Authors: Ramadan S.I. , Manaa E.A. , El-Attrony M.E. , EL Nagar A.G.
Published: September 2020

The objectives of the present study were 1) to evaluate the polymorphism of growth hormone(GH), insulin-like growth factor 2 (IGF2) and progesterone receptor (PGR) genes in Sinai Gabali rabbits, and 2) to assess their associations with growth, litter size and milk production traits in Sinai Gabali rabbits. The C>T, A>Del and A>G single nucleotide polymorphisms of GH, IGF2 and PGR genes were genotyped by polymerase chain reaction-restriction fragment length polymorphism using BstUI, HpyF31 and BsaI restriction enzymes, respectively. The C/T genotype of GH gene recorded the heaviest body weights for body weight (BW) at 8 wk (1190.22±19.29 g) and 12 wk of age (1842.46±30.19 g) and recorded the largest litter size at birth (LSB: 7.37±0.12 kits) traits. The Del/Del genotype of IGF2 gene showed the superiority over the other genotypes for BW at 4 wk (507.17±8.87 g), 8 wk (1239.39±14.0 g), and 12 wk of age (1950.15±18.1 g), as well as for daily weight gain from 4 to 8 wk (26.05±0.37 g/d), and from 8 to 12 wk of age (25.48±0.56 g/d) traits. The G/G genotype of the PGR gene showed superiority for LSB (7.51±0.13 kits) and litter size at weaning (6.53±0.14 kits) traits over the other genotypes. Regarding milk yield traits; the C/C, A/A and A/A genotypes of GH, IGF2 and PGR genes yielded more milk compared to the other genotypes. The means of total milk yield in 28 d for these genotypes were 2936±29 g, 2921±43 g and 2930±35 g, respectively. Thus, GH, IGF2 and PGR genes might be useful for marker-assisted selection programmes for improvement of rabbit growth, litter size and milk yield traits.
Financial Literacy and French Behaviour on the Stock Market
Authors: Arrondel Luc
Published: September 2020

This article looks back over the different dimensions of financial literacy: theoretical, methodological, empirical and political. The theoretical foundations of the notion of financial literacy are presented with reference to recent contributions by psychological or behavioural economics: “household finance” refers to the concept of financial literacy based on the empirical dead-ends of standard saver theory. This raises the fundamental question as to how to measure and evaluate financial literacy. Here, we are especially interested in the empirical robustness of a standard measure of financial literacy based on three straightforward questions (interest calculations, notion of inflation and risk diversification). Is this measure adequate or do other definitions need to be developed? We use original data from a survey conducted in 2017 that proposes alternative measures. Our results show that the measure in most studies seems a good proxy for a more global measure based on a larger battery of similar questions. Nevertheless, the global measure improves the statistical quality of the measure even though this more sophisticated measure does not statistically significantly improve behavioural regressions.

Authors: Rasheed Sufian , Ullah Niamat , Ullah Amir
Published: September 2020

This is a quality control study and analysis of Portland cement taken from four Pakistani cement plants (Deewan, Kohat, Lucky and Maple Leaf). These four samples were analysed and the determination of major oxides present was carried out. Loss on ignition and the percentage of insoluble residue was also determined. Our research shows percentage of major oxides present in these four samples i.e. calcium oxide, silicon dioxide, aluminium oxide, iron oxide, sulphur trioxide and magnesium oxide. According to the American Society for Testing and Materials Cement (ASTM C150), the percentage of these oxides, loss on ignition and insoluble residue of these four plants are within the specified quality control range. The present study compared the quality of different oxides at the Portland cement brands in Pakistan. The percentages of SiO2,SO3, CaO, Al2O3,MgO and Fe2O3 were calculated according to American Society for Testing and Materials (ASTM C150) uniform standards. The percentages of all of the brands were within the limits specified by the standard (ASTM C150).

