Published: January 2020

Esta investigación tiene como objetivo el diseño de una metodología de diagnóstico de fallos para contribuir al mejoramiento de los indicadores de eficiencia, mantenimiento y disponibilidad de los Sistemas Fotovoltaicos de Conexión a Red (SFVCR). Para lograr dicho objetivo, se realiza el estudio del inversor de conexión a red y del modelo matemático del generador fotovoltaico. Luego se cuantifican las pérdidas operacionales del generador fotovoltaico y se adapta el modelo matemático de éste a las condiciones reales del sistema a través de un ajuste polinomial. Un sistema real de conexión a red de potencia nominal 7.5 kWp, instalado en el Centro de Investigaciones de Energía Solar (CIES) en la provincia Santiago de Cuba, se utiliza para evaluar la metodología propuesta. Con los resultados obtenidos se valida el diseño propuesto para demostrar que éste supervisa con éxito el SFVCR. La metodología fue capaz de detectar e identificar el 100 % de los fallos simulados y los ensayos realizados tuvieron como máximo una tasa de falsa alarma de 0.22 %, evidenciándose su utilidad.

Published: January 2020

Introduction

This study was performed to explore the function of B-Raf proto-oncogene-activated non-coding RNA (BANCR) in laryngeal squamous cell carcinoma (LSCC) and cisplatin resistance.

Material and methods

The relative expression level of long non-coding RNA (lncRNA) BANCR was examined by qRT-PCR in tumor tissues and adjacent tissues, normal laryngeal cells (Het-1A) and laryngeal squamous carcinoma cells (TU686, TU177). Cisplatin-resistant laryngeal squamous carcinoma cell lines (TU686-DDP-R, TU177-DDP-R) were established. Next, we inhibited BANCR expression by transfecting siRNA-BANCR and enhanced BANCR expression by transfecting pcDNA3.1-BANCR into TU686, TU177, TU686-DDP-R and TU177-DDP-R cells. The CCK-8 assay and clone formation assay were performed to detect colony proliferation ability and formation ability of cells. Further, to investigate through which BANCR cell viability/formation is regulated, we detected the expression of MRP1, Bcl-2, p-PKB, and Bax by western blot.

Results

BANCR was highly expressed in laryngeal squamous carcinoma tissues and cells. Chemoresistance was generated in TU686-DDP-R and
TU177-DDP-R compared with TU686 and TU177 cells after cisplatin treatment. In addition, upregulated lncRNA BANCR reduced or postponed cell sensitivity to cisplatin by enhancing cell proliferation in TU686 and TU177 cells. Meanwhile, the expression of MRP1, Bcl-2, and p-PKB was increased, while Bax was reduced. After cisplatin treatment, down-regulation of BANCR could consequently attenuate TU686-DDP-R and TU177-DDP-R cell proliferation, and the expression of MRP1, Bcl-2, and p-PKB was decreased and Bax was increased.

Conclusions

Down-regulation of BANCR reverses cisplatin resistance of cisplatin-resistant LSCC cell lines.

Published: January 2020

Background

The aim of this study was to examine the psychometric properties of the Polish version of the Short Hopeless-ness Scale in an undergraduate student sample. The scale was originally developed as a brief measure of hopelessness for large scale epidemiological surveys and is based on two commonly used measures of hope-lessness.

Participants and procedure

A total of 4098 students from different Polish universities took part in the study. Confirmatory factor analysis (CFA) was used to test the model fit. Pearson correlation coefficients were used to investigate the relationship between hopelessness scale and criterion variables.

Results

Due to the lack of fit of the initial congeneric, unidimensional model, the lowest loading item was removed, and a tau-equivalent model with three items was tested. The tau-equivalent model showed a good fit to the data. The scale had adequate reliability. Hopelessness was positively related to anxiety, depression, and stress and negatively related to the quality of life, health, and self-esteem.

Conclusions

The study provides evidence of good psychometric properties in terms of factorial structure, reliability and crite-rion validity of the shortened 3-item Polish version of a hopelessness scale. Future studies should investigate its predictive value, especially in terms of suicidal ideation and behaviour, as well as other health outcomes.

