Background: Strategies to implement evidence-based interventions (EBIs) in children’s mental health services have complex direct and indirect causal impacts on multiple outcomes. Ripple effects are outcomes that are caused by EBI implementation efforts and are unplanned, unanticipated, and/or more salient to stakeholders other than to researchers and implementers. The purpose of the current paper is to provide a compilation of possible ripple effects associated with EBI implementation strategies in children’s mental health services, to be used for treatment development, implementation planning, research, and quality improvement. Methods: Participants were identified via expert nomination and snowball sampling. Online surveys were completed by 81 participants who contributed ripple effects, each representing one of five roles: providers of mental health services to children or youth, researchers, policy makers, caregivers, and youth. A partially directed conventional content analysis with consensus decision making was used to code ripple effects. Results: Four hundred and four unique responses were coded into 66 ripple effects and 14 categories. Example categories include general knowledge, skills, attitudes, and confidence about using EBIs; general job-related ripple effects; EBI treatment adherence, fidelity, and alignment; gaming the system; equity and stigma; shifting roles, role clarity, and task shifting; economic costs and benefits; EBI treatment availability, access, participation, attendance, barriers, and facilitators; clinical process and treatment quality; client engagement, therapeutic alliance, and client satisfaction; clinical organization structure, relationships in the organization, process, and functioning; youth client and caregiver outcomes; and use of EBI strategies and insights in one’s own life. Conclusions: This research advances the field by providing children’s mental health implementers, researchers, funders, policy makers, and consumers with a menu of potential ripple effects for consideration when evaluating implementation quality and impact. It can be a practical tool to ensure compliance with the guidance of experts from Quality Improvement/Quality Assurance, Complexity Science, Diffusion of Innovation Theory, and the Medical Research Council. Future phases will match potential ripple effects with the most salient children’s mental health implementation strategies for each participant role. Trial Registration: None.

Authors: Zhang Xiuzai , Tan Xin , Zhai Mengsi , Zhou Lijuan
Published: February 2022

Soot aerosol is an important part of atmospheric aerosol, which has important influence on the propagation of quantum signal. In order to study the influence of soot aerosol on satellite-ground quantum communication, according to the size distribution parameter and extinction coefficient of the soot aerosol, the influence of the concentration of the soot aerosol particles and the transmission distance on the attenuation of the link is analyzed. The simulation experiments of channel capacity, channel fidelity and channel bit error rate (Ber) are carried out with amplitude-damped channel. The simulation results show that the soot aerosol concentration increases from 2.1×10 6 / m 3 to 3.2 10× 6 / m 3 , the link attenuation factor increases from 0.3dB/ km to 0.46dB/ km, the fidelity decreases from 0.98 to 0.97, and the bit error rate increases from 0.0087 to 0.0122 at a transmission distance of 3km . hhen the transmission distance is 6km and the particle concentration is 2.1×10 6 / m 3 , 2.7 10× 6 / m 3 and 3.9×10 6 / m 3 , the channel capacity increases from 1.078 to 1.0809, and then decreases to 1.0804. Therefore, the soot aerosol has influence on the performance of satellite-ground quantum communication, and the degree of influence is different. In order to ensure the reliability of quantum communication between satellite and ground, the parameters can be adjusted to ensure the normal transmission of quantum signal.

Published: February 2022

Cellulose nanocrystals were successfully extracted from caroá (Neoglaziovia variegata) and macambira (Bromelia laciniosa) fibers, which are native plants from the semi-arid Caatinga biome in Northeastern Brazil. Fibers were submitted to alkaline and bleaching treatments prior to sulfuric acid extraction. Morphology and chemical composition (holocellulose and cellulose content) of fibers were determined by scanning electron microscopy and chemical analysis, respectively. Cellulose nanocrystal structure, crystallinity and thermal stability were determined respectively by atomic force microscopy and thermogravimetric analysis. Results show that mercerization followed by bleaching were able to remove waxes and amorphous regions. Caroá fibers required one mercerization and three bleaching steps while macambira needed one mercerization and two bleaching steps prior to nanocrystal extraction. Alkaline treated and bleached samples had lower thermal stability as compared to untreated fibers due to removal of lignin and increased surface area. Caroá and macambira are renewable sources of cellulose nanocrystals with potential applications as reinforcements to nanocomposites.

