Soil effects on plant distributions and potential migration in Eastern North America
Authors: Ni Ming , Vellend Mark
Published: April 2022

Many plant species are predicted to migrate poleward in response to climate change. Species distribution models (SDMs) have been widely used to quantify future suitable habitats and potential migration distances, but SDM studies typically neglect soil properties, despite their importance for plant fitness. In this study, we built three SDMs – one with only climate predictors, one with only soil predictors, and one with both climate and soil predictors – for each of 1870 plant species in Eastern North America (ENA), in order to investigate the relative importance of soil properties in determining plant distributions and potential migration under climate change. While climate variables were the most important predictors (mean relative importance = 0.573), soil properties also had a substantial influence on continental-scale plant distributions (mean relative importance = 0.369). Given spatial correlations between climate and soil variables, considerable variation in distributions cannot be uniquely attributed to one or the other. Under future climate scenarios, models including soil predicted much smaller northward shifts in distributions than climate-only models, strongly suggesting that high-latitude soils are likely to impede ongoing plant migration. Our findings highlight the necessity of incorporating soil properties into models and predictions for plant distributions and migration under environmental change.

Published: April 2022

In der vorliegenden Evaluationsstudie wurde die Wirkung der Lehre des universitären Lehrprojektes ‚Expertise und Kooperation für eine Basisqualifikation Inklusion‘ (EKBI) auf inklusionsbezogene Einstellungen, Haltungen und Selbstwirksamkeitserwartungen untersucht. Diese Lehre schloss jeweils Lehrtandems aus mindestens zwei Dozierenden sowie interdisziplinäre Kooperationen ein. Die Teilnehmenden der Kurse (Experimentalgruppe, n = 101) sowie Studierende, die nicht daran teilgenommen hatten (Kontrollgruppe, n = 54), wurden vor und nach dem Semester, in dem die Lehre stattfand, mittels Fragebogen untersucht. Bei der Entwicklung allgemeinerer Einstellungen, Haltungen und Bedenken konnte kein signifikanter Effekt der Zeit in Abhängigkeit von der Gruppe verzeichnet werden. Es zeigte sich aber, dass sowohl die spezifischen unterrichtsbezogenen Einstellungen als auch die subjektiv eingeschätzte Lehrer*innenwirksamkeit in Bezug auf Inklusion in der Experimentalgruppe stärker anstiegen als in der Kontrollgruppe. Es ist zu schlussfolgern, dass die Tandemlehre mindestens kurzfristig wirksam in Bezug auf eine proinklusive Entwicklung ist. Zukünftige Studien könnten die Nachhaltigkeit der Effekte sowie ihren Praxistransfer untersuchen.Abstract

In this study, we evaluated the effectiveness of courses at university with regard to develop positive attitudes, sentiments and self-efficacy in inclusive education. Courses comprised tandems of at least two lecturers and interdisciplinary cooperation. They were incorporated in the project ‘Expertise and Cooperation for a Basic Qualification in Inclusion’ (EKBI). Students who attended the tandem-courses (experimental group, n = 101) and students who did not (control group, n = 54) completed a questionnaire before and after the semester in which tandem-courses took place. Development of general sentiments, attitudes and concerns about inclusive education was independent of the group. But specific attitudes related to inclusive teaching as well as subjective ratings of personal teacher efficacy for inclusive practice increased stronger in the experimental group compared to the control group. Consequently, tandem-courses led to short-term effects in fostering open-mindedness for inclusion. Future studies could examine the sustainability of the present effects and their transfer into practical contexts.
Inklusive Bildung trotz Lehrer*innenmangel – Erfahrungen aus der Seiteneinstiegsqualifizierung im Hinblick auf inklusionsorientierte Lehrer*innenbildung
Authors: Leonhardt Nico
Published: April 2022

