Abstract
A sheet metal forming simulation code has been developed, based on the explicit time integration scheme and Mindlin shell theory. It has been used for the analysis of a number of industrial parts. After recalling some modelling issues, this paper describes an industrial methodology based on the experience of those analyses. The aim of the methodology is to provide, at early design stage, information on the product formability with a workload and lead time adapted to the design delays. Concurrently 2D analyses, critical zones studies and coarse mesh global investigations can be used, with a flexible number of iterations, prior to full refined analyses of the forming process. The application of the methodology on several industrial examples is discussed.

Abstract
Purpose
At the inception of the Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM), logistics coordination was identified as important, both in practice and research, but few studies on the topic had been published. Ten years later, many, if not most, papers in the journal mention the topic. So the picture has changed, but to what extent? This paper discusses how coordination research has followed humanitarian logistics practice and vice versa.
Design/methodology/approach
The point of departure in the present article is the most salient topic from the study’s original papers (Jahre et al., 2009; Jahre and Jensen, 2010). The authors discuss how these topics have developed in research and practice. A recent literature review (Grange et al., 2020) enables us to pick relevant papers from JHLSCM and supplement them with more recent ones. The authors complement this approach with updated data on the cluster system, particularly the logistics cluster, to add insights from the empirical domain.
Findings
In practice, the cluster concept has developed from coordination within clusters in response to the inclusion of inter-cluster coordination in preparedness, and more recently a focus on localized preparedness. However, JHLSCM research does not appear to have kept pace, with a few notable exceptions. The majority of its papers still focus on response. To the extent that preparedness is covered, it is primarily done so at the global level.
Originality/value
The authors use a framework to discuss humanitarian logistics coordination research and identify important gaps. Based on developments in practice, the study’s key contribution is a revised model with suggestions for further research.

Abstract
This paper narrates the efforts made in Italy after the end of the Second World War to develop an economic and social model in between corporate capitalism and planned economy, on the one hand, and shareholder versus stakeholder capitalism on the other. The result was the institutional infrastructure that supported the Istituto per la Ricostruzione industriale (IRI), a state-owned public holding in charge of managing the funds of the so-called Marshall Plan. The history of IRI illustrates the importance of a pragmatic approach to dealing with institutional constraints and opportunities when faced with the need to reconstruct destroyed economies in a context of very fragmented societies such as those of post-war Italy. The result was the resistance to an acritical adoption of the corporate American model and the definition of a more balanced form of capitalism. In an era of new recovery plans, there is a lot we can learn from IRI’s history.

Abstract
Se vi è problema di difficile soluzione nel campo delle ricerche statistiche, che hanno per oggetto l'accertamento della consistenza e dello sviluppo dei fenomeni sociali ed economici, non vi è dubbio che quello riguardante il settore turistico presenta i maggiori ostacoli da superare. Essi riguardano anzitutto la possibilità di conseguire risultati di una certa esattezza e, in secondo luogo, di ottenere dati sufficientemente analittici in modo da poter studiare il turismo in tutti i suoi aspetti più interessanti.

Abstract
Purpose
This paper aims to highlight how big social data (BSD) and analytics exploitation may help destination management organisations (DMOs) to understand tourist behaviours and destination experiences and images. Gathering data from two different sources, Flickr and Twitter, textual and visual contents are used to perform different analytics tasks to generate insights on tourist behaviour and the affective aspects of the destination image.
Design/methodology/approach
This work adopts a method based on a multimodal approach on BSD and analytics, considering multiple BSD sources, different analytics techniques on heterogeneous data types, to obtain complementary results on the Salento region (Italy) case study.
Findings
Results show that the generated insights allow DMOs to acquire new knowledge about discovery of unknown clusters of points of interest, identify trends and seasonal patterns of tourist demand, monitor topic and sentiment and identify attractive places. DMOs can exploit insights to address its needs in terms of decision support for the management and development of the destination, the enhancement of destination attractiveness, the shaping of new marketing and communication strategies and the planning of tourist demand within the destination.
Originality/value
The originality of this work is in the use of BSD and analytics techniques for giving DMOs specific insights on a destination in a deep and wide fashion. Collected data are used with a multimodal analytic approach to build tourist characteristics, images, attitudes and preferred destination attributes, which represent for DMOs a unique mean for problem-solving, decision-making, innovation and prediction.

Abstract
This essay aims at retracing the intellectual and biographical events of the economist Gino Arias (1879–1940), examining more in detail the two seasons at the opposite ends of his life: the early one that saw him considerably committed to the Zionist cause and the one that, thirty years later, would force him to confront the racial laws of the Fascist regime.
Despite the seeming tragic continuity of these two phases, Arias’s case is a real historiographical paradox since, over the long span between the opposite ends of his biography, not only did he distance himself from the Zionist movement, but he also gradually laid the foundations for his upcoming and immediate dedication to Fascism; indeed, within the Fascist regime he would stand out as an authoritative and influential theorist of corporatism, the institutional solution Mussolini tried to exploit to organize the national economic life.
After carefully examining Arias’s early contributions to the Zionist cause (that include the establishment of the Florentine Zionist Group and that led him toward strongly nationalistic stances), this essay sums up Arias’s intellectual biography during the next years and then, thanks to unprecedented documents from the Italian Ministry of Interior, closely looks into his fate after his conversion to Catholicism in 1932 and up against the racial laws of 1938, as well as into his attempts to escape persecution. A few final observations will then try to highlight the dramatic exemplarity of his case.

