Pre-School Teacher Support and Retention of Pupils in Public ECDE Centres Kenya
Authors: Mwangi Caroline Wambui , Koross Rachael , Cheruiyot Betty
Published: December 2021

Pre-primary teachers need support from the government to ensure that they perform their instructional duties in the classroom effectively. With the devolving of Early Childhood Development Education from the national government to the county level, it was expected that this action would improve the standard and status of learning in these institutions. However, studies have shown that the expected reforms have been done at a slow pace affecting the achievement of ECDE objectives. This paper looks at the kind of support that teachers are provided with by the county government and its impact on the retention of pupils in public pre-primary schools in Wareng Sub County, Uasin Gishu County, Kenya. This study was conducted in 83 public pre-primary schools in Wareng Sub County, Uasin Gishu County. The study applied a descriptive survey research design with the target population involving 166 pre-school teachers and five county government ECDE field officers. The research instruments involved the use of questionnaires and interview schedules. Qualitative and quantitative approaches were used in data analysis. Research results showed that all respondents agreed that there has been a significant change in public pre-primary centres because of the devolution support. Correlation statistics showed that there existed a significant positive relationship between pre-primary teachers’ support and retention of pupils in public ECDE centres in Wareng Sub County, Kenya. The study recommends that additional pre-primary teachers should be employed in schools with a higher learner population and terms of employment should be permanent and pensionable.

Published: December 2021

This study aims to determine the best classification results among discriminant analysis, CART, and Adaboost CART on Bank X's Home Ownership Credit (KPR) customers. This study uses secondary data which contains notes on the 5C assessment (Collateral, Character, Capacity, Condition, Capital) and collectibility of current and non-current loans. The sample used in this study was from 2000 debtors. Comparison of classifications based on model accuracy, sensitivity, and overall specificity shows that Adaboost CART is the best method for classifying credit collectibility at Bank X. This is due to the class imbalance in the data. This study compares the classification results between parametric statistics, namely discriminant analysis and non-parametric statistics, namely CART and Adaboost CART. The results of the research can be used as material for consideration and evaluation for banks in determining the policy for providing credit to prospective borrowers from the classification results of KPR Bank X consumers.

Hegemonyanın kurulmasında rol oynayan unsurlar siyasi, askeri ve ekonomik olduğu kadar kültüreldir de. Bu fikirden yola çıktığımızda, çeşitli temsil dizgeleri ve bunların aktarımının önemi gözler önüne serilmektedir. Konuyu, en önemli temsil dizgelerinden biri olan dil bağlamında ele aldığımızda ise çeviri belli bir dilde yazılan kaynak metnin bir diğer dile aktarılarak, erek kültür dizgesinde kendisine bir yer edinmesi olarak düşünülmelidir. Edebiyat ve edebi çeviri de ağır ama emin adımlarla bir hegemonya kurmak ve bu hegemonyaya karşı çıkmak için en temel araçlardandır. Bu konuda alanda yazılan doktora tezinden hareketle kaleme alınan bu çalışmada, tezin üzerinden geçen on senede yaşanan kültürel, siyasi ve teknolojik gelişmeler ışığında İngilizce ve Anglo-Amerikan kültür ve Türkçe ve Türk kültürü çeviri açısından ele alınarak, özellikle John Fowles’un The French Lieutenant’s Woman [Fransız Teğmen’in Kadını], Jeanette Winterson’un Orange is Not the Only Fruit [Tek Meyve Portakal Değildir] ve Julian Barnes’ın England, England [İngiltere İngiltere’ye Karşı] eserlerinin çevirileri karşılaştırmalı olarak Venuti’nin çeviri stratejileri ve Gramsci’nin hegemonya kavramı çerçevesinde incelenmiştir.

