Was ist das Andere des Prekären? Überlegungen zur Darstellung prekärer Arbeit heute

Year: 2012

description: Judith Siegmund What is the Other of Precarity? Considerations on the Representation of Precarious Work Today This paper inquires into the imagined Other of precarity from the perspective of cultural philosophy. Which norms are implicitly applied when the contemporary subject is termed “precarious” or when there is mention of “precarious subjectivity.” Exploring social science and social psychology theories as regards the premises on which their respective critiques of precarity are based, this contribution shows how a traditional negative dialectics of economic security and freedom is virulent notwithstanding intentions to the contrary. The central claim of this paper, however, is that a positive dialectics needs to be developed in response to these conditions.

Anti-Gone

Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2012

description: Anti-Gone From a psychoanalytic perspective, the article explores the relation between precariousness and mourning – or rather, the inability to mourn, which Sigmund Freud described as melancholia. Referring to Judith Butler and Melanie Klein, it focuses on the question of how the unlamentable loss – the lost paradise – is re-performed in science fiction narratives. Our relationship with what is lost, the text argues, is based on half-knowledge, which projects the interminable past psychotically into the future, thus trying to remain connected to what is gone.

Alfons Mucha's The Lord's Prayer: Fin de Siècle Illustrations of Gender and Spirituality
Creators: name: Hale, Meredith
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Alfons Mucha’s illustrated and annotated book The Lord’s Prayer (1899) presents a mystical and feminine realization of the “Our Father” that reflects the variety of spiritual traditions present at the fin de siècle while departing from conventional, often negative, depictions of women. Mucha, who practiced both Catholicism and Freemasonry, combined the beliefs of faiths that were frequently at odds with one another in his version of the prayer. The Catholic clergy criticized his French commentary for using feminine mystical titles for God. In response, Mucha created a second Czech version that reaffirmed masculine Christian conventions. While Mucha transformed his commentary, the images that depicted this radical text went unaltered. My examination of these illustrations reveals the close relationship between the spiritual and the feminine that Mucha’s imagery asserts. The absence of standard symbols, like Christ and his crucifixion, and their replacement with feminine figures provided women with increased spiritual visibility.

Against the background of current developments in European theatre, this contribution discusses the work of René Pollesch and of Japanese writer and director Toshiki Okada. Both perform precarity in the sense of economic uncertainty, and both stage as precarious characters connotated in particular as female.

Inszenierungen des Prekären. Verletzbarkeit und Geschlechtsidentität in Alain Platels Gardenia
Creators: name: Dreysse, Miriam
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2012

description: Stagings of Precarity. Vulnerability and Gender Identity in Alain Platel’s Gardenia Departing from Judith Butler’s notion of the precarious as the general vulnerability of the human subject, the text questions the possibilities of contemporary performing arts to stage the precariousness of the other and thus insist on the singularity of each one of us. The dance performance Gardenia by Alain Platel and the Ballet C de la B from 2008 is analyzed as an example of the staging of vulnerability and otherness. The performers of Gardenia are a group of elderly transsexuals and transvestites, thus representing the precarious life relating both to their age (especially as dancers) and their gender identity.

