Chen, Yuanyuan. "Generating Nucleosomal Asymmetry in Saccharomyces cerevisiae: A Masters Thesis." eScholarship@UMMS, 2010. http://escholarship.umassmed.edu/gsbs_diss/500.
Full textAbstract:
There are two copies of each core histone in a nucleosome, however, it is unclear whether post-translational modifications on each molecule function redundantly or if symmetrical modifications are required to properly regulate gene expression. We tried to address this question by breaking nucleosomal symmetry and measuring its impact on gene expression. Our strategy includes re-engineering specific residues at the H3-H3 interface, generating pairs of mutant proteins, which were predicted by computational methods to form obligate heterodimers. Using S. cerevisiae as a model system, we tested the viability of strains with mutant histones, and analyzed the interaction between by co-immunoprecipitation from mononucleosome preparations. We also measured the changes of gene expression in the strains bearing single-tailed or tailless H3 heterodimers. The data suggested that the best computationally-derived H3 pair was frequently, but not exclusively heterodimeric in vivo. In order to obtain a more stringent H3 heterodimer, random mutagenesis was performed on four codons in the original computational design, and then genetic screening of the mutant libraries was performed.

Rosenbaum, Christopher D. "Herbal Marijuana Alternatives Investigation: K2 and Spice: A Masters Thesis." eScholarship@UMMS, 2011. https://escholarship.umassmed.edu/gsbs_diss/578.
Full textAbstract:
Background
Herbal marijuana alternatives (HMA), legal plant products adulterated with synthetic cannabinoid receptor agonists, represent a growing public health concern. Only a few case reports describe HMA and synthetic cannabinoid’s clinical toxicity. We describe an outbreak of HMA abuse primarily in the Midwest, the clinical presentation of HMA toxicity, and clinical and forensic testing.
Methods
During the course of ongoing surveillance for emerging drugs of abuse between November 2009 and August 2010, we retrospectively and prospectively identified a convenience sample comprising 81 cases of abuse of HMA products. Subject demographics, vital signs, lab results and urine were obtained (when available) and tested via gas chromatography mass spectrometry (GCMS) analysis. Samples of HMAs and synthetic cannabinoids were also analyzed via GCMS.
Results
HMA users were predominantly young males who inhaled HMAs. Analysis of their urine detected synthetic cannabinoid parent compound in one subject. GCMS analysis of synthetic cannabinoids established a reference library that confirmed the presence of synthetic cannabinoids in sampled HMA products.
Conclusion
HMA products were available in head shops, gas stations, and via the Internet. We have confirmed the presence of synthetic cannabinoids in these HMA products. The tachycardia, hypertension, agitation, anxiety, vomiting and hallucinations observed in this convenience sample are not readily explained by the presence of synthetic cannabinoids acting on CB1 and CB2 receptors. Further research must be done on HMA products and their abusers.

Find full textAbstract:
Differential operation of the Global Positioning System (GPS) has proved to offer superior positioning accuracy over unaided GPS. The nature of Differential GPS (DGPS) requires correction data to be sent from a reference station or a network of reference stations to the GPS
user in the field. Since it cannot be assumed that the GPS user is close to a telephone or data line, wireless communications technologies must be used to provide the GPS user with DGPS corrections. As very little crossover work has been done between the GPS experts and the data communications experts, there is a real need for a single
source of reference which brings together information on these fields and others which relate to DGPS service provision. The thesis reviews the communications options available for the broadcast of DGPS corrections, reviews the DGPS technologies available, and dimensions a DGPS system which would provide an easily-accessible and affordable DGPS service to GPS users anywhere in Australia. The dimensioned DGPS system is analysed in order to determine the positioning accuracies afforded by that system.

Full textAbstract:
This thesis outlines a research project that investigated the theory and practice of
employment relations in a large Australian company, Telstra.
The thesis takes its point of departure from the literature that has contended that there
has been a 'transformation' of American industrial relations (Kochan et al., 1986).
The literature review covers the debates that have developed around these authors'
contentions and also coverage of literature that is germane to the research project in
the areas of public sector reform and privatisation and employee participation in
organisational governance.
The research findings are presented in a case study divided into two pm1s. The first of
these parts investigates the context of employment relations at Telstra by investigating
the policy environment and technological change to which Telstra has been subject.
The second case presents the results of research into the conduct of employment
relations at Telstra.
The research finds that the environment has had a strong impact on employment
relations outcomes throughout Telstra's history. Environmental factors have
constrained performance to such an extent that moves to a more consultative and
pm1icipative approach to industrial relations within the firm have, for the most part,
been difficult to implement and have not met expectations.

The form exists long efter the content fades. (Pally, 1991 a: 11)
Peter Greenaway's feature films diverge significantly from traditional arthouse and
mainstream cinema. While their complex formal structure is supported by
intense intellectual content and structurally integrated allegory and symbolism,
they have very limited narrative structure or character development. Greenaway
has commented that "we expect content and narrative continuity of film and
could never conceive of shape and colour being responsible enough to provide
coherence" and that "the form exists long after the content fades," indicating his
deliberate divergence from other models. (Pally, 1991a: 11)

Full textAbstract:
World trade has developed in many ways, both multilaterally and regionally.
Consequently, many of the economies in the world have enjoyed rapidlyincreasing
economic growths through promoting trade-involved activities and
developing more fruitful trade patterns. At the same time, the trade patterns
have been focused on acceleration of economic benefits based on a
discriminatory scale within a certain region. Since the discriminatory
regionalism has been criticised to be inappropriate in terms of full
development of global welfare, the economies in the Asia-Pacific region
have come to develop the idea of forming a new international organisation,
named Asia-Pacific Economic Cooperation (APEC), with ultimate goals of
strengthening the GATT-based (now, WTO) multilateral trading system, and
open and free trade and investment in the region. Since the successful
inaugural meeting of APEC held in Canberra, Australia in 1989, the process
to achieve the goals has been accelerated, bearing productive fruits for
further evolution of the process.
Another productive fruit given from the evolution of APEC is a major
motivation for the bilateral economic relationship between Korea(ROK) and
Australia rapidly-developed from sharing the membership of APEC. Given
the ultimate goal of the APEC process, the two active member economies
have shared common interests in pursuing and promoting the process,
tightening reciprocal economic links and increasing two-way trade share in
the region.
The major purpose of the whole research is narrowed down to the
investigation of suggestions for further evolution of the APEC process and
bilateral economic relationship between Korea and Australia. With this aim,
the research problem has been developed as follows:
How should APEC facilitate a freer trade environment in the world
economy, and how should Korea and Australia promote the bilateral
economic relations as member economies in the APEC process? In this thesis, the approach to this problem is mostly relied on how to harden
the ties among member economies to achieve the process and to promote
the bilateral economic relationship in light of the progressive APEC process.
To examine the research problem more precisely, the following research
questions were developed in finding out potential solutions to the research
problem, they include:
1. What are main features of the world trade patterns today?
2. What are the purposes for the creation of APEC?
3. How far has APEC been evolved?
4. How should the member economies of APEC secure the future
evolution of APEC?
5. What are the implications for Korea from APEC?
6. What are the implications for Australia from APEC?
7. What are the suggestions for Korea and Australia to have closer
bilateral economic relations in APEC?
The data for this research were collected by using the elite interviewing
methodology, and validated as well as supplemented through the use of
three survey questionnaires. The research findings then were formulated
from a combination of the data gathered from the survey questionnaires and
interviews, which was analysed through the use of both quantitative and
qualitative research design. More specifically, the research strategies of the
analytic method and observation were employed to investigate the data of
this research project.
Regarding the research findings of this research, the indication was
investigated on the following four sections, they include:
1. motives, objectives and prospects of APEC;
2. suggested future directions of APEC;
3. the changing bilateral economic relationship between Korea and
Australia since the formation of APEC; and
4. likely future economic ties between Korea and Australia

