The purpose of this paper is to evaluate the applicative potentiality of functional/self-responsive materials in aeronautics. In particular, the study aims to experimentally validate the enhancement of structural performances of carbon fibers samples in the presence of nanofillers, as multi-walled carbon nanontubes or microcapsules for the self-healing functionality.

The paper opted for a mechanical study. Experimental static and dynamic tests on “blank” and modified formulations were performed in order to estimate both strength and damping parameters. A cantilever beam test set-up has been proposed. As a parallel activity, a numerical FE approach has been introduced to assess the correct modeling of the system.

The paper provides practical and empirical insights about how self-responsive materials react to mechanical solicitations. It suggests that reinforcing a sample positively affects the samples properties since they, de facto, improve the global structural performance. This work highlights that the addition of carbon nanotubes strongly improves the mechanical properties with a simultaneous slight enhancement in the damping performance. Damping properties are, instead, strongly enhanced by the addition of self-healing components. A balanced combination of both fillers could be adopted to increase electrical conductivity and to improve global performance in damping and auto-repairing properties.

The paper includes implications for the use of lightweight composite materials in aeronautics.

This paper fulfills an identified need to study new lightweight self-responsive smart materials for aeronautical structural application.

This teaching case seeks to explain the main aspects of Acciona's sustainability strategy and the process of transformation of the company after the new CEO took office in 2004. It also aims to present some possible difficulties of maintaining such strategies in the new economic and political environment. The purpose of the case is to show how three aspects play a relevant role in a company's transformation towards sustainability: cultural change; collaboration with external stakeholders; and the innovations introduced.

The paper presents a case study that narrates the process of six years of transformation towards sustainability of a company. The case was constructed through the analysis of company documents and several interviews with key actors in the company as well as external stakeholders.

The paper shows how cultural change, collaboration with external stakeholders and innovation form a vital combination in the transformation process towards sustainability. It also reveals that acquisitions and internationalization can help accelerate or consolidate this process.

The paper is presented as a teaching case with discussion questions at the end. The aim is to engage readers and participants in educational and training programmes in discussions about the factors that may contribute to start and maintain a transformation towards sustainability. The practical implication of the paper is to show how cultural factors, collaboration and innovation form a vital combination for changing the way businesses do things.

The value of the case lies in showing how business efforts of embedding sustainability into business practice can be more effective by combining cultural factors, collaboration and innovation.

What has happened, after 50 years of persistent (deepening, expanding) European integration, to the domestic politics of the nation states involved in this increasingly dense institutional net (whatever its ambiguous nature, inter-governmental or supra-national or both at the same time) is a question of growing importance. This environment, within which the politics of European nation states takes place, has undoubtedly gained a growing importance in itself and a stronger relevance for crucial aspects of domestic political life. More precisely, it must be asked what has been altered in the traditional “setting” within which domestic politics used to develop, how domestic political actors bring into their political calculations the new conditions and how they are affected by them.

This paper aims to review and critique the knowledge management (KM) literature within small and medium enterprises (SMEs), offers an overview of the state of research and outline a future research agenda.

Papers published in KM journals are analysed using a structured literature review methodology. The paper analyses 89 papers published in ten journals specialising in the field of KM.

KM within SMEs is a research area of growing importance. Findings show that literature on KM in SMEs is fragmented and dominated by unrelated research, with few comparative studies between countries and several countries receiving little attention. Additionally, different definitions of SMEs are used and different kinds of SMEs (e.g. micro, small and medium) are often treated as equivalent, making comparison almost impossible. The results show a failure to address the implications of findings for practitioners and policymakers, which risks relegating the KM research on SMEs to irrelevance.

The paper presents a comprehensive structured literature review of the articles published in KM journals. The paper’s findings can offer insights into future research avenues.

The paper aims to investigate the emerging issue of knowledge transfer and organisational performance. The purpose of this paper is to investigate the importance of knowledge transfer in obtaining high and positive results in organisations, in particular, studying the role of managers’ skills transfer and which conditions help to achieve positive performance.

The research analyses 41 cases of coaches that managed clubs competing in the major international leagues in the 2014–2015 season and that moved to a new club over the past five seasons. The authors employ a qualitative comparative analysis (QCA) methodology. According to the research question, the outcome variable used is the team sport performance improvement. As explanatory variables, the authors focus on five main variables: the history of coach transfers; the staff transferred; the players transferred; investments in new players and the competitiveness.

The overall results show that when specific conditions are realised simultaneously, they allow team performance improvement, even if the literature states that the coach transfers show a negative impact on outcomes. Interestingly, this work reaches contrasting results because it shows the need for the coexistence of combinations of variables to achieve the transferability of managers’ capabilities and performance.

The paper is novel because it presents a QCA that tries to understand which conditions, factors and contexts help knowledge to be transferred and to contribute to the successful run of organisations.

The purpose of this paper is to investigate intellectual capital (IC) discussions held between investors using Web 2.0 tools. More precisely, this paper investigates the determinants of IC disclosures (ICDs) on internet stock message boards (IMBs).