The Effect of Blade Row Interaction on Rotor Film Cooling

description: In gas turbines, film cooling is required to protect metal parts from hot combustion gases. Reduction in coolant mass flow increases cycle efficiency, and hence reduces greenhouse gas emissions. However, the lifespan of a cooled component is sensitive to the metal temperature within the part. A designer requires predictions of cooling performance to make this compromise, yet present design methods are subject to uncertainty and are not viable without empirical input. Flow through a turbine is inherently unsteady due to relative motion of stators and rotors, termed blade row interaction. Blade row interaction is not captured in flat-plate and cascade testing, or present design methods, contributing to uncertainty in predicted cooling performance. The aims of this thesis are to establish the mechanisms by which blade row interaction affects rotor film cooling, and quantify their influence on cooling performance in a representative case. A new experimental rig is developed to facilitate aerodynamic and heat transfer measurements of cooling holes subject to unsteady main-stream boundary conditions. The effect of unsteadiness is set by non-linearity in the hole response. Unsteadiness reduces film effectiveness by up to 31% with cylindrical holes at a low momentum flux ratio, because the response to perturbations is non-linear. Cylindrical holes at a high momentum flux ratio, and fan-shaped holes, are robust to unsteadiness because they respond linearly. Non-film-resolved computations are used to identify the blade row interaction mechanisms generating unsteady main-stream boundary conditions in a turbine rotor. A quasi-steady model is used to predict instantaneous excursions in cooling hole momentum flux ratio. Fluctuations of at least ±30% are present for all hole locations, due to both upstream vane wake and potential field interaction. A hybrid URANS–LES computational approach is implemented, validated against experimental data, and applied to a turbine stage cascade model. Compared to steady conditions, blade row interaction reduces rotor film effectiveness: by up to 18% on the pressure side, due to migration of vane coolant across the passage; and by up to 30% on the suction side, due to wake interactions increasing the film mixing rate.

description: Modern latency-critical online services often rely on composing results from a large number of server components. Hence the tail latency (e.g. the 99th percentile of response time), rather than the average, of these components determines the overall service performance. When hosted on a cloud environment, the components of a service typically co-locate with short batch jobs to increase machine utilizations, and share and contend resources such as caches and I/O bandwidths with them. The highly dynamic nature of batch jobs in terms of their workload types and input sizes causes continuously changing performance interference to individual components, hence leading to their latency variability and high tail latency. However, existing techniques either ignore such fine-grained component latency variability when managing service performance, or rely on executing redundant requests to reduce the tail latency, which adversely deteriorate the service performance when load gets heavier. In this paper, we propose PCS, a predictive and component-level scheduling framework to reduce tail latency for large-scale, parallel online services. It uses an analytical performance model to simultaneously predict the component latency and the overall service performance on different nodes. Based on the predicted performance, the scheduler identifies straggling components and conducts near-optimal component-node allocations to adapt to the changing performance interferences from batch jobs. We demonstrate that, using realistic workloads, the proposed scheduler reduces the component tail latency by an average of 67.05\% and the average overall service latency by 64.16\% compared with the state-of-the-art techniques on reducing tail latency.

description: The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes that giant protoplanets can be formed directly from collapsing fragments of vast spiral arms induced by gravitational instability -- if the disk is gravitationally unstable. For this to be possible, the disk must be massive compared to the central star: a disk-to-star mass ratio of 1/10 is widely held as the rough threshold for triggering gravitational instability, inciting significant non-Keplerian dynamics and generating prominent spiral arms. While estimating disk masses has historically been challenging, the motion of the gas can reveal the presence of gravitational instability through its effect on the disk velocity structure. Here we present kinematic evidence of gravitational instability in the disk around AB Aurigae, using deep observations of 13CO and C18O line emission with the Atacama Large Millimeter/submillimeter Array (ALMA). The observed kinematic signals strongly resemble predictions from simulations and analytic modelling. From quantitative comparisons, we infer a disk mass of up to 1/3 the stellar mass enclosed within 1" to 5" on the sky.

