Do PCAOB Inspections Improve Working Capital Accrual Reliability? Evidence from the PCAOB Annual versus Triennial Inspection Exposure
Authors: Lee Cheol , Lee Jong Eun , Park Myung Seok
Published: February 2020

SYNOPSIS

In this study, we examine whether the ability of working capital (WC) accruals to predict future earnings and cash flows differs between registrants whose auditors are subject to annual Public Company Accounting Oversight Board (PCAOB) inspections and those whose auditors are subject to triennial PCAOB inspections. We find that WC accruals of clients audited by auditors subject to annual PCAOB inspections enhance earnings persistence more and map into future cash flow realizations better than those audited by auditors subject to triennial PCAOB inspections. These findings are stronger for operating asset accruals than for operating liability accruals. Furthermore, after PCAOB inspection reports are released, improvements in WC accrual reliability are more evident for clients audited by annually inspected auditors than for clients audited by triennially inspected auditors. Overall, our findings suggest that more frequent PCAOB inspections help to improve WC accrual reliability.

Demócrito e epicuro na tese doutoral (1841) de Marx
Authors: Roberto Damásio Marcos
Published: February 2020

Este trabalho tem como principal intenção apresentar a leitura de Marx do atomismo antigo, em sua Tese Doutoral, Diferença entre a filosofia da natureza de Demócrito e Epicuro, de 1841. Analisaremos as diversas diferenças entre os dois mais influentes pensadores dessa corrente filosófica, tanto na perspectiva de Marx, como na perspectiva das fontes utilizadas por ele. Embora ambos os filósofos estejam inseridos em uma mesma tradição de pensamento, eles sustentam doutrinas diferentes em diversos aspectos, por exemplo, a noção de peso, a declinação da linha reta e a teoria dos meteoros. Nossa exposição segue a mesma elaborada por Marx na redação de sua Tese, ou seja, serão analisadas primeiramente as diferenças gerais, isto é, acerca da natureza de ambas as pesquisas e suas relações com a realidade e o conhecimento, para em seguida analisar, de forma mais detalhada, as diferenças específicas, aquelas que enaltecem a filosofia de Epicuro sobre dois aspectos fundamentais, a saber, que sua teoria dos átomos não é mera repetição da teoria de Demócrito, com uma imensa parte da tradição o acusou, e que a “autoconsciência individual-abstrata” (abstrakt-einzelne Selbstbewußtsein) é seu verdadeiro princípio.
Fascismo e fascismo pós-fascista em Guy Debord e João Bernardo
Authors: Quintas Corrêa Erick
Published: February 2020

O presente artigo visa a uma discussão sobre o que Guy Debord (1931-94) diz sobre o fascismo em A sociedade do espetáculo (1967), através de um diálogo com a perspectiva teórica e conceitual de João Bernardo (1946 –) sobre a história dos fascismos. Visa, além disso, a fazer alguns apontamentos sobre os conflitos sociais que, principalmente a partir da crise sociopolítica e econômica de 2013-14, aceleraram o alinhamento do Brasil à ordem do “espetáculo integrado”, conceito desenvolvido por Debord nos Comentários sobre a sociedade do espetáculo (1988) e que o presente artigo busca relacionar com a categoria de “fascismo pós-fascista” apresentada por Bernardo em Os Labirintos do fascismo (2018).
Cooperación y conflicto entre Argentina y Brasil: las relaciones político-diplomáticas reflejadas en los medios gráficos argentinos de 2011 a 2015
Authors: Fabani Ornela , Insaurralde Gustavo , Sabattini Georgina
Published: February 2020

Tras el retorno a la democracia Brasil dejó de ser visto por la Argentina como un rival geopolítico para progresivamente transformarse en un socio deseable. Todavía más, dicha percepción mutó de manera tal que Brasil comenzó a ser juzgado como un actor indispensable para ampliar la autonomía nacional y fortalecer la inserción internacional de nuestro país. Este trabajo propone analizar las relaciones político-diplomáticas argentino-brasileñas a la luz de sus representaciones mediáticas, prestando atención a cómo los medios gráficos argentinos han dado cuenta de las mismas en términos de cooperación o conflicto, en el período 2011-2015. En cuanto al diseño de investigación, se mixturan componentes propios de un análisis cualitativo y cuantitativo. Finalmente, las fuentes empleadas en el análisis son tanto de carácter primario como secundario.
Political sociology and political management in the subject field of political science
Authors: Fedorkin N. S.
Published: February 2020

