Background There is a critical need for effective health education methods for adolescent smoking prevention. The coproduction of antismoking videos shows promising results for adolescent health education. Objective This study explored the feasibility of a smoking prevention program using the coproduction of antismoking videos in order to empower adolescents in smoking prevention and tobacco control. A smoking prevention program based on coproduction of antismoking videos over eight sessions was implemented in a low-income neighborhood. Methods A mixed methods design with a concurrent embedded approach was used. In total, 23 adolescents participated in the program. During the prevention program, small groups of participants used video cameras and laptops to produce video clips containing antismoking messages. Quantitative data were analyzed using the Wilcoxon signed-rank test to examine changes in participants’ psychological empowerment levels between pre- and postintervention; qualitative interview data were analyzed using content analysis. Results Pre- and postcomparison data revealed that participants’ psychological empowerment levels were significantly enhanced for all three domains—intrapersonal, interactional, and behavioral—of psychological empowerment (P<.05). Interviews confirmed that the coproduction of antismoking videos is feasible in empowering participants, by supporting nonsmoking behaviors and providing them with an opportunity to help build a smoke-free community. Conclusions Both quantitative and qualitative data supported the feasibility of the coproduction of antismoking videos in empowering adolescents in smoking prevention. Coproduction of antismoking videos with adolescents was a beneficial health education method.

BackgroundThe Munich Breathlessness Service has adapted novel support services to the German context, to reduce burden in patients and carers from breathlessness in advanced disease. It has been evaluated in a pragmatic fast-track randomised controlled trial (BreathEase; NCT02622412) with embedded qualitative interviews and postal survey. The aim of this article is to describe the intervention model and study design, analyse recruitment to the trial and compare sample characteristics with other studies in the field.MethodsAnalysis of recruitment pathways and enrolment, sociodemographic and clinical characteristics of participants and carers.ResultsOut of 439 people screened, 253 (58%) were offered enrolment and 183 (42%) participated. n=97 (70%) carers participated. 186 (42%) people did not qualify for inclusion, mostly because breathlessness could not be attributed to an underlying disease. All participants were self-referring; 60% through media sources. Eligibility and willingness to participate were associated to social networks and illness-related activities as recruitment routes. Mean age of participants was 71 years (51% women), with COPD (63%), chronic heart failure (8%), interstitial lung disease (9%), pulmonary hypertension (6%) and cancer (7%) as underlying conditions. Postal survey response rate was 89%. Qualitative interviews were conducted with 16 patients and nine carers.ConclusionThe BreathEase study has a larger and more heterogeneous sample compared to other trials. The self-referral-based and prolonged recruitment drawing on media sources approximates real-world conditions of early palliative care. Integrating qualitative and quantitative components will allow a better understanding and interpretation of the results of the main effectiveness study.

Abstract Background There is increasing interest in the use of ketogenic diets (KD) as adjuvant therapy for glioblastoma (GBM). Trial aims: i) investigate protocol feasibility; ii) assess patient/carer acceptability; iii) explore the decision-making of patients’ invited to participate in KEATING; and iv) inform phase III trial design. Methods Prospective, feasibility study, with embedded qualitative design randomised 12 newly-diagnosed GBM patients to three months of medium chain triglyceride ketogenic diet (MCTKD) or the modified ketogenic diet (MKD) during chemoradiotherapy. Primary outcome was retention; secondary outcomes included recruitment rate, dietary acceptability, progression free survival (PFS) and overall survival (OS). Semi-structured interviews were conducted with a representative sample of patients and relatives (n=15). Results Recruitment targets were achieved, but recruitment rate was low (28.6%). Retention was poor; only 4 of 12 completed the three-month diet (MCTKD n=3; MKD n=1). Median duration until discontinuing was 5.2 weeks (0–7 weeks; n=8). Participants made instantaneous decisions without deliberation: relatives supported diet implementation. Decliners made considered decisions factoring diet burden and quality of life. A three-month diet was undesirable to these patients. Median PFS was 11.4 weeks and OS was 67.3 weeks. Conclusion Recruitment to a ketogenic-glioblastoma trial is possible. To assess effectiveness in a phase III clinical trial, a six week intervention period is proposed. Future trials should optimise and adequately support the decision-making of patients. The role of relatives should not be underestimated.

Full textAbstract:
The use of English among Indonesian millennials has been more widespread especially because of exposure to English has been so massive to secondary school in urban areas. There has been a concern that the increasing use of English might diminish their Indonesian language use and cultural identity. This study aims to investigate the roles of English on satellite TV programs and social media posts for Indonesian millennials, their language preference, and the consequences of language preference on their national identity. A concurrent embedded mixed methods design collecting quantitative and qualitative data was carried out through short essays and closed-questionnaires. Both questions of essay writing and closed-questionnaires were sent to students of private high schools in two big cities (Jakarta and Surabaya), aged 18 to 20 years old online. The questionnaire items were in multiple-choice and the short paragraph essay explained the importance of TV programs and social media posts for learning English. After being scrutinized, 989 respondents’ essay responses were analysed. The findings showed that TV programs and social media posts were claimed to have important roles of English learning resources. Although they practiced English through social media, they felt that they still kept themselves as Indonesians when using English on social media

The purpose of this study is to analyze the effect of flash interactive media in improving students' understanding of concepts in elementary schools. This type of research was mixed methods with an embedded experimental model design. Quantitative data analysis techniques on the variable understanding of the concept, namely the results of the analysis of the students' pretest and posttest questions by using paired sample t-test. The results of the analysis are then triangulated with the qualitative Focus Group Discussion (FGD) data and the results of the interviews. This study involved 54 students who were selected by using the nonprobability sampling technique: purposive sampling. The population consists of 31 public schools and 13 private schools. The results of this study show a significant increase in the concept of understanding in the form of an increase in the average score understanding of concepts by 17.82%. According to questionnaire data that has been distributed, teachers and students respond very well to learning using the flash interactive media. Students' motivation to learn accompanies an increase in their understanding of concepts. It appears that the application of flash interactive media in science learning has a positive impact on increasing motivation that has an impact on increasing students' conceptual understanding.

