title: Performing Young Womanhood in Neoliberal Britain: Discursive Constructions of New Femininities
Creators: name: Paludan, Marie
Publisher: name: The Open University
Year: 2017

description: This thesis explores how young women negotiate the meanings and dilemmas of young womanhood in Britain today. Gender, womanhood and young adulthood have been variably defined and understood. This thesis will investigate how young women negotiate contemporary discursive constructions of femininity, taking a broadly social constructionist and discursive psychological perspective which conceptualises identities as constructed and continually negotiated in talk and interactions. The thesis analyses data from 13 semi-structured interviews with 8 female university students between the ages of 18 and 23. In addition, it analyses a data set of vlogs uploaded by 11 female vloggers in the same age group. In this thesis ‘discourse’ is used in the wider sense of denoting meaning-making practices such as visual images and appearance as well as spoken language. An innovative methodological framework for analysing video material is proposed. The thesis considers what kind of young woman is brought into being through the talk, appearances and other discursive practices of the participants. It shows how the participants negotiate complicated discursive contexts in which positioning oneself as empowered is desirable, and positioning oneself as a victim is undesirable. The thesis also shows how the participants position themselves as responsible in their talk about their futures. The analysis shows the ambiguities in young women’s orientations to their bodies, and the ways that young women position themselves as intelligent and mature by distancing themselves from vulnerability to beauty related pressures. The analysis also shows how young women continually work on improving themselves, reflecting not only on their self-improvements, but also on their ongoing reflexivity. Yet overdoing their careful controlling of themselves is constructed as unhealthy. The implications of these findings and the methods used are discussed.

description: In this letter, we show that upper-limits on neutrino mass translate into upper-limits on the class of neutrino-matter interactions that can generate loop corrections to the neutrino mass matrix. We apply our results to $μ$- and $π$-decays and derive model-independent limits on six of the ten parameters used to parametrize contributions to $μ$-decay that do not belong to the standard model. These upper-limits provide improved constraints on the five Michel parameters, $ρ,ξ^\prime,ξ^{\prime\prime},α,α^\prime$, that exceed PDG constraints by at least one order of magnitude. For $π^0\to ν\barν$ we find for the branching ratio: $B(π^0\toν\barν) < 10^{-10}$.

description: We report on magnetic and electrical transport properties of Sb2-xCrxTe3 single crystals with 0 <= x <= 0.095 over temperatures from 2 K to 300 K. A ferromagnetic state develops in these crystals at low temperatures with Curie temperatures that are proportional to x (for x > 0.014), attaining a maximum value of 20 K for x = 0.095. Hysteresis below TC for applied field parallel to the c-axis is observed in both magnetization and Hall effect measurements. Magnetic as well as transport data indicate that Cr takes the 3+ (3d3) valence state, substituting for antimony in the host lattice structure, and does not significantly affect the background hole concentration. Analysis of the anomalous Hall effect reveals that skew scattering is responsible for its presence. These results broaden the scope of ferromagnetism in the V2-VI3 diluted magnetic semiconductors (DMS) and in ferromagnetic DMS structures generally

description: A (v,0)-semilattice is ultraboolean, if it is a directed union of finite Boolean (v,0)-semilattices. We prove that every distributive (v,0)-semilattice is a retract of some ultraboolean (v,0)-semilattices. This is established by proving that every finite distributive (v,0)-semilattice is a retract of some finite Boolean (v,0)-semilattice, and this in a functorial way. This result is, in turn, obtained as a particular case of a category-theoretical result that gives sufficient conditions, for a functor $ Pi$, to admit a right inverse. The particular functor $ Pi$ used for the abovementioned result about ultraboolean semilattices has neither a right nor a left adjoint.

description: Kelly's criterion is a betting strategy that maximizes the long term growth rate, but which is known to be risky. Here, we find optimal betting strategies that gives the highest capital growth rate while keeping a certain low value of risky fluctuations. We then analyze the trade-off between the average and the fluctuations of the growth rate, in models of horse races, first for two horses then for an arbitrary number of horses, and for uncorrelated or correlated races. We find an analog of a phase transition with a coexistence between two optimal strategies, where one has risk and the other one does not. The above trade-off is also embodied in a general bound on the average growth rate, similar to thermodynamic uncertainty relations. We also prove mathematically the absence of other phase transitions between Kelly's point and the risk free strategy.

description: The ECS Data Management Plan (DMP) is Deliverable 1.2 (D1.2) from the EU-funded project European Citizen Science, grant agreement (GA) nr. 101058509. This deliverable introduces the first version of the DMP. The DMP describes the types of data that will be generated or collected during the project, the way in which the ECS consortium will manage the datasets that will emerge from the project (what datasets the consortium is aiming to preserve and in which format), and how best practice in terms of metadata and archiving will be used to ensure that the data will be findable, accessible, interoperable, and reusable (FAIR) for other potential users. Such users include researchers and practitioners in the field of citizen science, as well as any other interested party.

