Authors: Teresa Giovanazzi
Published: August 2021

Increasing awareness about the impending ecological crisis urges pedagogical research to project itself into the future and promote the training of human resources that is both responsible and aware of the educational value associated with the Environment. This paper, without claiming to be exhaustive, considers some challenges to transform the conditions of people and ecosystems within a culture of sustainability. Identifying balanced and authentic ways to inhabit the Earth is primordial to achieve the aforementioned objective and imply promoting effective educational actions through a new mindset between responsibilities and shared values. The governance of the educational ecosystem shall be the starting point with a particular focus on educational professionals 0-6. To make these multifaceted challenges a reality, the development of skills for professionals working in the educational and training services of childhood should be considered first. This is an unprecedented opportunity for the construction of sustainable skills that support the development of educational professionals 0-6 to take care of the environment.

 

Per una cultura della sostenibilità. Riflessioni pedagogiche, professionalità educative 0-6

Assumere consapevolezza della rilevanza della crisi ecologica sollecita la ricerca pedagogica a proiettarsi nel tempo futuro, promuovendo una formazione delle risorse umane responsabile e consapevole del valore educativo dell’ambiente. Il presente contributo, senza pretesa di esaustività, si interroga sulle sfide di un cambiamento necessario nella prospettiva di migliorare le condizioni delle persone e degli ecosistemi, per una cultura della sostenibilità. Individuare modi più equilibrati e autentici per abitare la Terra implica promuovere azioni educative efficaci attraverso una nuova forma mentis, tra responsabilità e valori condivisi, muovendo dalla governance dell’ecosistema formativo con peculiare riferimento alle professionalità educative 0-6. Accostarsi alla realtà multiforme, a partire da chi opera nei servizi educativi e formativi dell’infanzia, richiede uno sguardo inedito nella costruzione di competenze sostenibili per lo sviluppo di professionalità educative 0-6 che sappiano prendersi cura dell’ambiente, nel segno dell’ecologia integrale.
Evaluating software tools to conduct systematic reviews: a feature analysis and user survey
Authors: Pellegrini Marta , Marsili Francesco
Published: August 2021

Systematic reviews are research synthesis methods increasingly used in educational research to support evidence-based decision making. The conduction of a systematic review is a complex process with several phases usually supported by software tools. These tools used at the international level are not currently common in the Italian educational research. This work describes four software tools used in the international educational research and evaluates their general functionality and specific features’ usability to conduct the systematic review phases of study screening and selection. For this purpose, this study uses two methods: a feature analysis (Kitchenham et al., 1997) and an expert survey (Harrison et al., 2020). The results of both investigation methods agree to consider Covidence and Rayyan the most functional software tools in conducting SR. Among the four tools, ASReview has the greatest potential for making the process of a SR more efficient.

 

Una valutazione dei software per condurre revisioni sistematiche: analisi delle caratteristiche e sondaggio a esperti

Le revisioni sistematiche sono metodi di sintesi di ricerca sempre più utilizzati in campo educativo al fine di supportare il processo decisionale basato su evidenze. La conduzione di una revisione sistematica, poiché complessa e su più fasi, è sovente supportata in ambito internazionale da software specifici attualmente poco diffusi nella ricerca educativa italiana. Il contributo presenta quattro software utilizzati nella ricerca educativa internazionale e valuta le funzionalità generali e l’usabilità di caratteristiche specifiche per condurre le fasi di screening e di selezione degli studi. A questo scopo lo studio impiega i metodi dell’analisi delle caratteristiche (Kitchenham et al., 1997) e del sondaggio ad esperti in revisioni sistematiche (Harrison et al., 2020) in campo educativo. I risultati di entrambi i metodi di indagine concordano nel ritenere Covidence e Rayyan gli strumenti più funzionali per condurre revisioni sistematiche, mentre ASReview risulta il software con maggiore potenzialità per rendere il processo più efficiente.
CIVES - Citizens Towards Sustainability. Emblematic results of a research
Authors: Bornatici Sara , Vacchelli Orietta
Published: August 2021

L. n. 92/2019 introduced the transversal teaching of civic education in schools of all levels from the 2020-2021 school year. This contribution, without any claim to being exhaustive, proposes an interpretative reflection starting from some data that emerged in the context of the CIVES research (CIttadini VErso la Sostenibilità) which started from the training course on sustainable development aimed at the referring teachers of civic education of 51 Brescia institutes. The observations collected in the group debates highlighted fundamental contextual data for setting educational interventions, in an overall situation that appears very heterogeneous. Culture of sustainability and solidarity citizenship constitute two possible interpretations of the legislative proposal, taken for the training of teachers.