The article deals with the methodological problems of transformation processes in political science in the late XIX-th-early XX centuries and in the period between the two world wars. The author reveals the causes and origins of the crisis phenomena in political science due to the new political realities in the world and new trends in the political science development. The process of modern political science formation is analyzed in its gradual development (formal-legal, traditional, behavioral and post-behavioral). The special role of the Chicago revolution in political science, which created the environment and the ground for the emergence of the “behavioral” revolution, is revealed. The main program provisions of the “behavioral” revolution are indicated, its results, the main vectors of political science development in the post-behavioral era are revealed.

The role of structural functionalism (G. Almond and his school) in the formation of modern political science is revealed. The article deals with the interaction of political science with related social disciplines, which led to the emergence of some hybrid disciplines of political knowledge, including political sociology and political management. The content of the hybridization concept is revealed. The role of sociology in this process as the “main donor” of political science in the considered era is revealed. Object-subject areas of political sociology and political management, their place and role in the mechanism of socio-political systems functioning in the subject field of political science are defined. Generalizing conclusions are made.

Authors: Novoselova E. N.
Published: February 2020

The article analyzes the impact of lifestyle, tobacco smoking in particular, on health and life expectancy. Using the latest statistics, the author examines the problem of tobacco smoking in Russia and the world, describes the impact of this harmful habit not only on the health of the population, but also on the environment and the economy. The paper provides a brief history of tobacco control, describes modern anti-tobacco measures taken by the world community under the auspices of the World Health Organization (WHO).

Special attention is paid to the state of public opinion on issues related to the prevalence of tobacco smoking in Russia, its impact on the health and life expectancy of the population, the motivation of the population to abandon this habit and the impact on its presence / absence in social environment. It addresses the problem of child and adolescent smoking, analyzes the degree of parental influence and the likelihood that the child, in consequence, will become a regular smoker.

The author deals with the problem of passive smoking and the impact of secondary smoke on the health of children and adults, and notes that the anti-tobacco law adopted in Russia in 2013 undoubtedly reduced the number of passive smokers, which had beneficial effect on public health.

The work touches upon the currently relevant issue of Electronic Nicotine Delivery Systems (ENDS), provides usage statistics, and also raises the question of the consequences of the increasing popularity of ENDS.

The empirical base of the work is the data of WHO, the Federal State Statistics Service, the American Cancer Society, as well as studies of the Department of Sociology of Family and Demography (Faculty of Sociology, Lomonosov Moscow State University), the Public Opinion Foundation and the All-Russian Public Opinion Research Center.

This article will be of interest to specialists in the field of sociology of medicine, as well as to a wide circle of readers interested in the issues of addictive behavior and the formation of a healthy lifestyle.
Imaginaries of a ‘Europe of the regions’
Authors: Davoudi Simin
Published: February 2020

“I have not come here this evening to talk to you about a utopia; no, I am here to talk to you about an adventure ...: the federating of Europe.”

These are the words of Denis de Rougemont (1948, p.1), the Swiss philosopher and scholar, given at a talk on 22nd of April 1948 at the Sorbonne, Paris. He was advocating for the cultural, historical regions to become the sub-European political units instead of nation states. I start this essay with his statement not because I necessarily agree with his views, but because he is the person who coined the term ‘Europe of the regions’ in his book The idea of Europe, which appeared in English in 1966 (de Rougemont, 1966). Donald Tusk (2016), former President of the European Union (EU), called him “a philosopher of regionalism” and “a pioneer of the EU moto of ‘unity in diversity’”. I also started this essay with de Rougemont because of his take on what constitutes Europe. In his book, he traces the history of the idea from the Greek myth of the abduction of Europa by Zeus to the 18th and 19th century federalist ideas of Napoleon and the 1960s European Community, and concludes that the search for Europe is to build Europe; that, Europe is only to be found in the process of creating it (de Rougemont, 1966). This relational perspective somewhat resonates with what I am going to discuss about ‘the region’ and a ‘Europe of the regions’.

