This study was conducted to ascertain whether or not the opportunities for developing competencies in descriptive geometry needed by draftsmen in the Dallas -Fort Worth area are being provided in Texas junior colleges. Findings concerning the knowledge, skills, and equipment associated with descriptive geometry as it is presented in Texas junior colleges were compared with competencies in descriptive geometry that representatives of industry believe are important for successful draftsmen in companies in the Dallas-Fort Worth area. The purpose of the study is to compile information which will be of use to school officials and teachers in developing courses of study that will enable students to acquire the knowledge and skills needed for success in industry.

Assume AD+V=L(R). In the first chapter, let W^1_1 denote the club measure on \omega_1. We analyze the embedding j_{W^1_1}\restr HOD from the point of view of inner model theory. We use our analysis to answer a question of Jackson-Ketchersid about codes for ordinals less than \omega_\omega. In the second chapter, we provide an indiscernibles analysis for models of the form L[T_n,x]. We use our analysis to provide new proofs of the strong partition property on \delta^1_{2n+1}

Master of Science / Food Science Institute / Kadri Koppel / The pecan, [Carya illinoinensis (Wangenh) K. Koch], has a long history of cultivation and economic value. Knowledge of the compositional differences that exist between cultivars is important to the marketing of pecan varieties. The objectives of this study were to A) profile flavors for various pecans, B) determine flavor differences attributed to preparation method, C) find characteristics of acceptable pecan flavor, and D) evaluate sources of pecan flavor variation through chemical profiling. The flavor profiles of eight pecan cultivars ('Chetopa,' 'Giles,' 'Kanza,' 'Lakota,' 'Major,' 'Maramec,' 'Pawnee,' and 'Witte') were evaluated using descriptive sensory analysis under raw, roasted, and candied preparation methods. A trained panel evaluated samples for 21 flavor attributes. Five of these attributes differed significantly (p ≤ 0.05) between cultivars, while the preparation method significantly affected 17 attributes. Unique profiles were exhibited for each sample, with the 'Pawnee' and 'Lakota' samples displaying outlying characteristics for certain attributes. These results were used to select cultivars with varied but desirable pecan flavor. 102 nut consumers evaluated 'Kanza,' 'Maramec,' 'Pawnee,' and 'Witte' pecans under raw and roasted conditions for liking and flavor intensity. All samples were met with generally positive consumer acceptance, but three consumer segments were formed based on Overall Flavor Liking scores. Segment 1 was driven by cultivar differences, segment 2 by preparation method, and segment 3 by a combination of these factors. The largest drivers of consumer liking related to the roasting process. Chemical differences between cultivars under raw and roasted preparation methods were explored through fatty acid profiling (8 cultivars) and volatile olfactory compound profiles ('Kanza,' 'Maramec,' 'Pawnee,' and 'Witte'). Fatty acid profile variation could generally be attributed to cultivar differences, not changing much with the roasting process. Linoleic, palmitic, and stearic acids were correlated with more roasted-type attributes while linolenic acid was associated with dry, unfavorable attributes. 51 compounds with olfactory contribution were tentatively identified, 33 of which were found in all samples. Chemical profiles were unique to each sample, but some trends were apparent. The roasted 'Pawnee' sample, having many desirable flavor attributes, being met with great consumer acceptance, and having a composition that is associated with preferential attributes, may serve as a good standard for flavor.

The two main physical processes that underpin galaxy evolution are star formation and accretion of mass in active galactic nuclei (AGN). Understanding how contributions from these processes vary across cosmic time requires untangling their relative contributions. The infrared part of the electromagnetic spectrum contains a number of AGN and star formation diagnostics e.g. emission lines from ionised gas or polyaromatic hydrocarbons (PAHs), and the shape of the continuum. Despite the higher resolution of data from Spitzer's IRS spectrograph, separating out emission from star formation and AGN is carried out using limited spectral features or simplistic templates. In the first part of this thesis, I show how sophisticated data analysis techniques can make full use of the wealth of spectral data. I demonstrate how the popular multivariate technique, Principal Component Analysis (PCA), can classify different types of ultra luminous infrared galaxies (ULIRGs), whilst providing a simple set of spectral components that provide better fits than state-of-the art radiative transfer models. I show how an alternative multivariate technique, Non-Negative Matrix Factorisation (NMF) is more appropriate by applying it to over 700 extragalactic spectra from the CASSIS database and demonstrating its capability in producing spectral components that are physically intuitive, allowing the processes of star formation and AGN activity to be clearly untangled. Finally, I show how rotational transition lines from carbon monoxide and water, observed by the Herschel Space Observatory, provides constraints on the physical conditions within galaxies. By coupling the radiative transfer code, RADEX, with the nested sampling routine, Multinest, I carry out Bayesian inference on the CO spectral line energy distribution ladder of the nearby starburst galaxy, IC342. I also show that water emission lines provide important constraints the conditions of the ISM of on one of the most distant starburst galaxies ever detected, HFLS3.

