新型农业经营主体的经营绩效与差异分析——基于农村固定观察点的数据调查

新型农业经营主体的经营绩效关系到其可持续发展。采用农村固定观察点对我国各省区新型农业经营主体的调查数据,运用随机前沿分析法,对不同类型的经营主体的经营绩效进行分析,并进一步分析新型农业经营主体的差异性。结果表明：相比小农户而言,新型农业经营主体的经营绩效相对较高,但是其平均绩效还有很大的改善空间;新型农业经营主体面临融资难和人才缺乏的问题,且该问题在农民专业合作社中最为突出;我国家庭农场的经营绩效在三种新型农业经营主体中是最高的,其次是农业（龙头）企业,最后是农民专业合作社。对此,提出应完善土地“三权分置”机制,实现新型农业经营主体的规模化生产,进一步解决其融资难和人才缺乏的问题,加大政策扶持力度等建议。     

Problem‐ and solution‐focused characteristics of parenting support, 3 years after implementation of the solution‐focused approach: A qualitative content analysis

In recent years, solution‐focused parenting support has been developed and implemented as a promising brief and strength‐based approach. Given the fundamental differences between solution‐focused and the historically more common problem‐focused parenting support and the complexity of transforming professional practice, an actual shift towards solution‐focused parenting support can be expected to be limited up to now. However, because research into the specific communication characteristics of professional parenting support is currently lacking, no conclusion can be drawn at present. Therefore, this study aims to explore the current problem‐ and solution‐focused characteristics of parenting support in the Dutch youth healthcare (YH). In total, 15 support sessions performed by 10 public health nurses were audio recorded and transcribed verbatim. A detailed qualitative content analysis of professional communication was conducted to identify problem‐ and solution‐focused factual, expressive, relational and appealing aspects of parenting support. Problem‐focused characteristics dominated all sessions of parenting support. This study is the first to thoroughly analyse the problem‐focused and solution‐focused communication characteristics of professional parenting support using a qualitative content analysis. Parenting support practice in the Dutch YH did not shift substantially to a solution‐focused approach. More effort is required to stimulate and facilitate this professional transformation.     

Early Pregnancy Assessment Services in Australia: What psychosocial support is available? A qualitative study

ProblemWomen commonly experience emotional distress following miscarriage but do not receive the support they need from healthcare providers.BackgroundMiscarriage can result in psychological morbidity; however, appropriate support at the time of a miscarriage can lead to better psychological outcomes. Early Pregnancy Assessment Services (EPASs) are dedicated outpatient services considered the “gold standard” for miscarriage care. Little is known about the psychosocial support EPASs provide in Australia.AimsThe aim of this study was to explore the provision of psychosocial support in Australian EPASs.MethodsSemi-structured interviews were conducted with 29 purposively sampled key-informants from 13 EPASs. Interviews were audio-recorded, transcribed, and thematically analysed.FindingsConsiderable variation was found in how EPASs functioned and their provision of psychosocial support. Many services were co-located with antenatal services, run by doctors with limited experience and most did not offer any psychosocial training to staff specific to EPAS. Referrals for additional support were generally not offered for first trimester miscarriages, and follow-up typically focused on physical management rather than emotional wellbeing. All EPAS staff demonstrated a strong commitment to providing best possible care to women within their own clinical setting and acknowledged the need for improved psychosocial support.ConclusionThis study provides the first exploration of Australian EPASs’ provision of psychosocial support. It has shown that while health care professionals working in EPASs are dedicated to providing the best possible care to women within their clinical setting, psychosocial support is very limited and could be improved.     

‘A Chance to Stand Back’: Parenting Programmes for Parents of Adolescents

Parenting interventions were an important feature of New Labour’s policies to combat social exclusion. This paper critically examines parenting programmes for families with adolescents, assessing national and local policy aims against the perspectives of women who took part in a parenting course, which was the subject of a local evaluation. The paper argues that, while there were important positive outcomes for the participants, the high levels of unmet need which women reported reflect important disparities between the aims of the intervention, the level of service provision, and the needs and concerns of mothers and grandmothers.     

