Implementation of Marine Protected Areas as a governability challenge in Southern Brazil

Marine Protected Areas (MPAs) have been endorsed internationally as a tool promoting marine conservation. MPAs implementation can however be challenging, with many not achieving conservation objectives while creating conflicts with small-scale fishers, often overlooked. This study aims at exploring how MPA implementation can be improved, taking as a case study the Marine National Park of Currais Islands in Southern Brazil. Specifically, this thesis offers a theoretical contribution by applying the interactive governance framework to analyze both the natural and the social systems, focusing on small-scale fishers, governed by the MPA as an institution. The thesis also presents a methodological contribution, as it develops and applies an exploratory mapping approach. We surveyed 65 small-scale fishers from eight communities at Pontal do Paraná municipality, and conducted an exploratory mapping approach in small groups. Main findings point to challenges and opportunities to MPA implementation, and offer a way to involve small-scale fishers in the discussion about MPAs.

Supporting inclusiveness through concepts of gender

Some dads wear nail polish! Is the tooth fairy a boy or a girl? My Grade Two students’ voices were integral in developing each of the action research cycles as students became co-creators of knowledge. I gathered data through a personal journal, observations, reflections, work samples, interviews and classroom artifacts. The research question was focused on creating a safe and caring classroom environment by selecting appropriate instructional strategies based on developing my students’ concept of gender. Findings included students’ acceptance of differences, emulation of gender stereotypes, the significance of role models and student empowerment. Conclusions examined the influence that behaviour has on instructional strategies, creating allies among primary students, the importance of teacher training and the influence that students have in their classroom. Thoughts towards future research include the need for further parent engagement and more exploration of the impact that the school environment has in the classroom.

Dynamic safety analysis of managed pressure drilling operations

The exploration and development of oil and gas reserves located in harsh offshore environments are characterized with high risk. Some of these reserves would be uneconomical if produced using conventional drilling technology due to increased drilling problems and prolonged non-productive time. Seeking new ways to reduce drilling cost and minimize risks has led to the development of Managed Pressure Drilling techniques. Managed pressure drilling methods address the drawbacks of conventional overbalanced and underbalanced drilling techniques. As managed pressure drilling techniques are evolving, there are many unanswered questions related to safety and operating pressure regimes. Quantitative risk assessment techniques are often used to answer these questions. Quantitative risk assessment is conducted for the various stages of drilling operations – drilling ahead, tripping operation, casing and cementing. A diagnostic model for analyzing the rotating control device, the main component of managed pressure drilling techniques, is also studied. The logic concept of Noisy-OR is explored to capture the unique relationship between casing and cementing operations in leading to well integrity failure as well as its usage to model the critical components of constant bottom-hole pressure drilling technique of managed pressure drilling during tripping operation. Relevant safety functions and inherent safety principles are utilized to improve well integrity operations. Loss function modelling approach to enable dynamic consequence analysis is adopted to study blowout risk for real-time decision making. The aggregation of the blowout loss categories, comprising: production, asset, human health, environmental response and reputation losses leads to risk estimation using dynamically determined probability of occurrence. Lastly, various sub-models developed for the stages/sub-operations of drilling operations and the consequence modelling approach are integrated for a holistic risk analysis of drilling operations.

The current state of /L/ allophony in St. John's English

This project examines the use and evaluation of light post-vocalic /l/ in St. John's, Newfoundland. The city, which was primarily settled by the Irish, traditionally did not conform to the Standard Canadian pattern of /l/ allophony. That is, it was reported to have light /l/ in all positions, in contrast to Canadian English, which has dark /l/ in codas and light /l/ in onsets (Clarke 2012). There have been, however, several major social and economic changes in Newfoundland since the mid-twentieth century, which have impacted local dialects (Clarke 2010). In terms of postvocalic /l/, data collected by Clarke in St. John's in the 1980s shows that the light variant is declining in use and being replaced by the dark variant, and that little overt awareness is accompanying this change (2012). This study addresses the decline and awareness of this feature, through production and perception experiments, respectively. This work follows that of Clarke in that it looks at younger age groups that have been born since Clarke's study was conducted in the early 1980s. The results of these experiments suggest that the light post-vocalic /l/ has continued its decline in St. John's English, and that the dark variant is a stable norm. In fact, it is light /l/ in initial position that is experiencing social variation, in that younger speakers are using darker /l/s in this position than their older counterparts. Women, though they display a more standard /l/ allophony pattern overall than men, also show more dramatic initial-/l/ darkening in apparent time. Additionally, there is a significant style shift between word list and interview tasks in this position. The perception experiment shows that there is awareness and stigma associated with the light variant in coda, which could extend to light /l/s in general.

