Hilfer-Prabhakar Derivatives and Some Applications

, 2014
We present a generalization of Hilfer derivatives in which Riemann--Liouville integrals are replaced by more general Prabhakar integrals. We analyze and discuss its properties.

From Capabilities to Competitive Greening: Managerial Commitment and Green Shared Vision as Serial Mediators in Energy‐Sector SMEs

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on dynamic capabilities view and upper echelons theory, this study shows how energy‐sector SMEs convert dynamic capabilities into green competitive advantage. We theorize that sensing–seizing–reconfiguring routines are associated with green competitive advantage only when top managers visibly prioritize environmental goals and foster a

Minimum energy control of fractional positive continuous-time linear systems using Caputo-Fabrizio definition

Bulletin of the Polish Academy of Sciences Technical Sciences, 2017
Abstract The Caputo-Fabrizio definition of the fractional derivative is applied to minimum energy control of fractional positive continuous- time linear systems with bounded inputs. Conditions for the reachability of standard and positive fractional linear continuous-time systems are established.

A comment on some new definitions of fractional derivative

, 2018
After reviewing the definition of two differential operators which have been recently introduced by Caputo and Fabrizio and, separately, by Atangana and Baleanu, we present an argument for which these two integro-differential operators can be understood ...

Critical Discourse Analysis in Corporate Reports: Legitimation Strategies in the Context of Environmental Controversies

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the use of environmental disclosure as a strategic tool to manage legitimacy crises in a mining company, adopting critical discourse analysis (CDA) as the main methodology. Focusing on a case of environmental disaster, this research reveals how corporate narratives can be manipulated to minimize responsibility and reinforce