Objectives: To gain insight into children’s health-related knowledge and understanding of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) and COVID-19, and measures adopted to mitigate transmission. Design: A child-centred qualitative creative element embedded in an online mixed-methods survey of children aged 7–12 years. Setting: Children participated in the study in six countries – the UK, Australia, Sweden, Brazil, Spain and Canada. Method: A qualitative creative component, embedded in an online survey, prompted children to draw and label a picture. Children were recruited via their parents using the researchers’ professional social media accounts, through known contacts, media and websites from health organisations within each country. Analysis of the form and content of the children’s pictures took place. Results: A total of 128 children (mean age 9.2 years) submitted either a hand-drawn ( n = 111) or digitally created ( n = 17) picture. Four main themes were identified which related to children’s health-related knowledge of (1) COVID-19 and how it is transmitted; (2) measures and actions to mitigate transmission; (3) places of safety during the pandemic; and (4) children’s role in mitigating COVID-19 transmission. Conclusion: Children’s pictures indicated a good understanding of the virus, how it spreads and how to mitigate transmission. Children depicted their actions during the pandemic as protecting themselves, their families and wider society.

Full textAbstract:
PurposeLittle is known about the variations in service co-creation on social media, despite the resource integrating capabilities and co-creator roles afforded by these platforms. The gap is even more troubling in the nonprofit sector, where leveraging public interaction on social media is prevalent and vital to charitable and philanthropic endeavors. Arguably, such interaction is embedded in resource integrating activities leading to nonprofit service co-creation. This paper reports the forms, dimensions or service co-creation measures enabled by social media use in the nonprofits' sector.Design/methodology/approachThe authors conducted a sequential exploratory mixed methods design. First, the authors interviewed 19 social media managers in education, health and social service nonprofit organizations to identify the varieties in service co-creation realized. Second, the authors surveyed 73 nonprofit organizations on social media and gathered 267 useable responses, which were used to analyze and validate the identified forms of service co-creation.FindingsThe authors found that nonprofit organizations realize up to seven forms of service co-creation using social media. These include co-ideating to tweak service ideas, co-diagnosing social needs and problems, co-assessing service events, co-transforming services to targeted communities, co-advocating for community and service reach, co-resourcing in service delivery, and co-experiencing through a pool of diverse service experiences.Originality/valueThis study develops a reliable and valid multidimensional measure for nonprofit service co-creation enabled by social media platforms. Theoretically, this study offers a nonprofit service co-creation model to drive nuanced explanatory research and service co-creation perspectives in other contexts and engagement platforms. Managerially, this research illustrates the variations in service co-creation, which inform the strategic value of social media to nonprofits and will assist nonprofit practitioners in planning and evaluating their service co-creation outcomes.

Full textAbstract:
The emergence of social media has allowed people to express their feelings on products, services, films, and so on. The feeling is the user’s view or attitude towards any topic, object, event, or service. Overall, feelings have always influenced people’s decision-making. In recent years, emotions have been analyzed intensively in natural language, but many problems still have to be watched. One of the most important problems is the lack of precise classification resources. Most of the research into feeling gradation is concerned with the issue of polarity grading, although, in many practical applications, this relatively grounded feeling measure is insufficient. Design methods are therefore essential, which can accurately classify feelings into a natural language. The principal goal of the research is to develop an overflow of grammatical rules-based classification of Indian language tweets. In this work, three main challenges are identified to classify feelings in Indian language tweets and possible methods for tackling such issues. Firstly, it has been found that the informal nature of tweets is crucial for the classification of feelings. Based on the tweets, the mental illness of the person has been classified. Therefore, to categorize Indian language tweets, a combination of grammar rules based on adjectives and negations is proposed. Secondly, people often express their feelings with slang words, abbreviations, and mixed words. A technique called field tags is used to include nongrammatical arguments such as slang words and diverse words. Thirdly, if a tweet is more complex, the morphological richness of the Indian language results in a loss of performance. The grammar rules are embedded in N-gram techniques and machine learning methods. These methods are grouped into three approaches, which functionally predict Indian language tweets with syntactic words.

Introduction: Three-fourths of maternal deaths occur from direct obstetric complications. These life-threatening pregnancy-related outcomes are avoidable through ensuring that mothers have access to adequate and proper maternal health services and prompt management of any complications during pregnancy or childbirth process. This study examined the relationship between social network structures and birth attendant decisions among women in Nakuru County, Kenya. Methods: The study applied a mixed-method approach that employs a convergent parallel design. Interviewer administered questionnaires and semi-structured interviews were used to collect quantitative and qualitative data among women of birth giving age and community health workers (CHWs) respectively. Chi-square tests for independence were used to assess whether the dependent variable and categorical independent variables are independent at p< 0.05 significance levels. Binomial logistic regression technique was employed to identify variables that are likely to be essential predictors for the dependent variable. Qualitative data from in-depth interviews with key informants was analyzed through content analysis using NVivo 10. Results: About 55% of the women were embedded in homogeneous networks, 76% had high Skilled Birth Attendants (SBA) endorsement networks, and the average number of social networks was 2.4 (SD=1.1, median = 2). There was no significant relationship between social network size and birth attendant decision (χ2(2), p=.072). There was, however, a significant relationship between social network content and birth attendant decision (χ2(1)=55.604, p< 0.001). Social network homogeneity was also strongly related to birth attendant choice (χ2(1)=21.152, p<0.001). Women embedded in social networks with high SBA endorsement had 5.28 higher odds of giving birth in a health facility than their counterparts embedded in low SBA endorsement. Those embedded in a homogeneous network had a 70% reduction in odds of facility delivery. Conclusion: According to the study findings, social networks can either facilitate or constrain facility utilization during birth, and thus health education and mother mobilization interventions promoting facility birth should leverage on the role of social networks. Key words: social networks, mixed methods, birth attendant decisions, skilled birth attendants

