Feasibility and potential effectiveness of nurse-led video-coaching interventions for childhood, adolescent, and young adult cancer survivors: the REVIVER study

BackgroundChildhood, adolescent, and young adult (CAYA) cancer survivors, at risk for late effects, including cancer-related fatigue, cardiovascular issues, and psychosocial challenges, may benefit from interventions stimulating behaviour adjustments. Three nurse-led eHealth interventions (REVIVER) delivered via video calls and elaborating on person-centred care, cognitive behaviour therapy and/or motivational interviewing were developed. These interventions target: 1) fatigue management, 2) healthier lifestyle behaviours, and 3) self-efficacy and self-management. This study aimed to assess the feasibility and potential effectiveness of the REVIVER interventions for CAYA cancer survivors and healthcare professionals.MethodsIn a single-group mixed methods design, CAYA cancer survivors aged 16–54, more than five years post-treatment, were enrolled. Feasibility, assessed via Bowen's outcomes for feasibility studies, included acceptability, practicality, integration and implementation, demand and adherence. Qualitative data from semi-structured interviews and a focus group interview with survivors and healthcare professionals supplemented the evaluation. Paired sample t-tests assessed changes in self-reported quality of life, fatigue, lifestyle, self-management, and self-efficacy at baseline (T0), post-intervention (T1), and 6-month follow-up (T2).ResultsThe interventions and video consults were generally acceptable, practical, and successfully integrated and implemented. Success factors included the nurse consultant (i.e., communication, approach, and attitude) and the personalised approach. Barriers included sustainability concerns, technical issues, and short intervention duration. Regarding demand, 71.4%, 65.4%, and 100% of eligible CAYA cancer survivors engaged in the fatigue (N = 15), lifestyle (N = 17) and empowerment (N = 3) intervention, respectively, with 5, 5 and 2 participants interviewed, correspondingly. Low interest (demand) in the empowerment intervention (N = 3) and dropout rates of one-third for both fatigue and empowerment interventions were noted (adherence). Improvements in quality of life, fatigue (fatigue intervention), lifestyle (lifestyle intervention), self-efficacy, and self-management were evident among survivors who completed the fatigue and lifestyle interventions, with medium and large effect sizes observed immediately after the intervention and six months post-intervention.ConclusionsOur study demonstrates the feasibility of nurse-led video coaching (REVIVER interventions) despite lower demand for the empowerment intervention and lower adherence to the fatigue and empowerment interventions. The medium and high effect sizes found for those who completed the interventions hold potential clinical significance for future studies investigating the effectiveness of the REVIVER interventions.

Protonation Effects on the Benzoxazine Formation Pathways and Products Distribution

The effect of acidic media on the formation of the 3,4‐dihydro‐2H‐3‐phenyl‐1,3‐benzoxazine Bz is evaluated, focusing on the differentiation of intermediates and products formed by the distinct pathways observed in the presence and absence of acid. The use of real‐time mass spectrometry (PSI‐ESI‐MS) coupled to tandem MS and infrared multiple photon dissociation (IRMPD) allowed the differentiation of the species observed during the synthesis of benzoxazines in these different conditions. The results suggest that formic acid promotes the formation of aniline and phenol condensation products (IC and IIC) by protecting the aniline amino group and enhancing the formaldehyde electrophilicity. The results also suggest that although the presence of acid allow a more efficient potential energy landscape to be accessed, the last cyclization step for the formation of benzoxazines cannot be mediated by the protonation route intermediate (ROP Bz). Overall, the conclusions presented here provide important information about the synthesis of benzoxazines under acidic conditions, allowing the development of optimal reaction conditions.

There are differences in the average values before and after the film intervention, and there is a difference between the average intervention group and the control group.

Tert‐Butyl as a Functional Group: Non‐Directed Catalytic Hydroxylation of Sterically Congested Primary C−H Bonds

AbstractThe tert‐butyl group is a common aliphatic motif extensively employed to implement steric congestion and conformational rigidity in organic and organometallic molecules. Because of the combination of a high bond dissociation energy (~100 kcal mol−1) and limited accessibility, in the absence of directing groups, neither radical nor organometallic approaches are effective for the chemical modification of tert‐butyl C−H bonds. Herein we overcome these limits by employing a highly electrophilic manganese catalyst, [Mn(CF3bpeb)(OTf)2], that operates in the strong hydrogen bond donor solvent nonafluoro‐tert‐butyl alcohol (NFTBA) and catalytically activates hydrogen peroxide to generate a powerful manganese‐oxo species that effectively oxidizes tert‐butyl C−H bonds. Leveraging on the interplay of steric, electronic, medium and torsional effects, site‐selective and product chemoselective hydroxylation of the tert‐butyl group is accomplished with broad reaction scope, delivering primary alcohols as largely dominant products in preparative yields. Late‐stage hydroxylation at tert‐butyl sites is demonstrated on 6 densely functionalized molecules of pharmaceutical interest. This work uncovers a novel disconnection approach, harnessing tert‐butyl as a potential functional group in strategic synthetic planning for complex molecular architectures.

