Get PDFA Multimedia Q Methodology Investigation of the Degrowth Concept Among Young French Citizens
Get PDFThe acceleration of research efforts dedicated to degrowth has been noticeable since 2012, along with a growing public interest. While there are many definitions of the degrowth notion, Schneider et al. (2010) define it as "an equitable downscaling of production and consumption." Many views and discourses on degrowth exist but we can wonder to what extent people perceive different aspects of degrowth and its implications. These views and representations of the concept can be sketched by verbal, visual or even auditory stimuli. For that reason, we describe a two-part multimedia Q-methodological investigation of degrowth based on statements, pictures and sounds. In the first part, young French citizens trained in sustainable development project management completed three Q sorts with separate Q samples, each comprised of statements, pictures or sounds. In the second part, a different set of participants completed a follow-up study with just a picture Q sample. Eight subjective views of degrowth were identified: institutional, idealistic, back to nature and pacifist, consumption-aware, activist, analytical realistic, socio-degrowth, and holistic. Two of them were captured only though non-verbal stimuli
Antifungal Activity in Extracts of Plants from Southwestern Oklahoma Against Aspergillus Flavus
Get PDFThe use of medicinal plants has been an integral part of human civilization since antiquity. Naturally occurring pesticidal compounds are synthesized by the plant defense system, which includes antimicrobial proteins and lower molecular weight natural products. In this study, plants were collected from southwestern Oklahoma, and plant tissues were extracted and assayed for antifungal activity against Aspergillus flavus, a mycotoxin producing fungus. Out of the 84 plant tissue extracts tested, 40 extracts exhibited complete to very strong inhibition of fungal growth. Extracts were dialyzed in Tris buffer using 3,500 molecular weight cut-off dialysis membrane to remove low molecular weight compounds. After dialysis, the majority of the plant extracts lost antifungal activity against A. flavus. Four plant extracts, however, retained complete activity. The source plants of these four extracts were identified as belonging to Asparagaceae. Three of the extracts came from three different plants of the genus Allium. The fourth extract was from Camassia scilloides