 

CIVES - CIttadini VErso la Sostenibilità. Esiti emblematici di una ricerca

La L. n. 92/2019 ha introdotto dall’anno scolastico 2020-2021 l’insegnamento trasversale dell’educazione civica nelle scuole di ogni ordine e grado. Il presente contributo, senza alcuna pretesa di esaustività, prospetta una riflessione interpretativa a partire da alcuni dati emersi nell’ambito della ricerca CIVES (CIttadini VErso la Sostenibilità) che ha preso le mosse dal corso di formazione in tema di sviluppo sostenibile rivolto ai docenti referenti di educazione civica di 51 istituti bresciani. Le osservazioni raccolte nei dibattiti di gruppo hanno evidenziato dati contestuali fondamentali per impostare interventi educativi, in una situazione complessiva che appare assai eterogenea. Cultura della sostenibilità e cittadinanza solidale configurano due possibili chiavi di lettura della proposta legislativa, assunte per la formazione dei docenti.

EFFECTIVENESS OF PUBLIC MONITORING COMMISSIONS IN THE CONTEXT OF THE EPIDEMIC: SOME LEGAL AND TECHNICAL ASPECTS
Authors: Малолеткина Наталья Сергеевна
Published: August 2021

Автором рассматривается проблема эффективности деятельности членов общественных наблюдательных комиссий в период эпидемии. Особое внимание уделяется правовой основе деятельности членов общественных наблюдательных комиссий в учреждениях уголовно-исполнительной системы с учетом имеющихся ограничений, связанных с эпидемией. Согласно ст. 85 УИК РФ возможно введение режима особых условий в исправительных учреждениях для противодействия и нейтрализации негативных последствий от стихийных бедствий, различных оснований введения чрезвычайного положения, указанных в ст. 3 ФКЗ Российской Федерации «О чрезвычайном положении», групповых неповиновений осужденных и пр. Режим особых условий предусматривает возможность введения дополнительных ограничений в отношении осужденных к лишению свободы и корректировку организации деятельности подразделений администрации исправительного учреждения (ч. 2 ст. 85 УИК РФ). В статье предлагается повторно изучить уже имеющийся опыт ряда пилотных проектов, которые реализовывались в исправительных учреждениях, и по мере необходимости внедрить их для повышения эффективности общественного пенитенциарного контроля за обеспечением прав осужденных. Формулируются также предложения по совершенствованию уголовно-исполнительного и иного законодательства в этой сфере.

The article deals with the problem of the effectiveness activity of public monitoring commission members during the epidemic. Special attention is paid to the legal basis of the activities of public monitoring commissions members in the penal institutions, taking into account the existing restrictions associated with the epidemic. According to Article 85 of the Criminal Code of the Russian Federation, it is possible to introduce a regime of special conditions in correctional institutions to counteract and neutralize the negative consequences of natural disasters, various grounds for the introduction of a state of emergency specified in Article 3 of the Federal Criminal Code of the Russian Federation «On the State of Emergency», group disobedience of convicts, etc. The regime of special conditions provides for the possibility of introducing additional restrictions on persons sentenced to imprisonment and adjusting the organization of the departments activities of the penal administration (Part 2 of Article 85 of the Criminal Code of the Russian Federation). The article proposes to re-examine the existing experience of a number of pilot reform that were implemented in correctional institutions and, if necessary, to implement them to improve the effectiveness of public penitentiary control over the rights of convicts. Proposals are also formulated to improve the penal enforcement and other legislation in this area.
REVISITING THE TECHNICAL MEANS USAGE FOR DETECTING NARCOTIC DRUGS AND (OR) PSYCHOTROPIC SUBSTANCES IN PENAL INSTITUTIONS
Authors: Денисенко Олег Игоревич
Published: August 2021

Работа посвящена организационно-правовым аспектам использования технических средств для обнаружения наркотических и психотропных веществ в ИУ и СИЗО. Рассмотрены основные способы их поступления с акцентированием внимания на таком способе, как пронос наркотических средств и (или) психотропных веществ через контрольно-пропускной пункт различных субъектов. Выявлены проблемные аспекты досмотровых мероприятий, проводимых сотрудниками УИС ФСИН России на данном пункте. Проблема заключается в не урегулированном на сегодняшний день перечне используемых технических средств обнаружения наркотических средств и (или) психотропных веществ в процессе прохода лиц на территорию исправительного учреждения или следственного изолятора. В работе рассмотрены некоторые тактико-технические данные технических средств, которые используются таможенными органами, которые могут быть использованы и сотрудниками УИС. Предложены некоторые варианты решения рассматриваемых проблем путем внесения в нормативно-правовые акты Федеральной службы исполнения наказаний норм, устанавливающих порядок и условия использования технических средств по обнаружению наркотических средств и (или) психотропных веществ на контрольно-пропускном пункте людей.