Full textAbstract:
The aim of this study is to examine Australia's economic relationship with the European Union
(EU) countries since 1955 in order to develop a greater understanding of the current situation
between them. This is to be completed on two levels. The first being the actual trade relationship
between Australia and the EU and the second being the Australian perceptions of this trade
relationship.
The research problem to be addressed in this research is:
How have the development of regional groupings like the European Union impacted
on a country's trade? What role does the fear of exclusion play in this relationship?
The research questions that address this research problem are:
RQ.1) What has occurred in Australia's trade relationship with the EU countries since
1955?
RQ.2) How do Australians perceive Europe as a trading partner?
RQ.3) How have Australian perceptions of Europe affected economic relations with the
EU?
Chapter one introduces the background to this research, it outlines the research problem,
questions, objectives and the structure of the thesis.
Chapter two reviews the relevant literature to this research. The research is based on international
relations. A history of the emergence of the international economy is examined, and within this
processes of economic and political globalization are assessed. This provides an overview of the
processes which have led to the development of this research problem. The main theoretical body
to which this research contributes is then examined, this being the process of regionalisation as to whether a tri-polar world will be the norm or if it is a step toward globalization. An
examination of the European Union, a regional trade bloc, is then made. The further body of
theory to that on regionalisation is then examined being on customs unions, using the EU as an
example. An overview of Australia's position in the international economy and the implications
of these processes for Australia are then assessed. Finally the literature on Australian relations
with the EU is examined.
Chapter three outlines the methodological processes of this research. Qualitative analysis is to
be performed with some quantitative analysis. An historic approach is taken. Archival analysis,
surveys and interviews are used to collect the data. Procedures of data collection and analysis are
outlined and ethical procedures are considered.
Chapter four presents the findings of the research. The patterns of data pertaining to research
question one are first presented, these being the trade statistics between Australia and the EU.
Data pertaining to research question two are then presented. Firstly government perceptions of
Australia's relations with Europe are detailed. Secondly the portrayal of Europe by the media is
outlined. Finally the results of the surveys and interviews are presented giving Australian
perceptions of Europe.
Chapter five summarises the findings of the research and concludes the research questions and
problem. The variation in the reality of the trade pattern between Australia and the EU and the
Australian perception of relations with Europe are accounted for given the perception of the
Government and the Media. Implications of the research are then given for theory, and
suggestions are given for future research,

Full textAbstract:
This paper aims to examine several aspects of Quality Assurance in Australian manufacturing organizations. Firstly, it studies organizations that rely on
traditional methods of Quality Control for managing Quality, and one finding is that the management of Quality in Australian organizations has generally
not been a central strategy for organizational effectiveness. Secondly, it examines the benefits that effective Quality Assurance can give an organization. The results of the PIMS database were examined, and one
finding was that there was strong correlation between relative Quality and
business success. It was found that PIMS identifies Quality in terms of "attributes of importance to the customer", which is consistent with "conformance to requirements." Thirdly, the paper examines the implementation of a system of Quality Assurance in terms of Quality policy, Quality culture, managerial commitment
to Quality, organization and Quality planning, as many of these are prerequisites for the effectiveness of the Quality Assurance system. Fourthly, the organization with an accredited Quality Assurance system is compared with an organization with a non-accredited system. The Australian Standard AS 3901-1987 /ISO 9001-1987 is examined in some detail, and the influence of the Queensland Government State Purchasing Policy on an organization's decision to implement a Quality Assurance system is examined.

PROGRAMA DE SUPORTE À PÓS-GRADUAÇÃO DE INSTS. DE ENSINO
Com a análise das produções e das trajetórias acadêmicas de dois expoentes da Vanguarda Construtiva Brasileira – Décio Pignatari e Lygia Pape – o presente trabalho discute a relação entre arte e indústria a partir dos anos 1950. Ambos trabalharam como artistas, designers e professores universitários. Acreditavam que o artista moderno devia integrar-se à coletividade de diversos modos, incluindo a participação nos meios de produção e nas mídias de massa. Como docentes, iniciaram suas carreiras ministrando semiótica. Posteriormente, Pignatari caminhou para as teorias da literatura e da comunicação enquanto Pape se dedicou ao ensino de linguagem visual. Tanto um quanto o outro lecionaram em cursos de graduação e pós-graduação. Seus textos acadêmicos, embora pouco examinados em profundidade como parte do Projeto Construtivo, trazem importantes reflexões acerca da crise da arte na era da reprodutibilidade técnica, propondo saídas para este impasse. Por esta razão, são analisados os ideais expostos na tese de doutorado Semiótica e Literatura (USP-1973), de Décio Pignatari, e na dissertação de mestrado Catiti-Catiti, na terra dos brasis (UFRJ-1980), de Lygia Pape. Busca-se compreender seus posicionamentos perante o questionamento do belo como categoria central da estética, observando os reflexos da Semiótica de. C. S. Peirce nos temas abordados por Pignatari e as marcas da Fenomenologia de M. Merleau-Ponty no pensamento de Pape. Investigam-se, então, suas posturas em defesa da invenção artística, considerando as duas diferentes perspectivas sobre este conceito. Livros de W. Benjamin, M. Bense e M. Pedrosa estão entre referenciais teóricos centrais das duas pesquisas.
This research verifies the connections between constructive arts and industries after the 1950 s. Particularly, the work aims to inquire the productions and the academic trajectories of two important members of the Brazilian Constructive Vanguard – Décio Pignatari and Lygia Pape. Both of them were artists, designers and professors. In their view, the modern artist should contribute to industrial society in many different ways, because all creative activities were related. As college members, they began teaching semiotics. Lately, Pignatari dedicated his career to literature and communication theories and Pape became interested in visual linguistics education. It is worthwhile to mention that they were educators in graduation and post-graduation courses. Their academic papers discuss the art crisis in the age of mechanical reproduction, proposing ways to overcome this challenge. However, these texts were rarely mentioned as a part of Brazilian Constructive Project. Therefore, this investigation analyses Décio Pignatari s PHD Thesis called Semiótica e Literatura (USP-1973), and Lygia Pape s Masters Dissertation untitled Catiti-Catiti, na terra dos brasis (UFRJ-1980). Initially, their arguments lead to the questioning of the beauty concept as a central aesthetic category. In this sense, C. S. Peirce s semiotics impacts Pignatari s thoughts, and M. Merleau-Ponty s phenomenology marcs Pape s ideals. Lately, this work examines their claims for artistic invention, revealing two different perspectives on this concept. Books written by W. Benjamin, M.Bense and M. Pedrosa integrate their theoretical frameworks.