Die Gedanken und Erkenntnisse zur Gestaltung einer Lehrer*innenbildung, die Lehrkräfte für die Tätigkeit in inklusionsorientierten Schulen vorbereitet, sind umfassend im wissenschaftlichen Diskurs aufbereitet. Gleichzeitig sind Schulen und damit auch die ausbildenden Hochschulen durch einen spürbaren Lehrkräftemangel zunehmend damit konfrontiert, sogenannte Quer- und Seiteneinsteiger*innen für eine pädagogische Tätigkeit im Bildungssystem auszubilden. Der vorliegende Beitrag versucht diese beiden Themenbereiche miteinander zu verknüpfen, um damit auf eine Lücke im bisherigen wissenschaftlichen Diskurs aufmerksam zu machen. Mit Bezug zu Grundwerten und Kompetenzen, die als grundlegend für inklusive Bildung betrachtet werden, werden bisherige Erkenntnisse der grundständigen Ausbildung im Lehramt diskutiert und mit Erfahrungen der Qualifizierung von sogenannten Quer- und Seiteneinsteiger*innen in Beziehung gesetzt. Diese kritische Reflexion bezieht sich unter anderem auf Erfahrungen aus dem Projekt „wissenschaftliche Ausbildung von Lehrkräften in Sachsen“ (wAL).Abstract

The thoughts and findings on the design of teacher education that prepares teachers to work in inclusion-oriented schools are comprehensively discussed in the research literature. At the same time, due to the noticeable shortage of teaching staff, schools and thus also the universities that provide teacher education programs are increasingly confronted with the need to train so-called ‘lateral entrants’ for pedagogical work in the education system. The present contribution attempts to link these two topics in order to draw attention to a gap in the current academic discourse. With reference to basic values and competences that are considered fundamental for inclusive education, previous findings of basic education in the teaching profession are discussed and related to experiences of the qualification of ‘lateral entrants’. This critical reflection is based, among other things, on experiences from the project „wissenschaftliche Ausbildung von Lehrkräften in Sachsen“ (wAL).
Inklusion: Transfer von Forschungsbefunden in der frühen Bildung. Eigenlogiken und Systemdifferenz als Herausforderung
Authors: König Anke
Published: April 2022

Der Transfer von Inklusion in der frühen Bildung ist bedeutend für die Erziehung und Bildung in einer pluralen Gesellschaft. Unter Transfer wird hier die Verbreitung des Themas im System, aber auch die „von wissenschaftlichem Wissen in die Praxis verstanden“ (Gräsel, 2010). Das System der frühen Bildung und die Inklusionsdebatte werden anhand qualitativer Analysen beleuchtet. Herausgearbeitet wird, dass Inklusion stärker über die frühpädagogischen Reformdiskurse, d.h. entsprechender Projektanlagen als über Steuerungsinstrumente verbreitet wird. Eine tiefergreifende wissenschaftliche Orientierung für das Handeln in der Praxis wird kritisch diskutiert. Das fehlende Zusammenspiel von Forschung und der Ausbildung von frühpädagogischen Fachkräften verhindert die Weiterentwicklung des Systems.Abstract

Transfer of inclusion in early childhood education is essential for pedagogy in heterogeneous societies. Transfer means dissemination and transfer of science orientated knowledge for practice. The system of early childhood education is therefore analyzed (qualitative). The research findings show that inclusion is more influenced by different pedagogical change projects in early childhood education than from governance. The article also discusses how far practice is influence by science orientated knowledge. The lack of interaction between research and training of preschool teachers prevents pedagogical change.
Correction of menopausal disorders: new possibilities of menopausal hormone therapy
Authors: Karakhalis L. Yu.
Published: April 2022

Determining the role of menopausal hormone therapy in the era of covid infection is an urgent task. The reasons for the lower rate of severe outcomes in women against the background of covid infection compared to men are currently being discussed. This is suggestive of the idea that the female body has the protection that accounts for this advantage. that Scientific literature data were reviewed to select the best combination of estrogen and progesterone when used as menopausal hormone therapy in the present setting. During the analysis of the literature on the use of estrogens and progestins as menopausal hormone therapy published in recent years, we used the following sources: PubMed, E-libary, Scopus. The body of material, which we studied, led us to a conclusion about the preference for the gestagen component when menopausal hormone therapy was prescribed. Gestagen should have the lowest risks in the development of thrombosis, as well as level the pronounced symptoms of peri- and postmenopause. According to the sources we studied and the authors’ own clinical experience, levonorgestrel-containing menopausal hormone therapy preparations have a high safety profileImproving physicians’ literacy about the criteria for prescribing menopausal hormone therapy, including drugs containing two components, estrogen and levonorgestrel in a cyclic regimen, will allow the use of hormone therapy in a wider range of patients in the perimenopausal and postmenopausal periods.

