To gain an in-depth understanding of China’s urban labor market,the Institute of Population and Labor Economics at the Chinese Academy of Social Sciences(IPLE-CASS)conducted the fifth wave of the China Urban Labor Survey in 2023,which covers eight major representative cities.The survey collected 9,122 household questionnaires and 26,145 individual questionnaires from 381 neighborhood committees.Based on this data,the report systematically analyzes employment,wages,educational attainment,and social security among China’s urban workforce.Key findings include an inverted U-shaped age pattern of labor force participation,with a widening gender gap after childbearing age.Additionally,job search methods combine market-based channels with traditional social networks.Notably,the gender wage gap persists and widens over the life cycle,while employed women now have higher average years of schooling than men.Rural-to-urban migrants show higher labor force participation rates but remain disadvantaged in wages,education,and social security coverage.Thus,this survey provides a comprehensive picture of the structural characteristics and challenges of China’s urban labor market,providing a solid data foundation for academic research and public policy design. 展开更多

BACKGROUND Gastrointestinal endoscopy technology has significantly improved the diagnostic accuracy and the successful treatment of gastrointestinal diseases.However,a series of ethical issues have emerged,such as expanding treatment indications,which affect the fair distribution of medical resources.There is limited research on ethical issues in the field of digestive endoscopy.AIM To investigate the level of ethical awareness among gastrointestinal endoscopy practitioners and analyze the ethical issues involved in gastrointestinal endoscopy technology.METHODS A questionnaire survey was performed to collect relevant data(gender,age,degree of education,professional title,personnel category,the level of understanding medical ethical principles,ethics training and its learning pathways)from gastrointestinal endoscopy practitioners at the Second Hospital of Dalian Medical University and Dalian Friendship Hospital,including licensed physicians and nurses(including trainees and graduate students).RESULTS The majority of gastrointestinal endoscopy practitioners have received training on ethics,but there is still considerable room for improvement in their ethical awareness.Different learning pathways may affect the mastery of ethical principles, and understanding of ethical principles is more easily achieved through hospital ethics institutions.CONCLUSIONTo address the ethical issues in gastrointestinal endoscopy technology, it is necessary to enhance the humanisticeducation of gastrointestinal endoscopy practitioners, incorporate ethical standards into the technology assessmentprocess, and establish a patient-centered diagnostic and treatment model to improve the ethical awareness of practitionersand achieve a balance between technology and ethics. 展开更多

AIM:To assess risk factors for epiretinal membranes(ERM)and examine their interactions in a nationally representative U.S.dataset.METHODS:Data from the 2005–2008 National Health and Nutrition Examination Survey(NHANES)were analyzed,a nationally representative U.S.dataset.ERM was identified via retinal imaging based on the presence of cellophane changes.Key predictors included age group,eye surgery history,and refractive error,with additional demographic and health-related covariates.Weighted univariate and multiple logistic regression models were used to assess associations and interaction effects between eye surgery and refractive error.RESULTS:Totally 3925 participants were analyzed.Older age,eye surgery,and refractive errors were significantly associated with ERM.Compared to those under 65y,the odds ratio(OR)for ERM was 3.08 for ages 65–75y(P=0.0014)and 4.76 for ages 75+years(P=0.0069).Eye surgery increased ERM risk(OR=3.48,P=0.0018).Moderate to high hyperopia and myopia were also associated with ERM(OR=2.65 and 1.80,respectively).A significant interaction between refractive error and eye surgery was observed(P<0.0001).Moderate to high myopia was associated with ERM only in those without eye surgery(OR=1.92,P=0.0443).Eye surgery was most strongly associated with ERM in the emmetropic group(OR=3.60,P=0.0027),followed by the moderate to high myopia group(OR=3.01,P=0.0031).CONCLUSION:ERM is significantly associated with aging,eye surgery,and refractive errors.The interaction between eye surgery and refractive error modifies ERM risk and highlights the importance of considering combined effects in clinical risk assessments.These findings may help guide individualized ERM risk assessment that may inform personalized approaches to ERM prevention and management. 展开更多

