A formative evaluation of the recovery public works programme in Blantyre City,Malawi

Public works programmes (PWPs) are popular social protection instruments in the context of chronic poverty but very little has been published in the way of implementation and outcomes of these programmes. This paper presents a formative process and outcome evaluation of the recovery PWP in Blantyre City, Malawi. The evaluation used longitudinal household survey data of PWP beneficiaries, programme records and interview responses from programme staff and community leaders. Largely, the process evaluation findings showed an agreement between actual and planned activities. The outcome evaluation found indications that the PWP community assets offered some potential benefits to the communities, and that PWP wages allowed the beneficiaries to purchase some food. This however, did not translate into more meals per day, nor did the earnings prevent the decline in household assets as expected. Given a plausible PWP theory and high implementation fidelity, the PWP wage rate or number of days was either just enough to smooth participant income, or insufficient altogether, to enable achievement of more distal outcomes.     

Problems and Solution for Criminal and Attached Civil Procedure on Juvenile Delinquency Cases According to

2012年修改的我国《刑事诉讼法》实施后,未成年人犯罪案件刑事附带民事诉讼中可能存在“合适成年人”无法作为民事诉讼法定代理人以维护有关未成年人民事权益、适用“当事人和解的公诉案件诉讼程序”时将被告人赔偿与否作为量刑情节而造成对被告人不公、适用“简易程序”时法官施压调解而干预阻碍被告人行使民事诉讼权利、审判人员能否兼备审理刑事案件与民事案件的专业素养等问题。为了在发挥刑事附带民事诉讼制度优点的同时一定程度上控制其缺陷所造成的不利影响,司法解释应规定在未成年人犯罪案件中,刑事附带民事诉讼制度不适用于刑事附带民事诉讼的民事部分标的金额较大的情形、被告人可能被判处较重刑罚的情形、刑事附带民事诉讼的刑事部分与民事部分审级不一致的情形、案件审理时间较长的情形。     

现代信息查询领域知识体系探讨

在现代网络环境下,传统的文献检索范围已迅速拓展到现代信息查询领域,作为大学信息教育的课程——《文献检索与利用》,其知识体系面临淘汰陈旧知识、更新内容、体系结构优化重组的课题。本文针对这一目标,对现代信息查询领域知识体系作了初步的探讨。     

Improving variance function estimation in semiparametric longitudinal data analysis

We propose an efficient and robust method for variance function estimation in semiparametric longitudinal data analysis. The method utilizes a local log‐linear approximation for the variance function and adopts a generalized estimating equation approach to account for within subject correlations. We show theoretically and empirically that our method outperforms estimators using working independence that ignores the correlations.

YAG:RE3+(RE=Eu,Tb)的制备及发光特性研究

利用柠檬酸-凝胶方法,以Y2O3,Eu2O3,Tb4O7和Al(NO3)3·9H2O作为初始原料,柠檬酸作为配位剂,成功制备出了Y3Al5O12:Eu3+(Tb3+)发光材料,其烧结温度为1?000℃,时间4?h.通过X射线衍射测试,表征Y3Al5O12为单相;计算其晶胞参数,发现晶胞体积v随着pH值的增大而增大.对Y3Al5O12:Eu3+(Tb3+)系列样品在紫外光谱区域和真空紫外光谱区域的发光性能进行了研究,结果表明:在真空紫外光谱区域激发下,Eu3+(Tb3+)的猝灭浓度比在紫外光谱区域激发下的低.
