Cadmium and human prostatic carcinoma : a study of the analytical procedures for the determination of cadmium and zinc in human prostatic tissue, and the investigation of an association between the incidence of prosatatic adencarcinoma and the occurrence of prostatic cadmium
Description:
The concentrations of the heavy metals cadmium and zinc in both benign nodular hyperplastic and malignant (adenocarcinoma) human prostatic tissue obtained from Trans Urethral Resections of the Prostate (TURP) have been investigated. Healthy normal human prostates obtained from post mortem cadavers were used as controls. The change in the prostatic cadmium concentration with age was investigated. Renal cortex cadmium and zinc concentration changes with age together with the metal concentration intterelationships between prostatic and renal cortex tissues were studied. "From abstract"

The thesis reported on experiments conducted aimed at controlling toad rush when pastures were being established. Experiments were undertaken using a range of herbicides. As a result of these tests the author asserts there is great potential for improving the establishment of new pastures.
Description:
The timing of breeding and habitat preference in the stubble quail (Coturnix pectoralis) were assessed at two study sites, Dookie and Mitiamo, in the north of Victoria. Surveying was over and eight month period between September 1993 - April 1994. Reproductive timing was determined by monitoring changes in the gomad size of shot birds. Breeding events were verified by disproportionate increases in the number of young birds shot. Population density was measured as an indicator of habitat preference. Site characteristics known to affect habitat selection were monitored. Breeding was in spring and autumn. Spring breeding coincided with the period of maximum plant growth. Autumn breeding was stimulated by above average late summer rainfall. Male stubble quail were shot in greater numbers during a known breeding event. Stubble quail preferred areas of lightly grazed pasture dominanted by native grass species. Recently harvested wheat and barley stubble provided an abundant short-term food supply, however the ability of this habitat type to support resident stubble quail populations is questioned. Stubble quail population density appeared to be strongly influenced by territorial behaviour during breeding. Implications for the management of this game species are discussed and future lines of research recommended.

Description:
The purpose of the study was to examine the effect of a group training program, based on cognitive behavioural theory and techniques, on the problem-solving skills of adolescents. Evidence of a link between suicidal ideation (engaging in suicidal thinking) and reported deficits in social problem-solving or coping competence levels in adolescents is an area of investigation that offers some hope for suicide primary prevention programs. The study tried to determine if teaching social problem solving skills in a school would better equip adolescents with coping with problematic situations. The work of Hawton (1997) Hawton and Kirk (1989), Lerner and Clum (1990) and McLeavey, Daly, Ludgate and Murray (1994) formed the basis of the training program design. The emphasis was on general problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing problem-solving skills rather on a participant’s specific current problems. Included was training in listening skills, assistance in developing appropriate problem-solving behaviours and role simulation through the use of structured video case scenarios. Seventy four male and female year 10 secondary school students were subjects in the study. They were randomly divided into two, approximately equal, groups. Thirty six subjects established the control group and the remaining thirty eight constituted the experimental group. The findings indicated that students exposed to the problem solving training program did not have significantly higher problem-solving ability, as measured by the Problem Solving Inventory (PSI) than those who were not exposed to the training. However, females in the experimental group were significantly more likely to make conscious decisions about when they would approach or avoid a problem when compared to control group females. It is suggested that the adaptation of training, designed for suicidal clients, needs to be explored further for application to Year 10 students in the general population. More research is needed into ways to provide school based preventative training programs that will assist in the development of coping skills.

"There is a dearth of information about the current use and management of hazardous substances in workplaces. This project aimed to contribute knowledge in this area by drawing on the practical experience of worker-elected health and safety representatives. This was undertaken by surveying a random sample of 7178 representatives registered with former South Australian Occupational and Safety Commission's Health and Safety Representatives Database. The survey results indicated widespread use of hazard substances although there were differences between industries and work force sectors in the range of chemical types used, the nature and degree of contact that workers have with them. Use of some chemical types was also widespread in a number of industries. Container labelling and access to material safety data sheets were found to be established in many workplaces and some form of assessment to decide how to protect workers was also often undertaken. Baseline information was obtained against which the impact of proposed regulatory reforms to control workplace hazardous substances (consistent with Workplace Australia's National Model Regulations for the Contol of Workplace Hazardous Substances) can be evaluated. This information can also be used in the planning and targeting of educative and other preventive strategies to minimise risks to health and safety arising from work with hazardous substances."

Description:
The principal aim of this study is to survey parents' perceptions of the influence of imported children's television programs on their children's behaviour. The survey was carried out in the Jakarta area. The study was promoted by a desire to investigate the claim made by some social commentators in Indonesia recently that children's behaviour was worsening, especially since the rapid expansion of commercial television. For the survey, a group of 388 parents of mixed socio-economic status were questioned. As a further step, qualitative research techniques were used to interview key personnel from the Indonesian television industry. Both the quantitative and qualitative data obtained was related to imported children's programs broadcast on both commercial and government channels. The result indicate that there w as no significant correlation between increased negative behaviour in children and the watching of imported children's programs. Most parents were inclined toward the view that they could not be certain whether or not their children's behaviour was influenced by imported children's television programs. Neither did they consider such programs to have a negative influence on their children's behaviour. Variation in parents' socio-economic status did not lead to a significant difference in percentages. Since parents did not perceive there to be any correlation, there may be other factors at work leading children to behave in increasingly negative ways, or perhaps the social commentators are mistaken and children's behaviour is not worsening at all