Dunleavy, June P. "Critical success factors in the implementation of telemarketing into organisations." Thesis, Queensland University of Technology, 1989. https://eprints.qut.edu.au/35802/1/35802_Dunleavy_1989.pdf.
Full textAbstract:
There has been much written in recent years about the value of telemarketing. This in turn reflects the rapid growth that the telemarketing industry both overseas and here in Australia is currently undergoing. In the telemarketing literature, there is little in the
way of empirical research, apart from Marshall and Vredenburg's (1988) study, to support the claims or prescriptions for success made by many telemarketing authors. Thus, there is a critical need for further research into the telemarketing field in order
to determine what is important in the implementation and use of telemarketing. The research question for this particular study is concerned with the way managers should implement telemarketing into their own organisations in order to achieve success. Based
on previous research and additional factors identified in the telemarketing literature, the hypotheses which were tested in this research were : the amount of planning undertaken before the introduction of telemarketing into an organisation; the level of specialisation of telemarketing representatives; the presence of key human resource elements (training, motivation, staff
performance measures) in a telemarketing operation;
the arrangement of telemarketing facilities within an organisation;
the use of scripts in a telemarketing operation;
the commitment of senior management in an organisation;
the amount of telemarketing experience of the managers/supervisors and staff of a telemarketing section; the level of integration of telemarketing within an organisation; and the type of product (tangible) or service (intangible) offered by an organisation.
Questionnaires were mailed to 595 known users of telemarketing in private sector organisations from both NSW and Qld. Of the 324 questionnaires that were returned, analysis on 214 totally completed questionnaires was carried out using crosstabulations
and statistics such as chi-square and kendall tau.
In general, the results of the research support all major hypotheses. However, there were
some specific elements such as type of incentive system, the use of outside help, price range of a product/service and field sales representatives working together with
telemarketing operators, that were not supported in the research. The results of this research have made a significant contribution to the body of telemarketing literature given the lack of previous telemarketing research. The research has confirmed certain findings of one previous research study, and has provided new and
conclusive research into other factors. This research is the first of its kind in Australia and therefore, the results take on added significance. As a result of this new research, organisations considering implementing telemarketing into their own organisations will be able to carefully plan for and manage the implementation of telemarketing by ensuring that critical factors identified in the research are assigned the necessary importance. By doing this, the probability of success
will be even greater.

McGrath, Pamela. "Chemotherapy : Treatment Experimentation or Illusion? : a Study into the Bioethics of Chemotherapy." Thesis, Queensland University of Technology, 1993.
Find full textAbstract:
The use of cytotoxic drugs, Chemotherapy, is considered by many a valid modality in the treatment of cancer. The use of this modality in the 1950's and 1960's led to considerable success in the treatment of a number of incurable and quickly lethal rare cancers. This gave rise in the 1970's to a high expectation that Chemotherapy would provide a much needed breakthrough in the search for a cure
for cancer. This optimism has led to a significant extension of the modality beyond the above known limits of successful use and created a climate which strongly supports this experimental application, although a small but increasing number of voices now challenge the legitimacy of this belief.
This research explores a number of ethical issues which now arise from the continued use of this treatment modality. The discussion will center on three issues. These will be, firstly, the integrity of the treatment modality, secondly,
the concerns about the experience of Chemotherapy on the individual and their family, and thirdly, the concerns involved in the public presentation of Chemotherapy and the lack of public debate. As a basis for understanding the ethical concepts used in this study into the Bioethics of Chemotherapy, a broad background of information on the relevant aspects of Normative Ethics is provided, at the beginning of this discussion. A study of the newspaper reporting of Chemotherapy is included to extend the
discussion of the third issue, that of the public presentation of Chemotherapy.In conclusion, an open ended, four step plan for action is recommended.

Williams, Joseph Patrick. "Upward continuation of magnetic intensity profiles." Thesis, Queensland University of Technology, 1986. https://eprints.qut.edu.au/35952/1/35952_Williams_1986.pdf.
Full textAbstract:
Upward continuation of magnetic data has been employed
by geophysicists for many years as a means of smoothing
the data prior to interpretation. Early techniques
utilised grid operators that were convolved with the
data to give upward continuation heights in units of
ono or two data spacings Data had to be collected
and interpolated onto a square grid for these operators.
Also large areas of data were lost around the perimeter
of the area using such techniques.
Much magnetic data is collected by aeromagnetic surveying.
This data is close spaced alone fJj_gh t lines '.'!hich
are often 10 to 20 data intervals apart, making
interpolation difficult and unreliable. It is possible
to avoid this problem by carrying out one dimensional
upward continuation the individual pro files,
assuming infinite strike length.
A technique designed by Bhattacharyya can be applied to
one dimensional upward continuation The method
involves the Fourier transform of data so that the
continuation is carried out in the frequency domain.
Continuation height is not restricted by sampling
interval, and no data is lost at the edges.
The application of Bhattacharyya's method to magnetic
intensity profiles is studied in this thesis with
particular emphasis on aeromagnetic data. The limitations of the assumption of infinite strike are
addressed by a study of computer modelling and field
tests., The field tests which wore conducted at
Kilkivan, Queensland, comprised an airborne and ground
magnetic survey, and a geological survey.
Geological mapping and susceptibility measurements
revealed that the magnetic sources were due to horizontal
volcanic flows and sediments lying unconformably on
a non magnetic basement. A series of simple computer models with dimensions approximating the volcanic roc~s showed that strike half lengths of over ten times the depth to top of model could be considered to have infinite strike lengths.
A series of 2.5D models with different depth extents showed that models may have a response.indicating an infinite depth extent at one observation level, but have a response indicating a finite depth extent at a higher level. It is concluded that drape flying may be a dangerous practice if the near surface magnetic sources are horizontal and of finite depth extent.
'l'he aerornagnetic survey occupied 8 flight lines,
5 kilometres long and 250 metres apart.
were: Survey heights
Flight 1 80 metres mean terrain clearance
Flight 2 11+0 metres mean terraj_n clearance
Flight 3 100 metres constant barometric height
Flight 4 150 metres constant baror0etric height
Flight 5 200 metres constant barometric height
110 test the method, Flight 1 \'las upward continued to
Flight 2, Flight 3 to Flight l+ and Flight 3 to F'light 5v
The upTiard continued results showed good acreement with
the measured data~ The worst matches were at the edges
of bodies of limited strike extent. The results were
better for smaller continuations.
It is concluded that the method of Bhattacharyya can
be applied to profile data even though there are some
limitations of strike length and depth extent for
horizontal bodies. If such limitations are suspected
computer modelling of the expected target should be
carried out.