The work is devoted to the organizational and legal aspects and the flow of narcotic drugs and (or) psychotropic substances into the territory of correctional institutions or pre-trial detention centers for convicts in various ways. The main methods of their receipt are considered, with an emphasis on such a method as bringing narcotic drugs and (or) psychotropic substances through the checkpoint of various subjects. The problematic aspects of the inspection activities at this point, which are carried out by penal employees, have been identified. The problem lies in the currently unregulated list of the use of technical means for detecting narcotic drugs and (or) psychotropic substances in the process of the passage of persons into the territory of a correctional institution or a pre-trial detention center. The paper considers some tactical and technical data of technical means that are used by customs authorities, which can serve as an example of their implementation in the penal system of Russia. Some options are proposed for solving the problems under consideration by introducing norms into the regulatory legal acts of the Federal Penitentiary Service of Russia that establish the procedure and conditions for the use of technical means for the detection of narcotic drugs and (or) psychotropic substances at the checkpoint of people.
Regional studies of fluid inclusions in Paleozoic sediments from southern Scandinavia
Authors: Jensenius Jrørgen
Published: August 2021

Fluid inclusions in diagenetic quartz and calcite have been investigated in order to determine minimum temperatures attained during diagenesis and obtain information on composition of porewaters in the Paleozoic sediments. Surface samples from Bornholm, Skane and Gotland and drill core samples from Frederikshavn 1, R0nde 1, N0vling 1, Abenra 1, Slagelse 1 and 0rslev 1 have been studied. Two major types of fluids are described: aqueous and hydrocarbon mixtures. The aqueous inclusions can roughly be divided into 3 different groups based on homogenisation temperatures with arithmetic means of 82°C (with a salinity around 25 eq. wt. % salts) and 136° and 175°C (with salinities around 5 eq. wt. % salts). The correlation of temperatures and salinities of porewater is tentatively explained by dehydration of clay minerals diluting the porewaters. The hydrocarbon inclusions, some of which fluoresce green-yellow, homogenize into the liquid phase at temperatures between -44° to + 138°C, and are only found in calcite veins from the Silurian of N0vling 1 and the Lower Ordovician Komstad limestone, Bornholm. With regard to the thermal history the data indicate that 1: major thermal maturation occurred in pre­Carboniferious times 2: all Cambro-Ordovician samples are post-mature with respect to hydrocarbon generation and 3: only small, dry gas potentials are present in the upper Silurian to Carbonifereous rocks.
The Helsingør diamicton

Published: August 2021

Deglaciation sequences comprising glaciolacustrine sediments overlain by till deposited in a subaqueous environment around the Danish coast of 0resund and in central Northeast Sjrelland are grouped into five facies (a, b, c, d and e ). Facies a and facies bare clays deposited from suspension fall out in ice dammed la­kes. Fades c comprise sand and gravel deposited by traction currents, wave action and sediment gravity flows. Facies d, which is interbedded with or overlies the glaciolacustrine beds, is a diarnicton deposited as flow till during the breakdown of stagnant icemasses. Facies e: THE HELSING0R DIAMICTON is a he­terogeneous, flamy diamicton of either NW-Scanian or Baltic provenance deposited by iceberg drop and dump processes in interaction with glaciolacustrine sedimentation.
The Helsingf.'lr diamicton was laid down primarily from floating icebergs into a partly ice dammed, partly landsurface confined basin at the very end of the Middle Weichselian during a transgression which built up high level coast lines up to 65 m a.s.l. in Skane. On northeastern Sjrelland deposition took place in the coastal areas at least up to 20 m above the present sealevel.
Sr isotope chemistry of contaminated Tertiary volcanic rocks from Disko, central West Greenland
Authors: Pedersen A. K. , Pedersen S.
Published: August 2021

