New research supports stricter social and economic mandates to reduce COVID-19 spread

As more people return to indoor settings for work and school, new research shows stricter policy restrictions on business operations and indoor mask-wearing reduced COVID-19 cases in Ontario during the first and second waves.

A new study led by researchers from the University of Waterloo found that stricter non-pharmaceutical interventions, such as policy restrictions on business operations and social gatherings, and indoor mask mandates, are associated with COVID-19 case reductions. Further, estimates based on publicly available Google mobility data suggest that increases in workplace attendance are correlated with higher case counts. 

“Public health measures such as mandatory mask use have become increasingly unpopular and divisive in society,” said Anindya Sen, a professor in the University of Waterloo’s Department of Economics. “However, our study offers evidence that these measures do work in reducing the incidence of disease. The results of the forecasting exercises should also be useful to policymakers from a planning perspective.”

In undertaking the study, the researchers used the Google data to assess the effects of public mobility to destinations commonly frequented, such as grocery and retail stores and workplaces. The researchers found that relatively simple forecasting models— known as “time-series models”—can predict one week ahead trends in daily COVID-19 cases in Ontario with some accuracy and are more precise than Ontario government forecasts. 

“Our models also offer more accurate daily forecasts than the susceptible-infected-removed model that epidemiologists typically employ,” Sen said. “Matching these mobility measures to corresponding trends in COVID-19 cases should be useful to policymakers in deciding specific types of economic and social lockdowns, as there are still gaps in knowledge on which types of population mobility are the most responsible for the spread of COVID-19 cases.” 

The study, Estimating the Effects of Non-Pharmaceutical Interventions (NPIs) and Population Mobility on Daily COVID-19 Cases: Evidence from Ontario, authored by Sen and Waterloo Department of Statistics and Actuarial Science colleagues Nathaniel Stevens, Francis Kiwon, Stefan Steiner, Plinio Morita from the School of Public Health Sciences, and University of Pennsylvania’s Qihuang Zhang, has been accepted for publication in the journal Canadian Public Policy.

Student Mental Health Research Conference inviting submissions

A message from Campus Wellness.

Campus Wellness will be hosting the University of Waterloo's second virtual Student Mental Health Research Conference on November 10, 2021, during Thrive. The goal of this event is to bring together members of the Waterloo community to share knowledge, connect researchers, and promote mental wellness. We are inviting submissions for presentations on student and emerging adult mental health, with an emphasis on the following key themes: 

• Promotion of mental health-care strategies;
• Suicide prevention; 
• Impact of trauma and sexual violence; 
• Equity and wellness (e.g., Indigenous approaches to wellness, effects of anti-Black racism, effects of sexual orientation and gender identity discrimination);
• Harm reduction approaches to substance use; and 
• Impact of COVID-19 on mental health. 

We will be accepting submissions from UWaterloo students, faculty, and staff until 11:59 p.m. on October 12, 2021. Visit the Thrive website to submit your abstract.

Hack the North taps into tech

By Jon Parsons.

Most students develop an interest in technology and programming long before they begin their post-secondary education.

The path to becoming a developer, analyst or software engineer does not usually start in a computer science course at university, but in the opportunities available to students outside the classroom.

Hack the North is just this kind of event that allows students to gain valuable skills, learn about the tech industry’s culture and network with like-minded peers who share their interests.

“Hack the North exists to give anyone the ability and the opportunity to dream big,” said Jessica Zhang, one of the co-directors of the event. “Whether that’s through workshops or mentorship, whether that’s through the speaker panels or networking, we’re connecting people and giving them a space and the resources to build something amazing.”

Bringing together more than 3,000 students from Canada and around the globe, Hack the North is a unique student-led hackathon. In its eighth year, the event operates in partnership with the Faculty of Mathematics and the Faculty of Engineering at the University of Waterloo. The two faculties provide ongoing logistical support and funding.

Hack the North is sponsored by some of the biggest and most innovative global and local tech brands, including Hootsuite, Facebook, Google, Cisco, D2L and Ubisoft.

Emily Wang, the other co-director, said the partnerships and sponsorships are instrumental in the success of Hack the North. Some sponsors also provide access to exciting application programming interfaces (APIs), which participants can use to create apps.

“Hackers are free to use whatever technology or platform they want during the event, so we don’t have any limitations or restrictions in that way,” Wang said. “But we do have certain sponsors that have their own APIs that hackers can use, and there are special API prizes as well.”

Even as many participants in Hack the North will enter the event with significant background and experience in tech and programming, there are also many beginners. The hackathon caters to all skill levels. This year, Hack the North features a “Gear Up week,” which runs five days before the main event kicks off and is open to the public.

As Wang explains, Gear Up has some “30 plus workshops to help participants gain new skills and be ready to build their project in the hackathon, instead of learning everything during the weekend of the event.” 

Along with its egalitarianism and welcoming of new and experienced hackers alike, Hack the North is organized by students, for students. Zhang is currently enrolled in the computer engineering program at the University of Waterloo. Wang is likewise an undergraduate student in Waterloo’s system design engineering program. Students make up all the volunteers and various organizing committees.

As a student-led and student-organized event, Hack the North has a distinctive character among hackathons. The mandate for the annual event extends beyond learning tech skills to focus on equity, diversity and inclusion in the tech industry writ large. Organizers put the event together so that participants get to meet and work with students from different backgrounds and with different experiences. And throughout the event’s 36 hours, there are numerous side activities and breakout groups so students can meet one another and simply make new connections.

“We have the ability to set the tone and to show hacking can be a way to help underrepresented groups find their place in tech and continue along that path,” said Zhang. “Hack the North is one of the bigger and more established hackathons in the North American hackathon sphere, which means we can be role models for other hackathons. Diversity, equity and inclusion are really important to our organizing team and the whole event. This year we’re focusing on this aspect even more and trying to make strides in that area.”

Every year, Hack the North features special guests and speakers, which have included tech industry leaders, CEOs, and luminaries. Some of these same special guests may also act as judges for the various apps and programs the students create in the hackathon or join student groups as mentors.

This year’s speakers and special guests are something of a guarded secret, so anyone interested should look for ways to get involved. Hack the North 2021 runs from Friday, September 17, to Sunday, September 19. Visit the Hack the North website for more information.
