Harmony is a major theme in Chinese culture. It is reflected in many forms, e.g. painting and garden design. However, calligraphy gives a straight forward insight into harmony in two dimensions. The main hypothesis was that the principles for building a harmonious calligraphic character could be converted from holistic to deductive and computable ones. These could then be applied to the design of harmonious screen interfaces, which would give visual pleasure. The first aim was to investigate and discover the quantifiable features of harmony in Chinese regular script calligraphy. Calligraphy has been associated in China with harmony and elegance for over 1500 years. There are features that are commonly accepted to establish harmony which can be quantified. However, the principles of Chinese calligraphy are embedded within Chinese culture. Direct translation does not convey the meaning. An extensive study was made of the literature on Chinese calligraphy and a practical exploration of characters was made. This resulted in a small number of principles which were needed to be satisfied for the character to appear harmonious. These were tested on several groups of participants. These principles were then converted into a mathematical form for Chinese regular script calligraphy, and for application to harmonious screen interface design. The mathematical forms were then tested on both Chinese regular script calligraphy and also on interface designs with groups of participants. Finally, an application for comparing harmony in Chinese calligraphic characters and interface designs was created. The “Harmony” application can be used to calculate how a Chinese calligraphic character or an interface design satisfies the principles of harmony and it can give an indication of how harmonious they are.

This research considers the ongoing challenge of semantics-based search from the perspective of how to exploit Semantic Web languages for search in the current Web environment. The purpose of the PhD was to use ontology-based query expansion (OQE) to improve search effectiveness by increasing search precision, i.e. retrieving relevant documents in the topmost ranked positions in a returned document list. Query experiments have required a novel search tool that can combine Semantic Web technologies in an otherwise traditional IR process using a Web document collection.

Title: The relevance and sustainability of Investors in People. Purpose: The purpose of this research project is to explore and challenge the relevance and sustainability of Investors in People (IIP) involvement and recognition within seven case studies. Research design: Seven in-depth case studies combining thirty-eight semi-structured interviews are used to gather the appropriate insights. Findings: In essence, it is the studied organizations themselves that generate what the Leitch Report describes as the “untapped and vast” potential of their employees, not IIP involvement or recognition. The data collected challenges the direct relationship frequently proposed between IIP recognition and increases in business performance. The sample organizations have delivered performance improvements and success independently of IIP consideration, raising serious questions over the relevance and sustainability of the standard. These insights are supported by the lack of knowledge and understanding of the standard within the workforce. In addition, other quality improvement tools and techniques and industry standards are found to have a significant detrimental influence on the standing of IIP. Other influences are also found to impact negatively on the standing. Thus, this research project questions what contribution IIP can make towards national competitiveness when the standard is so withdrawn from the business performance improvements integrated. Even as a badge or plaque of external recognition, the assumptions surrounding the perceptual value of IIP are questioned when the impact of the standard’s logo/ symbols is considered to be nominal. A theoretical framework and alternative definition for IIP are developed to represent the findings within the seven organizations studied. Research limitations: Research is needed beyond the case samples studied to further explore and generalize the rhetoric and realities concerning the insights developed. Practical implications: HR practitioners and managers need to exhibit caution before considering IIP involvement and recognition. Indeed, practitioners need to consider that the asserted benefits associated with IIP may not match their expectations and provide the impact they seek. Originality/value: This research project provides HR practitioners and managers with a valuable and timely alternative discourse and perspective when considering employee development towards IIP recognition and the possibility of improved business performance and customer/employee perceptual value. In addition, the theoretical exemplars developed from the data set provide visual representations that can be used as pragmatic comparisons to develop the field of IIP further.

Epidemiological data suggest a positive relationship between increased calcium intake and decreased fat and total body mass in healthy people (McCarron et al. 1984, Davies et al., 2000). An in-vitro model suggesting the role of cyclic Adenosine Monophosphate (cAMP) and phosphodiesterase 3B (PDE 3B) has been implicated in the relationship between calcium and lipolysis (Xue et al., 2001). The objective of the series of studies presented in this thesis was to investigate the ergogenicity of supplementary calcium in endurance exercise via studying its influence on substrate metabolism and body composition. Study 1 examined the effects of four weeks of calcium (citrate) supplementation (1000 mg elemental calcium/day) on 60 minutes of cycling at a submaximal intensity of 50%Wpeak. The results of this study indicated that calcium supplementation significantly improved body composition of the participants with a greater fat loss and increased lean mass observed in highly trained athletes as compared to the recreationally trained participants. In addition, four weeks of calcium supplementation also showed an enhanced trend of availability of fatty substrates in the plasma and consequently an increased trend towards higher fat oxidation during submaximal exercise. Study 2 and 3 thus examined the effects of calcium supplementation directly on performance during endurance events (25 and 10 mile cycling time trials (TT)) in highly trained athletes. Results from these studies indicate that following calcium supplementation there was a meaningful improvement in power output (PO) (~4%) during the 25TT and ~2.7% in 10TT with corresponding better completion times in both the time trials. This amounts to an increase in ~2-3% higher PO%peak and ~3-5% increase in power output at lactate threshold, with the higher percentages attributable to the 25TT and the lower end to the 10TT. This increase in PO was achieved without the corresponding increase in oxygen consumption, thus significantly improving the gross efficiency of the cyclists. In addition, four weeks of calcium supplementation once again exhibited the same trends in body composition as observed in study 1 of decreased fat mass and a concurrent increase in lean mass. The results from this set of investigation indicate that calcium plays a multifactorial role in performance enhancement of endurance events. This may have been achieved via a combination of influence on substrate metabolism and body composition. The impact of calcium on fatigue mechanisms and vascular tone may have also played a part in increasing PO and thus efficiency of the athletes. Thus the potential of calcium to enhance performance needs further investigation in studies with larger sample sizes and different training status of athletes.

