Educational inequality is one of the types of inequality which always pervades on an educational system. The existence of the educational inequality alongside other inequalities and their interaction are the most important in a society. This paper attempts to examine the factors that affect educational inequality in Kazeroon city. The method of present study is survey and data collection tool i...

objective : identification of the risk factors and psychological correlates of prolonged grief disorder is vital for health promotions in relatives of persons who died of cancer. the aim of this research was to investigate the role of defense mechanisms, character dimension of personality and demographic factors on complicated grief following a loss of a family member to cancer. method : a numb...

Under certain conditions the ‘singular value function’ formula gives the Hausdorff dimension of self-affine fractals for almost all parameters in a family. We show that the size of the set of exceptional parameters is small both in the sense of Hausdorff dimension and Fourier dimension.

In this paper, we show that the density of the one-inclusion hypergraph induced by a family of multi-valued functions is bounded by the pseudo-dimension of this family. (The original proof for this fact, that has been published quite recently, makes use of a wrong claim.) We show furthermore that the well-known graph-dimension is another upper bound on the density (which solves an open problem ...

A notion of dimensional dual polar spaces of polar type is given with a family of new examples. Nonexistence is shown for those of dimension 3, while there are just two isomorphism classes for those of dimension 2.

Multistability is characterized by the occurrence of multiple coexisting attractors. We introduce a family of maps that possess this property and in particular exhibits coexisting chaotic attractors. In this family not only the maps’ parameters can be varied but also their dimension. So, four types of multistable attractors, equilibria, periodic orbits, quasi-periodic orbits and chaotic attract...

Intergenerational solidarity is and important phenomenon for strengthening  social cohesion and is an important immediate mechanism that has major role in the transfer of knowledge from generation to generation. But the distance between parents and youth, among generations, and this gap exists between the social system, with profound social problems facing the generation gap in the process in t...

We show that the family of spectral triples for quantum projective spaces introduced by D’Andrea and Da̧browski, which have spectral dimension equal to zero, can be reconsidered as modular spectral triples by taking into account the action of the element K2ρ or its inverse. The spectral dimension computed in this sense coincides with the dimension of the classical projective spaces. The connecti...