Walker, Susan. "The effect of perceived social status on preschool children's evaluations of behaviour." Thesis, Queensland University of Technology, 1996.
Find full textAbstract:
One of the major tasks of the early childhood years is to learn positive and socially acceptable ways of interacting with others and much of this learning occurs within the context of the peer group. Positive peer interactions thus
make a substantial contribution to children's social and emotional development and rejection from the peer group in childhood has been linked to a variety of negative outcomes including early school withdrawal, delinquency and mental
health problems (Asher, Oden & Gottman, 1977; Kupersmidt, Coie & Dodge, 1990; Parker & Asher, 1987).
The perceived power of peer rejection as a predictor variable for future maladjustment has led to increasing concern by researchers to identify the factors involved in the establishment and maintenance of negative peer status.
In addition to such potential determinants as physical attributes, social cognition and communication patterns (Black & Hazen, 1990; Kurdek & Krile, 1982; Shaffer, 1988) behavioural characteristics appear to be strongly related to the development of peer social status. However, although initial behaviours serve to rapidly establish children's status within groups of previously unacquainted peers (Dodge, 1983), there is increasing evidence which suggests that, once status is established, behaviour change in itself may not be sufficient to improve social status (Mize & Ladd, 1990).
The present study arises from the premise that children's reputation may have an influence on the ways in which their peers both perceive and respond to their behaviour. In other words, a prior reputation may serve to maintain a
negative peer status even when behaviour is improved. The present study was therefore designed to examine the extent to which a preschool child's social status or reputation, once established, affects peer perception of his or her
subsequent behaviour. Of additional interest were possible sex and status differences in social information-processing.
Subjects were 62 children (35 boys and 27 girls) from three local Community Preschools. The children ranged in age from 4 years, 7 months to 6 years, 1 month of age. Prior to commencement of the main study socio-metric interviews were conducted consisting of a combination of limited choice
positive nomination and a three point rating scale.
Children were then assigned to one of five status groups: rejected, neglected, average, popular or controversial. Children unable to be classified were designated "other". In
conjunction with socio-metric testing, teachers were asked to complete a twelve item Teacher Assessment of Social Behaviour Questionnaire (Cassidy & Asher, 1992).
After completion of sociometric testing children took part in individual interviews in which they were presented with information regarding the liked or disliked status of a hypothetical same sex peer and reputational information in
the form of social information pictures depicting the target child engaged in social interactions. From this information children made inferences about the hypothetical peer's general disposition by rating the likelihood that he or she would behave in either pro-social or antisocial ways. Children were then presented with two types of hypothetical situations, other involved and self
involved.
The other involved hypothetical event consisted of presentation of a picture showing the same sex target peer and another same sex child involved in a conflict situation. The self involved event consisted of a hypothetical situation involving the subject and the target child in which the intentions of the target peer were ambiguous but a negative outcome for the subject resulted. Children were asked their perceptions of the target peer's involvement in the hypothetical events along the dimensions of locus of control, intent and stability for the
other involved event, and locus of control and intent for the self involved event. Presentation order of popular versus unpopular target peer and self involved versus other involved hypothetical events was counterbalanced across subjects. The results clearly demonstrated that preschool children's evaluations of the target peers varied as a function of the target child's reputation and the subject's
gender. Overall, children made significant distinctions between popular and unpopular peers both when making dispositional evaluations of the target peer and situational attributions about the target child's involvement in the hypothetical events. In contrast to expectations, no status differences in social
information-processing were found.
Sex differences in the use of reputational information were evident both for dispositional inferences and situational attributions. Specifically, girls made greater distinctions between popular and unpopular peers than boys both when
making inferences about the target child's disposition, and when making attributions of intent. Relative to boys, girls rated the popular peer as more friendly, more helpful and more liked and the unpopular peer as more likely to get angry, fight and hurt others. Girls also rated the unpopular peer as acting intentionally more often than boys and were less likely to ascribe intent to the popular peer.
Sex differences were also observed for teacher ratings of aggression, disruption and sociability. Teachers rated boys more highly on the dimensions of aggression and disruption while girls were rated high on sociability. These dimensions were also significantly correlated with children's evaluations of the target peer. Specifically, boys rated as highly aggressive or disruptive were likely to make more negative evaluations of a popular peer on pro-social items whereas sociable children of both sexes made more positive evaluations of an unpopular peer's involvement in a self involved negative event. Overall, these results replicate previous research (Cirino & Beck, 1990; Dodge, 1980; Hymel, 1986; Waas & Honer, 1990), indicating that children vary their perceptions of and explanations for behaviour as a function of the liked or
disliked status of the target peer.
Additionally however, the present study extends previous research efforts by demonstrating that reputational bias interpretations of behaviour is present in a much younger age group than that previously studied.

Full textAbstract:
A review of area teaching sequences indicated general agreement about
what concepts need to be taught, the sequence in which to develop
these concepts and the sorts of teaching strategj es that need to be
employed.
Existing research seemed to indicate a disparity between recommended
teaching practices and what is actually happening in classrooms,
however, actual research into children's understanding of key area
concepts and information about the process and strategies children
employ in solving area problems was limited .
This s tudy was designed to address this deficiency . The study was
designed ito provide i nsights into upper primary students' knowledge
and understanding of important area concepts. The study had three
areas of focus; pre-formula area concepts, the formula for the area of
a rectangle and the formulas A = S x S and A = b x h -t 2, both of
which can be derived from the formula for the area of a rectangle.
Nine area tasks were developed . The tasks were designed to give
students the opportunity to display behaviour from which mental
mechanisms can be inferred. The tasks formed the basis of a clinical
interview . All students were initially presented with the same
tasks, however, subsequent questioning varied according to the 11Jay
children responded to the initial questions. The interviews were
conducted using twenty year seven students. The i nterviews were of
approximately twenty mi nutes duration.
t ape recorded for later analysis. The information collected from the i nterviews indicated that
child1ren' s understandi ng varied quite significantly from one concept
to another . On the whole, children's understanding of pre-formula
area concepts was quite good . The one aspect of pre-formula area
concepts that caused difficulties was s tandard uni ts. Chi.ldren 's
knowledge and understanding of standard units was noticeably
inadequate.
A majority of students had a sound understanding of the formulas for
finding the areas of rectangles , squares and triangles . Most
students recognized that the formula A = b x h + 2 was similar to
halving the area of a rectangle; however, students were initially
reluctant to accept that the rules A = 1 x b and A = S x S were
relatEid.
The study identified several common gaps and misconceptions . It was
doubtful whether these gaps and misconceptions could be attributed to
students' inability to come to terms with overly difficult ma t e r ial.
It seHmed more likely that the gaps and misconceptions were linked
with a t eaching sequence that tends to rush i nto formulas , teachers'
inability to identify and diagnose students' errors and
misconceptions, students needlessly fragmenting and compartmentalizing
similar i deas and students having only limited opportunities in which
to test, extend and apply their knowledge and understanding
meaningfully.
The study concluded with a list of recommendations that were i ntended
to help overcome some of the gaps and misconceptions that this study
identified .

