Museology and Its Others: Analyzing Exhibition Storytelling through Narratology, Space analysis, Discourse analysis, and Ethnographic Research

This chapter aims to investigate how methodologies from fields as diverse as literary studies, art history, exhibition design, sociology, and ethnography can enrich the study of exhibition storytelling. It focuses on fieldwork done in 2020 at the Museum of the Civilizations of Europe and the Mediterranean (Marseille, France) on the semi-permanent exhibition Connectivities. Because of the content and form of the exhibition and the multimodal nature of museum communication, I chose to employ a range of interdisciplinary methods to analyze the exhibition. This enabled me to distinguish my approach from previous practices in museum studies, which, because of the tendency toward “evidenced-based” policies and funding in the cultural field, have frequently adopted a positivist approach to their research. Instead, I aimed to analyze not only the intent of the institution when it comes to narrative production but also its legitimacy to and its impact on audiences

Contrasting multi-taxa diversity patterns between abandoned and non-intensively managed forests in the southern Dolomites

The abandonment of silvicultural activities can lead to changes in species richness and composition of biological communities, when compared to those found in managed forests. The aim of this study was to compare the multi-taxonomical diversity of two mature silver fir-beech-spruce forests in the southern Dolomites (Italy), corresponding to the European Union habitat type 9130. The two sites share similar ecological and structural characteristics, but differ in their recent management histories. In the last 50 years, one site underwent non-intensive management, while the other was left unmanaged and was included in a forest reserve. The species richness and composition of eight taxa were surveyed in the two sites between 2009 and 2011. The difference in mean species richness between the two forest management types was tested through permutation tests, while differences in species composition were tested by principal coordinates analysis and the permutational multivariate analysis of variance. Mean species richness of soil macrofungi, deadwood lichens, bark beetles, and longhorn beetles were significantly higher in the abandoned than in the non-intensively managed forests. Deadwood fungi and epiphytic lichens did not differ in mean species richness between the two study sites, while mean species richness of ground beetles and birds were higher in the non-intensively managed than in the abandoned forest. Significant differences in species composition between the two sites were found for all the taxa, except for longhorn beetles. These results indicate that improving forest landscape heterogeneity through the creation of a mosaic of abandoned and extensively managed forests should better fulfill the requirements of ecologically different taxa

Silvicultural strategies for introduced tree species in Northern Italy

The bio-deterioration of the historical heritage by fast growing and vigorous introduced tree species, and the reduction of native diversity, mostly in riparian, forest, wetland, and coastal habitats are considered amongst particularly relevant impacts for Italy. According to a recent survey of EU Life+ projects, the introduced tree species most often targeted for eradication by conservation projects across Europe are black locust (Robinia pseudoacacia L.), tree of heaven (Ailanthus altissima (Mill.) Swingle), red oak (Quercus rubra L.), and black cherry (Prunus serotina Ehrh.). In this chapter, we report on the few field experiences and success stories of silvicultural control of these introduced tree species in urban and natural habitats in northern Italy

PCSK9 Expression in Epicardial Adipose Tissue : Molecular Association with Local Tissue Inflammation

Epicardial adipose tissue (EAT) has the unique property to release mediators that nourish the heart in healthy conditions, an effect that becomes detrimental when volume expands and proinflammatory cytokines start to be produced. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a proinflammatory mediator involved in atherosclerosis, is also produced by visceral fat. Due to the correlation of inflammation with PCSK9 and EAT enlargement, we evaluated whether PCSK9 was expressed in EAT and associated with EAT inflammation and volume. EAT samples were isolated during surgery. EAT thickness was measured by echocardiography. A microarray was used to explore EAT transcriptoma. The PCSK9 protein levels were measured by Western Blot in EAT and ELISA in plasma. PCSK9 was expressed at both the gene and protein levels in EAT. We found a positive association with EAT thickness and local proinflammatory mediators, in particular, chemokines for monocytes and lymphocytes. No association was found with the circulating PCSK9 level. The expression of PCSK9 in EAT argues that PCSK9 is part of the EAT secretome and EAT inflammation is associated with local PCSK9 expression, regardless of circulating PCSK9 levels. Whether reducing EAT inflammation or PCSK9 local levels may have beneficial effects on EAT metabolism and cardiovascular risk needs further investigations
