Robotic Assisted Upper Limb Training Post Stroke: A Randomized Control Trial Using Combinatory Approach Toward Reducing Workforce Demands

Post stroke upper limb rehabilitation is a challenging problem with poor outcomes as 40% of survivors have functionally useless upper limbs. Robot-aided therapy (RAT) is a potential method to alleviate the effort of intensive, task-specific, repetitive upper limb exercises for both patients and therapists. The present study aims to investigate how a time matched combinatory training scheme that incorporates conventional and RAT, using H-Man, compares with conventional training toward reducing workforce demands. In a randomized control trial (NCT02188628, www.clinicaltrials.gov), 44 subacute to chronic stroke survivors with first-ever clinical stroke and predominant arm motor function deficits were recruited and randomized into two groups of 22 subjects: Robotic Therapy (RT) and Conventional Therapy (CT). Both groups received 18 sessions of 90 min; three sessions per week over 6 weeks. In each session, participants of the CT group received 90 min of 1:1 therapist-supervised conventional therapy while participants of the RT group underwent combinatory training which consisted of 60 min of minimally-supervised H-Man therapy followed by 30 min of conventional therapy. The clinical outcomes [Fugl-Meyer (FMA), Action Research Arm Test and, Grip Strength] and the quantitative measures (smoothness, time efficiency, and task error, derived from two robotic assessment tasks) were independently evaluated prior to therapy intervention (week 0), at mid-training (week 3), at the end of training (week 6), and post therapy (week 12 and 24). Significant differences within group were observed at the end of training for all clinical scales compared with baseline [mean and standard deviation of FMA score changes between baseline and week 6; RT: Δ4. 41 (3.46) and CT: Δ3. 0 (4.0); p < 0.01]. FMA gains were retained 18 weeks post-training [week 24; RT: Δ5. 38 (4.67) and week 24 CT: Δ4. 50 (5.35); p < 0.01]. The RT group clinical scores improved similarly when compared to CT group with no significant inter-group at all time points although the conventional therapy time was reduced to one third in RT group. There were no training-related adverse side effects. In conclusion, time matched combinatory training incorporating H-Man RAT produced similar outcomes compared to conventional therapy alone. Hence, this study supports a combinatory approach to improve motor function in post-stroke arm paresis. Clinical Trial Registration: www.ClinicalTrials. gov, identifier: NCT02188628.
The Self-Regulation of Conformity: Mental Contrasting With Implementation Intentions (MCII)

The self-regulation of conformity has received little attention in previous research. This is surprising because group majorities can exert social strong pressure on people, leading them to overlook the pursuit of their own goals. We investigated if self-regulation by mental contrasting with implementation intentions (MCII) can reduce people’s tendency to conform and facilitate their own goal-pursuit despite deviant majority influence. In a computer-based logical reasoning task, we exposed participants to a conformity manipulation, where we presented bogus diagrams showing the supposedly correct answers of a majority ingroup. Compared to participants who were not given a self-regulation strategy (Studies 1, 2, and 4) or who were in an active control group (Study 3), MCII helped participants to self-regulate conforming behavior in trying to solve the task and to independently solve the logical reasoning task, as indicated by increases in correct answers in the task. The findings suggest that MCII is an effective strategy to regulate people’s tendency to conform and supports them to attain their goal despite deviant majority influence.
Self-Regulated Resource Management in Emergency Remote Higher Education: Status Quo and Predictors

Because of the COVID-19 pandemic in the spring term 2020, students faced a sudden change from on-campus learning to online learning with synchronous and asynchronous online courses (emergency remote teaching). To study successfully, students not only needed to be prepared in terms of digital readiness (workspace, IT equipment, previous online learning experiences, and sharing information online), they also faced challenges that pertained to the self-regulated management of external resources (environment structuring, time management, and help-seeking). In the current study, we investigated students’ digital readiness for the sudden switch to online learning; differences between students’ intended and actual use of external resource management strategies; and the influence of students’ digital readiness on their actual use of resource management strategies. Students enrolled in a full-scale, German university (N = 662) answered two online questionnaires (before and in the middle of the term). Descriptive statistics indicated that students seemed to be ready to study online. However, repeated measures ANOVA showed that students were not able to manage their resources during the term as frequently as intended. Finally, separate regression analyses revealed that availability of workspace and IT equipment predicted the use of environment structuring strategies. Additionally, IT equipment and information sharing behavior predicted students’ help-seeking. Based on the current results, we discuss implications for the promotion of student self-regulated learning (SRL) in online emergency remote teaching based on both external resources and digital readiness.
The Association Between the 5Cs and Anxiety—Insights From Three Countries: Portugal, Slovenia, and Spain

