SUPERSEDED - Evaluation of impact of assessment changes on REDU11046
No full text## This item has been replaced by the one which can be found at https://doi.org/10.7488/ds/7778 ##This dataset relates to a case study which evaluated the introduction of concept maps (CM) as a learning activity and assessment task on a 10 credit (ECTS 5 credits) social science research methods course at SCQF level 11 (taught postgraduate level). The course runs for five weeks in semester one and over the previous five years student enrolment has been between 575 and 971. Most (>90%) students have English as a second or other language (ESOL) and many are new to studying social sciences. The CM was introduced to allow students to focus on developing their conceptual understanding rather than their academic writing skills. The data set includes interview schedules used and the secondary data (course marks) analyse
Network structure and taxonomic composition of tritrophic communities of Fagaceae, cynipid gallwasps and parasitoids in Sichuan, China
No full textA key question in insect community ecology is whether parasitoid assemblages are structured by the food plants of their herbivore hosts.
Tritrophic communities centred on oak-feeding cynipid gallwasps are one of the best-studied tritrophic insect communities. Previous work suggests that host plant identity is a much stronger predictor of oak-cynipid interactions than of cynipid-parasitoid interactions. However, these relationships have not been formally quantified.
We reason that the potential for ‘bottom-up’ effects should increase with host plant phylogenetic diversity. We therefore generated quantified interaction network data for previously unstudied tritrophic cynipid communities in Sichuan, China, where, in addition to Quercus, cynipid host plants include Castanea, Castanopsis and Lithocarpus. We characterise these communities taxonomically, and compare the extent to which host plant taxonomy predicts plant-herbivore and plant-parasitoid associations.
We sampled 42,620 cynipid galls of 176 morphotypes from 23 host plant species, yielding over 4500 specimens of 64 parasitoid morphospecies. Many parasitoids were identifiable to chalcidoid taxa present in other Holarctic oak cynipid communities, with the addition of Cynipencyrtus (Cynipencyrtidae). As elsewhere, Sichuan parasitoid assemblages were dominated by generalists.
Gallwasp-plant interaction networks were significantly more modular than parasitoid-plant association networks. Gallwasps were significantly more specialised to host plants (i.e. had higher mean d’ values) than parasitoids. Parasitoid assemblages nevertheless showed significant plant-associated beta diversity, with a dominant turnover component.
We summarise parallels between our study and other Fagaceae-associated cynipid communities, and discuss our findings in light of the processes thought to structure tritrophic interactions centred on endophytic insect herbivores.Readme.doc

The documents uploaded here are referenced in the publication Collins, R. And J. Linsley, Sonic Detection: A Polygraph (Santa Barbara, CA: punctum books). This phase of the project has been financed by Royal Society of Edinburgh (grant ID. 1076). Early phases of the project received funding from Arts Council England (grant ID. 31424873), Aberdeen University with Aberdeen City Council for the Silver City Stories Festival (grant ID. MB16). A set of physical documents related to this submission are housed at the Theatre Collection at the University of Bristol. Value for the public can be found in the connection of materials gathered in distinct locations on the coast of the UK (Bournemouth, Felixstowe, Seaham in County Durham and Aberdeen) which collectively speak to contemporary politics in the UK. The aesthetic and creative potential of the data, its focus on sound and listening at specific points between 2014-2019 (pre-Brexit) speak to a particular time in the history of the UK and its relationship to Europe. The files are grouped according to geographic location which documents the “on-the-ground” fieldwork with a selection of materials related to the “Stolen Voices” investigation and consist of audio files, stored in a .WAV format, video files stored in .MPEG format and .docx or .pdf text files. A further set of materials relate to research seminars and pedagogical uses of the research. A final set are rehearsal materials from live performances which were performed under the title of “Her Figure a Song”.See readme_07_02_24.txt fil

