The purpose of this paper is to strive to close the current research gap pertaining to potential implications of the blockchain (BC) for sustainable business models (SBMs) in the agri-food industry.

To answer the research question, the authors utilised the Value Triangle framework by Biloslavo et al. (2018) in order to explore the potential innovation of BC for SBMs in the agri-food industry. Then, the authors apply it to an in-depth exploratory case study of the Placido Volpone winery. The authors draw data from strategic plans, annual reports, corporate website and a semi-structured interview with the winery's founder.

The authors show how BC technology could be a source of SBM innovation in the agri-food industry.

BC technology has the potential to significantly change SBMs. Given the huge set-up investments by the industry, academic research investigating potential implications and supporting companies in their application of BC is needed. This paper explores how the implications of BC as source of innovation on SBMs can be investigated.

The research results of this study can be used by company leaders and managers to support the development of SBMs through the introduction of BC technology in their business activities.

The paper is novel because it investigates the relationship between SBM innovation and BC providing theoretical justification to SBM technological innovation in an agri-food setting. Additionally, the paper provides an empirical application of the framework by Biloslavo et al. (2018) for understanding the development of SBM through BC in the agri-food industry.

Correctional facilities host a disproportionately high prevalence of HBV, HCV and HIV infection. We evaluated the prevalence of HBV and/or HCV co‐infection among HIV‐infected inmates entering our correctional facility. Over a 30‐month period, 173 consecutive HIV‐infected inmates entered our institution and were evaluated. HCV co‐infection was observed in more than 90% of the tested HIV‐infected inmates, past HBV infection in 77.4% and active HBV co‐infection in 6.7%; triple coinfection (HIV, HCV and HBs‐Ag positivity) was seen in 6.1% of them. Given the observed high prevalence of co‐infection, testing for HBV and HCV in all HIV‐infected inmates at entry in any correctional system is recommended to identify those in need of specific care and/or preventing interventions.

The purpose of this paper is to investigate the role of strategic communication during a change management process within the internationally famous Ferrari corporation. The aim is to show that strategic communication, through its main components, can be a pivotal lever that supports continuous improvement and helps drive organizational success.

The change management process at Ferrari is described and interpreted through the framework of the entrepreneurial organization theory (EOT), from which the four components of strategic communication are derived.

The paper explores the case of Ferrari, which started a reorganization process in which the main actors were employees and strategic communication represented the crucial component.

This paper focuses on one single organization. Additional research is needed to generalize the effectiveness of the proposed strategic communication model.

The paper shows that the four strategic communication components (i.e. aligning, energizing, visioning, and constituting), if applied in an integrated manner, can give insightful stimulus for the management of important change programs.

The paper contributes to the change management literature by linking strategic communication, continuous improvement and entrepreneurial theory.

The purpose of this paper is to analyse how sustainability is crucial in maintaining and assigning value to a common good. In particular, the paper identifies several characteristics of a business model that could be adopted to manage sustainable innovation strategies that respect the balance among environmental, social and commercial goals.

This case study involves Fontanafredda, an internationally recognised historical Italian wine company characterised by its highly innovative business approach and sustainable business model.

Fontanafredda’s approach is connected to the broader concept of the common good the winery has internalised to become an element of its competitive advantage and differentiation. The preservation of traditional values – primarily the respect and valuing of one’s own territory – is a key asset of the winery, which attaches great symbolic and concrete importance to these values.

The study uses a single case study approach and a qualitative method without quantifying the impact of every business choice. For theoretical implications, the study emphasises the strong connection between sustainability and innovation in the management of the common good.

Numerous practical implications are identified regarding several stakeholder groups, such as the management, owners, investors and the various entities linked to the regional promotion and tourism sectors.

This research explores how and why Fontanafredda amounts to more than simply wine production by focusing on the characteristics of its business model, which efficiently handles the link between innovation and heritage for common-good development.

The purpose of this paper is to evaluate the prevalence of HBV and/or HCV co-infection among HIV-infected inmates entering the correctional facility.

Prospective collection of data of HIV-infected inmates entered the institution over a ten-year period.

During study period 365 consecutive different inmates were evaluated. HCV co-infection was observed in more than 80 per cent of the tested HIV-infected inmates, past HBV infection in 71.6 per cent and active HBV co-infection was detected in 7.1 per cent; triple coinfection (HIV, HCV and HBs-Ag positivity) was present in 6 per cent of the total.

