Population boundaries for compact white-dwarf binaries in LISA's amplitude-frequency domain

description: In an earlier investigation, we proposed population boundaries for both inspiralling and mass-transferring double white dwarf (DWD) systems in the distance independent "absolute" amplitude-frequency domain of the proposed space-based gravitational-wave (GW) detector, {\it LISA}. The degenerate zero temperature mass-radius (M-R) relationship of individual white dwarf stars that we assumed, in combination with the constraints imposed by Roche geometries, permits us to identify five key population boundaries for DWD systems in various phases of evolution. Here we use the non-zero entropy donor M-R relations of \cite{DB2003} to modify these boundaries for both DWD and neutron star-white dwarf (NSWD) binary systems. We find that the mass-transferring systems occupy a larger fraction of space in ``absolute'' amplitude-frequency domain compared to the simpler T=0 donor model. We also discuss how these boundaries are modified with the new evolutionary phases found by \cite{Deloyeetal2007}. In the initial contact phase, we find that the contact boundaries, which are the result of end of inspiral evolution, would have some width, as opposed to an abrupt cut-off described in our earlier T=0 model. This will cause an overlap between a DWDs $&$ NSWDs evolutionary trajectories, making them indistinguishable with only LISA observations within this region. In the cooling phase of the donor, which follows after the adiabatic donor evolution, the radius contracts, mass-transfer rate drops and slows down the orbital period evolution. Depending upon the entropy of the donor, these systems may then lie inside the fully degenerate T=0 boundaries, but LISA may be unable to detect these systems as they might be below the sensitivity limit or within the unresolved DWD background noise.

description: We evaluate in this work the hydrodynamic transport coefficients of a granular binary mixture in $d$ dimensions. In order to eliminate the observed disagreement (for strong dissipation) between computer simulations and previously calculated theoretical transport coefficients for a monocomponent gas, we obtain explicit expressions of the seven Navier-Stokes transport coefficients with the use of a new Sonine approach in the Chapman-Enskog theory. Our new approach consists in replacing, where appropriate in the Chapman-Enskog procedure, the Maxwell-Boltzmann distribution weight function (used in the standard first Sonine approximation) by the homogeneous cooling state distribution for each species. The rationale for doing this lies in the fact that, as it is well known, the non-Maxwellian contributions to the distribution function of the granular mixture become more important in the range of strong dissipation we are interested in. The form of the transport coefficients is quite common in both standard and modified Sonine approximations, the distinction appearing in the explicit form of the different collision frequencies associated with the transport coefficients. Additionally, we numerically solve by means of the direct simulation Monte Carlo method the inelastic Boltzmann equation to get the diffusion and the shear viscosity coefficients for two and three dimensions. As in the case of a monocomponent gas, the modified Sonine approximation improves the estimates of the standard one, showing again the reliability of this method at strong values of dissipation.

description: We demonstrate the DC-Kerr effect in PECVD Silicon-rich Nitride (SRN) and use it to demonstrate a third order nonlinear susceptibility, \c{hi}^((3)), as high as (6 +/- 0.58)x10-19 m2/v2. We employ spectral shift versus applied voltage measurements in a racetrack ring resonator as a tool by which to characterize the nonlinear susceptibilities of these films. In doing so we demonstrate a \c{hi}^((3)) larger than that of silicon and argue that PECVD SRN can provide a versatile platform for employing optical phase-shifters while maintain a low thermal budget using a deposition technique readily available in CMOS process flows.

description: Automated essay scoring (AES) is gaining increasing attention in the education sector as it significantly reduces the burden of manual scoring and allows ad hoc feedback for learners. Natural language processing based on machine learning has been shown to be particularly suitable for text classification and AES. While many machine-learning approaches for AES still rely on a bag-of-words (BOW) approach, we consider a transformer-based approach in this paper, compare its performance to a logistic regression model based on the BOW approach and discuss their differences. The analysis is based on 2,088 email responses to a problem-solving task, that were manually labeled in terms of politeness. Both transformer models considered in that analysis outperformed without any hyper-parameter tuning the regression-based model. We argue that for AES tasks such as politeness classification, the transformer-based approach has significant advantages, while a BOW approach suffers from not taking word order into account and reducing the words to their stem. Further, we show how such models can help increase the accuracy of human raters, and we provide a detailed instruction on how to implement transformer-based models for one's own purpose.

