm from a diode-end-pumped acousto-optically Q-switched Nd:YAG laser. By the SPS process in the SPO, the SPS-Stokes wave can be discontinuously tuned in the range of 1075.7–1076.0 nm, 1077.7–1080.4 nm, 1081.8–1082.2 nm, and 1084.8–1087.8 nm, respectively. By the following SRS process in the same RTP crystal, the laser wavelength is further shifted in the range of 1107.7–1108.1 nm, 1109.0–1112.7 nm, 1114.3–1115.1 nm, and 1117.8–1121.1 nm, respectively. A maximal average output power of 970 mW is achieved for the SRS-Stokes wave at the peak wavelength of 1118.8 nm. It is obtained when the diode power is 7.9 W, and the pulse repetition frequency (PRF) is 10 kHz.

Published: January 2020

Learning about language teacher cognition (LTC) is useful for understanding how language teachers act in the classroom. Employing an ecological framework, this study aimed to explore the factors influencing language teachers’ LTCs at different levels. To this end, qualitative data using semi-structured interviews and observation were collected from 62 (30 males and 32 females) Iranian EFL teachers. The results indicated that, at microsystem level, factors such as teaching equipment and facilities, teachers’ mood and feelings, their job satisfaction, and language proficiency influenced LTC. At mesosystem level, LTC was influenced by teachers’ prior learning experience, the collaboration and collegiality among teachers working in the language institute, teachers’ self-efficacy, and critical incidents that happened when teaching or learning. Additionally, the results indicated that exosystem level factors including teacher appraisal criteria, the teaching program and curriculum, and teacher immunity affected LTC. Moreover, LTC was subject to the influence of the government’s attitudes about ELT and religious beliefs about self and interaction, and friendliness with students at macrosystem level. More importantly, it was found that the factors influencing LTC were interrelated and interconnected and in several cases, LTC was a product of joint effect of several factors at various ecosystem levels. Finally, findings in this study suggest that language teaching programs provide recent educational technology in the classroom, foster collaboration and collegiality among teachers, and clarify teacher appraisal criteria for teachers in order to help create positive language teaching beliefs.

All around the world, patients with diabetes and the prevalence of its disease are currently growing. Due to these side effects of oral hypoglycemic agents and oxidative stress in complicating diabetes, there is growing interest in drugs, which possess dual function as both type II diabetes mellitus treatment and oxidative stress treatment. The objective of this research is to search effective antidiabetes and antioxidant bioactive compounds from the Myanmar medicinal plantClausena excavata. The root part ofC. excavatawas successfully extracted with 95% ethanol and followed by column chromatographic separation technique. The structure of isolated pure compounds was elucidated by using methods of spectroscopic such as UV-Vis, IR, NMR and HRFABMS spectrometry. The α-glucosidase inhibition assay was performed against baker’s yeast and rat intestine (sucrose and maltase) α-glucosidases. The activity of isolated compounds’ antioxidant was measured by using DPPH assay. Among the tested enzymes, the two isolated compounds, which were dentatin (1) and heptaphylline (2), exhibited highest inhibitory on maltase enzymes with IC50values 6.75 and 11.46 μM; as positive control, acarbose (IC50, 2.35 μM) was utilized. Moreover, scavenging activity was found to be present upon seeing the result of antioxidant activity investigation of (1) and (2) (IC50values 2.66 and 1.55 mM), where ascorbic acid (IC500.012 mM) was used as standard. Both compounds showed their antidiabetic and antioxidant activity with different fashion, especially exhibited strongest activity against on maltase α-glucosidase.

Authors: Feng Xuedong , Yi Jing , Luo Peng
Published: January 2020

With the purpose of studying the influence of NO/O2 on the NOx storage activity, a Pt-Ba-Ce/γ-Al2O3 catalyst was synthesized by an acid-aided sol-gel method. The physical and chemical properties of the catalyst were characterized by X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) methods. The results showed that the composition of the catalyst was well-crystallized and the crystalline size of CeO2 (111) was about 5.7 nm. The mechanism of NO and NO2 storage and NOx temperature programmed desorption (NO-TPD) experiments were investigated to evaluate the NOx storage capacity of the catalyst. Pt-Ba-Ce/γ-Al2O3 catalyst presented the supreme NOx storage performance at 350℃, and the maximum value reached to 668.8 μmol / gcat. Compared with O2-free condition, NO oxidation to NO2 by O2 had a beneficial effect on the storage performance of NOx. NO-TPD test results showed that the NOx species stored on the catalyst surface still kept relatively stable even below 350℃.

