Does the CEO's Attention Affect How Well the Firm Performs Environmentally?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study explores whether CEOs' environmental attention (CEA) enhances firms' environmental performance. Drawing on attention‐based and upper echelons theories, which emphasize that executives' cognitive focus shapes organizational outcomes, we argue that CEOs who devote greater attention to environmental issues are more likely to integrate ...

Determining the Nutritional Potential of Ancient Wheat Species: A Closer Look at Starch and Protein Digestibility, and Phenolic Acid Content

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The recent trend towards healthy food choices and sustainable agriculture has revived interest in underutilized wheat species such as emmer, einkorn, and spelt. Given these developments, the objective of the study was to compare the differences in chemical composition and digestibility characteristics among ...

Stability and Bifurcation Analysis of a Predator–Prey Model With Generalized Allee Effect on the Prey Population

Journal of Mathematics
This research describes a predator–prey system that takes into account the generalized Allee effect, aiming to derive general conclusions applicable to specific Allee effect functions through the use of a generalized function.

Comparative Evaluation of Starch and Protein Characteristics in Ancient Wheat Species

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Driven by increasing consumer demand for nutrient‐dense and more sustainable food options, ancient wheat species present a promising opportunity due to their environmental adaptability and perceived health benefits. Therefore, this study aims to evaluate the starch and protein characteristics of ancient wheat species,

Evolutionary dynamics and strong Allee effects

Journal of Biological Dynamics, 2012
We describe the dynamics of an evolutionary model for a population subject to a strong Allee effect. The model assumes that the carrying capacity k(u), inherent growth rate r(u), and Allee threshold a(u) are functions of a mean phenotypic trait u subject to evolution. The model is a plane autonomous system that describes the coupled population and mean

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Impact of Refuge on the Dynamical Behavior of a Tri-Trophic Food Chain Model Under Allee Effect in Prey Species [PDF]

EPJ Web of Conferences
The current study focuses on the impact of refuge on the dynamical behaviour of a tri-trophic food chain model under the Allee effect in prey species. The model investigates the asymptotic behaviour of multiple equilibrium points and the influence of the

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Allee effects in marine systems [PDF]

Marine Ecology Progress Series, 2004
The fitness or population growth rate of populations with Allee effects increases with in- creasing population size or density up to a certain threshold. Allee effects are possible in marine pop- ulations, as they are less open than has been assumed and may have a metapopulation structure.

Expansion of the Brazilian Sugarcane Bioenergy System Promotes Greenhouse Emission Reductions and Sustainable Development Without Compromising Food Security

Sustainable Development, EarlyView.
ABSTRACT The growing global demand for biofuels has raised concern about compromising food security. This study uses two independent economy‐wide models to evaluate the impact of expanding the Brazilian sugarcane bioenergy system on economic growth, social outcomes and food security.