BACKGROUND Understanding a patient's clinical status and setting priorities for their care are two aspects of the constantly changing process of clinical decision-making.One analytical technique that can be helpful in uncertain situations is clinical judgment.Clinicians must deal with contradictory information,lack of time to make decisions,and long-term factors when emergencies occur.AIM To examine the ethical issues healthcare professionals faced during the coronavirus disease 2019(COVID-19)pandemic and the factors affecting clinical decision-making.METHODS This pilot study,which means it was a preliminary investigation to gather information and test the feasibility of a larger investigation was conducted over 6 months and we invited responses from clinicians worldwide who managed patients with COVID-19.The survey focused on topics related to their professional roles and personal relationships.We examined five core areas influencing critical care decision-making:Patients'personal factors,family-related factors,informed consent,communication and media,and hospital administrative policies on clinical decision-making.The collected data were analyzed using the χ^(2) test for categorical variables.RESULTS A total of 102 clinicians from 23 specialties and 17 countries responded to the survey.Age was a significant factor in treatment planning(n=88)and ventilator access(n=78).Sex had no bearing on how decisions were made.Most doctors reported maintaining patient confidentiality regarding privacy and informed consent.Approximately 50%of clinicians reported a moderate influence of clinical work,with many citing it as one of the most important factors affecting their health and relationships.Clinicians from developing countries had a significantly higher score for considering a patient's financial status when creating a treatment plan than their counterparts from developed countries.Regarding personal experiences,some respondents noted that treatment plans and preferences changed from wave to wave,and that there was a rapid turnover of studies and evidence.Hospital and government policies also played a role in critical decision-making.Rather than assessing the appropriateness of treatment,some doctors observed that hospital policies regarding medications were driven by patient demand.CONCLUSION Factors other than medical considerations frequently affect management choices.The disparity in treatment choices,became more apparent during the pandemic.We highlight the difficulties and contradictions between moral standards and the realities physicians encountered during this medical emergency.False information,large patient populations,and limited resources caused problems for clinicians.These factors impacted decision-making,which,in turn,affected patient care and healthcare staff well-being. 展开更多

BACKGROUND Artificial intelligence(AI)is increasingly being explored in radiology,including its potential role in emergency imaging settings.However,global perspectives on AI adoption,usefulness,and limitations among emergency radiologists remain underexplored.AIM To assess awareness,usage,perceived benefits,and limitations of AI tools among radiologists practicing emergency radiology worldwide.METHODS A 16-question survey was distributed globally between October 24,2024,and August 4,2025,targeting radiologists working in academic,community,and private settings who practice emergency radiology as a primary or secondary subspecialty.The survey was disseminated via direct emails extracted using automated and manual methods from recent publications in major radiology journals.A total of 57 responses were collected.RESULTS AI awareness was high(93%),but frequent clinical use was reported by only 28%.Daily use of AI in emergent imaging was limited to 23%of respondents.The majority anticipated AI becoming essential within five years(68%),and 51%believed AI would replace certain radiological tasks.Image interpretation and acquisition were the most common AI applications.Key perceived benefits included improved diagnostic accuracy and increased efficiency,while concerns included limited accuracy,integration difficulties,and cost.Trust in AI varied by experience,with less experienced radiologists viewed as more trusting.CONCLUSION While emergency radiologists globally recognize AI’s potential,significant barriers to its routine adoption remain.Addressing issues of trust,cost,accuracy,and workflow integration is essential to unlock AI's full utility in emergency radiology. 展开更多

Since its introduction as a decentralized digital currency for peer-to-peer transactions,Bitcoin’s role in financial markets has undergone significant evolution.We employ bibliometric analysis to explore research trends in Bitcoin,identifying two primary perspectives in the recent financial economic literature:Bitcoin as a speculative asset and as a safe-haven asset.The speculative nature of Bitcoin is evident through its high volatility and frequent price jumps,largely influenced by rapid shifts in investor sentiment and attention,which create both risks and opportunities for traders.Conversely,Bitcoin exhibits characteristics of a safe-haven asset due to its asymmetric tail dependence and negative correlation within certain asset classes. 展开更多

