The latest service to be revolutionised by drones might not be package delivery or internet connections but the far more valuable service of pollination. Researchers in Japan have been exploring the potential of using miniature drones covered with sticky hairs to act like robotic bees to counter the decline of natural pollinators.

Writing in a paper in the journal Chem, the team demonstrated their drone on an open bamboo lily (Lilium japonicum) flower. With a bit of practice, the device could pick up 41% of the pollen available within three landings and successfully pollinated the flower in 53 out of 100 attempts. It used a patch of hairs augmented with a non-toxic ionic liquid gel that used static electricity and stickiness to be able to “lift and stick” the pollen. Although the drone was manually operated in this study, the team stated that by adding artificial intelligence and GPS, it could learn to forage for and pollinate plants on its own.

But it takes more than just sticky hairs to be a good pollinator. As someone who studies pollinating insects, I think these drones have a lot of catching up to do to match our existing pollinators, which include bees, butterflies and even some larger animals, in all their diversity. But it is always good to see science learning from nature and these studies also help us to appreciate the wonders of what nature has already provided.

Pollination is complex task and should not be underrated. It involves finding flowers and deciding if they are suitable and haven’t already been visited. The pollinator then needs to successfully handle the flower, picking pollen up and putting it down in another plant, while co-ordinating with its team and optimising its route between flowers. In all of these tasks, our existing pollinators excel, their skills honed through millions of years of evolution. In some cases, our technology can match them and in others it has some way to go.

The three major factors that make insect pollinators such as bees so good at what they do are their independent decision making, learning and teamwork. Each bee can decide what flowers are suitable, manage their energy usage and keep themselves clean of stale pollen.

Modern drones can already achieve this level of individual management. As they have the technology to track faces, they could track flowers as well. They could also plot routes via GPS and return to base for recharging on sensing a low battery. In the long run, they may even have a potential advantage over natural pollinators as pollination would be their sole function. Bees, on the other hand, are looking to feed themselves and their brood, and pollination happens as a by-product.

The areas where drones need development, however, are learning and teamwork. Flowers are also not always as open and simple as those of the bamboo lily and quite a few of our commercially pollinated food resources have much trickier flowers (such as beans) or need repeated visits (such as strawberry flowers) to produce good fruit.

To solve this, bees learn and specialise on a specific flower so they can handle them quickly and efficiently. They also learn the position of rewards to learn the best routes. With all individuals in the team doing this, they divide their labour and get a lot more done. To replicate this in drones would involve some serious programming and the ability of the drone to change its behaviour or shape to adjust to flowers, or having different drones for different jobs as we have different species of pollinator.

Having more than one drone requires co-ordination and preferably non-centralised control, whereby individual drones can make their own decisions based on information from their colleagues and a set of simple rules. Honeybees have the ability to recruit others to rich floral rewards using movements known as the waggle dance. Bumblebees can tell if a flower has already been visited by the smell of the footprints left by previous visitors. All these adaptations make our pollinators very efficient at what they do. Similar skills would have to be developed into a team of pollinating drones in order for them to work as efficient pollinators.

Although I feel that these robots are a long way away from becoming the optimal pollinators, they may well have a place in our future. I could see these drones being used in the environments that are unsuitable for natural pollinators, such as a research lab where precision is needed in the crossing of plant breeds. Or even in a biodome on Mars where a swarm of honeybees may not be the safest solution. It will be interesting to see what else robotics can learn from our insect pollinators and what they can improve upon.

Working in partnership with businesses: how research can provide solutions

This year’s Bournemouth Research Chronicle explores the ways in which our academics are working with students, our local community and with partners abroad.  In the latest edition Shelley Ellis, Lecturer in Performance Analysis, shares her story of working with South Coast Canoes to tackle the problem of adapting sporting equipment to fit women.  Below, Simon Rham, owner of South Coast Canoes explains his company’s involvement in the project.

“I first got to know more about this subject after Shelley applied to become a South Coast Canoes Team Paddler. Shelley represents us on and off the water and has helped grow our profile with her coaching and expertise,” explains Simon.

“Shelley told me about the subject she was researching and to help her with this we have held talks both at the shop and at a charity paddling event in Devon which we run. These talks were extremely interesting and helped to increase the awareness within the paddling community of what Shelley is trying to achieve.  We’ve given Shelley access to our social media accounts to help her raise the profile of her research area.”

