This paper aims to show results of numerical simulations of transonic flow around a supercritical airfoil at chord Reynolds number Re_c = 3 × 10⁶, with the aim of elucidating the mechanisms responsible for large-scale shock oscillations, namely, transonic buffet.

Unsteady Reynolds-averaged Navier–Stokes simulations and detached-eddy simulations provide a preliminary buffet map, while a high fidelity implicit large-eddy simulation with an upstream laminar boundary layer is used to ascertain the physical feasibility of the various buffet mechanisms. Numerical experiments with unsteady RANS highlight the role of waves travelling on pressure side in the buffet mechanism. Estimates of the propagation velocities of coherent disturbances and of acoustic waves are obtained, to check the validity of popular mechanisms based on acoustic feedback from the trailing edge.

Unsteady RANS numerical experiments demonstrate that the pressure side of the airfoil plays a marginal role in the buffet mechanism. Implicit LES data show that the only plausible self-sustaining mechanism involves waves scattered from the trailing edge and penetrating the sonic region from above the suction side shock. An interesting side result of this study is that buffet appears to be more intense in the case that the boundary layer state upstream of the shock is turbulent, rather than laminar.

The results of the study will be of interest to any researcher involved with transonic buffet.

The purpose of this paper is to contribute to the literature on financial reporting quality (FRQ) within family firms (FFs), assessing whether longevity can determine a different propensity to earning management (EM) behaviors.

The sample, composed by Italian and Brazilian listed family (and non-family) firms, is segregated into old and young. For each subsample, unsigned discretionary accruals are calculated, using two different EM models. A linear regression model is then proposed, together with some robustness tests, to confirm the research hypothesis.

The outcome is that, within FFs, the entrenchment effect seems to be diminishing with the company’s age, up to become lower than the alignment effect. With some caveat, research also demonstrates that old FFs are more propense to supply higher FRQ than any other subsample group.

The authors demonstrated that, in terms of EM decision process, FFs become virtuous just with time. More research is needed to evaluate the impact of the share and management control separately and to analyze different generation segmentation.

This paper could help non-family stakeholders, as it shows that different company types (family vs non-family), at a different stage of the life-cycle (young vs old) have a different attitude toward FRQ. On the other hand, family owners could exploit the longevity as a value driver.

This paper suggests that agency theory and socio-emotional theory are complementary in explaining the family control role in earnings management decisions. The study also contributes to the debate of FF homogeneity and on risk behavior in FFs, often portrayed as having a patient capital.

This paper aims to focus on distributed technologies with the aim of highlighting their economic-organizational dimensions. In particular, the contribution first presents a deeper understanding of the nature and the dynamics of the economies and diseconomies that arise from the adoption and diffusion of distributed technologies. Second, it aims to shed light on the increasing tension between the hierarchy-based model of production and peer-to-peer (p2p) production, which involves the pervasive diffusion of distributed technologies.

Adopting an economic-organizational perspective, which is deeply rooted in the related extant literature, an analytically consistent model is developed to simultaneously take into account the following variables: adoption density independent variable) and economies of knowledge integration and organizational diseconomies (the costs of a loss of control and the costs of organizational decoupling and recoupling) as dependent variables.

Distributed technologies allow access to a large quantity and a wide variety of cognitive slacks that have not been possible until now. In doing so, they are leading the transition towards p2p. This is an emerging production paradigm that is characterized – with respect to mass production – by a shift in the relative importance of cognitive slack in comparison with tangible slack. Nevertheless, the unrestrainable diffusion of distributed technologies is not neutral for organizations. On the one hand, these technologies allow for the integration of economies of knowledge, and on the other hand, they involve organizational diseconomies that should not be ignored by managers and researchers.

This paper fills a gap in the literature by developing a consistent analytical framework that simultaneously takes into account the economies of knowledge integration and potential organizational diseconomies (the costs of coordination and the loss of control) that arise from the adoption and diffusion of distributed technologies.

Scholarly interest in the business effects of organised crime (OC) has recently increased. This study aims to conduct a systematic literature review (SLR) on the conditions under which OC could pose a threat to or take control of firms within a particular context.

