Sharing the burden: Increasing the uptake of parental leave among fathers in Canada

Date created: 
2018-04-04
Abstract: 

This study evaluates policy options to increase the uptake of parental leave among fathers in Canada. Approximately 12% of fathers in Canada outside Quebec claim parental leave, while the majority of mothers claim leave. This imbalance in uptake leads to mothers taking on a larger share of work interruptions, which has negative impacts on their position in the workforce. A comprehensive case study analysis of Quebec, Norway, and Iceland is used to identify best practices and develop policy options. Three policy options are evaluated on five criteria. Results from the policy analysis indicate that a program similar to QPIP in Quebec should be implemented federally. This model includes a daddy-quota, higher compensation, lower eligibility criteria and increased flexibility. For the long-term I recommend dividing parental leave in three equal parts: one part for each parent, and one part that can be shared as they wish.

Yes oui can: Addressing British Columbia's shortage of French immersion teachers

Date created: 
2018-03-19
Abstract: 

French immersion offers students in British Columbia the opportunity to learn French as a second language, but since the program’s inception in the 1970s the province has faced a shortage of qualified teachers, with worrying consequences for both the quality of the program and the availability of spaces for students. This study explores this multi- faceted problem through a survey of school district and interviews with key stakeholders and experts. It describes several interrelated causes of the shortage and uses its findings to identify and analyze policy options to increase the supply of French immersion teachers in the province. The study recommends the implementation of professional development funding to help teachers transition to French, an informational campaign for French speaking students, and a student loan forgiveness program as solutions.

Estimating detection probability and detection range of radiotelemetry tags for migrating sockeye salmon (Oncorhynchus nerka) in the Harrison River, British Columbia

Date created: 
2018-03-01
Abstract: 

Radiotelemetry is a commonly used tool for tracking migration rates, estimating mortality, and revealing fish behaviour. However, researchers risk misinterpreting tag detection data by not appropriately accounting for signal detection probability or detection range of fixed antennas. In this study, I use generalized linear mixed effects models to estimate signal detection probability and detection range of six radiotelemetry tags at four fixed antenna sites. Detection probability differed among the four telemetry fixed sites despite identical techniques and similar receiver site equipment in a relatively small geographic area. The interaction of depth and distance demonstrated the greatest impact on detections at all sites. I conclude that rigorous testing of detection probabilities and detection range of test tags at individual receiver sites should be standard protocol for telemetry studies to optimize study designs and to ensure that appropriate inferences are drawn when telemetry data are used to support management decisions.

Non-standard work and access to unemployment benefits in Canada: Assessing policy options

Date created: 
2018-03-16
Abstract: 

Fewer than half of unemployed workers in Canada receive unemployment benefits. One of the reasons for this is that many workers in non-standard employment relationships, who represent a growing segment of the labour market, are excluded based on Employment Insurance (EI) eligibility criteria. EI was designed at time when standard employment relationships were far more prevalent and the system has not adapted to reflect the growth of part-time, temporary and self-employed work. Lack of access to unemployment benefits contributes to economic insecurity among non-standard workers, most of whom are women, low income and non-unionized. This study fills a gap in the literature by providing a comparative analysis of policy options for unemployment benefit reform with a focus on increasing access among workers in non-standard employment.

Policy makers or policy takers: How can cities contribute to reducing greenhouse gas emissions?

Date created: 
2018-04-26
Abstract: 

This study explores the implementation of community energy policy to reduce greenhouse gas emissions in Canada. There are two components to this study. The first is a modeling exercise which uses an energy-economy model to evaluate policies in terms of their greenhouse gas emissions reductions for the city of Victoria, British Columbia. While there is significant potential for Victoria to reduce emissions and fossil fuel use in some sectors, additional policy from the federal and provincial government will be needed to drive deep emissions reductions and fuel switching. The second component is a survey directed at community energy practitioners in Canada. It explores the use of tools such as the model used in this study to help inform the implementation of community energy policy. The preliminary findings suggest that while policy makers are open to the use of analytical tools for policy evaluation, significant barriers to executing these analyses and implementing their recommendations exist at the local level.