description: We consider the algorithmic question of choosing a subset of candidates of a given size $k$ from a set of $m$ candidates, with knowledge of voters' ordinal rankings over all candidates. We consider the well-known and classic scoring rule for achieving diverse representation: the Chamberlin-Courant (CC) or $1$-Borda rule, where the score of a committee is the average over the voters, of the rank of the best candidate in the committee for that voter; and its generalization to the average of the top $s$ best candidates, called the $s$-Borda rule. Our first result is an improved analysis of the natural and well-studied greedy heuristic. We show that greedy achieves a $\left(1 - \frac{2}{k+1}\right)$-approximation to the maximization (or satisfaction) version of CC rule, and a $\left(1 - \frac{2s}{k+1}\right)$-approximation to the $s$-Borda score. Our result improves on the best known approximation algorithm for this problem. We show that these bounds are almost tight. For the dissatisfaction (or minimization) version of the problem, we show that the score of $\frac{m+1}{k+1}$ can be viewed as an optimal benchmark for the CC rule, as it is essentially the best achievable score of any polynomial-time algorithm even when the optimal score is a polynomial factor smaller (under standard computational complexity assumptions). We show that another well-studied algorithm for this problem, called the Banzhaf rule, attains this benchmark. We finally show that for the $s$-Borda rule, when the optimal value is small, these algorithms can be improved by a factor of $\tilde Ω(\sqrt{s})$ via LP rounding. Our upper and lower bounds are a significant improvement over previous results, and taken together, not only enable us to perform a finer comparison of greedy algorithms for these problems, but also provide analytic justification for using such algorithms in practice.

description: Quantum annealing is a generic name of quantum algorithms to use quantum-mechanical fluctuations to search for the solution of optimization problem. It shares the basic idea with quantum adiabatic evolution studied actively in quantum computation. The present paper reviews the mathematical and theoretical foundation of quantum annealing. In particular, theorems are presented for convergence conditions of quantum annealing to the target optimal state after an infinite-time evolution following the Schroedinger or stochastic (Monte Carlo) dynamics. It is proved that the same asymptotic behavior of the control parameter guarantees convergence both for the Schroedinger dynamics and the stochastic dynamics in spite of the essential difference of these two types of dynamics. Also described are the prescriptions to reduce errors in the final approximate solution obtained after a long but finite dynamical evolution of quantum annealing. It is shown there that we can reduce errors significantly by an ingenious choice of annealing schedule (time dependence of the control parameter) without compromising computational complexity qualitatively. A review is given on the derivation of the convergence condition for classical simulated annealing from the view point of quantum adiabaticity using a classical-quantum mapping.

description: We present some general considerations on the properties of a two-component ultra-cold Fermi gas along the BEC-BCS crossover. It is shown that the interaction energy and the ground state energy can be written in terms of a single dimensionless function $h({ξ,τ})$, where $ξ=-(k_Fa_s)^{-1}$ and $τ=T/T_F$. The function $h(ξ,τ)$ incorporates all the many-body physics and naturally occurs in other physical quantities as well. In particular, we show that the RF-spectroscopy shift $\bar{\dø}(ξ,τ)$ and the molecular fraction $f_c(ξ,τ)$ in the closed channel can be expressed in terms of $h(ξ,τ)$ and thus have identical temperature dependence. The conclusions should have testable consequences in future experiments.