The DMP is a living document and the datasets referred to in this document are drafted during the first project stages. This document thus reflects the project partners’ initial plans toward developing the overall project’s datasets. The DMP will see updates elaborating on the collected datasets, as well as reflecting changes in the project. 

The leading frameworks for data management in ECS are the GDPR to protect personal data and the FAIR principles to handle non-personal research data in the project and facilitate data re-use.
title: The Language Learning Activity of Individual Learners Using Online Tasks
Creators: name: Montoro Sanjosé, Carlos Rubin
Publisher: name: The Open University
Year: 2013

description: This study combines an initial interest in private speech (Flavell 1966; Vygostky 1987; Ohta 2001; Ellis 2003), that is, self-addressed speech, used by individual language learners as they interact with online tasks, with a practice-based concern with the introduction of technology in a new self-access centre at the University of Guanajuato, Mexico. This had been done with little concern for the state of preparedness of learners and practitioners, as is often the case elsewhere (Benson 2001; Donaldson and Haggstrom 2006; Levy 2007; Winke and Goertler 2008). Literature on CALL, autonomy and task-based pedagogy revealed the need for an integrated, broad approach beyond technology itself with a special emphasis on the learning context, sociocultural issues and learner background. Often unexplored, the gap between what teachers plan and what learners do with tasks (Nunan 1989; Coughlan and Duff 1994; Roebuck 2000) began to focus the research efforts on investigating the nature of the language learning activity (Beetham 2007) of individual learners. Following suggestions from various authors from different traditions (e.g., Arnold and Ducate 2011; Lantolf and Poehner 2004; Chapelle 2001; Scanlon and Issroff 2005; Kaptelinin and Nardi 2006), activity theory (Vygotsky 1987; Leontiev 1978; Engeström 1987) was chosen as the most suitable theoretical framework and some of its key concepts, such as disturbances (Engeström and Sannino 2011; see also Montoro and Hampel 2011) and contradictions (Engeström 1987), were used to conduct a two-tiered analysis of empirical data gathered electronically during an online experiment followed by stimulated recall (SR) sessions. Findings include the widespread dependence of learners on private speech, memory and oral instruction and their underuse of learning tools (especially text-based ones such as dictionaries and notes), signalling links to literacy issues to be further explored and the prevalence of orality locally. Future research should explore these literacy issues and practical ways to improve the provision of language learning opportunities.

description: Extending our recent studies of two-dimensional stellar convection to 3D, we compare three-dimensional hydrodynamic simulations to identically set-up two-dimensional simulations, for a realistic pre-main sequence star. We compare statistical quantities related to convective flows including: average velocity, vorticity, local enstrophy, and penetration depth beneath a convection zone. These statistics are produced during stationary, steady-state compressible convection in the star's convection zone. Our simulations with the MUSIC code confirm the common result that two-dimensional simulations of stellar convection have a higher magnitude of velocity on average than three-dimensional simulations. Boundary conditions and the extent of the spherical shell can affect the magnitude and variability of convective velocities. The difference between 2D and 3D velocities is dependent on these background points; in our simulations this can have an effect as large as the difference resulting from the dimensionality of the simulation. Nevertheless, radial velocities near the convective boundary are comparable in our 2D and 3D simulations. The average local enstrophy of the flow is lower for two-dimensional simulations than for three-dimensional simulations, indicating a different shape and structuring of 3D stellar convection. We perform a statistical analysis of the depth of convective penetration below the convection zone, using the model proposed in our recent study (Pratt et al. 2017). Here we analyze the convective penetration in three dimensional simulations, and compare the results to identically set-up 2D simulations. In 3D the penetration depth is as large as the penetration depth calculated from 2D simulations.