description: A well-established phenomenon in general relativity is the dragging of inertial frames by a spinning object. In particular, due to the dragging of inertial frames by a ring orbiting a central black hole, the angular-velocity of the black-hole horizon in the composed black-hole-ring system is no longer related to the black-hole angular-momentum by the simple Kerr-like (vacuum) relation $Ω^{\text{Kerr}}_{\text{H}}(J_{\text{H}})=J_{\text{H}}/2M^2R_{\text{H}}$. Will has performed a perturbative treatment of the composed black-hole-ring system in the regime of slowly rotating black holes and found the explicit relation $Ω^{\text{BH-ring}}_{\text{H}}(J_{\text{H}}=0,J_{\text{R}},R)=2J_{\text{R}}/R^3$ for the angular-velocity of a central black hole with zero angular-momentum. Analyzing a sequence of black-hole-ring configurations with adiabatically varying (decreasing) circumferential radii, we show that the expression found by Will implies a smooth transition of the central black-hole angular-velocity from its asymptotic near-horizon value $Ω^{\text{BH-ring}}_{\text{H}}(J_{\text{H}}=0,J_{\text{R}},R\to R^{+}_{\text{H}})$ to its final Kerr (vacuum) value $Ω^{\text{Kerr}}_{\text{H}}(J^{\text{new}}_{\text{H}})$. We use this important observation in order to generalize the result of Will to the regime of black-hole-ring configurations in which the central black holes possess non-zero angular momenta. Remarkably, we find the simple universal relation $ΔΩ_{\text{H}}\equivΩ^{\text{BH-ring}}_{\text{H}}(J_{\text{H}},J_{\text{R}},R\to R^{+}_{\text{H}})-Ω^{\text{Kerr}}_{\text{H}}(J_{\text{H}})={J_{\text{R}}/{4M^3}}$ for the asymptotic deviation of the black-hole angular-velocity in the composed black-hole-ring system from the corresponding angular-velocity of the unperturbed (vacuum) Kerr black hole with the same angular-momentum.

New insights into migration of the Cretaceous Sierran arc using highprecision U-Pb geochronology
Creators: name: Beck, Courtney
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: A compilation of 254 U-Pb zircon and K-Ar and Ar-Ar biotite ages for the central Sierra Nevada batholith, CA, shows no record of monotonic west-to-east migration of magmatism during the Cretaceous. Rather, spatial age variation in the central Sierra Nevada batholith is dominated by 1) a stepwise shift of the locus of magmatism 2) a west-to-east migration to the end of magmatism and 3) patterns within intrusive suites that reflect local crustal deformation. The step in magmatism was contemporaneous with the beginning of the Sierra Crest magmatic event and beginning of deformation along ductile shear zones in the eastern Sierra. At ~102 Ma, a laterally extensive shear zone formed along the eastern margin of the Cretaceous batholith and was localized and dissected by Sierra Crest plutons. Central Sierran biotite ages cluster between ~78 and 90 Ma and may reflect batholith-wide exhumation or cooling related to waning of local magmatism.
Nonstandard homology theory for uniform spaces

description: We introduce a new homology theory of uniform spaces, provisionally called $μ$-homology theory. Our homology theory is based on hyperfinite chains of microsimplices. This idea is due to McCord. We prove that $μ$-homology theory satisfies the Eilenberg-Steenrod axioms. The characterization of chain-connectedness in terms of $μ$-homology is provided. We also introduce the notion of S-homotopy, which is weaker than uniform homotopy. We prove that $μ$-homology theory satisfies the S-homotopy axiom, and that every uniform space can be S-deformation retracted to a dense subset. It follows that for every uniform space $X$ and any dense subset $A$ of $X$, $X$ and $A$ have the same $μ$-homology. We briefly discuss the difference and similarity between $μ$-homology and McCord homology.

description: In this paper, we study the progressive collapse of 3D framed structures made of reinforced concrete after the sudden loss of a column. The structures are represented by elasto-plastic Euler Bernoulli beams with elongation-rotation failure threshold. We performed simulations using the Discrete Element Method considering inelastic collisions between the structural elements. The results show what collapse initiation and impact-driven propagation mechanisms are activated in structures with different geometric and mechanical features. Namely, we investigate the influence of the cross sectional size and reinforcement $α$ and of the plastic capacity $β$ of the structural elements. We also study the final collapse extent and the fragment size distribution and their relation to $α$, $β$ and to the observed collapse mechanisms. Finally, we compare the damage response of structures with symmetric and asymmetric reinforcement in the beams.
Whole-exome sequencing of de novo genetic variants in a Chinese family with a sporadic case of congenital nonsyndromic hearing loss

