Fusing BDS and Dihedral Corner Reflectors for High-Precision 3D Deformation Measurement: A Case Study in the Jinsha River Reservoir Area

open access: yesRemote Sensing
In mountainous canyon regions, BeiDou Navigation Satellite System (BDS)/Global Navigation Satellite System (GNSS) receivers are susceptible to multireflection and tropospheric factors, which frequently reduce the accuracy in monitoring vertical ...

Classical Horizontal Inequities in the Provision of Agricultural Income Support [PDF]

open access: yes, 2005
This paper explores the redistributive effect of classical horizontal inequities induced by agricultural support policy. Within farm type horizontal inequity (HI) is associated with differences in the level of support received by farms of a given type ...

Data from: How a GNSS receiver is held may affect static horizontal position accuracy

open access: yes, 2015
The static horizontal position accuracy of a mapping-grade GNSS receiver was tested in two forest types over two seasons, and subsequently was tested in one forest type against open sky conditions in the winter season. The main objective was to determine

UPSTREAM HORIZONTAL MERGERS, BARGAINING, VERTICAL CONTRACTS [PDF]

open access: yes
Contrary to the seminal paper of Horn and Wolinsky (1988), we demonstrate that upstream firms, which sell their products to competing downstream firms, do not always have incentives to merge horizontally. In particular, we show that when bargaining takes

Diagnosing Eyewitness Accuracy [PDF]

open access: yes, 2015
Eyewitnesses frequently mistake innocent people for the perpetrator of an observed crime. Such misidentifications have led to the wrongful convictions of many people. Despite this, no reliable method yet exists to determine eyewitness accuracy.

The Applicability of Ocean Physics Models to GNSS‐Acoustic Seafloor Geodesy

open access: yesEarth and Space Science
Global Navigation Satellite System‐Acoustic (GNSS‐A) seafloor geodetic observation is an effective technique not only for measuring offshore crustal deformation but also for detecting underwater sound speed structures.

Horizontal Equity: New Measures, Unclear Principles [PDF]

open access: yes
Alan Auerbach and Kevin Hassett offer a new measure of horizontal equity (HE) that is designed to overcome deficiencies in prior indexes. There is, however, a fundamental problem that their effort shares with their predecessors' attempts: the underlying ...

Decomposing Poverty Changes into Vertical and Horizontal Components [PDF]

open access: yes
Variations in aggregate poverty indices can be due to differences in average poverty intensity, to changes in the welfare distances between those poor of initially unequal welfare status, and/or to emerging disparities in welfare among those poor of ...

Comparing the accuracy and precision of smartphone and specialist handheld GNSS receivers for use in ecological fieldwork

open access: yesEcological Solutions and Evidence
Smartphones are handheld computers and multichannel communication devices that carry an array of sensors and can link with specialist external devices. These powerful tools have an established role in biological recording and ecological surveying.
