Abstract:

Approved for public release, distribution unlimited Measuring the effectiveness of information systems (IS) is an issue that has generated debate and research among academics and practitioners. This thesis consolidates the numerous and various approaches to measuring IS effectiveness into six general schools of thought: user satisfaction, system usage, performance/usefulness, productivity, value analysis and cost-benefit analysis. It then presents a model for examining the various linkages that exist among the IS effectiveness measues. These linkages include: user satisfaction and system usage, system usage and performance, performance and productivity, and productivity and cost justification. This research provides a user a summary of the IS effectiveness literature of the past two decades and a consolidated reference for measuring the effectiveness of information systems.

Abstract:

This study focused on measuring the importance and contribution of information obtained from the library, particularly electronic information services (EIS), to success in solving clinical problems in hospitals. Three research questions with three main hypotheses were advanced and tested on clinicians in 44 hospitals in Hong Kong. The findings were tested against the framework from Wilson's (1996) existing general information behaviour model, from which a new extended model for clinicians was built. Measures of EIS were then derived from the new model. The research was broadly divided into a series of five studies in two stages: nominal group, quantitative survey, and interviews in the first stage, and randomized controlled study as well as the analyses of statistical data and computer transaction logs in the second stage. The key results in Stage I led to the studies in Stage 11. The randomized controlled study in Stage 11 attempted to reduce the barriers identified in the information environment, with a view to test the results of an educational intervention, and to confirm that the hypotheses were true given reduced barriers and the presence of enabling conditions. The effects of the interventions in this experimental study were validated and verified by statistical data and transaction logs. Corroborative evidence from the two-stage studies showed that the three main inter-connected hypotheses were supported: success in problem-solving is related to the information sources used; user satisfaction is related to success in problem-solving; and EIS use is an indicator of user satisfaction. EIS use is determined by a number of factors: the preference for EIS, the use of the library, the skills and knowledge in searching, the profession of the user and the characteristics of the work environment. Educational intervention was found to improve success in problem-solving, the attitudes, skills and knowledge in searching, the satisfaction with and use of EIS, and is an important enabling condition. The research rejected part of the first hypothesis posed that success in problem-solving is related to clinical question posed and suggests that further research is needed in this area. The study supported the extension of the general model to clinical information needs and behaviours and found new relationships. The study found an additional determinant of EIS satisfaction, the satisfaction with the information obtained. EIS satisfaction would not be changed by educational intervention alone if the information obtained was not satisfactory. On the other hand, education can improve EIS satisfaction regardless of whether the problem has been solved. Of critical importance is the time factor in determining the use (or non-use) of EIS. There is new evidence that the awareness of the user of an answer in literature is a determining factor for active searching. Borrowing the concept of opportunity cost from economic theory, the researcher relates it with the differing levels of self-efficacy and postulates a model for planning EIS and related library services. From the new extended model of information behaviour, sixteen main measures or indicators were tested on a proposed framework in developing performance measures to diagnose information behaviours and predict EIS use, satisfaction and success in problem-solving. In measuring EIS, the researcher suggested the holistic approach in assessing traditional (non-electronic) library and information services as part of information behaviours of clinicians. The study pointed to the imbalance between self-efficacy and the actual skills and knowledge of users in their searching mentality and activities and the implication for library practice. Qualitative aspects that require further research on measurement were suggested. The study has important ramifications for theory and practice for the information professional. The new extended model of information behaviour for clinicians establishes deterministic relationships that help explain why an information search is pursued actively, continuously, or not at all. Measures that have been derived from these relationships can help diagnose and predict information behaviours. The study highlights the flexibility and utility of the general model of information behaviour. Also, this is the first time that such a methodological approach has been adopted to derive EIS measures. The application of the randomized controlled study methodology in information science was proven to be feasible and yielded definitive results. The researcher proposes that further development of information behaviour model should incorporate the element of knowledge generation process in an organization.

Abstract:

The objective of this study was to develop valid methodologies for addressing several limitations of the current Advanced Traveler Information Systems (ATIS) evaluation tools. This study was focused mainly on three enhancements. First, the queue propagation algorithm of the selected tool (DYNASMART-P) was modified to more realistically model traffic congestion. The author proposed the addition of transfer flow capacity and backward gated flow constraints for more accurately calculating transfer flow rate. Second, the study modeled the natural diversion behaviors of drivers who do not receive traveler information. Lastly, statistical models of user responses to traveler information were developed using binary and multinomial logit methods to understand and model the relationship between driversâ socio-economic characteristics and their responses to traveler information. Among these three enhancements, the first two (improved queue propagation and natural diversion behavior algorithms) were implemented in the enhanced model. The user behavior models, however, were not implemented because their predictive power was not acceptable due to limitations in the data set. The enhanced model was applied to two case studies: 1) verifying the capabilities of the model under a recurring bottleneck scenario on I-40 corridor in the Triangle region of North Carolina, and 2) demonstrating the capability of the enhanced model to measure the effectiveness of U-Transportation (similar to the Vehicle Infrastructure Integration [VII] program in the USA) which has been under development in Korea. The first case study results showed that the improved queue propagation algorithm simulated the bottleneck queue much closer to the real data than the original model. The simulation results also indicated that the actual diversion rate under recurring congestion in the study network was very low. The results of the second case study demonstrated that the enhanced model can evaluate the network impact of new advanced technology in flooding situations and can evaluate the effect of market penetration of the communication technology.

Abstract:

The purpose of the research is to examine the attitudes of IS executives to the current and future importance of some of the approaches to measuring IS efficiency and IS effectiveness in large Australian organisations. The study identified the nature of IS effectiveness approaches along the lines of whether they are business-oriented, IS internal/operational, financial, quantitative or qualitative measures. It also examined whether the structure of the IS management and industry sector had an effect on attitudes towards these measures.

Abstract:

Thesis (Ph. D.)--Massachusetts Institute of Technology, Engineering Systems Division, 2011. Cataloged from PDF version of thesis. Includes bibliographical references (p. 125-133). Health information exchange (HIE) - the electronic exchange of health information among healthcare institutions - has been projected to hold enormous promise as an antidote to the fragmented healthcare delivery system in the United States. After decades of mostly failed attempts, we still do not know how to make HIE work. This thesis is the beginning of a systematic understanding of HIE, focusing on the clinical users and the context in which the users and the technology interact. It uses a systems approach to understand HIE from the perspectives of the core stakeholders including healthcare providers, patients, health IT vendor companies, public policy, and the HIE organizations that supply data exchange services. The core contributions of the thesis are contained in four studies. Values of healthcare providers as stakeholders in HIE In a stud y of three communities, healthcare provider organizations were found to expect regional HIE organizations to bring them benefits from the ability to measure care quality. However, one relatively larger community placed greater value on the strategic interests of its individual provider institutions, whereas two smaller communities valued the interests of the communities as a whole. Factors that affect clinicians' usage of HIE. In a study of clinician-users of an operational HIE, usage factors were categorized as motivators and moderators. Motivators for individual clinicians' usage of HIE included improving care quality and time savings. Moderators were numerous and included gaps in data, workflow complexity and usability issues. Several policy options and implications are discussed including: requiring HIE organizations to report metrics of HIE contributions and accesses; certifying HIE vendor companies to provide standardized usage metrics; and creating incentives for clinicians as well as HIE organizations and regional health IT extension centers to meet HIE usage targets. Analysis of opportunities to use HIE. In one community, 51% of visits involved "care transitions" among individual providers, and 36-41% involved care transitions between medical groups. The percentage of a provider's visits which involved care transitions varied considerably by clinical specialty and even within specialties. Within primary care, individual clinicians' "transition percentages" varied from 32% to 95%. This study discusses how policies designed to foster HIE usage should take this variation into account. Analysis of mergers and provider recruitment on HIE value. In a simulation study of patient visit patterns in 10 communities, the results suggest that even after substantial consolidation of medical groups, an HIE would still have considerable value as measured by the number of opportunities for data exchange. However, in each community a small number of medical groups were key: if absent from a community HIE, these groups would reduce the value by 50%. Conversely, if they were the only groups participating, the HIE's value would only achieve 10-20% of its value with all groups participating. The results of these studies suggest that HIE will be needed even in the event of the expected large-scale consolidation of healthcare providers. However, efforts will be needed to recruit medical groups to join HIE organizations, to improve HIE technology, and to train clinicians to integrate HIE into their workflows. by Robert S. Rudin.

