Strontium potently inhibits mineralisation in bone-forming primary rat osteoblast cultures and reduces numbers of osteoclasts in mouse marrow cultures

The basic mechanisms by which strontium ranelate acts on bone are still unclear. We show that an important action of strontium salts is to block calcification in cultures of osteoblasts, the bone-forming cells. These results suggest that strontium treatment could have previously overlooked effects on bone

Flow lines on Antarctic ice shelves

Satellite images of Ronne and Filchner ice shelves show a variety of surface features many of which are believed to indicate flow lines in the ice. Sufficient imagery is now available from Landsat satellites to plot these features from mosaics. Although some of the features have been recognized from aircraft, it was not until an overall view was provided that the true extent of the features and their relationship to the major ice streams became apparent. Using this evidence together with published ice thickness data from radio echo and seismic sounding, flow patterns within the ice shelves and tributary glaciers can be inferred

The language and organization of bullying at work

This article aims to uncover the ways that our understanding of bullying at work has become institutionalized. We argue that this institutionalization has limited our understanding of the ways that bullying is defined, constructed, experienced, resisted, and accounted for in organizations. The research draws on Phillips, Lawrence, and Hardy's Discursive Model of Institutionalization (DMI) when considering various texts about bullying at work and their role in institutionalizing bullying. As a result of doing this, we draw attention away from the dominant perspectives conceptualizing workplace bullying as an individual or interpersonal issue to explore the wider disputes over definitions and the discursive negotiation of what is and is not bullying at work within organizations. We investigate how, through the discursive effects of action, texts of bullying are created, legitimized, embedded in discourse, and institutionalized. However, we highlight that resistance challenges the rights to speak, undermines the rationality of claims, and challenges moral evaluation. We demonstrate that DMI is a useful concept for exploring the processes involved in institutionalizing. We show that bullying at work is a highly complex area where polyphony is important, and we highlight how, through the anchoring in a dominant, individualizing discourse (that usually is taken for granted), workers are produced and reproduced to fit the dominant discourse. We argue that analyzing the texts and discourses of bullying deployed by a broad range of participants at work allows us to observe the processes by which concepts may become institutionalized as well the processes by which they may resist institutionalization