Published: September 2020

The experiment was conducted on alfalfa seeds that were brought from Marjajah in the city of Touggourt. After the traditional extraction process, some of its physical properties were measured, including, refractive index, pH, with a yellowish green color, odor, prick, and transport value of 363 cm/S and on blood clotting. The results showed that the seed extract of alfalfa has an effect on blood clotting on the internal and external pathway by the prothrombin rate (TP) obtained that sample 1 has the largest clotting time of 22 seconds and by the time of cefalin kaolin (TCK), the highest coagulation time for sample 2 by 46 seconds. The prothrombin rate and the time of cefalin kaolin chronometer tests also show that alfalfa seed extract exercises an important anticoagulant activity compared to the two coagulation methods, because this activity is more pronounced towards the internal pathway that the external pathway passes, that is, the alfalfa seed extract is better than the normal witness and less than the positive witness heparin.
Synthesis and crystallographic characterization of N-allyl-N-benzyl-4-methylbenzenesulfonamide
Authors: Stenfors Brock Anton , Ngassa Felix Nyuangem
Published: September 2020

N-Benzyl-4-methylbenzenesulfonamides were prepared via a two-step synthetic process involving the treatment of 4-methylbenzenesulfonyl chloride with a primary amine to give the corresponding 4-methylbenzenesulfonamide. Benzylation of the sulfonamide affords the substituted N-benzyl-4-methylbenzenesulfonamides. The similarities between the two steps of synthesis lend credence to the development of a one-pot synthesis of substituted N-benzyl-4-methylbenzenesulfonamides from 4-methylbenzenesulfonyl chloride. This method was applied to the synthesis of N-allyl-N-benzyl-4-methylbenzenesulfonamide and characterized through spectroscopic and crystallographic means. The crystal structure of N-allyl-N-benzyl-4-methylbenzenesulfonamide was obtained by single-crystal X-ray diffraction. The crystal structure reveals an orthorhombic Pna21 space group with cell parameters a = 18.6919 (18) Å, b = 10.5612 (10) Å, c = 8.1065 (8) Å, V = 1600.3 (3) Å3 and Z = 4, T = 173.15 K, μ(MoKα) = 0.206 mm-1, Dcalc = 1.251 g/cm3, 14455 reflections measured (4.36° ≤ 2Θ ≤ 54.96°), 3619 unique (Rint = 0.0439, Rsigma = 0.0429) which were used in all calculations. The final R1 was 0.0428 (I > 2σ(I)) and wR2 was 0.1079 (all data). Molecules are linked through C-H···N hydrogen bonds and C-H···π interactions.

Published: September 2020

Abstract. Global and regional chemical transport models of the atmosphere are based on the assumption that chemical species are completely mixed within each model grid box. However, in reality, these species are often segregated due to localized sources and the influence of the topography. In order to investigate the degree to which the rates of chemical reactions between two reactive species are reduced due to the possible segregation of species within the convective boundary layer, we perform large-eddy simulations (LES) in the mountainous region of the Hong Kong island. We adopt a simple chemical scheme with 15 primary and secondary chemical species including ozone and its precursors. We calculate the segregation intensity due to inhomogeneity in the surface emissions of primary pollutants and due to turbulent motions related to topography. We show that the inhomogeneity in the emissions increases the segregation intensity by a factor 2–5 relative to a case in which the emissions are assumed to be uniformly distributed. Topography has an important effect on the segregation locally, but this influence is relatively limited when considering the spatial domain as a whole.

Abstract. Column-averaged dry-air mole fractions of carbon dioxide (XCO2) and
methane (XCH4) measured by a solar viewing portable Fourier transform
spectrometer (FTS, EM27/SUN) have been characterized and validated by
comparison using in situ profile measurements made during the transfer
flights of two aircraft campaigns: Korea-United States Air Quality Study
(KORUS-AQ) and Effect of Megacities on the Transport and Transformation of Pollutants at Regional and Global Scales (EMeRGe). The aircraft flew over
two Total Carbon Column Observing Network (TCCON) sites: Rikubetsu, Japan
(43.46∘ N, 143.77∘ E), for the KORUS-AQ campaign and
Burgos, Philippines (18.53∘ N, 120.65∘ E), for the EMeRGe
campaign. The EM27/SUN was deployed at the corresponding TCCON sites during
the overflights. The mole fraction profiles obtained by the aircraft over
Rikubetsu differed between the ascending and the descending flights above
approximately 8 km for both CO2 and CH4. Because the spatial
pattern of tropopause heights based on potential vorticity values from the
ERA5 reanalysis shows that the tropopause height over the Rikubetsu site was
consistent with the descending profile, we used only the descending profile
to compare with the EM27/SUN data. Both the XCO2 and XCH4 derived
from the descending profiles over Burgos were lower than those from the
ascending profiles. Output from the Weather Research and Forecasting Model
indicates that higher CO2 for the ascending profile originated in
central Luzon, an industrialized and densely populated region about 400 km
south of the Burgos TCCON site. Air masses observed with the EM27/SUN
overlap better with those from the descending aircraft profiles than those
from the ascending aircraft profiles with respect to their properties such
as origin and atmospheric residence times. Consequently, the descending
aircraft profiles were used for the comparison with the EM27/SUN data. The
EM27/SUN XCO2 and XCH4 data were derived by using the GGG2014
software without applying air-mass-independent correction factors (AICFs).
The comparison of the EM27/SUN observations with the aircraft data revealed
that, on average, the EM27/SUN XCO2 data were biased low by 1.22 %
and the EM27/SUN XCH4 data were biased low by 1.71 %. The resulting
AICFs of 0.9878 for XCO2 and 0.9829 for XCH4 were obtained for
the EM27/SUN. Applying AICFs being utilized for the TCCON data (0.9898 for
XCO2 and 0.9765 for XCH4) to the EM27/SUN data induces an
underestimate for XCO2 and an overestimate for XCH4.
Carbon Export and Fate Beneath a Dynamic Upwelled Filament off the California Coast
Authors: Bourne Hannah L. , Bishop James K. B. , Connors Elizabeth J. , Wood Todd J.
Published: September 2020

