Previous studies about the effects of social rejection on individuals' social behaviors have produced mixed results and tend to study mating behaviors from a static point of view. However, mate selection in essence is a dynamic process, and therefore sociometer theory opens up a new perspective for studying mating and its underlying practices. Based on this theory and using self-perceived mate ...

The present study examined the predictive value of filial piety and parental involvement with respect to students’ academic behavior — orientation of achievement motivation and amotivation. Parental involvement was defined as the parents’ expectation, value on education and feedback perceived by the students. This study was conducted in Hong Kong by gathering data from a questionnaire survey at...

We study the stability of a spherically symmetric black hole with a global monopole hair. Asymptotically the spacetime is flat but has a deficit solid angle which depends on the vacuum expectation value of the scalar field. When the vacuum expectation value is larger than a certain critical value, this spacetime has a cosmological event horizon. We investigate the stability of these solutions a...

In this paper we consider two ways to generalize the mathematical expectation of a random variable, the Choquet expectation and Peng’s g-expectation. An open question has been, after making suitable restrictions to the class of random variables acted on by the Choquet expectation, for what class of expectation do these two definitions coincide? In this paper we provide a necessary and sufficien...

(where E[·] denotes expectation), or, equivalently, as the difference between the probability that the two X,Y –pairs are concordant and the probability that the two X,Y –pairs are discordant. A pair of X,Y –pairs is said to be concordant if the larger X–value is paired with the larger Y –value, and is said to be discordant if the larger X–value is paired with the smaller Y –value. Somers’ D of...

The fermionic condensate and vacuum expectation value of the energy-momentum tensor, for a massive fermionic field on the background of anti-de Sitter spacetime, in the geometry of two parallel boundaries with bag boundary conditions, are investigated. Vacuum expectation values, expressed as series involving the eigenvalues of the radial quantum number, are neatly decomposed into boundary-free,...

Purpose – The research analyzed the determinants (Performance Expectation, Expectation of Effort, Social Influence, Facilitating Conditions, Hedonic Motivation, Value and Habit) intention behavior using online discount coupons, through UTAUT2 in Brazilian context. Design/methodology/approach survey was adopted with an instrument adapted from Yang (2010) Christino et al. (2019) validated by expe...