THE ROLE OF DESIGNERS IN THE SOCIAL DESIGN DEVELOPMENT IN INDONESIA
Authors: Indriati Lisa
Published: December 2021

Designers have been active promoters who campaign for the wellbeing of life through the convenience and practicality created through design (Manzini, 2015). However, it has only recently been realized that the positive intentions discovered to be unsustainable that leads society to become very consumptive, thus causing a negative impact on the social, economic, and environmental problems we face today. Designers who are contributing to this problem need to be part of the solution, therefore it is necessary to develop tools or methodological frameworks to help designers get new ideas, develop solutions and utilize technology to create engaging sustainability initiatives for society. The major problem that society faces today is the lack of sensitivity to sustainable ways of living. Social problems play an important role in initiating the desired change, the power of design as a means to change behaviour into interests among the people, especially interests in the field of sustainable design or what is now commonly referred to as social design. The main purpose of the social design was to initially design products that require the least energy to produce and can be recycled. However, the development of massive industrialization produces a negative impact on the environment and society so that the development of social design shifts focus on things that affect change, the design must be able to change user behaviour.

Authors: Maharani Satyaning
Published: December 2021

ABSTRACT 

The Korean vocabulary card game Nolja is a game designed to assist the learning process of Korean vocabulary in an interactive way and suitable for women aged 15-25 years. However, as a new game, Nolja has a fatal problem with its design, namely, the placement of illustrations on the player card which makes the game finish too quickly, there are no tools to assess language proficiency on the card, the typeface on the card is less legible, and strokes on the illustration are too thin, Therefore, it is necessary to design a visual asset for the Nolja vocabulary card game. Visual asset design for Nolja includes game theme design, illustration, educational game system, layout, and content arrangement. This design aims to produce a Nolja card game design that is interactive, educational, and suitable for women aged 15-25 years who have the motivation and function to convey Korean language subject matter well. The design is carried out by qualitative methods through interviews with experts and extreme users in the game and learning the Korean language, distributing surveys to 100 target markets. This design is also supported by data collection from literature studies from books, journals, and articles from the Internet. The design produces a visual asset for the Nolja vocabulary card game with a stronger educational game system and a design style that matches the target market's wishes so that it can be well received by the market.

Osmanlı Devleti’nde 1704 Yılı Sikke Tashihi ve Fiyatlara Etkisi
Authors: DANIK Sevda
Published: December 2021

Osmanlı klasik döneminde madeni para rejimi hâkim olduğundan piyasada kırkık, vezni ve ayarı düşük paralar çoğalınca fiyatlar yükselir, alım gücü azalırdı. Bu durum esnaf ve halk arasında anlaşmazlıklara yol açar; ayrıca vergi tahsildarlarının bu paraları almak istememesi halkın şikâyetine, askerlerin maaşının bu ayarı düşük paralarla ödenmek istenmesi ise isyanlara sebep olurdu. Bu nedenle tedavülde bulunan paralar toplanarak belli bir standart üzerinden tekrar piyasaya sürülür ve bu işleme “sikke tashihi” denirdi. Paraların standartlaştırılmasıyla fiyatlar yeniden tespit edilir ve belirli oranlarda düşürülürdü. 1589, 1600, 1618, 1624 ve 1640’da sikke tashihleri yapılmıştır. 1600 ve 1640’da yapılan tashihlerden sonra narh defterleri oluşturulmuş, çeşitli gıda ve eşyaların fiyatı düşürülmüştür. 1704 yılında da önemli bir sikke tashihi yapılmıştır. Bu çalışmada 1704 yılında yapılan sikke tashihi incelenmiştir. Tashih öncesinde paranın durumu ve bu tashihten sonra verilen narhlar incelenmiş, tashih öncesindeki fiyatlar ile tashih sonrasındaki fiyatlar karşılaştırılmış; fiyat düşüşlerinin hangi oranlarda ve hangi maddeler üzerinde yapıldığı, hangi şehirleri ne oranda etkilediği tespit edilmeye çalışılmıştır.

