This spring Ullrika organised as part of the Pufendorf theme EXPERT an online seminar about social science and risk communication. We used radon as a case. The seminar was attended by about 100 participants. The program with some of the presentations are found on the web page for the seminar
Bayes@Lund Book Club Spring 2021
This spring we will continue with the Bayes@Lund Book Club by continue reading Probability Theory: The logic of science by E.T. Jaynes, Cambridge University Press, 2003.
In 2020, we went through chapters 1-5. No we will continue with selected chapters from the book. We share some links to introductory videos by Aubrey Clayton and the text to the book.
Why this book is important (video introduction by Aubrey Clayton))
- March 1st and 29th Elementary Parameter Estimation (chapter 6) – text, video
- April 19th Sufficiency, Ancillarity, And All That (chapter 8) – text, video
- May 10th Repetitive Experiments – Probability and Frequency (chapter 9) – text, video
A session starts at 14.00 and lasts for about an hour

Riskförmiddag i Uppsala 2020
Den 3 december 2020 bjuder Riskkollegiet och Uppsala universitet in studenter, medlemmar och andra intresserade på några korta föredrag där forskare och myndigheter presenterar hur de i sin verksamheter arbetar med risk. Efter föredragen har vi en kort allmän diskussion där alla frågor och kommentarer är välkomna. Program som pdf: Riskförmiddag_Uppsala_Program

Hållbarhetsshowen har premiär
I samband med 2020 års ForskarFredag kommer streamas Hållbarhetsshowen den 28 november. Showen är ett resultat av ett samarbete mellan Ullrika Sahlin CEC och Stefan Zamudio, Vattenhallen. Det var lite svårt att göra en show av ett ganska allvarligt ämne. Vi ser fram emot att göra om den live i framtiden.
Showen visas på Youtube ca 2:12:00 in i den ca 3 timmar långa inspelningen från Forskarfredag.
Uncertainty and Bayesian Networks
‘This is what we don’t know’ ‐ Treating epistemic uncertainty in Bayesian networks for risk assessment is the title of a paper published in Integrated Environmental Assessment and Management by Ullrika Sahlin, Inari Helle and Dmytro Perepolkin.
https://doi.org/10.1002/ieam.4367
We explain parts of the paper in this talk that was held at the North America SETAC conference November 2020. Link to video
Bayes@Lund Book Club
Fall 2020 Bayes@Lund is organizing a book club on the foundational book Probability Theory: The logic of science by E.T. Jaynes
Why this book is important (video introduction by Aubrey Clayton)
Total of 3 sessions (~6 weeks)
- Session 1 (19 October 2020, 15:00)
Plausible Reasoning and The Quantitative Rules (chapters 1 and 2) – text, video1, video2 - Session 2 (09 November 2020, 15:00)
Elementary Sampling Theory (chapter 3) – text, video - Session 3 (23 November 2020 15:00)
Elementary Hypothesis Testing (chapter 4) – text, video1, video2
Participants are expected to read the respective chapter(s) in the book prior to the meeting. If you don’t get the chance to study the chapter, please, watch the video lecture. After the three sessions we will assess the interest to continue and may schedule another 3-5 sessions.
The Bayes@Lund Book Club (BLBC) sessions will consist of a 20-30 min lecture covering the material from the chapter(s) followed by a 30-40 min discussion.
Welcome

PhD course in interdisciplinarity Fall 2020
The content of the 2020 version of the PhD course Interdisciplinarity in Environmental Research has been decided. I wish I could take this course https://canvas.education.lu.se/courses/5152
Environmental models in waterfowl management under uncertainty
Introductory seminar
We are happy to announce the introductory seminar with PhD student Dmytro Perepolkin 
October 22nd 2020 10.15 – 12.00
Each PhD student in environmental science start their studies with preparing a literature review introducing their research topic. Dmytro’s paper can be found here bit.ly/dmi3kno-intropaper The seminar was recorded – ask Ullrika for a link.
The slides have now been published in the following repo: https://github.com/dmi3kno/LU-intropaper
Abstract
Environmental problems are characterized by high complexity, dynamism, stochasticity and interconnectedness of various ecological systems. This necessitates a holistic and systematic approach to environmental decision making, which addresses both stakeholder alignment (clarity of objectives), uncertainty related to management actions (what can and should be done) and lack-of-knowledge related to how systems will change and respond to these interventions (epistemic and aleatory uncertainty). We will provide a brief introduction into the subjects of Decision Analysis and Uncertainty Analysis and their applications in the environmental management. Then we introduce Adaptive Management as a framework for making recurring decisions in environmental domain and discuss the role of learning in resource management.
Waterfowl management problems require modeling of social, environmental and biological systems including animal populations, their interaction with natural landscapes and people. We will review statistical models commonly used in the three areas of waterfowl management: harvest, habitat, and human dimension, focusing on the explicit acknowledgement and treatment of uncertainty in these models.
Decision making under uncertainty
Decision making under uncertainty in relation to the pandemic was discussed by Åsa Knaggård in May 2020 (in Swedish).
A discussion about using probability to quantify uncertainty
On August 19th 2020 Ullrika moderated a discussion seminar about what it means to use precise probability to quantify epistemic uncertainty with applications on scientific assessments. This was a seminar in an online series at the Liverpool Institute for Risk and Uncertainty. https://riskinstitute.uk/riskinstituteonline/
A pdf of the presentation is available here
A recording of the three hour long seminar is on Youtube.