Wet prairie : an environmental history of wetlands, flooding and drainage in agricultural Manitoba, 1810-1980
Creators: name: Stunden Bower, Shannon
Publisher: name: University of British Columbia
Year: 2010

description: Southern Manitoba’s wet prairie region is marked by persistent problems with surface water management. Through a historical geographical approach to wetlands, flooding, and drainage from the early 19th to the late 20th century, this dissertation offers an environmental history of a dynamic landscape, emphasizing the complex two-way relations between changes in human communities and environmental conditions. European newcomers mimicked Aboriginal populations in making use of wetland resources, and the development of property relations attuned to the local environment helped define the Red River settlement, established at the forks of the Red and Assiniboine Rivers in 1812. The creation of the Province of Manitoba in 1870 prompted new disputes over land rights, and perceived racial distinctions were consolidated by differences in how Aboriginal and non-Aboriginal claims were adjudicated. Farming expanded in late 19th century Manitoba. Many farmers failed to account for environmental variability and found their progress hampered by wet areas or periodic flooding. Early government drains were inadequate, and failed ditching efforts compounded settler frustration. The Land Drainage Act of 1895 expanded reclamation, but settler expectations remained unmet. The environmental consequences of intensive agriculture compounded the problem. Provincial inquiries in the first half of the 20th century revealed the patterns of contention that, along with the ditches themselves, defined the drained landscape. Flood problems at the international border, the continental significance of waterfowl habitat, and the catastrophic 1950 flood along the Red River were catalysts of change, and led to involvement by American interests and the Canadian federal government. Still, contention continued. Ultimately, it was new concern over surface water erosion--a problem in many ways specific to the local topography of southern Manitoba--that proved most important to the reconceptualization of the drained landscape. This dissertation examines efforts to reconcile progress, property and the Manitoba landscape, often through the exercise of government authority. It engages the notions of bioregion and nation, highlighting the importance of culture in the interconnected processes of human and environmental change. Finally, it emphasizes the importance of cultivating the capacity for adaptation to dynamic environments.

We check this method in the thermally perturbed Ising model analytically, while in the scaling Lee-Yang model numerically by comparing our results to excited state g-functions, which we obtained by the analytical continuation method. We also give a simple argument for the structure of the asymptotic overlap between the finite volume boundary state and a periodic multiparticle state, which includes the ratio of Gaudin type determinants.

Discovery of the Neutron Star Spin Frequency in EXO 0748-676

description: We report the results of a search for burst oscillations during thermonuclear X-ray bursts from the low mass X-ray binary (LMXB) EXO 0748-676. With the proportional counter array (PCA) onboard the Rossi X-ray Timing Explorer (RXTE) we detected a 45 Hz oscillation in the average power spectrum of 38 thermonuclear X-ray bursts from this source. We computed power spectra with 1 Hz frequency resolution for both the rising and decaying portions of 38 X-ray bursts from the public RXTE archive. We averaged the 1 Hz power spectra and detected a significant signal at 45 Hz in the decaying phases of the bursts. The signal is detected at a significance level of 4 x 10^-8. No similar signal was detected in the rising intervals. A fit to the oscillation peak at 0.25 Hz resolution gives a frequency of 44.7 +/- 0.06 Hz and an oscillation quality factor of Q = 80 +/- 18. The average signal amplitude is 3% (rms). The detection of 45 Hz burst oscillations from EXO 0748-676 provides compelling evidence that this is the neutron star spin frequency in this system. We use the inferred spin frequency to model the widths of absorption lines from the neutron star surface and show that the widths of the absorption lines from EXO 0748-676 recently reported by Cottam et al. are consistent with a 45 Hz spin frequency as long as the neutron star radius is in the range from about 9.5-15 km. With a known spin frequency, precise modelling of the line profiles from EXO 0748-676 holds great promise for constraining the dense matter equation of state.

Device-independent certification of multipartite entanglement using measurements performed in randomly chosen triads

description: We consider the problem of demonstrating non-Bell-local correlations by performing local measurements in randomly chosen triads, i.e., three mutually unbiased bases, on a multipartite Greenberger-Horne-Zeilinger state. Our main interest lies on investigating the feasibility of using these correlations to certify multipartite entanglement in a device-independent setting. In contrast to previous works, our numerical results up to the eight-partite scenario suggest that if each triad is randomly but uniformly chosen according to the Haar measure, one always (except possibly for a set of measure zero) finds Bell-inequality-violating correlations. In fact, a substantial fraction of these is even sufficient to reveal, in a device-independent manner, various higher-order entanglement. In particular, for the specific cases of three parties and four parties, our results---obtained from semidefinite programming---suggest that these randomly generated correlations always reveal, even in the presence of a non-negligible amount of white noise, the genuine multipartite entanglement possessed by these states. In other words, provided local calibration can be carried out to good precision, a device-independent certification of the genuine multipartite entanglement contained in these states can, in principle, also be carried out in an experimental situation without sharing a global reference frame.

