Harder kernels in barley are thought to be a factor affecting the modification of the endosperm during malting by restricting water and enzyme movement within the endosperm. The traditional method used in the malting industry to determine barley endosperm vitreousness is by visual assessment. Since this method is subjective, laborious and requires training, an alternative method is needed. Similarly, the causes and factors influencing kernel hardness are uncertain. The prime objectives of this study were: to identify an appropriate method to quantify kernel hardness; investigate the relationship between kernel hardness and endosperm composition; and to investigate the relationship between barley variety and environmental influences on endosperm composition in relation to the kernel hardness of malting barley.

A desire to more fully understand the impact of altered states of spiritual health on the general health of patients has been a focus of recent research activity. Studies have explored the meaning of spirituality held by patients and nurses, the spiritual needs of patients, and methods of providing spiritual care in nursing. However, few studies have investigated nurses’ own spiritual health and the significance this may have on the provision of holistic nursing care. The aim of this study, therefore, was to inform nursing regarding the spiritual health of nurses and the influence that nurses’ own spiritual health has on their ability to provide holistic nursing care to their patients. The study was conducted in two phases using both quantitative and qualitative methodologies. Phase one consisted of a survey of Division 1 nurses currently employed in the Grampians region of Victoria to describe key dimensions of their spiritual health. This survey provided biographical data and, through the use of the “Shalom Measure of Spiritual Health”, discovered the ideal of spiritual health held by nurses as well as the nurses’ perception of patient needs pertaining to the achievement of spiritual health. Phase two utilised Naturalistic Inquiry to further explore the meaning of spirituality and spiritual health held by nurses, and the methods of achieving these for nurses and patients. The findings revealed that although nurses perceive the spiritual dimension of patient care to be important, they feel ill-equipped to provide this aspect of care. In addition, the major support for nurses, who themselves experience spiritual distress whilst at work, comes from colleagues. Further, prevailing health care systems in place do not always lend themselves to holistic approaches to care. This study identifies the need for nurse education to redress the clearly inadequate preparation nurses are given for this aspect of their role. Health care policy-makers and administrators also have a responsibility to consider all dimensions of care when designing and implementing health care guidelines and systems.

The indigenous grass Lachnagrostis filiformis (Fairy grass) has colonised extensive areas of dry lakebeds in western Victoria, Australia during the current (1997-) drought. Large numbers of the plants' detached seed heads disperse in the wind and lodge against housing, fences, railway lines and other obstacles ... In this study, late season application of Glyphosate based herbicide, slashing, seed broadcasting of Atriplex australasica and Puccinellia perlaxa, grazing and burning were examined ... The results highlight how weed management aimed at achieving short-term goals, without controlling the ecological processes that promote weeds establishment and persistence, can be counter productive in the long-term.

This thesis examines, via a feminist theoretical framework, the systems in existence that permit the ongoing exploitation of the environment; and the appropriateness of ceramics as a medium to reinvigorate dormant insights. I argue that the organic nuances expressed through clay; the earthy, phenomenological and historic ritual connotations of clay; and the tactile textured surfaces and undulating form, allows ceramics to conjure responses within the viewer that reinvigorates a sense of embedment in the Earth.

In recent years large-scale global optimization (GO) problems have drawn considerable attention. These problems have many applications, in particular in data mining and biochemistry. Numerical methods for GO are often very time consuming and could not be applied for high-dimensional non-convex and / or non-smooth optimization problems. The thesis explores reasons why we need to develop and study new algorithms for solving large-scale GO problems .... The thesis presents several derivative-free hybrid methods for large scale GO problems. These methods do not guarantee the calculation of a global solution; however, results of numerical experiments presented in this thesis demonstrate that they, as a rule, calculate a solution which is a global one or close to it. Their applications to data mining problems and the protein folding problem are demonstrated.

