Raman spectroscopy as a novel non-invasive technique to assess wildlife welfare
Caitlin MacNeill
College of Health and Scienc
Chronic stress is a prominent issue for animal welfare because it can lead to long-term health issues. One method to assess animals long-term stress is to measure their hair cortisol concentrations (HCC). This non-invasive method gives an insight into the last few weeks to months of cortisol production. Current techniques to measure HCC include Immunoassays and Liquid chromatography-mass spectrometry (LC-MS), which is considered the gold standard in analysis. However, both of these methods have limitations. They are time-consuming, destructive, expensive, and LC-MS is impractical for field use. To combat these limitations, we propose using Raman spectroscopy as a rapid, cheaper, and non-destructive technique which also has in-situ applications, with the recent development of handheld devices. Raman works by irradiating the sample with a laser which causes molecular vibrations that scatter the light waves. The scattering is measured and produces spectra which are unique to specific molecules. Cortisol concentrations can be quantified by comparing the intensity of these spectra with known concentrations to create a calibration curve. Spectra from hair samples can be added to this calibration to determine the concentration of cortisol present within the hair matrix. These measures can then be validated by analysing the same hairs using LC-MS. Preliminary results have successfully created calibration curves of varying cortisol concentrations using both LC-MS and Raman. In future hair analysis using Raman, we expect overlapping signals from the hair matrix making it difficult to define cortisol concentrations using peak intensity alone. To minimise these effects, we intend to use multivariate analysis to remove all signals present that do not directly relate to cortisol. If successful, using Raman to monitor stress levels by hair analysis could greatly improve animal welfare by offering a rapid, in-situ detection method that may be applied to both wild and domesticated animals.
The Untold Story of Nomadic Education for Fulani Pastoralists in Northern Nigeria

An essential goal by most nation states in a World Conference held in 1990 in Jomtien, Thailand, and a vital tool for economic development (Imam, 2012). Nigeria has embraced this and developed a policy of providing universal basic education that includes the needs of its nomadic community. However, until recently literature has historically shown a postcolonial approach to the education needs of the masses, often excluding minority groups such as nomads that were in many respects represented as a ‘hard to reach’ group (Freire, 1970 and Dyer, 2014). For example, Carr-Hill and Peart found low school enrolment rates of pastoral nomads in a study of six East African countries (Carr-Hill & Peart, 2005). Indeed, past policies such as the ‘universal primary education’ in Nigeria, either excluded or fell short of the needs of the nomadic community. For instance, there are claims that prior education policies were designed to make nomads sedentary which is contrary to their way of life (Chatty, 2007). Other studies suggested that the English language of instruction provided Western influence that was frowned upon by the nomadic community (Akpan, 2015). Studies on nomadic education tend to be fragmented, offering ‘single stories’ instead of a wholistic picture. Research has yet to uncover other areas such as institutional challenges. Therefore, the thesis aims to offer a more complete representation of one nomadic group, that of the Fulani pastoralists and their relationship with education in northern Nigeria, uncovering various challenges and successes as a community. An indigenous methodological approach is taken, viewing emerging literature with postcolonial lens, while taking a communitarian and participatory approach when collecting primary data from focus groups of nomadic pastoralists. The outcome should contribute to improved policy making for their education.
Structure, functional and physicochemical properties of starch and protein from two runner beans (Phaseolus coccineus) varieties

The growing human population and the impact of animal protein consumption on carbon footprints has increased the demand for plant-based foods by health-conscious consumers and the food industry. Neglected and underutilised crops such as runner bean are considered future food security crops that could be used to deliver value-added ingredients in the food industry. The underutilisation of many pulses including runner bean may be associated with the difficulty in cooking, high level of antinutrients and limited research to unlock their potentials. Runner bean is a starchy grain that contains relatively high protein (18.93 – 23.80%) and appreciable amounts of glutamic acid when compared to other pulses.
The starch and protein in runner bean represent valuable ingredients for the UK food and drink industry. For example, the starch could be modified and used as a thickening agent, while the protein hydrolysate and peptide fractions may be potentially used as ingredients in the formulation of functional foods and nutraceuticals against high blood pressure and oxidative stress. To enhance the use of runner bean grown in Europe including the UK as a food and industrial crop, a knowledge of their major components such as starch and protein is important. Hence, the aim of this research is to determine the structure, functional and physicochemical properties of starch and protein from two runner bean varieties (scarlet and white) using established methods.
A preliminary study on the colour parameters (L*= Lightness, -a*= greenness, +b* = yellowness) of the runner bean variant showed significant differences in their L* values (white = 84.98; scarlet = 31.04). This may be associated with the differences in their grain coat colour. This study is expected to unravel the potential of runner bean protein and starch isolates for food and industrial applications.
Creative Limitations, Problem Solving And The Cinematographers Role In Tackling Climate Change
Jack Shelbourn
College of Arts, Social Sciences and Humanities
Film and television, through its history, has always been riddled with limitations. Be it the length of a film reel, the time the sun sets and the processing power of a CPU. As with many art forms, the artists behind film and television must make a choice. Allow these limitations to hamper creativity and bend to their will. Or find a way to use these limitations to enhance creativity and perhaps even make something better than originally intended.

Strength and Conditioning Practices of National Hockey League Strength and Conditioning Coaches and Sport Scientists

College of Health and Science
The purpose of this study was to provide an in-depth review of the current practices of strength and conditioning (S&C) coaches and sport scientists in the NHL and evaluate the new technology, exercises, and training methods being used. A survey was emailed to all 32 NHL S&C coaches and sport scientists/performance directors covering six main areas: Personnel Information, Physical Testing, In-season, Off-Season, Program Design, and Technology. The response rate was 62.5% (20/32). Ninety-five percent of teams had a head S&C coach, 85% had an assistant S&C coach, 50% had a performance director and 50% had a sport scientist. The most frequently assessed fitness variables were body composition (100%), power (95%), strength (80%), and dry-land anaerobic capacity (70%). All teams reported using a periodization model in the off-season, while only half used such an approach in-season. The most common types of technology used were heart rate monitors (100%), force plates/jump mats (95%), bar velocity tracking units (80%), Local Positioning System/inertial measurement units (70%), and the 1080 sprint (55%). The results of show an expansion in the personnel of NHL performance departments and extensive testing protocols with a high reliance on technology. This study serves as an in-depth review of the current practices of S&C coaches in the NHL, the new technology being used, and the new training methods being employed. This data can help guide S&C coaches on what practices and technology are being used at the highest level in ice hockey and provide a possible source for new ideas.
