Twenty-nine scholars of The Education University of Hong Kong (EdUHK) were among the top 2% in the Stanford list of the world’s most-cited scientists in 2020*.

This year, 18 have once again found a place on the prestigious list, while 11 scientists from the University have been included for the first time.

Their publications cover 12 different disciplines, including education, social psychology, environmental sciences, general mathematics, geriatrics, energy, general chemistry, marine biology and hydrobiology, organic chemistry, physical chemistry, urban and regional planning, and building and construction.

Prepared by a team of experts at Stanford University, the list ranks academics by the number of times their research has been cited against other authors in the subfield in which they work. The selection is based on the top 100,000 by C-score (with and without self-citations) or a percentile rank of 2% or better.

Along with the results of the 2020 Research Assessment Exercise, this list reflects the significant advances the University and its scholars are making. Apart from education, the broadening range of research areas cover the core field of education, as well as other related disciplines, through EdUHK’s Education-plus approach.

Poor sleep kills people through medical illnesses, traffic accidents (impaired concentration and decision making), and suicides (relating to mood disorders). Since joining The Education University of Hong Kong in 2015, Dr Esther Lau Yuet-ying, Associate Professor at the Department of Psychology, has been conducting a long-term research programme that sheds light on the underlying mechanisms of sleep deprivation and its negative effect on emotions, cognition and daily functioning. The findings have been disseminated via public media and workshops to education and government bodies and have led to changes in community attitudes and school policy. They have also resulted in the establishment and strengthening of clinical and consultation support for sleep health in universities and government departments.

Building on her research and clinical experience, Dr Lau has shown how an understanding of the cognitive and emotional consequences of sleep loss or gain inform clinical understanding of sleep disturbances and related psychopathologies, and can influence public health policies and organisational practices. Using online panel studies, laboratory experiments, physiological measures, clinical assessments and subjective reports, Dr Lau’s team investigated the predictors, mediators and consequences of poor sleep.

Dr Lau’s research demonstrates that the quantity and quality of sleep directly affect our outlook on life and the decisions we make. She has built a unique, 10-year longitudinal dataset of over 8,000 students and community adults with over 100 psychosocial-spiritual variables per person to generate the first empirical evidence in the world that sleep quality predicts optimistic or pessimistic attitudes to life, directly and indirectly, through its effect on mood. She also identified a long-term increase in risk taking among young adults who habitually sleep less or irregularly.

Collaborating with local and overseas institutions, Dr Lau and her team uncovered links between sleep, clinical depression and emotional processing biases. They collaborated with the University of Oxford to develop and validate a Chinese version of the Sleep Condition Indicator (SCI) for clinical and research use.

Through extensive media coverage, sleep education, community engagements and professional training, Dr Lau’s research-based advocacy for healthy sleep practices for well-being has resulted in (1) shifts in attitudes and knowledge among both the general public and professionals; (2) a new school policy for a later start time; (3) the creation of a new sleep health initiative in the Hong Kong Police Force (HKPF); and (4) early identification of mental health issues by screening college students for sleep-related problems.

Dr Lau also provided both local and global community sleep education through 17 interviews on popular public television programmes, radio broadcasts and newspapers. Her longitudinal research in a boarding school showed that a delayed school start time helps student well-being by increasing the length and quality of their sleep, resulted in a successful policy change at the school.

In collaboration with police psychologists, Dr Lau enhanced the sleep health of police officers through a strategic, multifaceted programme, including seminars for 300 officers and family members, and training on sleep assessment and interventions for all police clinical psychologists. Dr Lau’s evidence-based suggestions helped police officers overcome sleep barriers and provided credible information to share with family and friends, according to a senior HKPF clinical psychologist.

To detect and alleviate academic and mental health issues rooted in sleep problems in college students, Dr Lau trained counsellors in 14 local tertiary institutions to carry out sleep assessments and interventions. Not only did 90% of the counsellors indicate a sharp improvement in their understanding of sleep, 100% of them found her talk beneficial for their practice, evidenced by requests to incorporate the SCI into their practice.

The Hong Kong SAR Government’s 2018-19 Health Behaviour Survey showed that around 96% of residents aged 15 or over consumed less than five portions of fruit and vegetables per day. Added to this, almost 10% of these people ate processed meat at least once a day, on average. The World Health Organisation states that an unhealthy diet and lack of physical activity are leading global risks to health, and its member states have agreed to halt the rise of diabetes and obesity in adults, teenagers, and of overweight children by 2025.

With this in mind, Dr Louisa Chung Ming-yan at the Department of Health and Physical Education of The Education University of Hong Kong and her team have developed the eDietary Platform, an app for users to record their diet and monitor what they eat and drink. “To change eating habits, we can’t merely deliver lectures on nutrition. We need a record of scientific facts,” explained Dr Chung.

Users input their dietary record onto the app. Any food not already on the list can be added by simply uploading a photo. The app then gives users a bespoke nutrition report, taking into account personal details such as age, gender, height and weight.

The project team was awarded funding by the Food and Health Bureau under the Health Care Promotion Scheme. Through the feedback received, researchers found that using the eDietary app made younger adults more capable of matching food products to categories. Participants therefore understand how to reduce the risk of health problems and vulnerability to diseases and are encouraged to develop their own eating plan in terms of food and portion size change. In testing, the complete switch to healthy eating took 12 weeks.

As a start, the app has already been downloaded over 4,500 times to date, and its effectiveness was trialled in a study on how the use of such technology enhances the eating behaviour of young adults. “We formulated and tested the theory on eating behaviours when people monitor their diets online,” said Dr Chung. People who have used the app have noted that it makes them realise the importance of enjoying healthy food. “It has encouraged me to develop the habit of recording my daily intake,” said one. They suggested that the app could be used by young adults and children, as it helps youngsters learn about food classification, nutrients and quantities.
