Nursing students' work readiness and its influencing factors before participating in a nurse residency program: a multicenter cross-sectional study.

Studies have shown that work readiness is closely related to nurses' role adaptation, career development, and patient safety. However, we know little about the nursing students' work readiness and its influencing factors before participating in a nurse residency program, and whether factors have changed from before. (1) To investigate the work readiness of nursing students ready to engage in a nurse residency program; (2) to identify the factors affecting the nursing students' work readiness and the associations between emotional intelligence and work readiness; and (3) to discuss the changes of factors affecting nursing students' work readiness. An online, multicenter cross-sectional study. 878 nursing students from eight tertiary hospitals in Chongqing, China were recruited. The online investigation used the General Information Questionnaire, the Nursing Students' Work Readiness Scale, and the Emotional Intelligence scale. The data were analyzed using IBM SPSS V23.0. 768 valid questionnaires were included in this study. The nurses obtained a work readiness score of 277.08 ± 44.39 and an emotional intelligence score of 89.57 ± 13.89. Univariate analysis revealed that the following factors affected work readiness: age, sex, family support for becoming a nurse, voluntary choice of nursing major, previous experience as a student cadre, scholarship recipient status, willingness to engage in nursing work during the COVID-19 pandemic and confidence in clinical nursing practice. Frequent incidents of violence, poor salary for nurses for the nurse residency program, and low social acceptance were the top three reasons for decreased confidence in clinical nursing among nursing students. Furthermore, multiple linear regression analysis indicated that age, voluntary choice of nursing major, student leadership experience, confidence in clinical nursing work, self-emotion, and emotional application significantly influenced nurses' work readiness. Clinical instructors and administrators should dynamically assess nurses' work readiness, prioritize individuals aged ≤23, who have chosen the nursing profession involuntarily, lack prior experience as student cadres, and exhibit low confidence in clinical nursing work. This focus will enhance their emotional self-management skills and ability to apply emotions effectively, improving their work readiness and training efficacy.

Global prevalence and determinants associated with the acceptance of monkeypox vaccination.

Assessing the acceptance of the monkeypox vaccine is crucial for the success of vaccination programs, yet the prevalence reports remain inconclusive. The aim of this study was to determine the global prevalence of monkeypox vaccine acceptance and identify its associated factors. A meta-analysis was conducted with a comprehensive search strategy on the following databases, including Scopus, Embase, and PubMed, for articles published up to April 5, 2024. This study utilizes a single-arm meta-analysis to calculate the pooled prevalence of monkeypox vaccine acceptance. A Z-test was employed to identify factors associated with the vaccine acceptance. Our study analyzed 51 articles encompassing 98,746 participants, revealing an overall monkeypox vaccine acceptance rate of 65%. Notably, the highest acceptance rates were observed among men who have sex with men (MSMs), while healthcare workers (HCWs) showed the lowest acceptance rates. Additionally, our findings indicated an increased acceptance in individuals with educational attainment beyond a bachelor's degree, a history of COVID-19 and influenza vaccination, homosexual orientation, and HIV-positive status. Conversely, lower acceptance risk was associated with those with educational attainment below a bachelor's degree, heterosexual orientation, and bisexual orientation. In conclusion, our current study has determined the rate of monkeypox vaccine acceptance and identified its associated factors. These findings offer valuable insights as the foundation for targeted policies to manage and increase acceptance rates.

COVID-19 vaccination hesitance and adverse effects among US adults: a longitudinal cohort study.

