Blockchain acceptance and adoption in the tourism industry
Tourism has always been characterized by extensive innovativeness (from theme parks and cultural&gourmet tours till a deeper service integration). Today, digital solutions represent an opportunity to expand and innovate the range of services offered. Focusing on blockchain as an emerging technological solution, the paper investigates how expert and practitioners perceive the potentialities and limitations of its adoption in tourism.To capture the attitudes expressed in the field, we analyze the ongoing discussions on a major social network: Twitter.Through a social network analysis of the flow of tweetsconducted overthree months, we map the current perceptions towards blockchain. Specifically, we contribute to the literature on technology acceptance and adoption by intercepting the current perceptions in the tourism industry.This paper shows how experts and practitioners are envisioning the possibilities that blockchain shape future services in the tourism sector. Our study is based on an extensive literature review and a social network analysis of a Twitter-database. This allows us to investigate the current sentiment towards blockchain, and also to envision future directions of a promising and yet under analyzed technology
Grapevine rupestris stem pitting-associated virus is linked with grapevine vein necrosis
Vein necrosis (VN), a virus-like disease latent in all European grapevine cultivars and in most American rootstock species and hybrids, induces necrosis of the veinlets of its specific indicator Vitis rupestris x Vitis berlandieri 110 R at the abaxial side of the leaf blade. VN is very common in southern Italy, e.g. 109 out of 218 of the putative grapevine clones selected during sanitary improvement programmes in the last few years indexed positive in 110 R. As assessed by ELISA, the same vines had a very low rate of infection (< 4 %) by major detrimental viruses (GFLV, GVA, GVB, GLRaV-1, GLRaV-2, GLRaV-3, GLRaV-7, GFkV) commonly looked for during selection. When the VN-positive 110 R indicators were checked by PCR and Western blot for the presence of Grapevine rupestris stem pittingassociated virus (GRSPaV) a strikingly high association (98 %) was observed between this virus and VN symptoms. Likewise, all 72 mother plants of Vitis rupestris used as indicators in indexing trials and recently discovered to be infected by GRSPaV, induced VN reactions after grafting onto 110 R. By contrast, no VN reactions developed in 110 R top-grafted on a single GRSPaV-free V. rupestris. Moreover, GRSPaV was consistently detected in the symptomatic lower leaves of the shoots of infected 110 R vines, but not in the symptomless upper leaves of the same shoots. These findings strongly suggest that GRSPaV is involved in the aetiology of VN
New insight into the identity of italian grapevine varieties: The case study of calabrian germplasm
Calabria is a region located in Southern Italy and it is characterized by a long tradition of viticulture practices and favorable pedoclimatic conditions for grapevine cultivation. Nevertheless, less than 2% of cultivated land is dedicated to grapevine growing in Calabria. The characterization of local grapevine accessions is crucial to valorize the local and peculiar Italian products and boost the Calabrian winemaking sector. With this purpose, we performed a deep characterization of two widespread Calabrian grapevine varieties—Magliocco Dolce and Brettio Nero, of which very little is known. In particular, a genetic and morphological analysis, a berry physico-chemical and polyphenolic compositions assessment, and oenological evaluation of monovarietal wines were carried out. Our results allowed us to demonstrate that Magliocco Dolce and Brettio Nero are unique and distinct varieties with peculiar morphological and chemical characteristics and show the suitability of these two varieties in high-quality wine production. Moreover, the obtained molecular profiles will be useful for authentication and traceability purposes
Burden of disease, healthcare pathways and costs of cardiovascular high-risk patients with type 2 diabetes: a real world analysis:
Objective: To estimate the burden of disease and to describe healthcare pathways and costs of type-2diabetes (DMT2) patients at high cardiovascular risk (HRCV). Methods: A real-world analysis was performed by using a subset of the AR-CO database, containing administrative health data of >4.3 million of inhabitants. A cohort of adult patients with DMT2 and HRCV was selected in 2013, and followed for 1 year. Through this period, information on antidiabetic and cardiovascular therapies, other co-treatments, hospitalisations, and outpatient services, was collected and analysed. The costs associated with each variable were assessed to estimate the integrated health care expenditure. Results: Overall, 7,167 patients with DMT2 and HRCV were identified, corresponding to 3.1% of all diabetic patients and 0.2% of adult population. During the 1-year follow-up, 90.1% of the cohort received at least a prescription of an antidiabetic drug, 98.0% of a cardiovascular medication and 95.9% used at least an outpatient service. 44.5% had an admission during the follow-up period, especially for cardiovascular events. The integrated cost analysis showed that the overall average cost for each subject was € 13,567. Hospitalisations generated 86.8% of this expenditure, followed by drugs (7.7%) and by outpatient services (5.5%). Conclusions: Although patients with DMT2 and HRCV represent a small percentage of the overall population with diabetes, they generate very high costs for National Healthcare System. These costs are mainly due to the hospitalisations, especially for cardiovascular events. New therapeutic strategies involving these patients should allow reduction of hospital admission, resulting in savings for National Healthcare System
