Designing for biodiversity data in place: Species, encounters, and interfaces
People and Nature, EarlyView.Abstract Species occurrence data, which records the presence of an organism at a point in space and time, is central to environmental science and its opening up to new forms of participation such as citizen science. Such data are increasingly aggregated and mobilised, reaching diverse audiences.

THE KINEMATICS PARAMETERS OF THE GALAXY USING DATA OF MODERN ASTROMETRIC CATALOGUES
Odessa Astronomical Publications, 2016 Based on the Ogorodnikov-Milne model, we analyze the proper motions of XPM2, UCAC4 and PPMXL stars. To estimate distances to the stars we used the method of statistical parallaxes herewith the random errors of the distance estimations do not exceed 10 ...

Accounting for animal movement during aerial imaging surveys
Remote Sensing in Ecology and Conservation, EarlyView.Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

The Frequency Distribution of Some Measured Parallaxes and of the Parallaxes Themselves [PDF]
Proceedings of the National Academy of Sciences, 1925 It is well known that the frequency functions of a set of quantities and of their measures are different ; if the error of measurement is comparable in magnitude to the quantity determined, they nmay be decidedly dissimilar. In the case of good photographic parallaxes the reported probable errors average about eight one-thousandths of a second of arc ...

, 2007 Introduction The distance of the stars was probably the most eagerly awaited fruit of the Hipparcos mission and was indeed the key element that led eventually to the decision to design a dedicated space experiment.
Hipparcos Parallaxes
core
The Astrophysical JournalWe report trigonometric parallaxes and proper motions for three water masers and one methanol maser obtained with the Very Long Baseline Array as part of the Bar and Spiral Structure Legacy Survey.

Journal of the Royal Anthropological Institute, EarlyView.Based on ethnographic research at Rūm Orthodox Christian monasteries in Lebanon, the article studies scenes of Islam at the monastery as they intersect with anxious public debates on, and anthropological theorizations of, sectarianism and ‘Muslim–Christian’ relations in the Mashriq.

Trigonometric parallaxes of high velocity halo white dwarf candidates
, 2007 International audienceThe status of 38 halo white dwarf candidates identified by Oppenheimer et al. (2001) has been intensively discussed by various authors. In analyses undertaken to date, trigonometric parallaxes are crucial missing data.

Astronomy & AstrophysicsRecent work has established large samples of astrometrically confirmed RR Lyrae and type-II Cepheid members of Galactic globular clusters (GCs). Any given GC can contain multiple such stars at once, notably RR Lyrae stars pulsating in the fundamental ...

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range
International Journal of Urban and Regional Research, EarlyView.Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...