description: We develop a new formulation of the functional renormalization group (RG) for interacting fermions. Our approach unifies the purely fermionic formulation based on the Grassmannian functional integral, which has been used in recent years by many authors, with the traditional Wilsonian RG approach to quantum systems pioneered by Hertz [Phys. Rev. B 14, 1165 (1976)], which attempts to describe the infrared behavior of the system in terms of an effective bosonic theory associated with the soft modes of the underlying fermionic problem. In our approach, we decouple the interaction by means of a suitable Hubbard-Stratonovich transformation (following the Hertz-approach), but do not eliminate the fermions; instead, we derive an exact hierarchy of RG flow equations for the irreducible vertices of the resulting coupled field theory involving both fermionic and bosonic fields. The freedom of choosing a momentum transfer cutoff for the bosonic soft modes in addition to the usual band cutoff for the fermions opens the possibility of new RG schemes. In particular, we show how the exact solution of the Tomonaga-Luttinger model emerges from the functional RG if one works with a momentum transfer cutoff. Then the Ward identities associated with the local particle conservation at each Fermi point are valid at every stage of the RG flow and provide a solution of an infinite hierarchy of flow equations for the irreducible vertices. The RG flow equation for the irreducible single-particle self-energy can then be closed and can be reduced to a linear integro-differential equation, the solution of which yields the result familiar from bosonization. We suggest new truncation schemes of the exact hierarchy of flow equations, which might be useful even outside the weak coupling regime.

title: Improving Information Retrieval Bug Localisation Using Contextual Heuristics
Creators: name: Dilshener, Tezcan
Publisher: name: The Open University
Year: 2017

description: Software developers working on unfamiliar systems are challenged to identify where and how high-level concepts are implemented in the source code prior to performing maintenance tasks. Bug localisation is a core program comprehension activity in software maintenance: given the observation of a bug, e.g. via a bug report, where is it located in the source code? Information retrieval (IR) approaches see the bug report as the query, and the source files as the documents to be retrieved, ranked by relevance. Current approaches rely on project history, in particular previously fixed bugs and versions of the source code. Existing IR techniques fall short of providing adequate solutions in finding all the source code files relevant for a bug. Without additional help, bug localisation can become a tedious, time- consuming and error-prone task. My research contributes a novel algorithm that, given a bug report and the application’s source files, uses a combination of lexical and structural information to suggest, in a ranked order, files that may have to be changed to resolve the reported bug without requiring past code and similar reports. I study eight applications for which I had access to the user guide, the source code, and some bug reports. I compare the relative importance and the occurrence of the domain concepts in the project artefacts and measure the effectiveness of using only concept key words to locate files relevant for a bug compared to using all the words of a bug report. Measuring my approach against six others, using their five metrics and eight projects, I position an effected file in the top-1, top-5 and top-10 ranks on average for 44%, 69% and 76% of the bug reports respectively. This is an improvement of 23%, 16% and 11% respectively over the best performing current state-of-the-art tool. Finally, I evaluate my algorithm with a range of industrial applications in user studies, and found that it is superior to simple string search, as often performed by developers. These results show the applicability of my approach to software projects without history and offers a simpler light-weight solution.

description: The purpose of this study is to examine the relationship between adoption statuses on multiple measures of child behavioral outcomes, mediated by parenting practices. Data from the first wave of National Longitudinal Survey of Children and Youth (NLSCY) was used to look at 145 adopted children (51 females and 77 males) between 4-11 years of age. Investment theory and sociobiological theory is used as the framework and suggested that adoptive parents invest less in parenting than genetically related parents, resulting in different child behavior outcomes. The data was examined to observe (1) if there is a difference in parenting practices between adoptive parents and biological parents; (2) if child outcomes are related to parenting practices; and (3) if child outcomes differ for adopted children versus biological children when parenting practices are controlled. The results that were found fail to support the hypotheses and instead lend some credibility to the view that intact adoptive parental practices and child behaviors do not differ from intact biological parental practices and child behavior. This research exposes myths regarding adoptive statuses for future adoptive parents and adopted children.