The need for Shared Situational Awareness (SSA) in accomplishing joint missions by coalition militaries, law enforcement, the intelligence community, and the private sector creates a unique challenge to providing access control. In this thesis we investigate the capabilities and limitations of Role-Based Access Control (RBAC) to control the dissemination of SSA in a coalition environment. Our case study is that of controlling access to SSA in the Maritime Domain Awareness (MDA) environment. MDA exemplifies both rapid change in membership of coalitions and the roles of coalition participants. We explore the access policy and roles played by the participants in the MDA environment, in addition to the characteristics of those roles. We make use of feasible scenarios to provide us with a base for applying models to the situation. The models that are applied to the scenario provide the formal methods that prove that RBAC policies and derivatives such as Distributed Role Based Access Control (DRBAC), Coalition Based Access Control (CBAC) and Temporal Role Based Access Control (TRBAC) can be used in conjunction with the Information Broker (IB) concept to provide adequate access control policies.

M.Com. (Informatics) / This dissertation's objective is to supply a general, functional and business orientated discussion of the measurement of information system users' satisfaction. The result of this measurement acts as a measure of the data-processing function's success. It is however, not the purpose of this study to prescribe or develop a new standard method of measurement. This discussion also supplies a grounding for any further doctoral studies in this field. The dissertation's contents, highlights and exposition are being discussed in this synopsis. The motivation of this study lies first of all in the economical and strategic importance [2,3,44,20,17] of the data processing function for an organisation. Secondly, it lies in the importance of satisfied users, or clients, for the success of the data processing function. It is therefore important to always ensure the success of the data processing function, as well as to measure the subjective user satisfaction, accurately and effectively. This study is based on a previous study by Prof. JHP Eloff and DNJ Mostert [7,43], who created a general measurement process that determines the satisfaction of information system users; as well as various other research projects regarding the development and evaluating of these methods of measurement. The various, existing methods of measurement which were found in the literature, i.e: Pearson [6,33]; Baroudi [4,15]; Bailey [16]; Raymond [5] and Tan and Lo [36] , are being discussed in this dissertation. Due to the objective of this dissertation and the business orientated nature of this study, the statistical and critical evaluation of these methods are not being discussed. An attempt is however made to supply a broad view of the available methods of measurement, as well as the various contributions to the field of study by these research projects.

Design is a process of changing current situations into preferred ones, through conversations with design materials, and an understanding of the present practice of the designed artefact’s future users. Domain-relevant data, such as those generated by personal and autonomous computing systems, are an increasingly important design material presenting new ways to explore current practice. Examples of these data include that being generated by people using smartphones, health and fitness monitors, smart energy meters and social media; or that from official statistics made publicly available via Open Data initiatives. This thesis details research developing CoDesign With Data, a novel approach to collaborative early-stage design workshops in which working with domain-relevant data is the key distinguishing feature. During a CoDesign With Data workshop participants are given the tools and techniques to help them seek insight from data, gain an understanding of the context these data might come from, and to inspire creative design ideas. These tools and techniques build on an understanding of research into information visualization and applied creativity. The activities in which they are used build on the experiences reported from other approaches to creativity in collaborative requirements gathering and design workshops. The aim of this research is to support design innovation that results in new products or services appropriate to the contexts in which they will be used. To investigate the primary research question, and evaluate the tools and techniques being developed, two design experiments and three case studies were undertaken. In each study, examples of tools, in the form of workshop materials and information visualization interfaces, and techniques, in the form of workshop activities, are presented, and simple takeaways for design practice are offered. Finally, the knowledge and understanding gained during this research is presented as a series of guidelines and recommendations, and a description of the current state-of-the-art CoDesign With Data workshop.

A model of simulation with mixed-integer programming was created to simulate ordering, production planning, and supplying activities with and without supply information sharing in a three-level capacitated supply chain consisting of multiple suppliers, one manufacturer and multiple retailers. The simulation results indicate that supply information sharing can significantly reduce total cost and enhance service level of the whole supply chain and its members. It can also lessen order variance of downstream members in the supply chain. In addition, the impacts of supply information sharing on the supply chain performance are heavily influenced by demand patterns, capacity tightness, forecast accuracy, product substitution, and the availability of raw materials. / Fierce business competition forces enterprises to pay more attention to the coordination with their suppliers and customers. Information sharing is a prerequisite for coordinated supply chain operations. A wide range of literature emphasizes the importance of information sharing to supply chain performance. According to the direction of information flow between supply chain members, information sharing can be classified into two categories: demand-side information sharing and supply-side information sharing. Previous literature already made a wide variety of insightful explorations into demand-side information sharing in supply chain, such as demand, forecasting, inventory, and order information sharing. However, research efforts have rarely been made into supply-side information sharing. Therefore, this dissertation explores the impacts of supply-side information sharing. / Keywords. Information Sharing; Supply Chain; Simulation. / This dissertation contributes to extending the content and scope of supply chain information sharing research. Managerially speaking, the findings of this dissertation provide important reference for supply chain managers to implement supply information sharing in order to improve decision-making process, reduce uncertainties, and increase visibility in supply chain operations. / Zhou Qiang. / "June 2006." / Adviser: Tien-sheng Lee. / Source: Dissertation Abstracts International, Volume: 68-02, Section: A, page: 0648. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 170-176). / Electronic reproduction.
