Optimal and near-optimal exponent-pairs for the Bertalanffy-Pütter growth model [PDF]

PeerJ, 2018
The Bertalanffy–Pütter growth model describes mass m at age t by means of the differential equation dm/dt = p * ma − q * mb. The special case using the von Bertalanffy exponent-pair a = 2/3 and b = 1 is most common (it corresponds to the von Bertalanffy ...

Symbolic Versus Substantive ESG Practices: A Systematic Review and Integrative Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT ESG reporting is widespread, but symbolic commitments do not always reflect substantive practices. This study conducts a systematic literature review of 62 empirical articles published between 2021 and 2025 to synthesize the main determinants and consequences of this disclosure–performance misalignment in ESG reporting (commonly referred to as