As the largest gravitationally bound objects in the Universe, galaxy clusters can be used to probe a variety of topics in astrophysics and cosmology. This thesis describes the development of an algorithm to find galaxy clusters using non-parameteric methods applied to catalogs of galaxies generated from multi-colour CCD observations. It is motivated by the emergence of increasingly large, photometric galaxy surveys and the measurement of key cosmological parameters through the evolution of the cluster mass function. The algorithm presented herein is a reconstruction of the successful, spectroscopic cluster finding algorithm, C4 (Miller et al., 2005), and adapting it to large photometric surveys with the goal of applying it to data from the Dark Energy Survey (DES). AperC4 uses statistical techniques to identify collections of galaxies that are unusually clustered in a multi-dimensional space. To characterize the new algorithm, it is tested with simulations produced by the DES Collaboration and I evaluate its application to photometric datasets. In doing so, I show how AperC4 functions as a cosmology independent cluster finder and formulate metrics for a \successful" cluster finder. Finally, I produce a galaxy catalog appropriate for statistical analysis. C4 is applied to the SDSS galaxy catalog and the resulting cluster catalog is presented with some initial analyses.

This exploratory study investigated the strategies that eight older New Zealanders use to enable participation in day-to-day occupations that they need or want to do, in their homes and the community. The types of strategies older people use to overcome barriers to participation and manage limitations are not widely known or reported. Exploring strategies for participation employed by older people is important because the majority of older New Zealanders live in the community and their numbers are growing, and projected to reach 25% of the total population by the year 2051 (Ministry of Health, 2002). New Zealand’s Positive Ageing Strategy (Minister for Senior Citizens, 2001), advocates for a society where people can age positively, where they are highly valued and their participation encouraged. The literature relating to occupation, participation and health was explored, and provided some evidence that older people are developing strategies and, with some education, are able to manage their own health conditions. The assumption underpinning this study is that they are equally able to manage strategies for participation, particularly those devised by older people themselves. A qualitative descriptive methodology was used. The participants were selected following a presentation to a group of older adults and snowball recruitment. They were aged between 73 and 98 years old and were receiving assistance to live in community, which was taken to indicate they had experienced some limitation in, or barrier to their everyday activities, in response to which they might have discovered or developed coping strategies. Interviews were conducted in the participants’ homes, and analysed using a general inductive approach. Four main categories emerged; strategies for keeping me safe, strategies for recruiting and accepting help, strategies for meeting biological needs, and strategies for conserving resources. Overarching themes of managing and getting on with it, sprinkled with a sense of humour by some participants was present in the attitudes of many participants. The study revealed that this group of older people can and do use strategies to enable occupation in their everyday lives, which differ from those recommended by occupational therapists and other health professionals. This finding suggests that health professionals, policy makers and educators have much to learn from older people. The provision of help to older adults should take into consideration the importance of social interactions, not just the physical needs. There is a need for transport to be more readily available and affordable for older people to attend occupations that meet social needs. Health professionals complement the strategies developed by older people, and finding ways to combine the strategies should be developed. Listening to older adults’ current ways of managing and working with them to develop alternate, yet acceptable methods will provide a challenge. Health professionals should take a greater role in advocating for the social and transport needs of older adults. A self-management approach in education for older people, using peers and making use of existing education groups in the community and health system, is suggested. Education of those who engage with older people, such as carers, family, health professionals and community groups should include developing their skills in assisting older people to identify their strategies and developing strategies for the future.