Мastocytosis is a heterogeneous group of disorders characterized by abnormal growth and accumulation of mast cells (MCs) in the skin and/or other organ systems. Mastocytosis is a rare disease. The annual incidence is 5-10 cases per 1 million people. However, the majority of cases stay undiagnosed due to the lack of specific tests and a wide variety of clinical features of the disease. In mastocytosis, somatic mutations of KIT gene lead to autocrine dysregulation and constitutive c-KIT activation in the absence of its ligand SCF. Clinical symptoms of the disease are determined by MC mediator release and/or infiltration of tissues by MCs. According to the World Health Organisation classification updated in 2016 mastocytosis is divided to cutaneous mastocytosis (CM), indolent systemic mastocytosis (ISM), smoldering systemic mastocytosis (SSM), SM with an associated hematologic (non-MC-lineage) neoplasm (SMAHN), aggressive SM (ASM), MC leukemia (MCL) and MC sarcoma (MCS). The CM and ISM prognosis is excellent with (almost) normal life expectancy, unlike aggressive forms (ASM and MCL) with poor prognosis. In this paper the key aspects of clinical features and diagnostic criteria of mastocytosis are discussed. We present a case report of a patient with mastocytosis in the skin following psoralen plus ultraviolet A (PUVA) therapy with good response.
DAMPAK PULUNG GANTUNG (PENCIPTAAN DENGAN METODE SENI GRAFIS)
Authors: Hernandi Kukuh
Published: February 2020

Pulung Gantung is one of the mythology in Kabupaten Gunungkidul which the community at there still believing as it is supported by some logic reasons until now. In the myth, Pulung Gantung always illustrated as a fire ball which dropped from the sky as a symbol of the happening of self-hanging. This story related with the reality where the statistic of self-hanging in Kabupaten Gunungkidul happened to be around 28 to 32 cases per year. This case became interesting where myth could be connected to the reality directly and it is still believed by many (in where this case also experienced different development of variety definition), which indirectly created variety layers of impact. The complexity of this theme and different perspectives to define attracted the artist to carry out research and apply the outcome with the method of printmaking as a way to process the impact of Pulung Gantung. With the method of printmaking, it progressively attracted to the definition of printmaking slowly returned to the early essence of printmaking itself as a media without limitation of conventional rules. This strongly supported the artist to apply this media on this topic to have an open discussion about the impact of Pulung Gantung with the presentation of different medium like sound, words or product. The artist creates the work in different medium, hopefully could become a vague stimulant for a better understanding about the myth and the reality of this topic. Nevertheless, other than understanding, there is potential for audience to have new idea or other’s perspective about this topic as the work presented in an indirectly way. In this case, the outcome of the work about the impact of Pulung Gantung creates the possibilities of different conclusion and new perspectives. With this idea, the possibility from the impact of mythology intersects with the reality which unconsciously continue to be happened.

Authors: Ashfaq Anum
Published: February 2020

Background:

Retinal migraine is a type of migraine with aura. It is a rare entity which presents as monocular symptoms, such as scotomas or blindness followed by headache phase of migraine. There are wide varieties of causes for monocular vision loss ranging from benign causes to very serious causes of blindness.

Case Presentation:

This is a case of 26-year-old female who presented with recurrent attacks of unilateral vision loss but it was not followed by headache which is a rare entity. On investigations, her complete blood picture, liver function tests, renal function tests, erythrocyte sedimentation rate, C-reactive protein, electrocardiography, echocardiography, anti-neutrophil antibody, carotid Doppler, and magnetic resonance imaging of brain were all normal.

Conclusion:

The diagnosis of retinal migraine was established and the patient was reassured and counseled in detail with the advice of follow-up.

Authors: Ghosh Arnab , Bhartiya Manish , Gupta Salil , VK Shashindran , Saxena Puneet
Published: February 2020

Background:

Klinefelter-syndrome (KS) is recognized as 47, XXY or XXY, two or more X chromosome in males giving rise to a set of clinical signs and symptoms. These individuals are predisposed to certain malignancies. The association of Hodgkinlymphoma (HL) with KS is very rare and reported only in a single case in literature. Moreover, it is extremely rare to have Chronic-Demyelinating-Inflammatory-Polyneuropathy (CIDP) as initial presentation of HL. The association of CIDP in HL in a case of Klinefelter-syndrome has never reported together.

Case Presentation:

We report a case of 47-year old Indian male who presented with CIDP and was eventually diagnosed with Nodular sclerosis variant of HL. Karyotyping revealed KS. Institution of treatment of HL improved his neurological symptoms. However, administration of androgens was deferred till the completion of chemotherapy. Unfortunately, he could not tolerate Chemotherapy and died of Renal Failure during the fourth cycle.

