Assessing the Role of Social Bots During the COVID-19 Pandemic: Infodemic, Disagreement, and Criticism
Authors: Suarez-Lledo Victor , Alvarez-Galvez Javier 
Published: May 2022

BackgroundSocial media has changed the way we live and communicate, as well as offering unprecedented opportunities to improve many aspects of our lives, including health promotion and disease prevention. However, there is also a darker side to social media that is not always as 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.ObjectiveThis study aimed to study the role of social media bots during the COVID-19 outbreak.MethodsThe Twitter streaming API was used to collect tweets regarding COVID-19 during the early stages of the outbreak. The Botometer tool was then used to obtain the likelihood of whether each account is a bot or not. Bot classification and topic-modeling techniques were used to interpret the Twitter conversation. Finally, the sentiment associated with the tweets was compared depending on the source of the tweet.ResultsRegarding the conversation topics, there were notable differences between the different accounts. The content of nonbot accounts was associated with the evolution of the pandemic, support, and advice. On the other hand, in the case of self-declared bots, the content consisted mainly of news, such as the existence of diagnostic tests, the evolution of the pandemic, and scientific findings. Finally, in the case of bots, the content was mostly political. Above all, there was a general overriding tone of criticism and disagreement. In relation to the sentiment analysis, the main differences were associated with the tone of the conversation. In the case of self-declared bots, this tended to be neutral, whereas the conversation of normal users scored positively. In contrast, bots tended to score negatively.ConclusionsBy classifying the accounts according to their likelihood of being bots and performing topic modeling, we were able to segment the Twitter conversation regarding COVID-19. Bot accounts tended to criticize the measures imposed to curb the pandemic, express disagreement with politicians, or question the veracity of the information shared on social media.
Acoustic and Linguistic Features of Impromptu Speech and Their Association With Anxiety: Validation Study
Authors: Teferra Bazen Gashaw , Borwein Sophie , DeSouza Danielle D , Simpson William , Rheault Ludovic , Rose Jonathan 
Published: May 2022

Background
The measurement and monitoring of generalized anxiety disorder requires frequent interaction with psychiatrists or psychologists. Access to mental health professionals is often difficult because of high costs or insufficient availability. The ability to assess generalized anxiety disorder passively and at frequent intervals could be a useful complement to conventional treatment and help with relapse monitoring. Prior work suggests that higher anxiety levels are associated with features of human speech. As such, monitoring speech using personal smartphones or other wearable devices may be a means to achieve passive anxiety monitoring.

Objective
This study aims to validate the association of previously suggested acoustic and linguistic features of speech with anxiety severity.

Methods
A large number of participants (n=2000) were recruited and participated in a single web-based study session. Participants completed the Generalized Anxiety Disorder 7-item scale assessment and provided an impromptu speech sample in response to a modified version of the Trier Social Stress Test. Acoustic and linguistic speech features were a priori selected based on the existing speech and anxiety literature, along with related features. Associations between speech features and anxiety levels were assessed using age and personal income as covariates.

Results
Word count and speaking duration were negatively correlated with anxiety scores (r=–0.12; P<.001), indicating that participants with higher anxiety scores spoke less. Several acoustic features were also significantly (P<.05) associated with anxiety, including the mel-frequency cepstral coefficients, linear prediction cepstral coefficients, shimmer, fundamental frequency, and first formant. In contrast to previous literature, second and third formant, jitter, and zero crossing rate for the z score of the power spectral density acoustic features were not significantly associated with anxiety. Linguistic features, including negative-emotion words, were also associated with anxiety (r=0.10; P<.001). In addition, some linguistic relationships were sex dependent. For example, the count of words related to power was positively associated with anxiety in women (r=0.07; P=.03), whereas it was negatively associated with anxiety in men (r=–0.09; P=.01).

