Is It a Matter of Visibility Over Viability? CEO Narcissism and the Strategic Trade‐Off in Corporate Diversification

open access: yesStrategic Change, EarlyView.
ABSTRACT This study examines how CEO narcissism shapes corporate diversification strategies, addressing gaps in upper echelon and agency theories. Using a sample of 388 CEOs across 319 firms, we find that narcissistic CEOs drive higher levels of overall corporate diversification but exhibit a strategic trade‐off: they strongly favor unrelated ...

Matching the Alcubierre and Minkowski spacetimes

open access: yesEuropean Physical Journal C: Particles and Fields
This work analyzes the Darmois junction conditions matching an interior Alcubierre warp drive spacetime to an exterior Minkowski geometry. The joining hypersurface requires that the shift vector of the warp drive spacetime satisfy the solution of a ...

The use of edible insects in human food

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract The world population is expected to reach approximately 10 billion people by 2050, which will significantly increase global food demand and may lead to agricultural shortages and a higher risk of food insecurity. In this context, this review discusses the potential of insects as alternative sources of animal protein, addressing their ...

A New Efficient Hybrid Method Based on FEM and FDM for Solving Burgers’ Equation with Forcing Term

open access: yesJournal of Applied Mathematics
This paper presents a study on the numerical solutions of the Burgers’ equation with forcing effects. The article proposes three hybrid methods that combine two-point, three-point, and four-point discretization in time with the Galerkin finite element ...

Effect of pork carnosine level on lipid and protein oxidation markers during in vitro co‐digestion in a Mediterranean meal model

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study assessed the effects of dietary carnosine during the in vitro digestion of a healthy meal model based on the Mediterranean diet, comprising lean pork enriched with two levels of carnosine, whole grain bread, tomato, onion, and olive oil.

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

open access: yesLaser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

open access: yesOikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Caloric restriction‐mediated reproductive lifespan extension across multiple strains of the clonal aquatic plant Lemna turionifera

open access: yesOikos, EarlyView.
Lifespan extension due to caloric restriction (CR) is a well‐established aspect of animal senescence that has been observed in many taxa. Contrastingly, there is much less evidence in plants, even though it is straightforward to manipulate CR by restricting photosynthesis through reduction in light intensity.

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

open access: yesOikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.