Published: January 2020

For an increasing implementation of the low-temperature transportation in oilfield, it is urgent priority initially to study the physical and chemical properties to provide the vital technical support for the low-temperature transport of the polymer flooding. In this paper, the rheological behavior of polymer-containing fluid produced from the Daqing polymer flood were first studied for an adaptation of transportation under the oil’s freezing point temperature. The experiments progressed with different temperature, shear rate, water content and polymer concentration which have great impacts on the viscosity of the fluids produced aiming to find the phase transportation point for the application of the low-temperature transportation. It was displayed that a significant discontinuity in the viscosity occurs at some range of water content. Before the phase transition point, presented in W/O (water-in-oil) emulsion, the viscosity was lifted with the increase of the water content while after the phase transition point, forming the O/W (oil-in-water) type emulsion, the viscosity was dropped with an increase of water content. The phase transition points strongly depend on the polymer concentration in the fluids Produced. It was demonstrated that the phase transition points of polymer-containing fluids were 65%, 70%, 50%, 50% and 50%, corresponding to the polymer concentrations of 315mg/L, 503mg/L, 708mg/L, 920mg/L and 1053mg/L, respectively. The characteristics are attributed to the viscous polymer. The fluidity of the fluid produced was decreased with the increase of polymer concentration.
Phenomenology and Experimental Psychology: On the Prospects and Limitations of Experimental Research for a Phenomenological Epistemology
Authors: Berghofer Philipp
Published: January 2020

Husserl’s transcendental phenomenology is first and foremost a science of the structures of consciousness. Since it is intended to yield eidetic, i. e., a priori insights, it is often assumed that transcendental phenomenology and the natural sciences are totally detached from each other such that phenomenological investigations cannot possibly benefit from empirical evidence. The aim of this paper is to show that a beneficial relationship is possible. To be more precise, I will show how Husserl’s a priori investigations on consciousness can be supplemented by research in experimental psychology in order to tackle fundamental questions in epistemology. Our result will be a phenomenological conception of experiential justification that is in accordance with and supported by empirical phenomena such as perceptual learning and the phenomenon of blindsight. Finally, I shall shed light on the systematic limits of empirical research.
Knowledge Sharing at the Overstrand Municipality in Western Cape Hermanus, South Africa
Authors: May Belinda Louise , Fombad Madeleine
Published: January 2020

Service delivery remains a challenge in post-apartheid South Africa, notwithstanding the proactive legislations that have been in place since the end of apartheid in 1994 to ensure that municipalities enhance the developmental path through service delivery. Given the increasing interest in prioritising knowledge sharing in municipalities, this article advocates for knowledge sharing as a tool to improve service delivery at South African municipalities. It investigates knowledge sharing at the Overstrand municipality in Cape Town, South Africa and adopts a qualitative approach, using convenient sampling and semi-structured interviews. South Africa is a multicultural country where municipalities are recovering from the inequalities and disparities of apartheid. The article identifies methods of knowledge sharing; establishes the barriers to effective knowledge sharing; and suggests ways in which knowledge sharing could be enhanced at the municipality. Data was collected from the different departments of the Overstrand municipality. The findings reveal that knowledge sharing continues to remain a challenge although participants understood and recognised its importance. A lack of trust, poor communication between senior and junior colleagues, a lack of incentives and recognition, fear of losing one’s job and the absence of a formal strategy, relevant information and communication technology make knowledge sharing challenging. The article recommends a formal knowledge management strategy; a knowledge sharing culture; the use of ICTs for knowledge management and the need for leaders to champion knowledge sharing in all the departments of the Overstrand municipality. Although there is emerging research on knowledge management in the public sector, there is a dearth of research on municipalities.
Mating Behavioral Function of Preoptic Galanin Neurons Is Shared between Fish with Alternative Male Reproductive Tactics and Tetrapods
Authors: Tripp Joel A. , Salas-Allende Isabella , Makowski Andrea , Bass Andrew H.
Published: January 2020