Published: April 2022

Introduction. As is known, the development of invasive cervical cancer is preceded by cervical intraepithelial neoplasia of varying severity, which is a pathological process in which cells with varying degrees of atypia and impaired differentiation appear in the thickness of the stratified squamous epithelium of the cervix.

Objective. To study the  effect of  complex therapy in  patients with mild HPV-associated cervical intraepithelial neoplasia on the dynamics of local cytokine status and autoimmunity parameters.

Materials and methods. The study included 86 patients aged 35 to 40 years with morphologically verified mild cervical intraepithelial neoplasia. The main group consisted of 52 patients who, along with radio wave destruction of the cervix, were prescribed an immunostimulating drug with antiviral activity “Groprinosin-Richter” 1000 mg 3 times a day for 10 days 10–14 days before destruction and similar 2 courses after 10–14 days after it. The comparison group included 34 patients who underwent only radio wave destruction of the cervix.

Results. An analysis of the outcomes of low-grade squamous intraepithelial lesions after 6 months showed that in the main group, CIN I regression was observed in 92.3% of patients, persistence – in 7.7% of cases, while in the comparison group, CIN I regression was noted in 73,5% of cases, persistence – in 26.5% of patients.

Conclusions. Conducting complex therapy, including radio wave destruction and the use of a drug with immunostimulating and antiviral activity “Groprinosin-Richter” in  patients with low-grade HPV-associated cervical intraepithelial neoplasia, leads to the elimination of the initial imbalance of cytokines and normalization of autoantibody levels, helping to reduce the likelihood of HPV persistence and CIN progression to invasive cervical cancer uterus.
Modern treatment options for mixed and aerobic vaginitis
Authors: Apolikhina I. A. , Gorbunova E. A. , Efendieva Z. N.
Published: April 2022

Mixed vaginitis is closely associated with an increased risk of pelvic inflammatory disease, reproductive failures, preterm births, postpartum infectious and inflammatory complications, and cervical neoplasiae. The article considers the main issues of diagnosis and treatment of the disease, mainly caused by the polyetiological nature of mixed vaginitis and relapse tendencies. Effective techniques of integrated approach and impact on all etiological agents of mixed vaginitis with a minimal effect on the normal vaginal microflora are presented. In the modern obstetrics-gynecology practice, preference is given to combination drugs intended for topical use, and a rational choice of the dosage form ensures maximum patient compliance and treatment efficiency. It is topical dosage forms that contribute to the rapid delivery of the active substance to the inflammation site and do not have systemic effects characteristic of oral dosage forms. A new domestic multicomponent drug to treat vaginitis and prevent its development has been provided a market authorization on the Russian market. Its action is ensured by combined effects of the components in its composition, such as metronidazole (500 mg), chloramphenicol (200 mg), natamycin (150 mg), hydrocortisone acetate (15 mg), due to which the drug provides a wide range of etiotropic and symptomatic effects. The article presents the results of comparative clinical studies on assessment of the efficacy, tolerability and safety of the drug in the treatment of vulvovaginitis of mixed etiology. The Russian studies showed that this combination provides a minimal risk of systemic effects and the most favourable safety and tolerability profile of therapy as compared to the oral dosage forms, which gives grounds to recommend it for use in the clinical obstetrics-gynecology practice.

Published: April 2022

Introduction. A comparative analysis of urinary and recombinant gonadotropins is relevant for the enhancement of the effectiveness of assisted reproductive technologies (ART) programs. Of particular interest is the analysis of the pharmacoeconomic efficiency of highly purified human menopausal gonadotropins (HMG) and the identification of individual groups of patients for whom the use of these drugs for ovarian stimulation in the ART program is most feasible and economically justified.

