description: Star-forming galaxies which are too faint to be detected individually produce intensity fluctuations in the cosmic background light. This contribution needs to be taken into account as a foreground when using the primordial signal to constrain cosmological parameters. The extragalactic fluctuations are also interesting in their own right as they depend on the star formation history of the Universe and the way in which this connects with the formation of cosmic structure. We present a new framework which allows us to predict the occupation of dark matter haloes by star-forming galaxies and uses this information, in conjunction with an N-body simulation of structure formation, to predict the power spectrum of intensity fluctuations in the infrared background. We compute the emission from galaxies at far-infrared, millimetre and radio wavelengths. Our method gives accurate predictions for the clustering of galaxies both for the one halo and two halo terms. We illustrate our new framework using a previously published model which reproduces the number counts and redshift distribution of galaxies selected by their emission at $850\,μ$m. Without adjusting any of the model parameters, the predictions show encouraging agreement at high frequencies and on small angular scales with recent estimates of the extragalactic fluctuations in the background made from early data analysed by the Planck Collaboration. There are, however, substantial discrepancies between the model predictions and observations on large angular scales and at low frequencies, which illustrates the usefulness of the intensity fluctuations as a constraint on galaxy formation models.

The extracellular mannoprotein Cig1 functions in iron acquisition from heme in the fungal pathogen Cryptococcus neoformans.
Creators: name: Cadieux, Brigitte
Publisher: name: University of British Columbia
Year: 2013

description: Cryptococcus neoformans is an encapsulated fungal pathogen that causes cryptococcosis, a life-threatening disease which affects an estimated 1 million people worldwide annually. Iron acquisition is an important but poorly understood aspect of the pathogenesis of C. neoformans. In particular, no heme uptake system has thus far been characterized in this fungus, although it has been shown to utilize heme as an iron source. A previous study identified the transcript for the extracellular mannoprotein CIG1 as the most abundant message in iron-starved cells with marked down-regulation by iron repletion, thus suggesting a possible iron-related role for Cig1. In the current study, it was found that deletion of CIG1 resulted in an extended lag phase in low iron medium with heme added as the sole iron source. Additionally, the cig1Δ mutant was more resistant to toxic heme analogs than the wild-type or complemented strains implying a role for Cig1 in heme uptake. Western blot analysis and immunofluorescence microscopy identified Cig1 at the cell surface and in association with extracellular vesicles. A heme pull-down experiment, absorbance spectroscopy and isothermal calorimetry also demonstrated that Cig1 is a potential heme-binding protein. Importantly, deletion of CIG1 led to attenuated virulence in a mouse infection model in absence of the high-affinity iron uptake system. More detailed studies on Cig1 revealed that the length of the lag phase of a cig1Δ mutant in low iron medium supplemented with heme was dependent on the inoculum size in support of a cell density-dependent heme acquisition system. Similarly, growth at acidic pH rescued the heme defect of a cig1Δ mutant indicating the presence of a Cig1-independent pathway at low pH. The transcription factor Rim101 may function in this pathway. Finally, expression of a Cig1 truncated polypeptide established a role for Cig1 in secretion and cell wall integrity. In this context, a strain overexpressing CIG1 produced an enlarged capsule and secreted more extracellular vesicles than the wild-type strain. Overall, the data presented in this thesis have contributed to a better understanding of heme uptake and secretion in C. neoformans and the results may facilitate the development of new strategies to treat cryptococcosis.

description: We compute various processes involving neutrinos in the initial and/or final state and we assume that neutrinos have energy momentum relation with a general power law $E^2 =p^2+ ξ_n p^n$ correction due to Lorentz invariance violation. We find that for $n>2$ the bounds on $ξ_n$ from direct time of flight measurement are much more stringent than from constraining the neutrino Cerenkov decay process.

