Abstract
We report the results of the first state-of-the-art numerical simulations of coronal mass ejections (CMEs) taking place in realistic magnetic field configurations of moderately active M-dwarf stars. Our analysis indicates that a clear, novel, and observable, coronal response is generated due to the collapse of the eruption and its eventual release into the stellar wind. Escaping CME events, weakly suppressed by the large-scale field, induce a flare-like signature in the emission from coronal material at different temperatures due to compression and associated heating. Such flare-like profiles display a distinctive temporal evolution in their Doppler shift signal (from red to blue), as the eruption first collapses toward the star and then perturbs the ambient magnetized plasma on its way outwards. For stellar fields providing partial confinement, CME fragmentation takes place, leading to rise and fall flow patterns which resemble the solar coronal rain cycle. In strongly suppressed events, the response is better described as a gradual brightening, in which the failed CME is deposited in the form of a coronal rain cloud leading to a much slower rise in the ambient high-energy flux by relatively small factors (∼2–3). In all the considered cases (escaping/confined) a fractional decrease in the emission from midrange coronal temperature plasma occurs, similar to the coronal dimming events observed on the Sun. Detection of the observational signatures of these CME-induced features requires a sensitive next generation X-ray space telescope.
Evidence of Nonluminous Matter in the Center of M62

Published: October 2019

Abstract
Theoretical models suggest that intermediate-mass black holes (IMBHs) may form and reside in the centers of globular clusters. IMBHs are still elusive to observations, but the accelerations of pulsars may bring along a unique fingerprint of their presence. In this work, we focus on the pulsars in the globular cluster M62. Using the new distance of M62 obtained from Gaia observations, we find that the measured pulsars’ accelerations suggest a central excess of mass in the range [1200, 6000] M
☉, corresponding to [0.2, 1]% of the current total mass of the cluster. Our analysis cannot unambiguously discriminate between an IMBH or a system of stellar mass dark remnants of comparable total mass.

Authors: Abrahão Pérsio Vitor de Sena , Oliveiva Edson Aparecida de Araújo Querido 
Published: October 2019

Os projetos estão presentes no dia a dia de praticamente todas as organizações, com investimentos que representa quase um terço do PIB mundial. Muitas empresas têm utilizado os modelos de maturidade para avaliar a capacidade de gestão de seus projetos e estabelecer ações de melhoria. O Modelo Prado MMGP tem sido muito utilizado no Brasil para a avaliação de departamentos isolados. Ele, assim com a maioria deles, se baseia unicamente em respostas a um questionário, isso pode prejudicar a acurácia dos resultados em situações onde há uma quantidade muito reduzida de pessoas qualificadas para respondê-lo. Este estudo tem como objetivo verificar a aplicabilidade da análise dos documentos relacionados ao gerenciamento de projetos, como instrumento complementar ao método Prado-MMGP para ampliar as discussões e melhorar a avaliação do nível de maturidade. Para isso, optou-se pela realização de um estudo de caso único do tipo descritivo-exploratório em um departamento de desenvolvimento de novos produtos em uma empresa de base tecnológica de médio porte. Com a utilização de critérios semelhantes ao modelo MMGP pôde-se calcular os índices de aderência aos níveis e dimensões desse modelo, que produziram resultados comparáveis aos da aplicação do questionário e possibilitou analisar os resultados por diferentes fontes de evidência. Assim, pôde-se verificar que a utilização das evidências documentais pode trazer informações adicionais e contribuir para melhorar a acurácia na avaliação do nível de maturidade. Porém, sua aplicação fica restrita aos casos onde o pesquisador tenha acesso aos documentos dos projetos.

Published: October 2019

O presente artigo buscar identificar como as variáveis de desempenho (explicativas), representadas pelo financiamento público, gastos com P&D das empresas e capital humano influenciam o processo de inovação, representado pelo mecanismo de patenteamento (variável dependente), e analisar essas variáveis na perspectiva regional. Para realização do estudo, foi utilizado o método econométrico de regressão com dados em painel, considerando os últimos dez anos, distribuídos por triênio (2005, 2008, 2011 e 2014) e por região brasileira. Para este estudo, foram analisados dados da Pesquisa de Inovação (PINTEC), nas edições 2005, 2008, 2011, e 2014, dados do Instituto Nacional da Propriedade Industrial (INPI), do Sistema de Informações Georeferenciadas (GEOCAPES), da FINEP e do BNDES, no período de 2005 a 2014. Quanto aos resultados encontrados apesar da presença de outliers, ter gerado algumas distorções na interpretação dos testes estatísticos aplicados às amostras, pode-se inferir que as variáveis de desempenho elencadas no modelo explicam em 57% o número de depósitos de patentes no Brasil, confirmando a hipótese adotada. PALAVRAS-CHAVE: Patentes. Financiamento Público. Dados em Painel. Brasil.

