- Abstract:
- The growing interest in the long-term performance of pile foundations and their ability to resist the negative effects of water exposure and aggressive soils has led to considering non-corrosive materials such as fibre-reinforced polymer (FRP). The most common applications are light-bearing structures in waterfront environments, while applications for larger structures have not been widely accepted in industry due to the lack of long-term records and design guidelines available. Previous research has primarily focused on the load transfer of concrete-filled FRP tubes—making it difficult to quantify the performance of FRP as a piling material on its own. In this study, a numerical model using the finite element method was developed to simulate small-scale load tests of hollow carbon-fibre reinforced polymer (CFRP) and glass-fibre reinforced polymer (GFRP) piles in soft clay. Verification of the model was attained using results from axial and lateral load tests on small-scale hollow CFRP and GFRP piles and pile-soil interaction was modelled using experimental data from interface shear tests conducted at Carleton University. A parametric analysis was performed to investigate and determine the key factors that influence the axial and lateral load response of hollow FRP piles. The findings of this research indicate that the number of FRP layers impacts loading behaviour significantly, while inner tube soil height has a reasonable influence on axial load response and fibre orientation has a minor effect under lateral load conditions.

- Abstract:
- The Canadian contribution and data set prepared as part of the Global Media and Internet Concentration (GMIC) project offers an independent academic, empirical and data-driven analysis of a deceptively simple yet profoundly important question: have telecom, media and internet markets become more concentrated over time, or less? Media Ownership and Concentration is presented from more than a dozen sectors of the telecom-media-internet industries, including film, music and book industries.

- Abstract:
- The COVID-19 pandemic has contributed to massive rates of unemployment and greater uncertainty in the job market. There is a growing need for data-driven tools and analyses to better inform the public on trends within the job market. In particular, obtaining a “snapshot” of available employment opportunities mid-pandemic promises insights to inform policy and support retraining programs. In this work, we combine data scraped from the Canadian Job Bank and Numbeo globally crowd-sourced repository to explore the relationship between job postings during a global pandemic and Key Performance Indicators (e.g. quality of life index, cost of living) for major cities across Canada. This analysis aims to help Canadians make informed career decisions, collect a “snapshot” of the Canadian employment opportunities amid a pandemic, and inform job seekers in identifying the correct fit between the desired lifestyle of a city and their career. We collected a new high-quality dataset of job postings from jobbank.gc.ca obtained with the use of ethical web scraping and performed exploratory data analysis on this dataset to identify job opportunity trends. When optimizing for average salary of job openings with quality of life, affordability, cost of living, and traffic indices, it was found that Edmonton, AB consistently scores higher than the mean, and is therefore an attractive place to move. Furthermore, we identified optimal provinces to relocate to with respect to individual skill levels. It was determined that Ajax, Marathon, and Chapleau, ON are each attractive cities for IT professionals, construction workers, and healthcare workers respectively when maximizing average salary. Finally, we publicly release our scraped dataset as a mid-pandemic snapshot of Canadian employment opportunities and present a public web application that provides an interactive visual interface that summarizes our findings for the general public and the broader research community.

- Abstract:
- Previous research has identified several likely causes of eligible non-participation in the Canada Learning Bond (CLB), including awareness, financial exclusion, and administrative barriers. This study expands on that research, with a particular focus on the role of tax-filing as an administrative obstacle to accessing the CLB. I present results from an online survey of low and modest income parents (n=466) conducted in 2021. We find that, even among parents reporting they have received the CLB (46%), a majority (51%) report low confidence in their familiarity with the program, and more than one in six (17%) are unaware of the need to file tax returns to maintain eligibility for annual CLB payments. Self-reported regular tax-filing is associated with a 59% increase in the probability of accessing the CLB, even when controlling for a range of parental characteristics. This study confirms previous work by Harding and colleagues (2019) that non-filing may explain some share of eligible non-participation in education savings incentives. Tax-filing services may be an important pathway to improve CLB access. Low and modest income parents show substantial diversity in their preferred filing methods and outreach efforts cannot be concentrated in only one avenue if they are to be successful. The study also tests a small ‘nudge’ to address gaps in awareness and finds that information-only approaches to outreach are likely to have limited success, even with motivated populations.

- Abstract:
- The digital economy, which was once considered as a panacea, is becoming increasingly viewed as a grand societal challenge – a problem that not only presents significant barriers to many people but is also so complex that it cannot be tackled by any one single organization. Mangers influence how the components of the global digital infrastructure, such as data analytics, artificial intelligence, and robotics impact society. However, mitigating the broad-gauged impacts of the digital economy, like its impact on the nature of work, would benefit from new ideas about manger’s roles in the digital economy. Framed in a management learning perspective, this study collates what we know, and what we need to know, about management and the digital economy. Overall, this paper suggests that managers need to learn new habits of thought to build a more balanced, equitable, and sustainable version of digital economy. Perspectives on how to design management learning environments to help managers think of, then implement, a digital ecosystem rather than a digital economy will contribute to ongoing debates about management learning that will advance positive transformations of the nature of work.