Multiple stellar systems and the pathway to gravitational wave sources
Creators: name: Toonen, Silvia
Publisher: name: Zenodo
Year: 2023

description: Stars are the fundamental building blocks of galaxies and stellar clusters, and are often part of small stellar systems in which the stars can interact with each other. The abundance of binary systems is well known, however triple configurations and higher-order multiples are common as well. In fact, observations indicate that for solar-mass star systems one in four binaries has an  additional companion, whereas massive stars are even predominantly part of multiple systems and rarely single stars or part of binaries. For this reason triple evolution is essential for the evolution of stars systems, and  all the exotic phenomena they can give rise to, such as gravitational wave events. But while triple star systems are common, our understanding of their evolution has lagged behind compared to single and binary stars. In this talk I will review our current understanding of the evolution of massive stellar triples. I will discuss how triple stars can evolve differently from binary stars, and show their potential as gravitational wave progenitors.

description: We analyze the optomechanics-like properties of a Bose-Einstein condensate (BEC) trapped inside an optical resonator and driven by both a classical and a quantized light field. We find that this system exhibits a nature of role reversal between the matter-wave field and the quantized light field. As a result, the matter wave field now plays the role of the quantized light field, and the quantized light field behaves like a movable mirror, in contrast to the familiar situation in BEC-based cavity optomechanics [Brennecke et al., Science 322, 235 (2008); Murch et al., Nat. Phys. 4, 561 (2008)]. We demonstrate that this system can lead to the creation of a variety of nonclassical matter-wave fields, in particular cat states, and discuss several possible protocols to measure their Wigner function.
Per una lettura laica della teologia medievale

Publisher: name: Università degli Studi di Milano

description: È possibile operare una forma di epoché sui concetti di carattere teologico? Ed è possibile riflettere sulla loro importanza, prescindendo dalla loro portata religiosa? I concetti teologici riescono a dirci qualcosa, se si trascura il loro riferimento essenziale alla nostra relazione con un essere divino? La risposta a queste domande consente di comprendere che cosa significhi essere un studioso laico della filosofia medievale, mentre è impossibile discutere tale problema senza prendere in considerazione anche la teologia medievale. Tutto ciò dunque riguarda non solo la natura della teologia, ma anche l’idea stessa di laicità. Dunque una storiografia del pensiero medievale pienamente consapevole di se stessa deve studiare il discorso teologico e affrontare in profondità la portata teorica di questo problema. Si può concludere che per una lettura laica della teologia medievale è paradossalmente essenziale cogliere proprio il senso intimo del pensiero religioso e le forme storicamente determinate della sua effettiva concettualizzazione.

 Is some form of epoché possible on theological concepts? In which way? Is it possible consider their importance leaving their religious scope aside? Can the theological concepts tell us something unless we consider their essential reference to our relationship with a divine being? The answer to these questions let us to understand what means to be a secular (laico) scholar of medieval philosophy. It's impossible conversely to discuss this problem without dealing with medieval theology. And this concerns not only the nature of theology, but also and deeply the same idea of secularism (laicità). Therefore a fully aware historiography of medieval thought has to understand the theological speech and to encounter the depth of this theoretical question. So we can conclude that for a secular reading of the medieval theology is paradoxically essential to catch the intimate sense of religious thought and the historically defined forms of its actual conceptualizations.

description: Recently reported tentative evidence for a gamma-ray line in the Fermi-LAT data is of great potential interest for identifying the nature of dark matter. We compare the implications for decaying and annihilating dark matter taking the constraints from continuum gamma-rays, antiproton flux and morphology of the excess into account. We find that higgsino and wino dark matter are excluded, also for nonthermal production. Generically, the continuum gamma-ray flux severely constrains annihilating dark matter. Consistency of decaying dark matter with the spatial distribution of the Fermi-LAT excess would require an enhancement of the dark matter density near the Galactic center.

description: In a previous article [JHEP 1111 (2011) 072; arXiv:1108.4965] we have developed a Lorentzian version of the Quantum Regge Calculus in which the significant differences between simplices in Lorentzian signature and Euclidean signature are crucial. In this article we extend a central result used in the previous article, regarding the realizability of Lorentzian triangles, to arbitrary dimension. This technical step will be crucial for developing the Lorentzian model in the case of most physical interest: 3+1 dimensions. We first state (and derive in an appendix) the realizability conditions on the edge-lengths of a Lorentzian n-simplex in total dimension n=d+1, where d is the number of space-like dimensions. We then show that in any dimension there is a certain type of simplex which has all of its time-like edge lengths completely unconstrained by any sort of triangle inequality. This result is the d+1 dimensional analogue of the 1+1 dimensional case of the Lorentzian triangle.

