A Massively Parallel Branch-&-Bound Algorithm for the Balanced Minimum Evolution Problem

The Balanced Minimum Evolution Problem (BMEP) is an APX}-hard network design problem that consists of finding a phylogeny that minimizes the cross-entropy of the molecular sequences extracted from a given set of taxa. By combining massive parallelism with recent theoretical advances on the polyhedral combinatorics of the problem and new insights on the relationships between the BMEP and information entropy, we design a new exact solution algorithm that proves to be up to an order of magnitude...

The start-up’s roadmap to private equity financing: substituting discounts with a premium in valuation for growth

The authors examine financial marketing and contingent factors, as enablers of a “patent premium” by private equity (PE) investors targeting start-ups in their growth and expansion stages. Design/methodology/approach – Drawing from the contingency, innovation and signaling theories, the authors collect patent reco...

Risk disclosure in sustainability reports: Empirical evidence from the energy sector

Recently, companies in the energy sector have faced multiple financial and environmental risks. This finding demonstrates the need for energy companies to disclose risk information. However, academic attention on risk disclosure (RD) remains limited. Through manual content analysis and a regression model, this study examines the effect of the features of the board of directors and audit committee on the RD level in sustainability reports. The empirical findings reveal that the size and indepe...

Nuovi modelli eutagogici per la formazione continua. Il diritto soggettivo alla formazione e lo sviluppo dell’agency capacitante per la transizione digitale

Today the new work processes, connected and integrated with artificial intelligence, design real adaptive-transformative ecosystems in which workers’ upskilling and reskilling needs emerge (OCSE, 2021, PNNR 2021, INAPP, 2021; ANPAL, 2020). The essay highlights the pedagogical models transformation for continuing education in an heutagogical and capable key as a basis for a full subjective right to training in the digital transition. The heutagogical model (Hase, Blaschke, 2021) for learning e...
