The purpose of this chapter is first to establish a state of the art about cargo tram, in order to understand its opportunities and constraints. In a second step, the aim is to add an often overlooked spatial dimension in the analysis, which may offer a renewed insight into the issue and extend the understanding of the potential use of urban light rail for freight.

The first step of the analysis is carried out through a study of the literature. In particular, the potential use of cargo tram for the various urban supply chains is evaluated. The aim is to establish a European state of the art on urban light rail use for freight. Then, to concretise these elements and to add an empirical geographical approach, the Brussels situation is studied in detail.

This combination of a theoretical analysis and a field approach of the case of Brussels allows us to lead an original study. Obstacles, opportunities and interest for the implementation of cargo trams are specified. In addition, the use of geographical approach gives a new point of view since most of the publications in this field are based on economic or technical approaches.

This study may help public and private actors involved in urban freight matters, as well as public transport companies, to better understand the issues related to cargo trams. In a context where this transport mode is promoted and discussed in a growing number of cities and urban supply chains, it is useful to get an objective synthesis and a prospective analysis on this topic. This research may also have social implications in the way it helps to define a more sustainable urban logistics.

The originality of this research is related to the combination of a theoretical and empirical approach, to the link that is made between urban supply chains and capabilities of cargo trams and finally to the prospective study on the Brussels case. Indeed, because of the novelty of the topic, there are very few studies, either ex-post or ex-ante.

How does context shape the way in which corporations contribute to or impede progress toward sustainable development goals (SDGs)? In this chapter, the author studies how the state as corporate owner and in its broader function in the institutional environment affects companies’ involvement in misbehaving practices related to human rights issues, with a focus on the banking industry. Based on a longitudinal analysis of 178 banks over the cohort 1996–2018, the results show that state-owned banks, as well as those from institutionally weak environments, are more involved in business-related misbehaving practices. Moreover, in a strong institutional environment, state-owned banks are more involved in corporate misbehavior than non-state-owned banks. These results contribute to the literature on corporate misbehavior, focusing on the state’s role in preventing or facilitating banks’ involvement in misbehaving practices. The author concludes by discussing the findings’ implications and providing suggestions for future research.

This paper aims to investigate the need for active boundary conditions during fire testing of structural elements, review existing studies on hybrid fire testing (HFT), a technique that would ensure updating of boundary conditions during a fire test, and propose a compensation scheme to mitigate instabilities in the hybrid testing procedure.

The paper focuses on structural steel columns and starts with a detailed literature review of steel column fire tests in the past few decades with varying axial and rotational end restraints. The review is followed with new results from comparative numerical analyses of structural steel columns with various end constraints. HFT is then discussed as a potential solution to be adapted for fire testing of structural elements. Challenges in contemporary HFT procedures are discussed, and application of stiffness updating approaches is demonstrated.

The reviewed studies indicate that axial and rotational restraints at the boundaries considerably influence the fire response of steel columns. Equivalent static spring technique for simulating effect of surrounding frame on an isolated column behavior does not depict accurate buckling and post-buckling response. Additionally, numerical models that simulate fire performance of a column situated in a full-frame do follow the trends observed in actual test results up until failure occurs, but these simulations do not necessarily capture post-failure performance accurately. HFT can be used to capture proper boundary conditions during testing of isolated elements, as well as correct failure modes. However, existing studies showed cases with instabilities during HFT. This paper demonstrates that a different stiffness updates calculated from the force-displacement response history of test specimen at elevated temperature can be used to resolve stability issues.

The paper has two contributions: it suggests that the provision of active boundary conditions is needed in structural fire testing, as equivalent static spring does not necessarily capture the effect of surrounding frame on an isolated element during a fire test, and it shows that force-displacement response history of test specimen during HFT can be used in the form of a stiffness update to ensure test stability.

Tourism is Mexico's largest source of foreign exchange, only surpassed by remittances and foreign direct investment, and is one of the most wealth-generating economic activities in the country. However, measures to mitigate the Covid-19 pandemic – such as the suspension of flights and strict restrictions on people's mobility – have caused great economic damage to the tourism industry, and with it, to large regions in the country. This chapter aims to determine the national and regional impacts of Covid-19 on Mexican tourism and analyze potential recovery scenarios. To this end, the study looks at tourism performance in Mexico in 2020 and compares it to the experience of the H1N1 influenza epidemic of 2009. The methodology uses a spatial econometric model to simulate potential impacts and prospective recovery scenarios. Finally, recommendations for tourism policy consider new trends in tourism, namely the rise in tourism advertising through digital platforms, the surge in domestic, rural and environmental tourism, and the development of a more informed, demanding and selective consumer.

