Published: May 2022

Background: The proliferation of digital commerce has allowed merchants to reach out to a wider customer base, prompting a study of customer reviews to gauge service and product quality through sentiment analysis. Sentiment analysis can be enhanced through subjectivity and objectivity classification with attention mechanisms. Methods: This research includes input corpora of contrasting levels of subjectivity and objectivity from different databases to perform sentiment analysis on user reviews, incorporating attention mechanisms at the aspect level. Three large corpora are chosen as the subjectivity and objectivity datasets, the Shopee user review dataset (ShopeeRD) for subjectivity, together with the Wikipedia English dataset (Wiki-en) and Internet Movie Database (IMDb) for objectivity. Word embeddings are created using Word2Vec with Skip-Gram. Then, a bidirectional LSTM with an attention layer (LSTM-ATT) imposed on word vectors. The performance of the model is evaluated and benchmarked against classification models of Logistics Regression (LR) and Linear SVC (L-SVC). Three models are trained with subjectivity (70% of ShopeeRD) and the objectivity (Wiki-en) embeddings, with ten-fold cross-validation. Next, the three models are evaluated against two datasets (IMDb and 20% of ShopeeRD). The experiments are based on benchmark comparisons, embedding comparison and model comparison with 70-10-20 train-validation-test splits. Data augmentation using AUG-BERT is performed and selected models incorporating AUG-BERT, are compared. Results: L-SVC scored the highest accuracy with 56.9% for objective embeddings (Wiki-en) while the LSTM-ATT scored 69.0% on subjective embeddings (ShopeeRD). Improved performances were observed with data augmentation using AUG-BERT, where the LSTM-ATT+AUG-BERT model scored the highest accuracy at 60.0% for objective embeddings and 70.0% for subjective embeddings, compared to 57% (objective) and 69% (subjective) for L-SVC+AUG-BERT, and 56% (objective) and 68% (subjective) for L-SVC. Conclusions: Utilizing attention layers with subjectivity and objectivity notions has shown improvement to the accuracy of sentiment analysis models.

Authors: Zvonareva Ntaliya A. , Kovalenko Roman K. 
Published: May 2022

Purpose. To study the relationship between a person’s self-concept and their interests and fulfillment in the four spheres of life: communication, resources, cognition and power.
Work method/methodology. For this purpose, we used an originally authored methodology for the identification of personality types as per the A. Afanasyev's typology and a questionnaire that the authors designed to identify person's interests, preferences and desires, and calculated the point-biserial correlation coefficient.
Findings. The research ascertained a statistically significant correlation between person's perceptions of their potency and their interest in fulfilling in the four spheres of life: communication, resources, cognition and power. We found that there is a positive correlation between a person's self-esteem concerning the four spheres and a corresponding level of their ambition, as well as between the number of intrapersonal conflicts in a sphere and a strategy of these conflicts' resolution.
Application of the findings. The suggested psychoanalysis-based typology will benefit recruiters and other helping profession specialists, who will be able to quickly evaluate person's childhood experiences and their prospects for fulfillment in a given capacity.

Authors: Kulikova Tatyana I. 
Published: May 2022

Purpose. The article is devoted to the study of the presence of a connection between resilience and maladaptive schemas in students of different ages.
Method. Studying of the correlation between resilience and maladaptive schemas among students of different ages has been conducted on a sample of 67 students of Tula State Lev Tolstoy Pedagogical University students, aged 18 to 24, in the number of 67 people. As diagnostic material, the study uses Maddi’s Hardiness Survey; Young Schema Questionnaire “YSQ-S3R”. Methods of mathematical statistics include Pearson correlation coefficient (PCC). Correlation analysis has revealed the presence of strong inverse correlations between the resilience with maladaptive schemas “Vulnerability to Harm or Illness” and “Mistrust” (r=-0.578 and r=-0.499 at a significance level of p<0.01), “Subjugation” (r=-0.486), “Failure” (r=-0.443), “Unrelenting Standards” (r=-0.441), “Dependence/Incompetence” (r=-0.431) and “Defectiveness” (r=-0.424) at p<0.01.
Results. The study has shown that resilience is a dynamic process caused by the age-psychological characteristics of an individual, including early maladaptive patterns of behavior. This is evidenced by differences in the structure of resilience in different age groups, as well as an increase in the level of resilience from youth to youth.
Practical implications. The research materials can be used in the work of the psychological service of an educational organization. Understanding the detailed content of the process of becoming resilience contributes to the purposefulness of developmental and psychoprophylactic work.
DEVELOPMENT OF A TRAINING FOR THE FORMATION OF INFORMATION- PSYCHOLOGICAL STABILITY OF THE PERSONALITY OF UNIVERSITY STUDENTS
Authors: Meyerson Ayzek-Leyb S. 
Published: May 2022

