A von Bertalanffy Growth Model with a Seasonally Varying Coefficient

, 1978
The von Bertalanffy model of body growth is inappropriate for organisms whose growth is restricted to a seasonal period because it assumes that growth rate is invariant with time.

From Sustainable Practices to SME Resilience: An Integrative, Systems‐Based Review With Propositions

Business Strategy and the Environment, EarlyView.
ABSTRACT This integrative review examines how sustainable practices foster organizational resilience in small‐ and medium‐sized enterprises (SMEs), supporting long‐term sustainable development. Existing resilience models often overlook SMEs' distinctive challenges—limited resources and managerial short‐termism—whereas research linking day‐to‐day ...

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

From Nature to Supply Chain: Exploring Biomimicry‐Based Pathways to Sustainability and Competitive Advantage

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Inspired by insights gleaned from biomimicry theory, this paper addresses the persistent lack of theoretically grounded research in sustainable supply chain management (SSCM) and examines how nature‐inspired biomimicry principles could enhance various dimensions of its competitiveness. This study's theoretical contribution lies in its proposal

Analyzing Growth Curves of Turkeys Reared in Different Breeding Systems (Intensive and Free-Range) with some Nonlinear Models

Brazilian Journal of Poultry Science
The objective of this study was to identify the growth curve of live weight of turkeys reared in different systems (intensive and free- range) with the best mathematical model. To achieve this goal, the live weight of male and female turkeys (Large White)

Bayesian approach for evaluating ammonia volatilization nitrogen losses in fertilizers applied to coffee plants [PDF]

Ciência e Agrotecnologia
Ammonia loss through volatilization is an important reason for the lower effectiveness of nitrogen fertilizers in coffee plants. The Bayesian approach uses informative prior distributions, which help improve the precision and accuracy of inferences ...

A Formulation of the von Bertalanffy Growth Curve when the Growth Rate is Roughly Constant

, 1969
The author contends that the parameters of any growth curve should be a direct description of the graphical appearance of the data. For growth that is even approximately linear this is not true of the von Bertalanffy curve in its usual form (von ...

Translating Riedl: The Circulation and Operationalisation of Evolutionary Ideas

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Rupert Riedl's Order in Living Organisms proposed a systems theory of evolution decades before the concepts it pioneered—homology, burden, the imitative epigenotype—reached the agenda of evolutionary biology. This paper reconstructs the lineages that operationalized his insights across several fields and explores the internal and external reasons for ...