Although Coronavirus disease 2019 (COVID-19) vaccination is critical to control its spread, vaccine hesitancy varies significantly among the United States population; moreover, some vaccine recipients experienced various adverse effects. We aim to assess the impact of COVID-19 vaccine hesitancy in a university-affiliated community, the factors affecting participants' decisions, and their adverse effects. A pre-vaccination online Institutional Review Board IRB-approved survey was emailed in Nov/Dec 2020, 2 months before the implementation of state-policy protocols for COVID-19 vaccination. A post-vaccination survey was emailed in May/June 2021, two months after protocol execution. A third follow-up survey was sent in Nov/Dec 2021, and a fourth was sent in June/July 2022. The study population included three groups of adult participants: university students, faculty, and staff-(MS), university health system patients-(MP), and Cancer Center patients-(MCP). The study was designed as a longitudinal cohort study. Statistical analyses were performed using SPSS. With a combined response rate of 26% (40,578/157,292) among the four surveys, 15,361 participants completed the first survey (MS = 4,983, MP = 9,551, and MCP = 827). 2/3 of participants (63.5%) were willing to get vaccinated, with a significant difference in acceptance among groups, MS:56.6%, MP:66.2%, and MCP:71.6% (p < 0.05). Vaccine acceptance rates reached 89% in the second survey after the vaccine's approval, with a lower acceptance rate of MS:84.6% than with MP:90.74% and MCP:92.47% participants (p < 0.05). Safety and effectiveness concerns were the main factors affecting participants' decisions in all the first three surveys; however, participants reported these concerns decreased between pre-vaccination, post-vaccination, and follow-up surveys with 87%, 56%, and 46%, respectively(p < 0.05). More than two-thirds of the participants (70%) reported having either minor/moderate symptoms (61.6%) or major symptoms (8.6%) after getting some of the vaccine doses (p < 0.05). The hesitance of COVID-19 vaccination was associated with concerns regarding its safety and efficacy. Vaccine acceptance rose higher than expected after protocol execution, likely due to continuous education, whereas safety and efficacy remain factors hindering vaccine acceptance. Continuous education focusing on safety and efficacy of the vaccine can reduce vaccine hesitancy and raise the rates of vaccination.

Network dynamics of self-compassion, anxiety, and depression during eating disorder therapy.

Recovery processes during residential treatment for eating disorders, especially in patients with a history of maltreatment, are insufficiently understood. This study aimed to explore the temporal relationships among comorbid factors, including depression, anxiety, and self-compassion, with the influence of childhood maltreatment. Using Dynamic Time Warp (DTW), weekly scores from the Symptom Checklist-5, Eating Disorder Examination, and Self-Compassion Scale were analysed over 12weeks. The study generated undirected and directed networks to identify influential symptoms in a transdiagnostic sample, comparing patients with and without childhood maltreatment. The study included 124 patients with eating disorders (ED) (97% women), mean age of 30.9years (SD=9.7, range 18-61years). Diagnoses included anorexia nervosa (26%), bulimia nervosa (38%), and other specified feeding and eating disorders (36%). The directed DTW network showed that hopelessness, worrying, and restlessness had the highest out-strength, predicting changes in self-compassion and ED behaviour. In maltreatment cases, hopelessness and low acceptance predicted changes, while worry, restlessness, and nervousness were predictive in non-maltreatment cases. Temporal network analyses suggest that a change in hopelessness, worrying, and restlessness drives symptom improvement in ED behaviour and the development of self-compassion during residential treatment. These processes vary between patients with and without a history of childhood maltreatment separately, indicating the need for further analyses.

Quantifying the Wild: Public Acceptance and Challenges of Urban Wildscapes in Chiba, Japan

People’s reduced connection with nature has led to many health problems. In the NBS framework, urban wildscapes (UWSs) are considered an important solution. They can contribute to improving the health of residents and ecosystems within the city. However, overly wild green spaces may also be offensive to residents. It is necessary to understand the public’s acceptance of UWSs. Current studies on the acceptance of UWSs have used vague terms to generalize the “wildness degree”. In this study, we attempted to quantify the degree of wildness using plant height and plant abundance in Japan and analyzed the results through mediated effect analysis. We discovered the following: 1. Japanese residents have low acceptance of UWSs in vacant lots. 2. The use of “height” and “abundance” may be a more objective way to quantify wildness. 3. The negative effects of abundance can be minimized. The negative effect of height cannot be controlled. This study addresses a gap in the study of Asian cities and proposes a novel approach to quantifying “wildness.” It improves the health benefits of UWSs. Furthermore, it can offer guidance on the management and construction of urban green spaces.

Acceptability of Medical Male Circumcision as an HIV Prevention Intervention among Male Learners in a South African High School.

