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.

Every day, we are bombarded by information. From the morning paper to news and on social media throughout the day. We might not think of it much now but, that’s an overwhelming amount of information.
And it can be dangerous in some cases. From fake news or inaccurate information, or the information heavily biased.
This, in turn, impacts you. It impacts who you vote for, what you buy and maybe how you feel. In a sense, the information we consume dictates our entire life.
As a result, critical thinking skills become our saving grace in our lives. It’s a skill that so many of us lack in our lives and yet it’s one of the most critical.

In his presentation, Prof. Chen first gave a brief introduction to the United Nations’ 17 Sustainable Development Goals (SDGs) as well as the SDG monitoring practices in Mainland China. He pointed out that the Nation has adopted the high quality sustainable development concept, which emphasises harmonising the social, economic and environmental aspects in national development. Next, he elaborated on a pilot project that he led to measure Deqing County’s progress towards SDGs using geospatial and statistical information. The project was selected by the UN Department of Economic and Social Affairs as one of the first 16 good SDGs’ practices in 2020. After that, Prof. Chen shared that the achievement of sustainable development requires holistic and systematic research to build a digital governance system that can provide the basis for the scientific and orderly development of national territorial space. He also explained how territorial space sustainability studies can help unveil and analyse various patterns, such as the distributions of population, enterprises and public service facilities, and the relationships between them. To conclude, Prof. Chen introduced the national program on the development of the Realistic Geospatial Landscape Model (3dRGLm), which can generate digital description and representation of the real 3D geospatial spaces. This new geographic information system can support the Nation in achieving natural resources management and high quality sustainable development.

PAIR distinguished lecture series: an overview of high performance computing and future requirements
In this talk, we examine how high performance computing has changed over the last ten years and look toward the future in terms of trends. These changes have had and will continue to impact our numerical scientific software significantly. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed, and parallel environments. Some of the software and algorithm challenges have already been encountered, such as the management of communication and memory hierarchies through a combination of compile-time and run-time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run-time environment variability will make these problems much harder.

Globalisation and advances in information and communication technology have resulted in a 24/7 work environment characterised by rapid change, a greater sense of competition, and an explosion in access to communication and information. These pressures compound stress related to workload and information processing – this not only reduces performance but can lead to a reduced sense of meaning and purpose as well as physical and mental health issues. Understanding stress and how to boost your resilience to it are essential skills for contemporary leaders and play a vital role in managing the demands you face at work. This course will focus on the nature of stressors facing leaders in today’s work environments and how to deal with them. You’ll explore personal resilience – your capacity to withstand and cope with stress – and strategies for self-management, motivation and organisation. You’ll also learn how resilience is impacted by health and social relationships.

Managers have tried various strategies and perks to boost employee engagement—all with little impact on long-term retention and performance. But now, neuroscience offers some answers. Through his research on the brain chemical oxytocin—shown to facilitate collaboration and teamwork—Zak has developed a framework for creating a culture of trust and building a happier, more loyal, and more productive workforce.
By measuring people’s oxytocin levels in response to various situations—first in the lab and later in the workplace—Zak identified eight key management behaviors that stimulate oxytocin production and generate trust: (1) Recognize excellence. (2) Induce “challenge stress.” (3) Give people discretion in how they do their work. (4) Enable job crafting. (5) Share information broadly. (6) Intentionally build relationships. (7) Facilitate whole-person growth. (8) Show vulnerability.
Ultimately, Zak concludes, managers can cultivate trust by setting a clear direction, giving people what they need to see it through, and then getting out of their way. In short, to boost engagement, treat people like responsible adults.