description: Background: We examined the genetic variants of a Chinese family with a 22-month-old infant with sporadic non-syndromic sensorineural hearing loss (NSHL). Methods: Whole-exome sequence analysis in the family and variants function assay in cells was performed. The whole-exome sequence data in the family, especially the de novo variants presented in the patient were analyzed and the effect of the disease-causing genetic variants on the protein expression level and cellular localization were examined by cell-based function assay. Results: The infant had no known NSHL-causing variants, except two compound heterozygous variants in connexin26 gene GJB2; one was the c.79G>A, c.341A>G haplotype from the asymptomatic mother which was benign, and the other was a de novo pathogenic c.262G>C (p.A88P). In vitro, GJB2 with c.262G>C was weakly expressed and displayed a punctate distribution in the cytoplasm and cytomembrane, while wild type GJB2 was robustly expressed in the cytomembrane. We deduced that the de novo pathogenic GJB2 c.262G>C exacerbated loss-of-function in the context of leaky variants c.79G>A, c.341A>G in the patient. Interestingly, further analysis of exome sequences revealed that the occurrence of de novo pathogenic variants in the infant was frequent. Among the total ~47,000 variants, 143 were de novo in the patient,; whereas among all 74 variants predicted to be pathogenic/likely pathogenic, 21 were heterozygous and two were homozygous de novo. The frequency occurrence rate of de novo deleterious variants was much higher (31.1%, 23/74) than that in total (0.34%, 143/47,000). It is notablye that most genes with de novo deleterious variants were environment-sensitive, such as GJB2, MNK1, MNK2, MUC4, RAD21 and DNA copy number variations. Conclusions: The full picture of genetic variants in the exome might help us to interpret the NSHL-causing variants. More research is needed into the causes of de novo deleterious variants and gene-environment interactions in congenital NSHL

description: Magnetic properties of single crystalline SmRu$_{2}$Al$_{10}$ have been investigated by electrical resistivity, magnetic susceptibility, and specific heat. We have confirmed the successive magnetic phase transitions at $T_{\text{N}}=12.3$ K and $T_{\text{M}}=5.6$ K. Resonant x-ray diffraction has also been performed to study the magnetic structures. Below $T_{\text{N}}$, the Sm$^{3+}$ moments order in an incommensurate structure with $q_1=(0, 0.759, 0)$. The magnetic moments are oriented along the orthorhombic $b$ axis, which coincides with the magnetization easy axis in the paramagnetic phase. A very weak third harmonic peak is also observed at $q_3=(0, 0.278, 0)$. The transition at $T_{\text{M}}$ is a lock-in transition to the commensurate structure described by $q_1=(0, 0.75, 0)$. A well developed third harmonic peak is observed at $q_3=(0, 0.25, 0)$. From the discussion of the magnetic structure, we propose that the long-range RKKY interaction plays an important role, in addition to the strong nearest neighbor antiferromagnetic interaction.

description: Great physics breakthroughs are rarely included in the introductory physics or astronomy course. General relativity and binary black hole coalescence are no different, and can be included in the introductory course only in a very limited sense. However, we can design activities that directly involve the detection of GW150914, the designation of the Gravitation Wave signal detected on September 14, 2015, thereby engage the students in this exciting discovery directly. The activities naturally do not include the construction of a detector or the detection of gravitational waves. Instead, we design it to include analysis of the data from GW150914, which includes some interesting analysis activities for students of the introductory course. The same activities can be assigned either as a laboratory exercise or as a computational project for the same population of students. The analysis tools used here are simple and available to the intended student population. It does not include the sophisticated analysis tools, which was used by LIGO to carefully analyze the detected signal. However, these simple tools are sufficient to allow the student to get important results.

description: KERSTIN PINTHER / KERSTIN SCHANKWEILER Entangled Threads: Textile References in the Contemporary Arts of Africa and the Diaspora Unlike the European context, where textiles were rather marginalized within the hierarchy of arts, the production of textiles in many African societies is a specialized and highly appreciated métier. Textiles not only play a crucial role in the negotiation of identities and memories, but their fluidity and genuine adaptability seem to be especially attractive for processes of cultural translation as well as for the contemporary arts. The diverse textile traditions of the African continent are thus important resources and aesthetic references for artists. In this paper we focus on the works of four artists who refer to African textile traditions: Abdoulaye Konaté (“From charm to abstraction”), El Anatsui (“Textile aesthetics in other media”), Ghada Amer (“Embroidery as translation”) and Senzeni Marasela (“Stitching as remembrance and search for new identities”). Their individual artistic approaches to textiles do not only differ with regard to techniques (weaving, stitching et al); they also negotiate different concepts of masculinity and femininity, already inherent in the textile traditions.

