通过对1 154名初一至高三学生的调查,探索累积生态资源、青少年自我效能感与意向性自我调节三者之间的关系。具体来说,青少年拥有的生态资源数量正向预测意向性自我调节水平,而青少年的自我效能感中介作用于生态资源数量与意向性自我调节的关系。这表明,累积生态资源既可直接对青少年意向性自我调节产生积极影响,又可通过自我效能感对意向性自我调节产生间接作用。因此,在推进积极心理健康教育的进程中,需要凸显青少年在自身发展中的自主性以及多重生态资源的联合作用。  相似文献

长期护理需求评估是长期护理保险筹资与给付的联结点,直接决定了保险给付,并对长期护理保险筹资有重要影响.当前我国试点地方在长期护理需求评估制度的设计上分歧较大,虽积累了差异化的经验与案例,但地区分割不利于社会公平与社会流动.应立足于长期护理保险的社会保险属性,结合社会实际与试点效果,适当借鉴德国经验,统筹设计长期护理需求评估体系,通过"法律+行政法规+部门规章"的规范形式,精准定位评估对象,明确独立的评估主体、科学设计评估指标与评估工具、严格规范评估程序等确保评估结果的科学、客观与公正,并根据评估结果进行分级分类给付,实现长期护理保险资源流向精准.  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

《民法典》技术合同章体现了商事化变革的趋势,技术合同制度的商事化变革经过三个阶段的发展历程,其推动力量主要来自制度和现实两个层面。知识产权法对技术合同章商事化变革具有促进作用,并对其独立性产生影响。在商事化变革中,技术合同章的管制主义倾向弱化,应当将技术合同定位为关系合同,并对技术合同条款从商事角度进行解释,为在技术合同章具体制度规则中体现商事化变革的要求,有必要均衡适用知识产权保护原则性条款,限制技术合同无效的情形,对技术成果共有规则从商事角度加以适用,并重视技术成果优先受让权规则的作用。  相似文献

BackgroundHaving a positive childbirth experience is an increasingly valued outcome. Few studies evaluated the women’s satisfaction with childbirth through face-to-face interviews out of the health service environment. The objective of this study was to identify factors associated with a higher level of satisfaction with the childbirth experience among Brazilian women.MethodsThis cross-sectional study involved 287 women giving birth in two hospitals in southern Brazil. Women who gave birth to healthy newborns at term were randomly selected. Face-to-face interviews were conducted 31–37 days after delivery, at the mothers’ homes, using a structured questionnaire. Satisfaction with the childbirth experience was measured using a Likert-type scale ranging from very satisfied to very dissatisfied. Prevalence ratios (PR) were estimated using Poisson regression with robust variance.ResultsFollowing hierarchical multivariate analysis, the following factors remained associated with a higher level of satisfaction with the childbirth experience: being satisfied with antenatal care (PR = 1.30; 95% confidence interval [95%CI] = 1.06−1.59), understanding the information provided by health professionals during labor and delivery (PR = 1.40; 95%CI = 1.01−1.95), not having reported disrespect and abuse (PR = 1.53; 95%CI = 1.01−2.31), and having had the baby put to the breast within the first hour of life (PR = 1.63; 95%CI = 1.26−2.11). No association was observed with type of delivery or hospital status (public or private).ConclusionsA higher level of satisfaction with the childbirth experience is related to satisfactory antenatal care, a non-abusive, respectful, and informative environment during childbirth, and to the opportunity to breastfeed the baby within the first hour of life. In clinical practice, greater attention to these basic principles of care during pregnancy and delivery could provide more positive experiences during birth.  相似文献

Although the party‐state has embarked on a mission to increase elder care services, evaluating this development according to different sectors demonstrates certain challenges. Official statistics do not include sector‐specific information, and while provider websites suggest that elder care services are largely in public hands, Chinese experts argue that they are mostly “civilian‐run.” How can we explain these discrepancies in data on Chinese elder care? Drawing on the concept of hybridization and triangulating quantitative and qualitative data, I argue that the party‐state's efforts to “socialize” elder care provision has resulted in hybridization within the industry which blurs the line between care providers and obfuscates the stark role of the state in elder care service provision. During the implementation of state‐initiated hybridization, providers misclassify their ownership type to benefit from financial incentives or circumvent political control, resulting in even greater hybridization and fragmentation on the ground.  相似文献

