This presentation examines processes of subjectification whereby Chinese gods affirm unique personas and engage humans and each other in intersubjective interactions. In so doing, it develops relational approaches to study divine-human sociability. The vast array of ritual techniques developed over the longue durée in China to allow the gods to “talk back” to humans and create bonds have allowed these gods to affirm themselves as persons and subjects – even though there was also resistance against such developments. This lecture will propose an overview of the ritual techniques available for such personification and subjectification processes and their historical development in the Chinese world. It will then explore some of the theoretical and comparative dimensions of such processes and their consequences for our understanding of subjectivity.

Until recently, there were two main ways of obtaining information about words and expressions. The first was to analyze large text data sets (corpora) and calculate the frequency with which words and phrases occur, as well as the typical contexts in which they occur. The second was to ask participants to provide subjective information about words and phrases, such as the familiarity of the stimuli or the age at which they are typically acquired. The development of large language models has given us a third option. Instead of asking participants for information, we can query large language models. The results show that the information obtained from those models is just as good and often even better than the information obtained from people, especially when the model is tuned to a few thousand stimuli.

Lu began his presentation with a brief outline of the role of functional nanomaterials in addressing global challenges and advancing green hydrogen technologies. He highlighted the critical importance of electrodes, membranes, catalysts and photocatalysts in enhancing the efficiency and scalability of electrolysis and photocatalysis systems, as well as the significance of solid-state storage materials in overcoming challenges related to hydrogen storage and distribution, noting that some low-pressure solutions are already in use.
Still, Prof. Lu emphasised that further technological innovations are needed to reduce costs and enhance performance. He explained that green hydrogen is a valuable energy carrier; it can not only contribute to decarbonisation in the power sector, but also act as zero-emission fuel for sea, land and air freight, which is crucial for the achievement of a net-zero future by 2050. In conclusion, Prof. Lu called on the academic community to accelerate the commercialisation of new materials for the construction of cost-effective hydrogen infrastructure, and urged researchers to bridge the gap between technology R&D and practical applications.

Human brain stores tremendous amount of knowledge about this world, which is the foundation of object recognition, language, thought, and reasoning. What’s the neural codes of semantic knowledge representation? Is the knowledge “roses are red” simply the memory trace of perceiving the color of roses, stored in the brain circuits within color-sensitive neural systems? What about knowledge that is not directly perceived by senses, such as “freedom” or “rationality”? I will present a set of studies from my lab that addresses this issue, including object color (and other visual) knowledge in several populations (congenitally blind humans, color blind humans, and typically developed macaques), and semantic neural representation in individuals with early language experience deprivation. The findings point to the existence of two different types of knowledge coding in different regions of the human brain – one conservative, based on sensory experiences, and one based on language-derived machinery that support fully nonsensory information. The relationship between these two types of knowledge coding will be discussed.

In this talk I examine the role of humanities research where nearly every aspect of human experience is turned into data and analysed, in many cases to model, predict and modify behaviour. As a result and through advances in computing technology, artificial intelligence systems have colonised traditional areas of humanities research, including linguistics and language studies. Today, large multimodal models (LMM) can process text, images, videos and sound, potentially leading to the development of algorithmic approaches to modelling society and culture. In this talk, I explore how humanities researchers can leverage the benefits and mitigate the risks of these latest technological developments and prepare scholars for the challenges which lie ahead. I provide some examples from the Digital Media and Society Institute (DMSI) at the University of Liverpool where communication and media researchers are working with data scientists to investigate how multimodal information is re-contextualised across online media platforms. This includes new methods for studying information distortions (e.g. misinformation, disinformation and memes) and public reactions to key events.

People are now regularly interacting with voice assistants (VAs), which are conversational agents that allow users to use spoken language to interface with a machine to complete tasks. The huge adoption and daily use of VAs by millions of people - and its increasing use for financial, healthcare, and educational applications - raises important questions about the linguistic and social factors that affect spoken language interactions with machines.
We are exploring issues of linguistic and social biases that impact speech communication in human-computer interaction - particularly during cross-language transfer, learning, or adaptation of some kind. In this talk, I will present two case studies illustrating some of our most recent work in this area. The first study looks at a case of cross-language ASR transfer. We find systematic linguistic and phonetic disparities in language transfer by machines trained on a source language to speech recognition of a novel target, low-resource language. The second study looks at a case of social bias in word learning by humans using voice-enabled apps. We find the word learning is inhibited when there are mismatching social cues presented by the voice and the linguistic information.
Together, along with highlights from other ongoing work in my lab, the aim of this talk is to underscore that human-computer linguistic communication is a rich testing ground for investigating issues in speech and language variation. Examining linguistic variation during HCI can enrich and elaborate linguistic theory, as well as present opportunities for linguists to provide insights for improving both the function and fairness of these technologies.
