Hundred Years of Teacher Training in Iran: Opportunities, Threats, and Future Outlook   A. Saafi*   The history of formal education in Iran shows that teacher training, in its contemporary meaning, started in 1918 when the first center for training male teachers (Daarolmo’allemin) along with Daarolmo’allemaat for female teachers was established. During the past one hundred years tremendous ...

In today’s world online social network (OSNs) are exclusive social and web portent affecting perceptions and behaviours of their users and helping them to maintain/create social presence. It is remarkable to analyze the growth and evolution of online social networks where either we consider the marketing strategy or new services being offered, also from a scientific viewpoint, since their erect...

Industrial challenges in product line evolution suggest a flexible and iterative approach that integrates domain and application engineering activities. We present our ongoing and planned research addressing the evolution of model-based product lines. In particular, we propose an iterative process and initial tool support for product line evolution. Our work is based on an analysis of industria...

Observations have evidenced that passively evolving massive galaxies at high redshift are much more compact than local galaxies with the same stellar mass. We argue that the observed strong evolution in size is directly related to the quasar feedback, which removes huge amounts of cold gas from the central regions in a Salpeter time, inducing an expansion of the stellar distribution. The new eq...

A fundamental ambition of Grid and distributed systems is to be capable of sustaining evolution and allowing for adaptability [1, 2]. Furthermore, as the complexity and sophistication of theses structures increases, so does the need for adaptability of each component. One of the primary benefits of Service Oriented Architecture (SOA) is the ability to compose applications, processes or more com...

Early-type galaxies are characterized by many scaling relations. Evolutionary classifications find that some of these correlations are indeed generated by diversification. With a simple mathematical formalism, we show (Fraix-Burnet 2011) that even the so-called fundamental plane, a relatively tight correlation between three variables, can be easily explained as the artifact of the effect of ano...

The slow evolution of the M/L ratios, colors, and line strengths of cluster early-type galaxies to z ∼ 1 suggests that their stars were formed at very high redshift. At the same time, morphological studies of distant clusters indicate significant evolution in the early-type galaxy population. Striking evidence for strong morphological evolution in clusters is the discovery of a large number of ...
