Intersectional Discrimination Is Associated with Housing Instability among Trans Women Living in the San Francisco Bay Area.
Trans women face numerous structural barriers to health due to discrimination. Housing instability is an important structural determinant of poor health outcomes among trans women. The purpose of this study was to determine if experiences of intersectional anti-trans and racial discrimination are associated with poor housing outcomes among trans women in the San Francisco Bay Area. A secondary analysis of baseline data from the Trans *National study (n = 629) at the San Francisco Department of Public Health (2016-2018) was conducted. Multivariable logistic regression was used to analyze the association between discrimination as an ordered categorical variable (zero, one to two, or three or more experiences) and housing status adjusting for age, years lived in the Bay Area, and gender identity. We found that the odds of housing instability increased by 1.25 for every categorical unit increase (1-2, or 3+) in reported experiences of intersectional (both anti-trans and racial) discrimination for trans women (95% CI = 1.01-1.54, p-value < 0.05). Intersectional anti-trans and racial discrimination is associated with increased housing instability among trans women, giving some insight that policies and programs are needed to identify and address racism and anti-trans stigma towards trans women. Efforts to address intersectional discrimination may positively impact housing stability, with potential for ancillary effects on increasing the health and wellness of trans women who face multiple disparities
Yokel with a yoke: carrying the country through the city in activist walking performance
What happens when an eco-activist artist from the country sets foot in the city? Drop in the Ocean is a six-day solo walking performance in six concentric circles, performed around an accompanying installation. The performer carries water in two buckets on a milkmaid’s yoke as a visual provocation to effect encounters with strangers. She invites them to make a wish by placing their hand in the water of one bucket, taking a stone and transferring it to the other. In between, she asks them to hold the stone in their wet hand while she recites a sonorous score – poetic instructions for how they might think about water in all its guises from the domestic to the sublime. As a play on temporal and spatial incongruity – the anachronistic yoke; the car park, bus stop, field or park bench as the unlikely location of live art – it is an attempt to disrupt presumption and challenge perception. In asking participants to submit to submersion, it is a subliminal conceit to facilitate a space of appreciation for an element which we over-abstract. And in using water to bring the (fabled) sensuality of the wild into the (perceived) sterility of the city, it was an alchemical experiment in enchanted activism (in a bucket).Drop was first performed in and around Hereford, October 2013. Beginning and ending each day in the installation housed at All Saints Church – in the circular labyrinth constructed as its centre – the walks rippled outwards, increasing in diameter, duration and difficulty as the week progressed. In doing so they became virtual contour lines: striding indiscriminately across boundaries, trespassing over thresholds of perception, dissolving the rural-urban binary into a continuum of meetings with people, cows, terrain, traffic. It revealed in its wake that the politics of the piece might not be in the water but in the wandering: like bringing the smell of cow shit on my boots back to a city that lost its cattle market to a shopping centre. Here I offer these and other reflections of a (mostly rural) activist meeting her (mostly urban) audience through the medium of water.dropintheocean.org.u
All in a Day's Walk - From Slowing Down to Walking Fast
‘I have always been a fast walker. I have not always been a walk-faster.’All in a Day’s Walk was devised as a month-long performance in which I would live entirely within the distance I could walk away from home and back in a day, eating only the food that was grown, processed and obtainable within that distance. As a first foray into tracktivism – my own neologism for a synthesis of two distinct (and inherently slow) practices: the aesthetic arsenal of an artistic (rural) walking practice stealthily redeployed to facilitate (activist) conversational encounters with strangers in the dialogical arts tradition – it was designed as a frame to draw attention to the loss of rural infrastructure. As a dairy-allergic vegetarian in the floods and frosts of a Herefordshire December, it became a loss that drew attention to my frame: an unexpectedly bleak, long-drawn out fast that slowed me to a stand-still. A slow epiphany emerged: what happens to an activist pedestrian practice in the space of deceleration between slowness and stillness? With reference to somatics, slow food, walking and running, I consider the efficacy of going beyond slow in an activist-pedestrian-dialogical performance practice: if ‘speed institutes a process of collective forgetting’ (Lavery 2005: 150), how can slowing or stopping reverse this trend towards a collective (and embodied) remembering, and render an environmentalist performance practice more powerful for being infused with a more-than homeopathic dilution of the urgency of ecological crisis? www.allinadayswalk.co.u
Energy gap in superconducting fullerides: optical and tunneling studies
Tunneling and optical transmission studies have been performed on
superconducting samples of Rb3C60. At temperatures much below the
superconducting transition temperature Tc the energy gap is 2 Delta=5.2 +-
0.2meV, corresponding to 2 Delta/kB Tc = 4.2. The low temperature density of
states, and the temperature dependence of the optical conductivity resembles
the BCS behavior, although there is an enhanced ``normal state" contribution.
The results indicate that this fulleride material is an s-wave superconductor,
but the superconductivity cannot be described in the weak coupling limit.Comment: RevTex file with four .EPS figures. Prints to four pages. Also

Supporting parent-child conversations in a history museum
BACKGROUND: Museums can serve as rich resources for families to learn about the social world through engagement with exhibits and parent-child conversation about exhibits.
AIMS: This study examined ways of engaging parents and child about two related exhibits at a cultural and history museum. Sample participants consisted of families visiting the Animal Antics and the Gone Potty exhibits at the British Museum.
METHODS: Whilst visiting two exhibits at the British Museum, 30 families were assigned to use a backpack of activities, 13 were assigned to a booklet of activities, and 15 were assigned to visit the exhibits without props (control condition).
RESULTS: Compared to the families in the control condition, the interventions increased the amount of time parents and children engaged together with the exhibit. Additionally, recordings of the conversations revealed that adults asked more questions related to the exhibits when assigned to the two intervention conditions compared to the control group. Children engaged in more historical talk when using the booklets than in the other two conditions.
CONCLUSIONS: The findings suggest that providing support with either booklets or activities for children at exhibits may prove beneficial to parent-child conversations and engagement with museum exhibits
Superconductivity in Fullerides
Experimental studies of superconductivity properties of fullerides are
briefly reviewed. Theoretical calculations of the electron-phonon coupling, in
particular for the intramolecular phonons, are discussed extensively. The
calculations are compared with coupling constants deduced from a number of
different experimental techniques. It is discussed why the A_3 C_60 are not
Mott-Hubbard insulators, in spite of the large Coulomb interaction. Estimates
of the Coulomb pseudopotential , describing the effect of the Coulomb
repulsion on the superconductivity, as well as possible electronic mechanisms
for the superconductivity are reviewed. The calculation of various properties
within the Migdal-Eliashberg theory and attempts to go beyond this theory are
described.Comment: 33 pages, latex2e, revtex using rmp style, 15 figures, submitted to
