Short Courses

View our CEW 2023 short course offerings below.

WORKSHOP: EMERGING GOOD PRACTICES IN BRINGING TOGETHER INDIGENOUS AND SCIENTIFIC WAYS OF KNOWING 

Laura S. Lynes, Henry (Harry) Penn | Resilience Institute

In-Person | Monday, October 2nd, 13:00 - 15:00

Choose “short course ticket” for the most stream-lined process if you have already registered for the conference.

In this session we will discuss emerging principles and practices in bringing together western trained and Indigenous experts, and in weaving together different ways of knowing and doing based on values from different perspectives. We invite attendees to bring an example of a good practice from their work, or an example of a not-so-good attempt at this work with their reflections for our collective learning. No experience is necessary, everyone is welcome to learn and participate. Prior to our time together we may circulate questions for reflection and a suggested format for sharing examples. 

WORKSHOP: BLANKET EXERCISE

Elder Barbara Dumont-Hill, Larry Hill

In-Person | Monday, October 2nd, 15:30 - 17:30

Choose “short course ticket” for the most stream-lined process if you have already registered for the conference.

The Blanket Exercise is an experiential workshop facilitated by Elder Barbara Dumont-Hill and Larry Hill. The workshop will help participants understand how the colonization of this land has impacted and continues to impact ourselves, our families, our communities, and Indigenous and non-Indigenous nations. The workshop will include an introduction, the Blanket Exercise and a sharing circle. There is no cost for participants, however, registration is required due to limited space.

RISK COMMUNICATION IN A CHANGING WORLD

Ronald W. Brecher, Trevor Smith Diggins | RiskPartners

Virtual, Half Day | Monday, October 2nd, 09:00 - 12:00

The pandemic has changed the way we talk about science. The communication landscape has shifted. Disinformation spreads faster than a virus, leading to increased fear and outrage. Many of our stakeholders don’t know who to trust anymore. This workshop introduces a disciplined, methodical framework for communicating effectively about risk. Our proven approach can help you build credibility, cut through the noise, and encourage constructive stakeholder engagement.


Workshop Objectives:

 

  • Examine factors affecting trust and credibility of spokespersons and key resource personnel, such as subject matter experts and the organizations they represent.

  • Learn the principles of effective messaging to communicate the organization’s position on issues related to risk, using plain language suitable for diverse audiences.

  • Improve skills for understanding and delivering information in times when your audience may be experiencing high concern and low trust.

  • Develop strategies to work effectively with stakeholders and the media.

DEVELOPMENT AND IMPLEMENTATION OF
CANADIAN ENVIRONMENTAL QUALITY GUIDELINES

Janet Cermak, Allison Dunn, Tamzin El-Fityani, Bill Martin
National Guidelines and Standards Office, Science and Technology Branch, Environment and Climate Change Canada

In-Person, Full Day | Monday, October 2nd, 09:00 - 16:00

The goal of this full day workshop is to provide attendees with the background, guiding principles, data requirements, derivation procedures, and application of Canadian environmental quality guidelines (CEQGs). CEQGs are developed following Canadian Council of Ministers of Environment (CCME) protocols. They are developed to either protect the ambient environment (e.g., guidelines for the protection of aquatic life, wildlife diet) or for the assessment and remediation of contaminated sites (e.g., soil quality, groundwater and soil vapour guidelines). The CCME protocols will be described and discussed. Participants will gain an understanding of the purpose, derivation methods and implementation of environmental quality guidelines. An introduction to site-specific considerations will also be provided.

R WORKSHOP: ANALYZING ENVIRONMENTAL DATA
WITH NUMEROUS NON-DETECTS

Zofia Taranu | Environment and Climate Change Canada

In-Person, Half Day | Monday, October 2nd, 09:00 - 12:00

The workshop will provide an overview of statistics used to model environmental data with many zeros (i.e., zero-inflated) or many values at the limit of detection (i.e., zero-altered). We will see how the approach can help determine what drivers or conditions determine whether the response variable is detected (above zero or above the limit of detection), and once detected, what factors determined its continued increase. The models can also incorporate spatial or temporal explanatory variables to determine if certain sites or timepoints are hotspots of change, and why.


For the course, we will go over an example dataset (predicting cyanotoxins across 1000 lakes from the continental US) and an R script to run a zero-altered model on this dataset. We will see how to interpret the model output and plot pertinent findings. Finally, the case study will showcase how zero-inflated and zero-altered modeling approaches can greatly improve our understanding of where and why contaminants occur across broad spatial and temporal scales, and ultimately increase the proportion of variance explained. Attendees are encouraged to bring their own laptops.

Presentation Guidelines

Please review the below guidelines prior to putting together your presentations.

Platform Instructions

You will be given a maximum of 15 minutes for each presentation, including time for questions. It is strongly recommended that you aim to present for 12 minutes, with 3 minutes for questions and for people to move among sessions. CEW session chairs are instructed to stick firmly to the time slots allotted so participants can take advantage of the various offerings at concurrent sessions.

Key Platform Guidelines

  • The aspect ratio of all projectors is 16 x 9.

  • The presentations should be a maximum of 12 min long.

Presenters will be required to save their PowerPoint presentations on the computer in their presenting room at least 20 min before their session begins. Session co-chairs may be in touch with further instructions.

Poster Instructions

Two full-day poster sessions are planned (Tuesday and Wednesday). Posters will be on display for the entire day and presenters will be able to discuss their posters with workshop delegates during refreshment breaks and at a daily late afternoon / early evening poster social. Authors have been assigned to a “Tuesday Poster Session” or a “Wednesday Poster Session” from 5 PM to 7:00 PM; authors should stand by their posters during the assigned times so that other workshop participants can discuss the presentation. Notwithstanding the author’s assigned time, all posters should be set up by 7 AM – 8 AM and taken down by 8 PM of the assigned presentation day.

Posters should be a maximum of 4 feet high by 8 feet wide as these are the dimensions of the poster boards. A common size for posters that fit the poster boards well are 3 feet high by 4 feet wide (i.e., 36“ x 48”). It is recommended that you bring business cards to hand out during poster sessions, paper-sized copies of your poster and/or place a QR code on the poster. Fabric poster panels and pins will be provided.  Each poster panel will be marked with the appropriate poster number; please put your poster up on the panel with the correct number assigned.

Key Poster Guidelines

  • Posters should be a maximum of 4 feet high by 8 feet wide (i.e., landscape orientation)
