description: We formulate a universal method for solving an arbitrary quantum system which, in the Bargmann representation, is described by a system of linear equations with one independent variable, such as one- and multi-photon Rabi models, or $N$ level systems interacting with a single mode of the electromagnetic field and their various generalizations. We explain three types of conditions that determine the spectrum and show their usage for two deformations of the Rabi model. We prove that the spectra of both models are just zeros of transcendental functions, which in one case are given explicitly in terms of confluent Heun functions.

description: Genome-wide association studies (GWAS) have identified many genetic factors underlying complex human traits. However, these factors have explained only a small fraction of these traits' genetic heritability. It is argued that many more genetic factors remain undiscovered. These genetic factors likely are weakly associated at the population level and sparsely distributed across the genome. In this paper, we adapt the recent innovations on Tukey's Higher Criticism (Tukey [The Higher Criticism (1976) Princeton Univ.]; Donoho and Jin [Ann. Statist. 32 (2004) 962-994]) to SNP-set analysis of GWAS, and develop a new theoretical framework in large-scale inference to assess the joint significance of such rare and weak effects for a quantitative trait. In the core of our theory is the so-called detection boundary, a curve in the two-dimensional phase space that quantifies the rarity and strength of genetic effects. Above the detection boundary, the overall effects of genetic factors are strong enough for reliable detection. Below the detection boundary, the genetic factors are simply too rare and too weak for reliable detection. We show that the HC-type methods are optimal in that they reliably yield detection once the parameters of the genetic effects fall above the detection boundary and that many commonly used SNP-set methods are suboptimal. The superior performance of the HC-type approach is demonstrated through simulations and the analysis of a GWAS data set of Crohn's disease.

description: This introduction presents the conceptual and analytical framework which constitutes the background for the special issue entitled ‘Varieties of Populism in Europe in Times of Crises’. More specifically, this contribution investigates how different populist parties in the European Union have been affected by the recent economic crisis and the more long-lasting political and cultural crises. Analytically, the article disentangles the role of the Great Recession vis-à-vis other factors (such as political and party system factors, but also structural social changes or cultural opportunities) in the growing strength of populist parties in various European countries. It argues that although the economic crisis has without any doubt provided a specific ‘window of opportunity’ for the emergence of new political actors, which have capitalised on citizens’ discontent, long-lasting political factors – such as the increasing distrust toward political institutions and parties – and the more recent cultural crisis connected with migration issues have offered further fertile ground for the consolidation of populist parties in several European countries. Furthermore, as confirmed by the articles presented in the special issue, the various crises have offered differential opportunities for different types of populism – both inclusionary and exclusionary.

description: The regional atmospheric model Consortium for Small-scale Modeling (COSMO) coupled to the Multi-Scale Chemistry Aerosol Transport model (Muscat) is extended in this work to represent aerosol-cloud interactions. Previously, only one-way interactions (scavenging of aerosol and in-cloud chemistry) and aerosol-radiation interactions were included in this model. The new version allows for a microphysical aerosol effect on clouds. For this, we use the optional two-moment cloud microphysical scheme in COSMO and the online-computed aerosol information for cloud condensation nuclei concentrations (Cccn), replacing the constant Cccn profile. In the radiation scheme, we have implemented a droplet-size-dependent cloud optical depth, allowing now for aerosol-cloud-radiation interactions. To evaluate the models with satellite data, the Cloud Feedback Model Intercomparison Project Observation Simulator Package (COSP) has been implemented. A case study has been carried out to understand the effects of the modifications, where the modified modeling system is applied over the European domain with a horizontal resolution of 0.25°g × g0.25°. To reduce the complexity in aerosol-cloud interactions, only warm-phase clouds are considered. We found that the online-coupled aerosol introduces significant changes for some cloud microphysical properties. The cloud effective radius shows an increase of 9.5g%, and the cloud droplet number concentration is reduced by 21.5g%.

