Design Considerations for Visualization Transitions of 3D Spatial Data in Hybrid AR‐Desktop Environments

open access: yesComputer Graphics Forum, EarlyView.
We present design considerations for animated transitions of the appearance of 3D spatial datasets in a hybrid Augmented Reality‐desktop context. Such hybrid interfaces combine both traditional and immersive displays to facilitate the exploration of 2D and 3D data representations in the environment in which they are best displayed.

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

open access: yesThe Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

open access: yesIbis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

The State of Astronomy Education in the U.S.

open access: yes, 1996
I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

open access: yesJournal of Phycology, EarlyView.
Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate new hypotheses for the interpretation of metagenomic data and enrich ...

open access: yes, 2015
In India, astronomy has been studied from the beginning of civilization. The word amateur means involvement in work for pleasure rather than as a profession. So, amateur astronomers, in many places, prefer to be called non-professional astronomers.
