Pseudo Ricci symmetric real hypersurfaces of a complex projective space are classified and it is proved that there are no pseudo Ricci symmetric real hypersurfaces of the complex projective space CPn for which the vector field ξ from the almost contact metric structure (φ, ξ, η, g) is a principal curvature vector field.

Let ~ be a (possibly infinite) projective plane, and G a collineation group of ~ . Suppose temporarily that ~ is a translation plane with respect to L, and G is the group of collineations fixing L. Then G=TGx, where T is the translation group with respect to L, and x is an affine point. If, moreover, the characteristic of ~ is not 2, then Gx= CG(t) and G= TCa(t), where t is an involutory homolo...

a projective parameter of a geodesic as solution of certain ode is defined to be a parameter which is invariant under projective change of metric. using projective parameter and poincaré metric, an intrinsic projectively invariant pseudo-distance can be constructed. in the present work, solutions of the above ode are characterized with respect to the sign of parallel ricci tensor on a finsler s...

pseudo ricci symmetric real hypersurfaces of a complex projective space are classified and it is proved that there are no pseudo ricci symmetric real hypersurfaces of the complex projective space cpn for which the vector field ξ from the almost contact metric structure (φ, ξ, η, g) is a principal curvature vector field.

the triple factorization of a group $g$ has been studied recently showing that $g=aba$ for some proper subgroups $a$ and $b$ of $g$, the definition of rank-two geometry and rank-two coset geometry which is closely related to the triple factorization was defined and calculated for abelian groups. in this paper we study two infinite classes of non-abelian finite groups $d_{2n}$ and $psl(2,2^{n})$...

BACKGROUND Studies on popular names of birds help to understand the relationship between human beings and birds and it also contributes to the field of ornithology. METHODS This study aims to register the ethnotaxonomy of birds in the village of Pedra Branca, Santa Teresinha municipality, Bahia State, Brazil, by cataloguing and identifying their popular names, besides understanding the ethnoc...

In 3 studies, we document various properties of perceiver effects--or how an individual generally tends to describe other people in a population. First, we document that perceiver effects have consistent relationships with dispositional characteristics of the perceiver, ranging from self-reported personality traits and academic performance to well-being and measures of personality disorders, to...

The current study tested the hypothesis that mothers who have experienced child maltreatment and aggression within their adult relationships may be at particular risk for misinterpreting infant emotions, leading to less sensitive parenting behaviors. Participants were 120 pregnant women recruited for a larger, longitudinal study investigating the role of psychosocial and environmental risk on w...

Projective tests are considered to uncover unconscious emotions while avoiding psychological resistance. However, the results of projective tests may be affected by conscious emotions. This study investigates whether self-disclosure, which is a conscious factor, affected the results of a sentence completion test (SCT), which is a projective test. Eighty-five university students completed a ques...
