Since the 1990s, Knowledge Management Systems (KMS) have been largely unsuccessful in the collection of tacit knowledge. The process, whether through direct input by the holder of the tacit knowledge or through an intermediary such as the collection of tacit knowledge through interviews and videos, has not succeeded. Reasons encompass the organizational (such as culture of the organization), the technological (example: poor tools), and the individual (example: knowledge is power, i.e. where experts with rare knowledge results in knowledge hoarding instead of transfer). The purpose of this study was to demonstrate that tacit knowledge could be successfully and consistently collected from the participants themselves and placed into a KMS using a storytelling-based approach. This study extended past research that collected stories for KMS’ using interviews and videos by having participants directly entering their data, as stories, into a KMS. This was a new approach and it was posited that having participants use stories to enter their tacit knowledge themselves into a KMS would overcome their reluctance to provide tacit knowledge thus overcoming barriers to providing tacit knowledge into a KMS The validation methodology was based upon three elements: the deep-dive research element, the issues and solution element, and the dissertation proposition element. The deep-dive research element was the extensive research for the study into knowledge management, storytelling, and other various methods for collection of tacit knowledge. The issues and solution element consisted of issues about tacit knowledge that were identified from the deep-dive research element, i.e. general arguments constructed about knowledge management which were backed by data from research into knowledge management systems and storytelling. Theoretical solutions to the issues regarding the capture of tacit knowledge were then constructed which included the storytelling-based approach and a KMS framework for the collection of tacit knowledge. Lastly was the dissertation proposition element which consisted of a thorough analysis of the survey data against each of the dissertation propositions. There were three propositions. Proposition 1 was sharing of knowledge and the storytelling-based approach. Proposition 2 was about the framework, the scenarios, guiding questions, and Communities of Practice (CoP), and Proposition 3 was about participant knowledge and interaction with forums. Each proposition was evaluated independently. The study was successful and validated propositions 1 and 2. For proposition 1, 81% of the participants responded positively to the eight study questions directed towards this proposition. For all eight questions across all 21 participants, the mean was 29.952 against a target test mean of 24 with a range of 27.538-32.367. For proposition 2, 76.19% of participants scored this section positive. For all six questions across all 21 participants, the mean was 23 against a target test mean of 18 with a range of 21.394-24.606. However, the results for proposition 3 were inconclusive and must be considered a failure. Most of the respondents either scored ‘no change’ to at least 50% of the questions or they stated they had never been to a forum. For all four questions across all 21 participants, the mean was 12.905 against a target mean of 12 with a range of 11.896-13.914. Based upon propositions 1 and 2, the null hypothesis was disproved. Participants liked the storytelling-based approach, providing their tacit knowledge, and they liked the framework.

Knowledge Management System (KMS) is a necessary concept as knowledge possessed by each individual employee is an intellectual property asset that will provide benefits for any organization. In a company, in terms of KMS, employees’ performance holds an important role in helping run the business of the company becoming sustainable and successful. Therefore, the measurement of employees’ performance based on a balanced scorecard is needed to understand the current business situation. This research helped focus on the perception between the KMS and employee’s performance based on a balanced scorecard (BSC) regarding a financial perspective, customer perspective, internal business process perspective, and learning & growth perspective. A survey was conducted at PT. Vale Indonesia Tbk (Vale) to ascertain these perspectives and perceptions of employees regarding performance based on a BSC. These perception data were analyzed, and conclusions were drawn regarding hypotheses. The findings section of this thesis shows the results in details. The results of the survey showed that the employees had a good perception of the value and benefits of KMS as measured with the BSC with the exception of the financial aspect. The interpretation of the results created recommendations to further implement KMS, and to improve employees’ performance at Vale.

More than 38% of the U.S. public workforce will likely retire by 2030, which may result in a labor shortage. Business leaders may adopt strategies to mitigate knowledge loss within their organizations by capturing knowledge in a knowledge management system (KMS). The purpose of this single case study was to explore strategies that information technology (IT) managers use to develop and implement a KMS. The target population consisted of IT managers in a small-sized organization located in northwestern Florida who had implemented a KMS successfully. The conceptual framework for this study was organizational knowledge creation theory. The collection of public documents, execution of semistructured interviews with 5 qualified participants, literature on the topic, and member checking formed the determination of the findings of the study. Using triangulation and coding the data for emergent themes, 6 themes emerged from the data analysis: (a) training, (b) customer focus, (c) policy and governance, (d) leadership and management support, (e) communication and marketing, and (f) business process management. The application of the findings may contribute to social change by identifying strategies that leaders and IT managers from communities and government agencies use in implementing a KMS that may facilitate transparency and open flow of information to citizens, and allow access to timely, civic, and potentially life-enhancing information.