Published: January 2020

Rheumatoid neutrophilic dermatitis is a rare extra-articular manifestation of rheumatoid arthritis, both seropositive and seronegative for rheumatoid factor. The condition most often presents as symmetric erythematous papules, nodules, plaques, and urticaria-like lesions in patients with severe, long-lasting rheumatoid arthritis. We report a case of a 65-year-old man with well-controlled rheumatoid arthritis, who developed rheumatoid neutrophilic dermatitis on the right lower leg. The biopsy of skin lesions revealed an intense, neutrophilic dermal infiltrate, microabscesses, and leukocytoclasis without vasculitis. The patient responded well to pulses of intravenous methylprednisolone. We present this patient due to the rarity of the disease and atypical unilateral manifestation involving the flexural surfaces of the lower leg.
Hand-arm vibration syndrome
Authors: Nieradko-Iwanicka Barbara
Published: January 2020

Use of vibrating tools often leads to development of hand-arm vibration syndrome. It manifests with vascular symptoms, neurologic (carpal tunnel syndrome) and musculoskeletal symptoms (impaired grip strength, osteoarthritis, bone necrosis). Kienböck’s disease is osteonecrosis of the lunate. A 61-year-old construction worker was referred to a rheumatologist because of suspected arthritis. On examination tenderness and swelling of the dorsal aspect of the right wrist were recorded without features of inflammation. The patient reported paresthesia in the right hand when working with a pneumatic drill. He reported no morning stiffness or Raynaud’s phenomenon. He had undergone surgery because of right carpal tunnel syndrome two years earlier. Rheumatoid factor was negative, CRP 0.2 mg/l, uric acid 4.7 mg/dl. In magnetic resonance avascular necrosis of the lunate was diagnosed and scaphoid fracture. Kienböck’s disease was diagnosed. Non-steroidal anti-inflammatory drugs were used. The patient did not give consent for surgery.

Published: January 2020

Objectives

Tumor growth factor b (TGF-b) is a pleiotropic cytokine which controls autoimmune reactions, cell proliferation, and the organ accumulation of lymphocytes. This cytokine has a protective and anti-inflammatory effect in autoimmune processes, but also has a pro-fibrinous activity. Therefore, its importance in the development of systemic sclerosis has been proven. The role of TGF-b in Sjögren’s syndrome is also a valid direction of research. The aim of the presented study is to evaluate the level of TGF-b in sera of primary Sjögren’s syndrome patients and to investigate possible correlations with autoantibodies, cytokines, and cells in biopsy of minor salivary glands active in the pathogenesis of this syndrome.

Material and methods

Thirty-three primary Sjögren’s syndrome patients were included. Routine laboratory tests and immunological assessment (ANA, anti SS-A, anti SS-B antibodies, rheumatoid factor), ophthalmological assessment with ocular staining scoring, chest X-ray, and high-resolution computed tomography (if necessary) were performed. Serum concentrations of cytokines such as TGF-b, BAFF, APRIL, FLT-3L, LT-a, IL-21, and TNF-a were evaluated using standard ELISA assays. The histopathological evaluation (focus score) and the determination of CD3+, CD4+, CD19+, CD21+, CD35+ cells was performed.

Results

There was no significant correlation between TGF-b and other tested cytokines or autoantibodies, other than TNF-a. A negative correlation (r = –0.472) between TGF-b and TNF-a was found. There were no correlations between TGF-b and: results of ocular examinations, elements of histopathological variables, or lungs changes.

Conclusions

The authors state that: 1) the results may indicate that TGF-b influences the serum TNF-a activity in pSS patients, 2) our findings suggest that TGF-b may be the strongest inhibitor of TNF-a among cytokines involved in pSS pathogenesis, and 3) the results may explain the ineffectiveness of anti-TNF drugs in the treatment of pSS.
Surface temperature response to the major volcanic eruptions in multiple reanalysis data sets
Authors: Fujiwara Masatomo , Martineau Patrick , Wright Jonathon S.
Published: January 2020

Abstract. The global response of air temperature at 2 m above
the surface to the eruptions of Mount Agung in March 1963, El Chichón in
April 1982, and Mount Pinatubo in June 1991 is investigated using 11 global
atmospheric reanalysis data sets (JRA-55, JRA-25, MERRA-2, MERRA,
ERA-Interim, ERA-40, CFSR, NCEP-NCAR R-1, 20CR version 2c, ERA-20C, and
CERA-20C). Multiple linear regression (MLR) is applied to the monthly mean
time series of temperature for two periods – 1980–2010 (for 10 reanalyses) and 1958–2001 (for 6 reanalyses) – by considering explanatory factors of
seasonal harmonics, linear trends, quasi-biennial oscillation (QBO), solar
cycle, tropical sea surface temperature (SST) variations in the Pacific,
Indian, and Atlantic Oceans, and Arctic SST variations. Empirical orthogonal
function (EOF) analysis is applied to these climatic indices to obtain a set
of orthogonal indices to be used for the MLR. The residuals of the MLR are
used to define the volcanic signals for the three eruptions separately.
First, area-averaged time series of the residuals are investigated and
compared with the results from previous studies. Then, the geographical
distribution of the response during the peak cooling period after each
eruption is investigated. In general, different reanalyses show similar
geographical patterns of the response, but with the largest differences in
the polar regions. The Pinatubo response shows the largest average cooling in
the 60∘ N–60∘ S region among the three eruptions, with
a peak cooling of 0.10–0.15 K. The El Chichón response shows slightly
larger cooling in the NH than in the Southern Hemisphere (SH), while the
Agung response shows larger cooling in the SH. These hemispheric differences
are consistent with the distribution of stratospheric aerosol optical depth
after these eruptions; however, the peak cooling after these two eruptions
is comparable in magnitude to unexplained cooling events in other periods
without volcanic influence. Other methods in which the MLR model is used
with different sets of indices are also tested, and it is found that careful
treatment of tropical SST variability is necessary to evaluate the surface
response to volcanic eruptions in observations and reanalyses.
Analysis of 24 years of mesopause region OH rotational temperature observations at Davis, Antarctica – Part 1: Long-term trends