Inherited strike-slip faults as an origin for basement-cored uplifts: example of the Kungey and Zailiskey Ranges, northern Tian Shan
Creators: name: Selander, Jacob
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Reactivation of strike-slip faults and formation of new faults in the surrounding crust may be a common origin for high-angle reverse faults characteristic of basement-cored uplifts. This relationship is explored here by examining the growth of the Kungey and Zailiskey Ranges, the northernmost of the Kyrgyz and Kazakh Tian Shan. These ranges are cored by the inherited, ENE-striking Kemin-Chilik fault. Range growth in response to the northward propagation of the Tian Shan has taken place along a network of steeply-dipping faults surrounding the Kemin-Chilik fault. Structual relief is recorded by the deformation of a previously planar unconformity separating Paleozoic basement from Neogene strata. Late Quaternary deformation inferred from deformed river terraces is consistent with the long-term pattern of range growth. Interpretations of cross-sectional fault geometries are consistent with predictions from a mechanical model of slip partitioning developed by an obliquely-slipping, steeply-dipping, reactivated fault at depth.

description: Candidates for correlated topological insulators, originated from the spin-orbit coupling as well as Hubbard type correlation, are expected in the ($111$) bilayer of perovskite-structural transition-metal oxides. Based on the first-principles calculation and tight-binding model, the electronic structure of a LaMnO$_3$ ($111$) bilayer sandwiched in LaScO$_3$ barriers has been investigated. For the ideal undistorted perovskite structure, the Fermi energy of LaMnO$_3$ ($111$) bilayer just stays at the Dirac point, rendering a semi-metal (graphene-like) which is also a half-metal (different from graphene nor previous studied LaNiO$_3$ ($111$) bilayer). The Dirac cone can be opened by the spin-orbit coupling, giving rise to nontrivial topological bands corresponding to the (quantized) anomalous Hall effect. For the realistic orthorhombic distorted lattice, the Dirac point moves with increasing Hubbard repulsion (or equivalent Jahn-Teller distortion). Finally, a Mott gap opens, establishing a phase boundary between the Mott insulator and topological magnetic insulator. Our calculation finds that the gap opened by spin-orbit coupling is much smaller in the orthorhombic distorted lattice ($\sim$$1.7$ meV) than the undistorted one ($\sim$$11$ meV). Therefore, to suppress the lattice distortion can be helpful to enhance the robustness of topological phase in perovskite ($111$) bilayers.

The model used is that which has been termed network analysis. A network is defined as a set of points (in this instance individuals) defined in relation to an initial point of focus (ego) and linked by lines (which indicate that there is a relationship) either directly or indirectly to this initial point of focus. Such a model requires a very detailed and intensive method of investigation which combines lengthy open-ended interviews with participant—observation whenever possible. The Community of Brixton was selected and informants were chosen by a variety of methods. Eighteen women were selected and data on their kinship and friendship relationships were gathered over a period of eighteen months. Most references to West Indian kinship consider mainly the nuclear family, its structure and the problems which exist for these families in this country. Studies refer generally to norms and values to explain behaviour, but it is suggested by this researcher that reference solely to norms and values, especially in an immigrant community where there may be little normative consensus and where values are constantly changing, explains very little about behaviour. Behaviour is better explained by reference to the networks of relationships in which individuals are located, the exchange nature of the relationships, as well as the norms and values of the individuals.