description: Following up on earlier work, we investigate possible effects of a dressed quark-gluon vertex in heavy-light mesons. In particular, we study corrections to the popular rainbow-ladder truncation of the Dyson-Schwinger-Bethe-Salpeter equation system. We adopt a simple interaction kernel which reduces the resulting set of coupled integral equations to a set of coupled algebraic equations, which are solved numerically. In this way, we extend previous studies to quark-antiquark systems with unequal current-quark masses, at first for the pseudoscalar case, and investigate the resulting set of problems and solutions. We attempt to find patterns in - as well as to quantify corrections to - the rainbow-ladder truncation. In addition, we open this approach to phenomenological predictions of the heavy quark symmetry.

description: A significant body of work on simulating the remote appearance of Earth-like exoplanets has been done over the last decade. The research is driven by the prospect of characterizing habitable planets beyond the Solar System in the near future. In this work, I present a method to produce the disk-integrated signature of planets that are described in their three-dimensional complexity, i.e. with both horizontal and vertical variations in the optical properties of their envelopes. The approach is based on pre-conditioned backward Monte Carlo integration of the vector Radiative Transport Equation and yields the full Stokes vector for outgoing reflected radiation. The method is demonstrated through selected examples inspired by published work at wavelengths from the visible to the near infrared and terrestrial prescriptions of both cloud and surface albedo maps. A clear advantage of this approach is that its computational cost does not appear to be significantly affected by non-uniformities in the planet optical properties. Earth's simulated appearance is strongly dependent on wavelength; both brightness and polarisation undergo diurnal variations arising from changes in the planet cover, but polarisation yields a better insight into variations with phase angle. There is partial cancellation of the polarised signal from the northern and southern hemispheres so that the outgoing polarisation vector lies preferentially either in the plane parallel or perpendicular to the planet scattering plane, also for non-uniform cloud and albedo properties and various levels of absorption within the atmosphere. The evaluation of circular polarisation is challenging; a number of one-photon experiments of 1E9 or more is needed to resolve hemispherically-integrated degrees of circular polarisation of a few times 1E-5. Last, I introduce brightness curves...

description:
To improve chances of survival and response to treatment for life-threatening chronic diseases like cancer, detection of the early disease state is essential. MRI is the most beneficial imaging modality but due to the low sensitivity of current contrast agents, its capability for diagnosis is limited. Dr. Jenny Yangs group has developed a novel protein-based MRI contrast agent with collagen- and HER2-targeting moieties, hProCA32.collagen1 and hProCA32.HER2, exhibiting high relaxivity, and improved sensitivity and specificity. The focus of this thesis is the optimization of hProCA32 purification by the addition of a refolding step, pH adjustment, and pre-loading of Gd3+, to yield ~90% monomer of a pure hProCA32.collagen1. The purified hProCA32.collagen1 was found to exhibit good collagen-binding affinity (1.8 M) and high relaxivity (30.4 mM-1s-1 and 43.0 mM-1s-1 for r1 and r2) thereby suggesting that the MRI contrast agent may be useful to diagnose cancers at an early stage.

description: The zinc finger of the cerebellum (Zic) genes encode a family of transcriptional regulators critical for early embryogenesis. All ZIC proteins contain a zinc finger domain (ZFD) and other evolutionary conserved regions. They are pleiotropic in nature since they can influence gene expression directly by acting as transcription factors due to their ability to bind target DNA sequences, or indirectly as co-factors by interacting with protein partners. Little is known, however, about the structural components that allow ZIC proteins to perform these functions. Among ZIC family members the protein structure of ZIC3 is relatively well characterised, yet details regarding its transactivation domain remain unknown. During embryonic development ZIC3 is involved in maintaining pluripotency of embryonic stem cells, formation of the left-right (L-R) axis and arrangement of visceral organs. Mutations in Zic3 in humans and animal models cause congenital L-R axis defects. The work presented in this thesis maps structural domains required for ZIC3 molecular function. Characterisation of a novel allele of murine Zic3 revealed that removal of the ZFD and C-terminus renders the mutant protein functionally null and incapable of dominantly interfering with the function of other ZIC proteins. To further assess the transcription factor function of ZIC3, a new cell-based transactivation assay system using target ZIC3-DNA binding sequences was designed. This assay was used to identify regions within the ZFD and C-terminus vital for transactivation via ZIC3. In addition other evolutionary conserved domains were implicated in transactivation. This study provides a reliable and robust platform to investigate the transcription factor function of ZIC proteins and their variants.