Circumcision is a long-standing and frequently performed surgical procedure which holds significant cultural significance among AmaXhosa people in South Africa. Due to cultural reasons in some parts of Africa, the integration of medical male circumcision with traditional manhood initiation rituals still lacks acceptance. This study examined the level of knowledge and acceptance of voluntary male medical circumcision (VMMC) among young males in a selected high school in the Nyandeni District of the Eastern Cape Province, South Africa. A descriptive, quantitative, cross-sectional study was conducted, and a self-administered questionnaire was used to obtain information on sociodemographic characteristics, knowledge of VMMC, perceptions of VMMC, and circumcision practices. One hundred participants were recruited from both grades 11 and 12, and 82% of the participants indicated that they had received information about VMMC. Most of the respondents (88%) preferred traditional male circumcision (TMC), and only 12% of respondents preferred VMMC. The participants displayed a good understanding of the distinction between VMMC and TMC. However, results from the study showed that most respondents exhibited low acceptability and knowledge towards VMMC. These findings highlight the need to develop evidence-based strategies to enhance learners' knowledge and acceptance of VMMC.

Predictors of COVID-19 vaccine acceptability among refugees and other migrant populations: A systematic scoping review.

This study aimed to map the existing literature to identify predictors of COVID-19 vaccine acceptability among refugees, immigrants, and other migrant populations. A systematic search of Medline, Embase, Scopus, APA PsycInfo and Cumulative Index of Nursing and Allied Health Literature (CINAHL) was conducted up to 31 January 2023 to identify the relevant English peer-reviewed observational studies. Two independent reviewers screened abstracts, selected studies, and extracted data. We identified 34 cross-sectional studies, primarily conducted in high income countries (76%). Lower vaccine acceptance was associated with mistrust in the host countries' government and healthcare system, concerns about the safety and effectiveness of COVID-19 vaccines, limited knowledge of COVID-19 infection and vaccines, lower COVID-19 risk perception, and lower integration level in the host country. Female gender, younger age, lower education level, and being single were associated with lower vaccine acceptance in most studies. Additionally, sources of information about COVID-19 and vaccines and previous history of COVID-19 infection, also influence vaccine acceptance. Vaccine acceptability towards COVID-19 booster doses and various vaccine brands were not adequately studied. Vaccine hesitancy and a lack of trust in COVID-19 vaccines have become significant public health concerns within migrant populations. These findings may help in providing information for current and future vaccine outreach strategies among migrant populations.

Cross-cultural comparison of the acceptance of insects as food among young adults in Malaysia and Japan

Abstract The growing world population raises concerns about food security, with increasing demand for animal protein often impacting scarce resources like land, water and energy. Edible insects have been proposed as an alternative protein source to address this issue. The study aimed to compare acceptance of insects as food and its association with food neophobia among young adults in Malaysia and Japan. A cross-sectional study was conducted among 1954 subjects, comprising 1,071 Malaysians and 883 Japanese young adults. Subjects completed an online questionnaire on sociodemography, Food Neophobia Scale, and acceptance of insects as food. Chi-square, Wilcoxon signed rank post-hoc and Mann-Whitney U tests were used for statistical analysis. Only 9.2% were willing to eat insects as food and 6.5% were ready to adopt eating insects in daily life. A higher proportion of Malaysians (10.5%) was willing to accept insects as food than Japanese (7.6%, ). However, Japanese (9.5%) were more ready to adopt eating insects in daily life than Malaysians (3.9%, ). Most subjects in both countries were in the neutral category of food neophobia, with no significant difference between countries. In Malaysia, the main reason for willingness to eat insects was food safety (11.5%), while in Japan it was caloric and nutritional value (17.8%). The main reason for unwillingness to eat insects in both countries was appearance (Malaysia: 17.1%; Japan: 27.9%). There was a significant association () between the acceptance of insects as food and the category of food neophobia, with lower acceptance associated with higher neophobia or vice versa. In conclusion, the acceptance of insects as food is low among young adults in Malaysia and Japan. A strategic marketing approach tailored to the reasons for acceptance could effectively promote entomophagy in both countries. Further studies should focus on transforming insects into more palatable forms.

Efficacy of Traditional Acupuncture Compared to Biofeedback Therapy in Fecal Incontinence: A Randomized Controlled Trial.

