Authors: Suarez-Lledo Victor , Alvarez-Galvez Javier
Published: January 2022

BACKGROUND

Social media has changed the way we live and communicate. These tools are an unprecedented instrument that may lead to great opportunities for improving many aspects of our lives, including health promotion and disease prevention. However, social media also presents a dark side that is not always so evident as its possible benefits. In fact, social media has also opened the door to new social and health risks that are linked to health misinformation.

OBJECTIVE

This work aims to study the role of social media bots during the COVID-19 outbreak.

METHODS

We use Twitter Stream API to collect tweets about Covid-19 during the early outbreak. Then, we use Botometer to obtain the probability that each account is a bot or not. We use bot classification along with topic modeling techniques to understand the Twitter conversation. Finally, we compare the sentiment associated with the tweets regarding the source of the tweet.

RESULTS

With respect to the topics of conversation, we found notable differences between the different accounts. The content associated with no-bots accounts is associated with the evolution of the pandemic, support, and advice. On the other hand, in the case of self-declared bots, the content is mostly news. That is the existence of diagnostic tests, the evolution of the pandemic, scientific findings. Finally, in the case of bots, the content is mostly political. Above all, a general tone of criticism and disagreement predominates. In relation to sentiment analysis, the biggest differences are associated with the tone of the conversation. Conversation in the case of self-declared bots tends to be neutral. While the conversation of normal users scores positively. In contrast, bots tend to score negatively.

CONCLUSIONS

By classifying the accounts according to the probability of being bots together with topic modeling we were able to segment the Twitter conversation about Covid. The tone of messages written by non-bots accounts tends to be more positive than the former. On the contrary, the tone of non-declared bots is always more negative than the tone of self-declared ones.

Published: January 2022

Background: Coronary collateral circulation (CCC) is an adaptive response to chronic myocardial ischemia. Patients with coronary stenosis develop varying degrees of collateral. Levels of inflammatory cells were suggested as potential determinants of collateral development. Neutrophil to lymphocyte (N/L) ratio has been proposed as a prognostic marker to determine systemic inflammatory response and the development of CCC. Our aim was to determine the relationship between N/L ratio and development of CCC in patients with coronary artery disease (CAD) with multivessel disease.Method:A total of 151 patients with multivessel disease were included in this study. Coronary collateral grades were classified according to Rentrop collateral grades as either poorly developed CCC (Rentrop grade 0-1) or well developed CCC (Rentrop grades 2-3). Factors significant at the p≤0.25 in the bivariate models were put into multiple logistic regressions. The receiver–operating characteristic (ROC) analysis were performed to determine the cutoff value of NLR in predicting poor CCC.Result: Of the 151 CAD patients in this study, 76 patients had poorly developed CCC and 75 patients had well developed CCC. Poorly developed CCC had significantly higher N/L ratio than well developed CCC (2.25±1.189 vs. 3.03±1.527, p <0.001). Logistic regression analysis showed that N/L ratio (OR0.756; CI 95% 0.587 – 0.974, p 0.031) was independent predictor of poorly developed CCC. The ROC analysis provided a cut-off value of 1.99 (AUC 0.72, sensitivity 78.9%, specificity 52%) for N/L ratio to predict poorly developed CCC.Conclusion: Higher neutrophil to lymphocyte ratio was useful in predicting poor coronary collateral circulation in stable coronary heart disease with multivessel disease. Neutrophil to lymphocyte ratio >1.99 was independently associated with impairment in coronary collateralization. This value had a sensitivity of 78.9% and specificity of 52%.

Authors: Widodo Setiawan , Mumpuni Hasanah , Taufiq Nahar
Published: January 2022

Background: Coronary heart disease (CHD) is a problem that contributes to morbidity and mortality. Acute myocardial infarction with ST-Segment Elevation Myocardial Infarction (STEMI) is the most common manifestation of CHD. Cardiac muscle damage caused by STEMI is dynamic. The longer coronary is occluded, the area of ​​infarction will be greater than cause biomechanical changes in the myocardium. Speckle Tracking Echocardiography (STE) through a longitudinal strain parameter is a technique of assessing myocardial deformation and predicting the infarct area immediately after reperfusion therapy.

