Purpose: The aim of this study was to compare the effectiveness of family therapy program based on attachment and emotion on anxiety disorder and behavior of gifted adolescents. Methodology: The research method was quasi-experimental with pretest-posttest design with two experimental groups. From the statistical population of students studying in gifted schools in Tehran, 40 people were random...

I derive a simple condition for the existence of a stable invariant distribution of an increasing Markov process on a non-compact state space. I use this condition in two workhorse models in macroeconomics. First, I settle a conjecture of Carroll by characterizing the conditions under which the canonical bu¤er stock saving model has a stable invariant distribution. Second, I show that in the Br...

Gravitational search algorithm (GSA) is one of the newest swarm based optimization algorithms, which has been inspired by the Newtonian laws of gravity and motion. GSA has empirically shown to be an efficient and robust stochastic search algorithm. Since introducing GSA a convergence analysis of this algorithm has not yet been developed. This paper introduces the first attempt to a formal conve...

We discuss stability of spherically symmetric static solutions in Newtonian limit of Jordan, Brans-Dicke field equations. The behavior of the stable equilibrium solutions for the spherically symmetric configurations considered here, it emerges that the more compact a model is, the more stable it is. Moreover, linear stability analysis shows the existence of stable configurations for any polytro...

It is well-known that not all instances of the stable roommates problem admit a stable matching. Here we establish the first nontrivial upper bound on the limiting behavior of P,,, the probability that a random roommates instance of size n has a stable matching, namely, limn-P,, I el% (=0.8244. . .).

a detailed study of ostracoda changes against the stable isotopes of carbon and oxygen acrossthe cenomanian-turonian boundary mass extinction has been fully documented in one section, the south ofengland. this section comprises the uppermost cenomanian to lowermost turonian strata. the comparisonbetween the results obtained in this research and two rival models for the cenomanian-turonian bound...

This study investigated the role of trust beliefs (i.e., trustworthiness, trustfulness) on aggression trajectories in a four-wave longitudinal study using an ethnically diverse sample of 8- to 11-year-old children (N = 1,028), as well as the risk profiles of low trust beliefs and low socioeconomic status on aggression trajectories. At Time 1 to Time 4, teachers provided ratings of overt aggress...