Full textAbstract:
Background Midwifery-led units (MUs) are recommended for ‘low-risk’ births by the National Institute for Health and Care Excellence but according to the National Audit Office were not available in one-quarter of trusts in England in 2013 and, when available, were used by only a minority of the low-risk women for whom they should be suitable. This study explores why. Objectives To map the provision of MUs in England and explore barriers to and facilitators of their development and use; and to ascertain stakeholder views of interventions to address these barriers and facilitators. Design Mixed methods – first, MU access and utilisation across England was mapped; second, local media coverage of the closure of free-standing midwifery units (FMUs) were analysed; third, case studies were undertaken in six sites to explore the barriers and facilitators that have an impact on the development of MUs; and, fourth, by convening a stakeholder workshop, interventions to address the barriers and facilitators were discussed. Setting English NHS maternity services. Participants All trusts with maternity services. Interventions Establishing MUs. Main outcome measures Numbers and types of MUs and utilisation of MUs. Results Births in MUs across England have nearly tripled since 2011, to 15% of all births. However, this increase has occurred almost exclusively in alongside units, numbers of which have doubled. Births in FMUs have stayed the same and these units are more susceptible to closure. One-quarter of trusts in England have no MUs; in those that do, nearly all MUs are underutilised. The study findings indicate that most trust managers, senior midwifery managers and obstetricians do not regard their MU provision as being as important as their obstetric-led unit provision and therefore it does not get embedded as an equal and parallel component in the trust’s overall maternity package of care. The analysis illuminates how provision and utilisation are influenced by a complex range of factors, including the medicalisation of childbirth, financial constraints and institutional norms protecting the status quo. Limitations When undertaking the case studies, we were unable to achieve representativeness across social class in the women’s focus groups and struggled to recruit finance directors for individual interviews. This may affect the transferability of our findings. Conclusions Although there has been an increase in the numbers and utilisation of MUs since 2011, significant obstacles remain to MUs reaching their full potential, especially FMUs. This includes the capacity and willingness of providers to address women’s information needs. If these remain unaddressed at commissioner and provider level, childbearing women’s access to MUs will continue to be restricted. Future work Work is needed on optimum approaches to improve decision-makers’ understanding and use of clinical and economic evidence in service design. Increasing women’s access to information about MUs requires further studies of professionals’ understanding and communication of evidence. The role of FMUs in the context of rural populations needs further evaluation to take into account user and community impact.

AbstractObjectiveAccording to the Family Ecological Model (FEM), parenting behaviours are shaped by the contexts in which families are embedded. In the present study, we utilize the FEM to guide a mixed-methods community assessment and summarize the results. Additionally, we discuss the utility of the FEM and outline possible improvements.DesignUsing a cross-sectional design, qualitative and quantitative methods were used to examine the ecologies of parents' cognitions and behaviours specific to children's diet, physical activity and screen-based behaviours. Results were mapped onto constructs outlined in the FEM.SettingThe study took place in five Head Start centres in a small north-eastern city. The community assessment was part of a larger study to develop and evaluate a family-centred obesity prevention programme for low-income families.SubjectsParticipants included eighty-nine low-income parents/caregivers of children enrolled in Head Start.ResultsParents reported a broad range of factors affecting their parenting cognitions and behaviours. Intrafamilial factors included educational and cultural backgrounds, family size and a lack of social support from partners. Organizational factors included staff stability at key organizations, a lack of service integration and differing school routines. Community factors included social connectedness to neighbours/friends, shared norms around parenting and the availability of safe public housing and play spaces. Policy- and media-related factors included requirements of public assistance programmes, back-to-work policies and children's exposure to food advertisements.ConclusionsBased on these findings, the FEM was refined to create an evidence-based, temporally structured logic model to support and guide family-centred research in childhood obesity prevention.

AbstractIntroduction:The Clinical and Translational Science Award (CTSA) Program is a Consortium of nearly 60 academic medical research centers across the USA and a natural network for evaluating the spread and uptake of translational research innovation across the Consortium.Methods:Dissemination of the Accrual to Clinical Trials (ACT) Network, a federated clinical informatics data network for population-based cohort discovery, began January 2018 across the Consortium. Diffusion of innovation theory guided dissemination design and evaluation. Mixed-methods assessed the spread and uptake across the Consortium through July 1, 2019 (n = 48 CTSAs). Methods included prospective time activity tracking (Kaplan–Meier curves), and survey and qualitative interviews.Results:Within 18 months, nearly 80% of CTSAs had joined the data network and two-thirds of CTSAs achieving technical readiness had initiated launch to local clinical investigators. Over 10,000 ACT Network queries are projected for 2019; and by 2020, nearly all CTSAs will have joined the network. Median time-from-technical-readiness-to-local-launch was 154 days (interquartile range: 87–225 days]. Quality improvement processes reduced time-to-launch by 35.2% (64 days, p = 0.0036). Lessons learned include: (1) conceptualize dissemination as two-stage adoption demonstrating value for both CTSA hub service providers and clinical investigators; (2) include institutional trial into dissemination strategies so CTSA hubs can refine internal workflows and gather local user feedback endorsement; (3) embrace designing-for-dissemination during technology development; and (4) sustain adaptive dissemination and customer relationship management to keep CTSA hubs and users engaged.Conclusions:Scale-up and spread of the ACT Network provides lessons learned for others disseminating innovation across the CTSA Consortium. The Network is primed for embedded implementation research.

Full textAbstract:
The consequences of leprosy go beyond the physical, social and psychological, as leprosy can drive persons affected and their families into poverty, stigmatization and disability. This paper describes the impact of a socio-economic development (SED) intervention that uses a twin-track approach (two micro-credit models) to reduce leprosy-related stigma in Cirebon District, Indonesia. A randomized-controlled mixed-methods study design was used to test the effectiveness of the SED intervention. Three scales were used to measure stigma and participation restrictions among 30 SED clients and 57 controls, 20 in-depth interviews with SED clients and seven Focus Group Discussions (FGDs) with key persons were held and 65 profiles of the clients were written up and analysed. The qualitative data shows the socio-economic status of 44 out of 65 SED clients (67%) improved. The median family income increased by 25%, more clients reported higher self-esteem, better interaction with neighbours and less stigma than before, although disclosure concerns remained an issue. The scales indicate a positive effect of the intervention on reducing stigma (e.g., Stigma Assessment and Reduction of Impact (SARI) stigma scale mean difference total score of pre and post assessment for SED clients versus the control group was 8.5 versus 5.6). A twin track socio-economic intervention, if embedded and integrated, can increase participation, and be constructive in reducing leprosy-related stigma.