The Stellar Abundances and Galactic Evolution Survey(SAGES)is a multi-band survey that covers the northern sky area of~12,000 deg2.The Nanshan One-meter Wide-field Telescope(NOWT)of the Xinjiang Astronomical Observatory carried out observations on g/r/i bands.Here,we present the survey strategy,data processing,catalog construction,and database schema.The observations of NOWT started in 2016 August and were completed in2018 January,a total of 17,827 frames were obtained and~4600 deg2 sky areas were covered.In this paper,we release the catalog of the data in the g/r/i bands observed by NOWT.In total,there are 109,197,578 items of source records.The catalog is the supplement for the SDSS for the bright end,and the combination of our catalog and these catalogs could be helpful for source selections for other surveys and Milky Way sciences,e.g.,white dwarf candidates and stellar flares. 展开更多

Pharmacy clinics,staffed by clinical pharmacists who interact directly with patients,encompass services such as medication reconciliation,education,follow-up visits,and lifestyle guidance.Their primary goal is to enhance patients’quality of life.Numerous studies,both domestic and international,have highlighted the benefits of pharmacy clinics in optimizing drug therapy quality and reducing treatment costs,particularly for long-term medication management in organ transplant recipients and similar patient groups.Despite these benefits,pharmacy clinics are still in the early stages of development in China.There remains a lack of clarity regarding the specific development and service content of pharmacy clinics tailored for transplant patients.Therefore,this study aimed to assess the current status of pharmacy clinic development for transplant patients in China and provide insights to hospitals for advancing and strengthening transplant pharmacy clinic initiatives. 展开更多

[Objective]Mental health is the essence of physical health,human beings pay more and more attention to the study of mental health recovery and after many studies,it is clear that the restorative environment has an important and positive significance for their mental recovery,and species as an important part of the environment since the natural environment has been used as an essential part of the research environment,based on the conditions of such a social reality,this paper analyzed the articles on species surveys in the last 30 years,used the data to reflect the importance of species survey,and the research hotspot of restorative environment.[Methods]The study analyzed the data in articles about species survey in CNKI database from 1994 to 2024 through Citespace visualization,and analyzed the data through the number of articles issued between years,keyword co-occurrence and other aspects,so as to give data support for the research of restorative environment.[Results]In the past 30 years,the number of articles published on species survey has increased year by year,and species survey is at the forefront of research hotspots.Clustering and timeline analysis results of insects,birds,diversity has become more important.[Conclusions]From the 621 articles,the following aspects could be concluded:(1)The importance of restorative environments research and the vast exchanges among scholars have been reflected and more research hotspots have been explored in this field;(2)For the research direction of restorative environments and this paper,the research hotspots were in line with the in-depth exploration of species diversity,which was not only in the field of species,but also in the field of health and the environment,and there were also investigations of the links;(3)The interdependence between species diversity and restorative environments was high,further research on restorative environments largely depended on the study of species surveys. 展开更多

Confirming tornado occurrence and estimating tornado intensity are quite challenging,especially for long-track tornadoes and tornado outbreaks,because of the inefficiency or absence of on-site damage surveys,especially in sparsely populated regions,which brings about large uncertainties in the tornado record.Some potential methods to alleviate this uncertainty in tornado records have been introduced,such as reports from tornado enthusiasts,trawling of social media sites,and spaceborne photography,which have been shown to be efficient in collecting damage information and depicting the damage swath and ascertaining tornado records.Unmanned aerial vehicles may help in effectively rating tornado intensities.Since 2021,some of these methods have been being tested or are under operation at the China Meteorological Administration Tornado Key Laboratory and the Foshan Tornado Research Center,and have proved to be effective.They have great potential in advancing tornado or downburst damage surveys nationally or worldwide,as well as assessing tornado climatologies,especially in sparsely populated regions such as Northeast China. 展开更多