Urban spaces of deviance and rebellion : youth, squatted houses and the heroin scene in West Germany and Switzerland in the 1970s and 1980s
Creators: name: Friedrichs, Jan-Henrik
Publisher: name: University of British Columbia
Year: 2013

description: Between the late 1970s and early 1980s, Western European societies experienced a deep crisis, involving economic turmoil and youth protest, that became most perceptible in an alleged crisis of the city. This dissertation argues that as a reaction to this crisis a spatialization of the social took place that established urban space as a prime object of governmental policies. It argues further that the transformation of social problems into questions of spatial order was mirrored in a growing reference by non-conforming youth to space as a site of liberation. Both developments supported and influenced each other and were based on the conception of certain socio-geographical spaces as counter-sites that differed entirely from all other spaces. Spaces of non-conforming youth are therefore at the heart of this dissertation. Meeting places of the heroin scene and squatted houses in Zurich and various West German cities, most notably West Berlin, serve as examples of such spaces and their significance for European societies in the early 1980s. This study employs a double perspective. It traces the spaces of youth deviance as an object of governmental technologies and seeks to deconstruct the underlying assumptions about normalcy, deviance, youth, and urban space. At the same time, it explores the practices and imaginations of those youth who were seeking to evade or rebel against the hegemonic order through squatting of, and sojourning at, specific urban spaces. To grasp the perspective of both governmental institutions and non-conforming youth, a combined analysis of their discursive and spatial practices is employed. Making use of Foucault's concept of heterotopia, or “other spaces”, the possibilities and limitations in regulating and creating social change through urban spaces of deviance and rebellion comes into focus. This dissertation therefore contributes to a social and cultural historiography of the 1980s as well as furthers our understanding of the mutually constructed nature of space, youth, normalcy, and deviance.
“The Mysterious Other”: Carter’s Japanese Reflections
Creators: name: Pasolini, Anna
Publisher: name: Università degli  Studi di Milano
Year: 2012

description: Angela Carter’s Japanese experience (1970-1971) profoundly affected the writer, influencing all her following works. The collections Nothing Sacred (1982) and Fireworks: Nine Profane Pieces (1974), gathering respectively journalistic writings and short stories, show how the Japanese years prompted to strengthen her criticism towards the Western patriarchal tradition and to codify a new paradigm for the representation and enactment of performative female identity(-ies).
As it has been argued, Carter’s perspective is that of a Western tourist, looking down on Japanese culture and society with an imperial gaze. However, this very point of view proves to be both problematic and productive, for her being a Western foreigner (the imperial Eye), combines with her being a woman, a subject who speaks from an unprivileged position, the subordinated Other in her homeland. Moreover, as Carter declared, she did not know nor was able to learn the Japanese language, thus being forced –and willing- to observe reality with sharpened senses in order to name everything anew, starting from her self-perception of what it means to be a woman and to act as one.   Thus, the author fills in Japanese empty signs with brand new meanings and begins to build up a new system of signification from the ambivalent perspective of a foreign woman, whose otherwise underprivileged position is empowered by the fact of being British. Her impressions of the Japanese world and her reasonings about gendered identities are then conveyed though the powerful, omnipresent image of the mirror. In Carter’s wor(-ds)k mirrors and reflections are at the same time both the means which make disruptive and original models and performances possible and effective ways to represent them, since it is through the reflection/projection of Japanese culture into the Western one and through the mirroring of the female subject in the other’s eyes, that female subjectivity is endowed with a new –subversive- potential.

description: In this work we develop a systematic geometric approach to study fully nonlinear elliptic equations with singular absorption terms as well as their related free boundary problems. The magnitude of the singularity is measured by a negative parameter $(γ-1)$, for $0 < γ< 1$, which reflects on lack of smoothness for an existing solution along the singular interface between its positive and zero phases. We establish existence as well sharp regularity properties of solutions. We further prove that minimal solutions are non-degenerate and obtain fine geometric-measure properties of the free boundary $\mathfrak{F} = \partial \{u > 0 \}$. In particular we show sharp Hausdorff estimates which imply local finiteness of the perimeter of the region $\{u > 0 \}$ and $\mathcal{H}^{n-1}$ a.e. weak differentiability property of $\mathfrak{F}$.

description: The presence of light sterile neutrinos would strongly modify the energy spectrum of the Tritium β-electrons. We perform an analysis of the KATRIN experiment's sensitivity by scanning almost all the allowed region of neutrino mass-squared difference and mixing angles of the 3+1 scenario. We consider the effect of the unknown absolute mass scale of active neutrinos on the sensitivity of KATRIN to the sterile neutrino mass. We show that after 3 years of data-taking, the KATRIN experiment can be sensitive to mixing angles as small as sin^2 (2θ_s) ~ 10^-2. Particularly we show that for small mixing angles, sin^2 (2θ_s) < 0.1, the KATRIN experiment can gives the strongest limit on active-sterile mass-squared difference.