Conclusion:

This case report depicts an extremely rare combination of CIDP, HL with KS. It also signifies that all CIDP cases should be evaluated for occult malignancy and if malignancy is found patient should undergo karyotyping for under-diagnosed chromosomal abnormalities such as KS as in this case.

Published: February 2020

Fatores internos e externos influenciam a flexibilidade, dentre estes fatores destaca-se o gênero, pois as mulheres têm mais flexibilidade que os homens em detrimento da maior quantidade do hormônio estrógeno gerando menor desenvolvimento de massa muscular, diminuindo o atrito entre fibras musculares, sendo a responsável pela maior flexibilidade. A ventosaterapia é uma técnica milenar no qual seu tratamento é feito através de pressão negativa de ar sobre a pele com copos específicos. De uma forma geral, esta técnica produz efeitos nas várias estruturas do corpo humano como na pele, nos músculos, nas articulações e no sistema nervoso. A ventosaterapia tem suas aplicações subdivididas em cupping with retention, moving-cupping, shaking-cupping, quick-cupping. Foi utilizado o moving-cupping que é o deslizamento do copo sobre a pele criando um efeito de liberação muscular. Este estudo teve objetivo comparar a eficácia da Ventosaterapia e Alongamento Estático para ganho de flexibilidade em cadeia posterior em indivíduos hígidos, tendo como métodos avaliativos o teste de mão ao chão com Biofotometria e Banco de Wells. Foi realizado ensaio clínico cruzado randomizado dos indivíduos, composto por n=2 voluntários do sexo masculino com idade de 20-40 anos. Como métodos avaliativos foram usados a Biofotometria no software ImageJ e o Banco de Wells da marca Sanny no pré e pós-intervenção. Foram divididos 3 grupos por randomização, grupo ventosaterapia (VT), grupo ventosaterapia mais alongamento estático de um minuto (VT-AE) e grupo controle (CTRL). Voluntário 1 grupo VT: Biofotometria (Pré:116°/Pós:106°), Banco de Wells Pré: (262/Pós: 278); Grupo VT-AE: Biofotometria (Pré:95°/Pós:100°), Banco de Wells Pré: (244/Pós: 281); Grupo CTRL: Biofotometria (Pré:93°/Pós:95°), Banco de Wells Pré: (207/Pós:267). Voluntário 2 grupo VT: Biofotometria (Pré:83°/Pós:83°), Banco de Wells (Pré:250/Pós:298); Grupo VT-AE: Biofotometria (Pré:77°/Pós:86°), Banco de Wells (Pré:221/Pós:260); Grupo CTRL: Biofotometria (Pré:93°/Pós:86°), Banco de Wells (Pré:249/Pós:290). Através do estudo piloto o grupo VT não apresentou melhora na flexibilidade e os grupos VT-AE e CTRL tiveram aumento da flexibilidade no banco de wells.
Quadruplex Folding of DNA Promotes the Condensation of Linker Histones via Liquid-Liquid Phase Separation
Authors: Mimura Masahiro , Tomita Shunsuke , Shinkai Yoichi , Shiraki Kentaro , Kurita Ryoji
Published: February 2020

Liquid-liquid phase separation (LLPS) of proteins and DNA has recently emerged as a possible mechanism underlying the dynamic organization of chromatin. We herein report the role of DNA quadruplex folding in liquid droplet formation via LLPS induced by interactions between DNA and linker histone H1 (H1), a key regulator of chromatin organization. Fluidity measurements inside the droplets and binding assays using G-quadruplex-selective probes demonstrated that quadruplex DNA structures, such as the G-quadruplex and i-motif, promote droplet formation with H1 and decrease molecular motility within droplets. The dissolution of the droplets in the presence of additives indicated that in addition to electrostatic interactions between the DNA and the intrinsically disordered region of H1, π-π stacking between quadruplex DNAs could potentially drive droplet formation. Given that DNA quadruplex structures are well documented in heterochromatin regions, it is imperative to understand the role of DNA quadruplex folding in the context of intranuclear LLPS.
Single-Site Binding of Pyrene to Poly(ester-Imide)s Incorporating Long Spacer Units: Prediction of NMR Resonance-Patterns from a Fractal Model

