Multilingual Writing Support

This chapter will provide a research-based protocol for one-to-one writing conferencing that helps tutors and teachers to navigate the tension between standardizing multilingual students' language practices and honoring their rhetorically rich linguistic backgrounds through a series of activities in a ten-week writing center pedagogy course. This series of activities was specifically developed in an effort to respond to writing tutors who are always seeking strategies that effectively apply theoretical principles in practice. While this work focuses specifically on one-to-one writing tutoring, the topic of multilingual writing support is applicable to any English language learning context. By the end of this chapter, readers will have gained a practical strategy centered on using declarative, procedural, and conditional knowledge to help preservice tutors and teachers develop metalinguistic awareness and foster critical consciousness through one-to-one conferencing.

RhodiumIII-Catalyzed Successive Csp2‒H and Csp2‒Csp2 Bond Activation of Aryl Oximes: Synthetic and Mechanistic Studies

Merging selective C–H cleavage with C–C cleavage in a tandem reaction has been a practical strategy that permits skeletal diversification from simple raw materials. Herein, we describe a rhodiumIII-catalyzed redox-neutral...

Iron-Catalyzed decarboxylative and oxidative decarbonylative cross-coupling: A new strategy for the synthesis of monofluoroalkenes

Herein, an iron(II)-catalyzed decarboxylative and oxidative decarbonylative cross-coupling of α-fluoroacrylic acids with aliphatic aldehydes is presented. This methodology provided a novel and practical strategy for the construction of the monofluoroalkenes...

New Open-loop Recycling Approaches for Disposable Diaper Waste

Today's disposable diapers have become an indispensable choice among hygiene products, reflected in their massive global consumption and waste generation. Most of the diaper waste is neither segregated nor treated and ends up in landfills or incinerators. The reported life cycle assessment highlights that the diaper waste is not solely generated after single-use but begins as early as the raw materials acquisition stage. Although what is done cannot be undone, diaper waste can be recycled. Diaper waste valorization has been explored on laboratory- and commercial-scales for years, with varying degrees of success. Leading diaper manufacturers such as Procter & Gamble, Kimberley-Clark and Unicharm are making progress in establishing closed-loop recycling of used diapers and converting diaper waste into new diapers. However, the wide window of possible new products made from diaper waste has yet to be fully exploited. This review focuses on the enormous promise of diaper waste from the perspective of emerging open-loop recycling pathways. We demonstrate that diaper waste was harnessed and converted into non-diaper products, including energy pellets, anode material for lithium-ion batteries, concrete admixture, catalysts, soil amendment, and mushroom cultivation substrates. We also explore several active, commercial-scale diaper recycling approaches and provide a comprehensive blueprint to encourage open-loop recycling. Open-loop recycling is a practical strategy for managing diaper waste, rectifying environmental damage, and contributing to circular supply chains.

Tensor renormalization group and the volume independence in 2D U(N) and SU(N) gauge theories

The tensor renormalization group method is a promising approach to lattice field theories, which is free from the sign problem unlike standard Monte Carlo methods. One of the remaining issues is the application to gauge theories, which is so far limited to U(1) and SU(2) gauge groups. In the case of higher rank, it becomes highly nontrivial to restrict the number of representations in the character expansion to be used in constructing the fundamental tensor. We propose a practical strategy to accomplish this and demonstrate it in 2D U(N) and SU(N) gauge theories, which are exactly solvable. Using this strategy, we obtain the singular-value spectrum of the fundamental tensor, which turns out to have a definite profile in the large-N limit. For the U(N) case, in particular, we show that the large-N behavior of the singular-value spectrum changes qualitatively at the critical coupling of the Gross-Witten-Wadia phase transition. As an interesting consequence, we find a new type of volume independence in the large-N limit of the 2D U(N) gauge theory with the θ term in the strong coupling phase, which goes beyond the Eguchi-Kawai reduction.
