1	Organizacijos žinių valdymo informacinių sistemų integracija / Integration of organization knowledge management information systems Urbonas, Vytautas 30 May 2005 (has links) This work is aimed to analyze enterprise knowledge management system integration assumptions, problems and their solutions at different complexity and quality levels. In the beginning, brief description of application classification is provided. Assuming large number of specialized applications usage enterprise-wide, we come up with the need to integrate data, contained by those applications, as well as applications themselves. Data level, message level and process level integration principles and their application analysis is made. Enterprise application integration refers to the plans, methods, and tools aimed at modernizing, consolidating, and coordinating the computer applications in an enterprise. Portals presented as tools for federating information in different sources and providing commonly used services (search engine or directory, news, email, forums and options for customization). Portal frameworks from different vendors was observed. SOA (Service Oriented Architecture) and BPEL (Business Process Execution Language) integration capabilities were analyzed. Human Capital Resource Management information system is intended to store and process data, related to human capital across organization. Three layer logical implementation and web service interface usage makes integration possible at data, message and process levels.

2	Valor das capacidades de TI : impacto na qualidade da informação e no desempenho das organizações brasileiras Oliveira, Deyvison de Lima January 2013 (has links) O valor da Tecnologia da Informação (TI) para o negócio, na perspectiva de recursos isolados de TI, tem apresentado resultados mistos. Além disso, esse valor tem sido avaliado no nível da Firma, por meio de medidas agregadas de desempenho como rentabilidade, participação no mercado e eficiência. Como alternativa a essa abordagem, esta pesquisa adota o conceito de Capacidades de TI como um conjunto de recursos em uso pelas organizações. Também, outros construtos em níveis inferiores ao Desempenho da Firma (DF) são considerados – Qualidade da Informação (QI) e Desempenho no Nível de Processos (DP). Portanto, alternativamente às abordagens de valor da TI, esta pesquisa tem o objetivo de identificar o valor das Capacidades de TI e o seu impacto sobre a Qualidade da Informação e sobre o Desempenho Organizacional nos níveis de Processos e da Firma. O teste das hipóteses de pesquisa é precedido por entrevistas com especialistas de TI (gestores), no intuito de validar o modelo proposto. Adicionalmente, procedeu-se à tradução das variáveis para a survey. Especialistas em SI (pesquisadores) também participaram da avaliação das variáveis do modelo de medida, julgando sua permanência ou exclusão. Surveys Pré-teste e de Estudo Piloto foram realizadas com vistas ao refinamento do instrumento de coleta e do modelo de medida, respectivamente. Na survey completa participaram 150 gestores de TI e de negócios ligados a grandes organizações brasileiras. Os dados foram analisados com Modelagem de Equações Estruturais, a fim de validar o modelo de medida e testar as hipóteses do modelo. Pelo teste do modelo estrutural na survey completa, constatou-se que as Capacidades de TI Internas estão associadas ao nível de Qualidade da Informação e ao Desempenho no Nível de Processos. As Capacidades de TI Externas, por outro lado, não impactam positivamente na QI nem sobre os níveis de desempenho (Processos e Firma). Um modelo de mediação do Desempenho de Processos foi testado na survey completa. Constatou-se a mediação completa, sustentando a hipótese de que as Capacidades de TI Internas exercem impacto sobre o Desempenho da Firma, mediado por processos de negócio. Os resultados são apoiados por estudos que defendem que o valor da TI é captado direta e primeiramente em nível de Processos. As contribuições, limitações e recomendações da pesquisa constam nas Considerações Finais da tese. / The value of Information Technology (IT) to business, from the perspective of individual IT resources, has shown mixed results in the literature. Furthermore, this value has been evaluated at the firm level, through aggregate measures of performance such as profitability, market share and efficiency. As an alternative to such perspective, this research adopts the concept of IT Capabilities as a set of resources in use by organizations. Likewise, other constructs at lower levels than the Firm Performance are considered – namely Information Quality (IQ) and at the Process level Performance. So, alternatively to approaches about the value of IT, this research aims to identify the value of IT Capabilities and theirs impacts on the Information Quality and on the Performance, at the Processes and the Firm levels. The test of research’s hypothesis is preceded by interviews with IT specialists (managers) in order to validate the research model. Additionally, we proceeded to the translation of the variables for the survey. Information Systems experts (researchers) also participated in the evaluation of the variables to the measurement model, judging its presence or deletion. Surveys Pre-test and Pilot Study were conducted with a view to refining the data collection instrument and the measurement model, respectively. The full survey was answered by 150 IT’s and business’s managers in large Brazilian organizations. Data were analyzed with Structural Equation Modeling in order to validate the measurement model and testing hypotheses of the research model. For the test of the structural model in the full survey, it was found that the Internal IT Capabilities are associated with the level of Quality of Information and at the Process Level Performance. The External IT Capabilities, on the other hand, do not impact positively on IQ, neither on the performance levels (Processes and Firm). One model of mediation for Process level Performance was tested in the full survey. It was found full mediation, supporting the hypothesis that Internal IT Capabilities exert impact on the performance at the Firm level, mediated by business processes. The results are supported by researches that argue value of IT is captured direct and firstly at the Processes level. The contributions, limitations and recommendations of the research are contained in the end of the thesis.