Exciting Mutual Inclination in Planetary Systems with a Distant Stellar Companion: The Case of Kepler-108
Authors: Xu Wenrui , Fabrycky Daniel
Published: December 2021

We study the excitation of mutual inclination between planetary orbits by a novel secular-orbital resonance in multi-planet systems perturbed by binary companions, which we call “ivection.” The ivection resonance happens when the nodal precession rate of the planet matches a multiple of the orbital frequency of the binary, and its physical nature is similar to the previously studied evection resonance. Capture into an ivection resonance requires encountering the resonance with slowly increasing nodal precession rate, and it can excite the mutual inclination of the planets without affecting their eccentricities. We discuss the possible outcomes of ivection resonance capture, and we use simulations to illustrate that it is a promising mechanism for producing the mutual inclination in systems where planets have significant mutual inclination but modest eccentricity, such as Kepler-108. We also find an apparent deficit of multi-planet systems that would have a nodal precession period comparable to the binary orbital period, suggesting that ivection resonance may inhibit formation of or destablize multi-planet systems with an external binary companion.
Chromium Stable Isotope Panorama of Chondrites and Implications for Earth Early Accretion

Published: December 2021

We investigated the stable isotope fractionation of chromium (Cr) for a panorama of chondrites, including EH and EL enstatite chondrites and their chondrules and different phases (by acid leaching). We observed that chondrites have heterogeneous δ
53Cr values (per mil deviation of the 53Cr/52Cr from the NIST SRM 979 standard), which we suggest reflect different physical conditions in the different chondrite accretion regions. Chondrules from a primitive EH3 chondrite (SAH 97096) possess isotopically heavier Cr relative to their host bulk chondrite, which may be caused by Cr evaporation in a reduced chondrule-forming region of the protoplanetary disk. Enstatite chondrites show a range of bulk δ
53Cr values that likely result from variable mixing of isotopically different sulfide-silicate-metal phases. The bulk silicate Earth (δ
53Cr = –0.12 ± 0.02‰, 2SE) has a lighter Cr stable isotope composition compared to the average δ
53Cr value of enstatite chondrites (–0.05 ± 0.02‰, 2SE, when two samples out of 19 are excluded). If the bulk Earth originally had a Cr isotopic composition that was similar to the average enstatite chondrites, this Cr isotope difference may be caused by evaporation under equilibrium conditions from magma oceans on Earth or its planetesimal building blocks, as previously suggested to explain the magnesium and silicon isotope differences between Earth and enstatite chondrites. Alternatively, chemical differences between Earth and enstatite chondrite can result from thermal processes in the solar nebula and the enstatite chondrite-Earth, which would also have changed the Cr isotopic composition of Earth and enstatite chondrite parent body precursors.

We present an improved weak-lensing (WL) study of the high-z (z = 0.87) merging galaxy cluster ACT-CL J0102–4915 (“El Gordo”) based on new wide-field Hubble Space Telescope imaging data. The new imaging data cover the ∼3.5 × ∼3.5 Mpc region centered on the cluster and enable us to detect WL signals beyond the virial radius, which was not possible in previous studies. We confirm the binary mass structure consisting of the northwestern (NW) and southeastern (SE) subclusters and the ∼2σ dissociation between the SE mass peak and the X-ray cool core. We obtain the mass estimates of the subclusters by simultaneously fitting two Navarro–Frenk–White (NFW) halos without employing mass–concentration relations. The masses are

Accreting neutron stars in low-mass X-ray binaries show outflows—and sometimes jets—in the general manner of accreting black holes. However, the quantitative link between the accretion flow (traced by X-rays) and outflows and/or jets (traced by radio emission) is much less well understood for neutron stars than for black holes, other than the general observation that neutron stars are fainter in the radio at a given X-ray luminosity. We use data from the deep MAVERIC radio continuum survey of Galactic globular clusters for a systematic radio and X-ray study of six luminous (L
X > 1034 erg s−1) persistent neutron star X-ray binaries in our survey, as well as two other transient systems also captured by our data. We find that these neutron star X-ray binaries show an even larger range in radio luminosity than previously observed. In particular, in quiescence at L
X ∼ 3 × 1034 erg s−1, the confirmed neutron star binary GRS 1747–312 in Terzan 6 sits near the upper envelope of the black hole radio/X-ray correlation, and the persistently accreting neutron star systems AC 211 (in M15) and X1850–087 (in NGC 6712) show unusual radio variability and luminous radio emission. We interpret AC 211 as an obscured “Z source” that is accreting at close to the Eddington limit, while the properties of X1850–087 are difficult to explain, and motivate future coordinated radio and X-ray observations. Overall, our results show that neutron stars do not follow a single relation between inflow and outflow, and confirm that their accretion dynamics are more complex than for black holes.
Maximum Absorption of the Global 21 cm Spectrum in the Standard Cosmological Model
Authors: Xu Yidong , Yue Bin , Chen Xuelei
Published: December 2021

