The Menon-Ĺ˝iĹžek Debate: âThe Tale of the (Never-marked) (But secretly coded) Universal and the (Always marked) Particular . . .â
On occasion of his first lecture tour of India in 2010, Ĺ˝iĹžek sparked off a debate with Nivedita Menon, a leading postcolonial feminist scholar. The debate revolves around Menon\u27s contention that Ĺ˝iĹžek\u27s emphasis on European, Christian Universalism as the most proactive model for countering capitalism is ignorant of the heteroglossiac postcolonial histories of South Asia. Menon\u27s response (âThe Two Ĺ˝iĹžeksâ) suggests that what Ĺ˝iĹžek appears to be missing is knowledge of the fallibility of Eurocentric discourses in negotiating the colonial and postcolonial situations particular to the subcontinent. Though Ĺ˝iĹžek\u27s debates with Badiou and Butler are well known, few outside India are aware of the Menon-Ĺ˝iĹžek debate. This paper will occasion this little known debate to consider some of the major points raised by Menon against the applicability of Ĺ˝iĹžek\u27s theoretical arguments toward reading and understanding postcolonial politics and culture
âYou Should Pray I Choose the Latterâ: Rioting, Violence, & Jouissance
In the climactic scene from the film The Great Debaters (2007), James L. Framer Jr. (Denzel Whitaker), speaking for the motion âResolved: Civil Disobedience is a Moral weapon in the fight for Justice,â rebuts the opponent team from Harvard University and clinches a win for his team, Wiley College, with the following words:
St. Augustine said an unjust law is no law at all, which means I have a right, even a duty, to resist. With violence or civil disobedience. You should pray I choose the latter.
(1:52:20 â 1:55:45)
Farmer Jr.âs words receive a standing ovation from the predominantly white, upper class, urban and educated on-screen audience, and cues audiences watching the film to two things. First, and unsurprisingly, it references Wiley Collegeâs historic win against Harvard that was announced moments later in the film. And, secondly, it reasserts what today has become a culture-clichĂŠ, namely, civil disobedience or nonviolent protests against social injustice are moral, even desired, compared to violent demonstrations that benefit no one. In so doing The Great Debaters becomes more than a partly fictionalized account of an historic event â Wiley College was the first historically Black college from Jim Crow South to win a regional debate championship (they defeated the University of Southern California depicted as Harvard in the film) â, it functions rather as an ideological tool teaching its viewers about not only what social changes to desire but also how to act upon realizing this desire for social change. Simply put, mass movements demanding social changes are necessary, even required, but these must always remain nonviolent. The choice given in Farmer Jr.âs last sentence â âYou should pray I choose the latterâ â is therefore not so much a choice as it is an affirmation of nonviolent civil disobedience as the only moral form of protest against unjust social laws

Forward rapidity J/Ď production as a function of charged-particle multiplicity in pp collisions at = 5.02 and 13 TeV
The production of J/Ď is measured as a function of charged-particle multiplicity at forward rapidity in proton-proton (pp) collisions at center-of-mass energies âs = 5.02 and 13 TeV. The J/Ď mesons are reconstructed via their decay into dimuons in the rapidity interval (2.5 < y < 4.0), whereas the charged-particle multiplicity density (dNch/dΡ) is measured at midrapidity (|Ρ| < 1). The production rate as a function of multiplicity
is reported as the ratio of the yield in a given multiplicity interval to the multiplicity-integrated one. This observable shows a linear increase with charged-particle multiplicity normalized to the corresponding average value for inelastic events (dNch/dΡ/ădNch/dΡă),
at both the colliding energies. Measurements are compared with available ALICE results at midrapidity and theoretical model calculations. First measurement of the mean transverse momentum (ăpTă) of J/Ď in pp collisions exhibits an increasing trend as a function
of dNch/dΡ/ădNch/dΡă showing a saturation towards high charged-particle multiplicities
Neutral to charged kaon yield fluctuations in Pb â Pb collisions at sNN=2.76 TeV
We present the first measurement of event-by-event fluctuations in the kaon sector in Pb â Pb collisions
at âsNN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used
to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as
the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges.
