A simple algorithmically reasoned characterization of wait-free computation (extended abstract)

Elizabeth Borowsky, Eli Gafni
1997 Proceedings of the sixteenth annual ACM symposium on Principles of distributed computing - PODC '97  
The second tool is an iterated explicit simple convergence algorithm. In the Ph.D. Thesis oft he first author these tool were used to characterize models more complex than read-write shared-memory.  ...  This paper introduces two new novel tools for the study of distributed computing and shows their utility by using them to exhibit a simple derivation of the Herlihy and Shavit characterization of wait-free  ...  Once we have a characterization of the model on our hands, it is natural to ask how its waitfree solvability power relates to the power of the standard shared-memory model, It is easy to see that any task  ...

Introduction to the model of hierarchical complexity

Michael Lamport Commons
2007 Behavioral Development Bulletin  
The participant's performance on a task of a given complexity represents the stage of developmental complexity.  ...  The Model of Hierarchical Complexity presents a framework for scoring reasoning stages in any domain as well as in any cross cultural setting.  ...  For this reason, the Model characterizes all stages as hard and distinct. The orders of hierarchical complexity are stepped like the rings around the nucleus.  ...

Hierarchical Complexity of Tasks Shows the Existence of Developmental Stages

Michael Lamport Commons, Edward James Trudeau, Sharon Anne Stein, Francis Asbury Richards, Sharon R. Krause
1998 Developmental Review  
The resultant definition of stage is that it is the highest order of hierarchical complexity on which there is successful task performance.  ...  The major purpose of this paper is to introduce the notion of the order of hierarchical complexity of tasks.  ...  People's highest stage response characterizes the most hierarchically complex task they solve.  ...

Characterizing the Involvement of Rostrolateral Prefrontal Cortex in Prospective Memory

M. T. Rubens, T. P. Zanto
2011 Journal of Neuroscience  
Little empirical work has aimed at specifying which processing stage or stages (i.e., encoding, maintaining, or retrieving delayed intentions) depend upon the engagement of RLPFC regions during PM tasks  ...  To identify brain regions involved in each processing stage of the task, PM trials were contrasted against baseline trials in a whole-brain univariate analysis.  ...

From multistage information-seeking models to multistage search systems

Hugo C. Huurdeman, Jaap Kamps
2014 Proceedings of the 5th Information Interaction in Context Symposium on - IIiX '14  
A multitude of models of the information seeking process, for example Kuhlthau's ISP model, divide the information seeking process for complex search tasks into multiple stages.  ...  To find ways to reduce the gap, we look at existing models of the information seeking process, at search interfaces supporting complex search tasks, and at the use of interface features over time.  ...  Acknowledgments We are very grateful to Vu Tran and the Information Engineering Group at the University of Duisburg-Essen for allowing us to analyze data collected with the ezDL interface.  ...
