    Mobile heritage practices. Implications for scholarly research, user experience design, and evaluation methods using mobile apps.

    Get PDF
    Mobile heritage apps have become one of the most popular means for audience engagement and curation of museum collections and heritage contexts. This raises practical and ethical questions for both researchers and practitioners, such as: what kind of audience engagement can be built using mobile apps? what are the current approaches? how can audience engagement with these experience be evaluated? how can those experiences be made more resilient, and in turn sustainable? In this thesis I explore experience design scholarships together with personal professional insights to analyse digital heritage practices with a view to accelerating thinking about and critique of mobile apps in particular. As a result, the chapters that follow here look at the evolution of digital heritage practices, examining the cultural, societal, and technological contexts in which mobile heritage apps are developed by the creative media industry, the academic institutions, and how these forces are shaping the user experience design methods. Drawing from studies in digital (critical) heritage, Human-Computer Interaction (HCI), and design thinking, this thesis provides a critical analysis of the development and use of mobile practices for the heritage. Furthermore, through an empirical and embedded approach to research, the thesis also presents auto-ethnographic case studies in order to show evidence that mobile experiences conceptualised by more organic design approaches, can result in more resilient and sustainable heritage practices. By doing so, this thesis encourages a renewed understanding of the pivotal role of these practices in the broader sociocultural, political and environmental changes.AHRC REAC

    E-learning usage from a social constructivist learning approach: perspectives of Iraqi Kurdistan students in social studies classrooms

    Get PDF
    Background: Many schools in the Iraqi Kurdistan Region have incorporated information and communication technologies (ICT) into their environments. However, the results have shown that computer usage has had only a minimal effect on the classroom environment and learning outcomes. This minimal effect could be attributed to the teaching and learning of social studies subjects, which often rely on a traditional vision of teaching and an excessive inclusion of facts and dates in school textbooks. Consequently, students feel compelled to memorize all the information to pass tests. Yet, merely employing technology alongside traditional teaching and assessment approaches, such as lecturing or having students study in isolation without any form of collaborative learning, does not foster the development of students' higher-order thinking skills. It's time to revitalize school curricula and teaching practices to embrace a more contemporary, open-minded approach to social science education. This approach should incorporate a social constructivist perspective with technology to better instill international moral values such as democracy, respect for differences, and learning to live harmoniously with others. Aim: This cross-sectional study aims to investigate the impact of a social constructivist learning approach on the acceptance of technology and its influence on perceived e-learning outcomes among students in the Iraqi Kurdistan Region. Additionally, this study examines the differences in the effects of the social constructivist learning approach and dimensions of technology acceptance on perceived e-learning outcomes between students studying social studies in Arabic and those studying social studies in English. Setting and participants: Data were gathered from both public and private schools in Erbil governorate, situated in northern Iraq and affiliated with the Ministry of Education-Iraqi Kurdistan Regional Government. To select participants, a random sampling technique was employed, encompassing students in grades 8 through 12 of both genders. The data were obtained through a self-administered paper-based questionnaire. Instruments: Data were collected using a social constructivist learning environment survey (personal relevance, critical voice, shared control, uncertainty, student negotiation), dimensions of the attitude toward technology (attitude toward technology use, perceived usefulness, feeling ease of use, learning facility condition, and subjective norms), some additional external variables (investigation, respect for difference, student economic ability, and perceived e-learning outcomes), and socio-demographic data. Conclusion: This study is intended to emphasize the significance of employing constructivist pedagogy to enhance the technology acceptance model and improve learning outcomes. The findings of the study showed that a social constructivist learning environment had a favorable influence on perceived e-learning outcomes as well as ease of use, perceived usefulness, investigation, and respect for difference. Attitude towards technology use and perceived usefulness are contributory factors to the positive perceived e-learning outcomes. Furthermore, feeling ease of use technology has a positive effect on both attitude towards technology use and perceived usefulness. Perceived usefulness also has a direct positive impact on attitudes towards technology use. Finally, students’ technological experience is positively correlated with feeling ease of use but not with perceived usefulness. Additionally, regarding the comparison between students studying social studies in Arabic and those in English, the findings demonstrated that students studying social studies in English showed stronger positive effects from the social constructivist learning environment on their perceived e-learning outcomes. Conversely, students studying social studies in Arabic demonstrated a more potent positive effect of perceived usefulness on their attitudes towards technology. Moreover, the positive impact of an attitude towards technology use on perceived e-learning outcomes was more pronounced among the Arabic students compared to their English counterparts. Additionally, the influence of the learning facility on the perceived ease of use, as well as the perceived usefulness of technology, differed between the two groups. The English group experienced a more substantial positive impact. However, there was no significant difference observed in the effect of feeling ease of use on attitudes towards technology use between the English and Arabic student groups. Furthermore, no significant difference was observed in the effect of perceived usefulness on the social constructivist learning environment for either group. The findings from this research are expected to contribute to the development of effective and efficient counseling and support intervention programs. These programs can play a crucial role in transforming teachers