BackgroundMidwife-led continuity of care has substantial benefits for women and infants and positive outcomes for midwives, yet access to these models remains limited. Caseload midwifery is associated with professional satisfaction and lower burnout, but also impacts on work-life boundaries. Few studies have explored caseload midwifery from the perspective of midwives working in caseload models compared to those in standard care models, understanding this is critical to sustainability and upscaling.AimTo compare views of caseload midwifery – those working in caseload models and those in standard care models in hospitals with and without caseload.MethodsA national cross-sectional survey of midwives working in Australian public hospitals providing birthing services.FindingsResponses were received from 542/3850 (14%) midwives from 111 hospitals – 20% worked in caseload, 39% worked in hospitals with caseload but did not work in the model, and 41% worked in hospitals without caseload. Regardless of exposure, midwives expressed support for caseload models, and for increased access to all women regardless of risk. Fifty percent of midwives not working in caseload expressed willingness to work in the model in the future. Flexibility, autonomy and building relationships were positive influencing factors, with on-call work the most common reason midwives did not want to work in caseload.ConclusionsThere was widespread support for and willingness to work in caseload. The findings suggest that the workforce could support increasing access to caseload models at existing and new caseload sites. Exposure to the model provides insight into understanding how the model works, which can positively or negatively influence midwives’ views.  相似文献

BackgroundSupporting women to continue breastfeeding is a global challenge. The Milky Way Program is an effective face to face intervention to increase breastfeeding rates up to six months postpartum. The sustainability and access to the Milky Way Program could be enhanced by transforming it into a mobile application allowing women to access relevant information from their own place at a convenient time.AimTo explore the process of transforming the Milky Way Program into an acceptable and usable mobile health application.MethodStakeholders including multidisciplinary researchers and end-users designed the application based on the Milky Way Program by using Persuasive System Design principles. A mixed-method approach was used in the development and evaluation process. Seven women were recruited through convenience sampling to pilot test the application. The women’s feedback was collected through an online survey six weeks after birth and individual interviews at four months postpartum.FindingsWomen in the pilot study reported that the breastfeeding application was well designed, easy to use, interactive, reassuring and evidence-based with credible sources of information.ConclusionThe Persuasive System Design model combined with end-user engagement can feasibly inform the development of an acceptable and usable mobile health application for breastfeeding based on a proven clinical intervention. Further rigorous testing is required to evaluate the effectiveness of the application on breastfeeding initiation and duration.  相似文献

BackgroundPre-registration midwifery students in Australia undertake a minimum of ten continuity of care experiences with childbearing women. However, women are rarely asked to formally evaluate this care by students.AimTo evaluate data from a routine, web-based survey of women about having a midwifery student provide a continuity of care experience.MethodsAll women (n = 886) recruited by a midwifery student for a continuity of care experience during a 12 month period received an email inviting them to complete an online survey. The survey included personal details, experiences of care, and two scales on Respect and Satisfaction.ResultsA response rate of 57% (n = 501) was achieved. On average students attended six antenatal visits (mean = 5.83) and had six postnatal contacts with women. Most students attended labour and birth (92.6% n = 464). Most women rated overall satisfaction with care by their student as ‘better than they had hoped’. Positive correlations were found between number of antenatal visits and postnatal contact with students on both levels of satisfaction and respect felt by women. Women felt more satisfied when their midwifery student attended labour and birth.ConclusionsThe online survey was feasible and provided valid and reliable feedback from women about their student during a continuity of care experience. Women valued having an ongoing relationship with a student during pregnancy, labour and birth, and postpartum. Pre-registration midwifery education programs should continue to privilege relationship-based care and national standards should support the effective integration of continuity of care experiences.  相似文献
