Exchange reactions of group IV phosphines

This thesis describes a variety of exchange reactions of phosphorus derivatives of the type Q₃P where Q can be silyl, germyl trimethylsilyl, tributyltin and trimethyltin. These phosphines are treated with silyl and germyl halides and the products of reaction are investigated by n.m.r. spectroscopy.Farther exchange reactions were carried out on the phosphines (type Q₃P) with PF₂Br. A new diphosphine (GeH₃)₂PPF₂ was isolated and many other diphosphines were prepared in solution, though for a variety of reasons no other derivatives were found to be isolable. It was possible to obtain the n.m.r. parameters of a widé variety of compounds.The formation of bis(PF₂) and tris (PF₂) was observed in the n.m.r. spectrum of a reaction involving the tin phosphine (Bu₃ⁿSn)₃P and an excess of PF₂Br. The doubly and triple substituted phosphines i.e. (PF₂)₂PSnBu₃ⁿ and (PF₂)₃P could be identified in the various spectra that were recorded.Borane adducts were prepared of several of the new diphosphines and were likewise characterised by n.m.r. analysis.As (GeH₃)₂PPF₂ was isolable, it was characterised by vibrational spectroscopy. The photoelectron spt:ctru.m was recorded and preliminary structural ideas could be made. The gas phase electron diffraction study enabled the bond lengths and angles to be measured.The diphosphine (GeH₃)₂PPF₂ was farther subjected to reaction with a variety of reagents to investigate cleavage of the P-P bond, co- ordination on to organometailic compounds and possible farther exchange.Conclusions and suggestions for farther work are made

Record Linkage Techniques: Exploring and developing data matching methods to create national record linkage infrastructure to support population level research

In a world where the growth in digital information and systems continues to expand, researchers have access to unprecedented amounts of data. These large and complex data reservoirs require creative, innovative and scalable tools to unlock the potential of this ‘big data’. Record linkage is a powerful tool in the ‘big data’ arsenal. This thesis demonstrates the value of national record linkage infrastructure and how this has been achieved for the Australian research community

The development of an exceptional Brethern ministers scale for the California Psychological Inventory

The purpose of this study was to develop an Exceptional Brethren Ministers Scale for the California Psychological Inventory. This scale was designed to differentiate between effective and ineffective parish pastors in the Church of the Brethren.;The procedure involved the identification of two groups of parish clergy in the Church of the Brethren. These groups were formulated using a Pastoral Effectivenes Rating Form, (PERF). A list containing 160 items was circulated among a group of experts in ministry in the Church of the Brethren for their appraisal. The experts rated each item according to its efficacy in discriminating between effective and ineffective parish pastors. Forty-two items were selected for PERF. The PERF was then tested in a pilot study and was submitted to district executives within the denomination. The district executives used the PERF to rate the pastors in their respective districts. The accumulated ratings were rank-ordered, and the 80 pastors who received the highest ratings and the 80 with the lowest ratings were selected as subject for the study. These 160 subjects were contacted and were asked to complete the California Psychological Inventory. Ninety-three agreed to participate and were divided into the two criterion groups for the development of the Exceptional Brethren Ministers Scale.;The hypothesis for the study was that a valid Exceptional Brethren Ministers Scale could be developed for the California Psychological Inventory that would discriminate between effective and ineffective Church of the Brethren Parish Clergy. Although validation samples were unavailable, a scale was produced using a 2 x 2 contingency chi-square analysis. The new scale consisted of 45 items which reached statistical significance. A oneway ANOVA was used to compare the two criterion groups on the 18 standard CPI scales. Significant differences were obtained on eight scales which included Capacity for Status, Sociability, Social Presence, Self-acceptance, Tolerance, Achievement via Conformance, Achievement via Independence, and Intellectual Efficiency. With each of these scales the scores received by the most effective criterion group exceeded those obtained by the least effective group

Environmental management and ISO 14000: ISO/Swiss government regional itinerant training seminar for developing and emerging countries

Conclusions: The authors were impressed with the organisation of these seminars and the warm hospitality they received. The positive attitude of everyone concerned was extremely motivating. Events such as these are vital in disseminating know-how of LCA into these countries. It was and will be a big opportunity to introduce LCA together with environmental management systems and eco-labelling under the umbrella of the ISO 14000 series. In this respect organisations have the chance to choose from a number of tools to meet a variety of needs and situations. Further seminars and more detailed information are necessary. It is in everyone's best interests that organisations in developing countries have access to the management tools which allow them to operate in an environmentally responsible manner. For future activities it is believed that the principle "train the trainers” would be the most beneficial approach. To conclude it must be stated that these events were a great experience for all involved, both participants and lecturer