Introduction. The article is devoted to the development of a training program for the formation of information-psychological stability of the personality of university students. Transformational processes taking place in society contributed to the rapid information and communication development, which has its positive and negative sides for the development of the individual. Today, the negative impact that Internet technologies have on a person is already clearly visible, reducing his adaptive capabilities, destructively reducing the level of well-being and affecting the psychoemotional state. This contributes to the search for ways to form informational and psychological stability of the individual. Materials and methods. In the course of writing the article, a theoretical analysis of domestic and foreign scientific sources was used, the study of scientific articles and publications on the topic; methodological development and justification of the training program.
Research results. Approaches to understanding the concept of an informational secure environment and a person's resistance to negative informational impact have been systematized. The concept of psychological stability has been expanded, and the concept of information and psychological stability has been substantiated. The factors that determine psychological stability and structural elements that ensure the effectiveness of psychological stability are highlighted. On the basis of theoretical analysis and previously conducted research, a training program for the formation of information-psychological stability of university students has been developed, which will provide a sufficient level of formation of socio-cultural identity, safe information behavior, promote self-regulation and self-control; assimilation of norms of behavior in society.
Discussion and conclusions. Information and psychological stability focuses on the personal aspects of the perception of information coming from the external environment, in particular the Internet environment, and allows a person to rationally respond to social risks. In the course of the methodological analysis, it was determined that the optimal information-psychological stability can be formed through the development of socio-cultural identity, self-motivation, pro-social behavior, critical thinking, self-identification and positive self-attitude, tolerance in attitudes towards others.
DEVELOPING STUDENTS’ RESEARCH AND SELF-STUDY SKILLS: THEORETICAL BACKGROUND
Authors: Sergeeva Olga N. 
Published: May 2022

Background. The context and the science tasks have changed recently which means that there is a need for an updated methodology to form and develop university students’ ability to do a research, i.e. to plan, carry out and present its’ results. Before we develop an educational program or a course that is aimed at developing this set of skills, it is important to break the whole process down into stages so that we could see the progress of a student doing a research at university who is getting more and more self-reliant from the start to the end of a project.
Materials and methods. The research was done by means of literature review and experience analysis in order to identify pedagogical and methodological background issues that underlie the process of mastering the research skills as part of the self-study competence at university.
Results. Based on the findings, we suppose that there are four stages; we called them the (1) Introductory (controlled) stage, (2) Forming (guided) stage, (3) Creative (free) stage, and (4) Independent (reflective-analytical) stage. All four stages smoothly follow one another stimulating and supporting students while they are involved in a research project till they are able to cope with it with the minimum support provided by a third party.
Conclusion. The developed scheme of the stages can also serve as a basis for the life-long learning afterwards. When a student masters this set of skills at all four levels, he or she is then capable of repeating the experience starting with the very first stage in another context in their home country or abroad – at another university, research organization, or in another field of research.
Incentive-Compatible Forecasting Competitions
Authors: Witkowski Jens , Freeman Rupert , Vaughan Jennifer Wortman , Pennock David M. , Krause Andreas 
Published: May 2022

We initiate the study of incentive-compatible forecasting competitions in which multiple forecasters make predictions about one or more events and compete for a single prize. We have two objectives: (1) to incentivize forecasters to report truthfully and (2) to award the prize to the most accurate forecaster. Proper scoring rules incentivize truthful reporting if all forecasters are paid according to their scores. However, incentives become distorted if only the best-scoring forecaster wins a prize, since forecasters can often increase their probability of having the highest score by reporting more extreme beliefs. In this paper, we introduce two novel forecasting competition mechanisms. Our first mechanism is incentive compatible and guaranteed to select the most accurate forecaster with probability higher than any other forecaster. Moreover, we show that in the standard single-event, two-forecaster setting and under mild technical conditions, no other incentive-compatible mechanism selects the most accurate forecaster with higher probability. Our second mechanism is incentive compatible when forecasters’ beliefs are such that information about one event does not lead to belief updates on other events, and it selects the best forecaster with probability approaching one as the number of events grows. Our notion of incentive compatibility is more general than previous definitions of dominant strategy incentive compatibility in that it allows for reports to be correlated with the event outcomes. Moreover, our mechanisms are easy to implement and can be generalized to the related problems of outputting a ranking over forecasters and hiring a forecaster with high accuracy on future events.This paper was accepted by Yan Chen, behavioral economics and decision analysis.Funding: This work was supported by the European Research Council [Grant ERC StG 307036] and the National Science Foundation [Grant CCF-1445755].

