Manual for the Preparation and Staining of Embedded Natural Dry Bone Tissue Sections for Microscopy

In the last decade, the use of light microscopy has been firmly established for the investigation of exhumated human bone tissue. As a rule, these remains cannot be decalcified; thus, they are most commonly prepared for microscopic analysis as ground thin sections. These ground sections are of great value in diagnosing disease, in estimating age or in assessing taphonomic alteration. As bone is sometimes fragile and can be damaged by the grinding process, the specimen is occasionally supported by an embedding medium. In contrast to the vast amount of research conducted on embedded and unembedded unstained bone material, the use of histological stains on undecalcified dry bone tissue has been long neglected. In this article, a new method for embedding, sawing and grinding dry bone tissue is presented. The produced sections are subsequently stained with haematoxylin. The results show that even ground sections of fragile bone can be made in a quick and easy manner. Staining these sections enhances the envisioning of micro‐architecture and taphonomical processes. In addition, the sections stay open for inspection under polarized light. The results were consistent throughout the used bone material. To keep the method as accessible and comprehensive as possible, a step‐wise manual is provided. An additional troubleshooting paragraph discusses the most often encountered problems and provides solutions. Copyright © 2011 John Wiley & Sons, Ltd.     

Staining ground sections of natural dry bone tissue for microscopy

The histological staining of bone tissue is of great value in identifying structural changes in human bone tissue when examined microscopically, and is therefore routinely used by clinical pathologists. However, for archaeological and other types of undecalcified dry bone tissue, histochemical staining is currently not widely used. The purpose of this paper is to describe a new method developed for the staining of undecalcified archaeological bone which may be a valuable addition to the palaeopathological toolkit. Sections were ground by hand and stained with haematoxylin and eosin. The microstructure and architecture of the stained sections become clearly visible without compromising total tissue envisioning. In addition, staining enhances differentiation between taphonomically affected and non‐affected bone tissue. This paper accordingly describes a reproducible stepwise method for the production of ground stained sections. An additional troubleshooting paragraph discusses the most often encountered problems and provides solutions. Copyright © 2010 John Wiley & Sons, Ltd.     

THE WELFARE STATE AND THE MEDIA SYSTEM

This article aims to bridge the gap between media studies and welfare state studies. While media and communications systems are crucial elements in any society, these systems are often not included in studies of the welfare state. Through a discussion of five historical phases in the evolution of Scandinavian societies and media systems, from early democratization in the late 18th century through the ‘golden age’ of the welfare state to the present challenges of globalization, digitization and the fragmentation of social trust, the article discusses the relationships between the two spheres. While Scandinavian communications systems have much in common with those of other Western states, this article argues that they are also products of, and catalysts for, the specific evolution of the Nordic welfare states.