“One of the other ways we’ve been able to help Shelley is by supporting her to find particular pieces of equipment which she needs for her research.  For example, Shelley was trying to purchase paddle shafts from New Zealand, which have power meters built in.  These are great for measuring performance and are a good tool for Shelley’s research.”

“She needed some blades to go with the paddle shafts, so I put her in touch with AT Paddles, who are based in the USA.  They kindly sent over some samples for her to use as part of her research.  With this equipment, Shelley has been able to gather more data out on the water to help her better understand how subtle differences in seat height can affect paddling performance.  We will continue to work with Shelley on this as it is an extremely interesting area of research.”

Getting involved in conservation in Indonesia: an undergraduate perspective

In July 2016, a group of undergraduate students travelled to Indonesia as part of the ‘Landscape Ecology and Primatology’ (LEAP) research project.  For many it was their first experience of living and working in the tropics.  Below, Ecology and Wildlife Conservation student, Ewan Hitchcoe shares some insights into the trip.

For more information about the LEAP project, take a look at the latest edition of the Bournemouth Research Chronicle.

The first part of the trip was based at the Ketambe Forest research centre, located in Aceh province. The forest here is part of the network of forests that makes up the Gunung Leuser National Park. The Ketambe research centre was built by Dr. Herman D. Rikjsen, a Dutch researcher, in 1971 and was the first Orang-utan research station in the world.  Since its inception, the station has provided a base for many scientific studies carried out by well-known Orang-utan field researchers and their collaborators.  The long-term nature of the station means that it’s been possible to carry out studies that help both the public and scientific community with an understanding of adaptive strategies, life history variables and social behaviour of animal populations.

Our group of BU students spent a total of 4 days at Ketambe, one half of the group staying at the research station for two days and the other half staying across the nearby river at a guesthouse, before swapping over. Ketambe was our first introduction to the rainforest and much of our time was spent on extended treks through the forest where we were lucky enough to experience a multitude of flora and fauna including many old growth trees, insects, birds and primates, as well as stunning forest landscape features such as rivers and waterfalls.  Both groups were lucky enough to see wild Orang-utans at Ketambe – a mother and a young infant.

Here at Ketambe, we learned field skills, such as how to use the audio array method (spatial explicit capture-recapture) for assessing primate population density. This involved a 4am start and trekking into the forest, where we set up 3 different listening stations from which to record the morning calls of Orang-utans, Siamangs, Gibbons and Thomas leaf monkeys.  We took note of the time, species, bearing and approximate distance, so that we could triangulate primate group positions later back at camp. We also learned some other techniques for monitoring bio diversity such as butterfly trapping and handling under the instruction of MRes student and LEAP team member Emma Hankinson.

After a pit stop back at Medan our next destination was at Serbajadi Aceh Timur to meet with Tezar Pahlevie and the elephant handlers of the Aceh Conservation Response Unit (CRU). Here we learned how this dedicated team use low tech methods such as fireworks or planting citrus crops to try to dissuade elephants away from people and crop plantations. We also learned how as a last resort the CRU uses trained elephants (taken from the wild as ‘problem’ elephants that would have most likely come to harm from farmers trying to protect their crops) to fight and effectively scare off wild herds. We were also privileged enough to be able to engage with the elephants by helping to wash and feed these magnificent creatures, becoming acutely aware of how truly powerful they are.

The next day we were invited to Leuser Conservation Forum offices, where Rudi Putra and Tezar Pahlevie gave us a presentation about the excellent work being carried out in Aceh and beyond. The presentation stressed the importance of and many reasons for protecting the rain forest. We learned about their success stories, as well as some of the problems that hinder the team’s progress.  The biggest recurring theme is a severe shortage of and sometimes misappropriation of government funds.  In a developing nation often struggling to provide housing, water, healthcare and education for its citizens, habitat and wildlife conservation is understandable not at the top of the government’s priority list.  It quickly became clear that the issues faced here and throughout Indonesia are daunting and are not going to be resolved easily.

High Dynamic Range Point Cloud Rendering

We would like to invite you to the latest research seminar of the Centre for Games and Music Technology Research.

RSImg

Speaker: Dr Carlo Harvey

 

Title:     High Dynamic Range Point Cloud Rendering

 

Time: 2:00PM-3:00PM

Date: Wednesday 15th February 2017

Room: PG11, Poole House, Talbot Campus

 

Abstract: As a new member of staff, I feel it useful to use this opportunity to briefly present my previous research in the field of physically based rendering.

