Commercial recordings - CDs, LPs - are familiar objects. However, discussion about them has often attempted to conceal the fact that, as communicating objects, recordings pose special problems due to the fact that they unite text, image, and sound in a material commodity. This thesis examines the role of the visual in the production, circulation and use of recordings. The album cover is the primary category of study, with an emphasis on its functioning in relation to the recording as a sonic and material commodity. The label ECM, a German company which has been producing recordings since 1969, provides the main focus in this analysis. The basis of this investigation lies in the questioning of the assumptions and categories that have historically guided the activity of cover design and the discourse about it. Traditionally, recordings have been understandably seen primarily as sound-carriers; their visual aspects, even when celebrated, are most often relegated to a peripheral status, despite the fact that in certain contexts the importance of the visual can overwhelm that of sound. The usual hierarchical opposition between these elements is here questioned through an examination of both the marketing of recordings and their circulation and use. ECM provides a pertinent case through which such questions can be elaborated. Its visual marketing strategies can be characterised in terms of a desire for difference. ECM's attempt to set itself apart has resulted in a "look" which rejects many conventions. It has also resulted in a complex, conceptual group of visual strategies. In its particular use of landscape photography, blank space, and gestural markings, ECM constructs ideas of space which relate to the potential for performativity and creativity. Through the combination of these strategies, the label deemphasises creative personality of the musical performer and emphasises the space occupied by the looker/listener. In doing this, it also questions the traditional boundaries between music and the visual. ECM's covers cause these categories to become indistinct and allow new conceptions of the recording as a material commodity to emerge. One effect of this is a construction of the apprehender's subjectivity that fails to fit within the marketplace's traditional categories. The thesis considers how the visual has been implicated in more concrete processes such as the negotiation of taste and practices of consumption and use. The niche that ECM attempts to carve out for itself is considered in relation to the tension in the marketplace between the desire for distinction and the recording as a massproduced commodity. / Arts, Faculty of / Art History, Visual Art and Theory, Department of / Graduate

Why and how much should we invest in this information technology (IT)? The difficulty to formulate well-justified, convincing answers to those questions asked by corporate decision-makers has been identified as a major impediment to one rapid adoption of IT innovations by the business community. This study investigates the fundamental construct underlying these questions by performing a formal assessment of the business value of financial electronic data interchange (EDI) technology for corporate adopters in Canada. Three major Canadian financial institutions, seven cross-industry financial EDI user organizations (originators and receivers), several reference firms and more than fifty individuals actively participated in this study which follows a triangulation data collection approach. Within a cohesive financial EDI value measurement framework based on the theory of capital budgeting, a set of realistic and flexible models for measuring the business value of financial EDI was developed from a rigorous, item-by-item analysis of the data. Following a scenario-based approach, the data and models were used to estimate the magnitude of potential net benefits of financial EDI to corporate adopters. A formal evaluation of the expected and actual costs and benefits of financial EDI to participating user firms was conducted using the models. Several major conclusions were drawn from this in-depth study of financial EDI investments including, among others, the substantiated observation that from a payment process perspective, financial EDI is potentially more beneficial to corporate receivers than originators. Compared to non-financial EDI applications, potential economic gains from reduced payment cycles accrue primarily to the supplier community, rather than the initiators of financial EDI systems. Major contributions of this study include first, the development of a theory-based value measurement framework, and second, the presentation and application of a structured, iterative methodology for the evaluation of financial EDI investments. The proposed financial EDI cost/benefit models also offer a useful, practical set of tools to potential and actual user firms in evaluating the organizational value of future or current financial EDI programs. Finally, the study is also intended to assist Canadian financial institutions in their financial EDI diffusion effort. / Business, Sauder School of / Graduate

