Fine-Tuning Large Language Models for Codebook-Guided Coding of Students' Mathematics Metaphor Responses

Abstract: Student-generated metaphors about mathematics can reveal students' attitudes, beliefs, identities, and experiences, but human expert coding of these thematically and semantically complex open-ended responses is time-intensive and difficult to scale. This study examines whether LoRA-based supervised fine-tuning of large language models (LLMs) can improve their performance on codebook-guided coding tasks for student mathematics metaphors. We used a human-coded corpus of 2,265 Grade 6-8 responses to food- and animal-based metaphor prompts and instructed the LLMs to perform two coding tasks: valence-intensity coding to capture the direction and strength of students' affective orientations toward mathematics, and thematic coding to capture students' framings of mathematics as expressed through their metaphors. We compared two proprietary models, GPT-4o mini and GPT-5 mini, under prompt-only conditions with two open-weight models, DeepSeek-R1 1.5B and Mistral 7B, evaluated before and after fine-tuning. Results show that fine-tuning substantially improved the performance and run-to-run reliability of the open-weight models across both tasks relative to their base versions. The fine-tuned compact open-weight models became competitive with, and often outperformed, the proprietary prompt-only models. These findings suggest that compact open-weight LLMs can support scalable, locally controllable, and privacy-conscious AI-assisted measurement of students' metaphor responses in mathematics education.

Today, I've heard the third instance of a project losing a valuable contributor because the university that had the budget and intention to hire them had a contract (or extension) planned, and all of a sudden there are uncommunicated problems, the contract would start months later, leaving the contributor unemployed for a months-long gap. Again in this case, the contributor switched to more reliable employer in industry.

Revisiting Safe Temperature for Environmental Accelerated Aging of Additively Manufactured Polymers

Abstract: Accelerated aging is widely used to study the long-term behavior of materials within laboratory time scales, particularly for materials exposed to solvent environments over extended periods. This is especially important for additively manufactured (AM) polymers, whose increasing use in naval and commercial undersea applications requires reliable methodologies for assessing durability under in-service conditions. A common approach relies on elevating the temperature below the glass transition or melting temperature to accelerate degradation. However, the temperature limits for accelerated aging of AM polymers remain poorly understood, particularly because temperatures beyond a threshold may activate deformation and degradation mechanisms that are absent under service conditions. To address this gap, this paper investigates fused deposition modeling (FDM) Acrylonitrile Butadiene Styrene (ABS) exposed to saltwater and deionized (DI) water to establish a temperature threshold for accelerated aging in aqueous environments and propose a methodology for determining such thresholds. Controlled geometries and varying print directions were employed to explicitly probe the underlying mechanisms. We show that samples exposed to temperatures above the threshold exhibit pronounced shrinkage and warping along the printing direction due to the relaxation of process-induced internal stresses. These observations establish an accelerated-aging temperature threshold of 50$^\circ$C for ABS, beyond which additional mechanisms absent under service conditions become active. Additionally, the resulting geometric distortions are masked in thick geometries but become highly pronounced in thin structures. Moreover, solvent ionic content strongly influences water uptake, with saltwater reaching saturation in 1 day, whereas DI water did not reach saturation even after 30 days and exhibited greater mass uptake.

Here is the transcript of the meat of Carney’s proposal for a deeper Canada and EU partnership in text. Full text of the speech at the second link. The 2 minute video clip got a chuckle (“better manners”).
“So let me say plainly what Canada proposes.
Canada and Europe should secure our strategic autonomy through deep cooperation in the full range of strategic capabilities, including critical minerals, defence industrial capacity, AI and compute, energy security, space, and payments.
We should move toward seamless, digital trade in non-agricultural goods and a wide range of services.
We should deepen our people-to-people ties, allowing our youth to live, work and study where they want on either side of the Atlantic.
Canadian membership of Erasmus can give your students, and ours, more opportunity to learn at some of the world’s top universities, to broaden their horizons, and to build lasting ties that will sustain our alliance for the future.
Canadian membership of the next generation of Horizon would allow us to pool resources, cooperate on frontier technologies, and leverage our world-class research institutes and universities.
Yesterday, President von der Leyen announced a “new European Corporation on Critical Raw Materials” to obtain and stockpile the material needed for electric cars, chips and batteries, clean technology, and defence. Canada has deposits of over 34 critical minerals, and we are among the top producers of the 10 most essential for the world’s energy transition. Our alliance can help fill Europe’s need for reliable supply, Canada’s need for advanced processing capabilities, and our common objective to build complete value chains.
Canada can contribute LNG and hydrogen at large scale to support Europe’s energy security including by developing and leveraging new port infrastructure in the High North and on our East Coast. We, in turn, can benefit from your leadership in many clean energy technologies.
We can pool new sovereign compute capacity and build more secure broadband connections between Europe and Asia via our common geography.
Canada and Europe can join forces to develop AI safety protocols, coordinate common standards, and strengthen transparency, all while developing applications so our governments and companies can serve our citizens better.
Canada and Europe should also consider exploring an integrated market for financial services to broaden choice and reduce costs for our citizens, improve access to capital for our companies while maintaining our world-leading financial resilience.”

RE: infosec.exchange/@metacurity/1
So I've been breaking down this memo for the past hour or so, and there is a part of it, Section 4(c), that determines whether a target is eligible for private companies to conduct operations against foreign cyber-enabled transnational criminal organizations.
Section 4(c) says a foreign group is presumed to be a non-state actor unless the government already possesses "clear intelligence" proving otherwise.
For clear, independent criminal gangs such as Scattered Spider, this makes sense.
But for criminal gangs in Russia, China, Iran, and North Korea, where criminal actors are staffed alongside a hostile state's security services, the presumption is least reliable and could result in inadvertent escalation to global geopolitical levels, no?
In other words, the real risk isn't a participating company hitting the wrong criminal server — it's hitting infrastructure with an undisclosed link to a hostile intelligence service and turning a law-enforcement operation into a state-to-state incident.