Full textAbstract:
The objective of the research program presented in this thesis
was to develop a simple and specific immunological assay for
the measurement of rnolecilar fr agments produced during the
enzymatic lysis of f i brin. This would establi sh a significan t
contribution to the laboratory diagnosis of disseminated
intravascu lar coagulation and thromboembolism .
iii.
Lysis of blood clots i n t he circulation (fibrinolysis), produces
unique mo lecular fragments which are detectable i n t he blood
plasma. These fragments are unique as a resu l t of y - y
cova l ent crosslinki ng between adjacent f ibrin molecul es and
are not presen t on the parent mo l ecule fibr i nogen . D dimer
(D-D) is t he basic fragment and i s freque ntly compl exed non covalently
wi t h fragment E to produce D dimer E. Other
fragments also resu l t from t he lysis of crosslinked fibrin
and i nclude Y-D , Y-Y, X- Y and h i gher molecular weight
fragments up to and exceeding 106 daltons . Present immunol
ogical me t hods cannot different i ate these y- y f ragments
from fibrinogen or its deriva tives wh i ch a r e pre sent in the
absence of intravascular blood c l otting .
During t he past f i ve years several workers in Britain, Europe
and Amer i ca have reported attempts to produce antibodies tha t
will react with f ibrin derivatives and not fibr i nogen or its
degradation products . The resu l ts of these st udies have been
d i sappoi nt i ng because they have f ailed to totally remove
crossreactivi ty with f i brinogen .
In this present study , a monoclonal antibody specific for
crosslinked fibrin has been developed . This antibody has
been used in both enzyme immunoassay and latex agglutination
procedures for the measurement of crosslinked fibrin
derivatives (measured as D dimer equivalents) in proven cases
of dissemi nated intravascu lar coagulation and tnromboembolism.
Low levels ( <240 ng/ml ) of crosslinked fibrin derivatives
were fo und in normal subjects . In contrast, significantly
elevated levels were detected in all proven cases of
d i sseminated intravascular coagul ation and deep vein thrombosis
and in the majority of cases of proven pulmonary embolism . The presence of crosslinked fibrin derivatives in disseminated
intravascular coagulation was also demonstrated using a
sodium dodecyl sulphate (SDS) pol yacrylamide gel electrophoresis
technique . Plasma levels of crosslinked fibrin
derivatives were also used to assess the predictive value
in the diagnosis of deep vein thrombosis and pulmonary
embolism in patients subjected to venography and l ung scan .
The immunoassays developed and described in this thesis are
rapid , speci fic and sensit ive . They provide the basis for
clear distinction between the breakdown products o f
fibrinogen and fibrin which is essential in the accurate
evaluation of thrombotic disorders.
These novel assays therefore have a unique diagnostic
potential which has already attracted significant international
interest.

Full textAbstract:
The effect of age, age related maculopathy (ARM)
and its precursor pre-age related maculopathy (PARM)
on the visual field for both white and coloured
stimuli was investigated. The visual fields were
plotted using a modified Goldmann perimeter. The
visual field was significantly reduced in size for
the white and short wavelength stimuli for the three
age groups tested. The decrease occured primarily in
the middle age group. There was no decrease in the
visual fields for the middle and long wavelength
stimuli for any of the age groups. The ARM subjects
showed no difference in visual field size for any of
the stimuli when compared to age-matched normal
subjects. The visual fields for the PARM subjects
showed no difference in visual field size for the
white, short wavelength and long wavelength
stimuli,however a decrease in visual field size for
the medium wavelength stimulus when compared with
age-matched normals was noted. The effect of pupil
size on the visual field size was also investigated.
However due to the restricted range of pupil sizes in
our subject base no definite conclusions could be
made.

Dinh, Kate H. "Sentinel Lymph Node Biopsy in Elderly Patients with Intermediate Thickness Melanoma: A Masters Thesis." eScholarship@UMMS, 2015. https://escholarship.umassmed.edu/gsbs_diss/778.
Full textAbstract:
Background: A landmark study suggested that wide excision of intermediate-thickness melanoma with sentinel lymph node biopsy (SLNB) and subsequent completion lymph node dissection (CLND) for regional disease may improve prognostication and disease-free survival (DFS) compared with those undergoing wide excision alone. However, these benefits were relatively small and not associated with an improvement in disease-specific survival (DSS). It remains unknown if SLNB and subsequent treatments are beneficial in elderly patients who have a decreased overall (OS) due to other causes.
Methods: Adults ≥ 70 years of age, who underwent surgical intervention for intermediate-thickness cutaneous melanoma from 2000-2013 were identified from a prospectively-maintained database. Clinicopathologic variables measured included age, gender, anatomic site, histologic type, tumor thickness, ulceration, receipt and result of SLNB, completion of CLND, OS, and DFS.
Results: Ninety-one patients underwent excision of an intermediate-thickness melanoma. Forty-nine patients (54%) received a SLNB. Seven of these biopsies (14%) were positive, and five patients went on to receive CLND. Five-year OS was 41% in patients who did not receive SLNB and 52% in patients who did receive SLNB (p=0.11). DFS was similar between groups independent of receipt of SLNB.
Conclusion: Among elderly patients with intermediate-thickness melanoma, patients who received SLNB had similar 5-year OS and DFS compared with those who did not receive SLNB. Routine SLNB for intermediate-thickness melanoma patients may not significantly change outcomes for this age group, and clinical decision-making should consider individual patient comorbidities and goals of care.

Full textAbstract:
This study develops a model (i.e., secondary values selection process - 2VS) to describe how values shared by individuals (i.e., secondary values) contribute to the creation of meaning and interpretation in organisations. Elements of the model are identified through exploration of two bodies of literature (a) cultural approaches to organisational studies, and (b) theories of evolution. Incorporated within the model are observable elements that support analysis and evaluation of the 2VS. Outcomes of the study are (a) development of a more complete understanding of the Selection Process in organising and (b) creation of a mechanism for cultural analysis of organisational settings.

It is important, if we are to know each other, that you also know my alphabet, because from the moment I hear your name - and ever after - I will associate you with a colour. Do not be offended; without it I would have bugger all chance of remembering what your name is. And please do not assume the colour of your name is in some way a reflection of your character: it is nothing more than the outcome of a
struggle between the letters that make it up, of which the first will almost always win. Like, I have this friend, Colin, and his name is pink. And when I told him this he looked bemused and said, but he hated pink; what did this say about him? And I hid my irritation with a smile
and explained it said nothing about him, other than that his name was made up of a combination of letters that when placed in that order looked pink. I said if he was a Graeme, he would be black-blue with green; if he was a Graham, he would be black-blue with brown; but he
was a Colin, and so he was pink, and nothing short of a deed poll would change it. Of course not everyone reacts like Colin, stodgy old stick that he is. It would be easier if they did. Once, when I was in Europe, my alphabet
became so strong I could not write postcards. Every time I tried, the colours of the words would clash, and I could not go on. And my 1st boyfriend, who was with me, said I should go with the urge to make the colours match, that by doing so I would be saying what I really wanted to. He was always saying things like that, and most of the time I
ended up believing him. But not even the Ecstasy we were on could convince me he was right that time. It was all I could do not to say: for Christ's sake, the colours are arbitrary! Months later, when I was coming to terms with the end of our relationship, that incident seemed to sum up everything that was wrong with him and me. I almost passed my current lover up because of that. My alphabet was
the first thing he knew about me, and the envy with which he spoke of it annoyed me. Then on Valentine's Day he sent me a song, with the lyrics transcribed in my colours, and I began to understand why he wanted to see what I saw. For all the hours he put in, he could not capture how my alphabet looks to me, the endless variation triggered
by the arrangement of its letters into words. For the more I look at a word, the more colours I see. In the first instance, I see one. Within half a second, I see other colours come to life, each struggling for recognition. Within half a second more, I see the colours separate, each
letter standing on its own. But as long as they are a part of a word, some of them will always be screened: 30% for this one, 10% for that. Being a sometime copywriter, this makes sense to me. I like it to make sense. I like it to stand up to scrutiny, even when I cannot explain it. One day someone asked me: why don't all your
colours turn to brown? And I thought for a moment, for it had never occurred to me to look at it this way, but in the end all I could say was: when you look at a rainbow, do its colours all turn to brown? I cannot tell you why, but every letter, every word has a colour all its own, and every number too. Look, I'll show you: 0 is the colour of water; 1 is white; 2 is dark purply blue; 3 is orange; 4 is purple; 5 is pink; 6 is yellowy lime; 7 is orangey brown; 9 is dark blue; 10 is red and so on -after 10 they tend to be a combination of the numerals that make them 2 up. So why is 10 red, you ask, instead of white and the colour of water? Well, again I cannot say, except the word 'ten' is red, and sometimes the colour of a numeral and its spelling influence each other. You see, I might be unusual, but I am not immune to learned association.

