Applying systems theory to the evaluation of a whole school approach to violence prevention

Issue addressed: Our Watch led a complex 12-month evaluation of a whole school approach to Respectful Relationships Education (RRE) implemented in 19 schools. RRE is an emerging field aimed at preventing gender-based violence. This paper will illustrate how from an implementation science perspective, the evaluation was a critical element in the change process at both a school and policy level. Methods: Using several conceptual approaches from systems science, the evaluation sought to examine how the multiple systems layers – student, teacher, school, community and government – interacted and influenced each other. A distinguishing feature of the evaluation included ‘feedback loops’; that is, evaluation data was provided to participants as it became available. Evaluation tools included a combination of standardised surveys (with pre- and post-intervention data provided to schools via individualised reports), reflection tools, regular reflection interviews and summative focus groups. Results: Data was shared during implementation with project staff, department staff and schools to support continuous improvement at these multiple systems levels. In complex settings, implementation can vary according to context; and the impact of evaluation processes, tools and findings differed across the schools. Interviews and focus groups conducted at the end of the project illustrated which of these methods were instrumental in motivating change and engaging stakeholders at both a school and departmental level and why. Conclusion: The evaluation methods were a critical component of the pilot’s approach, helping to shape implementation through data feedback loops and reflective practice for ongoing, responsive and continuous improvement. Future health promotion research on complex interventions needs to examine how the evaluation itself is influencing implementation. So what? The pilot has demonstrated that the evaluation, including feedback loops to inform project activity, were an asset to implementation. This has implications for other health promotion activities, where evaluation tools could be utilised to enhance, rather than simply measure, an intervention. The findings are relevant to a range of health promotion research activities because they demonstrate the importance of meta-evaluation techniques that seek to understand how the evaluation itself was influencing implementation and outcomes.

Educational leadership and Nancy Fraser

Drawing on the work of Nancy Fraser, this book offers a critical view of contemporary educational leadership and reform discourses, exploring how her key concepts of redistribution, recognition and representation may apply to social and therefore educational justice.Fraser offers a political and pragmatic reconciliation between feminist, neo-Marxist, critical and post-structuralist theories. This book outlines how Fraser has worked on and worked over theories of social justice and how this can inform how we can understand educational theory, policy and practice generally. In particular, the book focuses on the field of educational administration and leadership (ELMA) as it relates to equity issues such as school choice and inequality, gender and inclusive leadership, and alternative schooling. Fraser’s argument about ‘scaling up’ social justice theory is shown to be highly salient given the emergence of the field of transnational education policy and its role in the context of intensified nation-state and edu-business competition.Overall, through the lens of Nancy Fraser’s unitary framework, this book considers epistemological questions about the nature of knowledge, examines the relationship between the state, the individual, education and social movements, addresses the difficulties and dilemmas which arise due to the intersections of gender, class, race, sexuality and culture in a globalized context, and illustrates how the principles of social justice can be mobilized by leaders in everyday practice.

On the race of worms and patches: modeling the spread of information in wireless sensor networks

Sensor networks are a branch of distributed ad hoc networks with a broad range of applications in surveillance and environment monitoring. In these networks, message exchanges are carried out in a multi-hop manner. Due to resource constraints, security professionals often use lightweight protocols, which do not provide adequate security. Even in the absence of constraints, designing a foolproof set of protocols and codes is almost impossible. This leaves the door open to the worms that take advantage of the vulnerabilities to propagate via exploiting the multi-hop message exchange mechanism. This issue has drawn the attention of security researchers recently. In this paper, we investigate the propagation pattern of information in wireless sensor networks based on an extended theory of epidemiology. We develop a geographical susceptible-infective model for this purpose and analytically derive the dynamics of information propagation. Compared with the previous models, ours is more realistic and is distinguished by two key factors that had been neglected before: 1) the proposed model does not purely rely on epidemic theory but rather binds it with geometrical and spatial constraints of real-world sensor networks and 2) it extends to also model the spread dynamics of conflicting information (e.g., a worm and its patch). We do extensive simulations to show the accuracy of our model and compare it with the previous ones. The findings show the common intuition that the infection source is the best location to start patching from, which is not necessarily right. We show that this depends on many factors, including the time it takes for the patch to be developed, worm/patch characteristics as well as the shape of the network.

Mobilising spaces of agency through genealogies of race and gender: issues of indigeneity, marginality and schooling

This article presents data from a case study of a non-traditional secondary school for Indigenous girls located in a suburban area of Queensland (Australia). The focus is predominantly on the identity and practices of Nicole who is one of the school’s teachers. Nicole’s identity as an Indigenous woman and teacher and the school’s approach to supporting its marginalised students are theorised in relation to particular elements of feminist genealogy. These elements are associated with the possibilities for agency opened up through the subject’s critical reflection on, and resistance of, the discursive relations that constitute the self. The article draws on feminist theories to explicate the potential of such reflection and resistance to disrupt and transform gendered and racist norms and to legitimise alternative constructions of female indigeneity – to that represented in dominant colonial discourse.
