Identity process theory : identity, social action and social change
\"We live in an ever-changing social world, which constantly demands adjustment to our identities and actions. Advances in science, technology and medicine, political upheaval, and economic development are just some examples of social change that can impact upon how we live our lives, how we view ourselves and each other, and how we communicate. Three decades after its first appearance, identity process theory remains a vibrant and useful integrative framework in which identity, social action and social change can be collectively examined. This book presents some of the key developments in this area. In eighteen chapters by world-renowned social psychologists, the reader is introduced to the major social psychological debates about the construction and protection of identity in face of social change. Contributors address a wide range of contemporary topics - national identity, risk, prejudice, intractable conflict and ageing - which are examined from the perspective of identity process theory\"-- Provided by publisher.

Weak G-identities for the Pair (M2(C),sl2(C))
In this paper we study algebras acted on by a finite group G and the corresponding G-identities. Let M2(C) be the 2×2 matrix algebra over the field of complex numbers C and let sl2(C) be the Lie algebra of traceless matrices in M2(C). Assume that G is a finite group acting as a group of automorphisms on M2(C). These groups were described in the Nineteenth century, they consist of the finite subgroups of PGL2(C), which are, up to conjugacy, the cyclic groups Zn, the dihedral groups Dn (of order 2n), the alternating groups A4 and A5, and the symmetric group S4. The G-identities for M2(C) were described by Berele. The finite groups acting on sl2(C) are the same as those acting on M2(C). The G-identities for the Lie algebra of the traceless sl2(C) were obtained by Mortari and by the second author. We study the weak G-identities of the pair (M2(C),sl2(C)), when G is a finite group. Since every automorphism of the pair is an automorphism for M2(C), it follows from this that G is one of the groups above. In this paper we obtain bases of the weak G-identities for the pair (M2(C),sl2(C)) when G is a finite group acting as a group of automorphisms.

On simplicity of intermediate -algebras
We prove simplicity of all intermediate$C^{\\ast }$-algebras$C_{r}^{\\ast }(\\unicode[STIX]{x1D6E4})\\subseteq {\\mathcal{B}}\\subseteq \\unicode[STIX]{x1D6E4}\\ltimes _{r}C(X)$in the case of minimal actions of$C^{\\ast }$-simple groups$\\unicode[STIX]{x1D6E4}$on compact spaces$X$. For this, we use the notion of stationary states, recently introduced by Hartman and Kalantar [Stationary$C^{\\ast }$-dynamical systems. Preprint , 2017, arXiv:1712.10133 ]. We show that the Powers’ averaging property holds for the reduced crossed product$\\unicode[STIX]{x1D6E4}\\ltimes _{r}{\\mathcal{A}}$for any action$\\unicode[STIX]{x1D6E4}\\curvearrowright {\\mathcal{A}}$of a$C^{\\ast }$-simple group$\\unicode[STIX]{x1D6E4}$on a unital$C^{\\ast }$-algebra${\\mathcal{A}}$, and use it to prove a one-to-one correspondence between stationary states on${\\mathcal{A}}$and those on$\\unicode[STIX]{x1D6E4}\\ltimes _{r}{\\mathcal{A}}$.

Center group actions and related concepts
In order to examine the characteristics of center group spaces, center orbits, center stabilizers, and center kernels, the major purpose of this work is to introduce the definition of center group actions. We review the definition and proposition of the center limit set, as well as the center thin sets (briefly

-spaces (briefly