description: Poverty maps are used to aid important political decisions such as allocation of development funds by governments and international organizations. Those decisions should be based on the most accurate poverty figures. However, often reliable poverty figures are not available at fine geographical levels or for particular risk population subgroups due to the sample size limitation of current national surveys. These surveys cannot cover adequately all the desired areas or population subgroups and, therefore, models relating the different areas are needed to 'borrow strength" from area to area. In particular, the Spanish Survey on Income and Living Conditions (SILC) produces national poverty estimates but cannot provide poverty estimates by Spanish provinces due to the poor precision of direct estimates, which use only the province specific data. It also raises the ethical question of whether poverty is more severe for women than for men in a given province. We develop a hierarchical Bayes (HB) approach for poverty mapping in Spanish provinces by gender that overcomes the small province sample size problem of the SILC. The proposed approach has a wide scope of application because it can be used to estimate general nonlinear parameters. We use a Bayesian version of the nested error regression model in which Markov chain Monte Carlo procedures and the convergence monitoring therein are avoided. A simulation study reveals good frequentist properties of the HB approach. The resulting poverty maps indicate that poverty, both in frequency and intensity, is localized mostly in the southern and western provinces and it is more acute for women than for men in most of the provinces.

description: We use theoretical analysis and numerical simulation to investigate the operation of a laser oscillating from gain supplied by stimulated Brillouin scattering (SBS) in a microresonator. The interaction of the forward, backward, and density waves within the microresonator results in a set of coupled-mode equations describing both the laser's phase and amplitude evolution over time. Using this coupled-mode formalism, we investigate the performance of the SBS laser under noise perturbation and identify the fundamental parameters and their optimization to enable low-noise SBS operation. The intrinsic laser linewidth, which is primarily limited by incoherent thermal occupation of the density wave, can be of order hertz or below. Our analysis also determines the SBS laser's relaxation oscillation, which results from the coupling between the optical and density waves, and appears as a resonance in both the phase and amplitude quadratures. We further explore contributions of the pump noise to the SBS laser's performance, which we find under most circumstances to increase the SBS laser noise beyond its fundamental limits. By tightly stabilizing the pump laser onto the microcavity resonance, the transfer of pump noise is significantly reduced. Our analysis is both supported and extended through numerical simulations of the SBS laser.

Fast and Simple Method for Pricing Exotic Options using Gauss-Hermite Quadrature on a Cubic Spline Interpolation

description: There is a vast literature on numerical valuation of exotic options using Monte Carlo, binomial and trinomial trees, and finite difference methods. When transition density of the underlying asset or its moments are known in closed form, it can be convenient and more efficient to utilize direct integration methods to calculate the required option price expectations in a backward time-stepping algorithm. This paper presents a simple, robust and efficient algorithm that can be applied for pricing many exotic options by computing the expectations using Gauss-Hermite integration quadrature applied on a cubic spline interpolation. The algorithm is fully explicit but does not suffer the inherent instability of the explicit finite difference counterpart. A `free' bonus of the algorithm is that it already contains the function for fast and accurate interpolation of multiple solutions required by many discretely monitored path dependent options. For illustrations, we present examples of pricing a series of American options with either Bermudan or continuous exercise features, and a series of exotic path-dependent options of target accumulation redemption note (TARN). Results of the new method are compared with Monte Carlo and finite difference methods, including some of the most advanced or best known finite difference algorithms in the literature. The comparison shows that, despite its simplicity, the new method can rival with some of the best finite difference algorithms in accuracy and at the same time it is significantly faster. Virtually the same algorithm can be applied to price other path-dependent financial contracts such as Asian options and variable annuities.