Synthesised histogram of photon counts
Get PDFThe structure of the input data in the demo code of “demo.m” is a synthesised histogram of photon counts in a time-resolved fluorescence sensing and or imaging system. A histogram is generated randomly from one of the six deterministic fluorescence life signal (including growth and decay phases) perturbed by a random component, including shot noise (Poissonian noise) and background Gaussian noise. For real experimental data, the user of the codes can feed an actual histogram to the algorithm of fit-flexible approach.Fore description, please read the Word file of "User_guide" inside
Harnessing Cosmic Carbon: Anaerobic Microbial Responses to Fullerenes Under Early Earth Conditions
No full textFullerenes of extra-terrestrial origin may have been accessible as a carbon source for anaerobic microorganisms on the early Earth. Very little is known about how microorganisms respond to and utilise fullerenes and their soluble derivatives, particularly in anoxic environments. We present an investigation into the effects of fullerenes C60 and C70 and their hydroxylated fullerol derivatives on an environmentally relevant anaerobic community and a microbial isolate. Anaerobic microorganisms were cultured in microcosms with suspensions of fullerenes with and without supplementary carbon under different levels of light exposure. Relevant early Earth environmental conditions were simulated by irradiating fullerene suspensions with 254nm UV light for two weeks in the absence of oxygen and the accessibility of the photodegradation products was assessed. We find that the anaerobic community is capable of utilising C60 as a sole carbon source, but that C70 is inhibitory. Additionally, we find that both C60 and C70 fullerol are inhibitory to the anaerobes in this study, which is contradictory to previous studies conducted under aerobic conditions. The anaerobic isolate was unable to grow on C60 alone, but after UV exposure, the C60 photodegradation products served as a highly accessible carbon source. Thus, we present a report on the utilisation of photodegraded C60 as the sole carbon source by an anaerobic microorganism under anoxic conditions. Further data shows that fullerenes and their derivatives can both enhance and inhibit the growth of anaerobic microorganisms, which has important implications for their interactions with early life on Earth and their impact on anoxic environments as pollutants in the present day
Causes of Variation in Malaria Infection Dynamics: Insights from Theory and Data
Get PDFAbstract
Parasite strategies for exploiting host resources are key determinants of disease severity (i.e., virulence) and infectiousness (i.e., transmission between hosts). By iterating the development of theory and empirical tests, we investigated whether variation in parasite traits across two genetically distinct clones of the rodent malaria parasite, Plasmodium chabaudi, explains differences in within-host infection dynamics and virulence. First, we experimentally tested key predictions of our earlier modeling work. As predicted, the more virulent genotype produced more progeny parasites per infected cell (burst size), but in contrast to predictions, invasion rates of red blood cells (RBCs) did not differ between the genotypes studied. Second, we further developed theory by confronting our earlier model with these new data, testing a new set of models that incorporate more biological realism, and developing novel theoretical tools for identifying differences between parasite genotypes. Overall, we found robust evidence that differences in burst sizes contribute to variation in dynamics and that differential interactions between parasites and host immune responses also play a role. In contrast to previous work, our model predicts that RBC age structure is not important for explaining dynamics. Integrating theory and empirical tests is a potentially powerful way of progressing understanding of disease biology.

ECOARM clinical study

Graphene oxide nanomaterials are being developed for wide-ranging applications, but have potential safety concerns for human health. We conducted a double-blind randomised controlled study to determine how inhalation of graphene oxide nanosheets affects acute pulmonary and cardiovascular function. Small and ultrasmall graphene oxide nanosheets at µg/m3 or filtered air were inhaled for 2 hours by 14 young healthy volunteers on repeated visits. Overall, graphene oxide nanosheet exposure was well-tolerated with no adverse effects. Heart rate, blood pressure, lung function and inflammatory markers were unaffected irrespective of graphene oxide particle size. Highly enriched blood proteomics analysis revealed very few differential plasma proteins and thrombus formation was mildly increased in an ex vivo model of arterial injury. Overall, acute inhalation of such highly purified and thin graphene oxide nanosheets of nanometre dimensions was not associated with overt detrimental effects in healthy humans. These findings demonstrate the feasibility of carefully controlled human exposures for risk assessment of graphene oxide, and lay the foundations for investigating the effects of other two dimensional nanomaterials in humans
Grounding line and ice speed tracking vectors for Totten Ice Shelf
No full textThis dataset contains:
1) Shapefiles of the mapped grounding line location from Landsat imagery in 1973, 1989, 2000 and 2023 for parts of Totten Glacier.
2) Shapefiles of the tracked feature used to calculate ice speed anomalies on Totten Ice Shelf.
This dataset is related to the manuscript 'Totten Ice Shelf history over the past century interpreted from satellite imagery' that has been submitted to The Cryosphere.
Totten Glacier is currently the largest source of mass loss in the East Antarctic Ice Sheet and it is projected to be a large source of sea-level rise over the coming century. The glacier has been losing mass for decades and inland thinning was detected in the earliest satellite-altimetry observations in the early-1990s, but when the glacier first started losing mass remains unknown. We calculate decadal ice-speed anomalies to confirm that Totten Glacier has not accelerated since at least 1973. Together with observations of grounding-line retreat from 1973-1989, we confirm that the glacier was already out of balance in the 1970s. Surface undulations form on the Totten Ice Shelf adjacent to an ice rumple near the grounding line in response to time-varying melt rates and are preserved downstream for several decades. From utilizing the full suite of Landsat imagery, we produce a century-long record of surface-undulation formation that we interpret as a qualitative record of basal-melt-rate variability. An anomalous ~20-year absence of undulations associated with the mid-20th century reveals a period when ice passing over the ice rumple was pervasively thinner, and may represent an anonymously warm period that triggered the onset of modern-day mass loss at Totten Glacier. We conclude that the short ~30 year satellite altimetry records are not long enough to capture the full scale of decadal variability in basal-melt rates.All files are shapefiles (*.shp) and accompanying files (*.shx, *.cpg, *.dbf. *.sbn
