OBJECTIVE:To update the current characteristics about the scope and quality of mixed methods research(MMR)in complementary and alternative medicine(CAM)after nearly 10 years.METHODS:A 5-stage approach for conducting a scoping review was adopted.Articles published on the top 10 journals in CAM with the highest impact factor in 2020 were screened for MMR.Information of included articles were extracted,and then synthesized to illustrate the current state.Methodological quality was evaluated according to the Mixed Method Appraisal Tool(MMAT)2018 version.RESULTS:A total of 55(55/2991,2%)articles using mixed methods were retrieved,including 17 medical studies and 38 ethnobotanical studies.We performed an in-depth analysis on the 17 medical studies,which studied cancer,stress,pain,fatigue,exercises,mindfulness intervention,herbal medicine use,art and acupuncture.Thirteen pilot studies applied MMR to evaluate the feasibility of interventions or programs(13/17,76%);phenomenology was inferred as the most common philosophical assumptions(13/17,76%);the most applied type of MMR was convergent design(16/17,94%);integration often took place at integration(12/17,71%).Among the 16 eligible studies for quality appraisal,majority were rated as good(14/16,88%),whereas two studies were rated as poorly described.Primarily,a poor rating was due to incomplete reporting of data analysis and citations in qualitative components;lack of confounder controlling and the sampling strategy in quantitative components;poor description of integration and justification for mixed methods.Comparing with the previous review,fewer MMR were published in 2020 in CAM,but the proportion of studies that clearly reported MMR has increased by 4 times(4%→15%).CONCLUSION:CAM researchers need to realize the benefits that MMR can have on conducting further health care research.Our findings highlight that applying MMR will be helpful to understand the complex dynamics and interdisciplinary nature of complex intervention.In addition,addressing a standardized reporting criteria for MMR is recommended. 展开更多

Objective:This study provides a preliminary evaluation of the usability and acceptability of a mobile application(sexual assault care algorithm,SACA).Methods:An explanatory sequential mixed methods research was used.A quantitative survey was followed up by a qualitative study.A convenience sample of participants(n=4)was recruited.The research was conducted on a one-on-one basis.In the quantitative phase,a random assignment technique was used to divide four participants into two groups of two participants each.Post-Study System Usability Questionnaire(PSSUQ)and Acceptability e-Scale were used to collect quantitative data.In the qualitative phase,interview,observation,and documentation were used to collect qualitative data.Data were analyzed both quantitative and qualitatively.The qualitative data were linked with the initial quantitative data to determine how the follow-up qualitative data helped explain the initial quantitative results.Results:The quantitative results suggested that SACA has high usability(5.05±1.83)and acceptability(3.81±1.22).The qualitative results further indicate that the participants thought SACA was easy to use and useful,and most of them would recommend it to others.Areas of improvement include adding features that would calculate and validate the elapsed time since the sexual assault,adding explanations to some buttons,and providing training.Conclusions:Our findings highlight the value of using a mixed methods research design to conduct a usability and acceptability test.Nurses are more likely to adopt a new technology for their evidencebased practice when the technology is easy to use and useful and requires less time to find the right piece of guideline evidence.Individualized training needs to be designed based on users'characteristics. 展开更多

Background To detect and identify mosquitoes using their characteristic high-pitched sound,we have developed a smartphone application,known as the‘HumBug sensor’,that records the acoustic signature of this sound,along with the time and location.This data is then sent remotely to a server where algorithms identify the species according to their distinctive acoustic signature.Whilst this system works well,a key question that remains is what mechanisms will lead to effective uptake and use of this mosquito survey tool?We addressed this question by working with local communities in rural Tanzania and providing three alternative incentives:money only,short message service(SMS)reminders and money,and SMS reminders only.We also had a control group with no incentive.Methods A multi-site,quantitative empirical study was conducted in four villages in Tanzania from April to August 2021.Consenting participants(n=148)were recruited and placed into one of the three intervention arms:monetary incentives only;SMS reminders with monetary incentives;and SMS reminders only.There was also a control group(no intervention).To test effectiveness of the mechanisms,the number of audio uploads to the server of the four trial groups on their specific dates were compared.Qualitative focus group discussions and feedback surveys were also conducted to explore participants’perspectives on their participation in the study and to capture their experiences of using the HumBug sensor.Results Qualitative data analysis revealed that for many participants(37 out of 81),the main motivation expressed was to learn more about the types of mosquitoes present in their houses.Results from the quantitative empirical study indicate that the participants in the‘control’group switched on their HumBug sensors more over the 14-week period(8 out of 14 weeks)when compared to those belonging to the‘SMS reminders and monetary incentives’trial group.These findings are statistically significant(p0.95 under a two-sided z-test),revealing that the provision of monetary incentives and sending SMS reminders did not appear to encourage greater number of audio uploads when compared to the control.Conclusions Knowledge on the presence of harmful mosquitoes was the strongest motive for local communities to collect and upload mosquito sound data via the HumBug sensor in rural Tanzania.This finding suggests that most efforts should be made to improve flow of real-time information back to the communities on types and risks associated with mosquitoes present in their houses. 展开更多

