The neglect of a consideration of history has been a feature of mobility research. ‘History’ affects the results of analyses of social mobility by altering the occupational/industrial structure and by encouraging exchange mobility. Changes in industrial structure are rooted more directly in historical causes and can be seen as more fundamental than changes in occupational structure. Following a substantial review of the secondary literature on changes in industrial and occupational structure in Northern Ireland, loglinear analyses of intra- and intergenerational mobility tables for sociologically-derived cohort generations that incorporate occupational and industrial categories are presented. Structural and inheritance effects for industry are as significant as those for occupation. Given the well-established finding of ‘constant social fludity’ in mobility tables once structural effects are controlled, the inclusion of categorization by industry is necessary in order to reach an accurate understanding of occupational mobility and the role of historical change in mobility.

Flanders (1974) considered the Second World War to be the great social triumph and vindication of voluntarism in British industrial relations. This paper considers the experience of one region, Northern Ireland, functioning in a unique social and political context and considers the experience of its wartime industrial relations system. The political framework, trade union growth and representation, collective bargaining, strike activity including the major munitions strike of 1944 which may have provoked Defence Regulations Order 1AA, labour management and Joint Production Committees are all examined. The paper gives qualified support to Flanders’ conclusion.

Permeable reactive barriers are a technology that is one decade old, with most full-scale applications based on abiotic mechanisms. Though there is extensive literature on engineered bioreactors, natural biodegradation potential, and in situ remediation, it is only recently that engineered passive bioreactive barrier technology is being considered at the commercial scale to manage contaminated soil and groundwater risks. Recent full-scale studies are providing the scientific confidence in our understanding of coupled microbial (and genetic), hydrogeologic, and geochemical processes in this approach and have highlighted the need to further integrate engineering and science tools.

The survival of family farming in British agriculture has long been a topic of interest for rural researchers and is undergoing something of a current renewal of interest. However, insights from feminist approaches remain underutilised despite the crucial role farming women continue to play in family farming. This paper addresses the unity of farm, family and business by interpreting it as a patriarchal â??way of lifeâ??. An ethnographic-informed repeated life history methodology is employed to study in detail the family members of seven farms in rural mid-Wales. Findings show that the recent survival of the family farms investigated has been heavily dependent upon compliance with a patriarchal ideology that demands women be â??as good as goldâ??. However, it is discovered that a new view of women is emerging in the world of British family farming, that of â??gold diggerâ??. Women entering relationships with farming men are increasingly being considered a threat to farm survival by virtue of their entitlements if the relationship breaks down. The necessity to study the intricacies of personal relationships in family farming has important implications for most future research into this form of agricultural business arrangement.

Volatile organic compound (VOC) contamination of subsurface geological material and groundwater was discovered on the Nortel Monkstown industrial site, Belfast, Northern Ireland. The objectives of this study were to (1) investigate the characteristics of the geological material and its influences on contaminated groundwater flow across the site using borehole logs and hydrological evaluations, and (2) identify the contaminants and examine their distribution in the subsurface geological material and groundwater using chemical analysis. This report focuses on the eastern car park (ECP) which was a former storage area associated with trichloroethene (TCE) degreasing operations. This is where the greatest amount of volatile organic compounds (VOCs), particularly TCE, were detected. The study site is on a complex deposit of clayey glacial till with discontinuous coarser grained lenses, mainly silts, sands and gravel, which occur at 0.45–7.82 m below ground level (bgl). The lenses overall form an elongated formation that acts as a small unconfined shallow aquifer. There is a continuous low permeable stiff clayey till layer beneath the lenses that performs as an aquitard to the groundwater. Highest concentrations of VOCs, mainly TCE, in the geological material and groundwater are in these coarser lenses at ~4.5–7 m bgl. Highest TCE measurements at 390,000 µg L-1 for groundwater and at 39,000 µg kg-1 at 5.7 m for geological material were in borehole GA19 in the coarse lens zone. It is assumed that TCE gained entrance to the subsurface near this borehole where the clayey till was thin to absent above coarse lenses which provided little retardation to the vertical migration of this dense non-aqueous phase liquid (DNAPL) into the groundwater. However, TCE is present in low concentrations in the geological material overlying the coarse lens zone. Additionally, VOCs appear to be associated with poorly drained layers and in peat