The absorption feature in the global spectrum is likely the first 21 cm observable from the cosmic dawn, which provides valuable insights into the earliest history of structure formation. We run a set of high-resolution hydrodynamic simulations of early structure formation to assess the effect of nonlinear structure formation on the maximum absorption level (i.e., assuming the spin temperature coupling is saturated) of the global 21 cm spectrum in the standard cosmological framework. We ignore the star formation and feedbacks, which also tend to reduce the absorption signal, but take into account the inevitable nonlinear density fluctuations in the intergalactic medium (IGM), shock-heating, and Compton-heating, which can reduce the absorption level. We found that the combination of these reduced the maximum absorption signal by ∼15% at redshift 17, as compared with the homogeneous or linearly-fluctuating IGM. These effects have to be carefully accounted for when interpreting the observational results, especially when considering the necessity of introducing new physics.
Population Properties of Neutron Stars in the Coalescing Compact Binaries

We perform a hierarchical Bayesian inference to investigate the population properties of the coalescing compact binaries involving at least one neutron star (NS). With the current gravitational-wave (GW) observation data, we can rule out none of the double Gaussian, single Gaussian, and uniform NS mass distribution models, though a specific double Gaussian model inferred from the Galactic NSs is found to be slightly more preferred. The mass distribution of black holes (BHs) in the neutron star–black hole (NSBH) population is found to be similar to that in the Galactic X-ray binaries. Additionally, the ratio of the merger rate densities between NSBHs and BNSs is estimated to be ∼3:7. The spin properties of the binaries, though constrained relatively poorly, play a nontrivial role in reconstructing the mass distribution of NSs and BHs. We find that a perfectly aligned spin distribution can be ruled out, while a purely isotropic distribution of spin orientation is still allowed. To evaluate the feasibility of reliably determining the population properties of NSs in the coalescing compact binaries with upcoming GW observations, we perform simulations with a mock population. We find that with 100 detections (including BNSs and NSBHs) the mass distribution of NSs can be well determined, and the fraction of BNSs can also be accurately estimated.

Published: December 2021

The presence of amphibian larvae is restricted by both biotic and abiotic variables of the environment. Some of these variables are still undetermined in the septentrional eastern Palearctic where Rana amurensis, Strauchbufo raddei and Dryophytes japonicus are found in large numbers. In this study, we sampled 92 sites across Mongolia, Russia and the Democratic People’s Republic of Korea and measured biotic and abiotic water variables, as well as the height of flooded terrestrial and emergent aquatic vegetation at the breeding site. We determined that the presence of anuran larvae is generally, but not always, linked to pH and temperature. Rana amurensis was not significantly affected by any of the variables measured, while S. raddei was impacted by water conductivity and D. japonicus by pH, temperature and vegetation. Our results highlight a potential risk for these species due to the changes in aquatic variables in response to desertification.
Current limitations and future prospects of detection and biomonitoring of NIS in the Mediterranean Sea through environmental DNA

Published: December 2021

The biodiversity of the Mediterranean Sea is currently threatened by the introduction of Non-Indigenous Species (NIS). Therefore, monitoring the distribution of NIS is of utmost importance to preserve the ecosystems. A promising approach for the identification of species and the assessment of biodiversity is the use of DNA barcoding, as well as DNA and eDNA metabarcoding. Currently, the main limitation in the use of genomic data for species identification is the incompleteness of the DNA barcode databases. In this research, we assessed the availability of DNA barcodes in the main reference libraries for the most updated inventory of 665 confirmed NIS in the Mediterranean Sea, with a special focus on the cytochrome oxidase I (COI) barcode and primers. The results of this study show that there are no barcodes for 33.18% of the species in question, and that 45.30% of the 382 species with COI barcode, have no primers publicly available. This highlights the importance of directing scientific efforts to fill the barcode gap of specific taxonomic groups in order to help in the effective application of the eDNA technique for investigating the occurrence and the distribution of NIS in the Mediterranean Sea.

