On Exceptions Versus Continuations in the Presence of State [chapter]

Hayo Thielecke
2000 Lecture Notes in Computer Science  
We compare the expressive power of exceptions and continuations when added to a language with local state in the setting of operational semantics.  ...  Continuations are shown to be more expressive than exceptions because they can cause a function call to return more than once, whereas exceptions only allow discarding part of the calling context.  ...  On Exceptions Versus Continuations in the Presence of State  ...

How Immersive Is Enough? A Meta-Analysis of the Effect of Immersive Technology on User Presence

James J. Cummings, Jeremy N. Bailenson
2015 Media Psychology  
The concept of presence, or "being there" is a frequently emphasized factor in immersive mediated environments.  ...  To investigate this assumption the current metaanalysis synthesizes decades of empirical research examining the effect of immersive system technology on user experiences of presence.  ...  Most notably, the effect of tracking level on user presence was found to be significantly larger than that of nearly all other immersive features (with the exceptions being the effects of update rate and  ...

The role of wood anatomy in phylogeny reconstruction of Ericales

Frederic Lens, Jürg Schönenberger, Pieter Baas, Steven Jansen, Erik Smets
2007 Cladistics  
However, when pedomorphic character states are coded as inapplicable, the combined bootstrap topology results in an increase of resolution and support at most deeper nodes compared with the molecular analyses  ...  Based on the morphology of vessels and fibers, and the distribution of axial parenchyma, two major wood types can be distinguished within Ericales: (i) a "primitive" type, nearly identical to the wood  ...  Acknowledgments We thank Helga Ochoterena (UNAM) and Peter Hovenkamp (NHN-Leiden) for their useful comments on the paper.  ...

2020 Journal of Experimental Biology  
We conducted at-sea experiments to contrast the effects of navy PAS vs. CAS on sperm whale behaviour using animal-attached sound and movement-recording tags (n=16 individuals) in Norway.  ...  We discuss the importance of exposure context and need to measure cumulative sound energy to account for intermittent vs. more continuous sources in noise impact assessments.  ...  Charlotte Curéand Peter Tyack provided valuable feedback on the study design. We would like to thank 3S partners and funders for enabling this research.  ...
