以随迁儿童为被试，通过操纵其消极元刻板印象，探讨了元刻板印象威胁对攻击行为的影响及其作用机制。结果显示：(1)元刻板印象威胁能够引起个体攻击水平的升高；(2)挫折感在元刻板印象威胁与攻击行为(针对城市儿童)之间起部分中介作用；(3)使用想象群际接触策略控制挫折感水平，结果发现元刻板印象威胁对攻击行为(针对城市儿童)的效应随着挫折感的降低而减弱，进一步支持了挫折感的中介作用。总之，研究证明元刻板印象威胁会导致随迁儿童的挫折感水平升高，从而诱发更多的攻击行为。 |

In this paper, we investigate related properties of some particular derivations and give some characterizations of additive derivations in MV-algebras. Then, we obtainthat the #12;xed point set of additive derivations is still an MV-algebra. Also,we study Boolean additive derivations and their adjoint derivations. In particular, we get that the #12;xed point set of Boolean addition derivations and that of their adjoint derivations are isomorphism. Moreover, we prove that every MV-algebra is isomorphic to the direct product of the #12;xed point set of Boolean additive derivations and that of their adjoint derivations. Finally, we show that the structure of a Boolean algebra is completely determined by its set of all Boolean additive (implicative) derivations. |

The main goal of this paper is to investigate (strong) monadic NM-algebras and to prove the (chain) completeness of the monadic NM-logic. In this paper, we introduce monadic NM-algebras: a variety of NM-algebras equipped with universal quanti#12;ers. Also, we study some properties of them and obtain some conditions under which a monadic NM-algebra becomes a monadic Boolean algebra. Besides, we show that the variety of NM-algebras are the equivalent algebraic semantics of the monadic fragment of NM predicate logic. Furthermore, we discuss relations between monadic NM-algebras and some related structures, likeness modal NMalgebras and rough approximation spaces. In addition, we introduce and investigate monadic #12;lters in monadic NM-algebras. In particular, by using monadic #12;lters on monadic NM-algebras, we characterize two kinds of monadic NM-algebras, which are simple and subdirectly irreducible. Moreover, we focus on a monadic analogous of representation theorem for NM-algebras and obtain that every strong monadic NM-algebra can be represented as subalgebras of products of linearly ordered ones. Then, we present monadic NM-logic, a system of many-valued logic capturing the tautologies of the predicate logics of nilpotent minimum t-norm and it's residua. As an application of (strong) monadic NM-algebras, we prove the (chain)completeness of monadic NM-logic. Our results constitute a crucial #12;rst step for providing a solid algebraic foundation for the one element fragment of NM predicate logic. |
