I consider phenomenological changes in the standard solar model with the goal of testing recent claims that the solar neutrino puzzle requires new particle physics. The assumption of a steady-state sun producing the correct luminosity and governed by standard microphysics appears to leave only one nonstandard solar model possibility open, slow mixing of the solar core on timescales characterist...

Researchers investigated the effects of a read-aloud modification on students' performance on a reading comprehension test. A total of 338 students in Grades 4 and 5 participated; 76 of these students (22%) received special education services, the majority of whom were labeled learning disabled. Students completed a standardized reading comprehension test under two conditions: (a) standard admi...

In this review talk I cover some recent developments in understanding the role that magnetic fields play in cataclysmic variables. I discuss the recent DNO–QPO unification models; the disk–magnetosphere boundary; some issues concerning the soft blackbody component and the nature of the X-ray spectra in MCVs; whether the SW Sex stars are magnetic, and finally I mention the weird behavior of FS A...

This paper reports on a pilot study that is concerned with the cognitive aspects of reading in an electronic environment. The study focuses on text based electronic documents. A cognitive model for hypertext document reading proposed in an earlier work is here developed and validated with the use of think aloud protocols. The model is concerned with the general cognitive processes that take pla...

Some theorists argue that the node-link design of the Web mimics human information storage and that Web use encourages individuals to process information efficiently and effectively, potentially increasing meaningful learning. However, critics claim that Web navigation increases cognitive load and often produces disorientation. This reduces the processing devoted to meaningful learning, and, th...

Collective decision making is the process of mapping the individual views of several individual agents into a joint decision. The need for collective decision making mechanisms is abundant, not just in the realm of politics, but also for a wide range of scientific and technological applications. These include, for instance, logistics, grid computing, and recommender systems. The alternatives to...

The concept of a program in answer set programming is constantly evolving as additional constructs are being added to the basic syntax used in the original definition of a stable model: second negation, disjunction and negation in heads of rules, choice rules, cardinality constraints and other aggregates. The future may bring us new extensions, motivated both by applications of ASP and by consi...

In a recent paper, Albrecht Kyrieleis, Jeff Forshaw and I discovered a new tower of super-leading logarithms in gaps between jets cross sections. After discussions with the referee of our paper and further investigation, we have come to view this as a breakdown of naive coherence for initial state radiation. In this talk I illustrate this statement in a simple way, and show how it results in th...

Much of what we know about speech perception comes from laboratory studies with clean, canonical speech, ideal listeners and artificial tasks. But how do interlocutors manage to communicate effectively in the seemingly less-than-ideal conditions of everyday listening, which frequently involve trying to make sense of speech while listening in a non-native language, or in the presence of competin...

Over the past several years, we have seen an explosion in the number of tools and services that enable scholars to improve their personal productivity whether it is socially enabled reference managers or cloud-hosted experimental environments. However, we have yet to see a step-change in the productivity of the system of scholarship as a whole. While there are certainly broader social reasons f...
