A design framework for enabling sustainability in the clothing sector

This article discusses general strategies to enable environmental sustainability within the clothing sector, providing a framework for decision makers involved in the development of programs and policies for this sector. It initially revises the environmental impact of the clothing system and determines its key environmental sustainability priorities. The framework involves five evolutionary strategies for enabling sustainable consumption and production: 1) environmental improvement of flows throughout the supply chain; 2) environmental redesign of existing clothes; 3) design of new clothes intrinsically more sustainable; 4) design of cloth-service systems and 5) promoting life styles towards sufficient consumption. The practical implications of each strategy is analysed based on correspondent ex-post-facto case studies identified in Brazil, using data collected through literature review and desktop research

The Future of Education: Black Life and Our Classrooms A Moderated Panel Discussion

This piece is an abridged version of a panel discussion that was part of the symposium on Anti-Black State Violence Across the Americas: Power and Struggle in Brazil and the U.S., held at UC Berkeley on February 20–22, 2019, and organized by the LUTA Initiative, a coalition of scholars invested in facilitating international dialogue about racialized state violence across the Americas. The conversation featured Cherrish Cook and Muwazu Chisum-Misquitta (Berkeley High School Student Activists, United States) in conversation with Onirê Onã Walê Borges dos Santos and Andreia Beatriz Silva dos Santos (React or Die/Winnie Mandela Pan-Africanist School, Salvador da Bahia, Brazil). C. Darius Gordon moderated the panel (Editor, Berkeley Review of Education, Graduate School of Education, UC Berkeley). Alejandro Reyes performed transcription and translation for this article.

A New Form of Path Integral for the Coherent States Representation and its Semiclassical Limit

The overcompleteness of the coherent states basis leads to a multiplicity of representations of Feynman's path integral. These different representations, although equivalent quantum mechanically, lead to different semiclassical limits. Two such semiclassical formulas were derived in \cite{Bar01} for the two corresponding path integral forms suggested by Klauder and Skagerstan in \cite{Klau85}. Each of these formulas involve trajectories governed by a different classical representation of the Hamiltonian operator: the P representation in one case and the Q representation in other. In this paper we construct a third representation of the path integral whose semiclassical limit involves directly the Weyl representation of the Hamiltonian operator, i.e., the classical Hamiltonian itself.Comment: 16 pages, no figure

Deformation method for generalized Abelian Higgs-Chern-Simons models

We present an extension of the deformation method applied to self-dual solutions of generalized Abelian Higgs-Chern-Simons models. Starting from a model defined by a potential $V(| \phi |)$ and a non-canonical kinetic term $\omega(| \phi |) | D_{\mu}\phi |^2$ whose analytical domain wall solutions are known, we show that this method allows to obtain an uncountable number of new analytical solutions of new models defined by other functions $\widetilde{V}$ and $\widetilde{\omega}$. We present some examples of deformation functions leading to new families of models and their associated analytic solutions.Comment: 6 pages, 10 figure