description: In many cases, transcriptional regulation involves the binding of transcription factors at sites on the DNA that are not immediately adjacent to the promoter of interest. This action at a distance is often mediated by the formation of DNA loops: Binding at two or more sites on the DNA results in the formation of a loop, which can bring the transcription factor into the immediate neighborhood of the relevant promoter. Though there have been a variety of insights into the combinatorial aspects of transcriptional control, the mechanism of DNA looping as an agent of combinatorial control in both prokaryotes and eukaryotes remains unclear. We use single-molecule techniques to dissect DNA looping in the lac operon. In particular, we measure the propensity for DNA looping by the Lac repressor as a function of the concentration of repressor protein and as a function of the distance between repressor binding sites. As with earlier single-molecule studies, we find (at least) two distinct looped states and demonstrate that the presence of these two states depends both upon the concentration of repressor protein and the distance between the two repressor binding sites. We find that loops form even at interoperator spacings considerably shorter than the DNA persistence length, without the intervention of any other proteins to prebend the DNA. The concentration measurements also permit us to use a simple statistical mechanical model of DNA loop formation to determine the free energy of DNA looping, or equivalently, the J-factor for looping.

DL/DIS Lecture Slides - Santa Clara Chapter, May 4, 2020, Dr. Arianne Hinds
The emergence of advanced imaging display technologies, either existing or highly anticipated, has motivated new ways to contemplate the production and service delivery of media in order to enable new and immersive user experiences. Whether it be VR gaming, telepresence, spatial computing, lean-back viewing, or experiencing the reality of a futuristic holodeck scene, the applications facilitated by emerging advanced-imaging displays have begun to test the limits of existing 2D video workflows and formats. Moreover, historically, the minimal “must haves” for any new display to succeed in the marketplace includes a sufficient number of hours (about 5000) of supporting content, a well adopted distribution format to drive the display, and the accessibility of the display itself to consumers. This presentation summarizes the history of media leading to the emergence of immersive media and displays, and considers the impacts of the emerging ecosystem on media production, standards, and distribution workflows.

description: In this article, I analyze the symmetries and degeneracies of electron eigenstates in a commensurate collinear antiferromagnet. In a magnetic field transverse to the staggered magnetization, a hidden anti-unitary symmetry protects double degeneracy of the Bloch eigenstates at a special set of momenta. In addition to this `Kramers degeneracy' subset, the manifold of momenta, labeling the doubly degenerate Bloch states in the Brillouin zone, may also contain an `accidental degeneracy' subset, that is not protected by symmetry and that may change its shape under perturbation. These degeneracies give rise to a substantial momentum dependence of the transverse g-factor in the Zeeman coupling, turning the latter into a spin-orbit interaction. I discuss a number of materials, where Zeeman spin-orbit coupling is likely to be present, and outline the simplest properties and experimental consequences of this interaction, that may be relevant to systems from chromium to borocarbides, cuprates, hexaborides, iron pnictides, as well as organic and heavy fermion conductors.

Cerebral energy metabolism in mallard ducks during apneic asphyxia the role of oxygen conservation
Creators: name: Bryan, Robert Maurice
Publisher: name: University of British Columbia
Year: 2010