description: LISBETH FREIß Claims on Mexico. Regency after Viennese Fashion As a modernist European discourse, fashion operates as an agent to govern nation, culture, and space. During the nation-state renewal in 19th century Europe, Viennese fashion activated social and spatial borders and policies of appearances, following internal and external colonial intentions. Claims on Mexico analyses Viennese fashion (Wiener Mode) and its countercultures as colonial, national, and social regulatory policy. While the imperial elites in Vienna occupy ethnic and national costume as well as fashion for composing Viennese Fashion to regulate internal colonial and national identification within the Habsburg Monarchy, Maximilian v. Habsburg's assignment to the imperial Mexican crown in 1864 sideswipes Viennese fashion as a colonial regulator. The article discusses the attempt of Maximilian's reign in Mexico to strengthen his regime of Viennese fashions over “Fashion in Mexico”; analyzing references on Mexico in Viennese fashion magazines from 1844 and 1867, as well as Albert Kretschmer's and Carl Rohrbach's history of costumes The Peoples’ Costumes (1864).

description: Topological insulators in the presence of strong Coulomb interaction constitute novel phases of matter. Transitions between these phases can be driven by single-particle or many-body effects. On the basis of {\it ab-initio} calculations, we identify a concrete material, {\it i.e.} Ca$_{2}$PtO$_{4}$, that turns out to be a hole-doped weak topological insulator. Interestingly, the Pt-$d$ orbitals in this material are relevant for the band inversion that gives rise to the topological phase. Therefore, Coulomb interaction should be of importance in Ca$_{2}$PtO$_{4}$. To study the influence of interactions on the weak topological insulating phase, we look at a toy model corresponding to a layer-stacked 3D version of the Bernevig-Hughes-Zhang model with local interactions. For small to intermediate interaction strength, we discover novel interaction-driven topological phase transitions between the weak topological insulator and two Dirac semimetal phases. The latter correspond to gapless topological phases. For strong interactions, the system eventually becomes a Mott insulator.

description: A graph $G$ is hypohamiltonian if $G$ is non-hamiltonian and $G - v$ is hamiltonian for every $v \in V(G)$. In the following, every graph is assumed to be hypohamiltonian. Aldred, Wormald, and McKay gave a list of all graphs of order at most 17. In this article, we present an algorithm to generate all graphs of a given order and apply it to prove that there exist exactly 14 graphs of order 18 and 34 graphs of order 19. We also extend their results in the cubic case. Furthermore, we show that (i) the smallest graph of girth 6 has order 25, (ii) the smallest planar graph has order at least 23, (iii) the smallest cubic planar graph has order at least 54, and (iv) the smallest cubic planar graph of girth 5 with non-trivial automorphism group has order 78.

description: Ba(Zr,Ti)O$_3$ is a lead-free relaxor ferroelectric. Using the first-principles method, the ferroelectric dipole moments for pure BaTiO$_3$ and Ba(Zr,Ti)O$_3$ supercells have been studied. All possible ion configurations of BaZr$_{0.5}$Ti$_{0.5}$O$_3$ and BaZr$_{0.25}$Ti$_{0.75}$O$_3$ are constructed in a $2\times2\times2$ supercell. For the half-substituted case, divergence of ferroelectric properties has been found among these structures, which seriously depends on the arrangement of Ti and Zr ions. Thus our results provide a reasonable explanation to the relaxor behavior of Ba(Zr,Ti)O$_3$. In addition, a model based on the thermal statistics gives the averaged polarization for Ba(Zr,Ti)O$_3$, which depends on the temperature of synthesis. Our result is helpful to understand and tune the relaxor ferroelectricity of lead-free Ba(Zr,Ti)O$_3$.

description: An $r$-fold analogue of the positive semidefinite zero forcing process that is carried out on the $r$-blowup of a graph is introduced and used to define the fractional positive semidefinite forcing number. Properties of the graph blowup when colored with a fractional positive semidefinite forcing set are examined and used to define a three-color forcing game that directly computes the fractional positive semidefinite forcing number of a graph. We develop a fractional parameter based on the standard zero forcing process and it is shown that this parameter is exactly the skew zero forcing number with a three-color approach. This approach and an algorithm are used to characterize graphs whose skew zero forcing number equals zero.