Significant statistical differences were found in multiple outcome measures after implementing photobiomodulation near infrared. Conclusions Photobiomodulation near infrared is a promising intervention for postpartum mothers.
Development of a surgical wound assessment tool to measure healing and risk factors for delayed wound healing in Vietnam: a Delphi process
Authors: Do Hien Thi Thu , Edwards Helen , Finlayson Kathleen 
Published: May 2022

Objective: To identify items and develop a surgical wound assessment tool (SWAT) to measure progress in healing and early detection of risk factors for delayed healing in surgical wounds in patients in Vietnam. Method: The development process included two phases: (i) development of the initial SWAT based on evidence-based guidelines, results of a literature review and consultation with surgeons; and (ii) a Delphi process with wound care nurse experts to refine and provide consensus on a final version of the SWAT. Data collection took place between April–August 2017. Results: In phase one, 22 items were included and were evaluated by ten Vietnamese surgeons, with item-content validity index (I-CVI) scores of 1.00 in 17 out of 22 items. The remaining items had I-CVI ranking of 0.8 to 0.9. The overall scale-content validity index was 0.97. Eight more items were recommended for inclusion, increasing the total to 30 items. In phase two, 21 Vietnamese nurse wound care experts completed all three rounds of the Delphi process. After three rounds, 24 items out of 30 reached full consensus for the final tool. Conclusion: This study was the first step to confirm the content validity of the newly developed SWAT. Further development of the tool including the evaluation of validity and reliability was undertaken to strengthen the tool.
End-to-end service provisioning based on extended segment routing in multi-domain optical networks of F5G

Published: May 2022

As the most important fabric of fixed networks, the optical network plays an important role in expanding network capacity and providing long distance communication. At present, the fixed network has entered a key era, i.e., the fifth-generation fixed network (F5G). As one of the main features of F5G, the full-fiber connection requires a tenfold to hundredfold increase in the number of connections, which means F5G will have tens of thousands of nodes and millions of connections. Large-scale networks are composed of multiple network domains connected to each other. The whole network can be subdivided according to network functional domain. To meet different service requirements, how to provision fast end-to-end service in a multi-domain scenario has become a key issue. In optical networks, lightpath establishment must precede service transmission. The latency of lightpath establishment includes lightpath establishment signaling latency and optical interleaving device configuration latency. The latter depends on equipment performance. Therefore, how to provision fast lightpath establishment signaling is a key problem. To reduce end-to-end service provisioning latency, we propose an extended-segment-routing-based fast service provisioning scheme for the first time, to our knowledge, which consists of two steps: signaling path acquisition and signaling provisioning. For the signaling path acquisition step, we propose an adaptive segment routing (ASR) algorithm that first performs service path calculation based on service requirements, then performs a label compression algorithm to obtain the signaling path represented by the minimum number of labels according to the service path. For the signaling provisioning step, we propose a fast-signaling provisioning (FSP) process that can realize fast signaling provisioning in both single-domain and multi-domain scenarios. The simulation results show that, (1) compared to the Dijkstra algorithm, the ASR algorithm achieves a lower blocking probability for service and a better label compression effect for reducing the number of labels representing the signaling path, and, (2) compared to the traditional distributed signaling provisioning process and centralized signaling provisioning process, the FSP process achieves lower end-to-end latency.
Associations between prisons and recidivism: A nationwide longitudinal study
Authors: Yu Rongqin , Långström Niklas , Forsman Mats , Sjölander Arvid , Fazel Seena , Molero Yasmina 
Published: May 2022

Objectives
To examine differences in recidivism rates between different prisons using two designs—between-individual and within-individual—to account for confounding factors.