BACKGROUND AND OBJECTIVE:
To evaluate the flow characteristics and textural properties of choriocapillaris (CC) on optical coherence tomography angiography in eyes with resolved inflammatory choriocapillaropathies and Vogt-Koyanagi-Harada (VKH) disease.

PATIENTS AND METHODS:
A cohort of eyes with healed acute posterior multifocal placoid pigment epitheliopathy (APMPPE), serpiginous choroiditis (SC), and VKH disease were included. A 3 mm × 3 mm OCT angiogram of CC was acquired and graded for flow characteristics and textural properties.

RESULTS:
This study included 16 patients. Texture was heterogeneous in all eyes in the SC and VKH groups, and in four eyes (40%) in the APMPPE group. Most of the eyes with VKH disease had severe low flow, whereas most of the SC and APMPPE eyes demonstrated mild low flow. Heal duration had a strong negative correlation with severity of CC low flow and a weak, statistically nonsignificant correlation with texture heterogeneity.

CONCLUSION:
Despite the resolution of active inflammation, partial CC hypoperfusion and texture disruptions persist for longer durations and may resolve in a time dependent manner.

O papel da formulação de questões durante a leitura compartilhada de livros na educação infantil
Authors: Pereira Aline E. , Gabriel Rosângela , Justice Laura M. 
Published: October 2019

The shared reading of books is one of the activities that most contributes to the development of young children's language (JUSTICE; SOFKA, 2010; SÉNÉCHAL, 2015; EVANS; SAINT-AUBIN, 2005; SÉNÉCHAL; LEFEVRE, 2002) and has effects in the acquisition of the written language registers (BUS et al., 1995). However, the effects of this contribution depend on how the adult interacts and encourages the child's participation in the discussion and reflection beyond the text. Young children who actively participate in adult-led shared reading of books, which interact with them through questions, word-labeling, and referents, have greater gains in vocabulary than children who passively hear the book reading (SÉNÉCHAL et al., 1995). In addition, the use of questions plays a key role in directing attention and maintaining the child's participation in the activity of shared reading. The purpose of this study is to (1) determine how often preschool teachers ask questions during shared reading of books with their students, and (2) identify the types of questions that teachers asked related to basic vs. complex questions. A total of nine teachers and their students aged 3 to 5 years, from a city in the interior of Rio Grande do Sul, Brazil, participated in the study. Two shared reading sessions of each teacher (n = 18) were recorded on video, transcribed and coded using an adapted version of the Systematic Assessment of Book Reading-Transcript Coding Version 2.1 (ZUCKER et al., 2017). The results show that during the eighteen shared reading sessions, teachers compiled a total of 329 questions, classified into two categories: basic questions and complex questions. From the total, the basic ones had a higher frequency (n = 285) and complex questions were formulated less frequently (n = 44). The results of this research are in line with other studies (PENTIMONTI et al., 2018; BECK; MCKEOWN, 2001; GIROLAMETTO et al., 2000) that show that teachers usually ask basic questions more frequently when compared to complex questions. Therefore, we emphasize the importance of call teachers attention to the value of shared reading, mediated by an interaction that favors the formulation of questions, seeking to expand the proportion of complex questions, given the influence that this type of activity has on the cognitive and linguistic development of children.
Leitura em voz alta: variação linguística e o sucesso na aprendizagem inicial da leitura
Authors: Freitag Raquel Meister Ko , Sá José Júnior De Santana 
Published: October 2019

In an interface between psycholinguistics and sociolinguistics, considering stylistic monitoring (speech à oral activities à reading aloud) and the necessary conditions for early literacy, this paper presents the reading profiles of 3rd grade students from elementary school and relates them to performance on a reading comprehension test and to the occurrence of variable features of speech in reading aloud. The results show that the reading aloud which presents variable features of speech cannot be considered “inaccurate”; instead, these features occurred only in proficient and word-to-word types of reading, and only by students who reached higher levels on the test.
The effects of cognitive training on executive functions and reading in typically-developing children with varied socioeconomic status in Brazil
Authors: Weissheimer Janaina , Fujii Renata Callipo , Souza Juliana Geizy Marques 
Published: October 2019

Recent findings show that children from low-socioeconomic status (SES) tend to have reduced performance on several tasks involving working memory, attention and executive control. In addition, researchers argue for the effectiveness of training of these same cognitive skills as a way to ameliorate children’s EF skills as well as scholastic outcomes. To investigate possible training effects and to study the impact of SES on scholastic achievement in Brazilian children, we trained 61 children for 5-7 weeks and compared their performance with that of 60 age-matched peers on measures of executive functions and reading. Our results demonstrate a general effect of SES for the dependent variables. Furthermore, our findings demonstrate a positive near transfer effect on a working memory and a selective attention test and a far transfer effect on the words and pseudowords reading measure.