Understanding the contribution of neuropeptide-containing neurons to variation in social behavior remains critically important. Galanin has gained increased attention because of the demonstration that galanin neurons in the preoptic area (POA) promote mating and parental care in mammals. How widespread these mechanisms are among vertebrates essentially remains unexplored, especially among teleost fishes, which comprise nearly one-half of living vertebrate species. Teleosts with alternative reproductive tactics exhibit stereotyped patterns of social behavior that diverge widely between individuals within a sex. This includes midshipman that have two male morphs. Type I males mate using either acoustic courtship to attract females to enter a nest they guard or cuckoldry during which they steal fertilizations from a nest-holding male using a sneak or satellite spawning tactic, whereas type II males only cuckold. Using the neural activity marker phospho-S6, we show increased galanin neuron activation in courting type I males during mating that is not explained by their courtship vocalizations, parental care of eggs, or nest defense against cuckolders. This increase is not observed during mating in cuckolders of either morph or females (none of which show parental care). Together with their role in mating in male mammals, the results demonstrate an unexpectedly specific and deep-rooted, phylogenetically shared behavioral function for POA galanin neurons. The results also point to galanin-dependent circuitry as a potential substrate for the evolution of divergent phenotypes within one sex and provide new functional insights into how POA populations in teleosts compare to the POA and anterior hypothalamus of tetrapods.

SIGNIFICANCE STATEMENTStudies of neuropeptide regulation of vertebrate social behavior have mainly focused on the vasopressin-oxytocin family. Recently, galanin has received attention as a regulator of social behavior largely because of studies demonstrating that galanin neurons in the preoptic area (POA) promote mating and parental care in mammals. Species with alternative reproductive tactics (ARTs) exhibit robust, consistent differences in behavioral phenotypes between individuals within a sex. Taking advantage of this trait, we show POA galanin neurons are specifically active during mating in one of two male reproductive tactics, but not other mating-related behaviors in a fish with ARTs. The results demonstrate a deep, phylogenetically shared role for POA galanin neurons in reproductive-related social behaviors with implications for the evolution of ARTs.

Opisuju se memi s instagramske mrežne stranice Mudrolije sa Twittera, koji se dijele u dvije skupine.

Published: January 2020

O presente artigo estuda o discurso de William Bonner em tempos eleitorais, no intento de analisar a subjetividade (BENVENISTE, 1995a, 1995b), a cenografia e o ethos discursivo (MAINGUENEAU, 2004, 2008a, 2008b, 2008c) constituintes das entrevistas realizadas por esse jornalista aos candidatos à presidência da república em 2014. Como corpus, selecionamos recortes de três entrevistas realizadas pelo Jornal Nacional aos presidenciáveis. Os procedimentos metodológicos que guiam esse estudo são de abordagem qualitativa e método descritivo e bibliográfico. Busca-se analisar as marcas deixadas no discurso como parte intrínseca da imagem do enunciador do Jornal Nacional. O estudo da cenografia permite vislumbrar o ethos discursivo de alguém que se impõe como incontestável, conhecedor de todos os discursos e que, ancorado no gênero entrevista, se sente na obrigação de polemizar todos os enunciados alheios. Um indivíduo justiceiro é o que se pode depreender da imagem que Bonner lança de si no discurso.

O sampling como ação afrodiaspórica nas canções de Criolo e Emicida
Authors: Pitta Alexandre Carvalho
Published: January 2020

Este trabalho tem como objetivo estudar as articulações entre concepções da canção popular urbana e a obra musical dos rappers Criolo e Emicida. Para essa abordagem, discutiremos, partindo de amostras de letras de música, a bricolagem como processo que desenvolve uma forma diferenciada de canção, que, nos artistas, está ligada ao gênero musical que os consagrou: o rap. Traçando eixos comparativos entre a bricolagem e o sampling, método que está na base das canções de rap, buscamos compreender como essa dinâmica interfere nas interpretações sobre a canção popular brasileira. Atrelado esse processo de recorte e colagem, Criolo e Emicida se colocam no lugar de fala do afrobrasileiro, a partir de uma perspectiva afrodiaspórica, evidenciando, no âmbito da música brasileira, os efeitos de um projeto de modernização no país que trouxe o desenvolvimento às custas do aumento das desigualdades sociais, cujos choques tornam-se evidentes em suas obras.