Full textAbstract:
Drawing upon data from published and unpublished sources, this thesis examines the classical guitar in Australia during the years spanning European settlement to the early 1970s. The significant factors, events and individuals that shaped the early history of the instrument in this country have been documented and examined, and form the central focus of this investigation.
This study begins with an examination of the origins of the guitar in Australia during colonial times. Following this, against the background of international events and influences, the lean years of classical guitar activity in Australia between 1900 and 1945 are examined. The study then focuses on the rise of classical guitar activity that occurred in this country after the Second World War, and in particular the work pioneered by Len Williams and guitar societies throughout Australia.
In this study a special focus has been given to the 1960s: a decade that witnessed a flourishing of classical guitar activity throughout Australia. The latter part of this thesis
investigates the critical developments and shifting attitudes that led towards the acceptance of the classical guitar as a serious instrument of performance and academic study in this country. The conclusion of this study identifies and examines three major periods of activity, highlighting the geographical, cultural and educational factors that have influenced the history of the classical guitar in Australia during its formative years. Finally, recommendations are made for further study into Australian classical guitar culture after 1970, and in particular the specialist and high growth areas of guitar composition and guitar construction.

Full textAbstract:
The Filipino community is one of the most rapidly expanding non-English speaking background communities in Australia: a young vibrant community, well educated and qualified, possessing exceptional English language proficiency.Because of a significant proportion of Filipino-Australian intermarriage, and a large family-oriented immigration trend, many unique cross-cultural and social issues have emerged in the Filipino community.
An examination of the literature revealed that many aspects on Filipino immigration to Australia are disproportionately studied, leading to the
perpetuation of stereotypes and myths. There has been a tendency to focus on Filipino wives (not women), without reference to Filipino men, or to cultural values and experiences of Filipino families. The main objective of this study was to provide a broad sociological survey of Filipino immigrant families and latter
generations in Australia.
This study analysed the amalgamation of Filipino and Australian cultures
through diverse family structures, and highlighted both differences and commonalities. The recognition of Filipino immigrants as active agents in their
own settlement, provided an understanding of the adaptive reconstitution of Philipino culture through family interactions, child-rearing practices, employment
and intergenerational experiences. An historical and cross-cultural perspective has employed to analyse the development of Filipino immigration to Australia
and the socio-cultural issues affecting Filipino families.

Full textAbstract:
This thesis is a study of the weathering of stressed polyamides using a multidisciplinary approach.
The chemistry, physics, morphology and mechanical properties are considered in relation to the effect of natural stress weathering of oriented and unoriented Nylon 6. The sample morphology was studied using x-ray diffraction, differential scanning calorimetry and scanning electron microscopy. It was found that the injection moulded samples had differing surface
morphologies according to the temperature of the mould.
Stress chemiluminescence studies showed that there was a difference in the depth of the temperatures of the injected moulded samples. These slight differences in morphology were found to give the samples
differing weatherability under load. Both the unloaded and loaded indoor samples showed negligible deterioration in mechanical properties. Applied stress was found to induce crystallization. No chain scission was apparent for either the loaded or the unloaded samples in the absence of sunlight. The loaded and unloaded injection moulded samples exposed outdoors showed a significant increase in degradation through loss of mechanical properties and the build-up of oxidation products. ESCA and FTIR analysis showed that the outdoor environment induced a significant amount of chain scission in the samples. This was found to be greatest for the loaded samples where the load and environment acted synergistically to increase the amount of degradation.
Stress chemiluminescence showed that the loaded outdoor samples suffered the greatest amount of chain scission which appeared to be proportional to the UV dose.
The stress weathering of the oriented (monofilaments) showed a slight increase in the amount of degradation incurred by the samples exposed outdoors.
It appeared that the load applied (15% of the failure stress) was insufficient to induce sufficient stress on the tie chains to accelerate the degradation process.
An important aspect of this study is that the morphology differences induced in the samples by variation in the injection moulding conditions was taken into account. The scatter of results for the separate batches was much less than has been reported by others for natural weathering trials.

Full textAbstract:
Various techniques for accelerating mature flavour
development in Cheddar cheese were compared. Control
cheese ( c) was manufactured by using Streptococcus
cremor is AM2, a starter used in normal commercial
manufacture. A combination of S. cremoris AM2 and
Streptococcus lactis C2 Lac- Prt- mutant was used in the
manufacture of test cheeses (M). §._. lactis C2 mutant was grown in glucose broth at 30°c and pH 6 .O for 16 hours, followed by concentration and diafiltration to 1011cfu mL - 1 using microfiltration equipment. The control cheesemilk was inoculated to 6x107 streptococci pe mL with S. cremoris AM2 and the mutant vat cheesemilk to 2x109 per mL with a combination of ~ cremoris AM2 and ~ lactis C2 mutant. The starter population in cheese containing mutant starter was 100 times that in control cheese (1010 compared to 10a). Cheeses were also made with added bacterial neutral proteinase (Neutrase, N) and stored at a0c (a) and 15°c ( 15) for 32 weeks. This resulted in cheese being subjected to the following treatments: ca (control), C15, CNa, CN15, Ma·, M15, MNa, and MN15.
Cheddaring times were slightly reduced and milling
acidities slightly higher in the vat . containing mutant
starter. However the composition of all cheese was
satisfactory. Bacteriological counts, proteolysis,
rheological properties and flavour development of these
cheeses were monitored at regular intervals throughout
maturation. The order of the effectiveness of the
treatment in accelerating ripening was MN15, >M15,>
CN15,> C15,> MNa,> Ma,> CNa,> ca. Cheeses from these
treatments attained the characteristics of control cheese
stored at a0 c (Ca) for 6 months after 1.4, 1.7, 2.0, 2.6, 2.8, 3.2, 4.3 and 6.0 months respectively. Cheese quality was not adversely affected except for bitterness in CN8 cheese and overmaturity in CN15 cheese late in the storage period. The possible mechanisms and relative merits of the various treatments are discussed with special reference to an "active role" theory of starter bacteria in flavour development.