Abstract This paper introduces the rapidly growing modern mixed methods research (MMR) and its application in a Chinese cancer screening program. While some previous researchers have incorporated quantitative and qualitative data in research, recent mixed methods developments have provided significant clarity that can guide those new to the MMR field. Understanding the context for using MMR and examining a complex mixed methods evaluation study in Taiwan can help illustrate opportunities for and application of mixed methods in Asians. The Taiwan Cervical Cancer Screening Education Program is used as an exemplar of a multi-phase complex mixed methods evaluation study showcasing various MMR designs. These include an exploratory sequential design to develop culturally sensitive study instrument, iterative concurrent and sequential mixed methods for intervention mapping, and an embedded mixed methods evaluation design to assess impact. Visual diagrams are introduced to facilitate communication of mixed methods design procedures and products in each phase.

36 Background: The association of TMPRSS2-ERG fusions and ERG expression in prostate cancer (PC) with adverse clinical outcomes has been controversial, with mixed results in the literature. We conducted a study to test whether tumor-derived gene expression profiles, including the presence of TMPRSS2-ERG fusions and ERG gene expression, are associated with clinical recurrence (cR) after radical prostatectomy (RP). Methods: All patients with clinical stage T1/T2 prostate cancer treated with RP at CC from 1987 to 2004 were identified (n∼f2,600). A cohort sampling design was used to select 127 patients with cR and 374 patients without cR after RP. For each patient a primary Gleason pattern (GP) sample, secondary (or highest) GP sample, and an adjacent nontumor tissue sample were evaluated. Surgical Gleason Score (GS) and clinical data were centrally reviewed. RNA was extracted from 6 manually dissected 10 μ m formalin-fixed paraffin-embedded sections obtained from RP specimens and expression of TMPRSS2-ERGa, TMPRSS2-ERGb, ERG and reference genes were quantified using RT-PCR. Times to cR, PSA recurrence, and PC death were analyzed using Cox PH regression. Results: Blocks from 441 patients were evaluable. Median F/U was 5.8 years. Patients were mostly Caucasian (83%), clinical stage T1 (66%), had baseline PSA <10 ng/mL (82%), and had surgical Gleason score ≤7 (87%). 848 tumor samples and 410 non-tumor samples were assessed. TMPRSS2-ERGa and/or TMPRSS2-ERGb fusions were present in 51.8% of tumor samples and 7.5% of non-tumor samples. There was 89% concordance (95% CI: 86%, 92%) for TMPRSS2-ERG fusion status between the 2 tumor samples for each patient. High ERG expression was strongly associated with the presence of TMPRSS2-ERG fusions (p <0.01). We did not find an association between TMPRSS2-ERG a/b gene rearrangement or ERG expression with cR, PSA recurrence, PC death, or surgical GS (p > 0.2). Conclusions: This study was notable for the large number of cR events, use of a standardized quantitative assay, and rigorous central review of pathology and clinical data. We did not find an association of TMPRSS2-ERG gene rearrangements or ERG expression with aggressiveness of prostate cancer post RP. [Table: see text]

Natural language processing techniques have increased the volume and variety of text data that can be analyzed. The aim of this study was to identify the positive and negative topical sentiments among diet, diabetes, exercise, and obesity tweets. Using a sequential explanatory mixed-method design for our analytical framework, we analyzed a data corpus of 1.7 million diet, diabetes, exercise, and obesity (DDEO)-related tweets collected over 12 months. Sentiment analysis and topic modeling were used to analyze the data. The results show that overall, 29% of the tweets were positive, and 17% were negative. Using sentiment analysis and latent Dirichlet allocation (LDA) topic modeling, we analyzed 800 positive and negative DDEO topics. From the 800 LDA topics—after the qualitative and computational removal of incoherent topics—473 topics were characterized as coherent. Obesity was the only query health topic with a higher percentage of negative tweets. The use of social media by public health practitioners should focus not only on the dissemination of health information based on the topics discovered but also consider what they can do for the health consumer as a result of the interaction in digital spaces such as social media. Future studies will benefit from using multiclass sentiment analysis methods associated with other novel topic modeling approaches.

Background The limitations of ‘knowledge transfer’ are increasingly recognised, with growing interest in ‘knowledge co-production in context’. One way of achieving the latter is by ‘embedding’ researchers in health service settings, yet how to deliver such schemes successfully is poorly understood. Objectives The objectives were to examine the nature of ‘embedded knowledge co-production’ and explore how embedded research initiatives can be designed more effectively. Design The study used four linked workstreams. Workstream 1 involved two parallel literature reviews to examine how ‘knowledge co-production’ and ‘embedded research’ are conceptualised, operationalised and discussed. In workstream 2, a scoping review of exisiting or recent ‘embedded researcher’ schemes in UK health settings was carried out. Workstream 3 involved developing four in-depth case studies on such schemes to understand their mechanisms, effectiveness and challenges. In workstream 4, insights from the other workstreams were used to provide recommendations, guidance and templates for the different ways embedded co-production may be framed and specified. The overall goal was to help those interested in developing and using such approaches to understand and address the design choices they face. Setting Embedded research initiatives in UK health settings. Data sources Data were sourced from the following: analysis of the published and grey literature (87 source articles on knowledge co-production, and 47 published reports on extant embedded research initiatives), documentation and interviews with key actors across 45 established embedded research initiatives, in-depth interviews and site observations with 31 participants over 12 months in four intensive case studies, and informal and creative engagement in workshops (n = 2) and with participants in embedded research initiatives who joined various managed discussion forums. Participants The participants were stakeholders and participants in embedded research initiatives. Results The literature reviews from workstream 1 produced practical frameworks for understanding knowledge co-production and embedded research initiatives, which, with the scoping review (workstream 2), informed the identification and articulation of 10 design concerns under three overarching categories: intent (covering outcomes and power dynamics), structures (scale, involvement, proximity and belonging) and processes (the functional activities, skills and expertise required, nature of the relational roles, and the learning mechanisms employed). Current instances of embedded research were diverse across many of these domains. The four case studies (workstream 3) added insights into scheme dynamics and life cycles, deepening understanding of the overarching categories and showing the contingencies experienced in co-producing knowledge. A key finding is that there was often a greater emphasis on embeddedness per se than on co-production, which can be hard to discern. Finally, the engaging and influencing activities running throughout (workstream 4) allowed these research-rooted insights to be translated into practical tools and resources, evidenced by peer-reviewed publications, for those interested in exploring and developing the approach. Conclusions Embedded research has a strong underpinning rationale, and more is becoming known about its design and management challenges. The tools and resources developed in this project provide a coherent evidence-informed framework for designing, operationalising and managing such schemes. It cannot yet be said with clarity that the potential benefits of embedded research are always deliverable, nor what the cost would be. Future work With the means to describe and categorise different types of embedded research initiatives, more evaluative work is now needed to examine the relative merits and costs of different designs.