Published: February 2020

Co-polycondensation of the diimide-based diols N,N'-bis(2-hydroxyethyl)hexafluoro-isopropylidene-diphthalimide, (HFDI), and N,N'-bis(2-hydroxy-ethyl)naphthalene-1,4,5,8-tetracarboxylic-diimide, (NDI), with aliphatic diacyl chlorides ClOC(CH2)xCOCl (x = 5 to 8) affords linear copoly(ester-imide)s. Such copolymers interact with pyrene via supramolecular binding of the polycyclic aromatic molecule at NDI residues. This results in upfield complexation shifts and sequence-related splittings of the NDI 1H NMR resonances, but gives a very different resonance-pattern from the corresponding copolymer where x = 2. Computational modelling of the polymer with x = 5 suggests that, in this system, each pyrene molecule binds to just a single NDI residue rather than to an adjacent pair of NDI's in a tight chain-fold ("dual-site" binding) as found for x = 2. The new single-site binding model enables the pattern of 1H NMR resonances for copolymers with longer spacers (x = 5 to 8) to be reproduced and assigned by simulation from sequence-specific shielding factors based on the fractal known as the fourth-quarter Cantor set. As this set also enables an understanding of dual-site binding systems, it evidently provides a general numerical framework for supramolecular sequence-analysis in binary copolymers.
Improving Molecular Design by Stochastic Iterative Target Augmentation

Published: February 2020

Generative models in molecular design tend to be richly parameterized, data-hungry neural models, as they must create complex structured objects as outputs. Estimating such models from data may be challenging due to the lack of sufficient training data. In this paper, we propose a surprisingly effective self-training approach for iteratively creating additional molecular targets. We first pre-train the generative model together with a simple property predictor. The property predictor is then used as a likelihood model for filtering candidate structures from the generative model. Additional targets are iteratively produced and used in the course of stochastic EM iterations to maximize the log-likelihood that the candidate structures are accepted. A simple rejection (re-weighting) sampler suffices to draw posterior samples since the generative model is already reasonable after pre-training. We demonstrate significant gains over strong baselines for both unconditional and conditional molecular design. In particular, our approach outperforms the previous state-of-the-art in conditional molecular design by over 10% in absolute gain.
Sinergicity test of silver nanoparticles and clindamycin against Staphylococcus aureus
Authors: Novi Haryanti  , Iskandarsyah  , Yeva Rosana
Published: February 2020

Acne is a chronic inflammatory disease. The pathogenesis of acne is multifactorial; one of them is caused by an overgrowth of microbes like S. aureus. Clindamycin is one of the antibiotics recommended for acne therapy. Still, the use of clindamycin causes various side effects such as changes in intestinal function associated with intestinal flora, pseudomembranous colitis, and increases the risk of resistance. Silver nanoparticles are potent antimicrobials, have broad-spectrum activity, and can reduce the development of resistance. Despite having potent activity, the long-term use of silver nanoparticles is reported to have side effects argyria. The use of antimicrobial combinations is a strategy to reduce side effects and increase the effectiveness of therapy. Antimicrobial combinations can use low concentrations but still have the potential to inhibit microbial growth. This research aim is to determine the antibacterial synergism of a combination of silver nanoparticles and clindamycin against S. aureus. Determination of the minimum inhibitory concentration (MIC) of silver nanoparticles, clindamycin, and synergism test was carried out by microdilution using 96-well microplates. Synergy test is carried out using the Checkerboard method by calculating the value of the Fractional Index Concentration (FIC). The results showed the MIC values ​​of silver nanoparticles and clindamycin were 16 µg/ml and 64 µg/ml, respectively. The synergy test of the combination of silver nanoparticles yielding an FIC value of 0.75. Based on the result of the study, it was concluded that the combination of silver nanoparticles and clindamycin had partial synergy properties. The Minimum bactericidal Concentration (MBC) value clindamycin alone compared in combination with silver nanoparticles 16 µg/ml reduces from 256 µg/ml to 128 µg/ml. Combinations of silver nanoparticle and clindamycin are the potential to reduce side effects and overcome resistance.
A LEI DE ACESSO À INFORMAÇÃO COMO FORMA DE CONCRETIZAÇÃO DO DIREITO À VERDADE NA JUSTIÇA TRANSICIONAL BRASILEIRA
Authors: Kalkmann Tiago
Published: February 2020