Abstract:

Currently, there are a number of ways ISE calibrations, each of which depends on several factors: the amount and nature of the sample, frequency analysis, metrological characteristics and electrode-active properties of the material of the electrodes themselves. However, these calibration methods have limitations when used in the flow-injection analysis method (FIA).

Abstract:

Approved for public release; distribution is unlimited As a result of the unregulated rise of superfluous interoffice e-mail, employees currently must wade through inboxes glutted with needless information to find the tidbits of valuable data actually needed to perform their jobs. This problem, also known as e-mail overload, creates unnecessary stress, reduces workplace productivity and fundamentally threatens the information superiority of both private and government enterprises. Organizations that try to combat e-mail overload by employing e-mail policies, filters and personal e-mail management techniques often find that these initiatives miss the mark or do very little to reduce the dissemination of superfluous e-mail. This thesis aims to utilize systems thinking to provide a more complete evaluation of the pitfalls associated with the abovementioned performance improvement initiatives, and also to demonstrate the central (but often overlooked) role that balancing feedback and metrics play in systems that have underlying goal-oriented behaviors. This thesis finally proposes an Information Glut Ratio (IGR) that can potentially provide an organization with a basic, tailorable process for measuring, stabilizing and regulating the amount of superfluous information that gluts e-mail inboxes.

Abstract:

This is a case study of a federal bureaucracy and its Information Resource Management (IRM) organization. The Bonneville Power Administration (BPA), a federal power marketing agency and part of the Department of Energy, significantly impacts the western United States. BPA is responsible for developing electric power resources, transmission of electric resources. power conservation programs, and fish and wildlife programs. The focus of the study is the perception of the quality of information supplied to management, assuming that better information makes better decisions. The study uses a pre-experimental research design to evaluate the satisfaction executive and middle management with information they use to make decisions. The study uses both questionnaire and interview methodologies to examine management opinions before the establishment of IRM and two years after the establishment of IRM. Literature on bureaucracy indicates that decision making has limits and processes. Channels of communication, both formal and subformal are used by decision makers to gather information to fill information gaps. The gaps exist because formal channels of information do not supply sufficient information. Consequently, decision makers constantly search for information. There is a great deal of literature addressing IRM and other similar organizations. The technical and operational sides of information management are occasionally conflicting but, adequately addressed. Information assessment and evaluation are approached inadequately.

Abstract:

Thesis (PhD (Electrical and Electronic Engineering))--University of Stellenbosch, 2010. ENGLISH ABSTRACT: We propose a new methodology, based on proper scoring rules, for the evaluation of the goodness of pattern recognizers with probabilistic outputs. The recognizers of interest take an input, known to belong to one of a discrete set of classes, and output a calibrated likelihood for each class. This is a generalization of the traditional use of proper scoring rules to evaluate the goodness of probability distributions. A recognizer with outputs in well-calibrated probability distribution form can be applied to make cost-effective Bayes decisions over a range of applications, having di fferent cost functions. A recognizer with likelihood output can additionally be employed for a wide range of prior distributions for the to-be-recognized classes. We use automatic speaker recognition and automatic spoken language recognition as prototypes of this type of pattern recognizer. The traditional evaluation methods in these fields, as represented by the series of NIST Speaker and Language Recognition Evaluations, evaluate hard decisions made by the recognizers. This makes these recognizers cost-and-prior-dependent. The proposed methodology generalizes that of the NIST evaluations, allowing for the evaluation of recognizers which are intended to be usefully applied over a wide range of applications, having variable priors and costs. The proposal includes a family of evaluation criteria, where each member of the family is formed by a proper scoring rule. We emphasize two members of this family: (i) A non-strict scoring rule, directly representing error-rate at a given prior. (ii) The strict logarithmic scoring rule which represents information content, or which equivalently represents summarized error-rate, or expected cost, over a wide range of applications. We further show how to form a family of secondary evaluation criteria, which by contrasting with the primary criteria, form an analysis of the goodness of calibration of the recognizers likelihoods. Finally, we show how to use the logarithmic scoring rule as an objective function for the discriminative training of fusion and calibration of speaker and language recognizers.

Abstract:

The doctoral research project is titled ‘An Exploration of the Relationship of Organisational Culture and Enterprise System Success and sought to address the research gap identified in the literature between organisational culture literature and Information System success literature. This is a research project which is funded by the Australian Research Council in conjunction with industry. The industry sponsors for this research were SAP AG, SAP USA and SAP ANZ. The research project adopted a multi-method research design, grounded in practice, in order to surface any reported relationship between Enterprise Systems Success (ESS) and Organisational Culture (OC). A critical part of the study was to identify who could report on this relationship. Partners in implementation include internal change managers, internal consultants, vendor consultants and implementation partner consultants. Representatives from each of these constituents were interviewed, covering a range of industry sectors and Enterprise Systems vendor organisations. The first phase of the research was to qualitatively assess the perception of these participants on the role of culture to Enterprise Systems Success. This phase used open, axial and selective coding of the responses obtained in a semi-structured interview. The next phase of the research was to gather quantitative measures of Organisational Culture and Enterprise Systems Success. The Organisational Culture Assessment Inventory (OCAI) of Cameron and Quinn was selected to gather quantitative data on Organisational Culture. The Enterprise Systems Success instrument of Gable, Sedera and Chan was selected to measure the perception of ESS because of its proven reliability and validity. Each of these data sets were then analysed to determine if an association existed between the cultures of organisations that achieved most success with the Enterprise System as opposed to the culture types reported of organisations that achieved the least success with the ES. These findings then assisted in the development of a model of interaction between OC and ESS. Finally, the relationship of OC to ESS was explored in a rich case study of one large firm, to determine if the consultant’s reported relationships could be identified in the subcultures of the organisation. The key findings of this study were: 1. There was a relationship reported between culture type and success types. The findings a-e below represent findings using the culture definitions from Cameron & Quinn’s culture instrument: a. clan cultures which emphasised the behaviours of development of others were related to reports of ESS b. hierarchical cultures which emphasised the behaviours of control and coordination were related to reports of ESS c. hierarchical cultures which were poor in the execution of control and coordination were related to reports of the least success with ES d. market cultures which emphasised (internal) competitiveness were strongly related to reports of least success with ES e. literature attributes of continuous improvement (CI), flexibility (F) and innovation (I), which are often described as antecedents to innovation success and are found in the culture type of adhocracy, were reported as strongly related to success of ES, but the culture type of adhocracy was not reported as being present in the quantitative data describing consultant experiences with enterprises which had implemented ES. 2. that the literature supported theoretical reasons for the above findings 3. that these patterns of association were found in the case study. The research supports the proposition that there is a relationship between Organisational Culture type and ESS. Certain culture types practice behaviours that correspond to reported necessary behaviours for innovation success and ESS, whilst other culture types practice behaviours that correspond to behaviours for failure of innovation and of ES failure. A model of and explanation for this relationship was proposed as a result of the findings. Future research is now required to empirically test this model.

