Background and Aims: Machine learning algorithms can detect at-risk online gamblers by analyzing patterns in betting behaviour. Example models have been tested in several jurisdictions, but their performance over time has not been assessed. We investigated the temporal stability of two existing models after 30-months (2019 – 2022). We further aimed to identify potential sources of model degradation, and strategies to restore prior classification performance.Design: Revalidation of a large-scale study linking participants’ self-reported gambling problems to their online gambling behaviours.Setting: Online gambling website operated by a Canadian provincial gambling operator.Participants: Adults aged 18+ (N = 11,258) who completed a survey and participated in online gambling. Measurements: Two binary dependent variables based on validated risk thresholds for the Problem Gambling Severity Index (PGSI) identified participants who reported a high- (PGSI 8+) or moderate-to-high (PGSI 5+) risk of past-year gambling problems. Previously-developed machine learning models made predictions about these dependent variables based on 10 inputs derived from participants’ deposits, betting behaviour and account-level data on the site.Findings: Significant changes between the prior validation study and current revalidation analysis were evident in threshold-dependent metrics (sensitivity and specificity), as well as the models’ Area Under the Precision-Recall Curve (AUPRC; PGSI 5+ ΔAUPRC = +2.87%; t(20401) = 2.83, p = .004, 95% CI [60.59, 61.57]; PGSI 8+ ΔAUPRC = +7.06%; t(20401) = 7.21, p < .001, 95% CI [44.47, 45.62]). These changes may be attributable to observed drifts in the distributions of the input and dependent variables. Redeveloping the models’ decision thresholds restored previously-observed levels of classification performance for threshold-dependent metrics only.Conclusion: Machine learning models predicting PGSI risk categories via indicators of online gambling behaviour may continue to function adequately 30 months after validation. These results provide preliminary support for their utility in real-world detection tasks, and speak to the temporal stability of the behavioural profile of problematic gambling.

Extreme conditions inside ice giants such as Uranus and Neptune can result in peculiar chemistry and structural transitions, e.g., the precipitation of diamonds or superionic water, as so far experimentally observed only for pure C─H and H 2 O systems, respectively. Here, we investigate a stoichiometric mixture of C and H 2 O by shock-compressing polyethylene terephthalate (PET) plastics and performing in situ x-ray probing. We observe diamond formation at pressures between 72 ± 7 and 125 ± 13 GPa at temperatures ranging from ~3500 to ~6000 K. Combining x-ray diffraction and small-angle x-ray scattering, we access the kinetics of this exotic reaction. The observed demixing of C and H 2 O suggests that diamond precipitation inside the ice giants is enhanced by oxygen, which can lead to isolated water and thus the formation of superionic structures relevant to the planets’ magnetic fields. Moreover, our measurements indicate a way of producing nanodiamonds by simple laser-driven shock compression of cheap PET plastics.

This article examines Canada’s first internet gambling website blocking scheme, which was enacted in Quebec as part of the implementation of the province’s 2015 budget. Using qualitative research methods, the article illustrates the complexities of regulating online gambling. Influenced by critical sociological and anthropological studies of gambling, and taking a socio-legal, governmentality perspective, it shows how socio-legal studies can illuminate research on the regulation of gambling, and how the study of online gambling can, as a sentinel site for the regulation of online consumption, contribute to the development of socio-legal studies. Our analysis shows that the governmentality of online gambling is framed so as to exclude 1) a range of risks (e.g., related to consumer profiling and the capacity to stimulate “addictive consumption”), 2) the heterogeneity of everyday experience that connects online gambling with online addictive consumption more generally, and 3) a range of possibilities for governing online gambling otherwise.

The rise of platforms as the premier model of videogame distribution has led to a number of changes in the business models of producers and distributors. Consumers are constantly hailed by games platforms through freemium business models that offer cosmetic items contained in loot boxes or recurring subscriptions. Thus far, game studies and consumer studies have been unable to account for the totality of how these new and dynamic platforms circumvent legal barriers and attract potential consumers. This paper argues that a hybrid research model combining platform studies, socio-cultural critique of gamblification, and political economy is required in order to theorize and explicate how these platforms operate. The platformized and gamblified model for game distribution seeks to regulate and configure networks of association between consumers and producers with the ultimate aim of eliciting participation on platforms.

