For rubber-like materials, there are three popular methods of equibiaxial tension available: inflation tension, equibiaxial planar tension, and radial tension. However, no studies have addressed the accuracy and comparability of these tests. In this work, we model the tension tests for a hyperelastic electroactive polymer (EAP) membrane material using finite element method (FEM) and investigate their experimental accuracy. This study also analyzes the impact of apparatus structure parameters and specimen dimensions on experimental performances. Additionally, a tensile efficiency is proposed to assess non-uniform deformation in equibiaxial planar tension and radial tension tests. The sample points for calculating deformation in inflation tensions should be taken near the top of the inflated balloon to obtain a more accurate characteristic curve; the deformation simulation range will be constrained by the material model and its parameters within a specific limit ( ≈ 1.9); if the inflation hole size is halved, the required air pressure must be doubled to maintain equivalent stress and strain values, resulting in a reduction in half in inflation height and decreased accuracy. The equibiaxial planar tension test can enhance uniform deformation and reduce stress errors to as low as 2.1% (at = 4) with single-corner-point tension. For circular diaphragm specimens in radial tension tests, increasing the number of cuts and using larger punched holes results in more uniform deformation and less stress error, with a minimum value of 3.83% achieved for a specimen with 24 cuts and a 5 mm punched hole. In terms of tensile efficiency, increasing the number of tensile points in the equibiaxial planar tension test can improve it; under radial tension, increasing the number of cuts and decreasing the diameter of the punched hole on the specimen has a hedging effect. The findings of this study are valuable for accurately evaluating various equibiaxial tension methods and analyzing their precision, as well as providing sound guidance for the effective design of testing apparatus and test plans.

The legacy effects of invasive plant species can hinder the recovery of native communities, especially under nitrogen deposition conditions, where invasive species show growth advantages and trigger secondary invasions in controlled areas. Therefore, it is crucial to thoroughly investigate the effects of nitrogen deposition on the legacy effects of plant invasions and their mechanisms. The hypotheses of this study are as follows: (1) Nitrogen deposition amplifies the legacy effects of plant invasion. This phenomenon was investigated by analysing four potential mechanisms covering community system structure, nitrogen metabolism, geochemical cycles, and microbial mechanisms. The results suggest that microorganisms drive plant-soil feedback processes, even regulating or limiting other factors. (2) The impact of nitrogen deposition on the legacy effects of plant invasions may be intensified primarily through enhanced nitrogen metabolism via microbial anaerobes bacteria. Essential insights into invasion ecology and ecological management have been provided by analysing how nitrogen-fixing bacteria improve nitrogen metabolism and establish sustainable methods for controlling invasive plant species. This in-depth study contributes to our better understanding of the lasting effects of plant invasions on ecosystems and provides valuable guidance for future ecological management.

Review
Addressing education and employment outcomes in the provision of healthcare for young people with physical long-term conditions: A systematic review and mixed methods synthesis.
OBJECTIVE
To identify and synthesise the experiences and benefits of addressing vocational issues in the provision of healthcare for young people (YP) with long-term conditions (LTCs).
METHODS
We searched 10 bibliographic databases. Restrictions were applied on publication date (1996-2020) and language (English). Two reviewers independently screened records against eligibility criteria. Articles reporting relevant qualitative and/or quantitative research were included. Quality appraisal was undertaken following study selection. Qualitative data were synthesised thematically, and quantitative data narratively. A cross-study synthesis integrated qualitative and quantitative findings.
RESULTS
43 articles were included. Thematic synthesis of qualitative studies (n = 23) resulted in seven recommendations for intervention (psychological support; information/signposting; skills training; career advice; healthcare-school/workplace collaboration; social support; flexible/responsive care). The narrative synthesis summarised results of 17 interventions (n = 20 quantitative studies). The cross-study synthesis mapped interventions against recommendations. Transitional care was the intervention type that most comprehensively met our proposed recommendations.
CONCLUSIONS
Evidence from YP perspectives highlights that vocational development is an important area to address in healthcare provision. Robust intervention studies in this area are lacking.
PRACTICE IMPLICATIONS
Our evidence-based recommendations for intervention can support health professionals to better address vocational issues/outcomes. With minimal adaptations, transitional care interventions would be particularly well suited to deliver this.

