Telework (paid work performed at home using new communications technologies) is a research site where concerns about globalisation, flexible work, technology and gender relations coalesce. My research suggests that the permeability of the boundary between home and work leads to power struggles around the use of domestic space and is symbolic of the wider negotiation of the conflicted identities of worker, parent and partner.  相似文献

Nodular limestones have been studied from the Lower Chasmops Shale (Middle Ordovician) and the Rytteráker Formation (Lower Silurian). Observations on nodule-host-rock relations and variations of ferroan/non-ferroan calcite cements help explain the role of precipitation, dissolution and redistribution of carbonate. Distribution and frequency of nodules depends on environmental parameters such as carbonate/clay ratio, grain size distribution and bioturbation, though final shapes are the result of pressure-dissolution and cleavage.  相似文献