While the correlator νdyn[K+, Kâ ] exhibits a scaling approximately in inverse proportion of the charged
particle multiplicity, νdyn[K0
S , KÂą ] features a significant deviation from such scaling. Within uncertainties,
the value of νdyn[K0S , K¹ ] is independent of the selected transverse momentum interval, while it exhibits
a pseudorapidity dependence. The results are compared with HIJING, AMPT and EPOSâLHC predictions,
and are further discussed in the context of the possible production of disoriented chiral condensates in
central Pb â Pb collisions
Light (anti)nuclei production in Pb-Pb collisions at sNN=5.02Â TeV
The measurement of the production of deuterons, tritons and 3 He and their antiparticles in Pb-Pb collisions
at âs NN = 5.02 TeV is presented in this article. The measurements are carried out at midrapidity (|y| <
0.5) as a function of collision centrality using the ALICE detector. The pT -integrated yields, the coalescence
parameters and the ratios to protons and antiprotons are reported and compared with nucleosynthesis models. The
comparison of these results in different collision systems at different center-of-mass collision energies reveals a
suppression of nucleus production in small systems. In the Statistical Hadronisation Model framework, this can
be explained by a small correlation volume where the baryon number is conserved, as already shown in previous
fluctuation analyses. However, a different size of the correlation volume is required to describe the proton yields
in the same data sets. The coalescence model can describe this suppression by the fact that the wave functions
of the nuclei are large and the fireball size starts to become comparable and even much smaller than the actual
nucleus at low multiplicities
Inclusive and multiplicity dependent production of electrons from heavy-flavour hadron decays in pp and p-Pb collisions
Measurements of the production of electrons from heavy-flavour hadron decays in pp collisions at root s = 13 TeV at midrapidity with the ALICE detector are presented down to a transverse momentum (p(T)) of 0.2 GeV/c and up to p(T) = 35 GeV/c, which is the largest momentum range probed for inclusive electron measurements in ALICE. In p-Pb collisions, the production cross section and the nuclear modification factor of electrons from heavy-flavour hadron decays are measured in the p(T) range 0.5 < p(T) < 26 GeV/c at root s(NN) = 8.16 TeV. The nuclear modification factor is found to be consistent with unity within the statistical and systematic uncertainties. In both collision systems, first measurements of the yields of electrons from heavy-flavour hadron decays in different multiplicity intervals normalised to the multiplicity-integrated yield (self-normalised yield) at midrapidity are reported as a function of the self-normalised charged-particle multiplicity estimated at midrapidity. The self-normalised yields in pp and p-Pb collisions grow faster than linear with the self-normalised multiplicity. A strong p(T) dependence is observed in pp collisions, where the yield of high-p(T) electrons increases faster as a function of multiplicity than the one of low-p(T) electrons. The measurement in p-Pb collisions shows no p(T) dependence within uncertainties. The self-normalised yields in pp and p-Pb collisions are compared with measurements of other heavy-flavour, light-flavour, and strange particles, and with Monte Carlo simulations
Coherent J/Ď and Ď photoproduction at midrapidity in ultra-peripheral PbâPb collisions at âsNN = 5.02 TeV
The coherent photoproduction of J/ĎJ/Ď and Ďâ˛ĎⲠmesons was measured in ultra-peripheral PbâPb collisions at a center-of-mass energy sNNââââ = 5.02sNN = 5.02 TeV with the ALICE detector. Charmonia are detected in the central rapidity region for events where the hadronic interactions are strongly suppressed. The J/ĎJ/Ď is reconstructed using the dilepton (l+lâl+lâ) and protonâantiproton decay channels, while for the Ďâ˛ĎⲠthe dilepton and the l+lâĎ+Ďâl+lâĎ+Ďâ decay channels are studied. The analysis is based on an event sample corresponding to an integrated luminosity of about 233 Îźbâ1Îźbâ1. The results are compared with theoretical models for coherent J/ĎJ/Ď and Ďâ˛ĎⲠphotoproduction. The coherent cross section is found to be in a good agreement with models incorporating moderate nuclear gluon shadowing of about 0.64 at a Bjorken-x of around 6Ă10â46Ă10â4, such as the EPS09 parametrization, however none of the models is able to fully describe the rapidity dependence of the coherent J/ĎJ/Ď cross section including ALICE measurements at forward rapidity. The ratio of Ďâ˛ĎⲠto J/ĎJ/Ď coherent photoproduction cross sections was also measured and found to be consistent with the one for photoproduction off protons.publishedVersio
Production of pions, kaons, and protons as a function of the relative transverse activity classifier in pp collisions at = 13 TeV
Abstract: The production of ĎÂą, KÂą, and ( p )p is measured in pp collisions at âs = 13 TeV
in different topological regions of the events. Particle transverse momentum (pT) spectra are
measured in the âtowardâ, âtransverseâ, and âawayâ angular regions defined with respect
to the direction of the leading particle in the event. While the toward and away regions
contain the fragmentation products of the near-side and away-side jets, respectively, the
transverse region is dominated by particles from the Underlying Event (UE). The relative
transverse activity classifier, RT = NT/ăNTă, is used to group events according to their UE
activity, where NT is the measured charged-particle multiplicity per event in the transverse
region and ăNTă is the mean value over all the analysed events. The first measurements
of identified particle pT spectra as a function of RT in the three topological regions are
reported. It is found that the yield of high transverse momentum particles relative to the
RT-integrated measurement decreases with increasing RT in both the toward and the away
regions, indicating that the softer UE dominates particle production as RT increases and
validating that RT can be used to control the magnitude of the UE. Conversely, the spectral
shapes in the transverse region harden significantly with increasing RT. This hardening
follows a mass ordering, being more significant for heavier particles. Finally, it is observed
that the pT-differential particle ratios (p + p )/(Ď+ + Ďâ) and (K+ + Kâ)/(Ď+ + Ďâ) in
the low UE limit (RT â 0) approach expectations from Monte Carlo generators such as
PYTHIA 8 with Monash 2013 tune and EPOS LHC, where the jet-fragmentation models
have been tuned to reproduce e+eâ results
Measurement of the production of (anti)nuclei in pâPb collisions at sNN=8.16TeV
Measurements of (anti)proton, (anti)deuteron, and (anti)3He production in the rapidity range -1 > y > 0 as a function of the transverse momentum and event multiplicity in pâPb collisions at a center-of-mass energy per nucleonânucleon pair sqrt(sNN) = 8.16 TeV are presented. The coalescence parameters B2 and B3, measured as a function of the transverse momentum per nucleon and of the mean charged-particle multiplicity density, confirm a smooth evolution from low to high multiplicity across different collision systems and energies. The ratios between (anti)deuteron and (anti)3He yields and those of (anti)protons are also reported as a function of the mean charged-particle multiplicity density. A comparison with the predictions of the statistical hadronization and coalescence models for different collision systems and center-of-mass energies favors the coalescence description for the deuteron-to-proton yield ratio with respect to the canonical statistical model