Regulatory approaches to games are organized by boundaries between game/not-game, game/gambling game, skilled/unskilled play, consumption/production. Perhaps more importantly, moral justifications for regulating gambling (and condemning digital games) are rooted in the idea that they consume our time and wages but give little in return. This article uses two case studies to show how these boundaries and justifications are now perforated and reconfigured by digital mediation. The case study of Daily Fantasy Sports (DFS) illustrates a contemporary challenge to rigid dichotomies between game/not game, skilled/unskilled play, and game/gambling game, demonstrating how regulation becomes deterritorialized as gambling moves out of state-regulated physical casinos and takes the form of networked, digital games. Our second case study of Pokémon Go approaches regulation from a different direction, complicating the rigid dichotomy between production/consumption in online networked play. We show how play is increasingly realized as productive in economic, social, physical, subjective and analytic registers, while at the same time, it is driven by gambling design imperatives, such as extending time-on-device. Pokémon Go exemplifies analytic productivity, a term we use to refer to the production of data flows that can be leveraged for a wide variety of purposes, including to predict, shape, and channel the behaviour of player populations, thereby generating multiple streams of revenue. Ultimately, both cases illustrate how digital games and gambling increasingly blur into each other, complicating the regulatory landscape.

The miscibility gap in hydrogen-water mixtures is investigated by conducting Gibbs-ensemble Monte Carlo simulations with analytical two-body interaction potentials between the molecular species. We calculate several demixing curves at pressures below 150 kbar and temperatures of 1000 K ≤ T ≤ 2000 K. Despite the approximations introduced by the two-body interaction potentials, our results predict a large miscibility gap in hydrogen-water mixtures at similar conditions as found in experiments. Our findings are in contrast to those from ab initio simulations and provide a renewed indication that hydrogen-water immiscibility regions may have a significant impact on the structure and evolution of ice giant planets like Uranus and Neptune.

We investigate the thermopower and Lorenz number of hydrogen with Kohn-Sham density functional theory (DFT) across the plasma plane toward the near-classical limit, i.e., weakly degenerate and weakly coupled states. Our results are in concordance with certain limiting values for the Lorentz plasma, a model system which only considers electron-ion scattering. Thereby, we clearly show that the widely used method of calculating transport properties via the Kubo-Greenwood (KG) formalism does not capture electron-electron scattering processes. Our discussion also addresses the inadequateness of assuming a Drude-like frequency behavior for the conductivity of nondegenerate plasmas by revisiting the relaxation time approximation within kinetic theory.

The transformation of games with the advent of platformized distribution systems continues to produce new and agile forms of consumption and exploitation. Valve Corporation’s DOTA 2 is a key example of a gaming space that is constantly atomized and rebuilt with the aim of optimizing player participation. This participatory form is ever-more gamblified and framed by systems designed to habituate players to a new form of consumption. This article explores how DOTA 2 transforms every year with the advent of a yearly Battle Pass, brimming with gambling systems aimed at eliciting specific forms of user participation. We catalog and schematize these systems with the aim of shedding light on the inner workings of DOTA 2 during this season. The purpose of our work is to move the discussion beyond a regulatory focus on symptomatic loot boxes and toward a deeper understanding of the rhetorical systems hiding beneath game systems.

In recent years, there has been an explosion of “experiential design” in casinos, driven in part by research suggesting that curating gambling sensescapes can lure patrons to spend more time – and ...