description: Cerebral energy metabolism during apneic asphyxia and steady state hypoxia was compared in ducks and chickens; ducks tolerate apneic asphyxia 3-8 times longer than chickens. Fluctuations in the reduced form of respiratory chain nicotinamide adenine dinucleotide (NADH) were monitored from the left cerebral hemisphere by a noninvasive fluorometric technique and used as an indicator of mitochondrial hypoxia. Electroencephalogram (EEG) and surface PO₂ were recorded from the right hemisphere. Forced dives of 4-7 minutes duration on restrained ducks were characterized by bradycardia and an accumulation of NADH which increased throughout the diving period. NADH returned to the preasphyxic level when breathing was resumed. In later experiments asphyxia was produced by stopping artificial ventilation in paralyzed ducks. Asphyxia produced by this means caused similar changes in the measured variables (heart rate, blood pressure, NADH fluorescence, and EEG) to those obtained in forced submergence of nonparalyzed ducks. NADH fluorescence was expressed in arbitrary units (AU) where 100 AU was defined as the fluorescence change from normoxia to anoxia. After 1 minute of asphyxia NADH fluorescence in-creased by 37 AU ± 3.60 SEM (n = 54) in paralyzed chickens and 8 AU ± 1.41 SEM (n = 55) in paralyzed ducks. After 2 minutes the fluorescence increased by only 15 AU - 1.95 SEM in ducks. Both species showed an isoelectric EEG when fluorescence increased by approximately 35 AU indicating that anaerobic ATP production in ducks did not maintain brain function (EEG) for a greater accumulation of respiratory chain NADH. At a given decrease in tissue PO₂ ducks and chickens showed the same level of NADH increase indicating that both species are equally dependent on tissue PO₂ for the maintenance of redox state. Furthermore, the inhibition of cardiovascular adjustments by atropine in ducks caused NADH to increase faster during apneic asphyxia than in nonatropinized ducks. I conclude that the oxygen conserving cardiovascular adjustments are responsible for the increased cerebral tolerance to apneic asphyxia in ducks without any involvement of biochemical mechanisms.
Thermal Pressures in the Interstellar Medium away from Stellar Environments

description: Interstellar thermal pressures can be measured using C I absorption lines that probe the pressure-sensitive populations of the fine-structure levels of its ground state. In a survey of C I absorption toward Galactic hot stars, Jenkins & Tripp (2011) found evidence of small amounts ($\sim 0.05\%$) of gas at high pressures ($p/k \gg 10^4{\rm cm^{-3}K}$) mixed with a more general presence of lower pressure material exhibiting a log normal distribution that spanned the range $10^3 \lesssim p/k \lesssim 10^4{\rm cm^{-3}K}$. In this paper, we study Milky Way C I lines in the spectra of extragalactic sources instead of Galactic stars and thus measure the pressures without being influenced by regions where stellar mass loss and H II region expansions could create localized pressure elevations. We find that the distribution of low pressures in the current sample favors slightly higher pressures than the earlier survey, and the fraction of gaseous material at extremely high pressures is about the same as that found earlier. Thus we conclude that the earlier survey was not appreciably influenced by the stellar environments, and the small amounts of high pressure gas indeed exist within the general interstellar medium.

description: We introduce a one-parameter deformation of the Wishart-Laguerre or chiral ensembles of positive definite random matrices with Dyson index beta=1,2 and 4. Our generalised model has a fat-tailed distribution while preserving the invariance under orthogonal, unitary or symplectic transformations. The spectral properties are derived analytically for finite matrix size NxM for all three beta, in terms of the orthogonal polynomials of the standard Wishart-Laguerre ensembles. For large-N in a certain double scaling limit we obtain a generalised Marcenko-Pastur distribution on the macroscopic scale, and a generalised Bessel-law at the hard edge which is shown to be universal. Both macroscopic and microscopic correlations exhibit power-law tails, where the microscopic limit depends on beta and the difference M-N. In the limit where our parameter governing the power-law goes to infinity we recover the correlations of the Wishart-Laguerre ensembles. To illustrate these findings the generalised Marcenko-Pastur distribution is shown to be in very good agreement with empirical data from financial covariance matrices.

description: The two-parameter distribution known as exponential-Poisson (EP) distribution, which has decreasing failure rate, was introduced by Kus (2007). In this paper we generalize the EP distribution and show that the failure rate of the new distribution can be decreasing or increasing. The failure rate can also be upside-down bathtub shaped. A comprehensive mathematical treatment of the new distribution is provided. We provide closed-form expressions for the density, cumulative distribution, survival and failure rate functions; we also obtain the density of the $i$th order statistic. We derive the $r$th raw moment of the new distribution and also the moments of order statistics. Moreover, we discuss estimation by maximum likelihood and obtain an expression for Fisher's information matrix. Furthermore, expressions for the Rényi and Shannon entropies are given and estimation of the stress-strength parameter is discussed. Applications using two real data sets are presented.

