Mitochondrial 12S rRNA sequence data were used to examine the taxonomic status of the endemic brown, Auckland Island, and Campbell Island teal. Based on phylogenetic reconstructions using the 12S rRNA data we have found that the Great Barrier Island brown teal, and the Auckland and Campbell Island teals form a discrete clade, to the exclusion of the Fiordland brown teal. All of the Fiordland br...

Classification evaluation metrics are often used to evaluate adaptive tutoring systems— programs that teach and adapt to humans. Unfortunately, evidence suggests that existing convention for evaluating tutoring systems may lead to suboptimal decisions. In a companion paper, we propose Teal, a new framework to evaluate adaptive tutoring. In this paper we propose an alternative formulation of Tea...

Hybridization is common between species of animals, particularly in waterfowl (Anatidae). One factor shown to promote hybridization is restricted mate choice, which can occur when 2 species occur in sympatry but one is rare. According to the Hubbs principle, or "desperation hypothesis," the rarer species is more likely to mate with heterospecifics. We report the second of 2 independent examples...

ion Layer of a database system. TEAL is an implementation of a framework for secure storage and resides inside Abstraction Layer of a database (DBAL). We demonstrate how TEAL integrates transparently into existing applications. Furthermore, we explain query processing on encrypted data by re-using components of the DBAL. Finally, we visualize the impact of the processing steps of TEAL on the ru...

Abstract ‘ Orange & Teal ’ has become the preferred ‘look’ of Hollywood movie industry. Is this craze just another arbitrary fashion? Possibly not, because ‒ apart from name palette been around for ages in visual arts. It is variously known as ‘painting cool and warm,’ drawing a trois croyons , use ‘limited palette,’ so forth. This leaves open question whether there might be one or more fun...

Introduction O ver the last three years, the MIT Physics Department has been introducing major changes in the way that 8.02, Electromagnetism I, is taught at the Institute, through the TEAL (Technology Enhanced Active Learning) Project [Supported by the d'Arbeloff Fund for Excellence in MIT Education, the MIT/Microsoft iCampus Alliance, the MIT School of Science, and NSF] (Belcher 2001). After ...

This chapter describes learning electromagnetism with visualizations and focuses on the value of concrete and visual representations in teaching abstract concepts. We start with a theoretical background consisting of three subsections: visualization in science, simulations and microcomputer-based laboratory, and studies that investigated the effectiveness of simulations and real-time graphing i...