Gambling markets have drastically expanded over the past 35 years. Pacing this expansion has been the articulation of a governance framework that largely places responsibility for regulating gambling-related harms upon individuals. This framework, often defined with reference to the concept of responsible gambling (RG), has faced significant criticism, emphasizing public health and consumer protection issues. To study both the articulation and critique of the concept of responsible gambling, we conducted a ‘scoping review’ of the literature (Arksey & O’Malley 2005). Literature was identified through searches on academic databases using a combination of search terms. Articles were independently reviewed by two researchers. Findings indicate 142 publications with a primary focus on responsible gambling, with a high volume of publications coming from the disciplinary backgrounds of the first authors representing the fields of psychology, business, and psychiatric medicine. Further, publication key themes address topics such as responsible gambling tools and interventions, corporate social responsibility and accountability, responsible gambling concepts and descriptions, and to a lesser extent, critiques of responsible gambling. The scoping review of the literature related to responsible gambling suggests the need to foster research conditions to invite more critical and interdisciplinary scholarship in an effort to improve public health and consumer protection.

We are currently in the midst of a global pandemic with the spread of Coronavirus Disease 2019 (COVID-19). While we do not know how this situation will unfold or resolve, we do have insight into how it fits within existing patterns and relations, particularly those pertaining to sociocultural constructions of (in)security, vulnerability, and risk. We can see evidence of surveillance dynamics at play with how bodies and pathogens are being measured, tracked, predicted, and regulated. We can grasp how threat is being racialized, how and why institutions are flailing, and how social media might be fueling social divisions. There is, in other words, a lot that our scholarly community could add to the conversation. In this rapid-response editorial, we provide an introduction to the framing devices of disease surveillance and discuss how a surveillance studies orientation could help us think critically about the present crisis and its possible aftermath.

The small semimajor axes of hot Jupiters lead to high atmospheric temperatures of up to several thousand Kelvin. Under these conditions, thermally ionized metals provide a rich source of charged particles and thus build up a sizeable electrical conductivity. Subsequent electromagnetic effects, such as the induction of electric currents, Ohmic heating, magnetic drag, or the weakening of zonal winds have thus far been considered mainly in the framework of a linear, steady-state model of induction. For hot Jupiters with an equilibrium temperature Teq > 1500 K, the induction of atmospheric magnetic fields is a runaway process that can only be stopped by non-linear feedback. For example, the back-reaction of the magnetic field on to the flow via the Lorentz force or the occurrence of magnetic instabilities. Moreover, we discuss the possibility of self-excited atmospheric dynamos. Our results suggest that the induced atmospheric magnetic fields and electric currents become independent of the electrical conductivity and the internal field, but instead are limited by the planetary rotation rate and wind speed. As an explicit example, we characterize the induction process for the hottest exoplanet, KELT-9b, by calculating the electrical conductivity along atmospheric P–T profiles for the dayside and nightside. Despite the temperature varying between 3000 and 4500 K, the resulting electrical conductivity attains an elevated value of roughly 1 S m−1 throughout the atmosphere. The induced magnetic fields are predominately horizontal and might reach up to a saturation field strength of 400 mT, exceeding the internal field by two orders of magnitude.

Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficiently understood and models rely imperatively on data for equation of state and transport properties [1,2]. Despite its great significance, the experimentally accessed region of the ammonia phase diagram today is still very limited in pressure and temperature [3, 4].We investigate the equation of state, the optical properties and the electrical conductivity of warm dense ammonia by combining laser-driven shock experiments and state-of-the-art density functional theory molecular dynamics (DFT-MD) simulations [5]. The equation of state is probed along the Hugoniot of liquid NH3 up to 350 GPa and 40000 K and in very good agreement with earlier DFT-MD results [6]. Our temperature measurements show a subtle slope change at 7000 K and 90 GPa, which coincides with the gradual transition from a liquid dominated by molecules to a plasma state in our new ab initio simulations. The reflectivity data furnish the first experimental evidence of electronic conduction in high pressure ammonia and are in excellent agreement with the reflectivity computed from atomistic simulations. Corresponding electrical conductivity values are found up to one order of magnitude higher than in water in the 100 GPa regime, with possible implications on the generation of magnetic dynamos in large icy planets’ interiors.