We use narrative synthesis and thematic analysis, with a sample of 46 theoretical and empirical studies published over the past 30 years on the relationship between OC and firms within the disciplines of Business, Management and Accounting (BMA).

SLR and thematic analysis show that scholarly interest has focused on four key domains: OC as a firm, the impact of OC on firms, firms’ efforts to counter OC’s influence and governmental interventions. Using medical metaphors, we also develop a diagram depicting the interplay between OC and firms within the BMA literature.

This study contributes to the literature shaping an agenda to steer future research towards these four key themes. The effectiveness of anti-OC tools and measures depends on a thorough understanding of local norms, behaviours and business practices. In addition to measurement and methodological challenges, several grey areas remain, including the distinction between criminal enterprises and legitimate businesses. Ambiguities also surround the circumstances under which the OC preys upon firms or employs them to establish dominance over a territory.

Negativity towards a brand is typically conceived as a significant problem for brand managers. This paper aims to show that negativity towards a brand can represent an opportunity for companies when brand polarization occurs. To this end, the paper offers a new conception of the brand polarization phenomenon and reports exploratory findings on the benefits of consumers’ negativity towards brands in the context of brand polarization.

To develop a conception of brand polarization, the paper builds on research on polarizing brands and extends it by integrating insights from systematic literature reviews in three bodies of literature: scholarship on brand rivalry and, separately, polarization in political science and social psychology. Using qualitative data from 22 semi-structured interviews, the paper explores possible advantages of brand polarization.

This paper defines the brand polarization phenomenon and identifies multiple perspectives on brand polarization. Specifically, the findings highlight three distinct parties that can benefit from brand polarization: the polarizing brand as an independent entity; the brand team behind the polarizing brand; and the passionate consumers involved with the polarizing brand. The data reveal specific advantages of brand polarization associated with the three parties involved.

Managers of brands with a polarizing nature could benefit from having identified a group of lovers and a group of haters, as this could allow them to improve their focus when developing and implementing the brands’ strategies.

This exploratory study is the first explicitly focusing on the brand polarization phenomenon and approaches negativity towards brands as a potential opportunity.

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.

The purpose of this paper is to extend the understanding of innovation in service ecosystems by focussing on the role of values resonance in relation to the integration of brands, service systems and experience rooms.

An empirical, explorative case study of an innovative service system is carried out using a narrative approach and presented in the form of a saga.

Insights gleaned from the empirical study are used for conceptual developments. Analysis of the empirical case study is presented as four lessons linked to values, brands, service systems and experience rooms.

The paper extends a conceptual framework of innovative resource integration in service ecosystems. The paper also contributes four propositions to inform theory: values resonance is a basis for service innovation, the innovative integration of brands based on values resonance can foster innovation, the integration of resources across service system boundaries grounded in values resonance can enable innovation and the integration of experience rooms into a coherent servicescape based on values resonance can support novel forms of resource integration and value co-creation efforts in service ecosystems.

Looks at the first 100 years of Italian cinema examining its role in Italy’s recent history. Provides a bibliography of major film directors, Italian cinema sources, reference works, histories, themes, theory and criticism and articles in journals.

The paper aims to investigate pro-social behaviour of Italian consumers during the decision-making process of buying food produced in lands confiscated from Mafia-type organisations. This is assumed as a form of buycotting, thus as an ethical purchasing choice to contribute to social change.

Data from 339 interviews were elaborated with a cluster analysis. The difference between groups was confirmed using MANOVA, whereas the multivariate multiple regression analysis was carried out to assess the difference between clusters.

Three types of consumer groups are identified: absolutists, exceptionists and subjectivists. Coherent with previous studies, findings also highlight the relevance of information acquisition and of the self-effectiveness perception as key factors to stimulate pro-social behaviours.

With a social marketing perspective, the paper offers useful suggestions to promote political consumerism as a critical choice to contribute to fight against Mafia-type organisations and to spread a culture of lawfulness.