description: In this work we develop an ordinary differential equations (ODE) model of physiological regulation of glycemia in type 1 diabetes mellitus (T1DM) patients in response to meals and intravenous insulin infusion. Unlike for the majority of existing mathematical models of glucose-insulin dynamics, parameters in our model are estimable from a relatively small number of noisy observations of plasma glucose and insulin concentrations. For estimation, we adopt the generalized smoothing estimation of nonlinear dynamic systems of Ramsay et al. [J. R. Stat. Soc. Ser. B Stat. Methodol. 69 (2007) 741-796]. In this framework, the ODE solution is approximated with a penalized spline, where the ODE model is incorporated in the penalty. We propose to optimize the generalized smoothing by using penalty weights that minimize the covariance penalties criterion (Efron [J. Amer. Statist. Assoc. 99 (2004) 619-642]). The covariance penalties criterion provides an estimate of the prediction error for nonlinear estimation rules resulting from nonlinear and/or nonhomogeneous ODE models, such as our model of glucose-insulin dynamics. We also propose to select the optimal number and location of knots for B-spline bases used to represent the ODE solution. The results of the small simulation study demonstrate advantages of optimized generalized smoothing in terms of smaller estimation errors for ODE parameters and smaller prediction errors for solutions of differential equations. Using the proposed approach to analyze the glucose and insulin concentration data in T1DM patients, we obtained good approximation of global glucose-insulin dynamics and physiologically meaningful parameter estimates.

description: Microbial migration towards a trichloroethene (TCE) dense non-aqueous phase liquid (DNAPL) could facilitate the bioaugmentation of TCE DNAPL source zones. This study characterized the motility of the Geobacter dechlorinators in a TCE to cisdichloroethene dechlorinating KB-1TM subculture. No chemotaxis towards or away from TCE was found using an agarose in-plug bridge method. A second experiment placed an inoculated aqueous layer on top of a sterile sand layer and showed that Geobacter migrated several centimeters in the sand layer in just $7$ days. A random motility coefficient for Geobacter in water of $0.24 \pm 0.02$ cm$^2$ day$^{-1}$ was fitted. A third experiment used a diffusion-cell setup with a $5.5$ cm central sand layer separating a DNAPL from an aqueous top layer as a model source zone to examine the effect of random motility on TCE DNAPL dissolution. With top layer inoculation, Geobacter quickly colonized the sand layer, thereby enhancing the initial TCE DNAPL dissolution flux. After $19$ days, the DNAPL dissolution enhancement was only $24\%$ lower than with an homogenous inoculation of the sand layer. A diffusion-motility model was developed to describe dechlorination and migration in the diffusion-cells. This model suggested that the fast colonization of the sand layer by Geobacter was due to the combination of random motility and growth on TCE.

The survey presented here was conducted in Greece and is objective was to evaluate the outcome of the supervised work experience by examining the views of undergraduate tourism and hospitality management students who completed their industrial placement period. Data were obtained through personal interviews and were of both qualitative and quantitative nature. The tentative results of the research, as described in this exploratory study, indicate some areas for concern and allows for conclusions to be drawn in relation to further improving and enhancing experiential learning.

description: We have investigated the wave dynamics of a vector field perturbation coupling to Einstein tensor in the four-dimensional Reissner-Nordström black hole spacetime. Our results show that besides the dependence on the coupling between the vector field and Einstein tensor, the wave dynamic equation of the vector field perturbation strongly depends on the parity of the perturbation itself, which is quite different from that of the usual vector field perturbation without the coupling in the four-dimensional spacetime. Moreover, we also find that the vector field perturbation with odd parity grows with exponential rate if the coupling strength is stronger than certain a critical value. However, the vector field perturbation with even parity always decays in the Reissner-Nordström black hole spacetime.

