    The output is an exhibition of paintings and drawings representing two contrasting environments. Together, these works seek to explore the potential for re-presentation to provoke new readings of place. The notion of ‘double vision’ examines the differences between space and place, the phenomenological (bodily and perceptual) experience of place, and the relationship between place and its re-emplacement through drawing and painting. Research Process: In gallery one there were graphite drawings presenting recently cultivated agricultural edge lands, made through the iterative layering of marks. They were made after extensive visits to site, documenting these visits through sketches and photographs. These pieces collectively entitled ‘Noema’ reference Husserl’s ideas on judgement, sense and meaning through the act of perception (1913). In relation to this, these drawings sought to investigate the real and perceived experience of being on site and making the work, with the perception of the work as both medium and image. In gallery two there were paintings of the Merrion Centre, a Brutalist inspired 1960s shopping precinct in Leeds. The Centre was of special cultural interest as the site of the first official synagogue in Leeds, opened in 1846 (Fraser, 2019). The paintings act to triangulate, archival research in the Centre (TCS archive), online forums and site visits with theoretical discourses regarding place, representation and memory. Research Insights: The findings of this research suggest that such places are ‘anthropological place’ (Auge, 2008). a multi-layered palimpsest of past and present constructed by those that inhabit them. Furthermore, it is suggested that through painting place, paintings can become “a place of presentation for this world” (Casey,2002). Dissemination: The research was disseminated through the exhibition at the Studio One Gallery, London, 2 – 11 March 2018

    The Eagle has Landed: Winter Eagle Research Takes Flight in the Bitterrroot Valley

    We began capturing Golden Eagles on the MPG Ranch in the Bitterroot Valley in 2011. Though we began with the intent of using satellite transmitters to learn about the habitat use and migration paths of adult, overwintering Golden Eagles, our research has evolved to encompass placing auxiliary markers on Golden and Bald Eagles of all ages. We also test eagles for environmental contaminants. So far we have captured and marked more than 75 Golden and 20 Bald Eagles. Due to these markers, we've amassed an impressive archive of eagle re-sightings in the Bitterroot Valley and other locations, including Washington and British Columbia. We've also learned that the majority of eagles captured show signs of lead exposure, likely from the ingestion of lead ammunition fragments. This year, we expanded efforts to study wintering eagles throughout the Bitterroot Valley. We've joined forces with Bitterroot Audubon and private landowners to set out carcass and camera stations on private lands throughout the valley. These efforts should increase the likelihood of re-encountering our marked eagles, demonstrate the value of private lands to eagles and other scavengers, and engage people from a variety of backgrounds with our research. We will share preliminary results from this collaboration, including impressive camera “captures” of Bald Eagles, Golden Eagles, and other scavengers. We will also share information about the public platform we are using to crowd-source image identification; this platform is available for other camera-trapping projects in Montana

    Investigating lineout performance between the top and bottom four English Premiership rugby union teams in the 2016/17 season

    This study investigated lineout performance between the top and bottom four English Premiership rugby union teams during the 2016/17 season. A season long review was conducted analysing all of the top four (n = 1152) and bottom four teams’ (n = 1124) lineouts. Findings showed the number of tries scored originating from a lineout play for the top four teams’ (1.57 tries per match) was higher in comparison to the bottom four teams’ (1.10 tries per match) (p .05). However, the top four teams were more effective in stealing opposition possession at a lineout (17%) compared to the bottom four teams (9%, p < .05). Additionally, top four teams showed a more forwards orientated style of play using binding actions (top = 62%, bottom = 56%, p < .05) and maul formation (top = 55%, bottom = 47%, p < .05). These results suggest coaches should focus on analysis of opposition tactics in lineout play in an aim to develop effective strategies to steal opposition possession at a lineout

    Three-dimensional fabrication of functional single crystal waveguides inside glass by femtosecond laser irradiation

