Decision Making, Communication, and Risk: the Public Opinion Equation

SPEAKER:

Jean-Pierre Beaudoin

DATE/TIME:

FRI, 10/15/2021 - 3:00PM TO 4:00PM

LOCATION:

via Zoom

Fall 2021 Colloquium Series

Abstract:

What is a « good decision »? How is that judgment made? What role does « Public Opinon » play? All these questions refer to notions that vary with time, context and culture of the population concerned.

Who is the Public? Public opinion is a generational phenomenon. It takes on average 25 years for the underlying values of society to evolve and thus change the priorities of society and its expectations towards authorities of all natures.

What is Communication? The social practice of communication changes with the emergence of new devices. Yet, that is not the essence of change. More determining are the value attached by a society to Communication per se and what the term means, from information, to conversation, to debate : an issue for leadership.

What is Risk? The acceptance of risk, the hierarchy of threats and the time-span on which both notions are considered evolve with the generations and the living experience of accidents or catastrophes.

The proposal is to put the three terms in perspective and highlight key elements affecting governance and leadership issues, as the Public expects authorities to live up to the responsibilities which it assigns to them.

Abstract:

Electron beams are powerful tools for scientific and industrial applications. Owing to their short wavelength, electrons have seen broad use in advanced instrumentation, enabling X-ray generation, real-space imaging at sub-atomic scales, enhanced resolution in nano-fabrication, high precision mechanical machining and cancer treatment to name a few.

Recent advancements in technology have enabled the generation of densely packed, ultrashort pulses of electrons. Trains of femtosecond-long, relativistic beams can now be produced at MHz repetition rates in a compact room-sized setup, opening the doors to a plethora of new applications. Among others, Ultrafast electron diffraction (UED) has established itself as a leading technique to study non-equilibrium physical systems in solid, gas and liquid phases, providing a dynamic picture of atomic motion at femtosecond time-scales.

I will first cover recent work on scientific and technological developments in high-brightness electron beam generation and radiofrequency-based production and manipulation. I will then introduce the UED technique and discuss advancements in spatio-temporal resolution, with emphasis on the work performed at HiRES, the relativistic UED setup at LBNL.

Lecturer and Assistant Project Scientist in Nuclear Engineering

University of California, Berkeley

DATE/TIME:

FRI, 09/10/2021 - 3:00PM TO 4:00PM

LOCATION:

3105 ETCHEVERRY HALL

Fall 2021 Colloquium Series

Abstract:

The 2011 Fukushima Dai-ichi Nuclear Power Plant accident serves as an example of the risks associated with energy technologies and the need to minimize physical as well as psychological effects on local and global communities. We have established the RadWatch and DoseNet community outreach programs to enhance the public understanding of risks associated with radiation exposure. The RadWatch program works to provide transparent, relevant measurements of radioactivity in our environment through measurements of locally sourced fish and produce. The ongoing monitoring of radiation in our environment provides the public with a clear baseline for what is “normal”. This work has since been expanded to include the use of neutron activation analyses to determine the concentrations of heavy metals in such samples, further contextualizing previous radiological measurements and our environmental impact. Similarly, the DoseNet project was developed to bring radiation and environmental data into classrooms and connect directly with students. DoseNet is a network of radiation and environmental sensors connecting schools in the Bay Area, Japan, and around the world. The DoseNet program has used this network to recruit a handful of high school students each summer as interns. These programs represent parts of a multidisciplinary undertaking to educate the next generation about radiation science, improve scientific literacy, and improve our communication of technical concepts to our communities.

Fall 2021 Colloquium Series

Abstract:

The goal of radioanalytical chemistry is to identify and quantify radioisotopes present in a variety of samples. It combines advanced radiochemical separations with state-of-the art radiation detection techniques and provides information on the origin, speciation, and mobility of the material. It plays an important role in evaluating its impact on humans and the environment. The analysis of air, water, soil, and bioassay samples builds the foundation of operational environmental monitoring. However, the need for improved sample analysis methods became also apparent in the aftermath of the reactor accident at the Fukushima Nuclear Power Plant. The elevated salinity of sea and ocean water results in a complex matrix that hinders the isolation, characterization, and determination of the radioisotopes of interest. This presentation will discuss recent research aimed at developing analytical techniques for such challenging types of samples and give examples of their application.