structures is discussed briefly. Modern material types and design methods are
discussed. Elements of good patterning are discussed and supported by finite
element sensitivity study. Ideal fabric material properties for serviceable
structures are listed. The property of primary focus for the testing undertaken is
ultimate biaxial strength. Young's moduli, Poisson's ratios and shear modulus are
also properties of interest which are dealt with briefly. Styles of biaxial testing
are discussed. A cylindrical biaxial tester has been designed and constructed and
a proving testing program conducted. Methods of extraction of material

Find full textAbstract:
This thesis reviews the post-war Australia-Asia relationship, while investigating how and why Australia has come to try to identify itself as an
Asian country. In this context, it examines how the media represent Australia's role in the Asia-Pacific region and the process of the 'Asianisation' of Australia, particularly focusing on the role of newspaper
coverage. The Australia-Asia relationship has been problematic because of a particular history - in particular Australia's strong attachment to Europe.
In the midst of a movement of self-definition, Australia seems to have been
caught up with an identity crisis since realising it geographically belongs to Asia but mentally belongs to Europe. In this context, I examine the role of
the media in promoting awareness of Australia's place in Asia. I investigate the coverage of the 1993 APEC forum in The Asahi Shimbun (Japan), The New Straits Times (Malaysia), and The Australian (Australia) as case
studies for discursive analysis. I also conduct content analyses of these newspapers. This analysis reveals that the media exercise their hegemonic role in society through omission of alternative views and/or reproduction of preferred versions of Australia's role in Asia, particularly through the process of Asianisation. It also shows that the cultural perceptions of Australia held by Japan and Malaysia, as revealed in the focus newspapers, differ considerably from those which predominate in Australia.

Full textAbstract:
Although many prior studies have focused on strategic marketing plans, there is no literature addressing the strategic marketing plans for Taiwanese and Australian
trading companies. This thesis concentrates on building a general framework which could help Taiwanese and Australian trading companies to develop strategic
marketing plans to expand their businesses. Thus, this thesis addresses the research problem: How do Taiwanese and Australian trading companies develop strategic
marketing plans for each other's country? This research in reviewing the relevant literature regarding international trade (including gains theory and product life cycle theory), international marketing (the
nature and scope of international marketing), globalization, international strategic marketing plans, export entry strategy, trading companies and culture, formulated three research questions:
RQ 1: How do Taiwanese and Australian trading companies develop strategic marketing plans?
RQ2: How do Taiwanese and Australian trading companies implement strategic marketing plans?
RQ3: How does knowledge of a target country's business culture affect strategic marketing plans?
Data was collected by using the case study methodology, with one pilot case study conducted in Brisbane to refine the research protocol and procedure. In the major
stage of data collection, exporting or marketing managers in four Australia trading companies were interviewed in Brisbane and in four Taiwanese trading companies in
Taipei. Then the data was analyzed by using case descriptions, cross-case analysis and
explanation building methods. This research found both Taiwanese and Australian trading companies have similar
processes on exporting, only with minor variables which were different due to business culture and duration of operation. Taiwanese trading companies tend to have
longer duration of strategic marketing plans than Australian ones. Both Taiwanese and Australian trading companies attempt to focus on establishing relationships with their distributors or importers. However, only found in Taiwanese cases involve in third country trade. On the basis of research findings, a conceptual framework was
built to assist Taiwanese and Australian trading companies to develop strategic marketing plans. This research contributes to knowledge because it is arguably the first to: • compare the current position of some Taiwanese and Australian trading
companies,
• compare their strategic marketing processes,
• compare how their business cultures influence strategic marketing plans, and
• use case study research methodology for this sore of international comparison.

The hypothesis was sustained that The Independent Monthly played a notable part in media opinion leading and media agenda-building, the process in which the "careers" of mainstream news events may be recognised in different stages of development at different media sites.
Since journals of opinion came into being at the beginning of the 18th Century their role has been to supplement and re-negotiate the largely reportorial function of the mainstream media, supplying views rather
than news. They have always targeted the gatekeepers and commentators of the established media. The line of descent of the The Independent Monthly was traced f ran the earliest British and American journals, one
of which, Nation, founded in 1865, saw itself as the "external conscience of other publications" to more recent predecessors in Australia. Interviews in depth were conducted with the founder editor, Max
Suich and several of his most eminent collaborators. Content analyses of the journal were undertaken and the editorial and financial strategy devised for its launch and subsequent three years of operation closely
scrutinised. Readership surveys were examined and extrapolations made. Some aspects of the study were also scrutinised from the viewpoint of mass media theories of DeFleur and Ball-Rokeach, among others. The Independent Monthly was deliberately aimed at the segment of
potential readership identified by Huqh Mackay, a leading social
researcher consulted in advance of its launch, as "the
information club". Mackay believed there was a national pool of no more than 100,000 individuals who were assiduous collectors of news and information. either because it empowered them in their occupational roles or enhanced their social standing. The conclusions of the study suggest that the The independent

Change is now recognised, not as an aberration of
organisational functioning, but as a central process to be explained. Moreover, how change is communicated
determines how it is experienced. A common way of
attempting to involve all people in an organisation in the change process is via the constitution of a steering committee, charged with the task of guiding the organisation successfully through to the desired vision. This thesis seeks to study the communication functions of this team, drawing from behavioural, management, organisational and communication
literature. In light of the complexity of the theoretical
landscape, this thesis adopts an eclectic perspective with its primary purpose being to bring theory to bear on practical issues. Whilst the change team is central to change, little research exists which has explored the communicative aspects of the steering committee. Therefore this study adopts a case study approach to enable a flexible, open-ended research process.
Two organisations were involved: the State Department of
Lands which was going through 'Job Redesign', and the
Commonwealth Department of Health, Housing and
Community Services which had been through an
organisational restructure two years prior.
The thesis concludes that, whilst acknowledging the
complexity of organisations and recognising that different variables are at work in any situation, there appear to be several fundamental challenges which impact on the change team. These are: the effect of power, politics, and conflict on the change process; the commitment of management within the organisation to the proposed changes; staff participation and resistance; the communication strategy used by the team during the process, in particular, how the change is announced.

Full textAbstract:
A key issue in assessing Australia's compet1t1veness is the extent to which Australia's arbitration system has produced an industrial relations climate that promotes decentralised policies that are designed to lead to greater flexibility and productivity at the workplace. This issue will be examined by this thesis by focusing on union acceptance of enterprise bargaining. A survey of union officials in Queensland is used to test acceptance and commitment to enterprise bargaining and its perceived ability to deliver increased flexibility and productivity at the workplace level. The results of the survey show that union acceptance of enterprise bargaining is related to workplace size, industry type and management approach. The analysis of the research findings indicate the need for a more skilled union presence at the workplace, focused on enterprise needs. Trade unions have an opportunity to capitalise on the opportunities offered by enterprise bargaining to enhance the role of unions and their relevance to union members.