Method: This study was an analytic observational study with a cross-sectional method. Subjects were STEMI patients who were successfully reperfused and fulfilled the inclusion and exclusion criteria. Transthoracic echocardiography was performed within 12 hours after reperfusion. Strain analysis was done offline at the work station. A normality test was performed to determine the type of correlation test used. The influence of confounding factors was analyzed by bivariate and multivariate. A value of p <0.05 was said to be statistically significant.

Results: There were 43 subjects, ischemia time and global longitudinal starin (GLS) ​​were obtained. A normality test using Shapiro Wilk revealed that data distribution of the two variables was abnormal. The Spearman correlation test was used to assess the relationship between the two variables and found a negative correlation between the time of ischemia and GLS (r = -0.546; p = 0.000). Bivariate and multivariate analyses were performed to assess the influence of confounding factors. From the multivariate test, it was found that ischemia time was an independent factor influencing GLS value (p = 0.002).

Conclusion: There is a negative correlation between ischemia time and left ventricular GLS in STEMI patients who were successfully reperfused (r = -0.546; p = 0.000).

Published: January 2022

AbstractBackground: Patients underwent Coronary Artery Bypass Surgery are at risk of developing post-operative complications that affect length of stay, re-hospitalization and increase in mortality rate. Impaired functional capacity is associated with poor outcomes in patients after CABG. The Six Minute Walk Test (6MWT) is generally used to evaluate functional capacity before cardiac rehabilitation and to prescribe the intensity of exercise training. The six minute walk test (6MWT) is a simple test and has been used in heart failure patients to assess exercise tolerance, the effects of therapy and prognosis. This study is to investigate the relationship between the distance of 6MWTwith re- hospitalization and mortality rate in post coronary artery bypass surgery patients.Method: This is a retrospective cohort study conducted at Cardiac Centre of Adam Malik Hospital. Subjects of the study consists of 104 patients underwent coronary bypass surgery between January 2019 until February 2020. 6MWT is performed before the patient discharge. Rates of re-hospitalisation and mortality were observed during 3 months of follow-up. The distance walk during 6MWT was compare to rate of rehospitalization and cardiac mortality. Result: Total of 104 patients (91 males, mean age 57,4±5,7 years). Six patients died (5,8%) of cardiovascular cause and 18 (17,3%) were rehospitalized. Significant relationship was found between the distance of 6MWT and incidence of mortality and re-hospitalization (p <0.001). Patients with 6MWT <250 meters had a higher risk of re-hospital compared to those with 6MWT >250 meters with RR 16.74 (95% CI: 2.53-110.78) and p = 0.008. Conclusion: The six minute walk test (6MWT) is a predictor of re-hospitalization in patients post CABG. Patients who walked in shorter distance group <250 meters would increase risk of re-hospitalization rate 16.74 greater than patients with distances >250 meters.

Authors: Maharani Erika , Mumpuni Hasanah , Hidayati Fera
Published: January 2022

Background: Rheumatic mitral stenosis is the most common valvular abnormalities found in developing countries. Mortality risk in those populations was poorly investigated. In addition, hemodynamic, morphological, and mechanical factors that influence or predict outcome of rheumatic mitral stenosis have not been identified.

Aims: To determine predictive factors affecting outcome in rheumatic mitral stenosis patients.

Method: This retrospective cohort study was conducted at the National General Hospital Dr. Sardjito, Yogyakarta, Indonesia. The study recruited patients from the Valvular Heart Disease Registry from May 2014 to November 2020. New York Heart Association (NYHA) functional classification, invasive or surgical treatment, and incidence of death were recorded. The baseline rhythm from electrocardiography (ECG) was categorized as sinus rhythm and atrial fibrillation or atrial flutter. Based on the findings of trans thoracal echocardiography (TTE), subjects who had moderate to severe pure rheumatic mitral stenosis (or followed by mitral regurgitation and / or less significant tricuspid regurgitation as a natural history) and subjects with rheumatic mitral stenosis with a combination of other heart valve problems (of which severity more significantly) classified as groups I and II. The mitral valve area (MVA), mitral valve gradient (MVG), left atrial diameter (LA), and mean pulmonary artery pressure (mPAP) were then analyzed.