Experimental investigation of water, snow and granular ice effects on ice failure processes and impact loads

A large series of laboratory ice crushing experiments was performed to investigate the effects of external boundary condition and indenter contact geometry on ice load magnitude under crushing conditions. Four boundary conditions were considered: dry cases, submerged cases, and cases with the presence of snow and granular ice material on the indenter surface. Indenter geometries were a flat plate, wedge shaped indenter, (reverse) conical indenter, and spherical indenter. These were impacted with artificially produced ice specimens of conical shape with 20° and 30° cone angles. All indenter – ice combinations were tested in dry and submerged environments at 1 mm/s and 100 mm/s indentation rates. Additional tests with the flat indentation plate were conducted at 10 mm/s impact velocity and a subset of scenarios with snow and granular ice material was evaluated. The tests were performed using a material testing system (MTS) machine located inside a cold room at an ambient temperature of - 7°C. Data acquisition comprised time, vertical force, and displacement. In several tests with the flat plate and wedge shaped indenter, supplementary information on local pressure patterns and contact area were obtained using tactile pressure sensors. All tests were recorded with a high speed video camera and still photos were taken before and after each test. Thin sections were taken of some specimens as well. Ice loads were found to strongly depend on contact condition, interrelated with pre-existing confinement and indentation rate. Submergence yielded higher forces, especially at the high indentation rate. This was very evident for the flat indentation plate and spherical indenter, and with restrictions for the wedge shaped indenter. No indication was found for the conical indenter. For the conical indenter it was concluded that the structural restriction due to the indenter geometry was dominating. The working surface for the water to act was not sufficient to influence the failure processes and associated ice loads. The presence of snow and granular ice significantly increased the forces at the low indentation rate (with the flat indentation plate) that were higher compared to submerged cases and far above the dry contact condition. Contact area measurements revealed a correlation of higher forces with a concurrent increase in actual contact area that depended on the respective boundary condition. In submergence, ice debris constitution was changed; ice extrusion, as well as crack development and propagation were impeded. Snow and granular ice seemed to provide additional material sources for establishing larger contact areas. The dry contact condition generally had the smallest real contact area, as well as the lowest forces. The comparison of nominal and measured contact areas revealed distinct deviations. The incorporation of those differences in contact process pressures-area relationships indicated that the overall process pressure was not substantially affected by the increased loads.

The process of implementing a new baby-friendly hospital initiative for nurses: a grounded theory study

Maternity nursing practice is changing across Canada with the movement toward becoming “baby friendly.” The World Health Organization (WHO) recommends the Baby-Friendly Hospital Initiative (BFHI) as a standard of care in hospitals worldwide. Very little research has been conducted with nurses to explore the impact of the initiative on nursing practice. The purpose of this study, therefore, was to examine the process of implementing the BFHI for nurses. The study was carried out using Corbin and Strauss’s method of grounded theory. Theoretical sampling was employed, which resulted in recruiting and interviewing 13 registered nurses whose area of employment included neonatal intensive care, postpartum, and labour and delivery. The data analysis revealed a central category of resisting the BFHI. All of the nurses disagreed with some of the 10 steps to becoming a baby-friendly hospital as outlined by the WHO. Participants questioned the science and safety of aspects of the BFHI. Also, participants indicated that the implementation of this program did not substantially change their nursing practice. They empathized with new mothers and anticipated being collectively reprimanded by management should they not follow the initiative. Five conditions influenced their responses to the initiative, which were (a) an awareness of a pro-breastfeeding culture, (b) imposition of the BFHI, (c) knowledge of the health benefits of breastfeeding, (d) experiential knowledge of infant feeding, and (e) the belief in the autonomy of mothers to decide about infant feeding. The identified outcomes were moral distress and division between nurses. The study findings could guide decision making concerning the implementation of the BFHI.

My answers are based on a literature review, data analysis from previous experiments, and a SWOT analysis. I will conclude by recommending a course of action for Grenfell that will move it toward using more renewable energy, and becoming a local resource for alternative energy solutions.