description: This thesis presents a spectroscopic study of the 7F0 ---t5D0 transition of Eu3+ in EuC13 ·6H2 0, which is used to evaluate the potential performance of a quantum com­ puting system implemented in EuCla·6H2 0 and, more generally, in stoichiometric rare earth crystals. EuC13 ·6H2 0 has one of the narrowest optical inhomogeneous linewidths of any solid but this linewidth is shown to be still much larger than that required for practical quantum computing in a rare earth crystal. To assess the possibility of reducing the linwidth, the contributions of isotopic impurities to both the optical linewidth and line structure were investigated, and ligand isotopes were identified as a major source of both inhomogeneous broadening and structure on the optical transition, suggesting that the linewidth could be substantially reduced by isotopi­ cally purifying EuC13 ·6H20. The effect of ligand isotopes on the optical lifetime and coherence time was also investigated. It was found that fully deuterating the crystal to EuC13·6D20 substantially improves both the lifetime and coherence time. The satellite lines formed in the optical spectrum of a rare earth crystal when it is doped with another rare earth are proposed as qubits. A crucial step in char­ acterising EuCla ·6H20 for quantum computing is associating these satellite lines in EuC13 ·6H2 0 with crystallographic sites. A new method for associating sites with lines, which works for low symmetry crystals such as EuC13·6H20, is presented. This method involves modelling the splitting of the ground state hyperfine levels caused by the magnetic dipole-dipole interaction between a Kramers dopant and the Eu3+ ion. Using this method, most of the outer satellite lines in rare earth doped EuCla·6H2 0 were assigned to crystallographic sites. It has been proposed that the electronic interactions between these satellite lines be used to enact two-qubit gates in a rare earth quantum computer. These interac­ tions were measured between a number of different satellite lines using a new two­ laser spectral holeburning technique. Interactions of up to 46.081±0.005 MHz were observed, and this was the first time that electronic interactions between weakly coupled rare earth ions had been measured. The two most common interactions identified between rare earth ions in solids are electric dipole-dipole and exchange, but the observed interactions are stronger than expected from a electric dipole-dipole model and occur at too large a distance to be superexchange. It is shown that the development of a moderate-sized quantum processor, one with more than 10 qubits, in a stoichiometric rare earth crystal is feasible provided that the optical inhomogeneous linewidth is reduced below 1MHz. Demonstrations of three or four qubit devices should be possible using existing materials.

description: A multi-physics formulation for Data Driven Prognosis (DDP) is developed. Unlike traditional predictive strategies that require controlled off-line measurements or training for determination of constitutive parameters to derive the transitional statistics, the proposed DDP algorithm relies solely on in situ measurements. It utilizes a deterministic mechanics framework, but the stochastic nature of the solution arises naturally from the underlying assumptions regarding the order of the conservation potential as well as the number of dimensions involved. The proposed DDP scheme is capable of predicting onset of instabilities. Since the need for off-line testing (or training) is obviated, it can be easily implemented for systems where such a priori testing is difficult or even impossible to conduct. The prognosis capability is demonstrated here via a balloon burst experiment where the instability is predicted utilizing only on-line visual observations. The DDP scheme never failed to predict the incipient failure, and no false positives were issued. The DDP algorithm is applicable to others types of datasets. Time horizons of DDP predictions can be adjusted by using memory over different time windows. Thus, a big dataset can be parsed in time to make a range of predictions over varying time horizons.