This seminar however, will be mainly focussed upon introducing the challenges that enshrine my current research into synergising High Dynamic Range and Point Cloud data. Specifically the work presented will introduce a technique in development to flip the standard paradigm of geometry triangulation and re-topologisation from Point Cloud data. Instead, this fairly laborious, and often manual process, is optimised away from the rendering pipeline and rendering is instead conducted on a set of generated point lights and estimated surfaces reconstructed from a sparse set of points.

 

We hope to see you there.

Humanising care: how research is making a difference to hospital care

For many people, going into hospital can be a very difficult time and the small things that staff do can make the experience less stressful – taking the time to offer reassurance, communicating clearly and going the extra mile in a myriad of different ways.  A joint project between staff and patients at the Royal Bournemouth Hospital’s Stroke Unit and researchers at Bournemouth University has been exploring these humanising touches and how they improve care.

Nikki Manns, Ward Sister and Caroline Bagnall, Specialist Speech and Language Therapist, are both part of RBH’s Stroke Unit and have been involved in the humanising care project since the beginning.  Below, they explain what motivated them to take part and how the project has been making a difference.

“I wanted to get involved because it seemed a good way of sharing our patients’ experiences,” explains Nikki, “I wanted our staff to hear patient stories from their perspective, so that we could get a better understanding of their journey on the stroke ward.  For me, that was one of the most valuable parts of the project.”

“I was interested in how we could improve our services,” says Caroline, “I was fascinated by the idea of humanised care and looking at how we could improve services from a human perspective.  I loved being involved in the project.  For me, one of the most important things was having the time to reflect on our work as staff and with patients.  It was very valuable to be able to think about each stage of the journey and explore how it felt to both staff and patients,” continues Caroline.

“I found it a very motivating process,” says Nikki, “Our staff really engaged with the project, which continued even after we finished.  Staff have been sharing snippets and stories with the rest of the team and really taking on board what we talked about.  They’ve been looking at all sorts of different things we could change in our working environment.”

“It’s been really  inspirational seeing people from all parts of the team getting together and coming up with new ideas and new projects that they want to lead.  They’ve been really motivated to improve patient care and experience.  The feedback they’ve got as a result has been great and has helped them to see how they’re making a difference.”

“One of the main things we’ve become aware of through the project is the power of small things,” says Caroline, “When people are in a new environment, they can feel quite overwhelmed.  The little things that we do as staff can help them to feel a little less vulnerable and scared when they have a huge event happening in their lives.  It’s been good to be reminded of the difference a small gesture can make.”

“Normally we get most of our feedback once people have left hospital,” says Nikki, “It’s usually through the friends and family survey sent out once people have been discharged.  Being face-to-face with our patients and hearing their experiences has been incredibly powerful.  It’s got so much more value to it.”

“I’d really like to see the humanising care project continue and rolled out in other parts of our NHS Trust.  All patients should have a fantastic experience, regardless of their age or what ward they’re on and I think all healthcare staff can learn something from being involved.”

To find out more about the humanising care project, take a look at the latest edition of the Bournemouth Research Chronicle.

Taking part in an archaeology field trip: exploring Madinat al-Zahra

As part of her degree, archaeology student Josie Hagan, had the opportunity to join Professor Kate Welham at a dig in southern Spain.  Josie and Professor Welham formed part of the international team exploring the medieval palace city of Madinat al-Zahra.  Below, Josie shares her experiences of fieldwork.

“When I found out I would be going to Spain I was obviously extremely excited but also nervous!  I had participated in geophysical survey before in Wales and England but I knew that working in an entirely different country would bring different challenges,” explains Josie, “I really wanted to brush up my skills in geophysics (there is always more to learn), experience a different country’s archaeology and their outlook on how to manage archaeologically important sites.”

“I also wanted to meet more archaeologists! There is always so much you can learn from just speaking to other people and it is always nice making new friends across the globe.”

“While I was out in Spain, we used geophysical survey over what was the city at the bottom of Madinat Al-Zahara. We worked in small teams or pairs, as there was so much ground to cover, and this involved getting help from local Spanish archaeology and history students. Their English was amazing, and they were a brilliant team to work with, as everyone seemed keen to learn how to use the equipment.”