Review
OBJECTIVE
The objective of this review was to identify the literature and map the individual and environmental factors that influence registered nurses' and midwives' decision to stay or leave their professions within the first 3 years of practice.
INTRODUCTION
Nursing and midwifery workforce sustainability is an international concern. One aspect is the retention of new registered nurses and midwives in their first years of practice. Several factors are thought to influence the decisions of new registered nurses and midwives to leave or stay in their professions. This review sought to identify and map those factors to enable further research for workforce sustainability development strategies.
INCLUSION CRITERIA
The study cohort included registered nurses and midwives in their first 3 years of practice, which we called newcomers . Nurses who were required to work under the supervision of registered nurses and midwives (ie, enrolled nurses, licensed practical nurses, and licensed vocational nurses) were excluded. Papers were included only if they explored individual or environmental factors influencing nurses' decision to stay in or leave the professions of nursing or midwifery. Studies could be from any country or care environment, and participants were newcomers providing direct clinical care. Newcomers employed in other health roles, such as education, research, administration, or non-nursing/midwifery roles, were excluded. All research designs and peer-reviewed papers were included; policy documents were excluded. The date of inclusion was from the earliest publication on this topic, which was 1974, to the date of the search.
METHODS
The JBI methodology for scoping reviews was followed, and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidance. The search strategy aimed to locate published and unpublished primary studies, reviews, and text and opinion papers. The initial search of relevant databases was conducted in January 2020 and updated in January 2022. Reference lists of included articles were also screened. Following data extraction, descriptive qualitative content analysis was undertaken.
RESULTS
Twelve articles from 11 studies were included in this review. They were published between 2005 and 2020, and originated from 5 countries. Two studies were observational, 3 were cross-sectional, 5 were longitudinal studies, 1 was a pre- and post-program evaluation, and 1 was a scoping review. All studies focused on registered nurses; no publications on registered midwives met the inclusion criteria. Individual factors we identified that impact newcomers' intention to stay in or leave the profession included physical and psychological health, professional identity, professional commitment, and development. Environmental factors included workplace culture, engagement, and management.
CONCLUSIONS
Professional self-image, identity, and a sense of pride in the profession are important components of newcomer retention. Strategies that positively support transition to practice and create realistic expectations were highlighted. Managers play an important role in registered nurse retention, as they can influence many of the newcomers' experiences. It is concerning that no studies about newcomer midwives were found. Many studies explored turnover or intention to leave the job/employer rather than the profession. These are important considerations for future research.

The rapid growth of on-demand ride service platforms has made it increasingly important for these platforms to efficiently match services by understanding driver characteristics and consumer preferences. This paper aims to investigate the pricing strategy by considering the impact of consumer preference heterogeneity and the different service types offered by drivers. The findings of this study reveal the need for the platform to strike a balance between service cost and the benefits of high-quality drivers, which can be referred to as the "cost-performance ratio". If the "cost-performance ratio" that attracts high-quality drivers is high, the platform will attract high-quality drivers or drivers of all types to participate while offering differentiated services. Otherwise, the platform will only provide services through low-quality drivers. Furthermore, the platform will also consider when to offer differentiated services based on network externalities and service quality. When the network externalities of the two types of services are similar, the platform will differentiate them based on service quality differences. Overall, considering consumer preference heterogeneity, drivers of service types, and network externalities, this paper provides guidance for platforms to make optimal decisions that enhance their service offerings and improve overall customer satisfaction.

