Telling and Re‐telling Stories: The Use of Narrative and Drawing in a Group Intervention with Parents and Children in a Remote Aboriginal Community

The Let's Start Parent‐Child Program is a manualised parent‐child program which aims to improve educational, social and emotional outcomes for Aboriginal parents and their four‐ to seven‐year‐old children. It has been implemented in the Northern Territory, Australia on the Tiwi Islands and in Darwin since 2005. This paper outlines the adaptation of the program to include narrative approaches, the sharing of stories and the use of expressive arts as a way to build understanding between program leaders and participating families. An example from a recent program is used to illustrate how the sharing of stories and expressive use of art engages and binds group participants together. It supports parents to tell their own stories, to speak about their lived experience, to reconsider aspects of their own and their children's experiences and to achieve an increased awareness of their personal resources and a sense of self‐empowerment. The program is designed and delivered with sensitivity to individual parents, children and families, where cultural and interpersonal differences and different developmental and family situations can be taken into account.     

Observational sketching as method

This paper explores the potential of observational sketching as a social science research tool, informed by our own recent experiments with observational sketching techniques and approaches. We first outline the historical roots of academic sketching and note a recent resurgence of interest in sketching in certain disciplines. We then introduce our own explorations in sketching as method, based on a year-long collaboration between an observational artist and a group of qualitative researchers with interests in creative methods. The paper outlines some of the lessons we learnt from our partnership, focusing on three themes: (i) ‘sketchiness’; (ii) ‘concentrated seeing’ and (iii) sketching as interaction. We conclude that observational sketching generates a refreshingly different form of visual data which has considerable potential to be used as a complement to other methods, including as a participatory method and as a useful tool for thinking.     

How the host nation's boundary drawing affects immigrants’ belonging

Across Western democracies, the place for newcomers in the host society is debated, involving often a questioning of immigrants’ belonging to their new nation. This article argues that immigrants’ feeling of host national belonging depends on how the host nation imagines its community and its concomitant boundaries. Utilising survey and country level data in multilevel regressions, immigrants’ belonging is found to vary significantly across the 19 countries included. A central contribution is the finding that citizenship policies do not explain this cross-national variation. Instead, what matters is the informal boundary drawing produced in the majority population's conception of what is important for being part of the national ‘us'. Thus, immigrants’ belonging is significantly greater when the majority population prioritises attainable criteria of national membership. In addition, these priorities are shown to have deep historical roots as immigrants’ belonging is greater in settler countries and in nations which democratised early. By showing that national imageries have consequences for a country's welcoming capacities, and by showing that these welcoming capacities are historically path dependent, the study contributes to the debate within nationalism studies about national identity's causal significance.
