The Assessment of the Tourism Potential of the Tagus International Nature Reserve Landscapes Using Methods Based on the Opinion of the Demand

There are different methodologies to assess landscape preferences, however there is no consensual methodology that can be replicated to identify their tourism potential. Recent studies have focused on agricultural landscape preferences due to their cultural characteristics. Although agricultural activity conflicts with the management models of natural protected areas, traditional models and sustainable practices reveal opportunities to boost tourism in this area, both for their aesthetic value, and for the opportunity to preserve biodiversity and maintain “lively landscapes”. The present study focuses on a double approach to collect data to measure the preferences for landscape typologies to realize outdoor/recreative activities in Tagus International Nature Reserve (TINR), among them, agricultural landscapes, such as the agro-silvopastural system “Dehesa/Montado” or olive grove. The preference of the landscapes were evaluated through photographs with pairwise comparison and without photographs observation, in which 174 respondents were consulted with. The different methodologies applied allowed for the extraction of different results, which led to the assumption that in fact there is no single methodology to assess preferences. However, the application of the analytic hierarchy process (AHP) methodology with photographical pairwise comparison allowed for the extraction of more robust results when considering attractions with tourism typologies, revealing that “Cultural tourism/Rural mixed” and “Agritourism” were the most valued. This information is pertinent to support TINR managers and local tourism promoters to plan and structure products and services based on button-up methodologies.

Biochemical Characterisation and Genetic Structure Provide Insight into the Diversity of the Mediterranean Tomato Ancient Varieties ‘San Marzano’ and ‘Re Fiascone’: New Resources for Breeding

Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops highly appreciated for the nutritional properties and content of beneficial compounds for human health. After its domestication, this crop has been spread throughout the world and found its secondary centre of diversification in the Mediterranean basin, where numerous landraces have been developed. Among these, ‘San Marzano’ is a famous and remunerative PDO variety for processing and fresh market consumption. ‘Re Fiascone’ is an ancient cultivar for which ongoing efforts aim to promote its diffusion and commercialisation. Both find their origin in the Campania region in Southern Italy where in the past decades, several accessions have been selected and handed down by farmers. This study reports a comprehensive assessment for morphological and biochemical traits of twenty-one accessions of the two landraces. Fruit morphology and content of sugars and flavonoids were the most discriminating parameters among cultivars. Among sugars and organic acids, fructose and citric acid were the most represented compounds, respectively. We found level of trans-lycopene and β-carotene up to 112.82 and 16.29 µg g−1 of fresh product, respectively, while ascorbic acid levels reached values up to 22.48 mg 100 g−1 of fresh weight. Molecular analysis has been performed using a double approach for microsatellite genotyping based on capillary electrophoresis and high-resolution melting. Results highlighted a separation of the accessions according to ‘Re Fiascone’ and ‘San Marzano’ identifying both unique and admixed accessions between the two groups. The study approach aims at the recovery and valorisation of local genetic resources, but also at the identification of traits of interest to transfer in breeding programs.

Designing industry 4.0 implementation from the initial background and context of companies

Industry 4.0 is a promising concept that allows industries to meet customers’ demands with flexible and resilient processes, and highly personalised products. This concept is made up of different dimensions. For a long time, innovative digital technology has been thought of as the only dimension to succeed in digital transformation projects. Other dimensions have been identified such as organisation, strategy, and human resources as key while rolling out digital technology in factories. From these findings, researchers have designed industry 4.0 theoretical models and then built readiness models that allow for analysing the gap between the company initial situation and the theoretical model. Nevertheless, this purely deductive approach does not take into consideration a company’s background and context, and eventually favours one single digital transformation model. This article aims at analysing four actual digital transformation projects and demonstrating that the digital transformation’s success or failure depends on the combination of two variables related to a company’s background and context. This research is based on a double approach: deductive and inductive. First, a literature review has been carried out to define industry 4.0 concept and its main dimensions and digital transformation success factors, as well as barriers, have been investigated. Second, a qualitative survey has been designed to study in-depth four actual industry digital transformation projects, their genesis as well as their execution, to analyse the key variables in succeeding or failing. 46 semi-structured interviews were carried out with projects’ members; interviews have been analysed with thematic content analysis. Then, each digital transformation project has been modelled regarding the key variables and analysed with regards to succeeding or failing. Investigated projects have consolidated the models of digital transformation. Finally, nine digital transformation types have been identified.

Discovering Geometric Inequalities: The Concourse of GeoGebra Discovery, Dynamic Coloring and Maple Tools

Recently developed GeoGebra tools for the automated deduction and discovery of geometric statements combine in a unique way computational (real and complex) algebraic geometry algorithms and graphic features for the introduction and visualization of geometric statements. In our paper we will explore the capabilities and limitations of these new tools, through the case study of a classic geometric inequality, showing how to overcome, by means of a double approach, the difficulties that might arise attempting to ‘discover’ it automatically. On the one hand, through the introduction of the dynamic color scanning method, which allows to visualize on GeoGebra the set of real solutions of a given equation and to shed light on its geometry. On the other hand, via a symbolic computation approach which currently requires the (tricky) use of a variety of real geometry concepts (determining the real roots of a bivariate polynomial p(x,y) by reducing it to a univariate case through discriminants and Sturm sequences, etc.), which leads to a complete resolution of the initial problem. As the algorithmic basis for both instruments (scanning, real solving) are already internally available in GeoGebra (e.g., via the Tarski package), we conclude proposing the development and merging of such features in the future progress of GeoGebra automated reasoning tools.