Background Online health communities (OHCs) have emerged as the leading venues for behavior change and health-related information seeking. The soul and success of these digital platforms lie in their ability to foster social togetherness and a sense of community by providing personalized support. However, we have a minimal understanding of how conversational posts in these settings lead to collaborative societies and ultimately result in positive health changes through social influence. Objective Our objective is to develop a content-specific and intent-sensitive methodological framework for analyzing peer interactions in OHCs. Methods We developed and applied a mixed-methods approach to understand the manifestation of expressions in peer interactions in OHCs. We applied our approach to describe online social dialogue in the context of two online communities, QuitNet (QN) and the American Diabetes Association (ADA) support community. A total of 3011 randomly selected peer interactions (n=2005 from QN, n=1006 from ADA) were analyzed. Specifically, we conducted thematic analysis to characterize communication content and linguistic expressions (speech acts) embedded within the two data sets. We also developed an empirical user persona based on their engagement levels and behavior profiles. Further, we examined the association between speech acts and communication themes across observed tiers of user engagement and self-reported behavior profiles using the chi-square test or the Fisher test. Results Although social support, the most prevalent communication theme in both communities, was expressed in several subtle manners, the prevalence of emotions was higher in the tobacco cessation community and assertions were higher in the diabetes self-management (DSM) community. Specific communication theme-speech act relationships were revealed, such as the social support theme was significantly associated (P<.05) with 9 speech acts from a total of 10 speech acts (ie, assertion, commissive, declarative, desire, directive, expressive, question, stance, and statement) within the QN community. Only four speech acts (ie, commissive, emotion, expressive, and stance) were significantly associated (P<.05) with the social support theme in the ADA community. The speech acts were also significantly associated with the users’ abstinence status within the QN community and with the users’ lifestyle status within the ADA community (P<.05). Conclusions Such an overlay of communication intent implicit in online peer interactions alongside content-specific theory-linked characterizations of social media discourse can inform the development of effective digital health technologies in the field of health promotion and behavior change. Our analysis revealed a rich gradient of expressions across a standardized thematic vocabulary, with a distinct variation in emotional and informational needs, depending on the behavioral and disease management profiles within and across the communities. This signifies the need and opportunities for coupling pragmatic messaging in digital therapeutics and care management pathways for personalized support.

This study aimed to perform a case study of the artworks colored using mixed media by applying qualitative methods. The teacher and the students wrote the story and completed the storyboard through interactive discussion teaching. With the knowledge of the properties of current painting papers and media used for coloring, the teacher was able to guide the students to choose paper of better quality, and select proper mixed media to create their artworks, so that the picture book could be richer and more delicate. Furthermore, documentary analysis was performed with current documents related to picture books to provide the students references for their artworks. Finally, the students were guided to process their graphs and arrange the layout using computer software, to complete a picture book artwork colored using mixed media by both hand-drawing and computer graphing and this study.

Background. Mixed methods research uses qualitative and quantitative methods together in a single study or a series of related studies.Objectives. To review the prevalence and quality of mixed methods studies in complementary medicine.Methods. All studies published in the top 10 integrative and complementary medicine journals in 2012 were screened. The quality of mixed methods studies was appraised using a published tool designed for mixed methods studies.Results. 4% of papers (95 out of 2349) reported mixed methods studies, 80 of which met criteria for applying the quality appraisal tool. The most popular formal mixed methods design was triangulation (used by 74% of studies), followed by embedded (14%), sequential explanatory (8%), and finally sequential exploratory (5%). Quantitative components were generally of higher quality than qualitative components; when quantitative components involved RCTs they were of particularly high quality. Common methodological limitations were identified. Most strikingly, none of the 80 mixed methods studies addressed the philosophical tensions inherent in mixing qualitative and quantitative methods.Conclusions and Implications. The quality of mixed methods research in CAM can be enhanced by addressing philosophical tensions and improving reporting of (a) analytic methods and reflexivity (in qualitative components) and (b) sampling and recruitment-related procedures (in all components).

Purpose This paper aims to present a new method, named as augmented polynomial dimensional decomposition (PDD) method, for robust design optimization (RDO) and reliability-based design optimization (RBDO) subject to mixed design variables comprising both distributional and structural design variables. Design/methodology/approach The method involves a new augmented PDD of a high-dimensional stochastic response for statistical moments and reliability analyses; an integration of the augmented PDD, score functions, and finite-difference approximation for calculating the sensitivities of the first two moments and the failure probability with respect to distributional and structural design variables; and standard gradient-based optimization algorithms. Findings New closed-form formulae are presented for the design sensitivities of moments that are simultaneously determined along with the moments. A finite-difference approximation integrated with the embedded Monte Carlo simulation of the augmented PDD is put forward for design sensitivities of the failure probability. Originality/value In conjunction with the multi-point, single-step design process, the new method provides an efficient means to solve a general stochastic design problem entailing mixed design variables with a large design space. Numerical results, including a three-hole bracket design, indicate that the proposed methods provide accurate and computationally efficient sensitivity estimates and optimal solutions for RDO and RBDO problems.

Chinese tobacco packaging can be viewed as complex advertising practice. On the one hand, the cigarette pack is used to attract consumers, and on the other hand, it plays a role in health communication for discouraging smoking in China. When these two functions are mixed together, the media effect of the cigarette pack is supposed to be ambiguous and blurred. However, media effects of tobacco packaging in China seem to be lopsided: it is very effective in attracting consumers, but largely ineffective in discouraging smoking. What causes this phenomenon? Since the cigarette pack functions as a medium in the Chinese market, it has the power to asymmetrically influence the actions of others, but its power is subservient to the will of those who empower it. By using literature-based and focus groups methods, that the is piece of research finds that the incomplete health communication effect of cigarette packs is due to various reasons, such as political, economic, and cultural ones. The most influential factor is political, as the tobacco industry in China is entirely at the mercy of the government. The media effects and effectiveness of the package depend mainly on the government’s will, interests, and values.

