The ‘right time’ – negotiating the timing of interviews with vulnerable young people

Participant retention is a key factor in determining the success of longitudinal research. Challenges in re-locating and retaining participants over the long term are major issues for researchers working with young people who face adversity and experience frequent changes in circumstances. This article reports on a study of vulnerable young people and their transition into adulthood. Rather than the more conventional schedule-based approach to locating and re-interviewing young people, a relational process, the ‘right time’ framework, was used to facilitate young people's involvement in the study. Embedded in the ‘right time’ framework is recognition of the diverse and fluctuating circumstances that shape young people's availability for interviews. Several case examples are considered which amplify the way that the ‘right time’ framework allowed the research to navigate around these circumstances. The case examples highlight the value young people attached to being involved in the research, the influence on the ‘right time’ of wider relational tensions for young people and the need to negotiate researcher status as a different sort of adult. The ‘right time’ framework contributed to a high retention rate in the study generating a more representative sample and enhancing the subsequent data analysis by providing valuable insights into the lives of these vulnerable young people.     

基于评价理论的APEC领导人宣言分析

2005年到2014年的APEC领导人宣言中的评价资源以借言为主，正面评价突出，其中鉴赏资源丰富，语势较强，立场分明。这些既体现出对话的和谐，又表明了领导人的决心和信心。2014年的领导人宣言的特点是亚太国家成果众多且认可度更高，特别鼓励区域内，以及政府与私营企业的战略性合作。     

Heteroscedastic Global Tests that the Regression Parameters for Two or More Independent Groups are Identical

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad leverage points. The method used to identify leverage points can be important and can improve control over the Type I error probability. Results are illustrated using data from the Well Elderly II study.     

湖北省乡镇企业1978—2002年发展概况、问题及对策研究

1978～2002年,湖北省乡镇企业在企业单位数量、对经济增长贡献及转移农村剩余劳动力等方面对该省经济产生了重要的推动作用。然而,随着市场经济体制的深入发展和不断完善,乡镇企业发展也遇到了前所未有的困难。本文在深入分析当前乡镇企业所面临的问题基础上,提出了乡镇企业未来发展的战略对策。     

基本剩余价值初探

剩余价值在其历史发展中相继地采取了绝对剩余价值、相对剩余价值和基本剩余价值的直接表现形式。基本剩余价值是在绝对剩余价值和相对剩余价值尚未产生或产而复失的历史场合中必须生产的 ,也是在实行绝对剩余价值生产和相对剩余价值生产的历史场合中 ,被它们凸现出来并使它们赖以产生的具有原先既定性 ,或扩张基础性和增生本体性的剩余价值形式。基本剩余价值生产与资本主义生产相始终 ,是资本主义生产目的的基本实现。它和绝对剩余价值、相对剩余价值在质和量及其历史形态上的差异 ,使剩余价值成为一个比较经济范畴     

Theoretical consideration of effect of fishing mortality on growth and reproduction of fish populations

Summary An increase in fish mortality due to fishing can theoretically change the growth and reproduction of fish populations from the viewpoint of adaptation. We address the issue of how an iteroparous fish should convert surplus energy into somatic growth and reproduction at each age under given conditions of mortality. A model of life history, which maximizes the net reproductive rate using the discrete maximum principle, is improved employing a new relationship between body weight and surplus energy which we have recently proposed. The model is applied to the North Sea plaicePleuronectes platessa, for which it has been reported that the average length of young fish had increased whereas that of old ones had decreased for some decades. Although the model cannot directly explain the former phenomenon, the two phenomena can be interpreted as a change in the optimal life history due mainly to an increase in mortality.     

试论我国农村剩余劳动力的迁移聚集与小城镇发展

农村剩余劳动力档案管理信息系统初探

实现农村劳动力的有效转移 ,需要宏观政策的引导 ,更需要微观措施的落实。本文提出建立档案式管理的诚信打工用工管理服务机制 ,既是微观管理措施的设计 ,也是宏观方针策略的探讨 ,寻求宏观政策与微观措施的有机结合 ,充分发挥宏观与微观的整合功能 ,促进农村剩余劳动力的有效转移     

晋察冀边区的“三三制”村政权建设

村政权是抗日民主政权的基石。晋察冀边区经1938-1940年村政建设,广大乡村实现了由村长制到村民委员会制的过渡,大批抗日人士走上了村长的岗位。为推进全民族抗战和边区民主建政进程,1941年之后的晋察冀边区村选贯彻了"三三制"思想,在更加扩大的民主范围和统一战线的基础上进行村政建设。村级抗日民主政权的"三三制"建设,表明中国共产党人政权观日渐成熟。它适应了全民族总动员的抗日斗争的客观需要,适应中国社会阶级构成"两头小中间大"的国情,使各抗日阶级、阶层、党派代表进入基层抗日民主政权的领导,行使议政从政的权利,促进了乡村社会治理,从而极大地激发了乡村民众的抗日救国积极性,为夺取抗日战争的胜利发挥了十分重要的作用,为解放区和新中国成立后村政建设积累了经验,树立起了"模型"。     

“健康丝绸之路”构建的“政府—社会”复合路径

借鉴社会运动理论,可探索一种融合了政府自上而下和社会自下而上进程的“政府—社会”复合路径,以构建“健康丝绸之路”。社会运动理论的三种视角可为这种复合路径的具体实施与需要关注的环节带来重要启发：首先,当前新冠肺炎疫情的跨国传播暴露了全球公共卫生治理体系存在的严重不足,凸显出构建补充型国际卫生合作模式的必要性与紧迫性;其次,推进“健康丝绸之路”的构建,需要政府和社会层面的协作,将“一带一路”沿线国家的资源充分调动起来,形成优势互补与资源共享。与此同时,要推进健康话语体系的完善,如倡导和促进“人类卫生健康共同体”理念的传播,通过话语和心理共鸣等民心相通的途径,促使国际社会采取联合行动以共同应对全球公共卫生危机。