An Ecological Understanding of Caregiver Experiences in Palliative Care

Palliative care is specialized health care to improve quality of life for patients with serious illness and their families through prevention and relief of suffering. A Palliative Care Institute was held in western Washington to capture community voices about diverse needs, strengths, and opportunities for improvement of palliative care. Researchers employed qualitative methods to obtain thematic data, provide real-time analysis, and engage in a multivoting technique to reflect stakeholder interest in individual themes and prioritize larger group interests. Bronfenbrenner’s ecological systems framework was used to explore caregiver experiences. Within the microsystem, caregivers reported difficulties in interactions with medical providers as a key challenge. Within the mesosysytem, interactions between patients and medical providers and the impact on caregivers were explored. Within the exosystem, caregivers reported lack of control over the schedules of personal care staff. Macrosystem influences included impact of local culture on the development of palliative care services. Chronosystem influences include de-medicalization of childbirth and its impact on perceptions of palliative care. Implications include the need for social workers to be proactive in fostering trust and effective communication between care providers and caregivers, and the demand for health care provider training in communication with patients and families.     

中国社会传统家庭伦理父子关系的现代扬弃

中国封建社会伦理之中,积淀了丰富的以＂尊亲＂、＂顺亲＂、＂养亲＂等为主要内容的父子伦理精义;在中国社会结构由金字塔型演变为橄榄型、步入了后喻社会时代的今天,封建社会时代形成的许多父子伦理内容和沟通模式已不适合当今社会时代的发展要求。在今日中国社会伦理系统之中,应该建立新型的父子伦利（互利）关系。这既需要借鉴现代社会的＂互喻＂模式,又要采补传统伦理的精髓内容。

Practical procedures to deal with common support problems in matching estimation

This paper assesses the performance of common estimators adjusting for differences in covariates, such as matching and regression, when faced with the so-called common support problems. It also shows how different procedures suggested in the literature affect the properties of such estimators. Based on an empirical Monte Carlo simulation design, a lack of common support is found to increase the root-mean-squared error of all investigated parametric and semiparametric estimators. Dropping observations that are off support usually improves their performance, although the magnitude of the improvement depends on the particular method used.     

社会资本与身心健康--概念辨析基础上的关系再检验

社会资本与健康研究领域存在核心概念界定不清与理论解释欠缺两大不足。文章在社会网络的视角下对社会资本、社会凝聚和社会支持三个相互杂糅的概念进行辨析区分，并在此基础上以调查数据实证检验了社会资本对身心健康的作用效果与影响机制。结果显示，在控制社会凝聚和社会支持作用的条件下，社会资本依然对自评健康和心理健康存在显著的独立影响，但其对两种健康在影响因素和影响方向上呈现一些差异。其中，网络规模和网络顶端对自评健康和心理健康都具有显著的正向作用，而心理健康同时还受到网络差异的负向影响。从这个角度而言，社会资本对个体身心健康的影响并不必然是积极正向的。     

Conditional and marginal estimates in case-control family data – extensions and sensitivity analyses

This work considers two specific estimation techniques for the family-specific proportional hazards model and for the population-averaged proportional hazards model. So far, these two estimation procedures were presented and studied under the gamma frailty distribution mainly because of its simple interpretation and mathematical tractability. Modifications of both procedures for other frailty distributions, such as the inverse Gaussian, positive stable and a specific case of discrete distribution, are presented. By extensive simulations, it is shown that under the family-specific proportional hazards model, the gamma frailty model appears to be robust to frailty distribution mis-specification in both bias and efficiency loss in the marginal parameters. The population-averaged proportional hazards model, is found to be robust under the gamma frailty model mis-specification only under moderate or weak dependency within cluster members.