Aim. To conduct a cost-effectiveness analysis of the use of Menopur Multidose at a dosage of 1200 IU for ovarian function stimulation in the standard ART protocols with gonadotropin-releasing hormone agonists and antagonists (GnRH-a and GnRH-ant).

Materials and methods. The retrospective study included 4080 women aged 20 to 43 years. Stimulation of ovarian function in the ART program was carried out according to the GnRH antagonist protocol in 65.8% of patients and according to the GnRH-a protocol using Menopur Multidose at a dosage of 1200 IU supplemented with Menopur at a dosage of 75 IU used for its indications in 34.2% of women.

Results and discussion. The clinical and laboratory data of the patients, stimulated cycle parameters, characteristics of the embryological stage, and the results of the ART program were analysed. The characteristics of the embryological stage met the KPI criteria, reflecting the key performance indicators of the embryology laboratory. Pharmacoeconomic analysis showed high involvement and adherence of patients to the treatment. In addition, it was found that the use of HMG makes efficient use of the budget within the average compulsory health insurance (CHI) tariff and accounts for 12% of the total tariff.

Conclusion. Prescription of highly purified HMG (Menopur Multidose 1200 IU) to stimulate ovarian function in patients of different ages is accompanied by an adequate number of mature oocytes, good quality blastocysts, as well as satisfactory indicators of clinical pregnancy. A cost-effectiveness analysis of the use of Menopur Multidose at a dosage of 1200 IU showed that the prescription of this drug is clinically justified and economically feasible in patients of different age groups.

Published: April 2022

The mechanical properties of the steel-concrete joint determine the mechanical properties of the whole bridge. The mechanical properties of the steel-concrete joint of Jianhua railway rigid-frame bridge are analyzed by using nonlinear finite element method. The results show that the overall stiffness transition of the joint is smooth, the maximum stress of concrete section and steel box girder section are lower than the design value of the strength, which indicates that the structural stiffness and strength of the steel-concrete joint section meets the requirements. The error range of the finite element analysis results and the measured data is within 6 %, which shows that the finite element method can simulate the actual stress state of the bridge and it could save a lot of time and energy compared to the actual test.
Experimental study on stress wave propagation in jointed rock coupling the effect of JMC & JRC
Authors: Hong Shengnan , Li Haibo
Published: April 2022

The objective of this study is to experimentally investigate how the rough joints effect the stress wave propagation through jointed rocks coupling the effect of the joint matching coefficient (JMC) and joint roughness coefficient (JRC). The Split Hopkinson Pressure Bar (SHPB) apparatus was adopted to conduct uniaxial compression experiments on jointed specimens. The joint matching coefficient (JMC) and joint roughness coefficient (JRC) are introduced as morphology parameters to estimate joint roughness. Based on SHPB experiments, we found out that the joint matching coefficient (JMC) has a greater influence on the transmission and reflection coefficient than the joint roughness coefficient (JRC). Jointed specimens with lower JMC and JRC make less energy transmitted through it and have a smaller transmission coefficient and bigger reflection coefficients. Also, the joint with lower JMC and JRC has less initial stiffness and greater maximum closure.
Study on treatment of loess subgrade disease by cement mixing pile
Authors: Dong Lishan
Published: April 2022

Affected by the difference of geological conditions, the cause of settlement of road subgrade is different, and the concealment of subgrade disease is strong. If it is not timely maintenance, it will cause the further development of subgrade disease. A finite element model is established to study the settlement control technology by using cement mixing pile for collapsible loess. The results showed that when the loess is relatively shallow and the cement mixing pile penetrates the loess, the settlement and post-construction settlement of the foundation are small, which can be controlled within the limits of the specification. The cement content of mixing pile should be selected according to different regions, moisture content and other indicators. For the loess with particularly high moisture content and organic matter content, the cement content and construction technology should be determined by indoor and on-site test pile.