Abstract:

Because of the expansion in health information technology and the continued migration toward digital patient records as a foundation for the delivery of healthcare services, healthcare organizations face significant challenges in their efforts to determine how well they are protecting electronic health information from unauthorized disclosure. The disclosure of one's personal medical information to unauthorized parties or individuals can have broad-reaching and long-term impacts to both healthcare providers and consumers. Although several classes and types of methodologies exist for measuring information security in general, a number of overarching issues have been identified which prevent their adaptation to the problem of measuring the confidentiality (the protection from unauthorized disclosure) of electronic information in complex organizational systems. In this study, a new approach for measuring the confidentiality of electronic information in healthcare-related organizations is developed. By leveraging systemic principles and concepts, an information security system (ISS) for assuring the confidentiality of electronic information in healthcare organizations is synthesized. The ISS is defined as a complex system composed of the Health Insurance Portability and Accountability Act (HIPAA) Security Rule information security safeguards and the people, processes, and technologies that contribute to these safeguards. The confidentiality of the ISS – a desired emergent property defined in terms of the systemic interactions which are present – represents the measure of protection from the unauthorized disclosure of electronic information. An information security model (ISM) that leverages the structure and parametric modeling capabilities of the Systems Modeling Language (SysML) was developed for specifying an ISS in addition to the contained systemic interactions which are present. Through the use of a parametric solver capability, the complex system of equations which quantify the contained interactions was executed for the purpose of generating a measure of confidentiality using a set of user-provided input values – a process referred to as ISM instantiation.

Full text

Abstract:

Information systems (IS) research frequently uses survey data to measure the interplay between technological systems and human beings. Researchers have developed sophisticated procedures to build and validate multi-item scales that measure latent constructs. The vast majority of IS studies uses classical test theory (CTT), but this approach suffers from three major theoretical shortcomings: (1) it assumes a linear relationship between the latent variable and observed scores, which rarely represents the empirical reality of behavioral constructs; (2) the true score can either not be estimated directly or only by making assumptions that are difficult to be met; and (3) parameters such as reliability, discrimination, location, or factor loadings depend on the sample being used. To address these issues, we present item response theory (IRT) as a collection of viable alternatives for measuring continuous latent variables by means of categorical indicators (i.e., measurement variables). IRT offers several advantages: (1) it assumes nonlinear relationships; (2) it allows more appropriate estimation of the true score; (3) it can estimate item parameters independently of the sample being used; (4) it allows the researcher to select items that are in accordance with a desired model; and (5) it applies and generalizes concepts such as reliability and internal consistency, and thus allows researchers to derive more information about the measurement process. We use a CTT approach as well as Rasch models (a special class of IRT models) to demonstrate how a scale for measuring hedonic aspects of websites is developed under both approaches. The results illustrate how IRT can be successfully applied in IS research and provide better scale results than CTT. We conclude by explaining the most appropriate circumstances for applying IRT, as well as the limitations of IRT.

Abstract:

This thesis develops a measurement model and method that allows information system professionals to establish measures of information system size that are accurate and may be established early in the system development life cycle. It reports the results of an empirical investigation into the aspects of requirements and design metrics which lead to the production of source code. The theoretical foundations used to investigate this topic originate in systems theory, models of information systems and organizational theories of structure and complexity. Models of system development are reviewed as they play a key role in our notions of activities to perform during development. By drawing on existing estimating models from software engineering and other sources of practitioner literature, a model to predict development effort was synthesized. Three distinct constructs emerged: 1) system requirements, which drive effort; 2) personnel experience, which can mitigate effort; and 3) technology, which can also mitigate effort. System requirements was chosen to further define and operationalize, since they are the principal source of development complexity and hence system size. An Entity-Relationship and Event approach was taken to establish an early measure of System Requirements size. A theoretical framework of data and process complexity was developed which may be used to initially size a development project based on the information available at the requirements specification and design phases. It is argued that this new approach is more general than existing sizing techniques; namely, Function Points and Lines of Code. This new sizing approach is tested against 26 simple transaction based processing systems developed in FOCUS. An automated Code Analyser was developed to reverse engineer these systems back to their design measures. The personnel and technology variables were held constant for this initial test. For the thesis, only retrospective measurement occurred but it is expected that longitudinal measurement will eventually be possible. Two primary research contributions are seen emanating from this study. First is the development and application of theory to the problem of information system sizing. Second is a method for data collection and analysis which will help the software development industry move towards the goal of system development measurement and evaluation. This will improve planning for, and management of, information systems development. Business, Sauder School of Graduate

Abstract:

Corpus-based methods are now dominant in Natural Language Processing (NLP). Creating big corpora is no longer difficult and the technology to analyze them is growing faster, more robust and more accurate. However, when an NLP application performs well on one corpus, it is unclear whether this level of performance would be maintained on others. To make progress on these questions, we need methods for comparing corpora. This thesis investigates comparison methods based on the notions of corpus homogeneity and similarity.

Abstract:

IntroductionIn our Bachelor’s thesis we wrote about the advantages, risks, strategies and methods useful when working with Green IT. But there still were difficulties delimiting the field of Green IT. This was mostly because of the lack of previous research, unestablished definitions of the term Green IT as well as nonexistent methods to measure the accomplished work. Furthermore the recent changes in the environment, with escalating pressure from stakeholders with environmental concerns and increased costs of investments and maintenance, have forced IT-companies to measure the effects of IT and its financial impact.Purpose The purpose of our research study is to further clarify the field of Green IT by establishing a definition and constructing a KPI-setting.MethodWe first established a definition of the term Green IT by gathering available definitions and analysing them. The analysis resulted in two definitions; one for Green IT (a technology product used to support information gathering, processing, distribution and use, and which is or contributes to environmental sustainability) and one for a Green IT Company (manages the process of producing technology used to support information gathering, processing, distribution and use, and which is or contributes to environmental sustainability). These definitions made us realise that there are users and manufacturers of Green IT, with distinctive perspectives and needs when measuring it. According to our definitions we found respondents to interview in order to construct two KPI-settings instead of one.ConclusionsThe first KPI-setting constructed focuses on producers of Green IT and their production activities along with the financial impact. The second KPI-setting focuses on users of Green IT and looks at the usage of Green IT, and also includes financial indicators to measure financial impact.

Abstract:

Advances in Information and Communication Technology (ICT) and the drastic growth of the Internet over the past decade have considerably changed the environment for end users of computer systems. Therefore, it is important to review how user satisfaction is measured with information systems, especially in a web-based environment. User satisfaction has become one of the most important measures of the success or effectiveness of information systems; however, there is a need of better understanding of its structure and dimensionality in the web environment. The objective of this research was to develop and validate an instrument for measuring user satisfaction in a web-based environment. In this research, three commercial websites were taken as representatives of Web-Based Information Systems (WBIS) for e-services. This study involved testing the validity and reliability of the end-user satisfaction over a set of heuristics, based on responses from users of three e-service websites. This thesis explores not only the role of user satisfaction but also the role of aesthetics and other factors, which play a significant role in service oriented websites. In the past, satisfaction was thought to originate from the effectiveness and efficiency of a product and less from its aesthetic qualities. This theory is beginning to change as numerous studies have indicated the importance of visual aesthetics in web design. In service interfaces, aesthetics (the perceived visual appeal and appropriateness of an object) has shown to correlate positively with many aspects of usability and emotional satisfaction.