We study ionization and transport processes in partially ionized multicomponent plasmas. The plasma composition is calculated via a system of coupled mass-action laws. The electronic transport properties are determined by the electron-ion and electron-neutral transport cross sections. The influence of electron-electron scattering is considered via a correction factor to the electron-ion contribution. Based on these data, the electrical and thermal conductivities as well as the Lorenz number are calculated. For the thermal conductivity, we consider also the contributions of the translational motion of neutral particles and of the dissociation, ionization, and recombination reactions. We apply our approach to a partially ionized plasma composed of hydrogen, helium, and a small fraction of metals (Li, Na, Ca, Fe, K, Rb, and Cs) as typical for atmospheres of hot Jupiters. We present results for the plasma composition and the transport properties as a function of density and temperature and then along typical $P\text{\ensuremath{-}}T$ profiles for the outer part of the hot Jupiter HD 209458b. The electrical conductivity profile allows revising the Ohmic heating power related to the fierce winds in the planet's atmosphere. We show that the higher temperatures suggested by recent interior models could boost the conductivity and thus the Ohmic heating power to values large enough to explain the observed inflation of HD 209458b.

We explore the performance of the Gibbs-ensemble Monte Carlo simulation technique by calculating the miscibility gap of ${\mathrm{H}}_{2}\text{\ensuremath{-}}\mathrm{He}$ mixtures with analytical exponential-six potentials. We calculate several demixing curves for pressures up to 500 kbar and for temperatures up to $1800\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ and predict a ${\mathrm{H}}_{2}\text{\ensuremath{-}}\mathrm{He}$ miscibility diagram for the solar He abundance for temperatures up to $1500\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ and determine the demixing region. Our results are in good agreement with ab initio simulations in the nondissociated region of the phase diagram. However, the particle number necessary to converge the Gibbs-ensemble Monte Carlo method is yet too large to offer a feasible combination with ab initio electronic structure calculation techniques, which would be necessary at conditions where dissociation or ionization occurs.

Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficiently understood and models rely imperatively on data for equation of state and transport properties. Despite its great significance, the experimentally accessed region of the ammonia phase diagram today is still very limited in pressure and temperature. Here we push the probed regime to unprecedented conditions, up to $\sim$350 GPa and $\sim$40000 K. Along the Hugoniot, the temperature measured as a function of pressure shows a subtle change in slope at $\sim$7000 K and $\sim$90 GPa, in agreement with ab initio simulations we have performed. This feature coincides with the gradual transition from a molecular liquid to a plasma state. Additionally, we performed reflectivity measurements, providing the first experimental evidence of electronic conduction in high-pressure ammonia. Shock reflectance continuously rises with pressure above 50 GPa and reaches saturation values above 120 GPa. Corresponding electrical conductivity values are up to 1 order of magnitude higher than in water in the 100 GPa regime, with possible significant contributions of the predicted ammonia-rich layers to the generation of magnetic dynamos in ice giant interiors., Please visit publisher's website for supplementary information

This paper examines the criminalization of HIV non-disclosure in Canada as a public health legal response. The analysis begins outside the public health framework to relate the criminalization of HIV to broader shifts in the relationship between life and law in contemporary forms of governance. It does this by drawing on the concepts of biopower and biopolitics to explain how the intersection of medical and legal knowledge creates an accusatorial framework that has made HIV criminalization possible. This idea is explored by tracing the historical development of the legal principle out of which the phenomenon has emerged (“fraud capable of vitiating consent to sexual relations”) and looking at how it has been applied in two contemporary HIV prosecution cases: R v. Aziga (2007) and R v. Ngeruka (2015). The second half of the paper examines the effectiveness of the criminal accusation of HIV non-disclosure as a public health legal response, focusing on its effect on advancing traditional public health goals. The discussion also points out how criminalization of HIV non-disclosure manifests broader tensions that have been recognized in public health legal responses to communicable disease, particularly the challenges of protecting the public while respecting individual rights. The paper concludes by arguing that control over blood blurs medical and legal forms of knowledge and power. This reflects a “seropolitical” landscape characterized by a criminal law accusatorial framework shaped by medical determinations of risk and harm.

