自然保护地在维持生态平衡,实现生态系统服务功能中可以发挥重要作用,但不同类型自然保护地的主导生态系统服务功能供给存在一定差异.《自然保护地法》立法工作须依赖理论上对自然保护地的类型化,并在此基础上建构对应型的规划建设、运营管理等方面的具体制度.因此,基于生态系统服务功能供给的空间差异,可以将当前相互重叠、缺乏体系的自然保护地划分为国家公园、自然保护区、自然公园、自然保护小区等四种类型,搭建"1部基础法律+4部类型化条例(或法律)"的自然保护地法律体系,并可以通过体系化公法、私法制度工具强化自然保护地的有效治理. 相似文献

基于CHARLS 2015数据,采用倾向得分匹配法实证分析参加医疗保险对农村居民健康的影响。研究发现:参加医疗保险对农村居民的日常活动能力和自评健康影响不显著,参加医疗保险对农村居民认知能力具有显著的正向影响。据此提出,应进一步提升社会医疗保险保障水平、扩大社会医疗保险保障范围、促进商业医疗保险有序发展、推进"三医"高效协同联动等,以充分发挥医疗保险的健康保障功能,从而进一步提升参加医疗保险对农村居民健康的正向影响。 相似文献

Recent guidance on safety monitoring during drug development, issued by regulatory authorities in the United States and European Union, indicate a shift in focus towards aggregate safety monitoring and scientific evaluation of integrated safety data. The call for program‐level reviews of accumulating safety data, including from ongoing studies, provides an opportunity to leverage the scientific expertise and medical judgment of safety management teams with (a) a multidisciplinary approach, (b) quantitative frameworks to measure level of evidence, and (c) assessments that are product‐specific and driven by medical judgment. A multidisciplinary team, regularly reviewing aggregate safety data throughout the development program, is vital not only for early signal detection but also for generating a better understanding of the accumulating data and context needed for decreasing false alarms. 相似文献

The anatomy lab has been studied by sociologists interested in professional socialization since the 1950s. This is because the act of dissecting a cadaver is thought to be foundational for both the student's medical knowledge and the development of the student's professional identity. In this paper, I revisit the anatomy lab both historically and ethnographically. Drawing on theoretical insights from the laboratory ethnography tradition within science and technology studies, I show that students use material artifacts in the lab to support their “surgical identity play.” This activity is structured by the laboratory's performative architecture even while it is unsupervised by anatomy faculty. While many analyses of professional socialization focus on how students learn to interact with patients during their training, I show that the anatomy lab experience is an important form of professional socialization because here students learn to employ surgical instruments, language, and dress, and begin to relate to each other as colleagues. 相似文献

ABSTRACT Employee financial wellness programs (EFWPs) are a new practice that may promote financial inclusion by making it easier for workers with low- and moderate-incomes (LMI) to access financial services. We examine the strengths and limitations of workplace financial counseling, credit-building services, and small-dollar loans, and describe community collaboration to promote employee financial wellness. Findings suggest that these services are reaching a population that experiences financial exclusion, though evidence is mixed concerning how these services help workers with LMI resolve key financial challenges. Community collaboration focused on employee financial wellness presents opportunities to advocate for higher wages and better benefits. 相似文献

Despite widespread availability of yoga in the Veterans Health Administration (VA), it remains unclear how to best evaluate yoga programs. This is particularly problematic for programs aimed at veterans with mental health concerns, as evaluation typically focuses narrowly upon mental health symptom severity, even though program participants may have other health-related priorities. We analyzed responses to free-text questions on 237 surveys completed by veterans with mental health concerns enrolled in a yoga program at six VA clinics in Louisiana to characterize veteran participants’ experiences with yoga. Qualitative analysis resulted in 15 domains reflecting veterans’ individual health-related values and priorities. We use results to illustrate the potential for analysis of free-text responses to reveal valuable insights into patient experiences, demonstrating how these data can inform patient-centered program evaluation. The approach we present is more accessible to those responsible for decision-making about local programs than conventional methods of analyzing qualitive evaluation data. 相似文献

AbstractObjective: We aimed to explore knowledge, attitudes, and beliefs about vaccines required for college-entry and vaccine-related behaviors among college students. Participants: Thirty-three full-time undergraduate students, ≥ 18 years old, enrolled at public (2) and private (3) colleges and universities in metropolitan Philadelphia in fall 2016. Methods: We conducted semistructured interviews, which were double-coded with 5,015 comments overall and 99.3% intercoder reliability (κ?=?0.779) using NVivo 11 software. Results: Six key themes emerged: (1) low knowledge about vaccines and requirements; (2) mixed attitudes about required vs. recommended vaccines; (3) high trust in medical professionals; (4) low perceived risk for vaccine-preventable disease outbreaks; (5) substantial parental influence on students’ decision-making; and (6) low utilization of Student Health Services. Conclusions: This study revealed lack of knowledge about and low prioritization of vaccination despite overall positive attitudes towards vaccines. Prematriculation education of college students is critical to increasing vaccine knowledge and use. 相似文献

Abstract Many campuses are seeing increased needs for support in scholarly communications areas such as open access, research identity management, scholarship metrics, and related topics. This article discusses a professional development program that addresses scholarly communications needs for online and in-person graduate students and faculty at UNC Greensboro (UNCG), through a collaborative, interdepartmental effort that brings together librarians from the departments of Research, Outreach, and Instruction (ROI) and Technical Services. The authors provide a brief overview of the literature related to scholarly communications needs and training in academic libraries and discuss the UNCG program’s inception, modules, format, assessment, and future directions. 相似文献

AimTo assess the antenatal care utilisation among Syrian refugees in Tehran.MethodsThis cross-sectional study was performed in 2016 in Tehran. As the refugees live in the city, we used Respondent Driven Sampling method for finding participants. Data were collected from interviews by a newly graduated Syrian general practitioner.FindingsIn total, 231 women participated in the study. The mean (standard deviation) number of antenatal care visits was 3.73 (1.41) and 131(56.7%) women received at least four visits. The mean (standard deviation) number of antenatal care visits was higher among women with four or more living children compared with those with four or more: 3.47 (1.35); 95% confidence interval 3.28 to 3.66 vs. 2.82 (1.64); 95% confidence interval 2.25 to 3.40, p = 0.01. The mean (standard deviation) number of antenatal care visits was higher among women whose spouses had academic degrees compared with those with lower education: 4.13 (1.37); 95% confidence interval 3.86–4.40 vs. 3.28 (1.31); 95% confidence interval 3.05–3.52, p < 0.001.ConclusionsAntenatal care utilisation of Syrian women in Tehran complied with neither national guidelines of Iran nor the recommendations of World Health Organization. However, antenatal care utilisation of Syrian women in Tehran was higher than the main destinations of Syrian refugees. Syrian women kept their own cultural behaviour in terms of antenatal care utilisation. 相似文献
