“Montrose” child life protection unit: A treatment and assessment model in child abuse intervention

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.

现代远程教育校外学习中心模式及对自学考试的启示

我国的现代远程教育经过近十年的发展,已经取得了很大的成绩。校外学习中心模式已经逐步建立起来,并已成为支撑远程教育的重要形式之一。校外学习中心模式吸收了国外开放大学学习中心模式的精髓,有着明显的中国特色。本文从"学习中心"的起源、职能、运行模式等方面对校外学习中心模式进行了全面的分析,并提出该模式对自学考试完善社会化学习支持服务体系在两方面有重要启示作用。一是,校外学习中心市场化的运作模式及其组织保障系统;二是,服务的思想和力度可以通过学习中心模式得到更好的实现和加强。

Distributing and Showing Farmer Learning Videos in Bangladesh

Purpose: To describe the results of showing farmer learning videos through different types of volunteers.

Design/Methodology/Approach: Semi-structured interviews with volunteers from different occupational groups in Bangladesh, and a phone survey with 227 respondents.

Findings: Each occupational group acted differently. Shop keepers, tillage service providers, agricultural input and machine dealers reached fairly small audiences. Tea stall owners had large, male audiences. Non-governmental organisations and community-based organisations, reached more women. The cable TV (dish-line) operators showed the videos on local TV, but some were reluctant to do so again. The Union Information Service Centres showed the videos and reached women viewers. Half of the official government extension agents surveyed also showed the videos publically.

Practical Implication: This video featured maize, wheat and rice seeding machinery. Because the machinery is complex and requires hands-on training, this first video aimed to expose tillage and sowing service providers and farmers to the machinery, without trying to teach them how to use it. But some farmers were so interested that they watched the video many times to learn more about the equipment. Before farmers and service providers decide to buy machinery for direct seeding, they still want to see and learn from demonstration plantings, to examine first-hand how the crop behaves when planted with the new equipment.

Originality/Value: Video can be an effective way of sharing high-quality information with a large audience, if properly distributed.     

Virtual and Dynamic Hierarchical Architecture:an overlay network topology for discovering grid services with high performance

INTRODUCTION Grid (Foster et al., 2001) technology is one ofthe most important ones to appear in recent years.The recent big progress is that scientists (Foster etal., 2002; Roure et al., 2001; Rana and Walker,2002) proposed service-oriented architectures suchas Open Grid Services Architecture (OGSA) (Fos-ter et al., 2002) that integrated the so-called com-putational/data Grid architecture (Foster et al.,2001) with Web services (Grid Web ServicesWorkshop, 2001).