Background Emphasis on HIV testing as a gateway to prevention, treatment and care has grown tremendously over the past decade. In turn, this emphasis on testing has created a demand for new policies, programs, and technologies that can potentially increase access to and uptake of HIV testing. HIV self-testing (HST) technologies have gained important momentum following the approval of the over-the-counter self-tests in the United States, the UK, and France. While the renewed interest in HST has given rise to a number of high quality reviews of empirical studies conducted on this topic, we have yet to find an article that captures the extent of the debate on HST. Mapping the debate A critical review of the literature on HST was conducted and organized into three categories based on the focus of the article: 1) Empirical research, 2) Arguments, and 3) Context. We focused exclusively on the second category which included ethical analyses, policy analyses, editorials, opinion pieces, commentaries, letters to the editor and so forth. 10 lines of argument on HST were identified in the literature: 1) Individual – Public Health, 2) Strengths – Limits, 3) Benefits – Harms, 4) Screening – Testing, 5) Target – Market, 6) Health Care – Industry, 7) Regulation – Restriction, 8) Resource-Rich Settings – Resource-Limited Settings, 9) Ethical – Unethical, and 10) Exceptionalism – Normalization. Each line of argument is presented and discussed in the paper. Conclusion We conclude by providing examples of critical questions that should be raised in order to take the debate to another level and generate new ways of thinking about HST.

The electrical conductivity of water under extreme temperatures and densities plays a central role in modeling planetary magnetic fields. Experimental data are vital to test theories of high-energy-density water and assess the possible development and presence of extraterrestrial life. These states are also important in biology and chemistry studies when specimens in water are confined and excited using ultrafast optical or free-electron lasers (FELs). Here we utilize femtosecond optical lasers to measure the transient reflection and transmission of ultrathin water sheet samples uniformly heated by a 13.6 nm FEL approaching a highly conducting state at electron temperatures exceeding 20 000 K. The experiment probes the trajectory of water through the high-energy-density phase space and provides insights into changes in the index of refraction, charge carrier densities, and AC electrical conductivity at optical frequencies. At excitation energy densities exceeding 10 MJ/kg, the index of refraction falls to n = 0.7, and the thermally excited free-carrier density reaches n$_e$ = 5 × 10$^{27}$ m$^{−3}$, which is over an order of magnitude higher than that of the electron carriers produced by direct photoionization. Significant specular reflection is observed owing to critical electron density shielding of electromagnetic waves. The measured optical conductivity reaches 2 × 10$^4$ S/m, a value that is one to two orders of magnitude lower than those of simple metals in a liquid state. At electron temperatures below 15 000 K, the experimental results agree well with the theoretical calculations using density-functional theory/molecular-dynamics simulations. With increasing temperature, the electron density increases and the system approaches a Fermi distribution. In this regime, the conductivities agree better with predictions from the Ziman theory of liquid metals.

Dharma-wardana et al. [M. W. C. Dharma-wardana et al., Phys. Rev. E 96, 053206 (2017)2470-004510.1103/PhysRevE.96.053206] recently calculated dynamic electrical conductivities for warm dense matter as well as for nonequilibrium two-temperature states termed "ultrafast matter" (UFM) [M. W. C. Dharma-wardana, Phys. Rev. E 93, 063205 (2016)2470-004510.1103/PhysRevE.93.063205]. In this Comment we present two evident reasons why these UFM calculations are neither suited to calculate dynamic conductivities nor x-ray Thomson scattering spectra in isochorically heated warm dense aluminum. First, the ion-ion structure factor, a major input into the conductivity and scattering spectra calculations, deviates strongly from that of isochorically heated aluminum. Second, the dynamic conductivity does not show a non-Drude behavior which is an essential prerequisite for a correct description of the absorption behavior in aluminum. Additionally, we clarify misinterpretations by Dharma-wardana et al. concerning the conductivity measurements of Gathers [G. R. Gathers, Int. J. Thermophys. 4, 209 (1983)IJTHDY0195-928X10.1007/BF00502353].