Abstract. To understand the vertical variations of carbon fluxes in biologically productive waters, four autonomous Carbon Flux Explorers (CFEs) and ship-lowered CTD-interfaced particle-sensitive transmissometer and scattering sensors were deployed in a filament of offshore flowing recently upwelled water during the June 2017 California Current Ecosystem – Long Term Ecological Research process study. The Lagrangian CFEs operating at depths from 100–500 m yielded carbon flux and its partitioning with size from 30 µm–1 cm at three intense study locations within the filament and at a location outside the filament. Different particle classes (anchovy pellets, copepod pellets and > 1000 µm aggregates) dominated the 100–150 m fluxes during successive stages of the filament evolution as it progressed offshore. Fluxes were very high at all locations in the filament; below 150 m, flux was invariant or increased with depth at the two locations closer to the coast. Martin curve b factors for total particulate carbon flux were +0.1, +0.87, −0.27, and −0.39 at the three successively occupied locations within the plume, and in transitional waters, respectively. Particle transfer efficiencies between 100 to 500 m were far greater within both filament and California Current waters than calculated using a classic Martin b factor of −0.86. Interestingly, the flux profiles for all particles  90 %) of particle flux was carried by > 1000 µm sized aggregates. Mechanisms to explain a factor of three flux increase between 150 and 500 m at the mid plume location are investigated.
How Well do Models Represent the Development of Extra-Tropical Cyclones? Evaluation of Two General Circulation Models Against NAWDEX IOP 6 Observations

Published: September 2020

Abstract. The dynamical and microphysical properties of a well-observed cyclone from the North Atlantic Waveguide and Downstream impact Experiment (NAWDEX), called the Stalactite cyclone and corresponding to Intensive Observation Period 6, is examined using two atmospheric global circulation models: CNRM-CM6-1 and IPSL-CM6A. The hindcasts are performed in weather forecast mode, run at CMIP~6 resolution (LR) and c.~0.5° (HR) and initialized during the initiation stage of the cyclone. Cyclogenesis results from the merging of two relative vorticity maxima at low levels: one is associated with a Diabatic Rossby Vortex (DRV) propagating from the subtropics and the other is initiated by baroclinic development and interaction with a pre-existing upper-level PV cut-off. All hindcasts produce (to some extent) a DRV. However, the second vorticity maximum is almost absent in LR hindcasts because of an underestimated upper-level PV cut-off. The evolution of the cyclone is examined via the quasi-geostrophic ω equation, which separates the diabatic heating component from the dynamical one at each given time. In contrast with some previous studies, there is no change in the relative importance of diabatic heating with increased resolution. The analysis also shows that IPSL-CM6A produces a more active cyclone compared to the CNRM-CM6-1 due to stronger diabatism. To examine this further, hindcasts initialized during the mature stage of the cyclone are compared with airborne remote-sensing measurements. There is generally an underestimation of the ice water content in the model compared to the one retrieved from radar-lidar measurements, even when the liquid water content is added. Consistent with the increased diabatism in IPSL-CM6A compared to CNRM-CM6-1, the sum of liquid and ice water contents is higher in IPSL-CM6A than CNRM-CM6-1 and, in that sense, IPSL-CM6A is closer to the observations. However, ISPL-CM6A strongly overestimates the fraction of super-cooled liquid compared to the observations by a factor of approximately 50.
Ventriloquizing Mothers: Chaucer's Poetic Authority in the Tale of Melibee and the Manciple's Tale
Authors: Matlock Wendy A.
Published: September 2020