Abstract
Purpose
The objective of this paper is to re‐appraise intra‐urban rent models in the context of a multi‐nodal landscape. Primarily, the study focuses on the early work of Alonso and, more recently, Di Pasquale and Wheaton. Although the latter use a more sophisticated approach, both models lead to similar outputs, notably a declining rent gradient from the central business district (CBD). However, throughout the twentieth century there has been a considerable process of urban industrial change. Di Pasquale and Wheaton recognise this and argue that this has led to an almost flat industrial rent gradient.
Design/methodology/approach
To assess the current impact on industrial rents a hedonic rent regression model is applied which enables us to standardise for property characteristics.
Findings
The results support the hypothesis that the rent gradient from the CBD for a large city is still downward‐sloping, albeit very shallow. More interesting is the significance of proximity to motorway junctions. The analysis supports the hypothesis of a multi‐nodal rent surface. Proximity to a motorway junction is the most important locational variable with a much steeper and negative gradient than that to the CBD, albeit over a shorter distance.
Originality/value
These results imply that the draw of the CBD in terms of agglomeration economies and its accessibility to labour for a city the size of Glasgow still remains, but its attractions are much denuded with the development of a national motorway network.

Abstract
Purpose
This study aims to investigate unripe carob pod as a source of antioxidant molecules useful in the eco-friendly synthesis of a gelatin conjugate. This one was involved in the preparation of gummies able to produce remarkable human health benefits.
Design/methodology/approach
Eco-friendly strategies (ultrasound-assisted extraction, low temperatures and eco-friendly solvents) were employed in the extraction of active molecules. Antioxidant molecules were involved in the grafting reaction with gelatin chains (ascorbic acid/hydrogen peroxide couple as initiator system). Gelatin conjugate represents a useful material able to prepare gummies with remarkable rheological and antioxidant performances over time.
Findings
Experimental results confirmed that the green approach allowed the achievement of extracts with remarkable antioxidant properties due to the presence of phenolic moieties. Gelatin conjugate synthesis preserved these functionalities, usefully exploited in the preparation of gummies with significant structural and biological features.
Originality/value
Compared to the literature data the preparation of the gummies with outstanding biological properties was performed by employing functional gelatin synthesized by an eco-friendly approach.

Abstract
Describes the experience of setting up a cooperative arm system based on individual open‐architecture controllers. Two six‐degree‐of‐freedom industrial manipulators, one of which is mounted on a moving track, are installed to realize a cooperative experimental set‐up. The main issues related to the cooperative manipulation are overviewed and its potential applications in industry are discussed. A brief description of the system’s components is given. The most relevant problems encountered in setting up the cooperative system based on individual control architectures are detailed. The result of the experience is that by using available industrial manipulators, rather than prototypes, and without re‐designing the controller hardware, it is possible to realize a cooperative manipulator system.

Abstract
Purpose
The purpose of this paper is to present the architectural principles and the services of the D-NET software toolkit. D-NET is a framework where designers and developers find the tools for constructing and operating aggregative infrastructures (systems for aggregating data sources with heterogeneous data models and technologies) in a cost-effective way. Designers and developers can select from a variety of D-NET data management services, can configure them to handle data according to given data models, and can construct autonomic workflows to obtain personalized aggregative infrastructures.
Design/methodology/approach
The paper provides a definition of aggregative infrastructures, sketching architecture, and components, as inspired by real-case examples. It then describes the limits of current solutions, which find their lacks in the realization and maintenance costs of such complex software. Finally, it proposes D-NET as an optimal solution for designers and developers willing to realize aggregative infrastructures. The D-NET architecture and services are presented, drawing a parallel with the ones of aggregative infrastructures. Finally, real-cases of D-NET are presented, to show-case the statement above.
Findings
The D-NET software toolkit is a general-purpose service-oriented framework where designers can construct customized, robust, scalable, autonomic aggregative infrastructures in a cost-effective way. D-NET is today adopted by several EC projects, national consortia and communities to create customized infrastructures under diverse application domains, and other organizations are enquiring for or are experimenting its adoption. Its customizability and extendibility make D-NET a suitable candidate for creating aggregative infrastructures mediating between different scientific domains and therefore supporting multi-disciplinary research.
Originality/value
D-NET is the first general-purpose framework of this kind. Other solutions are available in the literature but focus on specific use-cases and therefore suffer from the limited re-use in different contexts. Due to its maturity, D-NET can also be used by third-party organizations, not necessarily involved in the software design and maintenance.
