Department of the Environment revealed an extensive Iron Age settlement and traces of widespread Roman agricultural and industrial activity at Wakerley, Northamptonshire (FIG. 2). The settlement was situated in Wakerley parish, immediately to the south of the road running between the villages of Wakerley and Harringworth and nine miles north-northeast of Corby 3 (FIG. 3). It was sited on sloping ground, overlooking the valley of the River Welland, and some \ mile from the river itself. From the site there are extensive views of the river valley to the north and west and of the hills and dales of Rutland that lie beyond. A deep natural gully occurs in the hillside, just to the west of the settlement and, as a result, the site is in an open position and fully exposed to the westerly winds. The settlement was located between the 250 and 300 ft. contours on a wide expanse of Lower Lincolnshire Limestone. Clays of the Lower Estuarine Series and outcrops of Northampton Sand and Ironstone occur on the lower slopes of the valley below the site and in the adjacent gully to the west. It is likely that a convenient supply of water would have been available in this gully in earlier periods, but this has been piped away in modern times. Some 150 m to the southwest , on the opposite side of the gully, an Anglo-Saxon cemetery was excavated by D. A. Jackson during 1968 and 1970 (report forthcoming). A small number of burials of Saxon date were found within the area of the excavation described below. Further to the southwest , some 600 m from the Iron Age and Roman site, the stone foundations of a Roman aisled barn, measuring 30 by 14 m, have also been excavated. The barn overlay earlier buildings and it is hoped that further work on this site will be possible in the future. Extensive quarrying southwest of the settlement has revealed isolated Iron 1 T. M. Ambrose has described the small finds and shared in the general preparation of this report. 2 A. L. Pacitto directed the excavation of an unusual concentration of iron-smelting furnaces, and his report is incorporated in the section on iron-working. P. J. Woods (with the assistance of R. E. Turland) excavated the three Romano-British pottery kilns and has described the results in this report. With the help of R. E. Turland he also carried out all the post-excavation work on the Romano-British pottery and has described and discussed the pottery in relation to the site as a whole. Grateful thanks are due to Miss S. A. Butcher for her report on the brooches and to Alison Cook for her report on the Anglo-Saxon grave-goods. Mr L. Biek and Dr R. F. Tylecote contributed to the section on iron-working, and thanks are due to them for visiting the site and making valuable suggestions during the excavations. Other specialist contributions are gratefully acknowledged from F.
Longevity is without a doubt on the rise throughout the world due to advances in technology and health. Since 1960, Ghana’s average annual mortality improvement has been about 1.236%. This poses serious longevity risks to numerous longevity-bearing assets and liabilities. As a result, this research investigates the effect of mortality improvement on pension annuities related to a particular pension scheme in Ghana. Different stochastic mortality models (Lee–Carter, Renshaw–Haberman, Cairns–Blake–Dowd, and Quadratic Cairns–Blake–Dowd) are used to forecast mortality improvements between 2021 and 2030. The results from accuracy metrics indicate that the quadratic Cairns–Blake–Dowd model exhibits the best fit to the mortality data. The findings from the study demonstrate that mortality for increasing ages within the retirement period was declining, with increasing improvement associated with increasing ages. Furthermore, the forecasts were used to estimate the associated single benefit annuity for a GHS 1 per annum payment to pensioners, and it was discovered that the annuity value expected to be paid to such people was not significantly different regardless of the pensioner’s current age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
