The aim of the thesis is to develop algorithm which will be able to optimize roles using RBAC model. The intent of the theoretical part is to analyze RBAC model and present current options which are available for role optimization. The practical part deals with development of algorithm which allows to optimize roles based on defined criteria from user. This algorithm is implemented in programming language Java and builds on Role Process Optimization Model (ROPM). In the last part is showed on example set of data how this algorithm works, step by step, with explanation of each step. Result of this algorithm is new RBAC model defined by user criteria. In this thesis are also listed different approach in role optimization, possible future development and concept of mapping RBAC model to mathematical and data-mining techniques.

This study seeks to understand how collaborative information communication technologies (cICT) are used to support knowledge translation and optimize physician’s roles in chronic pain management. A survey was developed and distributed to 170 physicians in two chronic pain mentoring networks in Ontario and Nova Scotia. With a response rate of 74.1% the study identified the use of a broad variety of cICTs; with email as the most used. A majority of respondents (85.0%) used email to support discussions and 69.8% found it to be valuable in learning about chronic pain management. A higher frequency of email (adjusted OR=10.70, 95% CI: 2.84-40.33) and number of cICTs (adjusted OR=2.93, 95% CI: 1.19-7.21) used to communicate in the networks were associated with more interactions. These results highlight how cICTs can support the interactions and learning that are part of the knowledge translation process in optimizing the roles of physicians in chronic pain management.

Background and Objectives: Recent immigrants experience unique challenges when accessing health services. Registered Nurses (RNs) working in primary health care (PHC) have the competencies and are well-positioned to facilitate healthcare access for immigrants. Aim: This study explored how PHC-RNs in Ontario support healthcare access and address barriers among recent immigrants. Methods: This study used a qualitative, interpretive descriptive approach and was informed by Levesque et al.’s (2013) access to care framework. Semi-structured interviews were conducted with 10 PHC RNs practising in Toronto, Ottawa-Gatineau, Hamilton, Kitchener-Cambridge-Waterloo, and London. Data were collected and analyzed concurrently using an inductive and deductive approach. Results: Findings show that PHC-RNs play instrumental roles in supporting recent immigrants through facilitating healthcare access across 9 dimensions of Levesque et al.’s (2013) access framework: (1) appropriateness, (2) availability and accommodation, (3) ability to perceive, (4) ability to engage, (5) ability to seek, (6) ability to reach, (7) affordability, (8) ability to pay, and (9) acceptability. RNs addressed significant challenges to health service access for recent immigrants, including language, geographical, and financial barriers. Several opportunities were identified to enhance the PHC RN clinical practice role to improve the delivery of PHC for recent immigrants, such as increasing organizational resources, utilizing their expertise and role beyond the PHC clinic, and promoting culturally appropriate care. Conclusions: PHC-RNs are key facilitators of healthcare access for recent immigrants by coordinating their care, educating, and connecting this population to services across the health system. However, there are opportunities to optimize nursing roles and more effectively utilize their scope of practice within interdisciplinary teams to promote the health of immigrants. / Thesis / Master of Science in Nursing (MSN)
