The relationship between performance and curation has shift ed. A new attitude of fluid and pragmatic alliance has evolved as the sense of an essential antagonism between performance and curation recedes and the two fields discover a shared focus on aspects of social engagement and agency. This article considers an Australian socially engaged art project, the Kandos School of Cultural Adaptation (KSCA), which meshes curatorial and artistic practices in its efforts to reimagine and reanimate the future of a small country town. Employing a wide range of strategies, KSCA works closely with the local community to facilitate collective memory, reflection and social and environmental transformation. Deliberately avoiding traditional lines of artistic and institutional tension, KSCA employs an impure and inclusive approach that is emblematic of emerging forms of activist contemporary art.

Abstract This article explores the ties between anti-Black racist kitsch and kawaii culture through the history of the Dakko-chan doll. In what came to be called the “Dakko-chan boom” of 1960, tens of thousands of Japanese people lined up to purchase an inflatable blackface doll with a circular red mouth, grass skirt, and winking hologram eyes. Dakko means “to hug,” and Dakko-chan's astronomical popularity resulted in part from the way the doll could be worn as an accessory, attached to the body by its hugging arms. This article asks what it meant for Japan, a nation still recovering from World War II and the American occupation, to quite literally embrace American blackface in the form of an embraceable doll. Rejecting the claim that blackface loses its significance in a Japanese context, this article argues that Dakko-chan cannot be considered devoid of racist meanings. Emerging amid the political turmoil surrounding the revision of the US-Japan Security Treaty, Dakko-chan came to express a wide range of contradictory feelings about race, sex, and nation, illustrating how affective attachments to racist forms have accrued rather than dissipated through their movement into new cultural contexts.

The complex relation between gender and the representation of intellectual authority has deep roots in European history. Portraits and Poses adopts a historical approach to shed new light on this topical subject. It addresses various modes and strategies by which learned women (authors, scientists, jurists, midwifes, painters, and others) sought to negotiate and legitimise their authority at the dawn of modern science in Early Modern and Enlightenment Europe (1600–1800). This volume explores the transnational dimensions of intellectual networks in France, Italy, Britain, the German states and the Low Countries. Drawing on a wide range of case studies from different spheres of professionalisation, it examines both individual and collective constructions of female intellectual authority through word and image. In its innovative combination of an interdisciplinary and transnational approach, this volume contributes to the growing literature on women and intellectual authority in the Early Modern Era and outlines contours for future research.

Norm violations have been demonstrated to impact a wide range of seemingly non-normative judgments. Among other things, when agents' actions violate prescriptive norms they tend to be seen as having done those actions more freely, as having acted more intentionally, as being more of a cause of subsequent outcomes, and even as being less happy. The explanation of this effect continues to be debated, with some researchers appealing to features of actions that violate norms, and other researchers emphasising the importance of agents' mental states when acting. Here, we report the results of two large-scale experiments that replicate and extend twelve of the studies that originally demonstrated the pervasive impact of norm violations. In each case, we build on the pre-existing experimental paradigms to additionally manipulate whether the agents knew that they were violating a norm while holding fixed the action done. We find evidence for a pervasive impact of ignorance: the impact of norm violations on non-normative judgments depends largely on the agent knowing that they were violating a norm when acting. Moreover, we find evidence that the reduction in the impact of normality is underpinned by people's counterfactual reasoning: people are less likely to consider an alternative to the agent’s action if the agent is ignorant. We situate our findings in the wider debate around the role of normality in people's reasoning.

Randomized property-based testing has gained much attention recently, but most frameworks stop short at polymorphic properties. Although Bernardy  et al. have developed a theory to reduce a wide range of polymorphic properties to monomorphic ones, it relies upon ad-hoc embedding-projection pairs to massage the types into a particular form. This paper skips the embedding-projection pairs and presents a mechanical monomorphization for a general class of polymorphic functions, a step towards automatic testing for polymorphic properties. The calculation of suitable types for monomorphization turns out to be logarithm .

