0253 - Teaching Analytics Visually with Stefan Helfrich
Hosted by Christina Philips and Anabela Da Silva Filipe Soares.
Welcome to today’s seminar by Stefan Helfrich.
In this session Stefan talks about the education paths on offer for data analytics and the need for balance between learning concepts versus hands-on experiences with tools. Stefan makes the case for the value of visual workflow approaches for teaching and implementing analytics.
How do we do that? KNIME implements a well-documented, comprehensive and capable software environment that enables users to design and operate data analytics workflows visually using the following objects:
· Nodes perform tasks on data. Nodes have inputs and outputs. Nodes have status/indicators. Nodes are natively implemented in Java. Python scripts may also be used as code nodes.
· Connectors link nodes. Connectors indicate data flows. Connectors send data from one node to another. Connectors have direction. Nodes plus connectors enable you to create workflows.
· Workflows are designed aggregates of nodes linked using connectors
· Components/Metanodes encapsulate discrete sub-workflows. Component/metanodes can be used like nodes.
· A large library of pre-build nodes and metanodes are offered for common tasks like cleaning up data, visualization, plug into Tableau and PowerBI.
· Supports all types of data.

263. 0263 - Learning from the London Whale with Denis McCarthy
37:06||Season 13, Ep. 263Welcome to the Economics and Finance class.Our hosts are Daksh Wadhwa and Peter Barrett. Today, we are very pleased to welcome Denis McCarthy, Head of Financial Risk Model Development at AIB.Thank you for coming in to speak to us today. Can you tell us a little about yourself and your journey into financial risk modelling?· What does a day in the week look like on your team? [for a finance/economist, quant analyst, programmer]· How can a large organisation manage end-user tools like Excel? [policy, practices, systems management…]· Much of the focus is on the technical characteristics and the actions of individuals but not so much on organisational cultural. How can we address the organisational culture angle? [for example, grow and protect a culture of dissent? What might that look like?]· What about review processes and how to avoid undue influence from one or other actors? [maybe relate to audit trails, version control]· Are our models becoming too complex? [to either understand fully or to apply in a timely manner? What kinds of new systemic risk do you think about?]· Is sentiment analysis applied much to risk measurement? [how to do it? gotchas and the dark art of automated textual analysis for gauging sentiment from company filings, conference call transcripts and other bulk sources]Questions from the audience?Before we finish, is there anything further you'd like to add?Thank you so much for your time and for sharing your thoughts with us today.

259. 0259 - Making New Money with Quinn DuPont
01:10:36||Season 13, Ep. 259Welcome to the CITO Podcast.This episode is a seminar by Quinn DuPont titled “Making New Money: How autonomous communities produce and govern cryptocurrencies.” Paul Dylan-Ennis opens the session with a brief introduction after which Quinn presents an overview of his project, and Donncha Kavanagh makes some observations and invites reactions.Decentralized cryptocurrencies are upending the foundations of economic power, challenging centuries of state and bank control over money. This research critically examines the rise of digital wildcat banking and its profound implications for economic sovereignty. Leveraging digital forensics, data science, and OSINT, this work reveals who actually produces and governs cryptocurrencies—and how their collective labor reshapes value and risk. It explores the forces behind decentralized money, the vulnerabilities these systems introduce, and the future role of state-issued currencies in an era of rapid monetary transformation.Reflecting on the project Quinn notes:"I've been working on this for well over a year now, and while it is still in development, the basic outline is complete. I make some pretty provocative claims, like arguing that global forces first emerging in the 1970s lead us inexorably to this point where the labour required to produce and govern new money has become involuted[1]. It’s a unique project that reveals how new money is made and details the implications for banks, nation states, and society. I also have some fun stories to share, like my effort to vampire attack Trump's WLFI token or my reverse engineering of the FBI's Operation Token Mirrors."[1] Involution; the theory from Clifford Geertz where, in the original context, rice production becomes internally competitive and the processes require more labour without an increase in output - analogous to this story of technological development and precarious technological labour. I argue that the operational infrastructure of crypto expands to require more labour, despite no correlated increase in output. Thus, crypto overtakes national currencies not by meeting a market demand, but by accommodating excess labour supply.Notes, extra questions, and further reading:Quinn’s homepage - https://iqdupont.comChina’s “Involuted” Generation by Yi-Ling Lu | The New Yorker Published MAY 14The president and the billion-dollar crypto businesses – How the Trump companies made $1bn from crypto by Joe Miller and Alex Rogers in Washington, Paul Caruana Galizia, Nikou Asgari, Eade Hemingway, Oliver Hawkins and Chris Cook in London | FT.com Published OCT 16 2025"Overcapacity" or "involution"?

255. 0255 - Learning in the Digital Classroom
25:26||Season 13, Ep. 255Welcome to Design Talk. This episode resurrects a recording from the College of Business Intercultural Forum bite-sized workshop series, session 7. A conversation with Jacob Eisenberg and Allen Higgins on “adapting experiential learning to the digital classroom”. The talk was hosted by Kathleen O’Reilly and Linda Yang.Key takeaways:Students benefit from being in control of at least some of the settings within which learning experiences unfold so, consider using multiple apps rather than integrated systems, for example, separate the video presence experience (e.g. Zoom or Teams) from the digital whiteboard from the shared document.We should encourage experimentation with tools, old and new alike.Experiment with multiple means of engagement like polls, MCQs, discussion boards but feel free to drop a tool if you feel it doesn’t work well.Always be seeking copious feedback from learners all the time. The difficulties or challenges they encounter may be intrinsic to the learning process rather than problems to solve but just knowing where they are in the learning process is valuable; for example, are they stuck, is there a shared misunderstanding or misconception, or knowing who has made progress so they might act as a catalyst for the wider group.Use breakout rooms tactically to scale up and scale down groups to sizes appropriate to the activity.AcknowledgementsMusic Title: Monologue Lu-Fugi octave climb with extra notes with wa wa with other tweaksArtist: Allen HigginsSource: introoutroLicense: CC BY-NC-SA 4.0 License note: Includes derivative work from KORG Monologue/Sound presets by KORG Inc. permitted under Terms of Use (https://korg.shop/terms-of-use) Section 2: “Derivative works and their authors benefit in turn from the full protection of copyright without prejudicing the rights of the original work's author”.Cover Art Title: Complex collageArtist: Allen HigginsSource: vignette_version.pptxLicense: CC BY-NC-SA 4.0Podcast LicenseDesign Talk (dot IE) CC BY-NC-SA 4.0 The license can be viewed at https://creativecommons.org/licenses/by-nc-sa/4.0By taking part you give permission for your voice to be recorded, for the recording to be edited, and for it to be posted and published as a podcast.AcknowledgementsMusic Title: Monologue Lu-Fugi octave climb with extra notes with wa wa with other tweaksArtist: Allen HigginsSource: introoutroLicense: CC BY-NC-SA 4.0 License note: Includes derivative work from KORG Monologue/Sound presets by KORG Inc. permitted under Terms of Use (https://korg.shop/terms-of-use) Section 2: “Derivative works and their authors benefit in turn from the full protection of copyright without prejudicing the rights of the original work's author”.Cover Art Title: Complex collageArtist: Allen HigginsSource: vignette_version.pptxLicense: CC BY-NC-SA 4.0Podcast LicenseDesign Talk (dot IE) CC BY-NC-SA 4.0 The license can be viewed at https://creativecommons.org/licenses/by-nc-sa/4.0By taking part, you give permission for your voice to be recorded, for the recording to be edited, and for it to be posted and published as a podcast.