Abstract:

As the number of electronic services provided by governments to their citizens has increased, so has the need for understanding whether citizens are satisfied with these services. A literature review indicated that, in the United States alone, several government entities, including federal, state, and local governments, have invested large amounts of resources to develop or introduce electronic government (e-Government) to their citizens. However, very little attention has been paid to developing a standard scale for measuring the intended benefits or for justifying the invested resources. The focus of this study was the development and validation of a scale for measuring e-government user satisfaction (EGUS) to close this gap. Through review of extant literature, a 9-dimensional structure with 86 items was extracted to measure EGUS. Then, a preliminary content validity study was conducted with a 10-member panel of experts, who examined the items to ensure the psychometric properties of the scale were theoretically and empirically sound. This process resulted in elimination of 14 items. The main study was conducted based on the remaining 72 items. Data was collected from 225 e-government users via Web-based survey to assess their experience with online engagement. The items were further subjected to iterative test of dimensionality, construct validity, and internal consistency reliability. The end result was a 9-dimensional scale structure with 67 items. The results of the study indicated that all nine dimensions of EGUS (information content, ease of use, accessibility, timeliness, efficiency, security, privacy, interactivity, and format) were significant in influencing e-government user satisfaction. Thus, this research model has resulted in the basis for development of a new instrument to measure user satisfaction within e-government domain and the groundwork for expanding research on user satisfaction studies within the e-government paradigm. Within the body of knowledge, it has revealed insight into the importance of end user satisfaction in electronic government research. The instrument could be used in various fields of study. E-government practitioners and citizens could also use it for better understanding of the benefits of e-government services over traditional government services. Government personnel could use it to justify investments.

Abstract:

Most of the process measurement studies are related with time and cost based models. Although quality is the other conventional aspect, there are no widely used models for measuring the process quality in the literature. In order to provide complementary information about the quality, a process quality measurement model has been chosen to be developed and the studies about process characteristics have been searched in the scope of the thesis. Moreover, by utilizing the similarities between process and software, the studies in software quality have been investigated. In the light of the researches, a model is built on the basis of ISO/IEC 9126 Software Product Quality Model. Some of the quality attributes are redefined in the model according to the process characteristics. In addition, new attributes unique only to the process are developed. A case study is performed and its results discussed from different perspectives of applicability, understandability and suitability.

Abstract:

Nowadays the competition between cities is something very common, especially between cities of different countries. But this competition it can be observed even between cities of the same country or between districts of the same city. Based on this phenomenon municipalities try to change and become more sustainable (socially and environmentally), implement more green spaces in their urban core, create vibrant local environments and launch campaigns in order to create liveable districts, improve their local economy and survive this growing competition. In other words, cities want to become more attractive.In Sweden cities are also part of this global trend and since they are growing economically they try to create an urban environment that is desirable for its citizens. In Stockholm’s Översiktsplan there are different main goals, such as “The growing city (växande stad)” which is analyzed as “An attractive big city” or “Good public spaces (God offentlig miljö)” which is analyzed as “Mixed use urban space”, “Inviting public space”, “Living local centers” leading to the question how do these correlate and how do they affect each other.The reason of this research is to understand what is an attractive area in a city and find out a way to measure attractiveness by using spatial or non-spatial factors who play a major role on how a city is perceived. It is known based on existing research and literature, that many different factors are involved for a place to be considered as attractive, such as the distance from the means of transport, the distance to public amenities, house affordability, vibrant lifestyle, the distance from market places, social equality, the distance from the city center, the proximity to nature and many others, but there is no index that uses all these factors and calculates an attractiveness score.So this research aims in the creation of an attractiveness index, by formulating a lot of different indicators (social, geographic, economic, etc) based on the Översiktsplan goals and the calculation of attractiveness of different areas in Stockholm. The areas are SoFo District in Södermalm, Skarpnäck suburb in the south and Tensta suburb in the north. The main goal of this research is to improve the urban quality in Stockholm by identifying problematic areas, in order to increase the awareness about urban quality and the way to accomplish this research is the use of Multi-Criteria Evaluation in collaboration with Geographic Information Systems.Based on all the above the research question in this thesis will be: How city’s block attractiveness is measured with the use of Multi-Criteria Evaluation and the implementation of Geographic Information Systems?

Abstract:

Master of Regional and Community Planning Department of Landscape Architecture/Regional and Community Planning Jason Brody Recent research has focused on assessing equity with regards to location of public services and the population served. Instead of equality, equity involves providing services in proportion to need, rather than equal access for everyone. This study uses three commonly identified measures of accessibility (minimum distance, travel cost, and gravity potential) to assess how equitable higher-need residential populations of Kansas City, MO are served by neighborhood parks. Using Census 2000, socio-economic block group data, areas with high population concentrations of African-American and Hispanic populations, as well as areas of high density and low income are characterized as having the most need. However, correlations of higher-need populations with the accessibility measures reveal patterns of equity within the Kansas City. MO study area. Results indicated that while most of the high need population was adequately and equitably served by neighborhood parks, there were still block groups that did not have access to this type of public resource. This research follows methods proposed in previous studies that utilize the spatial mapping and analysis capabilities of ArcGIS and promote the use of these tools for city planners and future park development and decisions.

Abstract:

Much of the confusion about the effectiveness of information security programs concerns not only how to measure, but also what to measure — an issue of equivocality. Thus, to lower uncertainty for improved decision-making, it is first essential to reduce equivocality by defining, expanding, and clarifying risk factors so that metrics, the "necessary measures," can be unambiguously applied. We formulate a system that (1) allows threats to be accurately measured and tracked, (2) enables the impacts and costs of successful threats to be determined, and (3) aids in evaluating the effectiveness and return on investment of countermeasures. We then examine the quality of controls implemented to mitigate cyber risk and study how effectively they reduce the likelihood of security incidents. Improved control quality was shown to reduce the likelihood of security incidents, yet the results indicate that investing in maximum quality is not necessarily the most efficient use of resources. The next manuscript expands the discussion of cyber risk management beyond single organizations by surveying perceptions and experiences of risk factors related to 3rd parties. To validate and these findings, we undertake in an in-depth investigation of nearly 1000 real-world data breaches occurring over a ten-year period. It provides a robust data model and rich database required by a decision support system for cyber risk in the extended enterprise. To our knowledge, it is the most comprehensive field study ever conducted on the subject. Finally, we incorporate these insights, data, and factors into a simulation model that enables us study the transfer of cyber risk across different supply chain configurations and draw important managerial implications.