The Sr isotope chemistry of 26 samples of Tertiary volcanic rocks from the Vaigat and Maligat Formations on Disko are presented together with 5 samples of potential sedimentary contaminants from Disko and Nugssuaq. The volcanic rocks include one primitive picrite; 11 basalts, 8 andesites, 4 dacites and 2 rhyolites. Except for two basalts, all the basaltic to rhyolitic rocks are distinctly enriched in radiogenic Sr and this together with petrographical observations is taken as evidence for reaction with crustal rocks. The widespread xenoliths and xenocrysts point to Mesozoic to early Tertiary sediments as the major contami­nants and a shale and a sandstone composition have accordingly been chosen as model contaminants. Assimilation and Fractional Crystallization (AFC) calculations indicate that mafic silicates were the predominant fractionating phases in the contaminated members of the Vaigat Formation, whereas plagioclase crystallization and equilibration played a dominant role in the contaminated members of the Maligat Formation. The Kuganguaq Member in the Vaigat Formation cannot be modelled with a shale contaminant, but easily with a sandstone contaminant, and one dacite sample in the Nordfjord Member of the Maligat Formation is best modelled with sandstone contaminant. For all the other rocks, there is evidence of a dominating shale contamination.
The most strongly contaminated rock on Disko analysed for Sr isotopes is a rhyolite from the Nordfjord Member, whereas another rhyolite showed evidence of less contamination but very extensive feldspar fractionation. None of the silica-enriched rocks on Disko appear to be formed by closed system fraction­ation of a basic uncontaminated magma.
Catalyzed and uncatalyzed procedures for the syntheses of isomeric covalent multi-indolyl hetero non-metallides: an account
Authors: Talukdar Ranadeep
Published: August 2021

Two or more indole molecules tailored to a single non-metal central atom, through any of their C2–7 positions are not only structurally engaging but also constitute a class of important pharmacophores. Although the body of such multi-indolyl non-metallide molecules are largely shared to the anticancer agent bis(indolyl)methane, other heteroatomic analogs also possess similar medicinal properties. This concise review will discuss various catalytic and uncatalytic synthetic strategies adopted for the synthesis of the non-ionic (non-metallic) versions of these important molecules till date.

The coronavirus disease 2019 (COVID-19) is a contagious respiratory tract infection caused by the betacoronavirus SARS-CoV-2. The World Health Organization declared the COVID-19 outbreak a pandemic on March 11, 2020. Since the COVID-19 pandemic started, more than 166 million patients have been tested positive worldwide with more than 3.4 million related death recorded. COVID-19 has a wide range of signs and symptoms. Hematological changes such as lymphopenia, thrombocytopenia, and coagulation disturbances are not unusual in patients with COVID-19. However, the mechanisms causing these changes are partially comprehended. Immune thrombocytopenia was identified to be among the hematologic autoimmune diseases seen in patients infected with SARS-CoV-2. This review summarizes the evidence on COVID-19-associated immune thrombocytopenia and the underlying mechanisms involved in its development.

Objectives. Classification on multiple criteria of Gram-negative bacilli (GNBs) according to antibiotic resistance. Material and method. Retrospective study (January 2017-December 2018) carried out in the Infectious Diseases Clinic from Craiova; GNBs were identified using the Vitek 2 automated system, which subsequently established their sensitivity to antimicrobials; GNBs were classified based on an arbitrary score from 1 (minimum) to 5 (maximum) based on the multiple antibiotic resistance index (MAR), the percentage of multidrug resistant strains (MDR) and the percentage of extended resistance strains (XDR). The final classification represents the sum of the points awarded for each category considered. Results. The following GNBs were considered: Escherichia coli (n = 720), Klebsiella pneumoniae (n = 335), Pseudomonas aeruginosa (n = 139), Proteus mirabilis (n = 60) and Acinetobacter baumannii (n = 29). MAR values are: Acinetobacter baumannii (Ab) – 0.6, Proteus mirabilis (Pm) – 0.52, Pseudomonas aeruginosa (Pa) – 0.51, Klebsiella pneumoniae (Kp) - 0.37 and Escherichia coli (Ec) – 0.23. The percentage of MDR strains is: Pm – 76.67%, Kp – 68.86%, Pa - 58.71%, Ec – 51.94% and Ab – 51.72%; XDR strains were identified for Ab - 17.24% and Pa – 6.47%. The final classification of GNBs is as follows: Pa – 12p, Ab - 11 p, Pm – 7p, Kp – 6p, Ec – 3p. Conclusions. Depending on the resistance profile on multiple criteria, the classification of the studied Gram-negative bacteria is as follows: Pa, Ab, Pm, Kp, Ec.
ALGUNS COMENTÁRIOS A RESPEITO DAS REFORMAS RECENTES NO FIES E OS DESAFIOS ATUAIS
Authors: Pires Manoel
Published: August 2021