Several of the most frequent psychological difficulties in childhood and adolescence are related to anxiety and lead to numerous short- and long-term negative outcomes in emotional, social, and academic domains. Empirical evidence consistently shows that the 5Cs (competence, caring, confidence, connection, and character) of Positive Youth Development (PYD) are positively related to adolescents’ contribution to self, family, and society as well as negatively related to risky behaviors and emotional difficulties, such as anxiety. Thus, the PYD can be one of the models that informs prevention programs. To provide contextualized, data-driven support for prevention efforts, we have analyzed the predictive value of the 5Cs for anxiety and anxiety dimensions using three different convenience youth samples from Portugal (N = 384, 46.6% female), Slovenia (N = 449, 69% females), and Spain (N = 768; 60.5% females). To assess the 5Cs, we used the same short form of the PYD scale in all samples (Geldhof et al., 2013) and different anxiety measures across samples: the Multidimensional Anxiety Scale for Children (MASC) in Portugal, the Lestvica anksioznosti za otroke in mladostnike anxiety scale (LAOM) in Slovenia and the Generalized Anxiety Disorder-7 (GAD-7) in Spain. The findings show significant associations of PYD and anxiety across all three contexts with all three different anxiety measures used. The associations vary across countries emphasizing the need to further research the role of contexts in anxiety prevention. Despite variations the results do indicate that connection is negatively associated with anxiety in all three contexts using the three anxiety measures, while confidence is a negative predictor and caring is a positive predictor of anxiety in Slovenia and Spain. Implications for practice within an educational framework for adolescents and youth are discussed, together with public policy recommendations.
Investigation of an MAA Test With Virtual Sound Synthesis

The ability to localize a sound source is very important in our daily life, specifically to analyze auditory scenes in complex acoustic environments. The concept of minimum audible angle (MAA), which is defined as the smallest detectable difference between the incident directions of two sound sources, has been widely used in the research fields of auditory perception to measure localization ability. Measuring MAAs usually involves a reference sound source and either a large number of loudspeakers or a movable sound source in order to reproduce sound sources at a large number of predefined incident directions. However, existing MAA test systems are often cumbersome because they require a large number of loudspeakers or a mechanical rail slide and thus are expensive and inconvenient to use. This study investigates a novel MAA test method using virtual sound source synthesis and avoiding the problems with traditional methods. We compare the perceptual localization acuity of sound sources in two experimental designs: using the virtual presentation and real sound sources. The virtual sound source is reproduced through a pair of loudspeakers weighted by vector-based amplitude panning (VBAP). Results show that the average measured MAA at 0° azimuth is 1.1° and the average measured MAA at 90° azimuth is 3.1° in a virtual acoustic system, meanwhile the average measured MAA at 0° azimuth is about 1.2° and the average measured MAA at 90° azimuth is 3.3° when using the real sound sources. The measurements of the two methods have no significant difference. We conclude that the proposed MAA test system is a suitable alternative to more complicated and expensive setups.
Developmental Features of Lexical Richness in English Writings by Chinese Beginner Learners

This paper reports a cross-sectional study that investigates the developmental features in second language writings by Chinese beginner learners of English by using four lexical richness measures—lexical sophistication, lexical variation, lexical density, and lexical errors—from the perspective of the language exposure hypothesis. Specifically, the study compares English compositions written by Chinese students of grade 7, grade 8, and grade 9 in terms of lexical sophistication, lexical variation, lexical density, and lexical errors. The English compositions were sampled from the Writing Corpus of Chinese Beginner Learners of English, and the sample size of the three grades remained almost the same. The analysis revealed that lexical richness in the writing samples of beginner learners is comparatively low, with beginner learners transferring lexical features of the oral register to their second language writings; furthermore, all four measures yielded significant, albeit non-linear and unevenly paced, developments across grade levels. Based on the findings, several suggestions for vocabulary teaching are provided.
Hypocoagulable Tendency on Thromboelastometry Associated With Severity and Anticoagulation Timing in Pediatric Septic Shock: A Prospective Observational Study