It is no longer enough to have a technology base to meet customer needs. The competitiveness of the tourism sector is ensured through the innovation capacity that companies can achieve, either through innovation associated with services or through services. The relationship between tourism innovation and business competitiveness in the tourism sector must consider emerging and innovative technologies that appear daily in society. In this context, the information systems applied to tourism must take into consideration the various sectors of activity: accommodation, travel agencies, restaurants and gastronomy, tourist entertainment, transport, among others. In addition to tourism management information system, it must integrate an innovation mechanism, which should be based on the definition of an appropriate business model. The business model that ensures innovation has to integrate design, production, service, and marketing through a new customer relationship, therefore technology must be able to meet the demands inherent in this new model. The purpose of this chapter is to investigate how the concept of Industry 4.0 can affect the development of tourism in Portugal. In this context, it is relevant for tourism that all companies consider the technological drivers of change associated with the concept of Industry 4.0, constituting a technological basis for leveraging tourism companies to a technological environment called ‘Tourism 4.0’.

This paper is mainly aimed at the structural performance of compound cold-formed galvanised steel beams under fire conditions based on the results of a large programme of experimental tests and numerical simulations. The main objective of this research was to assess the critical temperature and time of the studied beams. Other important goals of this research work were to investigate the influence of the cross-sections (C, lipped-I, R and 2R beams) and, above all, of the axial restraint (0, 0.45, 3, 7.5, 15, 30, ∞ kN/mm) to the thermal elongation of the beam and the rotational restraint at beam supports (0, 15, 80, 150, 300, 1,200 and ∞ kN.m/rad) on the fire resistance of this kind of beams.

This paper still provides details of the simulation methodology for achieving numerical stability and faithful representation of detailed structural behaviour and compares the simulation and experimental results, including beam failure modes, measured beam axial forces and beam mid-span deflections.

Good agreement between Abaqus simulations and experimental observations confirms that the finite element models developed with the Abaqus/standard solver are suitable for predicting the structural fire behaviour of restrained cold-formed steel beams.

The results showed above all that the effect of the stiffness of the surrounding structure seems to decrease with the increasing slenderness of the beams.

The number of researches that evaluate how behavioural and personality issues affect consumers’ acceptance and perception of food is increasing. Thus, this study aimed to evaluate the effect of nutritional information and health claims related to soya and cashew nut beverages over consumers’ acceptance and perception regarding nutritional value and healthiness and to verify whether behavioural and personality issues affect such evaluation.

The samples were evaluated in two phases, with (blind phase) and without information (informed phase) about their composition, nutritional characteristics and functional claims related to some of their ingredients. The sensory evaluation data were analysed by means of the analysis of variance for repeated measures, applying 2 (information) × 2 (beverage) and generalised linear model to evaluate the effect of information over the acceptance averages, as well as over the perception of healthy food and nutritional value.

Information on composition, nutritional characteristics and functional claims related to the cashew nut and soya beverages did not influence flavour acceptance (p-value = 0.250) and overall impression (p-value = 0.316), but had a positive impact on consumers’ perception regarding healthiness (p-value < 0.001) and nutritious value (p-value < 0.001) of both beverages, the cashew nut beverage being perceived as more nutritious and healthier than the soya beverage. Consumers’ different characteristics with respect to their interest in healthy eating (high and low) and food neophobia (neophiliacs and neophobics) did not have any influence on the beverages’ acceptance, as well as on the perception of healthy food and nutritious value.

This work compares consumers’ acceptance and perception regarding nutritional value and healthiness with relation a totally unique product in the Brazilian market, and in the world, a new functional beverage made from cashew nuts, with a soya-milk beverage. Until this moment, there are no studies comparing consumer acceptance and perception of products based on hydrosoluble extract-base added with fruit juice which evaluate the influence of behavioural and personality characteristics of consumers in their perception and acceptance towards these products.

The impact of rapidly developing technologies on digitalization of production and planning has affected all sectors in a short period. This impact has led to both positive and negative outcomes. While it is helping the decision-makers to make better and more productive choices, it also can create a cluster of information and data that can put an undue burden on processes. Today, we call this Industry 4.0, which is defined as the use of digital technologies, based on data processing, the end-to-end connection of value chains, and ensuring data fluidity. Industry 4.0 consists of technologies such as cyber-physical systems, internet of things, cloud computing, big data and analysis, autonomous vehicles, and augmented reality. With the digitalization of the entire production and planning processes, data-based applications are made; thus it is important to protect data in this context, pointing to the critical importance of cybersecurity. Companies are constantly working on taking the necessary cybersecurity measures to prevent exposure to any cyberattacks. One of the biggest steps toward the development of production and planning is undoubtedly the integration and adaptation of blockchain technology. The use of blockchain technologies has been a major breakthrough for the sector in order to effectively meet customer needs, ensure information security, reduce costs, and achieve rapid growth. With digital transformation, production and planning must comply with the principle of transparency. In this context, integrating blockchain technologies into the production and planning ecology for data security will provide companies with a serious competitive advantage.