Published: January 2020

Abstract. The long term trend, solar cycle response and residual variability in 24 years of hydroxyl nightglow rotational temperatures above Davis Research Station, Antarctica (68° S, 78° E) is reported. Hydroxyl rotational temperatures are a layer-weighted proxy for kinetic temperatures near 87 km altitude and have been used for many decades to monitor trends in the mesopause region in response to increasing greenhouse gas emissions. Routine observations of the OH(6–2) band P-branch emission lines using a scanning spectrometer at Davis station have been made continuously over each winter season since 1995. Significant outcomes of this most recent analysis update are (a) a record low winter-average temperature of 198.3 K is obtained for 2018 (1.7 K below previous low in 2009) (b) a long term cooling trend of 1.2 K/decade persists, coupled with a solar cycle response of 4.3 K/100 solar flux units and (c) we find evidence in the residual winter mean temperatures of an oscillation on a quasi-quadrennial (QQO) timescale which is investigated in detail in part 2 of this work. Our observations and trend analyses are compared with satellite measurements from Aura/MLS version v4.2 level 2 data over the last 14 years and we find close agreement (a best fit) with the 0.00464 hPa pressure level values. The solar cycle response, long-term trend and underlying QQO residuals are consistent with the Davis observations. Consequently, we extend the Aura/MLS trend analysis to provide a global view of solar response and long term trend for southern and northern hemisphere winter season to compare with other observers and models.

Abstract. On August 25, 2018 the interplanetary counterpart of the August 20, 2018 Coronal Mass Ejection (CME) hit the Earth, giving rise to a strong G3 geomagnetic storm. We present a description of the whole sequence of events from the Sun to the ground as well as a detailed analysis of the observed effects on the Earth's environment by using a multi instrumental approach. We studied the ICME propagation in the interplanetary space up to the analysis of its effects in the magnetosphere, ionosphere and at ground. To accomplish this task, we used ground and space collected data, including data from CSES (China Seismo Electric Satellite), launched on February 11, 2018. We found a direct connection between the ICME impact point onto the magnetopause and the pattern of the Earth's polar electrojects. Using the Tsyganenko TS04 model prevision, we were able to correctly identify the principal magnetospheric current system activating during the different phases of the geomagnetic storm. Moreover, we analyzed the space-weather effects associated with the August 25, 2018 solar event in terms of evaluation geomagnetically induced currents (GIC) and identification of possible GPS loss of lock. We found that, despite the strong geomagnetic storm, no loss of lock has been detected. On the contrary, the GIC hazard was found to be potentially more dangerous than other past, more powerful solar events, such as the St. Patrick geomagnetic storm, especially at latitudes higher than 60° in the European sector.
Reconstruction of Holocene oceanographic conditions in the Northeastern Baffin Bay

Published: January 2020

Abstract. The Baffin Bay is a semi-enclosed basin connecting the Arctic Ocean and the western North Atlantic, thus making out a significant pathway for heat exchange. Here we reconstruct the alternating advection of relatively warmer and saline Atlantic waters versus the incursion of colder Arctic water masses entering the Baffin Bay through the multiple gateways in the Canadian Arctic Archipelago and the Nares Strait during the Holocene. We carried out benthic foraminiferal assemblage analyses, X-Ray Fluorescence scanning and radiocarbon dating of a 738  cm long marine sediment core retrieved from the eastern Baffin Bay near Upernavik (Core AMD14-204C; 987m water depth). Results reveal that the eastern Baffin Bay was subjected to several oceanographic changes during the last 9.2 ka BP. Waning deglacial conditions with enhanced meltwater influxes and an extensive sea-ice cover prevailed in the eastern Baffin Bay from 9.2–7.9 ka BP. A transition towards bottom water ameliorations are recorded at 7.9 ka BP by increased advection of Atlantic water masses, encompassing the Holocene Thermal Maximum. A cold period with growing sea-ice cover at 6.7 ka BP interrupts the overall warm subsurface water conditions, promoted by a weaker northward flow of Atlantic waters. The onset of the Neoglaciation at ca. 2.9 ka BP, is marked by an abrupt transition towards a benthic fauna dominated by agglutinated species likely partly explained by a reduction of the influx of Atlantic water, allowing increased influx of the cold, corrosive Baffin Bay Deep Water originating from the Arctic Ocean, to enter the Baffin Bay through the Nares Strait. These cold subsurface water conditions persisted throughout the late Holocene, only interrupted by short-lived warmings superimposed on this cooling trend.
An online emission module for atmospheric chemistry transport
models: Implementation in COSMO-GHG v5.6a and COSMO-ART