Abstract:

Thesis (MA)--University of Stellenbosch, 2004. ENGLISH ABSTRACT: Recently there has been growing interest in evaluating the performance and outcomes of spatial planning policies worldwide. In response to this a research was carried out to evaluate and monitor the effectiveness of spatial planning policies in the Cape Metropolitan Area (CMA). The Planning Indicators Model (PIM), which consists of a set of twenty-six indicators, was applied to monitor and measure the extent to which the Metropolitan Spatial Development Framework (MSDF) has affected land use and physical development in the CMA. To achieve the aim of the study, the research was divided into three phases. The first phase involved a literature review, the second phase involved interviews with planning officials and lastly, the collection of different thematic datasets required to run the Planning Indicators Model. The data sets were used to monitor and display spatiotemporal variations in conformance and performance indices in the form of maps. These maps were used to identify areas where strengths can be protected and where weaknesses need to be corrected. From a set of 26 indicators used for this study only two indicators monitored conformances (Growth of informal housing townships) over the period 1993 – 1998; the others simply indicated the present conditions. This means that the rest of the indicators did not show trends. However, the data are presented in this report as a useful baseline for future conformance and performance monitoring exercises. The study also revealed that for the past twelve years the MSDF has been the subject of extensive debate within the local authorities. Also several indicators seem to overlap and need to be clearly defined, thus it is recommended that some of these indicators should be combined to avoid duplication and confusion. Generally, the PIM can assist in making the impact of spatial planning greater in the CMA. AFRIKAANSE OPSOMMING: Onlangs is daar wêreldwyd groeiende belangstelling in die prestasies en uitkomstes van ruimtelike beplannings- beleide. In reaksie daarop is hierdie navorsing gedoen om die doeltreffendheid van die ruimtelike beplannings- beleide van die Kaapse Metropolitaanse Gebied (KMG) te evalueer en te monitor. Die Beplannings Aanwysers Model (BAM) wat bestaan uit ‘n stel van ses-en- twintig aanwysers, is aangewend om te meet tot hoeverre die Metropolitaanse Ruimtelike Ontwikkelings Raamwerk grondgebruik en fisiese ontwikkeling in die Kaapse Metropolitaanse Gebied beïnvloed het. Om die doelwit van hierdie studie te verwesenlik, is die navorsing gedoen in drie fases. Die eerste fase bestaan uit ‘n oorsig van die literatuur en die tweede fase uit onderhoude met amptenare verantwoordelik vir beplanning. Die laaste fase beslaan die versameling van die verskillende tematiese stelle data wat benodig word vir die Beplannings Aanwysers Model. Die stelle data is gebruik om die ruimtelike- en tydsvariasies in die konformering- en prestasie indekse te monitor en ten toon te stel in die vorm van kaarte. Hierdie kaarte is gebruik om die gebiede te identifiseer waar sterkpunte behoue moet bly en waar swakpunte reggestel moet word. Uit die stel van 26 aanwysers wat gebruik is vir hierdie studie, het net twee aanwysers konformering (Die groei van dorpsgebiede met informele behuising) gedurende die periode 1993 – 1998 gemonitor; die ander het eenvoudig die huidige toestand aangetoon. Dit beteken dat die ander aanwysers nie tendense aangetoon het nie. Die data word egter in hierdie verslag weergee as ‘n nuttige basis vir die toekomstige monitor van konformering en prestasie. Die studie toon ook aan dat daar gedurende die afgelope twaalf jaar baie deur plaaslike owerhede gedebatteer is oor die Metropolitaanse Ruimtelike Ontwikkelings Raamwerk. Ook oorvleuel sommige van die aanwysers en moet hulle meer duidelik omskryf word. Dus word daar aanbeveel dat sommige van die aanwysers gekombineer moet word om duplikasie en verwarring te voorkom. Oor die algemeen kan die Beplanning Aanwysers Model help om die impak van ruimtelike beplanning op die Kaapse Metropolitaanse Gebied te bevorder.

Abstract:

In today's connected society, where it is common to have several connected devices per capita, it is more important than ever that the data you need is omnipresent, i.e. its available when you need it, no matter where you are. We identify one key technology and platform that could be the future—peer-to-peer communication and the Web. Unfortunately, guaranteeing consistency and availability between users in a peer-to-peer network, where network partitions are bound to happen, can be a challenging problem to solve. To solve these problems, we turned to a promising category of data types called CRDTs—Conflict Free Replicated Data Types. By following the scientific tradition of reproduction, we build upon previous research of a CRDT framework, and adjust it work in a peer-to-peer Web environment, i.e. it runs on a Web browser. CRDTs makes use of meta-data to ensure consistency, and it is imperative to remove this meta-data once it no longer has any use—if not, memory usage grows unboundedly making the CRDT impractical for real-world use. There are different garbage collection techniques that can be applied to remove this meta-data. To investigate whether the CRDT framework and the different garbage collection techniques are suitable for the Web, we try to reproduce previous findings by running our implementation through a series of benchmarks. We test whether our implementation works correctly on the Web, as well as comparing the memory efficiency between different garbage collection techniques. In doing this, we also proved the correctness of one of these techniques. The results from our experiments showed that the CRDT framework was well-adjusted to the Web environment and worked correctly. However, while we could observe similar behaviour between different garbage collection techniques as previous research, we achieved lower relative memory savings than expected. An additional insight was that for long-running systems that often reset its shared state, it might be more efficient to not apply any garbage collection technique at all. There is still much work to be done to allow for omnipresent data on the Web, but we believe that this research contains two main takeaways. The first is that the general CRDT framework is well-suited for the Web and that it in practice might be more efficient to choose different garbage collection techniques, depending on your use-case. The second take-away is that by reproducing previous research, we can still advance the current state of the field and generate novel knowledge—indeed, by combining previous ideas in a novel environment, we are now one step closer to a future with omnipresent data. I dagens samhälle är vi mer uppkopplade än någonsin. Tack vare det faktum att vi nu ofta har fler än en uppkopplad enhet per person, så är det viktigare än någonsin att ens data är tillgänglig på alla ens enheter–oavsett vart en befinner sig. Två tekniker som kan möjliggöra denna ``allnärvaro'' av data är Webben, alltså kod som körs på en Webbläsare, tillsammans med peer-to-peer-kommunikation; men att säkerställa att distribuerad data både är tillgänglig och likadan för alla enheter är svårt, speciellt när enhetens internetanslutning kan brytas när som helst. Conflict-free replicated data-types (CRDT:er) är en lovande klass av datatyper som löser just dessa typer av problem i distribuerade system; genom att använda sig av meta-data, så kan CRDT:er fortsätta fungera trots att internetanslutningen brutits. Dessutom är de garanterade att konvergera till samma sluttillstånd när anslutningen upprättas igen. Däremot lider CRDT:er av ett speciellt problem–denna meta-data tar upp mycket minne trots att den inte har någon användning efter en stund. För att göra datatypen mer minneseffektiv så kan meta-datan rensas bort i en process som kallas för skräpsamling. Vår idé var därför att reproducera tidigare forskning om ett ramverk för CRDT:er och försöka anpassa denna till att fungera på Webben. Vi reproducerar dessutom olika metoder för skräpsamling för att undersöka om de, för det första fungerar på Webben, och för det andra är lika effektiv i denna nya miljö som den tidigare forskningen pekar på. Resultaten från våra experiment visade att CRDT-ramverket och dess olika skräpsamlingsmetoder kunde anpassas till att fungera på Webben. Däremot så noterade vi något högre relativ minnesanvändning än vad vi har förväntat oss, trots att beteendet i stort var detsamma som den tidigare forskningen. En ytterligare upptäckt vad att i vissa specifika fall så kan det vara mer effektivt att inte applicera någon skräpsamling alls. Trots att det är mycket arbete kvar för att använder CRDT:er peer-to-peer på Webben för att möjliggöra ``allnärvarande'' data, så innehåller denna uppsats två huvudsakliga punkter. För det första så fungerar det att anpassa CRDT-ramverket och dess olika skräpsamlingsmetoder till Webben, men ibland är det faktiskt bättre att inte applicera någon skräpsamling alls. För det andra så visas vikten av att reproducera tidigare forskning–inte bara visar uppsatsen att tidigare CRDT-forskning kan appliceras i andra miljöer, dessutom kan ny kunskap hämtas ur en sådan reproducering.

