Identity Strategies of Muslim Meskhetians （Meskhetian turks） in Cultural Context

This study examines how the process of relocating has influenced on the strategy of identity of Muslim Meskhetians, the unique group from Georgia whit experiences of multiple forced migrations and displacements in the 20th and 21st century. In the 40s of 20th century, as a result of Stalin＇s policy to clean the southern border of the Soviet Union from the ＂undesirable peoples＂, the Muslim population, primordially comprised of the Turkish-speaking Meskhetians, was deported from the Caucasus to the Central Asian republic of Soviet Union. The violent clashes in the Fergana Valley, Uzbekistan in 1989, Muslim Meskhetians have fled to Russia. After the fall of the Soviet Union in 1991, they lived in Russian Federation during 20 years without citizenship and any right. In 2005, the United States government granted refugee status to Muslim Meskhetians, and they moved to the USA. We combined the in-depth interviews with the immigrants, who live in the states of Pennsylvania and Illinois State of the USA, to illustrate the changes and effects of the relocation on the Muslim Meskhetian strategies of identity. Drawing upon theoretical conceptualizations of socialization and identity strategies of C. Camilleri, this study finds that Muslim Meskhetian immigrants are carefully negotiating strategy of identity in the face of displacement.

Annihilator on Co-commutators with Derivations on Lie Ideals in Prime Rings

Let R be a prime ring of characteristic different from 2, d and 9 two derivations of R at least one of which is nonzero, L a non-central Lie ideal of R, and a ∈ R. We prove that if a（d（u）u - ug（u）） = 0 for any u ∈ L, then either a = O, or R is an sa-ring, d（x） = [p, x], and g（x） = -d（x） for some p in the Martindale quotient ring of R.

Generalized Differential Identities of (Semi-)Prime Rings

Let R be a semiprime ring with characteristic p≥0 and RF be its left Martindale quotient ring. If ф（Xi^△j） is a reduced generalized differential identity for an essential ideal of R, then ф（Zije（△j ）） is a generalized polynomial identity for RF, where e（△j） are idempotents in the extended centroid of R determined by △j. Let R be a prime ring and Q be its symmetric Martindale quotient ring. If ф（Xi△j） is a reduced generalized differential identity for a noncommutative Lie ideal of R, then ф（Zij） is a generalized polynomial identity for [R, R]. Moreover, if ф（Xi△j） is a reduced generalized differential identity, with coefficients in Q, for a large right ideal of R, then ф（Zij） is a generalized polynomial identity for Q.

STURM COMPARISON THEOREM OF SOLUTION FOR SECOND ORDER NONLINEAR DIFFERENTIAL EQUATIONS

In this paper, we establish some differential identities and obtain some Sturm comparison theorems for the second order nonlinear differential equation by using them.and generalize some classicial Sturm comparison theorems.

Generalized Derivations as Jordan Homomorphisms on Lie Ideals and Right Ideals

Let R be a prime ring, L a non-central Lie ideal of R and g a non-zero generalized derivation of R. If g acts as a Jordan homomorphism on L, then either g（x） = x for all x ∈ R, or char（R） = 2, R satisfies the standard identity s4（x1, x2, x3, x4）, L is commutative and u2 ∈ Z（R）, for any u C L. We also examine some consequences of this result related to generalized derivations which act as Jordan homomorphisms on the set [I, I], where I is a non-zero right ideal of R.