Objective: To identify whether coagulation profiles using thromboelastometry are associated with outcomes in pediatric septic shock. The primary outcomes were the development of disseminated intravascular coagulation (DIC) and the severity of the pediatric intensive care unit (PICU) existing scoring systems, while the secondary outcome was hospital mortality. This study aimed to contribute to current findings of the limitations of conventional tests in determining the optimal timing of anticoagulation in sepsis. Design: A prospective, observational study conducted between August 2019 and August 2020. Setting: PICU at a pediatric tertiary hospital in Hanoi, Vietnam. Patients: Fifty-five pediatric patients who met the septic shock criteria were enrolled. Measurements and Main Results: Fifty-five patients with septic shock were recruited. At the time of diagnosis, thromboelastometry revealed normocoagulability, hypercoagulability, and hypocoagulability in 29, 29, and 42% of the patients, respectively (p > 0.05); however, most patients in the overt DIC and non-survival groups progressed to hypocoagulability (82 and 64%, respectively). The overt DIC, PELOD-2 > 8, PRISM-III > 11, and non-survival group had a significant hypocoagulable tendency according to thromboelastometry parameters [prolonged clotting time (CT) and clot formation time (CFT); and reduced α-angle (α), maximum clot firmness (MCF), thrombodynamic potential index (TPI)] compared to the non-overt DIC, PELOD-2 ≤ 8, PRISM-III score ≤ 11 and survival group (p < 0.05). Conventional parameters between the normocoagulable and hypercoagulable groups were not different (p > 0.05). Hypocoagulability was characterized by lower platelet count and fibrinogen level, higher prolonged prothrombin time (PT), international normalized ratio (INR), and activated partial thromboplastin time (APTT), and higher D-dimer level than in hypercoagulability (p < 0.05). Hypocoagulable tendency on thromboelastometry had a higher hazard at a PT > 16.1 s [area under the curve (AUC) = 0.747, odds ratio (OR) = 10.5, p = 0.002], INR > 1.4 (AUC = 0.754, OR = 6.9, p = 0.001), fibrinogen <3.3 g/L (AUC = 0.728, OR = 9.9, p = 0.004), and D-dimer > 3,863 ng/mL (AUC = 0.728, OR = 6.7, p = 0.004). Conclusions: Hypocoagulable tendency using thromboelastometry is associated with the severity of septic shock. Conventional coagulation tests may fail to detect hypercoagulability, which is crucial in determining anticoagulation timing.
The Classroom Impact of Trained Special Needs Education Teachers in Selected Schools: An Evaluation Study

This study sought to find out factors that influence special needs education trained teachers’ performance in class. It was conducted between January and June 2019, involving a target population which comprised 3 government universal primary schools, with a total of 94 teachers and 2,386 learners. Study samples were selected, involving special needs education teachers (N = 73) and LwDs and OSNs (N = 30). Purposive sampling method was used to choose the required samples. A descriptive study design, involving qualitative approach was used. Open ended questionnaires and interview guides were used for collecting data on the critical role that teachers play in supporting LwDs and OSNs who experience barriers to learning under inclusive setting. One of the findings reveals that class size poses a serious challenge to teachers who are not well trained when they have LwDs and OSNs in large classes. Another finding indicates that teachers face challenges with the way the curriculum is designed—posing challenge to them on how to best handle it. It is also found that teachers face challenge to manage the average class number (teacher-learner ratio). It is also found that class room environment, resources and implementation of policies on education for LwDs and OSNs have both direct and indirect influence on the teachers’ impact in class. Basing on the findings, recommendations were made that: relevant authorities should increase support for teacher training and retraining for LwDs and OSNs. That curriculum modification should be done regularly. Classroom environments need regular improvement to be more disability friendly. Lastly, implementation of policies on disabilities and other special needs should be carried out on regular basis.

Does Health Literacy Make a Difference? Comparing the Effect of Conventional Medicine Versus Homeopathic Prescribing on Treatment Credibility and Expectancy