O Fundo de Financiamento ao Estudante do Ensino Superior (Fies) é o principal programa de financiamento de ensino superior do Brasil. Para parte significativa da população, o crédito estudantil é a segunda decisão de consumo mais importante, perdendo apenas para a aquisição de um imóvel. Do ponto de vista teórico, a racionalidade para intervenção estatal nesse mercado é muito clara. A expansão da escolaridade média da população é um fator importante do desenvolvimento econômico, incentiva a maior produtividade da mão de obra, a inovação, a redução da criminalidade etc. As externalidades positivas são incontroversas. Além disso, esse é um mercado em que o crédito é extremamente escasso, pois a maior parte dos estudantes não possui condições de oferecer garantias adequadas e a renda futura
é muito incerta. Por essas razões, o sistema de crédito público subsidiado é a norma nesse segmento. Do ponto de vista prático, a implementação desses programas é um enorme desafio. Os subsídios são elevados e a taxa de inadimplência bastante significativa. Em vários casos, há perdão para dívidas após certo prazo de pagamento. Mesmo nas melhores experiências e nos modelos mais modernos o custo
fiscal é substancial.

O programa de crédito estudantil do governo federal para ajudar alunos carentes a ingressarem no ensino superior foi criado em 1976. Este programa entrou em crise em 1991 em decorrência da inexistência de recursos para conceder novos financiamentos, da ausência de mecanismos eficazes de cobrança do pagamento dos empréstimos
e das concessões acima de sua capacidade de crédito, tendo funcionado de maneira precária desde então, até ser descontinuado em 1997. Em 1999, o governo federal voltou a conceder crédito estudantil por meio do Fundo de Financiamento Estudantil (Fies), instituído pela Medida Provisória (MP) nº 1.827, de 27 de maio de 1999. Posteriormente,
essa MP foi transformada na Lei nº 10.260, de 12 de julho de 2001, que destina a concessão de financiamento a estudantes regularmente matriculados em cursos superiores não gratuitos e com avaliação positiva nos processos conduzidos pelo Ministério da Educação (MEC).

A NEW CLOSED FORM SOLUTION FOR DYNAMIC STABILITY ANALYSIS OF ROLLING AIRFRAMES HAVING ONE PAIR ON-OFF ACTUATOR
Authors: Karimi Jalal
Published: August 2021

In this paper, the dynamic stability analysis of a rolling airframe actuated by one pair ON-OFF actuator using linear theory is presented via developing a new closed form solution. The effect of discontinuous forcing term on rolling airframe stability is studied. In contrast to tricyclic motion with constant forcing term (constant non-homogeneous term) in which only the amplitude of nutation and precession is affected, it is found that ON-OFF control affects both amplitude and phase of nutation and precession motions. In the case of discontinuous control surface, there are two sources for resonance instability. Finally, through simulation results of closed form solutions, a comparison between airframe’ response to ideal and real ON-OFF command is achieved. The effect of ON-OFF control on angular motion is also evaluated.

With a growing network traffic Mobile Network Operators (MNO) looking for ways to increase network capacity and improve customer experience. One of the ways is to find the best parameters from the set defined by 3GPP. In the study, closed-loop MIMO was compared to open-loop MIMO on the LTE FDD network. Network performance was evaluated in 3 different scenarios: slow and fast-moving UE under different SINR levels and large scale on 2T2R and 4T4R cells. The result shows gains of using closed-loop and it is recommended to use it commercial LTE networks.
Gravitational-wave Signatures from Compact Object Binaries in the Galactic Center
Authors: Wang Huiyi , Stephan Alexander P. , Naoz Smadar , Hoang Bao-Minh , Breivik Katelyn
Published: August 2021

Almost every galaxy has a supermassive black hole (SMBH) residing at its center, the Milky Way included. Recent studies suggest that these unique places are expected to host a high abundance of stellar and compact object binaries. These binaries form hierarchical triple systems with the SMBH and undergo the eccentric Kozai–Lidov (EKL) mechanism. Here we estimate the detectability of potential gravitational-wave emission from these compact objects within the frequency band of the Laser Interferometer Space Antenna (LISA) and Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo detectors. We generate a post-EKL population of stars at the onset of Roche limit crossing and follow their evolution to compact object binaries. As a proof of concept, we adopt two metallicities, solar metallicity (Z = 0.02) and 15% of it (Z = 0.003). We demonstrate that over the observation timescale of LISA, black hole (BH) binaries (BH–BH) and white dwarf (WD) binaries provide the most prominent GW sources via the EKL-assisted merger channel. Systems involving neutron stars (NSs) are less observable but possibly abundant through different merger channels. Our population synthesis of BH–BH with Z = 0.02 (Z = 0.003) translates to ∼4 (24) events per year with LIGO within a 1 Gpc3 sphere. We also estimated the number of binaries visible in the LISA band within the inner parsec of our Galactic center (and possibly other galaxies) to be about 14–150 WD–WD, 0–2 NS–BH, 0.2–4 NS–NS, and 0.3–20 BH–BH.
Is Solar Minimum 24/25 Another Unusual One?
Authors: Li Huichao , Feng Xueshang , Wei Fengsi
Published: August 2021