Published: January 2020

Abstract. Emission inventories serve as crucial input for atmospheric chemistry transport models. To make them usable for a model simulation, they have to be pre-processed and, traditionally, provided as input files at discrete model time steps. In this paper, we present an online approach, which produces a minimal number of input data read in at the beginning of a simulation and which handles essential processing steps online during the simulation. For this purpose, a stand-alone Python package emiproc was developed, which projects the inventory data to the model grid and generates temporal and vertical scaling profiles for individual emission categories. The package is also able to produce offline emission files if desired. Furthermore, we outline the concept of the online emission module (written in Fortran 90) and demonstrate its implementation in two different atmospheric transport models, COSMO-GHG and COSMO-ART. Simulation results from both modeling systems show the equivalence of the online and offline procedure. While the model run-time is very similar for both approaches, disk storage and pre-processing time are greatly reduced when online emissions are utilized.
Use of dual-polarization weather radar quantitative precipitation estimation for climatology
Authors: Voormansik Tanel , Cremonini Roberto , Post Piia , Moisseev Dmitri
Published: January 2020

Abstract. Accurate, timely and reliable precipitation observations are mandatory for hydrological forecast and early warning systems. In the case of convective precipitations, traditional rain gauges networks often miss precipitation maxima, due to density limitations and high spatial variability of rainfall field. Despite several limitations like attenuation or partial beam-blockings, the use of C-band weather radar has become operational in most of European weather services. Traditionally, weather radar-based quantitative precipitation estimation (QPE) are derived by horizontal reflectivity data. Nevertheless, dual-polarization weather radar can overcome a number of shortcomings of the legacy horizontal reflectivity based estimation. For the first time, the present study analyses one of the longest datasets from fully operational polarimetric C-band weather radars; those ones are located in Estonia and in Italy, in very different climate conditions and environments. The study focuses on long-term observations of summertime precipitation and their quantitative estimations by polarimetric observations. From such derived QPEs accumulations for 1 hour, 24 hours and one month durations are calculated and compared with reference rain gauges to quantify uncertainties and evaluate performances.

Abstract. The role of precipitation (P) variability on evapotranspiration (ET) and its two components transpiration (T) and evaporation (E) rates from savannas continues to draw significant research interest given its relevance to a number of eco-hydrological applications. The work here reports on six years of measured ET and energy flux components, and estimated T from a grazed savanna grassland collected at a research site situated in Welgegund, South Africa. During this period, annual P varied considerably in amount (421 mm to 614 mm), rainy season length and precipitation intensity. T was estimated using annual water use efficiency and gross primary production determined from eddy-covariance measurements of net ecosystem CO2 exchange rates. The computed annual T was highly constrained to 352 ± 8 mm (T/ET = 0.55) for four wet years when rainfall was near or above the long-term mean. This is explained by the near constant annual tree transpiration and moderate water stress of C4 grasses during these years. In a drought year with intermittent rainfall, the annual ecosystem T was reduced due to grass dieback-regrowth that alters the temporal dynamics of bare soil cover and infiltration, and complicates monthly T/ET relation to leaf-area index (LAI). However, annual ET remains approximately equal to annual precipitation (P) even during the drought year due to increased soil evaporation. Indeed, at annual scales, ET ≈ P and annual T is conservative despite variation in amount and timing in rainfall, due to constant water use of mature trees, and the ability of C4 grasses to maintain transpiration at moderate water stress and effectively use pulsed rainfall.
A novel approach for the assessment of morphological evolution based on observed water levels in tide-dominated estuaries
Authors: Cai Huayang , Zhang Ping , Garel Erwan , Matte Pascal , Hu Shuai , Liu Feng , Yang Qingshu
Published: January 2020