Beyond VIAF

This paper aims to investigate the reciprocal relationship between VIAF® and Wikidata and their possible roles in the semantic web environment. It deals with their data, their approach, their domain, and their stakeholders, with particular attention to identification as a fundamental goal of Universal Bibliographic Control. After examining interrelationships among VIAF, Wikidata, libraries and other GLAM institutions, a double approach is used to compare VIAF and Wikidata: first, a quantitative analysis of VIAF and Wikidata data on personal entities, presented in eight tables; and second, a qualitative comparison of several general characteristics, such as purpose, scope, organizational and theoretical approach, data harvesting and management (shown in table 9). Quantitative data and qualitative comparison show that VIAF and Wikidata are quite different in their purpose, scope, organizational and theoretical approach, data harvesting, and management. The study highlights the reciprocal role of VIAF and Wikidata and its helpfulness in the worldwide bibliographical context and in the semantic web environment and outlines new perspectives for research and cooperation.

À la rencontre de quelques avant-gardes choisies

This article undertakes a chosen journey through the various avant-garde manifestations that flourished since the end of the 19th century to the 60s. The reasons for their emergence and the excesses of their creations constitute the axes of this essay. Starting from the fanciful imaginary of Alfred Jarry incarnated by King Ubu, we will arrive at the sarcasms of Boris Vian singing La Java des bombes atomiques, to end with the convulsive beauty of Paul Éluard. By proclaiming themselves as the defenders of anti-art, they reject reason and rely on the absurd. They are characterized by chaos and imperfection, which leads them to sometimes commit destructive acts of mythical works whose sacred value is rooted in popular opinion. In turn, they advocate non-signification and contradiction as the guiding principles of their creation. Consistent with their aspirations for total independence and in whatever fields, including politics, they experience absolute creation freedom. Provocation, transgression, and subversion animate these texts eager to open new poetic horizons of writing and reading. From a double approach, theoretical and critical, we will try to forge a renewed vision of this disconcerting creation through contemporary expectations.

A Rare Case of De Garengeot Hernia: A Challenging Diagnosis and a New Approach

De Garengeot’s hernia is a rare entity in which the appendix is located within a femoral hernia and is almost invariably encountered incarcerated in an emergency setting. The clinical presentation is usually that of an incarcerated femoral hernia and is indistinguishable from other incarcerated femoral hernias. Here, we report on a 48-year-old female patient, known for a post-operative chronic seroma in the right groin since childhood, with a rare clinical presentation of a De Garengeot hernia. An abdominal CT-scan was performed, revealing an appendicitis with a stercolith in a femoral hernia. Generally, an inguinal approach alone (McVay procedure) is chosen and provides access for both appendectomy and hernia repair. In the absence of concomitant acute appendicitis, trans-abdominal pro-peritoneal laparoscopy (TAPP) could also be used as a single approach. In case of a rare presentation of acute appendicitis with probable contamination of the groin, we propose the double approach of laparoscopic appendectomy and hernia repair either with (if hernia sac is not opened during surgery) or without mesh. This approach is not yet described in the literature, and we think it the best technique to perform the appendectomy and hernia repair with little contamination of the groin.

Consumer appreciation of a shark-free eco-label for small pelagics

PurposeThe objective of this study is to assess if Italian fish consumers are sensible to shark protection and if they would contribute paying more for small pelagic fishes coming from fisheries that are certified as “shark-free”.Design/methodology/approachContingent valuation is used to estimate willingness to pay with a double approach, including a dichotomous choice and an open-ended question. Inconsistency between the two answers is allowed. This allows the correction of two sources of bias (i.e. preference uncertainty and anchoring effect) and has permitted that the two estimation methods converged to the same result.FindingsConsumers show interest for the “shark-free” label. Premium price is estimated at +26%. Variables affecting willingness to pay (WTP) in the sample are age, income, environmental attitude, knowledge of organic labels and frequency of small pelagics' consumption. Results need to be confirmed by a replication on a larger (probabilistic) sample and with a different distribution of bids.Originality/valueEcosystems provide different benefits to humankind, including non-use services, such as the satisfaction to know that a species is well conserved. Generally, appreciation is higher for what are considered charismatic species. In this paper, the authors investigate if sharks can be considered charismatic species despite their “bad reputation”. The interest in shark survival is measured indirectly using a “shark-free” label on a commercial species like anchovy, allowing to increase the value added of this low-price species.