Kleidung als Kunst_ Portrait einer Ikatdesignerin in Ostindonesien

description: WILLEMIJN DE JONG Clothing as Art: The Portrait of a Woman Ikat Designer in Eastearn Indonesia In Eastern Indonesia, hand-woven clothing with ikat designs are highly valued as prestigious artifacts. They are worn at feasts and other public events, exchanged as gifts, and they are sold to locals, tourists and museums. In this article it is argued that richly decorated women’s sarongs created by master weavers represent a unique form of art. This is shown through the analysis of figurative ikat sarongs (lawo gamba) as a special type of textiles, each piece of which is one of a kind. One of the locally well-known master weavers of a main cultural center in Central Flores is portrayed through five of her figurative sarongs created during the period of 1995 to 2011. Referring to Alfred Gell’s social anthropological art theory and the feminist postcolonial approach of the globalization of Asian dress by Sandra Niessen, Ann Marie Leshkowich, and Carla Jones, it is proposed that the figurative ikat clothes in this case study derive their artistic quality from the entanglement of local, national, and transnational processes and social interactions, in which they are imbued with agency through technical skills, aesthetics, and intentionality regarding the ikat designs. By explicitly including certain items of ikat clothing in the global art system, as Sandra Niessen does with certain items of hand-woven clothes from Western Indonesia in the global fashion system, a rethinking of ikat textiles as artifacts in Eastern Indonesian cultural heritage is advocated.

description: When language models (LMs) are trained to forget (or "unlearn'') a skill, how precisely does their behavior change? We study the behavior of transformer LMs in which tasks have been forgotten via fine-tuning on randomized labels. Such LMs learn to generate near-random predictions for individual examples in the "training'' set used for forgetting. Across tasks, however, LMs exhibit extreme variability in whether LM predictions change on examples outside the training set. In some tasks (like entailment classification), forgetting generalizes robustly, and causes models to produce uninformative predictions on new task instances; in other tasks (like physical commonsense reasoning and scientific question answering) forgetting affects only the training examples, and models continue to perform the "forgotten'' task accurately even for examples very similar to those that appeared in the training set. Dataset difficulty is not predictive of whether a behavior can be forgotten; instead, generalization in forgetting is (weakly) predicted by the confidence of LMs' initial task predictions and the variability of LM representations of training data, with low confidence and low variability both associated with greater generalization. Perhaps most surprisingly, random-label forgetting appears to be somewhat insensitive to the contents of the training set: for example, models trained on science questions with random labels continue to answer other science questions accurately, but begin to produce random labels on entailment classification tasks. Finally, we show that even generalizable forgetting is shallow: linear probes trained on LMs' representations can still perform tasks reliably after forgetting. Our results highlight the difficulty and unpredictability of performing targeted skill removal from models via fine-tuning.

Tau-structure for the Double Ramification Hierarchies

description: In this paper we continue the study of the double ramification hierarchy of [Bur15]. After showing that the DR hierarchy satisfies tau-symmetry we define its partition function as the (logarithm of the) tau-function of the string solution and show that it satisfies various properties (string, dilaton and divisor equations plus some important degree constraints). We then formulate a stronger version of the conjecture from [Bur15]: for any semisimple cohomological field theory, the Dubrovin-Zhang and double ramification hierarchies are related by a normal (i.e. preserving the tau-structure [DLYZ14]) Miura transformation which we completely identify in terms of the partition function of the CohFT. In fact, using only the partition functions, the conjecture can be formulated even in the non-semisimple case (where the Dubrovin-Zhang hierarchy is not defined). We then prove this conjecture for various CohFTs (trivial CohFT, Hodge class, Gromov-Witten theory of $\mathbb{CP}^1$, $3$-, $4$- and $5$-spin classes) and in genus $1$ for any semisimple CohFT. Finally we prove that the higher genus part of the DR hierarchy is basically trivial for the Gromov-Witten theory of smooth varieties with non-positive first Chern class and their analogue in Fan-Jarvis-Ruan-Witten quantum singularity theory [FJRW].