Authors: Ezarfelix Juandreas , Jeffrey Nathannael , Sari Novita
Published: February 2022

The popularity of social media continues to grow, and its dominance of the entire world has become one of the aspects of modern life that cannot be ignored. The rapid growth of social media has resulted in the emergence of ecosystem problems. Hate speech, fraud, fake news, and a slew of other issues are becoming un-stoppable. With over 1.7 billion fake accounts on social media, the losses have al-ready been significant, and removing these accounts will take a long time. Due to the growing number of Instagram users, the need for identifying fake accounts on social media, specifically in Instagram, is increasing. Because this process takes a long time if done manually by humans, we can now use machine learning to identify fake accounts thanks to the rapid development of machine learning. We can detect fake accounts on Instagram using machine learning by implementing the combination of image detection and natural language processing.

Authors: Wang Xianqiang , Liu Duo , Zhang Jiandong , Jiao Yubo
Published: February 2022

In order to accurately simulate structural fatigue crack damage, the non-linear contact model was selected and verified to be suitable for the fatigue crack simulation in cantilever beam. The influence of damage severity and location on harmonic vibration responses were revealed. Moreover, the damage identification indexes based on harmonic excitation response were constructed, and the effectiveness used to identify fatigue crack damage was validated. The results reveal that contact model is effective in simulating fatigue crack and sensitive to nonlinear fatigue crack through the comparative analysis of harmonic vibration response of intact structure and damaged one. For the vibration responses of beam with different damage severities and locations, the greater the damage severity is, and the closer the damage location is to the fixed end, the more obvious the non-linear vibration characteristics presents. Two damage indicators including distortion value of phase spectrum (h∆) and proportion of super/sub-harmonic amplitudes (Dd) are applied, which can effectively characterize the change of fatigue crack with different damage location and severity. Furthermore, contact model presents stronger non-linear information compared with bilinear model, which is more suitable for fatigue damage simulation.

Authors: Zhou Xintao , Cui Yahui
Published: February 2022

The complexity of single-loop gear system transmission structure makes it difficult for traditional modeling methods to establish precise dynamic model, which greatly affects the accuracy of its dynamic characteristics research. Firstly, a structure diagram is established by adopting modularization idea according to the structural properties of single-loop gear system. On this basis, a precise bond graph model of the single-loop gear system is obtained combining the modeling principle of bond graph method and the advantages of rich graphics library. Secondly, the dynamic state equation of single-loop gear system is obtained from bond graph model. The simulation model of gear system is established by numerical simulation method. Eventually, the dynamic characteristics of a single-loop gear system are acquired by calculating two dynamic indexes of the system under linear and weakly nonlinear states. The simulation results show that the bond graph method can accurately describe the mathematical model of single-loop gear train and master the dynamic characteristics of complex gear train. This will provide a reference for the structural design and dynamic characteristics of the transmission system.

Published: February 2022

One of the major challenges faced by water companies around the world is the high level of chlorine losses in distribution networks. This paper presents an experimental study to examine chlorine loss in different types of pipe materials and select the ones with low chlorine demand for the rehabilitation of the water distribution network of San Pedro Nexapa, State of Mexico. The materials investigated include: polyvinyl chloride (PVC), galvanized steel (GS), polypropylene (PP) and high-density polyethylene (HDPE). A 24-h chlorine consumption study was performed in a simulated water distribution network to assess the impact of wall reaction coefficient on chlorine decay. Four sets of independent pipe loops of 50 mm in diameter and 12 m in length were used. Two different scenarios were considered based on different initial chlorine concentration (1.21 mg/L and 1.60 mg/L). Samples were collected at each loop at two-hour intervals and physicochemical analyses were conducted. Results from the experimental distribution network showed that the wall coefficient values for GS, HDPE, PP and PVC were 0.165 h−1, 0.059 h−1, 0.043 h−1 and 0.026 h−1, respectively. Experimental results showed that wall reaction coefficient values depend on initial chlorine concentration and the characteristics of pipe material. The rate of free chlorine decay was found to be faster in steel pipe and slower in the plastic pipes. Based on its having the lowest chlorine demand compared with the other pipes, PVC pipe would be selected to rehabilitate Nexapa water distribution network, State of Mexico. The wall coefficients from the experimental study were incorporated into EPANET through four simulation runs to predict chorine decay of San Pedro Nexapa water distribution network, State of Mexico. In the PVC and PP pipes higher residual chlorine concentrations were observed that ranged from 0.30 to 0.90 mg/L and 0.50 to 0.95 mg/L, respectively. This study is important for utilities to operate their system effectively and protect public health.

