Sociological Forum, EarlyView.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.

Correlation Of Schmidt Hammer Rebound Numbers And Knocking Ball Stiffness Parameters For Sedimentary And Metasedimentary Rocks [PDF]
, 2022 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.

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries
Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.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.