Authors: Zhang Xiang , Jiao Yinghou , Qu Xiuquan , Zhao Zhiqian
Published: April 2022

The computational fluid dynamics (CFD) method is an efficient way to reduce the obstacles in fluid studies. Good use of the CFD method on the seal-rotor system area was proven again in this paper. The flow analyses of a new type of annular seal, the hole diaphragm labyrinth seal (HDLS), were studied by Fluent. Complex working conditions were considered to further understand the flow field variation trend. The results show that the maximum velocity component was obtained in the middle cavities perpendicular to the whirl direction. The velocity distributions before the first cavity and behind the last cavity show a different trend under a 50 Hz whirl frequency than that of other whirl frequencies, which can be described by the most apparent throttling effect of the first blade and the diffuse effect behind the last blade. It is helpful to further understand different annular seal characteristics by detailed fluid information analyses.

The article considers the tasks associate with the study of dynamic processes of interaction between rolling stock and railways. Studies of the interaction of a wheel with a rail, fitting the vehicle into curves when modeling critical and emergency situations do not allow oversimplification of basic differential equations. And they should be based on exact nonlinear equations that take into account the entire set of geometric and kinematic relationships without simplification. An objective assessment dynamic characteristic of the vehicle can only be obtained by simultaneously taking into account both its vertical and horizontal irregularities. In order to determine boundaries of parametric resonance, article proposes method of generalized Hill’s determinants, the application of which is possible without taking into account small parameters.

Authors: Chen Yumin , Ni Songtao , Chen Runze , Wu Kang
Published: April 2022

Traditional cavity reinforcement technology is difficult to effectively protect the cavity from damage caused by modern large-yield explosions, and the anti-explosion performance of prestressed anchor cables needs to be improved urgently. The design of a new prestressed high-elastic fully adhesive anchor cable for the enhancement of the anti-explosion effects of the anchor cable is presented in this paper. A constitutive model of the anchor cable is established in FLAC 3D and used to restore an equal scale field anti-explosion test. The reinforcement effects of the new anchor cable are compared with the conventional one’s. Results show that the stresses of the anchor cables differ at different locations: the anchor cable at the arch crown of the cavern is the one mainly under pressure with the compressive strain of the new anchor cable reduced by 25 %; while the anchor cable at the arch foot of the cavern is the one mainly under tension and the tensile strain of the new anchor cable is reduced by 26.3 %. The vertical displacement of the arch crown is reduced by 16.2 % with the reinforcement of the new anchor cable. The new anchor cable performs much better on the reinforcement of the cavern than the conventional one in the aspects of stress, strain and displacement, which provides a basis for the design of new anchor cables and their applications in engineering.

The Burden of Racial Innocence: British-Invasion Rock Memoirs and the U.S. South
Authors: Sutton Matthew
Published: April 2022

Mid-sixties British rock musicians have rationalized their firsthand experience and profitable interactions with American racial segregation by adopting a stance of racial innocence, or a belief that youth and virtue make one immune to charges of complicity with organized structures of racism. This almost childlike subject-positioning disingenuously separates musicians’ expertise on African American blues from a more mature acknowledgement of the oppressive racial conditions that shaped the music, implicitly excluding them from culpability in the continued imbalance of power between black and white musicians.
Autobiography and the Autobiographical Mode as Narrative Resistances. An Interdisciplinary Perspective
Authors: Zekri Masson Souhir
Published: April 2022

If every human gesture is autobiographical, then autobiographical genres and modes are being enriched day by day by contemporary and emerging disciplines and fields which do not necessarily belong to life writing. When it comes to trauma and war studies, the autobiographical imposes itself in a variety of thematic and structural ways in order to express the subjectivity of the oppressed, not without difficulties. This international and inter-disciplinary cluster of articles proposes to explore autobiography through the filiation narrative, autofiction, the anecdote, the body, the rewriting of the Grand Historical narratives, namely World War Two and the Franco-Algerian conflict, and the deconstruction of such binary oppositions as War Vs Peace and Lived Trauma Vs Narrated Trauma. The present introduction to the cluster will first introduce the genre of life writing in general, and autobiography in particular, by tracing its evolution towards a postmodern, more metabiographical stance. It will then summarize and comment on each article in the cluster so as to highlight their shared thematic patterns and the various findings which are pertinent to the fields of autobiography, trauma and war studies. The final section of the introduction will provide a new perspective on Freudian studies through the lens of auto/biography and metabiography.
Auster in? Auster out: Lifewriting as a Game? A novelist turns into an editor for the purposes of a unique experiment in lifewriting …
Authors: Gouverneur Michel-Guy
Published: April 2022