5	Deregulation of the Swedish Audit Industry and Changes in the Competitive Environment : Conflict, Imitation, and Innovativeness Sebhatu, Abiel January 2011 (has links) This thesis investigates the deregulation of the audit industry in Sweden, the changing competitive environment and innovativeness, a research gap that has not yet been bridged. This paper raises the question of how the innovativeness of firms within the audit industry have changed after deregulation. The ambition of this research is to have both theoretical and practical knowledge contribution. The theoretical framework constructed for this research is rooted in the literature review of three areas: strategy and competition, deregulation, and organizational innovativeness. These three streams of research are used in order to examine the expectations that the industry has on the changing strategic landscape. Four perspectives and schools of thought in strategy and competition literature are reviewed: the competitive forces, strategic conflict school, resource-based school, and dynamic school. These schools are then put into two categories that are substantial opposites of one another; market power and efficiency. The need to consider these perspectives are addressed as follows: the perspective of competitive forces allows for understanding the industry structure, the strategic conflict school – to analyze the moves and interactions between competitors, the resource-based school – to understand firms resources, and finally, the dynamic school – to understand firms processes and capabilities. Summarizing and integrating these perspectives formed a hypothesized understanding that reflected the effects of deregulation and organizational innovativeness. In order to avoid modest pattern of deregulatory effects that could emerge by observations made in the early stage of deregulation, a methodological point of departure that is socially constructed and the production of knowledge that is based on interpretations and narratives were argued for. The research is furthermore based on a mix of deductive and inductive approach. The discussion with an industry member led to an interesting research context chosen as unit of analysis, which included the emerging tension between auditors and accounting-consultants. While the auditors’ believed in negative effects from the deregulation, the accounting-consultants had the opposite perception. Case-study approach with semi-structured and open-ended interviews were conducted on representatives from six firms, half of which represented the auditors and the rest the accounting-consultants. The presentation of results followed the structure of market power, efficiency, and organizational innovativeness. The analysis of the results shows how firms within the audit industry had changed during the transition towards post-deregulation era. It shows how the previous construction of the audit-industry, characterized by homogeneity, has been decomposed and transformed to become more heterogeneous, by the new attractions and alternatives that now exist on the market. These attractions and alternatives creates incitement for decreased interaction between competitors that causes firms to engage in conflicts, and to redistribute their resources in order to imitate each others processes, which in turn creates new organizational innovativeness. The findings of this research also shows how the resources that were possessed by the firm before the deregulation tend to determine how the firm utilize the innovativeness in relation to the market after the deregulation.

6	En studie i elevmotivation genom självreglerande lärande som metod för inlärning i moderna språk / A study on Learner Motivation by means of Learner Autonomy as Studying Technique in Modern Language Learning Gehrke, Karina Wiebke January 2022 (has links) Onödiga språkvalsbyten i moderna språk kan anses vara resultat av motivationsbrist kopplat till intrycket att glädje i språkvalsstudier inte leder till gymnasiebehörighet. Denna studie ämnar undersöka och fördjupa kunskap om a) samband mellan självreglering och elevmotivation, samt b) samband mellan glädje och motivation. Hattie och Zierer (2019) konstaterar att mer självreglering leder till ökad elevmotivation. För att pröva om denna slutsats kan verifieras, genomfördes en empirisk studie med lärarintervjuer som besvarade följande fråga: Vad anser lärare är en bra återkoppling till eleverna? För att kunna nå en slutsats i frågan om samband mellan självreglering och elevmotivation etablerades först en definition av begreppet självreglering. I detta syfte användes en teori som står för uppsatsens analytiska ramverk. Ramverket baseras på författare som arbetar i linje med Richard M. Ryans och Edward L. Decis Self-Determination Theory (SDT). Då slutsatsen att mer självreglerande lärande leder till ökad elevmotivation inte kunde verifieras i min empiriska studie, genomfördes en noggrann litteraturstudie. Utifrån denna kunde jag sedan göra en analys av mina frågeställningar med anslutande diskussion. Resultatet antyder att lärare bör fokusera på elevmotivationens kvalitet, med den prototypiska intrinsiska motivationen som mål, för att kunna motverka motivationsbristen i skolan. I detta forskningsarbete kom jag dessutom fram till slutsatsen att en högre motivation i allra högsta grad kan leda till ett mer effektivt lärande i allmänhet.