Fecal incontinence has a devastating impact on quality of life and imposes a substantial socioeconomic burden. Best medical therapy, including biofeedback therapy, improves mild symptoms with minimal impact on moderate to severe symptoms. Surgical management for incontinence carries a degree of morbidity, resulting in low uptake and acceptability. Although acupuncture is common practice in Singapore for numerous medical conditions, its role in fecal incontinence is relatively novel. In our local context, however, acupuncture is accessible, inexpensive, and potentially well accepted as a treatment strategy. To determine the effectiveness of traditional Chinese medicine acupuncture, compared to biofeedback therapy, in the treatment of fecal incontinence. The secondary aim is to investigate the differences in quality of life after treatment. Randomized controlled trial. Prospective, single-institution study. Patients with 2 or more episodes of fecal incontinence per week or St. Mark's incontinence score of 5 or higher were recruited. Patients were randomly assigned into biofeedback therapy, which included 3 sessions over 10 weeks, or 30 sessions of acupuncture over 10 weeks. Incontinence episodes, St. Mark's score, and fecal incontinence quality-of-life scale. Eighty-five patients were randomly assigned to biofeedback therapy (n = 46) or acupuncture (n = 39). Demographics and baseline clinical characteristics were not different ( p > 0.05). Overall median incontinence episodes were reduced in both, with the acupuncture arm reporting significantly fewer episodes at week 15 ( p < 0.001). Acupuncture also improved quality of life, with improvement in lifestyle, coping, depression, and embarrassment at week 15 ( p < 0.05). Although the St. Mark's score was significantly reduced in both arms at week 15 ( p < 0.001), the acupuncture arm's score was significantly lower ( p = 0.002). Longer follow-up is required. Acupuncture is clinically effective and improves the quality of life in patients with fecal incontinence. See Video Abstract . Clinicaltrials.gov : NCT04276350. ANTECEDENTES:La incontinencia fecal tiene un impacto devastador en la calidad de vida e impone una carga socioeconómica sustancial. La mejor terapia médica, incluida la terapia de biorretroalimentación, mejora los síntomas leves, con un impacto mínimo sobre los síntomas moderados a graves. El tratamiento quirúrgico de la incontinencia conlleva un grado de morbilidad que resulta en una baja aceptación y aceptabilidad. Si bien la acupuntura es una práctica común en Singapur para numerosas afecciones médicas, su papel en la incontinencia fecal es relativamente novedoso. Sin embargo, en nuestro contexto local, la acupuntura es accesible, económica y potencialmente bien aceptada como estrategia de tratamiento.OBJETIVO:Determinar la efectividad de la acupuntura de la Medicina Tradicional China, en comparación con la terapia de biorretroalimentación en el tratamiento de la incontinencia fecal. El objetivo secundario es investigar las diferencias en la calidad de vida después del tratamiento.DISEÑO:Ensayo controlado aleatorio.AJUSTE:Estudio prospectivo de una sola institución.PACIENTES:Se reclutaron pacientes con >2 episodios de incontinencia fecal/semana o una puntuación de incontinencia de St. Mark's >5. Los pacientes fueron asignados aleatoriamente a una terapia de biorretroalimentación que incluyó 3 sesiones durante 10 semanas o 30 sesiones de acupuntura durante 10 semanas.PRINCIPALES MEDIDAS DE RESULTADO:Episodios de incontinencia, puntuación de St. Mark's y escala de calidad de vida de incontinencia fecal.RESULTADOS:Ochenta y cinco pacientes fueron asignados aleatoriamente a terapia de biorretroalimentación (n = 46) o acupuntura (n = 39). Las características demográficas y clínicas iniciales no fueron diferentes ( p > 0,05). La mediana general de episodios de incontinencia se redujo en ambos, y el grupo de acupuntura informó significativamente menos en la semana 15 ( p <0,001). La acupuntura también mejoró la calidad de vida, con mejoras en el estilo de vida, el afrontamiento, la depresión y la vergüenza en la semana 15 ( p <0,05). Mientras que la puntuación de St Mark se redujo significativamente en ambos brazos en la semana 15 ( p < 0,001), la puntuación del brazo de acupuntura fue significativamente menor (p = 0,002).LIMITACIONES:Se requiere un seguimiento más prolongado.CONCLUSIONES:La acupuntura es clínicamente efectiva y mejora la calidad de vida en pacientes con incontinencia fecal.