Abstract. Assessing the impacts of both natural (e.g., tidal forcing from the ocean) and human-induced changes (e.g., dredging for navigation, land reclamation) on estuarine morphology is particularly important for the protection and management of the estuarine environment. In this study, a novel analytical approach is proposed for the assessment of estuarine morphological evolution in terms of tidally averaged depth on the basis of the observed water levels along the estuary. The key lies in deriving a relationship between wave celerity and tidal damping or amplification. For given observed water levels at two gauging stations, it is possible to have a first estimation of both wave celerity (distance divided by tidal travelling time) and tidal damping or amplification rate (tidal range difference divided by distance), which can then be used to predict the morphological changes via an inverse analytical model for tidal hydrodynamics. The proposed method is applied to the Lingdingyang Bay of the Pearl River Estuary, located on the southern coast of China, to analyse the historical development of the tidal hydrodynamics and morphological evolution. The analytical results show surprisingly good correspondence with observed water depth and volume in this system. The merit of the proposed method is that it provides a simple approach for understanding the decadal evolution of the estuarine morphology through the use of observed water levels, which are usually available and can be easily measured.
Bromine speciation and partitioning in slab-derived fluids and melts: Implications for halogens recycling in subduction zones
Authors: Louvel Marion , Sanchez-Valle Carmen , Malfait Wim J. , Pokrovski Gleb S. , Borca Camelia N. , Grolimund Daniel
Published: January 2020

Abstract. Understanding the behavior of halogens (Cl, Br, and I) in subduction zones is critical to constrain the recycling of trace elements and metals, and to quantify the halogen fluxes to the atmosphere via volcanic degassing. Here, the partitioning of bromine between coexisting aqueous fluids and hydrous granitic melts and its speciation in slab-derived fluids have been investigated in situ up to 840 °C and 2.2 GPa by X-ray fluorescence (SXRF) and absorption (XANES and EXAFS) spectroscopy in hydrothermal diamond-anvil cells. The partition coefficients Df/mBr range from 15.3 ± 1.0 to 2.0 ± 0.1, indicating the preferential uptake of Br by aqueous fluids at all investigated conditions. EXAFS analysis further evidences a gradual evolution of Br speciation from hydrated Br ions [Br(H2O)6]− in slab dehydration fluids to more complex structures invoving both Na ions and water molecules, [BrNax(H2O)y], in hydrous silicate melts and supercritical fluids released at greather depth (> 200 km). In dense fluids containing 60 wt % dissolved alkali-silicates and in hydrous Na2Si2O5 melts (10 wt % H2O), Br is found in a salt-like structure involving 6 nearest Na ions and several next-nearest O neighbors that are either from water molecules or the tetrahedral silicate network. Bromine (and likely chlorine and iodine) complexation with alkalis is thus an efficient mechanism for the mobilization and transport of halogens by hydrous silicate melts and supercritical fluids, which can carry high amounts of Br, up to the 1000 ppm level. Overall, our results suggest that both shallow dehydration fluids and deeper silicate-bearing fluids efficiently remove halogens from the slab in the sub-arc region, thus controling an efficient recycling of halogens in subduction zones.
New gravity-derived bathymetry for the Thwaites, Crosson and Dotson ice shelves revealing two ice shelf populations

Published: January 2020

Abstract. Ice shelves play a critical role in the long-term stability of ice sheets through their buttressing effect. The underlying bathymetry and cavity thickness are key inputs for modelling future ice sheet evolution. However, direct observation of sub-ice shelf bathymetry is time consuming, logistically risky, and in some areas simply not possible. Here we use airborne gravity anomaly data to provide new estimates of sub-ice shelf bathymetry outboard of the rapidly changing West Antarctic Thwaites Glacier, and beneath the adjacent Dotson and Crosson Ice Shelves. This region is of especial interest as the low-lying inland reverse slope of the Thwaites glacier system makes it vulnerable to marine ice sheet instability, with rapid grounding-line retreat observed since 1993 suggesting this process may be underway. Our results confirm a major marine channel > 800 m deep extends to the front of Thwaites Glacier, while the adjacent ice shelves are underlain by more complex bathymetry. Comparison of our new bathymetry with ice shelf draft reveals that ice shelves formed since 1993 comprise a distinct population where the draft conforms closely to the underlying bathymetry, unlike the older ice shelves which show a more uniform depth of the ice base. This indicates that despite rapid basal melting in some areas, these “new” ice shelves are not yet in equilibrium with the underlying ocean system. We propose qualitative models of how this transient ice-shelf configuration may have developed.
Las disparidades entre las cargas de dependencia demográficas provinciales. Argentina (1914-2040)
Authors: Manzano Fernando Ariel
Published: January 2020

Se parte de la explicación de las tendencias poblacionales caracterizada en la teoría de la transición demográfica que establece un patrón de cambios en natalidad y mortalidad que conlleva inevitablemente en todas las sociedades a una ventana temporal con mínima carga de dependencia demográfica. A partir del análisis de los datos censales a nivel provincial en Argentina durante el periodo 1914-2040, se visibilizan situaciones en las cuales la carga de dependencia demográfica se caracteriza por marcadas divergencias interprovinciales. Existen provincias que inician el periodo bajo estudio con baja carga de dependencia demográfica, y se mantienen en estas posiciones a lo largo del tiempo, mientras que en otras se desvanecen las ventajas relativas iniciales, en cambio las restantes provincias sobrellevan continuamente los efectos de este desequilibrio demográfico. La hipótesis es que la ausencia del componente migratorio es la limitación principal para explicar estas supuestas irregularidades por parte la teoría demográfica. Se presenta la relación entre los valores de la relación de dependencia demográfica provinciales y los flujos migratorios según años censales.

