For many years, people have wanted to share single-user applications. The vision has been to replicate instances of a single-user application throughout the network and transmit input events from one instance to the others. While there have been attempts to build such a system, they have not succeeded due to an implicit assumption of application determinism. This assumption is untrue in the fac...

Using a controlled experiment, we examine the role of nurture in explaining the stylized fact that women shy away from competition. Our subjects (students just under 15 years of age) attend publicly-funded single-sex and coeducational schools. We …nd robust di¤erences between the competitive choices of girls from single-sex and coed schools. Moreover, girls from single-sex schools behave more l...

Choosing to Compete: How Different Are Girls and Boys? Using a controlled experiment, we examine the role of nurture in explaining the stylized fact that women shy away from competition. Our subjects (students just under 15 years of age) attend publicly-funded single-sex and coeducational schools. We find robust differences between the competitive choices of girls from single-sex and coed schoo...

The purpose of this paper* is to axiomatize two 4-valued propositional logics suggested by Herzberger in [l], section VI. They are of philosophical interest because their interpretation makes use of two ideas inspired by Jean Buridan: (1) a proposition may correspond to the world and yet be untrue because it is semantically deviant, and (2) logically valid arguments preserve correspondence with...

Multilayer perceptrons are often trained using error backpropagation (BP). BP training can be done in either a batch or continuous manner. Claims have frequently been made that batch training is faster and/or more "correct" than continuous training because it uses a better approximation of the true gradient for its weight updates. These claims are often supported by empirical evidence on very s...

Hierarchical latent class (HLC) models generalize latent class models. As models for cluster analysis, they suit more applications than the latter because they relax the often untrue conditional independence assumption. They also facilitate the discovery of latent causal structures and the induction of probabilistic models that capture complex dependencies and yet have low inferential complexit...

Elementary results concerning the connections between deductive relations and probabilistic support are given. These are used to show that Popper-Miller's result is a special case of a more general result, and that their result is not \very unexpected" as claimed. According to Popper-Miller, a purely inductively supports b only if they are \deductively independent"|but this means that :a ` b. H...

It is widely believed that low-level languages with jumps must be difficult to reason about by being inherently non-modular. We have recently argued that this in untrue and proposed a novel method for developing compositional natural semantics and Hoare logics for low-level languages and demonstrated its viability on the example of a simple low-level language with expressions (Saabas & Uustalu ...

We use 118 H$\beta$ quasar (QSO) observations in the redshift range $0.0023 \leq z 0.89$ to simultaneously constrain cosmological model parameters and QSO 2-parameter radius-luminosity ($R-L$) relation six different models. find that $R-L$ for these QSOs are independent of assumed cosmology so seem be standardizable through (although there is a complication might render this untrue). Cosmologic...
