Vice Chancellors Interdisciplinary Research Challenge Fund Selection Event

Posted on

On Monday 25 February, researchers came from across UWE Bristol to present their project ideas as part of the Vice Chancellors Interdisciplinary Research Challenge Fund. This diverse group covered a variety of areas, from the emerging markets in breast milk to reimagining dead celebrities in film, and AI training bots for healthcare professionals.

The Vice Chancellors Interdisciplinary Research Challenge Fund is an opportunity for UWE researchers to seek up to £25,000 funding to develop exciting new research projects with colleagues working in different fields from across this university.

The fund had 83 applications in January, of which 15 were invited to pitch their project for 5 minutes at the event, in the hope of being successful for the competitive Challenge Fund.

Attendees at the event were asked to help decide which projects they thought should be funded, with Research, Strategy and Implementation Group (RSIG) making the final decision.

11 of 15 projects were successful on the day. Information on the 11 successful projects can be found below.

The event was a great opportunity to gain an insight into the quality and breadth of research projects undertaken across UWE Bristol.

Plants grown from seeds that orbited earth to go on show at national event

Posted on

Tomato and rocket plants grown at the University of the West of England (UWE Bristol) from seeds that were taken into space in a rocket and orbited the earth, are to feature as part of a research event in London in January 2018 that will bring together leading experts on radiation.

The event in Westminster from 15-17 January 2018, will display findings from a national consortium involved in the UK-wide £5.6m Radioactivity and The Environment (RATE) project. Its aim is to determine how best to safeguard human health from releases of radioactivity from nuclear power plants or nuclear waste repositories.

UWE Bristol is part of the TREE consortium, which won the THE Research Project of the year award in 2016, and will display the plants grown from the seeds as part of its exhibit.

The rocket seeds were sent up with astronauts in a Soyuz space rocket as part of a collaboration between the European Space Agency and the Royal Horticultural Society. They were kept in the International Space Station where British astronaut Tim Peake monitored them for six months. During that time, the seeds were exposed to radiation from cosmic rays that exist in space.

After they were returned to earth in June 2016, UWE Bristol PhD student Nicol Caplin from the Faculty of Health and Applied Sciences conducted experiments on the rocket seeds. The objective is to determine the effects of radiation on plant development and whether the seeds ‘remember’ their time orbiting earth and therefore change their growth in response to stressful conditions.

After planting the rocket seeds in early 2017, the University also acquired some tomato seeds in November 2017 that had been taken up to space by the Canadian Space Agency.

Findings from the UWE Bristol tests on both sets of seeds are expected to be revealed in spring 2018.

Professor Neil Willey, who is overseeing the project, said, “The dose of radiation the seeds were exposed to in space is eqivalent to the levels found in some parts of the Chernobyl exclusion zone. As part of our overall research on how radiation affects plants, we wanted to test the seeds in a controlled environment.”

Professor Willey, who is one of the world’s leading experts on the effects of radiation on plants, is one of many researchers involved in the RATE project. “The building of a new generation of nuclear power stations, and the fact that the UK does not have a permanent nuclear waste repository led to this project,” said Professor Willey.

RATE involves three consortia, each examining different parts of the environment such as rocks, sediments and wildlife, which could be affected by increased radiation levels. UWE Bristol researchers are focusing their work on plant species, and have grown plants in the laboratory after applying the same levels of radiation as in Chernobyl. “The problem with a lot of data from Chernobyl is that scientists take individual plant samples and make measurements, but they have no idea what happens to them over several generations under controlled conditions. So we have applied Chernobyl levels of radiation over multiple generations of plants and followed what has happened,” said Professor Willey.

Based on their research, Professor Willey said he and colleagues believe that current reference levels of radiation stipulated by the regulator, in other words the amount of exposure there needs to be before the environmental regulator has to start investigating, do not need to be modified.

The London event for goverment, regulators and industry is organised by the Natural Environment Research Council (NERC).

Helping India to help itself with water management and reforestation

Posted on

Dr Mark Everard is driven by a desire to shape the direction of development and influence world views about sustainability, given his love of nature. This drive has taken him all over the world and most recently to India, where he is working on two projects. One involves reforestation in the southern state of Tamil Nadu, the other pertains to water management in the north-west state of Rajasthan. “I think, globally, people have forgotten the importance of nature and my work is to help re-invent an ecologically based economy,” says the environmentalist, who is Associate Professor of Ecosystem Services at the University of the West of England (UWE Bristol).

Tamil Nadu

One element of Everard’s work in India is in partnership with The Converging World (TCW), a charity that helps regions in India work towards low-carbon energy production and development. One of the charity’s activities is to install wind turbines before recycling a proportion of operating surpluses into reforestation across the country.

