Recreating Social Capital

ABSTRACT

This paper describes the establishment of a pilot neighbourhood-based intergenerational programme and its evaluation in one town in England. It sets this in both the context of English inter-generational programmes involving schools and of English social policy. The latter is currently influenced by Putnam's concept of social capital. It argues that intergenerational programmes of all kinds are likely to be useful contributions to the development of social capital. The paper reports how the evaluation of the pilot has lead to the refinement of the original model. The pilot highlighted the need for more systematic measures of the process and outcomes, including the project's contribution to development of social capital. The revised model is being implemented in a number of contrasting neighbourhoods and will be evaluated in both outcome and process terms. These developments will be reported in further articles.

Collaboration as a strategy to accelerate change

Abstract

As a strategy, collaboration is increasingly recognized by governments and by library partnerships as a critical component in achieving next generation change, particularly where it leads to trust in shared infrastructure, collections and expertise. Collaboration reduces the risks to the library industry. These risks stem from the capability of libraries to respond rapidly to changing technology and user needs, and to drive an increase in the digitization of collections and ensure the preservation of digital content. The ten National, State and Territory Libraries of Australia and New Zealand have committed to collaboration to accelerate change in their libraries and to new principles of open and easy access to information. The challenge is to bring these elements together as a transformed and implemented service.     

Collaboration in EU Framework Programmes – the case of the social sciences and humanities

The impact of the European Framework Programme (hereafter FP) projects is usually measured with reference to the possibilities offered for collaboration. In this research note we take a different perspective and explore the extent to which FPs have influenced the traditional performance of researchers and vice versa. The population reference for our study consists of the projects funded within the EU Sixth Framework Programme (FP6) between 2002 and 2006. Here, we have concentrated our analysis on the priority area of “citizens and governance in a knowledge-based society” (CIT).     

The Hutubi Model: what have we learned?

Created to address some of the limitations in China's rural retirement insurance policy, the Hutubi Model represents an innovative approach to asset building. A key feature of the model, the Hutubi loan programme, operated in Hutubi County, Xinjiang, China, from 1998 to 2010. It allowed farmers in Hutubi to borrow against their rural retirement accounts, taking loans for investment in farming and other priorities. This study examines the institutional incentives and structures that enabled the programme to help farmers build assets. We also discuss the programme's implications for the development of asset-based social policy in rural China and consider recent policy developments there. Among these is a new rural retirement social insurance programme.     

VB课程多媒体教学系统设计与实现

目前多媒体课件制作常用的工具主要有两大类:一类是可视化编程语言如Visual Basic,Visual C 等;另一类是多媒体创作工具如PowerPoint、Flash、Authorware等。用单一的制作工具来开发教学软件总是有些不足,若能将这些开发工具进行综合利用,取长补短,必能开发出更好的多媒体教学课件。VB是一门大学计算机基础课程,适用对象广,课堂教学采用多媒体教学方式。作者利用综合设计课件的方法制作了VB课程多媒体教学系统,系统功能模块主要有课前提问、进入课堂、布置作业、课后自测、教学大纲、教学进度、实验提示、实验视频、课堂视频、作业答案等。为多媒体教学系统设计与实现提供了清晰有效的制作方案。

The effects of vocational training programmes on the duration of unemployment in Eastern Germany

Summary Vocational training programmes have been the most important active labour market policy instrument in Germany in the last years. However, the still unsatisfying situation of the labour market has raised doubt on the efficiency of these programmes. In this paper, we analyse the effects of the participation in vocational training programmes on the duration of unemployment in Eastern Germany. Based on administrative data for the time between the October 1999 and December 2002 of the Federal Employment Administration¹, we apply a bivariate mixed proportional hazards model. By doing so, we are able to use the information of the timing of treatment as well as observable and unobservable influences to identify the treatment effects. The results show that a participation in vocational training prolongates the unemployment duration in Eastern Germany. Furthermore, the results suggest that locking-in effects are a serious problem of vocational training programmes. The authors thank Heinz Galler and an anonymous referee for valuable comments. The paper has also benefited from fruitful discussion at the annual meeting of the German Statistical Society in 2004, Frankfurt, and in IZA seminar, Bonn. All remaining errors are on our own.

论坚持党的最低纲领与最高纲领的统一

党的最低纲领与最高纲领的统一,是由党的长远目标的确定性和实现长远目标的阶段性决定的。回顾中国共产党处理最低纲领与最高纲领相互关系的历史,总结党在这个问题上的历史经验和教训,对于今天坚持党的最低纲领与最高纲领的统一,具有重要的现实意义。