A necessary condition appears to the balanced property, or a matching between the numbers of incoming and outgoing edges; we show that a graph without an orientation, locally finite and at most countably infinite, can made balanced oriented \emph{iff} the degree of each vertex is even. On such graphs we construct families of momentum operators; we analyze their spectra and associated unitary groups. We also show that the unique continuation principle does not hold here.

description: This paper means to show how British Colonialism in India was made possible, and then sustained and strengthened, as much by cultural technologies of rule as it was by the more obvious and brutal modes of conquest. In fact colonialism was itself a cultural project of control. Colonial knowledge both enabled conquest and was produced by it. Cultural forms in Indian society were reconstructed and transformed by this knowledge. In the conceptual scheme which the British created to understand and to act in India they reduced vastly complex codes and their associated meanings to a few metonyms. An example of  colonial way of organizing and representing Indian social identity is offered by the British construction of Indian Gypsies. This communication is meant to explain first the logic of such an identification and then the new authority and vitality currently attained by this product of Orientalism in Romani political organizations and cultural associations.

Standard Model with Partial Gauge Invariance

description: We argue that an exact gauge invariance may disable some generic features of the Standard Model which could otherwise manifest themselves at high energies. One of them might be related to the spontaneous Lorentz invariance violation (SLIV) which could provide an alternative dynamical approach to QED and Yang-Mills theories with photon and non-Abelian gauge fields appearing as massless Nambu-Goldstone bosons. To see some key features of the new physics expected we propose partial rather than exact gauge invariance in an extended SM framework. This principle applied, in some minimal form, to the weak hypercharge gauge field B_{mu} and its interactions leads to SLIV with B field components appearing as the massless Nambu-Goldstone modes, and provides a number of distinctive Lorentz beaking effects. Being naturally suppressed at low energies they may become detectable in high energy physics and astrophysics. Some of the most interesting SLIV processes are considered in significant detail.

description: Addressing a quest by Gupta et al. (in: Proceedings of the 41st international colloquium on automata, languages, and programming (ICALP 2014), vol 8572 of LNCS. Springer, pp 563–575, 2014), we provide a first, comprehensive study of finding a short s–t path in the multistage graph model, referred to as the MULTISTAGE s–t PATH problem. Herein, given a sequence of graphs over the same vertex set but changing edge sets, the task is to find short s–t paths in each graph (“snapshot”) such that in the found path sequence the consecutive s–t paths are “similar”. We measure similarity by the size of the symmetric difference of either the vertex set (vertex-similarity) or the edge set (edge-similarity) of any two consecutive paths. We prove that these two variants of MULTISTAGE s–t PATH are already NP-hard for an input sequence of only two snapshots and maximum vertex degree four. Motivated by this fact and natural applications of this scenario e.g. in traffic route planning, we perform a parameterized complexity analysis. Among other results, for both variants, vertex- and edge-similarity, we prove parameterized hardness (W[1]-hardness) regarding the parameter path length (solution size). As a further conceptual investigation, we then modify the multistage model by asking for dissimilar consecutive paths. As one of the main technical results (employing so-called representative sets known from non-temporal settings), we prove that dissimilarity allows for fixed-parameter tractability for the parameter solution size, contrasting with our W[1]-hardness proof of the corresponding similarity case. We also provide partially positive results concerning efficient and effective data reduction (kernelization).

Subjects: Muslim Women; Islamophobia; Neo Orientalism

description: In post 9/11 one of the main focuses of the debate over Islam concerns the situation of women in Muslim countries. The rhetoric of Muslim women’s liberation has produced a huge wave of Islamophobia and has generated (Neo) Orientalist representations of the “oppressed” Muslim women in need of imperialist interventions. The promoters of this campaign are both Western “feminists” and “dissident” Muslim women who, by pretending to fight for  human rights, have produced a sensationalist Neo-orientalist literature based on the assumption of the existence of a unique, eternal and denigrated “Muslim woman”.
This article explores some Neo-orientalist issues fabricated around the myth of “the Muslim woman” by Western women observers also with the complicity of female “native informants”.