Solar minimum 23/24 is considered to be unusual because it exhibits features that differ notably from those commonly seen in previous minima. In this Letter, we analyze the solar polar magnetic field, the potential-field solution of the solar corona, and the in situ solar wind measurements to see if the recent solar minimum 24/25 is another unusual one. While the dipolar configuration that is commonly seen during minimum 22/23 and earlier minima persist for about half a year after the absolute minimum of solar cycle 24, the corona has a morphology that is more complex than a simple dipole before the absolute minimum. The fast solar wind streams are less dominant than minimum 23/24. The interplanetary magnetic field strength, density, and mass flux that are historically low in the minimum 23/24 are regained during minimum 24/25, but still do not reach the minimum 22/23 level. From the analysis of this Letter, it seems that the minimum 24/25 is only partly unusual, and the recovery of the commonly minimum features may result from the enhancement of the polar field.
Evidence for a Transient Emission Feature at 1524 Å in the Far Ultraviolet Spectrum of 21 Com
Authors: Monier Richard
Published: August 2021

Evidence is presented for the presence of a transient emission feature at 1524 Å in the far ultraviolet spectrum of 21 Com recorded by the International Ultraviolet Explorer during the 1979 event. This event is characterized by he sudden appearance of broad and intense absorption features shortwards of 1720 Å. The emission feature at 1524 Å is tentatively identified as a Si i line also present in the FUV spectra of quiescent dMe dwarfs. During the event, the flux level in the continuum adjacent to this line is about 1.6 times higher than in the mean spectrum outside event.
Belatedly Habitable Planets
Authors: Tuchow Noah W. , Wright Jason T.
Published: August 2021

Stars do not remain static, so their habitable zones evolve in time. Over a star's evolution, its habitable zone encompasses new planets, and it remains uncertain whether these planets can become habitable. We refer to this often overlooked class of planets as lying in the belatedly habitable zone, and stress that many planets found in the habitable zones of other stars will belong to this class. Future studies should take belated habitability into account and not implicitly assume that these planets are habitable.
Coexistence states of a Holling type II predator-prey system with self and cross-diffusion terms

Published: August 2021

In this paper, we present results about existence and non-existence of coexistence states for a reaction-diffusion predator-prey model with the two species living in a bounded region with inhospitable boundary and Holling type II functional response. The predator is a specialist and presents self-diffusion and cross-diffusion behavior. We show the existence of coexistence states by combining global bifurcation theory with the method of sub- and supersolutions.
Global well-posedness to the Cauchy problem of 2D inhomogeneous incompressible magnetic Bénard equations with large initial data and vacuum
Authors: Liu Zhongying ,   College of Mathematics, Changchun Normal University, Changchun 130032, China
Published: August 2021

In this paper, we are concerned with the Cauchy problem of inhomogeneous incompressible magnetic Bénard equations with vacuum as far-field density in $ \Bbb R^2 $. We prove that if the initial density and magnetic field decay not too slowly at infinity, the system admits a unique global strong solution. Note that the initial data can be arbitrarily large and the initial density can contain vacuum states and even has compact support. Moreover, we extend the result of [16, 17] to the global one.

Published: August 2021

In a bounded domain, we study the long time behavior of solutions of the stochastic three-component Gray-Scott system with multiplicative noise. We first show that the stochastic three-component Gray-Scott system can generate a non-autonomous random dynamical system. Then we establish some uniform estimates of solutions for stochastic three-component Gray-Scott system with multiplicative noise. Finally, the existence of uniform and cocycle attractors is proved.

We study the existence of solutions to the cubic Schrödinger system

   \begin{document}$ -\Delta u_i = \sum\limits_{j = 1}^m \beta_{ij} u_j^2u_i + \lambda_i u_i\ \hbox{in}\ \Omega,\ u_i = 0\ \hbox{on}\ \partial\Omega,\ i = 1,\dots,m, $\end{document}

when $ \Omega $ is a bounded domain in $ \mathbb R^4, $ $ \lambda_i $ are positive small numbers, $ \beta_{ij} $ are real numbers so that $ \beta_{ii} > 0 $ and $ \beta_{ij} = \beta_{ji} $, $ i\neq j $. We assemble the components $ u_i $ in groups so that all the interaction forces $ \beta_{ij} $ among components of the same group are attractive, i.e., $ \beta_{ij} > 0 $, while forces among components of different groups are repulsive or weakly attractive, i.e., $ \beta_{ij} < \overline\beta $ for some $ \overline\beta $ small. We find solutions such that each component within a given group blows-up around the same point and the different groups blow-up around different points, as all the parameters $ \lambda_i $'s approach zero.
To Be, or Not to Be Healthy
Authors: Belim Célia
Published: August 2021

