Touch, Sexuality and Power in Residential Settings

Summary This paper examines areas of concern surrounding touch, sexualityand associated power in residential establishments. The placeof touch and the expression of sexuality are considered in relationto residents and staff. It is suggested that these are importantfactors in framing a concept of residential care based on rightsand duties, and that current practice often takes a limitedperspective of some of the fundamental needs of residents     

Critical decision areas in corporate financial policy

The argument in this paper rests on the assumption that the prime objective of any corporate activity must in some way be related to a profitability goal, however this may be measured, however this may be defined, and however this may be constrained by the relevance of a times-cale.

The paper makes some comments on the selection of a corporate objective or goal but mainly it considers the direct contribution that financial management can make to achievement of this goal. It distinguishes this from the accounting rôle which is more appropriately concerned with measuring and monitoring progress towards the goal.     

THE EFFECT OF RETAIL PROMOTIONAL ACTIVITIES ON SALES*

This article reports the formulation and results of a multiple equation econometric model to relate retail sales by brand and package size to retail promotional variables for a branded, frequently purchased grocery product. Primary emphasis is placed on the formulation of the model as opposed to the results obtained from its use.     

Cancer risk estimation for mixtures of coal tars and benzo(a)pyrene.

Two-year chronic bioassays were conducted by using B6C3F1 female mice fed several concentrations of two different mixtures of coal tars from manufactured gas waste sites or benzo(a)pyrene (BaP). The purpose of the study was to obtain estimates of cancer potency of coal tar mixtures, by using conventional regulatory methods, for use in manufactured gas waste site remediation. A secondary purpose was to investigate the validity of using the concentration of a single potent carcinogen, in this case benzo(a)pyrene, to estimate the relative risk for a coal tar mixture. The study has shown that BaP dominates the cancer risk when its concentration is greater than 6,300 ppm in the coal tar mixture. In this case the most sensitive tissue site is the forestomach. Using low-dose linear extrapolation, the lifetime cancer risk for humans is estimated to be: Risk < 1.03 x 10(-4) (ppm coal tar in total diet) + 240 x 10(-4) (ppm BaP in total diet), based on forestomach tumors. If the BaP concentration in the coal tar mixture is less than 6,300 ppm, the more likely case, then lung tumors provide the largest estimated upper limit of risk, Risk < 2.55 x 10(-4) (ppm coal tar in total diet), with no contribution of BaP to lung tumors. The upper limit of the cancer potency (slope factor) for lifetime oral exposure to benzo(a)pyrene is 1.2 x 10(-3) per microgram per kg body weight per day from this Good Laboratory Practice (GLP) study compared with the current value of 7.3 x 10(-3) per microgram per kg body weight per day listed in the U.S. EPA Integrated Risk Information System.     

Learning about radon's risk

This article reports the results of an evaluation of the effectiveness of different types of information materials in communicating the risk from exposure to radon, a naturally occurring indoor air pollutant. The study involved a panel of 2300 homeowners who actually experienced risks from radon, and the information program used to explain these risks. The analysis considered information transfer and performance on specific tasks requiring information on the risk from radon to measure learning. The results suggest a systematic learning process, but indicate that the process can be influenced by how risk information is presented.     

Over-chastisement, Child Non-compliance and Parenting Skills: A Behavioural Interventiaon by a Family Centre Social Worker

Summary This single-case study describes a behavioural interventionby a Family Centre social worker with a family whose two eldestchildren had been registered on the Child Protection Registerfollowing an incident of over-chastisement by their mother.Working in partnership with the parents. a behavioural assessmentand intervention was undertaken over a four month periood. Theassessment suggested that child non-compliance was a centralproblem behaviour and that mother and child were caught in atrap where each negatively reinforced the other's aversive,coercive behaviour, since these behaviours were successful interminating the other's unwanted or aversive behaviours. Theintervention aimed to increase child compliance and reduce childdefiance using a positive reinforcement programme, and to increasethe mother's child management skills using a parent trainingprogramme. The results showed that child compliance with maternalinstructions increased significantly and that this was maintainedat eleven month follow-up. Also, mother's use of command negativedecreased significantly; this improvement was also maintainedat eleven month follow-up.