Correlators between n-point functions measured in one patch of the sky and k-point functions measured in another patch depend upon the (n+k)-point functions over the entire sky. The inhomogeneity of non-Gaussian parameters may be a feasible way to detect or constrain higher-order correlators in local models of non-Gaussianity, as well as to distinguish between single and multiple-source scenarios for generating the primordial density perturbation, and more generally to probe the details of inflationary physics.

description: We consider the problem of detecting the true quantum state among $r$ possible ones, based of measurements performed on $n$ copies of a finite-dimensional quantum system. A special case is the problem of discriminating between $r$ probability measures on a finite sample space, using $n$ i.i.d. observations. In this classical setting, it is known that the averaged error probability decreases exponentially with exponent given by the worst case binary Chernoff bound between any possible pair of the $r$ probability measures. Define analogously the multiple quantum Chernoff bound, considering all possible pairs of states. Recently, it has been shown that this asymptotic error bound is attainable in the case of $r$ pure states, and that it is unimprovable in general. Here we extend the attainability result to a larger class of $r$-tuples of states which are possibly mixed, but pairwise linearly independent. We also construct a quantum detector which universally attains the multiple quantum Chernoff bound up to a factor 1/3.

L’Europa non si è vista solo come l’altro rispetto all’Oriente, ma anche come l’altro rispetto al suo Meridione: il presente moderno del Nord di contro al passato antico del Sud. Nella seconda metà del Settecento, il secolo della nascita dell’orientalismo come sapere organico all’impresa coloniale dell’Occidente, vennero gettati anche i semi della pianta del meridionismo, sapere organico all’impresa della costruzione della moderna identità europea. I romantici inglesi coltivarono questa pianta.

description: Analysis of resistance groups active in the War on Terror provides case-studies for an examination of Occidentalism. Al-Qaida constructs a West both homogeneously and pejoratively in order to represent the self as a single Islamic nation under attack from a barbarian other. Concerned with propagating their narrative, al-Qaida considers the media battle to be at the forefront of their efforts. Yet global dissemination of their message is double-edged: positively, it can inspire disparate would-be jihadists; negatively, it opens up the discourse to examination in West. The discourse is studied, dissected and ultimately incorporated into the Western knowledge structure.

description: For the Bell scenario with two parties and two binary observables per party, it is known that the no-signaling polytope is the polyhedral dual (polar) of the Bell polytope. Computational evidence suggests that this duality also holds for three parties. Using ideas of Werner, Wolf, Żukowski and Brukner, we prove this for any number of parties by describing a simple linear bijection mapping (tight) Bell inequalities to (extremal) no-signaling boxes and vice versa. Furthermore, a symmetry-based technique for extending Bell inequalities (resp. no-signaling boxes) with two binary observables from n parties to n+1 parties is described; the Mermin-Klyshko family of Bell inequalities arises in this way, as well as 11 of the 46 classes of tight Bell inequalities for 3 parties. Finally, we ask whether the set of quantum correlations is self-dual with respect to our transformation. We find this not to be the case in general, although it holds for 2 parties on the level of correlations. This self-duality implies Tsirelson's bound for the CHSH inequality.

Scrivere al tornio, modellare il testo:  Edmund de Waal tra istallazione e memoir
Creators: name: Cuojati, Francesca
Publisher: name: Università degli  Studi di Milano
Year: 2012

description: The Hare with Amber Eyes (2010) by Edmund de Waal is a memoir written by “a very textual potter”. Thanks to the inheritance of a collection of tiny Japanese carvings, de Waal leaves on a journey to Paris, Vienna, Odessa, back to his Jewish roots in nineteenth century aesthtecisism and in the tragedy of the Shoah. Drawing parallels between his writing, collecting and the plastic arts of pottery, the author explores the affinities between artefact and word, installation and proposition, collection and archive.
 The Hare can be read in the context of what R. Wendorf has defined a “literature of collecting,” including critical theory as well as narratives dealing with its practices. Rich in intertextual excursions, de Waal’s autobiographical writing develops a fruitful conversation with W. Benjamin’s 1931 paradigmatic text “Unpacking my Library”. Also P. Levi’s La chiave a stella riverberates in the writer’s awareness of the importance of precision in practices like creating an installation and writing about the past, involving both aesthetic and moral responsabilities.
 De Waal’s stance about the transitivity between art and writing finally emerges from the very rhetorics of his work which abounds in circular structures like the red alluminium ring which sustains his installation at the V&A Ceramics Galleries and the figure of the chiasmus which organizes his prose writing, linking him yet again to his Jewish cultural origins.

description: We reinterpret and generalize conjectures of Lam and Williams as statements about the stationary distribution of a multispecies exclusion process on the ring. The central objects in our study are the multiline queues of Ferrari and Martin. We make some progress on some of the conjectures in different directions. First, we prove their conjectures in two special cases by generalizing the rates of the Ferrari-Martin transitions. Secondly, we define a new process on multiline queues, which have a certain minimality property. This gives another proof for one of the special cases; namely arbitrary jump rates for three species.

