Abstract The current national and regional economical conjuncture in many countries, requires a sustainable management of different urban infrastructures, including road signs. From the set of possible solutions to improve the existing infrastructure’s management, analysis and spatial representation, Geographic Information Systems (GIS) have proved to be an essential tool for the functional competencies of local administration (municipalities), managers of municipal road networks. This study presents a framework of existing national regulations on road signs, as well as the shortcomings in the definition of methodologies for GIS-based management systems implementation. The paper continues with the critical assumptions considered in their definition and the municipalities specific competences needed for their implementation. A low-cost methodology is proposed and applied to a case study in a small Portuguese village: Belmonte. The results have shown the potential of these low-cost systems, revealing relevant time and economical gains, providing municipalities with fundamental information for the definition of realistic and well-founded strategic plans and budgets, and allowing better information to their citizens. The gathered information can help in inventory, inspections, maintenance and replacement allowing detailed reports and geo-referenced electronic database and maps of a municipality's road signs at reasonable costs. These maps and reports are the starting point to forecast the projected lifespan of the municipality's signage allowing more accurate project sign management budgets for future years. Aspects that need further development in order to improve the proposed system are also addressed.

In this paper, a case study is used to evaluate the business process characterizing modeling (BPCM) language. The BPCM-framework is meant to guide both business stakeholders and model developers during model-based development. The focus of the approach is the use of BPCM as a starting point for capturing process knowledge when planning and developing information system support. Based on information within the BPCM models, goal models and process models can be developed and used for further development of the BPCM model. The approach in this paper is evaluated using a case study related to the arrangement of a conference series. Through the case study, the authors have confirmed the potential usability and usefulness of BPCM for early stage knowledge capture, getting input for further improvement of the approach.

Abstract The aim of this paper is to present a further development of the Corbelling Theory [1] for assessing the structural safety of “false domes” constructions like Trulli, and more generally for corbelled domes. In particular, it is well-known that a corbelled dome of a Trullo is a layered thick shell and that only the thin inner layer (candela) has a structural role. The proposed procedure extends the capabilities of the approach proposed in [2] to more general load conditions, including the infill. The effectiveness of the proposed approach is discussed through the analysis of a paradigmatic case study of a Trullo located in Alberobello. Since the geometry of the construction plays a fundamental role in the structural behavior, the starting point of the analysis was an accurate 3D-laser scanner survey of the dome. The obtained results give some interesting insights about the role of the infill load on the equilibrium of such kind of corbelled domes.

AbstractGenotype by Environment interaction (G × E) studies have focused mainly on estimating genetic parameters over a limited number of experimental trials. However, recent Geographic Information System (GIS) techniques have opened new frontiers for understanding and dealing with G × E. These advances allow increasing selection accuracy across all sites of interest, including those where experimental trials have not yet been deployed. Here, we introduce the term Enviromics under an envirotypic-assisted breeding framework and propose the GIS-GE method, i.e. a geospatial tool to maximize genetic gains by predicting the phenotypic performance of unobserved genotypes using “enviromic markers”. In summary, a particular site represents a set of envirotypes, each one representing a set of environmental factors that interact with the genetic background of genotypes, thus resulting in informative re-rankings to make decisions over different environments. Based on a simulated case study, we show that GIS-GE allows accurate (i) matching of genotypes to their most appropriate sites; (ii) definition of breeding areas that have high genetic correlation to ensure selection gains across environments; and (iii) indication of the best sites to carry out experiments for further analysis based on environments that maximize heritability. Envirotyping techniques provide a new class of markers for genetic studies, which are inexpensive, increasingly available and transferable across species. We envision a promising future for the integration of the Enviromics approach into breeding when coupled with next-generation genotyping/phenotyping and powerful statistical modeling of genetic diversity. Environmental scenarios can also be improved using information from strategic plans for biodiversity and genetic resources management, especially in the current perspective of dynamic climate change.Key messageWe propose the application of Enviromics to breeding practice, by which the similarity among sites assessed on an “omics” scale of environmental attributes drives the prediction of unobserved genotypes.

The Internet of Things and its technologies have evolved quickly in recent years. It became an umbrella term for various technologies, embedded devices, smart objects, and web services. Although it has gained maturity, there is still no clear or common definition of references for creating WSN-based IoT systems. In the awareness that creating an omniscient and ideal architecture that can suit all design requirements is not feasible, modular and scalable architecture that supports adding or subtracting components to fit a lot of requirements of various use cases should be provided as a starting point. This chapter discusses such an architecture and reference implementation. The architecture should cover multiple layers, including the cloud, the gateway, and the edges of the target system, which allows monitoring the environment, managing the data, programming the edge nodes and networking model to establish communication between horizontal and vertical embedded devices. In order to exemplify the proposed architecture and reference implementation, a smart irrigation case study is used.