The beginnings of a forest at Nadukuppam

Reforestation, the natural or intentional restocking of existing forests and woodlands, provides multiple benefits. First there is the positive impact on people and nature, including hydrological buffering (helping with flood reduction and water resource regenerations), biodiversity enhancement, microclimate, and production of food and medicinal resources. A 40 year-old restored forest at Pitchandikulam demonstrates this. Tended from initial plantings on degraded farmland, it now hosts a diversity of wildlife, medicinal plants and a cold microclimate.

Then there are the carbon and climate benefits. By analysing data on carbon storage in the region’s typical forests, Everard and colleagues have demonstrated that an area of forest restored by incremental investments throughout the operational life of a wind turbine can sequester 3,000 times more carbon dioxide than that averted by the wind turbine.

Along with partners, Everard is involved in an ongoing reforestation programme around Nadukuppam village.  The planting of young trees began two years ago, and the involvement and empowerment of local people has played a vital role in its progress. The academic has now contributed to two scientific papers about the scheme.

Rajasthan

In India’s largest state, Everard is involved in a different environmental issue: water management. Rajasthan is a desert state and is today experiencing rapidly depleting groundwater levels and increasing geological contamination of the water, as mechanised pumping of deep groundwater becomes more common.

The region contains many traditional water management methods attuned to local geography, rainfall and culture. Unfortunately, a lot of this traditional water wisdom is lost today, according to the academic. “When the water levels decline, traditional water extraction techniques may cease to work, so interest in communal efforts to replenish it are displaced by competitive pumping of receding water,” he explains.

The environmentalist therefore looks at success factors in cases where people have reversed the cycle of degradation.  He collaborates with NGOs working with local people to restore traditional water harvesting solutions, as well as more modern innovations that complement local hydrology, geography and cultural perspectives. Such solutions can help intercept infrequent and increasingly erratic monsoon rains, enabling them to percolate into groundwater insulated from the region’s high evaporation rate and available for year-round access. In partnership with Wells for India and to highlight these effective methods, Everard is shortly publishing a guide in Hindi and English documenting over 30 ‘water wise’ water harvesting techniques in the region.

For example, monsoon run-off can be harvested using a ‘Johad’ (semi-circular mound of earth) that is adapted to drainage lines on sloping land with a permeable surface. The water is detained and able to recharge soil moisture and shallow groundwater, accessible year-round using open wells. Other solutions are adapted to where the land is sloped or flat, permeable or impermeable.

Using this evidence, Everard communicates with highly placed officials in the Rajasthan government to remind them of such water resource recharge practices that have kept communities in the region viable over centuries. The academic says that authorities are beginning to recognise the need to rebuild ecosystem vitality from the bottom up.  “The Additional Chief Conservator of Forests in the Government of Rajasthan has recognised that the work we have published at UWE Bristol contains jigsaw pieces useful in converting high-level aspirations into practical reality.” Everard has already published three papers on this topic with three more in the pipeline.

Public inquiries: a way to draw a line in the sand, or avoid accountability?

Posted on

When gross negligence occurs in a hospital or a public organisation is suspected of acting inappropriately in a murder investigation, the victims’ families often want to hold someone accountable. For them, public inquiries are a chance for those responsible to apologise. Dr James Murphy from the University of the West of England (UWE Bristol) researches the language used in public inquiries and the role blame plays in them. He has discovered that the victims’ loved ones do not always get the outcome they expected.

Over a six-month period in 2007 and 2008, more than 30 people died in three hospitals in an area of Northern Ireland as a result of an outbreak of the hospital-acquired infection Clostridium difficile. The bacterium also infected several other patients, making them severely ill. It later emerged that poor hygiene and lack of information for patients and their families meant the infection was not contained in one part of the hospital. A subsequent public inquiry was set up to find out why this happened.

James_Murphy1.png

Dr James Murphy, who is senior lecturer in English language and linguistics at UWE Bristol, researches how such public inquiries are conducted, how blame is attributed, and how apologies are expressed. He has examined the C. difficile case, and other public inquiries such as the Bichard Report (which asked why the necessary background checks were not made before a school employed Ian Huntley as a caretaker – he later murdered two 10-year-old girls).

In the case of the hospital-acquired infection, the inquiry invited two distinct groups of witnesses: the blameless family members of the victims, and a second group of hospital staff who were potentially blameable for the spread of the infection. Murphy assessed the linguistic aspect of the questioning. Although he expected that the hospital employees would be interrogated in the same way as defendants in a criminal court, and that family members would be treated like friendly witnesses, he found the opposite happened.

Instead, family members (often still in trauma) were questioned with closed, leading questions, similar to prosecution questioning in court. This, says Murphy, was simply so that the inquiry could confirm facts in the case. Meanwhile investigators asked hospital staff open, less-restricted questions. Murphy says this was to gather more evidence to help the inquiry identify who was responsible.