Results: A total of 477 patients (mean age 44.08 ± 10.93 years; 71.5% female) were enrolled in this study. There were 61 deaths during the median follow up of 393 days of which 35 deaths occurred in group I and 26 deaths occurred in group II. Kaplan Meier curve shows the 1 year survival rate is higher in group I than group II which is 92.5% and 92%, respectively. Bivariate followed by multivariate analysis showed MVG and mPAP were predictive risk factors for mortality in group I with p = 0.020 and p = 0.021. MVG parameter values evaluated from echocardiography with a cut-off of more than 10 mmHg and mPAP parameters with a cut-off of more than 50 mmHg were independent predictive risk factors for mortality. Thus, patients were at higher risk of death if MVG > 10 mmHg and mPAP > 50 mmHg

Conclusion: One year survival rate in group I was higher than group II. MVG and mPAP were risk factors for predicting mortality in group I.

Published: January 2022

Abstract: In MIMO millimeter-wave (mmWave) systems, while the hybrid digital/analog precoding structure provides the ability to increase the reach rate, it also faces the challenge of reducing the channel time limit due to the large number of horns on both sides of the Tx / Rx. . In this paper, channel measurement is done by searching with multiple beams, and a new hierarchical multi-beam search system is proposed, using a pre-designed analog codebook. Performance tests show that, compared to a highperformance system, the proposed system not only achieves a high level of success in getting multiple beams under normal system settings but also significantly reduces channel estimation time Keywords: Massive MIMO, Channel Estimation, precoding

Authors: Badiev Igor V.
Published: January 2022

The problem of aggression and violence in the educational space is currently quite serious. Illustrative examples of it are numerous publications in the media about acts of aggression exhibited by students against their peers and teachers, about the use of violence by teachers against their students, acute conflicts between the parents of students, sometimes leading to tragic consequences. In this regard, the works devoted to the problem of the psychological safety of the educational environment become very important. The purpose of our research is to identify the factors of psychological safety of the educational environment in the context of the aggressiveness of the participants in educational relations. The study involved 15 292 respondents, including 945 teachers, 6478 parents and 7869 students of grades 7-11 from 34 schools in Ulan-Ude. The following psychodiagnostic techniques were used: Cook - Medley Hostility Scale (CMHS); Questionnaire of Legitimized Aggression by S.N. Enikolopov and N.P. Tsibulsky; Bass - Perry Aggressiveness Questionnaire BPAQ (LA-44) in Russian adaptation by S.N. Enikolopov and N.P. Tsibulsky; questionnaire for students, teachers and parents Psychological diagnostics of the safety of the educational environment at school by I.A. Baeva. The empirical data obtained were subjected to correlation and factor analysis. As a result of the study, the following conclusions were formulated: (1) the psychological safety of students is associated with the peculiarities of the relationships between the teachers and students, between the parents of students and the school, between the parents and other students, between the parents and their children in the context of school education; (2) aggressiveness of students is associated with the level of aggression of their teachers and is not closely related to the level of aggression of their parents; (3) there is an inverse relationship between the aggressiveness of students and their sense of security in relationships with their teachers; (4) aggressiveness of teachers is associated with their satisfaction with the school. There are five areas of relationships that need to be taken into account when designing a safe educational environment: (1) the relationship between parents and students at school; (2) the relationships among teachers and accepted rules of conduct at school; (3) the relationships between teachers and students; (4) family satisfaction with school; (5) teachers satisfaction with the school.