Mixed methods research is becoming an important methodology for the investigation of various topics in applied linguistics. However, data integration remains a challenge for mixed methods researchers and thus needs further development. This study discusses the integrative data analysis strategies used in an embedded mixed methods study in applied linguistics, illustrated through two phases of the study, and the way in which the adoption of a pragmatic approach explicitly aids data integration by abductive reflection on the knowledge acquired. This study investigated the language learning strategies used by English as a Foreign Language nursing students in higher education in Macao, and the effectiveness of the students’ learning outcomes as a result of strategy instruction. Six integrative data analysis strategies are discussed, and the explicit pragmatic approach that guided the exploratory sequential design sheds further light on the integrative data analysis.

The learning topic of this study was the creative designs of picture books in the basic design curriculum. The research subjects were the students from the Department of Commercial Design of a technology university. Hand drawings were combined with computer graphics to perform the image art designs using mixed media of innovative technology, to explore the achievements of applying the innovative technology methods in aesthetics education. During the process of creating works, the teachers and the students had continuously discussed and made modifications. Finally, the students were asked to present their works through oral presentations. The scores were given by two professional design teachers. Among all the works, the picture book titled Lop was the one with the best performance. The story was that the leading characters ears were too long, causing a lot of inconvenience. He was even mocked at by his friends. Thus, he hated his own ears a lot. However, in an accident, he unexpectedly found the advantage of his lop ears and learned to accept himself. The images of this picture book were colorful while still friendly and sincere, properly presenting the scenes in the story, helping children to develop the concept of loving both others and themselves.

Background:Mass media campaigns are a necessary tool for public health practitioners to reach large populations and promote healthy behaviors. Most health scholars have concluded that mass media can significantly influence the health behaviors of populations; however the effects of such campaigns are typically modest and may require significant resources. A recent Community Preventive Services Task Force review on stand-alone mass media campaigns concluded there was insufficient evidence to determine their effectiveness in increasing physical activity, partly due to mixed methods and modest and inconsistent effects on levels of physical activity.Methods:A secondary analysis was performed on the campaigns evaluated in the Task Force review to determine use of campaign-building principles, channels, and levels of awareness and their impact on campaign outcomes. Each study was analyzed by 2 reviewers for inclusion of campaign building principles.Results:Campaigns that included 5 or more campaign principles were more likely to be successful in achieving physical activity outcomes.Conclusion:Campaign success is more likely if the campaign building principles (formative research, audience segmentation, message design, channel placement, process evaluation, and theory-based) are used as part of campaign design and planning.

IntroductionHospital group models represent an organisational form that aims to bring together multiple provider organisations with a central headquarters and unified leadership responsible for locally managed operating units, standardised systems and a value-set shared across the group. These models seek to improve outcomes by reducing unwarranted variations in care provision and reducing costs through economies of scale. There is limited evidence on the impact and processes of implementing these models, so this study aims to evaluate one case study of a hospital group model.Methods and analysisWe will conduct a formative, mixed-methods evaluation using an embedded research approach to analyse the implementation of the model and its impact on outcomes and costs. We will carry out a multisited ethnography to analyse the programme theory for model design and implementation, the barriers and facilitators in the implementation; and wider contextual issues that influence implementation using semi-structured interviews (n=80), non-participant observations (n=80 hours), ‘shadowing’ (n=20 hours) and documentary analysis. We will also carry out an economic evaluation composed of a cost-consequence analysis and a return on investment analysis to evaluate the costs of creating and running the model and balance these against the potential cost-savings.Ethics and disseminationThe study protocol was reviewed by the local R&D Office and University College London Ethics Committee and classified as a service evaluation, not requiring approval by a research ethics committee. We will follow guidelines for informed consent, confidentiality and information governance, and address issues of critical distance prevalent in embedded research. Findings will be shared at regular time points to inform the implementation of the model. The evaluation will also generate: an evaluation framework to evaluate future changes; recommendations for meaningful baseline data and measuring improvement; identification of implementation costs and potential cost-savings; and lessons for the National Health Service on implementing these models.

Objective. To analyze the relationship between the position of embedded mesiodens in maxilla and surgical approach in children and thus provide reference materials for surgical design. Methods. According to the preoperative cone-beam computed tomography (CBCT) examination, the location and surgical approach characteristics of 625 children aged 4-16 years old who presented with embedded mesiodens in maxilla and were diagnosed in our department from January 2016 to December 2021 were statistically analyzed. Results. There were 877 embedded mesiodens in 625 children. The selected cases were classified according to the axial angle relationship between mesiodens and adjacent normal teeth or tooth germs, including 84 cases of acute angle type (including the same direction) (13.4%), 66 cases of vertical type (10.6%), 114 cases of obtuse angle type (18.2%), 271 cases of inverted type (43.4%), and 90 cases of mixed type (14.4%). The palatal gingival margin approach was the most selected surgical approach for the cases of acute angle (including synclastic), obtuse angle, and inverted type, and the palatal gingival margin approach and the combined labial-palatal approach were the most selected surgical approach for the cases of vertical and mixed type. Conclusion. Palatal gingival margin approach was the most common surgical approach for various types of embedded mesiodens in maxilla in children. Surgeons should classify the case of mesiodens according to the preoperative imaging examination and design the surgical approach reasonably.

Full textAbstract:
This article looks at direct frequency domain design for satisfying robust performance objectives in uncertain, linear time invariant (LTI) plants embedded in a single feedback loop. The uncertain plants may be described by parametric, nonparametric (or unstructured), or mixed uncertain models. Quantitative Feedback Theory (QFT) is one frequency domain design methodology that is direct and is equally effective with any of these models. It can be separated from other frequency domain robust control methods such as H∞ optimal control, μ synthesis, and LQG/LTR for at least (i) its emphasis on cost of feedback measured in terms of controller bandwidth, (ii) its ability to deal nonconservatively with parametric, nonparametric and mixed uncertainty models, and (iii) its utilization of both amplitude and phase of the loop transfer function, pointwise in frequency, for the quantification of robust performance. An exposition of these attributes, unique to QFT, and the basic design methodology, coupled with a recently developed mathematical framework and some existence results for the standard single-loop QFT problem are the salient features of this paper.