Nous proposons une dérivation théorético-informationnelle de la théorie quantique via une axiomatique informationnelle. La 1ère partie de la thèse est consacrée aux fondements philosophiques de cette approche. Elle est présentée dans un cadre épistémologique sous la forme d'une boucle entre descriptions théoriques. La 2ème partie est consacrée à la dérivation du formalisme de la théorie quantique. Nous posons un système d'axiomes et nous analysons le double rôle de l'observateur. A l'aide des techniques de la logique quantique, nous établissons les théorèmes montrant les étapes de la reconstruction du formalisme de la théorie quantique. Dans la 3ème partie, nous introduisons la théorie des C*-algèbres et nous proposons de cette dernière une interprétation théorético-informationnelle. Nous concluons par une liste de problèmes ouverts dans l'approche informationnelle, y compris ceux relevant des sciences cognitives, de la théorie de la décision et des technologies de l'information.

Polycyclic aromatic hydrocarbons, produced by anthropological and natural activities, are hazardous through formation of oxidative radicals and DNA adducts. Growth of Mycobacterium sp. strain KMS, isolated from a contaminated soil, on the model hydrocarbon pyrene induced specific proteins. My work extends the study of isolate KMS to the gene level to understand the pathways and regulation of pyrene utilization. Genes encoding pyrene-induced proteins were clustered on a 72 kb section on the KMS chromosome but some also were duplicated on plasmids. Skewed GC content and presence of integrase and transposase genes suggested horizontal transfer of pyrene-degrading gene islands that also were found with high conservation in five other pyrene-degrading Mycobacterium isolates. Transcript analysis found both plasmid and chromosomal genes were induced by pyrene. These processes may enhance the survival of KMS in hydrocarbon-contaminated soils when other carbon sources are limited. KMS also grew on benzoate, confirming the functionality of an operon containing genes distinct from those in other benzoate-degrading bacteria. Growth on benzoate but not on pyrene induced a gene, benA, encoding a benzoate dioxygenase α-subunit, but not the pyrene-induced nidA encoding a pyrene dioxygenase α-subunit; the differential induction correlated with differences in promoter sequences. Diauxic growth occurred when pyrene cultures were amended with benzoate or acetate, succinate, or fructose, and paralleled delayed expression of nidA. Single phase growth and normal expression of benA was observed for benzoate single and mixed cultures. The nidA promoters had potential cAMP-CRP binding sites, suggesting that cAMP could be involved in carbon repression of pyrene metabolism. Growth on benzoate and pyrene requires gluconeogenesis. Intermediary metabolism in isolate KMS involves expression from genes encoding a novel malate:quinone oxidoreductase and glyoxylate shunt enzymes. Generation of C3 structures involves transcription of genes encoding malic enzyme, phosphoenolpyruvate carboxykinase, and phosphoenolpyruvate synthase. Carbon source modified the transcription patterns for these genes. My findings are the first to show duplication of pyrene-degrading genes on the chromosome and plasmids in Mycobacterium isolates and expression from a unique benzoate-degrading operon. I clarified the routes for intermediary metabolism leading to gluconeogenesis and established a potential role for cAMP-mediated catabolite repression of pyrene utilization.

<p><em>Knowledge has become one of the most important assets for companies nowadays. Knowledge Management (KM) uses organizational knowledge as a resource to make companies more competitive. Knowledge Management Systems (KMS) are gaining popularity, however, the failure rate remains high, with many projects not achieving their goals or being shut down early. KMS are often underestimated and treated as normal systems. IS practices do not cover certain aspects specific to KMS, aspects that do not show in other IS (e.g. socio-cultural issues). There are many studies concerning the KMS failures but they just focus on the symptoms and do not provide a solution to the problem. The goal of this master’s dissertation is to generate a preventive tool that will help the KM field. With The experience gained by working in a real KMS project within a textile agency in Sweden and relevant literature, an Information Systems Design Theory (ISDT) for KMS was developed. As some authors suggest, KM needs an ISDT of it’s own. An ISDT will guide practitioners through the process by restricting practices and features of the system to a more effective set. It will also encourage the academia to work on this theory for its improvement, completion, and validation</em></p>
