Optimization of the replication of hepatitis E virus genotype 3 in vitro.

Hepatitis E virus (HEV) is responsible for ∼20 million human infections worldwide every year. The genotypes HEV-3 and HEV-4 are zoonotic and are responsible for most of the autochthonous HEV cases in high-income countries. There are several cell culture systems that allow for propagation of different HEV genotypes in vitro. One of these systems uses human lung carcinoma cells (A549), and was further optimized for propagation of HEV-3 47832c strain. In this study, we investigated the effect of different media supplements as well as microRNA-122 (miR-122) on improving the replication of HEV-3 47832c in A549 cells. We observed that supplementation of maintenance media with 5% fetal bovine serum was sufficient for efficient replication of HEV-3, and verified the positive effect of media supplementation with Amphotericin B, MgCl2, and dimethyl sulfoxide on replication of HEV-3. We have also demonstrated that adding miR-122 mimics to the culture media does not have any significant effect on the replication of HEV-3 47832c. Herein, we detected over a 6-fold increase in HEV-3 replication in A549/D3 cells by adding all three supplements: Amphotericin B, MgCl2, and dimethyl sulfoxide to the culture media, while demonstrating that miR-122 might not play a key role in replication of HEV-3 47832c.

When does social media promote firm innovation? The moderating role of strategic flexibility

Despite a considerable body of innovation research focusing on social media, the influence of this factor on firm innovation remains uncertain. To address this research gap, we investigate how social media applications impact the exploitative and exploratory innovation of firms as well as the moderating effect of strategic flexibility in this context. We find that social media application exhibits a positive relationship with exploitative innovation and an inverted U‐shaped relationship with exploratory innovation. We also find that resource and coordination flexibility have moderating effects on the relationships between social media application and both exploitative and explorative innovation. Our study contributes to the literature by explicating the effects of social media on firm innovation and makes important and practical contributions to our understanding of how social media can be effectively used to promote innovation.

‘Trust us! we know what we are doing!’ Parent-adolescent digital conflict in Australian families

ABSTRACT Networked technologies and device use have become a significant source of conflict between parents and their children, negatively affecting family cohesion and wellbeing. Drawing on the findings of a participatory action research project which consisted of family workshops designed to discuss, and ultimately reduce, family digital conflict, this article explores the main sources of digital conflict amongst Australian families. Four main causes of digital conflict were reported by parents and their children: the amount of time that young people spend online and the subsequent displacement of other tasks considered by parents as more worthwhile; “inappropriate” content; the perceived effects of digital media use on children’s behaviour, and sibling conflict. Findings also revealed differing perspectives and knowledges about the value of digital technologies between parents and children which contributed to family conflict. The findings point towards a greater need for interventions which facilitate a more democratic approach to digital parenting, premised upon parental listening, negotiation, and mutual understanding.

Impact of media information and reinfection in a COVID-19 dynamical model: emergence of periodic orbits through Hopf bifurcation

In the current study, we investigate an SIRI compartmental model of COVID-19 incorporating the effect of social media and TV advertisements on the disease transmission of COVID-19 in the presence of reinfection. We have performed basic analysis on the model and studied the basic reproduction number R0 . The proposed model admits two disease-free equilibria and upto four endemic equilibria under certain parametric restrictions. We have performed local stability analyses via the Routh-Hurwitz criterion. Global asymptotic stability is established for the unique endemic equilibrium, when it exists, via the geometric approach. We have also scrutinized the proposed model for occurrence of the bifurcation phenomena and found that both forward and backward bifurcation transpires for a certain set of parameters. Simultaneously, the proposed model also displays saddle-node bifurcation. When R0>1 , the possibility of numerous endemic equilibria exists. These numerous equilibria exhibit oscillations through Hopf bifurcation leading to rich and complicated dynamics. The model is found to show hysteresis. Effect of levels of media and reinfection on the infected compartment is demonstrated and sensitivity analysis of influential model parameters is carried out. Data fitting is carried out to validate the proposed model by comparison of real data in India and the proposed model. Lastly, numerical simulations are executed for several examples to provide analytical and epidemiological understanding into model behaviour.

