The 'slow-burn effect' of human trafficking following disaster. [PDF]

Disasters
Abstract A disaster is frequently cited as a driver of human trafficking, with claims that earthquakes, tsunamis, or typhoons create a chaotic post‐calamity environment ripe for traffickers to recruit their victims. Theory suggests that increased poverty, displacement, and a breakdown of law and order contribute to this situation.

A KIND OF GRAPH STRUCTURE ASSOCIATED WITH ZERO-DIVISORS OF MONOID RINGS [PDF]

Journal of Algebraic Systems
Let $R$ be an associative ring and $M$ be a monoid‎. ‎In this paper‎, ‎we introduce new kind of graph structure asociated with zero-divisors of monoid ring $R[M]$‎, ‎calling it the $M$-Armendariz graph of a ring $R$ and denoted by $A(R,M)$‎.

Extension of Antoine’s Ring Construction

International Journal of Mathematics and Mathematical Sciences, 2019
This article concerns a kind of extension of Antoine’s ring construction which is unit-IFP and Armendariz. Such extensions are also shown to be unit-IFP and Armendariz, by which we may extend the classes of unit-IFP and Armendariz rings.

Weak Quasi-Armendariz Rings

Algebra Colloquium, 2011
In this paper, we introduce and study weak quasi-Armendariz rings which unify the notions of weak Armendariz rings and quasi-Armendariz rings. It is shown that the weak quasi-Armendarizness is a Morita invariant property. For a semiprime ring R, it is shown that R[x]/〈xn〉 is weak quasi-Armendariz, where R[x] is the polynomial ring over R and 〈xn〉 is ...

Weak Armendariz Ideals

پژوهش‌های ریاضی, 2021
In this article, we introduce the weak Armendariz ideals as a generalization of the Armendariz ideals and we examine its properties, its relation to other structures.

On a theorem of McCoy [PDF]

Mathematica Bohemica
We study McCoy's theorem to the skew Hurwitz series ring $({\rm HR}, \omega)$ for some different classes of rings such as: semiprime rings, APP rings and skew Hurwitz serieswise quasi-Armendariz rings.

The Armendariz module and its application to the Ikeda-Nakayama module

International Journal of Mathematics and Mathematical Sciences, 2006
A ring R is called a right Ikeda-Nakayama (for short IN-ring) if the left annihilator of the intersection of any two right ideals is the sum of the left annihilators, that is, if ℓ(I∩J)=ℓ(I)+ℓ(J) for all right ideals I and J of R. R is called Armendariz

Properties of Armendariz rings and weak Armendariz rings

Publications de l'Institut Mathematique, 2009
We consider some properties of Armendariz and rigid rings. We prove that the direct product of rigid (weak rigid), weak Armendariz rings is a rigid (weak rigid), weak Armendariz ring. On the assumption that the factor ring R/I is weak Armendariz, where I is nilpotent ideal, we prove that R is a weak Armendariz ring.
