Farm tourism: a cross-country empirical study in Germany and Italy

PROBLEM In the last few years farm tourism or agritourism as it is also referred to has enjoyed increasing success because of its generally acknowledged role as a promoter of economic and social development of rural areas. As a consequence, a plethora of studies have been dedicated to this tourist sector, focusing on a variety of issues. Nevertheless, despite the difficulties of many farmers to orient their business towards potential customers, the contribution of the marketing literature has been moderate. PURPOSE This dissertation builds upon studies which advocate the necessity of farm tourism to innovate itself according to the increasingly demanding needs of customers. Henceforth, the purpose of this dissertation is to critically evaluate the level of professionalism reached in the farm tourism market within a marketing approach. METHODOLOGY This dissertation is a cross-country perspective incorporating the marketing of farm tourism studied in Germany and Italy. Hence, the marketing channels of this tourist sector are examined both from the supply and the demand side by means of five exploratory studies. The data collection has been conducted in the timeframe of 2006 to 2009 in manifold ways (online survey, catalogues of industry associations, face-to-face interviews, etc.) according to the purpose of the research of each study project. The data have been analyzed using multivariate statistical analysis. FINDINGS A comprehensive literature review provides the state of the art of the main differences and similarities of farm tourism in the two countries of study. The main findings contained in the empirical chapters provide insights on many aspects of agritourism including how the expectations of farm operators and customers differ, which development scenarios of farm tourism are more likely to meet individuals’ needs, how new technologies can impact the demand for farm tourism, etc. ORIGINALITY/VALUE The value of this study is in the investigation of the process by which farmers’ participation in the development of this sector intersects with consumer consumption patterns. Focusing on this process should allow farm operators and others including related businesses to more efficiently allocate resources.

Nuove tecniche per l'allevamento massale di Ditteri del genere Coenosia Meigen

The species of the genus Coenosia Meigen are polyphagous predators both in the larval and in the adult stage. In Europe five Coenosia species of the ‘tigrina group’ are naturally present in greenhouses, where they can establish for long periods. As their wide preys range includes important pests of protected crops, as Aleyrodidae, Sciaridae and Agromyzidae, Coenosia species are considered promising potential biological control agents. A method for rearing Coenosia species in vivo was developed for the first time in 1993 in Germany, where C. attenuata, C. strigipes and C. humilis were bred on Bradysia paupera (Diptera Sciaridae), reared on Fusarium spp. cultivated on wood fibre. Although this method was partially simplified afterwards, it is still too complex and expensive for a mass production. This research aimed at simplifying this rearing procedure and making it cheaper, in the perspective of an eventual mass production. Studies on potential preys were conducted, to determine their suitability for C. attenuata larvae and adults and to develop rearing methods. Biology and rearing methods of Bradysia paupera Tuomikoski, Scatella stagnalis Fallén and Drosophila melanogaster Meigen (Diptera: Sciaridae, Ephydridae, Drosophilidae) were compared. B. paupera resulted the most suitable prey for rearing C. attenuata in vivo. The Sciarid fly was effectively reared on damp coconut fibre with fresh Agaricus bisporus (J.E. Lange) Pilát, thus simplifying the existing method. After preliminary trials with different potential preys, attempts to rear C. attenuata in vivo on B. paupera and D. melanogaster were made. The best results were obtained with B. paupera, reared on coconut fibre and A. bisporus, but the method needs further improvement. Trials of in vitro rearing of C. attenuata were also made: as no specific diet for Coenosia species is reported in literature, different potentially suitable media were tested. Among these, a specific diet for Diptera Tachinidae resulted a good starting point for further studies and improvements. The biology of C. attenuata adults captured in greenhouses was also studied, by observing both groups and isolated individuals. Data on lifespan, daily number of preys per adult, daily number of laid eggs and hatching rate were recorded, and the effects of different foods on these parameters were analyzed. The following foods were compared: D. melanogaster adults only, as preys for C. attenuata; D. melanogaster adults and a water-honey solution; the water-honey solution only. Honey resulted an effective food integration for C. attenuata, increasing lifespan and the number of egg laying females. It is possible that in greenhouses Coenosia adults complete the preys diet with nectar and/or honeydew. Moreover, the integration with honey reduced the daily preys consumption. This may allow to prevent cannibalism among Coenosia adults in the rearing conditions, where high population densities are required. A survey of the Coenosia species naturally present in Lombardy greenhouses was conducted. The species C. attenuata, C. strigipes, C. tigrina and C. atra were detected. C. attenuata resulted the most common, recorded in most greenhouses and for consecutive years. Besides, the presence of potential preys, weeds and the crops were recorded in each greenhouse. Nevertheless, it is difficult to determine the relation between these parameters and the presence of Coenosia species.