Resumo: o trabalho busca expor a relação que pode ser estabelecida entre o movimento de justiça transicional e os mecanismos de acesso à informação. A Justiça de Transição, enquanto movimento político e jurídico, encontrou no Brasil desafios à sua completa implantação. Dentre as quatro frentes principais de ação dos mecanismos transicionais, apenas as reformas institucionais (com ressalvas) e os mecanismos compensatórios foram implantados a tempo, vindo o direito à verdade a ser garantido apenas muito tempo após a queda do regime. O direito à verdade não busca substituir a narrativa oficial, mas inserir novas referências na história através de seu confronto com a memória. Os documentos do regime militar são essenciais, mas seu acesso foi bloqueado pelo governo brasileiro durante muitos anos. Apenas através de impulsos externos, foi possível a promulgação da Lei nº 12.527/2011, que modernizou o direito de acesso à informação. As mudanças trazidas pela nova lei, com as alterações das possibilidades e prazos de sigilo, aliadas à ação da Comissão de Verdade, possibilitou momento de abertura de arquivos da repressão. Este movimento possibilitou a modernização de direitos fundamentais e do direito administrativo, além de contribuir para uma aproximação do princípio da publicidade de sua feição substancial.

Este artigo descreve o contexto de comércio digital e a importância dos dados para viabilização das relações econômicas; uso das promoções comerciais como ferramentas publicitárias e coletora de dados e dos marcos regulatórios para a proteção de dados pessoais brasileiros e europeus; o potencial da Secretaria de Acompanhamento Fiscal, Energia e Loteria em contribuir na criação de valores sociais; e recentes promoções comerciais autorizadas sob o prisma da proteção de dados dos participantes; concluindo que pouquíssimo foi exigido das empresas para evitar indevido uso desses dados e que grande maioria não dispõe em seus regulamentos detalhes da utilização dos mesmos. O método empregado é o hipotético-dedutivo, com estudo de caso, levantamento de legislação e doutrina nacional e internacional. Os resultados apontam apenas três dos casos estudados mencionando superficialmente como os dados serão tratados, os demais casos se limitam a solicitar a autorização do uso de imagem e voz. O Brasil dispõe de proteção dispersa e a partir de 2020 também de específica sobre o tema proteção de dados. A Diretiva Europeia de Proteção de Dados Pessoais já opera. Se conclui que a proliferação do uso das promoções comerciais para coleta de dados, crescimento do volume de negócios digitais e utilização de novas tecnologias para a publicidade pressiona para existência de marcos legais específicos, porém demandantes dos órgãos públicos cobrando observação preventiva, estabelecendo um paradigma jurídico administrativo condutor para maior responsabilidade social corporativa e mais desenvolvimento tecnológico para proteções da economia e consumidor envolvendo dados do cidadão.
TRA PRINCIPIO DI EGUAGLIANZA E RESPONSABILITÀ: DIVERSI ITINERARI DI TUTELA DEL MINORE
Authors: Zambrano Viriginia
Published: February 2020

Scopo di questa ricerca è quello di evidenziare come il minore sia innanzitutto “persona”, rispetto alla quale occorre declinare i principi di uguaglianza e responsabilità. La metodologia utilizzata è di tipo deduttivo. Lo studio si avvale dei contributi della giurisprudenza e della dottrina sia italiana che straniera. Infine, la ricerca è qualitativa. Si intende rilevare come la tutela del minore dipenda da una serie di profili che si collegano ad una etica sociale della legalità e dei diritti umani. Il diritto ad una famiglia, alla casa di abitazione, il diritto a conoscere le proprie origini sono alcuni degli aspetti sui quali si è inteso riflettere, per dimostrare su cosa poggia la protezione del minore. Questi è un essere in formazione, sia dal punto di vista fisico che psichico, e ha bisogno di essere tutelato in quanto persona. Non si tratta di vedere solo cosa stabilisce la norma: per rendere efettiva la tutela occorrono adeguate politiche pubbliche in grado di garantire l'applicazione dei principi di uguaglianza e responsabilità, nonché etici. Sia nel campo teorico che nell'attuazione delle politiche pubbliche, occorre assicurare lo sviluppo della personalità del minore.

