This research is first focussed investigation examine effects dress formality on ‘big two’ impression formation, perceptions warmth and competence.

In recent years, social entrepreneurship has received an increasing attention from the academic community. Social is a topic related to various areas such as economics, management, education, sociology, psychology, and it not surprising that issues are always debated with definitions, methods, approaches. This study aims establish networks maps in based on systematic review of 1361 publications...

In this paper we compute some of the higher order terms in the asymptotic behavior of the two point function P(A2(0)≤ s1,A2(t)≤ s2), extending the previous work of Adler and van Moerbeke (arXiv:math.PR/0302329; Ann. Probab. 33, 1326–1361, 2005) and Widom (J. Stat. Phys. 115, 1129–1134, 2004). We prove that it is possible to represent any order asymptotic approximation as a polynomial and integr...

This paper deals with the question of existence of periodic solutions of nonautonomous predator–prey dynamical systems with Beddington–DeAngelis functional response. We explore the periodicity of this system on time scales. New sufficient conditions are derived for the existence of periodic solutions. These conditions extend previous results presented in [M. Bohner, M. Fan, J. Zhang, Existence ...