This chapter, as the starting point of the book, (re)constructs the substantive setting and puzzle of health communication, being a reflection and discussion based on the literature review on fundamentals and practices of health communication and the contributions and implications of informative and persuasive messages and communication practices to health. The literature review results show the essential role that communication has assumed in the context of health, having several positive effects, such as the treatment effectiveness, the improvement of the therapeutic relationship and health literacy, the penetration of certain health issues in the public agenda. It has also highlighted the need to strengthen and rethink, in the name of individual and social well-being, the relationship between health and communication. Particularly, in the therapeutic relationship, the need for the health professional to have adequate communication competences to interact with patients is emphasized. Additionally, the media prove to be a versatile tool in the achievement of health promotion aims.
Communication on All Sides
Authors: Vaz de Almeida Cristina
Published: August 2021

People seek to solve problems, either through cognitive or emotional means or both, including behavioral ones. Health professionals have a specific mission to care and heal and they do so through their skills, behaviors, knowledge, and beliefs. To fulfill this mission of promoting satisfactory results in health relationships, the therapeutic relationship can be approached in several ways and based on different models. If there are trends of great centralization of consultation in the health profession, an effort has been made for patient-centered decision. The path of this relationship in health allows for a mutually beneficial interaction with commitment and better health results. Without wishing to be exhaustive and knowing that many models are left out, the authors explore the evolution of models applied to health throughout history.
It's All About the Heart
Authors: Belim Célia
Published: August 2021

This chapter aimed to provide responses, within the issue of cardiovascular health, to the effectiveness of the relation between the message's content (“what”) and form (“how”) and the triad of (cognitive-affective-behavioral) effects. The qualitative content analysis, concretely thematic and rhetorical types, was applied to a corpus of five ads from international campaigns (2015-2019) and three static Portuguese ads (2018-2019). One online survey of Portuguese university students (N = 55) was conducted. The findings show that the ads' issues vary from irreparable losses to the encouragement of healthy behaviors. The pathos tends to elicit various reactions (e.g., alarm, call to action, empathy, fear, guilt, hurt, worry). The logos are constructed of discursive devices (e.g., construction of a narrative, use of questions, selection of colors with connotative purposes, descriptions of concepts), evidence, and stylistic devices. Most of the respondents recognize the cognitive and affective influence, but not the behavioral effects.

Authors: Gómez-Ullate Martín , Barra Sanz Javier , Rodríguez Palacios Manuel
Published: August 2021

This chapter reflects on the understanding and measurement of development and rural development and on how music can influence it. Now more than ever, sustainability must direct development, and life quality indicators must be taken into consideration rather than income, growth, etc. From fieldwork, deep knowledge of different European contexts and a thorough state-of-the-art research, the chapter analyses cases and projects that have had relevant impact in their territories or may be considered for different reasons good practice cases. The aim of the chapter is to analyze those factors that may be considered to evaluate the quality and impact of a case. Researching, safeguarding, and recreating musical heritage produce impacts that go far beyond the economic aspects. Some of these aspects will be highlighted in this chapter. Results and conclusions will serve therefor to advance in research lines related to music tourism, musical heritage, and rural development, but will also be useful for managers, rural agents, local governments.
Deep Learning Based Sentiment Analysis for Phishing SMS Detection
Authors: Sharaff Aakanksha , Allenki Ramya , Seth Rakhi
Published: August 2021

Sentiment analysis works on the principle of categorizing and identifying the text-based content and the process of classifying documents into one of the predefined classes commonly known as text classification. Hackers deploy a strategy by sending malicious content as an advertisement link and attack the user system to gain information. For protecting the system from this type of phishing attack, one needs to classify the spam data. This chapter is based on a discussion and comparison of various classification models that are used for phishing SMS detection through sentiment analysis. In this chapter, SMS data is collected from Kaggle, which is classified as ham or spam; while implementing the deep learning techniques like Convolutional Neural Network (CNN), CNN with 7 layers, and CNN with 11 layers, different results are generated. For evaluating these results, different machine learning techniques are used as a baseline algorithm like Naive Bayes, Decision Trees, Support Vector Machine (SVM), and Artificial Neural Network (ANN). After evaluation, CNN showed the highest accuracy of 99.47% as a classification model.
Answer Selection in Community Question Answering Using LSTM