Therefore, this research aims to study in depth the importance and complexity of the document digital archives within the organizational environments. We seek, since the look of information science, a mechanism that may assist in the organization of documents described in companies from their own production, taking particular account of the contributions of international techniques that normalize the documentary process of entities, the scientific literature that deepens the search field and the laws of the governmental entities that establish legal rules and legal organization of documents. This mechanism that helps in the organization of business documents, is intended to provide a possible alternative for organizations that know the main advantages of the digital document within an appropriate document management system that improves the processes of informational flows and the methods of description, analysis and retrieval of documents. To carry out the purpose of this study, the methodology used was mainly theoretical analysis, descriptive, in which it stands out in terms of the archival document digital, the advancement of laws made by the Colombian Government and the effectiveness that these laws currently have to be applied in different organizations. The result of this work will contribute to other studies related with the current debate of archival document digital. / Mestre

Magister Curationis - MCur / The implementation, adoption and the use of EHR globally has been proven a challenge, despite the numerous advantages that have been noted with the use of an electronic health recording system to improve health care services. Among some of the challenges that have been reported is lack of knowledge and staff attitudes towards this new technology. It has also been noted that the success or failure of an EHR system is dependent on nurses’ or individual user acceptance, as they are pivotal in the healthcare team; therefore, their attitude towards an EHR system is crucial.

>Magister Scientiae - MSc / With the development of information and network technologies, Electronic Health Records (EHRs) management system has gained wide spread application in managing medical records. One of the major challenges of EHRs is the independent nature of medical institutions. This non-collaborative nature puts a significant barrier between patients, doctors, medical researchers and medical data. Moreover, unlike the unique and strong anti-tampering nature of traditional paper-based records, electronic health records stored in centralization database are vulnerable to risks from network attacks, forgery and tampering. In view of the data sharing difficulties and information security problems commonly found in existing EHRs, this dissertation designs and develops a credible Blockchain-based electronic health records (CB-EHRs) management system.

Falls are the second leading cause of accidental or unintentional injury deaths worldwide. Many factors contribute to an increased risk of falling, such as age, disease state, and medication use. The purpose of the current investigation was to compare an electronic medical record (EMR) fall risk calculator, the theoretical Timed Up and Go (T-TUG), which utilizes gender, age, BMI, and prescription and OTC drug counts as variables, to other established performance- and paper-based assessments of fall risk. The National Social Life, Health, and Aging Project (NSHAP) Database was used to develop the T-TUG. Data was analyzed from participants in Wave 1 of the Irish Longitudinal Study on Ageing (TILDA) to validate the T-TUG. Performance-based assessments included mean grip force for both dominant and nondominant hands, Timed Up and Go (TUG), and a paper-based assessment titled the Steadiness Index. The latter is a series of 3 questions assessing steadiness when walking, standing, or getting up from a chair. Those participants of the TILDA cohort passing the inclusion criteria were divided into those who reported a fall in the previous year (N=1159) and those reporting no falls (N=4746). Two group comparisons were analyzed by Mann-Whitney U Test (p<0.05) and a Receiver Operator Characteristics (ROC) curve analysis was used to detect separation of fall and non-fall groups. For the Mann-Whitney U test the fall and no fall groups were statistically different for the T-TUG (p<0.001), TUG (p<0.001), dominant and nondominant grip forces (p<0.001), and the steadiness index (p< 0.001). In the fall group, the grip forces were weaker, T-TUG and TUG time longer, and the steadiness index scores lower. For the grip force assessments and steadiness index, lower scores are more likely to be associated with a higher fall risk. In the T-TUG and TUG, longer times are more likely to be associated with a higher fall risk. In the ROC curve analyses, the T-TUG (0.567, p<0.001) demonstrated similar outcomes compared to dominant (AUC=547, p<0.09) and non-dominant (AUC=0.550, p<0.01) grip forces, and the TUG (AUC=0.558, p<0.001). The steadiness index ROC analysis was slightly better than the T-TUG (AUC=0.579, p<0.001). Sensitivity (52-58%) and specificity (50-57%) ranges were equivalent for all performance-based assessments, whereas for the Steadiness Index, the sensitivity (40%) was lower than the specificity (75%). The EMR fall-risk calculator (T-TUG) is a valid triage tool to estimate fall risk in older community dwellers. The EMR calculator has the potential for real-time assessment of patients using current data compared to other performance- and paper-based assessments, which would allow the healthcare team to spend more time with higher fall risk patients.