The Tale of Melibee and the Manciple's Tale provide vivid examples of Chaucer's polyphonic authority and highlight the rich network of gendered speech that constitutes his mature voice. A significant portion of both tales relates the direct discourse of women, namely Prudence and the Manciple's mother. Chaucer uses these ventriloquized women to transform continental sources into male English voices, articulating the (re)productive potential of the literary tradition in his native vernacular. Unlike the Wife of Bath (who famously has no children), neither woman addresses the pilgrims in her own voice: it is the Chaucer pilgrim, the Manciple, and Chaucer himself who derive authority via their imported wisdom. Recognizing the ventriloquism of maternal voices in Melibee and the Manciple's Tale reveals that both tales continue to debate the woman question and help to construct Chaucer as the representative voice of Middle English literature.

Academics’ “Why” of Knowledge-Building for the Fourth Industrial Revolution and COVID-19 Era
Authors: Khoza Simon Bhekumuzi
Published: September 2020

Online teaching results in knowledge building. Knowledge building is the teaching and learning process that helps academics and students to generate specific personal values used to understand their personal identities. Academics have been forced by COVID-19 lockdowns to go online in teaching their students. The purpose of this study is to explore and understand academics’ knowledge of teaching for knowledge building in two higher-education institutions (HEIs) (RSA and USA) during the COVID-19 era and the 4IR. Reflective activities, focus-group discussions, and semi-structured interviews were used for data generation. Purposive with convenience sampling was used to select the twenty most accessible academics to participate in this study. The findings reveal that this situation compelled the academics to self-actualise on their knowledge-building to address the “why” questions of teaching that help students to understand and address their needs. The self-actualization was framed by “technological pedagogical content knowledge” which produced societal, personal, and professional knowledge building. It was interesting to note that the USA HEI participants were supported by educational technologists, while the RSA HEI participants helped themselves. This was because the RSA HEIs do not have educational technology centres. Consequently, this study recommends a follow-up study that can qualitatively and quantitatively compare the two HEIs. In this way it can be established whether the success of online teaching and learning is influenced by the presence of educational technology centres.

Published: September 2020

CITYgreen Geographic Information Systems software was used to develop a campus wide cover type map for Stephen F. Austin State University in an environmental science landscape ecology course.  The finding indicated an equal division of forest cover type compared to impervious surface of buildings and paved surface.  Once the classification was completed, students chose an area for reforestation identified in CITYgreen, while raising funds for the purchase of trees for the project.  Before completing the project, students reviewed tenets of landscape ecology, civic ecology education, and benefits of urban forestry.  At the completion of the project, students reviewed service-learning aspects of campus beautification reflecting on making a difference, working outdoors, and using high end technology to complete a real-world environmental project incorporating partnerships and teamwork.  The outcome demonstrates the benefits of applying ecological planning to complete an environmental project based on a perceived need within a campus setting.
Anterior Cruciate Ligament Repair: Historical Perspective, Indications, Techniques, and Outcomes
Authors: Gee MAJ Shawn M. , Peterson CPT David R. , Zhou MAJ Liang , Bottoni Craig R.
Published: September 2020

Anterior cruciate ligament (ACL) repair was first reported in 1895 by Sir Arthur Mayo-Robson. Open primary ACL repair was performed throughout the 1970s and 1980s; however, rerupture rates were as high as 50% at mid-term follow-up. Throughout the 1980s and 1990s, synthetic graft materials received consideration; however, the outcomes were abysmal. Recently, with a better understanding of ACL healing and improvement in technique, there has been renewed interest in ACL repair. The potential advantages of ACL repair include improvements in knee kinematics and proprioception, avoiding graft harvest, and preserving bone stock. Although recent data on short-term outcomes suggest potential in properly indicated patients, medium- and long-term outcomes are largely unknown. ACL repair has the greatest potential in cases of proximal ACL rupture (modified Sherman type I and II proximal tears). Repair of midsubstance tears (modified Sherman type III tears) should be avoided. Caution is advised in athletes and younger patients because of higher failure rates. Today, ACL repair remains controversial and should be performed with caution because of limited medium- and long-term outcomes.