Role of Polysaccharides Mimetic Components in Targeted Cancer Treatment
Authors: Gupta Nandan , Malviya Rishabha
Published: February 2022

Organic or inorganic compounds are synthesized or formulated to demonstrate their thera-peutic actions, like a natural polysaccharide in the body. Polysaccharides, the major type of natural polymers, are biologically active, non-toxic, hydrophilic, and biodegradable and exhibit various prop-erties. This manuscript is focused on delivering anticancer drugs with the help of mimetic compo-nents of polysaccharides. The data presented in this manuscript were obtained from PubMed, Else-vier, Taylor & Francis and Bentham Science Journals. Most chemotherapeutics are toxic to the hu-man body, have a narrow therapeutic index, sluggish pharmaceutical delivery mechanisms, and are poorly soluble in water. The use of mimetic components of polysaccharides leads to the enhancement of the solubility of drugs in the biological environment. The current review summarizes the use of mimetic components of polysaccharides along with anticancer agents, which are capable of inhibiting the growth of cancerous cells in the body and exhibiting lesser adverse effects in the biological sys-tem compared to other therapies.

Published: February 2022

Background:

Receptor-interacting serine-threonine protein kinase 3 (RIP3) was previously
discovered to be an important medium in the occurrence and development of major atherosclerotic
cerebral infarction. However, the role of RIP3 in acute ischemic stroke remains unclear.

Objective:

This study aimed to explore the correlation between plasma levels of RIP3 and acute
ischemic stroke with large-artery atherosclerosis (LAA).

Methods:

This prospective study enrolled 116 patients with LAA, 40 healthy controls, and 30 acute
ischemic stroke patients with small-artery occlusion. The patients with LAA were divided according
to the quartile of plasma levels of RIP3. A logistic regression model was used for comparison. The
ROC curve was performed to evaluate the predictive value.

Results:

In patients with LAA, the RIP3 levels in patients with poor outcomes as well as neurological
deterioration were significantly higher than those with good outcomes (P < 0.001) and without
neurological deterioration (P = 0.014). Patients in the highest levels of plasma RIP3 quartile were
more likely to have neurological deterioration (OR, 11.07; 95% CI, 1.990-61.582) and poor outcomes
(OR, 35.970; 95% CI, 5.392-239.980) compared with the lowest. The optimal cut-off value
for neurological deterioration was 1127.75 pg/mL (specificity, 66.7%; sensitivity, 69.2%) and that
for poor prognosis was 1181.82 pg/mL (specificity, 89.7%; sensitivity, 62.1%).

Conclusion:

Elevated levels of plasma RIP3 were significantly associated with neurological deterioration
and poor prognosis in patients with LAA. A significant increase in plasma RIP3 levels can
predict neurological deterioration and the poor prognosis of these patients.

Published: February 2022

Viral infections can cause fatal illnesses to humans as well as animals. Early
detection of viruses is therefore crucial to provide effective treatment to patients. Recently,
the Covid-19 pandemic has undoubtedly given an alarming call to develop rapid and
sensitive detection platforms. The viral diagnostic tools need to be fast, affordable, and
easy to operate with high sensitivity and specificity equivalent or superior to the currently
used diagnostic methods. The present detection methods include direct detection of viral
antigens or measuring the response of antibodies to viral infections. However, the sensitivity
and quantification of the virus are still a significant challenge. Detection tools employing
synthetic binding molecules like aptamers may provide several advantages over
the conventional methods that use antibodies in the assay format. Aptamers are highly stable
and tailorable molecules and are therefore ideal for detection and chemical sensing applications.
This review article discusses various advances made in aptamer-based viral detection
platforms, including electrochemical, optical, and colorimetric methods to detect
viruses, specifically SARS-Cov-2. Considering the several advantages, aptamers could
be game-changing in designing high-throughput biosensors for viruses and other biomedical
applications in the future.