The Effectiveness of Virtual Reality Media on Primary School Students' Learning Outcomes

The development of technology today has not been fully followed by various fields of human life, one of which is the world of education. There are still problems faced such as low student learning outcomes, this factor is due to some teachers not fully utilizing technology in the learning process. This study aims to analyze the effectiveness of virtual reality media on the learning outcomes of elementary school students. The type of research used in this study is quantitative with experimental methods. The type of experimental research used in this research is a Pre-Experimental Design with One-Group Pretest-Post-test type. The data collection techniques used were observation, tests, and documentation. The data analysis technique used was descriptive analysis and prerequisite test analysis. The results of this study obtained Pretest scores with an average score of 65.07. Then obtained an average Post-test of 86.03. From the results of the T-test conducted, significant results were obtained. This is evidenced by the Sig. (2- 2-tailed) of 0.000, where the Sig. value is <0.05, so Ha is accepted and Ho is rejected Based on the results obtained, it can be concluded that virtual reality media is effective on student learning outcomes.

Learning about science topics of social relevance using lower and higher autonomy-supportive scaffolds

Evaluation of plausible alternative explanations of scientific phenomena is an authentic scientific activity. Instructional scaffolding can facilitate students’ engagement in such evaluations by facilitating their reflections on how well various lines of scientific evidence support alternative explanations. In the present study, we examined two forms of such scaffolding, with one form providing more autonomy support than the other, to determine whether any differential effects existed between the two. Nearly 300 adolescent students in middle school, high school, and university courses completed two activities on scientific topics of social relevance (e.g., the climate crisis, fossils and fossil fuel use, water resources, and astronomical origins), with the less autonomy-supportive form being completed prior to the more autonomy-supportive form. In line with prior pilot studies, both scaffold types demonstrated significant pre- to post-instructional shifts in plausibility judgments toward the scientific model and gains in knowledge with small to medium effect sizes. A mediation model provided a robust replication of previous findings showing that the indirect path meaningfully linked greater levels of evaluation to more scientific plausibility judgments and topic knowledge, above and beyond the direct relational path linking greater levels of evaluation to topic knowledge. However, we found no difference in relations between the two scaffold types, counter to our hypothesis that the more autonomy-supportive version would lead to better outcomes. This suggests that the implementation of more autonomy-supportive learning environments may be conditional, opening up a promising avenue for additional research, such as looking at specific contexts and how activities could be sequenced to optimize learning.

Examining the Effectiveness of Social Media for the Dissemination of Research Evidence for Health and Social Care Practitioners: Systematic Review and Meta-Analysis.

Social media use has potential to facilitate the rapid dissemination of research evidence to busy health and social care practitioners. This study aims to quantitatively synthesize evidence of the between- and within-group effectiveness of social media for dissemination of research evidence to health and social care practitioners. It also compared effectiveness between different social media platforms, formats, and strategies. We searched electronic databases for articles in English that were published between January 1, 2010, and January 10, 2023, and that evaluated social media interventions for disseminating research evidence to qualified, postregistration health and social care practitioners in measures of reach, engagement, direct dissemination, or impact. Screening, data extraction, and risk of bias assessments were carried out by at least 2 independent reviewers. Meta-analyses of standardized pooled effects were carried out for between- and within-group effectiveness of social media and comparisons between platforms, formats, and strategies. Certainty of evidence for outcomes was assessed using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) framework. In total, 50 mixed-quality articles that were heterogeneous in design and outcome were included (n=9, 18% were randomized controlled trials [RCTs]). Reach (measured in number of practitioners, impressions, or post views) was reported in 26 studies. Engagement (measured in likes or post interactions) was evaluated in 21 studies. Direct dissemination (measured in link clicks, article views, downloads, or altmetric attention score) was analyzed in 23 studies (8 RCTs). Impact (measured in citations or measures of thinking and practice) was reported in 13 studies. Included studies almost universally indicated effects in favor of social media interventions, although effect sizes varied. Cumulative evidence indicated moderate certainty of large and moderate between-group effects of social media interventions on direct dissemination (standardized mean difference [SMD] 0.88; P=.02) and impact (SMD 0.76; P<.001). After social media interventions, cumulative evidence showed moderate certainty of large within-group effects on reach (SMD 1.99; P<.001), engagement (SMD 3.74; P<.001), and direct dissemination (SMD 0.82; P=.004) and low certainty of a small within-group effect on impacting thinking or practice (SMD 0.45; P=.02). There was also evidence for the effectiveness of using multiple social media platforms (including Twitter, subsequently rebranded X; and Facebook), images (particularly infographics), and intensive social media strategies with frequent, daily posts and involving influential others. No included studies tested the dissemination of research evidence to social care practitioners. Social media was effective for disseminating research evidence to health care practitioners. More intense social media campaigns using specific platforms, formats, and strategies may be more effective than less intense interventions. Implications include recommendations for effective dissemination of research evidence to health care practitioners and further RCTs in this field, particularly investigating the dissemination of social care research.

