This thesis presents a study of the incidence of hypercholesterolaemia in a 1988 sample of male personnel from the Royal Australian Air Force (RAAF). The thesis defines hypercholesterolaemia as a plasma total cholesterol level in excess of the risk threshold promulgated by the National Heart Foundation of Australia (NHF). Since 1981, RAAF personnel have been subjected to a series of regular physical and physiological examinations, including a comprehensive blood lipd profile, as part of a preventive approach to reducing the incidence of coronary heart disease in the Service. The study presents data on the extent of hypercholesterolaemia in the RAAF and illustrates the spread of the condition through various age cohorts. In excess of 40% of the RAAF personnel studied had total cholesterol levels in excess of the NHF "increased risk" threshold with the prevalence varying from 11.8% of personnel aged 20-24 years to some 64% of personnel older than 49 years. The increase in total cholesterol level with increasing age is statistically significant. The study compares these data with previously published observations on certain motivational characteristics of military communities, with a view to providing an evaluation of the structure of the RAAF Health Promotion Programme as a lifestyle based educational initiative. The data are further compared with data from two conceptually similar studies of male personnel in the United States armed forces. These comparisons suggest that the age related frequency of educational intervention which characterized the 1988 RAAF programme may well have been inappropriate for optimal effect. The study further utilizes a tabular (matrix) analysis of a number of educational strategies to identify several preferred option(s) for programme design in the RAAF community. The analysis suggests that the present mode of educational intervention may also be inappropriate for optimal effect (when addressing the 1988 RAAF population at least). The study concludes with the presentation of a series of recommendations aimed fundamentally at a redesign of the cholesterol monitoring component of the RAAF Health Promotion Programme. The study recommends, however, that given the multifactorial nature of coronary heart disease risk, the cholesterol monitoring component of the programme should not be redesigned in isolation. Instead, the findings of this study suggest that a more wide-ranging study of the educational basis for the client interface to the RAAF Health Promotion Programme is warranted.

Performance appraisal has been well established as an important management tool for improving individual and organisational performance, and has attracted considerable research interest over the past fifty years. Many previous studies of performance appraisal have been conducted either in laboratory settings, or have tended to focus narrowly on raters and/or the appraisal process, or of necessity have excluded from consideration the group dynamics prevalent in large organisations. Additionally, although it has long been recognised that the purpose of performance appraisal can affect ratings, little appears to have been done in situ on performance appraisal as a part of a complex personnel management system. One consequence of this approach has been a degree of uncertainty on the utility of laboratory and other findings to working appraisal systems. Moreover, previous examinations have focused on civilian organisations even though military organisations have an equally long history of using performance appraisal for a range of purposes. Using a sample (N = 577) of senior air force officers from three adjacent rank levels, this study examined the relationships between performance appraisal rating leniency, the perceived causes of leniency, and two personnel selection processes based on appraisal data. Rating leniency was perceived to be widespread, and was found to be associated with a lack of confidence (or mistrust) in several aspects of the performance appraisal system and related officer selection processes. While officer groups did not show any practically significant differences in perception of the prototype of the ideal commander (the leader), raters used a range of prototypes for estimating officers' promotion potential and suitability for command. Officers from one employment specialisation tended to stand apart in their view of the appraisal system and personnel selection processes, and the lower ranking officers surveyed tended to be more critical of the performance appraisal system and selection processes than were the higher ranking officers. In terms of selection process outcomes, 21.7% of officers were not satisfied with the management and leadership style of their commander, and officers at the lower organisational levels were found to be significantly (p<.005) more satisfied with their commander that those at the highest level. Satisfaction was found to be predicted by a multiple regression equation (R2=.72, p<.001), with the elements of the equation reinforcing the importance of a human-relations orientation for effective leaders. This study suggests that the behaviour of a working performance appraisal system can be predicted by established theory and that a model of system effectiveness may be possible, embracing rating errors, rating format, reliability factors (such as dyadic quality and period of observation), criterion validity of the appraisal instrument, and rater trust in the system. Additionally, this study suggests that upwards appraisal may be a useful input to the process for selecting leaders, if only to indicate which appraisal dimensions are perceived by subordinates to be important.

Between 1914 and 1945 the Australian air services, the Australian Flying Corps (AFC ??? 1914 to 1919), the Australian Air Corps (AAC ??? 1920 to 1921) and their successor, the Royal Australian Air Force (RAAF ??? 1921 to 1945), developed from a marginally effective air arm into a major air force with a continental strike capability. The interwar period saw a series of pioneering flights which not only laid the foundations for the air defence of Australia but also assisted in national development. Essential to the development of the AFC and the RAAF was the practice of air navigation. While much has been written on World War II RAAF operations, almost nothing has been published on the policy, training and practice of air navigation in support of wartime operations or the interwar period. This omission is addressed by the examination of air navigation in the AFC and the RAAF from the rudiments of World War I to the emergence of air navigation as a critical specialist function which culminated in its practice in World War II tactical and strategic air operations. It was the wartime development of Australian air power between 1939 and 1945, and the parallel practice of advanced navigation techniques, that underscored Australia???s contribution to the allied air offensive.