ABSTRACT

Watermarking in medical images is carried out to protect ownership rights and authenticity of a medical image. The embedding and extraction process was designed using Stationary wavelet transform (SWT) and Statistical Mean Manipulation (SMM) methods to convert the host image into a sparse signal and then enter the watermarking process. The watermark image is optimized using the Compressive Sensing (CS) method. The final result of this final project shows the simulation of Image Watermarking with the Bit Error Rate (BER) approaching zero and PSNR greater than 40 dB, without being given an attack. The application of the Compressive Sensing pursuit will cause the PSNR increase up to 3.5 dB and embedding capacity four times better.

Method of Moments versus Advanced Transverse Wave Approach for EM Validation of Complex Microwave and RF Applications
Authors: Ayari Mohamed , El Touati Yamen , Altowaijri Saleh
Published: February 2020

The art of benchmarking study has improved at an astonishing rate the scientific research in all areas but mainly in microwave engineering domain, and in particular, the field of microwave (MW) and radiofrequency (RF) integrated circuit design. Moreover, the fast simulation of complex MF/RF structures is considered a big challenge for the simulators, mainly in light of the continuous information and communication technology (ICT) development. In this context, the present paper sets out to present two important numerical electromagnetic (EM) methods, the method of moments (MOM) and our advanced transverse wave approach (A-TWA) for full-wave analysis of RF/MW structures. The computational complexity of these methods is evaluated. Two complex printed antennas working in the RF/MW range are selected and investigated. The EM problems that can be found in these circuits and that could not be solved analytically or by other numerical methods are discussed. The EM-validation of the studied structures using A-TWA and MOM is demonstrated and compared in the context of RF/MW applications. The obtained simulation results prove the efficiency and rapidity of our approach in comparison with the literature.
An Efficient Technique for Solving Inhomogeneous Electromagnetic Inverse Scattering Problems
Authors: Elkattan Mohamed
Published: February 2020

The electromagnetic inverse scattering approach seeks to obtain the electric characteristics of a scatterer using information about the source and the scattered data. The inverse scattering problem usually suffers from limited knowledge about the scatterer used, which makes its solution more challenging than the forward problem. This paper presents an inversion approach to estimating the unknown electric properties of a two- and three-dimensional inhomogeneous scatterer. The presented approach considers the inverse scattering problem as a global minimization problem with a meshless forward formulation for the computation of the scattered electromagnetic field. Various simulated annealing cooling schedules are applied and assessed to solve the problem, and the results of several case studies are presented for both two- and three-dimensional electromagnetic inverse scattering problems.
Choosing your own adventure: Engaging the new learning society through integrative curriculum design
Authors: Ryder Elizabeth , Ruiz Carolina , Weaver Shari , Gegear Robert
Published: February 2020

In our increasingly data-driven society, it is critical for high school students to learn to integrate computational thinking with other disciplines in solving real world problems. To address this need for the life sciences in particular, we have developed the Bio-CS Bridge, a modular computational system coupled with curriculum integrating biology and computer science. Our transdisciplinary team comprises university and high school faculty and students with expertise in biology, computer

science, and education.

Our approach engages students and teachers in scientific practices using biological data that they can collect themselves, and computational tools that they help to design and implement, to address the real-world problem of

pollinator decline.

Our modular approach to high school curriculum design provides

teachers with the educational flexibility to address national and statewide biology and computer science standards for a wide range of learner types. We are using a teacher- leader model to disseminate the Bio-CS Bridge, whose components will be freely

available online.

Online Learning in the Arab World: A Shifting Landscape
Authors: Halawa Sherif , Yacoub Shireen
Published: February 2020

This paper presents an analysis of the engagement of learners in the Arab World with Edraak, a regional online learning platform, between 2015 and 2018. Our analysis investigates the changes in demographic characteristics of registration and engagement with online courses across the 4-year period. We also investigate correlations at the country level between engagement with online learning on Edraak and several human and technology development indices of the countries. The results show gradual but substantial shifts in demographic characteristics of engagement over the 4 year period, including noticeable drops in average registrant age and a shrinkage of the gender gaps in registration. The correlations of registration and engagement with human and technology development indices show that gender gaps in 2015 were positively correlated with the Arab countries’ gender inequality indices (GII), and that the shrinkage in gender gaps over the 4 years is negatively correlated with the GII. Our results also show that penetration of online learning is negatively correlated with the countries’ Information and Communication Technology (ICT) indices, but positively correlated with the digital skills ICT sub-index. We point out possible explanations for these correlations that could be further researched in the future to inform policy makers on how certain development conditions can promote or restrain the adoption of online learning at a national level.
Inclusivity through Asynchronous Interactions that Extend Past Barriers to Education
Authors: Spackman Jonathan
Published: February 2020

