ABSTRACT This paper introduces transboundary spanning as a novel concept for social movement analysis. Using Extinction Rebellion (XR) in the United States as a case study, we examine the relational dynamics of social movement boundary spanning: processes wherein actors and organizations engage across symbolic boundaries.

ROCK GLACIERS IN THE KOLYMA HIGHLAND
Based on remote mapping and field studies inGrand Rapids, Tumansky,Hasynsky,Del-Urechen Ridges as well as Dukchinsky and Kilgansky Mountain Massifs there were identified about 1160 landforms which morphologically are similar to the rock glaciers or they ...

Correlation Of Schmidt Hammer Rebound Numbers And Knocking Ball Stiffness Parameters For Sedimentary And Metasedimentary Rocks [PDF]
One of the most important rock properties is intact rock strength. The strength of an intact rock block material is determined by intact rock strength, which influences a fraction of the strength of a rock mass.

Schmidt Hammer exposure dating (SHED): Establishment and implications for the retreat of the last British Ice Sheet [PDF]
Ninety-eight surfaces related to the retreat of the British Ice Sheet (BIS) and dated using Terrestrial Cosmogenic Nuclide Dating (TCND) were sampled using the Schmidt Hammer to expand on relative dating techniques and establish Schmidt Hammer exposure ...

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries
ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.