Full text

Abstract:

Enterprise social network software platforms (ESNs) are increasingly being deployed in firms across almost every industry as a means of fostering employee collaboration. Although benefits in increased productivity, innovation, and employee engagement are highly touted, there is a high failure rate of these deployments. This often occurs because (1) there is a misapplied focus on technology adoption rather than adoption of the employee behaviors that are ultimately required to obtain those benefits, and (2) it is unclear what those behaviors are and how to measure them. “Working Out Loud” is one possible framework for understanding and measuring the behaviors necessary to fulfill the promise that ESN vendors advertise. It is loosely described as doing work in a way that makes it visible to others, and is often associated with the use of social business tools. As these tools proliferate within organizations, the Working Out Loud concept is becoming increasingly popular as an organizational and individual goal and mantra among social software vendors, their customers, and leading pundits and consultants in this space. Many benefits have been associated with Working Out Loud; however the concept is still somewhat amorphous. No attempts have been made to quantify it and little research has been done on whether the benefits attributed to it really exist. The common industry definition of Working Out Loud identifies two separate behaviors: narrating one’s work in the form of blog posts, status updates, etc. (typically individual behavior), and performing work in a transparent and observable way through the use of an enterprise social platform (typically group or team behavior). This research hypothesizes that these two behaviors do exist and are related but distinct, and thus scales can be developed to measure each. A survey was given to employees of Lexmark International, Inc. (the author’s employer). Exploratory and confirmatory factor analyses performed on the data confirmed the hypothesis and resulted in scales for individual and group Working Out Loud that are designed to be minimallyintrusive so as to enable both researchers and practitioners to track an organization’s Working Out Loud behavior on an ongoing basis.

Abstract:

Målet med undersökningen har varit att undersöka möjligheten att ta fram en kostnadseffektiv lösning för att mäta flöden i slutna rörsystem. Anledningen till att kontaktlösa metoder valts för arbetet är dess egen-skaper att kunna installeras utan att göra ingrepp i ledningarna eller på något sätt påverka det flödande mediet i dessa. Utrustning skall inhand-las och testas i fält. I underökningen ingår det även att ta fram en lämplig metod för att trådlöst överföra insamlat mätdata till valfri IT-miljö och där kunna presentera mätdata på ett översiktligt sätt i ett övervaknings-system samt använda mätdatat till olika statistiska beräkningar. Det hu-vudsakliga applikationsområdet som undersöks är läckageindikering i dricksvattenledningsnät. Anledningen till detta är att många kommuner inte har råd att investera i dyr mätutrustning för övervakning och för dem kan det vara intressant med ett billigt system som är relativt enkelt att installera och implementera i deras befintliga övervakningssystem. Re-sultat av en enkätundersökning som gjorts i samband med undersök-ningen har visat att intresset är stort hos kommunerna, men den visar även att övervakning av vattenledningsnäten med vissa traditionella me-toder kommer att bli svårare i framtiden i och med den stigande andelen plaströr i ledningsnäten. Fälttester av inköpt mätutrustning visar att den skulle kunna implementeras och fungera som flödesövervakning i led-ningsnät. Även fast dess mätnoggrannhet var under det förväntade så vi-sade utrustningen på god linjäritet. The aim of the survey has been to investigate the possibilities of using a cost-effective solution for measuring flows in closed pipes. Non-intrusive measuring methods are chosen because it’s able to install them without interfering the flow in- or alter- the pipe in any way. Equipment will be purchased and field tested during the time of the survey. The survey also includes investigating suitable methods for wirelessly transmitting col-lected data to an IT-environment, and using measurement data for sur-veillance purposes and various statistical calculations. The main applica-tion area investigated is leakage indication in drinking water pipeline net-works, the reason being that many municipalities can’t afford to invest in expensive measuring equipment and they may be interested in an inex-pensive system that is relatively easy to install and implement in their existing monitoring system. The results of a poll conducted in connection with the survey have shown that there is considerable interest among the municipalities, but it also shows that monitoring of the water supply net-works with traditional methods may become more difficult in the future, the main reason for this seems to be the increasing amount of plastic pipe-lines in the pipeline networks. Field tests of the purchased equipment show that it may be suitable to implement as flow measuring device with the purpose of leakage monitoring, even though its measurement accu-racy was below expected it still shows good linearity.

Abstract:

Den fundamentala principen för tillverkning av papper är inte en särskilt komplicerad sådan. Men för att pappret skall erhålla specifika egenskaper blir processen alltmer komplicerad. Bland annat tillsätts olika typer av kemikalier och processen övervakas ständigt av olika system. Ett av dessa system mäter pH-halten i pappersmassan. Mätsystemet är dock utsatt för frekventa mätfel vilket medför en felaktig dosering av den koldioxid som används för att sänka pH-värdet. Detta kan slutligen ha negativ påverkan på papprets egenskaper. Syftet bakom arbetet är att mätsystemet ska bidra till en jämn reglering av pH och därigenom garantera jämn papperskvalitet. För detta arbete har en frågeställning och ett antal mål och delmål etablerats. De övergripande målen omfattar att etablera en statistisk modell över mätfel och beräkna eventuella ekonomiska besparingar. För att uppfylla mål och besvara frågeställningen måste en grunduppfattning byggas uppför berörda delar av tillverkningsprocessen, pH-värdets påverkan i processen, pH-sensorns mätprincip, mätsystemets utformning och rutiner som berör mätsystemet. Med denna grund undersöks uppkomsten av mätfel för de sex mätpunkterna. Detta utförs med två tillvägagångssätt: Sammanställning av lagrade historiska data och sammanställningar avprovtagningar utförda under kontrollerade förhållanden. De aspekter som undersöks är magnitud, frekvens och hur dessa förhåller sig till olika processrelaterade värden. En kalkyl för kostnader berörande mätsystemet upprättas även. Denna omfattar aktuella kostnader för koldioxid och underhåll. I resultatet presenteras en statistisk modell över mätfel, uppdelat på historiska och i närtid. Den historiska modellen visar, för samtliga behandlade positioner, en medelavvikelse på <0,3 pH-enheter. Den min- och maximala avvikelsen kan däremot uppgå till >0,8 pH-enheter. Modellen för närtid visar på kraftiga avvikelser för fyra av de sex behandlade systempositionerna, som relaterar både till papperskvalitet och ytvikt. Denna statistiska modell används sedan för att beräkna möjliga besparingar. Här påvisades att viss besparing fanns, både för koldioxid och för underhållskostnader. Slutsatsen för detta arbete är att ett mätfel existerar för majoriteten av de behandlade positionerna. Det har även kunnat påvisas ett samband med de undersökta processrelaterade aspekterna, men resultatet kan inte garanteras fullständigt. Med detta kunde även en möjlig besparing av koldioxid uppskattas vid bättre mätnoggrannhet. Besparingen uppgick till c:a 200 tkr, vilket i jämförelse med företagets omsättning endast utgör 0,075‰ av denna. The fundamental principle for manufacturing paper is not a complicated one. However, for the paper to acquire specific properties, the process becomes increasingly complicated.Among other things, different chemicals are added, and the process is continuouslymonitored by various systems. One of these systems measures the pH-level of the pulp. This system is however constantly affected by measuring errors, which in turn leads to the incorrect dosage of the carbon dioxide used to lower the pH-level. This could in turn have a negative impact on the properties of the final paper. The underlaying purpose of this project is for the measuring system to ensure an even regulation of pH and therethrough guarantee an even paper quality. For this project, several question at issue, goals and subgoals have been established. The general goals cover establishing a statistical model for the error and estimate possible economical savings. To fulfil the goals and answer the questions at issue, firstly a basic understanding must be established for: concerned parts of the manufacturing process, the effect pH-level has on the process, the measuring principle of the pH-sensor, the design of the measuring systemand the routines concerning the measuring system. With this basis, the occurrence of measuring error is examined for the six measuring points. This is accomplished with two methods: The compilation of historical data and the compilation of manual measurementsexecuted under controlled conditions. The aspects examined are magnitude, frequency and the relation to process related values. Finally, a calculation for costs regarding the measuring system was established. This includes current carbon dioxide and maintenance costs. The result presents a statistical model for the measuring error, divided into historical and near time. The historical model shows that for all the addressed positions, a mean deviation occurred <0.3 pH-units. However, the minimum and maximum deviation could reach >0.8 pH-units. The model for near time shows significant deviations for four out of the six covered positions, which in turn shows relations to both paper quality and surface weight. With this statistical model possible savings were calculated. This in turn showed the possibility of savings for both carbon dioxide and maintenance. The conclusion for this project is the existence of a measuring error. Also, a connection between this and the process related aspects could be established. Although, the result cannot be completely guarantied. With this, possible savings through better accuracy could be estimated. Though, these were only in the size of 0.075‰ of the company’s total revenue.