Published: January 2020

Este trabalho apresenta uma reflexão sobre a história da produção dos queijos (manteiga e creme) do Marajó/PA, Brasil. A pesquisa, de caráter qualitativo, utilizou como ferramentas e metodologias: entrevista semiestruturada e história oral temática. Buscou-se realizar resgate histórico da produção dos queijos; analisar as formas de transmissão do conhecimento e do modo de produção; e iniciar debate sobre as dificuldades enfrentadas para a preservação dessas práticas frente às exigências da regularização sanitária dos órgãos fiscalizadores. Como resultado, observou-se a importância socioeconômica, histórica, social e cultural da produção local de queijo para as famílias envolvidas; a adaptação da produção como forma de resistência e manutenção da artesanalidade da produção; o envelhecimento dos profissionais do queijo marajoara e a diminuição do número de pessoas interessadas em desenvolver a atividade. Esta pesquisa aponta para o grau de fragilidade desse modo de produção e a necessidade de elaboração de políticas públicas que incentivem, preservem e fomentem o conhecimento tradicional e a produção artesanal dos queijos do Marajó.

O mapa no ensino de geografia: uma análise do trabalho docente em Madrid (Espanha) e em Goiânia (Brasil)
Authors: Richter Denis , De la Vega Alfonso García
Published: January 2020

Este texto apresenta resultados de um estágio de pós-doutorado que teve como objetivo analisar como os professores de Geografia da Educação Infantil até o Ensino Superior de Madrid (Espanha) e de Goiânia (Brasil) trabalham com o mapa, enquanto linguagem cartográfica, em suas aulas na perspectiva de contribuir para a educação geográfica. Para isso foram realizadas entrevistas a um grupo de professores em exercício que atuam em distintos níveis escolares. Como resultado, observou-se que o mapa nas aulas de Geografia desses docentes tem sido valorizado, porém mais na perspectiva do pensamento espacial para os professores espanhóis, enquanto que os docentes brasileiros relacionam o mapa nas leituras e práticas do cotidiano. Contudo, como a formação inicial desses professores esteve vinculada fortemente à Cartografia numa perspectiva euclidiana, o trabalho com o mapa se revelou mais associado ao ensino dos conteúdos cartográficos. Espera-se com este estudo identificar proximidades e diferenças entre as práticas desses professores e que as análises provenientes possam orientar melhor o trabalho com a linguagem cartográfica nas aulas de Geografia.

ILUSTRES ANÔNIMOS: IMPRENSA, INTELECTUAIS E A CIRCULAÇÃO DE IDEIAS EM MATO GROSSO (1880-1920)
Authors: Pinto Adriana Aparecida
Published: January 2020

Por meio da investigação histórica, o presente artigo indica possibilidades de análise da imprensa periódica de circulação geral, no que diz respeito à compreensão do papel dos intelectuais em um cenário comum – a configuração cultural do território mato-grossense entre os anos de 1880 a 1920. Parte-se da premissa que a imprensa deve ser colocada ao lado dos progressos materiais indicativos da modernidade,  que gradativamente chegaram ao território a partir da segunda metade do século XIX. Os jornais mato-grossenses difundiram os ideais das instâncias políticas e do poder, representados pelas famílias tradicionais, que se alternavam no poder e se ramificavam pelas municipalidades. No entanto, os jornalistas, categoria fluída em termos profissionais, desfrutavam de legitimidade social, pois se vinculavam à produção, circulação e divulgação de valores (MICELI, 2001), sendo também formadores de opinião e, na concepção que orienta este texto, intelectuais-mediadores/medidores culturais. Interessa discutir como profissionais de áreas distintas constituíram-se como editores, colaboradores, articulistas, integrando a categoria de intelectuais, partindo de uma conceituação proposta por Jean-François Sirinelli (1998, 2003).
O seriado Chaves e a questão urbana: exclusão, periferização e conflito de classes
Authors: Meira Júlio Cesar
Published: January 2020

Este texto propõe investigar o processo de periferização na cidade do México a partir da segunda metade do século XX, a partir da análise do seriado Chaves. Parte-se de duas interpretações. Em primeiro lugar, que esse processo de favelização e periferização foi parte da expansão urbana e industrial, na qual os mais pobres, os trabalhadores, ficaram à margem. Luta de classes, especulação imobiliária, concentração de renda, são alguns dos sintomas que geraram grandes massas de excluídos, que se concentraram em regiões precárias e distantes dos centros urbanos e econômicos, ainda que servindo de mão de obra a alimentar esse sistema. Em segundo lugar, que a exclusão e periferização pode se dar também no campo social, mesmo que convivendo os excluídos e privilegiados lado a lado ou no mesmo espaço. O recorte temporal, como apontado acima, abrange o período da segunda metade do século XX, com ênfase para a década de 1970.