The academic has also learned that public inquiries are framed in a way that shies away from blaming anybody. “A lot of families expect someone to take responsibility for what they have suffered,” explains Murphy. “However public inquiries are not necessarily allowed to blame anyone.” He explains that blame is often more implicit in inquiries, which by highlighting lessons learned, imply that someone did something wrong and is potentially to blame.

Apologies are also invariably avoided in such investigations, finds Murphy. “When people are asked to apologise, they often have a carefully crafted statement demonstrating sympathy or regret, without taking responsibility,” he explains. “On the whole in inquiries, people don’t apologise because they fear that, in doing so, they risk public litigation,” says the linguistics expert.

Murphy also found that those who could be blamed, usually do a lot of preparation work on how to deliver their answers before attending a public inquiry. “There is a lot of rehearsal beforehand,” he says. Families, on the other hand, are often less clear about what to expect.

In fact, Murphy’s most striking discovery is the disconnect between family members’ expectations from a public inquiry and what they get at the end. “They see it as a line in the sand whereby they can discover who was responsible and can then move on,” says the academic. However, the reports they receive after the process are too often legalistic, hard to read, and careful about how they frame the findings. “The families want a direct and straightforward result, but what they get is something indirect and implicit,” he explains. This can sometimes leave them feeling like there has been a cover-up, says Murphy.

To address the issues in public inquiries, James Murphy is writing a book, due out in 2018, called, ‘The Discursive Construction of Blame: Language at Public Inquiries.’ The academic hopes it will influence policy and positively impact how public inquiry reporting can be improved and how victims and their families can better prepare for their involvement in proceedings.

Says Murphy: “Public inquiries are a strong representation of our democracy. Historically we might have lynched somebody we thought was to blame, but public inquiries represent the rational end of blame and is the endpoint of how we’ve developed as a society.”

Alan Winfield – paving the way for ethical robots

Posted on

Man before machine

Professor Alan Winfield is a roboticist, a roboethicist, but above all he is a humanist. “I am of course interested in robots but I’m much more interested in people,” says Alan.

An academic at the University of the West of England (UWE Bristol), Alan researches cognitive robotics at the Bristol Robotics Laboratory (BRL), alongside his responsibilities for teaching, writing (including a blog) and public engagement.

One of his current projects aims to help companies avoid sending employees into dangerous environments. Along with project lead Manchester University and partner Birmingham University, he and his colleagues are designing robots to help decommission Britain’s legacy nuclear power plants in the hope of returning them to green field sites.

“When we can build robots that go into old nuclear facilities to explore, map, and dismantle them, we can potentially also develop robots that can go into other dangerous environments such as collapsed buildings after an earthquake or deep mines,” says Alan. Ultimately, this work could save people’s lives.

Over the last two decades, the roboticist has looked at how robots can be intelligent and he is working on a book on the nature of intelligence. It is perhaps his reflection on cognitive robotics that has also made him a roboethicist, someone who thinks about the governance frameworks that should determine how robots are designed, built and operated.

“A roboethicist is someone who makes it their job to worry about the possible societal, economic and environmental consequences of robotics and AI [artificial intelligence],” says Alan. Today, half of his working hours are devoted to roboethics.

An ethical framework for robot design

Although a self-professed optimist, one of Alan’s main worries about the future of robots and AI technology concerns the current lack of regulation and standards. He cites the example of driverless car autopilots. Although certain car manufacturers have undoubtedly tested their systems, they have not done so to any agreed national or international standards, says the scientist. “The world urgently needs safety standards for driverless car autopilots, as well as agencies to certify their safety and investigate when there is a crash – these don’t yet exist,” explains Alan.

International guidelines are also scarce around designing AI and intelligent robots ethically, and Alan is working hard to change this. As a member of the British Standards Institute (BSI) committee, he helped draft what could possibly be the world’s first ethical standard in robotics. Published in 2016, it addresses risks to individuals, society, and the environment. “I am very proud of our work on this,” says Alan, “as it provides a robot designer with a toolkit for assessing the ethical risks associated with what they are doing.”

Alan is also a member of the executive committee leading the IEEE Standards Association’s global initiative on ethical design of AI and autonomous systems. Within this initiative, he co-chairs the General Principles Committee, which is developing high-level principles applying to all AI and autonomous systems such as driverless cars, drones, medical diagnosis AIs, or even search engines. These principles propose that such systems should not infringe human rights, and that their functioning should be transparent. “The idea is to bake ethics in from the very beginning of the design process,” Alan explains.