Environmental Analysis and Management Suggestions of Starbucks Based on SWOT Model

We analyzed the advantages and disadvantages of Starbucks environmental scanning. Its advantage is the high quality of the product, and the third aspect is the strong sense of experience, the advantage of social media, and localized marketing. The disadvantages are high product positioning, fast store opening, and the pressure of financial chain management and supply chain management. However, in our survey, we also identified opportunities to expand online sales and mobile payments to maximize benefits in today's globalized world. However, despite Starbucks' growth prospects, its position is now precarious due to low coffee acceptance and threats from coffee brands such as Lucky Coffee. According to the analysis, Starbucks can improve its current weakness by strengthening its market power, expanding its strategy, differentiating its strategy, and adopting a reasonable and flexible pricing system.

Public attitudes to xenotransplantation: A national survey in the United States

Xenotransplantation (XTx) presents a potential clinical alternative to the shortage of human organs for transplantation. Before clinical trials occur in the United States, public assessments are crucial to understand potential barriers to acceptance. The purpose of this study was to explore barriers and identify characteristics associated with attitudes toward XTx. A survey assessing demographic characteristics and attitudes toward XTx was distributed to a nationally representative sample of adults aged ≥18 years in the United States. Regression analysis was employed to identify characteristics associated with attitudes toward XTx. Between May 25 and June 14, 2023, 5008 respondents completed the survey. Importantly, half of the respondents expressed low or no knowledge of either transplantation or XTx. Approximately 40% expressed discomfort with receiving a pig organ for themselves or a loved one. Despite a lack of xenotransplant outcome data, 36% were open to experimental XTx if they needed a transplant. However, 57% rated lack of current evidence of success or fear of complications as top concerns. Regression models consistently associated being younger, female, not needing an organ, or being a member of a racial minority group with lower acceptance. This survey is the largest to date exploring public attitudes toward XTx. Despite overall acceptance, concerns persist. Increasing public acceptance is key as the field advances.

The Use of a Tailored Decision Aid to Improve Understanding of Lung Cancer Screening in People With HIV

People with HIV are at increased risk for lung cancer and multimorbidity, complicating the balance of risks and benefits of lung cancer screening. We previously adapted Decision Precision (screenlc.com) to guide shared decision-making for lung cancer screening in people with HIV. Does an HIV-adapted and personally tailored decision aid improve shared decision-making regarding lung cancer screening in people with HIV as measured by knowledge, decisional conflict, and acceptability? This was a single-arm pilot trial of the decision aid in 40 participants with HIV eligible for lung cancer screening. The decision aid included personalized screening recommendations and HIV-specific, five-year risk estimates of lung cancer and all-cause mortality. Participants reviewed the decision aid at shared decision-making visits and completed pre- and post-visit surveys with measures of knowledge about lung cancer screening, acceptability, and decisional conflict. The 40 enrolled participants were a median 62 years old and 60% were currently smoking with median five-year risks of lung cancer and all-cause mortality of 2.0% (IQR 1.4-3.3%) and 4.1% (IQR 3.3-7.9%). Personalized recommendations included "Encourage Screening" for 53% of participants and "Preference Sensitive" recommendations for the remainder. Participants showed improvement in two validated knowledge measures with relative improvement of 60% (p<0.001) on the LCS-12 and 27% (p<0.001) on the LKS-7, with significant improvement on questions regarding false-positive and false-negative findings, incidental findings, lung cancer-specific mortality benefit, and the possible harms of screening. Participants reported low scores on the decisional conflict scale (median score 0, IQR 0-5) and high acceptability. Ninety percent ultimately underwent screening within one month of the visit. This HIV-adapted and personally tailored decision aid improved participants' knowledge of risks, benefits, and characteristics of screening with low decisional conflict and high acceptability. This decision aid can enable high-quality shared decision-making in this high-risk population.

Depression screening in patients with coronary heart disease : Anarrative review of the current evidence.