Conclusions
Both acoustic and linguistic speech measures are associated with anxiety scores. The amount of speech, acoustic quality of speech, and gender-specific linguistic characteristics of speech may be useful as part of a system to screen for anxiety, detect relapse, or monitor treatment.
Remotely Delivered Behavioral Weight Loss Intervention Using an Ad Libitum Plant-Based Diet: Pilot Acceptability, Feasibility, and Preliminary Results
Authors: Chwyl Christina , Wright Nicholas , M Turner-McGrievy Gabrielle , L Butryn Meghan , M Forman Evan 
Published: May 2022

Background
Many traditional lifestyle interventions use calorie prescriptions, but most individuals have difficulty sustaining calorie tracking and thus weight loss. In contrast, whole food plant-based diets (WFPBDs) have previously shown significant weight loss without this issue. However, most WFPBD interventions are face-to-face and time-intensive, and do not leverage gold standard behavioral strategies for health behavior change.

Objective
This open pilot trial was the first to evaluate the feasibility of a fully featured, remotely delivered behavioral weight loss intervention using an ad libitum WFPBD.

Methods
Over 12 weeks, participants (N=15) with overweight or obesity received a newly designed program that integrated behavioral weight loss and a WFPBD prescription via weekly web-based modules and brief phone coaching calls. Assessments were performed at baseline, midtreatment (6 weeks), and after treatment (12 weeks).

Results
The intervention was rated as highly acceptable (mean 4.40 out of 5, SE 0.18), and attrition was low (6.7%). In all, intention-to-treat analyses revealed that 69% (10.4/15) of the participants lost 5% of their weight (mean –5.89, SE 0.68 kg). Predefined benchmarks for quality of life were met.

Conclusions
A pilot digital behavioral weight loss intervention with a non–energy-restricted WFPBD was feasible, and the mean acceptability was high. Minimal contact time (80-150 minutes of study interventionist time per participant over 12 weeks) led to clinically relevant weight loss and dietary adherence for most participants (10.4/15, 69% and 11.8/15, 79%, respectively), and quality of life improvements (reliable change indices >1.53). We hope that this work will serve as a springboard for future larger scale randomized controlled studies evaluating the efficacy of such programs for weight loss, dietary change, and quality of life.

Published: May 2022

Introduction. A new coronavirus infection (COVID-19) is a pathogenetically complex disease characterized by the involvement of the main human organs and systems in the pathological process, including the organs of the gastrointestinal tract (gastrointestinal tract).Purpose: to study the gastroenterological manifestations of COVID-19 in patients of mild and moderate severity based on the analysis of complex data, including computed tomography examination.Material and methods. The study included 80 patients hospitalized with a confirmed diagnosis of COVID-19 (19 patients with mild and 61 with moderate severity) who underwent a comprehensive original examination upon admission to the hospital and outpatient at week 8 of dynamic follow-up. In the complex therapy of 41 patients, the drug rebamipid was used. The scope of the examination included questionnaires, traditional clinical, clinical and laboratory, biochemical, instrumental and radiation studies, unique methods for studying microbiota and intestinal permeability. All patients also underwent computed tomography (CT) of the chest organs, followed by analysis and postprocessing of images of the upper abdominal cavity. The study also included a group of 43 inpatient patients with moderate severity of the disease, a group of 17 practically healthy patients was used as a control.Results and conclusions. A method of qualitative and quantitative assessment of the state of parenchymal and hollow organs of the upper abdominal cavity according to CT data is proposed. It was found that with moderate severity of COVID-19, quantitative criteria (attenuation coefficient of the liver, pancreas, bile) were subject to more pronounced deviations, as was the diameter of the colon. Additional diagnostic capabilities of the standard chest CT protocol in patients with COVID-19 are associated with postprocessor analysis of images of abdominal organs.

