Categorization Scheme

In this paper, we present the methodology and results from the evaluation of shapeSIFT: a multi-dimensional visualization tool for exploring part repositories in the context of eco-conscious design. The goals of this work are twofold, to create a categorization scheme for user evaluation methods specific to information visualization tools in eco-conscious design, and to formulate a user study for the shapeSIFT interface based on the developed categorization scheme. Our proposed scheme categorizes user evaluation methods based on two axes, (a) focus of the conducted user evaluation, and (b) development stage of the tool being evaluated. This scheme was used as the basis for conducting a guided formative expert review of the shapeSIFT interface with five domain experts in an industry setting. In this study we gathered experts’ comments, feedback, and usage behaviors, while they used the shapeSIFT interface to perform tasks reflective of real-world design practices. Results from the study show that shapeSIFT was easy-to-use and effective for part selection in the context of redesign. Motivated by these positive preliminary results, we intend to improve the shapeSIFT interface and conduct follow-up studies with a larger pool of designers.

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.

Chromatin Structure And Dynamics

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.