Water, methane, and ammonia are commonly considered to be the key components of the interiors of Uranus and Neptune. Modelling the planets’ internal structure, evolution, and dynamo heavily relies on the properties of the complex mixtures with uncertain exact composition in their deep interiors. Therefore, characterising icy mixtures with varying composition at planetary conditions of several hundred gigapascal and a few thousand Kelvin is crucial to improve our understanding of the ice giants. In this work, pure water, a water-ethanol mixture, and a water-ethanol-ammonia “synthetic planetary mixture” (SPM) have been compressed through laser-driven decaying shocks along their principal Hugoniot curves up to 270, 280, and 260 GPa, respectively. Measured temperatures spanned from 4000 to 25000 K, just above the coldest predicted adiabatic Uranus and Neptune profiles (3000–4000 K) but more similar to those predicted by more recent models including a thermal boundary layer (7000–14000 K). The experiments were performed at the GEKKO XII and LULI2000 laser facilities using standard optical diagnostics (Doppler velocimetry and optical pyrometry) to measure the thermodynamic state and the shock-front reflectivity at two different wavelengths. The results show that water and the mixtures undergo a similar compression path under single shock loading in agreement with Density Functional Theory Molecular Dynamics (DFT-MD) calculations using the Linear Mixing Approximation (LMA). On the contrary, their shock-front reflectivities behave differently by what concerns both the onset pressures and the saturation values, with possible impact on planetary dynamos.

The electrical $\ensuremath{\sigma}$ and thermal conductivity $\ensuremath{\lambda}$ of liquid iron are calculated with spin-polarized density-functional-theory-based simulations over a significant pressure and temperature range using the Kubo-Greenwood formalism. We show that a paramagnetic state is stable in the liquid up to high temperatures at ambient pressure and that the discrepancy between experimental results and spin-degenerate simulations for $\ensuremath{\sigma}$ and $\ensuremath{\lambda}$ of more than 30% are reduced to within 10% with lower values resulting from the spin-polarized simulations. Along the 3700 K isotherm, we explore the persistence of magnetic fluctuations toward high densities, and beyond 20--50 GPa the liquid becomes diamagnetic, which suggests the existence of a continuous paramagnetic-to-diamagnetic transition. This transition exerts a significant influence on the physical properties of liquid iron, especially on $\ensuremath{\sigma}$ and $\ensuremath{\lambda}$, and is potentially of high relevance for dynamo processes in Mercury and Mars.

Contemporary research hospitals occupy a vexed position in the policy landscape. On the one hand, as healthcare providers, they must abide by the logic of healthcare policy, which expects health research to support improved health outcomes and high quality healthcare systems. On the other hand, as research facilities, they are beholden to the logic of innovation policy, which seeks to advance research-driven, science and technology-derived innovations, where industry is the key customer and client. At the intersection of these policy logics, the research hospital must orchestrate a range of interests that may not always coexist harmoniously. Through a detailed case study of a Canadian research hospital, we illustrate organizational efforts to hybridize healthcare and innovation logics. The need to be more ‘business like’ and the expected financial and reputational rewards encourage acceptance of a mandate for technology transfer and commercialization. As well, there is hope that the entrepreneurial turn can serve the hospital's own mission, by prioritizing the needs of patients and the organization itself as a user of its own innovations. Further, insofar as successful technology transfer and commercialization is a transformative force, it is expected to enable the research hospital to achieve its goal of translational and impactful health research. As we illustrate, there is much optimism that these hybridizing efforts will produce a successful cross. Yet the trajectory of change in the context of mixed logics is necessarily uncertain, and other hybrid futures cannot be foreclosed. More sterile or monstrous outcomes remain possible, with potentially significant implications for the intellectual, economic and health benefits that will arise as a result.