The aim of this study is to gain scientific insight into internationally-accepted criteria for quality reporting of mixed methods research (MMR). Articles published post-2012 in a particular journal, which referred to “mixed methods” and “tourism”, and reported that qualitative and quantitative data were collected, were drawn from Google Scholar and Scopus. The reporting quality of these studies was analysed according to the GRAMMS framework (Good Reporting of a Mixed Methods Study). Most of the articles in the data set did not report on all the elements embedded in GRAMMS. It must not be seen as a reflection of the quality of the MMR design itself, nor is the study flawed. It indicates gaps in the reporting of important MMR elements that could be addressed in future research. Exemplars were identified that could serve as case studies for researchers in terms of the quality of reporting on MMR. Editorial boards should adopt guidelines on how MMR could be presented in articles submitted to their journals. These guidelines could assist authors in preparing their articles to conform to international standards on the reporting of MMR studies. Peer reviewers should use the guidelines to judge the quality of reporting on MMR methodology in articles under review. This study could also serve as a future reference for researchers, postgraduate students and supervisors who aim to incorporate MMR in their research.

This study examines social media use for public engagement during the Cape Town water crisis in South Africa. The study applies technology affordance and attribution theories to explore social media features (affordances) utilised by local authorities and the public, meanings embedded in the social media posts and the attributions of the water crisis cause among the actors. Data gathering and analysis followed mixed methods. Qualitative data were gathered using key informant interviews and netnography (data scrapping on Twitter) while a household survey (n= 96) was conducted to obtain quantitative data. The university research committee and City of Cape Town issued ethical clearances. During the water crisis, metavoicing, persistent engagement and visibility emerged as social media affordances. Social media posts reflected societal dynamics and attributed the crisis as external, unstable, and controllable. These findings are critical towards handling future crises and suggest collaborative efforts as the desirable action.

Full textAbstract:
Background The literature on how to communicate reform in organizations has mainly focused on levels of hierarchy and has largely ignored the variety of professions that may be found within an organization. In this study, we focus on the relationship between media type and professional responses. Objective The objective of this study was to investigate whether and how belonging to a profession influences the choice of communication media and the perception of information when a technical innovation is implemented in a health care setting. Methods This study followed a mixed methods design based on observations and participant studies, as well as a survey of professionals in psychiatric health care in Sweden. The χ2 test was used to detect differences in perceptions between professional groups. Results The use of available communication media differed among professions. These differences seem to be related to the status attached to each profession. The sense-making of the information appears to be similar among the professions, but is based on their traditional professional norms rather than on reflection on the reform at hand. Conclusions When communicating about the implementation of a new technology, the choice of media and the message need to be attuned to the employees in both hierarchical and professional terms. This also applies to situations where professional employees are only indirectly affected by the implementation. A differentiated communication strategy is preferred over a downward cascade of information.

Introduction: Rural areas are disproportionally affected by lung cancer late-stage incidence and mortality. Lung cancer screening (LCS) is recommended to find lung cancer early and reduce mortality, yet uptake is low. The purpose of this study was to elucidate the barriers to, facilitators of, and suggested interventions for increasing LCS among a rural screening-eligible population using a mixed methods concurrent embedded design study. Methods: Qualitative and quantitative data were collected from rural-residing adults who met the eligibility criteria for LCS but who were not up-to-date with LCS recommendations. Study participants (n = 23) took part in 1 of 5 focus groups and completed a survey. Focus group discussions were recorded, transcribed, and coded through a mixed deductive and inductive approach. Survey data were used to enhance and clarify focus group results; these data were integrated in the design and during analysis, in accordance with the mixed methods concurrent embedded design approach. Results: Several key barriers to LCS were identified, including an overall lack of knowledge about LCS, not receiving information or recommendation from a health care provider, and lack of transportation. Key facilitators were receiving a provider recommendation and high motivation to know the screening results. Participants suggested that LCS uptake could be increased by addressing provider understanding and recommendation of LCS and conducting community outreach to promote LCS awareness and access. Conclusion: The results suggest that the rural screening-eligible population is generally receptive to LCS. Patient-level factors important to getting this population screened include knowledge, transportation, motivation to know their screening results, and receiving information or recommendation from a provider. Addressing these factors may be important to increase rural LCS uptake.

The number of international students studying in the Republic of Korea has increased tremendously over the last 20 years, marking a change in regional student mobility trends. While most international degree students tend to originate in countries in Asia, signifying regionalization versus internationalization, exchange students are diverse by nationality/ region. This concurrent nested mixed-methods study sought to investigate the pull factors of a Korean university among exchange students. 564 students completed an electronic questionnaire and through on campus interviews. Quantitative results suggested that exchange students found characteristics about Korea attractive (e.g., K-pop) as well as wanting international and/or cross-cultural experiences, to be the most appealing. 10 students participated in interviews, and findings showed that students became interested in Korea by exposure to popular media, as well as wanting a diverse, international study environment. The implications of these findings are discussed in terms of university inbound program promotion/marketing and program design/development for short-term mobility, along with areas for future research.

Full textAbstract:
Videos are well-received methods for storytellers to communicate various narratives. To further engage viewers, we introduce a novel visual medium where data visualizations are embedded into videos to present data insights. However, creating such data-driven videos requires professional video editing skills, data visualization knowledge, and even design talents. To ease the difficulty, we propose an optimization method and develop SmartShots, which facilitates the automatic integration of in-video visualizations. For its development, we first collaborated with experts from different backgrounds, including information visualization, design, and video production. Our discussions led to a design space that summarizes crucial design considerations along three dimensions: visualization, embedded layout, and rhythm. Based on that, we formulated an optimization problem that aims to address two challenges: (1) embedding visualizations while considering both contextual relevance and aesthetic principles and (2) generating videos by assembling multi-media materials. We show how SmartShots solves this optimization problem and demonstrate its usage in three cases. Finally, we report the results of semi-structured interviews with experts and amateur users on the usability of SmartShots.

