亲子分离对留守儿童的影响——基于亲子分离具体化的实证研究

针对既有留守儿童研究把留守儿童作为一个整体,忽视留守儿童内部可能存在的差异性特征,本研究从分离的形式、时间、空间、时机等多个维度来还原具体的亲子分离模式,并藉此考察不同模式的亲子分离在劳动负担、自闭倾向、厌学情绪、学习成绩和主观幸福感五个方面对留守儿童造成的影响。结果发现,在上述五个方面,不同模式的亲子分离对留守儿童所产生的影响呈现出差异。特别是,这种影响具有显著的性别效应,与母亲分离显著影响儿童的自闭倾向、幸福感等主观方面,与父亲分离对儿童的学业表现具有一定的影响。这些论点深化了目前有关留守儿童问题的研究,对农民工的家庭决策具有重要的参考价值。     

The Voice of the Child in Parenting Coordination: Views of Children,Parents, and Parenting Coordinators

This article examines the views of children, parents, and parenting coordinators (PCs) on child inclusion in the parenting coordination process. Participants in a parenting coordination pilot project in Montréal, Quebec—10 children (ranging in age from 8–17 years old), 14 parents, and 2 PCs—were interviewed at the end of the project. The goal was to understand their perceptions of child participation in parenting coordination interventions. Overall, a vast majority of children and parents agreed that children should be given a forum in parenting coordination and their voices heard. Feedback from PCs on their child inclusion experience also provided rare insight into this practice. Results confirm the importance for children of being heard in postseparation interventions, even when parental conflict is high. These findings add to the growing literature on the participation of children in postseparation interventions.     

A Therapist’s Mandate?: Integrating an Ethics of Care into Custody Law by Recognising and Responding to Post‐separation Parental Loss of Connection with Children

In 1999 Smart and Neale published their seminal book Family Fragments, arguing for the replacement of the ethics of justice that currently informs custody law and practice with an ethics of care. Recognising loss is one of four principles they identify as being key to care‐based processes for managing post‐separation parenting arrangements. Here they had in mind the non‐resident fathers in their study, who were often anxious, angry, and resentful about their diminished fatherhood. Yet gender‐neutral custody laws and the greater prominence given to shared care across the West means that increasing numbers of separated mothers are also experiencing diminished connections to their children, either by becoming non‐resident parents or through shared care arrangements. Research into post‐separation fathers’ and mothers’ experiences of loss and grief in relation to their children is sparse and largely consists of small‐scale qualitative studies focusing either on fathers or mothers. Nonetheless, these studies show that the grief talk of post‐separated parents is strikingly similar, except that mothers who become non‐resident parents commonly talk about a sense of stigma and shame, while fathers are more likely than mothers to resort to the language of anger and rights. Despite Smart and Neale's call roughly 20 years ago, custody law systems across the West continue to neglect parents’ need for recognition and support. This paper seeks to rectify this social neglect through describing a dual program of therapeutically informed interventions with separated mothers and fathers. This is designed to recognise and respond to parental loss and grief experiences, whilst simultaneously fostering personal self‐reflexivity and transformation. The latter is no easy task but is frequently an essential basis for workable co‐parenting post‐separation.     

Patchwork of promises: A critical analysis of immigration policies for unaccompanied undocumented children in the United States

In 2014, the United States saw a greater than 50% increase in the number of unaccompanied children from Mexico and Central America arriving at the U.S./Mexico border, and unaccompanied children continue to migrate to the United States in consistent numbers. The dramatic increase of 2014 exposed gaps in policies aimed at supporting unaccompanied children as they await legal adjudication. This paper begins with a historic review of immigration policies in the United States aimed at supporting unaccompanied migrant children. An analytic review is provided of existing immigration policies in the Department of Homeland Security and the Office of Refugee Resettlement, highlighting the competing paradigms created by missions of security‐focused policy versus child‐centred policy. A close examination of the values that influenced policy development in this area is included, along with a discussion of how social work practice can infuse elements of social justice into immigration policy reform. Areas for future research to reform immigration policy focused on supporting unaccompanied undocumented minors are highlighted.     

“三权分置”制度下农村大学生土地权益保障研究

因户口、职业、经常居住地非农化以及集体义务难以履行等原因,农村大学生的集体经济组织成员权受到质疑甚至否定,导致其土地权益易被侵害。调查结果表明,在“两权分离”制度下,农村女大学生上大学前未分得承包地的比例高于男大学生,农村男大学生上大学后土地权益受侵害与户口迁移正相关,农村女大学生上大学后土地权益受侵害与年龄正相关,经济较发达地区的农村大学生土地权益受侵害的可能性较高。在“三权分置”制度下,应明确在校农村大学生的“集体经济组织成员”身份和“农户家庭成员”身份,即在校农村大学生应与其他村民平等地享有分得承包地的权利、平等地享有土地承包经营权的各种收益,并与其他家庭成员平等地享有承包土地的各项权益;在承包期内(包括延长期),无论农村大学生的身份怎样变化,只要其还是中华人民共和国公民,发包方都不能强制收回其土地承包经营权;同时,要“确地到人、确权到人”,切实保障农村大学生流转土地经营权后获得应有收益,并充分保障上大学前未分得承包地的农村大学生的合法土地权益。     

国有企业的内部人控制研究

内部人控制问题仍然是公司治理中要解决的主要问题,若此问题不设法解决,不但对股东利益有影响,而且还影响着中国资本市场的稳定,影响着中国经济的长足发展。内部人控制的企业并不是直接地、无条件地产生内部人控制问题,因此在界定两者之间的差别的基础上,分析了内部人控制的产生原因及其正负面影响,进而提出解决内部人控制的可行性方法,规范国有企业的公司治理。

裁判执行权的再思考--从权力的个性考察

"执行难"是司法权威受到损害的一个主要因素,解决"执行难"也是当前司法改革的目标之一.而对执行权性质的正确认识是建立合理执行体制的前提和基础.以国家权力的分工与制约理论为基础,从行政权和司法权性质上固有的差别来看,执行权本质上是一种行政权,并不具有任何司法权的特性.由法院行使执行权不仅不会更好地解决"执行难"问题,反而会加剧法院的"行政化"色彩.针对这种状况,合理的解决方法是将执行权从法院剥离出来,交由行政机关行使.