Life as the touchpoint between language and silence, the said and the unsaid. Take a famous writer who offers his readers to take part in an exercise in lifewriting? Based on life’s ability to be condensed into an atom of experience, Paul Auster’s collection of stories tackles the problem of preserving reality for readers outside this experience. For Wittgenstein the linguistic cradle shapes each person’s life, for themselves and for others. The stories show that people spontaneously turn their lives into narratives, often relying on unspoken data. Here lies the life / experience distinction : experience becomes a metaphor making life understandable. Secondly, whatever is alive is humanized; conversely, time structures and the social context are constant props of reality. Surprisingly, acausal connections (e.g. coincidences) are a recurring feature in lifewriting — a way of transcending space and time. Wittgenstein’s concept of lebensform (what is said about life initially and eventually forms your life itself) explains why the stories make sense. Lifewriting means discovering one’s freedom, which ultimately raises the issue of the subject : the one who is free ? the one who has found oneself?

Published: April 2022

Background

Since the publication of the Convention on the Rights of Persons with Disabilities, several countries have adopted laws, policies, and action plans to improve the universal accessibility of environments to improve inclusion and social participation of all citizens. Different organizations are involved in the application of these measures.

Objective

The aim of this study is to identify strategies that are contextually appropriate and provide guidelines for organizations to promote successful implementation of universal accessibility.

Methods

We will conduct a scoping review identifying implementation strategies of universal accessibility measures in local organizations using the Arksey and O’Malley framework. We will search in Medline, CINHAL, Urban Studies Abstracts, ABI Inform, and Social Sciences Full Text from 2006 until today, following the adoption of the Convention on the Rights of Persons with Disabilities. Two reviewers will independently select studies for inclusion and will extract the data. A descriptive and thematic analysis of the characteristics of the identified implementation strategies will be performed.

Results

Implementation strategies will be summarized in tables. They will then be linked to various constructs and domains listed in the Theoretical Domain Framework to identify barriers and facilitators of organizations’ uptake of evidence-based strategies of implementation.

Conclusions

We will tabulate the characteristics of the included studies and the outcomes of implementation strategies in them. The results of this scoping review are expected to help the research community in various fields, local organizations, and stakeholders to identify better ways to improve implementation strategies of universal accessibility practices.

Automatic e-coaching may motivate individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Multiple studies have reported on uninterrupted and automatic monitoring of behavioral aspects (such as sedentary time, amount, and type of physical activity); however, e-coaching and personalized feedback techniques are still in a nascent stage. Current intelligent coaching strategies are mostly based on the handcrafted string messages that rarely individualize to each user’s needs, context, and preferences. Therefore, more realistic, flexible, practical, sophisticated, and engaging strategies are needed to model personalized recommendations.

Objective

This study aims to design and develop an ontology to model personalized recommendation message intent, components (such as suggestion, feedback, argument, and follow-ups), and contents (such as spatial and temporal content and objects relevant to perform the recommended activities). A reasoning technique will help to discover implied knowledge from the proposed ontology. Furthermore, recommendation messages can be classified into different categories in the proposed ontology.

Methods

The ontology was created using Protégé (version 5.5.0) open-source software. We used the Java-based Jena Framework (version 3.16) to build a semantic web application as a proof of concept, which included Resource Description Framework application programming interface, World Wide Web Consortium Web Ontology Language application programming interface, native tuple database, and SPARQL Protocol and Resource Description Framework Query Language query engine. The HermiT (version 1.4.3.x) ontology reasoner available in Protégé 5.x implemented the logical and structural consistency of the proposed ontology. To verify the proposed ontology model, we simulated data for 8 test cases. The personalized recommendation messages were generated based on the processing of personal activity data in combination with contextual weather data and personal preference data. The developed ontology was processed using a query engine against a rule base to generate personalized recommendations.