In view of the large and sometimes conflicting body of research, this narrative review summarizes the current evidence on depression screening in patients with coronary heart disease. Depression is arisk factor for development and progression of coronary heart disease. Consequently, many international cardiac guidelines recommend screening for depression in patients with coronary heart disease. However, the efficacy and implementation of these guidelines are debated due to the lack of empirical evidence supporting the benefits of routine depression screening. Studies conducted in cardiac routine care support this assumption: Patients with positive depression screens do not receive adequate follow-up care, which highlights gaps in the detection-to-treatment pathway. Barriers to effective screening and treatment include system-level factors, such as insufficient integration of mental health resources in cardiology, and patient-related factors like stigma and low acceptance of mental health treatment. Innovative interventions that address these barriers and involve patients as active partners in depression care should be developed through atheory-driven, transparent, multistage process involving key stakeholders such as patients, nurses, and cardiologists. Asound methodological evaluation of such multilevel interventions could answer the question of whether early detection of depression in patients with coronary heart disease would lead to health benefits.

Treatment acceptance in adult patients with anterior open bite: A National Dental Practice-Based Research Network study

Orthodontists have many techniques to treat anterior open bites and must involve patients in making treatment decisions. This study aimed to investigate orthodontic treatment plan acceptance by United States adults with anterior open bites and to identify associations between treatment acceptance and patient demographics and dentofacial characteristics. A prospective, observational cohort study enrolled the patients of 91 orthodontic providers. A total of 345 adults were included in the sample. Provider personal and practice demographics were captured. Patient demographics, treatment goals, dentofacial characteristics, and reasons for not accepting the recommended plans were recorded. Adjusted regression models were used to identify associations between patient characteristics and the likelihood of accepting the most highly recommended plan. Approximately 78% of patients accepted the most highly recommended treatment plan. 60% of the patients who were recommended surgical plans accepted them. Patients with a history of orthodontics and a concave profile were more likely to accept the most highly recommended plan. Insurance coverage for orthognathic surgery was associated with a higher acceptance rate for surgery. Severe crowding was associated with a lower acceptance of surgery. The most common reasons for declining the recommended plan were not wanting jaw surgery and considering the treatment to be too invasive, risky, and/or costly. Patient acceptance is less common at higher levels of invasiveness of treatment. Prior orthodontic treatment, concave profile, and insurance coverage for surgery were associated with accepting treatment. Most patients accepted a surgical plan when it was the most recommended option.

Glass Defect Detection with Improved Data Augmentation under Total Reflection Lighting

To address the technical challenge of identifying tiny defects, especially dust and point defects, on mobile phone flat glass, an automatic optical inspection system is established. The system investigates algorithms including imaging principles, target detection models, data augmentation, foreground segmentation, and image fusion. The system builds an automatic optical inspection platform to collect glass defect samples. It illuminates the glass samples with a combined total reflection–grazing light source, collects the defect sample data, segments the background and defects of the collected data, generates the defect mask, and extracts the complete defects of the cell phone flat glass. The system then seamlessly integrates the extracted defects with a flawless background using Poisson editing and outputs the location information of the defects and the label output to automatically generate the dataset. The deep learning network YOLOv5 works as the core algorithm framework, into which the Constructive Block Attention Module and the small target detection layer are specifically added to enhance the capability of the model to detect small defects. According to the experimental results, the combined lighting effectively improves the precision of detecting dust and bright spots. Additionally, with the adoption of novel data augmentation techniques, the enhanced YOLOv5 model is capable of effectively addressing the challenges posed by inefficient sample data and non-uniform distribution, thus mitigating network generalization issues. Furthermore, this data augmentation approach facilitates the rapid adaptation of the same detection tasks to diverse environmental scenarios, enabling the expedited and efficient deployment of the model across various industrial settings. The mean average precision (MAP) of the optimal model in the validation set reached 98.36%, 2.62% higher than that of the original YOLOv5. In addition, its false acceptance rate (FAR) is 1.27%, its false rejection rate (FRR) was 2.47%, its detection speed was 64 fps, and its correct detection rate in the validation set was 98.75%, which meets the current industrial detection requirements by and large. In this way, this paper achieved the automated inspection of mobile phone flat glass with high robustness, high precision, and a low false acceptance rate and false rejection rate, significantly reducing material losses in the factories and the likelihood of error occurrence in follow-on products. This method can be applied to the multi-scale and multi-type detection of glass defects.