Learning representations of medical concepts from the Electronic Health Records (EHRs) has been shown effective for predictive analytics in healthcare. The learned representations are expected to preserve the semantic meanings of different medical concepts, which can be treated as features and thus benefit a variety of applications. Medical ontologies have also been explored to be integrated with the EHR data to further enhance the accuracy of various prediction tasks in healthcare. Most of the existing works assume that medical concepts under the same ontological category should share similar representations, which however does not always hold. In particular, the categorizations in the categorical medical ontologies were established with various factors being considered. Medical concepts even under the same ontological category may not follow similar occurrence patterns in the EHR data, leading to contradicting objectives for the representation learning. In addition, these existing works merely utilize the categorical ontologies. Actually, it has been noticed that ontologies containing multiple types of relations are also available. However, studies rarely make use of the diverse types of medical ontologies. In this thesis research, we propose three novel representation learning models for integrating the EHR data and medical ontologies for predictive analytics. To improve the interpretability and alleviate the conflicting objective issue between the EHR data and medical ontologies, we propose techniques to learn medical concepts embeddings with multiple ontological representations. To reduce the reliance on labeled data, we treat the co-occurrence statistics of clinical events as additional training signals, which help us learn good representations even with few labeled data. To leverage the various domain knowledge, we also consider multiple medical ontologies (CCS, ATC and SNOMED-CT) and propose corresponding attention mechanisms so as to take the best advantage of the medical ontologies with better interpretability. Our proposed models can achieve the final medical concept representations which align better with the EHR data. We conduct extensive experiments, and our empirical results prove the effectiveness of the proposed methods.

Masters of Science / With the development of information and network technologies, Electronic Health Records (EHRs) management system has gained wide spread application in managing medical records. One of the major challenges of EHRs is the independent nature of medical institutions. This non-collaborative nature puts a significant barrier between patients, doctors, medical researchers and medical data. Moreover, unlike the unique and strong anti-tampering nature of traditional paper-based records, electronic health records stored in centralization database are vulnerable to risks from network attacks, forgery and tampering. In view of the data sharing difficulties and information security problems commonly found in existing EHRs, this dissertation designs and develops a credible Blockchain-based electronic health records (CB-EHRs) management system. To improve security, the proposed system combines digital signature (using MD5 and RSA) with Role-Based Access Control (RBAC). The advantages of these are strong anti-tampering, high stability, high security, low cost, and easy implementation. To test the efficacy of the system, implementation was done using Java web programming technology. Tests were carried out to determine the efficiency of the Delegated Byzantine Fault Tolerance (dBFT) consensus algorithm, functionality of the RBAC mechanism and the various system modules. Results obtained show that the system can manage and share EHRs safely and effectively. The expectation of the author is that the output of this research would foster the development and adaptation of EHRs management system.

The Jackson Prairie Region represents a rare, poorly understood and threatened ecosystem. A review of the literature concerning the ecology, physiography and geology of the Region was undertaken, along with a search of General Land Office (GLO) records for locations of historic prairie patches. The prairie patch location data was transcribed, digitized and inserted as a base map in a Geographical Information System (GIS). A set of current, local conditions indicating suitability for conservation or restoration, along with importance weights for each condition, was derived from stakeholder input. A simple additive weighting technique was used to rank the locations in terms of suitability for conservation or restoration. Historic patch locations were visited and the presence of prairie indicator species noted. The use of GLO records and GIS in this way improves the ability of landscape architects to enhance and preserve an imperiled habitat as they design across multiple scales.