Purpose. The attempt to create a definition of the shock tourism as a type of dark tourism. The phenomenon of spontaneous travels to sites of disasters was first described from the anthropological perspective by Chris Rojek in 1993. He used the term black spots, referring to places that became travel destinations in reaction to current media coverage (spotlights). In Polish research we hitherto lack the translation of this term, as well as explicit descriptions of travels which are the immediate result of current media coverage. The proposed definition of shock tourism will be presented not only as a kind of „sensation tourism”. The visitors, through their presence, not only influence the shape of memory sites but they also take part in creating the memory of tragic events. The example of New York’s Ground Zero shows us how much, over the course of recent years, not only the physical space of the site, but also its symbolic dimensions have changed. The narration of 11th September National Museum, the 9/11 Memorial Site and the work of non-profit 9/11 Tribute Center contribute to changing the perception of „shock sites” from lieux de l’imagination to lieux de mémoire. Method. Fieldwork, participant observation (an analysis of narratives of 9/11 National Museum and Memory Site; observation of tourists’ and tour guides behaviour). Findings. An analysis of narratives of 9/11 National Museum and Memori Site, as well as the activity of 9/11 Tribute Center became a starting point to further considerations on the role of tourists in creating postmodern lieux de mémoire. Research and conclusions limitations. Limited time of fieldwork (10 days). Originality. The paper concerns postmodern phenomenon of the evolution od post-disaster sites into the memorylands, according to Sharon Macdonald’s concept. The framework of shock tourism opens new horizons and research perspectives of this process. Type of paper. Theoretical paper based on case study of 9/11.

Abstract This research aims to answer the question if e-commerce favoured in a special way the growth of low-cost carriers within the civil aviation market. After defining low-cost and traditional carriers’ business models, data on transported passengers were collected for three countries (Italy, Germany and Spain) and confronted with the number of e-consumers. Despite a significant correlation in all the three markets, only in Italy our hypothesis has been supported by Granger causality, and the regression analysis allows to forecast a future characterized by a growing dominance of LCCs. Although the definition of an econometric model will require further studies, the distinctive features of the Italian market might represent a starting point for future research on the complex relationship between e-commerce and air transport.

This study explores the idea of a significant business, framing it through the key concepts that define it and illustrating it through a case study that narrates the evolution of a century-old company. Born as an intellectual response to the economic and financial crisis of 2008, the significant business is conceived as an entity capable of enduring over time through the creation of value and its distribution within the community in which it operates. The significant business should be also aware of its own identity and of the need to innovate itself over time considering the synergies and the collaborations that the territory offers, to continue to create wealth. This contribution is part of a series of works that, resulting from numerous action-research projects coordinated by Professor Carlo Bagnoli, have seen as protagonists the companies and their strategic innovation. The starting point of many of these projects is the Manifesto of the Significant Company (Bagnoli et al. 2015), which aims at imagining a business model able to explore and innovate the company to increase its competitiveness, and also to restore meaning to the company itself, through the definition of its own identity. Contributing to previous works, this book explores the idea of significant enterprise by adopting a business and a historical perspective. The first part of the book deals with the business perspective, to introduce the value model commonly used in action research studies undertaken by the spin-off Strategy Innovation of Ca’ Foscari University of Venice, and to describe the specific model of a significant business. The second part of the book narrates the story of a centuries-long business, Barovier&Toso, exploring its evolutions. Focusing on the different perspectives that shaped the key concepts and narrating the path followed by a centenary company, this work hopes to shed further light on this fascinating theme together with the reader.

AbstractIn the manufacturing industry, the smart factory is considered the final stage of the Fourth Industrial Revolution. Manufacturing companies are pursuing breakthroughs by introducing various advanced technologies to ensure their competitiveness. However, it is difficult for small and medium-sized enterprises (SMEs) to adopt smart-factory technologies, owing to financial and technical burdens. This paper proposes a smart factory that can be applied technically and strategically to the introduction of a smart factory for SMEs. The concept of an ‘appropriate smart factory’ involves applying appropriate measures in terms of cost and scale with consideration of the situations faced by SMEs. The goal is to build a smart factory that has necessary functions (Essential) but can be easily operated (Simple) at a low cost (Affordable) and has compatibility (Interoperable). This paper presents technical application measures such as appropriate smart sensors, appropriate IoT (Internet of Things), and small data processing, along with the definition of an appropriate smart factory. In addition, a case study was examined where the quality inspection equipment for garment manufacturing SMEs was developed by applying the appropriate smart factory concept.

Abstract. The paper aims to investigate the potential inherent in a FOSS (Free and Open Source Software) approach for the 4D BIM modelling using Freecad. In order to reach this goal it shows a comparison of Freecad features with those of commercial software, considering the evaluation of the effective application of this Open Source software in the professional environment, and highlighting the progress in the FOSS BIM area, that still represents an unexplored study field if compared to the vast publications related to BIM modelling that occurred in the last two decades. To this end, the study has been carried out on a singular case study, a steel canopy which has been designed for the urban renewal of a public space in Teramo. Despite its size, the canopy required the definition of complex details. Its structural system has addressed the study to compare Freecad with some software dedicated to steel structures or particularly suitable for the modelling of this specific structural typology: Tekla Structures and Sketchup. Starting from a concise historical reconstruction of the FOSS spread, the paper introduces a brief overview of the potential of Freecad in terms of BIM modelling - also proposing an operational modality to facilitate the drawing of BIM elements within the software - and finally reaching to the examination of three simulations which has been carried. This comparison can be useful to establish the current state of development of Freecad in the field of 4D BIM.