“The Spanish students were quite new to using some of the equipment, so it was nice to pass on some of the skills we had learned.  Towards the end of our time there, the Spanish students were taking their own surveys with us assisting.  Teaching someone else is great way of learning how much knowledge you have!”

“At the end of each day we also had the opportunity to help with downloading and processing the data we had gathered. This is really great experience and is also nice to see how our hard work was coming together on the screen.”

“My advice to anyone who is thinking of studying archaeology is to go for it! I didn’t do archaeology at A-level or have any real experience before I came to university but I have absolutely loved the course, found the teaching and content amazing and it’s just such a varied degree.  There is plenty to learn and I really appreciate the variety of lectures, seminars, lab sessions and field work, which keeps it all really interesting. “

“And for anyone thinking of going on a field trip – just go for it!  It will be scary at first but if you are happy to work hard and willing to learn then you will bring so much more to the trip then you can imagine.”

To find out more about the project and Professor Welham’s work, take a look at the latest edition of the Bournemouth Research Chronicle – BU’s research magazine.

Declining sport viewership shows why we should keep it on free TV

Declining television viewership for sporting events might suggest that those of us who heralded sport as a potential saviour of traditional broadcast media had it all wrong.

In Australia, ratings for the recent one-day cricket matches were dire and the Australian Open tennis was mixed. In the UK, viewership for the British Open golf collapsed by 75% and even the once untouchable English Premier League (EPL) has seen declines in certain timeslots. Meanwhile, Formula 1 is in a slow decline that has been ongoing for almost a decade, and the NFL is down year over year as well.

But putting the numbers under closer inspection reveals other explanations. Many of these leagues are moving onto pay TV or are the victims of changing sporting tastes. Rather than dampening broadcaster enthusiasm for live sport, they show why sport should remain on free TV.

A closer look at the numbers

The Australian Open television ratings are maybe the most interesting of the bunch. The women’s final won the night in Australia, but with fewer viewers than previous years. The men’s final was a huge drawcard and viewing figures were well up from the previous year’s final. Worldwide, however, both the men’s and women’s finals were significantly up on previous years.

So, what happened to Australian tennis viewership when the women’s final was on? More sport! The women’s tennis final was up against the final of the Big Bash League (BBL) cricket, which attracted more than a million viewers to come a close second in the ratings.

The increased popularity of the BBL shows fans aren’t cutting out or cutting down sport consumption. Instead, they are substituting one format of cricket, or one sport, for another. Cricket Australia launched the BBL for this exact reason, and it has been a tremendous success.

As BBL shows, the decline in one sport can be driven by consumer sport preferences changing, rather than people abandoning sport altogether.

The EPL and Champions Leagues, previously bastions of strong viewership, have also experienced fluctuations in audience figures. That said, a closer look implies that a lack of marquee fixtures in the EPL and the qualification of historically smaller clubs (i.e., Leicester) have diminished audience interest to some extent.

Moving to pay TV

Another explanation for declining audience figures concerns sports that have moved from free-to-air broadcasters to pay television. In the UK, the transition of the British Open from the BBC to Sky television led to a 75% drop in viewing figures. The highlights package broadcast on the BBC following the conclusion of the event drew almost half a million more viewers than the live coverage on Sky. This suggests that short-run events (at least in the initial stages of the relationship), such as the Open might be insufficient to translate British Golf fans into Sky subscribers.

In Australia, Optus gained the rights to EPL by paying almost three times the amount Foxtel was paying to show it previously. This has been the subject of a large amount of fan anger ever since. Viewership through these channels is difficult to track, but Optus subscriptions do not appeared to have increased markedly since the deal. Meanwhile, ratings for the home-grown A-league, which airs on Fox Sports and SBS, are up, possibly because fans are switching from EPL for their soccer fix.

But the money being offered to move to pay TV is hard to turn down.

It looks like the next five year BBL rights could go for up to $A300 million – a three-fold increase from the A$100 million Ten paid for the initial five year deal. A big part of the BBL’s success has come from it being broadcast every night of the week, on a major free-to-air channel, at a relatively non-competitive time of year. Broadcast it on pay TV and things might change. Sure, some people will subscribe, but BBL is largely a family sport and the added subscription costs could price out a substantial proportion of the consumer market.