The Inheritance and Development of Northern Shaanxi Folk Songs in the Era of Big Data

With the arrival of the big data era, the inheritance and development of northern Shaanxi folk songs are facing unprecedented opportunities and challenges. From the perspective of big data, this paper analyses the communication status of northern Shaanxi folk songs in contemporary society, discusses the impact of the big data era on the inheritance and development of northern Shaanxi folk songs, and puts forward a series of innovative inheritance and development strategies. Firstly, this paper gives a brief introduction to the concept and characteristics of the big data era, and elaborates on the historical and cultural value of northern Shaanxi folk songs. Through the data mining of network platforms and field research, the communication characteristics of northern Shaanxi folk songs are analysed, and it is found that its communication channels are wide and the audience groups are diverse, but at the same time, it also faces the dilemma of the traditional inheritance method and the problem of low acceptance of the younger generation. In view of these problems, this paper proposes a series of inheritance and development strategies. In terms of dissemination, it is suggested that new media channels such as digital music platforms and online short videos be used for promotion; in terms of education and training, it is advocated that Shaanxi folk songs be integrated into school music education and professional training courses to cultivate a new generation of Shaanxi folk song inheritors; in terms of artistic innovation, it is encouraged that Shaanxi folk songs be combined with modern art forms, and that new Shaanxi folk songs with the characteristics of the times be created. In order to verify the feasibility of the proposed strategy, this paper selects two successful cases to introduce and analyse, summing up a series of valuable experience. Finally, this paper summarises the whole paper and looks forward to the future inheritance and development of northern Shaanxi folk songs in the era of big data.

Measurement Uncertainty and Risk of False Compliance Assessment Applied to Carbon Isotopic Analyses in Natural Gas Exploratory Evaluation.

The concept of uncertainty in an isotopic analysis is not uniform in the scientific community worldwide and can compromise the risk of false compliance assessment applied to carbon isotopic analyses in natural gas exploratory evaluation. In this work, we demonstrated a way to calculate one of the main sources of this uncertainty, which is underestimated in most studies focusing on gas analysis: the δ13C calculation itself is primarily based on the raw analytical data. The carbon isotopic composition of methane, ethane, propane, and CO2 was measured. After a detailed mathematical treatment, the corresponding expanded uncertainties for each analyte were calculated. Next, for the systematic isotopic characterization of the two gas standards, we calculated the standard uncertainty, intermediary precision, combined standard uncertainty, and finally, the expanded uncertainty for methane, ethane, propane, and CO2. We have found an expanded uncertainty value of 1.8‰ for all compounds, except for propane, where a value of 1.6‰ was obtained. The expanded uncertainty values calculated with the approach shown in this study reveal that the error arising from the application of delta calculation algorithms cannot be neglected, and the obtained values are higher than 0.5‰, usually considered as the accepted uncertainty associated with the GC-IRMS analyses. Finally, based on the use of uncertainty information to evaluate the risk of false compliance, the lower and upper acceptance limits for the carbon isotopic analysis of methane in natural gas are calculated, considering the exploratory limits between -55‰ and -50‰: (i) for the underestimated current uncertainty of 0.5‰, the lower and upper acceptance limits, respectively, are -54.6‰ and -50.4‰; and (ii) for the proposed realistic uncertainty of 1.8‰, the lower and upper acceptance limits would be more restrictive; i.e., -53.5‰ and -51.5‰, respectively.

Effect of alcohol health warning labels on knowledge related to the ill effects of alcohol on cancer risk and their public perceptions in 14 European countries: an online survey experiment

