Model a network as an edge-weighted graph, where the (unknown) weight we of edge e indicates the frequency of observed interactions, and over time t we observe a Poisson(twe) number of interactions across edges e. How should we estimate some given statistic of the underlying network? This leads to wide-ranging and challenging problems, on which this article makes only partial progress.

In political scientists’ drive to examine causal mechanisms, qualitative expert interviews have an important role play. This is particularly true for the analysis of complex decision-making processes, where there a dearth data, and linking macro micro levels analysis. The paper offers suggestions making most effective reflective use interviews. It advocates encompassing, knowledge-based underst...

With visual analytical tools becoming more sophisticated and prevalent in the analysis communities, it is now apparent that understanding how analysts utilize these tools is more important than ever. Such understanding can lead to improving the tools, but a more subtle and equally important aspect lies in the discovery of the analysts’ reasoning process for solving complex problems through the ...

The title of my talk, “Living Neoplatonism,” is intentionally ambiguous, for it can refer, first, to Neoplatonism as a living philosophy rather than as a historical artifact embodied in the writings of Plotinus, Proclus, and the rest. And second, it can refer to the practice of living Neoplatonically as a modern way of life. But why Neoplatonism, as opposed to some other philosophy? From my per...

after passing more than one decade of appearance of digital libraries in iran, they couldn’t meet their real mission, which is responding to audience needs. surely, this problem is affected by potentially and real factors. so this research wants to recognize resistant factors and driving factors by recourse oriented approach, and then to fit them in integrated model.research method which we app...

Probabilistic algorithms o er a means of computing that works with the grain of analogue hardware, rather than against it. This paper proposes the use of such an algorithm in applications where the advantages of analogue hardware are most likely to be realised.