Entrepreneurship in the Age of Social Media

Abstract Social media is ubiquitous and continuously evolving. This study investigates the impact of social media on the intention toward entrepreneurship/self-employment. Further, we explore the moderating effect of social media on the relationships between women, self-efficacy and leisure activities on intention toward entrepreneurship/self-employment using a survey-based dataset. We find that the ability to take advantage of social media within an entrepreneurial context does not necessarily mean that an individual is propelled towards entrepreneurship, however proactive individuals are able to exhibit this characteristic, as are creative women. A counter-intuitive finding is that entrepreneurship and conventional organizational employment choices are not mutually exclusive. While risk aversion inhibits entrepreneurship as expected, contextual conditions such as being married or being employed affects men and women differently.

Research on the Effects of Media on Womens Entrepreneurship

The media is a powerful tool for shaping public opinion and can significantly influence women's entrepreneurial decisions. By portraying women entrepreneurs in a positive and egalitarian light, the media can help eliminate the negative effects of gender bias, thereby enhancing society's perception and evaluation of women entrepreneurs. Therefore, examining the impact of modern media on women entrepreneurs in contemporary society is a complex and significant issue. Focusing on the growing importance of this topic, the paper aims to explore the impact of media coverage on the image and status of women entrepreneurs. The impact is identified through questionnaires, in-depth interviews, and media content analysis. It conducts an online questionnaire survey and in-depth interviews with 300 women entrepreneurs and 20 women entrepreneurs from different industries. The results showes that over 65% of the respondents believed that media bias had a negative impact on their entrepreneurial spirit, and almost 70% felt that their businesses did not receive fair coverage. The findings confirm that the medias gendered portrayal of women entrepreneurs affects not only public perceptions of their capabilities and potential but also challenges their confidence and willingness to start their own businesses.

Synergist enhancement of effective desilication of graphite ore by rotary triboelectric separation and surface modification

Desilication of graphite ores helps to ensure their high-value applications. Surface modification and triboelectric separation methods were used to improve the desilication of graphite ore. Effects of friction media and chemicals on the charge properties of graphite and quartz were investigated by charge-to-mass ratio tests and the adsorption mechanism was analyzed. Furthermore, effects of electrode voltage and rotational speed on the desilication of graphite ore were investigated. The results showed that polyvinyl chloride was the best friction medium for graphite and quartz, and the charging effect of kerosene-modified graphite and quartz was better than that of ethanol. Kerosene modification made graphite more positively charged and quartz more negatively charged, enlarging the charge-to-mass ratio gap. Desilication efficiencies of 0.25–0.5 mm, 0.125–0.25 mm, and 0.074–0.125 mm graphite ores after kerosene modification were 42.27% (20.20% increase), 48.92% (17.18% increase), and 57.26% (19.92% increase), respectively. Our study provides guidance for the purification of graphite.

QUANTUM DISCORD AND ENTANGLEMENT FOR TWO ATOMS IN A KERR MEDIUM AND STARK SHIFT

. This study analyzes the effect of the Kerr medium and Stark shift on the entanglement between two two-level atoms and a single-mode cavity in a quantum model. The findings demonstrate that the entanglement between the atoms varies periodically over time, with the periods affected by the Kerr medium and Stark shift. The Kerr medium and Stark shift hinder atom disentanglement, resulting in a prolonged stationary entangled state. The Stark shift can also enhance atom-atom entanglement for partially entangled states. These findings reveal that the Kerr medium and Stark shift can effectively control the entanglement between two atoms. Moreover, weak measurement strength impacts quantum particles' entanglement, which decreases over time. Quantum discord is more affected by weak measurement strengths than entanglement, decreasing until a critical point and increasing with a further rise in weak measurement strengths.

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.