Four hypotheses were developed and tested through content analysis of 60,996 messages posted on two main IMBs, Yahoo!Finance and TheLion.com, followed by descriptive statistics and logistic regression testing.

The findings show that Web 2.0 is bringing new opportunities to disclose IC. Traditional theories, such as agency, stakeholder, signalling, and legitimacy theory, cannot be applied to the Web 2.0 context. Therefore, a new approach that focusses more on the personal motivations for disclosing IC is called for. At a glance, the results show that IC is disclosed on IMBs, and several elements influence both the quantity and quality of those disclosures. Sometimes “trolls” disturb the dialogue and discourage participation by other investors. Conversely, online influencers facilitate ICD. To filter messages, the time of posting, the length of the messages, and the sentiment the messages contain should be considered along with the author of the message.

This paper contributes to the existing literature by investigating the IC disclosed on IMBs. The findings provide insights about how ICDs are developed using Web 2.0 tools.

The purpose of this paper is to introduce this special issue, conceptualized and realized by a group of scholars engaged in the Global Organizational Learning and Development Network (GOLDEN) for Sustainability programme. It aims to adopt the overarching research question of the GOLDEN research programme “How do firms learn to integrate and manage sustainability in their business models, including their organizational purpose, strategy, processes, systems and culture?” as the guiding principle for case selection.

The paper first presents the key ideas underpinning the previous research question and illustrates the research approach and agenda of GOLDEN for Sustainability. Second, it introduces the eight case studies presented in this special issue.

The cases offer good illustrations of the ongoing transition by both medium‐sized and multinational corporations dealing with learning and change challenges posed by the identification and management of sustainability issues. The selected cases represent firms operating in diverse contexts and industries, and are developed by scholars specializing in various fields connected to corporate responsibility and sustainability.

The paper presents cases of organizations that have made sense of the sustainability challenge and also the different approaches taken to tackle the challenge, and the results stemming from their efforts..

Though the circular economy (CE) is a current buzzword, this still lacks a precise definition. In the absence of a clear notion of what that term includes, actions taken by the government and companies may not be well informed. In particular, those actions need to consider what people mean when people talk about the CE, either to refocus people's decisions or to undertake a more effective communications strategy.

Since people voice people's opinions mainly through social media nowadays, special attention has to be paid to discussions on those media. In this paper, the authors focus on Twitter as a popular social platform to deliver one's thoughts quickly and fast. The authors' research aim is to get the perceptions of people about the CE. After collecting more than 100,000 tweets over 16 weeks, the authors analyse those tweets to understand the public discussion about the CE. The authors conduct a frequency analysis of the most recurring words, including the words' association with other words in the same context and categorise them into a set of topics.

The authors show that the discussion focuses on the usage of resources and materials that heavily endanger sustainability, i.e. carbon and plastic and the harmful habit of wasting. On the other hand, the two most common good practices associated with the CE and sustainability emerge as recycling and reuse (the latter being mentioned far less). Also, the business side of the CE appears to be relevant.

The outcome of this analysis can drive suitable communication strategies by which companies and governments interested in the development of the CE can understand what is actually discussed on social media and call for the attention.

This paper addresses the lack of a standard definition the authors highlighted in the Introduction. The results confirm that people understand CE by looking both at CE's constituent activities and CE's expected consequences, namely the reduction of waste, the transition to a green economy free of plastic and other pollutants and the improvement of the world climate.

The Italian government addressed the first wave of its COVID-19 outbreak with a series of social restrictions and calculative practices, all branded with the slogan #istayathome. The hashtag quickly went viral, becoming both a mandate and a mantra and, as the crisis played out, we witnessed the rise of the Italian social movement #istayathome. This study examines how the government's calculative practices led to #istayathome and the constituents that shaped this social movement.

The authors embrace social movement theory and the collective identity perspective to examine #istayathome as a collective action and social movement. Using passive netnography, text mining and interpretative text analysis enhanced by machine learning, the authors analysed just over 350,000 tweets made during the period March to May 2020, each brandishing the hashtag #istayathome.

The #istayathome movement gained traction as a response to the Italian government's call for collective action. Thus, people became an active part of mobilising collective responsibility, enhancing the government's plans. A collective identity on the part of the Italian people sustained the mass mobilisation, driven by cohesion, solidarity and a deep cultural trauma from COVID-19's dramatic effects. Popular culture and Italy's long traditions also helped to form the collective identity of #istayathome. This study found that calculative practices acted as a persuasive technology in forming this collective identity and mobilising people's collective action. Numbers stimulated the cognitive, moral and emotional connections of the social ties shaping collective identity and responsibility. Thus, through collective identity, calculative practices indirectly influenced mass social behaviors and the social movement.

This study offers a novel theoretical perspective and empirical knowledge to explain how government power affects people's culture and everyday life. It unveils the sociological drivers that mobilise collective behaviors and enriches the accounting literature on the effects of calculative practices in managing emergencies. The study contributes to theory by providing an understanding of how calculative practices can influence collective behaviors and can be used to construct informal networks that go beyond the government's traditional formalities.