description: In May 2021, the World Health Organization (WHO) announced a new naming system for variants of SARS-CoV-2, the virus that causes COVID-19. This naming system uses letters of the Greek alphabet to identify variants otherwise demarcated by formal scientific terminology and names that reference geographic locations. The WHO recommended that these letter names be used by media outlets and national authorities, to counter the confusion and stigmatisation perceived to characterise communication previously. Yet uncertainty persisted as to the uptake of new names—and so too the realisation of intervention intentions. In the context of infectious disease outbreaks and beyond, history and existing literature emphasise the social significance of communication patterns and efforts to engender language change. Further, the communication constructs of naming and framing emerge as influential elements, as does news media communication as a medium. To characterise communication about SARS-CoV-2 variants at the time of the WHO intervention and in turn analyse the implications of associated change in terms of WHO intentions, a quantitative content analysis was conducted. The results demonstrate uptake of Greek letter names, but also nuances to that dynamic. Divergence in naming and framing patterns between media companies was identified, as was the potential for intended outcomes of de-stigmatisation and communication clarity to be compromised. These results highlight the susceptibility of the intervention to communication-mediated interference and highlight opportunities for the refinement of future naming (and renaming) efforts. This study also provides a foundation for future research into the effects of communication change on stigmatisation outcomes, and inquiry into the nature and nuances of science communication in news media coverage. Considering ongoing real-world developments, this study inspires further research into infectious disease naming and associated language change.

description: We present a viable method to obtain real-time quantities such as spectral functions or transport coefficients at finite temperature and density within a non-perturbative Functional Renormalization Group approach. Our method is based on a thermodynamically consistent truncation of the flow equations for 2-point functions with analytically continued frequency components in the originally Euclidean external momenta. We demonstrate its feasibility by calculating the mesonic spectral functions in the quark-meson model at different temperatures and quark chemical potentials, in particular around the critical endpoint in the phase diagram of the model.

“I know what thou arte”: Race and Nation in Thomas Malory’s Le Morte Darthur
Creators: name: Jin, Nancy
Publisher: name: The Australian National University

Subjects: King Arthur

medievalism

description: This thesis examines the ways in which new understandings of medieval texts may be generated using postcolonial frameworks and categories, especially by elucidating notions of race and nation in medieval texts. These discourses of race and nation are fundamental to the construction of identities in medieval texts, and seek to undermine the idea of the Middle Ages as Other to modernity. These chapters offer an exploration of the construction of race and nation in Thomas Malory’s Le Morte Darthur, and seek to demonstrate the fragile, contested nature of these categories. In Chapter 1 and Chapter 2, I give a reading of Malory’s depiction of the war between King Arthur and the Roman Emperor Lucius. I argue that notions of race and a national ‘imagined community’ are integral to the fantasy of unity which Malory is wedded to. Chapter 3 closely examines the Saracen knight Palomydes as a colonial subject and an Other within the Arthurian court.

description: We extend the results of arXiv:1401.1645 on the generalized conformal Sp(2n)-structure of infinite multiplets of higher spin fields, formulated in spaces with extra tensorial directions (hyperspaces), to the description of OSp(1|2n)-invariant infinite-dimensional higher-spin supermultiplets formulated in terms of scalar superfields on flat hyper-superspaces and on OSp(1|n) supergroup manifolds. We find generalized superconformal transformations relating the superfields and their equations of motion in flat hyper-superspace with those on the OSp(1|n) supermanifold. We then use these transformations to relate the two-, three- and four-point correlation functions of the scalar superfields on flat hyperspace, derived by requiring the OSp(1|2n) invariance of the correlators, to correlation functions on the OSp(1|n) group manifold. As a byproduct, for the simplest particular case of a conventional N=1, D=3 superconformal theory of scalar superfields, we also derive correlation functions of component fields of the scalar supermultiplet including those of auxiliary fields.

description: Religiosity is a powerful force shaping human societies, affecting domains as diverse as economic growth or the ability to cope with illness. As more religious leaders and organizations as well as believers start using social networking sites (e.g., Twitter, Facebook), online activities become important extensions to traditional religious rituals and practices. However, there has been lack of research on religiosity in online social networks. This paper takes a step toward the understanding of several important aspects of religiosity on Twitter, based on the analysis of more than 250k U.S. users who self-declared their religions/belief, including Atheism, Buddhism, Christianity, Hinduism, Islam, and Judaism. Specifically, (i) we examine the correlation of geographic distribution of religious people between Twitter and offline surveys. (ii) We analyze users' tweets and networks to identify discriminative features of each religious group, and explore supervised methods to identify believers of different religions. (iii) We study the linkage preference of different religious groups, and observe a strong preference of Twitter users connecting to others sharing the same religion.