Introduction. Continuous improvement and increased availability of high-tech research methods, such as computed X-ray tomography (CT) and magnetic resonance imaging (MRI) with contrast enhancement, qualitatively change the diagnostic search for combined vascular pathology, including when conducting studies of other organs and systems, even in the absence of any clinical manifestations.The purpose of the study: to evaluate the possibilities and determine the indications for CT diagnosis of arteriovenous conflicts of the abdominal cavity, retroperitoneal space.Research objectives: to determine CT parameters and the algorithm of CT analysis of upper-level arteriovenous conflicts in modern radiation and urological aspects.Materials and methods. The study included 34 patients with arteriovenous conflicts of the abdominal cavity and retroperitoneal space detected by computer X-ray tomography. The average age of patients is 39±11.0 years; the number of male patients is 19 (55.9%), female — 15 (44.1%). Children’s patients accounted for 23.5% (8 people; average age 11±7 years). The preoperative diagnostic algorithm included a clinical examination, ultrasound diagnostics, a comprehensive study of laboratory parameters, CT-arterio/venography.The results of the study. Among the upper—level arteriovenous conflicts, superior mesenteric artery syndrome prevailed — it was observed in 23 patients (67.6%), of which aortomesenteric duodenal compression (Wilkie syndrome) was detected in 12 patients (52.2%); aortomesenteric venous compression (Nutcracker syndrome) — in 11 patients (47.8%). Among children’s patients, aortomesenteric tweezers prevailed (5 patients — 62.5%). A combination of upper-level syndromes was detected in 6 patients (17.6%). Compression syndrome of the left renal vein (aortovertebral venous compression, posterior nutcracker syndrome), or Nutcracker syndrome was detected in 11 patients (32.4%), which in all cases (100%) was a «random finding» of CT diagnostics.Conclusions. It is recommended to perform CT-, MR-studies with contrast enhancement (in angiography mode) in patients with a suspected diagnosis of arteriovenous conflict with the expansion of the scanning zone to the level of the abdominal cavity, retroperitoneal space and pelvis in order to exclude combined multi-level vascular pathology. Mandatory for radiation analysis are the magnitude of the aortomesenteric angle, the magnitude of the aortomesenteric distance for the left renal artery, the magnitude of the aortovertebral distance for the left renal artery, the magnitude of the aortomesenteric distance for the duodenum; analysis of concomitant variant vascular pathology at the levels studied.

Introduction. An urgent problem of oncogynecology is the diagnosis and treatment of patients with endometrial cancer, the steady growth of which is noted in most developed countries of the world and at the present stage occupies the 2nd place among neoplasms of the reproductive system of women.Purpose. To evaluate the informativity of complex ultrasound examination for diagnostics of endometrial cancer.Material and methods. There were examined 28 patients aged from 45 to 70 y.o. (23 menopausal women — 82,1% and 5 in reproductive status — 17,9%). The diagnosis of endometrial cancer was verified by morphologic and histologic methods. For all the patients there was performed the ultrasound examination including energy Doppler mode, ultrasound elastography, Doppler imaging of uterine and intratumoral vessels, evaluation of M-echo thickness, invasive growth index and rate of myometrial invasion. Studies were performed with ultrasound scanners «ACUSON 2000» by SIEMENS and «Aixplorer» by «SuperSonic Imagine S.A.».Results. Highly and moderately differentiated adenocarcinoma was revealed mostly in patients with Ia and Ib stages while low differentiated adenocarcinoma was revealed mostly in the III stage. The investigation performed ascertained that a complex ultrasound examination with application of dopplerography, sonoelastography, contrast enhanced sonography is highly informative for determination, staging and prediction of endometrial cancer.Conclusion. The results obtained indicate the high efficiency of the diagnostic complex used in identifying the characteristic features of intraorgan and tumor blood flow, as well as tissue stiffness, which play an important role in specifying the stage and prognosis of the disease.

O estudo objetiva compreender o processo de inclusão de uma aluna com deficiência visual em aulas de Matemática, em uma instituição da Educação Básica pública do estado do Paraná. A abordagem metodológica adotada é a pesquisa exploratória, com análise qualitativa de conteúdo, a partir de Bardin (2011). Os encaminhamentos para as análises foram apoiados na teoria Histórico-Cultural de Vigotski e na teoria de assimilação por etapas de Galperin. A coleta de registro de dados foi realizada por meio de observações sistemáticas na turma em que a aluna se encontrava matriculada, junto com entrevistas semiestruturadas com o diretor do estabelecimento, a professora de Matemática e a aluna participante. Os resultados foram sistematizados em duas categorias: a) processos metodológicos e recursos didáticos utilizados no ensino de Matemática para a aluna com deficiência visual; b) processo de inclusão no ambiente escolar. Verificou-se que a instituição escolar investigada busca oferecer uma educação inclusiva, entretanto, muitos desafios e barreiras se fazem presentes na efetivação da inclusão da aluna, em específico, tais como: a superlotação da turma, a falta de formação dos professores para realizar o ensino inclusivo, a carência de materiais adaptados, a ausência de piso tátil na escola, além de outras formas de acessibilidade estrutural.
Mengajar Kreativitas Dalam Profesionalisme Guru Matematika
Authors: C Jacob 
Published: May 2022

