农地产权结构变迁视域下土地增值收益的公平分享

农地产权结构是搭建土地增值收益分配与宪法秩序有效链接的重要桥梁.从农地产权结构变迁的视角看,我国传统土地增值收益的国有化机制实际在很大程度上符合1982年宪法所确立的社会主义地租国有原则及地利共享秩序.然而,由于宪法土地条款一开始就被注入了地利分配具有倾向性的思想基因,长此以往便忽视了农民作为整体分享土地增值收益的"另一半宪法秩序".新型城镇化背景下,国家进行了"同地同权"、赋权于"民"的农村土地管理制度改革,其实质是宪法秩序的延续而非替代,我国土地增值收益分配的主要机制仍是征地补偿制度.要实现我国土地增值收益的公平分享,必须回到社会主义"国家—集体"一元论的完整地利共享秩序中来,并遵循实质平等的要求,通过以"人的城镇化"为目标对区片综合地价进行限定、采取倾向于农村及农业发展的"土地财政"政策、打破城乡户籍二元制实现城乡一体化发展等方案,推动农民全过程参与、共享土地利益.     

How do policy levers shape the quality of a national health system?

Poor quality of care may have a detrimental effect on access and take-up and can become a serious barrier to the universality of health services. This consideration is of particular interest in view of the fact that health systems in many countries must address a growing public-sector deficit and respond to increasing pressures due to COVID-19 and aging population, among other factors. In line with a rapidly emerging literature, we focus on patient satisfaction as a proxy for quality of health care. Drawing on rich longitudinal and cross-sectional data for Spain and multilevel estimation techniques, we show that in addition to individual level differences, policy levers (such as public health spending and the patient-doctor ratio, in particular) exert a considerable influence on the quality of a health care system. Our results suggest that policymakers seeking to enhance the quality of care should be cautious when compromising the level of health resources, and in particular, health personnel, as a response to economic downturns in a sector that traditionally had insufficient human resources in many countries, which have become even more evident in the light of the current health crisis. Additionally, we provide evidence that the increasing reliance on the private health sector may be indicative of inefficiencies in the public system and/or the existence of features of private insurance which are deemed important by patients.     

Midwives’ views of caseload midwifery – comparing the caseload and non-caseload midwives’ opinions. A cross-sectional survey of Australian midwives.

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.     

Challenges of operationalizing trauma‐informed practice in child protection services in New Zealand

New Zealand is undergoing major change in service delivery to children and families. A new Ministry for Children Oranga Tamariki has been established to oversee 5 work streams, one of which provides intensive intervention with families requiring a statutory response to child protection concerns. The government minister responsible promised that the service would be child‐centred and trauma‐informed. To date, these terms remain undefined, and there is no shared understanding of their meaning. Practice frameworks to support the work of the new ministry are still being developed, creating something of a vacuum in the meantime. The focus of this paper is the challenge of implementing trauma‐informed practice in the child protection service provided by the Intensive Intervention work stream. Limited research or commentary on trauma‐informed practice in this context currently exists. Drawing on the relevant available literature, the concept and its application in child protection social work is explored. An ecological framework is used to discuss the changes needed to achieve this. Particular attention is paid to the impact of historical trauma for indigenous people due to New Zealand's colonial history and their over‐representation in care and protection services.     

地区收入、食品价格与恩格尔系数

本文以2016年我国31个省级地区截面数据为样本，构建扩展模型考察恩格尔系数与收入、食品价格之间的关系。研究发现，恩格尔系数与地区收入存在显著的负相关性，纳入食品价格后收入对恩格尔系数的影响变得更为显著，二者关系满足恩格尔定律。恩格尔系数和以地区食品价格平价代表的食品价格之间显著正相关，若再考虑其他因素，则食品价格对恩格尔系数的影响会稍有减弱。进一步将食品区分为生活必需型食品与非生活必需型食品，测算得到的基本恩格尔系数、高阶恩格尔系数与收入之间仍呈负相关关系，但与基本恩格尔系数相比，高阶恩格尔系数与收入之间的负相关性更弱。恩格尔系数受生活必需型食品价格的影响强于非生活必需型食品价格的影响，基本恩格尔系数主要受生活必需型食品价格的影响，而高阶恩格尔系数同时受到两类食品价格的影响。

The Gender Gap in Orgasms: Survey Data from a Mid-Sized Canadian City

Objective: Previous research has established a gap in orgasm frequency between men and women. This study investigates explanations for the gender gap in orgasm. Methods: Crosstab analysis and logistic regression are used to examine the gender gap in orgasms from one Canadian city: Hamilton, Ontario (N = 194). Results: We find a strong association between women’s orgasms and the type of sexual behavior in which partners engage. Women who receive oral sex are more likely to reach orgasm. Conclusion: Sexual practices focused on clitoral stimulation are important to reducing the gender gap in orgasms.     

Diagnostics of multiple group influential observations for logistic regression models

In this paper, two new multiple influential observation detection methods, GCD.GSPR and mCD*, are introduced for logistic regression. The proposed diagnostic measures are compared with the generalized difference in fits (GDFFITS) and the generalized squared difference in beta (GSDFBETA), which are multiple influential diagnostics. The simulation study is conducted with one, two and five independent variable logistic regression models. The performance of the diagnostic measures is examined for a single contaminated independent variable for each model and in the case where all the independent variables are contaminated with certain contamination rates and intensity. In addition, the performance of the diagnostic measures is compared in terms of the correct identification rate and swamping rate via a frequently referred to data set in the literature.     

我国中小学校园欺凌问题研究及薄弱环节——基于CNKI文献关键词的共词分析

随着一系列恶性事件被媒体曝光，社会各界普遍关注和担忧校园欺凌问题，如何解决这一问题，已成为社会焦点。通过共词分析法对我国中小学校园欺凌问题研究现状进行考察发现，其研究主题主要包括六大类：校园欺凌行为特征研究、校园欺凌与学校管理的关系研究、校园欺凌与人际交往的关系研究、校园欺凌的成因与对策研究、校园欺凌的预防与治理研究、校园欺凌的社会问题研究，而研究的薄弱环节则主要包括品格教育研究、学生自我保护研究以及网络欺凌问题研究。因此，校园欺凌问题研究亟待进一步深化，研究视角也需进一步拓展。首先，除欺凌者、被欺凌者之外，旁观者也应纳入研究范畴，要将欺凌者和被欺凌者实施隔离，对受欺凌者要及时给予心理疏导，引导旁观者积极主动地帮助被欺凌者；其次，建议尽快出台相关的法律法规，为学校、教师及相关部门有效处理、解决校园欺凌问题提供法律支持及保障；最后，将综合预防与治理相结合，建立由学校、教师、学生组成的反欺凌共同体。
