Comparison of the levels of students' career maturity resulting from two models for the delivery of career education programs in selected Victorian government secondary schools

At both national and state levels, the delivery of career education has been recommended to follow an integrated model with a high level of staff participation across the school. However it has been found that in many schools the career education program is primarily delivered by a careers teacher. This study compared whether the recommended integrated model or the specialist careers teacher model delivered better outcomes for students in terms of their levels of career maturity. The main finding of the research is that the integrated model of delivery of career education programs did make a significant difference to the cognitive career maturity of the students in the selected Victorian governement secondary schools.

Impact of four foreign aided projects on developments in secondary education in Bangladesh

Examines four foreign aided development projects in the secondary education sub-sector in Bangladesh. Investigates planning and implementation practices employed during the life of the four projects in order to identify factors likely to lead to greater sustainability of development projects financed with foreign aid. A major concern was how foreign aided projects sustain, or lack the means to sustain, developments that have begun when project funding ceases.

The second phase uses eleven case study interviews to discover the teachers' conceptions of communicative language teaching. Identifies elements of team taught lessons and elucidates the conceptions of communicative language teaching held by a sample of teachers.

Role of primary / secondary control in positive psychological adjustment

Challenges previous theory regarding the relationship between control and positive psychological health by finding a much greater role for control over peoples' internal emotions in positive psychological adjustment than was previously theorised. Presents a new tool for the measurement of control that realises the adaptive value of control over both the person's external environment and their internal psychological processes.

Using CAI to teach chemistry in secondary schools in Thailand

Participatory action research is used by six Thai chemistry teachers being supported to become more 'computer literate' and to develop understandings about the effectiveness of ways of using a chemistry CAI package to support student learning. The study demonstrates a gradual change in their ideas and attitudes to the use of computers in teaching.

Benign recurrent intrahepatic cholestasis with secondary renal impairment treated with extracorporeal albumin dialysis

Benign recurrent intrahepatic cholestasis (BRIC) is a rare autosomal recessive condition characterized by intermittent episodes of pruritis and jaundice that may last days to months. Treatment is often ineffective and symptoms, particularly pruritis, can be severe. Extracorporeal albumin dialysis (molecular adsorbent recycling system, MARS) is a novel treatment which removes albumin bound toxins including bilirubin and bile salts. We describe a case of a 34-year-old man with BRIC and secondary renal impairment who, having failed standard medical therapy, was treated with MARS. The treatment immediately improved his symptoms, renal and liver function tests and appeared to terminate the episode of cholestasis. We conclude that MARS is a safe and effective treatment for BRIC with associated renal impairment.

Obstructive jaundice secondary to neuroendocrine tumour in a patient with von Recklinghausen's disease

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder, with variable clinical manifestations and unpredictable course, associated with an increased incidence of various tumours. Plexiform neurofibromas are hallmark lesions of NF1; they are slow-growing tumours, which account for substantial morbidity, including disfigurement and functional impairment, and may even be life-threatening. Neuroendocrine tumours (NETs), a rare diverse group of neoplasms, are occasionally associated with neurofibromatosis. Pancreatic NETs are tumours with an incidence of less than 1/100 000 population/year and complex patterns of behaviour, which often need complicated strategies for optimal management. We present the case of a young adult with NF1, having a unique concurrence of plexiform neurofibroma involving the liver with an ampullary NET, and we discuss step by step the management in a specialist centre.

Investigation of the postcure reaction and surface energy of epoxy resins using time-of-flight secondary ion mass spectrometry and contact-angle measurements

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to investigate correlations between the molecular changes and postcuring reaction on the surface of a diglycidyl ether of bisphenol A and diglycidylether of bisphenol F based epoxy resin cured with two different amine-based hardeners. The aim of this work was to present a proof of concept that ToF-SIMS has the ability to provide information regarding the reaction steps, path, and mechanism for organic reactions in general and for epoxy resin curing and postcuring reactions in particular. Contact-angle measurements were taken for the cured and postcured epoxy resins to correlate changes in the surface energy with the molecular structure of the surface. Principal components analysis (PCA) of the ToFSIMS positive spectra explained the variance in the molecular information, which was related to the resin curing and postcuring reactions with different hardeners and to the surface energy values. The first principal component captured information related to the chemical phenomena of the curing reaction path, branching, and network density based on changes in the relative ion density of the aliphatic hydrocarbon and the C₇H₇O⁺ positive ions. The second principal component captured information related to the difference in the surface energy, which was correlated to the difference in the relative intensity of the C_xH_yN_z⁺ ions of the samples. PCA of the negative spectra provided insight into the extent of consumption of the hardener molecules in the curing and postcuring reactions of both systems based on the relative ion intensity of the nitrogen-containing negative ions and showed molecular correlations with the sample surface energy.

Time-of-flight secondary ion mass spectrometry investigation of epoxy resin curing behavior in real time

Time-of-flight secondary ion mass spectrometry and principal components analysis were used in real time to monitor the progress of curing reactions on the surface of a diglycidyl ether of bisphenol A (DGEBA) and diglycidyl ether of bisphenol F (DGEBF) epoxy resin blend reacted with the diamine hardener isophorone diamine at different time intervals. Molecular ions in the mass spectra that characterized the curing reactions steps, including blocking, coupling, branching, and crosslinking, were identified. The aliphatic hydrocarbon ions were correlated to the curing reaction rate, and this indicated that coupling and branching occurred much faster than the blocking and crosslinking curing reactions steps. The total conversion of the coupling and branching reaction steps were followed on the basis of changes with time in the relative ion intensity of molecular ions assigned to the DGEBA/DGEBF, aliphatic hydrocarbon, epoxide, and aromatic ring structures. Indicative measures of crosslinking density were monitored through the observation of changes in the ratio of the relative intensities of the aliphatic hydrocarbon and hydroxyl molecular ions over time. The curing reaction conversion was established by the observation of the changes in the relative ion intensity of the molecular ions that were related to the DGEBA/ DGEBF molecules.

Computers for secondary mathematics: who uses them and how?

In the first stage of a three year ARC-funded study in which the effects of using computers for the teaching and learning of mathematics are being explored, a questionnaire has been developed and is being administered to a large number of students in grades 7-10 in a representative sample of co-educational post-primary schools in Victoria. Using open and closed response formats, the information sought includes: background and biographical details; data on computer ownership and use =96 frequency and mode/s =96 for mathematics learning at home and in mathematics classes; and beliefs about mathematics and the use of computers for learning mathematics. In this paper, the focus will be on some of the preliminary findings related to ownership and use of computers for learning mathematics at home and at school. In previous research, factors such as gender, socio-economic background, and ethnicity have been identified as contributors to inequitable mathematics learning outcomes. The questionnaire data will be analysed to examine if these and other factors are related to any inequities identified in student's access to computers and in how they use computers in their learning of mathematics. The results will be presented and pertinent implications discussed.