Pengembangan guru matematika professional diyakini merupakan salah satu strategi yang sangat berguna untuk pendidikan matematika tentang pentingnya perubahan yang diperlukan yang dialamatkan kepada tantangan yang sangat mendesak yang dihadapi pendidikan matematika. Hal ini didukung dengan penelitian, “pengembangan professional guru adalah kritis terhadap reformasi pendidikan sistemik dan perbaikan sekolah yang terfokus pada mempertinggi hasil belajar untuk semua anak”( Bredeson dalam Jacob, 2008).
Di samping itu, banyak penelitian dan penulisan pada kreativitas yang terfokus pada kreativitas individual, “bakat kuat” (“long genius”), yang kurang mendapat pengakuan dari faktor sosial dan kelompok yang mempengaruhi proses kreatif. Dengan demikian, professionalisme mencoba untuk mengerti faktor-faktor yang diperlukan untuk orang kreatif dan aktivitas orang kreatif. Jadi dalam kasus ini, personalitas, pengalaman perkembangan, kultur, motivasi dan keterampilan kognitif benar-benar merupakan beberapa faktor yang muncul untuk perilaku kreatif utama.

Digital technologies for oversize goods road transportation
Authors: Smirnova O. Y. , Ertman Yu. A. 
Published: May 2022

Introduction. The scheduling a transportation route of overweight and oversize goods by road is necessary to perform taken into account road traffic safety and security of artificial engineering structures (bridges, railway crossing and others). The monitoring and control of these procedures are performed by a licensing system in Russia. During the delivery a driver must carry out the transportation of such cargo within the approved route that is specified in a particular paper (authorization) located in the vehicle. Issues appear mostly during first shipment organization and when the route is outside the permanent vehicles location, when road network and bypass schemes are not familiar for the driver and the current GPS-systems bases do not include formal designations of roads according to state register. The authors suppose digital technologies implementation has to facilitate easier abnormal load shipments violations-free sufficiently.The Materials and methods. A transportation organisation model of abnormal loads by BPMN notation has been developed. The key control points have been determined by the authors on the base of their own experience.The results. An information model of forming and transmitting to the carrier authorization to transport abnormal load within the approved route has been developed. In the authorization the link to the cartographic resource is inserted in one of the QR-code field. Such approach makes possible to identify approved route clearly and unambiguously.Uniqueness and practical meaning. The information model uniqueness consists of the transmission way of approves route to the customer – not the sequence of transit localities, but the cartographic resource. The practical implementation of such decision is addressed to help a carrier (a driver) to perform the abnormal load transportation strictly within the approved route.

Published: May 2022

There are currently more than 10.000 cryptocurrencies available to buy from the online market, with a vast range of prices for each coin it sells. The fluctuation of each coin is affected by any social events or by several important companies or people behind it. The aim of this research is to compare three cryptocurrencies, which are Bitcoin, Ethereum, and Binance Coin, using Social Network Analysis (SNA) by visualizing them using Business Intelligence (BI Dashboard). This study uses the SNA parameters of degree, diameter, modularity, centrality, and path length for each network and its actors and their actual market price by crawling(data collecting process) from Twitter as one of the social media platforms. From the research conducted, the popularity of cryptocurrencies is affected by their market price and the activeness of their actors on social media. These results are important because they could help in the decision-making to buy cryptocurrencies with high popularity on social media because they tend to retain their value over time and could benefit from price spikes from influential people.