It was shown that the assumption of straight-line probing beams, which is usually used in reconstructing the plasma density profile from interferometric measurements, leads to unacceptably large errors in the case of a dense plasma. A fast method based on the assumptions of geometric optics is proposed for calculating the interferometric signal. This method takes into account the refraction of the probe wave and can be used in reconstruction of the plasma density profile. The method correctness is confirmed by comparison with the results of full-wave calculations.

The paper presents the results of scanning of mechanical properties of coniferous (common pine Pinus sylvestris) and deciduous (small-leaved lime Tilia cordata and common oak Quercus robur) trees wood using nanoindentation on crosscut face. Manifold increase in microhardness H and Young’s modulus E has been observed between early and late wood in every annual growth ring. Significant differences in intraring radial dependencies of H and E have been found among studied species. For all studied species the average values of E and H of early wood in each annual ring are found to be independent from ring width, while such dependence for late wood is weak at most. The ring widths measured by nanoindentation coincide with the ones measured by standard optical method within 2-3%. The developed technique and obtained results can be useful 1) to amend the understanding the origins of macromechanical properties of various wood species and their dependence upon microstructural characteristics and growth conditions, 2) to optimize the technologies of growing, reinforcement and subsequent usage of the wood, 3) to develop new independent high resolution methods in dendrochronology.
Smartphone Alcohol Use Disorder Recovery Apps: Cross-sectional Survey of Behavioral Intention to Use
Authors: Menon Rijuta , Meyer Julien , Nippak Pria , Begum Housne
Published: February 2022

Background

Alcohol use disorder (AUD) carries a huge health and economic cost to society. Effective interventions exist but numerous challenges limit their adoption, especially in a pandemic context. AUD recovery apps (AUDRA) have emerged as a potential complement to in-person interventions. They are easy to access and show promising results in terms of efficacy. However, they rely on individual adoption decisions and remain underused.

Objective

The aim of this survey study is to explore the beliefs that determine the intention to use AUDRA.

Methods

We conducted a cross-sectional survey study of people with AUD. We used the Unified Theory of Acceptance and Use of Technology, which predicts use and behavioral intention to use based on performance expectancy, effort expectancy, social influence, and facilitating conditions. Participants were recruited directly from 2 sources; first, respondents at addiction treatment facilities in Ontario, Canada, were contacted in person, and they filled a paper form; second, members from AUD recovery support groups on social media were contacted and invited to fill an internet-based survey. The survey was conducted between October 2019 and June 2020.

Results

The final sample comprised 159 participants (124 involved in the web-based survey and 35 in the paper-based survey) self-identifying somewhat or very much with AUD. Most participants (n=136, 85.5%) were aware of AUDRA and those participants scored higher on performance expectancy, effort expectancy, and social influence. Overall, the model explains 35.4% of the variance in the behavioral intention to use AUDRA and 11.1% of the variance in use. Social influence (P=.31), especially for women (P=.23), and effort expectancy (P=.25) were key antecedents of behavioral intention. Facilitating conditions were not significant overall but were moderated by age (P=.23), suggesting that it matters for older participants. Performance expectancy did not predict behavioral intention, which is unlike many other technologies but confirms other findings associated with mobile health (mHealth). Open-ended questions suggest that privacy concerns may significantly influence the use of AUDRA.

Conclusions

This study suggests that unlike many other technologies, the adoption of AUDRA is not mainly determined by utilitarian factors such as performance expectancy. Rather, effort expectancy and social influence play a key role in determining the intention to use AUDRA.
Considerations for a Social Media Physical Activity Program: Exploratory Study (Preprint)
Authors: Scott-Andrews Katherine Q , Lane Annalise , Rock Sarah , Robinson Leah E
Published: February 2022

BACKGROUND

Social media may be a powerful platform to combat parents’ and children’s low physical activity levels.