This thesis sets out to examine the proposition that Air Marshal Sir George Jones??? time as Chief of the Air Staff (CAS) of the Royal Australian Air force (RAAF) was both beneficial and detrimental to the Service but the benefits gained from his time in office outweighed the detriment. Sir George Jones served as CAS for nearly ten years (1942 - 1952). This was the longest continuous appointment of a CAS to date. Jones was CAS for most of the Second World War and it was during that time that the two events for which he is most remembered occurred, viz the controversy surrounding his appointment and his ongoing conflict with the RAAF Operational Commander (W.D. Bostock). In order to assess his impact on the RAAF, this thesis describes events and incidents that occurred while Jones was CAS. To compile this work, data was drawn from numerous sources including: interviews with family members and ex-RAAF personnel; official records maintained by the National Archives of Australia (NAA), the RAAF Historical Section and the RAAF Museum; Jones??? personal papers held by family members and the Australian War Memorial; and the papers of other RAAF officers and politicians held by the RAAF Museum and the National Library of Australia (NLA). Jones wrote a brief autobiography, which (together with other secondary sources) was used to ???fill in the gaps.??? This research shows that Jones??? time as CAS was far more eventful and filled with more conflict than he alludes to in his autobiography. He had no say in his appointment as CAS but his personality did not allow him to make the best of the situation with Bostock. Contrary to the views expressed in earlier works, Jones??? appointment was not a mistake but a deliberate move by the Minister for Air. The conclusion reached is that Jones??? time in office was beneficial to the RAAF. He presided over its growth to being the world???s fourth largest air force at the end of the Second World War. He oversaw its post war demobilisation and was responsible for planning the Service???s structure to meet the Australian Government???s needs during the early years of the Cold War.

In the year 1983/84, the Commonwealth Government decided to redevelop a RAAF airstrip at Tindal into a northern air base in NT. It would replace RAAF Base Darwin that was situated close to the coast and susceptible to both cyclonic weather and any 'enemy' sneak raid attacks. Tindal is located about fifteen kilometres south from Katherine on the Stuart Highway. A social survey conducted in the second half of 1983 formed the basis for SIA predictions that appeared in the EIS. These encompassed social impacts that would occur during the construction phase and later throughout the operational phase. Included among the predicted impacts on local residents was aircraft noise from military aircraft flying overhead and this was confirmed by a social survey conducted in 1994. Other predictions included the integration of a RAAF population with its own set of values into a conservative Katherine community. The social survey of 1994 asks the same type of questions as asked in 1983, and the two sets of answers are compared over time. A subsequent longitudinal analysis follows the structural development of the Katherine population/community. A group of 1994 respondents was found to have resided in Katherine in 1983 and cohort by cohort their state of affairs discovered. As Katherine developed into a regional centre the views of respondents toward the RAAF became more accepting and residual social impacts from the redevelopment phase were difficult to find.

The air campaign conducted by the RAAF in the North-Western Area during the Second World War has been largely ignored by historians yet it contributed significantly to the outcome of the Pacific war. This thesis sets out to discuss the campaign by considering various factors that impacted on the RAAF in the lead up to and during the course of the Pacific war and their relevance to the campaign. It looks at the way air operations were conducted in the North-Western Area between 1942 and 1945 and describes the role played by the flying squadrons based in the area. Using primary sources such as operational record books, documents and files at archives and libraries and interviews with veterans and experts the thesis found that the campaign was conducted in several phases. It started with the defence of Darwin. In keeping with overall allied strategy the RAAF then went on an offensive into what was then the Netherlands East Indies (NEI) using medium and heavy bombers and mine laying sea planes flying from bases in Australia???s north west. The NEI was vital to the Japanese war effort as a source of essential raw materials such as oil, timber, and rubber. To defend this part of their new empire the Japanese had amassed large military garrisons on the islands. The vessels used to transport troops and materials became the most important targets for the RAAF???s bomber squadrons. As General MacArthur???s forces advanced along the north coast of New Guinea the North-Western Area based units conducted raids into the NEI to deceive the Japanese into thinking an invasion would be launched from Darwin. As the New Guinea campaign gained momentum the RAAF???s task was to protect its western flank, to prevent the Japanese from moving troops and aircraft east to the Philippines. The thesis concludes the campaign was successful because Darwin was defended, it denied the Japanese vital materials for the conduct of the war and it kept hundreds of aircraft and tens of thousands of troops away from the allied advance.

This program of research was aimed at investigating a novel application of computer aided text analysis (CATA). To date, CATA has been used in a wide variety of disciplines, including Psychology, but never in the area of personnel selection. Traditional personnel selection techniques have met with limited success in the prediction of costly training failures for some occupational groups such as pilot and air traffic controller. Accordingly, the overall purpose of this thesis was to assess the validity of linguistic style to select personnel. Several studies were used to examine the structure of language in a personnel selection setting; the relationship between linguistic style and the individual differences dimensions of ability, personality and vocational interests; the validity of linguistic style as a personnel selection tool and the differences in linguistic style across occupational groups. The participants for the studies contained in this thesis consisted of a group of 810 Royal Australian Air Force Pilot, Air Traffic Control and Air Defence Officer trainees. The results partially supported two of the eight hypotheses; the other six hypotheses were supported. The structure of the linguistic style measure was found to be different in this study compared with the structure found in previous research. Linguistic style was found to be unrelated to ability or vocational interests, although some overlap was found between linguistic style and the measure of personality. In terms of personnel selection validity, linguistic style was found to relate to the outcome of training for the occupations of Pilot, Air Traffic Control and Air Defence Officer. Linguistic style also demonstrated incremental validity beyond traditional ability and selection interview measures. The findings are discussed in light of the Five Factor Theory of Personality, and motivational theory and a modified spreading activation network model of semantic memory and knowledge. A general conclusion is drawn that the analysis of linguistic style is a promising new tool in the area of personnel selection.