This study was a cross-sectional epidemiologic evaluation of the clinical, sociodemographic, lifestyle and hospital utilisation characteristics of patients with diabetes, chronic obstructive pulmonary disease and chronic heart failure. Patients were enrolled in chronic disease management services of the Northern Alliance Hospital Admission Risk Program-Chronic Disease Management (Northern Alliance HARP-CDM Program). The program was established in accordance with the Department of Human Services’ (Victoria, Australia) initiative to intervene against increasing acute hospital demand by patients with chronic disease and complex needs. Amongst others, the Northern Alliance HARP-CDM Program provides services for patients with diabetes, chronic heart failure and chronic obstructive pulmonary disease. Patient cohorts with these three chronic diseases were the focus of this study. The Northern Alliance HARP-CDM Program catchment comprises of a culturally and linguistically diverse (CALD) population in the northern part of metropolitan Melbourne. Patients in this region mainly access acute hospital services at the Northern Hospital. The study sought to explore whether the CDM services enrolled patients whom based on their characteristics, fit the risk profile of the intended HARP-CDM target patient population. / The study cohorts demonstrated a CALD make up of above Victorian state averages. The majority (60%) were born overseas, preferred a language other English and were over 60 years old. In contrast to previously published studies, CALD did not demonstrate a significant contribution to disease control, quality of life or level of hospital utilisation. Place of residence for these patients showed clusters within some Local Government Areas. This has implications for service location, access and disease surveillance. Also, it presents opportunities for area targeted health promotion and prevention and overall service location. The majority (77%) of those with chronic heart failure had an abnormal left ventricular ejection fraction. The diabetes cohort was characterised by higher HbA1c (9%) than the target of less than 8%. Similarly the patients had greater than recommended waist circumferences (Males 106cm vs. 94cm; Females 106 vs. 80cm) places them at an increased risk of cardiovascular disease. For those with COPD, 42% had severe pulmonary impairment (FEV%predicted ≤ 40%) while 36% were moderate in the moderate category. / There was increased hospital utilisation with increasing age for those with COPD. With the exception of the diabetes cohort, there was no significant evidence as to the role of ethno-cultural factors in the study cohorts’ health, quality of life or level of hospital utilisation. However, ethno-cultural factors may contribute to the complexity of patient management processes and warrants further investigation. / Prior to enrolment in the Northern Alliance HARP-CDM Program, patients who could be considered high users of emergency department services made up 20% of those in the diabetes service, 43% in the COPD service and 50% amongst those in the CHF service. Similar figures for hospital admissions ranged from 20% for the diabetes services to 56% for the CHF service cohorts respectively. Although the diabetes service was the biggest of the three the majority of patients in the service had no previous history of acute hospital utilisation. Members of the diabetes service cohort were characterised by hospital utilisation rates lower than the Northern Hospital’s (ED: 34 vs. 72 per 100 patients, Admissions: 33 vs. 68 per 100 patients in the Pre HARP-CDM Period). Patients in the COPD service (ED: 115 Pre and 158 during HARP-CDM) and CHF service (160 Pre and 159 during HARP-CDM) had ED presentation rates per 100patients that were higher than the hospital’s (72 and 69). / The rates suggest the first 14 months of the Northern Alliance HARP-CDM Program were associated with increased hospital utilisation by patients enrolled the Northern Alliance HARP-CDM Program. The increments were greater than increases for the Northern Hospital for the same periods. Contrary to the intended goal of reducing acute hospital utilisation, the majority of the clientele did not fit the primary HARP-CDM Program criteria of high acute hospital users. But patients who were enrolled following previous hospital utilisation were well-targeted. However there are several patients who are likely HARP-CDM Program candidates who fall though the gaps between the acute hospital services and the program. / It is recommended the program and services increase enrolments and access for the target patient populations. There is a need for early intervention chronic disease management and health promotion. This service would cater for clients who by virtue of having a chronic disease are at risk but are currently not high acute hospital users. Such a service would free up vacancies in the Northern Alliance HARP-CDM Program, thus enabling increased intake and equitable access for the target patient population, especially those who fall though the gaps as referred to earlier. Funding for such a service is available through DHS. In light of strong evidence for exercise rehabilitation and its ability to positively impact patient outcomes, quality of life, survival and hospital utilisation, consideration needs to be given to this as part of the Northern Alliance HARP-CDM Program chronic disease management care model.

Human assessors are currently the best instruments for evaluating the sensory properties of both food and non-food consumer products. In the early stages of descriptive sensory panel training, a lexicon is still undergoing refinement and assessors are only beginning to understand the identities of sensory attributes and how to use the scale to communicate the intensity of sensations. To expedite training, the panel leader provides structure and feedback. Several statistical approaches have been proposed that indicate training status. In this thesis several approaches are reviewed, and a multistage process that involves scrubbing data, estimating parameters, reviewing fit, and exploring multivariate relationships is developed. The process reveals attribute misunderstandings, considers candidate training targets for subsequent training sessions, and explores data to better understand product properties.