In particular, by mapping the equations of front motion onto the dynamics of a dissipative driven oscillator, an analytical criterion for front pinning is derived, under the condition of diluteness of the coating spots. The criterion is tested against two dimensional Lattice Boltzmann simulations, and found to provide satisfactory agreement as long as the width of the front interface remains much thinner than the typical heterogeneity scale of the chemical coating.

description: We perform on-the-fly non-adiabatic molecular dynamics simulations using the symmetrical quasi-classical (SQC) approach with the recently suggested molecular Tully models: ethylene and fulvene. We attempt to provide benchmarks of the SQC methods using both the square and the triangle windowing schemes as well as the recently proposed electronic zero-point-energy correction scheme (so-called the gamma correction). We use the quasi-diabatic propagation scheme to directly interface the diabatic SQC methods with adiabatic electronic structure calculations. Our results showcase the drastic improvement of the accuracy by using the trajectory-adjusted gamma-corrections, which outperform the widely used trajectory surface hopping method with decoherence corrections. These calculations provide useful and non-trivial tests to systematically investigate the numerical performance of various diabatic quantum dynamics approaches, going beyond simple diabatic model systems that have been used as the major workhorse in the quantum dynamics field. At the same time, these available benchmark studies will also likely foster the development of new quantum dynamics approaches based on these techniques.

description: The goal of the research was to assess the impact of e-Human Resource Management (E-HRM) on organizational performance. There were six independent variables (e-Recruitment &Selection, e-Learning &Training, e-performance appraisal, e-Communication, e-compensation management, and e-Productivity) identified from an in-depth literature review and a conceptual framework to assess the impact of E-HRM on organizational performance was proposed. Data was gathered through the use of a self-structured questionnaire from 241 a wide range of firms' employees in the United Arab Emirates and was analyzed using SPSS version 22.0. A multiple regression was done to predict the organizational performance from all six independent factors. The finding reveals that there is statistically significant positive connection between organizational performance and e-HRM indicators. As a result, it is recommended that there should be a list of standards for every industry in the United Arab Emirates and automated e-HR processes that contribute to increased productivity and improved organizational performance.

STEM Teacher Education

description: This White Paper presents an ambitious vision for the type of education system required to prepare learners for the future. It contains a strong focus on integrated science, technology, engineering and mathematics (STEM) education, essential for developing the necessary competences to thrive in our complex, ever-changing world. Within such a holistic and equitable education system, these learners will be equipped to realise a planet with thriving and sustainable societies, economies and environment. We posit that teachers are the catalyst to realising this vision and ensuring that effective, sustainable systematic change happens. However, they cannot do it alone and will need the support of a range of stakeholders and actors to create this effective learning ecosystem. Considering this and also the point that the most impactful moment to influence the teachers of the future is during their initial teacher education - when they are fully immersed in the processes and practices of active, situated learning - designing an intervention that focused on working with initial teachers seemed the logical starting point. If these teachers are to design authentic learning experiences which integrate core STEM competences within real-world contexts, we believe it is essential that they have first hand experience in these contexts themselves. Only with such a rounded experience, will they be in a position to inspire truly innovative STEM learning in their classrooms. These ideas are what led to the development of the STEM Teacher Internship (STInt) Programme, which encapsulates clearly how building partnerships between teacher educators, student teachers and industry can play a part in shaping the shared futures of the next generation of Irish students. This White Paper argues that two major challenges are:
 – Inequities in education broadly, and specifically issues of diversity, equity and inclusion in STEM education, which lead to inequities in STEM professions and careers.
 – The need for consensus between research/higher education, policy and practice when it comes to STEM education, and the need for capacity-building measures to support teachers to deliver integrated STEM education. We propose two recommendations for actions to address these challenges:
 - Build and deepen teachers’ understanding of integrated STEM education through immersive professional experiences in real-world STEM contexts.
 - Develop and strengthen the connections across and between actors within the STEM learning ecosystem to improve learner outcomes.