    Ultrafast femtosecond (fs) pulsed lasers are capable of inducing a wide range of local structural modifications inside transparent materials, enabling direct three dimensional (3D) patterning of features inside monolithic samples. As such, direct laser-writing of waveguides, gratings, and other optical components has attracted considerable interest for the purpose of 3D optical integration. Much progress has been made in writing index-gradient waveguides in glass, but such amorphous waveguides are inherently passive structures. For the important class of active optics applications that require a second-order nonlinear optical response, glasses are fundamentally unsuitable due to their isotropically disordered structure. Bulk single crystals of non-centrosymmetric phases are typically used when such functionality is needed, but by choosing specific glass compositions which crystallize into these phases, nonlinear optical properties may be introduced locally into a glass through laser-induced crystallization. In this dissertation, major issues of practical and theoretical importance for fs laser crystallization are examined in the model LaBGeO5 glass system–including focal depth effects, nucleation mechanisms, growth dynamics, and obtained morphologies–in order to develop a model framework that guides the optimization of process parameters for obtaining high quality single crystal waveguides with functional capability. Initiation of new crystals from bulk glass in this strongly glass-forming system involves a complex multi-step process with a strong sensitivity to focal depth. The key mechanism is identified as a reliance on heterogeneous nucleation to increase the nucleation rate to practical laboratory timescales, which is facilitated by the formation of free surface in the form of bubbles and the local composition modification induced by the laser heating. The role of focal depth is to modulate the heat source geometry through optical aberration and thereby influence the geometry of the melt, the bubble distribution, and the element redistribution. The convergence of local composition and local temperature at the bubble surface ultimately determines the nucleation rate, so focal depth may be used as a process parameter to accelerate crystallization.If consistent heating conditions are desired at different focal depths, which would generally be the case for 3D fabrication, aberration effects are detrimental. A novel method is described for correcting aberration effects when irradiating through multiple refracting layers in order to produce consistent focal conditions at arbitrary focal depths inside externally heated samples inside a closed furnace. This enables simultaneous aberration correction and in-situ annealing, which is essential for the suppression of cracks.Patterning of continuous crystal features like waveguides requires scanning the focus through the glass. Counterintuitively, a preferential and seemingly consistent lattice orientation with respect to the scan direction is found to be associated with polycrystallinity rather than single-crystallinity, as has generally been thought. Rather, the retention of preferential orientation even across changes in scan direction arises from directional filtering and competitive maximization of growth rate between grains of multiple orientations, of which new instances are frequently attempted at the growth front. Crystal lines exhibiting preferential orientation may thus contain many similarly-oriented but distinct grains separated by low-angle grain boundaries, and these would generally be overlooked by low angular resolution optical methods of assessment.Nevertheless, irradiation conditions which are capable of suppressing this polycrystallinity are identified and explained in terms of the collective interactions between the laser-induced temperature gradient, the focal scan rate, the intrinsic temperature and orientation dependences of crystal growth rate, and the tendency of the growth front to initiate competing grains. Single crystallinity of lines written under these conditions is confirmed by high resolution electron backscatter diffraction, and a model of the dynamics of fs laser-induced single-crystal growth is presented. Finally, the waveguiding capability of fs laser-written single crystal lines inside a glass is demonstrated and quantified for the first time. A substantial power transmission is obtained in the case of the waveguide with the most consistent long-range uniformity. This confirms the potential applicability of the technique for writing nonlinear optical crystal waveguides, which until now has been largely hypothetical. This work thus provides the proof-of-concept for three dimensional fabrication of functional single-crystal waveguides inside glass

    The impact of COVID-19 through the eyes of a fourth-year pharmacy student

    © 2020 American Association of Colleges of Pharmacy. This commentary, written primarily by a recent pharmacy graduate, discusses the impact of COVID-19 on the class of 2020. Everyone has been impacted by COVID-19, but pharmacy students have been affected by and experienced COVID-19 in unique ways. This was the first class to complete pharmacy practice experiences in an online format, miss out on milestone events including graduation, and face uncertainty about becoming licensed and entering the job market in the midst of a pandemic. However, instead of discouraging them, these events have in many ways strengthened the resilience of the class of 2020. Additionally, COVID-19 has highlighted the importance of continued advocacy for the profession and articulation of the pharmacist’s expanded role and value to the health care team, and inspired the class of 2020 to join the ranks of colleagues nationwide in raising awareness in these areas. Nevertheless, uncertainty over their future and that of their peers lingers as COVID-19 has forever changed pharmacy education and practice

    Practice research encompasses diverse disciplines and outputs beyond traditional text-based scholarly work. However, existing infrastructure often overlooks the nuances of practice research, hindering its discoverability and reuse. This article summarizes findings from the Arts and Humanities Research Council-funded Practice Research Voices project, which aimed to scope recommendations for enabling practice research across repositories, metadata standards, and community engagement. We present key challenges facing practice research infrastructure, including the complexity of representing iterative, multi-component outputs. Drawing on repository development at the University of Westminster, we propose the ‘portfolio’ concept to aggregate objects and overlay narrative context. We also describe opportunities to evolve standards such as DataCite, RAiD, and CRediT to better accommodate practice research needs, and the value of a cross-domain community of practice. Our recommendations emphasize co-design with researchers and recognizing diverse forms of knowledge creation. Improving discovery and interoperability for practice research will require culture change across the scholarly infrastructure landscape. This project demonstrates that lessons learned from practice disciplines can benefit research more broadly through inclusive and flexible systems