<div>In this letter, through TCAD simulations, we show that the introduction of a thin paraelectric (PE) layer between the ferroelectric (FE) and dielectric (DE) layers in an MFIS structure, expands the design space for the FE layer enabling hysteresis-free and steep subthreshold behavior, even with a thicker FE layer. This can be explained by analyzing the FE-PE stack from a capacitance perspective where the thickness of the PE layer in the FE-PE stack has the effect of reducing the FE layer thickness, while also reducing the remnant polarization. Finally, for the same FE-PE-DE stack, analog performance parameters such as $\frac{g_{m}} g_{ds}}$ and $\frac{g_{m}}{I_{d}}$ are analyzed, showing good characteristics over a wide range of gate lengths, at low drain voltages, thus demonstrating applicability for low power applications.</div>

Unspecific peroxygenases (UPOs), whose sequences can be found in the genomes of thousands of filamentous fungi, many yeasts and certain fungus-like protists, are fascinating biocatalysts that transfer peroxide-borne oxygen (from H2O2 or R-OOH) with high efficiency to a wide range of organic substrates, including less or unactivated carbons and heteroatoms. A twice-proline-flanked cysteine (PCP motif) typically ligates the heme that forms the heart of the active site of UPOs and enables various types of relevant oxygenation reactions (hydroxylation, epoxidation, subsequent dealkylations, deacylation, or aromatization) together with less specific one-electron oxidations (e.g., phenoxy radical formation). In consequence, the substrate portfolio of a UPO enzyme always combines prototypical monooxygenase and peroxidase activities. Here, we briefly review nearly 20 years of peroxygenase research, considering basic mechanistic, molecular, phylogenetic, and biotechnological aspects.

AbstractPeptide modification methods that do not rely on the cysteine residue are underdeveloped, and their development could greatly expand the current toolbox for peptide chemistry. During the course of preliminary investigations into the classical ortho-phthalaldehyde (OPA)-amine-thiol condensation reaction, we found that in the absence of thiol, OPA readily condenses with two primary alkyl amines to form a class of underexplored isoindolin-1-imine compounds under mild aqueous conditions. From the intramolecular version of this OPA-2amines reaction, an efficient and selective methodology using mild reaction conditions has been developed for stapling unprotected peptides via crosslinking of two amino groups in both an end-to-side and side-to-side fashion. The stapling method is superfast and broadly applicable for various peptide substrates with the reacting amino groups separated by a wide range of different amino acid units. The macrocyclization reactions of selected substrates are completed within 10 seconds at 5 mM concentration and within 2 minutes at 50 μM concentration. Importantly, the resulting cyclized peptides with an isoindolinimine linkage can be extended in a one-pot sequential addition manner with several different electron-deficient π electrophiles, thereby generating more complex structures.

<div>Ultra-thin body (UTB) devices are being used in many electronic applications operating over a wide range of temperatures. The electrostatics of these devices depends on the band structure of the channel material, which varies with temperature as well as channel thickness. The semi-empirical tight binding (TB) approach is widely used for calculating channel thickness dependent band structure of any material, at a particular temperature, where TB parameters are defined. For elementary semiconductors like Si, Ge and compound semiconductors like GaAs, these TB parameters are generally defined at only 0 K and 300 K. This limits the ability of the TB approach to simulate the electrostatics of these devices at any other intermediate temperatures.</div><div>In this work, we analyze the variation of band structure for Si, Ge and GaAs over different channel thicknesses at 0 K and 300 K (for which TB parameters are available), and show that the band curvature at the band minima has minor variation with temperature, whereas the change of band gap significantly affects the channel electrostatics. Based on this finding, we propose an approach to simulate the electrostatics of UTB devices, at any temperature between 0 K and 300 K, using TB parameters defined at 0 K, along with a suitable channel thickness and temperature dependent band gap correction. </div>