On the Nikolaevskiy equation and the fractal dimension of its attractor

Author: 
Date created: 
2018-04-23
Abstract: 

We investigate the attractor of the Nikolaevskiy equation, a sixth-order partial differential equation (PDE) containing a small parameter whose solutions exhibit spatiotemporal chaos with strong scale separation. We first prove well-posedness and regularity of the solutions, and derive asymptotic bounds on their derivatives, to put the subsequent results on a firm footing. The rest of the work focuses on showing that the dynamical system associated with the Nikolaevskiy equation possesses an attractor with a finite fractal dimension. Bounds on this dimension are both derived analytically and computed numerically, paying particular attention to their scaling with the parameters. We describe the numerical methods, and present computational results that include the scaling of various norms of the solutions, as well as of the power spectrum and the spectrum of Lyapunov exponents of the PDE.

Gaze training to improve mobility problems caused by glaucoma-related visual deficits

Date created: 
2018-04-23
Abstract: 

People with glaucoma collide with objects and fall more frequently than normally sighted individuals. Glaucoma-related visual field loss disrupts appropriate gaze behaviour, which is necessary for foot placement and route selection through cluttered environments. Thus, we developed a gaze training intervention to modify gaze behaviour. We taught (2, 1-hr sessions) older adults with glaucoma (n = 10) appropriate scanning and task-specific gaze strategies. To assess its effectiveness, participants performed a precision walking and obstacle avoidance task before and one-week after training. After training, participants shifted their gaze away from targets later relative to stepping on them and decreased foot-placement error and error variability. In the obstacle avoidance task, participants made more fixations before walking, shifted their gaze away from obstacles earlier with respect to crossing them, and had fewer obstacle collisions. Our results suggest that gaze is modifiable in older adults with glaucoma, and that gaze training may improve mobility.

Feeling you close to me: Mediating an infant's presence through an exploration of tactile interaction

Author: 
Date created: 
2018-04-19
Abstract: 

Touch is invaluable in parent-infant interactions, but there is a lack of research and design supporting tactile interaction in baby monitors. An exploratory study was conducted in the homes of 10 parents to understand the usage of baby monitors in everyday child-care routines. Parents’ responses revealed that the unfiltered videos in baby monitors require significant cognitive effort to interpret vital signals of their infants. In this thesis, I utilize a research-through-design approach that explores how tactile interaction can support a more direct communication channel to inform parents of their infants’ well-being and enhance presence in the computer-mediated connection. Four usability studies were conducted on four wearables prototypes that were iteratively designed. The final prototype, ombex, iterates from previous shortcomings and adopts pneumatic feedback to construct a more convincing association to breathing. Findings affirm that the tactile interaction using pneumatic feedback in ombex elicited an endearing connection as if a loved one is close by.

Transnational education in China: Joint venture Sino-US universities and their impact

Author: 
Date created: 
2018-04-23
Abstract: 

In recent years US universities have been diving into the Chinese higher education field by partnering with Chinese universities to create new joint venture Sino-US universities in China. From my field research interviewing students and professors at the NYU Shanghai and Duke Kunshan University campuses, I drew my main research questions: 1) What is the practical purpose of having JV Sino-US universities from the perspectives of the stakeholders – the home universities, governments, and students involved? 2) When we consider the ideal role and purpose of a university within society, what do these new transnational universities add to the conversation? I informed my research with the literature of international education, Chinese higher education, and critique of the modern Western university. From my research, I found that recruiting international students is a practical and value-laden challenge, and that the finances to support financial aid incentives may be an issue in the future. Concerning academic freedom, JVs have special privileges to operate in China with full freedom, but subtle issues of self-censoring or visas may still cause friction. Overall, these JV schools seem to suffer from the same issues that affect Western higher education in general, but they may be pioneers in re-evaluating liberal arts and discovering better ways to teach a broad range of students from different backgrounds.

Characterization of suppressors of fat-like cadherin CDH-4 in context of axon guidance during embryonic development

Author: 
Date created: 
2018-04-10
Abstract: 

Developing the nervous system requires axons to grow and connect to specific targets, forming neuronal circuits, through axon navigation. One of the genes controlling axon navigation is the fat-like cadherin CDH-4, a member of the cadherin superfamily. To identify genes acting together with cdh-4, mutants suppressing the axon guidance defects of cdh-4 mutants were isolated previously. The goal of this thesis was to characterize and identify these suppressor genes. Five suppressors were studied in detail. They partially suppressed axon guidance and movement defects observed in the cdh-4 mutants. Three suppressor genes were identified: math-48, a functionally uncharacterized gene, prp-6 and prp-8, both encoding components of the spliceosome. A previous study documented changes in expression of several hundred genes when prp-6 or prp-8 are partially inactivated. This suggests that the suppression effect might be mediated by upregulation of one or more genes, compensating for the loss of CDH-4.
