« Mon travail représente une forme d’action participative ». Entretien avec Ai Xiaoming
No full textAi Xiaoming, née à Wuhan en 1953, est professeure retraitée du Département de littérature de l’Université Sun Yat-Sen de Canton. Après une carrière universitaire en littérature comparée, elle se distingue en tant qu’intellectuelle engagée en s’impliquant dans un premier temps dans la défense des droits des femmes et des homosexuels. Elle organise alors de nombreuses actions ayant pour but de sensibiliser à la discrimination et à la violence exercée à l’égard des femmes, dont la plus célèbre est la traduction et la mise en scène, avec ses étudiants, des Monologues du vagin. Utilisé tout d’abord comme un outil visant à enregistrer et diffuser ces activités dans un cadre purement pédagogique, la vidéo devient rapidement, pour Ai Xiaoming le moyen de rendre compte des cas de violation des droits des citoyens par les institutions publiques en Chine. Ces dernières années, elle a constitué un corpus d’une dizaine de documentaires indépendants abordant des sujets tels que l’élection des comités de village, le droit de propriété des terres, le VIH/ SIDA, et le scandale qui a suivi le tremblement de terre du Sichuan.

Quantitative Explainable AI For Face Recognition
No full textFace recognition is widely adopted in our daily life in recent years. It usually relies on sophisticated techniques to achieve high accuracy in identifying or verifying the identities of given face images. Artificial intelligence (AI), especially deep learning, is a popular technique used in face recognition due to its high accuracy, known as the deep face recognition. However, the reliability of the deep face recognition models becomes a concern, especially in security-critical applications. The main challenge is the "black-box" nature of the sophisticated internal structure of the models. Explainable AI has emerged as a solution that provides meaningful explanations to help humans understand the complicated internal structure of the deep learning models, and increase the transparency and interpretability of the "black box". However, this is often at the cost of model accuracy. In this paper, we propose an approach to increasing both the accuracy and interpretation of quantitatively explainable AI models for face recognition. It increases the accuracy of the explainable face recognition models by applying improved loss functions and enhances quantitative interpretability by adding a new visualisation feature. The proposed approach is validated using advanced deep face recognition models and is compared with existing approaches to demonstrate its better performance.No Full Tex
Comparison between a phenomenological approach and a morphoelasticity approach regarding the displacement of extracellular matrix
No full textPlastic (permanent) deformations were earlier, modeled by a phenomenological model in Peng and Vermolen (Biomech Model Mechanobiol 19(6):2525–2551, 2020). In this manusctipt, we consider a more physics-based formulation that is based on morphoelasticity. We firstly introduce the morphoelasticity approach and investigate the impact of various input variables on the output parameters by sensitivity analysis. A comparison of both model formulations shows that both models give similar computational results. Furthermore, we carry out Monte Carlo simulations of the skin contraction model containing the morphoelasticity approach. Most statistical correlations from the two models are similar, however, the impact of the collagen density on the severeness of contraction is larger for the morphoelasticity model than for the phenomenological model.Numerical Analysi

DesignPrompt: Using Multimodal Interaction for Design Exploration with Generative AI
No full textInternational audienceVisually oriented designers often struggle to create effective generative AI (GenAI) prompts. A preliminary study identified specific issues in composing and fine-tuning prompts, as well as needs in accurately translating intentions into rich input. We developed DesignPrompt, a moodboard tool that lets designers combine multiple modalities — images, color, text — into a single GenAI prompt and tweak the results. We ran a comparative structured observation study with 12 professional designers to better understand their intent expression, expectation alignment and transparency perception using DesignPrompt and text input GenAI. We found that multimodal prompt input encouraged designers to explore and express themselves more effectively. Designer’s interaction preferences change according to their overall sense of control over the GenAI and whether they are seeking inspiration or a specific image. Designers developed innovative uses of DesignPrompt, including developing elaborate multimodal prompts and creating a multimodal prompt pattern to maximize novelty while ensuring consistency
[[alternative]]The study of the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu
No full text[[abstract]]The main purpose of this study were to explore the relations between the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu. The researcher applied the questionnaire of “the ocean sport’s attraction, service quality and behavioral consequences in Peng-hu “ and I drew 500 visitors as the research samples who participated in ocean sports in Peng-hu during August and September in 2005. The data collected from valid questionnaires were analyzed by descriptive statistics, Pearson’s product moment correlation, stepwise multiple regression analysis and canonical correlation analysis. The results are as followed:
1. The ocean sports in Peng-hu attracted visitors to a certain degree and the whole service quality is comfortable to them.
2. The relationship between the ocean sport’s attraction and service quality in Peng-hu was positive to a certain degree, and the higher service quality is, the greater ocean sport’s attraction in Peng-hu is.
3. Within each factors of the ocean sport’s attraction and the service quality, “the specialty of designing activity “and “the comfort of the environment “ had the best prediction to the loyalty of behavioral consequences; “advertisement and spread of the main activity” and “personal requirement” explain “better than any other factors.
4. The canonical correlation analysis of the study was the ocean sport’s attraction and service quality in Peng-hu have a high and positive correlation with the loyalty of behavioral consequences; the ocean sport’s attraction in Peng-hu has a moderate and positive correlation with the tendency of complaint of behavioral consequences.
Based on the results, we suggest the related organizations should:（1）strengthen the diversity of activity and develop package route of travel;（2）enforce the communication of information and promote the quality of complementary service;（3）integrate the resources and set up conservation area to build the continuous managing mold of ocean sport’s tourism.
For further research in the future: incorporate the follow-up issue of ocean sport’s tourism with profound interview and pay equal attention to qualitative research and quantitative research. Extending the subjects to related organization administrators、managers and dealers、local people and foreign tourist etc. and proceeding a comprehensive research.