Therefore, sexual activities occur behind bars, regardless of the stringent rules in correctional institutions. However, little has been documented about risky sexual behaviors, determinants, and experiences among inmates of correctional institutions in Katsina State, Nigeria. The study determined the sexual practices, prevalence, and determinants of risky sexual behaviors among prison inmates in Katsina. Methodology: A descriptive cross-sectional design with concurrent mixed methods of data collection was used to interview 216 inmates using a semi-structured questionnaire supplemented with 22 in-depth interviews. Result: Most (94%) respondents were male, almost half (44.4%) had secondary education, more than half (55.1%) were engaged in business or trading before incarceration, and the majority (75.9%) were awaiting trial. Nearly all inmates (98.6%) reported having sexual desire. Drug use (80.1%) and unprotected sex (79.2%) were quite common but sexual violence was low (7.4%). The number of sexual partners of respondents remained a significant predictor of sexual activity. Inmates who had one (1) or no sexual partner were 64% less likely to engage in risky sexual activity within the confines of the prison (AOR = 0.36, 95% CI = 0.20 &#45 0.63, p = 0.01). Qualitative interviews revealed the denial of occurrence of sexual activity in prison despite sexual desire felt by inmates;loneliness, poverty, and curiosity as motives for sexual relations;denial of occurrence of sexual violence in prison;and drug use and use of unsterilized sharps as risky sexual behaviors. Conclusion: Despite the disciplinary action meted out on inmates, prisoners still engaged in a range of risky sexual behaviors. Conjugal visitations for married inmates could be considered to reduce sexually deviant and risky alternatives of relieving sexual desire among prisoners. 展开更多

This mixed-methods study investigated how AI-enhanced English as a Foreign Language(EFL)learning environments influence students’psychological well-being through the mediating roles of motivation and language learning anxiety and the moderating role of trust.Participants were Chinese university students(N=310,62%female,mean age=18.9,SD=0.8),of whom 15 completed interviews to both add to and to clarify the evidence from the surveys.Structural equation modeling results revealed that AI use had significant indirect effects on well-being through increased motivation and reduced language learning anxiety.Trust in AI significantly moderated both paths,amplifying the motivational benefits and anxiety reduction associated with AI use.Thematic analysis supported these results,identifying three experiential themes:(1)motivational empowerment through personalization,(2)anxiety regulation through safe practice and feedback,and(3)trust as the emotional bridge between AI and well-being.The study extends AI psychology applications by empirically linking technology engagement with affective outcomes and underscores the need for human-centered and trust-enhancing design in AI-supported education.From these findings,we conclude that adaptive,transparent,and autonomy-supportive AI systems promote self-determined motivation,emotional safety,and overall psychological health among EFL learners. 展开更多

Entrepreneurial competence,as a key factor influencing the success or failure of university students in entrepreneurship,has increasingly become a major focus for higher education institutions in the context of internationalization.Taking Guilin University of Technology in China and Mongolian National University as examples,this study employs a mixed-methods approach,conducting surveys and in-depth interviews with 612 students and 32 faculty members and students from both universities to compare differences and similarities in entrepreneurial competence across four dimensions:entrepreneurial knowledge,skills,attitudes,and personality between Chinese and Mongolian students.The findings indicate that students at Guilin University of Technology possess relatively comprehensive and systematic entrepreneurial knowledge and skills,along with strong team spirit,while students at Mongolian National University demonstrate heightened risk awareness and greater sensitivity to opportunity recognition.These differences are primarily attributed to cultural traditions,educational systems,and economic environments.This research enhances our understanding of the factors shaping entrepreneurial competence among university students in different countries and offers insights for improving cross-cultural entrepreneurial education. 展开更多