The effects of VAR interventions on self-rated mental fatigue and self-rated performance of football referees

ABSTRACT Football referees are required to make numerous decisions per match under physiological and emotional strain. Within this context, VAR (video assistant referee) interventions represent a key match event in which referees’ critical decisions are challenged and thus their perceived ability to control the match might also be obscured. In this study, we investigated the effects of a VAR intervention on referees’ self-rated mental fatigue (MF) and performance. Nine elite referees completed over 2–6 real matches each (total of 44 matches) a single item of MF before the match, at half-time, and immediately after the match. Situational and performance indices were also collected. The referees’ level of MF significantly increased from pre-match to half-time to post-match, yet the referees were not completely mentally fatigued at the end of the matches. Post-match MF was higher (a medium effect) for matches with a VAR intervention (n = 9) compared with matches without an intervention (n = 35). Post-match MF correlated negatively with self-rated performance, r(44) = .35, p = .019. These findings are discussed in relation to current theory and research in the area of self-control and MF in sports. We also provide recommendations for referee training and match preparation.

Simulation on the effect of filling porous medium on the performance of thermally conductive plastic heat sinks

High thermally conductive plastics have the characteristics of corrosion resistance, easy processing, and high thermal conductivity and can be used in corrosive environments or complex-shaped heat sinks. However, its thermal conductivity is still significantly lower than that of traditional metal heat sinks. Therefore, it is necessary to optimize the heat dissipation performance design. Based on the N–S equation and the k-ε turbulence model, the effect of porous media filled in the thermally conductive plastic heat sinks on its heat dissipation performance is studied. We compared this optimizing method with adding vortex generators in the literature. The maximum temperature of the heat sink bottom decreases by 9.3 °C. The pressure drop reduces by 55 %, and the Nusselt number increases by 9.3 %. The optimized heat sink has a hydrothermal performance factor (HTPF) 1.41. The heat dissipation performance can be similar to that of an aluminum heat sink. This study provides optimization ideas for expanding the application of thermally conductive plastics in heat sinks.

Development of Flash Cards to Help Write Short Stories for 5th Grade Elementary Students

This study investigates the effectiveness of "ALICE" Flash Cards as a learning medium to assist 5th-grade students in writing short stories. Recognizing the importance of writing in fostering creativity and critical thinking, the research addresses the challenges faced by students at SDN Sidorejo Lor 03 Salatiga, such as difficulties in developing themes, plots, and organizing sentences. The study employs a Research and Development (RnD) approach, integrating Sugiyono's methodology with the ADDIE model, encompassing analysis, design, development, implementation, and evaluation phases. Initial needs analysis through teacher and student questionnaires identified a lack of engaging media for writing instruction. Consequently, "ALICE" Flash Cards were designed, incorporating theme, plot, and setting cards to guide story development. Expert validation rated the media as highly suitable, leading to revisions that included simplifying instructions and adding story examples. Field testing involved pre-tests, media treatments, and post-tests. Small group trials indicated high practicality with an 80/100 score, while the effectiveness was rated 78/100 based on students' writing performance. Evaluations from students and teachers confirmed the media's effectiveness, with scores of 75/100 and 84/100, respectively. Statistical analysis using the Wilcoxon Signed Ranks Test showed a significant improvement in students' writing abilities, with a p-value < 0.05, confirming the media's positive impact. In conclusion, "ALICE" Flash Cards proved to be a highly effective educational tool, significantly enhancing 5th-grade students' ability to write short stories. This research recommends their use as a practical and engaging aid in elementary writing instruction.

Determinants of Pilots’ Performance: Investigating Technology Trust and Situation Awareness

Simulation devices have been used in aviation training for decades, probably more than in other industries. Embarking on this study, we aim to understand the relationship between the information quality provided by the information system (simulator) to pilots with the effect on situation awareness and trust in technology. Also, we aim to understand how experienced pilots with total flight and simulator hours affect their situation awareness. Furthermore, the study introduces a novel theoretical model to explore how situation awareness and trust in technology jointly impact individual pilot performance. We used structured equation modeling within the data retrieved from a survey of 233 pilots. Our results show a large effect on individual pilot performance in a simulator between situation awareness and information quality. Also, the impact on trust in technology is supported with a large effect by information quality. There is a medium effect between information quality and situation awareness, with the experience shown by pilots having a small effect on situation awareness.