    Resource-aware scheduling for 2D/3D multi-/many-core processor-memory systems

    Get PDF
    This dissertation addresses the complexities of 2D/3D multi-/many-core processor-memory systems, focusing on two key areas: enhancing timing predictability in real-time multi-core processors and optimizing performance within thermal constraints. The integration of an increasing number of transistors into compact chip designs, while boosting computational capacity, presents challenges in resource contention and thermal management. The first part of the thesis improves timing predictability. We enhance shared cache interference analysis for set-associative caches, advancing the calculation of Worst-Case Execution Time (WCET). This development enables accurate assessment of cache interference and the effectiveness of partitioned schedulers in real-world scenarios. We introduce TCPS, a novel task and cache-aware partitioned scheduler that optimizes cache partitioning based on task-specific WCET sensitivity, leading to improved schedulability and predictability. Our research explores various cache and scheduling configurations, providing insights into their performance trade-offs. The second part focuses on thermal management in 2D/3D many-core systems. Recognizing the limitations of Dynamic Voltage and Frequency Scaling (DVFS) in S-NUCA many-core processors, we propose synchronous thread migrations as a thermal management strategy. This approach culminates in the HotPotato scheduler, which balances performance and thermal safety. We also introduce 3D-TTP, a transient temperature-aware power budgeting strategy for 3D-stacked systems, reducing the need for Dynamic Thermal Management (DTM) activation. Finally, we present 3QUTM, a novel method for 3D-stacked systems that combines core DVFS and memory bank Low Power Modes with a learning algorithm, optimizing response times within thermal limits. This research contributes significantly to enhancing performance and thermal management in advanced processor-memory systems

    Connecting the Dots in Trustworthy Artificial Intelligence: From AI Principles, Ethics, and Key Requirements to Responsible AI Systems and Regulation

    Full text link
    Trustworthy Artificial Intelligence (AI) is based on seven technical requirements sustained over three main pillars that should be met throughout the system's entire life cycle: it should be (1) lawful, (2) ethical, and (3) robust, both from a technical and a social perspective. However, attaining truly trustworthy AI concerns a wider vision that comprises the trustworthiness of all processes and actors that are part of the system's life cycle, and considers previous aspects from different lenses. A more holistic vision contemplates four essential axes: the global principles for ethical use and development of AI-based systems, a philosophical take on AI ethics, a risk-based approach to AI regulation, and the mentioned pillars and requirements. The seven requirements (human agency and oversight; robustness and safety; privacy and data governance; transparency; diversity, non-discrimination and fairness; societal and environmental wellbeing; and accountability) are analyzed from a triple perspective: What each requirement for trustworthy AI is, Why it is needed, and How each requirement can be implemented in practice. On the other hand, a practical approach to implement trustworthy AI systems allows defining the concept of responsibility of AI-based systems facing the law, through a given auditing process. Therefore, a responsible AI system is the resulting notion we introduce in this work, and a concept of utmost necessity that can be realized through auditing processes, subject to the challenges posed by the use of regulatory sandboxes. Our multidisciplinary vision of trustworthy AI culminates in a debate on the diverging views published lately about the future of AI. Our reflections in this matter conclude that regulation is a key for reaching a consensus among these views, and that trustworthy and responsible AI systems will be crucial for the present and future of our society.Comment: 30 pages, 5 figures, under second revie

