Groundwater movement in the surficial aquifer of the lower Coastal Plain cypress swamp‐pine flatwoods landscape of the southeastern USA is poorly documented. This study was conducted to define the patterns of horizontal groundwater flow through a typical landscape with particular attention to water exchange between cypress swamps and the surrounding areas. One hundred and twenty shallow water table wells 1 m deep were installed in a 42‐ha study area, one‐third of which was covered by pond cypress (Taxodium ascendens Brongn.) swamps. Water tables were measured approximately every 2 wk for 2 yr and the data were used to map water table elevation. Directions of horizontal groundwater flow were inferred from the water table topographic maps. Measured hydraulic heads were combined with saturated hydraulic conductivities to estimate groundwater flux. Most of the groundwater flowed through the swamps in response to the generalized surface elevation pattern. For selected ponds, the ground‐water also flowed from the swamps to the surrounding areas. It was uncommon for groundwater to flow into the ponds from the entire surrounding area. The pattern of groundwater exchange between the swamps and the surrounding area was related to the average water table depth: the deeper the average water table, the greater chance for groundwater to flow from the swamp into the surrounding area. Waterflow rates were estimated to be <56 cm d−1. These groundwater flow patterns are different from the generally accepted pattern of water flow and should be useful in defining the hydrologic cycle of these landscapes.
This controlled study investigates possible psychosocial deficits associated with the “double handicap” of mental handicap plus epilepsy in a sizeable sample of adults with mental handicaps living in the community. Results indicate that social and behavioural problems, additional to those associated with mental handicap in itself, are largely confined to the relatively small sub‐group of people who have poorly controlled epilepsy. These results are discussed in relation to deficiencies in the socialisation process.
ABSTRACT. The relationship beteween psychosocial behaviour, antiepileptic regime (polytherapy compared to monotherapy) and seizure frequency was explored in a sample of mentally handicapped adults living in the community. Locus of control perceptions were studied in relation to seizure frequency. Antiepileptic polypharmacy was found to have a detrimental effect upon psychosocial functioning independent of seizure frequency, which is itself a risk factor for social disturbance; and external perceptions of locus of control predominated. The distribution of drugs used is reported. These results are discussed in the context of implications for future research in the areas of coping, mental handicap and antiepileptic pharmacotherapy.
This paper presents a single case study of an epileptic hostel resident who presented behavioural problems in the form of high frequency pseudoepileptic seizures in association with an attention-seeking personality. Psychological intervention along behavioural lines was found to be lastingly effective in reducing the frequency of these seizures and generalized improvements were obtained in other areas of social skill. The results are discussed with reference to suggested implications for clinical practice.
ABSTRACT. The development of a new behaviour assessment scale is described. The scale focuses particularly upon disturbed behaviours which may be indicative of an ‘hysterical response tendency’. Factor analysis of the scale yielded a relatively ‘pure’ structure and the sub‐scales generated thereby provide a useful descriptive profile and help to define areas for a more detailed appraisal. Applications of the scale are discussed.
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.