Wearable Mixed Reality (MR) technology is a tool that gives people a new enhanced experience that they have not encountered before. This study shows the process of designing new museum experiences while considering how this technology changes previous museum experiences, what those experiences are, and what people should feel through these experiences. This process was systematically conducted according to the UX design process of analysis, synthesis, and evaluation. In the analysis step, six types of museum artifact viewing experiences were defined: knowing, restoring, exploring, expanded scale, encountering, and sharing experience through research and user surveys related to the museum experience. In addition, through research analysis related to MR technology, presence, flow, and natural interaction were defined as three essential factors that users should feel in the MR experience. In the synthesis stage, optimized wearable MR experiences were designed and implemented by applying the necessary experience types and essential factors according to the characteristics of each artifact. In the evaluation stage, user experience evaluations such as user experience tests for essential factors in the MR experience, User Experience Questionnaire (UEQ) tests for interaction products, and the Visual Aesthetics of Websites Inventory (VisAWI) test for visual experiences from various perspectives were conducted on the developed results. Through these evaluations, users gave positive scores to the design results based on the experience types and essential factors defined in this study. When applying new media technologies such as wearable MR technology, improved technology implementation is important, but an understanding of the applied field must first be obtained, and user analysis must first be thoroughly conducted. This study will be a guide to the systematic development process to be followed when applying wearable MR technology to other fields.

Full textAbstract:
Purpose – Research into the emergence of a hype requires a mixed methods approach that takes into account both the evolution over time and mutual influences across different types of media. The purpose of this paper is to present a methodological approach to detect an emerging hype in online communications. Design/methodology/approach – The paper combines Auto Regressive Integrated Moving Average (ARIMA) time series modelling and semantic co-word networks, and this combination of methods provides a view on the emergence and development of a hype at the level of mutual influences across a heterogeneous set of newspaper and blog data. The subject scope of the paper is the climategate hype. The climategate hype was triggered by the online publication of a set of hacked e-mails belonging to climate researchers at the East Anglia University in November 2009. Findings – The main findings show that the climategate hype was initiated in the blogs, and the newspapers were reacting to the blogs. At the level of semantics, the blogs and the newspapers framed the issue from opposite perspectives. Research limitations/implications – The combination of methods contributes theoretical insights to how blogs interact with more traditional media on hype generation and methodological insights to internet researchers investigating emergent online hypes. The method calls for further validation. Practical implications – Investigating the emergence and evolution of a hype, and the interaction of the two media is relevant for journalists in becoming more reflexive in their practices and the cues from the outside world. Originality/value – The paper is novel in its combination of the two specific methods, ARIMA time series modelling and co-word networks and its attempt to identify the media origins of a hype, and especially the interaction between blogs and newspapers.

Full textAbstract:
In order to enlarge the scale of multimedia communication, based on the design of cloud computing platform, this paper makes an in-depth study on the design of multimedia communication platform. Firstly, we study from three methods: extracting high-quality content, broadening multimedia profit channels, and enhancing copyright awareness. Among them, the big data diversion system under the cloud computing platform is designed to optimize data clustering and pattern recognition. The traditional big data shunting system under the cloud computing platform adopts the open-source embedded system design method. The shunting system is connected to the switch of the cloud computing platform through the coupling coil, resulting in missing points and wrong points in the data in the shunting system. Using this method, it is concluded that the cloud computing platform cannot achieve the optimal allocation in terms of SLA violation rate, resource consumption, and power consumption. After experiments and research, the current development trend of media shows a deviation from this phenomenon. The development of media itself, that is, the self-appreciation of media, is gradually becoming the main purpose of media development. A power simulation cloud computing platform architecture with dynamic expansion, efficient computing, and convenient resource scheduling should be given to face large-scale multimedia communication.

International Journal of Numerical Methods for Heat & Fluid Flow 24, no. 7 (August 26, 2014): 1471–86. http://dx.doi.org/10.1108/hff-07-2012-0169.
Full textAbstract:
Purpose – The purpose of this paper is to present a boundary layer analysis for the mixed convection past a vertical wedge in a porous medium saturated with a power law type non-Newtonian nanofluid. Numerical results for friction factor, surface heat transfer rate and mass transfer rate have been presented for parametric variations of the buoyancy ratio parameter Nr, Brownian motion parameter Nb, thermophoresis parameter Nt, Lewis number Le and the power law exponent n. The dependency of the friction factor, surface heat transfer rate (Nusselt number) and mass transfer rate on these parameters has been discussed. Design/methodology/approach – This general non-linear problem cannot be solved in closed form and, therefore, a numerical solution is necessary to describe the physics of the problem. An implicit, tri-diagonal finite-difference method has proven to be adequate and sufficiently accurate for the solution of this kind of problems. Therefore, it is adopted in the present study. Variable step sizes were used. The convergence criterion employed in this study is based on the difference between the current and the previous iterations. When this difference reached 10−5 for all the points in the η directions, the solution was assumed to be converged, and the iteration process was terminated. Findings – The results indicate that as the buoyancy ratio parameter (Nr) and thermophoresis parameter (Nt) increase, the friction factor increases whereas the heat transfer rate (Nusselt number) and mass transfer rate (Sherwood number) decrease. As the Brownian motion parameter (Nb) increases, the friction factor and surface mass transfer rates increase whereas the surface heat transfer rate decreases. As Le increases, mass transfer rates increase. As the power law exponent n increases, the heat and mass transfer rates increase. Research limitations/implications – The analysis is valid for natural convection dominated regime. The combined forced and natural convection dominated regimes will be reported in a future work. Practical implications – The approach used is useful in optimizing the porous media heat transfer problems in geothermal energy recovery, crude oil extraction, ground water pollution, thermal energy storage and flow through filtering media. Originality/value – The results of the study may be of some interest to the researchers of the field of porous media heat transfer. Porous foam and microchannel heat sinks used for electronic cooling are optimized utilizing the porous medium. The utilization of nanofluids for cooling of microchannel heat sinks requires understanding of fundamentals of nanofluid convection in porous media.

Adults who educate and care for young children are exposed to mixed-messages about what is in the best interests of young children in digital society. Such mixed-messaging makes adult decision-making about technology use in the best interests of young children hard to achieve. This project addresses this problem by working with leading organisations providing services related to quality digital media production, online-safety education, digital play and digital parenting. Using a Participatory Design approach, families, educators, industry partners and researchers will conduct mixed-methods investigations concerning: Relationships; Health and Well-being; Citizenship; and Play and Pedagogy to identify practices concerning technology use ‘with, by and for’ young children. Iterative design cycles will develop an Online Tool to support organisations providing services to young children and the adults responsible for their education and care. As society becomes more digital families and educators need new knowledge about what people do in digital society to inform their decision-making. This project will support organisations to use an empirically informed approach to service provision regarding using technologies in the best interests of young children.