Efficacy of physiotherapy treatment in medium and long term in adults with fibromyalgia: an umbrella of systematic reviews.

To summarise the available evidence and assess the effectiveness of medium and long-term physiotherapy treatment in adults with fibromyalgia (FM). This systematic review was registered in PROSPERO: CRD42023388356. The databases searched were MEDLINE, PEDro, Scopus, Cinhal, LatinIndex, and Cochrane, using the following keywords: "fibromyalgia", "physiotherapy", "treatment", "therapeutic exercise", "TENS", "laser therapy" and "manual therapy." The included articles analysed treatments with active or passive physiotherapy approaches in patients with FM. The variables included structural characteristics, such as: author, publication year, research question, and main outcome variables. The data on the findings of the articles comprised the following aspects: number of participants, intervention, follow-up, results, and principal conclusions. Thirty-three articles were analysed, with an overall PRISMA score of 18.63±3.36. The active treatment methods analysed were: movement and body awareness therapies (stretching, tai chi, yoga and Pilates); hydrotherapy; physical or aerobic exercise; and multidisciplinary therapy. The passive therapies analysed were: manual therapy; repetitive transcranial magnetic stimulation (rTMS); and other therapies (hyperbaric oxygen therapy, vibration therapy, virtual reality, transcutaneous electric nervous stimulation (TENS), pain neuroscience education, and acupuncture). Evidence was found on the positive effect of physiotherapy treatment on the signs and symptoms of fibromyalgia, such as pain, impairment of physical capacity and worse quality of life. The effectiveness of the active and passive therapies analysed in the management of the symptoms and signs of the disease was positive in most of the studies. However, more specific descriptions of the treatment protocol, frequency, intensity and treatment dose are required to reach a consensus, as well as primary studies for a more extended follow-up period to better evaluate long-term effects.

Cannabis as a shareable commodity in a social discounting task.

Cannabis use and cannabis use disorder diagnoses continue to increase in United States college-aged students as more states legalize recreational cannabis. Previous studies have attempted to associate cannabis use with delay discount rates, which involves participants making choices for smaller sooner versus larger later hypothetical rewards. More smaller sooner choices result in higher discount rates and suggest increased impulsivity. Delay discounting studies have shown a significant, but small effect size with people who use cannabis more likely to choose the smaller sooner rewards, relative to people who do not use cannabis. The present study tested whether students with different experience using cannabis (people who currently use cannabis, people who formerly used cannabis, or people who never used cannabis) would be sensitive to sharing a proportion of hypothetical marijuana with another individual at a given social distance, as a putative measure for cannabis value. Results from two separate data sets showed that students classified as current cannabis users were significantly less likely to share a proportion of hypothetical marijuana across a range of social distances, relative to students that self-reported never using cannabis. Students classified as either former or current users were not statistically different. These results were consistent with previous delay discounting results and showed a medium effect size (η² ≥ 0.10) for each data set, both separately and when combined. These results indicate that social distance is a meaningful variable that can be used in a modified discounting task to assess differential cannabis value in a student population who are increasingly susceptible to cannabis use disorder. These results may have future clinical implications. Social discount rates for cannabis may be able to differentiate individuals who will continue recreational use versus individuals that may develop cannabis dependence problems.

Validity and reliability of the Violence Risk Scale-Sexual Offense version in a community sexual offense outpatient setting.

