We investigated how human observers estimate an object's three-dimensional (3D) motion trajectory during visually guided self-motion. Observers performed a task in an immersive virtual reality system consisting of front, left, right, and floor screens of a room-sized cube. In one experiment, we found that the presence of an optic flow simulating forward self-motion in the background induces a w...

Little is known about mechanisms mediating a stable perception of the world during pursuit eye movements. Here, we used fMRI to determine to what extent human motion-responsive areas integrate planar retinal motion with nonretinal eye movement signals in order to discard self-induced planar retinal motion and to respond to objective ("real") motion. In contrast to other areas, V3A lacked respon...

This article reviews the change from a one-person to a two-person psychology in psychoanalysis. In particular, Robert Stolorow's intersubjectivity theory is presented and then contrasted with the client-centered approach to therapy. It is concluded that contemporary clientcentered therapy is a two-person psychology, and that well-trained clientcentered therapists do reflect on their own subject...

Article history: Received 17 April 2012 Available online 27 September 2012 Self-determination theory (SDT) posits the existence of distinct types of motivation (i.e., external, introjected, identified, integrated, and intrinsic). Research on these different types of motivation has typically adopted a variable-centered approach that seeks to understand how each motivation in isolation relates to...

With the recent technological advances, biological datasets, often represented by networks (i.e., graphs) of interacting entities, proliferate with unprecedented complexity and heterogeneity. Although modern network science opens new frontiers analyzing connectivity patterns in such we still lack data-driven methods for extracting an integral connectional fingerprint a multi-view graph populati...

Although the “scale-free” literature is large and growing, it gives neither a precise definition of scale-free graphs nor rigorous proofs of many of their claimed properties. In fact, it is easily shown that the existing theory has many inherent contradictions and verifiably false claims. In this paper, we propose a new, mathematically precise, and structural definition of the extent to which a...

Abstract. A graph is an {r, s}-graph if the set of degrees of their vertices is {r, s}. A clique of a graph is a maximal complete subgraph. The clique graph K(G) of a graph G is the intersection graph of all its cliques. A graph G is self-clique if G is isomorphic to K(G). We show the existence of self-clique {5, 6}-graphs whose cliques are all triangles, thus solving a problem posed by Chia an...

for an arbitrary ring $r$, the zero-divisor graph of $r$, denoted by $gamma (r)$, is an undirected simple graph that its vertices are all nonzero zero-divisors of $r$ in which any two vertices $x$ and $y$ are adjacent if and only if either $xy=0$ or $yx=0$. it is well-known that for any commutative ring $r$, $gamma (r) cong gamma (t(r))$ where $t(r)$ is the (total) quotient ring of $r$. in this...

Background Chronic nature of thalassemia causes changes in different aspects of life in patients, including their self-efficacy. The aim of this study was to determine the effect of family-centered empowerment program on the self-efficacy of adolescents with Thalassemia major. Methods A quasi-experimental study was performed on adolescents with thalassemia major in 2013 in Bandar Abbas, Iran....