Cela amena le gouvernement de Paris à accorder l’indépendance au Vietnam, au Laos, et au Cambodge afin de rééquilibrer le rapport de force. Ces indépendances amenèrent de nombreux changements, dont la mise en place d’une aide matérielle qui permit aux États-Unis de s’installer à Saïgon. Mais la présence diplomatique américaine en Indochine entraîna une perte de la souveraineté de la France sur cet espace, ce qui la poussa à se désengager progressivement du conflit jusqu’au départ de ses forces en 1956.
L'automne de l'Afrique romaine
Authors: Stoehr-Monjou Annick
Published: December 2021

Dracontius, le poète le plus important d’Afrique vandale, ne décrit pas Carthage - il ne compose pas d’ ekphrasis  - mais il évoque bien la cité : la Carthage punique à travers des exempla historiques (Didon, les guerres puniques, les sacrifices d’enfants) ; le paysage urbain de la Carthage vandale à travers des indices épars mentionnant des monuments publics, avec un accent mis sur les remparts ( moenia ). Dracontius en offre une image très différente de celle de poètes plus jeunes que lui de l’ Anthologie Latine (Félix, Florentinus, Luxorius). Ils louent les rois vandales alors que Dracontius oriente son propos pour créer l’image d’une Carthage romaine, qui nie la rupture vandale ; mais cette image n’est pas idéalisée car Dracontius montre aussi un climat de tensions politico-religieuses.
L'automne de l'Afrique romaine
Authors: Mkacher Anis
Published: December 2021

Ce travail va s’intégrer dans une réflexion qui tente d’examiner l’apport des sources littéraires souvent méconnues, mal exploitées et parfois décriées à cause de l’aspect tardif de la rédaction de ces récits. Pour être plus précise, notre analyse va essayer de lever le voile concernant l’apport de ces sources arabes sur l’urbanisme et la composition du tissu urbain en Afrique du nord issu de l’Antiquité classique, en général, et de l’Antiquité tardive particulièrement. Le deuxième point, quant à lui, sera spécifiquement réservé à la lexicologie, afin de savoir quels mots sont utilisés. Replacer ainsi un mot dans son espace temporel est capital dans la compréhension. Particulièrement, l’accent sera mis sur la genèse des termes et la capacité des auteurs à créer une image matérielle à travers des mots issus de leur milieu intellectuel et régional. Enfin, la conclusion tentera d’apporter les résultats d’une telle démarche, notamment, l’apport et les limites de ces sources, sans oublier, évidemment d’annoncer les pistes que nous allons suivre dans des travaux ultérieurs.
La demande de mort anticipée : une crise partagée
Authors: Rochas Bruno
Published: December 2021

La démarche palliative plaide pour un accompagnement du patient dans une continuité de son histoire, en soutenant un projet de vie. Lors de ce parcours, une demande de mort anticipée, avec sa dimension tragique, peut aussi être perçue par ceux qui soignent comme un risque de rupture, qui peut raviver des angoisses de séparation, voire d’abandon de part et d’autre de la relation soignant-soigné. Cette demande est un appel qui n’attend pas une réponse, elle attend quelqu’un.
Budgets familiaux et salaires des ouvriers du textile de Barcelone (1856-1917)
Authors: Borderías Cristina
Published: December 2021

À Barcelone, pendant la première étape de l’industrialisation, la plupart des conflits entre patrons et travailleurs sont en rapport avec l’autonomie des ouvriers qualifiés, menacée par le nouveau système des usines, ou avec les changements dans les politiques de valorisation des rendements. Ces conflits se développent très tôt dans le secteur principal de l’industrialisation : le textile cotonnier et plus particulièrement le filage. Ce sont les ouvriers de ce secteur qui les premiers revendiquent un salaire dit « familial », avant que cette aspiration ne s’étende à toute la classe ouvrière barcelonaise. Nous savons comment les discours sur la capacité des salaires masculins à couvrir seuls la subsistance de la famille se sont progressivement répandus dans d’autres secteurs, avec l’appui des élites intellectuelles krausistes, hygiénistes et catholiques sociales. Mais nous connaissons peu leur portée réelle auprès des classes ouvrières de la seconde moitié du XIX e  siècle. Cet article analyse la diffusion de la figure du « gagne-pain » à Barcelone pendant la période 1856-1917, en s’appuyant sur la reconstitution des budgets familiaux des ouvriers du secteur textile, secteur le plus important de l’industrialisation catalane et barcelonaise.
Les administrations et leur rôle dans la diffusion des politiques en matière de propriété intellectuelle en Chine : analyse fondée sur un réseau de références entre documents de politiques publiques
Authors: Xiang Jianqin , Ma Feicheng
Published: December 2021