Prediction Skills, Reading Comprehension and Learning Achievement in Vihiga County Kenya. Addressing Constraints and Prospects
Authors: Anyiendah Mary Susan , Odundo Paul Amolloh , Kibuyi Agnes
Published: September 2020

Prediction skill may be used in reading comprehension passages as encapsulated in interactive approach instruction. Prediction skills assist learners to decode the meaning of comprehension passages by constructing guesses about the contents of texts to be read in comprehension passages. Learners in Vihiga County register low achievement in English language examinations than peers in neighbouring counties over the years. The performance is much weaker in comprehension passages than grammar sections. Although there are low grades, the nexus between use of prediction skills and learners’ achievement in reading comprehension passages has not been assessed. This study applied the Solomon Four Non-Equivalent Group Design to obtain primary data from 279 primary school learners and 8 teachers in 2017. Multiple linear regression used generated two models, one for the experimental group (Model 1) and one for the control group (Model 2). Findings indicate that the influence of prediction skills on learner achievement in reading comprehension passages was significant in experimental, but insignificant in the control groups. However, influence was stronger in the experimental than in the control groups, suggesting that training English language teachers on correct application of prediction skills improves learner achievement in reading comprehension passages. The study recommends need to: sensitise teachers on textbook usage, while supplementing with improvised materials; guide learners through titles; as well as update teacher training curriculum by integrating inter alia, emerging instructional methods embracing Information and Communication Technology and entrenching innovation in resource mobilization and use.

Microstructure Refinement for Fe-34Mn-10Al-0.76C Alloy Using Variable Pulsing Magnetic Field (PMF) Solidification
Authors: Almeshaiei Eisa A. , Ahmad Lubanah , Elgarhi Ibrahim
Published: September 2020

Background: The effect of the pulsed electromagnetic fields with different fluxes (voltages) on the microstructure of an alloy during all stages of solidification under specified thermal conditions will be discussed in this project. Experiments were carried out in the university laboratory for this purpose. The optical scanning, electron microscopy scanning, and dispersed X-ray analysis methods were used to analyze the results of the micro-solidification formulations of the alloy with different fluxes. To perform the required evaluation, a control sample was tested without any treatment, then the results of every flux were compared with the results of this control sample. The applied magnetics flux and Lorentz forces were considered as the main reasons for the achieved grain refining and diffusion of the improved solubility in the sample. The fully equiaxed dendritic structure has been realized for the aluminum alloys at 180 Volts flux. Lorentz's strong force, induced by the magnetic field, deactivates the developing direction of the bifurcation (dendrites), as well as spoils the directions of growing the intermetallic alloy, as a result of the formation of solid microstructures. Further refinements were achieved, by increasing the voltages. Therefore, it can be concluded that the pulsed electromagnetic field is a promising technique that can be utilized in the metallurgy evolution. The effect of PMF with different fluxes on the microstructure of the Fe-34Mn-10Al-0.76C alloy samples will be examined experimentally using optical scanning, EDX and SEM and by applying various analysis techniques. Then, compared with the control sample that don’t treated with any PMF. The initial dendrites growth direction and size were changed according to the PMF flux. Also, the lengths of the initial dendrites were reduced by increasing the voltage, which led to the formation of different dendrite equiaxed grains. The PMF flux affects the initial dendrites growth direction and size. While, increasing the PMF voltage reduces the lengths of the initial dendrites. Moreover, the PMF has a great impact on diffusion of solute through solidification that then influences the formation of eutectic microstructural.
Prioritisation and Localisation of Sustainable Development Goals (SDGs): Challenges and Opportunities for Bulawayo
Authors: Ndlovu Vinnet , Newman Peter , Sidambe Mthokozisi
Published: September 2020