Objective While homeopathic remedies are often used to treat non-specific complaints such as headaches, empirical evidence suggests their treatment effect is due to the placebo effect. Low health literacy seems to be connected to higher use of complementary and alternative medicine (CAM). The aim of this study was to examine what people with occasional headaches expect from conventional medicine or homeopathic remedies and if health literacy interacts with this expectation. Methods In this experimental study, n = 582 participants with occasional headaches were randomized to read one of two vignettes, which described the prescription of either conventional medicine or a homeopathic remedy. Subsequently, the participants were asked to rate treatment credibility and expectancy with regard to their assigned vignette. Health literacy was assessed as a potential moderator. Results Participants in the conventional medicine group rated treatment credibility and expectancy higher than in the homeopathic remedy group. Moderation analysis revealed that when being offered conventional medicine, participant reports of treatment credibility and expectancy decreased with lower health literacy, while these outcomes increased with lower health literacy for homeopathic remedies. Discussion People with occasional headaches estimate the effectiveness of conventional medication properly. However, health care professionals should pay special attention to patients with low health literacy, as they might need more time and information to give their informed consent.
Understanding the Impact of Industrial Stress Conditions on Replicative Aging in Saccharomyces cerevisiae

In yeast, aging is widely understood as the decline of physiological function and the decreasing ability to adapt to environmental changes. Saccharomyces cerevisiae has become an important model organism for the investigation of these processes. Yeast is used in industrial processes (beer and wine production), and several stress conditions can influence its intracellular aging processes. The aim of this review is to summarize the current knowledge on applied stress conditions, such as osmotic pressure, primary metabolites (e.g., ethanol), low pH, oxidative stress, heat on aging indicators, age-related physiological changes, and yeast longevity. There is clear evidence that yeast cells are exposed to many stressors influencing viability and vitality, leading to an age-related shift in age distribution. Currently, there is a lack of rapid, non-invasive methods allowing the investigation of aspects of yeast aging in real time on a single-cell basis using the high-throughput approach. Methods such as micromanipulation, centrifugal elutriator, or biotinylation do not provide real-time information on age distributions in industrial processes. In contrast, innovative approaches, such as non-invasive fluorescence coupled flow cytometry intended for high-throughput measurements, could be promising for determining the replicative age of yeast cells in fermentation and its impact on industrial stress conditions.
Attitudes Surrounding Music of Patients With Anorexia Nervosa: A Survey-Based Mixed-Methods Analysis

Anorexia nervosa (AN) is one of the main eating disorders. It has the highest mortality of all psychiatric disorders, and the success rates of current therapies are not fully satisfactory. Thus, there is a need for novel interventions. We investigated the attitudes surrounding music of 41 patients with clinically-diagnosed AN as well as their thoughts on the potential therapeutic uses of music using a questionnaire of 50 questions. Free text responses were qualitatively analyzed for reoccurring themes with NVivo 12 software. Yes/no questions and questions of best fit were analyzed using the IBM SPSS Statistics version 25. The most prevalent theme was the positive effect of music. Most patients reported that listening to music evokes varying emotions in them (83%) which may be of positive or negative nature. Similarly, patients associated certain music with particular positive, but also with particular negative memories. A majority of patients stated that music helps to distract them (85%), helps with loneliness (59%) and helps them feel more connected to others (58%). This data indicates that people with AN make nonclinical use of music which seems to elicit positive as well as negative emotions and memories. Patients felt music is beneficial with regard to important aspects of AN, such as emotional problems, loneliness, and relationship difficulties. Most of them would also like to attend music therapy.
Modeling Wording Effects Does Not Help in Recovering Uncontaminated Person Scores: A Systematic Evaluation With Random Intercept Item Factor Analysis

The item wording (or keying) effect consists of logically inconsistent answers to positively and negatively worded items that tap into similar (but polarly opposite) content. Previous research has shown that this effect can be successfully modeled through the random intercept item factor analysis (RIIFA) model, as evidenced by the improvements in the model fit in comparison to models that only contain substantive factors. However, little is known regarding the capability of this model in recovering the uncontaminated person scores. To address this issue, the study analyzes the performance of the RIIFA approach across three types of wording effects proposed in the literature: carelessness, item verification difficulty, and acquiescence. In the context of unidimensional substantive models, four independent variables were manipulated, using Monte Carlo methods: type of wording effect, amount of wording effect, sample size, and test length. The results corroborated previous findings by showing that the RIIFA models were consistently able to account for the variance in the data, attaining an excellent fit regardless of the amount of bias. Conversely, the models without the RIIFA factor produced increasingly a poorer fit with greater amounts of wording effects. Surprisingly, however, the RIIFA models were not able to better estimate the uncontaminated person scores for any type of wording effect in comparison to the substantive unidimensional models. The simulation results were then corroborated with an empirical dataset, examining the relationship between learning strategies and personality with grade point average in undergraduate studies. The apparently paradoxical findings regarding the model fit and the recovery of the person scores are explained, considering the properties of the factor models examined.
