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]

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]

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.)

This article, titled "Comments by Phouphet Kyophilavong on Toward a Green Energy System: How Does Carbon Capture, Utilization, and Storage Technology Innovation Promote Green Total Factor Productivity?" explores the impact of carbon capture, utilization, and storage (CCUS) technology innovation on green total factor productivity (GTFP). The author raises questions about the calculation of GTFP and the advantage of using the Global Malmquist-Luenberger (GML) index. They also inquire about the variables and calculation of the CCUS technology innovation index and suggest conducting tests for normality, nonlinearity, and parameter stability. Additionally, the author recommends including more literature on mediating and moderating roles and addressing multicollinearity problems. [Extracted from the article]