This article provides an introduction to a special issue of Body & Society that explores the surveillance--embodiment nexus. It accentuates both the prevalence and consequence of bodies being increasingly converted into ‘objects of information’ by surveillance technologies and systems. We begin by regarding the normalcy of body monitoring in contemporary life, illustrating how a plurality of biometric scanners operate to intermediate the physical surfaces and subjective depths of bodies in accordance with various concerns. We focus on everyday experiences of bodily intermediation by surveillant dispositifs, and consider the broader political, epistemological, and ontological significance of these processes. We then point to the substantive intersections and divergences existing between body and surveillance studies. We conclude with an overview of the five articles appearing in this special issue. We describe how each contribution creates a template for imagining what a body is, and what a body might become, in a culture defined by proliferating data sharing behaviours, systems of codification, and practices of intermediation.

With NASA’s Juno mission having arrived at its target and ESA’s JUICE mission in planning, the interest in state-of-the-art models for the interior structure and dynamics of Jupiter is increasing. This chapter reports on the related attempts within the Special Priority Program PlanetMag of the German Science Foundation and provides an up-to-date review of the topic. Refined interior models are discussed that are based on new ab initio calculations for the equations of state for hydrogen and helium. For the first time, the depth-dependent transport properties have also been calculated, most notably an electrical conductivity profile that captures the transition from the molecular outer to the metallic inner hydrogen-rich envelopes. Anelastic simulations of convection show that the strong density stratification causes flow amplitudes to increase with radius while the flow scale decreases. Zonal jet systems very similar to those observed on Jupiter or Saturn are found in simulations of the molecular hydrogen envelope. Dynamo simulations that include the whole gaseous envelope show strikingly Jupiter-like magnetic field configurations when the strong density stratification is combined with an electrical conductivity profile that includes the significant drop in the molecular layer. While the dipole-dominated large-scale field is produced at depth, the equatorial jet can give rise to a secondary dynamo process where it reaches down to regions of sizable electrical conductivity. The magnetic surface signatures of this secondary dynamo are banded but also have more localized wave number m = 1 and m = 2 concentrations at lower latitudes. By detecting these features, the Juno mission should be able to constrain the deep dynamics of the equatorial jet.

HIV criminalisation is a term that describes the criminal prosecution of persons in instances of HIV transmission, exposure and so-called non-disclosure of their HIV serostatus. In the United States (US), there have been over 500 reported instances of HIV criminalisation. Over the past decade, several negative consequences of HIV criminalisation have been identified, including its capacity to increase stigma and social injustice. In addition, scholars have built an evidence base demonstrating that HIV criminalisation has the potential to undermine HIV prevention and that it is thus harmful to public health. This article contributes to that evidence base by (1) combining Foucaultian studies of ‘governmentality’ with the sociology of ‘anomie’ to theorise the larger implications of HIV criminalisation for the institution of public health, and (2) presenting interviews with public health service providers working in Tennessee, USA. This state is an important site for studying the public health implications of...

The validity of the widely used linear mixing approximation for the equations of state (EOS) of planetary ices is investigated at pressure-temperature conditions typical for the interior of Uranus and Neptune. The basis of this study are ab initio data ranging up to 1000 GPa and 20 000 K calculated via density functional theory molecular dynamics simulations. In particular, we calculate a new EOS for methane and EOS data for the 1:1 binary mixtures of methane, ammonia, and water, as well as their 2:1:4 ternary mixture. Additionally, the self-diffusion coefficients in the ternary mixture are calculated along three different Uranus interior profiles and compared to the values of the pure compounds. We find that deviations of the linear mixing approximation from the results of the real mixture are generally small; for the thermal EOS they amount to 4% or less. The diffusion coefficients in the mixture agree with those of the pure compounds within 20% or better. Finally, a new adiabatic model of Uranus with an inner layer of almost pure ices is developed. The model is consistent with the gravity field data and results in a rather cold interior ($\mathrm{T_{core}} \mathtt{\sim}$ 4000 K).