Published: January 2022

The topic on diagnosing intercultural adaptation and psychological acculturation to a new socio-cultural environment is relevant in connection with the processes of globalization and, in particular, with the growth of academic mobility in education. Research on this problem are especially relevant for Russian science due to the lack of acculturation scales, which are widely represented in Western and international psychology. In 2019, a research team led by Professor A. Ardila developed the Russian-language Acculturation Scale for Russia (ASR), which was validated on a sample of international university students from 71 countries of the world. The aim of the present study was to adapt the ASR for the Chinese students studying in Russian universities. Chinese students are the largest group of international students from far abroad studying at Russian universities, while many of them experience significant difficulties in adapting to a new socio-cultural environment, as well as in learning the Russian language. In total, the study involved 213 Chinese students (59% - female) studying at Russian universities, of which 93 students (58% - female) completed the Russian-language version of the ASR, and 118 students (61% - female) completed the Chinese version of the ASR, which was designed using the back translation. Both ASR versions were psychometrically tested using Cronbachs and MacDonalds coefficients, as well as bifactorial analysis. The methods of descriptive statistics and the Wilcoxon W-test were used to compare the Russian-language and Chinese versions of the ASR. The normalization was carried out by means of non-linear percentile normalization (stanines). As a result, a high consistency of the Russian-language and Chinese versions of the ASR and their equivalence with each other were shown. Both versions can be used to assess the level of acculturation of Chinese students to Russia, while the Chinese version is recommended for the Chinese students who have been living in Russia for less than 1-1.5 years and/or have a poor Russian proficiency.

Using the Phonological Approach to Describe the Vocal System of the Russian Language in the Context of Russian-Spanish Language Contact
Authors: Bondareva Veronika V.
Published: January 2022

The article is devoted to the description of the vocal systems of different languages, considering the functional approach, based on the objective linguistic reality. Today the traditional approach used by research scientists is gradually losing the ability to identify effective models of the phonetic-phonological system of the language, which significantly affects the productivity and research results. The rapid development of new directions of science, the evolution of the language system and all its sublevels indicates the need to adjust the traditional principles of describing phonetic-phonological systems of different languages and imposes special requirements on the relevance, productivity, adequacy and compliance of such descriptions with objective reality. The article analyzes the system of vowels from a phonological point of view - a general classification of vowels through the prism of phonological systematics of meaningful oppositions - considering the articulatory base of the language and the modern orthoepic norm, their changes in the flow of speech, an inextricable connection with consonantism and the prosodic organization of the word. This system is more productive and relevant for solving the problems of modern linguistics. The approbation of the vocal system of the Russian language, obtained within the framework of the corrected approach to the description of systems, is carried out in conditions of language contact, since the problems of language contact are interconnected with the main tasks of the theory of language in the framework of the comparative historical description and comparison of languages. Phonetic interference, together with a foreign accent, is a consequence of the contact between the native language and the target language. Phonetic interference, being an integral part of linguistic contact, causes a violation of the sound side of the language of foreigners. After analyzing the descriptions of the vocal systems of the Spanish and Russian languages, made within the framework of the adjusted functional approach, it is possible to highlight the main features of the Spanish accent in the pronunciation of Russian vowel sounds, and the analysis of the practical material confirms all the selected features and demonstrates the high efficiency of the above approach. The results of this work can be used in various theoretical courses, as well as to create systems for automatic synthesis and speech recognition.

O contexto de aplicação em terra de enunciados e teses: implicações na relação entre as filiações biológica e afetiva
Authors: Marques Elmer Da Silva , Sulzbach Juliane Gloria
Published: January 2022

O presente artigo tem por objeto a análise da decisão proferida pelo Superior Tribunal de Justiça (STJ) no Recurso Especial nº 1.784.726/SP. No julgamento, o STJ reafirmou entendimento de que não há, em tese, preponderância da filiação socioafetiva sobre a filiação biológica. A prevalência de uma sobre a outra ou a possibilidade de coexistência de ambas depende do caso concreto. Não se pode falar na existência de uma “preponderância da filiação socioafetiva sobre a filiação biológica”.  A análise é feita tendo como objetivo demonstrar como os textos jurídicos descontextualizados na prática jurídica brasileira influenciam na tomada de decisões posteriores, prejudicando o sistema de precedentes judiciais. A utilização de “teses”, ementas e enunciados abstratos e desconectados dos fatos que fornecem um contexto de aplicação levam a uma série de problemas. Este complexo de aplicações incorretas que condicionam o resultado deve ser afastado, fundada na análise do quadro fático como condição sine qua non para compreensão e interpretação-aplicação dos textos normativos.
Demandas Políticas e Direitos Fundamentais: as ambivalências do pluralismo no Estado Democrático de Direito
Authors: Almeida Leonardo Monteiro Crespo de
Published: January 2022

