Social governance innovation is a basic requirement of China's socialist construction, and an important guarantee that people can live and work in peace and enjoy long-term stability and order. Strengthening and innovating social governance has great significance for the modernization of the national governance system and governance capacity, and this is where judicial justice plays a unique role at the level of government, society, and the individual. That is, judicial justice is the key to transforming governmental functions; the guarantee of a new-type social construction; and the guide to upgrading autonomy at the grass-roots level. To achieve judicial justice, we must popularize the idea of the rule of law, improve judicial work style and innovate judicial institutions.  相似文献

在超竞争环境下企业面临的竞争环境越来越动荡,企业的竞争优势呈现出短期性与临时性的特点,为了快速发展,越来越多的企业选择并购。本文以超竞争环境为研究背景,运用期权博弈理论,分析并建立了存在竞争对手的企业困境并购定价与时机选择模型,通过模型求解得到并购中主并企业给予目标企业的最优价值以及主并企业的最佳并购时机;此外,通过数值模拟重点分析了三个超竞争特征因子(竞争强度、竞争不确定性、企业价值损失因子)、企业困境因子以及竞争对手的溢价水平对企业困境并购时机的影响。本文研究发现:(1)被并企业得到的价值补偿比例及主并企业最佳并购时机均受到各超竞争特征因子、企业困境因子以及竞争对手溢价水平的综合影响;(2)竞争对手的存在会使目标企业得到的价值补偿比例增加;(3)超竞争环境下企业困境并购中主并企业的最佳并购时机取决于并购双方的相对价值比;(4)随着可能导致双方谈判破裂因素、事件的增多以及企业财务困境程度的增加,主并企业提前进行并购的可能性增加;(5)随着竞争强度、竞争不确定性、竞争对手造成溢价水平的增加,主并企业推迟并购时机的可能性增大。  相似文献

A central issue for family therapy is the critical question of how to define its role in influencing social change. Family therapy has tended to focus on how to liberate and empower individual clients, not communities, from the travails of tradition. This article highlights social change mechanisms implemented by the oppressed majority in South Africa during the apartheid period. It draws inspiration from the pedagogy of the oppressed articulated by Steve Biko and other members of his generation. This enabled the Black majority in South Africa ‘to name their world by reflecting on their conditions, imagining a better world, and then taking action to create it’ (Freire, 1968, p. 253) through the use of revolutionary songs that resulted in the collapse of the cruel apartheid system. The implications for family therapy are discussed.  相似文献

药品安全关乎人民群众生命健康、经济发展、社会稳定和国家安全,一直以来都是政府和全社会关注的热点问题之一。但是,近年来频发的各类药品安全事件,揭露了政府监管缺失、药品检测机制不完善、公众投诉失效等诸多问题。本文考虑了药品检测中存在寻租现象,构建了药品生产企业、第三方药品检测机构和政府监管部门之间的三方演化博弈模型,分析了各参与方策略选择的演化稳定性,探讨了各要素对三方策略选择的影响关系,进一步分析了三方博弈系统中均衡点的稳定性。研究结果表明:1)政府增强奖励、惩罚力度均有助于促进企业生产高药效药品、第三方药品检测机构拒绝寻租的规范行为,但是增大奖励力度将不利于政府自身履行监管职责;2)政府设定合理的奖惩机制必须符合对各方的奖惩之和大于其投机收益的条件,才能保障演化稳定市场环境下的药品安全;3)上级政府对监管部门失职的问责对增强企业生产高药效药品的稳健性具有重要意义;4)提升企业的药品销售收益、增加企业寻租成本也是避免企业生产低药效药品的有效途径。最后,利用Matlab 2020b进行了仿真分析,为政府完善药品监管机制提出了对策与建议。  相似文献

BackgroundContinuity models of care are rare in Sweden, despite the evidence of their benefit to women and babies. Previous studies have shown certain factors are associated with a positive birth experience, including continuity of midwifery care.AimThe aim was to investigate women's childbirth experiences in relation to background data, birth outcome and continuity with a known midwife, in a rural area of Sweden.MethodsAn experimental cohort study. Participating women were offered continuity of midwifery care in pregnancy and birth, during selected time periods. Data were collected in mid-pregnancy and two months after birth. The Childbirth Experience Questionnaire was used to determine women's birth experiences.ResultA total of 226 women responded to the follow-up questionnaire. Not living with a partner, fear of giving birth, and a birth preference other than vaginal were associated with a less positive birth experience. Having had a vaginal birth with no epidural, no augmentation and no birth complication all yield a better birth experience. Women who had had a known midwife were more likely to have had a positive birth experience overall, predominantly in the domain Professional support.ConclusionsThe results of this study showed that women who received care from a known midwife in labour were more likely to have a positive birth experience. The results also pointed out the benefits of a less medicalized birth as important for a good birth experience, and that some women may need extra support to avoid a less positive birth experience.  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