Adesão à democracia e apartidarismo na América Latina: análise multidimensional
Authors: Gimenes Éder Rodrigo , Borba Julian
Published: January 2020

Dado o distinto contexto do desenvolvimento contemporâneo das relações dos eleitores com partidos políticos em regimes consolidados e em novas democracias, o presente artigo tem por objetivo avançar na identificação dos preditores da adesão à democracia na América Latina, por meio de modelos hierárquicos que incorporam tanto variáveis estruturais quanto aquelas de nível individual para a explicação do fenômeno, com destaque aos perfis de eleitores que consideram seu refinamento cognitivo e político. Para tanto, construímos modelos que consideram tanto a tese do apartidarismo e a relevância da mobilização cognitiva, em termos individuais, quanto a experiência nacional decorrente do legado democrático. Nossos resultados permitem inferir, por um lado, que o refinamento cognitivo dos eleitores é mais relevante do que o partidarismo com relação ao apoio que tais indivíduos manifestam com relação às diferentes dimensões da democracia, bem como, por outro lado, que a qualidade e a persistência do regime surtem impactos apenas sobre algumas dimensões da democracia.
Doutrina Bush e violência em In the Shadow of no Towers de Art Spiegelman
Authors: Rodrigues Danilo Pontes
Published: January 2020

O presente artigo buscou analisar questões geradas pelos atentados terroristas do dia 11 de setembro de 2001, assim como os seus desdobramentos, a partir de questões apresentadas pela história em quadrinhos In the shadow of no towers do quadrinista Art Spiegelman. Além de aspectos abordados a partir das medidas do governo Bush, o artigo contempla as questões quanto ao USA PATRIOT ACT, assim como as privações das liberdades individuais, processos que somente foram possíveis graças ao forte abalo que a sociedade passou após os atentados terroristas. O trabalho também contempla como Spiegelman abordou as guerras da Afeganistão e do Iraque, promovidas pelo governo estadunidense, criticando a violência promovida por este governo.

Published: January 2020

O objetivo deste trabalho é propor uma Tipologia para as Organizações Econômicas da Agricultura Familiar (OEAFs) do Brasil. A partir da base de dados SIES foi proposto uma Análise Fatorial Múltipla para se encontrar os eventuais Tipos de OEAFs. Foram determinados quatro Tipos. Posteriormente, foram feitas regressões logísticas com o objetivo de se verificar quais características socioeconômicas e regionais estavam mais relacionadas a cada um dos quatro Tipos encontrados. Os resultados sugerem que o Tipo 1 são OEAFs provenientes da Agricultura familiar, de áreas rurais, de organização gerencial menos complexa e de regiões mais pobres do Brasil. O Tipo 2 contempla OEAFs mais jovens, composta por cooperativas e também de regiões menos desenvolvidas do país. O Tipo 3 é caracterizado por cooperativas, Empreendimentos provenientes da Reforma Agrária, e região Norte do país. E, por fim, o Tipo 4 é marcado por OEAFs ainda mais jovens, Agricultura Empresarial, atividades não rurais e localizadas nas regiões economicamente mais dinâmicas do país. ABSTRACTThe objective of this paper is to propose a typology for the Economic Organizations of Family Agriculture (OEAFs) in Brazil. From the SIES database a Multiple Factor Analysis was proposed to find the possible types of OEAFs. Four Types were determined. Subsequently, logistic regressions were made in order to verify which socioeconomic and regional characteristics were most related to each of the four types found. The results suggest that Type 1 are OEAFs from family farming, from rural areas, from less complex managerial organization and from poorer regions of Brazil. Type 2 includes younger OEAFs, composed of cooperatives as well as less developed regions of the country. Type 3 is characterized by cooperatives, Enterprises from Agrarian Reform, and the northern region of the country. And, finally, Type 4 is marked by even younger OEAFs, Business Agriculture, non-rural activities and located in the most dynamic regions of the country. KEYWORDS: Typology, Economic Organizations, Family Agriculture, Brazil.
Exploring the Effectiveness of a Reading-dictation Task in Promoting Chinese Learning as a Second Language
Authors: Li Liu
Published: January 2020

Dictation has long been recognized as a valid testing device and practical teaching technique in second language (L2) teaching and research. Yet recent years have witnessed an increasing use of integrated tasks in language education. This paper attempts to combine dictation with a reading activity and thereby explores the effectiveness of a reading-dictation integrated task, as compared to a dictation-only task in facilitating Chinese learning as a L2. Results of a quasi-experimental study showed that in reading-dictation, participants produced a higher number of correct characters and made less use of pinyin for support; homophone errors and comprehension errors were noticeably reduced. In addition, feedbacks from an interview verified participants' positive attitudes towards the reading-dictation task. Pedagogical implications of this study were subsequently discussed, in relation to Chinese L2 teaching in general and orthography teaching in particular.