На основании установленных зависимостей разработан новый неразрушающий метод определения ударной вязкости материала, позволяющий расширить количество измеряемых информативных параметров, характеризующих фактическое техническое состояние металлоконструкций долговременной эксплуатации. Определены пути реализации предложенного метода путем разработки экспериментального образца информационно измерительной системы для определения ударной вязкости материала трубопровода. Dissertation is devoted to the problem of improvement of technical diagnostics method of oil and gas pipelines. It is investigated and substantiated the possibility and feasibility of impact strength parameter to determine the actual technical state of pipelines and assess its remaining life. A lot of experimental studies of Ukrainian and foreign scientists showed a significant change of metal’s impact strength for long term operation. It is determined that thus change is characterized by two intervals - at the first interval the impact strength varies little (10-15 years of operation), the second - is more significant declines. The transition between the first and second intervals in most cases depends on the material, operation conditions and therefore is an individual for a particular pipeline. A descriptive physical model of the effect of metal’s impact strength changes on the pipeline’s actual technical state is developed. This model is based on several factors, namely the reduction of impact strength due to aging, fracture toughness reduction and increasing the ductile-to-brittle transition temperature to a range of operating temperatures. Causes of metal aging lie in structural changes, related primarily to the dynamics of dislocation structure, decomposition cementite component, the redistribution of carbon and nitrogen atoms, microstrains accumulation, increasing of internal stresses in the metal structure. The aging process conditions depend on the structural parameters of material, operating temperature and stress level in the pipe wall. The main problem of this metal is increasing its sensitivity to stress concentrators and defects and to the formation of the metal destruction locations. Based on experimental data and graphical dependencies and given the main provisions of the model, under which, the actual technical state of the pipeline is determined by the number of factors, the function for describing the remaining life of pipeline is proposed. This function represents the general principle of technical state evaluation and remaining life assessment considering the metal’s impact strength change. The developed model allows proposing a new grapho-analytical method for calculating the remaining life of pipelines with a defect. The principle of the new method is to calculate stress, in which the pipe defect will failure. The index of impact strength change over the operation time is inputted in the famous equation NG-18. By the new grapho-analytical method it is possible to determine the time at which defect failure stress (determined using equation NG-18 considering impact strength reduction over operation time) will reach the actual stress of pipe wall. Validation of the method was carried out at crude data from the pipeline with lower impact strength and corrosion. In order to develop a new method for evaluation the actual technical state of gas pipelines considering impact strength reduction the approach based on the management of several informative parameters is developed. The relationships with mechanical characteristics are established for these informative parameters. The complex of experimental investigations was carried out to establish the existence and form of the relationship between the measurable parameters (hardness, coercive force and electromagnetic oscillations frequency of inductive transducer) and the actual values of impact strength of the pipeline material. In order to establish an optimal set of parameters for control and approximation of impact strength as a function of measurable parameters, which helped get its analytical and graphic form, the modem methods of data processing (artificial neural network) was improved and used. On the basis of the dependencies a new non-destructive method for determining the impact strength of the material was developed. This method expands the number of informative measurable parameters that characterize the actual state of long-term operation metalware. To increase the information content of the developed non-destructive method and its applicability for pipe steels the additional tests for impact strength determining were carried out. Samples temperature was around 0 degrees Celsius. Samples were with the V-notch. There was an investigation for the choice of optimal frequency of inductive transducer electromagnetic oscillations. For this purpose the experimental unit was developed. It allows measuring the frequency of electromagnetic oscillations (informative parameter I) with high accuracy. Optimal frequency of electromagnetic oscillations (25 kHz) was chosen as a result of correlation analysis between impact strength and informative parameter values measured at different frequencies. The development of experimental sample of information and measuring system is one of the ways for work results implementation. Work results were approved within the contract of Ivano-Frankivsk National Technical University of Oil and Gas with Main Pipeline Department "Donbastransgas" under the conditions of Novopskov Local Gas Transmission Facility. In particular, it was carried out successful industrial tests of information measuring system. The decreasing of pipeline material impact strength was discovered by non-destructive method. The remaining life of the pipeline considering impact strength change was calculated based on the obtained data. It is recommended to include developed grapho-analytical method in the procedure of safe operation life extension that is laid out in the draft international standard ISO 13623 Petroleum and natural gas industries - Pipeline transportation systems. Recommendations are sent to the ISO Technical Committee 67 “Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries: In addition, thesis materials were used by the development of Standard of Ukraine 60.3-30019801-067:2009 "Main gas pipelines.

Abstract:

Although the physical characteristics of surfing breaks are well described in the literature, there is little specific research on surfing and coastal management. Such research is required because coastal engineering has had significant impacts to surfing breaks, both positive and negative. Strategic planning and environmental impact assessment methods, a central tenet of integrated coastal zone management (ICZM), are recommended by this thesis to maximise surfing amenities. The research reported here identifies key oceanographic considerations required for ICZM around surfing breaks including: surfing wave parameters; surfing break components; relationship between surfer skill, surfing manoeuvre type and wave parameters; wind effects on waves; currents; geomorphic surfing break categorisation; beach-state and morphology; and offshore wave transformations. Key coastal activities that can have impacts to surfing breaks are identified. Environmental data types to consider during coastal studies around surfing breaks are presented and geographic information systems (GIS) are used to manage and interpret such information. To monitor surfing breaks, a shallow water multibeam echo sounding system was utilised and a RTK GPS water level correction and hydrographic GIS methodology developed. Including surfing in coastal management requires coastal engineering solutions that incorporate surfing. As an example, the efficacy of the artificial surfing reef (ASR) at Mount Maunganui, New Zealand, was evaluated. GIS, multibeam echo soundings, oceanographic measurements, photography, and wave modelling were all applied to monitor sea floor morphology around the reef. Results showed that the beach-state has more cellular circulation since the reef was installed, and a groin effect on the offshore bar was caused by the structure within the monitoring period, trapping sediment updrift and eroding sediment downdrift. No identifiable shoreline salient was observed. Landward of the reef, a scour hole ~3 times the surface area of the reef has formed. The current literature on ASRs has primarily focused on reef shape and its role in creating surfing waves. However, this study suggests that impacts to the offshore bar, beach-state, scour hole and surf zone hydrodynamics should all be included in future surfing reef designs. More real world reef studies, including ongoing monitoring of existing surfing reefs are required to validate theoretical concepts in the published literature.

