American Journal of Agricultural Economics, EarlyView.Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Lie triple derivation and Lie bi-derivation on quaternion rings
Miskolc Mathematical NotesIn this study, we prove the existence of the central Lie bi-derivation for the ring with identity on the quaternion ring. We also describe the triple Lie derivation using the Jordan derivation on the aforementioned ring.

Australian Journal of Social Issues, EarlyView.ABSTRACT This article reflects on the construction of a supportive community of Black Afro‐diasporic graduate students and their supervisors researching issues relating to race in the field of education in Australia. It draws on the concept of marronage—a term rooted in the fugitive act of becoming a maroon, where enslaved people enacted an escape in ...

Jordan (α,β)-Derivations on Operator Algebras
Journal of Function Spaces, 2017 Let A be a CSL subalgebra of a von Neumann algebra acting on a Hilbert space H. It is shown that any Jordan (α,β)-derivation on A is an (α,β)-derivation, where α,β are any automorphisms on A. Moreover, the nth power (α,β)-maps on A are investigated.

ON JORDAN IDEALS AND JORDAN DERIVATIONS OF PRIME RINGS
Demonstratio Mathematica, 2004 A classical result by \textit{I. N. Herstein} [Proc. Am. Math. Soc. 8, 1104-1110 (1958; Zbl 0216.07202)] states that a Jordan derivation of a prime ring of characteristic not 2 is a derivation. The main result of the paper shows that the same is true on Jordan ideals of prime rings that are simultaneously subrings.

Jordan and Jordan higher all-derivable points of some algebras [PDF]
Linear and Multilinear Algebra, 2013 In this paper, we characterize Jordan derivable mappings in terms of Peirce decomposition and determine Jordan all-derivable points for some general bimodules. Then we generalize the results to the case of Jordan higher derivable mappings. An immediate application of our main results shows that for a nest $\mathcal{N}$ on a Banach $X$ with the ...

Nonlinear Mixed Jordan Triple $ * $-Derivations on $ * $-Algebras
Siberian Mathematical Journal, 2022 Let $\mathcal {A}$ be a unital $\ast$-algebra. For $A, B\in\mathcal{A}$, define by $[A, B]_{*}=AB-BA^{\ast}$ and $A\bullet B=AB+BA^{\ast}$ the new products of $A$ and $B$. In this paper, under some mild conditions on $\mathcal {A}$, it is shown that a map $ :\mathcal {A}\rightarrow \mathcal {A}$ satisfies $ ([A\bullet B, C]_{*})=[ (A)\bullet B, C]_{*

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

Jordan *-derivations of standard operator algebras [PDF]
Proceedings of the American Mathematical Society, 1994 Let H H be a real or complex Hilbert space, dim H > 1 \dim H > 1 , and B ( H ) \mathcal {B}(H) the algebra of all bounded linear operators on H H .

SkelPy: A graphic user interface–based approach for skeletonizing fungal networks
Applications in Plant Sciences, EarlyView.Abstract Premise Traditional methods to quantify mycelial growth rely on destructive sampling to quantify biomass. Moreover, these approaches limit continuous observation and require a sufficient mass to measure. Recent work examines hyphal network traits by reconstructing the hyphal network from spatial coordinates via images, providing information ...
