Outlining a model of social journalism in health

Social journalism is an emerging field of practice that seeks to reframe journalism as an action-oriented service built on relationships and collaborations, rather than as primarily content or a product. It offers opportunities for innovation that re-centre the public interest roles of journalism at a time when public interest journalism is in crisis. This article outlines a 10-point model for social journalism, drawing on case studies in health journalism connected to the online platform Croakey.org. These case studies show how using decolonising and participatory action frameworks can transform journalism research and practice, with potential benefits for the health and wellbeing of Aboriginal and Torres Strait Islander people. They also illustrate a dynamic process of knowledge exchange between journalism research and practice. Elements of the proposed model for social journalism practice include: standpoint; transdisciplinary practice; connectivity; relationships; responsive listening; reflexivity; immersion; transparency and trust; creativity and innovation; and an ethic of service and outcomes. It is a model in which transformative health journalism facilitates and enables transformation in spheres beyond journalism. This article also considers the constraints and challenges facing social journalism initiatives and practitioners, and makes recommendations for policy

Properties of chemically modified gelatin films

Edible and/or biodegradable films usually have limited water vapor barriers, making it difficult to use them. Thus, the objective of this work was to evaluate the effect of a chemical reticulation treatment with formaldehyde and glyoxal on the mechanical properties, water vapor permeability, solubility and color parameters of gelatin-based films. Formaldehyde and glyoxal were added to the filmogenic solution in concentrations ranging from 3.8 to 8.8 mmoles/100 mL of filmogenic solution and 6.3 to 26.3 mmoles/100 mL of filmogenic solution, respectively. The treatments caused a reduction in permeability to water vapor and in solubility. Only the treatment with formaldehyde caused a significant increase in rupture tension for concentrations above 6.3 mmoles/100 mL of filmogenic solution. Scanning electron microscopy indicated a loss of matrix orientation due to the chemical reticulation treatment
