No full textMicrostylium indutum Rondani, 1875 ORIGINAL DESCRIPTION: 1875c: 446. TYPE LOCALITY: “ Insula Bonae Fortunae (Borneo), Provincia Sarawak [Bona Fortuna Island, Sarawak Province, Borneo]” (Rondani 1875c: 421). TYPE MATERIAL: 1 ♂, holotype (MSNG): Borneo, Sarawak, 1865/1866, Coll. Doria / Typus / indutum Rond. / Microstylium indutum n° 45. CURRENT STATUS: valid species (Oldroyd 1975: 120). REMARKS: Rondani (1875c: 446) described Microstylium indutum from just the male sex, without specifying the exact number of specimens and not giving a range of lengths, from material collected by G. Doria and O. Beccari. Guiglia (1957: 195) and Raineri & Rey (1996: 29) reported the holotype (♂) in the MSNG.Published as part of Sforzi, Alessandra & Sommaggio, Daniele, 2021, Catalog of the Diptera types described by Camillo Rondani, pp. 1-438 in Zootaxa 4989 (1) on page 59, DOI: 10.11646/zootaxa.4989.1.1, http://zenodo.org/record/498062
Scritti sulla Toscana. Vol. I - La ricerca sul campo e la «Libera Scuola» di Artimino (1969-2007)
No full textGli Scritti sulla Toscana riproducono la parte essenziale degli studi e degli interventi sull'economia e sulla società toscana di Giacomo Becattini, professore emerito di Economia politica nell'Università di Firenze. Nel primo volume, La ricerca sul campo e la "Libera Scuola" di Artimino (1969-2007), a cura di Fabio Sforzi, si presenta un'originale interpretazione dello sviluppo regionale che ha modificato il quadro degli studi sullo sviluppo economico postbellico dell'Italia
Structure of phytobezoars found in the stomach of a crested porcupine, Hystrix cristata L., 1758
No full textIn this note we describe for the first time the inner structure of bezoars found in the stomach of a free-living crested porcupine. These foreign bodies were composed by three concentric layers made up of vegetal matter. The presence of nettle trichomes in the central core, probably due to an accidental ingestion, may have determined the development of these foreign bodies
A cross-european comparison of three localized industries: The cutlery industry in Maniago (Italy), Thiers (France) and Pavlovo (Russia)
No full textClusters and industrial districts are the two concepts that have changed the way to think about competitiveness. For both, the formation of competitive advantage lies outside the business or industry, residing in the surrounding environment to which the firm or the industry belongs. Nevertheless, between the two concepts, there are differences in how they define the nature of the surrounding environment: a spatial concentration of productive activities, in the case of cluster; a local community, for the industrial district. From a historical perspective, these differences are the basis of three different approaches to the problem.
The first approach, more and more prevalent, tends to deny the existence of differences, going to identify the cluster with the industrial district, paying full attention of the historical research on the genesis and evolution of the spatial concentration of production.
A second approach identifies the district as a special case of cluster, in which the long duration and evolution have led to exceptional socio-cultural conditions that are hardly replicable elsewhere.
Finally, a third approach makes the district and the cluster out to be two distinct concepts by identifying the local community – and its related socio-cultural features based on a value system that foster industrial skill and business ability – as the founding component of the district. So that, according to this approach the productive apparatus is considered the outcome of a process of industrial specialization and organization of the local community. This third approach, therefore, establishes a logical gap between the concept of cluster and district; and, in the extreme, it may even belong to two different disciplines: to the business history, the cluster; to the economic and social history, the district. This paper is part of the latter approach. It comparatively analyses historical trends of cutlery industry in Maniago (Italy), Thiers (France) and Sheffield (England) to found empirically the reasons that make the district a more robust theoretical paradigm than the cluster in the understanding how competitive advantage is formed and reproduced over time
I sistemi locali del lavoro. Censimento 2001. Dati definitivi
No full textI Sistemi Locali del Lavoro (SLL) rappresentano i luoghi della vita quotidiana della popolazione che vi risiede e lavora. Si tratta di unità territoriali costituite da più comuni contigui fra loro, geograficamente e statisticamente comparabili. I Sistemi Locali del Lavoro sono uno strumento di analisi appropriato per indagare la struttura socio-economica dell’Italia secondo una prospettiva territoriale. Lo studio che ha portato all’individuazione dei Sistemi Locali del Lavoro è l’esito di un accordo di ricerca fra l’Istat e il Dipartimento di Economia dell’Università di Parma. Il progetto si colloca lungo una linea di continuità scientifica e metodologica con le precedenti esperienze che l’Istat aveva già condotto nel 1981 e nel 1991 in collaborazione con l’Irpet e le Università inglesi di Newcastle upon Tyne e di Leeds. Questa è, infatti, la terza volta che l’Istat individua i Sistemi Locali del Lavoro. I Sistemi Locali del Lavoro 2001 sono stati individuati sulla base dei dati relativi agli spostamenti quotidiani per motivi di lavoro, rilevati in occasione del 14° Censimento generale della

Site selection and fidelity by crested porcupines for denning
No full textThe crested porcupine is a large rodent living in Central and North Africa, with a European distribution limited to Italy. Its biology and particularly its denning habits are inadequately known. Our study was carried out in a Mediterranean coastal area of central Italy. We radiotagged 13 adult porcupines, assessing their den site selection and use each month, from February 1998 to September 1999. Porcupines preferred steep, compact soils covered with dense vegetation, for denning. Each den was always used by the same 2 individuals, possibly forming a reproductive pair. Paired individuals seemed to show a greater site fidelitythan single ones. Intepretations of this behaviour are discussed
Chemical immobilization of crested porcupines with Tiletamine HCl and Zolazepam HCl (Zoletil®) under field conditions
No full textThe combination of tiletamine HCl and zolazepam HCl has been used on many species of wild mammals. Short induction time, low dosage, satisfactory safety margins, relatively constant immobilization time, and smooth recovery are benefits reported. This combination (Zoletil® 100) was used during a study on behavioural ecology of the crested porcupine (Hystrix cristata) in a Mediterranean coastal area (Maremma Regional Park, Tuscany, Italy). We used this mixture 42 times on 31 individuals. Mean adult dose was (±SE) 7.24±0.37 mg/kg (74.0±3.0 mg/individual). Average adult induction time was 5.3 min (±1.1) and average adult immobilization time was 22.6 min (±6.0). One adult male porcupine died after chemical restraints. The use of tiletamine-zolazepam seems adequate for chemical immobilization of crested porcupines under field conditions, mainly because of its short induction time, small volume to be injected and wide safety margin. © Wildlife Disease Association 2003
Rethinking the industrial district: 35 years later
No full textEl año 2014 marcó un doble aniversario: los del 35.º y 25.º año de la publicación de dos trabajos seminales de Giacomo Becattini sobre el distrito industrial. El primer artículo (Becattini, 1979) conceptualiza el distrito industrial como una «unidad de investigación», mientras que el segundo (Becattini, 1989) conceptualiza el distrito industrial como un «modelo de producción». Entre los dos artículos hay una dependencia mutua. El distrito industrial como «modelo de producción» privado del distrito industrial como «unidad de investigación» pierde su originalidad como una forma de interpretar el cambio económico y se convierte simplemente en «un tipo de clúster». Este artículo trata la relación entre el distrito y el clúster, y a continuación entre el distrito industrial como un constructo teórico único y los muchos distritos industriales como resultados de investigaciones empíricas, y concluye con algunas observaciones sobre la actua-lidad del distrito industrial
