The Typicality of the Agri-Food Product Driver of the Enhancement of Destination Tourism The Apulian Case History

Typical products are becoming more and more an element of differentiation and qualification of entire territories, becoming one of their resources or, in some cases, the main resource and the real tourist attraction factor of the tourist resorts that direct their own promotion strategies of the territory to the new segments of tourist demand (tourists of taste or gastronauts, green tourists). In this sense, it becomes essential to activate synergies and commercial relations with the local economic system (for example with catering, trade, crafts) in order to actively consolidate the ancient territorial link, strengthening its image among consumers: thus, effectively serving as a promotional tool and enjoying the benefits derived from such approaches. Objective of the paper: "Indeterminacy" is the term that characterizes the concept of typicality of the agri-food product and that arises from the low level of information either of consumers and producers of agricultural raw materials and other operators in the supply chain. This work aims to analyze how much the knowledge and impact of the typical Apulian agri-food product affects the choice of the tourist destination. Methodology: The work is based on the analysis of data resulting from a survey in 2020 aimed at potential buyers of the agri-food product aimed at understanding the impact of the typical Apulian agri-food product in the choice of touristdestination. Results: The analysis carried out highlighted how the knowledge, awareness and enhancement of typical products represent a strong attractive lever for tourist flows, with a view to choosing the potential final destination. From the testimonies of the users and internal stakeholders it was clear that the typicality has not affected the value of the destination, which remains primary in the purchase intentions of potential customers, but has triggered a climb in the hierarchy of preferences of those who intend to live an experience Italian or foreign tourists, in fact, evaluate the offer enriched by the multiple nuances of the territorial tradition within a specific tourist route. Research limits: This work is intrinsically limited by the strictly qualitative nature of the survey, as well as by the analysis of a single case study. Originality: The originality of the study lies in the contribution it intends to provide to the advancement of research focused on the analysis based on the connection among the territory, typical products and tourist flows

Three-dimensional modelling of scattering loss in InGaAsP/InP and silica-on-silicon bent waveguides

A three-dimensional (3D) method for the estimation of scattering loss due to sidewalls roughness in bent optical waveguides is proposed and validated. The approach, based on Volume Current Method (VCM), has been pointed out to accurately calculate the scattering loss as dependent on curvature radius and wavelength. An exponential model has been employed to analytically describe the sidewalls roughness and a 3D mode solver based on mode-matching method has been used to calculate optical field distribution in the bent waveguide cross-section. Scattering loss suffered by two low index contrast waveguides has been investigated by the developed algorithm. For a buried InGaAsP/InP waveguide and a 6 μm x 6 μm Silica-on-Silicon guiding structure scattering loss dependence on bending radius, wavelength, roughness, correlation length and standard deviation has been investigated and discussed. Because of the different index contrast values, InGaAsP/InP waveguide exhibits a scattering loss which is quite six times larger than in Silica-on-Silicon. For both guiding structures, quasi-TM mode shows a larger scattering loss than quasi-TE one

Quality factor and finesse optimization in buried InGaAsP/InP ring resonators

Quality factor and finesse of buried In1-xGaxAsyP1-y / InP ring resonators have been optimized in this paper by a very general modelling technique. Limiting effect of propagation loss within the ring has been investigated using a three-dimensional (3D) highly accurate complex mode solver based on mode matching method to analyze bending loss dependence on ring radius and wavelength. Coupling between straight input/output (I/O) bus waveguides and ring resonator has been studied by 3D Beam Propagation Method (BPM), deriving coupling loss and coupling coefficient for a large range of ring radius and bus waveguides-ring distance values (for both polarizations). Ring resonator has been modelled by the transfer-matrix approach, while finesse and quality factor dependence on radius has been estimated for two resonator architectures (including one or two I/O bus waveguides) and for quasi-TE and quasi-TM modes. Guiding structure has been optimized to enhance resonator performance. The modelling approach has been validated by comparing results obtained by our algorithm with experimental data reported in literature. Influence of rejection (at resonance wavelength) at through port on quality factor and finesse has been widely discussed. A quality factor larger than 8 x 105 has been predicted for the ring resonator employing only one I/O bus waveguide and having a radius of 400 μm. This resonator exhibits a rejection of -8 dB at through port
