Data and scripts from: Formation and evolution of turbulence in convectively unstable internal solitary waves of depression shoaling over gentle slopes in the South China Sea [Dataset]. Cornell University Library eCommons Repository. https://doi.org/10.7298/FK0S-3J13.The shoaling of high-amplitude Internal Solitary Waves (ISWs) of depression in the South China Sea (SCS) is examined through large-scale parallel turbulence-resolving high-accuracy/resolution simulations. A select, near-isobath-normal, bathymetric transect of the gentle SCS continental slope is employed together with stratification and current profiles obtained by in-situ measurements. Three simulations of separate ISWs with initial deep-water amplitudes in the range [136m, 150m] leverage a novel wave-tracking capability for a propagation distance of 80km and accurately reproduce key features of in-situ-observed phenomena with significantly higher spatiotemporal resolution. The interplay between convective and shear instability and the associated turbulence formation and evolution, as a function of deep-water ISW amplitude are further studied in-part revealing processes previously not observed in the field. Across all three waves, the convective instability develops in a similar fashion. Heavier water entrained from the wave rear plunges into its interior, giving rise to transient, yet distinct, subsurface vortical structures. Ultimately, a gravity current is triggered which horizontally advances through the wave interior and mixes it down to pycnocline’s base. Although the waveform remains distinctly symmetric, Kelvin-Helmholtz billows emerge near the well-mixed ISW trough, disturb the wave’s trailing edge and give rise to an active wake. The evolution of the kinetic energy associated with finer-scale perturbations to the ISW-induced velocity field shows two different growth regimes, each dominated by either convective or shear instability. The wake’s perturbation kinetic energy is nonlinearly dependent on deep-water wave amplitude and can become a sizable fraction of the kinetic energy of the deep-water ISW.National Science Foundation (NSF) grant OCE-1634257

Sex Work and Paying for Time: Agency, vulnerability and the ethics of participant payment
No full textThis article explores the ethical and procedural challenges associated with the payment of sex workers who engage in research. Our reflections are built upon a study exploring peer-to-peer support services for sex workers and highlight common ethical, institutional and sector-wide policies associated with researching vulnerable and marginalised groups. Through our analysis, we argue that institutional ethics ‘at a distance’ - particularly those concerning payment methods and amounts to co-researchers and participants - inadvertently re-stigmatises, paternalises and exacerbates ethical and personal risks associated with participating in the research itself. This paper draws on the relationship between vulnerability, risk and stigma to understand the function and impact of the institutional ethical processes which are common across a range of disciplines, with a particular focus on psychology and the social sciences. By uncritically positioning sex workers within broader understandings of ‘vulnerability’ and ‘risky’ or ‘at risk’ groups, we argue that institutional processes of additional risk management inadvertently reproduce the marginalisation and personal risks they seek to avert. This leads us to question the relationship between institutional ‘ethical’ procedures across the university sector and the ethics of the personal outcomes they produce. We advocate for the adoption of responsive and co-produced ethical policies and guidance on payment methods and amounts. Such positioning should be reflective of those seen in medical research and premised on a feminist ethic of care, promoting a more liberalised, flexible and inclusive approach to participant payment
Plastic Effects: The “Ongoing Process” of Hair Removal and the Multiple Temporalities of Plastic Pots
No full textExamining how the polypropylene pots in which depilatory wax is packaged are active in the production of ‘feminine’ hairlessness in London's beauty salons and what happens as they are disposed of and incinerated, this article focuses on the making of bodies to explore plastic's temporalities. Centering the materiality of the plastic packaging (strong, light, flexible, replaceable, disposable), the article explores what the pots are and so what the pots do: what they effect, including how plastic comes to configure bodies in different and potentially harmful ways. Considering how plastic endures in bodies brings to the fore its multiple temporalities, heterochronic, layered and folded into one another

‘A near perfect microcosm of England’: The 1975 Woolwich West By-Election
No full textThe 1975 Woolwich West by-election was highly significant for Labour, the Conservatives, and the Liberals as the constituency of Woolwich West represented a microcosm of the country at large and had proven a strikingly accurate barometer of national opinion since the end of the Second World War. As this article demonstrates, the election provides important insight into how far party alignment had weakened among voters by 1975 and how issue voting rather than party allegiance increasingly dominated voter behaviour. This piece furthermore highlights the importance of the election in constituting a break with several traditions and conventions of election campaigning as well as the introduction of new tactics and strategies that would come to define political structures. As this article shows, voter dealignment, issue voting, large numbers of at times highly unusual candidates, the refusal of candidates to debate each other, and novel ways of attracting voter attention all defined both the Woolwich West by-election and British political culture of the decades to come
Experimental Research Using Physical Models for Architecture: Creation and Optimisation of Air-Actuated Kinetic Cushion Structures
No full textThis paper presents a review about the design and use of scale model testing by relevant pioneers, and experimental research using physical models to create and optimise air-actuated kinetic cushion structures for architecture and engineering. Air-actuated kinetic cushion constructions could improve assembly, erection, and transportation of structures. Analysis, testing and evaluation of physical models are useful for developing complex structures as it does not require to use simplified hypothesis to reduce mathematical difficulties, and the process of making models sometimes provides insights that were unforeseen. The Structural Combination Matrix (SCM) is created and used as an open-ended framework for creating innovative sustainable architecture. Six elements of the SCM have been modelled and analysed