The IEEE initiative published in December 2016 a draft set of ethical principles called ‘Ethically-aligned Design’, with the aim of advancing a public discussion of how intelligent technologies can be aligned to ethical principles that prioritize human wellbeing. To date, seven standards have spun out of the IEEE initiative and are now in development.

Awareness of ethics through education

Another way of embedding this sense of responsibility in robot designers is through education. In 2015, UWE Bristol began offering a module on the ethics of technology for its robotics and philosophy students. The reasoning behind this move is to encourage engineers to consider the ethical implications of their work, and invite philosophers to think about the practical impact and applicability of ethics on technology.

Overall, Alan believes robotics and AI have already brought many advantages to our lives. The BRL is working on a wide range of beneficial applications, such as assisted living robots that could help the elderly in their homes, robots to assist with keyhole surgery, and work place assistant robots to act as work mates in manufacturing. His advice to budding roboticists is clear: “Do good and always do work that is to the benefit of humanity, rather than purely to satisfy scientific curiosity or to make money.”

Reducing bad breath: how 20 years of research have helped us better understand halitosis

Posted on

A researcher at the University of the West of England (UWE Bristol) has devoted her work to a subject that some might find unpleasant or embarrassing: bad breath. Over the past two decades, Dr Saliha Saad and colleagues have tried to pinpoint the mechanisms behind oral malodour, also called halitosis, and how best to reduce it.  

A link between the biofilm on our tongue and oral malodour

While bad breath can be the result of eating strong-smelling foods like eggs, a meat morsel caught between the teeth, or gum disease, these lead only to temporary oral malodour. Dr Saad’s research examines more long-lasting, chronic halitosis in people who, despite living a healthy lifestyle with good oral hygiene, experience the symptom on a regular basis.

We humans carry 1.5kg of microbes, also called human microbiota, on the inside and outside of our bodies, found on our skin, in our intestines and in our mouths. At the back of the tongue is a biofilm, a collection of millions of bacteria within a thin, robust protective coating (which the bacteria excrete). Although researchers are still trying to identify all the possible causes of halitosis, they believe this film of microbes is responsible for oral malodour. “Our theory is that the more bacteria on our tongues, the higher the instance of smelly compounds found in our breath,” says Saad.

Through her research with Professor John Greenman, Dr Saad has learned that people with oral malodour may have it their entire lives. As a result, Saad and her team have worked with Colgate Palmolive, Philips, GSK, Procter & Gamble, Healthcare International, Boots, GABA and other oral hygiene companies to help them develop more effective toothpastes, mouthwashes or cleaning devices. “Brushing and flossing can reduce bad breath for a certain amount of time, but the challenge is to cut bad breath for longer. Our job is to show these companies whether their product has a longer lasting effect on oral malodour,” explains Saad.

Testing products that counteract bad breath

To try to achieve this, the researchers test anti-microbial samples the companies send them using a biofilm perfusion system. This involves gently scraping volunteers’ tongues to obtain the collection of microbes, before injecting the resulting liquid onto cellulose, a material that best represents the surface of a tongue. A fluid almost identical to saliva is then slowly drip-fed onto the biofilm to emulate the environment (including pH and temperature) found in a human mouth.

Once the bacteria reaches a steady state, the scientists inject controlled amounts of the unlabelled oral hygiene sample onto the microbes. “These products are invariably a type of toothpaste but we often don’t know what active ingredients they contain,” says Saad. The process of reduction in bacteria and smell is then measured over time.

Following this in vitro testing, the scientists conduct clinical trials by asking some 150 volunteers to test toothpastes or other oral hygiene products such as mouthwashes. The intensity of their malodorous breath is assessed both before and after the treatment using a SIFT-MS machine. The device uses a technique called ion flow-tube mass spectrometry to ‘smell’ the breath by providing a breakdown of the gases contained within it. “Generally the most odorous gases are the sulphides,” explains Saad.

Because machines and other measuring devices can sometimes be inaccurate, Saad herself also smells the volunteers’ breath. As a qualified organoleptic judge, she can categorise the odour by intensity and unpleasantness according to a set technique and scale. The participants are then provided with a toothpaste or mouthwash to test, with Saad checking their breath in the subsequent hours. Test results are subsequently analysed and sent on to the oral hygiene companies concerned.

UWE Bristol is unique in that it provides a course to train scientists to become organoleptic judges with Saad as their trainer. By the end of the five-day course the professionals, who are from all over the world, learn to use the sniffing test to diagnose oral malodour and assess the effects of treatment interventions in their own practices.

As for those who suddenly recognise that they have momentary smelly breath, perhaps just as they are about to walk into an interview, Saad proffers her advice for quick remedy. “Gently brush the back of your tongue,” says Saad. “But be careful not to damage it because if you brush too hard you could cause injury and infection.”