Cities are engines of socio-economic development. This article examines and provides insight into the extent of localisation of the UN’s Sustainable Development Goals (SDGs) using the City of Bulawayo (CoB), in Zimbabwe, as the case study. The key question posited is ‘Does Bulawayo demonstrate potential for sustainable development?’. Bulawayo is a strange case study as in the period of the Millennium Development Goals Zimbabwe had a massive increase in death rates from 2000 to 2010 due to the HIV pandemic, political chaos and economic disintegration of that period. Coming out of that period there was little to help cities like Bulawayo grasp the opportunity for an SDG-based development focus. However, after the paper creates a multi-criteria framework from a Systematic Literature Review on the localisation of the SDG agenda, the application to Bulawayo now generates hope. The city is emerging from the collapse of the city’s public transport and water distribution systems, once the envy of and benchmark for many local authorities in the country, and has detailed SDG plans for the future. Bulawayo now serves as a planning model for localisation of sustainable development goals.
Compatibility of Eco-Friendly, Sustainable Living with Urbanization: A Case-study of The Art of Living International Center near Bengaluru
Authors: Kanchibhotla Divya , Rao Nupur , Harsora Prateek
Published: September 2020

In the past few decades, urban growth in most parts of the world has disregarded sustainable practices, contributing to a myriad of global problems. With 68% of the global population projected to reside in urban areas by 2050, it is essential that we espouse and implement effective sustainable solutions immediately. This study focuses upon the smart sustainable practices adopted at the international headquarters of The Art of Living near Bengaluru, the ‘Silicon Valley of India’. Situated in a rapidly urbanizing area barely 20 kms from the busy metropolis, and characterized by a large floating population that varies from 3,000-6000 visitors per week, apart from almost 2000 residents, this bustling community has lush green cover, extremely rich biodiversity and excellent air quality. Some of the sustainable practices adopted here include permaculture, efficient waste management, moving towards the use of clean energy, etc. This paper posits that this unique community exemplifies the possibility of creating an ‘oasis of sustainability’ in the arid desert of urbanization.

Published: September 2020

A mediação do desenvolvimento humano nas infâncias como construções históricas, afetivas e biológicas mobilizou a junção de duas interlocuções teóricas na educação: a biologia do conhecer e a educação das infâncias. O embasamento teórico do presente artigo teve como objetivo identificar os papéis que assumem os educadores das infâncias nas instituições educativas. Apresentar o panorama sistêmico dos processos de socialização na educação das/nas/com as infâncias ao longo da época possibilitou compreender que os contextos podem ser formais, não formais ou informais. Mas a educação é sempre educação, um direito essencial as infâncias nos ambientes educativos, em que os papéis dos educadores precisam estar implicados pelo ser, fazer e conversar com as crianças.
A interculturalidade crítica como alternativa para uma educação crítica e decolonial
Authors: Ramos Kellyane Lisboa , Nogueira Eulina Maria Leite , Franco Zilda Gláucia Elias
Published: September 2020

Este trabalho teve origem em um dos capítulos da dissertação de Mestrado, defendida no início de 2020. Cujo objetivo foi explicitar, com base em uma abordagem de pesquisa bibliográfica e crítica, a construção do termo intercultural e sua importância para uma educação crítica e decolonial. Tendo em vista a seguinte problemática: diante das diversas discussões sobre a diversidade cultural, a formação inicial do professor pode favorecer a valorização dos mais diversos conhecimentos culturais? Consideramos que, a despeito das discussões em torno da diversidade cultural, as culturas diversas ainda vivenciam desafios em relação ao reconhecimento e ao respeito às suas diferenças e especificidades. Para que ocorra a construção crítica da realidade, é mister que tenhamos uma educação pautada na valorização da cultura, partindo, a priori, da decolonização do conhecimento, na perspectiva da interculturalidade crítica, enquanto um projeto contra hegemônico. Assim sendo, aponta-se nas conclusões a necessidade de decolonizarmos o conhecimento no ambiente acadêmico, no Ensino Superior, especificamente na formação inicial de professores, a fim de que estes possam construir uma prática docente que contribua para um ensino crítico e emancipador em relação as questões culturais de diversidade. O que implica, que nessa construção a interculturalidade crítica se tem demonstrado como possibilidade para promover a emancipação crítica do indivíduo, por ser uma proposta de educação política, envolvendo uma concepção de ensino que possa contribuir para a transformação social, o que pode repercutir em uma sociedade com menos desigualdades e preconceitos.

