This paper presents results of the longitudinal usability and network trials that took place throughout the COVEN (COllaborative Virtual ENvironments) Project. To address the lack of understanding about usability design and evaluation for collaborative virtual environments (CVEs), a deductive analysis was used to systematically identify areas of inquiry. We present a summary of the analysis and the resulting framework through which various complementary methods were utilized during our studies. The objective of these studies was to gain a better understanding about design, usability, and utility for CVEs in a multidisciplinary setting. During the studies, which span four years, we undertook longitudinal studies of user behavior and computational demands during network trials, usability inspections of each iteration of the project demonstrators, consumer evaluations to assess social acceptability and utility of our demonstrators, and continuous preparations of design guidelines for future developers of CVEs. In this paper, we discuss the need for such activities, give an overview of our development of methods and adaptation of existing methods, give a number of explanatory examples, and review the future requirements in this area.

Integrated Methods

Specifically, the authors’ research focuses on employing automatic usability evaluations to identify problems. For example, they analyze the operation histories, but do not focus on manually performed evaluations such as heuristic ones. They assume their research can aid software developers and usability engineers because their work allows them to recognize the more serious problems. Consequently, the software can be modified to resolve the usability problems and better meet the end users’ requirements. In the future, the authors strive to integrate more diverse usability evaluations, including heuristic evaluations, to refine integration capabilities, to identify problems in more detail, and to improve the effectiveness of the usability evaluations.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Human And Mouse

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.