Les relations entre administrations contribuent de manière importante à la continuité de l’innovation politique et à la diffusion des politiques publiques. Cette étude vise à comprendre le rôle fondamental que jouent les administrations, en tant que conceptrices et promotrices des politiques publiques, dans l’innovation politique en matière de propriété intellectuelle et dans la diffusion de ces politiques en Chine. En nous appuyant sur des relations de références entre différents documents de politiques publiques, nous construisons un vaste réseau de diffusion des politiques chinoises en matière de propriété intellectuelle et présentons les tendances et les caractéristiques de cette diffusion. Les résultats montrent que la diffusion des politiques en matière de propriété intellectuelle en Chine est corrélée positivement à un certain nombre de propriétés des administrations concernées, par exemple leur position dans le réseau, leur degré d’autorité, le niveau de développement économique de la région où elles se situent et le caractère récent de la politique concernée, mais n’est pas corrélée de manière significative à la proximité géographique entre elles. Remarque à l’attention des praticiens Cette étude permet de comprendre comment les relations entre administrations influencent la diffusion des politiques publiques dans l’environnement politique particulier de la Chine. Elle apporte, dans ses conclusions, un éclairage sur le rôle des administrations dans la diffusion des politiques publiques, susceptible d’aider tout organisme public dans l’élaboration et la diffusion de ses politiques, et elle contribue aux travaux de recherche sur les relations entre administrations et l’innovation politique fondés sur l’exploration de textes et l’analyse quantitative.
Nourrir les pauvres : les quatre âges de l’aide alimentaire
Authors: Retière Jean-Noël
Published: December 2021

Cet article retrace l’histoire de l’aide alimentaire en France avec un regard particulier sur trois thématiques : la relation entre le monde associatif et l’action de l’État, la question des représentations des bénévoles à l’égard des usagers, leurs motivations et la représentation que peuvent en avoir d’autres acteurs. Enfin, l’article évoque aussi l’histoire récente, marquée par la multiplication des initiatives locales aux côtés des grands organismes que sont les Banques Alimentaires et les ong historiques.
État des lieux des inégalités de santé liées à l’alimentation : analyse quantitative
Authors: Julia Chantal , Baudry Julia , Touvier Mathilde , Hercberg Serge
Published: December 2021

Les inégalités sociales de santé sont reflétées en matière de nutrition, avec un continuum dans la distribution des comportements alimentaires, les populations plus vulnérables ayant des comportements alimentaires globalement moins favorables à la santé. La consommation de fruits et légumes en particulier montre des disparités importantes entre les groupes sociaux, et peut être considérée comme un marqueur social. Les politiques publiques, en se focalisant sur l’information nutritionnelle, peuvent contribuer à l’aggravation de ces inégalités. Il est donc essentiel d’accompagner l’information des populations par des mesures en faveur d’un environnement par défaut favorable à la santé, pour rendre évident et accessible un choix « sain ».
Incompressible limit of Euler equations with damping
Authors: Shi Fei
Published: December 2021

The Cauchy problem for the compressible Euler system with damping is considered in this paper. Based on previous global existence results, we further study the low Mach number limit of the system. By constructing the uniform estimates of the solutions in the well-prepared initial data case, we are able to prove the global convergence of the solutions in the framework of small solutions.
Byzantine-robust federated learning via credibility assessment on non-IID data
Authors: Zhai Kun ,   Key Laboratory of Embedded System and Service Computing (Tongji University), Ministry of Education, Shanghai 201804, China, Ren Qiang , Wang Junli , Yan Chungang
Published: December 2021