O artigo objetiva analisar a percepção de docentes universitários sobre práticas de formação continuada de professores da educação básica. Refletindo a respeito das suas ações enquanto formadores nestes cursos, os docentes do ensino superior revelam que os cursos de formação de professores da educação básica são espaços privilegiados para se pensar formas de decolonizar o ensino. Realizamos entrevistas com coordenadores (as) de curso e formadores (as) universitários que atuaram em cursos de especialização ofertados pela Rede Nacional de Formação Inicial e Continuada de Profissionais da Educação Básica (RENAFORM), em 2014 na Universidade Federal Rural de Pernambuco (UFRPE) no Brasil. As políticas e propostas dos cursos eram de uma formação decolonial, no sentido que visavam a valorização de outros saberes, bem como dos sujeitos do campo, indígenas, negros, crianças, etc. As conclusões são que há limites no processo de implementação da referida política e fica claro que não basta um currículo decolonial, é preciso também uma prática. A universidade se enriquece com a possibilidade de compreender as demandas do chão da escola, bem como os professores do ensino básico são estimulados a prosseguirem no aprimoramento da sua formação, a nível de pós-graduação. Essa troca favorece a decolonialidade, constituindo-se em processo de construção que prevê redefinições tanto na configuração da profissionalidade docente como na produção do conhecimento nos cursos de formação continuada.

Published: September 2020

Discurso de ódio em redes sociais direcionado a minorias trazem hostilidade para este meio causando sofrimento e danos que vão além do mundo digital. Moderadores podem ajudar no controle de mensagens ofensivas, mas com o grande volume de mensagens publicadas é inviável realizar uma filtragem manual. Para tentar combater a propagação de mensagens de ódio de forma mais abrangente, este trabalho tem como objetivo utilizar análise de sentimentos para detecção de mensagens homofóbicas em português no Twitter. Os resultados da técnica desenvolvida foram comparados com as interpretações de humanos. Neste experimento, a técnica obteve 0,6148 de acurácia, 0,6667 de precisão, 0,6216 de sensibilidade e 0,6433 de f-measure.
Disconnecting for the good: A network-oriented model for social contagion of opinions and social network interventions to increase adherence to social distancing
Authors: Araújo Eric , Ferro Mariza , Silva Gabrieli
Published: September 2020

The pandemic of the new COVID-19 has raised many questions to a very connected society as to how to best respond to such a challenge at this current time. The best response so far is to call people for following the instructions from the World Health Organisation (WHO) as a way of reducing the spread of the virus and thus relieving the health system, striving to avoid a collapse. This work studies the spread of positive opinion on adhering to social distancing based on network topology and metrics using a network-oriented model for social contagion. It is shown that interventions based on social network measurements can be used to boost the spread of positive opinion about adhering to these measures. It is also shown that our model accounts for the relevance the health authorities have on encouraging people to partake in social distancing voluntarily.

Novas formas de relacionamento entre empresas e clientes foram introduzidas através do uso massivo de mídias sociais, e têm transformado a forma com a qual clientes tomam decisões de compras. Esta nova realidade explicitou a importância da análise do conteúdo relacionado a marcas e produtos publicados por consumidores em plataformas de mídias sociais. Nesse sentido, este artigo apresenta uma análise comparativa das duas maiores plataformas de reclamação online no Brasil, o ReclameAqui e o Consumidor.gov. Nas análises são utilizados os conteúdos provenientes de mineração de dados textuais de reclamações de cinco grandes empresas do setor de ecommerce brasileiro, com o objetivo de fornecer uma base para compreender os desafios e oportunidades nas análises destas mídias sociais em negócios. Os resultados mostram que a forma de atuação das empresas nessas plataformas deve ser especifica para cada plataforma, pois existem particularidades, tais como grupo de consumidores, conteúdo e principais tipos de problemas.
A Study of Rumor Detection based on Social Network Topic Models Relationship
Authors: Nolasco Diogo , Oliveira Jonice
Published: September 2020

The rumor detection problem on social networks has attracted considerable attention in recent years with the rise of concerns about fake news and disinformation. Most previous works focused on detecting rumors by individual messages, classifying whether a post or blog entry is considered a rumor or not. This paper proposes a method for rumor detection on topic-level that identifies whether a social topic related to a scientific topic is a rumor. We propose the use of a topic model method on social and scientific domains and correlate the topics found to detect the most prone to be rumors. Results applied in the Zika epidemic scenario show evidence that the least correlated topics contain a mix of rumors and local community discussions.