FAST(ER) DATA GENERATION FOR OFFLINE RL AND FPS ENVIRONMENTS FOR DECISION TRANSFORMERS
Creators: name: Trovinger, Mark R
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: classificationCode: 461105
subject: Reinforcement learning

description: Reinforcement learning algorithms have traditionally been implemented with the goalof maximizing a reward signal. By contrast, Decision Transformer (DT) uses a transformermodel to predict the next action in a sequence. The transformer model is trained on datasetsconsisting of state, action, return trajectories. The original DT paper examined a smallnumber of environments, five from the Atari domain, and three from continuous control,and one that examined credit assignment. While this gives an idea of what the decisiontransformer can do, the variety of environments in the Atari domain are limited. In thiswork, we propose an extension of the environments that decision transformer can be trainedon by adding support for the VizDoom environment. We also developed a faster method foroffline RL dataset generation, using Sample Factory, a library focused on high throughput,to generate a dataset comparable in quality to existing methods using significantly less time.
Oltre l’Oriente e l’Occidente. l’orientalismo di Tawfīq al-Ḥakīm
Creators: name: Pugliesi, Girolamo
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Orientalismo; Oriente; Occidente

description: Terms like "East" and "West" are metaphors rather than categories in a technical sense. In particular, the metaphor of "East" has played a decisive role in the development of "orientalistic disciplines" and has also influenced the so-called Eastern populations. The analysis of the literary production of one of the greatest exponents of Egyptian culture in the Twentieth Century - Tawfiq al-Hakim (1898-1987) - will allows us to describe how he modified the vision of the East which was typical of the European Orientalism, beyond the alternative between East and West.

description: The congruence subgroup property is established for the modular representations associated to any modular tensor category. This result is used to prove that the kernel of the representation of the modular group on the conformal blocks of any rational, C_2-cofinite vertex operator algebra is a congruence subgroup. In particular, the q-character of each irreducible module is a modular function on the same congruence subgroup. The Galois symmetry of the modular representations is obtained and the order of the anomaly for those modular categories satisfying some integrality conditions is determined.

description: I discuss a correspondence between string theory and the black hole membrane paradigm in the context of the D1-D5-P system. By using the Kubo formula, I calculate transport coefficients of the effective string model induced by two kinds of minimal scalars. Then, I show that these transport coefficients exactly agree with the corresponding membrane transport coefficients of a five-dimensional near-extremal black hole with three charges.

description: In an attempt to remove the systematic errors which have plagued the calibration of the HII region abundance sequence, we have theoretically modeled the extragalactic HII region sequence. We then used the theoretical spectra so generated in a double blind experiment to recover the chemical abundances using both the classical electron temperature + ionization correction factor technique, and the technique which depends on the use of strong emission lines (SELs) in the nebular spectrum to estimate the abundance of oxygen. We find a number of systematic trends, and we provide correction formulae which should remove systematic errors in the electron temperature + ionization correction factor technique. We also provide a critical evaluation of the various semi-empirical SEL techniques. Finally, we offer a scheme which should help to eliminate systematic errors in the SEL-derived chemical abundance scale for extragalactic HII regions.

Orientalisms within: Encountering Indian Subaltern Experiences
Creators: name: Thomas, Tom
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: orientalisms; India; religion; caste; gender

description: The paper looks at the Indian nation, which grows increasingly intolerant of heterogenity. The death of M.F. Husain, the Rushdie controversy and the censoring of A.K. Ramanujan’s essay attest this fact. The subaltern experience of two significant land struggles in the state of Kerala—the Muthanga agitation spearheaded by a tribal woman C.K. Janu and the Chengara land struggle under a dalit Laha Gopalan—testify to the presence of “orientalisms” within. Schisms within the subaltern movement, opposition from Marxist outfits and the geographical spaces of land “occupied”; autobiographies of Janu, Mukhtar Mai and Nalini Jameela, incidents of “honour killing,” slut walk, breast tax and “love jihad” are interrogated . The complexities of orientalisms, which work along the identities of religion, caste and gender are dealt with.
