The educational turn in art: rewriting the hidden curriculum

Around 2006, the art world developed a prolonged fascination with questions of education, pedagogy and the art school. ‘The Educational Turn’ (Rogoff, 2008) as it became known, produced a plethora of artistic and curatorial practices that engage with educational paradigms and problematics. Prompted in part by the European Union Bologna Process, the Educational Turn provided a critique of education as one-directional knowledge transfer, and the framing of education as a commercialised industry, reduced to the utilitarianism of training for working life. At the same time, it established ‘education’ as a thematic for the art world, in most cases divorced from its capacity for producing change in the fields of art or education. This article asks, what is the hidden curriculum (Illich) of this Educational Turn? Drawing from the writings of Colin Crouch, Wolfgang Streeck and Paulo Virno among others, it suggests that such ‘turns’ without a vital link to the realm of action, contribute to the broader problematic of public programming without a public sphere, through which formerly democratic institutions (like art galleries) operate as shells in a capitalist environment that is increasingly incompatible with democracy. We read The Education Turn here as a missed opportunity to re-shape art curricula and institutions, to develop a movement to oppose the Bologna Accord and the brutal changes imposed on art education through austerity politics. Finally, we argue - citing the writings of Paulo Friere, the mutualist movements in Europe of the 18th and 19th centuries, the educational experiments of Celestin Freinet in and Fernand Oury in France in the 1950s and the pedagogies of feminist and post-colonial struggle - for a deeper connection to radical education genealogies and their contemporary counterparts in contemporary public programming today

The New Horizon Run Cosmological N-Body Simulations

We present two large cosmological N-body simulations, called Horizon Run 2 (HR2) and Horizon Run 3 (HR3), made using 6000^3 = 216 billions and 7210^3 = 374 billion particles, spanning a volume of (7.200 Gpc/h)^3 and (10.815 Gpc/h)^3, respectively. These simulations improve on our previous Horizon Run 1 (HR1) up to a factor of 4.4 in volume, and range from 2600 to over 8800 times the volume of the Millennium Run. In addition, they achieve a considerably finer mass resolution, down to 1.25x10^11 M_sun/h, allowing to resolve galaxy-size halos with mean particle separations of 1.2 Mpc/h and 1.5 Mpc/h, respectively. We have measured the power spectrum, correlation function, mass function and basic halo properties with percent level accuracy, and verified that they correctly reproduce the LCDM theoretical expectations, in excellent agreement with linear perturbation theory. Our unprecedentedly large-volume N-body simulations can be used for a variety of studies in cosmology and astrophysics, ranging from large-scale structure topology, baryon acoustic oscillations, dark energy and the characterization of the expansion history of the Universe, till galaxy formation science - in connection with the new SDSS-III. To this end, we made a total of 35 all-sky mock surveys along the past light cone out to z=0.7 (8 from the HR2 and 27 from the HR3), to simulate the BOSS geometry. The simulations and mock surveys are already publicly available at http://astro.kias.re.kr/Horizon-Run23/.Comment: 18 pages, 10 figures. Added clarification on Fig 6.

On the selection of control lines for x charts on an economic basis

This paper proposes a procedure for determining, through simulation, the multiple of sigma that should be used to maintain the current control of a process. This is done by minimizing the cost of the operation of the control chart program and any income loss which may accure from the interaction of the causal variables

Spontaneous chirality via long-range electrostatic forces

We consider a model for periodic patterns of charges constrained over a cylindrical surface. In particular we focus on patterns of chiral helices, achiral rings or vertical lamellae, with the constraint of global electroneutrality. We study the dependence of the patterns' size and pitch angle on the radius of the cylinder and salt concentration. We obtain a phase diagram by using numerical and analytic techniques. For pure Coulomb interactions, we find a ring phase for small radii and a chiral helical phase for large radii. At a critical salt concentration, the characteristic domain size diverges, resulting in macroscopic phase segregation of the components and restoring chiral symmetry. We discuss possible consequences and generalizations of our model.Comment: Revtex, 4 pages, 4 figure

Peer Influence and Attraction to Interracial Romantic Relationships

The present research examined the effect of social influence on White, heterosexual individuals’ attraction to targets of varying races (White vs. Black) in two college student samples from the United States (one that leaned politically liberal and one that leaned politically conservative). Using a within-subjects experimental design, participants were given artificial peer evaluation data (positive, negative, or none) before providing ratings of attractiveness and dating interest for a series of targets. In both samples, positive information was associated with greater levels of attraction and dating interest than negative information, regardless of target race. Within the conservative sample, participants reported greater attraction toward and more dating interest in White targets relative to Black targets, while in the liberal sample, participants’ ratings of targets did not significantly differ from one another. These findings suggest that social influence can affect perceptions of attractiveness even in very different political climates.Psycholog

Palladium(II) complexes of a bridging amine bis(phenolate) ligand featuring κ² and κ³ coordination modes

Bidentate and tridentate coordination of a 2,4-di-tert-butyl-substituted bridging amine bis­(phenolate) ligand to a palladium(II) center are observed within the same crystal structure, namely di­chlorido­({6,6′-[(ethane-1,2-diylbis(methyl­aza­nedi­yl)]bis­(methyl­ene)}bis­(2,4-di-tert-butyl­phenol))palladium(II) chlorido­(2,4-di-tert-butyl-6-{[(2-{[(3,5-di-tert-butyl-2-hy­droxy­phen­yl)meth­yl](meth­yl)amino}­eth­yl)(meth­yl)amino]­meth­yl}phenolato)palladium(II) methanol 1.685-solvate 0.315-hydrate, [PdCl2(C34H56N2O2)][PdCl(C34H55N2O2)]·1.685CH3OH·0.315H2O. Both complexes exhibit a square-planar geometry, with unbound phenol moieties participating in inter­molecular hydrogen bonding with co-crystallized water and methanol. The presence of both κ2 and κ3 coordination modes arising from the same solution suggest a dynamic process in which phenol donors may coordinate or dissociate from the metal center, and offers insight into catalyst speciation throughout Pd-mediated processes. The unit cell contains di­chlorido­({6,6′-[(ethane-1,2-diylbis(methyl­aza­nedi­yl)]bis­(methyl­ene)}bis­(2,4-di-tert-butyl­phenol))palladium(II), {(L2)PdCl2}, and chlorido­(2,4-di-tert-butyl-6-{[(2-{[(3,5-di-tert-butyl-2-hy­droxy­phen­yl)meth­yl](methyl)amino}eth­yl)(meth­yl)amino]­meth­yl}phenolato)palladium(II), {(L2X)PdCl}, mol­ecules as well as fractional water and methanol solvent mol­ecules