Authors: Pacifico Luciano D. S.
Published: September 2020

Neste trabalho, abordagens para a segmentação de doenças em imagens de folhas são apresentadas, como parte de um sistema automático de classificação de doenças em plantas. Para isso, Algoritmos Evolucionários (EAs), que sao meta-heurísticas de busca global, são adaptados como técnicas não supervisionadas de agrupamento de dados, no intuito de lidar com o problema. Quatro algoritmos foram selecionados e testados através do uso de doze imagens, que apresentam diferentes graus de doença, de modo a avaliar o quão robusto são tais modelos na solução do problema. A análise experimental revelou que as abordagens utilizadas são capazes de realizar de forma satisfatória a tarefa de segmentação das doenças nas imagens avaliadas.

Published: September 2020

Um excesso de informações não estruturadas está disponível em repositórios científicos, ocasionando problemas para recuperá-las, extraí-las e reutilizá-las. Para facilitar a recuperação de informações, foi proposto o uso de nanopublicação (NP), que ao utilizar tecnologias semânticas, evidencia dados importantes, facilitando a interpretação computacional e o reúso de afirmações. Neste artigo, propõe-se um método para a criação e recuperação de NPs. A validação do método é feita no domínio de Análise de Redes de Colaboração Científica, resultando em artefatos semânticos capazes de recuperar informações em um nível de granularidade menor.

Published: September 2020

As estações tradicionais de coleta de dados meteorológicos estão sendo substituídas por estações automatizadas, gerando uma maior quantidade de aquisição de informações. Entretanto, há também a maior probabilidade de erros como a ausência de dados, o que gera dificuldades na análise das pesquisas e na tomada de decisão dos processos. Tais falhas nos dados devem ser corrigidas para se obter uma base de dados de qualidade e possibilitar análises mais detalhadas e conclusivas. Existem métodos de preenchimento de falhas que realizam este trabalho. No entanto, cada método tem suas características e possuem desempenhos diferentes dependendo das particularidades das falhas. Este trabalho propõe uma metodologia com árvore de decisão para determinar qual método de preenchimento de falhas deve ser utilizado analisando uma série de dados meteorológicos, garantindo uma melhor qualidade no tratamento dos dados.

Published: September 2020

Bayesian phylogenetic algorithms are computationally intensive. BEAST 1.10 inferences made use of the BEAGLE 3 high-performance library for efficient likelihood computations. The strategy allows phylogenetic inference and dating in current knowledge for SARS-CoV-2 transmission. Follow-up simulations on hybrid resources of Santos Dumont supercomputer using four phylogenomic data sets, we characterize the scaling performance behavior of BEAST 1.10. Our results provide insight into the species tree and MCMC chain length estimation, identifying preferable requirements to improve the use of high-performance computing resources. Ongoing steps involve analyzes of SARS-CoV-2 using BEAST 1.8 in multi-GPUs.

Graph matching problems are well known and studied, in which we want to find sets of pairwise non-adjacent edges. Recently, there has been an interest in the study of matchings in which the induced subgraphs by the vertices of matchings are connected or disconnected. Although these problems are related to connectivity, the two problems are probably quite different, regarding their complexity. While the complexity of finding a maximum disconnected mat- ching is still unknown for a general graph, the one for connected matchings can be solved in polynomial time. Our contribution in this paper is a linear time algorithm to find a maximum connected matching of a general connected graph, given a general maximum matching as input.

Nos últimos anos, tem-se percebido um aumento significativo no uso de dispositivos móveis e aplicativos. Considerando o grande número de aplicativos, usuários enfrentam dificuldades em decidir qual instalar. Por outro lado, as provedoras de aplicativos enfrentam dificuldades para selecionar usuários para direcionar campanhas de marketing com o objetivo de aumentar a taxa de conversão. Neste trabalho, é proposta uma solução que faz a recomendação de aplicativos com base em dados de similaridades entre usuários e entre aplicativos, e também em informações demográficas da região de residência do usuário. Foi feita uma avaliação com dados reais de 7.406 usuários, e os resultados mostraram que a solução proposta se sobressaiu em até 14 pontos percentuais de precisão quando comparada com uma solução tradicional que não considera os dados demográficos. Além disso, a potencial taxa de conversão aumentou em até 30 vezes, quando comparada a usuários selecionados aleatoriamente.
