Arctic Dreams: Imagination and Desire in a Northern Landscape

Abstract: A celebration of a strange elemental landscape - of the animals and people who live there; of its history and future; of the dreams it inspires. Above all it is about the relationship between human imagination and the landscape. The author also wrote "Of Wolves and Men".

Effects of Word and Morpheme Familiarity on Reading of Derived Words.

Abstract: The purpose of this study is to examine factors that influence students’ reading of derived words. Recent research suggests that the lexical quality of a derived word depends on the familiarity of the word, its morphemic constituents (i.e., base word and affixes), and the frequency with which the base word appears in other words (i.e., members of the same word family or family frequency). On the premise that better and more experienced readers have higher quality lexical representations, we explore the extent to which accuracy of reading derived words by 4th and 6th graders is related to measures of familiarity, including derived and base word frequencies, family size, average family frequency, and word length. The results of an exploratory factor analysis indicated that these measures formed two factors, one representing morphemic constitution and the second representing exposure to the word family; both factors accounted for significant variance in the students’ derived word reading. Comparisons of sets of derived words contrasted on familiarity properties showed that performance on derived words, overall, is better for 6th than 4th graders and for good than poor readers. On the measures of family frequency and family size, there were significant discrepancies between grade level and reading ability and frequency characteristics. These add support to the view that morphemic analysis and wide reading experience contribute to derived word reading.

Effective manipulation of the electronic effects and its influence on the emission of 5-substituted tris(8-quinolinolate) aluminum(III) complexes.

Abstract: The unique electron-transport and emissive properties of tris(8-quinolinolate) aluminum(III) (Alq(3)) have resulted in extensive use of this material for small molecular organic light-emitting diode (OLED) fabrication. So far, efforts to prepare stable and easy-to-process red/green/blue (RGB)-emitting Alq(3) derivatives have met with only a limited success. In this paper, we describe how the electronic nature of various substituents, projected via an arylethynyl or aryl spacer to the position of the highest HOMO density (C5), may be used for effective emission tuning to obtain blue-, green-, and red-emitting materials. The synthetic strategy consists of four different pathways for the attachment of electron-donating and electron-withdrawing aryl or arylethynyl substituents to the 5-position of the quinolinolate ring. Successful tuning of the emission color covering the whole visible spectrum (lambda=450-800 nm) was achieved. In addition, the photophysical properties of the luminophores were found to correlate with the Hammett constant of the respective substituents, providing a powerful strategy with which to predict the optical properties of new materials. We also demonstrate that the electronic nature of the substituent affects the emission properties of the resulting complex through effective modification of the HOMO levels of the quinolinolate ligand.
