introduction: the effects of accidents vary from minor injuries to fatalities and from insignificant damage to very severe damage to the environment and property. in order to prevent accidents in the work place, the root causes of and events should be identified using a systematic method and the results should be published. the current study aims to investigate the given causes of an accident i...

The abstract aims to connect various fields of knowledge, including journalism, information sciences, and human cognition. It analyzes Recommendation Systems (RS) on the Web in order to understand how they are changing user-experiences and, consequently, affecting the fundamental structures of journalism. Today’s networks are decentralized with few barriers to entry. They provide new ways of co...

In this paper, I illustrate the importance of both dynamics and network constraints in the group formation process. I introduce a class of games called sequential group formation games, in which players make their group membership decisions sequentially over time, and show that the dynamics act as an equilibrium refinement. However, the resulting equilibrium is highly suboptimal–groups tend to ...

Due to the asymmetric nature of the nucleotides, the extant informational biomolecule, DNA, is constrained to replicate unidirectionally on a template. As a product of molecular evolution that sought to maximize replicative potential, DNA's unidirectional replication poses a mystery since symmetric bidirectional self-replicators obviously would replicate faster than unidirectional self-replicat...
