La representación de la variación fonética en lenguas pluricéntricas. una aproximación integral
Adaptive speech technologies offer a vehicle for representing pluricentric language variation and the description of both dominant and non-dominant speech varieties. In this article, the work of the LUPo project is described for modeling phonetic variation across national and sub-national varieties of the Portuguese language. While the motivation for this research is based around the development of highquality pronunciation lexica for a Portuguese text-to-speech system – a goal which, itself, is aimed at facilitating the entry of lesser or undocumented variants into the digital domain – the repercussions for pluricentricity are far reaching. We describe how systems such as LUPo can be used to model variation across phonetically similar and disparate national, sub-national, and sociolectal varieties, as well as
presenting linguists with a means of testing and observing notions of linguistic distance in terms of shared
or innovative rules and phonetic features, and for evaluating the pulling effect of different linguistic centers.Las tecnologÃas de adaptación del habla ofrecen un vehÃculo para representar la variación lingüÃstica pluricéntrica y la descripción de variedades de habla dominantes y no dominantes. En este artÃculo, se describe el trabajo que lleva a cabo el proyecto LUPo para la representación de la variación fonética en las variedades nacionales y subnacionales del portugués. Mientras que la motivación para esta investigación se basa en el desarrollo de léxicos de pronunciación de alta calidad para un sistema de texto a voz del portugués − un objetivo que, en sà mismo, tiene por objeto facilitar la entrada en el dominio digital de las variantes menores o indocumentadas − las repercusiones para pluricentricidad son de largo alcance. Describimos cómo una sistema como LUPo pueden representar la variación a través variedades
nacionales, subnacionales y sociolectales fonéticamente similares y diferentes, de la misma manera que los lingüistas pueden utilizarlo con un medio de prueba y observación de las nociones de distancia lingüÃstica en términos de reglas compartidas o innovadoras y de rasgos fonéticos, y para evaluar el efecto de extracción de los diferentes centros de lingüÃstica
Articulating (Uncertain) AI Futures of Artistic Practice:A Speculative Design and Manifesto Sprint Approach
AI is rapidly becoming enmeshed in our professional and private lives. The ubiquity of such technologies raises a host of ethical questions, value clashes, and unforeseen consequences that must be confronted. Developments such as Ai-Da and DALL-E 2 are exciting in that they present robust new capabilities in AI and creativity. However, the futures such technologies unlock are also unpredictable. Given the speed with which such technologies are emerging and becoming adopted, the need to engage target audiences to weigh in on possible AI futures is critical. Our pilot project, Artistic Process Futures and AI, seeks to explore the role and potential implications of AI technologies with artists. In this paper, we show how participatory speculative design processes might be channeled into a public statement, or manifesto, regarding possible and preferable AI futures for supporting the artistic process, and how our workshop exposed uncertainty at the core of such deliberation
Too bad: ChatGPT writes your emails, but it's not Ron Blauw
Kunstmatige Intelligentie speelt een steeds grotere rol in creatieve expressie. ChatGPT en DALL-E genereren binnen seconden teksten, beelden en meer. Dit kan geweldig helpen om creatief werk naar een hoger niveau te tillen, maar er zit ook een keerzijde aan deze innovaties. Creatieve professionals uiten hun zorgen over auteursrecht en de structurele bias en fouten in deze software. We staan daarom op een kruispunt. Accepteren we passief onze groter wordende afhankelijkheid van deze technologie? Of stellen we de nodige maar moeilijke vragen over de sociale, politieke, morele en praktische implicaties van kunstmatige intelligentie en gaan we over tot actie

Cultural probes for environmental education:Designing learning materials to engage children and teenagers with local biodiversity
Direct contact with nature is paramount in deepening children’s and teenagers’ interest in biodiversity. Learning materials chosen to convey information and engage participants during outings in nature-rich environments are varied and can support rich learning experiences. For this purpose, learning materials can be acquired "off-the-shelf" or developed for site-specific locations or projects. However, there is little guidance on potential techniques for those wishing to generate contextually relevant materials. With the view of responding to this challenge, we propose the cultural probes technique. We demonstrate that the technique, commonly used in qualitative research to generate novel insights in conversation with participants, can instigate innovative and thoughtful approaches to materials designed for children and teenagers to explore nature. We present a toolkit that draws on the literature on cultural probes, inquiry-based learning, and the value of sensory, emotional, and aesthetic experiences in environmental education for structuring interactions with participants. To test our approach, we applied a descriptive research design and mixed-methods approach for collecting questions from youths between the ages of 10 and 18, inspired by a nature walk and a set of exploratory tasks executed through the toolkit. Specifically, we tested our toolkit along a trail in the Nature Park of Terceira, situated in the Azores, a Portuguese volcanic archipelago in the North Atlantic. Here, we present and reflect on the data collected during one visit organized over two days with two groups of participants and one post-trail activity directed at both groups. Results demonstrate that the open-ended and playful nature of cultural probes offers a novel way to engage youths with nature-rich environments through questioning. This contribution further highlights the potential of cultural probes for instigating encounters that tap into the value of sensory, emotional, and aesthetic experience in nature, with positive outcomes for participants
Quantifying the Topology of Magnetic Skyrmions in three Dimensions
Magnetic skyrmions have so far been treated as two-dimensional spin
structures characterized by a topological winding number describing the
rotation of spins across the skyrmion. However, in real systems with a finite
thickness of the material being larger than the magnetic exchange length, the
skyrmion spin texture extends into the third dimension and cannot be assumed as
homogeneous. Using soft x-ray laminography we reconstruct with about 20nm
spatial (voxel) resolution the full three-dimensional spin texture of a
skyrmion in an 800 nm diameter and 95 nm thin disk patterned into a trilayer
[Ir/Co/Pt] thin film structure. A quantitative analysis finds that the
evolution of the radial profile of the topological skyrmion number and the
chirality is non-uniform across the thickness of the disk. Estimates of local
micromagnetic energy densities suggest that the changes in topological profile
are related to non-uniform competing energetic interactions. Theoretical
calculations and micromagnetic simulations are consistent with the experimental
findings. Our results provide the foundation for nanoscale magnetic metrology
for future tailored spintronics devices using topology as a design parameter,
and have the potential to reverse-engineer a spin Hamiltonian from macroscopic
data, tying theory more closely to experiment.Comment: 18 pages, 4 figure
The Field Guide app:Connecting island communities to local conservation through mobile interaction
C&T'21: 10th International Conference on Communities & Technologies: Wicked Problems in the Age of Tech - Seattle, United States, June 20–25, 2021.Here we present Field Guide, a mobile application (app) designed to connect communities to nature-rich environments, which play a crucial role in nature conservation efforts. The app aligns to a mode of science communication that seeks to establish direct contact between publics and specialised scientific communities, most commonly known as the ’ask a scientist’ approach. Field Guide uses a geolocation positioning system to offer users the opportunity to pose questions to scientists whilst exploring a nature conservation site. In this demo, we display the app as a mock-up presentation before its first use by children and teenagers during afield-trip to a nature trail later in 2021.The Field Guide project is funded by The Foundation for Science and Technology (FCT), Portugal, grant number PTDC/CEDEDG/31182/2017; IRA was funded by national funds through FCT – Fundação para a Ciência e a Tecnologia, I.P., under the Norma Transitória – DL57/2016/CP1375/CT0003.info:eu-repo/semantics/publishedVersio
