We're just gonna call it all BPD

'We’re just gonna call it all BPD' three channel video, duration 1h-10min. To enable subtitles, please click on the CC icon in the video status bar. An immersive video installation, created from verbatim scripts, authored by people with lived experience of a diagnosis of Borderline Personality Disorder (BPD). “BPD” is one of the most stigmatised of all mental health diagnoses – both in the public imagination and within the health sector itself. As such, it has been criticised as a “highly contentious and damaging label” (1). Movements campaigning for its abolition point to the high correlation between childhood abuse or neglect and “BPD”, arguing that by labelling someone with a “personality disorder” we focus on what is wrong with the person—the flaws in their personality–rather than on what happened to them. The alternative would be to approach the internal experience of “BPD” as an understandable response to trauma. The characters in this piece share their experiences of this label, describing histories of trauma and illuminating the impact of relationships with caregivers, friends, family and service-providers. Their stories ‘from the inside’, help us to understand experiences such as the urge to self-harm or the feeling of intense emotion, making sense of behaviours that are often simply regarded as symptoms of ‘disorder’. They also reveal the various way in which the longer term impacts of trauma can be supported and effectively managed, highlighting above all the importance of human connection. These moving and inspiring stories of painful experiences are shared in the spirit of openness and compassionate listening. The installation intentionally evokes the space of an imagined group encounter where people commit to holding a space for feelings and for respectful listening without judgement. ‘We’re just gonna call it all BPD’ is designed to be experienced as an immersive installation, in which 3 life-sized figures appear on screens that form a circle completed by 3 chairs in the viewing space. Premiered in the ensemble, Spaces Between People, for The Big Anxiety festival exhibition, Archives of Feeling, this intimate listening circle was intended to support viewers to ‘sit with’ difficult emotions. ‘We’re just gonna call it all BPD’ builds on research from an Australian Research Council [ARC] Linkage project led by Renata Kokanović, exploring narratives of people who have received a diagnosis of BPD (2)

Slowing down of spin glass correlation length growth: Simulations meet experiments

The growth of the spin glass correlation length has been measured as a function of the waiting time tw on a single crystal of CuMn (6 at. %), reaching values ¿~150 nm, larger than any other glassy correlation length measured to date. We find an aging rate dlntw/dln¿ larger than found in previous measurements, which evinces a dynamic slowing down as ¿ grows. Our measured aging rate is compared with simulation results by the Janus Collaboration. After critical effects are taken into account, we find excellent agreement with the Janus data

Thermally Activated Magnetization and Resistance Decay during Near Ambient Temperature Aging of Co Nanoflakes in a Confining Semi-metallic Environment

We report the observation of magnetic and resistive aging in a self assembled nanoparticle system produced in a multilayer Co/Sb sandwich. The aging decays are characterized by an initial slow decay followed by a more rapid decay in both the magnetization and resistance. The decays are large accounting for almost 70% of the magnetization and almost 40% of the resistance for samples deposited at 35 $^oC$. For samples deposited at 50 $^oC$ the magnetization decay accounts for $\sim 50$ of the magnetization and 50% of the resistance. During the more rapid part of the decay, the concavity of the slope of the decay changes sign and this inflection point can be used to provide a characteristic time. The characteristic time is strongly and systematically temperature dependent, ranging from $\sim1$x$10^2 s$ at 400K to $\sim3$x$10^5 s$ at 320K in samples deposited at $35 ^oC$. Samples deposited at 50 $^oC$ displayed a 7-8 fold increase in the characteristic time (compared to the $35 ^oC$ samples) for a given aging temperature, indicating that this timescale may be tunable. Both the temperature scale and time scales are in potentially useful regimes. Pre-Aging, Scanning Tunneling Microscopy (STM) reveals that the Co forms in nanoscale flakes. During aging the nanoflakes melt and migrate into each other in an anisotropic fashion forming elongated Co nanowires. This aging behavior occurs within a confined environment of the enveloping Sb layers. The relationship between the characteristic time and aging temperature fits an Arrhenius law indicating activated dynamics

Correspondence: Are Cognitive Functions Localizable? Colin Camerer et al. versus Marieke van Rooij and John G. Holden

The Fall 2011 issue of this journal published a two-paper section on “Neuroeconomics.” One paper, by Ernst Fehr and Antonio Rangel, clearly and concisely summarized a small part of the fast-growing literature. The second paper, “It’s about Space, It’s about Time, Neuroeconomics, and the Brain Sublime,” by Marieke van Rooij and Guy Van Orden, is beautifully written and enjoyable to read, but misleading in many critical ways. A number of economists and neuroscientists working at the intersection of the two fields shared our reaction and have signed this letter, as shown below. Some of the paper’s descriptions of empirical findings and methods in neuroeconomics are incomplete, badly out of date, or flatly wrong. In studies the authors describe in detail, their skeptical interpretations have often been refuted by published data, old and new, that they overlook

Slowing down of spin glass correlation length growth: Simulations meet experiments

The growth of the spin glass correlation length has been measured as a function of the waiting time tw on a single crystal of CuMn (6 at. %), reaching values ξ∼150 nm, larger than any other glassy correlation length measured to date. We find an aging rate dlntw/dlnξ larger than found in previous measurements, which evinces a dynamic slowing down as ξ grows. Our measured aging rate is compared with simulation results by the Janus Collaboration. After critical effects are taken into account, we find excellent agreement with the Janus data.</p

Superposition principle and nonlinear response in spin glasses

International audienceThe extended principle of superposition has been a touchstone of spin-glass dynamics for almost 30 years. The Uppsala group has demonstrated its validity for the metallic spin glass, CuMn, for magnetic fields H up to 10 Oe at the reduced temperature Tr=T/Tg=0.95, where Tg is the spin-glass condensation temperature. For H>10 Oe, they observe a departure from linear response which they ascribe to the development of nonlinear dynamics. The thrust of this paper is to develop a microscopic origin for this behavior by focusing on the time development of the spin-glass correlation length, ξ(t,tw;H). Here, t is the time after H changes, and tw is the time from the quench for T>Tg to the working temperature T until H changes. We connect the growth of ξ(t,tw;H) to the barrier heights Δ(tw) that set the dynamics. The effect of H on the magnitude of Δ(tw) is responsible for affecting differently the two dynamical protocols associated with turning H off (TRM, or thermoremanent magnetization) or on (ZFC, or zero-field-cooled magnetization). This difference is a consequence of nonlinearity based on the effect of H on Δ(tw). Superposition is preserved if Δ(tw) is linear in the Hamming distance Hd (proportional to the difference between the self-overlap qEA and the overlap q[Δ(tw)]). However, superposition is violated if Δ(tw) increases faster than linear in Hd. We have previously shown, through experiment and simulation, that the barriers Δ(tw) do increase more rapidly than linearly with Hd through the observation that the growth of ξ(t,tw;H) slows down as ξ(t,tw;H) increases. In this paper, we display the difference between the zero-field-cooled ξZFC(t,tw;H) and the thermoremanent magnetization ξTRM(t,tw;H) correlation lengths as H increases, both experimentally and through numerical simulations, corresponding to the violation of the extended principle of superposition in line with the finding of the Uppsala Group