"This dissertation illustrates an interdisciplinary sport science approach to further understand the interaction between physiology and performance in tennis. An integral theme throughout the experimental phases was the emphasis on obtaining information from actual competitive scenarios or settings that simulated a match environment. [...] This study extended the work of similar investigations through the multifaceted methods in which performance was quantified. Overall the thesis provides unique insight into the physiological demands of professional tournament tennis and the constraints these impose on performance. Furthermore, evidence was accrued to support some of the common preparatory and in-match behaviours used by players to enhance performance."

Text Classification is the task of mapping a document into one or more classes based on the presence or absence of words (or features) in the document. It is intensively being studied and different classification techniques and algorithms have been developed. This thesis focuses on classification of online documents that has become more critical with the development of World Wide Web. The WWW vastly increases the availability of on-line documents in digital format and has highlighted the need to classify them. From this background, we have noted the emergence of “automatic Web Classification”. These mainly concentrate on classifying HTML-like documents into classes or categories by not only using the methods that are inherited from the traditional Text Classification process, but also utilizing the extra information provided only by Web pages. Our work is based on the fact that, Web documents, contain not only ordinary features (words) but also extra information, such as meta-data and hyperlinks that can be used to advantage the classification process. The aim of this research is to study various ways of using the extra information, in particularly, hyperlink information provided by HTML-documents (Web pages). The merit of the approach, developed in this thesis, is its simplicity, compared with existing approaches. We present different approaches of using hyperlink information to improve the effectiveness of web classification. Unlike other work in this area, we will only use the mappings between linked documents and their own class or classes. In this case, we only need to add a few features called linked-class features into the datasets, and then apply classifiers on them for classification. In the numerical experiments we adopted two wellknown Text Classification algorithms, Support Vector Machines and BoosTexter. The results obtained show that classification accuracy can be improved by using mixtures of ordinary and linked-class features. Moreover, out-links usually work better than in-links in classification. We also analyse and discuss the reasons behind this improvement.

Description:
Rapid changes in the competitive environment and increasing customer demands drive the public and private sectors to innovate by continually investing millions of dollars in Information and Communication Technology (ICT) projects. Basically, organisations depend on ICT technology for every part of their business. Companies are not only challenged to apply new technologies to remain competitive, they also need to spread (diffuse), manage and implement technological innovation across extended organisational boundaries. Diffusion, management and implementation of ICT innovation involve a considerable amount of risk and potentially protracted delays of technological projects. As a consequence of high demand for ICT innovation, as well as the risk of failure, a wide range of organisations such as state agencies and banks now employ so-called change agents to diffuse, manage and implement innovation within technological projects. While a large number of academics and practitioners are concerned with change agents who alter organisational culture, structure and processes, relatively little research has been undertaken on the role of ICT change agents in the innovation process. Thus, this professional doctorate study aims to fill that gap by exploring ICT change agents’ project work experiences within state agencies and banks and fuse them with theory. The research is based on case study methodology, including 41 cases within 12 target organisations in Australia and Germany. As a former ICT change agent, the researcher of this Doctor of Business Administration (DBA) study applied mixed research methods, also incorporating her ICT project experiences by using an individual reflection model. From this investigation emerged that change agents’ roles are embedded in components (organisational structure, project stages) and processes (ICT diffusion, informal networks). These findings underpin the model of ICT change agents who perform the multiple linker roles of these components and processes in order to deliver set project outcomes. The model is designed to inform practice by providing guidance for advanced ICT change agents’ training in public and private sector settings.

The theory of abstract convexity generalizes ideas of convex analysis by using the notion of global supports and the global definition of subdifferential. In order to apply this theory to optimization, we need to extend subdifferential calculus and separation properties into the area of abstract convexity.

Several quantitative measures of spiritual well-being were developed with primary and secondary school students and teachers, and university education students, namely the Spiritual Health And Life-Orientation Measure, Feeling Good, Living Life, and the Quality Of Life Influences Survey. Spiritual dissonance was revealed by comparing respondents’ ‘ideals’ with ‘lived experiences’ in four domains of spiritual well-being. Teachers and university education students reported a decline in help being provided in schools to develop the relationships which foster school students’ spiritual well-being.