In examining relational communication exchanges, one aspect that constantly
comes to the fore is the construct commitment. Without commitment these
exchanges would seem to have a lesser chance of developing into lasting
systems. One example of a relational communication system is the
employee/employer relationship found in many organisations.
Organisational commitment has been the subject of many studies and in
furthering research into this form of commitment many measuring instruments
have been developed and tested. Of these instruments, one that has achieved
widespread acceptance is the Mowday, Porter and Steers Organisational
Commitment Questionnaire (OCQ). Although the OCQ was designed in the late
1970's it is still used in many current studies, despite developments in the
literature that have made it if not obsolete then at least obsolescent.
One of these developments has seen the involvement component of
organisational commitment gain increasing prominence. It is this involvement
component, and ways of measuring it that reflect the current literature, which
forms the basis of this study

Business Process Reengineering (BPR) has only recently been added to the management theory vocabulary. It was first introduced in the late 1980s with the release of works by Michael Hammer and Thomas Davenport. The term was received enthusiastically by a receptive and eager management consultancy movement and packaged as a new "breakthrough" concept enabling dramatic improvements in business performance. Since its first introduction,
there have been many reported failures of BPR projects, with many commentators reporting failures as high as seventy five per cent. The dynamic systems that shape and influence markets are complex and include, "inter alia" government policy, technology, world economies and their changing interrelationships. It is this richness and complexity that shapes the rules of competition. Set against a back cloth of increased competition emanating in part from emerging economies of South East Asia, Australian secondary manufacturers, (as distinct from primary industries) are faced with the need to maintain or improve their competitive positioning. As a consequence, many will be faced with a requirement to realign their internal organisational structure and strategies, with the demands of their markets, Business Process Reengineering has been offered as a complete
and cogent theory that if implemented correctly will deliver stepped improvements in business performance.
This thesis explores the historical context within which BPR is seen as a natural and unavoidable consequence of world events. The paper goes on to describe and define BPR, and examines the nature of "strategy" and how BPR and strategy fit together. To complete the
description of BPR, the paper explores the literature on "process" . Having described the historical context and defined the meaning of BPR, the paper goes on to offer reasons, based on research, why there is such a high rate of BPR failure as reported. The research
design involves the use of a self administered questionnaire,
employing Likert scaling and designed to test for the level of
understanding that exists within the sample, of Business Process Reengineering concepts. The questionnaire also probes for the existence of common success factors and relationships between changing competitive environments and the choice of BPR as a competitive repositioning process. The sample has been restricted to manufacturing companies who are members of the Queensland branch of the Metal Trades Industry Association, and who are located in South East Queensland. This decision is defended on the following grounds:
1. The sample is rich in information
2. It is accessible
3. The sample represents a segment important to the economy
As the purpose of the research is primarily to gain a deeper understanding of BPR and faced with the limitations of finance and time, the sample was purposive.
The primary hypothesis is: BPR has been unsuccessful because it is
poorly understood and has been confused with other techniques, such as TQM, which delivers incremental improvements, or simple down sizing.
The secondary hypothesis is: BPR is most likely to succeed in a stable and mature competitive environment, where, whilst competition may be intense, the competitive rules are well established and understood by the players.
In general, the first hypothesis was supported by the research findings, the second hypothisis could not be substantiated and requires further research using a much wider sample frame and modified instrument. Preliminary findings, and anecdotal evidence suggest that the second hypothisis will be supported. The paper not only offers reasons why BPR is loosing credibility, but also indicates the necessary prerequisites for successful
implementation.

Full textAbstract:
Spectral analysis of stationary processes has played an essential role in the development of Time Series. Nonstationary processes are less well understood however, although their consideration seems more realistic for many important applications. A summary of existing theory for stationary processes as well as a survey of the various classes of nonstationary processes that admit spectra will introduce this thesis. By combining and extending the ideas from the Wiener approach and the Khintchine-Kolmogorov-Cramer approach to stationary time series, a spectral representation and a mean ergodic theorem will be obtained under very mild conditions for a large class of nonstationary time series - the class of asymptotically stationary processes. Following these methods, a spectral representation for the class of asymptotically stationary random fields will be derived. The class of almost harmonizable random fields will be shown to be contained in the class of asymptotically stationary random fields. As an example of asymptotically stationary random fields, we consider the class of periodically correlated random fields. We give an upper bound for the covariance function of this class. A simulation is carried out to evaluate the accuracy of this approximation for the random field generated from a nonstationary random step function first defined by Wiener (1930). This result is useful in characterizing and distinguishing periodic textures.
A spectral representation is derived for a class of random fields which are bounded in mean square almost surely. A characterization of the corresponding spectral measure in the representation is obtained based on Beurling's duality theorem and generalized Fourier transforms. A representation for the covariance function is also defined for this large class which contains the class of asymptotically stationary random fields.

The transformation of Fe2+ to Fe3+ ions in ferrous sulphate-agarose-xylenol orange (FAX) gel due to irradiation results in a change of absorbance in the FAX gel, which can then be used for the dosimetry of the x-ray beam. The project's aim was to investigate the performance of a laser based system that determines the dose distribution of an x-ray field by measuring the change in absorbance of the FAX gel due to irradiation.
Initially a one-dimensional laser scanning system was constructed to perform calibration tests on the FAX gel. Calibration curves were obtained at different x-ray energies (200 kVp, 300 kVp, 6 MV, 10 MV) for the FAX gel and were approximated by a second order polynomial. The difference in the curve equation coefficients for the four dose curves was approximately 2% and hence indicating that the response of the FAX gel was not energy dependent. From a linear approximation of the calibration curve a G value of 57.8 ± 3.1 was calculated for a dose range of 0-10 Gy.
The reproducibility of the FAX gel was investigated through preparation and irradiation of a number of gel samples from a single batch. The standard deviations of absorbance measurements for both irradiated and unirradiated FAX gel samples were 1.2% and 1.1% respectively. These errors compare favourably with the standard deviation of 0.5-1 % in the conventional dosimeter (ion chamber) readings. The source of uncertainties in the FAX gel measurements is considered to be due to the continual thermal oxidation of ferrous ions in the FAX gel. Storage lifetime of the unirradiated FAX gel was investigated under a number of different storage enviroments. After 500 hours, the absorbance of the FAX gel stored under refrigeration increased by 25% whereas the absorbance of the FAX gel stored at room temperature and exposed to fluorescence light increased by 80%. The increase in the absorbance of the FAX gels led to a decrease in the dynamic range of the FAX gel response.
A scanning system was constructed to perform two-dimensional scans of a collimated x-ray field, and physical and dynamic wedged fields. For all three fields, the relative dose obtained by the laser based system was found to be within 3% of data acquired using the current standard measurement device (ion chamber). An advantage of the laser based system over the ion chamber was shorter irradiation times were required for data acquisition. These findings demonstrate the potential use of FAX gel phantoms for the acquisition of two-dimensional dose distributions.
An alternative scanning method for the FAX gels based on a video camera imaging system was also investigated. This system acquired a twodimensional dose distribution in a few minutes whereas the laser based system required up to 2 hours. To obtain any quantitative information using the video camera imaging system further investigations involving calibration of the system are required.