Published: January 2020

The aim of the given preliminary study was to check whether any changes in fi ne motor behaviour exist in switching from single to double task (with cognition charge) in proprioceptive sensory graphomotor test conditions. Ten students (fi ve males and fi ve females), aged from 20 to 30 years old, took part in the experiment - precision of tracking of the models in both experimental test conditions: without and with cognitive task (counting numbers back). The variables for assessment were obtained with use of the digitalized proprioceptive diagnostics (Tous, 2008; Tous, J.M., Muiños, Tous, O., & Tous J, 2012) of Mira y Lopez laboratory (University of Barcelona) that transformed the measurements of drawn lines on a touch screen from pixels into millimetres. As results showed, in the proprioceptive test condition, the changes in deviations related to spatial (lineograms) or line length variability (parallels) did not reach any statistical signifi cance; while the changes in line length performance (lineograms) were found signifi cant (that corresponds to inhibition- -excitatory balance of nervous system).

Published: January 2020

This article addresses teacher perception regarding how excessive amounts of extracurricular activities could interfere with regular lessons and, ultimately, affect student academic performance. A survey probing personal opinions regarding this phenomenon was completed by thirty teachers from public and private primary schools and high schools in the Costa Rican province of Puntarenas. The main objective of this study was not only to determine teacher perception, but also to compare collected data with already existing theory on this subject. Results show that even though some of those activities are relevant in training students to become good citizens and future professionals, an overload of extracurricular activities will negatively impact their achievements and knowledge acquisition.

El análisis del fenómeno de la deserción estudiantil en contextos universitarios resulta complejo por la interacción de múltiples factores sociales, familiares, individuales e institucionales. El propósito del estudio fue describir algunas variables sociodemográficas y motivacionales asociadas a la deserción de estudiantes de primer ingreso de programas de grado en las cohortes del 2011, 2012 y 2013, con estudiantes activos y desertores de una institución de educación superior estatal de Costa Rica. Para tal fin, se construyó un instrumento de preguntas cerradas y abiertas, el cual se validó con el juicio de expertos y un grupo focal. Posteriormente, con la técnica de la encuesta se aplicó el instrumento por vía WEB y telefónica a una muestra no probabilística de 519 estudiantes. Entre los resultados de la prueba chi-cuadrada se encontró que la condición de abandono se asoció con: no matricular la carrera que más deseaba, el poco interés por estudiar en la carrera en la cual fue admitido y el deseo de estudiar en otra institución. El principal hallazgo del estudio es que las variables motivacionales son las que más inciden en el abandono. A partir de estos resultados se recomienda una apropiada inducción vocacional, para reducir las probabilidades de deserción, así como generar una estrategia para mantener la motivación durante los dos primeros años de ingreso a la universidad.

Authors: Garro-Rojas Lidieth
Published: January 2020

Se analiza la literatura académica producida en Latinoamérica referida a las experiencias de alfabetización mediática con el fin de examinar la importancia del establecimiento de iniciativas de alfabetización mediática en esta región. Se desarrolla una amplia revisión bibliográfica y entre los hallazgos se encuentra que las principales discusiones en el subcontinente giran en torno a iniciativas de alfabetización mediática orientadas a la comprensión de contenidos y lenguajes, seguido del uso de herramientas tecnológicas y posteriormente el análisis de las condiciones institucionales en las cuales se desarrolla, o no, la alfabetización mediática. En la mayoría de los países latinoamericanos el surgimiento del campo de la alfabetización mediática se da más como resultado de las iniciativas de organizaciones y de algunas personas académicas interesadas en el tema, quienes generan reflexión sobre estas experiencias como producto de una agenda académica o de política educativa de interés para las autoridades educativas.