description: Recent studies concerning the point electricity price forecasting have shown evidence that the hourly German Intraday Continuous Market is weak-form efficient. Therefore, we take a novel, advanced approach to the problem. A probabilistic forecasting of the hourly intraday electricity prices is performed by simulating trajectories in every trading window to receive a realistic ensemble to allow for more efficient intraday trading and redispatch. A generalized additive model is fitted to the price differences with the assumption that they follow a zero-inflated distribution, precisely a mixture of the Dirac and the Student's t-distributions. Moreover, the mixing term is estimated using a high-dimensional logistic regression with lasso penalty. We model the expected value and volatility of the series using i.a. autoregressive and no-trade effects or load, wind and solar generation forecasts and accounting for the non-linearities in e.g. time to maturity. Both the in-sample characteristics and forecasting performance are analysed using a rolling window forecasting study. Multiple versions of the model are compared to several benchmark models and evaluated using probabilistic forecasting measures and significance tests. The study aims to forecast the price distribution in the German Intraday Continuous Market in the last 3 hours of trading, but the approach allows for application to other continuous markets, especially in Europe. The results prove superiority of the mixture model over the benchmarks gaining the most from the modelling of the volatility. They also indicate that the introduction of XBID reduced the market volatility.

description: Im Mittelpunkt dieser Arbeit steht der Entwurf des Viertels an der Meeresküste in der Stadt Pula, Kroatien. Dieser Teil der Stadt befindet sich in einer großteils verlassenen Gegend, die nahe dem historischen Zentrum liegt. Die Stadt Pula, seit jeher ein militärischer und industrieller Drehpunkt, hat eine physische und psychologische Distanz zur Meeresküste entwickelt, aus welcher sie sich eigentlich entwickelt hat. In Weiterentwicklung der Analyse, die sich an der geschichtlichen Entwicklung und der gegenwärtige Situation in Pula gehalten hat, wurde dieses Projekt so entwickelt, dass die Stadt wieder mit dem Meer verbunden wird, mit dem Hintergedanken das dahinterstehende Potential dieser Verbindung zu mobilisieren und der Stadt eine neue Ansicht zu verleihen. Der Hauptaugenmerk wurde auf die öffentlichen Plätze und deren mögliche Nutzung gelegt.
description: The purpose of this work is to design a new waterfront district for the city of Pula, Croatia, on an area that lies mostly abandoned in the close proximity of its historical center. The city of Pula, due to its role as a military and industrial center, has developed a physical and psychological distance from the waterfronts of a large bay in which the town emerged. After the analysis of the historical development and the present situation of Pula, a project is designed to fulfil the needs of the city to re-connect to the water, as to exploit the potentials and create a new image of itself. Emphasis has been placed on the open spaces and the possibilities of their use.

description: In the standard model, energy release in dense stars is severely restricted by the Pauli exclusion principle. However, if, in regions of space of high fermion degeneracy, there is a phase transition to a state of exact supersymmetry (SUSY), fermion to sfermion pair conversion followed by radiative transitions to the Bose ground state could lead to a highly collimated gamma ray burst. We calculate the cross section for electron to selectron pair conversion in a SUSY bubble and construct a monte carlo for the resulting sfermion amplification by stimulated emission.

description: The outer region (0.75--1.25 r_e in the B-band) of the merger-remnant elliptical NGC 3610 is studied using extremely high signal to noise Keck spectra, with a supplementary spectrum of the galaxy center. Stellar population parameters -- age, [Z/H], [$α$/Fe] -- are measured in several apertures along the slit. Using the multi-index simultaneous fitting method of Proctor et al. (2004), no significant stellar population gradients are detected in the outer parts of the galaxy. The overall gradients relative to the galaxy center are consistent with those found in many other early-type galaxies, though the metallicity gradient is much steeper than would be expected if NGC 3610 formed in a major merger event. Standard analysis methods using the H$β$ index are found to produce spurious radially variable gradients.

description: We study the potential impact on the electroweak (EW) fits due to the tensions between the current determinations of the hadronic vacuum polarisation (HVP) contributions to the anomalous magnetic moment of the muon ($a_μ$), based on either phenomenological dispersion integrals using measured hadronic spectra or on Lattice QCD calculations. The impact of the current tension between the experimental measurement of $a_μ$ and the total theoretical prediction based on the phenomenological calculations of the HVP are also studied. The correlations between the uncertainties of the theoretical predictions of $a_μ$ and of the running of $α_{QED}$ are taken into account in the studies. We conclude that the impact on the EW fit can be large in improbable scenarios involving global shifts of the full HVP contribution, while it is much smaller if the shift is restricted to a lower mass range and/or if the shift in $α_{QED}$ is obtained from that in $a_μ$ through appropriate use of the correlations. Indeed, the latter scenarios only imply at most a 2.6/16 increase in the $χ^2/n.d.f.$ of the EW fits and relatively small changes for the resulting fit parameter values.