Alcohol health-warning labels are a policy option that can contribute to the reduction of alcohol-related harms, but their effects and public perception depend on their content and format. Our study aimed to investigate the effect of health warnings on knowledge that alcohol causes cancer, the perceptions of three different message topics (responsible drinking, general health harm of alcohol, and alcohol causing cancer), and the role of images included with the cancer message. In this online survey experiment, distributed in 14 European countries and targeting adults of the legal alcohol-purchase age who consumed alcohol, participants were randomly allocated to one of six label conditions using a pseudorandom number generator stratified by survey language before completing a questionnaire with items measuring knowledge and label perceptions. Effect on knowledge was assessed as a primary outcome by comparing participants who had increased knowledge after exposure to labels with the rest of the sample, for the six label conditions. Label perceptions were compared between label conditions as secondary outcomes. 19 110 participants completed the survey and were eligible for analysis. Our results showed that a third of the participants exposed to the cancer message increased their knowledge of alcohol causing cancer (increase for 1131 [32·5%, 95% CI 29·8 to 35·2] of 3409 participants [weighted percentage] for text-only message; increase for 1096 [33·3%, 30·4 to 36·2] of 3198 [weighted percentage] for message inlcuding pictogram; and increase for 1030 [32·5%, 29·6 to 35·4] of 3242 [weighted percentage] for message including graphic image), compared with an increase for 76 (2·4%, -1·2 to 6·0) of 3018 participants who viewed the control message. Logistic regression showed that cancer messages increased knowledge compared with the control label (odds ratio [OR]text only 20·20, 95% CI 15·88 to 26·12; ORpictogram 21·16, 16·62 to 27·38; ORgraphic-image 20·61, 16·19 to 26·68). Cancer messages had the highest perceived impact and relevance, followed by general health harm and responsibility messages. Text-only and pictogram cancer messages were seen as clear, comprehensive, and acceptable, whereas those including an image of a patient with cancer had lower acceptability and the highest avoidance rating of all the labels. The only identified interaction between perceptions and experimental conditions (with gender) indicated higher comprehensibility and acceptability ratings of cancer labels than responsibility messages and control labels by women, with the results reversed in men. Health warnings are an effective policy option to increase knowledge of alcohol causing cancer, with a generalisable effect across several countries. Europeans consider alcohol health-warning labels to be comprehensible and acceptable, with cancer-specific health warnings having the highest perceived impact and relevance. EU4Health.

A computational approach to understanding effort-based decision-making in depression.

Motivational dysfunction is a core feature of depression, and can have debilitating effects on everyday function. However, it is unclear which disrupted cognitive processes underlie impaired motivation, and whether impairments persist following remission. Decision-making concerning exerting effort to collect rewards offers a promising framework for understanding motivation, especially when examined with computational tools which can offer precise quantification of latent processes. Effort-based decision-making was assessed using the Apple Gathering Task, in which participants decide whether to exert effort via a grip-force device to obtain varying levels of reward; effort levels were individually calibrated and varied parametrically. We present a comprehensive computational analysis of decision-making, initially validating our model in healthy volunteers (N=67), before applying it in a case-control study including current (N=41) and remitted (N=46) unmedicated depressed individuals, and healthy volunteers with (N=36) and without (N=57) a family history of depression. Four fundamental computational mechanisms that drive patterns of effort-based decisions, which replicated across samples, were identified: an overall bias to accept effort challenges; reward sensitivity; and linear and quadratic effort sensitivity. Traditional model-agnostic analyses showed that both depressed groups showed lower willingness to exert effort. In contrast with previous findings, computational analysis revealed that this difference was driven by lower effort acceptance bias, but not altered effort or reward sensitivity. This work provides insight into the computational mechanisms underlying motivational dysfunction in depression. Lower willingness to exert effort could represent a trait-like factor contributing to symptoms, and might represent a fruitful target for treatment and prevention.

Perspectives on challenges to bioenergy use in the EU

AbstractDespite bioenergy playing an important role in producing a significant amount of renewable energy in the EU, there are several differing views of its future role, as illustrated in the European Parliament and society more generally. The aim of this paper is to investigate the barriers to advancing bioenergy use and prospects for the future of bioenergy in the EU. Whereas previous studies have focused on specific aspects of EU bioenergy, such as market structure, technological considerations, and individual forms of bioenergy, this study provides results from a survey analyzing several factors that are inhibiting overall bioenergy development throughout the EU. The results show that, in general, the growth of bioenergy use in the EU can be expected to continue, although there are many issues that need to be addressed by society and through policy implementation. The most important of these issues include the relationship between the future role of the fossil fuel using industry and bioenergy, addressing the inadequate and currently confusing level of policy support, and responding to the perception of low public acceptance, reflected by pressure from some nongovernmental organizations to reduce the use of bioenergy. The study shows that biomass is not always the best option in economic terms, and other options such as heat pumps powered by green electricity or natural gas can be more financially attractive. To ensure the continuing development of the bioenergy field in the EU, it is important to increase local policy support for bioenergy, decrease imports of fossil fuels from non‐EU countries, increase investment in the bioenergy sector, and engage in effective and fact‐based education about, and promotion of, bioenergy.