BACKGROUND
People living with cardiovascular diseases (CVD) often experience work participation problems. Good work-focused healthcare, defined as the received advice, treatment, and guidance focusing on work participation, can support the patient and work place. However, experiences with work-focused healthcare are generally not always positive which is a barrier for work participation. Therefore, the objective of this study is to gain insight into the work-focused healthcare journey from the perspective of patients with work participation problems due to CVD, to understand their experiences and needs, and to derive opportunities for improving work-focused healthcare service at a system level.
METHODS
Semi-structured interviews, preceded by preparatory assignments, were conducted with 17 patients who experience(d) work participation problems due to CVD. The patient experience journey map (PEJM) approach was used to visualize the patients' work-focused healthcare journey, including experiences and needs over time and place, from which opportunities to improve work-focused healthcare from the patient's perspective were derived.
RESULTS
An aggregated PEJM consisting of six phases was composed and graphically mapped. The first phase, working, represents a period in which CVD health problems and subsequent functional limitations occur. The next two phases, short- and long-term sick leave, represent a period of full sick leave. The last three phases, start-, partial-, and full vocational reintegration, focus on the process of return to work that takes place ranging from a few months up to several years after sick-listing. For each phase the touchpoints, timespan, stakeholders, activities, experiences and needs from the perspective of the patients were identified. Finally, for better work-focused healthcare nine opportunities for improvement were derived from the PEJM, e.g. emphasize the need for work adjustment prior to the medical intervention, provide more personalized advice on handling work limitations, and putting more compelling pressure on the employer to create suitable work positions for their employees.
DISCUSSION/CONCLUSION
This paper contributes insights to provide a more patient-centered work-focused healthcare trajectory for patients employed in paid jobs when living with CVD. The PEJM provides an understanding of the patients' perspectives throughout their work-focused healthcare journey and highlights opportunities for improvement towards a better suited and seamless patient journey, Although this research was conducted within the Dutch healthcare system, it can be assumed that the findings on integrated work-focused healthcare are largly transferable to other healthcare systems.

INTRODUCTION
The use of e-cigarettes has steadily increased, and vocational students are one primary target of e-cigarette marketing. This cross-sectional survey research aimed to explore e-cigarette use and examine the factors associated with it.
METHODS
Multistage cluster random sampling was employed to select 1536 students in vocational education institutions. A self-administered questionnaire was used to collect the data from September to December 2019. Multinomial logistic regression analysis was used to obtain the adjusted odds ratio (AOR) to determine the associated factors of e-cigarette use.
RESULTS
Altogether, 28.7% of the subjects were currently e-cigarette users, 7.4% used e-cigarettes only, and 21.3% were dual users. Various factors were found to be significantly associated with e-cigarette use by 43.7%. Those consisted of sex (male) (AOR=2.183; 95% CI: 1.510-3.157), grade point average (GPA) of <2.5 (AOR=2.363; 95% CI: 1.502-3.717), having neutral attitudes toward e-cigarette use (AOR=2.676; 95% CI: 1.499-4.779) and positive attitudes toward e-cigarette use (AOR=4.171; 95% CI: 2.250-7.734), moderate level of perceived behavioral control on e-cigarette use (AOR=3.520; 95% CI: 2.287-5.418) and low level of perceived behavioral control on e-cigarettes use (AOR=4.959; 95% CI: 3.274-7.511), moderate price of e-cigarettes (AOR=1.436; 95% CI: 1.009-2.044), and e-cigarette use of their parents (AOR=1.827; 95% CI: 1.137-2.938), close friends (AOR=4.327; 95% CI: 2.954-6.338) and idols (AOR=4.604; 95% CI: 1.844-11.497).
CONCLUSIONS
Students should be encouraged to develop negative attitudes toward e-cigarette use and increase their self-confidence to control the use of e-cigarettes. This can be achieved by regularly distributing information on the product's risks. Moreover, students can find inspiration and guidance from peers, close friends, or their idols, who will act as positive role models and inspire them not to initiate e-cigarette use.