Methods
We examined recidivism rates among 37,891 individuals released from 44 Swedish prisons in three security levels, and who were followed from 2006 to 2013. We used longitudinal data from nationwide registers, including all convictions from district courts. First, we applied a between-individual design (Cox proportional hazards regression), comparing reconviction rates between individuals released from prisons within the same security level, while adjusting for a range of individual-level covariates. Second, we applied a within-individual design (stratified Cox proportional hazards regression), comparing rates of reconviction within the same individuals, i.e., we compared rates after release from one prison to the rates in the same individual after release from another prison, thus adjusting for all time-invariant confounders within each individual (e.g. genetics and early environment). We also adjusted for a range of time-varying individual-level covariates.

Results
Results showed differences in the hazard of recidivism between different prisons in between-individual analyses, with hazards ranging from 1.22 (1.05–1.43) to 4.99 (2.44–10.21). Results from within-individual analyses, which further adjusted for all time-invariant confounders, showed minimal differences between prisons, with hazards ranging from 0.95 (0.87–1.05) to 1.05 (0.95–1.16). Only small differences were found when violent and non-violent crimes were analyzed separately.

Conclusions
The study highlights the importance of research designs that more fully adjust for individual-level confounding factors to avoid over-interpretation of the variability in comparisons across prisons.

Authors: Pinto-Ramos João , Moreira Tiago , Costa Frederico , Tavares Helena , Cabral João , Costa-Santos Cristina , Barroso Joana , Sousa-Pinto Bernardo 
Published: May 2022

Introduction
The Handheld Dynamometer (HHD) has the potential to overcome some of the logistic and economic limitations of isokinetic dynamometers for measuring knee extension muscle strength. However, its reliability has not been fully assessed. The purpose of this study is to measure intra and inter-rater reliability of HHD for knee extension strength in patients receiving rehabilitation treatment, as well as to understand in which conditions is the reliability higher.

Methods
Twenty-nine patients admitted in an inpatient Physical Medicine and Rehabilitation unit were consecutively included in this cross-sectional study. Two experienced and two inexperienced physicians made two assessments of knee extension strength with HHD, separated by three hours. Intraclass Correlation Coefficients (ICC), absolute differences between assessments, and correlations between strength and functional variables were calculated.

Results
Intra and inter-rater ICC were overall high (≥ 0.950 and 0.927, respectively). Higher values were found when average of two measurements were made for estimating intra-rater ICC (ICC = 0.978; 95%CI = 0.969–0.985) but not for inter-rater ICC. ICC were not statistically significantly different when calculated based on measurements performed by inexperienced physicians and experienced ones. There was a moderate correlation between strength and functional variables.

Conclusion
Handheld Dynamometer seems to be a reliable option to measure knee extension muscle strength, particularly when two measurements are performed and their average is reported.

Published: May 2022

Objective
Low-level viraemia (LLV) occurs in some people with HIV (PWH) receiving antiretroviral therapy (ART) and has been linked to inferior treatment outcomes. We investigated factors associated with LLV in a nationwide cohort of Swedish PWH starting ART.

Methods
Participants were identified from the InfCareHIV register, with the following inclusion criteria: ART initiation 2006–2017, age >15 years, ≥4 viral load (VL) results available and no documented treatment interruptions or virologic failure (≥2 consecutive VL ≥200 copies/ml) during follow-up. Starting from 6 months after ART initiation, participants were followed for 24 months and categorised as viral suppression (VS; VL <50 copies/ml) or LLV (≥2 consecutive VL 50–199 copies/ml). We analysed the association between the following factors and LLV using multivariable logistic regression: sex, age, pre-ART VL and CD4 count, ART regimen, country of birth, HIV-1 subtype and transmission category.

Results
Among 3383 participants, 3132 (92.6%) had VS and 251 (7.4%) had LLV. In univariable analyses, factors associated with LLV were male sex, higher age, lower pre-ART CD4 count, higher pre-ART VL and ART regimen. After adjustment, the following factors were associated with LLV (adjusted odds ratio; 95% confidence interval): male sex (1.6; 1.1–2.3), higher pre-ART VL (2.7; 2.2–3.3), pre-ART CD4 count <200 cells/μl (1.6; 1.2–2.2), protease inhibitor (PI)-based regimen (1.5; 1.1–2.1), non-standard ART (2.4; 1.0–5.5) and injecting drug use (2.0; 1.1–3.7).

Conclusion
Among Swedish PWH, LLV during ART was associated with markers of HIV disease severity before starting ART, male sex, injecting drug use and use of PI-based or non-standard ART regimens.