This paper explores a case study of how educators reach out to and edify individuals behind barriers to educational opportunities. The scope of this paper does not address all barriers to education, but researches three: distance as a barrier that keeps a student physically distanced from the classroom, time as a barrier that forces communication to be asynchronous, and extendibility as a barrier that begs the question, “Can a teacher’s influence be satisfactorily extended through the barriers of distance and time?” Edifying, within this interpretive frame, is defined as inviting the alma mater presence, guiding the learning experience, and revealing the previously out of reach or concealed context to the learner. Through an examination of artifacts and conducting of interviews, five themes describe how one organization successfully reaches out to and edifies learners behind the barriers of distance, time, and extendibility. These themes are the significance of feedback, overcoming the burden of asynchronicity, genuine concern for the student, true to brand, and cost consciousness.
Bridging Continents - Engagement in the Classroom

STEAM Unit I Challenge - How do we break through limitations created by war?

Although this was the guiding question for our STEAM Innovation Program 2018 first Trimester unit, the real question became “How can you engage learners and compete with the reality of their lives outside of school?” The reference here is not the typical high school experience of competing with social media or the extensive time requirements of intense sports. At Greater Lawrence Technical School, the reality of our students' and families’ lives is never simple, but became increasingly difficult after the tragedy of the gas explosions in Lawrence, North Andover, Andover - 3 of our 4 sending communities. The area most seriously affected was Lawrence, which encompasses 80% of our student population. Families all throughout Lawrence were removed from their homes, many displaced for months. In this backdrop of personal uncertainty, our program began a transdisciplinary bioreactor project to make medication for Syrians. Students designed their own bioreactors from items that could be found in war-torn Syria (e.g. from bombed hospitals or factories in Damascus). Although Greater Lawrence students continued to struggle with needs for heat and hot water for months, it was this intimate knowledge of hardship that bridged these two worlds - Syria and Lawrence, MA - and the parallel experiences made the learning significant. The success of our Exhibition of Leaning from this unit underscored the importance of engaging students regardless of persisting outside hardship and connecting project-based learning to something within the context of our students lives. The experience that the students themselves lived through during our bioreactor project demanded a rewording of our unit challenge to the following:

- “How do we innovate, adapt, and change to counteract limitations?”
Educational Model for the Development of Higher Education in the Latin American Society
Authors: Santander José Antonio
Published: February 2020

The Latin American educational context contains particular features (aspects) that make the Learning - Teaching in higher education process a real challenge for the professor, the student and for the institution that makes it necessary to design a model based on four relevant lines of work. Leadership, technology, research and projects.

Lines of work that influence the gap between the expectations and needs of the community with respect to teacher productivity and competitiveness. For this reason we propose a model appropriate to the context that seeks to work in conjunction with networks and communities of professionals of the Ecosystem of innovation and entrepreneurship in addition to the main actors of educational institutions.

The model aims to achieve in educational institutions a worldwide competitive level, which allows to face the new challenges of the 4th industrial revolution that were set in the World Economic Forum in 2018. Forming competitive professionals and prepared for these new challenges with international validations of their skills, which allow us to meet the commitments and expectations with society to be generators of research, innovation and development that contributes to the growth and improvement of our communities.

Published: February 2020

This study explores experiences in the use of mobile learning (mLearning) to train Community Health Volunteers (CHVs) in Kenya. It is drawn form a PhD research on mLearning adoption among CHVs enrolled on the mHealth platform. The study population was 3081 CHVs enrolled on the project. A sample of 354 participants was obtained for the survey. Questionnaires, key informant interviews and focus group discussions were triangulated during data collection. The findings show that mLearning was adopted across divergent learner characteristics. Further, mLearning presented opportunities such as a collaborative learning environment, accessibility, portability, and simplicity. The challenges included a limited depth of content, limited storage and battery life. This study concludes that mLearning can be used among diverse learners as long as effective support services are provided. The study recommends design of learner friendly mLearning platforms to enhance adoption. The study also recommends that mLearning is best situated in blended learning environments in order overcome some of the challenges experienced when mLearning is the only mode of delivery.
