Quantitative floristics as a tool for the assessment of plant diversity in Tuscan forests
No full textThe results of a floristic survey in six forests owned and managed by the regional administration of Tuscany are reported in this paper. These forests are undergoing a monitoring program, which includes biodiversity as one of the status indicators. Vascular plants are used as indicator species group to quantify biodiversity and they are assessed by means of quantitative floristics. This approach involves the collection of floristic information on the basis of a sampling design. Floristic and structural data were collected in 109 plots, each 400 m2 large, and analysed at both the plot and forest scales. At the plot scale, species richness was found to be unimodally related to elevation and negatively related to tree stem density and total basal area. At the forest scale, the six forests differed in their patterns of species accumulation, with the highest number of species for a given number of sites sampled observed in the intermediate elevation forests. The analysis of the life-form spectrum showed, for both the plot and forest scales, a decreasing importance of the relative abundance of phanerophytes and an increasing importance of the relative abundance of hemicriptophytes in relation to elevation. The use of the approach adopted for future monitoring is also discusse
"And the winners are...": economia, psicologia, scienze sperimentali e finanza
No full textTradizionalmente, le teorie economiche sono state formulate assumendo un soggetto decisionale che sia razionale nell’effettuare le proprie scelte ed agisca in base a propri interessi. Allo stesso modo, l’economia è stata sempre considerata una scienza non sperimentale, basata sull’osservazione diretta del mondo reale . Negli ultimi vent’anni, tuttavia, queste convinzioni sono state in parte riviste: gli esperimenti in laboratorio sono stati riconosciuti come una componente vitale della ricerca economica. il presente contirbuto propone una rassegna critica dei principali contirbuti presenti ed attesi in quest'area di ricerca

Invisible, solidary, unbranded and passionate: everyday life as a freelance and precarious worker in four Italian radio stations
No full textThis article presents an investigation into the everyday lives of freelance radio producers in the Italian radio industry from a perspective that applies the sociology of work to the study of media production. The study adopted an ethnographic approach to explore working conditions and experiences of insecurity, uncertainty, socialising, networking and isolation. The authors identified four features of the radio producers' work, which go well beyond the fact that passion functions as a cover for unfair working conditions. The work of these radio producers is invisible, passionate, unbranded and solidaristic. These features interconnect with the conventional ethos of freelance and precarious workers in the creative industries, where professional identity becomes subsumed by the dominant logic of the industry. If we adopt a Marxist perspective, we could argue that this freelance 'reserve army' experiences a specific kind of 'subsumption' with roots in the workers' teenage fandom-based milieux and in broader popular culture
Il soggetto della teologia e le sue passiones explicabiles in Alessandro Bonini di Alessandria († 1314): Commento alle Sentenze, Prologo, qq. 3-4
No full textThis paper provides a critical edition of the third and fourth questions, on the subject of theology, of the Prologue to the First Book of the Commentary on the Sentences (redactio posterior) by the Franciscan Master Alessandro Bonini of Alexandria († 1314). The seven manuscripts till now known have been used. The introduction tries to put these two questions into the contex of the Prologue, highlighting their main theoretical points
The field as a black box: ethnographic research in the age of platforms
No full textThis article aims to provide a detailed rendering of the struggles we experienced while undertaking ethnographic research for the study of music curators working at online music streaming platforms. Based on the field notes generated during a multi-sited ethnography, the article will critically discuss the “black boxing” strategies employed by these platforms in order to protect themselves from public scrutiny, and how media scholars can counteract in order to (partially) circumvent the restrictions posed by them. In light of this discussion, we propose five tactics that we argue can be employed in order to perform ethnographic research in the age of platforms. We conclude with a reflection on what we can learn from “failures in the field” and why it is important to advance ethnographic studies of the new places of cultural production