La lunga storia dell'idrovia Padova - Venezia

The present dissertation focuses on an unfinished project for the construction of an inland waterway between Padua and Venice, in northern Italy. The history of this channel is analysed in the context of the general debate for the development of a waterway network in the Padanian plain. The project of reconstructing and enlarging the existing ancient channels for the development of a modern river transport system was born at the beginning of the 20th century as an attempt to withstand the railway’s concurrency. The main project aimed at transforming the Po river and other small rivers and channels in a big waterway for the connection of the most important northern industrial cities with Venice’s harbour and the Adriatic sea. Even if the idea of restoring the historical channel between Padua and Venice arose at the end of the First World War, it was only during the years 50s that a new project was conceived and the waterway was included in a global project for the construction of a whole new channel from Venice to Milan. The new project, strongly supported by the local Christian Democratic Party, was managed for more than twenty years causing a huge expenditure of money. After a great investment by both the central State and the local bodies (more than 100 millions euro) the project was finally abandoned. This research reconstructs the historical process and the economical motivations that sustained that project until its failure. Moreover, with the aim of understanding the reasons and the differences of such a failure, the history of inland waterway transport in Italy is compared with contemporary developments in Germany.

I concerti per due violini di Vivaldi (con edizione di RV 513, 521, 528, 764 e ricostruzione di RV 520, 526)

In the whole of Europe the most important composer of concertos for two violins is indubitably Vivaldi (1678-1741), who produced almost thirty works of this type during almost the full length of his creative career. The dissertation examines this particular side of Vivaldi’s activity, starting with an examination of the concerto in Rome, Bologna, and Venice at the turn of the seventeenth and eighteenth centuries. The aspects investigated include the ‘conceptual’ origins of the double concerto for two violins in Vivaldi, the nature, distribution and interrelationship of their sources (particular attention being given to compositional revisions in the autograph manuscripts) and an analysis of the works themselves that takes in form, tonal structure, technical-instrumental character and performance practice. The concertos that have come down in particularly problematic non-autograph sources are discussed in detail and presented in critical editions. A reconstruction is offered of the two works (RV 520 and 526) that have survived only in incomplete form, lacking the part of the first soloist. The concertos for two violins composed in Germany by Telemann and J. S. Bach, the contemporaries of Vivaldi who paid greatest attention to the double concerto genre, are then described and analysed. The thesis ends with a complete list of modern editions of Vivaldi’s concertos for two violins and a select discography.

Il giudice tributario come giudice europeo

Questo lavoro, tramite un'analisi attenta ed accurata dello sviluppo delle pronunce della Corte di Giustizia in materia tributaria, ha lo scopo di mettere in evidenza i canoni interpretativi utilizzati dalla Corte, tenendo presente gli effetti che tali pronunce hanno prodotto nei singoli stati ed in particolare sul ruolo del giudice tributario come giudice europeo. Assistiamo infatti oggi ad una vera e propria europeizzazione della produzione giuridica in grado di aprire nuovi spiragli alla tutela del cittadino anche nei confronti dell'amministrazione finanziaria. L'interazione, per molti aspetti problematica, tra gli organi di giustizia tributaria dei singoli ordinamenti ed il giudice comunitario sono diventate vera e propria fucina di un diritto tributario europeo, nell'ambito del quale a svolgere un ruolo di estrema rilevanza è il giudice interno. Le sentenze del giudice tributario nazionale infatti rappresentano lo strumento più efficace di chiarificazione del diritto comunitario. Il presente lavoro si propone quindi di esaminare nel dettaglio il rapporto complementare e funzionalista che si estrinseca nella peculiare funzione attribuita al giudice tributario nazionale che gli fa assumere le vesti di "giudice europeo" nonché la funzione attribuita alla Corte di Giustizia che assume i caratteri sempre più marcati di "giudice tributario sovranazionale". Partendo dalla disamina delle figure dei giudici tributari di Germania, Francia ed Italia, si passerà poi ad evidenziare i ruoli che hanno avuto le Corti nazionali nell'applicazione del diritto comunitario, evidenziando come nei vari casi le sentenze si sono affiancate alla preminenza gerarchica della norma europea.