Published: August 2021

Websites like Quora, Yahoo! Answers, and Reddit are examples of community question answering (CQA) systems that enable users to ask questions as well as to answer questions. Answer selection is the most challenging task in CQA systems to get the good and relevant answer for the user questions. The shortcomings in the current approaches are lexical gap between text pairs, dependency on external sources, and manual features which lead to lack of generalization ability. These shortcomings are resolved by already proposed work, but they lack generalization, and their performance is not satisfying. Whereas to focus on rich quality answers, attention mechanism can be integrates with neural network. This chapter proposes two models BLSTM and BLSTM with attention mechanism. Attention mechanism aligns question to the answer with the answer's more informative part. So, when it is applied in the model, BLSTM with attention mechanism model surpasses the top approaches.
An Analysis on E-Learning and Its Recommendations
Authors: T. B. Lalitha , P. S. Sreeja
Published: August 2021

Education provides a predominant source of worldly knowledge around us and changes the perspective of the living society as a global village. However, education has revealed fragmentary remains in the professional competence and personal growth of the learners without the involvement of online learning. E-learning brings out a broader vision of sources to the learners available over the web with the holistic approach to learning from anywhere without cost and minimal effort. The proposed theoretical framework analyses the long-term evolution of e-learning and its effect on mankind. The various methods, technologies, and approaches of e-learning that exist in various forms were discussed exponentially according to the range of necessities among the learners. The recommendation system plays a pivotal role in referring contents and enhancing the learning environment. The education promoted to the learners through the recommendations system over their personal preferences were explored here in detail.
FNDNLSTM

Published: August 2021

In the present scenario, social media platforms have become more accessible sources for news. Social media posts need not always be truthful information. These posts are widely disseminated with little regard for the truth. It is necessary to realize the evolution and origins of false news patterns in order to improve the progression of quality news and combat fake news on social media. This chapter discusses the most frequently used social media (Facebook) and the type of information exchanged to solve this issue. This chapter proposes a novel framework based on the “Fake News Detection Network – Long Short-Term Memory” (FNDN-LSTM) model to discriminate between fake news and real news. The social media news dataset is to be taken and preprocessed using the TF BERT model (technique). The preprocessed data will be passed through a feature selection model, which will select the significant features for classification. The selected features will be passed through the FNDN-LSTM classification model for identifying fake news.
Sentiment Time Series Analysis on US Economic News
Authors: Kumar Vikas , Saritha Sri Khetwat
Published: August 2021

In the internet world we will have a lot of information, public opinions, and researchers' comments on the economy of a country, but it will be very difficult to analyze these opinions. Analysis of these opinions is very important to know how the economy of a country does change and to predict the economy of the country. Sentiment analysis does analysis of public opinion in the textual form, and it provides either of positive, neutral or negative sentiments of the textual comment given on the economy. Sometimes, sentiment analysis may not develop a model for better prediction and judgement of public opinion. In this chapter, the authors proposed a method that integrates sentiment analysis with the time series. They proposed a method to create a domain-specific lexicon to calculate the sentiment of the textual opinions over the economic dataset. This chapter implements the sentiment time series model on economic news by using the lexicon-based approach based on built-in lexicons and domain-specific lexicon.
Creating Brave Spaces
Authors: Johnson Nancy Kwang , Saito L. Erika
Published: August 2021

This chapter provides an interdisciplinary, conceptual social justice and social emotional learning framework and protocol to understand the varying competencies needed in critical learning paradigms with regard to multilingual learners (MLs). Engaging in social justice and social emotional (SJSE) work requires reflective practices to develop teacher identity. Therefore, reflection protocols before and after instruction in this chapter serve as a lever for building culturally reflective teachers through prompts that engage in self-awareness, student relations, and climate. Lesson plan delivery at different grade and language levels along with background and rationale of each topic further demonstrate SJSE integration. Discussion of challenges in SJSE are addressed that extend into three identified areas: professional, personal, and institutional.

Authors: Moore Ekaterina , Ferrario Kimberly
Published: August 2021

The chapter discusses creating an inclusive classroom through a language socialization perspective. The authors suggest that to create an inclusive culture in a multicultural and multilingual classroom, language educators should engage in explicit language socialization practices that promote development of critical cultural consciousness and language awareness. They propose that in the process of creating an inclusive classroom, educators need to attend to affective, individual, and interpersonal domains. Specific practices for use in a language (including ESOL) classroom and a teacher preparation program are provided.