description: In this work, global search for crystal structures of ternary Mg-Sc-H hydrides (Mg$_x$Sc$_y$H$_z$) under high pressure ($100 \le P \le 200$ GPa) were performed using the evolutionary algorithm and first-principles calculations. Based on them, we computed the thermodynamic convex hull and pressure-dependent phase diagram of Mg$_x$Sc$_y$H$_z$ for $z/(x+y) < 4$. We have identified the stable crystal structures of four thermodynamically stable compounds with the higher hydrogen content, i.e., $R\bar{3}m$-MgScH$_{6}$, $C2/m$-Mg$_{2}$ScH$_{10}$, $Immm$-MgSc$_{2}$H$_{9}$ and $Pm\bar{3}m$-Mg(ScH$_{4}$)$_{3}$. Their superconducting transition temperatures were computationally predicted by the McMillan-Allen-Dynes formula combined with first-principles phonon calculations. They were found to exhibit superconductivity; among them, $R\bar{3}m$-MgScH$_{6}$ was predicted to have the highest $T_{c}$ (i.e. 23.34 K) at 200 GPa.

description: The dynamical-mean-field method is applied to investigate the transport properties of heterostructures consisting of a strongly-correlated electron system connected to metallic leads. The spectral function inside the correlated region is sensitive to the change of the interaction strength and bias voltage. Because of this sensitivity, current vs voltage characteristics of such heterostructures are rather nonlinear regardless of the detail of the potential profile inside the correlated region. The electronic properties such as the double occupancy are also changed by the bias voltage.

Freedom and responsibility
Creators: name: Baugh, Bruce
Publisher: name: University of British Columbia
Year: 2010

description: This thesis shows the ways in which the concepts of freedom and responsibility are related, and how indeed they illuminate each other. In Part One, it is shown that both are based on a concept of action, and it is thus with an analysis of action that a theory of freedom and responsibility must begin. Actions are first differentiated from events, so that conditions which must obtain from an event to be an action are specified. The concept of responsibility may then be used to illuminate action by showing how excuses indicate ways in which actions can fail. From this analysis, an analysis of action in the full sense emerges, namely, that an action in the full or unqualified sense is that to which no excuses are applicable. Action in the full sense is thus linked to responsibility in the full sense. The analysis of action shows that the breakdown of an action is the loss of control over its effects, and action in the full sense thus obtains where no breakdown occurs. Conscious control over an action is the control of an action's effects, which is the realization of intentions, and the control of intentions, which is what may be analyzed as rationality. Conscious control over an action, or agency, constitutes freedom on the plane of individual action. Thus, from the concept of responsibility emerges a concept of action and of agency which indicates what freedom is. Yet, it is the actual structure of action upon which the action of responsibility rests. The theory of freedom is defined in Part Two against the incompatibilist position that if determinism is true, neither freedom nor responsibility exist. It is shown that causal determinism does not rule out actions being free in the sense required for an individual to be responsible; for them as a theory of action shows that it is not an action's being caused but the nature of its causes which makes it free or unfree. If the action is caused so that it is in the conscious control of the agent, it is free. The rest of Part Two examines moral practices such as praise and blame in light of the limits determinism places on them. It is necessary to show what rational or justifiable grounds there could be for practices such as praising and blaming in any theory of freedom and responsibility. Part Three shows that agency, or control over an action, is extendable over the values upon which actions are based. Control over values is achieved by the individual consciously choosing values in awareness of being responsible for those choices and values. What the Existentialists call "Authenticity" is thus a fuller degree of freedom and of agency. This analysis of authenticity does not focus on how authenticity is a response to a value question posed by nihilism; but on how authenticity is an extension of our regular concepts of freedom and responsibility. It is shown that authenticity, when it is accompanied by full agency (as that notion is developed in Part One) is freedom and responsibility in the highest degree.