This study confirms high prevalence of co-infections among HIV-infected inmates. Testing for HBV and HCV in all HIV-infected inmates at entry in any correctional system is recommended to identify those in need of specific care and/or preventing interventions.

This paper aims to extend an efficient method to solve the global system of linear algebraic equations in the hybrid finite element method – boundary element method (FEM‐BEM) solution of open‐boundary skin effect problems. The extension covers the cases in which the skin effect problem is set in a truncated domain in which no homogeneous Dirichlet conditions are imposed.

The extended method is based on use of the generalized minimal residual (GMRES) solver, which is applied virtually to the reduced system of equations in which the unknowns are the nodal values of the normal derivative of the magnetic vector potential on the fictitious truncation boundary. In each step of the GMRES algorithm the FEM equations are solved by means of the standard complex conjugate gradient solver, whereas the BEM equations are not solved but used to perform fast matrix‐by‐vector multiplications. The BEM equations are written in a non‐conventional way, by making the nodes for the potential non‐coinciding with the nodes for its normal derivative.

The paper shows that the method proposed is very competitive with respect to other methods to solve open‐boundary skin effect problems.

The paper illustrates a new method to solve efficiently skin effect problems in open boundary domains by means of the hybrid FEM‐BEM method.

This article on Messedaglia might start with Schumpeter's words: “I have chosen him for mention because of the strategic position he holds in the history of Italian economics and statistics”. In fact the Italian history of economics in the nineteenth century is populated by many authors who were rather famous during their lifetime but less and less appreciated later. Generally speaking it can be said, again with Schumpeter, that “the economic research which was done during this period in the various centres of national life … was not on the same level with the achievements of either the earlier times of Beccaria and Verri or the later times of Pantaleoni and Pareto…. And if it is true that “the political and administrative structure of every nation reflects itself in the organisation of its scientific work” (ibid.) the difficulties faced by Italy, trying first to get rid of foreign domination and, secondly, to build national unity, can explain the trouble Italian economists have had in disentangling themselves from foreign influence and in avoiding divisions into regional schools of thought. Angelo Messedaglia is one of the few able to be original and not provincial, as will be shown later; instead, at this point it would seem useful to give a brief account of the historical situation of Italy in the nineteenth century.

The purpose of this paper is to investigate the most recurrent variables characterizing the collaborative relationships of industrial symbiosis (IS) (hereinafter also referred to as “anatomic” variables) established in the attempt to adopt circular economy (CE) by collecting evidence from a rich empirical set of implementation cases in Italy.

The current literature on IS was reviewed, and a content analysis was performed to identify and define the “anatomic” variables affecting its adoption in the circular economy. We followed a multiple-case study methodology investigating 50 cases of IS in Italy and performed a content analysis of the “anatomic” variables characterizing each case.

This research proposes the “anatomic” variables (i.e. industrial sectors involved, public actors involvement, governmental support, facilitator involvement and geographical proximity) explaining the cases of IS in the circular economy. Each “anatomic” variable is discussed at length based on the empirical evidence collected, with a particular reference to the impact on the different development strategies (i.e. “bottom-up” and “top-down”) in the cases observed.

Current literature on IS focuses on a sub-set of variables characterizing collaboration in IS. This research builds on extant literature to define a new framework of five purposeful “anatomic” variables defining IS in the circular economy. Moreover, we also collect and discuss a broad variety of empirical evidence in what is a still under-investigated context (i.e. Italy).

The purpose of this paper is to fill a gap in the literature regarding the open innovation management approaches that small and medium-sized enterprises (SMEs) can use to access digital technologies and incorporate them into their organizational processes. The research question is: What organizational and process-level managerial actions do SMEs take to successfully access and implement digital technologies within their organizational processes?

Using Guertler et al.'s (2020) Action Innovation Management Research (AIM-R) framework, this study examines the digital transformation experiences of 10 European SMEs to gain insights into the managerial actions that foster successful digital transformation.

The findings of the paper reveal two major contributions. First, a digital transformation roadmap for SMEs is proposed, with a focus on accessing external resources and reconfiguring internal ones to ease their digital transformation journey. Second, three distinct paradoxes that influence the digital transformation process in SMEs are highlighted, providing useful insights into the challenges and tensions SMEs face during this journey.

This paper provides a unique perspective on the digital transformation of SMEs by examining the managerial actions required for successful technology adoption and revealing the paradoxes that may emerge during this transformative process. The findings form the basis for future research, deepening our understanding of digital transformation in SMEs and providing actionable advice to managers and practitioners navigating this journey.
