This study aims to investigate the efficacy of the supply network approach in bolstering supply chain resilience amidst escalating global uncertainty. With enterprises worldwide facing increasing threats that disrupt supply chains, this research explores how firms enhance supply network resilience during crises.

Using a multi-case study design, this research thoroughly examines interactions within firms’ supply networks to uncover new insights on supply network approach and how firms enhance supply network resilience against global uncertainty. The selection of cases was methodologically aligned to represent diverse industries and geographical locations to ensure a comprehensive analysis.

This study’s findings reveal how firms develop supply network resilience during global crises. The supply network perspective provides a deeper understanding of how firms manage supply chain interactions, interdependencies and strategic positions to survive and thrive during crises. The conceptual framework developed here provides insights that can foster improved coordination and facilitate effective temporary organising. The framework highlights the need for firms to proactively seize opportunities and mitigate risks within their global supply chains during crises to boost overall resilience.

Offering novel insights into the domain of supply chain networks, this study underscores novel perspectives of the supply network approach when firms develop supply chain resilience during global crises. Highlighting the adaptive responses of firms that integrate these approaches enriches the understanding of strategic manoeuvres firms can use to navigate global uncertainty and secure supply chain continuity.

Limiting the use of antibiotics in food animals is a cornerstone of contemporary EU policy. Despite that marketing of antibiotics for growth promotion and nutrition has been banned since 2006, the use is still high and varied. This paper aims to investigate the forces behind the different usage patterns in Italy, with one of the EU’s most extensive use of antibiotics in animals, versus Sweden, with the union’s most restricted use, including how these usage patterns are related to EU and national policies.

The industrial network approach/the 4R resources interaction model is adopted to investigate the major forces behind the different antibiotic usage patterns. Furthermore, the study relies on the notion of three main characteristics related to the use of a resource activated in several user settings (Håkansson and Waluszewski, 2008, pp. 20–22). The paper investigates the Swedish and the Italian using settings, with a minimised, respectively, extensive usage of antibiotics. The study is exploratory in nature and based on qualitative data collected through a combination of primary and secondary sources.

The paper underlines the importance of integrating forces for policy to succeed in attempts to reduce the use of a particular resource. It reveals that Sweden’s radically reduced use was based on great awareness, close interactions between animal-based food producers and policy – and that integrating forces were supported by an era of state-protected food production, with promising ability to distribute the cost of change. The Italian characteristics hindering the integration of forces mounting for reduced use were restricted awareness, top-down business and policy interactions – and a great awareness about the difficulties of distributing the cost of change.

The study deals with the analysis of forces affecting the different usage of antibiotics within two EU settings. The investigation, based on the industrial network approach’s notion of connectivity of economic resources, that is, of exchange having a content and substance beyond discrete transactions, reveals how indirect related contextual forces, neglected by policy, have an important influence on the ability to achieve change, in this case of antibiotics usage patterns.

Beginning with a historical outline and the definition of tourism as a privileged opportunity for physical and spiritual renewal, the author deals with the question of how young people put themselves in touch with religion and spirituality. After 2012, Catholic pastoral has changed: not only devotional attention to the pilgrimages but also an overview of the resources constituted by sacred places as a tool for socioeconomic and cultural development of destinations. Religious tourism means an appropriate moment to let the body relax and to nourish the spirit: from this approach, the author shows examples of ‘religious light tourism’ in Europe founded on an ecumenical approach and on sustainability. The effects are positive: for the offer, new jobs (guides, resorts, enogastronomic and folkloristic services); for the demand, a new way to preserve the beauty of creation for future generations, by offering emotional and not massive travels: Caminos, trekking and slow paths, in order to know local traditions and nature. Therefore, ‘religious light tourism’ is a champion of sustainability and responsible tourism because religious tourism is, usually, less affected by season's trends, social and economic crisis (but not in the present COVID-19!).

The purpose of this paper is to discuss the dynamics of the evolution of damage to the residential buildings within the city walls of Norcia during the six-month seismic swarm that hit Central Italy in the period 24th August 2016 to end of January 2019. This is accomplished by comparing the damage recorded by the Italian Civil Protection usability form (AEDES form) during this period after each event.

First, these outputs are compared with a qualitative assessment conducted by means of omnidirectional camera (ODC) imagery collected on site by the authors, to explore the ability of this technology to support post-earthquake damage assessment. The damage level attributed with these two techniques is then further compared with the output of the analytical vulnerability assessment method FaMIVE, which allows to correlate damage to vulnerability. Specifically, the objective is to investigate the efficacy and performance of historic and recent strengthening interventions.

Results show that there is a good correspondence between AeDES and ODC assessments for low to medium damage grades (DG). Discrepancies in higher DGs are discussed in light of the different levels of information that can be recorded by using the two tools. The efficacy of strengthening is also well captured by the FaMIVE method. The procedure estimates a decrease of almost 40, 25 and 20 per cent of the total number of buildings failing out-of-plane, respectively, for the three seismic events considered, when restraining elements are in action.

The analysis conducted in this work make use of deterministic values of Norcia’s masonry fabric characteristics that have been found in literature, thus implying that neither the probabilistic aspects nor the related uncertainties have been properly investigated and addressed. However, this limitation is to be considered within the more general context of the legislation for the preservation of historic buildings which limits substantially any type of semi-destructive tests, hence limiting the reliability of the values available in literature. This in turn affects the decisions informing the design and implementation of strengthening interventions which can be confidently considered reliable and effective.

The paper addresses for the first time a systematic investigation of damage progression in historic masonry structures, part of urban aggregates in heritage cities. The current urban fabric is discussed in view of historic building codes as the basis for determining the present seismic vulnerability of the historic city centre of Norcia. The study provides new data sets for the city of Norcia and develops a statistical correlation between cumulative damage and analytical vulnerability functions for heritage buildings exposed to a swarm of earthquakes. The analytical assessment of the effect of historic strengthening is totally novel.

The purpose of this paper is to explore a multi-innovation with forgetting factor-based EKF-SLAM (FMI-EKF-SLAM) algorithm to solve the error increasing problem, caused by the Extended Kalman filtering (EKF) violating the local linear assumption in simultaneous localization and mapping (SLAM) for mobile robots because of strong nonlinearity.

A multi-innovation with forgetting factor-based EKF-SLAM (FMI-EKF-SLAM) algorithm is investigated. At each filtering step, the FMI-EKF-SLAM algorithm expands the single innovation at current step to an extended multi-innovation containing current and previous steps and introduces the forgetting factor to reduce the effect of old innovations.

The simulation results show that the explored FMI-EKF-SLAM method reduces the state estimation errors, obtains the ideal filtering effect and achieves higher accuracy in positioning and mapping.

The method proposed in this paper improves the positioning accuracy of SLAM and improves the EKF, so that the EKF has higher accuracy and wider application range.