Review
Components of Outpatient Child and Youth Concurrent Disorders Programs: A Critical Interpretive Synthesis: Composantes des programmes de troubles concomitants des enfants et des jeunes ambulatoires : une synthèse interprétative critique.
OBJECTIVE
Co-occurring mental health and substance use disorders (concurrent disorders) lead to significant morbidity in children and youth. Programs for integrated treatment of concurrent disorders have been developed; however, there exists little guidance outlining their structure and activities. Our objective was to synthesize available information on outpatient child and youth concurrent disorders programs and produce a comprehensive framework detailing the components of such programs.
METHODS
We used a four-stage critical interpretive synthesis design: (1) systematic review of published and grey literature, (2) data abstraction to identify program components and purposive sampling to fill identified gaps, (3) organization of components into a structured framework, (4) feedback from programs. We employed an iterative process by which programs reviewed data abstraction and framework development and provided feedback.
RESULTS
Through systematic review (yielding 1,408 records total and 7 records eligible for inclusion) and outreach strategies (yielding an additional 7 eligible records), we identified 11 programs (4 American, 7 Canadian) and 2 theoretical models from which data could be abstracted. Program activities were categorized into 12 overarching constructs that make up the components of the framework: accessibility, engagement, family involvement, integrated assessment, psychotherapy for patients, psychotherapy for families, medication management, health promotion, case management, vocational support, recreation and social support, and transition services. Program components are informed by the philosophical orientation of the program and models of care. This framework considers health system factors, clinical service factors, program development, and community partnership that impact program structure and activities. Multidisciplinary teams provide care and include addiction medicine, psychiatry, psychology, nursing, social work, occupational therapy, recreation therapy, peer support, and program evaluation.
CONCLUSION
We developed a comprehensive framework describing components of child and youth outpatient concurrent disorders programs. This framework may assist programs currently operating, and those in development, to reflect on their structure and activities.

In order to study the effects and mechanism of Monascus on the quality of hairtail surimi, high-throughput sequencing technology, headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC/MS), and electronic nose techniques were used to investigate the changes in the quality, microbial diversity, and volatile flavor compounds of Monascus-fermented hairtail surimi (MFHS) during fermentation. The results showed that the total volatile basic nitrogen (TVB-N) index of hairtail surimi fermented by Monascus for 0-5 h met the requirements of the national standard. Among them, the 1 h group showed the best gel quality, which detected a total of 138 volatile substances, including 20 alcohols, 7 aldehydes, 12 olefins, 4 phenols, 12 alkanes, 8 ketones, 15 esters, 6 acids, 16 benzenes, 4 ethers, and 8 amines, as well as 26 other compounds. In addition, the dominant fungal microorganisms in the fermentation process of MFHS were identified, and a Spearman correlation analysis showed that 16 fungal microorganisms were significantly correlated with the decrease in fishy odor substances in the fermented fish and that 8 fungal microorganisms were significantly correlated with the increase in aromatic substances after fermentation. In short, Monascus fermentation can eliminate and reduce the fishy odor substances in hairtail fish, increase and improve the aromatic flavor, and improve the quality of hairtail surimi gel. These findings are helpful for revealing the mechanism of the quality formation of fermented surimi and provide guidance for the screening of starter culture in the future.

BACKGROUND
Despite the increasing incidence of aplastic anemia in China, few studies have explored its effect on the patients' quality of life from the perspective of these patients. In fact, patients with aplastic disorder live with the disease for a long time, and need to face a variety of difficult realities, including multiple disease symptoms and drug side effects, heavy burden of medical costs, difficulties in social reintegration, and negative emotional distress. Therefore, this study used descriptive qualitative research to explore the direct and rich quality-of-life experiences of patients with aplastic anemia.
METHODS
A total of 19 patients with aplastic anemia were recruited in this study using purposive sampling combined with maximum variation strategy. 5 of the patients with AA were from northern China, and the others were from southern China. Data were collected using semi-structured interviews and analyzed using the conventional content analysis method.
RESULTS
This study yielded important information about the experiences of patients with aplastic anemia in China. The content analysis method finally identified 3 themes and 9 sub-themes, including: physical symptoms (declining physical capacity, treatment-related symptoms, changes in body image), psychological symptoms (mood changes related to the stage of the disease, change in self-image, growth resulting from the disease experience), social burden (decline in career development, perceived burden to the family, social stigma). Patients with AA from different regions didn't show much difference in quality of life.
CONCLUSIONS
Aplastic anemia affects the physical, psychological, and social aspects of patients' lives. Therefore, health care providers need to consider the patients' physical response and psychological feelings to provide relevant medical guidance and multi-channel social support that would improve their confidence and quality of life.