description: BACKGROUND: Hepatitis C (HCV) infection has been rising in the suburban and rural USA, mainly via injection-based transmission. Injection and sexual networks are recognized as an important element in fostering and preventing risky behavior; however, the role of social support networks has received somewhat less attention. METHODS: Using baseline data from an ongoing longitudinal study, we examined the composition and structure of injection drug use (IDU), sex, and social support networks of young people who inject drugs (aged 18-30) and their injection network members. Lasso logistic regression was used to select a subset of network characteristics that were potentially important predictors of injection risk behaviors and HCV exposure. RESULTS: Several measures of IDU, sexual, and support network structure and composition were found to be associated with HCV exposure, receptive syringe sharing (RSS), and ancillary equipment sharing. Gender and sexual relationships were important factors for all risk behaviors. Support network characteristics were also important, notably including a protective effect of majority Hispanic support networks for RSS and HCV exposure. Both IDU network residence heterogeneity and support network geography were associated with injection equipment sharing. CONCLUSIONS: The associations of IDU and support network geography with equipment sharing highlight the need to extend harm reduction efforts beyond urban areas. Greater understanding of support network influences on risk behavior may provide important insights to strengthen the benefits of harm reduction. In considering the probability of HCV transmission, it is important to consider setting and network structures that promote propagation of risk.

One Health

description: The One Health EJP (OHEJP) Final “Summer” School 2022 “Sustainability in One Health – how can it be achieved?” was held from 5th to 7th December 2022. The event focused on sustainability, since it is at the core of the One Health approach to optimise the health of people, animals, plants, and ecosystems and needs to be at the centre of the training of young One Health scientists and practitioners. Sustainable solutions must be adopted that recognise the importance of animal welfare, biodiversity and ecosystem integrity for overall health and well-being, now and for future generations. This Final School was organised by the Local Organising team at University of Surrey in Guildford – UK, led by Roberto La Ragione (Professor of Veterinary Microbiology and Pathology at the School of Veterinary Medicine and Head of the School of Biosciences). The event was organised and hosted in collaboration with the OHEJP Work Package 6 (WP6) team and Communications team based at the University of Surrey, UK. The event was held online to reach a wider international audience. In total, over 200 scientists from countries across the globe participated. The event was a major success as it provided the first international training initiative entirely devoted to sustainability to a multidisciplinary audience of delegates and involved many OHEJP partners as well as OHEJP Stakeholders. The testimonials from the delegates provide telling evidence of the Final School success.

description: Aim The relation of plant dispersal syndromes with insular species richness patters remains one of the challenges in island biogeography, especially as people have affected species distribution patterns. This study disentangles how dispersal syndromes influence the relationship of richness with area and isolation while also accounting for the human impact on island biodiversity. It builds on the potential of islands at the mesoscale and of similar origin to contribute to the ongoing discussion in island biogeography on what determines species richness and filtering. Location Denmark, 54 islands in the North and Baltic Sea. Taxon Vascular plants, including pteridophytes. Methods Generalized linear models (GLMs) and linear regressions are used to analyse how dispersal syndromes influence the relationships of species numbers with island area and isolation, as well as island inhabitation and human density, respectively. Results Species numbers, seed mass and the proportion of zoochore and anemochore species are positively related to island area while the share of water-dispersed species decreases with increasing area. Isolation is weakly related to mean seed mass but has no explaining power for species numbers and the presence of specific dispersal syndrome on the target islands. Species richness and seed mass were positively related to human presence. Main conclusions Human impact for centuries has not overwritten the strong relationship of species richness with area on the Danish Islands but is affecting the shape of this relationship. Island area constitutes a strong filter for different dispersal syndromes and leads to the assumption that heavier and animal-dispersed seeds are positively related to area due to the presence of more bird and mammal species. Human-induced loss of isolation caused by ongoing traffic and the connection of landmasses by bridges and ferries may be a reason for the overall low explanatory power of island isolation.
