Lactation in Australian women : the effect of oral contraceptives on the vitamin and trace element content of breast milk

The aim of this project was to investigate the effects of oral contraceptives on the nutrient composition of breast milk. The design of the study also allowed the effects of stage of lactation and maternal diet on milk composition to be observed. A prospective study was designed to measure maternal dietary intake and vitamin and trace element concentration in milk and plasma. Vitamin A, ascorbic acid and iron, copper, zinc, manganese, selenium, cobalt, chromium, rubidium and caesium were measured. Two groups of women participated, oral contraceptive users and controls. Fasting milk and blood samples and 24-hour food records were collected from the women once a week for 20 weeks commencing 3-8 weeks post-partum, and 1-2 weeks before they began to take oral contraceptives. Fifteen women participated in the study; 5 took progestogen-only oral contraceptives, 1 took an oestrogen-progestogen oral contraceptive and 9 acted as controls. Progestogen-only oral contraceptives did not affect the milk or plasma concentration of the vitamins and trace elements measured. As only 1 subject took an oestrogen-progestogen preparation no conclusion could be drawn as to its effect. The mean milk and plasma concentration of all nutrients studied did not change significantly with the progression of lactation, with the exception of iron and zinc. The mean milk iron concentration was significantly higher at 16 weeks post-partum than at 8 and 23 weeks post-partum. The mean milk zinc concentration was significantly lower at 23 weeks post-partum than at 8 and 16 weeks post-partum. The infants1 mean estimated daily intakes of ascorbic acid and vitamin A from breast milk were above the U.S. and British Recommended Dietary Allowance for those vitamins. However, their mean estimated intakes of iron, zinc, copper, manganese and selenium were well below the U.S. recommendations. Effects of the maternal dietary intake on milk and plasma composition were variable. Implications of these findings have been discussed.

Repeated-viewing and co-viewing of an animated video : an examination of factors that impact on young children's comprehension of video content

The experiment reported here was concerned with the effect of repeat- viewing and adult co-viewing on the comprehension of an animated feature length movie. Four- to six-year-old children watched a movie on video either once or five times, and either with their mother present or on their own. The findings revealed that, after controlling for language skills and interest in the type of video watched, children who watched five times had higher comprehension scores than children who watched only once. Furthermore, children who watched the video repeatedly were also better at character identification and at identifying the good and bad qualities of one of the main characters in the movie. The presence of a mother, who was explicitly asked to co- view the movie with her child, did not facilitate comprehension. The findings are discussed in terms of the educational benefits of repeat viewing. Theoretical implications are also noted.

The interpretation of nature as spiritual content in painting

Investigates the interpretation of spiritual content in painting. Pt. 1 defines aspects of spirituality and explores the authors concerns of despiritualization. Pt. 2 parallels concerns with the Romantic movement & explores the notion of the sublime in relation to spiritual interpretation. Pt. 3 links the documented research to the body of studio work. The printings and drawings explore the authors concerns through the visual expression of concepts which suggest nature as a spiritual source.

Evaluation of individual program plan content and quality in a Victorian residential service

The study assesses the quality and content of Individual Program Plans for 284 Victorian adults with profound intellectual disabilities living in one residential service. A checklist was developed for improving plan quality, and measurement difficulties with checklists discussed. Recommends that a quality improvement process be implemented.