description: We present an experimental study of the infrared conductivity, transmission, and reflection of a gated bilayer graphene and their theoretical analysis within the Slonczewski-Weiss-McClure (SWMc) model. The infrared response is shown to be governed by the interplay of the interband and the intraband transitions among the four bands of the bilayer. The position of the main conductivity peak at the charge neutrality point is determined by the interlayer tunneling frequency. The shift of this peak as a function of the gate voltage gives information about less known parameters of the SWMc model, in particular, those responsible for the electron-hole and sublattice asymmetries. These parameter values are shown to be consistent with recent electronic structure calculations for the bilayer graphene and the SWMc parameters commonly used for the bulk graphite.

description: The MAGIC collaboration has recently reported the discovery of gamma-ray emission from the binary system LS I +61 303 in the TeV energy region. Here we present new observational results on this source in the energy range between 300 GeV and 3 TeV. In total 112 hours of data were taken between September and December 2006 covering 4 orbital cycles of this object. This large amount of data allowed us to produce an integral flux light curve covering for the first time all orbital phases of LS I +61 303. In addition, we also obtained a differential energy spectrum for two orbital phase bins covering the phase range 0.5

description: We consider the generation of gravitational waves by primordial helical inverse cascade magnetohydrodynamic (MHD) turbulence produced by bubble collisions at the electroweak phase transition. We extend the previous study \cite{kgr08} by considering both currently discussed models of MHD turbulence. For popular electroweak phase transition parameter values, the generated gravitational wave spectrum is only weakly dependent on the MHD turbulence model. Compared to the unmagnetized electroweak phase transition case, the spectrum of MHD-turbulence-generated gravitational waves peaks at lower frequency with larger amplitude and can be detected by the proposed Laser Interferometer Space Antenna

Between Visibility and Media Performativity. The Role of Interface and Gesturality in Desktop Cinema
Creators: name: , Gabriele
Publisher: name: Cinéma & Cie. Film and Media Studies Journal
Year: 2021

description: This article aims to investigate desktop films as ‘meta-media’ audiovisual forms and to analyse their aesthetics and their meta-reflective potential in the broader framework of contemporary visual and media culture. Screens and interfaces, re-mediated into these films, constitute a second-level media space into the filmic space. They are the only space visually accessible to the spectator, whereby the characters’ gesturality emerges as a form of performing relationship with digital technology, as a posture or a more general engagement with the (media) environment, as an ‘operational trace’ on the screen. Resulting from this visual and narrative structure is the centrality of ‘media performativity’, a concept that will be widely problematized in this article on a theoretical level and analysed as a behavioural pattern that characterizes our daily interaction with the screens surrounding us, as a part of an eco-media system in which action (of the user) and reaction (of the interface) are intervolved and entangled. The concept of media performativity relies on the idea that the individual is no longer separate from the medium throughout the mediation process but is instead deeply and radically involved in the medium itself.

European Neurodivergent Detectives and the Politics of Autism Representation
Creators: name: , Gabriele
Publisher: name: Cinéma & Cie. Film and Media Studies Journal
Year: 2021

description: One of the most original, recent contributions of contemporary European seriality to the crime genre has been the introduction of a notable number of detectives repeatedly diagnosed as autistic by autistic online communities. Titles such as the Millennium saga, Sherlock, Forbrydelsen, Bron/Broen, and, more recently, Astrid et Raphaëlle, are all widely debated within autistic online communities. This article investigates the unique critical perspective brought by the autistic parlance on these popular products, through a survey of blogs, social networks, fanfiction, and videos, in English and French. The analysis of this material reveals that there is a whole spectrum of different opinions among autists when it comes to their approval, or disapproval, of media representations of neurodiversity, oscillating between complaints for the persistence of the ‘savant autist’ stereotype and a grateful appreciation of the effort to portray the condition in positive and empowering ways. Most of the comments reflect the stances of the neurodiversity movement and the complex context of autism advocacy, by which autistic individuals reclaim the right to speak for themselves and stand up to fight for a more inclusive society.