O presente artigo busca examinar de que maneira os direitos fundamentais podem ser ferramentas importantes na consolidação jurídica das demandas políticas dos grupos minoritários no contexto das democracias pluralistas. A pesquisa recorre à teoria política de William E. Connolly com o propósito de abordar os direitos fundamentais de uma maneira que os deixe abertos a sucessivas apropriações e redefinições decorrentes dos conflitos políticos. Para além de suportes institucionais que amparam as pretensões políticas dos atores políticos, os direitos fundamentais surgem como elementos que contribuem para uma maior agregação entre demandas distintas, porém conexas. Em última instância, a pesquisa investiga o lugar dos direitos fundamentais no fortalecimento de um imaginário democrático aberto e tolerante.
Política de cookies e a “crise do consentimento”: Lei Geral de Proteção de Dados e a autodeterminação informativa
Authors: Tobbin Raissa Arantes , Cardin Valéria Silva Galdino
Published: January 2022

O artigo tem por objetivo analisar a política de cookies no ambiente virtual nos termos da Lei Geral de Proteção de Dados, com base no direito à privacidade e na autodeterminação informativa. Para tanto, a pesquisa utilizou o método hipotético-dedutivo, fundamentado em revisão bibliográfica. Como resultado, verificou-se que a atual política de cookies ainda está muito longe de proteger os dados pessoais do usuário, especialmente porque os termos de uso dos aplicativos e de páginas acessadas por meio da Internet dificultam ao cidadão comum a compreensão acerca de como estes poderão ser utilizados futuramente pelo Estado e por empresas privadas no âmbito da monetização de dados propiciada pelo capitalismo de vigilância, contexto que evidencia uma “crise do consentimento” e a necessidade de proteção da autodeterminação informativa, tendo em vista a relação assimétrica entre os usuários e os agentes de tratamento de dados.

The effect of management practice on performance: The moderating role of ownership
Authors: Rieg Robert , Ulrich Patrick
Published: January 2022

While scholars agree that ownership matters for firm performance in general, the detailed effects are still debated. We argue that ownership impacts firm performance not only directly but also through implementing different levels of management practice that impact firm performance too. We show that interactions between ownership and management practice have positive and negative effects on firm performance depending on how different owners can exploit the benefits of management practices or not. In that sense, ownership moderates the effect of management practices on performance
Financial accounting manipulations and bankruptcy likelihood: A study of Nordic banks
Authors: Hundal Shab , Eskola Anne
Published: January 2022

The phenomena of accounting manipulations and bankruptcy likelihood have always been a topic of interest among researchers. The key objective of the current study is to examine the impact of fraudulent accounting practices on the likelihood of bankruptcy, and the performance of firms. Beneish M-score model and Jones model have been applied to evaluate earnings quality, whereas the Altman Z-score model has been used to analyze the level of financial distress. Based on the analysis of secondary data collected from 33 Nordic banks for the period 2011–2018, the findings disclose that Z-score of most of the sample banks has been found to be relatively high thus representing their high level of financial health. The study does not rule out potential earnings management measures applied by the sample banks. Furthermore, earnings manipulations increase the bankruptcy likelihood, especially in case of larger banks. The financial data manipulation practices artificially enhance the financial performance of banks, however, in a broad perspective; such manipulations can trigger potential financial distress
Cryptocurrency: Is it becoming a reality for Albania?
Authors: Nasto Kostandin , Sulillari Junada
Published: January 2022

The aim of this study is to realize an analysis of cryptocurrencies in Albania. Cryptocurrencies have experienced tremendous changes in the last years, and have often been the subject of debates. Albania is one of the countries in which seems really difficult to have the opportunity of using cryptocurrencies as a payment tool, or as an investment alternative. Throughout this investigation, we will treat some of the main difficulties and challenges of the cryptocurrency market in Albania. As the study reveals, it seems that it has not been easy for Albanian investors to use cryptocurrency as an investment alternative, or use cryptocurrency as a payment tool. Anyway, what we can emphasize is the fact that we can see some positive steps in this direction. Even though it seems a slow process, the removal of some legal restrictions related to cryptocurrencies reflects the “break” of the “walls” that were serving as a barrier for them in Albania. Only the future can show this, so the only thing that we can do is to wait for it