We consider a nonlinear parabolic system describing compressible miscible displacement in a porous medium[4]. Continuous time and discrete time Galerkin methods are introduced to approximate the solution, and optimal H1-error estimates are obtained. This paper improves upon previously derived estimates in two aspects. Firstly, error estimates are given with no restrictions on the diffusion tensor. That is, we have included the effects of molecular diffusion and dispersion. Secondly, the complete compressible case is considered in the error analysis. 展开更多

Background Measles outbreaks re-emerged in 2013–2014 in Guangxi Zhuang Autonomous Region of China,where measles immunisation coverage is high.The discrepancy between the vaccination coverage and outbreaks indicates that timeliness is crucial,yet there is limited knowledge on the health system barriers to timely vaccination.Using integrated evidence at the household,village clinic,and township hospital levels,this study aimed to identify the determinants of failure in receiving timely measles vaccinations among children in rural Guangxi.Methods A multi-stage stratified cluster sampling survey with a nested qualitative study was conducted among children aged 18–54 months in Longan,Zhaoping,Wuxuan,and Longlin counties of Guangxi from June to August 2015.The status of timely vaccinations for the first dose of measles-containing vaccine(MCV1)and the second dose of measles-containing vaccine(MCV2)was verified via vaccination certificates.Data on household-level factors were collected using structured questionnaires,whereas data on village and township-level factors were obtained through in-depth interviews and focus group discussions.Determinants of untimely measles vaccinations were identified using multilevel logistic regression models.Results A total of 1216 target children at the household level,120 villages,and 20 township hospitals were sampled.Children were more likely to have untimely vaccination when their primary guardian had poor vaccination knowledge[MCV1,odds ratio(OR)=1.72;MCV2,OR=1.51],had weak confidence in vaccines(MCV1,OR=1.28–4.58;MCV2,OR=1.42–3.12),had few practices towards vaccination(MCV1,OR=12.5;MCV2,OR=3.70),or had low satisfaction with vaccination service(MCV1,OR=2.04;MCV2,OR=2.08).This trend was also observed in children whose village doctor was not involved in routine vaccination service(MCV1,OR=1.85;MCV2,OR=2.11)or whose township hospital did not provide vaccination notices(MCV1,OR=1.64;MCV2,OR=2.05),vaccination appointment services(MCV1,OR=2.96;MCV2,OR=2.74),sufficient and uniformly distributed sessions for routine vaccination(MCV1,OR=1.28;MCV2,OR=1.17;MCV1,OR=2.08),or vaccination service on local market days(MCV1,OR=2.48).Conclusions Guardians with poor knowledge,weak beliefs,and little practice towards vaccination;non-involvement of village doctors in routine vaccinations;and inconvenient vaccination services in township hospitals may affect timely measles vaccinations among children in rural China. 展开更多

In this paper we consider mixed finite element methods for second order elliptic problems. In the case of the lowest order Brezzi-Douglas-Marini elements （if d = 2） or Brezzi- Douglas-Duran-Fortin elements （if d = 3） on rectangular parallelepipeds, we show that the mixed method system, by incorporating certain quadrature rules, can be written as a simple, cell-centered finite difference method. This leads to the solution of a sparse, positive semidefinite linear system for the scalar unknown. For a diagonal tensor coefficient, the sparsity pattern for the scalar unknown is a five point stencil if d = 2, and seven if d = 3. For a general tensor coefficient, it is a nine point stencil, and nineteen, respectively. Applications of the mixed method implementation as finite differences to nonisothermal multiphase, multicomponent flow in porous media are presented. 展开更多

The vapor deposition chemical reaction processes, which are of extremely extensive applications, can be classified as a mathematical model by the following governing nonlinear partial differential equations containing velocity vector, temperature field, pressure field, and gas mass field. The mixed finite element （MFE） method is employed to study the system of equations for the vapor deposition chemical reaction processes. The semidiscrete and fully discrete MFE formulations are derived. And the existence and convergence （error estimate） of the semidiscrete and fully discrete MFE solutions are demonstrated. By employing MFE method to treat the system of equations for the vapor deposition chemical reaction processes, the numerical solutions of the velocity vector, the temperature field, the pressure field, and the gas mass field can be found out simultaneously. Thus, these researches are not only of important theoretical means, but also of extremely extensive applied vistas. 展开更多

The transient behavior of a semiconductor device consists of a Poisson equation for the electric potential and of two nonlinear parabolic equations for the electron density and hole density. The electric potential equation is discretized by a mixed finite element method. The electron and hole density equations are treated by implicit-explicit multistep finite element methods. The schemes are very efficient. The optimal order error estimates both in time and space are derived. 展开更多