Results

The proposed ontology was implemented in automatic activity coaching to generate and deliver meaningful, personalized lifestyle recommendations. The ontology can be visualized using OWLViz and OntoGraf. In addition, we developed an ontology verification module that behaves similar to a rule-based decision support system to analyze the generation and delivery of personalized recommendation messages following a logical structure.

Conclusions

This study led to the creation of a meaningful ontology to generate and model personalized recommendation messages for physical activity coaching.
Pretrained Transformer Language Models Versus Pretrained Word Embeddings for the Detection of Accurate Health Information on Arabic Social Media: Comparative Study
Authors: Albalawi Yahya , Nikolov Nikola S , Buckley Jim
Published: April 2022

Background

In recent years, social media has become a major channel for health-related information in Saudi Arabia. Prior health informatics studies have suggested that a large proportion of health-related posts on social media are inaccurate. Given the subject matter and the scale of dissemination of such information, it is important to be able to automatically discriminate between accurate and inaccurate health-related posts in Arabic.

Objective

The first aim of this study is to generate a data set of generic health-related tweets in Arabic, labeled as either accurate or inaccurate health information. The second aim is to leverage this data set to train a state-of-the-art deep learning model for detecting the accuracy of health-related tweets in Arabic. In particular, this study aims to train and compare the performance of multiple deep learning models that use pretrained word embeddings and transformer language models.

Methods

We used 900 health-related tweets from a previously published data set extracted between July 15, 2019, and August 31, 2019. Furthermore, we applied a pretrained model to extract an additional 900 health-related tweets from a second data set collected specifically for this study between March 1, 2019, and April 15, 2019. The 1800 tweets were labeled by 2 physicians as accurate, inaccurate, or unsure. The physicians agreed on 43.3% (779/1800) of tweets, which were thus labeled as accurate or inaccurate. A total of 9 variations of the pretrained transformer language models were then trained and validated on 79.9% (623/779 tweets) of the data set and tested on 20% (156/779 tweets) of the data set. For comparison, we also trained a bidirectional long short-term memory model with 7 different pretrained word embeddings as the input layer on the same data set. The models were compared in terms of their accuracy, precision, recall, F1 score, and macroaverage of the F1 score.

Results

We constructed a data set of labeled tweets, 38% (296/779) of which were labeled as inaccurate health information, and 62% (483/779) of which were labeled as accurate health information. We suggest that this was highly efficacious as we did not include any tweets in which the physician annotators were unsure or in disagreement. Among the investigated deep learning models, the Transformer-based Model for Arabic Language Understanding version 0.2 (AraBERTv0.2)-large model was the most accurate, with an F1 score of 87%, followed by AraBERT version 2–large and AraBERTv0.2-base.

Conclusions

Our results indicate that the pretrained language model AraBERTv0.2 is the best model for classifying tweets as carrying either inaccurate or accurate health information. Future studies should consider applying ensemble learning to combine the best models as it may produce better results.

Background

During the COVID-19 pandemic, to prevent the spread of the virus, federal regulatory barriers around telemedicine were lifted, and health care institutions encouraged patients to use telemedicine, including video appointments. Many patients, however, still chose face-2-face (f2f) appointments for nonemergent clinical care.

Objective

We explored patients’ personal and environmental barriers to the use of video appointments from April 2020 to December 2020.

Methods

We conducted qualitative telephone interviews of Mayo Clinic patients who attended f2f appointments at the Mayo Clinic from April 2020 to December 2020 but did not utilize Mayo Clinic video appointment services during that time frame.

Results

We found that, although most patients were concerned about preventing COVID-19 transmission, they trusted Mayo Clinic to keep them safe when attending f2f appointments. Many expressed that a video appointment made it difficult to establish rapport with their providers. Other common barriers to video appointments were perceived therapeutic benefits of f2f appointments, low digital literacy, and concerns about privacy and security.

Conclusions

Our study provides an in-depth investigation into barriers to engaging in video appointments for nonemergent clinical care in the context of the COVID-19 pandemic. Our findings corroborate many barriers prevalent in the prepandemic literature and suggest that rapport barriers need to be analyzed and problem-solved at a granular level.