Toplumsal Dayanışma Ağlarının Gazetecilikte Kullanımı: Sosyal Sermayenin Kamusal Habercilikteki Rolünün İncelenmesi
Authors: BİÇER Ahmet , KOÇER Mustafa
Published: January 2020

Sosyal sermaye, bireysel ve toplumsal olmak üzere iki farklı gerçeklik düzleminde
değerlendirilebilir. Bireysel düzlemde sosyal sermaye; aktörlerin sosyal ilişkilerinden elde
ettikleri ve amaçları doğrultusunda kullandıkları bir kaynaktır. Toplumsal düzlemde ise; yaşanılan
bölgedeki komşuluk ilişkilerinden yardımlaşma düşüncesine, sivil toplum kuruluşlarından
dernekleşme faaliyetlerine kadar, bir dizi sivil katılım biçiminin toplumsal hayata sağladığı
katkıları ifade eden bir kaynak olarak değerlendirilmektedir. Dolayısıyla çalışmada, sosyal
yapılardan veya ilişkilerden elde edilen bir kaynak olan sosyal sermayeyi, gazetecilerin mesleki
pratiklerinde kullanmaları gerektiği varsayılmıştır. Bu varsayımdan hareketle, gazetecilerin
kamusal habercilik olanaklarında sosyal sermayenin rolünün incelenmesi amaçlanmıştır.
Çalışma amaçları doğrultusunda sosyal sermaye kavramsal olarak açıklanmış, gazetecilik alanıyla
sosyal sermaye yaklaşımının arasındaki ilişkileri konu alan literatüre kısaca yer verilmiştir. Saha
araştırmasında, gazetecilerin sosyal sermayeleri ve kamusal habercilik olanakları arasındaki ilişki
incelenmiş, gazetecilerin sosyal çevreleriyle yakınlıkları ve etkileşimleri açısından sosyal sermaye
ve kamusal habercilik olanaklarında oluşan farklılaşmalar araştırılmıştır. Ağırlıklı olarak İstanbul,
Ankara ve İzmir’de çalışan gazeteciler olmak üzere, toplam 384 gazeteciyle anket çalışması
gerçekleştirilmiştir. Elde edilen bulgular, araştırmaya katılan gazetecilerin sosyal sermayelerinin,
algıladıkları kamusal habercilik olanakları üzerinde istatistiksel olarak anlamlı ve pozitif yönlü
bir etkisinin bulunduğunu ortaya koymuştur. Ayrıca gazetecilerin sosyal çevreleriyle yakınlıkları
ve etkileşim sayıları arttıkça, sosyal sermaye ve kamusal habercilik olanakları ortalamalarının
arttığını gösteren bulgular tespit edilmiştir. Bu bağlamda sosyal sermayenin kamusal habercilik
pratiklerinde önemli bir rolü bulunduğu, toplumsal dayanışma ve iletişim ağlarına katılımın
toplum yanlısı gazetecilik pratiklerini kolaylaştırdığı anlaşılmıştır.
Katharsis Bir Duygu Olarak Şiddetin Marka Tutumuna Yansıması
Authors: DÖNMEZ Mevlüt Sedat
Published: January 2020

Bireylerin tutum ve davranışlarında etkili olduğu düşünülen insan duyguları temelde
mutluluk, üzüntü, korku, şaşırma, öfke ve tiksinme olarak sınıflandırılmaktadır. Bunun
yanı sıra tüketicilerin tercih ve tutumlarını etkileyen şiddet, endişe gibi hisler katharsis
duygular olarak değerlendirilmektedir. Bireylerin bedensel ve ruhsal arınması olarak
tanımlanan katharsis durum reklam içeriklerinde de kullanılarak tüketicilerde bir
rahatlama hissi oluşturmaktadır. Markalar ise hem temel duyguları hem de katharsis
duyguları reklam çekicilikleri çerçevesinde değerlendirerek tüketicilerde bir tutum ve
satın alma niyeti oluşturma çabası içerisine girmektedir. Bu noktada reklam uygulamaları
içerisinde en sık kullanılan katharsis duygulardan biri ise şiddet olarak görülmektedir. Bu
çerçevede katharsis şiddet duygusu bazı durumlarda tek başına bazı durumlarda ise diğer
duygularla birlikte tüketicilerde bir marka tutumu oluşturma amacıyla reklam çekiciliği
olarak kullanılmaktadır. Bu araştırma kapsamında katharsis bir duygu olan şiddetin
reklamda kullanımının markaya yönelik tutuma yansımasını tutumun bilişsel, duygusal ve
davranışsal alt boyutları açısından yaş, cinsiyet, eğitim durumu ve tanımlayıcı değişkenler
bağlamında irdelemek amaçlanmıştır. Bu amaçla araştırma bağlamında katharsis şiddeti
reklam içerikleri içerisinde kullanan Regal markası tercih edilmiş ve markaya yönelik
tutumu ölçmek hedeflenmiştir. Bu doğrultuda kolayda örneklem yöntemiyle 391 kişiyle
çevrimiçi anket tekniği uygulanarak veri toplanmıştır. Araştırma kapsamında cinsiyet
değişkeni ve tanımlayıcı değişkenler bağlamında tüketicilerin marka tutum alt boyutları
arasında farklılıklar olduğu görülürken, yaş ve eğitim durumu değişkenleri açısından
katılımcıların marka tutumu alt boyutlarında farklılıkların olmadığı sonucuna erişilmiştir.
Bu çerçevede kadınların erkeklere göre markaya daha zayıf bir tutum sergiledikleri
izlenmiştir. Ayrıca hem cinsiyet hem de tanımlayıcı değişkenler açısından tutumun bilişsel
ve duygusal alt boyutu bağlamında farklılıkların olduğu görülürken; tutumun davranışsal
alt boyutu açısından farklılıklar gözlenmemiştir.

