Times flies and it has been close to five and a half years since I became the editor-in-chief of Computational Linguistics on 15 July 2018. In this editorial, I will describe the changes that I have introduced at the journal, and highlight the achievements and challenges of the journal. [ABSTRACT FROM AUTHOR]

What remains of the North American avant-garde of the 1960s and '70s? Certainly many more films than filmmakers, but a paper trail as well. Housed in museums, university libraries, film archives, and personal collections across the United States and Canada, a decentralized and ever-expanding set of documents and ephemera is shaping and informing numerous research-based projects in curation, academic scholarship, and film restoration. And yet, in contrast to this contemporary trend, the collected papers of Michael Snow at the Art Gallery of Ontario in Toronto have yet to be explored in depth. A notable exception is Elizabeth Legge's monograph on Snow's Wavelength (1967), which cites some of the notes he kept during the film's conceptualization and production. 2 Because the analysis of those notes was not one of Legge's primary objectives, however, her book reproduces only three of the pages in Snow's Wavelength file. The occasion of Snow's recent passing will doubtless be met by various forms of retrospection, and this small contribution to that extended moment of reflection makes available in print a greater number of the Wavelength files than have previously been published. They represent a rare instance of a canonical avant-garde film's being accompanied by a significant corpus of scribblings, illustrations, and diagrams. This selection, comprising twenty-four pages taken from the filmmaker's unbound notes, introduces some of the themes and questions that Snow was putting to paper during the project's year of gestation. Below, I offer a few remarks on those pages. They are admittedly somewhat arbitrary, but they are intended to bring to light some of the archive's lesser-known revelations. [ABSTRACT FROM AUTHOR]

Using a panel data set from 2007 to 2019, we empirically evaluate the impact of carbon capture, utilization, and storage (CCUS) technology innovation on green total factor productivity (GTFP). The findings show that (1) CCUS technology innovation significantly improves GTFP. (2) CCUS technology innovation significantly contributes to GTFP by promoting industrial structure upgrading and carbon emissions efficiency. (3) Environmental regulation plays a positive moderating role in the nexus between CCUS technology innovation and GTFP. The findings of this paper provide guidance for China to achieve green energy transition and build a green energy system. [ABSTRACT FROM AUTHOR]

The article offers information related to the financial risk in the age of paper and mentions about trompe l’oeil effect that encourages viewers to misread the artwork as a collection of the actual ephemera it represents. It also mentions that satirical images referencing public discourses and debates, was meant to be read as well as viewed; and information about works of art historian Mark Hallett, is given.

Under the Fascist regime, young Italians amused themselves by practicing the war games of adulthood. Paper soldiers marched across board games set in the newly established empire of Italian East Africa. To reveal how these vicious lessons worked, this article examines three types of toys. It starts with the design and deployment of paper soldiers: Italian Alpinisti, Eritrean Ascari, and Somali Dubat. Next, a playbook for The Conquest of Abyssinia boardgame provides a guide to military conquest. Finally, I examine where these toys come from, revealing the financial structures that underpinned colonial propaganda for Fascist government projects. Ultimately, toys wrote scripts for adult violence in the colonies. [ABSTRACT FROM AUTHOR]

When choices are made from ordered lists, individuals can exhibit biases toward selecting certain options as a result of the ordering. We examine this phenomenon in the context of consumer response to the ordering of economics papers in an e-mail announcement issued by the NBER. We show that despite the effectively random list placement, papers listed first each week are about 30% more likely to be viewed, downloaded, and subsequently cited. We suggest that a model of "skimming" behavior, where individuals focus on the first few papers in the list due to time constraints, would be most consistent with our findings.

This article explores the impact of Carbon Capture, Utilization, and Storage (CCUS) technology innovation on green total factor productivity (GTFP) in China. The study finds that CCUS technology innovation has a positive effect on GTFP by improving industrial structure and carbon emissions efficiency. Environmental regulations also contribute to this relationship. The author suggests further research to refine the measurement of GTFP and address potential issues in the analysis. They also recommend conducting a heterogeneity analysis and mediation test to understand the mechanism of CCUS technology innovation on GTFP. Overall, this study provides valuable insights into the relationship between CCUS adoption and environmental productivity in China. [Extracted from the article]

Behavioral diversity seen in biological systems is, at the most basic level, driven by interactions between physical materials and their environment. In this context we are interested in falling paper systems, specifically the V-shaped falling paper (VSFP) system that exhibits a set of discrete falling behaviors across the morphological parameter space. Our previous work has investigated how morphology influences dominant falling behaviors in the VSFP system. In this article we build on this analysis to investigate the nature of behavioral transitions in the same system. First, we investigate stochastic behavior transitions. We demonstrate how morphology influences the likelihood of different transitions, with certain morphologies leading to a wide range of possible paths through the behavior-space. Second, we investigate deterministic transitions. To investigate behaviors over longer time periods than available in falling experiments we introduce a new experimental platform. We demonstrate how we can induce behavior transitions by modulating the energy input to the system. Certain behavior transitions are found to be irreversible, exhibiting a form of hysteresis, while others are fully reversible. Certain morphologies are shown to behave like simplistic sequential logic circuits, indicating that the system has a form of memory encoded into the morphology-environment interactions. Investigating the limits of how morphology-environment interactions induce non-trivial behaviors is a key step for the design of embodied artificial life-forms., (© 2021 Massachusetts Institute of Technology.)

Does the materiality of a three-dimensional model have an effect on how this model operates in an exploratory way, how it prompts discovery of new mathematical results? Material mathematical models were produced and used during the second half of the nineteenth century, visualizing mathematical objects, such as curves and surfaces—and these were produced from a variety of materials: paper, cardboard, plaster, strings, wood. However, the question, whether their materiality influenced the status of these models—considered as exploratory, technical, or representational—was hardly touched upon. This article aims to approach this question by investigating two case studies: Beltrami's paper models vs. Dyck's plaster ones of the hyperbolic plane; and Chisini's string models of braids vs. Artin's and Moishezon's algebraization of these braids. These two case studies indicate that materiality might have a decisive role in how the model was taken into account mathematically: either as an exploratory or rather as a technical or pedagogical object.