Still a golden opportunity for free TV

Restricted broadcast threatens the future of a sport league. All brands grow by increasing the number of people who consume them. Only free TV gives that to sports brands. The EPL story defies this logic, demonstrating exponential growth since its transition to Sky Sports in the early 90s; however, if brands choose to limit distribution to narrow channels like pay TV, the chances of brand growth are severely limited.

Advertisers and sponsors, already confused about where they should be advertising, are also big losers if sport isn’t shown on free-to-air TV. As Professor Mark Ritson explains quite colourfully, traditional media gets much better results than social media advertising and other alternatives. But to do so, it must have wide reach – it needs to be attracting large audiences. If free to air television was to lose big draw card sport broadcasts, audiences shrink and advertising there becomes much less powerful.

Whatever it costs to retain sports on FTV, it is probably worth it for both advertisers and broadcasters. And it’s not just the sports that are big right now that they should focus on. Australia’s appetite for sport is not diminishing, but it is reshaping.

A recent survey we conducted of 4,000 people Australia-wide showed that interest in the AFL women’s league (AFLW) is strong. Around two thirds of AFL fans will either watch or attend at least one game of AFLW during this upcoming season. Across all people surveyed, around 27% said they were likely to attend a game of AFLW and 38% intended to watch at least half a match on television. Even allowing for the usual difference between what people intend to do and what actually ends up happening, these numbers are strong. The AFL has wisely moved games to bigger venues in anticipation of much larger crowds than the initial 5,000 per match estimates.

AFLW stands a very good chance of being Australia’s dominant women’s sporting league – in its very first year. For a savvy broadcaster, this represents a golden opportunity.

New BU research magazine published

Cover image

The latest edition of the Bournemouth Research Chronicle (BRC) is now available.  The magazine shares just a small selection of the research taking place at BU, from working with local hospitals to shaping conservation practices in Indonesia to improving sports equipment.

Complex global challenges are a defining feature of today’s world and universities can play a key role in addressing these challenges.  Here at Bournemouth University, we encourage our researchers to work together with our students and external organisations – businesses, charities, and hospitals to name just a few – to find solutions to these issues.  We believe that by bringing together research, education and professional practice, we can make a real difference through our work.  We call this Fusion.

This edition shares some of our examples of Fusion in action.  You’ll discover how our academic community is working together to co-create solutions to global challenges and to better understand society and the world around us.  You can also read about some of our newly awarded research grants and projects being undertaken by some of our PhD students.

Our students are a key part of our academic community and are involved in a wide range of research projects at BU.  In this edition of the BRC, you can find out about their fieldwork in Indonesia, Nepal and Spain, where they have been able to develop skills and gain experiences which will enhance their employability and help them later on.  In Indonesia, our students have been working with local charities to improve conservation practices, while in Nepal, student journalists have been reporting on the aftermath of the 2015 earthquake.

Locally, our researchers are collaborating with partner organisations in the region to extend our impact and make a real difference.  One example is our work with the Royal Bournemouth Hospital, where staff, former patients and BU researchers have been exploring the idea of ‘humanised care’ and how this can improve patient experiences.

We also encourage and support our researchers to work alongside businesses and other external organisations, enabling them to create projects that provide new, innovative ideas and drive industries forward.  Just one of the ways we support this is through Higher Education Innovation Funding (HEIF), which allows us to support a wide range of knowledge-based interactions between universities and the wider world.  In this edition of the BRC, you can read about two of our newest HEIF projects and challenges that our researchers are tackling.

British Academy Flagship Skills Project – The value of Arts, Humanities and Social Sciences

british_academy_logoThe British Academy is launching an exciting new project which aims to articulate, for the first time, the skills that are inherent to the study of arts, humanities and social sciences (AHSS), their value to the individual, and the contribution they do make and could make in future to society.

Building on the success of its Languages and Quantitative Skills (LQS) Programme, the British Academy is developing a new programme of work on skills. The flagship project of this programme aims to articulate the skills that are inherent to the study of arts, humanities and social sciences (AHSS), their value to the individual, and the contribution they do make and could make in future to society as well as those that are important for educators of AHSS students to introduce directly. The Academy hopes to stimulate and facilitate a national debate about the nature and value of these skills, as well as setting the agenda for its own Skills Programme to 2020.

The project will seek to intellectualise what is meant by skills, and look at questions such as what skills should studying AHSS develop? What skills do individuals who have studied AHSS demonstrate? What contribution do individuals with AHSS skills make to society and the economy? What skills do employers want? What skills will be needed in the future
