In journalism, we are all men: material voices in the production of gender meanings

This study uses qualitative data to examine how male and female professionals in newsrooms experience and vocalize gender both in their lifeworlds and in media production in general. The research was based on semi-structured interviews with 18 Portuguese journalists. The responses were analysed through phenomenological and feminist lenses and indicated the issues men and women considered salient or negligible within our realms of inquiry. The study used the lived experience of the media professionals to identify two clusters of meaning that help explain how material practices and norms in journalism are lived and understood in the newsroom: gender views in journalism and gender differences in day-to-day professional life. Overall, the findings confirm that organizational factors and the traditional gender system play important roles in journalists’ attitudes and perceptions about the role of gender in their work. The results are significant because they show how gender is simultaneously embodied and denied by both female and male journalists in a process of phenomenological “typification” and adoption of a “natural attitude” towards the gender system that may prevent the disclosure of new possibilities and understandings of the objective social world and of our gender relations.

Molecular mobility, composition and structure analysis in glycerol plasticised chitosan films

This study was developed with the purpose to investigate the effect of polysaccharide/plasticiser concentration on the microstructure and molecular dynamics of polymeric film systems, using transmission electron microscope imaging (TEM) and nuclear magnetic resonance (NMR) techniques. Experiments were carried out in chitosan/glycerol films prepared with solutions of different composition. The films obtained after drying and equilibration were characterised in terms of composition, thickness and water activity. Results show that glycerol quantities used in film forming solutions were responsible for films composition; while polymer/total plasticiser ratio in the solution determined the thickness (and thus structure) of the films. These results were confirmed by TEM. NMR allowed understanding the films molecular rearrangement. Two different behaviours for the two components analysed, water and glycerol were observed: the first is predominantly moving free in the matrix, while glycerol is mainly bounded to the chitosan chain.
