Learning from Experience in Family Support Programs

ABSTRACT

The paper describes three related California family support program initiatives representing field experiments in program development and policy related to reducing adverse outcomes for vulnerable families through replicating known “best practices” models. The ways in which the three initiatives were affected by the context of implementation are used to demonstrate the difficulty both of identifying the “best” program models and the need for leadership at all levels in order to develop programs and policies, which achieve the intended effects.     

Negotiated Project Engagements: Learning from Experience

How far is it possible to capture the lessons tobe drawn from successive projects that involveintervention by social scientists within or betweenorganizations, whether acting as researchers, asconsultants, as agents of change, or in some combination ofthese roles? This paper outlines the way in which aframework was developed, by staff and associates of TheTavistock Institute, for examining the varied and often subtle influences of successive“negotiated project engagements” on thedevelopment of wider personal, institutional, anddisciplinary programs. This framework is designed totake into account the contrasting perspectives of the investigatorsthemselves, of their organizational hosts, and of anyexternal sponsors whose primary concern will normally bewith project outcomes at a more generalized level. As an illustration, particular reference ismade to the experience of a pioneering project concernedwith policy-making in city government. This project wasundertaken to advance the understanding and practice of public planning, while also exploring thepotential for synergy between the perspectives ofoperational research and applied social science. Thepaper concludes with some speculations about thepotential for further developing this kind of frameworkin supporting experiential learning.

Reconstructing Adolescence after Displacement: Experience from Eastern Africa

In this article I am concerned to explore the ways in which war and forced migration have impacted on traditional ideas and practices surrounding adolescence and, as a consequence, influenced actual lives. A particular focus is given to the roles and responsibilities of adolescents, for whom a tension often exists between the pressures to achieve social adulthood and to gain assistance through presenting themselves as children. Their quest to achieve adulthood is often hampered by the abandonment of initiation practices due to the conditions of conflict and displacement. At the same time military mobilisation and the work of international humanitarian organisations provide new avenues for the possible enhancement of their social status. This article provides examples from across the region that illustrate the ways in which adolescence itself is being reconfigured as a result of these changes.     

The Experience of Higher Education from the Perspective of Disabled Students

This article describes the findings and examines the issues arising from a small-scale investigation into the experience of higher education from the perspective of disabled students at a university in the United Kingdom, and makes recommendations for policy and practice. Methodology involved semi-structured interviews with participants to reveal individual experience and analysis of relevant documentation from the university to examine the rhetoric underlying their experience. Factors that create a positive experience for disabled students, and those which effect discriminatory practice and marginalisation are identified. The implications of the findings for policy and practice are discussed, and conclusions drawn including: the need for a central policy which supports the philosophy of an accessible learning environment for all students; central co-ordination to implement the policy with practical guidelines to departments; ongoing monitoring and evaluation procedures which involve disabled students; staff training and awareness; student advocacy.