Visually impaired children within aged of 7–8 years old often face problems dealing with the adaptation in the environment. They have very low social skill and turn into dependence on their parents. Further, they need developing their self-confidence towards social skills. Mobility orientation, learning was one of the learning strategies that aimed to improve their social behavior in the environment. The purpose of this study was to develop the social skills of blind children in interacting with the environment and peers. This study involved a single subject research method (SSR) with A-B-A design. The subject of the study consisted of 3 blind children within 7–8 years old. The results showed that there was a significant improving in their social skills and independence during their daily lives. The female children tended to have some difficulties during the school activities compare with the male children. The family’s involvement is important to be used for helping them during the learning adaptation process with the environment. In short, the social skill development really matters for the blind children as they can imagine what kind of places where they are.
Thematic vs Chronological History Teaching Debate: A Social Media Research
Authors: Turan Ibrahim
Published: January 2020

At the beginning of the 19th century, history education has found its place as an independent course in formal education institutions, since then it has undergone many reforms and revisions but none of these reforms has solved its chronic problems. In discussions on how to solve the problems of teaching history, one of the most important issues is whether history should be taught chronologically or thematically. The purpose of this research is to review the discussions on this topic in Internet blogs to examine teachers’ views on the advantages and disadvantages of these two approaches. The social media research method was applied in this research. Required data obtained through teachers’ blogs on thematic and chronological history teaching and teachers’ comments on the subject in these blogs. The thematic content analysis carried out with the NVivo program, which helped in-vivo codes emerged from teachers’ blogs and comments. Most of the 71 teachers whose remarks are referenced in the research have expressed a positive view on thematic history teaching, although it is more difficult to understand and apply. Some teachers proposed a mixed approach in which the thematic and chronological approach is combined in different order and proportions based on students’ grades.

Diplura is a group of entognathous hexapods, often considered a sister group to insects. They play an important role in recycling organic matter in soil and subterranean terrestrial ecosystems. The Campodeidae is the most diverse family, divided into four subfamilies. The subfamily Plusiocampinae has a subterranean life-style with many species distributed in the Euro-Mediterranean area. The incertae sedis tachycampoids (“lignée Tachycampoïde”) is a group within the family Campodeidae that share with the Plusiocampinae a strong preference for subterranean habitats and several morphological characters, such as slender body shape, elongated appendages, considerable increment in the number of antennomeres and cercal articles, and complexity of sensorial structures. The present monograph provides a taxonomic revision of the subfamily Plusiocampinae and the genera belonging to the tachycampoid lineage from Europe and the Mediterranean region. It comprises detailed morphological descriptions and illustrations together with data on the habitats and distributions of 87 species, 10 subspecies and 11 affinis forms. Seven new species are described among those, namely: Plusiocampa (Plusiocampa) apollo Sendra, Giachino & Vailati sp. nov., P. (P.) chiosensis Sendra & Gasparo sp. nov., P. (P.) dublanskii Sendra & Turbanov sp. nov., P. (P.) hoffmanni Sendra & Paragamian sp. nov., P. (P.) rhea Sendra sp. nov., P. (P.) ternovensis Sendra & Borko sp. nov. and P.

A Comparative Analysis of Evidence-based Selection, Professional Selection, and Selection by Approval Plan
Authors: Strothmann Molly , Rupp-Serrano Karen
Published: January 2020

This study compares three different models for selecting e-books for a research library’s collection. From 2013 to 2018, the University of Oklahoma Libraries contracted with Elsevier for an evidence-based selection (EBS) agreement. The titles in that EBS package were compared to the approval plan parameters to determine which books would have been purchased on approval during those years if Elsevier had been included among the publishers profiled. Subject librarians also made hypothetical selections as though they were placing firm orders from this collection. The approval plan selections and librarians’ selections were compared to usage data to determine how closely each selection model matched patrons’ choices.
Holistic Collection Development and the Smithsonian Libraries
Authors: Abumeeiz Salma , Wingreen-Mason Daria
Published: January 2020

As part of a larger collections analysis study, this project outlines why a particular, underserved museum unit at the Smithsonian Institution is underutilizing the Smithsonian Libraries’ facilities and resources, and how the library can better support this unit’s unique research needs. Using a holistic methodology that weds quantitative and qualitative approaches, this study highlights the unit’s distinct research profile that includes the various logistical, emotional, and collection-related barriers that impede their usage of the Libraries. Findings from this study signal the utility of a holistic, user-centric methodology to gather pertinent data and facilitate ongoing, interpersonal dialogues between the Smithsonian Libraries and its diverse internal users.
