摘要

The present invention relates to a method for manufacturing a security paper, for security or value documents, that exhibits at least one through opening (12) having characteristic irregularities (14) in the edge region. According to the present invention, a paper web having thin sites in the form of the outline of the desired shape of the at least one through opening (12) is formed on a paper mold, and the paper web dewatered after sheet formation, the region delimited by the thin sites being removed from the paper web by the occurring forces.

7. Women as Change Agents in the World’s Rangelands: Synthesis and Way ForwardiiWe synthesize findings reported from papers based on invited presentations given at a symposium entitled Women as Change Agents in the World’s Rangelands, held Tuesday 5 February 2013, at the 66th Annual Meeting of the Society for Range Management (SRM) in Oklahoma City, Oklahoma. The International Affairs Committee of SRM organized this symposium. General information about the symposium is posted at: http://www.rangelands.org/internationalaffairs/iac_symposia.shtml. This paper occurs at the end of a special issue of Rangelands that contains the aforementioned papers. Hence, this paper serves as a summary rather than an introduction. Those interested in details on methods or research perspectives should read the contributed papers. [O] . D. Layne Coppock, María E. Fernández-Giménez, Jeannie Harvey 2013
