Collaborative working with specific speech & language disorder in mainstream education.

Children with specific speech and language disorders are part of a special needs population whose educational and therapeutic needs have been provided for in a variety of settings over the last fifty years. Changes have been implemented in response to a range of legislation. This has also had implications for the delivery and type of provision of the children's education and therapy. The National Health Service and local education authorities (LEAs) have had to respond to legislation and continue to provide for the full range of specific speech and language disorders. This paper will outline how therapeutic input has had to adapt to the changing educational context. Changes in delivery have necessitated a redefinement of roles and adjustments in collaborative working.

Geographic distance and contact between middle-aged children and their parents: the effects of social class over 20 years.

This research derives and tests hypotheses from two alternative conceptual models: the modified extended family model, and the changing family constraints model, which takes into account recent changes in work and family life. The hypotheses address social class differences in geographic distance and contact frequency between middle-aged children and their parents over time. Simultaneous probit models are used to analyze distance and contact as jointly determined outcomes with data from the USC Longitudinal Study of Generations and Mental Health. Results from these analyses indicate that children's 1971 educational aspirations and social class positions predict 1991 distance and contact between generations. Parents who have lower 1991 incomes, however, live farther from children and talk with them on the telephone less frequently than higher-income parents. Thus, the effects of early social class position support the modified extended family model, whereas the effects of current social class position support the changing family constraints model.

Fish oil increases peripheral capillary blood cell velocity in humans.

Fish oils containing n-3 fatty acids have been shown in humans to decrease platelet aggregation in vitro, lower plasma triglycerides, and to increase bleeding time. The in vivo effects of fish oils on microcirculatory blood flow in humans has not been studied to date. Twenty-one male subjects were randomly assigned to either olive oil (n = 10) or fish oil (n = 11) supplemented groups to determine the effects of these oils on capillary blood flow velocity (CBV) in the nailfold area. The subjects were given the oils for three weeks (1.5 g oil/10 kg b.wt./day) in a single blind study design. In addition to CBV plasma lipid profiles, blood viscosity, blood pressure and platelet and erythrocyte fatty acids were also determined prior to and after the dietary intervention. Fish oil supplementation significantly increased CBV, by 1.75-fold (0.144 +/- 0.069 to 0.253 +/- 0.147 mm/s). The olive oil group remained unchanged. Increased levels of n-3 fatty acids were noted in platelets and erythrocytes of the fish compared to olive oil-supplemented groups. Blood viscosity was unaltered in both groups, however, blood pressure in the olive oil supplemented group was significantly decreased. Plasma triglycerides were significantly decreased in the fish oil supplemented group. These observations suggest that increases in CBV after fish oil supplementation are due to changes in vascular tone and not to alterations in blood pressure or blood viscosity.