description: Ultra-hot Jupiters are gas giants planets whose dayside temperature, due to the strong irradiation received from the host star, is greater than 2200 K. These kind of objects are perfect laboratories to study chemistry of exoplanetary upper atmospheres via transmission spectroscopy. Exo-atmospheric absorption features are buried in the noise of the in-transit residual spectra. However we can retrieve the information of hundreds of atmospheric absorption lines by performing a cross-correlation with an atmospheric transmission model, which allows us to greatly increase the exo-atmospheric signal. At the high-spectral resolution of our data, the Rossiter-McLaughlin effect and centre-to-limb variation have a strong contribution. Here, we present the first detection of Fe I and the confirmation of absorption features of Fe II in the atmosphere of the ultra-hot Jupiter MASCARA-2b/KELT-20b, by using three transit observations with HARPS-N. After combining all transit observations we find a high cross-correlation signal of Fe I and Fe II with signal-to-noise ratios of 10.5 +/- 0.4 and 8.6 +/- 0.5, respectively. The peak absorption for both species appear to be blue-shifted with velocities of -6.3 +/- 0.8 km/s for Fe I and -2.8 +/- 0.8 km/s for Fe II, suggesting the presence of winds from the day- to night-side of the planet's atmosphere. These results confirm previous studies of this planet and add a new atomic species (Fe I) to the long list of detected species in the atmosphere of MASCARA-2b, making it, together with KELT-9b, the most feature-rich ultra-hot Jupiter to date.

description: I describe a framework for adaptive scientific exploration based on iterating an Observation--Inference--Design cycle that allows adjustment of hypotheses and observing protocols in response to the results of observation on-the-fly, as data are gathered. The framework uses a unified Bayesian methodology for the inference and design stages: Bayesian inference to quantify what we have learned from the available data and predict future data, and Bayesian decision theory to identify which new observations would teach us the most. When the goal of the experiment is simply to make inferences, the framework identifies a computationally efficient iterative ``maximum entropy sampling'' strategy as the optimal strategy in settings where the noise statistics are independent of signal properties. Results of applying the method to two ``toy'' problems with simulated data--measuring the orbit of an extrasolar planet, and locating a hidden one-dimensional object--show the approach can significantly improve observational efficiency in settings that have well-defined nonlinear models. I conclude with a list of open issues that must be addressed to make Bayesian adaptive exploration a practical and reliable tool for optimizing scientific exploration.

Accounting for Source Uncertainties in Analyses of Astronomical Survey Data

description: I discuss an issue arising in analyzing data from astronomical surveys: accounting for measurement uncertainties in the properties of individual sources detected in a survey when making inferences about the entire population of sources. Source uncertainties require the analyst to introduce unknown ``incidental'' parameters for each source. The number of parameters thus grows with the size of the sample, and standard theorems guaranteeing asymptotic convergence of maximum likelihood estimates fail in such settings. From the Bayesian point of view, the missing ingredient in such analyses is accounting for the volume in the incidental parameter space via marginalization. I use simple simulations, motivated by modeling the distribution of trans-Neptunian objects surveyed in the outer solar system, to study the effects of source uncertainties on inferences. The simulations show that current non-Bayesian methods for handling source uncertainties (ignoring them, or using an ad hoc incidental parameter integration) produce incorrect inferences, with errors that grow more severe with increasing sample size. In contrast, accounting for source uncertainty via marginalization leads to sound inferences for any sample size.

description: Mixed $^3$He-$^4$He droplets created by hydrodynamic instability of a cryogenic fluid-jet may acquire angular momentum during their passage through the nozzle of the experimental apparatus. These free-standing droplets cool down to very low temperatures undergoing isotopic segregation, developing a nearly pure $^3$He crust surrounding a very $^4$He-rich superfluid core. Here, the stability and appearance of rotating mixed helium droplets are investigated using Density Functional Theory for an isotopic composition that highlights, with some marked exceptions related to the existence of the superfluid inner core, the analogies with viscous rotating droplets.