OBJECTIVE

This study surveyed parents’ beliefs about physical activity in order to expand the extant literature concerning the interest in and the design of an effective and feasible social media physical activity (SMPA) program.

METHODS

Primary caregivers (n=250; 215 [86%] mothers, 164 [65.6%] White) of children aged 6-12 years completed an online questionnaire. Interest was examined through responses on the questionnaire; beliefs (ie, perceptions, knowledge, and support) about physical activity were examined using Spearman correlations; and to support the SMPA program design, researchers examined a combination of multiple-choice and free-response questions. For the free-response questions, the researchers performed open coding related to perceived benefits, barriers, and motivators.

RESULTS

Parent respondents (n=215, 86%) were interested in a SMPA program tailored for families. Regarding beliefs, parents exhibited a monotonic relationship between 2 questions related to perceptions of physical activity levels in their children (rs(250)=.310, P<.001), knowledge about physical activity and motor skills (rs(250)=.328, P<.001), and support of physical activity and motor skills (rs(250)=.385, P<.001). Parents perceived benefits of a SMPA program, highlighting family time and health. Barriers included time constraints, a lack of motivation, and environmental factors.

CONCLUSIONS

Parents are interested in supporting healthy family behaviors using a SMPA program. An effective program should emphasize motor skill activities, be fun and family oriented, and incorporate incentives, goal setting, and advice and tips. SMPA also needs to address identified barriers, such as those regarding time and environment.

Published: February 2022

BACKGROUND

Mobile teledermatology is increasingly being used in clinical practice and offers the opportunity to counsel the general public about sun protection and skin cancer early detection. Growing evidence suggests that SMS text messaging interventions are an effective way to reach a large number of people and promote sun protection behaviors. Many medical practices already have SMS text message systems in place to communicate with patients, especially for appointment reminders and information. However, could we use these systems for even better outcomes? If so, how?

OBJECTIVE

This presentation will outline the results of the SunText study, a theory-based SMS text messaging intervention designed to evaluate how often and in what way we could communicate with people at risk of skin cancer to have a beneficial effect on sun protection behaviors, sunburn, and participant engagement.

METHODS

The SunText study was conducted between February-July 2019 in Queensland, Australia. Volunteer participants aged 18 to 40 years were randomized to 4 different intervention schedules using a Latin square design. The schedules included personalized or interactive messages with constant frequency and personalized and interactive messages with either increasing or decreasing frequency. Outcomes measured were reduction in sunburn and engagement with interactive messages, defined as responding to messages by return text.

RESULTS

Compared to baseline, the self-reported sun protection habits index was significantly higher in all 4 interventions (P<.01). Overall, sunburn rates decreased from baseline to the end of the intervention (40.3% to 7.0%), and remained significantly below baseline levels (23.5%) at the 6-month follow-up (P<.01). All 4 interventions achieved reductions in sunburn rates (18%-48% reduction) during the intervention period. The overall engagement rate with interactive messages was 71%. The intervention involving interactive messages with constant frequency achieved the highest engagement rate. The intervention with personalized and interactive messages with increasing frequency had the lowest engagement rate.

CONCLUSIONS

This study adds to the evidence that text messages targeting sun protection are effective in improving sun protection behaviors and reducing sunburn. Results also suggest higher engagement with constant or decreasing message frequency. Although many clinics already use SMS text messaging for scheduling, this presentation may encourage its extended use to raise awareness of sun protection. Interactive messages could also be integrated into sun protection mobile health apps, and provide an opportunity for engaging in health promotion content.