    Automated identification and behaviour classification for modelling social dynamics in group-housed mice

    Get PDF
    Mice are often used in biology as exploratory models of human conditions, due to their similar genetics and physiology. Unfortunately, research on behaviour has traditionally been limited to studying individuals in isolated environments and over short periods of time. This can miss critical time-effects, and, since mice are social creatures, bias results. This work addresses this gap in research by developing tools to analyse the individual behaviour of group-housed mice in the home-cage over several days and with minimal disruption. Using data provided by the Mary Lyon Centre at MRC Harwell we designed an end-to-end system that (a) tracks and identifies mice in a cage, (b) infers their behaviour, and subsequently (c) models the group dynamics as functions of individual activities. In support of the above, we also curated and made available a large dataset of mouse localisation and behaviour classifications (IMADGE), as well as two smaller annotated datasets for training/evaluating the identification (TIDe) and behaviour inference (ABODe) systems. This research constitutes the first of its kind in terms of the scale and challenges addressed. The data source (side-view single-channel video with clutter and no identification markers for mice) presents challenging conditions for analysis, but has the potential to give richer information while using industry standard housing. A Tracking and Identification module was developed to automatically detect, track and identify the (visually similar) mice in the cluttered home-cage using only single-channel IR video and coarse position from RFID readings. Existing detectors and trackers were combined with a novel Integer Linear Programming formulation to assign anonymous tracks to mouse identities. This utilised a probabilistic weight model of affinity between detections and RFID pickups. The next task necessitated the implementation of the Activity Labelling module that classifies the behaviour of each mouse, handling occlusion to avoid giving unreliable classifications when the mice cannot be observed. Two key aspects of this were (a) careful feature-selection, and (b) judicious balancing of the errors of the system in line with the repercussions for our setup. Given these sequences of individual behaviours, we analysed the interaction dynamics between mice in the same cage by collapsing the group behaviour into a sequence of interpretable latent regimes using both static and temporal (Markov) models. Using a permutation matrix, we were able to automatically assign mice to roles in the HMM, fit a global model to a group of cages and analyse abnormalities in data from a different demographic

    Global markets are currently immersed in two all-encompassing and unstoppable processes: internationalization and globalization. While the former pushes companies to look beyond the borders of their country of origin to forge relationships with foreign trading partners, the latter fosters the standardization in all countries, by reducing spatiotemporal distances and breaking down geographical, political, economic and socio-cultural barriers. In recent decades, another domain has appeared to propel these unifying drives: Artificial Intelligence, together with its high technologies aiming to implement human cognitive abilities in machinery. The “Language Toolkit – Le lingue straniere al servizio dell’internazionalizzazione dell’impresa” project, promoted by the Department of Interpreting and Translation (ForlĂŹ Campus) in collaboration with the Romagna Chamber of Commerce (ForlĂŹ-Cesena and Rimini), seeks to help Italian SMEs make their way into the global market. It is precisely within this project that this dissertation has been conceived. Indeed, its purpose is to present the translation and localization project from English into Chinese of a series of texts produced by Bioretics© S.r.l.: an investor deck, the company website and part of the installation and use manual of the Aliquis© framework software, its flagship product. This dissertation is structured as follows: Chapter 1 presents the project and the company in detail; Chapter 2 outlines the internationalization and globalization processes and the Artificial Intelligence market both in Italy and in China; Chapter 3 provides the theoretical foundations for every aspect related to Specialized Translation, including website localization; Chapter 4 describes the resources and tools used to perform the translations; Chapter 5 proposes an analysis of the source texts; Chapter 6 is a commentary on translation strategies and choices