Federated learning is a novel framework that enables resource-constrained edge devices to jointly learn a model, which solves the problem of data protection and data islands. However, standard federated learning is vulnerable to Byzantine attacks, which will cause the global model to be manipulated by the attacker or fail to converge. On non-iid data, the current methods are not effective in defensing against Byzantine attacks. In this paper, we propose a Byzantine-robust framework for federated learning via credibility assessment on non-iid data (BRCA). Credibility assessment is designed to detect Byzantine attacks by combing adaptive anomaly detection model and data verification. Specially, an adaptive mechanism is incorporated into the anomaly detection model for the training and prediction of the model. Simultaneously, a unified update algorithm is given to guarantee that the global model has a consistent direction. On non-iid data, our experiments demonstrate that the BRCA is more robust to Byzantine attacks compared with conventional methods.
Multiple positive solutions for the Schrödinger-Poisson equation with critical growth
Authors: Chen Caixia , Qian Aixia
Published: December 2021

In this paper, we consider the following Schrödinger-Poisson equation

   \begin{document}$ \left\{\begin{aligned} &-\triangle u + u + \phi u = u^{5}+\lambda g(u), &\hbox{in}\ \ \Omega, \\\ & -\triangle \phi = u^{2}, & \hbox{in}\ \ \Omega, \\\ & u, \phi = 0, & \hbox{on}\ \ \partial\Omega.\end{aligned}\right. $\end{document}

where \begin{document}$ \Omega $\end{document} is a bounded smooth domain in \begin{document}$ \mathbb{R}^{3} $\end{document}, \begin{document}$ \lambda>0 $\end{document} and the nonlinear growth of \begin{document}$ u^{5} $\end{document} reaches the Sobolev critical exponent in three spatial dimensions. With the aid of variational methods and the concentration compactness principle, we prove the problem admits at least two positive solutions and one positive ground state solution.
Lutas por representação nas ocupações das escolas de São Paulo: embates em filmes documentários
Authors: Sena Ercio , Gusman Juliana
Published: December 2021

O artigo propõe refletir sobre a representação da luta estudantil a partir da análise de conteúdo de três documentários brasileiros: Espero tua (re)volta (2019), Escolas em luta (2017) e Lute como uma menina (2016). As obras retratam as experiências de secundaristas nas ocupações das escolas de São Paulo, em 2015, um dos acontecimentos políticos mais pungentes da nossa história recente. Ao destacar aspectos formais e de conteúdo dos filmes analisados, este trabalho evidencia articulações estabelecidas entre o campo da comunicação e da educação nesse contexto. Apresenta, ainda, implicações políticas de esforços representativos no embate por horizontes pedagógicos mais democráticos e populares.

Vozes & audiovisual: a crise do coronavírus e a cobertura do The Intercept Brasil no Instagram
Authors: Gruszynski Ana Cláudia , Lindemann Cristiane , Sanseverino Gabriela Gruszynski
Published: December 2021

O estudo toma como objeto empírico a cobertura do The Intercept Brasil (TIB) sobre o Coronavírus publicada como stories no Instagram com o objetivo de compreender como diferentes vozes são incorporadas nos conteúdos audiovisuais produzidos. O corpus foi composto por nove destaques presentes em seu perfil, totalizando 260 stories. Com base na pesquisa bibliográfica foram estabelecidos os parâmetros de análise e a pesquisa documental orientou a contextualização do objeto empírico, em abordagem qualitativa. Observou-se que as narrativas promovem a confiança e credibilidade no que é narrado a partir do olhar de testemunha que a câmera subjetiva aciona, levando o público a percorrer ambientes, observar locais e pessoas, interagir com sujeitos, constituindo registros de referencialidade reforçados pelo som direto. Os recursos de edição com a inserção de elementos textuais garantem o entendimento do que se passa sem o áudio ativado. A valorização de diferentes contribuições está alinhada com a proposta editorial do veículo e revela características como horizontalidade, participação e engajamento dos usuários. Os stories são utilizados para contar histórias, não servindo apenas como um modo de redirecionamento para seu site. A cobertura dá visibilidade a realidades que não costumam ganhar espaço em modelos de negócios tradicionais e foi impulsionada para o/no Instagram pelo cenário de pandemia e isolamento social.