Procedural and Institutional Backing of Transparency in Algorithmic Processing of Rights
Authors: Polčák Radim 
Published: October 2019

Efficient enforcement of legal substance requires proper procedures and capable institutions. In that respect, law is now being challenged by the emergence of automated systems that autonomously decide about matters concerning rights. The neuralgic point in enforcement of legal compliance of such systems, namely with regards to possible discrimination, is transparency. Currently, there exists, at least in the EU, particular individual right to know the logic of respective algorithms. The comment tries to narrow down the issue of actual enforceability of that right by investigating its basic procedural and institutional aspects.
Consequences of the Use of Personalization Algorithms in Shaping an Offer – A Private Law Perspective
Authors: Południak-Gierz Katarzyna 
Published: October 2019

Personalization mechanisms in consumer e-commerce allow for the adjustment of the time, form and manner of contact, the way of concluding the contract and the availability and content of the offer. Subsequently concluded agreements can be seen as a new phase of development of the consumer transaction model – secondary individualization replaces standardization. The possibility of concluding contracts on a massive scale is retained, but with added granularity and flexibility that mimic the individualisation of transactions. Special provisions for personalized contracts are missing on the EU level and within the Polish legal system.The starting point is an analysis of the reaction of the traditional private instruments of Polish law towards the personalization of offers – case law and doctrinal approach towards the concept of a standard contract and an individually negotiated one are examined. Next, the pre-contractual stage is investigated – the personalization process is explored from the perspective of unfair practices regulation, and the legal basis for the personalization process in the context of the GDPR is discussed. While Polish national law focuses on combating the undesired results of personalization, the EU initiatives aim at granting ex-ante protection. The mechanism in directive 2005/29/EC is being supplemented with an information protection mechanism (consent requirement). The limitations of this model are identified and some alternative solutions are proposed.
Juridical Status of So-called Smart Contracts against the Background of the Polish Legal Framework
Authors: Kaczorowska Bogna 
Published: October 2019

Among substantial advancements challenging contemporary contract law special attention is given to autonomous, cryptographic solutions based on decentralised infrastructure provided by blockchain technology, intended to execute transactions automatically, designated as smart contracts. The need for comprehensive research on legal implications of practical implementation of this technological innovation is triggered particularly by the prognostications declaring it a valid alternative to hitherto contract law framework that is expected to be ultimately replaced by algorithmic mechanisms underpinning smart contracts.A relevant assessment of the impact smart contracts are presumed to have on the contract law domain requires a thorough analysis of their juridical status. The specificity of the category of smart contracts raises doubts whether they comply with the definition criteria inherent to contract law terminology. Additionally, it is of material importance to determine the function smart contracts can perform in the sphere of contractual practice and to confront it with the role and axiology of contract law.The article aims at analysing the peculiarities of smart contracts from the perspective of the Polish private law system with account being also taken of current development tendencies concerning the concept of contract.
In the Procedural Surroundings of Consumer Protection: Online Dispute Resolution, the Adversarial Principle, and Tendencies toward Settlement
Authors: Björling Erik 
Published: October 2019

The article builds on a pluralistic perspective on law and the understanding that legal research must take into account the procedural and institutional landscape where legal rights are enforced. In relation to online dispute resolution (ODR), two procedural mechanisms, namely the adversarial principle and the tendency toward settlements, are studied and discussed. The adversarial principle (argued to be integral to most ODR procedures) and tendencies toward settlements (also argued to be integral to most ODR procedures) are considered in relation to the overarching (and possibly contradictory) objectives of protecting individual consumer rights and the interest of increasing economic efficiency within the EU’s internal market.
Blockchain-based Land Registration: Possibilities and Challenges
Authors: Kaczorowska Maria 
Published: October 2019

In recent decades land registration systems operating in Europe and worldwide have been subject to modernisation processes consisting in implementation of information and communication technologies. Such reforms have gradually led to facilitating access to land information, improving effectiveness of land registration proceedings and even introducing possibilities to dispose of the ownership of land electronically by developing electronic conveyancing mechanisms. Another innovative concept much discussed nowadays is the application of blockchain technology in the land registration sector. This solution is currently being tested in a number of countries.Distributed ledger technology underlying blockchain is expected to revolutionise land registration by offering a secure architecture to store land transactions with the use of cryptographic protocol. This shall bring advantages of increased trust and processing efficiency as well as reduction of costs. However, the above idea raises concerns given that, under the assumptions of the “original” blockchain model, transactions are irreversible and are carried out without intermediaries, which means the lack of any external control and independent verification of the transactions to be recorded.The article examines potential benefits and risks of automatisation of land transactions as well as practical experiences of selected countries in implementing blockchain in the area of land registration. On this basis, an assessment will be made as to whether blockchain-based registration could indeed replace the existing methodology of registering rights to land.