The Alaska Volcano Observatory (AVO) seismic network has been in operation since 1988 and during this time has grown from 29 to 217 seismic stations providing real-time monitoring of 32 active volcanoes in Alaska, as well as useful data for regional earthquake monitoring. Since 1988, AVO has detected 59 volcanic eruptions at Aleutian arc volcanoes, and 31 of these have been captured by local seismic instrumentation. As part of this monitoring effort, AVO has cataloged more than 120,000 earthquake hypocenters and magnitudes associated with volcanic processes throughout the arc. This high rate of volcanic activity provides an excellent opportunity to study seismicity associated with magmatic and eruptive processes and develop and refine analytical techniques to track volcanic seismicity and warn of hazardous eruptions. The network is currently undergoing an extensive upgrade, replacing aging short-period analog seismometers with digital broadband instruments. These are expected to improve AVO’s seismic capability and further facilitate other geophysical instrumentation such as continuous Global Positioning System receivers, infrasound sensors, and web cams.
As escolas de ensino primário em Lisboa e no interior de Portugal, no limiar da descentralização oitocentista
Authors: Adâo Áurea
Published: January 2020

O Regulamento de 20 de dezembro de 1850 reforçou o papel da administração local, determinando que na criação de novas escolas teriam preferência os concelhos e as freguesias que dispusessem de casa própria e mobiliário adequado. Tal decisão foi completada anos mais tarde (1866) com a promulgação de um conjunto de normas sobre os espaços escolares e os seus equipamentos. O Município de Lisboa não gozou de privilégios especiais relativamente à instrução pública, devendo reger-se pelas normas gerais promulgadas para todo o país. E, tal como as outras municipalidades, também a de Lisboa não dispunha de meios financeiros suficientes, ainda que no seu território funcionasse a maior parte dos serviços administrativos centrais e as instituições políticas. Neste artigo é analisada a situação do ensino primário em dois territórios distintos: o Município de Lisboa, capital do Reino, eminentemente de características urbanas e o Município de Proença-a-Nova, com predominância de atividades rurais e poucos meios de comunicação, situado no interior do país. Para o estudo foram privilegiados, como fontes primárias, os questionários preenchidos durante uma Inspeção Extraordinária às Escolas Primárias, realizada em 1875. Foram também utilizados outros documentos oficiais e estudos da época.

Published: January 2020

O presente artigo procura sintetizar um conjunto de ideias que têm sido desenvolvidas por diversos autores, em torno do surgimento da higiene escolar e das políticas educativo-sanitárias em Portugal. Tomando o período da 1ª Republica como referência, este artigo procura esclarecer a realidade que potenciou o nascimento do movimento higienista, bem como a sua apropriação por parte do discurso republicano. Pretende-se ainda perceber qual o papel assumido pelo poder municipal no contexto de partilha de responsabilidades no campo educativo, tomando como exemplo a ação da Câmara Municipal do Porto no período compreendido entre 1910 e 1926.