Patterns in personal experience narratives: storytelling at cod harbour - a Newfoundland fishing community

This study is concerned with storytelling as a part of the folk culture of a fishing community on the north east coast of Newfoundland. The study is based on field work done in the community throughout the summer of 1969 during which I tape recorded oral narratives along with other folklore and folklife material . The principal genre discussed is the personal experience narrative which is an account of the experiences of either the narrator, someone in his kin network, orhis friends. It was found that a large number of community residents communicate in narrative form and that the narratives function to substantiate conversation preceeding the narrativei have a didactic function; function as a means of entertainment~ and reflect the narrators' and the community's value system. The methods employed in collecting the material were the directive and the non-directive interview techniques and participant observation. Collecting was done mainly among fishermen between fifty and eighty years of age and who, on -the average, had not gone beyond the sixth grade in school. Since the narratives are so much a part of the environment, I give an account of the community culture. The principal things that I deal with are the community's history, economy, education, religion, and social life which includes rites of passage, calendar customs , social events, visiting patterns, and gossip. Information in each of these categories is based primarily on oral reports, narratives and documented materials. After a discussion of the storytelling process in the community, I deal specifically with four male narrators. For each I give biographical information, discuss his repertoire, telling situations, style, and give a sampling of his narratives. The fourth narrator is discussed in more detail than the first three. The narratives of the latter comprise the final chapter in the study, and have been analyzed to show what they tell us about the narrator's style, his value system, and the community culture.

Use of active power filter to reduce the effects of harmonics in solid oxide fuel cells

The Solid Oxide Fuel Cell (SOFC) is a class of fuel cells that is capable of generating very high levels of power at high temperatures. SOFCs are used for stationary power generation and as Combined Heat and Power (CHP) systems. In spite of all the beneficial features of the SOFC, the propagation of ripple currents, due to nonlinear loads, is a challenging problem, as it interferes with the physical operation of the fuel cell. The purpose of this thesis is to identify the cause of ripples and attempt to eliminate or reduce the ripple propagation through the use of Active Power Filters (APF). To this end, a systematic approach to modeling the fuel cell to account for its nonlinear behavior in the presence of current ripples is presented. A model of a small fuel cell power system which consists of a fuel cell, a DC-DC converter, a single-phase inverter and a nonlinear load is developed in MATLAB/Simulink environment. The extent of ripple propagation, due to variations in load magnitude and frequency, are identified using frequency spectrum analysis. In order to reduce the effects of ripple propagation, an APF is modeled to remove ripples from the DC fuel cell current. The emphasis of this thesis is based on the idea that small fuel cell systems cannot implement large passive filters to cancel the effects of ripple propagation and hence, the compact APF topology effectively protects the fuel cell from propagating ripples and improves its electrical performance.

Evaluation of a One-Day Meditech Magic Training Program for Registered Nurses and Licensed Practical Nurses in a long term care program

Background: An evaluation was completed on the One-Day Meditech Magic Training Program for Registered Nurses (RNs) and Licensed Practical Nurses (LPNs) developed for the Long Term Care (LTC) Program. Methods: Both a literature review and consultation with stakeholders were completed to determine possible evaluation methods, expected outcomes, and ways to measure the effectiveness of the education program. A pretest/posttest design and questionnaire were chosen as the evaluation tools for this project. Results: No significant difference was found between the pretest and posttest total scores indicating that learners retained information from the orientation session (Z = -1.820, p = 0.069). Additional Wilcoxon matched-pairs signed rank tests were performed on the individual sections of the tests and revealed a significant decrease in the posttest scores for entering a Diagnostic Imaging requisition (Z = -1.975, p = 0.048). No other significant findings were present. Questionnaires were also analyzed revealing that most participants were pleased with the Meditech documentation education they received and did not indicate barriers that would affect electronic documentation. Conclusions: Further testing is required to ensure reliability and validity of the evaluation tools. Finally, caution is needed due to a small sample size. However, problematic documentation tasks were identified during the evaluation, and as a result both the training session and support materials will be improved as a result of this project.

