Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Â
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

2. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
THINK ABOUT IT
The DNA molecule must somehow specify how to assemble proteins,
which are needed to regulate the various functions of each cell.
What kind of structure could serve this purpose without varying from cell
to cell?
Understanding the structure of DNA has been the key to understanding
how genes work.
3. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Components of DNA
What are the chemical components of DNA?
4. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Components of DNA
What are the chemical components of DNA?
DNA is a nucleic acid made up of nucleotides joined into long strands or
chains by covalent bonds.
5. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Nucleic Acids and Nucleotides
Nucleic acids are long, slightly acidic molecules originally identified in
cell nuclei.
Nucleic acids are made up of nucleotides, linked together to form long
chains.
The nucleotides that make up DNA are shown.
6. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Nucleic Acids and Nucleotides
DNAâs nucleotides are made up of three basic components: a 5-carbon
sugar called deoxyribose, a phosphate group, and a nitrogenous base.
7. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Nitrogenous Bases and Covalent Bonds
The nucleotides in a strand of DNA are joined by covalent bonds formed
between their sugar and phosphate groups.
8. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Nitrogenous Bases and Covalent Bonds
DNA has four kinds of nitrogenous bases: adenine (A), guanine (G),
cytosine (C), and thymine (T).
The nitrogenous bases stick out sideways from the nucleotide chain.
9. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Nitrogenous Bases and Covalent Bonds
The nucleotides can be joined together in any order, meaning that any
sequence of bases is possible.

11. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Solving the Structure of DNA
What clues helped scientists solve the structure of DNA?
The clues in Franklinâs X-ray pattern enabled Watson and Crick to build a
model that explained the specific structure and properties of DNA.
12. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Chargaffâs Rules
Erwin Chargaff discovered that the percentages of adenine [A] and
thymine [T] bases are almost equal in any sample of DNA.
The same thing is true for the other two nucleotides, guanine [G] and
cytosine [C].
The observation that [A] = [T] and [G] = [C] became known as one of
âChargaffâs rules.â
13. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Franklinâs X-Rays
In the 1950s, British scientist Rosalind Franklin used a technique called
X-ray diffraction to get information about the structure of the DNA
molecule.
14. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Franklinâs X-Rays
X-ray diffraction revealed an X-shaped pattern showing that the strands
in DNA are twisted around each other like the coils of a spring.
The angle of the X-shaped pattern suggested that there are two strands
in the structure.
Other clues suggest that the nitrogenous bases are near the center of
the DNA molecule.
15. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Work of Watson and Crick
At the same time, James Watson, an American biologist, and Francis
Crick, a British physicist, were also trying to understand the structure of
DNA.
They built three-dimensional models of the molecule.
16. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Work of Watson and Crick
Early in 1953, Watson was shown a copy of Franklinâs X-ray pattern.
The clues in Franklinâs X-ray pattern enabled Watson and Crick to build
a model that explained the specific structure and properties of DNA.
17. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Work of Watson and Crick
Watson and Crickâs breakthrough model of DNA was a double helix, in
which two strands were wound around each other.

The Double-Helix Model
What does the double-helix model tell us about DNA?
19. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Double-Helix Model
What does the double-helix model tell us about DNA?
The double-helix model explains Chargaffâs rule of base pairing and how
the two strands of DNA are held together.
20. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
The Double-Helix Model
A double helix looks like a twisted ladder.
In the double-helix model of DNA, the two strands twist around each
other like spiral staircases.
The double helix accounted for Franklinâs X-ray pattern and explains
Chargaffâs rule of base pairing and how the two strands of DNA are held
together.
21. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Antiparallel Strands
In the double-helix model, the two strands of DNA are âantiparallelââ
they run in opposite directions.
This arrangement enables the nitrogenous bases on both strands to
come into contact at the center of the molecule.
It also allows each strand of the double helix to carry a sequence of
nucleotides, arranged almost like letters in a four-letter alphabet.
22. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Hydrogen Bonding
Watson and Crick discovered
that hydrogen bonds could
form between certain
nitrogenous bases, providing
just enough force to hold the
two DNA strands together.
Hydrogen bonds are relatively
weak chemical forces that
allow the two strands of the
helix to separate.
The ability of the two strands
to separate is critical to DNAâs
functions.
23. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Base Pairing
Watson and Crickâs model
showed that hydrogen bonds
could create a nearly perfect fit
between nitrogenous bases
along the center of the molecule.
These bonds would form only
between certain base pairsâ
adenine with thymine, and
guanine with cytosine.
This nearly perfect fit between
AâT and GâC nucleotides is
known as base pairing, and is
illustrated in the figure.
24. Lesson OverviewLesson Overview The Structure of DNAThe Structure of DNA
Base Pairing
Watson and Crick realized that
base pairing explained Chargaffâs
rule. It gave a reason why [A] =
[T] and [G] = [C].
For every adenine in a double-
stranded DNA molecule, there
had to be exactly one thymine.
For each cytosine, there was one
guanine.
