fall into the same rational group as Chinese immigrants. Given the very low levels at which the traditional, low-educated group partakes in supplementary education (the authors report that only one in twenty Mexican-immigrant offspring receive it), compared to the Asian groups (one in four for Koreans and Taiwanese, and one in six for Vietnamese), we would again caution against generalizing from their conclusion. Despite these and similar limitations, Luthra, Soehl, and Waldinger have judiciously laid out a sociology of the second generation. Origins and Destinations offers a wealth of evidence to support secondgeneration assimilation. While we expect continued lively debate over theories of assimilation-with particular attention to inter-group and intra-group variation-the authors have offered thought-provoking ideas about how to incorporate origins, destinations, and the interplay of the two at different levels of analyses to understand the new second generation.
There is a growing recognition in developing countries of community-based infrastructure procurement and its potential to achieve sustainable development. The advantages of such an approach are that it encourages participative negotiation of activities and speedier implementation, the use of local resources, skills and appropriate technology, and entrepreneurship within communities. These wider socio-economic impacts arising from community-partnered micro-projects can lead to more sustainable infrastructure through meeting local stakeholders' needs, community empowerment and capacity building. This paper describes the development and use of performance indicators for community-contracted urban infrastructure provision in low-income communities in India, Pakistan and Sri Lanka. In particular, these indicators refer to the dimensions of time and cost; some key performance yardsticks are also proposed. The urban infrastructure and services referred to in these cases are the facilities needed for water and sanitation provision, access roads, street lighting and solid waste management. In general, it was found that costs for community-contracted micro-projects were normally very close to being on target. The quality of infrastructure and service provision also tended to be superior to that envisioned by local government engineers. However, project duration generally exceeded the target but was still comparable to conventional contracts. The overall performance of the community-partnered micro-projects was found to be comparable or better than the conventional micro-contracts; in addition, the performance of these projects in terms of socio-economic elements was likely to far exceed that of the conventional micro-projects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