Authors: Ghose Urmee , Dhar Dr. Satyajit
Published: February 2022

Peoples are always intending to invest their savings for several security purposes, but the crucial matter of concern is that where they are investing. Thinking of such investment options, capital market is a superior alternative all the time. Panic due to lack of financial knowledge about that market acts as crucial parameter in becoming the people’s choice of investment. After went over a myriad of investment choices, mutual fund would be a secure platform to invest. The main purpose of this study is to get an overview about the financial literacy level of Bangladeshi investors who invest in mutual fund and trying to assess the implication of financial literacy on investment intension. Data were collected with the help of online survey method from primary sources on the basis of a well-structured questionnaire where convenient sampling is applicable due to focus on mutual fund investors. Respondents’ financial knowledge level is evaluated by asking eleven specific questions on varied financial concepts following the G20 survey of OECD and investment intention is measured by Ajzen’s conceptual and methodological framework. Based on the descriptive statistics, Correlation is used to analyze the collected primary data. Some significant findings are uncovered like Bangladeshi investors belong to low literacy level. Study also indicates a negligible inverse relationship between financial literacy level and investment intention of investors which in turn stimulate existing investors to recommend others to invest in mutual fund due to low literacy level. So it is profound that low literate investors can be a vital key to promote mutual fund and enrich financial market of Bangladesh.

Akram and Kumar (2018) maintained that “Children are growing up surrounded by mobile devices and interactive social networking sites such as Twitter, MySpace, and Facebook, Orkut which has made the social media a vital aspect of their life. Social network is transforming the behavior in which youthful people relate with their parents, peers, as well as how they make use of technology.” This study aimed to find out the advantages and disadvantages of social online platforms from the students’ perspectives at Quds university. The researcher distributed a questionnaire as tool of research which consists of 20 items. Moreover, the study used also a qualitative tool: two interviews with two students. The sample was 60 students of the first and second year level. The researcher concluded that there are radical positive and negative effects of social platforms on students. However, these platforms have more positive effects especially during the Covid-19 crisis. The researcher recommended raising awareness of the pros and cons of social platforms among future generations. Alternatively, the researcher recommends that a combination of face to face and social platforms will have more efficacy in language teaching and learning

Published: February 2022

This study intended to examine The Effectiveness of Guidance and Counseling Practices on Students’ Career Development in Secondary Schools in Temeke Municipality using embedded research design. It was undertaken in Temeke Municipality, Dar es Salaam Region, Tanzania. The target population was heads of secondary schools, teachers, students, and ward educational officers. The sample size used comprised of 15 teachers, equivalent to 10% of the 150 teachers in the selected secondary schools, three school heads, and 120 students as 10% of 1,200 students from Forms III and IV. Probability and non-probability sampling tactics were employed in the selection of respondents from the targeted population. Observation method, documentary review, interview guide and questionnaires were used to collect primary data while secondary data were obtained in the documents. Data were analyzed both quantitatively and qualitatively. The findings reveal the existing lack of specialized personnel in the field of career guidance and counseling. Instead, teachers are randomly picked to hold that position; a teacher seen to be morally upright and religious is appointed and tries to do the best possible to support these students. Through the study, there was glaring evidence that the tight school timetable does not give room for students to consult their teachers –particularly the time table for extra-curricular activities. It has been established, according to the survey, that guidance and counseling practices face limited teaching and learning materials, counseling offices, negative perception from students and limited support from the government. The findings also show that students experience little support from parents and teachers. Schools in the sample lacked special counseling rooms and even confidentiality from teachers. It is, thus, recommended that special in-service training and seminars should be provided to teachers expected to be school guidance-counselor and there should be financial support from parents, government and the community at large.

Objectives: To evaluate the role of uric acid in patients with MS as an investigational marker in true relapse events.

Methods: 108 patients with relapsing-remitting and Secondary progressive MS, compared to case-control of about 120 patients (manifested other neurological diseases OND) who were included in this study which was conducted from March 2008 to July 2009 at Baghdad Teaching Hospital multiple sclerosis clinic. A study protocol sheet was done and filled from the patient's database in the MS clinic.

Results: In the overall MS group, serum UA levels were lower than in controls, the difference did reach statistical significance (P=0.01). Serum UA was found to be lower in patients during relapse than when they are in remission. The mean serum UA level from patients after one month of follow up shows an inverse correlation with MS type, age, and EDSS score, and positive correlation with gender and clinical activity, but none of these correlations reach statistical significance.

Conclusions: The question whether reduced serum UA level in MS is a primary deficit or an epiphenomenon remains open. Despite the fact that UA level was lower in clinically-documented active patients, a general mean UA decrease is evident also in clinically and MRI inactive MS patients as compared to OND.