The present study examined the convergent, structural, and predictive properties of Violence Risk Scale-Sexual Offense version (VRS-SO) scores in a sample of 200 men on community supervision for sexual offenses, attending forensic community outpatient services and followed up an average 8.6 years. The VRS-SO and two additional dynamic sexual recidivism risk measures-STABLE 2007 and Sex Offender Treatment Intervention and Progress Scale (SOTIPS)-were coded archivally from clinic files; Static-99R ratings were extracted. Recidivism data were captured from Royal Canadian Mounted Police records. VRS-SO static, dynamic, and total scores demonstrated expected patterns of convergence with total and subscale scores of the risk measures. Moreover, a confirmatory factor analysis of the VRS-SO dynamic item scores demonstrated acceptable model fit for a correlated three-factor solution consistent with prior confirmatory factor analyses. Discrimination analyses demonstrated that VRS-SO dynamic and total scores and STABLE 2007 scores had large prediction effects for 5-year sexual recidivism (area under the curves [AUCs] = .71-.72) while SOTIPS had a medium effect for this outcome (AUC = .67); the measures yielded medium to large effects for nonsexual recidivism. Cox regression survival analyses demonstrated that VRS-SO dynamic, Sexual Deviance factor, and SOTIPS scores each incrementally predicted sexual recidivism controlling for Static-99R or VRS-SO static factor scores. VRS-SO calibration analyses demonstrated that expected or predicted 5-year sexual recidivism rates showed generally close correspondence to the rates predicted or observed in the present community sample. Results support the psychometric properties of the VRS-SO, a sexual violence risk assessment and treatment planning measure, to a community outpatient sample.

Integrating electrochemically-assisted anaerobic reactors with conductive media for enhanced methanation of greywater

The utilization of bioelectrochemical systems is critical for the generation of methane via anaerobic digestion, and the process is influenced by the applied potential. The trajectory of biogas generation in five batch reactors showed important implications for methane production by synergistic effects of electric fields and conductive media allowing for attached growth of microorganisms. Synthetic greywater which is effective water source converts into methane within 5 days of reactor operation. The experiments emphasized that substrate availability enhanced the attached growth of microorganism in anaerobic settings. Reactor R2, with no microorganism-growing surface, produced only 20 % of the methane produced by reactor R3, which contained Polyvinylidene fluoride (PVDF) media. The presence of current (0.5 V) increased CH4 by 1.35 times in case of non-conductive media (R3) and 1.6 times in conductive media higher than without external voltage. The study indicated a direct correlation between applied voltage and methane generation up to 1.0 V. The ratio of CO2/CH4 changed from 1.16 at 0 V (R1) to 0.362, 0.32, 0.267 and 0.296 for R2-R5 at 1.0 V, respectively. Regardless of surface conductivity, the presence of media for attached microbial growth was favorable for the slow growing methanogens. However, high throughput RNA sequencing showed that electrotrophic methanogens were more abundant with conductive media than non-conductive media under electric fields.

Development and Validation of a Functional Health Literacy Survey for School Gardening

ABSTRACT Background Health literacy research in school gardening is lacking. Development of a psychometrically sound survey can fill this gap. Purpose The purpose of this study was twofold: 1) to develop and validate a Functional Health Literacy Survey for School Gardening (FHLS-SG), and 2) to determine the effect of health literacy on reciprocal determinism between the individual, environmental, and behavioral factors of school gardening. Methods 651 children in grades K-4 took the FHLS-SG with 31 questions about gardening and health literacy aligned to social cognitive theory. Results Cronbach’s alpha for 6 factors ranging from 0.69 to 0.84, and test-retest reliability ranging from 0.59 to 0.81 were statistically significant. Health literacy showed a small mediation effect (M) between vegetable eating behavior and the individual (M = 0.27) and vegetable eating behavior and the garden environment (M = 0.22). Health literacy had the strongest mediation effect (M = 0.36) between the garden environment and the individual. Discussion When classroom environment was used as a covariate, health literacy mediated all relationships between the individual, environmental, and behavioral factors with small to medium effects (p < .01). Translation to Health Education Practice Reciprocal determinism between individual, behavioral, and environmental factors was supported. Health literacy mediated all relationships with small to medium effects. The FHLS-SG can assess the mediating effect of health literacy on vegetable eating behavior within school garden environments.