The impact of income and social status on population health: a scenario based simulation for nursing students

The development of critical thinking and communication skills is an essential part of Baccalaureate and Practical Nursing education. Scenario-based simulation, a form of experiential learning, directly engages students in the learning process. This teaching learning method has been shown to increase students’ understanding of the influence of their personal beliefs and values when working with clients and to improve therapeutic communication and critical thinking skills. Students in both the BN (Collaborative) and PN Programs at the Centre for Nursing Studies demonstrate a strong theoretical understanding of the impact of income and social status on population health but often experience difficulty applying this knowledge to the clinical situations involving clients and families. The purpose of the project was to develop a scenario-based simulation activity to provide nursing students with first-hand experiences of the impact of income and social status on health service accessibility. A literature review and stakeholder consultations were conducted to inform the project. The findings of these initiatives and Kolb’s Experiential Learning Theory were used to guide all aspects of the project. This report is an account of how the income and social status simulation and its accompanying materials were developed. This project provided an excellent learning opportunity that demonstrated the use of advanced nursing competencies.

The development of an online neonatal intensive care unit family education

Background: British Columbia’s Fraser Health Authority (FHA) neonatal intensive care units (NICUs) value family centered care (FCC). Nevertheless, there is limited evidence that FCC is actually incorporated into practice, as well as some concern that FHA NICU education is inaccessible, inconsistent, or disorganized. Purpose: The mission of this project is to support the principles of FCC throughout the development of an FHA online NICU family education guide by reflecting upon the needs of families throughout their NICU journey. Methods: A needs assessment was initially completed and included literature reviews, consultations, and an environmental scan. This data informed development of an online NICU family education guide which plots current education materials along key stages of the NICU journey: prenatal, admission, early days, growing and developing, discharge and at home. For the purposes of this practicum, only the prenatal stage was fully developed and will serve as a template for other stages following a formative evaluation. A pamphlet and revised FHA Neonatal Checkpoint will also be developed to augment teaching by health care professionals. Implementation and evaluation plans were adapted from the Center for Disease Control Framework for Program Evaluation in Public Health. Results: The needs assessment validates and directs the development, implementation, and evaluation of the online guide illustrating an FCC approach. The online guide centralizes and organizes education by selecting education topics that relate to each stage of the NICU journey. This family-directed design enables families’ access to consistent and reliable information and offers them an opportunity to learn at their own pace. Conclusion: The process of creating, implementing, and evaluating an online family education program for FHA NICUs elucidates the intricacies and the advantages of integrating FCC into NICU practice.

Development of an education resource for families and clients navigating through end-of-life care with at-home palliation

Background: Community health nurses (CHNs) play a pivotal role in providing end-of-life care to clients diagnosed with a life-threatening illness. Providing quality end-of-life care is an ethical obligation. Eastern Health’s palliative end-of-life care program (PEOLC) offers nursing care, equipment, services, and support. However, the caregiver’s need for practical information about end-of-life issues is not addressed. Purpose: To develop an educational resource to assist clients and families during end-of-life and to provide a framework for new CHNs in home palliation. Methods: An informal Needs Assessment, a literature review, an environmental scan, and consultations with four CHNs involved with home palliation. Results: An educational resource was developed to address the practical end-of-life issues identified in the literature review and consultations. Conclusion: An improved delivery of care for at-home palliation in the community for clients and families, and a framework for new CHNs.

Development of a learning resource manual for nurses new to thoracic surgery

Background: Patients with lung and esophageal cancer often have surgery as a means of treatment. In Newfoundland and Labrador, patients with lung and esophageal issues are cared for on Six East, the General/Thoracic Surgery unit at St. Clare’s Mercy Hospital. These patients frequently require chest tubes, which are managed and assessed by Registered Nurses (RNs) on the unit. For nurses new to thoracic surgery, fulfilling their new role and caring for chest tube systems can be daunting. Purpose: The purpose of this practicum project was to develop a learning resource manual for nurses who are new to thoracic surgery. Via self-directed learning, the manual can increase the knowledge and self-efficacy of nurses who are caring for thoracic surgery clients and assessing chest tube systems. Methods: An informal needs assessment, integrated literature review, and several consultations via in-person interviews were conducted. Results: Based on the findings from these methodologies, Knowles’ Adult Learning Theory, and Benner’s Novice to Expert Model, a learning resource manual was created. The manual was divided into chapters covering various aspects of patient and chest tube system care and assessment. Conclusion: For the purpose of this practicum project, no evaluation was conducted. However, a plan for future evaluation of the learning resource manual has been developed to determine if the manual assisted with increasing the knowledge and self-efficacy of nurses new to thoracic surgery. “Test Your Knowledge” questions were included at the end of each chapter in the manual as well as case study scenarios to allow for participant self-evaluation.