Comparison analysis is developed using different research methods, quantitative approach for the external system and mixed methods approach for the internal system depending on the different amount of users. Measured by evaluation of actual users of the systems, research results show mostly positive conclusions along with unsupported results of service quality and system quality. Negative and insignificant results are further explained by interviews with internal system users. The external system is resulted having more positive and significant effects compared to the internal system.

Abstract:

碩士 中華大學 企業管理學系碩士班 99 In recent years, hotel firms have employed information system as a solution to improve organisational performance. However, the factors that lead to the success of hotel information system remain unclear. While many researchers have investigated the validity of DeLone and McLean (D&M) IS success model, very limited studies have been conducted to assess the success of information system in the context of hotels. It is therefore important to measure the success of hotel information systems, especially from the perspective of employees. Therefre, the purpose of this study is to examine and validate the D&M 's IS success model in the context of hotels from the perspective of employees. The research model in this study consisted of six constructs: information quality, system quality, service quality, systems use, user satisfaction, and net benefits. The questionnaire items were majorly based on DeLone and McLean's article and several related literature. Data collected from 303 respondents in the international hotels in Taiwan were tested against the research model using the structural equation modeling approach. Apart from the path from information quality to systems use, the hypothesized relationships among the six success variables were significantly supported by the data. The findings provide several important implications for hospitality research and practice.

A research report submitted to the Faculty of Commerce, University of Witwatersrand, Johannesburg, in partial fulfilment of the requirements of the degree of Master of Commerce. Information Systems (IS) project management is fundamental to organlzations who are involved in the development of information systems, yet IS projects can fail for any number of reasons, and insome cases can result in consi derable financial losses for the organisations that undertake them. One pattern of failure is .hat the IS project takes on a life of its own, continuing to absorb valuable resources without reaching its cbjective. A significant number of these projects will ultimately fail, potentially weakening an organisation's competitive position while siphoning off resources that could be spent developing and implementing successful systems. Earned value performance measurement (EVPM) is a management technique that relates resource planning to schedules and to technical performance requirements. It is formed on a platform of fundamental project management, but with earned value performance measurement, with its focus being the continuous measurement of actual achievement against a detailed performance plan, thus providing a basis for problem identification, corrective actions, and management replanning, whilst providing the information necessary to be able to predict the final costs and fmal schedule forecasts for the project. The purpose of this study is to highlight the earned value performance measurement system, and propose it as an alternative approach that can be used for controlling the IS software development effort.

Abstract:

碩士 銘傳大學 資訊管理研究所 88 Since proposed by Parasuraman, Zeithaml, and Berry in 1985, SERVQUAL is a good and widely used means for measuring service quality. However, it still exists a lot of disputes in the IS domain. An alternative instrument, namely SERVPERF, proposed by Cronin and Taylor in 1992 was capable to compare with SERVQUAL on measuring service quality. The main purpose of this study is to compare reliability, construct validity, criterion-related validity, dimensionality, and predictive superiority of the revised SERVQUAL with the revised SERVPERF on measuring information systems service quality. The study conducted an empirical survey to examine three different industries─banking, manufacturing, and non-manufacturing (service). The empirical result suggests that the revised SERVPERF instrument outperforms the revised SERVQUAL instrument in reliability, construct validity, criterion-related validity, dimensionality, and predictive superiority on measuring IS service quality. Moreover, this study also investigates whether the results of overall service quality, overall satisfaction toward IS service, and further IS service intentions will have statistical significance in four demographic variables (sex, age, level of education, and year of work experience). The result indicates that overall service quality, overall satisfaction toward IS service, and further IS service intentions do not have statistical significance in four demographic variables.

The survey questionnaire was distributed to students during the revision week of the course and a total of 61 valid responses were gathered from them. The linear regression analysis using statistical package for the social sciences was performed to analyse the data. Findings The results indicated the significant relationships for all six hypotheses. The model explains variance of 43.2 per cent in learning performance, which indicates that independent constructs contribute significantly on the research model's performance. Research limitations/implications First, the sample only provides the students' views about the use of clickers in the classroom setting. Second, the sample size for the gathered data is small. Third, the variance explained by the research model is reasonably moderate and hence can be improved further.

The patients can get first aid from the EMT(emergency medical technician) in the ambulance. However, the effectively first-aid time for intensive patients are very short, and not all the cases can be solved by EMTs. The patients only can get careful examination and cure after reaching the hospital. Worst of all, more detail information cannot be offered to the hospital for a well-prepared prework as the patients are on the way to the hospital. The patients will get more sick! If EMTs can transfer the physiology information of the patients to the hospital on the way to the hospital, the doctors in the hospital will get more information about the patients on the ambulance and make a decision immediately for the symptom, and all the prework will be prepared by the people in the hospital. As soon as the patients reach the hospital, they will be cured right away! No more wasting time!! In order to achieve the purpose, this research propose and to build a system that can capture the patient physiology information and then the information about the patients will be delivered to the hospital right away. The doctors on the side of the hospital can utilize the information to make an initial diagnosis, therefore relative equipments and medical workers will be well-prepared. After the patients reaching the hospital, they will get further examination and more critical care. The system really save lots of time and keep the golden time for first-aiding.

碩士 國立高雄應用科技大學 金融資訊研究所 95 ABSTRACT As the financial products are becoming more and more complicated due to continuous innovation, the financial markets are more volatile than ever. It is more and more difficult for corporate managers to deal with the market risks caused by the changes of stock prices and exchange rates of their portfolio. Since the G30 and BIS recommend or regulate the Value-at-Risk (VaR) as a way to measure market risks, VaR has become an important tool on market risks management. In order to calculate VaR efficiently and accurately, the application of computer software will be indispensable. The software of MATLAB and EXCEL VBA are employed in this research to build information systems of calculating VaR in both Monte Carlo simulation approach and historical simulation approach. It takes three companies stock prices (China Steel, Hon Hai Precision Industry and Cathay Financial Holdings) and three foreign exchange rates (TWD/USD, JPY/USD and ERU/USD) as empirical data. The purpose of this empirical research is not only to verify the accuracy of the information systems, but also to compare and analyze the results from the VaR of 1-day and 10-day estimation horizon with 95% and 99% confidence level under 1-year and 5-year historical data observation periods. The main conclusions of this research are as follows: (1) Monte Carlo simulation approach: when the numbers of simulation are over 10,000 times, the VaR will converge. The VaR calculated by the both systems are much closed, and pass back test and likelihood ratio test thoroughly. (2) Historical simulation approach: the VaR calculated by the both systems are the same. The systems can calculate the VaR under different decay factors given and improve the efficiency and accuracy of calculation.
